Abstract
Combinations of topoisomerase I (topo I) poisons and platinum derivatives have synergistic antitumoral effects. However, their clinical development is limited by supra-additive haematological toxicity. The aim of this study was to determine whether sustained doses of topotecan and oxaliplatin could be achieved using a synergistic sequence. 34 advanced cancer patients and 186 cycles were evaluable for toxicity over five dosing levels. Oxaliplatin at 85-110 mg/m(2) was given on day 1, followed by topotecan 0.5-1.25 mg/m(2)/day x 5 from day 1 to 5, every 3 weeks. Plasma pharmacokinetics (PK) of total and ultrafiltrable platinum, total and lactone forms of topotecan were determined in the first cycle. The dose-limiting toxicity (DT) was identified as grade 4 thrombocytopenia. The occurrence of grade 4 thrombocytopenia did not correlate with topotecan PK, but it did with the patient's characteristics. Severe thrombocytopenia was seen in 1/8 of patients without clinical or biological evidence of malnutrition, with a creatinine clearance higher than 1 ml/s, and no more than two previous chemotherapy regimens, while it was seen in 8/10 patients with one of these characteristics (P<0.004). In conclusion, the recommended doses of oxaliplatin 110 mg/m(2) and topotecan 1 mg/m(2)/day, every 3 weeks can be administered to patients with a favourable general status and pretreatment characteristics and a phase II study is worthwhile in ovarian cancer patients.

Abstract
PURPOSE We performed a randomized, double-blind, placebo-controlled trial to assess the efficacy of glutathione (GSH) in the prevention of oxaliplatin-induced neurotoxicity. PATIENTS AND METHODS Fifty-two patients treated with a bimonthly oxaliplatin-based regimen were randomized to receive GSH (1,500 mg/m(2) over a 15-minute infusion period before oxaliplatin) or normal saline solution. Clinical neurologic evaluation and electrophysiologic investigations were performed at baseline and after four (oxaliplatin dose, 400 mg/m(2)), eight (oxaliplatin dose, 800 mg/m(2)), and 12 (oxaliplatin dose, 1,200 mg/m(2)) cycles of treatment. RESULTS At the fourth cycle, seven patients showed clinically evident neuropathy in the GSH arm, whereas 11 patients in the placebo arm did. After the eighth cycle, nine of 21 assessable patients in the GSH arm suffered from neurotoxicity compared with 15 of 19 in the placebo arm. With regard to grade 2 to 4 National Cancer Institute common toxicity criteria, 11 patients experienced neuropathy in the placebo arm compared with only two patients in the GSH arm (P =.003). After 12 cycles, grade 2 to 4 neurotoxicity was observed in three patients in the GSH arm and in eight patients in the placebo arm (P =.004). The neurophysiologic investigations (sural sensory nerve conduction) showed a statistically significant reduction of the values in the placebo arm but not in the GSH arm. The response rate was 26.9% in the GSH arm and 23.1% in the placebo arm, showing no reduction in activity of oxaliplatin. CONCLUSION This study provides evidence that GSH is a promising drug for the prevention of oxaliplatin-induced neuropathy, and that it does not reduce the clinical activity of oxaliplatin.

Abstract
The standard de Gramont (dG) regimen of fortnightly leucovorin, bolus fluorouracil and 22-h infusion of fluorouracil, d1+2, and the same regimen plus oxaliplatin, are effective but also cumbersome. We therefore present simplified 'Modified de Gramont' (MdG) regimens. Forty-six advanced gastrointestinal cancer patients entered a dose-exploring study of MdG, including an expanded cohort of colorectal cancer patients at optimum dose. Treatment (fortnightly) comprised: 2-h i.v.i. leucovorin (350 mg d,l-LV or 175 mg l-LV, not adjusted for patient surface area); bolus fluorouracil (400 mg m(-2)), then ambulatory 46-h fluorouracil infusion (2000-3600 mg m(-2), cohort escalation). Subsequently, 62 colorectal patients (25 unpretreated; 37 fluorouracil-resistant) received MdG plus oxaliplatin (OxMdG) 85 mg m(-2). Fluorouracil pharmacokinetics during MdG were compared with dG. The optimum fluorouracil doses for MdG alone were determined as 400 mg m(-2) bolus + 2800 mg m(-2) 46-h infusion. A lower dose of 400 mg m(-2) bolus + 2400 mg m(-2) infusion which, like dG produces minimal toxicity, was chosen for the OxMdG combination. Fluorouracil exposure (AUC(0-48 h)) at this lower dose is equivalent to dG. With OxMdG, grade 3-4 toxicity was rare (neutropenia 2.8% cycles; vomiting or diarrhoea <1% cycles), but despite this there were two infection-associated deaths. Oxaliplatin was omitted for cumulative neurotoxicity in 17 out of 62 patients. Objective responses in colorectal cancer patients were: 1st-line MdG (22 assessable): PR=36%, NC=32%, PD=32%. 1st-line OxMdG (24 assessable): CR/PR=72%; NC=20%; PD=8%; 2nd line OxMdG (34 assessable): PR=12%; NC=38%; PD=50%. MdG and OxMdG are convenient and well-tolerated. OxMdG was particularly active as 1st-line treatment of advanced colorectal cancer. Both regimens are being further evaluated in the current UK MRC phase III trial.

Abstract
With effective chemotherapy as adjuvant treatment, the survival benefit is clearly achieved for certain (stage III) colorectal cancer patients, though there still exist many unsettled issues including the controversies in the treatment of stage II disease. Advances in the development of a new generation of cytotoxic agents in the past several years have allowed us to move forward from the "fluorouracil-only era" in the treatment of advanced/metastatic colorectal cancer. It is still not very clear how best to minimize toxicity without compromising efficacy of the combination therapy with newer agents, or how to maximize the benefit of chemotherapy (concurrent versus sequential). There are many current ongoing clinical trials designed to address these issues. With better understanding of the signal transduction and molecular biology characteristics of colorectal cancer, and the development of biologic and molecular target agents, the outcomes of patients with colorectal cancer will be improved further. Future clinical trials should be focused on optimizing and individualizing therapy for patients based on their molecular profiles to achieve maximal clinical benefit.

Abstract
For advanced colorectal carcinoma, two new drugs, raltitrexed (TOM) and oxaliplatin (L-OHP), have recently shown interesting results. Preclinical and clinical studies suggest that this combination, because of its favorable toxicity profile, high response rate and convenient schedule of administration, can be administered successfully in this disease. In our phase II study, 37 non pre-treated patients with metastatic colorectal carcinoma were treated with TOM (3 mg/m(2)) and L-OHP (130 mg/m(2)) every 3 weeks. In total, 222 cycles were administered; all patients received at least 2 cycles (median 6, range 2-8). There were two complete and 14 partial responses for an overall response rate of 43% (95% CI 27-69%). The median time to response was 2.5 months (range 2-4) and the median duration was 10.3 months (range 5-18). Twelve of the 23 (52%) patients with symptomatic colorectal cancer were classified as clinical benefit responders for at least 4 weeks during the study period. Treatment was well tolerated, and both acute, essentially hematologic, and cumulative hepatic and neurologic toxicities were manageable and reversible. Response rate and toxic effects observed during this study warrant additional studies comparing this TOM-L-OHP regimen with CPT-11 and/or capacitebine-containing regimens in metastatic colorectal carcinoma.

