Objective:
To investigate the independent predictors of inguinal lymph node metastasis (LLM) in patients with penile squamous cell carcinoma (SCCP), and to establish a nomogram for predicting individual LLM risk.
Methods:
The data of patients with SCCP diagnosed at the department of urology, Xijing Hospital from July 2009 to June 2019 were analyzed retrospectively. A total of 101 patients were included in this study, with age of 55 (26-84) years. There were 25 (24.8%) and 76 (75.2%) patients with and without palpable inguinal lymph node enlargement, respectively. There were 47 cases (46.5%), 40 cases (39.6%) and 14 cases (13.9%) in T1, T2 and T3 stages, respectively; there were 67 cases (66.3%), 21 cases (20.8%) and 13 cases (12.9%) in Broder 1, 2 and 3, respectively. The average value (or median) of fibrinogen was 2.84 (1.72-5.00)g/L; alkaline phosphatase was 80(32±214)U, hemoglobin was 147(81-180)g, platelet count was (193.74±65.68×109/L, absolute value of neutrophils, monocytes and lymphocytes were 3.98(1.19-11.85)×109/L, 0.44(0.17-1.90)×109/L and 1.68(0.58-4.13)×109/L, respectively. The average (or median) value of PLR, NLR and LMR were 113.38(18.80-418.42), 2.42(0.59-10.22) and 3.84 (1.08-9.89), respectively. There were 26 cases (25.7%) with LLM and 75 cases (74.3%) without LLM. The independent predictors of LLM were identified by univariate and multivariate logistic regression analyses. The R software was used to establish the nomogram by integrating all independent predictors, and the bootstrap method was used to internally validated our nomogram, where the value of AUC (area under the ROC curve) was calculated and the calibration plot was drawn.

Objective:To study the clinical characteristics of double aortic arch (DAA) combined with aortoesophageal fistula (AEF), and summarize the diagnosis and treatment experience.Methods:Retrospective analysis was performed on the diagnosis and treatment of a newborn with hemorrhagic shock caused by DAA combined with AEF in the Guangzhou Women and Children's Medical Center. The key searching words included "double aortic arch", "aortoesophageal fistula", "vascular ring", "newborn or neonate", and "infant, newborn". The relevant reports were retrieved from databases of CNKI, Wanfang, VIP, PubMed, Springer Link, Google Scholar, Web of Science, Embase, Cochrane Library and OVID, to summarize the clinical features, diagnosis and treatment experience of neonates with DAA and AEF. The retrieval deadline was December 31, 2020.Results:A full-term female newborn was hospitalized for dyspnea immediately after birth, and failed to evacuate from the ventilator for several times. The patient was fed with nasogastric tube and transferred to our hospital because of hemorrhagic shock occurring in 32 days after birth, and gastrointestinal bleeding occurred repeatedly with the maximum bleeding volume reaching 200 ml/time. DAA was diagnosed by cardiac ultrasound and CT, AEF hemorrhage was finally confirmed by gastroscopy, aortography and operation. DAA correction and esophagus repair were successfully performed, and the infant recovered well after the operation. At 9-month old, the infant grew and developed well. At present, no reports of DAA combined with AEF neonates have yet to be published in medical literatures in China. Seven English language literatures included 7 cases of AEF complicated with DAA in neonatal period, 5 cases survived and 2 cases died have so far been reported. All patients have a long history of gastric tube indwelling.Conclusions:The incidence of DAA combined with AEF is rare in the newborn with respiratory and swallowing difficulties as the first manifestation. The disease symptoms progressed rapidly, and life-threatening digestive tract hemorrhage may occur, which often requires surgical treatment. Prolonged gastric tube retention should be avoided in DAA children to prevent the occurrence of AEF.

