ABSTRACT
Objective:To compare the efficacy of lateral elbow dislocation approach with non-dislocation approach for open reduction and internal fixation of distal humeral coronal fracture.Methods:A retrospective cohort study was used to analyze the clinical data of 26 patients with distal humeral coronal fracture admitted to Qilu Hospital (Qingdao) of Shandong University from January 2018 to October 2021, including 10 males and 16 females, aged 15-80 years [(51.6±4.9)years]. According to Dubberley classification, there were 10 patients with type 2A, 5 with type 2B, 6 with type 3A and 5 with type 3B. Overall, 12 patients were operated via lateral elbow dislocation approach (dislocation approach group) and 14 via lateral elbow non-dislocation approach (non-dislocation approach group). The operation time, intraoperative bleeding volume, incision healing, three-dimensional CT assessment of the reduction within one week after surgery (separation or step>2 mm as poor), Mayo elbow performance score (MEPS) at 3 months after surgery and fracture healing at the last follow-up were recorded in both groups. Complications were also compared between the two groups.Results:All patients were followed up for 3-18 months [(10.5±3.3)months]. The operation time was (146.9±15.5)minutes in dislocation approach and (122.7±11.1)minutes in non-dislocation approach group ( P>0.05). The intraoperative bleeding volume was (113.3±9.7)ml in dislocation approach and (112.9±10.1)ml in non-dislocation approach group ( P>0.05). All incisions healed uneventfully in stage I. All patients had good reduction in dislocation group, while only 7 patients had good reduction and the other 7 patients presented a separation or step>2 mm in non-dislocation group ( P<0.05). The MEPS was (90.0±1.4)points in dislocation approach group at 3 months after surgery, including 9 patients being rated as excellent and 3 good, with the excellent and good rate of 100%. In constrast, the MEPS was (78.9±2.9)points in non-dislocation approach group at 3 months after surgery, including 5 patients being rated as excellent, 4 good, 4 fair and 1 poor, with the excellent and good rate of 64.3% ( P<0.05). All fractures were healed at the last follow-up. In non-dislocation approach group, osteoarthritis occurred in 7 patients, including 3 with screw protrusion, 2 with heterotopic ossification and 2 of advanced age with osteophyte formation around the joint. In dislocation approach group, osteoarthritis occurred only in 2 patients of advanced age, showing osteophyte formation around the elbow joint, with no screw cutting or heterotopic ossification. Conclusion:For distal humeral coronal fracture, the lateral elbow dislocation approach is able to provide complete exposure of the articular surface, obtain anatomic reduction, restore elbow function and reduce complications when compared with the non-dislocation approach.
ABSTRACT
Objective:To investigate the effect of enteral nutrition on hematological complications in children with malignant solid tumors during chemotherapy.Methods:A total of 103 children with malignant solid tumor admitted to our hospital from March 2020 to December 2020 were enrolled in the study. The children were randomly divided into enteral nutrition group ( n=51) and control group ( n=52). Children in enteral nutrition group were given enteral nutrition support on the basis of routine diet, while children in control group were only given routine diet. The levels of leukocytes, neutrophils, hemoglobin and platelets in peripheral blood of children during chemotherapy were analyzed. The incidence of infection and the transfusion of red blood cells and platelets after chemotherapy were documented and compared between two groups. Results:The levels of white blood cells, neutrophils, hemoglobin and platelets before chemotherapy were significantly higher than those after chemotherapy both in enteral nutrition group ( Z=-5.91, -5.59, -5.54, -5.66, all P<0.05) and in control group ( Z=-6.14, -5.84, -5.75, -4.75, all P<0.05). The overall hemoglobin levels in enteral nutrition group before and after chemotherapy was significantly higher than those in control group ( t=5.68, 5.62, P<0.05), and there were no significant differences in the levels of white blood cells, neutrophils and platelets between the two groups before chemotherapy ( Z=-0.71, -0.12, -1.29, all P>0.05) and after chemotherapy ( Z=-0.39, -0.86, -0.94, all P>0.05). Compared with the control group, the degree of anemia during chemotherapy was significantly improved in enteral nutrition group (χ2=10.45,6.12, all P<0.05), but there was no significant difference in the reduction degree of white blood cells, neutrophils and platelets between the two groups (before chemotherapy: χ2=1.17, 0.10, 0.49; after chemotherapy: χ2=0.18, 1.10, 0.97, all P>0.05). The number of children receiving red blood cell transfusion in enteral nutrition group was significantly lower than that in control group (χ2=14.06, P<0.05), and there was no significant difference in the number of children with infection and platelet transfusion between the two groups (χ2=1.20, 0.29, all P>0.05).There was no significant difference in the duration of neutrophil deficiency between enteral nutrition group and control group ( t=-1.75, P>0.05). Conclusion:Enteral nutrition support can significantly improve the hemoglobin level in children during chemotherapy, effectively alleviate the severity of anemia, and reduce the incidence of red blood cell transfusion after chemotherapy, which has high clinical application value.
