The clinical utility of circulating human papillomavirus across squamous cell carcinomas.

Background And Purpose: The similarities in biology, treatment regimens and outcome between the different human papillomavirus (HPV) associated squamous cell carcinomas (SCCs) allow for extrapolation of results generated from one SC tumor type to another. In HPV associated cancers, HPV is integrated into the tumor genome and can consequently be detected in the circulating fragments of the tumor DNA. Thus, measurement of HPV in the plasma is a surrogate for circulating tumor DNA (ctDNA) and holds promise as a clinically relevant biomarker in HPV associated cancers.

Pelvic Insufficiency Fractures and Bone Pain after Radiation Therapy for Anal Cancer: Relation to Pelvic Bone Dose-Volume Parameters.

Purpose: Chemoradiation therapy is the primary treatment for anal cancer. Radiation therapy (RT) can weaken the pelvic bone structure, but the risk of pelvic insufficiency fractures (PIFs) and derived pain in anal cancer is not yet established. We determined the frequency of symptomatic PIFs after RT for anal cancer and related this to radiation dose to specific pelvic bone substructures.

One-Year Treatment-Related Side Effects and Quality of Life After Chemoradiotherapy in Squamous Cell Carcinoma of the Anus.

Purpose: Patient-reported outcome (PRO) and National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) data for patients with squamous cell carcinoma of the anus (SCCA) treated with modern radiation therapy (RT) are lacking. The primary aim of this study was to report bowel and bladder PRO and NCI-CTCAE for patients with SCCA 1 year after RT.

Methods And Materials: From 2015 to 2020, we included patients in a prospective Danish national study.

Reporting on circulating tumor DNA monitoring in metastatic cancer-From clinical validity to clinical utility.

This commentary attempts to discuss the required standardization of circulating tumor DNA (ctDNA) analyses and thereby improve the clinical validity of ctDNA monitoring in the metastatic setting of solid tumors.

The Clinical Value of Measuring Circulating HPV DNA during Chemo-Radiotherapy in Squamous Cell Carcinoma of the Anus.

Background And Purpose: Circulating tumor DNA (ctDNA) is investigated in various cancers. In squamous cell carcinoma of the anus (SCCA) infection with human papilloma virus (HPV) is found in around 90% of cases and here, plasma HPV (pHPV) can be used as ctDNA. Preliminary data have proved the ability to detect pHPV16 and -18 in SCCA.

targeting of miR-223 in experimental eosinophilic oesophagitis.

Objectives: Eosinophilic oesophagitis (EoE) is characterised by oesophageal inflammation, fibrosis and dysfunction. Micro (mi)-RNAs interfere with pro-inflammatory and pro-fibrotic transcriptional programs, and miR-223 was upregulated in oesophageal mucosal biopsy specimens from EoE patients. The therapeutic potential of modulating miR-223 expression has not been determined.

Measurement of circulating free DNA in squamous cell carcinoma of the anus and relation to risk factors and recurrence.

Background: Measuring circulating-free-deoxyribonucleic-acid (cfDNA) has created a new framework for personalized treatment in oncology. The aim of this study was to analyze the relation between cfDNA and risk factors and outcome in squamous cell carcinoma of the anus (SCCA).

Methods: Patients treated with radiotherapy for localized SCCA were included in Aarhus, Denmark from 2016 to 2019.

Prospective evaluation of acute toxicity and patient reported outcomes in anal cancer and plan optimization.

Background And Purpose: Chemoradiotherapy (CRT) is the standard therapy for localized anal cancer (AC), but this treatment is associated with substantial toxicity. However, there is a lack of prospectively collected toxicity and patient reported outcome (PRO) data from larger cohorts. The purpose was to prospectively collect and determine agreement between physician assessed toxicity (CTCAE) and PRO during and after CRT and to compare IMRT, VMAT and proton-based planning in a subgroup of patients.

A case series study of eighty-five chronic spontaneous urticaria patients referred to a tertiary care center.

Background: Chronic spontaneous urticaria is a debilitating disease for the patients and often considered by the doctors a very difficult disease to treat. In 2009 the European Academy of Allergy and Clinical Immunology/Global Allergy and Asthma European network/European Dermatology Forum/World Allergy Organization (EAACI/GA(2)LEN/EDF/WAO) published a revised version of the guidelines for the treatment of urticaria which included an algorithm for the treatment.

Objective: The objective of this study was to examine the clinical effect and the practical use of the algorithm.
