RESUMO

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.

RESUMO

OBJECTIVES: Late relapses (>2 years) after completion of chemotherapy are rare and often platinum-resistant. There are limited data concerning late relapses in chemotherapy-naïve patients with stage I germ cell tumors. This retrospective analysis was performed to compare the outcome between patients with stage I germ cell tumors, who had late (≥2 years) and early (≥3 months and <2 years) relapse after orchiectomy. METHODS AND MATERIALS: We analyzed data of 1,069 chemotherapy-naïve patients with advanced germ cell tumors of testis treated in our department from 1986 to 2008. All patients had cisplatin- and etoposide-based chemotherapy. We identified 169 (15.8%) patients with prior stage I disease, who had not received adjuvant treatment: 140 and 29 patients had early and late relapse, respectively. Among patients with late relapse, pure seminoma was revealed in 14 patients, and nonseminoma in 15 patients. Median follow-up time for 169 patients was 35 (range, 2-218) months. RESULTS: Patients with late relapse were older, 35 years (23-57) and had more frequent pure seminoma in primary tumor, 14/29 (48.3%), than patients with early relapse, 30 years (16-63) (P = 0.0008) and 46/140 (32,8%, P = 0.08), respectively. At the time of disease progression, both groups were very similar according to well-known prognostic factors including IGCCCG classification. The only difference was larger size of retroperitoneal lymph nodes in late (9 cm) than in early relapse (4 cm, P < 0.0001). The outcome in patients with late relapse was significantly worse than in patients with early relapse: complete response rate after induction chemotherapy was 20.7% (6/29) vs. 42.1% (59/140) (P = 0.01), 3-year progression-free survival 66% vs. 84% (P = 0.02, HR = 2.4, 95% CI 1.2-8.8) and 3-year overall survival, 72% vs. 88% (P = 0.04, HR = 2.4, 95% CI 1.05-10.25), respectively. In patients with pure seminoma, this difference in overall survival was even more significant: 65% vs. 91% (P = 0.04, HR = 3.8, 95% CI 1.06-32.4). CONCLUSIONS: Late relapses following stage I germ cell tumors were associated with seminoma, older age, and worse outcome after induction chemotherapy.
