The Alaska Native Tumour Registry: fifty years of cancer surveillance data for Alaska Native people.

Like other Indigenous Circumpolar populations, Alaska Native (AN) people experience different patterns of cancer than their non-Indigenous counterparts. Every 5 years, the Alaska Native Tumour Registry releases a comprehensive report on cancer among AN people; this study provides 50 years of cancer surveillance data. Five-year annual-average age-adjusted incidence rates were calculated for time-periods ranging 1969-2018. AN data were compared with data for US whites (SEER 9). Mortality rates were calculated for 1994-2018 using data from the National Center for Health Statistics. During 2014-2018, there were 2,401 cases of invasive cancer among AN people. Among these, the most commonly diagnosed cancers were colorectal (405 cases, 17% of all cancers), lung and bronchus (373 cases, 16% of all cancers), and female breast (340 cases, 14% of all cancers). Lung cancer was the leading cause of cancer death, followed by colorectal and female breast cancers. These leading cancers are screenable, and preventable through lifestyle modifications including tobacco cessation, healthy eating and engaging in physical activity. These data provide important information to support cancer prevention and control among AN people. Cancer surveillance has been a valuable tool throughout the Circumpolar North to support reducing the burden of cancer among Indigenous populations.Abbreviations: ANAI: Alaska Native/American Indian; AN: Alaska Native; USW: U.S. White(s); ANMC: Alaska Native Medical Center; ANTR: Alaska Native Tumour Registry; IR: Incidence Rate; CI: Confidence Interval; RR: Rate Ratio; ICD-O-3: International Classification of Diseases for Oncology - Third Edition; SEER: Surveillance, Epidemiology and End Results.

Gastric Cancer in Alaska Native and American Indian People Living in Alaska, 1990-2017.

INTRODUCTION: Alaska Native (AN) people experience a high burden of gastric cancer compared with other US Native and non-Native populations. Previous reports have suggested that gastric cancer in AN people occurs at a younger age and is a more aggressive pathologic type. We evaluated all cases of gastric cancer in AN people from 1990 to 2017 and compared the epidemiologic and pathologic characteristics with the gastric cancers that occurred in the same time in the US white (USW) population. METHODS: Cancer data were collected by the Alaska Native Tumor Registry and National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Comparisons were performed looking at the age and sex distribution of the affected AN and USW people, as well as the cancer characteristics, including the location, stage, and pathology. RESULTS: The age distribution was significantly different between AN and USW patients (P < 0.001), with a greater proportion of AN people diagnosed younger than 40 years (11% vs 3%, P < 0.0001) and 40-59 years (37% vs 20%, P < 0.0001). In addition, a greater proportion of AN people were diagnosed with distant stage cancer (AN: 48% and USW: 35%, P < 0.0001). The age-adjusted rate of gastric cancer in the AN population was significantly higher than the USW population (20.8 vs 6.7 per 100,000 persons, P < 0.0001). Although there has been a significant decrease in the gastric cancer incidence rate in the USW population, no significant change in incidence was seen in the AN population. DISCUSSION: This study highlights the disproportionate burden of gastric cancer in the AN population. Further work is needed to address and understand this disparity.

Interprofessional conflict and conflict management in an educational setting.

Background: Whenever health professionals work together as a team, conflict is inevitable - some would argue even necessary. However, conflict can have negative effects on patient care, job satisfaction, personal wellness, and professional productivity. Purpose: This study aims to describe interprofessional conflicts in a hospital setting from the perspective of three groups of health science students. Methods: An online questionnaire survey collected data from 225 health science students (medicine, nursing, and social work) in Northern California (USA). Quantitative and qualitative analyses were conducted resulting in seven central themes of conflict. Results: There are differences among health professional students in terms of how conflict is experienced and managed. Nursing students and medical students were more likely to take on the "victim" role when explaining their conflict, and their conflicts were more likely to be intra-professional. The most common cause of conflicts was related to hierarchy and power issues. The majority were dissatisfied with the way the conflict was resolved. Conclusions: Findings from this study can be used to design interprofessional curriculum to improve outcomes from conflicts and improve wellbeing, job satisfaction, and reduce patient turnover.
