Clinical and ultrasound characteristics of vaginal lesions.

OBJECTIVE: Ultrasound examination represents the most important diagnostic method to preoperatively assess gynecological diseases. However, the ultrasound characteristics of vaginal pathologies are poorly investigated. The aim of this study was to describe the clinical and ultrasound characteristics of vaginal lesions detected at ultrasound. METHODS: This was a single center, prospective, observational study including patients with vaginal masses examined from January 2017 to May 2019. Morphologic sonographic characteristics of the lesions were described as unilocular, multilocular, unilocular-solid, multilocular-solid, and solid. For the analysis, patients were grouped into a 'malignant group', including patients with confirmed malignancy at final histology, and a 'benign group', including patients with a confirmed benign pathology at final histology and patients without a histological diagnosis but with a lesion that manifested no changes during follow-up. RESULTS: 44 patients were enrolled. 22 (50%) of 44 lesions were benign: 12 (54.5%) of these underwent ultrasound follow-up and did not show any changes at the 12 month follow-up whereas 10 (45.5%) lesions had surgical excision which confirmed the benign nature. The remaining 22 (50%) of 44 lesions underwent surgery because of suspicion of malignancy: histology confirmed a malignancy in 20 (90.9%) of 22 cases. Benign lesions were described as follow: 11/24 (45.8%) unilocular, 3/24 (12.5%) multilocular with two locules, and 10/24 (41.7%) solid lesions. Malignant lesions were solid in 19/20 (95%) cases and multilocular-solid in 1/20 (5%). Most benign lesions had a color score of 1-2 (20/24, 83.4%) while malignant lesions had a color score of 3-4 (18/20, 90%). CONCLUSION: A typical ultrasound image of a benign lesion was a unilocular cyst or hypoechoic solid mass with no or minimal vascularization on color Doppler examination. Malignant vaginal lesions were hypoechoic solid tumors with irregular margins and moderate/rich vascularization or multilocular-solid. Ultrasound should be used to supplement the clinician in the management of vaginal lesions.

Time trade-off procedure for measuring health utilities loss with human papillomavirus-induced diseases: a multicenter, retrospective, observational pilot study in Italy.

BACKGROUND: The economic evaluation of any human papillomavirus (HPV) vaccination strategy requires the measurement of clinical benefits (quality-adjusted life-years [QALY]) gained to reflect both the increase in life expectancy and the economic benefits associated with an effective intervention. OBJECTIVE: The purpose of this pilot study was to investigate the feasibility of a standardized time trade-off (TTO) procedure to quantify utilities loss in health states affected by HPV-induced pathologies in Italy. METHODS: This multicenter, retrospective, observational, cross-sectional study was designed to elicit data on utilities in a cohort of women with a histologically confirmed diagnosis of high-grade cervical intraepithelial neoplasias (CIN2-3). An algorithm for the computerized administration of a TTO questionnaire was developed for the standardized elicitation of data on health utilities in CIN2-3, anogenital warts, and invasive cervical cancer. The European Quality of Life-5 Dimensions (EQ-5D) questionnaire was used to assess the respondents' baseline perception of their health conditions. The correlation between utilities and age, time from conization to questionnaire administration, and EQ-5D score, was tested using the Spearman rank correlation coefficient (ρ) as a measure of validity. RESULTS: Of 42 enrolled patients, 36 responded (85.7%) (mean [SD] age, 37.2 [9.0] years). The women's perception of their health state was high (mean [SD] EQ-5D score, 0.93 [0.10]). The mean utility values were 0.73 (0.22), 0.71 (0.35), and 0.02 (0.08) for CIN2-3, anogenital warts, and invasive cervical cancer, respectively. Based on ρ values, none of the 3 HPV-induced pathologies considered was significantly correlated with utility. Nonsignificant variability was found among utilities elicited for anogenital warts (range, 0.54 [0.47] to 0.79 [0.27]); this variability was a limitation of this pilot study and was likely the result of the limited sample size. CONCLUSIONS: Based on the findings from this pilot study, a TTO standardized procedure is expected to be feasible and appropriate for assessing utilities in patients affected by HPV-related diseases and for cost-effectiveness analyses of cervical cancer prevention in Italy.
