[PMID: 35585903 PMCID: PMC9108527 DOI: 10.1016/j.rmcr.2022.101664] [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: 01/11/2022] [Revised: 03/28/2022] [Accepted: 04/29/2022] [Indexed: 12/02/2022] Open
Abstract
The number of cases with Mycobacterium avium and Mycobacterium intracellulare lung diseases (Mycobacterium avium complex lung disease [MACLD]) are increasing globally. Lung cancer can sometimes present as a comorbidity with MACLD; however, the clinical presentation and outcomes of comorbid MACLD following lung cancer resection remain unclear. Therefore, we retrospectively assessed 17 patients with MACLD undergoing lung cancer resection to determine the impact of lung cancer surgery on comorbid MACLD. Of the 17 patients, Mycobacterium avium and Mycobacterium intracellulare were present in 15 and 2 patients, respectively; 14 patients had stage I lung cancer and underwent lobectomy. Ten patients were postoperatively observed for MACLD without any further intervention, five patients underwent additional resection for conspicuous MACLD lesions, and the remaining two patients underwent complete resection for MACLD and lung cancer within the same lobe followed by rifampicin, ethambutol, and clarithromycin (RECAM) therapy. Seven patients exhibited postoperative MACLD exacerbation, six of whom developed exacerbation in the operated ipsilateral residual lobes. Six of these seven patients received RECAM, three of whom (43%) subsequently exhibited improvement. Attention should be paid to MACLD exacerbation during postoperative follow-up, especially in ipsilateral lobes. Although RECAM therapy may be beneficial in alleviating MACLD exacerbation, further investigation is warranted to validate these results.

[PMID: 35015864 PMCID: PMC9070477 DOI: 10.1093/icvts/ivab350] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 10/22/2021] [Accepted: 11/20/2021] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES The aim of this study was to investigate the risk factors for acute exacerbation (AE) of interstitial lung disease (ILD) following lung cancer resection. METHODS We performed a literature screening on the databases including PubMed, Embase, Ovid MEDLINE® and the Web of Science for related studies published up to January 2021. Eligible studies were included and data on risk factors related to postoperative AE were extracted. All analyses were performed with random-effect model. RESULTS A total of 12 studies of 2655 lung cancer patients with ILD were included in this article. The meta-analysis indicated that male [odds ratios (ORs) = 1.78, 95% confidence interval (CI): 1.02-3.11, P = 0.041], usually interstitial pneumonia pattern on CT (OR = 1.52, 95% CI: 1.06-2.17, P = 0.021), Krebs von den Lungen-6 [standardized mean difference (SMD) = 0.50, 95% CI: 0.06-0.94, P = 0.027], white blood cell (SMD = 0.53, 95% CI: 0.12-0.93, P = 0.010), lactate dehydrogenase (SMD = 0.47, 95% CI: 0.04-0.90, P = 0.032), partial pressure of oxygen (weighted mean difference = -3.09, 95% CI: -5.99 to -0.19, P = 0.037), surgery procedure (OR = 2.31, 95% CI: 1.42-3.77, P < 0.001) and operation time (weighted mean difference = 28.26, 95% CI: 1.13-55.39, P = 0.041) were risk factors for AE of ILD following lung cancer resection. CONCLUSIONS We found that males, usually interstitial pneumonia pattern on CT, higher levels of Krebs von den Lungen-6, lactate dehydrogenase, white blood cell, lower partial pressure of oxygen, greater scope of operation and longer operation time were risk factors for AE of ILD following lung cancer resection. Patients with these risk factors should be more prudently selected for surgical treatment and be monitored more carefully after surgery.

Abstract
INTRODUCTION Video-assisted thoracoscopic surgery (VATS) techniques permit shorter postoperative length of stay (LOS). However, it remains unknown whether earlier discharge increases the risk of adverse postoperative events. We examined whether shorter LOS following elective VATS lung resection was associated with increased rates of readmission or postoperative complications. METHODS Patients who underwent elective thoracoscopic segmentectomy, lobectomy, or bilobectomy for lung neoplasms from 2011 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) dataset. Postoperative LOS was treated as an ordinal variable. The examined outcomes were 30-d readmission and 30-d postdischarge death or serious morbidity (DSM). Multivariable logistic regression models evaluated the association of LOS with outcomes. The most common readmission diagnoses were identified for each operation. RESULTS Among 14,418 patients, 12,410 (86.1%) underwent lobectomy, 1764 (12.2%) underwent segmentectomy, and 244 (1.7%) underwent bilobectomy. The median LOS was 3 d for patients undergoing lobectomy (IQR 2-5) and segmentectomy (IQR 2-4), and 4 d for bilobectomy (IQR 3-6). Readmission rates varied with admission time and ranged from 5.0% for patients with LOS ≤1 d to 8.5% for LOS ≥5 d. The most common readmission diagnoses were pneumothorax (19.0%) and wound complications (13.4%). Each one-day increase in LOS was associated with an increased risk of readmission (OR 1.10, 95% CI 1.04-1.17, P < 0.001). No association was seen between earlier discharge and DSM (OR 1.08, 95% CI 0.99-1.18, P = 0.070). CONCLUSIONS Early discharge following VATS lung resection is not associated with increased rates of readmission or postoperative complications among patients undergoing surgery for cancer, and may safely be considered for selected patients with uncomplicated postoperative recovery.

