[Non-radical surgery of malignant pelvic tumors]

Because of an often excessive tumor extension, radical surgical resection of malignant tumors of the pelvis was possible in only half of our patients. Until now we refused to perform hemicorporectomy. In view of a temporary improvement of the quality of life it seems reasonable to perform these radical and palliative operations, even if a high recurrence rate can be anticipated. As for the survivor-rate, no exact conclusions can be drawn from our results. The possibility of a radical resection is largely dependent upon the tumor's localisation (I, III) i.e. most of the periacetabular tumors additionally involve several regions of the pelvis (II + III + I). In the region of the sacrum (IV) a radical resection could not be achieved in our patients. Functionally, type I and III resections show the best results. These days there is a good chance of achieving a satisfying result with endoprosthetic reconstruction of the pelvis following resection of periacetabular tumors--however a high complication rate has to be taken into account.
