- Fiber-optic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) were performed on 67 occasions in 57 immunocompromised patients with symptoms consistent with pulmonary infection. Diagnosis was achieved more often in renal transplant patients than in patients with hematological malignancies (85% versus 28%). Culture (bacteria, virus, fungi), staining and microscopy (bacteria, fungi, Pneumocystis carinii (PC)) and antigen detection by indirect immunofluorescence (cytomegalovirus (CMV), respiratory viruses, PC, Legionella) were used for diagnosis. On 20 occasions transbronchial biopsies with histopathologic examination were performed. In addition, serology comprising the herpes group (HHV-6) and respiratory viruses was done. A microbial diagnosis was obtained on 45% of occasions. The most common pathogens found were CMV (31%) and PC (25%). On 22 (33%) occasions a rapid diagnosis of 1 or more microbial agents was obtained within 24 h by conventional staining or indirect immunofluorescence. The clinical relevance of findings of CMV, HHV-6, and Epstein-Barr virus in BAL by polymerase chain detection on 18, 6 and 3 occasions is discussed. On 4 occasions pathogenic bacteria were found. It was not possible to relate findings of coagulase-negative staphylococci, alpha-streptococci and Candida albicans to the pulmonary infection.

Tidskriftsartikel (refereegranskat)abstract
- STUDY OBJECTIVES: In 1996, researchers in Sweden initiated a collaborative randomized study comparing lung volume reduction surgery (LVRS) and physical training with physical training alone. The primary end point was health status; secondary end points included survival and physiologic measurements.DESIGN: After an initial 6-week physical training program, researchers' patients were randomized to either LVRS (surgical group [SG]) with continued training for 3 months, or to continued training alone (training group [TG]) for 1 year.SETTING: All seven thoracic surgery centers in Sweden.PATIENTS: All patients in Sweden with severe emphysema fulfilling inclusion criteria for LVRS.INTERVENTIONS: Patients randomized to surgery underwent a median sternotomy, except for a few patients in whom thoracotomy or video-assisted thoracoscopy were performed. In the TG, supervised physical training continued for 1 year; in the SG, supervised physical training continued for 3 months postoperatively.MEASUREMENTS AND RESULTS: Fifty-three patients were included in each group. Six in-hospital deaths occurred after surgery (12%), and one more death occurred during follow-up. Two deaths occurred in the TG. The difference in death rates between the groups was not statistically significant. Health status, as measured by St. George Respiratory Questionnaire (SGRQ) [total scale score mean difference at 1 year, 14.7; 95% confidence interval (CI), 9.8 to 19.7] as well as by the Medical Outcomes Study Short-Form General Health Survey (physical function scale score mean difference at 1 year, 19.7; 95% CI, 12.1 to 27.3) was improved from baseline in the SG compared with the TG. FEV(1), residual volume, and shuttle walking test values also improved in the SG but not in the TG after 6 months and 12 months.CONCLUSIONS: In severe emphysema, LVRS can improve health status in survivors but is associated with mortality risk. The effects are stable for at least 1 year. Physical training alone failed to achieve a similar improvement.

Hyaluronan in pleural effusions and in serum
- 1991
-
Ingår i: Cancer. - 0008-543X .- 1097-0142. ; 67:9, s. 2410-2414

Tidskriftsartikel (refereegranskat)abstract
- It has been suggested that a high level of hyaluronan (hyaluronic acid, HYA) in pleural fluid is an indicator of malignant mesothelioma. In 78 consecutive patients with pleural effusion of various causes the HYA concentration was measured in pleural fluid samples and in serum. Nine patients had malignant pleural mesothelioma, and in three of them the HYA level in pleural fluid was 100 mg/l or more. In 42 patients with effusions due to metastatic malignancy, the mean HYA in the pleural fluid was 75 mg/l, and in five the HYA level was above 100 mg/l. Cardiac insufficiency caused the effusion in 11 patients, of whom two had a level above 100 mg/l in pleural fluid. Four patients had a serologically confirmed viral infection and had HYA levels in pleural fluid of 8, 157, 335, and 554 mg/l, respectively. One patient had postinfectious effusion with an HYA level in pleural exudate of 748 mg/l, the highest in this investigation. Two patients had benign asbestos pleural effusions, and both had high pleural HYA levels (256 and 490 mg/l, respectively). The serum HYA values were much lower than in the pleural fluid, namely from 15 to 480 micrograms/l; the levels were independent of the levels in the pleural fluid. Thus, a high level of HYA in pleural fluid is not specific for mesothelioma but can occur in other malignant or benign diseases, and a low level does not exclude mesothelioma.

