To evaluate the efficacy and toxicity of capecitabine as a salvage chemotherapy regimen in Chinese patients with recurrent or metastatic nasopharyngeal carcinoma (NPC) previously treated with platinum-based chemotherapy, 17 patients with recurrent or metastatic NPC previously treated with platinum-based chemotherapy as adjuvant or palliative treatments received oral capecitabine at a dose of 1.25 G/m(2) twice daily in 3-week cycles consisting of 2 weeks of treatment followed by rest period of 1 week. Seven patients had local recurrence, seven had distant metastases, one had loco-regional recurrence, and two had both local/regional recurrence and distant metastases. Patients received a median number of three cycles of capecitabine (range: 1-6). The median follow-up was 7.5 months (range: 3-25.3). All patients were included in the efficacy and adverse events analysis. Three patients (17.6%) achieved partial response and one patient (5.9%) achieved complete response, with an overall response rate of 23.5% (95% confidence interval, 7-50%). The duration of response's were 4.2, 5, 6+, and 23.1+ months. Nine patients (52.9%) had stable disease whereas four (23.5%) had progressive disease. The median time to progression was 4.9 months. The median survival was 7.6 months. Five patients are still alive with an estimated 1-year survival rate of 35%. Treatment-related adverse events were generally mild except hand-foot syndrome which occurred in 58.8% of patients. Capecitabine is an effective salvage regimen in patients with recurrent and metastatic NPC. Capecitabine as a single agent or in combination with other chemotherapeutic agents or treatment modalities should be further studied in NPC.

34 patients with advanced unresectable or metastatic urothelial carcinoma who had not received prior chemotherapy for metastatic disease were treated with pegylated-liposomal doxorubicin (PLD) 50 mg/m(2) by a 1-h intravenous infusion (i.v.) every 4 weeks in a multi-institutional phase II trial. 6 of 30 evaluable patients had a partial response to treatment (20%; 95% Confidence Interval (CI), 8-39%) and seven patients had stable disease. Toxicities were primarily non-haematological, but severe palmar-plantar erythrodysesthesia (PPE), lethargy and anorexia were infrequent. Despite a high proportion of patients with poor prognostic features, PLD had clinically significant activity in urothelial cancer in this study. The activity and unique toxicity profile of this drug make it of interest for further study in advanced urothelial cancers in combination with other active agents.

The purpose of this study was (i) to determine the maximum tolerated dose (MTD) of docetaxel that can be administered in combination with Doxil, given without and with granulocyte colony stimulating factor (G-CSF), (ii) to define the pharmacokinetics (PK) of docetaxel when used in combination with Doxil, and (iii) to make preliminary observations on the anti-tumor activity of this combination in patients with metastatic solid tumors. Thirty-seven patients with metastatic cancer were enrolled. Courses were repeated every 3 weeks. Patients received a fixed dose of Doxil 30 mg/m(2) in combination with escalating doses of docetaxel ranging from 40 to 100 mg/m(2). After encountering dose-limiting febrile neutropenia, subsequent escalation was accomplished with G-CSF support. Selected patients at the recommended phase II dose underwent PK evaluation. The most common toxicity observed was neutropenia. Dose-limiting toxicity (30 mg/m(2) Doxil + 80 mg/m(2) docetaxel) was febrile neutropenia in three of six patients treated without G-CSF. Major non-hematological toxicities included alopecia, mucositis and hand-foot syndrome, and were observed after cumulative doses of chemotherapy. Objective responses (complete/partial) were documented in eight of 37 patients (four with breast cancer) and stable disease was seen in 17 patients. PK studies showed an increased tissue retention (decreased clearance) of docetaxel when given with Doxil. The recommended phase II dose of Doxil/docetaxel is 30/60 mg/m(2), q3 weeks, without G-CSF. Further dose escalation to 30/80 mg/m(2) is safe with G-CSF support. Anti-tumor activity, particularly against breast cancer, was observed at various dose levels. Our observations should provide evidence for phase II studies of this combination in patients with breast cancer and other anthracycline/taxane-sensitive cancers.

