Abstract
Both the pre-apoptotic exposure of calreticulin (CRT) and the post-apoptotic release of high-mobility group box 1 protein (HMGB1) are required for immunogenic cell death elicited by anthracyclins. Here, we show that both oxaliplatin (OXP) and cisplatin (CDDP) were equally efficient in triggering HMGB1 release. However, OXP, but not CDDP, stimulates pre-apoptotic CRT exposure in a series of murine and human colon cancer cell lines. Subcutaneous injection of OXP-treated colorectal cancer (CRC), CT26, cells induced an anticancer immune response that was reduced by short interfering RNA-mediated depletion of CRT or HMGB1. In contrast, CDDP-treated CT26 cells failed to induce anticancer immunity, unless recombinant CRT protein was absorbed into the cells. CT26 tumors implanted in immunocompetent mice responded to OXP treatment in vivo, and this therapeutic response was lost when CRT exposure by CT26 cells was inhibited or when CT26 cells were implanted in immunodeficient mice. The knockout of toll-like receptor 4 (TLR4), the receptor for HMGB1, also resulted in a deficient immune response against OXP-treated CT26 cells. In patients with advanced (stage IV, Duke D) CRC, who received an OXP-based chemotherapeutic regimen, the loss-of-function allele of TLR4 (Asp299Gly in linkage disequilibrium with Thr399Ile, reducing its affinity for HMGB1) was as prevalent as in the general population. However, patients carrying the TLR4 loss-of-function allele exhibited reduced progression-free and overall survival, as compared with patients carrying the normal TLR4 allele. In conclusion, OXP induces immunogenic death of CRC cells, and this effect determines its therapeutic efficacy in CRC patients.

Abstract
PURPOSE The present study was designed to determine whether the nuclear or cytoplasmic expression of survivin, was related to clinicopathological parameters and survival in sporadic colon carcinomas. METHODS Western blotting of cell fractions and immunocytochemical methodology were used in five human colon cancer cell lines. Immunohistochemical study was performed in formalin-fixed paraffin-embedded section from 46 patients with sporadic colorectal adenocarcinomas with a polyclonal antibody directed against survivin. Apoptotic index was evaluated by using the M30 antibody. Survival rates were estimated by the Kaplan-Meier method and compared using the log-rank test. Multivariate survival analysis was performed by the Cox proportional hazards model. RESULTS Western blotting and immunocytochemistry analyses confirmed that survivin could be detected both in the nucleus and the cytoplasm. Immunohistochemical analysis demonstrated that 39% of tumours expressed survivin in the nucleus and 41% in the cytoplasm. No relationship was observed between survivin expression and clinicopathological features. Unexpectedly, the apoptotic index appeared to be linked with high survivin nuclear expression. Overall, 3-year observed survival rate was 73% in patients with cytoplasmic survivin expression versus 48% for negative expression (P = 0.14). Survival was 72% versus 50% for positive nuclear survivin expression versus negative (P = 0.16). After adjustment for age and stage, cytoplasmic survivin expression was a significant prognostic factor. A high level of expression was associated to a better survival: RR = 0.35 [0.13-0.98], P = 0.045. CONCLUSION These results indicate that the analysis of the subcellular expression of survivin is a determining factor to define the prognostic value. Its evaluation, using a polyclonal antibody, might help clinicians in the stratification of patients with colorectal cancer.

Abstract
The assessment of the microsatellite instability (MSI) status in colorectal cancers is presently warranted for three reasons: 1) as a screening tool for hereditary nonpolyposis colorectal cancer, 2) as a prognostic marker, and 3) as a potential predictive factor of chemotherapy response. The aim of this study was to evaluate, on a large scale with tissue samples coming from a number of different sources, the difficulties met with routine use of immunohistochemistry (IHC) and to determine if it really does offer an accurate alternative to PCR genotyping. Colorectal carcinomas from 462 consecutive patients resected in public or private hospitals were assessed for MSI status by two methods: MSI testing (with BAT-26 microsatellite) and IHC detection of hMLH1, hMSH2, and hMSH6 proteins. Of the 398 cancers tested, immunohistochemistry was noncontributory in 42 (10.5%), focal in 9 (2.3%), and discordant with the PCR results in 36 (9%). For these 87 cases, complementary analyses were performed to explain discrepancy. After additional IHC assay with modified processing protocols, 8 cases remained noncontributory, 2 focal, and 28 discordant: 18 microsatellite stability IHC/MSI PCR and 10 MSI IHC/microsatellite stability PCR. For these discordant cases, we performed a multiplex PCR assay on DNA extracted from the frozen sample and BAT-26 was amplified from DNA extracted from the paraffin blocks used for IHC. Four discordant cases were reclassified after PCR multiplex assay (3 as MSI and 1 as microsatellite stability). Five other cases displayed intratumoral heterogeneity and 19 remained discordant. The discrepancy could be partly explained by variable technical protocols of fixation in the different laboratories, leading to variations in staining quality and difficulties in IHC interpretation. This population-based study is the first one to show that IHC is not sensitive and specific enough to be used routinely. Immunohistochemistry analysis of MMR proteins must be performed in standardized conditions and interpreted by confirmed pathologists. It cannot replace PCR as long as protocols are not optimized and harmonized.

