Validity of prognostic models: when is a model clinically useful?
SO - Semin Urol Oncol 2002 May;20(2):96-107
AD - Center for Clinical Decision Sciences, Department of Public Health,
Erasmus University Rotterdam, The Netherlands.
Prognostic models combine patient characteristics to predict medical
outcomes. Unfortunately, such models do not always perform as well for
other patients as those from whose data the models were derived.
Therefore, validity of prognostic models needs to be assessed in new
patients. Predicted probabilities can be calculated with the model and
compared with the actually observed outcomes. We may distinguish several
aspects of validity: (1) agreement between predicted probabilities and
observed probabilities (calibration), (2) ability of the model to
distinguish subjects with different outcomes (discrimination), and (3)
ability of the model to improve the decision-making process (clinical
usefulness). We discuss those aspects and show some measures by using
models for testicular and prostate cancer. We conclude that good
calibration and discriminative ability are not sufficient for a model to
be clinically useful. Application of a prognostic model is sensible, if
the model is able to provide useful additional information for clinical
decision making. Copyright 2002, Elsevier Science (USA). All rights

OBJECTIVE: To describe an additional case of an uncommon variant of
Sertoli cell testicular tumor. METHODS/RESULTS: A 34-year-old male
infected with the human immunodeficiency virus presented with a right
testicular tumor he had noted one year earlier. A right inguinal
orchidectomy was performed. Histological examination demonstrated
sclerosing Sertoli cell tumor. CONCLUSIONS: Sertoli cell tumor is a rare
variant of testicular tumor from sexual cords. Although it is uncommon,
histological variants have been described: classical Sertoli cell tumor,
large calcifying cells and the sclerosing variant. The case of
sclerosing Sertoli cell tumor described herein is a variant of which 11
cases have been reported in the world literature. The fact that our
patient is HIV-positive makes this case even rarer.

Universitario, Malaga, Espana.
OBJECTIVE: To describe the clinical and histological findings of a case
of renal cell carcinoma metastatic to the testes, an uncommon site of
metastasis of this tumor type that can cause difficulty in making the
differential diagnosis and consequently, in the staging and treatment of
the disease. METHODS/RESULTS: A 65-year-old patient diagnosed of renal
cell carcinoma presented a paratesticular mass. Histopathological
examination of the orchidectomy specimen showed proliferation of clear
cells arranged in a diffuse pattern, with intimate intertwining with
vascular structures. Tumor cells were strongly positive for vimentin,
CAM5.2 and EMA. CONCLUSIONS: Although renal cell carcinoma rarely
metastasizes to the testes, it should be considered in the differential
diagnosis of testicular masses. Histological examination is essential to
diagnosis and correct management.

INTRODUCTION: Hereditary persistence of alpha-fetoprotein is a rare
disorder which exists with no simultaneous disease. The tenth case in
the world (two brothers with seminoma and their father) is documented
and a complete literature review was done. EXEGESIS: It is transmitted
as an autosomal dominant; a disease point mutation has been identified.
The failure to recognize hereditary persistence of alpha-fetoprotein
sometimes involves unjustified treatments. CONCLUSION: The occurrence of
this situation is probably underestimated and it could explain residual
levels of alpha-fetoprotein.

Testicular microlithiasis: prospective analysis of prevalence and
associated tumor.
SO - Radiology 2002 Aug;224(2):425-8
AD - Mallinckrodt Institute of Radiology, Washington University School of
Medicine, 510 S Kingshighway Blvd, St Louis, MO 63110, USA.
PURPOSE: To evaluate testicular microlithiasis (TM) prospectively with
modern state-of-the-art equipment. MATERIALS AND METHODS: Information
concerning indication for examination, presence and degree of TM,
presence of testicular tumor, and patient age was prospectively recorded
for all patients referred for scrotal ultrasonography between 1996 and
1999. High-frequency linear transducers (7.5 MHz or higher) were used.
TM was divided into classic (CTM) and limited (LTM) on the basis of the
presence of five or more microliths on one or more images of the testes.
Fisher exact tests were used for determining significant differences in
proportions. RESULTS: Data in 1,079 patients were analyzed. The overall
prevalence of TM was 18.1% (195 of 1,079). Forty (3.7%) patients had
CTM, and 155 (14.4%) had LTM; 15 (1.4%) had tumors visible at US. Tumors
were present in three (8%) of 40 patients with CTM (seminoma in two,
embryonal cell in one), nine (5.8%) of 155 with LTM (seminoma in six,
mixed germ cell in one, Leydig cell in two), and three (0.3%) of 884
with no TM (seminoma in two, other in one). There was no difference
between CTM and LTM (P =.72) in the rate of coexisting tumor. There was
a significant difference between no TM and CTM or LTM (P =.001) in the
rate of coexisting tumor. Eighty percent (12 of 15) of patients with
tumor at presentation had CTM or LTM. CONCLUSION: Approximately one of
27 patients had CTM, and one of seven had LTM. Although a majority of
patients with testicular tumors had coexistent TM, more than 90% with TM
(both CTM and LTM) did not have tumor at presentation. Copyright RSNA,

