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.  相似文献

Three hundred and twenty autopsy cases of sarcoidosis in Japan were analyzed to determine the pathological changes in the early stage, the mode of progression in each organ and the changes in the final stage of the disease. The lung and the mediastinal lymph nodes were affected in most of the cases, while the lesions were limited to the lung and intrathoracic nodes in some of the cases. It was suspected that early changes developed in the lung and in the hilar, and then in the mediastinal lymph nodes. The progression of sarcoid granulomas in the lung was classified into three patterns: (i) probably of a disseminated hematogenous nature; (ii) of an interstitial lymphogenous nature; and (iii) of a local expansive nature. These three patterns were observed also in the heart. In the brain, perivascular granuloma formation was a prominent feature. In the other organs in which sarcoid lesions were not malignant nor disseminated and conglomerated, no interstitial patterns were observed. In chronic cases, repeated dissemination and particularly the interstitial spread of granulomatous changes led to a prominent interstitial fibrosis and dysfunction of the organs, finally resulting in death of the individual. In such long-standing cases, the mediastinal nodes deteriorated by hyalinous degeneration of the granulomas, and many active granulomas were formed in the intra-abdominal or body surface lymph nodes. These lymph nodes were likely to continue supplying sensitized lymphocytes to the whole body. A persistence of active change in the lymph nodes and the lymphogenous spread of granulomas in organs would appear to be key factors in the prognosis of sarcoidosis.  相似文献

We experienced a case of small cell carcinoma of the stomach in which chemotherapy had been markedly effective. A 54-year-old man was admitted to our hospital complaining of hematemesis. Gastric endoscopy showed a type 2 tumor at the lesser curvature of the cardia of the remnant stomach. Total gastrectomy, splenectomy and D2 lymph node dissection were performed. Histopathologically, the tumor was diagnosed as a small cell carcinoma with findings of t 2 n 1 in stage II, and conclusive curability was A. A month after the operation, CT-scan revealed multiple liver and lung metastases, so the patient was treated by combined chemotherapy with cisplatin and etoposide called PVP for three courses every four weeks for small cell lung cancer, which resulted in remarkable reduction of metastases (96% in the liver and 81% in the lung). This result suggests that PVP chemotherapy is effective in the treatment of small cell carcinoma of the stomach as well as the lung.  相似文献

We reported a case of epididymal sarcoidosis. The patient was a 13-year-old boy with a chief complaint of right scrotal mass. On physical examination, a firm, nontender 7 mm mass was palpable in the right hemiscrotum and appeared to involve the head of the epididymis. Ultrasonography showed a highly echogenic mass in the epididymis. A routine chest X-ray revealed lymphadenopathy of the mediastinum and reticular shadows in bilateral lung fields. Because the lesion might be confined to the epididymis, a partial epididymectomy was performed. The histopathologic specimen showed noncaseating granulomas consistent with sarcoidosis. Lung biopsies also revealed noncaseating granulomas. Subsequent pulmonary function studies revealed a mild obstructing ventiratory defect, therefore therapy was instituted with systemic steroids. There were no further recurrent scrotal masses. Although sarcoidosis is known to affect many organs, involvement of the genital system is relatively rare. Most of the patients with intrascrotal sarcoid lesions have an abnormal chest X-ray. We need to differentiate these lesions from advanced testicular cancer. This is the 5th case of intrascrotal sarcoidosis in Japanese literature.  相似文献

