High-dose chemotherapy with autologous stem cell support (HDC-ASCS) can produce high complete remission rates in patients with metastatic breast cancer (MBC). However, the majority of those so treated will relapse within 3 years. The ability of such patients to tolerate further myelosuppressive chemotherapy may be limited and the best therapy is undefined. In this retrospective study we assessed the role of capecitabine as initial therapy after relapse. Ten patients (median age = 47 years; oestrogen receptor-positive, n = 4; visceral disease, n = 6; prior anthracycline, n = 8, prior taxanes, n = 10), whose disease progressed at a median of 246 days (range 69-480) after HDC-ASCS and who were treated with capecitabine (2500 mg/m2 per day for 2 weeks of a 3-week cycle) as initial therapy for relapse, were assessed retrospectively for response and toxicity. They received a median of eight cycles (range 4-24) of capecitabine. The toxicities encountered while receiving capecitabine were: hand-foot syndrome (grade 1, n = 3; grade 2, n = 4; grade 3, n = 1); diarrhoea (grade 1, n = 1; grade 2, n = 3); nausea (n = 2) and fatigue (n = 5). Haematological toxicity was seen in only one patient. No patient required hospitalization for toxicity. Three achieved a complete remission, four a partial remission and three disease stabilization. After a median follow-up of 183 days from commencing capecitabine (range 97-540), all patients were alive and five were in remission. Five progressed after remissions that lasted between 63 and 252 days. Oral capecitabine is an active and well-tolerated agent when used alone as first-line therapy in patients who have relapsed after HDC-ASCS for MBC.

Anthracyclines, together with taxanes, are at present the most active agents in metastatic breast cancer, while single-agent, bolus 5-fluorouracil (5-FU) is not very active in this setting. In view of encouraging results and tolerable toxicity of continuous infusion of 5-FU in gastrointestinal cancer, innovative oral 5-FU agents such as capecitabine have been developed. Capecitabine is a prodrug that is converted into the active compound 5-FU preferentially at the tumor site. An intermittent dosing schedule of capecitabine twice daily at a dose of 2510 mg/m2/day on days 1-14 in a 3-week cycle appeared to be feasible and resulted in a high dose intensity. A large phase II study investigating capecitabine in 135 advanced breast cancer patients, pretreated with anthracyclines and taxanes, observed three complete and 24 partial responses (response rate, 20%), with a mean duration of 8.0 months. Preliminary results of a study comparing capecitabine with paclitaxel in 42 breast cancer patients failing anthracyclines indicate that the efficacy of capecitabine is comparable to that of paclitaxel, with response rates of 36% and 21%, respectively. Another study reported a response rate of 25% for capecitabine as first-line therapy for advanced breast cancer in women aged > or = 55 years, which tended to be better than combination chemotherapy with cyclophosphamide/methotrexate/5-FU. In all studies, capecitabine side effects were mainly mild, and treatment-related grade 3/4 toxicity consisted of diarrhea (8%-11%), nausea (4%-11%), hand-foot syndrome (10%-18%), neutropenia (3%-20%), and bilirubin elevation (6%). Capecitabine is clearly an active agent for the treatment of breast cancer. It is currently registered in various countries for use in third-line treatment of metastatic disease. Its further role will have to be defined from data of randomized phase III studies.

The objective of this study was to investigate the possible prognostic factors in patients with metastatic colorectal cancer (CRC) treated with protracted venous infusion (PVI) of 5-fluorouracil (5-FU). PVI of 5-FU is considered to be one of the standard therapies for patients with CRC because of its high efficacy and low toxicity, but possible prognostic factors in patients with CRC treated with PVI of 5-FU have not been reported until now. One hundred two consecutive patients with metastatic CRC, treated with PVI of 250 mg/m(2) /d of 5-FU at the National Cancer Center Hospital between January 1991 and December 1998, were investigated retrospectively. The data were evaluated for possible correlations with clinicopathologic indices or prognosis. In this study, grade III nausea, stomatitis, diarrhea, and hand-foot syndrome occurred in only 3%, 5%, 5%, and 6% of cases, respectively. No grade III or more hematologic toxicities were observed. The overall response (complete response + partial response) rate for all 102 cases was 26%, with a 95% CI of 18% to 35%. Overall median survival time for the 102 cases was 303 days. In multivariate analysis, the favorable prognostic factors were normal albumin level (<or=3.7 g/dl), histologic grades I, II, and low carcinoembryonic antigen level (<100 ng/ml).

