Objective To explore the diagnosis and treatment of penile verrucous carcinoma,a distinctive variant of squamous cell carcinoma. Methods The clinical data of 8 patients (mean age,46 years) with penile verrucous carcinoma were analyzed retrospectively.All the tumors showed exophytic,papillary lesions,ranging from 2 to 6 cm in the greatest dimension.The tumors were located at glans in 5 patients and invaded to shafts in the other 3.The diagnosis was established by biopsy of the lesion.Three patients with tumor invading to shafts and 1 patient with large tumor at glans underwent partial penectomy, while the other 4 with the tumors localized at glans were treated by local excision. Results Histopathologic examination of the specimens confirmed tumors-free surgical margins in all the cases.The tumor cells were mostly well-differentiated.Fourteen months postoperatively,local recurrence occurred in 1 patient with local excision and partial penectomy was performed; postoperative follow-up of 9 years showed no recurrence and metastasis. During a follow-up of 4 to 13 years,the other 7 patients were disease-free.The patients with local excision of the tumors reported satisfaction of their sexual lives. Conclusions Verrucous carcinoma of penis is characterized by slow growth and a locally aggressive nature.It seldom develops metastasis to regional lymph nodes or distant areas.The prognosis is favorable after appropriate treatment.

Objective To evaluate the predictive value of ABCD3-I score for early stroke risk after transient ischemic attack (TIA). Methods A total of 136 consecutive patients with TIA admitted to the Department of Neurology,the First Hospital of Shangqiu from January 2010 to December 2012 were enrolled. The clinical data,medical history and image findings of the patients were collected. The incidence of stroke was observed within 90 days. The occurrence of stroke risk after TIA were scored with the ABCD2 and ABCD3-I. Logistic regression analysis was used to analyze the impact of risk factors for early stroke after TIA. The area under the curve (AUC)of receiver operating characteristic was used to compare the predictive values of the two kinds of scores. Results Of the 136 eligible patients with TIA,19 cases (14. 0%)had cerebral infarction within 90 days after TIA. There were no death and hemorrhagic stroke. The results of multivariate regression analysis showed that the duration of TIA≥60 min (OR,1. 060,95%CI 1. 012-1. 112)was an independent risk factor for early progressing stroke after TIA (P<0. 05). In the ABCD2 scoring model for risk stratification of low-,moderate-,high-risk groups,the incidences of stroke within 90 days were 5. 6%(4/72),18. 5%(10/54),and 50. 0%(5/10),respectively. In the ABCD3-I score model for risk stratification of low-,moderate-,high-risk groups,the incidences of stroke within 90 days were 0,7. 1%(6/84),and 52. 0%(13/25),respectively. In the low-,moderate-,high-risk groups,there were significant differences in the incidences of stroke in 90 days between the ABCD3-I and ABCD2 scoring models (P<0.01). The AUC of ABCD3-I score (0. 839,95%CI 0. 766-0. 896)was higher than that of ABCD2 score (0.783,95%CI 0. 704-0. 849;P<0. 01). Conclusion The ABCD3-I score may effectively predict the risk of early stroke after TIA,and its accuracy is better than ABCD2 score.

Objective To review the diagnosis and treatment of basal cell carcinoma of the scrorum. Methods Clinical data of 7 patients with basal cell carcinoma of the scrotum were analyzed retrospectively. The mean age of the patients was 66 years. The most common presenting symptom was a plaque or nodular lesion with pruritis on the scrotum. The lesions ranged from 1.5 cm to 4.5 cm in diameter. Five of the 7 patients had a history of misdiagnosis. The diagnosis was established by biopsy of the lesion in all the patients. All of the 7 patients had no distant metastasis at the time of diagnosis and were treated by wide surgical resection.Results Histopathologic examination of the specimens confirmed the negative surgical margins in all cases.The most common histological feature was lobules, columns, bands and cords of basaloid cells associated with a surrounding loose fibromucinous stroma.One patient developed left inguinal lymph node metastasis at 21 months postoperatively,and was treated by bilateral inguinal lymph node dissection.The patient was free of cancer for 36 months after that. Another patient developed lung metastasis 48 months after the first operation.He was treated by systemic chemotherapy with cyclophosph amide, epirubicin and cisplatin for 6 cycles and obtained complete remission.This patient was free of cancer for 13 months after the chemotherapy.The remaining 5 patients were all free of cancer after the operation. Conclusions Basal cell carcinoma of the scrotum is rare.Wide surgical resection alone is usually considered to be curative. Because of its potential of metastasis, long-term followup is indicated for this disease.

