Incidence and risk factors associated with the development of metastatic spinal cord compression due to bone metastasis in women with cervical cancer.

PURPOSE: The aim of this study was to determine the incidence and factors associated with the development of metastatic spinal cord compression (MSCC) after cervical cancer (CC). METHODS: This retrospective cohort of 3551 women with CC who underwent treatment at the Brazilian National Cancer Institute were included in the study. Clinical and sociodemographic variables were obtained from the Hospital Cancer Registry and from hospital records. A descriptive study of the population was carried out, using means and standard deviations or frequencies and percentages. The Kaplan-Meier curve was used to identify annual incidence rates. Associations between the independent variables and the outcome (MSCC) were evaluated by a univariate analysis, applying crude and adjusted odds ratios (aOR) assuming 95% confidence intervals. RESULTS: The MSCC incidence was of 1.5% (n = 51), associated to advanced staging (aOR = 2.65, 95% CI: 1.45-4.85, p = 0.001) and initial treatment with concomitant chemotherapy and radiotherapy (aOR = 4.40, 95% CI: 1.74-11.13, p = 0.002). CONCLUSIONS: Our findings revealed the incidence and factors associated with MSCC, indicating a subset of patients who may be potential targets for the prevention and early treatment of this condition, indicating unprecedented and relevant data for the Brazilian epidemiological scenario due to the high CC incidence rates.

Prognostic factors for brain metastasis in women presenting cervical cancer.

PURPOSE: Although rare, brain metastases (BM) from cervical cancer (CC) are highly lethal. Adequate patient selection for specific treatments can improve survival rates in patients afflicted by this condition. This study aimed to describe the characteristics of CC patients who developed BM and overall survival-associated factors. Brain metastasis impact on the overall survival was assessed as a secondary objective. METHODS: This assessment comprises a retrospective cohort study on 3394 women presenting CC diagnosed between January 2010 and December 2017 at a single referral center. Incident BM cases were included. Descriptive statistics were calculated. Kaplan-Meier curves were used for the survival analysis and a Cox proportional hazards regression model was applied to explore the risk of death according to the analyzed independent variables. RESULTS: A total of 48 incident BM cases were identified. The median time between CC diagnosis and BM development was 1.5 years. Headaches (29.2%), dizziness/altered balance (29.2%), vertigo (29.2%) and motor disturbances (25.0%) were the most common signs and symptoms at presentation. Median overall survival after BM diagnosis was of 1.6 months (95% CI 0.9-2.3) while in the group of women without BM it was 5.5 years (95% CI 4.9-6.1). Concerning the Cox multivariate analysis, presenting one extracerebral metastases site (HR 2.8; 95% CI 1.3-6.2; p = 0.009) and receiving supportive treatment (HR 13.7; 95% CI 3.1-60.5; p 0.001) were independently associated with the risk of death. CONCLUSION: The median survival of women with BM following CC was poor. Women without extracerebral metastases and undergoing multimodal treatment displayed better overall survival rates.
