ABSTRACT
OBJECTIVE: Esophageal cancers that invade the submucosa (T1b) have increased risk for occult lymph node metastases. To avoid the morbidity and recovery from esophagectomy, patients with cT1bN0 tumors have been increasingly managed endoscopically. We hypothesized that tumor attributes could predict upstaging and outcome associated with surgical and endoscopic treatment. Our objective was to evaluate the comparative effectiveness of esophagectomy across different cT1bN0 tumor attributes. METHODS: Treatment-naïve patients who underwent endoscopic management or esophagectomy for a clinical stage cT1bN0 esophageal cancer diagnosed between 2010 and 2018 in the National Cancer Database were identified. Factors associated with upstaging were assessed by logistic regression. Adjusted survival was assessed by Kaplan-Meier analysis of 528 propensity-matched pairs and accelerated time failure models, stratified across tumor attributes. RESULTS: Overall, 1469 patients classified as cT1bN0 were identified; 926 underwent esophagectomy and 543 were managed endoscopically. In general, patients who were managed endoscopically were older (median, 71; interquartile range, 63-78; vs 66; interquartile range, 60-72; P < .0001) with smaller tumors compared with the patients who were managed with esophagectomy. Nodal upstaging was associated with lymphovascular invasion (odds ratio [OR], 6.88; confidence interval [CI], 4.39-10.77; P < .0001), poor tumor differentiation (OR, 2.77; CI, 1.30-5.88; P = .0081), and tumor size >1 cm (OR, 3.19; CI, 1.49-6.83, P = .0028). Overall survival was better among propensity-matched patients who underwent esophagectomy (5-year 68.4% vs 59.7% endoscopic, P < .001). However, accelerated time failure models suggested similar outcomes among patients with well-differentiated tumors managed surgically or endoscopically. CONCLUSIONS: Esophagectomy was associated with improved survival for cT1bN0 esophageal cancer; however, endoscopic treatment may achieve similar survival in patients with favorable tumor attributes. Further study is warranted.
ABSTRACT
BACKGROUND: Palliative treatment has been associated with improved quality of life and survival for a wide variety of metastatic cancers. However, it is unclear whether the benefits of palliative treatment are uniformly experienced across the US cancer population. We evaluated patterns and outcomes of palliative treatment based on socioeconomic, sociodemographic and treating facility characteristics. METHODS: Patients diagnosed between 2008 and 2019 with Stage IV primary cancer of nine organ sites were analyzed in the National Cancer Database. The association between identified variables, and outcomes concerning the administration of palliative treatment were analyzed with multivariable logistic regression and Cox proportional hazard models. RESULTS: Overall 238,995 (23.6%) of Stage IV patients received palliative treatment, which increased over time for all cancers (from 20.7% in 2008 to 25.6% in 2019). Palliative treatment utilization differed significantly by region (West less than Northeast, OR: 0.55 [0.54-0.56], p < 0.001) and insurance payer status (uninsured greater than private insurance, OR: 1.35 [1.32-1.39], p < 0.001). Black race and Hispanic ethnicity were also associated with lower rates of palliative treatment compared to White and non-Hispanics respectively (OR for Blacks: 0.91 [0.90-0.93], p < 0.001 and OR for Hispanics: 0.79 [0.77-0.81] p < 0.001). CONCLUSIONS: There are important differences in the utilization of palliative treatment across different populations in the United States. A better understanding of variability in palliative treatment use and outcomes may identify opportunities to improve informed decision making and optimize quality of care at the end-of-life.

Background: Non-intubated thoracoscopic surgery with spontaneous breathing is rarely utilized, but may have several advantages over standard intubation, especially in those with significant cardiopulmonary comorbidities. In this study we evaluate the safety, feasibility, and 3-year survival of thoracoscopic surgery without endotracheal intubation for oncologic and non-oncologic indications. Methods: All consecutive patients [2018-2022] selected for lung resection or other pleural space intervention under local anesthesia and sedation were compared to a cohort undergoing elective thoracoscopic procedures with endotracheal intubation. A propensity-score matched cohort was used to compare perioperative outcomes and 3-year overall survival. Results: A total of 72 patients underwent thoracoscopic surgery without intubation compared to 1,741 who were intubated. Non-intubated procedures included 19 lobectomies (26.4%), 9 segmentectomies (12.5%), 25 wedge resections (34.7%), and 19 pleural or mediastinal resections (26.4%). Non-intubated patients had a lower average body mass index (BMI; 24.6 vs. 27.1 kg/m2, P<0.001) and a higher comorbidity burden. Primary lung cancer was the indication in 30 (41.7%) non-intubated patients. The non-intubated cohort had no operative or 30-day mortality. After propensity-score matching, there was no significant difference in pre-operative factors. In propensity-score matched analysis, non-intubated patients had shorter median total operating room time (109 vs. 159 min, P<0.001) and procedure time (69 vs. 119 min, P<0.001). Peri-operative morbidity was rare and did not differ between intubated and non-intubated patients. There was no significant difference in 3-year survival associated with non-intubation in the propensity-score matched cohorts (95% vs. 89%, P=0.10) or in a Cox proportional hazard model [hazard ratio (HR), 1.15; 95% confidence interval (CI): 0.36-3.67; P=0.81]. Conclusions: Non-intubated thoracoscopic surgery is safe and feasible in carefully selected patients for both benign and oncologic indications.
