Аннотация
BACKGROUND: The incidence of lymph node metastasis in pT1 epithelial ovarian cancer is between 5% and 21%. Most cases with lymph node metastasis are those of serous carcinoma; it is relatively rare in mucinous carcinoma. Therefore, there is a recent trend to omit systematic lymphadenectomy in early stage mucinous carcinoma. The purpose of this study was to verify whether the omission of systematic lymphadenectomy in mucinous carcinoma is oncologically safe.
METHODS: We reviewed all pT1 epithelial ovarian cancer cases that were treated in our hospital between January 2002 and December 2015.
RESULTS: Fiftynine cases of pT1 epithelial ovarian cancer were included. The overall rate of lymph node metastasis was 6.8%(4 in 59). It was 6.5%(2 in 31)in clear cell carcinoma and 22.2%(2 in 9)in mucinous carcinoma.
CONCLUSION: According to our study, lymph node metastasis in pT1 mucinous carcinoma has a rate of 22.2% and some affected cases were not detected by presurgery imaging studies. Therefore, we need to be careful about the omission of systematic lymphadenectomy in mucinous carcinoma.
