Topotecan (TPT), a potent anticancer camptothecin analog, is well described for the treatment of ovarian cancer, but has also anticancer activity against small-cell and non-small-cell lung cancer, breast cancer, and acute leukemia. Various nanocarriers, including liposomes, have been exploited for targeted delivery of TPT. However, there are a number of challenges with TPT delivery using TPT liposomes (TLs), such as low encapsulation efficiency, physiological pH labile E ring (hydrolysis), accelerated blood clearance, multidrug resistance, and cancer metastases...

Metastases to the female genital tract from gastric cancer are rare, but they significantly worsen the prognosis of such patients. The potential routes for metastasis to the female genital tract from gastric cancer include hematogenous spread, lymphatic spread and surface implantation. The rate of lymphatic metastasis to the ovary from gastric cancer has been reported to be higher compared with that from colorectal cancer. Uterine or Fallopian tube metastases are usually secondary to ovarian metastases, which are typically identified prior to the detection of gastric cancer in half of all synchronous cases, with complaints of abdominal distention, pain, palpable mass, or abnormal uterine bleeding...

Primary peritoneal carcinoma (PPC) is a type of rare malignant epithelial tumor. Metastasis from PPC to breast has been rarely reported. PPC originates de novo from the peritoneal tissues rather than invasion or metastasis from adjacent or remote organs. PPCs have been implicated in many cases of carcinomas of unknown primary origin. It is similar to ovarian cancer (OvCa), because it shares the same common embryonic origin, the coelomic epithelium (mesodermal origin). The mechanism of oncogenesis remains elusive...

This study uncovers disease characteristics by long-term follow-up in Ashkenazi early onset breast cancer (EOBC) patients, carriers of founder BRCA1/2 mutations compared to non-carriers of such mutations. An archives-retrospective design was conducted to study the pathological and clinical characteristics of 149 Ashkenazi Jewish EOBC patients (<42 years) who were referred consecutively to the oncogenetic clinic by the oncology centre at Rambam HealthCare Campus, as from 1995, with a mean follow-up of 13...

OBJECTIVE: Ezrin and p130Cas are structural proteins with an important role in signaling pathways and have been shown to promote cancer dissemination. We previously reported on overexpression of both ezrin and p130Cas in breast carcinoma effusions compared to primary carcinomas. Since ovarian and breast carcinomas share the ability to disseminate by forming malignant effusions, we sought to study the role of these molecules in ovarian carcinoma (OC). METHODS: OC cell lines were cultured in two different 3-dimensional conditions, on alginate scaffolds and as spheroids, which served as models for solid tumor and malignant effusions, respectively...

Bone health is of increasing clinical importance throughout the clinical course of breast cancer. First, many breast cancer treatments have effects on reproductive hormones that are critical for bone health. This endocrine disturbance results in accelerated bone loss and an increased risk of fractures that can have a significant negative impact on cancer survivors. Second, the bone marrow microenvironment is intimately involved in the metastatic processes required for cancer dissemination, and may be modified by agents that influence bone cell physiology; there is now strong clinical trial evidence that the use of adjuvant bisphosphonates reduces metastasis to bone by one-third and reduces breast cancer mortality by one-sixth in postmenopausal or premenopausal women undergoing ovarian function suppression...

Dear Editor, Cutaneous metastases (CM) are detected in about 0.6-10.4% of patients with an internal malignancy (1-3). Excluding melanoma, breast and lung carcinomas are the main source of CM in women and men, respectively (1,4,5). CM can have different clinical features, and a diagnosis of CM is usually suspected before performing a biopsy. However, this can be a pitfall for clinicians when the clinical presentation is not the typical inflammatory nodule or mass. Herein we report 2 cases of cutaneous metastases of breast carcinoma, initially treated as a common skin infection...

BACKGROUND/AIM: Ovarian metastases from breast cancer present diagnostic and therapeutic challenges. We conducted a two-center retrospective study to analyze the characteristics and evolution of patients with histologically proven ovarian metastases from breast cancer. PATIENTS AND METHODS: The records of 28 patients were analyzed, taking into consideration clinical and biological characteristics of primary breast tumors and ovarian metastases. Moreover, the outcomes of patients after diagnosis of metastases were analyzed by comparing two patient groups defined by whether the surgical treatment of ovarian metastases was optimal (residual tumor <2 cm) or not (residual tumor >2 cm)...

