RESUMO
OBJECTIVE: To analyze trends in cancer incidence and mortality (France, 1990-2018), with a focus on men-women disparities. METHODS: Incidence data stemmed from cancer registries (FRANCIM) and mortality data from national statistics (CépiDc). Incidence and mortality rates were modelled using bidimensional penalized splines of age and year (at diagnosis and at death, respectively). Trends in age-standardized rates were summarized by the average annual percent changes (AAPC) for all-cancers combined, 19 solid tumors, and 8 subsites. Sex gaps were indicated using male-to-female rate ratios (relative difference) and male-to-female rate differences (absolute difference) in 1990 and 2018, for incidence and mortality, respectively. RESULTS: For all-cancers, the sex gap narrowed over 1990-2018 in incidence (1.6 to 1.2) and mortality (2.3 to 1.7). The largest decreases of the male-to-female incidence rate ratio were for cancers of the lung (9.5 to 2.2), lip - oral cavity - pharynx (10.9 to 3.1), esophagus (12.6 to 4.5) and larynx (17.1 to 7.1). Mixed trends emerged in lung and oesophageal cancers, probably explained by differing risk factors for the two main histological subtypes. Sex incidence gaps narrowed due to increasing trends in men and women for skin melanoma (0.7 to 1, due to initially higher rates in women), cancers of the liver (7.4 to 4.4) and pancreas (2.0 to 1.4). Sex incidence gaps narrowed for colon-rectum (1.7 to 1.4), urinary bladder (6.9 to 6.1) and stomach (2.7 to 2.4) driven by decreasing trends among men. Other cancers showed similar increasing incidence trends in both sexes leading to stable sex gaps: thyroid gland (0.3 to 0.3), kidney (2.2 to 2.4) and central nervous system (1.4 to 1.5). CONCLUSION: In France in 2018, while men still had higher risks of developing or dying from most cancers, the sex gap was narrowing. Efforts should focus on avoiding risk factors (e.g., smoking) and developing etiological studies to understand currently unexplained increasing trends.

Second primary diffuse large B cell lymphoma (spDLBCL) is defined as a metachronous tumor occurring after a first primary cancer. To date, while R-CHOP is the standard first-line treatment for de novo DLBCL, no available data show that R-CHOP is the optimal treatment for spDLBCL. This exploratory study aimed to investigate treatment of spDLBCL. From 2008 to 2015, the Poitou-Charentes general cancer registry recorded 68 cases of spDLBCL ≤ 80 years old, having received a first-line treatment with either R-CHOP (78%) or other regimens (22%). Patients without R-CHOP have worse overall survival in univariate (HR 2.89 [1.33-6.24], P = 0.007) and multivariate (HR 2.98 [1.34-6.67], P = 0.008) analyses. Patients without R-CHOP more frequently had PS > 1 (67% vs. 28%, P = 0.007) and prior chemotherapy (60% vs. 26%, P = 0.02), which suggests that both of these factors influence a clinician's decision to not use R-CHOP. Prior chemotherapy had no prognostic impact in univariate and multivariate analyses; this result could call into question the risk-benefit balance of not using R-CHOP to prevent toxicity. In our study, one DLBCL out of ten occurred after a first primary cancer, and as regards de novo DLBCL, R-CHOP appeared to be the best first-line treatment. Larger series are needed to confirm these results.

Multiple myeloma is a haematological malignancy whose care is spread over several specialities and provided by centres that various sizes, which raises the issue of equal opportunities in care access. Incident cases of myeloma between 2008 and 2010 were exhaustively identified by the Poitou-Charentes Cancer Registry. To ascertain the quality of care, the diagnosis, staging, and treatment administered were compared to international recommendations. Three hundred and sixty-seven patients were included. The diagnostic procedure exhibited 98% compliance, the staging 58%, and treatment 89%. Concerning diagnostic and staging, non-compliance with recommendations was associated to the failure to perform collegiate case assessments in multidisciplinary team (MDT) meetings [OR 2.15 (1.15-4.04)], care provided at a secondary centre, and a distance between home and the centre of 5-25 km [2.16 (1.06-4.40)] and 25-50 km [2.86 (1.37-6.01)]. Regarding treatment, non-compliance with recommendations was associated with care provided at a secondary centre [5.28 (2.03-13.75)]. Finally, diagnosis, staging and treatment quality improved over time. This study underlines the need to improve the organisation of the healthcare offer, so that patients can receive the best possible care. MDT seems to be the main means to improve quality of care.

