Prognostic value of morphology and hormone receptor status in breast cancer - a population based study

We analysed the 5-year relative survival among 4473 breast cancer cases diagnosed in 1990-1992 from cancer registries in Estonia, France, Italy, Spain, the Netherlands and the UK. Among eight categories based on ICD-O codes (infiltrating ductal carcinoma, lobular plus mixed carcinoma, comedocarcinoma, 'special types', medullary carcinoma, not otherwise specified (NOS) carcinoma, other carcinoma and cancer without microscopic confirmation), the 5-year relative survival ranged from 66% (95% CI 61-71) for NOS carcinoma to 95% (95% CI 90-100) for special types (tubular, apocrine, cribriform, papillary, mucinous and signet ring cell); 27% (95% CI 18-36) for cases without microscopic confirmation. Differences in 5-year relative survival by tumor morphology and hormone receptor status were modelled using a multiple regression approach based on generalised linear models. Morphology and hormone receptor status were confirmed as significant survival predictors in this population-based study, even after adjusting for age and stage at diagnosis

Progress in the management and outcome of small-cell lung cancer in a French region from 1981 to 1994

Recent analyses of series of small-cell lung cancer (SCLC) patients included in clinical trials have shown improved survival over time, but it has been impossible to determine whether this was due to selection biases, stage migration, or true therapeutic improvement. To determine if there has been a true improvement of survival over time, we reviewed the medical records of all consecutive patients diagnosed with SCLC between 1981 and 1994 in the Bas-Rhin in France. Among the 787 patients (median age 63), there was no significant period effect for sex, age, or stage. Staging work-ups became increasingly thorough (significant period effect). The mean number of investigations and of tumour sites detected correlated significantly. The chemotherapy rate increased (from 76.4% in 1981–1983 to 91.7% in 1993–1994, P = 10−5) and mediastinal irradiation decreased (to roughly 25% of patients after 1983). Median survival time increased for the overall population from 6.6 months in 1981–1983 to 11.3 months in 1993–1994 (P = 10−5), for patients with limited disease (LD) from 9.2 (P = 0.002) months to 14.0 months, and for those with extensive (ED) disease from 3.5 months to 9.6 months (P = 10−5). Significant independent prognostic factors were disease extent, clinical trial participation, period, type of chemotherapy, and mediastinal irradiation in LD. Survival time has truly improved as ‘state of the art' management of SCLC has changed. © 2001 Cancer Research Campaignhttp://www.bjcancer.co

Non-small-cell lung cancer in a French department, (1982–1997): management and outcome

Addition of chemotherapy to the treatment of non-small-cell lung cancer (NSCLC) resulted in a modest but clear improvement in the survival of selected patients. To ascertain if this translates to improved survival in the whole population of patients, we conducted a retrospective population-based study of a sample of 1738 patients diagnosed with primary NSCLC in a French department between 1982 and 1997. The proportion of women, metastatic cases and adenocarcinoma changed significantly over time, as did their management: use of chemotherapy alone increased from 9.7 to 28.1% (P<0.0001), while the use of radiotherapy alone decreased from 32.2 to 9.4% (P<0.0001). The 5-year survival probability was 15.7 % for all patients and 32.6% for those with resectable disease. The 1- and 2-year survival probabilities were 38.2 and 15.6% in locally advanced disease, and were, respectively, 16.8 and 5.2% in metastatic disease. Disease extent and histological subtype were significant independent prognostic factors. Survival of resectable disease was longer among patients treated with surgery or surgery plus chemotherapy, while better outcomes for locally advanced disease were associated with radiation plus chemotherapy. In metastastic disease, patients treated by classical agent without platin or palliative care only had the shortest survival. Despite changes in treatment in accordance with the state-of-the-art, overall survival did not improve over time. It is not unlikely that more patients with bad PS were diagnosed during the latter end of the study period. This could at least partially explain the absence of detection of an overall improvement in survival

Cancer incidence and mortality in France over the period 1980-2005.

