RESUMEN
OBJECTIVE: To characterize the current state of mental health within the surgical workforce in the United States. BACKGROUND: Mental illness and suicide is a growing concern in the medical community; however, the current state is largely unknown. METHODS: Cross-sectional survey of the academic surgery community assessing mental health, medical error, and suicidal ideation. The odds of suicidal ideation adjusting for sex, prior mental health diagnosis, and validated scales screening for depression, anxiety, post-traumatic stress disorder (PTSD), and alcohol use disorder were assessed. RESULTS: Of 622 participating medical students, trainees, and surgeons (estimated response rate=11.4%-14.0%), 26.1% (141/539) reported a previous mental health diagnosis. In all, 15.9% (83/523) of respondents screened positive for current depression, 18.4% (98/533) for anxiety, 11.0% (56/510) for alcohol use disorder, and 17.3% (36/208) for PTSD. Medical error was associated with depression (30.7% vs. 13.3%, P <0.001), anxiety (31.6% vs. 16.2%, P =0.001), PTSD (12.8% vs. 5.6%, P =0.018), and hazardous alcohol consumption (18.7% vs. 9.7%, P =0.022). Overall, 13.2% (73/551) of respondents reported suicidal ideation in the past year and 9.6% (51/533) in the past 2 weeks. On adjusted analysis, a previous history of a mental health disorder (aOR: 1.97, 95% CI: 1.04-3.65, P =0.033) and screening positive for depression (aOR: 4.30, 95% CI: 2.21-8.29, P <0.001) or PTSD (aOR: 3.93, 95% CI: 1.61-9.44, P =0.002) were associated with increased odds of suicidal ideation over the past 12 months. CONCLUSIONS: Nearly 1 in 7 respondents reported suicidal ideation in the past year. Mental illness and suicidal ideation are significant problems among the surgical workforce in the United States.

OBJECTIVE: To evaluate whether a machine learning algorithm (i.e. the "NightSignal" algorithm) can be used for the detection of postoperative complications prior to symptom onset after cardiothoracic surgery. SUMMARY BACKGROUND DATA: Methods that enable the early detection of postoperative complications after cardiothoracic surgery are needed. METHODS: This was a prospective observational cohort study conducted from July 2021 to February 2023 at a single academic tertiary care hospital. Patients aged 18 years or older scheduled to undergo cardiothoracic surgery were recruited. Study participants wore a Fitbit watch continuously for at least 1 week preoperatively and up to 90-days postoperatively. The ability of the NightSignal algorithm-which was previously developed for the early detection of Covid-19-to detect postoperative complications was evaluated. The primary outcomes were algorithm sensitivity and specificity for postoperative event detection. RESULTS: A total of 56 patients undergoing cardiothoracic surgery met inclusion criteria, of which 24 (42.9%) underwent thoracic operations and 32 (57.1%) underwent cardiac operations. The median age was 62 (IQR: 51-68) years and 30 (53.6%) patients were female. The NightSignal algorithm detected 17 of the 21 postoperative events a median of 2 (IQR: 1-3) days prior to symptom onset, representing a sensitivity of 81%. The specificity, negative predictive value, and positive predictive value of the algorithm for the detection of postoperative events were 75%, 97%, and 28%, respectively. CONCLUSIONS: Machine learning analysis of biometric data collected from wearable devices has the potential to detect postoperative complications-prior to symptom onset-after cardiothoracic surgery.
RESUMEN
BACKGROUND: With a median age at diagnosis of 70, lung cancer remains a significant public health challenge for older Americans. Surgery is a key component in treating most patients with non-metastatic lung cancer. These patients experience postoperative pain, fatigue, loss of respiratory capacity, and decreased physical function. Data on quality of life (QOL) in older adults undergoing lung cancer surgery is limited, and few interventions are designed to target the needs of older adults and their family caregivers (FCGs). The primary aim of this comparative effectiveness trial is to determine whether telephone-based physical activity coaching before and after surgery will be more beneficial than physical activity self-monitoring alone for older adults and their FCGs. METHODS: In this multicenter comparative effectiveness trial, 382 older adults (≥ 65 years) with lung cancer and their FCGs will be recruited before surgery and randomized to either telephone-based physical activity coaching or physical activity self-monitoring alone. Participants allocated to the telephone-based coaching comparator will receive five telephone sessions with coaches (1 pre and 4 post surgery), an intervention resource manual, and a wristband pedometer. Participants in the self-monitoring only arm will receive American Society of Clinical Oncology (ASCO) physical activity information and wristband pedometers. All participants will be assessed at before surgery (baseline), at discharge, and at days 30, 60, and 180 post-discharge. The primary endpoint is the 6-minute walk test (6MWT) at 30 days post-discharge. Geriatric assessment, lower extremity function, self-reported physical function, self-efficacy, and QOL will also be assessed. DISCUSSION: The trial will determine whether this telephone-based physical activity coaching approach can enhance postoperative functional capacity and QOL outcomes for older adults with lung cancer and their FCGs. Trial results will provide critical findings to inform models of postoperative care for older adults with cancer and their FCGs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT06196008.

