RESUMO

Over the past 20 years, several innovative therapies have been implemented in the treatment of lung cancer that have had reported survival benefits in clinical trials. Whether these improvements translate into the clinic setting has not been studied yet. We retrospectively analyzed all patients consecutively treated at Institute Curie for metastatic lung cancer. Diagnosis date was used to define three periods, based on the approvals of novel treatment strategies in the first-line setting, including targeted therapies in 2010 and immunotherapy in 2018. Endpoints included Overall survival (OS), survival rate of 2 years and 5 years, and a conditional survival rate of 2 years (if still alive at 6 months from treatment initiation). A total of 673 patients were identified for Period 1-2000 to 2009, 752 for Period 2-2010 to 2017, and 768 for Period 3-2018 to 2020. Median OS in the whole cohort was 11.1, 15.5, and 16.2 months, respectively. Median OS for patients with NSCLC or SCLC was 11.2, 17.2, and 18.2 months, or 10.9, 11.7, and 11.2 months, respectively. The two-year conditional survival was more favorable for NSCLC than SCLC patients. Outcomes were statistically higher for women as compared to men in all periods and all subgroups. Survival of patients with metastatic lung cancer has improved over the past 20 years, mostly in NSCLC, along with the implementation of novel treatment strategies.

RESUMO

BACKGROUND: Post-operative whole breast radiotherapy for breast cancer (BC) may increase the risk of subsequent lung cancer (LC). The impact of radiotherapy intensification (boost) has not been specifically explored in this context. We investigated the role of radiation modalities on the development of subsequent LC among our patients treated by radiotherapy for localized BC. METHODS: All patients with a diagnosis of LC between 2000 and 2020 with a history of prior localized BC treated by surgery and post-operative radiotherapy were retrospectively reviewed. Primary endpoint was time to first diagnosis of LC after BC treatment with radiotherapy (RT). RESULTS: From 98 patients who developed subsequent LC after primary BC treated with post-operative RT, 38% of patients (n = 37) received an additional RT boost, and 46% (n = 45) received hormonal treatment post radiation. A total of 61% (n = 60) were smokers. With regards to LC characteristics, adenocarcinoma was the most frequent histology (68%, n = 66); 36% (n = 35) harbored at least 1 molecular alteration, 57% (n = 20) of them being amenable to targeted therapy. Median time to first diagnosis of LC was 6 years [1.7-28.4 yrs] in the whole cohort. In the subgroup of patients treated with boost this time was reduced to 4 years [1.8-20.8 years] compared to 8 years for patients without boost [1.7-28.4 yrs] (p = 0.007). Boost, smoking usage, endocrine therapy, and age <50 yrs old at BC radiation remained independent factors associated with shorter time to first diagnosis of LC after BC treatment. DISCUSSION: We report for the first time the potential impact of boost -part of BC radiation treatment- for BC on the risk of subsequent LC. The impact of low dose radiation on lung parenchyma could explain this phenomenon, but the underlying physiopathology is still under investigation. This work highlights the need for clinicians to identify patients at risk of developing faster subsequent thoracic malignancy after BC radiation, for implementing personalized surveillance.

RESUMO

BACKGROUND: The IONESCO (IFCT-1601) trial assessed the feasibility of neoadjuvant durvalumab, for early-stage resectable non-small-cell lung cancer (NSCLC). METHODS: In a multicenter, single-arm, phase II trial, patients with IB (≥4 cm)-IIIA, non-N2, resectable NSCLC received three doses of durvalumab (750 mg every 2 weeks) and underwent surgery between 2 and 14 days after the last infusion. The primary endpoint was the complete surgical resection rate. Secondary endpoints included tumor response rate, major histopathological response (MPR: ≤10% remaining viable tumor cells), disease-free survival (DFS), overall survival (OS), durvalumab-related safety, and 90-day postoperative mortality (NCT03030131). RESULTS: Forty-six patients were eligible (median age 60.9 years); 67% were male, 98% were smokers, and 41% had squamous cell carcinoma. Regarding tumor response, 9% had a partial response, 78% had stable disease, and 13% had progressive disease. Among the operated patients (n=43), 41 achieved complete resection (89%, 95% CI 80.1% to 98.1%)), and eight achieved MPR (19%). The 12-month median OS and DFS rates were 89% (95% CI 75.8% to 95.3%) and 78% (95% CI 63.4% to 87.7%), respectively (n=46). The median follow-up was 28.4 months (12.8-41.1). All patients in whom MPR was achieved were disease-free at 12 months compared to only 11% of those with >10% residual tumor cells (p=0.04). No durvalumab-related serious or grade 3-5 events were reported. The unexpected 90-day postoperative mortality of four patients led to premature study termination. None of these four deaths was considered secondary to direct durvalumab-related toxicity. CONCLUSIONS: Neoadjuvant durvalumab given as monotherapy was associated with an 89% complete resection rate and an MPR of 19%. Despite an unexpectedly high rate of postoperative deaths, which prevented us from completing the trial, we were able to show a significant association between MPR and DFS.