OBJECTIVETo study the clinicopathologic features, differential diagnosis and prognosis of proliferative nodules(PNs) in congenital melanocytic nevi(CMN).
METHODSHistopathologic evaluation and immunohistochemical study by EnVision method were carried out in 8 cases of PNs in CMN. The clinical information and follow-up data were analyzed.
RESULTSThe age of patients ranged from 1 to 54 years (mean 27.6 years). Tumors were located on face (3 cases), on back (2 cases), upper extremities (2 cases) and lower extremities(1 case). Microscopically, PNs with expansile growth were observed in 8 cases of CMN. Melanocytes in PNs show variable pleomorphism with a mitotic activity of 0 to 4 per 10 high power fields. Blending of cells with adjacent CMN was noted in 6 cases. According to the morphology of melanocytes in PNs, it was classified into different types including large oval melanocytes (4 cases), small melanocytes (2 cases) and Spitz-nevus-like forms (2 cases). Immunohistochemically, melanocytes in PNs were consistent with those in adjacent CMN. They were diffusely positive for S-100 protein, but were either negative or focally positive for HMB45. Less than 5% of melanocytes were positive for Ki-67 in 8 cases of PN. Follow-up was available in all cases, ranging from 9 to 82 months. Seven patients with excision of single PN in CMN were alive with no evidence of disease, while 1 patient with multiple PNs in CMN was stable with disease after 62 months follow-up.
CONCLUSIONSPN is a rare melanocytic lesion arising in CMN. Recognition of its specific histologic features can help to avoid being misdiagnosed as melanoma. Long term follow-up should be recommended in patients with PNs, especially in those with atypical histologic features. Further investigation is needed to elucidate its clinical behavior.

OBJECTIVETo investigate the impact of androgen receptor splice variant 7 (AR-V7) expression on overall survival for patients with metastatic prostate cancer.
METHODSThe data of 113 diagnosed metastatic prostate cancer patients from January 2002 to June 2010 were collected retrospectively, including patient's age at diagnosis, prostate-specific antigen (PSA) level at diagnosis,Gleason score, clinical stage, PSA nadir during hormonal therapy, the time to PSA nadir, vital status, survival time and cause of death. The expression of AR-V7 in prostate cancer tissue was detected by using immunohistochemical staining. The correlation of AR-V7 expression and patient clinicopathological characteristics in all patients were analysed using Student t-test or Chi-square test. Cox proportional hazards regression models were used to evaluate the predictive role of AR-V7 expression and patient characteristics for overall survival.
RESULTSThe median PSA nadir was 0.7 µg/L (ranged from 0.0 to 143.0 µg/L). The median time to PSA nadir was 8.1 months (ranged from 0.9 to 71.0 months). The follow-up was performed until March 12, 2014. During the follow-up period, 67 of 113 metastatic prostate cancer patients (59.3%) died and the median overall survival was 96 months (ranged from 5 to 135 months). The AR-V7 detection rate was 20.4% (23/113). The serum PSA level in patients with positively expression of AR-V7 was significantly higher than that without AR-V7 expression (t = 2.521, P = 0.013). Multivariate Cox regression analysis indicated that the expression of AR-V7 (HR = 2.421, P = 0.002) and time to PSA nadir (HR = 1.019, P = 0.022) were independent prognostic factors of overall survival for metastatic prostate cancer patients.
CONCLUSIONSThe expression of AR-V7 in prostate cancer tissues and time to PSA nadir during hormonal therapy are independent prognostic factors of overall survival for metastatic prostate cancer patients. Therapy targeting AR-V7 may improve prognosis of metastatic prostate cancer patients.

Objective:To investigate the correlation and predictive value of serum miR-149-5p and matrix metalloproteinase-9 (MMP-9) and hemorrhagic transformation (HT) after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS received intravenous thrombolytic therapy in Shangqiu First People's Hospital from September 2019 to February 2022 were enrolled prospectively. They were divided into HT group and non-HT group according to whether HT occurred after intravenous thrombolysis. Serum miR-149-5p and MMP-9 were measured by real-time fluorescence quantitative polymerase chain reaction and enzyme-linked immunosorbent assay respectively. Multivariate logistic regression analysis was used to determine the independent risk factors for HT after thrombolysis. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum miR-149-5p, MMP-9 and their combination for HT after intravenous thrombolysis. Results:A total of 358 patients with AIS received intravenous thrombolytic therapy were enrolled, 71 of them (19.83%) developed HT. The serum MMP-9 in the HT group was significantly higher than that in the non-HT group (273.95±35.23 μg/L vs. 202.71±30.52 μg/L; t=17.062, P<0.001), while the serum miR-149-5p was significantly lower than that in the non-HT group (0.26±0.06 vs. 1.03±0.15; t=42.387, P<0.001). Multivariate logistic regression analysis showed that atrial fibrillation (odds ratio [ OR] 2.282, 95% confidence interval [ CI] 1.731-3.008; P<0.001), time from onset to intravenous thrombolysis ( OR 2.334, 95% CI 1.458-3.735; P<0.001), miR-149-5p ( OR 1.758, 95% CI 1.142-2.705; P=0.010) and MMP-9 ( OR 1.535, 95% CI 1.106-2.129; P=0.010) were the independent risk factors for HT after intravenous thrombolysis. Serum miR-149-5p (area under the curve 0.856, 95% CI 0.803-0.909; when the optimal cut-off value was 0.741, the sensitivity was 80.3% and the specificity was 89.9%), MMP-9 (area under the curve 0.875, 95% CI 0.821-0.929; when the optimal cut-off value was 240.051 μg/L, the sensitivity was 83.1% and the specificity was 90.2%) and their combination (area under the curve 0.897, 95% CI 0.854-0.941; sensitivity 84.5% and specificity 90.6%) had better predictive value for HT after thrombolysis, and there were no significant differences in the predictive value among the three. Conclusions:After intravenous thrombolysis, the serum miR-149-5p is lower and MMP-9 is higher at admission in patients with HT in patients with AIS. Both of them and their combination have better predictive value for HT after intravenous thrombolysis.

