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.

Incidence and risk factors for the development of cerebral metastasis in cervical cancer patients.

OBJECTIVE: Cerebral metastasis (CM) in cervical cancer (CC) cases, although rare, results in high lethality rates. The present study aimed to assess CM incidence in a Brazilian reference CC center and evaluate the risk factors for CM development. Retrospective observational study of patients diagnosed with CC between 2010 and 2017. METHODS: Cumulative CM incidence and incidence density were evaluated. Characteristics associated to CM development risks were identified using crude (cOR) or adjusted (aOR) odds ratios. RESULTS: A total of 3,397 patients were included in this study. Patient age ranged from 18 to 101 years, with a mean age of 48.8±14.0. After a mean follow-up time of 3.2±2.1 years, 51 CM cases were identified, resulting in a cumulative incidence of 1.5% (95% confidence intervals [CI]=1.12-1.97) and an incidence density at the end of the 6th year of 27.4 per 1,000 women/year. Advanced clinical stage (aOR=3.15; 95% CI=1.16-8.58; p=0.025), the presence of previous lung metastasis (aOR=4.04; 95% CI=1.82-8.94; p=0.001) and the adenocarcinoma (aOR=2.90; 95% CI=1.46-5.76; p=0.002), adenosquamous carcinoma (aOR=7.33; 95% CI=2.87-18.73; p<0.001), undifferentiated carcinoma (aOR=14.37; 95% CI=3.77-54.76; p<0.001) and neuroendocrine carcinoma (aOR=21.31; 95% CI=6.65-68.37, p<0.001) histological types were associated with a higher risk for CM development. CM risk was higher in the first years of follow-up, with no cases observed after the 6th year. CONCLUSION: CC patients in advanced clinical stages, displaying previous lung metastasis and non-squamous histological types are at high risk of developing CM.

Conclusão: Destaca-se a relevância clínica deste estudo ao descobrir que o tipo de tumor primário é um fator preditor independente para sobrevida da SCMM. Ao diagnóstico da SCMM, mais da metade dos pacientes não realizam marcha

Introduction: Metastatic Spinal Cord Compression (MSCC) has great potential of irreversible loss of motor and sensory function, and it is considered an oncological emergency. Objective: Evaluate the prognosis of MSCC and the functionality of patients with solid tumors. Method: Cohort study was conducted in patients with cancer who developed MSCC between January 2017 and December 2018. Clinical and socio-demographic data were extracted from physical and electronic charts. Survival analysis was performed by the Kaplan-Meier method. Results: The study included 90 patients who were diagnosed with MSCC. At the time of MSCC diagnosis, 55.5% of patients were unable to walk. Patients with MSCC after lung cancer had 4.1-fold more odds of death (95% CI: 1.79-9.41; p=0.001), those with genitourinary tumors, 1.9-fold higher risk of death (95% CI: 1.06-3.45; p=0,02), and with other types of tumors, 3.1-fold higher risk of death (95% CI: 1.58-6.24; p=0.001) when compared with patients with MSCC after breast cancer. Conclusion: The clinical relevance of this study relies on the findings that the primary type of tumor is a predictive factor for overall survival of MSCC. More than half of the patients were unable to walk at the MSCC diagnosis

Validation of the Portuguese version of functional assessment of cancer therapy-fatigue (FACT-F) in Brazilian cancer patients.

GOALS OF WORK: The purpose of this study was to validate the Portuguese version of the Functional Assessment of Cancer Therapy-Fatigue (FACT-F) in order to establish its assessment properties, including validity and reliability in a sample of Brazilian cancer patients. MATERIALS AND METHODS: Two hundred seventy patients with different types of cancer were included for this study; the mean age was 50.5 years. The reliability was assessed by internal consistency and reproducibility. Construct validity was assessed through convergent validity and discriminant validity. Convergent validity was examined by comparing the FACT-F to the SF-36. Discriminant validity of the FACT-F evaluated the ability of the scale to differentiate defined groups, discriminating patients according to Eastern Cooperative Oncology Group Performance Status and different stages of disease. MAIN RESULTS: FACT-F had high internal consistency (Cronbach alpha coefficient was 0.78 for physical well-being, 0.68 for social/family well-being, 0.75 for emotional well-being, 0.74 for functional well-being, 0.91 for fatigue, and 0.92 for total FACT-F). The range of test-retest intraclass correlation was from 0.72 to 0.91 (p < 0.0001). The Pearson product correlation revealed good correlations between the total FACT-F and subscales of the SF-36 in most dimensions, ranging from r = 0.51 to r = 0.76, except for SF-36 physical (r = 0.31). The positive correlations between the SF-36 vitality scale and FACT-F total (r = 0.76) and the fatigue subscale (r = 0.77) support the convergent validity. CONCLUSIONS: The Portuguese version of FACT-F is a reliable and valid instrument to assess quality of life and fatigue, representing a valid tool to screen cancer-related fatigue in Brazilian cancer patients.

Reproducibility of functional assessment of Cancer therapy-fatigue (FACT-F) questionnaire for cancer patients

Objective: The objective of this study was evaluating the reproducibility in Portuguese of Functional Assessment of Cancer Therapy-Fatigue (FACT-F) questionnaire for cancer patients by applying it according to the test-retest method. Material and Methods: Subjects were 85 cancer patients with an average age of 51.0 years, being 56 (65.9%) women and 29 (34.1%) men. FACT-F questionnaire consists of 40 items, divided in five domains, and is applied for evaluating quality of life and fatigue in patients with cancer. We used as a measuring tool intraclass correlation coefficient values obtained from two measures of test-retest and scatter plot proposed by Bland-Altman. Results: In 36.5% of cases the questionnaire was self-administered, and in 63.5% of the cases read by an interviewer and filled after verbal answer. Intraclass correlation coefficient values found for the domains were: physical well-being 0.72; social/family well-being 0.91; emotional well-being 0.90; functional well-being 0.86; fatigue subscale 0.88, and for the FACT-F 0.91. The Bland-Altman plot showed to be adequate, since most points were within the limits of reliability. Conclusions: FACT-F questionnaire in Portuguese has good test-retest reproducibility in patients with different types of cancer, performance status and stages.
