Weekly cisplatin, epirubicin, and paclitaxel with granulocyte colony-stimulating factor support vs triweekly epirubicin and paclitaxel in locally advanced breast cancer: final analysis of a sicog phase III study

The present study aimed at evaluating whether a weekly cisplatin, epirubicin, and paclitaxel (PET) regimen could increase the pathological complete response (pCR) rate in comparison with a tri-weekly epirubicin and paclitaxel administration in locally advanced breast cancer (LABC) patients. Patients with stage IIIB disease were randomised to receive either 12 weekly cycles of cisplatin 30 mg m(-2), epirubicin 50 mg m(-2), and paclitaxel 120 mg m(-2) (PET) plus granulocyte-colony stimulating factor support, or four cycles of epirubicin 90 mg m(-2)+paclitaxel 175 mg m(-2) (ET) every 3 weeks. Overall, 200 patients (PET/ET=100/100) were included in this study. A pCR in both breast and axilla occurred in 16 (16%) PET patients and in six (6%) ET patients (P=0.02). The higher activity of PET was evident only in ER negative (27.5 vs 5.4%; P=0.026), and in HER/neu positive (31 vs 5%; P=0.037) tumours. The two arms yielded similar pCR rate in ER positive (PET/ET=7.5/7.1%) and HER/neu negative (PET/ET=10/6%) patients. At a 39 months median follow-up, 70 patients showed a progression or relapses (PET, 32 vs ET, 38). Anaemia, mucositis, peripheral neuropathy, and gastrointestinal toxicity were substantially more frequent in the PET arm. The PET weekly regimen is superior to ET in terms of pCR rate in LABC patients with ER negative and/or HER2 positive tumours Mature data in terms of disease-free and overall survival are needed to ascertain whether this approach could improve the prognosis of these subsets of LABC patients.     

A phase II study of multimodality treatment for locally advanced cervical cancer: neoadjuvant carboplatin and paclitaxel followed by radical hysterectomy and adjuvant cisplatin chemoradiation.

BACKGROUND: Our aim was to evaluate the efficacy and safety of neoadjuvant chemotherapy followed by radical hysterectomy and adjuvant radiation concurrent with weekly cisplatin for locally advanced cervical carcinoma. PATIENTS AND METHODS: Forty-three patients staged as IB2-IIIB were treated with three 21-day courses of carboplatin (area under the time-concentration curve 6 mg.min/ml) and paclitaxel at 175 mg/m(2) by 3-h infusion both on day 1 followed by radical type III hysterectomy and adjuvant radiation concurrent with 6-weekly doses of cisplatin at 40 mg/m(2). Response rate, resectability, toxicity and survival were evaluated. RESULTS: From December 2000 to June 2001, 43 patients were recruited. All were evaluated for response and toxicity to neoadjuvant chemotherapy. A total of 129 courses were administered. Clinical responses were seen in 41 patients (95%) [95% confidence interval (CI) 89.2% to 100%] with four (9%) complete and 37 (86%) partial. Forty-one patients underwent surgery (resectability 95%); pathologically complete or near-complete responses were seen in seven (17%) and eight (20%), respectively, positive surgical margins in five (12%), and positive pelvic lymph nodes in eight (20%). Twenty-six patients were scheduled for adjuvant chemoradiation. External radiation was delivered for 42.8 days (range 33-61), with a mean dose of 49.3 Gy (range 46-56), and a median of five cisplatin courses (two to six). The mean dose of brachytherapy was 32 Gy (range 25.5-35.6). Neoadjuvant therapy was well-tolerated with neutropenia grade 3 and 4 in 12% and 3% of the courses, respectively. Toxicity to adjuvant chemoradiation was mainly hematological and gastrointestinal, mostly grades 1/2. A total of 39 patients completed all scheduled treatment. At a median follow-up of 21 months (range 3-26), the projected overall survival in the intention-to-treat analysis was 79% (95% CI 62% to 88%). CONCLUSIONS: The triple modality of neoadjuvant chemotherapy followed by radical hysterectomy and adjuvant radiation concurrent with cisplatin is a highly active treatment for locally advanced cervical carcinoma with acceptable toxicity.     

