Spontaneous regression of metastases from testicular tumours. A report of six cases from one centre.

In a review of the cases of testicular tumours treated at the Christie Hospital between 1961 and 1974 there are six cases with spontaneous regression of metastases, which are now reported. In this period, 827 cases of testicular tumour have been treated giving an incidence of spontaneous regression of 0.72%, which is considerably higher than previously reported. One of the cases appears to be pure seminoma; spontaneous regression of metastases from seminoma has not been reported previously.
