RESUMEN
BACKGROUND: Non-random simple chromosomal aberrations in various malignancies provide important insights into the molecular pathogenesis of human cancer. Although extensive data exist on recurring chromosomal abnormalities in hematological cancer, data on individual solid tumor types remain limited. Here we present the case of a patient with ovarian cancer with a specific chromosomal abnormality. CASE REPORT: Cytogenetic analysis utilized a G-banding technique, which was performed with direct culture of the surgically removed cancer cells from a 23-year-old woman with grade II ovarian serous cystadenocarcinoma. The patient had no family history of ovarian cancer. RESULTS: We report a novel der(16)t(3;16)(p25;q24) accompanied by terminal deletion of 3p25 as the simple chromosomal aberration in this case. CONCLUSION: To the best of our knowledge, no such translocation has been previously reported. The present study supports the possible role of both del(3)(p25) and the translocation t(3;16)(p25;q24) in ovarian cancer; nevertheless, the significance of these chromosomal changes in the development of ovarian cancer remains unknown. The significance of this finding and its role in the pathogenesis of ovarian cancer requires further clarification.

Infertile women with chronic anovulation are prone to be exposed to unopposed estrogen stimulation and have the high risk of being suffering from endometrial hyperplasia or even endometrial carcinoma. A few reports have suggested that nulliparous young women (under 40 yr of age) with endometrial carcinoma could be treated conservatively to preserve fertility and succeed the live birth. We report on a 36-yr-old woman who received conservative treatment of endometrial carcinoma (stage I, grade 1) by curettage and progestin. After megestrol medication of total 71,680 mg during 24 weeks, we found the regression of endometrial lesion by curettage and hysteroscopic examination. Then we decided to perform in vitro fertilization program. Two embryos were transferred and heterotypic pregnancy was diagnosed 27 days after embryo transfer. After right salpingectomy, she received routine obstetrical care and delivered by cesarean section at 38 weeks in gestational periods. Two years after delivery, she is healthy without any evidence of recurrent disease. The fertility preserving treatment is an option in endometrial cancer patients if carefully selected, and assisted reproductive technologies would be helpful.
