Chan AKC, Siriwardena AK. Practical Implications of KRAS Mutation Status and Sidedness of Primary Tumour in Patients with Colorectal Cancer and Synchronous Liver Metastases: A Subset Analysis of the CoSMIC Study. Cancers (Basel) 2022; 14:cancers14194833. [PMID: 36230756 PMCID: PMC9563113 DOI: 10.3390/cancers14194833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/25/2022] [Accepted: 09/27/2022] [Indexed: 11/16/2022] Open
Abstract
Patients with colorectal cancer presenting with synchronous liver metastases have less favourable outcomes than those with primary-only disease. There is evidence of different genetic mutational signatures according to the sidedness of the primary tumour. KRAS mutations are key driver mutations in colorectal cancer progression. This post hoc analysis of the previously reported CoSMIC inception cohort explores the association between primary tumour sidedness and KRAS mutational status on the outcome of patients with colorectal cancer and synchronous liver metastases. Patients diagnosed with synchronous disease were recruited between April 2014 and March 2017 and, after exclusions, 83 patients undergoing colorectal primary KRAS mutation testing constituted the final study population. Data were collected prospectively on demographic profiles, treatment, and outcomes. Twenty-one patients (25%) had right-sided tumours and 62 (75%) had left-sided tumours, with 46 (55%) and 37 (45%) exhibiting wildtype and mutated KRAS, respectively. There was no difference in distribution of liver metastases by KRAS status (unilobar vs. bi-lobar; p = 0.58; Fisher’s Exact test) and no difference in 5-year survival according to KRAS mutation status (Log-rank test, p = 0.82) or tumour sidedness (p = 0.16). In summary, in this cohort of patients with colorectal cancer and synchronous liver metastases, neither KRAS mutation status nor tumour sidedness influenced survival.

Abstract
BACKGROUND Approximately one-fifth of patients with colorectal cancer present with hepatic metastases. There are limited prospective data on the outcomes of synchronous combined liver and bowel surgery and liver-first or bowel-first routes where contemporary chemo(radio)therapy is integrated into management. METHODS Between 1 April 2014 and 31 March 2017, 125 patients with colorectal cancer and synchronous liver metastases were recruited. Data are reported on pathway-specific outcomes, including perioperative complications, treatment completion, and overall and disease-free survival. The study was registered with ClinicalTrials.gov (NCT02456285). RESULTS There was no difference in age, body mass index, or Charlson score between surgical groups. Neoadjuvant chemotherapy was used in 50 (40%) patients for a mean duration of 4.6 months (standard deviation [SD] 5.4), and mean time from completion of chemotherapy to surgery was 2.6 months (SD 1.9). Complications were similar between patients completing the synchronous and staged pathways (p = 0.66). Mean total inpatient stay was 16.5 days (SD 8.1) for staged surgery compared with 16.8 days (SD 10.3) for the synchronous group (t-test; p = 0.91). There was no difference in time to treatment completion between pathways. Thirty six (35%) patients were disease-free at 12 months, with no significant difference between groups (Chi-square, p = 0.448). Quality of life was similar in all surgical groups. CONCLUSIONS Perioperative complications and oncological and healthcare occupancy outcomes are equivalent between patients completing staged and synchronous pathways for the management of patients with colorectal cancer and synchronous liver metastases. Future studies should focus on optimizing the criteria for pathway selection, incorporation of cancer genomics data, and patient (user) preferences.

Abstract
Background: Colorectal cancer (CRC) remains one of the leading contributors to cancer-related mortality and morbidity worldwide. Traditional Chinese medicines have been widely employed to treat various types of cancer in China. This investigation aims to determine the association between Chinese herbal medicine (CHM) therapy and survival outcomes in CRC patients with liver-limited metastases. Methods: A retrospective cohort study was performed among patients with colorectal liver metastases at the First Affiliated Hospital of Guangzhou University of Chinese Medicine in Guangzhou, China. Data from a series of consecutive patients were collected via an electronic medical record system or telephone follow-up. We defined high exposure as a period of CHM therapy lasting more than 6 months. The primary outcome was overall survival. Results: The study included the data of 191 patients from January 2008 to December 2017; 126 patients (65.97%) met the inclusion criteria of high exposure to CHM. Multivariate analyses revealed that high exposure to CHM was associated with better overall survival (hazard ratio = 0.444, 95% confidence interval = [0.213, 0.926], P = .030). The association was further confirmed by a subgroup exploratory analysis. Conclusion: Long-term CHM therapy is correlated with improved survival outcomes in CRC patients with liver-limited metastases.

Safety evaluation of simultaneous resection of colorectal primary tumor and liver metastasis after neoadjuvant therapy: A propensity score matching analysis. Am J Surg 2018; 218:894-898.

Abstract
BACKGROUND Considering the surgical safety and perioperative complications, simultaneous resection after neoadjuvant therapy is not commonly recommended. METHODS A total of 253 patients were included in study. Comparison of the short-term outcomes was performed after propensity score adjustment in Group A (n = 96) and Group B (neoadjuvant therapy, n = 96). RESULTS There was no postoperative mortality. After matching, the differences from surgical confounders were well-balanced. Morbidity (15.6% vs. 15.6%, p = 0.981), and Clavien-Dindo grade of complications (p = 0.710) were similar. No difference was found when the complications were divided according to the origin (general, colorectal and hepatic). Length of the hospital stays also did not differ between the groups (p = 0.482). More importantly, there was no increase in the number of patients with delayed adjuvant treatment after surgery in Group B. CONCLUSIONS Neoadjuvant treatment did not increase morbidity, length of hospital stays and influence adjuvant treatment after simultaneous resection.

World J Surg Oncol 2017; 15:138. [PMID: 28750680 PMCID: PMC5530936 DOI: 10.1186/s12957-017-1198-0] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2016] [Accepted: 07/03/2017] [Indexed: 02/08/2023] Open
Abstract
Background It is still under debate that whether stage IV colorectal cancer patients with unresectable metastasis can benefit from primary tumor resection, especially for asymptomatic colorectal cancer patients. Retrospective studies have shown controversial results concerning the benefit from surgery. This retrospective study aims to evaluate whether the site of primary tumor is a predictor of palliative resection in asymptomatic stage IV colorectal cancer patients. Methods One hundred ninety-four patients with unresectable metastatic colorectal cancer were selected from Sun Yat-sen University Cancer Center Database in the period between January 2007 and December 2013. All information was carefully reviewed and collected, including the treatment, age, sex, carcinoembryonic antigen, site of tumor, histology, cancer antigen 199, number of liver metastases, and largest diameter of liver metastasis. The univariate and multivariate analyses were used to detect the relationship between primary tumor resection and overall survival of unresectable stage IV colorectal cancer patients. Results One hundred twenty-five received palliative resection, and 69 received only chemotherapy. Multivariate analysis indicated that primary tumor site was one of the independent factors (RR 0.569, P = 0.007) that influenced overall survival. For left-side colon cancer patients, primary tumor resection prolonged the median overall survival time for 8 months (palliative resection vs. no palliative resection: 22 vs. 14 months, P = 0.009); however, for right-side colon cancer patients, palliative resection showed no benefit (12 vs. 10 months, P = 0.910). Conclusions This study showed that left-side colon cancer patients might benefit from the primary tumor resection in terms of overall survival. This result should be further explored in a prospective study.
