5 mg/dl) and liver (serum bilirubin ≤2 mg/dL) functions, normal cardiac function, absence of second primary tumor other than non-melanoma skin cancer or in situ cervical carcinoma, no central nervous system involvement, no prior radiotherapy in target lesions, and no concurrent uncontrolled medical illness. selleck compound Patients received every 2 weeks irinotecan 180 mg/m2 as 1 h infusion on day 1, folinic acid 100 mg/m2 intravenously days 1–2, and fluorouracil as a

400 mg/m2 bolus and then 600 mg/m2 continuous infusion over 22 hours days 1–2. The dose of irinotecan was reduced to 150 mg/m2 in patients older than 70 years. Chemotherapy was generally administered on an outpatient basis for a maximum of 12 cycles. Treatment was continued until disease progression or unacceptable toxicity. Toxicity was graded according to the National Cancer Institute-Common Toxicity Criteria version 4.0 (NCI-CTC v. 4.0). Tumor response was evaluated according to the response evaluation criteria for solid tumors (RECIST 1.1). Progression-free survival (PFS) and

overall survival (OS) were calculated from the date of therapy initiation to the date of disease progression, death from any cause or last follow-up evaluation, respectively. PFS and OS were analyzed according to the Kaplan-Meier method. The Cox proportional hazards regression model was used for univariate AZD1390 molecular weight analysis of prognostic factors for survival. All statistical analyses were performed using SPSS statistical software version 20 (SPSS inc.,Chicago IL, USA). The study was approved by the coordinating centre’s Lumacaftor research buy Ethics Committee at the “Regina Elena” National Cancer Institute, Rome, and was carried out according to the principles of the Declaration of Helsinki. A written informed consent was obtained from all patients. Results

Patients characteristics Seventy patients with a median age of 65 years (range, 32–75) were included in this study. Patients’ characteristics are illustrated in Table 1. The primary tumor site was stomach in 54 patients (77%) and the GEJ in 16 patients (23%). The histology subtype was diffuse, intestinal and unknown in 33 (47%), 29 (41.5%), and 8 (11.5) patients, respectively. Primary tumor resection was carried out in twenty-five patients (36%). The ECOG PS was 0, 1 and 2 in 10 (14.5%), 40 (57%) and 20 (28.5%) patients, respectively. Fifty-three patients (76%) had two or more metastatic sites. PFS during first-line chemotherapy was ≥ 6 months in 42 patients (60%), and the chemotherapy-free interval was > 3 months in 38 patients (54%). Among regimens administered in the first-line setting, 25 patients (36%) received docetaxel, oxaliplatin and capecitabine [15], 20 patients (28.5%) received epirubicin, cisplatin and docetaxel [16], 19 patients (27%) were treated with epirubicin, oxaliplatin and docetaxel [17], and 6 patients (8.5%) received cisplatin and docetaxel [18].
