Abstract

Background This study evaluated the safety and efficacy of nab-paclitaxel as second-line treatment in patients with advanced gastric adenocarcinoma.

Methods Thirty-nine pretreated patients [33 with taxane-based regimens (docetaxel, cisplatin, and fluorouracil)] and 6 with combination of fluoropyrimidines plus cisplatin with locally advanced inoperable and metastatic gastric and gastroesophageal junction adenocarcinoma were treated with weekly nab-paclitaxel (150 mg/m2 d1, d8, d15 in cycles of 28 days).

Results Partial response (PR) was documented in nine patients (23.1%; 95% confidence interval 10.1-37.2%), stable disease (SD) in 11 (28.2%) and disease progression in 18 (46.2%). The disease control rate (SD + PR + complete response) was 51.3%. Grade 3 and 4 neutropenia occurred in 10.2% and 5.1% of patients, respectively; grade 3 anemia in 5.1%; grade 3 neurotoxicity in 5.1%; and grade 2 pain in 5.1%. The median progression-free survival was 3.0 months (range 0.3-13.6) and the median overall survival 6.8 months (range 0.3-22).

Conclusion Nab-paclitaxel as second-line treatment in locally advanced inoperable or metastatic gastric and gastroesophageal junction carcinoma is an active chemotherapy regimen with a manageable toxicity profile and merits further evaluation.
