Abstract
OBECTIVE The aim of this study was to report outcomes following percutaneous microwave and cryoablation of lung metastases from adenoid cystic carcinoma (ACC) of the head and neck. MATERIAL AND METHODS This bi-institutional retrospective cohort study included 10 patients (6 females, median age 59 years [range 28-81]) who underwent 32 percutaneous ablation sessions (21 cryoablation, 11 microwave) of 60 lung metastases (median 3.5 tumors per patient [range 1-16]) from 2007 to 2019. Median tumor diameter was 16 mm [range 7-40], significantly larger for cryoablation (22 mm, p = 0.002). A median of two tumors were treated per session [range 1-7]. Technical success, local control, complications, and overall survival were assessed. RESULTS Primary technical success was achieved for 55/60 tumors (91.7%). Median follow-up was 40.6 months (clinical) and 32.5 months (imaging, per tumor). Local control at 1, 2, and 3 years was 94.7%, 80.8%, and 76.4%, respectively, and did not differ between ablation modalities. Five of fifteen recurrent tumors underwent repeat ablation, and secondary technical success was achieved in four (80%). Assisted local tumor control at 1, 2, and 3 years was 96.2%, 89.8%, and 84.9%, respectively. Complications occurred following 24/32 sessions (75.0%) and 57.2% Common Terminology Criteria for Adverse Events (CTCAE) lower than grade 3. Of 13 pneumothoraces, 7 required chest tube placements. Hemoptysis occurred after 7/21 cryoablation sessions, and bronchopleural fistula developed more frequently with microwave (p = 0.037). Median length of hospital stay was 1 day [range 0-10], and median overall survival was 81.5 months (IQR 40.4-93.1). CONCLUSION Percutaneous computed tomography-guided microwave and cryoablation can treat lung metastases from ACC of the head and neck. Complications are common but manageable, with full recovery expected.

Role of Thermal Ablation in Colorectal Cancer Lung Metastases. Cancers (Basel) 2021; 13:cancers13040908. [PMID: 33671510 PMCID: PMC7927065 DOI: 10.3390/cancers13040908] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 02/13/2021] [Accepted: 02/18/2021] [Indexed: 12/30/2022] Open
Abstract
Simple Summary For a long time, surgery has been the only local treatment for pulmonary metastases. Percutaneous thermal ablation appeared in the early 2000s as a minimally invasive alternative technique to surgery for patients who were not eligible for surgery or wanted to preserve quality of life. In this review, we discuss the role of thermal ablation in the management of lung metastases of colorectal cancer, and present the main results of the literature concerning oncological outcomes (local tumor control, survival) based on 12 relevant original studies each involving a minimum of 50 patients, with a minimal follow-up of 12 months. Abstract Background: Consensus guidelines of the European Society for Medical Oncology (ESMO) (2016) provided recommendations for the management of lung metastases. Thermal ablation appears as a tool in the management of these secondary pulmonary lesions, in the same manner as surgical resection or stereotactic ablative radiotherapy (SABR). Methods: Indications, technical considerations, oncological outcomes such as survival (OS) or local control (LC), prognostic factors and complications of thermal ablation in colorectal cancer lung metastases were reviewed and put into perspective with results of surgery and SABR. Results: LC rates varied from 62 to 91%, with size of the metastasis (<2 cm), proximity to the bronchi or vessels, and size of ablation margins (>5 mm) as predictive factors of LC. Median OS varied between 33 and 68 months. Pulmonary free disease interval <12 months, positive carcinoembryonic antigen, absence of neoadjuvant chemotherapy and uncontrolled extra-pulmonary metastases were poor prognostic factors for OS. While chest drainage for less than 48 h was required in 13 to 47% of treatments, major complications were rare. Conclusions: Thermal ablation of a selected subpopulation of patients with colorectal cancer lung metastases is safe and can provide excellent LC and delay systemic chemotherapy.

