Tumor size, along with other clinicopathological characteristics, has a prognostic role in breast cancer. Recurrence risk tends to rise as tumor size increases. Early T-stage portends a good prognosis. We aimed to investigate the recurrence-free interval rates of T1abN0 group of early breast cancer.
Patients diagnosed with pT1a and T1b, lymph node metastasis-negative breast cancer were included in the study. Clinicopathologic characteristics including recurrence, distant metastasis, and final status of the patients were obtained retrospectively from the patient files.
A total of 84 patients included. Twenty-six patients (31%) had T1a and 58 patients (69%) had T1b tumors. The 5-year distant relapse-free survival (DRFS) rate of T1ab tumors was 95.2%. The DRFS rate of T1a tumors was 96.2%, while the rate of T1b tumors was 94.8% (p=0.555). The 5-year RFS rate of T1ab tumors was 90.5%. The RFS rate of T1a tumors was 84.6%, whereas the rate of T1b tumors was 93.1% (p=0.359). The 5-year DRFS rate of hormone receptor positive group was 97%, Her-2 positive group was 81.8%, and triple negative group was 100% (p=0.041). The 5-year RFS rate of the hormone receptor positive group was 97%, Her-2 positive group was 72.7%, and triple negative group was 57.1% (p=0.001).
The results of the study provided that both T1a and T1b tumors have a good and similar prognosis.
肿瘤大小与其他临床病理特征一样,在乳腺癌中具有预后作用。复发风险往往随着肿瘤大小的增加而上升。早期T分期预示着良好的预后。我们旨在研究早期乳腺癌T1abN0组的无复发生存率。
本研究纳入诊断为pT1a和T1b、无淋巴结转移的乳腺癌患者。回顾性地从患者病历中获取包括复发、远处转移和患者最终状态在内的临床病理特征。
共纳入84例患者。26例(31%)为T1a肿瘤,58例(69%)为T1b肿瘤。T1ab肿瘤的5年远处无复发生存率(DRFS)为95.2%。T1a肿瘤的DRFS率为96.2%,而T1b肿瘤的DRFS率为94.8%(p = 0.555)。T1ab肿瘤的5年无复发生存率(RFS)为90.5%。T1a肿瘤的RFS率为84.6%,而T1b肿瘤的RFS率为93.1%(p = 0.359)。激素受体阳性组的5年DRFS率为97%,Her-2阳性组为81.8%,三阴性组为100%(p = 0.041)。激素受体阳性组的5年RFS率为97%,Her-2阳性组为72.7%,三阴性组为57.1%(p = 0.001)。
研究结果表明,T1a和T1b肿瘤均具有良好且相似的预后。
