Hemorrhage from carcinoma of the lung   总被引:3,自引:0,他引:3  
R R Miller  D H McGregor 《Cancer》1980,46(1):200-205
During a retrospective analysis of 877 cases of lung cancer, we explored the relationships between cell type, site, cavitation, varying degrees of hemoptysis, and radiation therapy. Massive terminal hemoptysis (29 cases) was found to be significantly associated with cavitated (P less than 0.0001 squamous cell carcinoma (P = 0.0002), ARISING IN EITHER THE RIGHT OR LEFT MAIN BRONCHI (P less than 0.0001). Lesser, nonlethal degrees of hemoptysis (140 cases) were not cell-type associated, occurring in approximately 15% of cases of all major tumor types. Radiotherapy, although employed more frequently in the massive-hemoptysis population, did not appear to be causally related to hemoptysis of any degree. An interesting case, which provoked the above study, is described: a patient with bronchogenic squamous cell carcinoma and terminal hemoptysis due to a tumor fistula between the primary lesion and the left atrial chamber. The forms of cardiac involvement in lung cancer are discussed.  相似文献

PURPOSE: This study was performed to evaluate the clinical outcomes of three-dimensional (3D) conformal hypofractionated single high-dose radiotherapy for one or two lung tumors using a stereotactic body frame. MATERIALS AND METHODS: Forty patients who were treated between July 1998 and November 2000 and were followed for >10 months were included in this study. Of the 40 patients, 31 had primary lung cancer and 9 had metastatic lung cancer. The primary lung cancer was staged as T1N0M0, T2N0M0, and T3N0M0 in 19, 8, and 4 patients, respectively. The primary sites of metastatic lung cancer were the colon in 4, tongue in 2, and osteosarcoma, lung cancer, and hepatocellular carcinoma in 1 each. 3D treatment planning was performed to maintain the target dose homogeneity within 15% and to decrease the irradiated lung volume from >20 Gy to <25%. All patients were irradiated using a stereotactic body frame and received 4 times 10-12 Gy single high-dose radiation at the isocenter during a period of 5-13 days (median 12). RESULTS: The initial 3 patients received 40, and the remaining 37 patients received 48 Gy after dose escalation. Of the 33 tumors followed >6 months, 6 tumors (18%) disappeared completely after treatment. Twenty-five tumors (76%) decreased in size by 30% or more after treatment. Therefore, 31 tumors (94%) showed a local response. During the follow-up of 4-37 months (median 19), no pulmonary complications greater than National Cancer Institute-Common Toxicity Criteria Grade 2 were noted. Of the 16 patients with histologically confirmed T1N0M0 primary lung cancer who received 48 Gy, all tumors were locally controlled during the follow-up of 6-36 months (median = 19). In 9 tumors with lung metastases that were irradiated with 48 Gy in total, 2 tumors did not show a local response. Finally, 3 tumors (33%) with lung metastases relapsed locally at 6-12 months (median 7) after treatment during the follow-up of 3-29 months (median 18). CONCLUSION: 3D conformal hypofractionated single high-dose radiotherapy of 48 Gy in 4 fractions using a stereotactic body frame was useful for the treatment of lung tumors.  相似文献

