Combination Chemotherapy with Cisplatin and Chloroquine: Effect of Encapsulation in Micelles Formed by Self-Assembling Hybrid Dendritic-Linear-Dendritic Block Copolymers. Int J Mol Sci 2021; 22:ijms22105223. [PMID: 34069278 PMCID: PMC8156097 DOI: 10.3390/ijms22105223] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2021] [Revised: 05/09/2021] [Accepted: 05/11/2021] [Indexed: 12/11/2022] Open
Abstract
Clinical outcomes of conventional drug combinations are not ideal due to high toxicity to healthy tissues. Cisplatin (CDDP) is the standard component for many cancer treatments, yet its principal dose-limiting side effect is nephrotoxicity. Thus, CDDP is commonly used in combination with other drugs, such as the autophagy inhibitor chloroquine (CQ), to enhance tumor cell killing efficacy and prevent the development of chemoresistance. In addition, nanocarrier-based drug delivery systems can overcome chemotherapy limitations, decreasing side effects and increasing tumor accumulation. The aim of this study was to evaluate the toxicity of CQ and CDDP against tumor and non-tumor cells when used in a combined treatment. For this purpose, two types of micelles based on Pluronic® F127 hybrid dendritic–linear–dendritic block copolymers (HDLDBCs) modified with polyester or poly(esteramide) dendrons derived from 2,2′-bis(hydroxymethyl)propionic acid (HDLDBC-bMPA) or 2,2′-bis(glycyloxymethyl)propionic acid (HDLDBC-bGMPA) were explored as delivery nanocarriers. Our results indicated that the combined treatment with HDLDBC-bMPA(CQ) or HDLDBC-bGMPA(CQ) and CDDP increased cytotoxicity in tumor cells compared to the single treatment with CDDP. Encapsulations demonstrated less short-term cytotoxicity individually or when used in combination compared to the free drugs. However, and more importantly, a low degree of cytotoxicity against non-tumor cells was maintained, even when drugs were given simultaneously.

Abstract
Polymer therapeutics has gained prominence due to an attractive structural polymer chemistry and its applications in diseases therapy. In this review, we discussed the development and capabilities of N-(2-hydroxypropyl) methacrylamide (HPMA) and HPMA-drug conjugates in cancer therapy. The design, architecture, and structural properties of HPMA make it a versatile system for the synthesis of polymeric conjugations for biomedical applications. Research suggests that HPMA could be a possible alternative for polymers such polyethylene glycol (PEG) in biomedical applications. Although numerous clinical trials of HPMA-drug conjugates are ongoing, yet no product has been successfully brought to the market. Thus, further research is required to develop HPMA-drug conjugates as successful cancer therapeutics.

Abstract
PURPOSE This study evaluated the efficacy and toxicity of combination chemotherapy with paclitaxel, oxaliplatin, 5-fluorouracil and leucovorin (POFL) in patients with recurrent or metastatic gastric cancer. METHODS One hundred and thirty-eight patients with histologically confirmed recurrent or metastatic gastric adenocarcinoma were treated with the POFL regimen: paclitaxel at a dose of 135 mg/m2 as a 3-hour intravenous infusion on day 1, oxaliplatin 85 mg/m2 and leucovorin 400 mg/m2 as an intravenous infusion over 2 hours on day 1, followed by 5-fluorouracil 2,400 mg/m2 as an infusion over a 46-hour period on 3 consecutive days, in a 2-week cycle. RESULTS Twelve patients could not be evaluated for response because of the absence of any measurable lesions or early discontinuation of therapy, so responses were assessed in 126 patients. The overall objective response rate was 56.3% (95% CI, 47.5%-64.9%). The median time to progression was 6.7 months (95% CI, 5.8-7.6 months), and the median overall survival was 12.6 months (95% CI, 11.3-13.9 months). The most common grade 3 and 4 toxicities were neutropenia (50.7%), peripheral neurotoxicity (16.7%) and alopecia (27.5%). CONCLUSIONS Combination chemotherapy with POFL offers a new, active and safe approach to the treatment of recurrent or metastatic gastric cancer.

Abstract
Combination chemotherapy is widely exploited for enhanced cancer treatment in the clinic. However, the traditional cocktail administration of combination regimens often suffers from varying pharmacokinetics among different drugs. The emergence of nanotechnology offers an unparalleled opportunity for developing advanced combination drug delivery strategies with the ability to encapsulate various drugs simultaneously and unify the pharmacokinetics of each drug. This review surveys the most recent advances in combination delivery of multiple small molecule chemotherapeutics using nanocarriers. The mechanisms underlying combination chemotherapy, including the synergistic, additive and potentiation effects, are also discussed with typical examples. We further highlight the sequential and site-specific co-delivery strategies, which provide new guidelines for development of programmable combination drug delivery systems. Clinical outlook and challenges are also discussed in the end.

