Objective:To analyze and summarize the oncological outcomes after laparoscopic radical trachelectomy (LRT) for early stage cervical cancer.Methods:The clinical data and follow-up results of 148 patients with early stage cervical cancer who underwent LRT in Renji Hospital, School of Medicine, Shanghai Jiao Tong University from July 2014 to June 2023 were collected, while tumor outcomes and postoperative pregnancy were analyzed retrospectively.Results:(1) General situation: the median age of 148 patients with LRT was 33 years (range: 19-42 years). Pathological type: 111 cases of squamous cell carcinoma, 36 cases of adenocarcinoma, 1 case of adenosquamous carcinoma. International Federation of Gynecology and Obstetrics (2018) stage: 17 cases of stage Ⅰa1 with lympho-vascular space invasion, 25 cases of stage Ⅰa2, 102 cases of stage Ⅰb1, and 4 cases of stage Ⅰb2. (2) Tumor outcomes: 148 patients were followed up regularly after LRT, and the median follow-up time was 59 months (range: 2-104 months). During the follow-up period, 5 cases of tumor recurred (including 1 death), and the median recurrence time was 10 months (range: 4-33 months). Among them, there were 3 cases of pelvic metastasis, 1 case of distant metastasis, and 1 case of both pelvic and distant metastasis. Both 3-year and 5-year disease-free survival rates of 148 patients were 94.5%, and the 5-year overall survival rate was 98.9%. (3) Postoperative pregnancy: among 148 patients with LRT, 67 patients had pregnancy requirements, followed up for 1 year, and 20 of them were pregnant, with a pregnancy rate of 29.9% (20/67). Among the 20 pregnant patients, 2 cases early abortion, 1 case mid-term abortion, and 17 cases gave birth (including 4 cases of premature birth and 13 cases of full-term birth).Conclusion:Under the condition of strict control of surgical indications, guaranteed surgical scope and tumor-free operation, LRT in patients with early cervical cancer has a good outcome.

Objective:To evaluate the efficacy and safety of comprehensive treatment for retinoblastoma (RB).Methods:A retrospective clinical study. From January to December in 2019, 157 cases (203 eyes) of RB who were diagnosed by the Department of Ophthalmology of Xinhua Hospital and received comprehensive treatment were included in this study. Of cases, 76 were male, and 81 were female; 111 were unilateral, and 46 were bilateral. The medium of age at diagnosis was 20.1 months. All patients received treatment for the first time. Patients with intraocular tumors were divided into A-E stages, extraocular stage and distant metastasis according to international intraocular RB classification standard. The median follow-up time was 37.4 months. Clinical features, treatment, prognosis and ocular complications of all cases were recorded.Results:Among 157 cases (203 eyes), 137 cases (180 eyes) were in intraocular stage; 6, 14, 10, 98, and 52 of eyes were in A-E stages, respectively. Twelve cases (12 eyes) were in extraocular stage; 8 cases (11 eyes) were in distant metastasis stag; 8 cases died due to distant metastasis; 149 cases (94.9%, 149/157) survived; 48 eyes were enucleated, 34 of which underwent initial enucleation, and 14 eyes underwent enucleation after eye-preserving treatment. The overall global salvage rate was 155 eyes (76.4%,155/203), and that after eye-preserving treatment was 91.7% (155/169). Severer eye for bilateral cases was taken into account for statistic; 120 cases (120 eyes) received initial eye-preserving treatment. Among them, 36 and 84 eyes underwent initial intravenous chemotherapy (IVC) and initial intra-arterial chemotherapy (IAC), respectively. The enucleation of the two groups was 7(19.4%, 7/36), 7(8.3%, 7/84); 33 (91.7%, 33/36) and 33 (39.3%, 33/84) eyes received the second treatment, respectively. There was no significant difference in the rate of enucleation between the two treatments ( χ2=2.037, P=0.154). There was significant difference in the percentage of secondary treatment ( χ2=27.937, P<0.001). Fifty-four eyes (45.0%, 54/120) stabilized after initial treatment, and 66 eyes (55.0%, 66/120) underwent secondary treatments due to poor response or tumor recurrence. For 66 eyes receiving secondary treatments, enucleation, IAC, intravitreous chemotherapy (IVitC), IAC combined with IVitC, and laser and/or cryotherapy was performed in 6, 18, 12, 13, and 