Herein, we examined the baseline tumor angiogenic profile of patients with metastatic breast carcinoma (MBC) in a prospective-retrospective translational research study. The interplay between the angiogenic factors expressed in the tumors and their prognostic value in MBC were investigated. Tumor tissues from patients with MBC treated with weekly docetaxel (n=159) were examined by immunohistochemistry for VEGF-A, VEGF-C, VEGFR-1, VEGFR-2, VEGFR-3 and osteopontin (OPN) and by mRNA analysis for expression of VEGF-A, VEGFxxxa, VEGFxxxb, VEGF-C, thrombospondin-1 (THBS-1), hypoxia-inducible factor-1A (HIF-1A) and von Hippel-Lindau (VHL) genes. Associations between these parameters and outcome were statistically analyzed. Statistically significant correlations were identified between almost all biomarkers examined in continuous form, particularly at the mRNA level: VEGF-A with VEGFxxxa (rho=0.70); VEGF-C with VEGFxxx...

This multicenter phase II study was conducted to evaluate the safety and efficacy of the combination of pegylated liposomal doxorubicin (PLD) and paclitaxel, as first-line treatment in patients with advanced STS. In all, 42 patients with locally advanced or metastatic STS, median age 54 years and median Eastern Cooperative Oncology Group performance status (PS) 1 were treated with PLD 45 mg m(-2) and paclitaxel 150 mg m(-2), every 28 days for a total of six cycles. Histological types included mainly leiomyosarcomas (43%), malignant fibrous histiocytomas (14%) and liposarcomas (12%). At study entry, 69% of patients had distant metastases. Overall response rate was 16%, including one complete (CR 2%) and six partial responses (PRs 14%), while an additional 14 patients had disease stabilization (SD 33%). At median follow-up 41.5 months, median time to pr...

We studied the toxicity profile of postoperatively administered CPT-11 plus leucovorin (LV)-modulated 5FU and radiotherapy in patients with rectal cancer. Thirty-seven patients with Dukes' B2 and C rectal adenocarcinoma were treated with CPT-11, 80 mg/m2 ii.v. over 90 minutes followed by LV 200 mg/m2 over 2 hours and 5FU 450 mg/m2 i.v.-bolus weekly for 4 weeks followed by a 2-week rest period. One cycle included 4 infusions. The first cycle of chemotherapy was followed by pelvic radiation to a total dose of 45 Gy to the whole pelvis and a boost of 5 Gy to the tumor bed. 5FU was administered daily as a rapid infusion during the first 3 as well as the last 3 days of radiotherapy. CPT-11 plus LV-modulated 5FU was continued for a total of 6 cycles or consent withdrawal. The main toxicity...

We assessed the efficacy and safety profile of a docetaxel (Taxotere; Sanofi-Aventis, France), fluorouracil (FU), and leucovorin (LV) combination (TFL), as first-line chemotherapy in patients with advanced gastric cancer. Methods. Fifty-eight patients with advanced gastric cancer were entered in this phase II study. The chemotherapy regimen (TFL) was administered in an outpatient setting as follows: docetaxel 70 mg/m 2 on day 1 and FU 500 mg/m 2 and LV 300 mg/m 2 on days 1 to 3, every 3 weeks for six cycles. Results. On an intent-to-treat basis, 4 complete (7%) and 11 partial responses (19%) were observed, with an objective overall response rate of 26%; in addition, 22 patients (38%) had stable and 15 (26%) had progressive disease. For 6 (10%) patients, response could not be evaluated. Responses were noted at all metastatic sites. With a median follow-up of 55 months, median survival was 9 months; median time to progression, 5.9 months; and median duration of response, 10 months. Toxicity was manageable and no toxic death was reported. Neutropenia was the most frequent severe toxicity and occurred in 30% of the patients. The main nonhematologic toxicities were alopecia (76%), diarrhea (30%), and stomatitis (30%). Conclusion. The results of this phase II study seem to indicate that the TFL regimen has moderate activity in patients with advanced gastric cancer, with acceptable toxicity.

