Abstract :Aim: To investigate factors associated with response to treatment in non-Hodgkin lymphoma insert ignore into journalissuearticles values(NHL); patients receiving chemoinsert ignore into journalissuearticles values(radio);therapy, and secondarily, to identify parameters influencing mortality. Methods: This was a retrospective single center study carried out between January 2013 and December 2022. A total of 245 patients newly diagnosed with NHL who were treated in our department were included. Clinicodemographic features, NHL characteristics, treatments and follow-up data were retrieved from the hospital database and charts. Patients were grouped as responders insert ignore into journalissuearticles values(RT); and non-responders insert ignore into journalissuearticles values(NRT); to treatment, as well as deceased insert ignore into journalissuearticles values(DP); and survivors insert ignore into journalissuearticles values(SP);. Factors associated with response to treatment and mortality were determined by univariate and multivariable analysis. Results: Age was similar in the RT insert ignore into journalissuearticles values(56.2 ± 14.5); and NRT insert ignore into journalissuearticles values(59.5 ± 13.7); groups; however, male sex was significantly more frequent in the RT group insert ignore into journalissuearticles values(58.1% vs. 35.71%; p = 0.042);. Multiple logistic regression revealed that female sex, low performance status, frailty, high lymphocyte level, extranodal involvement, mantle cell lymphoma, thrombocytopenia during treatment, and cardiac complications during treatment were independently associated with no response to treatment. With respect to groups based on mortality, the DP group was significantly younger compared to the SP group insert ignore into journalissuearticles values(50.8 ± 11.7 vs. 57.1 ± 14.6; p = 0.048);, while sex distribution was similar insert ignore into journalissuearticles values(males comprised 54.7% of the DP and 63.6% of SP group);. Multiple regression showed that extranodal involvement, thrombosis during treatment, and secondary malignancy were independently associated with mortality. Conclusion: Considering these characteristics when making treatment decisions and throughout the follow-up period may improve survival and reduce mortality in NHL.
