  More info

  Gastric cancer is a worldwide concern, particularly for Indigenous populations who face greater disparities in healthcare. With decreased access to screening and critical treatment delays, this group is experiencing adverse health effects. To determine what factors drive these disparities, a systematic review was performed in PubMed. This revealed a lack of research on gastric cancer specific to this population. The literature primarily focused on subset analyses and biological aspects with sparse focus on determinants of health. The results informed this presentation on factors related to Indigenous gastric cancer, which are influenced by colonialism. Indigenous populations encounter high rates of food shortage, exposure to harmful environmental agents, structural racism in the built environment, , and compromised healthcare quality as an effect of colonialism, which all contribute to the gastric cancer burden. Putting gastric cancer into a cultural context is a potential means to respond to colonial perspectives and their negative impact on Indigenous patients. The objective of this manuscript is to examine the current state of gastric cancer literature from a global perspective, describe what is currently known based on this literature review, supplemented with additional resources due to lack of published works in PubMed, and to present a model of gastric cancer through the lens of a modified medicine wheel as a potential tool to counter colonial healthcare perspectives and to honor Indigenous culture.

  Abstract Background: Type 2 diabetes (T2D) has been associated with increased risk of breast cancer. However, the role of metformin, the first-line anti-diabetic drug, in breast cancer carcinogenesis has not been elucidated completely. We aimed to examine further the association between the use of metformin and other anti-diabetic medication and breast cancer incidence within two large prospective cohort studies. Methods: We followed 184,437 women who participated in the Nurses’ Health Study (NHS;1994-2016) and the NHSII (1995-2017), with the baseline tied to the date metformin was introduced into the United States market. Information on T2D diagnosis, metformin, and other anti-diabetic medication, and other covariates were self-reported at baseline and repeatedly assessed by follow-up questionnaires every two to four years. Breast cancer cases were self-reported and confirmed by medical record review. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between metformin/other anti-diabetic medication use and breast cancer incidence were estimated using Cox proportional hazards regression models. Results: During 3,412,366 person-years of follow-up, we ascertained 9,442 incident invasive breast cancer cases, of which 720 were among women with T2D. Compared with women without T2D (n=168,498), similar risks of developing breast cancer were observed among those who ever used metformin (HR =0.95; 95%CI=0.79-1.13) and among those who received medications other than metformin (HR =1.11; 95%CI=0.91-1.37). Among women with T2D (n=15,939), compared with never metformin users, ever use of metformin overall was not associated with breast cancer (HR =0.90; 95%CI=0.72-1.13), but a lower risk of breast cancer was observed among past metformin users (HR =0.72; 95%CI=0.52-0.99). Longer duration of metformin use was not associated with risk of breast cancer (each 2-year interval: HR =0.98; 95%CI=0.93-1.03, p-trend=0.32). However, among women with substantial weight increase since age 18 (>25 kg), greater than 5 years of metformin use was associated with a lower risk of breast cancer (HR =0.62; 95%CI=0.43-0.89). Conclusion: Although we observed inverse associations among past metformin users, similar associations were not found among current users. Overall, metformin use was not strongly associated with the risk of developing breast cancer among the general cohort population or among women with T2D. Citation Format: Tengteng Wang, Jae H.

  Little is known about the surgical patterns of American Indian/Alaska Native (AI/AN) breast cancer patients. The purpose of this study is to determine whether there are disparities in breast cancer surgery and radiation therapy between non-Hispanic AI/AN (NH-AI/AN) women and non-Hispanic White (NHW) women..Data from the National Program of Cancer Registries of the Centers for Disease Control and Surveillance, Epidemiology, and End Results were used for this cross-sectional study. Female patients with invasive breast cancer diagnosed 2010-2015 were stratified by race/ethnicity, surgical procedure, radiation, and region. Percentage distributions of mastectomy and lumpectomy were compared overall and by region and stage..From 2010 to 2015 there were 3292 NH-AI/AN women and 165,225 NHW women diagnosed with breast cancer. For early stage (AJCC stage 1 and 2), NH-AI/AN women had overall significantly higher percentage of mastectomy (41% vs 34.4%, p

  More info

  Historically, American Indians and Alaska Natives (AI/AN) have been subjected to a lack of control over various aspects of their lives, including their reproductive health. In discussions of family planning with AI/AN patients, clinicians must consider past violations of reproductive rights and the need for transparent consent. This article explores the following questions: What were historical violations of AI/AN women's reproductive rights? How should physicians express respect for this history and for the autonomy of AI/AN female patients regarding surgical sterilization procedures today?

