Methods： In total, 61,480 men aged 40-74 years from 2002 to 2006 and 74,941 women aged 40-70 years from 1997 to 2000 were recruited to undergo baseline surveys in urban Shanghai, with response rates of 74.0% and 92.3%, respectively. A Cox proportional hazards regression model was used to estimate relative risks （RRs） and 95% confidence intervals （95% CIs） of deaths associated with cigarette smoking. PARs and 95 % CIs for deaths were estimated from smoking exposure rates and the estimated RRs. Results： Cigarette smoking was responsible for 23.9% （95% CI： 19.4-28.3%） and 2.4% （95% Ch 1.6- 3.2%） of all deaths in men and women, respectively, in our study population. Respiratory disease had the highest PAR in men [37.5% （95% CI： 21.5-51.6%）], followed by cancer [31.3% （95% Ch 24.6-37.7%）] and cardiovascular disease （CVD） [24.1% （95% CI： 16.7-31.2%）]. While the top three PARs were 12.7% （95% CI： 6.1-19.3%）, 4.0% （95% CI： 2.4-5.6%）, and 1.1% （95% CI： 0.0-2.3%）, for respiratory disease, CVD, and cancer, respectively in women. For deaths of lung cancer, the PAR of smoking was 68.4% （95% CI： 58.2- 76.5%） in men. Conclusions： In urban Shanghai, 23.9% and 2.4% of all deaths in men and women could have been prevented if no people had smoked in the area. Effective control programs against cigarette smoking should be strongly advocated to reduce the increasing smoking-related death burden.展开更多

The results showed that thecancer-adjusted mortalities were 224.14/100000 and226.66/100000: it was 7 times as high as low-incidence(31.19/100000 and 29.82/100000). In 70s, the cancer deathof esophagus, stomach and liver (87.41/100000,73.93/100000 and 8.59/100000) were 28 times, 10 timesand 4 times as high as low-incidence area (3.70/100000,10.57/100000 and 1.94/100000), respectively (P<0.001). In80s, the cancer death of esophagus, stomach and liver(68.26/100000, 109.39/100000 and 23.89/100000) were 17times, 10 times and 4 times as high as low-incidence area(4.54/100000, 10.84/100000 and 6.35/100000), respectively(P<0.001). In high-incidence area, the cancer death ofesophagus was lower, of stomach and liver were higherin 80s than 70s, respectively (P<0.01)- The result alsoshowed that the nitrate content of drinking water andvegetables were 21.45mg/1 and 1185.27mg/kg in high-incidence area; it were significant higher than that in low-incidence area (2.14mg/1 and 41.6omg/kg), the nitritecontent (0.01mg/l) of drinking water in high-incidencearea was significant higher than that in low-incidencearea (0.004mg/l), but the nitrite content among vegetableswas no significant difference between the two regions(N0.05). Our results suggest that the nitrate and nitritecontents increase in drinking water and vegetables maybe an important risk factor of upper alimentary cancer inhigh-incidence area.展开更多

Methods: Patients admitted in our department from 2007 to 2015 who died during follow-up after surgery for HNOS were selected. Information concerning demographics,disease,treatment and follow-up were collected and analyzed. Results: A total of 77 patients died at a median age of 42 years old,of whom 33 were male and 44 female. Thirty-nine tumors were identified in the maxilla and skull base region while 38 in the mandible. Positive surgical margins were observed in 7 cases. Twenty patients received adjuvant chemotherapy,and 36 received postoperative radiotherapy. Local recurrence,as an initial cause of death,occurred in 25 cases,whilst metastasis occurred in the rest. Conclusion: Patients with HNOS benefit from negative surgical margins and adjuvant chemotherapy before death. Patients above 30 years old have longer disease-free survival,and patients with tumors of low pathological grade have longer overall survival. Tumor size and postoperative radiotherapy are negative prognostic factors. Frequent follow-up should be conducted for at least 48 postoperative months.展开更多