Patients (n=32) with brain metastases were treated with TMZ 150 mg/m2/day (chemotherapy-pretreated) or 200 mg/m2/day (chemotherapy-naive) for 5 days, combined with CDDP 75 mg/m2 on day 1, every 28 days. Primary tumor sites included breast cancer (n=15), lung cancer (n=12) and other (n=5). Twenty-seven patients had received prior chemotherapy for extracranial disease and 17 had prior radiotherapy to the brain. One patient (3.1%) with non-small cell lung cancer (NSCLC) achieved complete response. Nine patients (28.1%; six with breast cancer, two with melanoma and one with NSCLC) achieved a partial response and five patients (16%) had stable disease. Median OS was 5.5 months and median TTP 2.9 months. One patient died from septicemia/neutropenic fever. Grade III-IV toxicities included anemia (9%), leukopenia (6%), thrombocytopenia (3%), renal toxicity (3%), headache (3%), fatigue (3%), nausea (3%), vomiting (3%), and alopecia (6%). TMZ combined with CDDP is an active and well-tolerated combination in patients with brain metastases from solid tumors.

The antibody was labeled with Tc-99m using the 2-Iminothiolane method. All patients underwent transurethral resection of the bladder tumor within 12-20 h following intravesical administration of 99m-Tc-HMFG1. The presence of the radiolabeled MAb in the circulation was studied by measuring the radioactivity in the serum for a period up to 20 h. Three of 10 patients underwent immunoscintigraphy (SPECT) 2-3 h postadministration and cancerous areas could be easily localized. Biopsies were taken from the tumor sites as well as from normal bladder mucosa. Absolute uptake of the administered MAb expressed as percent administered dose/kg of tissue could be evaluated only in eight patients. Multiple specimen taken from various tumor sites in 75

However, previous attempts to incorporate docetaxel with an anthracycline in a dose-dense regimen have been unsuccessful. Therefore, new schedules containing both drugs should be explored. Forty-four patients with high-risk operable breast cancer entered this feasibility study. They were treated with three cycles of epirubicin 110 mg/m2 every 2 wk with G-CSF followed by three cycles of "intensified" CMF (840 mg/m2 cyclophosphamide; 57 mg/m2 methotrexate; 840 mg/m2 fluorouracil) every 2 wk with G-CSF followed 3 wk later by nine weekly cycles of 35 mg/m2 docetaxel (E-CMF-doc). Totally, 39 patients (89%) received all cycles of chemotherapy. The vast majority (92%) of cycles were administered at full dose. Therefore, dose intensity was sufficiently maintained for all drugs. Toxicity was generally mild to moderate. Most frequently recorded side effects apart from alopecia were neutropenia (54%) and nausea/vomiting (89%). Infection developed in nine patients. Two cases of febrile neutropenia were reported. The E-CMF-doc regimen, as used in this study, is feasible and well tolerated. Its impact on survival should be evaluated in phase III trials.

The purpose of this study was to evaluate alphaB-crystallin with respect to clinicopathological parameters and the outcome of patients with operable high-risk breast cancer. Methods: A total of 940 tumors were examined, derived from an equal number of patients who had participated in two randomized clinical trials (paclitaxel-containing regimen in 793 cases). Immunohistochemistry for ER, PgR, HER2, Ki67, CK5, CK14, CK17, EGFR, alphaB-crystallin, BRCA1 and p53 was performed. BRCA1 mutation data were available in 89 cases.

From October 2000 until October 2003 a total of 38 eligible patients (33 men and 5 women) entered the study. The large majority of them presented with a performance status of 0-1 and with clinical stage IV disease. Treatment consisted of three cycles of induction chemotherapy (IC) with paclitaxel 175 mg/m2 in a 3-h infusion on d 1, leucovorin (LV) 200 mg/m2 over 20 min immediately followed by FU 400 mg/m2 bolus and then 600 mg/m2 as a 24-h continuous infusion on d 1 and 2 and a cisplatin 75 mg/m2 over 1-h infusion on d 2 every 3 wk. This was then followed by radiation (70 Gy) and weekly cisplatin 40 mg/m2. After the completion of IC, 6/38 (16%) patients had CR. The CR rate was increased to 66% post-concomitant chemoradiotherapy (CCRT). Neutropenia (37.5%), pain (62%), nausea/vomiting (21%), and alopecia (79%) were the most frequent side effects during IC. The most pronounced toxicities during chemoradiotherapy were stomatitis (62.5%) and xerostomia (53%). Median time to progression was 11.0 mo and median survival 16.7 mo. One- and 2-yr survival rates were 73% and 38%, respectively. In conclusion, this novel induction regimen is active, is well tolerated, and can be successfully followed by CCRT with weekly cisplatin. CCRT should remain standard treatment for patients with LA-HNC. Novel induction combinations, such as that reported in the present study, should be evaluated in combination with CCRT only in the context of clinical trials.

