The Voice as a Tool to Detect Recurrence of Laryngeal and Hypopharyngeal Cancer (VoiceDetect) - a Feasibility Study
The investigators will obtain three-monthly voice recordings and fiberendoscopic examinations of the larynx/hypopharynx for a minimal period of 6 months from all laryngeal/hypopharyngeal squamous cell carcinoma (LSCC/HPSCC) patients, who have successfully completed curative primary treatment, except those who underwent total laryngectomy. Furthermore, the investigators will ask the patients to fill out the voice handicap index-30 questionnaire (VHI-30) during each study visit. The VHI-30 allows to make a subjective assessment of the patients' own vocal problem. The primary objective is to assess the feasibility and compliance of longterm regular voice monitoring in LSCC and HPSCC follow-up.
• Histopathologically proven carcinoma in-situ or invasive LSCC or HPSCC (in non-surgically treated carcinoma: clinical/radiologic stage I-IV (excluding M1) according to the Union for International Cancer Control (UICC) / Tumor (T), Nodes (N), and Metastases (M) (TNM) 8th ed.; in surgically treated carcinoma: pathological stage I-IV (excluding M1) according to the UICC / TNM 8th ed.).
• ≥ 18 years of age.
• Treatment with curative intent, regardless of treatment modality (mono- or multimodal).
• Remark: Patients with synchronous (larynx and hypopharynx included) or metachronous (before/after the diagnosis of LSCC/HPSCC) non-laryngeal/-hypopharyngeal malignant non-metastatic tumors, with clinically confirmed complete remission 6 months after treatment and life expectancy of at least 6 months are eligible. Patients with surgically treated Tis-2 N0 M0 squamous cell carcinoma and/or basal cell carcinoma of the skin and/or other surgically treated non-head and neck Tis are eligible, although the treatment was within the 6 months before enrolment.
• Clinical confirmation of complete remission of LSCC or HPSCC through Ear, Nose and Throat (ENT) examination, including fiberendoscopy of the pharynx and larynx, at the time of enrolment, during the period of eligibility (6 to 30 months after treatment).
• Remark: Patients with synchronous (larynx and hypopharynx included) or metachronous (before/after the diagnosis of LSCC/HPSCC) non-laryngeal/-hypopharyngeal malignant non-metastatic tumors, with clinically confirmed complete remission 6 months after treatment and life expectancy of at least 6 months are eligible. Patients with surgically treated Tis-2 N0 M0 squamous cell carcinoma and/or basal cell carcinoma of the skin and/or other surgically treated non-head and neck Tis are eligible, although the treatment was within the 6 months before enrolment.
