Objective The objective of the study is to investigate depressive symptoms before and after the initiation of chemotherapy and their impact on overall survival (OS) among patients with hematological malignancies. Methods We performed a prospective analysis of consecutive patients with newly diagnosed malignant lymphoma or multiple myeloma enrolled between September 2010 and March 2016. We evaluated depression symptoms at two time points: before starting chemotherapy (T1) and 1 month later (T2), using PHQ‐9 and known prognostic factors. We allocated participants with depressive symptoms at T1 and/or T2 to a depression group that was subdivided as follows: new depressive symptoms at T2, (“new‐onset”), remission of depressive symptoms at T2 (“remission”), and persistent depressive symptoms from T1 to T2 (“persistent”). The main outcome, OS, was evaluated using Kaplan‐Meier methods and multivariate Cox proportional hazards modeling. Results Of the 294 eligible participants, we analyzed 255 patients, including 83 with depression. There were 19 participants in the new‐onset, 38 in the remission, and 26 in the persistent depression group. The OS of participants with depression was significantly shorter than that of those without depression (adjusted hazard ratio [AjHR] 2.43; 95% confidence interval [CI] 1.43‐4.12; P < .001). Using the never‐depressive symptoms group as a reference group, AjHRs were as follows: new‐onset, 1.91 (95% CI, 0.77‐4.75; 0.166); remission, 2.98 (95% CI, 1.55‐5.74; 0.001), and persistent, 2.17 (95%CI, 1.01‐4.68; 0.047). Conclusions Among patients with mature lymphoid malignancy, the group with depression at baseline had a poorer survival, both in the group that remained depressive and the group that recovered from depressive symptoms.
