Objective To analyze the clinical features and treatment and prognosis of Paget's diseases.Method 7 cases of Paget's disease of the extramammary have been encountered. Results 3 patients with groin matastases were died within 5 years, the patients without groin matastases were all surrived.Conclusions Surgery is the treatment of first choice for Paget's disease. Prognosis of patient with groin matastases is very poor.

Objective To assess the safety and the curative effect of the combination of minipercutaneous nephrolithotomy (mini-PCNL) and ureteroscopic lithotripsy (URL) in the treatment of nonhydronephrotic staghorn calculi. Methods The clinical data of 53 eases with non-hydronephrotic staghom calculi treated by mini-PCNL combined with URL were retrospectively analyzed. Results Fifty-three cases (64 renal units) were performed first-stsge operation, 9 renal units were stone free in first-stage operation, 33 renal units were stone free in second-stage operation, other 13 renal units were stone free in third-stage operation. A complete stone clearance rate of 85.9%(55/64) was achieved, and after one to three sessions of mini-PCNL and extracorpereal shock wave lithotripsy afterwards that increased to 95.3% (61/64). Blood transfusion was performed in 3 cases, no major complication was noted in the patients. Conclusions The combination of mini-PCNL and URL has more advantages, less invasions, easier recovery and less complications. It provides a new minimally invasive way for non-hydronephrotic staghorn calculi.

BACKGROUND AND OBJECTIVEBronchopulmonary carcinoid (BPC) account for less than 2% of all primary lung malignant tumors, but few related studies were reported. The aim of this study is to analyze this rare disease's clinicopathological characteristics.

METHODSThe clinical data of 28 patients with BPC in Cancer Center of Sun Yat-sen University, from January 1994 to June 2009, were enrolled into retrospective analysis. First, the corresponding paraffin blocks reexamined, slice up and stained, multiple pathologists re-consulted, and its subsets (typical carcinoid, TC; atypical carcinoid, AC) defined. Second, the clinical characteristics and immunohistochemical markers and its relationship with prognosis were analyzed.

RESULTSFirst, the 5-year survival for overall and TC, AC was 56% and 70%, 41% respectively in 28 cases. The markers CD99, Bcl-2 and Ki-67 expression correlated significantly with the BPC subsets (P = 0.017, P = 0.043, and P = 0.033 respectively). Further univariate analysis revealed that advanced TNM staging (P = 0.037), lymph node metastasis (P = 0.001) and Ki-67 nucleolus's positive expression (P = 0.009) are poor prognostic factors. Second, the overall, TC, AC 5-year survival rate was 73%, 83%, 57% respectively in 20 cases underwent the radically surgical resection. Further univariate analysis revealed that AC subset (P = 0.013), lymph node metastasis (P = 0.004) and Ki-67 nucleolus's positive expression (P = 0.006), advanced TNM staging (P = 0.047) are poor prognostic factors in this 20 cases. Third, as univariate analysis, local recurrence and metastasis (n = 4) correlate significantly with Ki-67 nucleolus's and Bcl-2 positive expression (P = 0.027, 0.045, respectively).

CONCLUSIONThe prognosis of BPC was better than other types of primary lung cancer. Ki-67, Bcl-2 high expression and advanced TNM staging are the poor recurrence and prognostic factors of BPC. The radical surgery remains the treatment of choice for resectable candidates in BPC as NSCLC.

The increasing number of pulmonary nodules being detected by computed tomography scans significantly increase the workload of the radiologists for scan interpretation. Limitations of traditional methods for differential diagnosis of pulmonary nodules have been increasingly prominent. Artificial intelligence (AI) has the potential to increase the efficiency of discrimination and invasiveness classification for pulmonary nodules and lead to effective nodule management. Chinese Experts Consensus on Artificial Intelligence Assisted Management for Pulmonary Nodule (2022 Version) has been officially released recently. This article closely follows the context, significance, core implications, and the impact of future AI-assisted management on the diagnosis and treatment of pulmonary nodules. It is hoped that through our joint efforts, we can promote the standardization of management for pulmonary nodules and strive to improve the long-term survival and postoperative life quality of patients with lung cancer.
