Outcomes Analysis of Patients Receiving Local Ablative Therapy for Oligoprogressive Metastatic NSCLC Under First-Line Immunotherapy.

CONTEXT: Nonsmall Cell Lung Cancer (NSCLC) treatment relies on first-line immunotherapy as single agent or combined with chemotherapy. Oligoprogression may be observed in this setting. MATERIAL AND METHOD: We performed a European multicentric retrospective study on patients treated with first-line immunotherapy, who presented with oligoprogressive disease, treated with a local ablative treatment. RESULTS: A total of 61 patients were retrospectively included between 2018 and 2022. Twenty-four patients (39%) received immunotherapy as single agent, and 37 (61%) chemo-immunotherapy. First oligoprogression occurred more frequently in pre-existing metastatic sites (47% of patients). Median PFS1 (defined as time to first oligoprogression) was 11.5 months [IC95%: 10.0-12.3]. We observed that 37 patients (61%) progressed after first oligoprogression, and 20 (54%) from them presented second oligoprogression. Median OS for the whole cohort was 72.0 months [IC95%: 19.3-124.8], with positive correlation between OS and PFS1 (R=0.65, P < .0001). After loco-ablative treatment with radiotherapy, disease control rate was 89% with ablative radiotherapy: 88% with conventional radiotherapy, and 89% with stereotactic radiotherapy. CONCLUSION: Patients with oligoprogression under/after immunotherapy have better prognosis with a high risk of subsequent oligoprogression.

Changed relationships between patient and health care provider have given patients a greater role in their care. Nowadays, they have the opportunity to be involved in decision-making regarding any diagnostic, therapeutic or monitoring intervention related to their disease. Access to international scientific data through the web, the activity of different patient associations, and the information given by their referring physician can enrich their knowledge about their disease and its possible treatments. In addition to the objective criteria usually assessed, the role currently assumed by patient associations in clinical research helps to identify their expectations. In addition, a number of new tools allow the thoracic oncologist to better understand patients' wishes. Health authorities' use of patient-reported outcomes and patients' use of digital applications contribute to improved survival without any deleterious impact on quality of life. Web applications designed to monitor a patient's toxicities during treatment are now commercially available. To meet our patients' expectations, we are called upon to incorporate these different digital tools into our daily practice.

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.

Real-world outcomes according to treatment strategies in ALK-rearranged non-small-cell lung cancer (NSCLC) patients: an Italian retrospective study.

PURPOSE: Anaplastic lymphoma kinase (ALK) rearrangement confers sensitivity to ALK inhibitors (ALKis) in non-small-cell lung cancer (NSCLC). Although several drugs provided an impressive outcome benefit, the most effective sequential strategy is still unknown. We describe outcomes of real-life patients according to the treatment strategy received. PATIENTS: We retrospectively collected 290 ALK rearranged advanced NSCLC diagnosed between 2011 and 2017 in 23 Italian institutions. RESULTS: After a median follow-up of 26 months, PFS for crizotinib and a new generation ALKis were 9.4 [CI 95% 7.9-11.2] and 11.1 months [CI 95% 9.2-13.8], respectively, while TTF were 10.2 [CI 95% 8.5-12.6] and 11.9 months [CI 95% 9.7-17.4], respectively, being consistent across the different settings. The composed outcomes (the sum of PFS or TTF) in patients treated with crizotinib followed by a new generation ALKis were 27.8 months [CI 95% 24.3-33.7] in PFS and 30.4 months [CI 95% 24.7-34.9] in TTF. The median OS from the diagnosis of advanced disease was 39 months [CI 95% 31.8-54.5]. Patients receiving crizotinib followed by a new generation ALKis showed a higher median OS [57 months (CI 95% 42.0-73.8)] compared to those that did not receive crizotinib [38 months (CI 95% 18.6-NR)] and those who performed only crizotinib as target agent [15 months (CI 95% 11.3-34.0)] (P < 0.0001). CONCLUSION: The sequential administration of crizotinib and a new generation ALKis provided a remarkable clinical benefit in this real-life population, being an interesting option to consider in selected patients.

Current opinions in immune checkpoint inhibitors rechallenge in solid cancers.

Immune checkpoint inhibitors (ICI) completely upset the therapeutic algorithm of several type of solid cancer conferring in some patients a long clinical benefit with an acceptable toxicity. ICI rechallenge is an attractive option being a palliative chemotherapy the only alternative treatment in most of cases. Despite this strategy recently entered into the clinical practice, no widely recognized recommendation is currently available to select the good candidates. Anti-Cytotoxic T Lymphocyte Antigen 4 (Anti-CTLA4) rechallenge and a sequential administration of anti-CTLA4 and anti-Programmed cell Death protein 1 (anti-PD1) or Anti-Programmed Death Ligand 1 (anti-PDL1) agents have been explored in melanoma patients in several clinical trials while the anti-PD1/anti-PDL1 rechallenge has been little investigated. Here we performed a literature revision about efficacy and tolerability of ICI rechallenge across solid tumors also focusing on inclusion criteria used into clinical trials.