Mature teratoma arising in intraabdominal undescended testis in an
infant with previous inguinal exploration: case report and review of
intraabdominal testicular tumors in children.
SO - J Pediatr Surg 2002 Aug;37(8):1236-8
AD - Department of Pediatric Surgery, Kiyama Hospital, Kawasaki, Japan.
The authors report the youngest case of postoperative intraabdominal
mature testicular teratoma in a 5-year-old boy after previous
exploration for impalpable testis. A total of 26 cases of intraabdominal
testicular tumor in children including our case were reviewed and
discussed from both the English- and the Japanese-language literature.
The average age was 2.5 years, and, in the 13 children younger than 1
year there were no malignant teratomas, although there was one immature
teratoma. Four of these had undergone previous inguinal exploration in
which 3 patients except our patient were more than 10 years old. This
case report confirms the importance of finding an intraabdominal testis
at operation for impalpable testis. Early detection of the testicular
location near the internal inguinal ring in these patients supports the
hypothesis that the intraabdominal testicular teratoma itself may have
been the primary cause of the undescended testis. Furthermore, it is
suspected that many of the intraabdominal testicular malignant teratomas
in adults may have arisen from these mature testicular teratomas in
infants. Copyright 2002, Elsevier Science (USA). All rights reserved.

Laparoscopic retroperitoneal lymph node dissection after chemotherapy.
SO - Urology 2002 Jul;60(1):130-4
AD - Department of Surgery, Division of Urology, University of Maryland
Medical System, Baltimore, Maryland, USA.
OBJECTIVES: To assess the operative feasibility, clinical outcomes, and
complications of laparoscopic retroperitoneal lymphadenectomy (RPLND)
after chemotherapy. METHODS: A retrospective review of clinical records
from 7 patients who underwent laparoscopic RPLND after chemotherapy was
performed. Five patients presented with nonseminomatous germ cell tumor
after orchiectomy. One patient was diagnosed with pure seminoma and one
with epididymal small cell cancer. All 7 patients received multiagent
chemotherapy for clinical Stage IIA or higher disease, followed by
laparoscopic RPLND for findings of a residual retroperitoneal mass on
computed tomography or a prechemotherapy mass size greater than 3.0 cm.
The mean tumor diameter was 3.07 cm before chemotherapy and 1.91 cm
after chemotherapy. A modified laparoscopic left (n = 3), right (n = 3),
and bilateral (n = 1) template was used. None of the patients had
received radiotherapy before surgery. RESULTS: Postchemotherapy
laparoscopic RPLND was successfully completed in 5 (71.4%) of 7
patients. Two patients required a conversion to open surgery. The
overall complication rate was 57.1% (4 of 7), with a major complication
incidence of 42.8% (3 of 7). No mortalities were recorded. Of the 5
patients who presented with nonseminomatous germ cell tumor after
orchiectomy, 3 were found to have retroperitoneal lymph nodes consistent
with mature teratoma, 1 had necrotic tissue, and 1 had residual viable
tumor. CONCLUSIONS: Laparoscopic RPLND is a feasible operation in
patients after systemic chemotherapy. This technique remains challenging
at this time and should be reserved for patients with limited residual
disease and should only be performed at institutions with considerable
laparoscopic expertise.