17 eyes, respectively. The number of eyes of enucleation among the IAC, IVitC, and IAC combined with IVitC group was 5 (27.8%, 5/18), 1 (9.3%, 1/12), and 2 (15.4%, 2/13) eyes, which was no significantly different ( χ2=2.001, P=0.368). Until the last follow-up, visual acuity outcomes were acquired in 148 eyes (72.9%, 148/203). Among them, 41, 53, 16 and 38 eyes had no light perception, light perception to finger counting, 20/400, and ≥20/200, respectively. In total, among 203 eyes, 121 eyes received IAC, of which 2, 4, and 1 eyes had optic disc atrophy, vitreous hemorrhage, and severe retinal-choroidal atrophy, respectively; 60 eyes received IVitC, of which one and one eye had vitreous hemorrhage and macular hemorrhagic necrosis, respectively. Conclusions:In this study, the overall survival rate was 94.9% after comprehensive treatment and the rate of global salvage after eye-preserving treatment was 91.7%. The comprehensive treatment of retinoblastoma had a relatively high efficacy and safety.

Objective:To evaluate the functional and anatomical outcomes of autologous single retinal pigment epithelium (RPE) transplantation for severe obsolete submacular hemorrhage (SMH) in late age-related macular degeneration (AMD).Methods:A retrospective clinical study. From January 2012 to December 2015, 11 patients with AMD (11 eyes) with obsolete SMH who were diagnosed and treated by pars plana vitrectomy (PPV) combined with autologous RPE transplantation at the Department of Ophthalmology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were included. Among them, there were 9 eyes in 9 males and 2 eyes in 2 females. All the eyes underwent the examinations of best corrected visual acuity (BCVA) and optical coherence tomography; 4 eyes underwent macular fixation function (MAIA) at the same time. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. All eyes were treated with PPV combined with autologous single-layer RPE transplantation or autologous RPE-choroidal full-thickness transplantation, and were divided into S group and C group, with 5 and 6 eyes respectively. The differences of age ( t=-0.363), gender composition ratio ( χ2=0.549), course and thickness of SMH ( t=0.118, 0.231), average times of anti-vascular endothelial growth factor drug treatments ( t=0.129), times of PPV ( t=-0.452) between the two groups were not statistically significant ( P>0.05). The follow-up period was 6-40 months after the operation, and the BCVA, MAIA, graft status and complications of the eyes after the operation were observed. The comparison of continuous variables between groups was performed by independent-sample t test; the comparison of categorical variables was performed by χ2 test. Results:At the last follow-up, the average logMAR BCVA of the eyes in group S and C were 1.62±0.34 and 1.03±0.20, respectively; group C was better than group S, however, the difference was not statistically significant ( t=1.532, P=0.160). There were 4 eyes (80%, 4/5) and 6 eyes (100%, 6/6) in S group and C group with BCVA better than preoperative, the difference was no statistical significance ( χ2=0.677, P=0.895). There were 2 (40%, 2/5) and 3 (50%, 3/6) eyes with logMAR BCVA better than 1.0 in S group and C group, and the difference was not statistically significant ( χ2=0.572, P=0.423). After the operation, 6 eyes of grafts were in good condition and 5 eyes were in poor condition; the BCVA of grafts in good condition was significantly higher than that of poor condition, the difference was statistically significant ( t=4.894, P=0.001). Among the 4 eyes that underwent MAIA examination, 2 eyes were unstable and diffusely fixed on the graft; the fixation point was located at the normal retina adjacent to the graft area in 2 eyes. Secondary subretinal hemorrhage occurred in 3 eyes after the operation; the intraocular pressure was high in 1 eye after the operation. During the follow-up period, no intraocular infection, secondary retinal detachment, recurrent choroidal neovascularization or low intraocular pressure occurred in all eyes. Conclusions:Both autologous single-layer RPE transplantation and autologous RPE-choroidal full-thickness transplantation can help stabilize or even improve the visual function of eyes with severe SMH secondary to advanced AMD. The visual acuity after surgery is closely related to the state of the graft.

