Eligibility

Sex/Gender
Male
Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: 1. Male patients who aged 18 years old or older at OPC diagnosis 2. Patients who were diagnosed with first primary OPC which identified by specific list of cancer ICD-10 in the time-period from January 2021 to December 2025 3. Patients with an available untreated biopsy or resection tissue sample of oropharynx which obtained as part of regular clinical practice procedures for OPC diagnosis or clinical management 4. Patients who are willing to provide written informed consent, if required per site regulations 5. The tumor tissue specimen should be adequately preserved in formalin (preferably fixed in neutral, buffered-formalin) and embedded in paraffin 6. The paraffin blocks should be appropriate size to allow good fixation and permit re-cutting

Exclusion criteria

Exclusion criteria: 1. Patient whose tumor is classified as C14 (pharynx, unspecified), based on ICD-10 classification 2. Patients for whom only fine needle aspiration samples from metastatic lymph nodes are available 3. Patients with low quality tissue samples that do not allow an appropriate assessment of HPV test 4. Patients for whom histopathological examination on hematoxylin and eosin sections does not confirm the presence of invasive cancer

Design outcomes

Primary

MeasureTime frame
HPV-attributable fractions in OPC Single timepoint Proportion of OPC cases classified as HPV-attributable, defined by positivity for both HPV DNA testing and p16INK4a IHC

Secondary

MeasureTime frame
Distribution of HPV genotypes Single timepoint Proportion of each HPV genotype among HPV-attributable cases, determined using a validated HPV DNA genotyping assay,Characteristics of patients included in the study Single timepoint Collection of information from medical records
