Abstract:
We report a case of nasopharyngeal carcinoma with Chest Metastasis in a 38-year-old man. The patient presented with nasal obstruction, epistaxis, a huge neck mass and conductive hearing loss in the right ear. Examination under anaesthesia revealed a mass in the nasopharynx, which was confirmed on histology to be squamous carcinoma. He responded remarkably well to external radiotherapy with disappearance of primary tumor and neck metastasis. One year later he presented with thoraco-lumbar spine pain and cough. The nasopharynx and neck remained free of tumor while radiographs demonstrated multiple metastasis to the lungs and vertebrae.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
