One case was misdiagnosed. Surgical management was carried out in 42 cases and postoperational radiation therapy or chemotherapy was performed. The 1–5 year postoperative survival rate was totally 100%.Conclusion: B-ultrasound, especially color Doppler flow imaging, with the advantages of noninvasiveness and inexpensiveness was most useful and should be firstly employed in diagnosing the testicular tumor. The favorable prognosis can be obtained if an early diagnosis is made and the early treatment is performed. Key words testicular tumor - B-ultrasound - color Doppler flow imaging展开更多

Case presentation: We report a patient who presented with a tumor that slowly grew at the left lower abdominal port site 1 year after post-chemotherapy laparoscopic retroperitoneal lymph node dissection (RPLND) for metastatic testicular tumor. The enlarging mass mimicking port site recurrence after laparoscopic retroperitoneal lymph node dissection for metastatic testicular tumor was diagnosed as a desmoid tumor. Conclusion: To our knowledge, this is the first report of a desmoid tumor that developed after laparoscopic RPLND for a testicular tumor.展开更多

It can be physiological or pathological. Gynecomastia can be a sign for testicular tumors including sex-cord stromal tumors and germ cell tumors. Testicular physical examination in combination with testicular untrasonography and serum germ cell tumor markers when necessary in the presence of gynecomastia can help to reach a correct diagnosis.展开更多

The aim of our study was to report the diagnostic and evolutionary aspects of testicular cancer cases treated in our center. Patients and Methods: A retrospective study conducted over a 15-year period involving 12 patients treated for testicular cancer at the University Hospital of Brazzaville. Results: The median age was 31 years (range 11 to 49 years), with a median consultation delay of 10.6 months (range 3 to 27 months). Scrotal mass was the most common reason for consultation. Cancer was bilateral in two patients. Two patients were admitted with metastatic disease. Histopathological examination favored germ cell tumors in 7 cases, two cases of non-Hodgkin’s malignant lymphoma, and one case of epididymo-testicular adenocarcinoma. Adjuvant chemotherapy resulted in complete remission in patients with germ cell tumors. However, neoadjuvant chemotherapy was not effective in patients admitted with advanced-stage disease. Conclusion: Testicular cancer is a rare condition that is curable in the majority of cases, but its management is often complicated in our setting due to delayed diagnosis caused by taboos surrounding genital organ pathologies.展开更多

Thus far,...The molecular basis for enhanced chemosensitivity of testicular germ cell tumors （GCT） has been an area of great interest, as it could potentially give us therapeutic leads in other resistant malignancies. Thus far, however, the increased sensitivity of C＆T has been variously attributed to multiple factors -- an inability to detoxify cisplatin, a lack of export pumps, an inability to repair the DNA damage, an intact apoptotic cascade and lack of p53 mutation; but a unifying underlying etiology leading to the aforementioned processes and having a translational implication has so far been elusive. Herein, we offer evidence to support a potential significant role for the previously demonstrated low hypoxia inducible factor-la （HIF-la） expression in mediating the general exquisite chemosensitivity of testicular GCT, through the aforementioned processes. This molecular mechanism based hypothesis could have a significant translational implication in platinum refractory GCT as well as other platinum resistant malignancies.展开更多

However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cell tumors, we analyzed the outcomes(relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months(range, 4 months to 17 years) were enrolled in this study. In 20 cases(83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients(76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively(P = 0.042), and the 3-year overall survival rates were 90.5% and 100%, respectively(P = 0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cell tumors.展开更多

The authors report the case of a young Senegalese 21, who has consulted for an occlusive syndrome evolving for 48 hours that prompted his hospitalization. Note that the patient has consulted several times to persistent inguinal scrotal pain, a big right purse with chronic analgesic requirements and anti-inflammatory. Occlusive before this table, abdominal pelvic CT was performed and highlighted the presence of lung metastases, a large pelvic lymph node casting bridging the inter vesico-rectal space and responsible for extrinsic compression of the small intestine, lymph node inter casting aorto-cellar and latero aortic liver and multiple secondary locations. Faced with this bundle of arguments, clinical and laboratory, metastatic testicular tumor was raised and measured tumor markers. A right orchiectomy by inguinal was made with histology: A non-seminomatous germ cell tumor stage III. After orchiectomy germinal markers were still high and there was the problem of persistent occlusive syndrome despite resuscitation. A chemotherapy regimen was initiated with 4 cycles of chemotherapy according to the protocol BEP (bleomycin, etoposide, cisplatin). A significant regression of occlusive syndrome with a decline in clinical symptoms was noted. The revaluation at 3 months, 6 months and 1 year were highlighted: A normal clinical examination associated with a persistent correction rate of germline markers and lack of active lesion at thoraco-abdominopelvic CT.展开更多
