Simple Summary: We retrospectively evaluated the clinical outcomes of lung metastasectomy in 147 patients with pulmonary metastases from primary liver tumors at three medical centers. Multivariate analysis demonstrated that surgical resection as the initial primary liver tumor treatment and lower MELD-Na scores significantly correlated with better OS. These findings can guide thoracic surgeons in patient selection and predicting surgical outcomes. Oligopulmonary metastases from primary liver tumors are typically treated surgically. We evaluated the clinical outcomes after lung metastasectomy in patients with pulmonary metastases from primary liver tumors. We retrospectively enrolled 147 consecutive patients with lung metastases from liver cancer who had undergone pulmonary metastasectomies at three medical centers between February 2007 and December 2020. All patients were pathologically confirmed to have lung metastases from liver cancer. Among the 147 patients, 110, 17, and 20 initially underwent surgical resection, radiofrequency ablation, and transcatheter arterial embolization, respectively. The 5-year overall survival (OS) in the study cohort was 22%. Univariate analysis revealed four factors associated with better OS: surgical resection as the initial primary liver tumor treatment (p = 0.004), a disease-free interval exceeding 12 months after the initial liver surgery (p = 0.036), a lower Model for End-Stage Liver Disease (MELD)-Na score (≤20) for liver cirrhosis (p = 0.044), and the absence of local liver tumor recurrence at the time of pulmonary metastasectomy (p = 0.004). Multivariate analysis demonstrated that surgical resection as the initial primary liver tumor treatment and lower MELD-Na scores significantly correlated with better OS. Our findings can assist thoracic surgeons in selecting suitable patients for surgery and predicting surgical outcomes. [ABSTRACT FROM AUTHOR]

In this article, the multidisciplinary team of the Taiwan Academy of Tumor Ablation, who have expertise in treating lung cancer, present their perspectives on percutaneous image‐guided thermal ablation (IGTA) of lung tumors. The modified Delphi technique was applied to reach a consensus on clinical practice guidelines concerning ablation procedures, including a comprehensive literature review, selection of panelists, creation of a rating form and survey, and arrangement of an in‐person meeting where panelists agreed or disagreed on various points. The conclusion was a final rating and written summary of the agreement. The multidisciplinary expert team agreed on 10 recommendations for the use of IGTA in the lungs. These recommendations include terms and definitions, line of treatment planning, modality, facility rooms, patient anesthesia settings, indications, margin determination, post‐ablation image surveillance, qualified centers, and complication ranges. In summary, IGTA is a safe and feasible approach for treating primary and metastatic lung tumors, with a relatively low complication rate. However, decisions regarding the ablation technique should consider each patient's specific tumor characteristics. [ABSTRACT FROM AUTHOR]

Simple Summary: Colorectal cancer with liver metastases (CRLM) has a poor prognosis. Systemic treatment alone, or worse, best supportive care, only affords patients limited survival. This study aims to provide evidence that aggressive local control through hepatic resection and/or radiofrequency ablation (RFA) can significantly prolong CRLM overall survival. Out of the 2612 patients enrolled in this study, 637 underwent hepatectomy, 93 had RFA, 92 were given combined hepatectomy and RFA, while 1790 received non-aggressive treatment. Based on the Kaplan–Meier curves and multivariate Cox's regression analysis as well as frequency matching analysis, we conclude that aggressive local control in CRLM patients has survival benefits, in addition to systemic therapy from a large multi-institutional database. Hepatectomy and/or local ablation therapy have been recommended for colorectal cancer liver metastases (CRLM). However, they still lack strong evidence for their survival benefits, in addition to systemic therapy. This study aims to evaluate the survival evidence of hepatectomy and/or radiofrequency ablation (RFA) therapy in CRLM patients from a large multi-institutional database. A total of 20,251 patients with colorectal cancer, 4521 of whom were with CRLM, were screened for eligibility. Finally, 2612 patients (637 hepatectomy, 93 RFA, 92 combined hepatectomy and RFA, and 1790 non-aggressive treatment) were enrolled. Frequency matching analysis was used to adjust for baseline differences. The 5-year overall survival (OS) was as follows: hepatectomy alone was 47.8%, combined hepatectomy plus RFA was 35.9%, RFA alone was 29.2%, and the non-aggressive treatment group was 7.4%. Kaplan–Meier curves showed that hepatectomy, RFA, and combination were significantly associated with a better OS compared to those without aggressive local therapy (p < 0.001). Multivariate Cox regression analysis showed that male gender (hazard ratio (HR) 0.89; 95% confidence interval (CI), 0.81–0.97; p = 0.011), old age (≥60 years) (HR 1.20; 95% CI, 1.09–1.32; p < 0.001), high CEA level (>5 ng/mL) (HR 2.14; 95% CI, 1.89–2.42; p < 0.001), primary right-sided cancer (HR 1.35; 95% CI, 1.22–1.51; p < 0.001), extrahepatic metastasis (HR 1.46; 95% CI, 1.33–1.60; p < 0.001), systemic therapy (HR 0.7; 95% CI, 0.62–0.79; p < 0.001), and aggressive local therapy (hepatectomy vs. non-local therapy HR 0.22; 95% CI, 0.20–0.26; p < 0.001; RFA vs. non-local therapy HR 0.29; 95% CI, 0.29–0.41; p < 0.001) were independent factors associated with OS. In the frequency matching analysis, patients receiving hepatectomy and/or RFA resulted in a better OS than those without (p < 0.001). In conclusion, aggressive local treatment provides survival advantages over systemic therapy alone among CRLM patients. [ABSTRACT FROM AUTHOR]