Abstract
OBJECTIVES Solitary pulmonary capillary haemangioma (SPCH) is a benign lung tumour that presents as ground-glass nodules on computed tomography (CT) images and mimics lepidic-predominant adenocarcinoma. This study aimed to establish a discriminant model using a radiomic feature analysis to distinguish SPCH from lepidic-predominant adenocarcinoma. METHODS In the adenocarcinoma group, all tumours were of the lepidic-predominant subtype with high purity (>70%). A classification model was proposed based on a two-level decision tree and 26 radiomic features extracted from each segmented lesion. For comparison, a baseline model was built with the same 26 features using a support vector machine as the classifier. Both models were assessed by the leave-one-out cross-validation method. RESULTS This study included 13 and 49 patients who underwent complete resection for SPCH and adenocarcinoma, respectively. Two sets of features were identified for discrimination between the 2 different histology types. The first set included 2 principal components corresponding to the 2 largest eigenvalues for the root node of the two-level decision tree. The second set comprised 4 selected radiomic features. The area under the receiver operating characteristic curve, accuracy, sensitivity, specificity were 0.954, 91.9%, 92.3% and 91.8% in the proposed classification model, and were 0.805, 85.5%, 61.5% and 91.8% in the baseline model, respectively. The proposed classification model significantly outperformed the baseline model (P < 0.05). CONCLUSIONS The proposed model could differentiate the 2 different histology types on CT images, and this may help surgeons to preoperatively discriminate SPCH from adenocarcinoma.

Abstract
Purpose Patient-reported outcome measures, including satisfaction with treatment decisions, provide important information in addition to clinical outcomes, survival and decision-making in lung cancer surgery. We investigated associations between preoperative clinical and socio-demographic factors and patient-reported satisfaction 6 weeks after radical treatment for early-stage non-small cell lung cancer (NSCLC). Methods We conducted a sub-group analysis of the prospective observational longitudinal study of 225 participants in two treatment groups—surgical (VATS) and radiotherapy (SABR). The Patient Satisfaction Questionnaire-18 (PSQ-18) was used to measure patient satisfaction 6 weeks after treatment. Clinical variables, Index of Multiple Deprivation decile and Decision self-efficacy scores were used in regression analysis. Variables with a p level < 0.1 were used as independent predictors in generalised linear logistic regression analyses. Results As expected, the two groups differed in pre-treatment clinical features. The SABR group experienced more grade 1–2 complications than the VATS group. No differences were found between the groups in any subscale of the PSQ-18 questionnaire. Patients experiencing complications or living in more deprived areas were more satisfied with care. Properative factors independently associated with patient satisfaction were the efficacy in decision-making and age. Conclusion We showed that efficacy in treatment decision-making and age was the sole predictor of patient satisfaction with their care after radical treatment for early-stage NSCLC. Patients from more deprived areas and patients who suffered complications reported greater subsequent satisfaction. Involving patients in their care may improve satisfaction after treatment for early-stage NSCLC.

Abstract
BACKGROUND Although minimally invasive surgery has been widely carried out at present, the postoperative pain of patients with lung cancer is still one of the difficult problems to solve in clinical practice. OBJECTIVE This study explored whether indwelling pigtail catheters after lung cancer surgery can help to reduce postoperative pain and promote the recovery of patients as soon as possible. MATERIALS AND METHODS From June 2018 to June 2020, patients who underwent thoracoscopic radical resection of lung cancer in our hospital were randomly divided into 2 groups: the pigtail catheter group and the control group. We compared the postoperative time of thoracic catheter removal, postoperative pain score, proportion of postoperative pleural effusion, postoperative hospitalization time, and postoperative complications of the 2 groups. RESULTS A total of 1375 patients were enrolled, including 677 patients in the pigtail catheter group and 698 patients in the control group. Compared with the control group, the pigtail catheter group had an earlier time of thoracic catheter removal, lower postoperative pain score, lower proportion of pleural effusion diagnosed by postoperative chest radiograph, and shorter postoperative average hospital stay, but there was no significant difference in postoperative complications. CONCLUSION The application of pigtail catheters after radical resection of lung cancer can reduce postoperative pain, accelerate the recovery of patients and shorten the postoperative hospital stay and is safe and reliable in clinical application.

Abstract
After thoracic aortic replacement, extensive adhesions are expected to develop between the prosthesis and the lung. There have been no definitive reports on anatomical lung resection performed in patients with left lung cancer after thoracic aortic replacement. Herein, we report a series of five such cases. Our findings showed that severe adhesions were encountered after aortic arch and descending aortic replacement, but not after ascending aortic replacement. We think that these adhesions started developing in the early postoperative period and were particularly severe in the case of left upper lobe lung cancer after arch replacement. However, anatomical lobectomy and systematic lymph node dissection could still be performed safely by devising a surgical technique. In addition, there was a possibility that a new aortic aneurysm may have occurred at the time of surgery. Therefore, it is important to perform a thorough preoperative evaluation and coordinate with the cardiovascular surgery department.

