• W2767245750 abstract "Since December 2013, we initiated a phase II/III trial [Japan Clinical Oncology Group (JCOG) 1201/Thoracic Oncology Research Group (TORG) 1528: UMIN000012605] for elderly patients with extensive-disease small-cell lung cancer (ED-SCLC). Aim of the study is to demonstrate that a carboplatin plus irinotecan regimen is superior to carboplatin plus etoposide in elderly patients with ED-SCLC. However, the patient accrual rate did not satisfactorily match our expectations a year from the time of initiation of our study. To define factors related to low accrual, we searched institutional records and analyzed. We collected data of elderly patients with ED-SCLC from each institution and investigated the total number of elderly patients with ED-SCLC, number of patients eligible/ineligible for the study, numbers of patients registered for the study, and the reasons for non-registration of even eligible patients. Doctor-reported questionnaires concerning elderly (≥71 years old) ED-SCLC patients diagnosed in their institutions were sent to chief or coordinate doctors at each institution in December 2014. We received a response from 32 (84%) of 38 institutions. Approximately 260 patients were diagnosed as elderly patients with ED-SCLC in the last year. Only 100 patients (38%) were eligible for the JCOG 1201/TORG1528 trial. Reasons for ineligibility primarily included poor performance status (PS) (25%), low organ functions (25%), interstitial pneumonitis (19%) and double cancer (18%). Only 23 patients among the 100 eligible candidates accrued to the study. The primary reasons for non-accrual were delayed approval from the Institutional Review Board (IRB) of the individual institution (24%), physician preferences (23%), patient refusal (18%), and registration for other trials (12%). Our data demonstrated that 62% of ED-SCLC patients were ineligible for the protocol due to frailty with the most frequent reason being comorbidities such as poor PS and low organ functions. However, inactive institutions need to increase their efforts to register a greater number of eligible patients in addition to obtaining quicker IRB approval of protocol. Based on responses to questionnaires sent out as part of our investigation, in January 2016, the protocol was revised in terms of eligibility criteria to enhance patient accrual. Eligibility criteria for participation of elderly patients with ED-SCLC need to be formulated prudently so that patients are benefitted in routine clinical practice." @default.
