Survival outcome and prognostic factors of patients with nasopharyngeal cancer in Yogyakarta, Indonesia: A hospital-based retrospective study

Multidisciplinary Team Meeting in the Core of Nasopharyngeal Cancer Management Improved Quality of Care and Survival of Patients

Nasopharyngeal cancer (NPC) cases are often diagnosed in advanced stages. The complexity of clinical management for advanced-stage NPC requires thorough communication and shared decisions between medical professionals and allied teams. Incorporating a multidisciplinary team meeting (MDTM) for newly diagnosed NPC patients was chosen to facilitate collaboration and communication between physicians. This retrospective study aimed to compare the quality of care, clinical responses and survival between NPC patients treated with and without MDTM. Data on clinical responses, assessment visits, date of progression and death with progression-free survival (PFS), overall survival (OS), and hazard ratio (HR) were collected and analyzed with 95% confidence interval (CI) and significance set as P < .05. There were 87 of 178 NPC patients treated with MDTM. Revisions of diagnosis and stage occurred in 5.7% and 52.9% of cases during the MDTM. More clinical responses were achieved by patients treated with MDTM (69.0%vs 32.0%, P < .00). NPC patients who received MDTM treatment recommendation had a lower risk for progression (median PFS 59.89 months vs 12.68 months; HR 0.267, 95% CI: 0.17-0.40, P < .00) and mortality (median OS was not reached vs 13.44 months; HR 0.134, 95% CI: 0.08-0.24, P < .00) compared to patients without MDTM. Incorporating the MDTM approach into NPC management improves patients' clinical responses and survival.

Impact of independent multidisciplinary work on the survival rate of stage 3 and 4 nasopharyngeal cancer in Indonesia: a retrospective cohort study

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.

Pretreatment Body Mass Index (BMI) as an Independent Prognostic Factor in Nasopharyngeal Carcinoma Survival: A Systematic Review and Meta-Analysis

We performed a meta-analysis to investigate the association between pretreatment body mass index (BMI) and prognosis of nasopharyngeal carcinoma (NPC). Case-control and cohort studies were searched from PubMed, Web of Science, EMBASE, and CNKI databases. Pooled hazard ratios (HR) with 95% confidence intervals (CI) for overall survival (OS) or distant metastasis-free survival (DMSF) were used to estimate the prognostic value. Bias in the included studies was evaluated using funnel plots. The results showed that compared with normal weight patients, the estimated HR of OS was 1.54 (95% CI: 1.25-1.90; P < 0.05) for underweight, 0.63 (95% CI: 0.48-0.83; P < 0.05) for overweight, and 0.67 (95% CI: 0.41-1.08; P = 0.102) obese patients. We also found that compared with normal-weight patients, the estimated HR of DMFS was 1.63 (95% CI: 1.38-1.92; P < 0.05) for underweight, 0.83 (95% CI: 0.61-1.13; P = 0.244) for overweight, and 0.60 (95% CI: 0.39-0.92; P < 0.05) for patients with obesity. BMI is an independent prognostic factor for NPC survival. Being underweight before treatment was associated with poorer OS and DMFS in patients with NPC. Neither overweight nor obesity before treatment has an unfavorable effect on NPC survival.

Health Insurance Coverage and Survival Outcomes among Nasopharyngeal Carcinoma Patients: A SEER Retrospective Analysis

Objectives Insurance coverage plays a critical role in head and neck cancer care. This retrospective study examines how insurance coverage affects nasopharyngeal carcinoma (NPC) survival in the United States using the Surveillance, Epidemiology, and End Results (SEER) program database.

Design, Setting, and Participants A total of 2,278 patients aged 20 to 64 years according to the International Classification of Diseases for Oncology (ICD-O) codes C11.0–C11.9 and ICD-O histology codes 8070–8078 and 8080–8083 between 2007 and 2016 were included and grouped into privately insured, Medicaid, and uninsured groups. Log-rank test and multivariable Cox's proportional hazard model were performed.

Main Outcome Measures Tumor stage, age, sex, race, marital status, disease stage, year of diagnosis, median household county income, and disease-specific survival outcomes including cause of death were analyzed.

