Assessment of family history of colorectal cancer in primary care: perceptions of first degree relatives of people with colorectal cancer

Familial colonoscopic screening: how do French general practitioners deal with patients and their high-risk relatives. A qualitative study

Background

Screening of colorectal cancer (CRC) can reduce incidence and mortality. First-degree relatives (FDRs) of patients with CRC or advanced adenoma before the age of 65 (index patients) are at increased risk of CRC; however, the guidelines for screening of FDRs by colonoscopy are poorly followed.

Objectives

The present study, conducted in the context of the COLOR3 interventional study project, aimed to explore the positioning of general practitioners (GPs) in familial CRC screening in France.

Methods

From February 2020 to April 2021, 35 semi-structured interviews with GPs of index patients and/or their FDRs were conducted by telephone. The full-data transcribed corpus was subjected to horizontal thematic analysis.

Results

Knowledge and compliance with the guidelines vary greatly between GPs. Although initiating the diagnostic process, GPs do not consider themselves as actors in the flow of information concerning familial risk. Their accompaniment of index patients in this role varies. GPs should overcome barriers to implementing colonoscopic screening for FDRs. They underline the importance of exploring family history, but they lack the time and doubt the reliability of the information given by FDRs.

Conclusion

Challenges include circumventing gaps in knowledge, adherence to guidelines and improving family history updates. The GPs interviewed suggested personalised guidelines in specialists' reports to initiate information campaigns raising awareness of familial risk, and to enhance coordination between organised screening and familial screening.

Factors Associated With Colorectal Cancer Screening Among First-Degree Relatives of Patients With Colorectal Cancer in China

BACKGROUND

First-degree relatives of patients with colorectal cancer have an elevated risk of colorectal cancer. However, the behavior and factors potential influencing first-degree relatives regarding colorectal cancer screening in China remain unknown.

OBJECTIVE

The aim of this study was to explore the screening behavior and related factors of first-degree relatives of colorectal cancer patients.

METHODS

A cross-sectional design was applied, and 201 first-degree relatives participated from August 2018 to July 2019. Data were collected about demographic information, the "Colorectal Cancer Perceptions Scale," and screening behavior of first-degree relatives. Factors associated with screening behavior were identified using logistic regression analysis.

RESULTS

Only 18.9% of first-degree relatives had participated in colonoscopy screening. Two Health Belief Model factors were the influencing factors of their participation in colorectal cancer screening. Higher possibility of colorectal cancer screening of first-degree relatives was associated with higher perceived susceptibility (odds ratio, 1.224; 95% confidence interval, 1.075-1.395) and lower perception of barriers (odds ratio, 0.880; 95% confidence interval, 0.820-0.944) of first-degree relatives.

CONCLUSIONS

Participation in colorectal cancer screening by first-degree relatives requires improvement; perceived susceptibility and perception of barriers were the most important predictors.

IMPLICATIONS FOR PRACTICE

Health professionals can enhance awareness of colorectal cancer susceptibility and address barriers to colorectal cancer screening among first-degree relatives at both individual and social levels.

The enduring importance of family health history in the era of genomic medicine and risk assessment

Improving disease risk prediction and tailoring preventive interventions to patient risk factors is one of the primary goals of precision medicine. Family health history is the traditional approach to quickly gather genetic and environmental data relevant to the patient. While the utility of family health history is well-documented, its utilization is variable, in part due to lack of patient and provider knowledge and incomplete or inaccurate data. With the advances and reduced costs of sequencing technologies, comprehensive sequencing tests can be performed as a risk assessment tool. We provide an overview of each of these risk assessment approaches, the benefits and limitations and implementation challenges.

Invitation to Screening Colonoscopy in the Population at Familial Risk for Colorectal Cancer

BACKGROUND

Screening colonoscopy can lower the incidence of colorectal cancer (CRC), yet participation rates are low even in groups at high risk. The goal of this study was to double the rate of participation in screening colonoscopy among persons at familial risk and then to determine the frequency of neoplasia in this risk group.

METHODS

In a nationwide, cluster-randomized, multicenter study, first-degree relatives (FDR) of patients with CRC across Germany received written informational materials concerning the familial risk of CRC, along with an invitation to undergo colonoscopy. Participants in the intervention group were additionally counseled by nurses over the telephone. The primary endpoint of the study was colonoscopy uptake within 30 days.

