[Development of an artificial intelligence system to improve cancer clinical trial eligibility screening]. Bull Cancer 2024; 111:473-482. [PMID: 38503584 DOI: 10.1016/j.bulcan.2024.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/03/2024] [Accepted: 01/12/2024] [Indexed: 03/21/2024]
Abstract
INTRODUCTION The recruitment step of all clinical trials is time consuming, harsh and generate extra costs. Artificial intelligence tools could improve recruitment in order to shorten inclusion phase. The objective was to assess the performance of an artificial intelligence driven tool (text mining, machine learning, classification…) for the screening and detection of patients, potentially eligible for recruitment in one of the clinical trials open at the "Institut de Cancérologie de Lorraine". METHODS Computerized clinical data during the first medical consultation among patients managed in an anticancer center over the 2019-2023 period were used to study the performances of an artificial intelligence tool (SAS® Viya). Recall, precision and F1-score were used to determine the artificial intelligence algorithm effectiveness. Time saved on screening was determined by the difference between the time taken using the artificial intelligence-assisted method and that taken using the standard method in clinical trial participant screening. RESULTS Out of 9876 patients included in the study, the artificial intelligence algorithm obtained the following scores: precision of 96 %, recall of 94 % and a 0.95 F1-score to detect patients with breast cancer (n=2039) and potentially eligible for inclusion in a clinical trial. The screening of 258 potentially eligible patient's files took 20s per file vs. 5min and 6s with standard method. DISCUSSION This study suggests that artificial intelligence could yield sizable improvements over standard practices in several aspects of the patient screening process, as well as in approaches to feasibility, site selection, and trial selection.

Consore: A Powerful Federated Data Mining Tool Driving a French Research Network to Accelerate Cancer Research. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:189. [PMID: 38397680 PMCID: PMC10887639 DOI: 10.3390/ijerph21020189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 01/28/2024] [Accepted: 01/31/2024] [Indexed: 02/25/2024]
Abstract
BACKGROUND Real-world data (RWD) related to the health status and care of cancer patients reflect the ongoing medical practice, and their analysis yields essential real-world evidence. Advanced information technologies are vital for their collection, qualification, and reuse in research projects. METHODS UNICANCER, the French federation of comprehensive cancer centres, has innovated a unique research network: Consore. This potent federated tool enables the analysis of data from millions of cancer patients across eleven French hospitals. RESULTS Currently operational within eleven French cancer centres, Consore employs natural language processing to structure the therapeutic management data of approximately 1.3 million cancer patients. These data originate from their electronic medical records, encompassing about 65 million medical records. Thanks to the structured data, which are harmonized within a common data model, and its federated search tool, Consore can create patient cohorts based on patient or tumor characteristics, and treatment modalities. This ability to derive larger cohorts is particularly attractive when studying rare cancers. CONCLUSIONS Consore serves as a tremendous data mining instrument that propels French cancer centres into the big data era. With its federated technical architecture and unique shared data model, Consore facilitates compliance with regulations and acceleration of cancer research projects.

Residential proximity to vines and risk of childhood embryonal tumours in France - GEOCAP case-control study, 2006-2013. ENVIRONMENTAL RESEARCH 2024; 240:117417. [PMID: 37865323 DOI: 10.1016/j.envres.2023.117417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 09/29/2023] [Accepted: 10/14/2023] [Indexed: 10/23/2023]
Abstract
BACKGROUND Exposure to pesticides has been suggested as a potential risk factor for childhood embryonal tumour. The existing literature has mainly focused on parental occupational exposure and domestic use of pesticides, and is very limited for residential exposures to agricultural pesticides. The study aimed to test the hypothesis of an increased risk of embryonal tumour in children living close to viticultural plots, likely to be subject to frequent pesticide applications. METHODS The study is part of the French national registry-based GEOCAP program. We included 2761 cases of neuroblastoma, retinoblastoma, Wilms tumour and rhabdomyosarcoma diagnosed before the age of 15 years in the 2006-2013 period, and 40,196 controls representative of the same age population during this period. Indicators of proximity to vines, the presence of vines and viticulture density within 1000 m of the geocoded addresses of residence, were evaluated combining three sources of data on agricultural land use in a geographic information system. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) using unconditional logistic regressions and carried out several sensitivity analyses to test the stability of the results. RESULTS Approximately 10% of the controls lived within 1000 m of vines, with regional variations ranging from <1% to 38%. We observed a 5% increase in the risk of neuroblastoma for a 10% increase in viticulture density (OR = 1.05, 95% CI: 0.98-1.13), with a regional heterogeneity. The indicators of proximity to vines were not associated with the other non-CNS embryonal tumours. CONCLUSION The study showed a slight increase in the risk of neuroblastoma in children living close to vines, suggesting that residential exposure to agricultural pesticides may be involved in the occurrence of these tumours.

Impact of age on survival according to molecular tumor findings in children and adolescents with soft-tissue and bone sarcoma: The BIOSCA project. Cancer Epidemiol 2023:102398. [PMID: 37357067 DOI: 10.1016/j.canep.2023.102398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 06/05/2023] [Accepted: 06/09/2023] [Indexed: 06/27/2023]
Abstract
BACKGROUND Adolescents (15-19 years) with sarcoma are known to have significantly worse survival than children (0-14 years). One possible reason may be that the adolescent sarcomas exhibit specific biological characteristics resulting in differences in clinical presentation and treatment resistance behaviors. The BIOSCA project aims to further explore these age-related differences in survival accounting for molecular tumor characteristic in children and adolescents with sarcoma. METHODS A retrospective national population-based observational study with documented somatic genetic analyses was conducted between 2011 and 2016 of all patients aged from 0 to 17 years with a diagnosis of sarcoma using the National Registry of Childhood Cancers Database. RESULTS A total of 1637 children (0-9years: 40%), preadolescents (10-14years: 35%) and adolescents (15-17 years: 25%) with a diagnosis of bone (N = 845) or soft-tissue (N = 792) sarcoma were included. Adolescents had significantly worse outcome for undifferentiated small round cell sarcoma (USRCS), alveolar rhabdomyosarcoma (ARMS), and epithelioid sarcoma. Five-year overall survivals were worse among CIC-rearranged USRCS cases (47% [95%CI:21-69]) as compared to other USRCS, and PAX3::FOXO1 ARMS patients (44% [95%CI:32-55]) as compared to other ARMS. Adjusting for stage and genomic-profiling status, adolescents with USRCS were 1.6-fold more likely to die than children (P = 0.05), while the difference in survival between age of ARMS patients was weaken. Indeed, the prevalence of PAX3::FOXO1 increased significantly with age. CONCLUSION Age was an independent prognostic factor of outcome only in patients with USRCS, while the association between age and survival of patients with ARMS could be partly explained by differences in prevalence of PAX3::FOXO1.