Tidskriftsartikel (refereegranskat)abstract
- Background: Endobronchial lung volume reduction (EBVR) with one-way valves introduced into the most diseased lobe of the lung is a non-invasive method to improve lung function in patients with severe heterogenous emphysema. The problem is to select the right patients for the procedure. Furthermore, the long-term effects have not been reported in most studies.Methods: EBVR was performed in 35 patients with severely handicapping emphysema and with one radiologically clearly enlarged (at least 125%) target lung lobe and clearly visible and complete interlobar fissures on CT. Most of the successful survivors have then been followed for five years.Results: Five (14%) were primary failures (defined as less than 15% increase of FEV1sec) and 10 (28%) were secondary failures (the valves were coughed up or removed for some reason). In the 21 successful 1 patients, the improvement of FEV1sec was in the mean 59%. Over the years, FEV1sec gradually decreased but was still higher 5 years later than initially. Of the successful group, 76% were still alive after 5 years, while only 50% were in the refused or failed groups.Conclusions: With careful selection of patients remarkably good results in lung function can be achieved, and these improvements will last for years though slowly decrease. In addition, the results indicate an improvement in survival with successful EBVR procedure.

One- to Four-Year Follow-Up of Endobronchial Lung Volume Reduction in Alpha-1-Antitrypsin Deficiency Patients : A Case Series
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Background: Lung volume reduction surgery can improve lung function and working capacity in severe heterogeneous emphysema. Endobronchial lung volume reduction (ELVR) performed by one-way valves inserted via a flexible bronchoscope can result in a moderate but significant improvement in lung function and exercise tolerance, eliminating the surgical risks. Objectives: Most studies of this method have excluded patients with alpha(1)-antitrypsin (AAT) deficiency, but small series of cases with positive short-term outcome have been reported. The sustainability of results has been questioned and we here present our experience in AAT-deficient patients treated with ELVR followed up for up to 4 years. Methods: From August 2008 to January 2012, 15 patients were treated with ELVR. Inclusion criteria were homozygotic AAT deficiency, age <80 years, residual volume of 140% or more, forced expiratory volume in 1 s (FEV1) 15-45% of predicted, severe heterogeneous emphysema, symptomsseverely restricting daily life, informed consent and absence of other serious diseases. Results: One patient coughed up valves after 2 months, 1 developed pneumothorax and had valve displacement and subsequent removal, and 1 improved from an FEV1 of 0.62 to 0.84 liters, but after 4 months developed repeated and severe pneumonia and the valves had to be removed. Thus, 12 patients remained and were followed up for at least 1 year. In these patients, FEV1 increased (mean: 54%), the quality of life was much improved, and 2 patients could be taken off oxygen therapy. During the 4-year follow-up, patients demonstrated no significant deterioration in lung function. Conclusion: In carefully selected AAT deficiency patients with severe emphysema, ELVR can be safely performed with encouraging long-lasting results.

