Background: We have previously shown that an intensified preoperative regimen including oxaliplatin plus raltitrexed and 5-fluorouracil/folinic acid (OXATOM/FUFA) during preoperative pelvic radiotherapy produced promising results in locally advanced rectal cancer (LARC). Preclinical evidence suggests that the scheduling of bevacizumab may be crucial to optimize its combination with chemo-radiotherapy.
Patients And Methods: This non-randomized, non-comparative, phase II study was conducted in MRI-defined high-risk LARC.
Background: We have extensively assessed a biweekly regimen of irinotecan plus folinic acid and fluorouracil bolus (IRIFAFU) in metastatic colorectal cancer (MCRC). Here, we report on the safety and activity of BIFF (bevacizumab plus IRIFAFU) regimen in 94 mCRC patients.
Patients And Methods: Bevacizumab 5 mg/kg (1 hour), and irinotecan 180 mg/m(2) (1 hour) were given intravenously on day 1, 6S-folinic acid 250 mg/m(2) (2 hours), and fluorouracil 850 mg/m(2) (bolus) were given intravenously on day 2 every 2 weeks for a median of 9 cycles per patient (range, 1-12), and maintenance bevacizumab alone was delivered in 16 cases.
A cohort of 206 consecutively-collected patients with colorectal carcinoma (CRC) were screened for germline mutations in the principal DNA mismatch repair (MMR) genes, MLH1 and MSH2, and in the Fanconi anemia (FA) genes involved in homologous recombination DNA repair. Mutation analysis was performed by denaturing high-performance liquid chromatography (DHPLC) and automated sequencing. Available paraffin-embedded tumor tissues were evaluated for gene expression by immunohistochemistry.

Methods And Materials: Sixty-three patients with the following characteristics, a clinical (c) stage T4, cN1-2, or cT3N0 of ≤5 cm from the anal verge and/or with a circumferential resection margin (CRM) of ≤5 mm (by magnetic resonance imaging), received three biweekly courses of chemotherapy with OXA, 100 mg/m2; raltitrexed (RTX), 2.5 mg/m2 on day 1, and 5-fluorouracil (5-FU), 900 mg/m2 (31 patients) or 800 mg/m2 (32 patients); levo-folinic acid (LFA), 250 mg/m2 on day 2, during pelvic RT (45 Gy).
Background: No differences in response rate (RR), progression-free survival (PFS), overall survival (OS) and quality of life (QoL) were seen in patients randomly treated with biweekly oxaliplatin plus either fluorouracil/folinic acid or capecitabine.
Methods: We investigated the independent effect of baseline clinical characteristics and physical functioning (PF) domain on RR, PFS, and OS in 310 patients who completed the EORTC QLQ-C30 questionnaire. Multivariate analyses stratified by treatment were performed.
The prognosis of patients with metastatic colorectal cancer has significantly improved in the last few years, with the introduction into the clinical practice of new cytotoxic treatments, the availability of non-cross resistant agents after the front-line treatment failure, and the combination of targeted agents (i.e., the inhibitors of the epidermal growth factor and vascular endothelial growth factor pathways) with conventional drugs.

Patients And Methods: Patients in stage IIIB or IV NSCLC were randomly allocated to receive either gemcitabine 1250 mg/m(2) on day 1, and pemetrexed (Alimta) 500 mg/m(2) followed by gemcitabine 1250 mg/m(2) on day 8 of a 3-weekly cycle (GA arm), or paclitaxel 120 mg/m(2) followed by gemcitabine 1000 mg/m(2), both given on days 1 and 8 of a 3-weekly cycle (PG arm).
Results: 105 (GA arm, 51; PG arm, 54) eligible patients (stage IV, 32 and 30, respectively) were enrolled into this study; thereafter, accrual was stopped due to first-stage analysis.
Oxaliplatin is a third-generation platinum compound that has shown a definite role in the management of colorectal cancer (CRC). Oxaliplatin in combination with fluorouracil and leucovorin in the FOLFOX4 regimen represents a new standard of treatment in the adjuvant setting as well as for the metastatic disease. The combination of oxaliplatin with capecitabine in the XELOX regimen has been demonstrated to be not inferior to FOLFOX4 in metastatic patients, and it is under evaluation, with or without bevacizumab, in the post-surgical management of resected patients.

