Background:
Owing to the heterogeneity of underlying primary tumors, noncolorectal, nonneuroendocrine metastases to the liver (NCNNMLs), although relatively rare, pose major challenges to treatment and long-term management. Despite being considered the gold standard for colorectal cancer liver metastases, the role of surgical resection for NCNNML remains controversial. Furthermore, advancements in locoregional treatment modalities, such as ablation and various chemotherapeutic modalities, have contributed to the treatment of patients with NCNNML.
Methods:
This was a comprehensive review of literature that used Medline/PubMed, Google Scholar, the Cochrane Library, and the Web of Science, which were accessed between 2014 and 2024.
Results:
NCNNMLs are rare tumor entities with varied presentation and outcomes. A multidisciplinary approach, which includes chemotherapy, surgery, and interventional radiologic techniques, can be implemented with good results.
Conclusion:
Given the complex nature of NCNNML, its management should be highly individualized and multidisciplinary. Locoregional treatments, such as surgical resection and/or ablation, may be more appropriate for select patients and should be offered as a viable therapeutic option for a subset of individuals.
Insights
Noncolorectal, nonneuroendocrine liver metastases (NCNNMLs) present unique challenges. A multidisciplinary approach combining chemotherapy, surgery, and interventional radiology offers good outcomes for these rare tumors.
Area of Science:
- Hepatobiliary Medicine
- Surgical Oncology
- Interventional Radiology
Background:
- Noncolorectal, nonneuroendocrine liver metastases (NCNNMLs) are rare and complex due to primary tumor heterogeneity.
- Surgical resection, a standard for colorectal metastases, has a controversial role in NCNNML management.
- Locoregional therapies like ablation and chemotherapy are evolving treatment options for NCNNMLs.
Purpose of the Study:
- To review the current literature on the management of noncolorectal, nonneuroendocrine liver metastases.
- To evaluate the efficacy of various treatment modalities for NCNNMLs.
- To discuss the role of a multidisciplinary approach in optimizing patient outcomes.
Main Methods:
- Comprehensive literature review utilizing Medline/PubMed, Google Scholar, Cochrane Library, and Web of Science.
- Searched databases for studies published between 2014 and 2024.
- Synthesized findings on NCNNML presentation, treatment, and outcomes.
Main Results:
- NCNNMLs are rare entities with diverse clinical presentations and prognoses.
- A multidisciplinary strategy integrating chemotherapy, surgery, and interventional radiology demonstrates positive results.
- Locoregional treatments are effective for select NCNNML cases.
Conclusions:
- Individualized, multidisciplinary management is crucial for complex NCNNML cases.
- Surgical resection and/or ablation are viable therapeutic options for carefully selected NCNNML patients.
- A tailored approach enhances treatment efficacy for noncolorectal, nonneuroendocrine liver metastases.
