Factors Sustaining Tobacco Abstinence in Cancer Patients Treated With Radio-chemotherapy or Radiotherapy

A Prospective Study on the Factors Sustaining Tobacco Abstinence in Patients Treated With Radio-chemotherapy or Radiotherapy Alone for Head and Neck or Lung Cancer

The TABAC STOP ORL POUMON study aims to evaluate the factors influencing long-term smoking cessation in patients with head and neck cancer (HNC) or lung cancer undergoing radiotherapy or chemoradiotherapy. This is a single-center observational study, following patients at 1, 6, and 12 months after treatment completion. The primary objective is to determine the proportion of abstinent patients at 6 months, while secondary objectives analyze factors influencing abstinence, smoking trajectories, and reasons for relapse. A total of 100 patients will be included to ensure robust statistical analysis.

The TABAC STOP ORL POUMON study is a prospective, single-center observational study aiming to understand factors influencing long-term smoking cessation in patients treated for head and neck or lung cancer. Tobacco is a leading cause of death and disease, particularly in areas like Hauts-de-France with high smoking rates.

Eligible patients, undergoing radiotherapy or chemoradiotherapy, are enrolled during the final week of treatment, completing questionnaires assessing nicotine dependence and alcohol use. Follow-ups are scheduled at 1, 6, and 12 months, through clinic visits or phone interviews.

The primary endpoint is the proportion of patients who remain smoke-free at 6 months. Secondary endpoints include factors influencing smoking cessation, reasons for relapse, and changes in nicotine and alcohol dependence. The study will enroll 100 patients, expecting 81 evaluable cases, with data quality ensured through regular checks and source verification.
