Background/aim
The Trento screening program transitioned to digital breast tomosynthesis (DBT) screening based on evidence that DBT improves breast cancer (BC) detection compared to mammography; an evaluation of the transition to DBT is reported in this pilot study.
Methods
Prospective implementation of DBT screening included women aged ≥50 years who attended the Trento program for biennial screening. DBT screening included DBT acquisitions with synthesized 2D-images. A historical cohort of women who attended the program (January 2013–October 2014) and received digital mammography (DM) provided a comparison group. Independent double-reading (with a third arbitrating read for discordance) was used for DBT and DM screening. Screening outcomes included
cancer detection rate
(CDR/1000 screens), percentage of screens recalled to assessment (recall%),
interval cancer rate
(ICR/1000 screens) at 2-year follow-up, and screening sensitivity. Rate ratios (RR) and 95% confidence interval (95%CI) examined outcomes for DBT versus DM screening.
Results
From women aged 50–69 years who accepted an invitation to screening (October 2014–October 2016) 46,343 comprised the DBT-screened group: amongst these 402 BCs (includes 50 ductal carcinoma in-situ (DCIS)) were detected (CDR 8.67/1000), whereas 205 BCs (includes 33 DCIS) were detected amongst 37,436 DM screens (CDR 5.48/1000) [RR for CDR:1.58 (1.34–1.87)]. Recall% was lower for DBT (2.55%) than DM (3.21%) [RR:0.79 (0.73–0.86)]. Compared to DM, DBT screening increased CDR for stage I-II BC, for all tumour size and grade categories, and for node-negative BC, but did not increase CDR for DCIS. Estimated ICR for DBT was 1.1/1000 whereas ICR for DM was 1.36/1000 [RR:0.81 (0.55–1.19)]. Screening sensitivity was 88.74% for DBT versus 80.08% for DM [RR:1.11 (0.94–1.31)].
Conclusion
DBT significantly improved early-detection measures but did not significantly reduce ICR (relative to DM screening), suggesting that it could add benefit as well as adding over-detection in population BC screening.
Although synovitis is recognized as a marker of joint disease activity, its periodic assessment is not included in routine clinical surveillance of patients with haemophilia (PwH). In order to evaluate the current knowledge and to identify controversial issues, a preliminary literature search by the Musculoskeletal Committee of the Italian Association of Haemophilia Centres (AICE) has been conducted. Statements have been established and sent to the Italian AICE members to collect their level of agreement or disagreement by a Delphi process. Thirty-seven consensus recommendations have been drafted. We found a general agreement on the indication to consider the presence of synovitis as a marker of joint disease activity in PwH. Accordingly, there was agreement on the indication to search for synovitis both in patients reporting joint pain and in asymptomatic ones, recognizing ultrasound as the most practical imaging technique to perform periodic joint screening. Interestingly, after detection of synovitis, there was agreement on the indication to modify the therapeutic approach, suggesting prophylaxis in patients treated on demand and tailoring treatment in patients already under prophylaxis. Whereas the need of an early consultation with a physiotherapist is recommended for PwH affected by chronic synovitis, the exact timing for an orthopaedic surgeon consultation is currently unknown.
The presence of axillary enlarged lymph nodes in the follow-up of a woman with a history of breast cancer should always be thoroughly indagated. Dermatopathic lymphadenopathy presents a specific pathologic pattern found within the lymph nodes and is usually associated with cutaneous rashes. Patients with various skin conditions can develop regional lymphadenopathy, which can result in the asymptomatic enlargement of the lymph nodes, especially in the inguinal, axillary and cervical regions. Dermatopathic lymphadenopathy should be considered in the differential diagnosis also in patients with minimal cutaneous findings. Dermatopathic lymphadenopathy is a benign process and management of these patients consists in simple clinical, mammographic and ultrasonographic follow-up.