Pleural disease during treatment with bromocriptine in patients previously exposed to asbestos
- 1997
-
Ingår i: European Respiratory Journal. - : European Respiratory Society (ERS). - 0903-1936 .- 1399-3003. ; 10:12, s. 2711-2715

Tidskriftsartikel (refereegranskat)abstract
- Bromocriptine, which is used in the treatment of Parkinson's disease, can cause adverse pleuropulmonary reactions. Exposure to asbestos can result in similar lesions. Fifteen patients with former exposure to asbestos, who developed pleural fibrosis after treatment with bromocriptine, were observed independently in Sweden (11 patients) and Australia (four patients). The patients complained of malaise, often associated with weight loss, dyspnoea, and a disturbing cough. Laboratory values included increased erythrocyte sedimentation rate and a low haemoglobin level. Lung function tests showed a restrictive lung function defect. Chest radiographs showed bilateral pleural fibrosis, with small amounts of fluid in some cases. Soon after bromocriptine was withdrawn, the patients improved clinically, and the laboratory values returned to normal. However, in most cases, pleural fibrosis and a restrictive lung function defect persisted to some extent. In conclusion, in patients who develop pleuropulmonary fibrosis whilst being treated with bromocriptine, former exposure to asbestos should be investigated. Conversely, when pleural changes develop in a patient on bromocriptine and with prior exposure to asbestos, the possible causative role of the drug should be discussed. Special follow-up may be indicated when bromocriptine is planned in a patient with previous asbestos exposure, and if symptoms or signs of pleural fibrosis develop, bromocriptine withdrawal should be considered.

Randomized phase II study of gemcitabine and carboplatin +/- sequential docetaxel in non-small cell lung cancer
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Sequential administration of chemotherapeutic drugs might have advantages: additive toxicity is avoided and the individual drugs can be given in full dosages. The Swedish group earlier found the combination of gemcitabine and carboplatin to be effective and with acceptable toxicity. The group therefore decided to add docetaxel in a sequential way in a randomized phase II study. Patients were randomized to either gemcitabine or carboplatin for six cycles or the same regimen for three cycles followed by weekly single agent docetaxel. The primary objective was time to progression (UP). One hundred and twenty-three patients with performance status WHO 0-2 and with earlier un-treated non-small cell lung cancer with measurable stage IIIB disease, not amenable to curative treatment, or stage IV disease without known metastatic spread to the CNS, were enrolled. Hematological toxicity was more common in the GC group but clinically significant bleeding or leucopenic fever occurred only in a minority of patients. No complete responses were noted. Partial response (PR) was observed in 19.3% and 20.8% in the GC and GCD group, respectively. Progression-free survival was 5.6 and 4.8 months and overall survival time 10.6 and 10.1 months in the GC and GCD groups, respectively. Thus, sequential treatment with docetaxel after treatment with gemcitabine and carboplatin did not improve time to progression, response rates, or overall survival.

Tidskriftsartikel (refereegranskat)abstract
- Background: Malignant pleural mesothelioma has a poor prognosis and there is limited effect of treatment. The Nordic Mesothelioma groups decided in the year 2000 to investigate a combination or liposomized doxorubicin, carboplatin, and gemcitabine for this disease in a phase II study.Methods: From January 2001, to December 2003, 173 evaluable patients with biopsy-verified malignant mesothelioma were included. Two patients were lost to follow-Lip, but all the others were followed for at least 4 years or until death.Results: Toxicity was fairly low. There were 56 responses (32.4%), of which 2 were complete; the median time to progression was 8.6 months, and the median overall survival was 13 months. Some patients had their responses 4 to 6 months after last treatment. For 116 patients with epitheloid subtype, median Survival was 17 months. A subgroup of these patients with good performance status, early stage, and age 70 years or less, showed a median survival of 22 months.Conclusion: The treatment yields good results with a high number of responses and long survival, and a low toxicity. The long Survival of the epitheloid subgroup with good prognostic factors is as good as or even better than some studies on "radical" Surgery or multimodal treatment, underlining the need of randomized studies to evaluate such treatment options.