Abstract
OBJECTIVES The aim of this study was to assess whether quality of life (QoL) scales are associated with postoperative length of stay (LoS) following video-assisted thoracoscopic surgery (VATS) lobectomy for lung cancer. METHODS This is a single-centre retrospective analysis on 250 consecutive patients submitted to VATS lobectomies (233) or segmentectomies (17) over a period of 3 years. QoL was assessed in all patients by the self-administration of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 questionnaire. The individual QoL scales were tested for possible association with LoS along with other objective baseline and surgical parameters using univariable and multivariable analyses. RESULTS Thirty-day cardiopulmonary and mortality rates were 22% and 2.4%. The median LoS was 4 days [interquartile range (IQR) 3-7]. Fifty-one (20%) patients remained in hospital longer than 7 days after surgery (upper quartile). General health [global health score (GHS)] (P = 0.019), physical function (P = 0.014) and role functioning (P = 0.016) scales were significantly worse in patients with prolonged stay. They were highly correlated between each other and tested separately in different logistic regression analyses. The best model resulted the one containing GHS (P = 0.032) along with age, low force expiratory volume in 1 s and carbon monoxide lung diffusion capacity and history of cerebrovascular disease. Fifty-nine patients had GHS <58 (lower interquartile value). Thirty-one percent of them experienced prolonged hospital stay (vs 17% of those with higher GHS, P = 0.027). CONCLUSIONS Preoperative patient-reported QoL was associated with prolonged postoperative hospital stay. Baseline QoL status should be taken into consideration to implement psychosocial supportive programmes in the context of enhanced recovery after surgery.

Abstract
Cardiovascular comorbidities often prevent patients with otherwise resectable early-stage lung cancer from undergoing surgery due to prohibitive peri-operative risk. Here we describe the first intraoperative use of venoarterial (VA) ECMO in a stage cIIA lung cancer patient with arterial infiltration and severe post-ischemic dilated cardiomyopathy (EF 23%) undergoing left upper lobectomy with pulmonary artery angioplasty. Providing intra-operative cardiovascular and respiratory function support, VA-ECMO represents a suitable option for patients with heart failure, ensuring adequate hemodynamic profile and reducing the risk of complications. These otherwise inoperable patients can thus be offered a potentially curative surgical resection of the malignancy. Surgery is the standard treatment for patients with early-stage lung cancer 1. However, several patients with advanced heart failure may be excluded from surgery due to prohibitive perioperative risk. Providing circulatory and respiratory support, extracorporeal membrane oxygenator (ECMO) may represent a suitable option for such patients 2. While there is a published experience on intraoperative use of veno-venous (VV) ECMO, primarily in thoracic surgery 3, an extremely limited number of reports considered the use of venoarterial (VA)-ECMO in patients undergoing non-cardiac surgery 45. VA-ECMO is currently indicated in patients with cardiovascular failure and concomitant cardiac pump dysfunction, as in post-operative ARDS associated with septic shock 4; outside the intensive care unit, the use of pre-emptive VA-ECMO has traditionally been limited to patients undergoing elective ventricular tachycardia ablation and structural heart procedures5. Here we report the first case of intraoperative use of VA-ECMO in a patient with resectable lung cancer and ischemic heart disease with prohibitive left ventricular function, and describe the benefits of this new indication.

Abstract
The surgical instruments used in robot-assisted thoracic surgery are flexible to enable the surgeon to approach the surgical field from any direction. However, even in robot-assisted thoracic surgery, subcarinal lymph node dissection requires a precise technique suitable for a small area surrounded by important organs. We present a method of subcarinal node dissection with solo robot-assisted thoracic surgery using bronchial traction method and a metal basket suction device, the Dobon®.

Abstract
Background Primary lung sarcoma (PLS) represents a rare form of lung cancer with outcomes that are poorly defined by small datasets. We sought to characterize clinical and pathological characteristics and associated survival within the surgically managed subgroup of these unusual pulmonary malignancies. Methods We performed a retrospective analysis of the National Cancer Database (NCDB), which was queried for cases of surgically managed PLS diagnosed between 2004–2014. Adjusted mortality was evaluated in a multivariable Cox proportional hazards model and compared to surgically manage non-small cell lung cancer (NSCLC) patients from the same time period. Results A total of 695 patients with surgically managed PLS were identified with 37 different histologic subtypes. The mean age of diagnosis was 57.7 years (range, 18–90 years). A majority of patients underwent surgical resection alone (64.3%) with an estimated 5-year overall survival (OS) of 51%. The multivariable Cox model identified increasing age, Charlson-Deyo score ≥2, high tumor grade, tumor size >5 cm, positive margins, and positive lymph nodes to be associated with higher risk for mortality (P<0.05). Compared to 101,428 surgically managed patients with adenocarcinoma, PLS patients were younger with fewer comorbidities but had larger tumors, higher grade tumors, and were more likely node negative (P<0.001). Surgery with adjuvant chemotherapy was associated with worse survival than surgery alone (HR 1.41, 95% CI: 1.05–1.88). The extent of parenchymal resection (lobar vs. sublobar) was not predictive for survival. Five-year OS was lower for patients with PLS (44%) than adenocarcinoma (53.6%, P<0.001). Conclusions The survival of surgically managed PLS is reasonable and impacted by tumor attributes and the completeness of surgical resection. Further study to define the role of multimodal therapy is indicated.

