PURPOSE The aim of this retrospective study is to evaluate patient profile, feasibility, and acute toxicity of RadioTherapy (RT) delivered by VERO® in the first 20 months of clinical activity. METHODS Inclusion criteria: 1) adult patients; 2) limited volume cancer (M0 or oligometastatic); 3) small extracranial lesions; 4) treatment between April 2012 and December 2013 and 5) written informed ...

Introduction It is estimated that prostate cancer will reach 66 thousand by the triennium 2020-2022 according to National Cancer Institute (INCA). After initial diagnosis and staging patient may undergo radical prostatectomy and/or curative radiotherapy. In patients with biochemical relapse (PSA >0.2 ng/ml) initially treated prostatectomy, salvage external radiotherapy indicated. The [ 68 Ga...

Purpose: Evaluation of the 18-fluorodeoxy-glucose positron emission tomography-computed tomography (18-FDGPET/ CT) for gross tumor volume (GTV) delineation in gastric cancer patients undergoing radiotherapy. Methods: In this study, 29 gastric cancer patients (17 unresectable and 7 inoperable) were initially enrolled for radical chemoradiotherapy (45Gy/25 fractions + chemotherapy based on 5 fluo...

conclusions pet/ct can provide diagnosis and more accurate staging, location of tumor with its capability in providing the anatomical and physiological information synchronizes. therefore pet/ct plays an important role in oncology. objectives in this paper, we evaluate application of pet/ct for improve oncologic imaging. methods the papers were searched in pubmed and scopus databases with the r...

Hafnium-Based Nanomaterials The clinical translation of hafnium oxide for cancer radiotherapy has aroused extensive interest on Hf-based nanomaterials biomedical application. In article number 2300341, Gan Tian, Wenyan Yin, and co-workers comprehensively summarize the recent advances in synthesis, computed tomography (CT)-involved diagnosis radiotherapy-related synergistic therapy nanomaterials...

PURPOSE This study evaluates the diagnostic accuracy of [F-18]-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) of the chest/upper abdomen compared to the generally performed scan from head to upper thighs, for staging and management of (suspected) lung cancer in patients with no history of malignancy or complaints outside the thorax. METHODS FDG-PET/CT scans o...

Neoadjuvant chemotherapy, when combined with radiotherapy, serves as an optional treatment for patients locally advanced sigmoid colon cancer and is usually performed in conjunction complete mesocolic excision. The substantial movement of surrounding organs cases frequently leads to toxicity normal tissues. present report details the case a 76‑year‑old man diagnosed cancer. Initially, using Tom...

Tumor Treating Fields (TTFields) are non-ionizing alternating electric fields that have anti-cancer properties. After the initial approval for use in patients with recurrent glioblastoma 2011 and newly diagnosed glioblastomas 2015, they now being tested those advanced lung cancer, ovarian carcinoma, pancreatic cancer. Unlike ionizing radiotherapy, TTFields non-linear propagation characteristics...

We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed. That revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. Additionally tracer activity ...

The purpose of this study is to evaluate the dosimetric accuracy of MRI-based treatment planning for prostate cancer using a commercial radiotherapy treatment planning system. Three-dimensional conformal plans for 15 prostate patients were generated using the AcQPlan system. For each patient, dose distributions were calculated using patient CT data with and without heterogeneity correction, and...