ABSTRACT
Parkin, an E3 ubiquitin ligase, plays a role in maintaining mitochondrial homeostasis through targeting damaged mitochondria for mitophagy. Accumulating evidence suggests that the acetylation modification of the key mitophagy machinery influences mitophagy level, but the underlying mechanism is poorly understood. Here, our study demonstrated that inhibition of histone deacetylase (HDAC) by treatment of HDACis activates mitophagy through mediating Parkin acetylation, leading to inhibition of cervical cancer cell proliferation. Bioinformatics analysis shows that Parkin expression is inversely correlated with HDAC2 expression in human cervical cancer, indicating the low acetylation level of Parkin. Using mass spectrometry, Parkin is identified to interact with two upstream molecules, acetylase acetyl-CoA acetyltransferase 1 (ACAT1) and deacetylase HDAC2. Under treatment of suberoylanilide hydroxamic acid (SAHA), Parkin is acetylated at lysine residues 129, 220 and 349, located in different domains of Parkin protein. In in vitro experiments, combined mutation of Parkin largely attenuate the interaction of Parkin with PTEN induced putative kinase 1 (PINK1) and the function of Parkin in mitophagy induction and tumor suppression. In tumor xenografts, the expression of mutant Parkin impairs the tumor suppressive effect of Parkin and decreases the anticancer activity of SAHA. Our results reveal an acetylation-dependent regulatory mechanism governing Parkin in mitophagy and cervical carcinogenesis, which offers a new mitophagy modulation strategy for cancer therapy.
ABSTRACT
Objective:To compare reconstruction of acromioclavicular ligament versus internal fixation of acromioclavicular joint with clavicle hook plate in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular dislocation by reconstruction of coracoclavicular ligament with suture anchor.Methods:A retrospective analysis was conducted of the 56 patients who had been treated for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation from January 2015 to June 2019 at Department of Orthopaedic Trauma, Qilu Hospital of Shandong University (Qingdao). Of them, 26 were treated by reconstruction of coracoclavicular ligament with suture anchor plus reconstruction of acromioclavicular ligament (reconstruction group) and 30 by reconstruction of coracoclavicular ligament with suture anchor plus internal fixation of acromioclavicular joint with clavicle hook plate (plate group). The 2 groups were compared in terms of operation time, intraoperative blood loss, Constant-Murley score and Subjective Shoulder Rating System (SSRS) score at the last follow-up, and complications.Results:The 2 groups were comparable because there were no significant differences between them in the baseline data before operation ( P>0.05). The reconstruction group was followed up for 6 to 15 months (average, 7.9 months) while the plate group for 7 to 18 months (average, 11.3 months). The average operation time was (79.9±12.6) min for the reconstruction group and (69.1±8.5) min for the plate group, showing a significant difference ( P<0.05). No significant difference was found between the 2 groups in the intraoperative blood loss [(68.5±19.1) mL versus (65.0±16.6) mL] ( P>0.05). The differences were statistically significant between the 2 groups in Constant-Murley score (87.9±3.4 for the reconstruction group versus 91.9±3.5 for the plate group) and in SSRS score (85.1±4.1 for the reconstruction group versus 88.6±3.0 for the plate group) ( P<0.05). All the wounds healed well in the reconstruction group except for one patient who reported numbness around the wound which disappeared spontaneously 3 months postoperation. In the plate group, incision infection occurred in 2 cases, the redness and swelling in one which responded to dressing change 3 weeks later and numbness around the incision in one which was recovered 5 months after operation. Conclusions:Both surgical procedures can achieve good to excellent clinical outcomes. Although reconstruction of both acromioclavicular and coracoclavicular ligaments takes more operation time, it may lead to better Constant-Murley and SSRS scores and fewer complications, and spare secondary operation.