BACKGROUND: The outcomes associated with receipt of adjuvant radiation in patients after surgery for MPM are poorly understood. OBJECTIVE: The objective of this study was to use 2 registries to compare the outcomes of patients receiving adjuvant radiation or no radiation after definitive surgery for pathologic stage I-III MPM. METHODS: Patients with resected pathologic stage I-III MPM were identified from the Duke University registry (1996-2016) and National Cancer Database (NCDB) (2004-2015). The primary outcome was overall survival. Propensity score-matched and landmark subgroup analyses were performed. RESULTS: A total of 212 institutional and 1615 NCDB patients met criteria. In both cohorts, patients who underwent radiation were more likely to have margin-negative resection and more advanced pathologic stage. At a landmark time of 4.4 and 4.7 months from surgery, Duke [hazard ratio (HR) 1.14; 95% confidence interval (CI) 0.62-2.11] and NCDB patients (HR 0.97; 95% CI 0.81-1.17) who received adjuvant radiation did not experience improved survival compared to those who did not receive radiation in multivariable analysis. Duke patients who received radiation had similar incidence of recurrence and time to both overall recurrence and ipsilateral recurrence (HR 0.87; 95% CI 0.43-1.77) compared to those who did not. Duke patients experienced 100 grade 1/2, 21 grade 3/4, and one grade 5 toxicity events during radiation. CONCLUSIONS: In this dual registry analysis of patients with resected stage I-III MPM, the receipt of adjuvant hemithoracic radiation was not associated with improved survival compared to no radiation.

OBJECTIVES: We aimed to report efficacy, safety, and health-related quality of life (HRQoL) outcomes of a multidisciplinary treatment approach including supraclavicular thoracic outlet decompression among patients with thoracic outlet syndrome (TOS). BACKGROUND: TOS is a challenging condition where controversy remains in diagnosis and treatment, primarily given a lack of data exploring various treatment approaches and associated patient outcomes. METHODS: Patients who underwent unilateral, supraclavicular thoracic outlet decompression, or pectoralis minor tenotomy for neurogenic, venous, or arterial TOS were identified from a prospectively maintained database. Demography, use of preoperative botulinum toxin injection, and participation in multidisciplinary evaluation were measured. The primary endpoints were composite postoperative morbidity and symptomatic improvement compared with baseline. RESULTS: Among 2869 patients evaluated (2007-2021), 1032 underwent surgery, including 864 (83.7%) supraclavicular decompressions and 168 (16.3%) isolated pectoralis minor tenotomies. Predominant TOS subtypes among surgical patients were neurogenic (75.4%) and venous TOS (23.4%). Most patients (92.9%) with nTOS underwent preoperative botulinum toxin injection; 56.3% reported symptomatic improvement. Before surgical consultation, few patients reported participation in physical therapy (10.9%). The median time from first evaluation to surgery was 136 days (interquartile range: 55, 258). Among 864 patients who underwent supraclavicular thoracic outlet decompression, complications occurred in 19.8%; the most common complication was chyle leak (8.3%). Four patients (0.4%) required revisional thoracic outlet decompression. At a median follow-up of 420 days (interquartile range: 150, 937) 93.3% reported symptomatic improvement. CONCLUSION: Based on low composite morbidity, need for very few revisional operations, and high rates of symptomatic improvement, a multidisciplinary treatment approach including primarily supraclavicular thoracic outlet decompression is safe and effective for patients with TOS.