Objective:To investigate the value of positron emission tomography/computed tomography (PET/CT) in diagnosis of retroperitoneal lymph node metastasis for early cervical cancer.Methods:Retrospectively analyze the preoperative PET/CT examination results and postoperative pathological results of patients with early cervical cancer who underwent surgical treatment from May 5, 2019 to August 31, 2020, and analyze the clinical characteristics, so as to explore the high risk factors of PET/CT in the diagnosis of retroperitoneal lymph node metastasis.Results:The accuracy, sensitivity, specificity and area under the curve (AUC) of PET/CT in the diagnosis of retroperitoneal lymph node metastasis were 75.2%, 60.0%, 81.3% and 0.707, respectively. Univariate analysis showed that 2009 International Federation of Gynecology and Obstetrics (FIGO) stage, tumor diameter >4 cm, lymphovascular space involvement (LVSI) positive, depth of invasion, high squamous cell carcinoma antigen (SCC-Ag) level and cytological grade were important factors for PET/CT in the diagnosis of retroperitoneal lymph node metastasis ( P<0.05); Multivariate analysis showed that tumor diameter >4 cm was an independent risk factor for PET/CT diagnosis of retroperitoneal lymph node metastasis ( P=0.015). Conclusions:PET/CT has a certain diagnostic value in the evaluation of retroperitoneal lymph node metastasis, but it can not fully reflect the facticity of lymph node metastasis; tumor diameter > 4cm is an independent risk factor for PET/CT in the diagnosis of retroperitoneal lymph node metastasis.

Objective:To observe and analyze the genotype and clinical phenotype in 34 families of familial exudative vitreoretinopathy associated with (FEVR) gene variation.Methods:Cohort study. Thirty-four FEVR families, in which the patients and both of their parents were all found to have FEVR-related gene mutations (proband 34 cases, 67 eyes; parents 68 cases, 136 eyes), were included in the study. These patients were identifIed from 722 FEVR patients through genetic screening, which diagnosed in Department of Ophtalmology of Xinhua Hospital and Tianjin Medical University Eye Hospital from January 2010 to December 2018. The probands and their parents underwent a comprehensive ophthalmological examination appropriate to their age, including BCVA, intraocular pressure, axial length, slit lamp examination, indirect ophthalmoscopy, FFA or color fundus photography or wide field color fundus photography. According to the severity of the disease, the clinical manifestations were divided into severe phenotype and mild phenotype. Thirty-four normal healthy people over 40 years old were included as the control group. The peripheral blood samples of FEVR family members and control group members were collected, and the genes known to be involved in FEVR, such as FZD4, LRP5, NDP, TSPAN12, ZNF408 and KIF11, were analyzed by next generation sequencing molecular genetics. The data were statistically analyzed by SPSS. The counting data was expressed in numbers or rates, and tested by Kruskal-Wallis test and χ2 test to find out the existence of significant difference. Results:In 67 eyes of the 34 probands, 48 eyes (71.64%) were classified into severe phenotype and 19 eyes (28.36%) were mild phenotype. In 136 eyes of 68 parents of the proband patients, 76 eyes (55.88%) were normal, 60 eyes (44.12%) were classified into mild phenotype, and no severe phenotype was found. A total of 65 variants of FEVR-related genes were detected in the 34 probands, of which LRP5 mutation was the most common (64.61 %), followed by FZD4 (12.31%), NDP (10.77%), TSPAN12 (6.15%), ZNF408 (4.62%) and KIF11 (1.54%). Missense mutations were the most common variant in FEVR-related genes. However, the results of correlation analysis indicated that there was no significant correlation between the type of mutation and the severity of clinical phenotype ( H=1.775, P=0.620). Among the 65 mutation types, 21 types have been previously identified and 44 were novel in this study. Thirty-nine eyes of 20 cases had only one single pathogenic mutation gene but with multiple mutation sites, 26 eyes of 13 cases carried 2 relevant pathogenic mutation genes, and 2 eyes in one case had 3 pathogenic mutation genes. The mutation frequencies of LRP5, NDP, ZNF408, FZD4, TSPAN12 and KIF11 genes in probands were significantly higher than those in control group, and the difference was statistically significant. The total mutation frequencies of LRP5, NDP, ZNF408, FZD4, TSPAN12 and KIF11 genes in proband group were significantly higher than those in control group ( χ2=64.702, P <0.001). Conclusions:In the FEVR families, the most frequent mutations were those in LRP5, followed by FZD4, NDP, TSPAN12,ZNF408 and KIF11. Missense mutation is the most common type of FEVR-related gene mutation, but there is no significant correlation between the clinical phenotype and gene variation type. Most of the probands were with severe clinical phenotype, while most of the parents with FEVR pathogenic gene mutation showed normal or mild manifestations.

