Moderators of cancer-related distress and worry after a pancreatic cancer genetic counseling and screening intervention.

OBJECTIVES: Although the hereditary breast and ovarian cancer literature has demonstrated short-term gains in psychological adjustment following genetic counseling, there has been limited research examining long-term outcomes and moderators. Moreover, there has been minimal research into the psychological effects of this intervention in populations at high risk for pancreatic cancer. This study examines the long-term effects of pancreatic cancer screening and genetic counseling on cancer-related distress and cancer worry in a high-risk population at 1-year follow-up. Additionally, this study explores potential moderators of the effectiveness of this intervention. METHODS: One hundred twenty-nine participants with familial pancreatic cancer or with the BRCA2 gene mutation completed a baseline questionnaire prior to their first pancreatic cancer screening and genetic counseling session. Participants also completed questionnaires at 3- and 12-month follow-up. RESULTS: Cancer-related intrusive thoughts decreased significantly over time, whereas cancer-related worry decreased at 3 months and showed a small but significant increase at 1 year. Age and baseline distress exhibited moderator effects. Younger individuals showed a significant decrease in cancer-related intrusive thoughts, cancer-related avoidant thoughts, and cancer worry. Additionally, individuals with greater baseline distress showed a significant decrease in cancer-related intrusive thoughts over time. CONCLUSIONS: Analysis of the long-term effects of pancreatic cancer screening and genetic testing reveal psychological gains that are maintained at 1-year follow-up. This intervention is particularly effective for younger participants and individuals with greater baseline distress.

Pancreatic cancer risk counselling and screening: impact on perceived risk and psychological functioning.

Individuals at increased risk for pancreatic cancer who undergo screening can experience psychological and emotional distress. The objective of this study is to determine whether individuals participating in a pancreatic cancer screening program experience disruptions in risk perception, cancer-related anxiety or emotional distress. A pretestposttest design was used to examine perceived risk and psychological functioning of individuals participating in a pancreatic cancer screening protocol. The screening protocol includes genetic counselling, transcutaneous abdominal ultrasound, magnetic resonance imaging, and blood collection and eligible participants included individuals with a family history of pancreatic cancer or BRCA2 mutation carriers. At baseline, participants (n = 198) showed low to moderate levels of risk perception, pancreatic cancer-related anxiety, and general distress. Participants with familial pancreatic cancer (FPC) (n = 131) endorsed higher risk perception of pancreatic cancer than the BRCA2 carriers (n = 67) (perceived lifetime risk 42 vs. 15%), but did not differ on cancer worry or general distress prior to the first study appointment. From baseline to 3 months follow-up, no significant time or time by group interactions emerged on risk perception or general distress, but cancer worry decreased over time for the FPC group regardless of the number of affected relatives. Our findings indicate that participation in a pancreatic cancer screening program does not lead to a significant increase in risk perception, cancer worry, or general distress and that participants with high baseline levels of risk perception and distress may benefit from a more comprehensive risk assessment and psychological support.
