Dong T, Fan H, Lyu J, Shi Y, Hu P, Wu X, Sun J. A retrospective study comparing the efficacy of microwave ablation and stereotactic body radiotherapy in colorectal cancer lung metastases. Oncol Lett 2024; 28:322. [PMID: 38807676 PMCID: PMC11130612 DOI: 10.3892/ol.2024.14455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Accepted: 04/24/2024] [Indexed: 05/30/2024] Open
Abstract
The purpose of the present study was to assess and compare the efficacy of microwave ablation (MWA) and stereotactic body radiotherapy (SBRT) in the treatment of lung metastases from patients with colorectal cancer (CRC) and to identify the preferable treatment modality based on patient and tumor characteristics. Records of 118 patients with CRC with a total of 307 lung metastases who underwent SBRT or MWA between January 2015 and December 2022 were retrospectively analyzed, including the essential clinicopathological information on patients (age, sex and underlying diseases), diagnosis and treatment information [primary tumor site, levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9], imaging data [diameter of lung metastasis, location of the metastasis (i.e., whether or not the tumor was adjacent to the vessel or bronchus) and internal features] and follow-up data (postoperative therapy, complications or adverse effects and survival outcomes). For statistical analysis of the local tumor progression (LTP), disease-free survival and overall survival (OS) rates, Cox regression analysis, along with the Kaplan-Meier method adjusted using inverse probability of treatment weighting (IPTW), were performed. The median follow-up duration in the present study was 31.5 months. Multivariable Cox regression analysis revealed that the CEA level, metastasis diameter and internal features were independent predictors of OS. In the IPTW-adjusted analysis, no significant difference in the 1-year OS rate was observed between the SBRT and MWA groups (92.9 vs. 93.9%; P=0.483); however, a notable discrepancy in the treatment modalities was noted, leading to significant differences in the 2- and 3-year OS rates (65.9 vs. 57.6%, P=0.001, and 44.7 vs. 36.4%, P<0.001, respectively). A significant interaction effect for the treatment modality was observed for LTP (P=0.021). In conclusion, the present study revealed that SBRT and MWA have similar therapeutic effects in terms of prolonging the survival of patients with CRC with lung metastases; however, regarding the local control of lung metastases, MWA is associated with a number of significant advantages.

Abstract
BACKGROUND Microwave ablation (MWA) is becoming an effective therapy for inoperable pulmonary metastases from colorectal cancer (CRC). However, it is unclear whether the primary tumor location affects survival after MWA. OBJECTIVE This study aims to investigate the survival outcomes and prognostic factors of MWA based on different primary origins between colon and rectal cancer. METHODS Patients who underwent MWA for pulmonary metastases from 2014 to 2021 were reviewed. Differences in survival outcomes between colon and rectal cancer were analyzed with the Kaplan-Meier method and log-rank tests. The prognostic factors between groups were then evaluated by univariable and multivariable Cox regression analyses. RESULTS A total of 118 patients with 154 pulmonary metastases from CRC were treated in 140 MWA sessions. Rectal cancer had a higher proportion with seventy (59.32% ) than colon cancer with forty-eight (40.68% ). The average maximum diameter of pulmonary metastases from rectal cancer (1.09 cm) was greater than that of colon cancer (0.89 cm; p = 0.026). The median follow-up was 18.53 months (range 1.10 - 60.63 months). The disease-free survival (DFS) and overall survival (OS) in colon and rectal cancer groups were 25.97 vs 11.90 months (p = 0.405), and 60.63 vs 53.87 months (p = 0.149), respectively. Multivariate analyses showed that only age was an independent prognostic factor in patients with rectal cancer (HR = 3.70, 95% CI: 1.28 - 10.72, p = 0.023), while none in colon cancer. CONCLUSIONS Primary CRC location has no impact on survival for patients with pulmonary metastases after MWA, while a disparate prognostic factor exists between colon and rectal cancer.

Front Oncol 2023; 13:1174713. [PMID: 37182153 PMCID: PMC10174442 DOI: 10.3389/fonc.2023.1174713] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 04/10/2023] [Indexed: 05/16/2023] Open
Abstract
Background Thermal ablation is the primary procedure for the local treatment of lung metastases. It is known that radiotherapy and cryoablation can stimulate an abscopal effect, while the occurrence of abscopal effect induced by microwave ablation is less; the cellular and molecular mechanisms involved in the abscopal effect after microwave ablation should be further elucidated. Methods CT26 tumor-bearing Balb/c mice were treated with microwave ablation with several combinations of ablation power and time duration. The growth of primary or abscopal tumors and the survival of mice were both monitored; moreover, immune profiles in abscopal tumors, spleens, and lymph nodes were examined by flow cytometry. Results Microwave ablation suppressed tumor growth in both primary and abscopal tumors. Both local and systemic T-cell responses were induced by microwave ablation. Furthermore, the mice exhibiting significant abscopal effect after microwave ablation markedly elevated Th1 cell proportion both in the abscopal tumors and spleens. Conclusions Microwave ablation at 3 w-3 min not only suppressed tumor growth in the primary tumors but also stimulated an abscopal effect in the CT26-bearing mice via the improvement of systemic and intratumoral antitumor immunity.

