OBJECTIVES@#To study the early clinical efficacy of combined therapy of stage 4 neuroblastoma.@*METHODS@#A retrospective analysis was performed on the medical data and follow-up data of 14 children with stage 4 neuroblastoma who were diagnosed in Hong Kong University-Shenzhen Hospital from January 2016 to June 2021.@*RESULTS@#The median age of onset was 3 years and 7.5 months in these 14 children. Among these children, 9 had positive results of bone marrow biopsy, 4 had N-Myc gene amplification, 13 had an increase in neuron-specific enolase, and 7 had an increase in vanilmandelic acid in urine. Based on the results of pathological examination, differentiated type was observed in 6 children, undifferentiated type in one child, mixed type, in one child and poorly differentiated type in 6 children. Of all the children, 10 received chemotherapy with the N7 regimen (including 2 children receiving arsenic trioxide in addition) and 4 received chemotherapy with the Rapid COJEC regimen. Thirteen children underwent surgery, 14 received hematopoietic stem cell transplantation, and 10 received radiotherapy. A total of 8 children received Ch14.18/CHO immunotherapy, among whom 1 child discontinued due to anaphylactic shock during immunotherapy, and the other 7 children completed Ch14.18/CHO treatment without serious adverse events, among whom 1 child was treated with Lu177 Dotatate 3 times after recurrence and is still undergoing chemotherapy at present. The median follow-up time was 45 months for all the 14 children. Four children experienced recurrence within 2 years, and the 2-year overall survival rate was 100%; 4 children experienced recurrence within 3 years, and 7 achieved disease-free survival within 3 years.@*CONCLUSIONS@#Multidisciplinary combined therapy is recommended for children with stage 4 neuroblastoma and can help them achieve better survival and prognosis.

Objective:To summarize the clinical characteristics, common images, pathogens, and gene mutation types of chronic granulomatosis disease (CGD) in 19 children.Methods:The clinical manifestations, laboratory findings, treatment, and prognosis of 19 patients diagnosed with CGD in Hong Kong University-Shenzhen Hospital from December 2012 to December 2018 were analyzed.Results:The 19 patients were all males and confirmed as CGD by the dihydrorhodamine test and gene sequencing.The age of the first infection was mostly 1 month after birth(13 cases), and the age of clinical diagnosis ranged from 2 months to 10 years.Sixteen mothers were carriers.The patients presented with pulmonary fungal infection (19/19 cases), Bacillus Calmette Guerin (BCG)-osis (14/19 cases), lymphadenitis (14/19 cases), perianal abscess (9/19 cases), skin abscess (5/19 cases) and ulcerative colitis (2/19 cases). There were 59 positive cultures.Pathogens included fungi (9 cases), Klebsiella pneumonia (8 cases), mycobacteria (7 cases), Streptococcus Viridans (5 cases), Escherichia coli (3 cases), gram-positive bacteria (3 cases), Staphylococcus aureus (3 cases), and Burkholderia cenocepacia (2 cases). Gene mutations were found in all 19 patients, including 17 cases of CYBB, 1 case of CYBA and 1 case of NCF2.The type of mutations included nonsense mutations (6 cases), deletion mutations (5 cases, including 2 large fragment deletions), splice mutations (3 cases) and missense mutations (5 cases). Five mutations were novel.Splice mutations in 3 cases often led to skin abscess, perianal abscess and lymphadenitis.Two patients with large deletion mutations had more serious infection than other patients. Conclusions:In China, CGD is characterized with pulmonary infection and disseminated BCG-osis.Mycobacteria are common pathogens of CGD, and fungi are dominant pathogens of CGD.The most common infection is respiratory infection. Klebsiella pneumonia and Escherichia coli often lead to perianal abscess.The relationship between gene mutation types and clinical phenotypes requires further verification by big data.
