Excerpt
Cervical cancer is the second most common female malignant tumor in the world [
1], for which radiotherapy is currently one of the main treatment methods. Related surveys show that approximately 80% of cervical cancer patients receive radiotherapy at different stages [
2,
3]. Intensity modulated radiotherapy (IMRT) and volumetric modulated arc radiotherapy (VMAT) have become standard radiotherapy methods. Compared with 3-dimensional conformal radiotherapy (3D-CRT), the dose distribution formed by new technologies above using reverse optimization algorithms is highly consistent with the planned target area and has better uniformity[
4‐
7]. However, advanced technology also brings corresponding computational burden, which greatly increases the total planning time. According to statistics, it takes an average of approximately 4 h for radiotherapists to delineate the planning target volume (PTV) and organs at risk (OARs), and may even take longer for some complex diseases. After that, a radiotherapy plan meeting the treatment standards is formulated by radiation physicists, which takes approximately 10 h for each patient [
8,
9]. The large amount of time required for the treatment plan inevitably leads to delayed treatment, thereby affecting the quality of treatment and prognosis of patients [
