Table 3 Cox-regression analysis of survival difference in stage III/IV OPSCC stratified based on treatment strategy, stage of cancer included as covariate

From: Primary surgery versus chemoradiotherapy for advanced oropharyngeal cancers: a longitudinal population study

    95% confidence interval
Treatment HR p value Lower Upper
S-CRT baseline baseline baseline baseline
S-RT 1.974 0.011 1.170 3.330
CRT 2.785 0.001 1.525 5.086
RT 5.398 <0.0001 3.128 9.315
  1. OPSCC – oropharyngeal squamous cell carcinoma.
  2. RT – radiotherapy.
  3. CRT- combined chemotherapy and radiation therapy.
  4. S-RT – surgical resection +/− reconstruction followed by adjuvant radiotherapy.
  5. S-CRT – surgical resection +/− reconstruction followed by combined adjuvant chemotherapy and radiotherapy.
  6. HR – hazard ratio.
