Más betegség

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or gastritis, or psychiatric illness and social situations that would limit compliance with study requirement or compromise the ability of the subject to give written informed consent
• History of primary immunodeficiency or organ transplant requiring immunosuppressive drugs
• Patients with a known HIV, active hepatitis B or C infection
• Other invasive malignancy within 3 years except for noninvasive malignancies such as cervical carcinoma in situ, non-melanomatous carcinoma of the skin or ductal carcinoma in situ of the breast that has/have been surgically cured
• Patients with any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the study
• Severe infection requiring parenteral antibiotics treatment
• Known history or active symptomatic interstitial lung disease

Laborértékek

• Contra-indication(s) to receive high-dose cisplatin as listed in the most updated Summary of Product Characteristics (including creatinine clearance <60 mL/min, pre-existing hearing loss or neurological disorder)

An HPV-driven OPSCC is defined as a tumor that is positive for both p16 IHC and HPV-DNA ISH or PCR)
