She presented to the emergency room with stridor, cervical swelling, and breathing difficulties for over 2 days.

Hypoglycemia usually presents in the late stage of the disease and indicates a poor prognosis. This case series displays the characteristics profile of patients with primary and secondary liver cancer who are presented with hypoglycemia in a tertiary referral hospital in Indonesia. The study included 41 liver cancer patients who were presented with hypoglycemia. Hepatocellular carcinoma was diagnosed in 51.2% of patients, metastatic liver disease in 14.6% of patients, and undiagnosed liver cancer in 34.1% of patients. The mean age was 47.7 years with male predominance (65.9%). Jaundice was found in 58.5% and hepatomegaly in 70.7% of patients. The mean (± S.D.) initial blood glucose was 42.15 ± 17.11 mg/dL and the Child-Pugh score was 9.93 ± 2.11. Based on imaging, tumor diameter was 12.6 ± 6.9 cm, multiple (61%), and involving both lobes (61%). Treatments for hypoglycemia included oral/enteral feeding, intravenous dextrose, and steroids. No treatment was given for the cancer because all patients were in an advanced stage. The treatment resulted in 41.5% blood glucose being controlled, 56.1% refractory, and 2.4% persistent. Mortality was 70.7% and in average occurred 5.76 ± 4.99 days after hypoglycemia. The mainstay of treatment in these cases is treating the tumor with cytoreduction.

Hypoglycemia is often caused by islet cell and non-islet cell tumors, with a higher occurrence in non-islet cell tumors due to paraneoplastic syndrome and the high metabolic requirements of the tumor. The mainstay of NICTH treatment is treating the tumor with cytoreduction. However, in an advanced stage, cytoreduction therapy is often challenging to conduct. Beneficial supportive treatments for controlling blood glucose are frequent meals, dextrose infusion, and the injection of steroids and glucagon.