Abstract
Combination of chemotherapy and surgical resection of metastases is the most promising strategy to improve the fraction of long-term survivors and cured patients in metastatic colorectal cancer. We reproducibly observed evidence of exacerbation of the oxaliplatin-induced neurosensory toxicity following surgery. Total, protein-bound and intra-erythrocytic concentrations of oxaliplatin were measured, whenever possible, immediately prior to surgery and 4, 24 and 48 h following surgical resection. Among 12 patients, seven (58%) patients reported immediate post-operative aggravation of the pre-existing neurotoxicity. At the time of surgery, we detected high intra-erythrocytic platinum concentrations in all patients (median: 1365 micro g/l, range: 820-2968 micro g/l). While ultrafilterable oxaliplatin was not detectable prior to surgery, it could be detected immediately after surgery and during 48 h. These results suggest that patients heavily pretreated with oxaliplatin may experience aggravation of neurotoxicity after surgery, probably through a redistribution of the pool of intra-erythrocytic oxaliplatin biotransformation products into the plasma. This clinical observation might be the consequence of peroperative hemolysis.

Abstract
PURPOSE Until the 1990s, the patient's duration of life was the main measure for determining the value of palliative chemotherapy for colorectal cancer. Quality of life recently appeared as a main end point. The aim of this article is to provide an overview of the instruments used to measure quality of life in patients with metastatic colorectal cancer, to review the published data and to analyse the bias and methodological problems. CURRENT KNOWLEDGE AND KEY POINTS QoL is a multidimensional subjective concept, which can be measured using psychometric instruments. Quality of life measurement has a descriptive and prognostic value. Results from quality of life assessment in randomized trials have given useful information and help patients and physicians to choose between treatment options. More than half of the patients with palliative chemotherapy had at least stabilization of quality of life. Response to chemotherapy and side-effects influence quality of life. Quality of life assessment clearly requires methodological improvement. Missing data are a particularly difficult problem, which should be improved by a better organization. FUTURE PROSPECTS AND PROJECTS Psychometric properties of EORTC QLQ-CR38 et FACT-C should be checked in French language. An international consensus on methods of measurement of quality of life in oncology is warranted to enhance compliance, to better interpret quality of life results et to optimize publications of precise quality of life data.

Abstract
A phase II study was performed to evaluate the clinical efficacy and toxicity of oxaliplatin combined with uracil and tegafur (UFT) in patients with advanced colorectal cancer previously treated with a fluoropyrimidine-based regimen. From January to December 1999, 34 patients were enrolled in this study. Patients received intravenous oxaliplatin 130 mg/m2 on day 1 and daily oral UFT 350 mg/m2 in 3 divided doses for 21 days and repeated every 21 days. Thirty-one of 34 patients were assessable for response and 32 patients for toxicity. Partial response was observed in four patients and stable disease in six patients. The response rate was 12.9% (95% CI, 3.6-29.8%) and median duration of response was 17 weeks. The median overall survival and progression-free survival of all patients were 26 weeks (range, 3-90+ weeks) and 9 weeks (range, 3-56 weeks), respectively. Sensory neuropathy was the most common toxicity, but there was no severe toxicity (>grade II) except for a case of grade III neutropenia. We conclude that oxaliplatin and UFT combination chemotherapy was well tolerated without significant toxicities. The results of this trial will serve as the basis for designing new clinical trials with a different dose or schedule.

Abstract
A 60-year-old woman with a history of unresectable colon adenocarcinoma was treated by chemotherapy with a combination of oxaliplatin with leucovorin and fluorouracil. Progressive dyspnea and bilateral pulmonary interstitial infiltrates developed. Bronchoscopy with bronchoalveolar lavage confirmed pulmonary eosinophilia. Clinical and radiologic aspects of eosinophilic lung disease cleared after cessation of this combination of chemotherapy and did not recur after reintroduction of leucovorin/fluorouracil alone, suggesting that oxaliplatin was the causative agent. Care was taken to rule out other possible causes for eosinophilic pneumonia.

Abstract
The purpose of this study was to evaluate the efficacy and tolerance of a combination of irinotecan, oxaliplatin, and 5-fluorouracil (5-FU)/leucovorin in advanced colorectal cancer (ACC). Twenty-six consecutive patients with ACC and an Eastern Cooperative Oncology Group performance status of 0-2 were treated with a combination of oxaliplatin (120 mg/m2 intravenously [i.v.] for 2 hours) on day 1, irinotecan (250 mg/m2 i.v. for 90 minutes) on day 1, and 5-FU (2600 mg/m2 plus leucovorin 500 mg/m2 i.v. in a 24-hour infusion) on day 1 and 15, every 4 weeks. Five of the patients (19.2%) had shown previous chemoresistance. One hundred sixty-two cycles were administered (median, 6; range, 3-13 cycles). All patients were evaluated for toxicity; 23 were evaluable for response. According to intention-to-treat, the overall response rate was 69.2% (18 patients; 95% CI: 48.2%-85.7%), including 3 complete remissions (11.5%). Four additional patients (15.3%) had stable disease, and only 1 (3.8%) progressed. Major toxicities were neutropenia and diarrhea. Grade 3 neutropenia occurred in 9 patients (34.6%), and grade 4 occurred in 1 patient (3.8%). Grade 3 diarrhea occurred in 8 patients (30.7%) and grade 4 in 1 patient (3.8%). Other toxicities were mild. After a median follow-up of 15.5 months, the median progression-free survival was 14 months. Seventeen patients (65.4%) are still alive, and the median overall survival has not been reached yet. This combination of irinotecan, oxaliplatin, and 5-FU/leucovorin is fairly well tolerated and shows promising activity in ACC. This treatment merits further comparison with other combination regimens.

Abstract
BACKGROUND This multicenter, phase II, open-label study evaluated the antitumor efficacy and safety of oxaliplatin and raltitrexed (Tomudex) in non-pretreated advanced colorectal cancer patients. PATIENTS AND METHODS Seventy-one patients received oxaliplatin 130 mg/m(2) and raltitrexed 3 mg/m(2) intravenously on an outpatient basis every 3 weeks. All patients had histologically proven metastatic colorectal adenocarcinoma, performance status <or=2 and good baseline organ function. Most (56%) had only one disease site. All patients were assessed for safety, and 66 of 69 eligible patients were assessed for response. RESULTS A total of 404 cycles were administered, with a median of six cycles per patient (range 1-12 cycles). Relative dose intensities were 0.98 and 0.98 for oxaliplatin and raltitrexed, respectively. The most common grade 3-4 toxicities (National Cancer Institute Common Toxicity Criteria) among treated patients were as follows: neutropenia (21 patients, 30%), asthenia (eight, 11%), diarrhea (12, 17%), liver function test abnormalities (24, 34%), nausea (nine, 13%) and vomiting (nine, 13%). Two treatment-related deaths occurred (hematotoxicity in one patient and gastrointestinal toxicity in the other) and two further deaths were possibly related to treatment (hepatic dysfunction in one patient and neuropathy in the other). Thirty-seven objective responses (one complete) were obtained [objective response rate 54%; 95% confidence interval (CI) 42% to 65%] in eligible patients. The median response duration was 8.5 months (95% CI 6.7-12.2 months), while median progression-free and overall survival among eligible patients were 6.2 (95% CI 5.1-6.9 months) and 14.6 months (95% CI 11.0-18.9 months), respectively. CONCLUSIONS The present study confirms the feasibility of the raltitrexed plus oxaliplatin combination and its activity in non-pretreated advanced colorectal cancer patients.

Abstract
Following surgical resection of colorectal carcinoma, local recurrence in the tumor bed or in the mesentery remains a frequently encountered problem. Currently there are no recognized standard therapy protocols for the prevention of local recurrence or the treatment of peritoneal carcinomatosis. The aim of our trial was to investigate whether CPT-11 and oxaliplatin could decrease i.p. tumor growth in a basic experimental animal model. Experiments were performed on three groups of animals plus controls. In the first group, the cytostatic agents were applied directly following tumor cell implantation into the peritoneal cavity. In the second group, early postoperative i.p. chemotherapy (days 5, 10 and 15 following surgery) was administered. In the third group, late i.p. chemotherapy (days 15, 20 and 25 after tumor cell transfer) was administered with the intention of reducing a manifest peritoneal carcinomatosis. The trial also set out to describe any side effects observed following i.p. administration. The results indicated that CPT-11 and oxaliplatin were highly effective in reducing i.p. tumor spread after direct i.p intraoperative application. Intraperitoneal administration of CPT-11 or oxaliplatin also decreased i.p. tumor growth after early i.p. chemotherapy. CPT-11 was a little more effective with lower side effects. However, it was clear that it was not possible to treat a manifest peritoneal carcinomatosis in this way.

