Article Abstract
Background: The paradoxical reports about the prognostic value of the CD30 expression in extranodal NK/T-cell lymphoma (ENKTL) have restricted its further applications in clinical practice. To identify the common effects and the variation, we conducted this systematic review and meta-analysis.
Methods: PubMed, MEDLINE, Embase, and Web of Science were searched between January 1975 and 31 January 2017. The pooled hazard ratio was used to estimate the effect of the CD30 expression on overall survival. Bias was assessed by prespecified criteria referring to Reporting Recommendations for Tumor Marker Prognostic Studies and Newcastle-Ottawa Scale.
Results: Ten retrospective cohort studies with 310 patients are included. CD30 is associated with better overall survival significantly (HR 0.71, 95% CI 0.51 to 0.99, = 0%). A greater effect is observed among studies including participants predominant in regional involvement (HR 0.31, 95%CI 0.13 to 0.76, = 0%) compared with those in systemic involvement.
Conclusions: This study indicates that the CD30 expression is significantly associated with better prognosis in ENKTL, especially for patients with regional lymphoma involvement.

Expression of CD2, CD25 and/or CD30 in extracutaneous mast cells (MC) is a minor diagnostic criterion for systemic mastocytosis (SM) in the classification of the World Health Organization and International Consensus Classification. So far, it remains unknown whether expression of these antigens on MC is of prognostic significance in SM. We performed a retrospective multi-center study of patients with SM using the data set of the registry of the European Competence Network on Mastocytosis, including 5034 patients with various MC disorders.

The atypical expression of immune phenotypes in lymphoma is often associated with a poor prognosis and presents diagnostic challenges. The present study reports on a rare extranodal NK/T cell lymphoma. In addition to typical morphology and immunohistochemical characteristics, these tumors strongly express CD20 and CD30 and partially express CD15, which is associated with aggressive clinical behavior.

Brentuximab vedotin (BV) is an antibody-drug conjugate that combines the CD30 monoclonal antibody with the microtubule-disrupting agent, monomethyl auristatin E, which induces apoptosis in the tumor cell upon its release from the conjugate. The safety and efficacy of BV have been assessed in several studies in patients with T- and B-cell lymphomas. This article reviews the currently available data on the distribution of CD30 expression in T- and B-cell lymphomas, as well as the various levels of CD30 positivity cutoff used in the literature.

Purpose: Brentuximab vedotin (BV) is hypothesized to selectively deplete T regulatory cells (Tregs) that express CD30 and re-sensitize tumors to anti-(PD-1) therapy. This study evaluated responses to BV+pembrolizumab post PD-1 and explored corresponding biomarkers.
Methods: 55 patients with metastatic non-small cell lung cancer (NSCLC) and 58 with metastatic cutaneous melanoma received ≥1 dose of BV+pembrolizumab.

This article reports a patient with peripheral T cell lymphoma following treatment of Hodgkin lymphoma.The biopsy of cervical lymph node initially confirmed classic Hodgkin lymphoma,with Reed-Sternberg cells expressing CD30 and B cell-specific activator.After 2 years,the disease progressed and the patient was diagnosed with peripheral T-cell lymphoma (non-specific type) by lymph node biopsy,with the expression of CD3,CD4,and CD8.