Paclitaxel, cisplatin, and epirubicin first-line chemotherapy in stage III and IV ovarian carcinoma: long-term results of a phase II study

BACKGROUND: The combination of paclitaxel with cisplatin or carboplatin has become the preferred chemotherapy regimen in the treatment of epithelial ovarian carcinoma. Anthracyclines also have activity in this disease. We conducted a Phase II study by using the combination of paclitaxel, cisplatin, and epirubicin for the treatment of advanced ovarian carcinoma. METHODS: Forty consecutive patients with optimally (n = 7) or suboptimally (n = 33) debulked advanced ovarian carcinoma (International Federation of Gynecology and Obstetrics (FIGO) Stage III or IV) were treated with paclitaxel, 135 mg/m(2), as a 3-hour intravenous infusion, cisplatin 75 mg/m(2) intravenously (i.v.), and epirubicin 50 mg/m(2) i.v. every 3 weeks on an outpatient basis. Granulocyte-colony stimulating factor was administered at a dose of 5 microg/kg/day on Days 5-9. RESULTS: Among 28 patients with measurable disease, 24 (86%%) achieved an objective response including 19 complete and 5 partial responses. Among 18 patients who underwent reassessment laparotomy, pathologic complete response was confirmed in 9 patients. At a minimum follow-up of 40 months, the median overall survival had not been reached whereas the median time to progression for all patients was 18.7 months. The median remission duration for women with measurable disease who responded to treatment was 14 months. The treatment was well tolerated without toxic deaths; the most common toxicity was Grade 3/4 neutropenia that occurred in 30% of patients. Significant neuropathy (Grade 2 or higher) developed in only 8% of patients. CONCLUSIONS: The combination of paclitaxel, cisplatin, and epirubicin is a well tolerated outpatient regimen with significant activity in the treatment of advanced epithelial ovarian carcinoma.     

Cisplatin and escalating doses of paclitaxel and epirubicin in advanced ovarian cancer. A phase I study

PURPOSE: The combination of paclitaxel and cisplatin is considered the standard regimen for advanced ovarian cancer (AOC). A meta-analysis has shown that the incorporation of anthracyclines into first-line chemotherapy might improve long-term survival by 7-10%. We designed a phase I-II study in patients with AOC using a combination of a fixed dose of cisplatin with paclitaxel and epirubicin both given at escalating doses every 3 weeks. The objectives of this study were to determine both the maximum tolerated dose (MTD) and the antitumor activity of this combination. METHODS: Six different dose levels were planned. The starting doses were cisplatin 75 mg/m2, paclitaxel 140 mg/m2, and epirubicin 50 mg/m2. The doses of paclitaxel were escalated in 20-mg/m2 increments, alternating with 20-mg/m2 increments of epirubicin. Ten patients with AOC entered the phase I study. Three patients each were enrolled at level I and level II and four patients at level III, and at each level, 15 courses were administered. Patients received a median of five courses. RESULTS: Nonhematological toxicity was generally mild, except for grade 3 mucositis in one course at levels II and III, and grade 3 vomiting in one course at levels I and III. Hematological toxicities were grade 3-4 neutropenia in 60%, 47% and 60% of courses at levels I, II and III, respectively, and grade 3 anemia in one course at level III. At level III two of four patients developed a dose-limiting toxicity which was grade 4 neutropenia lasting more than 1 week. CONCLUSIONS: The MTD was reached at level II with cisplatin 75 mg/m2, paclitaxel 160 mg/m2, and epirubicin 50 mg/m2. The phase II part of the study is currently ongoing.     

