Treatment intention and outcome in patients with simultaneously diagnosed liver and lung metastases from colorectal cancer

Background: The aim was to assess the likelihood of patients with simultaneously diagnosed liver and lung metastases (SLLM) from colorectal cancer (CRC) to receive the curative treatment decided upon multidisciplinary team meeting (MDT) and to elaborate on the reasons for treatment intention failure and survival outcomes depending on final treatment strategy.Method: The study included a retrospective review of all patients discussed at the MDT at a single centre between 2010 and 2018 to identify all patients presenting with SLLM from CRC. Treatment intention, actual treatment outcome and reasons for treatment failure was documented. Descriptive and survival statistics were applied.Results: Of the 160 patients who had SLLM, resection of all metastatic sites was deemed possible in 107 patients (67%) of whom 39 patients (36%) finalized the curative treatment plan. The most common reason for noncompliance with management recommendations was disease progression or recurrence. Complete resection resulted in longer survival compared to patients who did not undergo resection of all metastatic sites with median survival of 63 and 27 months, respectively (p < 0.001).Conclusion: A low proportion of patients completed the initially intended curative resections. Simulta-neous resection of liver/lung metastases and primary tumour might increase the proportion of fulfilled hepatopulmonary resections.(c) 2022 The Authors. Published by Elsevier Ltd.

Automated summary

This study assessed the likelihood of colorectal cancer patients with liver and lung metastases receiving curative treatment and explored the reasons for treatment failure and survival outcomes. The results showed that only a small proportion of patients completed the initially intended curative resections, and simultaneous resection of liver/lung metastases and primary tumor may increase the proportion of fulfilled hepatopulmonary resections.