An open-label, non-randomized, compassionate-use study was carried out to investigate the effects of oral capecitabine at a dose of 1 250 mg/m2 twice daily on days 1 to 14 every 21 days in anthracycline- and taxane-pretreated advanced/metastatic breast cancer patients. Forty-eight patients were enrolled from April 2000 to December 2001. Twenty-four patients (50%) had metastases to the liver, 18 to bone, 13 to lung, 10 to regional lymph nodes, 8 to pleura, 7 to the thoracic wall, 5 to skin, 3 to the mediastinum, 1 to breast and 1 had metastasis to the abdomen. Thirty-three patients (69%) had metastases to more than one site. Median age of the patients was 55 years (range 35-74). Three patients had an ECOG performance status (PS) of 0, 32 PS 1 and 13 PS 2, respectively. Fourteen patients (29%; 95% CI 16 to 42%) obtained a partial response (PR) while 16 (33%) had stable disease (SD) as the best response, of whom 6 had stabilization for more than 24 weeks. This gives a clinical benefit (PR + SD > 24 weeks) of 42% (95% CI 28 to 56). Dose reduction was necessary in 29% of the patients. Median dose reduction was 25%. Grades 2 and 3 hand-foot syndrome (PPE) was observed in 17 patients (36%). Eleven patients experienced grades 2 and 3 gastrointestinal toxicity, and haematological toxicity grade 3 was observed in 3 patients (6%). Median time to progression was 107 days (CI 95% 85 to 129), and median overall survival was 281 days (CI 95% 164 to 398). Third-line, oral capecitabine in anthracycline- and taxane-pretreated metastatic breast cancer appears to be effective and has an acceptable toxicity profile.

A phase I pharmacokinetics and dose-finding study and a phase II study of the combination of pegylated liposomal doxorubicin HCl (PLD) and paclitaxel were conducted in patients with recurrent or metastatic head and neck cancer (HNC). Sixty patients with recurrent or metastatic disease were enrolled in the study: 11 patients in the phase I study and 49 patients in the phase II study. In the phase I study, the initial dose level of PLD was 35 mg/m as a 1-h infusion with escalating increments of 5 mg/m until the maximum tolerated dose (MTD) was reached. A fixed dose of paclitaxel (175 mg/m) was administered as a 3-h infusion. The combination was administered every 28 days. Pharmacokinetic studies performed on 10 patients indicated that the sequence of drug administration did not cause clinically significant modifications in the pharmacokinetics of either drug. The MTD for PLD was 45 mg/m (dose level 3) and the dose-limiting toxicity was febrile neutropenia, occurring in three of five patients. The phase II dose of PLD was 40 mg/m (dose level 2) and a total of 214 cycles were delivered. Grade 3 or 4 neutropenia was observed in 26% patients and febrile neutropenia occurred in 16% of patients. Grade 3 palmar-plantar erythrodysesthesia (PPE) was recorded in only one patient. The overall response rate was 28% for patients with non-nasopharyngeal tumors [95% confidence interval (CI) 15-45%] and 28.6% for the study population (95% CI 17-43%). The median survival for the study population was 9.7 months; 1-year survival was 38%. We conclude that the recommended dose for the combination of PLD and paclitaxel is 40 and 175 mg/m every 28 days, without granulocyte colony stimulating factor support. The combination of paclitaxel with PLD demonstrated activity in recurrent or metastatic HNC, a favorable toxicity profile and relative ease of administration.

