Intervention for patient reported urinary symptoms in prostate cancer survivors: Systematic review

New Approach for Collecting Cancer Patients' Views and Preferences Through Medical Staff

PURPOSE

It is crucial for health professionals to understand patients' and families' views and preferences (PVPs) to enhance their adherence to treatments and subsequent satisfaction. Regularly and consistently collecting comprehensive information on the needs and concerns of patients/families and utilizing the information is vital for improving clinical practice and the healthcare environment. As an initial approach, this study aimed to develop a new system for appropriately collecting PVPs regarding cancer from nationwide medical staff and consider the potential utilization of PVPs in clinical practice.

METHODS

Web-based anonymous surveys were conducted with medical staff in nationwide cancer care hospitals in Japan. The surveys queried the questions, values, desires, and experiences expressed by cancer patients or their families on five topics, namely two cancer sites (colorectal and esophageal cancers) and three symptoms and signs (lymphedema, urinary symptoms, and tingling/numbness/pain) within the past year. The PVPs were compared to the five topics and staff medical specialties, and those on tingling/numbness/pain were analyzed qualitatively.

RESULTS

Among the 904 medical staff who responded to this survey, the PVPs encountered by the staff differed according to the topic and staff medical specialty. Tingling/numbness/pain was the most frequently encountered symptom, and urinary symptoms were the least encountered. Only half or fewer of the medical staff had information available regarding urinary symptoms and tingling/numbness/pain. Further, qualitative content analysis of the expressed PVPs regarding tingling/numbness/pain raised clinical questions on this topic that led to the construction of a "Questions & Answers" section on a public website in Japan.

CONCLUSION

This study suggests that collecting PVPs through nationwide cancer-related medical staff might be an efficient way to understand the specific requirements of patients/families. It would also be possible to document PVP trends according to changes in the environments of patients/families by nationwide, consistent, and continuous PVP collection.

Characterization of the prognostic values and response to immunotherapy/chemotherapy of Krüppel-like factors in prostate cancer

At present, the overall genetic and epigenetic effects of Krüppel‐like factors (KLFs) on prostate cancer (PCa) remain unclear. Therefore, we systematically investigated the molecular differences in KLFs of transcription expression, promoter methylation and genetic alteration. Univariate and multivariate Cox proportional hazard regression was used to analyse the effect on RFS and establish the prognostic signature in the TCGA cohort, MSKCC and GSE116918 cohorts employed to validate the signature. Biological pathway enrichment and the potential response to immunotherapy and chemotherapy were inferred. The transcription levels of most KLFs are associated with the clinical outcome of PCa. Gleason score (P = .009), pathology T stage (P = .006), KLF3 (P = .034), KLF5 (P = .002) and KLF7 (P = .035) were independent prognostic factors. A prognostic signature was established in the TCGA cohort (P < .001) and validated in the MSKCC (P < .001) and GSE116918 cohorts (P = .006). Demethylation of KLF5 by 5‐azacytidine led to increased protein levels, whereas knockdown of KLF5 promoted cell proliferation. Patients in KLF‐F were more likely to respond to immunotherapy (P < .001) and bicalutamide (P < .001). In summary, we found that the KLFs and clinical feature‐based signatures may improve prognosis prediction in PCa and further promote patient stratification and disease management.