Abstract
PURPOSE The identification of groups with a high risk of colorectal adenoma recurrence remains a controversial issue for clinicians. This study was designed to assess the predictive value of initial patient and adenoma characteristics of the three-year recurrence. METHODS The study population was composed of 552 patients with resected colorectal adenomas who completed the European Fiber-Calcium Intervention trial. At both baseline and three-year examinations, the characteristics of adenomas were recorded according to a standardized protocol. The main outcomes measured were the three-year overall recurrence, recurrence of multiple adenomas, recurrence of advanced adenomas (size > or = 1 cm or tubulovillous/villous architecture or moderate/severe dysplasia), and proximal and distal recurrence. RESULTS A three-year recurrence was observed in 122 patients (22.1 percent), and more than one-half of them had recurrent adenomas on the proximal colon. After adjustment for patient characteristics and treatment allocation, the number of adenomas and their proximal location at baseline were the main predictors of recurrence. In comparison with patients who had one or two adenomas on the distal colon, patients with three or more adenomas with at least one of them located on the proximal colon had a much higher risk of overall recurrence (5.3; 95 percent confidence interval, 2.7-10.3), proximal recurrence (8.5; 95 percent confidence interval, 4.1-18), and advanced adenoma recurrence (5.5; 95 percent confidence interval, 2.4-12.6). CONCLUSIONS Follow-up colonoscopies in patients with adenomas should include careful examination of the proximal colon. The time interval between follow-up examinations could probably be extended beyond three years in patients who have only one or two distal adenomas.

Abstract
Structural changes that might influence the structural integrity of the vessel in response to intravascular brachytherapy (IVB) and stenting were examined, focus being on the importance of neovascularization in rabbit stented arteries. Stents were implanted in the infrarenal aortas of rabbits, immediately followed by gamma IVB or a sham radiation procedure, and the arteries harvested at 6 months. Labelling for von Willebrand factor showed an increase in adventitial and medial neovascularization in irradiated versus control arteries group (5.04+/-0.89 versus 1.51+/-0.23 mm(-2), respectively; p=0.004). Moreover, intramedial haemorrhages (free hemosiderin deposition) and inflammation (macrophages) were only observed in irradiated arteries. No significant change in expression of matrix metalloproteinase 1, 2 or 3 was observed between the irradiated and control group while collagen content decreased in the irradiated versus the control group (10.05%+/-1.48% versus 31.92%+/-3.12%, respectively; p<0.001). The study supports the hypothesis that IVB associated with stenting induces late deleterious effects on the medial layer, characterized by formation of intramural neovessels, haemorrhages and a decrease in collagen content.

Abstract
AIMS The aim of this study was to assess the independent value of pathological criteria in the diagnosis of mismatch repair (MMR)-defective sporadic colorectal cancers. METHODS AND RESULTS Resected colorectal adenocarcinomas (n = 273) were reviewed in order to identify a number of specific morphological features of MMR-defective carcinomas. Of the 273 cases, 35.2% were right-sided and 5.9% were poorly differentiated. Focal extracellular mucin secretion was seen in 5.1% of cases and a stromal follicular reaction in 4.6%. The expression of the two major MMR proteins hMLH1 and hMSH2 was studied by immunohistochemistry. Carcinomas were considered deficient in the MMR system when a loss of nuclear signal in neoplastic cells was observed for one of the proteins. Such an extinction was seen in 37 of the cases (13.6%). The hMLH1 protein was the one most frequently altered (86.5%). After multivariate analysis, three independent factors were significantly associated with MMR deficiency: proximal location [odds ratio (OR) = 9.30; 95% confidence interval (CI) 2.79, 30.98], the presence of a true stromal follicular reaction (OR = 13.60; 95% CI 2.98, 62.00) and poor differentiation (OR = 8.33; 95% CI 1.63, 40.32). CONCLUSIONS These results confirm that sporadic colorectal MMR-defective adenocarcinomas display certain specific morphological characteristics. However, these pathological features are not sufficiently predictive and immunohistochemistry is needed to identify such tumours accurately.

