RESUMEN
Human papillomavirus [HPV] has also been suggested as an etiology of esophageal squamous cell carcinoma [SCC]. The aim of this study was to investigate the prevalence of HPV infection in esophageal SCCs in our region with strict contamination control to prevent false positive results. Thirty cases of esophageal squamous cell carcinomas were chosen by simple random selection in a period of two years. PCR for target sequence of HPV L1 gene was performed on nucleic acid extracted from samples by means of GP5+/GP6+ primers. All tissue samples in both case and control groups were negative for HPV-DNA. Although the number of cases in this study was limited, the contribution of HPV in the substantial number of esophageal SCCs in our region is unlikely

RESUMEN
To report a case of long-term disease free and successful pregnancy after fertility sparing staging surgery with adjuvant chemotherapy in a 46,Xy gonadal dysgenetic with malignant germ cell tumor. A case report from a university hospital about a 19-year-old female with 46,XY karyotype [Swyer syndrome]. The patient underwent bilateral gonadectomy and staging with uterus preservation. Six course adjuvant chemotherapy with VBP [Vinblastin, Bleomycin, Cisplatin] was given. The case got pregnant through IVF- embryo donation. Disease free period and successful pregnancy is reported. After treatment the patient is free of the disease after 11 years follow-up. She underwent in vitro fertilization treatment with oocyte donation and gave birth to a healthy ch. Improved multimodality treatment, allowance for consideration of fertility options for some women with gynecologic cancers. Since major concern in women with XY gonadal dysgenesis is ovarian malignancy, even with stage II dysgerminoma hysterectomy may not be required in some cases considering the opportunity for childbearing with the use of embryo transfer
