Leuplin SR 11.25 mg Injection Kit Specified Drug-use Survey: QOL Survey in Premenopausal Breast Cancer Patients

Study Overview
=================
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of Life Questionnaire for Cancer Patients Treated With Anticancer Drugs (QOL-ACD) Total and Subscale Score at Baseline | QOL-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. Less total/subscale scores reflect greater symptom severity and symptom impact on health-related QOL. | Baseline |

| --- | --- | --- |
| Percentage of Participants With Reduction in Frequency of Medical Visits Due to Change in Medicinal Agents | The question was with regard to the assessment of convenience associated with the changes in agents, Did the change in agents reduce the frequency of your medical visits? and the answers were categorized as very much reduced, somewhat reduced, unchanged. Change in medicinal agents means participants with a historical diagnosis of premenopausal breast cancer who switched to leuprorelin acetate sustained-release 11.25 mg injection kit from a 4-week adjuvant therapy with a LH-RHa 1 month depot preparation as part of daily medical practice. | Week 48 | 
| Percentage of Participants Who Felt Relief From Physical and Emotional Burden | The question was with regard to the assessment of convenience associated with the changes in agents, The change in agents reduced the frequency of injections by one third; for this reason, did you feel relief from physical and emotional burden? and the answers were categorized as felt extreme relief, felt slight relief, no feeling either way, felt little relief, felt no relief. | Week 48 | 
| Percentage of Participants With Relief From Financial Burden Due to the Change in Medicinal Agents | The question was with regard to the assessment of convenience associated with the changes in agents, Did you feel relief from financial burden (example, 3 months' drug costs and transportation fee) due to the change in agents? and the answers were categorized as felt extreme relief, felt slight relief, no feeling either way, felt little relief, felt no relief. The sum of all the categories is not 100% because of rounding error. | Week 48 | 
| Percentage of Participants Who Worried About the Effect of the Medicinal Agent | The question was with regard to the assessment of convenience associated with the changes in agents, The change in agents reduced the frequency of injections by one third; for this reason, did you worry about the effect? and the options of the answers were not at all worried, not too worried, no thought either way, somewhat worried, and very worried. | Week 48 | 
| Percentage of Participants With Change in Adverse Drug Reactions Due to the Change in Medicinal Agents | The question was with regard to the assessment of convenience associated with the changes in agents, Was there a change in adverse drug reactions (e.g., menopausal-like symptoms such as hot flushes, injection-site abnormalities) due to the change in agents? and the options of the answers were events became much less severe, events became less severe, whether or not the events became severe cannot be determined, events became slightly more severe, and events became very severe. | Week 48 | 
| Percentage of Participants With Change in Pain at the Time of Injection Due to the Change in Medicinal Agents | The question was with regard to the assessment of convenience associated with the changes in agents, Was there a change in pain at the time of injection due to the change in agents? and the options of the answers were significantly relieved, slightly relieved, whether or not the pain worsened or was relieved cannot be determined, worsened slightly, and worsened significantly. | Week 48 |

| 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. | Baseline up to Week 48 | 
| Number of Participants Reporting One or More Serious Adverse Drug Reactions | Serious 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. | Baseline up to Week 48 |