Capecitabine, a tumor-selective, oral fluoropyrimidine, has demonstrated significant antitumor activity in patients with metastatic breast cancer. In this open-label monocenter phase II study the efficacy and safety of capecitabine in patients with metastatic breast cancer who relapsed after high-dose chemotherapy was examined. Female patients 18-65 years of age, with a histologically confirmed diagnosis of metastatic breast cancer, who relapsed after high-dose chemotherapy (adjuvant and/or metastatic) followed by autologous peripheral blood stem cell transplantation (PBSCT) and who had been treated in their course of the disease with an anthracycline and/or an anthracycline/taxane containing regimen were included into this clinical study. Capecitabine was applied as the first salvage chemotherapy at relapse after high-dose chemotherapy (1250 mg/m(2) b.i.d. p.o. for 14 days followed by 7 days rest period). Responding patients or those with stable disease after two treatment cycles were offered to continue treatment until tumor progression. Response rate, time to disease progression, survival, toxicity and quality of life were assessed. Fourteen patients between 35 and 60 years (median 45.5 years) entered this study and received a median number of 5 cycles (range 1-19) of capecitabine. All patients were evaluable for response. All patients had been pretreated with 1-2 cycles of high-dose chemotherapy plus PBSCT. Furthermore, 13 patients had additionally received local radiotherapy. On average, the patients showed metastatic disease in two organ sites (range 1-4 sites). One patient obtained a complete response and five patients a partial response, accounting for a response rate of 42.9% [95% confidence interval (17.7%; 71.1%)]. All responses were already achieved at the first observation time point 6 weeks after treatment initiation. Two further patients obtained stable disease for at least 12 weeks. At the time of final analysis all patients have progressed. Median time to progression was 2.8 months (range 0.4-13.3 months). No median survival time was reached (range 3.9-36.5 months, at the time of reporting eight patients were alive and six patients had died). Two patients developed grade III granulocytopenia. Five patients developed grade III hand-foot syndrome. One patient had the combination of nausea, fever and diarrhea grade III. All adverse events were considered manageable. We conclude that capecitabine as single-agent oral chemotherapy is active and well tolerated in heavily pretreated patients with breast cancer. It can be safely used in patients who have been intensively pretreated by myelotoxic chemotherapy or who have even relapsed after high-dose chemotherapy with PBSCT.

Capecitabine (Xeloda) is an oral prodrug that is enzymatically converted to fluorouracil (5-FU) within cancer cells. Data from two large phase III trials performed in patients receiving first-line chemotherapy for metastatic colorectal cancer showed that capecitabine yielded higher objective response rates and equivalent median time to tumor progression and overall survival rates as 5-FU/leucovorin. In these studies, capecitabine demonstrated lower rates of diarrhea, stomatitis, nausea, and severe neutropenia than bolus 5-FU/leucovorin, but a higher rate of hand-foot syndrome and hyperbilirubinemia. The natural extension of this work has been to evaluate substitution of capecitabine for 5-FU/leucovorin in combination chemotherapy trials with irinotecan (CPT-11, Camptosar) or oxaliplatin (Eloxatin). This is especially important due to concerns regarding toxicities observed with regimens that combine bolus 5-FU/leucovorin with irinotecan or oxaliplatin. Phase I/II and phase II trials of capecitabine in combination with irinotecan or oxaliplatin in patients with advanced disease indicate that the combinations are well tolerated and produce response rates that are in the range of those that would be expected with infusional 5-FU/leucovorin combined with irinotecan or oxaliplatin. Phase III trials have been initiated in the advanced disease and adjuvant settings and should help determine the efficacy, toxicity, and tolerability of the capecitabine/irinotecan or capecitabine/oxaliplatin combination in direct comparison to intravenous 5-FU/leucovorin and irinotecan or oxaliplatin.