The current study set out to automatically generate waiting times for access to surgery, chemotherapy and radiotherapy, and to analyse their determinants for non-metastatic breast cancer patients. We used data from the Poitou-Charentes regional cancer registry of women diagnosed with stages I-III breast carcinoma between 2008 and 2010. Waiting times were automatically computed from a previously validated algorithm modelling the care trajectory and then compared with national guidelines. The population of this study included 1082 patients. The compliance with guidelines ranged from 52.4% (access to adjuvant chemotherapy) to 89.2% (access to adjuvant radiotherapy). Younger age, a higher TNM stage, a lower grade, having a triple negative tumour, being the subject of multidisciplinary meetings and being a patient at a public hospital were associated with longer waiting times. The main result was the significant heterogeneity between geographical areas of treatment for all waiting times studied. The original, reproducible use of a registry-based automated algorithm to generate waiting times will help to follow these indicators routinely and efficiently.

OBJECTIVE: The aim of this study was to develop and evaluate a selection algorithm of relevant records for the notification of incident cases of cancer on the basis of the individual data available in a multi-source information system. METHODS: This work was conducted on data for the year 2008 in the general cancer registry of Poitou-Charentes region (France). The selection algorithm hierarchizes information according to its level of relevance for tumoral topography and tumoral morphology independently. The selected data are combined to form composite records. These records are then grouped in respect with the notification rules of the International Agency for Research on Cancer for multiple primary cancers. The evaluation, based on recall, precision and F-measure confronted cases validated manually by the registry's physicians with tumours notified with and without records selection. RESULTS: The analysis involved 12,346 tumours validated among 11,971 individuals. The data used were hospital discharge data (104,474 records), pathology data (21,851 records), healthcare insurance data (7508 records) and cancer care centre's data (686 records). The selection algorithm permitted performances improvement for notification of tumour topography (F-measure 0.926 with vs. 0.857 without selection) and tumour morphology (F-measure 0.805 with vs. 0.750 without selection). CONCLUSION: These results show that selection of information according to its origin is efficient in reducing noise generated by imprecise coding. Further research is needed for solving the semantic problems relating to the integration of heterogeneous data and the use of non-structured information.

OBJECTIVE: Our study aimed to construct and evaluate functions called "classifiers", produced by supervised machine learning techniques, in order to categorize automatically pathology reports using solely their content. METHODS: Patients from the Poitou-Charentes Cancer Registry having at least one pathology report and a single non-metastatic invasive neoplasm were included. A descriptor weighting function accounting for the distribution of terms among targeted classes was developed and compared to classic methods based on inverse document frequencies. The classification was performed with support vector machine (SVM) and Naive Bayes classifiers. Two levels of granularity were tested for both the topographical and the morphological axes of the ICD-O3 code. The ability to correctly attribute a precise ICD-O3 code and the ability to attribute the broad category defined by the International Agency for Research on Cancer (IARC) for the multiple primary cancer registration rules were evaluated using F1-measures. RESULTS: 5121 pathology reports produced by 35 pathologists were selected. The best performance was achieved by our class-weighted descriptor, associated with a SVM classifier. Using this method, the pathology reports were properly classified in the IARC categories with F1-measures of 0.967 for both topography and morphology. The ICD-O3 code attribution had lower performance with a 0.715 F1-measure for topography and 0.854 for morphology. CONCLUSION: These results suggest that free-text pathology reports could be useful as a data source for automated systems in order to identify and notify new cases of cancer. Future work is needed to evaluate the improvement in performance obtained from the use of natural language processing, including the case of multiple tumor description and possible incorporation of other medical documents such as surgical reports.

