ABSTRACT
Objective:To summarize and analyze the clinical characteristics, treatment and prognosis of superior vena cava syndrome (SVCS) with malignant tumors in children, and to improve the understanding of its clinical management.Methods:Clinical data of 50 children with SVCS combined with malignant tumors treated in the First Affiliated Hospital of Zhengzhou University from November 2010 to May 2022 were analyzed retrospectively.The pathological types, clinical manifestations, imaging examination, treatment and prognosis were summarized.The overall survival (OS) rate and event-free survival (EFS) rate were evaluated by Kaplan-Meier method.Results:Among the 50 cases, 38 were males and 12 were females, with a male/female ratio of 3.2∶1.0.The median onset was 12.5 (8.0, 14.5) years, and the most common onset occurred in adolescence (66.0%, 33/50). Cough (80.0%, 40/50) was the most common clinical manifestation, followed by face and neck edema (66.0%, 33/50), chest tightness (56.0%, 28/50) and dyspnea (50.0%, 25/50). All the 50 cases were confirmed by histopathological examination, 39 cases(78.0%) were diagnosed as non-Hodgkin′s lymphoma (NHL). NHL was the most common malignant tumor, of which T-lymphoblastic lymphoma (T-LBL) accounted for 74.4%(29/39). All the 50 cases were examined by CT examination, involving 42 cases (84.0%) detected with mediastinal masses.Pleural effusion (86.0%, 43/50) and pericardial effusion (70.0%, 35/50) were common imaging findings.The 3-year OS rate and EFS rate of them were 59.7% and 57.9%, respectively.The 3-year OS rate and EFS rate of the 39 children with NHL were 62.9% and 60.9%, respectively.Conclusions:Children with malignant tumors complicated with SVCS are featured by the acute onset, rapid progress and poor prognosis.NHL is the most common cause, especially T-LBL.Cough, edema of face and neck, chest tightness and dyspnea are common clinical manifestations.Early detection and treatment contribute to save children′s lives.
ABSTRACT
Objective:To investigate the clinical features and long-term prognosis of pediatric acute lymphoblastic leukemia (ALL) with renal involvement as the initial manifestation, thus enhancing the diagnostic and therapeutic efficacy.Methods:Twenty-four cases of pediatric ALL with renal involvement as the initial manifestation treated in the First Affiliated Hospital of Zhengzhou University from March 2013 to March 2019 were analyzed retrospectively, and their clinical characteristics were analyzed.According to renal imaging examination findings, they were divided into abnormal group and normal group.The differences in clinical features between the two groups were compared, and the cumulative survival rate was evaluated by Kaplan-Meier method.Results:Among 1 030 newly treated cases of pediatric ALL, 24 cases(2.33%) had renal involvement as the initial manifestation, involving 20 males and 4 females, with a male/female ratio of 5∶1 and the median age of 4.3 years (1.3-14.0 years). There were 16 cases of superficial lymph node enlargement and 21 cases of hepatosplenomegaly.Immature cells in peripheral blood were found in 15 cases.Nine cases were examined with abnormal renal imaging, involving 8 cases returned normal after chemotherapy, and 1 died of renal failure.At the end of follow-up on August 1, 2020, there were 9 cases of bone marrow relapse, 11 survival cases, 10 death cases and 3 cases of loss to follow-up.There were no significant differences in the sex, age, immunophenotype, organ infiltration and urinary protein between the two groups (all P>0.05). The proportion of high creatinine level and intramedullary recurrence rate in the abnormal group were significantly higher than those in the normal group [55.6%(5/9 cases) vs.0(0/15 cases), P=0.003; 66.7%(6/9 cases) vs.20.0%(3/15 cases), P=0.036]. The survival analysis indicated that the 3-year cumulative survival in the abnormal group was significantly lower than that of normal group (17.3% vs.72.7%, χ2=4.047, P< 0.05). Conclusions:For children with unexplained renal involvement as the initial manifestation, clinicians should consider the possibility of leukemic renal infiltration or nephrogenic lymphoma.Physical examinations of the liver, spleen and lymph nodes, morphological analysis of peripheral blood cells, bone marrow examination and renal biopsy are important to make a definite diagnosis in time.Children with imaging abnormalities caused by leukemic renal infiltration are more likely to relapse and have a lower survival rate, which may be a poor prognostic factor for ALL.
ABSTRACT
Objective:To discuss whether platelet distribution width (PDW) can effectively predict the prognosis of neuroblastoma (NB).Methods:The clinical data of 67 NB patients in the First Affiliated Hospital of Zhengzhou University between January 2014 and January 2018 were retrospectively analyzed.They were divided into low PDW group and high PDW group according to the PDW level, and the differences in clinical indicators between the 2 groups were compared.The prognostic effects of PDW were assessed by using the Kaplan- Meier method and Cox regression model. Results:Among the 67 patients, 41 cases were male, 26 cases were female, with the ratio of male to female being 1.58∶1.00, and the average age was 44 months (2-156 months). Five cases were in stage Ⅰ, 1 case in stage Ⅱ, 15 cases in stage Ⅲ and 46 cases in stage Ⅳ.At the first time of diagnosis, there were 14 cases with age ≤ 18 months, 53 cases with age > 18 months, 47 cases with neuron specific enolase (NSE) level ≥ 100 μg/L, 20 cases with NSE level<100 μg/L.The median follow-up time was 20.4 months.At the end of follow-up, 35 cases died and 32 cases survived.There was no statistical difference in age, gender, primary site of tumor, tumor stage and mean platelet volume between the low PDW group and the high PDW group (all P>0.05). The proportion of high-risk patients, the level of NSE, bone marrow metastasis rate, MYCN gene amplification rate and the red blood cell distribution width in the high PDW group were significantly higher than those in the low PDW group, but the high PDW group had a lower level of thrombocytocrit than the low PDW group, and the differences were statistically significant(all P<0.05). Survival analysis revealed that the 2-year overall survival of the low PDW group was significantly higher than that of the high PDW group (69.8% vs.25.3%, χ2=15.761, P<0.05). Univariate analysis showed that NSE ( HR=6.606, 95% CI: 2.018-21.620), MYCN gene ( HR=1.977, 95% CI: 0.794-4.919), tumor risk stratification ( HR=5.926, 95% CI: 1.416-24.794), PDW ( HR=4.036, 95% CI: 1.957-8.322), and red blood cell distribution width ( HR=1.120, 95% CI: 1.005-1.249) were the adverse factors affecting the overall survival, and thrombocytocrit was a protective factor for the prognosis of NB.Multivariate analysis indicated that PDW was an independent risk factor of NB ( HR=2.524, 95% CI: 1.017-6.264, P=0.046). Conclusions:There is a good consistency between the increase of PDW and the known prognostic risk factors, elevated tumor markers and bone marrow metastasis.Increased PDW is associated with poor prognosis in NB patients, and PDW is an independent risk factor for the poor prognosis of NB.
