Assessing Clinical Outcomes in Colorectal Cancer with Assays for Invasive Circulating Tumor Cells.

Colorectal carcinoma (CRC) is the second leading cause of cancer-related mortality. The goals of this study are to evaluate the association between levels of invasive circulating tumor cells (iCTCs) with CRC outcomes and to explore the molecular characteristics of iCTCs. Peripheral blood from 93 patients with Stage I⁻IV CRC was obtained and assessed for the detection and characterization of iCTCs using a functional collagen-based adhesion matrix (CAM) invasion assay.

Multicenter, randomized phase II trial of bevacizumab plus folinic acid, fluorouracil, gemcitabine (FFG) versus bevacizumab plus folinic acid, fluorouracil, oxaliplatin (FOLFOX4) as first-line therapy for patients with advanced colorectal cancer.

Purpose: To assess safety and efficacy of folinic acid, 5-fluorouracil, gemcitabine (FFG) and folinic acid, fluorouracil, oxaliplatin (FOLFOX4) regimens with added bevacizumab as first-line treatment in patients with advanced colorectal cancer (CRC).

Patients And Methods: Patients with Stage III unresectable or Stage IV adenocarcinoma of the colon or rectum were randomly assigned to either FFG weekly for 6 weeks of an 8-week cycle or FOLFOX4 every 2 weeks. After FDA approval, bevacizumab 5 mg/kg was added every 2 weeks.

Abdominal aortitis after use of granulocyte colony-stimulating factor.

Granulocyte colony-stimulating factor (G-CSF) is a recombinant human glycoprotein that promotes proliferation and differentiation of granulocytic-committed progenitors. It is commonly used to treat neutropenia and is generally well tolerated. Occurrences of rare but serious adverse events in association with the use of G-CSF have been described.

Isolation of circulating epithelial and tumor progenitor cells with an invasive phenotype from breast cancer patients.

Recent research advances show that tumor cell intravasation (entry into the circulation) and metastasis occur very early in breast cancer progression. Clinical studies also illustrate the potential importance of detection of circulating tumor cells (CTCs) in outcomes of patients with metastatic breast cancer. Whether these cells exhibit the invasiveness and express tumor stem or progenitor markers, hallmark of the metastatic phenotype, is less well characterized.

A phase II trial of carboplatin and gemcitabine with exisulind (IND #65,056) in patients with advanced non-small cell lung cancer: an Eastern Cooperative Oncology Group study (E1501).

Background: Carboplatin and gemcitabine are one standard regimen for patients with advanced non-small cell lung cancer (NSCLC). The oral proapoptotic agent exisulind is a cyclic guanosine monophosphate phosphodiesterase that increases apoptosis in vitro. We performed a phase II trial of carboplatin and gemcitabine with exisulind in patients with advanced NSCLC.

A phase I/randomized phase II, non-comparative, multicenter, open label trial of CP-547,632 in combination with paclitaxel and carboplatin or paclitaxel and carboplatin alone as first-line treatment for advanced non-small cell lung cancer (NSCLC).

Purpose: To evaluate the toxicity profile and pharmacological properties of oral CP-547,632 alone and in combination with paclitaxel and carboplatin administered every 3 weeks, and to assess efficacy as measured by the objective response and progressive disease rates of oral CP-547,632 administered in combination with paclitaxel and carboplatin.

Patients And Methods: Patients with stage IIIB/IV or recurrent non-small cell lung cancer receiving first-line chemotherapy were treated with oral daily CP-547,632 in combination with paclitaxel 225 mg/m(2) and carboplatin AUC = 6 every 3 weeks. Pharmacokinetics parameters for CP-547,632 and paclitaxel were determined independently and during co-administration.

Implication of delayed TNF-alpha exposure on dendritic cell maturation and expansion from cryopreserved cord blood CD34+ hematopoietic progenitors.

Most currently used systems for dendritic cell (DC) production from progenitors entail tumor necrosis factor alpha (TNF-alpha) at the onset of cell culture, based on the notion that TNF-alpha might be required in the early stages of DC development. To optimize conditions for DC expansion from cryopreserved cord blood (CB) CD34+ hematopoietic progenitors, we took a dynamic approach to define the timing of TNF-alpha exposure to the culture. We cultured cord blood CD34+ cells in RPMI-1640 with 10% human AB plasma, stem cell factor (days 1-6), granulocyte-macrophage colony-stimulating factor (days 1-18), interleukin-4 (days 6-18) and varying schedules of TNF-alpha (0-144 h after thawing).

