ABSTRACT
Objective:To investigate the efficacy and safety of camrelizumab combined with stereotactic body radiation therapy (SBRT) in the treatment of advanced oligometastaticnon-small cell lung cancer (NSCLC).Methods:Eighty-six patients with advanced oligometastatic NSCLC who met the inclusion and exclusion criteria from March 2020 to August 2021 in the Second People′s Hospital of Yibin were divided into the control group (43 cases) and the treatment group (43 cases) according to the random number table method, the control group was given camrelizumab combined with conventional radiotherapy, and the treatment group was given camrelizumab combined with SBRT. After 8 weeks of treatment, the efficacy of the two groups was evaluated, the occurrence of side effects in the two groups was counted, the serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment anti-21-1 (CYFRA21-1)] levels were detected.Results:The objective effective rate of the treatment group was significantly higher than that of the control group:: 72.09% (31/43) vs. 51.16%(22/43), the difference was statistically significant ( P<0.05); the incidence of radiation pneumonia in the treatment group was significantly lower than that in the control group: 4.65% (2/43) vs. 18.60% (8/43), the difference was statistically significant ( P<0.05), and there was no significant difference in the incidences of other side effects such as cutaneous capillary endothelial proliferation (CCEP), liver damage, hypothyroidism, and radiation esophagitisbetween the treatment group and the control group ( P>0.05); the levels of serum CEA, SCC-Ag, CYFRA21-1after treatmentin the two groups were significantly lower than those before treatment, treatment group: treatmentgroup: (8.81 ± 4.82) ng/L vs. (81.67 ± 50.88) ng/L, (1.13 ± 0.55) ng/L vs. (1.56 ± 1.03) ng/L and (2.92 ± 0.99) ng/L vs. (4.63 ± 1.39) ng/L, controlgroup: (30.49 ± 19.44) ng/L vs. (89.91 ± 50.10) ng/L, (1.56 ± 1.23) ng/L vs. (1.86 ± 1.33) ng/L and (4.01 ± 2.10) ng/L vs. (5.03 ± 3.44) ng/L. and the levels after treatment in the treatment group were significantly lower than those in the control group, and there were statistical differences ( P<0.05). Conclusions:Camrelizumab combined with SBRT treatment for patients with advanced oligometastatic NSCLC can effectively reduce the levels of serum CEA, SCC-Ag, CYFRA21-1, and significantly improve the short-term efficacy, with relatively low incidence of toxic side effects.
ABSTRACT
BackgroundThe coronavirus disease 2019 (Covid-19) spreads rapidly around the world. ObjectiveTo evaluate the association between comorbidities and the risk of death in patients with COVID-19, and to further explore potential sex-specific differences. MethodsWe analyzed the data from 18,465 laboratory-confirmed cases that completed an epidemiological investigation in Hubei Province as of February 27, 2020. Information on death was obtained from the Infectious Disease Information System. The Cox proportional hazards model was used to estimate the association between comorbidities and the risk of death in patients with COVID-19. ResultsThe median age for COVID-19 patients was 50.5 years. 8828(47.81%) patients were females. Severe cases accounted for 20.11% of the study population. As of March 7, 2020, a total of 919 cases deceased from COVID-19 for a fatality rate of 4.98%. Hypertension (13.87%), diabetes (5.53%), and cardiovascular and cerebrovascular diseases (CBVDs) (4.45%) were the most prevalent comorbidities, and 27.37% of patients with COVID-19 reported having at least one comorbidity. After adjustment for age, gender, address, and clinical severity, patients with hypertension (HR 1.55, 95%CI 1.35-1.78), diabetes (HR 1.35, 95%CI 1.13-1.62), CBVDs (HR 1.70, 95%CI 1.43-2.02), chronic kidney diseases (HR 2.09, 95%CI 1.47-2.98), and at least two comorbidities (HR 1.84, 95%CI 1.55-2.18) had significant increased risks of death. And the association between diabetes and the risk of death from COVID-19 was prominent in women (HR 1.69, 95%CI 1.27-2.25) than in men (HR 1.16, 95%CI 0.91-1.46) (P for interaction = 0.036). ConclusionAmong laboratory-confirmed cases of COVID-19 in Hubei province, China, patients with hypertension, diabetes, CBVDs, chronic kidney diseases were significantly associated with increased risk of death. The association between diabetes and the risk of death tended to be stronger in women than in men. Clinicians should increase their awareness of the increased risk of death in COVID-19 patients with comorbidities.
