From 1984 to 1993, 49 cases with varioussoft tissue defects around the knee were treated with pedicled calf myocutaneous flap, lateral sural cutaneous artery island skin flap, saphenous neurovascularskin flap and fasciocutaneous flap. The postoperation results were sucessful in 47 cases, and failure 2 cases, in one case with flap infection and theother with scar formation surrounding the knee. Both the failure cases were cured with split skin graft. The patient were followed up for an average of three and a halfyears, the knee function was almost completely regained, and the blood supply of the flaps, the elasticity and colour of the flaps were similiar to that of the normal skin, without being cumbersome. The sensation of the saphenous neurovascular flaps and the lateral suralcutaneous artery island flaps was preserved, except partial numbness was presented at the distal part of the flaps. Operative indications and selection of cases were discussed.
Objective To evaluate the potential of specific mRNA marker keratin 19(K19) to detect micrometastasis by reverse transcriptase polymerase chain reaction (RT-PCR) .Methods One hundred and ninty four regional lymph nodes harvested from 6 cases of benign diseases, 4 cases of breast carcinoma, 5 cases of gastric carcinoma and 12 cases of colorectal carcinoma patients were examined by conventional pathology and amplifying tissue specific K19 mRNA by RT-PCR separately, then the two methods were compared with each other. Results None of the 34 lymph nodes which were pathological metastasis-negative from benign diseases expressed K19 mRNA by RT-PCR, all of the 28 regional lymph nodes which were pathological metastasis-positive from malignant cases showed trains of K19 mRNA by RT-PCR. Of the 132 lymph nodes which were pathological metastasis-negative from malignant cases, 11 lymph nodes were detected with micrometastasis by genetic diagnosis.Conclusion Genetic diagnosis of lymph node micrometastasis is more sensitive than conventional pathology and has diagnostic value and merits further study.
To investigate the relationship between clinicopathological features and lymph node metastasis in the primary gastric cancer and affer the basis for deciding appropriate extent of lymph node dissection, a total of 192 patients who underwent curative gastrectomy and lymph node dissection for gastric cancer were analyzed retrospectively. Result: The total rate of lymph node metastasis was 60.4%, with 28.9% of the resected lymph nodes involved. The lymph node metastasis of C, M, A region and the whole stomach were 64.6%, 57.7%, 59.1% and 90.9% respectively. The rates of the lymph node metastasis increased successively in carcinoma of early, middle and late stages (Ｐ＜0.05), the rate of the infiltrative tumor (Borr Ⅲ，Ⅳ) being 76.5% which was significantly higher than that of the circumscribed tumor (Borr Ⅰ，Ⅱ) (43.2%)。 Relating with the tumor size ＜4cm in diameter showed lesser rate, while 4-8 cm and ＞8cm in diameter showed increasingly higher metastaticrate (Ｐ＜0.01). As a result, we should decide the appropriate extent of lymph node dissection during the operation on the basis of clinicopathological stages, type of Borrmann’s, site and maximum diameter of gastric cancer along with the state of lymph node metastasis in carcinoma of different region of the stomach.
Objective To summarize the application and advancement of liver transplantation for hepatic metastasis from neuroendocrine tumor. Methods Domestic and overseas publications on the study of liver transplantation for hepatic metastasis from neuroendocrine tumor in recent years were collected and reviewed. Results Liver transplantation can offer good relief of symptoms, long disease-free intervals, and potential cure in individual patients with hepatic metastatic tumor. Important selection criteria are well-differentiated tumors and a low proliferation rate (Ki67＜10%). Conclusion In carefully selected patients with metastatic neuroendocrine tumors, liver transplantation is an appropriate option.
Objective To investigate the expression of presenilin-2(PS2) and glutathione S transferase π(GSTπ) and their role in the prognosis and therapy of infiltrating ductal breast carcinoma. Methods The expression of PS2 and GSTπ in tumor tissues from 210 patients with infiltrating ductal breast carcinoma confirmed by pathologic examination and treated with modified radical mastectomy was examined by using LSAB immunohistochemical method. Results The expression rate of PS2 was 49.5%(104/210) and the expression rate of GSTπ was 48.1%(101/210). The grade of the postoperative 5-year survival rate and 10-year survival rate in four groups of 210 patients, from high to low, was the group 1 (PS2 positive expression/GSTπ negative expression), the group 2 (PS2 positive expression/GSTπ positive expression), the group 3 (PS2 negative expression/GSTπ negative expression) and the group 4 (PS2 negative expression/GSTπ positive expression). Conclusion The prognosis of the group 1 is the best, the group 2 better, the group 3 good and the group 4 the worst. The results suggest that reasonable use of endocrinotherapy and chemotherapy in infiltrating ductal breast carcinoma is necessary.
