Investigating the Quality of Life for Cancer Patients and Estimating the Cost of Immunotherapy in Selected Cases

Knowledge and quality of life in cancer patients receiving immunotherapy for the first time. A cross-sectional study about being informed

PURPOSE

Patients receiving immunotherapy need to have a good understanding of how immunology works and which toxicities they can expect. This study aimed to assess patients' knowledge on their immunotherapies and their quality of life before and after receiving immunotherapy for the first time in a cancer centre.

METHODS

From July 2018 to September 2020, all patients treated at the cancer centre receiving first-time immunotherapy were invited to participate in a cross-sectional descriptive study. Non-probabilistic sampling was used to recruit 138 patients, who answered a basal ad hoc questionnaire with ten items assessing their previous knowledge on immunotherapy. Clinical variables were collected from records and by advanced clinical specialist nurses' interviews, and quality of life was evaluated at 2 points (basal and 8 weeks of treatment), using the European Organisation for Research and Treatment of Cancer-Quality of Life C30 scale.

RESULTS

Our descriptive analysis of 138 participants with solid tumours showed that 98.5% knew they were receiving immunotherapy. Regarding complications, 89.8% reported that skin reactions were a major problem. The pre-post comparison of overall health status/health-related quality of life did not show significant changes with treatment.

CONCLUSION

Our participants were comprised primarily of men with lung cancer, receiving care at a multidisciplinary outpatient unit where they got information from their oncologist and were later assessed by clinical nurse specialists. Almost all considered themselves to be well informed, despite receiving the immunotherapy for the first time. Specific expertise, skills and abilities of the health team, oncologist and nurses providing the care that patients receiving immunotherapy needs are essential.

Targeting treatment resistance in cervical cancer: A new avenue for senolytic therapies

Cervical cancer poses a significant global health challenge, particularly impacting women in economically developing nations. This disparity stems from a combination of factors, including inadequate screening infrastructure and resource limitations. However, the foremost contributor is the widespread lack of awareness and limited accessibility to Human Papillomavirus (HPV) vaccination, which is a key preventative measure against cervical cancer development. Despite advancements in cervical cancer prevention, treatment resistance remains a major hurdle in achieving improved patient outcomes. Cellular senescence, specifically the senescence-associated secretory phenotype (SASP) and its bidirectional relationship with the immune system, has been implicated in resistance to conventional cervical cancer chemotherapy treatments. The exact mechanisms by which this state of growth arrest and the associated changes in immune regulation contribute to cervical cancer progression and the associated drug resistance are not entirely understood. This underscores the necessity for innovative strategies to address the prevalence of treatment-resistant cervical cancer, with one promising avenue being the utilisation of senolytics. Senolytics are agents that have promising efficacy in clearing senescent cells from tumour tissues, however neither the utilisation of senolytics for addressing senescence-induced treatment resistance nor the potential integration of immunotherapy as senolytic agents in cervical cancer treatment has been explored to date. This review provides a concise overview of the mechanisms underlying senescence induction and the pivotal role of the immune system in this process. Additionally, it explores various senolytic approaches that hold significant potential for advancing cervical cancer research.

Arrhythmias in oncological patients: a compact overview for the clinician

Chemotherapy is the cornerstone of antineoplastic treatment in patients with malignancies. The cardiotoxic effect of antineoplastic therapy has been known for many decades. Part of chemotherapy-induced cardiotoxicity is the development of heart rhythm disturbances. This short review aims to provide a compact overview for the clinical cardiologist of the dysrhythmic potential created by antineoplastic agents in cancer survivors.

NK92 Expressing Anti-BCMA CAR and Secreted TRAIL for the Treatment of Multiple Myeloma: Preliminary In Vitro Assessment

Multiple myeloma (MM) has witnessed improved patient outcomes through advancements in therapeutic approaches. Notably, allogeneic stem cell transplantation, proteasome inhibitors, immunomodulatory drugs, and monoclonal antibodies have contributed to enhanced quality of life. Recently, a promising avenue has emerged with chimeric antigen receptor (CAR) T cells targeting B-cell maturation antigen (BCMA), expressed widely on MM cells. To mitigate risks associated with allogenic T cells, we investigated the potential of BCMA CAR expression in natural killer cells (NKs), known for potent cytotoxicity and minimal side effects. Using the NK-92 cell line, we co-expressed BCMA CAR and soluble tumor necrosis factor-related apoptosis-inducing ligand (sTRAIL) employing the piggyBac transposon system. Engineered NK cells (CAR-NK-92-TRAIL) demonstrated robust cytotoxicity against a panel of MM cell lines and primary patient samples, outperforming unmodified NK-92 cells with a mean difference in viability of 45.1% (±26.1%, depending on the target cell line). Combination therapy was explored with the proteasome inhibitor bortezomib (BZ) and γ-secretase inhibitors (GSIs), leading to a significant synergistic effect in combination with CAR-NK-92-TRAIL cells. This synergy was evident in cytotoxicity assays where a notable decrease in MM cell viability was observed in combinatorial therapy compared to single treatment. In summary, our study demonstrates the therapeutic potential of the CAR-NK-92-TRAIL cells for the treatment of MM. The synergistic impact of combining these engineered NK cells with BZ and GSI supports further development of allogeneic CAR-based products for effective MM therapy.
