Over the centuries, bio-sourced compounds isolated from plants, insects and microorganisms have been a potent source of drugs for the treatment of human diseases. In this review, we recapitulate the story of one of these compounds, 2-propylpentanoic acid, derived from the Valeriana officinalis flowering plant and its path to validation as a cancer treatment.

Summary : Non small cell lung cancer is the most frequent type of lung cancer and its prognosis is still very poor. Relapse is frequent and can be observed even in early stages of the disease, in spite of a surgical management with curative intent. This paper gives an overview of the main prognostic factors, the two most important of which remain the staging and tumor histology. These also determine the therapeutic strategy. Other factors of poor prognosis might also be useful for clinicians, particularly in their decision to refer patients for adjuvant therapies.

Objective and Importance: Yellow nail syndrome (YNS) is a rare disorder of unknown aetiology characterized by the triad of yellow nails, lymphoedema and respiratory manifestations. About 200 cases have been reported, but a lot of patients probably elude proper diagnosis because of both variability of symptoms and ignorance of this syndrome by many physicians. The pathogenesis remains unclear, and could involve functional lymphatic abnormalities, microvasculopathy or lymphocyte deficiency, but none of these hypotheses seems fully satisfactory. Clinical Presentation: We report for the first time two cases of YNS associated with multiple myeloma relapsing after non-myeloablative haematopoietic cell transplantation (HCT). In these two cases, onset or worsening of YNS symptoms followed graft-versus-host disease (GvHD) manifestations. Intervention: Corticosteroids given to treat GvHD also improved YNS manifestations. Conclusion: YNS after HCT might be a microvascular manifestation of endothelial GvHD and corticosteroids might be an effective treatment. [less ▲]

In the absence of a satisfactory treatment of malignant pleural mesothelioma (MPM), novel therapeutic strategies are urgently needed. Among these, immunotherapy offers a series of advantages such as tumor specificity and good tolerability. Unfortunately, MPM immunotherapy is frequently limited by incomplete cell differentiation or feedback loop regulatory mechanisms. In this review, we describe different components of the innate immune system and discuss strategies to improve MPM immunotherapy by using epigenetic modulators. [less ▲]

Thymic epithelial tumors (TET) are rare. Their optimal care is still poorly defined because of their rarity and of the resulting difficulty to conceive large clinical trials. This review of the literature presents the current clinical and therapeutic data on this form of tumors and underlines the need for a multidisciplinary approach to advanced stage TET. Three clinical situations can be encountered: encapsuled tumors lead to radical surgery; tumors associated with capsular invasion justify a postoperative radiotherapy; advanced stages require a multimodal treatment by chemotherapy, possibly completed by surgery and adjuvant radiotherapy. Besides systemic chemotherapies, the place of new therapeutic strategies, such as somatostatin analogues and targeted treatments, requires to be defined. Treatment of late stage TET is based upon a multidisciplinary dialogue, ideally by a reference team. [less ▲]

Already known as the first cause of mortality in men, non-small cell lung cancer (NSCLC) is nowadays a major cause of cancer-related death in women. Its approach relies on a thorough locoregional and extra-thoracic assessment allowing a precise staging which not only has prognostic value, but also determines the therapeutic options. This review presents the current multidisciplinary strategy agreement or the treatment of NSCLC. [less ▲]

As knowledge of airways disease has grown, it has become apparent that neither chronic obstructive pulmonary disease (COPD) nor asthma is a simple, easily defined disease. In the past, treatment options for both diseases were limited; thus, there was less need to define subgroups. As treatment options have grown, so has our need to predict who will respond to new drugs. To date, identifying subgroups has been largely reported by detailed clinical characterisation or differences in pathobiology. These subgroups are commonly called "phenotypes"; however, the problem of defining what constitutes a phenotype, whether this should include comorbid diseases and how to handle changes over time has led to the term being used loosely. In this review, we describe subgroups of COPD and asthma patients whose clinical characteristics we believe have therapeutic or major prognostic implications specific to the lung, and whether these subgroups are constant over time. Finally, we will discuss whether the subgroups we describe are common to both asthma and COPD, and give some examples of how treatment might be tailored in patients where the subgroup is clear, but the label of asthma or COPD is not.

Asthma is a chronic inflammatory disease that often features eosinophilia, especially in its most severe forms. Monoclonal antibodies directed towards interleukin-5, such as mepolizumab or reslizumab, were shown to be very effective at reducing blood and airways eosinophilia. When administered monthly by intravenous or subcutaneous injection in severe eosinophilic asthmatic patients, they reduce severe exacerbation rate by 50 %, improve asthma control and quality of life, and have an oral glucocorticoids sparing effect in those requiring oral corticoids as maintenance therapy.

