Abstract
BACKGROUND New chemotherapy schemes have allowed for a better radiological response of unresectable colorectal liver metastases, leading to an interesting scenario known as a complete radiological response. The aim of this study was to review the current management of missing liver metastases (MLM) from the liver surgeon's point of view. METHODS A systematic search was conducted on all publications of PubMed and Embase between 2003 and 2018. Meta-analysis was performed on MLM resected/unresected. Residual tumor or regrowth and relapse-free survival were used as evaluation indices. RESULTS After literature search, 18 original articles were included for analysis. The predictive factors for MLM are type and duration of chemotherapy and size and number of lesions. Magnetic resonance is the most sensitive preoperative technique. Regarding clinical management, liver surgery is deemed the fundamental pillar in the therapeutic strategy of these patients. Meta-analysis due to data heterogeneity was inconclusive. CONCLUSIONS Depending on the clinical context, MLM monitoring appears to be a valid therapeutic alternative. Nevertheless, prospective randomized clinical studies are needed.

ACTA ACUST UNITED AC 2021; 34:e1578. [PMID: 34133525 PMCID: PMC8195463 DOI: 10.1590/0102-672020210001e1578] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 10/09/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND About 50% of the patients with colorectal adenocarcinoma will present with liver metastasis and 20% are synchronic. Liver resection is associated with improvement in survival in comparison to chemotherapy alone. AIM To analyze the overall survival in patients submitted to liver resection of colorectal cancer metastasis and prognostic factors related to the primary and secondary tumors. METHODS A retrospective analysis of a prospectively maintained database regarding demographic, primary tumor and liver metastasis characteristics. RESULTS There were 84 liver resections due to colorectal cancer metastasis in the period. The 5-year disease-free and overall survivals were 27.5% and 48.8% respectively. The statistically significant factors for survival were tumor grade (p=0.050), lymphovascular invasion (p=0.021), synchronous metastasis (p=0.020), as well as number (p=0.004), bilobar distribution (p=0.019) and diameter of the liver metastasis over 50 mm (p=0.027). Remained as independent negative predictive factors: lymphovascular invasion (HR=2.7; CI 95% 1.106-6.768; p=0.029), synchronous metastasis (HR=2.8; CI 95% 1.069-7.365; p=0.036) and four or more liver metastasis (HR=1.7; CI 95% 1.046-2.967; p=0.033). CONCLUSION The resection of liver metastasis of colorectal adenocarcinoma leads to good survival rates. Lymphovascular invasion was the single prognostic factor related to the primary tumor. Synchronous disease and four or more metastasis were the most significant factors related to the secondary tumor.

Ma R, Li T. Conversion therapy combined with individualized surgical treatment strategy improves survival in patients with colorectal cancer liver metastases. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2021; 14:314-321. [PMID: 33786148 PMCID: PMC7994140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Accepted: 01/21/2021] [Indexed: 06/12/2023]
Abstract
OBJECTIVE To explore surgical treatment strategies for patients with liver metastases from colorectal cancer (CRLM), and analyze the prognosis and influencing factors. METHODS The clinical data of 156 inpatients with CRLM admitted to our hospital from January 2009 to June 2019 were retrospectively analyzed. Patients were divided into initially resectable group (80 cases) and initially unresectable group (76 cases). For patients with initially unresectable CRLM, conversion therapy (chemotherapy plus targeted therapy) combined with individualized surgical treatment strategy was used. The individualized surgical treatment strategy mainly included hepatectomy combined with ablation. Portal vein ligation and staged resection were adopted according to the patients' specific conditions. All patients were followed up until death. The Kaplan-Meier method and Log-rank test were used for survival analysis. RESULTS Median overall survival (OS) time of patients in the initially resectable group and initially unresectable group were 36 months and 17 months, respectively (P = 0.001). Median OS time of 24 patients who underwent surgical resection after successful conversion therapy was significantly longer than that of 52 patients with unsuccessful conversion therapy (20 months versus 15 months, respectively, P = 0.034). Univariate analysis showed that a maximum diameter of liver metastases < 6 cm and a number of metastases ≤ 4 were independent factors associated with successful conversion therapy. According to patients' specific conditions, 6 cases accepted hepatectomy combined with ablation, and 1 case accepted portal vein ligation and staged resection. CONCLUSION Treatment of patients with CRLM should follow the principles of standardization and individualization. For patients with initially unresectable CRLM, successful conversion therapy should be pursued whenever possible. The maximum size and number of liver metastases were significantly associated with successful conversion therapy. Surgical resection-based comprehensive treatment is key.

