ObjectiveTo study the latest progress of neoadjuvant chemotherapy in breast cancer. MethodsLiteratures of neoadjuvant chemotherapy in breast cancer, involving with theoretical basis, clinical significance, indications, drugs, predictors, and its relationship of breastconserving surgery, sentinel lymph node biopsy were reviewed. ResultsNeoadjuvant chemotherapy could reduce the clinical stage, increase opportunity of breast-conserving surgery, learn the sensitivity of drugs, prevent distant metastases, but the impact of the sentinel lymph node biopsy was still in dispute. ConclusionNeoadjuvant chemotherapy is an important part of a systemic treatment for breast cancer, but how to select sensitive drugs, develop individualized treatment programs and forecast the outcome needs further study.
Objective To determine the oncological outcomes following the intersphincteric resection (ISR) for lower rectal cancer and influencing factors. Methods Reviewed the reports on ISR for lower rectal cancer, and summarized the oncological outcomes and influencing factors. The oncological outcomes included local and distant recurrence rates, postoperative survival, and mortality rates. Tumor indicators, surgical techniques, and perioperative radiochemotherapy were included in the influencing factors. Results The recurrence, survival, and mortality rates following ISR resemble traditional operations. Higher stages, metastasis, and non-standard operations affect the oncological outcomes significantly. Preoperative radiochemotherapy could improve the efficacy, but probably at the cost of postoperative anal function. Conclusions The oncological outcomes following ISR are acceptable. The careful case selection and rational arrangements of radiochemotherapy will allow better outcomes.
Platform daytime chemotherapy means that the hospital sets up a fixed area for daytime chemotherapy, and all patients with daytime chemotherapy are treated in the same area. The platform daytime chemotherapy center has the advantages of further optimizing the limited hospital resources, reducing the consumption of medical resources, and improving the efficiency of bed use and patient satisfaction. Its construction is the further sublimation of tumor treatment concept, harmonious relationship between doctors and patients, and humanistic care. This article shares the construction experience of the platform daytime chemotherapy center from the definition, orientation, operation mechanism, ward configuration, drug access, patient access and management mode, and puts forward suggestions that the promotion of the platform daytime chemotherapy center should be carried out from the aspects of policy support, hospital vigorously promoting and self-management breakthrough.
ObjectiveTo summarize the clinical results and safety of photodynamic therapy (PDT) through 4 years after single and multi-treatments of patients with subfoveal choroidal neovascularization (CNV) caused by age-related macular degeneration(AMD). MethodsClinical data of 73 AMD cases (95 eyes) diagnosed through fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography (OCT), treated with PDT were reviewed and analyzed in this hospital from June 2000 to June 2004. The changes of best corrected visual acuity (BCVA), fundus pictures, FFA, ICGA and OCT were compared before and after PDT. Follow-up time varied from 3 months to 4 years (mean, 2 years). ResultsThe mean age of 73 patients was 67.8 years old. The BCVA was from CF/10 cm to 1.0. At the final follow up, the BCVA was improved (increase≥2 lines) in 39 eyes (41.1%), stabilized (±1 line) in 51 eyes (53.7 %) and decreased 2 lines in 5 eyes (5.3%). Fundus hemorrhage and exudation reduced after PDT. FFA and ICGA showed CNV complete closure in 58 eyes (61.05%), partial closure in 6 eyes (6.32%), CNV incomplete closure in 22 eyes (23.16% ) and recurrence in 9 eyes (9.47%). After once PDT of 12 eyes with early-stage AMD, the BCVA improved (from 0.6 to 1.5), CNV completely closed, and the OCT showed disappearance of macular edema and neursensory retinal deta chment. No CN V recurred in our four years follow-up observation and the BCVA of the patients remained stable. The mean number of PDT treatment was 1.8 per eye in 95 cases. No serious local or systemic complications were encountered. ConclusionsSingle or multiple sessions of PDT can acheive long-term safety and efficacy. For early-stage AMD patients with minimally classic CNV, PDT can completely make CNV closed and reduce the risk of visual loss.(Chin J Ocul Fundus Dis，2004，20：275-279)
ObjectiveTo assess the effect of adjuvant chemotherapy for patients with rectal cancer. MethodsThe related randomized controlled trials comparing patients underwent radical surgery for rectal cancer with (adjuvant chemotherapy group) or without (surgery alone group) adjuvant chemotherapy, were retrieved from the databases such as PubMed, Cochrane Library, EMBAS, CBM, CNKI, WanFang, and VIP, then using RevMan 5.2 software to conduct the Meta-analysis. ResultsA total of 8 articles involving 3 654 patients were included. The results of Meta-analysis showed that:①for all patients with rectal cancer, the 2-(OR=1.28, 95% CI: 1.05-1.57, P=0.020), 3-(OR=1.28, 95% CI: 1.09-1.51, P=0.003), and 5-year (OR=1.21. 95% CI: 1.05-1.40, P=0.008) survival rates of adjuvant chemotherapy group were higher than those of surgery alone group, respectively.②For patients with rectal cancer ofⅡstaging, compared with surgery alone group, the 5-year survival rate was higher in adjuvant chemotherapy group (OR=1.39, 95% CI: 1.09-1.78, P=0.009), but 5-year recurrence rate was lower in adjuvant chemotherapy group (OR=0.65, 95% CI: 0.49-0.87, P=0.003).③For patients with rectal cancer ofⅢstaging, compared with surgery alone group, the 5-year recurrence rate was lower in adjuvant chemotherapy group (OR=0.40, 95% CI: 0.26-0.64, P=0.000 1), but there was no significant difference on the 5-year survival rate (OR=1.27, 95% CI: 1.00-1.61, P=0.050). ConclusionCompared with radical surgery, radical surgery combined with postoperative adjuvant chemotherapy can improve the survival and reduce the recurrence for patients with rectal cancer.
