  • Research Progress of Sentinel Lymph Node Biopsy in the Surgery of Thyroid Carcinoma

    ObjectiveTo summarize the research progress of sentinel lymph node biopsy (SLNB) in the surgery of thyroid carcinoma in recent years. MethodsLiteratures about the recent studies on categories of SLNB and the neck lymph node dissection conducted by SLNB in the surgery of thyroid carcinoma were reviewed following the results searched from PubMed and CNKI data base. ResultsSLNB has a high detection rate and it is of great significance to detect the occult metastatic lymph nodes and guide the neck lymph node dissection during operation. ConclusionThe SLNB, with its high accuracy rate on the detection of occult metastatic lymph nodes, guides neck lymph node dissection during operation in order that it can maximize the benefits of patients.

  • Clinical Application Research of Fluorescent Tracer Technique in cN0 Papillary Thyroid Carcinoma

    ObjectiveTo explore the value of fluorescence tracer technique in sentinel lymph node (SLN) orientation of cN0 papillary thyroid cancer. MethodsThe total clinical data of 40 cT1-3N0M0 thyroid cancer patients admitted from January 2015 to January 2016 in our hospital were collected, and the SLN with indocyanine green (ICG) as fluorescent trace agent were observed and detected, and the effect of ICG detecting SLN and the guide role of SLNB on the dissection of the central area of neck lymph nodes by intraoperative frozen biopsy pathology and postoperative paraffin pathology were analyzed. ResultsA total of 40 thyroid cancer patients were treated by SLNB and then conducted by the dissection of the central area of neck lymph nodes, and 37 cases detected SLN, so the detection rate was 92.5% (37/40). And a total of 98 SLNs were detected, 1-5 for each case, average of 2.65/case. Intraoperative frozen pathological detected 28 cases of patients with metastases in SLN, and 9 patients without metastasis, including 1 case with postoperative pathology detecting micrometastasis in SLN and other 8 cases without metastasis in the central area of neck lymph nodes. Three cases who were not detected the SLN showed no metastases in final postoperative paraffin pathology. The SLNB of ICG fluorescent tracer was with a sensitivity of 96.6% (28/29), false-negative rate of 3.45% (1/29). ConclusionThe fluorescent tracer technique can guide the dissection of the central of neck lymph node of cN0 thyroid cancer patients accurately with a high detection rate and advantages of high sensitivity in detecting the SLN of thyroid cancer.

  • Expression of microRNA-21 in Gastric Cancer of Different Tumor Stages

    ObjectiveTo quantitate expression of microRNA-21 (miRNA-21) in gastric cancer of different tumor stages and discuss its clinical value. Method The relative expressions of miRNA-21 were quantitated in the cancer tissues, corresponding normal gastric tissues adjacent to gastric cancer, and serums of 50 gastric cancer patients received opera-tion and confirmed gastric cancer by pathology and the serums of nongastric cancer patients in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and its Chongming Branch from January 2015 to January 2016 by real time quantitative PCR. ResultsThe relative expression level of miRNA-21 in the gastric cancer tissues was significantly higher than that in the normal gastric tissues adjacent to gastric cancer. Among the TNM stageⅠ, Ⅱ, Ⅲ of gastric cancer patients, the relative expression levels of miRNA-21 in the cancer tissues were 2.17 (1.48-2.90), 4.08 (2.30-4.86), 8.64 (5.82-18.20), respectively and the differences among these three stages were statistically significant (P<0.05). The relative expression level of the serum miRNA-21 in the gastric cancer patients was significantly higher than that in the nongastric cancer patients, which in the serums for stageⅠ, Ⅱ, and Ⅲpatients were 31.00 (24.60-37.15), 39.10 (28.90-39.80), 44.15 (38.95-56.68), respectively and the differences among three stages were statistically significant (P<0.05). The relative expression level of miRNA-21 in the serums and cancer tissues had a positive correlation (r=0.86, P<0.05). ConclusionMiRNA-21 appears to have a potential association with TNM stage of gastric cancer, which cautiously suggests that it might be a potential indicator for prediction of preoperative TNM stage of gastric cancer.
