Quality of Life in Patients With Lung Cancer: Materials and Methods

Two methods of investigations were carried out: a MEDLINE search and a manual search through published articles from 1970 to 1995. The year 1970 was chosen because the first study (to our knowledge) of quality of life in patients with lung cancer was published in 1970. For the MEDLINE search, the key words “quality of life” and “lung cancer” were used. This provided the initial database for the review. The initial search was carried out in 1994 and updated twice in 1995 and once at the end of January 1996. Causes bronchiolitis
In the second procedure, using the initial database, the articles cited in the literature were examined for possible additional existing articles. There were no specific criteria for inclusion of articles in the review, but they were excluded if the language was not English. A similar method of investigation in reviewing quality of life in patients with ovarian cancer was used.
Results
A total of 151 citations were identified and reviewed. Of these, 48 citations were in abstract form and there were studies that appeared both in an abstract form and in a complete publication form. This means that some studies were counted twice (once in an abstract form and once in form of a complete publication). In addition, there were identical studies from the same author(s) that have been published in different stages of the studies or with different findings. These were also counted as many times as they appeared in the literature.
Of 151 citations, 68 were not restricted to specific cell type of lung cancer (47 citations on quality of life in lung cancer patients in general, and 21 citations on quality of life in cancer patients including that of lung). The remaining 83 citations were restricted to define samples of small or non-small cell lung cancer patients (41 citations on quality of life in patients with small cell lung cancer and 42 studies of nonsmall cell lung cancer).
However, of 151 citations, 30 were validation studies and 3 were feasibility studies. The rest were studies with different objectives, including clinical trials with survival time and quality of life as end points, and descriptive studies measuring clinical outcomes.
