Osteosarcoma metastatic to the kidney and iatrogenic hemorrhage.

A 16-year old female presented painful masses in the lumbar region 5 years after the initial diagnosis of a localized osteosarcoma of the tibia. Abdominal X-ray revealed calcified masses. A bone scan confirmed an increased uptake in the renal areas. An ultrasound-guided fine needle biopsy confirmed the diagnosis of metastases. The procedure was complicated by subcapsular hemorrhage and gross hematuria. Renal metastases from osteosarcoma are usually asymptomatic and invisible on abdominal X-rays. The diagnosis is generally established by radionuclide bone scan or abdominal CT-scan. Our observation suggests that histological documentation of these unusual clinical presentations should be carefully weighed against the risk of the procedure.

Impact of high-dose busulfan plus melphalan as consolidation in metastatic Ewing tumors: a study by the Société Française des Cancers de l'Enfant.

PURPOSE: To improve the prognosis for patients with metastatic Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) using conventional chemotherapy and consolidation high-dose chemotherapy (HDCT) containing busulfan and melphalan. PATIENTS AND METHODS: Ninety-seven unselected patients with newly diagnosed metastatic ES/PNET received induction chemotherapy that included five cycles of cyclophosphamide 150 mg/m2/d for 7 days, doxorubicin 35 mg/m2/d once, followed by two cycles of ifosfamide 1.8 g/m2/d for 5 days, and etoposide 100 mg/m2/d for 5 days. Patients in complete or very good partial remission received HDCT with busulfan total dose 600 mg/m2 and melphalan 140 mg/m2 followed by autologous blood stem cells. Local therapy (surgery and/or radiation therapy) was performed before or after HDCT. RESULTS: Ninety-seven patients were enrolled from 1991 to 1999 (median age, 12.3 years; range, 0.2 to 25 years). Among them, 75 received HDCT. The 5-year event-free survival (EFS) rate for all 97 patients was 37% and the overall survival (OS) rate was 38%. The EFS after HDCT was 47%. The EFS for the 44 patients with lung-only metastases was 52%, whereas it was 36% for patients with bone metastases without bone marrow involvement. Among the 23 patients with bone marrow metastases, only one survived. The multivariate analysis for both EFS and for OS identified three independent prognostic factors: age, fever at diagnosis, and bone marrow involvement. CONCLUSION: Compared with conventional chemotherapy, HDCT may yield benefits for patients with lung-only metastases or bone metastases. These results warrant confirmation in a randomized trial and provide part of the background data for the ongoing Euro-Ewing study.

Impact of TBI on late effects in children treated by megatherapy for Stage IV neuroblastoma. A study of the French Society of Pediatric oncology.

PURPOSE: To determine the contribution of total body irradiation (TBI) to late sequelae in children treated with high-dose chemotherapy and autologous bone marrow transplantation for Stage IV neuroblastoma. PATIENTS AND METHODS: We compared two populations that were similar with regard to age, stage, pre-autologous bone marrow transplantation chemotherapy (CT) regimen, period of treatment, and follow-up (12 years). The TBI group (n = 32) received TBI as part of the megatherapy procedure (1982-1993), whereas the CT group (n = 30) received conditioning without TBI (1985-1992). Analysis 12 years later focused on growth, weight and corpulence (body mass index) delay; hormonal deficiencies; liver, kidney, heart, ear, eye, and dental sequelae; school performance; and the incidence of secondary tumors. RESULTS: Impact of TBI was most marked in relation to growth and weight delay, although the mean delay was not severe, probably because of treatment with growth hormones. Other consequences of TBI were thyroid insufficiency, cataracts, and a high incidence of secondary tumors. Hearing loss and dental agenesis were more prominent in the group treated with CT alone. No differences were observed in school performance. CONCLUSION: The most frequent side effects of TBI were cataracts, thyroid insufficiency, and growth delay, but more worrying is the risk of secondary tumors. Because of the young mean age of patients and the toxicity of TBI regimens without any survival advantage, regimens without TBI are preferable in the management of Stage IV neuroblastoma.

Medical practices and cancer care networks: examples in oncology.

Understanding medical practices or the whys and wherefores of care decision-making is among the major objectives of medical, economic and sociological research in the current political environment. Although variations of medical practice have long been known to exist, causes and deciding factors remain obscure. This is one of the reasons why medical auditing became widely used in the past years. Using methods similar to those of clinical research, we will explore existing medical practices and their implications, with the aim to propose possible improvements. Elaborating clinical practice guidelines and promoting cancer network activities might prove promising and have a significant impact on clinical practice. This article provides a state-of-the-art overview of the subject, notably in the domain of oncology where substantial advances are being made.

