We investigated the relationship between respiratory symptoms reported at one time and incidence of lung cancer the subsequent 30 years in an urban Norwegian population. A cohort of 19,998 persons, aged 15-70 years living in Oslo, was randomly selected for a respiratory survey in 1972. The response-rate was 89% and 17,670 respondents were followed up. The relationship between respiratory symptoms and lung cancer incidence was investigated separately for each symptom group, symptom score and sex, with adjustment for age, smoking habits and occupational exposure. Lung cancer developed in 352 persons (228 men and 124 women) during follow up. We found a significant positive association between the incidence of lung cancer and cough symptoms in both sexes, asthma-like symptoms among women and dyspnoea when walking uphill among men. The relative risk for lung cancer increased with the number of symptoms reported at baseline and was strongest the first decade and decreased with duration of follow up. This association was more pronounced for non-small cell lung cancer than for small cell lung cancer.

The aim of this study is to compare the prevalence and intensity of symptoms and problems with functioning between women and men with inoperable lung cancer (LC) during 3 months post-diagnosis. One hundred and fifty-nine patients completed the EORTC QLQ C-30+LC13 at three time points: close to diagnosis and prior to treatment, and one, and 3 months later. Descriptive cross-sectional analyses and longitudinal analyses using repeated measure ANOVA were conducted. These patients reported many and intense symptoms and problems with functioning. The most salient finding from the cross-sectional analysis was that women reported both more, and more intense problems with emotional functioning close to diagnosis. Statistically significant improvements over time were found in both men and women with regard to emotional functioning, dyspnea, insomnia, cough, pain in arm/shoulder, while physical functioning, fatigue, constipation, dysphagia, peripheral neuropathy and alopecia deteriorated significantly over time. The longitudinal analyses suggest that, with the exception of emotional functioning, gender differences were not only related to biological sex alone, but were also found to be related to other components of the patients' life situation, such as education, age, civil status and type of LC. Sensitivity to different symptom experiences and responses to those experiences between and within women and men is also necessary in the management of symptoms in patients with inoperable LC.

A 54-year old man was admitted with general fatigue, muscle weakness and dyspnea on effort. Medical examinations led to a diagnosis of small cell lung carcinoma (SCLC) with Lambert-Eaton myasthenic syndrome (LEMS). Marked improvement of SCLC and symptoms of LEMS were recognized twice during chemoradiotherapy. On his third admission, he showed muscle weakness, dysaethesia, and neurodysfunction of the bladder and rectum. We initially considered these symptoms to be due to spinal metastasis because MRI findings showed multiple spinal metastases. However, electoromyogram and nerve conduction study demonstrated that his muscle weakness resulted from LEMS though dysethesia and neurodysfunction of bladder and rectum were caused by spinal metastasis. We believe that it is important to perform electomyogram and nerve conduction studies, not only radiographic findings, to detect the "hidden" symptoms of LEMS.

This study described the sleep disturbances of 115 lung cancer patients undergoing their fourth cycle of chemotherapy and examined the impact of sleep disturbances on quality of life and functional performance status while controlling for pain, depression, fatigue, and dyspnea. Sleep disturbance and quality of life were assessed by the Pittsburg Sleep Quality Index (PSQI), and European Organization for Research and Treatment Quality of Life Questionnaire-Cancer 30 (EORTC), respectively. Data were also collected on covariates of sleep disturbance: performance status, pain, fatigue, depression and dyspnea. Patients' mean PSQI global scores for days with chemotherapy (6.86+/-3.83) and for days without chemotherapy (6.23+/-3.47) were both higher than the cut-off of 5, indicating poor quality of sleep during the fourth cycle of chemotherapy. After controlling for covariates, sleep disturbance was significantly associated with impaired cognitive function (EORTC) and poorer functional status. Our results suggest that clinicians should routinely assess sleep problems in lung cancer patients.

The aim of this study was to evaluate the symptomatic and endoscopic responses as well as the toxicities in 158 patients with endobronchial lung cancer treated with high dose rate endobronchial brachytherapy (HDR-EB). Forty-three patients with stage III NSCLC were treated with 60Gy external beam radiotherapy (ERT) and three applications of 5Gy each of HDR-EB (group A). Seventy-four patients who did not receive previous RT were treated with 30Gy ERT and two applications of 7.5Gy HDR-EB with palliative intent (group B). Forty-one patients with recurrent tumor who were irradiated previously were treated with three applications of 7.5Gy HDR-EB, with palliative intent (group C). In group A, bronchoscopic complete (CR) and overall response rates (ORR) were 67% and 86%, respectively. Symptomatic improvement was obtained in 58% of patients with cough, 77% of patients with dyspnea and 100% of patients with hemoptysis. Two and 5-year survival rates were 25.5% and 9.5%, respectively and the median survival time (MST) was 11 months. In group B, the bronchoscopic CR and ORR were 39% and 77%, respectively and 28% and 72% in group C. The symptomatic response rates were 57% and 55% for cough, 90% and 78% for dyspnea and 94% and 77% for hemoptysis, with a MST of 7 and 6 months in Groups B and C, respectively. Eighteen patients (11%) died of fatal hemoptysis (FH) with the median time to this event of 7 months. Treatment intent (p<0.001), total BED (p<0.001) and the number of HDR-EB fractions (p<0.001) were significant prognostic factors for FH. HDR-EB provides effective palliation in relieving the symptoms of patients with endobronchial lung cancer, however, there is a risk of developing FH that is associated with a high BED and multiple HDR-EB applications.

Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular locations of the extremities, affects young and middle-aged adults, with no difference in distribution between the sexes, and has well-documented radiologic manifestations. Pleuropulmonary synovial sarcoma can arise in the chest wall, heart, mediastinum, pleura, or lung, and it shares patient demographics and several imaging features with its soft-tissue counterpart. Patients present with a cough, chest pain, or dyspnea. On chest radiographs, PPSS typically appears as a sharply marginated mass with uniform opacity, based in the pleura or in the lung, and often accompanied by an ipsilateral pleural effusion. Computed tomographic images show a well-circumscribed, heterogeneously enhanced lesion without associated involvement of bone and without calcifications (except in the case of a chest wall primary tumor). Magnetic resonance imaging provides superior demonstration of nodular soft tissue and multilocular fluid-filled internal components of PPSS, in addition to peripheral rim enhancement after the intravenous administration of a gadoliniumbased contrast material such as gadopentetate dimeglumine. Current treatment consists of surgical resection followed by chemotherapy, radiation therapy, or both.

It is unusual for a malignant lung tumor to present clinically as a cystic lesion. A case of large cell carcinoma of the lung mimicking pulmonary hydatid cyst is reported herein. The patient was a 65-year-old male who presented with history of slowly progressive breathlessness and painful swelling over the left chest wall. Computed tomography of the chest showed a well defined cystic lesion in the left upper lobe with outward extension through the left 2nd-3rd intercostal space in the absence of bony destruction. The patient was found to have positive serological test for Echinococcus granulosus and therefore the preoperative diagnosis was that of complicated pulmonary hydatid cyst. Intra-operative findings included presence of a large cavity filled with necrotic material and "daughter cysts". Dense adhesions between the cavity wall and the thoracic cage prevented complete surgical resection. Histopathological evaluation of the excised specimen showed large cell carcinoma. The case highlights the fact that a lung carcinoma may rarely have clinical, radiological, and serological features similar to those of a pulmonary hydatid cyst.

Patients affected with early stage (IA-IB) non-small cell lung cancer (NSCLC), deemed medically inoperable, are usually treated by conventional 3D-CRT, with poor results in terms of local tumour control and survival. Hypofractionated stereotactic body radiation therapy (SBRT) appears to be a valid alternative option, with high rates of local control and promising survival rates according to recent reported series. We herein report the final results of a prospective phase II trial of SBRT in 62 stage I NSCLC patients, homogeneously treated with three fractions of 15Gy each, given every other day during a 1 week time, up to a total dose of 45Gy; dose was prescribed to the 80%-isodose encompassing planning target volume. Patients were immobilized in a dedicated stereotactic body frame; margins around gross tumour volume were 5mm in the axial plane and 10mm in the longitudinal direction. Median age was 73.7 years. A pathologic confirmation of NSCLC was obtained in 64.5% of patients. Forty-three patients had stage IA and 19 stage IB disease. The majority of patients did not experience any toxicity; mild skin reactions, fatigue, dyspnea/cough or transient thoracic pain were recorded in approximately 10% of patients. With a median follow-up time of 28 months, 2 patients experienced an isolated local relapse, 4 an isolated nodal relapse and 15 a systemic failure. At 3 years, local control rate was 87.8%, cancer-specific survival 72.5%, overall survival 57.1%, with 8 out of 20 non-cancer related deaths. In multivariate analysis, tumour volume was associated with a better outcome. In our series, SBRT was well tolerated and confirmed its efficacy, with local control and survival rates globally superior to those reported using conventional radiotherapy. A longer follow-up is needed in order to establish a correct comparison with surgical series, and to fully ascertain a potential negative impact of SBRT on comorbidities of such a fragile patients population.

The intrathoracic growth of the tumor causes several severe symptoms as cough, dyspnea, chest pain, hemoptysis, hoarseness, anorexia/nausea, and dysphagia. In patients with manifest or threatening symptoms radiotherapy (RT) as an effective measure should be implemented into the management concept. Palliative RT radiotherapy prefers short hypofractionated schemas (e.g. 10 x 3 Gy, 4 x 5 Gy, 2 x 8 Gy, 1 x 10 Gy). Careful radiation planning supports the precision of palliative RT and reduces significantly the complication rate. A good response and prolonged palliation effects (6-12 months) can be achieved in many cases. However, the minimum biologically equivalent dose should not be less than 35 Gy. RT produces a good outcome in all types of metastases of lung carcinoma. In emergencies like VCSS or spinal cord compression RT should be initiated immediately. The selection of the optimal therapy for locally advanced lung carcinoma with malignant airway obstruction is difficult. Both brachytherapy and percutaneous irradiation are effective, however published results including local a sum of response, functionality and life quality demonstrates more benefit by percutaneous RT. Due to different physical properties of these two methods the combination of brachytherapy and external beam irradiation may be advantageous.

Pulmonary carcinoma was diagnosed in an 18+-year-old captive female great horned owl (Bubo virginianus). The owl presented with a history of progressive weakness and sudden onset of frank blood in the droppings. On physical examination, the owl had multiple white to yellow plaques in the oral cavity, decreased air sac sounds on the right side, dyspnea (during manual restraint), and reduced pectoral musculature. Whole-body radiographs revealed obliteration of the right-sided air sacs, a soft tissue plaque/density in the left caudal thoracic air sac, soft tissue opacity over the coelomic organs, and increased medullary opacity in the distal right humerus. The owl died during anesthetic recovery, and the body was submitted for necropsy. Although the clinical signs, physical examination results, radiographic signs, and gross pathology supported a diagnosis of mycotic infection, such as aspergillosis, histopathology confirmed pulmonary carcinoma with metastases to the air sacs and humerus.