Objective To summarize the research progress of the adenocarcinoma of esophago-gastric junction (AEG) in recent years, in order to improve the further understanding of this disease. Method The literatures about application and research progress of AEG were researched and reviewed. Results Siewert classification was a widely recognized classification for AEG, according to this classification, AEG was divided into typeⅠ, Ⅱ, and Ⅲ. Gastroesophageal reflux, Barrett’ sesophagus, and the infection of Helicobacter pylori may be the important pathogenic factors. For SiewertⅠAEG, thoracic approach was preferred commonly, and for SiewertⅡand Ⅲ AEG, total gastrectomy through abdominal approach and distal partial resection of esophagus through diaphragmatic hiatus approach were recommended. Endoscopic submucosal resection, neoadjuvant therapy, targeted therapy, and multidisciplinary team were becoming more and more important in the treatment of AEG. Conclusions The choice of surgical method and resection range should according to the types of AEG. Comprehensive assessment and comprehensive treatment would be performed, so that effect of treatment may be improved.
Objective To evaluate short-term effects of a single photodynamic therapy (PDT) treatment with visudyne (CIBA Vision Corp.) for choroidal neovascularization (CNV) in age-ralated macular degeneration (AMD). Methods Thirty cases (35 eyes) diagnosed as AMD patients with classic CNV were treated with PDT. The data of visual acuity testing, fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography （OCT) were used to evaluate the effects of a single treatment of PDT before and 1 week, 1 ,3 month after treatment. Results The visual acuity of 34 eyes were stable or improved in 3 months follow-up；and the visual acuity of 1 eye was decreased. Decrease or dispearance of fluorescein leakage from CNV was noted in 19 eyes. No serious complication occurred. Conclusion Single treatment of PDT for CNV in AMD can achieve short-term decrease or cessation of fluorescein leakage from CNV without loss of visual acuity.

ObjectiveTo evaluate the efficacy and toxicity of TEC and CEF regimen in preoperative chemotherapy for patients with breast cancer. MethodsA total of one hundred breast cancer patients undergoing preoperative chemotherapy were divided into TEC group (n=50) and CEF group (n=50) by the pairgroup method and received surgical therapy after three courses of chemotherapy. The efficacy and toxicity of preoperative chemotherapy of patients in two groups were analyzed. ResultsFour patients with stage ⅢB breast cancer quit from CEF group after two courses of treatment because of the worse satisfaction. Clinical complete remission (cCR) was 7 cases, clinic partial remission (cPR) was 34 cases, stable disease (SD) was 9 cases, therefore, the remission rate (RR) was 82.0% (41/50), and reduction rate of tumor was 64.0% (32/50) in TEC group. cCR was 2 cases, cPR was 32 cases, SD was 12 cases, thus the RR was 680% (34/50), and reduction rate of tumor was 40.0% (20/50) in CEF group. The clinical efficacy and reduction rate of tumor of patients in TEC group were significantly superior than those in CEF group (Plt;0.05). The negative conversion ratio of lymph nodes were 54.1% (20/37) and 57.1% (20/35) in TEC group and CEF group, which was not statistically different (Plt;0.05). The occurrence of hair loss and leukopenia of patients in TEC group were significantly higher than those in CEF group (Plt;0.05), while the differences in thrombocytopenia, low concentration of hemoglobin, nausea, vomiting, diarrhea, cardiac toxicity, and neurotoxicity were not significant (Pgt;0.05). ConclusionTEC regimen is better than CEF regimen in the efficacy and safety of neo-adjuant therapy for patients with breast cancer, and well tolerated.
The effects of preoperative selective arterial perfusion chemotherapy (PSAPC) in the treatment of 20 cases of histologically confirmed gastric cancers is reported in which 12 patients were operated on, and a comparison with that of general chemotherapy in 10 cases of gastric cancers (as controls) was made. In the PSAPC group, besides the improvement of clinical symptoms and singns, the cancer cells of lesions in situ and metastatic lymph nodes have different degrees of degeneration and necrosis. This result show significant differences in two group comparison (Plt;O.01). We conclude that the PSAPC has good short-term effect and little side-effect. It can improve the resection rate and radical resection rate, and prevent the iatrogenic metastasis and implantation during operation, and decrease the postoperative recurrence of the patients with gastric cancer.
