Abstract
Background The utilization of a multidisciplinary team (MDT) strategy is a beneficial approach in integrating the knowledge and proficiencies of various fields to produce thorough and advantageous cancer treatment plans for patients. Nevertheless, MDT has yet to be widely adopted in Indonesia. In this study, the authors examined an early form of MDT in Indonesia that does not involve dedicated meetings, referred as independent multidisciplinary work (IMW). The objective is to investigate the differences in survival rates of nasopharyngeal cancer (NPC) patients who underwent treatment with and without IMW. Materials and methods This study has a retrospective cohort design. Data were collected from the medical records of newly diagnosed stage 3 and 4 NPC patients between 2016 and 2018. The subjects were divided into two groups: the IMW group and the non-IMW group. The primary end point of the study is overall survival rate between the two groups. Kaplan-Meier survival analysis, log-rank test, and cox proportional hazard analysis were used for statistical analysis. Results This study included a total of 124 patients with NPC, 81 patients in the IMW group and 43 patients in the non-IMW group. At the end of the 36-month follow-up period, the median survival of the IMW group was not reached, while in the non-IMW, it was 12 months [95% confidence intervals (95% CI), 8.78-15.22], hazard ratio (HR): 0.47 (95% CI, 0.28-0.78; P<0.01). The 1-year survival rate was 66.7% in the IMW group versus 46.5% in the non-IMW group (HR=0.7, 95% CI 0.49-0.99; P=0.03); the 2-year survival rate was 40.7% in the IMW group versus 16.3% in the non-IMW group (HR=0.4, 95% CI 0.19-0.83; P<0.01). Daniel Rizky, Vina Yunarvika, and Yasjudan Rastrama Putra, these authors contributed equally to this work. In the multivariate analysis, the IMW approach, ECOG (The Eastern Cooperative Oncology Group) status, distant metastasis, and treatment approach were significantly associated with survival outcome. Conclusion The use of IMW approach in the treatment of NPC was associated with a better survival outcome compared to non-IMW treatment.

Abstract
PURPOSE To investigate whether the addition of fluorouracil to docetaxel and cisplatin induction chemotherapy (IC) can truly improve the prognosis of patients with locoregionally advanced nasopharyngeal carcinoma (NPC). METHODS A total of 801 patients newly diagnosed with non-metastatic locoregionally advanced NPC were included as the subjects. In this study, propensity score matching (PSM) was used for analysis of overall survival (OS), distant metastasis-free survival (DMFS), progression-free survival (PFS) and locoregional relapse-free survival (LRRFS), and the chi-squared test or Fisher's exact test was used to investigate toxic reactions. RESULTS Patients received treatment with docetaxel and cisplatin (TP) or docetaxel, cisplatin and fluorouracil (TPF). With a median follow-up time of 60 months (range: 5-124 months), the TPF group had better 5-year OS (84.7% vs 79.0%; P = 0.037), PFS (84.6% vs 76.8%; P = 0.008) and DMFS (89.5% vs 82.3%; P = 0.004) than the TP group. After PSM, 258 patients were matched in each cohort. The Kaplan-Meier analysis showed that the 5-year OS, PFS and DMFS were 85.5%, 84.2% and 89.2%, respectively, in the TPF group, higher than the 80.8%, 75.0% and 81.4%, respectively, in the TP group (P = 0.048, 0.009 and 0.006, respectively). Moreover, the multivariate analysis revealed that different IC regimens were independent prognostic factors for PFS and DMFS (P = 0.014 and 0.010, respectively). CONCLUSION This study found that compared with the TP regimen, TPF induction chemotherapy is associated with improved survival in patients with locoregionally advanced NPC. TPF can produce more mucosal and nausea/vomiting adverse reactions than TP.

