Integrating Palliative Care Into the Management of Genitourinary Malignancies.

Palliative care (PC) plays a critical role in managing the difficulties associated with genitourinary malignancies. Its primary aim is to improve the overall health of patients, provide support to both patients and their caregivers, and help individuals to navigate the complex decisions about treatment and end-of-life care. PC takes a holistic approach to patient care, recognizing that genitourinary malignancies affect multiple aspects of a person's life. By addressing physical, emotional, social, and spiritual needs, PC aims to provide comprehensive support that is consistent with the patient's values and preferences. The goal is to optimize comfort, minimize distress, and enhance the patient's quality of life throughout the course of the illness. PC is not a one-off intervention, but an ongoing source of support. This article aims to provide a thorough overview of the critical elements involved in addressing the challenges posed by genitourinary cancers, emphasizing the importance of palliative interventions. We will highlight the multifaceted aspects of care and explore strategies to optimize the overall well-being of patients throughout the course of treatment for genitourinary malignancies.

Understanding and overcoming resistance to immunotherapy in genitourinary cancers.

The introduction of novel immunotherapies has significantly transformed the treatment landscape of genitourinary (GU) cancers, even becoming the standard of care in some settings. One such type of immunotherapy, immune checkpoint inhibitors (ICIs) like nivolumab, ipilimumab, pembrolizumab, and atezolizumab play a pivotal role by disturbing signaling pathways that limit the immune system's ability to fight tumor cells. Despite the profound impact of these treatments, not all tumors are responsive. Recent research efforts have been focused on understanding how cancer cells manage to evade the immune response and identifying the possible mechanisms behind resistance to immunotherapy. In response, ICIs are being combined with other treatments to reduce resistance and attack cancer cells through multiple cellular pathways. Additionally, novel, targeted strategies are currently being investigated to develop innovative methods of overcoming resistance and treatment failure. This article presents a comprehensive overview of the mechanisms of immunotherapy resistance in GU cancers as currently described in the literature. It explores studies that have identified genetic markers, cytokines, and proteins that may predict resistance or response to immunotherapy. Additionally, we review current efforts to overcome this resistance, which include combination ICIs and sequential therapies, novel insights into the host immune profile, and new targeted therapies. Various approaches that combine immunotherapy with chemotherapy, targeted therapy, vaccines, and radiation have been studied in an effort to more effectively overcome resistance to immunotherapy. While each of these combination therapies has shown some efficacy in clinical trials, a deeper understanding of the immune system's role underscores the potential of novel targeted therapies as a particularly promising area of current research. Currently, several targeted agents are in development, along with the identification of key immune mediators involved in immunotherapy resistance. Further research is necessary to identify predictors of response.

Immunotherapy has transformed the treatment landscape for many cancer types, including genitourinary malignancies such as renal and bladder cancers.However, not all patients or tumor types, such as prostate cancer, respond to this type of treatment.Understanding the mechanisms of immunotherapy resistance is critical for developing strategies to overcome these challenges.Primary resistance, which is present at the onset of treatment, can bedue to genetic abnormalities or immune system dysregulation. These factors alter the interactions between host cells and cancer cells.Adaptive resistance develops during therapy due to dynamic changes in the levels of growth factors, cytokines, and the tumor microenvironment (TME).Acquired resistance mainly occurs at the genetic and translational levels, involving the downregulation of critical human leukocyte antigen (HLA) molecules and interference with mutational repair.Future therapies may focus on detailed genetic profiling of patients to guide treatment selection and on the use of immune profile monitoring to assist in assessing responsiveness, alongside developing novel targeted therapies and ICIs.Further research is needed to identify predictors of response to ICIs.

Redefining Rare Genitourinary Cancers: An Initiative Led by the Global Society of Rare Genitourinary Tumors.

Rare cancers account for 20-25% of all cancers diagnosed annually but there is no consensus on the definition of a rare cancer and substantial geographic heterogeneity. The Global Society of Rare Genitourinary Tumors is dedicated to education and research for rare genitourinary tumors.

Genitourinary cancers updates: highlights from ASCO 2023.

