Abstract
PURPOSE To retrospectively evaluate safety and effectiveness of CT-guided percutaneous microwave ablation (MWA) in 47 patients with medically inoperable stage I peripheral non-small cell lung cancer (NSCLC). METHODS From February 2008 to October 2012, 47 patients with stage I medically inoperable NSCLC were treated in 47 MWA sessions. The clinical outcomes were evaluated. Complications after MWA were also summarized. RESULTS At a median follow-up period of 30 months, the median time to the first recurrence was 45.5 months. The local control rates at 1, 3, 5 years after MWA were 96%, 64%, and 48%, respectively. The median cancer-specific and median overall survivals were 47.4 and 33.8 months. The overall survival rates at 1, 2, 3, and 5 years after MWA were 89%, 63%, 43%, and 16%, respectively. Tumors ≤3.5 cm were associated with better survival than were tumors >3.5 cm. The complications after MWA included pneumothorax (63.8%), hemoptysis (31.9%), pleural effusion (34%), pulmonary infection (14.9%), and bronchopleural fistula (2.1%). CONCLUSIONS MWA is safe and effective for the treatment of medically inoperable stage I peripheral NSCLC.

Abstract
Although surgical resection with curative intent is the main therapy for both primary and metastatic lung tumors, about 80% of lung cancers cannot be removed by surgery. Because most patients with unresectable lung cancer only receive limited benefits from traditional radiotherapy and chemotherapy, many novel local treatment modalities have emerged including local ablation therapy. The Minimally Invasive Treatment of Lung Cancer Branch, Professional Committee of Minimally Invasive Treatment of Cancer of the Chinese Anti-Cancer Association and Committee on Tumor Ablations, Chinese College of Interventionalists have organized multidisciplinary experts to develop guidelines for this treatment modality. These guidelines aim at standardizing thermal ablation procedures, describing the indications for candidates, assessing outcomes, and preventing postablation complications.

Abstract
As a treatment option for cancer, thermal ablation has satisfactory effects on many types of solid tumors (such as liver and renal cancers). However, its clinical applications for the treatment of thyroid nodules and metastatic cervical lymph nodes are still under debate both in China and abroad. In 2015, the "Zhejiang Expert consensus on thermal ablation for thyroid benign nodules, microcarcinoma, and metastatic cervical lymph nodes (2015 edition)," was released by the Thyroid Cancer Committee of Zhejiang Anti-Cancer Association, China. To further standardize the application of thermal ablation for thyroid tumors, the Thyroid Tumor Ablation Experts Group of Chinese Medical Doctor Association has organized many seminars and finally produced a consensus to formulate the "Expert consensus workshop report: Guidelines for thermal ablation of thyroid tumors (2019 edition)."

Abstract
Purpose The purpose of the study is to retrospectively evaluate the safety and efficacy of microwave ablation (MWA) for the treatment of ground-glass opacity (GGO)-lung adenocarcinoma. Materials and Methods From December 2013 to June 2017, a total of 51 patients (22 males and 29 females, mean age of 69.4 ± 10.1 years) were included in this study, with 51 lung adenocarcinoma lesions showing GGO (mean long-axis diameter of 18.7 ± 6.05 mm). They received a total of 52 sessions of percutaneous computed tomography-guided (CT-guided) MWA. First, lung adenocarcinoma with GGO was histologically defined by needle biopsy under the guidance of CT. Second, the efficacy of CT-guided MWA was analyzed, including the feasibility, safety, 3 years local progression-free survival (LPFS), 3 years disease-specific survival, and 3 years overall survival (OS). Final, complications after MWA were also summarized. Results The technical success rate was 100%, without MWA procedure-related death. At the median follow-up period (27.02, range: 7-45 months), the rates of 3 years LPFS, cancer-specific survival, and OS were 98%, 100%, and 96%, respectively. The complications after MWA included pneumothorax (48.1%, 25/52), hemoptysis (28.8%, 14/52), pleural effusion (23.1%, 12/52), and pulmonary infection (7.7%, 4/52). Conclusions CT-guided percutaneous MWA was a feasible, safe, and effective therapeutic approach for treating GGO-lung adenocarcinoma.

