Whether Primary Bone-Only Oligometastatic Nasopharyngeal Carcinoma Patients Benefit From Radiotherapy to the Bones on the Basis of Palliative Chemotherapy Plus Locoregional Radiotherapy?-A Large-Cohort Retrospective Study.

As shown in Figure 2A,B , patients who received LRRT with or without bRT had statistically superior OS and PFS (OS: HR = 0.49, 95% CI: 0.30–0.79, p = 0.003; PFS: HR = 0.57, 95% CI: 0.41–0.80, p = 0.001) compared to patients who received PCT alone, but the addition of bRT to LRRT improved the OS and PFS compared to that of patients who received PCT + LRRT only with borderline significance (OS: HR = 0.59, 95% CI: 0.34–1.00, p = 0.051; PFS: HR = 0.72, 95% CI: 0.51–1.03, p = 0.068; Figure 2C,D ).
