Tamoxifen vs Tamoxifen plus 13-cis-retinoic acid vs Tamoxifen plus Interferon alpha-2a as first-line endocrine treatments in advanced breast cancer: updated results of a phase II, prospective, randomised multicentre trial.

Aims And Background: To demonstrate the efficacy of 13-cis-retinoic acid (RA) or Interferon alpha-2a (IFN alpha-2a) with Tamoxifen (TAM) in the treatment of advanced breast cancer.

Methods: Ninety-nine postmenopausal patients with advanced breast cancer, and a positive or unknown estrogen (ER) or progesterone (PgR) receptor status, were randomised to receive TAM 20 mg/m2/day orally (arm A), or TAM plus RA 1 mg/kg/day orally (arm B), or TAM plus IFN alpha-2a 3 MU thrice a week intramuscular (arm C). The three treatment groups were well balanced in terms of the main prognostic factors.

Survival and safety of exemestane versus tamoxifen after 2-3 years' tamoxifen treatment (Intergroup Exemestane Study): a randomised controlled trial.

Background: Early improvements in disease-free survival have been noted when an aromatase inhibitor is given either instead of or sequentially after tamoxifen in postmenopausal women with oestrogen-receptor-positive early breast cancer. However, little information exists on the long-term effects of aromatase inhibitors after treatment, and whether these early improvements lead to real gains in survival.

Methods: 4724 postmenopausal patients with unilateral invasive, oestrogen-receptor-positive or oestrogen-receptor-unknown breast cancer who were disease-free on 2-3 years of tamoxifen, were randomly assigned to switch to exemestane (n=2352) or to continue tamoxifen (n=2372) for the remainder of a 5-year endocrine treatment period.

Evaluation of HER-2/neu amplification and other biological markers as predictors of response to neoadjuvant anthracycline-based chemotherapy in primary breast cancer: the role of anthracycline dose intensity.

Objectives: The value of HER-2/neu status as a predictor of response to anthracycline-based chemotherapy is still a matter of debate. We evaluated the contribution of HER-2/neu gene amplification and other biologic markers in predicting response to different doses of neoadjuvant anthracycline-based chemotherapy.

Methods: Clinical and pathologic records of 115 primary breast cancer patients were reviewed.

Attitudes to, and practice of, unconventional medicine by physicians in Italy.

Background: Given the great public demand for unconventional medicines (UM) in most Western countries, the aim of this study was to assess the attitudes to, and supply of, UM by physicians in Italy.

Methods: A cross-sectional survey of all of the physicians belonging to the Ordine dei Medici of the province of Parma was carried out by means of an anonymous questionnaire mailed to 2631 physicians and returned by 1734 (66%). The outcome measurements were the prevalence of opinions concerning UM, the prevalence of its practice, and the extent to which demographic and practice characteristics influenced it.

Primary chemotherapy in operable breast carcinoma comparing CMF (cyclophosphamide, methotrexate, 5-fluorouracil) with an anthracycline-containing regimen: short-term responses translated into long-term outcomes.

Background: The role of anthracyclines has been extensively studied in adjuvant chemotherapy, but much less in the primary chemotherapy of early breast carcinoma. This study, comparing CMF (cyclophosphamide, methotrexate, 5-fluorouracil) with the rotational anthracycline-containing regimen CMFEV (CMF plus epirubicin and vincristine) administered as primary chemotherapy, demonstrated a significant increase in clinical complete response in premenopausal women. We report the long-term results.

Hepatic artery administration of docetaxel in liver metastases from breast carcinoma: a feasibility study.

Aims And Background: Taxanes are largely metabolized and almost exclusively excreted in the feces by the liver through the biliary pathway, thus providing a rationale for investigating the activity of their hepatic artery delivery in case of liver metastases.

Study Design: The aim of this study was to assess the feasibility of administering docetaxel via the hepatic artery in advanced breast cancer patients in whom the liver was the only or the predominant site of metastatic involvement. The dose was increased cycle by cycle in a prospective manner.

Lomustine (chloroethylnitrosourea [CCNU]), ifosfamide, bleomycin, vincristine, and cisplatin (CIBO-P) is an effective regimen for patients with poor prognostic refractory or multiple disease recurrent aggressive non-Hodgkin lymphoma.

Background: The current study was designed to assess the activity and safety of a novel combination therapy for patients with recurrent or refractory aggressive non-Hodgkin lymphoma (NHL).

