Brief Summary

Colorectal cancer (CRC) and chronic limb-threatening ischemia (CLTI) are relatively frequent and potentially fatal diseases. However, studies that are comparing clinical outcomes between CRC and CLTI patients in more advanced stages of the disease are lacking. The study aim was to evaluate outcomes of patients with colorectal cancer liver metastases (CRLM) treated by curative-intent liver resection and CLTI patients according to wound, ischemia, foot infection (WIfI) classification by comparing the short- and long-term clinical outcomes.

Detailed Description

Peripheral arterial disease (PAD) is characterized by a global pandemic of growing proportions. In 2016, The Global Burden of Disease study reported that 202 million adults worldwide have PAD, with a higher prevalence compared to ischaemic heart disease (154 million), Alzheimer's disease (64 million) and cancer (43 million). The patient prognosis after PAD occurrence is poor because the disease often progresses to chronic limb-threatening ischemia (CLTI) that is an end-stage disease.

The 5-year mortality risk in CLTI patients is about 60%. When the mortality risk of CLTI is compared to mortality rates of the most common malignant diseases only six of them have a higher 5-year mortality rate compared to CLTI. One of them is colorectal cancer (CRC). CRC is the third most commonly occurring cancer in men and the second most commonly occurring cancer in women.

According to the latest CLTI treatment guidelines, the Society for Vascular Surgery (SVS) WIfI (wound, infection, ischemia) classification should be employed to stage limb condition in patients with CLTI that is analog to the use of tumor, nodes, metastases (TNM) cancer staging system. Recent data indicate that WIfI appears to correlate strongly with important clinical outcomes.

The annual incidence of CLTI is greater than the incidence of cancers characterized by high mortality rates (esophageal, stomach, brain and ovarian). In addition, more people die from CLTI each year compared to death rates of the already mentioned cancers. However, studies that are comparing clinical outcomes between cancer and CLTI patients in more advanced stages of the disease are lacking.

The study aim was to evaluate outcomes of the wound, ischemia, foot infection (WIfI) stage IV CLTI and colorectal cancer liver metastases (CRLM) patients managed by curative-intent liver resection by comparing the short- and long-term clinical outcomes.
