RESUMO

Introduction: Brain metastasis is the terminal event of breast cancer with poor prognoses. Therefore, this article aimed to provide an updated summary on the development, hotspots, and research trends of brain metastasis from breast cancer based on bibliometric analysis. Method: Publications on breast cancer with brain metastasis retrieved from the Web of Science Core Collection. CiteSpace, VOSviewer, and other online bibliometric analysis platforms were used to analyze and visualize the result. Result: In totality, 693 researchers from 3,623 institutions across 74 counties and regions published a total of 2,790 papers in 607 journals. There was a noticeable increase in publications in 2006. The United States was the dominant country with the most publications followed by China. University Texas MD Anderson Cancer Center was the most productive institution, while Dana Farber Cancer Institution was the most cited. Journal of Neuro-Oncology published the most papers, while Journal of Clinical Oncology ranked first based on cocited analysis. Nancy U. Lin was the most productive and cited author with high influence. There was a focus on basic research, clinical trials, local therapy, treatment optimization, and epidemiological studies regarding brain metastases from breast cancer. References focused on pathogenesis, prevention, treatment, and prognosis were cited most frequently, among which the clinical trial of novel treatment attracted most attention from researchers. Reference citation burst detection suggested that new therapies such as the novel tyrosine kinase inhibitor and antibody-drug conjugate may lead the research trends in the future. Conclusion: High-income countries contributed more to the field of breast cancer with brain metastasis, while developing countries like China developed quickly. Furthermore, the success of novel therapies in recent years may lead to the new era of treatment of breast cancer with brain metastasis in the future.

RESUMO

Background: High serum uric acid (SUA) levels increase the risk of overall cancer morbidity and mortality, particularly for digestive malignancies. Nevertheless, the correlation between SUA level and clinical outcomes of the postoperative patients with colorectal cancer (CRC) treated by chemotherapy is unclear. This study aimed at exploring the relationship between baseline SUA level and progression-free survival (PFS), disease control rate (DCR), and safety in postoperative CRC patients receiving chemotherapy. Patients and Methods: We conducted a retrospective study to evaluate the relationship between baseline SUA level and PFS, DCR, and incidence of serious adverse events of 736 postoperative CRC patients treated with FOLFOX, FOLFIRI or XELOX at our center. Results: Data from our center suggested that high baseline SUA level is linked to poor PFS in non-metastatic CRC patients using FOLFOX (HR=2.59, 95%CI: 1.29-11.31, p=0.018) and in male patients using FOLFIRI (HR=3.77, 95%CI: 1.57-39.49, p=0.012). In patients treated by FOLFIRI, a high SUA is also linked to a low DCR (p=0.035). In patients using FOLFOX, high baseline SUA level is also linked to a high incidence of neutropenia (p=0.0037). For patients using XELOX, there is no significant correlation between SUA level and PFS, effectiveness, or safety. Conclusions: These findings imply that a high SUA level is a promising biomarker associated with poor PFS, DCR and safety of postoperative CRC patients when treated with FOLFOX or FOLFIRI.

RESUMO

UNLABELLED: This prospective, nonrandomized, case-control study evaluated the impact of (18)F-FDG PET in staging untreated squamous cell carcinoma of the buccal mucosa (BSCC) and compared the results with CT/MRI and histopathology. METHODS: Between January 2002 and April 2004, 102 untreated BSCC patients with cM0 (no evidence of distant metastatic focus on chest radiograph, liver ultrasonograph, and bone scan) were enrolled with either conventional work-up (CWU, n = 51) or PET (CWU+PET, n = 51). All were monitored for at least 6 mo. The comparative diagnostic efficacies of PET and CT/MRI were evaluated using the area under the receiver-operating-characteristic curve (AUC). The primary endpoint was the percentage reduction in futile surgery (preoperative detection of distant metastatic lesions). The secondary endpoint was the 2-y cumulative recurrence rate among study participants (with PET) compared with that of comparable control subjects (without PET). RESULTS: Significant benefits of PET compared with those of CT/MRI for BSCC patients were in the detection of locoregional (AUC, 0.973 vs. 0.928; P = 0.026), regional (AUC, 0.939 vs. 0.837; P = 0.026), and level II (AUC, 0.974 vs. 0.717; P = 0.02) lymph nodes. Two percent (1/51) of the patients experienced a reduction in futile surgery in the CWU+PET group compared with 0% (0/51) in the CWU group. However, no statistical difference was found in the 2-y locoregional control rate between the CWU and the CWU+PET groups. CONCLUSION: The role of (18)F-FDG PET for BSCC with cM0 is limited. Although PET is superior to CT/MRI in identifying cervical nodal metastases, it does not improve locoregional recurrence.
