In our study, 27.1% were managed in the MDT clinic that mandated the participation of at least four to five board\u2010certified multidisciplinary experts and patients in decision\u2010making processes, while the rest were managed through diverse MDT approaches such as conferences, tumor board meetings, and discussions conducted via phone calls or email. Management in MDT clinic was significantly associated with more use of radiotherapy (<jats:italic>p<\/jats:italic>\u2009=\u20090.003) and more sessions of local therapy (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). At the time of MDT clinic, the number of lesions was 1, 2\u20135, and\u2009&gt;5 in 9 (13.6%), 35 (53.1%), and 19 (28.8%) patients, respectively.