Objective To observe the clinical characteristics of rhegmatogenous retinal detachment (RRD) secondary to conservative therapy in retinoblastoma (RB) patients.Methods A retrospective study. From July 2013 to May 2017, 20 RRD patients (20 eyes) of 456 RB patients (573 eyes) treated in Xinhua Hospital of Shanghai Jiao Tong University School of Medicine were included in the study. Eleven patients (11 eyes) were boy and 9 patients (9 eyes) were girls. Thirteen patients demonstrated bilateral RB and 7 patients had unilateral RB. Average age when diagnosed with RB was 25 months. International Classification of Retinoblastoma groups were C in 1 eye, D in 17 eyes, and E in 2 eyes. These patients received intra-arterial chemotherapy (17 eyes), intravenous chemotherapy (11 eyes), intravitreal chemotherapy (8 eyes), laser (14 eyes) and/or cryotherapy (5 eyes). Twelve patients (12 eyes) received vitreoretinal surgery including vitrectomy (6 eyes) and scleral buckling (7 eyes). The mean follow-up was 39 months. Fundus examination was performed under general anesthesia during comprehensive treatment and follow-up. The time interval of fundus examination varied from 1 to 6 months depending on the stability of the tumor.Results RRD was noted in 20 eyes (3.5%) with RB. Retinal hole was found in 15 eyes (75%). The cause of RRD was atrophic hole in calcified tumor (6 eyes, 30%), cryotherapy-related hole (5 eyes, 25%) and laser-related hole (9 eyes, 45%). Multiple atrophic hole in calcified tumor was noted in 3 eyes. Size of hole smaller than 2 DD was noted in 8 eyes (53%), and larger than 2 DD was noted in 7 eyes (47%). Holes were in posterior (3 eyes), equator (2 eyes) and periphery (10 eyes). Severe proliferated was noted in 1 eye. No tear was found. No bulbar retinal detachment and choroidal detachment was noted. Among 12 eyes who underwent vitreoretinal surgery, reattachment was achieved in 9 eyes (75%). No metastasis was noted.Conclusions Calcified regression of tumor, cryotherapy and laser were main reasons of RRD. Most of the holes are small in diameter and located in the periphery.

