Impact of smoking on perioperative outcomes after major surgery
To investigate the impact of smoking on perioperative outcomes in patients undergoing one of the 16 major cardiovascular, orthopedic, or oncologic surgical procedures. We relied on the American College of Surgeons National Surgical Quality Improvement Program database (2005 to 2011). Procedure-specific multivariable logistic regression models assessed the association between smoking status (non, former, or current smokers) and risk of 30-day morbidity and mortality. Overall, 141,802 patients were identified. A total of 12.5%, 14.6%, and 14.9% of non, former, and current smokers, respectively, experienced at least one complication (P < .001). In multivariable models, current smokers had higher odds of overall, pulmonary, wound, and septic/shock complications following most cardiovascular and oncologic surgeries compared with nonsmokers. The odds of experiencing such adverse outcomes were significantly lower in former smokers compared with current smokers, but still higher compared with nonsmokers. The effect of smoking on perioperative outcomes is procedure dependent. Current and, even though mitigated, former smoking negatively influence outcomes following cardiovascular or oncologic procedures. Patients undergoing major procedures should be encouraged to discontinue tobacco smoking to achieve optimal procedural outcomes. •The impact of smoking on perioperative outcomes is procedure dependent.•Current smoking especially negatively influences outcomes following cardiovascular or oncologic procedures.•Former smokers had less adverse outcomes compared with current smokers, but still more compared with nonsmokers.•Patients undergoing major procedures should be encouraged to discontinue tobacco smoking to achieve optimal procedural outcomes.
PRState: Incorporating genetic ancestry in prostate cancer risk scores for men of African ancestry
Background Prostate cancer (PrCa) is one of the most genetically driven solid cancers with heritability estimates as high as 57%. Men of African ancestry are at an increased risk of PrCa; however, current polygenic risk score (PRS) models are based on European ancestry groups and may not be broadly applicable. The objective of this study was to construct an African ancestry-specific PrCa PRS (PRState) and evaluate its performance. Methods African ancestry group of 4,533 individuals in ELLIPSE consortium was used for discovery of African ancestry-specific PrCa SNPs. PRState was constructed as weighted sum of genotypes and effect sizes from genome-wide association study (GWAS) of PrCa in African ancestry group. Performance was evaluated using ROC-AUC analysis. Results We identified African ancestry-specific PrCa risk loci on chromosomes 3, 8, and 11 and constructed a polygenic risk score (PRS) from 10 African ancestry-specific PrCa risk SNPs, achieving an AUC of 0.61 [0.60–0.63] and 0.65 [0.64–0.67], when combined with age and family history. Performance dropped significantly when using ancestry-mismatched PRS models but remained comparable when using trans-ancestry models. Importantly, we validated the PRState score in the Million Veteran Program (MVP), demonstrating improved prediction of PrCa and metastatic PrCa in individuals of African ancestry. Conclusions African ancestry-specific PRState improves PrCa prediction in African ancestry groups in ELLIPSE consortium and MVP. This study underscores the need for inclusion of individuals of African ancestry in gene variant discovery to optimize PRSs and identifies African ancestry-specific variants for use in future studies.
Effect of Preoperative Angina Pectoris on Cardiac Outcomes in Patients With Previous Myocardial Infarction Undergoing Major Noncardiac Surgery (Data from ACS-NSQIP)
The impact of preoperative stable angina pectoris on postoperative cardiovascular outcomes in patients with previous myocardial infarction (MI) who underwent major noncardiac surgery is not well studied. We studied patients with previous MI who underwent elective major noncardiac surgeries within the American College of Surgeons–National Surgical Quality Improvement Program (2005 to 2011). Primary outcome was occurrence of an adverse cardiac event (MI and/or cardiac arrest). Multivariable logistic regression models evaluated the impact of stable angina on outcomes. Of 1,568 patients (median age 70 years; 35% women) with previous MI who underwent major noncardiac surgery, 5.5% had postoperative MI and/or cardiac arrest. Patients with history of preoperative angina had significantly greater incidence of primary outcome compared to those without anginal symptoms (8.4% vs 5%, p = 0.035). In secondary outcomes, reintervention rates (22.5% vs 11%, p <0.001) and length of stay (median 6-days vs 5-days; p <0.001) were also higher in patients with preoperative angina. In multivariable analyses, preoperative angina was a significant predictor for postoperative MI (odds ratio 2.49 [1.20 to 5.58]) and reintervention (odds ratio 2.40 [1.44 to 3.82]). In conclusion, our study indicates that preoperative angina is an independent predictor for adverse outcomes in patients with previous MI who underwent major noncardiac surgery, and cautions against overreliance on predictive tools, for example, the Revised Cardiac Risk Index, in these patients, which does not treat stable angina and previous MI as independent risk factors during risk prognostication.
