Abstract:
Objective:To evaluate the effect of preventive application of PEG-rhG-CSF on the prevention of neutropenia during concurrent chemoradiotherapy in patients with lung cancer.Methods:A total of 149 patients with lung cancer who received concurrent chemoradiotherapy at Peking University Cancer Hospital from April 2020 to April 2021 were retrospectively analyzed. There were 79 cases in the prevention group, including 48 cases of primary prevention group (preventive application of PEG-rhG-CSF in all concurrent chemoradiotherapy cycles) and 31 cases of secondary prevention group (preventive application of PEG-rhG-CSF in the concurrent chemoradiotherapy cycles after neutropenia occurred). There were 70 cases in non-prevention group. The incidence of grade 3-4 neutropenia, the completion rate of concurrent chemoradiotherapy, the rate of chemoradiotherapy dose reduction and treatment delay, and the rate of hematological toxicities related hospitalization were compared between the prevention group and the non-prevention group.Results:The incidence of grade 3-4 neutropenia in the whole group was 32.2% (48/149), including 6.3% (3/48) in the primary prevention group, 9.7% (3/31) in the secondary prevention group, and 35.7% (25/70) in the non-prevention group. The difference was statistically significant ( χ2=17.81, P<0.001) in the incidence of grade 3-4 neutropenia. The incidence of febrile neutropenia was 3.4% (5/149) in the whole group, but none of them occurred in the primary prevention group. The full completion rate of concurrent chemotherapy was 96.2% (76/79) in the prevention group, which was significantly higher than 82.9% (58/70) in the non-prevention group ( χ2=7.30, P=0.007). The incidence of treatment delayed and dose reduction of chemoradiotherapy was 19.0% (15/79) in the prevention group and 40.0% (28/70) in the non-prevention group, and the difference was statistically significant ( χ2=7.98, P=0.005). Conclusions:The preventive application of PEG-rhG-CSF can effectively reduce the incidence of neutropenia and better ensure the concurrent chemoradiotherapy in lung cancer patients on schedule.
