This study investigated the effects of extending the interval of R-CHOP therapy on the prognoses of patients with non-indolent non-Hodgkin's B-cell lymphoma. The results showed that patients with intervals of >= 4 weeks were older, had longer follow-up periods and lower relative dose intensity. However, there was no significant difference in the 3-year overall survival rate compared to patients with intervals < 4 weeks.
R-CHOP therapy is generally performed every 3 weeks. We investigated the effects of extending the interval of R-CHOP therapy for > 1 week on the prognoses of patients with non-indolent non-Hodgkin's B-cell lymphoma. Among the 338 patients with non-indolent non-Hodgkin's B-cell lymphoma who received initial chemotherapy at our institution, we focused on 178 patients who received R-CHOP therapy and analyzed the outcomes of the patients stratified by the treatment intervals. The estimated 3-year overall survival (OS) for the entire population was 82.1%. Patients treated at intervals of >= 4 weeks were significantly older, and they had significantly longer follow-up periods and lower relative dose intensity. But the estimated 3-year OS was comparable to those treated at < 4 weeks (83.3% vs. 80.5% p=0.947). In a multivariate analysis, age and the dose of anti-cancer agents had significant impacts on OS, but there was no significant relationship regarding the treatment intervals. Propensity score matching confirmed the same result. R-CHOP therapy every around 4 weeks could achieve relatively good survival in some selected patients with non-indolent non-Hodgkin's B-cell lymphoma.
