Methods: Forty patients with stage ⅢA NSCLC underwent two cycles of neoadjuvant chemotherapy with mitomycin, vindosine, and cisplatin followed by surgery. Histopathologic response in resection of the tumor was examined after surgery. Tumor regression was classified as grade Ⅳ, grade Ⅲ, grade Ⅱ, and grade Ⅰ according to the extent of tumor necrosis and the extent of the vital tumor tissues. The tumor regression grading was correlated with the survival time of the patients. Results: After two cycles of chemotherapy, 19 (47.5%) of 40 patients had objective response (2 complete and 17 partial response). In 40 resected tumor specimens, 2 (5%) were classified as regression grade Ⅳ, 16 (40%) as regression grade Ⅲ, 18 (45%) as regression gradeⅡ, and 4 (10%) as regression grade Ⅰ. The rate of complete surgical resection was significantly higher in patients with tumor regression grade Ⅲ-Ⅳ (〈10% vital tumor tissue)(P〈0.05). The median survival time in patients classified as having tumor regression grade Ⅲ-Ⅳ was significantly longer than that in patients who had regression grade Ⅰ-Ⅱ (P〈0.05). The 3-year survival rate in patients with regression grade Ⅲ-Ⅳ was markedly higher than that in patients who had regression grade Ⅰ-Ⅱ (P〈0.05). Conclusion: The extent of tumor regression induced by neoadjuvant chemotherapy is a critical issue for successful therapeutic approach in patients with stage ⅢA NSCLC. In resected specimens of tumors after chemotherapy, the presence of marked tumor regression (regression grade Ⅲ-Ⅳ) is predictive for superior survival time.展开更多

Chest computed tomography showed multiple flakes in his lungs, nodules shadow, right pleural effusion with right pulmonary atelectasis The pathological specimens obtained by thoracic surgery revealed pulmonary angiosarcoma. Primary pulmonary angiosarcoma is a rare malignant tumor and is lack of typical clinical symptoms and imaging features, diagnosis mainly depend on histopathologic features and immunohistochemical analysis. There is no effective therapy for pulmonary vascular sarcoma. Integrated treatment can may extend the survival time of patients.展开更多

It appears as a histopathologic benign smooth muscle tumors, distant from the uterus. It is hormone dependent and progresses slowly. Operation is the main clinical treatment. The article was reported one case who was a thirty-eight years old female. She was found to have bilateral lung nodules after hysterectomy of uterine leiomyoma seven years ago. An open lung biopsy revealed that the nodules consist of proliferating smooth muscle cells with a histopathologic feature which was similar to her uterus leiomyoma. Positive staining of estrogen and progesterone receptors were detected, which proved the turner originate from utedne. The patient did not accept operation, chemotherapy, radiotherapy or other treatment. We still follow up the development of the case.展开更多