RESUMO

BACKGROUND: To analyze the outcomes of patients with brain metastases (BM) from non-small cell lung cancer (NSCLC) treated with immunotherapy (IT) and stereotactic radiotherapy (SRT) and to study the impact of the sequence between the two modalities. METHODS: The authors reviewed the records of 51 patients with 84 BM from NSCLC treated at Institut Curie with IT and SRT. BM were categorized into three groups: 'SRT before IT', 'concurrent SRT and IT', and 'SRT after IT.' Regional progression-free interval (R-PFI) and overall survival (OS) were estimated using the Kaplan-Meier method. RESULTS: After a median follow-up from SRT of 22.5 months (2.7-47.3), the 1-year and 2-year OS were 69.7% (95%CI [58.0-83.8]) and 44.0% [30.6-63.2], respectively. Concerning distant intracranial control, the 1-year and 2-year R-PFI were 40.1% [30.1-53.3] and 35.2% [25.1-49.4], respectively. Moreover, one-year R-PFI in 'SRT before IT', 'concurrent SRT and IT', and 'SRT after IT' groups were 24.1%, 49.6%, and 34.2%, respectively (p = 0.094). The type of therapeutic sequence did not appear to impact the risk of brain necrosis. CONCLUSIONS: The concurrent administration of SRT and IT appeared to offer the best locoregional control, without increasing the risk of toxicity, compared to patients treated with SRT before or after IT.

RESUMO

Introduction: Compared with docetaxel, the phase-III trial, ULTIMATE, showed a significant improvement of progression-free survival (PFS) with paclitaxel-bevacizumab combination (PB) as second- or third-line treatment in advanced non-small cell lung cancer (NSCLC). With the increase of immunotherapy treatment in first-line settings, the optimal treatment after first-line failure must be redefined. Methods: This multicentric retrospective study identified all advanced NSCLC patients treated with PB as second-line therapy and beyond. The main efficacy outcomes assessed were objective response rate (ORR), disease control rate (DCR), PFS, and overall survival (OS). The adverse events were reported according to Common Terminology Criteria for Adverse Events (CTCAE). Results: From January 2010 to February 2020, 314 patients in 16 centers received the PB combination. Most patients were male (55%), with a median age of 60 years (19-82), 95% had adenocarcinoma, 27% had a performance status ⩾2, 45% had brain metastases at the time of inclusion. They mostly received the PB combination either in second (20%) or in third-line (39%), and 28% were treated just after ICI failure. ORR and DCR were 40% and 77%, respectively; median PFS and OS were 5.7 [interquartile range (IQR): 3.2-9.6] and 10.8 [IQR: 5.3-19.6] months, respectively. All grade adverse events concerned 82% of patients, including 53% asthenia and 39% neurotoxicity, and 25% of patients continued monotherapy (mostly with bevacizumab) alone due to toxicity. Median PFS for patients treated after ICI failure (ICI+) was significantly superior compared with those not previously treated with ICI (ICI-): 7.0 [IQR: 4.2-11.0] versus 5.2 [IQR: 2.9-8.8] months, p = 0.01, without statistically significant difference for OS between these two groups. In multivariate analysis, factors associated with superior PFS were previous ICI treatment and performance status of 0-1. Only a performance status of 0-1 was associated with superior OS. Conclusion: PB combination as second-line treatment or beyond for advanced non-squamous NSCLC had acceptable toxicity and a clinically relevant efficacy and is an option as salvage treatment for these patients, more particularly after ICI progression.

