Brief summary

The purpose of this research study is to learn about the effectiveness of using lower-intensity radiation and chemotherapy to treat human papillomavirus (HPV) associated low-risk oropharyngeal and/or unknown primary squamous cell carcinomas of the head and neck. The cure rate for this type of cancer is estimated to be high, \> 90%. The standard treatment for this cancer is 7 weeks of radiation with 3 high doses of cisplatin. Sometimes surgery is performed afterwards. This standard regimen causes a lot of side effects and long term complications. This study is evaluating whether a lower dose of radiation and chemotherapy may provide a similar cure rate as the longer, more intensive standard regimen. Patients in this study will receive 1 less week of radiation and a lower weekly dose of chemotherapy followed by a limited surgical evaluation.

Detailed description

The aim is to evaluate the pathological response rate of HPV positive and/or p16 positive low-risk oropharyngeal squamous cell carcinoma (OPSCC) after de-intensified chemoradiotherapy (CRT). Patients will receive 54 to 60 Gy of Intensity Modulated Radiotherapy (IMRT) with concurrent weekly intravenous cisplatin (30 mg/m2). Diagnostic imaging (CT and/or MRI) will be obtained 4 to 8 weeks after completion of CRT to assess response. All patients will have surgical resection of any clinically apparent residual primary tumor or biopsy of the primary site if there is no evidence of residual tumor and will undergo a limited neck dissection to encompass at least those nodal level(s) that were positive pre-treatment, 4 to 14 weeks after CRT. The primary endpoint of this study is the rate of pathological complete response (pCR) after CRT. Longitudinal assessments of quality of life and patient reported outcomes will be obtained prior to, during, and after CRT.

Interventions

All patients will receive IMRT. Dose painting IMRT will be used and all doses will be specified to the planning target volume (PTV). The high risk planning target volume (PTV-HR) and standard risk planning target volume (PTV-SR) will be treated to the following respective total doses: 60 Gy and 54 Gy. The dose per fraction to the PTV-HR and PTV-SR will be 2 Gy per day and 1.8 Gy per day, respectively. The PTV-HR will include the gross tumor and the PTV-SR will include the lymph nodes at risk for harboring micro-metastatic disease (i.e. subclinical disease).

DRUGCisplatin

Cisplatin, 30mg/m2, will be given intravenously over 60 minutes weekly during IMRT; 6 total doses for a total of 180 mg/m2. It is preferred that the doses be administered on days 1, 8, 15, 22, and 29, and 36 of IMRT; however, this is not mandatory.

PROCEDURELimited surgical evaluation

4 to 14 weeks after completion of CRT, patients will have at least a biopsy of the primary tumor and limited neck surgery to remove those lymph nodes that were involved with cancer prior to CRT.

European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 Global Health Status/QoLPrior to CRT, 4-8 weeks after CRT, follow-up visits for 2 years after CRTThe EORTC QLQ-C30 is a cancer-specific instrument with 30 questions which incorporates 9 multi-item scales: 5 functional scales (physical, role, cognitive, emotional, and social); 9 symptom scales (fatigue, pain, nausea and vomiting, dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties); and a global health and quality-of-life scale. Most questions used 4 point scale (1 'Not at all' to 4 'Very much'); 2 questions used 7-point scale (1 'very poor' to 7 'Excellent'). The scores of these scales were averaged from the scores of the component items, transformed and analyzed on a 0 - 100 scale. A higher score=better level of functioning or greater degree of symptoms.
The Eating Assessment Tool (EAT-10) Composite ScorePrior to CRT, 4-8 weeks after CRT, follow-up visits for 2 years after CRTThe EAT-10 is a 10 item, validated self-administered instrument for documenting dysphagia severity. This questionnaire uses symptom-specific scores to assess dysphasia with solids, liquids, and pills as well as the impact of dysphagia on mental, social, and physical health. Higher raw scores represent worse QoL. All items have a 0-4 scale where 0 represents no problem and 4 represents severe problem. Total score can range from 0 to 40.
The Rosenbek Penetration Aspiration ScalePrior to CRT and 4-8 weeks after completion of CRTThe Rosenbek Penetration Aspiration Scale will be used to quantify dysphagia. It is an 8-point, equal-appearing interval scale to describe penetration and aspiration events. The measure was used for thin substances, pureed substances, and solid substances. 1\. Material does not enter airway 2. Material enters the airway, remains above the vocal folds, and is ejected from the airway. 3. Material enters the airway, remains above the vocal folds, and is not ejected from the airway. 4. Material enters the airway, contacts the vocal folds, and is ejected from the airway. 5. Material enters the airway, contacts the vocal folds, and is not ejected from the airway. 6.Material enters the airway, passes below the vocal folds, and is ejected into the larynx or out of the airway. 7. Material enters the airway, passes below the vocal folds, and is not ejected from the trachea despite effort. 8. Material enters the airway, passes below the vocal folds, and no effort is made to eject.
European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-H&N-35Prior to CRT, 4-8 weeks after CRT, follow-up visits for 2 years after CRTThe head & neck cancer module of the EORTC QLQ comprises 35 questions assessing symptoms and side effects of treatment, social function and body image/sexuality. The head & neck cancer module incorporates seven multi-item scales that assess pain, swallowing, senses (taste and smell), speech, social eating, social contact and sexuality. There are also eleven single items. Most questions used 4 point scale (1 'Not at all' to 4 'Very much'); several single item questions (Pain killers, nutritional supplements, feeding tube, weight loss, and weight gain) were just coded as no=1, yes=2. The scores of these scales were averaged from the scores of the component items, transformed and analyzed on a 0 - 100 scale. For all items and scales, high scores indicate more problems (i.e. there are no function scales in which high scores would mean better functioning).

The Eating Assessment Tool (EAT-10) Composite Score

The EAT-10 is a 10 item, validated self-administered instrument for documenting dysphagia severity. This questionnaire uses symptom-specific scores to assess dysphasia with solids, liquids, and pills as well as the impact of dysphagia on mental, social, and physical health. Higher raw scores represent worse QoL. All items have a 0-4 scale where 0 represents no problem and 4 represents severe problem. Total score can range from 0 to 40.

Time frame: Prior to CRT, 4-8 weeks after CRT, follow-up visits for 2 years after CRT

The Rosenbek Penetration Aspiration Scale

The Rosenbek Penetration Aspiration Scale will be used to quantify dysphagia. It is an 8-point, equal-appearing interval scale to describe penetration and aspiration events. The measure was used for thin substances, pureed substances, and solid substances. 1\. Material does not enter airway 2. Material enters the airway, remains above the vocal folds, and is ejected from the airway. 3. Material enters the airway, remains above the vocal folds, and is not ejected from the airway. 4. Material enters the airway, contacts the vocal folds, and is ejected from the airway. 5. Material enters the airway, contacts the vocal folds, and is not ejected from the airway. 6.Material enters the airway, passes below the vocal folds, and is ejected into the larynx or out of the airway. 7. Material enters the airway, passes below the vocal folds, and is not ejected from the trachea despite effort. 8. Material enters the airway, passes below the vocal folds, and no effort is made to eject.

Time frame: Prior to CRT and 4-8 weeks after completion of CRT
