The therapeutic education program set up at the Institut Universitaire du Cancer (University Cancer Institute) in Toulouse accompanies the treatment pathway of breast cancer patients. It includes nine collective workshops. From work organization to application, professionals and patients are closely involved. © 2015 Elsevier Masson SAS. Source

Congenital infection by human cytomegalovirus (HCMV) is a leading cause of permanent sequelae of the central nervous system, including sensorineural deafness, cerebral palsies or devastating neurodevelopmental abnormalities (0.1% of all births). To gain insight on the impact of HCMV on neuronal development, we used both neural stem cells from human embryonic stem cells (NSC) and brain sections from infected fetuses and investigated the outcomes of infection on Peroxisome Proliferator-Activated Receptor gamma (PPARγ), a transcription factor critical in the developing brain. We observed that HCMV infection dramatically impaired the rate of neuronogenesis and strongly increased PPARγ levels and activity. Consistent with these findings, levels of 9-hydroxyoctadecadienoic acid (9-HODE), a known PPARγ agonist, were significantly increased in infected NSCs. Likewise, exposure of uninfected NSCs to 9-HODE recapitulated the effect of infection on PPARγ activity. It also increased the rate of cells expressing the IE antigen in HCMV-infected NSCs. Further, we demonstrated that (1) pharmacological activation of ectopically expressed PPARγ was sufficient to induce impaired neuronogenesis of uninfected NSCs, (2) treatment of uninfected NSCs with 9-HODE impaired NSC differentiation and (3) treatment of HCMV-infected NSCs with the PPARγ inhibitor T0070907 restored a normal rate of differentiation. The role of PPARγ in the disease phenotype was strongly supported by the immunodetection of nuclear PPARγ in brain germinative zones of congenitally infected fetuses (N = 20), but not in control samples. Altogether, our findings reveal a key role for PPARγ in neurogenesis and in the pathophysiology of HCMV congenital infection. They also pave the way to the identification of PPARγ gene targets in the infected brain. © 2016 Rolland et al. Source

Context: Oncocytic tumors of the adrenal cortex are rare, mostly nonfunctioning and benign. Setting: Report virilizing oncocytic adrenocortical carcinoma in a 50-year-old woman. Patient: She presented a recent and progressive virilization syndrome, associated with high blood pressure. Hormonal evaluation showed elevated serum testosterone and delta-4-androstenedione levels, normal urinary free cortisol level and incomplete suppression of cortisol at the 1 mg dexamethasone suppression test. CT scan of the abdomen revealed a 35 mm left adrenal mass. Intervention: The patient underwent a left adrenalectomy, and the histological study showed a 3 cm oncocytic adrenocortical carcinoma with signs of malignancy. Results: Immunohistochemical study revealed that tumor cells expressed the steroidogenic enzymes involved into androgen synthesis (3βHSD and P450c17α), P450 aromatase and luteinizing hormone (LH) receptors. Post-operatively, signs of virilization improved rapidly, serum testosterone and delta-4-androstenedione levels returned to normal, as did the dexamethasone suppression test. During follow-up CT-scan and 18-FDG PET/CT showed a right ovary mass, corresponding to a follicular cyst associated with hyperthecosis. The patient is alive with no recurrence 48 months after adrenal surgery. Conclusion: Oncocytic adrenocortical carcinomas, although extremely rare, should be considered in women with a virilization syndrome. In this woman immunohistochimical studies revealed the presence of steroidogenic enzymes involved into androgen synthesis and aromatization, and LH receptors could be implicated in this pathology. © 2016 Taylor & Francis.

The optimal management of patients with relapsed chronic lymphocytic leukemia (CLL) is dictated by the type of prior therapy, duration of prior response, presence of genomic aberrations, age, and comorbidities. The patterns of relapses and the clinical outcomes of second-line options after fludarabine-cyclophosphamide-rituximab (FCR) is given as a frontline treatment are currently unknown. In this retrospective and non-randomized study, we report the outcomes of 132 patients from databases of 14 French CLL study group centers who needed a second-line treatment after FCR frontline. Bendamustine+rituximab (BR) was the most frequently used second-line regimen, followed by alemtuzumab-based regimens, R-CHOP, and FCR. Median progression-free survival (PFS) was 18 months after BR with a median overall survival (OS) not reached. We also found that response durations of<36 months and the presence of del(17p) are critical factors that contribute to poor overall survival. BR appears to be an effective salvage regimen in our series, both in terms of progression-free and overall survival. Patients who relapsed less than 36 months after FCR have a poor outcome, not significantly different in this study from patients with early relapses less than 12 or 24 months. © 2015 Wiley Periodicals, Inc.

Background: To assess impact of surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients treated for a first relapse of ovarian cancer (FROC). Patients and Methods: Patients with a FROC treated with second-line chemotherapy, surgery and HIPEC were retrospectively included from 13 Institutions. Studied parameters were interval free between the end of initial treatment and the first relapse, second-line chemotherapy, peritoneal cancer index and completeness of surgery, HIPEC, mortality and morbidity, pathological results and survival. Results: From 2001 to 2010, 314 patients were included. The main strategy was secondary chemotherapy followed by surgery and HIPEC (269/314- 85.6%). Mortality and morbidity rates were respectively 1% and 30.9%. Median follow-up was 50 months, 5-year overall survival was 38.0%, with no difference between platinum-sensitive or -resistant patients and 5-year disease-free survival was 14%. Conclusion: HIPEC allows encouraging survival in the treatment of FROC, better in case of complete surgery, with acceptable mortality and morbidity rates. Source