RESUMO

BACKGROUND: The optimal treatment duration of ICIs for patients with advanced NSCLC remains uncertain. In phase 3 clinical trials, treatment continued for 2 years or until disease progression with similar long-term survival rates. Real-life data are missing. PATIENTS AND METHODS: This academic multicentric retrospective study aims at analyzing the characteristics of patients who discontinued treatment after at least 18 months of ICI monotherapy, in the setting of controlled disease. RESULTS: Of the 1127 patients treated with immunotherapy in the given period in six centers, 107 patients had their tumor controlled after at least 18 months of treatment and 54 (50%) of them had discontinued ICI. The median duration of treatment was 26 months. Treatment was stopped due to prescriber choice or toxicity in 46% and 22% of cases, respectively. After a median follow-up of 21 months from ICI discontinuation (95% CI 15.0-26.1 months), 18 (33%) patients experienced tumor progression after a median time of 10.0 months (range 2-33). From discontinuation, 12-month overall survival (OS) and progression-free survival (PFS) were 90% (95% CI 77.7-95.7) and 71% (95% CI 56.8-81.5), respectively; 24-month OS and PFS were 84% (95% CI 68.7-92.2) and 63% (95% CI 46.1-76.2), respectively. Duration of disease control after ICI discontinuation was correlated with tumor response at treatment discontinuation: PFS rate at 12 months was 76% after complete response (CR n = 11) or partial response (PR n = 37) and 22% after only stable disease (SD n = 6) as best response, p-value = 0.0002. PFS rate at 12 months was 80% for CR and/or complete metabolic response with 18F-FDG PET/CT (CMR) and 65% for others. Fourteen patients out of the 18 relapse patients received a subsequent treatment: seven with ICI rechallenge (best response 14% PR and 86% SD) and five with localized therapy with 60% CR. CONCLUSIONS: This real-life study provides new insight into long-term outcomes of patients with advanced NSCLC treated with ICI for at least 18 months before treatment discontinuation in the absence of PD. Tumor response and CMR with FDG PET just before therapy discontinuation may be a predictive factor of prolonged disease control upon discontinuation. These results call for caution in discontinuing treatment in patients with stable disease as the best response.

RESUMO

EGFR exon 20 insertions are rare genetic alterations in non-small-cell lung cancers (NSCLCs) that are usually unresponsive to approved EGFR tyrosine kinase inhibitors (TKIs). In this paper, we describe the clinical characteristics, efficacy of EFGR TKIs and chemotherapy, and resulting survival in this population. We retrospectively collected patients with EGFR exon 20 insertions (Exon20ins) from 11 French genetic platforms and paired them (1:2 ratio) with classic Exon 19/21 EGFR mutation patients (controls). Between 2012 and 2017, 35 Exon20ins patients were included. These patients were younger at diagnosis than the controls. All Exon20ins patients who were treated with first-line EGFR TKIs (n = 6) showed progressive disease as the best tumor response. There was no significant difference in the tumor response or the disease control rate with first-line platinum-based chemotherapy between the two groups. A trend towards shorter overall survival was observed in Exon20ins vs. controls (17 months (14-not reach(NR) 95% confidence interval(CI) vs. 29 months (17-NR 95%CI), p = 0.09), respectively. A significant heterogeneity in amino acid insertion in EGFR exon 20 was observed. EGFR exon 20 insertions are heterogeneous molecular alterations in NSCLC that are resistant to classic EGFR TKIs, which contraindicates their use as a first-line treatment.

RESUMO

OBJECTIVES: We aimed to compare the prognostic value of inflammatory biomarkers extracted from pretreatment peripheral blood and [18F]-FDG PET for estimating outcomes in non-small cell lung cancer (NSCLC) patients treated with first-line immunotherapy (IT) or chemotherapy (CT). MATERIALS AND METHODS: In this retrospective multicenter study, we evaluated 111 patients with advanced NSCLC who underwent baseline [18F]-FDG PET/CT before IT or CT between 2016 and 2019. Several blood inflammatory indices were evaluated: derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP) and systemic immune-inflammation index (SII). FDG-PET inflammatory parameters were extracted from lymphoid tissues (BLR and SLR: bone marrow or spleen-to-Liver SUVmax ratios). Association with survival and relationships between parameters were evaluated using Cox prediction models and Spearman's correlation respectively. RESULTS: Overall, 90 patients were included (IT:CT) (51:39pts). Median PFS was 8.6:6.6 months and median OS was not reached:21.2 months. In the IT cohort, high dNLR (>3), high SII (≥1,270) and high SLR (0.77) were independent statistically significant prognostic factors for one-year progression-free survival (1y-PFS) and two-year overall survival (2y-OS) on multivariable analysis. In the CT cohort, high BLR (≥0.80) and high dNLR (>3) were associated with shorter 1y-PFS (HR 2.2, 95% CI 1.0-4.9) and 2y-OS (HR 3.4, 95CI 1.1-10.3) respectively, on multivariable analysis. Finally, BLR significantly but moderately correlated with most blood-based inflammatory indices (CRP, PLR and SII) while SLR was only associated with CRP (p < 0.01 for all). CONCLUSION: In advanced NSCLC patients undergoing first-line IT or CT, pretreatment blood and inflammatory factors evaluating the spleen or bone marrow on [18F]-FDG PET/CT provided prognostic information for 1y-PFS and 2y-OS. These biomarkers should be further evaluated for potential clinical application.

