RESUMEN
Many changes have occurred in the field of thoracic surgery over the last several years. In this review, we will discuss new diagnostic techniques for lung cancer, innovations in surgery, and major updates on latest treatment options including immunotherapy. All these have significantly started to change our approach toward the management of lung cancer and have great potential to improve the lives of our patients afflicted with this disease.

OBJECTIVE: Segmentectomy is becoming the standard of care for small, peripheral non-small cell lung cancer. To improve perioperative management in this population, this study aims to identify factors influencing hospital length of stay after segmentectomy. METHODS: Patients who underwent segmentectomy for any indication between January 2018 and May 2023 were identified using a prospectively maintained institutional database. Multivariable logistic regression models were used to estimate associations between clinical features and prolonged (≥3 days) hospital stay. A nomogram was designed to understand better and possibly calculate the individual risk of prolonged hospital stays. RESULTS: In total, 533 cases were included; 337 (63%) were female. Median age was 66 years (interquartile range [IQR], 63-75). The median size of resected lesions was 1.6 cm (IQR, 1.3-2.1 cm). Median hospital stay was 3 days (IQR, 2-4 days). Major adverse events occurred in 31 (5.8%) cases. The 30-day readmission rate was 5.8% (n = 31). There was no 30-day mortality; 90-day mortality was <1%. Patients older than 75 years (odds ratio [OR], 2.01, 95% confidence interval [CI], 1.15-3.57, P = .02), those with forced expiratory volume in 1 second <88% predicted (OR, 1.99; 95% CI, 1.38-2.89, P < .001), or positive smoking history (OR, 1.72; 95% CI, 1.15-2.60, P = .01) were more likely to have prolonged hospital stays after segmentectomy. A nomogram accounting for age, sex, forced expiratory volume in 1 second, body mass index, smoking history, and comorbidities was created to predict the probability of prolonged hospital stay with an area under the receiver operating characteristic curve of 0.66. CONCLUSIONS: Older patients, those with reduced pulmonary function, and current and past smokers have elevated risk for prolonged hospital stays after segmentectomy. Validation of our nomogram could improve perioperative risk stratification in patients who undergo segmentectomy.
RESUMEN
Background: Uniportal video-assisted thoracoscopic surgery (VATS) segmentectomy is gaining worldwide acceptance, but experience in North America is still limited. We report a North American multicenter comparison of uniportal vs. multiportal VATS segmentectomy. Methods: We performed an institutional review board-exempt retrospective chart review on prospectively collected databases at two North American centers, from January 2012 to December 2020. We included all VATS segmentectomy patients and excluded emergent cases (n=1), patients with incomplete records (n=2), and segmentectomy performed in conjunction with another type of lung resection (n=1). We recorded patient demographics, perioperative data, 30-day postoperative complications and compared outcomes between cohorts. We provided descriptive statistics for each group. We calculated propensity score matching and paired patients 1:1. We defined P values less than 0.05 as statistically significant. Results: We performed a total of 423 VATS segmentectomies, 181 uniportal (42.7%) vs. 242 multiportal (57.2%). Indications for surgery were primary lung cancer (n=339), metastatic (n=41), benign disease (n=40), and other (n=3). We staged 85.1% of patients preoperatively with positron emission tomography-computed tomography (PET-CT) scan according to National Comprehensive Cancer Network (NCCN) guidelines. Propensity score matching generated 156 patients on each group. Operating time was significantly lower in the uniportal group compared to multiportal (130 vs. 161 min respectively, P<0.001). We found no difference in estimated blood loss, Clavien-Dindo class III-IV complications, conversion to thoracotomy, R0 resection rate, nodal upstaging, hospital length of stay, 30-day readmission or mortality. Conclusions: Our experience from two North American centers indicates that, in experienced hands, postoperative outcomes after uniportal and multiportal VATS segmentectomy are comparable.
RESUMEN
In the eighth edition TNM staging, the T3N0M0 category represents a heterogeneous group of non-small cell lung cancers (NSCLC). This study aims to compare the oncologic outcomes associated with individual T3 features. We performed a single-institution, retrospective analysis of 280 consecutive patients with pT3N0M0 NSCLC. Multivariate regression models were used to estimate associations of clinical factors with oncologic outcomes. The patients were grouped according to their T3 features into 4 prognostic groups: chest wall infiltration (CWI-PG), largest diameter >5 cm and ≤7 cm (Size-PG), presence of a satellite nodule (SN-PG), and all other T3 features. Overall survival (OS) and progression-free survival (PFS) were estimated using Kaplan-Meier and Cox proportional hazard analyses. Tumors were most often classified as T3N0M0 by size (156 patients, 55.7%), and the highest rate of incomplete resection occurred in patients with CWI (n = 7, 25.9%). In multivariate analysis, CWI (hazard ratio [HR] 2.45, 95% confidence interval [CI] 1.36, 4.44), incomplete resection (HR 3.01, 95% CI 1.29, 7.05), and age >65 (HR 1.6; 95% CI 1.08, 2.38) were independently associated with worse OS, and female sex was associated with better OS (HR 0.6, 95% CI 0.42, 0.87). The CWI-PG had poorer OS when compared with each of the other prognostic groups (P < 0.05), and the Size-PG had inferior OS when compared with the SN-PG (P = 0.039). This single-center study demonstrated significant differences in OS and PFS between patients with different T3 classifying features and suggest that further subdivision of the T3 category should be considered.

The optimal number of incisions for video-assisted thoracoscopic surgery (VATS) lobectomy, the standard treatment for early-stage nonsmall cell lung cancer (NSCLC), is still a matter of great debate. To compare single-incision (uniportal) VATS (U-VATS) with traditional multiportal VATS (M-VATS), we retrospectively reviewed the surgical outcomes of a large cohort of patients. Our prospectively maintained institutional database was queried retrospectively. All patients from 2014 to 2017 who underwent VATS lobectomy as the primary procedure for clinical stage I or II NSCLC were identified. A univariate comparison and a propensity-matched analysis incorporating preoperative variables were performed. The incidence of postoperative complications was compared. During the study period, 722 patients underwent VATS lobectomy for early-stage NSCLC, 62% by M-VATS, and 38% by U-VATS. In the univariate analysis, U-VATS performed by an experienced surgeon was associated with decreased intraoperative bleeding and shortened duration of surgery, duration of chest tube drainage, and length of hospital stay as compared with M-VATS (Pâ¯<â¯0.001). Mediastinal lymph node dissection and complete resection were accomplished similarly using U-VATS and M-VATS. When the 2 approaches were compared through propensity matching, U-VATS was associated with fewer pneumonias (Pâ¯=â¯0.012), as well as decreased intraoperative bleeding (Pâ¯<â¯0.001), faster surgery (Pâ¯<â¯0.001), shorter duration of chest tube drainage (Pâ¯=â¯0.001), and shorter hospital stay (Pâ¯<â¯0.001). At our institution, in the hands of an experienced surgeon, U-VATS lobectomy is safe, feasible, and can result in similar short-term outcomes for early-stage NSCLC as compared with M-VATS.
