Late recurrence of testicular cancer.

The aim of this study is to draw attention to important points concerning the clinical management of late relapses in testicular cancer. From 1972 to 1982 The Norwegian Radium Hospital (NRH) has treated 1,008 patients with testicular cancer. Fifteen (1.5%) of these patients relapsed 36 months or more after their primary treatment. The patients' medical records were reviewed in this retrospective study, and all available histological sections were reevaluated. Six patients had pure seminoma initially and relapsed after an average of 54.5 months. Five of them had subjective symptoms due to recurrent tumor. Four patients relapsing in the supradiaphragmatic lymph nodes only are alive with no evidence of disease after an observation time of 17 to 30 months after treatment. Nine nonseminoma patients relapsed after an average of 85 months (36 to 194 months). Eight of these were aware of subjective signs or symptoms due to recurrent tumor leading to the diagnosis of the relapse. Four of these patients are alive with no evidence of disease after an observation time of 4 to 46 months after treatment. Two of these patients relapsed with pure mature teratoma. Late relapses do occur although they are rare events. Seminoma patients relapsing in the lymph nodes only have a good prognosis, and nonseminoma patients have a slightly poorer prognosis. Active follow-up for relapse detection is not justified. All testicular cancer patients should instead be informed of typical signs and symptoms that can be related to a relapse and encouraged to seek medical help for further investigation.
