RESUMEN
BACKGROUND: Recent data based on large databases show that bowel preparation (BP) is associated with improved outcomes in patients undergoing elective colorectal surgery. However, it remains unclear whether BP in elective colectomies would lead to similar results in patients with diverticulitis. The purpose of this study was to investigate whether bowel preparation affected the surgical site infections (SSI) and anastomotic leakage (AL) in patients with diverticulitis undergoing elective colectomies. STUDY DESIGN: We identified 16,380 diverticulitis patients who underwent elective colectomies from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) colectomy targeted database (2012-2017). Multivariate logistic regression models were employed to investigate the impact of different bowel preparation strategies on postoperative complications, including SSI and AL. RESULTS: In the identified population, a total of 2524 patients (15.4%) received no preparation (NP), 4715 (28.8%) mechanical bowel preparation (MBP) alone, 739 (4.5%) antibiotic bowel preparation (ABP) alone, and 8402 (51.3%) MBP + ABP. Compared to NP, patients who received any type of bowel preparations showed a significantly decreased risk of SSI and AL after adjustment for potential confounders (SSI: MBP [OR = 0.82, 95%CI: 0.70-0.96], ABP [0.69, 95%CI: 0.52-0.92]; AL: MBP [OR = 0.66, 95%CI: 0.51-0.86], ABP [0.56, 95%CI: 0.34-0.93]), where the combination type of MBP + ABP had the strongest effect (SSI:OR = 0.58, 95%CI:0.50-0.67; AL:OR = 0.46, 95%CI:0.36-0.59). The significantly decreased risk of 30-day mortality was observed in the bowel preparation of MBP + ABP only (OR = 0.32, 95%CI: 0.13-0.79). After the further stratification by surgery procedures, patients who received MBP + ABP showed consistently lower risk for both SSI and AL when undergoing open and laparoscopic surgeries (Open: SSI [OR = 0.51, 95%CI: 0.37-0.69], AL [OR = 0.47, 95%CI: 0.25-0.91]; Laparoscopic: SSI [OR = 0.58, 95%CI: 0.47-0.72, AL [OR = 0.49, 95%CI: 0.35-0.68]). CONCLUSIONS: MBP + ABP for diverticulitis patients undergoing elective open or laparoscopic colectomies was associated with decreased risk of SSI, AL, and 30-day mortality. Benefits of MBP + ABP for diverticulitis patients underwent robotic surgeries warrant further investigation.

INTRODUCTION: There are currently two recommended radiation strategies for clinical stage III NSCLC: a lower "preoperative" (45-54 Gy) and a higher "definitive/nonsurgical" (60-70 Gy) dose. We sought to determine if definitive radiation doses should be used in the preoperative setting given that many clinical stage III patients planned for surgery are ultimately managed with chemoradiation alone. METHODS: Using the National Cancer Database data from 2006 to 2016, we performed a comparative effectiveness analysis of stage III N2 patients who received chemoradiotherapy. Patients were stratified into subgroups across 2 parameters: (1) radiation dose: lower (45-54 Gy) and higher (60-70 Gy); and (2) the use of surgery (i.e., surgical and nonsurgical treatment approaches). Long-term survival and perioperative outcomes were evaluated using multivariable Cox proportional hazards and logistic regression models. RESULTS: A cohort of 961 patients received radiation before surgery including 321 who received a higher dose and 640 who received a lower dose. A higher preoperative dose revealed similar long-term mortality risk (hazard ratio = 0.99, 95% confidence interval: 0.82-1.21, p = 0.951) compared with a lower dose. There was no significant association between radiation dose and 90-day mortality (p = 0.982), 30-day readmission (p = 0.931), or prolonged length of stay (p = 0.052) in the surgical cohort. A total of 17,904 clinical-stage IIIA-N2 patients were treated nonsurgically, including 15,945 receiving higher and 1959 treated with a lower dose. A higher dose was associated with a reduction in long-term mortality risk (hazard ratio = 0.64, 95% confidence interval: 0.60-0.67, p < 0.001) compared with a lower dose. CONCLUSIONS: For clinical stage III NSCLC, the administration of 60 to 70 Gy of radiation seems to be more effective than the lower dose for nonsurgical patients without compromising surgical safety for those that undergo resection. This evidence supports the implementation of 60 to 70 Gy as a single-dose strategy for both preoperative and definitive chemoradiotherapy.
