Treatment Monitoring of a Patient with Synchronous Metastatic Angiosarcoma and Breast Cancer Using ctDNA.

Angiosarcoma is a rare and aggressive type of soft-tissue sarcoma with high propensity to metastasize. For patients with metastatic angiosarcoma, prognosis is dismal and treatment options are limited. To improve the outcomes, identifying patients with poor treatment response at an earlier stage is imperative, enabling alternative therapy. Consequently, there is a need for improved methods and biomarkers for treatment monitoring. Quantification of circulating tumor-DNA (ctDNA) is a promising approach for patient-specific monitoring of treatment response. In this case report, we demonstrate that quantification of ctDNA using SiMSen-Seq was successfully utilized to monitor a patient with metastatic angiosarcoma. By quantifying ctDNA levels using 25 patient-specific mutations in blood plasma throughout surgery and palliative chemotherapy, we predicted the outcome and monitored the clinical response to treatment. This was accomplished despite the additional complexity of the patient having a synchronous breast cancer. The levels of ctDNA showed a superior correlation to the clinical outcome compared with the radiological evaluations. Our data propose a promising approach for personalized biomarker analysis to monitor treatment in angiosarcomas, with potential applicability to other cancers and for patients with synchronous malignancies.

Fear of COVID-19 among patients with prior SARS-CoV-2 infection: A cross-sectional study in Estonian family practices.

BACKGROUND: Fear of coronavirus disease (COVID-19) has been associated with significant health effects. OBJECTIVES: To assess COVID-19 fear and investigate factors associated with higher fear among COVID-19 survivors over 6 months after infection. METHODS: Cross-sectional study using multistage sampling (family practices within the highest 5th percentile of numbers of SARS-CoV-2 infected patients and random sample of patients within these practices) performed from March 15 to 17 July 2021. Adult patients with a laboratory-confirmed history of COVID-19 were recruited for a self-administered 79-item questionnaire including demographics, self-rated health, physical activity, COVID-19 characteristics, severity and the fear of COVID-19 Scale (FCV-19S). Comorbidity data were extracted from Estonian Health Insurance Fund. Logistic regression models were used to evaluate factors associated with COVID-19 fear. RESULTS: Of 341 participants included, 60% were women, 24.2% were hospitalised due to COVID-19 and 22.2% had long COVID, 143 (42%) participants reported high levels of fear (cut-off FCV-19S >17.8). Higher fear was associated with being female (aOR 2.12, 95% CI 1.14-3.95), age ≥61 years (aOR 3.23, 95% CI 1.28-8.16), two-member-households (aOR 3.70, 95% CI 1.40-9.77) physical inactivity 6 months prior to COVID-19 (aOR 3.53, 95% CI 1.26-9.95), and symptom severity during acute COVID-19. Long COVID was not associated with higher COVID-19 fear (aOR 1.82 95% CI 0.91-3.63). CONCLUSION: Almost half of participants reported COVID-19 fear more than 6 months after infection. Greater fear was associated with sociodemographic factors, physical activity prior to COVID-19 and COVID-19 symptom severity. There is a need to target this population to develop appropriate interventions.

Predictors of do-not-attempt-resuscitation decisions in patients with infratentorial or large supratentorial intracerebral hemorrhages and consequences thereafter: a register-based, longitudinal study in Sweden.

OBJECTIVES: Do-not-attempt-resuscitation (DNAR) decisions for patients with infratentorial or large supratentorial intracerebral hemorrhages (ICHs) pose clinical and ethical challenges. We aimed to investigate factors associated with DNAR decisions in patients with infratentorial or large (≥30 mL) supratentorial ICH, and differences in complications, treatment, and mortality. MATERIALS & METHODS: This longitudinal, observational study comprised all patients treated for ICH at three stroke units in Gothenburg, Sweden, between November 2014 and June 2019. Patients were identified in the local stroke register, and additional data were collected from medical records and national registries. Mortality rates were followed 1 year after incident ICHs. Factors associated with DNAR decisions, and one-year mortality were explored. RESULTS: Of 307 included patients, 164 received a DNAR decision. Most (75%) decisions were made within 24 h. DNAR decisions were associated with higher age, pre-stroke dependency, stroke severity, and intraventricular hemorrhage. Patients without DNAR decisions received thrombosis prophylaxis, oral antibiotics, and rehabilitative evaluations more frequently. The one-year survival probability was 0.16 (95% confidence interval [CI] 0.11-0.23) in patients with DNAR decisions, and 0.87 (95% CI 0.81-0.92) in patients without DNAR decision. DNAR decisions, higher age, stroke severity, hematoma volume, and comorbidities were associated with increased one-year mortality. Thrombosis prophylaxis and living alone were associated with a lower hazard. CONCLUSION: The majority of DNAR decisions for patients with infratentorial or large supratentorial ICH were made within 48 h. Higher age, pre-stroke dependency, high stroke severity, and intraventricular hemorrhage predicted receiving a DNAR decision. DNAR decisions were strongly associated with increased short- and long-term mortality.
