Enhanced recovery after chest wall resection and reconstruction: a clinical practice review.

Since the late 1990s, and Henrik Kehlet's hypothesis that a reduction of the body's stress response to major surgeries could decrease postoperative morbidity, "Enhanced Recovery After Surgery" (ERAS) care pathways have been streamlined. They are now well accepted and considered standard in many surgical disciplines. Yet, to this day, there is no specific ERAS protocol for chest wall resections (CWRs), the removal of a full-thickness portion of the chest wall, including muscle, bone and possibly skin. This is most unfortunate because these are high-risk surgeries, which carry high morbidity rates. In this review, we propose an overview of the current key elements of the ERAS guidelines for thoracic surgery that might apply to CWRs. A successful ERAS pathway for CWR patients would entail, as is the standard approach, three parts: pre-, peri- and postoperative elements. Preoperative items would include specific information, targeted patient education, involvement of all members of the team, including the plastic surgeons, smoking cessation, dedicated nutrition and carbohydrate loading. Perioperative items would likely be standard for thoracotomy patients, namely carefully selective pre-anesthesia sedative medication only in some rare instances, low-molecular-weight heparin throughout, antibiotic prophylaxis, minimization of postoperative nausea and vomiting, avoidance of fluid overload and of urinary drainage. Postoperative elements would include early mobilization and feeding, swift discontinuation of intravenous fluid supply and chest tube removal as soon as safe. Optimal pain management throughout also appears to be critical to minimize the risk of respiratory complications. Together, all these items are achievable and may hold the key to successful introduction of ERAS pathways to the benefit of CWR patients.

Local control and short-term outcomes after video-assisted thoracoscopic surgery segmentectomy versus lobectomy for pT1c pN0 non-small-cell lung cancer.

OBJECTIVES: The aim of this study was to compare short-term outcomes and local control in pT1c pN0 non-small-cell lung cancer that were intentionally treated by video-assisted thoracoscopic surgery (VATS) lobectomy or segmentectomy. METHODS: Multicentre retrospective study of consecutive patients undergoing VATS lobectomy (VL) or VATS segmentectomy (VS) for pT1c pN0 non-small-cell lung cancer from January 2014 to October 2021. Patients' characteristics, postoperative outcomes and survival were compared. RESULTS: In total, 162 patients underwent VL (n = 81) or VS (n = 81). Except for age [median (interquartile range) 68 (60-73) vs 71 (65-76) years; P = 0.034] and past medical history of cancer (32% vs 48%; P = 0.038), there was no difference between VL and VS in terms of demographics and comorbidities. Overall 30-day postoperative morbidity was similar in both groups (34% vs 30%; P = 0.5). The median time for chest tube removal [3 (1-5) vs 2 (1-3) days; P = 0.002] and median postoperative length of stay [6 (4-9) vs 5 (3-7) days; P = 0.039] were in favour of the VS group. Significantly larger tumour size (mean ± standard deviation 25.1 ± 3.1 vs 23.6 ± 3.1 mm; P = 0.001) and an increased number of lymph nodes removal [median (interquartile range) 14 (9-23) vs 10 (6-15); P < 0.001] were found in the VL group. During the follow-up [median (interquartile range) 31 (14-48) months], no statistical difference was found for local and distant recurrence in VL groups (12.3%) and VS group (6.1%) (P = 0.183). Overall survival (80% vs 80%) was comparable between both groups (P = 0.166). CONCLUSIONS: Despite a short follow-up, our preliminary data shows that local control is comparable for VL and VS.

CT-Derived Sarcopenia and Outcomes after Thoracoscopic Pulmonary Resection for Non-Small Cell Lung Cancer.

