[Results of radiotherapy in patients with stage-II Hodgkin's lymphoma with mediastinal lymph node involvement].

Depending on size of intrathoracic lymph nodes, 65 patients with Hodgkin's disease (stage II) were divided into two groups using the mediastinal-thoracic index (MTI): MTI = 0.22-0.3 prior to irradiation and MTI (0.3. Mediastinal nodes showed complete regression immediately after therapy (34-49 Gy aimed at mediastinum) in 12.3% only. In 44 patients (67.6%), complete response was not observed until 3-6 months after treatment, sometimes 24 months. Tumor recurred outside area of exposure 2-4 years in 4 (10.8%) in group I and 2 (7%) in group II (p(3.841). No correlation between recurrence rates and intrathoracic lymph node size was established. 10-year survival in both groups was 89.1 and 92.8%, respectively.
