Background: We aimed to evaluate the outcomes of resections for liver metastases (LMs) originating from pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), and esophagus/gastric cancers (EGCs), which we label as major killers (MKs; overall survival (OS) under 10%). We hypothesized that LM resection must provide the patient with almost a year of OS postoperatively that is considered beneficial.

Methods: From January 2005 to December 2020, 23 patients underwent resection for isolated LM from MKs. These patients underwent surgery after a multidisciplinary discussion about their performance status, disease evolution during prolonged medical treatment, and the existence or absence of extrahepatic metastases.

Results: LM originated from an PDAC, EGC, or NSCLC in 10 patients (43%), nine patients (39%), and four patients (18%), respectively. The median delay between primary cancer and LM diagnoses was 12 months, and the median delay between LM diagnosis and liver resection was 10 months. Most patients, who had objectively responded to medical treatment (57%), had a solitary (61%) and unilobar (70%) LM. Severe morbidity and 90-day mortality rates were 13% and 4.3%, respectively. Margin-free resection was achieved in 16 patients (70%). After liver resection, the median OS was 24 months without a statistical difference when considering the primary tumor site; 1, 3-, and 5-year OS were 70%, 23%, and 23%, respectively.

Conclusion: Selection based on criteria such as good clinical condition, response to treatment, and long observation period helped identify patients with LM of MKs who seemed to benefit from resection.
