Hybrid Versus Non-Hybrid Endoscopic Submucosal Dissection for Colorectal Polyps: A Randomized Trial (SHORT-ESD) (SHORT-ESD)

This proposed trial will randomize 60 patients with a ≥20 mm large colorectal polyp to either undergo hybrid or non-hybrid ESD. For the primary comparison (hybrid vs non-hybrid ESD), the primary outcome will be procedure time. We will further examine the safety and efficacy of hybrid ESD compared to non-hybrid …

Axillary Lymph Node Dissection vs Axillary Radiotherapy in Positive Sentinel Node After Neoadjuvant Therapy (ADARNAT)

In the case of primary surgery, in patients with sentinel node involvement, it has already been shown that omitting axillary lymph node dissection (ALND), often combining axillary radiotherapy (RT), does not worsen the prognosis and does significantly reduce the appearance of lymphedema. However, patients who have received neoadjuvant systemic treatment …
