Strontium Compared With Radiation Therapy in Treating Patients With Hormone-Refractory Prostate Cancer With Painful Bone Metastases

2014-08-27 03:59:08 | BioPortfolio

Summary

RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. This may be an effective treatment for prostate cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of strontium or radiation therapy in treating patients with prostate cancer that is refractory to hormone therapy who have painful bone metastases.

Description

OBJECTIVES: I. Compare, in a randomized Phase III setting, the subjective response rate, time to progression, and survival of patients with hormone-refractory prostate cancer with painful osseous metastases treated with either strontium-89 or palliative local radiotherapy. II. Compare the quality of life achieved on these two regimens. III. Determine the toxicity and morbidity of treatment on these two regimens. IV. Compare the cost effectiveness of these two regimens.

OUTLINE: Randomized study. Arm I: Radioisotope therapy. Strontium-89 chloride, Strontium-89. Arm II: Radiotherapy. Involved-field irradiation (equipment unspecified).

PROJECTED ACCRUAL: 200 patients will be entered over 2 years.

Docetaxel and Prednisolone With or Without Zoledronic Acid and/or Strontium Chloride Sr 89 in Treating Patients With Prostate Cancer Metastatic to Bone That Has Not Responded to Hormone Therapy

RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisolone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from di...

Chemotherapy With or Without Strontium-89 in Treating Patients With Prostate Cancer

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radioactive substances such as strontium-89 may relieve bone pain as...

Hormone Ablation Therapy, Doxorubicin, and Zoledronate With or Without Strontium 89 in Treating Patients With Androgen-Dependent Prostate Cancer and Bone Metastases

RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Drugs such as goserelin and leuprolide may fight prostate cancer by stopping the adrenal glands from producing andro...

Zoledronate, Vitamin D, and Calcium With or Without Strontium 89 or Samarium 153 in Preventing or Delaying Bone Problems in Patients With Bone Metastases From Prostate Cancer, Lung Cancer, or Breast Cancer

RATIONALE: Zoledronate, vitamin D and calcium may prevent or delay bone pain and other symptoms caused by bone metastases. It is not yet known whether giving zoledronate together with vita...

A Dose-response Study With Strontium Malonate in Postmenopausal Women

The primary objective of the study is to compare dose-response effect of three dose levels of strontium malonate to placebo on bone resorption quantified by S-CTX-1 following 12 weeks of ...

Feasibility, safety, and efficacy of aerobic training in pretreated patients with metastatic breast cancer: A randomized controlled trial.

The investigation of exercise training in metastatic breast cancer has received minimal attention. This study determined the feasibility and safety of aerobic training in metastatic breast cancer.

Histopathological evaluation of the effect of locally administered strontium on healing time in mandibular fractures: An experimental study.

Mandibular fractures are the most common facial fractures. They can be treated by conservative techniques or by surgery. The authors hypothesized that the application of a single local dose of stronti...

Metastatic gastric cancer: Does the site of metastasis make a difference?

Metastatic gastric cancer has a poor prognosis. We aim to study how clinical features and prognosis differs between different metastatic sites, and to identify prognostic factors for overall survival.

Discordancy and changes in the pattern of programmed death ligand 1 expression before and after platinum-based chemotherapy in metastatic gastric cancer.

Our goal was to evaluate changes in PD-L1 expression in primary tumours of metastatic gastric cancer before and after chemotherapy.

Medical and Biotech [MESH] Definitions

Stable strontium atoms that have the same atomic number as the element strontium, but differ in the atomic weight. Sr-84, 86, 87, and 88 are the stable strontium isotopes.

Unstable isotopes of strontium that decay or disintegrate spontaneously emitting radiation. Sr 80-83, 85, and 89-95 are radioactive strontium isotopes.

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

Mucocellular carcinoma of the ovary, usually metastatic from the gastrointestinal tract, characterized by areas of mucoid degeneration and the presence of signet-ring-like cells. It accounts for 30%-40% of metastatic cancers to the ovaries and possibly 1%-2% of all malignant ovarian tumors. The lesions may not be discovered until the primary disease is advanced, and most patients die of their disease within a year. In some cases, a primary tumor is not found.