[Immunotherapy of poor-prognosis neuroblastoma in children: from bench to bedside].

During the last two decades, improvements in the induction and consolidation treatment phases in patients with high-risk neuroblastoma have not translated into significant increases in survival rates. Efforts to improve outcome have used high-dose chemotherapy with stem cell rescue and more recently, differentiating (retinoids) and antiangiogenic agents. In parallel, immunotherapy has become an increasingly important part of the treatment of high-risk neuroblastoma. We review here the biological concepts underlying these new approaches and their clinical applications, with a particular emphasis on applications that manipulate the immune system, including monoclonal antibodies, gene-modified tumor cells (vaccines) or immune effectors.

[Rectal cancer Information dedicated to cancer patients and relatives].

In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program. The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information, developed in this program, is based on clinical practice guidelines produced by the FNCLCC and the twenty French regional cancer centres, the National League against Cancer, The National Cancer Institute, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and caregivers. The handbook SOR SAVOIR PATIENT Understanding rectal cancer is an adapted version of the clinical practice guidelines (CPG) Standards, Options and Recommendations for rectal cancer. It is meant to provide a basis for the explanation of the disease and treatments and to facilitate discussions with the healthcare team. It is available from the FNCLCC (101, rue de Tolbiac, 75013 Paris, Tel. (0033) 1 44 23 04 68, www.fnclcc.fr). This document has been validated at the end of 2004 and published in 2005. SOR SAVOIR PATIENT guides are systematically updated when new research becomes available. Information leaflets, extracted from the handbook SOR SAVOIR PATIENT Understanding rectal cancer and published in this edition of the Bulletin du cancer, allow patients to better understand colonoscopy and colostomy, which represent an important patient information need. These articles are meant to inform patients and relatives about the disease and its treatments. It also offers health professionals a synthetic evidence-based patient information source which facilitates discussions with the patient.

[An interactive and evolutive software program to personalize treatment schedule : implication on daily life: the Centre Léon Bérard experience].

The second plan against cancer, initiated by the French President in 2003, has introduced a two-step procedure to announce cancer to the patient. During initial visit, the doctor tells the patient about his disease. On the second visit, the doctor elaborates the treatment strategy and proposes an individualized treatment plan for each patient. The objective of this plan is to offer to patients and caregivers an accurate, precise and personalized treatment schedule. The Centre Léon Bérard (Regional Cancer Center) has implemented a computerized model to manage all different treatment schedules. We developed a software program based on two different steps. Firstly, standard treatment schedules are programmed for each type of disease. To offer a better view of the influence of treatment on daily life, we added information such as place of treatment (ambulatory, inpatient, outpatient) impact on well being (side effects, risk of aplasia...), future evaluations and medical acts (CT scan, MRI, lumbar puncture...) as well as actions the patient should take (blood cell count, to have eaten nothing...). Secondly, it tailors these standard treatments as well as all complementary information's to the specific needs of each patient, based on the medical information available in their computerized records. This personalized plan may be modified and adjusted at any time including therefore more and more real details and insights for each patient (delay of chemotherapy, dates of CT scan....). This would help patients and caregivers to better understand the different phases of the treatment and, thus, improve patient follow-up and information at every step of patient management. This tool is currently being tested at the Centre Léon Bérard.

Metastatic osteosarcoma at diagnosis: prognostic factors and long-term outcome--the French pediatric experience.

BACKGROUND: The objective of this report was to estimate long-term outcome and prognostic factors in children and adolescents who presented with metastatic osteosarcoma at diagnosis. Patients were treated in six French pediatric oncology centers with surgery and multiagent chemotherapy, mainly with high-dose methotrexate. Their medical records were reviewed retrospectively. METHODS: The medical records of patients who were treated for metastatic osteosarcoma from 1987 to 2000 were reviewed. Patients were treated with the chemotherapy regimens recommended for nonmetastatic disease in children (the French Society of Pediatric Oncology OS 87 and OS 94 protocols) or, in a few patients, with other chemotherapy regimens. Surgical excision of the primary tumor and, when possible, of all metastatic sites was performed based on a personalized assessment of each patient's situation. RESULTS: Seventy-eight patients age < 20 years were treated. Forty-six patients (59%) had only 1 metastatic site (35 to the lungs and 11 to bone). Twenty-eight patients (36%) achieved a complete remission after combination chemotherapy and surgery. The event-free survival and overall survival rates at 5 years were 14% and 19%, respectively. To date, 14 patients (18%) have remained alive with a median follow-up of 112 months. Pretreatment features associated with a shorter event-free survival in the multivariate analysis were metastasis to at least two organs and high alkaline phosphatase level. Patients with at least 1 of these poor prognostic factors had a 2.6% event-free survival rate at 5 years despite treatment. CONCLUSIONS: The survival of patients with metastatic osteosarcoma were treated with conventional chemotherapy and surgery remained very poor. Patients should be classified into different prognostic groups and treated accordingly. New therapeutic approaches are warranted to improve the prognosis for patients with the most severe disease.

