Abstract: Objective: To assess the response of preoperative concomitant chemo-radiation with capecitabine in patientswith locally advanced rectal carcinoma.Study Design: A descriptive observational study.Place and Duration of Study: This study was conducted at the Department of Oncology, Nishtar Hospital,Multan, Pakistan from 5th November 2024 to 5th May 2025.Methods: A total of 100 patients aged 18-70 years old, diagnosed with stage 3 or 4 non-metastatic rectaladenocarcinoma, were included. Protracted radiotherapy at 50.4 Gray was delivered over 5.5 weeks, with 1.8Gray per session, five days a week. An 825 mg/m2 dose of Capecitabine was administered orally twice a daythrough the radiotherapy course, including weekends, along with the start of radiotherapy. Surgery wasperformed 4-6 weeks after the concurrent treatment and the technique was chosen according to the surgeon'sdiscretion. Adjuvant chemotherapy of four cycles of IV 5-FU (400 mg/m2) and leucovorin (20 mg/ m2) wasstarted four to six weeks postoperatively.Results: Frequent grade I and II toxicity included anemia (70%), abdominal pain (50%), proctitis (42%), andnausea (46%). Capecitabine treatment was stopped in 25 patients due to grade III and IV diarrhea (37%),abdominal pain (14%), and proctitis (33%), but it did not have a significant impact on compliance. Theradiotherapy compliance was 90% and 93% capecitabine dose was administered as the total dose. A pathologiccomplete response was reached in 8 patients (8%). Tumor downstaging was achieved in 55% of patients, andnodal down staging was observed in 50% of patients.Conclusion: Concurrent chemoradiotherapy with capecitabine is a safe and well-tolerated treatment inpatients with locally advanced rectal cancer. It has comparable efficacy to 5-FU chemotherapy and can be usedas an alternative to achieve similar outcomes. How to cite this: Nasir F, Bashir A, Hassan MJ, Jamil T.
