Abstract
PURPOSE It is well known that testicular germ cell tumors arise with increased frequency in patients with cryptorchidism. In addition, intratubular germ cell neoplasia (ITGCN) is a precursor lesion to testicular germ cell tumor. Approximately 50% of patients with ITGCN will develop an invasive of testicular germ cell tumors within 5 years. Therefore, we evaluated that the incidence of ITGCN in postpubertal cryptorchidism. MATERIALS AND METHODS Between January 2002 and August 2012, orchiectomy specimens from 31 postpubertal patients (aged 12 or over) with cryptorchid testis were reviewed. The specimens were evaluated for ITGCN using immunohistochemical stains of placental-like alkaline phosphatase and Oct 3/4 with routine hematoxylin-eosin stain. Additionally, the degree of spermatogenesis was assessed using the Johnsen score. RESULTS Mean age was 34 years (range, 17 to 74 years) at surgery. All patients were diagnosed as unilateral cryptorchidism. One patient (3.2%) of 20-year-old had ITGCN in surgical specimen with all positive markers. Histological assessment of spermatogenesis showed that mean Johnsen score was 3.42 (range, 1 to 9). Majority of patients (27 of 31) presented impaired spermatogenesis with low Johnsen score lesser than 5. CONCLUSIONS Considering the risk of malignancy and low spermatogenesis, we should perform immunohistochemical stains and discuss preventative orchiectomy for the postpubertal cryptorchidism.

Abstract
OBJECTIVES To analyse the calcification of testicular tumours in the orchiectomy specimens detected by digital orchiography obtained in a full-field digital mammography (FFDM) unit. METHODS Orchiectomy specimens of 37 consecutive patients were imaged by FFDM. Detected foci of calcification were stratified as: type 1, dense microcalcification; type 2, faint microcalcification; type 3, macrocalcification. Histopathology identified the tumour types, the presence of intratubular germ cell neoplasia (IGCN) and associated calcifications. Orchiography results correlated with the histopathology. RESULTS On orchiography, 32/37of the specimens (86 %) had co-existing foci of calcification. Histopathology results revealed foci of calcification in 23/37 (62 %) of orchiectomy specimens. Of the 20 IGCN cases, 80 % presented with calcifications on orchiography. Fifty-six percent (14/25) of type 1, 70 % (12/17) of type 2, and 30 % (2/6) of type 3 foci of calcification were observed in IGCN-positive cases. CONCLUSION This study classifies the morphology of testicular tumour calcification in three main groups by digital orchiography. In half of the testicular cancers, histopathologically proven IGCN is also found in addition to the index tumour. Type 2 foci of microcalcification detected by orchiography may be related to IGCN and may prompt further clinical assessment. KEY POINTS • Orchiography can detect and classify calcification in 86 % of testicular cancers. • Intratubular germ cell neoplasia (IGCN) co-exists in 54 % of testicular cancers. • Type 2 foci of microcalcification detected by orchiography may be related to IGCN. • Orchiography may play a possible future role in the diagnosis of testicular IGCN.

Abstract
CONTEXT On behalf of the European Association of Urology (EAU), guidelines for the diagnosis, therapy, and follow-up of testicular cancer were established. OBJECTIVE This article is a short version of the EAU testicular cancer guidelines and summarises the main conclusions from the guidelines on the management of testicular cancer. EVIDENCE ACQUISITION Guidelines were compiled by a multidisciplinary guidelines working group. A systematic review was carried out using Medline and Embase, also taking Cochrane evidence and data from the European Germ Cell Cancer Consensus Group into consideration. A panel of experts weighted the references, and a level of evidence and grade of recommendation were assigned. RESULTS There is a paucity of literature especially regarding longer term follow-up, and results from a number of ongoing trials are awaited. The choice of treatment centre is of the utmost importance, and treatment in reference centres within clinical trials, especially for poor-prognosis nonseminomatous germ cell tumours, provides better outcomes. For patients with clinical stage I seminoma, based on recently published data on long-term toxicity, adjuvant radiotherapy is no longer recommended as first-line adjuvant treatment. The TNM classification 2009 is recommended. CONCLUSIONS These guidelines contain information for the standardised management of patients with testicular cancer based on the latest scientific insights. Cure rates are generally excellent, but because testicular cancer mainly affects men in their third or fourth decade of life, treatment effects on fertility require careful counselling of patients, and treatment must be tailored taking individual circumstances and patient preferences into account. TAKE HOME MESSAGE Although testicular cancer has excellent cure rates, the choice of treatment centre is of the utmost importance. Expert centres achieve better results for both early stage testicular cancer (lower relapse rates) and overall survival (higher stages within clinical trials). For patients with clinical stage I seminoma, adjuvant radiotherapy is no longer recommended as first-line adjuvant treatment.