RESUMO

OBJECTIVES: In managing patients with cancer in the COVID-19 era, clinical oncologists and palliative care practitioners had to face new, disrupting and complex medical situations, challenging the quality of the shared decision-making process. During the first lockdown in France, we developed an onco-palliative ethics meeting to enhance the quality of the decision-making process for patients with advanced cancer treated for COVID-19. METHODS: A least one of the institutional ethics committee members was present along with oncologists, palliative care teams, psycho-oncologists, radiologists and intensive care specialists. Specific medical parameters were systematically collected to form a standardised framework for the discussions. RESULTS: The main raised issues were the definition of new criteria for the implementation of invasive resuscitation techniques, optimal ways to adapt or delay anticancer treatment and best procedures to address terminal respiratory failure and end-of-life care. The main clinical and ethical guidelines that emerged during these debates are presented. The palliative care team played a major role in assessing and reporting patients' awareness of cancer-related prognosis and their wishes concerning invasive therapies or transfer to intensive care units, enabling an individualised benefit-risk balance assessment. The ethics committee members ensured continuous monitoring during the discussions. Their function was to recall the main ethical principles including dignity, which is conferred on people when there are treated as having equal status. CONCLUSIONS: The onco-palliative ethics meeting provided a powerful avenue for improvement of collegiality and reinforcement of teamwork, which could be a major protection against burnout for healthcare professionals facing an epidemic onslaught.

RESUMO

BACKGROUND: Concerns have emerged about the higher risk of fatal coronavirus disease 2019 (COVID-19) in cancer patients. In this article, we review the experience of a comprehensive cancer center. METHODS: A prospective registry was set up at Institut Curie at the beginning of the COVID-19 pandemic. All cancer patients with suspected or proven COVID-19 were entered and actively followed for 28 days. RESULTS: Among 9842 patients treated at Institut Curie between March 13 and May 1, 2020, 141 (1.4%) were diagnosed with COVID-19, based on reverse transcription polymerase chain reaction testing and/or computerized tomography scan. In line with our case mix, breast cancer (40.4%) was the most common tumor type, followed by hematological and lung malignancies. Patients with active cancer therapy or/and advanced cancer accounted for 87.9% and 68.9% of patients, respectively. At diagnosis, 78.7% of patients had COVID-19-related symptoms, with an extent of lung parenchyma involvement inferior to 50% in 95.8% of patients. Blood count variations and C-reactive protein elevation were the most common laboratory abnormalities. Antibiotics and antiviral agents were administered in 48.2% and 6.4% of patients, respectively. At the time of analysis, 26 patients (18.4%) have died from COVID-19, and 100 (70.9%) were cured. Independent prognostic factors at the time of COVID-19 diagnosis associated with death or intensive care unit admission were extent of COVID-19 pneumonia and decreased O2 saturation. CONCLUSIONS: COVID-19 incidence and presentation in cancer patients appear to be very similar to those in the general population. The outcome of COVID-19 is primarily driven by the initial severity of infection rather than patient or cancer characteristics.

