Hi Kristyna,

I have found an interesting article just recently published in Oncotarget by Chen et al. 'Post-operative radiotherapy is beneficial for T1/T2 triple negative breast cancer patients with four or more positive lymph nodes'. I hope this helps. They included more than 900 mamm. CA patients who were diagnosed triple negative. At least the comparison of pre- and post-treatment in terms of radiotherapy is investigated here...

All the best to Brno!

Nico

Thank you!
