Definitive treatment of primary vaginal cancer with radiotherapy: multi-institutional retrospective study of the Korean Radiation Oncology Group (KROG 12-09).

Therefore, precise RT and careful observation are crucial in advanced vaginal cancer. In this study, the HPV status was not related to the survival outcome, but its further investigation is needed.
