Abstract:
Objective To study the effect of preoperative selective arterial infusion chemotherapy (PSAIC) on large intestine cancer. Methods 63 patients with colorectal cancer underwent PSAIC with 5 fluorouracil,mitomycin and E adriamycin; the changes of clinical manifestation and pathology were observed and analyzed. Results (1)clinical manifestation:abdominalgia relieved in 18 patients and abdominal distention relieved in 16 patients.Improvement of hematochezia was found in 7 patients.In addition, of 13 patients with partial ileus, the clinical symptoms relieved in 9 patients. (2) pathology: there were karyopyknosis,karyorrhexis,coagulation and necrosis of cytoplasm in cancer cells. infiltration of inflammatory cells, edema and fibroelastosis in mesenchyne of cancer tissue. Proliferous intima and thrombus were also observed in the vessels. Most of these changes were moderate,and marked changes could also be seen in necrosis of cytoplasm and vessel intima proliferation. Conclusion PSAIC can control the focus of primary disease and the micrometastatic foci as well as improve the clinical symptoms, such as intestinal obstruction, and hematochezia, so PASIC is helpful to subsequent operation,and can improve the survival rate of patients with colorectal cancer.
