    High Measures of Pre-Chemoradiotherapy Platelet-to-Albumin Ratio Indicates Poor Prognosis in Locally Advanced Pancreatic Cancer Patients
    (2022) Kucuk, Ahmet; Topkan, Erkan; Selek, Ugur; Haksoyler, Veysel; Mertsoylu, Huseyin; Besen, Ali Ayberk; Pehlivan, Berrin; https://orcid.org/0000-0001-8120-7123; 35444422; AAG-2213-2021
    Purpose: In a lack of similar research, we meant to retrospectively investigate the prognostic significance of pre-chemoradiotherapy (C-CRT) platelet-to-albumin ratio (PAR) on the survival results of locally advanced unresectable pancreatic adenocarcinoma (LAPC) patients. Patients and Methods: The present analysis included 139 LAPC patients who received C-CRT in total. The utility of pre-C-CRT cutoff(s) reshaping survival data was explored using receiver operating characteristic (ROC) curve analysis. The primary and secondary objectives were the associations between PAR levels and overall survival (OS) and progression-free survival (PFS) outcomes. Results: At a median follow-up of 15.7 months (95% CI: 11.6-19.8), the overall cohort's median and 5-year OS rates were 14.4 months (95% CI: 11.8-17) and 14.7%, respectively, while the corresponding PFS rates were 7.8 months (95% CI: 6.5-9.1) and 11.2%. Because the ROC curve analysis found 4.9 as the optimal PAR cutoff for both OS and PFS [area under the curve (AUC): 75.4%; sensitivity: 72.4%; specificity: 70.3%], we divided the patients into two PAR cohorts: PAR<4.9 (N=60) and PAR>4.9 (N=79). Comparative analysis per PAR group exhibited significantly worse OS (11.2 vs 18.6 months, and 9.8% vs 20.9% at 5 years, P=0.003) and DFS (7 vs 14.3 months, and 7.6% vs 16.2% at 5 years, P=0.001) with PAR>4.9 versus PAR<4.9, respectively. In multivariate analysis, the N0 nodal status, CA 19-9 <= 90 U/mL, and PAR<4.9 were found to be independent predictors of improved OS and PFS. Conclusion: The pre-C-CRT high PAR (>4.9) robustly and independently prognosticated significantly worse OS and PFS results in inoperable LAPC patients who underwent definitive C-CRT.

    Prechemoradiotherapy Systemic Inflammation Response Index Stratifies Stage IIIB/C Non-Small-Cell Lung Cancer Patients into Three Prognostic Groups: A Propensity Score-Matching Analysis
    (2021) Topkan, Erkan; Selek, Ugur; Kucuk, Ahmet; Haksoyler, Veysel; Ozdemir, Yurday; Sezen, Duygu; Mertsoylu, Huseyin; Besen, Ali Ayberk; Bolukbasi, Yasemin; Ozyilkan, Ozgur; Pehlivan, Berrin; 0000-0001-8120-7123; 0000-0002-2218-2074; 0000-0002-7862-0192; 33552158; AAG-2213-2021; AAG-5629-2021; AAD-6910-2021
    Purpose. We explored the prognostic influence of the systemic inflammation response index (SIRI) on the survival outcomes of stage IIIB/C non-small-cell lung cancer (NSCLC) patients who underwent concurrent chemoradiotherapy. Methods. Present propensity score-matching (PSM) analysis comprised 876 stage IIIB/C NSCLC patients who received 1-3 cycles of platinum-based doublets concurrent with thoracic radiotherapy from 2007 to 2017. The primary and secondary objectives were the relationships between the SIRI values and overall (OS) and progression-free survival, respectively. Propensity scores were calculated for SIRI groups to adjust for confounders and to facilitate well-balanced comparability between the SIRI groups by creating 1 : 1 matched study groups. Results. The receiver operating characteristic curve analysis identified an optimal SIRI cutoff at 1.9 for OS (AUC: 78.8%; sensitivity: 73.7%; specificity: 70.7%) and PFS (AUC: 80.5%; sensitivity: 75.8%; specificity: 72.9%) and we grouped the patients into two PSM cohorts: SIRI < 1.9 (N = 304) and SIRI >= 1.9 (N = 304), respectively. The SIRI >= 1.9 cohort had significantly worse median OS (P<0.001) and PFS (P<0.001) than their SIRI < 1.9 companions. The further combination of SIRI with disease stage exhibited that the SIRI-1 (IIIB and SIRI < 1.9) and SIRI-3 (IIIC and SIRI >= 1.9) cohorts had the best and worst outcomes, respectively, with SIRI-2 cohort (IIIB and SIRI >= 1.9 or IIIC and SIRI < 1.9) being remained in between (P<0.001 for OS and PFS, separately). In multivariate analysis, the two- and three-laddered stratifications per the 1.9 cutoffs and SIRI groups retained their independent significance, individually. Conclusions. The SIRI >= 1.9 independently prognosticated significantly worse OS and PFS results and plated the stage IIIB/C patients into three fundamentally distinct prognostic groups.

