Objective To explore the clinical efficacy of early breast cancer patients underwent breast-conserving surgery with postoperative chemotherapy and radiotherapy.Methods A retrospective analysis of 128 early breast cancer patients underwent routine breast-conserving surgery was conducted.The clinical effect and cosmetic results were analyzed by the follow-up results of 128 cases.Results (1) The 5-year follow-up rate was 100％,overall survival rate was 95.3％,1-year survival rate was 100％ (128/128) ;3-year survival rate was 98.4％ (126/128) ;5-year survival rate was 95.30％ (122/128).Postoperative follow-up 6 patients died,3 patients died of liver metastases,2 patients died of lung metastases,1 patient died of non-cancerous reasons.The local recurrence rate was 2.34％ (3/128),axillary lymph node recurrence rate was 1.56％ (2/128).The average recurrence time was three years and two months after operation,distant metastasis rate was 3.91％ (5/128).(2) Beauty evaluations of 128 patients with breast-conserving surgery were excellent in 71 cases (55.5％),good in 55 cases (43.0％),and poor'in 2 cases (1.6％).Good,acceptable as acceptance criteria,the acceptance rate was 98％.Conclusion Breast-conserving surgery is not only to a certain extent to solve the pursuit of female beauty,but also improve their quality of life.But only the complete elimination of residual lesions in order to truly ensure that no recurrence of tumor.Therefore,the appropilate survival rate of patients for radiotherapy and chemotherapy can be extended so that the patient's breast to maintain a good shape.Breast-conserving surgery combined with radiotherapy and chemotherapy is superior to the modified radical surgery,and popularization in the hospital.

Objective To investigate the value of laparoscopy in the diagnosis and treatment of unexplained chronic abdominal pain.Methods From January 2014 to February 2016, clinical data of 56 unexplained chronic abdominal pain undergoing laparoscopic surgery were analyzed retrospectively.Laparoscopic exploration was performed firstly and then the corresponding abnormalities were diagnosed and dealt with accordingly.Results The disease causes were explicit in 48 cases (85.7%), including 25 cases of abdominal adhesions, 8 cases of chronic appendicitis, 2 cases of small intestinal diverticulum, 2 cases of intestinal tuberculosis, 2 cases of lymphoma, 5 cases of endometriosis, 2 cases of tubal adhesions, 1 case of peritoneal metastasis of gastric cancer after surgery, and 1 case of appendiceal mucinous adenocarcinoma.Surgical treatment was performed in 43 cases, 3 of whom were converted to laparotomy.There were no postoperative complications in the 56 cases.The follow-up rate was 92.9% (52/56), and lost of follow-up was in 4 cases.The follow-up duration was from 3 months to 3 years (median, 19.4 months).There was 1 death case (peritoneal carcinomatosis).There were 35 cases (62.5%) of complete relief of abdominal pain (no recurrence of preoperative abdominal pain symptoms) and 12 cases (21.4%) of pain relief (preoperative pain decreased or interval extended).The total effective rate was 83.9% (47/56).Conclusion Laparoscopy is of high value in the diagnosis and treatment of unexplained chronic abdominal pain.

Objective To discuss the angiogenic e ffects on tumor micrometastasis. Methods Literatures on the relation between tumor angiogenesis and micrometastasis were reviewed. Results Tumor angiogenesis was a basis of the devel opment of micrometastasis.Conclusion Micrometastic dependence on angiogenesi s gestates a novel revolution of tumor treatment.

Objective To evaluate the safety and efficacy of endoscopic techniques for diagnosis and treatment of breast diseases. Methods Related literatures of recent years were reviewed. Results A minimally invasive endoscopic technique can be performed through small incisions. This can contribute greatly to reducing postoperative pain, shortening recovery time, and achieving a good cosmetic outcome. Under endoscopy, meticulous dissection and hemostasis can be achieved. Endoscope assisted subcutaneous mastectomy, immediate mammary reconstruction, sentinel lymph node biopsy and axillary lymph node dissection, for breast cancer can be performed safely. Endoscopic surgery can also be applied for the diagnosis and treatment of benign breast tumor and transaxillary removal of glandular tissue in gynecomastia. In addition, fiberoptic ductoscopy can be used to diagnose patients with nipple discharge. Endoscopic surgery for patients with breast diseases can offer an excellent cosmetic outcome and maintain normal physiologic functions without a noticeable scar. It helps to give the patients confidence and improve the quality of life. Conclusion Breast surgery is a good candidate for endoscopic techniques.

Objective To evaluate the clinical significance of CEA mRNA expression in gallbladder bile for early diagnosis of liver metastasis from primary colorectal cancer. Methods [WT5”BZ] A CEA specific nest RT PCR assay was used to detect CEA mRNA expression in the gallbladder bile of 46 patients with colorectal cancer. Results The positive rate of CEA mRNA in gallbladder bile was 74%. The rate was directly proportional to that of live metastasis. Liver metastasis developed in 33% of patients with positive CEA mRNA expression. Conclusions The positive expression of CEA mRNA in gallbladder bile is a proof of prospective liver metastasis.

Objective　 To study the significance of monitoring postoperative hematogenous micrometastasis of colorectal cancer．　 Methods　 The micrometastatic cancer cells in peripheral blood and bone marrow of the perioperative patients were investigated by CK20 mRNA RT-PCR.　 Results　 The positive rates(16.3%) of hematogenous dissemination without relapse or metastasis after operation were significantly lower than that(88.9%) in patients with postoperative relapse or metastasis. There were four types of hematogenous dissemination. (1) Postoperative temporary negatives.(2)Consistant positives. (3) CK-20 turned positive postoperatively. (4) Consistant negatives. All the 6 patients that died had positive CK-20 preoperatively.　 Conclusions　 The hematogenous dissemination of colorectal cancer plays an important role in postoperative relapse. The dynamic monitoring of CK-20 predicts hematogenous dissemination of colorectal cancer.

