Elderly cancer patients would suffer cognitive impairment due to chemotherapy, and a series of neurocognitive symptoms, known as "chemobrain". Chinese acupuncture plus herbal decoctions is an emerging therapeutic option for chemotherapy induced cognitive impairment in elderly cancer patients, despite limited supporting evidence. By evaluating this novel Chinese medicine mode in elderly cancer patients at our institution, the investigators aim to contribute to the existing knowledge in this area while establishing a basis for further research. The investigators will perform a study of all cases of "chemobrain" related elderly cancer patients treated with Chinese acupuncture from 2023 to 2025. The investigators would enroll 168 elderly cancer patients with clinically confirmed chemobrain; those for Chinese acupuncture will be treated with electroacupuncture (2 sessions per week over 8 weeks) ; the others will be received conventional drug therapy, or palliative-intent therapy. The Montreal Cognitive Assessment (MoCA) will be served as the primary outcome. Digit span test will be the secondary outcome for attentional function and working memory. The quality of life and multiple functional assessments will also be evaluated.
Elderly cancer patients would suffer cognitive impairment due to chemotherapy, and a series of neurocognitive symptoms, known as "chemobrain". Chinese acupuncture plus herbal decoctions is an emerging therapeutic option for chemotherapy-induced cognitive impairment in elderly cancer patients, despite limited supporting evidence. By evaluating this novel Chinese medicine mode in elderly cancer patients at our institution, the investigators would like to contribute to the existing knowledge in this area while establishing a basis for further research. This randomized controlled trial would be conducted from Jan 2023 to December 2025 in clinics of Nanjing 1st Hospital, Nanjing, China. Potentially eligible patients will be recruited through clinical oncologists' referral from local hospital and advertisement. The study protocol should be approved by Institutional Review Board(IRB) of the Nanjing 1st Hospital. The investigators will enroll 168 elderly cancer patients with clinically confirmed chemobrain. Acupuncture intervention will be conducted for 2 sessions per week over 8 consecutive weeks. The determination of 8 weeks of the treatment duration will be based on the fact that the robust effects of acupuncture in cancer patients will be generally observed within 8 weeks of treatment. The primary outcome will be measured using the Montreal Cognitive Assessment(MoCA) which has been extensively used in the study of cognitive disorders. The forward and reverse digit span test would serve the secondary outcomes to detect attentional function and working memory. In addition, EORTCQLQ-C30 will be used to examine the quality of life of elderly cancer patients. Functional changes and side effects associated with therapies will be measured using the Functional Assessment of Cancer Therapy (FACT), Functional Assessment of Chronic Illness Therapy (FACIT), Functional Assessment of Anorexia/Cachexia Therapy (FAACT), Functional Assessment of Cancer Therapy-Taxane (FACT-Taxane), and Functional Assessment of Cancer Therapy-Biologic Response Modifier (FACT-BRM). These instruments have been widely used in elderly cancer patients. Most items of these functional assessments are 5-point Likert scale questions. Functional items which would be rated as "3" (quite a bit) or higher and incidences would be significantly different between the two groups in any assessment point will be extracted for statistical analysis.

Disposable acupuncture needles(0.30mm in diameter and 25-40mm in length) will be inserted at a depth of 10-30mm perpendicularly or obliquely into acupoints. Manual manipulation will be carried out for all acupoints to evoke needling sensation. Electrical stimulation was additionally delivered on the 6 pairs of the frontal acupoints. The output peak current and voltage of the machine would be 6V and 48mA, respectively, with constant wave at frequency of 2Hz and phase duration of 100µs for 30min. Electrical stimulation lasted 30min. The needles on body acupoints will be also retained for 30min. Acupuncture intervention will be conducted for 2 sessions per week over 8 consecutive weeks. The determination of 8 weeks of the treatment duration will be based on the fact that the robust effects of acupuncture in cancer patients will be generally observed within 8 weeks of treatment.
