RESUMO

BACKGROUND: The aim of this study was to determine whether mRNA expressions and dynamic changes of immune-related genes before and after starting first-line treatment with the PD-1 inhibitor pembrolizumab in patients with NSCLC were of predictive value. METHODS: CD3, CD8, PD-1, PD-L1 and CTLA-4 mRNA expression levels were measured from peripheral blood before and after three weeks of treatment with the PD-1 inhibitor. Univariate and multivariate analyses were performed retrospectively. Response, progression-free survival (PFS) and overall survival (OS) were determined. RESULTS: In univariate analysis an increase of CD3 and CD8 mRNA expression after the first cycle of pembrolizumab were each associated with improved PFS and OS. In contrast, patients with no change or with a decrease in CD3 and CD8 mRNA expression showed significantly worse outcome. CD8 mRNA increase remained an independent predictive factor for PFS and OS in the multivariate analysis with p values of 0.011 and 0.006, respectively. CONCLUSIONS: An increase of CD8 mRNA expression predicts favorable outcome after first line monotherapy with pembrolizumab, while no change or decrease might serve as an indicator of poor outcome and might give cause for early treatment escalation for instance by addition of chemotherapy or additional ICI treatment, e.g., against CTLA-4.

RESUMO

Background Elderly patients (70 years or older) with non-small cell lung cancer (NSCLC) do benefit from systemic chemotherapy as shown in many studies. We prospectively collected multicentric data on therapeutic decisions from patients 70 years or older to reflect the reality in the German health care system. Material and Methods Patients 70 years or older with NSCLC Stage IIIB or IV were eligible. No more than 20 consecutive patients from each center were included. Comorbidities, weighted by the Charlson-comorbidity-index, and survival data were collected. Results 253 patients were documented. Median age was 75.5 years (range 70 to 92) and 75 % were male. 2 % had no comorbidities, 5 % one, 15 % two, 24 % three and 55 % more than three. 237 patients (94 %) received systemic chemotherapy: 172 (73 %) as a combination and 58 (24 %) as monotherapy. Data from seven patients regarding therapy are missing. Combination regimens were in 66 % carboplatin- and in 30 % cisplatin-based. The most frequently given monotherapy was vinorelbin in 50 % of cases. In the group of the patients older than 80 years (n = 38), 53 % received mono therapy, 29 % a carboplatin-based regimen and 16 % no chemotherapy. Cisplatin was not administered in this age group. Median overall survival (OS) was 16.9 months. Patients with a Charlson-score ≤ 6 had 17.9 months, those > 6 12.0 months. With combination chemotherapy median OS was 23.5 months. Patients > 80 years had a median OS of 5.7 months. Conclusion A high percentage of patients older than 70 years received systemic therapy. Survival depended more on comorbidities than on age.
