The purpose of our study was to show if there is any correlation between the location of the primary cancer site in the lungs, and the appearance of metastases in the spleen. 1,998 patients with confirmed lung cancer were analyzed. In 22 out of 22 cases, splenic lesions were detected by both, computer tomography (CT) and ultrasound (US) in all 22 of them. All patients with splenic lesions detected by the US underwent US-guided biopsy. Among these patients, metastases to the spleen were histopathologically confirmed in all 22 cases. 18 metastases in the spleen originated from left lung tumors, 3 from right lung tumor. In the 1 case remaining, a pattern of benign lesion was confirmed. The authors came to the conclusion that lung cancer metastases detected in the spleen originate mainly from the left lung cancer which can be caused by higher blood flow to the left lung as compared to the right lung.

Diagnosis of Small Cell Lung Cancer through the Biopsy of Spleen Metastases： Rapid Communication

引用

材料科学与工程（中英文B版） 2014年第12期4卷 385-387页

Metastases of lung cancer to the spleen are a great rarity and described sporadically. The authors describe the case of the left lung cancer in which the histopathological diagnosis was made only on the base of the biopsy material taken from the metastatic lesion in the spleen. Interestingly, the location of the primary cancer site made it impossible to obtain the specimens and only a single distant metastatic lesion was found in the spleen. The case presented above is an example that metastasis can occur in every organ, sometimes can be isolated in the least probable organs, and when such organ is available for biopsy, it can be useful for pathological diagnosis.

Multi-Year Observation of Lung Cancer Metastases to the Adrenal Glands

材料科学与工程（中英文B版） 2013年第6期3卷 393-399页

The purpose of our study was to show if there is any correlation between the location of the primary cancer site in the lungs and the appearance of metastases in the adrenal gland. 2,340 patients with confirmed lung cancer were analyzed. The study group of 2,340 patients was divided into two subgroups: 1,998 patients were diagnosed with lung cancer located only in one lung, and 342 with disseminated lung cancer. Among the group of 1,998 patients, in 218 cases, pathological lesions in the adrenal glands were detected using computer tomography (CT) or magnetic resonance (MR). In 161 out of 218 cases, suprarenal lesions were detected by ultrasound (US). All patients with suprarenal lesions detected by US (161 cases in total ) underwent US-guided biopsy. Among these patients, metastases to the adrenal glands were histopathologically confirmed in 91 cases. In 70 cases, the histopathological reporting confirmed benign lesions. Altogether there were 64 adrenal metastases originated from the left lung cancer and 32 metastases from the right lung cancer. In 342 patients with disseminated cancer, four of them had confirmed metastases in both adrenal glands; seven patients had a metastatic lesion in the left and three in the right adrenal gland. Among this group, metastases to other organs such as the liver, bones, central nervous system and mediastinal lymph nodes were also detected. The authors came to the conclusion that the higher occurrence rate of adrenal metastases from the left lung carcinoma as compared to the right lung carcinoma is associated with higher blood flow in the left lung.

Innovative method of Transthoracic Lung Cancer Biopsy of Parietal Lung Tumors under US Guidance after CT Pre-biopsy Planning as an Alternative to CT- Guided Biopsy

引用

材料科学与工程（中英文B版） 2014年第12期4卷 376-384页

The authors compared their earlier results of the tumor biopsies performed under computer tomography (CT) guidance against the results of their recently modified-combined method of visualization and measurement of lung tumor parameters by CT imaging followed by US guided biopsy. In 238 (6.36%) of 3,745 patients in CT examination, the lung tumor was located peripherally, and obtaining histopathological confirmation was crucial to start the proper treatment. The patients were divided into two groups, the division was based on the biopsy method. Within the first group in 118 patients, parietal lung tumor was confirmed and CT guided biopsy was performed. Within the second group, parietal lung tumor was confirmed in 120 patients and combined method of CT pre- biopsy planning and US guided biopsy were used. Pre-biopsy planning was performed using CT, measurements such as depth and distance of the tumor were made, obtained data were then saved on CT image and patient"s skin was marked. Then obtained results were analyzed using test for two proportions. The analysis of the results confirmed the higher efficacy of the combined method taking into account the number of complications (p < 0.01) and diagnostic histopathological results (p < 0.001). Suggested innovative method, involving both CT pre-biopsy planning and US guided biopsy, allows to analyze simultaneously static CT and dynamic US images and it is considered to be an easy and effective method comparing to relying on static in nature CT images only. Our method is related to a lower complication risk rate.
