In a consecutive series of 326 patients with primary lung cancer, sarcoid reactions were observed in the regional lymph node or resected lung in 7 patients (2.2%). The average age of the 7 patients, 4 males and 3 females, was 54 years, range 45-70. All the patients underwent lobectomy. The sites in which sarcoid reactions were found were the regional lymph node (N) in 3 patients, the lung parenchyma (L) in 2, N and L in 1, and the tumor stroma in 1. The histologic types were adenocarcinoma in 4 patients, squamous cell carcinoma in 2, and small cell carcinoma in 1. Two patients died of recurrence and myocardial infarction, and five patients are alive, range 5-64 months. The patients with lung cancer complicating sarcoid reactions were significantly younger than the control group (p<0.01), and not significant in prognosis. We conclude that the complication of sarcoid reactions do not influence the prognosis, but that the sarcoid reactions may be a local reaction or resistance to cancer cells.

Respiratory transfer impedance (Ztr) measured using the forced oscillation technique requires virtually no patient cooperation and provides a noninvasive approach for acquiring data reflective of lung mechanics. Also, model analysis of Ztr provides reliable estimates of separate airway and tissue properties (1), but only if data out to 64 Hz are acquired. The current study evaluated the clinical utility of Ztr from 1-80 Hz for assessing the degree and type of impaired lung function. Spirometry and Ztr measurements were made on 37 individuals: 11 healthy subjects and 26 patients with lung disease including chronic obstructive pulmonary disease (COPD), asthma, lung cancer, and sarcoidosis. Over the entire patient group, 12 were also smokers. We first established normal ranges for several Ztr features and model estimated mechanical properties. The COPD and smokers groups showed significant differences in portions of their Ztr spectra from that of the healthy group. Key Ztr spectral features included R0, the frequency at which the real part of impedance is zero; and Re4, the real part of impedance at 4 Hz. The key model parameter was airway resistance, Raw. We found Raw, Re4, and R0 to be significantly elevated during disease (p < 0.0005) and to significantly decrease with bronchodilator therapy (p < 0.025). Moreover, we found moderate to strong correlations between R0, Raw, and Re4 versus FVC and R0 versus FEV1. After bronchodilator, changes in R0, Re4, and Raw were correlated with changes in several spirometric indices. The R0 feature has not been previously evaluated since it is typically above 32 Hz (well above 32 Hz in diseased individuals) and not encompassed in previous clinical studies.

Fibroblasts play a crucial role in progressive lung fibrosis, acting not only as target cells but also as effector cells. To clarify these functions in sarcoidosis, lung fibroblasts from Japanese sarcoid patients were studied for their proliferative capacity and cytokine productivity. Fibroblasts were cultured from transbronchial lung biopsy specimens from seven patients with sarcoidosis. As a comparison, fibroblasts from open lung biopsy specimens of four patients with idiopathic pulmonary fibrosis (IPF) were studied. For controls, fibroblasts were cultured from specimens of normal resected lung tissue of five patients with localized lung cancer. The proliferative activity of cultured fibroblasts from patients with sarcoidosis was highest among the three groups (p < 0.05). However, the proliferative capacity in all groups was suppressed when fibroblasts were cultured with interleukin-1beta (IL-1beta). No significant differences were noted in the degree of inhibition among the three groups. Addition of interferon-gamma (IFN-gamma) also resulted in inhibition of fibroblast growth in all groups, but the degree of inhibition was significantly greater in both the sarcoid and IPF groups than in controls (p < 0.05). The amount of interleukin-6 (IL-6) in the culture supernatants from sarcoid fibroblasts cocultured with IL-1beta was significantly higher than in controls. Sarcoid fibroblasts are not only proliferatively active but also possess effector cell function to produce cytokines. IL-6 may enhance the immunologic reaction to sarcoidosis and cause the disease to become chronic. IFN-gamma suppresses proliferation of sarcoid fibroblasts and may prevent fibrotic changes of the lungs in the Japanese sarcoid patients.

The paper presents a detailed analysis of errors in the diagnosis of bacteriologically negative pulmonary tuberculosis in a random sample of 560 patients out of all such patients registered in 1993. The false diagnosis was found in 63 patients i.e. in 11.3% of the sample. Among the 63 patients with false diagnosis of tuberculosis there were 15 cases with lung cancer, 15 cases with pneumonia and/or pleuritis, 15 cases with disease of circulatory system with abnormal radiological of the lungs, 8 cases with old post-tuberculosis changes in the lung considered as relapses, 4 cases of bronchiolitis obliterans with organizing pneumonia, 3 cases of sarcoidosis and 1 case of aspergillosis in a post-tb cavity. The most serious errors were those related to failure in diagnosing (or of too late diagnosis) of lung cancer. These failures comprised 2.7% of patients in the sample. The chance to detect a lung cancer in the sample was 2900 cases in 100,000 men and 2200 cases in 100,000 women. This chance was much higher than in general population--29x for men and 100x for women. The main source of errors was false interpretation of radiological examinations and neglect to utilise other diagnostic procedures like bronchoscopy, cytology or tomography examinations. As an outcome of the analysis authors present their recommendations for diagnostic procedures in the diagnosis of bacteriologically negative pulmonary tuberculosis.

