Objective
Gastrointestinal stromal tumours are tumours of
mesenchymal origin that can be located along
the gastrointestinal tract. In this study, the role of
Modified systemic inflammation score in predicting
the prognosis of these tumours was investigated.
Material and Method
115 patients diagnosed with Gastrointestinal Stromal
Tumor (GIST) who underwent surgery at Ankara City
Hospital between June 1, 2019 and December 1,
2022 were examined. Tumor location, size, presence
of rupture-bleeding-necrosis, Ki-67 level, mitotic index
and preoperative albumin, lymphocyte and monocyte
levels were evaluated. mSIS score was grouped as
0, 1 and 2. The relationship between mSIS and Ki-
67 index and the presence of rupture, necrosis and
bleeding was investigated.
Results
Out of 115 patients, 68 (59 %) were male, 47 (41 %)
were female, with an average age of 62.5 (± 12.67)
years. Tumor locations: stomach (64.3 %), small
intestine (26 %), colon (5.2 %), esophagus (1.8 %),
pancreas (1.8 %), and ovary (0.9 %). Necrosis was
in 25 (30.7 %), hemorrhage in 67 (58.7 %), rupture
in 19 (16.8 %), and the mean Ki-67 level was 9.09 (±
10.64). 63 (54.8 %) patients had mSIS 0, 29 (25.2 %)
had mSIS 1, and 23 (20 %) had mSIS 2. Statistical
analysis found a significant correlation between mSIS
and necrosis, but not with other parameters.
Conclusion
The mSIS score is a valuable score showing
inflammation in the body and has been shown to be
associated with the prognosis of many malignancies.
In our study, the presence of necrosis in the tumour
was found to be associated with the mSIS score.
Although this result alone is not sufficient to predict
the prognosis, it is thought to be an issue that may
open the door to new studies.
