Myc Promoter-Binding Protein-1 (MBP-1) Is a Novel Potential Prognostic Marker in Invasive Ductal Breast Carcinoma

2010

BackgroundAlpha-enolase is a glycolytic enzyme that catalyses the formation of phosphoenolpyruvate in the cell cytoplasm. α-Enolase and the predominantly nuclear Myc promoter-binding protein-1 (MBP-1) originate from a single gene through the alternative use of translational starting sites. MBP-1 binds to the P2 c-myc promoter and competes with TATA-box binding protein (TBP) to suppress gene transcription. Although several studies have shown an antiproliferative effect of MBP-1 overexpression on several human cancer cells, to date detailed observations of α-enolase and MBP-1 relative expression in primary tumors versus normal tissues and their correlation with clinicopathological features ha…

(177)Lu-labelled macrocyclic bisphosphonates for targeting bone metastasis in cancer treatment.

2015

Background Metastatic bone lesion is a common syndrome of many cancer diseases in an advanced state. The major symptom is severe pain, spinal cord compression, and pathological fracture, associated with an obvious morbidity. Common treatments including systemic application of bisphosphonate drugs aim on pain reduction and on improving the quality of life of the patient. Particularly, patients with multiple metastatic lesions benefit from bone-targeting therapeutic radiopharmaceuticals. Agents utilizing beta-emitting radionuclides in routine clinical praxis are, for example, [89Sr]SrCl2 and [153Sm]Sm-EDTMP. No-carrier-added (n.c.a.) 177Lu is remarkably suitable for an application in this sco…

Diffusion-weighted MRI of colo-rectal liver metastases treated by new anti-angiogenetic chemotherapy

A case of squamocellular uterine cervix carcinoma metastatic to the skin with enterocutaneous fistula.

2006

Metastases to the skin complicated by enterocutaneous fistula are a rare event in gynecological malignancies. We present the case of a 70-year-old woman with uterine cervix carcinoma metastatic to the skin and treated with surgery and radiotherapy. The last relapse to the skin was complicated by the formation of an enterocutaneous fistula. This low-output fistula was treated with surgery and adequate supportive care. The treatment of enterocutaneous fistulas may be either invasive (surgical resection, surgical repair with corrective procedures or with myocutaneous flaps, colonic and/or urinary diversion, endoscopic treatments with metallic stents) or conservative (skin care and local disin…

The HERBA trial: a retrospective study on patients (pts) with HER2-positive (HER2+ve) breast cancer (BC) and brain metastases (BMs)

Current role of computed tomography-guided transthoracic needle biopsy of metastatic lung lesions.

2015

ABSTRACT  Aim: As part of the Catania symposium on lung metastasectomy we reviewed our practice of computed tomography (CT)-guided percutaneous transthoracic needle biopsy of pulmonary metastatic lesions with particular emphasis on diagnostic accuracy and nature of complications lesions. Materials & methods: 25 patients with metastatic lesions of the lung have been evaluated between May 2010 and February 2014. Inclusion criteria consisted of patients with histologically confirmed, metastatic disease of the lung, those receiving a CT-guided needle biopsy, were at least 18 years of age; and with adequate hepatic, renal and hematological function. We recorded also the size of the sampled …

Effect of bone loss on the fracture resistance of narrow dental implants after implantoplasty. An in vitro study

2021

Background Implantoplasty (IP) involves polishing of the exposed surface of implants affected by peri-implantitis (PI). A study was made to determine whether the degree of bone loss influences the fracture resistance of implants with or without IP. Material and Methods An in vitro study was carried out on 32 narrow (3.5 mm) dental implants with a rough surface and external hexagonal connection. Implantoplasty was performed in half of the implants of the sample. Both the IP and control implants were divided into two subgroups according to the amount of bone loss (3 mm or 7.5 mm). Standardized radiographic assessment of implant width was performed using specific software. The main outcome var…

The Role of Palliative Radiotherapy in the Treatment of Spinal Bone Metastases from Head and Neck Tumors-A Multicenter Analysis of a Rare Event.

2020

This retrospective multi-center analysis aimed to assess the clinical response and stabilizing effects of palliative radiotherapy (RT) for spinal bone metastases (SBM) in head and neck cancer (HNC), and to establish potential predictive factors for stability and overall survival (OS). Patients included in this analysis were treated at the University Hospitals of Mainz, Freiburg, and Heidelberg between 2001 and 2019. Clinical information was taken from the medical records. The stability of affected vertebral bodies was assessed according to the validated spine instability neoplastic score (SINS) based on CT-imaging before RT, as well as 3 and 6 months after RT. OS was quantified as the time …

Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options

2013

Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…

Diagnóstico de Metástasis Ováricas de un linfoma B diseminado mediante ecografía 3D

2018

RESUMEN La participación del aparato genitourinario en el contexto de la enfermedad hematológica maligna es bien conocida. No obstante, la afectación ovárica por linfomas es inusual, ya sea de novo o como manifestación tardía de linfoma diseminado. El objetivo de esta comunicación es exponer la aportación diagnóstica de la ecografía tridimensional (3D) en la detección de metástasis ováricas, cuando todavía algunas de las pruebas de imagen estándar como la tomografía computarizada (TAC) son normales. En este caso presentamos una paciente con linfoma B difuso de células grandes mediastínico de crecimiento rápido y diseminación precoz a aparato gastrointestinal y genitourinario. ABSTRACT Genit…
