Detailed Description
Patients will be recruited from the outpatient clinics of Al Monofia university hospital, Cairo University Hospital and National Cancer Institute. Patients who fits the inclusion criteria and are motivated and consent to enter the study will be included. Patient recruitment will continue until the target sample size is reached.
Patients data will be collected including personal data, medical history, family history, and classification of the tumor according to the TNM classification system. Patients will be assessed preoperatively with a transcutaneous high frequency probe ultrasound to measure the maximal tumor thickness in millimeters using a 10MHz superficial probe and the lymph nodes in the neck region. In addition to clinical examination and palpation of the neck lymph nodes. Patients will then undergo tumor resection surgery with adequate safety margins under GA with nasotracheal intubation. Selective neck dissection will then be performed. The specimens will be submitted for histopathological examination.
Patients will receive standard post operative care based on the recommendation of the oncologist. Adjunct chemo or radiotherapy will be administered when deemed necessary. Wound care and dressings will be administered as needed.
Patients will be categorized into two groups based on the tumor thickness (exposure).
For the primary outcome, the data source will be the measurement of tumor depth based on Berslow method as discussed in the review of literature, obtained from ultrasonography and recorded in millimeters.Tumor width recorded in (mm) will also be obtained from the ultrasonography as it may be a source of confounders. Further, histological grade of the lesion will also be recorded.
Two confounding factors are highlighted and may be sources of bias and attempt to control for them in the statistical analyses will be made.
Appropriate statistical methods will be used after collection of the data and sources of confounders will be controlled for during analyses in subgroup An attempt to control for tumor width and histological grade in subgroup analyses
All data will be entered electronically. Patients' files are to be stored in numerical order and stored in secure and accessible place. All data will be maintained in storage for 1 year after completion of the study. Data monitoring committee is independent from the sponsor and competing interest.
