It is mainly found in female patients, the right breast in more frequently involved. The majority of PBL are diagnosed by biopsy or post- operative pathological findings. The combined therapy regimen, the main part of which is CHOP chemotherapy, is the main stream. Radical surgery is to be avoided.展开更多

After analyzing 12 randomized controlled trials(RCTs), we discuss the key issues of surgery in the management of resectable EC. Along with chemoradiotherapy, NCRT is recommended for patients with squamous cell carcinoma(SCC) and adenocarcinoma(AC), and most chemotherapy regimens are based on cisplatin, fluorouracil(FU), or both(CF). However, taxane-based schedules or additional studies, together with newer chemotherapies, are warranted. In nine clinical trials, post-operative complications were similar without significant differences between two treatment groups. In-hospital mortality was significantly different in only 1 out of 10 trials. Half of the randomized trials that compare NCRT with surgery in EC demonstrate an increase in overall survival or disease-free survival. NCRT offers a great opportunity for margin negative resection, decreased disease stage, and improved loco-regional control. However, NCRT does not affect the quality of life when combined with esophagectomy. Future trials should focus on the identification of optimum regimens and selection of patients who are most likely to benefit from specific treatment options.展开更多
