With an aim to analyze and document the outcome of Stage I Seminoma patients we undertook a retrospective analysis of patients treated between January 1990 and December 1998. The treatment charts of patients treated between January 1990 and December 1998 were reviewed. Patient and tumor characteristics, treatment details, relapse rates, late toxicities, or occurrence of second primary was noted. Royal Marsden Staging System was utilized because of its simplicity and wide-use in the above

... Out of 137 patients, 41 (30%) patients did not receive any further treatment, 96 (70%) patients received prophylactic radiotherapy to para-aortic and pelvic nodes. The observation group patients had a median follow-up 20 months, 9 patients had nodal relapse with 7 in retroperitoneal nodes and 2 patients in inguinal nodes. Of these, 7 patients received BEP chemotherapy and 2 patients Chemoradiation. Four patients had complete remission while remaining 5 patients had partial response. The histopathologies of all the 5 patients with partial response were reviewed to reconfirm the diagnosis. Patients of prophylactic radiotherapy group had a follow-up of 33 months, 6 patients relapsed, RP nodal disease in 5 patients and distant metastasis in 1 patient. All these patients received BEP chemotherapy. One had complete response and remaining 5 patients had partial response. The group of patients under observation had a significantly higher relapse rate and lower disease free compared to the adjuvant radiotherapy group (73.5% vs. 91% at five years, p value 0.004). Disease specific survivals for the two groups were however similar (89% vs. 93%) at five years, p value 0.18). We conclude that Stage I Seminoma patients treated with prophylactic radiation to paraaortic and pelvic region had better outcome.
