title: ["As much as possible"--an outdated concept in advanced neuroblastoma?].
abstract: Complete tumor resection is often impossible in disseminated stages of neuroblastoma. Therefore, the role of primary tumor resection in neuroblastoma patients of stage III and IV will be discussed here. Between 1972 and 1995, 66 neuroblastoma patients were operated in our department of pediatric surgery, 41 of whom were treated before 1989 and are the subject of retrospective study. Eight children belonged to stage III, 15 to stage IV and two to stage IV-S. Primary tumor resection was carried out in 19 of 25 patients with disseminated tumor stages. Total resection (RO) was achieved in three cases (16%). Microscopic tumor remains (R1) were present in four, with macroscopic remains in 12 cases. Three disseminated neuroblastomas received preoperative chemotherapeutic treatment, followed by a delayed complete operative tumor resection in two cases. Temporary tumor remission after an incomplete primary operation (R2) was achieved with adjuvant postoperative chemo- and radiotherapy in six of 12 patients. The mortality rate was high (stage III: n = 5/8, stage IV: n = 14/15, stage IV-S: n = 2/2). We recommend preoperative chemotherapy in cases of infiltrative tumor growth of stage III and generally in stage IV. This therapeutic regime improves the rate of complete tumor resection with less intraoperative complications.
