TUMOR, TUMORS
There were 37 patients that received a combination of both complete-Rx (for tumors of at least 65 cc) and partial-Rx (for tumors more than 65 cc) treatments, thus, 2 categories of response were defined. Of these 37 patients, 84% (31 patients) had a convergent response, which was defined as either response or stability of both complete-Rx and partial-Rx tumors. The remaining 16% (6 patients), demonstrated a divergent response, which was defined as irradiated tumors that do not meet the convergent criteria (e.g., a partial-Rx tumor progressed while a complete-Rx tumor responded or remained stable). Of note, 1 of the 6 patients with a divergent response had a partial-Rx tumor respond while a complete-Rx tumor progressed.
