How long should one wait before biopsying a persistently palpable mass of early stage nodular lymphocte predominant Hodgkin lymphoma (NLPHL) after radiation?
In other words, how long after radiation therapy do you expect the palpable mass to completely resolve?
Answer from: Radiation Oncologist at Academic Institution
There is no set time frame for biopsy. I will recommend a PET/CT 3 months post treatment before making a decision on biopsy . The sensitivity, specificity, PPV and NNP of PET in NLPHL is 99 - 100 % (Grellier et al. Eur. J. Nucl . Med. mol Imaging 2014 ).
