Cancer Research and Clinic 2011;23(12):793-795,806
The metastases status of internal mammary lymph node(IMLN) is an independent prognostic factor for breast cancer and it also is an important reference for neoplasm staging.The patients with IMLN metastases consistently have worse outcomes.The overall risk of IMLN metastases is 18 %-33 %.Metastases exclusively situated in the IMLN,without concurrent axillary metastases,occur in 2 %-11% of patients.Factors related to IMLN metastases include the status of axillary node,the age of patients,the localization and characteristics of primary tumor.Recently,with the development of sentinel lymph node biopsy(SLNB), internal mammary-SLNB may access the status of IMLN with a minimal risk. Internal mammary-SLNB procedure can improve the system for nodal staging of breast cancer,and it will contribute to the individualized treatment for breast cancer patients.

This paper analysed the rhinoscope's clinical value in microsurgical treatment of intracranial aneurysms. Application of the rhinoscope in 87 patients, only 2 patients had ruptured during operation. However, 11 cases had ruptured in 94 cases without using rhinoscope, P < 0.05, they had a significant difference. By DSA follow-up review, 82 cases of used rhinoscope only 2 cases had remained the aneurysm neck, but 9 cases had the aneurysm neck in 77 cases which had not used the rhinoscope in the microsurgical treatment, P < 0.05, they also had significant difference. The application of rhinoscope in microsurgical treatment of intracranial aneurysms intraoperative, can reduce the risk of the intraoperative aneurysm rupture. It can achieve better clinical effect.

Objective To study the serum level of macrophage inflammatory protein-1α(MIP-1α) and interferon gamma inducible protein-10 (IP-10) in acute myelogenous leukemia (AML) and clarify their clinical significance. Methods Enzyme-linked immunosorbent assay was used to detect the level of MIP-1α and IP-10 in serum samples from 34 AML patients(observation group) and 20 volunteers (normal control group). Results The levels of MIP-1αand IP-10 in observation group before induction chemotherapy were significantly higher than those in normal control group (P<0.05). The levels of MIP-1αand IP-10 in observation group after induction chemotherapy were decreased, and significantly lower than those before induction chemotherapy (P<0.05). After treatment for one course, 21 patients reached complete remission (CR), and 13 patients did not reach CR. The levels of MIP-1αand IP-10 in CR group had no significant difference compared with those in normal control group (P<0.05), but the levels of MIP-1αand IP-10 in none CR group were significantly higher than those in normal control group and CR group (P<0.05). The drop percentage of MIP- 1αlevels in CR group and none CR group was (32.51 ± 10.34)% and (10.57 ± 10.39)%, and there was significant difference (P<0.05). The drop percentage of IP-10 levelsin CR group and none CR group was(45.94 ± 13.68)% and (31.17 ± 11.85)%, and there was significant difference (P<0.05). Liner correlation analysis revealed that the levels of MIP-1αand IP-10 had significantly positive correlation in AML patients (r=0.652, P<0.05). Conclusions Different expressions of serum MIP-1α and IP-10 are found before and after induction chemotherapy AML patients, and there is significant correlation. Combined detection of serum MIP-1αand IP-10 may be used as an index to monitor clinical stages and prognosis.

Objective: To explore the security and the radical and clinical value of thoracoscopic-laparoscopic esophagectomy with two-field lymph node dissection for middle esophageal cancer through comparison with open esophagectomy. Methods: A total of 410 stage II to stage III esophageal cancer patients who underwent two-field lymph node dissection with two different methods (thora-colaparoscopic esophagectomy and open esophagectomy) from January 2009 to July 2013 in Uninon Hospital, Fujian Medical Universi-ty, were analyzed retrospectively. General pathological parameters, operative procedures, and short-term outcomes were collected and compared between the two groups (TLG and OG). Results: No significant differences were found regarding general pathological pa-rameters, such as gender, age, etc. Significant differences between thoracolaparoscopic and open two-field lymph node dissection esoph-agectomy were observed in terms of esophagectomy intraoperative blood loss [(206 ± 138) mL vs. (240±111) mL] and the mean num-ber of dissected lymph node per person [(26.6±8.6)/per vs. (21.7±9.2)/per]. Overall postoperative morbidity rate in OG was 35.2%, and its difference from that of TEG (25.8%) is statistically significant (P<0.05). Regarding single complications, such as pulmonary infec-tion and arrhythmia, OG showed evidently superior results (P<0.05). Meanwhile, anastomotic stricture and hoarseness rate are higher in TEG (P<0.05), and the difference was statistically significant as well. Conclusion: Thoracolaparoscopic two-field esophagectomy is technically feasible and safe and can achieve radical tumor resection.
