Objective:To assess the safety and efficacy of induction chemotherapy with cisplatin and docetaxel followed by radia-tion concurrent with weekly cisplatin for unresectable, locally advanced esophageal cancer. Methods: Thirty-three patients with T3N0M0 to T4N2M0 thoracic esophageal squamous cell carcinoma without celiac lymph node metastasis were included in the study. They were treated with cisplatin (75 mg/m2 d1, d22) and docetaxel (75 mg/m2 d1, d22) neoadjuvant chemotherapy followed by three-dimensional conformal radiotherapy (60Gy/30F/6w) concurrent with cisplatin (30 mg/m2 d1, 8, 15, 22, 29, 36 from the beginning of radiation). Results:Grade 4 hematological toxicities were observed in 13.33%(4/33) of the patients after the neoadjuvant chemother-apy. No grade 3 or above hepatic or renal toxicities were found. During concurrent chemoradiation, the highest grade 3 hematological toxicities were observed in the erythrocyte, granulocyte, and macrophage at 21.21%(7/33), 15.15%(5/33), and 3.01%(1/33), respec-tively. No grade 2 or above hepatic or renal toxicities were observed. Grade 3 radiation esophagitis was observed in 9.1%(3/33) of the patients, whereas grade 3 and above radiation esophagitis or grade 1 and above acute radiation pneumonitis did not occur. The evalua-tion results after treatment completion were 84.85%(28/33), 12.12%(4/33), and 3.03%(1/33) for CR+PR, SD, and PD , respectively. Two months after treatment completion, the results changed to 75.76%(25/33), 9.10%(3/33), and 15.15%(5/33), respectively. Overall, 15 patients died. The one-year survival rate was 66.4%. Local failure was approximately 46.67%(7/15), whereas the local+distant fail-ure was approximately 26.67%(4/15). Therefore, local failure is the main pattern of failure in esophageal cancer. Conclusion:The re-sults indicate that neoadjuvant chemotherapy with cisplatin and docetaxel followed by radiotherapy concurrent with weekly cisplatin for locally advanced esophageal cancer is safe. Local failure remains the main pattern of failure in esophageal cancer.

Objective To investigate the preventive effect of endoclips and endoloops on postpolypectomy bleeding of large colorectal polyps.Methods Data of patients,who underwent polypectomy during January 2013 to March 2016,were retrospectively collected.The diameters of all polyps were more than 10 mm.Cases were divided into 4 groups.Before large pedunculated (with thick stalks) polyps were resected,endoclips were used to ligate the pedicles of polyps in Group A,and endoloops were used in Group B.After large sessile and pedunculated (without thick stalks) polyps were resected,endoclips were used to close the incision of polypectomy in Group C,but not in Group D.The immediate and delayed postpolypectomy bleeding rate and clinicopathologic features were studied.Articles about endoclip or endoloop on preventing post-polypectomy bleeding in PubMed in last five years were searched and analyzed.Results A total of 2 006 polyps were included.The immediate bleeding rate was 3.4% (5/147) and 3.8% (5/132) of Group A and B,respectively.The delayed bleeding rate was 6.1% (9/147) and 7.6% (10/132) of Group A and B,respectively.The delayed bleeding rate of Group C and D was 3.2% (28/888) and 1.9% (16/839),respectively.None of the bleeding cases needed a surgical operation.And no perforation occurred.Six articles were included for analysis.Most of articles revealed that endoclip and endoloop were effective tools in prevention of post-polypectomy bleeding.Conclusion Endoclips and endoloops are useful to prevent bleeding after resection of large pedunculated (with thick stalks) polyps.For large sessile and pedunculated (without thick stalks) polyps (diameter> 10 mm),the effect of endoclips to prevent postpolypectomy bleeding still needs further discussion.