Abstract
Microsatellite instability has been proposed as an alternative pathway of colorectal carcinogenesis. The aim of this study was to evaluate the interest of immunohistochemistry as a new tool for highlighting mismatch repair deficiency and to compare the results with a PCR-based microsatellite assay. A total of 100 sporadic proximal colon adenocarcinomas were analysed. The expression of hMLH1, hMSH2 and hMSH6 proteins evaluated by immunohistochemistry was altered in 39% of the cancers, whereas microsatellite instability assessed by PCR was detected in 43%. There was discordance between the two methods in eight cases. After further analyses performed on other tumoural areas for these eight cases, total concordance between the two techniques was observed (Kappa=100%). Our results demonstrate that immunohistochemistry may be as efficient as microsatellite amplification in the detection of unstable phenotype provided that at least two samples of each carcinoma are screened, because of intratumoural heterogeneity.

Abstract
Post-traumatic fat embolism was disclosed by a picture of alveolar hemorrhage. Acute hypoxemia associated with dense bilateral pulmonary infiltrates was observed in a 21 year-old woman, 4 days after an accident with closed tibial fracture. Cruoric pulmonary thromboembolism was ruled out, as was an acute pulmonary edema. Neither infectious nor immunologic etiology was found. The diagnosis of alveolar hemorrhage was based on bronchoalveolar lavage. Lipid droplets in macrophages stained by "Oil Red O" established the relationship with fat embolism. The outcome was favorable. The association of fat embolism and alveolar hemorrhage has already been reported, but remains rare.

Mutations of the p53 gene are the most common genetic alteration in malignant human tumors. A cyclin-dependent kinase inhibitor, p21WAF1/CIP1, is thought to be an important mediator of p53-induced cell cycle arrest. Although numerous studies have reported p53 expression and mutation in colorectal cancer few of them have correlated p53 expression with that of its downstream effector p21 and with the proliferation index as measured by expression of the Ki67 nuclear antigen. We studied p53, p21 and Ki67 expression by immunohistochemistry and molecular biology in 35 colorectal carcinomas. We compared these findings with each other and with clinical factors. Sixty three percent of tumors expressed p53 whereas seventy one percent expressed p21WAF1/CIP1. In adenocarcinomas, p21 staining was heterogeneous: p21-reactive cells were seen in the most differentiated areas. There was no correlation between p21WAF1/CIP1 and p53 expression, p53 mutation, Ki67 expression or clinical factors such as sex or location of the tumor. On the other hand, there was a statistical relationship between p21 expression and survival: our results indicated an association between high p21 expression and lower stages p21WAF1/CIP1 appears to be induced independently of p53 in these tumors and may be associated with differentiation rather than proliferation.

Abstract
Wegener's granulomatosis (WG) is an inflammatory, destructive, angiotropic lesion. The inflammatory process involves accumulation of macrophages, lymphocytes, and polymorphonuclear neutrophils. We studied 6 lung biopsy specimens from patients with WG to characterize the cellular infiltrate and to analyze the mechanism of immune cell recruitment. We show that lymphocytes accumulating in WG lesions are mostly memory CD4(+)CD45RO(+) T lymphocytes and, although less numerous, CD8(+)CD45RO(+) T lymphocytes. Few if any B lymphocytes or natural killer cells are present within lesions. The chemokine RANTES (regulated upon activation in normal T cells, expressed and secreted) has been reported to recruit memory T lymphocytes and macrophages selectively. We used reverse-transcription polymerase chain reaction, in situ hybridization, and immunohistochemistry to study its production in WG. RANTES was expressed at a higher level in WG lungs than in normal controls, especially around microabscesses. As visualized immunohistochemically in serial sections with anti-RANTES monoclonal antibody, RANTES production was produced mainly by macrophages. Expression of the gene coding for interferon-gamma (IFN-gamma), a potent RANTES inducer, was also studied. Its expression was also much stronger in WG than in controls. Our observations are consistent with a cascade of events leading to the recruitment of immune cells in WG, sequentially involving production of IFN-gamma by T lymphocytes and RANTES production by macrophages, leading to the homing of memory T-helper lymphocytes and macrophages.

