Adaptive response of osteoblasts grown on a titanium surface: morphology, cell proliferation and stress protein synthesis.

2005

Titanium is one of the most widely used biomaterials in orthopaedic, dental and trauma surgery. Superficial adhesion and cell proliferation represent the first steps of cell-biomaterial interactions. The efficacy of this early phase influences the subsequent ability to differentiate, and hence the knowledge of these cell activities is important for studying and improving the biocompatibility of biomaterials. The aim of this study was to test the adaptive ability of osteoblastic cells grown on titanium surfaces, including morphologic, proliferative and adaptative aspects.

Radiotherapy for the treatment of solitary plasmacytoma: 7-year outcomes by a mono-institutional experience.

2020

Objectives: Solitary plasmacytoma (SP) is characterized by a single mass of clonal plasma cells. Definitive RT can result in long-term local control of the SP. Due to the small number of patients and narrow range of doses, phase III randomized trials are lacking. The aim of this study is to further support the potential use of RT for the treatment of SP. Methods: Clinical data of all patients treated for SP at our Institution between 1992 and 2018 were reviewed. A total of 42 consecutive patients were analyzed. Results: The median follow-up was 84.8 months. Radiation dose did not differ significantly as a function of sex, type of SP (solitary bone plasmacytoma or as extramedullary plasmacyt…

A Multicenter Large Retrospective Database on the Personalization of Stereotactic Ablative Radiotherapy for Lung Metastases From Colon-Rectal Cancer:…

2021

PURPOSE/OBJECTIVE(S): stereotactic ablative radiotherapy (SABR) has been shown to increase survival rates in oligometastatic disease (OMD), but local control of colorectal metastases still remains poor. We aimed to identify potential predictive factors of SBRT response through a multicenter large retrospective database and to investigate how lung SBRT can impact on the progression to the polymetastatic disease (PMD). MATERIALS/METHODS: the study involved 22 centers, and was approved by the Ethical Committee (Prot. Negrar 2019-ZT). 1023 lung metastases treated with SBRT in 622 patients were reported. The median BED was 105 Gy10. Lesion diameter GTV, PTV volume, dose, fractionations, and site…
