Research priorities in metastatic breast cancer: A James Lind Alliance Priority Setting Partnership

Awe and anxiety for cancer cells: connecting scientists and patients in a holistic approach of metastasis research

BACKGROUND

Metastatic cancer is often experienced by patients as a death sentence. At the same time, translational scientists approach metastasis also as an interesting phenomenon that they try to understand and prevent. These two sides of the same coin do not mask the considerable gap that exists between the laboratory world of scientists and the life world of patients. Funding agencies nowadays increasingly demand researchers to be responsive to the values and priorities of patients and public. One approach to bridge this gap and to increase the impact of science is patient and public involvement (PPI). A concise literature review of PPI research and practice in this paper revealed that although PPI is often deployed in translational health care research, its methodology is not settled, it is not sufficiently emancipatory, and its implementation in basic and translational science is lagging behind. Here, we illustrate the practical implementation of PPI in basic and translational science, namely in the context of HOUDINI, a multidisciplinary network with the ultimate goal to improve the management of metastatic disease.

METHODS

This paper reports on a societal workshop that was organized to launch the holistic PPI approach of HOUDINI. During this workshop, societal partners, patients, and physicians discussed societal issues regarding cancer metastasis, and contributed to prioritization of research objectives for HOUDINI. In a later stage, the workshop results were discussed with scientists from the network to critically review its research strategy and objectives.

RESULTS

Workshop participants chose the development of metastasis prediction tools, effective therapies which preserve good quality of life, and non-invasive tissue sampling methods as most important research objectives for HOUDINI. Importantly, during the discussions, mutual understanding about issues like economic feasibility of novel therapies, patient anxiety for metastases, and clear communication between stakeholders was further increased.

CONCLUSIONS

In conclusion, the PPI workshop delivered valuable early-stage input and connections for HOUDINI, and may serve as example for similar basic and translational research projects.

Top 10 research priorities in colorectal cancer: results from the Colorectal Cancer Priority-Setting Partnership

BACKGROUND

Colorectal cancer (CRC) is the third most frequent cause of cancer death in the word. Which aspects of research into CRC should be accorded the highest priority remains unclear, because relevant stakeholders, such as patients, nurses, and physicians, played hardly any part in the development of research projects. The goal in forming the CRC Priority-Setting Partnership (PSP) was to bring all relevant stakeholders together to identify and prioritize unresolved research questions regarding the diagnosis, treatment, and follow-up of CRC.

METHODS

The CRC PSP worked in cooperation with the British James Lind Alliance. An initial nationwide survey was conducted, and evidence uncertainties were collected, categorized, summarized, and compared with available evidence from the literature. The as-yet unresolved questions were (provisionally) ranked in a second national wide survey, and at a concluding consensus workshop all stakeholders came together to finalize the rankings in a nominal group process and compile a top 10 list.

RESULTS

In the first survey (34% patients, 51% healthcare professionals, 15% unknown), 1102 submissions were made. After exclusion of duplicates and previously resolved questions, 66 topics were then ranked in the second survey (56% patients, 39% healthcare professionals, 5% unknown). This interim ranking process revealed distinct differences between relatives and healthcare professionals. The final top 10 list compiled at the consensus workshop covers a wide area of research topics.

CONCLUSION

All relevant stakeholders in the CRC PSP worked together to identify and prioritize the top 10 evidence uncertainties. The results give researchers and funding bodies the opportunity to address the most patient-relevant research projects. It is the first detailed description of a PSP in Germany, and the first PSP on CRC care worldwide.

Systematic Characterization of Expression Patterns and Immunocorrelations of Formin-Like Genes in Breast Cancer

Background. Members of the formin-like gene (FMNL) family are required for cytoskeleton-related processes, and their expressions are implicated to the progression of a multitude of malignancies. However, there are insufficient studies on transcription factors and promising prognosis benefit of FMNLs during the genesis of breast cancer (BrCa). Methods. The transcriptional levels of FMNL family members in primary BrCa tissues and their association with intrinsic subclasses were analyzed using the UALCAN database. Then, the prognostic values of FMNLs in BrCa patients were investigated via the Kaplan-Meier plotter. Moreover, the correlations between FMNL expression levels and immune infiltrations were analyzed using the TIMER database. In addition, the expression patterns of FMNLs in BrCa were investigated by single-cell RNA-sequencing (scRNA-seq) analysis and were validated by immunohistochemistry (IHC) staining. Results. The transcriptional level of FMNL1 was shown to be considerably increased in BrCa. It is surprising that the transcriptional quantities of FMNL2 and FMNL3 were substantially reduced. In addition, during the comparison of several BrCa subclasses, FMNL1 and FMNL2 mRNA levels of patients with HER2-positive and triple-negative BrCa subclasses increased, while FMNL3 mRNA levels reduced. With the processions of experimentation, high FMNL1 expression was hopefully linked to well clinical outcome, while high FMNL2 expression predicted poor prognosis. Moreover, FMNL1 was highly expressed in tumor-infiltrating immune cells (TIICs) in tumor tissues. Last but not least, FMNL1 was highly expressed in TIICs and served as a gene marker for TIICs. Conclusions. The fact and result which we analyzed demonstrate FMNL1 as a diagnostic marker for TIICs by comprehensively elucidating the expression patterns and changeable prognostic implications of FMNLs in BrCa clinical applications.

