Conditions

Bony Metastases From Castrate Refractory Prostate Cancer

Brief summary

To describe the changes seen on bone scan and correlate them with changes in relative chemical biomarkers, patient's functional status and level of pain.

Interventions

Previously known as Alpharadin, Radium-223 dichloride is a calcium-mimetic, alpha emitting radiopharmaceutical, which introduces double-stranded DNA breaks in metastatic cancer cells.

Design outcomes

Primary

MeasureTime frameDescription
Change in number of osteoblastic bone lesionsPretreatment (about 30 days before treatment) and post treatment (about 4 weeks after treatment)number of lesions specified before and after the treatment with a bone scan

Secondary

MeasureTime frameDescription
Hemoglobin levelpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsThe normal level for males is 14 to 18 g/dl
functional status as indicated by score on the Eastern Cooperative Oncology Group (ECOG) performance scalePretreatment (about 1 to 3 days before each treatment) for a total of 6 treatmentsThe ECOG scale describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.). The possible scores on the scale are 0 to 5, with 0 being the best outcome and 5 being the worst outcome, details of each score are listed below. Grade 0 = Fully active, able to carry on all pre-disease performance without restriction Grade 1 = Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work Grade 2 = Ambulatory and capable of all selfcare but unable to carry out any work activities; up and about more than 50% of waking hours Grade 3 = Capable of only limited selfcare; confined to bed or chair more than 50% of waking hours Grade 4 = Completely disabled; cannot carry on any selfcare; totally confined to bed or chair Grade 5 = Dead
pain level as assessed by numeric rating scorePretreatment (about 1 to 3 days before each treatment) for a total of 6 treatmentsAs assessed using numeric rating score from 1-10 with 10 being the highest level of pain
(PSA) prostate specific antigen levelpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsnormal level should be 4.0 ng/mL. value is measured after each dose
(ALP) alkaline phosphatase levelpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsThe normal value for alkaline phosphatase is 53 to 128 U/L.
Neutrophil countpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsThe normal range for neutrophils is 2.5-7.5 x 10 9 /L
Creatinine levelpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsNormal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dL)
white blood cell countpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsThe typical white blood cell count varies from 4,000 to 10,000 cells per mm3.
Platelet levelpretreatment (about 1 to 7 days before each treatment) for a total of 6 treatmentsA normal platelet count ranges from 150,000 to 450,000 platelets
