The studies on the QOL of gastric cancer patients mostly feature the direct interview and evaluation of patients’ symptoms or performance status by physician [
5], although the evaluation of QOL is more valuable when it is expressed by the patients themselves [
8]. Also, any study on QOL should cover as many aspects of life as possible. Kaptein et al. wrote a review on all QOL studies of patients with gastric cancer which showed that all the studies included physiological aspects but none of them included social functioning [
5]. As the biopsychosocial model of medicine is increasingly becoming significantly important, the wider spectrum QOL research is becoming increasingly valuable [

The EORTC QLQ-C30 is an extensively tested questionnaire on cancer patients which can be used to evaluate the QOL of cancer patients in any country. Furthermore, it is a combination of adequate psychometric characteristics which give an opportunity of comparing between patients with different categories of cancer [
10]. The same questionnaire was used in the studies which analysed QOL of cancer patients who followed radical surgical procedures as well [
10-
13]. The EORTC QLQ-C30 consists of 30 items which ask how the patient would rate his or her health and all the aspects associated with it during the last week [
14]. Every item belongs to a different scale or it is a single-item measure. There are five functional scales, three symptom scales, a global health status, and six single-items in the questionnaire. All of the scales and single-item measures have been transformed linearly, ranging from 0 to 100. The data was evaluated by the guidelines of the EORTC [
10,
11]. It is important to note that higher scores for the functional scales and the global health status reflect better quality of life, while high scores for the symptom scales represent problems which influence the QOL negatively.
Total curative gastrectomy consists of two phases: the removal of the stomach with a limited or extended lymphadenectomy and the reconstruction of the gastrointestinal tract. Nowadays, the most popular method of restoration of continuity of the gastrointestinal tract is Roux-en-Y one [
8]. This might be the reason why so little information on outcomes of other reconstructions as well as Omega technique can be found. The importance of knowledge on postoperative QOL as it may be an important factor in clinical decision-making, including considering surgery or not in a subgroup of patients with limited life expectancy was emphasized [
15].
Several studies analysed a relation between QOL and clinical, demographic, and social parameters as it was done in this study [
14,
16-
20]. Analysis of global health care status of our patients has shown, surprisingly, that the elder patients scored a better QOL in comparison to those younger, and is especially noticeable in social functioning. It is not simple to explain this finding of the study as other similar studies which pointed out a different trend – younger patients had better QOL after gastric surgery than older [
19,
20]. In our view, the fact that the global QOL and the social functioning was better in Lithuanian patients aged 65

years and over may be related with a less demanding, and, therefore, slightly more positive outlook to disease burden and surrounding environment. Nevertheless, one should be cautious in interpreting key finding of this study because of nature of this study. On the other hand, de Liaño et al. also indicated that older patients’ global health status was better, however, he also found that older patients had more clinical symptoms which is a contrasts to our study [
14].
Physicians often link the advanced stage of cancer with the poorer quality of life. Although the scales of the earlier-stage cases were a little bit higher, this study as well as Huang et al. study [
18] had not shown any significant differences between early and advanced cancer stages when at least 6

month had passed after surgical treatment. On the other hand, Matsushita et al. found that patients in the later stage of gastric cancer had a significantly worse quality of life [
17]. Furthermore, there is no single opinion about the influence of postoperative complications following total gastrectomy on QOL. In addition to our study, de Liano et al. stated that QOL had no relation with postoperative complications. However, Matsushita et al. concluded that it negatively influences the physical functioning of gastrectomized patients after 6

months [
14,
17]. We have to note that women had higher scores almost in all functional and symptom’s scales dimensions. Nevertheless, there were no statistically significant differences. Again, data are controversial regarding gender role on QOL [
14,
19,
21].
They are few limitations of this study. It is a retrospective study whereby there were a small number of patients responders involved; it undoubtedly caused a bias view. There was no control group. In addition to this, as the QOL is a subjective feature, it is influenced by not only diagnosis or treatment, but by the character and psychological state of the patients as well [
17].
