1. Influence of concurrent capecitabine based chemoradiotherapy with bevacizumab on the survival rate, late toxicity and health-related quality of life in locally advanced rectal cancer : a prospective phase II CRAB trialVaneja Velenik, Vesna Zadnik, Mirko Omejc, Jan Grosek, Mojca Tuta, 2020, original scientific article Abstract: Few studies reported early results on efficacy, toxicity of combined modality treatment for locally advanced rectal cancer (LARC) by adding bevacizumab to preoperative chemoradiotherapy, but long-term data on survival, and late complications are lacking. Further, none of the studies reported on the assessment of quality of life (QOL). Patients and methods. After more than 5 years of follow-up, we updated the results of our previous phase II trial in 61 patients with LARC treated with neoadjuvant capecitabine, radiotherapy and bevacizumab (CRAB study) before surgery and adjuvant chemotherapy. Secondary endpoints of updated analysis were local control (LC), disease free (DFS) and overall survival (OS), late toxicity and longitudinal health related QOL (before starting the treatment and one year after the treatment) with questionnaire EORTC QLQ-C30 and EORTC QLQ-CR38. Results. Median follow-up was 67 months. During the follow-up period, 16 patients (26.7%) died. The 5-year OS, DFS and LC rate were 72.2%, 70% and 92.4%. Patients with pathological positive nodes or pathological T3%4 tumors had significantly worse survival than patients with pathological negative nodes or T0%2 tumors. Nine patients (14.8%) developed grade % 3 late complications of combined modality treatment, first event 12 months and last 87 months after operation (median time 48 months). Based on EORTC QLQ-C30 scores one year after treatment there were no significant changes in global QOL and three symptoms (pain, insomnia and diarrhea), but physical and social functioning significantly decreased. Based on QLQ-CR38 scores body image scores significantly increase, problems with weight loss significantly decrease, but sexual dysfunction in men and chemotherapy side effects significantly increase. Conclusions. Patients with LARC and high risk factors, such as positive pathological lymph nodes and high pathological T stage, deserve more aggressive treatment in the light of improving long-term survival results. Patients after multimodality treatment should be given greater attention to the regulation of individual aspects of quality of life and the occurrence of late side effects.

4. Induction chemotherapy, chemoradiotherapy and consolidation chemotherapy in preoperative treatment of rectal cancer : long-term results of phase II OIGIT-01 TrialDanijela Golo, Jasna But-Hadžić, Franc Anderluh, Erik Brecelj, Ibrahim Edhemović, Ana Jeromen, Mirko Omejc, Irena Oblak, Ajra Šečerov Ermenc, Vaneja Velenik, 2018, original scientific article Abstract: The purpose of the study was to improve treatment efficacy for locally advanced rectal cancer (LARC) by shifting half of adjuvant chemotherapy preoperatively to one induction and two consolidation cycles. Patients and methods Between October 2011 and April 2013, 66 patients with LARC were treated with one induction chemotherapy cycle followed by chemoradiotherapy (CRT), two consolidation cycles, surgery and three adjuvant capecitabine cycles. Radiation doses were 50.4 Gy for T2-3 and 54 Gy for T4 tumours in 1.8 Gy daily fraction. The doses of concomitant and neo/adjuvant capecitabine were 825 mg/m2/12h and 1250mg/m2/12h, respectively. The primary endpoint was pathologic complete response (pCR). Results Forty-three (65.1%) patients were treated according to protocol. The compliance rates for induction, consolidation, and adjuvant chemotherapy were 98.5%, 93.8% and 87.3%, respectively. CRT was completed by 65/66 patients, with G % 3 non-hematologic toxicity at 13.6%. The rate of pCR (17.5%) was not increased, but N and the total-down staging rates were 77.7% and 79.3%, respectively. In a median follow-up of 55 months, we recorded one local relapse (LR) (1.6%). The 5-year disease-free survival (DFS) and overall survival (OS) rates were 64.0% (95% CI 63.89%64.11) and 69.5% (95% CI 69.39%69.61), respectively. Conclusions In LARC preoperative treatment intensification with capecitabine before and after radiotherapy is well tolerated, with a high compliance rate and acceptable toxicity. Though it does not improve the local effect, it achieves a high LR rate, DFS, and OS.
