Maintenance Treatment With S-1 in Gastric Cancer Patients

7 de outubro de 2018 atualizado por: Ruihua Xu, Sun Yat-sen University

Maintenance Treatment With S-1 Versus Observation After First-line Chemotherapy in Patients With Advanced Gastric Cancer: a Randomized Phase II Study

Gastric cancer remains the third leading cause of cancer-related death worldwide and is especially frequent in East Asia. Fluoropyrimidines are the backbone of first-line chemotherapy for advanced gastric cancer (AGC), and S-1 provides new option with its simplicity and convenience.

5-Fluorouracil (5-FU) was the only efficacious treatment for AGC before the nineties of the 20th century, and afterwards with the discovery of chemotherapy such as cisplatin, oxaliplatin, S-1 and capecitabine, response rate as well as survival had been improved greatly.

Most of AGC will progress after first-line treatment; therefore, seeking an efficient and low toxic maintaining regimen to prolong progression-free survival (PFS) becomes a hot topic in oncologic field. Some clinical researches demonstrated maintenance treatment for advanced colorectal cancer (CRC) and lung cancer. The investigators had conducted a phase III clinical trial that demonstrated capecitabine maintenance versus observation prolonged PFS significantly after first-line chemotherapy with FOLFOX or XELOX regimens in advanced CRC. In AGC, several retrospective studies revealed patients receiving 5-FU/leucovorin(LV), capecitabine, or trastuzumab maintaining therapy experienced significantly longer PFS than that stopped chemotherapy after first-line chemotherapy. Some one-arm phase II clinical trials found 5-FU/LV, capecitabine, S-1, capecitabine plus bevacirumab, or capecitabine plus bevacirumab plus trastuzumab maintenance seemed to yield sound PFS and good tolerance. However, there were no randomized controlled clinical trials for maintenance treatment of these regimens in AGC, except that a phase II Chinese randomized controlled trial of Uracil and Tegafur (UFT) versus observation experienced early termination.

Above all, so far, there is no data to demonstrate that regular 2-6 months of chemotherapy followed by maintenance treatment could prolong PFS and OS for AGC. S-1 is effective for gastric cancer, and was approved as palliative treatment for advanced gastric cancer and adjuvant treatment; in addition, with its relative less frequency of side effects and convenient oral administration, S-1 as maintenance regimen could be prone to be accepted by patients. Therefore, the current study is designed to investigate that S-1 as maintenance treatment after first-line palliative chemotherapy could improve PFS and OS for patients with advanced gastric cancer through a perspective randomized clinical study.

Visão geral do estudo

Descrição detalhada

Patients with AGC who achieved objective response or stable disease after 2-6 months of first-line chemotherapy were randomly assigned to one of two groups, to receive either S-1 (40 mg for BSA<1.25 m2, 50 mg for 1.25≤BSA<1.50 m2 and 60 mg for BSA≥1.50 m2 b.i.d. on days 1-14, q3w) as maintenance therapy or observation. The treatment will continue until disease progression or unacceptable toxicity.
