Prevention of radiation induced dermatitis in head and neck cancer patients using cryptomphalus aspersa secretion.

Introduction: Radiotherapy (RT) is a technique widely used in oncology, acquiring special prominence in head and neck cancer (HNC). RT of HNC may be associated with secondary effects including skin reaction, being dermatitis the most common radio-induced side effect during treatment.

Purpose: The use of a wide variety of agents is reported to handle skin toxicity.

Pembrolizumab autoimmune related diabetes: Moving forward, keep learning.

Immune checkpoint inhibitors (and more specifically programmed cell death 1/programmed cell death ligand 1 inhibitors as Pembrolizumab) initiated a revolution in the field of melanoma and have now expanded to several tumor subtypes and in increasingly broader clinical contexts, including the adjuvant and neoadjuvant setting, with potentially curable patients and prolonged survival. The side effects related to these drugs include a wide spectrum of manifestations, with endocrinological adverse events being some of the most frequent. Pembrolizumab-induced type 1 diabetes mellitus is an infrequent but potentially serious and not clearly reversible side effect that possesses characteristic clinical features and has high morbidity and mortality, with a chronic impact on quality of life.

Hypofractionated whole breast IMRT with HDR brachytherapy boost in early-stage breast cancer: Long-term results from a single-center.

Introduction/objectives: The addition of a boost to the lumpectomy bed after whole-breast (WB) radiotherapy plays a key role in the treatment of patients with breast cancer (BC). The clinical benefits of a boost with high-dose-rate brachytherapy (HDR-BT) after conventional fractionation is supported by a large body of evidence. However, few studies have described its outcomes after a hypofractionated scheme.

Prospective study of HDR brachytherapy (BT), external beam radiotherapy (EBRT) and androgen deprivation therapy (ADT): 10-years experience of an MRI-guided approach.

Objectives: To evaluate the predictive factors for biochemical failure and distant metastases in a prospective cohort of patients with localized prostate cancer treated with the combination of HDR BT and EBRT.

Methods And Materials: Patients with intermediate (IR) or high-risk (HR) prostate adenocarcinoma received a single fraction of HDR of 15 Gy combined with RT of 37.5 Gy in 15 fractions.

Clinical Usefulness of Prostate-specific Membrane Antigen-ligand Positron Emission Tomography/Computed Tomography for the Detection of Prostate Cancer Biochemical Recurrence after Primary Radiation Therapy in Patients with Prostate-specific Antigen Below the Phoenix Threshold: Systematic Review and Meta-analysis.

Aims: After primary radiotherapy, biochemical recurrence is defined according to the Phoenix criteria as a prostate-specific antigen (PSA) value >2 ng/ml relative to the nadir. Several studies have shown that prostate-specific membrane antigen (PSMA)-ligand positron emission tomography/computed tomography (PET/CT) can help in detecting recurrence in patients with low PSA values. This study aimed to assess the detection rate and patterns of PSMA-ligand PET/CT uptake in patients with suspected biochemical recurrence after primary radiotherapy and with PSA levels below the Phoenix threshold.

Hyaluronic Acid Spacer for Hypofractionated Prostate Radiation Therapy: A Randomized Clinical Trial.

Importance: Hypofractionated radiation therapy (RT) for prostate cancer has been associated with greater acute grade 2 gastrointestinal (GI) toxic effects compared with conventionally fractionated RT.

Objective: To evaluate whether a hyaluronic acid rectal spacer could (1) improve rectal dosimetry and (2) affect acute grade 2 or higher GI toxic effects for hypofractionated RT.

Design, Setting, And Participants: This randomized clinical trial was conducted from March 2020 to June 2021 among 12 centers within the US, Australia, and Spain, with a 6-month follow-up.

Oligometastatic Hormone-Sensitive Prostate Cancer. Why Radiotherapy?

Androgen deprivation therapy (ADT) has been considered for years the standard initial treatment for patients with metastatic prostate cancer (mPC). Recently published results support the use of taxanes, second-generation antiandrogens or radiotherapy to the primary tumor as part of the treatment in these patients, considering ADT alone as suboptimal. Metastasis-directed therapy (MDT) is used as part of the treatment for oligometastatic patients in different tumor types.

Radiochemotheraphy-induced oral mucositis: Ectoin solution as a new treatment.

Background: The current treatment for head and neck cancer involves radiotherapy, systemic therapy and surgery in a multidisciplinary approach. Unfortunately, cancer therapies can lead to local and systemic complications or side effects such as mucositis, which is the most common dose-dependent complication in the oral cavity and gastrointestinal tract. Mucositis can cause a considerably reduced quality of life in cancer patients already suffering from physical and psychological exhaustion.

COVID-19 pneumonia treated with ultra-low doses of radiotherapy (ULTRA-COVID study): a single institution report of two cases.

Introduction: Since the outbreak of coronavirus disease 2019 (COVID-19) pandemic, healthcare systems have focused their efforts into finding a treatment to avoid the fatal outcomes of severe acute respiratory syndrome due to coronavirus‑2 (SARS-CoV-2). Benefits and risks of systemic treatments remain unclear, with multiple clinical trials still ongoing. Radiotherapy could play a role in reducing the inflammatory response in the lungs and relieve life-threatening symptoms.

Spanish risk management framework across 17 radiation oncology centers during COVID-19 pandemic.

The COVID-19 pandemic has impacted our healthcare systems and the rapid introduction of new protocols that have been required to keep patients and workforce safe. In order to maintain activity with radiotherapy clinical assistance, we have implemented different measures in our centers from a patient and staff safety perspective.

Can positron emission tomography support the characterization of immune-mediated inner ear disease?

Introduction: To evaluate the utility of F-FDG PET/TC as an imaging tool for the characterization of immune-mediated inner ear disease (IMIED), providing measurements of the inner ear region activity as well as detecting possible involvement of other organs.

Material And Methods: The study included 28 patients with IMIED and 4 sex-matched and age-matched control subjects with no history of ear disease. Eighteen patients were considered to be suffering from primary IMIED and 10 patients from secondary.

Cement fragment from hip arthroplasty causing deep femoral artery pseudoaneurysm.

An 81-year-old woman who had undergone total hip arthroplasty 12 years earlier presented with a painful spontaneous hematoma in the proximal left thigh. A left hip radiograph showed a displaced cement fragment from the acetabular component of the hip prosthesis. Computed tomography confirmed an extruded cement fragment causing a large pseudoaneurysm of the deep femoral artery.