    (2021) Abali, Huseyin; Yalcin, Suayib; Onal, Huseyin C; Dane, Faysal; Oksuzoglu, Berna; Ozdemir, Nuriye; Mertsoylu, Huseyin; Artac, Mehmet; Camci, Celaletdin; Karabulut, Bulent; Basal, Fatma B.; Budakoglu, Burcin; Sendur, Mehmet A. N.; Goktas, Burce; Ozdener, Fatih; Baygul, Arzu; 33979100
    Background: Trastuzumab prolonged the overall survival in patients with advanced gastric cancer with human epidermal growth factor receptor 2 (HER2) overexpression in combination with chemotherapy. In this phase II open-label prospective study, the tolerability and safety of trastuzumab with chemotherapy, and chemoradiotherapy for curatively resected patients with HER2-positive gastric carcinoma was investigated. Methods: The patients with HER2-positive gastric, or gastroesophageal junction adenocarcinoma, after gastrectomy plus D2 dissection, were included. They received 3 cycles of oxaliplatin (100 mg/m(2) intravenously day 1) plus capecitabine (850 mg/m(2) orally days 1 to 14), trastuzumab (8 mg/kg intravenously day 1 in cycle 1, 6 mg/kg thereafter) every 21 days, followed by chemoradiotherapy. Trastuzumab was given for 1 year. Results: Of the 212 patients screened, 35 were eligible, and 34 were treated. The median age was 56 years (minimum to maximum: 35 to 75 y), male patients constituted 73.5% (n=25), and 33 (97.1%) had gastric adenocarcinoma. R0 resection was performed in 30 (88.2%). The majority (26, 61.7%) were in stage III disease. Most of the adverse events were grade I/II, the most frequent grade III side effects were nausea (3, 8.8%), vomiting (3, 8.8%), diarrhea (2, 5.9%), and weight loss (n=2, 5.9%). Two patients died during the first 3 cycles of chemotherapy and chemoradiotherapy; 1 secondary to pulmonary thromboembolism, and the other due to cerebral ischemia. After excluding 2 with early progression and 1 consent withdrawal, of the remaining 31 patients, 28 (90.3%) were able to complete the chemotherapy and chemoradiotherapy part of the trial. After the 25 months follow-up period, 21 patients (61.8%) were alive. Overall survival at 12 and 24 months was 75.0% and 58.0%, while disease-free survival at 12 and 24 months was 65.7% and 55.0%, respectively. Conclusions: Trastuzumab in combination with capecitabine, oxaliplatin following chemoradiotherapy as the adjuvant therapy for gastric or gastroesophageal junction adenocarcinoma was considered as safe and tolerable. The frequency of HER2 overexpression in curatively resected patients is comparable to that in patients with metastatic disease

    (2020) Ozdemir, Yurday; Topkan, Erkan; Mertsoylu, Huseyin; Selek, Ugur; 0000-0002-1932-9784; 0000-0001-8120-7123; 0000-0002-2218-2074; 32214853; M-9530-2014; AAG-2213-2021; AAG-5629-2021
    Purpose: To investigate the prognostic utility of the prognostic nutritional index (PNI) in stage IIIB non-small-cell lung carcinoma (NSCLC) patients undergoing concurrent chemoradiotherapy (CRT). Methods: A total of 358 stage IIIB NSCLC patients who received a total dose of 60-66 Gy (2 Gy/fraction) radiotherapy and >= 1 cycle(s) of platinum-based chemotherapy were analyzed. The receiver operating curve analysis was utilized to identify the optimal PNI cut-off value demonstrating a significant connection with the overall survival (OS), locoregional progression-free survival (LRPFS), and progression-free survival (PFS). Results: At a median follow-up time of 22.5 months (range: 2.4-123.5), 30.2% and 14% of the patients were still alive and free of disease progression, respectively.The median OS, LRPFS, and PFS were 25.2 [95% confidence