Initial Hyperleukocytosis and Neutrophilia in Nasopharyngeal Carcinoma: Incidence and Prognostic Impact.

ABSTRACT: BACKGROUND:This study aimed to evaluate initial hyperleukocytosis and neutrophilia as prognostic indicators in patients with nasopharyngeal carcinoma. METHODS:A retrospective analysis of 5,854 patients identified from a cohort of 6,035 patients diagnosed with nasopharyngeal carcinoma was performed with initial hyperleukocytosis and neutrophilia analyzed as prognostic factors. Multivariate Cox proportional hazards analyses were applied. RESULTS:Hyperleukocytosis was observed in 508 patients (8.7%). Multivariate analysis showed that initial hyperleukocytosis was an independent predictor of death (HR 1.40, 95%CI 1.15-1.70, p = 0.001), progression (HR 1.25, 95%CI 1.06-1.47, p = 0.007) and, marginally, distant metastasis (HR 1.21, 95%CI 0.97-1.52, p = 0.088). Neutrophilia was also an independent predictor of death (HR 1.46, 95%CI 1.18-1.81, p = 0.001), progression (HR 1.31, 95%CI 1.10-1.56, p = 0.003), and distant metastasis (HR 1.29, 95%CI 1.02-1.65, p = 0.036), after adjusting for prognostic factors and excluding hyperleukocytosis. CONCLUSION:Initial hyperleukocytosis and neutrophilia were independent, poor prognostic factors and may be convenient and useful biological markers for survival of patients with nasopharyngeal carcinoma.

Project description:BackgroundGamma-glutamyltransferase (GGT) is a membrane-bound enzyme involved in the metabolism of glutathione. Studies suggested that GGT played an important role in the tumor development, progression, invasion and drug resistance and prognosis. The association between GGT and prognosis of patients with nasopharyngeal carcinoma (NPC) was unknown. This study was conducted to investigate the association of pretherapeutic serum level of GGT with clinical-pathological parameters and survival in patients with NPC.MethodsTwo hundred and twenty-two patients with NPC were recruited in this study and were stratified into two GGT risk groups (≤ 34.5 U/L, > 34.5 U/L). The association of pretherapeutic serum GGT levels with clinical-pathological parameters was examined. Univariate and multivariate survival analyses were performed.FindingsThe pretherapeutic serum level of GGT was not associated with gender, age, pathology, T stage, N stage, TNM stage, chemotherapy or radiotherapy in patients with NPC. Patients in the high-risk GGT group had a poorer survival than the low-risk GGT group (3-year overall survival, 74.2% vs. 50.2%, P = 0.001; 3-year progression-free survival, 76.4% vs. 47.1%, P < 0.001; 3-year loco-regional relapse-free survival, 76.4% vs. 51.3%, P < 0.001; 3-year distant metastasis-free survival, 89.5% vs. 66.4%, P < 0.001). Multivariate analysis suggested that patients in the high-risk GGT group had 2.117 (95% confidence interval [CI], 1.225 ∼ 3.659, P = 0.007) times the risk of death, 2.836 (95% CI, 1.765 ∼ 4.557, P < 0.001) times the risk of progression, 2.551 (95% CI, 1.573 ∼ 4.138, P < 0.001) times the risk of relapse, and 3.331 (95% CI, 1.676 ∼ 6.622, P < 0.001) times the risk of metastasis compared with those in the low-risk GGT group.ConclusionThe pretherapeutic serum level of GGT might serve as a novel independent prognostic factor for overall-survival, progression-free survival, loco-regional relapse-free survival and distant metastasis-free survival in patients with NPC.

