RESUMEN

BACKGROUND AND PURPOSE: The association between smoking and acute radiation toxicities of head and neck cancer (HNC) is currently unproven. The aim of the study was to compare the occurrence of acute severe toxicity between active and non-active smokers treated for HNC by radiotherapy. MATERIALS AND METHODS: A prospective monocentric cohort study included patients treated by (chemo)radiotherapy for HNC from January 2021 to January 2023. Smoking status was recorded. Patients underwent a medical exam weekly during the radiotherapy to report acute toxicities according to the Common Terminology Criteria for Adverse Effects system version 5.0. Primary endpoint was the occurrence of at least one grade ≥ 3 acute toxicity among mucositis, dysphagia and dermatitis. RESULTS: Among the 102 patients included, 27.4 % were active smokers, 58.8 % were former smokers and 13.7 % had never smoked. Regarding toxicity, 23.5 % (n = 24) patients experienced severe mucositis, 37.2 % (n = 38) severe dysphagia, 13.7 % (n = 14) severe dermatitis and 54.9 % (n = 56) experienced at least one of them. Occurrence of severe acute toxicity was not statistically associated with smoking during radiotherapy (64.3 % among active smokers versus 51.3 % among non-active smokers; p = 0.24). On multivariate analysis, concurrent chemotherapy (87.5 % vs 65.2 %; OR = 5.04 [1.64-15.52]; p = 0.004) and 2.12 Gy versus 2 Gy fractionation schedule (64.3 % vs 41.3 %; OR = 2.53 [1.09-5.90]; p = 0.03) were significantly associated with severe acute toxicity. CONCLUSION: This study did not find an association between smoking during radiotherapy for HNC and occurrence of severe acute toxicities.

RESUMEN

INTRODUCTION: HPV vaccination is recommended in France for girls aged 14 and for those aged 15-23 before sexual debut or who have become sexually active within the previous year. The first aim was to describe vaccination practice among 14-23-year-old girls visiting a general practitioner. A second objective was to investigate factors associated with starting vaccination among girls aged 14-18, in particular the regular practice of Pap-smear screening (PSS) by their mothers. METHODS: A cross-sectional study was conducted from June to August 2009. A total of 87 general practitioners from the large Rhône-Alpes region contributed data on 502 girls/women who came for consultation. RESULTS: 231 (46.0%) of these girls/women had begun the process of HPV vaccination (68.2%, 56.9% and 18.7% of the 14-16, 17-20 and 21-23-year-olds respectively) of whom 139 (60.2%) had received all three doses. 92 girls/women (39.8%) had received only one or two doses at the time of study. However, in 71 (77.2%) cases, the gap between the last dose received and the time of study was within the between-dose interval recommended in the vaccination schedule. GPs reported that 16 (11.5%) had mentioned side effects following injections. Having a mother who practised regular PSS (Odds Ratio 6.2 [1.5-25.8]), having never lived with a partner (4.6 [1.6-13.5]) and vaccination against hepatitis B (3.2 [1.6-6.1]) were found to be independently correlated with the initiation of HPV vaccination among girls/women aged 14-18 years. CONCLUSION: Two years after the start of the programme, only half of girls/women aged 14-23 years had begun the process of HPV vaccination. HPV vaccination status was correlated with PSS in the mother, family status and hepatitis B vaccination. Such information may help to better target girls who are less likely to be vaccinated.

RESUMEN

BACKGROUND: To help prevent cervical cancer, three yearly opportunistic Pap smear screening is recommended in France for women aged 25-65 years. Pap smear screening coverage varies with age and socioeconomic level. The aim of this cross-sectional study was to identify factors associated with a low uptake of Pap smear screening among women with no limited access to healthcare. METHODS: We analyzed data from women aged 25-65 living in the Rhône-Alpes region who completed a self-administered questionnaire given to them by general practitioners between June and August 2008. The questionnaire covered knowledge about cervical cancer and its prevention as well as the women's history of Pap smear screening and other health-related behaviors. The relationship between low uptake of Pap smear screening--defined as not having had the test within the past 3 years--and a range of possible contributing factors was investigated using logistic regression. RESULTS: Of 1186 women with an intact uterus who completed the questionnaire, 89.1% said they had had a Pap smear within the past 3 years. On multivariate analysis, the 10.9% who had not were significantly more likely to live alone (1.76 [1.13-2.74]), to have no children (2.17 [1.31-3.62]), to have never used contraception (5.35 [2.98-9.62]), to have less knowledge about Pap smear screening (3.40 [1.55-7.49]), and to be unvaccinated against hepatitis B (0.55 [0.35-0.87]). CONCLUSION: Despite high overall compliance with Pap smear screening recommendations among women who consulted general practitioners, several factors were significantly associated with a low uptake of the service. Considering these factors may help to refine messages aimed at cervical cancer prevention.

