Evaluation of nationwide trends in nodal sampling guideline adherence for gastric cancer: 2005-2017.
This study’s purpose was to evaluate trends in program-level disparities in adherence to gastric cancer nodal sampling guidelines. The cohort included 55,421 patients who underwent resection of gastric cancer from 2005 to 2017 identified in the National Cancer Database. Of that total 27,201 (49.1%) of patients met adherence criteria for lymph node sampling. Academic hospitals treated 44.4% of the total cohort. Overall, lymph node sampling criteria were met in 59.2% of patients treated at high-volume academic programs and 37.0% of patients treated at low-volume nonacademic programs. Adherence rates improved overall from 2005 to 2017 for both low-volume nonacademic programs (27.8% in 2005 to 50.1% in 2017) and high-volume academic programs (46.0% in 2005 to 69.8% in 2017).

Surgical versus non-surgical management for patients with malignant bowel obstruction (S1316): a pragmatic comparative effectiveness trial.
The purpose of this study was to compare surgical versus non-surgical management with the goal of determining the optimal approach for managing malignant bowel obstruction. From May 11, 2015, to April 27, 2020, 221 patients were enrolled, with 199 evaluable participants. The study found no variation between surgery and non-surgery for the primary outcome of good days: mean 42·6 days in the randomized surgery group, 43·9 days (29·5) in the randomized non-surgery group, 54·8 days (27·0) in the patient choice surgery group, and 52·7 days (30·7) in the patient choice non-surgery group. During their initial hospital stay, six participants died, five due to cancer progression and one due to malignant bowel obstruction treatment complications The most common grade 3-4 malignant bowel obstruction treatment complication was anemia.

Do age-based discontinuation recommendations influence cervical cancer screening rates? Evidence from the United States' Behavioral Risk Factor Surveillance System, 2016 and 2018.
The purpose of this study was to determine how the United States Preventive Services Task Force (USPSTF) recommendation of discontinuing routine cervical cancer screening for certain women after age 65 affects Papanicolaou (Pap) test rates among women at age 66 in the United States. The researchers utilized nationally representative 2016 and 2018 Behavioral Risk Factor Surveillance System (BRFSS) data for 226,031 women ages 56-76 to calculate changes in annual Pap test rates at age 66. Among women 66-76, 22.5% indicated they had received a Pap test within the past year. At age 66, annual Pap rates decreased by 5.9 percentage points (p.p.) off a pre-66 rate of 39 percent. The change differed by race/ethnicity, education, and marital status. Pap rates did not change discretely for non-Hispanic Black women but did change for women from other racial/ethnic groups. The decrease was larger for women who graduated college than for women without a college degree and for women who were never married than for women who were married/partnered or divorced/separated. The USPSTF recommendation to stop cervical cancer screening after the age of 65 resulted in a substantial decrease in the rate of Pap tests at age 66 but disparately affects women based on marital status, education and race.

Skin cancer screening: updated evidence report and systematic review for the US Preventive Services Task Force.
The purpose of this study was to investigate the advantages and potential risks of skin cancer screening to assist the decision-making of the US Preventive Services Task Force. The researchers utilized the data sources MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials, dated between June 1, 2015, and January 7, 2022. Two independent reviewers evaluated the articles and extracted pertinent data from studies of fair or good quality; the findings were summarized narratively. The primary outcomes and indicators were morbidity; mortality; stage, precursor lesions, or lesion thickness of skin cancer at detection; potential harms of screening. Twenty studies from 29 articles were included (N = 6,053,411). Direct evidence on the effectiveness of screening was obtained from 3 nonrandomized analyses of 2 population-based skin cancer screening initiatives in Germany (n = 1,791,615), indicating no significant reduction in melanoma mortality benefit at the population level over a period of 4 to 10 years of follow up activities. Six studies (n = 2,935,513) offered inconclusive evidence on the relationship between physician-conducted skin examination and lesion thickness or stage at diagnosis. Usual care vs. routine physician-conducted skin examination was not associated with increased detection of skin cancer or precursor lesions (5 studies) or stage at melanoma detection (3 studies). The correlation between physician-conducted skin examination and lesion thickness at detection was inconsistent (3 studies). Nine studies (n = 1 326 051) found a consistent positive association between more advanced stage at melanoma detection and increasing risk of melanoma-associated and all-cause mortality. Two studies (n = 232) found negligible enduring cosmetic or psychosocial harms related to screening.

