81mKr ventilation lung scans, 99mTc perfusion lung scans and lung function tests were performed in 25 patients with small cell lung cancer during combination chemotherapy in order to characterize the physiological changes in responding patients. After 3 months of chemotherapy 12 patients had obtained complete remission (CR), with total disappearance of all visible tumor tissue at the chest X-ray, 5 had obtained partial remission, 2 had progressive disease and 6 had died. Prior to treatment a mixed pattern of restrictive and obstructive lung function decrease was observed. The patients had a significant decrease in both ventilation and perfusion (P less than 0.01) of the affected lung and a ventilation perfusion mismatch was seen. Three months after initiation of treatment the patients who obtained CR had a statistical improvement (P less than 0.01) of TLC, VC and FEV in 1 sec, rendering them statistically inseparable from a healthy control group. The ventilation of the affected lung in patients obtaining CR increased statistically (P less than 0.01), but only a minor increase in perfusion (P less than 0.1) was seen so that the ventilation-perfusion ratio remained distorted. It is concluded that even though an increase of static and dynamic lung function parameters, including the ventilation of the affected lung, are seen in patients with small cell lung cancer obtaining complete remission during combination chemotherapy, a marked functional decrease of the perfusion and a ventilation-perfusion mismatch remain.

The ability of preoperative quality-of-life and physiologic variables to predict postoperative complications was tested in 117 consecutive patients undergoing thoracotomy for possible or definite lung cancer. Preoperatively, quality of life was globally assessed by the QLI and Sickness Impact Profile. Dyspnea was assessed by the Clinical Dyspnea Index and a modified Pneumoconiosis Research Unit question. Spirometry and maximal exercise testing were carried out in 115 and 46 subjects, respectively. Thirty-seven percent experienced at least one respiratory complication (eg, pneumonia, atelectasis prompting bronchoscopy, pulmonary embolism). Twofold or greater increases in respiratory complications were associated with current smoking (p < 0.05), cancer as the final pathologic condition (p < 0.10), at least moderate dyspnea (p < 0.10), FEV 1 < 60 percent of predicted (p < 0.05), ventilatory reserve < 25 L (p < 0.05), and VO2max < 1.25 L (p < 0.05). Twofold increases in the incidence of any complication (respiratory, cardiac, etc) were associated with age > or = 75 years (p < 0.05) and cancer as the final pathologic condition (p < 0.05). We conclude that simple historic information (age, smoking status, cancer status, dyspnea) indicates the risk of postoperative morbidity. General quality-of-life measures were not good predictors of morbidity. Our findings corroborate the few studies supporting the value of VO2max and suggest that the usefulness of the ventilatory reserve deserves further attention.

We investigated preoperative PaO2 and changes of PaO2/FIO2 (P/F) during the operation in 40 patients with gynecologic malignancies (ovarian cancer (O group) = 14 cases, endometrial cancer (E group) = 14 cases, cervical cancer (C group) = 12 cases). Preoperative chest X-ray and respiratory function test of our patients were within normal ranges (% VC > or = 80, % FEV 1.0 > or = 70). There were no differences among 3 groups in age, height, weight, % VC, or % FEV 1.0. Preoperative PaO2 values in the O group and E group were significantly lower than the normal value (100--age/4). Preoperative PaO2 and P/F values in the O group were significantly lower in comparison with those in the C group. We suggest, therefore, that it is necessary to measure preoperative PaO2 in patients with ovarian and endometrial cancer.

