Objective To obtain the best cervical cancer treatment benefit through kilovoltage cone-beam CT (kV-CBCT) positioning, by using high-precision external beam therapy technology, that is, image-guided radiation therapy/volumetric modulated arc therapy (IGRT/VMAT). Methods Two hundred and five patients with cervical cancer treated with IGRT/VMAT were included in the experimental group. After kV-CBCT positioning once a week, these images were matched with the planned CT scan images and the setup errors were recorded. A total of 1 025 kV-CBCT images were studied. Ninety patients with cervical cancer positioned by conventional X-ray during the same period were selected as the control group. The boundary of the planned target volume (PTV) was calculated based on the setup errors. Results In the experimental group, the setup errors in the anteroposterior, superoinferior and mediolateral direction were (1.8±1.1) mm, (2.8±2.2) mm, and (1.7±1.4) mm, respectively. And in the control group, the setup errors were (2.8±2.1) mm, (3.9±2.2) mm, and (2.7±2.4) mm, respectively. The differences between the two groups were statistically significant (P<0.05). In the experimental group, the CTV-PTV boundaries in the anteroposterior, superoinferior and mediolateral direction were 5.27 mm, 8.54 mm, and 5.23 mm, respectively. And in the control group, the CTV-PTV boundaries were 8.47 mm, 11.29 mm, and 8.43 mm, respectively. Conclusion When using high-precision technology to treat cervical cancer, weekly kV-CBCT is a satisfactory and accurate positioning method, which helps to reduce the CTV-PTV boundary.

Objective To study the effects of two different manual reduction of geotropic nystagmus horizontal semicircular canal benign paroxysmal positional vertigo. Methods 50 cases of patients with two different groups, treated with different manual reduction. Patients with short term treatment but ineffective were treated in combination with forced prolonged lateral position FPP. Results The cure rate of initial treatment in the 360-Barbecue manual reduction groups was 80%, the Gufoni manual reduction groups was 72%.