Abstract
Colorectal cancer is one of the leading causes of cancer-associated morbidity and mortality in the world, with lower survival rates when metastases are present. We present a case of a 69-year-old man, diagnosed with metastatic rectal cancer to the lungs in 2015. Over the course of 5 years, he was treated with 4 microwave ablation procedures to both his lungs. Despite this, he does not have any local recurrence or any symptoms since he was first diagnosed 7 years ago. This case highlights the potential for microwave ablation to be used for curative intent in pulmonary metastases in colorectal cancer as an alternative to more invasive and complex procedures such as metastasectomies or lung resection, as well as the benefit of using microwave ablation for disease control to improve patients’ quality of life.

The Role of Conventional and Stereotactic Microwave Ablation for Intrahepatic Cholangiocarcinoma. J Clin Med 2021; 10:jcm10132963. [PMID: 34279447 PMCID: PMC8268028 DOI: 10.3390/jcm10132963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 06/02/2021] [Accepted: 06/30/2021] [Indexed: 11/17/2022] Open
Abstract
Background: The incidence and mortality of intrahepatic cholangiocarcinoma (ICCA) is increasing worldwide and curative treatment options are limited due to the aggressive tumor biology and often late diagnosis. Resection of the primary tumor remains the only curative therapy available, as the benefit of palliative chemotherapy and radiotherapy is relatively small. In contrast to hepatocellular carcinoma, minimal-invasive thermal tumor ablation, and in particular stereotactic tumor ablation for small primary cancers or metastases, is not established and data are scarce. Methods: We conducted a literature review in the field of ICCA ablation and retrospective analysis of 10 patients treated by stereotactic microwave ablation (SMWA) for either primary ICCA or liver metastases of ICCA. Results: While current guidelines have no consensus for ablation of primary ICCA, some state that it might be an option in inoperable patients or those with recurrent disease. The literature review revealed 11 studies on microwave ablation for ICCA reporting that MWA for ICCA ≤ 5 cm might be safe and could be a treatment option for patients who are not candidates for surgery. No data has been published on stereotactic microwave ablation (SMWA) for ICCA. The analyses of our own data of 10 patients treated by SMWA for primary ICCA (n = 5) or recurrent ICCA (n = 5) show that the treatment is safe and efficient with short hospital stays and low complication rates. Conclusion: Although thermal ablation, and in particular SMWA, might be a minimally invasive and tissue-sparing curative treatment alternative for small ICCA in the diseased liver and ICCA metastases, the oncologic benefit still needs to be shown in larger studies with longer follow-up.

Assessment of the Outcomes of Intrahepatic Cholangiocarcinoma After Ultrasound-Guided Percutaneous Microwave Ablation Based on Albumin-Bilirubin Grade. Cardiovasc Intervent Radiol 2020; 44:261-270. [PMID: 33057809 DOI: 10.1007/s00270-020-02637-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Accepted: 08/27/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To determine whether albumin-bilirubin (ALBI) grade could be used to predict the outcomes of patients with intrahepatic cholangiocarcinoma (ICC) who underwent ultrasound-guided percutaneous microwave ablation (MWA). MATERIALS AND METHODS This retrospective study was approved by the institutional review board, and the requirement for informed consent was waived. We studied 52 treatment-naïve patients with 74 ICC lesions according to the Milan criteria who subsequently underwent MWA from April 2011 to March 2018. Overall survival (OS) and recurrence-free survival (RFS) were compared in groups classified by Child-Pugh score and ALBI grade, which were statistically analyzed with the log-rank test. Cox proportional hazard regression analyses were used to determine the prognostic factors for survival in patients with ICC. RESULTS The median follow-up time was 21.2 months (3.2-78.7 months). Seventeen patients died during this period. After MWA, the cumulative 1-, 3-, and 5-year OS rates were 87.4%, 51.4%, and 35.2%, respectively, and the cumulative 1-, 3-, and 5-year RFS rates were 68.9%, 56.9%, and 56.9%, respectively. The major complication rate was 3.8% (2/52). Stratified according to ALBI grade, the cumulative 1-, 3-, and 5-year OS rates were 95.5%, 72.4%, and 72.4% for patients with ALBI grade 1 and 62.5%, 40.6%, and 36.3% for patients with ALBI grade 2, respectively, showing a significant difference (P = 0.006). Multivariate analysis results showed that older age (hazard ratio [HR]: 1.67, 95% confidence interval [CI]: 1.11-2.82; P = 0.002), tumor size ≥ 3 cm in diameter (HR: 11.33, CI: 2.24-34.52; P = 0.021) and ALBI grade (HR: 8.23, CI: 1.58-58.00; P = 0.004) may be predictors of poor OS. CONCLUSION ALBI grade was validated as a significant biomarker for predicting survival in ICC patients within the Milan criteria who underwent MWA.