PAX-FOXO1 fusion status in children and adolescents with alveolar rhabdomyosarcoma: Impact on clinical, pathological, and survival features. Pediatr Blood Cancer 2023; 70:e30228. [PMID: 36722003 DOI: 10.1002/pbc.30228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 01/04/2023] [Accepted: 01/11/2023] [Indexed: 02/02/2023]
Abstract
BACKGROUND Alveolar rhabdomyosarcoma (ARMS) is an aggressive pediatric cancer and cases with fusion PAX3-FOXO1 and PAX7-FOXO1 seem to have a poor prognosis. The aim is to evaluate whether PAX-FOXO1 alterations influence clinical outcome in childhood and adolescence population with ARMS. PROCEDURE A population-based study was conducted between 2011 and 2016 in patients less than 17 years with a diagnosis of ARMS. Overall survival (OS) depending on fusion status with clinical factors was analyzed. RESULTS Out of 111 ARMS patients recorded in the French National Childhood Cancer Registry during the 2011-2016 period, 61% expressed PAX3-FOXO1, 15% expressed PAX7-FOXO1, 13% were FOXO1 fusion-positive without PAX specification, and 7% were PAX-FOXO1 negative (n = 4 missing data). Compared to patients with PAX7-FOXO1 positive ARMS, those with PAX3-FOXO1 positive tumor were significantly older (10-17 years: 57.4% vs. 29.4%), and had more often a metastatic disease (54.4% vs. 23.5%). Poorer 5-year OS for patients with PAX3-FOXO1 and PAX not specified FOXO1-positive tumor were observed (44.0% [32.0-55.4] and 35.7% [13.1-59.4], respectively). After adjustment for stage at diagnosis, patients with positive tumor for PAX3-FOXO1 were 3.6-fold more likely to die than those with positive tumor for PAX7-FOXO1. CONCLUSION At the population level, PAX3-FOXO1 was associated with a significant higher risk of death compared to PAX7-FOXO1-positive and PAX-FOXO1-negative tumors, and could explain poorer 5-year OS observed in adolescence population diagnosed with ARMS. A continuous risk score derived from the combination of clinical parameters with PAX3-FOXO1 fusion status represents a robust approach to improving current risk-adapted therapy for ARMS.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Seasonality of main childhood embryonal tumours and rhabdomyosarcoma, France, 2000-2015. Cancer Med 2023; 12:8789-8803. [PMID: 36726302 PMCID: PMC10134357 DOI: 10.1002/cam4.5624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 12/13/2022] [Accepted: 01/03/2023] [Indexed: 02/03/2023] Open
Abstract
Few studies have investigated the seasonal patterns of embryonal tumours. Based on data from the French National Registry of Childhood Cancers, the present study aimed to investigate seasonal variations in embryonal tumour incidence rates by month of birth and by month of diagnosis. The study included 6635 primary embryonal tumour cases diagnosed before the age of 15 years over the period 2000-2015 in mainland France. Assuming monthly variations in incidence rates were homogeneous over 2000-2015, we used a Poisson regression model to test for overall heterogeneity in standardised incidence ratios (SIRs) by month of birth or diagnosis. The seasonal scan statistic method was used to detect monthly excesses or deficits of embryonal tumour cases over the whole study period. The annual reproducibility of the observed monthly variations was formally tested. An overall heterogeneity in incidence rates by month of birth was observed for rhabdomyosarcoma in boys only. Based on the month of diagnosis, a seasonality was evidenced for unilateral retinoblastoma, with a lower incidence rate in the summer (SIRJul-Aug = 0.68, 95% CI = 0.52-0.87), whilst the incidence rate of rhabdomyosarcoma tended to be lower in August (SIRAug = 0.68, 95% CI = 0.52-0.89). No seasonality was detected for the other embryonal tumour groups by month of birth or month of diagnosis. This study is one of the largest to have investigated the seasonality of childhood embryonal tumours. The study showed a seasonal variation in the incidence rates by month of diagnosis for unilateral retinoblastoma and rhabdomyosarcoma. Our findings are likely to reflect a delay in consultation during the summer months. However, the role of seasonally varying environmental exposures cannot be ruled out.

Management and outcomes of adolescent and young adult sarcoma patients: results from the French nationwide database NETSARC. BMC Cancer 2023; 23:69. [PMID: 36670431 PMCID: PMC9854049 DOI: 10.1186/s12885-023-10556-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Accepted: 01/17/2023] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND The initial management of patients with sarcoma is a critical issue. We used the nationwide French National Cancer Institute-funded prospective sarcoma database NETSARC to report the management and oncologic outcomes in adolescents and young adults (AYAs) patients with sarcoma at the national level. PATIENTS AND METHODS NETSARC database gathers regularly monitored and updated data from patients with sarcoma. NETSARC was queried for patients (15-30 years) with sarcoma diagnosed from 2010 to 2017 for whom tumor resection had been performed. We reported management, locoregional recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival (OS) in AYA treated in French reference sarcoma centers (RSC) and outside RSC (non-RSC) and conducted multivariable survival analyses adjusted for classical prognostic factors. RESULTS Among 3,227 patients aged 15-30 years with sarcoma diagnosed between 2010 and 2017, the study included 2,227 patients with surgery data available, among whom 1,290 AYAs had been operated in RSC, and 937 AYAs in non-RSC. Significant differences in compliance to guidelines were observed including pre-treatment biopsy (RSC: 85.9%; non-RSC 48.1%), pre-treatment imaging (RSC: 86.8%; non-RSC: 56.5%) and R0 margins (RSC 57.6%; non-RSC: 20.2%) (p < 0.001). 3y-OS rates were 81.1% (95%CI 78.3-83.6) in AYA in RSC and 82.7% (95%CI 79.4-85.5) in AYA in non-RSC, respectively. Whereas no significant differences in OS was observed in AYAs treated in RSC and in non-RSC, LRFS and PFS were improved in AYAs treated in RSC compared to AYAs treated in non-RSC (Hazard Ratios (HR): 0.58 and 0.83, respectively). CONCLUSIONS This study highlights the importance for AYA patients with sarcoma to be managed in national sarcoma reference centers involving multidisciplinary medical teams with paediatric and adult oncologists.