Significant scientific advances in immunotherapy and targeted therapy approaches have improved clinical outcomes and increased treatment options for patients with genitourinary (GU) malignancies. We highlight the clinical trial developments released at the ASCO 2023 annual meeting, including PARP inhibitors for prostate cancer, antibody drug conjugates and fibroblast growth factor receptor inhibitors for urothelial cancer, and HIF2a inhibitors for renal cell carcinoma. Novel agents such as bispecific antibodies, chimeric antigen receptor T-cells, and radiopharmaceuticals are currently in early phase development and also have high potential impact for the GU cancer landscape. With more treatment options, the field will need to define best treatment sequencing to optimize outcomes for each patient.

Evaluación de la incidencia, factores predictivos y consideraciones sobre el tratamiento de los granulomas genitourinarios asintomáticos después de la terapia intravesical con bacilo de Calmette-Guérin / Evaluation of incidence and predictive factors, and treatment considerations for asymptomatic genitourinary granulomas after intravesical bacillus Calmette-Guérin therapy

Introducción y objetivos Aunque las complicaciones de la terapia intravesical con el bacilo de Calmette-Guérin (BCG) están bien descritas, pocas veces se ha comunicado la formación posterior de granulomas genitourinarios asintomáticos, y su estrategia de tratamiento sigue siendo controvertida. El objetivo de este estudio es evaluar la tasa de incidencia de la formación de granulomas genitourinarios asintomáticos que imitan la recurrencia del cáncer de vejiga tras el tratamiento intravesical con el BCG, así como identificar las estrategias de diagnóstico y tratamiento según las características de los pacientes. Pacientes y métodos Se realizó una revisión retrospectiva de 162 pacientes sometidos a terapia intravesical con BCG. En los pacientes que desarrollaron granulomas, se evaluó el intervalo de tiempo entre la instilación de BCG y el desarrollo del granuloma, la presencia de bacterias acidorresistentes en las muestras de patología, los resultados del cultivo/reacción en cadena de la polimerasa, las estrategias de tratamiento de las lesiones y los resultados clínicos. Resultados Se desarrollaron masas genitourinarias asintomáticas en 14 pacientes, de los cuales 5 se sometieron a evaluaciones histológicas confirmando en todos los casos una inflamación granulomatosa. Los órganos afectados fueron el riñón, la vejiga, la próstata y el pene. Aunque 5 de los 5 pacientes no recibieron tratamiento para los granulomas, a uno de ellos se le administró medicación antituberculosa para evitar el empeoramiento de la lesión durante el periodo perioperatorio de la cistoprostatectomía programada. Ninguno de los pacientes experimentó empeoramiento o recurrencia de las lesiones granulomatosas. Los pacientes que desarrollaron masas asintomáticas (n=14) eran significativamente más jóvenes que ...(AU)

Introduction and objectives Although the complications of intravesical BCG treatment are well described, asymptomatic genitourinary granulomas after BCG therapy have rarely been reported and management strategy for these conditions remains controversial. The objective of this study is to evaluate the incidence rate of asymptomatic genitourinary granuloma formation mimicking bladder cancer recurrence after intravesical bacillus Calmette-Guérin (BCG) therapy and to identify the diagnostic and treatment strategies according to patient conditions.Patients and methods A retrospective review was conducted on 162 patients who underwent intravesical BCG therapy. For patients who developed granulomas, we evaluated the time interval between BCG instillation and the development of granuloma, the presence of acid-fast bacteria on pathology specimens, culture/polymerase chain reaction results, management strategies for the lesions, and clinical outcomes. Results Asymptomatic genitourinary masses developed in 14 patients, of whom 5 underwent histological examinations and all were confirmed to have granulomatous inflammation. The affected organs included the kidney, bladder, prostate, and penis. While four of the five patients did not receive treatment for their granulomas, one patient was administered antituberculous medication to prevent worsening of the lesion during the perioperative period of the scheduled cystoprostatectomy. None of the patients experienced worsening or recurrence of granulomatous lesions. Patients who developed asymptomatic masses (n=14) were significantly younger than those who did not (P=.0076) and multivariate analysis also showed that younger age was independently associated with the development of clinically suspicious lesions (P=.032); however, none of the parameters were associated with histologically confirmed granuloma formation...(AU)

CD24 targeting with NK-CAR immunotherapy in testis, prostate, renal and (luminal-type) bladder cancer and identification of direct CD24 interaction partners.

