Objective： To evaluate the clinical effect of transarterial infusion chemotherapy of gemcitabine plus three dimensional conformal radiotherapy on patients with local advanced pancreatic cancer. Methods： Fifty-one patients with local advanced pancreatic cancer from June 2002 to February 2004 were enrolled, twenty-four patients of combined group were treated with transarterial infusion chemotherapy of gemcitabine plus three dimensional conformal radiotherapy, while twenty-seven patients of control group were treated only with transarterial infusion chemotherapy of gemcitabine. Results： There were significant statistical differences between two groups in clinical benefit response （91.7% versus 74.1%, P 〈 0.01） and overall remission rate （70.8% versus 33.3%, P 〈 0.01）. The 6-month survival rate, 12-month survival rate and 24-month survival rate of combined group were 83.3%, 62.5% and 37.5% respectively, while that of control group were 55.6%, 33.3% and 11.1% respectively. This showed significant difference between the two groups. Conclusion： Transarterial infusion chemotherapy of gemcitabine plus three dimensional conformal radiotherapy may be better than single transarterial infusion chemotherapy of gemcitabine in improving survival rates and elongating survival time of patients with local advanced pancreatic cancer.     

吉西他滨联合奥沙利铂治疗晚期胰腺癌30例

Objective: To evaluate the activity and safety of combination chemotherapy with gemcitabine plus oxaliplatin (GEMOX regimen) in patients of advanced pancreatic carcinoma. Methods: 30 patients with advanced pancreatic cancer were enrolled into this study. All patients received gemcitabine 1000 mg/m2, given by 30-minute intravenous infusion, on days 1 and 8 of each 21-day cycle. Oxaliplatin 100 mg/m2 was administered as a 2 h infusion on day 1 of each 21 day. Clinical outcomes for patients treated with two cycles of chemotherapy were evaluated according to WHO criteria. Results: All 30 patients were eligible for effectiveness and safety analysis. Objective response rate was approximately 20.0%. Clinical benefit response (CBR) was a composite of assessment of pain, performance status and body weight. The pain relief rate, improve-ment rate of performance status and body weight were 53.3%, 46.7% and 36.7%, respectively. The main adverse effects were bone marrow depression, peripheral nerve toxicity and gastrointestinal reaction. There was no treatment-related death during the chemotherapy. Conclusion: The high response rate with low toxicity observed in this study suggests that GEMOX regimen may be an effective alternative curative treatment for patients with advanced pancreatic carcinoma and can be used more extensively in clinical practice.

Objective： To observe the efficacy of Shenmai injection in the treatment for adverse reactions of chemotherapy on advanced non-small cell lung cancer （NSCLC）. Methods： 45 NSCLC patients with stages IIIb-IV were randomly divided into two groups： the treatment group （treated by chemotherapy combined with Shenmai injection） and the control group （treated by chemotherapy only）. The efficacy of the two groups was evaluated after 3 cycles of treatment. Results： There was no significant difference between the two groups in the recent curative effects （P 〉 0.05）, while there were significant differences between them in Karnofsky score and weight （P 〈 0.05）. The treatment group was better than the control group in preventing leucopenia and decreased hemoglobin, and significant differences were found between them （P 〈 0.05）. The incidence of thrombocytopenia, nausea and vomiting, hepatic and renal dysfunction in the treatment group was lower than that in the control group, but no significant differences were found between them （P 〉 0.05）. Conclusion： Shenmai injection would not influence the efficacy of chemotherapy on advanced NSCLC patients, while it could improve the quality of life, increase the body weight of patients, alleviate adverse reactions of chemotherapy as myelosuppression so as to improve the tolerance of organism to chemotherapy.     

术前支气管动脉灌注化疗在肺癌手术中的临床研究

Objective： How to improve the postoperative 5-year survival rate for lung cancer and to give more patients a chance of surgery have become research hotspots. The aim of this research is to evaluate the clinical and pathohistological responses and effects of preoperative bronchial artery infusion （BAI） chemotherapy in patients with locally advanced （stage Ⅲ） non-small cell lung cancer （NSCLC）. Methods： A total of 92 patients with locally advanced NSCLC were randomly divided into two groups. BAI group received BAI chemotherapy for 2 cycles before surgical resection. Surgery group received operation only. The complete resection rate and clinical response were compared between the two groups. Results： In the BAI group, the clinical response rate and the pathohistological response rate were 68.3% and 51.3%, respectively. The complete resection rate in the BAI group was 89.7%, which was significantly higher than that in the surgery group （72.5%） （P 〈 0.05）. The 1- and 2-year survival rate was 100.0% and 80.6% in the BAI group, and 94.1% and 60.0% in the surgery group. Conclusion： BAI neoadjuvant chemotherapy is safe and effective, which has a good clinical and pathohistological response. It might increase the complete resection rate of the tumor and improve the long term survival rate of stage Ⅲ NSCLC patients.     