Acute skin toxicity of conventional fractionated versus hypofractionated radiotherapy in breast cancer patients receiving regional node irradiation: the real-life prospective multicenter HYPOBREAST cohort. BMC Cancer 2022; 22:1318. [PMID: 36526987 PMCID: PMC9755801 DOI: 10.1186/s12885-022-10402-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 12/05/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Large-scale trials have shown that hypofractionated adjuvant breast radiotherapy was as effective in terms of survival and local control as conventional fractionated radiotherapy, and acute toxicity was reduced with hypofractionated radiotherapy. However, there is a lack of data about the toxicity of breast with regional nodal irradiation (RNI). The aim of this study was to assess the effect of fractionation on radiation-related acute skin toxicity in patients receiving RNI in addition to whole-breast or chest wall irradiation, using real-life data. METHODS We conducted a prospective, multicenter cohort study with systematic computerized data collection integrated into Mosaiq®. Three comprehensive cancer centers used a standardized form to prospectively collect patient characteristics, treatment characteristics and toxicity. RESULTS Between November 2016 and January 2022, 1727 patients were assessed; 1419 (82.2%) and 308 (17.8%) patients respectively received conventional fractionated and hypofractionated radiation therapy. Overall, the incidence of acute grade 2 or higher dermatitis was 28.4% (490 patients). Incidence was lower with hypofractionated than with conventional fractioned radiation therapy (odds ratio (OR) 0.34 [0.29;0.41]). Two prognostic factors were found to increase the risk of acute dermatitis, namely 3D (vs IMRT) and breast irradiation (vs chest wall). CONCLUSION Using real-life data from unselected patients with regional nodal irradiation, our findings confirm the decreased risk of dermatitis previously reported with hypofractionated radiation therapy in clinical trials. Expansion of systematic data collection systems to include additional centers as well as dosimetric data is warranted to further evaluate the short- and long-term effects of fractionation in real life.

Abstract
INTRODUCTION Thyroid cancer is the first cause of endocrine malignancy among children. Over the past decades, an increase in the incidence rates (IR) has been observed around the world. Our study aimed to describe epidemiology, therapeutic management and survival rates of children and adolescents with thyroid cancer in France. METHODS A population-based study was conducted between 2000 and 2018 in children and adolescents less than 17 years with a diagnostic of thyroid cancer. RESULTS A total of 774 thyroid cancers were included: 579 papillary (PTC), 83 follicular (FTC), and 111 medullary carcinomas (MTC). PTC are more frequent in females and in adolescents whereas MTC mainly concerned children, mostly with a familial predisposition. Almost all patients underwent thyroidectomy, completed for most patients with PTC and FTC by radioiodine therapy. Cervical dissection was performed more frequently in patients having PTC and MTC compared to those with FTC. Between 2000 and 2018, thyroid cancers IR in children fluctuated between 1.3 and 3.2 per million, without any significant trend. The median follow-up time was 11.3 years in children, and 5.7 years in adolescents. The 5year-OS was greater than 98.5%. CONCLUSIONS Population-based studies are crucial for better understanding and delineation of best management of rare diseases as thyroid cancers in pediatric and adolescent population. Considering the very favorable survival, a stratification should be proposed between cases at low risk and cases at high risk of relapse, in order to consider a strategy of therapeutic de-escalation in the most favorable cases.

Abstract
BACKGROUND Sarcomas are rare, heterogeneous, ubiquitously localized malignancies with many histologic subtypes and genomic patterns. The survival of patients with sarcoma has rarely been described based on this heterogeneity; therefore, the authors' objective was to estimate survival outcomes in patients who had sarcomas using the 2020 version of the World Health Organization classification of soft tissue and bone tumors. METHODS Patients older than 15 years who had incident sarcoma diagnosed between 2005 and 2010 were extracted from 14 French population-based cancer registries covering 18% of the French metropolitan population. Vital status for each patient was actively followed up to June 30, 2013. Net survival (NS) was estimated using the unbiased Pohar-Perme method. RESULTS Overall, 4202 patients were included. NS declined with increasing age at diagnosis. According to topographic groups, large 5-year NS disparities were observed, ranging from 47% among women with gynecologic sarcomas to 89% among patients with skin sarcomas. Patients with soft tissue, bone, and gastrointestinal sarcomas had 5-year NS rates of 53%, 61%, and 70%, respectively. Similar heterogeneity was observed according to histologic subtypes, with 5-year NS ranging from 19% for patients with angiosarcomas to 96% for patients with dermatofibrosarcomas. Patients with sarcoma who displayed missense mutations had a better 5-year NS (74%); those with MDM2-amplified sarcomas had the worst NS (45%). CONCLUSIONS NS rates in patients with sarcoma are presented here for the first time based on the 2020 World Health Organization classification applied to population-based registry data. Large prognostic heterogeneity was observed based on age, topographic and histologic groups, and genomic alteration profiles, constituting a benchmark for future studies and clinical trials.

Abstract
BACKGROUND The French National Cancer Institute recommends the use of survivorship care plans (SCP) for all cancer survivors. Developing useful SCP's requires understanding of what survivors and their providers need and how SCP's can be implemented in practice. We conducted a study to assess the delivery of SCP comprehensive binders for breast cancer women (BCW) and their general practitioners (GP) in a Cancer center from January 2019. METHODS SCP binders, containing a full range of information on topics related to post-cancer care to survivor-specific information and referrals, were given to BCW during a post-treatment dedicated consultation. Then a letter, containing the treatment summary and 5-year follow-up schedule, was sent to their GPs. Comprehensive binder delivery assessment was carried out using item checkbox, and anonymous open-answered, self-reported questionnaires were sent by email to BCW and their GPs. RESULTS The questionnaire response rates were 81.3% for BCW (n = 109/134) and 48.6% for their GPs (n = 52/107). Most BCW (85%) reported that SCP binders provided useful and comprehensive information. However, some of them (18%) felt abandoned and anonymous during the post-treatment follow-up. Most GPs found SCP letters from our anti-cancer center physicians to be useful for their patients, 38% of them had used this information to assure transition of care with other care providers. In addition, GPs were unanimous to express their feeling that this SCP could improve the long-term surveillance of BCW. There was a high concordance between BCW survivors' and PCP' answers, especially regarding SCPs as a communication bridge between GPs and BCW survivors. Response results concerning use of the binders: to talk about them: 59% for BCW vs. 51% for GPs, and to show them: 35% for BCW vs. 31% for GPs. CONCLUSION The opinions of BCW survivors' and PCP' opinions about the use of SCP's by our Cancer Center seems to be favourable. It is essential to implement and develop SCP's as a key tool in long-term surveillance and support for cancer patient survivors and they are a useful instrument for care providers in communication and transition.

