A survey on pulmonary screening practices among otolaryngology-head & neck surgeons across Saudi Arabia in the post treatment surveillance of head and neck squamous cell carcinoma: Cross sectional study . (Preprint)
BACKGROUND In head and neck squamous cell carcinoma patients (HNSCC), post treatment surveillance for distant disease is mostly focusing on the lungs, as HNSCC distant metastasis occurs in this organ in 90% of the cases and a high rate of primary of the lungs can be expected due to field cancerization of the entire upper aero digestive tract. OBJECTIVE The survey aimed to evaluate the current beliefs and pulmonary screening practices among otolaryngology-head & neck surgeons across Saudi Arabia in the post treatment surveillance of head and neck squamous cell carcinoma. METHODS This is a nation-wide cross sectional survey was conducted among Head and Neck surgeon members of the Saudi Society of Otolaryngology. Data Collected During The Period From 1– 30 July , 2020. Predesigned questionnaire including all the relevant questions to fulfill the study objectives. Questions inquired about characteristics of routine lung screening during the post treatment follow-up of head and neck cancer. The questionnaire distributed on all head and neck surgeon of the Saudi Society of Otolaryngology, of Saudi Arabia. RESULTS As regards the methods of routine lung screening during the post treatment follow-up of head and neck cancer, our study found that the majority 40% 9 out of 22 participants used lung radiography followed by 31% 7 out of 22 participants used low dose CT and 27 % 6 out of 22 participants used PET/CT. Regarding to duration of lung screening in head and neck cancer during follow up in physician's practice, the majority 77 % 17 out of 22 participants reported 5 years, 13% 3 out of 22 participants 10 years and only 9 % 2 out of 22 participants performed lung screening lifelong. As regards frequency of lung screening; 77 % 17 out of 22 participants reported annually screening,18% 4 out of 22 participants half-yearly and 4% 1 out of 22 participants biennially. According to believed effectiveness of the screening procedures listed in question 1 in reducing lung cancer mortality during the follow-up of head and neck cancer; 6% 8 out of 22 participants believed to be very effective or somewhat effective, 18% 4 out of 22 participants don’t know and only 9% 2 out of 22believed that it was not effective. CONCLUSIONS The majority used lung radiography, low dose CT and PET/CT as a routine lung screening during the post treatment follow-up of head and neck cancer for mainly 5 years, 10 years and only small percent performed lung screening lifelong. lung screening was mostly annually or half-yearly. The screening believed to be very effective or somewhat effective.
