Use of imaging in surveillance of women with early stage breast cancer

Intended follow up of women with breast cancer at low risk of recurrence and at least 5 years from diagnosis

BACKGROUND

Although there is evidence that minimal surveillance is compatible with an optimal outcome in women after early stage breast cancer, little is known of the surveillance that these women receive.

AIMS

To describe the intended clinical follow up and patterns of use of imaging modalities in low-risk breast cancer survivors who are at least 5 years from diagnosis.

METHODS

Participants in the Bupa Health Foundation Health and Wellbeing After Breast Cancer Study with stage 1 invasive breast cancer at diagnosis, who had survived free of recurrence or new primary breast cancer for at least 5 years, provided information for this analysis.

RESULTS

The most common choice of physician follow up was with one doctor only (54%). Within this group, the most frequent choice was a general practitioner (GP) (63%) followed by medical oncologist (23%). Thirty-five per cent of women said that they intended to consult two doctors and within this group, the most common combination was a GP and a medical oncologist (45%). This was despite two out of three women reporting being advised that there was no need to consult a medical oncologist. Over 90% of women reported having a mammogram with, or without, breast ultrasound in the previous 12 months. There was a low rate of use of other imaging tests in the absence of clear indications.

CONCLUSIONS

Minimising unnecessary medical consultations by women with breast cancer at low risk of recurrence 5 years from diagnosis will require education about the benefits of a minimal surveillance strategy.

Breast cancer "tailored follow-up" in Italian oncology units: a web-based survey

Purpose

Breast cancer follow-up procedures after primary treatment are still a controversial issue. Aim of this study was to investigate, through a web-based survey, surveillance methodologies selected by Italian oncologists in everyday clinical practice.

Methods

Referents of Italian medical oncology units were invited to participate to the study via e-mail through the SurveyMonkey website. Participants were asked how, in their institution, exams of disease staging and follow-up are planned in asymptomatic women and if surveillance continues beyond the 5^th year.

Results

Between February and May 2013, 125 out of 233 (53.6%) invited referents of Italian medical oncology units agreed to participate in the survey. Ninety-seven (77.6%) referents state that modalities of breast cancer follow-up are planned according to the risk of disease progression at diagnosis and only 12 (9.6%) oncology units apply the minimal follow-up procedures according to international guidelines. Minimal follow-up is never applied in high risk asymptomatic women. Ninety-eight (78.4%) oncology units continue follow-up in all patients beyond 5 years.

Conclusions

Our survey shows that 90.4% of participating Italian oncology units declare they do not apply the minimal breast cancer follow-up procedures after primary treatment in asymptomatic women, as suggested by national and international guidelines. Interestingly, about 80.0% of interviewed referents performs the so called “tailored follow-up”, high intensity for high risk, low intensity for low risk patients. There is an urgent need of randomized clinical trials able to determine the effectiveness of risk-based follow-up modalities, their ideal frequency and persistence in time.
