Study on blood ammonia in terminally ill cancer patients

ABSTRACT

<b>Purpose：</b>Although ammonia shows a high due to advanced liver failure and the development of portal vein collateral circulation, there are few reports on ammonia in terminal stage of cancer. Therefore, the blood ammonia was measured against terminally ill cancer patients were studied retrospectively. <b>Methods：</b>For 80 cases who were admitted to the hospital for the purpose of palliative care, measured the blood ammonia at the time of admission, we have studied cancer species, gender, age, survival period, HbA1c, albumin, aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, blood urea nitrogen, prothrombin activity, estimated glomerular filtration rate, C-reactive protein, hematocrit, presence or absence of liver metastases, presence or absence of opioid, laxative use, L3 level psoas major muscle area in ammonia high-value group and the normal group. <b>Results：</b>Hyperammonemia in terminally ill cancer patients in average survival time 41.6 days was observed in 21.3％. The significant differences in gender and liver metastasis in univariate analysis, liver metastases were extracted in the logistic regression. <b>Conclusion：</b>Cancer terminally ill patients with liver metastases were significantly higher to exhibit hyperammonemia in this study.