RESUMEN

Based on nationwide data from the French national cancer institute (INCa), we analyzed the evolution of cancer genetics consultations and testing over time, and the uptake of targeted tests in relatives of families with BRCA1/2 or MMR genes mutation. Genetic testing and consultations for familial high-risk individuals are exclusively funded and monitored by the INCa in France. All nationwide cancer genetics centers reported annually standardized parameters of activity from 2003 to 2011. The analysis included a total of 240,134 consultations and 134,652 genetic tests enabling to identify 32,494 mutation carriers. Referral for hereditary breast and ovarian cancer (HBOC) or colorectal cancer predisposition syndromes represented 59 % (141,639) and 23.2 % (55,698) consultations, respectively. From 2003 to 2011, we found a dramatic and steady increase of tests performed for BRCA1/2 (from 2,095 to 7,393 tests/year, P < 0.0001) but not for MMR genes (from 1,144 to 1,635/year, P = NS). The overall percentage of deleterious mutations identified in the probands tested was 13.8 and 20.9 % in HBOC and Lynch syndromes, respectively. Pooled analysis for BRCA1/2 and Lynch syndrome tests showed an inverse relationship between the percentage of mutation detected and the absolute number of tests performed over the time (overall Cochran-Armitage test for trend: P < 0.001). In families with BRCA1/2 or MMR identified mutations, there was an average number of 2.94 and 3.28 relatives performing targeted tests, respectively. This nationwide study shows a lack of referral and genetic testing in Lynch as compared to HBOC syndromes. Only a third of relatives of a proband with a predisposing mutation performed a targeted test. Enhanced information about benefit of genetic testing should be given to clinicians and patients for Lynch syndrome and relatives of a proband carrying an identified predisposing mutation.

RESUMEN

To assess the impact of BRCA1/2 genetic test results on cancer-free women's breast-self-examination (BSE) practices and to prospectively determine their influence on psychological functioning. A prospective longitudinal study on French women's BSE practices and frequencies in BRCA1/2 carriers (N = 217) and non-carriers (N = 313) 1 and 2 years following disclosure of the test results, along with psychological factors predicting BSE practices. Before disclosure, BSE was practised by 47.2% of the women, and increased to 57.3% 1 year later. No change in the women's practices was noted between 12 and 24 months after the test. Carriers and non-carriers practicing regularly BSE at baseline were, respectively 8 to 6 times more likely to be practising BSE regularly at 12 months after being tested. Among the carriers, having fewer depressive symptoms at baseline and believing in the ability of BSE to detect breast cancer were found to be the most decisive factors associated with BSE practices 1 year after disclosure, following adjustment for BSE baseline practices. Among the non-carriers, believing in the ability of BSE to detect breast cancer, greater post-test anxiety, and a higher perceived risk of breast cancer were found to be predictors of post-test BSE practices after adjusting for BSE baseline practices. In France, where performing BSE is neither mandatory nor recommended, an increase in BSE practices was found to occur after disclosure of women's genetic test results, regardless of their carrier status.

RESUMEN

OBJECTIVES: Acceptance of the human papilloma virus (HPV) vaccine by targeted population will mainly depend on its acceptability among gynaecologists. We examined the perceptions, attitudes and practices of gynaecologists in relation to HPV vaccination 1 year after licensing. POPULATION AND METHODS: From November 2007 to April 2008, a cross-sectional survey was carried among a representative 10% sample of gynaecologists in the French Rhône-Alpes region. Both quantitative (self-administered questionnaire) and qualitative (interview) approaches were used. RESULTS: Among the 52 respondents, 90.4% of gynaecologists reported a favourable opinion about HPV vaccination, 5.8% were uncertain and 1.9% was opposed (one did not answer). The main justification for a favourable opinion related to the public health effects of the HPV vaccination (cited by 31.9% of those favouring vaccination). The main justification for an uncertain or opposed opinion was the too recent introduction of the vaccine (cited by 100%). During the month preceding the survey, 40.4% had provided HPV vaccination, mainly in 15-23 years old girls (38.5%). The major difficulties in providing HPV vaccination were questions asked by patients (cited by 44.2% of the respondents) and the targeted age of 14 years (13.5%). A total of 87.5% of respondents reported to have discussed with 14-year-old vaccinated girls of Pap-smear and 12.5% of STI prevention. CONCLUSION: One year after HPV vaccine licensing, gynaecologists of Rhône-Alpes region had a favourable opinion about it, despite some difficulties. Little information about STI prevention to vaccinated girls was reported opposite to information about Pap-smear.