Abstract
Purpose: The present study retrospectively evaluated the feasibility, safety, and short-term efficacy of computed tomography (CT)-guided percutaneous microwave ablation (MWA) to treat multiple synchronous ground-glass opacities (GGOs) of the lung.Materials and Methods: From October 2016 to May 2019, 33 patients (9 males and 24 females, mean age: 59.6 ± 10.0 years) with multiple GGOs (103 GGOs with mean size 12.3 ± 6.3 mm) were enrolled in this study. Patients underwent 66 procedures of CT-guided percutaneous MWA. The feasibility, safety, local progression-free survival, and overall survival were evaluated.Results: The technical success and technique efficacy rate were 100% and no MWA procedure-related deaths were reported. The median follow-up period was 18.1 (range: 6.8-37.7) months. Major complications included pneumothorax (11/66, 16.7%), pleural effusion (2/66, 3.0%), pneumonia (3/66, 4.5%), and nerve injury (1/66, 1.5%), which were well controlled by appropriate treatment. Minor complications included pneumothorax (38/66, 57.6%), pleural effusion (43/66, 65.2%), hemoptysis (13/66, 19.7%), subcutaneous emphysema (4/66, 6.1%), and hemothorax (2/66, 3.0%). Currently, all patients are alive without local progression or tumor recurrence, despite the relatively insufficient follow-up time.Conclusion: CT-guided percutaneous MWA for the treatment of multiple synchronous lung GGOs is feasible, safe, and efficacious over short-term follow-up. It may also be employed as an alternative approach for nonsurgical candidates. A longer follow-up is warranted to evaluate the oncologic outcomes.

Microwave ablation as local consolidative therapy for patients with extracranial oligometastatic EGFR-mutant non-small cell lung cancer without progression after first-line EGFR-TKIs treatment. J Cancer Res Clin Oncol 2020; 146:197-203. [PMID: 31599340 DOI: 10.1007/s00432-019-03043-6] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2019] [Accepted: 09/30/2019] [Indexed: 12/18/2022] [Imported: 10/16/2023]
Abstract
OBJECTIVES Evidence from multiple clinical trials showed that local consolidative therapy (LCT) improved survival in oligometastatic non-small cell lung cancer (NSCLC) patients. In the present study, we aim to explore the potential role of microwave ablation (MWA) as LCT for epidermal growth factor receptor (EGFR)-mutant advanced NSCLC patients with extracranial oligometastasis. MATERIALS AND METHODS From January 2015 to December 2018, a total of 86 EGFR-mutant stage IIIB or IV NSCLC patients with extracranial oligometastasis were enrolled for retrospective analysis. MWA was used as LCT for all oligometastatic lesions and/or primary tumors in 34 patients without progression after first-line EGFR-TKIs therapy (consolidation group), while the other 52 patients received only TKIs until disease progression (monotherapy group). We calculated and compared the progression-free survival (PFS) and overall survival (OS) of the two groups. RESULTS AND CONCLUSION Patients with MWA consolidation therapy had significantly improved PFS (median 16.7 vs. 12.9 months, HR 0.44, 95% CI 0.22-0.88, P = 0.02) and OS (median: 34.8 vs. 22.7 months, HR 0.45, 95% CI 0.24-0.88, P = 0.04) than monotherapy group. MWA for LCT was identified as the independent predictive factor for better PFS (HR 0.46, 95% CI 0.37-0.82, P < 0.01) and OS (HR 0.57, 95% CI 0.33-0.91, P = 0.02). Most toxicities were mild and well tolerated. No patient had to discontinue EGFR-TKIs because of MWA complications. These findings suggest that MWA as local consolidative therapy after first-line EGFR-TKIs treatment leads to better disease control and survival than TKIs monotherapy in EGFR-mutant advanced NSCLC patients with extracranial oligometastasis. MWA as a novel option of LCT might be considered for clinical management of these patients.

