Parthenolide (PT) is a sesquiterpene lactone isolated from Tanacetum parthenium. In this study, PT showed varying cytotoxic effects against different solid tumor cell lines. HCT116 (p53+/+) colon carcinoma cells and their parental HCT116 knockout p53 (p53-/-) cell lines showed a resistance degree of 2.36. On the other hand, wild-type U87.MG cells or cells transfected with a deletion-activated EGFR cDNA (U87.MGΔEGFR) exhibited slight sensitivity toward PT. Multidrug-resistant MDA-MB-231-BCRP cells were even more sensitive toward PT than sensitive MDA-MB-231-pcDNA cells with a resistance degree of 0.07 (collateral sensitivity). To the best of our knowledge, hypersensitivity (collateral sensit…

Objective: Radical prostatectomy (RP) is a frequent treatment for men suffering from localized prostate cancer (PCa). Whilst offering a high chance for cure, it does not come without a significant impact on health-related quality of life. Herein we review the common adverse effects RP may have over the course of time.Methods: A collaborative narrative review was performed with the identification of the principal studies on the topic. The search was executed by a relevant term search on PubMed from 2010 to February 2021.Results: Rates of major complications in patients undergoing RP are generally low. The main adverse effects are erectile dysfunction varying from 11 to 87% and urinary incont…
Phase Ib Trial Trial of Rg7116, a Glycoengineered Monoclonal Antibody Targeting Her3, in Combination with Cetuximab or Erlotinib in Patients with Adv…
2014
ABSTRACT Aim: To evaluate the safety profile of RG7116 in combination with cetuximab or erlotinib. Methods: Patients (pts) with advanced or metastatic carcinomas with centrally confirmed HER3 protein expression were included. RG7116 plus cetuximab (400 mg/m2 followed by 250 mg/m2 qw IV) and RG7116 plus erlotinib (150 mg/day p.o.) combinations were evaluated in a dose escalation study with “3 + 3” design at a starting dose of 400 mg IV of RG7116 in a q2w regimen. Results: Twenty-seven pts were enrolled in 5 cohorts (400 to 2000 mg) in the cetuximab arm. One dose-limiting toxicity (DLT) of grade 3 dehydration was reported in the 800-mg cohort. Twenty-seven pts were enrolled in 4 cohorts (400 …
Prognostic factors in the treatment of Ewing's sarcoma
1987
From 1981 up to February 1985, a total of 93 protocol patients entered the study CESS 81. The protocol recommended an initial 18-week period of polychemotherapy (VACA) followed by local therapy and two additional cycles of chemotherapy. Local therapy consisted either of radical surgery or of incomplete resection plus postoperative irradiation with 36 Gy or of radiotherapy alone (46 and 60 Gy). Centrally located lesions were always irradiated with 60 Gy. This article summarizes the data after 5 years. Data of 93 patients were analysed in October 1986 after a median follow-up of 37 months. The projected 5-year survival is 50%. The relapse rate was 42%, distant relapses occurred in 19%, local …
Abstract 2141: Stromal SPARC deficiency skews prostate cancer toward neuroendocrine differentiation
2018
Abstract Tumor progression is a multifaceted process in which, complex interactions between tumor and different types of stromal cells and extracellular matrix components, actively contribute to its phenotypic heterogeneity. Among extracellular matrix proteins, secreted protein acidic and rich in cysteine (SPARC) has been deeply studied since conflicting reports have described its expression to be either increased or decreased in different cancer settings, also depending on whether it is produced by the neoplasm or by the neighboring stroma. Nevertheless, the different contribution of tumor- or stromal-derived SPARC in prostate tumor microenvironment has not been addressed at least for tumo…
Les cancers du rein non à cellules claires : caractéristiques clinico-biologiques et prise en charge thérapeutique hors chirurgie
2020
Resume Les cancers du rein non a cellules claires representent pres de 25 % de l’ensemble des cancers du rein, et constituent un groupe de tumeurs tres heterogenes a la fois en termes de varietes histologiques, mais egalement d’anomalies biologiques oncogeniques. La presentation clinique ainsi que le pronostic des patients sont egalement tres variables. Compte tenu de la rarete de chaque entite tumorale, il n’existe que tres peu d’essais cliniques ayant porte sur une variete bien definie de cancer non a cellules claires. Ceci rend difficile l’interpretation de ces etudes, et donc l’emission de recommandations claires de prise en charge medicale pour la maladie avancee. Dans cet article, les…
Abstract A02: Neuroblastoma patient-derived orthotopic xenografts: Clinically relevant models for drug testing
2016
Abstract Widespread metastasis is a major problem for the treatment of high-risk neuroblastoma. Relevant neuroblastoma animal models are hence needed to study and target high-risk metastatic neuroblastoma. We developed neuroblastoma patient-derived orthotopic xenografts (PDXs) using viably cryopreserved or fresh patient neuroblastoma fragments which were implanted orthotopically into immunodeficient NSG mice. Immunohistochemistry showed that PDXs retain neuroblastoma markers and a highly infiltrative growth pattern. Importantly, we found distant metastasis to lungs, liver and bone marrow. Single nucleotide polymorphism array analysis confirmed that PDXs maintain patient-specific chromosomal…
L’échographie pulmonaire : une aide au diagnostic et au contrôle de la réponse à la kinésithérapie. À propos d’un cas
2017
Introduction L’echographie pulmonaire pourrait etre un outil interessant pour le kinesitherapeute puisqu’elle pourrait permettre d’ameliorer l’indication et le suivi du traitement par kinesitherapie respiratoire [1] . A notre connaissance, aucune etude n’a evalue l’impact de l’echographie pulmonaire sur le processus de decision clinique du kinesitherapeute. Ce rapport de cas aborde l’interet de l’echographie pulmonaire en kinesitherapie respiratoire chez une patiente avec une consolidation pulmonaire. Materiel, population et methode Ce rapport de cas est ecrit suivant les recommandations de « The CARE guideline » [2] . La patiente etait une femme de 68 ans, non intubee et hospitalisee dans …
Allogeneic Stem Cell Transplant Versus Tandem High-Dose Melphalan for Front-Line Treatment of Deletion 13q14 Myeloma – An Interim Analysis of the Ger…
2009
Abstract Abstract 51 Background Allogeneic stem cell transplantation (allo SCT), a treatment modality based on transfer of immunocompetent donor lymphocytes offers curative potential to subjects with a variety of hematological cancers. In multiple myeloma (MM), high-dose melphalan followed by autologous stem cell transplantation (auto SCT) is adopted as a standard of care. However, it remains palliative since virtually all patients (pts) relapse and renders allo SCT an option of interest. Deletion of chromosome 13q14 (13q-) in MM has been shown to negatively impact prognosis. Therefore, improvement of therapy for 13q- pts is highly desirable. Patients and methods A prospective two-arm multi…