Abstract
PURPOSE In patients with neutropenia, thoracic computed tomography (CT) halo and air-crescent signs are recognized as major indicators of invasive pulmonary aspergillosis (IPA). Nevertheless, the exact timing of CT images is not well known. PATIENTS AND METHODS Seventy-one thoracic CT scans were analyzed in 25 patients with neutropenia with surgically proven IPA. RESULTS On the first day of IPA diagnosis with early CT scan (d0), a typical CT halo sign was observed in 24 of 25 patients. At that time, the median number of thoracic lesions was two (range, one to six), and pulmonary involvement was bilateral in 12 cases. The halo sign was present in 68%, 22%, and 19% of cases on d3, d7, and d14, respectively. Similarly, the air-crescent sign was seen in 8%, 28%, and 63% of cases on the same days. Otherwise, a nonspecific air-space consolidation aspect was seen in 31%, 50%, and 18% of cases on the same days. The analysis of calculated aspergillary volumes on CT showed that, despite antifungal treatment, the median volume of lesions increased four-fold from d0 to d7, whereas it remained stable from d7 to d14. Overall, 21 patients (84%) were cured by the medical-surgical approach. CONCLUSION In patients with neutropenia, CT halo sign is a highly effective modality for IPA diagnosis. The duration of the halo sign is short, and it demonstrates the value of early CT. The increase of the aspergillosis size on CT in the first days after IPA diagnosis is not correlated with a pejorative immediate outcome when using a combined medical-surgical approach.

Abstract
Molecular studies have shown that different genetic pathways are involved in the history of colorectal carcinomas. This suggests that a correlation exists between the molecular, clinical and pathological features of tumours. Two large groups can be individualized: the first group is characterized by allelic losses and hyperdiploidy. These LOH (for loss of heterozygosity)-positive tumours represent 80% of colorectal carcinomas. Among them more than two-thirds are located in the distal colon. They have the worst prognosis. The second group has a normal diploid pattern and a phenotypic microsatellite instability without allelic losses. These tumours represent 10-15% of all colorectal carcinomas and about 30% of the right-sided tumours. They are associated with a better prognosis. In the future, it would perhaps be better to classify colorectal carcinomas according to their molecular features rather than to their topographical localizations.

Abstract
Mesenchymal hamartoma is a rare liver lesion. This lesion was found in a 7-month-old girl with high serum alphafaetoprotein serum levels and was composed of loose connective tissue containing a certain number of epithelial cells of biliary or hepatic origin. Immunohistochemical studies showed that cytokeratins 7 and 19 were localized in bile duct epithelium. The ultrastructural study showed that the hamartoma was composed of well differentiated ductal structures surrounded by a myxoid mesenchyma with cysts formed either from degenerative mesenchymal areas or from dilated ducts. Flow cytometric analysis of nuclei from frozen tissue revealed that the lesion was DNA aneuploid, with a DNA index of 1.28.

Abstract
AIMS There is controversy over the value of the pathological classifications of gastric carcinomas in the prediction of patient survival. This study was designed to assess the prognostic value of four widely used pathological classifications, in addition to classical prognostic factors. METHODS AND RESULTS Records from the population-based registry of digestive tract tumours in the department of Côte d'Or (France) have been analysed. All available histopathological slides of gastric cancer resected between 1976 and 1985 were reviewed and classified according to World Health Organization (WHO), Laurén, Ming and Goseki pathological coding systems. A relative survival analysis was performed using a relative survival model with proportional hazard applied to net mortality by interval. WHO, Laurén or Goseki classifications were not found to be independent prognostic factors. In addition to advanced age group, depth of parietal involvement, nodal involvement, presence of metastases, tumour site and gross appearance of the tumour, the Ming's infiltrative type was associated with a lower survival. CONCLUSION This study suggests an independent prognostic value of the Ming subtypes with respect to survival in patients resected for gastric carcinoma.

