【Objective】 To develop a clinical prediction model based on 68Ga-prostate-specific membrane antigen-11 (68Ga-PSMA-11), positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance imaging (mpMRI) parameters to stratify prostate cancer patients undergoing targeted biopsy, so as to avoid unnecessary systematic biopsy. 【Methods】 A total of 96 clinically significant prostate cancer (csPCa) patients who underwent 68Ga-PSMA-11 PET/CT and mpMRI prior to prostate targeted biopsy with systematic biopsy during Jan.2020 and Feb.2023 in Nanjing Drum Tower Hospital were retrospectively analyzed.By univariate and multivariate logistic regression analyses, maximum standard uptake value (SUVmax) in 68Ga-PSMA-11 PET/CT and minimum apparent diffusion coefficien (ADCmin) in mpMRI, as well as clinical parameters were evaluated to identify the independent predictors correlative with the effective diagnosis of targeted biopsy, and a clinical prediction model was constructed. 【Results】 Multivariate logistic regression analysis showed that SUVmax (OR=0.878, 95%CI: 0.804-0.959, P=0.004) and ADCmin (OR=1.005, 95%CI:1.001-1.010, P=0.027) were independent predictors of the effective diagnosis of targeted biopsy alone.The sensitivity, specificity, accuracy and area under the receiver operator characteristic curve (AUC) of the model were 0.80, 0.80, 0.83 and 0.84, respectively. 【Conclusion】 The clinical prediction model based on 68Ga-PSMA-11 PET/CT and mpMRI parameters is helpful to improve the effective diagnosis of targeted biopsy alone, and has practical value to stratify patients with csPCa so as to safely avoid systematic biopsy and effectively balance the benefits and risks.

Objective To compare the survival outcomes of bladder cancer with non-pure urothelium(BCa with n-pU)and bladder cancer with pure urothelium(BCa with pU)treated with robot-assisted radical cystectomy(RARC).Methods Clinical data of BCa patients treated with RARC in Nanjing Drum Tower Hospital during Oct.2014 and Mar.2022 were retrospectively analyzed.The patients were divided into n-pU group and pU group.After the baseline differences between groups were balanced with propensity score matching(PSM),the overall survival(OS)and recurrence-free survival(RFS)curve were plotted using Kaplan-Meier method and compared using Log-rank test.Univariate and multivariate analysis were performed with Cox model to identify the influencing factors of prognosis.Based on the results,a secondary grouping was performed to compare the survival differences between subgroups and further investigate the prognostic factors.Results After PSM,there were 53 pairs of BCa patients.There were no significant differences in the baseline data between the pU and n-pU groups(P<0.05).Regardless of T stage,there were no significant differences in OS and RFS between the two groups(P=0.217,P=0.109).Univariate Cox regression analysis showed that T stage(>T2)was a significant risk factor of OS and RFS(P<0.05).In the early pathological stage(≤T2),there were no significant differences in OS and RFS(P=0.565,P=0.344).In the advanced pathological stage(>T2),the OS and RFS of n-pU were significantly worse than those of pU patients(P=0.025,P=0.034).Conclusion The prognosis of BCa patients with n-pU who received RARC is significantly correlated with pathological status.At>T2 stage,n-pU patients have worse prognosis than pU patients in the same pathological status.