OBJECTIVES: Development and validation of an epistaxis-specific quality-of-life questionnaire (EQQoL) to evaluate the impact on quality of life of epistaxis, during hereditary hemorrhagic telangiectasia (HHT). STUDY DESIGN: Prospective clinical study using QoL instruments administered twice in HHT patients. PATIENTS AND METHODS: In total, 109 patients who had epistaxis and a clinical diagnosis of HHT according to Curacao criteria were included. Invoice of the questionnaire in 2004 and 2006 included SF-36, Jenkins` sleep scale and the new epistaxis-specific13-item EQQoL. RESULTS: EQQoL uptake rate was 98%, mean score 58/100 +- 27, and Cronbach alpha 0.96. EQQoL was sensitive to change with a strong correlation with the course of epistaxis. Factorial analysis showed that EQQoL was clearly distinct from SF-36 and Jenkins sleep scales. In stepwise multivariate ordinal logistic regression, frequency and duration of epistaxis were both associated with lower EQQoL. Conversely, visceral involvement and comorbidity had independent impact on SF-36 scores, but not on EQQoL. CONCLUSIONS: This new epistaxis-specific EQQoL questionnaire provides complementary information on the impact of HHT on patients quality of life relative to the SF-36 generic questionnaire. After international validation, the EQQoL might prove a useful tool for treatment evaluation.

BACKGROUND: Rotating hinge knee prostheses are indicated in revisions especially when major ligament laxity or substantial AP deformities are present. These situations make ligament balancing difficult with less constrained design implants. Despite its use for nearly 50 years, this type of prosthesis continues to have a poor reputation due to a high complication rate. HYPOTHESIS: Complications are frequent after this type of arthroplasty and the complication rate is similar in primary or revision arthroplasties. The objective of this study is to report the medium-term results of these implants and determine the eventual predictive factors of complications in order to refine operative indications. MATERIAL AND METHODS: In this retrospective study of patients operated on between 1998 and 2006, 85 Endo-Modell (Link) rotating hinge knee prostheses had been used in 61 females and 24 males. The mean age at surgery was 72.4 years (range, 32-92 years). Fifty-two arthroplasties were primary and 33 were revisions either for loosening (24) or deep infections (9). The mean follow-up was 36 months+/-22 (range, 0-75 months). RESULTS: Complications were observed in 24 patients (28.2%): nine deep infections, four patellar complications, and three cases of aseptic loosening. No significant difference was found between the primary arthroplasties and the revisions regarding all complication types. A significant relation was established between the occurrence of a complication and presence of several associated comorbidity factors (obesity, heart disease, diabetes, etc.). DISCUSSION: The use of this type of implant carries a high risk of complications, higher than the one pertaining to unconstrained design prostheses; this fact is noted irrespective of the surgical indication and other comparison elements. The leading criteria to poor functional results appear to be the indication (gonarthrosis with substantial ligament laxity at primary surgery) and the number of associated comorbidities. These prostheses should therefore be restricted to selected indications, notably in view of the fact that less constrained prostheses give superior outcomes. LEVEL OF EVIDENCE: Level IV. Retrospective therapeutic study.

Thoracolumbar fractures are frequent and the functional outcomes are sometimes severe. This multicentric study, including five medical centers, was performed to evaluate the long-term outcomes of the patients. One hundred and thirty six patients with thoracolumbar fracture (T11 to L2) was evaluated with a minimal follow-up of two years. Every one had a clinical exam with a score of Oswestry and an X-Ray study (before and after treatment and at revision). Most of them presented compression fractures, the most often at L1 level. On X-rays, a gain was noted on the vertebral kyphosis immediately after surgery, but there is a loss of correction over time whatever the treatment. The clinical outcomes for the patients were great, with an Oswestry average score of 6,4. A correlation was noted between this functional score and vertebral kyphosis. So, an anterior column strengthening (isolated or performed during the surgery) could improve these functional outcomes. Moreover, the Thoraco Lumbar Injury Severity Score (TLISS) seems to be a simple organigram to determine the most appropriate treatment of these fractures, with particular attention to the distraction mechanism or posterior ligamentous complex lesions. However, RMI before surgery is necessary to evaluate these lesions.

