This study included 60 Egyptian female patients with breast cancer, all of them were subjected to modified radical mastectomy operation. Methods: This study included female patients > 18 years old who have breast cancer with healthy looking non invaded skin of nipple and areola and excluded patients < 18 years old, patients unfit for surger, patients previously subjected to chemo or radiotherapy for breast cancer. We peformed clinical examination of 60 patients with breast cancer. We studied the relevant factors that affect NAC invasion such as patient’s age, menstrual state, family history, tumor size, tumor location (central vs peripheral), tumor to nipple distance, lymphovascular invasion of NAC, lymph node metastasis, histological tumor type, tumor stage, multifocal/multicentric tumors and (ER, PR, HER2) status. Result: In our study, we have shown that NAC invasion is strongly associated with: 1) Nipple retraction as a patient’s complaint;2) Tumor site;3) Tumor-nipple-distance ≤ 4 cm;4) Multifocal/multicentric tumor;5) Tumor grade (grade III tumors);6) Positive lymph node invasion;7) ER and PR receptors negativity;8) HER2 positivity. This helps in preoperative planning for selecting patients for NAS mastectomy. Conclusion: The ideal patients for NAS mastectomy are with these criteria: 1) Clinically normal nipple areola complex;2) Distance from the tumor to the nipple is >4 cm;3) No multifocal/multicentric tumor;4) Absence of lymph node invasion;5) Tumor grade (grade I, II);6) Peripheral not central tumor;7) No sub-areolar lymphovascular invasion (LVI);8) ER receptor positive;9) PR receptor positive;10) HER2 negative.</span>展开更多
目的探讨Kank1基因在肺癌中的表达差异及其临床病理学意义。方法采用免疫组织化学方法,检测66例肺癌组织和20例正常肺组织中Kank1蛋白的表达,结合患者临床资料分析Kank1与肺癌发生发展的相关性。同时通过RT-PCR检测正常支气管上皮细胞...目的探讨Kank1基因在肺癌中的表达差异及其临床病理学意义。方法采用免疫组织化学方法,检测66例肺癌组织和20例正常肺组织中Kank1蛋白的表达,结合患者临床资料分析Kank1与肺癌发生发展的相关性。同时通过RT-PCR检测正常支气管上皮细胞与肺癌细胞中Kank1 m RNA的表达差异。结果Kank1基因在正常肺组织中的阳性表达率95.0%,其在肺癌组织中的阳性表达率为48.5%。Kank1在肺癌组织中的蛋白阳性表达率显著低于其在正常组织中的表达率(P<0.05);此外,其表达与患者有无淋巴结转移、年龄、性别、肿瘤病理分类及分化程度无关,且在正常支气管上皮细胞与肺癌细胞中Kank1 m RNA表达明显有差异。结论 Kank1在肺癌细胞及组织中表达降低,提示其表达下调与肺癌的发生发展密切相关。展开更多