目的 探讨乳腺癌改良根治术后影响局部复发与远处转移的相关因素。方法 对陕西省汉中市铁路中心医院略阳医院2000年3月至2007年3月期间行乳腺癌改良根治术且资料完整的637例原发性乳腺癌患者的临床资料进行回顾性分析。结果 66例（10.36%）患者术后发生局部复发和远处转移，其中局部复发50例（7.85%），远处转移16例（2.51%）；术后3～4年内发生复发与远处转移者47例（71.21%）。术后复发和远处转移与患者年龄、肿瘤大小、腋窝淋巴结转移情况、TNM分期、激素受体（ER/PR）表达情况及术后是否接受正规的辅助治疗有关，与患者有无家族史无关。结论 肿瘤大小、腋窝淋巴结转移情况、TNM分期、ER/PR表达情况及术后是否接受正规的辅助治疗是影响乳腺癌改良根治术后复发与远处转移的危险因素，重视乳腺癌术后随访，规范乳腺癌的手术方式，强化乳腺癌的综合治疗是降低乳腺癌改良根治术后复发与远处转移率的主要措施。
ObjectiveTo analyze the value of internal mammary lymph node biopsy via intercostal space in staging and adjuvant therapy of breast cancer. MethodsThe clinical data of 305 breast cancer patients received any kind of radical mastectomy from may 2003 to January 2014 in the Jinan Military General Hospital of PLA were analyzed retrospectively. The patient age, axillary lymph node, and internal mammary lymph node status were integrated to investigate the changing of staging and postoperative adjuvant therapy of the breast cancer. ResultsThese 305 patients were divided into neoadjuvant chemotherapy group and non-neoadjuvant therapy group. There were 67 patients in the neoadjuvant chemotherapy group, including 45(67.2%) patients with axillary lymph node positive, 23(34.3%) patients with internal mammary lymph node positive. There were 23(34.3%) patients who had a change of pathology lympy node (pN) staging and 8(11.9%) patients who had a change of the pTNM staging. Meanwhile, there were 238 patients in the non-neoadjuvant chemotherapy group, including 155(65.1%) patients with axillary lymph node positive, 30(12.6%) patients with internal mammary node positive. There were 30(12.6%) patients who had a change of the pN staging and 23(9.66%) patients who had a change of the pTNM staging. There was a significant difference in the metastasis rate of the internal mammary lymph node (χ2=15.7, P < 0.05) or the changing ratio of the pTNM staging (χ2=5.3, P < 0.05) in two groups. ConclusionsInternal mammary lymph node status could affect pN staging of breast cancer, so do the pTNM staging (TNM, pathology tumor, lymph node, metastasis). The internal mammary lymph node status could guide the postoperative adjuvant radiative therapy by reducing excessive treatment of the internal mammary lymph node area, also could enhance the individual accurate therapy.
Objective To investigate the correlation among lymph node metastasis and clinical features, postoperative survival rate in rectal cancer. Methods Seventy-nine patients who had accepted total mesorectal excision (TME) were collected, and the correlation among their clinical features (including gender, age, tumor size, gross type, depth of infiltration, histology type, differentiated degree and the level of blood serum CEA), lymph node metastasis, and postoperative survival rate were analyzed. Results There was significant correlation between six factors (namely the tumor size, gross type, depth of infiltration, histology type, differentiated degree and the level of blood serum CEA) and lymph node metastasis in single factor analysis. However， multivariate analysis showed that only gross type of tumor and depth of tumor infiltration were related to lymph node metastasis. The postoperative survival time of 43 non-metastasis cases was remarkably longer than that of 33 cases with lymph node metastasis (χ2=18.806， P=0.000), and it was longer in 22 cases with ＜4 lymph nodes metastasis than that of 11 cases with ≥4 lymph nodes metastasis (χ2=4.659， P=0.031). Conclusion In rectal cancer patients the clinical features can reflect the condition of lymph node metastasis in a certain extent, and it can help doctors to evaluate the lymph node metastasis and prognosis.