Abstract
BACKGROUND The safety and effectiveness of repeated computed tomography-guided percutaneous microwave ablation (MWA) in the management of local recurrence (LR) in patients with medically inoperable Stage I nonsmall cell lung cancer (NSCLC) were retrospectively evaluated. MATERIALS AND METHODS From February 2008 to August 2014, 104 patients with medically inoperable Stage I NSCLC received MWA. Patients with LR were given repeat MWA. The clinical outcomes and complications of repeat MWA for LR were evaluated. RESULTS At a median follow-up of 47 months, LR occurred in 24/104 (23.1%) patients within 12 ± 8 months after MWA. LR rates were higher in tumors> 3.5 cm than that of tumors ≤3.5 cm (35.7% vs. 18.4%). Local control of the repeat MWA was achieved in 21 of 24 (87.5%) patients. Overall survival (OS) and progress-free survival (PFS) for patients without LR were similar to that of with LR and receiving repeat MWA (OS: 48 m vs. 41.5 m; PFS: 42 m vs. 32 m). The OS rates were 100%, 74.6%, 60.6%, and 27% for patients without LR at 1, 2, 3, and 5 years, and they were 96.4%, 69.5%, 60.6%, and 26.1% for patients with repeat MWA for LR. Repeat MWA for LR was not associated with more significant complications. CONCLUSION The LR was higher in tumors> 3.5 cm than that of in tumors ≤3.5 cm. For patients with LR, it was feasible and effective to use MWA repeatedly to achieve the similar OS and PFS as patients without LR. No additional complications were reported in the repeat MWA compared to the original MWA.

Abstract
PURPOSE To retrospectively evaluate local efficacy and survival after microwave (MW) ablation of lung tumors and identify predictors of prognosis. MATERIALS AND METHODS Data from 183 consecutive patients (67 women; mean age, 61.5 y ± 13.4) with lung tumors who had undergone 203 lung MW ablation sessions from January 2011 to May 2013 were assessed. The χ2 test, independent-samples t test, Kaplan-Meier analysis, and Cox regression model analysis were used to estimate survival rates and evaluate significance of factors affecting rates of incomplete ablation, local progression, remote progression-free survival (RPFS), and cancer-specific survival (CSS). RESULTS Technical success rate was 100%. Incomplete ablation rate after 183 first MW ablations was 14.2% (26 of 183); maximum diameter of target tumors (P = .00001) was associated with incomplete ablation on univariate analysis. The local progression rate was 19.1% (35 of 183); emphysema (P = .020) and maximum diameter of target tumor (P = .000003) were associated with local progression. Median and 4-year RPFS were 15.0 months (95% confidence interval [CI], 11.1-18.9 mo) and 23.8%, respectively. Tumor stage (P < .01) and incomplete ablation (P = .002) were independent predictors of RPFS. Median and 4-year CSS were 24.9 months (95% CI, 19.9-29.9 mo) and 31.1%, respectively. Median and 4-year overall survival were 23.7 months (95% CI, 20.6-26.8 mo) and 29.6%, respectively. Tumor stage (P < .01) and maximum diameter (P = .009) were independent risk factors for CSS. CONCLUSIONS MW ablation is effective for lung tumors, especially small lesions of early-stage primary lung cancer and solitary lung metastasis.

