Osteonecrosis and osteomyelitis (first report withepirubicin): case report

A woman developed osteonecrosis and osteomyelitisduring treatment for breast cancer including docetaxel[Taxotere], epirubicin, cyclophosphamide [Exdoxan; sic],goserelin [Zoladex] and tamoxifen [dosages and durationsof therapies to reaction onset not stated].

The woman presented at 37 years of age, in April 2006,with invasive ductal carcinoma. She underwent a modifiedradical mastectomy, followed by five courses ofchemotherapy with docetaxel, epirubicin andcyclophosphamide, as well as hormone therapy withtamoxifen and goserelin. About 2 months after theoperation, she developed wound infection, accompaniedby neutropenic fever during chemotherapy. She underwentsplit skin grafting in September 2006 for wounddehiscence. In March 2007, she developed cellulitis of herright shin, meticillin-resistant Staphylococcal aureus(MRSA) bacteraemia, and focal abscess formation on hershin. Her condition healed following incision, debridementand 2 weeks of gentamicin and cefazolin. However, inApril 2007, a hot painful swelling recurred on her right shin.She had a CRP level of 13.9 mg/L and a WBC count of3900/mL with 68.3% neutrophils. In May 2007 shedeveloped diabetes, and started oral treatment. Also inMay 2007, she began empiric treatment with cefazolin andgentamicin. Bone scanning and x-ray of the right tibiashowed increased isotope uptake and an ill-definedosteolytic lesion with surrounding continuous periostealreaction, respectively, suggestive of chronic osteomyelitis.Retrospective analysis of x-rays from April 2007 alsoshowed osteolytic lesion at this site with mild periostealreaction.
