目的 分析胸段食管癌二野淋巴结清扫术后局部复发规律,为术后放疗提供帮助.方法 搜集本科2004-2009年收治的134例胸段食管鳞癌术后局部复发患者的临床资料,依据放疗前定位CT分析复发类型及各区域淋巴结转移情况.结果 食管癌术后淋巴结转移占94.0%,吻合口复发占9.7%,食管原瘤床复发占3.7%.126例淋巴结转移患者中纵隔、锁骨上、腹部的分别占80.2%、43.7%、13.5%(χ2=113.15,P=0.000).淋巴结转移上纵隔占73.8%,左喉返神经区(1L区、2L区、4L区、5区)占38.9%,右喉返神经区(1R区)占43.7%,隆突下占34.1%,奇静脉占15.1%,锁骨上占43.7%[右锁骨上多于左锁骨上(31.7%和16.7%;χ2=7.81,P=0.005)].结论 淋巴结转移是胸段食管癌术后局部复发最主要的类型,原瘤床和吻合口复发少见.锁骨上、喉返神经区、奇静脉淋巴结及隆突下淋巴结是二野淋巴结清扫术后淋巴结转移的高发区.Abstract: Objective To investigate the local-regional recurrence in thoracic esophageal cancer after radical surgery including two-field lymph node dissection and provide evidence for postoperative radiotherapy. Methods We reviewed local-regional recurrence for 134 cases with esophageal squamous cell carcinoma after radical surgery from 2004 to 2009. Results In 134 cases, lymph node metastasis rate,anastomosis recurrence rate and tumor bed recurrence rate was 94. 0%, 9. 7% and 3.7%, respectively. As to the 126 cases with lymph node metastasis, significant difference was detected between mediastinal metastasis, supraclavicular metastasis and abdominal lymph node metastasis (80. 2%, 43.7% and 13.5%,respectively, χ2= 113. 15, P = 0. 000). Furthermore, the relative metastasis rate in upper mediastinum,middle mediastinum and the lower mediastinum was 73.8%, 39.7% and 1.6%, respectively, the difference was statistically significant ( χ2 = 139. 11, P = 0. 000 ). Significant difference was identified between right and left supraclavicular lymph node metastasis (31.7% vs 16. 7%, χ2= 7. 81, P = 0. 005 ).To confirm the analysis above,lymph node metastasis rate of left recurrent laryngeal nerve nodes, (including region 1L, 2L, 4L and 5) ,right recurrent laryngeal nerve nodes, azygos nodes, subcarinal nodes, and 2R region was 38.9%, 43.7%, 15.1%, 34.1% and 25.4%, respectively. Conclusions The main characteristics of local-regional recurrence may be lymph node metastasis for esophageal squamous cell carcinoma after radical surgery. On the contrary, tumor bed recurrence is rare. Dangerous regions include supraclavicular nodes, recurrent laryngeal nerve nodes, azygos nodes as well as subcarinal nodes. 相似文献

Axillary lymph node metastasis (ALNM) from esophageal cancer is rare. Its prognosis and effective treatments remain unknown. Between 1997 and 2005, esophagectomy was performed in 361 patients with esophageal cancer in our hospital. ALNM was identified in four patients (1.1%). All patients had left ALNM with ipsilateral left supraclavicular lymph node metastasis. In two patients ALNM developed after radical esophagectomy with regional lymphadenectomy and in the other two patients after chemoradiotherapy of primary lesions. Axillary lymphadenectomy with chemoradiotherapy was given to all patients. Median survival time and disease-free survival (DFS) after initial treatment for primary esophageal cancer were 30.5 months and 11.5 months, respectively. One patient, who had a small number of regional lymph node metastases (two lymph nodes) at esophagectomy and prolonged DFS (22 months) until axillary node recurrence, is still alive, 67 months after axillary lymphadenectomy. The other three patients, who had larger numbers of regional lymph node metastases (average, 8.3) and shorter DFS (average, 9.7 months), died of recurrence an average of 13.3 months after axillary lymphadenectomy. In conclusion, although ALNM is considered a type of distant organ metastasis, if it is a solitary recurrence, good survival may be obtained after appropriate loco-regional therapy. The number of metastatic regional lymph nodes at initial esophagectomy and the duration of DFS until axillary node recurrence can help to guide the decision whether aggressive treatments are warranted. 相似文献

