Abstract
Objective : To evaluate the ability of clinical impression and
ultrasound features to discriminate a benign from a malignant
ovarian mass.
Design : A prospective study.
Setting Department of Gynaecology, Hospital Tengku Ampuan
Afzan, Kuantan, Pahang.
Subjects : 126 women admitted consecutively to the gynaecology
department for surgical exploration of an ovarian mass
between 1st February 1999 and 31st January 2000. Main outcome measures : The sensitivities, specificities, positive
and negative predictive values of ultrasound features and
clinical impression for discriminating a benign from a
malignant ovarian mass.
Results : 120 constituted the study population after excluding 6
cases of non-ovarian pelvic pathology. 97 cases ( 81 o/o ) were
diagnosed as benign ovarian tumours and 23 cases ( 19°/o ) as
malignant. Clinical impression gave the highest level of
sensitivity and specificity, followed by ultrasound score of 2-5
in the discrimination between benign and malignant ovarian
masses. Both achieved sensitivity and specificity of greater
than 70o/o and showed superiority over the individual
ultrasound features suggestive of malignancy.
Conclusions : Clinical examination and ultrasound scanning are
methods which can be applied easily in our centre in the
preoperative evaluation of ovarian masses. The diagnostic
accuracy may be improved by including tumour markers or
more detailed ultrasound assessment, this would be at the
expense of simplicity and increased financial cost.
