A multicenter survey of temporal changes in chemotherapy-induced hair loss in breast cancer patients.

ABSTRACT: PURPOSE:Many breast cancer patients suffer from chemotherapy-induced hair loss. Accurate information about temporal changes in chemotherapy-induced hair loss is important for supporting patients scheduled to receive chemotherapy, because it helps them to prepare. However, accurate information, on issues such as the frequency of hair loss after chemotherapy, when regrowth starts, the condition of regrown hair, and the frequency of incomplete hair regrowth, is lacking. This study aimed to clarify the long-term temporal changes in chemotherapy-induced hair loss using patient-reported outcomes for chemotherapy-induced hair loss. METHODS:We conducted a multicenter, cross-sectional questionnaire survey. Disease-free patients who had completed adjuvant chemotherapy consisting of anthracycline and/or taxanes for breast cancer within the prior 5 years were enrolled from 47 hospitals and clinics in Japan. Descriptive statistics were obtained in this study. The study is reported according to the STROBE criteria. RESULTS:The response rate was 81.5% (1511/1853), yielding 1478 questionnaires. Hair loss occurred in 99.9% of patients. The mean time from chemotherapy until hair loss was 18.0 days. Regrowth of scalp hair occurred in 98% of patients. The mean time from the completion of chemotherapy to the beginning of regrowth was 3.3 months. Two years after chemotherapy completion, the scalp-hair recovery rate was <30% in approximately 4% of patients, and this rate showed no improvement 5 years after chemotherapy. Eighty-four percent of the patients initially used wigs, decreasing to 47% by 1 year after chemotherapy and 15.2% after 2 years. The mean period of wig use was 12.5 months. However, a few patients were still using wigs 5 years after completing chemotherapy. CONCLUSIONS:Our survey focused on chemotherapy-induced hair loss in breast cancer patients. We believe these results to be useful for patients scheduled to receive chemotherapy.

Project description:BACKGROUND:Hair loss is one of the most common side effects of chemotherapy, and can cause persistent negative emotions, further affecting therapeutic effects and reducing the quality of life. However, there are no clinically safe and effective methods to solve the problem at present. Our previous clinical and animal studies showed that a medicinal and edible decoction, YH0618, could significantly promote hair growth in cancer patients after chemotherapy, without interfering with the anti-tumor effects of chemotherapy. Besides, the theory of Chinese Medicine believes that the "Essence of the kidney is reflected on the hair". Therefore, this study will further explore the efficacy of YH0618 granule on chemotherapy-induced hair loss in patients with breast cancer by a randomized, double-blind, multi-center clinical trial and elucidate the potential mechanism from the aspect of kidney deficiency or renal dysfunction. METHODS/DESIGN:Eligible breast cancer patients who will start chemotherapy will be randomly divided into group A (YH0618 granule) and group B (placebo). The chemotherapeutic agents contain taxanes or/and anthracyclines, and the chemotherapy regimen will be for at least six cycles with a cycle every 3 weeks. Subjects assigned to group A will receive YH0618 granules twice a day (6?g each time), 6?days a week, mixed with 300?ml warm water from the first to the fourth chemotherapy cycle. Subjects in group B will receive the placebo granule in the same manner. The primary outcome is the time point of occurrence of hair loss reaching grade II as assessed by the WHO Toxicity Grading Scale, and objective indices of hair quality and hair-follicle growth recorded by a hair and scalp detector before the fifth chemotherapy cycle. Secondary outcomes include changes of facial color and thumbnail color, grading of thumbnails ridging, assessment of quality life, level of fatigue, routine blood test results, hepatic and renal function, and certain medical indicators which can reflect kidney deficiency in Chinese Medicine. DISCUSSION:This research is of great significance for the treatment of cancer and improving the quality of life of cancer patients. The study may provide the most direct evidence for meeting clinical needs and lay a solid scientific foundation for later product development.

Project description:Inflammation has been associated with fatigue during and after various types of breast cancer treatments. We examined whether prior chemotherapy was associated with DNA methylation patterns that could explain persisting inflammation and/or fatigue in women treated for breast cancer. Prior to breast radiation therapy, DNA was extracted from peripheral blood mononuclear cells (PBMCs) of 61 Stage 0-IIIA breast cancer patients who had received partial mastectomy with or without chemotherapy. DNA methylation was assessed at >485,000 CpG sites across the genome along with fatigue and plasma inflammatory markers previously associated with fatigue. Compared to non-chemotherapy-treated, women who had received chemotherapy exhibited significantly decreased methylation at eight CpG sites (p<1.03×10(-7)) including four in exon 11 of transmembrane protein 49 (TMEM49), which demonstrated the largest decreases in methylation. Lower methylation at each identified CpG site was associated with increased plasma soluble tumor necrosis factor receptor 2 (sTNFR2) and interleukin (IL)-6 and mediated the relationship between chemotherapy and increases in these inflammatory biomarkers adjusting for multiple clinical and treatment characteristics. sTNFR2, but not CpG methylation status, was correlated with fatigue. Six months after breast radiation therapy, DNA methylation, inflammatory biomarkers and fatigue assessments were repeated in a subset of subjects (N=39). Reduced methylation in 4 of the 8 identified CpG sites was still observed in chemotherapy versus non-chemotherapy-treated patients, albeit with some decay indicating the dynamic and potentially reversible nature of the changes. Reduced methylation in these 4 CpG sites also continued to correlate with either increased sTNFR2 or IL-6, but not fatigue. In conclusion, prior chemotherapy treatment was associated with decreased methylation of CpG sites in DNA from PBMCs of breast cancer patients, which correlated with increased inflammatory markers prior to and 6months after radiation therapy. Persisting epigenetic changes secondary to chemotherapy may be one factor that contributes to inflammation and its consequences including cancer-related fatigue in vulnerable breast cancer patients.