We aimed to evaluate whether computed tomography (CT)-derived preoperative sarcopenia measures were associated with postoperative outcomes and survival after video-assisted thoracoscopic (VATS) anatomical pulmonary resection in patients with early-stage non-small cell lung cancer (NSCLC). We retrospectively reviewed all consecutive patients that underwent VATS anatomical pulmonary resection for NSCLC between 2012 and 2019. Skeletal muscle mass was measured at L3 vertebral level on preoperative CT or PET/CT scans to identify sarcopenic patients according to established threshold values. We compared postoperative outcomes and survival of sarcopenic vs. non-sarcopenic patients. A total of 401 patients underwent VATS anatomical pulmonary resection for NSCLC. Sarcopenia was identified in 92 patients (23%). Sarcopenic patients were predominantly males (75% vs. 25%; p < 0.001) and had a lower BMI (21.4 vs. 26.5 kg/m2; p < 0.001). The overall postoperative complication rate was significantly higher (53.2% vs. 39.2%; p = 0.017) in sarcopenic patients and the length of hospital stay was prolonged (8 vs. 6 days; p = 0.032). Two factors were associated with postoperative morbidity in multivariate analysis: BMI and American Society of Anesthesiologists score >2. Median overall survival was comparable between groups (41 vs. 46 months; p = 0.240). CT-derived sarcopenia appeared to have a small impact on early postoperative clinical outcomes, but no effect on overall survival after VATS anatomical lung resection for NSCLC.

Is faster better? Impact of operative time on postoperative outcomes after VATS anatomical pulmonary resection.

Background: Video-assisted thoracic surgery (VATS) is now the preferred approach for standard anatomical pulmonary resections. This study evaluates the impact of operative time (OT) on post-operative outcomes after VATS anatomical pulmonary resection for non-small cell lung cancer (NSCLC). Methods: We retrospectively reviewed all consecutive patients undergoing VATS lobectomy or segmentectomy for NSCLC between November 2010 and December 2019. Postoperative outcomes were compared between short (<150 minutes) and long (≥150 minutes) OT groups. A multivariable analysis was performed to identify predictors of long OT and overall post-operative complications. Results: A total of 670 patients underwent lobectomy (n=496, 74%) or segmentectomy (n=174, 26%) for NSCLC. Mediastinal lymph node dissection was performed in 621 patients (92.7%). The median OT was 141 minutes (SD: 47 minutes) and 387 patients (57.8%) were operated within 150 minutes. Neoadjuvant chemotherapy was given in 25 patients (3.7%). Conversion thoracotomy was realized in 40 patients (6%). Shorter OT was significantly associated with decreased post-operative overall complication rate (30% vs. 41%; P=0.003), shorter median length of drainage (3 vs. 4 days; P<0.001) and shorter median length of hospital stay (6 vs. 7 days; P<0.001). On multivariable analysis, long OT (≥150 minutes) (OR 1.64, P=0.006), ASA score >2 (OR 1.87, P=0.001), FEV1 <80% (OR 1.47, P=0.046) and DLCO <80% (OR 1.5, P=0.045) were significantly associated with postoperative complications. Two predictors of long OT were identified: neoadjuvant chemotherapy (OR 3.11, P=0.01) and lobectomy (OR 1.5, P=0.032). Conclusions: A prolonged OT is significantly associated with postoperative complications in our collective of patients undergoing VATS anatomical pulmonary resection.

The size and sternal involvement of chest wall resections for malignant disease predict postoperative morbidity.