Abstract
We analyzed characteristics, therapy and outcome of patients with bilateral testicular germ cell tumor (TGCT) at our institutions. Among 1,180 TGCT patients diagnosed and/or treated between 1979 and 2003, 47 (4.0%) developed a second TGCT. Nine of 14 patients (64%) with synchronous TGCT are alive with no evidence of disease (NED) at a median follow-up of 37 months. Thirty-three patients had a metachronous bilateral TGCT. Median time to the 2(nd) TGCT was 71 months. At diagnosis of 2(nd) TGCT 30 patients had stage I, 1 had stage II and 2 had stage III disease. Thirty-two of 33 patients are alive with NED at a median follow up of 41 months. No patient died from second TGCT. As a review of the literature confirms our data we do not recommend a routine biopsy of the contralateral testicle for early detection of testicular intraepithelial neoplasia (TIN).

Abstract
Patients with a prior history of a germ cell tumor of the testicle are known to have an increased risk of development of a second germ cell tumor in the contralateral testicle. It is believed that all patients who develop a germ cell tumor of the testicle have a precursor lesion know as carcinoma in situ (CIS) or intratubular germ cell neoplasia. Approximately 50% of these patients will subsequently go on to develop a germ cell tumor in the testicle. A biopsy of the contralateral testicle in a patient with a previous history of a germ cell tumor of the testicle has been advocated by some, while others recommend a biopsy only in patients with other risk factors as well. The arguments for biopsy are that intervention may be used to prevent the development of a second germ cell tumor when CIS is detected. In this review we present the arguments for and against a biopsy of the contralateral testicle, review the techniques of biopsy as well as its complications, and discuss the interventions employed to prevent CIS from progressing.

Abstract
Germ cell tumors are derived from cells of the germ cell lineage and are the most common solid malignancies to affect young Caucasian men between the ages of 15 and 40 years. All testicular germ cell tumors develop from the same precursor lesion, intratubular germ cell neoplasia unclassified, which in turn is thought to arise from malignant transformation of a primordial germ cell or gonocyte. These tumors are characterized by extreme chemosensitivity and are considered a model for curative disease. In spite of this, a small subset of patients with metastatic disease fail to achieve a complete response with cisplatin-based chemotherapy or relapse from complete remission. Understanding the molecular biology may help the design of new therapies for those patients with a poor prognosis and could also improve the treatment of cancer in general. Current understanding of the role of genetic and epigenetic factors in the etiology of germ cell tumors and the biochemical mechanisms underlying chemotherapy sensitivity and resistance is discussed in detail in this review.

Abstract
Testicular vein sampling is a well-known technique in the investigation of testicular function, or in determining the origin of certain plasma protein markers. We describe the application of this technique in the case of a patient who had previously undergone right radical orchidectomy for testicular teratoma, to discover the source of persistently raised tumour markers following the operation. We found this diagnostic tool useful in avoiding unnecessary procedures of the remaining testis and in guiding further treatment.

Abstract
Urologic malignancies are common, accounting for approximately 25% of all new cancer cases in the United States. Patients with urologic malignancies require long-term surveillance to detect progression or recurrence as early as possible. The urologist is faced with the task of balancing patient safety and cost-effectiveness, while finding the most practical follow-up regimen. For each urologic malignancy, this article reviews the commonly used radiologic techniques for surveillance and offers recommended follow-up schedules.

