title: Management of seminoma with bulky abdominal disease.
abstract: Thirty-three cases of seminoma with palpable abdominal disease were treated at the Cancer Control Agency of B.C. between 1948 and 1983. Twenty-three had disease confined to the abdomen (Stage IIB), eight had simultaneous involvement of mediastinal and supraclavicular nodes (Stage IIIB) and two had bone or pulmonary metastases (Stage IV). Five and 10-year disease-specific actuarial survivals for the whole group were 87% and 81%, respectively. Corresponding relapse-free survival was 64%. Of the twenty-three IIB cases, 15 had primary treatment with abdominal radiation only, and eight had prophylactic mediastinal/supraclavicular radiation. Although relapse in IIB was more common in the group receiving abdominal radiation only, survival was unchanged. For the entire IIB group, 5- and 10-year disease-specific actuarial survivals were 91% and 84%, respectively, and corresponding relapse-free survival was 74%. The eight IIIB patients were treated primarily with radiation. Four patients relapsed, all in extranodal sites. Two of these died of disease. Both Stage IV patients required radiation and chemotherapy for long-term disease control. Stage IIB disease can be treated primarily with abdominal radiation, but radiation alone is inadequate when bulky abdominal disease is associated with supradiaphragmatic lymphatic spread or hematogenous metastases.