The Effect of Body Mass Index on Perioperative Outcomes After Major Surgery: Results from the National Surgical Quality Improvement Program (ACS-NSQIP) 2005–2011
Background Obesity is associated with poor surgical outcomes and disparity in access-to-care. There is a lack of quality data on the effect of body mass index (BMI) on perioperative outcomes. Accordingly, we sought to determine the procedure specific, independent-effect of BMI on 30-day perioperative outcomes in patients undergoing major surgery. Methods Participants included individuals undergoing one of 16 major surgery (cardiovascular, orthopedic, oncologic; n  = 141,802) recorded in the ACS-NSQIP (2005–2011). Outcomes evaluated included complications, blood transfusion, length-of-stay (LOS), re-intervention, readmission, and perioperative mortality. Multivariable-regression models assessed the independent-effect of BMI on outcomes. Results Nearly, 74  % of patients had a BMI disturbance; the majority being overweight (35.3  %) or obese (29.8  %). Morbidly obese patients constituted a small but significant proportion of the patients (5.7 %; n  = 8067). In adjusted-analyses, morbidly obese patients had significantly increased odds of wound complications in 15 of the examined procedures, of renal complications after 6-procedures, of thromboembolism after 5-procedures, of pulmonary, septic and UTI complications after 2-procedures, and of cardiovascular complications after CABG. Conversely, obese/overweight patients, except for increased odds of wound complications after select procedures, had significantly decreased odds of perioperative mortality, prolonged-LOS and blood transfusion relative to normal BMI patients after 4, 8, and 9 of the examined procedures. Conclusions The prevalence of BMI derangements in surgical patients is high. The effect of BMI on outcomes is procedure specific. Patients with BMI between 18.5 and 40-kg/m 2 at time of surgery fare equally well with regard to complications and mortality. However, morbidly obese patients are at-risk for postsurgical complications and targeted preoperative-optimization may improve outcomes and attenuate disparity in access-to-care.
Racial Disparities in Operative Outcomes After Major Cancer Surgery in the United States
Background Numerous studies have recorded racial disparities in access to care for major cancers. We investigate contemporary national disparities in the quality of perioperative surgical oncological care using a nationally representative sample of American patients and hypothesize that disparities in the quality of surgical oncological care also exists. Methods A retrospective, serial, and cross-sectional analysis of a nationally representative cohort of 3,024,927 patients, undergoing major surgical oncological procedures (colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, pneumonectomy, pancreatectomy, and prostatectomy), between 1999 and 2009. Results After controlling for multiple factors (including socioeconomic status), Black patients undergoing major surgical oncological procedures were more likely to experience postoperative complications (OR: 1.24; p  < 0.001), in-hospital mortality (OR: 1.24; p  < 0.001), homologous blood transfusions (OR: 1.52; p  < 0.001), and prolonged hospital stay (OR: 1.53; p  < 0.001). Specifically, Black patients have higher rates of vascular (OR: 1.24; p  < 0.001), wound (OR: 1.10; p  = 0.004), gastrointestinal (OR: 1.38; p  < 0.001), and infectious complications (OR: 1.29; p  < 0.001). Disparities in operative outcomes were particularly remarkable for Black patients undergoing colectomy, prostatectomy, and hysterectomy. Importantly, substantial attenuation of racial disparities was noted for radical cystectomy, lung resection, and pancreatectomy relative to earlier reports. Finally, Hispanic patients experienced no disparities relative to White patients in terms of in-hospital mortality or overall postoperative complications for any of the eight procedures studied. Conclusions Considerable racial disparities in operative outcomes exist in the United States for Black patients undergoing major surgical oncological procedures. These findings should direct future health policy efforts in the allocation of resources for the amelioration of persistent disparities in specific procedures.
Pneumonia after Major Cancer Surgery: Temporal Trends and Patterns of Care
Rationale. Pneumonia is a leading cause of postoperative complication. Objective. To examine trends, factors, and mortality of postoperative pneumonia following major cancer surgery (MCS). Methods. From 1999 to 2009, patients undergoing major forms of MCS were identified using the Nationwide Inpatient Sample (NIS), a Healthcare Cost and Utilization Project (HCUP) subset, resulting in weighted 2,508,916 patients. Measurements. Determinants were examined using logistic regression analysis adjusted for clustering using generalized estimating equations. Results. From 1999 to 2009, 87,867 patients experienced pneumonia following MCS and prevalence increased by 29.7%. The estimated annual percent change (EAPC) of mortality after MCS was −2.4% (95% CI: −2.9 to −2.0, P<0.001); the EAPC of mortality associated with pneumonia after MCS was −2.2% (95% CI: −3.6 to 0.9, P=0.01). Characteristics associated with higher odds of pneumonia included older age, male, comorbidities, nonprivate insurance, lower income, hospital volume, urban, Northeast region, and nonteaching status. Pneumonia conferred a 6.3-fold higher odd of mortality. Conclusions. Increasing prevalence of pneumonia after MCS, associated with stable mortality rates, may result from either increased diagnosis or more stringent coding. We identified characteristics associated with pneumonia after MCS which could help identify at-risk patients in order to reduce pneumonia after MCS, as it greatly increases the odds of mortality.