Cytokines play an important role in granuloma formation, but the extent that cytokine profiles are similar in different granulomatous diseases and whether differences in the histopathologic features of the granulomatous response results from differences in cytokine production have not been evaluated. To investigate these questions, we used RT-PCR to quantify the expression of mRNAs coding for 16 cytokines in granulomatous lymph nodes from patients with tuberculosis and sarcoidosis and from control tissues, and we sought correlations between the level of expression of these cytokines and the histopathologic features of the granulomas. Expression of mRNAs coding for a number of cytokines (IL-1beta, IFN-gamma, TNF-alpha, granulocyte-macrophage (GM)-CSF, IL-12 (p40), and lymphotoxin-beta) was increased in tuberculous and sarcoid granulomas compared with that of control tissues. All sarcoid granulomas were shown to express a Th1 pattern of cytokine mRNAs, while tuberculous lymph nodes expressed either a Th1 or a Th0 profile. GM-CSF and lymphotoxin-beta mRNAs were more abundant in sarcoid than in tuberculous granulomas, whereas IL-8 mRNA was strongly expressed only in tuberculous lymph nodes. Strong expression of GM-CSF, TNF-alpha, and IL-8 by granulomas was shown to be correlated, respectively, with the presence of florid granulomatous lesions, the absence of central necrosis, and the presence of neutrophil infiltration. These results demonstrate that the formation of tuberculous and sarcoid granulomas in humans is associated with the expression of characteristic cytokine profiles and indicate that the expression of certain cytokines is associated with the development of specific pathologic features in the resulting granulomas.  相似文献

Based on a clinical trial, in which patients with unresectable bronchogenic cancer were treated with a combination of vitamin A plus chemotherapy, or vitamin A plus radiotherapy, a study was initiated in which vitamin A alone was given for tumor treatment. 9 male patients with metastatic unresectable squamous cell carcinoma of the lung were treated with vitamin A palmitate or 13-cis vitamin A acid. Up to seven treatment courses were given during a period of 60 weeks. Through weekly evaluation of the patients' immune status, an immune potentiating effect of the vitamin A therapy could be demonstrated. An increase of lymphocyte blastogenesis response to PHA which is significant (p less than 0.001) compared with the pretreatment values, was found in all patients at the end of one vitamin A treatment course. Increased delayed cutaneous hypersensitivity reactions were observed also in all patients. The immune potentiating effects of vitamin A therapy, as well as the demonstrated direct effect on the tumor, introduces a wide range of combination therapies.  相似文献

A 35-year-old man affected with pulmonary sarcoidosis had a 12-year history of fatigue and pain in the limbs, with normal neurological examination, except for diffusely absent deep tendon reflexes. Muscle biopsy samples showed multiple noncaseating granulomas, most prominent around the intramuscular nerves, with predominance of CD4+ cells. Intramuscular nerve bundles surrounded by granulomas were immunolabelled with laminin alpha1, alpha2, beta1 and gamma1 chain, and collagen IV. Sural nerve biopsy samples were normal. This patient showed a unique histopathological pattern of sarcoid neuromyopathy characterized by distribution of granulomas or infiltrating cells around intramuscular nerve fibers. The clinical picture, restricted to nonspecific symptoms of fatigue and myalgia, and loss of deep tendon reflexes, correlated well with the selective localization of sarcoid lesions in contiguity with the intramuscular nerves. To our knowledge, this peculiar clinico-pathological correlation has not been reported previously.  相似文献

In order to assess the role of adhesion molecules in sarcoid lesions, we examined the expression of integrin families and extracellular matrix proteins by immunohistochemical techniques in sarcoid lymph nodes. Epithelioid cells exhibited intensive expression of ICAM-1, the alpha 5 and the beta 2 molecules. Lymphocytes exhibited intensive expression of ICAM-1, the alpha 4, the alpha 5 and beta 2 molecules. Laminin and type IV collagen were detected at basement membranes in vessels. Fibronectin was distributed within granulomas with a concentric pattern and around granulomas with a fibrillar pattern. Its distribution was well correspondence with the alpha 5 expression. These data suggest that integrin families might play an important role in granuloma formation and migration of lymphocytes into inflamed sarcoid lesions.  相似文献

A sixty-eight-year-old male patient was diagnosed as having inoperable advanced gastric cancer with liver and lung metastasis. The patient was treated by combined chemo-immunotherapy of MMC 10 mg/M, 5'-DFUR 800 mg/day and OK-432 5 KE/2 W. Six months after commencing chemotherapy, CT-scan and upper GI series revealed that metasized liver tumors and stomach lesion were remarkably decreased in size and no cancer cell was confirmed by endoscopic biopsy. Further, the metastatic lung tumor has disappeared on chest X-ray. The patient had been well without any evidence of tumor re-progression for over one year, but from July the liver tumor began to metastasize again and the patient eventually died of liver metastasis on Jan. 1, 1993.  相似文献