Association between adherence to radiation therapy quality metrics and patient reported outcomes in prostate cancer.
Researchers evaluated the impact of compliance with nationally recognized radiation therapy quality measures on patient-reported health-related quality of life outcomes in the Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) population-based, prospective cohort study of men with localized prostate cancer. Eight quality measures were identified based on national guidelines. In multivariable analyses, no clinically significant associations were discovered between compliance with evaluated radiation therapy quality measures and patient-reported outcomes such as urinary irritation, urinary incontinence, bowel, sexual or hormonal function. The researchers concluded that further work would be needed to identify patient-centered quality measures of prostate cancer care.

The optimization of postoperative radiotherapy in de novo stage IV breast cancer: evidence from real-world data to personalize treatment decisions.
The purpose of this study was to investigate the survival benefit of radiotherapy in de novo stage IV breast cancer. Data were taken from the National Cancer DataBase on Stage IV breast cancer patients who received breast surgery and had survived 12 months after diagnosis. Radiotherapy was found to be associated with improved survival in patients with bone or lung metastasis but not patients with liver or brain metastasis. It was also associated with improved survival in patients with one or two metastatic sites but not three or more. Survival impact did not differ among subtypes. The authors concluded that these “real-world data” show that postoperative radiotherapy might improve overall survival for de novo Stage IV breast cancer with bone or lung metastasis, regardless of subtypes.

Using the framework for reporting adaptations and modifications-expanded (frame) to study adaptations in lung cancer screening delivery in the Veterans Health Administration: a cohort study.
The purpose of this study was to apply the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to study adaptations in lung cancer screening delivery processes in a Veterans Health Administration (VHA) Initiative. Between 2019 and 2021 the researchers prospectively administered semi-structured interviews with lung cancer screening program navigators at 10 Veterans Affairs Medical Centers (VAMCs). Baseline process maps were developed for each program, and each program navigator reviewed process maps in subsequent years 1 and 2. Researchers then identified, documented, and mapped adaptations in screening processes to the FRAME categories. 16 interviews were conducted across 10 VHA lung cancer screening programs, with 6 of these being operational, and of those 3 reported adaptations to their screening processes that were planned or in response to COVID-19. In year 2 all 10 programs were operational and eligible. Programs reported 14 adaptations in year 2. The adaptations identified were both planned and unplanned and often prompted by increased workload; 57% of year 2 adaptations were associated with the identification and eligibility of Veterans and 43% were associated with follow-up with Veterans for screening results. During the 2 years, adaptations associated with data management and patient tracking took place in 60% of programs to improve the data collection and tracking of Veterans in the screening process. The study concluded that adaptations took place predominantly in the categories of patient identification and communication of results due to increased workload.

Risk assessment, genetic counseling, and genetic testing for BRCA-related cancer in women: a systematic review to update the U.S. Preventive Services Task Force recommendation.
This systematic review was done in support of the U.S. Preventive Services Task Force (USPSTF) updated recommendation on the benefit and harms of risk assessment, genetic testing, and genetic counseling for BRCA-related cancer in women. A systematic review was done on literature from 2004 to July 30, 2013 from MEDLINE, PsycINFO, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Health Technology Assessment, Scopus, and reference lists. Data on the participants, study design, analysis, follow-up, and results was extracted and a second investigator confirmed key data. The studies were rated on study quality and applicability. The analysis found women with high-risk for breast cancer had decreased risk of breast cancer by 85% to 100% by having a mastectomy, and risk of mortality by 81% to 100% compared to women without surgery. There was also a lower risk of breast and ovarian cancer after having salpingo-oopherectomy surgery.