Abstract
OBJECTIVES The aim of this study was to assess the long-term outcomes of patients treated by anatomical pulmonary resection with the video-assisted thoracoscopic surgery (VATS) approach, VATS requiring intraoperative conversion to thoracotomy or an upfront open thoracotomy for lung cancer surgery. METHODS We performed a retrospective single-centre study that included consecutive patients between January 2011 and December 2018 treated either by VATS (with or without intraoperative conversion) or open thoracotomy for non-small-cell lung cancer (NSCLC). Patients treated for a benign or metastatic condition, stage IV disease, multiple primary lung cancer or by resection, such as pneumonectomies or angioplastic/bronchoplastic/chest wall resections, were excluded. RESULTS Among 1431 patients, 846 were included: 439 who underwent full-VATS, 94 who underwent VATS-conversion (21 emergent, 73 non-emergent) and 313 treated with upfront open thoracotomy. The median follow-up was 37 months. There were no statistical differences in stage-specific overall survival between the full-VATS, VATS-conversion, and open thoracotomy groups, with 5-year OS for stage I NSCLC of 76%, 72.3% and 69.4%, respectively (P = 0.47). There was a difference in disease-free survival for stage I NSCLC, with 71%, 60.2% and 53%, respectively at 5 years (P = 0.013). Fewer complications occurred in the full-VATS group (pneumonia, arrhythmia, length of stay), but complication rates were similar between the VATS-conversion and thoracotomy groups. CONCLUSIONS VATS resection for NSCLC with intraoperative conversion does not appear to alter the long-term oncological outcome relative to full-VATS or open upfront thoracotomy. Postoperative complications were higher than for full-VATS and comparable to those for thoracotomy. VATS should be favoured when possible.

Abstract
Background Repeated assessment of patient recovery after discharge is challenging. This study used a popular messenger application to remotely collect patient self-reported symptoms and their severity so as to monitor patient recovery and identify the factors affecting the recovery of symptoms following lung cancer surgery. Methods This prospective observational study was conducted at a single tertiary lung cancer center in China between November 2018 and June 2019. Participants received demonstration videos and repeated symptom surveys regarding pain and cough severity (assessed using numeric rating scores of 0–10 for pain and 0–6 for cough) at 2, 4, 6, 8, and 12 weeks after discharge via a smartphone program bound to the WeChat application. Patients who responded to at least 3 of the 5 post-discharge surveys were included in this study. The data were analyzed to investigate the symptom recovery and its related factors. Results Of the 826 patients enrolled, 589 (71.3%) responded to at least three surveys. The average pain score reduced from 4.1±2.5 at 2 weeks to 2.2±2.0 at 12 weeks (P<0.001). Factors associated with higher pain severity included the female gender, age over 60 years, thoracotomy, longer operation time (>90 minutes), and prolonged chest tube drainage (>7 days). The average cough score decreased from 2.34±1.30 at 2 weeks to 1.93±1.26 at 12 weeks (P<0.001). Being female and a prolonged operation time (>90 min) were related to increased cough severity. Sublobar resection and limited lymphadenectomy may contribute to lower cough severity post-surgery. Conclusions The messenger application-based remote monitoring successfully collected post-discharge symptom information and identified factors associated with recovery following lung surgery.

