A 38-year-old woman with metastatic breast carcinoma reported seeing "halos and flashes" in her left eye. Funduscopic exam revealed an elevated mass in the choroid of the left globe consistent with metastasis. Subsequent (18)F-FDG PET/CT revealed focal uptake in the nasal aspect of the left choroid of the eye corresponding to the mass seen on the funduscopic exam. Through correlation with the PET/CT, the lesion was retrospectively identified on the MRI. (18)F-FDG PET/CT post-radiotherapy showed complete response and thus supports that this imaging modality can be used for diagnosis and monitoring response...

BACKGROUND: Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of epithelial cells which is confined within the basement membrane of the mammary ductal-lobular system. It is of interest to determine to what extent the potential to metastasize increases for DCIS patients when the basement membrane is breached (i.e. microinvasion is present). METHODS: We retrieved the records of 525,395 women who had either first primary DCIS or small (≤ 2.0 cm) node-negative invasive breast cancer in the Surveillance, Epidemiology and End Results (SEER) registries database (1990-2013)...

Radiotherapy has an important role in the comprehensive treatment of breast cancer. However, the clinical outcome of adjuvant radiotherapy may be limited due to intrinsic radioresistance, it is necessary to explore efficient radiosensitization methods that improve the clinical outcome of patients undergoing radiotherapy. The present study aimed to investigate whether the novel mechanistic target of rapamycin (mTOR) inhibitor Torin2 enhances the radiosensitivity of MCF‑7 breast cancer cells. A Cell Counting Kit‑8 (CCK‑8) assay was performed to measure the effect of Torin2 on cell proliferation, while clonogenic assays were employed to determine the effect of Torin2 in combination with radiation on the proliferation of MCF‑7 cells...

We describe a 44-year-old female with triple-negative breast cancer who developed skin erythaema, sclerosis and contracture of her entire right breast 15 months after completion of post-lumpectomy chemotherapy and radiotherapy, consistent with post-irradiation morphoea (PIM). PIM is a rare complication of breast irradiation that impairs a patient's quality of life. PIM is located usually at the radiation port or in the surrounding tissue. Clinically, PIM is misdiagnosed commonly as lymphoedema and cellulitis in the early inflammatory phase, and recurrent breast cancer, chronic radiodermatitis (CRD), radiation-induced fibrosis (RIF), post-irradiation pseudosclerodermatous panniculitis (PIPP), atypical vascular lesions (AVL) or angiosarcoma (AS) in the late burnout phase...

Pseudoxanthoma elasticum is a systemic metabolic disease presenting calcifications and progressive fragmentation of elastic fibers. Actually, no targeted therapies are available for the treatment; only prevention of complications is possible. Classically, pseudoxanthoma elasticum is a "benign" disease, without cancer association. Herein, we reported a singular association of pseudoxanthoma elasticum with breast carcinoma, describing the clinical management, in particular intra-operative treatment, focusing on intra-operative radiotherapy since no specific guidelines are available in literature...