Gastrectomy with lymph node (LN) dissection has been regarded as the standard surgery for gastric cancer (GC), however, the rational extent of lymphadenectomy remains controversial. Though gastrectomy with extended lymphadenectomy beyond D2 is classified as a non-standard gastrectomy, its clinical significance has been evaluated in many studies. Although hard evidence is lacking, D2 plus superior mesenteric vein (No. 14v) LN dissection is recommended when harbor metastasis to No. 6 nodes is suspected in the lower stomach, and dissection of splenic hilar (No. 10) LN can be performed for advanced GC invading the greater curvature of the upper stomach, and D2 plus posterior surface of the pancreatic head (No. 13) LN dissection may be an option in a potentially curative gastrectomy for cancer invading the duodenum. Prophylactic D2+ para-aortic nodal dissection (PAND) was not routinely recommended for advanced GC patients, but therapeutic D2 plus PAND may offer a chance of cure in selected patients, preoperative chemotherapy was considered as the standard treatment for GC with para-aortic node metastasis. There has been no consensus on the extent of lymphadenectomy for the adenocarcinoma of the esophagogastric junction (AEG) so far. The length of esophageal invasion can be used as a reference point for mediastinal LN metastases, and the distance from the esophagogastric junction to the distal end of the tumor is essential for determining the optimal extent of resection. The quality of lymphadenectomy may influence prognosis in GC patients. Both hospital volume and surgeon volume were important factors for the quality of radical gastrectomy. Centralization of GC surgery may be needed to improve prognosis. 相似文献

Background:
Increasing lymph node ratio (LNR) (ratio of metastatic lymph nodes to the total number of harvested lymph nodes) and extramural vascular invasion (EMVI) have been proposed as adverse prognostic indicators in colorectal cancer, although their use remains variable and controversial. The aim of the present study was to assess the prognostic value of LNR and EMVI in predicting survival for patients undergoing curative colon cancer resection.Methods:
Between 2006 and 2012, 922 patients underwent curative colon cancer resection. Surgical technique and pathological assessment did not change during the study period. Clinical and pathological data were collected from a prospectively maintained database. The primary outcome measure was overall survival and disease-free survival. LNR was separated into five categories based on three previously calculated cutoff values: LNR 0 (no lymph nodes involved), LNR 1 (ratio 0.01<0.17), LNR 2 (ratio 0.18–0.41), LNR 3 (ratio 0.42–0.69), and LNR 4 (ratio >0.70).Results:
Nine hundred and twenty-two patients underwent colon cancer resection. The median follow-up for survivors was 52.8 months (IQR 34.6–77.6). The median total number of lymph nodes harvested was 16 (IQR13-22). On multivariate analysis, both pN and LNR were strongly associated with overall and disease-free survival. Using the Akaike information criterion (AIC), LNR had greater prognostic value compared with pN. For overall survival, compared with patients in LNR category 0, hazard ratios (95% CI) for those in categories 1, 2, 3 and 4 were 1.37 (1.03,1.82), 2.37 (1.70,3.30), 2.40 (1.57,3.65) and 5.51 (3.16,9.58), respectively. For disease-free survival, patients had hazard ratios (95% CI) of 1.78 (1.25,2.52), 3.79 (2.56,5.61), 2.60 (1.50,4.48) and 4.76 (2.21,10.27), respectively. The presence of EMVI was a significant predictor of decreased overall and disease-free survival (P<0.001).Conclusions:
This study demonstrated, in the presence of high surgical, oncology and pathological standards, EMVI and increasing LNR were independent predictors of decreased overall and disease-free survival for patients undergoing curative colon cancer resection. LNR was superior to pN stage in predicting overall and disease-free survival. 相似文献19.
