Cracking the code of a correlate of protection against SARS-CoV-2 breakthrough infection in cancer patients.

The level of protection against SARS-CoV-2 breakthrough infections conferred by the presence of anti-S1 SARS-CoV-2 antibodies (IgGs) in cancer patients is still understudied. This work examines the existence of an anti-S1 immunoglobulin G (IgG) -based correlate of protection (CoP) established by prospectively collected observational data about breakthrough infections with different SARS-CoV-2 variants in a large cohort study with vaccinated cancer patients. 760 cancer patients were longitudinally followed-up, starting before first vaccination until six months after second booster.

Management of high-grade neuroendocrine neoplasms: impact of functional imaging.

Gastroenteropancreatic neuroendocrine neoplasms (GEP NEN) exhibit substantial biological heterogeneity, impacting clinical management and outcomes. In 2019, the WHO subdivided the grade 3 (G3) neuroendocrine neoplasms (NEN) characterised by Ki-67 > 20% into the well-differentiated G3 neuroendocrine tumour (NET) and G3 poorly differentiated neuroendocrine carcinoma (NEC) subgroups. Since this update, questions about the prognostic implications and best treatment strategies for NET G3 and NEC remain.

Long-term risk and characteristics of cerebrovascular events after upper body radiotherapy among childhood cancer survivors in the DCCSS-LATER cohort.

Cerebrovascular events (CVEs) are serious late adverse events among childhood cancer survivors. We estimated the incidence and risk factors of symptomatic CVEs and described the clinical characteristics among childhood cancer survivors after upper body radiotherapy. The Dutch Childhood Cancer Survivor Study LATER cohort study includes 5-year childhood cancer survivors diagnosed View Article and Find Full Text PDF

Long-term effects of the COVID-19 pandemic for patients with cancer.

Introduction: Long COVID is defined as the continuation of symptoms, unexplainable by alternative diagnosis, longer than four weeks after SARS-CoV-2 infection. These symptoms might hinder daily activities and overall well-being, ultimately impacting quality of life (QoL). Several studies have reported fatigue as the most common symptom, followed by dyspnoea, headache and myalgia.