A 20% dose reduction of the original CISCA/VB regimen allows better
tolerance and similar survival rate in disseminated testicular
non-seminomatous germ-cell tumors: final results of a phase III
randomized trial.
SO - Ann Oncol 2002 Jan;13(1):125-34
AD - Department of Genitourinary Medical Oncology, The University of Texas
M.D. Anderson Cancer Center, Houston, USA. fizazi@igr.fr
BACKGROUND: This prospective randomized clinical trial was designed to
compare the efficacy of a low-dose regimen of cisplatin, doxorubicin and
cyclophosphamide alternated with vinblastine and bleomycin (CISCA/VB)
with the original CISCA/VB regimen in patients with disseminated
nonseminomatous germ-cell tumors (NSGCT) and a predicted favorable
outcome. PATIENTS AND METHODS: One hundred and twenty-five patients with
disseminated NSGCT and a predicted favorable outcome according to the
M.D. Anderson Cancer Center classification [testicular primary and human
chorionic gonadotropin (hCG) serum level <50000 mIU/ml] were randomized
to receive the original CISCA/VB regimen (100% dose) or a low-dose
CISCA/VB regimen (80% dose). RESULTS: Among the 124 eligible patients,
there was no significant difference in the number of patients in the two
treatment arms who achieved a complete response to therapy: 53 of 65
patients (82%) on the original CISCA/VB regimen and 53 of 59 patients
(90%) on the low-dose CISCA/VB regimen (P = 0.29). Overall, the original
CISCA/VB regimen resulted in a significantly higher relative dose
intensity (P <0.0001). After a median follow-up of 6.8 years (range 0.37
to 12.94 years), there was no significant difference in disease-free
survival (P = 0.87) or in overall survival (P = 0.88) between the two
treatment arms. The 5-year overall survival rate was 93.7% [95%
confidence interval (CI) 88% to 100%] and 94.1% (95% CI 84% to 100%) in
the original CISCA/VB arm and the low-dose CISCA/VB arm, respectively.
The 5-year overall survival rate for the entire study population was 98%
(95% CI 94% to 100%) and 88% (95% CI 76% to 100%) in the good- and
intermediate-prognosis groups, respectively, as defined by the
International Germ Cell Consensus Classification Group (IGCCCG). The
low-dose CISCA/VB regimen resulted in significantly less neutropenic
fever (P <0.001), grade 4 thrombocytopenia (P <0.03) and severe
mucositis (P <0.01) than the original CISCA/VB regimen. CONCLUSIONS:
CISCA/VB is highly efficient in patients with good or intermediate
prognosis NSGCT according to the IGCCCG criteria. Although equivalent
antitumor efficacy cannot be claimed, the low-dose CISCA/VB regimen
appears to be a better mode of delivery than the original CISCA/VB
regimen with respect to toxicity, since survival is comparable.

How should a man with testicular cancer be counseled and what
information is available to him?
SO - Semin Urol Oncol 1996 Feb;14(1):17-23
AD - Department of Psychiatry, Harvard Medical School and the Department of
Medical Oncology, Dana Farber Cancer Institute, Boston, MA, USA.
The peak incidence of testicular cancer occurs in early adulthood
(between the ages 19 to 34) when men are physically robust and actively
formulating social and sexual identities. This is also a time when they
are pursuing career and family goals. The disease not only interrupts
these pursuits but its very location threatens the integrity of the body
and an organ that is associated with self-esteem, sexuality, fertility,
and masculinity-psychosocial issues of importance to both ill and
healthy men alike. This paper discusses approaches to counseling these
men. Effective counseling depends on understanding the illness itself
and four psychosocial domains: the context of patients' lives, the
assault on the sense of self, the impact on intimate relationships, and
treatment options and psychosexual effects.

Effect of hypoxia on human seminoma cells.
SO - Int J Oncol 2002 May;20(5):955-62
AD - Department of Urology, Kawasaki Medical School, Okayama 701-0192, Japan.
Since hypoxia has been considered to enhance metastatic potential in
solid tumors via a neo-angiogenesis caused by vascular endothelial cell
growth factors (VEGFs) induced by hypoxia inducible factor-1alpha
(HIF-1alpha), the effects of hypoxia on human seminoma cell lines were
examined in terms of growth, morphology, gene expression, protein
expression and cell cycle perturbation. Growth was inhibited in
long-term cultures with morphological changes to the spindle form. The
gene expression of VEGF-C was markedly enhanced and the production of
VEGF-A increased during hypoxia, although HIF-1alpha was not upregulated
at the protein or message level. Hypoxic culture caused G1 cell cycle
arrest with upregulation of the p15/ink4b and p27/Kip1 genes, whereas no
increase of apoptotic cells was observed on up-regulation of the heat
shock protein (HSP) 70 gene. The adhesion molecules were only slightly
altered.

BACKGROUND: Survival of pediatric patients with malignant germ cell
tumors has improved dramatically with the use of cisplatin-based
chemotherapy, though patients are at high risk of significant long-term
complications. In a prospective study, carboplatin was substituted for
cisplatin in an attempt to minimize nephro- and oto-toxicities, while
achieving excellent disease-free survival. PROCEDURE: All consecutive
patients with malignant germ cell tumors at The Children's Hospital of
Philadelphia were treated between 1989 and 1998. After pathologic
confirmation of disease and pretreatment evaluation of pulmonary, renal,
and otologic function, patients received etoposide 150 mg/m(2) days 1,
2, 3; carboplatin 600 mg/m(2) day 2; and bleomycin 10 mg/m(2) day 3 for
at least four courses. RESULTS: Twenty-three patients were entered for
study, and were available for evaluation. All patients achieved either a
complete or partial remission following therapy with surgery and
chemotherapy. With a median of 58 months of follow-up, overall survival
is 91% and event-free survival is 87%. Therapy was given as an
outpatient, and well tolerated, with 20 admissions for fever and
neutropenia. Ototoxicity and nephrotoxicity, when evaluated, have been
extremely limited. Three patients, all with stage III disease, have
relapsed; one of these remains alive and disease free. CONCLUSIONS:
Carboplatin can successfully substitute for cisplatin during the
treatment of pediatric germ cell tumors without sacrificing response or
survival. Long-term effects, especially nephrotoxicity and ototoxicity,
were rare or mild among the small number of patients evaluated.
Carboplatin appears to be a safe and efficacious alternative in the
treatment of germ cell tumors, and should be considered as primary
therapy for pediatric patients. Copyright 2002 Wiley-Liss, Inc.

