PURPOSE The German Society of Pediatric Hematology and Oncology (GPOH) conducted a randomized, prospective, multicenter trial (HIT '91) in order to improve the survival of children with medulloblastoma by using postoperative neoadjuvant chemotherapy before radiation therapy as opposed to maintenance chemotherapy after immediate postoperative radiotherapy.(More)
PURPOSE To investigate whether radiotherapy can be reduced without loss of efficacy from extended field (EF) to involved field (IF) after four cycles of chemotherapy. PATIENTS AND METHODS Between 1993 and 1998, patients with newly diagnosed early-stage unfavorable HD were enrolled onto this multicenter study. Patients were randomly assigned to receive(More)
PURPOSE The study was initiated to obtain epidemiologic data and information on anatomic and histologic distribution, clinical features, and treatment results in patients with primary gastrointestinal non-Hodgkin's lymphomas (PGI NHL). PATIENTS AND METHODS Between October 1992 and November 1996, 371 PGI NHL patients were eligible to evaluate clinical(More)
PURPOSE Combined-modality treatment consisting of four to six cycles of chemotherapy followed by involved-field radiotherapy (IFRT) is the standard of care for patients with early unfavorable Hodgkin's lymphoma (HL). It is unclear whether treatment results can be improved with more intensive chemotherapy and which radiation dose needs to be applied. (More)
PURPOSE In the prospective study 02/96 on primary GI lymphoma, we have collected data on histology, clinical features, and treatment results. In particular, in stages I and II localized primary gastric lymphoma (PGL), our objectives were to reduce treatment intensity and to confirm our hypothesis from study 01/92, which maintained that an organ-preserving(More)
PURPOSE The impact of different local therapy approaches on local control, event-free survival, and secondary malignancies in the CESS 81, CESS 86, and EICESS 92 trials was investigated. METHODS AND MATERIALS The data of 1058 patients with localized Ewing tumors were analyzed. Wherever feasible, a surgical local therapy approach was used. In patients with(More)
BACKGROUND Local failure after radical prostatectomy (RP) is common in patients with cancer extending beyond the capsule. Three prospectively randomized trials demonstrated an advantage for adjuvant radiotherapy (ART) compared with a wait-and-see (WS) policy. OBJECTIVE To determine the efficiency of ART after a 10-yr follow-up in the ARO 96-02 study. (More)
The precise pathophysiological mechanisms of radiation-induced lung injury are poorly understood, but have been shown to correlate with dysregulation of different cytokines. The purpose of this study was to evaluate the time course of the pro-inflammatory cytokines tumor necrosis factor-(TNF-)α, interleukin-(IL-)1α and IL-6 after whole-lung irradiation. The(More)
PURPOSE The lung is the major dose-limiting organ for radiotherapy of cancer in the thoracic region. The pathogenesis of radiation-induced lung injury at the molecular level is still unclear. Immediate cellular damage after irradiation is supposed to result in cytokine-mediated multicellular interactions with induction and progression of fibrotic tissue(More)
The long-term results of radiotherapy in primary carcinoma of the vagina are not well defined. The treatment results of 41 patients with primary malignancies of the vagina were analyzed. The mean follow-up period was 77.3 months (2.3–404 months). The predominant histology was squamous cell carcinoma, FIGO stages I: n = 7 (17.1%), II: n = 13 (31.7%), III: n(More)