Abstract
AIMS We present the clinical and histopathological findings of an unusual pulmonary plasmacytoma associated with light chain deposits. METHODS AND RESULTS The tumour was located in the main left stem bronchus 40 mm from the carina. Histologically, it was composed of sheets of well differentiated plasma cells. Large extracellular deposits of amorphous material were observed in the tumour. These deposits were Congo red negative and contained kappa light chains. They were electron dense granular and non-filamentous. No plasmacytosis was identified by bone marrow biopsy and no monoclonal spike was shown by serum and urine electrophoresis. CONCLUSIONS Our case is unusual in being endobronchial and showing light chain deposition.

Abstract
A case of cholangiocarcinoma arising from multiple bile duct hamartomas (von Meyenburg complexes) is reported in a 68-year-old man. This man has been treated for genetic hemochromatosis for 2 years. The diagnosis of cholangiocarcinoma was suspected by a systematic ultrasound test and made through the pathological examination of the resected specimen. Only six cases have already been reported. Our case is peculiar because it occurred on a genetic hemochromatosis.

Abstract
PURPOSE The prognosis of invasive pulmonary aspergillosis (IPA) occurring in neutropenic patients remains poor. We studied whether new strategies for early diagnosis could improve outcome in these patients. PATIENTS AND METHODS Twenty-three histologically proven and 14 highly probable IPAs in 37 hematologic patients (neutropenic in 36) were analyzed retrospectively. RESULTS The most frequent clinical signs associated with IPA were cough (92%), chest pain (76%), and hemoptysis (54%). Bronchoalveolar lavage (BAL) was positive in 22 of 32 cases. Aspergillus antigen test was positive in 83% of cases when tested on BAL fluid. Since October 1991, early thoracic computed tomographic (CT) scans were systematically performed in febrile neutropenic patients with pulmonary x-ray infiltrates. This approach allowed us to recognize suggestive CT halo signs in 92% of patients, compared with 13% before this date, and the mean time to IPA diagnosis was reduced dramatically from 7 to 1.9 days. Among 36 assessable patients, 10 failed to respond (amphotericin B [AmB] plus fluorocytosyne, n = 2; itraconazole + AmB, n = 8) and died of aspergillosis. Twenty-six patients were cured or improved by antifungal treatment (itraconazole with or without AmB, n = 22; voriconazole, n = 4). In 15 of 16 cases, surgical resection was combined successfully with medical treatment. Achievement of hematologic response, early diagnosis, unilateral pulmonary involvement, and highest level of fibrinogen value < 9 g/L were associated with better outcome. CONCLUSION In febrile neutropenic patients, systematic CT scan allows earlier diagnosis of IPA. Early antifungal treatment, combined with surgical resection if necessary, improves IPA prognosis dramatically in these patients.

Abstract
Classic ergolines, such as bromocriptine, methysergide and ergotamine, can induce chronic pleuropneumonitis. We present the cases of eight patients who developed similar changes whilst on other ergolines. In this retrospective case study spanning 1985-1995, clinical data, radiological material, pulmonary function, bronchoalveolar lavage and histopathology were reviewed. Earlier literature on ergoline-induced pleuropulmonary changes was reviewed. Eight middle-aged to elderly individuals of both sexes developed pleuropulmonary changes during long-term therapy with regular dosages of nicergoline (n = 4), dihydroergocristine (n = 3), or dihydroergotamine (n = 1). Bibasilar pleural thickening with or without pleural effusion was present on chest radiographs and computed tomographic (CT) scans in six cases. Increased erythrocyte sedimentation rate was seen in most. Pure interstitial pneumonitis developed in two patients on dihydroergocristine and was reversible in each. Bronchoalveolar lavage was performed in four cases and was abnormal in all, but demonstrated no consistent pattern. Most patients exhibited lung restriction. The outcome was favourable showing slow improvement in all cases following discontinuation of the ergoline. Slight residual pleural thickening was seen in five out of the six cases with pleural involvement. Nicergoline and dihydroergotamine can induce a syndrome of chronic pleural thickening/effusion that slowly improves after drug withdrawal. Dihydroergocristine can induce reversible interstitial pneumonitis.

Abstract
We describe 2 patients who developed pulmonary infiltrates while being treated with piroxicam. There was no satisfactory explanation other than drug induced lung disease for their illness. They had no exposure to pneumotoxic drugs or aerocontaminants. Microorganisms were not cultured in sputum or bronchoaveolar lavage. There was no underlying illness with possible lung involvement. Pulmonary infiltrates developed during piroxicam therapy, disappeared after drug withdrawal and recurred following rechallenge.