Alternative therapeutic options targeting urologic malignancies, such as germ cell tumours, as well as urothelial, renal and prostate carcinomas, are still urgently needed. The membrane protein CD24 represents a promising immunotherapeutical approach. The present study aimed to decipher the molecular function of CD24 in vitro and evaluate the cytotoxic capacity of a third-generation natural killer (NK) cell chimeric antigen receptor (CAR) against CD24 in urologic tumour cell lines. Up to 20 urologic tumour cell lines and several non-malignant control cells were included. XTT viability assays and annexin V/propidium iodide flow cytometry analyses were performed to measure cell viability and apoptosis rates, respectively. Co-immunoprecipitation followed by mass spectrometry analyses identified direct interaction partners of CD24. Luciferase reporter assays were used to functionally validate transactivation of CD24 expression by SOX2. N- and O-glycosylation of CD24 were evaluated by enzymatic digestion and mass spectrometry. The study demonstrates that SOX2 transactivates CD24 expression in embryonal carcinoma cells. In cells of different urological origins, CD24 interacted with proteins involved in cell adhesion, ATP binding, phosphoprotein binding and post-translational modifications, such as histone acetylation and ubiquitination. Treatment of urological tumour cells with NK-CD24-CAR cells resulted in a decreased cell viability and apoptosis induction specifically in CD24+ tumour cells. Limitations of the study include the in vitro setting, which still has to be confirmed in vivo. In conclusion, we show that CD24 is a promising novel target for immune therapeutic approaches targeting urologic malignancies.

Prognostic value of various nutritional risk markers in patients hospitalized for the treatment of genitourinary cancer: A retrospective study.

BACKGROUND & AIMS: Because malnutrition adversely affects the prognosis of patients with cancer, accurate nutritional status assessment is important. Therefore, this study aimed to verify the prognostic value of various nutritional assessment tools and compare their predictability. METHODS: We retrospectively enrolled 200 patients hospitalized for genitourinary cancer between April 2018 and December 2021. Four nutritional risk markers, namely, Subjective Global Assessment (SGA) score, Mini-Nutritional Assessment-Short Form (MNA-SF) score, Controlling Nutritional Status (CONUT) score, and Geriatric Nutritional Risk Index (GNRI), were measured at admission. The endpoint was all-cause mortality. RESULTS: SGA, MNA-SF, CONUT, and GNRI values were all independent predictors of all-cause mortality (hazard ratio [HR] = 7.72, 95% confidence interval [CI]: 1.75-34.1, P = 0.007; HR = 0.83, 95% CI: 0.75-0.93, P = 0.001; HR = 1.29, 95% CI: 1.16-1.43, P < 0.001; and HR = 0.95, 95% CI: 0.93-0.98, P < 0.001, respectively) even after adjustment for age, sex, cancer stage, and surgery or medication. However, in the model discrimination analysis, the net reclassification improvement of the CONUT model (vs. SGA: 0.420, P = 0.006 and vs. MNA-SF: 0.57, P < 0.001) and GNRI model (vs. SGA: 0.59, P < 0.001 and vs. MNA-SF: 0.671, P < 0.001) were significantly improved compared to the SGA and MNA-SF models, respectively. The combination of CONUT and GNRI models also had the highest predictability (C-index = 0.892). CONCLUSIONS: Objective nutritional assessment tools were superior to subjective nutritional tools in predicting all-cause mortality in inpatients with genitourinary cancer. Measurement of both the CONUT score and GNRI might contribute to a more accurate prediction.

Adaptive Immunity in Genitourinary Cancers.