- Introduction: Malignant pleural mesothelioma (MPM) has a poor prognosis and there is limited effect of treatment. Lately, pemetrexed and cisplatin have been established as the standard treatment. Objectives: The present study was planned in 1998, when there was no standard treatment. Single-dose doxorubicine had, in small studies, accomplished remissions, and the Scandinavian Mesothelioma Groups therefore decided to test a liposomized form of this drug, which had shown limited toxicity but good efficacy in a few small studies. Methods: Fifty-four evaluable patients with histologically verified and inoperable MPM were treated with liposomized doxorubicine 40 mg/m2, every 4 weeks for six cycles. Results: In all, 29 patients (54%) received at least six treatments. The quality of life remained good during the study. Hematologic toxicity was very low. Palmo–plantar erythema occurred in 11 patients (20%), thereof 7 grade II but none was severe and none was dose-limiting. There were four partial responses (7%). The median time to progression (TTP) was 5 months, the median survival was 12 months, and at 24 months, 22% were still alive. Conclusion: Liposomized doxorubicine has a low toxicity and is well tolerated; there were a remarkably long TTP and a good survival. Thus, despite the low response rate, liposomized doxorubicine remains an interesting drug for the treatment of malignant mesothelioma.

- Rationale: Single-center randomized controlled trials of the Zephyr endobronchial valve (EBV) treatment have demonstrated benefit in severe heterogeneous emphysema. This is the first multicenter study evaluating this treatment approach. Objectives: To evaluate the efficacy and safety of Zephyr EBVs in patients with heterogeneous emphysema and absence of collateral ventilation.Methods: This was a prospective, multicenter 2:1 randomized controlled trial of EBVs plus standard of care or standard of care alone (SoC). Primary outcome at 3 months post-procedure was the percentage of subjects with FEV1 improvement from baseline of 12% or greater. Changes in FEV1, residual volume, 6-minute-walk distance, St. George's Respiratory Questionnaire score, and modified Medical Research Council score were assessed at 3 and 6 months, and target lobe volume reduction on chest computed tomography at 3 months.Measurements and Main Results: Ninety seven subjects were randomized toEBV(n = 65) or SoC(n = 32). At 3 months, 55.4% of EBV and 6.5% of SoC subjects had an FEV1 improvement of 12% or more (P < 0.001). Improvements were maintained at 6 months: EBV 56.3% versus SoC 3.2% (P < 0.001), with a mean +/- SD change in FEV1 at 6 months of 20.7 +/- 29.6% and -8.6 +/- 13.0%, respectively. A total of 89.8% of EBV subjects had target lobe volume reduction greater than or equal to 350 ml, mean 1.09 +/- 0.62 L (P < 0.001). Between-group differences for changes at 6 months were statistically and clinically significant: Delta EBV-SoC for residual volume, -700 ml; 6-minute-walk distance, +78.7 m; St. George's Respiratory Questionnaire score, -6.5 points; modified Medical Research Council dyspnea score, -0.6 points; and BODE(body mass index, airflow obstruction, dyspnea, and exercise capacity) index, 21.8 points (all P < 0.05). Pneumothorax was the most common adverse event, occurring in 19 of 65 (29.2%) of EBV subjects.Conclusions: EBV treatment in hyperinflated patients with heterogeneous emphysema without collateral ventilation resulted in clinically meaningful benefits in lung function, dyspnea, exercise tolerance, and quality of life, with an acceptable safety profile.

