Combined treatment of rectal cancer with moderate risk of tumor progression
OBJECTIVE: To increase the effectiveness of combined treatment in patients with rectal cancer and moderate risk of progression based on the concept of polyradiomodification (PRM).
MATERIAL AND METHODS: The study included 337 patients with rectal cancer and moderate risk of tumor progression. A short course of radiotherapy (cRT) (5x5 Gy) combined with several radiomodifiers (cRT+PRM) was performed in 147 (43.6%) patients. Other 190 (56.4%) patients underwent cRT. The following radio modifiers were used: three-time application of local microwave hyperthermia (Yacht-3 or Yacht-4 devices), two-time intrarectal delivery of a biopolymer composition with Metronidazole before the 3rd and 5th irradiation sessions and two-week oral administration of Capecitabine (Xeloda) at a daily dose of 2.0 g/m2. Surgery was performed in 4-6 weeks after radiotherapy.
RESULTS: CRT+PRM program increased 5-year relapse-free survival up to 81.3% compared to 60.3% after cRT alone (p=0.0003) due to significant reduction of the incidence of cancer recurrence from 8.4% to 0.7% (p=0.0013). More effective local growth control expanded the indications for sphincter-sparing surgery. These procedures were performed in 89.1% and 70.5% of patients, respectively (p=0.00001). In the cRT+PRM group, sphincter-sparing surgery reduced incidence of cancer recurrence from 13.7% to 0.8% (p=0.0110), distant metastases - from 23.9% to 13.7% (p=0.00349).
CONCLUSION: Radiomodification in neoadjuvant radiotherapy is justified in patients with moderate risk of tumor progression, improves long-term results and increases the incidence of sphincter-sparing surgery.
