Background
Many rectal cancer patients experience tumor downstaging and some are found to achieve a pathological complete response (pCR) after neoadjuvant chemoradiotherapy (nCRT). Previous data suggest that there is an association between the time interval from nCRT completion to surgery and tumor response rates, including pCR. However, these studies have been primarily from single institutions with small sample sizes. The aim of this study was to examine the relationship between a longer interval after nCRT and pCR in a nationally representative cohort of rectal cancer patients.
Study Design
Clinical stage II–III rectal cancer patients undergoing nCRT with a documented surgical resection were selected from the 2006 – 2011 National Cancer Data Base. Multivariable logistic regression analysis was used to assess the association between nCRT-surgery interval time (<6 weeks, 6–8 weeks, >8 weeks) and the odds of pCR. The relationship between nCRT-surgery interval, surgical morbidity, and tumor downstaging was also examined.
Results
Overall, 17,255 patients met the inclusion criteria. A nCRT-surgery interval time >8 weeks was associated with higher odds of pCR (OR=1.12, 95%CI=1.01–1.25) and tumor downstaging (OR=1.11, 95%CI =1.02–1.25). The longer time delay was also associated with lower odds of 30-day readmission (OR=0.82, 95%CI: 0.70–0.92).
Conclusions
A nCRT-surgery interval time >8 weeks results in increased odds of pCR with no evidence of associated increased surgical complications compared to 6–8 weeks. This data supports the implementation of a lengthened interval after nCRT to optimize the chances of pCR and perhaps add to the possibility of ultimate organ preservation (non-operative management).
Background
The rapid spread of COVID‐19 has placed tremendous strain on the American healthcare system. Few prior studies have evaluated the well‐being of or changes to training for American resident physicians during the COVID‐19 pandemic. We aim to study predictors of trainee well‐being and changes to clinical practice using an anonymous survey of American urology residents.
Methods
An anonymous, voluntary, 47‐question survey was sent to all ACGME‐accredited urology programmes in the United States. We executed a cross‐sectional analysis evaluating risk factors of perception of anxiety and depression both at work and home and educational outcomes. Multiple linear regressions models were used to estimate beta coefficients and 95% confidence intervals.
Results
Among ~1800 urology residents in the USA, 356 (20%) responded. Among these respondents, 24 had missing data leaving a sample size of 332. Important risk factors of mental health outcomes included perception of access to PPE, local COVID‐19 severity and perception of susceptible household members. Risk factors for declination of redeployment included current redeployment, having children and concerns regarding ability to reach case minimums. Risk factors for concern of achieving operative autonomy included cancellation of elective cases and higher level of training.
Conclusions
Several potential actions, which could be taken by urology residency programme directors and hospital administration, may optimise urology resident well‐being, morale, and education. These include advocating for adequate access to PPE, providing support at both the residency programme and institutional levels, instituting telehealth education programmes, and fostering a sense of shared responsibility of COVID‐19 patients.
Background:Given scarce data regarding the relationship among age, complications, and survival beyond the 30-day postoperative period for oncology patients in the United States, this study identified age-related differences in complications and the rate and cause of 1-year mortality following colon cancer surgery.Methods:The NY State Cancer Registry and Statewide Planning and Research Cooperative System identified stage I–III colon cancer resections (2004–2011). Multivariable logistic regression and survival analyses assessed the relationship among age (<65, 65–74, ⩾75), complications, 1-year survival, and cause of death.Results:Among 24 426 patients surviving >30 days, 1-year mortality was 8.5%. Older age groups had higher complication rates, and older age and complications were independently associated with 1-year mortality (P<0.0001). Increasing age was associated with a decrease in the proportion of deaths from colon cancer with a concomitant increase in the proportion of deaths from cardiovascular disease. Older age and sepsis were independently associated with higher risk of colon cancer-specific death (65–74: HR=1.59, 95% CI=1.26–2.00; ⩾75: HR=2.57, 95% CI=2.09–3.16; sepsis: HR=2.58, 95% CI=2.13–3.11) and cardiovascular disease-specific death (65–74: HR=3.72, 95% CI=2.29–6.05; ⩾75: HR=7.02, 95% CI=4.44–11.10; sepsis: HR=2.33, 95% CI=1.81–2.99).Conclusions:Older age and sepsis are associated with higher 1-year overall, cancer-specific, and cardiovascular-specific mortality, highlighting the importance of geriatric assessment, multidisciplinary care, and cardiovascular optimisation for older patients and those with infectious complications.
Preoperative CEA was an independent predictor of overall survival across all stages. The results support recommendations to include CEA levels as another high-risk feature that clinicians can use to counsel patients on adjuvant chemotherapy, especially for stage II patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