Abstract
Purpose: This study was undertaken to determine cancer survival and describe the spectrum of cancers diagnosed among French adolescent and young adult (AYA) population. Methods: All cases of cancer diagnosed in 15-24 years, recorded by all French population-based registries (18% of the French population), over the 2000-2016 period, were included. Age-standardized incidence rates, conventional annual percentage change (cAPC) of incidence over time, and 5-year overall survival (5yOS) were calculated. Results: We analyzed 2734 cancer diagnoses in adolescents and 4199 in young adults. Overall incidence rates were 231.9/106 in 15-19 year olds and 354.0/106 in 20-24 year olds. The most frequently diagnosed cancers in male AYA were malignant gonadal germ-cell tumors (GCT), Hodgkin lymphoma (HL), and malignant melanoma and were HL, thyroid carcinoma, and malignant melanoma in females. Cancer incidence was stable over time with a cAPC of 0.8% (p = 0.72). For all cancers combined, 5yOS was 86.6% (95% CI: 85.8-87.4), >85% for HL, non-Hodgkin lymphomas (NHL), GCT, thyroid carcinomas, and malignant melanomas, and around 60% and lower for osteosarcomas, Ewing tumors, hepatic carcinomas, and rhabdomyosarcomas. The 5yOS has significantly improved from 2000-2007 to 2008-2015 for all cancers pooled, with a substantial gain of 4% for 15-19 year olds and 3% for 20-24 year olds. Conclusion: Notwithstanding the encouraging results for some cancers, and overall, persistent poorer survivals in AYA were shown compared to children for acute lymphoblastic leukemia, osteosarcoma, Ewing tumor, rhabdomyosarcoma, and malignant hepatic tumors. These disparities require further investigation to identify and address the causes of these inferior outcomes.

Incidence and time trends of sarcoma (2000-2013): results from the French network of cancer registries (FRANCIM). BMC Cancer 2020; 20:190. [PMID: 32138705 PMCID: PMC7059296 DOI: 10.1186/s12885-020-6683-0] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 02/26/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The exhaustive collection of new sarcoma cases and their second histologic review offer a unique opportunity to study their incidence and time trends in France according to the major subtypes. METHODS Data were collected from population-based cancer registries covering 22% of the French population. Crude and world age-standardized incidence rates (ASR) were estimated according to anatomic, histological and genetic groups, age and sex over the 2010-2013 period. RESULTS Time trends in incidence were calculated by the annual percent change over the 2000-2013 period. During the most recent period (2010-2013), 3942 patients with sarcoma were included. The ASR of soft-tissue and bone sarcomas, and gastro-intestinal stromal tumors (GIST) were 2.1, 1.0 and 0.6, respectively. For the four most frequent histological subtypes (unclassified, leiomyosarcoma, GIST and liposarcoma), the ASR ranged from 0.4 to 0.7. ASRs were 1.9 for complex genomic and 1.3 for recurrent translocation sarcomas. The time-trend analysis showed a significant increase of sarcoma incidence rate between 2000 and 2005, which stabilized thereafter. Incidence rates increased for four histological subtypes (GIST, chondrosarcoma, myxofibrosarcoma, solitary fibrous tumors) and decreased for three (leiomyosarcomas, Kaposi sarcoma and fibrosarcoma). CONCLUSION To our knowledge, this study is the first to investigate sarcoma incidence based on a systematic pathological review of these cancers and on the updated sarcoma classifications. Due to the paucity of literature on sarcomas, future studies using data from population-based cancer registries should consider a standardized inclusion criterion presented in our study to better describe and compare data between countries.

Abstract
INTRODUCTION Breast cancer of young women has medico-psychological issues, particularly in the perspective of "after cancer" period. The objective of the study was to analyze the changes in management, in a decade including the publication of Cancer Plans I and II. METHODS This retrospective unicentric study involved two populations of women aged 40 and treated at the "Institut de cancérologie de Lorraine" in 2002-2004 (P1) and 2012-2014 (P2). Epidemiological-demographic, histological, diagnostic and therapeutic sequences were analyzed. RESULTS 216 patients were included. The mean age was 35.7 years (range 22-40), with no significant epidemiological difference, except for an increased rate of obesity in P2. Preoperative biopsies became almost systematic and the pre-therapeutic care plan rate increased over the decade from 3.8% to 8% (p < 0.001). The rate of breast-conserving treatment remained stable. The sentinel lymph node rate increased from 4.4% in P1 to 31.9% in P2 (p < 0.001), while the rate of lymph node dissection decreased (p < 0.001) between the two periods. Resort to breast nurses, psycho-oncologists, fertility experts and oncogenetic consultations has also increased. CONCLUSION There is an improvement in the care and management of young women under 40 because of the first Cancer Plans. A study about the impact on the prognosis and a reflection to improve the experience of illness for these women are to lead.

Self-compression Technique vs Standard Compression in Mammography: A Randomized Clinical Trial. JAMA Intern Med 2019; 179:407-414. [PMID: 30715083 PMCID: PMC6440229 DOI: 10.1001/jamainternmed.2018.7169] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Accepted: 10/01/2018] [Indexed: 11/14/2022]
Abstract
Importance Many women dread undergoing mammography, and some may not attend or reattend breast cancer screening because of the discomfort or pain induced by breast compression. Objective To evaluate the noninferiority of the self-compression mammography technique for reducing breast thickness compared with standard compression. Design, Setting, and Participants This prospective, parallel-group, noninferiority randomized clinical trial was conducted from May 7, 2013, to October 26, 2015, at 6 cancer care centers in France. Participants were women aged 50 to 75 years, without a history of recent breast surgical procedure or treatment, and who could perform self-compression. Analyses were performed on intention-to-treat basis from January 27, 2017, to March 30, 2018. Interventions Patients were randomized 1:1 to the self-compression group or the standard compression group. Main Outcomes and Measures Primary end point was breast thickness expressed as the mean of 4 views: right and left craniocaudal and right and left mediolateral oblique. The predefined noninferiority margin was a difference of 3 mm, with a 1-sided 95% CI. Secondary end points included compression force, image quality, requirement for additional views, pain, and patient satisfaction and radiographer assessment questionnaires. Results Among the 549 women randomized, 548 (97.3%) completed the trial. Of these, 275 (48.8%) (mean [SD] age, 61.35 [6.34] years) were randomized to the self-compression arm and 273 (48.5%) (mean [SD] age, 60.84 [6.41] years) to the standard compression arm. The difference in the mean thickness between the 2 arms was lower than the noninferiority margin, with an upper 1-sided 95% CI less than 3 mm (-0.17; 95% CI,-∞ to 1.89 mm; P < .05). Compression force was higher in the self-compression group compared with the standard compression arm for the 4 mammographic views. Pain was statistically significantly lower in the self-compression group (n = 274) compared with the standard compression group (n = 269) (median [interquartile range (IQR)] score, 2 [1-5] vs 3 [1-5]; P = .009). No difference was reported in the image quality scores of the 2 groups or in the number of additional views performed (median [IQR] extra views, 2 [2-2] vs 2 [2-3] extra views; P = .64), whatever the indication, including insufficient image quality (29 [16.8%] vs 27 [15.0%] insufficient quality views; P = .65). No adverse effects or pain were reported by the participants after the self-compression mammography. Conclusions and Relevance Self-compression does not appear to be inferior to standard compression mammography in achieving minimal breast thickness without increasing pain or compromising image quality; this technique may be an effective option for women who want to be involved in their breast examination. Trial Registration ClinicalTrials.gov identifier: NCT02866591.

