RESUMEN
BACKGROUND: Immune checkpoint inhibitors (ICIs) have become the standard of care for numerous malignancies. Emerging evidence suggests that the time of day (ToD) of ICI administration could impact the outcomes of patients with cancer. The consistency of ToD effects on ICI efficacy awaits initial evaluation. MATERIALS AND METHODS: This meta-analysis integrates progression-free survival (PFS) and overall survival (OS) data from studies with a defined 'cut-off' ToD. Hazard ratios (HRs) [95% confidence interval (CI)] of an earlier progression or death according to 'early' or 'late' ToD of ICIs were collected from each report and pooled. RESULTS: Thirteen studies involved 1663 patients (Eastern Cooperative Oncology Group performance status 0-1, 83%; males/females, 67%/33%) with non-small-cell lung cancer (47%), renal cell carcinoma (24%), melanoma (20%), urothelial cancer (5%), or esophageal carcinoma (4%). Most patients received anti-programmed cell death protein 1 or anti-programmed death-ligand 1 (98%), and a small proportion also received anti-cytotoxic T-lymphocyte-associated protein 4 (anti-CTLA-4) (18%). ToD cut-offs were 13:00 or 14:00 (i.e. ICI median infusion time), for six studies, and 16:00 or 16:30 (i.e. reported threshold for weaker vaccination responses) for seven studies. Pooled analyses revealed that the early ToD groups had longer OS (HR 0.50, 95% CI 0.42-0.58; P < 0.00001) and PFS (HR 0.51, 95% CI 0.42-0.61; P < 0.00001) compared with the late ToD groups. CONCLUSIONS: Patients with selected metastatic cancers seemed to largely benefit from early ToD ICI infusions, which is consistent with circadian mechanisms in immune-cell functions and trafficking. Prospective randomized trials are needed to establish recommendations for optimal circadian timing of ICI-based cancer therapies.

In systemic sclerosis, the presence of an anti-RNA polymerase III antibody (ARNpol3) is associated with an increased risk of cancer. The characteristic picture of this serotype includes severe diffuse cutaneous involvement, a high risk of renal scleroderma crisis and a 10 year survival of only around 30%. Pulmonary involvement is less common. We report the case of a woman initially treated for drug-induced acute interstitial lung disease revealing chronic interstitial pneumonia with autoimmune features. The disease evolved in three stages with the occurrence of a rapidly progressive diffuse skin sclerosis with anti-ARNPol3 antibodies in the context of ovarian cancer remission.

INTRODUCTION: Immune checkpoint inhibitors (ICIs) have revolutionised cancer care especially in lung cancer. New response patterns have been described under ICIs such as pseudo-progression or hyper-progressive disease (HPD). The definition of HPD is yet to be consensual. The aim of this study was to suggest a clinical definition of nivolumab-refractory patients and find factors associated with this entity. METHODS: We performed a multi centric retrospective study including all patients who received nivolumab for the treatment of advanced non-small cell lung cancer (NSCLC) during the French authorisation for temporary use in 2015. RESULTS: 303 patients were included in the cohort and 292 had details on the number of nivolumab injections received. 57 patients (20%) were nivolumab-refractory. These patients had worse PS at nivolumab initiation (p < 0.0001), shorter duration of treatment before nivolumab (p = 0.028) and had dramatically shorter nivolumab overall survival (p < 0.0001) than patients who did not present with refractory disease. CONCLUSION: Nivolumab-refractory disease can affect up to 20% of patients treated with nivolumab for advanced NSCLC with dramatically shortened survival rates. Further studies are needed to understand the precise mechanisms leading to refractory disease as well as its management.

INTRODUCTION: Innate immunity represents the first step of activation of the immune system and dictates the quality of adaptive immune responses. Studies have reported links between systemic inflammatory or innate immune markers and prognosis in patients with lung cancer. To our knowledge, the prospective and concomitant study of these systemic markers has never been performed. METHODS: Advanced treatment-naive non-small cell lung cancer (NSCLC) patients eligible for first-line platinum-based chemotherapy were prospectively included from December 2012 to July 2015 (N = 148). Blood samples of patients were collected before the first cycle for fresh NK cell phenotyping. Peripheral blood mononuclear cells were cryopreserved for natural cytotoxicity receptor (NCR) genotyping as well as sera for NCR's ligand quantification. Data on leukocytes, neutrophils and monocyte counts and lactate dehydrogenase (LDH) levels were extracted from electronic medical records. RESULTS: Among all studied markers, monocytosis, neutrophilia, leucocytosis, high LDH and sBAG6 levels and reduced levels of NCR3 transcripts were associated with poor overall survival (OS) in univariate analysis. The levels of NCR3 transcripts was linked to age, number of metastatic sites, monocyte counts, LDH and sBAG6 levels. Neutrophilia was associated to high sBAG6 levels. NCR3 was the unique innate immune parameter that remained as an independent factor associated with both OS (P = 0.003) and progression-free survival (P = 0.009) in the multivariate analysis. CONCLUSION: This study brought evidence that these biomarkers are entangled; parameters associated with an inflammatory process were related to reduced levels of NCR3 transcripts. Finally, the level of NCR3 transcripts was independently associated with outcomes in treatment-naive patients with advanced NSCLC.

