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.

Development and validation of a bayesian network method to detect external beam radiation therapy physician order errors.
This study investigated using a Bayesian network (BN)-based method to detect physician order errors in external beam radiation therapy. The authors extracted data from 4331 total external beam radiation orders written from 2008 to 2017 at their institution of origin. The cohort was divided into 3 groups: single prescription, concurrent boost, and sequential boost. True-positive (TPR) and false-positive (FPR) rates were determined. The investigators saw good results using the BN method.

Impact of oncology drug shortages on chemotherapy treatment.
The investigators examined outpatient chemotherapy use during shortage periods relative to the months before and after a shortage for newly diagnosed patients. For most drugs, little impact of shortages on either the fraction of patients receiving that drug or the quantity provided was found. The investigators discussed potential explanations for these counterintuitive findings, including potential limitations of current drug shortage reporting methods.

Automated closed- and open-loop validation of knowledge-based planning routines across multiple disease sites.
This study examined the use of knowledge-based planning (KBP) clinical implementation for treatment across multiple disease sites using volumetric modulated arc therapy. Researchers identified patients with prostate, lung, and head and neck cancers who were treated in the year right before their clinic’s broad adoption of RapidPlan. Statistically significant organ dose-volume histogram improvements were observed in the KBP cohort compared to manual planning.

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.

Evaluating surveillance patterns after chemoradiation-only compared with conventional management for older patients with rectal cancer.
This study examined surveillance patterns for elderly patients who were treated only with chemoradiation (CR) as opposed to traditional treatment (chemoradiation and protectomy). In the cohort study, a total of 2,482 individuals met the inclusion criteria, with 21% receiving CR-only treatment, and 79% had conventional treatment. In comparison to patients who had traditional treatment, patients with CR-only treatment had far less follow-up during the first 2 years post-treatment. Adherence to guideline-recommended surveillance was poor for all Medicare patients, but especially for CR-only treated patients.

First, do no harm: rethinking routine diversion in sphincter-preserving rectal cancer resection.
The authors hypothesized that routine temporary diversion is not associated with decreased rates of leak or reintervention in cancer patients at large undergoing sphincter-sparing procedures. Using HCUP data from the Florida State Inpatient Database, they found no association between diversion and anastomotic leak. However, temporary diversion was associated with increased incidence of nonelective reinterventions, readmissions, and higher costs. They recommended additional study to identify which patients would benefit most from diversion.

Chemotherapy costs and 21-gene recurrence score genomic testing among Medicare beneficiaries with early-stage breast cancer, 2005 to 2011.
This study examined whether associations between 21-gene recurrence score (RS) genomic testing and lower costs among patients with early-stage, estrogen receptor-positive breast cancer were observable in real-world data from the Medicare population. The investigators found that RS testing was associated with lower overall and chemotherapy-related costs in patients with high-risk disease, consistent with lower chemotherapy use among these patients. Higher overall costs for patients with intermediate-risk and low-risk disease were driven largely by non-treatment-related costs.

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.

Trends in outcomes after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.
The goal of this study was to describe temporal trends in clinical outcomes among patients undergoing cytoreductive surgery or hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). Operative time, postoperative morbidity, and length of stay after CRS/HIPEC were observed to improve over the study period. Careful patient selection may result in favorable outcomes for select patients undergoing CRS/HIPEC.