Dose-dense cisplatin/paclitaxel. a well-tolerated and highly effective chemotherapeutic regimen in patients with advanced ovarian cancer

A randomised phase I/II trial with weekly cisplatin 70 mg/m(2) (days 1, 8, 15, 29, 36, 43) in combination with escalating doses of paclitaxel either 4-weekly or weekly was conducted in 49 patients with ovarian cancer; patients were chemotherapy-nai;ve or had a first relapse after platinum-based chemotherapy. Paclitaxel could be safely escalated to 225 mg/m(2) 4-weekly or 100 mg/m(2) weekly, with fatigue as the major adverse event. Myelosuppression, renal toxicity and neurotoxicity were mild to moderate. Pharmacokinetic analysis showed an approximately 2-fold reduction of DNA-adduct formation in leucocytes compared with cisplatin without paclitaxel. No pharmacokinetic interaction was found between paclitaxel and cisplatin. After (re-)induction, additional chemotherapy consisted of conventional paclitaxel/cisplatin, paclitaxel/carboplatin, paclitaxel single agent or carboplatin/cyclophosphamide. The overall response rate was 94% in 17 evaluable chemotherapy-nai;ve patients and 84% in 25 patients with recurrent disease. Median progression-free survival (PFS) was 17 months (chemotherapy-nai;ve: 23 months, recurrent: 11 months) and median overall survival was 41 months (chemotherapy-nai;ve: 48 months, recurrent: 24 months). In conclusion, both cisplatin/paclitaxel regimens showed excellent activity with manageable toxicity in patients with advanced ovarian cancer.     

Paclitaxel, epirubicin and cyclophosphamide combination in first-line treatment of metastatic breast cancer: a dose escalation study

The purpose of this study was to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of combined paclitaxel, epirubicin and cyclophosphamide in patients with metastatic breast cancer. The dose of paclitaxel was planned to be escalated from 150 to 225 mg/m(2)in 25 mg/m(2) steps, while the doses of epirubicin and cyclophosphamide were fixed at 50 and 500 mg/m(2), respectively. Because of DLT, the dose of paclitaxel was maintained at 200 mg/m(2) and the dose of epirubicin was increased to 90 mg/m(2). The MTD was reached at a dose of paclitaxel and epirubicin of 200 and 75 mg/m(2), respectively. DLT were mainly febrile neutropenia and grade 4 neutropenia lasting for > or =7 days. Among the 35 evaluable patients, there were 2 (6%) complete responses and 19 (53%) partial responses for an overall response rate of 59% [95% confidence interval (CI): 41-74%]. The triplet paclitaxel/epirubicin/cyclophosphamide is an effective and well-tolerated combination worthy of further investigation in the treatment of patients with metastatic breast cancer.     

Paclitaxel and cisplatin as first-line therapy in recurrent or advanced squamous cell carcinoma of the cervix: a gynecologic oncology group study.

PURPOSE: On the basis of the activity of paclitaxel as a single agent in chemotherapy-naive squamous cell carcinoma of the cervix in a prior Gynecologic Oncology Group (GOG) trial, a phase II study of paclitaxel and cisplatin as first-line therapy was conducted by the GOG. PATIENTS AND METHODS: Eligibility included squamous cell cancer of the cervix not curable by surgery or radiation, measurable disease, WBC count > or = 3,000/microL, platelet count > or = 100, 000/microL, serum creatinine > or = 2 mg/100 mL, and adequate hepatic function. The starting dose was paclitaxel 135 mg/m(2) infused over 24 hours followed by cisplatin 75 mg/m(2) every 21 days. On the basis of toxicity, a dose escalation of paclitaxel to a maximum dose of 170 mg/m(2)/d was prescribed. RESULTS: Forty-seven patients were enrolled onto this study; 44 patients were assessable for toxicity and 41 for response. Forty (90.9%) had received prior radiation therapy. A median of six courses of chemotherapy was given (range, one to 10 courses). Neutropenia grade 3 (15.9%) and 4 (61.4%) was the most frequent severe adverse effect and was associated with fever in 13 patients (27.7%). Two patients (4.5%) died from neutropenic sepsis. Grade 4 thrombocytopenia occurred in 6.8% of patients. Of 41 assessable patients, five (12.2%) had complete responses and 14 (34.1%) had partial responses for an overall response rate of 46.3% (95% confidence interval, 30.7% to 62.6%). The median progression-free interval, was 5.4+ months (range, 0.3 to 22+ months) with a median survival of 10.0+ months (range, 0.9 to 22. 2 months). Response was more frequent in patients with disease in nonirradiated sites (70% v 23%, P =.008). CONCLUSION: This regimen seems highly active in advanced and recurrent squamous cell carcinoma of the cervix and is currently being evaluated by the GOG in a phase III randomized study comparing the combination of paclitaxel and cisplatin with cisplatin alone.     

