Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review.
2022
The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient’s fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnosti…
Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Prod…
2012
Abstract: In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid b…
Epidemiology, clinical manifestations, risk-reduction and treatment strategies of jaw osteonecrosis in cancer patients exposed to antiresorptive agen…
2014
Osteonecrosis of the jaws (ONJ) is an adverse side event of bisphosphonates and denosumab, antiresorptive agents that effectively reduce the incidence of skeletal-related events in patients with metastatic bone cancer and multiple myeloma. Available data suggest that 0–27.5% of individuals exposed to antiresorptive agents can develop ONJ. There is increasing evidence that avoidance of surgical trauma and infection to the jawbones can minimize the risk of ONJ, but there are still a significant number of individuals who develop ONJ in the absence of these risk factors. Bone necrosis is almost irreversible and there is no definitive cure for ONJ with the exclusion, in certain cases, of surgica…
Onset of MRONJ in Breast Cancer Patients after Switching from Low to High Dose of Bone Modifying Agents Due to Bone Metastases Development: A Single …
2022
Background: Medication-Related Osteonecrosis of the Jaw (MRONJ) is an adverse drug reaction mainly associated to bone modifying agents (BMAs). Breast cancer (BC) is the most frequent cancer worldwide. Its therapy can cause cancer treatment-induced bone loss (CTIBL), commonly treated with BMAs. The aims of this retrospective study are: to describe characteristics of BC patients under BMAs for CTIBL; to record any switch to high-dose BMAs; to assess MRONJ onset and to identify any factors associated with it. Patients: Authors included patients referred for MRONJ prevention to the Unit of Oral Medicine (University Hospital of Palermo). Results: Fourteen female BC patients under low-dose BMAs f…
In human osteosarcoma 3AB-OS cancer stem cells let-7d seems to have the dual function of oncogene/tumor-suppressor miRNA
2015
Introduction: Osteosarcoma (OS), an aggressive tumor a!ecting adolescents, shows therapy resistance and recurrence which can depend on cancer stem cells (CSCs), the source for tissue renewal and hold malignant potential; thus, OS treatment requires their eradication. Here, using 3AB-OS CSCs previously obtained from the OS-MG63 cells, we focused on the role of let-7d in managing stemness properties of 3AB-OS CSCs. Methods: 3AB-OS CSCs were stably transfected with pCDomH-plasmid, containing mir-let7-d, or empty vector as a control. Cell proliferation and viability were evaluated by EdU and Trypan blue assays, respectively. Sarcosphere and colony assays and wound healing and transwell invasion…
Clinical Significance of Tie-2-Expressing Monocytes/Macrophages and Angiopoietins in the Progression of Ovarian Cancer—State-of-the-Art
2022
Tumour growth and metastasis are specific to advanced stages of epithelial ovarian cancer (EOC). Tumour angiogenesis is an essential part of these processes. It is responsible for providing tumours with nutrients, metabolites, and cytokines and facilitates tumour and immune cell relocation. Destabilised vasculature, a distinctive feature of tumours, is also responsible for compromising drug delivery into the bulk. Angiogenesis is a complex process that largely depends on how the tumour microenvironment (TME) is composed and how a specific organ is formed. There are contrary reports on whether Tie-2-expressing monocytes/macrophages (TEMs) reported as the proangiogenic population of monocytes…

Oxidative stress, oxidative stress-based diseases and Mediterranean diet. Raman spectroscopy monitoring of skin carotenoids in healthy individuals an…
Abstract Evaluating the level of body antioxidants may reveal a more or less severe oxidative stress condition in either healthy people or subjects with pathologies, and can be suggestive for suitable dietary interventions to possibly affect it. In this work taking advantage from the Raman spectroscopic technology to measure the level of skin carotenoids in a simple and non-invasive manner, healthy people (age 15 to 70, n=155) and women who had surgery for breast cancer (BC) (age 38 to 76, n=71) have been screened to assess to what extent an increased intake of fruit and vegetables (healthy people and patients), associated with diets based on a classical Mediterranean style and that did not…
SICILIAN MANGO PEEL INDUCES CELLULAR STRESS ACCOMPANIED TO MITOCHONDRIAL DYSFUNCTION IN COLON CANCER CELLS
2021
Currently, cellular stresses as the oxidative, metabolic and genotoxic stress are considered the cause of many different human pathologies as neurodegenerative diseases (e.g.,Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis), alcoholic liver disease, chronic obstructive pulmonary disease, and also cancer. Although the role of cellular stress has been largely debated in cancer, nowadays some therapies aim to target the intracellular pro-oxidant/anti-oxidant balance triggering the tumor commitment to cell death. Therefore, it has become more necessary an improved understanding of cancer response to cellular stress that could be advantageous to develop cancer tailored therapies. In this…