Simple Summary: Post-radiofrequency ablation (Post-RFA) fever is a common minor complication of radiofrequency ablation in patients with hepatocellular carcinoma. We aim to evaluate the risk factors and positive blood culture rate of patients with post-RFA fever. We demonstrated that when younger people with a low serum albumin level underwent general anesthesia, the tumor numbers and tumor sizes were associated with a higher rate of post-RFA fever. A low incidence of bacteremia (4.8%) among patients with post-RFA fever was a novel finding which might indicate that prophylactic antibiotics are unnecessary for patients with hepatocellular carcinoma before ablation. Post-radiofrequency ablation (RFA) fever is a self-limited complication of RFA. The correlation between post-RFA fever and bacteremia and the risk factors associated with post-RFA fever have not been evaluated. Patients with newly diagnosed or recurrent hepatocellular carcinoma who underwent ultrasonography-guided RFA between April 2014 and February 2019 were retrospectively enrolled. Post-RFA fever was defined as any episode of body temperature >38.0 °C after RFA during hospitalization. A total of 272 patients were enrolled, and there were 452 applications of RFA. The frequency of post-RFA fever was 18.4% (83/452), and 65.1% (54/83) of post-RFA fevers occurred on the first day after ablation. Patients with post-RFA fever had a longer hospital stay than those without (9.06 days vs. 5.50 days, p < 0.001). Only four (4.8%) patients with post-RFA fever had bacteremia. The independent factors associated with post-RFA fever were younger age (adjusted odds ratio (OR) = 0.96, 95% CI, 0.94–0.99, p = 0.019), low serum albumin level (adjusted OR = 0.49, 95% CI, 0.25–0.95, p = 0.036), general anesthesia (adjusted OR = 2.06, 95% CI, 1.15–3.69, p = 0.015), tumor size (adjusted OR = 1.52, 95% CI, 1.04–2.02, p = 0.032), and tumor number (adjusted OR = 1.71, 95% CI, 1.20–2.45, p = 0.003).

Objective: This study aims to explore the predictive value of demographic and clinical factors in changes in quality of life (QoL) in liver cancer (LC) patients over time. Methods: We performed a prospective cohort study in 128 patients who had 4 time point data newly diagnosed with LC at two hospitals in Taiwan. Different functional QoL was measured by QLQ‐C30. Specific characteristics were predictors for distinct functional QoL, estimated by a generalised estimating equation (GEE). Results: Patients who received liver resection or radiofrequency ablation therapy (RFA) versus transarterial chemoembolisation (TACE) or transcatheter arterial embolisation (TAE) experienced a decrease in physical function from baseline to 1 month. In addition, patients who underwent liver resection versus RFA experienced a significant recovery in cognitive functioning from baseline to 6 months. Patients with advanced stage compared to those in early stage had a reduction in physical functioning from baseline to 1 month. The alcohol intake, hepatitis C infection and the job also affected the changes in physical and cognitive functioning. Conclusion: Healthcare professionals should pay attention to changes after treatment in the short term; additionally, they need to provide health education to modifiable factors such as alcohol intake attributed to the deterioration in QoL.