interval (CI): 36.3-46.6 months], 15.4 (95% CI: 26.6-35.3 months), and 10.7 (95% CI: 36.8-69.9 months), individually, for the whole study accomplice. The ROC analysis revealed an optimum rounded cut-off that associated meaningfully with each of the OS [area under the curve (AUC): 84.1%; sensitivity: 75.9%;72.4% specificity], LRPFS (AUC: 92.4%; sensitivity: 87.9%; 85.1% specificity), and PFS (AUC: 80.1%; sensitivity: 73.7%; 71.6% specificity) at a value of 40.5. Comparative analyses revealed that the patients presenting with PNI <= 40.5 had significantly inferior OS (16.8 vs 36.7; P<0.001), LRPFS (11.5 vs 19.5; P<0.001), and PFS (8.6 vs 13.6; P<0.001) outcomes compared to patients with PNI>40.5. In univariate analyses, lower T-stage (1-2 vs 3-4; P< 0.001), lower N-stage (N2 vs N3; P< 0.001), anemia status (absent vs present; P< 0.001), weight loss status (<5% vs >= 5%; P< 0.001), and PM group (<= 40.5 vs >40.5; P<0.001) were the factors found to be associated with OS, LRPFS and PFS results. The results of multivariate analysis exhibited that the PM was independently associated with each of the OS (P<0.001), LRPFS (P<0.001), and PFS (P<0.001) outcomes. Conclusion: The pretreatment PNI appears to be a robust novel prognostic factor that stratifies patients with stage IIIB NSCLC into two significantly distinct survival groups after CRT.

    Prognostic Value of Pretreatment Systemic Immune-Inflammation Index in Glioblastoma Multiforme Patients Undergoing Postneurosurgical Radiotherapy Plus Concurrent and Adjuvant Temozolomide
    (2020) Topkan, Erkan; Besen, Ali Ayberk; Ozdemir, Yurday; Kucuk, Ahmet; Mertsoylu, Huseyin; Pehlivan, Berrin; Selek, Ugur; 0000-0002-1932-9784; 0000-0002-2218-2074; 0000-0001-8120-7123; 0000-0002-7862-0192; 32565725; M-9530-2014; AAG-5629-2021; AAG-2213-2021; AAD-6910-2021
    Objectives. To evaluate the potential prognostic utility of pretreatment systemic immune-inflammation index (SII) in newly diagnosed glioblastoma multiforme (GBM) patients who underwent postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide. Methods. The retrospective data of GBM patients who underwent postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide were analyzed. For each patient, SII was calculated using the platelet, neutrophil, and lymphocyte measures obtained on the first day of treatment: SII=plateletsxneutrophils/lymphocytes. The receiver operating characteristic (ROC) curve analysis was utilized for the evaluation of optimal cut-off values for SII those linked with the outcomes. Primary and secondary endpoints constituted the overall (OS) and progression-free survival (PFS) per conveyance SII group. Results. A total of 167 patients were included. The ROC curve analysis identified the optimum SII cut-off at a rounded 565 value that significantly interacted with the PFS and OS and stratified patients into two groups: low-SII (SII<565; n=71) and high-SII (SII >= 565; n=96), respectively. Comparative survival analyses exhibited that the high-SII cohort had significantly shorter median PFS (6.0 versus 16.6 months; P<0.001) and OS (11.1 versus 22.9 months; P<0.001) than the low-SII cohort. The relationship between the high-SII and poorer PFS (P<0.001) and OS (P<0.001) further retained its independent significance in multivariate analysis, as well. Conclusions. The outcomes displayed here qualified the pretreatment SII as a novel independent prognostic index for predicting survival outcomes of newly diagnosed GBM patients undergoing postneurosurgical radiotherapy and concurrent plus adjuvant temozolomide.

