- Primary outcomeEfficacy and safety assessments Objective response as determined by SWOG criteria is the main efficacy endpoint. Upon entry, subjects must have at least one measurable site of disease based on the SWOG response criteria. All lesions must be identified at baseline by physical exam, CT or MRI within 2 months prior to the start of treatment. Changes from baseline will be assessed 6 weeks after the last treatment, and 3, 6, and 12 months after the last treatment, and then every 6 months, until progression occurs. Patients who discontinue early due to clinical disease progression (unsatisfactory therapeutic effect) do not require a tumor assessment. The overall survival of patients treated with radiolabelled somatostatin analogue will be calculated from the first day of treatment until the day of death. In patients who change to other anti-tumor treatments or who are lost to follow-up censored survival will be determined by the last regular visit. The time to progression is calculated from the first day of treatment to the day of documented progression. Tumor Assessment/SWOG For CT imaging at entry, a triphasic, contrast enhanced study should be performed with a slice distance of 5 or 8 mm, and continuous slices. For follow-up CT imaging, triphasic imaging is not mandatory: the imaging phase at which the lesions are best recognized can be repeated instead. Tumor response will be recorded according to the SWOG criteria by the investigators. Bidimensional tumor measurements from CT or MRI scans that were performed before treatment enrollment and after completing the therapy will be recorded. End of Study The completion of the last day of the last study period or the date and reasons of premature discontinuation from the study, will be recorded. End-point of the follow-up period is disease progression or death. The follow-up may be ended 5 years after the conclusion of treatment. However, in all patients the collection of toxicity data (hematology, renal function) should be continued either by the investigator, referring physician, or general practitioner. Survival Information Information regarding the status of the patient, date of last contact or date of death will be collected.
- Secondary outcome1. Changes in serum chromogranin-A concentrations. 2. Safety of treatment as measured by the rate of adverse events and the monitoring of selected laboratory evaluations. 3. Effect of the different treatment arms on Quality of Life as measured by the EORTC QLQ-C30 questionnaire. 4. Effects on tumor growth rate (TGR).

- Brief summaryNeuroendocrine Gastro-Entero-Pancreatic (GEP) tumors are rare neoplasms that usually grow slowly and have a relatively benign course. They can be divided in carcinoids and islet-cell tumors. In inoperable and/or metastasized disease, tumor-targeted peptide radionuclide radiation therapy (PRRT) with [177Lu-DOTA0,Tyr3]octreotate (177Lu-octreotate) may be very rewarding. From January 2000 to July 2006, 1968 treatment cycles with 177Lu-octreotate in 562 patients were administered at Erasmus MC. In an analysis in 131 GEP-tumor patients, 28% had PR and 19% had a minor response (MR, 25-50% tumor volume reduction). The reason to study the effect of chemosensitization in the current protocol is based on the fact that such chemosensitization has been shown advantageous in a variety of tumor types treated with fractionated radiotherapy. Also, chemosensitization with 5-FluoroUracil (5-FU) in combination with 90Y-labelled antibody radioimmunotherapy is feasible and safe. Lastly, the results of the combination of 5-FU with 111In-DTPA-octreotide treatment compare favourably to treatment with 111In-DTPA-octreotide only. The prodrug of 5-FU, capecitabine, was also shown effective in combination with concomitant external beam radiotherapy. It has the advantage over 5-FU of oral administration. Additionally, higher concentrations in many tumor tissues of the enzyme thymidine phosphorylase, which converts the prodrug to its active form, may be another advantage of capecitabine over 5-FU. The mechanism by which halogenated pyrimidines such as 5-FU potentiate radiation damage is their incorporation in the DNA, making it more susceptible to radiation therapy. Also, 5-FU inreferes with the cellular mechanisms that repair sublethal cell damage. Until now, no controlled comparative studies with radiolabelled octreotide or octreotate have been performed. The differences between the results in the currently available reports may be partly due to differences in treatment protocols and in patient selection. Therefore, a controlled study comparing the best strategies for PRRT is warranted. For the reasons outlined above, 177Lu-octreotate and a combination of capecitabine and 177Lu-octreotate are likely candidates. A two-armed randomized controlled study is proposed to address the main question, whether there are clinically important differences in response rate between 177Lu-octreotate and the combination of capecitabine and 177Lu-octreotate, when used to treat patients with somatostatin-receptor positive GEP tumors.
