How to treat sarcomatoid carcinoma Sarcomatoid Mesothelioma Sarcomatoid RCC is no longer considered as a true subtype since sarcomatoid change represents undifferentiated cells associated with progression of disease in all RCC cell types . Abstract. Sarcomatoid carcinoma, sometimes referred to as pleomorphic carcinoma, is a relatively uncommon form of cancer whose malignant cells have histological, cytological, or molecular properties of both epithelial tumors ("carcinoma") and mesenchymal tumors ("sarcoma"). Sarcomatoid carcinoma (SaC) is a rare variant of squamous cell carcinoma with sarcomatoid features having biphasic characteristic malignant mesenchymal spindle cell and squamous cell component comprising of dysplasia, carcinoma in situ, or invasive carcinoma.

Sarcomatoid carcinoma displays properties of both epithelial and mesenchymal carcinomas. Treating the spindle cell variant is more challenging than other types of mesothelioma because the tumor cells are resistant to therapy and quickly spread or metastasize to new areas. Sarcomatoid carcinomas of the lung are very uncommon tumors, comprising between 0.3 and 3% of all non-small lung carcinomas. Sarcomatoid tumors exhibit lower prevalence of PBRM1 mutations and angiogenesis markers, frequent CDKN2A/B alterations, and increased PD-L1 expression.

Sarcomatoid mesothelioma is the least common cell type of mesothelioma (10-15%) and known for its abnormal spindle shape. a rare variant of squamous cell carcinoma (SCC), has been shown to be biphasic (2) and usually consists of both a conventional epithelial squamous cell component and a sarcomatous spindle cell component. It is characterized by sarcomatous elements with evidence of epithelial differentiation. Sarcomatoid carcinoma represents an aggressive histotype of malignancies that occur at many anatomic sites such as upper respiratory and digestive tracts, kidney, and lung. Synonyms for sarcomatoid carcinoma in Free Thesaurus. Sarcomatoid differentiation in RCC indicates an aggressive subtype of renal parenchymal tumors, and is associated with a poor prognosis.
