Bottom Line: We present a case of cervical cancer treated by concurrent chemoradiation.In radiation therapy part, the combination of the whole pelvic helical tomotherapy plus image-guided brachytherapy with megavoltage computed tomography of helical tomotherapy was performed.We propose this therapeutic approach could be considered in a curative setting in some problematic situation as our institution.

Figure 2: Megavoltage computed tomography of tomotherapy with the planning to the dose of 46 Gy/23 fractions (blue color) in (A) transverse, (B) coronal, and (C) sagittal views.

Mentions: For whole pelvic helical tomotherapy (WPHT), the simulation by CT was performed at the outsource department with 5-mm slice thickness. Clinical target volume (CTV) composed of gross tumor volume, cervix, uterus, parametrium, adnexae, and elective pelvic lymph nodes (common iliac, external iliac, internal iliac and presacral lymph nodes) were contoured as the Radiation Therapy Oncology Group (RTOG) guidelines. The normal tissues (organs at risk [OARs]; bladder, rectum, sigmoid, bowels, and head of femurs) were also contoured. WPHT was done to the dose of 46 Gy in 23 fractions according to ICRU Report 83 (Fig. 2). The dose at 98% of reference volume (D98%) of CTV, D2% of the bladder, D2% of rectum, and D2% of sigmoid colon were recorded [2]. Weekly cisplatin (40 mg/m2) was prescribed to the patient with the total of five cycles. The MVCT was performed everyday to check the position before irradiation.
