This study aimed to evaluate serum thymidine kinase 1 (TK1) activity as a marker for solid tumors and more specifically in: preoperative testing for prediction of disease recurrence and survival; follow-up after surgical removal of the original tumor for early detection of disease recurrence and in monitoring therapy as a surrogate marker of tumor response.
Thymidine kinase 1 (TK1) is a metabolic enzyme catalyzing the ATP-dependent phosphorylation of thymidine to thymidine monophosphate followed by its utilization in DNA synthesis. It has been demonstrated that activity of TK1 in the serum of cancer patients corresponds to the amount of dividing tumor cells. Several clinical investigations clearly showed that abnormal TK1 levels indicate tumor growth. In breast cancer, serum TK1 was shown to predict increased risk of recurrence following surgery and may be a good marker for monitoring the response to therapy. The measurements of TK1 were useful as a prognostic and monitoring factor in patients with NSCLC. Unfortunately, all previously used assays measuring TK1 activity showed relatively low analytical sensitivity. Recently, the novel high sensitive non-radioactive TK1 assay (DiviTum) has been developed. With this assay tumour growth may be detected at an earlier stage of disease and smaller amounts of residual disease may be detected during and after therapy.

The prognostic role of targeting protein for Xklp2 (TPX2) in solid tumors has been investigated in several researches, but the results remain controversial. Here we present a meta-analysis to systemat...
Recently, several studies have reported that the long non-coding RNA cancer susceptibility 2 (CASC2) is downregulated in human solid tumors. However, as the sample size in those studies was limited, t...
Serum apolipoprotein A1 (apoA1) has been reported to be abnormally expressed in several malignancies. However, the prognostic role of apoA1 in solid tumors is still controversial. We conducted this me...
A plenty of previous researches have reported the prognostic value of CDC20 (Cell Division Cycle Protein 20) in solid tumors. Nevertheless, these researches were restricted by the small sample databas...
Scientists have identified a wide variety of challenges preventing the development of effective CAR T-cell therapies for solid tumors, but they are investigating just as many potential solutions. Prog...
An alkylating agent of value against both hematologic malignancies and solid tumors.
An internationally recognized set of published rules used for evaluation of cancer treatment that define when tumors found in cancer patients improve, worsen, or remain stable during treatment. These criteria are based specifically on the response of the tumor(s) to treatment, and not on the overall health status of the patient resulting from treatment.
A smooth, solid or cystic fibroepithelial (FIBROEPITHELIAL NEOPLASMS) tumor, usually found in the OVARIES but can also be found in the adnexal region and the KIDNEYS. It consists of a fibrous stroma with nests of epithelial cells that sometimes resemble the transitional cells lining the urinary bladder. Brenner tumors generally are benign and asymptomatic. Malignant Brenner tumors have been reported.
A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.
A group of methylazirinopyrroloindolediones obtained from certain Streptomyces strains. They are very toxic antibiotics used as ANTINEOPLASTIC AGENTS in some solid tumors. PORFIROMYCIN and MITOMYCIN are the most useful members of the group.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical re...
