Dear Editor,
We would like to submit the enclosed manuscript entitled “Quality of life and mood of older patients with acute myeloid leukemia (AML) receiving intensive and non-intensive chemotherapy” for possible publication in the LEUKEMIA.(介绍研究题目和目标杂志)

The contents of this manuscript will not be copyrighted, submitted, or published elsewhere, while acceptance by the LEUKEMIA is under consideration. All authors have read and approved the final submitted version; all individuals listed as authors were eligible for authorship.(介绍利益冲突)
Older adults (≥60 years of age) with acute myeloid leukemia (AML) have a relatively poor prognosis with a low chance for long-term disease-free survival. Currently, no consensus exists regarding the optimal initial treatment strategy for older patients with AML. The difficulties of AML and its treatment impact not only patients but also their caregivers. In the present article, we assessed: (i) over time the QOL, fatigue, and mood of older patients with AML receiving intensive and non-intensive chemotherapy anxiety and depression in adult AL patients and their FCs and (ii) the psychological distress experienced by caregivers of older patients with AML.(介绍研究背景和研究问题)
This study demonstrated that older patients with newly diagnosed AML receiving therapy report improvement in their QOL, fatigue, and anxiety symptoms over time. This suggests a clear benefit to therapy for this population in terms of patient-reported outcomes. Strategies to enhance patients’ understanding of their illness experience and their expected QOL trajectory may better inform their decision-making regarding the optimal treatment strategy for their disease.(介绍研究发现及临床启示)
We deeply appreciate your consideration of our manuscript. We look forward to receiving comments from the reviewers. If you have any queries, please do not hesitate to contact me at the address below. Thank you in advance.(礼貌性感谢和期待回复)
Best regards,(此处可用其他礼貌用语替代，诸如Yours sincerely等)