Health care network should promote better quality, equity and care efficacy. On the subject of breast cancer, literature has shown inequality in care depending on geographical areas and health centres locations. This article illustrates a method of analysis of female non in situ non metastatic breast cancer patients hospital care pathway, from the 2002 and 2003 Poitou-Charentes' county Diagnosis Related Groups (DRG's) data bases. The treatments several phases are described along with their combination. The number of chemotherapy and radiotherapy sessions per patient are each analysed for comparison between Health Centres, Health Centres Status, and in view of the referentials recommendations. Several health pathways options are quantified: Mono/pluri Health Centres sites, inside/outside a geographical department, inside/outside Poitou-Charentes county. Nine hundred and nine patients hospital care pathways are described. Surgery was more often partial (66%), with Health Centres variation between 17 and 68%. Among the 308 patients who had chemotherapy, 78% received between 4 and 6 sessions, with variation per Health Centre between 65 and 90%. Radiotherapy is difficult to trace because of the Health Centres non systematic radiotherapy sessions linkage, and private Health Centres lack of information (no DRG's). 91% of identified radiotherapy benefiting patients had 25 to 35 sessions, in conformation with recommendations depending on the surgery performed with Health Centres variation ratio between 76 and 96%. Hospital care pathways options between two type of treatments were identified. 90% of the hospital care pathways took place in the same geographical department, and 30% took place in public Health Centres alone. Despite radiotherapy tractability limits, proper DRG's data collection allows the description of health pathways between Health Centres and allows health practice disparity identification. Using this tool, in accordance with the Cancer Plan, can therefore help health networks in evaluating care pathway in cancer and many other fields.

Better knowledge and understanding of students' health attitudes and behaviours are necessary to more effectively plan targeted prevention strategies. A survey conducted among 617 students at the University Institute of Technology in Poitiers showed that although some indicators affirm good health (relationships with friends and family, appropriate contact with care providers in the health system and regular visits to prevention centres, sexual life, and sports and physical fitness), other indicators reveal a certain amount of suffering among the student population. Students reported suicidal thoughts, symptoms of poor well-being (fatigue, sleeping disorders, concentration problems, sadness or depression) and poor eating habits and/or eating disorders. Consumption of both legal and illegal products seems to be a means utilised to facilitate the social integration process for some students. Therefore, this underlines a significant challenge for prevention campaigns to develop an alternative role model, which promotes the image and profile of a healthy student, with a strong sense of self-esteem, who is well-integrated with his peers without having to engage in substance abuse.

INTRODUCTION: The aim of the study was to establish whether family physicians are influenced by their own smoking habits when issuing prevention messages to patients who smoke. METHODS: 257 Family physicians of the Vienne Department answered a survey (participation rate: 70%) investigating their own smoking habits and how they approach patients who smoke. RESULTS: The prevalence of smoking among respondents was 26%; 30% were ex-smokers and 44% had never smoked. Regular smokers (16%) generally smoked 15 cigarettes a day and 49% were nicotine dependent--15% highly so. When consulting, 44% of doctors stated that they systematically addressed smoking habits and 41% declared that they gave minimal smoking cessation advice. Doctors who smoke were less prone to ask their patients whether they smoke (p = 0.036) and whether they had considered quitting (p = 0.045). Unlike those who didn't smoke or had quit smoking, doctors who smoke often believed that their smoking habits had no impact on their relationship with the patients or that it might even make communication with the patient easier (p < 0.0001). CONCLUSIONS: Family physicians' smoking habits have an impact on their interaction with patients who smoke. This must be taken into account in training sessions for smoking cessation.
