101 Background: In the US, minority patients are underrepresented in cancer clinical trials. This is due to multiple factors, including socioeconomic barriers, limited medical insurance coverage and restrictive clinical trial eligibility, e.g., ANC cutoff. For the latter, conservative ANC cutoff disadvantages Black patients. Two-in-three Black individuals have a Duffy-null phenotype, that is associated with lower ANC with 5% prevalence of ANC <1,500 cells/µl. To improve Black patient accrual to cancer clinical trials, lowering the ANC cutoff was proposed as a potential solution over a decade ago. Its implementation is not known. This study evaluates the ANC cutoff values as part of the eligibility criteria for cancer clinical trials. Methods: We accessed the Clinicaltrials.gov website on 5/25/2023 and obtained the ANC cutoff of cancer clinical trials conducted in the US. We included adult therapeutic trials in the phases of recruiting, not yet recruiting, enrolling by invitation, and active-not yet recruiting. Trials with drug interventions were selected. Those focusing on surgical, behavioral, nutritional and radiotherapeutic interventions were excluded. All ANC cutoff values were converted to “cells/µl” for analysis. Results: A total of 911 trials were evaluated, and 470 met the eligibility criteria. Of the 470 trials, 366 (78%) involved solid malignancies, and 104 (22%) involved hematologic malignancies. Hematologic trials have significantly lower ANC cutoffs compared to solid tumor trials with median ANC cutoff of 1,000 (range, 250-2000) vs. 1,500 (range 250-3,000); p=<0.001. In all, 323 trials (68.7%) required patients to have ANC >1,500, and 116 trials (24.6%), primarily hematologic, required patients to have ANC >1,000. For myeloma and prostate cancer, two cancers with higher incidence among Blacks, 12.9% and 86.4% of the trials require ANC >1,500, respectively. All genitourinary, breast, head & neck, sarcoma, lung, skin, and neuroendocrine tumor trials excluded patients with ANC <1,000. Conclusions: Most hematologic malignancy trials have a more liberal ANC cutoff allowing patients with ANC <1,500 to participate. However, solid tumor trials remain more conservative, with 4 in 5 trials requiring an ANC cutoff of >1,500. A strict ANC cutoff remains a barrier to minority accrual.[Table: see text]

Abstract Hepatocellular carcinoma (HCC) has emerged as a major cause of cancer deaths globally. The landscape of systemic therapy has recently changed, with six additional systemic agents either approved or awaiting approval for advanced stage HCC. While these agents have the potential to improve outcomes, a survival increase of 2–5 months remains poor and falls short of what has been achieved in many other solid tumor types. The roles of genomics, underlying cirrhosis, and optimal use of treatment strategies that include radiation, liver transplantation, and surgery remain unanswered. Here, we discuss new treatment opportunities, controversies, and future directions in managing HCC.