Testicular function following chemotherapy.
SO - Hum Reprod Update 2001 Jul-Aug;7(4):363-9
AD - Department of Endocrinology, Christie Hospital NHS Trust, Manchester,
UK.
Testicular dysfunction is a common long-term sequela of cytotoxic
chemotherapy used in the treatment of many malignancies. The degree to
which testicular function is affected is dose- and agent-dependent. The
impact on germinal epithelial function of standard multi-agent regimens
used in the treatment of lymphomas has been widely studied.
Procarbazine-containing regimens result in azoospermia in the vast
majority of patients, but much lesser degrees of long-term
gonadotoxicity are apparent with the newer forms of chemotherapy.
High-dose chemotherapy used as preparation before bone marrow transplant
is also associated with irreversible germinal epithelial failure in the
majority of men. Treatment of testicular cancer with cisplatin and
carboplatin regimens leads to temporary azoo- and oligozoospermia in
most men, with a recovery to normospermia in 80% by 5 years. There is
also evidence of mild Leydig cell impairment in a proportion of men
treated with cytotoxic agents, although the clinical significance of
this is not clear. Several methods of preserving testicular function
during potentially sterilizing treatment have been considered. At
present, sperm banking remains the only proven method, although hormonal
manipulation to enhance recovery of spermatogenesis and cryopreservation
of testicular germ cells are possibilities for the future.

Testicular implants and patient satisfaction: a questionnaire-based
study of men after orchidectomy for testicular cancer.
SO - BJU Int 2001 Oct;88(6):559-62
AD - Department of Urology, Watford NHS Trust, Linda Jackson Centre and
Department of Medical Oncology, Mount Vernon Hospital, Middlesex, UK.
OBJECTIVES: To assess the satisfaction of men with their testicular
implants after undergoing orchidectomy for testicular cancer, and to
determine their reasons for accepting or declining a prosthesis.
PATIENTS AND METHODS: In all, 424 men who had undergone radical
orchidectomy and were part of the testicular cancer follow-up programme
were sent an anonymous questionnaire comprising 10 questions covering
two main areas. First, the reasons for accepting or declining an implant
and second (if they received an implant) their satisfaction with the
size, position, feel, shape and overall comfort; 234 men (55%)
responded. RESULTS: About a third (71 men) accepted an implant, a third
declined and a third were not offered the choice. Of the men who replied
91% felt that it was extremely important to be offered an implant at the
time of surgery. Of the 71 who received an implant, 19 (27%) were
dissatisfied and felt that they had an average or poor cosmetic result.
The reasons for this dissatisfaction are presented and discussed.
CONCLUSIONS: All men undergoing orchidectomy should be offered a
testicular implant, irrespective of age. Sample implants in all sizes
should be available in the outpatient department. This will give men
realistic expectations and allow them to choose a suitable size of
implant. The dimensions of the available implants should be improved to
create a more elliptical prosthesis, to avoid dissatisfaction with the
shape. Adequate fixation to the base of the scrotum is important to
avoid the 'high riding' implant.

Ultrasound guided needle localization and microsurgical exploration for
incidental nonpalpable testicular tumors.