Objective To study the feasibility of laparoscopic total mesorectal excision(TME) for low rectal cancer.Methods Laparoscopic total mesorectal excision was performed in 126 patients with low rectal cancer according to TME principle.Results The operation time was 95 - 180 min,with an average time of ( 117 ± 21 ) min,the amount of bleeding 50 - 200 ml,with an average amount of (90 ± 27 ) ml.2 - 3 days after surgery,gastrointestinal function was restored.Hospital stay was 6 - 14 days,with an average of (8 ± 2)days.Four cases converted to open surgery,the conversion rate for laparotomy was 3.2％.The proportion of sphincter-preserving operation was 95.24％ (120/126).No instant or delayed injury of ureters,large bleeding in front of sacrum and other operation-related severe complications happened intra-and after operation.Conclusion Laparoscopic surgery for low rectal cancer is safe and feasible.

Objective To explore the feasibility of endoscopic thyroidectomy through the approach of areola of breasts.Methods Endoscopic thyroidectomy via areola of breasts approach was carried out in 26 cases from March 2003 to September 2005.Thyroid nodules were right-sided in 13 cases,left-sided in 10 cases,bilateral in 1 case,and not palpable in 2 cases of hyperthyroidism(grade 1).There were 9 cases of solitary nodule and 15 cases of multiple nodules.The nodules were cystic in 5 cases,solid in 13 cases,and mixed in 6 cases,with 1~4 cm in diameter.Preoperative diagnoses included 9 cases of thyroid adenoma,15 cases of nodular goiter,and 2 cases of primary hyperthyroidism.Results The thyroidectomy was performed successfully under endoscope in 25 cases,with an operation time of 50~210 min(mean,112 min),including 4 cases of tumor enucleation,10 cases of unilateral partial thyroidectomy,8 cases of bilateral partial thyroidectomy,and 3 cases of bilateral subtotal thyroidectomy with isthmus resection.A conversion to open surgery was required in 1 case owing to thyroid carcinoma with trachea involvement.Pathological findings showed 4 cases of thyroid adenoma,18 cases of nodular goiter,2 cases of primary hyperthyroidism,and 2 cases of thyroid carcinoma.The drainage tubes were removed at 24~48 hours after operation.No nerve or parathyroid injuries occurred.The length of postoperative hospital stay was 3~6 d(mean,4.2 d).Follow-up observations in 25 cases for 3~33 months(mean,13 months) revealed no local recurrence.The patients were satisfied with cosmetic effects.The 2 cases of thyroid carcinoma were followed for 9 and 11 months,respectively,presenting no recurrence or metastasis.Conclusions Endoscopic thyroidectomy via areola of breasts approach is feasible and effective,offering satisfactory cosmetic outcomes.

Objective To evaluate effects of neoadjuvant chemotherapy on axillary lymph node status in patients with breast cancer.Methods A total of 45 patients with stage Ⅱ or Ⅲ breast cancer treated with neoadjuvant chemotherapy followed by surgery(Combination Group) were compared with 79 patients with breast cancer treated with initial surgery only(Surgery Group) in respect of axillary lymph node status,including the total number of the lymph nodes and the number of positive and negative lymph nodes,according to findings of physical examination,B-ultrasonography,and molybdenum target radiography.Results The total number of the lymph nodes and the number of positive lymph nodes were significantly less in the Combination Group(16.9?5.9 and 2.5?2.2) than in the Surgery Group(20.8?8.0 and 3.9?3.0)(t=-2.856,P=0.005;t=2.790,P=0.006),whereas the number of negative lymph nodes were 14.4?5.4 and 16.7?7.0 in the Combination Group and the Surgery Group,respectively,without statistical significance(t=-1.904,P=0.055).Four patients were found loco-regional relapse in each group during follow-up checkups for 6~19 months(mean,10 months) in 40 patients in the Combination Group and 7~21 months(mean,12 months) in 67 patients in the Surgery Group.Conclusions Total and positive axillary lymph nodes retrieved after axillary lymph node dissection decrease in number after neoadjuvant chemotherapy.

The dynamic changes of the T cell subsets in the peripheral blood and the serum level of immunoglobin and complement C3 were observed in 32 breast cancer patients before and after surgery and after radiotherapy.20 patients with benign breast diseases and 20 normal women were observed likewise.It was found that the Ts cells and serum IgG and IgA were significantly increased and the TH/Ts ratio markedly decreased in the breast cancer group as compared with those of other 2 groups.In the first postoperative week,TH cells and TH/TS ratio were markedly decreased in all cases operated on.One month after operation,all the parameters returned nearly to the normal level in the group with benign breast diseases.In the group without radiotherapy,the proportion of OKT3+ cells in the 3rd postoperative month and OKT4+ cells in the 6th postoperative month exceeded the preoperative level while that of OKT8+ cells decreased.In the first week after radiotherapy,TH cells decreased,Ts cells increased and TH/Ts ratio decreased significantly.Meanwhile serum IgG was elevated.OKT3+ cells markedly increased in the 6th month after radiotherapy and OKT8+ cells decreased 1 year after that.The immunore-active state of breast cancer patients and the effects of therapeutic measures on them were discussed.