The combination of cisplatin and 5-fluorouracil (5-FU) is considered to be the standard treatment in induction chemotherapy for patients with squamous cell carcinoma of the head and neck. Capecitabine (Xeloda) is an oral fluoropyrimidine that is preferentially activated at the tumoral level, exploiting the higher thymidine phosphorylase activity in tumoral tissue. This phase I trial was conducted in patients with locally recurrent or metastatic head and neck carcinoma. The treatment plan included cisplatin on day 1 every 21 days, followed by capecitabine twice daily from day 2 to day 15, with a 1-week rest period. Pharmacokinetic investigations concerned plasma measurement of unchanged capecitabine, 5'-deoxy-5-fluorocytidine, 5'-doxifluridine and 5-FU using an optimized high performance liquid chromatography method, and cisplatin measurement in plasma using a limited sampling procedure. Twenty-one patients were included (mean age 61 years, range 46-76 years). Dose (mg/m(2)) increments for cisplatin and capecitabine (b.i.d.), respectively, were as follows: level 1, 80 and 1000 (three patients); level 2, 100 and 1000 (12 patients); and level 3, 100 and 1125 (five patients). Dose-limiting toxicities occurring during the first cycle (grade >/= 3) were observed on level 2 (one patient with diarrhea, nausea, vomiting, hand-foot syndrome, one toxic death due to renal failure and neutropenia, one patient with neutropenia) and on level 3 (one patient with diarrhea, one patient with hand-foot syndrome and one patient with neutrothrombocytopenia). Due to delayed side-effects, 14 patients (67%) had repeated cycles every 28 days instead of 21 days as initially planned. Objective response was obtained in seven patients (three complete responses and four partial responses). There was no evidence of pharmacokinetic-pharmacodynamic relationships with the drugs and metabolites investigated. Combination of capecitabine and cisplatin is feasible, with a very promising response rate. The recommended doses for further phase II studies are those of level 2 with cisplatin 100 mg/m(2) on day 1 and capecitabine 1000 mg/m(2) b.i.d. on days 1-14, every 28 days.

Oral capecitabine is a highly active, well-tolerated and convenient treatment for breast and colorectal cancer. This trial assessed the efficacy and safety of single-agent capecitabine in patients with previously treated ovarian cancer. A total of 29 patients with platinum-pretreated relapsed ovarian cancer were enrolled in this prospective, open-label, single-centre, phase II study. Patients received oral capecitabine 1250 mg m(-2) twice daily on days 1-14 of a 21-day cycle. Tumour response was evaluated using serum CA125. Out of 29 enrolled patients, 28 were evaluable, and a response was observed in eight patients (29%, 95% confidence interval (CI), 13-49%). Median progression-free and overall survivals were 3.7 (95% CI, 2.8-4.6) and 8.0 (95% CI, 4.1-11.8) months, respectively. After 6 months of treatment, 28% (95% CI, 13-48%) of patients remained progression-free and 62% (95% CI, 42-79%) were still alive. The most common clinical adverse events were hand-foot syndrome (HFS), nausea and diarrhoea. Grade 3 HFS occurred in 14% of patients, grade 3 vomiting in 10%. Efficacy and safety of capecitabine compare favourably with other monotherapies in platinum-refractory epithelial ovarian cancer. The convenience and improved safety profile of capecitabine compared with intravenous. regimens make it an ideal agent for administration in the outpatient setting.

Doxorubicin is considered among the most active single agents used against advanced breast cancer. Recent advances in the design of liposomes as carriers of cytotoxic drugs have resulted in a new formulation of doxorubicin with improved pharmacokinetic and tumor-localizing properties. The objectives of this dose-escalating pilot study were to evaluate the efficacy and safety of the sterically stabilized, pegylated liposomal doxorubicin (Lipo-Dox) for the treatment of metastatic breast cancer. Lipo-Dox was given at the dosage of 45 mg/m2 over 1 hr of intravenous infusion every 4 weeks initially and could be escalated up to a maximum of 60 mg/m2. Response was assessable in 17 of 19 intent-to-treat patients. An objective response was achieved in 41.2% (95% confidence interval: 17.8%-64.6%) of patients (5.9% complete response and 35.3% partial response), and 23.5% had stable disease. Median time to disease progression was 163 days. Major treatment-related toxicities included neutropenia, stomatitis, and skin toxicity in this dose-escalation program. Impressively, no grade 4 toxicities have ever been observed. The only grade 3 nonhematological toxicity ever to occur was reversible skin toxicity, presented as palmar-plantar erythrodysthesia. No severe nausea/vomiting, wig-necessary alopecia, or significant cardiac function change were encountered. In conclusion, Lipo-Dox is shown by this first reported pilot study to be an active agent for treatment of advanced breast cancer with a safety profile that differs markedly from free doxorubicin. The dosage of 45-60 mg/m2 every 4 weeks was well tolerated. Because myelosuppression and other nonhematological toxicities associated with Lipo-Dox were generally mild and acceptable, further assessment of this drug particularly in combination with other chemotherapeutic drugs in the management of early or advanced breast cancer is suggested.