The accumulation of T cells and monocytes at sites of ongoing inflammation represents the earliest step in the series of events that lead to granuloma formation in sarcoidosis. In this study, we evaluated the pulmonary production of IFN-inducible protein 10 (IP-10), a CXC chemokine that stimulates the directional migration of activated T cells. Striking levels of IP-10 were demonstrated in the bronchoalveolar lavage (BAL) fluid of 24 patients with pulmonary sarcoidosis and lymphocytic alveolitis, as compared with patients with inactive disease or control subjects. A positive correlation was demonstrated between IP-10 levels and the number of sarcoid CD45R0+/CD4+ cells in the BAL. Immunochemistry, performed with an anti-human IP-10 polyclonal Ab in lymph nodes displaying prominent sarcoid granulomas, showed that cells bearing IP-10 were mainly epithelioid cells and CD68+ macrophages located inside granulomatous areas. Macrophages recovered from the BAL of sarcoid patients stained positive for IP-10 protein. Furthermore, alveolar macrophages isolated from sarcoid patients with T cell alveolitis and cultured for 24 h in presence of IFN-gamma secreted definite levels of IP-10 capable of inducing T cell chemiotaxis. Interestingly, alveolar lymphocytes recovered from patients with active sarcoidosis were CD4+ T cells expressing Th1 cytokines (IL-2 and IFN-gamma) and high levels of CXCR3. Taken together, these data suggest the potential role of IP-10 in regulating the migration and activation of T cells toward sites of sarcoid inflammatory process and the consequent granuloma formation.  相似文献

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.  相似文献

To improve our understanding of the role of extracellular matrix (ECM) proteins and integrins during the processes of granuloma formation in sarcoidosis, we examined the distribution of ECM proteins and the expression of integrins in sarcoid lymph nodes by immunohistochemical methods. We also examined the expression of transforming growth factor-beta1 (TGF-beta1), which is one of major regulators for synthesis of ECM proteins. Most ECM proteins were detected in the periphery of the granulomas in a concentric pattern, and fibronectin was diffusely detected from an early to a regressive stage. Compared with normal lymph nodes, most beta1-integrin subfamilies (alpha1, alpha4, alpha5 and alpha6) were more strongly expressed on lymphocytes around the granulomas. Epithelioid cells exhibited strong expression of the alpha5 molecule. Fibroblasts exhibited the expression of the alpha2 and alpha5 molecules surrounding ECM proteins. The alpha5beta1 molecule had a distribution similar to that of fibronectin. TGF-beta1 was detected in epithelioid cells throughout the various evolutional stages and its expression was especially marked in mature granulomas. Interaction of fibronectin and the alpha5beta1 molecule may have an important role in the process of formation of sarcoid granuloma. The expression of TGF-beta1 may be involved in the regression of sarcoid granuloma by initiating fibrosis and atrophy of epithelioid cells.  相似文献

BACKGROUND: Many cases of small cell lung cancer will occur in the elderly population but optimal management of the disease in this age group remains uncertain. AIMS: To evaluate treatment of small cell lung cancer in the elderly in Australia and to compare treatment received and outcomes with those of younger patients. To draw insights from these observations into the optimal management of small cell lung cancer in the elderly. METHODS: A retrospective review of treatment charts and case notes for 51 elderly patients and 102 younger patients was undertaken. RESULTS: Elderly patients had similar baseline parameters with respect to disease stage and performance status. Elderly patients were mostly treated uniformly with combination chemotherapy, but suffered more dose reductions than younger patients. Benefits of chemotherapy were seen even in patients with poor performance status. Despite the dose reductions, response rates and survival times for elderly patients were usually similar to younger patients. CONCLUSIONS: Combination chemotherapy is beneficial to elderly patients with small cell lung cancer. Optimal therapy for the elderly may be different from that for younger patients and should be defined through prospective randomised clinical trials.  相似文献