Adolescent and young adult oncology patients in France: Heterogeneity in pathways of care. Pediatr Blood Cancer 2018; 65:e27235.

Abstract
BACKGROUND In order to evaluate at the population level the impact of the actions developed in France since 2004 to organize the care of adolescents and young adults (AYAs) with cancer, we conducted the present study to provide an unbiased view of the pathway of care of these patients. METHODS Using a population-based registry, we conducted a review of all cases of cancer diagnosed during 2012 and 2013 in 15- to 24-year-old patients living in nineteen French administrative areas. RESULTS The median times for diagnosis and treatment of the 993 included AYAs were 9 weeks (3-22) and 1 day (0-20), respectively. Delays in diagnosis were significantly longer in young adults than in adolescents, especially for soft-tissue sarcomas (48.7 weeks vs. 15.4 weeks, P = 0.04) and bone tumors (21.4 weeks vs. 10.1 weeks, P = 0.04). The first physicians seen by patients were mostly general practitioners (67.4%). Most patients (77.5%) were treated in adult units. Management decisions were taken within the context of a multidisciplinary team (MDT) in 85.3% of cases. MDT meetings that involved both pediatric and adult oncologists were uncommon (15.7% of patients). Twenty-six percent of patients were included in randomized or nonrandomized clinical studies. The proportion of inclusion was significantly higher in adolescents (39.5%) than in young adults (16.8%). CONCLUSION In France, pathways of care for AYAs are heterogeneous. It is necessary to organize a national network of expert centers with adequate medical skills and specific psychosocial support and facilities to provide the best possible care for these patients.

Survival of adolescents with cancer treated at pediatric versus adult oncology treatment centers in France. Pediatr Blood Cancer 2017; 64.

Abstract
BACKGROUND In France, although children aged less than 15 years with cancer are usually referred to pediatric oncology centers, adolescents may be treated at pediatric or adult oncology centers. The objective was to compare survival according to their site of treatment. PROCEDURE Using population-based registration, 15- to 19-year-old patients diagnosed with cancer in 2006 or 2007 and living in six French regions (accounting for 41% of the French population) were included. RESULTS Of the 594 patients included, 33% of the French adolescents were treated at a pediatric oncology center. Compared with those treated at a pediatric center, adolescents treated at an adult center were older, were more likely to have carcinoma and germ-cell tumor, had a longer time to diagnosis, and were less likely to be enrolled in a clinical trial. In addition, the decisions for their management were less likely to be taken in the context of multidisciplinary team meetings. In multivariate analysis, adolescent patients treated at a pediatric center did not have significantly different overall survival (OS) compared with those treated at an adult center (5-year OS: 84.1% [95% confidence interval: 78.6-90.0] versus 87.7% [95% confidence interval: 84.2-91.3]; P = 0.25). CONCLUSIONS The outcomes of French adolescents with cancer have begun to improve, with 81.2% survival in 2006-2007, with no difference between the types of treatment center. However, for this unique group of diseases, survival is not the unique endpoint. In order to ensure good quality of life after cancer, management of those patients requires specific approaches, designed to reduce the late effects of cancer treatment and improve supportive care.

Abstract
In adolescents and young adults (AYA), cancers are rare but represent the third significant cause of death. The aim of this paper was to investigate epidemiological data and pathways of care of AYA in France. During the 2000-2008 period, overall age-standardized incidence rates (ASR) were 254.1/106 in 15-24-year-olds. The most frequently diagnosed cancers in male AYA were malignant gonadal germ-cell tumors and Hodgkin's lymphoma, and were melanoma, thyroid carcinoma and Hodgkin's disease in females. The ASR appeared stable over time. During the 2000-2004 period, the 5-year overall survival for all cancers was 81.8%, with differences between genders and age groups: 78.8% for males and 85.2% for females; 78.5% in 15-19-year-olds and 84.3% in 20-24-year-olds. Survival has significantly improved over time. During the 2006-2007 period, the pathways of care for French adolescent patients with cancer were heterogeneous: 82% were treated in an adult environment, 27% were included in clinical studies, and in 54% of cases the management decisions were taken in the context of a multidisciplinary team. Studies looking at management of AYA with cancer have shown a wide disparity and a lack of collaboration between adult oncologists and pediatric oncologist. An AYA cancer multidisciplinary interest group has been created to determine priorities and coordinate efforts to improve AYA cancer services and care.

Abstract
BACKGROUND Solid tumors are uncommon in the neonatal period but represent an important cause of mortality and morbidity. PROCEDURE Using the French National Registry of Childhood Solid Tumors database, all children, from birth to 28 days of age inclusive, with a primary malignant solid tumor diagnosed between 2000 and 2009 in mainland France were identified. Tumors were classified according to the third version of the International Classification of Childhood Cancer. RESULTS Of total 285 solid tumors over 10 years, the most common cancer was neuroblastoma (47%), followed by germ cell tumors (29%), central nervous system tumors (10%), and soft tissue sarcomas (8%). The annual incidence was 36.6 per million live births. No statistically significant change in time trends of incidence was observed during 2000-2009. Routine ultrasonography during pregnancy established the diagnosis in 52% of cases. Thirteen neonates (4.5%) had congenital abnormalities associated with their tumors. For all solid tumors combined, overall survival was 84.2% (95% CI, 79.4-87.9) at 1 year and 83.8% (95% CI, 79.0-87.6) at 5 years. More favorable prognosis was significantly associated with neonates treated by surgery (65% of cases) compared to those without tumor excision. However, perioperative and postoperative mortality was 8%. CONCLUSIONS Because of their relative rarity, there is a paucity of objective information on the epidemiology, optimal treatment, and long-term outcome of neonatal solid tumors. But to obtain a clearer picture of the epidemiology of neonatal tumors, it is essential to have some recommendations on the methodological approach used to study them.