OBJECTIVETo analyze the risk factors to impact biochemical recurrence after radical prostatectomy.
METHODSA total of 1 090 patients who received radical prostatectomy from May 2002 to December 2013 in Department of Urology of Fudan University Shanghai Cancer Center were recruited. The average age of the patients was 67.9 years (ranged from 41 to 84 years) and the average preoperative prostate specific antigen (PSA) level was 32.7 (ranged from 3.2 to 256.3) µg/L. The distribution of patients with respect to clinical stage was: 20.09% (219/1 090) had T1, 50.09% (546/1 090) had T2 and 29.82% (325/1 090) had T3. The biochemical-free-survival curve was drawn by Kaplan-Meier method and the univariate and multivariate Cox regression models were used to evaluate the clinical and pathological variables for the development of biochemical recurrence.
RESULTSOf all the 1 090 patients, the biochemical recurrence free survival was 95.99%, 81.90% and 70.89% at 1, 3 and 5 years. PSA level at diagnosis (P=0.000), neo-adjuvant hormonal therapy (P=0.001), pre-operative Gleason score (P=0.000), clinical stage (P=0.010), surgical margin status (P=0.028), post-operative Gleason score (P=0.000), pathological stages (P=0.000) and pelvic lymph-node metastasis (P=0.000) were associated with biochemical recurrence in the univariate analysis. However, in the multivariate analysis, only PSA level at diagnosis (P=0.000), pre-operative Gleason score (P=0.020), pathological stages (P=0.014) and pelvic lymph-node metastasis (P=0.017) were independent prognostic factors.
CONCLUSIONFor the patients who received radical prostatectomy, PSA level at diagnosis, pre-operative Gleason score, pathological stages and pelvic lymph-node metastasis status are independent prognostic factors for biochemical recurrence.

Objective:
To explore the predictive value of circulating tumor cells (CTCs) characterization for time to castration resistance of newly diagnosed high volume metastatic castration sensitive prostate cancer (mCSPC) patients.
Methods:
Newly diagnosed high volume mCSPC patients were prospectively enrolled in this study from September 2015 to February 2017. The inclusion criteria include that the patients' age should be between 18 to 85 years old. The Prostate cancer should be diagnosed by biopsy or cytopathology. No endocrinological therapy, radiative therapy or chemotherapy was used before the study. High-volume metastatic lesion was confirmed by imaging. Those patients who accepted previous endocrinological therapy, radiative therapy or chemotherapy were excluded in this study. Those patients combined with concomitant tumor were also excluded. The health males were enrolled in the control group. All patients received androgen deprivation therapy (ADT) with goserelin plus bicalutamide (goserelin 3.6 mg subcutaneous injection, once a month plus bicalutamide 50mg orally, once a day). CanPatrol system was used to count CTCs in peripheral blood of patients and characterize CTCs based on expressions of epithelial markers(EpCAM and CK8/18/19) and mesenchymal markers(vimentin and twist). Primary endpoint was time to castration resistance. Survival analysis was conducted using Kaplan-Meier method and log-rank test was used to assess the difference of survival between groups, and univariate and multivariate analyses of prognostic factors were conducted using the Cox proportional hazards model.
Results:
A total of 108 newly diagnosed high volume mCSPC patients were enrolled in this study. The median age of enrolled patients was 68 years old (ranging 51-85 years old), and median PSA was 196.2 ng/ml(ranging 5.8-5 011.9 ng/ml). The median level of hemoglobin was 32 g/L(ranging 9-172 g/L). The median level of LDH was 179 U/L(ranging 49-630 U/L). The ECOG scores was 0-1 score in 94 cases(87.0%), 2 scores in 14 cases (13.0%). The Gleason scores was 6-7 in 20 cases (18.5%) and more than 8 in 88 cases (81.5%). All patients had bone metastatic lesions, among which 41 (38.0%) patients had more than 10 metastatic lesions and 6 (5.6%) patients with visceral metastasis, 30(27.8%) patients with limb bone metastasis. The median CTCs count was four, and ranging 0-35. Mesenchymal CTCs positive and negative (negative included CTCs negative, epithelial CTCs positive and biophenotypic CTCs positive) patients were 58(53.7%) and 50, respectively. There was no correlation between CTCs characterization with age, baseline PSA, Gleason score, ALP and other clinical parameters (