ABSTRACT
Objective:To explore the risk factors for disease progression and the prognosis with different disease events in a historical cohort of 56 pediatric patients with head and neck rhabdomyosarcoma (HNRMS).Methods:From June 1, 2013 to June 30, 2019, 56 pediatric patients diagnosed as HNRMS treated in the Department of Pedia-trics, Beijing Tongren Hospital, Capital Medical University were recruited in the present study.Clinical data, including general information about the diagnosis, treatment, prognostic factors, and follow-up results were collected.Patients were divided into non disease-progression (NPD) groups, including non-event (NE) group and disease-relapse (RD) group, and disease-progression (PD) group based on the disease event.Clinical data and the prognosis in NE group, RD group and PD group were compared.Risk factors for disease progression in pediatric patients with HNRMS were further analyzed by univariate and multivariate analyses of NPD group and PD group.Results:The median follow-up time of all 56 patients was 31.8 months (3.5-74.6 months). There were 30, 12, and 14 patients in NE group, RD group and PD group, respectively.The estimated 5-year overall survival rate was 100.0%, 82.5%, and 11.9% in NE group, RD group and PD group, respectively, which was statistically significant ( P<0.001). Compared with those of NE group, significantly higher rates of patients with a minimum tumor size of 5 cm ( P=0.008) and non-initial radiation therapy ( P=0.001) were detected in PD group.In addition, a significantly higher rate of patients with a minimum tumor size of 5 cm ( P=0.002), and more advanced postoperative pathological stage ( H=12.982, P=0.009) and risk of disease severity( H=18.679, P<0.001) were detected in PD group than those of RD group.The univariate analysis demonstrated that tumor size > 5 cm, alveolar rhabdomyosarcoma, non-initial radiation therapy, advanced postoperative pathological stage and high risk of disease severity were significant risk factors for disease progression of HNRMS.The multivariate analysis result showed that tumor size > 5 cm ( OR=6.75, 95% CI: 1.02-44.78), alveolar rhabdomyosarcoma ( OR=7.10, 95% CI: 1.08-46.57), and non-initial radiation therapy ( OR=15.26, 95% CI: 2.38-97.70) were independent risk factors for disease progression of HNRMS. Conclusions:Pediatric patients with HNRMS in disease progression have a significantly worse overall survival rate, and their prognosis quite differs from those with disease relapse or non-disease events.A minimum tumor size of 5 cm, alveolar rhabdomyosarcoma and non-initial radiation therapy are independent risk factors for disease progression of HNRMS.Pediatric patients with disease progression of HNRMS are susceptible to advanced pathological stage and risk of disease severity.

There were 335 affected eyes, of which 304 counts were in the intraocular stage (90.7%), most commonly in stage D (146 counts, 43.6%); 26 counts (7.7%) in the extraocular stage, mainly invading the optic nerve and/or optic nerve stump; 5 counts (1.5%) in the metastasis stage.(2) Survival analysis: the medical follow-up continued to March 31, 2020, with a median follow-up time of 67 months.There were 2 cases with a loss of follow-up, 21 relapsed cases, and 19 death cases, with the overall survival rate being 91.2%.According to Kaplan-Meier survival analysis, the expected 5-year survival rate was 91.1%; the survival rate was 96.2% in the intraocular stage and 73.1% in the extraocular stage.All 5 cases died during the distant metastasis stage, and the difference was statistically significant ( χ2=7.492, P<0.001); there was also a statistical difference in the survival rate between the monocular disease (95.9%) and binocular disease (87.3%) ( χ2=4.335, P=0.023). (3) Eyeball removal and eye protection: the eye protection rate of 217 children was 68.9%, 100.0% in stage A, B and C, 80.1% in stage D and 35.1% in stage E, which showed significant differences ( χ2=6.573, P=0.004). There were 35 children who underwent eye extraction before chemotherapy and 67 cases after chemotherapy, among which the difference was statistically significant ( χ2=6.076, P=0.012) in eye removal rates before and after chemotherapy in stage D and E(6 and 11 cases before chemotherapy, 22 and 36 cases after chemotherapy). (4) Adverse reactions: according to the World Health Organization′s classification of adverse reactions to chemotherapy, there were 26 cases in grade 0 (12.0%), 98 cases in grade Ⅰ (45.1%), 59 cases in grade Ⅱ (27.2%), 23 cases in grade Ⅲ (10.6%), and 11 cases in grade Ⅳ (5.1%), mainly manifested as bone marrow suppression after chemotherapy (132 cases). No second tumors appeared, and only 4 cases had transient hearing abnormalities, which returned to the normal state in the subsequent review. Conclusions:Infantile RB has its own characteristics.Such factors as different eye types and different clinical stages can affect the prognosis of children.The survival rate of such children can be improved significantly and the rate of eyeball removal can be reduced after treatment.
ABSTRACT
Objective:To summarize the clinical characteristics of infantile fibrosarcoma(IFS) and analyze the high risk factors that affect IFS prognosis.Methods:Totally, 16 patients were diagnosed IFS in Department of Pedia-trics, Beijing Tongren Hospital, Capital Medical University from October 2013 to December 2019.The clinical features and the high risk factors were analyzed by using SPSS 21.0 software.Results:(1)The median age at diagnosis was 0.13 years (0 to 4.92 years), predominantly in males(14/16 cases, 87.5%). (2)Focus site: 10 cases were located in the extremities, 3 cases in the head and neck, and 3 cases in the trunk.(3)Treatment plan was mainly surgical combined chemotherapy.The initial treatment was " Vincristine + Cyclophosphamide + Actinomycin D" . Among the 15 cases receiving chemotherapy, 3 cases were insensitive to chemotherapy and 12 cases were sensitive to chemotherapy.There were 14 cases of tumor resection and 2 cases of biopsy.(4) The median follow-up time was 3.5 years, and 3 patients′ parents gave up the treatment due to the progress of the disease after chemotherapy and died.The remaining 13 cases were completely relieved until the follow-up period, of which 2 cases relapsed (2/16 cases, 12.5%) and the overall 5-year survival rate was about 70%.Grouped by pathological grade, the total 5-year survival rate of children with G1 and G2 was 100%, and G3 was only 30%, with statistically significant differences ( χ2=4.853, P=0.028). Conclusions:The overall prognosis of IFS is favorable.Tumor grade and lesion size are important factors that affect the prognosis.Adjuvant chemotherapy is beneficial to complete tumor resection, and chemotherapy is recommended for children with high risk factors.