BACKGROUND: Necitumumab is a second-generation recombinant human immunoglobulin G1 EGFR monoclonal antibody that competitively inhibits ligand binding. We aimed to compare necitumumab plus pemetrexed and cisplatin with pemetrexed and cisplatin alone in patients with previously untreated, stage IV, non-squamous non-small-cell lung cancer (NSCLC). METHODS: We did this randomised, open-label, controlled phase 3 study at 103 sites in 20 countries. Patients aged 18 years or older, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 and adequate organ function, were randomly assigned 1:1 to treatment with a block randomisation scheme (block size of four) via a telephone-based interactive voice-response system or interactive web-response system. Patients received either cisplatin 75 mg/m(2) and pemetrexed 500 mg/m(2) on day 1 of a 3-week cycle for a maximum of six cycles alone, or with necitumumab 800 mg on days 1 and 8. Necitumumab was continued after the end of chemotherapy until disease progression or unacceptable toxic effects. Randomisation was stratified by smoking history, ECOG performance status, disease histology, and geographical region. Patients and study investigators were not masked to group assignment. The primary endpoint was overall survival. Efficacy analyses were by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00982111. FINDINGS: Between Nov 11, 2009, and Feb 2, 2011, we randomly assigned 633 patients to receive either necitumumab plus pemetrexed and cisplatin (n=315) or pemetrexed and cisplatin alone (n=318). Enrolment was stopped on Feb 2, 2011, after a recommendation from the independent data monitoring committee. There was no significant difference in overall survival between treatment groups, with a median overall survival of 11.3 months (95% CI 9.5-13.4) in the necitumumab plus pemetrexed and cisplatin group versus 11.5 months (10.1-13.1) in the pemetrexed and cisplatin group (hazard ratio 1.01 [95% CI 0.84-1.21]; p=0.96). The incidence of grade 3 or worse adverse events, including deaths, was higher in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group; in particular, deaths regarded as related to study drug were reported in 15 (5%) of 304 patients in the necitumumab group versus nine (3%) of 312 patients in the pemetrexed and cisplatin group. Serious adverse events were likewise more frequent in the necitumumab plus pemetrexed and cisplatin group than in the pemetrexed and cisplatin group (155 [51%] of 304 vs 127 [41%] of 312 patients). Patients in the necitumumab plus pemetrexed and cisplatin group had more grade 3-4 rash (45 [15%] of 304 vs one [<1%] of 312 patients in the pemetrexed and cisplatin alone group), hypomagnesaemia (23 [8%] vs seven [2%] patients), and grade 3 or higher venous thromboembolic events (23 [8%] vs 11 [4%] patients) than did those in the pemetrexed and cisplatin alone group. INTERPRETATION: Our findings show no evidence to suggest that the addition of necitumumab to pemetrexed and cisplatin increases survival of previously untreated patients with stage IV non-squamous NSCLC. Unless future studies identify potentially useful predictive biomarkers, necitumumab is unlikely to provide benefit in this patient population when combined with pemetrexed and cisplatin.

Bronchial thermoplasty is a recent endoscopic technique for the treatment of severe asthma. It is an innovative treatment whose clinical efficacy and safety are beginning to be better understood. Since this is a device-based treatment, the evaluation procedure of risks and benefits is different that for pharmaceutical products; safety aspects, regulatory requirements, study design and the assessment of the magnitude of effects may all be different. The mechanism of action and optimal patient selection need to be assessed further in rigorous clinical and scientific studies. This technique is in harmony with the development of personalised medicine in the 21st century. It should be developed further in response to the numerous challenges and needs not yet met in the management of severe asthma. [less ▲]

Résumé : Le but de ce travail était d’évaluer la prévalence et de décrire les caractéristiques du phénotype mixte BPCO-asthme parmi les patients BPCO stables de stade II à IV selon la classification de GOLD. Matériel et méthodes : entre mai 2013 et avril 2014, 46 patients consécutifs furent recrutés à partir des consultations de Pneumologie du CHU de Liège. Ils étaient considérés comme présentant un syndrome mixte BPCO-asthme si leur indice de Tiffeneau était < 70% après bronchodilatation et s’accompagnait soit d’un antécédent d’asthme avant l’âge de 40 ans, soit d’au moins deux des trois critères suivants: 1) réversibilité bronchique significative (changement du VEMS après la bronchodilatation ≥ 200 ml et ≥ 12%), 2) inflammation éosinophilique: éosinophiles dans les expecto-rations ≥ 3% ou/et éosinophiles dans le sang ≥ 400/μl ou/et FENO ≥ 45 ppb, 3) histoire d’allergie respiratoire, ou IgE sériques totales ≥ 113 KU/l, ou RAST ≥ 0,35 KU/l à l’égard d’un des principaux aéroallergènes. Le phénotype mixte BPCO-asthme fut observé chez 37% des patients. L’expression symptomatique était plus marquée dans le groupe de phénotype mixte que dans le groupe de BPCO pure (CAT 24,6 ± 8,1 vs 19,4 ± 8, p < 0,05) en dépit d’un déficit spiro-métrique identique. Le coefficient de transfert alvéolo-capillaire (DLCO/VA%) était préservé dans le phénotype mixte (97 ± 24%) et supérieur à celui mesuré chez les patients BPCO pure (80 ± 20%) (p < 0,05). La prévalence du phéno-type mixte est voisine d’un tiers chez les patients BPCO et ces sujets ont une expression symptomatique plus marquée, sans signe d’obstruction bronchique plus sévère. [less ▲]
