Abstract
Functional assay platforms could identify the biophysical properties of cells and their therapeutic response to drug treatments. Despite their strong ability to assess cellular pathways, functional assays require large tissue samples, long-term cell culture, and bulk measurements. Even though such a drawback is still valid, these limitations did not hinder the interest in these platforms for their capacity to reveal drug susceptibility. Some of the limitations could be overcome with single-cell functional assays by identifying subpopulations using small sample volumes. Along this direction, in this article, we developed a high-throughput plasmonic functional assay platform to identify the growth profile of cells and their therapeutic profile under therapies using mass and growth rate statistics of individual cells. Our technology could determine populations' growth profiles using the growth rate data of multiple single cells of the same population. Evaluating spectral variations based on the plasmonic diffraction field intensity images in real time, we could simultaneously monitor the mass change for the cells within the field of view of a camera with the capacity of > ∼500 cells/h scanning rate. Our technology could determine the therapeutic profile of cells under cancer drugs within few hours, while the classical techniques require days to show reduction in viability due to antitumor effects. The platform could reveal the heterogeneity within the therapeutic profile of populations and determine subpopulations showing resistance to drug therapies. As a proof-of-principle demonstration, we studied the growth profile of MCF-7 cells and their therapeutic behavior to standard-of-care drugs that have antitumor effects as shown in the literature, including difluoromethylornithine (DFMO), 5-fluorouracil (5-FU), paclitaxel (PTX), and doxorubicin (Dox). We successfully demonstrated the resistant behavior of an MCF-7 variant that could survive in the presence of DFMO. More importantly, we could precisely identify synergic and antagonistic effects of drug combinations based on the order of use in cancer therapy. Rapidly assessing the therapeutic profile of cancer cells, our plasmonic functional assay platform could be used to reveal personalized drug therapies for cancer patients.

Zhang P, Tu S. MGAE-DC: Predicting the synergistic effects of drug combinations through multi-channel graph autoencoders. PLoS Comput Biol 2023; 19:e1010951. [PMID: 36867661 PMCID: PMC10027223 DOI: 10.1371/journal.pcbi.1010951] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 03/20/2023] [Accepted: 02/14/2023] [Indexed: 03/04/2023] Open
Abstract
Accurate prediction of synergistic effects of drug combinations can reduce the experimental costs for drug development and facilitate the discovery of novel efficacious combination therapies for clinical studies. The drug combinations with high synergy scores are regarded as synergistic ones, while those with moderate or low synergy scores are additive or antagonistic ones. The existing methods usually exploit the synergy data from the aspect of synergistic drug combinations, paying little attention to the additive or antagonistic ones. Also, they usually do not leverage the common patterns of drug combinations across different cell lines. In this paper, we propose a multi-channel graph autoencoder (MGAE)-based method for predicting the synergistic effects of drug combinations (DC), and shortly denote it as MGAE-DC. A MGAE model is built to learn the drug embeddings by considering not only synergistic combinations but also additive and antagonistic ones as three input channels. The later two channels guide the model to explicitly characterize the features of non-synergistic combinations through an encoder-decoder learning process, and thus the drug embeddings become more discriminative between synergistic and non-synergistic combinations. In addition, an attention mechanism is incorporated to fuse each cell-line's drug embeddings across various cell lines, and a common drug embedding is extracted to capture the invariant patterns by developing a set of cell-line shared decoders. The generalization performance of our model is further improved with the invariant patterns. With the cell-line specific and common drug embeddings, our method is extended to predict the synergy scores of drug combinations by a neural network module. Experiments on four benchmark datasets demonstrate that MGAE-DC consistently outperforms the state-of-the-art methods. In-depth literature survey is conducted to find that many drug combinations predicted by MGAE-DC are supported by previous experimental studies.

Co-Delivery of 5-Fluorouracil and Paclitaxel in Mitochondria-Targeted KLA-Modified Liposomes to Improve Triple-Negative Breast Cancer Treatment. Pharmaceuticals (Basel) 2022; 15:ph15070881. [PMID: 35890181 PMCID: PMC9318860 DOI: 10.3390/ph15070881] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 07/14/2022] [Accepted: 07/15/2022] [Indexed: 11/19/2022] Open
Abstract
In this research, KLA-modified liposomes co-loaded with 5-fluorouracil and paclitaxel (KLA-5-FU/PTX Lps) were developed, and their antitumor activity against triple-negative breast cancer (TNBC) was evaluated. KLA-5-FU/PTX Lps were prepared using the thin-film dispersion method, and their in vitro anticancer efficacy was assessed in human breast cancer cells (MDA-MB-231). An MDA-MB-231 tumor-bearing mouse model was also established to evaluate their antitumor efficacy in vivo. KLA-5-FU/PTX Lps showed enhanced cytotoxicity against MDA-MB-231 cells, improved drug delivery to mitochondria, and induced mitochondria-mediated apoptosis. The modified liposomes also showed favorable antitumor activity in vivo due to their strong ability to target tumors and mitochondria. The liposomes showed no obvious systemic toxicity. Our results suggest that KLA-5-FU/PTX Lps are a promising system with which to target the delivery of antitumor drugs to mitochondria as a treatment for TNBC.

Nonplatinum-based therapy with Paclitaxel and Capecitabine for advanced squamous cell carcinomas of the anal canal: A population-based Danish anal cancer group study. Cancer Med 2021; 10:3224-3230. [PMID: 33960701 PMCID: PMC8124117 DOI: 10.1002/cam4.3886] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 03/09/2021] [Accepted: 03/15/2021] [Indexed: 01/04/2023] Open
Abstract
Background First‐line platinum‐based therapy for advanced squamous cell carcinomas of the anal canal (SCCA) implies a risk of substantial side effects, and data on second‐line treatment options are limited. Paclitaxel and Capecitabine are a well‐known regimen with a moderate toxicity profile, but its efficacy has not been evaluated. Methods We conducted a retrospective study using Danish Hospital Registers of patients treated with Paclitaxel and Capecitabine for inoperable, recurrent, or advanced metastatic SCCA in Denmark, between January 2000 and July 2018. Results A total of 52 patients met the eligibility criteria. Median age was 60.7 years (range 42–83). Efficacy was observed, with an overall response rate in patients receiving first‐line (N = 28) and second‐line (N = 23) Paclitaxel and Capecitabine of 39.3% (2 with complete responses) and 17.4%, respectively. Median progression‐free survival (PFS) was 4.5 months (95% CI 3.3–5.9) and 3.8 months (95% CI 2.4–5.5) with OS of 6.7 months (95% CI 5.9–8.5) and 5.9 months (95% CI 3.9–14), respectively. Performance status ≥2 and neutrophil to lymphocyte ratio ≥4 were significantly associated with a short PFS. Conclusion This study recognizes Paclitaxel and Capecitabine as a potential regimen for advanced SCCA, when recommended first‐line therapy is not feasible or as a potential second‐line treatment after failure of platinum‐based chemotherapy.

Gastric Cancer 2020; 23:677-688. [PMID: 32036492 DOI: 10.1007/s10120-020-01043-x] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2019] [Accepted: 01/21/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Oral fluoropyrimidine plus cisplatin is often not tolerated by patients with severe peritoneal metastases of gastric cancer. Combination of 5-fluorouracil (5-FU), l-leucovorin (l-LV), and paclitaxel (FLTAX) has promising activity for such patients. We conducted a phase II/III study comparing FLTAX with 5-FU/l-LV. METHODS Eligibility criteria included: unresectable or recurrent gastric adenocarcinoma; 20-75 years; performance status (PS) 0-2; peritoneal metastases + ; massive ascites and/or inadequate oral intake; no prior chemotherapy. Patients were randomly assigned to receive 5-FU/l-LV or FLTAX. The primary endpoint of phase III was overall survival: UMIN000010949. RESULTS We enrolled 101 patients. Early deaths occurred in patients with PS 2 having massive ascites and inadequate oral intake simultaneously; the protocol was amended to exclude such patients. Median survival times were 6.1 and 7.3 months for the 5-FU/l-LV and the FLTAX arms, respectively (HR 0.792; 80% CI 0.596-1.053; one-sided p = 0.1445). FLTAX arm had longer progression-free survival (PFS) [1.9 vs 5.4 months (HR 0.64; 95% CI, 0.43-0.96; p = 0.029)]. Grade 3/4 adverse events such as leucopenia and anorexia were more frequently observed in the 5-FU/l-LV arm. In the 5-FU/l-LV arm, two deaths were treatment-related. In the 5-FU/l-LV and FLTAX arms, 12 and 3 deaths occurred within 30 days after the last protocol treatment, respectively. CONCLUSIONS Chemotherapy was indicated for patients with severe peritoneal metastases excluding patients with PS 2 having massive ascites and inadequate oral intake simultaneously. FLTAX did not confer a significant survival benefit but may be preferred because of longer PFS and acceptable toxicity.

