An incidence of 0.4% to 1.3% has been reported in literature. The primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. In this report, two cases of pulmonary metastasis to the breast were presented. A 40-year-old female manifested a right breast mass of 2-month duration. After physical examination was performed, a poorly defined mass was noted in the upper outer quadrant of the right breast. Another 49-year-old female manifested right breast mass of 5-day duration. A poorly defined mass was noted in the lower inner quadrant of the right breast. Mammography results also revealed breast cancer. The patients underwent local excision. After histological and immunohistochemical analyses were conducted, a primary lung carcinoma that metastasized to the breast was diagnosed. An accurate differentiation of metastasis to the breast from primary breast cancer is very important because the treatment and prognosis of the two differ significantly.展开更多

Methods: Expression of Ezrin and survivin were detected and analyzed by Envision method of immu- nohistochemical staining in 86 NSCLC. Results: The strong expression rate of Ezrin in NSCLC was 60.5% and significantly correlated with lymph node metastasis (P < 0.05), but no associated with gender, histologic subtype, TNM stages, differen- tiation and smoking. Meanwhile, the positive expression rate of survivin in NSCLC was 65.1% and significantly correlated with TNM stages and lymph node metastasis (P < 0.05), but no associated with gender, histologic subtype, differentiation and smoking. And expression of Ezrin and survivin were positively correlated in NSCLC (r = 0.384). Conclusion: Ezrin and survivin may play synergetic roles in the process of carcinogenesis of NSCLC, and their expression may be significantly associated with NSCLC metastasis. Detection of Ezrin and survivin may be valuable for diagnosing lung cancer metastasis and providing evidence for clinical treatment.展开更多

Of 88 patients tested, 48(54.5%) showed positive staining. The Positive staining rate was higher in adenocarcinoma (28/42, 66.7%) than in squamous cell carcinoma (20/46, 43.5%; P<0.05).Higher incidence of positve staining wasalso found in squamous cell carcinomas without hilar or mediastinal lymph node metastasis (16/27, 59.3%) than in those with hilar or mediastinal lymph node involvement (4/19, 21.1 %;P<0.05). NDP kinase/nm23 was equally expressed in adeno-carcinoma, irrespective of lymph node status. In both cell types of carcinoma, expression of NDP kinase/nm23 was not correlated with tumor cell differentiation, nor was it correlated with the P-TNM staging. Our results suggest that NDP kinase/nm23 may play different roles in the pathogenesis and metastasis of human pulmonary squamous cell carcinoma and adenocarcinoma. Its expression levels are inversely correlated with lymph node metastasis of squamous cell carcinoma of the lung.展开更多

Twenty-eight patients had well-differentiated, 22 had moderately differentiated and 30 had poorly differentiated adenocarcinoma. Forty-five patients and 35 patients had lymph node metastasis. Forty-five patients were of Dukes A to B stage, and 35 were of C to D stage. Another 22 paraffi n-embedded tissue blocks of normal colorectal epithelium (>5 cm away from the edge of the tumor) were selected as the control group. All patients with colorectal cancer were treated surgically and diagnosed histologically, without preoperative chemotherapy or radiotherapy. The immunohistochemistry was used to detect the ezrin expression in paraffin-embedded normal colorectal mucosa tissues and colorectal cancer tissue samples.RESULTS: Ezrin expression in colorectal cancer was significantly higher than in normal colorectal mucosa (75.00% vs 9.09%, P<0.01), and there was a close relationship between ezrin expression and the degree of tumor differentiation, lymph node metastasis and Dukes stage (88.46% vs 50.00%, P<0.01; 94.28% vs 51.11%, P<0.01; 94.28% vs 51.11%, P<0.01).CONCLUSION: Ezrin expression is obviously higher in colorectal cancer tissues than in normal colorectal mucosa tissues, and the high level of ezrin expression is closely related to the colorectal cancer invasion and metastasis process.展开更多

Methods： The expressions of Livin and Smac proteins were detected in 89 NSCLC tissue samples and 25 normal lung tissue samples by immunohistochemical technique. Results： The positive expression rates of Livin and Smac proteins in NSCLC tissues were 53.9%, and 58.4% respectively, higher than that in normal lung tissues（P〈0.01）. Livin protein expression correlated with Smac protein significantly（Χ^2=1 8.451, P=0.000, r=0.455）. The expression level of Livin protein was closely related to lymph node metastasis, TNM stage and histological type （P〈0.05）, but not to sex, age, differentiation grade （P〉0.05）. The expression level of Smac protein was closely related to lymph node metastasis, TNM stage （P〈0.01）, but not to sex, age, histological types （P〉0.05）. Kaplan-Meier analysis revealed a significant impact on survival by Livin protein in NSCLC （P〈0.01）, but not by Smac protein （P〉0.05）. Conclusion： Overexpression of Livin protein may play a promoting role in the occurrence and progression of NSCLC. Moreover, it may bring an adverse effect on patients＇ prognosis. Although overexpression of Smac protein affects the occurrence and progression of NSCLC, it has no relationship with the prognosis. Livin protein may be helpful to evaluate the progression of NSCLC, and to predict the prognosis.展开更多

In the present study, we report the case of a 78-year-old male who was admitted to the emergency department with acute bleeding of the digestive tract. During evaluation, he was found to have lung adenocarcinoma metastasis in the small bowel leading to hemorrhage. A jejunum wedge resection was carried out and bleeding was controlled. However, 2 months after the operation, the patient died from severe pulmonary infection. We also review the published literature of primary lung cancer with gastrointestinal metastasis.展开更多