J Med Imaging Radiat Oncol 2022; 66:853-865. [PMID: 35302281 DOI: 10.1111/1754-9485.13400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 02/14/2022] [Accepted: 02/20/2022] [Indexed: 11/28/2022]
Abstract
INTRODUCTION T4 nasopharyngeal carcinoma (NPC) with close proximity to critical organs at risk (OARs) is usually underdosed during radiotherapy in order to respect radiation constraints. N3 disease has high risk of distant metastasis. Induction chemotherapy (IC) provides advantages of sparing of OARs during subsequent chemoradiotherapy (CCRT) and early eradication of micrometastasis. However, factors predicting successes of IC in this patient group are not well-studied. METHODS 104 T4 or N3 NPC patients were retrospectively reviewed during 2007-2018. They were planned for IC followed by CCRT using intensity-modulated radiotherapy. RESULTS In the whole group, five-year failure-free survival (FFS), locoregional failure-free survival (LRFS), distant failure-free survival (DFFS) and overall survival (OS) were 40.9%, 45.7%, 46.9% and 53.6% respectively. Isolated marginal failure rate was 5% (4/80) among patients with primary tumours located close to critical OARs. Pre-IC gross tumour volume primary (GTVp) total volume > 110 cm3 correlated with worse five-year LRFS (OR 6.37, P = 0.008), DFFS (OR 8.89, P = 0.003) and OS (OR 50.12, P < 0.001). In the T4 subgroup, IC improved D100% GTVp from 61.39 Gy to 64.71 Gy (P < 0.001) and V100% GTVp from 98.78% to 99.28% (P < 0.001). CONCLUSION Our study demonstrated improved dosimetric parameters and low isolated marginal failure rate. It supported the use of IC and CCRT for tumours located close to critical OARs. Further research is warranted to compare predictive roles of pre- and post-IC tumour volumes. For high-risk patients being defined by pre-IC volume or other prognostic models, treatment escalation should be considered.

Abstract
Purpose This study aimed to determine the survival outcome and prognostic factors of patients with nasopharyngeal cancer accessing treatment in Yogyakarta, Indonesia. Methods Data on 759 patients with NPC diagnosed from 2007 to 2016 at Dr Sardjito General Hospital were included. Potential prognostic variables included sociodemographic, clinicopathology and treatment parameters. Multivariable analyses were implemented using semi-parametric Cox proportional hazards modelling and fully parametric survival analysis. Results The median time of observation was 14.39 months. In the whole cohort the median observed survival was 31.08 months. In the univariable analysis, age, education status, insurance type, BMI, ECOG index, stage and treatment strategy had an impact on overall survival (OS) (p values <0.01). Semi-parametric multivariable analyses with stage stratification showed that education status, ECOG index, and treatment modality were independent prognostic factors for OS (p values <0.05). In the fully parametric models age, education status, ECOG index, stage, and treatment modality were independent prognostic factors for OS (p values <0.05). For both multivariable analyses, all treatment strategies were associated with a reduced hazard (semi-parametric models, p values <0.05) and a better OS (parametric models, p values <0.05) compared with no treatment. Furthermore, compared with radiation alone or chemotherapy alone, a combination of chemotherapy and radiation either in a form of concurrent chemoradiotherapy (CCRT), sequential chemotherapy and radiation, or induction chemotherapy followed by CCRT demonstrated a reduced hazard (hazard ratio/HR 0.226, 95% confidence interval/CI 0.089–0.363, and HR 0.390, 95%CI 0.260–0.519) and a better OS (time ratio/TR 3.108, 95%CI 1.274–4.942 and TR 2.531, 95%CI 1.829–3.233) (p values < 0.01). Conclusions Median OS for the cohort was low compared to those reported in both endemic and non-endemic regions. By combining the findings of multivariable analyses, we showed that age, education status, ECOG index, stage and first treatment modality were independent predictors for the OS.

Abstract
OBJECTIVES Induction chemotherapy (IC) is gaining recognition for the treatment of nasopharyngeal carcinoma (NPC). We aimed to develop a model to predict benefit from additional IC to concurrent chemoradiotherapy (CCRT). MATERIALS AND METHODS From an NPC-specific database, 7413 patients with stage II-IVa disease who received CCRT with or without IC were included. Distant metastasis-free survival (DMFS) was the primary outcome and benefit from IC was evaluated by adjusted hazard ratio. Interaction terms between IC and other prognostic factors were identified in multivariate Cox model, and IC benefit score (ICBS) was calculated based on β coefficients from the Cox model. RESULTS Nodal category, overall stage, and pre-treatment plasma Epstein-Barr virus DNA (log transformed as continuous variable) interacted with IC and determined ICBS. ICBS could discriminate patients who benefited differently from IC in terms of DMFS well, especially for patients with high and low ICBS. As for patients with medium ICBS, predictive performance of ICBS seemed reduced. CONCLUSIONS Based on the ICBS model, we proposed a decision-making process to help in clinical practice. Multi-institutional and prospective studies are warranted to further validate our findings.

