Abstract

Simple Summary Many kinase inhibitors have been tested as potential alternatives for the treatment of castration-resistant prostate cancers. However, none of these clinical trials led to drug approval despite interesting responses. Our study reveals that genes involved in drug metabolism and their master regulator PXR (Pregnane X Receptor) could be responsible, at least in part, for these disappointing results as they can modulate tumor cell response to specific kinase inhibitors. We found that stable expression of PXR sensitized prostate cancer cells to erlotinib, dabrafenib, and afatinib, while it rendered cells resistant to dasatinib and had no effect for other inhibitors tested. We also report for the first time that sensitization to afatinib is due to an alteration in drug transport that involves the SLC16A1 monocarboxylate transporter. Together, our results further indicate that PXR might be considered as a biomarker of response to kinase inhibitors in castration-resistant prostate cancers. Abstract Resistance to castration is a crucial issue in the treatment of metastatic prostate cancer. Kinase inhibitors (KIs) have been tested as potential alternatives, but none of them are approved yet. KIs are subject of extensive metabolism at both the hepatic and the tumor level. Here, we studied the role of PXR (Pregnane X Receptor), a master regulator of metabolism, in the resistance to KIs in a prostate cancer setting. We confirmed that PXR is expressed in prostate tumors and is more frequently detected in advanced forms of the disease. We showed that stable expression of PXR in 22Rv1 prostate cancer cells conferred a resistance to dasatinib and a higher sensitivity to erlotinib, dabrafenib, and afatinib. Higher sensitivity to afatinib was due to a ~ 2-fold increase in its intracellular accumulation and involved the SLC16A1 transporter as its pharmacological inhibition by BAY-8002 suppressed sensitization of 22Rv1 cells to afatinib and was accompanied with reduced intracellular concentration of the drug. We found that PXR could bind to the SLC16A1 promoter and induced its transcription in the presence of PXR agonists. Together, our results suggest that PXR could be a biomarker of response to kinase inhibitors in castration-resistant prostate cancers.

Abstract

TO THE EDITOR : Patients with chronic lymphocytic leukemia (CLL) exhibit a variety of skin lesions including mostly non-specific cutaneous manifestations (such as cutaneous infections or exaggerated reactions to insect bite) and secondary cutaneous malignancies, as patients are at high risk of developing basal cell carcinoma, squamous cell carcinoma, melanoma, and Merkel cell carcinoma. Specific cutaneous infiltration by neoplastic B lymphocytes with clinically identifiable skin lesions, also called leukemia cutis (LC), is more uncommon and has seldom been reported in chronic lymphocytic leukemia.

Abstract

Background Currently, oral targeted therapies are known to be effective and are frequently used to treat metastatic cancer patients, but fatigue is a frequently reported early side effect of these treatments. This fatigue may impact the patient’s treatment adherence and result in a negative impact on quality of life. Physical exercise significantly improved the general well-being and quality of life of advanced cancer patients. However, there is no specific physical activity program adapted for patients with advanced disease. Methods QUALIOR is a two-part, randomized, open-label, and multicenter with two arms phase II/III trial. Patients (phase II: n = 120; phase III: n = 312) with metastatic cancer (breast cancer, kidney cancer, lung cancer, and other cancers [including but not limited to colon cancer, melanoma, sarcoma, or hepatocarcinoma]) treated with a first- or second-line oral targeted therapy without chemotherapy will be included. Patients will be randomized (2:1) to a 3-month supervised home-based standardized physical activity program or to a recommended adapted physical activity (via a booklet). The primary objective of the phase II is to evaluate the feasibility of the supervised program. The primary objective of the phase III is the evaluation of the benefit of the supervised home-based program compare to the recommended program in terms of fatigue and quality of life at 3 months. The secondary objectives aim to evaluate the impact of the supervised program on fatigue over time, pain, physical capacities, psychosocial and cognitive functions, general quality of life, frequency of dose reduction and patients’ adherence to the targeted therapy, overall survival, and progression-free survival. This study will also evaluate the medico-economic impact of supervised program compared to the recommended adapted physical activity program. Discussion The aim of this study is to evaluate home-based physical exercise program for metastatic cancer patients treated with oral targeted therapies to help patients to cope with fatigue and improve quality of life. Trial registration This trial was registered in ClinicalTrials.gov since May 2017 (NCT03169075).