BACKGROUND: The objective of this study was to provide updated estimates of national trends in cancer incidence and mortality for France for 1980-2005. METHODS: Twenty-five cancer sites were analysed. Incidence data over the 1975-2003 period were collected from 17 registries working at the department level, covering 16% of the French population. Mortality data for 1975-2004 were provided by the Inserm. National incidence estimates were based on the use of mortality as a correlate of incidence, mortality being available at both department and national levels. Observed incidence and mortality data were modelled using an age-cohort approach, including an interaction term. Short-term predictions from that model gave estimates of new cancer cases and cancer deaths in 2005 for France. RESULTS: The number of new cancer cases in 2005 was approximately 320,000. This corresponds to an 89% increase since 1980. Demographic changes were responsible for almost half of that increase. The remainder was largely explained by increases in prostate cancer incidence in men and breast cancer incidence in women. The relative increase in the world age-standardised incidence rate was 39%. The number of deaths from cancer increased from 130,000 to 146,000. This 13% increase was much lower than anticipated on the basis of demographic changes (37%). The relative decrease in the age-standardised mortality rate was 22%. This decrease was steeper over the 2000-2005 period in both men and women. Alcohol-related cancer incidence and mortality continued to decrease in men. The increasing trend of lung cancer incidence and mortality among women continued; this cancer was the second cause of cancer death among women. Breast cancer incidence increased regularly, whereas mortality has decreased slowly since the end of the 1990s. CONCLUSION: This study confirmed the divergence of cancer incidence and mortality trends in France over the 1980-2005 period. This divergence can be explained by the combined effects of a decrease in the incidence of the most aggressive cancers and an increase in the incidence of less aggressive cancers, partly due to changes in medical practices leading to earlier diagnoses

COL 3-02 - Les comorbidités liées à l’âge sont associées à l’excès de mortalité lié au VIH chez les patients vivant avec le VIH de 60 ans et plus dans la cohorte Dat’AIDS

National audienceIntroduction Depuis le début de l’ère des traitements antirétroviraux hautement actifs, les patients vivant avec le VIH (PVVIH) vieillissent. Les comorbidités liées à l’âge (CLA) deviennent des causes grandissantes de mortalité dans cette population.L’objectif de cette étude était d’évaluer leur impact sur la surmortalité liée au VIH sur 5 ans chez les PVVIH âgés de 60 ans ou plus suivis dans le cadre d’une large cohorte prospective multicentrique française (Dat’AIDS) à l’ère tardive des antirétroviraux hautement actifs (du 01/01/2008 au 31/12/2012)

Analyse des biomarqueurs dans le condensat de l'air exhalé dans une population de salariés exposés professionnellement au béryllium et/ou ses composés

International audienceMétal incontournable dans les industries de pointe à fortes contraintes thermiques et mécaniques, le béryllium peut provoquer une bérylliose pulmonaire chronique (BPC), précédée par un état de sensibilisation au béryllium (SeBe). La valeur limite d’exposition professionnelle sur 8 heures actuellement en vigueur en France insuffisamment protectrice, l’augmentation prévisible du nombre de sujets professionnellement exposés, la latence longue d’apparition de la BPC et l’absence d’outils standardisés de surveillance médicale justifient l’intérêt d’étudier des biomarqueurs d’exposition et d’effets précoces au niveau de l’organe cible, le poumon. Cette étude propose de les mesurer dans le condensat de l’air exhalé, nouvelle matrice biologique

Conditional Relative Survival of Cancer Patients and Conditional Probability of Death

BACKGROUND: Little information is available on the conditional probabilities of death among patients who survive for >5 years after a diagnosis with cancer. The objective of this study was to estimate the conditional probabilities of death for breast cancer, prostate cancer, colorectal cancer, and lung cancer in France. METHODS: The study included data from the French Network of Cancer Registries from 205,562 patients aged 4% at 10 years. During the 3 years after diagnosis, the probability of death was greater for older patients with breast cancer; then, it decreased less for younger patients compared with older patients, leading to a greater conditional probability of death among younger patients at 4 years and up to 10 years. The annual probability of death in patients with lung cancer decreased for both sexes but remained substantially higher for men than for women, reaching approximately 8% and 5%, respectively, at 10 years. CONCLUSIONS: Further studies would facilitate a better understanding of the observed differences in relative survival within European countrie

Multiple primary cancers and estimation of the incidence rates and trends.

The use of different registration rules from one registry to another, both generally and also for paired organs, leads to variations in the proportion of multiple primary cancers: in men, from 0.4 to 4.9% for the colon, 0.1 to 2.7% for the lung, and 4.1 to 8.6% for the mouth and pharynx. Subjective factors, often impossible to verify, contribute to these variations. The impact on the estimation of incidence rates and trends is not negligible for cancers of the mouth and the pharynx and for all the cancers taken together. The trend towards an increase of cancers of the mouth and pharynx in the Bas-Rhin disappeared when the incidence was expressed taking only the first cancer (incidence by individual) into consideration, and the differences in incidence between the Calvados and the Bas-Rhin registries for the same site also disappeared. In the absence of harmonisation of the rules and methods followed for registration, incidence by individual is the only approach which makes it possible to compare incidence rates and trends between registries
