Le cancer du sein représente chez la personne âgée une pathologie fréquente. Le choix du traitement dépend de l'âge physiologique, des pathologies et comorbidités associées ainsi que du niveau de vie et d'autonomie. De plus, selon les facteurs histopronostiques (récepteurs aux oestrogènes et à la progestérone, la surexpression du cerb-B2) on décidera éventuellement du schéma thérapeutique le plus approprié. Chez la personne âgée, la chirurgie (mastectomie ou tumorectomie), la radiothérapie et l'hormonothérapie trouvent leur place. Au-delà de 70 ans, la place de la chimiothérapie est incertaine. En effet, les patientes de plus de 70 ans sont sous-représentées dans les études randomisées. [less ▲]

18F-FDG PET imaging is now established as a valuable tool for evaluating cancer patients. However, a limitation of 18F-FDG is its absence of specificity for tumor. Both protein synthesis and amino acid transport are enhanced in most tumor cells, but their metabolism is less affected in inflammation. We therefore decided to evaluate the ability of PET with 2-18F-fluoro-L-tyrosine (18F-TYR) to visualize cancer lesions in patients compared with 18F-FDG PET. Methods: 18F-FDG PET and 18F-TYR PET were performed on 23 patients with histologically proven malignancies (11 non-small cell lung cancers (NSCLCs), 10 lymphomas, and 2 head and neck carcinomas). Fully corrected, whole-body PET studies were obtained on separate days. 18F-FDG studies were performed after routine clinical fashion. 18F-TYR studies were started 36 ± 6 min after tracer injection and a second scan centered over a reference lesion was acquired after completion of the whole-body survey-on average, 87 min after injection. Standardized uptake values (SUVs) were calculated for all abnormal foci and for various normal structures. Results were compared with pathologic or correlative studies. Results: 18F-FDG PET correctly identified 54 malignant lesions, among which 36 were also visualized with 18F-TYR (67%). 18F-TYR did not detect any additional lesion. Tumor SUVs (SUVbw, 5.2 vs. 2.5), tumor-to-muscle (7.4 vs. 2.7), and tumor-to-mediastinum activity ratios (3 vs. 1.4) were higher with 18F-FDG than with 18F-TYR. Two of 11 NSCLCs and 4 of 10 lymphomas were understaged with 18F-TYR compared with 18F-FDG. Although the NSCLC lesions missed by 18F-TYR PET were small, several large lymphoma lesions did not accumulate the tracer. In 4 patients, 18F-TYR-positive lesions coexisted with 18F-TYR-negative lesions. There was a high physiologic 18F-TYR uptake by the pancreas (average SUVbw, 10.3) and the liver (average SUVbw, 6.3). Muscle and bone marrow uptakes were also higher with 18F-TYR than with 18F-FDG: average SUVbw, 1 versus 0.7 and 2.6 versus 1.8, respectively. There was no change over time in the 18F-TYR uptake by the tumors or the normal structures. Conclusion: 18F-TYR PET is not superior to 18F-FDG PET for staging patients with NSCLC and lymphomas.

Colorectal cancer is really a public health problem. The authors review the literature about the environmental factors leading to colorectal cancer. Chemoprevention of colorectal cancer is also discussed, particularly by aspirin and non steroidal anti-inflammatory drugs. Development of specific cyclooxygenase-2 inhibitors constitutes a promising research's field. Secondary prevention by coloscopy and polypectomy must lead to a lower rate of colorectal cancer disease and improvement of mortality. [less ▲]

La radiothérapie métabolique des métastases osseuses est un traitement palliatif de la douleur. Cet objectif est rempli dans la grande majorité des cas, sans effets secondaires cliniquement ressentis par le patient. Tous les patients en dissémination osseuse ne peuvent cependant bénéficier de cette approche qui, lorsqu'elle est choisie, doit toujours être appliquée dans un cadre multidisciplinaire. Les lésions accessibles à ce traitement doivent avoir démontré leur caractère ostéocondensant en scintigraphie. La fonction rénale et la réserve médullaire sont des paramètres importants, l'élimination des radiopharmaceutiques étant urinaire et leur toxicité, médullaire. Les situations particulières telles que risque fracturaire important ou compression médullaire sont des contre-indications. Le traitement est simple dans son principe et dans sa réalisation. Il permet une amélioration très significative de la qualité de vie, tout en réalisant des économies substantielles en terme de coût de santé publique. [less ▲]

BACKGROUND: It is not known whether increasing the dose of filgrastim after mobilizing chemotherapy improves collection of peripheral blood progenitor cells (PBPC) and leads to faster hematopoietic engraftment after autologous transplantation. STUDY DESIGN AND METHODS: A randomized, open-label, multicenter trial was carried out in patients with breast cancer, multiple myeloma, and lymphoma, in which patients were randomized to receive 5 or 10 microg per kg per day of filgrastim after standard chemotherapy to mobilize PBPCs. After high-dose chemotherapy, the components from the first two leukapheresis procedures were returned, and all patients received 5 microg per kg day of filgrastim after transplantation. RESULTS: A total of 131 patients were randomized, of whom 128 were mobilized (Group A, 5 microg/kg, n = 66; Group B, 10 microg/kg, n = 62) and 112 were transplanted. Only six patients were not transplanted because of insufficient CD34+ cell numbers. The median number of CD34+ cells collected in the first two leukapheresis procedures tended to be higher in Group B than in Group A (12.0 vs. 7.2 x 10(6)/kg, NS), but after transplantation there was no significant difference in median times to platelet (9 days in both groups) or neutrophil (8 days in both groups) engraftment or the number of platelet transfusions (three in both groups). A subsequent subgroup analysis separating patients transplanted after first- or second-line chemotherapy also showed no measurable impact of filgrastim dose on the median CD34+ cell yield or on platelet engraftment in either subgroup. CONCLUSION: PBPC mobilization with chemotherapy and 5 microg per kg of filgrastim is very efficient, and 10 microg per kg of filgrastim does not provide additional clinical benefit. [less ▲]

With the emergence of positron emission tomography (PET) from research laboratories into routine clinical use, it is important to redefine the most appropriate use of each imaging technique. The aim of this review article is to show the potential of PET in oncology. We discuss the most promising indications and the perspectives for the future. We will also point out the shortcomings and the important questions to be answered before fully considering PET as a necessary tool in the day-to-day practice of oncology. Although many studies have documented the high accuracy of 18F-FDG PET for the detection and staging of malignant tumours and for the monitoring of therapy results in these patients, it is very important to assess the impact of the technique on patient outcome and to show cost-effectiveness from the societal viewpoint.

