胸段食管癌切除术患者的预后分析

Objective To investigate the prognostic factors and influence of the number of lymph node metastases on survival and UICC-TNM classification in patients with thoracic esophageal cancer after curative resection. Methods From 1985 to 1990, 1224 patients were surgically treated for thoracic esophageal cancer. The patients who died within 30 days after operation were not included in this study. Fifteen factors possibly influencing survival of these patients were selected and analyzed. A multivariate analysis of these individual variables was performed by Cox proportional hazard model. According to the n, mher of lymph node metastases (0, 1 and ≥ 2), a new modification of the TNM classification was suggested: stage Ⅱ a (T2N0M0 and T3N0M0), stage Ⅱb [T1N1M0 and T2N1 (1) M0], stage Ⅲ a [T2N1 (2)M0 and T3N1 (1)M0] and stage Ⅲ b [T3N1 (2)M0 and T4NanyMO]. Results According to multivariate analysis, lymph node metastases, depth of invasion, location of tumor, histological classification and length of the tumor were of prognostic significance (P < 0.01). There was obvious correlation between the rate of lymph node metastasis and the depth of invasion, length of tumor and grade of differentiation. The 5-year survival rate of the patients with 0, 1 and ≥2 positive metastatic lymph nodes was 59.1%, 32.0% and 8.9%, respectively. The 5-year survival rate of the patients with stage T2N1M0 and stage T3N1M0 was significantly higher in those with only one lymph node involved than in those with two or more lymph nodes involved (43.1% vs. 18.0% and 28.0% vs. 9.6%, P<0.01). The 5-year survival rate of the modified stage Ⅱa, Ⅱb, Ⅲa and Ⅲb was56.5%, 43.9%, 25.6% and 11.1%, respectively, with a statistically significant difference among different stages (P < 0. 01). Conclusion The lymph node metastasis is the most important prognostic factor for thoracic esophageal cancer after resection. The major influencing factors of lymph node metastasis are the depth of invasion, length of tumor and grade of differentiation. Therefore, the lymphadenectomy along with esophngectomy and subsequently combined modality therapy against lymph node metastasis is necessary to improve the S-year survival rate. Our proposed new classification based on number of lymph node metastases (0, 1, ≥2 positive nodes) is more applicable because it can well reflect the correlation between lymph node metastasis and the survival, and provides evidence for the modification of the currently used UICC TNM staging system for surgically treated thoracic esophageal cancer.

miR-645靶向STING调控结直肠癌转移作用机制的研究

目的 本研究旨在探索miR-645能否通过靶向SING来影响结直肠癌转移,进一步探索其作用机制。方法 采用细胞实验和动物模型来研究miR-645在结直肠癌中的功能。我们使用实时定量聚合酶链反应（qPCR）技术检测了miR-645在结直肠癌细胞系和组织样本中的表达水平。结果 发现miR-645在结直肠癌组织中高度表达,并与肿瘤的恶性特征相关。miR-645过表达显著促进了结直肠癌细胞的迁移和侵袭能力,而miR-645沉默则具有相反的效果。进一步的研究揭示了miR-645通过抑制STING蛋白的表达来促进结直肠癌的转移过程。结论 本研究结果表明,miR-645通过靶向STING调控结直肠癌转移。miR-645的上调与结直肠癌细胞的迁移和侵袭能力增强相关,同时也与肿瘤的恶性程度有关。这一研究结果有助于深入了解结直肠癌转移的分子机制,并为miR-645作为潜在治疗靶点提供了依据。
