Abstract
Drug stability and compatibility are critical factors influencing the cost and logistics of treatment delivery, therapeutic effectiveness, and patient safety. This is particularly significant in the realm of cancer chemotherapeutics, where stability and compatibility studies play a vital role in ensuring rational and safe medicine administration. Oxaliplatin, fluorouracil, and irinotecan, commonly used in various combinations for gastrointestinal cancers, are complemented by co-administration of folinic acid in certain protocols. Notably, some folinic acid preparations include trometamol as an excipient, potentially impacting the stability of the chemotherapeutic agents if infused concomitantly. This study seeks to establish guidelines for oncology multidisciplinary teams, addressing potential risks associated with the combination of trometamol-containing folinic acid and chemotherapeutics. To achieve this, a quantitative questionnaire was distributed to members of the British Oncology Pharmacy Association (BOPA) and non-BOPA members through an online survey. Nineteen healthcare professionals with oncology experience, comprising 18 pharmacists and one nurse, completed the questionnaires. Each participant rated the validity and clarity of statements on a 5-point scale. The Delphi process concluded after the fourth round, consolidating the findings and recommendations from the multidisciplinary team. Twelve recommendations for safe practice have been made.

Abstract
Background The first one-arm phase II trial aimed to evaluate and predict efficacy and safety of S-1 plus oral leucovorin (S-1/LV) as first-line chemotherapy for patients with advanced gastric cancer (AGC), using S-1 pharmacogenetic pathway approach. Patients and methods A total of 39 patients orally took S-1 at conventional dose and LV simultaneously at a dose of 25 mg twice daily for a week, within a 2-week cycle. The primary endpoint was overall response rate (ORR), while the secondary endpoints were progression-free survival (PFS), time to failure (TTF), overall survival (OS), disease control rate (DCR), and adverse events (AEs). Peripheral blood was sampled prospectively for baseline expression of dihydropyrimidine dehydrogenase (DPD), orotate phosphoribosyltransferase (OPRT), thymidine phosphorylase (TP), and thymidylate synthase (TS), CYP2A6 gene polymorphisms, and 5-FU pharmacokinetics. Results The ORR and DCR were 41.0 and 76.9%. The median PFS, TTF, and OS were 4.13, 3.70, and 11.40 months. Grade 3–4 AEs occurred in only 13 patients, and grade 4 AEs occurred in only 1 of them. High OPRT/TS and peritoneal metastasis (vs. liver metastasis) independently predicted responding. High OPRT/DPD independently predicted grade 3–4 AEs. High AUC0–24h of 5-FU and metastatic/recurrent sites ≤2 (vs. >3) independently predicted prolonged PFS. Low baseline plasmic DPD independently predicted prolonged OS. Conclusions Two-week, oral S-1/LV regimen demonstrated promising efficacy and safety as first-line chemotherapy for AGC.

Abstract
BACKGROUNDS The prognostic value of biomarkers in metastatic colorectal cancer (mCRC) patients with liver metastases remains unclear. We assessed the difference of expression of biomarkers between primary tumors and liver metastases treated with chemotherapy in mCRC patients, as well as the prognostic value of these markers. METHODS Forty-three mCRC patients with liver-limited disease from January 2007-November 2011 were analyzed. They all received resection of primary tumors followed by oxaliplatin-based chemotherapy. After chemotherapy, they all received hepatic resection. Forty-three paired primary and metastatic tumor specimens were collected to measure the messenger RNA expression of six biomarkers by the Danenberg tumor profile method (thymidylate synthase, dihydropyrimidine dehydrogenase [DPD], excision repair cross-complementing gene1, thymidine phosphorylase [TP], folylpolyglutamate synthase, and regenerating islet-derived family, member 4). RESULTS Thirty-six patients' messenger RNA was used for analysis. All markers showed similar expression between primary and metastatic sites. The low-expression group of Danenberg tumor profile and TP in the primary tumor showed significantly higher overall survival than the high-expression group (P < 0.001 and P = 0.033), but for DPD and TP in liver metastases, there were no significant differences of overall survival between the two groups. The ratios of marker expression in liver metastatic site to that in primary site of DPD and TP were significantly higher in chemo-responders than in non-chemo-responders (P = 0.034 and P = 0.022). CONCLUSIONS Biomarkers' expressions in liver metastases were similar to those in the primary tumor. DPD and TP in the primary lesion may be a prognostic factor in chemotherapy-naïve mCRC patients with liver-limited disease, but those in liver tumor were not. Further validated analysis to our results would be warranted.

