“…We also did not analyse the predictive value of steatosis, being overweight, tobacco, coffee, chocolate, or cannabis consumption, physical exercise, or long‐term drug use, all of which may be associated with fibrosis or the risk of PLC. However, GGT was highly associated with the risk of PLC, probably due to its association with cytotoxicity factors such as alcohol and metabolic factors . Indeed, the presence of type‐ 2‐diabetes was predictive of PLC (Table S7), although it was not associated with cirrhosis at inclusion, suggesting a mechanism independent of the progression of fibrosis.…”

Summary Background No blood test has been shown to be effective in the prediction of primary liver cancer in patients without cirrhosis. Aim To construct and internally validate two sequential tests for early prediction of liver cancer. These tests enable an algorithm which could improve the performance of the standard surveillance protocol recommended (imaging with or without AFP), limited to patients with cirrhosis. Methods We performed a retrospective analysis in prospectively collected specimens from an ongoing cohort. We designed an early sensitive high‐risk test (LCR1) that combined (using Cox model) hepatoprotective proteins (apolipoproteinA1, haptoglobin) with known risk factors (gender, age, gammaglutamyltranspeptidase), and a marker of fibrosis (alpha2‐macroglobulin). To increase the specificity, we then combined (LCR2) these components with alpha‐fetoprotein. Results A total of 9892 patients, 85.9% without cirrhosis, were followed up for 5.9 years [IQR: 4.3‐9.4]. LCR1 and LCR2 time‐dependent AUROCs were not different in construction and validation randomised subsets. Among 2027 patients with high‐LCR1 then high‐LCR2, 167 cancers (113 with cirrhosis, 54 without cirrhosis) were detected, that is 12 patients needed to screen one cancer. The negative predictive value was 99.5% (95% CI 99.0‐99.7) in the 2026 not screened patients (11 cancers without cirrhosis) higher than the standard surveillance, which detected 113 cancers in 755 patients screened, that is seven patients needed to screen one cancer, but with a lower negative predictive value 98.0% (97.5‐98.5; Z = 4.3; P < 0.001) in 3298 not screened patients (42 cancers without cirrhosis). Conclusions In patients with chronic liver disease the LCR1 and LCR2 tests identify those with a high risk of liver cancer, including in those without cirrhosis. NCT01927133.

Sorafenib, a small inhibitor of tyrosine protein kinases, is currently the standard chemotherapy drug for the treatment of advanced hepatocellular carcinoma (HCC). Although sorafenib improves the survival of HCC patients, its efficacy is not optimal and requires further improvement. Capsaicin, the major active component of chili peppers from the genus Capsicum, is not only the agonist of TRPV1 channel, but also displays antitumor activity and enhances the sensitivity of cancer cells to cytotoxic drugs. In this study, we investigated the antitumor effects of combined sorafenib and capsaicin on HCC cells in vitro and xenograft tumors. Treatment with capsaicin alone dose-dependently inhibited the proliferation of the HCC cell lines PLC/PRF/7, HuH7 and HepG2 with IC values of 137, 108 and 140.7 μmol/L, respectively. No obvious expression of TRPV1 channel was detected in the 3 HCC cell lines and TRPV1 channel blockers did not alleviate the cytotoxicity of capsaicin. By contrast, combining capsaicin and sorafenib significantly enhanced the suppression on cell proliferation, achieving a high-level synergistic effect (inhibition rates over 50%) and promoting HCC cell apoptosis. In nude mice with PLC/PRF/5 xenografts, combined administration of capsaicin and sorafenib significantly enhanced the suppression on tumor growth without apparent gross toxicity compared to either agent alone. Mechanistically, capsaicin (10-200 μmol/L) dose-dependently increased the levels of phosphorylated ERK (p-ERK) in PLC/PRF/5 cells, thus leading to enhanced sorafenib sensitivity and a synergistic suppression on the tumor cells. Taken together, our results suggest that capsaicin-increased phosphorylation of ERK contributes to the enhanced antitumor activity of sorafenib, and capsaicin may be useful in improving the efficacy of sorafenib for the treatment of HCC.