The aim of this study was to evaluate the contribution of bovine pericardial strips (Peri-Strip) to achieve aerostasis within emphysematous lungs. A preliminary evaluation included 15 patients (13 men and 2 women, mean age 57 years) with severe emphysema (mean FEV-1: 28.6 +/- 10.2% of predicted, mean RV: 18.4 +/- 41.3% of predicted). Two patients were on ventilator owing to acute respiratory failure. Indication for surgery was elective surgery for emphysema in 9 patients, emergency surgery for emphysema in 2, and resection for bronchogenic cancer in 4 patients. The various procedures included single aerostasis in 1, unilateral bullectomy in 6, bilateral volume reduction in 4, thoracoscopic wedge resection for peripheral cancer in 1 and lobectomy for cancer in 3 (2 of which underwent simultaneous bullectomy) Peri-Strip were used to buttress the staple lines at the base of bullae, on parenchymatous transsection lines, and on the borders of fissures. One patient who underwent emergency thoracotomy for single aerostasis died 8 days post-operatively due to multiple organ failure. Another patient developed pneumonia which resolved under treatment. Mean duration of air leaks was 5.6 days (0-21, median 8). Two patients required tube thoracotomy for residual effusions. Mean hospital stay was 17 days (6-53; median 16). We conclude that use of Peri-Strip offered a real benefit to 12 patients; no evidence of benefit was noted in 3 patients.

Ewing's sarcoma, one of the most malignant tumors of children and young adults, expresses specific chimeric genes, e.g. EWS-FLI-1, EWS-ERG, EWS-ETV1 and EWS-FEV. In this paper, we extensively characterized a new fusion gene, EWS-EIAF by means of whole cDNA sequencing, RNA blot analysis, DNA blot analysis and chromosomal analysis, and showed it to be available for the diagnosis of Ewing's sarcoma and to participate in the oncogenesis of Ewing's sarcoma. Furthermore, we conducted a genetic analysis of Ewing family tumors in conjunction with immunohistochemical analysis and ultrastructural analysis. Our results demonstrate some limitations of both genetic analysis and histopathological analysis, and establish the relationship between neurogenic phenotypes and chimera genes.

Esthesioneuroblastoma (ENB) is a rare, site-specific, locally aggressive neuronal malignancy so far thought to belong to primitive peripheral neuroectodermal tumour-Ewing's tumour (pPNETs-ETs). Its anatomical location, in addition to morphologic, immunophenotypic and ultrastructural features, suggests its origin in the neuronal or neuroendocrine cells of the olfactory epithelium. However, the cytogenetic and molecular data currently available appear controversial on the presence of the typical translocation t(11;22)(q24;q12) and of trisomy 8, chromosomal changes that characterize the tumours belonging to the pPNETs-ETs. Herein we have analysed five ENB tumour specimens for trisomy 8 by fluorescence in situ hybridization (FISH), for the presence of EWS gene rearrangements by FISH, reverse transcription polymerase chain reaction and Southern blot analyses, as well as for the expression of the Ewing sarcoma-associated MIC2 antigen by immunohistochemistry. Neither EWS/FLI-I, EWS/ERG and EWS/FEV fusion genes nor MIC2 expression were found in any tumour, whereas trisomy 8 was found in one case only. Moreover, DNA from three cases analysed by Southern blot did not show EWS gene rearrangements. Our results support the evidence that ENB is not a member of the pPNETs-ETs.

Ewing sarcoma-specific chromosomal translocations fuse the EWS gene to a subset of ets transcription factor family members, most commonly the FLI1 gene and less frequently ERG, ETV1, E1A-F, or FEV. These fusion proteins are thought to act as aberrant transcription factors that bind DNA through their ets DNA binding domain. Recently, we have shown (K-B. Hahm et al., Nat. Genet., 23: 222-227, 1999) that the transforming growth factor beta (TGF-beta) type II receptor (TGF-beta RII), a putative tumor suppressor gene, is a target of the EWS-FLI1 fusion protein. Here, we also examined effects of EWS-ETV1 and EWS-ERG on expression of the TGF-beta RII gene. We show that relative to the control, NIH-3T3 cell lines stably transfected with the EWS-FLI1, EWS-ERG, or EWS-ETV1 gene fusion express reduced levels of TGF-beta RII mRNA and protein, and that these cell lines have reduced TGF-beta sensitivity. Cotransfection of these fusion genes and the TGF-beta RII promoter suppresses TGF-beta RII promoter activity and also FLI1-, ERG-, or ETV1-induced promoter activity. These results indicate that transcriptional repression of TGF-beta RII is an important target of the EWS-FLI1, EWS-ERG, or EWS-ETV1 oncogene, and that EWS-ets fusion proteins may function as dominant negative forms of ets transcription factors.

