[Clinical application of adult comorbidity evaluation-27 in endometrial cancer]

Objective: To investigate the significant role of the clinical application of adult comorbidity evaluation-27 (ACE-27) in endometrial cancer (EC). Methods: A total of 847 EC patients were included during Jan. 1985 to Dec. 2015 from Tianjin Medical University General Hospital. The clinical data of the patients were collected and analyzed retrospectively. All of the patients were received operation with no chemotherapy and radiotherapy before operation. The average age was 57.6 years old (range from 25 to 85 years old). The average follow-up period was 59.0 months (range from 2 to 312 months). The comorbidity of the patients was evaluated by ACE-27. EC patients survival was analyzed by Kaplan-Meier survival curve. The relationship between the prognosis of EC and ACE-27, age, body mass index (BMI) , pathological characteristic were showed by Cox modeling. Results: (1) The patient number of score 0, 1, 2 and 3 of ACE-27 in EC patients were respectively 311 (36.7%), 263 (31.1%), 132 (15.6%) and 141 (16.6%) cases. (2) Kaplan-Meier survival curve analysis showed that overall survival time of EC patients was gradually decreased as increased score of ACE-27 (χ²=19.003, P=0.000) . In the patients of BMI<25 kg/m² and BMI 25-<30 kg/m², International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ, endometrial adenocarcinoma type and the overall survival time of those EC patients were gradually decreased as increased score of ACE-27 (P<0.05) . However, there was no statistically significant difference in overall survival time for patients with BMI ≥30 kg/m², FIGO stage with Ⅱ-Ⅳand non-endometrial adenocarcinoma type (P>0.05). Per unvariate logistic modeling showed that the risk of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 (OR=2.53, P=0.000) . The overall survival time in EC patients with aged 50-59, 60-69 and ≥70 years old, BMI 25-<30 kg/m² and ≥ 30 kg/m², G₃, FIGO stage Ⅱ-Ⅳ and non-endometrial adenocarcinoma type were significantly decreased compared with those aged <50 years old, BMI < 25 kg/m², G₁, FIGO stage Ⅰ and endometrial adenocarcinoma type (all P<0.05) . Further we found that postoperative chemotherapy or radiotherapy rate were decreased for EC patients with FIGO staging Ⅲ or Ⅳ as the increase of ACE-27 score, but there was no statistically significant difference (P>0.05). (3) Per multivariate logistic modeling showed that the risks of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 among age-adjusted, BMI, histological grade, FIGO stage and pathologic type (OR=2.40, P=0.000) . Per multivariate logistic modeling showed that, the overall survival time in EC patients with aged 60-69 and ≥70 years old, BMI 25-<30 kg/m² and ≥30 kg/m², FIGO stage Ⅲ-Ⅳ and non- endometrial adenocarcinoma type remain significantly decreased compared with those aged <50 years old, BMI<25 kg/m², FIGO stage Ⅰ and endometrial adenocarcinoma type (P<0.05) , but there was no statistically significant difference in histological grade (P>0.05). Conclusions: ACE-27 may become one of the factors of predictive therapy and the prognosis for EC patients. The detailed clinical data of comorbidity should be collected to evaluate prognosis and therapy plan.