Hemorrhagic adrenal metastasis from lung cancer is extremely rare, although adrenal involvement is common in widely disseminated cancer. We report a case of massive adrenal hemorrhage secondary to metastasis of lung cancer. A 47-year-old female was treated by left upper lobectomy and mediastinal lymph node resection for an adenocarcinoma with intrapulmonary metastasis in the left upper lobe. Eight months later, she presented with right flank and back pain, and abdominal ultrasonography and computed tomography showed a right solitary adrenal tumor with massive hemorrhage. The tumor was not resectable and partially responded to chemotherapy. A massive adrenal hemorrhage, secondary to metastasis of lung cancer, presents with nonspecific clinical signs and symptoms. In lung cancer patients with an acute flank or back pain, hemorrhagic adrenal metastasis should be considered in the differential diagnosis.  相似文献

While resistance to chemotherapy is a major problem in lung cancer treatment, there is no useful predictor of treatment response. We thus designed this study to determine the utility of p53 and P-glycoprotein expression in predicting the response to chemotherapy in patients with primary lung cancer, retrospectively. We evaluated transbronchial biopsy (TBB) specimens from 60 patients with lung cancer, who were previously untreated. Formalin-fixed, paraffin-embedded TBB specimens were immunostained using anti-p53 antibody (DO-1) and anti-P-glycoprotein antibody (JSB-1). The positivity of p53 was 63%, and that of P-glycoprotein was 17%. No correlation was observed between p53 and P-glycoprotein immunostaining. Positivity of p53 correlated significantly (P = 0.004) with a lack of response to chemotherapy in non-small cell lung cancer (NSCLC), but not in small cell lung cancer (SCLC). In contrast, positivity of P-glycoprotein was correlated with chemotherapy resistance in SCLC (P = 0.003), but not in NSCLC. Multiple logistic regression analysis revealed that positive immunostaining for p53 was a significant risk factor for chemotherapy resistance in NSCLC. These results suggest that immunostaining of p53 and P-glycoprotein for TBB specimens may help to predict response to chemotherapy in NSCLC and SCLC, although the results should be confirmed in a larger, more homogeneous series.  相似文献

PURPOSE: We determined the need and sequence of retroperitoneal lymph node dissection and thoracotomy in patients with nonseminomatous testicular cancer, and with residual retroperitoneal and pulmonary masses after chemotherapy. MATERIALS AND METHODS: We studied 159 patients undergoing retroperitoneal lymph node dissection and a thoracotomy following cisplatin based induction chemotherapy for metastatic testicular nonseminomatous germ cell tumor. Several well-known predictors for residual histology (necrosis, mature teratoma and cancer) were evaluated. RESULTS: As expected, necrosis was found more often at retroperitoneal lymph node dissection if the primary tumor was negative for teratoma, the residual mass was small or the decrease in size was great. Contrary, neither residual mass size nor the decrease in size was predictive of the histological status of the residual lung lesion. Histological findings in the retroperitoneum and lung were strongly correlated, such that necrosis at retroperitoneal lymph node dissection was associated with an 89% probability of necrosis in the lung. CONCLUSIONS: Retroperitoneal lymph node dissection should be performed before thoracotomy is considered, since the histological status at dissection is a strong predictor of that at thoracotomy.  相似文献

BACKGROUND: Telomerase enzyme activity is not detected in most normal cells, a phenomenon believed to be associated with limitations on cellular proliferation. Since this activity is detected in nearly all human tumors, including non-small-cell lung cancers, it has been suggested that telomerase activation may be coupled to acquisition of the malignant phenotype. In this study, we determined whether telomerase activity was associated with tumor pathologic stage, tumor cell proliferation rates, and clinical outcome in a cohort of patients with resected non-small-cell lung cancer for whom long-term follow-up was available. METHODS: Primary tumor specimens from 99 patients treated with surgery alone and six patients treated with surgery after chemotherapy were analyzed. Telomerase activity was measured by means of a modified Telomeric Repeat Amplification Protocol (TRAP) assay. Southern blot analysis of terminal restriction fragments was used to evaluate telomere length. Immunohistochemical analysis of Ki-67, a proliferation-associated nuclear antigen, was used to assess tumor cell proliferation. RESULTS: Telomerase activity was detected in 84 of the 99 tumors treated with surgery alone; this activity was not detected in specimens of adjacent, benign lung tissue. Telomerase was detected in only three of six tumors resected after chemotherapy. For the surgery-alone group, statistically significant positive associations were found between the level of telomerase activity and tumor stage, lymph node metastasis, pathologic TNM (tumor-node-metastasis) stage, and Ki-67 immunostaining; a statistically significant inverse association was found between telomerase activity and patient age. No statistically significant differences in telomere length were found in relation telomerase activity or pathologic stage. Telomerase activity was not found to be associated with clinical outcome in a multivariate Cox proportional hazards analysis adjusted for tumor stage and lymph node status. CONCLUSIONS: High telomerase activity is detected frequently in primary non-small-cell lung cancers that exhibit high tumor cell proliferation rates and advanced pathologic stage.  相似文献

