Effect of FOLFOX6 chemotherapy on serum VEGF expression in advanced colorectal cancer patients

OBJECTIVE

To explore the effect of FOLFOX6 chemotherapy on serum vascular endothelial growth factor (VEGF) expression in advanced colorectal cancer patients.

METHODS

A retrospective analysis of 81 patients with advanced colorectal cancer who visited our hospital from March 2014 to February 2016 was performed. All the patients were treated with FOLFOX6 chemotherapy. On day 1, patients received oxaliplatin 100 mg/m2 ivgtt (2h), calcium folinate 200 mg/m2 ivgtt (2h), 5 fluorouracil 400 mg/m2 iv bolus and 5 fluorouracil 2500 mg/m2 ivgtt (5h). The treatment course was 2 weeks, and 4 treatment courses were required. The changes in the levels of VEGF and CRP and quality of life before and after 4 courses of chemotherapy were observed and therapeutic effects and adverse reactions after chemotherapy were evaluated.

RESULTS

After treatment, the total efficiency of chemotherapy was 82.72% (67/81) with 24 cases in complete remission, 25 cases in partial response, 18 cases in stable disease and 14 cases in progressive disease. The levels of CRP and VEGF after the treatment were significantly lower than those before treatment (5.69±0.77) mg/L vs. (7.99±1.36) mg/L; (443.26±21.55) pg/mL vs. (542.83±20.44) pg/mL] (P<0.05). The KPS grade after treatment was significantly higher than that before treatment (57.84±4.6) point vs. (50.99±3.73) point] (P<0.05). Among them, 3 cases developed a rash, 5 cases experienced hair loss, and 9 cases developed nausea and vomiting.

CONCLUSION

FOLFOX6 chemotherapy can decrease serum VEGF expression in patients with advanced colorectal cancer and enhance the curative effect with high safety, which is good for the improvement of patients' survival.

Effective preoperative abdominal incision planning on a patient with a history of repeated abdominal operations using a three-dimensional reconstruction technique: a case report

This case report describes the use of a three-dimensional reconstruction technique to plan the abdominal incision in order to avoid incision-related complications in a 53-year-old female patient who had had a cystic mass in the liver for 16 years and had undergone four previous surgeries. The patient presented with a recurrent cyst. The surgical team used three-dimensional reconstruction to model the liver mass, the area of abdominal wall weakness due to previous surgeries, bowel adhesions, skeletal structure and whole abdominal contour. The models were superimposed upon each other to reveal the relationship between the various features so that the optimum incision point could be selected so as to avoid the area of abdominal wall weakness, bowel adhesions and vital organs. The actual surgical incision was made based on the three-dimensional reconstruction models and the surgeon was able to avoid the area of abdominal wall weakness and bowel adhesions as planned. No incisional hernia and wound infection were observed postoperatively and the incision healed well. The three-dimensional reconstruction technique for preoperative surgical incision planning on patients with a history of multiple abdominal surgeries can minimize incision-related complications and achieve good therapeutic results.