CONTEXT: While urothelial and renal cell cancers have exhibited modest responses to novel immune checkpoint inhibitors targeting the programmed death ligand 1 and its receptor, response rates in patients with prostate cancer have remained poor. The factors underlying suboptimal outcomes observed in patients treated with novel immunotherapies are still to be resolved. OBJECTIVE: To review the literature and describe the key adaptive immune physiological events associated with cancer progression and therapeutic response in genitourinary (GU) cancers. EVIDENCE ACQUISITION: We performed a nonsystematic, collaborative narrative review to highlight recent advancements leading to the current state of knowledge on the critical mediators of antitumor adaptive immunity to GU cancers. Further, we discuss the findings on the pre- and post-treatment immunological events that either are unique to each of the three cancer types or exhibit overlapping clinical associations. EVIDENCE SYNTHESIS: Aging-associated immune function decline is a major factor underlying poor outcomes observed in patients treated with both conventional and novel immunotherapies. Other cancer immunobiological aspects associated with suboptimal responses in GU cancers include the overall tumor mutational burden, mutations in specific tumor suppressor/DNA damage repair genes (KDM6A, PTEN, STAG2, TP53, ATM, and BRCA2), and abundance of multiple functional states of adaptive immune cells and their spatiotemporal localization within the tumor immune microenvironment. Understanding these mechanisms may potentially lead to the development of prognostic and predictive biomarkers such as immune cell infiltration profiles and tertiary lymphoid structures (TLSs) that associate with variable clinical outcomes depending on the nature of the novel immunotherapeutic approach. Implementation of newer immune-monitoring technologies and improved preclinical modeling systems will augment our understanding of the host and tumor intrinsic factors contributing to the variability of responses to immunotherapies. CONCLUSIONS: Despite the tremendous progress made in the understanding of dynamic and static adaptive immune elements within the tumor immune landscape, several knowledge gaps remain. A comprehensive knowledge thus gained will lead to precision immunotherapy, improved drug sequencing, and a therapeutic response. PATIENT SUMMARY: We performed a collaborative review by a diverse group of experts in the field to examine our understanding of the events and crosstalk between cancer cells and the patient's immune system that are associated with responses to novel immunotherapies. An evolving understanding of tumor-intrinsic and host-related immune alterations, both before and after therapy, will aid in the discovery of promising markers of responses to immunotherapy as well as the development of unique therapeutic approaches for the management of genitourinary cancers.

[Alternative medicine in uro-oncology]. / Alternativmedizin in der Uroonkologie.

BACKGROUND: Alternative medicine is used instead of conventional therapy. Some patients use it in parallel with conventional medicine. OBJECTIVE: Narrative compilation of the evidence on alternative medicine in the (uro)oncological context. MATERIALS AND METHODS: A selective literature search in MEDLINE via PubMed was performed. RESULTS: The data on 3­bromopyruvate, Miracle Mineral Supplement (MMS), insulin-potentiated therapy, base therapy, hyperthermia, Artemisia annua, amygdalin (vitamin B17), Amanita therapy, homeopathy, apitherapy, dendritic cells, galavit, Germanic new medicine, and spiritual healing show either no or little clinical evidence of efficacy or clearly exhibit a negative benefit-risk profile. CONCLUSIONS: Alternative medicine is pseudo-medicine that may have a positive effect on mental well-being in the short term, but is mostly associated with disadvantages for the patient in the long term.

Application of Internet-based multidisciplinary management in patients with genitourinary cancers in China: A brief introduction to a new model of healthcare service for cancer survivors during COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has triggered multiple global healthcare system crises. Apart from the pandemic itself, the travel restriction and social distance policy for the purpose of epidemic control has cast a shadow on the management of cancer survivors. Cancer survivors suffered a double blow from both the epidemic and cancer. To deal with the challenge, we explored a new Internet-based patient management model. This model has overcome the limitation of time and space and thus can help oncologists to provide remote multidisciplinary healthcare services for cancer survivors. These patients can get high-quality cancer management from multidisciplinary experts without too much transportation. This model has been applied in patients with genitourinary cancers and proved to be effective and efficient. Our study demonstrated that more patients benefited from this model during the pandemic of COVID-19, especially in those affected heavily by COVID-19. These results suggested that it can also give insight into the management of other cancer survivors in China. Given the long-term impact of the COVID-19 pandemic, we would like to introduce our new model of healthcare service and the application of Internet-based multidisciplinary management to our global peers and medical industries to help their cancer survivors who are delayed in treatment due to the COVID-19 pandemic.

Delayed urologic cancer care in the COVID-19 pandemic: Patients' experiences.