RESUMO

OBJECTIVE: To determine FDG-PET biomarkers associated with long-term benefit (LTB) and survival in advanced non-small cell lung cancer (NSCLC) patients receiving first-line immunotherapy. METHODS: In this multicenter study, we retrospectively analyzed advanced NSCLC patients with a PD-L1 tumor proportion score (TPS) ≥ 50%, who underwent FDG-PET/CT before first-line pembrolizumab, received from August 2017 to September 2019. Parameters extracted were SUVmax, SUVmean, TMTV (total metabolic tumor volume) and TLG (total lesion glycolysis). LTB was defined as objective (complete or partial) response or stable disease as best overall response, maintained for ≥ 12 months. A multivariate prediction model was developed using logistic regression for LTB and Cox models for progression-free survival (PFS) and overall survival (OS). RESULTS: On the 63 eligible patients, with a median follow-up of 13.4 (range, 1.5-29.1) months, 17 (27%) had LTB. Median PFS and OS were 7.7 months (95%CI 5.0-10.5) and 12.1 months (95%CI 8.6-15.6). In multivariate analyses, high TMTV (> 84cm3) and high tumor SUVmean (> 10.1) remained independent factors for predicting LTB (OR 0.2; p = 0.03 and OR 3.7; p = 0.04) and PFS (HR 2.2; p = 0.02 and HR 0.5; p = 0.045). High TMTV was significantly associated with poor OS (HR 3.1; p = 0.03). No association was observed between tumor SUVmax or TLG and clinical outcomes. CONCLUSIONS: In patients with advanced NSCLC and PD-L1 TPS ≥ 50%, baseline low TMTV and high tumor SUVmean correlate with survival and LTB from upfront pembrolizumab. Beyond the initial staging, FDG-PET/CT scan could provide relevant biomarkers associated with clinical outcomes that should be taken into account when considering first-line treatment options.

RESUMO

INTRODUCTION: About 2-3% of non-small-cell lung cancers (NSCLCs) harbor MET exon-14-skipping (METex14) mutations. Efficacy of the MET-inhibitor crizotinib has been reported, but progression-free survival (PFS) was very short. Immune-checkpoint inhibitors (ICIs) have become a cornerstone of NSCLC treatment but appear to be less effective in non-smokers and against tumors exhibiting oncogenic addiction. We describe 6 remarkable (PFS exceeding 18 months) and durable responses to ICIs of NSCLCs harboring a METex14 mutation. METHODS: Each patient's clinical and biological characteristics, and tumor responses after ICIs were examined. Complete tumor-DNA sequencing was available after starting second-line ICIs, which followed first-line chemotherapy. Tumor-cell programmed cell-death protein-1 ligand-1 (PD-L1) expression on tumor cells was evaluated using antibody clone E1L3N (Cell Signaling Technology). RESULTS: Among 25 patients with METex14-mutated NSCLCs, 13 of whom were ICI-treated, 6 had prolonged responses: 5 women, 1 man; 57-80 years old; 3 never-smokers, 1 ex-smoker and 2 smokers; 5 adenocarcinomas, 1 sarcomatoid carcinoma; 5 received nivolumab, 1 pembrolizumab. No EGFR, BRAF or KRAS mutations (only 1 minority KRAS mutation), or ALK or ROS translocations were detected. No concurrent MET amplification was observed. Tumor-mutation burden was low (<10 mutations/Mb) in 3 tested tumors. Four partial and 2 complete responses were obtained during the first 3 months for 5 patients, while pseudoprogression was initially observed in 1. Tolerance was excellent, with only 1 grade-3 immune-related adverse event. Response was maintained for 18-49 months. CONCLUSION: ICIs could be considered to treat patients whose NSCLCs harbor a METex14 mutation. More biological marker data are needed to identify which patients are most likely to benefit from ICIs.

RESUMO

Background: We aimed to assess the clinical utility of a previously published score combining the total metabolic tumor volume (TMTV) on baseline FDG-PET/CT and pretreatment derived from the neutrophils to lymphocytes ratio (dNLR) for prognostication in NSCLC patients undergoing first-line immunotherapy (IT). Methods: In this multicenter retrospective study, 63 advanced NSCLC patients with a PD-L1 tumor proportion score (TPS) ≥50%, who underwent FDG-PET/CT before first-line IT, treated from January 2017 to September 2019, were enrolled. Associations between this score and the progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and overall response rate (ORR) were evaluated. Results: The median (m) PFS and mOS were 7.7 (95% CI 4.9-10.6) and 12.1 (8.6-15.6) months, respectively, and DCR and ORR were 65% and 58%, respectively. mOS was 17.9 months (14.6 not reached) for the good group versus 13.8 (95%CI 8.4-18.9) and 6.6 (CI 2.0-11.2) months for the intermediate and poor groups, respectively. mPFS was 15.1 (95%CI 12.1-20.0) months for the good group versus 5.2 (1.9-8.5) and 1.9 (95%CI 1.3-2.5) months for the intermediate and poor groups, respectively. The poor prognosis group was associated with DCR and ORR (p < 0.05). Conclusions: The metabolic score combining TMTV on the baseline FDG-PET/CT scan and pretreatment dNLR was associated with the survival and response in a cohort of advanced NSCLC patients with ≥50% PD-L1 receiving frontline IT.

