Delayed Orchiectomy at Postchemotherapy Retroperitoneal Lymph Node Dissection Due to Laterality of Retroperitoneal Metastatic Pattern Consistent With Testicular Primary: Assessment of Pathologic Findings
ABSTRACT It has been estimated that extragonadal germ cell tumors (EGCTs) constitute 3% to 5% of germ cell neoplasms. An interesting clinical scenario occurs when a patient with a presumed EGCT and normal testicular examination and ultrasound findings has a retroperitoneal metastatic pattern consistent with either a right or left-sided testicular primary. We reviewed the pathologic data of patients presenting with these clinical findings after delayed orchiectomy at postchemotherapy retroperitoneal lymph node dissection (PC-RPLND).
We identified 14 patients with apparent EGCT who had undergone simultaneous orchiectomy at PC-RPLND at our institution from July 1979 to July 2002 because of a lateralizing pattern of retroperitoneal metastases concerning for a testicular primary. Of the 14 patients, 3 had completely normal testicular ultrasound findings after chemotherapy and 11 had minimal ultrasound findings not consistent with a testicular tumor.
Two (14%) of the PC orchiectomy specimens contained mature teratoma and eight (57%) contained necrosis and/or focal fibrosis. Thus, 10 (71%) of 14 patients undergoing PC orchiectomy at PC-RPLND because of metastatic disease laterality had evidence of a testicular primary.
Most (71%) patients with a presumed EGCT who underwent PC orchiectomy because of lateralizing retroperitoneal metastases had histologic evidence of a testicular primary (20% teratoma, 80% focal necrosis or fibrosis). If the retroperitoneal pattern of metastatic tumor spread is consistent with a primary testicular tumor, we offer PC orchiectomy to patients with apparent EGCT at PC-RPLND, even if the PC testicular examination and ultrasound findings are normal.

ABSTRACT: Objectives: Classically, orchiectomy (OE) is the first step of treatment in patients with metastatic germ cell tumors (mGCTs) of testis. However, some patients have severe symptoms of disease, which require immediate beginning of chemotherapy (CT) followed by OE. This retrospective analysis was performed to find the effect of time constraints of delayed OE on survival in patients with mGCT. Methods and materials: We analyzed the data of 1,483 CT-naive patients with advanced mGCT of the testis treated in our Department from 1986 to 2009. Delayed OE was performed on 71 (4.8%) patients: seminoma in 8 patients (11.2%), nonseminomatous tumor in 50 patients (70.4%), and unknown tumor histology in 13 patients (18.4%). Twenty percent, 40%, and 40% of patients belonged to good, intermediate, and poor International Germ Cell Cancer Consensus Group prognostic groups, respectively. Median time from the beginning of the CT to OE was 18 (range, 1-250) days. OE was performed on 39 (55%), 21 (29.5%), and 11 (15.5%) patients during cycle 1, cycle 2 to completion of CT, and after the finishing of induction CT, respectively. Median follow-up time was 156 (range, 3-241) months. Etoposide and cisplatin-based CTs were received by 66 patients (93%). Results: Three-year overall survival (OS) of all 1,483 patients was 75%. An excellent primary tumor response to CT was observed among the patients, who had delayed OE after completion of CT (n = 11): only mature teratoma (n = 4) and tumor necrosis (n = 7) were found. The 3-year OS in patients with delayed OE was 63%. OE performed after completion of CT was associated with better prognosis. The 3-year OS in patients with delayed OE performed during the cycle 1 (group 1) was 67%, cycle 2 to completion of CT (group 2) was 39%, and after finishing of CT (group 3) was 88% (groups 1 vs. 3: hazard ratio 3.7, 95% confidence interval 0.69-10.1, P = 0.15; groups 2 vs. 3: P = 0.01, hazard ratio 8.1, 95% confidence interval 1.32-18.,72). It seems that if OE had been performed during CT, the beginning of the successive cycle was delayed and dose intensity of CT was decreased. Conclusions: In case of severe symptoms of disease, which require an immediate start of CT, performing OE simultaneously with other surgeries after completion of induction CT was associated with better OS, when compared with performing OE during induction CT.Urologic Oncology 04/2013; 32(1).
