Correlation between serum ferritin and response rate and prognosis of lung cancer immunotherapy
To study the correlation between the serum ferritin level and the pathological classification, tumor stage,PD-L1 expression, disease control rate (DCR), and survival period of patients with lung cancer.
Methods
2
A total of 85 patients with lung cancer
admitted to our hospital from February 2020 to February 2021 were selected as the research subjects. All patients received immunotherapy, and the serum ferritin levels of patients before and after immunotherapy were detected. Meanwhile, according to the difference in serum ferritin levels before and after immunotherapy, the patients were divided into the increased group (31 cases) and the decreased group (54 cases). The correlation between the serum ferritin level and the pathological classification, tumor stage and PD-L1 expression level of patients was analyzed, and the DCRs and survival periods of patients with serum ferritin level ≥300 ng/mL and
<
300 ng/mL before treatment were compared, as well as the increased group and the decreased group. The survival curve of patients in each group was analyzed by the
Kaplan
-
Meier
.
Results
2
Patients with tumor stage Ⅰ to Ⅲ showed significantly lower serum ferritin levels than patients with tumor stage Ⅳ (
P
<
0.05).The DCR,3-year survival rate and progression-free survival (PFS) of patients with serum ferritin level ≥300 ng/mL were significantly lower/shorter than those of patients with serum ferritin level
<
300 ng/mL (
P
<
0.05). The DCR, 3-year survival rate and PFS of patients in the increased group were significantly lower/shorter than those in the decreased group (
P
<
0.05).
Conclusion
2
The increased serum ferritin level in lung cancer patients before treatment and the further increase after treatment are significantly associated with the reduced efficacy of immunotherapy and the shortened survival period. The combination of baseline serum ferritin levels before treatment and dynamic changes after treatment may serve as a clinical biomarker panel for predicting immunotherapy outcomes.