    Prognostic Value of C-Reactive Protein to Albumin Ratio in Glioblastoma Multiforme Patients Treated with Concurrent Radiotherapy and Temozolomide
    (2020) Topkan, Erkan; Besen, Ali A.; Mertsoylu, Huseyin; Kucuk, Ahmet; Pehlivan, Berrin; Selek, Ugur; 0000-0002-7862-0192; 0000-0002-1932-9784; 0000-0001-8120-7123; 32566124; AAD-6910-2021; M-9530-2014; AAG-2213-2021
    Objective. We investigated the prognostic impact of C-reactive protein to albumin ratio (CRP/Alb) on the survival outcomes of newly diagnosed glioblastoma multiforme (GBM) patients treated with radiotherapy (RT) and concurrent plus adjuvant temozolomide (TMZ).Methods. The pretreatment CRP and Alb records of GBM patients who underwent RT and concurrent plus adjuvant TMZ were retrospectively analyzed. The CRP/Alb was calculated by dividing serum CRP level by serum Alb level obtained prior to RT. The availability of significant cutoff value for CRP/Alb that interacts with survival was assessed with the receiver-operating characteristic (ROC) curve analysis. The primary endpoint was the association between the CRP/Alb and the overall survival (OS).Results. A total of 153 patients were analyzed. At a median follow-up of 14.7 months, median and 5-year OS rates were 16.2 months (95% CI: 12.5-19.7) and 9.5%, respectively, for the entire cohort. The ROC curve analysis identified a significant cutoff value at 0.75 point (area under the curve: 74.9%; sensitivity: 70.9%; specificity: 67.7%;P<0.001) for CRP/Alb that interacts with OS and grouped the patients into two: CRP/Alb <0.75 (n = 61) and >= 0.75 (n = 92), respectively. Survival comparisons revealed that the CRP/Alb <0.75 was associated with a significantly superior median (22.5 versus 15.7 months;P<0.001) and 5-year (20% versus 0%) rates than the CRP/Alb >= 0.75, which retained its independent significance in multivariate analysis (P<0.001).Conclusion. Present results suggested the pretreatment CRP/Alb as a significant and independent inflammation-based index which can be utilized for further prognostic lamination of GBM patients.

    Low Systemic Inflammation Response Index Predicts Good Prognosis in Locally Advanced Pancreatic Carcinoma Patients Treated with Concurrent Chemoradiotherapy
    (2020) Topkan, Erkan; Mertsoylu, Huseyin; Kucuk, Ahmet; Besen, Ali Ayberk; Sezer, Ahmet; Sezen, Duygu; Bolukbasi, Yasemin; Selek, Ugur; Pehlivan, Berrin; 0000-0002-7862-0192; 0000-0002-6445-1439; 0000-0002-1932-9784; 0000-0001-8120-7123; AAD-6910-2021; AAD-2667-2020; M-9530-2014; AAG-2213-2021
    Background. We investigated the prognostic significance of pretreatment systemic inflammation response index (SIRI) in locally advanced pancreatic carcinoma (LAPC) patients treated with concurrent chemoradiotherapy (CRT). Methods. Present retrospective cohort analysis investigated consecutive 154 LAPC patients who received radical CRT. The SIRI was defined as:SIRI=neutrophilxmonocyte/lymphocyte counts. Ideal SIRI cutoff(s) influencing overall survival (OS) and progression-free survival (PFS) results were sought by using receiver operating characteristic (ROC) curve analysis. The primary endpoint was the interaction between the SIRI and OS results. Results. The median follow-up, PFS, and OS durations were 14.3 (range: 2.9-74.6), 7.9 [%95 confidence interval (CI): 5.7-10.1), and 14.7 months (%95 CI: 11.4-18.0) for the entire cohort, respectively. ROC curve analyses determined the ideal SIRI cutoff that exhibiting a significant link with OS and PFS outcomes at the rounded 1.6 point (AUC: 74.3%; sensitivity: 73.8%; specificity: 70.1%).The SIRI <1.6 patients (N=58) had significantly superior median PFS (13.8 versus 6.7 months; P<0.001) and OS (28.6 versus 12.6 months; P<0.001) lengths than SIRI >= 1.6 patients (N=96), respectively. Although the N0 (versus N1; P<0.05) and CA 19-9 <= 90 U/mL (versus >90 U/mL) appeared as the other significant associates of better OS and PFS in univariate analyses, yet the results of multivariate analyses confirmed the SIRI <1.6 as the independent indicator of superior OS and PFS (P<0.001 for each). Conclusion. Pretreatment SIRI is a novel independent prognosticator that may further enhance the conventional tumor-node-metastases staging system in a more precise prediction of the OS and PFS outcomes of LAPC patients after radical CRT.

