- Part I (surgical resection, tumor xenografts generation, and drug selection): Patients undergo surgical resection. The resected tumor tissue is implanted in laboratory mice to generate tumor xenografts. The mice are then treated with a series of 10 approved anticancer drugs, whose anticancer activity are ranked from the most to the least effective based on response of the tumor xenografts. The most effective drug is identified for the individual patient. Patients for whom no drug is found to be effective are removed from the study. Patients who develop progressive disease after surgical resection and after mice data is available proceed to part II.
