Popis: | 4056 Background: Ramucirumab as monotherapy or in combination with paclitaxel is a second-line treatment option recommended for patients with locally advanced unresectable or metastatic gastroesophageal junction (GEJ) or gastric adenocarcinoma. However, real-world data of large samples focused on ramucirumab plus paclitaxel in gastric cancer are limited. We conducted a nationwide retrospective study to evaluate the efficacy, safety, and factors potentially associated with survival in patients with gastric or GEJ adenocarcinoma who received second-line ramucirumab plus paclitaxel in a real-world setting. Methods: The study population comprised all patients with gastric or GEJ cancer who received ramucirumab plus paclitaxel in South Korea between May 1, 2018, and December 31, 2018. We included patients with advanced gastric or GEJ adenocarcinoma and disease progression after first-line platinum and fluoropyrimidine-containing combination chemotherapy. Results: A total of 1,063 patients with advanced gastric or GEJ adenocarcinoma who received ramucirumab plus paclitaxel were included. The objective response rate and disease control rate were 15.1% and 57.7%, respectively; the median progression-free survival was 4.03 months (95% CI, 3.80–4.27), and the median overall survival was 10.3 months (95% CI, 9.33–10.73). The common treatment-related adverse events (TRAEs) at any grade were neutropenia (44.7%), anemia (41.8%), neuropathy (29.1%), fatigue (25.9%), and anorexia (25.0%). Grade 3 or higher TRAEs with incidences of ≥5% were neutropenia (35.1%) and anemia (10.5%). Adverse events of special interest were infrequent, including hypertension (2.1%) and proteinuria (3.0%). Based on multivariate analysis, overall survival was negatively associated with Eastern Cooperative Oncology Group performance status ≥2, weight loss in the previous 3 months ≥10%, GEJ of primary tumor, poor or unknown histology grade, number of metastatic sites ≥3, presence of peritoneal metastasis, no prior gastrectomy, and time to second-line since first-line treatment < 6 months. Conclusions: Our large-scale, nationwide, real-world data analysis of an unselected real-world population added evidence for the efficacy and safety of second-line ramucirumab plus paclitaxel in patients with locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma.