Host-targeting antivirals (HTAs) have received increasing attention for their potential as broad-spectrum antivirals that pose relatively low risk of developing drug resistance. The repurposing of pharmaceutical drugs for use as antivirals is emerging as a cost- and time- efficient approach to developing HTAs for the treatment of a variety of viral infections. In this study, we used a virus titer method to screen 30 small molecules for antiviral activity against Herpes simplex virus-1 (HSV-1). We found that the small molecule RAF265, an anticancer drug that has been shown to be a potent inhibitor of B-RAF V600E, reduced viral loads of HSV-1 by 4 orders of magnitude in Vero cells and reduced virus proliferation in vivo. RAF265 mediated cytoskeleton rearrangement and targeted the host cell's translation machinery, which suggests that the antiviral activity of RAF265 may be attributed to a dual inhibition strategy. This study offers a starting point for further advances toward clinical development of antivirals against HSV-1.

INTRODUCTION: This study evaluated the treatment of proximal (cervical or upper thoracic) esophageal squamous cell carcinoma (SCC), for which chemoradiation is the recommended therapy. METHODS: Treatment and outcomes of patients with cT1-3N0-1M0 proximal esophageal SCC in the National Cancer Database between 2004 and 2016 was evaluated using logistic regression, Kaplan-Meier analysis, and propensity-score matching. RESULTS: Therapy of 2159 patients was chemoradiation (n = 1500, 69.5%), no treatment (n = 205, 9.5%), surgery (n = 203, 9.4%), radiation alone (n = 190, 8.8%), and chemotherapy alone (n = 61, 2.8%). Factors associated with definitive therapy with either chemoradiation or surgery were younger age, non-Black race, being insured, cervical tumor location, clinical T2 and T3 stage, clinical nodal involvement, and treatment at a research/academic program. Five-year survival was significantly better in patients treated with definitive therapy than patients not treated definitively (34.0% vs. 13.3%, p < 0.001). In multivariable survival analysis, receiving definitive therapy (hazard ratio [HR] 0.39, p = 0.017) was associated with improved survival, while increasing age, male sex, clinical T3 stage, positive clinical nodal involvement, and increasing Charlson Comorbidity Index were associated with worse survival. Esophagectomy was not associated with improved survival in multivariable analysis of the definitive therapy cohort (HR 0.84, p = 0.08) or propensity matched analysis. However, the pathologic complete response was only 33.3% (40/120) for patients who did have an esophagectomy after chemoradiation. CONCLUSIONS: This national analysis supports definitive chemoradiation for not only cervical but also proximal thoracic esophageal SCC. Routine surgery does not appear to be necessary but may have a role in patients with residual disease after chemoradiation.

BACKGROUND: Although SABR is increasingly emerging as an alternative to surgery for node-negative non-small cell lung cancer, there is poor understanding of patients who may most benefit SABR compared to surgery. OBJECTIVE: This study examined the relationship between tumor size and the comparative outcomes of SABR and sublobar resection in patients with node-negative non-small cell lung cancer. RESULTS: A total of 59,949 patients met study criteria: 19,888 (33%) underwent SABR, 33,052 (55%) wedge resection, and 7009 (12%) segmental resection. In multivariable regression, a significant 3-way interaction was found between histology, tumor size, and type of treatment. After stratification by histology, a significant interaction between tumor size and treatment was preserved for patients with adenocarcinoma and squamous cell carcinoma. Sublobar resection was associated with greater survival compared to SABR for tumor sizes greater than 6 and 8 mm for patients with adenocarcinoma and squamous cell carcinoma, respectively. SABR was associated with similar survival compared to sublobar resection for patients with papillary and large cell histology. CONCLUSIONS: In this National Cancer Database analysis, sublobar resection was associated with greater survival compared to SABR for lesions >6or 8 mm in patients with adenocarcinoma or squamous cell carcinoma; however, SABR was associated with similar survival compared to sublobar resection in patients with aggressive tumors including papillary and large cell histology. Histologic diagnosis in patients with even small tumors may enable better treatment selection in those who cannot tolerate lobectomy.

