BACKGROUND: Previous studies suggest that the combination of docetaxel and capecitabine are worthy of further testing in patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. We therefore undertook this phase II study to test this combination in a multi-institutional, first-line clinical trial. PATIENTS AND METHODS: Forty-four eligible patients with histologic or cytologic confirmation of the above malignancy were recruited. The cohort had Eastern Cooperative Oncology Group performance scores of 0, 1 and 2 in 59%, 39% and 2% of patients, respectively. Median age was 57 years (range 32-77 years). Adequate organ function was a requirement for study entry. All patients were prescribed docetaxel 75 mg/m2 intravenously on day 1 and capecitabine 825 mg/m2 orally twice a day on days 1-14 of a 21-day cycle. RESULTS: The tumor response rate was 39% [95% confidence interval (CI) 23% to 55%]. There were two complete responses and the rest were partial. Median survival was 9.4 months (95% CI 6.3-10.7 months) and median time-to-tumor progression was 4.2 months (95% CI 3.6-5.6 months). There was one treatment-related death from a myocardial infarction and dysrhythmia. Commonly occurring grade 3 adverse events included neutropenia (11 patients), infection (five patients), constipation (three patients), thrombosis (three patients), dyspnea (three patients) and hand-foot syndrome (three patients). In addition, 24/45 patients developed grade 4 neutropenia. CONCLUSIONS: The regimen docetaxel and capecitabine shows activity in patients with metastatic adenocarcinoma of the stomach and gastroesophageal junction. This regimen merits further study. 相似文献

BACKGROUND: PS-341 is a proteasome inhibitor with preclinical activity in pancreatic cancer tumor models and synergistic activity with gemcitabine. This randomized phase II study determined the tumor response rate (RR) for PS-341 alone and the 6-month survival and RR for the combination of gemcitabine and PS-341 in patients with metastatic pancreatic adenocarcinoma. PATIENTS AND METHODS: Patients were randomized to receive 3-week cycles of either arm A: PS-341 1.5 mg/m(2) i.v. bolus (over 3--5 s) on days 1, 4, 8 and 11 or arm B: PS-341 1.0 mg/m(2) (same as arm A otherwise) plus gemcitabine 1,000 mg/m(2) i.v. on days 1 and 8. Patients progressing on arm A were allowed to receive arm B treatment. RESULTS: Arm A: 42 evaluable patients were enrolled with a confirmed RR of 0% (95% CI 0% to 8%), median survival of 2.5 months (95% CI 2.0-3.3), and median time to progression (TTP) of 1.2 months (95% CI 1.1--1.3). Twelve of 43 evaluable patients (28%) experienced at least one grade 4+ AE. Arm B: 39 evaluable patients yielded a 6-month survival rate of 41% (16/39, 95% CI 29.8% to 67.0%), median survival of 4.8 months (95% CI 2.4--7.4), median TTP of 2.4 months (95% CI 1.5--3.1), and confirmed RR of 10% (4 partial responses/0 complete responses, 95% CI 3% to 24%). Eleven of 43 evaluable patients (26%) experienced at least one grade 4+ AE. One patient had grade 5 hypotension. CONCLUSION: The use of PS-341 alone or in combination with gemcitabine did not result in an overall survival and RR better than that expected for gemcitabine alone. Based on the lack of efficacy and the toxicity seen in our trial, there does not appear to be a role for PS-341 in pancreatic adenocarcinoma with either of the schedules used in this trial. 相似文献

Background:There were approximately 12,500 cases of esophageal carcinoma diagnosed in the US in 1992 and 12,200 deaths. The impact of chemotherapy on patients with metastatic disease is marginal with a median survival of only five months. Gemcitabine (LY188011,2,2,–difluorodeoxycytidine: dFdC), an analog of cytosine arabinoside (ara-C), is a pyrimidine antimetabolite. Gemcitabine has shown interesting clinical activity in initial phase II clinical trials in a variety of malignancies, including the aerodigestive malignancies, squamous-cell carcinoma of the head/neck and both non-small-cell and small-cell lung cancer.
Patients and methods:A total of 21 patients with chemotherapy-naïve metastatic esophageal carcinoma were entered. Nineteen patients were evaluable for toxicity and seventeen patients were evaluable for response. Gemcitabine was administered intravenously at 1250 mg/m2 over 30–60 minutes on days 1, 8, and 15 followed by 1 week of rest. This four-week schedule defined a cycle of treatment. Patients may have received a maximum of six cycles.
Results:Gemcitabine was well tolerated with minimal non-hematologic toxicity and grade 3–4 anemia, granulocytopenia, and thrombocytopenia occurring in 10.5%, 21%, and 0% of patients, respectively. No responses were seen in the seventeen evaluable patients.
Conclusions:At the dose and schedule studied it would appear that gemcitabine has no activity in patients with chemotherapy-naïve esophageal carcinoma. 相似文献

