PURPOSE: to evaluate the frequency of TP53 codon 72 polymorphism in infertile women with endometriosis, women with idiopathic infertility, controls and its relation to the disease. METHODS: a case-control study that included 198 infertile women with endometriosis, 70 women with idiopathic infertility and 169 fertile women without endometriosis as control. Detection of TP53 codon 72 gene polymorphism (rs1042522, Arg/C:Pro/G), that promotes a C/G exchange in the coding region of the gene, was performed by real time Polymerase Chain Reaction (PCR), using the TaqMan system of primers, that flank the implicated region and probes labeled with different fluorescent dyes, one for allele C and other for allele G. When two dyes were observed, the patient was considered to be heterozygous CG. In the presence of only one dye, the individual was considered to be homozygous CC or GG. The χ2 test was used to compare allele and genotype frequencies between groups. All p-values were two-tailed and a p-value <0.05 was considered to be statistically significant. RESULTS: we found no statistically significant difference in the distribution of TP53 codon 72 polymorphism genotypes CC, CG or GG (p=0.7) and alleles C or G (p=0.4) between infertile patients with endometriosis and controls (p=0.4), regardless of the stage of the disease. In relation to infertility, no statistically significant difference in the genotype or allele distribution (p=1.0 and p=0.9, respectively) was observed between idiopathic infertile women and controls. Considering the dominant inheritance model, again, no statistically significant difference was found even in the endometriosis (p=0.5) or the idiopathic infertility group (p=0.9) when compared to controls. Regarding the recessive inheritance model no statistically significant difference was found, with p=0.6 and p=1.0, respectively, for the endometriosis and idiopathic infertility groups. CONCLUSION: the results suggest that the TP53 codon 72 polymorphism does not confer genetic susceptibility to endometriosis and/or infertility in the Brazilian population, not even the severe form of the disease.

Purpose: to demonstrate a new approach to treatment of endometrial cancer. Methods: Between February, 1996 and February, 1998, twelve patients with endometrial cancer, diagnosed by hysteroscopy and biopsy, were submitted to pelvic lymphadenectomy and hysterectomy with salpingo-oophorectomy by laparoscopy. The mean age was 58.1 years, the mean number of gestations was 2.3 and the mean body mass index was 28.6. Results: the mean length of anesthesia was 4.8 hours. The mean time of hospital stay was 3.3 days. The total of lymph nodes obtained was 176, 104 (59.1%) being from the right side and 72 (40.9%) from the left side. The mean of lymph nodes per patient was 18.5. We observed two complications: in one case the laparoscopic procedure had to be abandoned because the patient presented a dangerous increase in intratracheal pressure and in the other case a granuloma in the vagina was observed. Conclusions: the initial evaluation of the laparoscopic hysterectomy and laparoscopy shows that we achieved good results regarding the accuracy of staging, the number of nodes and a small number (3) of complications.