Abstract
Background: As docetaxel plus S-1 may be feasible for cancer treatment, we conducted a phase I/II trial to determine the recommended docetaxel dose and the fixed S-1 dose (phase I), as well as confirm the regimen’s efficacy and safety (phase II) for previously-treated patients with advanced non-small cell lung cancer. Methods: Patients ≤75 years with performance status ≤1 and adequate organ function were treated at three-week intervals with docetaxel on day 1 and 80 mg/m2 oral S-1 from days 1–14. The starting docetaxel dose was 45 mg/m2 and this was escalated to a maximum of 70 mg/m2. In phase II, response rate, progression-free survival (PFS), overall survival (OS), and safety were assessed. Results: The recommended doses were 50 mg/m2 docetaxel (day 1) and 80 mg/m2 S-1 (days 1–14). Grades 3 and 4 leukocytopenia and neutropenia occurred in 44% and 67% of patients, respectively. Nonhematologic toxicities were generally mild. Overall response to chemotherapy was 7.7% (95% confidence interval (CI), 1.6–20.9%), and median PFS and OS were 18.0 weeks (95% CI; 11.3–22.9 weeks) and 53.0 weeks, respectively. Conclusion: Fifty mg/m2 docetaxel plus 80 mg/m2 oral S-1 had a lower response rate than anticipated; however, the survival data were encouraging. A further investigation is warranted to select the optimal patient population.

Abstract
Motivation While drug combination therapies are a well-established concept in cancer treatment, identifying novel synergistic combinations is challenging due to the size of combinatorial space. However, computational approaches have emerged as a time- and cost-efficient way to prioritize combinations to test, based on recently available large-scale combination screening data. Recently, Deep Learning has had an impact in many research areas by achieving new state-of-the-art model performance. However, Deep Learning has not yet been applied to drug synergy prediction, which is the approach we present here, termed DeepSynergy. DeepSynergy uses chemical and genomic information as input information, a normalization strategy to account for input data heterogeneity, and conical layers to model drug synergies. Results DeepSynergy was compared to other machine learning methods such as Gradient Boosting Machines, Random Forests, Support Vector Machines and Elastic Nets on the largest publicly available synergy dataset with respect to mean squared error. DeepSynergy significantly outperformed the other methods with an improvement of 7.2% over the second best method at the prediction of novel drug combinations within the space of explored drugs and cell lines. At this task, the mean Pearson correlation coefficient between the measured and the predicted values of DeepSynergy was 0.73. Applying DeepSynergy for classification of these novel drug combinations resulted in a high predictive performance of an AUC of 0.90. Furthermore, we found that all compared methods exhibit low predictive performance when extrapolating to unexplored drugs or cell lines, which we suggest is due to limitations in the size and diversity of the dataset. We envision that DeepSynergy could be a valuable tool for selecting novel synergistic drug combinations.

Abstract
BACKGROUND We compared efficacy and safety of paclitaxel/capecitabine therapy followed by capecitabine for maintenance (PACX) versus cisplatin/capecitabine therapy (XP) in advanced gastric cancer. METHODS Multicenter, randomized, phase III trial was conducted in China (December 2009-February 2014). Adults (n = 320) with histologically confirmed, untreated metastatic/unresectable gastric or gastroesophageal junction adenocarcinoma; with ≥ 1 measureable lesions according to Response Evaluation Criteria in Solid Tumors 1.0 criteria; Karnofsky performance score ≥ 70 and life expectancy ≥ 3 months were randomized (1:1) to PACX or XP. PACX group received paclitaxel 80 mg/m2 intravenous on days 1 and 8; capecitabine 1000 mg/m2 orally BD on days 1-14, followed by a 7-day rest interval for 4 cycles, followed by maintenance capecitabine at same dosage/schedule until disease progression, unendurable adverse events or death. XP group received cisplatin intravenous 80 mg/m2 on day 1 and capecitabine at same dosage/schedule as PACX group per cycle for 6 cycles. RESULTS Median progression-free survival (5.0 versus 5.3 months; hazard ratio [95% CI]: 0.906; 0.706-1.164; p = 0.44) and overall survival (12.5 versus 11.8 months; hazard ratio: 0.878 [0.685-1.125]; p = 0.30) were not significantly different between PACX and XP groups. Objective response rate was significantly higher (43.1 versus 28.8%; p = 0.012) and disease control rate was similar (77.5 versus 72.5%; p = 0.75) in PACX versus XP, respectively. Quality of life was significantly improved in PACX versus XP after three treatment cycles. Many treatment-related adverse events were significantly lesser in PACX than XP. CONCLUSIONS First-line chemotherapy with PACX is effective with milder toxicities in advanced gastric cancer, but could not replace XP.

Abstract
OBJECTIVE We assessed the impact of treatment preferences in second-line chemotherapy on breast cancer prognosis using the SELECT BC study. METHODS The SELECT BC study was performed in patients with HER2-negative metastatic breast cancer treated with initial chemotherapy. From these patients, 618 were assigned to 2 groups (S-1 group, 309; taxane group, 309). The S-1 and taxane groups were each subdivided into 3 groups: crossover group, protocol-recommended group, and other group, and the analysis of overall survival (OS) was performed using Cox regression with inverse probability weighting, to adjust for postrandomization confounding. RESULTS In the taxane group, the OS of the crossover group (39.6 months) was better than that of the protocol-recommended group (35.7 months) and the other chemotherapy group (36.9 months) (vs. the protocol-recommended group, HR 0.72 [95% CI 0.52-0.98], p = 0.037; vs. the other chemotherapy group, HR 0.71 [95% CI 0.43-1.18], p = 0.183). In the S-1 group, there was no statistically significant difference in OS between the 3 groups. CONCLUSION The study of the combination of first-line chemotherapy and second-line chemotherapy showed that S-1 might be recommended as a second-line chemotherapy in patients in whom taxane was the primary chemotherapy.

Abstract
Large porous particles (LPPs) could be used as a useful carrier for non-invasive delivery to the deep lung. Pulmonary delivery of paclitaxel-loaded LPPs (PTX-LPPs) can help to eliminate the highly complicated and harmful solvent used in PTX parenteral formulations. PTX-LPPs with mass median aerodynamic diameter (MMAD) of 5.74 ± 0.09 μm, high encapsulation efficiency and good aerosolisation properties were produced using ammonium bicarbonate as porogen. Cytotoxicity of PTX-LPPs on A549 and Calu-6 cell lines was comparable with Free-PTX. Endotracheal administration of PTX-LPPs in rats exhibited PTX plasma concentration in the therapeutic range which lasted 4-fold longer than i.v. injection. The bioavailability was measured as 51 ± 7.1%. The lung targeting efficiency (Te) of PTX-LPPs was 11.9-fold higher than i.v. administration. PTX-LPPs could deliver a higher PTX to lung with a non-toxic plasma level in a longer duration which shows their pulmonary delivery suitability.