Survival of European adolescents and young adults diagnosed with cancer in 2000-07: population-based data from EUROCARE-5. Lancet Oncol 2016; 17:896-906. [PMID: 27237614 DOI: 10.1016/s1470-2045(16)00162-5] [Citation(s) in RCA: 178] [Impact Index Per Article: 22.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2015] [Revised: 03/03/2016] [Accepted: 03/03/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND Data from EUROCARE have consistently shown lower survival for adolescents and young adults (AYAs; aged 15-24 years) than for children (0-14 years) for most cancers that affect both groups, and modest survival improvements up to 2000-02. AYAs have longer survival than that of adults for most cancers. We used the latest definition of AYAs (aged 15-39 years) and provided estimates of 5-year relative survival for European AYAs with cancer diagnosed in 2000-07, compared with children and adults (40-69 years) with cancer, and assessed survival improvements over time. METHODS We analysed data from population-based cancer registries of 27 European countries participating in EUROCARE-5. We used the so-called complete method to estimate 5-year, population-weighted relative survival for 19 cancers affecting AYAs and children, and for 27 cancers affecting AYAs and adults. We assessed relative-survival differences between children versus AYAs, and between AYAs versus adults, using the Z test. We used the period approach to estimate 5-year relative survival over time for children and AYAs, and used a generalised linear model to model survival time trends (1999-2007) and to assess the significance of changes over time. FINDINGS We analysed 56 505 cancer diagnoses in children, 312 483 in AYAs, and 3 567 383 in adults. For all cancers combined, survival improved over time for AYAs (from 79% [95% CI 78·1-80·5] in 1999-2002 to 82% [81·1-83·3] in 2005-07; p<0·0001) and children (from 76% [74·7-77·1] to 79% [77·2-79·4]; p<0·0001). Survival improved significantly in children and AYAs for acute lymphoid leukaemia (p<0·0001) and non-Hodgkin lymphoma (p<0·0001 in AYAs and p=0·023 in children). Survival improved significantly in AYAs only for CNS tumours (p=0·0046), astrocytomas (p=0·040), and malignant melanomas (p<0·0001). Survival remained significantly worse in AYAs than in children for eight important cancers: acute lymphoid leukaemias, acute myeloid leukaemias, Hodgkin's lymphomas, non-Hodgkin lymphomas, astrocytomas, Ewing's sarcomas, and rhabdomyosarcomas (p<0·0001 in all cases), and osteosarcomas (p=0·011). INTERPRETATION Notwithstanding the encouraging results for some cancers, and overall, we showed poorer survival in AYAs than in children for the eight important cancers. Recent European initiatives to improve outcomes in AYAs might reduce the survival gap between children and AYAs, but this reduction can only be verified by future population-based studies.

Abstract
BACKGROUND Central nervous system (CNS) tumors are the second most common childhood malignancy. The French National Registry of Childhood Solid Tumors (NRCST) makes it possible to describe this variety of distinct tumor types and to provide incidence and survival data in France on a nationwide basis. METHODS All children aged 0-14 years, who were registered with a primary CNS tumor in the NRCST of France between 2000 and 2008, were identified. Tumors were classified according to the International Classification of Childhood Cancer, third edition. RESULTS Approximately 57% of pediatric CNS tumors were gliomas, with astrocytomas of the pilocytic type predominating. Distributions of subtypes by age showed that primitive neuroectodermal tumors and ependymomas mainly occurred in children aged <5 years. The mean annual incidence rate of CNS tumors was 39 per million. No statistically significant change in time trends of incidence rate was observed during 2000-2008. For all tumors combined, overall survival was 84.8% (95% CI, 83.7%-85.9%) at 1 year and 72.9% (95% CI, 71.5%-74.3%) at 5 years. Survival time trends were studied in a multivariate analysis observing a reduction in the risk of death in periods of diagnosis 2003-2005 (HR = 0.8; 95% CI, 0.7–0.9) and 2006-2008 (HR = 0.7; 95% CI, 0.6-0.9) compared with 2000-2002. CONCLUSIONS The stable incidence rates during the last 10 years could indicate that major changes in environmental risk factors are unlikely, but the ongoing need for population-based surveillance remains relevant. Results indicate a positive trend in the survival probability still persistent in the 2000s.

Abstract
This study aimed to describe cancer incidence (2000-2008) and survival (2000-2004) in France in adolescents and young adults (AYA). All cases of cancer diagnosed in 15-24 years, recorded by all French population-based registries (14% of the French population), over the 2000-2008 period, were included. Incidence change over time was described with the conventional annual percentage change (cAPC). The survival of cases diagnosed (2000-2004) was estimated using Kaplan-Meier method. A total of 1022 in adolescents and 1396 in young adults were diagnosed. Overall incidence rates were 219.4/10(6) in 15-19 year olds and 293.1/10(6) in 20-24 year olds. The most frequently diagnosed cancers in male AYA were malignant gonadal germ-cell tumors and Hodgkin's disease, and were melanoma, thyroid carcinoma, and Hodgkin's disease in females. The age-standardized rates appeared stable over time in AYA, with a cAPC of +2.0% (P = 0.68). The 5-year overall survival for all cancers was different between genders and age groups, with 78.8% (95%CI: 75.6-82.0) for males and 85.2% (95%CI: 82.2-88.1) for females (P = 0.01), and 78.5% (95%CI: 75.0-82.1) in 15-19 year olds and 84.3% (95% CI: 81.6-87.0) in 20-24 year olds (P = 0.02). Noteworthy, the frequency and the distribution of tumor types in AYA are unique and different from the observed at any other age group. Survival in French AYA has improved over time. Epidemiological data might reflect major trends in the risk factors and preventive interventions. Thus, further research into etiology of cancers affecting AYA should become key priorities for cancer control among AYA.

Abstract
BACKGROUND In France, as in other countries, there is a need for a population-based view of access to care and modalities of treatment for adolescents with cancer. PROCEDURE Using a population-based registration, we report pathways of care for 15-19-year-old patients, diagnosed with cancer in 2006 and 2007, living in six French regions, accounting for 41% of the French population. RESULTS The median times (inter-quartile range) for diagnosis and treatment of the 594 included adolescents were 8 weeks (3-17) and 3 days (0-16), respectively. First physicians met by the patients were mostly general practitioners (59%). Seventeen percent of patients were firstly seen on emergency wards. Most of the patients (82%) were treated in an adult environment. Management decisions were taken within the context of a multi-disciplinary team (MDT) in 54% of cases. Twenty-seven percent of patients were included in randomized or non-randomized clinical studies: percentage depended on the tumor type and on the number of on-going trials at the study period. Fifteen percent of patients were included in pediatric studies, 7% in adult studies, and 5% in studies including both adults and children. CONCLUSIONS The pathways of care for French adolescent patients with cancer are heterogeneous. Our results reveal differences in MDT meetings according to tumor types and a lack of effective collaboration between pediatric and adult wards. Efforts must be made to develop cancer networks to ensure that adolescents receive the optimal care in a suitable environment.

