The Influence of Danish Cancer Patient Pathways on Survival in Deep-Seated, High-Grade Soft-Tissue Sarcomas in the Extremities and Trunk Wall: A Retrospective Observational Study.

Background: Soft-tissue sarcomas (STSs) are rare and challenging to diagnose due to their heterogeneous presentation. In 2009, Denmark introduced the Cancer Patient Pathways for sarcomas (CPPs) to improve sarcoma treatment by streamlining diagnostic and therapeutic processes. The primary objective of this study is to evaluate the impact of the CPPs on the overall survival of patients with deep-seated, high-grade STSs, comparing outcomes from before and after CPP implementation.

Evaluation of Two Different Approaches for Selecting Patients for Postoperative Radiotherapy in Deep-Seated High-Grade Soft Tissue Sarcomas in the Extremities and Trunk Wall.

Two national sarcoma centers have had different approaches for selecting patients with grade 2-3 deep-seated soft tissue sarcomas (STS) for postoperative radiotherapy (RT). We evaluated potential differences in local recurrence in patients treated at the two centers. At Sarcoma Center 1 (SC1), RT was the standard treatment for all tumors except certain small tumors excised with a margin wider than 1 cm.

Clival chordomas and chondrosarcomas in Denmark-Outcomes in 33 patients following the national centralization of treatment in 2010.

Purpose: This 13-year consecutive case series aims to provide a comprehensive overview of all patients operated for clival chordomas and clival chondrosarcomas in Denmark since the centralization of treatment in 2010, comparing outcomes to international series.

Methods: This was a retrospective review of 33 patients with clival tumors, comprising 22 chordomas and 11 chondrosarcomas, who were treated at Copenhagen University Hospital between years 2010 and 2023. Data were collected from digital patient records and pathology reports.

Angiosarcomas are rare, highly malignant tumours of vascular origin. They present as fast growing, haematoma-like and diffuse lesions. In this case report, a 71-year-old woman presented with what was assessed as an abscess arising from a traumatic haematoma of the forehead.

The Prognostic Value of Plasma Small Extracellular Vesicles' Phenotype in Patients With Gastrointestinal Stromal Tumor.

Background/aim: For patients with local gastrointestinal stromal tumor (GIST), risk stratification is used to assess the prognosis and identify patients to offer adjuvant treatment. For patients with advanced or metastatic GIST, no such risk stratification exists. This study aimed to investigate the prognostic value of 31 different plasma small extracellular vesicles' (SEVs) surface proteins in GIST patients.

Toxicity management of regorafenib in patients with gastro-intestinal stromal tumour (GIST) in a tertiary cancer centre.

Background: Regorafenib is a multi-kinase inhibitor approved as third line treatment for metastatic GIST. Dose limiting toxicities are frequently seen and many patients require dose reductions. This study aimed to evaluate regorafenib toxicities and their management in a real-world GIST population.

Low-grade Fibromyxoid Sarcoma: Treatment Outcomes and Efficacy of Chemotherapy.

Background: Low-grade fibromyxoid sarcoma (LGFMS) is a rare sarcoma subtype with a generally indolent pattern of clinical behaviour, but treatments for advanced disease are limited.

Patients And Methods: A retrospective search of a prospectively maintained institutional database identified 102 patients treated from December 1994 to August 2018. We evaluated the outcome of patients and the efficacy and safety of non-surgical therapies in LGFMS.

The Role of Local Therapy in Multi-focal Epithelioid Haemangioendothelioma.

Background/aim: Epithelioid haemangioendothelioma (EHE) is a rare tumor with a wide spectrum of clinical behavior. There is no consensus on the role of local therapy in symptomatic, multi-focal disease.

Patients And Methods: A retrospective review of patients presenting to the Royal Marsden Hospital between January 2000 and December 2017 was conducted.

FDG PET/CT in cancer: comparison of actual use with literature-based recommendations.

Purpose: The Region of Southern Denmark (RSD), covering 1.2 of Denmark's 5.6 million inhabitants, established a task force to (1) retrieve literature evidence for the clinical use of positron emission tomography (PET)/CT and provide consequent recommendations and further to (2) compare the actual use of PET/CT in the RSD with these recommendations.

Risk of recurrence in patients with colon cancer stage II and III: a systematic review and meta-analysis of recent literature.

Background: Adjuvant chemotherapy is established routine therapy for colon cancer (CC) patients with radically resected stage III and 'high-risk' stage II disease. The decision on recommending adjuvant chemotherapy, however, is based on data from older patient cohorts not reflecting improvements in pre-operative staging, surgery, and pathological examination. The aim is to review the current risk of recurrence in stage II and III patients and second, to estimate the relative importance of routinely assessed clinico-pathological variables.

Positron emission tomography/computed tomography and biomarkers for early treatment response evaluation in metastatic colon cancer.

Background: Treatment options for metastatic colon cancer (mCC) are widening. We prospectively evaluated serial 2-deoxy-2-[18F]fluoro-d-glucose positron-emission tomography/computed tomography (PET/CT) and measurements of tissue inhibitor of metalloproteinases-1 (TIMP-1), carcinoembryonic antigen (CEA), and liberated domain I of urokinase plasminogen activator receptor (uPAR(I)) for early assessment of treatment response in mCC patients.

Methods: Thirty-three mCC patients scheduled for first-line chemotherapy with capecitabine and oxaliplatin (CAPOX) and bevacizumab participated; 27 were evaluated by PET/CT before treatment, after one and four treatment series.

Positron emission tomography/computed tomography for optimized colon cancer staging and follow up.

Objectives: Optimal management of colon cancer (CC) requires detailed assessment of extent of disease. This study prospectively investigates the diagnostic accuracy of 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography/computed tomography (PET/CT) for staging and detection of recurrence in primary CC.

Material And Methods: PET/CT for preoperative staging was performed in 66 prospectively included patients with primary CC.

Functional characterization of serotonin receptor subtypes in human duodenal secretion.

Serotonin (5-HT) stimulates ion secretion in the gastrointestinal tract and the sensitivity for 5-HT might be altered in dyspeptic patients infected with Helicobacter pylori. The purpose of the present study was to characterize the 5-HT-induced electrogenic ion transport in the duodenum of dyspeptic patients with or without Helicobacter pylori infection, and to determine the 5-HT receptor subtypes functionally involved. Biopsies from the second part of duodenum were obtained from 43 dyspeptic patients during routine endoscopy.

Effects of cyclooxygenase and lipoxygenase inhibition on basal- and serotonin-induced ion transport in rat colon.

The purpose of this study was to determine the effect of a selective cyclooxygenase (COX)-2 inhibitor as compared to non-selective COX and lipoxygenase (LOX) inhibitors in rat colon. Basal- and serotonin (5-hydroxytryptamine, 5-HT)-induced electrogenic ion transport (short circuit current, SCC), prostaglandin E2 (PGE2) release and histological characteristics were measured. Muscle-stripped mucosal sheets of the proximal and distal segment of rat colon were investigated by employing the Ussing chamber technique, radioimmunoassays for PGE2 and light microscopy examinations for control of tissue integrity.