Abstract
The standard treatment for patients with advanced gastric cancer (AGC) is still a matter of debate. The chemotherapy regimen of paclitaxel (PTX) combined with S-1 has been used to treat AGC or metastatic gastric cancer.We conducted a meta-analysis to compare oral S-1 and infusional 5-fluorouracil (5-FU) to determine which agent was more efficacious and less toxic in combination with PTX. A systematic review with a meta-analysis was performed. PubMed, EmBase, the Cochrane Central Register of Controlled Trials, and the China National Knowledge Infrastructure databases were searched to select randomized controlled trials (RCTs) comparing PTX plus S-1 and PTX plus 5-FU in patients with AGC.Three RCTs were eligible and 352 patients were analyzed. PTX plus S-1 increased the disease control rate (risk ratio [RR] = 1.14, 95% confidence interval [CI] = 1.00-1.30, P = 0.04) and reduced the progressive disease rate (RR = 0.62, 95% CI] = 0.39-0.98, P = 0.04) compared with PTX plus 5-FU. There was a significant decrease in nausea (RR = 0.60, 95% CI = 0.43-0.82, P = 0.001) and vomiting (RR = 0.55, 95% CI = 0.33-0.91, P = 0.02) in patients treated with PTX plus S-1.PTX plus S-1 was associated with almost equivalent safety and a lower progressive disease rate compared with PTX plus 5-FU. PTX plus S-1 is a good alternative strategy for patients who cannot tolerate a continuous intravenous infusion.

Abstract
PURPOSE This study aimed to compare the efficacy and toxicity of weekly paclitaxel plus S-1 with weekly paclitaxel plus 5-fluorouracil in treating advanced gastric cancer as first line regimen. The primary end-point was disease control rate (DCR). METHODS Patients with advanced or recurrent gastric cancer were randomly assigned to an experimental arm or a control arm. The experimental arm's dosage schedule was paclitaxel 60 mg/m2 (intravenous infusion) on days 1, 8 and 15 and S-1 80-120 mg/d (oral administration) on days 1-14. Control arm patients were given the same paclitaxel, combined with 5-fluorouracil 500 mg/m2 (continuous intravenous infusion) on days 1-5; and leucovorin 20 mg/m2 (intravenous infusion) on days 1-5. All schedules were repeated every 28 d. RESULTS A total of 240 patients were enrolled and equally randomised into two arms. The overall response rate and DCR of the experimental arm was non-inferior to that of the control arm both in the per-protocol set and the full analysis set. The secondary end-point median progression-free survival (PFS) of the experimental and control arms was 153 and 129 d, with the hazard ratio of 0.641 (95% CI: 0.473-0.868, P = 0.004). The hazard ratio of the time to treatment failure of the two arms was 1.449 (95% CI: 0.705-2.980, P = 0.229). The six-month PFS rates of both arms were similar (31.3% versus 31.8%, P = 0.94). Cox regression analysis indicated that only treatment regimen and age were independent predictive factors for PFS. The most common adverse events were haematological and gastrointestinal. The rates of grade 3-4 adverse events were not significantly different between the two study arms and were mostly lower than 5%. CONCLUSION Weekly paclitaxel combined with S-1 is an active and well-tolerated regimen, supporting the view that S-1 can be an alternative for infusional 5-fluorouracil for advanced gastric cancer.

Abstract
AIM The combination of a taxane and capecitabine offers synergistic antitumor activity. This study aimed to determine the efficacy and tolerability of a paclitaxel and capecitabine combination in Thai patients with metastatic breast cancer (MBC) not previously treated for metastatic disease. METHODS This open-label, single-center, non-comparative phase II study was conducted between December 2006 and March 2009. In all 40 MBC patients were treated with oral capecitabine 1000 mg/m(2) twice daily on days 1 to 14, and weekly paclitaxel 80 mg/m(2) in a 3-week cycle for a total of six cycles. RESULTS After a median follow up of 13.4 months, an overall objective response rate of 80%, with a partial response of 74% and a complete response of 5% were achieved. While 8% of patients achieved stable disease, 13% had progressive disease. Median time to progress was 8 months and median overall survival was 24.4 months. One patient discontinued because of hypersensitivity to paclitaxel. There was no grade 4 toxicity. Skin and nail toxicity was found in 75% of patients (with 25% in grade 2 or 3), followed by neutropenia (45% in all with 15% in grades 2 or 3), neuropathy (25% in total with 5% in grade 2) and stomatitis and diarrhea (in both of which 5% experienced grade 1 severity). CONCLUSION A first-line regimen of weekly paclitaxel plus capecitabine is effective and tolerable in Thai MBC patients.

Abstract
BACKGROUND Botanical medicines are increasingly combined with chemotherapeutics as anticancer drug cocktails. This study aimed to assess the chemotherapeutic potential of an extract of Taxus cuspidata (TC) needles and twigs produced by artificial cuttage and its co-effects as a cocktail with 5-fluorouracil (5-FU). METHODS Components of TC extract were identified by HPLC fingerprinting. Cytotoxicity analysis was performed by MTT assay or ATP assay. Apoptosis studies were analyzed by H & E, PI, TUNEL staining, as well as Annexin V/PI assay. Cell cycle analysis was performed by flow cytometry. 5-FU concentrations in rat plasma were determined by HPLC and the pharmacokinetic parameters were estimated using 3p87 software. Synergistic efficacy was subjected to median effect analysis with the mutually nonexclusive model using Calcusyn1 software. The significance of differences between values was estimated by using a one-way ANOVA. RESULTS TC extract reached inhibition rates of 70-90% in different human cancer cell lines (HL-60, BGC-823, KB, Bel-7402, and HeLa) but only 5-7% in normal mouse T/B lymphocytes, demonstrating the broad-spectrum anticancer activity and low toxicity to normal cells of TC extract in vitro. TC extract inhibited cancer cell growth by inducing apoptosis and G(2)/M cell cycle arrest. Most interestingly, TC extract and 5-FU, combined as a cocktail, synergistically inhibited the growth of cancer cells in vitro, with Combination Index values (CI) ranging from 0.90 to 0.26 at different effect levels from IC50 to IC90 in MCF-7 cells, CI ranging from 0.93 to 0.13 for IC40 to IC90 in PC-3M-1E8 cells, and CI < 1 in A549 cells. In addition, the cocktail had lower cytotoxicity in normal human cell (HEL) than 5-FU used alone. Furthermore, TC extract did not affect the pharmacokinetics of 5-FU in rats. CONCLUSIONS The combinational use of the TC extract with 5-FU displays strong cytotoxic synergy in cancer cells and low cytotoxicity in normal cells. These findings suggest that this cocktail may have a potential role in cancer treatment.

Abstract
OBJECTIVE We evaluated the efficacy and safety of bolus 5-fluorouracil (5-FU) and leucovorin combined with weekly paclitaxel (FLTAX) in advanced gastric cancer (GC) patients. METHODS Patients with untreated stage IV GC received paclitaxel 80 mg/m(2) as a 1-hour infusion, followed by 5-FU 600 mg/m(2) as a bolus infusion and L-leucovorin 250 mg/m(2) as a 2-hour infusion on days 1, 8 and 15. Treatment cycles were repeated every 28 days. The primary endpoint was response rate. RESULTS Thirty-five patients were enrolled. The median age was 62 years (range 34-75). Twenty-one patients (60%) had diffuse-type cancer and 11 had peritoneal metastasis. The confirmed response rate was 43% (95% CI 26-61) with 15 partial responses. Stable disease was observed in 16 (46%) patients. Median progression-free survival and overall survival were 6.8 months (95% CI 5.8-7.4) and 16.2 months (95% CI 10.0-22.8), respectively. Grade 3-4 adverse events were: neutropenia (54%), febrile neutropenia (3%), diarrhea (6%) and sensory neuropathy (11%). CONCLUSION FLTAX showed a desirable safety profile, and the efficacy against advanced GC was encouraging. FLTAX may be a good option for GC patients with deteriorated general condition, and a randomized clinical trial in such patients is currently underway.

Abstract
BACKGROUND A multicenter phase II study was conducted to evaluate the efficacy and safety of a combination regimen of weekly paclitaxel plus S-1 in patients with advanced gastric cancer. METHODS Patients with previously untreated metastatic or recurrent gastric cancer received intravenous paclitaxel 50 mg/m(2) on days 1, 8, and 15, plus oral S-1 40 mg/m(2) b.i.d. on days 1 to 14 followed by 2 weeks off, in a 28-day cycle. RESULTS A total of 54 patients were registered. All of them had measurable disease and were determined to be eligible for the present study. Two complete responses and 23 partial responses were confirmed, giving an overall response rate of 46.3%. At a final follow up of 3 years, the median progression-free survival and median overall survival were 6.0 and 14.3 months, respectively. Grade 3 neutropenia occurred in 14 patients, and grade 4 in 1 patient (total, 27.8%). The most serious nonhematological toxicity was diarrhea, where grade 3 occurred in 5 patients (9.3%). There were no treatment-related deaths. CONCLUSION A combination of weekly paclitaxel plus S-1 was found to be well tolerated and effective in patients with advanced gastric cancer. Further investigation with comparative trials is needed for confirmation.