Twelves CJ, Cassidy J. Which endpoints should we use in evaluating the use of novel fluoropyrimidine regimens in colorectal cancer? Br J Cancer 2002; 86:1670-6. [PMID: 12087448 PMCID: PMC2375398 DOI: 10.1038/sj.bjc.6600341] [Citation(s) in RCA: 6] [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: 12/18/2001] [Revised: 03/21/2002] [Accepted: 03/27/2002] [Indexed: 02/04/2023] Open
Abstract
Although significant advances have been made in the treatment of advanced/metastatic colorectal cancer, 5-fluorouracil (5-FU) still forms the basis of chemotherapy. Recently, new 5-FU schedules and novel fluoropyrimidines have been developed, but there are no trials directly comparing these regimens. The current review describes the mechanisms of action, pre-clinical and phase I/II studies of two oral fluoropyrimidine therapies, capecitabine and uracil with tegafur plus leucovorin. It also compares the phase III studies of these agents with those of the two most popular infusional 5-FU-based regimens: de Gramont and German AIO (The Association of Medical Oncology (AIO) of the German Cancer Society). Both oral and infusional regimens demonstrated similar survival to the Mayo Clinic regimen, a standard treatment for colorectal cancer. Therefore, other endpoints must be examined to decide optimum therapy, including response rates, time to disease progression, tolerability and patients' convenience. All four new therapies demonstrated superior safety profiles compared with the Mayo Clinic regimen. However the uracil with tegafur plus leucovorin regimen was associated with severe diarrhoea and capecitabine with hand-foot syndrome. Patients will not sacrifice efficacy for the convenience of oral therapy alone, therefore the fact that capecitabine achieved superior response rates and equivalent time to disease progression compared with the Mayo Clinic regimen, while uracil with tegafur plus leucovorin produced lower response rates and significantly inferior time to disease progression, is highly relevant in choosing treatment.

Abstract
PURPOSE To evaluate the efficacy and tolerance of irinotecan (CPT-11) in combination with oxaliplatin (L-OHP) plus fluorouracil (5-FU)/leucovorin (LV) (de Gramont regimen) as first-line treatment of metastatic colorectal cancer (MCC). PATIENTS AND METHODS Thirty-one patients with MCC who had not received prior therapy for metastatic disease were enrolled. Their median age was 60 years; performance status (World Health Organization) was 0 in 12, 1 in 14, and 2 in five patients; 19 patients (61%) had prior surgery, and 14 (45%) had adjuvant chemotherapy. CPT-11 was administered on day 1 at 150 mg/m(2) as a 90-minute intravenous (IV) infusion; L-OHP was administered on day 2 at 65 mg/m(2) as a 2-hour IV infusion; and on days 2 and 3, LV 200 mg/m(2) preceded 5-FU administration of 400 mg/m(2)/d initial IV bolus dose followed by 600 mg/m(2)/d 22-hour IV continuous infusion. The regimen was repeated every 2 weeks. RESULTS All patients were assessable for toxicity and 30 for response to treatment. Complete response was achieved in two patients (6.5%) and partial response in 16 (51.6%) (overall response rate, 58.1%; 95% confidence interval, 40.7% to 75.4%); eight patients (25.8%) had stable disease, and five (16.1%) had disease progression. The median duration of response was 9 months, and the median time to disease progression was 13 months. Neutropenia grade 3 to 4 occurred in 14 patients (45%) and febrile neutropenia in two (6%). Diarrhea grade 3 to 4 was observed in 10 patients (32%), neurotoxicity grade 3 to 4 in three (9%), and asthenia grade 3 in two (10%). No treatment-related death has occurred. CONCLUSION The triplet combination of 5-FU/LV + CPT-11 + L-OHP is a highly active regimen with manageable toxicity as front-line treatment in MCC.

Abstract
The goal of the present paper is to review how treatment of advanced colorectal cancer has evolved during the last 10 years and to make some suggestions on how that disease could be managed today. 5-Fluorouracil (5-FU) combined with folinic acid (FA) remains the basis for advanced colorectal cancer treatment. In Europe, infusional 5-FU is considered to be more active and better tolerated than bolus 5-FU. New agents including oral 5-FU prodrugs UFT/FA, and capecitabine, tomudex, irinotecan and oxaliplatin have been shown active in advanced colorectal cancer. At presentation the combination of infusional 5-FU/FA with irinotecan or oxaliplatin is considered to be superior to any of these agents used alone, yielding a median survival of up to 16-19 months. Second-line therapy could further prolong survival in selected patient populations. Eventually chemotherapy could allow curative resection of previously unresectable hepatic and pulmonary metastases.

Abstract
PURPOSE Phase II study evaluating efficacy and safety of combined oxaliplatin/fluorouracil (5-FU) in taxane-pretreated advanced and metastatic breast cancer (ABC) patients. PATIENTS AND METHODS Sixty-four taxane- and anthracycline-pretreated (within 6 months of study entry) women were treated with oxaliplatin 130 mg/m(2) (2-hour intravenous [IV] infusion), day 1, and 5-FU 1,000 mg/m(2)/d (continuous IV infusion) days 1 to 4, every 3 weeks. RESULTS Median patient age was 51 years (range, 34 to 71 years), with a median of two involved organs (range, one to six organs), and metastases in the liver (70%), bone (47%), and lung (34%). Patients had a median of two prior chemotherapy regimens (range, one to six regimens), and 78% had previous hormonal therapy, with clinical taxane and anthracycline resistance in 53% and 34%, respectively. A total of 367 cycles were administered, with a median of six cycles/patient (range, one to 15 cycles). Sixty patients were assessable for response (World Health Organization criteria): 17 partial response, 26 stable disease, and 17 disease progression, giving an overall response rate of 27% (95% confidence interval, 16.3% to 39.1%), and 26% and 36% in taxane- and anthracycline-resistant populations, respectively, all responders having metastatic liver disease. Median time to progression was 4.8 months, and median overall survival was 11.9 months. Four treatment-related serious adverse events occurred, seven patients withdrew because of treatment-related toxicity. Hematotoxicity was prevalent but rarely severe, with grade 3-4 neutropenia, leukopenia, and thrombocytopenia in 34%, 19%, and 16% of patients, respectively, and a single episode of febrile neutropenia. One third of patients developed grade 2-3 peripheral neuropathy (oxaliplatin-specific scale), with grade 3 in only 8%. CONCLUSION This oxaliplatin/5-FU combination is effective with an excellent safety profile in anthracycline/taxane-pretreated ABC patients, showing encouraging activity in patients with anthracycline/taxane-resistance or visceral disease.

Abstract
PURPOSE A phase II trial investigated the activity and toxicity of a bolus administration schedule of oxaliplatin, fluorouracil (5-FU), and leucovorin (LV) therapy in patients with untreated advanced colorectal cancer. PATIENTS AND METHODS Forty-five patients in this multicenter, open, nonrandomized study received oxaliplatin 130 mg/m(2) on the first day of each course and 5-FU and LV 350 mg/m(2) and 20 mg/m(2), respectively, as a daily bolus for 5 days, every 21 days, for a maximum of six courses. RESULTS Partial responses occurred in 18 patients, giving an intent-to-treat response rate of 40.0%. Median time to response was 12.7 weeks; median duration of response was 18.4 weeks. Median progression-free survival was 5.9 months; median survival was 14 months. The independent prognostic factors for improved overall survival were good performance status and negative carcino-embryonic antigen blood level. Incidences of adverse effects were reduced after the 5-FU dose was reduced to 300 mg/m(2). Reversible neurologic toxicity occurred in 44.4% of patients. CONCLUSION Bolus administration of oxaliplatin, 5-FU, and LV as first-line therapy for untreated advanced colorectal cancer is efficacious and safe. In addition to a more favorable safety profile, the 300 mg/m(2) dosage offered improved dose-intensity compared with the initial dosage.

