We report the case of a 52-year-old woman who had a history of recurrent melanoma on her right shoulder with axillary lymph node metastasis (BRAF V600K–mutated melanoma) and right-side breast-invasive ductal carcinoma (stage pT1b N0sn). One year later, she presented with a left-sided chest wall mass and enlarging left axillary lymph nodes. Needle core biopsies were obtained from both lesions, and histologic examination showed a poorly differentiated tumor with pleomorphic/anaplastic morphology and necrosis. The tumor cells were strongly immunoreactive for GATA-3 without expression of melanocytic markers (S100, Melan ...

Conclusions The recent, first randomized clinical trial demonstrated overall and progression free survival benefits after SBRT to oligometastatic disease which supports prior retrospective case series (6). The spine is a common site of metastatic bone disease, and as high quality data continue to mature, along with completion of additional randomized clinical trials, it is expected that utility of SBRT to the spine will increase in the future. Spine SBRT is unique due to the requirement of sharp dose falloff to prevent serious neurologic morbidity. With recent advances in radiotherapy planning, robotic patient positionin...

In this study, the immunohistochemistry results demonstrated that DEPDC1 was high-expressed in breast cancer tissues compared with the paired adjacent normal breast tissues, and its tendency at protein level was consistent with mRNA level from TCGA data. Moreover, DEPDC1 mRNA level revealed the strongest association with poor prognosis and development in breast cancer. In vitro assays showed that DEPDC1 overexpression resulted in significant promotion of proliferation by regulating cell cycle in MCF-7 cells, whilst an opposite effect was found in the MDA-MB-231 cells with DEPDC1 deletion. Notably, further investigation ind...

iot S Abstract Chemo- and radiotherapy are treatments very helpful to cure cancers but are also well known for adverse effects such as secondary cancers. Breast cancers following Hodgkin lymphoma have been relatively well studied. Breast cancers after radiotherapy covering or nearby breasts or nipples are usually carcinomas or secondary sarcomas. Among the big cohort of patients treated for breast carcinomas, breast lymphomas developed in the same area are not usual. Nevertheless, published studies described a significant increased risk of non-Hodgkin lymphoma after initial radiotherapy for a solid cancer. Here, w...

In January, 2018, Academic Press published my bookPrecision Medicine and the Reinvention of Human Disease. This book has an excellent " look inside " at itsGoogle book site, which includes the Table of Contents. In addition, I thought it might be helpful to see the topics listed in the Book's index.

This study shows that embryonal cancer was the most common malignancy in patients aged 0 to 14, while carcinoma of the breast and soft tissue sarcoma were the two most common cancers in patients from 5 to 30 years-old.

Purpose: Phyllodes tumours are rare fibroepithelial malignancies graded depending on stromal component as benign, borderline and malignant [1]. Malignant phyllodes are highly aggressive and because of their clinical behaviour and prognosis should be treated as primary breast sarcomas rather than infiltrating ductal carcinomas [2]. Treatment principles are based on retrospective series and case reports. Surgery is the main treatment, aiming for surgical margin>1 cm (based on NCCN guidelines) with adjuvant RT considered [3].

Authors: Nalwa A, Nath D, Suri V, Jamaluddin MA, Srivastava A Abstract Myeloid sarcoma (MS) is an extramedullary solid neoplasm of immature myeloid cells. These tumours usually develop in concurrence with or following acute leukemia. The breast is an uncommon site for presentation of this tumour, where it is often misdiagnosed as lymphoma or carcinoma.A 33- year-old female presented with a right breast lump in a private hospital, which was diagnosed as ductal carcinoma on lumpectomy. Subsequently she developed a lump in the left breast and a similar diagnosis of carcinoma was made on biopsy. A left mastectomy was p...

In this study, we immunohistochemically evaluated 5229 different tumors for nuclear brachyury expression using a new rabbit monoclonal antibody and automated immunostaining (Leica Bond Max). Only nuclear labeling was scored, and antibody dilution of 1:2000 was used. In normal tissues, only rare cells in seminiferous tubules were labeled; all other organs were negative. All chordomas (75/76), except a sarcomatous one, were positive, whereas chondrosarcomas were negative. Among epithelial tumors, positivity was often detected in embryonal carcinoma (74%) and seminoma (45%). Pulmonary small cell carcinoma was often positive (...
