Comparative Study
Survival benefit with radiation therapy in node-positive breast carcinoma patients.
Postoperative radiation therapy (RT) has been the subject of discussion, especially in patients with one to three positive lymph nodes (< or = 3 pN+) in the axillary dissection. The authors investigated whether postoperative RT provides a survival benefit for pT1-2 pN+ breast cancer patients. ⋯ RT provides a survival benefit in patients with < or = 3 or > or = 4 pN+; the indication for postoperative RT should therefore be adapted in future consensus meetings.

The optimal radiochemotherapy regimen for advanced head-and-neck cancer is still debated. This nonrandomized study compares two cisplatin-based radiochemotherapy regimens in 128 patients with locally advanced unresectable stage IV squamous cell carcinoma of the head and neck (SCCHN). ⋯ Two courses of fractionated cisplatin (20 mg/m(2)/day) alone appear preferable, as this regimen resulted in similar outcome and late toxicity as two courses of cisplatin + 5-FU, but in significantly less acute toxicity.

Timing and sequencing of radiotherapy in the context of allogenous breast reconstruction have not been standardized. The aim of the present study was to assess the influence of adjuvant radiotherapy on morbidity and patient satisfaction after allogenous breast reconstruction. ⋯ Adjuvant radiotherapy with the use of a subtotally filled expander prior to definitive allogenous breast reconstruction is feasible with acceptable morbidity. An interdisciplinary consultation concerning the cosmetic outcome and potential side effects is absolutely necessary.

Randomized Controlled Trial
Effect of a prostaglandin--given rectally for prevention of radiation-induced acute proctitis--on late rectal toxicity. Results of a phase III randomized, placebo-controlled, double-blind study.
To assess the late effect of a prostaglandin, given rectally during irradiation, on late rectal toxicity. In the acute treatment setting no significant differences in reducing the incidence of acute proctitis symptoms in patients receiving misoprostol, however, significantly more rectal bleeding had been reported. ⋯ Misoprostol given as once-daily suppository for prevention of acute radiation-induced proctitis does neither influence the incidence and severity of radiation-induced acute nor late rectal toxicity. Misoprostol has no negative impact on the incidence and severity of late rectal bleeding, in contrast to acute rectal bleeding. The routine clinical use of misoprostol suppositories cannot be recommended.

To evaluate the structure quality (medical staff, linear accelerators, and patients) of radiotherapy units based on the clinical audits by the "Arztliche Stelle" (this institution is based on federal German law) in Baden-Württemberg. ⋯ Clinical audits by the "Arztliche Stelle" are highly effective to evaluate the structure quality of radiotherapy units. Based on these audits realistic data for staff requirements were gained. Making use of these data, guidelines for average minimum personnel necessary for good patient care were calculated. Personnel requirements may vary related to specific needs (teaching, research) of the treatment program and should be accounted for when discussing with the administration. The recommendations of the auditors of the "Arztliche Stelle" resulted in the new employment of additional staff.
