Abstract

To assess aspects related to cancer in indigenous population. This is a retrospective study developed in a public university hospital. We included patients with 18 or more years of age, diagnosed with solid tumors, and followed between 2005 and 2015. Clinical features were assessed by descriptive statistics, and survival was evaluated by Kaplan-Meier curves and multivariate Cox regression. Fifty patients were included. The cancer incidence was 15.73 per 100,000. The mean age at diagnosis was 54 years and most patients were female (58%). Cancer of the cervix (28%) and prostate (16%) were the most common. The mean time between the onset of symptoms and the diagnosis was 9 months and from diagnosis to the treatment was 3.4 months. Disease diagnosed at stage IV (17%) had worse overall survival (HR: 11.4; p<0.05). The 5-year survival rate ranged from 88% for prostate cancer to 0% for lung cancer. All 5-year survival rates were lower as compared to other populations. The most prevalent cancer sites were cervix and prostate. Disease stage and primary site were prognostic factors. Avaliar os aspectos relacionados a câncer em populações indígenas. Estudo retrospectivo conduzido em um hospital universitário público. Foram incluídos pacientes com 18 anos ou mais, diagnosticados com tumores sólidos e acompanhados entre 2005 e 2015. Os aspectos clínicos foram avaliados por meio de estatística descritiva, e a sobrevida foi avaliada por meio de curvas de Kaplan-Meier e regressão multivariada de Cox. Foram incluídos 50 pacientes. A incidência de câncer foi 15,73 por 100 mil. A média de idade ao diagnóstico foi 54 anos, e a maioria era do sexo feminino (58%). O câncer de colo uterino (28%) e o de próstata (16%) foram os mais frequentes. O tempo médio entre o início dos sintomas e o diagnóstico foi 9 meses, e entre o diagnóstico e o tratamento, de 3,4 meses. Doença diagnosticada no estágio IV (17%) resultou em pior sobrevida global (HR: 11,4; p<0,05). A sobrevida em 5 anos variou de 88% para o câncer de próstata a 0% para pulmão. Todas as taxas de sobrevida em 5 anos foram menores em comparação a outras populações. Os locais mais frequentes de neoplasia foram colo de útero e próstata. O estágio da doença e o sítio primário foram fatores prognósticos.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 October 2016.
All research outputs
#22,759,452
of 25,374,647 outputs
Outputs from Einstein (São Paulo)
#503
of 576 outputs
Outputs of similar age
#341,814
of 399,679 outputs
Outputs of similar age from Einstein (São Paulo)
#29
of 33 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 576 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 399,679 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
