After multivariable analysis, it was found that only African American children were at increased risk for waitlist mortality as compared to Caucasian children (adjusted hazard ratio = 1.25; P = 0.029). Post-HT, there were no disparities in early and midterm graft survival among groups, but African American children had increased numbers of rejection episodes compared to Caucasian and Hispanic children. African American children continue to experience increased waitlist mortality and have increased rejection episodes post-HT. Studies exploring barriers to health care access and implicit bias as reasons for these disparities need to be conducted.

In this review key clinical and pathological issues and informative molecular markers are being discussed 1) What is the preferred outcome parameter for curatively resected low grade NENs (carcinoid) e.g., overall survival or recurrence free interval? 2) Does the World Health Organization (WHO) classification combined with a Ki-67 proliferation index and molecular markers such as OTP and CD44 offer improved prognostication in low grade NENs? 3) What is the value of a typical/atypical carcinoid diagnosis on a biopsy specimen in local and metastatic disease? Diagnosis is difficult in biopsy specimens and recent observations of an increased mitotic rate in metastatic carcinoid from typical to atypical and high-grade NEN can further complicate diagnosis. 4) What is the (ir)relevance of morphologically separating large cell neuroendocrine carcinoma (LCNEC) small cell carc
