Background Lung cancer is the primary cause of cancer related death worldwide, early detection of the disease contributes to early diagnosis and reduce the incidence of death from lung cancer. Therefore, an effective and non-invasive method for early diagnosis of lung cancer is urgently needed. Methods To evaluate the diagnostic performance of circulating genetically abnormal cells(CAC) in early lung cancer, a total of 63 participants who completed CAC detection by ZHUHAI SANMED BIOTECH INC. and obtained pathological results from January to December 2020 were included in our study, which were divided into 50 cases of lung cancer ,13 cases of benign lung disease. The levels of lung cancer-related markers in peripheral blood and chest computed tomography(CT) imaging characteristics of these patients were collected before pathological acquisition. ResultsThe positive rate of CAC was 90.0% in lung cancer group and 23.1% in benign lung disease group, the difference was statistically signi cant (P 0.01).The area under the receiver operating characteristic (ROC) curve of CAC was 0.837, the sensitivity was 90%, and the speci city was 76.9%.The area under the ROC curve and sensitivity were both higher than the combined or single serum tumor marker test.Conclusions This study preliminarily concludes that CAC, as a non-invasive test, has high sensitivity and speci city for early diagnosis of lung cancer, which is expected to help early detection of disease in lung cancer patients and has certain help and guiding signi cance for clinical work.
This study aimed to evaluate the risk factors for recurrence in pediatric patients with epilepsy following normal antiseizure medication (ASM) treatment and drug withdrawal. We retrospectively analyzed 80 pediatric patients who received treatment at the Qilu Hospital of Shandong University between January 2009 and December 2019 after at least 2 years of seizure-free and normal electroencephalography (EEG) before the regular drug reduction. Patients were followed-up for at least 2 years and divided into the recurrence and nonrecurrence groups based on whether relapse occurred. Clinical information was gathered, and the risk variables for recurrence were statistically analyzed. Post 2 years of drug withdrawal, 19 patients showed relapses. The recurrence rate was 23.75%, and the mean time of recurrence was 11.09 ± 7.57 months, where 7 (36.8%) were women and 12 (63.2%) were men. In all, 41 pediatric patients were followed-up until the 3rd year, of which 2 (4.9%) patients experienced a relapse. Among the remaining 39 patients without relapse, 24 were followed-up until the 4th year, and no recurrence occurred. After being monitored for >4 years, 13 patients experienced no recurrence. The differences in the history of febrile seizures, combined use of ≥2 ASMs, and EEG abnormalities after drug withdrawal between the two groups were statistically significant (p < 0.05). Multivariate binary logistic regression analysis revealed that these factors are independent risk factors for recurrence after drug withdrawal in children with epilepsy: history of febrile seizures (OR = 4.322, 95% CI: 1.262–14.804), combined ASM use (OR = 4.783, 95% CI: 1.409–16.238), and EEG abnormalities after drug withdrawal (OR = 4.688, 95% CI: 1.154–19.050). In summary, our results suggest that the probability of seizure recurrence following drug cessation may be greatly increased by a history of febrile seizures, concomitant use of ≥2 ASMs, and EEG abnormalities after drug cessation. The majority of recurrences occurred in the first 2 years following drug discontinuation, whereas the rate of recurrence was minimal thereafter.