Persistence of medical change at implementation of clinical guidelines on medical practice: a controlled study in a cancer network.

PURPOSE: A cancer network of general or private hospitals of a French region was started in 1995 for improving quality of care and rationalizing medical prescriptions. The impact of implementing a clinical practice guidelines (CPG) project assessed conformity with guidelines in medical practice; significant changes were observed within the network, whereas no changes were observed in a control region without cancer network. In the present study, we evaluated the persistence of conformity to guidelines through a new medical audit. PATIENTS AND METHODS: In 1999, the hospitals of the previously compared experimental and control groups accepted to reassess the impact of CPG. A controlled transversal study was performed in the experimental group (cancer network) and in the control group (no regional cancer network). In 1996 (first audit) and in 1999 (present audit), all new patients with colon cancer (177 and 200 in experimental group and 118 and 100 in control group, respectively) and early breast cancer (444 and 381 in experimental group and 172 and 204 in control group, respectively) were selected. RESULTS: In the experimental group, the compliance of medical decisions with CPG was significantly higher in 1999 than in 1996 for colon cancer (73%; 95% CI, 67% to 79% v 56%; 95% CI, 49% to 63%, respectively; P = .003) and similar for the two periods for breast cancer (36%; 95% CI, 31% to 41% v 40%; 95% CI, 35% to 44%, respectively; P = .24). In the control group, compliance was significantly higher in 1999 than in 1996 for colon cancer (67%; 95% CI, 58% to 76% v 38%; 95% CI, 29% to 47%, respectively; P < .001) and identical for the two periods for breast cancer (4%; 95% CI, 1% to 7% v 7%; 95% CI, 3% to 11%, respectively; P = .19). CONCLUSION: The CPG program for cancer management produced persistent changes in medical practice in our cancer network in terms of conformity with CPG.

Predictors of high quality clinical practice guidelines: examples in oncology.

OBJECTIVE: Clinical practice guidelines are widely used as effective tools for improving the management of patients with cancer. However, there is increasing concern about variation in guideline quality. In this study we identified predictors for high-quality guidelines in oncology. DESIGN: The quality scores for 32 oncology guidelines from 13 countries were determined by four independent appraisers using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument. MAIN MEASURE: : The contribution to the quality score of six characteristics of guidelines and three of guideline developing organizations was then assessed using analysis of variance and stepwise linear regression analysis. RESULTS: Some guideline and organizational characteristics were shown to be responsible for a large part of the variations in quality scores. The availability of background information was the strongest predictor of quality with an explained variance ranging from 17% ("Applicability") to 67% ("Rigour of development"). High-quality guidelines were more often produced by government-supported organizations and/or within a structured, coordinated programme. The other characteristics (publication year, type of guideline, format, level of care, and scope) were not independent predictors of quality. CONCLUSIONS: Guidelines should provide more explicit information about the context of their development and methods used in order to improve their quality and thus encourage their use in clinical practice.

Factors predicting home death for terminally ill cancer patients receiving hospital-based home care: the Lyon comprehensive cancer center experience.

This study aimed to determine factors favoring home death for cancer patients in a context of coordinated home care. A retrospective study was conducted among patients followed up by the home care coordinating unit of the cancer center of Lyon. The main endpoint was place of death. Univariate analysis included general characteristics (age, gender, rural or urban residence, disease), Karnofsky Index (KI), type of care at referral (chemotherapy, palliative care, or other supportive care), and coordinating medical oncologist (MCO) home visits. Significant factors were used in a logistic regression analysis. Of 250 patients, 90 (36%) had home death. Low KI and MCO home visit were correlated with home death (odds ratio, respectively, 2.1 and 3.1). These results indicate that health care support favors home death. A hospital-based home care unit is effective for bridging the gap between community and hospital. MCO home visits offer concrete support to health care professionals, patients, and relatives.

[Breast cancer screening in France].

From a general review of the literature on breast cancer screening, authors appointed by the parliament office for healthcare policy assessment (Office Parlementaire d'Evaluation des Politiques de Santé, OPEPS) demonstrate that, despite recent controversies, screening is both medically and economically effective. The organisation and specifications of screening are considered. The French situation is examined in the light of European recommendations and compared to other systems in place. After analysing the outcome of screening, particularly the results of the 2003 Cancer Plan, the authors considered the risks of screening, and the type of information given to women.

