Exceptions are, adequately treated basal cell carcinoma or squamous cell carcinoma of the skin or, other previous malignancy with a disease-free interval of at least 5 years.\n4. Two or more synchronous primary cancers in the pelvic region at time of diagnosis\n5. Previous radiotherapy, surgery or chemotherapy that may interfere with the planned treatment for the present disease, as judged by the investigator.\n6. Co-existing disease prejudicing survival (expected survival should be \\>2 years).\n7. Pregnancy or breast feeding\n8.
