摘要
目的:癌症治疗启动时间(TTI)的延迟会对患者的预后产生负面影响。本研究旨在量化南非夸祖鲁-纳塔尔省 Inkosi Albert Luthuli 中心医院(IALCH)乳腺癌、宫颈癌和前列腺癌患者的 TTI 与生存率之间的关系,以此作为撒哈拉以南非洲(SSA)的缩影:我们分析了 2010 年至 2020 年期间在 IALCH 诊断为乳腺癌、宫颈癌或前列腺癌患者的电子病历。计算了不同治疗方式的中位TTI。为了评估治疗延迟与死亡率之间的联系,我们采用了Cox比例危险模型来估计危险比(HRs)和95%置信区间(CIs),并将乳腺癌和40岁以上的患者作为竞争事件。此外,还使用 Kruskal-Wallis 单向分析和线性回归对不同种族群体的 TTI 进行了比较:研究对象包括乳腺癌(44%)、宫颈癌(44%)和前列腺癌(12%)患者。确诊时的平均年龄分别为 62.6 岁、56.6 岁和 73.0 岁。乳腺癌患者乳房切除术的延迟时间最长(中位数为 18.4 周),其次是前列腺癌患者等待放疗的时间(中位数为 16.6 周)。与年龄较大的乳腺癌患者相比,40 岁以下的宫颈癌(HR = 2.30,95% CI:2.16-2.44,p < 0.001)或前列腺癌(HR = 1.42,95% CI:1.03-1.95,p = 0.033)患者的放疗 TTI 明显更长。接受化疗的年轻宫颈癌患者也有类似趋势。值得注意的是,所有种族群体在三种癌症的开始治疗方面都表现出严重的延迟(乳腺癌 p < 0.001,前列腺癌 p = 0.004,宫颈癌 p < 0.001):本研究发现,南非因科西-阿尔伯特-卢图利中心医院(Inkosi Albert Luthuli Central Hospital,IALCH)的乳腺癌、前列腺癌和宫颈癌患者在开始治疗(TTI)时存在严重延误。这些延误令人担忧,尤其是年轻患者和各种族背景的患者。在其他研究中,延迟开始治疗与死亡率风险的增加有关,这凸显了解决这一问题的紧迫性。此外,这项研究还为整个撒哈拉以南非洲地区未来的研究提供了一个宝贵的模式,以共同应对治疗延误的挑战,改善该地区的癌症治疗。
Treatment delays for cancer patients in Sub-Saharan Africa: South Africa as a microcosm.
Purpose: Delays in initiating cancer treatment time to treatment initiation (TTI) can negatively impact patient outcomes. This study aimed to quantify the association between TTI and survival in breast, cervical and prostate cancer patients at Inkosi Albert Luthuli Central Hospital (IALCH) in KwaZulu-Natal, South Africa, as a microcosm of Sub-Saharan Africa (SSA).
Methods: We analyzed electronic medical records of patients diagnosed with breast, cervical or prostate cancer at IALCH between 2010 and 2020. Median TTI was calculated for different treatment modalities. To assess the link between treatment delay and mortality, we employed a Cox proportional hazards model to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), treating breast cancer and patients over 40 as competing events. Additionally, Kruskal-Wallis one-way analysis and linear regression were used to compare TTI across racial groups.
Results: The study included patients with breast (44%), cervical (44%) and prostate cancer (12%). Mean age at diagnosis was 62.6, 56.6 and 73.0 years, respectively. Breast cancer patients experienced the longest delays for mastectomy (median 18.4 weeks), followed by prostate cancer patients waiting for radiotherapy (median 16.6 weeks). Significantly longer TTI for radiotherapy was observed in patients younger than 40 with cervical (HR = 2.30, 95% CI: 2.16-2.44, p < 0.001) or prostate cancer (HR = 1.42, 95% CI: 1.03-1.95, p = 0.033) compared to older breast cancer patients. Similar trends were seen for younger patients with cervical cancer receiving chemotherapy. Notably, all racial groups exhibited substantial delays in initiating treatment for all three cancers (breast p < 0.001, prostate p = 0.004 and cervical cancer p < 0.001).
Conclusion: This study identified significant delays in treatment initiation (TTI) for breast, prostate and cervical cancer patients at Inkosi Albert Luthuli Central Hospital (IALCH) in South Africa. These delays were concerning, particularly for younger patients and individuals across all racial backgrounds. Delays in treatment initiation have been linked to increased mortality risk in other studies, highlighting the urgency of addressing this issue. Furthermore, this study serves as a valuable model for future research throughout SSA to collectively address the challenges of treatment delays and improve cancer care for the region.
