Does morbid obesity influence perioperative outcomes after video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer? Analysis of the Italian VATS group registry
Objectives Obesity in Europe, and worldwide, has been an increasing epidemic during the past decades. Moreover, obesity has important implications regarding technical issues and the risks associated with surgical interventions. Nevertheless, there is a lack of evidence assessing the influence of obesity on video-assisted thoracic surgery (VATS) lobectomy results. Our study aimed to assess the impact of morbid obesity on perioperative clinical and oncological outcomes after VATS lobectomy using a prospectively maintained nationwide registry. Methods The Italian VATS lobectomy Registry was used to collect all consecutive cases from 55 Institutions. Explored outcome parameters were conversion to thoracotomy rates, complication rates, intra-operative blood loss, surgical time, hospital postoperative length of stay, chest tube duration, number of harvested lymph-node, and surgical margin positivity. Results From 2016 to 2019, a total of 4412 patients were collected. 74 patients present morbid obesity (1.7%). Multivariable-adjusted analysis showed that morbid obesity was associated with a higher rate of complications (32.8% vs 20.3%), but it was not associated with a higher rate of conversion, and surgical margin positivity rates. Moreover, morbid obesity patients benefit from an equivalent surgical time, lymph-node retrieval, intraoperative blood loss, hospital postoperative length of stay, and chest tube duration than non-morbid obese patients. The most frequent postoperative complications in morbidly obese patients were pulmonary-related (35%). Conclusion Our results showed that VATS lobectomy could be safely and satisfactorily conducted even in morbidly obese patients, without an increase in conversion rate, blood loss, surgical time, hospital postoperative length of stay, and chest tube duration. Moreover, short-term oncological outcomes were preserved
Chemoradiotherapy followed by surgery versus surgery alone in esophageal cancer patients: is it time for additional evidence?
Recent efforts to improve survival in patients with locally advanced esophageal carcinoma have combined both systemic and local therapy. However, the role of neoadjuvant chemoradiotherapy in technically operable IIa-III esophageal carcinoma is still unresolved
Posterior mediastinal melanoma causing severe dysphagia: A case report
<p>Abstract</p> <p>Introduction</p> <p>We describe an original case of progressive severe dysphagia caused by a posterior mediastinal metastatic melanoma of unknown origin. To the best of our knowledge, such an event has never been described before in the literature.</p> <p>Case presentation</p> <p>A progressive severe dysphagia case is reported induced by a melanoma of unknown origin (metastatic to a posterior mediastinal lymph node). At the time of diagnosis, the lesion appeared as a large posterior mediastinal mass mimicking a neurogenic tumour with oesophageal involvement. After complete resection, pathological assessment of the tumour by immunohistochemistry was consistent with nodal metastatic melanoma.</p> <p>Conclusion</p> <p>This report of a posterior mediastinal lymph node melanoma is unique. The nodal origin is definitely unusual: a primary melanoma should always be carefully ruled out. In fact no other evidence, a part from the absence of the tumour elsewhere, can support the diagnosis of a primary nodal melanoma.</p
High incidence of vascular complication after computed tomography guided lung biopsy : what's matter , the patient or the tecnique?
We read with interest the article of Anzidei on a predicitive score of complication after lung computed tomography -guided biopsy . We think there is a percentage of complications especially pneumotohorax which are impossible to avoid , but it would be useful to predict in which cases they occur with hiogh frequency
Is Post-Operative Lung Ultrasonography Effective in Lung Abnormalities Analysis?
