Abstract

BACKGROUND: Colorectal cancer (CRC) is an important cause of cancer-related death. Prediction of recurrence is an important issue in the treatment of disease, particularly for stage II patients. The level of telomere-specific reverse transcriptase (hTERT), the catalytic component of the telomerase complex, increases along with CRC progression, but its prognostic value is still unclear. METHODS: One hundred and thirty-seven CRC patients were studied for hTERT expression in tumour cells by real-time PCR. hTERT level was evaluated as a prognostic factor of overall survival (OS) in all patients and of disease recurrence in a subgroup of 50 stage II patients. RESULTS: The median hTERT level was 93.8 copies (interquartile range 48-254). Patients with high hTERT levels (above the median) showed a significantly worse survival than those with low hTERT levels (below the median; log-rank test P<0.0001; hazard ratio (HR)=3.30 (95% confidence interval (CI) 1.98-5.52); P<0.0001). The negative prognostic value of high hTERT level is independent of the pathological stage and microsatellite instability (HR=2.09 (95% CI 1.20-3.64), P=0.009). Moreover, in stage II CRC, high hTERT levels identified patients with a higher risk of disease recurrence (HR=3.06 (95% CI 1.03-9.04), P=0.043) and death (HR=3.24 (95% CI 1.37-7.71), P=0.008). CONCLUSION: hTERT level is an independent prognostic marker of OS in CRC patients. In addition, assessment of hTERT level could improve stratification of stage II CRC patients for the risk of disease recurrence.

  • Bertorelle et al. showed that stage II CRC patients with lower levels of hTERT had better overall survival, while its presence at higher levels was correlated with a poor response to chemotherapy (as an independent prognostic factor) and with a higher risk of disease recurrence and death.

    “Bertorelle et al. showed that stage II CRC patients with lower levels of hTERT had better OS, while its presence at higher levels was correlated with a poor response to chemotherapy (as an independent prognostic factor) and with a higher risk of disease recurrence and death [207].”
  • Elevated levels of hTERT have been linked to overall survival in CRC patients.

    “Additionally, elevated levels of hTERT have been linked to OS in CRC patients [207].”
  • Ample evidence supports telomerase as a useful marker for monitoring and predicting outcomes in CRC.

    “In summary, ample evidence supports telomerase as a useful marker for monitoring and predicting outcomes in CRC [207].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