    Comparison of Involved Field Radiotherapy versus Elective Nodal Irradiation in Stage IIIB/C Non-Small-Cell Lung Carcinoma Patients Treated with Concurrent Chemoradiotherapy: A Propensity Score Matching Study
    (2020) Topkan, Erkan; Ozdemir, Yurday; Guler, Ozan Cem; Kucuk, Ahmet; Besen, Ali Ayberk; Mertsoylu, Huseyin; Sezen, Duygu; Akdemir, Eyub Yasar; Sezer, Ahmet; Bolukbasi, Yasemin; Pehlivan, Berrin; Selek, Ugur; 0000-0002-1932-9784; 0000-0001-6908-3412; 0000-0002-2218-2074; 0000-0002-6445-1439; 0000-0001-8120-7123; 0000-0002-7862-0192; 32952557; M-9530-2014; AAC-5654-2020; AAG-5629-2021; AAD-2667-2020; AAG-2213-2021; AAD-6910-2021
    Background. We retrospectively compared the incidence of isolated elective nodal failure (IENF) and toxicity rates and survival outcomes after elective nodal irradiation (ENI) versus involved-field RT (IFRT) by employing the propensity score matching (PSM) methodology in stage IIIB/C inoperable non-small-cell lung cancer (NSCLC) patients treated with definitive concurrent chemoradiotherapy (C-CRT).Methods. Our PSM examination included 1048 stage IIIB/C NSCLC patients treated with C-CRT from January 2007 to December 2016: a total dose of 66 Gy (2 Gy/fraction) radiotherapy and 1-3 cycles of platinum-based doublet chemotherapy concurrently. The primary and secondary endpoints were the IENF and toxicity rates and survival outcomes after ENI versus IFRT, respectively. Propensity scores were calculated for each group to adjust for confounding variables and facilitate well-balanced comparability by creating 1 : 1 matched study groups.Results. The median follow-up was 26.4 months for the whole study accomplice. The PSM analysis unveiled 1 : 1 matched 646 patients for the ENI (N = 323) and IFRT (N = 323) cohorts. Intergroup comparisons discovered that the 5-year isolated ENF incidence rates (3.4% versus 4.3%;P=0.52) and median overall survival (25.2 versus 24.6 months;P=0.69), locoregional progression-free survival (15.3 versus 15.1 months;P=0.52), and progression-free survival (11.7 versus 11.2 months;P=0.57) durations were similar between the ENI and IFRT cohorts, separately. However, acute grade 3-4 leukopenia (P=0.0012), grade 3 nausea-vomiting (P=0.006), esophagitis (P=0.003), pneumonitis (P=0.002), late grade 3-4 esophageal toxicity (P=0.038), and the need for hospitalization (P<0.001) were all significantly higher in the ENI than in the IFRT group, respectively.Conclusion. Results of the present large-scale PSM cohort established the absence of meaningful IENF or survival differences between the IFRT and ENI cohorts and, consequently, counseled the IFRT as the elected RT technique for such patients since ENI increased the toxicity rates.

    Half-dose bevacizumab experience in relapsed ovarian cancer patients in Turkey due to formal regulations: similar effectiveness with lower rate of hypertension
    (2020) Kose, Fatih; Alemdaroglu, Songul; Mertsoylu, Huseyin; Besen, Ali Ayberk; Guler, Ozan Cem; Simsek, Seda Yuksel; Erbay, Gurcan; Onal, Cem; Celik, Husnu; 0000-0003-4335-6659; 0000-0002-2742-9021; 0000-0001-6908-3412; 0000-0002-1706-8680; 0000-0002-0156-5973; 0000-0002-7862-0192; 0000-0002-1932-9784; 33099934; AAI-8400-2021; D-5195-2014; AAC-5654-2020; AAK-5370-2021; G-4827-2016; AAK-7016-2021; AAD-6910-2021; M-9530-2014
    Purpose: Ovarian cancer is the fifth leading cause of cancer related death in women. Platin-based doublet regimens plus bevacizumab is standard treatment in relapse. Due to formal regulation of Turkish Ministry of Health, adjuvant bevacizumab has not been reimbursed and clinicians can use bevacizumab at a dose of 7.5 mg/kg/3wk in platin-resistant and sensitive relapse settings. The primary aim of this study was to evaluate 7.5 mg/kg/3wk bevacizumab dosing in platin-resistant and sensitive relapse ovarian cancer and compare these findings with the current literature. Methods: A total of 106 patients with relapsed ovarian cancer and treated with bevacizumab (bevacizumab is not reimbursed as a part of adjuvant treatment in Turkey) on their first relapse were included. Results: At a median follow-up of 32.1 months (5.3-110.8), 56 (52.8%) patients died. Progression-free