ABSTRACT
BACKGROUND/AIM:
Diagnosis of cervical cancer with tumor diameter <2 cm using magnetic resonance imaging alone has not been investigated. Moreover, whether tumor volume can be used for diagnosing the true tumor diameter remains unknown. Here, we investigated the utility of early cervical cancer volume index in diagnosing cervical cancer with a tumor diameter of <2 cm, which can be treated using more conservative surgery. PATIENTS ANDMETHODS:
This single-center retrospective study analyzed women who underwent radical hysterectomy for cervical cancer with a tumor diameter of <2 cm and clinical stages IA2, IB1, IB2, IB3, and IIA1 at our institute between January 2009 and April 2022. The volume index, defined as the product of the maximum longitudinal diameter along the uterine axis, maximum anteroposterior diameter (thickness) on a sagittal section image, and maximum horizontal diameter on a horizontal section image, was evaluated using either T2-weighted magnetic resonance imaging or gadolinium-enhanced T1-weighted imaging. The receiver operating characteristic curve for the volume index was also calculated.RESULTS:
The sensitivity and specificity of magnetic resonance imaging for measuring the tumor diameter were 0.92 and 0.84, respectively. The calculated cut-off value was 2.60, whereas the volume index area under the curve was 0.955, with a sensitivity of 0.92 and specificity of 0.93.CONCLUSION:
Considering the specificity and low incidence of false-negative results, the volume index can be used for preoperative diagnosis of pT1B1 cervical cancer, which can be treated with more conservative surgery.Palabras clave