Abstract
BACKGROUND Anatomical lung resection offers the best prospect of long-term survival in patients with non-small cell lung cancer (NSCLC). However, some patients with significant dyspnoea, impaired performance status (PS), borderline or poor pulmonary function are considered inoperable and instead referred for radiotherapy, chemotherapy or palliative care. The aims of the study were to determine whether pre-operative pulmonary physiotherapy (Prehab), by improving clinical parameters, (i) makes patients suitable for surgery who were considered inoperable on subjective criteria of dyspnoea >3 and PS >2, and objective criteria of diffusing capacity for carbon monoxide (DLCO) <50%; and (ii) thereby allows them to safely receive curative surgery with reduced morbidity and mortality. METHODS From January 2017 to December 2018 a total of 306 patients were prospectively and sequentially assessed for Prehab and 216 patients with lung cancer studied. Their mean age (95% CI) was 71.7 ± 1.1 years, 50.5% (n = 109) were men and they received Prehab over 39.0 ± 7.0 days averaging 3.1 ± 0.6 sessions. Their dyspnoea scores, PS, level of activity, six minute walk test (6MWT) and frailty index prior to and following Prehab were determined. Following surgery the post-operative length of hospital stay (LOHS), complications and mortality at 30 days, 90 days and 1 year determined. Similar outcomes were determined for (i) high-risk patients with dyspnoea scores >3 and PS >2, and compared with low-risk patients having dyspnoea scores <2 and PS <2 (subjective criteria); and (ii) high-risk patients with DLCO <50% and compared with low-risk patients with DLCO >80% (objective criteria). FINDINGS In the total cohort following Prehab, there was significant improvement in the dyspnoea scores <2 / ≥2 (40%/60% prior to Prehab vs. 65%/35% following Prehab, p = 0.00002), PS <2 / ≥2 (45%/55% prior to vs. 62%/38% following Prehab, p = 0.003), frailty index ≤3 / >3 (49%/51% vs 70%/30%, p = 0.0006), and 6MWT (306.6 ± 6.8 m vs 354.8 ± 52.7 m, p = 0.04). Post-operative major complication rates were 8.7%; median LOHS was 7 (IQR 6) days; hospital mortality at 30 days 1.3%, 90 days 4.7% and 1 year 16%. Using subjective criteria of dyspnoea scores >3 and PS >2, 100% of high-risk patients were considered inoperable. Following optimization with Prehab 84.2% of the high-risk patients were ready to proceed with radical treatment and 52.6% with surgery, and subsequently 42.8% of patients underwent surgery. Likewise, 78.8% of patients with DLCO <50% were considered inoperable. Following Prehab 86.5% of high-risk patients were ready to proceed with radical treatment and 59.1% with surgery, and 54.6% of high-risk patients underwent surgery. In each category there were no significant differences in complications, LOHS or mortality rates between the high-risk and low-risk patients. INTERPRETATION Our prospective study showed that with Prehab there was clinical and statistically significant improvement in the dyspnoea scores, PS, level of activity and frailty, particularly in the high-risk group of patients. Importantly, Prehab made previously inoperable patients operable, allowing them to safely undergo curative lung resection. This strategy helps improve resection rates and may contribute to the long term survival of lung cancer patients.

Screening and topical decolonization of preoperative nasal Staphylococcus aureus carriers to reduce the incidence of postoperative infections after lung cancer surgery: a propensity matched study. Interact Cardiovasc Thorac Surg 2020; 30:552-558. [PMID: 31886854 DOI: 10.1093/icvts/ivz305] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Revised: 11/12/2019] [Accepted: 11/21/2019] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Health care-associated infections (HAIs) are serious issues following lung cancer surgery, leading to an increased risk of morbidity and hospital cost burden. The aim of this study was to evaluate the impact on postoperative outcomes of a preoperative screening and decolonization strategy of nasal carriers for Staphylococcus aureus prior to lung cancer surgery. METHODS We performed a retrospective study comparing 2 cohorts of patients undergoing major lung resection: a control group of patients from the placebo arm of the randomized Clinical Study to Evaluate the Efficacy of Chlorhexidine Mouthwashes operated on between July 2012 and April 2015 without any nasopharyngeal screening (N = 224); an experimental group, with preoperative screening for S. aureus of nasal carriers and selective 5-day decolonization in positive carriers using mupirocin ointment between January 2017 and December 2017 (N = 310). The 2 groups were matched according to a propensity score analysis with 1:1 matching. The primary outcome was the rate of postoperative HAIs, and the secondary outcome was the need for postoperative mechanical ventilation after surgery. RESULTS After matching, 2 similar groups of 108 patients each were obtained. In the experimental group, 26 patients had positive results for nasal carriage, and a significant decrease was observed in the rate of overall postoperative HAIs [control n = 19, 17.6%; experimental group n = 9, 8.3%; P = 0.043; relative risk 0.47 (0.22-1)] and in the rate of postoperative mechanical ventilation [control n = 12, 11.1%; experimental group n = 4, 3.7%; P = 0.038; relative risk 0.33 (0.11-1)]. After logistic regression and multivariable analysis, screening of S. aureus nasal carriers reduced the rate of HAIs [odds ratio (OR) 0.29, 95% confidence interval (CI) 0.11-0.76; P = 0.01] and reduced the risk of the need for postoperative mechanical ventilation (OR 0.19, 95% CI 0.05-0.74; P = 0.02). There was no significant statistical difference between the 2 groups regarding the rate of postoperative S. aureus-associated infection (control group n = 6, 5.6%; experimental group n = 2, 1.9%; P = 0.28). CONCLUSIONS Identification of nasal carriers of S. aureus and selective decontamination using mupirocin appeared to have a beneficial effect on postoperative infectious events after lung resection surgery.

