[show abstract][hide abstract] ABSTRACT: The combination of vinorelbine and doxorubicin, two very active drugs in metastatic breast cancer, has demonstrated impressive results in terms of efficacy, at the price of cardiac toxicity (10% grades 2-4) due to the cumulative dose of doxorubicin delivered. This study was designed to divide the dose of doxorubicin into two administrations (day 1 and 8) in order to reduce the toxicity profile, while keeping the same level of efficacy.
Thirty-eight chemotherapy-naïve metastatic breast cancer patients entered into the study and were treated with vinorelbine, 25 mg/m(2), and doxorubicin, 25 mg/m(2), both on days 1 and 8, every 3 weeks. Thirty-seven patients were evaluable for efficacy and 38 for tolerance; 71% of the patients presented with visceral metastases.
Patients received a median of seven cycles and 94.9% of the intended dose intensity of both drugs. Grade 3-4 neutropenia was reported in 10% of cycles. Alopecia was reported in 89.5% of the patients, and grade 2 nausea/vomiting in 9.3% of the cycles. Grade 1-2 cardiac toxicity was noted in 23.7% of the patients. The objective response rate of the patients was 78.4% (nearly 81% for patients with visceral metastases); the median duration of response was 11.6 months, the median survival 21.6 months, and the 1-year survival 75.2%.
This schedule of vinorelbine/doxorubicin represents an active and well-tolerated combination.

[show abstract][hide abstract] ABSTRACT: Twenty women with advanced breast cancer were treated with Docetaxel. In 50% of cases partial remission with median duration of 7.1 months was obtained. The median survival time was 18 months. Stabilization of disease with median duration of 5.5 months was obtained in 45%. The median survival in this group of patients was 15.3 months. The pervious antracycline-based chemotherapy did not influenced the results. The most common side effect was neutropenia (G3 in 80% of pts) and alopecia, but the chemotherapy tolerance was satisfactory.
[show abstract][hide abstract] ABSTRACT: The efficacy and toxicity profile of gemcitabine was evaluated in this phase II study of chemonaive patients with locally advanced and metastatic non-small cell lung cancer (NSCLC). Eighty patients (62 males, 18 females) were entered into this study. The disease stage was IIIA in ten patients, IIIB in 32, and IV in 38 patients. The median age was 61 (range 41 - 78). Karnofsky performance status was > or = 80 in 88% of patients. All patients were chemonaive, but five patients had received prior radiotherapy and 34 patients had undergone prior surgery. Gemcitabine 1250 mg/m2 was given as a 30-min intravenous infusion on days 1, 8, and 15 of a 28-day cycle. Patients received up to nine cycles (median three cycles). Of 872 doses 815 (93%) were administered without dose delay or modification. Of the 80 patients enrolled, 76 were evaluable for efficacy analysis, and 16 patients had a partial response for an overall response rate of 21.1% (95% CI, 11.9-30.3%). A further 47 patients (61.8%) had stable disease. Partial responses were seen in eight of 41 stage III patients (19.5%) and in eight of 35 stage IV patients (22.9%). The median time to progressive disease was 4.6 months. Median survival for all 80 patients was 7.1 months. Haematological toxicity was mild with grade 3 4 neutropenia in 6.3% of patients, grade 3 thrombocytopenia in 3.8% of patients, and grade 3 anaemia in 2.5% of patients. Grade 3 non-laboratory toxicity was: somnolence (1.3% of patients), infection (1.3%), nausea and vomiting (6.4%) and dyspnoea (5.1%). This study confirms that single-agent gemcitabine is active in advanced NSCLC and its well-tolerated safety profile makes it particularly suited to outpatient use.