Abstract
OBJECTIVE Testicular biopsy has recently gained a role in early detection of testicular cancer. However, its use is still limited mainly because of the fear of untoward consequences. There is a paucity of data regarding unfavourable effects of testicular biopsy. Therefore, we systematically looked to the consequences of the procedure by using clinical observational methods and by modern imaging techniques, respectively. PATIENTS, METHODS 1874 patients with testicular cancer enrolled in a nation-wide contralateral biopsy study were prospectively analyzed in regard to surgical complications. Serial scrotal imaging was performed by scrotal sonography (7.5 Mhz) in 55 patients and by magnetic resonance tomography (1.5 Tesla machine, surface coil, contrast media) in 60 patients, respectively. Imaging examinations were done preoperatively and again at 1 week, 6 months, 12 months, and 18 months respectively. Imaging results were tabulated according to an abnormality score and analyzed by descriptive statistics. RESULTS 52 patients (2.78%; 95% confidence intervals 2.05-3.60) experienced surgical complications. Forty minor complications were managed conservatively. Twelve patients (0.64%) required repeat surgery; 1 testicle was ultimately lost following a sequence of unfortunate events. No pre-existing clinical parameter was associated with complications. One week after surgery, abnormalities were detected in 33% by sonography and in 45% by MRI, respectively. Importantly, the abnormalities resolved in 96% of the cases, as found in both of the imaging modalities in the serial scans. CONCLUSIONS Testicular biopsy is associated with a low burden of clinically significant complications. However, scrotal imaging discloses intratesticular abnormalities in a high proportion of cases one week after the biopsy. These changes represent focal haematoma, oedema or circumscript injury to vascular supply. Most of these lesions resolve with time and are thus not significant, clinically. Evidently, testicular biopsy is a safe procedure provided the vascular anatomy of the testis is respected upon surgery.

Abstract
BACKGROUND Although risk estimates for synchronous and metachronous contralateral testicular cancers vary widely, many clinicians recommend routine biopsy of the contralateral testis for patients diagnosed with unilateral testicular cancer. We evaluated the risk of contralateral testicular cancer and survival in a large population-based cohort of men diagnosed with testicular cancer before age 55 years. METHODS For 29 515 testicular cancer cases reported to the National Cancer Institute's Surveillance, Epidemiology and End Results Program from 1973 through 2001, we estimated the prevalence of synchronous contralateral testicular cancer, the observed-to-expected ratio (O/E) and 15-year cumulative risk of metachronous contralateral testicular cancer, and the 10-year overall survival rate of both synchronous and metachronous contralateral testicular cancer, using the Kaplan-Meier method for the two latter assessments. Age-adjusted multivariable analyses were used to examine risk according to histologic type of the original cancer. RESULTS A total of 175 men presented with synchronous contralateral testicular cancer; 287 men developed metachronous contralateral testicular cancer (O/E = 12.4 [95% confidence interval {CI} = 11.0 to 13.9]; 15-year cumulative risk = 1.9% [95% CI = 1.7% to 2.1%]). In the multivariable analysis, only nonseminomatous histology of the first testicular cancer was associated with a statistically significantly decreased risk of metachronous contralateral testicular cancer (hazard ratio [HR] = 0.60, 95% confidence interval [CI] = 0.46 to 0.79; P<.001). Increasing age at first testicular cancer diagnosis was associated with decreasing risk of nonseminomatous metachronous contralateral testicular cancer (odds ratio = 0.90, 95% CI = 0.86 to 0.94). The 10-year overall survival rate after metachronous contralateral testicular cancer diagnosis was 93% (95% CI = 88% to 96%), and that after synchronous contralateral testicular cancer was 85% (95% CI = 78% to 90%). CONCLUSIONS The low cumulative risk of metachronous contralateral testicular cancer and favorable overall survival of patients diagnosed with metachronous contralateral testicular cancer is in accordance with the current U.S. approach of not performing a biopsy on the contralateral testis.

Abstract
To define guidelines for the follow-up management of patients treated for testicular germ cell tumor this study assessed characteristics of patients with recurrent disease. The charts of 505 patients with testicular cancer treated and followed-up at the University Medical Centre Nijmegen between 1982-2000 were reviewed retrospectively. In 42 patients disease recurrence was found during routine follow-up. In a subset of patients no recurrences were seen after first-line treatment: (a) pathological stage IIa nonseminoma patients who were adjuvantly treated with chemotherapy and (b) histologically confirmed complete responders after primary chemotherapy. Furthermore, in low-stage disease no intra-abdominal recurrences were seen in (a) pathological stage I nonseminoma patients and (b) low-stage seminoma patients who received radiotherapy. The risk of recurrent testicular cancer depends on primary therapy and efficacy of it; these results indicate a limited role for follow-up in pathological stage II nonseminoma patients adjuvantly treated with chemotherapy and in histologically confirmed complete responders after chemotherapy. Abdominal computed tomography does not appear necessary in routine follow-up of patients treated for low-stage testicular cancer.

