title: [Present epidemiological status and clinical characteristics of cervical cancer in Beijing: a report of 1399 patients].
abstract: OBJECTIVE
  To analyze the prevalence and clinical characteristics of hospitalized patients with cervical cancer over the last two decades in Beijing so as to provide scientific rationales for the management of cervical cancer.
  
  
  METHODS
  Stratified cluster sampling was employed to analyze a total of 1399 invasive cervical cancer cases from different class hospitals in Beijing during the period of 1990 - 2009.
  
  
  RESULTS
  (1) The number of cervical cancer cases had been rising over the last 2 decades. (2) The age of onset ranged from 17 to 88 years old; the number of patients with stages I, II, III and IV was 772 (57.1%), 380 (28.1%), 182 (13.5%) and 18 (1.3%) respectively; 1135 (83.1%) patients were of squamous cell carcinoma while 182 (13.3%) adenocarcinoma. The last two decades was divided into 4 groups of 5 years each. The average age gradually decreased from 58.2 to 46.0 years old (P < 0.01). The proportion of patients with stages I and II also increased from 69.6% (16/23) to 89.4% (530/856); There was no significant change in histopathologic type of cervical cancer. And squamous cell carcinoma of cervix remained the predominant type (P > 0.05). (3) About 26.0% (364/1399) of cases received no vagino-recto-abdominal examination while 3.4% (48/1399) of cases were not staged.
  
  
  CONCLUSIONS
  Over the last two decades, the number of newly diagnosed cervical cancer cases has showed a rising trend in Beijing. And the proportions of young patients and patients with early disease have both increased. Some irregularities still exist in the diagnosis of cervical cancer. So we should pay more attention to the screening program and standardize the diagnosis, therapy and follow-up of cervical cancer.
