1.Progress and prospect on the clinicopathological study of small hepatocellular carcinoma
Chinese Journal of Hepatobiliary Surgery 2011;17(5):353-356
Early detection and treatment of hepatocellular carcinoma (HCC) is one of the most direct and effective ways to improve the long-term outcome of patients with HCC. The comparative study on clinicopathological characteristics of surgically resected micro HCC (≤1 cm), small HCC(≤3 cm), middle HCC (3-5 cm), and large HCC (>5 cm) showed that ≤3 cm small HCC had the features of DNA diploidy, well differentiation, relatively slow growth, encapsulation, rare long-distance metastatic foci and thrombosis, easy to be radically resected and long-term postoperative survival. It is suggested that HCC growing to about ≤3 cm is an important growth phase when the change of pathobiological characteristics of HCC from a relatively benign to a more malignant behavior would occur. This is also the important time to carry out radical treatment to get better results. Therefore,further research on the early diagnosis and treatment as well as the pathobiological features of small HCC ≤3 cm should be undertaken as one of the key clinical and pathological studies in the future.
2.Some thoughts on the development of surgical pathology for hepatobiliary tumors
Chinese Journal of Hepatobiliary Surgery 2012;18(9):649-651
Surgical-oncological pathology is one of the most important supporting discipline for hepatobiliary surgery.With rapid development in modern hepatobiliary surgery,the traditional model of morphological diagnosis can no longer meet the needs of oncological surgery.To improve the level of pathological diagnosis, better understand clinical concerns,update the mode of pathological diagnosis,introduce new technologies,expand the connotations of pathological diagnosis,provide a new indexing system for clinical treatment programs,and focus on interdisciplinary collaborative research are the most important issues in the development of surgical pathology for hepatobiliary tumors.
3.Detection of circulating tumor cells and its clinical application
Cancer Research and Clinic 2016;28(12):851-854
Circulating tumor cell (CTC) is a kind of malignant tumor cells shed from the primary tumor into the circulation caused by spontaneity or surgical operation and puncture. With the development of CTC analysis recently, the detection methods have been gradually diversified. As a new biomarker, CTC plays a significant role in the diagnosis, therapeutic effect monitoring and prognosis of tumors. This paper mainly introduces the enrichment and analysis technology of CTC, and explore the relationship between CTC and tumors.
4.Stereotactic radiation therapy in the era of precision medicine for cancer.
Chinese Journal of Applied Physiology 2015;31(6):491-497
Unlike conventional radiation therapy, stereotactic radiation therapy (SRT) is an emerging tumor-ablative radiation technology with a high-dose delivery to targets while dramatically sparing adjacent normal tissues. The strengths of SRT involve noninvasive and short-course treatment, high rates of tumor local control with a low risk of side effects. Although the scientific concepts of radiobiology fail to be totally understood currently, SRT has shown its potential and advantages against various tumors, especially for those adjacent to less tolerable normal organs (spinal cord, optic nerve, bowels, etc.). Nowadays, the clinical efficacy of SRT has been widely confirmed in certain patients, especially for those medically inoperable, unwilling to undergo surgery, medicine ineffective with tumor progression. Moreover, SRT could be properly used as palliative treatment aiming at relieving local symptoms and pain, and eventually achieving a potential survival benefit of several months. However, the weaknesses of SRT relate to inevitable radiation-induced toxicities as well as the inaccessibility of prophylactic irradiation. In general, one flaw cannot obscure the splendor of the jade. The emergence and development of SRT has opened the new era of precision radiation therapy, and SRT will probably step gloriously onto the remarkable stage for precision medicine.

To study the immunopathological characteristics and differential diagnosis of hepatic angiomyolipoma(AML).Methods:Thirty-six surgically resected hepatic AML were investigated clinicopathologically and immunohistochemically with 10 antibodies.Results:Hepatic AML occurred in 21 females and 15 males,with the mean age of 41.6 years(26-60 years old).The patients with AML often had no special symptoms even had large space-occupying lesions in the liver.The diameter of AML was 2.5 cm to 14 cm(mean 6.8 cm).Histologically,AML was composed of varying heterogeneous mixture of 3 tissue components:blood vessels,smooth muscle and adipose cells.Extramedullary hemopoiesis sometimes existed.According to tissue components,AML was subcategorized into mixed type(19.4%,n=7),lipomatous type(11.1%,n=4),myomatous type(66.7%,n=24),and angiomatous type(2.8%,n=1).The epithelioid smooth muscle cells were sensitive to HMB-45(100%),SMA(100%),and CD117(66.7%) staining.Conclusion:Hepatic AML often contains smooth muscle elements,which have varied morphological features and should be carefully differentiated from hepatocellular carcinoma,mesenchymal hamartoma,and tumors with rich fat or blood vessels.Immunohistochemical staining with HMB-45 and SMA are the best available markers for the diagnosis of hepatic AML.
