How would you treat a patient who had bilateral mastectomies for a bilateral squamous cell carcinoma of the breast with a positive lymph node?   

This is aggressive variant of metaplastic carcinoma with a high risk of locoregional and distant metastasis despite treatment. I would treat chest wall and axilla for sure and would add supraclav field if the axilla nodal burden is high.  ‘I would treat to 60 Gy in 30 fractions
