ABSTRACT
PURPOSE:
The aim of this study was to evaluate efficacy and safety of chronomodulated capecitabine administered according to a specific time schedule (Brunch Regimen Breakfast and Lunch) as a part of neoadjuvant chemoradiation therapy in patients with locally advanced rectal cancer.METHODS:
Eighty-five patients with stage II and III rectal cancer were included. Patients received capecitabine (1,650 mg/m(2) per day; 60% dose at 800 AM and 40% dose at 1200 noon) administered during pelvic radiation (total 50.4 Gy in 28 fractions, 1.8 Gy daily dose between 200 p.m. and 400 p.m.). After chemoradiotherapy, patients underwent surgery. The primary endpoints were pathological complete response (pCR) rate and toxicity.RESULTS:
In 17 patients (20%), total tumor regression was achieved according to Dworak pathological grading system. Grade III diarrhea occurred in nine patients (10.5%), while only one patient had grade 3 thrombocytopenia. Grade II or III proctitis were seen in nine (10.5%) subjects, and grade I or II cystitis in six (6.9%). Only three patients (3.3%) developed hand and foot syndrome (both grade I-II). There were no grade IV toxicities.CONCLUSIONS:
Brunch Regimen for locally advanced rectal cancer consisting of neoadjuvant chronomodulated capecitabine and concurrent radiation therapy is effective and well tolerated with good safety profile, particularly with regard to the occurrence of hand and foot syndrome, in patients with locally advanced rectal cancer.