AD - Center for Male Reproductive Medicine and Microsurgery, Cornell
Institute for Reproductive Medicine, New York Weill Cornell Medical
Center, New York, NY 10021, USA.
PURPOSE: We describe a technique by which incidental, nonpalpable
intratesticular tumors are excised using intraoperative ultrasonography
and the operating microscope. MATERIALS AND METHODS: Men with impalpable
intratesticular tumors incidentally detected by ultrasonography
underwent intraoperative ultrasound guided needle localization and
microsurgical exploration of the mass. The testis was delivered through
an inguinal incision and placed on ice to minimize warm ischemia. Two
rubber shod vascular clamps were placed across the spermatic cord. The
tumor was identified by ultrasound and localized with a 30 gauge needle,
which was placed adjacent to the tumor. An operating microscope
providing 6x to 25x magnification was used to excise the lesion with a 2
to 5 mm. margin. Tissue diagnosis was obtained by frozen section.
Multiple random biopsies of the remaining parenchyma were done to
confirm absent malignancy. RESULTS: Ultrasound showed incidental,
nonpalpable testis tumors in 4 of the 65 men who underwent infertility
evaluation and were entered into the microsurgical testis biopsy
hypoechoic. Frozen section analysis of the lesions revealed 2 Leydig
cell tumors, 1 mass with an inconclusive pathological diagnosis and 1
inflammatory mass. On permanent section the latter 2 lesions were
seminoma. The seminomas were 1.6 and 0.9 cm. in the greatest diameter,
and the Leydig cell tumors were 0.35 and 0.2 cm., respectively. Random
biopsies were positive for seminoma and intratubular germ cell neoplasia
in both testes with seminoma. These 2 patients subsequently opted to
undergo radical orchiectomy. No residual tumor was detected in either
radical orchiectomy specimen. CONCLUSIONS: Intraoperative ultrasound
guided needle localization with microsurgical exploration is a safe and
effective approach to even small impalpable testicular masses. This
technique provides the opportunity to identify and remove benign and
malignant lesions, and preserve the testis when the lesion is benign. In
cases of a solitary testis or bilateral synchronous lesions the
technique allows a potentially testis sparing operation for small
malignancies.

Testicular cancer.
SO - Curr Opin Oncol 2002 May;14(3):260-4
AD - University of Michigan Medical Center, Ann Arbor, Michigan 48019, USA.
Testicular cancer remains a major success story in the realm of solid
tumors. Although testicular cancer is highly treatable and curable,
there are still many young men who succumb to the disease. Over the past
year, important data regarding the diagnosis, treatment, and prognosis
of testicular cancer have been reported. The significance of genetic and
molecular alterations, such as i12p and epidermal growth factor receptor
expression, remain at the forefront of research. However surgery and
platinum-based chemotherapy are still the main treatment modalities.
Attempts to limit chemotherapy and surgery while preserving cure rates
are promising. The contribution of long-term platinum retention to the
well-documented risk of late toxicity is unknown but provides a specific
avenue for research. New tumor markers, such as lactate dehydrogenase
isoenzyme-1, may provide a greater risk stratification. Positron
emission tomography imaging may reduce the need for surgical resection
posttherapy and provide a more comprehensive means of observation.

Altered expression of connexins 26 and 43 in Sertoli cells in
seminiferous tubules infiltrated with carcinoma-in-situ or seminoma.
SO - J Pathol 2002 Aug;197(5):647-53
AD - Institute of Veterinary Anatomy, University of Giessen, Germany.
The expression of connexins (cx) 26 and 43 in testis infiltrated with
carcinoma-in-situ (CIS) or seminoma was examined to gain insight into
the relationship between aberrant gap junctional communication and
spermatogenic impairment in the neoplastic testis. In uninvolved tubules
with normal spermatogenesis, cx43 immunostaining was localized to the
Sertoli-Sertoli junctional complex and cx26 was absent. In contrast,
infiltrated tubules with spermatogonial arrest or CIS-only were negative
for cx43, but displayed strong intracytoplasmic Sertoli cell staining
for cx26. The Sertoli cells in these tubules re-expressed cytokeratin 18
(ck18), signifying a reversion to a less differentiated state. Western
blot analysis for cx43 revealed a single immunoreactive band at 43 kD
(normal spermatogenesis) and three bands at 43, 41, and 39 kD (impaired
spermatogenesis with CIS or seminoma). For cx26, a doublet band at 26/28
kD (normal spermatogenesis) and an additional doublet band at 52/54 kD
(impaired spermatogenesis with CIS or seminoma) were observed. The
altered expression of cx26 and cx43 in Sertoli cells in testes
infiltrated with CIS or seminoma suggests that a derangement in
intercellular communication between Sertoli cells and between Sertoli
cells and germ cells may play a role in the resulting spermatogenic
impairment and possibly in the proliferation and neoplastic progression
of CIS cells. Copyright 2002 John Wiley & Sons, Ltd.

autonomous nosographic entity. The reported case is peculiar because the
patient was older than the most ones described in the literature and the
tumour arose after polychemotherapy for non Hodgkins' disease. The
Authors analyse some aspects concerning etiology, pathology and clinical
approach to such rare neoplasm.

