Purpose: Radiation treatment plans undergo peer review during chart rounds, but changes to treatment volumes would require replanning. Our group implemented weekly head and neck cancer “volume rounds” to peer review all target volumes for head and neck cancer before radiation therapy (RT) planning and chart rounds. Methods and Materials: We analyzed modifications made to planning target volumes (PTVs) at volume rounds for consecutive nonproton head and neck cancer cases from May 2020 to May 2021. Nine head and neck radiation oncologists participated in weekly volume rounds during this time. Recommendations were categorized as no changes, minor changes, major changes, additional workup (eg, biopsy or imaging), and consultation or tumor board discussion needed before the start of RT. Minor changes to PTVs generally did not require a second review before treatment planning while major changes did. Results: PTVs for 511 cases involving 432 patients underwent peer review and 298 (58.3%) of these cases did not require any modifications before treatment planning. Minor and major changes were recommended in 75 (14.7%) and 86 (16.8%) cases, respectively. Forty-five (8.8%) cases were recommended to have additional workup and 23 (4.5%) required additional consultation with nonradiation surgeons or medical oncologists. Of the 45 cases that were recommended for additional workup, 40 underwent biopsy or imaging. Positive findings on imaging or biopsy occurred in 13 patients, leading to a significant change in management, including 4 patients who underwent additional surgery after positive findings before the start of RT. Conclusions: Prospective peer review during head and neck cancer volume rounds led to frequent minor and major alterations to PTVs. Significant changes in the overall treatment plan, such as additional surgery before start of RT, occurred in a minority of patients. © 2022 The Authors |
