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.

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.

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 patien

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 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.

Background Home-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. Methods Literature 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. Discussion This feasibility study addresses an important aspect of maintenance therapy, that is, patient comfort during protracted home-based chemother, Funding Agencies|Eli Lilly

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., AuthorCount:9

The current paradigm is that untreated lung cancer is invariably and rapidly fatal, therefore the medical community normally dismisses the idea that a patient could live with such a disease for years without any therapy. Yet evidence from lung cancer screening research and from recent clinical series suggests that, although rarely recognised in routine practice, slow-growing lung cancers do exist and are more common than previously thought. Here, current evidence is reviewed and clinical cases are illustrated to show that slow-growing lung cancer is a real clinical entity, and the reasons why management protocols developed in the screening setting may also be useful in clinical practice are discussed. Features suggesting that a lung cancer may be slow-growing are described and appraised, areas of uncertainty are examined, modern management options for early-stage disease are evaluated and the influence that all this knowledge might have on our clinical decision-making is weighed. Further research directed at developing appropriate guidelines for these peculiar but increasingly common patients is warranted., Journal Article, SCOPUS: re.j, info:eu-repo/semantics/published

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.

The village of Karain, Turkey, has the world's highest prevalence rate of malignant mesothelioma (MM). Environmental exposure to erionite is thought to cause the disease. However, it has also been suggested that the disease is mainly genetic. Residents in Karain village were traced from 1990 to 2006. Mineral samples were obtained from stones used in construction of their houses and any fibers present were identified. All women who had moved to the village as brides were traced and their cause of death determined. MM was the cause of death in 52 of 322 villagers, representing 50.5% of all deaths. Only 2 of 8 types of stones used in construction contained erionite, and these stones had been used almost exclusively in the mid-sections of the village, where MM was common. In houses not containing erionite, no cases of MM were observed. Sixty-four women came as brides to Karain from villages where erionite or asbestos is not found. Of the 16 women who have died, 11 (69%) died from MM. The extreme risk of MM in Karain is due to indoor exposure to erionite. The effect of genetic factors on mesothelioma development cannot be evaluated in this study, but is likely to be minor., Journal Article, SCOPUS: ar.j, info:eu-repo/semantics/published

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.

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.