BACKGROUND: This study was performed to determine the efficacy of gemcitabine and oxaliplatin in patients with advanced or metastatic pancreatic adenocarcinoma (ACA). PATIENTS AND METHODS: Pancreatic ACA patients with previously untreated advanced or metastatic disease were enrolled in a phase II study of gemcitabine and oxaliplatin. Oxaliplatin was given i.v. on day 1 and gemcitabine i.v. on days 1 and 8 of a 3-week cycle. The primary end point of the trial was 6-month survival. Secondary end points included response rate, overall survival, median time to progression and toxicity. RESULTS: A total of 47 patients were enrolled, 46 of whom were evaluable. Of those patients assessed for the primary end point 50% lived for > or =6 months. The median time to progression was 4.53 months. Five confirmed responses were seen with a median duration of response of 2.7 months. Overall, the treatment was well tolerated. However, one patient died as a result of treatment-related hemolytic uremic syndrome. CONCLUSIONS: Gemcitabine and oxaliplatin, at doses of 1000 mg/m(2) and 100 mg/m(2), respectively, showed moderate activity in patients with pancreatic ACA. Based on the results of this study further evaluation of this combination is warranted. 相似文献

Purpose. The incidence of adenocarcinoma of the lower third of the esophagus, esophagogastric junction, and gastric cardia has been rising in the face of limited treatment options for patients with metastatic disease. With the emergence of data to suggest that single agent docetaxel and irinotecan carry antineoplastic effects in this setting, we determined the response rate of these agents when given in combination. Patients and Methods. Forty-six patients with metastatic adenocarcinoma of the lower third of the esophagus, esophagogastric junction, and gastric cardia were evaluated. Patients received docetaxel 50 mg/m2/d and irinotecan 130 mg/m2/d intravenously at 21-d intervals with a tumor assessment after 2 cycles. Because of unacceptable toxicity among the first 13 patients, dosing was reduced to docetaxel 40 mg/m2/d and irinotecan 100 mg/m2/d intravenously at 21-d intervals. Results. The response rate for the entire cohort was 26% (95% confidence interval: 14%, 41%) with 12 confirmed partial responses. Five of these 12 responses were observed in patients treated at the higher chemotherapy dose. However, because 8 of 13 patients suffered grade 4 neutropenia and fevers, a dose reduction was incorporated into the protocol, and the remainder of the cohort was treated at the lower dose. All except 4 of the 15 observed grade 4 toxicities occurred at the higher dose, and these toxicities included nausea and vomiting, dyspnea, hypotension, dysrhythmias, and diarrhea in addition to neutropenia and fevers. There were no grade 5 toxicities. The median survival for the entire cohort was 7.3 mo. Conclusion. The combination of docetaxel and irinotecan provides modest antineoplastic activity among patients with adenocarcinoma of the esophagus, esophagogastric junction, and gastric cardia. Doses of docetaxel 40 mg/m2/d and irinotecan 100 mg/m2/d at 21-d intervals provide an acceptable safety profile, but higher doses appear to result in unacceptable toxicity. 相似文献

This phase II study was designed to evaluate the activity and safety of a combination of irinotecan, docetaxel and oxaliplatin in metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. Forty patients with measurable distant metastasis received irinotecan 150 mg m(-2) and docetaxel 60 mg m(-2) on day 1, and oxaliplatin 85 mg m(-2) on day 2. Cycles were repeated every 3 weeks. The primary end point was to demonstrate a 50% improvement in time-to-progression (TTP) over historical controls. All patients were evaluable. Median TTP was 6.5 months (95% confidence interval (CI) 5.6-7.4), the overall response rate was 50% (95% CI 35-65%) and the median overall survival was 11.5 months (95% CI 8.7-14.3). Grade 3/4 neutropaenia occurred in 47.5% of patients. There were four episodes of febrile neutropaenia in three patients. Other non-haematological grade 3 toxicities included diarrhoea in four patients (10%), vomiting in three patients (7.5%) and mucositis in two patients (5%). The irinotecan, docetaxel and oxaliplatin combination chemotherapy is an active and well-tolerated novel regimen for treating metastatic gastric or GEJ adenocarcinoma and deserves further evaluation in randomised trials and in combination with molecular targeting agents. 相似文献

