Tumour progression and metastasis
The two biological mechanisms that determine types of malignancy are infiltration and metastasis, for which tumour microenvironment plays a key role in developing and establishing the morphology, growth and invasiveness of a malignancy. The microenvironment is formed by complex tissue containing the extracellular matrix, tumour and non-tumour cells, a signalling network of cytokines, chemokines...
متن کاملTumour-To-Tumour Metastasis
With the exception of metastatic involvement of adenomas of endocrine glands, metastasis of one primary tumour to another independent neoplasm is a rare occurrence. This paper records two such examples.
متن کاملTumor progression and metastasis.
It is now widely accepted that cancer is attributed to the accumulation of genetic alterations in cells. Thus, to understand the molecular mechanisms of cancer metastasis, it is indispensable to identify the genes whose alterations accumulate during cancer progression as well as the genes whose expression is responsible for the acquisition of metastatic potential in cancer cells. Molecular anal...
متن کاملTumour to Tumour Metastasis of Malignant Melanoma to Intracranial Tumour
UNLABELLED Tumours can metastasize to sites of other tumours but this is a rare event. The phenomenon has been well described in primary tumours of the lung and breast. This has been described in melanomas but as very rare occurrence. We describe a case of a malignant melanoma that metastasized to a pre-existing meningioma. We have tried to highlight this phenomenon in patient with melanoma and...
متن کاملMechanosignalling in tumour progression
Distinct characteristics of cancer cells govern tumour initiation and progression. The fact that a tumour represents a new entity that is pathologically interposed between normally differentiated tissues generates aberrant mechanical interactions that affect each of the wellknown hallmarks, but also tends to form an additional feature of their own during tumour progression [1]. Genetic mutation...