Fine-needle aspiration biopsy of nonteratomatous germ cell tumors of the
mediastinum.
SO - Am J Clin Pathol 2002 Sep;118(3):418-24
AD - Department of Pathology, University of Alabama at Birmingham, USA.
We assessed the usefulness of fine-needle aspiration biopsy (FNAB) in
the diagnosis of mediastinal germ cell tumors (GCTs). In the archives of
3 pathology departments, we found records of 7 patients with mediastinal
GCTs who underwent mediastinal FNAB as part of the diagnostic workup.
The FNAB smears, results of the immunocytochemical analysis, the
corresponding histologic findings, and the clinical charts were
reviewed. All patients were men (age range, 24-44 years; mean, 32
years). One patient had a history of testicular mixed GCT 10 years
earlier. The 6 primary mediastinal GCTs consisted of 3 seminomas and 3
yolk sac tumors. Based on the cytologic features and
immunocytochemicalfindings, a cytologic diagnosis of GCT was made in 5
cases, including the case of metastatic GCT In 2 cases, the differential
diagnosis was between poorly differentiated carcinoma and GCT Results of
ancillary studies were noncontributory in 1 case, and the aspirate of
the second case demonstrated extensive necrosis. Our findings
demonstrate that a diagnosis of mediastinal GCT, primary or secondary,
can be established with a high degree of accuracy on the basis of FNAB.
Immunocytochemical analysis helps confirm the diagnosis.

A case of clear cell adenocarcinoma of the mullerian duct in persistent
mullerian duct syndrome: the first reported case.
SO - Am J Surg Pathol 2002 Sep;26(9):1231-4
AD - Department of Pathology, Kakegawa City General Hospital, Kakegawa,
Japan.
We report a case of a 67-year-old man with clear cell adenocarcinoma of
the remnant uterus in persistent Mullerian duct syndrome. He had a
normal penis, urethra, and scrotum, and there was also a vagina and
uterus. He died in a traffic accident, and clear cell adenocarcinoma was
discovered incidentally at autopsy. Clear cell adenocarcinoma of the
remnant uterus metastasized to the retroperitoneal lymph nodes and
bilateral lungs. Persistent Mullerian duct syndrome is characterized by
the persistence of Mullerian derivatives in otherwise normally virilized
males. A variety of germ cell tumors of the testis have been reported in
association with persistent Mullerian duct syndrome. However, no
malignant change of the persistent Mullerian duct structures has been
reported. This represents the first reported case of malignant change of
the persistent Mullerian duct structures in persistent Mullerian duct
syndrome.

Bilateral cryptorchidism with bilateral inguinal hernia and retrovesical

SO - J Laparoendosc Adv Surg Tech A 2002 Feb;12(1):73-5
AD - Department of Urology, All India Institute of Medical Sciences, New
Delhi.
A 30-year-old married man presented with the complaint of inability to
procreate. Examination revealed bilateral nonpalpable testes and
bilateral inguinal hernia. Ultrasonography of the abdomen could not
locate the testis; instead, a hypoechoic 5 x 5-cm mass was found behind
the bladder. A CT scan of the abdomen revealed the right testis near the
right inguinal canal. The left testis could not be identified beside the
soft tissue mass. The patient was taken for diagnostic as well as
therapeutic laparoscopy. The testis on the right was found just proximal
to the internal inguinal ring, and right orchidopexy was done. The left
testis was small and rudimentary; hence, orchidectomy was done.
Bilateral laparoscopic herniorrhaphy was carried out with polypropylene
mesh by fixing it intracorporeally to the pubic bone, Cooper's ligament,
inguinal ligament, and conjoint tendon. Subsequently, the retrovesical
mass was excised and retrieved by dilating the umbilical port site. The
operative time was 3.5 hours with minimal blood loss. The postoperative
period was uneventful, and the patient was discharged after 24 hours.
The histopathology examination of the retrovesical mass showed an
extragonadal germ cell tumor compatible with seminoma.

No association between human parvovirus B19 and testicular germ cell
cancer.

The incidence of testicular germ cell cancer, which is the most common
cancer among young male adults, is increasing. The aetiology remains
unknown, although a virus has been proposed. A previous study has shown
a high prevalence of human parvovirus B19 (B19) DNA in the testes of
patients with testicular germ cell tumours (85%) and suggested that B19
may play a role in tumour development. To address this question of
causality, seroreactivity to B19 was studied among cases (n=80) and
controls (n=241) using serum samples drawn before the onset of disease,
in addition to an elucidation of the frequency of virus DNA in a
retrospectively collected 2-year testicular carcinoma series. No
association was found between B19 seropositivity and the risk of
testicular cancer (odds ratio=1.03; 95% confidence interval=0.60-1.77)
nor was there any dose-response relation (P for trend=0.53). This study
did, however, confirm the observation that B19 DNA can be detected in
testicular carcinoma tissue, as 4 of 24 cases were found to be positive,
while no B19 DNA could be detected in the control cases. It is
speculated that this finding may be due to susceptibility of the
carcinoma cells to B19 virus owing to high-level expression of the viral
receptor glycosphingolipid (Gb4) and possible other putative cellular
factors resulting in a localized persistence initiated after the
development of cancer.