Abstract
We identified eight patients (six women and two men) who had pulmonary infiltrates during treatment with minocycline hydrochloride between 1989 and 1992 in French referral centers for drug-induced pulmonary diseases. Clinical files, chest roentgenograms, computed tomographic scans, pulmonary function, and bronchoalveolar lavage data were reviewed. Minocycline treatment was given for acne (n = 4), genital infection (n = 3), and Lyme disease (n = 1). The duration of treatment averaged 13 +/- 5 days (mean +/- SE); the total dose, 2060 +/- 540 mg. Patients presented with dyspnea (n = 8), fever (n = 7), dry cough (n = 5), hemoptysis (n = 1), chest pain (n = 2), fatigue (n = 3), and rash (n = 3). Chest roentgenograms showed bilateral infiltrates in all cases. Pulmonary function was measured in five patients; four had airflow obstruction and two had mild restriction. Blood gas tests demonstrated hypoxemia in seven patients (58 +/- 3 mmHg). Seven patients had blood eosinophilia (1.76 +/- 0.2 x 10(9)/L). Bronchoalveolar lavage (performed in seven patients) showed an increased proportion of eosinophils (0.30 +/- 0.07). The Cd4+/CD8+ ratio was determined in four cases and was low in three. Transbronchial lung biopsy, performed in two patients, showed interstitial pneumonitis in both patients, with marked infiltration by eosinophils in one patient. The outcome was favorable in all patients. Because of severe symptoms, steroid therapy was required in three patients. Rechallenge was not attempted. We conclude that minocycline can induce the syndrome of pulmonary infiltrates and eosinophilia, that presenting symptoms may be severe and may culminate in transient respiratory failure, and that the disease has a favorable prognosis.

Abstract
One-hundred and twenty 6-week-old 257BL/65 mice were fed for 2 or 7 weeks with diets supplemented with different combinations of bile acids and calcium. The effect of calcium, bile acids and the duration of these treatments on proliferative indices of the colonic mucosa was studied with a multiway analysis of variance. In mice not treated with bile acids, a low level (0.1%) of calcium in the diet was related to a significantly higher number of cells in each compartment of the crypt, compared with diets supplemented with 0.5 and 1% calcium (P < 0.01). There was no difference between the groups fed with normal and high calcium diets. Bile acids significantly increased proliferative indices in all animal groups whatever the duration of the treatment; however, this effect was significantly lower in the mice fed with 0.5% and 1% calcium than in those fed with 0.1% calcium (P < 0.01). There was a significant interaction between the effect of bile acids and the effect of calcium regarding the number of labeled cells and the labeling indices. Duration of the treatment had little effect on these indices. The effect of bile acids on colonic proliferative activity could be significantly reduced by calcium supplementation, and this effect was stable with time. Although there was no toxic effect of the highest calcium diet, there was no advantage in increasing the calcium dose beyond 0.5%.

Abstract
Enteritis cystica profunda and diffuse colitis cystica profunda are exceedingly rare conditions. We report here the first case in which these two entities are associated in one patient. This 48-year-old woman presented initially with a solitary ulcer of the rectum and developed later deep ileal and colonic ulcerations with intervening normal mucosa, polypoid masses, and a dense fibrosis of the bowel wall. Colon and ileum specimens demonstrated submucosal mucous cysts and occasionally herniation of mucosal epithelium into the submucosa, which led to the diagnosis of enteritis and colitis cystica profunda. The exact nature of the underlying ileocolonic disease, which necessitated colectomy and extensive ileal resection, remained undetermined although an aggravating role of iterative surgical procedures is possible. Enteritis cystica profunda and diffuse colitis cystica profunda therefore seem to share a common pathogeny and have to be considered as lesions complicating an underlying disease rather than specific and autonomic diseases.

