Section snippets
Design, Setting, and Eligibility Criteria
This study was a secondary analysis of a multicenter prospective cohort study conducted in 28 Brazilian ICUs (e-Appendix 1) between August 1 and September 30, 2007.15 The study was strictly observational, and every clinical decision (including the decision to start, change the modality, or cease the ventilatory support) was at the discretion of attending physicians. The Comitê de Ética em Pesquisa of Instituto Nacional de Câncer (No. 013/07) approved the study, as did local institutional review
Characteristics of the Study Population
Of the 717 patients admitted to the 28 participating ICUs, 263 (37%) fulfilled the eligibility criteria, and these constituted the study population (Fig 1). The median patient inclusion from each center was six (25%-75%, 4-13; range, 1-33). Two hundred twenty-seven patients (86%) had solid tumors, and 36 patients (14%) had hematologic malignancies. Ventilatory support was required more frequently by patients with hematologic malignancies (36 of 50 patients [72%]) than by patients with solid
Discussion
In the current study, we demonstrated that patients with cancer requiring ventilatory support who were admitted to ICUs may have reasonable mortality rates, especially when they have good PS and nonprogressive disease. Moreover, we determined important independent predictors of mortality in these patients, which can assist physicians in decisions relating to patients' management and the counseling of patients and families. ICU refusal of patients merely because of a cancer diagnosis is no
Conclusions
In conclusion, mortality rates in critically ill patients with cancer requiring ventilatory support remain relatively high. Patients with good PS and nonprogressive disease requiring ventilatory support should receive full intensive care, because one-half of these patients survive. On the other hand, the provision of palliative care should be considered the main goal for patients with poor PS and progressive underlying malignancy.