Objective:To analyze the prognostic factors of robot-assisted radical cystectomy (RARC).Methods:The clinical data of 224 patients underwent RARC from December 2014 to December 2018 in Nanjing Drum Hospital were reviewed. There were 193 males and 31 females, aged 36-92 years, with mean of 68 years. There were 7 patients(3.1%)undergoing neoadjuvant chemotherapy, the ASA scores of 125 patients (55.8%) were more than 2, and the mean body mass index was 23.4(15.4-35.5)kg/m 2. All patients were treated with RARC, with 72(32.1%) patients undergoing intraoperative blood transfusion. Kaplan-Meier method was used to analyze recurrence-free survival rate (RFS), cancer-specific survival rate (CSS) and overall survival rate (OS). Cox multivariate risk ratio model was used to evaluate the correlation between survival outcome and perioperative and pathological factors in patients treated with RARC. Results:For pathological status, there were 82 of ≤T 1, 64 of T 2, 57 of T 3 and 21 of T 4. Of all the patients, 49(21.9%) had lymph node metastasis, 12(5.4%) had positive surgical margin, 82(36.6%) had lymphovascular invasion(LVI), and 41(18.3%) underwent adjuvant chemotherapy. Follow-up time was between 11-60 months, and the median follow-up time was 24 months. The 5-year cumulative OS, RFS and CSS were 57.15%, 48.84% and 59.60%, respectively. Univariate Cox regression analysis showed that T stage( HR=5.764, 95% CI 1.926-17.249, P=0.002; HR=4.086, 95% CI 1.611-10.364, P=0.003; HR=9.391, 95% CI 2.118-41.637, P=0.003), N stage( HR=6.446, 95% CI 3.438-12.087, P<0.001; HR=5.661, 95% CI 3.086-10.385, P<0.001; HR=5.980, 95% CI 2.982-11.992, P<0.001), LVI( HR=3.319, 95% CI 2.008-5.486, P<0.001; HR=2.894, 95% CI 1.782-4.701, P<0.001; HR=3.471, 95% CI 2.017-5.974, P<0.001), American Society of Anesthesia (ASA)score( HR=2.888, 95% CI 1.619-5.150, P<0.001; HR=1.765, 95% CI 1.060-2.940, P=0.029; HR=2.612, 95% CI 1.424-4.792, P=0.002), body mass index( HR=0.886, 95% CI 0.819-0.957, P=0.002; HR=0.885, 95% CI 0.819-0.955, P=0.002; HR=0.862, 95% CI 0.792-0.938, P=0.001), age( HR=1.580, 95% CI 1.250-1.997, P<0.001; HR=1.362, 95% CI 1.088-1.705, P=0.007; HR=1.530, 95% CI 1.190-1.968, P=0.001) and intraoperative blood transfusion( HR=1.899, 95% CI 1.160-3.108, P=0.011; HR=2.218, 95% CI 1.371-3.587, P=0.001; HR=2.227, 95% CI 1.312-3.782, P=0.003) were significantly related to survival outcome. Multivariate Cox regression analysis showed that T stage( HR=4.506, 95% CI 1.433-14.175, P=0.01; HR=3.159, 95% CI 1.180-8.454, P=0.022; HR=7.810, 95% CI 1.674-36.444, P=0.009), N stage( HR=6.096, 95% CI 2.981-12.467, P<0.001; HR=5.368, 95% CI 2.683-10.740, P<0.001; HR=5.539, 95% CI 2.497-12.288, P<0.001) and ASA score( HR=6.180, 95% CI 2.371-16.110, P<0.001; HR=2.702, 95% CI 1.175-6.215, P=0.019; HR=6.471, 95% CI 2.290-18.286, P<0.001) were independent predictors of RFS, CSS and OS, and adjuvant chemotherapy( R=0.434, 95% CI 0.202-0.930, P=0.032) could only predict OS. Conclusion:T stage, N stage and ASA were main independent predictors of postoperative survival outcomes, and adjuvant chemotherapy was independent predictor of OS.

Objective:To analyze the diagnostic efficacy of targeted biopsy (TB) versus targeted biopsy combined with systematic biopsy (TB+ SB) for patients with multi-parametric magnetic resonance imaging (mpMRI) prostate imaging-reporting and data system (PI-RADS) score of 4-5.Methods:The clinical data of 378 patients with mpMRI PI-RADS score of 4-5 in Nanjing Drum Tower Hospital from January 2018 to February 2020 who received prostate TB+ SB were retrospectively analyzed. Median age was 69 (64, 75) years old, median prostate specific antigen was 9.5 (6.7, 16.3) ng/ ml, and median prostate volume was 34.1 (23.5, 48.4) ml. There were 240 cases with PI-RADS score of 4 and 138 cases with PI-RADS score of 5. Evaluating Gleason score of positive biopsy pathology and using χ 2 test or Fisher exact test to analyze the detection of prostate cancer (PCa) and clinically significant prostate cancer(CsPCa) by TB versus TB+ SB. Results:Of the all 378 cases, 88 cases (23.3%) were negative and 290 cases (76.7%) were positive. The average number of needle for TB was 2.4 per person, while SB was 12 per person. TB and SB had no statistically significant difference in the detection rate of PCa (73.3% vs. 68.3%, P=0.129) and CsPCa (55.8% vs. 49.7%, P=0.094) and in the accuracy (79.1% vs. 77.8%, P=0.658), but had a statistically significant difference in the positive rate (64.2% vs. 23.1%, P < 0.001). The pathological coincidence rate of TB and TB+ SB was 92.3%. There was no statistical difference in the detection rate of PCa (73.3% vs. 76.7%, P=0.275) and CsPCa (55.8% vs. 62.2%, P=0.076) between TB and TB+ SB. The missed diagnosis rate of TB for PCa was 4.5%, for CsPCa was 10.2%. For patients with PI-RADS score of 4, TB had no significant difference in the detection rate of PCa (65.4% vs. 69.2%, P=0.381) and CsPCa (46.7% vs. 52.9%, P=0.171) from TB+ SB. The accuracy of TB was 82.1%. The missed diagnosis rate of TB for PCa was 5.4%, for CsPCa was 11.8%. For patients with PI-RADS score of 5, TB had no significant difference in the detection rate of PCa (87.0% vs. 89.9%, P=0.452) and CsPCa (71.7% vs. 78.3%, P=0.211) from TB+ SB. The accuracy of TB was 73.9%. The missed diagnosis rate of TB for PCa was 3.2%, for CsPCa was 8.3%. Conclusions:For high-risk prostate cancer patients with PI-RADS score of 4-5, TB can obtain a detection effect similar to that of TB+ SB with fewer needles, but there is still the possibility of inaccurate diagnosis and missed diagnosis.
6.Identifying critical state of breast cancer cell differentiation based on landscape dynamic network biomarkers.
Journal of Biomedical Engineering 2020;37(2):304-310
Breast cancer is a malignant tumor with the highest morbidity and mortality in female in recent years, and it is a complex disease that affects human health. Studies have shown that dynamic network biomarkers (DNB) can effectively identify critical states at which complex diseases such as breast cancer change from a normal state to a disease state. However, the traditional DNB method requires data from multiple samples in the same disease state, which is usually unachievable in clinical diagnosis. This paper quantitatively analyzes the time series data of MCF-7 breast cancer cells and finds the DNB module of a single sample in the time series based on landscape DNB (L-DNB) method. Then, a comprehensive index is constructed to detect its early warning signals to determine the critical state of breast cancer cell differentiation. The results of this study may be of great significance for the prevention and early diagnosis of breast cancer. It is expected that this paper can provide references for the related research of breast cancer.

