Male breast metastasis of ureteral cancer: a case report.

ABSTRACT: BACKGROUND:Breast metastasis from extra-mammary primary tumors is extremely rare. We recently experienced a rare case of a male breast metastasis of ureteral cancer and will provide a case report. CASE PRESENTATION:A 74-year-old man developed a ureteral cancer and underwent left nephroureterectomy with lymph node dissection. Although enlarged abdominal lymph nodes did not disappear completely after chemoradiotherapy, further extensive therapy was not performed. A mass just below the nipple of his right breast was acknowledged and he visited our department. Histological diagnosis was invasive carcinoma. It was initially diagnosed as a primary breast cancer, and he underwent a mastectomy and a sentinel lymph node biopsy. There was no intraductal lesion and the border of the tumor was clear. It was very similar to that of the previous ureteral cancer. The final diagnosis was breast metastasis of ureteral cancer rather than primary breast cancer. The postoperative course was good, but multiple lung metastases appeared 2 months after surgery. He eventually died of cancerous lymphangiopathy. CONCLUSION:It is important to accurately diagnose primary breast cancer or breast metastasis so as not to cause extra-invasion, but it was considered difficult to make a complete preoperative diagnosis.

Project description:Male breast cancer is a rare event, accounting for approximately 1% of all breast carcinomas. Although men with breast cancer had poorer survival when compared with women, data on prognosis principally derive from retrospective studies and from extrapolation of female breast cancer series. We reported the case of a very long survival patient.A caucasian 42-year-old man underwent radical mastectomy with axillary dissection for breast cancer in 1993. Pathologic stage was pT4pN0M0 infiltrating ductal carcinoma of right breast without lymph nodes metastases. Biological characterization was not available. He received adjuvant treatment with chemotherapy, six cycles of cyclophosphamide, methotrexate and fluorouracil, then endocrine therapy with tamoxifen for 5 years and complementary radiotherapy. Then he began clinical-instrumental follow up. In May 1996, a computed tomography scan showed multiple lung metastases. Hereafter he received several oncologic treatment including seven chemotherapy and five endocrine therapy lines with two re-challenge of endocrine therapy. In October 2007 further lung progression was showed and a biopsy was performed to characterize the disease. Histological examination confirmed breast cancer metastases, immunohistochemistry showed positive staining for estrogen receptor, negative for progesterone receptor and human epithelial growth factor receptor 2, proliferative index was 21%. In April 2013, bone disease progression was evident and he received radiant treatment to sacral spine. In May 2014 an off-label treatment with exemestane and everolimus combination was approved by Ethics Committee of the Marche Region. The patient received treatment for 3 months with evident clinical benefit to subcutaneous lesions of the chest wall that were not visible nor palpable on physical examination after 1 month of treatment.That is the case of long survival male breast cancer patient with luminal B subtype and no BRCA mutations. He achieved higher progression free survival with endocrine therapy creating the rationale for last line treatment with everolimus and exemestane combination. Attending conclusive results from ongoing studies, everolimus and exemestane should not be used routinely in male metastatic breast cancer patients, but taking into account for selected cases. At the best of our knowledge, this is the first case of male beast cancer treated with exemestane and everolimus combination.

Project description:Tumor-Infiltrating Lymphocytes (TILs) are composed by several immune subpopulations including NK, NKT, Tab, Tgd and B cells. Although some of these cells can have antitumoral activities, there is also a large number of cells which are not tumor-specific,known as bystander cells. These cells may not have a direct role in the antitumoral response but could lead to a modulation of the immune response after time. Recent studies have described fatal encephalitis and myocarditis in cancer patients after immune checkpoint therapies, in which EBV-specific T cells may be involved. Since EBV is able to infect B cells and epithelial cells, both present in the primary tumor site, the first events of these fatal responses could be a consequence of a dysregulation of the immune system in the tumor microenvironment, although this have not been deeply studied. Thus, the main objectives of this study are (i) to use EBV-transformed B cells from the tumor site as a model to study the tumor-infiltrating EBV+ B cells and (ii) to use these EBV-derived B cells to study the relationship with autologous T cells isolated from the tumor site. T cells from TILs have been isolated from a triple negative breast cancer patient before neoadjuvancy and were expanded directly from the biopsy. A Patient-Derived Xenograft (PDX) generated from the breast tumor, progressed into a lymphocytic neoplasm. EBVtransformed B cells were obtained from this PDX (PDX-derived B cells). T Cell Receptor high-throughput sequencing has been used to monitor the clonotypes present in the different samples. We have found 43 clonotypes infiltrating the PDX-562 tissue and 18 of them were also present in the human biopsy or in the biopsy-derived T cell cultures. 5 of these sequences were found in one of the biopsy-derived T cells analyzed. Thus, PDXderived B cells have been used as antigen presenting cells to expand these cells. Few clonotypes were obtained after expansions, although the analysis of the middle CDR3 have revealed a similar pattern with the 18 sequences from the PDX sample. Furthermore, peptides presented by HLA have been eluted from PDX-derived B cells, followed by MS analysis. Peptides obtained derived from 31 different proteins and >40% are cancerrelated in terms of expression.
