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.

Type and case volume of health care facility influences survival and surgery selection in cases with early-stage non-small cell lung cancer.
With the expansion of non-small cell lung cancer (NSCLC) screening methods, the percentage of cases with early-stage NSCLC is anticipated to increase. Yet it remains unclear how the type and case volume of the health care facility at which treatment occurs may affect surgery selection and overall survival for cases with early-stage NSCLC. In this study, the investigators examine how type and case volume of health care facility influenced survival and surgery selection in cases with early-stage non-small cell lung cancer.

Association of discretionary hospital volume standards for high-risk cancer surgery with patient outcomes and access, 2005-2016.
Various clinical societies and patient advocacy organizations continue to encourage minimum volume standards at hospitals that perform certain high-risk operations. Although many clinicians and quality and safety experts believe this can improve outcomes, the extent to which hospitals have responded to these discretionary standards remains unclear. The purpose of this study was to evaluate the association between short-term clinical outcomes and hospitals' adherence to the Leapfrog Group's minimum volume standards for high-risk cancer surgery.

Patient-reported sexual quality of life after different types of radical prostatectomy and radiotherapy: analysis of a population-based prospective cohort.
This study compares the effects of different types of radical prostatectomy and radiotherapy on sexual function. A population-based cohort of 835 men with newly diagnosed prostate cancer from 2011 through 2013 was recruited in collaboration with the Rapid Case Ascertainment system of the North Carolina Central Cancer Registry. They were enrolled prior to treatment and followed retrospectively using the validated Prostate Cancer Symptom Indices (PCSI) instrument. The sexual function scores were compared among patients who received the following treatment types: external-beam RT (EBRT), EBRT with androgen deprivation therapy (ADT), brachytherapy, nerve-sparing radical prostatectomy (RP), and non-nerve-sparing RP. The cohort was surveyed at 24 months post-therapy, and RT alone was found to result in the best preservation of sexual function with brachytherapy, RT with ADT, and nerve-sparing RP yielding similar outcomes. Patients treated with non-nerve-sparing RP experienced the worst sexual function outcome.

Case sequence analysis of the robotic colorectal resection learning curve.
This study examined trends in the increasing rate of resection surgery for colorectal cancer using robots. It has a major learning curve so investigators wanted to see if complication rates went down as the technology become more common. The cohort included adults undergoing colorectal section from 2008 through 2016 from data in the New York Statewide Planning and Research Cooperative database. The number of procedures started at 76 cases in 2010 and increased to 702 cases in 2015. Findings were that major complications (myocardial infarction, pulmonary embolism, shock, and death) did not decrease but iatrogenic complications were reduced. The odds of prolonged length of stay also decreased over time.

Clinical outcomes and costs following unplanned excisions of soft tissue sarcomas in the elderly.
This study’s goal was to analyze the costs and outcomes of planned vs. unplanned soft tissue sarcoma (STS) excisions in the Medicare population. The authors analyzed 3913 surgical patients with STS >/=66 y old from 1992 to 2011 using the Surveillance, Epidemiology, and End Results-Medicare (SEER-Medicare) datafiles. Planned excision rates were classified from preoperative MRI or biopsy records. There was no difference in survival rates between planned vs. unplanned excisions. Planned excisions costs were higher than unplanned excision with the first resection contributing to the majority of costs.

Is breast-conserving therapy appropriate for male breast cancer patients? A national cancer database analysis.
The purpose of this study was to compare overall survival rates among male breast cancer patients who underwent breast-conserving therapy (BCT) versus mastectomy. A retrospective analysis identified 8445 stage I-II male breast cancer patients from the National Cancer Database and grouped them according to surgical and radiation therapy (RT). Most of the patients underwent total mastectomy, while 18.2% underwent BCT, 12.4% underwent total mastectomy with RT, and 8.2% underwent partial mastectomy alone. Partial mastectomy alone, total mastectomy alone, and total mastectomy with RT were associated with worse overall survival rates compared with BCT. The authors conclude that BCT is associated with greater survival, but the underlying mechanisms of this association warrant further study.

Call for improved design and reporting in soft tissue sarcoma studies: a systematic review and meta-analysis of chemotherapy and survival outcomes in resectable STS.
Researchers completed a meta-analysis of chemotherapy in localized STS, assessing OS, PFS, and local and distant recurrence. They found no benefit of chemotherapy over locoregional therapy alone for all-comers or site-specific STS. Recommendations to improve outcome reporting and quality indices are suggested.

Factors influencing prostate cancer treatment decisions for African American and white men.
This prospective, population-based cohort study examined some possible reasons for mortality outcome differences for prostate cancer between African American (AA) and white patients. A cohort of 1170 men with nonmetastatic prostate cancer were enrolled from 2011 to 2013 before treatment in North Carolina. Participants were asked to rate their aggressiveness of their cancer, and also the importance of 10 factors their treatment decision-making process. Among low-risk patients, there was no difference in perception of their cancer as “not very aggressive”. Among high-risk patients, 54% of AA patients considered their cancer to be “not very aggressive” while only 24% of white patients did. For AA patients, cost, treatment time, and recovery time were considered very important more than white patients.

Predictors of response outcomes for research recruitment through a central cancer registry: evidence from 17 recruitment efforts for population-based studies.
The authors conducted multivariable mixed-effects logistic regression to identify case and study characteristics associated with making contact with and obtaining cooperation of Utah cancer cases. They found that characteristics associated with lower odds of contact included Hispanic ethnicity, nonwhite race, and younger age at contact. Years since diagnosis was inversely associated with making contact. Increased odds of cooperation were associated with including a questionnaire, postage stamps, and incentives. They concluded that obtaining high response is challenging, but study features identified in this analysis support better results when recruiting through central cancer registries.

Lack of correlation between short- and long-term performance after lung cancer surgery.
In this study, the investigators examined correlation between measures of short-term and long-term performance for lung cancer surgery. The investigators concluded that avoidance of perioperative morbidity and mortality is an incomplete measure of performance in lung cancer surgery. They suggest that lung cancer surgery performance metrics should assess the safety of surgery and long-term survival.

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.

Practice patterns of primary EBRT with and without ADT in prostate cancer treatment.
This study investigated usage of external-beam radiation therapy (EBRT), with or without neoadjuvant androgen deprivation therapy (ADT), using data from a community-based prospective disease registry (CaPSURE). Data on 1337 men diagnosed between 1990 and 2014 with localized disease who received EBRT as primary treatment was compared. The authors conclude that use of ADT in conjunction with primary EBRT has increased in frequency and duration since 1990, and that men who received ADT have higher risk characteristics than those who receive EBRT alone.
