Verteporfin (VP) was first used in Photodynamic therapy, where a non-thermal laser light (689 nm) in the presence of oxygen activates the drug to produce highly reactive oxygen radicals, resulting in local cell and tissue damage. However, it has also been shown that Verteporfin can have non-photoactivated effects such as interference with the YAP-TEAD complex of the HIPPO pathway, resulting in growth inhibition of several neoplasias. More recently, it was proposed that, another non-light mediated effect of VP is the formation of cross-linked oligomers and high molecular weight protein complexes (HMWC) that are hypothesized to interfere with autophagy and cell growth...

Fertility preservation in breast cancer patients is an increasingly relevant topic. In the present paper we review available data on the mechanism of ovarian damage caused by anticancer agents currently used for the treatment of breast cancer. We also describe current methods to preserve fertility including oocytes or ovarian tissue freezing and administration of LH-RHa during chemotherapy. The aim of the paper is to provide clinical oncologists with an adequate knowledge of the subject to enable them to give a correct counselling to young women that must receive chemotherapy and want to increase their possibilities of maintaining fertility...

Breast cancer (BC) has been genetically profiled through large-scale genome analyses. However, the role and clinical implications of genetic alterations in metastatic BC (MBC) have not been evaluated. Therefore, we conducted whole-exome sequencing (WES) and RNA-Seq of 37 MBC samples and targeted deep sequencing of another 29 MBCs. We evaluated somatic mutations from WES and targeted sequencing and assessed gene expression and performed pathway analysis from RNA-Seq. In this analysis, PIK3CA was the most commonly mutated gene in estrogen receptor (ER)-positive BC, while in ER-negative BC, TP53 was the most commonly mutated gene (p = 0...

Purpose: We evaluated the effect of positive superficial and/or deep margin status on local recurrence (LR) in invasive breast cancer treated with breast-conserving surgery (BCS) followed by radiotherapy. Materials and Methods: In total, 3403 stage 1 and 2 invasive breast cancer patients treated with BCS followed by radiotherapy from January 2000 to December 2008 were included in this study. These patients were divided into 3 groups according to margin status: clear resection margin status for all sections (group 1, n = 3195); positive margin status in superficial and/or deep sections (group 2, n = 121); and positive peripheral parenchymal margin regardless of superficial and/or deep margin involvement (group 3, n = 87)...

BACKGROUND: Delayed nausea after chemotherapy remains a symptom of interest. Clinicians often provide additional and/or pro re nata (p.r.n.) antiemetics with guideline-consistent antiemetics in an attempt to achieve further symptom control. Whether the usage of additional and/or p.r.n. antiemetics provide added benefit remains as a question. OBJECTIVE: The purpose of this study was to determine the benefit of providing additional antiemetics and/or p.r.n. antiemetics with guideline-consistent antiemetics in the control of nausea, functioning, and quality of life (QOL)...

BACKGROUND: Young women with breast cancer (BC) have an increased risk of contralateral breast cancer (CBC) compared with older women. This may contribute to the rising rates of bilateral mastectomy (BM), but it is unclear if BM leads to improved outcomes. METHODS: A prospectively maintained database was reviewed. Patient and tumor characteristics, survival, and rate of CBC were compared in women age ≤40 years treated for unilateral Stage 1-3 BC from January 2000 through December 2013...

PURPOSE: While the inflammatory cytokine interleukin-18 (IL-18) is known to activate natural killer (NK) cells, its precise role in cancer is controversial. In this study, we investigated the role of tumor-derived IL-18 on peripheral blood NK cells in breast cancer patients. RESULTS: In breast cancer cell lines, IL-18 was expressed and secreted in the triple-negative breast cancer (TNBC) cell lines MDA-MB-231 and HCC-70 but not in MCF-7 cells. The immature and non-cytotoxic CD56dimCD16dim/- NK cell fraction was increased following co-culture with MDA-MB-231 cells, and this increase was not observed with tumor cells transfected with siRNA for IL-18 or in MCF-7 cells...

Galectin-1 is a β-galactoside binding protein secreted by many types of aggressive cancer cells. Although many studies have focused on the role of galectin-1 in cancer progression, relatively little attention has been paid to galectin-1 as an extracellular therapeutic target. To elucidate the molecular mechanisms underlying galectin-1-mediated cancer progression, we established galectin-1 knock-down cells via retroviral delivery of short hairpin RNA (shRNA) against galectin-1 in two triple-negative breast cancer (TNBC) cell lines, MDA-MB-231 and Hs578T...

Breast cancer is the most abundant cancer worldwide and a severe problem for women. Notably, breast cancer has a high mortality rate, mainly because of tumor progression and metastasis. Triple-negative breast cancer (TNBC) is highly progressive and lacks the expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Therefore, there are no established therapeutic targets against TNBC. In this study, we investigated whether the expression of human melanoma-associated antigen A2 (MAGEA2) is associated with TNBC...

BACKGROUND: Approximately 4% of women age 70 will develop breast cancer during the next ten years. Reconstruction has become a standard option for young women undergoing mastectomy for breast cancer, however may not be offered to older women due to the presence of co-morbidities. There is limited data on the outcomes of mastectomy with reconstruction in patient's ≥ 70. This study examines comorbidities and 30-day complication rates in patients ≥70 undergoing mastectomy for breast cancer...

BACKGROUND: Mastectomy with immediate breast reconstruction (IBR) is a surgical strategy in breast cancer when breast-conserving surgery is not an option. There is a lack of evidence showing an advantage of mastectomy plus IBR over mastectomy alone on health-related quality of life (QoL). METHODS: A large prospective multicentre survey, STIC-RMI (support of innovative and expensive techniques - immediate breast reconstruction), was undertaken to study the changes in QoL in patients treated by mastectomy with or without IBR...
