1) Radiotherapy:
Radiotherapy is a primary treatment modality for nasopharyngeal carcinoma (NPC) across all stages of the disease. It uses high doses of radiation to target and destroy cancer cells, typically achieving excellent locoregional control. Proper planning is crucial to minimize side effects on adjacent healthy tissues, like the brain and spinal cord.

2) Disease:
The term disease refers to the pathological condition affecting nasopharyngeal tissue in NPC. Late presentation of the disease results in poor prognosis and mortality, emphasizing the necessity for early detection and a high index of suspicion in clinical assessments. Timely diagnosis can significantly improve treatment outcomes for affected patients.

3) Cancer:
NPC is a type of cancer that occurs in the epithelial lining of the nasopharynx. While rare globally, it represents a significant health concern in Southeast Asia and among Southern Chinese populations. Understanding the characteristics and behavior of this cancer is essential for effective treatment and management strategies.

4) Chemotherapy:
Chemotherapy plays a critical role in the management of advanced NPC with locoregional disease. It is often combined with radiotherapy to enhance treatment efficacy and improve survival outcomes. Various agents, including cisplatin and 5-fluorouracil, are utilized based on individual patient conditions and cancer staging.

5) Study (Studying):
Numerous studies have aimed to enhance the understanding of NPC, its clinical presentations, and treatment effectiveness. These studies provide essential data regarding patient outcomes, prognostic factors, and potential biomarkers, like circulating free Epstein-Barr virus DNA, which have implications for monitoring disease progression and treatment response.

6) Sam (Sām, Sham, Śam):
Sham is related to Wei Wei Sham, a leading figure in NPC research. In various studies, his work has greatly contributed to the advancements in surgical techniques, including the maxillary swing approach for nasopharyngectomy. Such technical developments improve outcomes for patients with recurrent or residual NPC.

7) Viru (Vīṟu):
The term relates to viral factors in NPC, particularly the Epstein-Barr virus (EBV), which has been implicated in disease pathogenesis. EBV presence can be detected for diagnostic purposes and is correlated with NPC stages. Its role highlights the intersection between infectious agents and cancer development.

8) Nature:
Nature refers to the diverse clinical presentations that NPC can exhibit, complicating diagnosis and treatment. The tumor's nature, including its ability to present submucosally, often leads to late detection. Understanding these characteristics is vital for clinicians to recognize symptoms and facilitate early interventions.

9) Surrounding:
Surrounding structures are critical in evaluating NPC due to the close proximity of vital organs and tissues to the nasopharynx. Radiation therapy protocols must consider these surrounding areas to minimize damage. Understanding these anatomical details enhances treatment planning and patient safety during therapeutic interventions.

10) Deafness:
Deafness is a common symptom associated with NPC due to eustachian tube obstruction caused by tumor growth. It can affect a patient's quality of life significantly, leading to communication difficulties. Awareness of such neurological symptoms assists clinicians in early identification and subsequent management of NPC.

11) Quality:
Quality of life is an important consideration for NPC survivors, as treatments often result in long-term complications including neurological issues and cognitive dysfunction. Addressing quality of life post-treatment has become crucial, influencing treatment choices to mitigate adverse effects and enhancing overall patient well-being.

12) Rampal (Rāmpāl):
Rampal is associated with research that explores diagnostic aids for NPC. His contributions to understanding the clinical features and epidemiology of NPC are instrumental in promoting awareness and facilitating the detection of the disease at earlier stages for better patient management outcomes.

13) Chang:
Chang pertains to studies involving diagnostic methods and treatment assessments in NPC. This includes understanding how specific biomarkers and diagnostic approaches, including EBV serology, can facilitate early disease detection, influencing treatment pathways and improving prognostic evaluations for affected patients.

14) Field:
Field refers to the radiotherapy treatment fields employed in NPC management. Proper delineation of treatment fields is crucial to ensure that the tumor is adequately targeted while sparing surrounding normal tissues. Effective field planning can improve treatment efficacy and minimize radiation-induced complications.

15) Life:
Life refers to the health-related quality of life of NPC patients post-treatment. Long-term survivors often face challenges due to the late complications of treatment, necessitating a multi-disciplinary approach to care that prioritizes both oncological control and overall well-being of patients.

16) Post:
Post refers to the timing after initial treatment where ongoing monitoring of NPC patients is critical, especially concerning recurrence and residual disease. Methods such as measuring EBV DNA provide valuable insights into post-treatment status and can guide subsequent care and management strategies.

17) Chan (Chaṇ, Chaṅ):
Chan is associated with studies linking plasma EBV DNA levels with NPC prognosis. This research has highlighted the importance of EBV DNA quantification in understanding disease progression and treatment outcomes, which is crucial for tailoring follow-up and surveillance strategies in NPC patients.

18) Blindness:
Blindness can occur in NPC due to cranial nerve involvement or direct spread of cancer, affecting patients' vision and quality of life. Recognizing visual symptoms early can aid in diagnosing NPC and improving patients' overall management as part of a comprehensive treatment plan.

19) Fixation:
Fixation of neck nodes is a significant prognostic factor for NPC outcomes. The degree of fixation is indicative of the disease's aggressiveness. Understanding these characteristics during diagnosis allows better staging and treatment planning, ultimately influencing patient prognosis.

20) Humana (Humaṇa):
Humana refers to a publishing entity that has documented studies on NPC, contributing to the scientific discourse surrounding the disease. Their publications have aided in disseminating knowledge about diagnosis, treatment methodologies, and historical perspectives on managing NPC effectively over the years.

21) Reason:
Reason encompasses the various factors leading to late presentation of NPC, including symptomatology confusion and patient reluctance to seek medical attention. Identifying these reasons is crucial for developing strategies aimed at increasing awareness and promoting early intervention in susceptible populations.

22) Filling (Filled):
Filled refers to surgical approaches where abnormalities within the nasopharynx are addressed, often employing grafts or muscle flaps to fill surgical defects post-tumor resection. This aspect of surgical treatment is vital for restoring function and aesthetics following aggressive tumor removal.

23) Blood:
Blood investigations play an important role in supporting the diagnosis of NPC, particularly through indicators like full blood count and erythrocyte sedimentation rate (ESR). Such laboratory tests can reveal underlying health concerns, guiding clinicians in comprehensive patient management strategies.

24) Maran (Māraṉ, Maraṇ, Māṟaṉ):
