Background/Aim. Four dimensional (4DCT) simulation is a useful tool for motion assessment in lung cancer radiotherapy. Conventional Three dimensional (3D) - Free Breathing simulation is static, with limited motion information. The aim of this study was to compare clinically significant differences between the target volumes defined on 3D CT vs. 4D CT simulation and potential impact on the planning target volume (PTV). In addition, to quantify movements of primary tumour (GTV) during 4D CT simulation on three axis -Z-supero inferior (SI), X-mediolateral (ML), and Y-anteroposterior (AP). Methods. This retrospective study evaluated 20 lung cancer patients who underwent CT simulation for radical radiotherapy treatment. Free Breathing 3D CT and 4D CT simulation were acquired for each patient in accordance with our institutional protocol. Volumetric comparison radiation volumes defined on 3D CT vs. 4D CT simulation was done-Gross tumour volume GTV 3D vs. internal GTV- (iGTV 4D) and PTV 3D vs. iPTV 4D. Volumetric values expressed in cm3 and equivalent spherical diameter (ESD) expressed in cm were assessed. Comparison of GTV movement in the phase FB-GTV FB, phase 0-GTV0, phase 50-GTV 50, and phase Maximum intensity projection (MIP) -GTV MIP was made with GTV FB as the basic value. The evaluation was made in three axis. Results. Comparison volumetric values between GTV 3D vs. iGTV 4D was 63.15 vs.85.51 (p<0.001) respectively. iGTV 4D was significantly larger than GTV 3D (p<0.001). The mean value (ESD) PTV 3D vs.iPTV 4D was 8.44 vs. 7.82 (p<0.001) respectively, and mean value volume PTV 3D vs. iPTV 4D was 352.70 vs. 272.78 (p<0.001) respectively. PTV 3D was significantly larger than iPTV 4D (p<0.001). Statistically significant difference (p<0.05) was identified in the deviation related to Z axis between the upper and lower lobe. Conclusion. 4D CT simulation based delineation can reduce planning target volume compared to 3D simulation based radiation therapy and therefore, it is a prerequisite for high-quality and precise radiation therapy treatment.

Abstract Background Family caregivers of patients with cancer undergoing radiation therapy experience significant distress and challenges related to high symptom burden and complex care demands. This is particularly true for caregivers of patients with head and neck, esophageal, anal, rectal, and lung cancers, who are often receiving combined-modality treatment and may have tracheostomy tubes, gastrostomy tubes, or colostomies/ileostomies. This study aims to evaluate a simulation-based nursing intervention to provide information, support, and training to caregivers during radiation therapy. Methods This randomized controlled trial will include a sample of 180 patients and their family caregivers. Caregivers assigned to the control group will receive usual care and an informational booklet from the National Cancer Institute (NCI). Those in the intervention group will receive usual care, the NCI booklet, and three meetings with a nurse interventionist during radiation treatment followed by a booster call two weeks posttreatment. Intervention sessions focus on themes consistent with the trajectory of radiation therapy: the patient experience/needs, the caregiver experience and dyad communication, and transition to survivorship. Outcomes are measured at baseline, end of treatment (T2), and 4 (T3) and 20 (T4) weeks posttreatment, with the primary outcome being caregiver anxiety at T4. Discussion This trial is innovative in its use of simulation in a psychoeducational intervention for family caregivers. The intervention is administered at point-of-care and aimed at feasibility for integration into clinical practice. Patient quality of life and healthcare utilization measures will assess how providing support and training to the caregiver may impact patient outcomes. Trial registration The trial was registered on 08/14/2019 at ClinicalTrials.gov (identifier NCT04055948).