Objective Castleman′s disease ( CD) is a rare lymphoproliferative disorder, which has a very high misdiagnosis rate according to its lack of clinical and imaging specificity.The study was to improve the recognition, diagnosis and management of this disease by analyzing the clinicopathological characteristics and concluding diagnosis and treatment as well as literature review. Methods Retrospective analysis was conducted on clinical data of 31 CD patients (13 males and 18 females) who were hospitalized in the Affiliated Drum Tower Hosipital to Medical college of Nanjing University from January 2006 to Feburary 2014.Their mean age was (47.4 ±13.3) years.There were 24 cases with unicentric Castleman′s disease (UCD) and 7 cases with multicentric Castleman′s disease ( MCD) .UCD tended to be present in the form of an enlarged and painless mass which generally remained asymptomatic by accidental touch or regular physical examination.MCD was usually associated with constitutional symptoms.All the 24 patients with UCD underwent complete surgical resection.7 patients with MCD received different treatment methods, such as surgical resection, ste-riod and rituximab in combination with chemotherapy ( CHOP) . Results Postoperative pathology confirmed 23 cases were hyaline vascular type while 8 were plasma cell type.25 cases had been followed up (46.3 ±32.3) months after operation, among which 1 UCD case died of pancreatic head carcinoma 13 months after operation, 1 case with MCD plus pemphigus died 2 months after surgical resection of retroperitoneal lymphadenectasis, another MCD case died in 1 month without any treatment.The remaining 22 cases were alive. Conclusion CD is lack of clinical specificity and its diagnosis should be made by pathology.Each subtype differ greatly in prognosis, therefore different treatments should be taken after definitive subtype diagnosis.

OBJECTIVETo analyze the results of transperitoneal and retroperitoneal laparoscopic ureteroureterostomy procedure in the treatment of patients with retrocaval ureter.
METHODSFrom May 2004 to December 2012, 18 patients including 12 male and 6 female patients were operated for retrocaval ureter, the average age was (37 ± 10) years (range 17-55 years). Eight patients underwent transperitoneal laparoscopic ureteroureterostomy (transperitoneal laparoscopic group), and the other 10 patients' laparoscopic procedure were performed via retroperitoneal approach(retroperitoneal laparoscopic group). These patients' records were retrospectively analyzed for perioperative characteristics, complications and follow-up results. A two-tailed Student's t-test was used to compare perioperative data between the two groups.
RESULTSTechnical success was acquired in all 18 laparoscopic procedures. Mean operative time of transperitoneal and retroperitoneal laparoscopic group was (85 ± 20) minutes (60-130 minutes) and (98 ± 30) minutes (70-180 minutes) , respectively. There was no difference in operation time between the two groups (t = 1.03, P > 0.05). The blood loss was less than 50 ml in all the patients. Comparison of anal exhaust time between the two groups showed no statistic difference (t = 0.16, P > 0.05). No perioperative complication was observed. Intravenous pyelography or CT urography 3 months after the operation revealed a widely patent anastomosis with considerable improvement in hydronephrosis in all patients. There was no recurrence at a mean follow up of (40 ± 24) months (range 12-115 months).
CONCLUSIONBoth transperitoneal and retroperitoneal laparoscopic ureteroureterostomy are effective and minimally invasive surgical alternative for the management of retrocaval ureter.
