Long-Term Follow-Up in Medullary Thyroid Carcinoma Patients

After surgery, patients with MTC (medullary thyroid carcinoma) should be assessed for the presence of residual disease, the localization of metastases, and the identification of progressive disease. Postoperative staging is used to separate low-risk patients from high-risk patients with MTC. In addition to the TNM system, further histological staging with Ki67, mitotic count, tumor necrosis, and molecular analysis of somatic RET mutations is helpful for the stratification of patients in different prognostic categories. The number of lymph node metastases and involved compartments as well as postoperative Ctn (calcitonin) and CEA (carcinoembryonic antigen) levels should also be documented. Postoperative nonmeasurable Ctn levels are associated with a favorable outcome. In patients with basal serum Ctn levels less than 150 pg/ml following thyroidectomy, persistent or recurrent disease is almost always confined to lymph nodes in the neck. If the postoperative serum Ctn level exceeds 150 pg/ml, patients should be evaluated by imaging procedures, including neck and chest CT (computed tomography), contrast-enhanced MRI, US of the liver, bone scintigraphy, MRI of the bone and positron emission tomography (PET)/CT. One can estimate the growth rate of MTC metastases from sequential imaging studies using response evaluation criteria in solid tumors (RECIST) that document increases in tumor size over time and by measuring serum levels of Ctn or CEA over multiple time points to determine the tumor marker doubling time. One of the main challenges remains finding effective adjuvant and palliative options for patients with metastatic disease. Patients with persistent or recurrent MTC localized to the neck and slightly elevated Ctn levels following thyroidectomy might be candidates for neck reoperations depending on the extent of the tumor. Once metastases appear, the clinician must decide which patients require therapy, balancing the frequently slow rate of tumor progression associated with a good quality of life and suggesting active surveillance against the limited efficacy and potential toxicities of local and systemic therapies. Considering that metastatic MTC is incurable, the management goals are to provide locoregional disease control, palliate symptoms such as diarrhea, palliate symptomatic metastases causing pain or bone fractures, and control metastases that threaten life through bronchial obstruction or spinal cord compression. This can be achieved by palliative surgery, EBRT (external beam radiation therapy) or systemic therapy using multikinase inhibitors (MKIs) targeting RET or selective RET inhibitors requiring genetic testing prior to the initiation of therapy.

BACKGROUND

British Sarcoma Group guidelines for the management of GIST were initially informed by those published by the European Society of Clinical Oncology. This update was written by a group of experts to includes a discussion of the highlight improvements in our knowledge of the disease and recent treatment developments. The guidelines include sections on Incidence, Aetiology, Diagnosis, including risk assessment, Treatment and Follow-up.

METHODS

A careful review of the literature was performed to ensure that wherever possible recommendations are supported by the results of clinical trials or substantive retrospective reports. Areas of uncertainty are indicated appropriately.

CONCLUSION

Guidelines represent a consensus view of current best clinical practice. Where appropriate, key recommendations are given and the levels of evidence and strength of recommendation gradings are those used by the European Society for Medical Oncology (ESMO).

Definitive treatment for primary urethral cancer: A single institution's experience with organ-preserving brachytherapy

BACKGROUND

Radical urethectomy ± cystectomy has long represented the standard of care for rare primary urethral cancer (PUC). With our analysis, we want to demonstrate the efficacy and safety of brachytherapy (BT) of urethra for organ preservation.

MATERIALS AND METHODS

We analyzed treatment procedures and results of 3 patients with PUC, which have been treated in our department between 2011 and 2020 with brachytherapy. One male patient underwent brachytherapy with chemoradiotherapy after transurethral resection (TUR). Brachytherapy has been performed as high-dose-rate (HDR) boost with a cumulative dose of 8 Gy (9.3 Gy EQD2-α/β = 10 Gy). The 2 further female patients have been treated with sole pulsed-dose-rate (PDR) brachytherapy with a total dose of 49.9 Gy (50.3 Gy EQD2-α/β = 10 Gy) and 62.2 Gy (64.6 Gy EQD2-α/β = 10 Gy).

RESULTS

Median follow-up was 103 months (41-153). No local recurrence occurred and all patients are still alive. For the male patient we documented Grade 3 cystitis. As late side effects the pre-existing Grade 2 incontinence worsened to Grade 3. Among female patients one developed Grade 3 vaginal synechiae. There was no Grade ≥4 toxicity.

