Overview
combination of these two findings on immunophenotyping of frozen section specimen cells and RT-PCR are confirmatory for Extranodal NK/T cell lymphoma:Detection of CD56 and EBER1 on tumor cells and EBV DNA (RT-PCR).Pathological examination of frozen section specimen may misled the NK/T cell diagnosis.Circulating cell free EBV DNA levels by RT-PCR is a diagnostic factor for EBV associated malignancies, Like extranodal NK/T cell lymphoma. Measuring both BamHI W DNA and LMP1 DNA is more useful as a prognosis predictor, these DNAs will decrease with treatment and increase with relapse. Recently, determination of negative immune checkpoints are considered as a drug target,in the case of extranodal NK/T cell lymphoma, PD-L1 will be expressed in the tumor, and patients with higher concentration of soluble PD-L1 showed worse prognosis.
Diagnostic Study of Choice
Study of choice
Investigations:
- Pathological examination of frozen section specimen may misled the NK/T cell diagnosis.[1]
- Circulating cell free EBV DNA levels by RT-PCR is a diagnostic factor for EBV associated malignancies[2], Like extranodal NK-T cell lymphoma.[3]
- Measuring both BamHI W DNA and LMP1 DNA is more useful as a prognosis predictor, these DNAs will decrease with treatment and increase with relapse.[4]
- Recently, determination of negative immune checkpoints are considered as a drug target[5],in the case of extranodal NK/T cell lymphoma, PD-L1 will be expressed in the tumor, and patients with higher concentration of soluble PD-L1 showed worse prognosis.[6]
Diagnostic results
The accompaniment of following findings on performing immunophenotyping on frozen section specimen and RT-PCR are confirmatory for Extranodal NK/T cell lymphoma:
