Abstract:
Objective To investigate the adjuvant therapeutic efficacy of three-dimensional conformal radiotherapy (3D-CRT) in treating patients who underwent surgical operation for biliary drainage.Methods Clinical data on 88 clinically diagnosed advanced pancreatic head carcinoma patients who received palliative biliary drainage surgery in Tanshan Gongren Hospital from Jan 2006 to Jan 2010 were retrospectively reviewed. The cases were categorized according to the treatment into control group ( n=34 ) , chemotherapy group ( n=23 ) and radiotherapy group ( n=31 ) . The patients in control group received no chemotherapy or radiotherapy after biliary drainage surgery.The patients in chemotherapy group received chemotherapy of 1 000 mg/m2 gemcitabine intravenous infusion on day 1 and day 8, 80 mg/m2 cisplatin intravenous infusion on day 1 for each treatment cycle.Each cycle lasted for 21 days and was repeated for 3 cycles at an interval of 7 days in a treatment course.Patients in radiotherapy group received 3D-CRT for 6 successive days followed by an interval on the 7th day.The treatment course was completed within 10~15 days with the total dosage of 3 000~4 800 cGy.The therapeutic effects and survival time were analyzed.Results The incidence of cancer associated pain was 52.9%, 39.1%and 9.7%in control group, chemotherapy group and radiotherapy group, respectively, which was significantly lower in radiotherapy than that in the other two groups (both P<0.05). The incidence of mild gastrointestinal symptoms was 8.8%, 73.9% and 16.1%, respectively, and that of bone marrow suppression was 0%, 82.6% and 9.7%, respectively, which were both significantly lower in radiotherapy group than in chemotherapy group (both P<0.05).The 1-year, 2-year and 3-year survival rate was 30.1%, 8.3%, 0% in control group, 35.3%, 14.8%, 0% in chemotherapy group and 46.4%, 21.1%, 3.6%in radiotherapy group, which in radiotherapy group was significantly higher than that in control group and chemotherapy group (all P<0.05).Conclusions 3D-CRT was a palliative strategy for advanced pancreatic head cancer, which could prolong the survival of patients.