BACKGROUND: Relapse after treatment of Hodgkin's disease (HD) is usually identified as a result of the investigation of symptoms. We undertook this study to examine the value of whole-body positron emission tomography (PET) for the detection of preclinical relapse. PATIENTS AND METHODS: Thirty-six patients underwent 2-[fluorine-18]fluoro-2-deoxy-D-glucose ((18)F-FDG) PET at the end of treatment and than every 4-6 months for 2-3 years after the end of polychemotherapy and/or radiotherapy. In those cases of abnormal (18)F-FDG accumulation a confirmatory study was performed 4-6 weeks later. RESULTS: One patient had residual tumor and four patients relapsed during a follow-up of 5-24 months. All five events were correctly identified early by (18)F-FDG PET. Residual tumor or relapse was never first diagnosed based on clinical examination, laboratory findings or computed tomography (CT) studies. Two patients presented B symptoms and the three others were asymptomatic at the time of residual disease or relapse. Confirmation of residual disease or relapse was obtained by biopsy in four patients 1, 1, 5 and 9 months after PET and by unequivocal clinical symptoms and CT studies in one patient 3 months after PET. False-positive (18)F-FDG PET studies incorrectly suggested possible relapse in six other patients, but the confirmatory PET was always negative. Our study also provides important information about physiological (18)F-FDG uptake in the thymus. CONCLUSIONS: Our data suggest the potential of (18)F-FDG PET to detect preclinical relapse in patients with HD. This could help identify patients requiring salvage chemotherapy at the time of minimal disease rather than at the time of clinically overt relapse. Further studies are warranted to determine the impact of PET on treatment management and outcome. In fact, the aim of follow-up procedures is not only to detect preclinical relapse but mainly to obtain better results by starting salvage treatment earlier. A cost-benefit analysis will also be necessary before (18)F-FDG PET can be used routinely in the follow-up of patients with HD. [less ▲]

Actuellement, on arrive à guérir 70-80% des patients atteints de maladie de Hodgkin et 50% des patients atteints de lymphome non-Hodgkinien de malignité intermédiaire ou élevée. Une approche systématique concernant le diagnostic, la classification de la maladie et la détermination des facteurs pronostiques permet de choisir la thérapeutique la plus appropriée. Les auteurs passent en revue les examens à réaliser au diagnostic et discutent de la place de la tomographie à émission de positons (TEP) dans cette indication. Ils évoquent ensuite le problème des masses résiduelles. La TEP est maintenant l'examen de choix pour établir le bilan de fin de traitement. Les auteurs discutent également du rôle potentiel de la TEP pour l'évaluation thérapeutique précoce et le suivi régulier des patients après traitement pour lymphome. Enfin, l'aspect particulier des lymphomes de l'enfant est abordé. [less ▲]

Important progress has been made in the treatment of liver metastases of advanced colorectal cancer. Surgery with curative intent, when possible, shows evidence of prolonged survival. Response rate and overall survival can be improved with modern polychemotherapy. Cytotoxic drug combinations and sequential treatments sometimes make surgery possible for initially non resectable lesions. Impact of loco-regional treatment such as hepatic arterial infusion chemotherapy must be defined in randomised trials. Radiofrequency ablation is also currently evaluated in clinical trials. In this review the benefit of each treatment is discussed. [less ▲]

Purpose: Many anticancer therapies exert their therapeutic effect by inducing apoptosis in target tumors. We evaluated in a Phase I study the safety and the feasibility of Tc-99m-Annexin V for imaging chemotherapy-induced apoptosis in human cancers immediately after the first course of chemotherapy. Experimental Design: Fifteen patients presenting with lung cancer (n = 10), lymphoma (n = 3), or breast cancer (n = 2) underwent Tc-99m-Annexin V scintigraphy before and within 3 days after their first course of chemotherapy. Tumor response was evaluated by computed tomography and F-18-fluoro-2-deoxy-D-glucose positron emission tomography scans, 3 months in average after completing the treatment. Median follow-up was 117 days. Results: In all cases, no tracer uptake was observed before treatment. However, 24-48 h after the first course of chemotherapy, 7 patients who showed Tc-99m-Annexin V uptake at tumor sites, suggesting apoptosis, had a complete (n = 4) or a partial response In = 3). Conversely, 6 of the 8 patients who showed no significant posttreatment tumor uptake had a progressive disease. Despite the lack of tracer uptake after treatment, the 2 patients with breast cancer had a partial response. Overall survival and progression-free survival were significantly related to tracer uptake in treated lung cancers and lymphomas (P < 0.05). No serious adverse events were observed. Conclusions: Our preliminary results demonstrated the feasibility and the safety of Tc-99m-Annexin V for imaging apoptosis in human tumors after the first course of chemotherapy. Initial data suggest that early Tc-99m-Annexin V tumor uptake may be a predictor of response to treatment in-patients with late stage lung cancer and lymphoma. [less ▲]