Abstract
Respiratory involvement in patients with inflammatory bowel disease (IBD) has been reported mainly since 1976. This form of involvement should clearly be separated from interstitial lung disease due to sulfasalazine or mesalamine, although the distinction may be difficult in some cases. We report the data of an ongoing Registry containing 33 cases (23 cases receiving no drug therapy) with ulcerative colitis or, less often, Crohn's disease, who developed varied bronchopulmonary problems. In several cases, the exact diagnosis and the relation of the bronchopulmonary disease to IBD had not been established for many years, thus delaying effective treatment with steroids. In most cases (28/33), respiratory involvement followed the onset of IBD (8 of these 28 cases were postcolectomy), and in the remainder, respiratory manifestations predated the IBD. Patterns of involvement included: 1) Airway inflammation, in the form of subglottic stenosis, chronic bronchitis, severe chronic bronchial suppuration, bronchiectasis, and chronic bronchiolitis. In cases with large airway involvement, endoscopy showed exuberant inflammatory tissue in the airways and narrowing of tracheal and/or bronchial lumen. Histologically, airways were heavily infiltrated by a dense aggregate of inflammatory cells, and there were mucosal ulcerations. 2) Varied patterns of interstitial lung disease, mainly bronchiolitis obliterans with organizing pneumonia, and pulmonary infiltrates and eosinophilia. (3) Miscellaneous other forms of involvement including striking neutrophilic necrotic parenchymal nodules (corresponding histologically to sterile aggregates of neutrophils), and serositis. Steroids were very effective in the majority of cases. Inhaled steroids were of durable benefit in patients with chronic bronchitis, but less often so in those with chronic bronchial suppuration, bronchiectasis, or chronic bronchiolitis. Steroids administered orally led to marked improvement in patients with interstitial lung disease and necrotic nodules, but lacked effectiveness in several patients with severe airway inflammation or chronic bronchiolitis. Intravenous steroids were required in the initial management of life-threatening complications such as asphyxiating subglottic stenosis or extensive interstitial lung disease. Bronchial lavages with methylprednisolone were effective in some patients with severe airway inflammation. Patients with IBD can develop varied inflammatory complications in the lung, and a sizable fraction of these complications is steroid-sensitive.

Abstract
BACKGROUND Nilutamide is a new, specific synthetic antiandrogen, released in several countries for the treatment of metastatic carcinoma of the prostate. Eight patients at the University Medical Centre at Dijon and affiliated referring hospitals developed reversible pulmonary opacities and respiratory symptoms while taking the drug. METHODS Records of eight patients who developed new, otherwise unexplained chest opacities while taking nilutamide were reviewed. In each patient a careful aetiological search was made for other environmental or endogenous causes. Six patients underwent bronchoalveolar lavage, and lavage fluid was cultured. Corticosteroids were not given, unless gas exchange was compromised (two patients). RESULTS The eight patients (all male) had had carcinoma of the prostate diagnosed on average 10.2 months earlier. All had improved with nilutamide, with a dramatic decrease of prostate specific antigen levels. Seven had received nilutamide at the recommended dosage of 150 mg/day, and one had received twice that amount. Treatment had lasted on average 113 (range 10-225) days, and the mean cumulated exposure was 21.8 (3-38) grams. The chest radiographs showed bilateral infiltrates, with no consistent topographic predilection. A restrictive lung defect was present in six patients and hypoxia in all (mean arterial oxygen tension (PaO2) 6.6 kPa). Bronchoalveolar lavage showed lymphocytosis in four patients and neutrophilia in two. The outcome was favourable in all patients after they had stopped nilutamide only (five patients), with corticosteroids (two patients) or a simple reduction of nilutamide from 300 to 150 mg/day (one patient). Recovery was associated with improvement of pulmonary function and PaO2. CONCLUSION Nilutamide is associated with interstitial pneumonitis in about 1% of patients and appears reversible.

Abstract
A population-based series of 246 gastric cancer patients operated for cure and who survived the postoperative phase was reviewed to determine prognostic factors after potentially curative treatment. The overall five-year observed survival rate was 34.8%, and the relative survival rate was 43.9%. Previous history of gastric ulceration, tumor location, tumor size, gross appearance, extension within the gastric wall, and number of proximal lymph nodes involved were significantly related to both crude and relative survival rates. Age was a significant prognostic factor when considering crude survival rates, but it had no influence on relative survival rates. Multivariate analysis of crude and relative survival gave similar results except for age. The covariates retained in the final model were, by decreasing importance, extension within the gastric wall, lymph node involvement, gross appearance and tumor location. Combining the two major prognostic criteria, tumor extension through the gastric wall and lymph node involvement, four prognostic categories could be determined with five-year corrected survival rates ranging from 92% in patients with a carcinoma limited to the gastric wall to 17% in patients with more than two positive nodes whatever the extension in the gastric wall. Gross appearance had no influence on prognosis for carcinomas limited to the gastric wall, but had a significant impact on prognosis of more extended carcinomas. From these data, a simple staging system requiring only routinely available pathological data was proposed. This classification could be helpful for planning multicenter clinical trials on this disease where progress in therapy is needed.