Phase III study of TAC and TP regimens as neoadjuvant chemotherapy in patients with triple-negative breast cancer

Objective： This study aimed to compare the efficacy and safety of neoadjuvant chemotherapy with TAC and TP regimens of triple negative breast cancer （TNBC）. Methods： A total of 102 patients with TNBC were confirmed by histopathology. They were divided into TAC group （52 cases） and TP group （50 cases）. Group TAC： Docetaxel 75 mg/m2 or paclitaxel （taxol liposome） 135 mg/m2 on all, pirarubicin 40 mg/m2 or epirubicin 75 mg/m2 on d2, cyclophosphamide 600 mg/m2 on dl; Group TP： Docetaxe175 mg/m2 or paclitaxel （taxol liposome） 135 mg/m2 on dl, cisplatin 30 mg/m2 on d2-d4, with 21 days as a cycle. All patients underwent operation after 2-4 cycles of chemotherapy. The short-term effects and toxic and adverse effects were evaluated. Results： In TAC group, 5 cases （9.6%） had pathological complete release （pCR）, 35 cases （67.3%） partial release （PR）, 9 cases （17.3%） stable disease （SD）, and the response rate （RR） was 76.9%. In TP group, 4 cases （8%） had pCR, 32 cases （64%） PR, 5 cases （10%） SD, and RR was 72%. In 102 patients, 12 patients with tumor progression after 2 cycles of chemotherapy, included 3 cases in TAC group, 9 cases in TP group. In TAC group, 2 cases occurred atrial premature contraction; while 3 cases developed grade 2 renal injury in TP group. In TAC group, grade 3-4 hematologic toxicity and alopecia was significantly higher than that in TP group, but grade 3-4 gastrointestinal reaction rate in TP group was significantly higher than TAC group. Conclusion： TAC and TP regimens all had certain efficacy in the neoadjuvant chemotherapy for TNBC, and the toxicity reactions can be tolerated.     

A phase II trial of paclitaxel and epirubicin in advanced breast cancer

Initial trials of paclitaxel and doxorubicin in advanced breast cancer yielded high response rates but significant cardiac toxicity was observed. In this phase II trial we investigated the efficacy and safety of paclitaxel combined with epirubicin. Patients with advanced breast cancer, performance status 0-2, measurable disease, and a normal left ventricular ejection fraction, who may have received adjuvant chemotherapy were treated with epirubicin 75 mg m(-2) followed by a 3-h infusion of paclitaxel 175 mg m(-2) repeated every 3 weeks. Forty-three eligible patients were treated at six centres. 67% patients received the maximum of six cycles. The response rate was 54% (95% CI 38-69%), 12% CR and 42% PR. Estimated median progression-free survival was 6.9 months (95% CI 5.4-10.0) and estimated median overall survival was 17.9 months (95% CI 14.2-25.7). Four patients had a decrease in the left ventricular ejection fraction (LVEF) of > or =20% of baseline value, and in two patients the LVEF decreased to below the lower limit of normal, but no patient developed clinical evidence of cardiac failure. Grade 4 neutropenia occurred in 56% cycles, but only 4% of cycles were complicated by febrile neutropenia. Grade 3 or 4 non-haematologic toxicity was uncommon. In conclusion, paclitaxel 175 mg m(-2) and epirubicin 75 mg m(-2) is a well tolerated, promising regimen for the treatment of advanced breast cancer.