Abstract
Coadministration of eniluracil with 5-fluorouracil (5-FU) allows the oral absorption of small doses of 5-FU, resulting in therapeutic plasma levels. A phase II clinical trial of this combination using a continuous dosing schedule was carried out in patients with metastatic colorectal cancer. Fifty-three previously untreated patients and 46 patients who had received one prior regimen for metastatic disease were enrolled. Patients received 10 mg/m2 of eniluracil and 1 mg/m2 of 5-FU twice daily for 28 days, with cycles repeated after a 7-day rest until progression of disease or prohibitive toxicity. Seven of 53 previously untreated patients had an objective tumor response (13.2%): 1 complete response and 6 partial responses. The mean duration of response was 6.3 months. Only 1 of the 45 evaluable patients in the previously treated group had a partial response, with no complete responses. The duration of response was 3 months. The median progression-free survival was 3.4 months for the previously untreated group and 2.5 months for the previously treated group. Median overall survival was 11.1 months for the previously untreated group and 9.0 months for the previously treated group. Hematologic toxicity was infrequent, with 3 patients experiencing grade 3 toxicity. Incidence of grade 3/4 toxicity included 11 patients with diarrhea, 5 with nausea, and 4 with vomiting. Other common toxicities included anemia and stomatitis, but they were generally mild. This regimen is well tolerated and shows activity in previously untreated patients with metastatic colorectal cancer that is similar to that observed with other 5-FU-based regimens. This regimen has not shown to be effective in patients who have had prior chemotherapy.

Abstract
BACKGROUND To evaluate the safety and efficacy of the novel raltitrexed/oxaliplatin combination (TOMOX) as first-line chemotherapy for patients with advanced colorectal cancer. MATERIALS AND METHODS Previously untreated patients with metastatic colorectal cancer received raltitrexed 3 mg/m2 plus oxaliplatin 100 mg/m2, both intravenously, on day 1 every 3 weeks. Patients were re-evaluated after every third cycle and chemotherapy was continued up to tolerance or disease progression. RESULTS Fifty-eight patients from 13 Italian Group for the Study of Gastrointestinal Tract Carcinomas (GISCAD) centers were accrued from September 1999 to November 2000. According to the intention-to-treat analysis from 58 patients, the overall response rate was 50% [95% confidence interval (CI) 38% to 62%], with three complete responses and 26 partial responses. The median overall survival (44 patients currently alive) was >9 months and the median time to disease progression was 6.5 months (range 1-15 months). The main hematological toxicity was grade III/IV neutropenia, which occurred in 17% of patients, while anemia and thrombocytopenia were uncommon. Grade III/IV non-hematological toxicities were transient transaminitis (17% of patients); asthenia (16% of patients); neurotoxicity (10% of patients) and diarrhea (7% of patients). No toxic death was observed, one patient with grade IV asthenia after the first cycle refused chemotherapy. CONCLUSIONS The results of this study suggest that the TOMOX combination is an effective and well tolerated regimen for the treatment of advanced colorectal cancer. Its ease of administration and patient tolerance warrant further investigation as an alternative to fluoropyrimidine-based regimens with repeated and prolonged fluorouracil infusions.

Abstract
Palliative and adjuvant treatment for colorectal cancer has been, until recently, largely dependent on 5-fluorouracil (5-FU)-based chemotherapy. Oral fluoropyrimidines have been evaluated in the advanced disease setting and they appear to be as effective as 5-FU, but are safer and more convenient for most patients. Irinotecan and oxaliplatin are new cytotoxic agents, which are active in 5-FU-resistant disease, but which may also be combined with 5-FU as initial therapy in advanced disease. Initial combination therapy leads to improved response rates and more prolonged progression-free survival compared with 5-FU monotherapy. Standard regimens for adjuvant therapy usually involve 6 months of chemotherapy using 5-FU and folinic acid. Recent trials of capecitabine, oxaliplatin and irinotecan in the adjuvant setting are ongoing, or have recently completed accrual, and may lead to a change in future clinical practice. Biological therapies are playing an increasing role in the management of colorectal cancer. Farnesyl transferase inhibition, inhibition of the epidermal growth factor receptor (EGFR) and the vascular endothelial growth factor (VEGF) are undergoing evaluation in advanced disease. In the adjuvant setting, both passive and active immunotherapeutic approaches have been studied. In addition, a large trial will evaluate the role of cyclo-oxygenase(COX)-2 inhibitors as adjuvant therapy. Further research is required in order to define the optimal sequence and combination of these different cytotoxic and biological therapies, in order to secure the best possible outcome for various subgroups of patients with both early and advanced stage colorectal cancer.

Abstract
Long-term results after liver resection for colorectal liver metastases show 5-year survival rates between 35 and 40%. However, only a limited number of patients appear to be candidates for resection, far more patients prove to have unresectable disease. Present challenges in liver surgery for colorectal metastases are to improve patient selection, to increase the resectability rate and to improve survival by multimodality treatment approaches. The variables most consistently associated with a poor prognosis and tumour recurrence are tumour-positive resection margins and the presence of extra-hepatic disease. Hence, patient selection and preoperative staging should concentrate on accurate imaging of the liver lesions and the detection of extrahepatic disease. For liver imaging, spiral computed tomography (CT) scan or magnetic resonance imaging (MRI), supplemented by intra-operative ultrasound, are currently regarded as the best methods for evaluating the anatomy and resectability of colorectal liver metastases. Extrahepatic disease should be investigated by spiral CT of the chest and abdomen and when possible by 2-fluouro-2-deoxy-D-glucose-positron emission tomography (FDG-PET). Resection remains the gold standard for the surgical treatment of colorectal liver metastases. In experienced centres, resection is a safe procedure and mortality rates are below 5%. The aim of resection should be to obtain tumour-negative resection margins. Edge cryosurgery should be considered in cases where very close resection margins are anticipated. The role of adjuvant chemotherapy after resection is still controversial, although two recent studies show a clear benefit. For the moment, local tumour ablative therapies such as cryotherapy and radiofrequency therapy should be considered as an adjunct to hepatic resection in those cases in which resection can not deal with all of the tumour lesions. In these cases, there seems a beneficial effect of a combined treatment consisting of resection and local tumour ablation. At this stage, there are no randomised data that local tumour ablation is as effective as resection. For a selected group of patients with unresectable liver metastases, there may be a chance to turn unresectable disease to resectable disease by aggressive neo-adjuvant chemotherapy or portal vein embolisation. For patients with unresectable disease, many different chemotherapy schedules may be used based on systemic drug administration. Regional chemotherapy and isolated liver perfusion should only be used within a study design.

