title: Relationship between lymph node metastases and histopathological parameters in carcinoma cervix: a multivariate analysis.
abstract: A retrospective review of 360 cases of carcinoma of the cervix with clinical stage IB and IIA who had undergone radical hysterectomy and pelvic node dissection between 2000 and 2005 was carried out. Lymph node metastasis was present in 79/360 patients (21.9%). LVSI positivity, full thickness stromal invasion, involvement of the uterine isthmus, positive parametrium, positive vaginal margins, involvement of uterine corpus was seen in: 25.3% and 9.2% (p < 0.001); 63% and 32% (p < 0.001); 32.9% and 13.8% (p < 0.001);15.2% and 5% (p < 0.004); 24% and 14.2% (p < 0.005); 17.7% and 13.8% (p = 0.11) of the patients, with and without lymph node metastasis, respectively. The tumour size was <4 cm in 50.6% and 58.3% and >4 cm in 49.3% and 41.6% of the patients, with and without lymph node metastasis, respectively (p = 0.22), which was statistically not significant. In the majority of patients, the histopathology type was squamous cell carcinoma in both the groups. In patients with lymph node metastases 79.7% had grade III tumour as compared with 69.5% in patients without lymph node metastases (p = 0.19). Multiple logistic regression indicated that only lymphovascular space involvement and full thickness stromal invasion were statistically significant (p < 0.001 and p < 0.002, respectively) for lymph node metastasis.