Identification of dysregulated microRNAs (miRNAs) in prostate cancer is critical not only for diagnosis, but also differentiation between the aggressive and indolent forms of the disease. miR-9 was identified as an oncomiR through both miRNA panel RT-qPCR as well as high-throughput sequencing analysis of the human P69 prostate cell line as compared to its highly tumorigenic and metastatic subline M12, and found to be consistently upregulated in other prostate cell lines including DU-145 and PC3. While miR-9 has been characterized as dysregulated either as an oncomiR or tumour suppressor in a variety of other cancers including breast, ovarian, and nasopharyngeal carcinomas, it has not been previously evaluated and proven as an oncomiR in prostate cancer...

Recombinant human erythropoietin (rhEPO) is used in breast and ovarian cancer patients to alleviate cancer- and chemotherapy-related anemia. Some clinical trials have reported that rhEPO may adversely impact survival and increase the risk of thrombovascular events in patients with breast cancer but not with ovarian cancer. The latter may potentially benefit the most from rhEPO treatment due to the nephrotoxic and myelosuppresive effects of standard platinum-based chemotherapy used in ovarian cancer disease...

Bilateral breast cancer incidence is appreciated to be between 0.3 to 12% and is determined either by a hereditary load associated with chromosomal instability under the effect of environmental factors, or by the evolution in a particular hormonal context which gives biological aggressiveness. We present the case of a patient, aged 38 years, clinically, imagistic and bioptic diagnosed with left axillary lymph node metastases of breast carcinoma NST invasive G3, IHC-RE = 60%, RP = 30%, HER2neu = 2 +, Ki67 = 20%, in August 2013...

Encouraging results from recent clinical trials are revitalizing the field of oncolytic virotherapies. Human adenovirus type 5 (HAdV-C5/Ad5) is a common vector for its ease of manipulation, high production titers and capacity to transduce multiple cell types. However, effective clinical applications are hindered by poor tumor-selectivity and vector neutralization. We generated Ad5/kn48 by pseudotyping Ad5 with the fiber knob domain from the less seroprevalent HAdV-D48 (Ad48). The vector was shown to utilize coxsackie and adenovirus receptor (CAR) but not CD46 for cell entry...

Metastases to the breast from tumors other than breast carcinomas are extremely rare and represent only 0.2-1.3% of all diagnosed malignant breast tumors. Furthermore, while the most common sites for advanced ovarian cancer metastases are the liver, lung, and pleura, metastasis to the breast from a primary ovarian cancer is uncommon and has only been reported in 0.03-0.6% of all breast cancers. Here we describe a case report of a 50-year-old female patient with a rare case of breast metastases from an advanced ovarian cancer, presenting as inflammatory breast cancer...

BACKGROUND: Hepatic resection is standard treatment for liver metastases from colorectal and neuroendocrine cancers as well as primary biliary and hepatic carcinomas. The role of hepatic resection in patients with non-colorectal non-endocrine liver metastases (NCNELM) is less defined. Overall survival in this group of patients is poor with few patients surviving beyond two years, even with modern chemotherapy. METHODS: A prospective database of all liver resections performed by a single surgeon (KSH) from January 2007 to December 2014 was maintained...

The abnormal expansion of a ≥36 CAG unit tract in the Huntingtin gene (HTT) leads to Huntington's disease (HD), but has also been associated with cancer: the incidence of cancer is lower in HD patients than in age-matched controls, but HD-causing variants of HTT accelerate the progression of breast tumors and the development of metastases in mouse models of breast cancer. To investigate the relationship between HTT CAGs and cancer, data concerning 2407 women with BRCA1 or BRCA2 mutations that predispose to breast and ovarian cancers and 431 patients with breast cancer without family histories were studied; the size of the CAG expansions on both HTT alleles was determined in each subject...
