Extent of resection and role of adjuvant treatment in resected localized breast angiosarcoma

ConclusionsThe extent of surgery is not associated with improved survival in women with LBA, and patients may consider breast-conservation surgery. Adjuvant therapies are not associated with improved survival, with the exception of possible role of adjuvant chemotherapy in large primary tumors (5  cm or greater). Further clinical studies are needed to determine the impact of these treatments on local control, progression-free survival, and patients’ quality of life. Until then, the findings of our analysis will form basis for the multi-disciplinary discussion of management of women with L BA.

ConclusionLocal recurrences are mostly located within the subcutaneous tissue and the skin, assumed to result from unrecognized/subclinical tumour foci left behind after mastectomy, surgical implantation of tumour cells in the wound/scar and/or tumour emboli within the subcutaneous lymphatics. Pectoral muscle recurrences are less frequent and may be attributed to residual disease along the posterior surgical margin and/or lymphatic involvement.

We report a case of AH in a 49-year-old woman presenting as a mass in the breast, a site which, to the best of our knowledge, has not been previously documented in the English literature. Microscopic examination of the mass revealed a well-demarcated proliferation of anastomosing vascular spaces lined by bland endothelial cells, with focal hobnailing and scattered intravascular fibrin thrombi. No mitotic activity was observed and the Ki-67 proliferative index was low. These features were interpreted as AH, a lesion that may be difficult to distinguish from low-grade angiosarcoma or other benign vascular lesions of the brea...

ConclusionAlthough the data is limited, the early clinical results are promising. Further clinical trials are needed, especially in the setting of locally advanced and recurrent disease, to fully define the potential role of carbon ion radiation therapy in the treatment of breast cancer.

ConclusionTumor size and grade seem to be reliable predictors of survival in both PAS and SAS. Mastectomy does not seem to be adding any additional benefit to BCS. Adjuvant radiation therapy showed statistically significant RFS benefit, while adjuvant chemotherapy can be beneficial in high grade tumors.

Stephens PJ, Zhu VW, Ou SI, Lovly CM, Gounder M, Schrock AB, Ross JS, Miller VA, Klempner SJ, Ali SM Abstract PURPOSE: Amplifications of receptor tyrosine kinases (RTKS) are therapeutic targets in multiple tumor types (e.g. HER2 in breast cancer), and amplification of the chromosome 4 segment harboring the three RTKs KIT, PDGFRA, and KDR (4q12amp) may be similarly targetable. The presence of 4q12amp has been sporadically reported in small tumor specific series but a large-scale analysis is lacking. We assess the pan-cancer landscape of 4q12amp and provide early clinical support for the feasibility of targeting th...

A 72-year-old woman presented with 2-month history of “bruises” on the left breast. She was treated for a left breast cancer 6 years earlier. She previously had stage IA (cT1cN0M0) invasive ductal carcinoma that was estrogen receptor/progesterone receptor positive and Her2 negative. She underwent partial mastectomy and sentinel lymph node biopsy th at confirmed stage pT1cN0. In the setting of bilateral silicone breast implants, she received adjuvant partial breast irradiation to 36 Gy in 9 fractions twice daily, targeting the seroma with 1.5 to 2 cm margins.

This is a short clinical report depicting an exceptionally early presentation of radiation-induced angiosarcoma and overview of the literature. This case highlights the need for a high level of clinical suspicion in those patients presenting with unresolving cutaneous skin changes after radiotherapy for breast cancer. Breast-conserving therapy, comprising breast-conserving surgery and adjuvant radiotherapy, has largely replaced mastectomy in the treatment of early-stage breast carcinoma. Breast angiosarcoma is a rare but severe long-term complication associated with postoperative radiotherapy (Int J Radiat Oncol Biol Phys...

ConclusionThe preferred treatment is always aggressive surgical removal and, as our atypical clinical case suggests, neoadjuvant chemotherapy in very high doses is also needed. A biopsy of any suspicious breast skin lesion after radiotherapy is recommended. Despite the treatment challenges, our case provides enlightening details on the management of such a rare cancer even when faced with unplanned events which do not always allow for a textbook approach.