Abstract
The cross-administration of nanocarriers modified by poly(ethylene glycol) (PEG), named PEGylated nanocarriers, a type of combination therapy, is becoming an increasingly important method of long-term drug delivery, to decrease side effects, avoid multidrug resistance, and increase therapeutic efficacy. However, repeated injections of PEGylated nanocarriers induces the accelerated blood clearance (ABC) phenomenon, prevents long circulation, and can cause adverse effects owing to alterations in the biodistribution of the drug. Although the nature of the ABC phenomenon that is induced by repeated injections of PEGylated nanocarriers has already been studied in detail, there are few reports on the immune response elicited by the cross-administration of PEGylated nanocarriers. In this study, we investigated the ABC phenomenon induced by the intravenous cross-administration of various PEGylated nanocarriers, including PEGylated liposomes (PL), PEG micelles (PM), PEGylated solid lipid nanoparticles (PSLN), and PEGylated emulsions (PE), in beagle dogs. The results indicated that the magnitude of the immune response elicited by the cross-administration was in the following order (from the strongest to the weakest): PL, PE, PSLN, PM. It is specifically PEG in the brush structure that elicits a significant immune response, in both the induction phase and the effectuation phase. Furthermore, the present study suggests that there is a considerable difference between the effect of repeated injections and cross-administration, depending on the colloidal structure. This work is a preliminary investigation into the cross-administration of PEGylated nanocarriers, and our observations can have serious implications for the design of combination therapies that use PEGylated vectors.

Abstract
Local advanced gastric carcinoma has a very poor prognosis. When a T4 gastric carcinoma has invaded the surrounding tissues and organs, curative resection is unlikely. We present here a case of a 63-year-old woman with a T4 unresectable gastric adenocarcinoma. She underwent two 3-week cycles of docetaxel/cisplatin/fluorouracil chemotherapy, followed by radical gastric resection. Each cycle consisted of 75 mg/m2 docetaxel and 75 mg/m2 cisplatin on day 1, and 200 mg/m2 leucovorin and 500 mg/m2 fluorouracil on days 1 through 5. The patient exhibited a complete histologic response. Our results indicate that docetaxel/cisplatin/fluorouracil neoadjuvant chemotherapy is a promising method of treatment for advanced gastric cancer.

Abstract
PURPOSE This study evaluated the efficacy and safety of adjuvant chemotherapy with the docetaxel plus cisplatin and 5-fluorouracil (5-FU) (DCF) regimen in patients with gastric cancer. PATIENTS AND METHODS Thirty-two patients with gastric or gastroesophageal junction cancer were enrolled in this study after undergoing radical resection. The patients received the following chemotherapy: docetaxel (60 mg/m(2)) on day 1, cisplatin (12 mg/m(2) per day) on days 1 to 5, and 5-FU (2500 mg/m(2)) continuous infusion for 120 hours, repeated every 3 weeks for six cycles. The primary end point was disease-free survival (DFS). RESULTS The median DFS was 17.0 months. The 1-year DFS was 72%, and the 2-year DFS was 37.5%. The median overall survival was 28.0 months. Using univariate analysis, the technique of lymph node dissection was a predictor for postoperative relapse. The median DFS was 15.0 months in the D1 group and 18.0 months in the D2 group (P = .043). The most frequent grade 3/4 adverse events were neutropenia (56.25%), diarrhea (9.38%), nausea (6.25%), and vomiting (6.25%); 12.5% of patients developed febrile neutropenia. There were no chemotherapy-related deaths. CONCLUSIONS The modified DCF regimen is an effective adjuvant chemotherapy in gastric cancer. Hematologic toxicity was frequent but manageable. This regimen merits further investigation.

Abstract
Gastric cancer represents one of the most common cancers internationally. Unfortunately the majority of patients still present at an advanced stage, and despite advances in diagnostic and treatment strategies, outcomes still remain poor with high mortality rates despite a decline in incidence. Whilst the utility of classical chemotherapy agents has been explored thoroughly (and continues to be investigated, alone or in various combinations), advances have been slow and the efficacy of these agents has reached a plateau. As such, the focus of recent study has shifted toward developing a greater understanding of the molecular biology of carcinogenesis and the cancer cell phenotype, and, in turn, the development of rationally designed drugs that target molecular aberrancies in signal transduction pathways specific to gastric cancer. These targets include circulating growth and angiogenic factors, cell surface receptors, and other molecules that comprise downstream intracellular signalling pathways, including receptor tyrosine kinases. Therapeutic advances in this area significantly lag behind other solid organ malignancies such as breast and colorectal cancer. This article reviews the role of targeted therapies in gastric cancer, including rationale and mechanism of action, current and emerging data, as single-agent therapy or in combination regimens. A recently published randomized phaseIII trial supporting the use of trastuzumab, an anti-human epidermal growth factor receptor 2 (HER2)/neu monoclonal antibody, in a selected population of patients is discussed. Therapies that have been evaluated in phase II trials are also reviewed, as well as promising new therapies currently being investigated in preclinical or phase I studies. There is optimism that targeted therapies, whether as single-agent therapy or in combination with traditional therapies, including chemotherapy, radiotherapy and surgery, may yet have an impact on improvement of the overall prognosis of gastric cancer.