OBJECTIVE: To assess the association between the timing of surgery relative to the development of Covid-19 and the risks of postoperative complications. SUMMARY BACKGROUND DATA: It is unknown whether patients who recovered from Covid-19 and then underwent a major elective operation have an increased risk of developing postoperative complications. METHODS: The risk of postoperative complications for patients with Covid-19 undergoing 18 major types of elective operations in the Covid-19 Research Database was evaluated using multivariable logistic regression. Patients were grouped by time of surgery relative to SARS-CoV-2 infection; that is, surgery performed: (1) before January 1, 2020 ("pre-Covid-19"), (2) 0 to 4âweeks after SARS-CoV-2 infection ("peri-Covid-19"), (3) 4 to 8âweeks after infection ("early post-Covid-19"), and (4) ≥8âweeks after infection ("late post-Covid-19"). RESULTS: Of the 5479 patients who met study criteria, patients with peri-Covid-19 had an elevated risk of developing postoperative pneumonia [adjusted odds ratio (aOR), 6.46; 95% confidence interval (CI): 4.06-10.27], respiratory failure (aOR, 3.36; 95% CI: 2.22-5.10), pulmonary embolism (aOR, 2.73; 95% CI: 1.35-5.53), and sepsis (aOR, 3.67; 95% CI: 2.18-6.16) when compared to pre-Covid-19 patients. Early post-Covid-19 patients had an increased risk of developing postoperative pneumonia when compared to pre-Covid-19 patients (aOR, 2.44; 95% CI: 1.20-4.96). Late post-Covid-19 patients did not have an increased risk of postoperative complications when compared to pre-Covid-19 patients. CONCLUSIONS: Major, elective surgery 0 to 4âweeks after SARS-CoV-2 infection is associated with an increased risk of postoperative complications. Surgery performed 4 to 8âweeks after SARS-CoV-2 infection is still associated with an increased risk of postoperative pneumonia, whereas surgery 8 weeks after Covid-19 diagnosis is not associated with increased complications.

The transmission of most respiratory pathogens, including SARS-CoV-2, occurs via virus-containing respiratory droplets, and thus, factors that affect virus viability in droplet residues on surfaces are of critical medical and public health importance. Relative humidity (RH) is known to play a role in virus survival, with a U-shaped relationship between RH and virus viability. The mechanisms affecting virus viability in droplet residues, however, are unclear. This study examines the structure and evaporation dynamics of virus-containing saliva droplets on fomites and their impact on virus viability using four model viruses: vesicular stomatitis virus, herpes simplex virus 1, Newcastle disease virus, and coronavirus HCoV-OC43. The results support the hypothesis that the direct contact of antiviral proteins and virions within the "coffee ring" region of the droplet residue gives rise to the observed U-shaped relationship between virus viability and RH. Viruses survive much better at low and high RH, and their viability is substantially reduced at intermediate RH. A phenomenological theory explaining this phenomenon and a quantitative model analyzing and correlating the experimentally measured virus survivability are developed on the basis of the observations. The mechanisms by which RH affects virus viability are explored. At intermediate RH, antiviral proteins have optimal influence on virions because of their largest contact time and overlap area, which leads to the lowest level of virus activity.
RESUMEN
BACKGROUND: A Medicare effect has been described to account for increased health care utilization occurring at the age of 65 years. The existence of such an effect in cancer care, where it would be most likely to reduce mortality, has been unclear. METHODS: Patients aged 61 to 69 years who were diagnosed with lung, breast, colon, or prostate cancer from 2004 to 2016 were identified with the Surveillance, Epidemiology, and End Results database and were dichotomized on the basis of eligibility for Medicare (61-64 vs 65-69 years). With age-over-age (AoA) percent change calculations, trends in cancer diagnoses and staging were characterized. After matching, uninsured patients who were 61 to 64 years old (pre-Medicare group) were compared with insured patients who were 65 to 69 years old (post-Medicare group) with respect to cancer-specific mortality. RESULTS: In all, 134,991 patients were identified with lung cancer, 175,558 were identified with breast cancer, 62,721 were identified with colon cancer, and 238,823 were identified with prostate cancer. The AoA growth in the number of cancer diagnoses was highest at the age of 65 years in comparison with all other ages within the decade for all 4 cancers (P < .01, P < .001, P < .01, and P < .001, respectively). In a comparison of diagnoses at the age of 65 years with those in the 61- to 64-year-old cohort, the greatest difference for all 4 cancers was seen in stage I. In matched analyses, the 5-year cancer-specific mortality was worse for lung (86.3% vs 78.5%; P < .001), breast (32.7% vs 11.0%; P < .001), colon (57.1% vs 35.6%; P < .001), and prostate cancer (16.9% vs 4.8%; P < .001) in the uninsured pre-Medicare group than the insured post-Medicare group. CONCLUSIONS: The age threshold of 65 years for Medicare eligibility is associated with more cancer diagnoses (particularly stage I), and this results in lower long-term cancer-specific mortality for all cancers studied. LAY SUMMARY: Contributing to the current debate regarding Medicare for all, this study shows that the expansion of Medicare would improve cancer outcomes for the near elderly.