[show abstract][hide abstract] ABSTRACT: A total of 530 patients were treated in this multicenter, double-blind, double-dummy, parallel group study to compare the anti-emetic efficacy and safety of a once daily ondansetron oral regimen with a once daily i.v. dosing regimen over a 24 h period, administered to patients prior to receiving cisplatin (50 mg/m2 or greater) chemotherapy. Patients were randomized to receive a single dose of ondansetron plus dexamethasone given either orally (ondansetron 24 mg and dexamethasone 12 mg, n=262) or i.v. (ondansetron 8 mg and dexamethasone 20 mg, n=268). Complete control of emesis (i.e. no emetic episodes, no rescue and no premature withdrawal) was achieved for 85% of patients (224 of 262) in the oral group and 83% (223 of 268) in the i.v. group. No nausea was reported in 70% of patients in the oral group and 68% in the i.v. group. There were no statistically significant differences between the two groups for any of the assessments of efficacy, which included time to first emetic episode, number of emetic episodes and the worst grade of nausea occurring over the 24 h study period. Once daily ondansetron oral and i.v., in combination with dexamethasone, was well tolerated in this study. In conclusion, once daily oral ondansetron 24 mg plus dexamethasone is equally effective in the control of emesis and nausea induced by highly emetogenic chemotherapy as once daily ondansetron 8 mg i.v. plus dexamethasone.

Objective response rate (CR + PR) was 6.4%. 46.8% patients had stable disease with median time of stabilisation 6.9 m. Because of low toxicity and non satisfactory results of second line chemotherapy tamoxifen seems to be a useful treatment for this group of patients.

[show abstract][hide abstract] ABSTRACT: Twenty patients with advanced ovarian cancer were treated with chemotherapy PC (cisplatin 100 mg/m2, cyclophosphamide 1000 mg/m2) administered with amifostine. Sixty five percent of patients had objective response with 25% complete response rate. Tolerance of treatment was satisfactory. Only in 1 patients side effects were the reason of treatment interruption. Amifostine markedly decreases chemotherapy toxicity, mainly hematological and does not seem to influence the efficacy of chemotherapy.

[show abstract][hide abstract] ABSTRACT: The 1990s have established the contribution of multimodality therapy in the management of IIIb noninflammatory breast cancer (IIIb NIBC), by reducing the odds of recurrence and death.
A total of 300 women with IIIb NIBC received a multimodality therapy. The treatment consisted of neoadjuvant chemotherapy [FAC (5-fluorouracil, Adriamycin, cyclophosphamide) regimen], radical (Halsted) mastectomy or modified (Patey mastectomy), postoperative radiotherapy, and adjuvant chemohormone therapy [FAC regimen + cyclophosphamide, 5-fluorouracil and methotrexate (CMF) regimen or Tamoxifen].
Complete or partial clinical response (CR or PR) after neoadjuvant chemotherapy was obtained in 83% patients. Ninety-nine patients (33%) survived 5 years without evidence of disease (NED). The uni- and multivariate analyses factors that had significant influence on the treatment results were: clinical response to neoadjuvant chemotherapy, pathological tumor size, and microscopical status of the axillary lymph nodes.
We conclude that neoadjuvant FAC regimen chemotherapy is very effective in producing objective tumor regression and offers the benefit of radical mastectomy to patients with previously unresectable IIIb NIBC.