CONCLUSION

Brachytherapy in PUC is a feasible and promising option with high local control rate and tolerable toxicity. It provides a good alternative to surgery for organ preservation in selected patients.

Application progress of nanomaterials in the treatment of prostate cancer

Prostate cancer is one of the most common malignant tumors in men, which seriously threatens the survival and quality of life of patients. At present, there are serious limitations in the treatment of prostate cancer, such as drug tolerance, drug resistance and easy recurrence. Sonodynamic therapy and chemodynamic therapy are two emerging tumor treatment methods, which activate specific drugs or sonosensitizers through sound waves or chemicals to produce reactive oxygen species and kill tumor cells. Nanomaterials are a kind of nanoscale materials with many excellent physical properties such as high targeting, drug release regulation and therapeutic monitoring. Sonodynamic therapy and chemodynamic therapy combined with the application of nanomaterials can improve the therapeutic effect of prostate cancer, reduce side effects and enhance tumor immune response. This article reviews the application progress of nanomaterials in the treatment of prostate cancer, especially the mechanism, advantages and challenges of nanomaterials in sonodynamic therapy and chemodynamic therapy, which provides new ideas and prospects for research in this field.

Clinical Outcomes of Micropapillary Urothelial Carcinoma of the Bladder Treated With Radical Cystectomy

Background/Aim

This study examined the treatment outcomes of radical cystectomy (RC) for micropapillary subtype (MPS) bladder cancer treated at our hospital.

Patients and Methods

Histopathological findings of RC specimens collected from 2003 to 2020 were evaluated. Recurrence-free survival (RFS) and overall survival (OS) after RC, as well as the efficacy of chemotherapy in cases of recurrence, were retrospectively assessed.

Results

Of 202 patients who underwent RC, seven (3.4%) had MPS bladder cancer. All seven patients underwent immediate RC without neoadjuvant chemotherapy. The median patient age was 58 years (range=52-71 years), and all patients were male. After RC, median RFS was 14 months (range=6-115 months), and median OS was 31 months (range=18-115 months). The clinical tumor stage was cT1 or lower in two patients (28.5%), cT2 in two patients (28.5%), and cT3 or higher in three patients (42.8%). No preoperative lymph node metastasis was observed. The pathological tumor stage was pT1 or lower in one patient (14.2%), pT2 in one patient (14.2%), and pT3 or higher in five patients (71.4%). The pathological lymph node stage was observed in five patients (71.4%). Although six of seven patients (85.7%) received adjuvant chemotherapy, all patients experienced relapse. The objective response rates of primary and secondary chemotherapy at relapse were both 33%. One patient received immune checkpoint inhibitor therapy and maintained stable disease for 12 months.

Conclusion

The recurrence rate after RC for MPS bladder cancer was high, and prognosis was poor.

Ursodeoxycholic acid inhibits the uptake of cystine through SLC7A11 and impairs de novo synthesis of glutathione

Ursodeoxycholic acid (UDCA) is a naturally occurring, low-toxicity, and hydrophilic bile acid (BA) in the human body that is converted by intestinal flora using primary BA. Solute carrier family 7 member 11 (SLC7A11) functions to uptake extracellular cystine in exchange for glutamate, and is highly expressed in a variety of human cancers. Retroperitoneal liposarcoma (RLPS) refers to liposarcoma originating from the retroperitoneal area. Lipidomics analysis revealed that UDCA was one of the most significantly downregulated metabolites in sera of RLPS patients compared with healthy subjects. The augmentation of UDCA concentration (≥25 μg/mL) demonstrated a suppressive effect on the proliferation of liposarcoma cells. [15N2]-cystine and [13C5]-glutamine isotope tracing revealed that UDCA impairs cystine uptake and glutathione (GSH) synthesis. Mechanistically, UDCA binds to the cystine transporter SLC7A11 to inhibit cystine uptake and impair GSH de novo synthesis, leading to reactive oxygen species (ROS) accumulation and mitochondrial oxidative damage. Furthermore, UDCA can promote the anti-cancer effects of ferroptosis inducers (Erastin, RSL3), the murine double minute 2 (MDM2) inhibitors (Nutlin 3a, RG7112), cyclin dependent kinase 4 (CDK4) inhibitor (Abemaciclib), and glutaminase inhibitor (CB839). Together, UDCA functions as a cystine exchange factor that binds to SLC7A11 for antitumor activity, and SLC7A11 is not only a new transporter for BA but also a clinically applicable target for UDCA. More importantly, in combination with other antitumor chemotherapy or physiotherapy treatments, UDCA may provide effective and promising treatment strategies for RLPS or other types of tumors in a ROS-dependent manner.

