RESUMO

Medulloblastoma is a cerebellar grade IV tumour according to the WHO classification, mainly seen in children under the age of 15. This cancer can nevertheless occur in adults. We report the case of a 22-year-old patient with a medulloblastoma disseminated in the spine. The patient had a type 1 Arnold-Chiari malformation causing hydrocephalus treated by ventriculoperitoneal shunt. The current condition began with perineal and lower limb hypoesthesia, ataxic gait, erectile dysfunction and urinary incontinence. Subsequently, a predominant paraparesis of the right lower limb appeared. The patient was treated according to the PNET HR+5 protocol combining two courses of conventional chemotherapy followed by two courses of high-dose chemotherapy with autograft recovery. Given the excellent response, a proton therapy was then delivered to the whole cerebrospinal axis with boosts to the primary tumour sites. The case of this young adult patient shows on the one hand an atypical presentation, and on the other hand underlines, in the absence of a specific therapeutic strategy established for adults, the importance of collaboration between the adult and pediatric oncology departments, with management integrating innovations such as proton therapy and molecular typing.


Le médulloblastome est une tumeur cérébelleuse de grade IV selon l'Organisation Mondiale de la Santé, principalement observée chez les enfants de moins de 15 ans. Ce cancer peut néanmoins survenir chez l'adulte. Nous rapportons le cas d'un patient de 22 ans présentant un médulloblastome disséminé au niveau du rachis. Le patient est porteur d'une malformation d'Arnold-Chiari de type 1 provoquant une hydrocéphalie traitée par dérivation ventriculo-péritonéale. L'affection actuelle a débuté par une hypoesthésie du périnée et des membres inférieurs, une démarche ataxique, un trouble érectile et des troubles vésico-sphinctériens. Par la suite est apparue une paraparésie prédominant au membre inférieur droit. Le patient a été traité selon le protocole pédiatrique PNET HR+5 combinant deux cures de chimiothérapie conventionnelle suivies de deux cures de chimiothérapie à haute dose avec rattrapage par autogreffe. Vu l'excellente réponse, une protonthérapie a été administrée sur l'axe cérébrospinal avec surdosages sur les sites primaires de la tumeur. Le cas de ce jeune adulte illustre, d'une part, une présentation atypique et d'autre part, souligne, en l'absence de stratégie thérapeutique spécifique établie pour l'adulte, l'importance de la collaboration entre les services d'Oncologie adulte et pédiatrique, la prise en charge intégrant les innovations telles que la protonthérapie et le typage moléculaire.

RESUMO

As the prevalence of cancers increases with age, some elderly patients are confronted with multiple tumoural pathologies. The clinical case of a 70-year-old patient with adenocarcinoma of the breast and multiple myeloma complicated by severe renal failure illustrates the complexity of oncogeriatric management. The geriatric assessment makes it possible to detect frailty and provides assistance in the development of a personalized care plan while respecting the quality of life.


Comme la prévalence des cancers augmente avec l'âge, certains patients âgés se trouvent confrontés à plusieurs pathologies tumorales. Ce cas clinique d'une patiente de 70 ans, avec un adénocarcinome du sein et un myélome multiple compliqué d'une insuffisance rénale sé-vère, illustre la complexité de la prise en charge oncogériatrique. En effet, l'évaluation gériatrique permet de dépister la fragilité et apporte une aide à l'élaboration d'un plan de soins personnalisé en respectant la qualité de vie.

RESUMO

There is increasing interest in the role that manipulability plays in processing objects. To date, Magnié, Besson, Poncet, and Dolisi's (2003) manipulability ratings, based on the degree to which objects can be uniquely pantomimed, have been the reference point for many studies. However, these ratings do not fully capture some relevant dimensions of manipulability, including whether an object is graspable and the extent to which functional motor associations above and beyond graspability are present. To address this, we collected ratings of these dimensions, in addition to ratings of familiarity and age of acquisition (AoA), for a set of 320 black-and-white photographs of objects. Familiarity and AoA ratings were highly correlated with previously reported ratings of the same dimensions (r = .853, p < .001, and r = .771, p < .001, respectively), validating the present norms. Grasping and functional use ratings, in contrast, were more moderately correlated with Magnié et al.'s pantomime manipulability ratings (r = .507, p < .001). These results were taken as evidence that the new manipulability ratings collected in this research capture distinct aspects of object manipulability.

