Association between power morcellation and mortality in women with unexpected uterine cancer undergoing hysterectomy or myomectomy.
Despite concerns that power morcellation may adversely affect prognosis of patients with occult uterine cancer, empirical evidence has been limited and inconclusive. In this study, the investigators aimed to determine whether uncontained power morcellation at the time of hysterectomy or myomectomy was associated with increased mortality risk in women with occult uterine cancer.

Centralization of high-risk cancer surgery within existing hospital systems.
Centralization is often proposed as a strategy to improve the quality of certain high-risk health care services. In this study, the investigators evaluated the extent to which existing hospital systems centralize high-risk cancer surgery and whether centralization is associated with short-term clinical outcomes. The investigators concluded that greater centralization of complex cancer surgery within existing hospital systems was associated with better outcomes.

Incorporation of urinary prostate cancer antigen 3 and TMPRSS2:ERG into Prostate Cancer Prevention Trial Risk Calculator.
The objective of this study was to determine whether the incorporation of two urinary markers, prostate cancer antigen 3 (PCA3) and TMPRSS2:ERG (T2:ERG), into the Prostate Cancer Prevention Trial Risk Calculator (PCPTRC) tool improves its discrimination, accuracy, and clinical net benefit. A Bayesian modeling approach was used to combine data where the markers were measured in a Michigan cohort with the PCPTRC as prior probabilities to create an updated PCPTRC; this update was compared to the existing PCPTRC in terms of discrimination, calibration, and decision curve analysis. Net benefit was improved for the updated PCPTRC, but calibration was not. The authors note that, the updated PCPTRC is limited since it was based on two separate cohorts, and further validation is required. The updated tool is available online.

Association between androgen deprivation therapy use and diagnosis of dementia in men with prostate cancer.
The purpose of this study was to analyze the association between androgen deprivation therapy (ADT) exposure and diagnosis of Alzheimer disease or dementia among elderly men with prostate cancer. Results showed that, among elderly patients with prostate cancer, ADT exposure was associated with subsequent diagnosis of Alzheimer disease or dementia over a follow-up period of at least 10 years.

Risk of unexpected uterine cancer in women undergoing myomectomy: a population-based study.
Data on the risk of unexpected uterine cancer specifically for women undergoing myomectomy are limited, as prior research has centered on hysterectomies (surgical removal of the uterus). In this correspondence, the authors discuss how they addressed this important gap using a large population-based sample.

Prevalence, characteristics, and risk factors of occult uterine cancer in presumed benign hysterectomy.
The purpose of this study was to examine the prevalence of occult uterine cancer in a large population-based sample of women undergoing hysterectomy for presumed benign indications and to identify associated risk factors. Results showed that, in women undergoing hysterectomy for presumed benign indications, 0.96% had unexpected uterine cancer, with the risk being significantly associated with race/ethnicity, obesity, comorbidity, and personal history of malignancy.

Validation of the breast cancer surveillance consortium model of breast cancer risk.
This study evaluated the breast cancer surveillance consortium (BCSC) model of breast cancer risk. The accuracy of the model was assessed using a racially diverse population followed for up to 10 years. An independent cohort of 252,997 women in the Chicago area was used to validate the model. The model was found to be well-calibrated, but underestimated the incidence of invasive breast cancer in younger women and in women with low mammographic density.

Population-based assessment of the association between magnetic resonance imaging background parenchymal enhancement and future primary breast cancer risk.
The purpose of this study was to evaluate comparative associations of breast magnetic resonance imaging (MRI) background parenchymal enhancement (BPE) and mammographic breast density with subsequent breast cancer risk. The investigators concluded that BPE was associated with future invasive breast cancer risk independent of breast density. They suggest that BPE should be considered for risk prediction models for women undergoing breast MRI.

Psychosocial risks are independently associated with cancer surgery outcomes in medically comorbid patients.
The purpose of this prospective observational study was to assess the association of preoperative psychosocial risk factors and 30-day complications following cancer surgery. The investigators demonstrated a more than threefold odds of a complication in medically comorbid patients with multiple psychosocial risks. They suggest that their findings support the use of psychosocial risks in preoperative assessment and consideration for inclusion in preoperative optimization efforts.

Contributions of traditional and HIV-related risk factors on non-AIDS-defining cancer, myocardial infarction, and end-stage liver and renal diseases in adults with HIV in the USA and Canada: a collaboration of cohort studies.
Adults with HIV have an increased burden of non-AIDS-defining cancers, myocardial infarction, end-stage liver disease, and end-stage renal disease. The objective of this study was to estimate the population attributable fractions (PAFs) of preventable or modifiable HIV-related and traditional risk factors for non-AIDS-defining cancers, myocardial infarction, end-stage liver disease, and end-stage renal disease outcomes.