Overexpression of the HER2 protooncogene occurs early in carcinogenesis and is maintained throughout the disease. HER2 gene amplification 1 and overexpression of the HER2 protein 2 occur in approximately 15%-25% of breast cancers and are known to be associated with aggressive tumor behavior and poor clinical prognosis. 1 The reduced progression-free and overall survival seen in patients with HER2 + breast cancer are clear evidence that early and accurate determination of HER2 status is of prognostic and therapeutic importance.

The survival of patients with prostate cancer who relapse after androgen ablation is limited and the therapeutic options are restricted. Twenty-nine patients with relapse after previous treatment were included in the study; however, 3 patients who refused to start treatment were not included in the analysis, leaving 26 eligible patients. The median age was 64 years (range 44 to 82), the World Health Organization performance status ranged from 1 to 3, and the mean prostate-specific antigen level was 103 ng/mL (range 1 to 620). The Gleason score ranged from 2 to 9. The patients received a total of 208 therapeutic cycles (mean 8, range 3 to 24). Every cycle consisted of oral estramustine 140 mg, 3 times a day continuously, and intravenous mitoxantrone 20 mg (total dose). The regimen was repeated every 2 weeks. Twenty-seven percent of patients with measurable soft-tissue disease demonstrated an objective response, which included one complete and six partial responses. Thirteen patients (50%) had a greater than 50% reduction in serum prostate-specific antigen level. The median duration of response was 9.2 months, and the median survival for all patients was 15 months. The most common side effects were neutropenia and thrombocytopenia. The combination of estramustine and mitoxantrone is safe, well tolerated, and relatively active in patients with hormone-refractory prostate cancer. More patients are needed to partake in Phase III studies to establish the survival benefit that this combination may offer.

Its combination with estramustine phosphate (EMP) has shown promising results in AIPC but the toxicity remains considerable. In an effort to minimize toxicity, we designed an every-2-week docetaxel administration regimen with a 3-day low-dose EMP regimen. Patients with bone metastases also received zoledronic acid. A total of 54 patients with AIPC received docetaxel at 45 mg/m2 and EMP (140 mg orally every 8 hours for nine doses) every 2 weeks. Zoledronic acid was administered at 4 mg every 28 days. Of the 49 assessable patients, 22 (45%, 95% confidence interval [CI] 31% to 60%) had a prostate-specific antigen response. Of 24 patients with measurable disease, 9 (38%, 95% CI 19% to 59%) had a response to therapy (one complete response and eight partial responses). The median time to progression was 4.4 months (95% CI 2.7 to 6), and overall survival was 13.3 months (95% CI 9 to 17.6). Toxicity was mild, with only 5 cases of grade 3 or 4 toxicity. The pain score improved by 1 point in 21 (54%) of 39 symptomatic patients, and 14 (40%) of 38 patients who used analgesics discontinued analgesic consumption by the end of treatment. The combination of an every-2-week regimen of docetaxel, EMP, and zoledronic acid is an effective, well-tolerated regimen that results in symptomatic improvement in a significant proportion of patients with AIPC.