Abstract
This study was designed to explore the possible interaction of 5-fluorouracil (5-FU) and 7-ethyl-10-hydroxycamptothecin (SN-38) in vitro. Human colon cancer LoVo cells were treated in both a dose- and time-dependent manner using clinically relevant concentrations of and exposure to 5-FU and/or SN-38. The expression of thymidylate synthase (TS), topoisomerase I, and cell cycle kinetics were evaluated by Western blot analysis and flow cytometry, respectively. Cytotoxicity was evaluated by MTT (3-[4,5-dimethylthiazol-2yl]-2,5-diphenyl tetrazolium bromide) assay. The cytotoxic effects of combination treatment were determined by median effect analysis. Topoisomerase I expression was downregulated following 12 hours of exposure to treatment, and topoisomerase I expression recovered 8 hours after SN-38 was removed. The TS expression was decreased following 24 hours of 5-FU and it remained at reduced levels for > 24 hours after removal of 5-FU. SN-38 induced an arrest at S/G2/M phase, reaching its maximum effect at 12 hours. This cell cycle arrest was reversed 24 hours after SN-38 was removed. 5-FU induced an arrest at the S phase, and maximum arrest occurred at 12 hours and lasted for > 48 hours. After 12 hours of sequential SN-38, LoVo cells were arrested in S phase, thereby potentiating the effect of 5-FU. Cytotoxicity studies confirmed the synergistic interaction between 5-FU and irinotecan. These findings suggest that the proper sequencing of 5-FU/irinotecan depends on regulation of topoisomerase I, and cell cycle kinetics

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
BACKGROUND Folates, components of the B-complex vitamins, have numerous pharmacological effects. In oncology combining folates with 5-fluorouracil (5-FU) enhances the cytotoxic effects of chemotherapy in colon cancer patients. Folic acid has been rarely involved in adverse allergic reactions. To the best of our knowledge no anaphylactic reaction secondary to folinic acid (FA) administration has ever been reported before. PATIENTS AND METHODS An 80-year-old patient had adjuvant chemotherapy for colon cancer including FA and 5-FU and irinotecan as a second line agent after multiple metastases. RESULTS Following FA administration anaphylactic shock occurred. Diagnosis was made according to the French method of adverse reactions monitoring. CONCLUSION Anaphylactic shock may be an adverse reaction of FA in patients receiving chemotherapy for colon cancer.

Abstract
The fluorinated pyrimidines have played a major role in the treatment of many common tumors since 5-fluorouracil (5FU) was first introduced. Studies of the cellular and clinical pharmacology of 5FU have led to an improved understanding of the mechanisms of action of this agent. This knowledge has allowed the optimal and rational development of fluoropyrimidine therapy, with significant therapeutic advances in recent years. Efforts to improve the therapeutic index of 5FU have included alteration of schedule, and the addition of biochemical modulators such as folinic acid. Although protracted continuous infusion of 5FU has led to better response rates and decreased toxicity, the administration of 5FU by protracted infusion is not only costly, but also inconvenient to the patient. Furthermore it is often associated with infectious and thrombotic complications related to the required indwelling intravenous catheter. Protracted oral administration is a rational route for administering 5FU, being preferred by the patient and the pharmaco-economist. The unpredictable and low oral bioavailability of 5FU initially discouraged this form of treatment. This problem has now been overcome by the new generation of oral fluoropyrimidines. Two main strategies have been pursued: 1) The administration of an inactive prodrug of 5FU, which is absorbed intact, and subsequently converted to 5FU. Capecitabine is converted to 5FU by a 3 step enzymatic process. 2) The administration of 5FU with an inhibitor of dihydropyrimidine dehydrogenase (DPD) to minimise the erratic absorption and variable clearance of 5FU: the preparations UFT, S1, and ethinyluracil/5FU contain an oral fluoropyrimidine co-administered orally with inhibitors of this enzyme. The development and characteristics of these agents are discussed.