RESUMEN
BACKGROUND: Primary lung sarcoma (PLS) represents a rare form of lung cancer with outcomes that are poorly defined by small datasets. We sought to characterize clinical and pathological characteristics and associated survival within the surgically managed subgroup of these unusual pulmonary malignancies. METHODS: We performed a retrospective analysis of the National Cancer Database (NCDB), which was queried for cases of surgically managed PLS diagnosed between 2004-2014. Adjusted mortality was evaluated in a multivariable Cox proportional hazards model and compared to surgically manage non-small cell lung cancer (NSCLC) patients from the same time period. RESULTS: A total of 695 patients with surgically managed PLS were identified with 37 different histologic subtypes. The mean age of diagnosis was 57.7 years (range, 18-90 years). A majority of patients underwent surgical resection alone (64.3%) with an estimated 5-year overall survival (OS) of 51%. The multivariable Cox model identified increasing age, Charlson-Deyo score ≥2, high tumor grade, tumor size >5 cm, positive margins, and positive lymph nodes to be associated with higher risk for mortality (P<0.05). Compared to 101,428 surgically managed patients with adenocarcinoma, PLS patients were younger with fewer comorbidities but had larger tumors, higher grade tumors, and were more likely node negative (P<0.001). Surgery with adjuvant chemotherapy was associated with worse survival than surgery alone (HR 1.41, 95% CI: 1.05-1.88). The extent of parenchymal resection (lobar vs. sublobar) was not predictive for survival. Five-year OS was lower for patients with PLS (44%) than adenocarcinoma (53.6%, P<0.001). CONCLUSIONS: The survival of surgically managed PLS is reasonable and impacted by tumor attributes and the completeness of surgical resection. Further study to define the role of multimodal therapy is indicated.
RESUMEN
BACKGROUND: Nearly half of operative mortalities occur outside the traditionally studied 30-day period after surgery. To identify additional opportunities to improve surgical safety, the circumstances of deaths occurring 31-90 days after complex cancer surgery are analyzed. PATIENTS AND METHODS: Patients aged ≥ 65 years who died within 90 days of complex cancer surgery for nonmetastatic cancer were analyzed in the Surveillance, Epidemiology, and End Results (SEER)-Medicare and the Connecticut Tumor Registry (CTR) databases. RESULTS: Of the 36,114 patients undergoing complex cancer surgery from 2004 to 2013 in SEER-Medicare, 1367 (3.8%) died within 31-90 days ("late mortalities"). Seventy-eight percent of late mortalities were readmitted prior to death. The highest proportion of late mortalities occurred during a readmission (49%), and 11% were never discharged from their index admission. Cause of death (COD) was largely attributed to the malignancy itself (56%), which is unlikely to be the underlying cause. Of the noncancer COD, cardiac causes were most frequent (34%), followed by pulmonary causes (18%). Death was rarely attributed to thromboembolic disease (< 1%). The CTR provided location of death, which was most commonly in a hospital (65%) or nursing facility (20%); death at home was rare (6%). CONCLUSIONS: The vast majority of patients dying between 31 and 90 days of surgery were admitted to a hospital or nursing facility at the time of their death after initially being discharged, and few patients died at home. Greater clarity in death documentation is needed to identify specific opportunities to rescue patients from fatal complications arising in the later postoperative period.

BACKGROUND: Atypical pulmonary carcinoid tumors represent a subset of non-small cell lung cancer; however, their relative infrequency has left prognosis, management and long-term survival associated with atypical carcinoids, incompletely characterized. METHODS: Patients aged 18 years or more diagnosed with atypical or typical pulmonary carcinoid between 2010 and 2015 within the National Cancer Database were evaluated. Survival was measured using Kaplan-Meier survival and multivariable Cox proportional hazards regression, adjusting for patient and tumor attributes. RESULTS: A total of 816 atypical and 5688 typical carcinoid patients were identified in the cohort. Patients with atypical carcinoids tended to be older, have larger tumors, and later stage disease. The unadjusted overall 5-year survival for atypical carcinoid patients was 84%, 74%, 52%, and 51% for stages I, II, III, and IV, respectively. The unadjusted 5-year survival for typical carcinoids was 93%, 93%, 89%, and 87% for stages I, II, III, and IV, respectively. Nodal upstaging (ie, lymph node metastases identified in surgical specimens of clinically staged N0 patients) was seen in 16% of atypical and 7% of typical carcinoid patients. Increasing age, comorbidities, and stage were identified as significant predictors of mortality for atypical patients in multivariable analysis. Extent of surgical resection (lobectomy vs sublobar) was not identified as a predictor of survival for atypical carcinoid. CONCLUSIONS: Atypical carcinoid tumors represent a distinct subset of carcinoid tumors, with a tendency toward more aggressive behavior. Further study of the optimal surgical management is warranted.