RESUMEN

Acceptance of the Human Papillomavirus (HPV) vaccine by targeted populations will depend to a large extent on its acceptability among physicians. We examined the perceptions, attitudes and practices of general practitioners (GPs) in relation to HPV vaccination. From November 2007 to April 2008, a cross-sectional survey was carried out among a representative 5% sample of GPs in the large Rhône-Alpes region of France. Both quantitative (self-administered questionnaire) and qualitative (interview) approaches were used. During the month preceding the survey, 75.6% of the 279 GPs who responded had given at least one HPV vaccination and 47.6% had given a vaccination at the routine target age of 14 years. Overall, 80.8% of GPs reported a favourable opinion about HPV vaccination, 17.4% were uncertain and 1.8% were opposed. The main justification for a favourable opinion related to the public health benefits of the HPV vaccination (cited by 60% of those favouring vaccination). The main justification for an "opposed or uncertain" opinion was the too recent introduction of the vaccine (cited by 43.4%). The major difficulties in providing HPV vaccination were patients' concerns about potential side effects (cited by 37% of the respondents) and the target age of 14 years (28.9%). Interviews suggested that the concern about age may relate to the need, as perceived by GPs, to discuss sexually transmitted infections with adolescent patients. A favourable opinion about HPV vaccination was associated with seeing more female patients per week, younger age, and GPs' intention to recommend hepatitis B vaccination. This representative survey of GPs in a major region of France finds a favourable opinion about the HPV vaccine and widespread use of it, despite some concerns that the recent introduction of the vaccine means that we do not yet fully understand the potential for side effects and about the recommended target age of recipients.

RESUMEN

BACKGROUND: Dicer, a ribonuclease, is the key enzyme required for the biogenesis of microRNAs and small interfering RNAs and is essential for both mammalian development and cell differentiation. Recent evidence indicates that Dicer may also be involved in tumourigenesis. However, no studies have examined the clinical significance of Dicer at both the RNA and the protein levels in breast cancer. METHODS: In this study, the biological and prognostic value of Dicer expression was assessed in breast cancer cell lines, breast cancer progression cellular models, and in two well-characterised sets of breast carcinoma samples obtained from patients with long-term follow-up using tissue microarrays and quantitative reverse transcription-PCR. RESULTS: We have found that Dicer protein expression is significantly associated with hormone receptor status and cancer subtype in breast tumours (ER P=0.008; PR P=0.019; cancer subtype P=0.023, luminal A P=0.0174). Dicer mRNA expression appeared to have an independent prognostic impact in metastatic disease (hazard ratio=3.36, P=0.0032). In the breast cancer cell lines, lower Dicer expression was found in cells harbouring a mesenchymal phenotype and in metastatic bone derivatives of a breast cancer cell line. These findings suggest that the downregulation of Dicer expression may be related to the metastatic spread of tumours. CONCLUSION: Assessment of Dicer expression may facilitate prediction of distant metastases for patients suffering from breast cancer.

RESUMEN

BACKGROUND: The HNPCC syndrome (hereditary nonpolyposis colon cancer) is an inherited condition defined by clinical and genealogical information, known as Amsterdam criteria. In about 70% of cases, HNPCC syndrome is caused by germline mutations in MMR genes, leading to microsatellite instability of tumor DNA (MSI phenotype). Patients affected by the disease are at high risk for colorectal and endometrial carcinomas, but also for small intestine, urothelial, ovary, stomach and biliary tract carcinomas. HNPCC syndrome is responsible for 5% of colorectal cancers. Identification and management of this disease are part of a multidisciplinary procedure. METHODS: Twelve experts have been mandated by the French Health Ministry to analyze and synthesize their consensus position, and the resulting document has been reviewed by an additional group of 4 independent experts. MAIN RECOMMENDATIONS: The lack of sensitivity of Amsterdam criteria in recognizing patients carrying a MMR germline mutation led to an enlargement of these criteria for the recruitment of possible HNPCC patients, and to a 2-steps strategy, asking first for a tumor characterization according to MSI phenotype, especially in case of early-onset sporadic cases. The identification of germline MMR mutations has no major consequence on the cancer treatments, but influences markedly the long-term follow-up and the management of at-risk relatives. Gene carriers will enter a follow-up program regarding their colorectal and endometrial cancer risks, but other organs being at low lifetime risk, no specific surveillance will be proposed.

