NCT03374826
Axillary lymph node status is an important prognostic factor for patients with breast cancer. After breast cancer diagnosis, current nodal staging consists of axillary ultrasound (US) combined with tissue sampling when deemed necessary. In case of positive axillary lymph nodes, patients will undergo axillary lymph node dissection (ALND). In case of no suspicious axillary lymph nodes (i.e. clinically node negative patients), patients will undergo sentinel lymph node biopsy (SLNB). This surgical nodal staging is accompanied by co-morbidity. In theory, if non-invasive imaging can evaluate the lymph node status accurately, a node negative patient would no longer have to undergo axillary surgery. Since MRI is suitable for soft tissue imaging and PET has the advantage of showing increased metabolic uptake in lymph node metastases, a combination of these techniques in hybrid PET/MRI would be highly desirable. If dedicated axillary hybrid PET/MRI is equally accurate to SLNB for the detection of negative axillary lymph nodes, work-up could be more efficient by bypassing SLNB. However, the accuracy of dedicated axillary hybrid PET/MRI needs to be compared with the pathological outcome of SLNB (gold standard) first.

By introducing pulse oximetry, with or without clinical decision support algorithms, to primary care facilities in India, Kenya, Senegal and Tanzania, the Tools for Integrated Management of Childhood Illness (TIMCI) project aims to contribute to reducing morbidity and mortality for sick children under-five while supporting the rational and efficient use of diagnostics and medicines by healthcare providers. The multi-country, multi-method evaluation aims to generate evidence on the health and quality of care impact, operational priorities, cost and cost-effectiveness of introducing these tools to facilitate national and international decision-making on scale-up.