The Global RAdical Cystectomy Evaluation and Management (GRACEM) pathway: single-centre prospective observational cohort study protocol

Background

Despite guideline recommendations, few institutions have implemented clinical pathways that incorporate frailty into routine decision-making for patients undergoing radical cystectomy (RC). This paper presents an integrated clinical pathway designed to address the needs of frail patients undergoing RC. The purpose of the study is to determine whether a multifaceted prevention programme that tailors interventions to the syndromic components of frailty can improve postoperative morbidity and recovery time for patients. New insights will be gained into how to optimize the physical and mental status and quality of life of patients before and after surgery, up to 1 year later.

Study design

The Global RAdical Cystectomy Evaluation and Management (GRACEM) study is a prospective, observational, single-centre, 2-year cohort study. Patient enrolment began on 27 April 2023, and results are pending.

Endpoints

The primary endpoints are postoperative morbidity and the in-hospital postoperative care burden. Postoperative morbidity is measured by the number of early (up to 1 month) and late (over 1 month and up to 12 months) complications, graded by severity according to the Clavien-Dindo classification. In-hospital postoperative care burden is measured by the number and duration of key care processes as recorded by the Care Process Monitoring Chart, a tool developed for this study. Secondary endpoints are changes in frailty and health-related quality of life (HRQoL) from pre-intervention to planned follow-up up to 1 year. Frailty is assessed with the Functional Limitations and Geriatric Syndromes Frailty Questionnaire (FLIGS-FQ), another ad hoc tool. HRQoL is assessed using the EQ-5D-5L questionnaire combined with the cystectomy-specific FACT-Bl-cys index from the first month of follow-up.

Patients and methods

The GRACEM study includes patients with non-metastatic, histologically confirmed, muscle-infiltrating bladder cancer who underwent RC surgery with curative intent. This study is unique in that the GRACEM Core Team shares decision-making throughout the pathway, from before the intervention to the end of the patient's follow-up. The pathway involves the patient, family members and community services.

Potentially paraneoplastic glomerulopathies in a Brazilian cohort: a retrospective analysis

INTRODUCTION

Glomerular diseases can be associated with solid or hematopoietic malignancies. The prevalence of these associations varies according to the studied glomerular disease. This study aimed to evaluate the frequency and type of neoplasms in patients with glomerular diseases as well as their clinical, laboratory, and histopathological features and the relationship with immunosuppressive therapy.

METHODS

This was a retrospective, descriptive, observational, longitudinal study that reviewed 4,820 medical records and included 95 patients with glomerular disease and neoplasms. Demographic, clinical, laboratory, and histologic data were collected.

RESULTS

The prevalence of neoplasms was 1.97% (95 patients; 81 [85.3%] malignant, 14 [14.7%] benign). Hematologic malignancies (35.8%) showed the highest prevalence, followed by colon, rectal, and gynecologic tumors. The glomerulopathy with the highest frequency was membranous glomerulopathy (MGN, 25 patients, 35.7%). The dose of the immunosuppressive agents among patients with neoplasms before or after immunosuppression was not statistically different. Neoplasm was diagnosed before glomerulopathy in 53% of patients. Among cases in which neoplasms were diagnosed after glomerulopathy, 43% were diagnosed in the first year of follow-up of the renal disease. The predominant syndrome at presentation was nephrotic syndrome. Progression to chronic kidney disease stage 5 at the end of follow-up occurred in 8.4% of the cases.

CONCLUSIONS

Neoplasms manifested before or, less frequently, after the diagnosis of glomerular diseases. As neoplasms diagnosed after presentation of glomerulopathy often appeared early after this diagnosis, it is necessary to be aware of neoplasms during the first year of follow-up of glomerulopathies, especially in patients with nephrotic syndrome, and MGN.

