Critical assessment of resource waste in staging and follow-up of breast cancer.

BACKGROUND: Breast cancer is a public health problem with both high incidence and cure rates. After treatment, patients are monitored for long periods of time due to the risk of recurrence. Thus, staging and follow-up strategies should consider not only the best results for the patient but also its costs for the public health system. OBJECTIVE: The objective of this study was to quantify the waste of resources on breast cancer follow-up and evaluate its impact on the public health system. METHODS: This is a retrospective analysis of consecutive medical records to identify the intervals between consultations and tests used for staging and during the first 2 years of follow-up of patients with breast cancer treated at a public hospital in Brazil. Data were compared with the guidelines of the main international consensus. RESULTS: Medical records of 60 consecutive patients treated in 2018 were selected, of whom 52 had 2 or more years of follow-up, and 8 had only 1 year of complete follow-up. A total of 34 patients (56.67%) underwent excessive examinations for stating. During follow-up, 125 surplus consultations were performed (33.6%). In this phase, 111 surplus exams were also performed, representing an increase of 100.9%. A total of 423 laboratory tests were performed for 18 patients in the first year and 229 tests for 14 patients in the second year. CONCLUSION: Excessive tests and consultations significantly burdened the Unified Health System without any benefit to patients. Better adherence to staging and follow-up recommendations could reduce costs and optimize the limited resources used in the public health system.

Malignant pericardial effusion as a primary manifestation of metastatic colon cancer: a case report.

BACKGROUND: Pericardial neoplastic involvement is rarely related to primary tumors of the pericardium and is most often caused by spread from other primary sites, such as lung and breast carcinomas, hematological malignancies (lymphoma and leukemia), and melanoma. Although pericardial metastasis from infradiaphragmatic tumors (such as colon cancers) are rare and poorly described in literature, any neoplasm has the potential to metastasize to the pericardium and heart by either contiguity, lymphatic, or hematological spread. CASE PRESENTATION: A 44-year-old previously healthy male Causasian patient had a sudden onset of dyspnea and wheezing. During investigation with echocardiogram, computed tomography and repeated pericardiocentesis, the cause of malignant pericardial effusion was confirmed as primary manifestation of metastatic colon cancer. The patient was treated with appropriate chemotherapy and presented satisfactory disease control. CONCLUSIONS: This report emphasizes the importance of considering the diagnostic hypothesis of occult neoplasia in a patient with pericardial effusion.

Depression, anxiety and spirituality in oncology patients.

OBJECTIVE To relate anxiety and depression levels to the spirituality levels of oncology patients in the ABC region. METHODS Cross-sectional study performed at the ABC University Center oncology outpatient clinics. For the evaluation of spirituality, the Religiosity, Spirituality, and Personal Beliefs instrument of the World Health Organization (SRPB-WHO) was applied. To evaluate the levels of depression and anxiety, the Hospital Anxiety and Depression Scale (HADS) was applied. Qualitative variables were described by frequency and percentage, and quantitative variables by mean and standard deviation or median and range. Relationships were established using either the T-test or Wilcoxon-Mann-Whitney test and correlations with Pearson or Spearman tests, depending on the normality assessed by the Shapiro-Wilk test. RESULTS We included 99 patients, 68% female, with a median age of 60 years (19 to 81). A total of 24% had high or borderline levels of anxiety and 21% of depression. There was a negative correlation between levels of depression and spirituality (rho = -0.44, p <0.001), and anxiety and spirituality (rho=-0.232, p=0.02). We found no significant difference between levels of anxiety, depression, or spirituality when stratified by schooling, income, ethnicity, or marital status. There was a positive correlation between levels of anxiety and depression (cor = 0.477, p <0.001). CONCLUSION Spirituality can be a complementary tool in the treatment of patients with cancer.

Epidemiological profile of Brazilian oncological patients seen by a reference oncology center of the public health system and who migrate in search of adequate health care

SUMMARY INTRODUCTION Structural disparities between different Brazilian regions in public health system cause patients to migrate in search of better conditions to treat their diseases. Besides patient's discomfort, there is a concentration of care in large centres, causing overload to current capacity. OBJECTIVE To evaluate migratory flow and associated factors in a reference service in oncology. METHODS Cross-sectional study conducted at a referral oncology service in Great ABC region of São Paulo. Patients were interviewed, and clinical and demographic data collected. RESULTS Between March-July 2016, 217 patients were included. Analysis showed a divergence between the postal code registered in the medical record and that recorded during the interview in approximately 10% of cases. Of these, 42.9% were residents of other states. Search for treatment motivated most patients to seek service outside their city. CONCLUSION Results reflect the informal search for medical care outside the home area. Besides the direct impact on patients' quality of life, migratory flow has an economic-social impact because these patients place a burden and impose costs on services of cities where they do not perform their responsibilities as citizens. Confirmation of the existence of a significant migratory flow demonstrates the need to discuss restructuring public health policies.