Role of robot-assisted radical prostatectomy in the management of high-risk prostate cancer
We aimed to evaluate the role of robot-assisted radical prostatectomy (RARP) in the management of high-risk prostate cancer (PCa), with a focus on oncological, functional and perioperative outcomes. Further, we also aimed to briefly describe our novel modification to conventional RARP that allows immediate organ retrieval and examination for intra-operative surgical margin assessment. A literature search of PubMed was performed for articles on the management of high-risk PCa. Papers written in English and concerning clinical outcomes following RARP for locally advanced and high-risk PCa were selected. Outcomes data from our own center were also included. A total of 10 contemporary series were evaluated. Biopsy Gleason score ≥ 8 was the most common cause for classification of patients into the high-risk PCa group. Biochemical failure rate, in the few series that looked at long-term follow-up, varied from 9% to 26% at 1 year. The positive surgical margin rate varied from 12% to 53.3%. Urinary continence rates varied from 78% to 92% at 1 year. The overall complication rates varied from 2.4% to 30%, with anastomotic leak and lymphocele being the most common complications. Long-term data on oncological control following RARP in high-risk patients is lacking. Short-term oncological outcomes and functional outcomes are equivalent to open radical prostatectomy (RP). Safety outcomes are better in patients undergoing RARP when compared with open RP. Improved tools for predicting the presence of organ-confined disease (OCD) are available. High-risk patients with OCD would be ideal candidates for RARP and would benefit most from surgery alone.
Determinants of cancer screening in Asian-Americans
Purpose Recent data suggest that Asian-Americans (AsAs) are more likely to present with advanced disease when diagnosed with cancer. We sought to determine whether AsAs are under-utilizing recommended cancer screening. Methods Cross-sectional analysis of the 2012 Behavioral Risk Factor Surveillance System comprising of AsAs and non-Hispanic White (NHW) community-dwelling individuals (English and Spanish speaking) eligible for colorectal, breast, cervical, or prostate cancer screening according to the United States Preventive Services Task Force recommendations. Age, education and income level, residence location, marital status, health insurance, regular access to healthcare provider, and screening were extracted. Complex samples logistic regression models quantified the effect of race on odds of undergoing appropriate screening. Data were analyzed in 2015. Results Weighted samples of 63.3, 33.3, 47.9, and 30.3 million individuals eligible for colorectal, breast, cervical, and prostate cancer screening identified, respectively. In general, AsAs were more educated, more often married, had higher levels of income, and lived in urban/suburban residencies as compared to NHWs (all p  < 0.05). In multivariable analyses, AsAs had lower odds of undergoing colorectal (odds ratio [OR] 0.78, 95 % confidence interval [CI] 0.63–0.96), cervical (OR 0.45, 95 % CI 0.36–0.55), and prostate cancer (OR 0.55, 95 % CI 0.39–0.78) screening and similar odds of undergoing breast cancer (OR 1.29, 95 % CI 0.92–1.82) screening as compared to NHWs. Conclusions AsAs are less likely to undergo appropriate screening for colorectal, cervical, and prostate cancer. Contributing reasons include limitations in healthcare access, differing cultural beliefs on cancer screening and treatment, and potential physician biases. Interventions such as increasing healthcare access and literacy may improve screening rates.
Prostate cancer navigation: initial experience and association with time to care
ObjectiveTo evaluate factors associated with use of patient navigation in a prostate cancer population and identify whether navigation is associated with prolonged time to care. Cancer patient navigation has been shown to improve access to cancer screening, diagnosis, and treatment, but little is known about patient navigation in prostate cancer care.MethodsAll men diagnosed with localized prostate cancer between 2009 and 2015 were abstracted from the MaineHealth multi-specialty tumor registry. Regression analyses controlling for patient-, disease-, and system-level factors evaluated characteristics associated with navigation utilization. The association between navigation utilization, barriers to care, and longer time to treatment was assessed with Cox proportional hazards regression.ResultsOf the patient population (n = 1587), 85% of men were navigated. Navigation use was associated with earlier year of diagnosis, treatment by a high-volume urologist, and lower risk disease (p < 0.05). Treatment delay was associated with low-risk disease (vs: intermediate OR 0.62, 95% CI 0.46–0.85 and high OR 0.16, 95% CI 0.1–0.25) and receipt of navigation services (OR 1.65, 95% CI 1.12–2.45) but not distance to care, insurance, or treatment choice.ConclusionsWe observed that patients with low-risk prostate cancer were more likely to utilize navigation, but traditional barriers to care were not associated with utilization. Navigation was associated with longer time to treatment, which likely reflects clinically appropriate delays associated with greater shared decision making. Time to treatment may not be the ideal metric for evaluating navigation in prostate cancer; shared decision making, patient satisfaction, and psychosocial outcomes may be more appropriate.
Radiotherapy might improve survival, even in the oldest men
In a recent study, men ≥80 years who received external beam radiotherapy (EBRT) for prostate cancer lived longer than those who were observed. Greatest benefits were reported in men with moderate or aggressive disease, and those with few comorbidities. The study also emphasizes the large proportion of men who went untreated after diagnosis.