Navigating the Surgical Pathway for Frail, Older Adults Undergoing Colorectal Surgery

Adults ≥ 65 years of age comprise nearly 20% of the U.S. population and over half of surgical patients. Older adults, particularly when frail, may require additional preoperative evaluation and counseling, specialized hospital care, and may experience more noticeable physical and cognitive changes than younger or healthier patients. Surgeons can assess frailty and risk using several frailty measures, as data exist demonstrating worse perioperative outcomes among patients undergoing colorectal surgery. Prehabilitation programs have not been shown to improve surgical outcomes for colorectal surgery patients but may help maintain physical function or hasten recovery to baseline around the time of surgery, particularly for frail patients. Functional decline and delirium are common postoperatively in older adult patients, particularly those who are frail at baseline, and should be discussed with at-risk older adults. Primary care physicians and geriatricians can help with in-depth evaluation of frailty and geriatric syndromes. Special attention to the risks, outcomes, and care of older adults considering or undergoing colorectal surgery can help inform decision-making, which may facilitate goal-concordant care.

Incidence and survival of rare adult solid cancers in Europe (EUROCARE-6): A population-based study

BACKGROUND

Rare cancers correspond to approximately 200 clinical entities, which can be grouped into 12 families. Updated data are available for childhood and haematological cancers, ie, for only two of the 12 families of rare cancer. We provide incidence and survival for the remaining ten families of rare adult solid cancers (RAC), across 29 EU Member States and over time. We also evaluate the association between resources invested in health and survival from RACs.

METHODS

We used the EUROCARE-6 database, which includes data from 108 cancer registries from 29 countries. We calculated incidence rates (IR) and 5-year relative survival (RS) for cases diagnosed during 2006-2013. We calculated 5-year RS in the follow-up period 2010-2014 using the period approach (last follow-up: December 31, 2014). We estimated changes in 5-year RS and IR over the period 2000-2013. We used a forest plot to report the differences in RS among countries with the highest and lowest health spending.

RESULTS

RACs are heterogeneous in terms of incidence, survival, sex, and age distribution. Several RACs (eg, those of the hypopharynx, small intestine, and trachea) still have a 5-year RS < 30 %, which is not improving. Survival differs among European countries and is higher in countries with the greatest investments in health. The incidence of smoking-related RACs is decreasing but rising in HPV-related RACs.

CONCLUSION

Investments in health and healthcare networks at national and European level can help increase the survival of RACs, especially those requiring centralisation of care (eg, bone sarcomas, penile cancer). These investments are critical considering that survival from RACs is not significantly improving. Our results unmask the heterogeneity of RACs, which needs to be considered in clinical trial design. Finally, our findings support the importance of prevention strategies for known risk factors such as smoking.

Oncologic and fertility outcomes in patients with juvenile granulosa cell tumor - a retrospective single centre analysis

BACKGROUND

Granulosa cell tumors (GCTs) are rare neoplasia that account for less than 5 % of all the ovarian tumors. Juvenile GCT histotype is generally observed in adolescent and young women, representing a very rare disease, so only a paucity of data are present in literature. The aim of this study is to analyse the oncologic and fertility outcome in our case series of juvenile GCTs.

METHODS

Clinicopathological data were retrospectively collected and analysed from a cohort of 30 patients ovarian juvenile GCTs treated at IRCCS San Gerardo dei Tintori Hospital, Monza, between 1980 and 2024.

RESULTS

The median age of disease onset was 21.5. Among patients enrolled in the study, 80.0 % (24/30) were stage I (16/26, 1/26 and 7/26 of stage IA, IB and IC, respectively), 6.7 % (2/30) were stage II and 13.3 % stage III (4/30). In 86.7 % (26/30) of patients, a fertility-sparing surgery was carried out, while 13.3.% (4/30) of patients underwent radical surgery. Adjuvant chemotherapy was administered in 20.0 % (6/30) of cases, while 80.0 % (24/30) were followed only with surveillance. Three patients in thirty (10.0 %) relapsed and died of disease despite multi-therapeutic approaches. All of them had advanced stages of disease at time of diagnosis.

CONCLUSIONS

Juvenile GCT appears to have a good prognosis at stage I disease. However, advanced stage represents a hard challenge for clinicians, showing a high rate of relapse and mortality.

Radiation therapy for stage IIA/IIB seminomas: Back to the future?