RESUMEN

Interleukin-2 (IL-2) or/and interferon (IFN) are routinely used for treating patients with metastatic renal cell cancer. However, results have been disappointing, with a majority of treatment failure. Over 6 years, the Groupe Français d'Immunothérapie enrolled 782 patients in successive multicenter trials using cytokine regimens. Univariate and multivariate analyses were performed on this large prospective database to identify prognostic factors for survival. The presence of biological signs of inflammation, short time interval from renal tumor to metastases (<1 year), elevated neutrophil counts, liver metastases, bone metastases, patient performance status (PS), the number of metastatic sites, alkaline phosphatases and hemoglobin levels were predictive of survival outcome. When compared with previous results, our study showed that PS, number of metastatic sites, disease-free interval, biological signs of inflammation and hemoglobin levels can be considered as validated prognostic factors. We also identified four independent factors predictive of rapid progression under cytokine treatment: presence of hepatic metastases, short interval from renal tumor to metastases (<1 year), more than one metastatic site and elevated neutrophil counts. Patients who combined at least three of these factors have >80% probability of rapid progression despite treatment. We think that these results must be taken into account when making the decision to treat with cytokine.

RESUMEN

The familial form of nonmedullary thyroid carcinoma (NMTC) is a complex genetic disorder characterized by multifocal neoplasia and a higher degree of aggressiveness than its sporadic counterpart. In a large Tasmanian pedigree (Tas1) with recurrence of papillary thyroid carcinoma (PTC), the most common form of NMTC, an extensive genomewide scan revealed a common haplotype on chromosome 2q21 in seven of the eight patients with PTC. To verify the significance of the 2q21 locus, we performed linkage analysis in an independent sample set of 80 pedigrees, yielding a multipoint heterogeneity LOD score (HLOD) of 3.07 (alpha=0.42), nonparametric linkage (NPL) 3.19, (P=.001) at marker D2S2271. Stratification based on the presence of at least one case of the follicular variant of PTC, the phenotype observed in the Tas1 family, identified 17 such pedigrees, yielding a maximal HLOD score of 4.17 (alpha=0.80) and NPL=4.99 (P=.00002) at markers AFMa272zg9 and D2S2271, respectively. These results indicate the existence of a susceptibility locus for familial NMTC on chromosome 2q21.

RESUMEN

The Li-Fraumeni syndrome (LFS) is an inherited form of cancer, affecting children and young adults, and characterized by a wide spectrum of tumors, including soft-tissue and bone sarcomas, brain tumours, adenocortical tumours and premenopausal breast cancers. In most of the families, LFS results from germline mutations of the tumor suppressor TP53 gene encoding a transcriptional factor able to regulate cell cycle and apoptosis when DNA damage occurs. Recently, germline mutations of hCHK2 encoding a kinase, regulating cell cycle via Cdc25C and TP53, were identified in affected families. The LFS working group recommendations are the following: (i) positive testing (screening for a germline TP53 mutation in a patient with a tumor) can be offered both to children and adults in the context of genetic counseling associated to psychological support, to confirm the diagnosis of LFS on a molecular basis. This will allow to offer to the patient a regular clinical review in order to avoid a delay to the diagnosis of another tumor; (ii) the 3 indications for positive testing are: a proband with a tumor belonging to the narrow LFS spectrum and developed before age 36 and, at least, first- or second-degree relative with a LFS spectrum tumor, before age 46, or a patient with multiple primary tumors, 2 of which belonging to the narrow LFS spectrum, the first being developed before 36 or a child with an adenocortical tumour; (iii) presymptomatic testing must be restricted to adults; (iv) the young age of onset of the LFS tumors the prognosis of some tumors, the impossibility to ensure an efficient early detection and the risk for mutation carriers to develop multiple primary tumors justify that prenatal diagnosis might be considered in affected families.

