Abstract:
Purpose To explore the relationship between expression of PCNA and COX-2 in the early laryngeal cancer with negative surgical margins and the local recurrence of tumor. Methods Totally 63 patients with early laryngeal cancer were enrolled in this stud-y, CO2 laser surgery was adopted as treatment, the expression of PCNA and COX-2 was detected in the resected tumor tissue and surgi-cal margins, and the survival and tumor recurrence were also observed. Results The positive rate of the expression of PCNA and COX-2 in the 63 patients with early laryngeal cancer tumor tissues were 73. 02% and 71. 43%, while that in the cutting edge were 33. 33% and 30. 16%, respectively. The expression of PCNA and COX-2 in tumor tissue and cutting edge were of all positive in 41 cases and 13 cases, and the positive rate was 65. 08% and 20. 63%, respectively. In the all followed-up patients, 17 cases were detected of local recurrence, the recurrence rate was 26. 98%, and the recurrence rate in the patients with PCNA positive was 71. 43%, while in the patients with COX-2 positive was 73. 68% (P<0. 05). The combined detection of PCNA and COX-2 positive recurrence rate was significantly higher than that of single positive (P<0. 05). Conclusion PCNA and COX-2 in the early laryngeal cancer with negative surgical margins are important biological markers for the evaluation of prognosis of laryngeal cancer patients, and to formulate the subse-quent treatment regimen. The combined detection of two proteins is more reliable for postoperative management.
