Brief summary

The purpose of this survey is to examine the effect on quality of life (QOL) improvement and convenience of switching to leuprorelin acetate 3 months depot 11.25 milligram (mg) injection kit (Leuplin SR 11.25 mg injection kit) from a 4-week adjuvant therapy with a luteinizing hormone-releasing hormone analog (LH-RHa) 1 month depot over 48 weeks in premenopausal breast cancer participants in daily medical practice. Influence of condition of estrogen receptor expression on the efficacy and safety of leuprorelin acetate SR 11.25 mg injection kit was also evaluated.

Detailed description

This survey was designed to examine the effect on QOL improvement and convenience of switching to leuprorelin acetate 3 month depot 11.25 mg injection kit (Leuplin SR 11.25 mg injection kit) from a 4-week adjuvant therapy with a LH-RHa 1 month depot over 48 weeks in premenopausal breast cancer participants in daily medical practice, as well as to evaluate the influence of condition of estrogen receptor expression on the efficacy and safety of leuprorelin acetate SR 11.25 mg injection kit . For adults, leuprorelin acetate SR 11.25 mg injection kit (Leuplin SR 11.25 mg Injection Kit) is usually administered subcutaneously once every 12 weeks. Prior to injection, the plunger rod of the syringe is pushed upward with the needle pointed upward, allowing the entire suspension fluid contained to be transferred to the powder. The powder is then fully suspended in the fluid while ensuring that bubbles are not generated.

For questionnaire item 19 (Did you feel inferior to your child when you interact with him/her? \[due to the impact of illness and treatment\]), item 20 (Did you worry about child rearing? \[due to the impact of illness and treatment\]), and item 21 (Do you worry about pregnancy or delivery? \[due to the impact of illness and treatment\]), the calculation was based on the score of each item. Each item was scored on a 5-point scale, where 1 was the worst response and 5 was the best.
Quality of Life Questionnaire for Cancer Patients Treated With Anticancer Drugs (QOL-ACD) Total and Subscale Score at BaselineBaselineQOL-ACD score is a score used for cancer participants treated with anti-cancer drug and is a 22-item self-reported instrument assessing differences in symptom severity and health-related QOL. It includes 4 subscale domains: Daily Activities, Physical Condition, Social Activities, Mental and Psychological Status. Total and subscale scores are calculated as sum of items within each subscale: Daily Activity (items 1-6), Physical Condition (7-11), Psychological Condition (12-16), Social Attitude (17-21) and total (1-22). Face scale: 5-point score for 1 item (22). Participants answer each question on a 5-point scale (1: not at all \[worst response\] to 5: very much \[best response\]). Score range for total score is 22 to 110 and subscale score range for daily activity is 6 to 30, and for physical condition, psychological condition, and social attitude is 5 to 25.

Number of Participants Reporting One or More Adverse Drug ReactionsBaseline up to Week 48Adverse drug reactions are defined as adverse events (AE) which are in the investigator's opinion of causal relationship to the study treatment. AE are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product reported from the first dose of study drug to the last dose of study drug.
Number of Participants Reporting One or More Serious Adverse Drug ReactionsBaseline up to Week 48Serious adverse drug reactions are defined as serious adverse events (SAE) which are in the investigator's opinion of causal relationship to the study treatment. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The event was occurred in breast cancer female.

QOL-ACD is a score used for cancer participants treated with anti-cancer drug and is a 22-item self-reported instrument assessing differences in symptom severity and health-related QOL. Participants answer each question on a 5-point scale (1: not at all \[worst response\] to 5: very much \[best response\]). Total score was calculated over score range 0-100 for item 1 to 18 as ((a sum of 18 items)/18-1)\*25). Score for physical condition and pain was calculated over score range 0-100 for item 1 to 6 as ((a sum of 6 items)/6-1)\*25)). Score for health-care and illness satisfaction was calculated over score range 0-100 for item 7 to 10 as ((a sum of 4 items)/4-1)\*25)), where less scores reflect greater symptom severity and symptom impact on health-related quality of life.

QOL-ACD-B is a part of QOL-ACD (using questionnaire items 1 to 18). For questionnaire item 19 (Did you feel inferior to your child when you interact with him/her? \[due to the impact of illness and treatment\]), item 20 (Did you worry about child rearing? \[due to the impact of illness and treatment\]), and item 21 (Do you worry about pregnancy or delivery? \[due to the impact of illness and treatment\]), the calculation was based on the score of each item. Each item was scored on a 5-point scale, where 1 was the worst response and 5 was the best.

Time frame: Week 12

Population: Efficacy assessment population where Week 12 assessment for each item were available. Efficacy assessment population included those participants who received at least one dose of study medication and had efficacy data available.

Number of Participants Reporting One or More Adverse Drug Reactions

Adverse drug reactions are defined as adverse events (AE) which are in the investigator's opinion of causal relationship to the study treatment. AE are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product reported from the first dose of study drug to the last dose of study drug.

Time frame: Baseline up to Week 48

Population: Safety analysis set was defined as participants who received at least one dose of study medication.
