Survival analysis of the metastatic cohort of Italian Association of Medical Oncology (AIOM) GARIBALDI survey

This analysis from the GARIBALDI study was aimed to address the role of center self-declared expertise, type and commitment on the overall survival (OS) of patients with metastatic Pancreatic Ductal Adenocarcinoma (mPDAC). Treatment-naïve patients ≥18-year with pathological diagnosis of mPDAC were enrolled. OS was defined as the time from chemotherapy start to death from any cause. The impact of clinical-demographic and centers characteristics on OS was evaluated using Cox models. Between July 2017 and October 2019, 473 patients enrolled in 43 centers were eligible for this analysis. Median age was 69.3 (first-third quartile 61.2–74.5); 46.1 % females; 90.8 % ECOG PS 0–1; 67.4 % had liver metastases; median CA19.9700.5 UI/mL (first-third quartile 77.5-6629.5). For 37.1 % of patients chemotherapy started <4 weeks from diagnosis; 69.9 % of patients received nab-paclitaxel + gemcitabine; 16.9 % gemcitabine alone; 7.6 % FOLFIRINOX. The median follow-up was 51.8 months and 428 patients died. No statistically significant role of the type of institution was observed. Additionally, no statistically significant role of neither the self-declared expertise nor the accrual rate was observed. The GARIBALDI study suggests that the self-declared center expertise and the academic brand are not associated to OS in patients with mPDAC, while center commitment warrants further exploration.