Abstract
OBJECTIVE We investigated on the benefit/risk ratio of surgery in octogenarians with early-stage non-small cell lung cancer (NSCLC). MATERIAL AND METHODS From 2005-2020, 100 octogenarians were operated on for a clinical stage IA to IIA NSCLC. All patients had undergone whole body PET -scan and brain imaging. Operability was assessed according to current guidelines regarding the cardiopulmonary function. Since 2015, patients followed a dedicated geriatric evaluation pathway. Minimally invasive approaches were used in 66 patients, and a thoracotomy in 34. RESULTS Clavien-Dindo grade ≥ 4 complications occurred in 15 patients within 90 days, including 7 fatalities. At multivariable analysis, the number of co-morbidities was their single independent prognosticator. Following resection, 24 patients met pathological criteria for adjuvant therapy among whom 3 (12.5 %) received platinum-based chemotherapy. Five-year survival rates were overall (OS) 47 ± 6.3 %, disease-free (DFS) 77.6 ± 5.1 %, and lung cancer-specific (CSS) 74.7 ± 6.3 %. Diabetes mellitus impaired significantly long-term outcomes in these 3 dimensions. OS was improved since the introduction of a dedicated geriatric assessment pathway (72.3 % vs. 6.4 %, P = 0.00002), and when minimally invasive techniques were used (42.3 % vs. 11.3 %; P = 0.02). CSS was improved by the performance of systematic lymphadenectomy (55.3 % vs. 26.9 %; P = 0.04). Multivariable and recursive partitioning analyses showed that a decision tree could be built to predict overall survival on the basis of diabetes mellitus, high co-morbidity index and low ppoDLCO values. CONCLUSIONS The introduction of a dedicated geriatric assessment pathway to select octogenarians for lung cancer surgery was associated with OS values that are similar to outcomes in younger patients. The use of minimally invasive surgery and the performance of systematic lymphadenectomy were also associated with improved long-term survival. Octogenarians with multiple co-morbid conditions, diabetes mellitus, or low ppo DLCO values may be more appropriately treated with SBRT.

Prevalence of venous thromboembolism after lung surgery in China: a single-centre, prospective cohort study involving patients undergoing lung resections without perioperative venous thromboembolism prophylaxis†. Eur J Cardiothorac Surg 2020; 55:455-460. [PMID: 30289479 DOI: 10.1093/ejcts/ezy323] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2018] [Revised: 08/20/2018] [Accepted: 08/27/2018] [Indexed: 01/24/2023] Open
Abstract
OBJECTIVES Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the incidence of VTE after major thoracic surgery ranges from 2.3% to 15%. However, there have been no such data from China so far. To evaluate the incidence of postoperative VTE, we conducted a single-centre, prospective cohort study. METHODS Patients who underwent lung resections between July 2016 and March 2017 were enrolled in this study. None of the patients received any prophylaxis perioperatively. All patients were screened for deep venous thrombosis (DVT) using non-invasive duplex lower-extremity ultrasonography 30 days before surgery and within 30 days after surgery and before discharge. Chest tomography, pulmonary embolism protocol was carried out if patients had one of the following conditions: (i) typical symptoms of pulmonary embolism, (ii) high Caprini score (≥9 points) and (iii) newly diagnosed postoperative DVT. RESULTS Two hundred and sixty-two patients undergoing lung surgery were enrolled, including 115 benign and 147 malignant disease cases. The procedures included 84 sublobar lung resections, 161 lobectomies, 5 pneumonectomies and 12 mixed procedures. The overall postoperative incidence of VTE was 11.5% (30 of 262). Twenty-four patients were diagnosed with DVT (80.0%) and 6 with DVT + pulmonary embolism (20.0%). None of the patients diagnosed with VTE had obvious symptoms of VTE. The median time for VTE detection was 5 days postoperatively. The incidence of VTE was 7.0% in patients with benign lung diseases and 15.0% in those with malignant lung diseases (P < 0.05). Using the Caprini risk assessment model, 63 cases were scored as low risk, 179 as moderate risk and 20 as high risk, and each group had an incidence of postoperative VTE of 0%, 12.3% (22 of 179) and 40.0% (8 of 20), respectively (P < 0.05). In patients with lung cancer, 98% were moderate or high risk, and only 3 patients were scored in the low risk category. The incidence of VTE in patients at moderate risk and high risk was 12.0% and 36.8%, respectively, while it was 0 in low-risk patients. CONCLUSIONS The following conclusions were drawn: (i) the overall incidence of postoperative VTE after lung surgery without VTE prophylaxis is substantial; (ii) lower-extremity ultrasonography was helpful in detecting asymptomatic DVT in symptomatic or high-risk patients; and (iii) VTE prophylaxis should be considered as a mandatory part of perioperative care.