We investigated 2-weekly intravenous irinotecan combined with oral capecitabine in patients with advanced gastroesophageal adenocarcinoma. In phase I, doses were escalated in chemotherapy naïve or pretreated patients to establish maximum tolerated doses (MTD). In phase II, patients were treated at MTD as first-line therapy with the primary end point of RECIST response. Dose levels in phase I were as follows: Level 1: irinotecan 150 mg m−2 on day 1; capecitabine 850 mg m−2 12-hourly on days 1–9. Level 2: as level 1 but capecitabine 1000 mg m−2. Level 3: as level 2 but irinotecan 180 mg m−2. Level 4: as level 3 but capecitabine 1250 mg m−2. In phase I, 21 patients were entered. Maximum tolerated dose was level 3. Dose-limiting toxicities were lethargy, diarrhoea, vomiting and mucositis. In phase II, 31 patients were entered at level 3. During the first six cycles, 13 of these patients underwent dose reduction and three patients stopped treatment for toxicity. A further six patients stopped for progressive disease. The commonest grade 3–4 toxicities were lethargy (20%), diarrhoea (17%), nausea (10%) and anorexia (10%). There were no treatment-related deaths. The response rate was 32% (95% CI 16–52%). Median overall survival was 10 months. This regimen is active in gastroesophageal adenocarcinoma. However, using the MTD defined in phase I, fewer than 50% patients tolerated six cycles without modification in phase II; therefore, modification of these doses is recommended for further study. 相似文献

PURPOSE: A phase I study was performed to determine the maximal tolerated dose, recommended doses (RDs), safety and efficacy of oral vinorelbine when combined with capecitabine in an all-oral chemotherapy regimen in patients with metastatic breast cancer (MBC), with pharmacokinetic blood sampling to investigate potential drug-drug interactions. PATIENTS AND METHODS: Forty-four patients with MBC received as first- or second-line chemotherapy, oral vinorelbine at a dose of 60 or 80 mg/m2 on days 1 and 8 (and 15) with escalating doses of capecitabine from 1650 to 2500 mg/m2/day days 1-14 every 3 or 4 weeks. Three schedules were tested: day 1, day 8 and weekly regimens of oral vinorelbine with a 14-day course of capecitabine every 3 weeks; and a days 1 and 8 regimen of oral vinorelbine with a 14-day course of capecitabine every 4 weeks. RESULTS: With oral vinorelbine at 60 mg/m2, the RDs were established as oral vinorelbine 60 mg/m2 on days 1 and 8 plus capecitabine 2250 mg/m2/day days 1-14 and oral vinorelbine 60 mg/m2/week plus capecitabine 2000 mg/m2/day days 1-14. With oral vinorelbine at 80 mg/m2, the RD was oral vinorelbine 80 mg/m2 on days 1 and 8 plus capecitabine 2000 mg/m2/day days 1-14. Neutropenia was the main dose-limiting toxicity of the combination; it was reported in 40 patients (90.9%), with grade 3 in 14 patients (31.8%) and 6.2% of cycles, and grade 4 in 12 patients (27.3%) and 4.3% of cycles. Complications were rare with only three patients experiencing febrile neutropenia (one episode each). The most frequent non-haematological toxicity was gastrointestinal; however, the incidence of grade 3 was low, with no episode of grade 4. Hand-foot syndrome was reported in 14 patients (31.8%) and 22.6% of cycles, with grade 2 in two patients (4.5%) and 1.2% of cycles (two episodes each). No episode of grade 3 was observed. Objective responses were reported in 18 patients (three complete responses and 15 partial responses), yielding a response rate of 40.9% in the intention-to-treat population according to the investigator assessment. Results from the pharmacokinetic study demonstrated the absence of mutual pharmacokinetic interactions when both drugs were co-administered. CONCLUSIONS: The combination of oral vinorelbine and capecitabine is safe and easy to administer in an outpatient setting. This all-oral combination chemotherapy may offer a good alternative to the intravenous route for patients with MBC. Based on these promising results, a phase II study has started using oral vinorelbine 60 mg/m2/week with capecitabine 2000 mg/m2/day days 1-14 every 3 weeks as first-line chemotherapy in patients with MBC. 相似文献

