NCT02440191

Brief Summary

It has been not clinically determined whether TomoDirect was dosimetrically better than 3D-CRT for Asian patients with early breast cancer. Therefore, the objective of this study was to compare dosimetric parameters of TomoDirect and 3D-CRT in early breast cancer patients of an Asian cohort.

Outcome Measures

Primary Outcomes (1)

  • Disease-free survival

    3-year

Secondary Outcomes (1)

  • Toxicity

    acute (time frame: with 3 months after radiation) and late (time frame: up to 3 years after radiation), Participants will be followed for an expected average of 3 years.

Study Arms (2)

3DCRT

ACTIVE COMPARATOR

conventional 3-dimensional conformal radiotherapy on the breast, 50.4 Gy/28 fx and tumor bed boost, 9 Gy/5 fx will be irradiated for 6.5 weeks.

Radiation: 3DCRT

IMRT (Intensity modulated radiotherapy)

EXPERIMENTAL

Intensity-modulated radiotherapy (IMRT) with simultaneous integrated boost (SIB) on the whole breast, 50.4 Gy/28 fx and tumor bed, 57.4 Gy/28 fx will be irradiated for 5.5 weeks. Unlike 3DCRT, concomittant boost technique is used in the IMRT arm.

Radiation: 3DCRT
