Increasing socioeconomically disadvantaged patients' engagement in breast cancer surgery decision-making through a shared decision-making intervention (A231701CD): protocol for a cluster randomised clinical trial.
This paper describes the protocol for a multisite randomized trial to test the impact of a newly developed decision aid to increase socioeconomically disadvantaged patients' engagement in breast cancer surgery decision-making. The study will be conducted through 10 surgical clinics within the National Cancer Institute Community Oncology Research Program (NCORP). A stepped-wedge design with clinics will be randomized to the time of transition from usual care to the decision aid arm. Study participants will be female, aged ≥18 years, with newly diagnosed stage 0-III breast cancer who are planning breast surgery. Data collection will include a baseline surgeon survey, baseline patient survey, audio-recording of the surgeon-patient consultation, a follow-up patient survey and medical record data review. A subset of patients, surgeons, and clinic stakeholders will participate in interviews and focus groups.

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.

Trends in rural-urban disparities among surgical specialties treating cancer, 2004-2017.
The purpose of this study was to assess trends over time in rural and urban disparities in the supply of surgeons treating patients with cancer. The researchers utilized the Area Health Resource File to conduct a retrospective observational study of medical workforce changes from 2004-2017. The study found that the density of surgical specialists in rural areas declined from 16 to 14 per 100,000 population and in urban areas from 33 to 31 per 100,000 population for a rural-urban disparity increase of 8%. The percentage increase in the supply disparity between the rural and urban workforce was largest for colorectal surgeons (66%) and general surgeons (72%). The study concluded that temporal changes in the rural-urban physician workforce depend on community factors, region, and area of specialization.

Trends in surgical treatment of early-stage breast cancer reveal decreasing mastectomy use between 2003 and 2016 by age, race, and rurality.
The authors sought to examine trends in the surgical treatment of breast cancer by age, rurality, and among Black women in a populous, racially diverse, state in the Southeastern United States of America. Using data from the North Carolina Central Cancer Registry, they found declining mastectomy rates in the early 2000s in a Southern US state with a racially and geographically diverse population. These decreasing trends were consistent among key subgroups affected by cancer inequities, including Black and White rural women.

Association of dual Medicare and Medicaid eligibility with outcomes and spending for cancer surgery in high-quality hospitals.
The purpose of this study was to assess whether treatment at high-quality hospitals mitigates dual-eligibility-associated disparities in outcomes and spending for cancer surgery. Medicare beneficiaries 65 years or older who underwent colectomy, rectal resection, lung resection, or pancreatectomy were evaluated. The findings indicate that, even among the highest-quality hospitals, dual-eligibility patients had poorer outcomes and higher spending. Dually eligible patients were more likely to be discharged to a facility and thus incurred higher post-acute care costs. Although treatment at high-quality hospitals is associated with reduced differences in outcomes, dual-eligibility patients remain at high risk for adverse post-operative outcomes as well as increased readmissions and post-acute care use.

Validity of breast cancer surgery treatment information in a state-based cancer registry.
Surgery is an important part of early stage breast cancer treatment that affects overall survival. Statewide cancer registries contain data on first course of cancer treatment for all patients diagnosed with cancer but the accuracy of these data are uncertain. In this study, the authors examined validity of breast cancer surgery treatment information in a state-based cancer registry.

Endometrial sampling for preoperative diagnosis of uterine leiomyosarcoma.
This retrospective cohort study examined the effectiveness of endometrial sampling for preoperative detection of uterine leiomyosarcoma in women undergoing hysterectomy, identified factors associated with missed diagnosis, and compared the outcomes of patients who had a preoperative diagnosis with those patients who had a missed diagnosis. A total of 79 patients with uterine leiomyosarcoma were included in the study. Of those patients, 46 (58.2%) were diagnosed preoperatively and 33 postoperatively. The groups were similar in age, race/ethnicity, bleeding symptoms, and comorbidities. Women who had endometrial sampling performed with hysteroscopy had a higher likelihood of preoperative diagnosis. Patients with localized stage (vs distant stage) or tumor size >11 cm were less likely to be diagnosed preoperatively.

Reevaluating the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer.
This study reevaluated the evidence for intensive postoperative extracolonic surveillance for nonmetastatic colorectal cancer. The authors looked at the FACS, GILDA, and COLOFOL trials and used a model to predict the large-sample mortality reduction expected for each trial and the implied statistical power. An investigation was done of a potential recurrence imbalance in the FACS trial. The model predicted a mortality reduction of ≤5% and power of <10% for all 3 trials. The FACS recurrence imbalance most likely led to a large relative bias (>2.5) in the hazard ratio for overall survival favoring control. After adjustment, both COLOFOL and FACS results were consistent with model predictions. A 2.6 and 3.6 month increase in life expectancy is predicted comparing intensive extracolonic surveillance-routine computed tomography scans and carcinoembryonic antigen assays with 1 computed tomography scan at 12 months or no surveillance, respectively. A larger trial that would randomize at least 200 to 300 patients is needed, but is not feasible at this time. The authors concluded recent trial results do not warrant de novo skepticism or metastasectomy nor targeted extracolonic surveillance.

Statewide episode spending variation of mastectomy for breast cancer.
The purpose of this study was to characterize variations in episode spending related to volume and complication rates for mastectomy. A secondary study aim was to identify patient- and facility-level determinants of variation. The researchers assessed mean spending for 7,342 patients undergoing mastectomy at 74 facilities across Michigan state. The study found that mean 30-day spending by facility ranged from $11,129 to $20,830 and ninety-day spending ranged from $17,303 to $31,060. Patient-level factors associated with greater spending included bilateral surgery, simultaneous breast reconstruction, length of stay, and readmission. The researchers concluded that Michigan hospitals have considerable variation in mastectomy spending, and that reducing the frequency of bilateral surgery and length of stay may increase value, without risking patient safety or oncologic outcomes.
