Breast cancer fatality rates are high in low- and middle-income countries because of the late stage at diagnosis. We investigated patient-mediated determinants for late-stage presentation of breast cancer in Egypt.
A case-case comparison was performed for 343 women with breast cancer, comparing those who had been initially diagnosed at Stage I or II with those diagnosed at Stage III or IV. Patients were recruited from the National Cancer Institute of Cairo University and Tanta Cancer Center in the Nile delta. Patients were either newly diagnosed or diagnosed within the year preceding the study. Interviews elicited information on disease history and diagnosis, beliefs and attitudes toward screening practices, distance to treatment facility, education, income, and reproductive history.
Forty-six per cent of the patients had presented at late stage. Women seen in Cairo were more likely to present at late stages than patients in Tanta (OR=5.05; 95% CI=1.30, 19.70). Women without any pain were more likely to present at later stage (OR=2.68; 95% CI=1.18, 6.08). Knowledge of breast self-examination increased the likelihood of women to present in early stages significantly (OR=0.24; 95% CI=0.06, 0.94).
Despite increasing numbers of cancer centers in Egypt during the past 20 years, additional regional facilities are needed for cancer management. In addition, increasing awareness about breast cancer will have significant long-term impact on breast cancer prevention.
由于诊断较晚,中低收入国家的乳腺癌死亡率较高。我们研究了埃及患者介导的导致乳腺癌晚期表现的决定因素。
对 343 名乳腺癌患者进行了病例对照研究,将那些最初诊断为 I 期或 II 期的患者与那些诊断为 III 期或 IV 期的患者进行了比较。患者是从开罗大学国家癌症研究所和尼罗河三角洲的坦塔癌症中心招募的。患者要么是新诊断的,要么是在研究前一年内诊断的。访谈中获取了有关疾病史和诊断、对筛查实践的信念和态度、到治疗机构的距离、教育程度、收入和生殖史的信息。
46%的患者出现晚期表现。在开罗就诊的女性比在坦塔就诊的女性更有可能出现晚期(OR=5.05;95%CI=1.30,19.70)。没有任何疼痛的女性更有可能出现晚期(OR=2.68;95%CI=1.18,6.08)。了解乳房自我检查显著增加了女性早期就诊的可能性(OR=0.24;95%CI=0.06,0.94)。
尽管在过去 20 年中埃及的癌症中心数量有所增加,但仍需要更多的区域癌症管理设施。此外,提高对乳腺癌的认识将对乳腺癌预防产生重大的长期影响。
