摘 要: | Objective To evaluate the prognostic value of lateral pelvic lymph node metastasis on low rectal cancer. Methods One hundred and seventy-six patients with low rectal cancer who underwent radical resection combined with lateral pelvic lymph node dissection between 1994 and 2005 were reviewed. The data of the cases was investigated to define the prognostic value of lateral pelvic lymph node metastasis on the patients. Results Lateral node metastasis occurred in 33 patients (18.8%), and 51.5% of the metastasis occurred in internal iliac nodes or nodes at middle rectal roots and 39.4% in obturator nodes. Age ≤40 years, infiltrative cancer, T3-4 tumor, upward lymph node metastasis were risk factors for lateral node metastasis in low rectal cancer (P < 0.05). The overall 5-year survival rate was 64.1%, and it was 94.1%, 79.1%, 42.1% for patients with TNM stage Ⅰ , Ⅱ , Ⅲ cancer, respectively. Tumor size, depth of infiltration, upward lymph node metastasis, lateral node metastasis was correlated significantly with prognosis (P < 0.05). The 5-year survival rate of the patients without lateral metastasis was 73.6%, which was significant higher than that of patients with lateral metastasis (21.4%, P <0.05). Conclusion Lateralpelvic lymph node metastasis is an important prognostic factor for low rectal cancer.