Abstract
This study evaluated the efficacy and safety of docetaxel, cisplatin and 5-fluorouracil/leucovorin as neoadjuvant chemotherapy before surgery (NCT group; n = 29) compared with postoperative chemotherapy alone (non-NCT group; n = 26) in the treatment of Borrmann type IV gastric carcinoma. Primary tumour response rate, surgical parameters, incised-edge residue rate, lymphatic metastasis status and side-effects were evaluated. The overall response rate was 58.6% in the NCT group, which included three (10.3%) patients in complete remission and 14 (48.3%) patients in partial remission. The postoperative pathological complete response rate was 6.9% (two patients) in the NCT group. NCT was associated with a significant increase in the radical resection rate and a significant decrease in the rate of incised-edge residues, compared with postoperative chemotherapy alone. Side-effects due to NCT were minimal and resolved with appropriate treatment. There were no chemotherapy-related deaths in either group. In conclusion, docetaxel, cisplatin and 5-fluorouracil/leucovorin was an effective and well-tolerated NCT regimen for Borrmann type IV gastric cancer.

Abstract
BACKGROUND Our previous phase I study provided evidence that weekly paclitaxel, cisplatin, and bolus 5-fluorouracil (weekly PCF) was effective and well tolerated in patients with advanced gastric cancer. This study was conducted to confirm the efficacy and toxicity of weekly PCF. METHODS Eligibility criteria were as follows: pathological confirmation; measurable lesion(s); and no history of treatment with taxanes, platinum-based compounds, or intravenous 5-fluorouracil (1 regimen of pre-treatment with oral 5-fluorouracil agents was allowed). Paclitaxel (80 mg/m(2), 1 h), cisplatin (25 mg/m(2), 2 h), and 5-fluorouracil (600 mg/m(2), bolus) were administered on days 1, 8, and 15, every 4 weeks. RESULTS Between March 2006 and May 2009, 46 patients were enrolled and 45 were assessed. Eighteen had a history of pre-treatment with oral 5-fluorouracil agents. The response rate was 56% [95% confidence interval (CI) 41-70%]. Median progression-free survival was 160 days (95% CI 145-214 days). Median overall survival was 552 days (95% CI 350-843 days). Grade 3-4 major adverse reactions observed were neutropenia (76%), leucopenia (38%), anaemia (27%), febrile neutropenia (22%), exacerbation of performance status (16%), and anorexia (13%). CONCLUSION A weekly PCF regimen is promising for advanced gastric cancer, although it is associated with moderate hematological and minimal non-hematological toxicities.

Abstract
The discovery of new molecular targets and the subsequent development of novel anticancer agents are opening new possibilities for drug combination therapy as anticancer treatment. Polymer-drug conjugates are well established for the delivery of a single therapeutic agent, but only in very recent years their use has been extended to the delivery of multi-agent therapy. These early studies revealed the therapeutic potential of this application but raised new challenges (namely, drug loading and drugs ratio, characterisation, and development of suitable carriers) that need to be addressed for a successful optimisation of the system towards clinical applications.

Abstract
A comprehensive review of phase I and phase II clinical trials of paclitaxel and paclitaxel-containing chemotherapy regimens for advanced gastric cancer was performed. Response rates, median progression-free survivals, and median overall survivals were examined, together with the treatment regimens and the numbers of patients registered in each trial. Although paclitaxel monotherapy produced considerable improvement in tumor response and prognosis, combination doublet or triplet chemotherapy with fluoropyrimidines and/or platinum compounds showed better results than the paclitaxel monotherapy. With regard to the schedule of paclitaxel administration, weekly injection seemed to show less toxicity and better results than administration every 3 weeks. Adjuvant therapies, chemoradiation therapies, and paclitaxel treatment for gastric ascites were also investigated and are discussed.

Abstract
PURPOSE Feasibility and efficacy of four different adjuvant radiochemotherapy regimens in patients with completely resected gastric cancer were evaluated in consecutive cooperative phase II trials using different 5-fluorouracil (5-FU)-based combination chemotherapies (CTX) and 5-FU-enhanced radiotherapy. METHODS Between 2000 and 2005, 157 patients with completely resected gastric adenocarcinoma were included. The study design was based on two cycles of CTX and irradiation with 45 Gy plus concomitant 5-FU 225 mg/m(2) per 24 h between these two cycles. CTX cycles consisted of 5-FU, folinic acid (FA), cisplatin plus paclitaxel (FLPP); 5-FU, FA and cisplatin (FLP); 5-FU, FA and irinotecan (FLI); or 5-FU, cisplatin plus docetaxel (FPD). RESULTS Median follow-up for all four trials was 18 months (range, 1-64) without significant difference between the four regimens: FLPP 30 months (2-46+), FLP 18 months (1-64+), FLI 15 months (1-26), FPD 10 months (5-19+). Treatment associated toxicity was tolerable and did not differ significantly between the four CTX regimens. Across all patients grade (3/4), toxicities during the first cycle/chemoradiation/second cycle consisted of leukocytopenia 4%/2%/30%, anorexia 5%/10%/6%, diarrhea 6%/1%/3%, nausea 2%/7%/2%. Early death occurred in one patient due to Pneumocystis carinii pneumonia. Median progression free survival was 23 months for FLPP, 18 months for FLP, 14 months for FLI, 9 months for FPD (not significant). One-year-overall survival rates were 95% for FLPP, 82% for FLP, 94% for FLI, 86% for FPD. CONCLUSION Adjuvant radiochemotherapy in patients with gastric cancer can be safely given continuous infusion of 5-FU at 225 mg/m(2) per day. In addition, a variety of 5-FU-based multiagent chemotherapy regimen with defined activity in gastric cancer appears both safe and effective when given prior and after radiochemotherapy in this setting.