Abstract

International audience; Purpose: To assess the association between PD-L1 expression and disease-free survival (DFS) in High-Risk Non-Muscle Invasive Bladder Cancer (HR-NMIBC) patients treated with intravesical Bacillus Calmette-Guerin (BCG) instillations (IBI).Methods: Retrospective study in five French centres between 2001 and 2015. Participants were 140 patients with histologically confirmed HR-NMIBC. All patients received induction and maintenance IBI. Pathological stage/grade, concomitant carcinoma in situ, lesion number and tumour size were recorded. CD3, CD8 and PD-L1 expression in tumour cells and in T cells in the tumour microenvironment (TME) was determined immunohistochemically. Median follow-up was 54.2 months. The primary outcome measure was DFS. Univariable and multivariable analyses were performed using the log rank test and Cox proportional hazards model.Results: Of the 140 NMIBC, 52 (37.1%) were Ta, 88 (62.9%) were T1 and 100% were high grade. Median number of maintenance IBI was six (range 1-30). Twenty-five (17.9%) patients had recurrence/progression. In multivariable analysis, age (HR 1.07 [95% CI 1.02-1.13], p = 0.009), PD-L1 expression in tumour cells (HR per 10 units = 1.96 [95% CI 1.28-3.00], p = 0.02) and CD3/CD8 ratio (HR per 10 units = 3.38 [95% CI 1.61-7.11], p = 0.01) were significantly associated with DFS. However, using the cut-off corresponding for each PD-L1 antibodies, PD-L1 + status was not associated with DFS.Conclusion: Despite an association between PD-L1 expression and BCG failure in HR-NMIBC, the PD-L1 + status was not a prognostic factor in the response of BCG. Moreover, we confirmed the key role played by the IC within the microenvironment in BCG treatment. These findings highlighted the rationale to combine BCG and PD-L1/PD-1 antibodies in early bladder cancer.

Abstract

International audience; Myeloproliferative neoplasms are clonal disorders characterized by the presence of several gene mutations associated with particular hematologic parameters, clinical evolution, and prognosis. Few therapeutic options are available, among which interferon α (IFNα) presents interesting properties like the ability to induce hematologic responses (HRs) and molecular responses (MRs) in patients with JAK2 mutation. We report on the response to IFNα therapy in a cohort of 31 essential thrombocythemia (ET) patients with CALR mutations (mean follow-up of 11.8 years). HR was achieved in all patients. Median CALR mutant allelic burden (%CALR) significantly decreased from 41% at baseline to 26% after treatment, and 2 patients even achieved complete MR. In contrast, %CALR was not significantly modified in ET patients treated with hydroxyurea or aspirin only. Next-generation sequencing identified additional mutations in 6 patients (affecting TET2, ASXL1, IDH2, and TP53 genes). The presence of additional mutations was associated with poorer MR on CALR mutant clones, with only minor or no MRs in this subset of patients. Analysis of the evolution of the different variant allele frequencies showed that the mutated clones had a differential sensitivity to IFNα in a given patient, but no new mutation emerged during treatment. In all, this study shows that IFNα induces high rates of HRs and MRs in CALR-mutated ET, and that the presence of additional nondriver mutations may influence the MR to therapy.