Abstract
ABSTRACT BACKGROUND: Liver metastases from colorectal cancer are an important public health problem due to the increasing incidence of colorectal cancer worldwide. Synchronous colorectal liver metastasis has been associated with worse survival, but this prognosis is controversial. OBJECTIVE: The objective of this study was to evaluate the recurrence-free survival and overall survival between groups of patients with metachronous and synchronous colorectal hepatic metastasis. METHODS: This was a retrospective analysis of medical records of patients with colorectal liver metastases seen from 2013 to 2016, divided into a metachronous and a synchronous group. The Cox regression model and the Kaplan-Meier method with log-rank test were used to compare survival between groups. RESULTS: The mean recurrence-free survival was 9.75 months and 50% at 1 year in the metachronous group and 19.73 months and 63.3% at 1 year in the synchronous group. The mean overall survival was 20.00 months and 6.2% at 3 years in the metachronous group and 30.39 months and 31.6% at 3 years in the synchronous group. Patients with metachronous hepatic metastasis presented worse overall survival in multivariate analysis. The use of biological drugs combined with chemotherapy was related to the best overall survival prognosis. CONCLUSION: Metachronous colorectal hepatic metastasis was associated with a worse prognosis for overall survival. There was no difference in recurrence-free survival between metachronous and synchronous metastases.

Abstract
BACKGROUND AND OBJECTIVES Liver metastases are indicators of advanced disease in patients with colorectal cancer. Liver resection offers the best possibility of long-term survival. Surgical strategies have evolved in complexity in order to offer resection to a greater number of patients, requiring specialized multidisciplinary care. The current paper focused on analyzing outcomes of patients treated after the development of a dedicated cancer center in our institution. METHODS Patients operated on for CLM from our databank were paired through propensity score matching (PSM), and the initial experience of surgery for CLM was compared with the treatment performed after specialized multidisciplinary management. The demographic, oncological, and surgical features were analyzed between groups. RESULTS Overall, 355 hepatectomies were performed in 336 patients. Patients operated on during the second era of had greater use of preoperative chemotherapy (P < 0.001) as well as exposure to more effective oxaliplatin-based regimens (P < 0.001). Surgical management also changed, with minor (P = 0.002) and non-anatomic (P = 0.006) resections preferred over major operations. We also noted an increased number of minimally invasive resections (P < 0.001). CONCLUSION Treatment in a multidisciplinary cancer center led to changes in oncological and surgical management. Perioperative chemotherapy was frequently employed, and surgeons adopted a conservative approach to liver parenchyma.

Abstract
The aim of this meta-analysis was to compare the efficacy and safety of simultaneous resections between the minimally invasive approach (MIA) and the open approach (OA) for patients with colorectal cancer (CRC) and synchronous colorectal liver metastases (SCRLM). A systematic search was conducted in the Cochrane Library, PubMed, EMBASE and Ovid databases (until May 5, 2016). Studies comparing the perioperative results and long-term outcomes for patients undergoing simultaneous CRC and SCRLM resections between the two approaches were evaluated. Six studies were identified, which included 164 minimally invasive and 213 open simultaneous resections of CRC and SCRLM. MIA was associated with lesser surgical blood loss (mean difference = -155.85 mL; 95% confidence interval: -305.64 to -6.06, P = 0.04) and shorter length of postoperative stay (mean difference = -3.16 days; 95% confidence interval: -4.00 to -2.31, P < 0.00001.). The other perioperative results, including operating time, operative blood transfusion, intestinal function recovery time, and postoperative complications, did not differ significantly. No significant difference in the disease-free survival and overall survival rates between the two approaches was observed. In conclusion, compared with the OA, the MIA for simultaneous CRC and SCRLM resections is safe and effective for the treatment of SCRLM with lesser surgical blood loss and shorter length of postoperative stay. The MIA may be an alternative to the OA for simultaneous CRC and SCRLM resections for appropriately selected patients with resectable SCRLM.

Abstract
PURPOSE To investigate the efficacy and safety of laparoscopic simultaneous resections of colorectal cancer and synchronous colorectal liver metastases (SCRLM), relative to open surgery. METHODS Between 1 January 2009 and 20 April 2014, 20 of 25 patients who underwent laparoscopic simultaneous colorectal cancer and SCRLM resections were matched with 20 of 29 patients who underwent an open approach, based on prognostic propensity scores. Perioperative results and survival outcomes were compared. RESULTS The laparoscopic and open groups were comparable in demographics, cancer characteristics, surgery characteristics, and chemotherapy treatment. No postoperative mortality occurred in either group. The estimated blood loss and postoperative stay were significantly greater in the open group than in the laparoscopic group (all, p < .05). All other perioperative results and postoperative complications were similar between the two groups, as well as three-year overall and disease-free survival rates. CONCLUSIONS The postoperative complications and survival rates of patients given laparoscopic simultaneous colorectal cancer and SCRLM resections were similar to those treated with an open approach, but with greater short-term benefits. Laparoscopy in this setting by an experienced surgical team appears safe and effective, and is a feasible alternative to an open approach for selected patients.
