[Nanoparticle albumin-bound Paclitaxel for unresectable or recurrent gastric cancer].

The efficacy and safety of nanoparticle albumin-bound paclitaxel(nab-paclitaxel)administered every 3 weeks for unresectable or recurrent gastric cancer was evaluated retrospectively. Nab-paclitaxel was intravenously administered at 260 mg/ m² on day 1 of each 21-day course without anti-allergic premedication until disease progression or discontinuation. Nine patients received nab-paclitaxel. The overall response rate was 11.1%, and the disease control rate was 55.6%. Grade 3/4 toxicities included neutropenia(44.4%), leukopenia(33.3%), and peripheral sensory neuropathy (33.3%). It is important to manage both neutropenia and peripheral neuropathy. Although only few cases were analyzed, therapeutic effect can be obtained even with the starting dose of 180 mg/m² suggesting management of toxicities will be feasible. In view of the toxicities observed, a reduced starting dose of 180 mg/m² should be considered in the case of poor performance status patients. Nab-paclitaxel is a promising drug because of its convenience and may replace weekly paclitaxel for unresectable or recurrent gastric cancer.