Abstract
OBJECTIVES To prospectively assess reproducibility, safety, and efficacy of microwave ablation (MWA) in the treatment of unresectable primary and secondary pulmonary tumors. METHODS Patients with unresectable primary and metastatic lung tumors up to 4 cm were enrolled in a multicenter prospective clinical trial and underwent CT-guided MWA. Treatments were delivered using pre-defined MW power and duration settings, based on target tumor size and histology classifications. Patients were followed for up to 24 months. Treatment safety, efficacy, and reproducibility were assessed. Ablation volumes were measured at CT scan and compared with ablation volumes obtained on ex vivo bovine liver using equal treatment settings. RESULTS From September 2015 to September 2017, 69 MWAs were performed in 54 patients, achieving technical success in all cases and treatment completion without deviations from the standardized protocol in 61 procedures (88.4%). Immediate post-MWA CT scans showed ablation dimensions smaller by about 25% than in the ex vivo model; however, a remarkable volumetric increase (40%) of the treated area was observed at 1 month post-ablation. No treatment-related deaths nor complications were recorded. Treatments of equal power and duration yielded fairly reproducible ablation dimensions at 48-h post-MWA scans. In comparison with the ex vivo liver model, in vivo ablation sizes were systematically smaller, by about 25%. Overall LPR was 24.7%, with an average TLP of 8.1 months. OS rates at 12 and 24 months were 98.0% and 71.3%, respectively. CONCLUSIONS Percutaneous CT-guided MWA is a reproducible, safe, and effective treatment for malignant lung tumors up to 4 cm in size. KEY POINTS • Percutaneous MWA treatment of primary and secondary lung tumors is a repeatable, safe, and effective therapeutic option. • It provides a fairly reproducible performance on both the long and short axis of the ablation zone. • When using pre-defined treatment duration and power settings according to tumor histology and size, LPR does not increase with increasing tumor size (up to 4 cm) for both primary and metastatic tumors.

Abstract
PURPOSE To assess the efficacy of the albumin-bilirubin (ALBI) grade on assessing long-term outcomes of computed tomography (CT)-guided percutaneous microwave ablation (CT-PMWA) in the treatment of patients with intrahepatic cholangiocarcinoma (ICC). METHODS Between April 2011 and March 2018, 78 patients who underwent CT-PMWA were enrolled in this study. Overall survival (OS) and recurrence-free survival (RFS) were compared in the groups stratified by the ALBI grade and Child-Pugh score. Cox proportional hazard regression analyses were performed to determine independent predictors of OS and RFS. RESULTS After a median follow-up of 22.7 months (range 1-86.7 months), 67 patients had died. The cumulative 1-, 3-, and 5-year OS rates were 89.5%, 52.2%, and 35.0%, respectively. Stratified by the ALBI grade, the cumulative 1-, 3-, and 5-year OS rates were 100%, 69.2%, and 25.6% for patients with the grade 1, respectively. For patients with the ALBI grade 2, the cumulative 1-, 3-, and 5-year OS rates were 41.0%, 10.3%, and 10.3%, respectively. Patients with a hepatic function of the ALBI grade 1 had significantly higher OS rates than patients with the ALBI grade 2 (p < .001). The multivariate analysis showed tumor size (Hazard Ratio[HR] 95% Confidence Interval[CI]:9.03[1.01-80.52], p = .049) and the ALBI grade (HR[95%CI]:9.56[1.58-58.00], p = .014) were associated with OS, and tumor size (HR: 2.03[0.69-8.04], p = .049) was associated with RFS. CONCLUSIONS The preliminary data of this study showed the ALBI grade was effective to predict long-term outcomes of CT-PMWA in ICCs. Further study is necessary to validate our results by a large, multi-center patient cohort.

Abstract
PURPOSE Microwave ablation (MWA) is a recently developed thermal ablation technique that has been used for the treatment of different types of tumours. In the present study, we retrospectively evaluated the safety and efficacy of CT-guided percutaneous MWA for the treatment of colorectal cancer (CRC) pulmonary metastases. MATERIALS AND METHODS From June 2010 to June 2015, 48 unresectable lesions in 32 patients with CRC pulmonary metastases were subjected to CT-guided MWA. Imaging follow-up was with contrast-enhanced CT and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT. RESULTS Oncologic imaging showed that 42 (87.5%) of the 48 lesions in the 32 patients were completely ablated. Needle track metastatic seeding was not found, and no patient deaths occurred within 30 d after ablation. The mean hospital stay was 3 d (range, 2-7 d). Pneumothorax was the most frequent complication and occurred in 6 (12.5%) of the 48 lesions. The median survival time was 31 months (95% CI: 15.4-46.6). The 1-, 2- and 3-year survival rates were 79.5%, 63.1% and 44.4%, respectively. Univariate Cox regression analysis showed that tumour size, disease-free interval (DFI) and number of tumours were significantly related to the overall survival time (p = .007, p = .022 and p = .030, respectively). Multivariate analysis showed that tumour size was an independent prognostic factor for survival (p = .017). CONCLUSION CT-guided percutaneous MWA is a safe and effective minimally invasive method for treating CRC pulmonary metastases.
