Introdução: O câncer é uma das doenças mais prevalentes no mundo. Todos os anos várias pessoas passam pela cirurgia de mastectomia que visa a retirada do tecido mamário para auxiliar no tratamento oncológico. Objetivos: Revisar o estudo da análise da recorrência de câncer oncológico através da análise do tecido mamário individual. Métodos: Este trabalho trata-se de um revisão de literatura na qual foi feita com base no levantamento de dados através de artigos do National Center for Biotechnology Informations.Resultados: Nota se que durante o tratamento de pacientes oncológicos mamários a necessidade em sua maioria da retirada do tecido mamário, buscando estética do paciente faz se á uma mastectomia que retire o mínimo possível. tornando se cada vez mais comum caso em que os pacientes fazem mastectomia em que a pele ou o mamilo são preservados. Contudo deve-se levar em conta outros aspectos além da estética. A prevalência da eficácia e segurança desses procedimentos, especialmente NSM e mastectomia poupadora de aréola, no tratamento do câncer de mama permanecem questionáveis. Uma revisão recente do Cochrane Breast Cancer Group concluiu que a qualidade das evidências para todos os resultados, incluindo sobrevida global e local livre de doença, foi considerada muito baixa.¹ Embora exista um valor de referência oncologicamente seguro (5 mm) para o retalho cutâneo, na prática clínica e nos exames de imagem, observamos resultados variáveis, como retalhos não homogêneos finos em alguns pontos, mas espessos em outros bem como como visível e grandes quantidades de RBT². A falta de padronização desses procedimentos cirúrgicos e análises de imagem tem impacto significativo na decisão quanto à radioterapia adjuvante (RT) após mastectomias menos radicais. A diferença entre os diferentes níveis entre o resíduo de tecido mamário em pacientes que passaram por cirurgia devido a tratamento oncológico.³ Conclusões: Este trabalho permitiu observar a necessidade da retirada total do tecido mamário, para melhor eficácia no tratamento de câncer.

BACKGROUND: Carbohydrate antigens 15-3 (CA 15-3) is a conventional tumor marker in breast cancer, with low sensitivity and specificity. MicroRNA (miRNA)-21 showed its stability in circulation and could serve as powerful biomarker. The aim of this study was to evaluate miRNA-21 as breast cancer biomarker compared to CA 15-3 in Indonesian population.METHODS: Circulating plasma miRNA-21 expression was measured using qRT-PCR in 49 patients at various stages of breast cancer and 16 healthy controls. The relative expression value of miRNA-21 was calculated using 2-ΔΔCt. Meanwhile, CA 15-3 was quantified using electrochemiluminescence immunoassay (ECLIA) methods. The results of miRNA-21 and CA 15-3 plasma circulating expression were compared with controls at each stage and between stages of breast cancer.RESULTS: CA 15-3 median level in breast cancer group was 1.60 times higher compared to control group (p=0.019), 21.00 m/mL and 13.05 m/mL, respectively. Median miRNA-21 expression in breast cancer group was elevated 4.92 folds compared to control group (p=0.001), 4.43 and 0.90, respectively. There was no significant difference of CA 15-3 level between controls and all stages of breast cancer group. CA 15-3 cut-off value was 15.05 m/mL (p=0.016) with 59.2% sensitivity and 62.5% specificity. Meanwhile, there was a significant difference of miRNA-21 expression between controls and most stages of breast cancer group. Circulating miRNA-21 expression cut-off value was 2.07 (p=0.000) with 91.8% sensitivity and 87.5% specificity.CONCLUSION: Circulating miRNA-21 expression and CA 15-3 levels were significantly increased in breast cancer group compared to control group. The miRNA-21 expression increased consistently with breast cancer stage progression. miRNA-21 could serve as superior biomarker compared to CA 15-3.KEYWORDS: biomarker, breast cancer, circulating plasma, liquid biopsy, miRNA-21

Instability Coefficient

In the present work, we analyzed some emotional mechanisms (emotion dysregulation—ED, negative affect—NA, and emotional vulnerability) involved in chronic diseases by means of an interdisciplinary approach. We started from the conceptualization of emotions as a complex dynamic system that can be investigated and understood within a framework inspired by Chaos Theory. An “instability coefficient” Δ was computed to analyze ED mechanisms, NA, and emotional vulnerability in different disease groups (blood cancer, breast cancer, hypertension) as well as in healthy persons. This coefficient, recently defined by our group, computes the Euclidian distance between the pairs of vectors whose components are similar or reverted items of a test measuring ED. The emotional and somatic systems were considered as two complex dynamical systems in interaction. Due to this interaction, and as a result of the laws of complexity, a small perturbation in an inner state of the emotional system could generate an important reaction in the somatic system in time. The emotional vulnerability reflected by high values of Δ was associated with the chronic disease condition. The differences between illness groups and healthy persons, as well as between the three disease groups in Δ values, were analyzed. The results showed that there were significant differences between the chronic disease groups in Δ values. The most highly significant differences in Δ values were reported between the breast cancer group and the healthy group on one hand and between the breast cancer group and the blood cancer group on the other hand. The less significant differences in Δ values were noticed between the hypertension group and the control group. Δ was significant in predicting ED and NA. Compared to the classical approaches, the original contribution of our research is that these results encourage us to propose this interdisciplinary method of assessment as a challenging, valid tool of investigation and understanding of complex phenomena that occur in the emotional and somatic system.

The levels of CA 549 and SP2 were measured in 430 subjects: 100 healthy blood donors, 130 patients with benign diseases and 200 postoperative breast cancer patients. In the latter group, the serum levels of CA 15.3, CEA and TPA were also measured. The Kolmogorov-Smirnov, Mann Whitney and McNemar tests were used for statistical analysis. The upper normal limits were established on the basis of the values obtained in the healthy blood donors group, the benign diseases group and R.O.C. analysis of the breast cancer group. They were: CA 549 = 13 U/ml, SP2 = 14 U/ml, CA 15.3 = 35 U/ml, CEA = 5 ng/ml and TPA = 110 U/ml. The sensitivity, specificity and accuracy in the breast cancer group were, respectively: CA 549 = 78.1%, 97.1% and 88%; SP2 = 21.9%, 90.4% and 57.5%; CEA = 66.7%, 95.2% and 81.5%; CA 15.3 = 80.2%, 98.1% and 89.5%, and TPA = 73.9%, 78.8% and 76.5%. Statistical analysis showed significant differences only between CA 15.3, the marker which gave the best results, and SP2 (p<0.001). There were no significant differences with the association of two or three tumor markers.