Abstract
Attempts at improving the efficacy of 5-fluorouracil (5-FU) by protracted continuous infusion and/or biochemical modulation have been hindered by the need for indwelling central venous catheters and their associated toxicity. Capecitabine, an oral fluoropyrimidine carbamate, has been rationally synthesized as an inactive precursor that is absorbed intact through the intestinal mucosa and is sequentially converted by an enzymatic cascade involving 3 distinct enzymes to 5'-deoxy-5-fluorocytidine, to 5'-deoxy-5-fluorouridine (5'-DFUR), and finally to 5-FU. Preclinical studies provided evidence of preferential intratumoral conversion of inactive 5'-DFUR to active 5-FU due to the relative overexpression of the final anabolizing enzyme, thymidine phosphorylase, in tumor tissues, with a resultant decrease of 5-FU exposure in normal tissues. The safety of capecitabine and optimal dosing schedules have been explored in phase I/II studies, resulting in the evaluation of the intermittent schedule (1250 mg/m2 twice daily for 14 days, every 3 weeks) in most subsequent clinical trials. Two large randomized phase III studies in patients with metastatic colon cancer established at least equivalent efficacy and improved tolerability with capecitabine compared to the Mayo Clinic bolus 5-FU/leucovorin regimen. The most common treatment-related adverse events are palmar-plantar erythrodysesthesia, diarrhea, and stomatitis, with grade 3/4 events occurring in 17%, 15%, and 2%-8% of patients, respectively. Myelosuppression was minimal. Overall toxicity was easily managed, with a significant reduction in the frequency of hospitalizations and medical resource use. The spectrum of clinical efficacy of capecitabine is expected to encompass other tumor types and administration in the adjuvant setting. As a home-based outpatient regimen, capecitabine represents a safe and effective advance in modern drug development.

Abstract
BACKGROUND Regimens combining oxaliplatin with fluorouracil and folinic acid are standard therapeutic options for patients with metastatic colorectal carcinoma. Oxaliplatin has a good safety profile, although it is responsible for dose-limiting neurotoxicity typically consisting of two distinct clusters of symptoms. Cold-induced distal paresthesiae occur during or shortly after infusion in most patients and are usually transient and mild. A persistent sensory peripheral neuropathy may develop with prolonged treatment, eventually causing superficial and deep sensory loss, sensory ataxia and functional impairment. METHODS The authors report four cases of atypical neurotoxicity induced by oxaliplatin in patients treated for metastatic colorectal carcinoma. Two patients were male and two were female, with an age range of 52-59 years. RESULTS Three patients experienced Lhermitte sign and two experienced urinary retention. In all cases, the cumulative dose of oxaliplatin was higher than 1000 mg (range, 1248-2040 mg). Brain and spinal magnetic resonance imaging was performed in two patients and was normal. Somatosensory evoked potentials were recorded in two patients and suggested cervical dorsal column dysfunction. Symptoms resolved a few weeks after discontinuation of oxaliplatin. CONCLUSIONS Lhermitte sign may be induced via a neurotoxic effect on the ascending axons of these T-shaped neurons. An atonic bladder may be the result of damage to the sensory portion of the sacral reflex arc, either in the dorsal roots, as for example in diabetic neuropathy, or in the posterior columns, as in tabes dorsalis. Alternatively, it may result from a paralysis of the parasympathetic fibers that control the bladder musculature. It is unclear at present whether the micturition difficulties observed in patients in the current series are due to sensory neuropathy or to autonomic neuropathy, event if the former hypothesis seems more likely, as autonomic neuropathy has not been previously observed with oxaliplatin, and its association with cisplatin is exceedingly rare and controversial.

Abstract
The combination of 5-fluorouracil-folinic acid and oxaliplatin has led to a significant improvement of chemotherapy efficacy in advanced pretreated colorectal cancer. The objective of the present study was, considering the oxaplatin-5-fluorouracil-folinic acid combination, to examine the impact of one given drug on the cellular determinants of cytotoxic activity of the other drug. These cellular factors were analysed on the human colon cancer cell line WiDr in clinically relevant conditions of drug exposure ('De Gramont' schedule) with oxaliplatin-folinic acid during 2 h followed by 5-fluorouracil 48 h. The DNA binding of oxaliplatin was significantly reduced by the presence of 5-fluorouracil but this effect was time-dependent and after 50 h the platinum incorporated into DNA was identical in controls and in the drug combination. In the presence of oxaliplatin, there was less formation of FUH(2) which is the first catabolite produced in the cascade of 5-fluorouracil metabolic degradation. The effects of drugs on cell cycle were quite different from one drug to the other with oxaliplatin inducing a shift towards G(2) accumulation and 5-fluorouracil-folinic acid to a greater proportion of cells in G(1)-S. When oxaliplatin and 5-fluorouracil-folinic acid were combined the cell cycle effects were very similar to that of the 5-fluorouracil-folinic acid sequence alone. Oxaliplatin was able to reduce thymidylate synthase activity with a marked impact 28 h after the beginning of cell exposure to the drug. The 5-fluorouracil-folinic acid drug sequence led to a profound reduction in thymidylate synthase activity and this decrease was not markedly enhanced by the presence of oxaliplatin. Regarding apoptosis, changes in mitochondrial membrane permeability were observed in the presence of the tested drugs and the impact of 5-fluorouracil-folinic acid was greater than that of oxaliplatin. The addition of oxaliplatin did not amplify the action of 5-fluorouracil-folinic acid upon mitochondrial membrane permeability change. The presence of oxaliplatin itself did not modify the intracellular concentration of total reduced folates. The fact that oxaliplatin may reduce 5-fluorouracil catabolism could be central in explaining the supra-additive interaction between these drugs.

Abstract
PURPOSE To determine the efficacy and tolerability of combining oxaliplatin with capecitabine in the treatment of advanced nonpretreated and pretreated colorectal cancer. PATIENTS AND METHODS Forty-three nonpretreated patients and 26 patients who had experienced one fluoropyrimidine-containing regimen for advanced colorectal cancer were treated with oxaliplatin 130 mg/m(2) on day 1 and capecitabine 1,250 mg/m(2) bid on days 1 to 14 every 3 weeks. Patients with good performance status (World Health Organization grade 0 to 1) were accrued onto two nonrandomized parallel arms of a phase II study. RESULTS The objective response rate was 49% (95% confidence interval [CI], 33% to 65%) for nonpretreated and 15% (95% CI, 4% to 35%) for pretreated patients. The main toxicity of this combination was diarrhea, which occurred at grade 3 or 4 in 35% of the nonpretreated and 50% of the pretreated patients. Grade 3 or 4 sensory neuropathy, including laryngopharyngeal dysesthesia, occurred in 16% of patients on both cohorts. Capecitabine dose reductions were necessary in 26% of the nonpretreated and 45% of the pretreated patients in the second treatment cycle. The median overall survival was 17.1 months and 11.5 months, respectively. CONCLUSION Combining capecitabine and oxaliplatin yields promising activity in advanced colorectal cancer. The main toxicity is diarrhea, which is manageable with appropriate dose reductions. On the basis of our toxicity experience, we recommend use of capecitabine in combination with oxaliplatin 130 mg/m(2) at an initial dose of 1,250 mg/m(2) bid in nonpretreated patients and at a dose of 1,000 mg/m(2) bid in pretreated patients.

Abstract
OBJECTIVES This phase I, dose-escalation study was conducted to determine the recommended dose of intermittent oral capecitabine in combination with a fixed dose of i.v. oxaliplatin. Secondary objectives included evaluation of the safety profile and antitumor activity. PATIENTS AND METHODS Twenty-three patients with advanced or metastatic solid tumors received a 21-day regimen of oral capecitabine (500, 825, 1000 or 1250 mg/m2 twice daily, days 1-14) in combination with oxaliplatin (130 mg/m2, 2-h i.v. infusion, day 1). Dose-limiting toxicities were determined during the first treatment cycle, and safety and efficacy were evaluated throughout treatment. RESULTS The recommended dosing schedule is oral capecitabine 1000 mg/m2 twice daily (days 1-14) with i.v. oxaliplatin 130 mg/m2 (day 1) in a 21-day treatment cycle. The principal dose-limiting toxicity was diarrhea. The most frequent treatment-related adverse events occurring during the study were gastrointestinal (nausea/vomiting, diarrhea) and neurological (dysesthesia, paresthesia). The majority of treatment-related adverse events were mild to moderate in intensity, and no grade 4 adverse events occurred in the 15 patients treated at or below the recommended dose. The most common grade 3/4 laboratory abnormalities were lymphocytopenia (52% of patients), thrombocytopenia (22%; grade 3 only), neutropenia (17%) and hyperbilirubinemia (17%). Among patients treated at or below the recommended dose level (n = 15), only two patients experienced grade 3 neutropenia and no patients experienced grade 4 neutropenia. Partial tumor responses occurred in six patients (26%), including five of nine patients (55%) with colorectal cancer. All responding patients were pretreated with 5-fluorouracil and four responders had received prior irinotecan. CONCLUSIONS Oral capecitabine with i.v. oxaliplatin is a feasible combination regimen that shows promising antitumor activity in patients with colorectal cancer. There is an ongoing, phase II study to further characterize the safety and efficacy of this combination as first-line therapy for metastatic colorectal cancer, using the recommended dose identified in this study.