Top 10 research priorities for early-stage colorectal cancer: a Canadian patient-oriented priority-setting partnership

BACKGROUND

Colorectal cancer, one of the most commonly diagnosed cancers, is now being detected earlier and treatments are improving, which means that patients are living longer. Partnering with Canadian clinicians, patients and researchers, we aimed to determine research priorities for those living with early-stage colorectal cancer in Canada.

METHODS

We followed the well-established priority-setting partnership outlined by the James Lind Alliance to identify and prioritize unanswered questions about early-stage (i.e., stages I-III) colorectal cancer. The study was conducted from September 2018 to September 2020. We surveyed patients, caregivers and clinicians from across Canada between June 2019 and December 2019. We categorized the responses using thematic analysis to generate a list of unique questions. We conducted an interim prioritization survey from April 2020 to July 2020, with patients, caregivers and clinicians, to determine a shorter list of questions, which was then reviewed at a final meeting (involving patients, caregivers and clinicians) in September 2020. At that meeting, we used a consensus-based process to determine the top 10 priorities.

RESULTS

For the initial survey, 370 responses were submitted by 185 individuals; of the 98 individuals who provided demographic information, 44 (45%) were patients, 16 (16%) were caregivers, 7 (7%) were members of an advocacy group, 26 (27%) were health care professionals and 5 (5%) were categorized as "other." The responses were refined to create a list of 66 unique unanswered questions. Twenty-five respondents answered the interim prioritization survey: 13 patients (52%), 2 caregivers (8%), 3 advocacy group members (12%) and 7 health care professionals (28%). This led to a list of the top 30 questions. The final consensus meeting involved 20 individuals (10 patients [50%], 3 caregivers [15%] and 7 health care professionals [35%]), who agreed to the top 10 research priorities. The priorities covered a range of topics, including screening, treatment, recurrence, management of adverse effects and decision-making.

INTERPRETATION

We determined the top research priorities for early-stage colorectal cancer using a collaborative partnership of stake-holders from across Canada. The priorities covered a broad range of topics that could be addressed by future research, including improved screening practices, the role of personalized medicine, the management of adverse effects of treatment, decision-making and prevention of recurrence.

Identifying the top research priorities in postmastectomy breast cancer reconstruction: a James Lind Alliance priority setting partnership

BACKGROUND

Major improvements in breast cancer treatment in the last decade include advancements in postmastectomy breast reconstruction (PMBR). Unfortunately, the studies in PMBR are primarily researcher or industry led with minimal input from patients and caregivers. The aim of this study is to use the James Lind Alliance (JLA) approach to bring together the patients, caregivers and clinicians in a priority setting partnership to identify the most important unanswered research questions in PMBR.

METHODS

The JLA priority setting methodology involved four key stages: gathering research questions on PMBR from patients, caregivers and clinicians; checking these research questions against existing evidence; interim prioritisation and a final consensus meeting to determine the top 10 unanswered research questions using the modified nominal group methodology.

RESULTS

In stage 1, 3168 research questions were submitted from 713 respondents across Canada, of which 73% of the participants were patients or caregivers. Stage 2 confirmed that there were a total of 48 unique unanswered questions. In stage three, 488 individuals completed the interim prioritisation survey and the top 25 questions were taken to a final consensus meeting. In the final stage, the top 10 unanswered research questions were determined. They cover a breadth of topics including personalised surgical treatment, safety of implants and newer techniques, access to PMBR, breast cancer recurrence and rehabilitation.

INTERPRETATION

Identification of the top 10 unanswered research questions is an important first step to generating relevant and impactful research that will ultimately improve the PMBR experience for patients with breast cancer.

Emerging drugs for the treatment of triple-negative breast cancer: a focus on phase II immunotherapy trials

Introduction: Triple-negative breast cancer accounts for 10-20% of invasive breast cancers and is characterized by an aggressive phenotype and poor outcomes in the early and advanced settings compared to other breast cancer subtypes. Chemotherapy continues to be the mainstay of treatment, but recent advances have demonstrated the benefit of adding immune checkpoint inhibitors (ICIs) to chemotherapy regimens for patients with both early and advanced TNBC, particularly if PD-L1-positive. Despite these results, further improvements are needed.Areas covered: This review covers immunotherapy drugs which have recently completed, involved in ongoing or due to start phase II trials. This includes approaches to augment the response to existing ICIs, next-generation ICIs, combination treatments with targeted agents and drugs that target the tumor microenvironment. Potential development issues are also discussed.Expert opinion: The field of immunotherapy is developing rapidly and holds great promise for patients with TNBC. Promising avenues of research currently in phase II trials include targeting multiple immune checkpoints simultaneously and the addition of phosphatidylinositol 3-kinase (PI3K)/AKT inhibitors to ICI/chemotherapy regimens. A better understanding of the immunosuppressive role played by the tumor microenvironment has also been important. However, challenges remain, particularly regarding the need for more effective predictive biomarkers.