BACKGROUND: The Centers for Medicare and Medicaid Services (CMS) developed risk-adjusted "Star Ratings," which serve as a guide for patients to compare hospital quality (1 star = lowest, 5 stars = highest). Although star ratings are not based on surgical care, for many procedures, surgical outcomes are concordant with star ratings. In an effort to address variability in hospital mortality after complex cancer surgery, the use of CMS Star Ratings to identify the safest hospitals was evaluated. METHODS: Patients older than 65 years of age who underwent complex cancer surgery (lobectomy, colectomy, gastrectomy, esophagectomy, pancreaticoduodenectomy) were evaluated in CMS Medicare Provider Analysis and Review files (2013-2016). The impact of reassignment was modeled by applying adjusted mortality rates of patients treated at 5-star hospitals to those at 1-star hospitals (Peters-Belson method). RESULTS: There were 105 823 patients who underwent surgery at 3146 hospitals. The 90-day mortality decreased with increasing star rating (1 star = 10.4%, 95% confidence interval [CI] = 9.8% to 11.1%; and 5 stars = 6.4%, 95% CI = 6.0% to 6.8%). Reassignment of patients from 1-star to 5-star hospitals (7.8% of patients) was predicted to save 84 Medicare beneficiaries each year. This impact varied by procedure (colectomy = 47 lives per year; gastrectomy = 5 lives per year). Overall, 2189 patients would have to change hospitals each year to improve outcomes (26 patients moved to save 1 life). CONCLUSIONS: Mortality after complex cancer surgery is associated with CMS Star Rating. However, the use of CMS Star Ratings by patients to identify the safest hospitals for cancer surgery would be relatively inefficient and of only modest impact.
RESUMEN
Importance: Hospital networks formed around top-ranked cancer hospitals represent an opportunity to optimize complex cancer care in the community. Objective: To compare the short- and long-term survival after complex cancer treatment at top-ranked cancer hospitals and the affiliates of top-ranked hospitals. Design, Setting, and Participants: This cohort study was conducted using data from the unabridged version of the National Cancer Database. Included patients were individuals 18 years or older who underwent surgical treatment for esophageal, gastric, lung, pancreatic, colorectal, or bladder cancer diagnosed between January 1, 2012, and December 31, 2016. Patient outcomes after complex surgical procedures for cancer at top-ranked cancer hospitals (as ranked in top 50 by US News and World Report) were compared with outcomes at affiliates of top-ranked cancer hospitals (affiliation listed in American Hospitals Association survey and confirmed by search of internet presence). Data were analyzed from July through December 2019. Exposures: Undergoing complex cancer treatment at a top-ranked cancer hospital or an affiliated hospital. Main Outcomes and Measures: The association of affiliate status with short-term survival (ie, 90-day mortality) was compared using logistic regression, and the association of affiliate status with long-term survival was compared using time-to-event models, adjusting for patient demographic, payer, clinical, and treatment factors. Results: Among 119â¯834 patients who underwent surgical treatment for cancer, 79â¯981 patients (66.7%) were treated at top-ranked cancer hospitals (median [interquartile range] age, 66 [58-74] years; 40â¯910 [54.9%] men) and 39â¯853 patients (33.3%) were treated at affiliate hospitals (median [interquartile range] age, 69 [60-77] years; 19â¯004 [50.0%] men). In a pooled analysis of all cancer types, adjusted perioperative mortality within 90 days of surgical treatment was higher at affiliate hospitals compared with top-ranked hospitals (odds ratio, 1.67 [95% CI, 1.49-1.89]; P < .001). Adjusted long-term survival following cancer treatment at affiliate hospitals was only 77% that of top-ranked hospitals (time ratio, 0.77 [95% CI, 0.72-0.83]; P < .001). The survival advantage was not fully explained by differences in annual surgical volume, with both long- and short-term survival remaining superior at top-ranked hospitals even after models were adjusted for volume. Conclusions and Relevance: These findings suggest that short- and long-term survival after complex cancer treatment were superior at top-ranked hospitals compared with affiliates of top-ranked hospitals. Further study of cancer care within top-ranked cancer networks could reveal collaborative opportunities to improve survival across a broad contingent of the US population.

