      While many thousands of patients per year receive chemotherapy for advanced NSCLC with first-line or subsequent chemotherapy, little is known about patients’ views on their decision to receive that treatment. In that median survival results generally do not exceed one year, there are many potential risks for regret. Given the highly symptomatic nature of NSCLC coupled with patient, family and oncologist desires to decide rapidly on treatment, many challenges exist affecting quality decision making for patients and their supporters facing treatment. Among 59 studies dealing with regret in a recent systematic review (Becerra Perez 2016), none analyzed patients with lung cancer (66% of studies were in oncology). A clinical profile of the extent of regret, and factors contributing to that regret is lacking in those undergoing chemotherapy for lung cancer.

      All patients were entered into a phase III, two-arm, prospective, randomized trial in patients receiving chemotherapy for lung cancer. Patients were randomly assigned to either usual care (UC), or enhanced care (EC) using the DecisionKEYS decision aid coupled with every 3 week PRO assessment using the electronic LCSS measure. All patients were offered the Decision Regret Scale (“DRS,” O’Connor 1999), at 11 weeks (+/- 2 weeks) after starting treatment. The DRS is a categorical scale with 5-items in 5 categories (ranging from “strongly disagree” to “strongly agree”). Patients completed assessment for decisional conflict; the patients’ supporters completed similar measures.

      164 patients were entered, 160 received chemotherapy. Characteristics: 43% women; 92% Stage IV; 73% first-line therapy. Means: age 63; KPS 81. ECOG 1 = 56%; ECOG 2 = 42%. 46% represented minority groups. 22 different chemotherapy regimens were used. First-line patients received combination regimens with the majority being platinum-based with 2 or 3 drugs. 128 patients (80%) completed the DRS. Results combined the two top categories indicating the greatest extent of regret. Only 9 patients (7%) expressed regret as the maximum of the 5 DRS questions. 94% expressed that the decision for chemotherapy was a wise one. This low degree of regret did not differ by first-line or subsequent chemo or by EC versus UC groups.

      Patients receiving chemotherapy for advanced NSCLC, at 3 months after starting treatment, rarely (7%) have regret, and 98% expressed that they made the right decision. Other factors associated with the few patients with regret, such as decisional conflict or reduced quality of life, will also be presented. Support: NIH/NCI R01 CA-157409