Role of paclitaxel and cisplatin as the neoadjuvant treatment for locally advanced squamous cell carcinoma of the vulva

Objective

The therapeutic outcomes of patients with advanced vulvar cancer are poor. Multi-modality treatments including concurrent chemoradiation or different regimens of neoadjuvant chemotherapy (NACT), and surgery have been explored to reduce the extent of surgery and morbidity. The present single-institution trial aimed to evaluate the efficacy and toxicity of paclitaxel and cisplatin in locally advanced vulvar cancer.

Methods

From 2002 to 2009, 10 patients with stage III-IV locally advanced squamous cell carcinoma of the vulva were prospectively treated with 3 courses of paclitaxel-ifosfamide-cisplatin or paclitaxel-cisplatin. Nine of them subsequently underwent radical local excision or radical partial vulvectomy and bilateral inguino-femoral lymphadenectomy.

Results

The clinical response rate of all enrolled patients was 80%, whereas the pathological responses included 1 case with complete remission, 2 with persistent carcinoma in situ, and 6 invasive cancer cases with tumor shrinkage of more than 50%. Four patients had positive nodes. Forty percent of patients experienced grade 3-4 bone marrow toxicity, which was successfully managed with granulocyte-colony stimulating factor, even in cases of elderly patients. Median progression-free survival after surgery was 14 months (range, 5 to 44 months). Six of the 7 recurrent cases were local, and 3 of them were treated with salvage surgery while the other 3 received radiation with or without chemotherapy. After a median follow-up period of 40 months (range, 5 to 112 months), 55.5% of patients remained alive with no evidence of disease, including 2 long-term survivors after recurrence at 5 and 9 years.

Conclusion

Based on the high response rate and manageable toxicity, NACT with paclitaxel and cisplatin with or without ifosfamide followed by surgery could be considered as a therapeutic option for locally advanced vulvar cancer.     

Gemcitabine/epirubicin/paclitaxel as neoadjuvant chemotherapy in locally advanced breast cancer: a phase II trial of the NSABP Foundation Research Group

BACKGROUND: This phase II protocol of neoadjuvant chemotherapy with gemcitabine/epirubicin/paclitaxel (GET) was designed to determine the pathologic complete response (pCR) rate in the breast, clinical response rate, disease-free survival, and overall survival at 2 years as well as toxicity in patients with locally advanced breast cancer. This trial also evaluated the feasibility of tissue collection for gene-expression profiling. PATIENTS AND METHODS: Seventy-six women with stage IIB, IIIA, and IIIB breast cancer were entered into this trial. Patients received a maximum of 6 cycles of neoadjuvant GET chemotherapy every 21 days (gemcitabine 1000 mg/m2 intravenously [i.v.] on days 1 and 4, epirubicin 90 mg/m2 i.v. bolus on day 1, and paclitaxel 175 mg/m2 i.v. on day 1). After chemotherapy, patients underwent surgery and were assessed for pathologic response. RESULTS: The pCR rate among the 74 patients evaluable for efficacy was 23% (95% CI, 14%-34.2%). Adverse events among the 76 patients evaluable for toxicity included anemia requiring transfusion (14.5%), infection with grade 3/4 neutropenia (10.5%), febrile neutropenia (7.9%), and platelet transfusion (6.6%). Infectious complications occurred in 24 patients (31.6%), of whom 18.4% were in the setting of neutropenia. High-quality RNA and successful probe synthesis were obtained from all pretreatment core biopsy specimens that contained tumor cells (n=66; 88%). CONCLUSION: Neoadjuvant GET chemotherapy is an active regimen but with substantial toxicity. Tissue collection for gene-expression profiling is feasible in a multi-institutional setting.     

