Postoperative radiochemotherapy is indicated in patients with multiple lymph node metastasis, lymph node metastasis with extracapsular spread and / or residual tumor (R1-Status) after resection. Oropharyngeal cancer caused by HPV (human papillomavirus 16) is a distinct subgroup with a known sensitivity to radiotherapy (RTx) or radiochemotherapy (RCTx). Additionally a superior outcome after R(C)Tx over HPV negative patients was shown for patients treated with primary or adjuvant RCTx. To date it is unknown if the total dose of the radiotherapy can be safely reduced with the aim to decrease the therapy associated late effects.\n\nPatients with a HPV associated carcinoma that take part in the study will be treated with a reduced radiotherapy dose, chemotherapy will be prescribed based on clinical factors (number of affected lymph node, presence of extracapsular spread or residual tumor). Radiation dose will be reduced in two steps.', 'detailedDescription': 'For all patients taking part in the study the HPV status of the resected tumor will be determined centrally by p16 immunohistochemistry and confirmation will be done by HPV DNA assessment using Polymerase Chain Reaction (PCR)-based array. Patients positive for HPV will be treated with a reduced RT dose to the tumor and to elective neck. HPV negative patients will be treated with standard radio- or radiochemotherapy. Patients deemed at high risk for locoregional recurrences (presence of extracapsular spread, residual tumor or multiple affected nodes) will be treated separately from patients deemed at intermediate risk (T\\>=3, and / or 1-3 nodes positive). The high risk group will be treated with a higher dose and concurrent chemotherapy. After inclusion of 30 patients per treatment group, follow up for the first 10 patients of the of the first de-escalation level will be awaited for two years and safety of the intervention will be assessed. The second de-escalation level will only be opened for accrual if less than 2 locoregional recurrences will occur within the first 10 patients per treatment group.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Condition after surgical removal of a squamous cell carcinoma of the oropharynx and adequate lymph node dissection\n* Indication for adjuvant radiotherapy or radiochemotherapy in the interdisciplinary tumor board\n* Good general state (ECOG performance status 0 or 1)\n* Adequate compliance to ensure closely follow-up\n* Patient's consent and written consent\n* Neck dissection of at least the tumor bearing side\n\nAdditional Inclusion Criteria Arm intermediate risk (at least one of the criteria must be fulfilled):\n\n* pT3 and R0 and / or\n* histologically confirmed involvement of lymph nodes (n = 1-3) and no extracapsular extension of the lymph node metastasis\n\nAdditional Inclusion Criteria Arm high risk (at least one of the criteria must be fulfilled):\n\n* residual tumor (R1 status) and / or\n* pathologic stage T4 (pT4) status and / or\n* more than 3 infected lymph nodes and / or\n* extracapsular extension of at least one lymph node metastasis\n\nExclusion Criteria:\n\n* Patients with a cumulative nicotine abuse \\> 30 packyears.