Abstract
Bronchopleural fistula (BPF) often needs two-stage closure after fenestration. This case highlights one-stage surgical closure of a large BPF with a muscle flap. Pedicled latissimus dorsi muscle flap would be useful even for 3-cm sized BPF. Preemptive antibiotics minimized local infection in ischemic bronchitis before BPF. Minimum infection with a limited-size space may be a key for one-stage closure.
Introduction Bronchopleural fistula (BPF) after lung cancer surgery is a life-threatening complication and often needs two-stage closure after fenestration. Although one-stage closure of BPF is challenging, it would provide shorter treatment time and lower patient physical burden than two-stage closure. However, there have been few reports of one-stage closure of a large BPF. Presentation of case A 53-year-old man underwent robotic right lower lobectomy with systematic lymph node dissection. Postoperative bronchoscopy revealed an ischemic change in the bronchial stump, which progressed to a large BPF. However, under the preemptive antibiotic treatment without chest drainage, local infection was controlled within a limited pleural space. We successfully performed one-stage closure of a 3-cm sized BPF with pedicled latissimus dorsi (PLD) muscle flap. Discussion Early diagnosis of ischemic bronchitis and appropriate preceding antibiotic treatment could minimize the local infection around the fistula. To our knowledge, our case represented the largest BPF that was successfully treated by one-stage procedure using preemptive antibiotics and the PLD muscle flap. Conclusion One-stage closure using the PLD muscle flap may be a treatment option even for a 3-cm sized BPF, wherein infection is controlled and the relevant pleural cavity is limited.

Abstract
Lung resection following pneumonectomy for recurrent lung cancer is a challenging scenario. Peri-operative airway management and choice of surgical procedure are issues to be addressed by both the anesthesiologists and thoracic surgeons. We hereby report a case of anterior segmentectomy of the right upper for recurrent lung cancer, in a patient who had previously underwent pneumonectomy for primary lung cancer one year earlier. A modified conventional tracheal intubation and unique surgical techniques were applied for video-assisted thoracoscopic surgery (VATS) anterior segmentectomy of the right upper lobe in a patient with a notable mediastinal shift (following contralateral pneumonectomy), resulting in a good recovery and clinical outcome. The clinical experience is summarized in detail in this article.

Abstract
BACKGROUND Lung cancer surgery may be required for patients with a history of coronary artery bypass graft (CABG). In this study, we evaluated the general characteristics of patients, the difficulties experienced during and after lung cancer surgery and complications and mortality rates. METHOD Patients who were operated on for primary lung cancer between January 2012 and July 2017 in the participating centres were analysed retrospectively (n=7,530). Patients with a history of CABG (n=220) were examined in detail. This special group was analysed and compared with other patients operated on for lung cancer who did not have CABG (n=7,310) in terms of 30-day mortality and revision for haemorrhage. RESULTS Of the 7,530 patients operated on for primary lung cancer, 2.9% were found to have undergone CABG. Surgical revision was required in the early postoperative period for 6.8% of those who had CABG and 3.5% in those who did not have CABG (p=0.009). Thirty-day (30-day) mortality was 4.5% in those who had CABG and 2.9% in those who did not have CABG (p=0.143). Further analysis of patients who had undergone CABG demonstrated that video-assisted thoracoscopic surgery (VATS) resulted in fewer complications (p=0.015). Patients with a left-sided left internal mammary artery (LIMA) graft had a higher number of postoperative complications (p=0.30). CONCLUSIONS Patients who had CABG suffered postoperative haemorrhage requiring a revision twice as often, and a tendency towards higher mortality (non-statistically significant). In patients with a history of CABG, VATS was demonstrated to have fewer complications. Patients with a LIMA graft who had a left-sided resection had more postoperative complications.

Abstract
OBJECTIVES The influence of surgical approach on systemic inflammatory response and the subsequent oncologic impact for non-small cell lung cancer is debated. We aimed to measure the effects of thoracic surgical approach on peripheral cytokine milieu over time. METHODS Patients undergoing primary lung resection without neoadjuvant therapy (2016-2018) were evaluated. A panel of 43 cytokines, angiogenic factors, and inflammatory molecules (CAFs) were evaluated in peripheral blood preoperatively, at 24 -hs and 4-weeks postoperatively. Differences between CAFs in patients undergoing thoracotomy versus video-assisted thoracoscopic surgery (VATS) at all timepoints were assessed using Student's t-test. RESULTS 76 patients with available peripheral CAF panels met inclusion criteria. Thoracotomy was performed in 53 (70 %) patients while VATS was undertaken in 23 (30 %). Upon examination of known inflammatory CAFs, including IL-1β, IL-6, IL-8, IL-10, IFN-γ, and soluble (s) CD27, no differences were detected at 24 h or 4 weeks postoperatively between surgical groups. Examination of trends over time did not demonstrate any temporal derangements for these CAFs, with return to baseline levels by 4 weeks postoperatively for both groups. Evaluation of soluble (s) checkpoint molecules, including sPD-1, sPD-L1, sTIM-3, and sCTLA-4, did not reveal any differences in the immediate postoperative or long-term recovery period. CONCLUSIONS Peripheral immune profiles following pulmonary resection do not appear to differ between VATS and thoracotomy postoperatively. CAF fluctuations are transient and recover rapidly. These results, at the peripheral cytokine level, suggest that the surgical approach for lung cancer is unlikely to alter the effectiveness of novel immune-modulating systemic therapies, although more studies are needed to validate these findings.