The combination of intravenous (i.v.) vinorelbine and epirubicin is highly active in the treatment of metastatic breast cancer (MBC). In an effort to improve patient convenience, we investigated a regimen alternating i.v. and oral vinorelbine in combination with epirubicin as first-line chemotherapy of patients with MBC. In all, 49 patients with MBC received, as first-line treatment, a combination regimen consisting of i.v. vinorelbine 25 mg m(-2) plus epirubicin 90 mg m(-2) given on day 1, and oral vinorelbine 60 mg m(-2) on day 8 (or day 15 if neutrophils <1500 mm(-3)) every 3 weeks, in an open-label, multicentre phase II study. Treatment was to be repeated for a maximum of six cycles. The study population had a median age of 55 years, half of the patients had received prior adjuvant chemotherapy and 86% presented a visceral involvement. In all, 25 responses were documented and validated by an independent panel review, yielding response rates of 51% (95% CI: 36-66) in the 49 enrolled patients and 54.5% (95% CI: 39-70) in the 44 evaluable patients. Median durations of progression-free survival and survival were 8 and 20 months, respectively. Neutropenia was the main dose-limiting toxicity, but complications were uncommon, four patients having experienced febrile neutropenia and six having developed neutropenic infection. Other frequently reported adverse events included stomatitis, nausea and vomiting, which were rarely severe. No toxic death was reported. Among patients who received six cycles, global score of quality of life remained stable. This regimen alternating oral and i.v. vinorelbine in combination with epirubicin is effective and safe. Oral vinorelbine on day 8 offers greater convenience to the patient, and decreases the need for i.v. injection and reduces time spent in hospital. Therefore, oral vinorelbine is a convenient alternative to the i.v. form in combination regimens commonly used to treat MBC. 相似文献

PURPOSE: Surgical resection of liver-only metastases from colorectal cancer has undergone extensive evaluation and review. The use of neoadjuvant chemotherapy to improve the likelihood of resection in disease that is not optimally resectable has not been as well studied. PATIENTS AND METHODS: Patients with liver-only metastases from colorectal cancer deemed not optimally resectable by a surgeon with expertise in liver surgery received fluorouracil, leucovorin, and oxaliplatin (FOLFOX4). Patients were periodically reassessed for resectability. Surgical response was classified as completely resectable (S-CR), partially resectable (S-PR), or unresectable (S-UR). Study design specified the accrual of 39 patients, with two or more S-CRs considered evidence of promising activity with respect to increasing the S-CR rate. RESULTS: Forty-two of 44 patients were assessable for this analysis. Twenty-five patients (60%) had tumor reduction by serial imaging. Seventeen patients (40%) underwent surgery (S-CR, n = 14; S-PR, n = 1; and S-UR, n = 2) after a median of 6 months of chemotherapy. With a median postsurgical follow-up of 22 months (range, 13 to 32 months), 11 recurrences have occurred in the 15 S-CR and S-PR patients. Median survival time was 26 months. CONCLUSION: Our data suggest that FOLFOX4 has a high response rate (complete response, partial response, or reduction) in patients with liver-only metastases from colorectal cancer, allowing for successful resection of disease in a portion of patients initially not judged to be optimally resectable. However, a high recurrence rate after surgery was observed, which, in 73% of patients, involved the liver. Further trials are indicated based on the promising results observed in this trial. 相似文献

Background:
This multicentre, international phase II trial evaluated the efficacy and safety profile of a first-line combination of oral vinorelbine plus capecitabine for women with metastatic breast cancer (MBC).Methods:
Patients with measurable, HER2-negative disease received, as a first line in metastatic setting, 3-weekly cycles of oral vinorelbine 80 mg m−2 (after a first cycle at 60) on day 1 and day 8, plus capecitabine 1000 mg m−2 (750 if ⩾65 years of age) twice daily, on days 1–14. Treatment was continued until progression or unacceptable toxicity.Results:
A total of 55 patients were enrolled and 54 were treated (median age: 58.5 years). Most (78%) had visceral involvement and 63% had received earlier (neo)adjuvant chemotherapy. The objective response rate (RECIST) in 49 evaluable patients was 51% (95% confidence interval (CI), 36–66), including complete response in 4%. The clinical benefit rate (response or stable disease for ⩾6 months) was 63% (95% CI, 48–77). The median duration of response was 7.2 months (95% CI, 6.4–10.2). After a median follow-up of 41 months, median progression-free survival was 8.4 months (95% CI, 5.8–9.7) and median overall survival was 29.2 months (95% CI, 18.2–40.1). Treatment-related adverse events were manageable, the main grade 3–4 toxicity was neutropaenia (49%); two patients experienced febrile neutropaenia and three patients had a neutropaenic infection (including one septic death). A particularly low rate of alopaecia was observed.Conclusion:
These results show that the all-oral combination of oral vinorelbine and capecitabine is an effective and well-tolerated first-line regimen for MBC. 相似文献13.