BACKGROUND: Up to 20% of clinical stage I lung cancer patients harbor lymph node metastases that go undetected (missed) during the clinical staging evaluation. We investigated to what degree the addition of invasive nodal staging procedures to imaging, as currently practiced, prevents radiographically occult nodal metastases from being missed during the clinical staging evaluation. METHODS: Treatment-naive patients, imaged by positron emission tomography and computed tomography, who underwent lobectomy for clinical stage I lung cancer from 2012 to 2017 in The Society of Thoracic Surgeons General Thoracic Surgery Database were studied. Rates of missed nodal metastases (MNM) (ie, nodal metastases in lobectomy specimens undetected during clinical staging evaluation) were determined. Risk factors were assessed with multivariable modeling. RESULTS: Of the 30,685 clinical stage I patients identified, 3895 (12.7%) underwent preoperative endobronchial ultrasound and 3341 (10.9%) underwent mediastinoscopy. Invasive staging was more common with tumors > 2 cm (66.4% vs 50.2%, P < .001) and squamous histology (26.9% vs 16.9%, P < .001). MNM were discovered in 14.7% of patients, including 20.1% of patients (95% confidence interval, 18.8%-21.5%) who had undergone endobronchial ultrasound and 18.2% (95% confidence interval, 16.7%-19.6%) who had undergone mediastinoscopy. Hilar nodes were most often "missed" (9.5%). Using cut-points in tumor size, histology, laterality, and age, patients could be stratified into particularly high-risk (25% MNM) and low-risk (6% MNM) cohorts. CONCLUSIONS: Substantial risk of occult lymph node metastases persists in patients with clinical stage I lung cancer despite negative invasive nodal staging, positron emission tomography, and computed tomography. In the absence of a thorough surgical nodal evaluation, early-stage lung cancer patients are at risk of under-treatment.

BACKGROUND: The only possibility for cure in patients with colon adenocarcinoma (CAC) with isolated liver metastases (ILM) is resection of both primary and metastatic tumors. Little is known about the implication of the sequence in which a colectomy and hepatectomy are performed on outcomes. This study analyzes whether resection sequence impacts clinical outcomes. METHODS: The National Cancer Database was queried for CAC cases with hepatic metastases from 2010-2015 with exclusion of extrahepatic metastases. We compared patients treated with a liver-first approach (LFA) to those treated with a colectomy-first or simultaneous approach using Kaplan Meier and multivariable Cox proportional hazards analysis. RESULTS: In 21,788 CAC patients identified, the LFA was uncommon (2%), but was associated with higher rates of completion resection of remaining tumor (41% vs. 22%, P<0.001). Patients selected for LFA were younger, less comorbid, and more commonly received upfront chemotherapy (P<0.05). The LFA was associated with increased median survival [34 months, 95% CI (30.5-39.6 months) vs. 24 months, 95% CI (23.7-24.6 months), logrank P<0.001] and decreased risk of death [HR 0.783; 95% CI (0.67-0.89), P=0.001]. CONCLUSIONS: The LFA to CAC with synchronous ILM is uncommon but is associated with greater likelihood of receiving chemotherapy prior to surgery and increased survival in selected candidates.
RESUMEN
BACKGROUND: Signet ring cell adenocarcinoma (SRC) is a less common histologic variant of esophageal adenocarcinoma (ACA). The low frequency of SRC limits the ability to make data-driven clinical recommendations for these patients. METHODS: The National Cancer Database was queried for adult patients with clinical stage I, II, or III adenocarcinoma of the noncervical esophagus diagnosed between 2004 and 2015 and stratified by SRC versus all other ACA variants. Cox proportional hazard regression models were adjusted for patient, tumor, and treatment characteristics. The role of surgery in SRC was evaluated among patients treated with chemoradiation alone versus chemoradiation with esophagectomy. RESULTS: Of the 681 SRC and 13,543 ACA patients who underwent esophagectomy, no significant differences in age, sex, race, or comorbidities were identified. Patients with SRC were more likely to have high-grade tumors (84% vs 41%, P < .001) and stage III tumors (47% vs 39%, P < .001) compared with patients with ACA. Complete (R0) resection was less common in SRC (81% vs 90%, P < .001). Adjusted 5-year mortality risk from surgery was higher for SRC patients compared with ACA patients (hazard ratio, 1.242; 95% confidence interval, 1.126-1.369; P < .001). Among SRC tumors, chemoradiation with esophagectomy was associated with superior survival (hazard ratio, 0.429; 95% confidence interval, 0.339-0.546; P < .001) compared with chemoradiation alone. CONCLUSIONS: Among surgically managed patients SRC appears to have a worse prognosis than ACA, which may reflect the tendency of SRC tumors to be higher grade and more locally advanced. However SRC histology does not appear to diminish the role of esophagectomy in the management of locoregionally confined esophageal cancer.