BACKGROUND. Although lung cancer frequently spreads to the heart, details of cardiac metastases of lung cancer have not been fully discussed. The authors attempted to elucidate the relationship between the mechanisms of cardiac metastasis and a variety of clinical manifestations caused by cardiac metastasis. METHODS. Clinical and autopsy records were reviewed in 74 autopsied cases of lung cancer. In cases with cardiac metastasis, the metastatic pathways to the heart were determined by the macroscopic examinations, and the relationship between the metastatic pathways and the clinical manifestations were studied. RESULTS. Metastases to the pericardium or heart were seen in 23 cases (31%). A lymphatic metastatic pathway was detected in 18 cases (hilar lymphatic routing in 12 cases, and mediastinal lymphatic routing in 6 cases), and a hematogenous metastatic pathway was detected in 5 cases. Malignant pericardial effusion was documented in 15 of 23 cases. The metastatic pathway in 14 of 15 cases was lymphatic (hilar lymphatic routing in 10 cases, and mediastinal lymphatic routing in 4 cases). Patients showing lymphatic metastasis had higher incidence of malignant pericardial effusion than those with hematogenous metastasis (P less than 0.05). Of 23 cases of cardiac metastasis, myocardial infarction was found in 1 case, resulting from the compression of the coronary arteries by the tumor. Concurrent supraventricular arrhythmias were recorded in eight cases with cardiac metastasis. Patients with cardiac metastasis had higher incidence of arrhythmia than those without cardiac metastasis (P less than 0.05). In cases of cardiac metastasis, patients with arrhythmia were older (P less than 0.01) than those without arrhythmia. CONCLUSIONS. The authors concluded that the hilar lymphatic pathway is essential for early development of malignant pericardial effusion in lung cancer and that aging and cardiac metastasis may be responsible for arrhythmia in patients with lung cancer.  相似文献

To investigate whether high serum levels of carotenoids, tocopherols, and folic acid decrease risk of lung cancer in Japanese, we conducted a case-control study nested in the Japan Collaborative Cohort (JACC) Study. A total of 39 140 subjects provided serum samples at baseline between 1988 and 1990. We identified 147 cases (113 males and 34 females) of death from lung cancer during an 8-year follow-up. Of the subjects who survived to the end of this follow-up, 311 controls (237 males and 74 females) were selected, matched to each case of lung cancer death for gender, age and participating institution. We measured serum levels of antioxidants in cases of lung cancer death and controls. Odds ratios (ORs) for lung cancer death were estimated using conditional logistic models. The risk of lung cancer death for the highest quartile of serum α-carotene, β-carotene, lycopene, β-cryptoxanthin, and canthaxanthin was significantly or marginally significantly lower than for the lowest quartile: the ORs, adjusted for smoking and other covariates, were 0.35 (95% confidence interval (Cl), 0.14–0.88), 0.21 (0.08–0.58), 0.46 (0.21–1.04), 0.44 (0.17–1.16) and 0.37 (0.15–0.91), respectively. The ORs for the highest serum levels of zeaxanthin/lutein and folic acid tended to be low, but the differences were not statistically significant. Serum total cholesterol was also inversely related to risk of lung cancer death: the OR for the highest vs. the lowest quartile was 0.39 (95% Cl, 0.19–0.79). Higher serum levels of carotenoids such as α- and β-carotenes may play a role in preventing death from lung cancer among Japanese. (Cancer Sci 2003; 94: 57–63)  相似文献

Polymorphism of glutathione S-transferase omega gene and risk of cancer   总被引:4,自引:0,他引:4  
Polymorphic glutathione S-transferase (GST) genes causing variations in enzyme activity may influence individual susceptibility to cancer. Though polymorphisms have been reported in GSTO1 and GSTO2, their predisposition to cancer risk has not yet been explored. In this case control study, 28 cases of hepatocellular carcinoma, 30 cases of cholangiocarcinoma, 31 cases of colorectal cancer, 30 cases of breast cancer and 98 controls were compared for frequencies of GSTO1 and GSTO2 genotypes. The statistical analysis provided the support for the difference in genotypic distribution for GSTO1*A140D between hepatocellular carcinoma (OR 23.83, CI 95%: 5.07-127), cholangiocarcinoma (OR 8.5, CI 95%: 2.07-37.85), breast cancer (OR 3.71, CI 95%: 1.09-13.02) and control. With regards to GSTO2*N140D polymorphism, there was no difference in genotypic distribution between all the types of cancer and control. The study suggests that GSTO1*A140D polymorphism could play an important role as a risk factor for the development of hepatocellular carcinoma, cholangiocarcinoma and breast cancer.  相似文献