Patients with soft tissue sarcoma (STS), even after complete local disease control, often relapse locally or with distant metastases. This multicenter phase II study was conducted to evaluate the safety and efficacy of the combination of pegylated liposomal doxorubicin (PLD) and paclitaxel, as first-line treatment in patients with advanced STS. In all, 42 patients with locally advanced or metastatic STS, median age 54 years and median Eastern Cooperative Oncology Group performance status (PS) 1 were treated with PLD 45 mg m(-2) and paclitaxel 150 mg m(-2), every 28 days for a total of six cycles. Histological types included mainly leiomyosarcomas (43%), malignant fibrous histiocytomas (14%) and liposarcomas (12%). At study entry, 69% of patients had distant metastases. Overall response rate was 16%, including one complete (CR 2%) and six partial responses (PRs 14%), while an additional 14 patients had disease stabilization (SD 33%). At median follow-up 41.5 months, median time to progression (TTP) was 5.7 months with median overall survival (OS) 13.2 months. Grade 3-4 toxicities included neutropenia (17%), anaemia (15%), neurotoxicity (5%) and palmar-plantar erythrodysesthesia (9%). There were no treatment-related deaths. The combination of PLD and paclitaxel is a safe and well-tolerated regimen demonstrating modest efficacy as first-line treatment in patients with advanced STS.

The efficacy of combination therapy with irinotecan and capecitabine has been demonstrated for the first-line treatment of metastatic colorectal cancer (MCRC). The aim of this trial was to evaluate the efficacy and safety of this combination in MCRC as second-line treatment after failure of 24-h infusional 5-fluorouracil (5-FU24h) and folinic acid (FA). Patients pre-treated with 5-FU24h/FA were recruited at two institutions to receive 6 x weekly irinotecan 70 mg/m2 and capecitabine (1000 mg/m2 b.i.d. days 1-14 and 22-35). Courses were repeated on day 50. In elderly patients (>65 years) a 20% dose reduction of both drugs was scheduled. Twenty-eight patients [M/F 20/8; median age 65 years (range 44-79); median ECOG score 1] were enrolled. The most frequent sites of metastases were liver, n=20, lymph nodes and lungs, n=10, respectively. Half of the patients had two or more metastatic sites. A total of 71 treatment courses (median 2, range 1-8) were administered. Main toxicities [worst per patient (%); CTC grade 1/2/3/4] were: anaemias 18/14/-/-; leukocytopenia 11/21/-/-; thrombocytopenia 11/-/-/-; diarrhea 18/36/21/-; nausea/vomiting 43/29/4/-; mucositis 4/11/-/-; alopecia 7/25/-/-; hand-foot syndrome 7/21/-/-; fatigue 14/14/-/-; renal insufficiency (caused by diarrhea and exsiccosis) -/-/-/7. Dose intensity in the first course was [median/mean (%)]: irinotecan 92/83; capecitabine 88/82. Twenty-three patients are evaluable for response analysis (five did not complete the first course): three patients showed partial remissions (13%) and 11 patients had stable disease (48%). Median time to progression was 3.0 months for the total population (range 1.4-17.3) and 6.5 months for responders (partial response plus no change). Seventy-four percent of the patients received a third-line therapy. Overall survival was 15.7 months calculated from the start of study treatment. Second-line therapy with irinotecan and capecitabine yielded a tumor control in 61% of patients with MCRC. Efficacy and toxicity data are comparable to 5-FU/irinotecan combinations, although the likelihood of severe diarrhea appears to be higher with capecitabine/irinotecan.

We retrospectively evaluated acute toxicity in 88 patients that were treated with capecitabine and concurrent radiotherapy to the upper abdomen. These patients included 28 (32%) with pancreatic adenocarcinoma, 18 (20%) with cholangiocarcinoma, 11 (13%) with ampullary carcinoma, 11 (13%) with other primary tumors, 14 (16%) with liver metastases, and 6 (7%) with metastases at other sites. The median dose of radiotherapy was 45 Gy (range 30-72 Gy). The median dose of capecitabine was 850 mg/m(2) twice daily, with 77% receiving 800-900 mg/m(2) twice daily. The highest grade of acute toxicity was Common Terminology Criteria (CTC) grade 0 in 5 (6%), grade 1 in 60 (68%), grade 2 in 18 (20%), and grade 3 in 5 (6%) patients. No patient had CTC grade 4 toxicity. The most common grade 2 toxicities were nausea, hand-foot syndrome, fatigue, anorexia and diarrhea. The grade 3 toxicities included nausea, vomiting and fatigue. Three patients (3%) required hospitalization due to grade 3 acute toxicity. Capecitabine was interrupted, discontinued or given at an adjusted dose in 13 (15%) patients because of acute toxicity. Therefore, capecitabine and concurrent radiotherapy to the upper abdomen appears to be well tolerated. Capecitabine may serve as an alternative to bolus or infusional 5-FU during chemoradiation for upper gastrointestinal malignancies.

