Prepubertal testicular tumors are rare compared with postpubertal testicular tumors. The incidence of prepubertal testicular tumors peaks at 2 years of age, tapers off after 4 years of age, and then begins to rise again at puberty. Prepubertal and postpubertal testicular tumors show many differences, including the typical tumor histology, molecular biological differences, and the malignant potential of tumors at different ages. Pediatric testicular tumors are classified as benign or malignant on the basis of their clinical behavior and histologically are divided into germ cell and gonadal stromal (nongerm cell) tumors. Many histological and biological studies have further confirmed the distinct nature of prepubertal and postpubertal testicular tumors. These differences have led to various management strategies for prepubertal and postpubertal tumors. Because overall about 75% of prepubertal testicular tumors are benign, a testis-sparing approach is becoming more common in children. Orchiectomy and observation with very selective use of chemotherapy has become the standard approach when a malignant tumor is identified. Retroperitoneal lymph node dissection and radiation therapy play very limited roles.

Testicular microlithiasis (TM) refers to the calcium deposits within the seminiferous tubules. Owing to the wide use of scrotal ultrasonography, more cases of TM have been diagnosed clinically. TM can be associated with many conditions, including cryptorchidism, infertility, varicocele, testicular torsion, Klinefelter's syndrome, intratubular germ cell neoplasia (IGCN) and testicular germ cell tumor (TGCT), and its frequent association with IGCN, TGCT and infertility is the particular concern of urologists and andrologists. The etiology of TM is not yet certain. Its biological meaning and clinical significance have not been well defined. Currently, there are controversies on the correlation of TM with IGCN, TGCT and infertility. This article reviews the definition, prevalence, etiology, and histopathology of TM, and summarized its association with IGCN, TGCT, and male infertility as well as the management of the disease.

We wanted to present the results of our experience with bilateral testis tumor and to suggest the effects of chemotherapy in suppressing the development of second primary testicular tumors. Between 1978 and 1997, 2,345 patients were treated for testicular tumor at The University of Texas M. D. Anderson Cancer Center. Of these, 2,107 had germ cell cancers. There were 22 (0.94%) cases of bilateral testicular tumor in the overall patient population and 21 (1.0%) cases among patients with germ cell cancer. We reviewed the medical records to determine the incidence of the histological subtype, the incidence of metachronous versus synchronous formation of contralateral tumors, and tumor stage in this patient population. We also examined the effect of chemotherapy in treating the first tumor and preventing the occurrence of a second tumor. Finally, we compared the effect of ultrasonography, serum tumor marker elevation, and physical examination in detecting second tumors. Only one contralateral germ cell tumor developed synchronously; all others developed metachronously. Fifty percent of first tumors were seminomas, compared to 55% of second tumors. The histologic concordance rate for first and second tumors was 35%. Tumor stage was higher among first tumors than second tumors. The majority of second tumors in patients who received chemotherapy for first malignancies tended to be metachronous seminomas. Ultrasonography detected 6 of 21 (28.6%) contralateral tumors before they were evident by physical examination or serum tumor marker elevation. Seminomas were more prevalent among patients with bilateral germ cell disease than patients with unilateral disease. Chemotherapy, when used as treatment for first tumors, may have some effect in preventing the development of nonseminomatous germ cell tumors in the contralateral testicle. Close follow-up of the contralateral testis with ultrasonography is essential for early detection of second tumors. The outcome for patients with bilateral testicular germ cell cancer is excellent, secondary to early detection.

PURPOSE: Testicular microlithiasis (TM) is a relatively rare clinical entity of controversial significance characterized by the existence of hydroxyapatite microliths located in the seminiferous tubules. The aim of this study was to observe the natural course of changes in the calcific density of pediatric TM. MATERIALS AND METHODS: We included a total of 23 TM patients undergoing scrotal ultrasound (US) on at least two occasions from July 1997 to August 2014. We retrospectively analyzed the patient characteristics, clinical manifestations, specific pathological features, and clinical outcomes. We measured the calcified area and compared the calcific density between the initial and final USs. RESULTS: The mean age at diagnosis was 11.3+/-4.6 years, and the follow-up period was 79.1+/-38.8 months (range, 25.4-152.9 months). During the follow-up period, no patients developed testicular cancer. Calcific density on US was increased in the last versus the initial US, but not to a statistically significant degree (3.74%+/-6.0% vs. 3.06%+/-4.38%, respectively, p=0.147). When we defined groups with increased and decreased calcification, we found that diffuse TM was categorized into the increased group to a greater degree than focal TM (10/20 vs. 4/23, respectively, p=0.049). In addition, five of eight cases of cryptorchidism (including two cases of bilateral cryptorchidism) were categorized in the increased calcification group. CONCLUSIONS: Diffuse TM and cryptorchidism tend to increase calcific density. Close observation is therefore recommended for cases of TM combined with cryptorchidism and cases of diffuse TM.

