RESUMO

PURPOSE: Breast cancer (BC) is the most common type of cancer among women in Brazil. Evidence shows that delayed treatment onset is associated with increased mortality. This study aimed to evaluate median days between diagnosis and treatment and factors associated with delayed start of treatment (> 60 days after diagnosis): stage, treatment received, subtype, epidemiological characteristics, and type of healthcare coverage. METHODS: This analysis included 1709 stage I-III BC patients from AMAZONA III, a prospective, observational study, diagnosed from January 2016 to March 2018 in 22 centers in Brazil. RESULTS: The median number of days from diagnosis to beginning of first oncologic treatment was 46 days (IQR 28-75) overall, 43 days (IQR 25-75) for stage I disease, 49 days (IQR 28-81) for stage II, and 44 days (IQR 30-68) for stage III, (p = 0.1180). According to first treatment received, diagnosis-to-treatment interval was 43 days (IQR 29-65) for neoadjuvant chemotherapy and 48 days (IQR 26-81) for surgery. Diagnosis-to-treatment interval was higher in women treated in the public system versus the private system (56 vs. 34 days, p < 0.0001). Patients in the public system had an increased odds of delayed treatment initiation (OR 4.74 95% CI 3.09-7.26, p < .0001). The longer interval from diagnosis to treatment in the public system was independent of clinical stage, type of treatment (systemic vs surgery first), subtype and region of the country. CONCLUSION: By characterizing the delays in care delivery, our study will aid stakeholders to better design interventions and allocate resource to improve timely treatment for breast cancer in Brazil.

RESUMO

PURPOSE: In Brazil, the available cancer registries are deficient in number and quality and, hence, little information is known regarding sociodemographic, clinicopathological characteristics, treatment patterns, and outcomes of breast cancer (BC) patients. We performed the AMAZONA III/ GBECAM 0115 study and in this analysis, we describe patients' characteristics at diagnosis and their association with health insurance type. METHODS: This is a prospective cohort study developed in 23 sites in Brazil including women with newly diagnosed invasive BC from January 2016 to March 2018. In order to compare healthcare insurance type, we considered patients who were treated under the Brazilian public health system as publicly insured, and women who had private insurance or paid for their treatment as privately insured. RESULTS: A total of 2950 patients were included in the study. Median age at diagnosis was 53.9 years; 63.1% were publicly insured. The majority of patients (68.6%) had stage II-III breast cancer and ductal carcinoma histology (80.9%). The most common breast cancer subtype was luminal A-like (48.0%) followed by luminal B-HER2 positive-like (17.0%) and triple-negative (15.6%). Luminal A was more frequent in private (53.7% vs. 44.2%, p < .0001) than public, whereas Luminal B HER2-positive (19.2% vs. 14.2%, p = 0.0012) and HER2-positive (8.8% vs. 5.1%, p = 0.0009) were more common in patients with public health system coverage. Only 34% of patients were diagnosed by screening exams. Privately insured patients were more frequently diagnosed with stage I disease when compared to publicly insured patients; publicly insured patients had more stage III (33.5% vs. 14.7%; p-value < 0.0001) disease than privately insured ones. Breast cancer was detected by symptoms more frequently in publicly than in privately insured patients (74.2% vs 25.8%, respectively; p-value < 0.0001). CONCLUSIONS: Patients with public health coverage were diagnosed with symptomatic disease, later stages and more aggressive subtypes when compared to privately insured patients.

RESUMO

The Puerto Rican parrot ( Amazona vittata ) has become an iconic and high-profile conservation species. The cornerstone of the recovery plan for this critically endangered species is an active captive breeding program, management of the wild population, and a long-term reintroduction program. In 2002, 40 adult Puerto Rican parrots that had not produced viable offspring were selected for reproductive assessment at 2 aviary populations in Puerto Rico (Iguaca and Río Abajo), which are the only sources of parrots for release. The goal was to enhance reproductive potential and produce productive pairings in an attempt to augment the population growth and provide ample individuals for reintroduction. Seven Hispanolian Amazon parrots ( Amazona ventralis ) that were used as surrogate parents for the Puerto Rican parrots were also included in the study. This assessment included physical examination, endoscopic evaluation, hematologic and plasma biochemical profiles, viral screening, and hormonal assays. Results of general physical examination and hematologic and plasma biochemical testing revealed overall good health and condition of this subset of the population of Puerto Rican parrots; no major infectious diseases were found. Endoscopic examination also revealed overall good health and condition, especially of females. The apparent low fertility of male birds warrants further investigation. The findings helped to define causes of reproductive failure in the selected pairs and individual birds. New pairings resulting from the assessment helped to augment reproduction of this critically endangered species.

RESUMO

The St Vincent Amazon parrot (Amazona guildingii), listed as a CITES appendix I animal, is endemic only to the mainland of St Vincent and the Grenadines (SVG), Lesser Antilles. A health assessment that included physical examination, hematology, blood parasite evaluation, plasma biochemical analysis, plasma protein electrophoresis, level of exposure to selected infectious agents, and fecal parasites was performed in July 2002 on 37 (51%) of the parrots in the captive population in SVG. Clinical abnormalities noted in the 37 parrots included poor feathers, lipomas, abnormal choanal papillae, obesity, leg ulcers, respiratory abnormalities, cardiac abnormalities, seizure activity, old fractures, missing digits, skin disease associated with mites (Knemidokoptes species), oral granuloma, and a thin, friable beak. Only 7 of the birds were clinically normal on physical examination. Results of hematologic testing, plasma biochemical analysis, and plasma electrophoresis were not statistically different between female and male parrots. No blood parasites were found in any of the 32 samples examined. None of the 36 parrots evaluated had antibodies to the 12 infectious agents tested. Of the 21 fecal samples available, Capillaria species was detected in 1 bird. Findings from this study, in addition to nutritional, genetic, and husbandry evaluations, have been used to make recommendations to the Forestry Department of SVG for improvements in husbandry and veterinary care of this ex situ population.