Abstract
The management of gastric cancer remains a challenge. In recent years, the most important advances have been achieved in the adjuvant setting for patients with locally advanced disease, where significant survival benefits have been demonstrated for both perioperative chemotherapy and adjuvant chemoradiotherapy. These findings have changed the standard of care for patients with resectable disease. In the setting of metastatic gastric cancer, the development of new cytotoxic regimens must consider the balance between efficacy and toxicity in patients whose overall prognosis is poor. Major advances in recent years include the development of orally administered fluoropyrimidine analogues, which can be used in place of intravenous fluorouracil, and the addition of newer agents such as oxaliplatin and docetaxel, which have demonstrated efficacy in patients with advanced disease. Targeted therapies have had a major impact on the management of certain malignancies, and while their evaluation in the treatment of advanced gastric cancer remains early, it is likely that these agents will continue to be developed and studied in combination with chemotherapy. This article reviews recent advances in the use of chemotherapy for advanced gastric cancer. Targeted therapies, their mechanisms of action and emerging data supporting their use in gastric cancer are also discussed. The two randomized phase III trials supporting adjuvant therapy for locally advanced, resectable gastric cancer are discussed in detail, together with strategies for future trials in this area. Overall, there remains optimism that further incremental gains will be achieved with future studies combining chemotherapy, radiotherapy and targeted therapies, both in the adjuvant and metastatic disease settings.

Abstract
PURPOSE To investigate the efficacy and safety of combination chemotherapy with biweekly paclitaxel plus infusional 5-fluorouracil and leucovorin in the treatment of patients with advanced or metastatic gastric cancer. PATIENTS AND METHODS Chemonaive patients with histologically confirmed advanced or recurrent inoperable gastric cancer were enrolled in the present study. Treatment consisted of paclitaxel (75 mg/m(2)) and leucovorin (40 mg/m(2)) as a 2-h intravenous infusion, followed by 5-fluorouracil (2,400 mg/m(2)) as a 46-h continuous infusion. Cycles were repeated every 2 weeks. RESULTS Thirty patients were enrolled in this study. There were 12 partial responses, giving an overall response rate of 40.0%. At a median follow-up of 10.6 months, the median time to progression and median overall survival were 3.9 and 8.8 months, respectively. The most common hematological toxicity was grade 1-2 anemia, which was seen in 83.3% of patients. No grade 4 leukopenia, thrombocytopenia, or anemia was noted. The most common non-hematological toxicity was anorexia, which was seen in 70% of patients, although grade 3 anorexia was noted in only 10% of cases. There was no severe treatment-related morbidity or death. CONCLUSION Combination chemotherapy consisting of biweekly paclitaxel plus infusional 5-fluorouracil and leucovorin was effective and well tolerated in patients with advanced gastric cancers.

Abstract
The aim of this study was to investigate the efficacy and safety of combination chemotherapy with weekly paclitaxel and 5-fluorouracil (5-FU) as first-line treatment in patients with advanced or recurrent gastric carcinoma. A total of 65 patients were treated with the following regimen, administered every 28 days; 5-FU 600 mg/m2 by 24-hour continuous infusion from days 1 through 5, and weekly paclitaxel 80 mg/m2 by 3-hour intravenous infusion on days 8, 14, and 21. A total of 272 cycles were conducted with a median of 4 (2-13) cycles per case. Out of 57 patients with measurable disease by RECIST criteria, there were 2 complete responses (3.5%), 20 partial responses (35.1%) and 25 cases with stable disease (43.9%). The overall response rate was 38.6% (95%CI: 26.0-51.2%). The median survival time and 1-year survival rates were 329 days and 47.4%, respectively. Both hematologic and non-hematologic toxicities were well tolerated.

Abstract
PURPOSE The aim of this study was to investigate the efficacy and safety of the combination chemotherapy of paclitaxel, infusional 5-fluorouracil (5-FU) and leucovorin (FLT regimen) in advanced gastric cancer. The primary end point was the time to progression (TTP). METHODS Patients with evaluable disease with or without measurable lesions received 175 mg/m2 paclitaxel on day 1 followed by 20 mg/m2 leucovorin and 24-h infusion of 5-FU 1,000 mg/m2 (day 1-3) repeated every 3 weeks. RESULTS Sixty patients were enrolled. The median TTP and overall survival duration were 13 and 60 weeks, respectively. One-year survival rate was 53.3%. Of the 50 patients with measurable lesion, the overall response rate was 31.7%. The most common grade 3-4 adverse event was neutropenia (61.7%). CONCLUSION The FLT regimen showed an efficacy comparable to other regimens of cisplatin or anthracycline combinations with the advantage of remarkably low non-hematological toxicity. These data about the efficacy of this regimen need confirmation in a phase III trial.

