Background: Premenopausal patients treated with adjuvant chemotherapy often develop early menopause and thus, may encounter significant bone loss. We studied the long-term effects of chemotherapy-induced ovarian dysfunction on bone mineral density in breast cancer patients.
Material And Methods: The effect of menstrual status after adjuvant chemotherapy on bone mineral density (BMD) was examined in 29 premenopausal breast cancer patients.
Purpose: We have previously reported that 3-year adjuvant clodronate treatment prevents bone loss in breast cancer patients. Here we report the 10-year follow-up data of clodronate in the prevention of treatment-related osteoporosis in women with early-stage breast cancer.
Patients And Methods: Two hundred sixty-eight pre- and postmenopausal, node-positive breast cancer patients were randomly assigned to clodronate, 1.
5-Fluorouracil (5-FU)-based chemotherapy is frequently associated with diarrhoea. We compared two 5-FU-based regimens and the effect of Lactobacillus and fibre supplementation on treatment tolerability. Patients diagnosed with colorectal cancer (n=150) were randomly allocated to receive monthly 5-FU and leucovorin bolus injections (the Mayo regimen) or a bimonthly 5-FU bolus plus continuous infusion (the simplified de Gramont regimen) for 24 weeks as postoperative adjuvant therapy.

Methods: We randomly assigned 1010 women with axillary-node-positive or high-risk node-negative cancer to receive three cycles of docetaxel or vinorelbine, followed by (in both groups) three cycles of fluorouracil, epirubicin, and cyclophosphamide.
Purpose: Adjuvant chemotherapy followed by tamoxifen is a standard treatment option for women with intermediate or high-risk hormone receptor-positive breast cancer. Premenopausal women treated with chemotherapy often develop early menopause and thus, enter a period of accelerated bone loss. We conducted a prospective study of the effect of sequential adjuvant therapy with chemotherapy followed by tamoxifen on bone mineral density (BMD) in premenopausal patients.

Recently, clodronate has been studied in adjuvant settings in primary breast cancer. However, long-term effect of adjuvant clodronate on bone histology has not been reported, whereas bone mineral density studies have been published.

Purpose: Serum postoperative matrix metalloproteinase 2 (MMP-2) level is a predictor of outcome in node positive breast cancer and can be used to stratify patients into low and high risk groups. Our aim was to determine how clodronate treatment influences MMP-2 associated clinical outcome.
Patients And Methods: Women with primary node-positive breast cancer were randomized to control group or to receive oral clodronate for 3 years.
Purpose: Define the maximum tolerated dose (MTD), tolerability, and efficacy of gemcitabine given concomitantly with radiotherapy in patients with locally advanced pancreatic cancer.
Methods And Materials: Patients were required to have locally advanced T1-T3 resectable pancreatic cancer. Gemcitabine, given twice weekly before irradiation as a 30-min infusion, was tested at 3 dose levels: 20, 50, and 100 mg/m(2).
Chemotherapy-induced ovarian failure causes rapid bone loss in premenopausal women with early breast cancer. The aim of the present study was to investigate the effect of intravenous intermittent clodronate during adjuvant chemotherapy in prevention of this rapid bone loss. 45 premenopausal women with early stage breast cancer were treated with adjuvant chemotherapy.

Background & Aims: Bowel mucosal injury associated with 5-fluorouracil (5-FU) treatment might result in secondary lactose intolerance. The frequency and clinical significance of 5-FU-related hypolactasia are unknown.
Methods: One hundred fifty patients randomly assigned to receive 1 of 2 adjuvant 5-FU-based chemotherapy regimens, the Mayo regimen or the simplified de Gramont regimen, were studied for lactose tolerance by using an oral lactose absorption test, a symptom questionnaire, treatment-related toxicity, and Subjective Global Assessment of Nutritional Status questionnaire before, during, and 2 and 6 months after chemotherapy for colorectal cancer.
In all, 146 premenopausal women with early stage breast cancer were treated with adjuvant chemotherapy. In addition, 5-year tamoxifen treatment was started after chemotherapy to those 112 patients with hormone-receptor-positive tumours while those with hormone-receptor-negative tumours received no further therapy. The serum lipid levels were followed in both groups.

Experimental Design: MMP-2 and MMP-9 levels were quantitatively measured in serum after surgery from 133 patients with primary node-positive breast cancer using enzyme-linked immunoassays. All of the patients received adjuvant therapy, postmenopausal endocrine treatment (tamoxifen or toremifen for 3 years) and premenopausal six cycles of CMF chemotherapy.
A phase II study was conducted to assess the toxicity and response rate of vinorelbine (NavelbineR) combined with epirubicin and fluorouracil (NEF) in metastatic breast cancer. Vinorelbine was delivered at a dose of 25 mg/m2 on days 1 and 8, epirubicin at 60 mg/m2 on day 1 and fluorouracil at 600 mg/m2 on day 1, at 3-week intervals. Forty consecutive ambulant patients with breast cancer with measurable metastases were treated with a total of 310 cycles (median 8) as first-line therapy.

Patients And Methods: Vinorelbine 40 mg/m(2) was given as follows: 20 mg/m(2) on days 1 and 8 (group 1); 30 mg/m(2) on day 1 and 10 mg/m(2) on day 8 (group 2); or 40 mg/m(2) on day 1 (not exeeding 60 mg/m(2)) (group 3). The methotrexate dose was 40 mg/m(2) on day 1 and the fluorouracil dose 600 mg/m(2) on days 1 and 8.
We studied longitudinally inflammatory reactions and serum C-reactive protein (S-CRP) levels in 52 colorectal cancer patients treated with a median of six 3-weekly cycles of raltitrexed 1.5-3.0 mg m(-2) combined with oral carmofur (1-hexylcarbomoyl-5-fluorouracil) 300-400 mg m(-2) on cycle days 2-14.

In this study we report bone mineral density (BMD) changes during clodronate and antioestrogen treatment in women with breast cancer having discontinued hormone replacement therapy (HRT) at the time of operation compared to women who had not used HRT immediately before the operation. 61 postmenopausal women with operable breast cancer were treated with the adjuvant antioestrogen tamoxifen 20 mg or toremifene 60 mg daily for 3 years. All patients were randomized to clodronate (1.

cDNA microarray analysis was used to screen for gene expression alterations in human osteosarcoma cell lines. The analysis using three cell lines revealed changes in the expression of several genes in comparison with normal human osteoblasts. Among the 5,184 sequences that were analyzed, 35 showed aberrant expression in all the cell lines.