[show abstract][hide abstract] ABSTRACT: Current evidence suggests that epoetin alpha administration is well tolerated and effective in the management of anemia of cancer and cancer chemotherapy. An open-label, multinational, non-comparative study was conducted in 215 cancer patients with anemia secondary to chemotherapy with platinum- or non-platinum-based combinations. Epoetin alpha was administered s.c. (150 IU/kg three times/week) for a planned period of 16 weeks. The response rate of epoetin alpha, defined as an increase in hemoglobin level of 2 g/dl or more from baseline, was 67%. The rate of response was not related to the chemotherapy regimen administered (platinum or non-platinum based). The percentage of patients transfused and the transfusion rate during epoetin alpha treatment were reduced. Transfusional need was eliminated in 64 (75%) of the 85 patients transfused before the study start, after 1 month of therapy. Quality of life, assessed using a visual analog scale, improved markedly in patients who experienced a hematological response. These patients also experienced a statistically significant (p < 0.0001) improvement in mean WHO performance score. These findings indicate that epoetin alpha is a well tolerated and effective agent which increases hemoglobin concentration and reduces transfusion requirements in anemic cancer patients receiving chemotherapy.
[show abstract][hide abstract] ABSTRACT: The study was planned to compare, in a prospective double-blind randomized trial, the efficacy and safety of toremifene (TOR) and tamoxifen (TAM) in post-menopausal patients with advanced breast cancer who have not had prior systemic therapy for advanced disease. Four hundred and fifteen post-menopausal patients with oestrogen receptor (ER)-positive or ER-unknown advanced breast cancer were randomly assigned to receive daily either 60 mg TOR or 40 mg TAM. The patients were stratified to measurable and non-measurable but evaluable groups. They were assessed for response to therapy, time to progression (TTP), time to treatment failure (TTF), response duration, overall survival and drug toxicity. Two hundred and fourteen patients were randomized into TOR and 201 into TAM treatment. The response rate (complete + partial) was 31.3% for TOR and 37.3% for TAM (P = 0.215). The 95% confidence interval (CI) for the 6% difference was -15.1% to 3.1%. The median TTP was 7.3 months for TOR and 10.2 months for TAM (P = 0.047). The 95% CI for the hazard ratio of 0.80 was 0.64-1.00. A percentage of the TOR patients (9.8%) and the TAM patients (18.9%) discontinued the treatment prematurely (P = 0.011) for various reasons. Consequently, the median TTF of 6.3 vs 8.5 months did not differ significantly (P = 0.271). The hazard ratio was 0.89 and the subsequent 95% CI 0.73-1.09. The median overall survival was 33.0 months for TOR and 38.7 months for TAM (P = 0.645). The hazard ratio was 0.94 with 95% CI of 0.73-1.22. The transient difference in TTP may be related to an imbalance in ER content of the tumours. When only patients with ER-positive tumours were considered (n = 238), no difference between two treatments was seen (P = 0.578). TAM was associated with an overall slightly higher frequency of adverse drug reactions than TOR (44.3 vs 39.3%) and a higher discontinuation rate due to these events (3.5% vs 0.9%). Treatment-emerged moderate dizziness (P = 0.026) and cataracts (P = 0.026) were more frequent among TAM than among TOR patients. In conclusion, TOR (60 mg day(-1)) and TAM (40 mg day(-1)) are equally effective and safe in the treatment of advanced post-menopausal ER-positive or ER-unknown breast cancer.

[show abstract][hide abstract] ABSTRACT: The results of advanced breast cancer therapy with tamoxifen have been evaluated. The objective response to the drug has been achieved in 32 (31.7%) patients, and a 2-year survival in 52% of cases. A correlation between the localization of lesions and response rate has been found. The best results have been achieved in localized lesions and lymph nodes metastases. Low toxicity of the drug enables achievement of results comparable to those seen in all types of the hormonal therapy, except androgens.

[show abstract][hide abstract] ABSTRACT: The aim of the present study is the evaluation of late hematological complication in patients who received aggressive chemotherapy, and were observed 3, 5 and 10 years after treatment was completed. In the group of 35 patients, besides high percent of early hematological complications, there was only one case of anemia grade 2 (acc. to WHO score). We concluded that the hematological recovery after aggressive chemotherapy was satisfactory. No secondary hematological malignancies have been found.

[show abstract][hide abstract] ABSTRACT: During 10 years patients with malignant melanoma were followed up after radical removal of primary tumour and metastatic regional lymph nodes, the half of whom was given immunomodulation with the preparation Poly-A Poly-U in a controlled clinical trial. It was found that the performed immunomodulation exerted slight effect on the course of malignant melanoma causing later development of recurrence, less dynamic course of the disease, longer asymptomatic periods in relation to the control group. No effect of the drug administration was observed on longterm survival.
[show abstract][hide abstract] ABSTRACT: In a group of 30 patients with the diagnosis of malignant non-Hodgkin lymphoma of high histological malignancy, a prospective randomized study was carried out concerning the effectiveness and toxicity of the CHOP chemotherapy using adriamycin vs epirubicin. The effectiveness and tolerance of both treatment programmes are comparable. Good tolerance of the used epirubicin dose encourages to its increase in combined chemotherapy programmes in order to achieve higher therapeutic effectiveness.
