RESUMEN

BACKGROUND: Patients with cancer represent an important proportion of intensive care unit (ICU) admissions. Oncologists and intensivists have distinct knowledge backgrounds, and conflicts about the appropriate management of these patients may emerge. METHODS: We surveyed oncologists and intensivists at 2 academic cancer centers regarding their management of 2 hypothetical patients with different cancer types (metastatic pancreatic cancer and metastatic breast cancer with positive receptors for estrogen, progesterone, and HER-2) who develop septic shock and multiple organ failure. RESULTS: Sixty intensivists and 46 oncologists responded to the survey. Oncologists and intensivists similarly favored withdrawal of life support measures for the patient with pancreatic cancer (33/46 [72%] vs 48/60 [80%], P = .45). On the other hand, intensivists favored more withdrawal of life support measures for the patient with breast cancer compared to oncologists (32/59 [54%] vs 9/44 [21%], P < .001). In the multinomial logistic regression, the oncology specialists were more likely to advocate for a full-code status for the patient with breast cancer (OR = 5.931; CI 95%, 1.762-19.956; P = .004). CONCLUSIONS: Oncologists and intensivists share different views regarding life support measures in critically ill patients with cancer. Oncologists tend to focus on the cancer characteristics, whereas intensivists focus on multiple organ failure when weighing in on the same decisions. Regular meetings between oncologists and intensivists may reduce possible conflicts regarding the critical care of patients with cancer.

RESUMEN

BACKGROUND: Identify in advance responder patients to chemotherapy in metastatic colorectal cancer (CRC) would allow prompt interruption of ineffective therapies in non-responder patients. Hence, predictive markers are sought in numerous trials to detect responder patients, including tumor shrinkage measured by imaging methods. Usually, Response Evaluation Criteria in Solid Tumors (RECIST) is used to evaluate tumor response in metastatic CRC, but these criteria are questionable with use of biological agents associated to chemotherapy. Our aim was correlate early metabolic response by (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography ((18)FDG-PET-CT) with long-term outcome in metastatic CRC in first-line therapy. METHODS: We prospectively evaluated 36 patients with metastatic CRC in first-line treatment with 5-fluorouracil, leucovorin (folinic acid), oxaliplatin (FOLFOX) or 5-fluorouracil, leucovorin (folinic acid), irinotecan (FOLFIRI) associated with cetuximab or bevacizumab. (18)FDG-PET-CT was performed at baseline and after two cycles of chemotherapy. The early metabolic response [standardized uptake value (SUV)] was measured to identify responder and non-responder patients and correlated with overall survival (OS) and progression-free survival (PFS). RESULTS: Median age was 58.5 years (range, 41-74 years). PFS was 15.5 months for responder and 13.3 months for non-responder (P=0.42), OS was 55.7 months for responder and not reached for non-responder. There was no correlation between delta-SUV and clinical and pathological variables analyzed. In the subgroup of patients who did not undergo resection of metastasis (45%), PFS was higher for responders (15.3×6.8 months, P=0.02). CONCLUSIONS: According to our findings, early response by (18)FDG-PET-CT was not a predictor of long-term outcome for patients with metastatic CRC treated in the first-line chemotherapy with a monoclonal antibody.