Background: Chest wall resections/reconstructions are a validated approach to manage tumors invading the thorax. However, how resection characteristics affect postoperative morbidity and mortality is unknown. We determined the impact of chest wall resection size and location on patient short and long-term postoperative outcomes. Methods: We reviewed all consecutive patients who underwent resections/reconstructions for chest wall tumors between 2003 and 2018. The impact of chest wall resection size and location and reconstruction on perioperative morbidity/mortality and oncological outcome were evaluated for each patient. Results: Ninety-three chest wall resections were performed in 88 patients for primary (sarcoma, breast cancer, n=66, 71%) and metastatic (n=27, 29%) chest wall tumors. The mean chest bony resection size was 107 (range, 15-375) cm2 and involved ribs only in 57% (n=53) or ribs combined to sternal/clavicular resections in 43% of patients (n=40). Chest defect reconstruction methods included muscle flaps alone (14%) prosthetic material alone (25%) or a combination of both (61%). Early systemic postoperative complications included pneumonia (n=15, 16%), atelectasis (n=6, 6%), pleural effusion (n=15, 16%) and arrhythmia (n=6, 6%). The most frequent long-term reconstructive complications included wound dehiscence (n=4), mesh infection (n=5) and seroma (n=4). Uni- and multivariable analyses indicated that chest wall resection size (>114 cm2) and location (sternum) were significantly associated with the occurrence of pneumonia and atelectasis [odds ratio (OR) =3.67, P=0.05; OR =78.92, P=0.02, respectively]. Disease-free and overall survival were 37±43 and 48±42 months for primary malignancy and of 24±33 and 48±53 months for metastatic chest wall tumors respectively with a mean follow-up of 46±44 months. Conclusions: Chest wall resections present good long-term oncological outcomes. A resection size above 114 cm2 and the involvement of the sternum are significantly associated with higher rates of postoperative pneumonia/atelectasis. This subgroup of patients should have reinforced perioperative physical therapy protocols.

Extended resection for potentially operable patients with stage III non-small cell lung cancer after induction treatment.

OBJECTIVE: Surgical treatment of locally advanced non-small cell lung cancer including single or multilevel N2 remains a matter of debate. Several trials demonstrate that selected patients benefit from surgery if R0 resection is achieved. We aimed to assess resectability and outcome of patients with locally advanced clinical T3/T4 (American Joint Committee on Cancer 8th edition) tumors after induction treatment followed by surgery in a pooled analysis of 3 prospective multicenter trials. METHODS: A total of 197 patients with T3/T4 non-small cell lung cancer of 368 patients with stage III non-small cell lung cancer enrolled in the Swiss Group for Clinical Cancer Research 16/96, 16/00, 16/01 trials were treated with induction chemotherapy or chemoradiation therapy followed by surgery, including extended resections. Univariable and multivariable analyses were applied for analysis of outcome parameters. RESULTS: Patients' median age was 60 years, and 67% were male. A total of 38 of 197 patients were not resected for technical (81%) or medical (19%) reasons. A total of 159 resections including 36 extended resections were performed with an 80% R0 and 13.2% pathological complete response rate. The 30- and 90-day mortality were 3% and 7%, respectively, without a difference for extended resections. Morbidity was 32% with the majority (70%) of minor grading complications. The 3-, 5-, and 10-year overall survivals for extended resections were 61% (95% confidence interval, 43-75), 44% (95% confidence interval, 27-59), and 29.5% (95% confidence interval, 13-48), respectively. R0 resection was associated with improved overall survival (hazard ratio, 0.41; P < .001), but pretreatment N2 extension (177/197) showed no impact on overall survival. CONCLUSIONS: Surgery after induction treatment for advanced T3/T4 stage including single and multiple pretreatment N2 disease resulted in 80% R0 resection rate and 7% 90-day mortality. Favorable overall survival for extended and not extended resection was demonstrated to be independent of pretreatment N status.

Performance of prolonged air leak scoring systems in patients undergoing video-assisted thoracoscopic surgery segmentectomy.

