PurposeNational Cancer Institute of Canada Clinical Trials Group Study BR.21 established erlotinib as a standard of care in patients with non–small-cell lung cancer (NSCLC) after failure of first- or second-line chemotherapy. The current study analyzes the influence of age on outcomes in BR.21.Patients and MethodsBR.21 was a double-blind phase III trial that randomly assigned 731 patients to erlotinib 150 mg daily or placebo. End points included progression-free survival and overall survival (OS), response, quality of life (QOL), drug exposure, and toxicity, which are analyzed in this retrospective study by the following two age groups: ≥ 70 years (elderly) or less than 70 years (young).ResultsThere were 163 elderly patients (112 on erlotinib, 51 on placebo) and 568 young patients (376 on erlotinib, 192 on placebo). There was no significant difference between age groups randomly assigned to erlotinib or placebo in progression-free survival (elderly: 3.0 v 2.1 months; hazard ratio [HR] = 0.63; 95% CI, 0.44 to 0.90; P = .009; young: 2.1 v 1.8 months; HR = 0.64; 95% CI, 0.53 to 0.76; P < .0001; interaction, P = .77) or OS (elderly: 7.6 v 5.0 months; HR = 0.92; 95% CI, 0.64 to 1.34; P = .67; young: 6.4 v 4.7 months; HR = 0.73; 95% CI, 0.61 to 0.89; P = .0014; interaction, P = .31). Response rates were similar between age groups. Elderly patients, compared with young patients, had significantly more overall and severe (grade 3 and 4) toxicity (35% v 18%; P < .001), were more likely to discontinue treatment as a result of treatment-related toxicity (12% v 3%; P < .0001), and had lower relative dose-intensity (64% v 82% received > 90% planned dose; P < .001).ConclusionElderly patients treated with erlotinib gain similar survival and QOL benefits as younger patients but experience greater toxicity.

Purpose Docetaxel has shown activity in elderly patients with advanced non–small-cell lung cancer (NSCLC). This randomized phase III trial evaluated the efficacy and safety of docetaxel versus vinorelbine (the current standard treatment) in elderly patients. Patients and Methods Chemotherapy-naïve patients age 70 years or older with stage IIIB/IV NSCLC and performance status 2 or lower were eligible. Patients randomly received docetaxel 60 mg/m2 (day 1) or vinorelbine 25 mg/m2 (days 1 and 8) every 21 days for four cycles. The primary end point was overall survival. Overall disease-related symptom improvement was assessed using an eight-item questionnaire. Results In total, 182 patients were enrolled. Median age was 76 years (range, 70 years to 86 years). There was no statistical difference in median overall survival with docetaxel versus vinorelbine (14.3 months v 9.9 months; hazard ratio, 0.780; 95% CI, 0.561 to 1.085; P = .138). There was a significant difference in median progression-free survival (5.5 months v 3.1 months; P < .001). Response rates were also significantly improved with docetaxel versus vinorelbine (22.7% v 9.9%; P = .019). The most common grade 3 to 4 toxicities were neutropenia (82.9% for docetaxel; 69.2% for vinorelbine; P = .031) and leukopenia (58.0% for docetaxel; 51.7% for vinorelbine). Other toxicities were mild and generally well tolerated. Docetaxel improved overall disease-related symptoms over vinorelbine (odds ratio, 1.86; 95% CI, 1.09 to 3.20). Conclusion Docetaxel improved progression-free survival, response rate, and disease-related symptoms versus vinorelbine. Overall survival was not statistically significantly improved at this time. Docetaxel monotherapy may be considered as an option in the standard treatment of elderly patients with advanced NSCLC.

9541 Background: Previous studies have suggested that tumor growth rate (g), estimated using prostate-specific antigen values, is associated with overall survival (OS) in prostate cancer (Wilkerson, 2016). We performed a retrospective pooled analysis in non-small cell lung cancer (NSCLC) to investigate the extent to which g values estimated using radiological tumor measurements in clinical trials are associated with survival. Methods: We identified 24 randomized clinical trials submitted to FDA between 2013 and 2019 investigating either immune checkpoint inhibitor (ICI) or targeted therapy (TT) in pts with metastatic NSCLC. Of 9934 patients (pts) enrolled, 5532 pts (2401, 1189, and 1942 pts treated with ICI, TT, and chemotherapy respectively) had sufficient data to derive a valid g. The g was evaluated by both type and line of therapy. Pts were then grouped according to quartiles of g, with Q1 being the lowest. We calculated OS and progression-free survival (PFS) for each group via the Kaplan-Meier method, and used the Cox model for group comparison. Results: Median g was 9.7E-4, 1.4E-3, and 2.2E-3/day, and median OS was 34.2, 21.3, and 15.3 months (mo), in pts treated with TT, ICI, and chemotherapy, respectively, regardless of lines of therapy. When treated with the same type of therapy, pts receiving 2nd line therapy had a higher median g than those receiving 1st line. The median survival and log-rank hazard ratios for pts treated with 1st line ICI monotherapy are shown in the Table. Conclusions: TT is associated with the lowest median g, followed by ICI, and then chemotherapy, perhaps due to patient selection, better inherent biology/natural history, or favorable results of TT on selected tumors. Regardless, we found that g is inversely associated with survival, across treatment types. This relationship is also observed in pts treated with the same type and line of therapy (for example, 1st line ICI), where Q1 has the longest survival, followed by Q2, Q3, and then Q4. In summary, our exploratory analysis suggests that g derived from radiological tumor measurements in NSCLC may relate to survival. Prospective studies are needed to evaluate if g might be an earlier endpoint compared to classical response criteria. [Table: see text]

Aim: This study aimed to investigate the prognostic value of peripheral naive and memory CD8+ and CD4+ T cells and other immune cells in patients with oligometastatic non-small-cell lung cancer (NSCLC) undergoing radiotherapy (RT). Methods: A total of 142 patients with oligometastatic NSCLC treated with RT were enrolled, and their blood samples were collected within 3 days before RT. Immune cells were identified by flow cytometry. Results: Patients with high levels of naive CD8+ T cells had longer overall survival (p = 0.004) and progression-free survival (p = 0.001) than those with low levels of naive CD8+ T cells. Multivariate analyses revealed that naive CD8+ T cells were independently correlated with overall survival (p = 0.019) and progression-free survival (p = 0.024). Conclusion: The results suggest that peripheral naive CD8+ T cells may be an independent prognostic indicator for patients with oligometastatic NSCLC undergoing RT.
