RESUMO

Objective To investigate the dynamic change and its clinical significance of serum thymidine kinase 1 (STK1) in patients with non-small-cell lung cancer (NSCLC) when undergoing 4 cycles of chemotherapy. Methods We detected STK1 levels of 59 patients with NSCLC throughout 4 cycles of chemotherapy using Enhanced Chemiluminescence Western Blot and analyze its relationship with chemotherapy responses . Results STK1 levels with different chemotherapy regimens had no significant difference. STKK1 levels in patients with effective response were significantly lower after 4 cycles of chemotherapy. STK1 levels in patients with effective response were significantly lower than those in non-responders throughout 4 cycles of chemotherapy. The positive rates of STK1 in those with effective response were lower than those in non-responders after the last two cycles of chemotherapy. STK1 levels between lung squamous carcinoma and lung adenocarcinoma had no significant difference. Conclusion The detection of the changes of serum TK1 in patients with NSCLC undergoing chemotherapy is useful in evaluating the effect of chemotherapy and the later therapeutic schedule.

RESUMO

Background and purpose: The position of thymidine kinase 1 (TK1) expression during cell division is in the cytoplasm. It is a catalytic enzyme to convert deoxythymidine into thymidylate. It is the key enzyme of pyrimidine salvage pathway. The aim of this study was to analyze the serum expression level of TK1 in patients with breast cancer, and explore the application of serum TK1 test in clinical assessments of diagnosis, treatment and prognosis for breast cancer. Methods: Patient data were collected from the patients admitted in Comprehensive Breast Health Center at Rui Jin Hospital. Chemiluminesence dot blot assay was used to detect serum TK1 levels in 145 breast cancer patients and 55 patients with breast ifbroadenoma. The correlations of serum TK1 levels with breast tumor biological behavior was further studied. Results:Serum TK1 expression levels was signiifcantly increased in breast cancer patients [(2.749±0.122)pmol/L] when compared to breast fibroadenoma patients[(1.319±0.126)pmol/L, P0.05), different tumor grades (P=0.453) and different tumor size (P=0.908). Preoperative imaging results including breast ultrasound, breast mammography and breast magnetic resonance were analyzed by assessments of BI-RADS category, and serum TK1 levels in patients with different BI-RADS categories were studied. Serum TK1 levels in patients with breast ultrasound BI-RADS categories 4C-6 were signiifcantly higher than those with category 0-4B (P0.05). Most patients were followed up in our outpatient department for about 2 years. No progression-free survival differences were found in 2years. Conclusion:Serum TK1 test might be a potential tool for screening, prognosis determination and effect evaluations of targeted therapy in breast carcinoma.
