[One-year survival improvement in lung cancer in France. Results of the prospective real life studies KBP-2000-CPHG and KBP-2010-CPHG]. / Amélioration de la survie à 1 an dans le cancer du poumon en France. Résultats des études prospectives en vie réelle, KBP-2000-CPHG et KBP-2010-CPHG.

INTRODUCTION: The French college of general hospital respiratory physicians (CPHG) has conducted 10 years apart two prospective observational studies to assess changes in the primary lung cancer epidemiology and outcomes, including 1-year mortality. METHODS: In 2000 and 2010, all volunteer adult patients followed in the respiratory department of general hospitals participating in the study were consecutively included if their lung cancer was histologically or cytologically diagnosed between 01 January and 31 December (sample date). Their vital status at least 1 year after inclusion and date of death (if applicable) were collected. RESULTS: Respectively, 5667 and 7051 patients were included in the study in 2000 and 2010 and vital status of 5441 (96.0%) and 6981 (99%) patients known. One-year mortality rate was 61.8% in 2000 and 56.4% in 2010 (P<0.0001). Mortality rate significantly decreased from 2000 to 2010 in non-small-cell lung cancer (60.7% vs. 55.2%; P<0.0001) but not in small-cell lung cancer (66.9% vs. 64.2%; P=0.22). The year of diagnosis was an independent risk factor of mortality (OR=0.84; 95% CI: 0.77-0.91; P<0.0001). CONCLUSION: Although it remains low (43.6% in 2010), life expectancy at 1 year for patients with lung cancer has improved in 10 years. Five-year results are expected to show whether this improvement is maintained or not over time.

[Epstein-Barr virus associated pulmonary lymphoma in Sjögren's syndrome]. / Lymphome pulmonaire associé au virus d'Epstein-Barr au cours d'un syndrome de Gougerot-Sjögren.

UNLABELLED: A 71 year-old man with primary Sjögren's syndrome developed pulmonary opacities within two years of the diagnosis. Videothoracoscopic lung biopsy demonstrated high grade, B-cell, CD20+, large-cell lymphoma, associated with Epstein-Barr virus (RNA EBERs of the virus were expressed by the lymphoma cells). The condition initially improved with rituximab-CHOP treatment, but recurrence of the lymphoma was fatal. CONCLUSION: High-grade B-cell lymphoma associated with EBV can occur in Sjögren's syndrome in the absence of long-term immunosuppressive therapy.

[Metastasis to the breast from non mammary metastasis. Clinical, radiological characteristics and diagnostic process. A report of two cases and a review of literature]. / Métastases au niveau des seins de tumeurs extramammaires. Caractéristiques cliniques, radiologiques et démarche diagnostique. A propos de deux cas et revue de la littérature.

The metastatic involvement of the breast from non-mammary neoplasms is a relatively rare condition: 0.5 to 6% of the breast cancers. All cancers can give breast metastases, several months after the discovery of the primitive tumor or in 25% of the cases in being the first sign. Their clinical and radiological presentation polymorphic installation a problem of differential diagnosis between benign tumor, like the fibroadenomas on the one hand, and malignant tumors of other share. The presence of multiple, bilateral round tumors, superficial without the traditional signs of malignity which one meets with the primitive tumors: irregular margins, spiculations, microcalcifications, posterior cone of shadow is evocative diagnosis. The IRM finds the criteria of malignity specific to the primitive tumor. Pathologic examination completed with immunohistochemical tests is a key point for diagnosis. The search for a primitive tumor is essential, in particular for neuroendocrine carcinoma, stromal sarcoma, and the angiosarcoma which can be primitive tumors of the breast. Treatment is therefore modified, taking into consideration the treatment and prognosis of the primary disease.

[Bronchial aspiration in the typing of bronchopulmonary cancers: apropos of 150 cytobiopsy correlations]. / L'aspiration bronchique dans le typage des cancers bronchopulmonaires: à propos de 150 corrélations cytobiopsiques.

We analysed 150 cases of primary lung cancers investigated by bronchial aspirate and biopsy methods with clinical, radiologic and bronchoscopic findings. Among the 150 cases studied, three were characterized by mixed tumor cell components, thus allowing 153 cyto-histological comparisons. The cytologic and histopathologic typing agreed strictly in 102 cases of 153 (66.7%) and was considered as correct in 40 cases (26.1%). Only cases with divergent evaluation between small-cell carcinoma and non small-cell carcinoma were considered as discordant: such misclassification occurred in 11 specimens (7.2%), including two cases with mixed patterns. The cytologic typing was in agreement with the final diagnosis in all epidermoid carcinomas, adenocarcinomas, large-cell carcinomas and poorly differentiated carcinomas. In small-cell carcinomas, cytology was in agreement with histopathology in 20 of 26 cases (77%), and could only indicate undifferentiated features in four cases (15.4%). The analysis of bronchial aspirate specimens gave reliable typing in 92% of cases, and indicated a better tumor cell differentiation than histopathology in 6.5% of cases. The results obtained show that aggressive treatments can be reliably proposed on the basis of cytologic findings, even without tissue corroboration. This proposal is particularly helpful in cases where biopsy cannot be performed (peripheral lesions) or creates a danger to the patient (iatrogenic hemorrhage).

[Alveolar cancer and localized parieto-alveolar fibrosis]. / Cancer alvéolaire et fibrose pariéto-alvéolaire localisée.

We report a case, cytologically diagnosed, of broncho-alveolar cancer associated with localised interstitial pulmonary fibrosis. This association of fibrosis with bronchiolo-alveolar cancer is classical and a pathogenic affiliation has been deduced by the majority of authors. We review the pathogenesis in relation to recent datas concerning the activation of successive oncogenes: the first stage of carcinogenesis may correspond to the activation of an oncogene coding for a fibroblastic growth factor leading to fibrosis.
