Home Parenteral Nutrition for Malnourished Unresectable Stage IV Gastric Cancer

Objectives:

• Primary Objective:

The primary end points are overall survival and cycles of salvage chemotherapy completed of malnourished patients in unresectable mGCs

• Secondary Objectives:

Side effects of salvage chemotherapy, quality of life, nutritional status, performance status, inflammatory status, safety and complications of HPN. The visit time schedules are at the time of enrollment before HPN is delivered, and at the beginning of every cycle of salvage chemotherapy

Patient Selection and Enrollment:

Twenty patients are planed to be enrolled

Drop out The following reasons may consider to withdrawing a patient from the study

• Intolerance adverse events
• Patient will exceed defined safety cut-off values e.g. increase of a certain amount of a laboratory parameter.
• Violation of study protocol
• Withdraw of informed consent.

Study duration and dates The study of this protocol is expected to be approximately 24 months, with a subject recruitment period of 18 months (proposed to start in Sep 2014 and end in Sep 2018). The duration of the study or period of recruitment may vary.

Treatment duration HPN is administered till resolution of malnutrition or till patient dies

Exclusion criteria

• Known allergy to components of studied parenteral nutrition.
• Acute shock or collapse.
• Known diabetic ketoacidosis 7 days prior to randomization.
• Unstable conditions (e.g. uncompensated diabetes mellitus, acute myocardial infarction, embolism, metabolic acidosis, severe sepsis and hypotonic dehydration).
• General contraindications to infusion therapy: acute pulmonary edema, hyperhydration, uncompensated cardiac insufficiency.
• Investigator judges as subjects to be inappropriate for the clinical study (e.g., patient with severe complications)
