The relationship between peripheral neuropathy and efficacy in second-line chemotherapy for unresectable advanced gastric cancer: a prospective observational multicenter study protocol (IVY)

Serum basic fibroblast growth factor and interleukin-1β predict the effect of first-line chemotherapy in patients with advanced gastric cancer

BACKGROUND

The incidence and mortality rates of gastric cancer in China are the second-highest in the world, and most patients with gastric cancer lose their chance of surgery by the time of their diagnosis.

AIM

To explore the predictive potential of serum basic fibroblast growth factor and interleukin-1β levels for the effect of first-line chemotherapy in patients with advanced gastric cancer.

METHODS

From the gastric cancer patients admitted to our hospital from May 2019 to April 2023, 84 patients were selected and randomly and equally assigned to the experimental or control group. The FLOT group received the FLOT chemotherapy regimen (composed of oxaliplatin + calcium folinate + fluorouracil + paclitaxel), while the SOX group received the SOX chemotherapy regimen (composed of oxaliplatin + tiga capsules). The clinical efficacy, tumor marker levels, adverse reactions, and survival rates of the two groups were compared 7 days after the end of the relevant treatments.

RESULTS

The target effective rate of the FLOT group was 54.76%, which was much higher than that of the SOX group (33.33%; P < 0.05). After treatment, both the groups demonstrated lower levels of cancer antigen (CEA), carbohydrate antigen 199 (CA199), and peptide tissue antigen (TPS). For several patients before treatment (P < 0.05). Third and fourth grades. In terms of adverse reactions, the level of white blood cells in both the groups was lower. Moreover, the incidence of hand-foot skin reactions in these two study groups was lower (P < 0.05), while those of peripheral neuritis, vomiting, diarrhea, and abnormal liver function were significant (P < 0.05). No statistically significant difference was noted between the two groups (P < 0.05). The 1-year survival rate was higher in the FLOT group (P < 0.05).

CONCLUSION

The FLOT regimen was effective in reducing the serum CEA, CA199, and TPS levels as well as in improving the 1-year survival rate of patients with good tolerability, making it worthy of clinical promotion and application.

miR-144-3p increases radiosensibility of gastric cancer cells by targeting inhibition of ZEB1

PURPOSE

This study set out to probe into the effect and mechanism of miR-144-3p on radiosensitivity of gastric cancer (GC) cells.

METHODS

Cancer tissue and paracancerous tissue of GC patients admitted to our hospital were collected, their miR-144-3p expression was tested, GC cells were transfected, and survival and biological behavior of those cells under radiation were detected.

RESULTS

After detection, miR-144-3p expression was down-regulated in GC tissue, while ZEB1 was up-regulated. There was no remarkable difference in the survival fraction of cells in each group before receiving radiation, but that of tumor cells decreased obviously (p < 0.05) after radiation exposure. Survival fraction of cells overexpressing miR-144-3p or silencing ZEB1 decreased more obviously, while the inhibition of miR-144-3p or overexpressing ZEB1 was weaker. Biological behavior of cells under 6 Gy radiation was detected. It was found that miR-144-3p overexpression or silencing ZEB1 dramatically inhibited the proliferation activity of GC cells under 6 Gy radiation, increased the levels of pro-apoptotic Bax and caspase-3 proteins (p < 0.05) and decreased the anti-apoptotic protein Bcl-2 level (p < 0.05), resulting in an increase in the apoptosis rate of cells. miR-144-3p was confirmed to be ZEB1 targeting site by dual luciferase report. Moreover, rescue experiments prove that it can increase the radiosensitivity of GC cells by regulating ZEB1 expression.

CONCLUSION

miR-144-3p expression was down-regulated in GC, and it can increase the radiosensitivity of those cells by inhibiting ZEB1 expression.