The testicular prosthesis can be an afterthought for providers when performing an orchiectomy for testicular cancer, torsion, atrophic testis, or trauma. However, data suggest that patients find the offer of a testicular prosthesis and counseling regarding placement to be extremely important from both a pragmatic and a psychosocial perspective. Only two-thirds of men undergoing orchiectomy are offered an implant at the time of orchiectomy and of those offered about one-third move forward with prosthesis placement. The relatively low acceptance rate is in stark contrast with high patient satisfaction and low complication rates for those who undergo the procedure. The most common postoperative patient concerns are minor and involve implant positioning, size, and weight. Herein, we provide an up-to-date review of modern preoperative evaluation, patient selection, expectation management, surgical technique, and expected outcomes for testicular prostheses.

This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed the directors of 695 institutes where sperm cryopreservation might be performed with questionnaires requesting information on the number of patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, cryopreservation success rate, and causes of unsuccessful cryopreservation. Of these 695 institutes, 92 had cryopreserved sperm before chemotherapy within the study period. In all, 820 cancer patients (237 testicular, 383 hematological, 46 bone and soft tissue, 20 brain, and 134 other malignancy) consulted the responding institutes for sperm cryopreservation. Except for testicular tumor, the number of patients whose sperm was preserved before cancer treatment was low compared to that of young cancer patients. Approximately 20% of patients with malignancies other than testicular tumor underwent chemotherapy before cryopreservation. The success rate of cryopreservation in hematological malignancy was 82.5%, significantly lower than that of both the testicular cancer (93.6%) and other malignancy groups (95.6%) (P < 0.05). The primary reasons for preservation failure were azoospermia and poor semen quality. Patients with hematological malignancies had a higher rate of unsuccessful cryopreservation compared to those in other groups, possibly due to the large number of patients requesting sperm cryopreservation after chemotherapy induction. In Japan, information regarding sperm banking prior to cancer treatment appears to be lacking. Information regarding sperm preservation before chemotherapy should be provided to all Japanese oncologists.

OBJECTIVETo improve the diagnosis and treatment of testicular tumor.

METHODSEighty-seven cases of testicular tumor were retrospectively studied.

RESULTSOf the total number, 79 cases were pathologically diagnosed as germ cell tumor (90.1%), among which there were 44 cases of seminoma (55.7%) and 7 cases of benign tumor (8.1%). Nonseminoma germ cell tumor (NSGCT) was found mainly among those under 5 and from 18 to 40 years of age, while seminoma chiefly among those beyond 17, and testis tumor was rare among those between 5 and 17 years old (1 case only). Three-year and 5-year survival rates of seminoma and NSGCT were 90.6% and 81.3%, and 83.3% and 56.7%, respectively.

CONCLUSION(1) Testicular tumors are mostly germ cell tumors. (2) NSGCT develops mainly among those under the age of 5 and from 18 to 40. (3) Seminoma is rare in those under 18. (4) Testicular tumor rarely develops among those between 5 and 17 years old. (5)Three-year and 5-year survival rates for seminoma are higher than those for NSGCT.

OBJECTIVESTo study the effects of estrogen-like products in milk on the male reproductive system.

METHODSThe incidence rates of testicular and prostatic cancers in 42 countries (regions), collected from the cancer incidence in five continent database (1988-1992), were correlated with the relative food consumption in these countries, which was provided by FAO database (1961-1990); two-generation reproduction test was taken by using Wistar rats according to FDA standard.

RESULTSAmong the food items examined, milk was most closely correlated (r = 0.711) with prostatic cancer incidence, followed by meat and coffee. As for testicular cancer, cheese was most closely correlated (r = 0.804) with the incidences in ages of 20-39, followed by animal fat and milk. No significant decreases of reproductive organ weight were found after the rats had been fed a lot of milk for long time.

