“…However, while the use abdominal ultrasound-guided insertion has been reported in many cases recently [10,11], there are a lack of data regarding the safety and efficacy of transrectal methods. Abdominal ultrasound-guided needle insertion is susceptible to hindrance caused by factors such as intestinal gas, obesity, and posture, and images may be not clear enough for clinical use [12,13]. However, while transrectal ultrasound provides clearer images of the structure of the uterus and surrounding tissues and guides insertion of the needle, there are few reports in the literature on the accuracy of this process.…”

Purpose: To investigate the role of transrectal ultrasound guidance in interstitial brachytherapy for cervical cancer. Material and methods: Forty-eight patients who underwent interstitial brachytherapy treatment for cervical cancer between January 2017 and January 2018 were enrolled in the study. The distances between each inserted needle and the lesion were measured at seven sites by ultrasound (D1-D7) and compared to the corresponding distances (M1-M7) when visualised with nuclear magnetic resonance imaging (MRI). Measurements were paired on the basis of the observation sites, e.g. D1 and M1, D2 and M2. The statistical differences, intraclass correlation coefficients (ICCs), and linear relationships for the paired measurements were calculated. Results: No significant differences were found between the paired M and D measurements, with all ICCs showing high levels of concordance (0.81-0.93). Conclusions: Transrectal ultrasound showed strong agreement with MRI results in determining the position of the inserted needles. Transrectal ultrasound is a useful tool for guided interstitial brachytherapy and is appropriate for widespread use in the treatment of locally advanced cervical cancer.

“…From our experiences, TAUS-guided brachytherapy improved the dose to the normal tissues. It reduced the cumulative overdose to the bladder (>80 Gy) and rectum (>75 Gy) in comparison to standard point A treatment and our intermediate-term results showed the 2-year local control of 88% [45]. From 2012 to 2018, more than 100 patients were treated with this technique.…”

Nowadays, brachytherapy is one of the major components to treat inoperable cervical cancer. Brachytherapy yields a higher dose to the target (cervix) while sparing normal tissues. Developments of brachytherapy stepped forward in the previous decade by image-guided brachytherapy (IGBT) turning brachytherapy from point-based planning to volume-based planning and IGBT improves the treatment quality for cervical cancer. Magnetic resonance imaging (MRI) or computed tomography (CT) is utilized in brachytherapy and showed promising results internationally. However, in a limited-resource area, the implementation of IGABT is difficult due to many causes (manpower, equipment, or budgets). To improve the quality in limited resources, ultrasound is introduced. The utilization of ultrasound in brachytherapy practice is to prevent uterine perforation during application. With present data, measurement by ultrasound showed the correlation to MRI measurement in uterine dimensions. With these aspects, there are many researches using ultrasound to improve the quality of treatment in brachytherapy, for example, to guide contouring on CT or to support brachytherapy planning. The use of ultrasound improves the quality of brachytherapy in comparison to conventional planning and supports the improvement in brachytherapy for cervical cancer.

“…Clinical outcomes achieved with ultrasound-guided planning at the Peter MacCallum Cancer Centre compare well with other image-guided protocols (see Table 1) [19,24e36]. Tharavichitkul et al [36] have also published clinical outcomes based on ultrasound planning with similar local control. The results of the international EMBRACE 1 study have recently been presented and indicate further improvements in local control, cancer-specific survival and overall survival [35].…”
