Despite great interest, two randomised controlled trials (RCTs) of cytoreductive nephrectomy in the tyrosine kinase inhibitor setting in metastatic renal cell carcinoma have either closed early (SURTIME) or are recruiting very slowly (CARMENA) after 7 yr. Challenges in RCT delivery in uro-oncologic surgery are many. Multiple steps are needed to ensure strong recruitment to trials addressing important urologic cancer questions. Feasibility/pilot studies are key stepping stones towards successful delivery of surgical RCTs.

Purpose/Objective: To determine if a weekly cone-beam CT (CBCT) is enough to evaluate the entire tumor inclusion and the reproducibility throughout the radiation course treatment in lung cancer. Materials and Methods: Thirty-six lung cancer patients were treated with image-guided radiotherapy (IGRT) on an Elekta Synergy Beam Modulator linear accelerator. The GTV included the tumor and the positive nodes in PET-CT and pathologic analysis. The PTV was configured with the GTV and a margin of 0.7 cm – 1 cm in all directions. In our protocol of lung cancer treatment, prior to each radiotherapy fraction we make one cone-beam CT every day on the first five days of treatment using automated softtissue registration. The positional errors of the reference image in relation to the acquired image (given in terms of translation movements) were obtained. No rotations were permitted. The average of these translational movements in the three axes (x, y, z) was calculated. This average was applied from the sixth day of treatment until the end. Weekly image guidance was registered resulting in at least 10 CBCT scans for each patient. The deviations in the three axes in every weekly CBCT with respect to the average were analyzed (Tx, Ty, Tz) Results: The graphics summarize the result of our analysis. In 29 patients (80.6%) the mean value of the difference between the positional errors compared to the average was: x = (0.19 ± 0.14) cm, y = (0.21 ± 0.14) cm, z = (0.27 ± 0.16) cm. All these values were less than 0.5cm and were considered correct for the suitable treatment of the patients. The shifts in the z axis showed more variability compared to the other axes mainly related to breathing movements. Nevertheless this z axis variability did not influence on the entire tumor inclusion and the set up reproducibility. In the other 7 patients (19.4%) we obtained a greater difference in either axes, and a CBCT more often than once a week was evaluated by the physician. Conclusions: Our preliminary results showed that in most lung cancer patients treated with IGRT, once an average is calculated after the first five days of treatment, a weekly cone-beam CT is enough to evaluate the entire tumor inclusion and the reproducibility throughout the radiation treatment.
