Objective To evaluate the prognostic value of lateral pelvic lymph node metastasis on low rectal cancer. Methods One hundred and seventy-six patients with low rectal cancer who underwent radical resection combined with lateral pelvic lymph node dissection between 1994 and 2005 were reviewed. The data of the cases was investigated to define the prognostic value of lateral pelvic lymph node metastasis on the patients. Results Lateral node metastasis occurred in 33 patients (18.8%), and 51.5% of the metastasis occurred in internal iliac nodes or nodes at middle rectal roots and 39.4% in obturator nodes. Age ≤40 years, infiltrative cancer, T3-4 tumor, upward lymph node metastasis were risk factors for lateral node metastasis in low rectal cancer (P < 0.05). The overall 5-year survival rate was 64.1%, and it was 94.1%, 79.1%, 42.1% for patients with TNM stage Ⅰ , Ⅱ , Ⅲ cancer, respectively. Tumor size, depth of infiltration, upward lymph node metastasis, lateral node metastasis was correlated significantly with prognosis (P < 0.05). The 5-year survival rate of the patients without lateral metastasis was 73.6%, which was significant higher than that of patients with lateral metastasis (21.4%, P <0.05). Conclusion Lateralpelvic lymph node metastasis is an important prognostic factor for low rectal cancer. 相似文献

Background
The lymph node ratio, defined as the ratio between the number of lymph node metastasis and the total number of lymph nodes examined, has been reported to be an important prognostic factor in other gastrointestinal carcinomas except middle and distal bile duct carcinomas.Methods
Between 1991 and 2004, 62 consecutive patients who underwent surgery for middle and distal bile duct carcinoma were retrospectively analyzed concerning prognostic factors.Results
The median number of lymph nodes examined was 12 (range 5 to 38). The overall 5-year survival rates of patients with lymph node ratio of 0, lymph node ratio of 0 to .2, and lymph node ratio >.2 were 62%, 41%, and 0%, respectively. A multivariate analysis revealed that a lymph node ratio >.2 and perineural invasion were independent predictive factors for survival.Conclusions
Lymph node ratio >.2 is an important factor to predict survival after resected middle and distal bile duct carcinoma. 相似文献13.

BACKGROUND: The presence or absence of lymph node metastases is known to be an important prognostic factor for patients with pancreatic cancer. Few studies have investigated the ratio of the number of lymph nodes harboring metastatic cancer to the total number of lymph nodes examined (lymph node ratio [LNR]) with regard to outcome after pancreaticoduodenectomy for ductal cancer of the pancreas. METHODS: Between 1995 and 2005, a total of 905 patients underwent pancreaticoduodenectomy for pancreatic adenocarcinoma. Demographics, operative data, number of lymph nodes evaluated, number of lymph nodes with metastatic carcinoma, LNR, pathologic margin status, and long-term survival were analyzed. RESULTS: There were 187 (20.7%) of the 905 patients who had negative peripancreatic lymph nodes (N0), whereas 718 (79.3%) of the 905 patients had lymph node metastases (N1). The median number of lymph nodes evaluated in the N0 group was 15 versus 18 in the N1 group (P = .12). At median follow-up of 24 months, the median survival for all patients was 17.4 months, and the 5-year actuarial survival rate was 16.1%. Patients with lymph node metastases had a shorter median overall survival (16.5 months) compared with patients with negative lymph nodes (25.3 months; P = .001). Compared with the total number of lymph nodes examined or total number of lymph node metastases, LNR was the most compelling predictor of survival. As the LNR increased, median overall survival decreased (LNR = 0, 25.3 months; LNR > 0 to 0.2, 21.7 months; LNR > 0.2 to 0.4, 15.3 months; LNR > 0.4, 12.2 months; P = .001). After adjusting for other factors associated with survival, LNR remained an independent predictor of overall survival (P < .001). CONCLUSIONS: After pancreaticoduodenectomy for adenocarcinoma of the pancreas, LNR was one of the most powerful predictors of survival. LNR should be considered when stratifying patients in future clinical trials. 相似文献

Purpose
The aims of this paper were to evaluate the clinical features of patients with primary duodenal adenocarcinoma and to address the prognostic relevance of different surgical and pathological variables after potentially curative pancreaticoduodenectomy.Methods
Patients with primary duodenal adenocarcinoma observed from 2000 through 2009 were identified from a single-institution electronic database. Univariate and multivariate analyses were performed to identify factors associated with survival.Results
The study population consisted of 37 patients. Of these, 25 underwent pancreaticoduodenectomy, while the remaining 12 were not amenable to resection and underwent bypass operations or were given best supportive care. Overall survival after radical resection (R0) was significantly longer than after palliative surgery (180 versus 35 months, p?=?0.013). On multivariate analysis, tumor grade (hazard ratio (HR)?=?1.345, 95% CI?=?1.28–1.91, p?=?0.03) and the occurrence of postoperative or abdominal complications (HR?=?1.781, 95% CI?=?1.10–2.89, p?=?0.037; HR?=?1.878, 95% CI?=?1.21–3.08, p?=?0.029) were found to be significant prognostic factors for survival in patients undergoing potentially curative resection. In particular, median survival was 180 months in patients with an uneventful postoperative course and 52 months in those with abdominal complications. The 5-year overall survival rates were 100 and 60 %, respectively.Conclusions
According to the present findings, the development of postoperative complications may be an additional prognostic factor after potentially curative pancreaticoduodenectomy for primary duodenal adenocarcinoma. This emphasizes the need for centralization to high-volume centers where an appropriate postoperative care can be delivered. 相似文献15.

Background
The aim of this study was to investigate the prognostic value of metastatic lymph node (LN) ratio (LNR) compared with pathologic node (pN) category.Methods
Three hundred ninety-nine patients with gastric cancer with R0 resection were reviewed. LNR, pN, and the number of retrieved LNs were evaluated in node-positive groups with ≥15 or <15 LNs resected and a node-negative group, respectively, by univariate and multivariate analyses. Associations of pN and LNR with the number of retrieved LNs were determined using Spearman's rank correlation test.Results
LNR and pN were correlated with overall survival. For the node-positive group with ≥15 LNs retrieved, pN and LNR were independent prognostic factors, with the hazard ratio higher for LNR; neither was correlated with the number of retrieved LNs. For the group with <15 LNs retrieved, LNR but not pN was an independent prognostic factor, with LNR uncorrelated with the number of LNs retrieved. For the node-negative group, the number of LNs retrieved retained an independent prognostic factor.Conclusions
LNR is an independent prognostic factor in node-positive patients with gastric cancer with R0 resection, and it is uninfluenced by the number of LNs retrieved. It may be superior to pN. 相似文献17.