BACKGROUND: To evaluate the efficacy and safety of the combination of cisplatin and vinorelbine in metastatic breast cancer. PATIENTS AND METHODS: Cisplatin (80 mg/m(2) day 1) and vinorelbine (25 mg/m(2) days 1 and 8) were administrated every 3 weeks to 52 patients (mean age 57 years; range 35-75 years) with metastatic breast cancer. Thirty-two patients were previously untreated for metastatic disease. Treatment was repeated for a maximum of six cycles. RESULTS: Objective responses were obtained in 27 patients (52.9%; complete response 9.8%). The response rate was similar in pretreated and untreated patients (50% and 54.7%, respectively; P = 0.7). ECOG performance status was good (grade 0 or 1) in 55.7% of patients at baseline assessment and in 90.3% at the end of treatment (P = 0.0001). Median time to progression was 8.5 months (8.5 months in first-line and 8.7 months in second-line patients). Median survival was 16.6 months (21.2 months in first-line and 16.1 months in second-line patients). Grade 3/4 toxicity included neutropenia (44% in first-line, 60% in second-line patients), nausea (17.3%), anemia (17%), asthenia (3.8%) and thrombocytopenia (1.9%). There were no cases of febrile neutropenia or treatment-related deaths. Alopecia did not develop in any of the patients. CONCLUSIONS: Cisplatin plus vinorelbine is active and tolerable in metastatic breast cancer, in untreated and pretreated patients. 相似文献

BACKGROUND: Gemcitabine is an active antitumor agent in the treatment of advanced pancreatic cancer, and has shown potential synergistic activity with the oral fluoropyrimidine capecitabine in previous phase I/II trials. Based on this background and in order to define the therapeutic potential and tolerance of this combination more precisely, the present randomized multicenter phase II trial was initiated. PATIENTS AND METHODS: We prospectively randomized 83 patients to treatment with biweekly gemcitabine 2,200 mg/m(2) given as a 30 min intravenous infusion on day 1, or the same treatment plus oral capecitabine 2,500 mg/m(2) given from days 1 to 7. In both arms, chemotherapy was administered for a duration of 6 months unless there was prior evidence of progressive disease. The efficacy of the two treatment arms was evaluated according to standard criteria, i.e. objective response, progression-free survival (PFS) and overall survival (OS), as well as by analysis of clinical benefit response. RESULTS: The overall objective response rate among the 42 patients treated with gemcitabine alone was 14% compared with 7/41 (17%) among those treated with the combination arm. Similar to response rates, there was no apparent difference between the two groups in terms of median PFS (4.0 versus 5.1 months) and median OS (8.2 versus 9.5 months) in the gemcitabine and combination arm, respectively. Of 61 patients with tumor-related symptoms, who were considered evaluable for clinical benefit response, 10/30 (33%) and 15/31 (48.4%) experienced significant palliation in the gemcitabine and combination arm, respectively. Chemotherapy was well tolerated in both arms with only four versus six patients experiencing WHO grade 3 symptoms. Apart from the occurrence of hand-foot syndrome in 10 patients, no major increase in incidence and/or degree of adverse reactions was noted in the combination arm. CONCLUSIONS: Results of this trial suggest a fairly good therapeutic index for the combination of biweekly high-dose gemcitabine and capecitabine for the treatment of advanced pancreatic cancer. Despite a somewhat superior clinical benefit response rate, no advantage over single-agent gemcitabine, however, was noted in terms of objective efficacy parameters. 相似文献

