Brief Summary

The Tailored Breast Screening Trial (TBST) is a population-based, non-inferiority randomised trial aimed at evaluating the impact of tailored screening strategies addressed to premenopausal women, by using breast density as indicator of risk. 44-45 years old women will be enrolled and invited to undergo a digital mammography. Women are then randomly allocated in two arms. In the intervention arm, women will receive a tailored screening strategy according to breast density. The aim of this study is to assess the impact of a longer screening interval and the reduction of side effects for premenopausal women.

Outcome Measures

Primary Outcomes (2)

  • Comparison of cumulative incidence of interval cancer cases by arm and by density group

    An "interval cancer" is, according to European guidelines for quality assurance, a primary breast cancer which is diagnosed in a woman who had a screening test negative for malignancy within a time period equal to the screening interval. Interval cancers will be retrieved by linking the cancer registry and screening archive. The "cumulative incidence of interval cancers" is the number of interval cancers divided by the number of screened women

    three and six years

  • Comparison of cumulative incidence of T2+/node-positive status breast cancer cases by arm and by density group.

    The "cumulative incidence of T2+/N+ breast cancer" is the number of cancers T2+/N+, regardless the modality of detection (screen-detected, interval cancer, etc.), divided by the number of screened women

    three and six years

Secondary Outcomes (3)

  • Comparison of false positive rates by arm and by density group

    3 and 6 years

  • Comparison of cumulative incidence of breast cancer cases by arm and by density group.

    3 and 6 years

  • Comparison of attendance to mammography screening by arm and by density group.

    1, 2, 3, 4, 5 and 6 year

Study Arms (2)

invitation to mammography screening

ACTIVE COMPARATOR

44-45 years old women in this arm are invited to attend for a mammography screening every 1 year. After the age of 50, all women will continue to be screened in the usual service screening programme.

Other: Annual invitation to mammography

invitation to tailored screening

EXPERIMENTAL

44-45 years old women in this arm with a dense breast (3-4 categories in BI-RADS) at the baseline mammography are invited again after 1 year, while the lower-density group in the intervention arm are invited after 2 years. After the age of 50, all women will continue to be screened in the usual service screening programme.

Other: Tailored screening according to breast density

Interventions

Different interval of mammography screening according to breast density

invitation to tailored screening

Annual interval mammography screening according to international guidelines for women younger than 50 years old

invitation to mammography screening

Eligibility Criteria

You may qualify if:

  • women 44-45 years old resident in the screening area

You may not qualify if:

  • previous diagnosis of invasive or in situ breast cancer