OBJECTIVE: Physician burnout, including surgical trainees, is multidimensional. Input variables used to predict burnout include grit, exhaustion, and financial stress. Each instrument has intrinsic limitations of scope and strength. We hypothesize that bioinformatics methods borrowed from oncogenetics may allow meta-analysis of existing predictive tools to improve identification of subpopulations at highest risk of burnout. DESIGN: A composite survey was created using widely accepted instruments: demographic factors, burnout using the Single-Item Maslach Burnout Inventory Emotional Exhaustion Measure, grit using the Duckworth Grit Scale, occupational fatigue using the Occupational Fatigue Exhaustion/Recovery Scale, financial well-being, perceptions of physician leadership, and attitudes towards robotic surgery. Surveys were analyzed using k-means analysis and supervised/unsupervised clustering. SETTING: Yale General Surgery Residency. PARTICIPANTS: Survey participants consisted of Yale General Surgery residents. Of 70 residents, 53 responded (75.7%). Males comprised 57.1% and each postgraduate year had majority representation, 68.8% to 100%. RESULTS: Unsupervised hierarchical clustering showed heterogeneous resident answer patterns and suggested clusters of responders. To define groups of dissimilar responders, we performed k-means clustering, testing 15 iterations with 50 attempts. The analysis revealed 3 discrete clusters of responders with differential risk for burnout (pâ¯=â¯0.021). The highest risk group demonstrated the lowest grit score, low interest in innovation and leadership, higher financial stress, and concordantly, the highest rates of anxiety, dread, and self-reported burnout. (pâ¯=â¯0.0004; 0.0014; 0.1217; 0.0625; 0.021; 0.0011; 0.0224) CONCLUSIONS: The limited scope of common tools aiming to predict burnout constrains their utility. The machine-learning technique of cluster analysis organizes compound data to describe complex outcomes such as oncologic risks. We apply this analysis technique to create a composite predictor of burnout among surgical residents. Our method determines subgroups of residents sharing unique traits predictive of burnout. Residencies can use this tool to allocate resources to best support resident well-being.

BACKGROUND: Surgical futility is poorly defined. However, there are patients with extremely high preoperative risk who still undergo surgery and ultimately die, suggesting futile care. To further explore surgical futility, we examined the incidence and factors associated with extreme-risk patients undergoing major emergency general surgery with early death. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for all adults undergoing colectomy, small bowel resection, control of bleeding ulcer, lysis of adhesion, and exploratory laparotomy between 2007 and 2015. Extreme-risk was defined as having an estimated mortality risk ≥75% using the National Surgical Quality Improvement Program mortality-risk calculator. Futile care was defined as extreme-risk patients who died within 48 hours of an operation. The incidence of, and clinical factors associated with, futile surgery were identified. RESULTS: Of 94,350 emergency general surgery patients, 1.9% were extreme-risk. Among extreme-risk patients, 30-day mortality was 71.2%; 31.6% of extreme-risk patients died within 48 hours, representing futile care. Only 5.5% of extreme-risk patients were discharged home. Patients who were >80 years (odds ratio [OR] 6.25 vs 40-64; 95% confidence interval [CI], 4.51-8.66), septic (OR 4.63; 95% CI, 3.38-6.34), or had a dependent functional status (OR 2.50 vs independent; 95% CI, 1.83-3.43]) had higher odds of having a futile operation. CONCLUSION: A significant number of emergency general surgery operations were on extreme-risk patients who suffered early death, which may indicate futile care. Surgeons face numerous conflicting pressures when asked to perform potentially futile surgery. Additional research in the decision-making process in these cases is needed to understand why surgeons operate in such dire circumstances and whether they should.