RESUMO

BACKGROUND: Neurologic complications as myelitis are very rare but extremely deleterious adverse effects of both immunotherapy and radiotherapy. Many recent studies have focused on the possible synergy of these two treatment modalities due to their potential to enhance each other's immunomodulatory actions, with promising results and a safe tolerance profile. CASE PRESENTATION: We report here the case of a 68-year-old man with metastatic non-small-cell lung cancer (NSCLC) who developed myelitis after T12-L2 vertebral radiotherapy, with motor deficit and sphincter dysfunction, while on treatment with pembrolizumab (an immune checkpoint inhibitor). The spinal abnormalities detected by magnetic resonance imaging (MRI), suggestive of myelitis, faithfully matched the area previously irradiated with 30 Gy in 10 fractions, six and a half months earlier. After immunotherapy discontinuation and steroid treatment, the patient rapidly and completely recovered. On progression, pembrolizumab was rechallenged and, after 8 cycles, the patient is on response and there are no signs of myelitis relapse. CONCLUSION: The confinement within the radiation field and the latency of appearance are suggestive of delayed radiation myelopathy. Nevertheless, the relatively low dose of radiation received and the full recovery after pembrolizumab discontinuation and steroid therapy plead for the contribution of both radiotherapy and immunotherapy in the causality of this complication, as an enhanced inflammatory reaction on a focal post-radiation chronic inflammatory state. In the three previously described cases of myelopathy occurring after radiotherapy and immunotherapy, a complete recovery had not been obtained and the immunotherapy was not rechallenged. The occurrence of a radiation recall phenomenon, in this case, can not be excluded, and radiation recall myelitis has already been described with chemotherapy and targeted therapy. Safe rechallenges with the incriminated drug, even immunotherapy, have been reported after radiation recall, but we describe it for the first time after myelitis.

RESUMO

Early palliative care is now recommended in international guidelines. A meta-analyze combining seven randomized studies has been published in 2007. It confirms that early palliative care improves patient's quality of life and reduces symptom burden. There is also a trend for the reduction of depressive disorder and the increase of overall survival. Other studies show that early palliative care improves quality of life of patient's relatives and reduces end of life care aggressiveness. Most of the time, early palliative care is introduced as soon as the diagnosis of advanced cancer is made, and the precise referral criteria need to be addressed. Other studies have assessed the palliative care consultation; patient-centered care, focusing on symptom management, filling information and education needs about illness and prognosis, helping psychologic adaptation and coping.

RESUMO

INTRODUCTION: The prognosis of advanced non-small-cell lung cancer (NSCLC) has been improved by development of immune checkpoint inhibitors (ICIs) such as nivolumab for second-line treatment. As phase III trials include only selected patients, we here investigated the clinical factors associated with efficacy and safety of nivolumab in 'real life' patients with advanced NSCLC. METHODS: Clinical and histological characteristics, therapies and survival data of all consecutive patients with advanced NSCLC included prospectively and treated by nivolumab in two French academic hospitals between February 2015 and December 2016 were examined. RESULTS: Sixty-seven patients were included, mostly male (69%), current or former smokers (87%) with PS <2 (73%). Median age was 68.5 years and 42% were aged ≥70 years. According to uni- and multi-variate analyses, only PS 2 (OR = 0.17, 95% CI 0.03-0.99, p = 0.049) and number of previous treatment lines (OR = 0.33, 95% CI 0.13-0.85, p = 0.022) were significantly negatively associated with tumor control. Worse progression-free survival (PFS) was significantly associated with PS 2 (HR = 5.17, 95% CI 1.99-13.43, p = 0.001) and use of steroids (HR = 3.27, 95% CI 1.39-7.69, p = 0.006). Worse overall survival was associated with symptomatic brain metastasis (HR = 3.15, 95% CI 1.23-8.85, p = 0.029). Treatment-related adverse events occurred in 47 patients (70%), symptomatic brain metastasis being significantly associated with Grade ≥3 toxicity (OR = 8.13, 95% CI 1.21-55.56, p = 0.031). Age and nutritional status were not associated with response, PFS, OS or toxicity. CONCLUSION: Our results suggest that nivolumab is not beneficial or safe for patients with PS 2 and symptomatic brain metastases.