Abstract
Unresectable hepatocellular carcinoma (UHCC) is considered a chemoresistant disease. Moreover, because the liver underlies the disease, it decreases the tolerance to anticancer agents. Topotecan has shown some clinical activity in UHCC using the 5 days every 3 weeks schedule but is limited by severe hematotoxicity. Oxaliplatin is a diamino-cyclo-hexane-platin that exhibits in vitro synergy with topotecan. Thirteen UHCC patients received topotecan (0.5-1.5 mg/m(2) /d days 1-5) and oxaliplatin (85-110 mg/m(2) /d, day 1) every 21 days. All patients had liver biology within normal limits; 11 had World Health Organization performance status less than 2. Seven patients had received previous chemotherapy. Nine patients without cirrhosis received a median number of six cycles (range: 3-12). The main dose-limiting toxicity was severe thrombocytopenia observed in three patients and 4% of cycles. One objective response and eight stabilizations were observed. Conversely, among 4 patients with cirrhosis receiving a median number of 2.5 cycles (range: 1-6), severe thrombocytopenia occurred in 2 patients and 25% of cycles. Three patients with progressive disease and one with stabilization were observed. Overall, the median duration of stabilizations was 27 weeks (range: 16-97 weeks). Four of seven patients treated with 1 mg/m(2) /d or more topotecan experienced severe toxicity. These results warrant a phase II study of this combination in noncirrhotic patients with UHCC. The recommended doses for further studies should be 0.5 mg/m(2) /d to 0.75 mg/m(2) /d of topotecan with 85 mg/m(2) of oxaliplatin.

Abstract
PURPOSE Oxaliplatin is a novel platinum compound with clinical activity in several malignancies. Neurotoxicity is dose-limiting and occurs in two distinct forms, an acute neurologic symptom complex that occurs within hours or days of therapy and a chronic, cumulative sensory neuropathy. PATIENTS AND METHODS Patients were treated in a phase I study designed to establish the maximum-tolerated dose of capecitabine given with oxaliplatin. Because of the unusual neurosensory toxicity of oxaliplatin, detailed neurologic examination, needle electromyography (EMG), and nerve conduction studies (NCS) were performed before and the day after oxaliplatin in a subset of 13 patients. Carbamazepine therapy was tried in 12 additional patients to determine whether the neurologic effects might be relieved. RESULTS All patients experienced acute, reversible neurotoxicities with oxaliplatin. Symptoms included paresthesias, dysesthesias, cold hypersensitivity, jaw pain, eye pain, pain in the arm used for drug infusion, ptosis, leg cramps, and visual and voice changes. Serial EMG and NCS revealed striking signs of hyperexcitability in motor nerves after oxaliplatin. In patients who achieved therapeutic levels, carbamazepine did not alter the clinical or electromyographic abnormalities. CONCLUSION The acute neurotoxicity seen with oxaliplatin is characterized by peripheral-nerve hyperexcitability, and the findings are similar to the clinical manifestations of neuromyotonia. Carbamezepine, which provides symptomatic relief in acquired neuromytonia, did not seem to be beneficial. Efforts to identify a successful neuroprotectant strategy would have a major impact on improving patient quality of life and the ability to deliver full doses of oxaliplatin.

Abstract
The aim of this study was to assess in patients with advanced colorectal cancer which factors were associated with short-term survival (6 months or less) and progression to first-line 5-fluorouracil (5-FU) chemotherapy. Three hundred twenty-one consecutive nonselected patients with advanced colorectal cancer were treated with conventional 5-FU-based regimens as first-line treatment from 1988 to 1999. Factors related to patient, tumor, or treatment were analyzed by univariate and multivariate logistic regression analysis by comparing short survivors (SS, those who survived <or=6 months) with those who survived longer than 6 months. The same statistical methods were used to analyze 200 patients, all treated with bolus 5-FU regimens, by comparing who progressed to treatment with those who did not. Sixty-two patients (19.3%) were SS, the remaining 259 patients survived more than 6 months. First-line chemotherapy included 5-FU in all patients; 112 (35%) and 27 (8.4%) patients were offered, after disease progression, second and third-line chemotherapy, respectively. The overall response rate to first-line chemotherapy was 12.9%. No SS patient achieved an objective response. To investigate factors associated with progression to first-line chemotherapy, we considered only those patients treated with bolus 5-FU regimens, to eliminate the variable of regimen used. Ninety-six of them progressed to treatment and 104 did not. At multivariate analysis, SS patients were characterized by the following: right and transverse colon primary (p = 0.006), younger age (p = 0.043), poor performance status (Eastern Cooperative Oncology Group >or= 2) (p = 0.015), elevated (>or=5 microg/l) serum carcinoembryonic antigen (CEA) (p = 0.015), and more than one site of metastatic disease (p < 0.001). Progression to first-line chemotherapy (p < 0.001) was also a strong factor associated with short survival in multivariate analysis; factors predictive of progression were elevated CEA (p = 0.027) and diffuse metastatic disease (p = 0.029). Our data indicate the relevance of some clinical prognostic factors (younger age, poor performance status, elevated CEA, site of primary, number of metastatic sites, resistance to chemotherapy) as independent factors associated with poor survival and progression to first-line chemotherapy in patients with metastatic colorectal cancer treated with conventional 5-FU regimens. Patients identified by these factors as having a poor prognosis and low probability of response to treatment should be considered either for more aggressive regimens or supportive care only: conventional 5-FU treatments do not impact on response or survival.

Abstract
Raltitrexed ('Tomudex') monotherapy is a conveniently administered alternative to 5-fluorouracil (5-FU) in the first-line treatment of advanced colorectal cancer (CRC), and has single-agent activity in a variety of advanced solid tumours. Although both raltitrexed and 5-FU are thymidylate synthase inhibitors, raltitrexed has a specific mode of action and a toxicity profile distinct from 5-FU. The mechanism of action of raltitrexed is also completely different from that of oxaliplatin, irinotecan and other drugs with which it has been combined. These properties, together with preclinical data, suggested that combinations of raltitrexed with 5-FU, other chemotherapeutic agents, or radiotherapy could result in improved therapies for a variety of advanced solid tumours, including advanced CRC. This review outlines the appropriate management of patients treated with raltitrexed, whether as monotherapy or in combination, and discusses the preliminary results of combination studies with raltitrexed in a range of tumour types including advanced CRC, malignant mesothelioma, gastric, pancreatic, head and neck, and non-small-cell lung cancers. Of particular interest is the combination of raltitrexed and oxaliplatin, which has shown promising antitumour effects in first-line treatment of advanced CRC and malignant mesothelioma, a disease that is refractory to chemotherapy.