Seminoma is a highly curable disease; therefore, long-term morbidity of oncological treatment represents a crucial stake. In view of the considerable advances made in radiotherapy in the past decade, we aim to shed light on current and future strategies that hold promises for the management of stage II seminoma.

Assessment of Rare Cancers and Sarcoma Policy and Sarcoma Drug Approvals in Latin America: A Report From the LACOG Sarcoma Group

PURPOSE

The availability of drugs and national public policies for patients with rare cancers, including sarcomas, varies in different parts of the world.

METHODS

In this manuscript, we have conducted a comprehensive analysis to evaluate rare cancer policies in Latin American countries' national policy documents. Additionally, we have reviewed the approvals for sarcoma drugs in selected Latin American countries and compared them with US Food and Drug Administration (FDA) and European Medicines Agency (EMA) approvals.

RESULTS

The documents reviewed showed a lack of explicit focus on rare cancers, with no mention in 70% of the countries analyzed. Drug approval data reveal that in the last 15 years, the FDA and EMA have approved 19 and 13 drugs for sarcoma, whereas their Latin American counterparts, namely ANVISA, ANMAT, and COFEPRIS, approved six, eight, and seven drugs, respectively.

CONCLUSION

Our data suggest that improving rare cancer and sarcoma care in Latin America requires enhanced collaboration for better rare cancer policies.

Co‑occurrence of clear cell renal cell carcinoma and bladder urothelial carcinoma: A case report and literature review

The co-occurrence of clear cell renal cell carcinoma (ccRCC) and bladder urothelial carcinoma (bUC) is rare, and owing to the lack of a unified treatment plan, the prognosis is poor. The present report describes the case of a 65-year-old male patient with a history of smoking and no history of malignant tumors who presented with hematuria at the Huanghe Sanmenxia Hospital Affiliated to Henan University of Science and Technology (Sanmenxia, China) in July 2021. Urinary system computed tomography urography revealed a right renal tumor, and cystoscopy revealed intravesical lesions. The patient underwent transurethral resection of a bladder tumor + laparoscopic partial nephrectomy + laparoscopic radical cystectomy and bilateral ureterostomy. Pathological examination revealed right-sided ccRCC (pT1aN0M0) and high-grade invasive bUC (pT2N0M0). After surgery, the patient underwent bilateral ureteral single J tube replacement in the outpatient clinic every 3 months. In September 2022, the patient presented with a mass on the right side of the neck. Further examination revealed a space-occupying lesion in the lower part of the left kidney and space-occupying lesions in the neck, axilla, mediastinal lymph nodes and liver. A neck lymph node puncture biopsy suggested UC, and the patient was diagnosed with metastatic UC (T4N0M1). The patient received tislelizumab (200 mg once every 3 weeks) + sunitinib (50 mg/day, administered for 4 weeks with a 2-week interval) for a total of 2 months and died of an advanced tumor in January 2023. In addition, the data of 36 patients with ccRCC and bUC from the literature were analyzed for the present report. The results showed that the median age at first onset was 56.5 years (range, 31-82 years) and the male-to-female ratio was 6:1. Smoking and male sex may be risk factors for this disease, which has a median survival time of 47.5 months. The survival analysis results showed that the pathological stage of bladder cancer may be associated with its prognosis. The present study reviews the potential risks, clinicopathological characteristics and treatment methods of co-occurrence of clear ccRCC and bUC. In conclusion, the high-risk factors for the co-occurrence of ccRCC and bUC were smoking and male sex, and the median survival time was 47.5 months. The pathological stage of bladder cancer may be related to the prognosis.

Physical performance tests have excellent reliability in frail and non-frail patients with prostate cancer

PURPOSE

Our aim was to investigate the test-retest reliability of the 2-min walk test (2MWT), timed up and go test (TUG), and five times sit-to-stand test (FTSST) in prostate cancer (PC) patients.

METHODS

This study was conducted with 73 patients who were classified into two groups as frail and non-frail determined by the Geriatric-8 questionnaire. Patients performed the 2MWT, TUG, and FTSST tests for two times. The test-retest reliability of the 2MWT, TUG, and FTSST was assessed by calculating the intraclass correlation coefficient (ICC). The standard error of measurement (SEM95) and minimal detectable change (MDC95) values were calculated.

