Trabectedin for sarcomas in daily clinical practice: analysis of 45 patients treated in a French institution.

INTRODUCTION: The active clinical research programme of trabectedin continues to improve knowledge on the therapeutic activity and toxicity of the drug in the treatment of soft tissue sarcomas (STS). In contrast, limited number of data is available on its use outside of clinical trials. PATIENTS AND METHODS: We retrospectively analysed efficacy and safety of trabectedin when given in daily practice to patients with advanced/recurrent STS. Outcomes were compared with previously published works including clinical and retrospective studies. RESULTS: Forty-five patients received trabectedin between January 2005 and May 2014. Sarcomas were histologically heterogeneous in our cohort (37.9% of other types of sarcomas than L-sarcomas). Our patients had poor baseline health status (ECOG ≥ 2 [17.8%]) and had received multiple previous lines of chemotherapy. Patients received a median of five cycles of treatment (1-22). The objective response rate was statistically superior in our study (37.8%) compared to the other works. However, median PFS was similar. Trabectedin-related serious adverse events (AEs) induced hospitalizations and treatment discontinuation in 22 and 15% of patients. CONCLUSION: This analysis confirms the efficacy of trabectedin in clinical practice (with a third of patients experiencing prolonged disease control) and highlighted the importance of its administration as early line therapy to allow the best management of serious AEs.

Crizotinib Associated with Ground-Glass Opacity Predominant Pattern Interstitial Lung Disease: A Retrospective Observational Cohort Study with a Systematic Literature Review.

BACKGROUND: Crizotinib, an oral tyrosine kinase inhibitor that targets anaplastic lymphoma kinase, has proven to offer sustained progression-free survival in anaplastic lymphoma kinase-rearranged non-small-cell lung cancers. Occurrence of severe interstitial lung disease (ILD) was one of the crucial adverse events reported in randomized clinical trials and case reports. METHODS: In September 2011, we observed a crizotinib-associated ILD case. Following this index case, we reviewed the clinical and computed tomographic scan features of all patients treated with crizotinib in our department, between October 2010 and July 2013, comparing patients with and without ILD. A systematic literature review was performed. RESULTS: During this period, 29 patients were treated with crizotinib, five of whom developed ILD, in addition to the index case. Two types of adverse lung reactions may be observed in patients undergoing crizotinib therapy. The first is a severe, usually fatal, ILD that occurs during the first month of treatment (n = 1). The second is a less severe ILD, occurring later in time (n = 5). It occurs gradually with only few clinical symptoms, but predominant ground-glass opacities on computed tomography, along with an intensive lymphocytic alveolitis in bronchoalveolar lavage fluid. These cases had a longer response with a median progression-free survival duration at 19.9 months (17.9-23.5) compared with 6.2 months (1.2-13.6) for controls (p = 0.04). CONCLUSION: Forty-nine cases of crizotinib-associated ILD have been identified by the systematic review of the literature, including our six cases. Two types of adverse lung reactions may be observed with different presentation, prognosis, and treatment. Their potential mechanisms should be clarified. Nine patients with the less severe form of ILD were safely retreated.

Skin toxicities compromise prolonged pemetrexed treatment.

INTRODUCTION: Pemetrexed is approved to treat non-small cell lung cancer and has an overall favorable toxicity profile. A case of pemetrexed-induced cutaneous adverse events (CAE), i.e., periorbital edema with conjunctivitis and edema of the limbs, leading to severe fluid retention, was diagnosed in our unit. The aim of this study was to evaluate the incidence and risk factors for CAEs. METHODS: Patients treated with pemetrexed were identified from a prospective cohort. To detect pemetrexed-associated CAEs, questionnaires were answered by patients and the referring oncologist. RESULTS: Included were 107 patients treated with four cycles or more of pemetrexed. Pemetrexed-induced CAEs were observed in 37 of 107 (35%) total patients (TPs) and 25 of 47 (53%) alive patients (APs). Conjunctivitis was the most frequent CAE: 27 of 107 (25%) in TPs and 21 of 47 (44%) in APs. Periorbital edema occurred in 16 of 107 (15%) TPs and 14 of 47 (30%) APs. Limb edema was present in 14 of 107 (13%) TPs and 12 of 47 (25%) APs. Only two cases of CAE influenced pemetrexed treatment. No significant differences in age, body surface area, smoking status, and performance status were detected. Patients with CAE had more cycles of pemetrexed (7 versus 5.5; p = 0.028). In univariate and multivariate analyses, gender ratio was statistically different (p = 0.031): 48% (12/25) of women in the CAE group versus only 18% (4/18) in the control group. CONCLUSION: Pemetrexed induces frequent conjunctivitis, peripheral edema, and edema of the limbs. Female gender seems to be an independent risk for CAE. CAEs are frequently disabling and symptomatic treatment should be proposed.
