[The option of critical patients with cancer for ICU].

With the improvement of diagnosis and treatment, tumor has become a chronic disease, and an increasing number of older patients will live with tumors. This change has led to an increase in demand for intensive care unit (ICU) and a challenge to the traditional ICU treatment concept. The option of ICU consists of two parts. The first is the option for admission. Since classic predictors of mortality are no longer relevant, we suggest broadening the criteria for ICU admission. Patients during the first course of cancer therapies should be treated with a full-code status similar to that of other patients without malignancy. Patients whose clinical response to therapy was not available or undetermined should be allowed an ICU trial that consists of unlimited invasive support, including anti-cancer therapies such as ambulatory chemotherapy. Do everything that can be done to save the patients who might benefit from ICU treatment. The second is the option of therapeutic end point. An interdisciplinary meeting, including an ethics consultation, should be held after 3-6 days'ICU trial to make end-of-life decisions with relatives of patients if the SOFA score shows clinical deterioration with no available therapeutic options. The treatment goals should shift from curative or supportive therapies to end-of-life care. we could integrate hospice and palliative care with intensive care more effectively and efficiently. That would be the future of oncological ICUs.
