A cross sectional study of HPV type prevalence according to age and cytology.

BACKGROUND: A cross sectional study to investigate HPV prevalence according to age and cytology. METHODS: Women presenting to a gynaecological outpatient clinic for a Pap smear test were included in the study (n=3177). All women had cervical cytology and HPV testing. RESULTS: Overall prevalence of any 24 HPV type analysed was 33.1% (95% CI 31.5% to 34.7%) and HPV 16 and HPV 42 were the most frequent (6.7% (95% CI 5.8% to 7.6%), 6.8% (95% CI 5.9% to 7.6%)), in total samples. Multiple HPV infection rate was 12.9% (95% CI 11.8% to 14.1%). High risk HPV (hrHPV) types were present in 27.4% (95% CI 25.8% to 28.9%) of the samples.HPV prevalence was highest among 14 to 19 y.o (46.6% (95% CI 40.7%-52.4%)) and second highest among 30-34 y.o. (39.7%, 95% CI 35.4%-44%). HPV 16 was highest among 20-24 (9.0% (95% CI 6.4%-11.6%)) and second highest among 50 to 54 y.o. (6.3% (95% CI 2.9% to 9.8%).In Low-grade Squamous Intraepithelial Lesions (LgSIL) cytology samples, the most frequently detected hrHPV types were: 16 (14.5% (95% CI 12.1% to 16.9%)), 51 (13.0% (95% CI 10.7% to 15.3%)) and 53 (9.1% (95% CI 7.2% to 11.1%)) and in High-grade Squamous Intraepithelial Lesions (HgSIL) were: HPV 16 (37.2% (95% CI 26.5% to 47.9%)), HPV 51 (17.9% (95% CI 9.4% to 26.5%)) and HPV 18 (12.8% (95% CI 5.4% to 20.2%)). CONCLUSIONS: In the population studied, HPV 16 and 51 were the most frequent detected hrHPV types. HPV positivity, hrHPV and multiple HPV types infections were higher in young women, while HPV prevalence declined with increasing age and presented two peaks a higher (14-19 y.o.) and a lower one (30-34 y.o.) These results may contribute to the creation of a national screening programme.

Primary and metastatic ovarian cancer in patients with prior breast carcinoma. Pre-operative markers and treatment results.

BACKGROUND: The pre-operative diagnosis of primary and metastatic malignant ovarian tumors in patients treated for breast cancer is difficult. The objective of this study was to analyze and compare the characteristics and outcome of women with a history of breast cancer in order to identify pre-operative markers useful in differential diagnosis and the role of surgery in their management. MATERIALS AND METHODS: The medical records of 36 patients with a history of breast cancer, who had been operated on either for primary or metastatic cancer between 1987 and 2003, were reviewed retrospectively. RESULTS: Twenty-seven patients had been diagnosed with primary epithelial ovarian cancer (POC) and nine had metastatic disease (MOC), resulting in a 3:1 ratio. The median age of breast and ovarian cancer diagnosis was 45 and 56 years, respectively, and the median interval was 8 years. The serum CA 125 level was elevated in the majority of cases, in 70% of the POC group and 56% of the MOC, but the median level was higher, though not statistically significant, in the former. Serum CA 15-3 levels were elevated >100 U/ml in 89% of patients with MOC (p = 0.0002). BrCA mutation risk, as calculated with the BRCAPRO software program, was 41.8% and 9% in primary and metastatic tumors, respectively (p=0.0477). Ovarian spread was not the only site of metastatic breast cancer in 55.5% of the MOC group, compared to 11% of the POC patients Disease was disseminated in the abdominal cavity at the time of diagnosis in both groups, however, 78% of patients had unilateral tumors in the POC group and bilateral disease in the MOC (p=0.0133). Cytoreduction to less than 2 cm tumor diameter was feasible in 67% of primary and 44% of metastatic neoplasms. In the follow-up period (12-204 months), the median survival was 10 months for patients with metastatic disease, compared to 33 months for those with primary tumors (p<0.05). CONCLUSION: Small bilateral ovarian enlargements and minor serum elevation of CA 125 titers in patients with initial Stage IV breast cancer, suffering from multiple metastatic disease, are likely to illustrate MOC. Unilateral ovarian mass and high serum levels of CA 125 in apparently disease-free patients with a positive family history and high prevelance of BRCA mutations are suggestive of primary tumors. Optimal cytoreduction was feasible in both groups, but survival was longer in patients with primary tumors (p<0.05).