More recently, triplet regimens that incorporate fluorouracil and cisplatin with epirubicin (ECF) or docetaxel are being used in the management of patients with metastatic disease; ECF is also being used as preoperative treatment of resectable disease. Capecitabine, a prodrug of fluorouracil that can be taken orally, has been assessed as an alternative to intravenous fluorouracil and has demonstrated noninferiority to its parent compound.
View Article and Find Full Text PDFPurpose: This phase II trial assessed the tolerability and efficacy of a triplet of oxaliplatin, irinotecan, and fluorouracil/folinic acid in advanced gastric cancer.
Methods: Patients with unresectable or metastatic gastric cancer, unexposed to palliative chemotherapy, received oxaliplatin 85 mg/m(2) iv and irinotecan 150 mg/m(2) iv on day 1, 6S-folinic acid 250 mg/m(2) iv and fluorouracil 750 mg/m(2) iv on day 2, every 2 weeks. Response rate (RR) was assessed after a minimum of four cycles, and treatment continued up to 12 cycles.
Purpose: Oxaliplatin combined with either fluorouracil/leucovorin (OXAFAFU) or capecitabine (OXXEL) has a demonstrated activity in metastatic colorectal cancer patients. We aimed at comparing these two regimens in terms of response rate (RR), safety, progression-free survival (PFS), and quality of life (QoL) of patients.
Methods: A total of 322 patients with metastatic colorectal cancer were randomized to receive biweekly: oxaliplatin 100 mg/m(2) i.

5-fluorouracil/leucovorin, with or without oxaliplatin or irinotecan, is the most widely used treatment for the metastatic as well for the adjuvant setting of colorectal cancer. These agents are administered intravenously (by bolus or infusion), thereby causing significant inconvenience to patients. Capecitabine, an oral fluoropyrimidine, has been demonstrated to be at least as effective as bolus 5-fluorouracil/leucovorin in terms of time to disease progression, time to treatment failure, and overall survival, but achieves significantly higher response rates and has the advantage of oral administration.

Moreover, capecitabine has demonstrated a better tolerability profile, producing a significantly lower occurrence of severe stomatitis than 5FU plus folinic acid regimens, making this drug particularly attractive for treating elderly patients. In addition, capecitabine can be combined with other active drugs such as irinotecan or oxaliplatin.

5-Fluorouracil, usually in combination with folinic acid, is widely used in the treatment of both colorectal and head and neck squamous cell cancer patients. Since 5-fluorouracil plus folinic acid and the antifolate thymidylate synthase inhibitor; raltitrexed have distinct mechanisms of action and toxicity profiles, we have evaluated the potential synergistic antitumor interaction between these two agents combined with a sequential schedule of administration in KB (wt-p53) and Cal27 (mut-p53) head and neck squamous cell carcinomas, and LoVo (wt-p53) and HT29 (mut-p53) colorectal cell lines. The combination between a 24-h exposure to raltitrexed followed by a 4-h exposure to 5-fluorouracil plus folinic acid was globally synergistic, as assessed by the median effect principle and combination index.

Oxaliplatin (OXA) and irinotecan (IRI) are active drugs for metastatic colorectal cancer, their toxicity profiles are not overlapping, and both drugs have shown at least additivity with folinic acid-modulated 5-fluorouracil (5FU). We carried out this phase II study to assess the activity and toxicity of a biweekly regimen including OXA plus IRI on day 1, and levo-folinic acid (LFA) plus 5FU on day 2 (OXIRIFAFU) in pretreated patients with metastatic colorectal cancer. Forty-one patients, all previously treated with adjuvant and/or palliative 5FU-based chemotherapy (16 of them already exposed to IRI, OXA or both), were enrolled into this trial.

Patients And Methods: Advanced BC patients pretreated with anthracycline- and paclitaxel-based chemotherapy were eligible. DTX (80 mg/m2) and CPT-11 (100 mg/m2) were given biweekly with filgrastim support (300 microg/day on days 4-7).
Purpose: The present study was aimed at defining the antitumor activity of the cisplatin-epirubicin-paclitaxel (PET) weekly administration with granulocyte colony-stimulating factor (G-CSF) support in chemonaive small-cell lung cancer patients with extensive disease (ED-SCLC).
Methods: Chemonaive ED-SCLC patients received cisplatin 30 mg/sqm, epirubicin 50 mg/sqm and paclitaxel 120 mg/sqm, weekly, with G-CSF (5 microg/kg from day 3 to 5) support, for a maximum of 12 weeks.
Results: Thirty-nine patients were treated, for a total of 354 cycles delivered.
Background: In patients with metastatic colorectal carcinoma (MCC), capecitabine has demonstrated a superior response rate (RR), equivalent disease progression-free (PFS) and overall survival (OS), and an improved overall tolerability profile compared with bolus 5-fluorouracil/leucovorin (5-FU/LV). The FOLFOX4 regimen, combining oxaliplatin with LV and bolus plus infusional 5-FU (LV5FU2), has been shown to improve RR and PFS versus LV5FU2, and it was more effective and less toxic than irinotecan plus bolus 5-FU/LV. Capecitabine (an oral fluoropyrimidine) may be an effective, well tolerated, and more convenient alternative to 5-FU/LV in combination with oxaliplatin, especially in older patients.
