1.Current application of sentinel lymph node biopsy in cutaneous malignant melanoma
Chinese Journal of Clinical Oncology 2014;(12):810-813
Sentinel lymph node biopsy has a very important function in the accurate staging, diagnosis, and treatment of malig-nant melanoma. The operational technique of sentinel lymph node biopsy (SLNB) has been basically mature, but its indications remain unclear, especially for thin melanomas. Adequate evidence to show that SLNB combined with a complete lymph node dissection can prolong the survival of patients with metastasis is unavailable. Given the low incidence of malignant melanoma in the country, the use of SLNB has not been extensively investigated in China and the relevant methods are outdated. This review summarizes the current ap-plication of SLNB in cutaneous malignant melanoma by analyzing related studies conducted in recent years.
2.Present perceptions and trends of surgical margin in soft tissue sarcoma in limbs and trunk
Chinese Journal of Clinical Oncology 2017;44(1):2-6
Limb salvage surgery with comprehensive treatment is the standard care for soft tissue sarcoma in the limbs and trunk. Marginal status is a key factor in determining the quality of surgical treatment, as well as in guiding the selection of adjuvant therapies. The goal of surgery is to obtain an appropriately negative margin, although no consensus exists regarding the adequate thickness of normal tissue cuff. With the development of auxiliary treatments, surgery for soft tissue sarcoma is becoming less extensive. Marginal resection combined with adjuvant therapies may be necessary to preserve limb functions when the tumor is close to critical vessels, nerves, or bones. When preparing the preoperative plans, additional considerations should include histologic type, location, presence of barriers, and response to adjuvant therapies.

Objective To study the clinical features and treatment of multiple schwannomas (neurilemmomas). Methods 9 patients with multiple schwannomas treated with surgery from 1975 to 1999 were reviewed retrospectively. Results In 7 of the 9 cases of schwannomas, the number of tumor lesions was seen more than that diagnosed preoperatively. All the patients had surgical resection; 5 had enucleation and 4 had tumors excised with the invovled nerve. Recurrence occured in 4 patients. Conclusion Because of the difficulty in predetermination of the exact lesional number, thoroughly preoperative examination including MRI is nessesary. Enucleation is recommended to those tumors involving important nerves. There is a high rate of recurrence.

Sarcomas are tumors of mesenchymal origin that account for approximately 1%of human cancers. There are at least 60 dif-ferent subtypes of soft tissue sarcoma (STS). However, most tumor types are highly malignant tumors that lack an optimal therapeutic agent. Although gastrointestinal stromal tumor (GIST) responds well to imatinib, other types of STSs remain challenging because of their heterogeneous genetic and clinical features and poor prognosis. In recent years, the field of molecular targeted therapy has pro-gressed rapidly. Patients with advanced disease can receive individualized treatment to improve their quality of life. This review focus-es on the targeted therapies that have been evaluated for advanced non-GIST STS. Other promising novel therapeutic agents that are currently in the early phases of investigation are also presented.
