Efficacy and Safety Study of Combination Therapy With Docetaxel-oxaliplatin-capecitabine in Patients With Advanced Gastric Adenocarcinoma and Intermediate General Status

Phase II Study of Adjusted-dose Docetaxel-oxaliplatin-capecitabine in Patients With Advanced Gastric Adenocarcinoma and Intermediate General Status.

The purpose of the study is to determine efficacy and safety of combination therapy with adjusted-dose docetaxel-oxaliplatin-capecitabine in patients with advanced gastric adenocarcinoma and intermediate general status.(defined as ECOG 2 or weight loss 10-25% or older that 70 years and no comorbidities nor functional dependency nor geriatric syndrome)

Inclusion Criteria:

1. informed consent signed
2. Histological or cytological adenocarcinoma confirmation carcinoma on the esophago-gastric union or stomach (type I, II and III Siervent) metastatic or relapsed
3. measurable disease (following RECIST criteria)
4. older or equal 70 years old
5. Intermediate general status defined as at least one of the following characteristics: performance status (ECOG) = 2, weight loss ponderada between 10 and 25% in the last 3 months
6. life expectancy superior to 12 weeks
7. adequate hematological function: Neutrophils ≥1.50x109, platelets ≥100x109, Hemoglobin ≥10 g/dl