RESUMO

INTRODUCTION: Solid organ transplant patients are at heightened risk of several cancers compared to the general population. Secondary to a higher number of procedures and better survival after transplantation, cancer is a rising health concern in this situation. Limited data exist for lung cancer (LC) after renal transplantation. We report here the most important series of renal transplant recipients with lung cancer. METHODS: Retrospective study of all cases of LC diagnosed in three French Renal Transplant Units from 2003 to 2012. A control group consisted of non-transplant patients with LC matched with the cases for age (<30; 30-50; 50-65; >65 years), gender and diagnosis date. We recruited two controls for each case. RESULTS: Thirty patients (median age 60 years; range 29-85; male/female ratio 80/20%) with LC were analysed. LC incidence was 1.89/1000 person-years over the period 2008-2012. All patients were former or active smokers (median 30 pack-years). Transplanted patients had significantly more comorbidities, mainly cardiovascular disease. The median interval of time from kidney transplantation (KT) to diagnosis of LC was 7 years (range 0.5-47 years). LC was incidentally diagnosed in 40%. Most patients (70%) had advanced LC (stage III or IV) disease. Stage of LC at diagnosis was similar in cases and controls. Surgery and chemotherapy were proposed to the same proportion of patients. In cases, mortality was cancer related in 87% and median survival time after diagnosis was 24 months. Survival was not significantly different between the 2 groups. CONCLUSION: Despite frequent medical and radiological examinations, diagnosis of LC is usually made at an advanced stage and the overall prognosis remains poor.

RESUMO

OBJECTIVES: KRAS mutations occur in 20 to 25% of non-small-cell lung cancers (NSCLC) and seem to predict a poor prognosis. There is heterogeneousness in the frequency and spectrum of KRAS mutations, which can be categorized in transitions and transversions. We wondered if subtypes of KRAS mutation were associated with specific clinical phenotypes and specific survival. MATERIALS AND METHODS: Between July 2007 and May 2012, patients with advanced NSCLC and KRAS mutation diagnosed in two university hospitals were included. Clinical and histological characteristics, therapeutics and survival data were collected. RESULTS: Among 635 patients screened for KRAS mutations, 90 were found to be mutated and were included. Median age was 59 years (range: 54-69). Most were males (60%), current or former smokers (63% and 33%, respectively) and had an adenocarcinoma (ADC) (80%). Eighty patients were stage IV and 10 were stage IIIB. Eighty percent of the KRAS mutations were transversions and 20% were transitions. In uni- and multivariate analyses, there was a trend for fewer smokers among patients with transitions than among those with transversions (Odds Ratio [OR]=0.28, 95% CI [0.079-0.999], p=0.05). No significant difference was noted between transitions and transversions for other clinical characteristics. Patients with transitions had more frequently squamous-cell carcinoma (SCC) compared to those with transversions, who had more frequently adenocarcinomas (OR=16.7, 95% CI [2.76-100.8], p=0.002). Seventy-nine patients (86%) had received first-line chemotherapy. No significant difference was seen for disease-control rate, median progression-free survival or overall survival between transitions and transversions. CONCLUSION: A higher proportion of non-smokers and SCC subtypes were observed in the transitions compared to transversions. This confirms the heterogeneity of KRAS mutations and could suggest to expand KRAS testing in SCC to assess impact of RAS in SCC, which remains poorly investigated.