OBJECTIVES: We assessed the accuracy of 3 validated lobectomy scoring systems to predict prolonged air leak (PAL) in patients undergoing video-assisted thoracoscopic surgery (VATS) segmentectomy. METHODS: We reviewed all consecutive patients who had a VATS segmentectomy between January 2016 and October 2020. We determined PALs on postoperative day 5. These findings were correlated with the calculated Brunelli (gender, age, body mass index [BMI], forced expiratory volume in 1 s < 80 and pleural adhesion), Epithor (gender, location, dyspnoea score, BMI, type of resection and pleural adhesion) and European Society of Thoracic Surgeons (ESTS) (gender, BMI and forced expiratory volume in 1 s) scores of each patient. RESULTS: A total of 453 patients (mean age: 66.5 years, female/male sex ratio: 226/227) underwent a VATS segmentectomy for malignant (n = 400) and non-malignant (n = 53) disease. Postoperative cardiopulmonary complications and in-hospital mortality rates were 19.6% and 0.4%, respectively. Median chest tube drainage duration and hospital stay were 2 (interquartile range: 1-4) and 4 (interquartile range: 3-7) days, respectively. On day 5, the prevalence of PAL was 14.1%. The ESTS, Brunelli and Epithor scores for the treated population were, respectively, class A (6.8%), class B (3.2%), class C (10.8%) and class D (28.2%); very low and low (0%), moderate (5%), high (6.3%) and very high (21%); and class A (7%), class B (13.2%), class C (24%) and class D (27.8%). All scores correlated with PAL (p ≤ 0.001). The areas under the receiver operating characteristic (ROC) curve were 0.686, 0.680 and 0.644, respectively. CONCLUSIONS: All 3 scoring systems were correlated with PAL > 5 days following the VATS segmentectomies. ESTS scores seem easier to introduce in clinical practice, but validation by a multicentre cohort is mandatory.

Survival prognostic and recurrence risk factors after single pulmonary metastasectomy.

BACKGROUND: Identification of the prognostic factors of recurrence and survival after single pulmonary metastasectomy (PM). METHODS: Retrospective analysis of all consecutive patients who underwent PM for a single lung metastasis between 2003 and 2018. RESULTS: A total of 162 patients with a median age of 64 years underwent single PM. Video-Assisted Thoracic Surgery (VATS) was performed in 83.9% of cases. Surgical resection was achieved by wedge in 73.5%, segmentectomy in 7.4%, lobectomy in 17.9% and pneumonectomy in 1.2% of cases. The median durations of hospital stay and of drainage were 4 days (IQR 3-7) and 1 day (IQR 1-2), respectively. During the follow-up (median 31 months; IQR 15-58), 93 patients (57.4%) presented recurrences and repeated PM could be realized in 35 patients (21.6%) achieved by VATS in 77.1%. Non-colorectal tumour (HR 1.84), age < 70 years (HR 1.77) and previous extra-thoracic metastases (HR 1.61) were identified as prognostic factors of recurrence. Overall survival at 5-year was estimated at 67%. Non-colorectal tumour (HR 2.40) and mediastinal lymph nodes involvement (HR 3.42) were significantly associated with an increased risk of death. CONCLUSIONS: Despite high recurrence rates after PM, surgical resection shows low morbidity rate and acceptable long-term survival, thus should remain the standard treatment for single pulmonary metastases. TRIAL REGISTRATION: The Local Ethics Committee approved the study (No. 2019-02,474) and individual consent was waived.

Is sleeve lobectomy safe after induction therapy?-a systematic review and meta-analysis.

BACKGROUND: Sleeve lobectomy (SL) is a lung-sparing procedure, which is accepted as a valid operation for centrally-located advanced tumors. These tumors often require induction treatment by chemotherapy and/or radiotherapy to downstage the disease and thus facilitate subsequent surgery. However, induction therapy may potentially increase the risk of bronchial anastomotic complications and related morbidity. This meta-analysis aims to determine the impact of induction therapy on the outcomes of pulmonary SL. METHODS: We compared studies of patients undergoing SL or bilobectomy for non-small cell lung cancer (NSCLC) with and without induction therapy. Outcomes of interest were in-hospital mortality, morbidity, anastomosis complication and 5-year survival. Odds ratio (OR) were computed following the Mantel-Haenszel method. RESULTS: Ten studies were included for a total of 1,204 patients. There was no statistical difference for between patients who underwent induction therapy followed by surgery and patients who underwent surgery alone in term of post-operative mortality (OR: 1.80, 95% confidence interval (CI): 0.76-4.25, P value =0.19) and morbidity (OR: 1.17, 95% CI: 0.90-1.52, P value =0.237). Anastomosis related complications rate were 5.2% and appears increased after induction therapy with a statistical difference close to the significance (OR: 1.65, 95% CI: 0.97-2.83, P value =0.06). Patients undergoing surgery alone showed better survival at 5 years (OR: 1.52, 95% CI: 1.15-2.00, P value =0.003). CONCLUSIONS: SL following induction therapy can be safely performed with no increase of mortality and morbidity. However, the need for induction therapy before surgery is associated with increased anastomotic complications and poorer survival prognosis at 5 years.

