Patients with operable, primary invasive noninflammatory early TNBC of stage I-IIIB and pathologically verified residual cancer cells (no pathological complete response) after neoadjuvant chemotherapy then underwent adjuvant treatment with gemcitabine plus cisplatin Pt will be followed up every 3 month in first year then every 6 month in the second year then followed up yearly Study will be conducted at Assiut University Hospital with sample size calculation BRACA will be done

2 years disease free survival which is calculated since time of surgery till occurance of local or distant recurrence

Compare if the investigated regimen is superior or same as standard regimen and the investigators will notice and document toxicity of both regimens including gastrointestinal toxicity, neurological toxicity, hematologic toxicity renal toxicity, ototoxicity and skin toxicity according to CTCAE version 4.1 also over all survival will be measured which is calculated from time of diagnosis till death or finishing our study minimum 3 years
