    To assess the efficacy of the combination of long-acting release (LAR) octreotide and tamoxifen (TMX) for the treatment of advanced hepatocellular carcinoma (HCC). A total of 109 patients with advanced HCC were randomised to receive octreotide LAR combined with TMX (n=56) (experimental treatment group) or TMX alone (n=53; control group). The clinical, biological and tumoural parameters were recorded every 3 months until death. Primary end point was patient survival; secondary end points were the impact of therapy on tumour response, quality of life and variceal bleeding episodes. Univariate and multivariate analyses were performed for assessment of specific prognostic factors. The median survival was 3 months (95% CI 1.4–4.6) for the experimental treatment group and 6 months (CI 95% 2–10) for the control group (P=0.609). There was no difference in terms of α-foetoprotein (α-FP) decrease, tumour regression, improvement of quality of life and prevention of variceal bleeding between the two groups. Variables associated with a better survival in the multivariate analysis were: presence of cirrhosis, α-FP level <400 ng ml−1 and Okuda stage I. The combination of octreotide LAR and TMX does not influence survival, tumour progression or quality of life in patients with advanced HCC

    Background Pazopanib is a multitargeted tyrosine kinase inhibitor approved for the treatment of patients with selective subtypes of advanced soft tissue sarcoma (STS) who have previously received standard chemotherapy including anthracyclines. Data on the efficacy in vascular sarcomas are limited. The main objective of this study was to investigate the activity of pazopanib in vascular sarcomas.Patients and methods A retrospective study of patients with advanced vascular sarcomas, including angiosarcoma (AS), epithelioid hemangioendothelioma (HE) and intimal sarcoma (IS) treated with pazopanib in real life practice at EORTC centers as well as patients treated within the EORTC phase II and III clinical trials (62043/62072) was performed. Patient and tumor characteristics were collected. Response was assessed according to RECIST 1.1. and survival analysis was performed.Results Fifty-two patients were identified, 40 (76.9%), 10 (19.2%) and two (3.8%) with AS, HE and IS, respectively. The response rate was eight (20%), two (20%) and two (100%) in the AS, HE and IS subtypes, respectively. There was no significant difference in response rate between cutaneous and non-cutaneous AS and similarly between radiation-associated and non-radiation-associated AS. Median progression-free survival (PFS) and median overall survival (OS; from commencing pazopanib) were three months (95% CI 2.1-4.4) and 9.9 months (95% CI 6.5-11.3) in AS, respectively.Conclusion The activity of pazopanib in AS is comparable to its reported activity in other STS subtypes. In this study, the activity of pazopanib was similar in cutaneous/non-cutaneous and in radiation/non-radiation-associated AS. In addition, pazopanib showed promising activity in HE and IS, worthy of further evaluation

    Doxorubicin plus dacarbazine, doxorubicin plus ifosfamide, or doxorubicin alone as a first‐line treatment for advanced leiomyosarcoma: A propensity score matching analysis from the European Organization for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group

