      Background
      Customization is feasible in adjuvant setting (tissue availability). SCAT trial has completed planned recruitment with 500 p. For resected NSCLC with nodal involvement adjuvant platinum-based CT improves outcomes but survival remains suboptimal. Compliance may be a key issue for efficacy in adjuvant setting. mRNA BRCA1 levels are prognostic in early NSCLC and could be a predictive marker for CT activity. In advanced disease patients with low BRCA1 benefit from cisplatin doublets meanwhile p with high levels attained longer survival with taxanes.

      Methods
      Phase III trial testing 4 cycles non-selected vs customized adjuvant CT. Entry criteria: NSCLC, R0 resection, pN1 or pN2, KI > 70, recovered from surgery, adequate hematologic, renal and liver functions, no prior CT or RT, age > 18 y, informed consent. Stratification: N1 vs N2, histology (squamous vs non-squamous), resection (lobectomy vs pneumonectomy). Central lab mRNA BRCA1 levels and quartile distribution. Primary end-point: OS. Secondary end-points: DFS, toxicity, recurrence pattern. Design: R: 1:3. Control treatment: Cis-Docetaxel (CD). Experimental arm: Q1: Cis-Gemcitabine (CG); Q2-3: Cis-Docetaxel; Q4: Docetaxel (D). PORT in pN2 patients. Compliance treatment and toxicity profile analyzed by arm and correlation with potential prognostic factors explored

      Results
      500 included p; 108 control arm, 392 experimental arm. Median follow-up 18.6 m (2-59 m). Median mRNA BRCA1 levesl 15.78 (0.73-132) Q1 212 (42.4%), Q2-3 150 (30%), Q4 138 (27.6%). Mean BRCA1: Adenocarcinoma: 8.45 vs Squamous 19.6 (p< 0.001). Overall low levels BRCA1: 43.8%. EGFR mut 5.6% 297 p evaluated for compliance planned adjuvant treatment: M/F ratio: 82.5/17.5%. Median age: 62 (range 36-80). PS 0/1/2: 55.9/43,1/1%. Histology: Adenocarcinoma 47.5%, Squamous 44.1%. Stages: IIA/IIB/IIIA: 11.1/38.4/50.2%. Surgical procedure: Lobectomy 72.1%; Pneumonectomy 27.9%.. Toxicity. G3-4 AE: Neutropenic fever: CD 10% vs D 4.4% vs CG 0%. (p=0.0056); Nausea/vomits: CG 11.1% vs CD 10.4% vs D 0%. (p=0.0198); Hypersensitivity: D 5.97% (NS). Dose-reduction: 34.24% control vs 18.30% experimental (p=0.0044). Full 4 cycles CT compliance: CD control 80.83%, CG 91.2%, CD experimental 79.2%, D 88.1% (p=0.052). No differences in dose-reductions. CT compliance lobectomy 86.4% vs 85.5% pneumonectomy (NS). CT compliante < 70 y 91.1% vs 66.6% > 70 y (p<0.01)PORT compliance 55.31% of planned cases.

      Conclusion
      Planned trial recruitment achieved with median f-u 18.6 m. Majority of resected NSCLC showed low levels expression BRCA1. Adenocarcinoma lower levels than Squamous. Safety profiles differences observed between treatment schedules: neutropenic fever (CD), nausea/vomits (CG). Customized treatment requires less dose-reductions. Trend to poor compliance with Cis-Doc. No relation between extensión of surgery and adjuvant Tx compliance . Compliance CT significantly lower for age > 70 y. Low compliance for PORT.

      P1.11-005 - EVEREST Study: Evolution of disease-related symptoms of patients (p) with advanced non-small cell lung cancer (NSCLC) and its correlation with response to first-line (1L) treatment. (ID 3277)

      • Abstract

      Background
      The control of symptoms to maintain the health-related quality of life continues to be a priority in the treatment of advanced NSCLC. The aim of our study was to assess the evolution of the disease-related symptoms and, due to the lack of evidence, to evaluate its correlation with the response to 1L treatment in p with advanced NSCLC.

      Methods
      EVEREST is an observational prospective study carried out in 33 Spanish institutions. A total of 155 p with advanced NSCLC initiating standard platinum-based 1L treatment were included. Disease-related symptoms were assessed at baseline and after completing 4-6 cycles of 1L treatment (final visit) with the Lung Cancer Symptom Scale (LCSS) and an ad-hoc specific questionnaire evaluating their frequency. Response to treatment was assessed according to RECIST criteria.

      Results
      Baseline characteristics of the 155 p enrolled were: 76.1% male, 96.1% Caucasian, 70.3% adenocarcinoma, 16.8% squamous-cell carcinoma; median age was 62 years. ECOG PS 0/1/2: 26.5%/54.8%/14.8%. 65.3% and 12.9% of p maintained or improved the ECOG status during the study, respectively. 118 p completed at least 4 cycles of treatment. Best response to 1L treatment was: 1.7% complete response, 68.4% partial response and 26.5% stable disease. Most frequent disease-related symptoms were asthenia and pain. 1L treatment did not deteriorate disease-related symptoms compared to baseline (LCSS score was reduced 1.4 points) and an improvement in cough was observed (p=0.026). The frequency of cough (p<0.001), dyspnea (p=0.025), pain (p=0.009) and discomfort (p=0.034) were significantly reduced. No significant correlation with response to treatment and the evolution of symptomology between visits was found.

      Conclusion
      1L treatment was associated with a reduction of the frequency (cough, dyspnea, pain and discomfort) and intensity (cough) of disease-related symptoms in p with advanced NSCLC, irrespective of the response achieved.