Abstract
Chemotherapy is of crucial importance in advanced gastric cancer patients, in order to obtain palliation of symptoms and improve survival. The most extensively studied drugs as single agents are 5-fluorouracil, cisplatin, doxorubicin, epirubicin, mitomycin C and etoposide. Newer chemotherapeutic agents include the taxanes (docetaxel and paclitaxel), oral fluoropyrimidines (capecitabine and S-1), oxaliplatin and irinotecan. Randomised trials comparing monotherapy with combination regimens have consistently shown increased response rates in favour of combination regimens, whereas only marginally improved survival rates were usually found. Several combination therapies have been developed and have been examined in Phase III trials. However, in most cases, they have failed to demonstrate a survival advantage over the reference arm. There is no internationally accepted standard of care, and uncertainty remains regarding the choice of the optimal chemotherapy regimen. The objective of this article is to review the present literature available on major Phase II - III clinical trials, in which patients suffering from advanced gastric cancer were treated with cytotoxic chemotherapy.

Abstract
Gastric cancer is the second most frequent cancer in the world. Approximately 84% of patients with gastric cancer will have advanced disease and median survival of these patients without chemotherapy is only 3-4 months. "Classical" chemotherapy regimens, mainly CF (cisplatin plus infusional 5FU) and ECF (cisplatin plus infusional 5FU plus Epirubicin) obtain responses in 20-40% of the patients and improve quality of life. Nevertheless, duration of these responses is short with very few complete responses. Median time to tumor progression (TTP) with these regimens is only about 4-5 months and median survival does not exceed 7-10 months. Moreover, benefit seems to be limited to patients with good performance status and treatment toxicity and discomfort are not negligible, specially that of regimens with cisplatin or infusional 5FU. Trying to improve these results, the incorporation of new drugs has been explored. Among the new combinations, the more developed ones are those with Docetaxel (DCF), oxaliplatin (EOX, FLO), Capecitabine (EOX, cisplatin-Xeloda) and irinotecan (ILF). We have final results from Phase III trials that suggest that all these regimens could have a role in the treatment of these patients but survival is still very poor and toxicity remains important. It would be interesting to investigate other new combinations and the incorporation of drugs directed against new therapeutic targets in this setting. It would be of utmost interest that these clinical trials would also explore clinical and molecular prognostic and predictive factors.

Abstract
PURPOSE Since a weekly administration of paclitaxel has demonstrated a sustained efficacy and more favorable toxicity profile than a 3-weekly administration for various solid tumors, the present study was conducted to evaluate the efficacy and safety of a combination regimen of weekly paclitaxel plus cisplatin in patients with advanced gastric cancer. PATIENTS AND METHODS Patients with previously untreated metastatic or recurrent, measurable gastric cancer received intravenous paclitaxel 100 mg/m(2) plus cisplatin 35 mg/m(2) on days 1 and 8 based on a 3-week cycle. RESULTS Fifty-two patients were enrolled in the current study. Two complete responses and 17 partial responses were confirmed, giving an overall response rate of 36.5%. At a median follow-up of 8.5 months, the median time to progression and median overall survival was 6.0 and 10.8 months, respectively. Grade 3 neutropenia occurred in ten patients, while no grade 4 neutropenia or febrile neutropenia was observed. The most common non-hematologic toxicity was nausea (grade 1/2, 56.9%). There were no treatment-related deaths. CONCLUSION A weekly paclitaxel and cisplatin combination was found to be well-tolerated and effective in patients with advanced gastric cancer. Accordingly, this regimen can be regarded as an important first-line treatment option for advanced gastric cancer.

Abstract
BACKGROUND This study evaluated the efficacy and safety of docetaxel, epirubicin, and 5-fluorouracil (5-FU) [DEF] as treatment for locally advanced unresectable or metastatic gastric cancer. METHODS Thirty-seven patients participated in the study (median age, 56 years; range, 22-73 years); Eastern Cooperative Oncology Group performance status [PS], 0-2). Docetaxel 75 mg/m2 IV (day 1), 5-FU 500 mg/m2 IV (days 1-3), and epirubicin 50 mg/m2 IV (day 1) were administered every 3 weeks for six cycles. RESULTS In total, 20/37 patients (54%) completed six treatment cycles. Thirteen patients (35%; 95% confidence intervals [CI], 20% to 51%) had an objective response; 1 patient (3%) achieved a complete response and 12 patients (32%) achieved partial responses. Stable disease was observed in 7 patients (19%) and progressive disease in 5 patients (14%). Twelve patients (32%) were unevaluable. Clinical benefit (based on PS, weight gain, and analgesic consumption) was observed in 11 patients (30%). Median follow-up was 41 months (range, 26-53 months), median time to progression was 6.6 months (range, 0.5-29.2 months), median overall survival was 10.7 months (range, 7.0-14.6 months), and 1-year survival was 40%. The regimen was well tolerated. Grade 3-4 febrile neutropenia occurred in 8 patients (22%; 6% of cycles) and grade 3-4 neutropenia in 1 patient (1% of cycles). The most frequent grade 3-4 toxicities were alopecia (11% of cycles), diarrhea (4% of cycles) and vomiting (2% of cycles); grade 1-2 asthenia and fatigue occurred in 43% of cycles. CONCLUSION DEF is effective in the treatment of advanced gastric cancer, and has a good safety profile.

