Objective To investigate the risk factors for postoperative recurrence and metastasis in patients with T1 stageⅢ/Ⅳ clear cell renal cell carcinoma(ccRCC), and to analyze the influence of surgical methods on prognosis, so as to provide prognostic evaluation and treatment guidance for clinical practice. Methods A retrospective analysis was conducted on 398 patients diagnosed with T1 stage Ⅲ/Ⅳ ccRCC who underwent either partial nephrectomy(PN)or radical nephrectomy(RN)at Jiangsu Province Hospital during Jan. 2008 and Sep. 2022. The patients were divided into recurrence group(n=49)and non-recurrence group(n=349)according to whether the tumor recurred during the follow-up period. The general, clinical data and prognosis were compared between the two groups. Univariate and multivariate Cox regression analyses were used to explore the factors influencing disease-free survival(DFS)and overall survival(OS)after surgery. Subgroup analysis using Kaplan-Meier curves was performed for T1a and T1b patients. Results During the median follow-up of 67(42, 98)months, the recurrence group was characterized by older age, larger tumor diameter, higher proportion of T1b stage, and more complex tumor anatomy. Univariate and multivariate Cox regression analyses showed that age ≥55 years and R.E.N.A.L. score ≥7 were independent risk factors for poorer DFS and OS(P＜0.05). Subgroup analysis revealed that PN or RN did not significantly affect DFS or OS in T1a patients and OS in T1b patients, while RN significantly improved DFS in T1b patients(P＜0.05). Conclusion Age ≥55 years and R.E.N.A.L. score ≥7 are independent risk factors for poor DFS and OS in highgrade T1 ccRCC patients. For T1b patients, RN may improve DFS.

Objective:To analyze the clinical features, imaging features and diagnosis and treatment process of a female pelvic epithelioid inflammatory myofibroblastic sarcoma (EIMS) with peritoneal metastasis, so as to improve the clinical understanding and diagnostic ability of the disease and avoid misdiagnosis and missed diagnosis.Methods:The clinical data of a female patient with pelvic EIMS combined with peritoneal metastasis in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed.Results:The triad examination of the patient involved an irregular solid mass in the pelvic cavity about 8.0 cm×9.0 cm in size. Laboratory examination revealed human epididymal protein 4(HE4)154.00 pmol/L. The ultrasonography showed multiple low-echo masses in deep pelvic cavity with unclear boundary and uneven internal echo, and color doppler flow imaging (CDFI) showed abundant internal blood flow signals. Enhanced CT showed uneven and obvious enhancement of the lesion. Pathological examination showed the infiltration of inflammatory cells in the mucous interstitial background. The tumor cells were round and epithelioid, with large nuclei, deep staining and obvious nucleolus. Immunohistochemistry showed anaplastic lymphoma kinase (ALK) positive, and molecular pathology fluorescence in situ hybridization showed ALK gene amplification (positive). Combined with pathological, immunohistochemical and genetic tests, EIMS was diagnosed. Conclusions:EIMS should be considered when there are single or multiple solid or cystic nodules or masses in the pelvic cavity with obvious enhancement, invasive growth and peritoneal implantation metastasis, and the correct diagnosis can be made according to the pathological findings, immunohistochemistry and genetic test results.

Objective To investigate the influencing factors of ERCP stent implantation for patients with malignant obstructive jaundice.Methods 130 patients with malignant obstructive jaundice who received ERCP stent implantation in our hospital from January 2017 to January 2024 were retrospectively included,and grouped according to the jaundice control effect 4 weeks after surgery.Univariate and multivariate analysis of the efficacy of ERCP stent placement in malignant obstructive jaundice after 4 weeks.Construction of a predictive model for the efficacy of ERCP stent placement in malignant obstructive jaundice after 4 weeks and clinical efficacy analysis.Results There were 64 cases for jaundice resolved in 4 weeks after surgery among all 130 patients with the regression rate for 49.23％.The results of univariate analysis showed that the type of biliary obstruction,stent type,and preoperative Child Pugh grading may all be related to the efficacy of ERCP stent placement in malignant obstructive jaundice after 4 weeks(P＜0.05).The results of Logistic multivariate analysis showed that the type of biliary obstruction,stent type,and preoperative Child Pugh grade were all independent influencing factors on the efficacy of ERCP stent placement for malignant obstructive jaundice at 4 weeks(P＜0.05).Using the independent influencing factors and P-value prediction probability of Logistic regression model to predict the prognosis of patients,the ROC curve was used,with areas under the curve of 0.713,0.823,0.907,and 0.971,respectively.Conclusion The clinical effects of ERCP stent implantation in malignant obstructive jaundice was closely related to the type of biliary obstruction,stent type and preoperative Child-Pugh grade.The data model constructed using the above three factors has shown good performance in predicting the prognosis of patients.

