Objectives: Acceptance of childhood vaccination varies between societies, affecting worldwide vaccination coverage. Low coverage rates are common in indigenous populations where parents often choose not to vaccinate their children. We aimed to gain insight into reasons for vaccine acceptance or rejection among Warao Amerindians in Venezuela.

Background: To determine whether the cost of prophylactic antibiotics during chemotherapy is offset by cost savings due to a decreased incidence of febrile leukopenia (FL).
Patients And Methods: Small-cell lung cancer (SCLC) patients were randomised to standard or intensified chemotherapy with granulocyte colony-stimulating factor to assess the impact on survival (n = 244). In addition, patients were randomised to prophylactic ciprofloxacin and roxithromycin or placebo to assess the impact on FL (n = 161).
Purpose: To assess the impact on survival of increasing dose-intensity (DI) of cyclophosphamide, doxorubicin, and etoposide (CDE) in small-cell lung cancer (SCLC).
Patients And Methods: Previously untreated SCLC patients were randomized to standard CDE (cyclophosphamide 1,000 mg/m(2) and doxorubicin 45 mg/m(2) on day 1, and etoposide 100 mg/m(2) on days 1 to 3 every 3 weeks, for five cycles) or intensified CDE (cyclophosphamide 1,250 mg/m(2) and doxorubicin 55 mg/m(2) on day 1, and etoposide 125 mg/m(2) on days 1 to 3 with granulocyte colony-stimulating factor [G-CSF] 5 micro g/kg/d on days 4 to 13 every 2 weeks, for four cycles). Projected cumulative dose was almost identical on the two arms, whereas projected DI was nearly 90% higher on the intensified arm.
Background: Surgical or medical castration and antiestrogenic treatment with tamoxifen are common endocrine treatments for premenopausal women with breast cancer. However, tamoxifen therapy induces high levels of plasma estradiol, with unknown long-term effects. In this study, we investigated the effect of combining estrogen suppression with the luteinizing hormone-releasing hormone agonist buserelin and estradiol receptor blockade with tamoxifen to determine whether the high estradiol levels induced by tamoxifen could be reduced and whether the antitumor effects would be better.

Some early clinical studies in patients with advanced breast cancer did seem to support these findings. Therefore, the efficacy of estrogenic recruitment followed by chemotherapy was compared with that of chemotherapy alone in a randomized phase III study in women with lymph node-positive primary breast cancer.

She was suffering from an unspecified interstitial lung disease, papillary thyroid carcinoma which had been treated, hypoparathyroidism after thyroidectomy for which she was receiving dihydrotachysterol and calcium, and atrial fibrillation and congestive heart failure as a result of mitral stenosis. Shortly after mitral valve replacement she developed a severe hypercalcemia (serum calcium 5.

Presently, the most effective anti-emetic regimen is a combination of a 5HT3 antagonist plus dexamethasone. We, therefore, assessed the sustainment of efficacy of such a combination in 125 patients, scheduled to receive cisplatin > or = 70 mg m(-2) either alone or in combination with other cytotoxic drugs.

A secondary endpoint was to assess the toxicity of alternate day doses of this treatment. One hundred and seventy seven patients in complete or nearly-complete response following chemotherapy with or without thoracic radiotherapy were studied.

Because oestrogens may counteract the anti-tumour effects of such treatment, the combination of an anti-oestrogen (tamoxifen), a somatostatin analogue (octreotide) and a potent anti-prolactin (CV 205-502) might be attractive. In this respect, we performed a first exploratory long-term study on the feasibility of combined treatment and possible clear differences in endocrine and anti-tumour effects during such combined treatment vs standard treatment with tamoxifen alone.

Materials And Methods: A total of 335 eligible patients were randomized between five courses of CDE chemotherapy followed by thoracic irradiation 50 Gy in 20 daily fractions (S) and the same total dose of chemotherapy and irradiation split into four courses of five daily fractions delivered on days 14 to 21 of the second and subsequent chemotherapy courses (A). Patients had a median age of 61 years (range, 33 to 75); 224 (66%) were male; the Eastern Cooperative Oncology Group (ECOG) performance status (PS) was 0 or 1 in 311; and 254 had weight loss less than 10%.
Purpose: A potential application of hematopoietic growth factors is to obtain an increased dose-intensity. This can be achieved by either higher doses of chemotherapy with standard intervals, or by standard doses with shorter intervals. The potential of these approaches has not been investigated systematically.

Patients And Methods: Two hundred twenty-five NSCLC patients were randomized to receive VM26 120 mg/m2 on days 1, 3, and 5 or 360 mg/m2 on day 1 only, either as a single drug or in combination with cisplatin 80 mg/m2 on day 1. Cycles were repeated every 3 weeks.
A total of 14 patients with platinum-resistant advanced epithelial ovarian cancer were treated with a continuous infusion of high-dose 5-fluorouracil (5-FU, 1200 mg/m2 per day) for 2 consecutive days weekly for 4 weeks and, thereafter, every 2 weeks in combination with a push injection of folinic acid (20 mg/m2) given just before 5-FU and after 24 h. No objective response was documented, and only five patients showed stable disease. The median survival was 6.

The authors investigated the clinical efficacy of combining these three agents for patients in this group.
Methods: Forty-five patients were administered outpatient high-dose 5-FU, 60 mg/kg/48 hours (2400 mg/m2/48 hours) continuous intravenous infusion on days 1 and 2; LV, 90 mg orally every 6 hour, 8 times during 5FU infusion; and recombinant IFN-alpha-2b, 10 x 10(6) IU/dose subcutaneously on days 1, 3, and 5.
Purpose: The present study investigates the role of short chemotherapy (five cycles) versus prolonged (12 cycles) chemotherapy in small-cell lung cancer (SCLC).
Patients And Methods: Six hundred eighty-seven patients with SCLC were registered in a multicenter study to receive five cycles of chemotherapy consisting of cyclophosphamide 1 g/m2 on day 1, doxorubicin 45 mg/m2 on day 1, and etoposide 100 mg/m2 on days 1, 3 and 5 (CDE), every 3 weeks. Four hundred thirty-four nonprogressing patients after five cycles of chemotherapy were randomized either to receive seven further cycles of the same chemotherapy or to follow-up.
Background: FAMTX (5-fluorouracil, adriamycin, methotrexate) is one of the most effective drug combinations in gastric cancer. Therefore, modifications of FAMTX appear of interest and the FEMTX-P regiment was conceived.
Patients And Methods: Fifty patients with unresectable locally advanced and/or metastatic gastric carcinoma were treated with methotrexate 1500 mg/m2 i.
Eighty-one patients with small cell lung cancer (SCLC) with a survival of more than 2 years after start of chemotherapy were studied. Twenty-six of the 28 patients who died of relapsed SCLC had in fact relapsed before two years and of the 55 who had not then only two (4%) relapsed subsequently. It is stressed that with such observations treatment related factors should be taken in account.

In our study high-dose continuous infusion 5-FU (60 mg/kg per 48 hours), oral folinic acid (FA) (8 x 90 mg during 5-FU), and IFN-alpha three times weekly were combined. Because the addition of IFN-alpha has not been tested before, and serious toxicity of 5-FU plus IFN-alpha therapy has been reported, the IFN-alpha dose was escalated from 3 to 10 million units (MU)/dose in the first 11 patients.
