[Clinicopathologic characteristics and risk factors for lung metastasis after radical hysterectomy in early-stage cervical cancer].

OBJECTIVE

To discuss the clinicopathologic characteristics and risk factors for lung metastasis of early-stage cervical cancer after radical hysterectomy.

METHODS

The complete clinicopathologic data of patients with lung metastasis of cervical cancer after radical surgery from January 2008 to December 2013 admitted in Zhejiang Cancer Hospital were retrospectively analyzed by univariate and multivariate analysis.

RESULTS

(1) There were 38 cases of early cervical cancer suffered from lung metastasis after radical hysterectomy during the period. The median age at diagnosis of cervical cancer was 46 years, the average lung metastasis time was 13 months after operation, 50.0% (19/38) cases occurred in the first year. Thirty-one cases were squamous cell carcinoma and 7 cases were non-squamous cell carcinoma. (2) Univariate analysis showed that age, clinical stage, manner of tumor growth, tumor grade, perineuronal invasion, para-aortic lymph node metastasis were not significant effect on postoperative lung metastasis (all P>0.05). But tumor size, histologic types, depth of stromal invasion, uterine body infiltration, lympho-vascular space invasion,pelvic lymph node metastasis, positive margin and abnormal tumor markers were significantly correlated with postoperative lung metastasis (all P<0.05). Multivariate analysis showed that only tumor size, histologic types and pelvic lymph node metastasis were independent risk factors for lung metastasis of cervical cancer (P<0.05).

CONCLUSIONS

Patients of early-stage cervical cancer with lung metastasis mostly occurs within 1 year after radical hysterectomy. Local large tumor lesions (tumor size >4 cm), non-squamous cell carcinoma and pelvic lymph node metastasis were more likely to have lung metastasis.