Abstract
PURPOSE There is no effective salvage regimen for failed gemcitabine-based chemotherapy. This study evaluated the efficacy and toxicity of 5-fluorouracil and paclitaxel in patients with gemcitabine-refractory pancreatic cancer. METHODS Between January 2004 and December 2007, 28 patients with pancreatic cancer previously treated with gemcitabine-based chemotherapy were enrolled. 5-Fluorouracil 1,000 mg/m(2) was infused (days 1, 2, and 3) and paclitaxel 175 mg/m(2) (day 1) was administered every 4 weeks. The primary endpoint of this study was efficacy and toxicity and the secondary endpoint was time to progression and overall survival. RESULTS A total of 75 cycles were given, for a mean of 2.68 cycles per patient. The response could be evaluated in 20 patients. Two patients (10%) obtained a partial response, and four patients (20%) had stable disease. The median time to progression and overall survival was 2.5 and 7.6 months, respectively. Grade 3/4 hematological toxicity included neutropenia in six patients (21.4%), anemia in one (3.6%), and thrombocytopenia in one (3.6%). One (3.6%) patient experienced grade 4 neuropathy, and two (7.2%) patients experienced grade 3 diarrhea. CONCLUSION The 5-fluorouracil and paclitaxel combination treatment seems to be effective in patients with advanced pancreatic cancer that did not respond to a gemcitabine-based regimen.

Abstract
OBJECTIVE To determine the dose-limiting toxicity (DLT) and the maximum-tolerated dose (MTD) of combination chemotherapy with leucovorin-modulated weekly bolus 5-fluorouracil (5-FU) and weekly paclitaxel in patients with advanced gastric cancer (GC). METHODS Chemotherapy-naive patients with histologically proven metastatic or recurrent GC were enrolled. Paclitaxel was administered as a 1-h intravenous (i.v.) infusion followed by 5-FU as a bolus i.v. infusion on Days 1, 8 and 15. A 2-h i.v. infusion of l-leucovorin was started at the same time as the paclitaxel infusion on Days 1, 8 and 15. Treatment cycles were repeated every 28 days until disease progression or unacceptable toxicity occurred. Patients were scheduled to receive 5-FU, l-leucovorin and paclitaxel at four dose levels (mg/m(2)/week): 500/250/60 (level 1), 500/250/80 (level 2), 600/250/80 (level 3) and 600/250/100 (level 4), respectively. RESULTS Eighteen patients were enrolled. During the first cycle of the highest dose level (level 4), two of the six patients had DLT involving Grade 3 diarrhea and Grade 3 skin rash. Furthermore, three of the four patients who received the second consecutive cycle of treatment at dose level 4 had Grade 4 neutropenia. Dose level 3 was thus determined to be the MTD. Eleven (61%) of the 18 patients had partial responses, and the median progression-free survival time was 6.8 months. CONCLUSIONS The MTD and the recommended dose for phase II studies of this regimen were determined to be 5-FU 600 mg/m(2)/week, l-leucovorin 250 mg/m(2)/week and paclitaxel 80 mg/m(2)/week.

Abstract
PURPOSE We aimed to examine the safety and antitumor effects of a combination of S-1 and paclitaxel in patients with unresectable or recurrent gastric cancer in a phase I/II setting. PATIENTS AND METHODS The study was designed as a phase I/II clinical trial. In phase I portion, the dose of paclitaxel was escalated to estimate the maximum-tolerated dose (MTD) and recommended dose (RD) of paclitaxel with fixed dose of S-1. S-1 (daily dose, 80 mg/m(2)) was given orally on days 1-21 every 35-day cycle (rest on days 22-35). Paclitaxel was administered intravenously on days 1, 8 and 15, at an initial dose of 40 mg/m(2), stepping up to 70 mg/m(2) in 10-mg/m(2) increment. Dose-limiting toxicity (DLT) was defined as grade 4 hematological toxicity, grade 3 or higher nonhematological toxicity, and treatment discontinuation due to adverse reactions during the first course of treatment. In phase II portion, the efficacy and toxicity at the RD of paclitaxel with S-1 were assessed. RESULTS The MTD of paclitaxel was estimated to be 60 mg/m(2), because >33.3% of patients (2/3) developed DLTs. DLT included postponement of treatment due to grade 2 neutropenia, and grade 3 stomatitis, anorexia, and nausea. Therefore, the RD of paclitaxel was estimated to be 50 mg/m(2). In the phase II portion, 22 patients were evaluated with 50 mg/m(2) paclitaxel and 80 mg/m(2) S-1 in a 35-day cycle. The response rate was 54.5% (95% CI, 32.2-75.6%). The median survival time was 283 days (95% CI, 218-508 days). The median number of treatment courses was 4 (range 1-10), indicating that this regimen could be given repeatedly. CONCLUSIONS This phase I/II trial of combination therapy with S-1 and paclitaxel in patients with unresectable or recurrent gastric cancer showed that this regimen has substantial antitumor activity and can be given safely.

Abstract
Paclitaxel and capecitabine, which have distinct mechanisms of action and toxicity profiles, have each shown high activity as single agents in gastric cancer. Synergistic interaction between these two drugs was suggested by taxane-induced upregulation of thymidine phosphorylase. We, therefore, evaluated the antitumour activity and toxicities of paclitaxel and capecitabine as first-line therapy in patients with advanced gastric cancer (AGC). Patients with histologically confirmed unresectable or metastatic AGC were treated with capecitabine 825 mg m−2 p.o. twice daily on days 1–14 and paclitaxel 175 mg m−2 i.v. on day 1 every 3 weeks until disease progression or unacceptable toxicities. Between June 2002 and May 2004, 45 patients, of median age 57 years (range=38–73 years), were treated with the combination of capecitabine and paclitaxel. After a median 6 cycles (range=1–9 cycles) of chemotherapy, 43 were evaluable for toxicity and response. A total of 2 patients showed complete response and 20 showed partial response making the overall response rate 48.9% (95% CI=30.3–63.5%). After a median follow-up of 42.2 months (range=31.2–54.3 months), median time to progression was 5.6 months (95% CI=3.9–7.2 months) and median overall survival was 11.3 months (95% CI=8.1–14.4 months). Grade 3 or 4 adverse events include neutropaenia (46.5% of patients), hand–foot syndrome (9.3%), arthralgia (9.3%), and asthenia (4.7%). There was no neutropaenic fever or treatment-related deaths. Paclitaxel and capecitabine combination chemotherapy was active and highly tolerable as a first-line therapy for AGC.

Abstract
OBJECTIVE A phase I/II study of a combination of S-1 and weekly paclitaxel was conducted to determine the maximum tolerated dose (MTD), recommended dose (RD), dose-limiting toxicities (DLTs) and objective response rate (RR) in patients with advanced or recurrent gastric cancer. METHODS S-1 was administered orally at a fixed dose of 80 mg/m(2) per day on days 1-14. Paclitaxel was injected intravenously on days 1, 8, and 15, starting with a dose of 50 mg/m(2). The dose was increased in a stepwise manner. RESULTS In phase I, level 2 (60 mg/m(2)) was considered the MTD, because 2 of 3 patients in level 2 developed DLTs (grade 3 neutropenia and anemia, and grade 4 diarrhea and stomatitis). Therefore, the RD was determined to be level 1 (50 mg/m(2)). In phase II, efficacy and safety were assessed in 18 patients treated with the RD. The RR was 64.7% and the median survival time was 13.5 months. The most severe toxicities were grade 3 leukopenia (5.5%) and grade 3 neutropenia (5.5%). CONCLUSION Our study showed that S-1 combined with 50 mg/m(2) paclitaxel is effective and safe in patients with advanced or recurrent gastric cancer.

