Delayed Orchiectomy at Postchemotherapy Retroperitoneal Lymph Node Dissection Due to Laterality of Retroperitoneal Metastatic Pattern Consistent with Testicular Primary: Assessment of Pathologic Findings

Management of Primary Testicular Tumor

In any man with a solid testicular mass, cancer should be considered until proven otherwise. Radical inguinal orchiectomy is the treatment of choice in patients with testis mass. Placement of a testicular prosthesis is safe with a very low complication rate and should be offered to all patients undergoing radical orchiectomy. In patients with widespread or life-threatening advanced disease, delayed orchiectomy following chemotherapy is recommended. Testis-sparing surgery can be performed in highly selected patients with solitary testicle mass, bilateral testicular tumors, or strong suspicion of a benign lesion.

Effect of the timing of orchiectomy on survival in patients with metastatic germ cell tumors of testis

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.