Abstract
BACKGROUND Two different techniques of performing segmentectomy have been reported in the era of video-assisted thoracosopic surgery (VATS), including stapled segmentectomy (SS) and non-stapled segmentectomy (NSS). Some surgeons favor stapled segmentectomy for better pneumostatic control, while others prefer non-stapled segmentectomy to avoid compromising adjacent pulmonary parenchyma. In this study, we used multidetector computed tomography (MDCT) and spirometry to evaluate lung volume preservation of different segmentectomy techniques. METHODS A total of 269 patients undergoing video-assisted thoracic surgery (VATS) segmentectomy between October 2013 and September 2016 in a single institution were reviewed. Perioperative outcomes, the cost of hospital admission, the change in forced expiratory volume in 1 s (FEV1) (ΔFEV1 and ΔFEV1%), and residual ipsilateral volume ratios (RiVR) were compared. RESULTS The final study population consisted of 107 patients: 30 patients underwent NSS, and 77 patients underwent SS. The NSS group had significantly longer operative time, more blood loss, longer duration of chest tube placement and postoperative hospitalization than the SS group. The follow-up of RiVR (at 6 months, 12 months, 24 months), ΔFEV1(L), and ΔFEV1(%) demonstrated no significant difference between NSS and SS group. CONCLUSION Our study demonstrated that postoperative residual lung volume was not influenced by different segmentectomy techniques.

Study protocol for a multicenter randomized controlled trial. BMC Pulm Med 2020; 20:44.

Abstract
BACKGROUND Lung cancer surgery is associated with a high incidence of postoperative pulmonary complications (PPCs). Preliminary evidence suggests that ERAS processes can reduce overall incidence of PPCs as short- and long-term recovery improved by supporting units to adopt evidence-based care. However, the evidence is inconclusive due to insufficient high-level studies in this research field. No well-designed, adequately powered, randomized controlled trials (RCTs) have investigated the effects of pulmonary rehabilitation based ERAS program (PREP) on post-operative pulmonary complications, pulmonary function, and health related quality of life following lung cancer surgery. METHODS The PREP trial is a pragmatic, investigator-initiated, multi-center, randomized controlled, parallel group, clinical trial. Five hundred patients scheduled for minimally invasive pulmonary resection at six hospitals in China will be randomized with concealed allocation to receive either i) a pre-operative assessment and an information booklet or ii) a pre-operative assessment, an information booklet, plus an additional education, a 30-min pulmonary rehabilitation training session and the post-operative pulmonary rehabilitation program. The primary outcome is incidence of PPCs defined with the Melbourne Group Scale diagnostic scoring tool. Secondary outcomes include incidence of cardiopulmonary and other complications, pulmonary function, cardiopulmonary endurance, muscle strength, activity level, health-related quality of life (HRQoL), pre- and post-operative hospital length of stay (LOS), and total hospital LOS. DISCUSSION The PREP trial is designed to verify the hypothesis that pulmonary rehabilitation based ERAS program reduces incidence of PPCs and improves pulmonary function and HRQoL in patients following lung cancer surgery. This trial will furthermore contribute significantly to the limited knowledge about the pulmonary rehabilitation based ERAS program following lung cancer surgery, and may thereby form the basis of future recommendations in the surgical community.

Abstract
Background Recently sublobar resection is often indicated for small-sized peripheral lung cancer according to size or the consolidation/tumor ratio on CT; however, the T-factor classification drastically changed in the 8th version. We investigated the relationship between a novel clinical T-factor classification, which includes other clinical information and the pathologic N-factor, to evaluate the applicability of the novel T-factor classification to sublobar resection. Methods From January 2013 to October 2017, 545 patients with cTis or cT1 lung cancer underwent surgery. Patients with non-peripheral type, induction treatment, cN≥1, cM1, and those without nodal dissection, preoperative evaluation by thin-sliced CT or FDG-PET were excluded. Finally, 325 patients were eligible for inclusion. All clinical parameters were prospectively collected and retrospectively analyzed. The 8th edition of TNM classification was utilized. Results Nodal metastasis was detected in 38 (11.7%) patients. Among cTis/1mi/1a/1b/1c patients (n=10/11/51/146/107), pN1 and pN2 were observed in 0/0/2/9/10 and 0/0/1/8/8, respectively. cT1b/c patients showed a significantly higher rate of nodal metastasis (P=0.024). Among 253 cT1b/c patients, solid-type tumors (n=177) were more frequently associated with nodal metastasis. A ROC curve analysis revealed that SUVmax 1.9 was the cutoff value (AUC=0.827) for the presence of nodal metastasis. Using the 2 parameters of solid-type or SUVmax ≥1.9, we could successfully exclude patients with nodal metastasis, for whom sublobar resection is not indicated. Conclusions In terms of nodal metastasis, sublobar resection can be applicable for all cTis/1mi tumors; patients with cT1a/b/c tumors with mixed GGO and low SUVmax are candidates for sublobar resection.