Prognostic significance of ERCC1 expression in postoperative patients with gastric cancer

Aim： This study explored the correlation between the expression of excision repair cross-complementation group 1 （ERCC1） and the prognosis of gastric cancer patients. Methods： From January 2005 to December 2008, 605 patients who underwent radical surgery in The First Affiliated Hospital of Nanjing Medical University were enrolled. We conducted the follow-up every 6 months and its contents included a comprehensive medical history, tumor markers and abdominal ultrasound or CT and other imaging findings. Deadline was April 30, 2013 and follow-up time between 51 to 91 months. Survival time is calculated from the date of diagnosis to death or last follow-up date. Immunohistochemistry （IHC） was used to assess the expression of ERCCI in resected samples. The relationship between ERCCI expression and survival of patients was investigated. The comparison of count data were analyzed by Chi-square test. Median survival time （MST） and the 5-year survival rate were calculated by life table analysis. The Kaplan-Meier curves were used for survival analysis. Results： ERCC1 expression was positive in 412 patients （68.1%）. There is no significant difference between ERCCl-positive group and ERCCl-negative group in terms of the MST and 5-year survival rate （P=0.455）. The MST and 5-year survival rate have no significant difference （P=0.162） between group with chemotherapy and group with no chemotherapy in patients with ERCCl-positive expression. However, the MST and 5-year survival rate in patients with ERCCl-negative expression benefited more from with chemotherapy （P=0.019）. The ERCCl-positive patients survived longer than those ERCCl-negative patients （P=0.183） in subgroup with no adjuvant chemotherapy. In the subgroup analysis, ERCC 1 expression had no significant relationship with overall survival in patients with stage II or llI gastric cancer （P〉0.05）. Conclusions： ERCC1 might be a good prognostic factor for the patients of gastric cancer after radical resection. Patients with ERCC     

Intraarterial chemotherapy with gemcitabine and cisplatin in locally advanced or recurrent penile squamous cell carcinoma

The prognosis of locally advanced or recurrent squamous cell carcinoma （SCC） of the penis after conventional treatment is dismal. This study aimed to evaluate the therapeutic effects of intraarterial chemotherapy with gemcitabine and cisplatin on locally advanced or recurrent SCC of the penis. Between April 1999 and May 2011, we treated 5 patients with locally advanced penile SCC and 7 patients with recurrent disease with intraarterial chemotherapy. The response rate and toxicity data were analyzed, and survival rates were calculated. After 2 to 6 cycles of intraarterial chemotherapy with gemcitabine and cisplatin, 1 patients with Iocoregionally advanced disease achieved a complete response, and 4 achieved partial response. Of the 7 patients with recurrent disease, 2 achieved complete response, 3 achieved partial response, 3 had stable disease, and 1 developed progressive disease. An objective tumor response was therefore achieved in 10 of the 12 patients. The median overall survival for the patients was 24 months （range, 10-50 months）. Three out of 10 patients who responded were long-term survivors after intraarterial chemotherapy. Intraarterial chemotherapy with gemcitabine and cisplatin may be effective and potentially curative in Iocoregionally advanced or recurrent penile SCC. The contribution of this therapy in the primary management of advanced or recurrent penile SCC shouJd be prospectively investigated.     

Clinical study of combining chemotherapy of oxaliplatin or 5-fluorouracil/leucovorin with hydroxycamptothecine for advanced colorectal cancer

OBJECTIVE To estimate effects, survival rate after the short-time efficacy, side the treatment of combining chemotherapy of oxaliplatin or 5-fluorouracil/leucovorin with hydroxycamptothecine （HCPT） for the patients with advanced colorectal cancer.
METHODS From January 2002 to November 2005, 59 patients with advanced colorectal cancer confirmed by pathology were enrolled into this study in the department of medical oncology, in the Sixth People＇s Hospital of Shanghai Jiaotong University, Shanghai. Patients＇ characteristics in two groups were similarly confirmed by statistic. All 37 patients in OH group received oxalip21atin （130 mg/m^2 d1） plus hydroxycamptothecine （6 mg/m d1-4）, and all 22 patients in the HLF group received hydroxycamptothecine （6 mg/m^2 d1-4） plus leucovorin （300 mg d1-5） and 5-fluorouracil （0.375 g/m^2 d1-5）. The regimens in both groups were 21-day cycle that was repeated three weeks. The side effects were evaluated. The efficacy was estimated after two cycles of chemotherapy for each patient.
RESULTS The efficacy of the treatment in the OH group with 37 patients and in the HLF group with 22 patients was estimated. The overall response rate （CR ＋ PR） was 32.4% in the OH group and 22.7% in the HLF group. There was no complete response （CR） and there was no statistical significantly difference （%2= 0.876, P = 0.704） in two groups. The 1-year survival rate was 30.98% in the OH group and 15.02% in the HLF group, and it had no significant difference between the two groups. The median PSF and OS were 5.83 months and 11.17 months in the OH group vs. 7.40 months and 10.48 months in the HLF group, and it had no significant differences between the two groups （P 〉 0.05）. The major side effects of grade III and IV in the two groups were myelosuppression and gastrointestinal reactions. The statistically significant difference in side effects appeared in leukopenia （χ^2= 17.173, P = 0.001）, nausea/vomiting （χ^2= 6.426, P = 0.039）, diarrhea （χ^2= 16.245, P = 0.000） and peripheral neuropathy. CONCLUSION The efficacy was almost equal between the OH and the HLF groups, and the two regimens can be used as the second-line treatments for the patients with colorectal cancer. Leucopenia, nausea, diarrhea and peripheral neuropathy appeared more in OH group, and anemia and thrombocytopenia were almost equal between the OH and the HLF groups.     