PURPOSE: Gemcitabine remains the standard therapy for metastatic pancreatic adenocarcinoma (ACA), but has limited activity. ISIS-2503 is an antisense compound directed against H-ras with preclinical activity against pancreatic ACA in tumor models. The combination of ISIS-2503 and gemcitabine has been evaluated in a prior phase I study. METHODS: Patients with metastatic or locally advanced pancreatic ACA not amenable to surgery or local radiation received gemcitabine 1,000 mg/m(2) intravenously over 30 minutes on days 1 and 8 and ISIS-2503 6 mg/kg/d as a continuous intravenous infusion over 14 days of an every-3-weeks cycle. Responses were monitored by radiologic imaging every 6 weeks. RESULTS: Forty-eight eligible patients were enrolled, 43 with metastatic disease. Median follow-up was 12.6 months (range, 2.2 to 16.8 months) for living patients. A median of four cycles of treatment was given (range, 1 to 18 cycles). All patients were assessable for response and toxicity. The 6-month survival percentage was 57.5% (95% CI, 44.9% to 73.5%) and the median survival was 6.6 months. The response rate was 10.4% (one complete response, four partial responses). Clinically significant toxicity was limited except for one fatal pulmonary embolism. CONCLUSION: This study shows a promising response rate to the combination of gemcitabine and ISIS-2503 in patients with pancreatic ACA. The observed 6-month survival rate in these patients met our protocol-defined criteria for success. This regimen is tolerable, but is of unclear benefit. Additional studies evaluating the role of gemcitabine and ISIS-2503 in the treatment of pancreatic ACA should be considered. 相似文献

Background: Capecitabine and i.v. vinorelbine are both active in metastatic breast cancer with non‐overlapping toxicities. This study examined the efficacy and safety of the combination of these agents in patients with pretreated metastatic breast cancer. Methods: Patients previously treated for breast cancer, maximum of one prior metastatic regimen, received capecitabine 1000 mg/m2 b.d. for days 1–14 and vinorelbine 25 mg/m2 i.v. days 1 and 8 every 21 days. All patients had measurable disease and adequate baseline organ function. The primary endpoint was response and secondary endpoints time to progression, duration of response, survival and safety. Results: Twenty‐two patients (median age 56 years) received a median of six cycles. All patients had received anthracyclines and 64% taxanes. Objective responses were seen in 7/21 (33%, 95% confidence interval [CI] 18–57%), with two complete responses; stable disease was seen in 5/21 (24%, 95% CI 8–42%). Median duration of response was 6.9 months (95% CI 4.7–13.1), time to progression was 5.8 months (95% CI 2.8–6.8) and survival was 13.5 months (95% CI 6.9–19.9). The median dose intensity of vinorelbine was 75% of the intended dose and of capecitabine 85% of intended dose. The main toxicity was myelosuppression including 16 episodes of G3–4 neutropenia in 11 patients (50%). Other toxicities were generally mild to moderate. Conclusion: The combination of capecitabine and i.v. vinorelbine is active and well tolerated in patients with pretreated metastatic breast cancer. The recent availability of oral vinorelbine provides an opportunity to explore a fully oral combination. 相似文献

Background There is no standard first-line therapy for advanced gastric and gastroesophageal junction (GEJ) adenocarcinoma and the prognosis
remains poor. Our institution conducted a phase I study of oxaliplatin, irinotecan, and capecitabine given in a novel, weekly
schedule. The regimen was tolerated; pharmacodynamic studies revealed no drug interactions, and there was one confirmed response
in a gastric cancer patient. We performed a phase II trial in advanced gastric and GEJ adenocarcinoma to determine response
rate and response duration.
Methods This was a multi-center single treatment arm study involving six sites. Only prior adjuvant therapy was allowed. Patients
had ECOG performance status of 0–2, adequate organ function, and were able to tolerate oral medications. All patients received
oxaliplatin 60 mg/m2 intravenously (IV) and irinotecan 50 mg/m2 IV weekly times 4 weeks with a 2-week rest period. Capecitabine 450 mg bid orally was received on days 1 through 5 every
week for 4 weeks, followed by a 2-week rest. Patients were assessed for response after the first two cycles; response duration,
overall survival, and adverse events were also recorded. We estimated an improvement in historical response rate by 30% would
have clinical meaning.
Results A total of 39 patients were accrued and all were assessed for toxicity; 30 patients were evaluable for response. The median
age was 57.8 years (31–79 years) and 74% were male. Two patients had a complete response, with nine patients achieving a partial
response. The total response rate was 28%, with nine patients not evaluable for response. The median response duration was
noted at 5.97 months and median overall survival was 8.98 months. There were no grade 5 treatment related events, with all
deaths secondary to disease progression. Only five grade 4 events occurred (neutropenia, hyperkalemia, hypokalemia (2), thrombosis/embolism)
without grade 4 diarrhea or sensory neuropathy.
Conclusions Oxaliplatin, irinotecan, and capecitabine given in a novel, weekly schedule does induce responses in advanced gastric and
GEJ adenocarcinoma. However, the total response rate is modest and not an improvement over other regimens. 相似文献

