Taxanes are now routinely used in conjunction with radiation therapy (RT) as adjuvant therapy for breast cancer. Recent publications have reported several cases of radiation pneumonitis (RP) in patients receiving RT and taxane chemotherapy, thus raising concern as to the safety of this combination. To decrease the potential risk of RP, we sequenced RT after taxane chemotherapy with a target interval of 3-4 weeks in two consecutive institutional breast protocols. ⋯ The median time interval for all patients between the completion of chemotherapy and the initiation of RT was 34 days (range 5-70 days). At the latest follow-up, 2 patients were diagnosed with metastatic disease and 38 patients were without evidence of disease. Sequencing of RT after taxane therapy with a target interval of 3-4 weeks does not appear to result in increased pulmonary toxicity and is associated with good local control.

We present our results regarding the cosmetic outcome achieved and the rate of infection using the MammoSite breast brachytherapy applicator to treat patients with partial breast irradiation. In addition, factors associated with cosmetic outcome and infection are analyzed. The study population consisted of 30 patients with early stage breast cancer treated using the MammoSite device from October 28, 2002, to February 13, 2004. ⋯ Infection occurred in 13.3% of the patients (4/30). An excellent or good cosmetic outcome was achieved in 93.3% of patients and infection occurred in 13.3% of patients treated with the MammoSite breast brachytherapy applicator. Excellent cosmetic outcome was associated with a greater balloon-to-skin distance, lower maximal skin dose per fraction, and smaller mean balloon volume; however, the results did not reach statistical significance.

Management of ductal carcinoma in situ (DCIS) has been evolving and the majority of women are now being treated with breast-conserving surgery and radiation therapy (i.e. breast conservation therapy [BCT]). Controversies still exist regarding the histologic features and margin status that are associated with local recurrence. The goal of this study was to review our institution's experience in patients diagnosed with DCIS and treated with BCT to determine pathologic features that can predict local recurrence, with particular emphasis on the final surgical margin status. ⋯ A multivariate analysis showed that early age at diagnosis, positive margin status, and high nuclear grade were independently associated with local recurrence. The morphology and immunohistochemical stains of all nine recurrent DCIS were similar to those of the original DCIS. Breast conservation can be achieved with excellent local control by obtaining microscopically negative margins as strictly defined by DCIS not touching the inked surgical margins, and postoperative radiation that includes boost therapy to the tumor bed.
