Uveal melanoma(UM)is the most common primary intraocular malignancy in adults, characterized by high invasiveness and unique metastatic biological features. Although local treatments(such as proton beam therapy and brachytherapy)can effectively control the primary lesion, approximately 50% of patients eventually develop distant metastasis, with the liver being the primary target organ(occurring in 90% of cases). This highlights a paradigm shift in treatment focus from mere local control to systemic prevention and management. For metastatic UM(mUM), current treatment strategies encompass biomarker-guided molecular targeted therapy, immunotherapy(including Tebentafusp, vaccines, and oncolytic virus therapy), and liver-directed therapy. Focusing on the synergy between local and systemic prevention and control, this article systematically elaborates on the precision local treatment for primary UM, the decision-making pathway for systemic treatment of metastatic UM based on molecular subtyping, the integration of local and systemic therapies for liver metastases, and the translational value of nanomedicine in addressing therapeutic bottlenecks. It provides insights for optimizing clinical management of mUM and developing novel therapeutic strategies.

Objective:To investigate the key genetic mutations during the progressive disease (PD) /leukemic transformation (LT) course in MDS by analyzing the dynamic changes of genetic mutations in patients with myelodysplastic neoplasms (MDS) with or without PD/LT.Methods:This study enrolled 84 patients with sequential MDS from May 2019 to August 2023 at ZhongDa Hospital Southeast University and used the next generation sequencing to detect gene mutations. The dynamic changes of genetic mutations in patients with MDS with or without PD/LT were retrospectively analyzed.Results:①This study analyzed data from 84 patients diagnosed with MDS with a median age of 63 (range: 31-95) years and consisting of 51 males and 33 females. Participants were distributed to the PD cohort ( n=20), LT cohort ( n=13), and non-PD/LT cohort ( n=51). Patients from the PD/LT cohorts demonstrated a higher proportion of bone marrow blasts than the non-PD/LT cohort at the first sequencing (1.6% vs. 0.4%, P=0.013). ②The most frequently mutated genes that were detected at first sequencing were ASXL1 ( n=21, 25.0%), TP53 ( n=17, 20.2%), TET2 ( n=12, 14.3%), DNMT3A ( n=11, 13.1%), and U2AF1 ( n=11, 13.1%). Further, patients from the PD/LT cohorts exhibited a higher median number of mutated genes than the non-PD/LT cohort (2 vs.1, P=0.014) at first sequencing. TET2 (27.3% vs. 5.9%, P=0.010), SETBP1 (15.2% vs.2.0%, P=0.033), and RUNX1 (18.2% vs. 2.0%, P=0.013) mutations were enriched in the PD/LT cohorts than in the non-PD/LT cohort. ③The most frequently detected acquired mutations (Ⅰ mutations) and clonally expanded mutations (Ⅱ mutations) were TP53 ( n=9, 10.7%), TET2 ( n=7, 8.3%), ASXL1 ( n=7, 8.3%), and RAS pathway ( n=7, 8.3%). Furthermore, patients from the PD/LT cohorts showed a higher median number of Ⅰ/Ⅱ genes than the non-PD/LT cohort (2 vs. 0, P<0.001), and Ⅰ/Ⅱ RAS pathway (21.2% vs. 0, P=0.001), TP53 (27.3% vs. 0, P<0.001), and TET2 (18.2% vs. 2.0%, P=0.013) mutations were enriched in PD/LT cohorts than in the non-PD/LT cohorts. ④Most of the TP53 mutations (9/12, 75.0%) in PD/LT cohorts were Ⅰ/Ⅱ mutations, whereas all of the TP53 mutations in non-PD/LT cohort were clone-decrease mutations (Ⅲ mutations) (5/8, 62.5%) or clone-stable mutations (Ⅳ mutations) (3/8, 37.5%). Most of the RAS pathway mutations (7/8,87.5%) in the PD/LT cohorts were Ⅰ/Ⅱ mutations, whereas only one patient in the non-PD/LT cohort demonstrated RAS pathway mutations, which belonged to Ⅳ mutations. Conclusion:Patients from the PD/LT cohorts demonstrated a higher proportion of bone marrow blasts and a higher median number of mutations than the non-PD/LT cohort at first sequencing; TET2, SETBP1, and RUNX1 mutations were enriched in the PD/LT cohorts than in the non-PD/LT cohort at first sequencing. Patients from the PD/LT cohorts exhibited a higher number of Ⅰ/Ⅱ mutations than the non-PD/LT cohort. Further, Ⅰ/Ⅱ TP53, RAS pathway, and TET2 mutations were enriched in the PD/LT cohorts, and Ⅰ/Ⅱ TP53 and RAS pathway mutations may contribute to the PD/LT.