Abstract
OBJECTIVES This prospective trial was performed to verify whether microwave ablation (MWA) in combination with chemotherapy could provide superior survival benefit compared with chemotherapy alone. MATERIALS AND METHODS From March 1, 2015, to June 20, 2017, treatment-naïve patients with pathologically verified advanced or recurrent non-small cell lung cancer (NSCLC) were randomly assigned to MWA plus chemotherapy group or chemotherapy group. The primary endpoint was progression-free survival (PFS), while the secondary endpoints included overall survival (OS), time to local progression (TTLP), and objective response rate (ORR). The complications and adverse events were also reported. RESULTS A total of 293 patients were randomly assigned into the two groups. One hundred forty-eight patients with 117 stage IV tumors were included in the MWA plus chemotherapy group. One hundred forty-five patients with 113 stage IV tumors were included in the chemotherapy group. The median follow-up period was 13.1 months and 12.4 months, respectively. Median PFS was 10.3 months (95% CI 8.0-13.0) in the MWA plus chemotherapy group and 4.9 months (95% CI 4.2-5.7) in the chemotherapy group (HR = 0.44, 95% CI 0.28-0.53; p < 0.0001). Median OS was not reached in the MWA plus chemotherapy group and 12.6 months (95% CI 10.6-14.6) in the chemotherapy group (HR = 0.38, 95% CI 0.27-0.53; p < 0.0001) using Kaplan-Meier analyses with log-rank test. The median TTLP was 24.5 months, and the ORR was 32% in both groups. The adverse event rate was not significantly different in the two groups. CONCLUSIONS In patients with advanced NSCLC, longer PFS and OS can be achieved with the treatment of combined MWA and chemotherapy than chemotherapy alone. KEY POINTS • Patients treated with MWA plus chemotherapy had superior PFS and OS over those treated with chemotherapy alone. • The ORR of patients treated with MWA plus chemotherapy was similar to that of those treated with chemotherapy alone. • Complications associated with MWA were common but tolerable and manageable.

Abstract
Although surgical lobectomy with systematic mediastinal lymph node evaluation is considered as the "gold standard" for management of early stage non-small cell lung cancer (NSCLC), image-guided percutaneous thermal ablation has been increasingly used for medically inoperable patients. Radiofrequency ablation (RFA) is a research-based technique that has the most studies for medically inoperable early-stage NSCLC. Other thermal ablation techniques used to treat pulmonary tumors include microwave ablation (MWA), cryoablation and laser ablation. MWA has several advantages over RFA including reduced procedural time, reduced heat-sink effect, large ablation zones, decreased susceptibility to tissue impedance, and simultaneous use of multiple antennae. This review article highlights the most relevant updates of MWA for the treatment of early-stage NSCLC, including mechanism of action, clinical outcomes, potential complications, the existing technique problems and future directions.

Abstract
OBJECTIVES In the present study, we aim to show the results of microwave ablation (MWA) for medically inoperable stage I non-small cell lung cancers (NSCLCs) with long-term follow-up. METHODS From Feb 2011 to Mar 2016, patients with histologically proven clinical stage I NSCLC were treated with CT-guided MWA and retrospectively analyzed. The primary end point was overall survival (OS). Secondary end points included disease-free survival (DFS), cancer-specific survival (CSS), and complications. RESULTS A total of 105 patients with 105 lesions underwent MWA. The mean age was 70.7 years (range: 40-86 years), and the mean diameter of all lesions was 2.40 cm (range: 0.9-4.0 cm). Adenocarcinoma was the most common histological type (77, 73.3%), followed by squamous cell carcinomas (21, 20%) and undefined NSCLC (7, 6.7%). With a median follow-up of 54.8 months, the median DFS was 36.0 months, and 1-, 3-, and 5-year DFS rates were 89.5%, 49.4%, and 42.7%, respectively. The median CSS and OS were 89.8 and 64.2 months, respectively. The OS rate was 99% at 1 year, 75.6% at 3 years, and 54.1% at 5 years, while the CSS rates were 99%, 78.9%, and 60.9%, respectively. Patients with stage IB lesions had significant shorter DFS (22.3 months vs. undefined, HR: 11.5, 95%CI: 5.85-22.40) and OS (37.3 vs. 89.8 months, HR: 8.64, 95% CI: 4.49-16.60) than IA disease. CONCLUSION MWA is a safe, effective, and potentially curative therapy for medically inoperable stage I NSCLC patients. KEY POINTS • In this multicenter retrospective study which included 105 patients, we found the median overall survival (OS) was 64.2 months. The OS rate was 99% at 1 year, 75.6% at 3 years, and 54.1% at 5 years. • Procedures were technically successful and well tolerated in all patients. Most MWA complications were mild or moderate.