Objective To explore the outcomes of the oncology, the fertility and pregnancy on patients with early-stage cervical cancer after undergoing fertility-sparing treatments, and to investigate its value on clinical treatment. Methods A total of 29 patients with cervical cancer (stage Ⅰa2-Ⅰb1) who had undergone the fertility-sparing treatments in Renji Hospital, School of Medicine, Shanghai Jiaotong University from February 2010 to September 2015 were analyzed retrospectively. Surgical procedures included transvaginal cervical cold knife conization (CKC)+laparoscopic pelvic lymphadenectomy (PLD) or total laparoscopic uterine cervix extensive resection (RT; contains PLD); 48 patients with early cervical cancer under going laparoscopic uterine extensive resection (RH; contains PLD) by the same group of physicians in the same period were chosen as the control group. The perioperative related indicators, postoperative specimen examination, pregnancies after surgery and postoperative tumor follow-up results were retrospectively analyzed and compared between the two groups. Results (1) Among these 29 patients in the study group, 26 cases were underwent the fertility-sparing surgery quick frozen pathological examinations were positive in 3 cases, which underwent total laparoscopic RT eventually. (2) The perioperative related indicators: compared with the study group and the control group, the operation time [(182 ± 21), (147 ± 24) minutes, respectively] has significant difference (t=6.563, P<0.01). There were no significant difference (P>0.05) in intra-operative blood loss [(102±26), (99±34) ml], postoperative aerofluxus time [(1.3±0.4), (1.1±0.9) days], the average length of hospital stay [(11.2 ± 2.1), (10.6 ± 3.5) days], rate of urine retention [10%(3/29), 10%(5/48)] and rate of postoperative infection [3%(1/29), 2%(1/48)]. (3)Postoperative specimen examination:compared with the study group and the control group, there were no significant difference (P>0.05) innumber of removed lymphatic nodes (23.4 ± 4.1, 22.8 ± 3.9), length of cardinal ligament [(2.9 ± 0.5), (3.0 ± 0.6) cm], lengthof uterosacral ligament [(2.6±0.7), (2.8±0.4) cm], length of removed vaginal [(3.4±0.3), (3.5±0.3) cm]. (4) Pregnancies after surgery and postoperative tumor follow-up results:in the study group, only 14 patients had fertility requirement after treatments. Pregnancies occurred in 5 women (5/14), which included1 case of full-term labor, 1 case of preterm labor, and 3 cases of spontaneous abortion. The Average follow-up time in postoperative patients of the study group and control group was 29.4, and 30.2 months respectively. In follow-up period, compare with study group and the control group, there was no significant difference (χ2=0.004, P>0.05) in the recurrence rate [4%(1/26), 4%(2/48)]. Conclusion Fertility-sparing surgery of early-stage cervical cancer is safe but the outcome of the fertility and pregnancy is still need toimprove.

Objective To observe the application value and therapeutic efficacy of wide-field digital pediatric retinal imaging system (Retcam Ⅲ) fundus fluorescein angiograms (FFA) assisted photocoagulation on familial exudative vitreoretinopathy (FEVR).Methods The study included 46 eyes of 34 patients with staging 2 FEVR.All patients received color fundus photography and FFA under general anesthesia.The blood vessel reliability of color fundus photography and FFA was comparatively determined.Binocular indirect ophthalmoscope laser photocoagulation was applied to peripheral retina with abnormal leakage as indicated by FFA,the wavelength was 532nm,the duration was 0.25 s and the energy was 200-280 mW.After laser photocoagulation,fundus imaging and FFA was repeated.Further laser photocoagulation was immediately added to areas with vessel leakage but missing the photocoagulation.After treatment,the mean follow-up duration was 14.4 months.The follow up focused on neovascularization,exudative lesions,vitreous traction and merging of photocoagulation spots within 3 months,and on fibrosis membrane resulting in macular traction,tractional retinal detachment,vitreous hemorrhage or Coats disease-like retinal exudates after 3 months.Results It was hard to identify the blood vessels based on the color fundus images and some avascular zone maybe missed.Neovascularization can't be determined by shape of the blood vessels.On the other hand,those new blood vessels can be easily recognized by FFA as leakage sites at the boundary of avascular zone.The surgeon could quickly and accurately locate the FEVR area guided by the color fundus images and FFA from same angle under binocular indirect ophthalmoscope.During the treatment,there was no retinal FEVR area missed laser photocoagulation for all patients.There was no neovascularization,exudative lesions,vitreous traction within 3 months,and no fibrosis membrane,tractional retinal detachment,vitreous hemorrhage or Coats disease-like retinal exudates after 3 months.There were no ocular and systemic complications during and after the FFA and laser photocoagulation.Conclusion Wide-field Retcam Ⅲ FFA can help retinal specialists to identify abnormal neovascularization,locate the lesion area,and thus increase the success rate of laser photocoagulation,reduce the ocular and systemic complications for FEVR.
