[Short-term outcome of leuprorelin acetate in preventing recurrence of ovarian endometrioma after conservative surgery].

OBJECTIVE: To evaluate the short-term effect of leuprorelin acetate microspheres in preventing recurrence of ovarian endometrioma after conservative surgery. METHODS: From January 2011 to September 2011, 190 ovarian endometrioma patients undergoing conservative laparoscopic surgery at Affiliated Obstetrics and Gynecology Hospital Affiliated to Fudan University were enrolled in this retrospective study. Among 184 patients were followed up, the range of following up were 12 to 21 months. 116 cases presented dysmenorrheal. Based on postoperative treatment, they were classified into 124 cases treated by domestic gonadotropin releasing hormone agonist(GnRH-a) post-operatively for 3-6 months and 60 cases without postoperative treatment. Among all, 63 patients were treated with, that was leuprorelin acetate microspheres for injection (Beiyi, 3.75 mg, q28 d), 61 patients were treated with imported GnRH-a post-operatively for 3-6 months, that were either Zoladex(3.6 mg, q28 d), Dophereline(3.75 mg, q28 d) or Enatone (3.75 mg, q28 d). The recurrence and pain improvement were compared among those groups. RESULTS: (1) The total rate of cyst recurrence was 12.5% (23/184) while the average recurrent time was (13.7 ± 2.6) months (2-21 months). The cyst recurrence rate was significantly lower in patients treated with GnRH-a post-operatively than those who didn't take medications [21.7% (13/60) versus 8.1% (10/24), P < 0.05]. However, there was no significant difference between domestic GnRH-a group and the imported one [7.9% (5/63) versus 8.2% (5/61), P > 0.05]. (2) After conservative surgery, symptoms were found to be relieved in 87.1% (101/116) patients among 116 patients complaining of dysmenorrheal pre-operatively and the pain recurrence rate was 12.9% (13/101). However, there was no significant difference in either symptom relief rate or pain recurrence rate among different groups. The symptom relief rate were 87% (33/38), 86% (37/43) and 89% (31/35) while the pain recurrence rate were 12% (4/33), 14% (5/37) and 13% (4/31) respectively in none, imported GnRH-a group and domestic GnRH-a group. CONCLUSIONS: Leuprorelin acetate microspheres could be effective in preventing recurrence of ovarian endometrioma, but not in symptom relieving after conservative surgery in short term. The effect of domestic and imported GnRH-a was similar.

p53 codon 72 polymorphism (C/G) and the risk of human papillomavirus-associated carcinomas in China.

BACKGROUND: Human papillomavirus (HPV) plays an important role in the development of carcinomas at various body sites. It was found previously that the p53 codon 72 polymorphism (C/G) is a high-risk factor for the development HPV-associated cervical carcinoma. However, it still was considered controversial in several studies of cervical and esophageal carcinoma. METHODS: In the current study, the authors used an allele specific polymerase chain reaction (PCR) method to analyze correlation between the p53 codon 72 (C/G) polymorphism and HPV-associated, noncancerous esophageal epithelium as well as esophageal, ovarian, and breast carcinoma in the Chinese population. Esophageal balloon cytology examination samples were obtained from high-incidence and low-incidence populations for esophageal carcinoma in Anyang (Henan Province). RESULTS: Thirty-six of 48 esophageal balloon samples from the high-incidence population were HPV positive, and 13 of 33 esophageal balloon samples from the low-incidence population were HPV positive. Thirty-nine of 62 esophageal carcinoma samples from Anyang Tumor Hospital were HPV positive. Twenty-six of 39 ovarian carcinoma samples from the Second Affiliated Hospital of Inner Mongolia Medical College were HPV positive. Nineteen of 82 breast carcinoma samples from Beijing Cancer Hospital were HPV positive. It is noteworthy that the distribution of the p53 codon 72 Arg homozygous genotype in HPV positive samples of esophageal epithelium, ovarian carcinoma, and breast carcinoma was significantly higher compared with HPV negative tumor samples. (P < 0.05). CONCLUSIONS: The current results suggest that the p53 codon 72 Arg homozygous genotype is one of the high-risk genetic factors for HPV-associated malignancies among the Chinese population.
