Objective :
To analyze the trend of lung cancer incidence in Shaoxing, Zhejiang Province from 2014 to 2019, so as to provide the basis for lung cancer prevention and control.
Methods :
The data of lung cancer were collected through the information management system of chronic disease surveillance in Zhejiang Province.The crude incidence rate, age-standardized incidence rates by Chinese standard population ( ASIRC ) and by world standard population ( ASIRW ), truncated rate ( 35-64 ) years old ), and cumulative rate (0-74 years old) were calculated. The annual percentage change ( APC ) was used to analyze the trend of lung cancer. The annual contribution rate was used to analyze the contribution of the incidence trend with age to the total trend.
Results :
Totally 22 261 cases of lung cancer were reported in Shaoxing from 2014 to 2019. The crude incidence rate, ASIRC, ASIRW, truncated rate ( 35-64 years old ), and cumulative rate ( 0-74 years old ) were 83.51/100 000, 41.28/100 000, 41.01/100 000, 57.00/100 000 and 5.11%, respectively. The crude incidence rate, ASIRC and ASIRW increased significantly from 2014 to 2019, with the APC values of 8.56%, 6.42% and 6.05%, respectively ( P<0.05 ). The crude incidence rate, ASIRC, ASIRW, truncated rate ( 35-64 years old ), and cumulative rate ( 0-74 years old ) of man were 105.25/100 000, 48.09/100 000, 50.69/100 000, 62.03/100 000 and 6.42%, respectively, which were higher than those of women ( 61.84/100 000, 33.05/100 000, 31.35/100 000, 51.71/100 000 and 3.76% ).The crude incidence rate increased with age. The annual contribution rates of lung cancer incidence in people aged 15-<45 years, 45-<55 years, 55-<65 years and ≥65 years were 51.20%, 30.86%, 15.79% and 2.15%, respectively. The crude incidence rate in people aged 15-<45 years, 45-<55 years and 55-<65 years increased significantly from 2014 to 2019, with the APC values of 23.84%, 13.79% and 6.78%, respectively ( P<0.05 ).
Conclusion
From 2014 to 2019, the incidence of lung cancer in Shaoxing shows an increasing trend, and the age of onset is getting younger.

Background and purpose:The application of intensity-modulated radiotherapy (IMRT) has improved the local control rate of nasopharyngeal carcinoma greatly, which changed the predictive value of T classiifca-tions of TNM staging system. This study aimed to validate the predictive effect of T classiifcations in the 7th Union for International Cancer Control (UICC) staging system and discuss the simpliifcation of T classiifcations.Methods:We retrospectively reviewed the clinical data of 641 primary nasopharyngeal carcinoma patients at our center from January 2007 to June 2011. We evaluated the predictive effect of T classiifcations by Kaplan-Meier method and Cox regression model.Results:The 5-year overall survival (OS), local relapse-free survival (LRFS), progression-free survival (PFS) and distant metastasis free survival (DMFS) were 85.4%, 88.5%, 78% and 87.1%, respectively. The 5-year OS of T1, T2, T3 and T4 categories were 91.6%, 85.3%, 90.1% and 76.5%, respectively; LRFS were 93%, 85.3%, 91.5% and 84.4%; PFS were 88.2%, 77.3%, 80.8% and 70.9%; DMFS were 95.1%, 88.9%, 88.2% and 81.3%, respectively. The difference in survival curves between T1, T2 and T3 were not signiifcant (P>0.05). However, several prognostic indexes were signiifcantly different between T4 and T1, T2, T3. We merged the T1, T2 and T3 classiifcations as new T1, and the T4 classiifcation as new T2. The 5-year OS of new T1 and T2 were 89.1% and 76.5% (P=0.001); LRFS were 90.1% and 84.4% (P=0.028); PFS were 81% and 70.9% (P=0.001); DMFS were 90.8% and 81.2% (P=0.002). The survival curves were substantially separated. The simpliifed T classiifcations had obvious advantages when separately analyzed in different N stages.Conclusion:In the era of IMRT, the predictive effect of T classiifcations of the 7th UICC staging system has diminished. The simpliifcation of T classiifcations can ift with the new treatment and provide a better surviv-al prediction.

Objective:To evaluate the efficacy and safety of endoscopic papillectomy (EP) combined with endobiliary radio frequency ablation (RFA) for duodenal papilla tumor with intraductal biliary infiltration.Methods:Data of 12 patients with histologically confirmed duodenal papilla tumor combined with intraductal biliary infiltration treated by EP with RFA from February 2013 to February 2019 were retrospectively analyzed. Clinical characteristics,endoscopic features, treatment efficacy and postoperative complications of patients were reviewed and recurrence was followed up.Results:The median diameter of lesions measured by endoscopic ultrasound was 18.5 mm×15.5 mm, and the length of intrabiliary invasion was 14.1±5.8 mm. EP combined with RFA was successfully performed in all patients with a technical success rate of 100%. Postoperative pathology showed adenocarcinoma in 5 patients, adenoma with high-grade intraepithelial neoplasia in 6 patients, and adenoma with low-grade intraepithelial neoplasia in 1 patient. Patients received mean 4.1±1.6 times of ERCP with intraductal biopsy during a mean follow-up period of 28.5±10.4 months. Recurrence occurred in 2 patients at 14 and 20 months respectively, both were adenocarcinoma.Conclusion:EP combined with RFA is effective and safe for duodenal papilla tumor with intraductal biliary infiltration. However, given the risk of recurrence, close surveillance is recommended.
