Breast Cancer Surgery: A Qualitative Exploration of Concerns Over Time

As outcomes for breast cancer patients improve, addressing the side effects and distress of treatment can optimize survivorship. Although distress in breast cancer is well known in literature, there is a lack of information on how these concerns change through the phases of the cancer care continuum. Therefore, this study investigates the longitudinal trajectory of worry in patients with nonmetastatic breast cancer. Female patients with newly diagnosed stage I-III breast cancer comprised a mixed-methods, longitudinal study at a cancer center from June 2019 to June 2023. Patients completed an open-ended survey regarding their top three concerns. Responses were obtained before surgery and two weeks, three, six, nine months, and one year postoperatively. Responses were qualitatively coded and analyzed to determine themes of cancer-related distress. Participants (n = 262) were aged an average 57.53 y (±12.54), 65.8% had stage I disease at diagnosis, and 91.1% were White. Responses revealed that patients’ top three sources of concerns varied by treatment phase. Overall, patients were worried about their cancer diagnosis and the risk of recurrence. Preoperatively, patients were worried about treatment timeline, while postoperative concerns transitioned to physical appearance and surgical side effects. Breast cancer patients consistently reported worries about cancer diagnosis, recurrence, and metastasis as well as the side effects and fear of treatments. However, patient worry appeared to be intrinsically linked with their treatment phase. Therefore, support and interventions should be catered to reflect the changing patterns of patients' sources of distress to optimize breast cancer patients’ quality of life. •Sources of breast cancer patients' worry appear to be linked with treatment phase.•Distress interventions should be tailored to specific treatment phase.•Setting realistic expectations about postoperative pain to reduce distress

Multi-region sampling with paired sample sequencing analyses reveals sub-groups of patients with novel patient-specific dysregulation in Hepatocellular Carcinoma

Abstract Background Conventional differential expression (DE) testing compares the grouped mean value of tumour samples to the grouped mean value of the normal samples, and may miss out dysregulated genes in small subgroup of patients. This is especially so for highly heterogeneous cancer like Hepatocellular Carcinoma (HCC). Methods Using multi-region sampled RNA-seq data of 90 patients, we performed patient-specific differential expression testing, together with the patients’ matched adjacent normal samples. Results Comparing the results from conventional DE analysis and patient-specific DE analyses, we show that the conventional DE analysis omits some genes due to high inter-individual variability present in both tumour and normal tissues. Dysregulated genes shared in small subgroup of patients were useful in stratifying patients, and presented differential prognosis. We also showed that the target genes of some of the current targeted agents used in HCC exhibited highly individualistic dysregulation pattern, which may explain the poor response rate. Discussion/conclusion Our results highlight the importance of identifying patient-specific DE genes, with its potential to provide clinically valuable insights into patient subgroups for applications in precision medicine