RESUMO

BACKGROUND: Molecularly targeted agents have been reported to have anti-tumour activity for patients whose tumours harbour the matching molecular alteration. These results have led to increased off-label use of molecularly targeted agents on the basis of identified molecular alterations. We assessed the efficacy of several molecularly targeted agents marketed in France, which were chosen on the basis of tumour molecular profiling but used outside their indications, in patients with advanced cancer for whom standard-of-care therapy had failed. METHODS: The open-label, randomised, controlled phase 2 SHIVA trial was done at eight French academic centres. We included adult patients with any kind of metastatic solid tumour refractory to standard of care, provided they had an Eastern Cooperative Oncology Group performance status of 0 or 1, disease that was accessible for a biopsy or resection of a metastatic site, and at least one measurable lesion. The molecular profile of each patient's tumour was established with a mandatory biopsy of a metastatic tumour and large-scale genomic testing. We only included patients for whom a molecular alteration was identified within one of three molecular pathways (hormone receptor, PI3K/AKT/mTOR, RAF/MEK), which could be matched to one of ten regimens including 11 available molecularly targeted agents (erlotinib, lapatinib plus trastuzumab, sorafenib, imatinib, dasatinib, vemurafenib, everolimus, abiraterone, letrozole, tamoxifen). We randomly assigned these patients (1:1) to receive a matched molecularly targeted agent (experimental group) or treatment at physician's choice (control group) by central block randomisation (blocks of size six). Randomisation was done centrally with a web-based response system and was stratified according to the Royal Marsden Hospital prognostic score (0 or 1 vs 2 or 3) and the altered molecular pathway. Clinicians and patients were not masked to treatment allocation. Treatments in both groups were given in accordance with the approved product information and standard practice protocols at each institution and were continued until evidence of disease progression. The primary endpoint was progression-free survival in the intention-to-treat population, which was not assessed by independent central review. We assessed safety in any patients who received at least one dose of their assigned treatment. This trial is registered with ClinicalTrials.gov, number NCT01771458. FINDINGS: Between Oct 4, 2012, and July 11, 2014, we screened 741 patients with any tumour type. 293 (40%) patients had at least one molecular alteration matching one of the 10 available regimens. At the time of data cutoff, Jan 20, 2015, 195 (26%) patients had been randomly assigned, with 99 in the experimental group and 96 in the control group. All patients in the experimental group started treatment, as did 92 in the control group. Two patients in the control group received a molecularly targeted agent: both were included in their assigned group for efficacy analyses, the patient who received an agent that was allowed in the experimental group was included in the experimental group for the purposes of safety analyses, while the other patient, who received a molecularly targeted agent and chemotherapy, was kept in the control group for safety analyses. Median follow-up was 11·3 months (IQR 5·8-11·6) in the experimental group and 11·3 months (8·1-11·6) in the control group at the time of the primary analysis of progression-free survival. Median progression-free survival was 2·3 months (95% CI 1·7-3·8) in the experimental group versus 2·0 months (1·8-2·1) in the control group (hazard ratio 0·88, 95% CI 0·65-1·19, p=0·41). In the safety population, 43 (43%) of 100 patients treated with a molecularly targeted agent and 32 (35%) of 91 patients treated with cytotoxic chemotherapy had grade 3-4 adverse events (p=0·30). INTERPRETATION: The use of molecularly targeted agents outside their indications does not improve progression-free survival compared with treatment at physician's choice in heavily pretreated patients with cancer. Off-label use of molecularly targeted agents should be discouraged, but enrolment in clinical trials should be encouraged to assess predictive biomarkers of efficacy.

RESUMO

BACKGROUND: The improved survival of patients since the use of highly active antiretroviral treatments has lead to the reporting of non-AIDS defining tumors, such as lung cancer. METHODS: Analysis of the records of 22 HIV-infected patients with lung cancer (LC) diagnosed in three hospitals located in the Paris area (France). RESULTS: Twenty-one patients were smokers. The patients (86% male, 14% female) had a median age of 45 yr (range, 33-64 yr). Risk factors for HIV infection were intravenous drug use in 5 patients, homosexual transmission in 10 patients, and heterosexual transmission in 7 patients. At diagnosis of LC, seven patients had previously developed a CDC-defined AIDS manifestation, the median CD4 cell count was 364/mm3 (range 20-854/mm3) and median HIV1 RNA viral load was 3000 copies/mL. The most frequent histological subtype was squamous cell carcinoma (11 cases). A stage III-IV disease was observed in 75% of the patients. Only one patient had a small-cell lung carcinoma. Twenty-one patients received combined specific therapy, of which six patients underwent surgery for the LC. The median overall survival was 7 mo. No opportunistic infections occurred during LC therapy. CONCLUSIONS: LC occurs at a young age in HIV-infected smokers. LC is not associated with severe immunodeficiency. The prognosis is poor because of their initial extensive disease and a poor response to therapy. However, surgery appears to improve outcome in much the same way as in the general population.