Abstract
The treatment of patients with metastatic colorectal cancer has changed dramatically over recent years. The more optimal use of 5-fluorouracil (5-FU) in association with folinic acid (FA), the development of new drugs such as irinotecan and oxaliplatin and of the oral fluoropyrimidines, capecitabine and UFT, have contributed to increased therapeutic options and to the improved outcome of patients with metastatic colorectal cancer. It is shown that combination therapy with 5-FU/FA and irinotecan or oxaliplatin is more active than 5-FU/FA in the first-line treatment of advanced colorectal cancer. Irinotecan and oxaliplatin are also active in the second-line treatment of colorectal cancer. The oral fluoropyrimidines seem to have an activity comparable to that of intravenous 5-FU/FA in the first-line treatment of metastatic colorectal cancer. New agents acting on novel targets are under development: epidermal growth factor inhibitors, vascular endothelial growth inhibitors, COX-2 inhibitors and farnesyl transferase inhibitors might play a role in the future in the treatment of colon cancer.

Abstract
Colorectal cancer is still a majorhealth and social problem. However, many important advances in treatment have been made in the last 4 to 5 years, and more optimism is now justified both among clinicians and patients. In surgically resectable disease, adjuvant chemotherapy has been clearly demonstrated as able to increase overall survival in patients with colon cancer Dukes' stage C, whereas the role of medical treatment in patients with Dukes' stage B colon cancer is still controversial. At present, the standard regimen is bolus fluorouracil (5-FU) modulated by folinic acid (leucovorin) for 6 months. For rectal cancer, the best adjuvant treatment seems to be represented by radiotherapy (better if administered preoperatively) combined with chemotherapy (usually based on modulated or continuously infused 5-FU). In advanced disease, many new drugs have recently emerged: the most active regimens are those combining an optimal modality of 5-FU administration (i.e. continuous infusion) and one of the most active innovative compounds (irinotecan or oxaliplatin). The role of the oral drugs (e.g. tegafur/uracil, capecitabine) is still under investigation as is the combination of agents excluding 5-FU. It is now recognised that first-line treatment must be offered to all suitable pa- tients, even though asymptomatic, and that a second-line therapy (chiefly with irinotecan) is of value in many patients with cancer that progresses during treatment with 5-FU. From a strategic point of view, the best sequence of drugs/regimens has not yet been defined, while the duration and timing of chemotherapy is still a matter for clinical research. Finally, there is an increasing interest in the role of biological prognostic factors as an aid to a patient-tailored therapy, both in the adjuvant setting and in advanced disease. To achieve further progress in knowledge in this field, we strongly recommended that more and more patients are included in clinical trials.

Abstract
The relevance of circadian rhythms in irinotecan and oxaliplatin tolerability was investigated with regard to antitumour activity. Mice bearing Glasgow osteosarcoma (GOS) received single agent irinotecan (50 or 60 mg kg(-1) per day) or oxaliplatin (4 or 5.25 mg kg(-1) per day) at one of six dosing times expressed in hours after light onset (3, 7, 11, 15, 19 or 23 hours after light onset). Irinotecan (50 mg kg(-1) per day) and oxaliplatin (4 or 5.25 mg kg(-1) per day) were given 1 min apart at 7 or 15 hours after light onset, or at their respective times of best tolerability (7 hours after light onset for irinotecan and 15 hours after light onset for oxaliplatin) or worst tolerability (15 hours after light onset for irinotecan and 7 hours after light onset for oxaliplatin). Tumour growth rate was nearly halved and per cent increase in estimated life span (% ILS) was - doubled in the mice receiving irinotecan at 7 hours after light onset as compared to 15 hours after light onset (P<0.05). Results of similar magnitude were obtained with oxaliplatin for both endpoints, yet with 7 hours after light onset corresponding to least efficacy and 15 hours after light onset to best efficacy (P<0.05). Irinotecan addition to oxaliplatin proved therapeutic benefit only if the schedule consisted of irinotecan administration at 7 hours after light onset and oxaliplatin delivery at 15 hours after light onset, i.e. when both drugs were given near their respective "best" circadian times. These would correspond to the middle of the night for irinotecan and the middle of the day for oxaliplatin in humans.

Abstract
PURPOSE Based on preclinical in vitro synergy data, this study evaluated the activity and toxicity of a gemcitabine/oxaliplatin combination in patients with metastatic and locally advanced pancreatic adenocarcinoma. PATIENTS AND METHODS Previously untreated metastatic and locally advanced unresectable pancreatic adenocarcinoma patients were enrolled onto this multicenter phase II study. Patients received gemcitabine 1,000 mg/m(2) as a 10-mg/m(2)/min infusion on day 1 and oxaliplatin 100 mg/m(2) as a 2-hour infusion on day 2 every 2 weeks. Patients with metastatic disease were treated until evidence of progressive disease, whereas patients with locally advanced disease received six cycles in the absence of progression, followed when appropriate by concomitant radiochemotherapy. RESULTS Among 64 eligible patients included in eight centers, 30 had locally advanced and 34 had metastatic disease. Response rate for the 62 patients with measurable disease was 30.6% (95% confidence interval, 19.7% to 42.3%), 31.0% for locally advanced and 30.3% for metastatic patients. Among 58 assessable patients, 40% had clinical benefit. Median progression-free survival and median overall survival (OS) were 5.3 and 9.2 months, respectively, with 36% of patients alive at 1 year. Median OS for patients with metastatic disease and locally advanced disease were 8.7 and 11.5 months, respectively. With 574 treatment cycles (median per patient, nine; range, zero to 27), grade 3/4 toxicity per patient was 11% for neutropenia and thrombocytopenia, 14% for nausea or vomiting, 6.2% for diarrhea, and 11% for peripheral neuropathy, with no toxic deaths. CONCLUSION Palliative effects, response rate, and survival observed with this well-tolerated gemcitabine/oxaliplatin combination deserve additional evaluation. A comparative study of combination therapy versus gemcitabine alone is ongoing.

Abstract
PURPOSE To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial. PATIENTS AND METHODS One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status less-than-or-equal 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 PM to 10:00 AM with peak at 4:00 AM). 5-FU dose was escalated from 900 to 1,100 mg/m(2)/d with fixed dose of l-FA at 150 mg/m(2)/d for 4 days every 14 days. RESULTS 5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years. CONCLUSION The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.

Abstract
BACKGROUND Patients with metastatic colorectal cancer are usually offered systemic chemotherapy as palliative treatment. A multivariate analysis was performed in order to identify predictors and their constellation that allow a valid prediction of the outcome in patients treated with 5-fluorouracil (5-FU)-based therapy. PATIENTS AND METHODS A total of 3825 patients treated with 5-FU within 19 prospective randomised and three phase II trials were separated into learning (n = 2549) and validation (n = 1276) samples. Data were analysed by tree analysis using the recursive partition and amalgamation method (RECPAM). A predictor could only enter the RECPAM analysis if the number of patients with missing values was < 33.3% within a node, and the minimal node size was set to 50 patients. Twenty-three potential predictors were grouped into subsets of laboratory variables (11 parameters), tumour-related variables (seven parameters) and clinical variables (five parameters). In the first step, tree analysis was performed separately for each predictor subset. The selected prognostic parameters of the resulting partial models (the 'winners') were entered into the general model. The classification rule from the data of the learning set was applied to the independent validation set. RESULTS Winners of the subgroup analysis for laboratory variables were: platelets > or = 400 x 10(9)/l, alkaline phosphatase > or = 300 U/l, white blood cell (WBC) count > or = 10 x 10(9)/l and haemoglobin < 11 x 10(9)/l, and all predicted a worse outcome. Negative predictors within the subgroup of tumour parameters were: number of tumour sites more than one or more than two, presence of liver metastases or peritoneal carcinomatosis, which predicted a worse outcome. Furthermore, presence of lung metastases, a primary rectal cancer and presence of lymph node metastases all predicted a better outcome in the multivariate setting. Among the clinical parameters only performance status of ECOG 0 or 1 predicted better outcome. In the final regression tree, three risk groups could be identified: low risk group (n = 1111) with a median survival of 15 months for patients with ECOG 0/1 and only one tumour site; intermediate risk group (n = 904) with a median survival of 10.7 months for patients with ECOG 0/1 and more than one tumour site and alkaline phosphatase < 300 U/l or patients with ECOG > 1, WBC count < 10 x 10(9)/l and only one tumour site; high risk group (n = 534) with a median survival of 6.1 months for patients with ECOG 0/1 and more than one tumour site and alkaline phosphatase of > or = 300 U/l or patients with ECOG > 1 and more than one tumour site or WBC count > 10 x 10(9)/l. The median survival times for the good, intermediate and high risk groups in the validation sample were 14.7, 10.5 and 6.4 months, respectively. CONCLUSIONS Patients can be divided into at least three risk groups depending on the four baseline clinical parameters: performance status, WBC count, alkaline phosphatase and number of metastatic sites. Any molecular or biological marker should be validated against these clinical parameters and decisions for more or less intensive treatments may be studied separately in these three risk groups. Also, clinical trials should be stratified according to the three risk groups.