Advanced gastroesophageal cancer patients are often treated with systemic combination chemotherapy. The V-325 study demonstrated that adding docetaxel (D) to a frequently used regimen of cisplatin and 5-fluorouracil (CF) provided benefits with regard to overall survival, response rate, time-to-disease progression, clinical benefit, and health-related quality of life. Although the DCF regimen provides these advantages, it is accompanied by an increase in toxicity compared with the doublet regimen. The toxicity profile of DCF is acceptable only with appropriately selected patients and comprehensive toxicity management strategies. The objective of the current review was to identify trials that investigated modifications to the original DCF regimen to improve its toxicity profile and summarize response rate and toxicities. An attempt was also made to summarize ongoing modifications of the DCF regimen. MEDLINE, major meeting proceedings, and the government clinical trials website were searched until 2007. The modified DCF regimens appear to improve the toxicity profile when compared with the original DCF regimen. The docetaxel-based triplet combinations appear to have a higher response rate than the doublet combinations. Many institutions and cooperative groups continue to study docetaxel-based modifications of the DCF regimen to treat patients with gastroesophageal carcinoma. However, although modified DCF reduces the frequency of severe toxicities previously reported with DCF, considerably more advances are needed to improve the safety, survival, and convenience of patients with advanced gastroesophageal cancer. 相似文献

BACKGROUND: Capecitabine is a rationally designed oral, tumor-activated fluoropyrimidine carbamate with high activity in metastatic breast cancer. This multicenter phase II study was designed to evaluate further the efficacy and safety of capecitabine in patients with metastatic breast cancer previously treated with a taxane-containing regimen. PATIENTS AND METHODS: All patients had to have documented progression after paclitaxel- or docetaxel-containing chemotherapy. Treatment comprised 3-week cycles of oral capecitabine 1250 mg/m(2) twice-daily for 14 days followed by a 7-day rest period. RESULTS: One hundred and thirty-six patients were enrolled. Disease stabilization occurred in 63 patients (46%) and the overall response rate was 15% (95% confidence interval 10% to 23%), providing an overall tumor control rate of 62%. Median time to progression was 3.5 months, median duration of response was 7.5 months and median overall survival was 10.1 months. Capecitabine was generally well-tolerated: most treatment-related adverse events were grade 1/2 in intensity; grade 3/4 treatment-related adverse events were hand-foot syndrome (13%), diarrhea (8%), vomiting (4%) and nausea (3%). There were no treatment-related deaths. CONCLUSIONS: This study confirms that capecitabine achieves a high tumor control rate in heavily pretreated patients with metastatic breast cancer. Due to its favorable safety profile and convenient oral administration, capecitabine can be given as an outpatient therapy. Capecitabine should be considered the reference treatment in this setting based on consistently high efficacy and good tolerability. 相似文献

Purpose. To evaluate the efficacy and the toxicity profile of the sequential administration of doxorubicin and docetaxel as first-line chemotherapy in metastatic breast cancer (MBC).
Patients and methods. Eighty-one patients received a total of 436 cycles of chemotherapy: 236 of doxorubicin (75 mg/m2) and 200 of docetaxel (100 mg/m2 every 21 days). The first 35 patients received doxorubicin every 14 days with G-CSF support, and in the other 46 cases doxorubicin was administered every 21 days without G-CSF.
Results. After entire treatment the overall response rate was 65% (18 complete responses). With a median follow-up of 19 months (range, 1–48 months), the median time to progression was 11.3 months and the median survival time was 31 months. As expected, febrile neutropenia was the most important toxicity and it appeared in 26 cycles (6%) and 19 patients (23%). In the patients that received doxorubicin every 14 days, the febrile neutropenia incidence was higher during docetaxel treatment, especially after its first administration.
Conclusions. The dose and schedule of doxorubicin and docetaxel used in this trial seems to be active in first-line treatment of patients with MBC. The toxicity profile appears to be better than observed with concomitant schedules. 相似文献