Methods: Forty-three consecutive patients with recurrent or refractory aggressive NHL were treated with lomustine (chloroethylnitrosourea [CCNU]; 60 mg/m2 on Day 1), ifosfamide (1.5 g/m(2 on Days 1, 2 and 21, 22), bleomycin (5 mg/m2 on Days 1, 5 and 21, 25), vincristine (1.

Design and development of new combinations of the CMF agents with taxanes (paclitaxel or docetaxel) in advanced breast cancer: a feasibility study.

Aims And Background: We previously designed and tested combinations made up of the CMF agents, two at a time by rotation, and of doxorubicin or epirubicin. The present study was aimed to similarly test new combinations made up of the CMF agents, two at a time by rotation, and paclitaxel or docetaxel.

Methods: The doses of each taxane were escalated with the objective of reaching at least a single dose level of 90 mg/m2 of paclitaxel and 45 mg/m2 of docetaxel on days 1 and 8 of each four-week cycle.

Early detection of recurrences in the follow-up of primary breast cancer in an asymptomatic or symptomatic phase.

Aims And Background: Periodic follow-up after primary treatment for breast cancer is a common procedure for the early detection of recurrent disease in the asymptomatic state. Anyway, there is no clinical evidence that treatment of metastases may improve the prognosis if applied in the asymptomatic state. The aim of the present study was to investigate the modality of detection of the first relapse in the asymptomatic vs the symptomatic state.

A randomized trial of exemestane after two to three years of tamoxifen therapy in postmenopausal women with primary breast cancer.

Background: Tamoxifen, taken for five years, is the standard adjuvant treatment for postmenopausal women with primary, estrogen-receptor-positive breast cancer. Despite this treatment, however, some patients have a relapse.

Methods: We conducted a double-blind, randomized trial to test whether, after two to three years of tamoxifen therapy, switching to exemestane was more effective than continuing tamoxifen therapy for the remainder of the five years of treatment.

P-CHOP: cisplatin (P) added to the standard CHOP regimen as first-line treatment for aggressive non-Hodgkin lymphoma: a single-institution phase II study.

We designed the P-CHOP regimen, which involves the addition of cisplatin (P) to the standard CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) regimen, and investigated its activity and its toxicities in a single institution phase II study. Twenty-two consecutive patients with untreated, aggressive, stage I-IV non-Hodgkin lymphoma were enrolled in the study. Cisplatin was administered at a dose of 40 mg/m2 on days 1 and 2, every 3 weeks; the dose and schedule of the other agents were identical to those used in the standard CHOP regimen.

Adjuvant chemotherapy in early breast cancer: optimal and suboptimal anthracycline-containing regimens.

We hypothesized that the advantage of adjuvant anthracycline-containing regimens over the conventional CMF combination found by the Early Breast Cancer Trialists' Collaborative Group overview may depend on the 'additive' or 'substitutive' nature of the administration of anthracycline in the experimental arm. The aim of this study was to explore this hypothesis. By means of computerized and hand searches, we identified 21 published randomized trials comparing early breast cancer adjuvant chemotherapies with and without anthracycline, and divided them into those in which the use of anthracycline was substantially 'additive' or substantially 'substitutive'.

Cisplatin, epirubicin, leucovorin and 5-fluorouracil (PELF) is more active than 5-fluorouracil, doxorubicin and methotrexate (FAMTX) in advanced gastric carcinoma.

Background: 5-Fluorouracil (5-FU), doxorubicin and methotrexate (FAMTX) and cisplatin, epirubicin, leucovorin and 5-FU (PELF) have both been reported to be superior to the combination 5-FU, doxorubicin and mitomycin C (FAM) in advanced gastric carcinoma. On the basis of the presence and dose intensity of the included agents, we hypothesised that PELF would be superior to FAMTX.

Patients And Methods: Two hundred patients with untreated advanced gastric carcinoma were randomised to receive PELF or FAMTX for a maximum of six cycles or until disease progression.

Treatment of metastatic malignant melanoma with dacarbazine plus tamoxifen, or vindesine plus tamoxifen: a prospective randomized study.

This study aimed to verify whether the advantage in terms of response rate and survival of dacarbazine plus tamoxifen over dacarbazine alone in metastatic malignant melanoma reported in a previous randomized trial was due to a specific interaction of dacarbazine with tamoxifen. A total of 125 patients with locoregional or disseminated malignant melanoma were randomized to receive dacarbazine (250 mg/m(2) days 1-5 every 3 weeks) plus tamoxifen (arm A) or vindesine (3 mg/m(2) every week for 6 weeks, then every 2 weeks) plus tamoxifen (arm B). Of the 125 randomized patients, 57 and 59 were evaluable in arm A and B, respectively.