Early discharge after thoracoscopic anatomical pulmonary resection for non-small-cell lung cancer.

OBJECTIVES: Although video-assisted thoracic surgery (VATS) has shortened hospitalization duration for non-small-cell lung cancer (NSCLC) patients, the factors associated with early discharge remain unclear. This study aimed to identify patients eligible for a 72-h stay after VATS anatomical resection. METHODS: Monocentric retrospective study including all consecutive patients undergoing VATS anatomical resection for NSCLC between February 2010 and December 2019. Two groups were defined according to the discharge: 'early discharge' (within 72 postoperative hours) and 'routine discharge' (at >72 postoperative hours). RESULTS: A total of 660 patients with a median age of 66.5 years (interquartile range 60-73 years) (female/male: 321/339) underwent VATS anatomical pulmonary resection for NSCLC [segmentectomy in 169 (25.6%), lobectomy in 481 (72.9%), bilobectomy in 8 (1.2%) and pneumonectomy in 2 (0.3%) patients]. The cardiopulmonary and Clavien-Dindo III-IV postoperative complication rates were 32.6% and 7.7%, respectively. The median postoperative length of stay was 6 days (interquartile range 4-10 days). In total, 119 patients (18%) could be discharged within 72 h of surgery. On multivariable analysis, the factors significantly associated with an increased likelihood of early discharge were: body mass index >20 kg/m2 [odds ratio (OR) 2.37], absence of prior cardiopathy (OR 2), diffusing capacity of the lung for carbon monoxide >60% (OR 1.82), inclusion in an enhanced recovery after surgery protocol (OR 2.23), use of a single chest tube (OR 5.73) and postoperative transfer to the ward (OR 4.84). Factors significantly associated with a decreased likelihood of early discharge were: age >60 years (OR 0.53), American Society of Anaesthesiologists score >2 (OR 0.46) and use of an epidural catheter (OR 0.41). Readmission rates were not statistically different between both groups (5.9% vs 3.1%; P = 0.17). CONCLUSIONS: Age, pulmonary functions and comorbidities may influence discharge after VATS anatomical resection. The early discharge does not increase readmission rates.

Invasive Hormographiella aspergillata infection in patients with acute myeloid leukemia: Report of two cases successfully treated and review of the literature.

Hormographiella aspergillata is a rare cause of invasive mold infection, mostly described in patients with hematological malignancies. We describe two cases of invasive H. aspergillata infections in patients with acute myeloid leukemia, successfully managed with complete surgical resection of the lesions and antifungal therapy of voriconazole alone or liposomal amphotericin B, followed by voriconazole, highlighting the key role of a multidisciplinary approach for the treatment of this rare and severe invasive mold infection.

GLUT1 Expression in Tumor-Associated Neutrophils Promotes Lung Cancer Growth and Resistance to Radiotherapy.

