Real Life Evaluation of Lupron in the Management of Prostate Cancer: A Canadian Post Marketing Observational Study

PFS defined as the time from patient recruitment to biochemical progression based on doubling of prostate specific antigen (PSA) velocity or PSA > 5.0, objective tumor progression (RECIST criteria), or death. The distribution of PFS was estimated using Kaplan-Meier methodology. The point estimate and standard error (SE) of the distribution are provided.

A second definition of PFS was used due to changes in the definition of biochemical progression: the time from patient recruitment to a change to an absolute value of PSA > 2 ng/mL on at least 2 consecutive tests, objective tumor progression (RECIST criteria), or death. The distribution of PFS was estimated using Kaplan-Meier methodology. The point estimate and standard error (SE) of the distribution are provided.

CRPC defined as PSA > 2 ng/mL on at least 2 consecutive tests.

CRPC defined as PSA > 2 ng/mL on at least 2 consecutive tests. The distribution of time to CRPC was estimated using Kaplan-Meier methodology. The point estimate and standard error of the distribution are provided.

Total serum testosterone was assessed at each study visit. The percentage of participants with total serum testosterone ≤ 0.7 nmol/L, > 0.7 to ≤ 1.7 nmol/L, and > 1.7 nmol/L are provided at each time point.

Total serum testosterone was assessed at each study visit.

Total serum testosterone was assessed at each study visit. The time to increased total serum testosterone over the castrate levels (>1.7 nmol/L) are provided. The distribution of time to increase in total serum testosterone levels was estimated using Kaplan-Meier methodology. The point estimate and standard error (SE) of the distribution are provided.

Serum PSA was assessed at each study visit. The percentage of participants with serum PSA < 1 ng/mL, 1 to < 5 ng/mL, 5 to < 10 ng/mL, and ≥10 ng/mL are provided at each time point.

The FACT-G questionnaire is used with patients of any tumor type to assess patient quality of life (QoL). FACT-G is a self-administered, 28-item questionnaire assessing physical, functional, social and emotional well-being, as well as patient satisfaction with treatment. All questions in the FACT-G use a 5-point rating scale (0 = Not at all; 1 = A little bit; 2 = Somewhat; 3 = Quite a bit; and 4 = Very much). The FACT-G total score is computed as the sum of the four subscale scores and has a possible range of 0-108. Higher scores indicate better QoL. Change in FACT-G was analyzed using repeated measures mixed effects general linear model (GLM). A positive change from baseline indicates improved QoL.

The FACT-P questionnaire is used with patients with prostate cancer to assess patient quality of life (QoL). FACT-P is a self-administered, 28-item questionnaire assessing physical, functional, social and emotional well-being, as well as patient satisfaction with treatment. All questions in the FACT-P use a 5-point rating scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; and 4 = very much). The FACT-P total score is computed as the sum of the four subscale scores and has a possible range of 0-108. Higher scores indicate better QoL. Change in FACT-P was analyzed using repeated measures mixed effects general linear model (GLM). A negative change from baseline indicates decreased QoL.

IIEF-5 is a 5-item, self-administered questionnaire assessing the presence and severity of erectile dysfunction. A score of 1 (very low) to 5 (very high) is awarded to each of the 5 questions. The IIEF-5 total score is a sum of the responses to the 5 items. Total scores range from 5 to 25, with higher scores indicating less dysfunction. Change in IIEF-5 was analyzed using repeated measures mixed effects general linear model (GLM). A negative change from baseline indicates an increase in dysfunction.

The Health Care Utilization and Health Economics Questionnaire is a descriptive, self-administered series of questions aimed at measuring the patient's health care utilization and economic impact of the disease. The questionnaire was used to assess since the last visit the frequency of physician visits; utilization of other health care professionals; visits to clinics, emergency rooms, and hospitalizations related to prostate cancer; use of prescription and non-prescription medications for the management of prostate cancer were determined; and out of pocket expenses for medications and health care.
