114. Pelvic bone marrow dosimetric parameters analysis relating to hematologic toxicity in gynecological tumors patients treated with volumetric modulated arc therapy

Purpose To test the hypothesis that the volume of pelvic bone marrow (PBM) receiving 10–20-30–40 Gy (V10-V20-V30-V40) and median dose is associated with hematologic toxicity (HT) in gynecological cancer patients treated with concurrent chemoradiotherapy. Methods and materials We analyzed 29 consecutive gynecological cancer patients (21 only RT and 8 with concurrent chemotherapy) and volumetric-modulated-arc radiation therapy at the Varese...
