Background: Evidence is limited characterizing sociodemographically diverse patient populations with lung cancer in relation to smoking status.Methods: In a cross-sectional analysis of adults diagnosed with lung cancer at ages ≥30 years from 2007-2018 within an integrated healthcare system, overall and sex-specific prevalence of never smoking were estimated according to sociodemographic and clinical characteristics. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were also estimated using modified Poisson regression to identify patient characteristics associated with never smoking, overall and by sex. Similar analyses were conducted to explore whether prevalence and association patterns differed between non-Hispanic White and Asian/Pacific Islander patients.
Background A few observational studies have found that outcomes after esophagectomies by thoracic surgeons are better than those by general surgeons. Methods Non-emergent esophagectomy cases were identified in the 2016-2017 American College of Surgeons NSQIP database. Associations between patient characteristics and outcomes by thoracic versus general surgeons were evaluated with univariate and multivariate logistic regression. Results Of 1,606 cases, 886 (55.2%) were performed by thoracic surgeons. Those patients differed from patients treated by general surgeons in race (other/unknown 19.3% vs 7.8%; P<.001) but not in other baseline characteristics (age, sex, BMI, and comorbidities). Thoracic surgeons performed an open approach more frequently (48.9% vs 30.8%, P<.001) and had operative times that were 30 minutes shorter (P<.001). General surgeons had lower rates of reoperation (11.8% vs 17.2%; P=.003) and were more likely to treat postoperative leak with interventional means (6.3% vs 3.4%, P=.01). Thoracic surgeons were more likely to treat postoperative leak with reoperation (5.9% vs 3.6%, P=.01). There were no other differences in univariate comparison of outcomes between the two groups, including leak, readmission, and death. General surgery specialty was associated with lower risk of reoperation. Our multivariable model also found no relationship between general surgeon and risk of any complication (odds ratio 1.10; 95% CI .86 to 1.42). Discussion In our large, national database study, we found that outcomes of esophagectomies by general surgeons were comparable with those by thoracic surgeons. General surgeons managed postoperative leaks differently than thoracic surgeons.
Background: Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor that should be managed by an experienced surgical and multidisciplinary group. Our objective was to determine the impact of proficient surgeons and MPM bi-disciplinary review on outcomes of patients with MPM.Methods: Through this cohort study, electronic medical records of 368 adult patients with MPM from 1/1/2009 to 12/31/2020 were reviewed and compared before and after MPM surgeries were regionalized to specialized surgeons and bi-disciplinary review of MPM patient treatment options. We used the Kaplan-Meier method and log-rank tests to compare survival rates by period, by treatment type, and by stage.Patients were followed from cancer diagnosis date until they died or end of study follow-up, whichever occurred first. We also conducted Cox proportional hazards regression model to examine the overall survival (OS) with adjustments for age, histology, stage, and Charlson comorbidity index (CCI).Results: Despite similar staging, more patients received any MPM directed treatment from 2015-2020 compared with those patients from 2009-2014. Specifically, there was an increase in patients who received pleurectomy/decortication (PD) from 2015-2020 compared to those who received PD in 2009-2014.Patients with similar age, CCI, stage, and histology had an increase in OS of 12 months with multimodality therapy (surgery, systemic therapy, +/− radiation) compared to those patients who received no treatment.Conclusions: Consolidating mesothelioma surgery to a specialized surgical team and regular bidisciplinary review of MPM cases to determine appropriate multimodality therapy, increases the incorporation of surgical treatments in the management of patients with MPM.
Background: Intercostal nerve blockade (INB) for thoracic surgery analgesia has gained popularity in practice, but evidence demonstrating its efficacy remains sparse and inconsistent. We investigated the effect of INB with standard bupivacaine (SB) with epinephrine versus liposomal bupivacaine (LB) versus a mixed solution of the two on postoperative pain control and outcomes in video assisted thoracoscopic lobectomy patients.Methods: Since 2014, our practice has shifted from using INBs with SB with epinephrine, to LB, to a mix of the two as the central component of multimodal analgesia after video assisted thoracoscopic surgery. The blocks are performed in a standardized fashion under thoracoscopic visualization consecutively from two rib spaces above to two below the outermost incisions. We retrospectively compared all minimally invasive lobectomies performed at our institution between January 2014 and July 2018 by type of local anesthetic used for INB. We examined median length of stay (LOS), opioid utilization, and subjective pain scores [0-10].Results: Out of 302 minimally invasive lobectomy patients, 34 received SB with epinephrine, 222 received LB alone, and 46 received the mixed solution. LOS was almost a full day shorter in the LB group than in the SB group (34.8 vs. 56.5 hours, P=0.01). There was nearly 25% lower median total morphine equivalent utilization in the mixed solution cohort compared to the LB cohort (−7.1 mg, P=0.02). Additionally, IV morphine equivalent utilization was over 50% lower in the mixed solution group than in the SB with epinephrine group (−10.0 mg, P=0.03).Conclusions: Our study is by far the largest (N=302) to compare types of local anesthetic used for INB within a uniform case population. The reductions in LOS and opiate utilization observed in our study among patients receiving LB-based formulations were both statistically and clinically significant.
Background: Regional analgesia, such as intercostal nerve blockade (INB), is a viable modality for postoperative pain control in thoracic surgery patients. Asian patients have historically been underrepresented in studies of pain responses and pain medication requirements based on race. In this study, we examined the postoperative opioid medications used by Asian and Caucasian patients undergoing videoassisted thoracoscopic surgery (VATS) lobectomy who received different bupivacaine-based INB. Methods: We retrospectively reviewed patients undergoing VATS lobectomy who received standard bupivacaine (SB), liposomal bupivacaine (LB), or liposomal bupivacaine mixed with standard bupivacaine (MIX). Length of stay (LOS), postoperative pain scores, postoperative opioid use (in intravenous morphine equivalents) were evaluated. The Chi-square test was used to compare categorical variables; Student's t-test for normally distributed variables; and the Wilcoxon rank-sum test for non-normally distributed variables.Multivariable linear regression was used to assess opioid use in Asians compared to Caucasians.Results: Of the 239 patients in the cohort, 212 received LB or MIX and 27 received SB. In the LB/MIX group, 48 (22.6%) were Asian and 164 (77.4%) were Caucasian. In the SB group, 7 (25.9%) were Asian and 20 (74.1%) were Caucasian. There were no differences in height, weight, and body mass index (BMI) between the SB and LB/MIX groups, but there was a significant difference in weight and BMI between Asian and Caucasian patients. The median LOS was comparable between the SB and LB/MIX groups. The average 24-hour postoperative pain score in the LB/MIX group was 2.5, and 2.0 and 2.7 in the Asian and Caucasian subgroups, respectively (P<0.01). The median opioid use in the LB/MIX group was 27.2 mg, and 16.9 and 31.1 mg in the Asian and Caucasian subgroups, respectively (P<0.01). On multivariable linear regression analysis adjusting for sex, age, BMI, and bupivacaine type, we found Asians used 25.5 mg less opioids compared to Caucasians (P<0.01).Conclusions: INB with LB or liposomal-standard bupivacaine mix resulted in statistically significant decreased postoperative pain scores and opioid use in Asians compared to Caucasians. There was no difference in LOS between the LB/MIX and SB groups.^ ORCID: 0000-0002-8215-856X.