RESUMO INTRODUÇÃO As disparidades estruturais entre diferentes regiões brasileiras no sistema de saúde pública fazem com que os pacientes migrem em busca de melhores condições para tratar suas doenças. Além do desconforto do paciente, há uma concentração de cuidados em grandes centros, causando sobrecarga da capacidade atual. OBJETIVO Avaliar o fluxo migratório e fatores associados em um serviço de referência em oncologia. MÉTODOS Estudo transversal realizado em um serviço de oncologia de referência na região do Grande ABC, em São Paulo. Os pacientes foram entrevistados e dados clínicos e demográficos coletados. RESULTADOS Entre março e julho de 2016 foram incluídos 217 pacientes. A análise mostrou uma divergência entre o código de endereçamento postal registrado no prontuário médico e o registrado durante a entrevista em aproximadamente 10% dos casos. Desses, 42,9% eram residentes de outros estados. A busca de tratamento motivou a maioria dos pacientes a buscar serviços fora de sua cidade. CONCLUSÃO Os resultados refletem a busca informal de cuidados médicos fora da área de residência. Além do impacto direto na qualidade de vida dos pacientes, o fluxo migratório tem um impacto econômico-social porque esses pacientes colocam um fardo e impõem custos aos serviços das cidades onde não executam suas responsabilidades como cidadãos. A confirmação da existência de um fluxo migratório significativo demonstra a necessidade de discutir a reestruturação das políticas de saúde pública.

Time trend and regional variability of mortality rate due to ovarian cancer in Brazil: a 15-year analysis.

Introduction: Ovarian cancer (OC) is the most lethal gynecological tumor. In Brazil, there are important regional differences regarding mortality rates for the same cancer type. Objectives: To analyze the progression of OC mortality rates in Brazil and its regions, in age groups over 50 years, between 2000 and 2015. Methods: Ecological longitudinal study carried out using secondary data from DATASUS (Brazil's public health system database) regarding deaths due to OC in women living in Brazil between 2000 and 2015. We calculated gross and adjusted mortality, estimated the impact of death of OC and proportional mortality rate of all cancer types in women between the age of 50 and 79 years. Results: There were 34.335 deaths due to OC in women in the referred age interval, with a 9% increase in mortality adjusted for age, a 0.05% (P = 0.012) trend and a 24.67% increase in the proportional mortality due to all causes with a 0.02% (P < 0.001) trend. There were statistically significant increases in mortality rates due to OC in the age groups of 50-54 (28,4%, P < 0,05) and 75-79 years (25,1%, P < 0,05). Conclusion: Although there are oscillations in mortality rates of OC in Brazil and its regions over the period studied, this parameter has remained relatively stable.

Purified Dry Paullinia cupana (PC-18) Extract for Chemotherapy-Induced Fatigue: Results of Two Double-Blind Randomized Clinical Trials.

Fatigue is frequent among oncologic patients. Unpurified Paullinia cupana dry extract showed encouraging results for chemotherapy-induced fatigue in our previous studies. We report two randomized, double-blind studies with a standardized dry purified Paullinia cupana extract named PC-18. For both studies, we recruited early breast cancer patients who had an increase in their fatigue scores after their first cycle of adjuvant chemotherapy. In the first study, we compared an oral dose of 37.5 mg of PC-18 twice daily with placebo. In the second study, we examined PC-18 at either 7.5 or 12.5 mg orally twice daily versus placebo. In both studies, PC-18 was not superior to placebo as assessed by both Chalder and Brief Fatigue Inventory (BFI) fatigue questionnaires, probably reflecting unexpectedly good placebo antifatigue activity. Since all capsules employed in both studies contained about 100 mg of magnesium silicate as an excipient, we retrospectively evaluated frozen serum samples from the second study and found a significant increase in magnesium levels after patients received placebo. By multivariate analysis, higher prerandomization magnesium levels and higher BFI scores together with the use of a 12.5 mg dose of PC-18 all correlated significantly with higher posttreatment BFI scores. We observed no significant toxicities in any of the trials. We conclude that the absence of differences between PC-18 and placebo may be due to the unexpectedly high antifatigue activity of the placebo in these studies. Further studies evaluating the role of magnesium supplementation for chemotherapy-induced fatigue are needed.

Linfoma anaplásico diagnosticado de forma incidental após trauma / Anaplastic lymphoma diagnosed out of a incidental form after trauma

O linfoma não Hodgkin de células T periféricas possui um subtipo denominado linfoma anaplásico de células grandes (LACG) que pode apresentar-se sob duas formas variantes que distinguem entre si na apresentação clínica e prognóstico. O artigo a seguir relata o caso de um paciente que teve o diagnóstico desta neoplasia após trauma no pé sofrido por acidente de moto. Relatos de casos publicados previamente na literatura descrevem a associação do surgimento desta entidade em partes do corpo que sofreram traumas locais de origens diversas, sugerindo uma relação direta entre eles através no influxo de células T na carcinogênese desta neoplasia linfoproliferativa.

Carcinoma tímico metastático com resposta prolongada a pemetrexed e octreotide / Metastatic thymic carcinoma with prolonged response to pemetrexed and octreotide

Em adultos os carcinomas tímicos representam cerca de 20% das neoplasias mediastinais. A maioria dos pacientes tem entre 40 e 60 anos de idade e há ligeira predominância do sexo masculino. Em função da raridade da doença não há ensaios clínicos randomizados realizados para orientar a escolha do tratamento na doença metastática refratária ou recorrente. Alguns regimes de segunda linha têm sido usados, a maioria baseada em cisplatina. Como linhas alternativas as opções são pemetrexed, 5-flourouracil associado a leucovorin, gemcitabina, capecitabina e paclitaxel, todas com taxas de resposta pequenas. Relatamos neste artigo um caso de carcinoma tímico tratado com pemetrexed e octreotide com resposta prolongada ao tratamento.