Bilateral testicular germ cell tumors: twenty-year experience at M. D.
Anderson Cancer Center.
SO - Cancer 2002 Sep 15;95(6):1228-33
AD - Department of Pathology, The University of Texas M. D. Anderson Cancer
Center, Houston 77030, USA.
BACKGROUND: The incidence of testicular carcinoma in the United States
has increased significantly over the last two decades. Germ cell tumors
form the majority of malignant testicular tumors. With advances in
diagnosis and therapeutic approaches, germ cell tumors are now highly
sensitive to treatment, providing long-term survival. It has been
speculated that the incidence of bilateral germ cell tumors may increase
due to the improved survival of patients with unilateral germ cell
tumors. In this report, the authors present a study of bilateral germ
cell tumors of the testis in men who were treated at The University of
Texas M. D. Anderson Cancer Center over a 20-year period with emphasis
on their incidence, histologic features, and clinical features. METHODS:
Between 1978 and 1999, 2431 patients with testicular germ cell tumors
were treated at The University of Texas M. D. Anderson Cancer Center.
Among these, 24 patients with bilateral germ cell tumors were
identified. Clinical records and all available pathology slides of the
tumors were reviewed. RESULTS: The overall incidence of bilateral germ
cell tumors in the patients with testicular germ cell tumors was 1% (24
of 2431 patients). The incidence was 1.8% (14 of 776 patients) in
patients with seminoma and 0.6% (10 of 1655 patients) in patients with
nonseminomatous germ cell tumors. Patients with seminoma who were age
= 30 years at the time of initial diagnosis had a higher incidence of
bilateral tumors compared with older men. Twenty of 24 patients with
bilateral germ cell tumors had metachronous tumors, and 4 patients had
synchronous tumors. Among the patients with metachronous tumors, 70% of
second tumors occurred within 5 years; the longest interval between the
first and second tumors was 15 years. The outcome of patients with
bilateral germ cell tumors was excellent; only 1 of 24 patients died of
metastatic disease. CONCLUSIONS: The overall incidence of bilateral
testicular germ cell tumors was 1% in patients who were treated at The
University of Texas M. D. Anderson Cancer Center over the past two
decades. The incidence of bilateral germ cell tumors was related to the
histologic type of the initial tumor and to the patient's age at initial
presentation in patients with seminoma. Thus, patients in the second or
third decade of life who presented with seminomas as their initial tumor
were more likely to develop a second germ cell tumor compared with
patients in the fourth or fifth decade of life. These findings have
potentially important implications for clinical management by
identifying a population of patients with germ cell tumors who are at
risk of developing a second tumor and also for studying risk factors of
bilateral germ cell tumors of the testis. Copyright 2002 American Cancer

Expression of cancer testis genes in human brain tumors.
SO - Clin Cancer Res 2000 Oct;6(10):3916-22
AD - Department of Medicine, Saarland University Medical School, Homburg,
Germany.
Cancer-testis (CT) genes are expressed in a variety of human cancers but
not in normal tissues, except for testis tissue, and represent promising
targets for immunotherapeutic and gene therapeutic approaches. Because
little is known about their composite expression in human brain tumors,
we investigated the expression of seven CT genes (MAGE-3, NY-ESO-1,
HOM-MEL-40/SSX-2, SSX-1, SSX-4,HOM-TES-14/SCP-1, and HOM-TES-85) in 88
human brain tumor specimens. Meningiomas expressed only HOM-TES-14/SCP-1
(18% of meningiomas were HOM-TES-14/SCP-1 positive) and did not express
any other CT genes. One ependymoma was negative for all CT genes tested.
SSX-4 was the only CT gene expressed in oligodendrogliomas (2 of 5
cases), and it was also expressed in oligoastrocytomas (3 of 4 cases)
and astrocytomas (10 of 37 cases). Astrocytomas were most frequently
positive for HOM-TES-14/SCP-1 (40%) and SSX-4 (27%), followed by
HOM-TES-85 (13%), SSX-2 (11%), and MAGE-3 (7%). Whereas MAGE-3 was
detected only in grade IV astrocytomas, the expression of the other CT
genes showed no clear correlation with histological grade. Of 39
astrocytomas, 60% expressed at least one CT gene, 21% expressed two CT
genes, and 8% coexpressed three CT genes of the seven CT genes
investigated. We conclude that a majority of oligoastrocytomas and
astrocytomas might be amenable to specific immunotherapeutic
interventions. However, the identification of additional tu-mor-specific
antigens with a frequent expression in gliomas is warranted to allow for
the development of widely applicable polyvalent glioma vaccines.