Abstract
OBJECTIVE We conducted a phase I study of paclitaxel (PTX), carboplatin (CBDCA), and UFT in chemo-naive patients with advanced non-small cell lung cancer (NSCLC). METHOD Twenty-one chemo-naive patients with advanced NSCLC were enrolled. The study was conducted as a phase I dose-escalation study of various doses of systemic PTX followed by CBDCA on day 1 and oral UFT (400 mg/m2) on days 1-5 and 8-12, with the cycle repeated at 21-day intervals. At least three patients were enrolled in each step. RESULTS The main toxicities were neutropenia and paresthesia, but were tolerable and reversible in all cases. Overall response rate was 57% (12 out of 21). The MTD was not reached at the highest dose level after the first cycle. Given previous recommends of PTX at 225 mg/m2 and CBDCA AUC 6 for two-drug therapy, the recommended dose for the phase II study under our regimen was set at PTX 225 mg/m2 on day 1, CBDCA AUC 6 on day 1, and UFT 400 mg/m2 on days 1-5 and 8-12. CONCLUSION The combination of PTX, CBDCA, and UFT showed promising activity and acceptable toxicity in these chemo-naive patients, supporting the development of this combination as a feasible chemotherapeutic option for advanced NSCLC.

Abstract
This study assessed the clinical activity and safety of twice-weekly paclitaxel and cisplatin combined with 5-fluorouracil and leucovorin (TP-HDFL) in patients with recurrent or metastatic esophageal squamous cell carcinoma. The regimen, composed of paclitaxel 35 mg/m 1-h intravenous infusion on days 1, 4, 8 and 11; cisplatin 20 mg/m 2-h intravenous infusion on days 2, 5, 9 and 12; and 5-flourouracil 2000 mg/m and leucovorin 300 mg/m 24-h intravenous infusion on days 5 and 12; repeated every 21 days. Forty-one patients (median age 51), 15 with de-novo metastatic disease and 26 with recurrent disease, were enrolled. Grades 3-4 neutropenia, leukopenia and diarrhea occurred in 37.8, 29.4 and 14.2% of cycles, respectively. One patient died of invasive fungal infection. Three complete responses, 13 partial response and 13 stable diseases were observed. The intent-to-treat response rate was 39.0% (95% confidence interval: 24-54). The median progression-free and overall survival were 6.3 and 8.9 months (range 1-50+), respectively. Twice-weekly TP-HDFL has the activity and toxicity profile similar to the previously reported same three-drug combination for advanced esophageal cancer.

Abstract
BACKGROUND We aimed to clarify the relationship between the maximum tolerated dose and plasma concentration of paclitaxel in Japanese patients with gastric cancer on a weekly paclitaxel administration regimen. METHODS Thirty-three patients with advanced or recurrent gastric cancer were treated with escalating doses of paclitaxel, administered weekly, along with a fixed dose of 5-fluorouracil or cisplatin. RESULTS The plasma concentration of paclitaxel remained above 8.5 ng/ml for 24 h after administration. The mean area under the curve increased significantly with escalating dosage levels (R = 0.63; P 0.001). At level 4, patients showing dose-limiting toxicity had a significantly higher plasma paclitaxel concentration than patients without it. CONCLUSION The weekly administration of paclitaxel, for which a single dose is about one-third of the dose for a tri-weekly treatment regimen, is clinically feasible and appropriate in terms of toxicity and the maintenance of an effective plasma concentration.

Abstract
PURPOSE Conventional chemotherapy for urothelial carcinoma, such as methotrexate, vinblastine, doxorubicin and cisplatin, is associated with significant toxicity. We have previously reported a low toxicity and yet moderately active regimen containing weekly infusional cisplatin and high dose 5-fluorouracil/leucovorin for advanced urothelial carcinoma. We tested the efficacy and toxicity of adding paclitaxel to that regimen. MATERIALS AND METHODS Between April 2000 and December 2004, 44 patients with a median age of 66 years with metastatic urothelial carcinoma were enrolled. The paclitaxel, cisplatin and high dose 5-fluorouracil/leucovorin regimen consisted of 70 mg/m2 paclitaxel daily as a 1-hour infusion on days 1 and 8, 35 mg/m2 cisplatin daily as a 24-hour infusion on days 2 and 9, 2,000 mg/m2 5-fluorouracil daily and 300 mg/m2 leucovorin daily as a 24-hour infusion on days 2 and 9. The cycles repeated every 21 days. A total of 25 patients (64%) had a creatinine clearance of 35 to 60 ml per minute. RESULTS A total of 210 cycles (mean 4.8 per patient) were administered. Of the 40 patients eligible for response evaluation 11 (28%) and 19 (48%) were complete and partial responders with an overall response rate of 75% (95% CI 61 to 89). Median overall and progression-free survival in the whole group was 17.0 (95% CI 13.7 to 20.3) and 8.3 months (95% CI 6.4 to 10.2), respectively. Two-year disease-free survival was 15%. Grade 3 or 4 anemia, leukopenia and thrombocytopenia occurred at 23, 30 and 12 cycles, respectively. Nonhematological toxicity included infection, vomiting and diarrhea, etc. There were 2 treatment related deaths. CONCLUSIONS Paclitaxel, cisplatin and high dose 5-fluorouracil/leucovorin is an active regimen against metastatic urothelial carcinoma which has an acceptable toxicity profile.

Abstract
Both paclitaxel and S-1 are effective against gastric cancer, but the optimal regimen for combined chemotherapy with these drugs remains unclear. This phase I/II study was designed to determine the maximum tolerated dose (MTD), recommended dose (RD), dose-limiting toxicity (DLT), and objective response rate of paclitaxel in combination with S-1. S-1 was administered orally at a fixed dose of 80 mg m-2 day-1 from days 1 to 14 of a 28-day cycle. Paclitaxel was given intravenously on days 1, 8, and 15, starting with a dose of 40 mg m-2 day-1. The dose was increased in a stepwise manner to 70 mg m-2. Treatment was repeated every 4 weeks unless disease progression was confirmed. In the phase I portion, 17 patients were enrolled. The MTD of paclitaxel was estimated to be 70 mg m-2 because 40% of the patients given this dose level (two of five) had DLT. The RD was determined to be 60 mg m-2. In the phase II portion, 24 patients, including five with assessable disease who received the RD in the phase I portion, were evaluated. The median number of treatment courses was six (range: 1-17). The incidence of the worst-grade toxicity in patients given the RD was 28 and 8%, respectively. All toxic effects were manageable. The response rate was 54.1%, and the median survival time was 15.5 months. Our phase I/II trial showed that S-1 combined with paclitaxel is effective and well tolerated in patients with advanced gastric cancer.

Abstract
We conducted a phase II study to determine the activity and tolerability of weekly paclitaxel, 5-fluorouracil (5-FU) and folinic acid plus granulocyte colony-stimulating factor (G-CSF) support in anthracycline-pre-treated or -resistant metastatic breast cancer patients. The phase II study was designed following the Simon optimal-two stage method. Patients received paclitaxel 80 mg/m, folinic acid 10 mg/m and bolus infusion of 5-FU 300 mg/m every week plus G-CSF on day 3 for 24 consecutive weeks in the absence of disease progression. From May 1998 to May 2000, 51 patients entered the study. Patients received a median relative dose intensity of 97.5% (range 81-100%). No severe toxicities were observed. Seven patients (14%) experienced neutropenia grade 2. Seven patients (14%) experienced grade 2 anemia. Two patients (4%) experienced severe asthenia. Three out of 50 evaluable patients [6%, 95% confidence interval (CI) 2-12.6%] showed a complete response, whereas 23 (46%, 95% CI 32.2-59.8%) had a partial response, with an overall response rate of 52% (95% CI 38.2-65.8%). In addition, eight patients (15.7%) had stable disease. In the 13 patients untreated for metastatic disease, the overall response rate was 92.3% (CI 77.8-100), with one complete response and 11 partial responses (84.6% CI 65-100%). In the whole group, the median time to progression and overall survival were 8 (range 1-18) and 14 months (95% CI 11-17), respectively. Thus, in metastatic breast cancer patients pre-treated with anthracyclines, the weekly administration of paclitaxel, 5-FU and folinic acid with G-CSF support seems to be extremely tolerable and active.