Objective:To investigate the efficacy and safety of radium-223 in combination with new-generation hormonal agents in patients with bone metastases of prostate cancer.Methods:The clinical data of 17 patients (12 from the First Affiliated Hospital of Airforce Military Medical University and 5 from Xi'an International Medical Center Hospital) with metastatic castration-resistant prostate cancer(mCRPC) treated by radium-223 combined with new-generation hormonal agents from January 2021 to June 2022 were retrospectively analyzed. In all cases, the average age was (73.3±8.5) years old. Before treatment, the median prostate-specific antigen (PSA) was 15.7 (3.2, 36.5) ng/ml, the median alkaline phosphatase (ALP) was 131.5 (79.0, 430.7) U/L. All patients had ≥ 2 bone metastases but no visceral or lymph node metastases. The median number of bone scan lesions was 10(8, 15). Bone pain symptom was present in 16(94.1%) patients. There were 9 cases (52.9%) with Eastern Cooperative Oncology Group (ECOG) score of ≥2, 1 case (5.9%) with ECOG score of 1 and 6 cases (35.2%) with ECOG score of 0. All patients were treated with radium-223 (55 kBq/kg, injected every 4 weeks for a maximum of 6 cycles), of which 5 patients were combined with enzalutamide, 8 patients combined with apatamide and 4 patients combined with bicalutamide. PSA response (PSA decreased by ≥30% from baseline and maintained for at least 1 month), ALP response (ALP decreased by ≥30% from baseline and maintained for at least 1 month) and pain relief rates were analyzed. Imaging evaluation was performed before and after treatment to calculate the objective response rate of metastases. The incidence of treatment-related adverse effects and skeletal related event (SRE) were also recorded.Results:Eleven patients completed 6 courses, 3 patients completed 5 courses and 3 patients completed ≥4 courses. The median ALP after 1 month of last treatment was 83.2 (51.5, 126.5) U/L, which was significantly decreased than baseline. 12 patients (70.6%) showed an ALP response and the other 5 (29.4%) showed varying degrees of ALP elevation. PSA response was observed in 4 patients (23.5%), of which 2 (11.8%) had a continuous decrease and 2 (11.8%) had a late-stage increase in PSA. Pain relief was relieved in 15 cases (88.2%) during treatment, 1 case (5.9%) had worsening pain due to disease progression and 1 case (5.9%) had no change during treatment. The ECOG score decreased in 15 (88.2%) patients. The median number of bone metastases in patients decreased to 5 (4, 9). One patient (5.9%) had complete remission during treatment, 11 patients (64.7%) had a partial response, 4 patients (23.5%) were stable, and 1 (5.9%) showed imaging progression after 4 months of treatment. The overall objective remission response rate was 70.5% (12/17). Treatment-related hematologic adverse effects included anemia (1 case, 5.9%, grade 3), thrombocytopenia (1 case, 5.9%, grade 3) and leukopenia (1 case, 5.9%, grade 2). Non-hematologic adverse effects included fatigue (3 cases, 17.6%, 2 cases in grade 1, 1 case in grade 2), gastrointestinal bleeding (1 case, 5.9%, grade 3), diarrhea (1 case, 5.9%, grade 2) and fever (1 case, 5.9%, grade 1). Patients with grades 1 to 2 relieved with symptomatic management. Three cases (17.6%) were discontinued due to intolerance of grade 3 adverse reactions and 1 case (5.9%) terminated on its own. There was no SRE during treatment and follow-up.Conclusions:Radium-223 combined with New-generation hormonal agents has a high objective remission rate in patients with mCRPC, which could provide pain relief and improve quality of life. The incidence of adverse reactions was low and well tolerated.

Objective:
To investigate the pathological characteristics of bladder low malignant potential papillary urothelial tumors (PUNLMP) and the predic factors of recurrence and pathological progress.
Methods:
We retrospectively analyzed 150 patients of bladder PUNLMP in the Department of Urology of Xijing Hospital from February 2009 to February 2019. Among the 150 patients, 118 patients were males and 32 patients were females. The average age was 57 years, ranging 20-93 years. There were 112 cases of single tumor and 38 cases of multiple tumor. All patients received transurethral resection of bladder tumor (TURBT) and 136 patients received bladder infusion chemotherapy, including 61 patients for pirarubicin, 58 patients for gemcitabine, 11 patients for epirubicin, and 11 patients for mitomycin. 14 patients did not receive bladder infusion chemotherapy. In this study, univariate and multivariate logistic regression analysis were used to investigate independent predictors of recurrence and pathological progression in patients of bladder PUNLMP who received TURBT.
Results:
The average follow-up time was 25.6 months, ranging 5.5-122.7 months. Among the patients, 21 patients occurred recurrence. The recurrent duration ranged from 2.2 to 108.3 months (mean 23.1 months). 12 patients had pathological progression, including 9 patients for low-grade non-invasive papillary urothelial carcinoma, 1 patient for high-grade non-invasive papillary urothelial carcinoma, 1 patient for high-grade invasive urothelial carcinoma, 1 patient for squamous cell carcinoma. The progressive duration ranged from 2.2 to 56.3 months (mean 21.5 months). Among the 150 patients, 18 patients with inverted growth pattern did not recur. There were significant differences in the number of tumors and the tumor length between the recurrence and non-recurrence groups, same as the progression and non-progression groups. The univariate and multivariate logistic regression analysis results showed that the number of tumors was an independent predictor of tumor recurrence (
