Nutritional Status of Patients with Neoplasms Undergoing Ambulatory Chemotherapy and Associated Factors.

Background/objectives: Cancer, a leading cause of mortality globally and in Brazil, is influenced by environmental and behavioral factors, often linked to nutritional deficiencies such as low body mass index and muscle wasting, exacerbating prognostic outcomes and mortality rates. Timely nutritional interventions during chemotherapy are pivotal, necessitating continuous nutritional assessment for effective patient care management. This study aimed to assess the nutritional status of non-metastatic cancer patients undergoing chemotherapy and identify factors influencing their nutritional status.

Cancer symptom clusters, cardiovascular risk, and quality of life of patients with cancer undergoing chemotherapy: A longitudinal pilot study.

Patients with cancer undergoing chemotherapy may have different cancer symptom clusters (CSC) that negatively impact their quality of life (QoL). These symptoms can sometimes arise from the disease itself or as a result of their cancer treatment. This study aimed to: examine the feasibility of longitudinal testing of CSC pattern and QoL in a sample of adult cancer patients undergoing outpatient chemotherapy; to identify the cardiovascular risk of patients with cancer undergoing outpatient chemotherapy; and to investigate the most prevalent CSC and their impact on the QoL of these patients.

Nutritional status of women with non-metastatic breast cancer receiving outpatient chemotherapy.

Objectives: The aim of this study was to evaluate and compare the nutritional status of women with stage I to III breast cancer in the first and third cycles of outpatient chemotherapy and to identify factors associated with it.

Methods: The prospective longitudinal study was conducted at a Reference Hospital for Cancer Care in Brazil and included women aged ≥18 y diagnosed with stage I to III breast cancer receiving outpatient chemotherapy. Assessments were performed during the 1st and 3rd cycles of chemotherapy, including anthropometric measurements, sociodemographic data, clinical information, and quality of life.

Factors Associated with the Nutritional Status of Women with Non-Metastatic Breast Cancer in a Brazilian High Complexity Oncology Center.

Background: Breast cancer poses a significant public health concern owing to its high prevalence and the risk of mortality associated with delayed diagnosis and treatment. The aim of this study was to assess the nutritional status of women with non-metastatic breast cancer and to identify factors associated with it.

Methods: A cross-sectional observational study was conducted at a High Complexity Oncology Assistance Center in the southeast region of Brazil, with the aim of assessing the nutritional status in women undergoing treatment for stage I, II, or III breast cancer.

Roles of chlorophyllin in cell proliferation and the expression of apoptotic and cell cycle genes in HB4a non-tumor breast cells.

Chlorophyllin (Chl) has attracted interest in the scientific community due to its chemopreventive and antimutagenic properties. However, the molecular mechanisms of action of Chl remain unclear. This study assesses the effects on cell proliferation and the expression of genes involved in apoptosis, and the cell cycle in HB4a cells treated with Chl.
