  • People with small, slow-growing tumors may not need treatment. (medlineplus.gov)
  • Treatment for GCTs usually involves surgically removing the tumor. (medicinenet.com)
  • In some cases, additional treatment with medications or radiation could be necessary to prevent the tumor from returning. (medicinenet.com)

  • For benign tumors that are not ulcerated and do not impair the dog's normal routine, treatment may not be necessary. (merckvetmanual.com)
  • The large tumor antigen (also called the large T-antigen and abbreviated LTag or LT) is a protein encoded in the genomes of polyomaviruses, which are small double-stranded DNA viruses. (wikipedia.org)
  • Some polyomavirus LTag proteins - most notably the well-studied SV40 large tumor antigen from the SV40 virus - are oncoproteins that can induce neoplastic transformation in the host cell. (wikipedia.org)
  • SV40 Early Region and Large T Antigen in Human Brain Tumors, Peripheral Blood Cells, and Sperm Fluids from Healthy Individuals. (aacrjournals.org)
  • Anaplastic large cell lymphomas (ALCLs) are distinguished from other lymphomas by their anaplastic cytology and constant membrane expression of the CD30 antigen (an activation marker for B or T cells). (medscape.com)
  • ALCL was recognized in 1985, when tumor cells consistently demonstrated labeling by the monoclonal antibody Ki-1, a marker later shown to recognize the CD30 antigen. (medscape.com)
  • The second session is the injection of the radioactive particles/Y90 into the blood vessels supplying the tumor. (kidshealth.org)
  • For example, Wen says, oncologists have suspected the connection between tumor appearance and response to therapies targeting tumor blood vessels demonstrated in Kuo's study. (technologyreview.com)
  • This ulcerated nodule of localized primary cutaneous CD30+ anaplastic large cell lymphoma is relatively nonspecific in appearance. (medscape.com)
  • A French multicenter study of children younger than 18 years with neuroendocrine tumors of the appendix was carried out by surveying pediatric surgeons from 1988 to 2012. (oncolink.org)
  • Doctors said that the surgery was complicated since the tumour occupied the entire abdominal area. (ndtv.com)
  • Chemotherapy or radiation therapy may be used for certain tumors. (medlineplus.gov)
  • As a nano- oxygen carrier, Haemoglobin-based oxygen carriers (HBOCs) administration is a promising strategy to alleviate tumour hypoxia which may remodel TME to ameliorate radiation resistance and enable RT more effective. (bvsalud.org)
  • Chemicals, solar radiation, and viruses are just some of the things that can cause skin tumors. (merckvetmanual.com)
  • A very large radiation dose received in a short enough period of time to preclude significant repair can cause cellular walls to collapse and disrupt organ systems, producing deterministic effects such as acute radiation syndrome, cataracts, and teratogenesis (mental retardation, IQ reduction, microencephaly, stunted growth). (cdc.gov)
  • A non-functional adrenal tumor is an adrenal tumor that does not secrete hormones. (hopkinsmedicine.org)
  • A blood test can help the doctor detect any subtle, unusual hormone levels that would indicate the tumor is secreting hormones. (hopkinsmedicine.org)
  • The concentrations of these hormones are found to be higher in hormone dependent tumors, whereas in hormone independent tumors (as seen in latter stages of mammary adenocarcinoma) they tend to be lower. (ratguide.com)

  • Women who have large fibroids or pelvic tumors are at an increased risk of prolapse. (medscape.com)
  • The physical examination showed unremarkable finding except for a large pelvic mass. (hindawi.com)
  • Here we developed PUREE, which uses a weakly supervised learning approach to infer tumor purity from a tumor gene expression profile. (nature.com)
  • Overall, PUREE is a highly accurate and versatile method for estimating tumor purity and interrogating tumor heterogeneity from bulk tumor gene expression data, which can complement genomics-based approaches or be used in settings where genomic data is unavailable. (nature.com)
  • Existing methods that estimate tumor purity from a tumor gene expression profile adopt different analytical strategies (Supplementary Note 1 , 2 ). (nature.com)
  • In work described in today's issue of the Proceedings of the National Academy of Sciences , Kuo's group identified five visually discernable kinds of tumors strongly associated with particular gene-expression profiles that are tied to targeted therapies. (technologyreview.com)