ABSTRACT
Objective:To explore the cellular protective effect and adverse reactions of amifostine in the chemotherapy of malignant solid tumor in children.Methods:A total of 62 children with malignant solid tumors receiving 253 times of chemotherapy who were admitted to the Pediatrics Single Center of Beijing Tongren Hospital from April 2018 to April 2020 were selected and divided into the experimental group (amifostine was used before chemotherapy, 113 times in total) and the control group (amifostine was not used before chemotherapy, 140 times in total) according to stratified random sampling. The self-control method was used to compare the therapeutic effects and adverse effects of the use of amifostine or not in the same child under the same chemotherapy regimen.Results:Compared with the control group, the duration of agranulocytosis [(6.7±3.0) d vs. (9.5±4.3) d, t = 3.788, P < 0.05], the duration of platelet reduction (<20×10 9/L) [(3.6±1.3) d vs. (5.4±3.2) d, t = 2.037, P < 0.05], the time of receiving recombinant human granulocyte colony-stimulating factor (rhG-CSF) treatment [(6.5±3.5) d vs. (10.0±2.8) d, t = 3.049, P < 0.05] and the time of antibiotic treatment during infection [(5.0±2.5) d vs. (8.2±2.5) d, t = 3.558, P < 0.05] in the experimental group were all shorter; the amount of platelet input required [(0.7±0.5) U vs. (1.5±0.8) U, t = 2.873, P < 0.05] was less than that of the control group. Oral mucosal ulceration occurred in only 4 (3.5%) times in the experimental group, which was lower than that in the control group [12 (8.6%) times] ( χ2 = 4.634, P = 0.033). Regardless of the cost of amifostine itself, there was a statistically significant difference in treatment cost between the experimental group and the control group ( P = 0.034), and the length of hospital stay in experimental group was relatively short ( P = 0.012). The patients were more prone to nausea and vomiting and hypocalcemia when treated with amifostine. Conclusions:Amifostine can effectively protect normal tissue cells in chemotherapy of children with malignant solid tumor and its adverse reactions are mild.
ABSTRACT
Objective:To study the technical and essential steps in laparoscopic selective devascularization with paraesophageal veins-preservation.Methods:To retrospectively analyze the clinical data of 13 cirrhotic patients who underwent laparoscopic selective pericardial devascularization for portal hypertension at the Department of Hepatobiliary and Pancreatic Surgery, Zhejiang Provincial People's Hospital from January 2019 to March 2020. There were 9 males and 4 females with age ranging from 41 to 83 years (median 51 years). The operative time, intraoperative blood loss, postoperative complications and follow-up data were analyzed.Results:All the 13 patients completed theoperation, no patient stopped the operation or transferred to laparotomy. The operation time was (170±32) min.The intraoperative bleeding was (160±30) ml. The postoperative hospital stay was (6.1±1.1) days. There were no complications, including pancreatic leakage and intra-abdominal infection. On follow-up which ranged from 1 to 15 months, one patient developed portal vein thrombosis, no upper gastrointestinal rebleeding.Conclusions:Preservation of esophageal veins in laparoscopic selective devascularization is an accurate surgery which requires close teamwork and rich experience in laparoscopic surgery. The preservation of the main trunk of the gastric coronary vein and integrity of the esophageal veins are the keys to the surgery which is safe and feasible.
ABSTRACT
Objective:To investigate the clinical features and adjuvant chemotherapy of children with medulloblastoma(MB).Methods:Clinical data of 21 pathologically confirmed MB children admitted to the department of pediatrics of Beijing Tongren Hospital affiliated to Capital Medical University from May 2012 to November 2017 were collected to analyze the clinical efficacy and prognosis of multidisciplinary combined treatment.Results:There were 21 children enrolled in the study(15 males and 6 females; median age: 6 years and 3 months). The majority of tumors were from the fourth ventricle(66.7%, 14/21 cases). The most common type of pathological tissue was classic medulloblastoma(61.9%, 13/21 cases). Most of the molecular types was type 4(47.6%, 10/21 cases). There were 15 cases(71.4%)in the high-risk group and the remaining 6 cases(28.6%)in the low-risk group without metastasis(M0 stage). Total tumor resection was performed in 16 cases(76.2%). The patients were followed up to December 2019(median follow-up time was 29 months). After comprehensive treatment, 11 patients died and 6 patients relapsed.The 2-year survival rate was 61.5%, and the 5-year survival rate was 51.1%.Cox regression multivariate analysis showed that the survival rate of children with no tumor spread, short time interval between radiotherapy and surgery was higher( P<0.05). Conclusion:The incidence of MB in boys is higher than that in girls.Whether the tumor is disseminated or not, the time interval between radiotherapy and surgery are independent risk factor affecting the prognosis.Multidisciplinary combination therapy can effectively improve the long-term prognosis.
