FEP regimen (epidoxorubicin, etoposide and cisplatin) in advanced gastric cancer, with or without low-dose GM-CSF: an Italian Trial in Medical Oncology (ITMO) study.

The new regimens developed over the last few years have led to an improvement in the treatment of advanced gastric cancer, and our previous experience confirmed the fact that the combination of etoposide, doxorubicin and cisplatin (EAP regimen) is an active treatment that leads to interesting complete remission rates. The primary end point of the present multicentre, randomized, parallel-group phase II study was to determine the activity of the simplified 2-day EAP schedule in patients with locally advanced or metastatic gastric cancer, and to verify whether the addition of low doses of granulocyte-macrophage colony-stimulating factor (GM-CSF) made it possible to increase dose intensity. Of the 62 enrolled patients, 30 were randomized to receive epirubicin 35 mg m(-2), etoposide 120 mg m(-2) and cisplatin 45 mg m(-2) (FEP) on days 1 and 2 every 28 days and 32 to receive the same schedule plus subcutaneous GM-CSF (molgramostin) 150 microg day(-1) on days 5-14 every 21 days.

Doxifluridine in colorectal cancer patients resistant to 5-fluorouracil (5-FU) containing regimens.

Doxifluridine (5-dFUR) is a fluoropyrimidine derivative, which is preferentially converted to 5-fluorouracil (5-FU) within tumour tissues. Although the activity of 5-FU in metastatic colorectal cancer is well recognised, resistance to this agent is frequently observed and remains its major limitation. The aim of this phase II study was to evaluate the activity of oral and i.

Randomized phase II noncomparative trial of oral and intravenous doxifluridine plus levo-leucovorin in untreated patients with advanced colorectal carcinoma.

Background: Doxifluridine (5-dFUR) is a fluoropyrimidine derivative that has been shown to be active on a variety of solid tumors. The clinical use of intravenous (i.v.

Phase II study of vinorelbine in patients with pretreated advanced ovarian cancer: activity in platinum-resistant disease.

Purpose: The aim of the study was to evaluate the activity of vinorelbine (VNLB) in a population of advanced ovarian cancer patients, with particular attention to defining its role in platinum-resistant disease.

Patients And Methods: Thirty-three patients were recruited and treated with VNLB 25 mg/m2 intravenously (IV) weekly. the median age was 53 years, performance status 0 to 2, and number of previous chemotherapy regimens two (range, one to five).

Clinical efficacy of octreotide in the treatment of metastatic neuroendocrine tumors. A study by the Italian Trials in Medical Oncology Group.

Background: The unsatisfactory control of neuroendocrine tumor growth with chemotherapy and/or interferon (IFN-2a) stimulated us to investigate the role of the somatostatin analogue octreotide (SMS 201.995), which is reported to be highly effective in controlling carcinoid syndrome symptoms. Octreotide has been used in a wide range of doses, and it was postulated that higher doses might lead to an objective response.

Doxifluridine as palliative treatment in advanced gastric and pancreatic cancer patients.

Background: The association of 5-fluorouracil (5-FU) and leucovorin is currently the most used combination in the treatment of advanced gastrointestinal neoplasms. Doxifluridine (d-FUR) is a fluoropyrimidine derivative that is converted into 5-FU inside tumor cells, where it is selectively cytotoxic. The oral administration of dFUR has been extensively investigated in colorectal carcinoma, and has been proven to be active and well tolerated.

Doxifluridine and leucovorin: an oral treatment combination in advanced colorectal cancer.

Purpose: This study was designed to test the activity and feasibility of an all-oral regimen of levo-leucovorin and doxifluridine (dFUR) in the treatment of advanced colorectal cancer and to establish whether the pharmacokinetics of dFUR and fluorouracil (FU) are affected by demographic and/or biologic parameters.

Materials And Methods: One hundred eight patients with histologically proven colorectal cancer received orally administered levo-leucovorin 25 mg followed 2 hours later by dFUR 1,200 mg/m2 on days 1 to 5, with the cycle being repeated every 10 days.

Results: Among 62 previously untreated patients, two complete responses (CRs) and 18 partial responses (PRs) were observed (overall response rate, 32%; 95% confidence interval, 21% to 45%).

Endocrinological and clinical evaluation of exemestane, a new steroidal aromatase inhibitor.

The androstenedione derivative, exemestane (FCE 24304), is a new orally active irreversible aromatase inhibitor. Fifty-six post-menopausal advanced breast cancer patients entered this study to evaluate the activity of four low exemestane doses in reducing oestrogen levels. The drug's tolerability and clinical efficacy were also assessed.

Combination goserelin and tamoxifen therapy in premenopausal advanced breast cancer: a multicentre study by the ITMO group. Italian Trials in Medical Oncology.

It has been suggested that tamoxifen may improve the efficacy of medical castration with luteinising hormone-releasing hormone analogues, but very few data have so far been published concerning the clinical and endocrinological activity of this therapeutic modality. In this phase II multicentre trial conducted by the Italian Trials in Medical Oncology group (ITMO), 64 premenopausal patients with hormone receptor-positive or unknown breast cancer were treated with monthly s.c.

Doxifluridine: an active agent in advanced gastrointestinal cancer.

Background: The results of the use of chemotherapy in patients with advanced gastrointestinal malignancies have been disappointing. Complete responses are rare, and even partial responses are generally few with no benefit on survival. Since its introduction in clinical trials more than 30 years ago, fluorouracil has remained the most effective single agent in the treatment of these diseases.

Feasibility of intraportal chemotherapy with fluorouracil and folinic acid immediately after hepatic resection for colorectal metastases.

