Retrospective analysis of lung cancer patients treated with supportive care alone.

Background: It is not uncommon for patients with lung cancer to receive supportive care alone. However, the clinical characteristics of these patients have not been fully studied. We conducted a retrospective study to identify the clinical characteristics of definitive lung cancer patients treated with supportive care alone.

Methods: We retrospectively analyzed the percentage of and reasons for definitive lung cancer patients treated with supportive care alone at a regional cancer center. We also investigated the histological diagnostic approaches, palliative therapy types, primary treatment locations after hospital consultation, and places of death.

Results: A total of 1,223 patients were histologically diagnosed as having lung cancer between 2011 and 2014. Of these, 160 (13%) patients were treated with supportive care alone. The primary reason for treatment with supportive care alone was a poor performance status (PS) in almost half of the patients. Overall, 40% of the patients received supportive care at home, and 17% were admitted to a palliative care unit (PCU). Death occurred at home for 17% of the patients and in the PCU for 42% of the patients.

Conclusion: This study revealed that 13% of histologically proven lung cancer patients were treated with supportive care alone, mostly because of a poor PS. Only 40% of these patients received home care, suggesting the need for a more accessible home care system for patients and their families.