ABSTRACT
Objective:To investigate the pathogen types and drug resistance of catheter-related bloodstream infection (CRBSI) in children with solid tumor after chemotherapy.Methods:The clinical characteristics, pathogenic bacteria composition and drug sensitivity test results of children hospitalized with chemotherapy and indwelling periphe-ral venous catheter (PICC) and central venous catheter (CVC) in the non-Intensive Care Unit (ICU) of the Pediatric Ward of Beijing Tongren Hospital, Capital Medical University from January 2014 to December 2015 were retrospectively summarized.Results:A total of 3 361 cases received chemotherapy, 3 300 cases received PICC and CVC, and the blood cultures of 64 cases were sent for test. Twenty-four cases had CRBSI, 4 of who were of fungal infection. The infection rate of CRBSI was 0.7% and the infection rate of fungi was 0.12%. A total of 14 pathogenic bacteria were isolated, including 3 strains of Gram-negative bacteria (21.4%), 9 strains of Gram-positive bacteria (64.3%), and 2 strains of fungi (14.3%). The main pathogenic bacteria detected positive in 24 cases (12 cases were drug-resistant) included the methicillin-resistant coagulase-negative staphylococci (3 cases), carbapenem-resistant Klebsiella pneumoniae (7 cases) and extended spectrum beta-lactamases(ESBLs)producing Escherichia coli (2 cases), and their detection rates were 12.5%, 29.2% and 8.3%, respectively.The sensitivity rate of coagulase-negative staphylococci to Vancomycin, Meropenem and Linezolid was 100%.Candida glabrata and candida 100% sensitive to Voriconazole, Amphotericin B and Flucytosine but not sensitive to Fluconazole and Itraconazole. Conclusions:Monitoring the occurrence and etiological changes of CRBSI in children with solid tumors is helpful to further strengthen effective prevention and control measures and provide early empirical antimicrobial therapy.
ABSTRACT
Objective:To investigate the clinical features, diagnosis, treatment and prognosis of advanced clear cell sarcoma of kidney(CCSK) in children.Methods:The clinical data of 10 children with advanced CCSK hospitalized in Department of Pediatrics of Beijing Tongren Hospital, Capital Medical University from January 2014 to December 2017 were collected, and their clinical features, diagnosis, treatment and prognosis were analyzed retrospectively.Results:(1) Clinical features of CCSK: ten cases of CCSK included 6 boys and 4 girls, with the median onset age of 32 months; 7 cases were left CCSK and 3 cases were right CCSK.There were 9 cases of stage Ⅲ and 1 case of stage Ⅳ at the time of initial diagnosis, when 4 cases were misdiagnosed as other renal tumors at the time of initial diagnosis(40%, 4/10 cases). Five patients with stage Ⅲ CCSK had recurrence and metastasis during treatment and follow-up, and the main distant metastasis sites were lung, bone, liver and brain.(2) Treatment and prognosis of CCSK: seven cases received surgery combined with radiotherapy and chemotherapy, and 3 cases whose parents gave up treatment adopted non-standardized treatment.The median follow-up time was 33.5 months.Seven patients survived and 3 cases died.The 3-year overall survival rate of all 10 patients was 65.6%.The 3-year overall survival rate of stage Ⅲ was 74.1%, and that of stage Ⅳ was 0.The prognosis of stage Ⅲ was significantly better than that of stage Ⅳ( χ2=9, P=0.003). Among the 5 recurrent cases, only 1 case achieved completely remission, 2 cases achieved partially remission, 1 case suffered from disease progression and 1 case died.The 3 cases without recurrence were given standardized treatment of surgery, che-motherapy and radiotherapy, and all were completely remitted. Conclusions:CCSK is easy to be misdiagnosed, and the risk of recurrence and distant metastasis is high in stage Ⅲ patients during treatment and follow-up.Stage Ⅲ patients who actively receive standard treatment including surgery, chemotherapy and radiotherapy have good prognosis, while the mortality of patients with relapse and distant metastasis is high.
