Desmoid tumors are non-metastatic mesenchymal tumors with an aggressive local growth. Depending on the anatomic location, morbidity varies. We report of a patient with a desmoid tumor of the right shoulder which was treated in our department by surgical excision, plastic-surgical wound closure and postoperative adjuvant radiation.

Purpose: To compare the outcomes of four cisplatin-based radiochemotherapy regimens in 311 patients with Stage III/IV squamous cell carcinoma of the head and neck.

Methods And Materials: Concurrent chemotherapy consisted of three courses of cisplatin 100 mg/m(2) on Day 1 (Group A, n = 74), two courses of cisplatin 20 mg/m(2) on Days 1-5 plus 5-fluorouracil 1,000 mg/m(2) on Days 1-5 (Group B, n = 49), two courses of cisplatin 20 mg/m(2) on Days 1-5 plus 5-fluorouracil 600 mg/m(2) on Days 1-5 (Group C, n = 102), or two courses of cisplatin 20 mg/m(2) on Days 1-5 (Group D, n = 86). The groups were retrospectively compared for toxicity and outcomes, and 11 additional factors were evaluated for outcomes.

Objective: Many patients with brain metastases due to SCLC have a poor survival prognosis. The most common treatment is whole-brain radiotherapy (WBRT). This retrospective study compares short-course WBRT with 5x4Gy in 1 week to standard WBRT with 10x3Gy in 2 weeks.

Purpose: The majority of patients with brain metastases from melanoma receive whole-brain radiotherapy (WBRT). However, the results are poor. Hypofractionation regimens failed to improve the outcome of these patients.

Background And Purpose: Conventional radiotherapy (RT) still is the standard technique for head-and-neck cancer in many centers worldwide, whereas other centers replaced this technique by 3-D conformal RT, which is associated with more appropriate dose distributions. Comparative studies regarding outcome and toxicity are lacking. This study compared both techniques for overall survival (OS), metastases-free survival (MFS), loco-regional control (LC), and toxicity in stage III/IV head-and-neck cancer.

Background And Purpose: Whole-brain radiotherapy (WBRT) is the most common treatment for brain metastases. Most of these patients have a poor survival prognosis. Therefore, a short radiation program is preferred, if it provides a similar outcome as longer programs.

Background: Whole brain radiotherapy (WBRT) is the most common treatment for brain metastases. Survival of patients with cancer of unknown primary (CUP) presenting with brain metastases is extremely poor. A radiation program with a short overall treatment time (short-course RT) would be preferable to longer programs if it provides similar outcomes.

Background: The objective of this study was to compare stereotactic radiosurgery (SRS) alone with resection plus whole-brain radiotherapy (WBRT) for the treatment of patients in recursive partitioning analysis (RPA) class 1 and 2 who had 1 or 2 brain metastases.

Methods: Two hundred six patients in RPA class 1 and 2 who had 1 or 2 brain metastases were analyzed retrospectively. Patients in Group A (n = 94) received from 18 grays (Gy) to 25 Gy SRS, and patients in Group B (n = 112) underwent resection of their metastases and received 10 x 3 Gy/20 x 2 Gy WBRT.