Analysis of the curative effect of preoperative intra-arterial infusion chemoembolization on stage IB<Subscript>2</Subscript>-IIB uterine cervix cancer

OBJECTIVE To investigate the short-term and long-term therapeutic efficacy of preoperative intra-arterial＇infusion chemoembolization on stage IB2-IIB uterine cervix cancer （UCC）.
METHODS A total of 143 patients with Stage IB2-IIB UCC were divided into a clinical trial group and a control group. The patients in the clinical trial group （n = 86） were treated with a combined therapy, i.e., preoperative intra-arterial infusion chemoembolization, surgical therapy and postoperative radiotherapy, and those in the control group （n = 57） were given surgical therapy and post-operative radiotherapy. The adverse effects, changes in local lesion and pathological examinations of the cancer, and the state during the surgery were observed after the intra-arterial infusion chemo-embolization. The survival rate and recurrence rate between the two groups were compared.
RESULTS The total effective rate of the intra-arterial infusion chemo-embolization on Stage IB2-IIB UCC was 93.02%. The treatment could reduce tumor size, bring about retro-conversions of the clinical stage of the tumors and pathological grade of the cancer cells, and decrease the quantity of intra-operative blood loss as well as the operating time. It could significantly improve the 5-year survival rate （P〈 0.05）, and reduce the 2 and 5-year tumor recurrence rates （P 〈 0.05）. Moreover, its side effects were little.
CONCLUSION Preoperative intra-arterial infusion chemoembolization can create conditions for radical operation, lower the postoperative recurrence rate, and improve the prognosis in the patients with UCC. It is an effective therapy in treating UCC.     

Re-challenge chemotherapy with gemcitabine plus carboplatin in patients with non-small cell lung cancer

Despite recent improvements to current therapies and the emergence of novel agents to manage advanced non-small cell lung cancer(NSCLC),the patients′overall survival remains poor.Re-challenging with first-line chemotherapy upon relapse is common in the management of small cell lung cancer but is not well reported for advanced NSCLC.NSCLC relapse has been attributed to acquired drug resistance,but the repopulation of sensitive clones may also play a role,in which case re-challenge may be appropriate.Here,we report the results of re-challenge with gemcitabine plus carboplatin in 22 patients from a single institution who had previously received gemcitabine plus platinum in the first-line setting and had either partial response or a progression-free interval of longer than 6 months.In this retrospective study,the charts of patients who underwent second-line chemotherapy for NSCLC in our cancer center between January 2005 and April 2010 were reviewed.All the patients who received a combination of gemcitabine and carboplatin for re-challenge were included in the study.These patients were offered second-line treatment on confirmation of clear radiological disease progression.The overall response rate was 15%and disease control rate was 75%.The median survival time was 10.4 months,with 46%of patients alive at 1 year.These results suggest that re-challenge chemotherapy should be considered in selected patients with radiological partial response or a progression-free survival of longer than 6 months to the initial therapy.     