Abstract
OBJECTIVE To retrospectively evaluate the efficacy and safety of microwave ablation (MWA) combined with osteoplasty in lung cancer patients with painful extraspinal bone metastases. MATERIALS AND METHODS From January 2011 to July 2014, 26 lung cancer patients with 33 painful extraspinal bone metastases underwent percutaneous MWA combined with osteoplasty. Effectiveness was evaluated by visual analog scale (VAS) and daily morphine dose with a follow-up of 6-months. Complications were also recorded. RESULTS Mean VAS score and morphine dose pre-procedure were 7.4 ± 1.6 (range, 5-10) and 47.7 ± 30.1 mg (range, 20-120 mg), respectively. Technical success and pain relief were achieved in all patients. Mean VAS scores and daily morphine doses post-procedure were as follows: 48 h, 1.7 ± 1.2 (p < 0.001) and 29.6 ± 16.1 mg (p = 0.003); 7 days, 1.9 ± 1.7 (p < 0.001) and 16.1 ± 12.0 mg (p < 0.001); 1 month, 1.5 ± 0.9 (p < 0.001) and 10.8 ± 10.9 (p < 0.001); 3 months, 0.9 ± 0.7 (p < 0.001) and 8.4 ± 9.2 mg (p < 0.001); and 6 months, 1.2 ± 0.8 (p < 0.001) and 9.2 ± 12.3 mg (p < 0.001). Complications were observed in eight patients (28%); among these, major complications were reported in two (7.7%) patients, one with local infection and the other with a bone fracture. The minor complication rate was 23.1% (6/26). CONCLUSION MWA combination with osteoplasty appeared to be an effective and safe treatment for lung cancer patients with painful extraspinal bone metastases.

Abstract
Despite the application of antiviral drugs and improved surveillance tools, the number of patients diagnosed with hepatocellular carcinoma (HCC) at an advanced stage and with a dismal prognosis is still on the rise. Systemic treatment with multiple multitargeted tyrosine kinase inhibitors (TKIs), such as sorafenib, has been a widely utilized approach for a decade. In addition, the use of a combination of TKIs with other types of compounds, including immune checkpoint inhibitors (ICIs) and antiangiogenic inhibitors, has shown efficacy in treating advanced HCC. However, the presence of intolerable adverse events, low disease response and control rates, and relative short overall survival of such combinatory therapies makes novel or optimized therapies for advance HCC urgently needed. Locoregional therapy (transarterial chemoembolization, and thermal ablation) can destroy primary tumors and decrease tumor burden and is widely used for HCC management. This type of treatment modality can result in local hypoxia and increased vascular permeability, inducing immunogenic effects by releasing tumor antigens from dying cancer cells and producing damage-associated molecular patterns that facilitate antiangiogenic therapy and antitumor immunity. The combination of systemic and locoregional therapies may further produce synergistic effects without overlapping toxicity that can improve prognoses for advanced HCC. In preliminary studies, several combinations of therapeutic modes exhibited promising levels of safety, feasibility, and antitumor effects in a clinical setting and have, thus, garnered much attention. This review aims to provide a comprehensive, up-to-date overview of the underlying mechanisms of combined systemic and locoregional therapies in the treatment of advanced HCC, commenting on both their current status and future direction.

Abstract
The non-small cell lung cancer (NSCLC) patients that experienced good clinical response to epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKIs) will ultimately develop acquired resistance. This retrospective study was performed to explore the potential survival benefit of microwave ablation (MWA) therapy in epidermal growth factor receptor (EGFR)-mutant NSCLC that developed extra-central nervous system (CNS) oligoprogressive disease during TKI treatment.We retrospectively analyzed 54 NSCLC patients with EGFR mutations who showed a clinical benefit from initial EGFR-TKI therapy and developed extra-CNS oligoprogressive disease at our institutions. Twenty eight patients received MWA as a local therapy for the metastatic sites and continued on the same TKIs (MWA group). The following 26 patients received systemic chemotherapy after progression (chemotherapy group). The progression-free survival (PFS1) was calculated from initiation of targeted therapy to first progression. Progression-free survival (PFS2) was defined from first progression to second progression after MWA or chemotherapy. Overall survival (OS) was calculated from the time of diagnosis to the date of last follow-up or death.The median PFS1 for both groups was similar (median 12.6 vs. 12.9 months, HR 0.63). However, the MWA group patients had a significantly longer PFS2 (median 8.8 vs. 5.8 months, hazards ratio [HR] 0.357) and better OS (median 27.7 vs. 20.0, HR 0.238) in comparison with chemotherapy group. Multivariate analysis and the internal validation identified MWA as the main favorable prognostic factor for PFS2 and OS. In the MWA group, the median PFS2 for complete ablation was significantly longer than that for incomplete ablation (11 vs. 4.2 months, HR 0.29, P < 0.05).MWA with continued EGFR inhibition might be associated with favorable progression-free survival (PFS) and OS in patients with extra-CNS oligometastatic disease. MWA as a local therapy for extra-CNS oligometastatic disease should be considered for NSCLC with acquired resistance to EGFR-TKIs.

