Ocorrência de neutropenia em mulheres com câncer de mama durante tratamento quimioterápico

In vitro results with minimal blood toxicity of a combretastatin A4 analogue

Cancer is a disease caused by uncontrolled cell growth that is responsible for several deaths worldwide. Breast cancer is the most common type of cancer among women and is the leading cause of death. Chemotherapy is the most commonly used treatment for cancer; however, it often causes various side effects in patients. In this study, we evaluate the antineoplastic activity of a parent compound based on a combretastatin A4 analogue. We test the compound at 0.01 mg mL- 1, 0.1 mg mL- 1, 1.0 mg mL- 1, 10.0 mg mL- 1, 100.0 mg mL- 1, and 1,000.0 mg mL- 1. To assess molecular antineoplastic activity, we conduct in vitro tests to determine the viability of Ehrlich cells and the blood mononuclear fraction. We also analyze the cytotoxic behavior of the compound in the blood and blood smear. The results show that the molecule has a promising antineoplastic effect and crucial anticarcinogenic action. The toxicity of blood cells does not show statistically significant changes.

Neutropenia: occurrence and management in women with breast cancer receiving chemotherapy

OBJECTIVES

to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer.

METHODS

observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant.

RESULTS

79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia.

CONCLUSION

neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care.

Adverse reactions to docetaxel: an active survey

The rates of breast cancer mortality remain high in Brazil. Docetaxel is a semi-synthetic taxane used to treat various tumors, particularly tumors of the breast, lung and prostate. In this study ADR that occurred in 45 docetaxel users with breast cancer were surveyed. They were identified by type, causality (Naranjo algorithm and World Health Organization categories) and, if considered probable or defined, rated for severity according to SOBRAFO proposal (2007). A total of 325 ADR were observed: 165 in the first, 137 in the second and 23 in the third cycle. Fifty seven ADR were immediate and the others, late. Fatigue and exhaustion for more than five days, classified as Grade 3 by SOBRAFO (2007), were reported as the primary late RAM. There was no significant difference in the occurrence of immediate and late ADR between cycles (p=1 and p=0.3577, respectively). The presence of a pharmacist gave the patients a better understanding of the occurrence of RAM, especially those that occur outside the hospital, between chemotherapy cycles and are often not reported to the healthcare team, creating institutional demands and reaching the goal to track, observe and correlate the RAM for each user.