Oral capecitabine vs intravenous 5-fluorouracil and leucovorin: integrated efficacy data and novel analyses from two large, randomised, phase III trials.

This study evaluates the efficacy of capecitabine using data from a large, well-characterised population of patients with metastatic colorectal cancer (mCRC) treated in two identically designed phase III studies. A total of 1207 patients with previously untreated mCRC were randomised to either oral capecitabine (1250 mg m(-2) twice daily, days 1-14 every 21 days; n=603) or intravenous (i.v.

Phase I chemotherapy study of biochemical modulation of folinic acid and fluorouracil by gemcitabine in patients with solid tumor malignancies.

Purpose: This phase I biochemical modulation study evaluated the maximum-tolerated dose (MTD), toxicity, and effectiveness of the combination of folinic acid (FA)/fluorouracil (5-FU) followed by escalated dose levels of gemcitabine (FFG) in patients with advanced solid tumors.

Patients And Methods: Patients were refractory to primary treatment and/or without effective treatment options. Twenty-eight patients received an intravenous (IV) infusion of FA 100 mg/m(2) over 1 hour and a 5-FU 450 mg/m(2) IV bolus in the middle of the FA infusion.

Therapy for patients with high grade astrocytoma using intraarterial chemotherapy and radiation therapy.

Background: High grade astrocytomas account for approximately 40% of all primary brain tumors. The median survival is approximately 8-10 months for patients with glioblastoma multiforme and 36 months for patients with anaplastic astrocytoma. The results of systemic chemotherapy in the treatment of brain tumors have been reported to be less than satisfactory, mainly because of the blood-brain barrier impermeability for chemotherapeutic drugs.

Actual 5-year survival of patients with stage IIIB breast carcinoma: phase II trial of methotrexate, vinblastine, adriamycin, cisplatin, and folinic acid.

Patients with stage IIIB breast carcinoma represent only a small proportion of women with breast cancer in western countries but may constitute up to 50% of cases in underdeveloped countries. The prognosis remains poor despite aggressive treatment. Nineteen patients (11 with inflammatory breast carcinoma) received at least three courses of neoadjuvant chemotherapy of methotrexate, vinblastine, adriamycin, cisplatin, and folinic acid (MVAC/FA) followed by mastectomy.

A Comparison of Oral Ondansetron and Intravenous Granisetron for the Prevention of Nausea and Emesis Associated with Cisplatin-Based Chemotherapy.

PURPOSE: To compare the efficacy and safety of oral ondansetron with i.v. granisetron each given as a single dose prior to administration of highly emetogenic cisplatin chemotherapy.

Toxicities related to intraarterial infusion of cisplatin and etoposide in patients with brain tumors.

Chemotherapy for malignant brain tumors has a limited efficacy largely due to restricted blood-brain barrier permeability for chemotherapeutic drugs. Intraarterial chemotherapy (IAC) has the advantage of increased uptake during the first passage of the drugs through tumor capillaries. Initial IAC trials had less than satisfactory results due to unacceptable toxicities.

Treatment of metastatic bone pain with tin-117m Stannic diethylenetriaminepentaacetic acid: a phase I/II clinical study.

The physical characteristics of Sn-117m combined with the biodistribution of the compound tin-117m (Stannic, 4+) diethylenetriaminepentaacetic acid (Sn-117m DTPA) suggest that it should be an excellent agent for the palliation of pain from bony metastases. Prior work has established the dosimetry and the safety for the material in human beings. The presence of low-energy conversion electrons should result in the relative sparing of the bone marrow while delivering a high radiation dose to sites of bony metastatic disease.

Efficacy and tolerability of oral ondansetron versus prochlorperazine in the prevention of emesis associated with cyclophosphamide-based chemotherapy and maintenance of health-related quality of life.

This study compared the efficacy and tolerability of oral ondansetron (8 mg twice daily [BID] for up to 3 days) with those of phenothiazine prochlorperazine (10 mg BID for up to 3 days) in 133 cancer patients receiving cyclophosphamide-based chemotherapy. In addition, the study evaluated the impact of these treatments on patients' health-related quality of life, measured with both the Functional Living Index-Cancer and the Functional Living Index-Emesis questionnaires. The first dose of study drug was administered 30 minutes before initiation of chemotherapy.

Preclinical and clinical evaluation of 5-fluorouracil biochemical modulation with folinic acid and hydroxyurea for patients with colorectal carcinoma.

Background: Approximately 140,000 new cases of colorectal carcinoma will be diagnosed in 1995 in the United States, and more than one-third of these patients will die from progressive disease. Despite the modest improvement in response rate with chemotherapy, little improvement in patient survival has been noted. Consequently, the evaluation of new agents, modalities, and combinations is needed.