Abstract
Although surgical resection is the primary means of curing both primary and metastatic lung cancers, about 80% of lung cancers cannot be removed by surgery. As most patients with unresectable lung cancer receive only limited benefits from traditional radiotherapy and chemotherapy, many new local treatment methods have emerged, including local ablation therapy. The Minimally Invasive and Comprehensive Treatment of Lung Cancer Branch, Professional Committee of Minimally Invasive Treatment of Cancer of the Chinese Anti-Cancer Association has organized multidisciplinary experts to develop guidelines for this treatment modality. These guidelines aim at standardizing thermal ablation procedures and criteria for selecting treatment candidates and assessing outcomes; and for preventing and managing post-ablation complications.

Abstract
Background Previous studies have documented the therapeutic value of computed tomography (CT)‐guided percutaneous microwave ablation (MWA) for early‐stage non‐small cell lung cancer (NSCLC). However, few studies have focused on patients aged 80 years and older. This retrospective study aimed to evaluate the safety and clinical outcomes of CT‐guided percutaneous MWA in patients aged 80 years and older with early‐stage peripheral NSCLC. Methods A retrospective analysis of 63 patients aged 80 years and older with cT1a‐2bN0M0 peripheral NSCLC who underwent CT‐guided percutaneous MWA was performed between January 2008 and January 2018 at 11 hospitals in Shandong Province, China. Results The median follow‐up time was 21.0 months. The overall median survival time was 50 months. The cancer‐specific median survival time was not reached in five years. The one‐, two‐, three‐, four‐, and five‐year overall survival rates were 97.1%, 92.6%, 63.4%, 54.4%, and 32.6%, respectively. The one‐, two‐, and three‐year cancer‐specific survival (CSS) rates were 97.9%, 97.9%, and 69.4%, respectively. The four‐ and five‐year CSS rates were not achieved. A total of 14 patients (22.2%) had local progression. The one‐, two‐, three‐, four‐, and five‐year local control rates were 88.8%, 78.8%, 70.3%, 63.9%, and 63.9%, respectively. The mortality rate was 0% within 30 days after the procedure. Major complications included pneumothorax requiring drainage (21.1%), pulmonary infection (4.2%), and pleural effusions requiring drainage (2.8%). Conclusions CT‐guided percutaneous MWA is a safe and effective modality for treating patients aged 80 years and older with early‐stage peripheral NSCLC.

Abstract
BACKGROUND Microwave ablation (MWA) is an effective minimally invasive technique for lung tumours. We aim to evaluate its role for pulmonary oligorecurrence after radical surgery of non-small-cell lung cancer (NSCLC). METHODS From June 2012 to Jan 2020, a total of 103 patients with pulmonary oligorecurrence after previous radical surgical resection of NSCLC were retrospectively analysed. The primary endpoint was postoperative progression-free survival (PFS). Secondary endpoints were postoperative overall survival (OS), patterns of failure, complications and predictive factors associated with prognosis. RESULTS Of the 103 patients identified, 135 pulmonary oligorecurrences developed at a median interval of 34.8 months. In total, 143 sessions of MWA were performed to ablate all the nodules. The median PFS and OS were 15.1 months and 40.6 months, respectively. After MWA, 15 (14.6%) patients had local recurrence as the first event, while intrathoracic oligorecurrence and distant metastases were observed in 45 (43.7%) and 20 (19.4%) patients, respectively. In the multivariate analysis, local recurrence and intrathoracic oligorecurrence were not significant predictors for OS (P = 0.23 and 0.26, respectively). However, distant metastasis was predictive of OS (HR = 5.37, 95% CI, 1.04-27.84, P = 0.04). CONCLUSION MWA should be considered to be an effective and safe treatment option for selected patients with pulmonary oligorecurrence after NSCLC radical surgical resection.

