[Evaluation of the method of treating non-Hodgkin's lymphoma].

Forty-two patients with non-Hodgkin's lymphoma were treated between October 1983 and December 1992 in the department of Otolaryngology, Kagawa Medical School Hospital. The twenty-six of these patients whose tumor originated in Waldeyer's ring and who were diagnosed as Stage I or II have been reviewed. In principle, method of treatment was a combination of chemotherapy and radiotherapy. Between 1983 to 1987, COP was primarily used (9 cases) as combination chemotherapy, and after 1988 CHOP was used (17 cases). VAMA was used to treat the poor response and recurring cases. The five-year estimated overall survival rates calculated by the Kaplan-Meier method were 33.3% and 94.1% in the COP and CHOP groups, respectively. We investigated age, stage, cell type and grade, as factors related to recovery, but except for cell type, there were no significant differences in overall survival. The most serious side effect was decreased leucocyte count, but we prescribed G-CSF and were able to continue treatment.