Results Across all tumor stages, privately insured patients had a 59.0% lower mortality risk than uninsured patients (hazard ratio [HR]: 0.410, 95% confidence interval [CI]: [0.320, 0.526], p < 0.01). Medicaid patients were also estimated to have 19.0% lower mortality than uninsured patients (HR: 0.810, 95% CI: [0.626, 1.048], p = 0.108). Privately insured patients with regional and distant NPC had significantly better survival outcomes compared with uninsured individuals. Localized tumors did not show any association between survival and type of insurance coverage.

Conclusion Privately insured individuals had significantly better survival outcomes than uninsured or Medicaid patients, a trend that was preserved after accounting for tumor grade, demographic and clinicopathologic factors. These results underscore the difference in survival outcomes when comparing privately insured to Medicaid/uninsured populations and warrant further investigation in efforts for health care reform.

Efficacy of the Nourishing Yin and Clearing Heat Therapy Based on Traditional Chinese Medicine in the Prevention and Treatment of Radiotherapy-Induced Oral Mucositis in Nasopharyngeal Carcinomas: A Systematic Review and Meta-Analysis of Thirty Randomized Controlled Trials

This study aimed to evaluate the efficacy of nourishing Yin and clearing heat therapy (NYCH therapy) based on traditional Chinese medicine (TCM) in the treatment of radiotherapy-induced oral mucositis (RTOM) in nasopharyngeal carcinomas (NPCs). A total of eight online databases were searched from inception to September 2021 for randomized controlled trials (RCTs). The control group was treated with Western medicine (WM) alone, whereas the experimental group was treated with a combined NYCH and WM therapy. A total of 30 RCTs involving 2562 participants were ultimately included. NYCH therapy combined with conventional WM delayed the onset time (days) of RTOM (MD = 10.80, p < 0.001), and at that time, a higher cumulative radiotherapy dose (Gy) (MD = 5.72, p < 0.001) was completed in the experimental group. The combination regimen also reduced the incidence of severe oral mucositis (Grade III–IV) (RR = 0.25, p < 0.001). In addition, the treatment efficacy of the experimental group was significantly better than that of the control group (RR = 1.31, p < 0.001). Compared with the patients in the control group, the experimental group had lower xerostomia scores (MD = -1.07, p < 0.001) and more saliva (MD = 0.36, p < 0.001). NYCH combined with WM improved the efficacy of treating RTOM in NPC. This study provides a sufficient basis for conducting further large RCTs to prove the efficacy of NYCH.

Epidemiological Profile and Clinicopathological, Therapeutic, and Prognostic Characteristics of Nasopharyngeal Carcinoma in Northern Morocco

Background

Nasopharyngeal carcinoma is a multifactorial disease mainly affecting the Asian and North African populations including Morocco. This study aimed to determine the epidemiological profile of nasopharyngeal carcinoma in Northern Morocco as well as its clinicopathological, therapeutic, and prognostic characteristics.

Methods

129 patients with nasopharyngeal carcinoma followed at the regional center of oncology of Tangier in the period between April 2017 and July 2019, and diagnosed elsewhere from March 2000 to February 2019, were included in this study. Statistical analysis of the data was realized using Statistical Package for the Social Sciences (SPSS) software.

Results

Nasopharyngeal carcinoma (NPC) represented 5% of all cases with a median age of 50. The most affected age group was 40–54 years (41.1%). Of all patients, 65.9% were men and 34.1% were women with a sex ratio of 1.93 (Male/Female). Undifferentiated nasopharyngeal carcinomas were the most common histological type affecting 96.12% of patients. At diagnosis, the majority of patients (82.2%) had an advanced stage of NPC (III, VIa, b, c) including 5.4% of metastatic cases (IVc). Most cases (86%) had lymph node involvement with cervical mass being the most common clinical presentation. 81.4% of patients received radiotherapy combined with chemotherapy. Among these patients, 54.3% had concurrent radiochemotherapy preceded by induction chemotherapy. The 5-year overall survival (OS) was 86.8% for all patients. It represented 91.3% for early stages, 87.9% for locally advanced stages, and 57.1% for the metastatic stage significantly. The disease-free survival (DFS) at 5 years was 87.6% knowing that relapse occurred in 16 cases.

Conclusions

Nasopharyngeal carcinoma is a particular disease with a late declaration. It is common in Morocco as is the case in other endemic areas with a high prevalence. Patients’ survival is significantly influenced by disease staging.