OBJECTIVE: To compare outcomes after open versus thoracoscopic (VATS) lobectomy for clinical stage II (cN1) non-small-cell lung cancer (NSCLC). BACKGROUND: There have been no published studies evaluating the impact of a VATS approach to lobectomy for N1 NSCLC on short-term outcomes and survival. METHODS: Outcomes of patients with clinical T1-2, N1, M0 NSCLC who underwent lobectomy without induction therapy in the National Cancer Data Base (2010-2012) were evaluated using multivariable Cox proportional hazards modeling and propensity score-matched analysis. RESULTS: Median follow-up of 1559 lobectomies (1204 open and 355 VATS) was 43.2 months. The VATS approach was associated with a shorter median hospitalization (5 vs 6 d, P < 0.001) than the open approach. There were no significant differences between the VATS and open approach with regard to nodal upstaging (12.0% vs 10.5%, P = 0.41), 30-day mortality (2.3% vs 3.1%, P = 0.31), and overall survival (5-yr survival: 48.6% vs 48.7%, P = 0.76; multivariable-adjusted HR for VATS approach: 1.08, 95% CI: 0.90-1.30, P = 0.39). A propensity score-matched analysis of 334 open and 334 VATS patients who were well matched by 14 common prognostic covariates, including tumor size, and comorbidities, continued to show no significant differences in nodal upstaging, 30-day mortality, and 5-year survival between the VATS and open groups. CONCLUSION: In this national analysis, VATS lobectomy was used in the minority of N1 NSCLC cases but was associated with shorter hospitalization and similar nodal upstaging rates, 30-day mortality, and long-term survival when compared to open lobectomy. These findings suggest thoracoscopic techniques are feasible for the treatment of stage II (cN1) NSCLC.

OBJECTIVE: The purpose of this study is to evaluate the impact of extended delay to surgery for stage I NSCLC. SUMMARY OF BACKGROUND DATA: During the COVID-19 pandemic, patients with NSCLC may experience delays in care, and some national guidelines recommend delays in surgery by >3âmonths for early NSCLC. METHODS: Using data from the National Lung Screening Trial, a multi-center randomized trial, and the National Cancer Data Base, a multi-institutional oncology registry, the impact of "early" versus "delayed" surgery (surgery received 0-30 vs 90-120âdays after diagnosis) for stage I lung adenocarcinoma and squamous cell carcinoma (SCC) was assessed using multivariable Cox regression analysis with penalized smoothing spline functions and propensity score-matched analyses. RESULTS: In Cox regression analysis of the National Lung Screening Trial (n = 452) and National Cancer Data Base (n = 80,086) cohorts, an increase in the hazard ratio was seen the longer surgery was delayed. In propensity score-matched analysis, no significant differences in survival were found between early and delayed surgery for stage IA1 adenocarcinoma and IA1-IA3 SCC (all P > 0.13). For stage IA2-IB adenocarcinoma and IB SCC, delayed surgery was associated with worse survival (all P < 0.004). CONCLUSIONS: The mortality risk associated with an extended delay to surgery differs across patient subgroups, and difficult decisions to delay care during the COVID-19 pandemic should take substage and histologic subtype into consideration.