Importance: Leading cancer hospitals have increasingly shared their brands with other hospitals through growing networks of affiliations. However, the brand of top-ranked cancer hospitals may evoke distinct reputations for safety and quality that do not extend to all hospitals within these networks. Objective: To assess perioperative mortality of Medicare beneficiaries after complex cancer surgery across hospitals participating in networks with top-ranked cancer hospitals. Design, Setting, and Participants: A cross-sectional study was performed of the Centers for Medicare & Medicaid Services 100% Medicare Provider and Analysis Review file from January 1, 2013, to December 31, 2016, for top-ranked cancer hospitals (as assessed by U.S. News and World Report) and affiliated hospitals that share their brand. Participants were 29â¯228 Medicare beneficiaries older than 65 years who underwent complex cancer surgery (lobectomy, esophagectomy, gastrectomy, colectomy, and pancreaticoduodenectomy [Whipple procedure]) between January 1, 2013, and October 1, 2016. Exposures: Undergoing complex cancer surgery at a top-ranked cancer hospital vs an affiliated hospital. Main Outcomes and Measures: Risk-adjusted 90-day mortality estimated using hierarchical logistic regression and comparison of the relative safety of hospitals within each cancer network estimated using standardized mortality ratios. Results: A total of 17â¯300 patients (59.2%; 8612 women and 8688 men; mean [SD] age, 74.7 [6.2] years) underwent complex cancer surgery at 59 top-ranked hospitals and 11â¯928 patients (40.8%; 6287 women and 5641 men; mean [SD] age, 76.2 [6.9] years) underwent complex cancer surgery at 343 affiliated hospitals. Overall, surgery performed at affiliated hospitals was associated with higher 90-day mortality (odds ratio, 1.40; 95% CI, 1.23-1.59; P < .001), with odds ratios that ranged from 1.32 (95% CI, 1.12-1.56; P = .001) for colectomy to 2.04 (95% CI, 1.41-2.95; P < .001) for gastrectomy. When the relative safety of each top-ranked cancer hospital was compared with its collective affiliates, the top-ranked hospital was safer than the affiliates in 41 of 49 studied networks (83.7%; 95% CI, 73.1%-93.3%). Conclusions and Relevance: The likelihood of surviving complex cancer surgery appears to be greater at top-ranked cancer hospitals compared with the affiliated hospitals that share their brand. Further investigation of performance across trusted cancer networks could enhance informed decision making for complex cancer care.

BACKGROUND: Brain metastases are a major cause of mortality in patients with small cell lung cancer (SCLC). Prophylactic cranial irradiation (PCI) may improve survival among patients that respond to chemotherapy. Less is known about the outcomes of PCI following surgical resection of SCLC. The purpose of this study was to determine if patients who underwent initial surgical resection of SCLC benefit from PCI. METHODS: Adult patients in the National Cancer Database (NCDB) who underwent complete resection for primary, non-metastatic SCLC between 2004 and 2015 were identified. Patients that received preoperative chemotherapy or who did not receive appropriate adjuvant chemotherapy were excluded. Patients were grouped by treatment with or without cranial radiation within 8 months of resection. Survival was estimated using Kaplan-Meier and Cox multivariable analysis, adjusting for patient and tumor characteristics. RESULTS: A total of 859 patients met inclusion criteria (202 received PCI and 657 did not). Kaplan-Meier analysis demonstrated that patients treated with PCI had significantly improved survival compared to no PCI (5-year survival 59% vs. 50%, logrank P=0.0038). Multivariable cox models confirmed a significantly decreased hazard of death for patients receiving PCI (HR: 0.70, 95% CI: 0.55-0.89, P=0.003). In subset analyses, PCI was associated with significantly improved survival for node positive patients, but not node negative patients. CONCLUSIONS: PCI is associated with increased survival for patients following surgical resection of SCLC. Patients with positive lymph nodes appear to benefit the most, while it remains unclear if patients with negative lymph nodes derive a benefit. Further study is warranted to clarify which subsets of patients should be treated with PCI.
RESUMEN
In recent years, analysis of registry data has defined clinically significant practice patterns and treatment strategies that optimize cancer care for thoracic surgery patients. These higher-order outcome studies rely on large patient cohorts that minimize the risk of selection bias and allow for a powered analysis that is not achievable with single- or multi-institutional data. This review uses recent study examples to highlight important contributions to our knowledge of thoracic surgery and describes how outcomes research using large data can address high impact clinical questions.
