Abstract

Introduction: HER2-positive breast cancer is associated with poor outcomes and higher mortality rates than other breast cancer subtypes. The advent of trastuzumab has significantly changed the natural history of HER2-positive breast cancer. However, it is not an affordable treatment option in sub-Saharan African countries. Because of the expense, most patients in our setting do not receive trastuzumab for the optimal control of their disease. Additionally, there is a lack of comprehensive data about the survival outcomes of HER2-positive breast cancer patients in our setting. The present study was aimed at determining the survival outcomes among HER2-positive breast cancer patients at the Oncology Department of Kenyatta National Hospital.

Methods: A hospital-based retrospective cohort design was used to evaluate the survival outcomes among patients with HER2-positive breast cancer treated from 1st January 2015 to 31st December 2019 at Kenyatta National Hospital. A total of 50 eligible HER2-positive breast cancer patients were included in the study. In the predesigned data abstraction tool, data were collected by reviewing the medical records of the patients. The data were entered and analyzed using the Statistical Package for the Social Sciences version 27 software. The mean survival time was estimated using Kaplan-Meier survival analysis.

Results: The mean age was 45.44 ± 12.218 years, with a majority (80%) of the patients being below 60 years. Most patients (64%) had advanced-stage disease. The median follow-up time for patients with curative stages of breast cancer was 41 months, while the median follow-up time for those with the advanced incurable disease was 8.5 months. The 4-year survival rate was 62.5% for those curable-stage HER2-positive breast cancer compared to 5.6% for those with metastatic disease at presentation.

Conclusion: The 4-year survival rate for both early-stage and advanced-stage HER2-positive breast cancer in our setting is suboptimal when compared to existing outcome data from health care systems where trastuzumab is more widely available.

肯雅塔国立医院人表皮生长因子受体 2-(HER2-)阳性乳腺癌患者的生存结果。
导言与其他乳腺癌亚型相比,HER2 阳性乳腺癌的预后较差,死亡率较高。曲妥珠单抗的出现极大地改变了 HER2 阳性乳腺癌的自然病史。然而,在撒哈拉以南非洲国家,这并不是一种负担得起的治疗方案。由于费用昂贵,在我们的环境中,大多数患者都没有接受曲妥珠单抗治疗以达到最佳的疾病控制效果。此外,我们还缺乏有关 HER2 阳性乳腺癌患者生存结果的全面数据。本研究旨在确定肯雅塔国立医院肿瘤科HER2阳性乳腺癌患者的生存结果:方法:采用基于医院的回顾性队列设计,评估2015年1月1日至2019年12月31日期间在肯雅塔国立医院接受治疗的HER2阳性乳腺癌患者的生存结果。研究共纳入了50名符合条件的HER2阳性乳腺癌患者。研究人员使用预先设计的数据抽取工具,通过查看患者的病历收集数据。数据使用社会科学统计软件包 27 版进行输入和分析。采用卡普兰-梅尔生存分析法估算平均生存时间:平均年龄为 45.44 ± 12.218 岁,大多数患者(80%)年龄在 60 岁以下。大多数患者(64%)为晚期患者。治愈期乳腺癌患者的中位随访时间为 41 个月,而晚期无法治愈者的中位随访时间为 8.5 个月。HER2阳性乳腺癌治愈期患者的4年生存率为62.5%,而转移性疾病患者的4年生存率仅为5.6%:结论:与曲妥珠单抗更广泛应用的医疗保健系统的现有结果数据相比,我国早期和晚期HER2阳性乳腺癌的4年生存率都不理想。
