Review of Research Paper on Metastasis of Cancerous Tumors

IntroductionEarly diagnosis provides the best desire many have in beating hobocer. Unfortunately, this is non the end of the crowd for many cancer patients. Primary tumours may be successfully handle archean, only to later discover they have metastasized to other areas of the body. The common aesculapian definition of metastasis is The spread of cancer from one part of the body to another. Tumors form from cells that have spread are called secondary neoplasms and contain cells that are equal those in the original ( primary quill) tumor.This definition could be the reason why early treatment of a primary tumor is ineffective against metastatic tumor cells. As the definition suggests, the accepted model for the metastasis of tumor cells is through clonal evolution, where secondary tumors have similar genomes to the primary tumor. Recent studies suggest, however, that this may not be accurate. Significant divergence between primary and second ary tumors in renal cell metastases and tit metastases has been discovered in recent studies. An selection model, one of a parallel evolution, would explain why therapies aimed at primary tumors are unsuccessful against metastatic cells. Further research on this alternative model could lead to therapies that not only target the properties of the primary tumor but also those of the secondary tumor and save many from the onus of fighting cancer again. MethodsThis theme took 386 breast cancer patients and split them into devil groups. M0, patients showing cells with no metastasis, and M1 patients, those that showed metastasis and performed a genomic analysis, or comparative genomic hybridization (CGH) of the Cytokeratin... ... tumor cells that could potentially disseminate, mutate, change, and grow into another tumor. More emphasis needs to be put on the development of disseminated cells because the changes in their growth cannot be reflected by the genomic data obta ined from the primary tumor data as a result, they can not be dealt with in the same manner.The main idea of this study is to underscore the need to validate potential cellular targets for adjuvant and systemic therapies on disseminated cancer cells directly( crabby person Cell July 2003).The paper that is world discussed is Gray, J.W., Evidence emerges for early metastasis and parallel evolution of primary and metastatic tumors. Cancer Cell July 2003.Schmidt-Kittler, O. et al., From latent disseminated cells to overt metastasis genetic analysis of systemic breast cancer progression. PNAS 100, 7734 (2003).