Abstract
BACKGROUND Paclitaxel and capecitabine have demonstrated a synergic effect and significant antitumor activity in patients with advanced breast cancer. A weekly schedule of paclitaxel obtained a response rate of 50-68% in advanced breast cancer and less serious side-effects. PATIENTS AND METHODS Thirty-two patients with advanced breast cancer pretreated with chemotherapy were enrolled in a dose-finding trial to determine the maximum tolerated dose (MTD) and the dose-limiting toxicity (DLT) of paclitaxel given on days 1, 8 and 15 of each cycle combined with capecitabine given twice daily from day 1 through day 14, every 21 days. Three patients were recruited at one of six dose levels (paclitaxel 70-100 mg/m2, capecitabine 1650-2500 mg/m2). RESULTS Thirty-two patients were accrued and 31 were evaluated for toxicity. One DLT has been experienced at level VI as diarrhea grade 3. We determined dose level V as the MTD, but we recommend dose level IV for phase II studies (capecitabine 1250 mg/m2 orally twice daily plus paclitaxel 80 mg/m2 intravenously weekly), owing to cumulative toxicity at level V. The objective response rate was 43%. CONCLUSIONS Weekly paclitaxel plus capecitabine is a safety and active chemotherapy in previously treated metastatic breast cancer.

Abstract
OBJECTIVE A dose-escalation study of weekly paclitaxel combined with S-1, a novel oral fluoropyrimidine, was performed to determine the maximum tolerated dose (MTD), the recommended dose (RD) and the dose-limiting toxicities (DLTs) in advanced gastric cancer. PATIENTS AND METHODS Twelve patients were enrolled. S-1 was given orally at a fixed dosage of 40 mg/m(2) b.i.d. for 14 consecutive days, followed by a 1-week rest. Paclitaxel was scheduled to be given intravenously on days 1 and 8 at a dose of 50, 60, 70 or 80 mg/m(2), depending on the DLTs. Treatment was repeated every 3 weeks. A pharmacokinetic study was conducted in an additional 5 patients on days 7 and 8 during the first course given at the RD. RESULTS The MTD of paclitaxel was presumed to be 60 mg/m(2), because 50.0% of patients (2/4) developed DLTs (mainly grade 3 anorexia). DLT was observed in 1 out of 8 patients at a dose of 50 mg/m(2). Therefore, the RD of paclitaxel was estimated to be 50 mg/m(2). The preliminary response rate was 62.5% (5/8) at the RD. There were no significant pharmacokinetic interactions between S-1 and paclitaxel. An adequate plasma paclitaxel concentration for an antineoplastic effect was achieved with weekly doses of 50 mg/m(2). CONCLUSION Weekly paclitaxel combined with S-1 was demonstrated to exhibit a tolerable toxicity profile with therapeutic plasma concentration at the dose of 50 mg/m(2). This regimen could represent a novel and low toxic combination for advanced gastric cancer.

Abstract
The aim of the current study was to determine the maximum tolerated dose (MTD) and the dose limiting toxicity (DLT) of a combination of paclitaxel and S-1 in patients with advanced gastric cancer. Fifteen patients were enrolled. The dose for S-1 was set at 80 mg/m2/day (days 1-14), while the dose for paclitaxel increased by 10 mg/m2 for every three patients, with a starting dose of 100 mg/m2 and was given biweekly on day 1 and 15. There was no severe toxicity (grade 4) recorded in patients receiving up to 120 mg/m2 of paclitaxel. Leukopenia/neutrophilia with grade 1 to 3 occurred in six patients up to level 3. At 130 mg/m2 of paclitaxel, grade 4 leukocytopenia and neutropenia events and grade 3 diarrhea developed in one out of three patients. One patient in another group of three patients that were enrolled at level 3, developed grade 4 granulocytopenia with fever (a body temperature higher than 38 degrees C) and grade 3 leukocytopenia. Eight patients, out of a total of 15, showed a partial response, resulting in an objective response rate of 53%. Five patients received gastrectomy. Median survival time was 428 days and the 1 year survival rate was 53%. Biweekly paclitaxel/S-1 combination chemotherapy could be safely used for the treatment of advanced gastric cancer. The recommended doses for a phase II study with paclitaxel and S-1 are 120 mg/m2 and 80 mg/m2, respectively.

Abstract
OBJECTIVE A phase I study of weekly intravenous paclitaxel combined with a fixed dose of S-1, a dihydropyrimidine-dehydrogenase-inhibitory oral fluoropyrimidine, was conducted for patients with advanced or recurrent gastric cancer (ARGC). Endpoints of this study were to examine the toxicity profile OF this regimen and to determine the recommended dose (rd) of paclitaxel. METHODS S-1 was fixed at a dose of 80 mg/m(2) per day and was administered for 2 weeks (days 1--14) followed by a 2-week rest. Two dose levels of paclitaxel (level 1: 60 mg/m(2), level 0: 50 mg/m(2)) were studied. Paclitaxel was infused over 1 h on days 1, 8, and 15. Plasma sampling was performed to characterize the pharmacokinetics and pharmacodynamics of paclitaxel in some patients. Fifteen patients were enrolled (6 patients in level 1, and 9 patients in level 0). Dose-limiting toxicities were defined as grade 4 hematological (including grade 3 febrile neutropenia) and grade 3 non-hematological (except anorexia, nausea, vomiting and depilation) toxicities. RESULTS Three of 6 patients in level 1 developed grade 4 neutropenia or grade 3 febrile neutropenia, and 1 of them also showed grade 3 diarrhea, which settled the maximum-tolerated dose at this level. At level 0, 2 of 9 patients developed grade 4 neutropenia or grade 3 febrile neutropenia, and the RD of paclitaxel for this protocol was set at this level. Pharmacologic studies demonstrated the persistence of significant serum paclitaxel levels over 24 h after drug administration at both levels. Objective responses according to Response Evaluation Criteria in Solid Tumors were observed in 3 of 6 patients who had measurable disease. CONCLUSION A combination of S-1 and weekly paclitaxel was feasible and well tolerated, and is suggested to produce a worthwhile response in ARGC. These results warrant further investigation, and a phase II study has already been started.

Abstract
BACKGROUND The clinical outcome of gastric cancer patients has been improved by combination of 5-fluorouracil (5-FU) and paclitaxel (PXL). However, the optimal schedule of this combination has not been determined. METHODS The efficacies of sequential administrations of 5-FU and PXL on the gastric cancer cell line MKN45 were investigated using a WST-8 colorimetric assay. The cell cycle distribution of each drug was evaluated by flow-cytometry. Furthermore, the mechanism of antitumor activity enhancement by the administration sequence was investigated by western blotting. RESULTS MKN45 cell growth was significantly inhibited by each drug in a dose- and time-dependent manner. The cytotoxicities of PXL followed by 5-FU were significantly greater than those of 5-FU followed by PXL. The flow-cytometric analysis revealed that PXL exposure caused viable cell accumulation in G2/M phase in a dose-dependent manner. Western blotting showed that PXL exposure followed by 5-FU up-regulated Chk1 and Wee1 protein expressions until PXL removal and 5-FU exposure, when these expressions gradually decreased to their basal levels. 14-3-3sigma protein expression was significantly up-regulated upon PXL treatment followed by 5-FU. Interestingly, Mad2 protein expression with PXL treatment followed by 5-FU gradually increased after the PXL removal and 5-FU exposure. CONCLUSIONS PXL followed by 5-FU administration may be the optimal sequence for treatment of gastric cancer. The enhanced viable cell accumulation after PXL pretreatment may be related to G2 arrest. After PXL removal and 5-FU exposure, the cells progressing to M phase may undergo cell death by mitotic catastrophe due to DNA damage caused by 5-FU exposure.