ABSTRACT
Objective:To study the relationship between high-risk factors with the diagnosis, treatment and prognosis of children with high-risk head and neck rhabdomyosarcoma (RMS).Methods:Children with high-risk RMS primarily found in head and neck were selected as research objects according to the criteria of RMS risk degree formulated by Children Oncology Group (COG) and Children′s Rhabdomyosarcoma Cooperative Group, Children′s Hematological Oncology Group, China Anti-Cancer Association (CCCG-RMS), and combined treatment including puncture pathology/surgery, chemotherapy and radiotherapy were performed.The relationship with primary site, age, pathology type and metastasis and prognosis were analyzed.Results:Twenty-nine patients were collected as research object, 17 cases (58.6%) of male, and 12 cases (41.4%) of female.The primary site: orbit was 7 patients (24.1%), and para-meningeal was 22 patients (75.9%). Clinical stage: 2 cases were stage Ⅲ (6.9%), and 27 cases were stage Ⅳ (93.1%). Followed up to December 31, 2018, 14 patients were dead, 15 patients were survival, and 10 patients were event free survival.The overall survival rate was 48.3%(15/29 cases), and the event free survival rate was 34.5%(10/29 cases). According to Kaplan- Merier survival curve analysis, the average overall survival time was (76.0±12.0) months, 95% confidence interval (95% CI): (53.5-93.2)months.The event free survival time was (62.5±10.6) months, 95% CI: (47.0-83.9)months. Conclusions:The prognosis of high-risk head and neck RMS is poor.The center system metastasis is cause of death.Thus, the main task is how to close follow-up and prevention of central nervous system invasion for improving prognosis.
ABSTRACT
Objective:To summarize the prognostic characteristics of hepatoblastoma in children undergoing pulmonary metastasectomy.Methods:The clinical data of 48 hepatoblastoma patients with pulmonary metastases who underwent pulmonary metastases resection in our hospital from January 1 2009 to December 31, 2017 were collected, and prognosis of these patients was analyzed.Results:Forty eight cases were diagnosed as hepatoblastoma with pulmonary metastasis, including 30 cases with pulmonary metastasis alone and 18 cases accompany with other high risk factors affecting prognosis. All the 48 patients underwent pulmonary metastasectomy, in which 43 patients were given pulmonary metastases resection completely and 5 patients were given partial resection of metastases. Twenty-five cases recurred after the first pulmonary metastasis resection(25/48, 52.1%), and 2 cases progressed. With the median follow-up time of 45.5 months, survival time of 48 patients with pulmonary metastasectomy was(83.59±7.01)months, and the 3-year overall survival rate was 58%. Of the groups those were patients with pulmonary metastasis alone and patients with other high risk factors affecting prognosis, the survival time and the 3-year overall survival rate showed a significant statistical differences[(95.89±8.19)months vs.(58.95±9.40)months; 79.4% vs.50%; χ2=4.849, P= 0.028)]. The survival time and 3-year survival rate of the two groups between with recurrence or progression and the group without recurrence or progression after pulmonary metastases resection were showed a significant difference[(56.84±7.22)months vs.(112.48±7.08)months; 55.6% vs.90.5%; χ2=11.03, P= 0.001)]. Results of COX regression analysis showed that the main risk factor affecting prognosis was pulmonary metastasis accompany with other high-risk factors for hepatoblastoma patients. The death risk of patients with pulmonary metastasis accompany with other high-risk factors was 3.424 times than that of patients without other high-risk factors( RR=3.424, 95% CI: 1.264~9.275). Conclusion:The overall prognosis of patients with pulmonary metastases is not good, and the proportion of postoperative recurrence is very high. Pulmonary metastasis accompanied with other high risk factors is the main risk factor affecting the prognosis of patients with pulmonary metastasectomy.
ABSTRACT
Hepatoblastoma(HB)is the most common primary malignant liver tumor in children, 90% occurs within 5 years old.Its event-free survival rate within 3 years after comprehensive treatment can reach 60%~70%.As one of the clinical manifestations of high-risk HB, tumor thrombus of hepatic and endovascular system can existed in central veins, such as portal vein, vena cava and even atrium.HB often induces massive hemorrhage of upper digestive tract, refractory ascites, liver failure and other complications.It seriously affects prognosis.In recent years, surgery, comprehensive chemotherapy, interventional therapy, radiotherapy, radiofrequency ablation, targeted therapy and high intensity radiofrequency focused knife therapy have made progress.Tumor thrombus is still a common characteristic of refractory HB.In this review, we expound the clinical progress of pediatric HB with cancer thrombus in recent years in order to improve its treatment and prognosis.
