[Primary forms of extralymphatic non-Hodgkin's lymphoma].

In 1981-1990, 584 patients with non-Hodgkin malignant lymphoma, 209 women and 375 men, aged between 17 and 75 years, were treated at the I Department of Medicine and Department of Hematology, Silesian Medical Academy in Katowice. In this group the primary localization outside lymph nodes was seen in 26 patients (9 women and 17 men), i.e. 4.6% of all patients with malignant non-Hodgkin lymphomas. Most frequently digestive tract was involved-19 patients (73.1%). Twenty three patients were treated surgically followed by chemotherapy and/or irradiation. Not operated patients were treated with either chemotherapy or both radio- and chemotherapy. Complete remission was achieved in 17 patients (65.4%), partial remission in 4 (15.4%) patients. Five patients did not respond to therapy (19.2%). A mean survival time was 49.4, 14.3, and 6.4 months, respectively.
