RadiOnCOVID: Multicentric Analysis of the Impact of COVID-19 on Patients Undergoing Radiation Therapy in Italy.

Methods And Materials: Patients with ongoing or planned anticancer treatment at 19 Italian Radiation Oncology centers were included in the study retrospectively from 3 February 2020 to 31 December 2020 and prospectively from 1 January 2021 to 31 May 2021. Anonymized data were processed through a specific website and database. Antineoplastic treatment characteristics and timing and outcomes of COVID-19 and its impact on radiotherapy or systemic therapy were described.

Pattern of care for re-irradiation in locally recurrent rectal cancer: a national survey on behalf of the AIRO gastrointestinal tumors study group.

Purpose: Radical resection (R0) represents the best curative treatment for local recurrence (LR) rectal cancer. Re-irradiation (re-RT) can increase the rate of R0 resection. Currently, there is a lack of guidelines on Re-RT for LR rectal cancer.

Correlation of Pre- and Post-radio-chemotherapy MRI Texture Features With Tumor Response in Rectal Cancer.

Background/aim: The present study aimed to investigate radiomics features derived from magnetic resonance imaging (MRI) in patients with locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy (CRT).

Patients And Methods: We retrospectively evaluated data of 53 patients (32 males, 21 females) with T3/T4 or N+ rectal cancer who underwent MRI before and after CRT. Twenty-seven texture radiomics features were extracted from regions of interest, delimiting the tumor on T2-weighted images.

Impact of temporalis muscle thickness in elderly patients with newly diagnosed glioblastoma treated with radio or radio-chemotherapy.

Background: There is an unmet need for new biomarkers able to predict both the outcomes of up-front therapy and the compliance of elderly patients diagnosed with glioblastoma. For this purpose, temporal muscle thickness is a promising tool to be investigated.

Methods: Data from 52 glioblastoma patients older than 65 years, treated with post-operative radio or radio-chemotherapy and referred to Pisa University Hospital, were retrieved.

Role of magnetic resonance imaging following postoperative radiotherapy in clinical decision-making of patients with high-grade glioma.

Objectives: The present study aims to investigate the role of the first magnetic resonances (MRI) following radio-chemotherapy (RT-CT) in patients diagnosed with high-grade glioma.

Methods: We retrospectively recorded radiological evaluations following RT-CT, symptoms related to disease progression (avoiding any sign due to radiotherapy or chemotherapy) and the change of therapeutic strategy.

Results: In March 2021, at data analysis, the data of 149 patients diagnosed with high-grade glioma and treated between May 2013 and July 2020 were retrieved for the present analysis.
