Likewise, radical hysterectomy negatively affects the sexual function and psychological health of patients, and the effects can persist for a long time (3). This study examined emotional adjustment, sexual functioning, quality of life and dissociative experiences in women with cervical cancer undergoing

Conclusion: IMPT has already proven the capability of sparing gastrointestinal and genitourinary organs without compromising target volume coverage. The approach of reducing myelosuppression by bone marrow sparing through IMPT has the potential to reduce treatment interruptions, improve patients’ quality of life, and reduce long-term treatment-related complications.
