Population Based Study

AbstractLymphoepithelial carcinoma (LEC) of the oral cavity and pharynx is uncommon, and the characteristics and survival remains unclear. The present study aims to describe the clinicopathological characteristics and determine the factors associated with survival of this uncommon cancer. A population-based study was carried out to investigate clinical characteristics and prognosis of LEC of the oral cavity and pharynx using the data from Surveillance, Epidemiology and End Results (SEER) database between 1988 and 2013. The propensity-matched analysis was conducted for prognostic analysis, and a prognostic nomogram was also constructed. Totally, 1025 patients with LEC of the oral cavity and pharynx were identified, including 769 nasopharyngeal LEC patients and 256 non-nasopharyngeal LEC patients. The median OS of all LEC patients was 232.0m (95% CI 169.0-258.0). The 1-, 5-, 10- and 20-year survival rates were 92.9%, 72.9%, 59.3%, and 46.8%, respectively. Surgery could significantly prolong the survival time of LEC patients (P<0.01, mOS: 190m vs. 255m). Radiotherapy, as well as radiotherapy after surgery, could prolong the mOS (P<0.01 for both). The survival analysis demonstrated that old age (>60 years), lymph node (N3) and distant metastases were independent factors for poor survival, whereas radiotherapy and surgery were independent factors for favorable survival. No significant differences in survival time between nasopharyngeal LEC and non-nasopharyngeal LEC patients were observed. The prognostic nomogram was established base on five independent prognostic factors (C-index=0.70; 95% CI 0.66-0.74). In conclusion, LEC of the oral cavity and pharynx is a rare disease, and old age, lymph node and distant metastases, surgery and radiotherapy were significantly associated with prognosis. The prognostic nomogram could be used to make individual predictions of OS.

In India, head and neck cancers (HNCA) account for 14.3% cancers at all sites. In North-eastern India, there is a high prevalence of HNCA which can be associated with pervasive habit of using tobacco, lime and betel. The alarmingly high prevalence of cancers of head and neck in this part of India has prompted us to take up this study. Ahospital-based study on prevalence of cancer in various head and neck regions like oropharynx, oral cavity, pharynx, larynx, salivary glands and nasal cavity was conducted in Department of Radiation Oncology, Assam Medical College and Hospital from June 2020 to May 2021.The prevalence is found to be signicantly high at 57.59%, affecting males more than females in the age group of 50-59 years. HNCA of hypopharynx and oral cavity constituted a major burden of total body cancer. This study hopes to quantify and analyse the HNCAspectrum and should help as a starting point for a much needed population based study in this region. Acomprehensive effort is required to identify the cause of such high prevalence of HNCAin this region of India, generate awareness and treatment options suited to meet this challenge.

The Impact

AbstractThe association between tumor Epstein-Barr virus (EBV) status and clinical outcome in Hodgkin lymphoma (HL) is controversial. This population-based study assessed the impact of EBV status on survival in age-stratified cohorts of adults with classic HL (cHL). Data from 437 cases were analyzed with a median follow-up of 93 months. Overall survival (OS) was significantly better for EBV-negative compared with EBV-positive patients (P &lt; .001), with 5-year survival rates of 81% and 66%, respectively; disease-specific survival (DSS) was also greater for EBV-negative patients (P = .03). The impact of EBV status varied with age at diagnosis. In patients aged 16 to 34 years, EBV-associated cases had a survival advantage compared with EBV-negative cases, but differences were not statistically significant (P = .21). Among patients 50 years or older, EBV positivity was associated with a significantly poorer outcome (P = .003). Excess deaths occurred in EBV-positive patients with both early- and advanced-stage disease. In multivariate analysis of OS in the older patients, EBV status retained statistical significance after adjusting for the effects of sex, stage, and B symptoms (P = .01). Impaired immune status may contribute to the development of EBV-positive cHL in older patients, and strategies aimed at boosting the immune response should be investigated in the treatment of these patients.
