EHPnet: Collaborative on Health and the Environment Toxicant and Disease Database

Suiamry Twenty-four out of 164 (14%) adult patients with pnrmary germ cell tumours of testis seen over the last 6 years at the Institute Rotary Cancer Hospital (IRCH) of the All India Institute of Medical Sciences (AIIMS), New Delhi, were found to have cryptorchidism. Only one patient had undergone correction. As a result the testes were intra-abdominal in the vast majority, and patients presented late. Twenty-two patients presented with stage Ilb or more advanced disease. Twelve patients had seminoma and the others had mixed or non-seminomatous germ cell tumour (NSGCT), i.e. 50% each. The earlier patients were managed by initial resection followed by radiation and or chemotherapy. As experience grew the seven patients who presented late were given initial chemotherapy followed by resection in those with residual tumours. The probability of overall survival was 0.65 at 36 months and, was not significantly different from survival in 114 patients with tumours of normally descended testis. Early orchipexy facilitates the detection, but whether it reduces the incidence of tumours is controversial. Uncorrected cryptorchidism is now rarely seen in the West, but in India and many other developing countries tumours of uncorrected cryptorchid testes continue to be seen.
