Locally advanced breast carcinoma is associated with a poor prognosis. With single treatment modalities, i.e., surgery and/or radiation therapy, results have been consistently dismal. However, several earlier reports have indicated improvement in survival with a combined modality approach, i.e., the utilization of systemic therapy. ⋯ Standard dose preoperative and postoperative FEC therapy combined with surgery and radiotherapy in the era of mammography screening seem to yield results comparable to those achieved with other conventional strategies in the treatment of unscreened populations.

Randomized Controlled Trial Multicenter Study Clinical Trial
A study evaluating the efficacy and tolerability of tropisetron in combination with dexamethasone in the prevention of delayed platinum-induced nausea and emesis.
Chemotherapy-induced emesis is one of the most disturbing side effects of cancer therapy. Control of acute emesis has improved substantially during recent years, but control of delayed emesis and nausea remains a challenging problem. The role of 5-HT3 receptor antagonists in the treatment of delayed emesis is disputed. ⋯ Tropisetron added to dexamethasone improved control of delayed nausea on Day 3 compared with placebo. No significant differences were recorded regarding control of delayed emesis.

Electrochemotherapy (ECT) is performed by locally administering a chemotherapeutic agent in combination with electric pulses. Previous clinical studies have demonstrated the effectiveness of ECT. In these initial trials, the drug was administered intravenously, followed by administration of electric pulses directly to the tumor. This study was initiated to determine whether an intralesional injection of the drug in combination with electric pulses could provide an improved result. A group of 34 patients was studied. ⋯ ECT was shown to be an effective local treatment for cutaneous malignancies. The results suggest that ECT may have a tissue-sparing effect and result in minimal scarring. ECT may be a suitable alternative therapy for the treatment of basal cell carcinoma, local or regional recurrent melanoma, and other skin cancers.

Surgical resection and adjuvant radiation therapy are standard therapy for soft tissue sarcomas. When the tumor approximates bone, periosteal excision may be necessary. It was hypothesized that periosteal stripping and radiation therapy would increase the rate of pathologic fracture. ⋯ Periosteal stripping and radiation therapy places the femur at high risk of pathologic fractures, especially for female patients and patients undergoing chemotherapy. When practical, the combination of periosteal stripping and radiation should be avoided.

Antibacterial prophylaxis with quinolone antibiotics has resulted in an increase in streptococcal infections among bone marrow transplantation (BMT) recipients with myelosuppression. Oral ulceration (mucositis), which frequently occurs as a consequence of chemotherapy, has been implicated as a significant portal of entry for streptococci. The objectives of this study were to confirm the correlation between mucositis and streptococcal bacteremia, determine the risk associated with this correlation, and evaluate the impact of mucositis and streptococcal bacteremia on hospital course and costs associated with autologous BMT. ⋯ Oral ulcerative mucositis is a significant, common, and important risk factor for alpha-hemolytic streptococcal bacteremia in BMT recipients with myelosuppression; it results in longer hospital stay and increased costs.
