@entity1 @entity978
A total of 234 @entity1 of @entity978 treated at 7 institutions from 1972 through 1985 were analyzed. Male to female ratio was 157: 77, mean age was 39.8 years, and overall 5- and 10-year survival were 67% and 56%, respectively. Of 126 @entity1 treated by radiotherapy with more than 36 Gy, alone or preceded to other treatments, 5- and 10-year survival rates were 84% and 80% for Stage I (43 @entity1 ), 79% and 69% for Stage II (71 pts.), and 52% and none for Stage III (12 pts.), respectively. Survival rate was better for LP, NS and MC histologies as compared to LD, better for @entity1 without constitutional symptoms, as compared to @entity1 with B, and better for @entity1 with ages younger than 59 years as compared to those with ages over 60 years. Relapse was observed in 57 out of 126 @entity1 . Relapse within the irradiation field was observed in only 4, and nodal areas outside the field, especially of abdomen (1/3), were the most common sites. Half of the relapses occurred within 20 months, and 80%, 40 months. Five-year survival of @entity1 after relapse to lower torso lymph nodes (19 @entity1 ) was 37%, which was worse than @entity1 after relapse to upper torso lymph nodes (15 @entity1 : 63%) (z = 1.507, N.S.).
