动脉持续灌注化疗与静脉全身化疗治疗中晚期胰腺癌的疗效分析

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 continu-ous 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 con-tinuous transarterial infusion chemotherapy, 26 were treated with systemic venous chemotherapy, and curative effective-ness 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.     

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.     

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.

The incidence of complications in group1 was 47.0%. Three patients died of complications after radical hysterectomy. The incidence of complications in group 2 was 75.6%. CONCLUSION Elderly patients with stage I or II cervical carcinoma should receive an operation if possible. In addition they should receive adjuvant treatments according to their personal conditions, and be treated with appropriate adjuvant chemo-and/or radiotherapy.     

三维放疗联合顺铂同期化疗局部晚期宫颈癌疗效分析

Objective To analyze the therapeutic efficacy and treatment related toxicities for patients with locally advanced cervical cancer treated with three-dimensional conformal radiotherapy (3DCRT) combined with concurrent chemotherapy. Methods From January 2007 to February 2008, 181 patients with stage ⅡA-ⅣA cervical cancer were retrospectively analyzed. All patients were treated with CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent weekly cisplatin-based chemotherapy. The median age was 50 years (range, 32 to 82 years). The overall survival ( OS), disease-free survival (DFS) and local control (LC) rates were calcalated by Kaplan-Meier method and the difference was compared using Log-rank test. The treatment related toxicities were evaluated according to Radiotherapy Oncology Group (RTOG) criteria. Results With a median follow-up time of 34 months and following rate of 92. 2%, the 3-year OS, DFS and LC rates were 73.4%, 70. 4% and 91.3%,respectively. The 3-year OS rate was 66. 9% for patients with tumor diameter ≥4 cm and 86. 4% for those with tumor diameter ＜4 cm( χ2 =6. 29 ,P =0. 012). The incidences of grade 1 and grade 2 acute toxicities of the lower gastrointestinal tract and the genitourinary system were 40. 0% ,45.0% and 19. 9% ,4. 4%,retrospectively. There were no grade 3 or more acute toxicities. The incidence of grades 3 or 4 late toxicities of the lower gastrointestinal tract was 4. 9%. Conclusions CT-based three-dimensional external beam and 192Ir intracavity radiotherapy combined with concurrent chemotherapy can achieve good therapeutic effects for locally advanced cervical cancer. The acute and late toxicities are significantly reduced compared with historic controls as a result of incorporation of 3DCRT technique.

Objective： To evaluate the clinical effect of transurethral resection of bladder tumor（TUR-BT） combined with internal iliac artery chemotherapy and intravesical instillation therapy for muscle invasive bladder cancer（MIBC）.
Methods： From February 2007 to April 2014, 62 patients with MIBC were treated with TUR-BT combined with intravesical instillation therapy, with or without internal iliac artery chemotherapy, and the chemotherapy regimen is gemcitabine and cisplatin（GC）. The bladder preservation and survival rate as well as cancer-specific survival（CSS） rate and overall survival（OS） rate of the two groups were compared.
Results： Sixty-two patients were followed-up for 26-102 months with an average of 58.4±3.1 months. Recurrence-free survival（RFS） at 2-year for TUR ＋ GC group and TUR group were 77.8% and 53.8%, respectively. Bladder preserved rate（BPR） at 3-year for TUR ＋ GC group and TUR group were 94.4% and 80.8%. CSS rate at 2-year for TUR ＋ GC group and TUR group were 94.4% and 84.6%. The diseasefree survival（DFS） at 1-year for TUR ＋ GC group and TUR group were 83.3% and 61.5%, and 77.8% and 53.8% for the 2nd year. OS at 2-year for TUR ＋ GC group and TUR group were 88.9% and 92.3%.
Conclusions： TUR-BT and intravesical instillation therapy combined with internal iliac artery chemotherapy for MIBC had a better outcome at RFS, BPR and DFS than the treatment without internal iliac artery chemotherapy, and no difference in OS and CSS.     

Clinical study on radiotherapy combined with surgical treatment of 162 patients with cervical cancer

Objective: To compare the 5-year survival rates and complications of internal and external irradiation therapy combined with operation in patients with Ⅱ-Ⅲ period of cervical cancer.Methods: 162 cervical cancer patients after the whole palace resection pelvic lymphadenectomy were divided into three groups, and then accepted radiotherapy.The first group with 91 cases was accepted internal and external irradiation therapy before operation; the second group with 37 cases was given internal irradiation therapy before operation; the third group with 34 cases was given routine postoperative radiotherapy.External irradiation used 60Co irradiation or a linear accelerator, to the whole basin, and the irradiation dose of "B" point in preoperative radiotherapy was 26-30 Gy, in postoperative radiotherapy was 46-50 Gy; intraluminal brachytherapy used 192lr,the dose of "A" point was 5-15 Gy.Results: The 5-year survival rate of preoperative combined radiotherapy group was 78.0%(71/91), preoperative intracavitary radiotherapy group 64.9% (24/37), and postoperative radiotherapy group 35.3% (12/34).Comparing the 5-year survival rates of the preoperative combined and postoperative irradiation groups, there was significant difference (P＜0.05).The major complications were radioactive proctitis and cystitis, the complication incidences of three groups were 35.2% (32/91), 32.4% (12/37), 38.2% (13/34), respectively, and the differences were not statistically significant (P＞0.05).Conclusion: The intraluminal brachytherapy plus external irradiation can significantly increase the 5-year survival rate of patients with Ⅱa-Ⅲa stages, and the incidence of complications was not significant difference.     

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.     

Clinical antiangiogenic effect of recombinant adenovirus-p53 combined with hyperthermia for advanced cancer

Objective： To assess the safety and clinical antiangiogenic effect of recombinant adenovirus-p53 （rAd-p53） combined with hyperthermia plus or not plus radiotherapy in advanced cancer. Methods： Expression of Vascular epithelial growth factor （VEGF） after intratumoral injection of rAd-p53 was assayed by immunohistochemistry （IHC） imaging. Forty-four patients with advanced cancer were enrolled into this clinical study. The patients were intratumorally injected with rAd-p53 （Gendicine） at a dose of 1×1012 vp once a week, with a total of 4-54 （mean 7.7） times. Total of 4-29 （mean 8.5） times of hyperthermia was given to the patients. Among the 44 patients, 30 patients were concurrently added with radiotherapy of a total dose 30-76 Gy/15-38 f/3-8 w （mean 58 Gy）. Results： Before and after intratumoral injection of rAd-p53, the VEGF IHC positive cell scores were 2.80 and 1.50, respectively （P=0.031）. The treatment of rAd-p53 combined with hyperthermia plus or not plus radiotherapy in advanced cancer achieved CR rate of 13.60% （6/44）, and PR rate of 29.6% （13/44）, and thus the effective rate was 43.2%. In addition to 6 patients with CR, 19 patients （19/38, 50.0%） had low density area （LDA） of more than 50% area on CT image within tumor indicating tumor tissue necrosis. Conclusions： Our data indicate that rAd-p53 inhibits VEGF expression and angiogenesis, and promotes tumor necrosis and shrinkage induced by hyperthermia plus or not plus radiotherapy in advanced cancer.

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.
