ABSTRACTand extrapelvic lymph nodes (1,8). Despite the fact that metastatic brain tumors are said to constitute up to 50% of adult brain tumors, those arising from cervical cancer are a rare event, with an incidence rate between 0.4 to 1.2% among cervical cancer cases (3,4,7,13). Therefore, there are only case reports or small case series related to these rare metastases in the english medical literature (10)(11)(12)(15)(16)(17). The median survival time from determination of brain metastasis from █ INTRODUCTION U terine cervical cancer is the second most common malignancy in women worldwide (9,14,16). It spreads most often via local extension and through the lymphatics to the retroperitoneal lymph nodes. Distant organs are reached by hematogenous dissemination, which occurs infrequently, but especially influences the lungs, liver, bones, AIm: To investigate the clinical features, prognostic factors and survival times of cervical cancer patients with brain metastasis.
mATERIAl and mEThODS:We retrospectively reviewed the medical records of 820 patients with cervical cancer. Data were analyzed using SPSS version 12.0 statistical software (SPSS, Chicago, IL, uSA). Overall survival, time interval from diagnosis of cervical cancer to identification of brain metastasis, and median survival time after diagnosis of brain metastasis were calculated using Kaplan-Meier curve analysis. The log-rank test was used to compare differences in survival. Differences were assumed statistically significant when p-values were <0.05.
RESUlTS:The incidence of brain metastases from cervical cancer in our institution was 1.82% (15/820) over a ten-year period. The median time interval from diagnosis of cervical cancer to detection of brain metastasis was 12.5 months (range: 2.9-91.9 months). Stage and tumor diameter were found to be significant relating to the interval from diagnosis of cervical cancer to detection of brain metastasis (p=0.001 for both).
CONClUSION:This study provides much information about the prognosis of patients with brain metastases from cervical cancer and highlights the importance of initial stage and tumor diameter when determining the time interval until development of brain metastasis.