[Understanding positon emission tomography (PET) with [18F]-FDG in clinical oncology. Informations dedicated to patients and relatives].

In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program (SSP). The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information, developed in this program, is based on clinical practice guidelines produced by the FNCLCC and the twenty French regional cancer centres, the National League against Cancer, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and caregivers. The guidelines, "Standards, Options: Recommendations" (SOR) are used as primary information sources. The handbook SOR SAVOIR PATIENT Understanding positron emission tomography (PET) with [18F]-FDG in clinical oncology, integrally published in this issue of the Bulletin du Cancer, is an adapted version of the clinical practice guidelines (CPG) Standards, Options and Recommendations for positron emission tomography (PET) with [18F]-FDG in clinical oncology. The main objectives of this article are to allow persons affected by cancer and their close relatives to better understand this medical imaging technique and its implementation. This document also offers health professionals a synthetic evidence-based patient information source that should help them communicate that information during the physician-patient encounter. Positron emission tomography (PET) is a scintigraphy technique using a radiotracer, [18F]-fluorodeoxyglucose (abbreviated [18F]-FDG), administered intravenously into the patient's arm. This tracer, similar to glucose (sugar), binds to cancer cells and temporarily emits radiations that can be recorded by a special camera in the PET scanner. PET scanning can be used to obtain complementary information at different stages of the disease, whether for assessing diagnosis, treatment evolution or follow-up. By 2007, in the framework of the government plan against cancer, about seventy-five PET scanners are expected to be installed in France. Twenty-four are currently in use; a similar number is under installation. At the end of this process, all French regions should have at least one PET imaging equipment. The SOR SAVOIR PATIENT guide: Understanding positron emission tomography (PET) with [18F]-FDG in clinical oncology and the integral report of CPG SOR 2003: Standards, Options and Recommendations for positron emission tomography (PET) with [18F]-FDG in clinical oncology can be downloaded from the FNCLCC website: http:\\www.fnclcc.fr.

[Standards and Options for the use of radiation therapy in the management of patients with osteosarcoma. Update 2004].

CONTEXT: The A "Standards, Options and Recommendations A" (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the 20 French regional cancer centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVE: To update the SOR recommendations for the use of radiation therapy in the management of patients with osteosarcoma. This work was performed in collaboration with the French society against cancers in children and adolescent (SFCE). METHODS: Data have been identified by literature search using MedlineA (from January 1992 to October 2003). In addition several Internet sites were searched in October 2003. RESULTS: The 3 mains standards are: 1) local and exclusive curative irradiation is not indicated as primary treatment for osteosarcoma or for local and operable recurrence, except for lesion in inaccessible sites or if the patient refuses surgery; 2) local and prophylactic adjuvant irradiation is not indicated for the treatment of osteosarcoma after chemotherapy (neoadjuvant and/or adjuvant) and complete macro or microscopic surgery, except for nonoperable R1 or R2 surgical resection and 3) whole-lung prophylactic irradiation is not indicated in non-metastatic osteosarcoma. Systemic metabolic radiotherapy for pain treatment, using samarium-153 ethylene diamine tetramethylene phosphonic acid (Sm-153-EDTMP) can be offered to patients with painful metastatic osteosarcoma or in case of recurrent bone sites inaccessible to local therapies (surgery, external irradiation).

Ewing sarcoma: the pediatrician's point of view.

BACKGROUND: Integrated multimodal care is needed for patients with Ewing sarcoma, which is the second most common primary bone malignancy in children and adolescence. Chemotherapy increases survival from less than 5% to 65-70% for patients with localized tumors and to 25-30% for those with metastases at diagnosis. Surgery is a major tool, whereas advances in imaging techniques have improved the indications for and the optimization of treatment. Radiotherapy remains useful, either alone or in addition to surgery, and new techniques (conformational RT and IMRT) will reduce short-term toxic effects. Pediatric oncologists do not outweigh surgeons or radiation therapists, but they are the ones who coordinate the medical team, which also includes pathologists and imaging specialists. METHODS: The point of view of the pediatric oncologist was assessed as follows: the place of chemotherapy in Ewing tumor treatment, the place of radiotherapy in Ewing tumor treatment (including why avoid radiotherapy when technically possible in children), and how to proceed into the future? The place of surgery as local treatment for Ewing tumors was also evaluated. RESULTS: These reviews show a dynamic and kaleidoscopic panorama of intense activity at the laboratory and clinical levels. CONCLUSIONS: Though good survival rates have been achieved, improvements using entirely new approaches are needed.