Neutrophils are the most abundant circulating leucocytes and are essential for innate immunity. In cancer, pro- or antitumor properties have been attributed to tumor-associated neutrophils (TAN). Here, focusing on TAN accumulation within lung tumors, we identify GLUT1 as an essential glucose transporter for their tumor supportive behavior. Compared with normal neutrophils, GLUT1 and glucose metabolism increased in TANs from a mouse model of lung adenocarcinoma. To elucidate the impact of glucose uptake on TANs, we used a strategy with two recombinases, dissociating tumor initiation from neutrophil-specific Glut1 deletion. Loss of GLUT1 accelerated neutrophil turnover in tumors and reduced a subset of TANs expressing SiglecF. In the absence of GLUT1 expression by TANs, tumor growth was diminished and the efficacy of radiotherapy was augmented. Our results demonstrate the importance of GLUT1 in TANs, which may affect their pro- versus antitumor behavior. These results also suggest targeting metabolic vulnerabilities to favor antitumor neutrophils. SIGNIFICANCE: Lung tumor support and radiotherapy resistance depend on GLUT1-mediated glucose uptake in tumor-associated neutrophils, indicating that metabolic vulnerabilities should be considered to target both tumor cells as well as innate immune cells.

Impact of an enhanced recovery after surgery pathway on thoracoscopic lobectomy outcomes in non-small cell lung cancer patients: a propensity score-matched study.

BACKGROUND: This study evaluates the effect of enhanced recovery after surgery (ERAS) pathways on postoperative outcomes of non-small cell lung cancer (NSCLC) patients undergoing video-assisted thoracic surgery (VATS) lobectomy. METHODS: We retrospectively reviewed all consecutive patients undergoing VATS lobectomy for NSCLC between January 2014 and October 2019 and assigned them to the relevant group ("pre-ERAS" or "ERAS"). Length of stay, readmissions and complications within 30 days were compared between both groups. A propensity score-matched analysis was performed based on sex, age, type of operation, comorbidities, American Society of Anesthesiologists (ASA) score and preoperative pulmonary functions. RESULTS: A total of 307 records (164 male/143 female; 140 ERAS/167 pre-ERAS; median age: 67) were reviewed. There was no statistical difference in patient's characteristics. Overall ERAS compliance was 81%. The ERAS group presented significantly shorter length of stay (median 5 vs. 7 days; P=0.004) without significant difference in cardiopulmonary complication rate (27.1% vs. 35.9%; P=0.1). Readmission (3.6% vs. 5.4%; P=0.75) and duration of drainage (median 2 vs. 3 days; P=0.14) were similar between groups. The propensity score-matched analysis showed that the length of hospital stay was reduced by 1.4 days (P=0.034) and the postoperative cardiopulmonary complication rate by 13% (P=0.044) in the ERAS group. CONCLUSIONS: Adoption of an ERAS pathway for VATS lobectomies in NSCLC patients has decreased the length of hospital stay and the cardiopulmonary complication rate without affecting the readmission rate.

Short-term local control after VATS segmentectomy and lobectomy for solid NSCLC of less than 2 cm.

INTRODUCTION: VATS pulmonary segmentectomy is increasingly proposed as a parenchyma-sparing resection for tumors smaller than 2 cm in diameter. The aim of this study was to compare short-term oncological results and local control in solid non-small cell lung cancers (NSCLCs) <2 cm surgically treated by intentional VATS segmentectomy or lobectomy. METHODS: This study was a single center retrospective study of consecutive patients undergoing VATS lobectomy (VL) or segmentectomy (VS) for solid <2 cm NSCLC from January 2014 to October 2019. Results In total, 188 patients with a median age of 65 years (male/female: 99/89) underwent VS (n = 96) or VL (n = 92). Segmentectomies in the upper lobes were performed in 57% and as a single segment in 55% of cases. There was no statistically significant difference between VS and VL in terms of demographics, comorbidities, postoperative outcomes, dissected lymph node stations (2.89 ± 0.95 vs. 2.93 ± 1, P = 0.58), rate of pN1 (2.2% vs. 2.1%, P = 0.96) or pN2 upstaging (1.09% vs. 1.06%, P = 0.98). Adjuvant chemotherapy was given in 15% of patients in the VL and 11% in the VS group. During follow-up (median: 23 months), no patients presented with local nodal recurrence or on the stapler line (VS group). Three patients on VL and two in VS groups presented with recurrence on the remnant operated lung. New primary pulmonary tumors were diagnosed in 3.3% and 6.3% of patients in the VL and VS groups, respectively. CONCLUSIONS: Despite the short follow-up, our preliminary data shows that local control is comparable for VATS lobectomy and VATS segmentectomy for patients with NSCLC <2 cm.