Abstract
OBJECTIVE Our objective was to examine whether adding induction chemotherapy to concurrent chemoradiotherapy improved survival in stage III nasopharyngeal carcinoma (NPC) patients, especially in low-risk patients at stage T3N0-1. MATERIALS AND METHODS We retrospectively analyzed 687 patients with stage T3N0-1 NPC treated with intensity-modulated radiation therapy (IMRT) plus concurrent chemotherapy (CC) with or without induction chemotherapy (IC). Propensity score matching (PSM) method was used to select 237 pairs of patients from two cohorts. Overall survival (OS), locoregional relapse-free survival (LRFS), distant metastasis-free survival (DMFS), and progression-free survival (PFS) were assessed by using the Kaplan-Meier method, log-rank test, and Cox regression analysis. RESULTS No significant survival differences were observed between IC plus CC and CC cohorts with similar 4-year OS (91.7% vs 92.6%, P=0.794), LRFS, (92.7% vs 96.8%, P=0.138), DMFS (93.5% vs 94.3%, P=0.582), and PFS (87.5% vs 91.1%, P=0.223). In a univariate analysis, lower Epstein-Barr virus deoxyribonucleic acid (EBV DNA; <4,000 copies/mL) significantly improved 4-year DMFS (95.5% vs 91.6%, P=0.044) compared with higher EBV DNA (≥4,000 copies/mL). No factors were associated with 4-year OS, LRFS, DMFS, and PFS in a multivariate analysis. IC plus CC group experienced higher rates of grade 3-4 leucopenia (P<0.001) and neutropenia (P<0.001). CONCLUSION The addition of IC to CC in stage T3N0-1 NPC patients treated with IMRT did not significantly improve their survival. The IC group experienced higher rates of grade 3-4 hematological toxicities. Therefore, further investigation is required.

Abstract
PURPOSE Whether neoadjuvant chemotherapy (NCT) followed by concurrent chemoradiotherapy (CCRT) could improve survival in nasopharyngeal carcinoma (NPC) remains controversial especially in the era of intensity-modulated radiation therapy (IMRT), and we explored the role of NCT for NPC patients. PATIENTS AND METHODS A retrospective review was conducted of 255 NPC patients treated with NCT+CCRT (n=67) or CCRT alone (n=188) based on IMRT between December 2006 and December 2012. To control the imbalance, a 1:2 match was performed using propensity score matching (PSM) method based on patient's heterogeneity and regimens of concurrent chemotherapy (CCT). The long-term treatment outcomes and toxicity between NCT group (n=67) and concurrent chemoradiotherapy (CRT) group (n=134) after PSM were compared. RESULTS The 5-year overall survival (OS), progression-free survival (PFS), recurrence-free survival (RFS), local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS) and distant failure-free survival (DFFS) were 78.8%, 69.1%, 90.0%, 90.0%, 100% and 78.3% for NCT group, while 79.5%, 75.7%, 92.7%, 94.2%, 96.1% and 82.7% for CRT group (P=0.305, 0.448, 0.790, 0.512, 0.104 and 0.671). It indicated that the treatment method (NCT+CCRT vs CCRT) was not the independent prognostic factor for the survival in NPC patients, and only patients who had completed at least two cycles of CCT got better OS, RFS and DFFS (P=0.009, 0.016 and 0.043), whether to receive NCT or not. No difference in the incidences of any acute and most late toxicity between the two groups was shown. CONCLUSION Our study did not show the exact advantage of NCT followed by CCRT compared with CCRT alone or higher incidences of toxicity in NCT group. It suggests that NCT might not be necessary if two or more cycles of CCT are finished well in the era of IMRT, and when NCT is finished well, less than two cycles of CCT with IMRT could be enough. However, in the era of IMRT, the role of NCT still needs to be further explored.