Recension (övrigt vetenskapligt/konstnärligt)abstract
- The epidemiology of lung cancer is changing in many parts of the world. In the industrialized countries, there is a trend that the incidence in men is declining, while it is increasing for women. Also, adenocarcinomas are becoming relatively more common, especially among men. The purpose of this study was to investigate whether such trends also occur in Sweden and also to describe other aspects of an unselected lung cancer material today, such as symptoms, stage and smoking habits. In the county of Gaevleborg, Sweden, practically all patients with lung cancer are referred to the lung department, and thus a total material of lung cancer patients with only a minimal selection bias can be studied. All patients with lung cancer in the county from January 1, 1997 to December 31, 1999, were investigated prospectively regarding stage, type of cancer, and symptoms. In all, there were 364 patients, 237 (65.1%) men and 127 (34.9%) women. The mean age for men was 69.8 and for women, 68.1 years. 91.9% of the men and 78.6% of the women were smokers or ex-smokers. In general the men were heavier smokers than were the women (P<0.0001). Adenocarcinoma was the most common subtype found in women and squamous cell carcinoma in men. The excess of adenocarcinoma in women was due to never-smoking women; for smoking and ex-smoking men and women, the proportion of adenocarcinomas was the same. In all, 240 patients (68.0%) were diagnosed at Stage IIIb (27.2%) or IV (40.8%), with no significant differences between the sexes. The most common first symptom was cough. Only 7.0% of patients were asymptomatic. In conclusion, the trend of an increasing proportion of adenocarcinoma in lung cancer is seen also in Sweden. A depressingly high percentage of patients present in late stages and are thus inoperable.

- An increasing proportion of cancer patients are aged >65 years and many are aged >70 years. Treatment of the elderly with lung cancer has, therefore, become an important issue; so we performed a retrospective study of our patients to demonstrate how elderly patients with NSCLC are treated in real-life, clinical practice. All patients aged ≥70 years with NSCLC at our department were reviewed retrospectively. In total, 1059 patients (50.8% of all NSCLC patients). Of these patients, 243 (22.9%) received chemotherapy, 164 (70.4%) of whom were treated with a platinum doublet using carboplatin. Second- and third-line chemotherapy were given to 31.4% and 13.9% of patients, respectively. Median overall survival was 289 and 320 days for male and female patients, respectively. Patients with performance status (PS) 0 experienced significantly better survival than patients with PS1 or PS 2: 410, 314, and 204 days, respectively. Age was of less importance, with patients aged 70-79 years versus those aged ≥80 years. Treatment of elderly NSCLC patients with chemotherapy is feasible if they have a good PS and appears to prolong survival. In this study, we found no significant differences in survival either between age groups or genders.

- Background: Lung cancer (LC) is the leading cause of cancer-related death worldwide, including Sweden. Several studies have shown that socioeconomic status affects the risk, treatment, and survival of LC. Due to immigration after Second World War, foreign-born people constitute 12.5% of the Swedish population. We wanted to investigate if there were any differences in LC management, treatment and survival among the foreign-born Swedes (FBS) compared to the native Swedish population (NatS) in Stockholm.Material and methods: A retrospective analysis of all patients diagnosed with non-small cell lung cancer (NSCLC) at the Department of Respiratory Medicine and Allergy, Karolinska University Hospital, Solna from 1 January 2003 to 31 December 2008 was made. In all, 2041 cases of LC were diagnosed, thereof 1803 with NSCLC. Of these, 211 (11.7%) were FBS.Results: The mean age of NatS and FBS patients was 69.9 years, median 70 (range 26-96) and 66.0 years, median 66 (range 38-94), respectively (p<0.001). In all, 89.8% of NatS and 90.0% of FBS were either smokers or former smokers. Adenocarcinoma was the most common subtype in both groups (NatS 54.7%, FBS 48.3%). In 140 (8.8%) of the NatS and 17 (8.1%) of the FBS the diagnosis was clinical only. There were no significant differences in stage at diagnosis, nor in performance status (PS) or different therapies between the groups. The median overall survival time for the NatS was 272 days and for FBS 328 days, again no significant difference. However, the median overall survival time for female NatS was 318 days and for female FBS 681 days (p=0.002).Conclusion: FBS patients were significantly younger than NatS at diagnosis, and female FBS lived longer than female NatS, but otherwise there were no significant differences between NatS and FBS patients with LC regarding diagnosis, treatment, and survival.

