Cancer treatment and management for elderly patients 80 years of age or older with malignant solid tumors

We retrospectively analyzed the backgrounds, treatment and nursing care for 96 patients aged 80 years or more with malignant tumors. Twenty of them were hospitalized on an emergency basis. Sixty patients were male and 36 were female, with a median age of 83 years (range: 80-94 years). Twenty-seven had a PS of 3 or 4, and 41 were rated as not independent based on analysis of autonomy at hospitalization. Forty-seven patients had clinical stage III or IV malignancies. The proportions of patients with disease complications were 33.3% for neurological disease, 21.9% for respiratory disease, 70.8% for cardiovascular disease including hypertension, and 36.5% for metabolic disease. Thirty-nine patients underwent surgical or endoscopic resection of their tumors. Twenty-three patients received chemotherapy: hormonal treatment in 14, local injection of cytotoxic agent(s) in 6 and systemic anti-cancer therapy in 3. Thirty-nine patients received supportive care only. Forty-three patients newly required nursing care or an increased level of care at discharge. The median survival time was 10.9 and 15.3 months for stage III/IV and 0/I/II patients, respectively. In conclusion, most elderly patients with malignant tumors require full supportive care, including social nursing care, from the time of cancer diagnosis.
