Durvalumab: a potential maintenance therapy in surgery-ineligible non-small-cell lung cancer.

ABSTRACT: Lung cancer is the most common cancer worldwide and the most common cause of cancer-related death. Non-small-cell lung cancer comprises ~87% of newly diagnosed cases of lung cancer, and nearly one-third of these patients have stage III disease. Despite improvements in the treatment of stage IV lung cancer, particularly with the introduction and dissemination of checkpoint inhibitors, very little progress has been made in the treatment of stage III lung cancer. In this article, we discuss the general staging criteria and treatment options for stage III lung cancer. We review how concurrent radiation and chemotherapy can have immunomodulatory effects, supporting the rationale for incorporating immunotherapy into existing treatment paradigms. Finally, we discuss the results of the PACIFIC trial and implications for the treatment of stage III lung cancer. In the PACIFIC trial, adding durvalumab as a maintenance therapy following the completion of chemoradiotherapy improved progression-free survival in patients with locally advanced unresectable stage III lung cancer. On the strength of these results, durvalumab has been approved by the US Food and Drug Administration for use in this setting, representing the first advance in the treatment of stage III lung cancer in nearly a decade.

Project description:Background:Durvalumab as maintenance treatment after platinum-based concurrent chemoradiotherapy (cCRT) has become the standard of care in inoperable stage III non-small cell lung cancer (NSCLC). In this nationwide survey, we solicited members of the German Radiation Oncology Society to review the current distribution and clinical settings of durvalumab treatment after cCRT, observed side effects and summarize follow-up management. Methods:We surveyed radiation oncology institutions in Germany via an anonymous online questionnaire sent by e-mail to all members of the German Radiation Oncology Society which agreed their willingness to participate. Results:We received a total of 255 responses (response rate: 18%). Of which 203 (80%) were completed and returned and thus eligible for further evaluation. The respondents work in 87 different cities and 44% in a private medical practice, 29% in university and 22% in a general hospital. Durvalumab was implemented in clinical routine by 70% of respondents. Major reasons for failed implementation in clinical practice reported by the respondents were patient's ineligibility (42%), lack of required PD-L1 status (25%), decision of medical oncologists (7%) or absence of updated German guidelines (7%). Thirty-six percent of all respondents report low (?30%) PD-L1 testing before cCRT based on IHC assay. No respondent had applied durvalumab in less than 14 days after the completion of CRT. Severe side effects requiring hospital admission in more than 10% of all patients were reported by 12% of all respondents. Conclusions:Durvalumab maintenance is already implemented in the radiation oncology community and administered by the absolute majority of respondents. Low testing rates of PD-L1 at initial diagnosis were observed and should be considered a major barrier to universal adoption and integration in the clinical work-flow in countries with durvalumab approval restricted to PD-L1 positive patients. No respondent applies durvalumab in less than 14 days after cCRT.