Management of patients with head and neck tumours presenting at diagnosis with a synchronous second cancer at another anatomic site. Clin Oncol (R Coll Radiol) 2010; 23:174-81. [PMID: 21130631 DOI: 10.1016/j.clon.2010.10.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2010] [Revised: 10/18/2010] [Accepted: 10/19/2010] [Indexed: 12/22/2022]
Abstract
AIMS To understand management strategies and outcomes of patients diagnosed with a head and neck tumour and a synchronous second cancer developed at another anatomic site. MATERIALS AND METHODS Retrospective analysis of all patients diagnosed with a head and neck carcinoma and a synchronous cancer and engaged in curative-intent treatments. To evaluate therapeutic strategies, each patient's treatment process was divided into sequential therapeutic modalities and corresponding targets (head and neck and/or synchronous tumour) were identified. Patient outcome was analysed with an intent-to-treat approach. RESULTS Forty-three patients were entered into the study (mean age=57.4 years). Synchronous tumours concerned the lung (57.8%), oesophagus (31.1%) or other sites (11.1%). Treatments were complex, including one to four consecutive modalities, with a mean duration of 4.6 months. When both tumours were advanced, treatments were frequently initiated with dual-spectrum chemotherapy (66.7%). In other situations, a locoregional treatment was often (81.1%) proposed immediately. When both tumours were in early stages, this initial locoregional treatment could be extended to target both tumours together (30.0%). For patients whose tumours differed in severity, this locoregional treatment targeted only one tumour (85%); priority was given to the most advanced one (76.5%). Nine patients had definitive treatment interruption. Associated risk factors were a low body mass index (P=0.03) and advanced-stage tumours (P=0.01). Thirty-one patients died (72.1%) with a median time to death of 7.7 months. The median follow-up for survivors was 46.2 months. Three-year overall survival was 33.9%. Low body mass index (P=0.001), advanced-stage synchronous tumours (P=0.03) and oesophageal primaries (P=0.03) altered the overall survival. Three-year locoregional and metastatic progression-free survival was 40.8 and 62.5%, respectively. Low body mass index (P=0.01) and advanced-stage synchronous tumours (P=0.01) increased the risk of disease failure. CONCLUSIONS Head and neck tumours diagnosed with a synchronous cancer are a complex challenge. Despite a severe prognosis, patients who are not underweight, presenting with lower-stage tumours (especially the synchronous tumour) and without oesophageal involvement could most benefit from aggressive treatments.

Abstract
This study analyses survival in 40,392 children (age 0-14 years) and 30,187 adolescents/young adults (age 15-24 years) diagnosed with cancer between 1995 and 2002. The cases were from 83 European population-based cancer registries in 23 countries participating in EUROCARE-4. Five-year survival in countries and in regional groupings of countries was compared for all cancers combined and for major cancers. Survival for 15 rare cancers in children was also analysed. Five-year survival for all cancers combined was 81% in children and 87% in adolescents/young adults. Between-country survival differences narrowed for both children and adolescents/young adults. Relative risk of death reduced significantly, by 8% in children and by 13% in adolescents/young adults, from 1995-1999 to 2000-2002. Survival improved significantly over time for acute lymphoid leukaemia and primitive neuroectodermal tumours in children and for non-Hodgkin lymphoma in adolescents/young adults. Cancer survival in patients <25 years is poorly documented in Eastern European countries. Complete cancer registration should be a priority for these countries as an essential part of a policy for effective cancer control in Europe.

Men with breast cancer have same disease-specific and event-free survival as women. Ann Surg Oncol 2009; 16:972-8. [PMID: 19184227 DOI: 10.1245/s10434-009-0327-6] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2008] [Revised: 12/29/2008] [Accepted: 12/29/2008] [Indexed: 11/18/2022]
Abstract
BACKGROUND Breast carcinoma in men is an uncommon disease. The aim of this study is to compare overall survival (OS) and disease-specific survival (DSS) in a group of matched men and women with breast cancer. METHODS Each man with breast cancer recorded in the database was matched with two women. Matching was done based on age, year of diagnosis, and stage. To compare breast cancer characteristics between men and women, the chi-square test was used for qualitative data and the t-test for quantitative data. Overall survival and DSS were calculated using Kaplan-Meier methods. Cox proportional hazards models have been used to compare survival rates between men and women. RESULTS The 58 male breast cancer patients were matched with 116 female patients. The mean age at diagnosis was 63.9 +/- 11.9 years for men and 65.7 +/- 11.5 years for women (P = .72). The median follow-up was 9.7 years for men and 10.7 years for women. The 5- and 10-year OS for men were, respectively, 58.9% and 33.9%. The 5- and 10-year OS for women were 68.2% and 52.1%. Men with breast cancer had a significant risk of dying compared with women (hazard ratio [HR] = 1.59; 95% confidence interval (95% CI), 1.04-2.42, P = .03). The 5- and 10-year DSS were 73.0% and 55.1% for men, and 72.8 and 61.2% for women, respectively. There was no difference in DSS between the two matched groups (HR = 1.26; 95% CI, 0.76-2.10, P = .37). CONCLUSIONS The prognosis for men with breast carcinoma is similar to that for women with similar-stage disease.

Survival from adolescent cancer. Cancer Treat Rev 2007; 33:609-15.

Abstract
BACKGROUND Adolescent cancer is the leading cause of non-accidental mortality in young people. The tumour types occurring most commonly in this age group are distinctive and differ markedly from those developing in younger children and older adults. OBJECTIVE The aim is to present survival data for the major types of cancer and for all malignancies combined in adolescents aged from 15 to 19 years, highlighting intercountry differences, temporal trends, and age/treatment regimen comparisons of survival rates. RESULTS Results from European and American data show that 5-year overall survival among adolescents with cancer is approximately 73-78%, close to that observed among children. As in paediatric series, there are geographical differences, with lower survival rates in Eastern European countries. Adolescents have substantially lower survival than children for acute lymphoid leukaemia, malignant non-Hodgkin lymphoma, Ewing's tumour, osteosarcoma, soft-tissue sarcoma. Temporal improvement in survival from children cancer is twice higher than survival from adolescents malignancies. CONCLUSION Several reasons could explain these geographical differences, such as better referral, greater availability of complex and expensive treatment regimens, reflecting variations in health care systems and resources. Age-group variations could be explained by differences in biology and in treatment regimen, and lack of participation in clinical trials. Some are inherent in the psychosocial characteristics of these patients, such as delays in seeking medical attention, poor compliance with treatment. It is necessary to focus on cancer in adolescence, as the new frontier in oncology, and adolescents with cancer must be now the subject of specific survival analyses.