Abstract
OBJECTIVES The prediction of postoperative preserved pulmonary function is essential for ascertaining the functional operability of pulmonary metastasectomy candidates. Formulae to predict pulmonary function after metastasectomy have not yet been described. This study was undertaken to provide data about the functional loss after a pulmonary metastasectomy, which often includes non-anatomical resections or combinations with anatomical resections. METHODS Pulmonary function tests were performed preoperatively, postoperatively and 3 months after a pulmonary metastasectomy, and the factors potentially influencing the functional outcome were prospectively collected in a database. The functional loss was calculated as the difference in the values between the follow-up visit and the preoperative values, and the influencing factors were tested using the Mann-Whitney test. RESULTS A total of 162 patients were prospectively included in the study and 117 completed the study protocol with a follow-up evaluation after a mean of 3.4 months. Of these, 33 patients had bilateral resections, 30 interventions were repeated resections and adhesions were removed in 46. The greatest lung resection performed was a lobectomy in 13, with segmentectomy in 27 and wedge resection in 77 patients. The mean overall functional loss was: forced vital capacity -9.2%, total lung capacity -8.8%, forced expiratory volume in 1 s -10.8% and diffusion capacity for carbon monoxide (DLCO) -9.7%, whereas the diffusion coefficient (KCO) and pO(2) remained unchanged after 3 months. This functional loss was significant (P < 0.001) for all the parameters mentioned. The two factors were inversely found to influence the functional outcome: bilateral resection reduced spirometry values (P < 0.01), postoperative chemotherapy reduced DLCO (P = 0.011) and KCO (P = 0.029). CONCLUSIONS A pulmonary metastasectomy leads to a significant loss of pulmonary function after 3 months in an average patient collective. The most important factors for deteriorating lung function are a bilateral operation and postoperative chemotherapy.

Abstract
BACKGROUND Pulmonary metastasectomy with lung-sparing local excisions is a widely accepted method of treating stage IV malignancies in selected cases. The ability to predict postoperative lung function is an unresolved issue, especially when multiple wedge resections are planned. To help develop a method to predict postoperative lung function after wedge resections, we present this prospective observational study. METHODS A total of 77 patients who underwent one or more wedge resections to remove lung metastases completed the study protocol. Spirometry results, diffusion capacity of lung for carbon monoxide (Dlco), and blood gases and potential confounding factors were measured prior to, immediately following, and 3 months after the procedure and were analyzed. RESULTS Seventy-seven patients with a median age of 61.3 years underwent up to 22 wedge resections. The mean lung function losses were FVC (-7.5%), total lung capacity (TLC) (-7.9%), FEV(1) (-9.2%), and Dlco (-8.8%), and all were statistically significant (P < .001). The lung function losses also differed significantly between those having a single and those with more than eight wedge resections. Using regression analysis, we found that for every additional wedge resection, there was a reduction in FVC of 30 mL (0.7%), in TLC of 44 mL (0.65%), and in FEV(1) of 23 mL (0.58%). CONCLUSIONS Metastasectomy by wedge resection significantly reduces lung function parameters. As a benchmark, we can predict a 0.6% decrease in spirometry values and Dlco for every additional wedge resection, and a decrease of approximately 5% that may be attributed to thoracotomy.

Abstract
PURPOSE OF REVIEW Secondary spontaneous pneumothorax (SSP) can occur in patients who are suffering from diffuse lung disease. The main cause of SSP is chronic obstructive pulmonary disease (COPD). In contrast to primary spontaneous pneumothorax, SSP is a potentially life-threatening condition because patients with SSP also have limited cardiopulmonary reserve. Prompt diagnosis and treatment of SSP are mandatory. In this review, thoracoscopy, a less invasive surgical treatment for SSP, is discussed from the viewpoint of postoperative morbidity, mortality, and recurrence of SSP. RECENT FINDINGS A meta-analysis showed that postoperative recurrence of pneumothorax is more frequently observed following thoracoscopy than following open thoracotomy. Recent studies on thoracoscopic surgery for SSP have shown that the rate of postoperative morbidity is still high (15-27.7%) and thoracoscopy is sometimes replaced with open thoracotomy because of dense pleural adhesion or inability to maintain one-lung ventilation during surgery. However, many thoracic surgeons prefer to perform thoracoscopic surgery for SSP because it is less invasive than open thoracotomy. Techniques for bullectomy and pleurodesis are currently being adapted to decrease the recurrence rate of pneumothorax. SUMMARY Thoracoscopic surgery for the treatment of SSP should be less invasive to reduce postoperative morbidity, and it should also be more effective to reduce the recurrence of pneumothorax.

