Abstract
Background: Ramucirumab with either solvent-based or nanoparticle albumin-bound paclitaxel is a standard second-line treatment for advanced gastric cancer. Reportedly, nanoparticle albumin-bound paclitaxel has activated the immune system, but the efficacy of taxane-based agents before nivolumab remains unclear. Therefore, we investigated the prognostic effect of ramucirumab with solvent-based or nanoparticle albumin-bound paclitaxel as second-line therapy, followed by nivolumab as third-line therapy.
Methods: This retrospective study enrolled 115 patients with gastric cancer treated with ramucirumab in combination with solvent-based paclitaxel or nanoparticle albumin-bound paclitaxel from 2017 to 2019 at six hospitals. All patients received nivolumab as a third-line therapy. Ramucirumab + solvent-based paclitaxel and ramucirumab + nanoparticle albumin-bound paclitaxel were administered to 57 and 58 patients, respectively.
Results: The progression-free survival of the ramucirumab + solvent-based paclitaxel group was slightly better than that of the ramucirumab + nanoparticle albumin-bound paclitaxel group but with no statistically significant difference (5.3 months vs. 4.2 months). Contrary, the overall survival of the ramucirumab + nanoparticle albumin-bound paclitaxel group was slightly better than the ramucirumab + solvent-based paclitaxel group but with no statistically significant difference (19.0 months vs. 12.5 months). The multivariate analysis of progression-free survival revealed that ramucirumab + nanoparticle albumin-bound paclitaxel was an independent risk factor for poor prognosis, whereas ramucirumab + nanoparticle albumin-bound paclitaxel was an independent factor for good overall survival.
Conclusions: Ramucirumab + nanoparticle albumin-bound paclitaxel may prolong overall survival when administered before nivolumab, despite its limited effect on progression-free survival.
期刊介绍:
The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
