[The Prevalence of Nontuberculous Mycobacterial Lung Disease with orwithout Reflux Esophagitis].

Background/aims: Gastrointestinal reflux disease (GERD) is defined as 'a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications'. It is associated with various lung diseases, including bronchial asthma, chronic bronchitis, and bronchiectasis. GERD may also affect nontuberculous mycobacterial (NTM) lung disease.

Most advance directives written by patients with advanced cancer or their proxies request only minimally invasive treatments during end-of-life care.

Although it is assumed that most patients with terminal cancer are reluctant to receive life-sustaining treatment, there is a paucity of evidence supporting this assumption. We retrospectively analyzed the advance directives of terminal cancer patients to determine the preferences of patients. Patients with cancer who had life expectancy of less than 6 months were admitted to a palliative care unit in Seoul Medical Center from March 2008 to February 2010.