Abstract
PURPOSE A phase I study of TCF therapy, which consists of paclitaxel (TXL: Taxol) + cisplatin (CDDP) + 5-fluorouracil (5-FU), in advanced gastric cancer patients was performed to determine the recommended dose (RD) for a phase II study by checking the dose-limiting toxicity (DLT) and maximum-tolerated dose (MTD) of 5-FU above the fixed dose of TXL and CDDP. METHODS The doses of TXL and CDDP were fixed at 80 and 25 mg/m(2), respectively, while that of 5-FU was increased by 100 mg/m(2 )in each cohort from 300 mg/m(2) (level 1) to a maximum of 600 mg/m(2) (level 4). One cycle consisted of administration of these agents once per week for 3 weeks, every 4 weeks. RESULTS A total of twelve eligible patients were included in this study. At level 1, two of three cases showed grade 3 leukopenia. At level 2, one of three cases showed grade 4 neutropenia (recovered within 3 days), and another one case showed grade 3 neutropenia. At level 3, one of three cases showed grade 3 neutropenia, and at level 4, one of three cases showed grade 4 neutropenia (recovered within 3 days), with grade 3 neutropenia in the other two cases. Even at the highest dose administered, none of the patients showed DLT. Moreover, no non-hematological toxicity judged to be DLT was observed through all levels. Six of the twelve patients had measurable disease, and the overall response rate was 83%. CONCLUSIONS Although the MTD level was not determined, based on the observed efficacy and the results of other clinical trials, the recommended doses of TXL, CDDP, and 5-FU for the TCF regimen were set as 80, 25, and 600 mg/m(2), respectively, and a phase II study to investigate the clinical effectiveness and safety of this regimen has now begun.

Abstract
Cancers of the upper gastrointestinal tract are a common cause of worldwide morbidity and mortality. The prognosis for patients with these cancers remains poor and only a minority of patients are cured. Systemic therapy has been used to treat patients with advanced disease but outcomes have not improved dramatically in the past few decades. Newer, more effective agents are desperately needed, and agents such as the taxanes (docetaxel and paclitaxel), irinotecan, oxaliplatin and capecitabine have recently shown some promise. In addition, molecularly targeted, non-cytotoxic therapies are being evaluated with the hope of improving the available therapeutic options. This article reviews the current clinical data regarding systemic therapy for patients with advanced upper gastrointestinal malignancies.

Abstract
Gastric cancer is the fourth most commonly diagnosed cancer and is the second leading cause of cancer death worldwide. More than 50% of patients undergo surgery, but even after a curative resection, 60% of patients relapse locally or with distant metastases. Despite the fact that many advances have occurred in the management of gastric cancer, it continues to carry a poor prognosis, amplifying the importance of palliative chemotherapy. When compared with best supportive care alone, combination chemotherapy yields a significant advantage in the management of advanced gastric cancer. However, no single regimen has emerged or been accepted as clearly superior over another. Numerous phase II studies have demonstrated promising results with newer agents including irinotecan, docetaxel, capecitabine, S-1, and oxaliplatin. Recently reported phase III results with these agents now demonstrate positive developments in the treatment options for patients with advanced gastric cancer.

Abstract
Metastatic gastric cancer remains a non-curative disease. Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase II and III studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed. Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase III trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116 study, postoperative chemoradiation has been accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease. Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase II studies are showing promising results. Phase III trials are needed.

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
BACKGROUND Paclitaxel has shown promising activity in gastric cancer and has synergism with cisplatin. This study was performed to evaluate the efficacy and toxicity of low-dose paclitaxel (145 mg/m(2)) plus cisplatin chemotherapy in metastatic or relapsed gastric cancer. METHODS Chemotherapy-naïve patients with metastatic or relapsed gastric cancer were enrolled. Paclitaxel 145 mg/m(2) was administered intravenously over 3 h, followed by cisplatin 60 mg/m(2) on Day 1 every 3 weeks in the outpatient setting. RESULTS Of 39 patients enrolled, 17 (44%) had partial responses. Twelve (31%) had stable disease and eight (21%) progressive disease. Two patients (5%) were not evaluable because of early drop-out. The median time to progression was 4.7 months and the median overall survival was 12.1 months. The most common hematologic toxicity was anemia (41%). Grade 3/4 neutropenia and thrombocytopenia developed in 14 and 3%, respectively. The most common non-hematologic toxicities were peripheral neuropathy (43%) and emesis (43%). Grade 3/4 non-hematologic toxicities included emesis (11%), peripheral neuropathy (3%), diarrhea (3%) and hepatotoxicity (3%). CONCLUSIONS Low-dose paclitaxel and cisplatin chemotherapy was active and well-tolerated in chemotherapy-naïve gastric cancer patients. This regimen seems to have comparable efficacy to previously reported higher-dose paclitaxel plus cisplatin-containing regimens and fewer toxicities.

