Should we customize PTV expansions for BMI? Daily cone beam computerized tomography to assess organ motion in postoperative endometrial and cervical cancer patients

“…15 Results in our study demonstrate certain patients with greater BMI may have greater daily shifts than 7 mm, which becomes important when daily CBCT is not routinely done. For obese patients, clinicians may need to consider daily imaging to verify positioning or expand their initial volumes to account for larger degrees of motion.…”

“…15 The guidelines established two separate clinical tumor volumes (CTVs) encompassing the vaginal cuff and parametrial tissue based on the bladder being full and empty. This volume was defined as the internal target volume (ITV).…”

Dosimetric benefits of intensity‐modulated radiotherapy and volumetric‐modulated arc therapy in the treatment of postoperative cervical cancer patients

“…The clinical target volume (CTV) was contoured according to the consensus guideline of the Radiation Therapy Oncology Group (RTOG) 0418 and its atlas on the RTOG website, which comprises a central vaginal CTV and a regional nodal CTV 20. The former included the proximal vagina and paravaginal tissues and the latter consisted of the common iliac, external and internal iliac, and presacral lymph nodes.…”

Safety of adjuvant intensity-modulated postoperative radiation therapy in endometrial cancer: Clinical data and dosimetric parameters according to the International Commission on Radiation Units (ICRU) 83 report

“…The contour of the pelvic nodes was defined according to the RTOG recommendations. 20 The PTV was fixed as a 0.5-cm expansion from the CTV. The rectum was drawn from the ano-rectal junction to the recto-sigmoid junction and from the upper rectum limit to the sigmoid until in the last slide on which it could be observed.…”