Abstract
As TS-1 and docetaxel (TXT) have different mechanisms of antitumor activity, the combination therapy is expected to have a higher response. Human gastric cancer xenografts SC-2, St-40, and SC-4 inoculated into nude rats were treated with TS-1 alone (TS-1 12 mg/kg/day, day 1-14), TXT alone (TXT 2 mg/kg/day, day 1 or day 8), and combination of both drugs. TS-1 alone showed antitumor activity against three tumors (growth inhibition rate (IR): SC-2 (38.6 and 40.5%), St-40 (54.5%), SC-4 (55.1%)). TXT was effective with minimal toxicity, especially on day 1 of administration (IR at day 1 administration: SC-2 (51.7%), St-40 (42.1%), SC-4 (46.3%)). In the combined TS-1 and TXT group, antitumor activity increased at day 1 and at day 8 TXT administration (IR at day 1 administration: SC-2 (68.4%), St-40 (72.5%), SC-4 (76.0%)). Weight loss of TS-1 and day 1 TXT administration was the same as that of TS-1 alone. TS-1 and TXT showed no pharmacokinetic interaction. Compared with 5-fluorouracil and cisplatin treatment, combined therapy with TS-1 and TXT showed the same antitumor activity and toxicity. Combined therapy with TS-1 and TXT showed enhanced antitumor activity compared with monotherapy of each drug. The outpatient-based treatment of this combination is worth investigating.

Abstract
Introduction The aim of the study was to evaluate the activity of a combination of doxorubicin (Dox), paclitaxel (Pacl) and 5-fluorouracil (5-FU), to define the most effective schedule, and to investigate the mechanisms of action in human breast cancer cells. Methods The study was performed on MCF-7 and BRC-230 cell lines. The cytotoxic activity was evaluated by sulphorhodamine B assay and the type of drug interaction was assessed by the median effect principle. Cell cycle perturbation and apoptosis were evaluated by flow cytometry, and apoptosis-related marker (p53, bcl-2, bax, p21), caspase and thymidylate synthase (TS) expression were assessed by western blot. Results 5-FU, used as a single agent, exerted a low cytotoxic activity in both cell lines. The Dox→Pacl sequence produced a synergistic cytocidal effect and enhanced the efficacy of subsequent exposure to 5-FU in both cell lines. Specifically, the Dox→Pacl sequence blocked cells in the G2-M phase, and the addition of 5-FU forced the cells to progress through the cell cycle or killed them. Furthermore, Dox→Pacl pretreatment produced a significant reduction in basal TS expression in both cell lines, probably favoring the increase in 5-FU activity. The sequence Dox→Pacl→48-h washout→5-FU produced a synergistic and highly schedule-dependent interaction (combination index < 1), resulting in an induction of apoptosis in both experimental models regardless of hormonal, p53, bcl-2 or bax status. Apoptosis in MCF-7 cells was induced through caspase-9 activation and anti-apoptosis-inducing factor hyperexpression. In the BRC-230 cell line, the apoptotic process was triggered only by a caspase-dependent mechanism. In particular, at the end of the three-drug treatment, caspase-8 activation triggered downstream executioner caspase-3 and, to a lesser degree, caspase-7. Conclusion In our experimental models, characterized by different biomolecular profiles representing the different biology of human breast cancers, the schedule Dox→Pacl→48-h washout→5-FU was highly active and schedule-dependent and has recently been used to plan a phase I/II clinical protocol.

Abstract
OBJECTIVE We conducted a phase I trial of escalating doses of weekly paclitaxel (Taxol) in combination with a fixed systemic administration of 5-fluorouracil (5-FU) in patients with advanced or metastatic gastric cancer. METHODS Patients with advanced or recurrent gastric cancer were treated with escalating doses of weekly paclitaxel as a 60 min intravenous (i.v.) infusion, along with a fixed dose of continuous 5-FU infused over 5 days. Plasma sampling was performed to characterize the pharmacokinetics and pharmacodynamics of paclitaxel. RESULTS Eighteen patients received combination therapy at four dose levels of weekly Taxol, ranging from 60 to 90 mg/m2/week. Dose-limiting toxicities > grade 3 were observed at the 90 mg/m2/week dose level. Toxicities included anemia, neutropenia, thrombocytopenia, nausea and alopecia. Two episodes of grade 4 neutropenia occurred in two of the three patients receiving this dose. At each dose level, pharmacological studies documented the persistence of significant serum paclitaxel levels over 24 h after drug administration. The maximum tolerated dose (MTD) for this regimen was 90 mg/m2/week of paclitaxel for 3 weeks plus 600 mg/m2/day of continuous 5-FU for 5 days. CONCLUSIONS The combination of weekly paclitaxel and 5-FU demonstrated an acceptable toxicity profile and feasible pharmacokinetic results suggesting its practical applicability. Based on these findings, the recommended dose and schedule for phase II study of combination chemotherapy is paclitaxel 80 mg/m2/week x 3 over 4 weeks, and continuous 5-FU 600 mg/m2/day x 5 days every 4 weeks.

Abstract
Pemetrexed is a novel multitargeted antifolate with significant clinical activity against a variety of tumors. We studied the schedule-dependent cytotoxic effects of pemetrexed in combination with paclitaxel in vitro to improve our understanding of how this combination might be used clinically. Human lung cancer A549 cells, breast cancer MCF7, ovarian cancer PA1, and colon cancer WiDr cells were exposed to both pemetrexed and paclitaxel in vitro. Cell growth inhibition after 5 days was determined and the effects of drug combinations were analyzed by the isobologram method (Steel and Peckham). Simultaneous exposure to pemetrexed and paclitaxel for 24 h produced antagonistic effects in A549 and PA1 cells, additive/antagonistic effects in MCF7 cells, and additive effects in WiDr cells. Pemetrexed for 24 h followed by paclitaxel for 24 h produced synergistic effects in A549 and MCF7 cells and additive effects in PA1 and WiDr cells, while the reverse sequence produced additive effects in all four cell lines. Cell cycle analysis supported these observations. Our findings suggest that the simultaneous administration of pemetrexed and paclitaxel is suboptimal. The optimal schedule of pemetrexed in combination with paclitaxel is the sequential administration of pemetrexed followed by paclitaxel, and this schedule should be assessed in clinical trials for the treatment of solid tumors.

Abstract
Purpose The goal of this multicenter, open-label phase II study was the clinical evaluation of combination therapy with the oral fluoropyrimidine capecitabine and the taxane paclitaxel in patients with metastatic breast cancer (MBC). Patients and Methods Forty-seven patients with MBC received oral capecitabine at 1,650 mg/m2/d (825 mg/m2 twice daily) on days 1 through 14, and intravenous infusion of paclitaxel at 175 mg/m2 on day 1 of each 21-day treatment cycle. Treatment continued until disease progression, intolerable toxicity, or patient's decision to discontinue. Patients (35 to 76 years old) had a median Karnofsky performance status of 90%. Forty-four patients (94%) received study treatment as first-line therapy for metastatic disease. Results Objective responses occurred in 24 (51%) patients; seven (15%) complete responses and 17 (36%) partial responses. Stable disease lasting 180 days or more was observed in nine (19%); the clinical response rate was 70%. Median duration of response was 12.6 months, median time to disease progression was 10.6 months, and median overall survival time was 29.9 months. The most common treatment-related adverse events, regardless of severity, were alopecia, hand-foot syndrome, nausea, and fatigue. Neutropenia (15%), alopecia (13%), and hand-foot syndrome (11%) were the only grade 3 or 4 treatment-related adverse events that occurred in more than 10% of patients. Conclusion The combination of capecitabine plus paclitaxel is a highly active and generally well-tolerated regimen for first-line treatment of MBC.

Abstract
BACKGROUND S-1 (TS-1) is a novel oral anticancer drug. Because of the excellent results of phase II studies, we continued to prescribe S-1 for advanced or recurrent gastric cancer after we participated in the phase I and II studies. METHODS Twenty-nine patients with advanced or recurrent gastric cancer were treated with S-1. Clinicopathological features, survival, and adverse reactions were analyzed. RESULTS One course of treatment consisted of 40, 50, or 60 mg/body twice a day for 28 days followed by withdrawal for 2 weeks. The mean number of treatments was 3.6 courses (range, 1-12 courses). The response rate was 37.9% (11 partial responses [PRs] in 29 patients). Although the response rate of patients who did not receive prior chemotherapy was 47.6% (10 PRs in 21 patients), that of patients with prior chemotherapy was 12.5% (1 PR in 8 patients). The median survival time was 14.1 months, and that of patients who responded to treatment was 22.1 months, which was significantly longer than that of nonresponder patients. One-year and 2-year survivals in the 29 patients were 50.2% and 24.3%, respectively. Adverse reactions were noted in 17 of 29 patients, and the most frequent one was leukocytopenia. Only 2 patients experienced grade 3 leukocytopenia and neutrocytopenia. CONCLUSION Because of the high response rate and low incidence of severe adverse reactions, S-1 is a first-line chemotherapy that can be used for outpatients, especially for patients without prior chemotherapy. As the response rate for patients with prior chemotherapy was low, combined therapy with S-1 is worth evaluating for these patients.

