ObjectiveTo understand the latest progress of conversion therapies on increasing surgical resection rate of patients with liver metastasis from colorectal carcinoma, evaluate the clinical value of prognostic evaluation model in surgical resection of patients with liver metastasis from colorectal carcinoma, further offer guidance in comprehensive treatment to control disease and improve the quality of life. MethodsThe literatures about new progress in surgical treatment of liver metastasis from colorectal carcinoma at domestic and abroad were reviewed, including the indication of operation, prognostic evaluation model, and how to increase the resection rate for liver metastasis from colorectal carcinoma patients with conversion therapies. ResultsPart of patients with liver metastasis from colorectal carcinoma could get surgeries after accepting positive conversion therapies.For the patients with liver metastases from colorectal carcinoma did not accepted surgeries all the way, it was a safe and effective treatment method by different conversion therapies such as neoadjuvant chemotherapy, molecular targeted therapy, transcatheter arterial chemoembolization, radiofrequency ablation, and so on, and it could improve the quality of life and prolong the survival time. ConclusionsDoctors should pay attention to conversion therapies of patients with liver metastasis from colorectal carcinoma, and promote the usage of the prognostic evaluation model in liver metastasis from colorectal carcinoma.
ObjectiveTo understand the latest progress of transcatheter arterial chemoembolization (TACE)-based combination therapies for unresectable liver metastasis from colorectal carcinoma, and to explore the safe and effective combination therapies in order to controlling the rapid progress of disease and improving the quality of life of patients. MethodsThe literatures about TACE-based combination therapies of liver metastasis from colorectal carcinoma and the latest advance in researches of this field at home and abroad were collected, and the application of combination therapies, the advantages and features of the combined treatments were reviewed. ResultsTACE was a safe and effective therapeutic modality in treating primary liver cancer or secondary liver cancer.Compared with a single treatment, TACE-based combination therapies had distinct advantages to patients with liver metastasis from colorectal carcinoma not only improved the quality of life but also prolonged the survival time.With the emerging of various kinds of new drugs and the rapid development of a variety of interventional treatments, it could bring long-term survival benifit for patients with liver metastasis from colorectal carcinoma. ConclusionsDoctors should pay attention to the combined treatments of patients with liver metastasis from colorectal carcinoma, improve the knowledge of personalized medication about advanced tumors and actively promote more usage of combination therapies.
ObjectiveBy analyzing the correlation between the clinicopathological features of patients with colorectal liver metastases (CRLM) and their postoperative survival, this study is aimed to identify new and accurate prognostic indicators on the prognoses to provide a reference of the treatment strategy selection for patients with CRLM. MethodsThe clinical data of 233 patients with CRLM who received operation treatments in the Eastern Hepatobiliary Hospital of the Second Military Medical University from January 2006 to December 2009 were retrospectively investigated, and their clinicopathological features, as well as their prognosis were analyzed. The survival curve was drawn by Kaplan-Meier method, and the survival rates were analyzed by log-rank test. Parametric survival analysis was used to identify predictors of cancer-specific survival. ResultsThe median survival time after cancer resection was 37.0 months, with cumulative 1-year, 3-year, and 5-year survival rates of 93.0%, 61.0%, and 17.0%, respectively. The median survival time, with cumulative 3-year, and 5-year survival rates of patients who had received radical operations was better than the others who received palliative operations:40.53 months vs 27.20 months, 59.0% vs 29.0%, and 20.0% vs 0(P < 0.05), respectively. In overall surviva, the results of univariate analysis showed that 13 factors, including surgical method, the first relapse after liver metastasis resection, the number of liver metastases, surgical margin, other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, whether any chronic liver disease was associ-ated, preoperative serum CEA level, preoperative serum CA19-9 leve, the position of the liver metastases, whether the liver metastasis capsule was complete, TNM stagethe of primary cancer, whether the liver metastasis was simultaneous liver metastases, and the maximum diameter of the liver metastases, were closely related to the clinicopathological features associated with prognosis and the differences were statistically significant (P < 0.05). The results of multivariate survival analysis demonstrated that received palliative operations, simultaneous liver metastases, there were other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, liver metastases without a complete capsule, the number of liver metastases appeared as multiple and widedistribution, unassociated chronic liver disease of the patients, the maximum diameter of the liver metastases>3 cm, were the independent risk factors affecting the postoperative survival of the patients with CRLM (P < 0.05). ConclusionsIt is important for long-term survival of patients with CRLM who were received operations. Received palliative operations, simultaneous liver metastases, there were other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, liver metastases without a complete capsule, the number of liver metastases appeared as multiple and widedistribution, unassociated chronic liver disease of the patients, the maximum diameter of the liver metastases>3 cm, were the independent risk factors affecting the postoperative survival of the patients with CRLM.