This paper is the result of a meeting of the European Association of Pathologists, Uropathology Division in Florence 2003. The aims of this meeting were to establish: guidelines for specimen handling by urologists and minimum requirements for data accompanying testicular specimens submitted to pathologists; a consensus on techniques for processing specimens by pathologists; the essential information required from pathology reports; areas where our standard practice is traditional rather than evidence based and where further studies are required. The general aims of histopathology are to give or confirm a diagnosis; assess established prognostic markers; identify changes associated with treatment; provide information for audit (i.e. imaging, urology and pathology) and maintain a permanent record (slides/blocks).

Abstract
The aim of this study was to describe the incidence, clinical and histological characteristics, treatment and long-term follow-up of bilateral germ-cell tumours (BGCT) of the testis in order to determine in what respects they differ significantly from unilateral germ-cell tumours. In all, 31 patients with BGCT had metachronous tumours and 14 had synchronous tumours. Among the metachronous tumours, 61% occurred more than 5 years after the first tumour. The overall incidence of BGCT in patients with testicular germ-cell tumours (TGCT) was 1.9%. The incidence was 3.2% in patients presenting with a seminoma and 1.4 % in patients presenting with a nonseminomatous germ-cell tumour (NSGCT). Patients under 30 years of age at the time of the initial diagnosis had a higher incidence of bilateral tumours compared with older men. The outcome of BGCT was excellent. A high association was found between BGCT, sterility and suspected genetic risk factors for TGCT. These results argue against a systematic contralateral biopsy at diagnosis of first TGCT in all patients, but emphasise the importance of patient education and of the need to better identify patients at risk for a second TGCT. Therapeutic indications for synchronous BGCT, including conservative treatment, need to be better defined.

Abstract
Seminoma is characterized by high sensitivity to both radiation and chemotherapy. Localized recurrences in the retroperitoneum after surveillance for stage I can be treated with radiotherapy; however, multiple or large bulky retroperitoneal recurrences or systemic metastasis requires cisplatin-based chemotherapy. Salvage chemotherapy for those who recur after initial CR to induction chemotherapy is based on ifosfamide- and cisplatin-containing regimens. Incomplete response or failure after induction chemotherapy requires high-dose chemotherapy and stem cell rescue. Patients with seminoma need long-term follow-up because of the possibility of late recurrence and the risk of a second primary tumor.

Abstract
This review serves as an outline of the clinical features and management options for the majority of recurrence situations in NSGCTs. The combination of reliable serum tumor markers, improved imaging techniques, effective cisplatin chemotherapy regimens, and application of meticulous surgical techniques has resulted in dramatic improvements in cure rates in NSGCT. These factors have caused the incidence of recurrent NSGCT to decline substantially in the past 20 years. This rarity of recurrence in combination with the low incidence of NSGCT prevents the practicing clinician from accumulating experience in this challenging patient population. Therefore, to ensure improvement in salvage rates, patients are best managed in centers with extensive experience in NSGCT.

Abstract
Germ cell tumours (CT) are no true carcinomas; therefore the term testicular intraepithelial neoplasia (IN) is probably more appropriate than "CIS". The diagnostic accuracy of a single-site biopsy is an open question. We experienced 9 false-negative biopsies among 1859 cases. Thus, the proportion of a failed diagnosis is 0.5%. The main reason for diagnostic failure is the non-random distribution of TIN within the testicle. Currently we are investigating whether a two-site biopsy is more accurate than a single biopsy. In the ongoing trial, the over-all prevalence of TIN is around 5.3%, so far. In one quarter of the positive cases the lesion was found in only one of the two specimens. Thus, a double biopsy appears to be more favourable than the traditional single biopsy. Surgical complications amount to 2.5% in that double biopsy study. Only one surgical re-intervention was required among 983 patients. Serial imaging studies with scrotal sonography and magnetic resonance imaging (MRI) disclosed a transient intratesticular haematoma/oedema postoperatively. So, testicular biopsy, even when performed at two sites is in fact a low-complication procedure. Low dose radiotherapy to the testis is the treatment of choice for TIN. However, more than one quarter of patients require testosterone supplementation secondary to androgen-deficiency. Two dose-reduction studies (Denmark and Germany) had to be terminated prematurely because unexpected relapse of TIN was encountered at 14 Gy and 16 Gy. Possibly, hyperfragmentation schedules can overcome the antagonism of androgenic compromise and oncological safety. In a nation-wide survey, it was shown that contralateral biopsies were routinely performed in 66% of the urological departments in Germany. Another 19% offered the biopsy to particular "risk-cases"; only 15% never did a biopsy. Among those refusing biopsies, there was a higher proportion of small hospitals and a significantly lower annual case-number of GCT, when compared to those doing the biopsy. Thus, the contralateral biopsy is a well-established procedure among German urologists; those with a high caseload of GCT particularly appreciate it.

