Normal T-cells express high levels of BCL2 protein, data regarding BCL2 expression status and its diagnostic utility in T-cell lymphoma is scarce. We evaluated BCL2 expression in a series of mature T-cell lymphoproliferations including indolent and more recently recognized entities (follicular helper T-cell (TFH) lymphomas). Sixty-six neoplastic bi...

Background:
Vitamin C is an essential water-soluble vitamin required for many redox reactions in our body and its deficiency causes scurvy, a well characterized disease with multiple hematological manifestations. Studies dating back to 1950's demonstrated that patients with myeloid neoplasms tend to have lower plasma levels of vitamin C than health...
Background:
The risk of severe COVID-19 is increased in patients (pts) with hematologic malignancies, with a reported risk of death of 34% (Vijenthira et al, 2020). The ASH-ASTCT COVID-19 vaccine guidelines indicate that certain immunocompromised patient populations could have an attenuated response to the SARS-CoV-2 vaccine. However, most SARS-CoV...
Patients with cancer are a vulnerable population during the COVID-19 pandemic due to underlying immunosuppression, pre-existing comorbidities, and poor nutrition. There is a lack of data describing the disease course of cancer patients with COVID-19 disease. Therefore, we analyzed data from cancer patients with COVID-19 who were admitted to our hos...

Objectives:
Most patients with pancreatic cancer have high symptom burden and poor outcomes. Palliative care (PC) can improve the quality of care through expert symptom management, although the optimal timing of PC referral is still poorly understood. We aimed to assess the association of early PC on health care utilization and charges of care for...
Central nervous system (CNS) tuberculosis is a rare manifestation of all tuberculosis presentations. The incidence of brain tuberculoma is increasing in developed countries due to HIV infection and immigration from tuberculosis-endemic countries. Symptoms and radiologic findings of CNS tuberculosis can be non-specific and lead to misdiagnosis or mi...
The World Health Organization nominated SARS-CoV-2 as the cause of the Coronavirus Disease 2019 (COVID-19) and has been granted as a pandemic. COVID-19 is an emerging threat due to the risk of microvascular, venous, and arterial thrombosis, thereby exacerbating organ injury and mortality. Although the exact mechanism of extensive thromboembolism an...

Background
Race and ethnic differences affect the disease characteristics and clinical outcomes in many tumors, including acute myeloid leukemia (Byrne et al. AJCO, 2011). While earlier population-based studies reported no significant impact of race on survival outcomes in myelodysplastic syndromes (MDS) (Ma et al. Cancer, 2007), this study had a l...
Background
Outcomes of older patients (pts) with acute myeloid leukemia (AML) ineligible for intensive chemotherapy (IC) remain poor with an overall survival (OS) of <12 months (mo). The combination of venetoclax (ven) and azacitidine (aza) for such newly diagnosed AML pts in the confirmatory VIALE-A trial demonstrated an improvement in OS compared...
Objectives:
Although cure rates for early stage anal squamous cell cancer (ASCC) are overall high, there may be racial disparities in receipt of treatment and outcome precluding favorable outcomes across all patient demographics. Therefore, the authors aimed to assess the time to treatment initiation and overall survival (OS) in Black and White pa...