    Background The optimal treatment for advanced leiomyosarcoma is still debated. Given histotype‐specific prospective controlled data lacking, this study retrospectively evaluated doxorubicin plus dacarbazine, doxorubicin plus ifosfamide, and doxorubicin alone as first‐line treatments for advanced/metastatic leiomyosarcoma treated at European Organization for Research and Treatment of Cancer Soft Tissue and Bone Sarcoma Group (EORTC‐STBSG) sites. Methods The inclusion criteria were a confirmed histological diagnosis, treatment between January 2010 and December 2015, measurable disease (Response Evaluation Criteria in Solid Tumors 1.1), an Eastern Cooperative Oncology Group performance status ≀2, and an age ≄ 18 years. The endpoints were progression‐free survival (PFS), overall survival (OS), and overall response rate (ORR). PFS was analyzed with methods for interval‐censored data. Patients were matched according to their propensity scores, which were estimated with a logistic regression model accounting for histology, grade, age, sex, performance status, tumor site, and tumor extent. Results Three hundred three patients from 18 EORTC‐STBSG sites were identified. One hundred seventeen (39%) received doxorubicin plus dacarbazine, 71 (23%) received doxorubicin plus ifosfamide, and 115 (38%) received doxorubicin. In the 2:1:2 propensity score–matched population (205 patients), the estimated median PFS was 9.2 months (95% confidence interval [CI], 5.2‐9.7 months), 8.2 months (95% CI, 5.2‐10.1 months), and 4.8 months (95% CI, 2.3‐6.0 months) with ORRs of 30.9%, 19.5%, and 25.6% for doxorubicin plus dacarbazine, doxorubicin plus ifosfamide, and doxorubicin alone, respectively. PFS was significantly longer with doxorubicin plus dacarbazine versus doxorubicin (hazard ratio [HR], 0.72; 95% CI, 0.52‐0.99). Doxorubicin plus dacarbazine was associated with longer OS (median, 36.8 months; 95% CI, 27.9‐47.2 months) in comparison with both doxorubicin plus ifosfamide (median, 21.9 months; 95% CI, 16.7‐33.4 months; HR, 0.65; 95% CI, 0.40‐1.06) and doxorubicin (median, 30.3 months; 95% CI, 21.0‐36.3 months; HR, 0.66; 95% CI, 0.43‐0.99). Adjusted analyses retained an effect for PFS but not for OS. None of the factors selected for multivariate analysis had a significant interaction with the received treatment for both PFS and OS. Conclusions This is the largest retrospective study of first‐line treatment for advanced leiomyosarcoma. In the propensity score–matched population, doxorubicin and dacarbazine showed favorable activity in terms of both ORR and PFS and warrants further evaluation in prospective trials

    Receptor Tyrosine Kinases in Osteosarcoma: 2019 Update

    Get PDF
    The primary conclusions of our 2014 contribution to this series were as follows: Multiple receptor tyrosine kinases (RTKs) likely contribute to aggressive phenotypes in osteosarcoma and, therefore, inhibition of multiple RTKs is likely necessary for successful clinical outcomes. Inhibition of multiple RTKs may also be useful to overcome resistance to inhibitors of individual RTKs as well as resistance to conventional chemotherapies. Different combinations of RTKs are likely important in individual patients. AXL, EPHB2, FGFR2, IGF1R, and RET were identified as promising therapeutic targets by our in vitro phosphoproteomic/siRNA screen of 42 RTKs in the highly metastatic LM7 and 143B human osteosarcoma cell lines. This chapter is intended to provide an update on these topics as well as the large number of osteosarcoma clinical studies of inhibitors of multiple tyrosine kinases (multi-TKIs) that were recently published

    International audienceThe fossil locality of "La Borie" has revealed a unique fauna in the early Eocene of Southern France. This preliminary study has identified 35 vertebrate taxa, including some never found before in the South of France (the crocodile Kentisuchus), Southern Europe (the tillodont Plesiesthonyx) or the western part of Eurasia (the wading bird Eogrus). A new genus of creodont, a new primate and probably a new species of Neochelys are identified. Abundant material relating to the ceratomorph Lophiaspis and the giant groundbird Gastornis is reported. The sedimentological, floral and faunal data provide a paleoenvironment of floodplain savannah with a humid tropical climate, with a weakly marked dry season. An age close to the MP 8+9 reference level is proposed, based on the presence of several taxa characteristic of the earliest Eocene.Le gisement de La Borie a livrĂ© une faune unique dans l'ÉocĂšne infĂ©rieur du Sud de la France. Cette Ă©tude prĂ©liminaire y reconnaĂźt 35 taxons de vertĂ©brĂ©s, dont certains inĂ©dits pour le Sud de la France (le crocodile Kentisuchus), le Sud de l'Europe (le tillodonte Plesiesthonyx) ou la partie occidentale du continent eurasiatique (l'Ă©chassier Eogrus). Un nouveau genre de crĂ©odonte, de primate, et vraisemblablement une nouvelle espĂšce de Neochelys sont identifiĂ©s. Un matĂ©riel abondant du cĂ©ratomorphe Lophiaspis et de l'oiseau gĂ©ant Gastornis est signalĂ©. Les donnĂ©es sĂ©dimentologiques, faunistiques et floristiques convergent pour proposer un palĂ©oenvironnement de savane arborĂ©e de plaine alluviale en climat tropical humide, avec une saison sĂšche peu marquĂ©e. Plusieurs taxons militent en faveur d'un Ăąge proche du niveau-repĂšre mammalien MP 8+9
