From: Pretreatment platelet count improves the prognostic performance of the TNM staging system and aids in planning therapeutic regimens for nasopharyngeal carcinoma: a single-institutional study of 2,626 patients

Figure 2

Survival analysis based on pretreatment platelet count (≤300 × 10 9 /L and >300 × 10 9 /L) in all 2,626 patients with nasopharyngeal carcinoma stratified by T category/N category/TNM classification. A, overall survival curves for the 4 groups stratified by T category. B, distant metastasis–free survival curves for the 4 groups stratified by T category. C, overall survival curves for the 4 groups stratified by N category. D, distant metastasis–free survival curves for the 4 groups stratified by N category. E, overall survival curves for the 4 groups stratified by TNM classification. F, distant metastasis–free survival curves for the 4 groups stratified by TNM classification. Group 1: T1–2/N0/stages I–II disease with platelet count ≤300 × 109/L; Group 2: T1–2/N0/stages I–II disease with platelet count >300 × 109/L; Group 3: T3–4/N1–3/stages III–IV disease with platelet count ≤300 × 109/L; Group 4: T3–4/N1–3/stages III–IV disease with platelet count >300 × 109/L.