Abstract
OBJECTIVE [corrected] To evaluate the clinical-pathological significance of the intratesticular calcification. MATERIAL AND METHODS We analyzed by scrotal U.S., transducer 6.5 Mhz, the patients that consulted about testicular painful, infertility or intrascrotal deformity. Biopsy was effectuated when detected size modification of testicles, and central or focal calcifications. Also was done the classics tumoral markers. We founds 16 patients with microlithiasis over 24 testicles with these pathology. Previous antecedents: infertility 6 cases, testicular devolvulations surgery 5c, bilateral orchidopexy 3c and unilateral epididymitis 2c. The calcifications was classified in: peripheric or central follow-up 26.4 months. RESULTS Associated pathology: a) Bilateral cryptorchidism: 4 testicles. b) Testicular tumors: 5 testicles. These tumors were biopsed: 3 seminomas, 1 embryonary carcinoma and 1 ca in situ. Both with negative biologic markers. The association with testicular tumor had an incidence of 20.83%. The central localization was detected in the 5 tumors, while the peripheric were 4 testis (cryptorchidism) and 15 with aspect of "snow storm". Histopathologically was observed eosinophilic bodies, with calcified nucleus, but not a exclusive features. CONCLUSIONS Is a benign condition, casual, whose clinical significance is a still enigma. The association with testicular tumor is 20.83% and associated pathology is 33%. We proposed a testicular biopsy in cases of microlithiasis focal, central or with previous pathology.

Abstract
A new indication for testicular tissue cryopreservation is demonstrated in a patient with metachronous bilateral testicular tumours and azoospermia. At the age of 18 (1982) the patient underwent left orchidectomy and radical retroperitoneal lymphadenectomy for a testicular teratoma (pT1N0M0). Semen samples were not cryopreserved because of absence of motile spermatozoa after thawing. Seventeen years after the primary testicular cancer, a seminoma of the contralateral right testis was diagnosed (pT1N0M0). Since the patient was azoospermic, no semen samples could be cryopreserved. However, spermatozoa were detected in testicular biopsy material of the right testis and were cryopreserved for ICSI. Since all spermatozoa were dead after thawing, testicular sperm extraction (TESE) was performed in the remaining tissue samples at the time of ICSI treatment. Only spermatids could be extracted from frozen-thawed samples due to the inhomogeneous distribution of spermatogenic activity in the testicular tissue. Although one oocyte was fertilized with these spermatids, a clinical pregnancy was not achieved. Despite the disappointing results of ICSI in the couple presented here, this case report demonstrates that cryopreservation of testicular tissue and TESE should be considered in patients with bilateral testicular tumours and azoospermia, if frozen semen samples are not available.

Abstract
Carcinoma in situ (CIS) of the testis is a common precursor of germ-cell tumours in adults and adolescents, with the exception of spermatocytic seminoma. This article reviews existing knowledge on the pathobiology, genetic aspects and epidemiology of CIS, discusses current hypotheses concerning pathogenesis and invasive progression of germ-cell neoplasms and provides guidelines for diagnosis and clinical management of CIS.

Abstract
In the last 20--30 years the availability of effective chemotherapy and more accurate clinical staging has greatly improved the prognosis for patients with testicular germ cell tumours. Initially, such treatment appeared to diminish the role of histopathology to the distinction between seminoma and nonseminomatous germ cell tumour (NSGCT) in the primary specimen. However, histopathology has evolved as a prognostic tool indicating the risk of relapse in various defined clinical contexts thereby facilitating therapeutic decisions. The clinical emphasis has been on quality of life and reduction of therapy both in terms of the number of patients treated and the number of chemotherapy courses given to each patient. The treatment of adult testicular germ cell tumours may differ between countries but protocols are established. Therefore it is appropriate to discuss the role of histopathology during this era of relative therapeutic stability.

