This study included patients with upper gastrointestinal hemorrhage who were treated in intensive care unit of GATA Haydarpasa Training Hospital, Division of Internal Medicine during 1 year. Medical and demographic data of the patients were recorded. These patients were followed for 3 months after being discharged from the intensive care unit. Of the 50 patients in the study, 18 were female (36%), 32 were male (64%). The mean age was 47±2 years, and the ages ranged between 17 and 89 years. We did not find any statistically significant results in our evaluation of the relationship between the mean platelet volume and the number of transfusions, endoscopic findings, and prognosis after 3 months of follow-up.

The interaction between cancer cells and platelets has been known for a long time. Although platelet indices have been also investigated in several clinical settings, it has not been exactly demonstrated in cancer patients. We investigated platelet indices in colorectal cancer patients and compared with healthy subjects. Two hundred and twenty-one colorectal cancer patients and 110 healthy subjects were enrolled into the retrospective study. Data were obtained from computerized medical records of our hospital. Medical record review was performed for all patients regarding thrombocyte indices. Platelet count (325.000/mm3 ± 265.000/mm3 vs 267.000/mm3 ± 67.000/mm3; p=0.025; respectively) and plateletcrit (Pct) (0.25% ± 0.10 vs 0.21 ± 0.05; p<0.001; respectively) were increased in patients compared with healthy subjects while mean platelet volume (MPV) and platelet distribution width (PDW) were similar. The platelet indices were not related to existence of metastasis or acute abdomen. Platelet count and Pct, but not MPV and PDW, are elevated in colorectal cancer patients. Future studies that investigate platelet morphology, function, and putative role of platelets in tumorigenesis and metatasis should be established.