Project description:PurposeTo investigate prognostic impact of chemoradiotherapy-induced hemoglobin (Hb) decrease on treatment outcomes of endemic nasopharyngeal carcinoma (NPC).Materials and methodsEight hundred and fifteen non-metastatic NPC, receiving neoadjuvant chemotherapy followed by radiotherapy (NACT+RT group) or concomitant chemoradiotherapy (CCRT group), were enrolled in this study, who were regrouped according to pre-radiotherapy Hb (pre-RT Hb), post-radiotherapy Hb (post-RT Hb) and individual Hb decrease through radiotherapy or CCRT (△Hb), respectively. Survival curves were estimated using Kaplan-Meier method and compared by log-rank test. Multivariate analysis was performed using the COX proportional hazard model and binary logistic regression model.ResultsA poorer 5-year disease-free survival (DFS) was observed when pre-RT Hb<130.00 g/L. However, post-RT Hb<130.00 g/L was associated with significantly poorer 5-year locoregional recurrence-free survival (LRFS) (P=0.010) and disease specific survival (DSS) (P=0.008). Multivariate analysis with the COX proportional hazard model identified post-RT Hb<130.00 g/L as an independent negative prognostic factor for both LRFS (hazard ratio [HR], 1.896; 95% confidence interval [CI], 1.158-3.106; P=0.011) and DSS (HR, 1.767; 95% CI, 1.152-2.711; P=0.009). Similarly, △Hb <-15.00 g/L also predicted poorer 5-year LRFS (P=0.024) and DSS (P=0.015), which was confirmed in multivariate analysis as an independent adverse prognostic factor for LRFS (HR, 1.586; 95% CI, 1.058-2.377; P=0.026) and DSS (HR, 1.556; 95% CI, 1.087-2.227; P=0.016), respectively. Multivariate analysis with binary logistic regression model indicated that CCRT was a significantly independent predictor for post-RT Hb <130.00 g/L and △Hb < -15.00 g/L.ConclusionsChemoradiotherapy-induced decreased Hb levels have negative influence on locoregional control and survival, and might counteract the benefit of neoadjuvant/concomitant chemotherapy. Further studies on supportive care to maintain sufficient Hb level during chemo-radiotherapy are warranted.

Project description:PurposeTo explore the prognostic impact of combined tumor-infiltrating lymphocytes (TILs) and pretreatment peripheral lymphocyte percentage (LYM%) among patients with locally advanced nasopharyngeal carcinoma (LA-NPC).Patients and methodsTILs and pretreatment LYM% were retrospectively assessed in 253 LA-NPC patients who underwent chemoradiation therapy between January 2012 and December 2017. According to TILs and LYM% status, the patients were divided into three groups: high-risk group (HRG) (TILs-LYM% score = 0), middle-risk group (MRG) (TILs-LYM% score = 1), and low-risk group (LRG) (TILs-LYM% score = 2). The relationship between TILs level and LYM%, and also the associations of TILs-LYM% status with clinicopathological factors and survival, were evaluated.ResultsAs a continuous variable, LYM% was significantly higher in TILs-high group. High TILs or high LYM% alone was significantly related to better 3-year disease-free survival (DFS), overall survival (OS), distant metastasis-free survival (DMFS) and locoregional relapse-free survival (LRRFS), respectively. Kaplan-Meier analysis and log-rank tests also revealed significant decreases in DFS, OS, DMFS, and LRRFS among LA-NPC patients with TILs-LYM% score of 0, 1, and 2 (all P <0.05). Further multivariate analyses showed that TILs-LYM% score was an independent factor affecting survival of the patients, and HRG (TILs-LYM% score = 0) had increased hazard ratios (HRs) for disease (HR = 6.89, P <0.001), death (HR = 8.08, P = 0.008), distant metastasis (HR = 7.66, P = 0.001), and local relapse (HR = 5.18, P = 0.013) compared with LRG (TILs-LYM% score = 2). In receiver operating characteristics (ROC) analyses, TILs-LYM% score had a higher area under the ROC curve (AUC) for the prediction of DFS than did TILs or LYM% alone.ConclusionsA positive correlation was found between TILs level and pretreatment blood lymphocyte percentage. Moreover, TILs-LYM% score can be considered as a novel independent prognostic indicator of survival outcome among patients with LA-NPC.
