Of note, the patient who responded to sunitinib was also treated with paclitaxel, which our data showed may possibly be active in this illness. A major limitation of this comprehensive molecular profiling is the assessment of response to molecularly targeted matched therapy. We made quite a few treatment recommendations for this distinct patient based around the discussion supplied within the manuscript. These incorporated combination of MEK inhibitors and PI3K inhibitors with or without a taxane primarily based regimen. Regrettably this patient came from a unique country exactly where these drugs usually are not readily available as clinical trials. Additionally, as a result of insurance coverage challenges the patient couldn't be treated on our service. This is a typical problem in clinic particularly since insurance providers usually request a higher level of proof for allowing remedies in even rare diseases.Received: 29 April 2013 Accepted: four July 2013 Published: 30 JulyConclusion In summary, this is the initial report of a entire genomic profile and proteomics analysis of a metastatic phyllodes tumor from the breast. We described an NRAS mutation with concomitant activation of PI3K/Akt/mTOR, suggesting a possible function for a mixture of MEK and PI3K inhibitors. We also identified markers for sensitivity to taxane-based therapies, particularly albumin-bound paclitaxel. Exploring the biology of rare malignancies may be a affordable technique for the improvement of targeted treatments.Competing interests The authors declare no competing interests apart from these talked about in the acknowledgements section.
