Vinflunine in the treatment of relapsed metastatic urothelial cancer: A systematic review and meta-analysis of real-world series
2019
Background. Vinflunine (VFL) is approved in Europe as second-line treatment of metastatic urothelial cancer after failure of platinum-containing therapy. We performed a systematic review and meta-analysis of real-world data (RWD) to assess utilization, efficacy and safety of VFL. \ud \ud Methods. We performed a MEDLINE search for the period of 1/1/2000-31/8/2017. Full-length articles providing post-marketing RWD on VFL in patients failing previous chemotherapy were eligible. Interventional clinical trials were excluded. \ud \ud Results: Ten studies with 797 patients were identified. According to pooled REs analysis, overall response rate was 19%, most frequent, all-grade toxicities were fat…
Aggressive variants of prostate cancer – Are we ready to apply specific treatment right now?
2019
Recently, adoption of novel drugs for systemic treatment of metastatic prostate cancer has led to a striking improvement of response rate and survival in both hormone-sensitive and castration-resistant disease. In most cases, prostate cancer essentially depends on androgen receptor signaling axis, even in castration-resistant setting, and hence may be targeted by second generation hormonal therapy. However, a subset of patients bears androgen-independent cancer biology with a short-term response to hormonal treatment, early and extensive visceral metastases, low PSA levels and poor outcomes. Identification and specific management of these rapidly fatal malignancies is of an unmet medical ne…
Session 2: Are we ready for primary chemotherapy in rectal cancer: who, when, why?
2018
The potential of preoperative chemotherapy in rectal cancer is the subject of investigation in a number of global randomized trials. In this overview and expert discussion, Professor Cervantes summarizes the findings of numerous Phase II trials testing neoadjuvant chemotherapy. The crucial points in the next phase of trials include: patient selection, whether radiotherapy can be omitted altogether and whether chemotherapy can be used to augment the initial response to chemoradiotherapy. Finally, with the emergence of Magnetic Resonance Tumour Regression Grade a reliable method for assessing response after initial chemoradiotherapy, we ask if this can be used to drive the use of further sele…
Ibrutinib versus temsirolimus in patients with relapsed or refractory mantle-cell lymphoma : an international, randomised, open-label, phase 3 study
2016
Mantle-cell lymphoma is an aggressive B-cell lymphoma with a poor prognosis. Both ibrutinib and temsirolimus have shown single-agent activity in patients with relapsed or refractory mantle-cell lymphoma. We undertook a phase 3 study to assess the efficacy and safety of ibrutinib versus temsirolimus in relapsed or refractory mantle-cell lymphoma.This randomised, open-label, multicentre, phase 3 clinical trial enrolled patients with relapsed or refractory mantle-cell lymphoma confirmed by central pathology in 21 countries who had received one or more rituximab-containing treatments. Patients were stratified by previous therapy and simplified mantle-cell lymphoma international prognostic index…
CpG islands in MyD88 and ASC/PYCARD/TMS1 promoter regions are differentially methylated in head and neck squamous cell carcinoma and primary lung squ…
2021
Abstract Background Patients with head and neck squamous cell carcinoma (HNSCC) can develop lung squamous cell carcinoma (LuSCC), which could be the second primary tumor or HNSCC metastasis. Morphologically it is difficult to distinguish metastatic HNSCC from a second primary tumor which presents a significant diagnostic challenge. Differentiation of those two malignancies is important because the recommended treatments for metastatic HNSCC and primary LuSCC differ significantly. We investigated if the quantification of the promotor methylation status in HNSCC and LuSCC differs. Methods Primary HNSCC (N = 36) and LuSCC (N = 17) were included in this study. Methylation status in the ASC/TMS1…
Involvement of Bax and Bcl-2 in induction of apoptosis by essential oils of three Lebanese Salvia species in human prostate cancer cells
2018
Prostate cancer is one of the most common forms of cancer in men, and research to find more effective and less toxic drugs has become necessary. In the frame of our ongoing program on traditionally used Salvia species from the Mediterranean Area, here we report the biological activities of Salvia aurea, S. judaica and S. viscosa essential oils against human prostate cancer cells (DU-145). The cell viability was measured by 3(4,5-dimethyl-thiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) test and lactate dehydrogenase (LDH) release was used to quantify necrosis cell death. Genomic DNA, caspase-3 activity, expression of cleaved caspase-9, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X (Ba…
Downregulation of intratumoral expression of miR-205, miR-200c and miR-125b in primary human cutaneous melanomas predicts shorter survival
2018
AbstractWhile only 15–25 percent of melanoma patients develop distant metastasis and die, this disease is still responsible for the majority of skin cancer-related deaths. The availability of adjuvant therapies makes the selection of high-risk patients essential. We evaluated the intratumoral expression of ten miRNAs in primary melanomas in relation to its ability to predict melanoma survival. To this end, we correlated miRNA expression in 132 cryopreserved primary and metastatic tumors with clinicopathological factors and clinical outcome. We found sequential downregulation of intratumoral expression of miR-125b, miR-182, miR-200c and miR-205 over the full spectrum of melanoma progression.…
Activated Thyroid Hormone Promotes Differentiation and Chemotherapeutic Sensitization of Colorectal Cancer Stem Cells by Regulating Wnt and BMP4 Sign…
2016
Abstract Thyroid hormone is a pleiotropic factor that controls many cellular processes in multiple cell types such as cancer stem cells (CSC). Thyroid hormone concentrations in the blood are stable, but the action of the deiodinases (D2–D3) provides cell-specific regulation of thyroid hormone activity. Deregulation of deiodinase function and thyroid hormone status has been implicated in tumorigenesis. Therefore, we investigated the role of thyroid hormone metabolism and signaling in colorectal CSCs (CR-CSC), where deiodinases control cell division and chemosensitivity. We found that increased intracellular thyroid hormone concentration through D3 depletion induced cell differentiation and s…
