Resection of synchronous liver metastases from colorectal cancer 总被引:13,自引:0,他引:13
Background: The prognosis for patients with liver metastasesfrom colorectal cancer is still poor. Thus, patient selectionfor hepatic resection is essential to improve the poor resultsof the procedure. Some reports have shown that the prognosisfor patients with synchronous liver metastases is worse thanthat for those with metachronous liver metastases. Therefore,determination of the factors that influence outcome after resectionof synchronous liver metastases is more important than withmetachronous liver metastasis. Method: We studied patients who had been followed for more than5 years after undergoing resection of synchronous liver metastasesfrom colorectal cancer. Results: Among the 12 prognostic factors studied (age, gender,adjuvant chemotherapy, tumor site, CEA level, tumor differentiation,tumor size, regional lymph node metastatic status, distributionof liver metastases, number of liver metastases, tumor sizeand pathological margin), regional lymph node metastatic statusand pathological margin were significant prognostic factorsby univariate analysis (p = 0.0002 and 0.005, respectively).Regional lymph node metastatic status was a significant prognosticfactor by multivariate analysis (p = 0.031). The survival curveof patients with six or more regional lymph node metastaseswas similar to that of patients with non-resectable liver metastasis. Conclusion: The resection of synchronous liver metastases inpatients with six or more regional lymph node metastases isrelatively contraindicated. For these patients, other treatmentmodalities should be considered.

BACKGROUND AND PURPOSE: Hepatic arterial infusion chemotherapy for unresectable liver metastases of colorectal cancer is generally indicated to patients without extra hepatic lesions. This study was performed to examine the status of hepatic lymph node metastasis as an extra hepatic lesion in patients with synchronous multiple liver metastases of colorectal cancer. PATIENTS AND METHODS: A total of 111 hepatic lymph nodes were removed from 33 patients with synchronous liver metastases of colorectal cancer during resection of the primary tumor at the D2- or D3- level. The frequency of hepatic lymph node metastases and factors predictive for hepatic lymph node metastasis were examined. RESULTS: Hepatic lymph node metastasis was detected in nine patients (27%): The sites were classified into three categories: (1) along the hepatic arteries in three, (2) in the hepato-duodenal ligament except the peri-hepatic arterial region in three, and (3) both in three. The serum level of CEA (p = 0.02), CA19-9 (p = 0.05), and the rate of lymph node metastasis of the primary lesion (p = 0.08) were higher or tended to be higher in patients with hepatic lymph node metastases than in those without. There was no significant relationship between the involvement of hepatic lymph nodes and the other clinicopathologic factors examined. CONCLUSION: We should note the frequency of hepatic lymph node metastasis in the treatment of unresectable liver metastases of colorectal cancer. 相似文献

A multifactorial analysis was used to identify the dominant prognostic variables predicting survival rates of 175 patients with hepatic metastases from colorectal carcinoma. Seven of 22 parameters examined simultaneously were found to independently influence the median survival rate in these patients: (1) elevated alkaline phosphatase (p = 0.0004), (2) elevated serum bilirubin level (p = 0.0005), (3) location of hepatic metastases (unilateral or bilateral, p = 0.0022), (4) number of metastatic nodes involved (0, 1-5, greater than 5; p = 0.0148), (5) depressed serum albumin (p = 0.0217), (6) whether or not the primary colorectal tumor was resected (p = 0.0013), and (7) chemotherapy (given or withheld, p = 0.0439). The prothrombin time, serum lactic dehydrogenase, and the number of hepatic metastases also correlated with survival, but they did not independently predict survival rates after other more dominant factors were accounted for. A mathematical equation for predicting an individual patient's clinical course once they developed hepatic metastases was derived from this statistical analysis. In addition, a simple and clinically useful guide for predicting outcome was developed that integrated the two most important risk factors, alkaline phosphatase and bilirubin. 相似文献

Liver resection has been recognized as the best treatment for patients with colorectal liver metastases, but as a curative resection for multiple and bilobar colorectal liver metastases (MBCLM) it is definitely less effective. We clarify predictors of survival for unresectable MBCLM. Potential predictors of overall survival, and the correlation between tumor marker and survival were evaluated for patients with synchronous unresectable MBCLM, including 6 rectal and 17 colon cancers. In univariate analysis, survival in patients with the following parameters were longer than those without them: number of liver metastases (=10), without lung metastasis and peritoneal invasion, and with a <1.0 ratio of postoperative CEA/preoperative CEA. In multivariate analysis, the numbers of liver metastases (>10) and a >1.0 ratio of postoperative CEA/preoperative CEA were factors of poor prognosis, and patients with two such factors had an even worse prognosis. There was a tendency for correlation between the ratio of postoperative CEA/pre-operative CEA and survival (R=-0.492, P=0.053; y=17.388-3.733x). Thus, we clarified some of the predictors of survival for MBCLM, and the usefulness of serum CEA. 相似文献

乳腺癌肝转移的临床病程与预后分析 总被引:2,自引:0,他引:2
目的 探讨乳腺癌肝转移的临床病程、治疗效果及预后因素。方法 采用SPSS 11.5统计软件对152例乳腺癌肝转移患者的生存及预后因素进行回顾性分析。结果 全组中位无病生存期(DFS)为21个月,转移后中位生存期(MSR)为16个月,中位至疾病进展时间(TTP)为7.4个月。肝转移后一线化疗的有效率为54.5%,高于介入治疗(37.7%,P=0.039)。含紫杉类方案化疗组的有效率为63.3%,高于不含紫杉类方案化疗组(40.O%,P=0.04);含紫杉类方案化疗组的TTP为10个月,亦高于不含紫杉类方案化疗组(7个月,P=0.048)。无论介入治疗(TACE),还是化疗,治疗有效者的MSR(18个月)均长于无效者(14个月,P=0.002)。对于单发肝转移瘤患者,单纯介入治疗的MSR(30个月)长于单纯化疗(16个月,P=0.0052);对于多发肝转移瘤患者,单纯介入治疗与单纯化疗的MSR差异无统计学意义。原发肿瘤大小、腋窝淋巴结转移数、雌激素受体状态、肝转移后转氨酶异常程度、肝转移灶大小是影响预后的重要因素。结论 有效的化疗(尤其是含紫杉类方案化疗)和介入治疗能明显改善乳腺癌肝转移患者的预后。 相似文献

BackgroundIn patients with asymptomatic colorectal cancer with irresectable metastatic disease, the optimal treatment strategy remains controversial. Resection of the primary tumor followed by chemotherapy when possible versus systemic chemotherapy followed by resection of the primary tumor when necessary are compared in this systematic review.Patients and methodsSeven studies reported series of patients with asymptomatic stage IV colorectal cancer and compared first-line chemotherapy with surgery for the primary tumor (n = 850 patients). Primary outcome measure was the complication rate related to the primary tumor in situ in patients receiving first-line systemic chemotherapy.ResultsWhen leaving the primary tumor in situ, the mean complications were intestinal obstruction in 13.9% [95% confidence interval (CI) 9.6% to 18.8%] and hemorrhage in only 3.0% (95% CI 0.95% to 6.0%) of the patients. After resection, the overall postoperative morbidity ranged from 18.8% to 47.0%.ConclusionsFor patients with stage IV colorectal cancer, resection of the asymptomatic primary tumor provides only minimal palliative benefit, can give rise to major morbidity and mortality and therefore potentially delays beneficial systemic chemotherapy. When presenting with asymptomatic disease, initial chemotherapy should be started and resection of the primary tumor should be reserved for the small portion of patients who develop major complications from the primary tumor. 相似文献
