Abstract

Purpose: Soft tissue sarcomas (STS) account for 8% of all cancers in adolescents and young adults (AYAs). Metastatic STS contribute significantly to disease-related mortality in this age group; however, data are limited due to under-representation in clinical trials. Methods: AYAs aged 18-39 years, diagnosed with metastatic STS between 1990 and 2012, were identified from The Royal Marsden Hospital database. Outcomes of interest were clinical characteristics, treatment patterns, overall survival (OS), and prognostic factors. Results: Overall, 455 patients were included. Median age at diagnosis of metastatic STS was 33 years (interquartile range [IQR] 27-37 years). The most common histological subtypes were leiomyosarcoma (n = 68, 15%), synovial sarcoma (n = 68, 15%), Ewing sarcoma (n = 44, 10%), and rhabdomyosarcoma (n = 35, 8%). Treatments included systemic therapy (n = 395, 87%; median 2 lines [IQR 1-3]; clinical trial n = 93, 22%), radiotherapy (n = 297, 66%), and metastasectomy (n = 191, 43%). Median duration between last chemotherapy regimen and death was 4.6 months (IQR 2-10). Median OS was 19.2 months (95% confidence interval [CI] 15.8-22.2); 5-year OS was 16%. Of common subtypes, patients with rhabdomyosarcoma had t...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