OBJECTIVE: To evaluate the overall survival of patients with operable stage IA non-small-cell lung cancer (NSCLC) who undergo "early" SBRT (within 0-30 days after diagnosis) versus "delayed" surgery (90-120 days after diagnosis). SUMMARY OF BACKGROUND DATA: During the COVID-19 pandemic, national guidelines have recommended patients with operable stage IA NSCLC to consider delaying surgery by at least 3 months or, alternatively, to undergo SBRT without delay. It is unknown which strategy is associated with better short- and long-term outcomes. METHODS: Multivariable Cox proportional hazards modeling and propensity score-matched analysis was used to compare the overall survival of patients with stage IA NSCLC in the National Cancer Data Base from 2004 to 2015 who underwent "early" SBRT (0-30 days after diagnosis) versus that of patients who underwent "delayed" wedge resection (90-120 days after diagnosis). RESULTS: During the study period, 570 (55%) patients underwent early SBRT and 475 (45%) underwent delayed wedge resection. In multivariable analysis, delayed resection was associated with improved survival [adjusted hazard ratio 0.61; (95% confidence interval (CI): 0.50-0.76)]. Propensity-score matching was used to create 2 groups of 279 patients each who received early SBRT or delayed resection that were well-matched with regard to baseline characteristics. The 5-year survival associated with delayed resection was 53% (95% CI: 45%-61%) which was better than the 5-year survival associated with early SBRT (31% [95% CI: 24%-37%]). CONCLUSION: In this national analysis, for patients with stage IA NSCLC, extended delay of surgery was associated with improved survival when compared to early treatment with SBRT.

OBJECTIVE: The objective of this study was to compare the long-term survival of open versus thoracoscopic (VATS) lobectomy for early stage non-small-cell lung cancer (NSCLC). BACKGROUND: Data from national studies on long-term survival for VATS versus open lobectomy are limited. METHODS: Outcomes of patients who underwent open versus VATS lobectomy for clinical T1-2, N0, M0 NSCLC in the National Cancer Data Base were evaluated using propensity score matching. RESULTS: The median follow-up of 7114 lobectomies (5566 open and 1548 VATS) was 52.0 months. The VATS approach was associated with a better 5-year survival when compared to the open approach (66.0% vs. 62.5%, P = 0.026). Propensity score matching resulted in 1464 open and 1464 VATS patients who were well matched by 14 common prognostic covariates including tumor size and comorbidities. After propensity score matching, the VATS approach was associated with a shorter median length of stay (5 vs. 6 days, P < 0.001). The VATS approach was not significantly different compared with the open approach with regard to nodal upstaging (11.6% vs 12.3%, P = 0.53), 30-day mortality (1.7% vs 2.3%, P = 0.50) and 5-year survival (66.3% vs 65.8%, P = 0.92). CONCLUSIONS: In this national analysis, VATS lobectomy was used in the minority of patients with stage I NSCLC. VATS lobectomy was associated with shorter length of stay and noninferior long-term survival when compared with open lobectomy. These results support previous findings from smaller single- and multi-institutional studies that suggest that VATS does not compromise oncologic outcomes when used for early-stage lung cancer and suggest the need for broader implementation of VATS techniques.

BACKGROUND: Models for predicting the survival outcomes of stage I non-small-cell lung cancer (NSCLC) defined by the newly released 8th edition TNM staging system are scarce. This study aimed to develop a nomogram for predicting the cancer-specific survival (CSS) of these patients and identifying individuals with a higher risk for CSS. METHODS: A total of 30,475 NSCLC cases were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. We identified and integrated the risk factors to build a nomogram. The model was subjected to bootstrap internal validation with the SEER database, and external validation with a multicenter cohort of 1133 patients from China. The difference in the impact of adjuvant chemotherapy on model-defined high- and low-risk patients was examined using the National Cancer Database (NCDB). RESULTS: Eight independent prognostic factors were identified and integrated into the model. The calibration curves showed good agreement. The concordance index (C-index) of the nomogram was higher than that of the staging system (IA1, IA2, IA3, and IB) (internal validation set 0.63 vs. 0.56; external validation set 0.66 vs. 0.55; both p < 0.01). Specifically, 21.7% of stage IB patients (7.5% of all stage I) were categorized into the high-risk group (score > 30). There was a significant interaction effect between the adjuvant chemotherapy and risk groups in the NCDB cohort (p = 0.003). CONCLUSIONS: We established a practical nomogram to predict CSS for 8th edition stage I NSCLC. A prospective study is warranted to determine its role in identifying adjuvant chemotherapy candidates.

