  • [ 3 , 4 ] Much of the increase has been due to a rise in the incidence of papillary thyroid cancer, which grew from 7.8 cases per 100,000 persons in 2003 to 15.4 cases per 100,000 persons in 2013. (medscape.com)
  • Despite the growth in the incidence of thyroid cancer, the disease's mortality rate has remained the same (0.5 deaths per 100,000). (medscape.com)
  • Nonetheless, although controversy exists, there is growing evidence that the expanded incidence of reported thyroid cancer may be due to an increase in new cases. (medscape.com)
  • Hürthle cell carcinoma of the thyroid gland is an unusual and relatively rare type of differentiated thyroid cancer. (medscape.com)
  • Liu C, Pan Y, Li Q, Zhang Y. Bioinformatics analysis identified shared differentially expressed genes as potential biomarkers for Hashimoto's thyroiditis-related papillary thyroid cancer. (medsci.org)
  • According to the literature, the pathogenesis of HT-related thyroid cancer may be due to the diffuse lymphocyte infiltration, apoptosis of thyroid epithelial cells, fibrous replacement, and follicular destruction in HT. (medsci.org)
  • However, controversy exists regarding whether HT is related to papillary thyroid cancer (PTC), which accounts for 95% of all thyroid cancer cases and has increasing prevalence worldwide. (medsci.org)
  • They look at papillary thyroid cancer, in which a radiation-induced inversion often fuses the genes for H4 and the RET receptor tyrosine kinase. (biomedcentral.com)
  • Our data raise the possibility that the development of AML may require fewer genetic alterations than other cancers and that a very limited number of biological processes may need to be altered in hematopoietic stem cells, multi-potential progenitors or committed myeloid progenitors to convert them from a normal cell to AML," the authors noted, referring to several types of immature and maturing cells that give rise to this cancer.

  • Some case reports identified MYC or MLL gene amplification performing as dmin in myeloid neoplasms. (hindawi.com)
  • What should people know about non-small lung cancers that are driven by MET mutations? (curetoday.com)
  • The second is highly MET-amplified lung cancers. (curetoday.com)
  • Small cell lung cancer (SCLC) is an aggressive neuroendocrine subtype of lung cancer that represents 13-15 % of all lung cancers [ 2 ]. (biomedcentral.com)
  • 3 HERVs also play a role in disease, and have been linked to various cancers and male infertility. (answersingenesis.org)
  • Molecular genetic abnormalities preceding, or occurring during, BC include overexpression of the BCR/ABL transcript, upregulation of the EVI1 gene, increased telomerase activity, and mutations of the tumor suppressor genes RB1, TP53, and CDKN2A. (lu.se)
  • Using whole-genome sequencing of OS, we found features of TP53 intron 1 rearrangements suggesting a unique mechanism correlated with transcription. (oncotarget.com)
  • While whole exome sequencing (WES) remains popular and effective as a method of genetically profiling different cancers, advances in sequencing technology has enabled an increasing number of whole-genome based studies. (frontiersin.org)
  • IHC is especially indicative for MMR mutations that result in truncation of the protein, such as frame shift, splice site mutations, large genomic rearrangements, and mismatch, although IHC is not always diagnostic for mismatch. (medscape.com)
