Current status of postoperative follow-up for lung cancer in Japan: Questionnaire survey by the Setouchi Lung Cancer Study Group-A0901

Purpose: There is no recommended standard follow-up program after resection for lung cancer. Under these circumstances, each doctor establishes his or her own follow-up protocol. This questionnaire survey was conducted to grasp the current status of postoperative follow-up in Japan. Methods: The questionnaire survey was aimed at determining what examinations were performed and at what frequencies in the setting of postoperative follow-up. Based on these results, examinations performed at a frequency of >50% and the time points after resection at which they were performed were selected and presented as components of an average follow-up program. Results: Questionnaires were sent to 44 institutions, and 26 doctors responded to the questionnaire. All 26 of the doctors performed physical examinations, blood examinations, chest radiography, and computed tomography (CT) routinely, but their frequencies varied widely among the doctors. The average frequencies of the follow-up examinations as judged from this survey are as follows: Physical and blood examinations are performed three to four times a year for the first 3 years and twice a year during the next 2 years. CT is scheduled at 6 and 12 months after resection and is repeated annually thereafter. Chest radiography is performed three to four times a year for the first 3 years and once a year thereafter, between the CT examinations. Conclusion: The follow-up programs used in clinical practice vary widely among institutions and doctors in terms of the types of examination performed and the frequencies at which they are performed.