High-risk endometrial cancer may be benefit from adjuvant radiotherapy plus chemotherapy

Objective:To present patterns of practice and outcomes in the adjuvant treatment of intermediate-and high-risk endometrial cancer.Methods:Retrospective data on 224 women with intermediate-risk and high-risk endometrial cancer from 1999 to 2006 were reviewed.All patients underwent surgical staging.Patterns of adjuvant treatment,consisting of pelvic radiotherapy,chemotherapy,and radiotherapy plus chemotherapy,were assessed.The 3and 5-year disease-specific survival(DSS) rates were calculated using the Kaplan-Meier method.Results:The difference in 5-year DSS rate was statistically significant between adjuvant group and non-adjuvant group(80.65% vs.63.80%,P=0.040).In 110 high-risk patients who underwent adjuvant treatment,both 5-year DSS rate and recurrent rate were significantly different in combined radiotherapy and chemotherapy group compared with radiotherapy alone and chemotherapy alone groups(DSS rate,P=0.049;recurrent rate,P=0.047).In 83 intermediate-risk women who underwent adjuvant treatment,there was no significant difference in 5-year DSS rate and recurrence rate among the combined radiotherapy and chemotherapy,radiotherapy alone and chemotherapy alone groups(DSS rate,P=0.776;recurrent rate,P=0.937).Conclusions:Adjuvant radiotherapy plus chemotherapy is associated with a higher 5-year DSS rate and lower recurrence rate compared with radiotherapy alone and chemotherapy alone in high-risk endometrial cancer patients.Patients with intermediate-risk endometrial cancer may be not likely to benefit from adjuvant combined radiotherapy and chemotherapy.

Objective: To compare the curative effectiveness of continuous transarterial infusion chemotherapy and systemic venous chemotherapy in treating patients with advanced pancreatic cancer, and to evaluate the value of selective continuous transarterial infusion chemotherapy in treating advanced pancreatic cancer. Methods: Of the 51 patients with advanced pancreatic cancer receiving chemotherapy with gemcitabine and 5-fluorouracil, 25 patients were treated with selective continuous transarterial infusion chemotherapy, 26 were treated with systemic venous chemotherapy, and curative effectiveness was analyzed retrospectively. Curative effectiveness included tumor volume, clinical benefit response (CBR), acute and subacute toxic reactions of antitumor drugs, survival rate and median survival time. Results: The objective effective rate in transarterial group was 32.0% versus 23.1% in systemic group without any significant difference (P = 0.475). Clinical benefit rates in transarterial group and systemic group were 80.0% and 50.0% respectively (P = 0.025). The 6-, 9- and 12-month accumulated survival rates and median survival time in transarterial group were higher than those of the systemic group (P = 0.002), the differences were statistically significant. However, the adverse reactions between the two groups were not statistically significant. Conclusion: Compared with systemic chemotherapy, continuous transarterial infusion chemotherapy with gemcitabine and 5-fluorouracil could improve clinical benefit rate and survival time of patients with advanced pancreatic cancer, it is safe and reliable, and the adverse reactions is less.     

Continuous transarterial infusion chemotherapy with gemcitabine and 5-Fluorouracil for advanced pancreatic carcinoma

Purpose: Pancreatic carcinoma is one of the most malignant tumors of the alimentary system, with relativelyhigh incidence rates. The purpose of this study was to assess the efficacy and safety of two regimens for advancedpancreatic carcinoma: continuous transarterial infusion versus systemic venous chemotherapy with gemcitabineand 5-fluorouracil. Methods: Of the 48 patients with advanced pancreatic carcinoma receiving chemotherapy withgemcitabine and 5-fluorouracil, 24 received the selective transarterial infusion, and 24 the systemic chemotherapy.For the continuous transarterial infusion group (experimental group), all patients received gemcitabine 1000mg/m2,given by 30-minute transarterial infusion, on day 1 of a 4-week cycle for 2 cycles, and a dose of 600 mg/m2 5-fluorouracil was infused on days 1~5 of a 4-week cycle for 2 cycles. For the systemic venous group (controlgroup), gemcitabine and 5-fluorouracil were infused through a peripheral vein, a dose of 1000 mg/m2 gemcitabinebeing administrated over 30 min on days 1 and 8 of a 4-week cycle for 2 cycles, and a dose of 600 mg/m25-fluorouracil was infused on days 1~5 of a 4-week cycle for 2 cycles. The effectiveness and safety were evaluatedafter 2 cyclesaccording to WHO criteria. Results:The objective effective rate in transarterial group was 33.3%versus 25% in the systemic group, the difference not being significant (P=0.626). Clinical benefit rates(CBR) inthe transarterial and systemic groups were 83.3% and 58.3%, respectively (P=0.014). The means and mediansfor survival time in transarterial group were higher than those of the systemic group (P < 0.005). at the sametime, the adverse effects did not significantly differ between the two groups (P > 0.05). Conclusion: Continuoustransarterial infusion chemotherapy with gemcitabine and 5-fluorouracil could improve clinical benefit rate andsurvival time of patients with advanced pancreatic carcinoma, compared with systemic venous chemotherapy.Since adverse effects were limited in the transarterial group, the regimen of continuous transarterial infusionchemotherapy can be used more extensively in clinical practice. A CT and MRI conventional sequence can beused for efficacy evaluation after chemotherapy in pancreatic carcinoma.
