Postdischarge prophylactic antibiotics following mastectomy with and without breast reconstruction.
The authors investigated factors associated with post-discharge prophylactic antibiotic use after mastectomy with and without immediate reconstruction and the impact on surgical-site infection (SSI). They found that anti-methicillin-sensitive Staphylococcus aureus antibiotics were associated with decreased risk of SSI for patients who had mastectomy only and those who had mastectomy with immediate reconstruction. They concluded that the high numbers needed to treat suggest that potential benefits of post-discharge antibiotics should be weighed against potential harms associated with antibiotic overuse.

The influence of practice structure on urologists' treatment of men with low-risk prostate cancer.
Researchers examined the influence of type of practice structure, and by implication the financial incentives associated with each structure, on treatment received among men newly diagnosed with low-risk prostate cancer. They found that physician practice structure attributes were significantly associated with type of treatment received but few studies controlled for such factors. Their findings - coupled with the observation that urologist practice structure shifted substantially over this time period due to mergers of small urology groups - provided one explanation for the limited uptake of active surveillance among men with low-risk disease in the US.

Physician specialties involved in thyroid cancer diagnosis and treatment: implications for improving health care disparities.
The authors sought to characterize providers involved in diagnosing and treating thyroid cancer. Patients with differentiated thyroid cancer from the Georgia and Los Angeles County Surveillance, Epidemiology and End Results registries were surveyed. The authors found that, among thyroid cancer patients, 40.6% reported being informed of their diagnosis by their surgeon, 37.9% by their endocrinologist, and 13.5% by their primary care physician (PCP). The researchers concluded that PCPs were involved in thyroid cancer diagnosis and treatment, and their involvement was greater among older patients and patients of minority race/ethnicity.

Has hypofractionated whole-breast radiation therapy become the standard of care in the United States? An updated report from National Cancer Database.
This study examined trends in the use of hypofractionated whole-breast irradiation (HF-WBI) over time in the United States and factors related to its adoption for patients undergoing a lumpectomy from 2004 to 2016. Lumpectomy patients in the National Cancer Database were identified, with 688,079 early-stage invasive breast cancer patients, and 248,218 patients diagnosed with ductal carcinoma in situ. Among invasive cancer patients, HB-WBI use increased from 0.7% in 2004 to 38.1% in 2016. Among ductal carcinoma in situ patients, HB-WBI use increased significantly from 0.42% in 2004 to 34.3% in 2016. Factors associated with HB-WBI use included age, geographic location, race/ethnicity, tumor stage, grade, treating facility type, and volume.

US trends in opioid access among patients with poor prognosis cancer near the end-of-life.
This study looked at trends in opioid prescriptions for cancer patients near the end-of-life (EOL) defined as the 30 days before death or hospice enrollment. The authors looked at Medicare part D data from 2007 to 2017 for 270,632 Medicare fee-for-service decedents with poor prognosis cancers. During that time, the proportion of decedents with poor prognosis cancers receiving 1 or greater opioid prescriptions near EOL declined 15.5% and the proportion receiving 1 or greater long-acting opioid prescriptions declined 36.5% to 18.1%. The mean daily dose fell from 24.5%, from 85.6 morphine milligram equivalents per day (MMED) to 64.6. The total amount of opioids prescribed fell from 1,075 morphine milligram equivalents per decedent to 666 morphine milligram equivalents per decedents. At the same time, the proportion of patients with pain-related ED visits increase 50.8% from 13.2% to 19.9%.

Urology workforce changes and implications for prostate cancer care among Medicare enrollees.
The purpose of this study was to characterize national trends in urologist workforce, practice organization, and management of incident prostate cancer. The investigators characterized shifts in urologist membership from smaller, independent groups to larger, multispecialty or hospital-owned practices. They indicated that this trend coincided with higher utilization of observation and surgical treatment for prostate cancer.

Surgeons' attitudes on total thyroidectomy vs lobectomy for management of papillary thyroid microcarcinoma.
The incidence of papillary thyroid cancer has increased in the past 25 years without a clear increase in thyroid cancer deaths. Given these findings, there has been a shift toward recommending conservative surgical options, with current management guidelines favoring lobectomy, especially for patients with papillary thyroid microcarcinoma. The aim of this study was to identify surgeons’ attitudes regarding surgical management of microcarcinomas with the hypothesis that surgeons consider other factors, in addition to tumor size, when selecting a surgical procedure.

Multilevel factors associated with more intensive use of radioactive iodine for low-risk thyroid cancer.
The use of radioactive iodine (RAI) for low-risk thyroid cancer is common, and variation in its use exists, despite the lack of benefit for low-risk disease and potential harms and costs. The objective of this study was to simultaneously assess patient- and physician-level factors associated with patient-reported receipt of RAI for low-risk thyroid cancer. The investigators concluded that physician perspectives and attitudes about using RAI, as well as patient volume, influenced RAI use for low-risk thyroid cancer.

Trends in breast cancer treatment de-implementation in older patients with hormone receptor-positive breast cancer: a mixed methods study.
Guidelines allow for the omission of sentinel lymph node biopsy (SLNB) and post-lumpectomy radiotherapy in women >/= 70 years of age with hormone receptor-positive (HR +) breast cancer. Despite this, national data suggest these procedures have not been widely de-implemented. The objectives of this study were to evaluate trends in SLNB and post-lumpectomy radiotherapy utilization in patients who were eligible for omission and evaluate patient preferences as a target for de-implementation of low-value care.

Opioid prescribing exceeds consumption following common surgical oncology procedures.
Researchers aimed to compare opioid prescribing to opioid consumption for common surgical oncology procedures. They found that the median quantity of opioid prescribed was significantly larger than consumed following breast biopsy, lumpectomy, and mastectomy or wide local excision. The majority of patients reported receiving education on taking opioids, but only 27% received instructions on proper disposal; 82% of prescriptions filled resulted in unused opioids, and only 11% of these patients safely disposed of them. They concluded that their study demonstrated that opioid prescribing exceeds consumption following common surgical oncology procedures, thus indicating the potential for reductions in prescribing.
