[PMID: 37594526 DOI: 10.1007/s00330-023-09987-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 06/05/2023] [Accepted: 06/12/2023] [Indexed: 08/19/2023]
Abstract
OBJECTIVES To develop a contrast-enhanced CT (CECT) radiomics-based model to identify locoregionally advanced nasopharyngeal carcinoma (LA-NPC) patients who would benefit from deintensified chemoradiotherapy. METHODS LA-NPC patients who received low-dose concurrent cisplatin therapy (cumulative: 150 mg/m2), were randomly divided into training and validation groups. 107 radiomics features based on the primary nasopharyngeal tumor were extracted from each pre-treatment CECT scan. Through Cox regression analysis, a radiomics model and patients' corresponding radiomics scores were created with predictive independent radiomics features. T stage (T) and radiomics score (R) were compared as predictive factors. Combining the N stage (N), a clinical model (T + N), and a substitution model (R + N) were constructed. RESULTS Training and validation groups consisted of 66 and 33 patients, respectively. Three significant independent radiomics features (flatness, mean, and gray level non-uniformity in gray level dependence matrix (GLDM-GLN)) were found. The radiomics score showed better predictive ability than the T stage (concordance index (C-index): 0.67 vs. 0.61, AUC: 0.75 vs. 0.60). The R + N model had better predictive performance and more effective risk stratification than the T + N model (C-index: 0.77 vs. 0.68, AUC: 0.80 vs. 0.70). The R + N model identified a low-risk group as deintensified chemoradiotherapy candidates in which no patient developed progression within 3 years, with 5-year progression-free survival (PFS) and overall survival (OS) both 90.7% (hazard ratio (HR) = 4.132, p = 0.018). CONCLUSION Our radiomics-based model combining radiomics score and N stage can identify specific LA-NPC candidates for whom de-escalation therapy can be performed without compromising therapeutic efficacy. CLINICAL RELEVANCE STATEMENT Our study shows that the radiomics-based model (R + N) can accurately stratify patients into different risk groups, with satisfactory prognosis in the low-risk group when treated with low-dose concurrent chemotherapy, providing new options for individualized de-escalation strategies. KEY POINTS • A radiomics score, consisting of 3 predictive radiomics features (flatness, mean, and GLDM-GLN) integrated with the N stage, can identify specific LA-NPC populations for deintensified treatment. • In the selection of LA-NPC candidates for de-intensified treatment, radiomics score extracted from primary nasopharyngeal tumors based on CECT can be superior to traditional T stage classification as a predictor.

Meng Y, Huang C, Huang W. Survival after induction chemotherapy in locoregional advanced nasopharyngeal carcinoma: An updated systematic review and meta-analysis. Laryngoscope Investig Otolaryngol 2023; 8:1217-1225. [PMID: 37899875 PMCID: PMC10601584 DOI: 10.1002/lio2.1133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/18/2023] [Accepted: 08/02/2023] [Indexed: 10/31/2023] Open
Abstract
Background Induction chemotherapy (ICT) augmentation is a common strategy for standard concurrent chemoradiotherapy (CCRT) of locoregionally advanced nasopharyngeal carcinoma (NPC). The survival condition is a crucial issue for patients with locoregionally advanced NPC. The survival of ICT patients with CCRT treatment versus standard CCRT alone should be elucidated via a systemic review and meta-analysis of randomized clinical trials. Methods We compared ICT with CCRT and CCRT alone treatment to determine if ICT with CCRT can be associated with a significant benefit of survival conditions versus CCRT. Different survival indicators were analyzed for the ICT with CCRT. Twelve studies with a total of 3711 patients with locoregionally advanced NPC were enrolled. The focused outcome was the overall survival, progression-free survival, distant metastasis-free survival, and locoregional recurrence-free survival. Results Our results showed that ICT with CCRT is associated with a significant benefit for the overall survival status versus CCRT treatment. Similar significant benefits in the survival condition were seen in progression-free survival, distant metastasis-free survival, and locoregional recurrence-free survival. Conclusions The updated meta-analysis results suggest that the ICT with CCRT might be associated with significant benefits of survival in overall, progression-free, distant metastasis-free, as well as locoregional recurrence-free dimensions versus CCRT treatment. However, the bias of different kinds, doses, and regimens of chemotherapy agents and radiotherapy should not be ignored.