Fifty-two patients with hormone-refractory prostate cancer were included in the study. Median age was 70 years (range, 49 to 100 years), World Health Organization performance status ranged from 0 to 2. The treatment schedule consisted of estramustine capsules (140 mg 3 times daily on days 1 to 3 and days 8 to 10 per os), intravenous mitoxantrone (12 mg/m2 on day 2), and intravenous vinorelbine (25 mg/m2 on day 2 and day 9), given in a 3-week cycle. Thirty-one percent of patients with measurable soft-tissue disease demonstrated an objective response, which included six complete and ten partial responses in all involved organs (bone responses not included). Twenty-nine patients (56%) had a greater than 50% reduction in serum prostate-specific antigen level. The median duration of response was 6.9 months, and the median survival for all patients was 14.5 months. The combination of estramustine, vinorelbine, and mitoxantrone is safe, well tolerated, and relatively active in patients with hormone-refractory prostate cancer.

Twenty-nine patients with relapse after previous treatment were included in the study; however, 3 patients who refused to start treatment were not included in the analysis, leaving 26 eligible patients. The median age was 64 years (range 44 to 82), the World Health Organization performance status ranged from 1 to 3, and the mean prostate-specific antigen level was 103 ng/mL (range 1 to 620). The Gleason score ranged from 2 to 9. The patients received a total of 208 therapeutic cycles (mean 8, range 3 to 24). Every cycle consisted of oral estramustine 140 mg, 3 times a day continuously, and intravenous mitoxantrone 20 mg (total dose). The regimen was repeated every 2 weeks. Twenty-seven percent of patients with measurable soft-tissue disease demonstrated an objective response, which included one complete and six partial responses. Thirteen patients (50%) had a greater than 50% reduction in serum prostate-specific antigen level. The median duration of response was 9.2 months, and the median survival for all patients was 15 months. The most common side effects were neutropenia and thrombocytopenia. The combination of estramustine and mitoxantrone is safe, well tolerated, and relatively active in patients with hormone-refractory prostate cancer. More patients are needed to partake in Phase III studies to establish the survival benefit that this combination may offer.

Docetaxel is an effective agent for the treatment of androgen-independent prostate cancer (AIPC).... more Docetaxel is an effective agent for the treatment of androgen-independent prostate cancer (AIPC). Its combination with estramustine phosphate (EMP) has shown promising results in AIPC but the toxicity remains considerable. In an effort to minimize toxicity, we designed an every-2-week docetaxel administration regimen with a 3-day low-dose EMP regimen. Patients with bone metastases also received zoledronic acid. A total of 54 patients with AIPC received docetaxel at 45 mg/m2 and EMP (140 mg orally every 8 hours for nine doses) every 2 weeks. Zoledronic acid was administered at 4 mg every 28 days. Of the 49 assessable patients, 22 (45%, 95% confidence interval [CI] 31% to 60%) had a prostate-specific antigen response. Of 24 patients with measurable disease, 9 (38%, 95% CI 19% to 59%) had a response to therapy (one complete response and eight partial responses). The median time to progression was 4.4 months (95% CI 2.7 to 6), and overall survival was 13.3 months (95% CI 9 to 17.6). Toxicity was mild, with only 5 cases of grade 3 or 4 toxicity. The pain score improved by 1 point in 21 (54%) of 39 symptomatic patients, and 14 (40%) of 38 patients who used analgesics discontinued analgesic consumption by the end of treatment. The combination of an every-2-week regimen of docetaxel, EMP, and zoledronic acid is an effective, well-tolerated regimen that results in symptomatic improvement in a significant proportion of patients with AIPC.

Fifty-two patients with hormone-refractory prostate cancer were included in the study. Median age was 70 years (range, 49 to 100 years), World Health Organization performance status ranged from 0 to 2. The treatment schedule consisted of estramustine capsules (140 mg 3 times daily on days 1 to 3 and days 8 to 10 per os), intravenous mitoxantrone (12 mg/m2 on day 2), and intravenous vinorelbine (25 mg/m2 on day 2 and day 9), given in a 3-week cycle. Thirty-one percent of patients with measurable soft-tissue disease demonstrated an objective response, which included six complete and ten partial responses in all involved organs (bone responses not included). Twenty-nine patients (56%) had a greater than 50% reduction in serum prostate-specific antigen level. The median duration of response was 6.9 months, and the median survival for all patients was 14.5 months. The combination of estramustine, vinorelbine, and mitoxantrone is safe, well tolerated, and relatively active in patients with hormone-refractory prostate cancer.