OBJECTIVE: To determine whether surgery with adjuvant chemotherapy offers a survival advantage over concurrent chemoradiation for patients with cT1-2N0M0 small cell lung cancer (SCLC). BACKGROUND: Although surgery with adjuvant chemotherapy is the recommended treatment for patients with cT1-2N0M0 SCLC per international guidelines, there have been no prospective or retrospective studies evaluating the impact of surgery versus optimal medical management for cT1-2N0M0 SCLC. METHODS: Outcomes of patients with cT1-2N0M0 SCLC who underwent surgery with adjuvant chemotherapy or concurrent chemoradiation in the National Cancer Data Base (2003-2011) were evaluated using Cox proportional hazards analyses and propensity-score-matched analyses. RESULTS: During the study period, 681 (30%) patients underwent surgery with adjuvant chemotherapy and 1620 (70%) underwent concurrent chemoradiation. After propensity-score matching, all 14 covariates were well balanced between the surgery (n = 501) and concurrent chemoradiation (n = 501) groups. Surgery was associated with a higher overall survival (OS) than concurrent chemoradiation (5-year OS 47.6% vs 29.8%, P < 0.01). To minimize selection bias due to comorbidities, we limited the propensity-matched analysis to 492 patients with no comorbidities; surgery remained associated with a higher OS than concurrent chemoradiation (5-year OS 49.2% vs 32.5%, P < 0.01). CONCLUSIONS: In a national analysis, surgery with adjuvant chemotherapy was used in the minority of patients for early stage SCLC. Surgery with adjuvant chemotherapy for node-negative SCLC was associated with improved long-term survival when compared to concurrent chemoradiation. These results suggest a significant underuse of surgery among patients with early stage SCLC and support an increased role of surgery in multimodality therapy for cT1-2N0M0 SCLC.

BACKGROUND: There is limited data guiding treatment for positive margins following lobectomy for early-stage non-small cell lung cancer (NSCLC). Using data from the National Cancer Data Base, we sought to determine whether radiation therapy following lobectomy for stage I or II NSCLC was associated with improved overall survival in patients with positive margins. METHODS: Patients who underwent lobectomy without induction therapy for stage I or II NSCLC (1998-2006) with positive resection margins were selected. Patients were stratified by administration of radiation therapy following surgery, and overall survival was estimated using the Kaplan-Meier method. The association between radiation therapy and survival was adjusted for nonrandom treatment selection using Cox proportional hazards regression modeling. RESULTS: Positive margins were recorded in 1934 of 49,563 (3.9%) patients who underwent lobectomy for stage I or II NSCLC. Positive margin status was associated with significantly worse 5-year survival (34.5% versus 57.2%, P < 0.001). After selection of patients with positive margins and known radiation status and exclusion of patients who had upstaged disease or received radiation therapy for palliative indications, radiation therapy was used in 579 of 1579 patients (38.2%) but was not associated with a significant difference in the likelihood of death during subsequent follow-up (hazard ratio: 1.10, 95% confidence interval: 0.90, 1.35). CONCLUSIONS: Positive margins following lobectomy for stage I or II NSCLC are associated with reduced 5-year survival. Postsurgical radiation is not strongly associated with an improvement in overall survival among these patients.

BACKGROUND: This study was conducted to determine how malignant pleural mesothelioma (MPM) histology was associated with the use of surgery and survival. METHODS: Overall survival of patients with stage I-III epithelioid, sarcomatoid, and biphasic MPM in the Surveillance, Epidemiology, and End Results database from 2004-2010 was evaluated using multivariate Cox proportional hazards models. RESULTS: Of 1183 patients who met inclusion criteria, histologic subtype was epithelioid in 811 patients (69%), biphasic in 148 patients (12%), and sarcomatoid in 224 patients (19%). Median survival was 14 mo in the epithelioid group, 10 mo in the biphasic group, and 4 mo in the sarcomatoid group (P < 0.01). Cancer-directed surgery was used more often in patients with epithelioid (37%, 299/811) and biphasic (44%, 65/148) histologies as compared with patients with sarcomatoid histology (26%, 58/224; P < 0.01). Among patients who underwent surgery, median survival was 19 mo in the epithelioid group, 12 mo in the biphasic group, and 4 mo in the sarcomatoid group (P < 0.01). In multivariate analysis, surgery was associated with improved survival in the epithelioid group (hazard ratio [HR] 0.72; P < 0.01) but not in biphasic (HR 0.73; P = 0.19) or sarcomatoid (HR 0.79; P = 0.18) groups. CONCLUSIONS: Cancer-directed surgery is associated with significantly improved survival for MPM patients with epithelioid histology, but patients with sarcomatoid and biphasic histologies have poor prognoses that may not be favored by operative treatment. The specific histology should be identified before treatment, so that surgery can be offered to patients with epithelioid histology, as these patients are most likely to benefit.