Epirubicin versus CMF as adjuvant therapy for stage I and II breast cancer: a prospective randomised study.

We compared a relatively short regimen of monochemotherapy with epirubicin versus polychemotherapy with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as adjuvant treatment for stage I and II breast cancer patients. 348 patients with oestrogen receptor negative (ER-) node negative and ER- or ER+ node-positive with <10 nodes were accrued. CMF was given intravenously (i.

Randomized trial comparing cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) with rotational CMF, epirubicin and vincristine as primary chemotherapy in operable breast carcinoma.

Background: According to the overview of Early Breast Cancer Trialists' Collaborative Group, anthracycline containing regimens are superior to cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) as adjuvant chemotherapy for breast carcinoma, but no comparative information is available in terms of primary chemotherapy. In the current randomized controlled trial, the authors compared CMF with a chemotherapy regimen including CMF, epirubicin, and vincristine (CMFEV).

Methods: Two hundred eleven patients with Stages I and II palpable breast carcinoma and tumor diameter > 2.

Independent clinical trials: a commentary.

The so-called norms of good clinical practice have been incorporated into the Italian regulatory legislation governing clinical trials sponsored by pharmaceutical companies, but there are no legislative provisions governing independent clinical trials: ie those not sponsored by the industry. The pharmaceutical industry has recently increased considerably its commitment to sponsored trials by establishing a series of economic relationships with individual researchers and hospital or university institutions. It has also set up and strengthened a series of bodies and service companies with the aim of making the clinical trials "machine" more efficient.

Biological variables in non-small cell lung cancer: comparison between immunocytochemical determination on fine needle aspirates from surgical specimens and immunohistochemical determination on tissue sections.

A number of biological and predictive markers of non-small cell lung cancer (NSCLC) have been sought, but these have so far been mainly evaluated on surgically resected specimens. Given that fine needle aspiration biopsy (FNAB) is being increasingly used in the diagnosis of NSCLC, its application could be extended to the immunocytochemical detection of biological parameters at the time of diagnosis before surgery. In order to assess the reliability of estimating biological markers on fine needle aspirates (FNAs) from NSCLC, the aim of this study was to compare Ki67 growth fraction, p53 and bcl-2 protein expression as revealed by the immuncytochemical assessment of FNAs obtained from surgical samples with the immunohistochemical results obtained from the corresponding histological sections.

Vinorelbine combined with paclitaxel infused over 96 hours (VI-TA-96) for patients with metastatic breast carcinoma.

Background: Vinorelbine (VI) and paclitaxel (TA) are among the most active single agents in the treatment of patients with breast carcinoma, and both have microtubules as their cytotoxic target. This Phase I-II study combined these 2 agents and used a 96-hour intravenous (i.v.

Comparison of the results of immunocytochemical assays for biologic variables on preoperative fine-needle aspirates and on surgical specimens of primary breast carcinomas.

Background: Fine-needle aspiration biopsy (FNAB) is a well-documented procedure for the diagnosis and biologic characterization of breast carcinoma. In order to compare the immunocytochemical expression of biologic parameters on cytology and on histology, estrogen receptor (ER) and progesterone receptor (PgR) status, p53 protein expression, and Ki67 growth fraction were evaluated on presurgical fine-needle aspirates (FNAs) from breast carcinoma patients and on the corresponding surgical samples prior to any systemic therapy.

Methods: FNAs were performed on 104 patients with primary breast carcinoma at the time of diagnosis and subjected to immunocytochemical evaluation of ER, PgR, p53, and Ki67.

Comparison of CMF (cyclophosphamide, methotrexate, and 5-fluorouracil) with a rotational crossing and a sequential intensification regimen in advanced breast cancer: a prospective randomized study.

The Italian Oncology Group for Clinical Research tested two experimental chemotherapy strategies in an attempt to improve the results achievable with conventional chemotherapy in metastatic breast cancer. One hundred sixty-two patients were randomly allocated as follows: (a) to the conventional cyclophosphamide, methotrexate, 5-fluorouracil chemotherapy regimen (CMF); (b) to a rotational crossing program (ROT-CROSS); or (c) to a sequential intensification program (SEQ-INT). The same single agents (C, M, F, cisplatin, etoposide, and doxorubicin) were administered in both experimental arms, but following a different policy.
