Treatment intention and outcome in patients with simultaneously diagnosed liver and lung metastases from colorectal cancer
Menée auprès de 160 patients présentant des métastases hépatiques et pulmonaires ayant pour origine un cancer colorectal et diagnostiquées simultanément entre 2010 et 2018, cette étude analyse l'adéquation entre le traitement curatif décidé lors de la réunion de concertation pluridisciplinaire, le traitement reçu réellement et la survie
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 to 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. Simultaneous resection of liver/lung metastases and primary tumour might increase the proportion of fulfilled hepatopulmonary resections.
