Abstract
BACKGROUND Metastatic colorectal cancer (mCRC) poses a clinical challenge and requires a combination of systemic therapy and conversion surgery. Although first-line chemotherapy and targeted therapy are considered the standard treatments for mCRC, the role of primary tumor resection (PTR) in asymptomatic synchronous mCRC with unresectable metastatic lesion after initial therapy remains relatively underexplored. MATERIALS A retrospective review was conducted from January 2015 to January 2021, involving 74 patients with synchronous mCRC who received bevacizumab plus FOFIRI as first-line systemic therapy. All 74 patients had unresectable metastatic lesions confirmed through multidisciplinary team discussion. Patient characteristics, PTR data, and radiotherapy (RT) and overall survival (OS) outcomes were analyzed. The patients were categorized into a "PTR" group and a "No PTR" group and then further stratified into "4A," "4B," and "4C" subgroups based on the initial mCRC stage. Additionally, four subgroups-namely "PTR( +)/RT( +)," "PTR( +)/RT( -)," "PTR( -)/RT( +)," and "PTR( -)/RT( -)"-were formed to assess the combined effects of PTR and RT. RESULTS The median OS for all the patients was 23.8 months (20.5-27.1 months). The "PTR" group exhibited a significantly higher median OS of 25.9 months (21.3-30.5 months) compared with 21.4 months (15.8-27.1 months) in the "No PTR" group (p = 0.048). Subgroup analyses revealed a trend of improved survival with PTR in patients with stage IVA and IVB; however, the results were not statistically significant (p = 0.116 and 0.493, respectively). A subgroup analysis of PTR and RT combinations revealed no significant difference in median OS rates. CONCLUSION For asymptomatic mCRC with synchronous unresectable distant metastasis, PTR following first-line therapy with bevacizumab plus FOLFIRI may provide a potential survival benefit, particularly in stage IVA/IVB patients compared with stage IVC patients. Additionally, RT for primary tumor did not provide an additional OS benefit in mCRC with unresectable metastasis. A prospective randomized trial with a larger sample size is essential to further elucidate the role of PTR in this context.

Front Oncol 2023; 13:1138407. [PMID: 37182188 PMCID: PMC10172590 DOI: 10.3389/fonc.2023.1138407] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 04/12/2023] [Indexed: 05/16/2023] Open
Abstract
Colorectal cancer (CRC) is the second most common cause of cancer-related death among both men and women worldwide and the third most common cancer overall. About 20% of patients diagnosed with CRC were discovered to have distant metastatic lesions, the majority of which were located in the liver. For the optimum treatment of CRC patients with hepatic metastases, interventional radiologists, medical oncologists, and surgeons must all collaborate. The surgical excision of the primary tumor is an important part of CRC treatment since it has been found to be curative in cases of CRC with minimal metastases. However, given the evidence to date was gathered from retrospective data, there is still controversy over the effectiveness of primary tumor resection (PTR) in improving the median overall survival (OS) and quality of life. Patients who have hepatic metastases make up a very tiny fraction of those who are candidates for resection. With a focus on the PTR, this minireview attempted to review the current advancements in the treatment options for hepatic colorectal metastatic illness. This evaluation also included information on PTR's risks when performed on individuals with stage IV CRC.
