CBCT in the diagnosis of osteonecrosis of the jaws

2013

Short Summary: ONJ is associated with bisphosphonates, and recently with antiangiogenic drugs. Another cause is radiotherapy. Few papers have previously investigated the value of CBCT in the diagnosis of ONJ. Purpose/Objectives: To describe the CBCT findings in the diagnosis of osteonecrosis of the jaws (ONJ) according to a new staging system of ONJ. Methods and Materials: 9 patients (5 women, 4 men, 54-76 yrs.) affected by ONJ were studied with a CBCT device (90 kV, 12.5 mA, 0.25 mm voxel size) in 2012-2013. 7/9 patients were treated with bisphosphonates (5 for bone metastasis, 2 for osteoporosis), 1/9 patient was treated with an antiangiogenic drug, 1/9 patient received radiotherapy. Pati…

Association between periodontal disease and prostate cancer: a systematic review and meta-analysis

2021

Background Periodontal disease is a chronic infectious disease caused by bacterial infection which may lead to various systematic diseases. Recently, increasing studies have explored the correlation of periodontal disease with the risk of prostate cancer. However, the findings were inconsistent. Hence, this study aims to investigate the association between periodontal disease and the risk of prostate cancer by a meta-analysis. Material and Methods PubMed, EMBASE, and Cochrane were searched for publications up to July 17, 2020. Cohort and case-control studies evaluating the risk of prostate cancer in patients with periodontal disease were included. A fixed or random-effect model was used to …

Efficacy of weekly low-dose chemotherapy in elderly women with advanced ovarian cancer: is there an antiangiogenic effect?

2006

13133 Background: In elderly patients decreased functionality of multiple organ systems may affect pharmacokinetics and pharmacodynamics of drugs. For this reason elderly cancer patients experience enhanced susceptibility to common chemotherapy-related adverse events. A way to prevent these effects could be metronomic chemotherapy, which is a variation of dose-dense therapy, with a cumulative dose significantly lower than maximum tolerated dose. Methods: 27 advanced ovarian cancer patients, median age 67 (range 60–86), received low dose weekly continuous chemotherapy until disease progression. All patients were treated with CBDCA AUC 2 mg/ml/min and Docetaxel 35 mg/sqm (adjusted according …

Role of Densitometric Criteria in Evaluation of Effectiveness of Antiangiogenic Therapies in Metastatic Colorectal Cancer: An Italian Clinical Experi…

2017

Background/Aim: To evaluate the role of densitometric criterion using the Choi Criteria in the assessment of the response to antiangiogenic treatments of metastatic colorectal cancer (mCRC) compared to the RECIST criteria. Patients and Methods: Fifty-four patients (mean age=50.6 years ) affected by advanced colorectal cancer and with hepatic and possibly peritoneal and pulmonary metastases, that can be treated with bevacizumab, were prospectively evaluated by computerized tomography (CT) scan. Metastases were also evaluated by CT in onedimensional form according to RECIST. Results: Results show that in 58% of analyzed cases, stable disease according to RECIST coincided with stable disease a…

Peri-implantitis-like medication-related osteonecrosis of the jaw: Clinical considerations and histological evaluation with confocal laser scanning m…

2021

Objective: In the recent years, an increasing number of peri-implant medication-related osteonecrosis of the jaw (PI-MRONJ) have been reported in literature, both in oncologic and osteoporotic patients. The aim of this study is to describe 19 cases of patients previously diagnosed as affected by peri-implantitis, who were treated for PI-MRONJ, with consideration on clinical and histopathological features. Materials and Methods: Patients included were affected by postmenopausal osteoporosis and were administered with different antiresorptive drugs. Due to the presence of clinical and radiological signs of peri-implantitis not healed after non-surgical periodontal treatment, they were referre…

Nintedanib in non-small cell lung cancer: from preclinical to approval

2015

Angiogenesis is a driving force of a tumor’s development. Targeting this process is an attractive option, as this is a feature shared by most of the solid tumors. A lot of antiangiogenic drugs have been developed following this path, including bevacizumab, sorafenib, sunitinib, vandetanib, ramucirumab, motesanib and many others. The latest drug of this class to be approved for patients with non-small cell lung cancer (NSCLC) was nintedanib, a triple angiokinase inhibitor. This molecule targets vascular endothelial growth factor (VEGF), platelet derived growth factor (PDGF) and fibroblast growth factor (FGF) pathways, avoiding the tumor’s switch to normal escape mechanisms. The pharmacokine…

Medication-Related Osteonecrosis of Jaws (MRONJ) Prevention and Diagnosis: Italian Consensus Update 2020

2020

The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference—held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) (20 October 2018, Ancona, Italy)—after the newest recommendations (2020) on MRONJ were published by two scientific societies (Italian Societies of Maxillofacial Surgery and Oral Pathology and Medicine, SI…

A Reassessment of the Therapeutic Potential of a Dopamine Receptor 2 Agonist (D2-AG) in Endometriosis by Comparison against a Standardized Antiangiog…

2021

Dopamine receptor 2 agonists (D2-ags) have been shown to reduce the size of tumors by targeting aberrant angiogenesis in pathological tissue. Because of this, the use of a D2-ag was inferred for endometriosis treatment. When assayed in mouse models however, D2-ags have been shown to cause a shift of the immature vessels towards a more mature phenotype but not a significant reduction in the amount of vascularization and size of lesions. These has raised concerns on whether the antiangiogenic effects of these compounds confer a therapeutic value for endometriosis. In the belief that antiangiogenic effects of D2-ags in endometriosis were masked due to non-optimal timing of pharmacological inte…

Review and update on drugs related to the development of osteonecrosis of the jaw

2019

Conflict of interest Conclusions of the working group on “New drugs related to the de-velopment of osteonecrosis of the jaw”. Spanish Society of Cranio-mandibular Dysfunction and Orofacial Pain and Spanish Society of Oral Medicine SEDCYDO-SEMO joint International Meeting: 30th SEDCYDO annual meeting & 15th SEMO Congress. Bilbao (Spain); June, 2019. [EN] Background: Medication-related osteonecrosis of the jaw (MRONJ) is a rare, but serious adverse effect of cer-tain drugs, of which bisphosphonates are the most widely known. This pathology is also associated with other medications such as the biologic antiresorptive agent, denosumab and some antiangiogenics such as sunitinib, bevacizumab or a…
