Would you offer partial breast radiation to a women who otherwise meets suitability criteria but is not going to receive endocrine therapy?

What radiation option do you recommend in elderly women with small ER+ tumors s/p lumpectomy who will not undergo endocrine therapy?

• I still offer omission of RT as some women did not complete endocrine tx on CALBG 9343
• I recommend partial breast radiation
• I recommend whole breast radiation
• Other