Objective:To analyze the short-term efficacy and safety of robot-assisted laparoscopic partial nephrectomy(RAPN)for non-metastatic pathological stage T 3a renal cell carcinoma. Methods:The clinical and pathological data of 45 patients with pathologically confirmed non-metastatic T 3a renal cell carcinoma who underwent RAPN at Sun Yat-sen University Cancer Center between January 2016 and December 2023 were retrospectively reviewed. There were 30 males and 15 females. The average age of the cohort was(54.3±10.7)years,and the average clinical tumor diameter was(4.9±1.8)cm. Of all the patients,35(77.8%)were asymptomatic,7(15.6%)presented with hematuria,and 3(6.7%)presented with lumbar pain. Preoperative imaging assessed 34 patients(75.6%)as having clinical stage T 3a,all suspected of involving the collecting system or perirenal fat invasion;the remaining 11 patients(24.4%)were assessed as having stage T 1-2 disease. The median R.E.N.A.L. nephrectomy score was 8.0(7.0,10.0). A history of hypertension,diabetes,or chronic kidney disease was present in 18 patients(40.0%). The primary endpoint was progression-free survival,and the secondary endpoints included postoperative complications and short-term renal function outcomes. Survival curve was estimated using the Kaplan-Meier method,and renal function comparisons were made using the paired t-test. Results:The RAPN was performed through a transabdominal approach in 32 patients(71.1%),with a median estimated blood loss of 150.0(50.0,300.0)ml. Seven(15.6%)patients required intraoperative blood transfusion. The median length of postoperative hospital stay was 4.0(4.0,6.0)days. Postoperative complications occurred in 6 patients(13.3%),including 5(11.1%)with mild complications and 1(2.2%)with a severe complication. Renal function returned to baseline in 24 of 39 evaluable patients(61.5%),while 3 patients(7.7%)developed surgery-related chronic kidney disease 3 to 12 months postoperatively,but none required dialysis. The median follow-up time was 31.8(22.7,50.9)months,12(26.7%)patients received programmed cell death protein 1 inhibitor adjuvant therapy postoperatively. During follow-up,3 patients experienced tumor recurrence,the 3-year progression-free survival rate of the entire cohort was 95.4%.Conclusions:For some carefully selected patients with T 3a renal cell carcinoma,RAPN performed by experienced surgeons is a feasible and safe option,providing excellent short-term oncological outcomes,complication control,and renal function recovery. The long-term efficacy remains to be seen.

Objective:To evaluate the changes in left ventricular structure and function in pregnant women with different severities of hypertensive disorders of pregnancy(HDP)using conventional echocardiographic parameters,strain,and tissue-tracking mitral annulus displacement(TMAD)parameters,and to validate and compare the application value of strain and TMAD parameters.Methods:A total of 148 singleton pregnant women with HDP and 100 healthy pregnant women(HP group)who attended the Third Affiliated Hospital of Zhengzhou University from October 2023 to July 2024 were selected. Conventional echocardiographic parameters,strain,and TMAD parameters were collected. Based on the severity of the disease,HDP patients were divided into the gestational hypertension group(GH group, n=49),non-severe preeclampsia group(NSPE group, n=35),and severe preeclampsia group(SPE group, n=64). The differences in various parameters between the HP,GH,NSPE,and SPE groups were compared. The correlation between the displacement ratio of the midpoint of the mitral valve annulus in the apical 4-chamber(AP4 Midpt%),the displacement ratio of the midpoint of the mitral valve annulus in the apical 2-chamber(AP2 Midpt%)and left ventricular global longitudinal strain(LVGLS)were analyzed,and ROC curves were plotted to analyze and compare the diagnostic efficacies of LVGLS,AP4 Midpt% and AP2 Midpt% for left ventricular function changes in HDP pregnant women. Results:① The analysis revealed no statistically significant differences in maternal age and height between the HP group and the HDP subgroups(all P>0.05). In contrast,statistically significant differences were observed in gestational age,systolic blood pressure,diastolic blood pressure,body mass index,and body surface area(all P<0.05). Additionally,significant differences were noted in left ventricular mass,left ventricular interventricular septum thickness at end-diastole,left ventricular posterior wall thickness at end-diastole,left ventricular end-diastolic dimension,left ventricular end-systolic dimension,left ventricular end-diastolic volume,left ventricular end-systolic volume,and stroke volume between the HP group and the HDP subgroups(all P<0.05),while the difference in left ventricular ejection fraction was not statistically significant( P>0.05). ② Significant differences were identified in strain and TMAD parameters between the HP group and the HDP subgroups(all P<0.05),with LVGLS,AP4 Midpt% and AP2 Midpt% exhibited the largest effect sizes( η p2=0.457,0.453,0.351). A progressive decline in strain and TMAD parameters was observed as the severity of HDP increased. ③ There were strong positive correlations between AP4 Midpt%,AP2 Midpt% and LVGLS( r=0.752,0.747;all P<0.001). ④ LVGLS,AP4 Midpt% and AP2 Midpt% all demonstrated significant diagnostic efficacies for changes in left ventricular function in HDP(AUC=0.840,0.847,0.791),and the differences in AUC among the 3 curves were not statistically significant(all P>0.05).⑤ The success rate of collecting TMAD parameters was significantly higher than that of strain parameters(99.24% vs. 93.58%, P<0.001). Conclusions:As the severity of the disease worsens,the changes of left ventricular structure and function in pregnant women with HDP become more and more significant. Both strain and TMAD parameters can early and sensitively identify the subclinical damage of left ventricular systolic function in HDP pregnant women,and both of them have the same diagnostic value. TMAD parameters can be used as a reliable substitute parameter of LVGLS in HDP pregnant women.
