abstract
Highlights
- •
Examined when women with serous ovarian cancer prefer to be offered genetic testing
- •
The majority felt that the best time for genetic testing was at initial diagnosis.
- •
Family history of cancer was associated with a preference for earlier testing.
Objective
As
treatment based genetic testing becomes a reality, it is important to
assess the attitudes and preferences of women newly diagnosed with
ovarian cancer regarding genetic testing. The objective of this study
was to determine when women with a diagnosis of high grade serous
ovarian cancer would prefer to undergo genetic testing and factors that
influence this preference.
Methods
Women
over 18 years of age with a known diagnosis of high grade serous
ovarian cancer diagnosed between October 2010–2013 were identified via
the Princess Margaret Cancer Center Registry. Participants completed a
questionnaire, which obtained preferences and attitudes towards genetic
testing, cancer history, and demographic information.
Results
120
of the 355 women identified (33.8%) completed the questionnaires. The
median age at time of ovarian cancer diagnosis was 57 years (range
35–84). The majority of participants in this study were offered (94.6%)
and pursued (84.8%) genetic testing. In this cohort, testing was most
frequently offered at diagnosis (41.8%) or during treatment (19.1%). In
this study, women with high grade serous ovarian cancer felt that
genetic testing should be offered before or at the time of diagnosis
(67.8%). Having a family history of breast or ovarian cancer was
significantly (p = 0.012) associated with preferring genetic testing at
an earlier time point in the disease course.
Conclusions
Our
results demonstrate that women with high grade serous ovarian cancer
acknowledge the personal and clinical utility of genetic testing and
support test implementation at the time of cancer diagnosis.