OBJECTIVE: To understand experiences of patients with genitourinary cancer who experienced delayed cancer care due to the COVID-19 pandemic. METHODS: We conducted a mixed methods study with an explanatory sequential design. Qualitative findings are reported here. Patients with muscle invasive bladder, advanced prostate or kidney cancer were eligible. Participants were selected for interviews if they self-reported low (0-3/10) or high (6-10/10) levels of distress on a previous survey. Participants were interviewed about their experiences. Interviews were transcribed, coded and categorised using thematic data analysis methodology. RESULTS: Eighteen patients were interviewed. Seven had prostate cancer, six bladder cancer and five kidney cancer. Six themes were derived from the interviews: (1) arriving at cancer diagnosis was hard enough, (2) response to treatment delay, (3) labelling cancer surgery as elective, (4) fear of COVID-19 infection, (5) quality of patient-provider relationship and communication and (6) what could have been done differently. CONCLUSION: These findings offer insight into the concerns of patients with genitourinary cancers who experienced treatment delays due to COVID-19. This information can be applied to support patients with cancers more broadly, should treatment delays occur in the future.

Genomic Sequencing Should Not be Part of the Standard of Care for Most Urologic Cancers.

There are currently few situations in which genomic testing is actionable for genitourinary tumors. Without clear indications or treatment paradigms, genomic sequencing cannot be recommended as a standard of care for genitourinary tumors.

Integration of Palliative and Supportive Care Into the Management of Genitourinary Malignancies.

Patients with genitourinary malignancies are typically cared for by a multidisciplinary team of urologists, medical oncologists, and radiation oncologists. For the past decade, integration of palliative and supportive care (PSC) into routine oncological care has been advocated by leading oncology organizations. Despite these recommendations, current evidence suggests that integration of PSC for patients with routine genitourinary malignancies is lacking. In this article, we first review the current evidence for integration of palliative care and the data suggesting an unmet need for people with genitourinary malignancies. We then provide a potential framework that examines the needs of these patients. We show an example of a potential opportunity for integration of PSC into routine multidisciplinary oncologic care that can help improve patient care by meeting these unmet patient needs. Finally, we discuss potential opportunities for integration of PSC that can provide an opportunity to understand the mechanism of benefit of PSC for improving patient-centered care.

The Cardiologist's Role in the Management of Patients with a Genitourinary Cancer.

BACKGROUND: Increased life expectancy due to improved cancer prognosis, shared determinants (e.g., tobacco use), and cardiovascular toxicities related to cancer therapies, including the adverse cardiometabolic effects of androgen deprivation therapy for prostate cancer, make cardiovascular disease an frequent and important co-morbidity in patients with a genitourinary malignancy. Complex cardiovascular disease can pose significant challenges in the management of these patients given the uncertainties related to the best approach to reconcile ischemic and bleeding risks, and the role of invasive cardiovascular interventions in individuals with advanced cancer. In this review, we discuss the current evidence that informs decision-making in this clinical context.

Genitourinary Tract Tumors in Children: An Update.

BACKGROUND: Genitourinary tract tumors in children are less common than in adults. Most of these tumors have different genetic backgrounds, clinical presentation, and oncologic behavior than their adult counterpart. As a result of low prevalence in children, some of the treatment approaches and recommendations are based on treatment experience in adult patients. However, thanks to scientific and technological development, survival rates have risen considerably. OBJECTIVE: This paper presents a review of the principal features of the tumors involving the genitourinary tract in children and an update in genetic background, diagnosis, and treatment. METHODS: A narrative review was performed on published literature about genitourinary tract tumors in pediatric patients. Papers presented in English and Spanish literature were reviewed. PubMed, Science Direct, and SciELO databases were used to collect information and present this article. RESULTS: Kidney tumors are the most common type of genitourinary tumors in children. Among those, Wilms tumor represents the majority of cases and shows the successful work of clinical trial groups studying this tumor type. Other tumors involving the genitourinary tract in children include Rhabdomyosarcoma, Transitional cell carcinoma, Testicular, and Adrenal tumors. CONCLUSION: Genitourinary tract tumors in children represent significant morbidity and economic burden, so awareness in early diagnosis represents improvement in treatment, clinical, and oncological outcomes.
