“…[15][16] A comparison of various studies has shown that that RI 0.4 and PI <1 is highly suggestive of malignancy.

So, this study is conducted to see the effectiveness of colour flow mapping and pulsed Doppler studies in determining the nature of tumour.…”

Background: Adnexal masses in perimenopausal women presents a specific diagnostic challenge because benign masses outnumbers malignant masses. Majority of adnexal masses are benign but 25% are malignant. The objective of this study was to see the effectiveness of transvaginal colour Doppler in predicting malignancy in adnexal masses in perimenopausal women.Methods: Clinically detected adnexal masses were subjected to transabdominal ultrasound scan (for basic characterization of mass into solid, cystic, mixed) then transvaginal scan and neovascularization, resistivity index (RI) was measured. Subsequently all patients underwent laparotomy. Histopathological reports obtained, and correlation done between USG and histopathology.Results: Among cystic masses neovascularization was present in 4 cases, among them benign and malignant masses were equal in number. Among mixed masses neovascularization was present in 17 cases 9 were malignant 8 benign, among solid masses all cases where neovascularization was detected were malignant. Neovascularization was absent in 12 cystic masses and 11 mixed masses, and all were benign. Kappa value calculated for tumour status and neovascularization is 0.610 which is substantially agreement with neovascularization as predictor of malignancy. Sensitivity, specificity, positive predictive value and negative predictive value of neovascularization for cystic masses are 100, 85, 50, 100(%) respectively. Sensitivity, specificity, positive predictive value and negative predictive value of neovascularization for mixed masses are 100, 57.89, 52.94, 100(%) respectively. Sensitivity and positive predictive value of neovascularization for solid masses is 100(%). Sensitivity specificity positive predictive value and negative predictive value of RI for cystic masses: 100, 92.8, 66.6, 100 (%) respectively. Sensitivity specificity positive predictive value and negative predictive value of RI for mixed masses: 77.7, 89.4, 77.7, 89.4(%). Sensitivity positive predictive value of RI for solid masses 100%.ROC curve analysis shows cut off value for differentiating between benign and malignant masses is 0.4. Less than 0.4 has more chance of malignancy.Conclusions: Transvaginal Doppler ultrasound must be done preoperatively for adnexal mass characterization.

“…A comparison of different studies have shown that resistance index less than 0.4 and pulsatility index less than 1.0 are generally considered to be suspicious for malignancy.

Objective: This prospective study was undertaken to assess the sensitivity and specificity of color flow mapping and pulse Doppler waveform in identifying malignancy preoperatively in adnexal masses in perimenopausal women. Materials and methods:A total of 100 cases with adnexal masses in perimenopausal women were scanned, underwent color flow mapping and pulsed Doppler waveform studies. These cysts were divided into three groups according to their ultrasound appearance -cystic, mixed cystic and solid. All the adnexal mases were removed surgically and sent for histopathological study. Results:The sensitivity and specificity of color flow mapping in identifying malignant ovarian tumors was 63.6 and 87.0% respectively. In the case of solid cysts, color flow mapping identified all malignant tumors. But, color flow mapping missed malignancies in cystic and mixed cystic masses. To improve detection rates, we used Doppler waveform studies and used resistance index less than 0.4 as the indicator of malignancy and found overall sensitivity and specificity of 90.9 and 92.3%, which was higher than that of color flow mapping. Conclusion:To conclude ultrasonic color flow mapping and pulse Doppler waveform studies used preoperatively on adnexal masses in perimenopausal women are widely available, performed rapidly and relatively easily, cost-effective and a reliable noninvasive method to predict malignancy preoperatively.

Die laparoskopische Therapie von Adnextumoren in der Pr-ä und Postmenopause findet immer weitere Verbreitung. Voraussetzung für ein endochirurgisches Vorgehen ist das Fehlen von Malignitätskriterien während der präoperativen Diagnostik. Der präoperative diagnostische Aufwand sollte hierbei in einem sinnvollen Verhältnis zur diagnostischen Sicherheit stehen. Im nachfolgenden Artikel wird ein präoperatives Diagnostikkonzept zur Dignitätsbeurteilung vorgestellt, welches mit einem vergleichsweise geringen Aufwand ein Maximum an diagnostischer Sicherheit bietet.
