Therapeutically relevant subgroups of these cancers are increasingly being recognized, and therapies are being developed to deal with them. These novel therapies are not targeting triple-negative tumors uniquely, but rater targeting the more unfavorable subgroups. Some triple-negative cancers have very good prognosis if pathologically complete response can be obtained after chemotherapy. At the present time neoadjuvant chemotherapy provides a way to distinguish favorable from unfavorable subgroups.engMahidol UniversityArticleDepartment of surgery Faculty of Medicine Ramathibodi Hospital Mahidol University
