The liver is the most common site for metastasis from colorectal cancers (CRCs). There are so many new armamentarium, which have increased the life expectancy and progression-free survival. There are various available guidelines, such as NCCN, ESMO, and ASCO, which provide an insight into the latest modalities and new protocols. We have tried to elucidate into paradigm shift of the management.

Close surveillance of colorectal cancer (CRC) patients is helpful as early detection of resectable metastasis has a survival benefit. Ultrasonography (USG) is a frequently used modality to detect liver recurrence, although international guidelines do not include it. To evaluate the potential added role of USG in early detection of CRC recurrence. We performed a retrospective analysis of 230 patients of colorectal cancer treated at our institute in 2013-2014 who underwent abdominal USG for surveillance. 77/230 (33%) developed recurrence, with liver being the second most common site (22/230)...

MicroRNAs, which regulate messenger RNAs, operate through a variety of signaling pathways to participate in the development of colorectal cancer (CRC). In this study, we found that miR-143-3p expression was significantly lower in both CRC and liver metastatic CRC tissues from liver compared with normal colonic tissues. Functional assays showed that miR-143-3p inhibited CRC cell invasion and migration in vitro. Using a bioinformatics approach, we identified miR-143-3p target mRNAs. Among the candidate targets, only the expression of integrin alpha 6 (ITGA6) and ArfGAP with the SH3 domain and ankyrin repeat and PH domain 3 (ASAP3) were significantly reduced by miR-143-3p mimics as examined by western blot, and the metastasis potential of CRC cells was attenuated by endogenous ITGA6 and ASAP3 knockdown, determined by migration and invasion assays...

Colorectal cancer (CRC) is known as the third most common and fourth leading cancer associated death worldwide. The occurrence of metastasis has remained as a critical challenge in CRC, so that distant metastasis (mostly to the liver) has been manifested in about 20%-25% of patients. Several screening approaches have introduced for detecting CRC in different stages particularly in early stages. The standard treatments for CRC are surgery, chemotherapy and radiotherapy, in alone or combination. Immunotherapy is a set of novel approaches with the aim of remodeling the immune system battle with metastatic cancer cells, such as immunomodulatory monoclonal antibodies (immune checkpoint inhibitors), adoptive cell transfer (ACT) and cancer vaccine...

Liver metastasis (LM) is one of the major causes of death in patients with colorectal cancer (CRC). Approximately 60% of CRC patients develop LM during the course of their illness. About 85% of these patients have unresectable disease at the time of presentation. Surgical resection is currently the only curative treatment for patients with colorectal LM (CRLM). In recent years, with the help of modern multimodality therapy including systemic chemotherapy, radiation therapy, and surgery, the outcomes of CRLM treatment have significantly improved...

The occurrence of colorectal cancer (CRC) is associated with a variety of oncogenes and tumor‑suppressor genes. As a tumor‑suppressor gene, the liver kinase B1 gene (LKB1, also known as serine/threonine kinase 11, STK11) is closely related to tumor angiogenesis, invasion and metastasis, but its molecular mechanisms remain unclear. The aim of the present study was to investigate the effects of LKB1 on the invasion and metastasis of CRC, and to explore its molecular mechanisms. By detecting the expression of LKB1 in CRC, we can provide a reference index for diagnosing the depth of invasion and lymph node metastasis...

While colorectal and hepatic resections are commonly performed through a laparoscopic approach, the safety and feasibility of total laparoscopic synchronous resections (LSR) of colorectal liver metastasis (CRLM) have not been established. In this systematic review, short- and long-term outcomes were comparable for patients undergoing LSR and open synchronous resection. LSR was safe and feasible for patients with synchronous CRLM and should be considered in well-selected patients.
