SummaryAn observational population-based cohort study was performed to investigate the role of comorbidity on outcome and treatment-related toxicity in patients with newly diagnosed advanced-stage diffuse large B-cell lymphoma (DLBCL) treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). Data for the clinical characteristics of 154 patients (median age 69 years), including Charlson Comorbidity Index (CCI), treatment, toxicity and outcome were evaluated. Forty-five percent of the patients had an International Prognistic index ≥3 and 16% had a CCI ≥2. The planned R-CHOP schedule was completed by 84% and 75% reached complete remission (CR). In those with CCI ≥2, 67% completed treatment with 46% CR. In patients with a CCI <2, overall survival (OS) after 1, 2 and 5 years was 84%, 79% and 65% respectively and it was 64%, 48% and 48% for those with CCI ≥2. Grade III/IV toxicity was documented in 53%, most frequently febrile neutropenia (27%) and infections (23%). In multivariate analysis CCI ≥2 and IPI ≥3 were independent risk indicators for OS and grade III/IV toxicity. In conclusion, comorbidity is an independent risk indicator for worse OS in patients with advanced DLBCL treated with R-CHOP by interference with intensive treatment schedules and more grade III/IV toxicity. Future studies are warranted to determine the optimal treatment approach in patients with significant comorbidities.
To assess treatment strategies, toxicity and outcome in very elderly patients (aged ≥ 75 years) diagnosed with diffuse large B-cell lymphoma (DLBCL) in the rituximab era, an observational population-based cohort study was performed. From 103 patients with a median age of 81 years, data of clinical characteristics, treatment, toxicity and outcome were evaluated. Advanced stage DLBCL was documented in 74 patients. In 80 patients chemotherapy was initiated; 70 patients received rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP). In this group, 39 patients completed all cycles and 30 patients achieved a complete remission. Severe chemotherapy-related toxicity occurred in 69%. Two-year overall survival was 70% for elderly patients who completed chemotherapy, 28% for those treated with incomplete or suboptimal chemotherapy and 21% for those receiving palliative radiotherapy or supportive care. In conclusion, the ability to complete R-CHOP was associated with better overall survival compared to other treatment strategies at the expense of severe treatment-related toxicity.
The expression of p53 and alpha-B-crystallin were related to the differentiation and site of the HNSCC. Alpha-B-crystallin was not a prognostic marker for HNSCC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