Tailored preoperative treatment of locally advanced triple negative (hormone receptor negative and HER2 negative) breast cancer with epirubicin, cisplatin, and infusional fluorouracil followed by weekly paclitaxel

BACKGROUND: No specific treatment guidelines are available for triple-negative breast cancers, defined by a lack of expression of estrogen (ER), progesterone (PgR), and HER2 receptors. PATIENTS AND METHODS: We investigated in patients with T2-T3 N0-3 ER, PgR <10% and HER2 negative breast cancers the activity both in terms of pathological (pCR) and objective responses of four courses of cisplatin containing chemotherapy (ECF, epirubicin, cisplatin, and fluorouracil as continuous infusion) followed by three courses of weekly paclitaxel. Adjuvant metronomic chemotherapy including cyclophosphamide and methotrexate for 4-6 months was administered. RESULTS: Thirty patients are evaluable. Median age was 41 years (28-64 years). Twenty-three of 25 evaluable tumors stained positively for epidermal growth factor receptor. An objective response, either complete and partial, was observed in 26 patients (86, 95% CI 69.3-96.2%). and a pCR was obtained in 12 patients (40, 95% CI 22.7-59.4%). Two patients progressed during paclitaxel. Negative axillary nodes were found in 80% (95% CI 61.4-92.3%) of patients at surgery. Twenty-six patients (86, 95% CI 61.4-92.3%) underwent breast conserving surgery. Grade >2 non-hematological toxicity was observed in three and two patients during ECF and paclitaxel, respectively. The 2-year disease free survival (DFS) was 87.5% (95% CI 74.7-100%). No significant correlation was observed between EGFR staining and either pCR or DFS. CONCLUSIONS: Preoperative cisplatin containing chemotherapy followed by paclitaxel induced an high pCR rate in a population of triple-negative breast cancer. The impact of this schedule on long-term outcome should be investigated in larger series.

Phase III study comparing cisplatin plus fluorouracil to paclitaxel, cisplatin, and fluorouracil induction chemotherapy followed by chemoradiotherapy in locally advanced head and neck cancer.

PURPOSE: To compare the antitumor activity and toxicity of the two induction chemotherapy treatments of paclitaxel, cisplatin, and fluorouracil (FU; PCF) versus standard cisplatin and FU (CF), both followed by chemoradiotherapy (CRT), in locally advanced head and neck cancer (HNC). PATIENTS AND METHODS: Eligibility criteria included biopsy-proven, previously untreated, stage III or IV locally advanced HNC. Patients received either CF (cisplatin 100 mg/m2 on day 1 plus FU 1000 [corrected] mg/m2 continuous infusion on days 1 through 5) or PCF (paclitaxel 175 mg/m2 on day 1, cisplatin 100 mg/m2 on day 2, and FU 500 mg/m2 continuous infusion on days 2 through 6); both regimens were administered for three cycles every 21 days. Patients with complete response (CR) or partial response of greater than 80% in primary tumor received additional CRT (cisplatin 100 mg/m2 on days 1, 22, and 43 plus 70 Gy). RESULTS: A total of 382 eligible patients were randomly assigned to CF (n = 193) or PCF (n = 189). The CR rate was 14% in the CF arm v 33% in the PCF arm (P < .001). Median time to treatment failure was 12 months in the CF arm compared with 20 months in the PCF arm (log-rank test, P = .006; Tarone-Ware, P = .003). PCF patients had a trend to longer overall survival (OS; 37 months in CF arm v 43 months in PCF arm; log-rank test, P = .06; Tarone-Ware, P = .03). This difference was more evident in patients with unresectable disease (OS: 26 months in CF arm v 36 months in PCF arm; log-rank test, P = .04; Tarone-Ware, P = .03). CF patients had a higher occurrence of grade 2 to 4 mucositis than PCF patients (53% v 16%, respectively; P < .001). CONCLUSION: Induction chemotherapy with PCF was better tolerated and resulted in a higher CR rate than CF. However, new trials that compare induction chemotherapy plus CRT versus CRT alone are needed to better define the role of neoadjuvant treatment.     