Local Thermal Ablation with Continuous EGFR Tyrosine Kinase Inhibitors for EGFR-Mutant Non-small Cell Lung Cancers that Developed Extra-Central Nervous System (CNS) Oligoprogressive Disease. Cardiovasc Intervent Radiol 2019; 42:693-699. [PMID: 30701290 DOI: 10.1007/s00270-018-02153-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Accepted: 12/21/2018] [Indexed: 12/28/2022] [Imported: 10/16/2023]
Abstract
BACKGROUND Most epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) patients treated with tyrosine kinase inhibitors (TKIs) experience oligoprogressive disease. Local ablation for isolated resistant sites continued with the original EGFR-TKI showed good efficacy in these patients. We conducted this multicenter retrospective study to investigate the potential benefit of thermal ablation in NSCLC patients that developed extra-central nervous system (CNS) oligoprogressive disease during TKI treatment. METHODS A total of 71 EGFR-mutant patients treated with EGFR-TKIs were identified. Progression-free survival 1 (PFS1) was calculated from the initiation of TKI treatment to first progression. Patients with metastatic sites ≤ 3 in less than 3 extra-CNS organs suitable for local ablation therapy received either radiofrequency ablation or microwave ablation to these sites and continued on the original TKIs. PFS2 was defined from the first progression to second progression after ablation. RESULTS The median PFS1 for all patients was 11.8 months. Eighty extra-CNS oligoprogressive lesions in 71 patients were ablated. Thirty-six of 71 patients progressed after thermal ablation and 31 of whom died during the study period. The median PFS2 after thermal ablation was 10.0 months, and the median overall survival was 26.4 months. PFS1 and PFS2 were highly correlated with OS, whereas PFS1 was not correlated with PFS2. The numbers of oligoprogressive lesions were significantly and independently associated with PFS2. CONCLUSION Local thermal ablation for the oligoprogressive lesions with continuous EGFR-TKI treatment is associated with additional 10 months of disease control and should be recommended in TKI acquired resistant-NSCLC patients.

Abstract
Purpose: Patients with oligometastatic non-small-cell lung cancer (NSCLC) benefit from local control treatments such as surgery or irradiation. The efficacy and safety of microwave ablation (MWA) in these patients was unknown. Material and methods: Between January 2011 and April 2018, eligible patients were retrospectively enrolled. MWA was conducted for both primary lesions and metastatic lesions in patients with synchronous metastases and in metastatic lesions for patients with metachronous metastases. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were overall survival (OS), technical success, technique efficacy, and complications. Results: Seventy-nine patients with 103 oligometastatic lesions were enrolled. A total of 20 primary lesions and 96 metastatic lesions were treated with MWA during 101 procedures. Technical success was achieved in all patients. Technique efficacy was achieved in 72 patients (91.1%). The median PFS and OS were 14.0 and 47.8 months, respectively. Forty-four patients (55.7%) developed complications with 21 (29.6%) of these patients developing major complications. All complications were resolved via appropriate medical treatments, and no MWA-related deaths occurred. Conclusion: MWA was safe and effective for patients with oligometastatic NSCLC.

Abstract
Surgery remains the first choice of cure for early stage lung cancer. However, many patients are diagnosed at advanced stage, and thus miss the opportunity to undergo surgery. As such patients derive limited benefits from chemotherapy or radiotherapy, alternatives focusing on local control have emerged, including iodine-125 seed implantation. The Interstitial Brachytherapy Society, Committee of Minimally Invasive Therapy in Oncology, Chinese Anti-Cancer Association organized a group of multidisciplinary experts to develop guidelines for this treatment modality. These guidelines aim to standardize iodine-125 seed implantation procedures, inclusion criteria, and outcome assessment to prevent and manage procedure-related complications.