Abstract
BACKGROUND A nomogram that incorporates tumor response at mid-radiotherapy (mid-RT) to predict the prognosis of locoregionally advanced nasopharyngeal carcinoma (LA-NPC) has not been established. METHODS This study retrospectively reviewed 583 patients with LA-NPC who underwent magnetic resonance imaging scans at mid-RT (the fourth week of RT) between 2015 and 2019. RESULTS Primary tumor (PT) response at mid-RT was found to predict disease-free survival (DFS) and overall survival (OS). Independent factors from multivariable analysis to predict DFS and OS were assembled into nomograms with (nomograms Amid-RT and Bmid-RT ) or without (nomograms Abaseline and Bbaseline ) PT response. Internal validation revealed good performance of these nomograms in discrimination: C-statistics = 0.761 for nomogram Amid-RT and 0.809 for nomogram Bmid-RT , which showed better discrimination performance than (C-statistics: 0.755) nomogram Abaseline and (C-statistics: 0.798) nomogram Bbaseline (Z-statistic = 2.476, p < 0.05; Z-statistic = 1.971, p < 0.05). CONCLUSION The nomograms based on PT response at mid-RT showed favorable predictive accuracy for DFS and OS in patients with LA-NPC.

Recombinant human endostatin injection (Endostar) combined with PF chemotherapy and sequential intensity-modulated radiotherapy is tolerable and improves prognosis of locally advanced nasopharyngeal carcinoma: a randomized, open, multicenter phase II clinical study. Am J Cancer Res 2022; 12:4622-4636.

Abstract
Nasopharyngeal carcinoma (NPC) is not only a common malignant disease of the head and neck, but also presented as locoregionally advanced NPC at diagnosis with poor prognosis. The efficacy of current chemoradiotherapy is unsatisfactory; therefore, in this study, we evaluated the safety and efficacy of treating locally advanced NPC using recombinant human endostatin injection (Endostar), combined with a cisplatin plus 5-fluorouracil (PF) regimen and sequential intensity-modulated radiotherapy (IMRT), and compared it with PF plus IMRT regimen. This phase II study included 83 eligible patients with stages III-IVa NPC (8th AJCC/UICC) who were randomized 1:1 into control (n = 42) and experimental (n = 41) groups. The control group received PF chemotherapy and IMRT for locally advanced NPC; One cycle of induction chemotherapy (IC) was administered before IMRT, and three cycles of adjuvant chemotherapy (AC) were administered four weeks post-radiotherapy. The experimental group received additional Endostar therapy. All patients were followed up for at least 5 years. The primary endpoints were progression-free survival (PFS) and the objective response rate. The secondary endpoints included overall survival and treatment-related toxicities. The short-term efficacy was evaluated at the end of the fourth chemotherapy cycle. Our results showed that the complete response rate of nasopharyngeal lesions was not significantly different between the experimental and control groups (80.5 vs. 71.4%, P = 0.335); however, there were significant differences in the complete response rates of cervical metastatic lymph nodes (75.6 vs. 40.5%, P = 0.001), especially for cervical N3 lymph nodes in the experimental group (55.6 vs. 9.5%, P = 0.004). The overall median follow-up time was 69.7 months. Patients in the experimental group showed significantly prolonged PFS by about four months (hazard ratio [HR] = 0.64, 95% CI: 0.41-0.99, P = 0.045). There was no significant difference in the median overall survival (P = 0.374). Furthermore, subgroup analysis indicated that the risk of death in patients with cervical N3 lymph nodes in the experimental group was reduced by 52% (HR = 0.48, 95% CI: 0.23-0.99, P = 0.046). Moreover, the incidence of radiation-induced grades 3-4 oral mucositis was significantly lower in the experimental group (29.3% vs. 54.8%, P = 0.019), while no significant differences in other severe adverse reactions were observed between the two groups (P>0.05). Taken together, our study indicated that, in patients with locally advanced NPC, Endostar in combination with PF chemotherapy and sequential IMRT significantly improved PFS, had tolerable treatment-related toxicities, improved the prognoses of patients with cervical N3 lymph nodes, and reduced the incidence of radiation-related oral mucositis.