Background: About 50% of recurrence after resection of hepatic metastases from colorectal cancer remain confined to the liver. Adjuvant locoregional treatments could reduce the failure rate, but these treatments have been scantily investigated. Experimental models have shown that both intra-arterial chemotherapy (IAC) and intraportal chemotherapy (IPC) in adjuvant setting were able to reduce metastatic growth, but IPC should be initiated in the immediate postoperative period.

Phase II study of the etoposide, leucovorin and fluorouracil combination for patients with advanced gastric cancer unsuitable for aggressive chemotherapy.

Many patients with advanced gastric cancer cannot be treated with intensive chemotherapy. In an attempt to provide a feasible regimen for such patients, the combination of etoposide, leucovorin and fluorouracil (ELF) has been developed with promising results. The present study involved 42 patients with advanced gastric cancer who where unsuitable for cisplatin- or anthracycline-containing regimens because of their age (24 patients over 65 years), poor performance status (12) or the presence of concomitant illness (6).

A phase II trial of dacarbazine, fluorouracil and epirubicin in patients with neuroendocrine tumours. A study by the Italian Trials in Medical Oncology (I.T.M.O.) Group.

Background: Previous experiences in the treatment of neuroendocrine tumours have demonstrated some activity of single agents such as adriamycin, fluorouracil (FU), streptozotocin and dacarbazine (DTIC). Opinions concerning the usefulness of polychemotherapy in carcinoid tumours are discordant, whereas better results have been achieved in other endocrine pancreatic neoplasms. Based on this background, we used multidrug chemotherapy with DTIC, FU and epirubicin in the treatment of different neuroendocrine tumours.

Control of emesis by a low dose of ondansetron and dexamethasone.

Aims And Background: Ondansetron, a selective serotonin type 3 receptor antagonist, has been investigated at a wide range of doses. Recent studies have demonstrated that a single dose of this drug is active, either by intravenous bolus or continuous infusion. The main aim of this study was to evaluate the efficacy of a low dose of ondansetron in a simple and feasible schedule as follows: ondansetron 8 mg i.

Combined liver and pancreatic islets transplantation in man using cyclosporin immunosuppression.

We report a 1-year patient and graft survival after combined liver-pancreatic islet transplantation. The patient was affected by a pancreatic neuroendocrine carcinoma with extensive liver metastasis. Native pancreas and total liver removal was undertaken after a good response to chemotherapy, and the patient was still cancer-free 1 year later.

Etoposide, doxorubicin and cisplatin (EAP) treatment in advanced gastric carcinoma: a multicentre study of the Italian Trials in Medical Oncology (I.T.M.O.) Group.

Various reports have documented the efficacy of the combination of etoposide, doxorubicin and cisplatin (EAP) in the treatment of advanced gastric cancer, although other studies have not confirmed such results. This multicentre phase II study was designed to try to define the efficacy and tolerability of the original EAP regimen. From January 1990 to May 1992, 96 patients with locally advanced or metastatic gastric cancer were treated every 3 weeks with etoposide (120 mg/m2) on days 4, 5 and 6, doxorubicin (20 mg/m2) on days 1 and 7, and cisplatin (40 mg/m2) on days 2 and 8.

Medical treatment of neuroendocrine tumors.

Background: Tumors of the neuroendocrine system are characterized by amine precursor uptake and decarboxylation, and they represent a heterogeneous group of carcinomas including carcinoids, islet cell carcinomas of the pancreas, medullary thyroid carcinomas and Merkel cell carcinomas. Their similar cytochemical and ultrastructural properties sustain the hypothesis of a common embryologic origin within the neural crest. Many of these tumors grow slowly, and reducing tumor burden represents the treatment of choice.

Treatment of metastatic carcinoids and other neuroendocrine tumors with recombinant interferon-alpha-2a. A study by the Italian Trials in Medical Oncology Group.

Background: Using a wide range of interferon (IFN) doses and schedules, a number of authors have found them to be active against neuroendocrine tumors.

Methods: To verify the clinical activity of IFN, 49 evaluable patients with advanced stage low- and intermediate-grade neuroendocrine tumors were treated with recombinant IFN-alpha-2a at a daily dose of 6 x 10(6) IU intramuscularly for 8 weeks, and 3 times weekly thereafter. The predominant histotype was carcinoid, although a few cases had malignant islet cell tumors, medullary thyroid carcinoma, Merkel cell carcinoma, or other neuroendocrine tumors.

Salvage treatment after r-interferon alpha-2a in advanced neuroendocrine tumors.

The use of inteferon (IFN) in neuroendocrine advanced tumors has achieved control of hormonal symptoms but low objective tumor response rate. In patients resistant to, or failing on, IFN a second line treatment may be required. Seventeen patients having received recombinant IFN alpha-2a as last treatment entered the study.

Treatment of carcinoid syndrome with recombinant interferon alpha-2a.

The prognosis and the quality of life of patients with carcinoid tumors is related either to symptoms from the substances secreted or to progressive tumor growth. Medical treatment with cytotoxic agents is of marginal value for increasing life expectancy and reducing clinical symptoms. Recent studies with interferon have shown interesting results.

Adjuvant chemotherapy for cancer of gastrointestinal tract: a critical review.

Surgery is the only curative therapeutic approach for gastrointestinal tumors. If the tumor is deeply infiltrating through serosa or invading regional lymph nodes, the 5-year patient's survival is about 60% and < 40%, respectively. The natural history and prognosis of neoplasms from colon, rectum and stomach are different.