survival (PFS) and overall survival (OS) were estimated at 18.8 months (14.4-23.3) vs 29.7 months (24.3-35.1) of the whole group overall survival. We observed that 78.4% of patients treated with primary surgery without neoadjuvant treatment and 59 (57.8%) out of the 102 patients with debulking surgery relapsed. A significant number of patients (81%) treated with primary surgery without neoadjuvant treatment and 59 (76.6 %) had secondary debulking surgery at relapse. In relapse, 38 patients were treated with single agent liposomal doxorubicin (LPD) plus bevacizumab. On the other hand, 68 patients were treated with carboplatin and LPD plus bevacizumab. Multivariate analysis failed to show any clinicopathological characteristics with significant effect on PFS. However, cytoreductive surgery at relapse showed significant effect on OS. Bevacizumab-related toxicities were detected in 23 (21.7%) patients; hypertension, pulmonary embolism, perforation, and other toxicities (nephrotic syndrome in 2, osteonecrosis in 2, cerebrovascular and cardiac ischemia in 3 patients) were seen in 12 (11.3%), 3 (2.8%), 1 (0.9%) and 7 (6.6%) patients, respectively. Conclusions: In conclusion, our findings showed that 7.5 mg/ kg/3week dosing of bevacizumab in relapsed ovarian cancer could have similar effectiveness compared to standard 15 mg/ kg/3week dosing. Increase of OS and PFS in patients treated with primary and secondary debulking surgery with no-visible disease was more pronounced. No new safety information was observed but lower rate of grade 3 or above hypertension with similar rate of severe vascular and intestinal complications were detected.

    Low Advanced Lung Cancer Inflammation Index Predicts Poor Prognosis in Locally Advanced Nasopharyngeal Carcinoma Patients Treated with Definitive Concurrent Chemoradiotherapy
    (2020) Topkan, Erkan; Ozdemir, Yurday; Kucuk, Ahmet; Guler, Ozan Cem; Sezer, Ahmet; Besen, Ali Ayberk; Mertsoylu, Huseyin; Senyurek, Sukran; Kilic Durankus, Nulifer; Bolukbasi, Yasemin; Selek, Ugur; Pehlivan, Berrin; 0000-0001-8120-7123; 0000-0002-7862-0192; 0000-0002-2218-2074; 0000-0001-6908-3412; 0000-0002-1932-9784; 0000-0002-6445-1439; 0000-0002-5361-364X; 33082783; AAG-2213-2021; AAD-6910-2021; AAG-5629-2021; AAC-5654-2020; M-9530-2014; AAD-2667-2020
    Purpose. We aimed to retrospectively investigate the prognostic worth of pretreatment advanced lung cancer inflammation index (ALI) in locally advanced nasopharyngeal carcinoma (LA-NPC) patients treated with concurrent chemoradiotherapy (C-CRT).Patients and Methods. A total of 164 LA-NPC patients treated with cisplatinum-based definitive C-CRT were included in this retrospective cohort analysis. The convenience of ideal pre-C-CRT ALI cut-offs affecting survival results was searched by employing the receiver operating characteristic (ROC) curve analyses. The primary endpoint was the link between the ALI groups and overall survival (OS), while cancer-specific survival (CSS), locoregional progression-free survival [LR(PFS)], distant metastasis-free survival (DMFS), and PFS comprised the secondary endpoints.Results. The ROC curve analyses distinguished a rounded ALI cut-off score of 24.2 that arranged the patients into two cohorts [ALI >= 24.2 (N = 94) versus < 24.2 (N = 70)] with significantly distinct CSS, OS, DMFS, and PFS outcomes, except for the LRPFS. At a median follow-up time of 79.2 months (range: 6-141), the comparative analyses showed that ALI < 24.2 cohort had significantly shorter median CSS, OS, DMFS, and PFS time than the ALI >= 24.2 cohort (P<0.001for each), which retained significance at 5- (P<0.001) and 10-year (P<0.001) time points. In multivariate analyses, ALI < 24.2 was asserted to be an independent predictor of the worse prognosis for each endpoint (P<0.001for each) in addition to the tumor stage (T-stage) (P<0.05for all endpoints) and nodal stage (N-stage) (P<0.05for all endpoints).Conclusion. As a novel prognostic index, the pretreatment ALI < 24.2 appeared to be strongly associated with significantly diminished survival outcomes in LA-NPC patients treated with C-CRT independent of the universally recognized T- and N-stages.
