Non-Hodgkin's lymphomas (NHL) are malignant tumors that develop from lymphoid tissue. They are one of the most common malignancies and they represent one of the most complicated problems of oncohematology. The age group that is mostly affected by NHL in the Republic of Moldova is the patients over 60 years, and the disorder in most cases starts in lymph nodes. This study aims to determine the particularities of elderly patients with NHL with primary involvement of peripheral lymph nodes(l/n).

A retrospective study of a group of 78 NHL patients with primary lymph node involvement was performed. The average age of study participants ranged from 60 to 84 years.

NHL more often developed primarily in the peripheral l/n (84.7%), less frequently in the mediastinal l/n (6.4%) and abdominal l/n(8.9%). Aggressive NHL predominated (59.0%), but indolent NHL also developed quite frequently (41.0%), which were more frequent in cases of primary affection to the cervical l/n (47.4%), inguinal l/n(41.7%), and abdominal l/n(42.9%). The 5-year survival of NHL patients with primary lymph node involvement aged over 60 years was low and amounted to 31.2%;

NHL occurred more often in the peripheral lymph nodes (84.7%), less frequently in the mediastinum (6.4%), and abdominal lymph nodes (8.9%). The frequency of aggressive NHL was 59.0%. Indolent NHL was diagnosed in 41% of cases. The 5-year survival rate in the study group constitutes 31,2%, lower compared with younger patients treated in the same center.
