Introduction: Breast cancer is the most common neoplasm among women in Brazil and worldwide, when non-melanoma skin tumors are excluded. Cancer treatment can trigger a systemic response characterized by inflammation, immunosuppression, and reduced energy metabolism. In addition, there are psychosocial factors that contribute to the onset of adverse events, with asthenia being one of the main ones during breast cancer treatment. Objective: To characterize the presence of asthenia and the nutritional status of women undergoing treatment for breast cancer. Methods: This is a retrospective study of a prospective observational cohort, conducted between January and September 2023, in private oncology clinics in the metropolitan area of Belém (Pará). Women aged 18 years or older and diagnosed with breast cancer at any stage of treatment were included. Data were collected during a nutritional consultation. Nutritional status was assessed by the Scored Patient-Generated Subjective Global Assessment (PG-SGA) and by the Body Mass Index (BMI), according to WHO criteria. The presence of asthenia was identified by self-report. To obtain the results, descriptive statistics were used to obtain measures of central tendency and dispersion, as well as absolute and percentage frequencies. The study is part of the project "Clinical and nutritional assessment of cancer patients treated at a private reference center in Belém-Pará", approved by the Research Ethics Committee (opinion no. 5,763,919). All participants included in the analysis signed the Free and Informed Consent Form. Results: A total of 131 women were included in the analysis. Their mean age was 57.5 ± 14.2 years. Of these women, 55.7% (n = 73) had undergone some form of prior treatment at the time of the consultation. The assessment of nutritional status using the PG-SGA showed that 77.1% (n = 101) of the patients were classified as well-nourished (category A), 19.8% (n = 26) as moderately malnourished (category B), and 3.1% (n = 4) as severely malnourished (category C). Regarding BMI, the median was 26.9 kg/m² (16.2; 43.1), and the majority of the sample (63.4%; n = 83) was overweight. The presence of asthenia was observed in 27.5% (n = 36) of patients, with the highest rates observed in elderly women (58.3%; n = 21), women classified as severely malnourished by the PG-SGA or underweight by the BMI (25%; n = 9), as well as in those who underwent three or more treatment modalities (19.4%; n = 7). Conclusion: The majority of study participants had good nutritional status, however the presence of asthenia was greater in elderly women and those with compromised nutritional status, as well as in women who had already undergone multiple treatments. Therefore, the importance of identifying nutritional and functional risk in women with breast cancer is highlighted, aiming at early nutritional intervention to improve clinical outcomes and their quality of life.
It is with great enthusiasm that we present the Annals of the Oncology International Symposium 2025, an event that continues to solidify its significance in the oncology landscape of northern Brazil. Held in Belém, Pará, Oncology 2025 centered around the theme "The cancer control challenge: better knowing it to best facing it," dedicating itself to exploring the latest frontiers in cancer treatment and prevention.
This year, the symposium provided a deep dive into the essential role of knowledge in the fight against cancer, presenting new perspectives and scientific advancements across various areas of oncology. Renowned global experts gathered to share their most recent research and innovative approaches, offering participants a comprehensive view of the challenges faced by healthcare professionals and patients worldwide.
Presentations and discussions during the event focused on critical topics such as the use of new technologies, advancements in personalized therapies, and more effective prevention strategies. Additionally, particular attention was given to the unique challenges faced by the Amazon region, with efforts aimed at developing region-specific solutions to meet local needs.
Beyond being a high-caliber academic event, Oncology 2025 stood out as a moment for integration and professional networking, with the warm hospitality of the city of Belém offering participants a unique experience. This event became a platform for exchanging ideas, where science, culture, and humanity came together in pursuit of a common goal: to improve cancer control both in Brazil and globally.
This collection of abstracts and articles presented during the event reflects the ongoing dedication to research and the development of innovative solutions, highlighting the importance of collaboration and shared knowledge in the fight against cancer.