Abstract
OBJECTIVES To assess the characteristics of patients with recurrent disease by a retrospective analysis. METHODS Between 1982 and 1998, 488 patients were treated in Nijmegen for testicular cancer. All patients underwent orchiectomy and adjuvant treatment when indicated. Patients were routinely followed up. RESULTS In 36 patients (7.4%), disease recurrence was found during follow-up; 12 had contralateral disease and 24 systemic recurrence. Contralateral testicular cancer occurred a median of 63.8 months (range 43.2 to 165.2) after orchiectomy and systemic recurrence at a median of 6.1 months (range 1.5 to 94.4). Contralateral testicular cancer was more frequent in patients with pure seminoma (odds ratio 4.3, 95% confidence interval 1.4 to 13.1); 8 of 9 patients with contralateral cancer received adjuvant radiotherapy. The best predictor of systemic recurrence after nonseminoma germ cell tumor was the presence of teratoma and embryonal cell components in the primary tumor. In the entire population, 19 patients (3.9%) died of the disease. None of the patients with contralateral testicular recurrence or systemic recurrence after Stage I seminoma died of the disease. One of 10 patients died of recurrent Stage I nonseminoma germ cell tumor. The chance of dying of recurrence after metastatic nonseminoma germ cell tumor was 36%. CONCLUSIONS Recurrence after an initially complete response is rare in testicular cancer. Contralateral testicular cancer is associated with the presence of seminoma components in the primary tumor and occurs almost 10 times later than systemic recurrence. The prognosis after contralateral testicular cancer and after recurrence in Stage I seminoma is good.

Abstract
OBJECTIVE To know the prevalence of the bilateral germ cell tumours of testis diagnosed in our Department and to review the literature. MATERIAL AND METHODS 64 patients diagnosed of a germ cell tumour of the testis were followed during an average period of 51.4 months (1-168 months). RESULTS 5 (7.8%) patients developed a second germ cell testicular tumour. In one patient the tumours were synchronous while in the remaining four were metachronous, occurring in an average interval of 59 months. One patient with a metachronous tumour died as consequence of the second tumour. In two of the five patients risk factors were identified, one presented testicular atrophy and the second referred history of undescended testis. DISCUSSION The probability of developing a germinal testis tumour between the patients with history of a previous germ cell tumour of the testis is sensibly greater than between the general population. The prevalence of the bilateral tumours of the testis oscillates between 1-5% and approximately 75% will be metachronous. The principal factor that can predict the appearance of a second testicular tumour is the presence of the carcinoma in situ (Cis) in the contralateral testicular biopsy. Except in cases of testicular atrophy or previous history of undescended testis we do not recommend routine biopsy of the other testis.

Abstract
BACKGROUND AND OBJECTIVE Preventive measures are commonly classified into primary (prevention of a disease from occurring), secondary (screening of asymptomatic persons with a view of early detection and treatment of disease), and tertiary (treatment of patients with a view of palliation, cure, rehabilitation, prevention of relapse, or prevention of complications). The objective of the present survey was to assess the adherence to this classification in a sample of abstracts of scientific publications. METHOD We searched the literature (key terms prevention and primary, secondary, or tertiary) and identified 317 abstracts describing various preventive interventions. We tabulated the level of prevention as defined in the abstract, by what was done, to whom, and why. MAIN FINDINGS There was a considerable variability in the way the various levels of prevention were defined in the reviewed abstracts. CONCLUSIONS The definitions of the levels of prevention are not specific enough to be appropriately used by all. We suggest, therefore, to define clinical interventions by their objective, target population, and type ("reduction of mortality of patients with symptomatic ventricular ectopy by beta-blockers"), rather than in terms of level of prevention ("tertiary prevention of ventricular ectopy").

