OPTimizing Irradiation Through Molecular Assessment of Lymph Node (OPTIMAL)
In Brief
A clinical study evaluating Irradiation for Breast Cancer. Completed, enrolled 489 participants across 50 sites in 3 countries.
Detailed Summary
The main purpose of this study is to show the non-inferiority of the incidental irradiation, as compared to intentional irradiation of the axillary nodes, in terms of 5-years disease-free survival (DFS) of early stage breast cancer patients with limited affectation of sentinel node assessed by OSNA (250 to 15,000 copies/uL), treated with breast-conservative surgery without axillary lymphadenectomy.
Study Details
Timeline
Interventions
Intentional versus incidental irradiation of lymphatic node areas, administered using a lineal accelerator, after 3D delimitation of the supraclavicular and axillary levels I, II and III. In both treatment arms, further tumoral bed boost will be allowed according to the investigator criteria, whether dose contribution to the nodal areas can be calculated. Due to its nature, interventions cannot be asked.
