[ICU admission for cancer patients with respiratory failure: An ethical dilemma]. / Admission aux soins intensifs du patient cancéreux avec une atteinte respiratoire : un dilemme éthique.

In medicine, each decision is the result of a trade-off between medical scientific data, the rights of individuals (protection of persons, information, consent), individual desires, collective values and norms, and the economic constraints that guide our society. Whether or not to admit a cancer patient to an intensive care unit is very often an ethical dilemma. It is necessary to distinguish patients who would benefit from admission to an intensive care unit (ICU) from those for whom it would be futile. In this review, we will discuss the appropriateness of ICU admission and the concept of unreasonable admission, along with the different levels of intensity of ICU care and the alternatives to intensive care. We will then consider how and when to initiate reflection leading to a reasonable decision for the patient.

Quels malades peuvent et doivent aller en réanimation ?: Which patients can and should go to intensive care?

When a lung cancer patient develops an organ failure, the intensity of the care should be decided taking into account patient's wishes and his plan of carekeeping, in mind that the objective of an intensive care unit (ICU) admission is to allow the patient to be discharged from ICU and hospital with an acceptable quality of life. But the physician in charge of the patient at the time of acute disease often does not have these information. It is therefore essential that the referring oncologist had an early discussion with the patient to inform him and collect his opinion. These information have to be noted in the patient's medical chart. The prognostic criteria of lung cancer patients admitted in ICU are related to the patient's characteristics, the cancer's characteristics and the severity of acute disease. In order that a decision of ICU admission is in accordance with the patient's therapeutic project, a close discussion between the oncologist and the intensivist is essential, especially in this period of SARS-CoV2 pandemy.© 2021 SPLF.

Do systemic treatments delivered after Nivolumab result in better outcomes? A bicentric case-control study.

BACKGROUND: Immune checkpoint inhibitors (ICI) are now widely used at different stages of non-small cell lung cancers (NSCLC). Some clinical studies suggest that chemotherapy and immunotherapy have synergic activities, raising the question of the best therapeutic sequence. We studied the effect of chemotherapy in advanced NSCLC when administered after immunotherapy by nivolumab. METHODS: We performed a bicentric, retrospective, case-control study in two French hospitals. Patients with NSCLC treated with chemotherapy after nivolumab between January 2015 and January 2016 were included. Each case was matched on age and number of previous lines to one lung cancer patient who had not received nivolumab. Each CT-scanner has been reviewed and the objective response to chemotherapy was assessed for each patient according to the RECIST 1.1 criteria. RESULTS: Thirty-one patients with advanced NSCL who had at least received one cycle of chemotherapy after progression under nivolumab in the inclusion period were matched to 31 controls. The median age for cases was 59 yo and the predominant tumoral histology was adenocarcinoma (77%). The progression free survival (PFS) was 2.95 months in the studied group vs 2.69 months (P=0.18) in the control group. At best response, disease control (DC=partial response and stable disease) was better in the case group than in the control group (58% vs 39%, P=0.127). Cases were about five times more likely to get objective response to best evaluation than controls (OR=5.043 [95% CI: 0.975-26.086]; P=0.054). The overall survival (OS) was 7.3 months in the case group and 3.3 months in the control group (P=0.074). Patients who have been treated with targeted therapy instead of chemotherapy and patients with squamous lung cancer had worst PFS and OS. CONCLUSION: In advanced NSCLC, the chemotherapy progression free survival does not seem higher when administered after nivolumab. However, when administered post-nivolumab, traditional chemotherapy has 5 times more chances to achieve objective response and seems to improve overall survival of cases. Pooled analysis with other similar studies might be interesting for a next step.