PURPOSE: In this study, the authors wanted to determine whether dipyridamole-modulated MIBI (dipyridamole-MIBI) could enhance the prediction of the response to chemotherapy in patients with small cell lung cancer. METHODS: Twenty-seven patients with biopsy-proved small cell lung cancer (25 men, 2 women; mean age, 61 +/- 7 years) underwent dipyridamole-MIBI SPECT 3 to 7 days before starting chemotherapy (80 mg/m2 etoposide and 80 mg/m2 cisplatin every 3 or 4 weeks for at least two cycles). Tomographic images before and after dipyridamole (0.84 mg/kg) were acquired 1 hour after injection of 370 (10 mCi) and 1,110 (30 mCi) MBq MIBI, respectively. The response to chemotherapy was grouped as specified as complete response (CR), partial (PR), no change (NC), or progressive disease (PD), according to the change in tumor size on chest roentgenography and CT. Patients showing CR and PR were classified as responders, and those who showed NC and PD were considered nonresponders. RESULTS: Among the 27 patients, 22 were responders (3 CR, 19 PR) and 5 were nonresponders (3 NC, 2 PD). The tumor-to-normal lung ratio (T:NL) of responders was significantly higher than that of nonresponders. The diagnostic accuracy of the T:NL ratio to differentiate responders and nonresponders was 33.3%, with a cutoff value of 2.5, which was significantly improved to 77.8% when an increased T:NL ratio after dipyridamole was assigned to a nonresponder. Furthermore, all patients with CR showed diminished T:NL ratios after dipyridamole, and all patients with NR showed an increased T:NL ratio after dipyridamole. CONCLUSION: Dipyridamole-MIBI SPECT could enhance the prediction of response to chemotherapy in patients with small cell lung cancer.  相似文献

OBJECTIVE: To analyze in vitro lymphocyte-mediated immune responses of horses with sarcoids against allogeneic sarcoid cells containing endogenous retrovirus but not expressing major histocompatibility complex antigens. DESIGN: Lymphocyte-mediated immune reactions were assessed by means of proliferative responses in mixed lymphocyte tumor cell culture (MLTC) assay and lymphocyte-mediated cytotoxicity against various equine target cells. ANIMALS: 12 horses with sarcoid tumors and 15 control horses. PROCEDURE: Blood lymphocytes were cocultured in MLTC with allogeneic sarcoid cells (Mc-1, BayMc-1), equine testis cells, or normal equine dermal fibroblasts. Lymphocytes were assayed for proliferative responses by [3H]thymidine uptake and for cytotoxicity against the same targets by 51Cr release assay. The lymphocyte populations were analyzed for some common surface markers. RESULTS: Lymphocytes from horses with sarcoids exerted an anamnestic proliferative response in MLTC against Mc-1 cells, but this procedure never generated cytotoxic lymphocytes. However, lymphocytes from all horses cultured in medium with 10% allogeneic serum only had selective. natural cytotoxicity against Mc-1 that was generated without DNA synthesis. Approximately 80% of the lymphocytes disappeared during culture; however the remaining population of small, viable lymphocytes indicated a decrease of CD4+ T lymphocytes, but numbers of T cells with receptors for Helix pomatia A hemagglutinin were unaffected. Few lymphocytes had Fc-receptors for IgG, were complement-reactive positive cells or were B cells expressing surface immunoglobulin. CONCLUSIONS: Results may indicate a natural defense system, which preferentially recognizes and lyses tumor cells that are deficient in surface expression of major histocompatibility complex antigens, without intervention of conventional T-cell receptors or antibodies.  相似文献