Renal cell cancer (RCC) is a relatively uncommon malignancy, with 51,190 cases expected to be diagnosed in 2007. Localized disease is curable by surgery; however, locally advanced or metastatic disease is not curable in most cases and, until recently, had a limited response to drug treatment. Historically, biologic response modifiers or immunomodulating agents were tested in clinical trials based on observations that some cases of RCC can spontaneously regress. High-dose aldesleukin is approved by the United States Food and Drug Administration as a treatment for advanced RCC; however, the drug is associated with a high frequency of severe adverse effects. Responses have been observed with low-dose aldesleukin and interferon alfa, but with little effect on overall survival. Sorafenib and sunitinib are novel therapies that target growth factor receptors known to be activated by the hypoxia-inducible factor and the Ras-Raf/MEK/ERK pathways. These pathways are important in the pathophysiology of RCC. Sorafenib and sunitinib have shown antitumor activity as first- and second-line therapy in patients with cytokine-refractory metastatic RCC who have clear-cell histology. Although complete responses are not common, both drugs promote disease stabilization and increase progression-free survival. This information suggests that disease stabilization may be an important determinant for response in RCC and possibly other cancers. Sorafenib and sunitinib are generally well tolerated and are considered first- and second-line treatment options for patients with advanced clear cell RCC. In addition, sorafenib and sunitinib have shown promising results in initial clinical trials evaluating antitumor activity in patients who are refractory to other antiangiogenic therapy. The most common toxicities with both sorafenib and sunitinib are hand-foot syndrome, rash, fatigue, hypertension, and diarrhea. Research is directed toward defining the optimal use of these new agents.

S-1 is an oral fluoropyrimidine consisting of the 5-fluorouracil prodrug tegafur combined with two modulating substances, gimeracil and potassium oxonate. On the basis of the potential additive effect between mitomycin C (MMC) and 5-fluorouracil as a continuous infusion, we conducted a phase II study to assess the efficacy and tolerability of the combination of S-1 and MMC as second-line chemotherapy for advanced gastric cancer (AGC). Patients with measurable AGC, progressive after one prior chemotherapy for metastatic disease, received MMC (7 mg/m2) on day 1 and S-1 (40 mg/m2) twice daily as an intermittent regimen of 4 weeks of treatment followed by a 2-week rest. Treatment was repeated every 6 weeks. The primary objective was the response rate. For 43 patients registered, 42 patients were treated with MMC plus S-1. A total of 121 chemotherapy cycles were delivered (median: 2; range: 1-6). The patients' median age was 53 years (range: 31-75) and nine (21%) had an Eastern Cooperative Oncology Group performance status of 2. In an intent-to-treat analysis, nine patients (21%) achieved an objective response, which was maintained for 4.1 months. The median progression-free and overall survivals were 3.4 months (95% confidence interval: 2.3-4.5) and 8.0 months (95% confidence interval: 6.1-9.9), respectively. Although fatigue was the most frequently encountered toxicity safety profiles were generally predictable and manageable. One patient developed hemolytic anemia, which was resolved spontaneously. Grade > or = 2 hand-foot syndrome was observed in only three patients. Second-line chemotherapy with MMC and S-1 is an active and tolerable regimen for AGC patients with good performance status.