Solitary parenchymal splenic recurrence of ovarian adenocarcinoma: a case report and review of the literature.

We report a rare case of solitary parenchymal splenic recurrence of epithelial ovarian cancer which developed 27 months after the initial treatment. The patient, a 53-year-old woman, with a history of breast cancer, underwent total abdominal hysterectomy bilateral salpingo-ophorectomy (TAH & BSO), omentectomy and pelvic lymph node sampling for a serous carcinoma of the ovaries (stage IIIB). She subsequently received 6 cycles of cisplatinum chemotherapy. During follow-up, rising CA 125 serum levels heralded the 6 x 6 cm parenchymal splenic lesion which was documented by CT scan. She underwent splenectomy after pneumococcal vaccination, sandostatin and chemoprophylaxis. Histopathological evaluation revealed metastatic parenchymal disease consistent with recurrent ovarian cancer. She remains alive and disease-free for 20 months since the last operation. Isolated parenchymal splenic lesions are very rare and may occur as a late recurrence in epithelial ovarian cancer. Splenectomy can be performed with acceptable morbidity and confers a substantial survival benefit to patients.

Human papillomavirus genotyping and e6/e7 mRNA expression in greek women with intraepithelial neoplasia and squamous cell carcinoma of the vagina and vulva.

A large proportion of vaginal and vulvar squamous cell carcinomas (SCCs) and intraepithelial neoplasias (VAIN and VIN) are associated with HPV infection, mainly type 16. The purpose of this study was to identify HPV genotypes, as well as E6/E7 mRNA expression of high-risk HPVs (16, 18, 31, 33, and 45) in 56 histology samples of VAIN, VIN, vaginal, and vulvar SCCs. HPV was identified in 56% of VAIN and 50% of vaginal SCCs, 71.4% of VIN and 50% of vulvar SCCs. E6/E7 mRNA expression was found in one-third of VAIN and in all vaginal SCCs, 42.9% of VIN and 83.3% of vulvar SCCs. Our data indicated that HPV 16 was the commonest genotype identified in VAIN and VIN and the only genotype found in SCCs of the vagina and vulva. These findings may suggest, in accordance with other studies, that mRNA assay might be useful in triaging lesions with increased risk of progression to cancer.

Prevalence of human papillomavirus types 6, 11, 16, 18, 31, and 33 in a cohort of Greek women.

To study HPV prevalence and HPV types 6, 11, 16, 18, 31, and 33 distribution in cervical smears in a cohort of Greek women. One thousand six hundred thirty-six samples were cytologically evaluated and molecularly analyzed, by PCR based assay. Abnormal cytology was identified in 997 women and 75.4% of them were HPV DNA positive, while 639 had normal cytology and 24.6% were HPV DNA positive. HPV was detected in 62.9% of 256 ASCUS smears, 89.3% of 516 LSIL, 86.7% of 60 HSIL and 47.3% of 165 with cervical carcinoma. Overall, HPV 11 was the most common type (13.4%), followed by 18 (10.3%), 6 (7.2%), 16 (6.4%), 31 (3.4%) and 33 (3.4%). Multiple infections with two (11.3%) or more types, primarily 11 and 18 (4.8%), were also identified. Low-risk types 11 and 6 were common in ASCUS (36.6% and 26.4%, respectively), and high-risk types 16 and 18 in HSIL (42.3% and 30.8%, respectively) and in cancer (51.3% and 41%, respectively). Multiple infections were detected in 2.2% of normal and 31.7% of HSIL. HPV prevalence was 75.4% in abnormal and 24.6% in normal cervical smears. HPV 16 and 18 were the most common types in cancer. Single infection with type 11 and multiple infections with 11 and 18 were more frequent.