Abstract
BACKGROUND To evaluate the efficacy of BCNU, cisplatin, and vincristine (BCV regimen) in a prospective nonrandomized study among newly diagnosed children with high-grade glioma. PROCEDURE Following surgery, patients received a combination of BCNU + cisplatin + VP16 (BCV), over 3 consecutive days. Patients with residual tumor continued this regimen unless no further improvement was observed on MRI, for a maximum of six courses. Patients who underwent complete surgical resection received six courses of adjuvant BCV. RESULTS Seventy-three patients were enrolled. Out of 66 eligible patients with central pathology review, the diagnosis of high-grade glioma was confirmed in 53 cases. The response rate was 20%. With a median follow-up of 128 months, 5- and 10-year event free survival rates are 16 +/- 9 and 13.3 +/- 9.4%. In univariate analysis, two prognostic factors were statistically significant: extent of resection and tumor location, while macroscopic total resection was the only significant prognostic factor in the multivariate analysis. The response to BCV did not translate into improved event free survival. Interstitial pneumonitis occurred in seven patients, leading to six deaths. CONCLUSION This BCV regimen could not be recommended in the treatment of high-grade gliomas in children, according to its lack of efficacy and its unacceptable pulmonary toxicity.

Abstract
Malignancies are rare young French adults but represent the third significant cause of death in the cohort of 15-24 years of age. The aim of this study was to investigate incidence and survival rates of French adolescents and young adults with cancer. All cases of cancer occuring over a 20-year period (1978-1997) in the cohort of patients aged 15 to 24, were obtained from nine population-based registries (10 % of the French population). Basal cell carcinomas of the skin were excluded. 1161 and 1884 cases were recorded in adolescents and young adults, respectively. Overall incidence rates (IR) were 161.4/10(6) in adolescents aged 15-19 years (M/F ratio = 1.3), and 252.6/10(6) in young adults aged 20-24 years (M/F ratio : 1.2). During the 1978-97 period, the IRs appeared stable over the years, +0.4 % [CI95 % = -2.3 ; +3.1] (p = 0.79) for adolescents and +1.7 % [CI95 % = -4.0 ; +7.3] (p = 0.57) for young adults. Five-year overall survival rates were 69.1 % [CI95 % = 66.4-71.8] for adolescents and 74.5 % [CI95 % = 72.3-76.7] for young adults. The 5-year survival rate for patients 15-24 years improved from 62.0 % (CI95 % = 57.5-66.5) in 1978-82 to 80.2 % (IC95 % = 77.7-82.8) in 1993-97. Noteworthy, results in adolescents and young adults are poor compared to the ones from their younger counterparts, especially in patients with acute lymphoblastic leukemia, non-Hodgkin lymphoma, Ewing's sarcoma, osteosarcoma, rhabdomyosarcoma, and astrocytoma. Further studies are warranted to elucidate whether these differences are due to intrinsic biological properties of the tumor or to differences in clinical practices in the two populations.

Impact of intensity-modulated radiotherapy on health-related quality of life for head and neck cancer patients: matched-pair comparison with conventional radiotherapy. Int J Radiat Oncol Biol Phys 2007; 67:1309-17.

Abstract
PURPOSE To assess the benefit of intensity-modulated radiotherapy (IMRT) compared with conventional RT for the quality of life (QOL) of head and neck cancer survivors. METHODS AND MATERIALS Cross-sectional QOL measures (European Organization for Research and Treatment of Cancer QOL questionnaire C30 and head and neck cancer module) were used with a French multicenter cohort of patients cured of head and neck cancer (follow-up > or = 1 year) who had received bilateral neck RT (> or = 45 Gy) as a part of their initial treatment. We compared the QOL mean scores regarding RT modality (conventional RT vs. IMRT). The patients of the two groups were matched (one to one) according to the delay between the end of RT and the timing of the QOL evaluation and the T stage. Each QOL item was divided into two relevant levels of severity: "not severe" (responses, "not at all" and "a little") vs. "severe" (responses "quite a bit" and "very much"). The association between the type of RT and the prevalence of severe symptoms was approximated, through multivariate analysis using the prevalence odds ratio. RESULTS Two comparable groups (67 pairs) were available. Better scores were observed on the head and neck cancer module QOL questionnaire for the IMRT group, especially for dry mouth and sticky saliva (p < 0.0001). Severe symptoms were more frequent with conventional RT concerning saliva modifications and oral discomfort. The adjusted prevalence odds ratios were 3.17 (p = 0.04) for dry mouth, 3.16 (p = 0.02) for sticky saliva, 3.58 (p = 0.02) for pain in the mouth, 3.35 (p = 0.04) for pain in the jaw, 2.60 (p = 0.02) for difficulties opening the mouth, 2.76 (p = 0.02) for difficulties with swallowing, and 2.68 (p = 0.03) for trouble with eating. CONCLUSION The QOL assessment of head and neck cancer survivors demonstrated the benefit of IMRT, particularly in the areas of salivary dysfunction and oral discomfort.

Cancer adolescent pathway in France between 1988 and 1997. Eur J Oncol Nurs 2007; 11:74-81.

Abstract
We report an adolescent cancer pathway from referral, through diagnosis and treatment, to follow-up in France. All cases of cancer among 15-19 years, diagnosed from 1988 to 1997, recorded by nine French population-based cancer registries (10% of French population) were included. The management of adolescent cancer by paediatricians was rare. An adolescents' pathway through cancer care can be summarized as first visit to general practitioner, referral to adult oncologist for haematological malignancy and medical or surgical specialists for solid tumours, treatment in adult unit, and follow-up by adult oncologist, adult medical or surgical specialist, or general practitioner. Only 9% of the 15-19 years are entered into a clinical trial (respectively 6% and 3% into adult and paediatric clinical trial). The inclusion rate changes according to the diagnosis, higher for acute lymphoblastic leukaemia (39%), non-Hodgkin's lymphomas (NHL) (27%), and acute non-lymphoblastic leukaemia (20%). Only 4% of adolescent cancers were managed on shared adult/paediatric departments, especially for soft-tissue sarcomas (14.9%), malignant bone tumours (13.4), central nervous system tumours (6.2%), and NHL (4.4%). Whatever the reasons for lack of participation in clinical trials, an ideal model requiring communication and cooperation between all adult and paediatric specialists involved in adolescent cancer treatment should reduce the large gap in access to cooperative groups.