RESULTS

The participants' mean age was 50.8 years. The colonoscopy uptake rates were 99/125 (79%) in the intervention group and 97/136 (71%) in the control group (RR = 1.11; 95% confidence interval [0.97; 1.28]). A polypectomy was performed in 72 of 196 asymptomatic persons (37%). In 13 cases (7%), an advanced neoplasia was detected; two of these persons had colon cancer (stages T0 and T1). 42% of the participants expressed barriers against colonoscopy. 22 reported mild side effects; there were no serious side effects.

CONCLUSION

Additional counseling by nurses over the telephone does not increase the participation rate. Approaching patients who have CRC is an opportunity to increase the participation of their first-degree relatives in screening colonoscopy. The frequency of neoplasia that was found in this study underscores the need to screen relatives even before they reach the usual age threshold for screening.

Awareness of health sciences students about colorectal cancer risk factors

OBJECTIVE

This descriptive study was conducted in order to determine the risk factors, symptoms and awareness of health sciences students with regards to colorectal cancer (CRC).

METHODS

This study included 1,028 health science students from two different universities. Data for this study were collected via a questionnaire form that included questions about CRC risk factors, protective approaches and symptoms. Frequencies, percentages and averages of the data were assessed with Kruskal-Wallis and Mann-Whitney U tests.

RESULTS

The most frequent risk factors of the students (mean age: 21.25 years) were smoking (90.5%), excessive alcohol consumption (87.4%), family history of cancer (84.2%) and obesity (82.6%), while the most common protective approaches were smoking cessation, avoiding alcohol, regular physical activity and a low-fat diet. There was a significant difference in the CRC awareness of students in terms of gender, the department and grade level at which they were studying, and having a family history of cancer.

CONCLUSION

Results of this study revealed that students had a sufficient awareness about risk factors and what they could do to diminish their risk, but their knowledge about CRC symptoms was less than expected. We believe that health sciences students should be given more education on CRC symptoms.

Gastrointestinal cancer risk in patients with a family history of gastrointestinal cancer

Background/Aims

This study was performed to evaluate the relationship between family history of gastrointestinal (GI) cancers and incidence of any GI cancer in the Korean population.

Methods

Between January 2015 and July 2016, 711 GI cancer patients and 849 controls in 16 hospitals in Korea were enrolled. Personal medical histories, life styles, and family history of GI cancers were collected via questionnaire.

Results

There was a significant difference in the incidence of family history of GI cancer between GI cancer patients and controls (p=0.002). Patients with family history of GI cancer tended to be diagnosed as GI cancer at younger age than those without family history (p=0.016). The family members of GI cancer patients who were diagnosed before 50 years of age were more frequently diagnosed as GI cancer before the age of 50 years (p=0.017). After adjusting for major confounding factors, age (adjusted odds ratio [AOR] 1.065, 95% confidence interval [CI]; 1.053-1.076), male gender (AOR 2.270, 95% CI; 1.618-3.184), smoking (AOR 1.570, 95% CI; 1.130-2.182), and sibling's history of GI cancer (AOR 1.973, 95% CI; 1.246-3.126) remained independently associated with GI cancers.

Conclusions

GI cancer patients tended to have a first relative with a history of concordant GI cancer. Personal factors (old age and male) and lifestyle (smoking) contribute to the development of GI cancer, independently. Individuals with high risk for GI cancers may be advised to undergo screening at an earlier age.

Barriers to Colorectal Cancer Screening in a Primary Care Setting in Turkey

Colorectal cancer (CRC) is the third most common form of cancer in men worldwide and the second most common in women. The purpose of this study was to determine both barriers established by primary health care providers (PHCPs) and barriers perceived by them and to produce solutions for achieving the desired results. A four-part questionnaire was administered to family physicians (FPs) and family health personnels (FHPs) in Samsun, Turkey on 01-15 May, 2016. Sixty-six percent of PHCPs were contacted. Data were evaluated as numbers and percentages, and statistical significance was analyzed using the Chi square and t tests. 478 PHCPs participated; 49.4 % were FPs and 50.6 % FHPs. Of the participants, 86.6 % stated that they performed CRC screening on patients. The level of participants knowing that screening should start at age 50 and conclude at age 70 was 49.7 %. The level of subjects requesting the fecal occult blood test (FOBT) at the correct intervals was 29.7 %, but only 6.9 % recommended colonoscopy at the correct intervals. Additionally, 18.2 % of subjects knew that the test used is immunochemical FOBT, and 60.5 % reported not using reminders. PHCPs' low levels of knowledge, awareness and advice compatible with guidelines concerning CRC screening may represent an obstacle to such screening. Barriers perceived by PHCPs include patients' inability to access definite medical information, deficiencies in the reminder system and patients' lack of interest in CRC screening. Additions to the screening program will be useful in overcoming barriers.