Abstract
The aim of the study was to evaluate the efficacy, tolerability and quality of life in 5-fluorouracil (5-FU) pretreated colorectal cancer patients after combined 5-FU and Ginkgo biloba extract GBE 761 ONC (i.e. the Ginkgo biloba special extract EGb 761(R)) therapy. Following conventional 5-FU therapy, 44 patients (32 evaluable for response) with advanced progressive colorectal cancer were treated every 3 weeks with courses of 350 mg GBE 761 ONC as a 30 min i.v. infusion on days 1-6 followed by 500 mg/m(2)/d 5-FU as a 30 min i.v. infusion on days 2-6. The response to therapy was evaluated after the second and fourth course of treatment. The data of 32 patients could be evaluated for efficacy. We observed a progression of disease in 22 patients, no change in 8 patients and a partial response in 2 patients (overall response = 6.3%). Seventeen of 22 patients with observed progressive disease showed further progression after two cycles, two after three cycles and three after four cycles. The median survival time was 9.5 months (7.7-11.5 months). GBE 761 ONC was well tolerated. Adverse events that occurred during the study were mainly myelosuppression and gastrointestinal symptoms and were judged to be 5-FU related or consistent with liver toxicity and thus tumour related. Our results suggest a good benefit-risk ratio of the combined 5-FU and GBE 761 ONC therapy as second line treatment in metastatic colorectal cancer. The survival time was similar to that known from second line treatment according to the Ardalan scheme. Since an improvement was observed in some patients despite the failure of the conventional 5-FU pretreatment, it would be interesting to evaluate whether the application of 5-FU plus GBE 761 ONC as a first line treatment is of benefit.

Abstract
Despite the perception that standard 5-fluorouracil/folinic acid (5-FU/FA) (425 mg/m2 per day and 20 mg/m2 per day intravenously once daily x 5 every 4 or 5 weeks) is well tolerated, we have been impressed by toxicity seen and frequent need for dose modification. We performed a retrospective analysis to quantitate the proportion of patients experiencing toxicity and attempted to identify associated clinical characteristics. One hundred thirty-four patients received 5-FU/FA at standard doses described by the Mayo regimen. Patient characteristics were as follows: female 35%, median age 66 years, Eastern Cooperative Oncology Group performance status less than or equal to 2, 96%. Sixty-eight percent received chemotherapy for metastatic disease. Forty-seven patients (35%+/-8%) experienced significant toxicity and were unable to receive the second cycle as scheduled: 76% required dose reduction, 11% discontinued therapy (including two toxic deaths), 11% discontinued therapy during the first cycle, and 2% required dose delay. Logistic regression was used to explore the following as predictors of toxicity: age, sex, performance status, adjuvant versus metastatic setting, prior chemotherapy, prior radiation, mean corpuscular volume, red blood cell distribution width, albumin, alkaline phosphatase, aspartate aminotransferase, bilirubin, and calculated creatinine clearance. No clinical characteristic was found to predict toxicity. Only high bilirubin approached statistical significance. We conclude that standard 5-FU/FA, when used in the general population, is associated with significant toxicity. Known clinical characteristics are not helpful in predicting toxicity. The lack of previous formal phase I evaluation of this regimen of 5-FU/FA raises concerns regarding its safety and generalizability in clinical practice.

