Background: Complete resection is the only potential curative treatment of synchronous colorectal liver metastases. Although simultaneous liver and colon resections became an accepted procedure at specialized centres for selected patients, there is still little data about the long-term results of simultaneous operative procedures compared with those of delayed operations. In this retrospective study, the long-term survival rates of the patients who underwent simultaneous or delayed resections were presented.
Methods: A retrospective analysis of liver resections in our institution between 1997 and 2012 was performed. Among 131 patients presented with synchronous colorectal liver metastases, 52 underwent simultaneous and 79 delayed resection. Patients with extrahepatic metastases were excluded, except for 10 patients with metastases limited to liver and lungs that were qualified as resectable.
Results: Age, sex and localization of the primary tumour were similar in the two groups. In the delayed resection group, the majority of colon resections were performed in different hospitals. The frequency of complications did not differ between the groups. The 1, 5 and 10 years survival rates were 77%, 43% and 20% in simultaneous and 86%, 37% and 19% in delayed resection group, respectively. No cancer related deaths occurred after more than 10 years of observation.
Conclusion: The long-term outcome of simultaneous resection of synchronous colorectal liver metastases is comparable to delayed resection.

Background And Objectives: Little is known about the relationship between neoadjuvant chemotherapy (NAC) and perioperative morbidity for patients undergoing combined resection of rectal cancer and sLM. The purpose of this study is to determine the impact of NAC on 30-day morbidity for patients who undergo combined resection of primary rectal cancer and sLM.
Materials And Methods: A retrospective cohort study of patients undergoing combined resection of primary rectal cancer and sLM between 2016 and 2020 at participating NSQIP hospitals.

This multicenter study explored the survival benefits of upfront primary tumor resection (PTR) followed by first-line cetuximab plus chemotherapy in real-world patients with wild-type metastatic colorectal cancer (mCRC). Treatment options for mCRC include chemotherapy, targeted therapy, immunotherapy, and surgery. The efficacy of upfront PTR in managing mCRC remains unclear.

Background: The benefit of pulmonary metastasectomy (PM) in patients with colorectal cancer (CRC) with isolated lung metastases remains unclear and failure to separate colon from rectal cancer may contribute. Utilizing a large national database, we investigate whether PM is associated with survival benefits in patients presenting with CRC with synchronous lung metastases based upon primary tumor location.
Methods: The Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015 was queried to identify patients with stage IV CRC with isolated synchronous lung metastases at initial diagnosis.

Sialic acids derived from colonic mucin glycans are crucial nutrients for enteric bacterial pathogens like . The uptake and utilization of sialic acid in depend on coordinated regulons, each activated by specific metabolites at the transcriptional level. However, the mechanisms enabling crosstalk among these regulatory circuits to synchronize gene expression remain poorly understood.

Purpose: The Japanese Grade Classification based on the status of pulmonary and mesenteric nodal metastases and the presence of extrapulmonary metastases had a prognostic value in patients with colorectal lung metastases previously. Because the survival of such patients has improved in the era of conversion therapy, this classification needs to be reaudited.
Methods: This study reviewed the treatment sequences of 126 colorectal cancer patients with synchronous lung metastases between 2010 and 2022 at our hospital.