RESUMO

Forty-six previously untreated patients with advanced breast cancer were eligible for the present randomised phase I study. It aimed to evaluate the toxicity and activity of a therapeutic sequence with epirubicin on day 1 followed by paclitaxel on day 2 (sequence A) or the reverse sequence, ie., paclitaxel on day 1 followed by epirubicin on day 2 (sequence B). The starting doses of epirubicin and paclitaxel, administered either according to sequence A or B, (level 1 cohort) were 90 mg/m2 and 175 mg/m2, respectively. Per cohort of 3 patients, the dose of paclitaxel was increased by 25 mg/m2 (levels 2 and 4) and of epirubicin by 10 mg/m2 (levels 3 and 5). Treatment was repeated with 3-week intervals. The maximal tolerated dose (MTD) was achieved at level 1 in sequence B (paclitaxel first) and level 3 (epirubicin 100 mg/m2 followed by paclitaxel 200 mg m2) in sequence A. Dose limiting toxicity (DLT) was neutropenia (+/- febrile) in both sequences. Cardiac events occurred in 28% of the patients; significant decrease in left ventricular ejection function (LVEF) was observed in 8/33 and in 2/13 patients in sequence A and B, respectively. This was associated with 5 and 1 cardiac heart failure (CHF), respectively. In 43 evaluable patients, 10 CR and 25 PR were observed (overall response rate 81%). In the 20 patients with locally advanced disease (LABC), the respective numbers were 7 CR and 11 PR; in the 23 metastatic (MBC) patients, 3 CR and 14 PR were recorded. The median survival of the both groups was not reached at 33 + months. In conclusion , the combination of epirubicin and paclitaxel has significant activity in breast cancer. The recommended sequence of both drugs in combination therapy, mainly to avoid neutropenia, is epirubicin day 1 followed by paclitaxel on day 2. Cardiac toxicity remains problematic in either sequence of administration.

RESUMO

BACKGROUND AND OBJECTIVES: It may be useful to reduce the exposure of transplant recipients to homologous blood. This may be achieved by procuring donor-derived red blood cell (RBC) units, collecting more peripheral blood progenitor cells (PBPC) with a combination of granulocyte colony-stimulating factor (G-CSF) + recombinant human erythropoietin (rHuEpo) and by administering rHuEpo post-transplantation. DESIGN AND METHODS: Eight ABO-compatible donors were treated with rHuEpo and intravenous iron to collect 12 RBC units for use in their recipients. PBPC were collected after mobilization with rHuEpo and G-CSF in the same donors. The recipients received G-CSF and rHuEpo post-transplantation. A control group of 10 donor/recipient pairs received G-CSF alone for PBPC mobilization and after the transplantation. RESULTS: Eighty-six out of 91 planned RBC units were collected in the donors without significant decrease in hematocrit because of a 4-fold increase in RBC production despite functional iron deficiency. After 2 leukaphereses, the cumulative yields of NC and CFU-GM were lower in the study group while those of BFU-E, CFU-Mix and CD34+ cells were similar. However, erythroid recovery was significantly accelerated in the study group. INTERPRETATION AND CONCLUSIONS: Collection of 12 RBC units within 6 weeks is feasible with rHuEpo and intravenous iron; this strategy allows a dramatic reduction in recipient exposure to homologous blood; rHuEpo has no synergistic effect with G-CSF for mobilization of PBPC in normal donors and may even be deleterious; and rHuEpo in the recipient may enhance erythroid engraftment.

