ABSTRACT
The peripheral T-cell lymphomas (PTCL) are rare and heterogeneous diseases characterized by an unfavorable prognosis. Chemotherapy is standard upfront treatment in most patients, but responses are short-lived with few FDA-approved "novel" agents available. We sought to define the impact of these novel agents as single agents or in clinical trials on the outcomes of patients with PTCL. From January 1994 to May 2019, adult patients with PTCL who were managed at our institution were included in this analysis. In addition to patients with incomplete data, those diagnosed with large granular lymphocytic leukemia and cutaneous T-cell lymphoma (CTCL) except for transformed mycosis fungoides were excluded. Statistical analyses were performed using SAS version 9.4. There were 219 patients included in the analysis. The median age at diagnosis was 56 years (range, 18-90 years). First line therapies mostly consisted of combination chemotherapy (75%). There was a statistical difference among patients who received chemotherapy, novel agents alone and in chemotherapy-free combinations, other, and no treatment (P < .0001). In patients who were treated with second line chemotherapy, novel agents alone and in combination without chemotherapy, or other, there was a still a survival benefit favoring novel agents (P = .0417). In the third line, there was no statistical difference among the three groups (P = .569). All patients who received novel therapies and underwent autologous stem cell transplant (autoSCT) achieved a complete response (CR) and had a better survival compared with patients who underwent chemotherapy who had a 70% CR rate prior to autoSCT (P = .046). Exposure to FDA-approved novel agents, immunoepigenetic trials, and clinical trials in general was associated with an overall survival (OS) benefit (P = .003, P = .04, and P = .006, respectively). These data suggest that patients who receive novel agents have superior outcomes compared with patients without exposure to novel therapies who receive chemotherapy-predicated treatments.