Abstract
We report the case of a 20-year old male with a right testicular tumor. Bilateral orchidectomy was practised considering the synchronous clinical, ultrasonographical and histological (intraoperative biopsy) findings of the left testis. The definitive pathological report showed a right embryonal carcinoma with wide intratubular germ cell neoplasia (IGCN) of the contralateral testis. IGCN (formerly carcinoma in situ) is present in about 5% of cases in the contralateral gonad of those patients with a testicular neoplasm. More than 50% will develop cancer in that testis. Clinical and physical examination findings are usually unspecific. The diagnosis of IGCN is based on biopsy, although ultrasonography could give some data too, as some authors report. We analyze the therapy options for IGCN: (orchidectomy, chemotherapy, radiotherapy, or "wait and see"). In our case, the first one was made. Chemotherapy was used due to existence of retroperitoneal lymph node metastases, with an excellent follow-up afterwards.

Abstract
Carcinoma in situ of the testis (CIS) is the uniform precursor of testicular germ-cell tumours. Morphologically, CIS consists of large, intratubular, gonocyte-like cells with large nuclei and abundant glycogen. CIS cells are probably derived from primordial germ cells and are supposed to be present in the testis of a future testis cancer patient at the time of birth. CIS cells appear to spread inside the seminiferous tubules until CIS progresses to invasive cancer. Diagnosis is best achieved by surgical biopsy of the testis and subsequent immunohistological staining of placental alkaline phosphatase (PlAP). This enzyme is present in embryonal germ cells, CIS and seminoma as well as several other types of germ-cell tumour but usually not in normal germ cells. CIS is found in testicular tissue adjacent to testicular germ-cell tumours in about 90% of cases, and it is observed in all clinical groups known to be at risk for testicular cancer: cryptorchidism (2% to 4%), infertility (0% to 1%), ambiguous genitalia (25%) and contralateral testis of patients with testicular cancer (5%). Conversely, CIS is found in less than 1% of the normal male population, and this prevalence corresponds well to the life-time risk of testicular cancer in males. If CIS is left untreated, there is a 50% probability of progressing to frank germ-cell neoplasm within 5 years. Localised low-dose radiotherapy to the testis eradicates CIS and germ cells, while Leydig cells are preserved. The patient can thus be spared orchiectomy and hormone supplementation. Currently, dose-reduction studies are looking for the optimal radiation dose, which is expected to be around 14 to 16 Gy. After chemotherapy, there is a cumulative risk of 42% for recurrence of CIS within 10 years. The concept of CIS offers the chance of very early detection of testicular cancer and organ-preserving early treatment.

Abstract
Testicular seminoma is highly curable with currently available treatments. Today, there is good evidence that patients with Stage I disease can be treated equally well with either immediate adjuvant para-aortic and ipsilateral pelvic radiotherapy or close surveillance with treatment at the time of relapse. The decision as to which of these management strategies is adopted in an individual case is a complex function of physician preference, and the emotional, social, and economic circumstances of the patient. Ongoing research in Stage I seminoma is focused at reducing the side-effects of treatment either by modifying the radiation treatment plan or by using adjuvant chemotherapy in lieu of radiation. Stage II patients with small bulk retroperitoneal lymphadenopathy have a high probability of long-term disease control with radiotherapy. Patients with bulky Stage II disease or Stage III disease should be treated with cisplatin-based chemotherapy.

Abstract
OBJECTIVES To determine whether the clinical course or the histopathologic risk factor assessment of the secondary tumor justifies early detection of the premalignant testis, since only 5% of contralateral testicular biopsies in the case of a testicular tumor reveal a testicular intraepithelial neoplasia (TIN). METHODS From 1975 to 1997, 30 patients with bilateral germ cell tumors were treated; histologic and clinical data were available in all patients. In 12 patients, histopathologic re-evaluation and immunohistochemical staining of both tumors was performed for risk factor analysis. RESULTS At the time the primary tumor was diagnosed, the mean patient age was 28 years. The metachronous secondary tumors were detected after a mean of 5.6 years. Seminoma was the predominant histologic finding in primary (53%) and secondary (56%) tumors. Eighty-three percent of patients had clinical Stage I (Lugano classification) disease at the diagnosis of the secondary tumor and 17% Stage II. Only 3 of 12 secondary tumors showed vascular invasion. The proliferation analysis (MIB-I score) showed a mean proliferation rate of only 34% within the primary and 26% within the secondary tumors. CONCLUSIONS The results of our study show that the low clinical stage and good outcome associated with a histologic low-risk score of the secondary tumor does not mandate contralateral biopsy to detect TIN at the time of diagnosis of the first tumor.