Abstract
To investigate the efficacy and safety of combining weekly paclitaxel with weekly 24-hour infusion of high-dose 5-fluorouracil (5-FU) and leucovorin (LV, folinic acid) in the treatment of patients with advanced gastric cancer. Patients with histologically confirmed recurrent or metastatic gastric cancer were studied. Paclitaxel 80 mg/m2 3-hour intravenous infusion was given on days 1, 8, and 15, and high-dose 5-FU 2,600 mg/m2 plus LV 300 mg/m2 24-hour intravenous infusion (HDFL) was given on days 2, 9, and 16, repeated every 4 weeks. Between August 1997 and August 2003, 30 patients were enrolled. The median age was 58 years (range: 37-70). Eighteen patients (60.0%) had recurrent or metastatic disease and 12 patients had de novo metastatic disease. Among the 27 patients evaluable for tumor response, 2 achieved complete response and 9 achieved partial response, with an overall response rate of 40.7% (95% confidence interval, CI: 22-61%). Eleven of the 21 patients without prior exposure to HDFL-containing regimens responded (response rate: 52.4%, 95% CI: 29-74%), while none of the 6 patients who had previously failed HDFL-containing regimens responded (p value = 0.054 by Fisher's exact test). All 30 patients were evaluated for survival and toxicities. Median time to progression and overall survival were 6 and 10 months, respectively. Major grade 3-4 toxicities were neutropenia in 12 patients (40.0%), diarrhea in 10 patients (33.3%), and stomatitis in 3 patients (10.0%). Grade 1-2 and 3-4 paclitaxel-related neuropathy developed in 16 (53.3%) and 2 (6.7%) patients, respectively. None of the patients discontinued protocol treatment because of paclitaxel-related neuropathy or developed HDFL-related hyperammonemic encephalopathy. This paclitaxel-HDFL regimen is effective and well tolerated in the treatment of advanced gastric cancer.

Abstract
BACKGROUND The current two studies evaluate the feasibility, toxicity and efficacy of an adjuvant combined modality treatment strategy containing a three to four-drug chemotherapy regimen plus 5-fluorouracil (FU)-based radiochemotherapy. PATIENTS AND METHODS Between December 2000 and October 2003, a total of 86 patients were included in both studies. Patients with completely resected gastric adenocarcinoma including a D1 or D2 lymph node dissection (LND) were eligible. Treatment consisted of two cycles of folinic acid 500 mg/m2, 5-FU 2000 mg/m2 continuous infusion over 24 h once weekly for 6 consecutive weeks, paclitaxel 175 mg/m2 in weeks 1 and 4 and cisplatin 50 mg/m2 in weeks 2 and 5 (FLPP; n=41) or two cycles of the same 5-FU/folinic acid schedule but with cisplatin 50 mg/m2 only in weeks 1, 3 and 5 (FLP; n=45). Radiation with 45 Gy plus concomitantly applied 5-FU 225 mg/m2/24 h was scheduled in between the two cycles. RESULTS Patients characteristics were: D1/D2 LND FLP group 53%/42%; FLPP group 27%/68%; stage distribution: UICC stages III/IV(M0) FLP group 63% and FLPP group 66%. Median follow-up was 10 months (3-25) for FLP and 18 months (2-51) for FLPP patients. CTC grade 3/4 toxicities during the first cycle/chemoradiation/second cycle of FLP: granulocytopenia 3%/0/27%, anorexia 6%/10%/8%; diarrhea 8%/0/4%, nausea 3%/0/4%; FLPP: granulocytopenia 0/0/37%, anorexia 5%/11%/6%; diarrhea 5%/0/3, nausea 3%/8%/0%; early death in one patient due to Pneumocystis carinii pneumonia. Projected 2-year progression-free survival was 64% (95% CI 56% to 68%) for the FLP and 61% (95% CI 42% to 78%) for the FLPP group. CONCLUSIONS Both chemoradiation regimens appear feasible with an acceptable toxicity profile indicating that cisplatin can be added to 5-FU/FA and that even a four-drug regimen can be investigated further in prospective clinical trials in completely resected gastric cancer patients. Treatment should be given in experienced centres in order to avoid unnecessary toxicity.

Abstract
BACKGROUND Although many treatments for advanced gastric cancer have been developed, only poor treatment results have generally been obtained. We performed a prospective study on the combination chemotherapy of paclitaxel and cisplatin (PC). The primary objectives of the study were elucidating the disease response and evaluating the drug regimen's safety. METHODS Patients with metastatic or recurrent gastric cancer received intravenous paclitaxel 175 mg/m2, and cisplatin 70 mg/m2 on day 1. This cycle was repeated every 3 weeks. RESULTS From January 2000 to March 2004, 37 patients from 3 different hospitals were enrolled in this study. A total of 135 treatment cycles (median: 3 cycles) were administered. The responses were evaluable in 34 patients; 24 patients received this regimen as their first-line treatment for metastatic cancer and the other patients received it as their second-line treatment for recurrent cancer. The objective response rate (RR) was 26.5% (95% CI: 11.7-41.3) with two complete responses, and stable disease was observed in 41.1% of the patients. Importantly, an RR of 33.3% (95% CI: 0.6-66.0) was achieved for the eight patients who received this regimen as a first-line treatment. The median follow up duration was 14 months for all the patients, and the median time to progression was 6 months (95% CI: 1.9-10.2). The overall survival time was 8.9 months (95% CI: 7.0-11.0) with a 1-year survival rate of 18.7% (95% CI: 5.6-31.8). The most common toxicity was neutropenia. CONCLUSION PC exhibited promising activity against gastric cancer for the previously untreated patients as a first-line treatment with an acceptable toxicity profile.

