[The role of postoperative radiotherapy in the treatment of XXXX ].

@entity1 @entity1358 @entity5 @entity3
The following results can be derived from the clinical and radiobiological literature as well as from the authors's own experiences with 91 @entity1 analyzed retrospectively and evaluated with respect to their risk factors. 1. A postoperative irradiation is very probably sensible in @entity1 with @entity5 perforation through the renal capsule (T3/T4) and with venous or lymph node manifestations. 2. The operation method is essential, above all the transabdominal technique and the quality of lymph dissection. 3. Prospective studies are necessary in order to clear up the role of radiotherapy in @entity1 with lymph node manifestations and the other two risk factors mentioned in item 1. 4. Further studies on the @entity5 biology of the @entity1358 are necessary in order to gain prognostic criteria allowing a pretherapeutic sensitivity recognition. 5. The effect of a supplementary radiotherapy can be only that of local recurrence prevention in case of a locally advanced @entity5 and the absence of demonstrable remote @entity3 . This seems justified, because the local recurrence rate in our own @entity1 was only 3.3%.
