Background: Racial-ethnic differences in breast cancer treatment in the United States are well documented. Few studies have evaluated racial-ethnic differences in short-term outcomes following breast cancer surgery. This study compared postoperative outcomes following breast cancer surgery between racial-ethnic groups in the U.

Background: Racial disparities in prostate cancer treatment and survival in the U.S. have been attributed to differences in access to care and medical insurance.
View Article and Find Full Text PDFBackground: In the Military Health System (MHS), women with breast cancer may undergo surgical treatment in military hospitals (direct care) or in the civilian setting via the insurance benefit (private sector care). We conducted this study to determine immediate breast reconstruction rates among women undergoing mastectomy for cancer in the MHS by setting of care.
Methods: Using the linked Department of Defense's Central Cancer Registry and MHS Data Repository, the Department of Defense's medical claims database, we identified adult women who underwent mastectomy for breast cancer from 1998 to 2014.

Background: Racial disparities in treatment and outcomes of rectal cancer have been attributed to patients' differential access to care. We aimed to study treatment and outcomes of rectal cancer in the equal access Military Health System (MHS) to better understand potential racial disparities.
Methods: We accessed the MilCanEpi database to study a cohort of patients aged 18 and older who were diagnosed with rectal adenocarcinoma between 1998 and 2014.

Purpose: We aimed to compare Asian or Pacific Islander, Black, Hispanic, and non-Hispanic White patients in treatment for papillary thyroid cancer (PTC) in the equal access Military Health System to better understand racial-ethnic cancer health disparities observed in the United States.
Methods: We used the MilCanEpi database to identify a cohort of men and women aged 18 or older who were diagnosed with PTC between 1998 and 2014. Low- or high-risk status was assigned using tumor size and lymph node involvement.

Background: Pancreatic cancer has a high case fatality and relatively short survival after diagnosis. Treatment is paramount to improving survival, but studies on the effects of standard treatment by surgery or chemotherapy on survival in U.S.
View Article and Find Full Text PDFObjectives: Pancreatic cancer is often diagnosed at advanced stages with high-case fatality. Many tumors are not surgically resectable. We aimed to identify features associated with survival in patients with surgically nonresected pancreatic cancer in the Military Health System.

The Military Health System (MHS) of the US Department of Defense (DoD) provides comprehensive medical care to over nine million beneficiaries, including active-duty members, reservists, activated National Guard, military retirees, and their family members. The MHS generates an extensive database containing administrative claims and medical encounter data, while the DoD also maintains a cancer registry that collects information about the occurrence of cancer among its beneficiaries who receive care at military treatment facilities. Collating data from the two sources diminishes the limitations of using registry or medical claims data alone for cancer research and extends their usage.
View Article and Find Full Text PDFIntroduction: Identifying low-value cancer care may be an important step in containing costs associated with treatment. Low-value care occurs when the medical services, tests, or treatments rendered do not result in clinical benefit. These may be impacted by care setting and patients' access to care and health insurance.

View Article and Find Full Text PDFObjective: To compare receipt of National Comprehensive Cancer Network Guideline-adherent treatment for gynecologic cancers, inclusive of uterine, cervical, and ovarian cancer, between non-Hispanic White women and racial-ethnic minority women in the equal-access Military Health System.
Methods: We accessed MilCanEpi, which links data from the Department of Defense Central Cancer Registry and Military Health System Data Repository administrative claims data, to identify a cohort of women aged 18-79 years who were diagnosed with uterine, cervical, or ovarian cancer between January 1, 1998, and December 31, 2014. Information on tumor stage, grade, and histology was used to determine which treatment(s) (surgery, chemotherapy, radiotherapy) was indicated for each patient according to the National Comprehensive Cancer Network Guidelines during the period of the data (1998-2014).
Purpose: Exercise is important to address physical and emotional effects of breast cancer treatment. This study examines effects of a personal trainer led exercise intervention on physical activity levels, physical function and quality of life (QoL) in breast cancer survivors.
Methods: Women post active breast cancer treatment were recruited from 2015 to 2017, randomized to immediate exercise or wait-list control, and received three personal training sessions for up to 30 weeks.
Background: The importance of leisure sedentary behavior (LSB) change in diabetes prevention efforts is not well known. This study examines the relationships between changes in self-reported LSB and the primary intervention goals (weight and moderate-intensity to vigorous-intensity physical activity [MVPA]) during a community-based translation of the Diabetes Prevention Program (the Group Lifestyle Balance Program).
Methods: A total of 322 adults at risk for type 2 diabetes were recruited from 3 community centers, a worksite, and military site.

Purpose: Linked cancer registry and medical claims data have increased the capacity for cancer research. However, few efforts have described methods to select information between data sources, which may affect data use. We developed a systematic process to evaluate and consolidate cancer diagnosis and treatment information between the linked Department of Defense Central Cancer Registry (CCR) and Military Health System Data Repository (MDR) administrative claims database, called Military Cancer Epidemiology Data System (MilCanEpi).

In this study, we evaluated surgical disparities between AAW and EAW treated within an equal-access military treatment facility (MTF).
Methods: All AAW (N = 271) and EAW (N = 628) with Stage I-III breast cancer who had their initial diagnosis performed at Murtha Cancer Center at Walter Reed National Military Medical Center were identified.

The US Military Health System (MHS) provides universal access to health care for more than nine million eligible beneficiaries through direct care in military treatment facilities or purchased care in civilian facilities. Using information from linked cancer registry and administrative databases, we examined how care source contributed to cancer treatment cost variation in the MHS for patients ages 18-64 who were diagnosed with colon, female breast, or prostate cancer in the period 2003-14. After accounting for patient, tumor, and treatment characteristics, we found the independent contribution of care source to total variation in cost to be 8 percent, 12 percent, and 2 percent for colon, breast, and prostate cancer treatment, respectively.

Background: Non-Hispanic black (NHB) adults with cancer may have longer time-to-treatment than non-Hispanic whites (NHW) in the United States. Unequal access to medical care may partially account for this racial disparity. This study aimed to investigate whether there were racial differences in time-to-treatment and in treatment delays for patients diagnosed with colon cancer in the equal-access Military Health System (MHS).
