Design outcomes

Primary

MeasureTime frame
1. Decrease of the incidence of clinically significant malignant ascites 2. Decrease of the Incidence of intestinal obstruction with the need of surgical intervention or parenteral nutrition 3. Decrease of the incidence of ECOG deterioration 4. Decrease of the incidence of death 5. Every parameter will be analysed separately in comparison to historical controls

Secondary

MeasureTime frame

Immunological monitoring: 2.1. Induction of anti-tumour response 2.2. Quality and quantity of epithelial cell adhesion molecule (EpCAM)-expression 2.3. Disseminated tumour cells and tumour stem cells within the peripheral blood during therapy 2.4. Anti-EpCAM and anti-HER2/neu humoral immune response 2.5. vascular endothelial growth factor (VEGF)-level during therapy 2.6. Induction of human anti-mouse antibodies (HAMA) 2.7.