Abstract
The use of bolus 5-fluorouracil (5-FU) as a short-term infusion over 10-30 min is increasing at the cost of a push injection, mainly due to practical advantages. Since even a short prolongation of the administration time results in lower 5-FU peak and area under the curve (AUC) levels, there might be a risk of decreased efficacy. The aim of this study was to compare a rapid intravenous (i.v.) 5-FU injection and a short-term 5-FU infusion with respect to objective responses and toxicity in patients with advanced colorectal cancer. 203 patients with measurable advanced colorectal cancer were randomised to bolus 5-FU either as an injection for 2-4 min or as a short-term infusion lasting 10-20 min. In both groups, the 5-FU dose was 500 mg/m2 and leucovorin 60 mg/m2 was given 40 min after the start of 5-FU. Treatment was given on two successive days every other week until progression. Objective tumour regression was seen in 27/100 (27%) in the injection group and in 13/103 (13%) in the infusion group (P = 0.02). Severe toxicity was rare and did not differ significantly between the groups. Progression-free survival tended to be longer in the injection group (P = 0.07), but overall survival did not differ between the groups. Bolus 5-FU should be administered as a rapid i.v. injection rather than as a short-term infusion, since the former rate of administration results in a higher response rate without being significantly more toxic.

Abstract
Aims and background There is evidence that fluorouracil (FU), when administered by protracted venous infusion, has antitumor activity in pretreated breast cancer. The aims of the study were to assess, in a population of heavily pretreated breast cancer patients (≥2 lines of chemotherapy previously administered), the feasibility and activity of a new combination of oral L-leucovorin and continuous FU infusion. Methods Patients were treated with the following combination: oral L-leucovorin, 5 mg/m2 days 1 through 14, plus FU, 250 mg/m2 days 1 through 14, with cycles repeated every 21 days. Results Since November 1994, 22 patients have entered the study and 20 are assessable for response and side effects. Major patient characteristics were: ECOG performance status, 0-2; median age, 56 years (range, 41–70); sites of metastasis, bone 9, lung 8, liver 2, pleura 7; 2 or more metastatic sites, 18. A total of 74 cycles has been administered (median/patient, 3 cycles). Five partial remissions (25%), 4 disease stabilizations and 11 disease progressions have been observed. Median time to progression was 3 months (range 1–6+). Grade I–II mucositis was observed in 8 patients and grade III–IV in 6 patients. Other side effects have included diarrhea and thrombocytopenia. Conclusions The schedule has demonstrated moderate activity in heavily pretreated breast cancer, with mucositis as the dose-limiting toxicity.

Abstract
BACKGROUND Although leucovorin (LV) + 5-fluorouracil (5-FU) is considered the treatment of choice for advanced colorectal cancer in most countries, the optimal schedule of this combination has not yet been established. Low-dose LV appears to be as active as high-dose LV in the daily-times-five regimen, but no randomized study of the levorotatory stereoisomer (6S-LV) given at two different dose levels has been published. PATIENTS AND METHODS Between November 1991 and June 1994, 422 patients (all with measurable disease previously untreated with chemotherapy) were randomized to 6S-LV (100 mg/sqm/i.v.) + 5-FU (370 mg sqm/15 min i.v. infusion), both administered for 5 days every 28 days (arm A), or to 6S-LV (10 mg/sqm/i.v./5-FU (doses as above), also given for 5 days every 28 days (arm B). The primary endpoint of the study was the comparison of response rates (WHO criteria): the secondary endpoint was the assessment of survival and tolerability. No evaluation of the quality of life or the symptomatic effect of treatment was planned. RESULTS The response rate was 9.3% in arm A (95% CI: 5.4-13.1), with 2 CR and 18 PR, and 10.7% in arm B (95% CI: 6.5-14.9), with 3 CR + 19 PR, without any significant difference (P = 0.78). The median time to progression was eight months in both groups and overall survival was 11 months, with no difference between treatments. Toxicity mainly consisted of gastrointestinal side effects (mucositis and diarrhoea), which were rarely severe (grade 3-4: 5%-10% of patients) and similar in the two groups. CONCLUSIONS In this large-scale multicentre trial, the low and high doses of 6S-LV appeared to be equivalent in terms of the biochemical modulation of 5-FU in advanced colorectal cancer although, for several reasons (including the timing and the strict criteria of response evaluation, the high number of patients with unfavourable prognostic factors, the multi-institutional nature of the study, the dose and modality of 5-FU administration), the response rate was lower than that reported in some of the other published studies. Given the considerable difference in economic cost between the two dosages, the use of high-dose 6S-LV in the daily-times-five regimen is not recommended in clinical practice.