Abstract
The indication for pulmonary metastasectomy has been postulated based on nonrandomized clinical experiences. The postoperative survival rate of selected patients with pulmonary metastasis is acceptable; nevertheless, pulmonary metastasectomy might cure patients if the neoplastic cells are located only in the lung parenchyma. Computed tomography has been the most reliable preoperative diagnostic methods for identifying pulmonary metastasis. However, it has the limitations that small nodules often cannot be detected, or they are overestimated. Through thoracoscopy, which has largely been applied for metastasectomy in Japan, bimanual palpation during surgery cannot be performed. Considering the fact that the survival rate of the patients undergoing thoracoscopy is not significantly different from that of the patients undergoing conventional thoracotomy, pulmonary metastasectomy is a suboptimal method for eradicating the disease. Less invasive local therapy may be promising for repeat local intervention.

Abstract
Metastasectomy is the only curative option for some patients with secondary pulmonary malignancy. Many studies suggest a survival benefit in selected patients if complete resection of pulmonary metastases is accomplished. There are several operative approaches that may be used, with the goal of complete resection and with minimal parenchymal loss. Evaluation for resection must include ascertainment of control of the primary tumor and assessment of the ability to achieve complete resection. Minimally invasive approaches may offer advantages in quality of life outcomes, with equivalent oncologic outcomes.

Is finger palpation at operation indispensable for pulmonary metastasectomy in colorectal cancer? Ann Thorac Surg 2007; 84:1680-4.

Abstract
BACKGROUND The use of thoracoscopic techniques for pulmonary metastasectomy is controversial because small metastatic foci might be missed without thorough finger palpation of the lung. METHODS We retrospectively examined preoperative findings of helical computed tomography and pathologic findings of pulmonary nodules obtained by open thoracotomy, including median sternotomy or thoracoscopy, in patients thought to have pulmonary metastasis from colorectal cancer. RESULTS We performed 122 pulmonary metastasectomies (43 thoracotomies and 79 thoracoscopies) in 102 patients from 1999 to 2005. Repeat metastasectomies were excluded. Preoperative evaluation revealed 219 pulmonary nodules suspicious for pulmonary metastasis, and 250 nodules were resected; however, pathologic examination revealed that 47 (18.8%) of 250 nodules were not metastases. When the diameters of the pulmonary nodules were small, the rates of metastasis were also significantly lower. Finally, 4 thoracotomy (9.3%) and 5 thoracoscopy patients (6.3%) were found to have additional pulmonary metastases at operation. Recurrent pulmonary metastases were found at the ipsilateral side of the metastasectomy in 27 (34.2%) of 79 thoracoscopies and 27 (62.8%) of 43 open thoracotomies (p = 0.0023) within 2 years after the pulmonary surgery. These metastatic foci might have been missed at the time of pulmonary metastasectomy. CONCLUSIONS The ability to detect pulmonary metastases in patients with colorectal cancer is limited by preoperative evaluation with computed tomography and surgical techniques, including open thoracotomy with bimanual palpation. Pulmonary metastasectomy by open thoracotomy or thoracoscopy may be a suboptimal intervention to remove metastatic foci in the lungs.

Abstract
This article summarizes findings about the applicability of minimal-access techniques for thoracic and upper gastrointestinal cancers, including those affecting the lung, liver, stomach, and adrenal gland. If metastasectomy and cytoreductive surgery are rapidly evolving, minimal-access surgery in this setting is in its introductory stages. Nevertheless, minimal-access metastasectomy and cytoreductive surgery harbor great potential for selected patients, but further clinical studies are needed.

Abstract
Therapeutic pulmonary metastectomy is accepted therapy for pulmonary metastases. However, more than 50% of patients who undergo this treatment will experience recurrences, many within the same lobe. Minimally invasive approaches provide an option for therapy that minimizes morbidity and, in the case of RFA, preserves pulmonary function. The long-term results of RFA, even for non-small cell lung cancer, are not yet determined. Resection using a VATS or open approach should continue to remain the standard of care.