- Background/Aim: Globally, an increasing proportion of cancer patients are aged >65 years and many are aged >70 years. Treatment of the elderly with lung cancer has, therefore, become an important issue. We performed a retrospective study of our patients to demonstrate how octogenarians with non-small cell lung cancer (NSCLC) are treated in real-life clinical practice. Patients and Methods: This was a retrospective observational study of all elderly (>= 80 years) patients with NSCLC referred to the Department of Respiratory Medicine and Allergy, Karolinska Hospital, Sweden, 2003-2010, and followed until June, 2016. Results: In total, 452 patients, 216 (47.8%) men and 236 (52.2%) women, were included. The mean and median age was 83 years; 28 (6.2%) were aged 90 years or more. Current or former smokers constituted 91.1%, with men having smoked more (p<0.001). There was no difference in performance status (PS) between genders with PS 0-1 in 45.4%, PS 2 in 25.6% and PS3-4 in 29%. About a third each was diagnosed in stages 1-II, III and IV. Adenocarcinoma was most common (45.6%), 18.1% had squamous cell carcinoma, while histological diagnosis was unavailable in 23.2%. Best supportive care (BSC) was given only to 209 patients (46.2%). Potentially curative therapy was administered to 16.5% of men and 20.3% of the women with surgery performed in 35 patients (7.8%) and stereotactic body radiation therapy (SBRT) in 48 patients (10.6%). Chemotherapy was given to 51 patients (11.2%) and palliative radiotherapy to 77 (17.0%). Second-line chemotherapy was given in 4% and third-line in 1.5%. Only one patient received fourth-line. Male patients who received chemotherapy survived a mean of 281 days and for female patients it was 332 days (not significant). Median overall survival (OS) was 115 days in patients receiving BSC and 362 days in patients given any therapy. Patients who underwent surgery for stage I-II had a median OS of 5.6 years compared to 3.5 years for patients given SBRT. Conclusion: Treatment of NSCLC patients 80 years and older with any modality is feasible with a good PS. Survival is fairly good with surgery or SBRT.

- Study objectives: Autopsy studies have shown that a sizeable portion of lung cancers are never diagnosed and thus not entered into any cancer registry.Design: In 1997, we decided to make all available efforts to find all patients with lung cancer who had not been registered previously.Setting: The local hospitals in the county of Gävleborg, Sweden.Patients: All patients with lung cancer diagnosed in the county from 1997 to 2000.Interventions: In meetings with all the general practitioners of the county, these were asked to refer all suspected cases as early as possible, including those with a seemingly dismal prognosis. This initiative was also covered by the newspapers and the local television station.Measurements and results: From 1997 onwards, the incidence of lung cancer in the county was found to be 40–50 per 100 000 inhabitants compared with an incidence of about 30 during the ten preceding years. This difference is significant in time (P<0.0001) and is compared with the incidence of lung cancers in four neighboring counties (P=0.002). Conclusions: There can be a considerable number of patients with lung cancer who are never diagnosed. This can explain differences in survival between various countries and this will also affect the results of screening programs, since the control groups will also include a number of lung cancer cases which will never be recognized.

- BackgroundHome-based care in oncology is mainly reserved for patients at the end of life. Regulations regarding home delivery of cytotoxics differ across Europe, with a notable lack of practice guidelines in most countries. This has led to a lack of data addressing the feasibility of home-based administration of cytotoxic chemotherapy. In advanced non-squamous non-small cell lung cancer, pemetrexed is approved as maintenance therapy after first-line chemotherapy. In this setting, patients have the potential to be treated long-term with maintenance therapy, which, in the absence of unacceptable toxicity, is continued until disease progression. The favourable safety profile of pemetrexed and the ease of its administration by 10-minute intravenous infusion every 3 weeks make this drug a suitable candidate for administration in a home setting.MethodsLiterature and regulations relevant to the home-based delivery of cytotoxic therapy were reviewed, and a phase II feasibility study of home administration of pemetrexed maintenance therapy was designed. At least 50 patients with advanced non-squamous non-small cell lung cancer, Eastern Cooperative Oncology Group performance status 0–1 and no progressive disease after four cycles of platinum-based first-line therapy are required to allow investigation of the feasibility of home-based administration of pemetrexed maintenance therapy (500 mg/m2 every 3 weeks until progressive disease or unacceptable toxicity). Feasibility is being assessed as adherence to the home-based administration process (primary endpoint), patient safety, impact on patients’ quality of life, patient and physician satisfaction with home care, and healthcare resource use and costs. Enrolment of patients from the UK and Sweden, where home-based care is relatively well developed, commenced in December 2011.DiscussionThis feasibility study addresses an important aspect of maintenance therapy, that is, patient comfort during protracted home-based chemotherapy. The study design requires unusual methodology and specific logistics to address outcomes relevant to the home-delivery approach. This article presents a study design that offers a novel and reproducible model for home-based chemotherapy, and provides an up-to-date overview of the literature regarding this type of treatment.

