RESUMO

A 61-year-old woman with BRCA2 pathogenic variant had been treated for 20 years and showed dynamic changes in the genomic profile of her metachronous bilateral breast cancer and metastases. She underwent right breast conservation surgery at age 42-Genome 1, lung metastasis and left axillary lymph node metastasis at age 51, partial excision under local anesthesia for left breast cancer at age 53-Genome 2, left axillary lymph node dissection was added 6 month later-Genome 3. Then, olaparib was administered, and subsequently, left mastectomy was performed for the recurrence of left breast cancer at age 59-Genome 4. Genomic profile of the tumor was analyzed at four points (Genome 1-3 were analyzed by in house breast cancer panel, and Genome 4 was analyzed by Foundation One CDx). Two interesting findings emerged from these analyses. First, the genomic profile revealed that the left axillary lymph node metastasis, considered histologically from right breast cancer, was a metastasis from the left breast cancer. The second finding is that as the disease progressed, mutation profile became more diverse. The profile of the left breast cancer removed after olaparib and other treatments showed reversion mutation of BRCA2 and was diagnosed as tumor mutation burden high. Subsequent response to pembrolizumab was favorable.

RESUMO

Docetaxel (DTX) is a key drug used in perioperative chemotherapy for breast cancer. Edema is a known adverse effect of DTX, but its effect on health-related QOL (HRQOL) is unclear. In this study, we evaluated the effects of edema caused by administration of DTX on HRQOL in patients with early-stage breast cancer. We prospectively investigated patients diagnosed with early-stage breast cancer (stage I-III) who received 4 cycles of DTX as preoperative or postoperative chemotherapy between September 2021 and December 2022 at Yamanashi Prefectural Central Hospital. The circumference of each extremity was measured at each administration of DTX, and limb edema was evaluated by Common Terminology Criteria for Adverse Events version 5.0. HRQOL was evaluated using SF-12 version 2, which has a range of 0-100 (national standard, 50), and compared between the presence and absence of grade 2 or higher edema and between before and after administration of DTX. Twenty patients met the eligibility criteria and were included in the study. There was no difference in the HRQOL score according to whether grade 2 limb edema was present. The median HRQOL summary scores before and after administration of DTX were 51.1 and 50.8 (p=0.763), respectively, for mental health, 52.6 and 49.4 (p=0.005) for physical health, and 38.9 and 37.5 (p=1.000) for role/social health. We found no direct effect of DTX-induced limb edema on HRQOL in patients with early-stage breast cancer. However, HRQOL summary scores indicated that administration of DTX reduced physical health in these patients.