Objective:To investigate clinical characteristics and genetic variations in a case of self-improving collodion ichthyosis in the adult stage.Methods:An adult patient with clinically suspected self-improving collodion ichthyosis was collected from the Department of Dermatology, Henan Provincial People′s Hospital in April 2023. Clinical data were collected from the patient and her parents. Peripheral blood samples were obtained from them, and whole blood DNA was extracted. Whole-exome sequencing was performed to screen genetic variation sites, which were then verified by Sanger sequencing. The deleteriousness of the identified variants was assessed using pathogenicity analysis software.Results:The 54-year-old female patient presented with facial and neck flushing, mild dry skin on the trunk and limbs, sheepskin-like skin of the dorsal hand, and short fingers. Genetic testing identified two in-frame deletion mutations c.406_408del (p.E136del) and c.769_801del (p.H257_Q267del) in the non-repetitive region of the ALOX12B gene in the patient, which were inherited from her father and mother respectively. Bioinformatics analysis revealed that both genetic variations were deleterious pathogenic mutations.Conclusions:Two in-frame deletion mutations c.406_408del (p.E136del) and c.769_801del (p.H257_Q267del) were identified in the non-repetitive region of the ALOX12B gene in the patient with self-improving collodion ichthyosis, which may contribute to the clinical phenotype of the patient. The mutation c.769_801del had not been reported in literature.

Objective:To explore the clinical significance of skeletonized lymph node dissection of No.12 lymph nodes after neoadjuvant therapy in patients with advanced gastric cancer.Methods:For this retrospective case-cohort study we collected data from patients with advanced gastric cancer who underwent neoadjuvant chemotherapy and D2 or more extensive curative resection including No.12 lymph node dissection at the First Affiliated Hospital of Sun Yat-sen University from January, 2011 to December, 2022. Patients were divided into two groups based on whether they received skeletonized dissection of No.12 lymph nodes: 177 cases were in the skeletonized group, and 55 cases were in the nonskeletonized group. The differences of prognosis between the two groups were compared, and logistic regression models were used to analyze the factors affecting No.12 lymph node metastasis in the overall cohort and No.12b or No.12p lymph node metastasis in the skeletonized group.Results:A total of 232 patients were included, with 84 females (36.2%) and 148 males (63.8%), with an average age of 56.4±11.6 years. The proportion of female and ycT4 patients was significantly higher in the skeletonized group than in the nonskeletonized group (both P<0.05). Among all 232 patients, No. 12a metastasis occurred in 14 cases (6.0%). In the skeletonized group of 177 patients, No. 12b and No. 12p metastases were observed in 6 patients each (3.4%), and 4 patients had concurrent metastases in both No. 12b and No. 12a. The 5-year overall survival (OS) rates were 45.5% in the skeletonized group and 42.8% in the nonskeletonized group, with no statistical difference (HR=0.755, 95%CI: 0.488-1.168, P=0.580). The 5-year disease-free survival (DFS) rates were 39.8% and 41.0%, respectively, also with no statistical difference (HR=0.775, 95%CI: 0.513-1.172, P=0.584). 5-year OS for patients without No.12 lymph node metastasis was 48.8%, which was higher than the 15.9% for those with metastasis (HR=0.349, 95% CI: 0.209-0.584, P=0.003). Additionally, the 5-year DFS for those without metastasis was 44.3%, significantly higher than the 5.7% for those with metastasis (HR=0.444, 95%CI: 0.276-0.716, P<0.001). For patients without No. 12b or No. 12p lymph node metastasis, the 5-year OS was 47.6%, and the 5-year DFS was 42.3%, both of which were significantly higher than the 16.7% and 8.3% for those with No.12b or No. 12p lymph node metastasis, respectively (HR=0.353, 95%CI: 0.183-0.681, P=0.005; HR=0.457, 95%CI: 0.244-0.855, P=0.006). Multivariate analysis showed that more advanced ypN stage (OR=3.908, 95%CI:1.638-9.323, P=0.002) and tumor location in the lower stomach or whole stomach (OR=3.533, 95%CI: 1.312-9.511, P=0.012) were independent risk factors for No.12 lymph node metastasis and also for No.12b and No.12p lymph node metastasis (OR=2.426, 95%CI: 1.212-4.856, P=0.012 and OR=4.908, 95%CI:1.182-20.373, P=0.028, respectively). Conclusion:Patients with advanced gastric cancer who have more advanced ypN stage and tumor location in the lower stomach or whole stomach have a higher risk of No.12b and No.12p metastasis and thus require further skeletonized lymph node dissection of No.12.
