术前TAGM联合弹簧圈门静脉栓塞根治肝门胆管癌1例报告

正右侧侵犯为主的肝门胆管癌根治术多需要联合右半肝切除,可能会导致术后肝衰竭。近年来,计划性肝切除的策略备受关注,采用门静脉栓塞(portal vein embolization,PVE)的介入技术能诱导未来残余肝(future liver remnant,FLR)术前增生、降低肝衰风险~([1-3])。使用三丙烯酸酯明胶微球(tris-acryl gelatin microspheres,TAGM)作为末梢栓塞剂,联合近侧弹簧圈的PVE在国内鲜有报道。笔者单位1例尝试采用此技术治疗1例。报告如下。

??Objective    To explore the relationship between chronic periodontitis and cytokine interleukin-8 ??IL-8?? by literature review. Methods    The CNKI??Wanfang database??PubMed retrieval platform and Embase database were searched by computer. The research papers on the level of interleukin-8 in chronic periodontitis were collected. The retrieval time was up to 2016??screen literature according to the inclusion and exclusion criteria??use Stata12.0 software for meta analysis. Results    The level of IL-8 in gingival crevicular fluid in patients with chronic periodontitis was significantly higher than that in normal controls??P??0.05??. In the Asian population?? the level of IL-8 in gingival crevicular fluid in patients with chronic periodontitis was higher than that in normal controls??P??0.05??. In the western population??there was no difference in the level of IL-8 in gingival crevicular fluid between patients with chronic periodontitis and normal controls??P??0.05??. Conclusion    There is a significant difference in chemokines interleukin-8 between patients with chronic periodontitis and normal controls in the Asian population. Chemokines interleukin-8 may increase the risk of chronic periodontitis.

Abstract Objective To investigate the efficacy of laparoscopic hyperthermic intraperitoneal chemotherapy (HIPEC) combined intraperitoneal and systemic chemotherapy in gastric cancer patients with peritoneal metastasis. Methods A gastric cancer patient whose peritoneal cancer index was 39 during laparoscopic exploration was admitted at Peking University Cancer Hospital Gastrointestinal Center. The patient received laparoscopic HIPEC with docetaxel, followed by 6 courses of intraperitoneal and intravenous PTX??along with S-1 orally. Results CT scan showed distinct response during post-treatment evaluation. A second look by laparoscopy was suggested by MDT. No tumor cell was found in the lavage fluid through abdominocentesis and no metastasis can be seen by laparoscopic exploration. Then total gastrectomy plus D2 minus No.10 lymph node dissection was performed. The patient recovered smoothly after surgery. The pathology confirmed a ypT3N2M1, moderate to poor-differentiated adenocarcinoma, from gastric antrum to body. By September 2017, the patient was still in postoperative treatment. Conclusion Laparoscopic HIPEC combined with intraperitoneal and systemic chemotherapy showed effective interim results in gastric cancer peritoneal metastasis conversion therapy and is deserved for further researches.

??Value of preoperative lymphoscintigraphy in sentinel lymph node biopsy of breast cancer SUN Xiao*, LIU Juan-juan, WANG Yong-sheng, et al. *Breast Cancer Center, Shandong Cancer Hospital, Jinan 250117, China

Abstract Objectives Background Although preoperative lymphoscintigraphy for sentinel lymph nodes biopsy (SLNB) in breast cancer patients is undergone commonly, its clinical significance remains controversial. Methods Firstly, a database containing 716 consecutive breast cancer patients who received preoperative lymphoscintigraphy before SLNB was retrospectively analyzed. Secondly, 565 consecutive breast cancer patients were prospectively randomized into groups with or without preoperative lymphoscintigraphy before SLNB. Results In the retrospective study, sentinel lymph nodes (SLNs) were well imaged by lymphoscintigraphy in 86.6% patients, and negative lymphoscintigraphy results were associated with axillary node metastases. Failure of identification of SLNs by isotope alone was associated with whether axillary hot spot was imaged by lymphoscintigram (P<0.001). There were no significant differences in the false negative rate (P=0.731) of SLNB by isotope alone, in the identification rate (P=0.174) and the false negative rate (P=0.947) of SLNB by combination of dye and isotope between patients who had axillary hot spot in lymphoscintigram and those who had not. In the prospective study, 290 patients were randomized into the group with preoperative lymphoscintigraphy (82.1% patients were well imaged by lymphoscintigraphy) and 275 patients without. There were no significant differences between two groups in the identification rate (P=0.757) and the false negative rate (P=1.00) of SLNB by isotope alone, also in the identification rate (P=1.00) and the false negative rate (P=1.00) of SLNB by combination of dye and isotope. Conclusion Preoperative lymphoscintigraphy could not improve the identification rate and reduce the false negative rate of SLNB in breast cancer patients, and it is not a prerequisite for SLNB.