ABSTRACT
Objective:To build a medical service experience system based on role play of hospital staff, and explore its contribution to upgrading medical service, elevating medical service quality, and improving patients′ satisfaction.Methods:An indicator system for medical service experience was developed via literature review. 20 newly recruited hospital employees in 2019 were sampled randomly to form a service experience team, who were arranged to experience the full medical service process of outpatients and inpatients based on role play. The questionnaire for service quality based on patient perception and expectation was used to survey the expectation and perception values of those role players on their medical service experiences, and summarize the defects found on such six dimensions as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness. After due corrections of these defects, further experiences and patient satisfaction survey were made to assess the effects of such actions taken. Paired t test was used respectively in statistical analysis of service experience value and actual perception value, as well as the perception values before and after the actions taken, and χ2 test was used for a statistical analysis of patient satisfaction. Results:Role players experienced respectively at the emergency, outpatient and inpatient departments of the hospital for a week in August 2019. Statistics of their experiences indicated≥0.50 points difference between the mean expectation and perception values on doctor-patient communication, patient help responsiveness, outpatient process, examination report delivery duration, service attitude, patient trust on medical workers, medical environment and patient privacy protection.Following a 3-month reform, role players found improvements in such aspects as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness; patient satisfaction improved sizably in December 2019 over January of the same year( P<0.05). Conclusions:The construction and application of the medical service experience system based on role play of hospital staff prove highly useful in upgrading medical service actions, improving medical service quality, and improving patient satisfaction.
ABSTRACT
Objective:To improve the clinicians′ understanding of central nervous system (CNS) metastasis in children with solid tumors.Methods:The clinical data of 33 cases of CNS metastasis among 611 children with malignant solid tumors in the chest and abdomen from September 2005 to December 2016 in Beijing Tongren Hospital, Capital Medical University were retrospectively analyzed. The clinical characteristics, treatment and prognosis of metastasis were statistically analyzed according to different pathological types of malignant solid tumors in children with CNS metastasis.Results:Among the 611 children with malignant solid tumors in the chest and abdomen, 15 patients were neuroblastoma with CNS metastasis (5.9%, 15/264), 13 patients were hepatoblastoma with CNS metastasis (4.8%, 13/274), two cases were Wilms tumor with CNS metastasis (3.2%, 2/63), and three cases were clear cell sarcoma of the kidney with CNS metastasis (3/10). The onset age of the malignant solid tumors was 3-189 months, and the median age of onset was 26.5 months. The time from the diagnosis of primary malignant solid tumor to diagnosis of CNS metastasis was 0-100 months, and the median time of metastasis was 18 months. The neuroimaging features of CNS metastasis were as follows:30 cases with brain metastasis, three cases with meningeal metastasis, and five cases with spinal cord involvement. Cerebrospinal fluid cytology was positive in two cases (2/3). Of the 33 patients with CNS metastasis, five underwent intracranial tumor resection combined with radiotherapy and chemotherapy, two underwent surgery alone, three underwent radiotherapy alone, and 23 underwent chemotherapy alone. After a median follow-up of 36 months, the survival time of 33 malignant solid tumors with CNS metastasis was (16.96±3.19) months, and the overall survival rate of three years was only 14.7%. The survival time of the patients with intracranial tumor surgery combined with radiotherapy and chemotherapy, surgery alone, radiotherapy alone, and chemotherapy alone was (40.50±4.32), (3.00±0), (35.50±5.50) and (10.35±2.84) months, respectively; and the three-year overall survival rates were 50.0%, 0, 50.0% and 4.3%, respectively (χ 2=15.19, P=0.002). The prognosis of the patients with intracranial tumor resection combined with radiotherapy and chemotherapy was the best. Conclusions:The highest incidence of CNS metastasis in children with malignant solid tumors in the chest and abdomen was found in the clear cell sarcoma of the kidney. The prognosis of CNS metastasis was found to be poor. But the comprehensive therapy of intracranial tumor resection combined with radiotherapy and chemotherapy can prolong survival and improve prognosis.
ABSTRACT
Hilar cholangiocarcinoma (HCCA) is a malignant tumor of the biliary tract with dismal prognosis. However the preoperative imaging has limited value to evaluate the clinical stage, and radical resection remains the only potential curative option for these patients. The application of laparoscopic technique in HCCA is still in the preliminary stage with very few reports due to controversies on its safety and oncological adequacy. In this paper, we summarized the current status of laparoscopic resection for hilar cholangiocarcinoma in order to provide theoretical basis for the decision-making in clinical practice.
