Targeting Phosphatases and Kinases: How to Checkmate Cancer
Metastatic disease represents the major cause of death in oncologic patients worldwide. Accumulating evidence have highlighted the relevance of a small population of cancer cells, named cancer stem cells (CSCs), in the resistance to therapies, as well as cancer recurrence and metastasis. Standard anti-cancer treatments are not always conclusively curative, posing an urgent need to discover new targets for an effective therapy. Kinases and phosphatases are implicated in many cellular processes, such as proliferation, differentiation and oncogenic transformation. These proteins are crucial regulators of intracellular signaling pathways mediating multiple cellular activities. Therefore, altera…
Is G8 geriatric assessment tool useful in managing elderly patients with metastatic pancreatic carcinoma?
Abstract Aim This paper aims to analyze the usefulness of the G8 geriatric oncology questionnaire in patients with advanced/metastatic pancreatic adenocarcinoma (aPAC) and its possible association with different clinical outcomes. Methods Patients age > 70 years were screened with the G8 tool and treated with intravenous nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2 for 3 consecutive weeks followed by one-week rest as prescribed after clinical evaluation by treating oncologists. Patient’s charts were evaluated for type and severity of toxicity, 2 cycle rate of completion, discontinuation rate, delays, dose reductions, and other outcomes response rates, progression-free, and overall su…
Cancer Stem Cell Biomarkers Predictive of Radiotherapy Response in Rectal Cancer: A Systematic Review
Background: Rectal cancer (RC) is one of the most commonly diagnosed and particularly challenging tumours to treat due to its location in the pelvis and close proximity to critical genitourinary organs. Radiotherapy (RT) is recognised as a key component of therapeutic strategy to treat RC, promoting the downsizing and downstaging of large RCs in neoadjuvant settings, although its therapeutic effect is limited due to radioresistance. Evidence from experimental and clinical studies indicates that the likelihood of achieving local tumour control by RT depends on the complete eradication of cancer stem cells (CSC), a minority subset of tumour cells with stemness properties. Methods: A systemati…
Adipose stem cell niche reprograms the colorectal cancer stem cell metastatic machinery.
Obesity is a strong risk factor for cancer progression, posing obesity-related cancer as one of the leading causes of death. Nevertheless, the molecular mechanisms that endow cancer cells with metastatic properties in patients affected by obesity remain unexplored. Here, we show that IL-6 and HGF, secreted by tumor neighboring visceral adipose stromal cells (V-ASCs), expand the metastatic colorectal (CR) cancer cell compartment (CD44v6 + ), which in turn secretes neurotrophins such as NGF and NT-3, and recruits adipose stem cells within tumor mass. Visceral adipose-derived factors promote vasculogenesis and the onset of metastatic dissemination by activation of STAT3, which inhibits miR-200…