- Objective: To examine the incidence and epidemiology of malignant mesothelioma in immigrants from Karain where there is an extraordinarily high incidence of mesothelioma, Cappadocia, Turkey, to Stockholm, Sweden, and their children over 20 years of age born in Stockholm, i.e. two genetically similar populations with and without erionite exposure.Methods: This survey was conducted as a retrospective cohort study. Standardized average annual mesothelioma incidence rates (AAMIRs) and mesothelioma standardized incidence ratio (mSIR) were calculated. Cox regression analysis was used to determine the importance of different factors related to mesothelioma risk.Results: The cohort consisted of 337 people, 203 of whom were born and/or lived in Karain before immigrating to Sweden (erionite-exposed), and 134 who were born in Stockholm (erionite-unexposed). There were 69 deaths, 42 (61%) due to mesothelioma, and two patients with the disease who were still alive. Of these 44 patients, 22 were men. All mesothelioma patients were in the erionite-exposed group. In the age group 30-49 years, mesothelioma developed in 11 of 38 (29%) with erionite exposure, while there were no cases among 86 persons in the non-exposed group. For men, the AAMIR was 253.9 per 100,000 persons in the whole cohort, and for women, it was 350.9. The mSIR was 71.9 for men and 393.1 for women. Exposure to erionite exceeding 20 years and age over 40 years were associated with increased mesothelioma risk.Conclusion: Exposure to erionite is the leading cause of mesothelioma in Karain villagers, and genetic factors are probably of minor importance.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Diagnosis of malignant mesothelioma is challenging. The first available diagnostic material is often an effusion and biochemical analysis of soluble markers may provide additional diagnostic information. This study aimed to establish a predictive model using biomarkers from pleural effusions, to allow early and accurate diagnosis. Patients and Methods: Effusions were collected prospectively from 190 consecutive patients at a regional referral centre. Hyaluronan, N-ERC/mesothelin, C-ERC/mesothelin, osteopontin, syndecan-1, syndecan-2, and thioredoxin were measured using ELISA and HPLC. A predictive model was generated and validated using a second prospective set of 375 effusions collected consecutively at a different referral centre. Results: Biochemical markers significantly associated with mesothelioma were hyaluronan (odds ratio, 95% CI: 8.82, 4.82-20.39), N-ERC/mesothelin (4.81, 3.19-7.93), CERC/mesothelin (3.58, 2.43-5.59) and syndecan-1 (1.34, 1.03-1.77). A two-step model using hyaluronan and N-ERC/mesothelin, and combining a threshold decision rule with logistic regression, yielded good discrimination with an area under the ROC curve of 0.99 (95% CI: 0.97-1.00) in the model generation dataset and 0.83 (0.74-0.91) in the validation dataset, respectively. Conclusions: A two-step model using hyaluronan and N-ERC/mesothelin predicts mesothelioma with high specificity. This method can be performed on the first available effusion and could be a useful adjunct to the morphological diagnosis of mesothelioma.

