ABSTRACT

Background: Carcinoma of the breast is a leading cause of death in women and needs to be evaluated at an early stage. FNAC helps in rapid diagnosis of breast lesions and their management. Objective: To study the diagnostic efficacy of FNAC in breast lesions. Materials and methods: Three year retrospective study of 105 cases of breast lump was conducted which included cases, where FNAC and histopathological correlation was available. The cytological diagnosis was classified as inflammatory lesions, benign, atypical probably benign, suspicious for malignancy and malignant. Results: On cytology out of 105 cases, 57 were benign, 7 inflammatory lesions, 34 malignant and 7 were inadequate. Fibroadenoma was the most common benign lesion noted in age group of 21-30 years and infiltrating ductal carcinoma was the most common malignant lesion in 31-40 years age group. Diagnostic accuracy, sensitivity and specificity of this study were 96.93%, 91.89% and 100% respectively. Conclusion: FNAC of breast lesions is a simple, safe and effective modality in pre-operative assessment of benign and malignant lesions and shows high accuracy, sensitivity and specificity.

ABSTRACT

Molecular plant components have long been aimed at the angiogenesis and anti-angiogenesis pathways, and have been tested as sources for antineoplasic drugs with promising success. The present work deals with the anti-angiogenic effects of Methyl Jasmonate. Jasmonate derivatives were demonstrated to selectively damage the mitochondria of cancer cells. In vitro, 1-10 mM Methyl Jasmonate induced the cell death of the human umbilical vein endothelial cells (HUVEC) and the Murine melanoma cells (B16F10), while micromolar concentrations were ineffective. In vivo, comparable concentrations were toxic and reduced the vessel density of the Chorioallantoic Membrane of the Chicken Embryo (CAM). However, 1-10 µM concentrations produced a complex effect. There was increased capillary budding, but the new vessels were leakier and less organised than corresponding controls. It is suggested that not only direct toxicity, but also the drug effects upon angiogenesis are relevant to the antineoplasic effects of Methyl Jasmonate.


Moléculas de origem vegetal são, há muito, conhecidas como substâncias ativas sobre as vias de angiogênese e antiangiogênese e foram testadas como fonte de drogas antineoplásicas com sucesso promissor. Este trabalho trata dos efeitos antiangiogênicos do Metiljasmonato, um protótipo da família dos derivados do ácido jasmônico, que danificam seletivamente a mitocôndria de células neoplásicas. In vitro, metiljasmonato 1-10 mM promoveu a morte celular de células endoteliais humanas de cordão umbilical (HUVEC) e de melanoma murino (B16F10); concentrações micromolares foram inócuas. In vivo, concentrações equivalentes foram tóxicas e reduziram a densidade de vasos em membranas corioalantoicas de embrião de galinha (CAM). Entretanto, concentrações entre 1-10 µM produziram um efeito complexo. Ocorreu aumento no brotamento capilar, mas os novos vasos apresentaram-se frágeis e menos organizados que os controles correspondentes. Sugere-se que, além da toxicidade direta contra as células tumorais, a ação do metiljasmonato sobre a angiogênese seja relevante para seu efeito antineoplásico.
