Non-Response of Epstein-Barr Virus-Associated Breast Cancer after Primary Chemotherapy: Report of Two Cases.

Based on epidemiological evidence and molecular findings, a possible association of Epstein-Barr virus (EBV) with the carcinogenesis of breast cancer has been described. However, the frequency of EBV in breast cancer and the role of EBV regarding tumor progression or therapeutic results is largely unexplored. Here, we report on two cases of advanced, lymph node-positive invasive breast cancer of no special type (NST), histologically showing no clinical or histological evidence of tumor regression as an equivalent of a lack of response to primary systemic therapy.

Phoenix atherectomy for patients with peripheral artery disease.

Background: Endovascular atherectomy enables minimally invasive plaque removal in peripheral artery disease (PAD).

Aims: We aimed to evaluate the safety and the long-term effectiveness of the Phoenix atherectomy for the treatment of complex and calcified lesions in PAD patients.

Methods: Consecutive all-comer patients with PAD underwent the Phoenix atherectomy.

Safety, effectiveness and mid-term follow-up in 136 consecutive patients with moderate to severely calcified lesions undergoing phoenix atherectomy.

To investigate the safety and effectiveness of the Phoenix atherectomy device for the treatment of complex and calcified lesions in patients with peripheral artery disease (PAD). 136 consecutive all-comer patients with chronic PAD underwent Phoenix atherectomy. Safety in terms of vessel injury and embolism, efficacy and clinical success in terms of ≥ 1Rutherford class (RF) improvement during follow-up were systematically analyzed.
