Purpose: To evaluate the clinicopathologic and oncological outcomes of advanced metastatic testicular cancer in Korean men who underwent retroperitoneal lymph node dissection (RPLND) following chemotherapy.
Materials and Methods: Data of 26 patients with testicular cancer who underwent RPLND after chemotherapy at 2 hospitals in Korea between September 2004 and June 2016 were retrospectively analyzed. Clinical and histopathological variables such as stage of the testicular cancer, age of the patients during surgery, size of the retroperitoneal lymph nodes (RPLNs), histopathological results, duration and complications related to the surgery, cancer recurrence, and mortality were analyzed.
Results: During testicular surgery, the T stage was pT1, pT2, and pT3 in 50% (n=13), 26.9% (n=7), and 15.3% (n=4) of the patients, respectively. Mixed germ cell tumor was the most common finding, seen in 73.1% (n=19) of patients. The indications for RPLND were residual lymph nodes after chemotherapy, 84.6% (n=22); and disease progression and remission, 7.7% (n=2). Pathological analysis revealed viable tumors in 19.2% of patients (n=5), necrotic/fibrotic tissue in 42.3% (n=11), and teratoma in 34.6% (n=9). Intraoperative and postoperative complications occurred in 23.1% (n=6) and 19.2% of patients (n=5). The median duration of follow-up was 27.5 months (interquartile range, 1.3?108.2 months); 11.5% (n=3) patients had recurrence, and 3.8% (n=1) died of progressive metastatic testicular cancer.
Conclusions: Viable germ cell tumors were present in 19.2% of patients with testicular cancer who underwent RPLND after chemotherapy. This is the first study of its kind in the Korean population.
