小细胞和非小细胞肺癌之间的差异

这key difference在小细胞和非小细胞肺癌之间起源。这small cell lung cancer is a type oflung cancerarising from the neuroendocrine cells whereas the non-small cell lung cancer arises due to varied reasons and has three main varieties based on the origin; the鳞状细胞癌，腺癌and large cell carcinoma. Carcinomas is the medical term for serious invasive cancer of epithelial origin.

Lung cancers are one of the commonest malignancies with a high rate of incidence and account for millions of deaths annually all around the globe. Smoking is identified as the main risk factor for lung cancers, but it is not the sole contributory factor. These cancers can be divided into two broad categories as small cell cancers and non-small cell cancers. Small cell cancers arise from neuroendocrine cells and are therefore associate with different paraneoplastic syndromes. The non small cell cancers have three main subtypes; the squamous cell cancers, adenocarcinomas, and large cell cancers. Squamous cell cancers and adenocarcinomas originate from theepithelial cellsand glandular tissues respectively, but the origin of large cell cancers cannot be ascertained because they are poorly differentiated.

什么是小细胞肺癌?

小细胞癌是由神经内分泌细胞引起的一种肺癌。这y usually occur in the central regions of the lungs and are associated with early metastasis.

由于它们来自神经内分泌细胞，因此它们分泌不同的激素。

什么是非小细胞肺癌？

这re are three main varieties of non-small cell carcinomas such as squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.

Squamous Cell Cancers

Squamous cell cancers arise from the epithelial cells and are associated with keratin production. The tumor can cavitate and often causes airway obstruction along with post obstructive infections.

腺癌

腺癌arise from the mucus-secreting glandular cells. These are the commonest type of lung cancers among nonsmokers. They usually develop in the peripheral zones of the lungs.

Large Cell Carcinoma

Large cell carcinomas are often poorly differentiated and metastasize in their early stage.

What are the Similarities Between Small Cell and Non Small Cell Lung Cancer?

Etiological Factors– all the types of lung cancers share common etiological factors which include the followings,

• 抽烟
• Exposure to radiatio
• Asbestos
• 芳烃
• Exposure to chemicals such as arsenic

宿主因素– such as immunodeficiency and chronic lung diseases have also been identified as risk factors for both lung cancers.

临床表现- 尽管肺癌的种类不同，但它们都有相似的临床情况，

• 由于局部咳嗽，呼吸困难，胃痛，胸痛，声音的嘶哑，胸部反复感染，胸腔积液引起的症状
• 症状是由于转移性传播瘙痒，黄疸，出血表现，棘手的背痛，最近发作癫痫发作，清晨头痛而引起的。

Investigations- 以下一组调查是为了诊断肺癌的诊断，

• Chest x-ray
• CT
• MRI
• 宠物
• Bronchoscopy
• 支气管协会USS

Management of lung cancers –在肺癌的早期阶段，手术仍然是最有效的治疗疗法。放射疗法也已被证明可有效治愈早期肺癌。考虑到晚期恶性肿瘤或患者不适合接受手术时，考虑了姑息治疗。

What is the Difference Between Small Cell and Non Small Cell Lung Cancer?

小细胞癌是由神经内分泌细胞引起的一种肺癌。另一方面，根据其起源，有三种非小细胞癌的主要品种。即，鳞状细胞癌，腺癌和大细胞癌。它们是由于各种原因而出现的。这是小细胞和非小细胞肺癌之间的关键区别。

此外，小细胞和非小细胞肺癌之间的另一个区别是，小细胞癌通常与副肿瘤表现相关。但是，相反，非小细胞癌具有副塑性表现很少。

概括– Small Cell vs Non Small Cell Lung Cancer

这re are two main groups of lung cancers as small cell carcinomas and large cell carcinomas. There are three subtypes of non-small cell cancers like squamous cell cancers, adenocarcinomas, and large cell carcinomas. Small cell carcinomas arise from the neuroendocrine cells. Squamous cell carcinomas and adenocarcinomas originate from the epithelial cells and glandular tissues respectively, but the origin of large cell cancers cannot be ascertained because they are poorly differentiated. This is the main difference between these groups of lung cancers.