RESUMEN

Prophylactic surgery is a major issue for breast/ovarian cancer prone women. Bio-clinical data to help in the decision-making are not sufficient. In this context of uncertainty, physicians' and women's attitudes to prophylactic surgery is information of great value. The physicians' attitudes were assessed by a randomised national sample of practitioners involved in breast and ovarian cancer management. The patients' attitudes were appraised with a pre-consultation self- administered questionnaire presented during a one-year period to all women in five cancer genetic clinics chosen, for their representative geographical locations and their activity level. Consent to prophylactic surgery is higher among physicians than among patients (p < 0.0001). Acceptability of mastectomy is lower than that of oophorectomy in both patients and physicians (p < 0.0001 in both groups). In addition, age at which the intervention is proposed to be performed is a key determinant for both mastectomy and oophorectomy acceptability, in both physicians and patients (p < 0.001 for each comparison). Particularly, the age of 40 years seems to be a critical threshold for the acceptability of prophylactic oophorectomy. In contrast, respondents' age at the time of the survey has no significant effect on the acceptability rate. The higher acceptability rate of prophylactic oophorectomy compared to that of mastectomy observed in the physicians' survey is paradoxical because a more substantial medical impact on life expectancy was expected from the latter. Our results indicate that assumed reduced mortality is not the main criterion steering acceptability. It was anticipated that prophylactic mastectomy should be rarely performed in France.

RESUMEN

Informed probands are key actors for disclosing genetic information to their relatives when a mutation has been identified in the family. The objectives were to study women's attitudes towards the family disclosure of positive breast cancer genetic testing results and to determine the predictive factors of the diffusion patterns observed. A national multi-center cross-sectional survey was carried out at five French cancer genetic clinics during a 1-year period. Self-administered questionnaires were completed after the consultation by 84.5% (398/471) of women attending breast cancer genetic clinics for the first time. Among the 383 respondents who had at least one living first-degree relative to inform, 8.6% would inform none, 33.2% would inform at least one of them, and 58.2% would inform all of them. The sibship would be the most frequently informed blood relatives, sisters in 86.9% and brothers in 79% compared with mother in 71.4%, children in 70.4%, and father in 64.9%. Women of the family would be more frequently informed than men (P < 0.05). After multivariate adjustment, age, the fact to be affected by cancer, the number of daughters, and the emotional disturbance due to cancer in a close relationship were the main determinants (P < 0.05) of the diffusion patterns observed. The first step of the relatives' attendance to genetic counseling and the proband's willingness to disclose breast cancer genetic tests results was high in this study and was clearly dependent on the women's personal and emotional characteristics.

RESUMEN

The cervical cancer screening campaign has been led in three cities in Lyons suburbs from October 1st, 1999 to October 31st, 1999. The objectives of this programme whose title was "Action Femme Santé" (Action Woman Health) were to screen cervical cancer systematically for women who accede with difficulties to smear technique, and to settle in an information, screenings and follow-up system. During the three years, 3,127 smears have been declared and have reached about 2,881 women. The rate of detected disorders is about 2.1%. This campaign has succeeded in its goal about the target public but the participation of health professionals was unsatisfactory because of many obstacles. This implementation of the programme and its results, the weak points and strong points to be kept from such experience, are developed.

RESUMEN

PURPOSE: To tailor postinduction therapy for stage 4 neuroblastoma in children who are older than 1 year at diagnosis according to status after induction. PATIENTS AND METHODS: From March 1987 to December 1992, 99 patients who were consecutively admitted were included in the Lyon-Marseille-Curie East of France (LMCE)3 strategy. After induction with the French Society of Pediatric Oncology NB87 regimen and surgery, patients who were in complete remission immediately proceeded to consolidation therapy with vincristine, melphalan, and fractionated total-body irradiation (VMT). All other patients underwent a postinduction strategy before VMT, either an additional megatherapy regimen or further chemotherapy with etoposide/carboplatin. RESULTS: The progression-free survival (PFS) is 29% at 7 years from diagnosis, which compares favorably with that of a similar cohort of 72 patients previously reported by our group (LMCE1; PFS of 20% at 5 years and 8% at 14 years, P =.004). In the multivariate analysis, only age younger than 3 years at diagnosis (P =.0085) and achievement of complete or very good partial remission after NB87 and surgery (P =.00024) remained significant. The PFS of the 87 patients who were included in the postinduction strategy was significantly better than that of the comparable 62 patients on the LMCE1 study (32% v 11% at 7 years; P =.005). CONCLUSION: The progressive improvements in the LMCE results over the last 10 years suggest that improvements in supportive care measures and increases in each component of this strategy (induction, postinduction, consolidation) may all contribute to increased survival rates.