Abstract
PURPOSE Based on the synergistic effect in preclinical studies, a phase I clinical trial for the combination of paclitaxel and doxifluridine (an intermetabolite of capecitabine) was performed to determine the recommended dose for the treatment of patients with metastatic gastric cancer. METHODS The dose of paclitaxel was increased from 60 mg/m2 at level 1 to 90 mg/m2 at level 5. It was administered as a 1-h infusion on days 1 and 8. The dose of doxifluridine was fixed at 600 mg/m2 per day up to level 3, and escalated to 800 mg/m2 per day at levels 4 and 5. It was administered orally for 2 weeks. The treatment was repeated every 3 weeks. RESULTS A total of 28 patients were enrolled. No dose-limiting toxicity (DLT) was observed at levels 1 and 2 (paclitaxel 70 mg/m2). A DLT of grade 4 neutropenia lasting for more than 4 days was observed in one patient at level 3 (paclitaxel 80 mg/m2). In addition, the first five of six patients in this group experienced grade 3 neutropenia during the first treatment cycle. A further six patients were added in order to confirm the safety of this dosage level, and no more DLTs except for grade 3 nausea in one patient were observed in the second cohort. No DLT was seen in three patients at level 4 (paclitaxel 80 mg/m2). DLTs (grade 3 neuropathy in one patient and a treatment delay of the second cycle for more than 1 week due to grade 3 neutropenia in another) were observed in two out of six patients at level 5 (paclitaxel 90 mg/m2), and this dose level was determined as the maximum tolerated dose. The tumor response rate was 42% (95% confidence interval 20-67%) in 19 patients with measurable lesions. CONCLUSIONS The recommended dose was determined as 80 mg/m2 of paclitaxel (days 1 and 8) and 800 mg/m2) of doxifluridine (days 1-14) every 3 weeks. The results of this phase I study are encouraging and a phase II trial is thus warranted.

Abstract
We have evaluated the antitumor effects of gefitinib (Iressa, ZD1839) in SNU-1 human gastric cancer cells (hMLH1-deficient and epidermal growth factor receptor-overexpressed) when given alone or as a doublet with oxaliplatin (LOHP), 5-fluorouracil (5-FU) or paclitaxel (PTX). The four drugs showed IC50s ranging from 1.81 nM to 13.2 microM. LOHP and PTX induced G2/M arrest, 5-FU increased S phase, and gefitinib increased G1 in a concentration-dependent manner. The analysis using the previously developed cytostatic TPi model showed that 64 and 80% of the overall growth inhibition was attributed to cell cycle arrest in cells exposed to 7.55 microM of LOHP or 10 nM of PTX for 72 h, respectively. PTX + gefitinib showed greatest synergism as determined by combination index analysis and apoptosis induced by PTX was potentiated by the co-administration of gefitinib. LOHP + gefitinib showed a similar, although to a lesser degree, synergistic effect. This study demonstrates the antitumor activity and the significant cell cycle arrest induced by gefitinib in SNU-1 human gastric carcinoma cells, and its synergistic interaction with LOHP and PTX.

Abstract
AIMS Gastric cancer in Western countries is often diagnosed in an advanced stage and prognosis is poor. We performed a randomised trial with pre-operative FAMTX vs. surgery alone in order to evaluate the effect of pre-operative chemotherapy on resectability and survival. METHODS Patients with proven adenocarcinoma of the stomach were randomised to receive four courses of chemotherapy using 5-Fluorouracil, doxorubicin and methotrexate (FAMTX) prior to surgery or to undergo surgery alone. RESULTS Fifty-nine patients were randomised; 29 patients were allocated to the FAMTX regimen prior to surgery and 30 patients had surgery alone. Resectability rates were equal for both groups. Complete or partial response was registered in 32% of the FAMTX group. With a median follow-up of 83 months the median survival since randomisation is 18 months in the FAMTX group vs. 30 months in the surgery alone group (p=0.17). CONCLUSIONS This trial could not show a beneficial effect of pre-operative FAMTX. Until large randomised studies prove otherwise, adequate surgery without delay is the best treatment for operable gastric cancer.

Abstract
Globally, gastric cancer is one of the most common types of cancer and one of the most frequent causes of cancer-related death. Despite many advances in the diagnosis and treatment of this disease, the prognosis for gastric cancer remains poor, especially in more advanced stages. In metastatic disease, benefits in survival and quality of life have been demonstrated in patients with unresectable or metastatic gastric cancer receiving chemotherapy plus best supportive care versus best supportive care alone. The taxanes, which are among the most promising cytotoxic agents in clinical use, have shown encouraging activity in early-phase studies as single agents and in combination regimens in the treatment of advanced gastric cancer. Recently, interim results of a randomized phase III trial comparing the triplet of docetaxel, cisplatin, and 5-fluorouracil with a standard reference regimen of cisplatin and 5-fluorouracil were reported. Patients treated with the docetaxel-containing regimen had a statistically superior response rate and time to disease progression as well as a clinically significant prolongation of survival. This study underscores the importance of developing new therapeutic options for patients with advanced gastric cancer.
