Abbreviations: AJCC = American Joint Committee on Cancer; c = clinical; CLL = chronic lymphocytic leukemia; CML = chronic myelogenous leukemia; ECOG = Eastern Cooperative Oncology Group; EQ SQ = equivalent square of radiation therapy field (cm); LN = lymph node; p = pathologic; PTV = planning target volume; RT = radiation therapy; SLNB = sentinel lymph node biopsy; WLE = wide local excision.

^∗N/A denotes “not available” due to radiation treatment at an outside institution.

^†WLE denotes surgical procedure performed in the recurrent setting after WLE and ipsilateral SLNB or neck dissection followed by observation in the initial setting.
