title: Retroperitoneal lymph node dissection in clinical stage IIA and IIB nonseminomatous germ cell tumours of the testis.
abstract: From 1980 to 1984 inclusive, ninety-one consecutive evaluable patients underwent primary retroperitoneal lymphadenectomy for clinical stage IIA or IIB nonseminomatous germinal testicular cancer. Nodes were negative in twenty cases (22%), and forty-seven patients (52%) were treated with chemotherapy either postoperatively (thirty clinically understaged patients) or at relapse (seventeen cases). After a median follow-up period of nearly 5 years (range 18-78 months) the disease-free survival was 98%. None of thirty patients with radiographic abnormalities greater than or equal to 3 cm in the retroperitoneal nodes had negative histology, and twenty-two (73%) were treated with chemotherapy. Preoperative serum levels of AFP and hCG were not useful in selecting patients with positive nodes. Primary chemotherapy is now used in patients with radiographic evidence of retroperitoneal metastases greater than or equal to 3 cm.