Expression patterns of cancer testis antigens in testicular germ cell
tumors and adjacent testicular tissue.
SO - J Urol 2001 May;165(5):1790-4
AD - Department of Urology, Shiga University of Medical Science, Otsu, Shiga,
Japan.
PURPOSE: The human cancer-testis antigens (CTAs) are a group of tumor
specific antigens recognized by cytotoxic T lymphocytes whose expression
occurs in human malignancies as well as in normal testicular tissue. We
studied a series of CTA gene transcripts in testicular germ cell tumors
of various histological types to test the hypothesis that the expression
of CTA in testicular germ cell tumors reflects developmental stages of
tumorigenesis rather than constitutive tumor antigens recognized by
cytotoxic T lymphocytes. MATERIALS AND METHODS: Total RNA was obtained
from 31 primary and 3 metastatic testicular germ cell tumors, and 11
parenchymal tissues adjacent to the testicular germ cell tumors. We
performed an expression study of the CTA genes MAGE-A, MAGE-B, GAGE,
PAGE-1, HOM-MEL-40 (SSX2), NY-ESO-1, LAGE-1 and SCP-1 in these samples
using reverse transcriptase-polymerase chain reaction. RESULTS: The
results showed that expression patterns of CTA genes depended on the
histological differentiation of the testicular germ cell tumors. Overall
CTA expression was more common in seminomas than in nonseminomatous germ
cell tumors. Specifically all 13 seminomas (100%) demonstrated the
positive expression of MAGE-B1 and MAGE-B2, while 3 of 17
nonseminomatous germ cell tumor samples (18%) showed positive expression
of these genes. All 5 teratomatous elements (100%) had homogenous null
expression with regard to all CTA genes examined. In addition, we
detected deficiencies in CTA expression in 7 of 11 parenchymal tissues
adjacent to the testicular germ cell tumors (64%). CONCLUSIONS: These
data support the idea that CTA transcripts in testicular germ cell
tumors serve as developmental footprints of testicular germ cell tumors
rather than as constitutive tumor antigens recognized by cytotoxic T
lymphocytes.

MAGE-A4, a germ cell specific marker, is expressed differentially in
testicular tumors.
SO - Cancer 2001 Dec 1;92(11):2778-85
AD - GERM-INSERM U. 435, Universite de Rennes I, Campus de Beaulieu,
Bretagne, France.
BACKGROUND: Testicular germ cell tumors are the most common malignancy
in young males, and the frequency of these tumors has risen dramatically
over the last century. Because it is known that the MAGE genes are
expressed in a wide variety of tumors but are expressed only in the
mitotic spermatogonia (germ cells) and in the primary spermatocytes in
the normal testis, the authors screened the expression of MAGE-A4 in a
panel of testicular germ cell tumors. METHODS: Monoclonal antibody 57B
raised against MAGE-A4 was tested immunohistochemically on 12 classical
seminomas, 5 anaplastic seminomas, 10 various specimens of
nonseminomatous germ cell tumors (NSGCTs), 2 combined tumors containing
seminoma components, 1 Sertoli cell tumor, 2 Leydig cell tumors, and 15
carcinomas in situ (CIS). In addition, monoclonal antibody 57B was
tested on embryonic gonad (age 8 weeks) and fetal gonads (ages 15 weeks,
17 weeks, and 28 weeks). RESULTS: Classical seminomas uniformly and
specifically expressed MAGE-A4 compared with anaplastic seminomas and
NSGCTs, which were negative for this antigen. Specific expression of
MAGE-A4 also was seen in subpopulations of CIS cells, providing
additional evidence for heterogeneity of the phenotype of these cells,
in which it is believed that differentiation and proliferation generate
seminomas and NSGCTs. Finally, MAGE-A4 was expressed in the fetal
precursors of the stem germ cells from 17 weeks of gestation onward, in
accordance the fact that CIS can arise from prespermatogonia in the
fetus. CONCLUSIONS: MAGE-A4 can be considered a potential specific
marker for normal premeiotic germ cells and germ cell tumors and can be
used to characterize classical seminomas. Copyright 2001 American Cancer

Cancer/testis genes are potential targets for therapeutic genetic and
immunologic approaches, and are highly expressed in a large variety of
human cancers. However, they are not expressed in normal tissues, with
the exception of the testis. The NY-ESO-1 gene is the most recently
identified member of the cancer/testis family and its product is one of
the most immunogenic tumor antigens. We used immunohistochemistry to
investigate the expression of NY-ESO-1 in healthy human prenatal and
adult testes and in 59 human t