Increased feasibility of weekly epirubicin and paclitaxel as neoadjuvant chemotherapy for locally advanced breast carcinoma

BACKGROUND: Primary systemic therapy (PST) with a combination of epirubicin and paclitaxel achieves high response rates in locally advanced breast cancer (LABC), but considerable toxicity occurs and the patient's compliance is poor. In this open-label phase II trial toxicity of a weekly administration schedule was evaluated. PATIENTS AND METHODS: On days 1 and 8 of each 3-week cycle, 45 patients with non-inflammatory breast cancer received epirubicin (35 mg/m(2), intravenous bolus) followed by paclitaxel (80 mg/m(2) in 500 ml of normal saline infused over 3 h) for 3 cycles. Surgery was done 2 weeks after primary chemotherapy, followed by another 6 cycles of adjuvant CEF (cyclophosphamide 500 mg/m(2), epirubicin 70 mg/m(2), 5-fluorouracil 500 mg/m(2)) chemotherapy. RESULTS: The median tumor size before and after PST was 6.0 and 2.0 cm, respectively. The clinical response rate was 96%, including 24% complete remission; 5 patients (11%) achieved pathologically complete response (pCR) including 3 patients with carcinoma in situ. Only 5 (11%) patients underwent breast conserving surgery although there were 15 patients suitable. Axillary nodes were negative in 16 (36%) of the 45 patients. Febrile neutropenia was found in 1 patient. There was no severe cardiac toxicity or serious adverse events. CONCLUSIONS: PST with weekly epirubicin and paclitaxel was an effective and well-tolerated combination for LABC, although only few patients underwent breast conserving surgery.     

Randomized comparison of cisplatin plus epirubicin or doxorubicin for advanced epithelial ovarian carcinoma. A multicenter trial.

Stage III and IV epithelial ovarian cancer patients were prospectively randomized to receive eight courses of 60 mg/m2 of cisplatin plus either 75 mg/m2 of epirubicin (62 patients) or 60 mg/m2 of doxorubicin (54 patients). Clinical response rates for cisplatin/epirubicin of 42% [15% complete response (CR) and 27% partial response (PR)] and for cisplatin/doxorubicin of 55% (24% CR and 31% PR) were not statistically different (p = 0.14). The negative second look rate was 35% (10/29) for cisplatin/doxorubicin and 17% (5/30) for cisplatin/epirubicin (p = 0.12). The progression-free interval for cisplatin/epirubicin (13 months) was not statistically different (p = 0.09) from that for cisplatin/doxorubicin (19 months). The median survivals for cisplatin/epirubicin (756 days) and cisplatin/doxorubicin (739 days) were similar (p = 0.70). Cardiotoxicity was greater for the cisplatin/doxorubicin group (p = 0.0003). With similar survival and less cardiotoxicity, the cisplatin/epirubicin regimen had the more favorable therapeutic index.     

紫杉醇联合顺铂治疗晚期食管鳞癌

目的研究紫杉醇联合顺铂治疗晚期食管癌的疗效和毒副反应。方法30例晚期食管磷癌患者中,27例为初次化疗患者,3例患者曾接受术后辅助化疗。中位年龄58岁。紫杉醇175mg／m^2,d1,静脉滴注3h;顺铂40mg/m^2,d2,d3;21d为1个周期。结果30例患者共完成89个化疗周期。在可评价疗效的27例患者中,完全缓解5例(18．5％),部分缓解11例(40．7％),有效率为59．3％。中位疾病进展时间为5．0个月,中位生存时间9．7个月。可评价毒副反应28例,其主要的毒副反应为脱发,有5例(17．9％)患者出现Ⅲ-Ⅳ度中性粒细胞降低。结论紫杉醇联合顺铂对晚期食管癌疗效肯定,可以考虑作为治疗晚期食管癌的主要治疗方案。
