ABSTRACT
Objective To investigate the clinical features,pathology and prognostic factors of young patients with cervical cancer less than 35 years old.Methods One hundred and twenty cases cervical cancer less than 35 years old were selected as study group,while 120 cases of cervical cancer over 35 years old as control group in the same period.The clinical features and pathology were compared between two groups and risk factors were analyzed.Results The proportion of contact vaginal bleeding,menstrual disorders,mild cervical erosion,HPV infection,and the number of pregnancy preserving ovarian surgery in study group were significantly higher than that in control group(60.8％(73/120)vs.47.5％(57/120),30.0％(36/120)vs.11.7％(14/120),57.5％(69/120)vs.23.3％(28/120),81.7％(98/120)vs.60.0％(72/120),52.5％(63/120)vs.25.8％(31/120)),the differences were statistically significant(x2=4.30,12.23,29.90,13.63,17.91;P＜0.05).The incidence of irregular vaginal bleeding in study group was significantly lower than that in control group(6.7％(8/120)vs.15.8％(19/120)),the differences was statistically significant(x2=5.05,P＜0.05).The main pathological types of two groups were squamous cell carcinoma,non squamous cell carcinoma rate in study group was significantly higher than that in control group(27.5％(33/120)vs.15.0％(18/120)),the differences was statistically significant(x2=5.60,P＜0.05).Pelvic lymph node metastasis rate in study group was 68.3％(82/120),significantly higher than that in control group(55.0％(66/120),x2=4.49,P＜0.05).Multivariate analysis of prognostic factors in young patients with cervical cancer showed that clinical stage,pathological type,depth of cervical invasion and pelvic lymph node metastasis were independent risk factors for the prognosis of young patients with cervical cancer(Wald x2=4.02,6.93,8.92,10.87;OR=3.22,5.57,6.84,5.48;95％CI=1.13-8.62,1.24-11.75,2.82-17.35,1.88-12.35,P＜0.05).Conclusion There are some differences in the clinical features and pathological characteristics of young patients with cervical cancer and middle-aged and elderly patients with cervical cancer.More attention should be paid on the high clinical staging,non squamous cell carcinoma,deep cervical infiltration positive pelvic lymph node metastasis patients,focus on the investigation and prevention,improve the individual treatment and prevention and control system.