Is repeated pulmonary metastasectomy justified?

Recurrence after pulmonary metastasectomy (PM) is frequent, but it is unclear to whom repeated pulmonary metastasectomy (RPM) offers highest benefits. Retrospective analysis of oncological and post-operative outcomes of consecutive patients who underwent PM from 2003 to 2018. Overall survival (OS) and disease-free interval (DFI) were calculated. Cox regression was used to identify variables influencing OS and DFI. In total, 264 patients (female/male: 114/150; median age: 62 years) underwent PM for colorectal cancer (32%), sarcoma (19%), melanoma (16%) and other primary tumors (33%). Pulmonary metastasectomy was approached by video-assisted thoracic surgery (VATS) in 73% and pulmonary resection was realized by non-anatomical resection in 76% of cases. The overall median follow-up time was 33 months (IQR 16-56 months) and overall 5-year survival rate was 62%. Local or distant recurrences were observed in 172 patients (65%) and RPM could be performed in 66 patients (25%) for a total of 116 procedures. RPM was realized by VATS in 49% and pulmonary resection by wedge in 77% of cases. In RPM patients, the 5-year survival rate after first PM was 79%. Post-operative cardio-pulmonary complication rate (13% vs. 12%; p = 0.8) and median length of stay (4 vs. 5 days; p = 0.2) were not statistically different between first PM and RPM. Colorectal cancer (HR 0.56), metachronous metastasis (HR 0.48) and RPM (HR 0.5) were associated with better survival. In conclusion, our results suggest that RPM offers favorable survival rates without increasing post-operative morbidity.

Impact of Compliance With Components of an ERAS Pathway on the Outcomes of Anatomic VATS Pulmonary Resections.

OBJECTIVES: Implementation of an Enhanced Recovery After Surgery (ERAS) program is associated with better postoperative outcomes. The aim of this study was to evaluate the impact of ERAS compliance (overall and to specific elements of the program) on them. DESIGN: Retrospective analysis of prospectively collected data. SETTING: University hospital, monocentric. PARTICIPANTS: All adult (≥18 years old) patients undergoing video-assisted thoracic surgery (VATS) anatomic pulmonary resection. INTERVENTIONS: ERAS-governed VATS anatomic pulmonary resection. MEASUREMENTS AND MAIN RESULTS: Demographics, surgical characteristics and pre-, peri-, and postoperative compliance with 16 elements of the ERAS program were assessed. Postoperative outcomes and length of stay were compared between low- (<75% of adherence) and high-compliance (≥75%) groups. From April 2017 to November 2018, 192 ERAS patients (female/male: 98/94) of median age of 66 years (interquartile range 58-71) underwent VATS resection (109 lobectomies, 83 segmentectomies). There was no 30-day mortality and resurgery rate was 5.7%. Overall ERAS compliance was 76%. High compliance was associated with fewer complications (18% v 48%, p < 0.0001) and lower rate of delayed discharge (37% v 60%, p = 0.0013). Early removal of chest tubes (odds ratio [OR]: 0.26, p < 0.002), use of electronic drainage (OR: 0.39, p = 0.036), opioid cessation on day 3 (OR: 0.28, p = 0.016), and early feeding (OR: 0.12, p = 0.014) were associated with reduced rates of postoperative complications. Shorter hospital stay was correlated with early removal of chest tubes (OR: 0.12, p < 0.0001) and opioid cessation on day 3 (OR: 0.23, p = 0.001). CONCLUSIONS: High ERAS compliance is associated with better postoperative outcomes in patients undergoing anatomic pulmonary VATS resections.

Prognostic factors of oligometastatic non-small-cell lung cancer following radical therapy: a multicentre analysis.

