Leuprolide acetate (LEU), also known as Lupron, is commonly used to treat prostate cancer in men. As a gonadotropin-releasing hormone (GnRH) receptor agonist, it initially stimulates the release of gonadal hormones, testosterone (T) and estradiol. This surge eventually suppresses these hormones, preventing the further growth and spread of cancer cells. Individuals receiving this treatment often report anxiety and cognitive changes, but LEU's effects on the neural mechanisms that are involved in anxiety during the trajectory of treatment are not well known...

Circulating tumor cell clusters (CTC clusters) are potent initiators of metastasis and potentially useful clinical markers for patients with cancer. Although there are numerous devices developed to isolate individual circulating tumor cells from blood, these devices are ineffective at capturing CTC clusters, incapable of separating clusters from single cells and/or cause cluster damage or dissociation during processing. The only device currently able to specifically isolate CTC clusters from single CTCs and blood cells relies on the batch immobilization of clusters onto micropillars which necessitates long residence times and causes damage to clusters during release...

BACKGROUND: Breast cancer radiotherapy increases the risk of heart failure (HF) with preserved ejection fraction (HFpEF). Cardiomyocytes are highly radio-resistant but radiation specifically affects coronary microvascular endothelial cells with subsequent microvascular inflammation and rarefaction. The effects of radiation on left ventricular (LV) diastolic function are poorly characterized. We hypothesized that cardiac radiation exposure may result in diastolic dysfunction without reduced EF...

Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden...

This study searched a rare and aggressive type of cancer in dogs and humans, the breast carcinosarcoma. Both clinical and pathological traits of mammary carcinosarcomas in dogs are similar to humans, such as infrequent occurrence, fast tumor growth, and unfavorable prognosis when compared to carcinomas. Other possible alterations include chromosomal abnormalities that can be useful for the identification of tumoral cells and diagnosis. The aim of this study was to compare the chromosomal features of peripheral lymphocytes and tumor cells in a mammary carcinosarcoma of a 14-year-old female Poodle...

Galectin-3 is a galectin with a unique flexible N-terminal tail (NT) connected to the conserved carbohydrate recognition domain (CRD). Galectin-3 is associated with tumor immune tolerance and exhibits an ability to induce T cell apoptosis. We used Jurkat, Jurkat E6-1 and CEM T-cell lines and human peripheral blood mononuclear cells (PBMCs) to investigate the specific roles of the CRD and NT in inducing T cell apoptosis. Galectin-3 triggered sustained extracellular signal-regulated kinase (ERK) phosphorylation that induced apoptosis...

Background and Aim: MDM4, a negative regulator of the p53 tumor suppression pathway, has been demonstrated to be overexpressed in a variety of human cancers. Research has revealed that the rs4245739 A>C polymorphism of MDM4 in the 3′-untranslated region makes it a miR-191 target site, leading to lower MDM4 expression. This study aimed to detect if the rs4245739 single nucleotide polymorphism (SNP) impacts on thyroid cancer (TC) development in Iranian-Azeri patients. Materials and Method: Blood samples were taken from 232 healthy controls and 130 TC patients of Iranian-Azeri ethnicity...

Intracranial metastasis from prostate cancer is rare. As treatment of castration-resistant prostate cancer improves, the incidence of men with intracranial metastasis from prostate cancer is increasing. Radiation therapy for treatment of intracranial metastasis from prostate cancer is systematically reviewed. A comprehensive review examining peer-reviewed, English language articles from 1990 to 2015 was performed on multiple databases, yielding 1274 articles. These articles were reviewed and selected for studies that met the following inclusion criteria: (1) patients with intracranial metastases from prostate cancer; (2) patients underwent radiation therapy as primary or adjuvant therapy; (3) the sample size of patients was larger than 2...

BACKGROUND: Permanent prostate brachytherapy (PPB) is an effective treatment choice for low and intermediate risk prostate cancer (PCa). However, the impact of PPB on tumor immune status is still poorly understood. This study aimed to assess the immune status in PCa patients before and at different time points after PPB (1, 3, 6, and 12 months). METHODS: Blood was collected from 32 patients with low and intermediate risk PCa and 12 healthy volunteers. The frequency of immunocompetent cells was identified by flow cytometry...

Cervical cancer usually presents in advanced stages and is treated with chemoradiation. About 15-20 % patients present with local recurrence after chemoradiation. Radical surgical resection is the only treatment modality offering long term survival benefit in recurrent cervical cancer. The most common surgical option for these patients is pelvic exenteration. Radical hysterectomy may be done for patients with a small centrally located recurrence in the cervix with no infiltration of adjacent structures. The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy and pelvic exenteration for recurrent cancer cervix...

Purpose: Lung cancer is strongly associated to tobacco smoking. However, global statistics estimate that in females the proportion of lung cancer cases that is unrelated to tobacco smoking reaches fifty percent, making questionable the etiology of the disease. Materials and Methods: A never-smoker female with primary EGFR/KRAS/ALK-negative squamous cell carcinoma of the lung and their normal sibs were subjected to a novel integrative "omic" approach using a pedigree-based model for discovering genetic factors leading to cancer in the absence of well-known environmental trigger...

Positron-emission-tomography (PET) combined with computed-tomography (CT) and prostate-specific-membrane-antigen (PSMA) ligands has gained significant interest for staging prostate cancer (PC). In this study, we propose two multimodal quantitative indices as imaging biomarker for the assessment of osseous tumour burden using (68)Ga-PSMA-PET/CT and present preliminary clinical data. We define two Bone-PET-Indices (BPI) that incorporate anatomical information from CT and functional information from (68)Ga-PSMA-PET: BPIVOL is the percental bone volume affected by tumour...

Evidence suggests an association between inflammation and depression, although findings are mixed. Focusing on core processes in depression may clarify associated biological underpinnings. Negative cognitive bias is a key component of depression, but has not been examined in relation to inflammation. Thus, we tested the hypothesis that elevated inflammatory markers would be associated with negative attentional bias in a sample of 91 breast cancer survivors. Participants were drawn from a larger study and provided blood samples for assessment of peripheral markers of inflammation and completed questionnaires and neuropsychological testing...