  Many health professions education institutions exist on land once inhabited by American Indians and Alaska Natives (AI/AN). Land acknowledgment by these academic organizations is helpful, but collaborative support of AI/AN health is also needed. Because tribal-university partnerships in education are fewer than in research but just as important, this article considers health professions schools' responsibilities to offer students clinical rotations on tribal lands and to recruit AI/AN students. Such investment expands student educational opportunity, diversifies clinical workforces, and helps tribes improve health infrastructure and sustainability. This article also offers an adaptable roadmap for building such partnerships.

  Colorectal cancer (CRC) is the third most diagnosed cancer in the United States, and many patients unfortunately have metastases at the time of their diagnosis. Cutaneous metastases of CRC have been reported in few journals and primarily as case reports due to their rarity. Here, we present the case of an 83-year-old woman with recently resected colon cancer, T4aN1bMx stage IIIB. She presented to our clinic for evaluation of a right midback mass, and a punch biopsy revealed dermal involvement by invasive, poorly differentiated carcinoma with epidermoid features. The mass was excised, and we ordered a PET scan in search of the primary tumor, which at that time was suspected to be of skin cancer origin. Surprisingly, this revealed a second malignancy triple-negative invasive ductal carcinoma of the left breast. The back mass stained positive for CK20, which was compatible with a metastasis from a colonic primary. After initially declining adjuvant therapy, the patient completed one cycle of capecitabine and oxaliplatin, which she tolerated poorly. She continued to further decline, developed widespread cutaneous metastases, and went home on hospice. Cutaneous lesions are an exceedingly rare site of metastasis for colon adenocarcinoma, and their clinical presentation can vary widely. It is important for providers to investigate any new skin lesion in a patient with a recent or remote history of malignancy, even if there were no sites of distant metastasis at initial diagnosis.

Surgical and molecular characterization of primary and metastatic disease in a neuroendocrine tumor arising in a tailgut cyst. Cold Spring Harbor molecular case studies, 4(5).
  More info

  Neuroendocrine tumors (NETs) arising from tailgut cysts are a rare but increasingly reported entity with gene expression profiles that may be indicative of the gastrointestinal cell of origin. We present a case report describing the unique pathological and genomic characteristics of a tailgut cyst NET that metastasized to liver. The histologic and immunohistochemical findings were consistent with a well-differentiated NET. Genomic testing indicates a germline frameshift in and a few somatic mutations of unknown significance. Transcriptomic analysis suggests an enteroendocrine L cell in the tailgut as a putative cell of origin. Genomic profiling of a rare NET and metastasis provides insight into its origin, development, and potential therapeutic options.

  Many modifiable lifestyle factors have been associated with colon cancer risk, but less is known about their effect on disease when considered together. Estimating the proportion of colon cancer cases that could be prevented by the adoption of combined modifiable lifestyle behaviors will provide important insights into disease prevention.

  A team of Indigenous researchers at the University of Arizona is out this week with new findings that shed light on access to care for Native American women.When it comes to breast cancer treatment, there are two approaches: a mastectomy, where the entire breast is removed, or a lumpectomy, also known as breast-conserving surgery. While it’s always case by case, outcomes for women who undergo both approaches are the same, and patients report less pain and better quality of life with lumpectomies.But, it’s time consuming — paired with often daily radiation treatments. And that could prove difficult for patients who live on remote reservation land.Jennifer Erdrich is an assistant professor of surgery at University of Arizona College of Medicine, and she helped lead the research. The Show spoke with her to learn about the disparities they found.