RESUMO

The administration of cyclosporin A (CyA) after autologous haematopoietic stem cell transplantation (HSCT) induces a systemic autoimmune syndrome mimicking graft-vs.-host disease (GVHD). This syndrome, termed autologous GVHD has notable anti-tumour activity in animal studies. We intended to induce autologous GVHD with CyA in patients undergoing an autologous HSCT. We prospectively studied 118 patients with miscellaneous malignancies undergoing an autologous HSCT with low-dose CyA to characterize the clinical syndrome, its frequency and clinical course, and to determine the factors affecting its incidence. Patients received CyA from d -1 through to d 28, first starting at 2 mg/kg intravenously and then orally as soon as feasible. The dose was adjusted to achieve pre-dose blood levels around 100 ng/ml. A skin biopsy was performed when a skin rash was observed. Thirty-three percent of the patients developed clinical GVHD: clinical stage 1 in 21 patients, stage 2 in seven patients, and stage 3 in three patients. Although total body irradiation (TBI) or high-dose cyclophosphamide were previously thought to be needed, autologous GVHD occurred in five out of 12 patients (42%) after a preparative regimen with high-dose melphalan alone. Autologous GVHD was significantly more frequent in patients older than 33 years, in patients who had received high doses of granulocyte-macrophage colony forming units (CFU-GM) and in those with a diagnosis of myeloid malignancy, compared with those with lymphoid malignancies or solid tumours. A significant negative association was also found with HLA-DR6. In lymphoma patients, GVHD occurred more frequently in advanced disease than in first or second complete remission (CR1-2) patients. All other factors studied were not predictive for GVHD. In conclusion, CyA-induced GVHD is reproducibly and safely induced with doses of CyA adapted to achieve blood levels around 100 ng/ml. In retrospective analysis, there was no survival advantage for patients with GVHD. Phase III trials with this approach are needed to evaluate its anti-tumoral effect.

RESUMO

BACKGROUND: Bone marrow transplantation with minor ABO incompatibility may be followed by moderate delayed hemolysis of the recipient's red cells by donor-derived ABO antibodies. This reaction may be more severe after transplantation of peripheral blood progenitor cells (PBPCs). CASE REPORT: A 16-year-old boy underwent an allogeneic PBPC transplant from his HLA-mismatched mother as treatment for acute myeloblastic leukemia that had proved resistant to induction chemotherapy. Transfusion of the unmanipulated PBPCs proceeded without any complication, despite the difference in ABO blood group (donor, O Rh-positive; recipient, A Rh-positive). On Day 7, a rapid drop in hemoglobin to 4 g per dL was observed, which was attributed to a massive hemolysis. All the recipient's group A red cells were destroyed within 36 hours. This delayed and rapidly progressive hemolytic anemia was not associated with the transfusion of the donor's plasma. Rather, the anti-A titer increased in parallel with marrow recovery, which suggested an active synthesis of these antibodies by immunocompetent cells from the donor against the recipient's red cells. The mother's anti-A titer was retrospectively found to be 2048. Her unusually high titer is probably due to prior sensitization during pregnancies. On Day 12, the patient developed grade IV graft-versus-host disease, which proved resistant to all treatments instituted and led to his death on Day 35. CONCLUSION: PBPC transplantation with minor ABO incompatibility may be associated with significant risk of massive delayed hemolysis.

RESUMO

Adenomatoid cystic malformations of the lung are usually diagnosed during the perinatal period. Its occurrence in adults is rare, this being the fifth case reported in literature. Improved follow-up techniques and in utero treatment have considerably improved prognosis. Differential diagnosis of pulmonary cysts should thus include this entity at all ages. Recurrent infection is usually the inaugural sign although all neighboring organs, including the heart, may be involved due to compression or extension of the inflammation. Clinical diagnosis is suggested by radiographic findings and is confirmed at pathology as surgery is generally indicated.

RESUMO

Between two groups of parameters (6 cutaneous and 5 bony), canonical correlations are calculated. The first only is generally retained (0.93 in men and 0.96 in women). They lead to the calculation of new parameters ("explained"), allowing to situate the subjects and to estimate theirs relationships.