Oral ondansetron for the control of cisplatin-induced delayed emesis: a large, multicenter, double-blind, randomized comparative trial of ondansetron versus placebo.

Purpose: To investigate the efficacy and safety of oral ondansetron in the control of cisplatin-induced delayed emesis in patients who do not require rescue antiemetic therapy for acute emesis.

Patients And Methods: Five hundred thirty-eight chemotherapy-naive patients who received cisplatin chemotherapy (> or = 70 mg/m2), and who were not rescued for acute emesis, were eligible to be randomized to receive one of the three oral regimens to control delayed emesis. Group I received placebo on days 2 to 6; group II received ondansetron 8 mg twice daily on days 2 and 3 and placebo on days 4 to 6; group III received ondansetron 8 mg twice daily on days 2 to 6.

Treatment of cancer-associated hypercalcemia. Double-blind comparison of rapid and slow intravenous infusion regimens of pamidronate disodium and saline alone.

Background: We assessed the effects of 60-mg single doses of pamidronate disodium compared with saline alone in the treatment of cancer-associated hypercalcemia.

Methods: After pretreatment hydration, patients with corrected serum calcium concentrations of 3.0 mmol/L (12 mg/dL) or greater secondary to cancer were randomized to double-blind treatment with a single infusion of pamidronate disodium, 60 mg, over either 4 or 24 hours or continued infusions of 0.

Positron emission tomography study of human prostatic adenocarcinoma using carbon-11 putrescine.

To evaluate [1-11C]putrescine ([11C]PUT) as a potential tracer for imaging and characterization of human prostatic adenocarcinoma, positron emission tomography (PET) was performed in eight patients and three normal controls. In addition, four of the patients and the three normal controls also had a prostate scan with 2-deoxy-2-[18F]fluoro-D-glucose (18FDG). Three of the patients had undergone resection of the prostate tumor and all of the patients except for one had bone metastasis.

Alpha interferon, leucovorin, and 5-fluorouracil (ALF) in advanced cancer: results of a dose-finding study and evidence of activity in non-small cell lung cancer.

In a phase I trial, 17 patients were treated with 5-fluorouracil (5-FU) 500 mg/m2 and leucovorin (LV) 500 mg/m2 intravenously weekly for 6 weeks followed by 2 weeks' rest and interferon alfa-2b 1, 3, 5, 8, or 10 million units (MU) subcutaneously tiw with no rest period. The most common toxicities were fatigue (12), diarrhea (10), nausea/vomiting (7), and fever (7). The maximum tolerated interferon dose was 8 MU tiw.

Biodistribution of Sn-117m(4+)DTPA for palliative therapy of painful osseous metastases.

Tin-117 has certain physical characteristics (half-life of 13.6 days, low-energy-conversion electrons, gamma photon of 158.6 keV) that suggest that it may be a favorable agent for radionuclide therapy.

Stratified, randomized, double-blind comparison of intravenous ondansetron administered as a multiple-dose regimen versus two single-dose regimens in the prevention of cisplatin-induced nausea and vomiting.

Purpose: This study compares the efficacy and safety of two single-dose regimens with the approved three-dose regimen of ondansetron in the prevention of cisplatin-induced emesis.

Patients And Methods: This multicenter study was a stratified, randomized, double-blind, and parallel group design. Chemotherapy-naive inpatients were randomized to receive intravenous (IV) ondansetron (Zofran; Glaxo Inc, Research Triangle Park, NC) 0.

Intracarotid chemotherapy with etoposide and cisplatin for malignant brain tumors.

Chemotherapy for tumors of the central nervous system has a limited efficacy presumably because of restricted blood-brain barrier permeability. The advantage of regional intra-arterial administration of anticancer drugs is an increased uptake during the first passage of the drugs through tumor capillaries. Twenty patients with high-grade astrocytomas (HGA) and 28 patients with metastatic brain tumors (MBT) received intracarotid/intravertebral infusion of etoposide and cisplatin.

Randomized phase II evaluation of carboplatin and CHIP in advanced transitional cell carcinoma of the urothelium. The Eastern Cooperative Oncology Group.

A total of 83 patients with metastatic transitional cell carcinoma who had previously received no systemic therapy entered a randomized phase II evaluation of carboplatin and cis-dichloro-transdihydroxy-bis-isopropylamine platinum IV (CHIP), administered respectively at 400 and 270 mg./m.2 every 28 days.
