Pretreatment MRI Radiomics Based Response Prediction Model in Locally Advanced Cervical Cancer.

The aim of this study was to create a radiomics model for Locally Advanced Cervical Cancer (LACC) patients to predict pathological complete response (pCR) after neoadjuvant chemoradiotherapy (NACRT) analysing T2-weighted 1.5 T magnetic resonance imaging (MRI) acquired before treatment start. Patients with LACC and an International Federation of Gynecology and Obstetrics stage from IB2 to IVA at diagnosis were retrospectively enrolled for this study. All patients underwent NACRT, followed by radical surgery; pCR-assessed on surgical specimen-was defined as absence of any residual tumour. Finally, 1889 features were extracted from MR images; features showing statistical significance in predicting pCR at the univariate analysis were selected following an iterative method, which was ad-hoc developed for this study. Based on this method, 15 different classifiers were trained considering the most significant features selected. Model selection was carried out using the area under the receiver operating characteristic curve (AUC) as target metrics. One hundred eighty-three patients from two institutions were analysed. The model, showing the highest performance with an AUC of 0.80, was the random forest method initialised with default parameters. Radiomics appeared to be a reliable tool in pCR prediction for LACC patients undergoing NACRT, supporting the identification of patient risk groups, which paves treatment pathways tailored according to the predicted outcome.

The Outcome of Primary Root Canal Treatment in Postirradiated Patients: A Case Series.

Osteoradionecrosis (ORN) of the jaw is considered the most severe long-term adverse effect that can occur in radiation therapy patients. Teeth extractions and dental diseases are the main risk factors for ORN in irradiated patients. The aim of this case series was to evaluate the outcome of primary root canal treatments performed on patients who underwent head and neck radiotherapy and to evaluate any ORN related to the endodontic treatment. In this case series, primary root canal therapies (absence of radiolucency) were performed on 10 teeth of 8 patients who underwent radiotherapy for head and neck cancers. Radiation doses to the periapical area were calculated using the radiotherapy planning computed tomographic scan. After a 277-day mean follow-up, all patients were asymptomatic, no teeth showed periapical radiolucency, and no ORN was observed. Even if a limitation of buccal opening occurred after radiotherapy and complicated the endodontic procedures, root canal therapy seemed to be safe and a valid alternative to tooth extraction.

Phase 2 trial of nonpegylated doxorubicin (Myocet) as second-line treatment in advanced or recurrent endometrial cancer.

BACKGROUND: Advanced or recurrent endometrial cancer is associated with a poor prognosis, and results obtained with systemic therapy are far from being impressive. Myocet is an interesting formulation of citrate conjugated doxorubicin encapsulated in nonpegylated liposomes. This phase 2 study was designed to evaluate the objective response rate and the toxicity profile of Myocet in women with advanced or recurrent endometrial cancer. METHODS: Patients with diagnosis of advanced or recurrent endometrial cancer failing 1 previous carboplatin-paclitaxel chemotherapy were enrolled. Myocet was administered at the dose of 60 mg/m intravenously on day 1 every 4 weeks. RESULTS: Eighteen patients were enrolled in our institution from September 2007 to January 2010. No complete or partial response was observed. Stable disease was registered in 5 patients (27.5%). Median time to progression was 9 weeks. Median time to death was 24 weeks. Grade 3/4 anemia was reported in 2 patients (11%). Grade 3/4 neutropenia was observed in 16.5% and 44% of patients, respectively. The major nonhematologic toxicities (grades 3/4) were fatigue (22%), nausea, and vomiting (5.5%). CONCLUSIONS: Myocet presents no activity, and only few stabilizations of disease of limited duration in this recurrent endometrial carcinoma population previously treated with platinum-taxane chemotherapy are reported.