Intraoperative ultrasound diagnosis (IOUSD) was made in several thoracoscopic interventions in 15 patients: diagnostic thoracoscopies (3) in patients with lymphogranulomatosis, carcinoid and peripheral lung cancer, enucleation and atypical resection of the lung (4) in patients with hamartochondromas, in excision of lung cyst (1), in removal of foreign body of the lung (1), in removal of celomic cysts (2) and in ablation of neurofibroma of the mediastinum (1), in atypical resection of the lung and enucleation of tuberculomas (2). Video thoracoscopy in combination with intraoperative ultrasound examination provides possibility for precisional diagnosis of focal disease of the lung and mediastinal organs, including local masses of small sizes, and is rather informative method of diagnosis. IOUSD allows to define the diagnosis more exactly and to determine the extent of pathological process, to prevent complications and locate intraparenchymal masses and foreign bodies in lung tissues, and thus enables to complete operation without thoracotomy.

A 61-year-old female presented with a unique case of moyamoya disease associated with pulmonary sarcoidosis. She was admitted for sudden onset of left temporalgia with episode of numbness on face, tongue, and upper extremity on the right side. The next morning, she had symptoms of Gerstmann syndrome and her ability to speak was disturbed. Her medical history included radical resection of lung cancer on the right side. She had no symptoms of pulmonary sarcoidosis. Neuroimaging showed an infarction in the left occipital lobe. Angiography showed occlusions of the bilateral internal carotid arteries at the supraclinoid portions. Subsequently, a left superficial temporal artery-middle cerebral artery anastomosis with encephalo-myo-synangiosis was performed. Ninety-three days after admission, she suddenly developed dyspnea which resulted in death 3 hours later. Autopsy findings showed typical epithelioid granulomas of sarcoid type in the lymph nodes of the peribronchus, lung, and liver. Thrombotic emboli were found in the bilateral pulmonary arteries, and marked fibrous intimal thickening in the bilateral internal carotid arteries. Immunological reaction with inflammatory events may cause pathological changes in patients with moyamoya disease or sarcoidosis. The co-incidence in this case suggests that some common inflammatory events may be involved in the pathogenesis of these diseases.

For more than 20 yrs it has been debated whether the systemic disease sarcoidosis predisposes to malignant neoplasms. The aim of this study was to examine the occurrence of cancer in Danish sarcoidosis patients observed for 9-30 yrs. The clinical data of 555 consecutive sarcoidosis patients were linked with the nationwide Danish Cancer Registry in a database, comparing the results with the expected incidence in the Danish population, adjusted for sex, age and calendar time. The sarcoidosis patients were diagnosed in two areas during the periods of 1960-1971 and 1970-1981, respectively, and followed until December 31, 1991. No excess of cancer was observed in sarcoidosis patients. A total number of 48 patients were observed with cancer (20 males and 28 females). Cancer occurred 1-29 yrs after sarcoidosis diagnosis (median 14 yrs) The observed versus expected (O/E) ratio was 1.16 (95% confidence interval (CI) 0.75-1.79) in males and 1.28 (95% CI 0.88-1.86) in females. No increased occurrence of lung cancer or malignant lymphoma (O/E ratios 0.23, 95% CI 0.00-1.25 and 1.25, 95% CI 0.02-6.95, respectively) was found. Neither age at diagnosis of sarcoidosis nor clinical sarcoidosis features were indicators of later occurrence of malignancy. The study could not confirm previous reports of an increased occurrence of malignant neoplasms in Danish sarcoidosis patients.

In order to determine the possible role of the cystic fibrosis transmembrane regulator (CFTR) gene in pulmonary diseases not due to cystic fibrosis, a complete screening of the CFTR gene was performed in 120 Italian patients with disseminated bronchiectasis of unknown cause (DBE), chronic bronchitis (CB), pulmonary emphysema (E), lung cancer (LC), sarcoidosis (S) and other forms of pulmonary disease. The 27 exons of the CFTR gene and their intronic flanking regions were analyzed by denaturing gradient gel electrophoresis and automatic sequencing. Mutations were detected in 11/23 DBE (P = 0.009), 7/25 E, 5/27 CB, 5/26 LC, 5/8 S (P = 0.013), 1/4 tuberculosis, and 1/5 pneumonia patients, and in 5/33 controls. Moreover, the IVS8-5T allele was detected in 6/25 E patients (P = 0.038). Four new mutations were identified: D651N, 2377C/T, E826K, and P1072L. These results confirm the involvement of the CFTR gene in disseminated bronchiectasis of unknown origin, and suggest a possible role for CFTR gene mutations in sarcoidosis, and for the 5T allele in pulmonary emphysema.

We describe an interesting case of adenocarcinoma of the lung accompanying sarcoidosis with diffuse myocardial involvement. A 69-year-old man had a tumor shadow on chest X-ray films of the right upper lung field. Bronchofiberscopy was performed in Jan. 1997. Because transbronchial biopsy specimens disclosed granuloma, the patient was treated with isoniazid, rifampicin, and streptomycin sulfate for tuberculosis, but did not show any improvement. In March 1997, the patient was examined by an ophthalmologist for blurred vision. He was given a diagnosis of uveitis and referred to us for evaluation because his serum ACE and lysozyme levels were elevated. Bronchofiberscopy was performed again, and a diagnosis of lung cancer accompanying sarcoidosis was made based on the findings of transbronchial biopsy and bronchoalveolar lavage. The disease progressed rapidly, and the patient died 47 days after admission. Autopsy disclosed sarcoid granulomas in cardiac muscle tissue and lung tissue. There have been very few reports on the co-existence of sarcoidosis and lung cancer, and the relationship between the two diseases is unclear.

A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.