Abstract
Colon cancer is a common cause of cancer-related mortality. Complete surgical resection of the primary tumor and/or select metastatic lesions can be curative in many patients. The risk of recurrence after resection can be predicted by pathologic staging. Large prospective randomized trials over the past 2 decades have clearly shown an increased overall survival for patients with resected stage III colon cancer who are treated with adjuvant 5-fluorouracil-based chemotherapy. The benefit of adjuvant chemotherapy for patients with stage II disease remains controversial. There is indirect evidence to support adjuvant chemotherapy after resection of metastatic disease. Locoregional approaches such as radiation, hepatic arterial infusion, or portal vein chemotherapy remain investigational. Adjuvant immunotherapy with monoclonal antibodies is emerging as a therapeutic option that might complement chemotherapy. Future challenges include improving adjuvant chemotherapy with the addition and/or substitution of new agents, resolving which subset of patients with stage II and resected stage IV colon cancer might benefit from therapy, validating the benefit of immunotherapy, and investigating locoregional therapies compared with systemic therapy.

Abstract
Adjuvant chemotherapy with fluorouracil and folinic acid improves overall survival for resected carcinoma of the colon of Dukes' stage C by 10-12%. In metastatic disease, response rates with fluorouracil-based regimens are about 25%. Combination with newer agents such as irinotecan and oxaliplatin can improve response rates to more than 50% in selected patients. New treatments with novel molecular targets will soon be entering clinical use. Despite these improvements, many patients undergo chemotherapy for resistant cancer, thus incurring side-effects without benefit. Expression of particular genes can be tested at the protein or RNA level and can be correlated with response or resistance to particular systemic therapies. Thus, predictive-factor testing of tumour biopsy samples may allow us to select chemotherapy or immunotherapy treatments with a high likelihood of benefit for the individual patient.

Abstract
The gold standard for clinical outcome of most cancers has been the clinical and pathologic staging of the tumors after surgery. For colorectal cancer (CRC), nodal involvement at the time the primary tumor is resected has been the most reliable indicator of clinical outcome; however, recently, combinations of molecular markers have been reported to be equivalent to pathologic or clinical staging in predicting clinical outcome. In addition, molecular markers can be used in conjunction with clinical or pathologic staging to provide a stronger indicator of clinical outcome than staging alone. We propose that "molecular staging" be added to pathologic staging to aid in predicting clinical outcome and making therapeutic decisions for colorectal cancers, especially stage II and III CRCs. We have reported that the clinical usefulness of most molecular markers varies with the ethnic group of the patients and the anatomic location of CRCs; this complicates the evaluation of prognostic biomarkers and requires much larger numbers of cases to be evaluated. Nevertheless, nuclear accumulation of p53 (p53(nac)) and phenotypic expression of Bcl-2, MUC-1 and p27(kip-1) may be molecular markers approaching acceptance for use in molecular staging of specific subgroups of colorectal cancers.

Abstract
Thymidylate Synthase (TS) is a rate-limiting enzyme in the DNA synthetic pathway and represents the cellular target of the antimetabolite drug 5-fluorouracil (FUra). Both preclinical and clinical studies have shown that the level of expression of this enzyme and the ability to achieve its inhibition are the major determinants of sensitivity and resistance to fluoropyrimidines (FP). In particular, five recent studies have consistently demonstrated an inverse correlation between the level of TS gene or protein expression measured in colorectal cancer metastases and the clinical response to either FUra or 5-fluorodeoxyuridine (FUdR). Patients with low levels of TS expression in their metastases have indeed shown response rates that are three to ten times higher compared to those obtained in patients with high TS levels. The independent predictive value demonstrated in a logistic regression model, the longer survival shown by patients with low TS levels in three of five studies and the consistency of the results obtained by independent groups using different techniques to quantitate TS expression, strengthen the predictive role of TS. Targeted treatment of colorectal cancer based on TS quantitation has thus been hypothesized similar to the use of hormone receptor in breast cancer. In this review preclinical and clinical data supporting the use of TS quantitation to predict for the clinical response to FUra will be described and unresolved problems including assays standardization, response prediction based on TS levels measured in primary tumors, intrapatient variations in TS levels and biological/biochemical limitations of this strategy will be discussed.

Abstract
PURPOSE This article reports the pharmacokinetics (PK) of heated intra-operative intraperitoneal oxaliplatin and its tolerance profile. Oxaliplatin has demonstrated significant activity in advanced colorectal cancer, and this is the first publication concerning its intraperitoneal administration. METHODS Twenty consecutive patients with peritoneal carcinomatosis (PC) of either gastrointestinal or uniquely peritoneal origin underwent complete cytoreductive surgery followed by intra-operative intraperitoneal chemo-hyperthermia (IPCH) with increasing doses of oxaliplatin. We performed IPCH using an open procedure (skin pulled upwards), at an intraperitoneal temperature of 42-44 degrees C, with 2 l/m2 of 5% dextrose instillate in a closed circuit. The flow-rate was 2 l/min for 30 min. Patients received intravenous leucovorin (20 mg/m2) and 5-fluorouracil (400 mg/m2) just before the IPCH to maximize the effect of oxaliplatin. We treated at least three patients at each of the six intraperitoneal oxaliplatin dose levels (from 260 to 460 mg/m2) before progressing to the next. We analysed intraperitoneal, plasma and tissue samples with atomic absorption spectrophotometry. RESULTS The mean duration of the entire procedure was 8.4 +/- 2.7 h. Half the oxaliplatin dose was absorbed in 30 min at all dose levels. Area under the curve (AUC) and maximal plasma concentration (Cmax) increased with dose. At the highest dose level (460 mg/m2), peritoneal oxaliplatin concentration was 25-fold that in plasma. AUCs following intraperitoneal administration were consistently inferior to historical control AUCs after intravenous oxaliplatin (130 mg/m2). Intratumoral oxaliplatin penetration was high, similar to absorption at the peritoneal surface and 17.8-fold higher than that in non-bathed tissues. Increasing instillate volume to 2.5 l/m2 instead of 2 l/m2 dramatically decreased oxaliplatin concentration and absorption. There were no deaths, nor severe haematological, renal or neurological toxicity, but we observed two fistulas and three deep abscesses. CONCLUSIONS Heated intraperitoneal chemotherapy gives high peritoneal and tumour oxaliplatin concentrations with limited systemic absorption. We recommend an oxaliplatin dose of 460 mg/m2 in 2 l/m2 of 5% dextrose for intraperitoneal chemo-hyperthermia, at a temperature of 42-44 degrees C over 30 min. We may be able to improve these results by increasing the intraperitoneal perfusion duration or by modifying the instillate composition.