ABSTRACT
Objective@#To study on the mRNA expression level of IN1 gene associated with the clinical efficacy and prognosis of hepatoblastoma(HB) in children and to elucidate the early warning value of IN1 gene for prognosis and chemotherapy sensitivity.@*Methods@#Forty HB patients were selected based on primary diagnosis and treated from January 2015 to May 2018 in Tongren Hospital Affiliated to Capital Medical University. The expression level of INI1 gene was detected by using fluorescence immuno-PCR. Clinical data of children with HB were collected, including staging, grouping, risk, efficacy and prognosis of chemotherapy. The relationship between the mRNA expression of IN1 gene and clinical data was analyzed by SPSS 21.0 software.@*Results@#(1)Clinical characters: the medium age of 40 HB patients was(30.50±2.39) months, male 29 cases (72.5%), and female 11 cases (27.5%). There was 1 case (2.5%) of stage Ⅱ HB, 13 cases (32.5%) of stage Ⅲ HB, and 26 cases (65.0%) of stage Ⅳ. The low-and intermediate- risk group had 12 cases (30.0%) of HB, and the high-risk group had 28 cases (70.0%) of HB.(2)Clinical efficacy and prognosis: by July 1st, 2018, the medium following-up time was (12.2±10.1) months, 4 patients (10%) were treated by chemotherapy without surgery, and 36 patients (90%) were treated by surgery .All patients (100%) received chemotherapy.The average cycle of chemotherapy lasted(13.17±0.02). Ten patients were dead and 30 patients survived till following-up.The overall survival (OS) rates were 75% and the event-free survival rates were 50% (20 patients with HB). (3) IN1 gene mRNA expression: The average PCR quantitative of IN1 gene mRNA of 40 HB patients(2-ΔCT)was 0.31±0.70.The average mRNA quantitative of HB patients (2-ΔCT)with high-risk and low/intermediate-risk group was 0.23±0.43 and 0.48±1.13(t=6.363, P=0.05). According to histology diagnosis, the average mRNA quantitative of small cell undifferentiated (SCU) type (12 cases)and other type (25 cases) was 0.09±0.11 and 0.43±0.86(t=4.533, P=0.04). The average mRNA quantitative of patients with or without radical surgery was 0.04±0.03 and 0.34±0.74 (t=2.935, P=0.022). The data of children with poor chemotherapy sensitivity(19 cases)and those sensitive to chemotherapy (21 cases) were 0.03±0.04 and 0.30±0.82, and the difference was statistically significant (t=5.688, P=0.018).@*Conclusions@#Poor therapeutic effect results in low mRNA expression of IN1 gene in children of HB.The IN1 gene expression could be an early warning factor for treatment sensitivity and prognosis.
ABSTRACT
Objective@#To investigate the expression of B7H3 in neuroblastoma (NB) tissues and its relationship between clinical characteristics and prognosis of patients.@*Methods@#The clinical data and pathological wax of 100 cases with neuroblastoma admitted from January 2000 to December 2015 in Sun Yet-Sen University Cancer Center were collected.The expression of B7H3 in tumor tissues was detected by immunohistochemistry (IHC) and then the expression of B7H3 and its relation to pathological parameters and survival rate of patients were analyzed.@*Results@#(1) The positive rates of B7H3 in tumor tissues were 79% (79/100 cases), of which 37 were weak positive, 31 were mode-rate positive, 11 were strong positive, 58%(58/100 cases) showed low expression and 42%(42/100 cases) showed high expression.(2)The positive rate of B7H3 was positively correlated with the risk stratification, age, stage, primary site and N-MYC gene status (r=0.621, 0.350, 0.730, 0.224, 0.335; all P<0.05). (3)The high expression rates of B7H3 were positively correlated with the risk, stage, N-MYC gene status and tumor size (r=0.177, 0.016, 0.175, 0.284; all P<0.05). (4)B7H3 negative and positive 4-year event free survival (EFS) rates of 100 patients were 89.5% and 19.9% (χ2=31.260, P<0.001), 4-year overall survival(OS) rates were 94.7% and 48.3% (χ2=20.212, P<0.001), for 33 non-high-risk patients, B7H3 negative and positive 4-year EFS rates were 100.0% and 47.3% (χ2=8.760, P=0.003), and 4-year OS rates were 100.0% and 93.8% (χ2=1.063, P=0.003), respectively.Sixty-seven high-risk patients with B7H3 negative and positive 4-year EFS were 50.0% and 15.4% (χ2=4.093, P=0.043), 4-year OS were 75.0% and 42.0%, respectively (χ2=1.872, P=0.171). (5)The 4-year EFS rates of 100 patients with B7H3 low expression and high expression were 41.8% and 27.1% (χ2=3.801, P=0.051), and 4-year OS rates were 58.6% and 63.8% (χ2=0.111, P=0.739), respectively.The 4-year EFS and OS rates for 33 non-high-risk patients with B7H3 low expression and high expression were 94.7% and 44.2% (χ2=9.122, P=0.003), 100.0% and 90.9% (χ2=2.000, P=0.157), respectively.The 4-year EFS and OS rates of 67 high-risk patients with high expression and low expression of B7H3 were 13.9% and 22.1% (χ2=0.061, P=0.805), 36.3% and 57.7%(χ2=2.060, P=0.151), respectively.(6)Multivariate analysis showed that OS and EFS in B7H3 positive patients were lower than those in B7H3 negative patients[RR 95%CI: 28.110 (2.430-325.148); P=0.008; RR 95%CI: 12.834 (2.669-61.715), P=0.001].@*Conclusions@#The positive rate of B7H3 in neuroblastoma is high, and the expression level of B7H3 is closely related to the clinical characteristics of the patients.Positive B7H3 in tumor tissues is an independent poor prognostic factor.B7H3 may be one of the new prognostic indicators for NB.
