The purpose of this study is to determine if an oncolytic virus called Talimogene laherparepvec (a modified herpes simplex 1 virus that can specifically destroy cancer cells while leaving normal cells alone) injected directly into the tumor during chemotherapy prior to surgery can enhance the elimination of triple negative breast cancer tumors. The natural herpes simplex 1 virus typically causes cold sores around the mouth, but the talimogene laherparepvec version of the herpes virus has been changed to prevent it from reproducing in normal tissue. However, it can still attack and break open cancer tissue which is why it is used as a treatment for cancer. It is thought that this virus can also help recruit the participant's immune system to attack the cancer cells during their treatment and possibly destroy the tumor tissue more effectively than chemotherapy alone. This virus is already FDA approved to treat melanoma skin tumors, so investigators want to determine if this virus can achieve a similar benefit in women with triple negative breast tumors.
According to the World Health Organization, breast cancer is the most common cancer in women, and is responsible for 686,000 new cases every year. The WHO also posit that nearly 420,000 women perished from the disease in 2002. Surgery remains the best option for patients presenting with operable Stage I, II or III cancers. Breast conservation surgery has been shown to be as efficacious as mastectomy. About 60-70% of these women with operable breast cancer are breast conservation candidates. However, the need to achieve negative tumor margins often requires a second operation (re-excision) in up to 70% of the women having lumpectomy surgery. Currently, tumor margins assessment in the operating room is often assessed grossly by palpation. The ability to evaluate tumor margin using our proposed intraoperative imaging technique may provide the surgeon with an alternative, and hopefully, more sensitive method to assess tumor margins which may decrease re-excision and the morbidity associated with additional surgery, and, perhaps, lower the risk of local regional recurrence.
Overall rationale: Prophylactic NAC irradiation after nipple-areola sparing mastectomy and immediate reconstruction for patient with ductal carcinoma in-situ or invasive breast cancer will allow better cosmesis and patient's satisfaction: - The use of NAC-sparing mastectomy followed by postoperative NAC (nipple-areola complex) external beam radiotherapy for selected patient with early stage invasive or in-situ breast cancers will be technically feasible and with acceptable complication rates. - The cosmetic results after NAC-sparing mastectomy followed by postoperative external beam radiotherapy to the NAC will be better comparable with Skin Sparing Mastectomy. - The local control rate in the NAC will be more than expected for a NAC sparing mastectomy without postoperative radiotherapy. - The patient's satisfaction after NAC-sparing mastectomy followed by postoperative NAC external beam radiotherapy will be better than after Skin Sparing Mastectomy.
Primary: To determine the pathological remission following the chemotherapy combination docetaxel and doxorubicin in large breast cancer Secondary: - Clinical response rate - To investigate the safety of docetaxel doxorubicin combination in the treatment for neoadjuvant chemotherapy of breast cancer - Type of surgery (radical/conservative)