- Black smoke lung disease - a new disease in Sweden We describe two elderly female patients, immigrants to Sweden from Afghanistan, with intensive longtime exposure to smoke from biomass, and who presented with bronchial stenosis and severe bronchial obstruction. CT and X-ray showed bizarre perihilar infiltrates in the lungs. Bronchoscopy revealed black narrow bronchi with a middle lobe stenosis in one of the patients. These findings indicate the diagnosis bronchial anthracofibrosis (BAF). The here described findings are seen mainly in elderly never-smoking women from developing countries who have spent years cooking food in poorly ventilated kitchens. With increased immigration from these countries such cases will be seen in industrialized countries as well. Active tuberculosis must always be excluded but otherwise no more active investigations such as biopsies are warranted. We suggest that this disease should be termed »black smoke disease« to differentiate it from coal workers' pneumoconiosis, silicosis, and other classical occupational diseases which can have similar clinical and radiological pictures. This term is easily understood even by non-medical persons and illustratess both the etiology and the black bronchi.

- Aim: To evaluate weekly, induction chemotherapy followed by weekly concomitant chemoradiotherapy in a multicentre phase II study of patients with wiresectable stage III non-small cell lung cancer (NSCLC; stage wet IIIB excluded). Patients (aid Methods: Eligible patients received three weekly cycles of paclitaxel 100 mg/m(2) and carboplatin AUC2 followed by six weekly cycles of paclitaxel 60 mg/m(2) and carboplatin AUC2 in combination with thoracic radiotherapy (2 Gy per fraction and day to a total (lose of 60 Gy), Results: Sixty-four patients (40 males and 24 females) with a median age of 63 Years (range, 43-79 years) entered the study. T and N stage were distributed as follows: T1 2 patients (3.2%). T2 10 patients (15.6%), T3 15 patients (23.4%). T4 37 patients (57.8%), N0 10 patients (15.6%). N1 1 patient (1.6%), N2 26 patients (40.6%), N3 26 patients (40.6%), and N missing I patient (1.6%). Seven patients (10.9%) suffered from grade 314 oesophagitis. Grade 112 oesophagitis occurred in 36 patients (56.3%) and pneumonitis grade 112 occurred in 10 patients (15.6%). Sixty-three patients were evaluated on an intent-to-treat basis. The overall response rate was 74.6%. The median time to progression was 247 days and median overall survival was 461 days. According to subgroup analyses, no statistically signicant differences were noted according to gender, age (<65 vs. >= 65 years), perfromance status, histology, or study centre. Conclusion: Induction chemotherapy followed by concurrent chemoradiotherapy with weekly cycles of paclitaxel and carboplatin is feasible and generates moderate toxicity. Efficacy is comparable to other recently published regimens. However, prognosis remains, ill general, poor for this group of patients and further work to develop better therapy is required.

- Recurrent pleural malignant effusion is a common problem which can be treated by inducing symphysis of the pleural sheets. Many different drugs administered into the pleural space can be used to achieve this. The drugs cause an inflammatory response, which in turn is believed to cause the symphysis. Comparatively little has been published on the degree of pleural inflammation and the systemic response and whether this will affect the outcome. The aim of this study was to describe the systemic inflammatory reaction following instillation of a chemical agent into the pleura and to investigate whether this had any predictive value for the outcome (i.e. the pleurodesis). The markers investigated were simple ones: erythrocyte sedimentation rate, C-reactive protein, and leukocyte count from venous blood samples, and the fever reaction. Eighty-nine prospective patients with malignant pleural effusion who underwent pleurodesis with either talc (48 patients) or quinacrine (41 patients) were included in the study. Symphysis was achieved in 82 patients (92 per cent) and all had a prominent transitional elevation of the inflammatory parameters. The unsuccessful attempts caused negligible or very small elevations, but due to the small numbers only the degree of fever after 8 and 48 h showed a statistically significant difference. In conclusion, pleurodesis causes a systemic inflammation and there is a tendency to a correlation between the success of pleurodesis and the degree of inflammation. High fever and high inflammatory parameters including CRP are due to this inflammatory response and do not indicate infection.
