Knowledge about the outcome determinants of severe acute respiratory syndrome coronavirus 2 infection in this population is essential for risk stratification and definition of appropriate management. Our objective was to evaluate prognostic factors for all-cause mortality in patients diagnosed with both cancer and COVID-19. METHODS All consecutive patients with cancer hospitalized at our institution with COVID-19 were included. Electronic medical records were reviewed for clinical and laboratory characteristics potentially associated with outcomes. RESULTS Five hundred seventy-six consecutive patients with cancer and COVID-19 were included in the present study. An overall in-hospital mortality rate of 49.3% was demonstrated. Clinical factors associated with increased risk of death because of COVID-19 were age over 65 years, Eastern Cooperative Oncology Group performance status > 0 zero, best supportive care, primary lung cancer, and the presence of lung metastases. Laboratory findings associated with a higher risk of unfavorable outcomes were neutrophilia, lymphopenia, and elevated levels of D-dimer, creatinine, C-reactive protein, or AST. CONCLUSION A high mortality rate in patients with cancer who were diagnosed with COVID-19 was demonstrated in the present study, emphasizing the need for close surveillance in this group of patients, especially in those with unfavorable prognostic characteristics.

- Neoadjuvant and adjuvant systemic treatment for hepatocellular carcinoma(2021) MATHIAS-MACHADO, Maria Cecilia; FONSECA, Leonardo G. daHepatocellular carcinoma (HCC) is a highly lethal malignancy, and few patients are candidates for curative-intended therapies. The mainstay of curative treatment in HCC is surgical resection, ablation, and transplantation. However, rates of recurrence are high, and there is no established approach to reduce the risk of recurrence and mortality. We discuss the available data and current landscape of (neo)adjuvant therapies aimed at decreasing recurrence risk and improving overall survival, including liver-directed therapies, tyrosine kinase inhibitors, and immunotherapy. Neoadjuvant strategies aimed at downstaging advanced HCC to enable local treatment and minimize the risk of recurrence using novel agents are also a topic of interest in current research. The improvements achieved in the advanced stages with immune-checkpoint inhibitors are priming ongoing trials that address potential future directions for both adjuvant and neoadjuvant strategies that may change the treatment paradigm of HCC in the near future.
- Biomarkers in Anal Cancer: Current Status in Diagnosis, Disease Progression and Therapeutic Strategies(2022) MATHIAS-MACHADO, Maria Cecilia; PEIXOTO, Renata D'Alpino; MONIZ, Camila Motta Venchiarutti; JACOME, Alexandre A.Squamous cell carcinoma of the anal canal (SCCA) is a rare neoplasm, but with rising incidence rates in the past few decades; it is etiologically linked with the human papillomavirus (HPV) infection and is especially prevalent in immunocompromised patients, mainly those infected with HIV. Fluoropyrimidine-based chemoradiotherapy remains the cornerstone of the treatment of non-metastatic disease, but the locally advanced disease still presents high rates of disease recurrence and systemic therapy of SCCA is an unmet clinical need. Despite sharing common molecular aspects with other HPV-related malignancies, such as cervical and head and neck cancers, SCCA presents specific epigenomic, genomic, and transcriptomic abnormalities, which suggest that genome-guided personalized therapies should be specifically designed for this disease. Actionable mutations are rare in SCCA and immune checkpoint inhibition has not yet been proven useful in an unselected population of patients. Therefore, advances in systemic therapy of SCCA will only be possible with the identification of predictive biomarkers and the subsequent development of targeted therapies or immunotherapeutic approaches that consider the unique tumor microenvironment and the intra- and inter-tumoral heterogeneity. In the present review, we address the molecular characterization of SCCA and discuss potential diagnostic, predictive and prognostic biomarkers of this complex and challenging disease.
