Prevalence of human papilloma virus in Oman: Genotypes 82 and 68 are dominating.

BACKGROUND: Persistent infection with high-risk (HR) HPV genotypes has been associated with cervical cancer, the third cancer affecting women in Oman with a crude incidence rate of 4.7 and mortality rate of 2.5 respectively. Other types of lower-risk (LR) HPV are associated with warts in both genders worldwide. OBJECTIVES: To assess the prevalence and genotype distribution of HPV and the risk factors among women with normal and abnormal cytology. METHODS: A cross sectional study conducted between September 2014 and April 2015. 258 cervical samples were obtained from women aged 18-68 years attending the Gynaecology Out-patient Clinic. HPV genotyping was performed using a multiplex real time-polymerase chain reaction (RT-PCR) assay. RESULTS: 22 different HPV genotypes were detected in 46 women (17.8%) and included 15 HR and 7 LR genotypes. Human immunodeficiency virus (HIV) patients (P = 0.052) and oral contraceptives users (P = 0.016) showed significant association with HPV infection. CONCLUSION: The most frequently observed HPV types were HR HPV 82 and LR HPV 54. These findings show that the predominant HPV genotypes in Oman are different from those seen in worldwide studies. This finding is important to determine the potential impact of preventive measures especially new vaccines to reduce the burden of cervical cancer.

Surgical cytoreduction for recurrent epithelial ovarian cancer.

BACKGROUND: The standard management of primary ovarian cancer is optimal cytoreductive surgery followed by platinum-based chemotherapy. Most women with primary ovarian cancer achieve remission on this combination therapy. For women achieving clinical remission after completion of initial treatment, most (60%) with advanced epithelial ovarian cancer will ultimately develop recurrent disease. However, the standard treatment of women with recurrent ovarian cancer remains poorly defined. Surgery for recurrent ovarian cancer has been suggested to be associated with increased overall survival. OBJECTIVES: To evaluate the effectiveness and safety of optimal secondary cytoreductive surgery for women with recurrent epithelial ovarian cancer. To assess the impact of various residual tumour sizes, over a range between 0 cm and 2 cm, on overall survival. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group Trials Register, MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) up to December 2012. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. For databases other than MEDLINE, the search strategy has been adapted accordingly. SELECTION CRITERIA: Retrospective data on residual disease, or data from randomised controlled trials (RCTs) or prospective/retrospective observational studies that included a multivariate analysis of 50 or more adult women with recurrent epithelial ovarian cancer, who underwent secondary cytoreductive surgery with adjuvant chemotherapy. We only included studies that defined optimal cytoreduction as surgery leading to residual tumours with a maximum diameter of any threshold up to 2 cm. DATA COLLECTION AND ANALYSIS: Two review authors (KG, TA) independently abstracted data and assessed risk of bias. Where possible the data were synthesised in a meta-analysis. MAIN RESULTS: There were no RCTs; however, we found nine non-randomised studies that reported on 1194 women with comparison of residual disease after secondary cytoreduction using a multivariate analysis that met our inclusion criteria. These retrospective and prospective studies assessed survival after secondary cytoreductive surgery in women with recurrent epithelial ovarian cancer.Meta- and single-study analyses show the prognostic importance of complete cytoreduction to microscopic disease, since overall survival was significantly prolonged in these groups of women (most studies showed a large statistically significant greater risk of death in all residual disease groups compared to microscopic disease).Recurrence-free survival was not reported in any of the studies. All of the studies included at least 50 women and used statistical adjustment for important prognostic factors. One study compared sub-optimal (> 1 cm) versus optimal (< 1 cm) cytoreduction and demonstrated benefit to achieving cytoreduction to less than 1 cm, if microscopic disease could not be achieved (hazard ratio (HR) 3.51, 95% CI 1.84 to 6.70). Similarly, one study found that women whose tumour had been cytoreduced to less than 0.5 cm had less risk of death compared to those with residual disease greater than 0.5 cm after surgery (HR not reported; P value < 0.001).There is high risk of bias due to the non-randomised nature of these studies, where, despite statistical adjustment for important prognostic factors, selection is based on retrospective achievability of cytoreduction, not an intention to treat, and so a degree of bias is inevitable.Adverse events, quality of life and cost-effectiveness were not reported in any of the studies. AUTHORS' CONCLUSIONS: In women with platinum-sensitive recurrent ovarian cancer, ability to achieve surgery with complete cytoreduction (no visible residual disease) is associated with significant improvement in overall survival. However, in the absence of RCT evidence, it is not clear whether this is solely due to surgical effect or due to tumour biology. Indirect evidence would support surgery to achieve complete cytoreduction in selected women. The risks of major surgery need to be carefully balanced against potential benefits on a case-by-case basis.

Postirradiation primary vaginal angiosarcoma with widespread intra-abdominal metastasis.

We report a primary vaginal angiosarcoma with widespread intra-abdominal metastasis occurring in a 73-yr-old woman 13 yr after vaginal brachytherapy for an endometrial carcinoma. This is an extremely rare phenomenon with only 7 previously reported cases of vaginal angiosarcoma, 5 of which were associated with earlier irradiation. All of the earlier reported cases have been localized to the pelvis without metastatic disease.
