Nab-paclitaxel after docetaxel hypersensitivity reaction: case report and literature review.

Taxanes, including paclitaxel and docetaxel, are one of the most active cytotoxic agents in breast cancer  treatment  including  Her-2  positive  subtype characterized  by  aggressive  clinical  and pathological features since the early stage. However, their use is sometimes limited by the occurrence of hypersensivity reactions (HSRs) characterized by erythematous rashes, bronchospasm, respiratory distress, hypotension, and pulmonary edema. Cross-reactions between paclitaxel and docetaxel are described in literature with a rate ranging from 49% to 90%.

Triple negative status and BRCA mutations in contralateral breast cancer: a population-based study.

Background And Aim Of The Work: BRCA1/2 mutation carriers diagnosed with breast cancer have a strong life-time risk of developing contralateral breast cancer (CBC). We performed a population-based study with the aim of estimating the proportion of CBC associated with BRCA1/BRCA2 mutations, and the contribution of germline mutations to both molecular and clinical features of these tumors.

Methods: Fifty-five women with invasive CBC consecutively seen at the at the Genetic Oncology Service of the University Hospital of Parma from 2000 to 2011 were subjected to BRCA1/2 testing.
