Purpose The purpose of this study was to describe an approach to cervical brachytherapy for a patient with a complete bicorporeal uterus and locally advanced cervical cancer (LACC). Materials and methods The patient was a 53-year-old woman with a complete bicorporeal uterus, diagnosed with stage IIB cervical squamous cell carcinoma due to contact bleeding. The patient underwent concurrent chemoradiotherapy (CCRT), external beam pelvic radiotherapy with 45 Gy/25 fractions, and weekly cisplatin (40 mg/m 2 ). Brachytherapy was administered following the completion of external beam radiotherapy. Results The brachytherapy, which was CT (Computed Tomography)-guided using two CT-compatible tandems and two CT-compatible ovoids, delivered a prescription dose of HRCTV D90 was 6 Gy*5F, which achieved satisfactory dose coverage. The patient’s final HRCTV D90 EQD2 10 was 84.9 Gy, and IRCTV D90 EQD2 10 was 63.5 Gy. Rectum D2cc EQD2 3 was 66.03 Gy, bladder D2cc EQD2 3 was 75.57 Gy, sigmoid D2cc EQD2 3 was 63.93 Gy, and intestine D2cc EQD2 3 was 65.86 Gy. Follow-up at 1 year was CR. Conclusions For patients with cervical cancer and a complete bicorporeal uterus, using double tandems combined with double ovoids is a feasible treatment method to ensure adequate dose coverage without causing additional damage. This method is also applicable to patients with endometrial cancer.
