Nasopharyngeal carcinoma (NPC) is a type of head and neck cancer. The last three decades of research in head and neck radiation oncology have largely focused on improvements in survival, which have mostly come at the cost of long term toxicity for surviving patients. This is an observational study that is being done to learn about the long-term symptoms and side effects that survivors of nasopharyngeal cancer may have following radiation treatment. This study will include assessment of patient report outcomes, physician-graded adverse events, neurocognitive assessment and endocrine and hearing testing
This study is designed to provide comprehensive cross sectional information on the late toxicities following radical chemoradiotherapy in nasopharyngeal carcinoma in patients who are disease free with a minimum of four years follow-up and who were treated with contemporary radiotherapy techniques (IMRT). This is an observational cross-sectional study which will aim to define the late effects in this population, investigating both well known toxicities identified from studies using earlier radiotherapy techniques (2D and 3D radiotherapy) as well as toxicities which have not been well defined in the current literature and which may be under-recognized and under treated (pituitary function and neurocognitive outcomes). This study will assess survivors at a single time point four years after completion of their treatment who are disease free. This comprehensive review will include demographic data, clinical assessment, biochemical assessment of hormonal (pituitary and thyroid) function, patient reported outcomes, and quality of life and neurocognitive questionnaires. This study will attempt to comprehensively review these toxicities in a contemporary patient group with modern radiotherapy techniques in an attempt to bridge the gap between current recommended follow up protocols and the actual challenges faced by long term survivors. Some of these factors will be correlated with radiation doses received by the patient to inform on radiation dose thresholds for appropriate toxicities (hypothalamic-pituitary, thyroid, temporal lobe necrosis, neurocognitive performance). Patients will be offered follow-up, if required with appropriate personnel if appropriate, including neuropsychology, endocrinology and otoloryngology.

University Health Network, Princess Margaret Cancer Centre
Toronto, Ontario, Canada
Evaluation of late toxicities( will be measured using CTCAE v 4.0 criteria)
• Clinical toxicities will be grade according to Common Terminology Criteria for Adverse Events version 4.03 (CTCAE v4.03), a well known toxicity grading scale from 0 (asymptomatic) to 5 (death).
Time frame: 1 Year
Serum Biochemical Tests for Endocrine Function (fT4, TSH)
* A single blood test (at same time as the pituitary assessment) will include free thyroxine (fT4; units pmol/L), Thyroid-Stimulating Hormone (TSH; units mIU/L), * Biochemical serum deficiencies in morning testing will be scored individually according to CTCAEv4.03
Time frame: 1 Year
Quality of Life Questionnaires: Functional Assessment of Cancer Therapy (FACT-G, FACT-HN)
* Quality of life as measured by Functional Assessment of Cancer Therapy-Head \& Neck (FACT-HN) and FACIT-Fatigue ranking individual items from 0= not at all to 4 = very much. * An overall score is reported on the sum of individual items. The FACT-HN consists of the FACT-G (which consists of 27 questions from physical, social, emotional and functional domains) and a 12-item specific head and neck module. A maximum score for the FACT-HN of 144 reflects the best possible quality of life.
Time frame: 1 Year
Quality of Life Questionnaires: Functional Assessment of Chronic Illness Therapy-Fatigue (FACT-Fatigue)
A 13-item specific questionnaire scored using individual items from 0= not at all to 4 = very much collated for a total score.
Time frame: 1 Years
Quality of Life Questionnaires: Utilities Assessment (EuroQoL - EQ-5D)
A standardized self-reported utility instrument consisting of 5 discrete, 3-level items, and a visual analog scale
Time frame: 1 YEAR
Quality of Life Questionnaires: Symptom Burden of Treatment (MD Anderson Symptom Inventory-Head Neck)
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
• A patient-reported outcome instrument consisting of 28 items, 19 related to common and severe symptoms experienced by cancer patients and 9 specific to head and neck, rated from 0=not present to 10=as bad as you can imagine
Time frame: 1 YEAR
Quality of Life Questionnaires: Assessment of Depression and Anxiety (Hospital and Anxiety Depression Score)
A 14 question item scale (7 Anxiety and 7 depression) score 0-3 (each item is individually written) for individual anxiety and depressions scores from 0-21 with validated cut-off points
Time frame: 1 YEAR
Assessment of Frontal Lobe Behavior (Frontal Systems Behaviour Scale)
A validated self-rating scale designed to measure the three frontal systems behavioral syndromes: apathy, disinhibition, and executive dysfunction. A 46-item questionnaire rated pre- and post treatment is scored 1=almost never to 5= almost always. Summary scores are calculated and converted to t-scores.
Time frame: 1 YEAR
Cognitive Assessment (Montreal Cognitive Assessment - MoCA)
A short cognitive assessment testing several cognitive domains - visuospatial, naming, memory, attention, language, abstraction, delayed recall and orientation. A maximum score is 30.
Time frame: 1 YEAR
Association of Radiation Dose with Temporal Lobe Necrosis
Dose Volume Histograms (DVHs; quantitative radiation dose data delivered to specific organs) will be calculated from initial radiotherapy plans to review association between dose received by the temporal lobe and risk of temporal lobe necrosis.
Time frame: 1 Year
Association of Radiation Dose with Hearing Loss
Dose Volume Histograms (DVHs; quantitative radiation dose data delivered to specific organs) will be calculated from initial radiotherapy plans to review association between dose received by the cochlear and vestibulocochlear nerve and risk of hearing loss
Time frame: 1 Year
Association of Radiation Dose with Cognitive Impairment
Dose Volume Histograms (DVHs; quantitative radiation dose data delivered to specific organs) will be calculated from initial radiotherapy plans to review association between dose received by the temporal lobe, brain and hippocampus and risk of neurocognitive impairment.
Time frame: 1 Year
Association of Radiation Dose with Pituitary Dysfunction
Dose Volume Histograms (DVHs; quantitative radiation dose data delivered to specific organs) will be calculated from initial radiotherapy plans to review association between dose received by the pituitary and risk of hypopituitarism