Abstract
OBJECTIVES To determine the maximum-tolerated dose (MTD) and dose-limiting toxicity (DLT) of both docetaxel and 5-fluorouracil (5-FU) when administered weekly in a regimen of docetaxel, 5-FU/leucovorin and cisplatin (DFLP) for 2 consecutive weeks every 3 weeks. PATIENTS AND METHODS A total of 31 patients with chemo-naive, advanced adenocarcinoma of the stomach were enrolled in the study. Cisplatin and leucovorin dosages were fixed throughout the study at 30 and 300 mg/m2, respectively. 5-FU dosage was fixed at 1,600 mg/m2 while docetaxel was evaluated at weekly 1-hour infusion dosages of 30, 40 and 50 mg/m2 to determine the MTD. Cisplatin, 5-FU and leucovorin were administered together as a 24-hour continuous infusion following docetaxel. Weekly 5-FU dosages of 1,600, 2,000 and 2,400 mg/m2 were then evaluated after setting the docetaxel dosage at the MTD. RESULTS A total of 95 chemotherapy cycles were administered, with a median of three cycles per patient. The MTD of docetaxel was defined at 40 mg/m2. At a docetaxel dosage of 50 mg/m2 per week, the dose-limiting events of grade 4 febrile neutropenia and grade 3 hypomagnesemia occurred. With fixation of docetaxel to 40 mg/m2, the DLT for 5-FU was found at 2,400 mg/m2 per week. This incurred grade 4 neutropenia such that the MTD of 5-FU was defined at 2,000 mg/m2. Grade 3/4 neutropenia occurred in 14 patients (45%), with 2 patients developing febrile neutropenia. Grade 2 and 3 hypomagnesemia and hypokalemia occurred in 9 (41%) and 4 (18%) patients, respectively, of the first 22 patients treated with a 24-hour infusion of cisplatin and 5-FU/leucovorin immediately following docetaxel. Following a change in the cisplatin administration schedule to a 3-hour infusion after 5-FU/leucovorin infusion, no such complications were observed in 9 subsequently treated patients. Grade 2 diarrhea was recorded in 11 patients (35%). Grade 2/3 asthenia occurred in 9 patients (30%), which resolved after correction of electrolyte disorders. Twenty-six patients were assessable for response analysis. There were 2 (7.8%) complete and 14 (53.8%) partial responses, with the overall response rate being 61.5% (95% confidence interval, 41.5-81.6%). Responses were observed at all dose levels. CONCLUSION Two consecutive weeks of DFLP infusions every 3 weeks appear to be an active regimen with a tolerable toxicity profile in advanced gastric cancer. For further phase II studies, the recommended dose for this combination is 40 mg/m2 of docetaxel and 2,000 mg/m2 of 5-FU per week.

Abstract
The aim of this study was to evaluate the toxicity and efficacy of combination chemotherapy with weekly 24-h continuous infusion of 5-fluorouracil (5-FU)/folinic acid, weekly paclitaxel and 3-weekly cisplatin in patients with unresectable, locally advanced or metastatic gastric adenocarcinoma. Between November 1999 and November 2001, 29 chemotherapy-naive patients (13 male and 16 female) with a median age of 56 years (range 22-72) were consecutively enrolled at three centers. 5-FU 2 g/m2 was given weekly over 24 h i.v. preceded by folinic acid 500 mg/m2 as a 2-h infusion. Paclitaxel 80 mg/m2 was administered as a 1-h infusion weekly and cisplatin 50 mg/m2 as 1-h infusion on days 8 and 29. Six weeks of therapy (days 1, 8, 15, 22, 29 and 36) followed by 1 week of rest was considered one cycle. A median of 3 cycles (range 1-5) was administered to 29 patients with a total of 73 cycles applied. All patients were assessable for toxicity and survival, 28 patients were assessable for response (one patient received less than one complete cycle and could not be evaluated for response). Four patients (14%) obtained a complete response and 10 patients (34%) a partial response (overall response rate 48%, 95% CI 29-68%). Seven patients (24%) had stable disease. Seven patients (24%) had progressive disease during or within 4 weeks after treatment. The median progression-free and overall survival times were 8 months (range 1-23) and 11 months (range 1-23), respectively. Overall toxicity was acceptable. Hematological toxicity was favorable with only one patient (3%) experiencing WHO grade 3/4 leukocytopenia and one patient (3%) WHO grade 3/4 anemia. Non-hematologic WHO grade 3/4 toxicities included alopecia in 19 (66%), nausea/vomiting in six (21%), diarrhea in six (21%), neurotoxicity grade 3 in three (10%) and infection in three (10%) patients. A total of 42 applications (10%) (range 0-5) had to be postponed and dose reductions of at least one drug was necessary in 37% of applications. In three patients (10%) treatment was stopped because of toxicity. All patients were treated on an outpatient basis. Thus, the combination of weekly paclitaxel, cisplatin and continuously infused 5-FU/folinic acid appears to be a highly active regimen for the treatment of patients with advanced gastric cancer. Compared with our previous experience with the same combination of drugs but using paclitaxel at 175 mg/m2 given every 3 weeks, the protocol with weekly application of paclitaxel 80 mg/m2 shows a reduced incidence of hematologic toxicity, particularly leukopenia. Other organ toxicities apart from a slightly higher incidence of peripheral neuropathy were comparable between the two treatment protocols. Efficacy with a response rate of 50% was well preserved by this weekly regimen.

Abstract
PURPOSE Capecitabine and docetaxel have demonstrated preclinical antitumor synergy. This synergy is thought to occur from docetaxel-mediated upregulation of thymidine phosphorylase (dThdPase), an enzyme responsible for the relative tumor selectivity of capecitabine. On the basis of the time-dependency and transiency for this upregulation, we performed a phase I study of capecitabine in combination with weekly docetaxel. We hypothesized that weekly docetaxel would result in sustained dThdPase expression and that capecitabine administration at times of maximum dThdPase upregulation would increase the therapeutic index for this combination. PATIENTS AND METHODS Patients with advanced solid malignancies received docetaxel on days 1, 8, and 15, and capecitabine bid on days 5 to 18, every 4 weeks. Docetaxel was fixed at 36 mg/m(2)/wk, whereas capecitabine was escalated in successive patients cohorts. RESULTS Sixteen patients received 77 courses at capecitabine doses from 950 to 1,500 mg/m(2)/d. The most common toxicities were hand-foot syndrome, diarrhea, nausea/vomiting, and asthenia. Grades 3 to 4 hematologic toxicities were infrequent and no treatment-related hospitalizations occurred. Three of three patients treated at 1,500/36 mg/m(2) capecitabine/docetaxel developed grade 3 hand-foot syndrome or diarrhea during either their first or second course, whereas only two of 13 patients at 1,250/36 mg/m(2) doses developed significant toxicity. Antitumor responses (n = 7) occurred in patients with hepatocellular, non-small-cell lung, and chemotherapy-refractory breast, bladder, and colorectal carcinomas. Prolonged stabilizations occurred in patients with metastatic mesothelioma (n = 2), chemorefractory non-small-cell lung carcinoma, and bronchioloalveolar carcinoma. CONCLUSION Capecitabine in combination with weekly docetaxel is well tolerated. Recommended doses are capecitabine 1,250 mg/m(2)/d (625 mg/m(2) bid) with docetaxel 36 mg/m(2)/wk. The acceptable toxicity profile in this dose schedule, and the antitumor activity observed, warrant further evaluation of this regimen.