The KinFact intervention - a randomized controlled trial to increase family communication about cancer history

BACKGROUND

Knowing family history is important for understanding cancer risk, yet communication within families is suboptimal. Providing strategies to enhance communication may be useful.

METHODS

Four hundred ninety women were recruited from urban, safety-net, hospital-based primary care women's health clinics. Participants were randomized to receive the KinFact intervention or the control handout on lowering risks for breast/colon cancer and screening recommendations. Cancer family history was reviewed with all participants. The 20-minute KinFact intervention, based in communication and behavior theory, included reviewing individualized breast/colon cancer risks and an interactive presentation about cancer and communication. Study outcomes included whether participants reported collecting family history, shared cancer risk information with relatives, and the frequency of communication with relatives. Data were collected at baseline, 1, 6, and 14 months.

RESULTS

Overall, intervention participants were significantly more likely to gather family cancer information at follow-up (odds ratio [OR]: 2.73; 95% confidence interval [CI]: 2.01, 3.71) and to share familial cancer information with relatives (OR: 1.85; 95% CI: 1.37, 2.48). Communication frequency (1=not at all; 4=a lot) was significantly increased at follow-up (1.67 vs. 1.54). Differences were not modified by age, race, education, or family history. However, effects were modified by pregnancy status and genetic literacy. Intervention effects for information gathering and frequency were observed for nonpregnant women but not for pregnant women. Additionally, intervention effects were observed for information gathering in women with high genetic literacy, but not in women with low genetic literacy.

CONCLUSIONS

The KinFact intervention successfully promoted family communication about cancer risk. Educating women to enhance their communication skills surrounding family history may allow them to partner more effectively with their families and ultimately their providers in discussing risks and prevention.

Implementation of screening colonoscopy amongst first- degree relatives of patients with colorectal cancer in Turkey: a cross-sectional questionnaire based survey

OBJECTIVE

To evaluate the implementation of screening colonoscopy amongst first-degree relatives (FDRs) of patients with colorectal cancer (CRC) in Turkey.

MATERIALS AND METHODS

A total of 400 first-degree relatives (mean(SD)age: 42.5(12.7) years, 55.5% were male) of 136 CRC patients were included in this cross-sectional questionnaire based survey. Data on demographic characteristics, relationship to patient and family history for malignancy other than the index case were evaluated in the FDRs of patients as were the data on knowledge about and characteristics related to the implementation of screening colonoscopy using a standardized questionnaire form.

RESULTS

The mean(SD) age at diagnosis of CRC in the index patients was 60.0(14.0) years, while mean(SD) age of first degree relatives was 42.5(12.7) years. Overall 36.3% of relatives were determined to have knowledge about colonoscopy. Physicians (66.9%) were the major source of information. Screening colonoscopy was recommended to 19.5% (n=78) of patient relatives, while 48.7% (n=38) of individuals participated in colonoscopy procedures, mostly (57.9%) one year after the index diagnosis. Screening colonoscopy revealed normal findings in 25 of 38 (65.8%) cases, while precancerous lesions were detected in 26.3% of screened individuals. In 19.0% of FDRs of patients, there was a detected risk for Lynch syndrome related cancer.

CONCLUSIONS

In conclusion, our findings revealed that less than 20% of FDRs of patients had received a screening colonoscopy recommendation; only 48.7% participated in the procedure with detection of precancerous lesions in 26.3%. Rise of awareness about screening colonoscopy amongst patients with CRC and first degree relatives of patients and motivation of physicians for targeted screening would improve the participation rate in screening colonoscopy by FDRs of patients with CRC in Turkey.
