Abstract : Background: Radiation plays a major role in the management of localized prostate cancer (CaP). There are limited studies reporting the quality of life (QOL) and toxicity with CaP tomotherapy.Materials and Methods: This is a single-institutional prospective observational study evaluating the acute toxicity and QOL of patients with CaP receiving tomotherapy from May 2018 to October 2019. Toxicity assessed using radiation therapy oncology group toxicity grading. QOL assessed using International Prostate Symptom Score (IPSS) and QOL score.Results: A total number of 74 patients received radiation therapy (RT), of which 25 had postoperative RT and 49 had radical RT. The median age was 71 years. During RT, 8 (10.8%) had Grade 2 gastrointestinal (GI) and 4 (5.4%) had Grade 2 genito urinary (GU) toxicities. At 3 months, 1 (1.4%) had Grade 2 GI, 1 (1.4%) had Grade 2 GU, and 1 (1.4%) had Grade 3 GU toxicities. At 6 months, 1 patient had Grade 2 GU and no Grade 2 GI toxicity noted. In postoperative RT Group, 2 (8%) Grade 2 GI and 1 (1.4%) Grade 2 genitourinary toxicity reported during radiation. At 3 months, 1 (1.4%) Grade 2 GI, 1 (1.4%) G2 GU, and 1 (1.4%) G3 GU toxicities noted. At 6 months, no ≥ Grade 2 noted. In radical RT group, during radiation 6 (12.2%) Grade 2 GI and 3 (6.1%) Grade 2 GU recorded. At 3 and 6 months, no ≥ Grade 2 GI/GU toxicity was recorded. No Grade 3/Grade 4 observed in radical RT group. One patient in radical RT and one in postoperative RT had severe IPSS symptom score. Results are comparable to reported studies.Conclusion: Our initial clinical experience with helical tomotherapy in CaP confirms lower rate of toxicities and no significant worsening of QOL with RT.