Combination protocols of 5-fluorouracil/leucovorin (5-FU/LV) plus irinotecan or oxaliplatin have demonstrated high activity in metastatic colorectal cancer. Capecitabine, an oral 5-FU prodrug, may replace infusional 5-FU/LV in combination protocols with irinotecan or oxaliplatin. We therefore initiated a phase II study with capecitabine plus either irinotecan or oxaliplatin to determine the efficacy and toxicity of specific combination protocols in patients with advanced gastrointestinal (GI) tumors. Capecitabine 1000 mg/m(2) taken orally twice a day on days 1-14, plus oxaliplatin 70 mg/m(2) on days 1 and 8, or irinotecan 100 mg/m(2) on days 1 and 8; repeated every 3 weeks in an outpatient setting. Patient and tumor characteristics were as follows: median age, 68 years (range, 34-77 years); sex: 10 women, 33 men; tumor types: 35 colorectal cancer; 8 other GI tumors including 5 gastric, 2 pancreatic, and 1 duodenal cancer. All 43 patients treated were evaluable for toxicity (capecitabine/oxaliplatin, 24 patients; capecitabine/irinotecan, 19 patients), and 39 were evaluable for efficacy (capecitabine/oxaliplatin, 22; capecitabine/irinotecan, 17). Grade 3/4 toxicities (National Cancer Institute Common Toxicity Criteria Version 2.0) were limited to diarrhea, 9 patients (capecitabine/irinotecan, n = 5; capecitabine/oxaliplatin, n = 4); hand-foot syndrome, 1 patient (capecitabine/irinotecan); nausea, 2 patients (capecitabine/oxaliplatin); vomiting, 1 patient (capecitabine/oxaliplatin); and peripheral neuropathy, 1 patient (capecitabine/oxaliplatin). No grade 3/4 myelosuppression was noted for either protocol. Capecitabine/irinotecan and capecitabine/oxaliplatin demonstrated significant clinical activity in colorectal cancer and other GI cancers as first-line and salvage therapy. Capecitabine/oxaliplatin and capecitabine/irinotecan show an excellent safety profile and clinical activity in colorectal cancer and other advanced GI tumors. The main toxicity in both arms was manageable diarrhea. This trial served as basis for a randomized multicenter phase II study comparing capecitabine/oxaliplatin and capecitabine/irinotecan as first-line therapy in patients with advanced colorectal cancer.

Capecitabine is a fluoropyrimidine carbamate capable of exploiting the high concentrations of thymidine phosphorylase in tumor tissue to achieve activation preferentially at the tumor site. Thymidine phosphorylase activity is high in renal cell carcinoma tissue. Interferon alfa has been proved to be the agent for standard therapy in metastatic renal cell carcinoma. The purpose of the study was to assess the efficacy and toxicity of combining capecitabine and interferon alfa-2A in patients with advanced renal cell carcinoma. Twenty-five patients with advanced renal cell carcinoma and no prior systemic therapy were treated with the combination of capecitabine at a dose of 1,250 mg/m2 twice daily for 2 weeks after every 21 days and interferon alfa-2A 6 million U three times a week. The overall response rate was 24.0% (95% CI, 9.4-45.1%), from 6 responded patients 5 had partial responses and 1 complete response. Stable disease status was achieved in 9 patients (36.0% with 95% CI 18.0-57.5%). The median survival time was 248 days (95% CI, 173-265 days). The median time to progression was 126 days (95% CI, 49-165 days). Grade 3-4 toxicities occurred in 12 patients and included fatigue (33.3%), nausea, hand-foot syndrome (both 12.5%), anorexia (8.3%), vomiting, anemia and neutropenia (all 4.2%). The capecitabine and interferon alfa-2A combination has clinical activity and an acceptable toxicity profile in patients with metastatic renal cell carcinoma. The importance of adding capecitabine to interferon alfa needs to be confirmed in a randomized trial.