Abstract

International audience; BACKGROUND:Early risk-stratified chemotherapy is a standard treatment for breast, colorectal, and lung cancers, but not for high-risk localised prostate cancer. Combined docetaxel and estramustine improves survival in patients with castration-resistant prostate cancer. We assessed the effects of combined docetaxel and estramustine on relapse in patients with high-risk localised prostate cancer.METHODS:We did this randomised phase 3 trial at 26 hospitals in France. We enrolled patients with treatment-naive prostate cancer and at least one risk factor (ie, stage T3-T4 disease, Gleason score of ≥8, prostate-specific antigen concentration >20 ng/mL, or pathological node-positive). All patients underwent a staging pelvic lymph node dissection. Patients were randomly assigned (1:1) to either androgen deprivation therapy (ADT; goserelin 10·8 mg every 3 months for 3 years) plus four cycles of docetaxel on day 2 at a dose of 70 mg/m(2) and estramustine 10 mg/kg per day on days 1-5, every 3 weeks, or ADT only. The randomisation was done centrally by computer, stratified by risk factor. Local treatment was administered at 3 months. Neither patients nor investigators were masked to treatment allocation. The primary endpoint was relapse-free survival in the intention-to-treat population. Follow-up for other endpoints is ongoing. This study is registered with ClinicalTrials.gov, number NCT00055731.FINDINGS:We randomly assigned 207 patients to the ADT plus docetaxel and estramustine group and 206 to the ADT only group. Median follow-up was 8·8 years (IQR 8·1-9·7). 88 (43%) of 207 patients in the ADT plus docetaxel and estramustine group had an event (relapse or death) versus 111 (54%) of 206 in the ADT only group. 8-year relapse-free survival was 62% (95% CI 55-69) in the ADT plus docetaxel and estramustine group versus 50% (44-57) in the ADT only group (adjusted hazard ratio [HR] 0·71, 95% CI 0·54-0·94, p=0·017). Of patients who were treated with radiotherapy and had data available, 31 (21%) of 151 in the ADT plus docetaxel and estramustine group versus 26 (18%) of 143 in the ADT only group reported a grade 2 or higher long-term side-effect (p=0·61). We recorded no excess second cancers (26 [13%] of 207 vs 22 [11%] of 206; p=0·57), and there were no treatment-related deaths.INTERPRETATION:Docetaxel-based chemotherapy improves relapse-free survival in patients with high-risk localised prostate cancer. Longer follow-up is needed to assess whether this benefit translates into improved metastasis-free survival and overall survival.FUNDING:Ligue Contre le Cancer, Sanofi-Aventis, AstraZeneca, Institut National du Cancer.

Abstract

International audience; See an invited perspective on this article on page 1043.This multicenter phase II study investigated a selective radiotherapy dose increase to tumor areas with significant (18)F-misonidazole ((18)F-FMISO) uptake in patients with non-small cell lung carcinoma (NSCLC). Methods: Eligible patients had locally advanced NSCLC and no contraindication to concomitant chemoradiotherapy. The (18)F-FMISO uptake on PET/CT was assessed by trained experts. If there was no uptake, 66 Gy were delivered. In (18)F-FMISO-positive patients, the contours of the hypoxic area were transferred to the radiation oncologist. It was necessary for the radiotherapy dose to be as high as possible while fulfilling dose-limiting constraints for the spinal cord and lungs. The primary endpoint was tumor response (complete response plus partial response) at 3 mo. The secondary endpoints were toxicity, disease-free survival (DFS), and overall survival at 1 y. The target sample size was set to demonstrate a response rate of 40% or more (bilateral α = 0.05, power 1-β = 0.95). Results: Seventy-nine patients were preincluded, 54 were included, and 34 were (18)F-FMISO-positive, 24 of whom received escalated doses of up to 86 Gy. The response rate at 3 mo was 31 of 54 (57%; 95% confidence interval [CI], 43%-71%) using RECIST 1.1 (17/34 responders in the (18)F-FMISO-positive group). DFS and overall survival at 1 y were 0.86 (95% CI, 0.77-0.96) and 0.63 (95% CI, 0.49-0.74), respectively. DFS was longer in the (18)F-FMISO-negative patients (P = 0.004). The radiotherapy dose was not associated with DFS when adjusting for the (18)F-FMISO status. One toxic death (66 Gy) and 1 case of grade 4 pneumonitis (>66 Gy) were reported. Conclusion: Our approach results in a response rate of 40% or more, with acceptable toxicity. (18)F-FMISO uptake in NSCLC patients is strongly associated with poor prognosis features that could not be reversed by radiotherapy doses up to 86 Gy.

Abstract

International audience; The possibility to monitor pulsed dose-rate facilities by means of real-time fibered dosimetry is investigated. A system based on the luminescence of the SrS:Ce,Sm is used to monitor pulses from a medical accelerator with four different dose-rates. The RL signal is characterized using a dedicated acquisition system. The RL recorded is linear with dose-rate and dose. The stem effect due to both Cerenkov emission and photoluminescence in the fiber was also investigated with 18 MV photons and 12 MeV electrons.