We read with interest the article of Dr. Patella (1) about the use of chest ultrasonography after thoracic surgery for pneumothorax evaluation and management. We completely agree about the use of ultrasound in the post-operative evaluation with the possibility to reduce the number of chest X-ray (CXR). In fact, it is well known that in many cases the postoperative CXR, especially when daily performed, represents a possible waste of time and resources(2)
Surgeon experience does not influence nodal upstaging during vats lobectomy: Results from a large prospective national database
Background: Despite recent improvement in preoperative staging, nodal and mediastinal upstaging occur in about 5% to 15% of cN0 patients. Different clinical and tumor characteristics are associated with upstaging, whereas the role of the surgeon's experience is not well evaluated. This study aimed to investigate if operator experience might influence nodal upstaging during video-assisted thoracic surgery anatomical lung resection. Methods: Clinical and pathological data from the prospective video-assisted thoracic surgery Italian nationwide registry were reviewed and analyzed. Patients with incomplete data about tumor and surgical characteristics, ground glass opacities tumors, cN2 to 3, and M+ were excluded. Clinical data, tumor characteristics, and surgeon experience were correlated to nodal and mediastinal (N2) upstaging using Pearson's χ2 statistic or Fisher exact test for categorical variables and Mann-Whitney U and t tests for quantitative variables. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of video-assisted thoracic surgery major anatomical resections and years after residency. Results: Final analysis was conducted on 3,319 cN0 patients for nodal upstaging and 3,471 cN0N1 patients for N2 upstaging. Clinical tumor-nodes-metastasis stage was stage I in 2,846 (81.9%) patients, stage II in 533 (15.3%), and stage III (cT3N1) in 92 (2.8%). Nodal upstaging occurred in 489 (13.1%) patients, whereas N2 upstaging occurred in 229 (6.1%) patients. Years after residency (P = .60 for nodal, P = .13 for N2 upstaging) and a number of video-assisted thoracic surgery procedures(P = .49 for nodal, P = .72 for nodal upstaging) did not correlate with upstaging. Multivariable analysis confirmed cT-dimension (P = .001), solid nodules (P < .001), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P < .001) as factors independently correlated to nodal upstaging, whereas cT-dimension (P = .005), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P = .028) resulted independently correlated to N2 upstaging. Conclusion: Our study showed that surgeon experience did not influence nodal and mediastinal upstaging during -assisted thoracic surgery anatomical resection, whereas cT-dimension, clinical tumor-nodes-metastasis, and maximum standardized uptake values resulted independently correlated to nodal and mediastinal upstaging
Surgical Effectiveness of Uniportal-VATS Lobectomy Compared to Open Surgery in Early-Stage Lung Cancer
BackgroundAlthough the feasibility and safety of Uniportal-Video-Assisted thoracic surgery (U-VATS) has been proven, its surgical effectiveness is still debated. The aim of this study is to assess the equivalence of the U-VATS approach compared with an open technique in terms of surgical (nodal-upstaging, complications, and post-operative results) and short-term survival outcomes. MethodsThe clinical data of patients undergoing lobectomy for NSCLC at our center, from January 2014 to December 2019, were analyzed retrospectively. All patients undergoing open or U-VATS lobectomy with lymphadenectomy for early-stage lung cancer (cT1-T3N0, stages IA-IIB) were included in the study. Only 230 patients satisfied the inclusion criteria. Group bias was reduced through 1:1 propensity score matching, which resulted in 46 patients in each group (open surgery and U-VATS). ResultsThe intra- and post-operative mortality were null in both groups. There was no difference in the post-operative complications (p: 1.00) between U-VATS and open lobectomy. There was also no recorded difference in the pathological nodal up-staging [11 (23.9%) after thoracotomy vs. 8 (17.4%) after U-VATS, p: 0.440). The chest tube duration was longer in the open group (p: 0.025), with a higher post-operative pain (p: 0.001). Additionally, the 3-year overall survival (OS) was 78% after U-VATS lobectomy vs. 74% after open lobectomy (p: 0.204), while 3-year disease-specific survival (DSS) was 97 vs. 89% (p: 0.371), respectively. The 3-year disease-free survival (DFS) was 62% in the U-VATS group and 66% in the thoracotomy group, respectively (p: 0.917). ConclusionsUniportal-VATS lobectomy for the treatment of early-stage lung cancer seems to be a safe and effective technique with similar surgical and short-term survival outcomes as open surgery, but with lower post-operative pain and shorter in-hospital stay