Anti-PD1 immunotherapies have become an essential treatment for bronchial cancer. According to published studies, PD1 and PD-L1 inhibitors have a better toxicity profile than chemotherapy. Nevertheless, some immune related toxicities can be potentially severe, such as induced interstitial lung disease (ILD). Currently, ILD patients are excluded from clinical trials using immunotherapy in lung cancer. IPF is the most frequent and severe form of ILD. Lung cancer represents a major complication of this disease and to date few data exist on the safety of immunotherapy in this context. We report 3 cases of IPF with lung cancer treated by nivolumab. All had a clinically mild to moderate IPF. The patients had received at least one line of chemotherapy before nivolumab and had progressive, metastatic lung cancer. Two patients experienced rapid cancer progression without immune toxicities. The third had a partial response but developed grade III immune colitis that led to discontinuation of the treatment. None developed lung toxicity or worsening of IPF on CT during follow-up, and death was always related to progression of the cancer. In our series of three patients with IPF, nivolumab was well tolerated with regard to their pulmonary condition. As inflammation and autoimmunity are probably marginal mechanisms in the pathogenesis of IPF, we do not believe that the presence of IPF should definitely disqualify potential candidates for treatment with nivolumab. Decisions should be taken, case-by-case, in selected patients without severe IPF and with no evidence of autoimmunity. In view of the epidemiology of lung cancer in IPF and the critical role of immunotherapy in the management of lung cancer, studies of prospective cohorts are urgently needed in this population.

OBJECTIVES: Thymic epithelial neoplasms (TENs) represent a rare entity with poor prognosis and limited systemic treatment options. The aim of this study was to assess the clinical benefit, the efficacy and toxicities of agents for patients with TEN enrolled in Phase I trials. MATERIALS AND METHODS: We reviewed retrospectively patients with advanced TEN enrolled in Phase I trials at Gustave Roussy (DITEP) between 1994 and 2012. Efficacy was assessed using RECIST version 1.1. RESULTS: Twenty-two treated patients were enrolled (15 with thymic carcinoma, 7 with thymoma). The median number of prior systemic therapies was 2 (0-8). The median age was 50 years (range 23-72), and 4 females were treated. Treatments received encompassed mTOR inhibitor (mTORi) in 4 of patients, antiangiogenic agents (AA) in 11 patients, and other targeted therapies in 7 patients. 18% had grade 3-4 toxicity, 85% all grade toxicity and no toxic death was reported. One patient experienced a complete response (CR) and 3 a partial response (PR); 16 patients had stable disease (median 6.6 months; range 1.0-30.7) and 2 had a progressive disease. The median overall survival was 54.5 months (95% CI 25-75.50). The median progression free survival (PFS) was 6.6 months (95% CI 1.35-11.59). Median PFS was 11.6 months for mTORi, 6.9 for AA, and 6.6 for other targeted therapies. CONCLUSION: Phase I trials appear as a sound therapeutic option in TENs pts progressing after standard treatments. Use of AA and mTORi seem to yield a good clinical response and warrant further investigation.

A 61-year-old man, with a tuberous sclerosis, experienced severe acute reactions during a concomitant chemoradiotherapy regimen after 22Gy and one cycle of 5-fluorouracil-cisplatinum. He was treated for a cervical squamous cell lymph node of unknown origin. Grade 3 mucitis and epitheliitis were observed only in the irradiated fields and required the end of the radiotherapy. Tuberous sclerosis is characterized by a loss of the TSC2 function, with a permanent activation of the mTOR pathway. Logically, some kind of "radioresistance" should be observed. Increased radiosensitivity is paradoxical. This case illustrates how radiosensitivity is a complex phenomenon and clinically unpredictable. Efficiency of the protocols associations of mTOR inhibitors and radiotherapy should be carefully scrutinized.