CONCLUSIONSThe results suggest that further studies should be taken on the effects of estrogen-like products in milk on the male reproductive health.

This study aims to investigate the effect of different local testicular treatments and validate common prognostic factors on primary testicular lymphoma (PTL) patients. We retrospectively reviewed the clinical records of 32 patients from 1993 to 2017 diagnosed with PTL and included 22 patients for analysis. The Kaplan-Meier method, Log-rank test, and multivariate Cox proportional hazard regression analysis were applied to evaluate progression-free survival (PFS), overall survival (OS), and determine prognosis predictors. The median follow-up time was 30 months. Median OS and PFS were 96 months and 49 months, respectively. In univariate analysis, advanced Ann Arbor stage (III/IV) (P < 0.001), B symptoms (P < 0.001), and extranodal involvement other than testis (P = 0.001) were significantly associated with shorter OS and PFS. In multivariate analysis, Ann Arbor stage was significantly associated with OS (OR = 11.58, P = 0.049), whereas B symptom was significantly associated with PFS (OR = 11.79, P= 0.049). In the 10 patients with the systemic usage of rituximab, bilateral intervention could improve median OS from 16 to 96 months (P = 0.032). The study provides preliminary evidence on bilateral intervention in testes in the rituximab era and validates common prognostic factors for Chinese PTL patients.

Objective: To analyze the clinicopathologic characteristics and prognosis of testicular diffuse large B-cell lymphoma (DLBCL) . Methods: A retrospective analysis was performed on 68 patients with testicular DLBCL admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from October 2001 to April 2020. The gene mutation profile was evaluated by targeted sequencing (55 lymphoma-related genes) , and prognostic factors were analyzed. Results: A total of 68 patients were included, of whom 45 (66.2% ) had primary testicular DLBCL and 23 (33.8% ) had secondary testicular DLBCL. The proportion of secondary testicular DLBCL patients with Ann Arbor stage Ⅲ-Ⅳ (P<0.001) , elevated LDH (P<0.001) , ECOG score ≥ 2 points (P=0.005) , and IPI score 3-5 points (P<0.001) is higher than that of primary testicular DLBCL patients. Sixty-two (91% ) patients received rituximab in combination with cyclophosphamide, adriamycin, vincristine, and prednisone (R-CHOP) -based first-line regimen, whereas 54 cases (79% ) underwent orchiectomy prior to chemotherapy. Patients with secondary testicular DLBCL had a lower estimated 5-year progression-free survival (PFS) rate (16.5% vs 68.1% , P<0.001) and 5-year overall survival (OS) rate (63.4% vs 74.9% , P=0.008) than those with primary testicular DLBCL, and their complete remission rate (57% vs 91% , P=0.003) was also lower than that of primary testicular DLBCL. The ECOG scores of ≥2 (PFS: P=0.018; OS: P<0.001) , Ann Arbor stages Ⅲ-Ⅳ (PFS: P<0.001; OS: P=0.018) , increased LDH levels (PFS: P=0.015; OS: P=0.006) , and multiple extra-nodal involvements (PFS: P<0.001; OS: P=0.013) were poor prognostic factors in testicular DLBCL. Targeted sequencing data in 20 patients with testicular DLBCL showed that the mutation frequencies of ≥20% were PIM1 (12 cases, 60% ) , MYD88 (11 cases, 55% ) , CD79B (9 cases, 45% ) , CREBBP (5 cases, 25% ) , KMT2D (5 cases, 25% ) , ATM (4 cases, 20% ) , and BTG2 (4 cases, 20% ) . The frequency of mutations in KMT2D in patients with secondary testicular DLBCL was higher than that in patients with primary testicular DLBCL (66.7% vs 7.1% , P=0.014) and was associated with a lower 5-year PFS rate in patients with testicular DLBCL (P=0.019) . Conclusion: Patients with secondary testicular DLBCL had worse PFS and OS than those with primary testicular DLBCL. The ECOG scores of ≥2, Ann Arbor stages Ⅲ-Ⅳ, increased LDH levels, and multiple extra-nodal involvements were poor prognostic factors in testicular DLBCL. PIM1, MYD88, CD79B, CREBBP, KMT2D, ATM, and BTG2 were commonly mutated genes in testicular DLBCL, and the prognosis of patients with KMT2D mutations was poor.
