title: DNA polymerase chain reaction using fine needle aspiration biopsy smears to evaluate non-Hodgkin's lymphoma.
abstract: OBJECTIVE
  To apply polymerase chain reaction (PCR) analysis to the fine needle aspiration biopsy (FNAB) evaluation of lymphoid proliferations.
  
  
  METHODS
  We analyzed 37 consecutive archived FNAB malignant lymphoma specimens. Immunophenotypic data from the fine needle aspiration biopsy and excisional biopsy material was available for all specimens. PCR to identify monoclonal rearrangements of the immunoglobulin heavy chain gene, T-cell receptor and translocations involving the bcl-1 and bcl-2 genes was performed.
  
  
  RESULTS
  Seventy-eight percent of cases were detected by at least one of these assays. Where DNA analysis was performed on excisional biopsy material, 70% of the cases had identical results; no discordant results for the immunoglobulin heavy chain gene or T-cell receptor were found. In 23% of cases, after review of all available data, a discordant result was thought to be a consequence of a false negative result in DNA analysis of excisional biopsy material.
  
  
  CONCLUSIONS
  These findings indicate that PCR analysis of archived FNAB material, when necessary, provides useful information for diagnosis and staging of malignant non-Hodgkin's lymphomas.