Although familial clustering has been described, few studies have quantified the risk of airflow obstruction in siblings of patients with chronic obstructive pulmonary disease (COPD). One hundred fifty-two subjects with airflow obstruction and a low gas transfer factor (but without PiZ alpha(1)-antitrypsin deficiency) were identified and 150 were enrolled in the study. Complete data were obtained from 173 of 221 siblings of these subjects. Forty-four of 126 current or ex-smoking siblings had airflow obstruction (FEV(1)/FVC < 0.7) and 36 also had a FEV(1) < 80% predicted, in keeping with COPD. One hundred eleven current or ex-smoking siblings were matched for age, sex, and smoking history with 419 subjects, without a known family history of COPD, from the European Prospective Investigation of Cancer (EPIC)-Norfolk cohort. The prevalence of COPD was much lower in the EPIC group (9.3%) when compared with the siblings (31.5%; odds ratio, 4.70; 95% confidence interval, 2.63 to 8.41). The odds ratio for COPD in siblings with less than a 30 pack-year smoking history was 5.39 (95% confidence interval, 2.49 to 11.67) when compared with matched control subjects. Taken together these results demonstrate a significant familial risk of airflow obstruction in smoking siblings of patients with severe COPD.

Between 1991 and 2000, 21 patients (16 male and 5 female) underwent 28 cavernostomies for the treatment of pulmonary aspergilloma. The median age was 59.4 years (range 37-85 years). The mean %VC was 59.6 (range 30.4-91.2), and the mean FEV 1.0 was 1.51 ml (range 0.64-2.67 ml). The mean body mass index was 17.6 (range 12.7-23.2). The most common complaint was hemoptysis. The underlying lung disease was tuberculosis in 17 cases, atypical mycobacteriosis in 2, and unclassified in 2. All cases had been diagnosed as complex aspergilloma. The mean surgical duration was 136 minutes (range 85-203 min.) and the mean blood loss during surgery was 242 ml(range 5-810 ml). No death or major complications occurred in the postoperative course. During follow-up, 4 patients died of massive hemoptysis, cancer, respiratory failure or an unknown cause. Relapses of aspergilloma occurred in 9 patients (42.9%). Recavernostomy was performed safely on 5 patients. In conclusion, although the relapse rate of aspergilloma was high after cavernostomy, safe reoperations were performed. Cavernostomy is thus an effective treatment in high-risk patients.

Forced expiratory volume in 1 second (FEV(1)) is a strong risk factor for cardiovascular disease, stroke, lung cancer, and all-cause mortality. One possible explanation for this association is that FEV(1) is a marker of other determinants of mortality risk, such as obesity and physical inactivity. In a population-based cohort study of 12,283 men and women aged 45-74 years from the European Prospective Investigation into Cancer-Norfolk Study recruited in 1993-1997, the cross-sectional association between physical activity and FEV(1) and that between physical activity and change in FEV(1) were analyzed. Indices of physical activity, including participation in vigorous recreational activity, stair climbing, and television viewing, were assessed with a validated questionnaire designed to assess activity in the previous year. Television viewing was negatively associated with FEV(1) in men and women (p < 0.001), whereas stair climbing and participation in vigorous leisure time activities were positively associated with FEV(1) in men and women (p < 0.001). The associations remained after adjustment for known confounders, including age, height, vitamin C, and smoking. Climbing more stairs and participating in vigorous leisure-time activity predicted a slower rate in annual percent decline in FEV(1) (p < 0.004 and p < 0.002, respectively). In conclusion, physical activity is associated with higher levels of FEV(1), whereas television viewing is associated with lower levels.