OBJECTIVES: Patients with oligometastatic non-small-cell lung cancer (NSCLC) may benefit from therapy with curative intent. Our goal was to identify prognostic factors related to better prognosis in a multicentre analysis of patients who underwent surgery of primary tumours in combination with radical treatment of all metastatic sites. METHODS: We retrospectively reviewed the records of oligometastatic patients who underwent resection of primary tumours at 4 centres (August 2001-February 2018). Oligometastasis was defined as ≤5 synchronous metastases in ≤2 organs. Radical metastatic treatment was surgery, radiotherapy or a combination. The Cox proportional hazards model was used for identification of prognostic factors on overall survival. RESULTS: We treated 124 patients; 72 (58%) were men, mean age 60 ± 9.8 years, with 87 (70%) adenocarcinoma. Sixty-seven (54%) patients had positive pathologic-N stage (pN). Brain metastases were most common (n = 76; 61%) followed by adrenal (n = 13; 10%) and bone (n = 12; 10%). Systemic therapy was administered in 101 (82%) patients. Median follow-up was 60 months [95% confidence interval (CI) 41-86]. Thirty- and 90-day mortality rates were 0 and 2.4%, respectively. One-, 2-, and 5-year overall survival were 80%, 58% and 36%, respectively. Cox regression analysis showed that patients ≤60 years [hazard ratio (HR) 0.41, 95% CI 0.24, 0.69; P = 0.001] and patients with pN0 (HR 0.38, 95% CI 0.21-0.69; P = 0.002) had a significant survival benefit. The presence of bone metastases negatively affected survival (HR 2.53, 95% CI 1.05-6.09; P = 0.04). CONCLUSIONS: Treatment with curative intent of selected oligometastatic NSCLC, including resection of the primary tumour, can be performed safely and with excellent 5-year survival rates, especially in younger patients with pN0 disease.

Impact of complex segmentectomies by video-assisted thoracic surgery on peri-operative outcomes.

BACKGROUND: Pulmonary segmentectomies are generally classified into simple (tri-segmentectomy or lingulectomy as well as apical or basilar segmentectomy) and complex (individual or bi-segmentectomy of the upper, middle and lower lobes). Complex segmentectomies are technically feasible by video-assisted thoracic surgery (VATS) but remain challenging, and reports on post-operative outcomes are scarce. This study analyzes the differences between simple and complex VATS segmentectomy in terms of peri- and post-operative outcomes. METHODS: We retrospectively reviewed records of all patients who underwent anatomical pulmonary segmentectomy by VATS from 2014 to 2018 in two university hospitals. RESULTS: A total of 232 patients (114 men; median age 67 years; range, 29-87 years) underwent VATS segmentectomy for primary lung cancer (n=177), metastases (n=26) and benign lesions (n=29). The overall 30-day mortality and morbidity rates were 0.8% and 29.7%, respectively. The re-operation rate was 4.7%. Complex segmentectomy was realized in 111 patients including 86 (77.5%) upper lobe segmentectomies and 44 (39.6%) bi-segmentectomies. There was no statistical difference between complex and simple segmentectomy in terms of operative time (145 vs. 143 min, respectively; P=0.79) and chest tube duration [median: 1 (range, 0-33) vs. 2 (range, 1-19) days, respectively; P=0.95]. Post-operative overall complication rates were similar for both groups (30% vs. 30%, respectively; P=0.99) and were not correlated with the type of segmentectomy. However, complex segmentectomy patients had a shorter length of hospitalization compared to simple segmentectomy patients [median: 5 (range, 1-36) vs. 7 (range, 2-31) days; P=0.026]. Interestingly, complex segmentectomies were realized most frequently 2 years after implementation of VATS segmentectomy (23% vs. 77%; P=0.01). CONCLUSIONS: In comparison with simple segmentectomy, complex segmentectomy by VATS seems to present similar post-operative complication rates. Learning curve and progressive increase in acceptance by surgeons seem to be key elements for successful implementation of complex segmentectomies and could explain the shorter length of stay we observed.