RESULTS

All tests showed excellent test-retest reliability for both groups (ICC(2.1) > 0.90). The SEM95 and MDC95 values of 2MWT were 3.09, 8.57, and 3.15 m, 8.73 m for frail and non-frail groups. The SEM95 and MDC95 values of TUG for the frail group were 0.6 and 1.66 and 0.43 and 1.19 for the non-frail group, respectively. The SEM95 and MDC95 values of FTST for the frail group were 0.68 and 1.88 and for the non-frail group 0.86 and 2.38.

CONCLUSIONS

The 2MWT, TUG, and FTSST showed excellent reliability in frail and non-frail older adults with PC which can be used to assess physical performance.

Targeted Next-Generation Sequencing in Succinate Dehydrogenase-Deficient GI Stromal Tumor Identifies Actionable Alterations in the PI3K/mTOR Pathway

PURPOSE

Less than 5% of GI stromal tumors (GISTs) are driven by the loss of the succinate dehydrogenase (SDH) complex, resulting in a pervasive DNA hypermethylation pattern that leads to unique clinical features. Advanced SDH-deficient GISTs are usually treated with the same therapies targeting KIT and PDGFRA receptors as those used in metastatic GIST. However, these treatments display less activity in the absence of alternative therapeutic options. Therefore, it is critical to identify novel actionable alterations in SDH-deficient GIST.

PATIENTS AND METHODS

We performed a single-center, retrospective analysis of patients with SDH-deficient GIST together with next-generation sequencing (NGS) analysis from their respective tumor samples to identify mutations and copy number alterations and chromosomal alterations. NGS-tailored treatment was implemented whenever possible.

RESULTS

Seventeen tumor samples from 14 patients with SDH-deficient GIST underwent NGS. Mutational load was low, although three patients (21%) displayed molecular events in relapse samples leading to PI3K/mTOR pathway hyperactivation. mTOR inhibition with everolimus obtained a sustained tumor response in a heavily pretreated patient. Other alterations, largely present in late-stage patients, uncovered genes involved in cell cycle regulation, telomere maintenance, and DNA damage repair. Chromosomal arm-level alterations differed from the canonical cytogenetic progression in KIT/PDGFRA-mutant GIST.

CONCLUSION

This molecular landscape of SDH-deficient GIST uncovers novel molecular alterations, mostly in relapse and/or previously pretreated patients. The identification of genetic events leading to PI3K/mTOR dysregulation together with the remarkable activity of everolimus in one patient showcases the clinical relevance of this pathway, validates the utility of NGS in this population, and poses everolimus as a novel therapeutic alternative. Several other alterations were found at the genetic and genomic levels, underscoring novel biological processes likely involved during tumor evolution.

Application of mobile internet management in the continuing care of patients after radical prostatectomy

Prostate cancer, a common malignancy in older men, often requires laparoscopic radical prostatectomy, considered the gold standard treatment. However, postoperative complications can significantly impact quality of life and psychological well-being. The emergence of mobile internet health management offers a promising approach for accessible and effective post-discharge care. This study evaluates the effectiveness of mobile internet management in postoperative care for prostate cancer patients, focusing on disease knowledge, psychological well-being, self-care capabilities, and quality of life. From September 2020 to September 2021, prostate cancer patients who underwent radical surgery at our Department of Urology were divided into a control group receiving standard care and an intervention group receiving mobile internet-based care. Patients were followed over six months, with assessments conducted at both 3 and 6 months post-intervention. We evaluated changes in disease knowledge, psychological status (using SAS/SDS scales), self-care ability (via the ESCA scale), and quality of life (measured by SF-36). A total of 112 patients were divided into two groups of 56 each. Repeated measures ANOVA indicated significant improvements in disease knowledge over time, between groups, and in their interaction (P < 0.05). Mastery scores of disease knowledge increased at both 3 and 6 months post-intervention compared to baseline (P < 0.05). The intervention group showed significantly reduced scores on the self-rating depression scale (SDS) and self-rating anxiety scale (SAS) compared to the control group (P < 0.05). Self-care capabilities-including self-directed concept, nursing responsibility, skills, and health knowledge level-also improved, with more pronounced gains in the intervention group (P < 0.05). Quality of life scores in domains such as social function, mental health, vitality, role emotional, bodily pain, role physical, physical function, and general health were higher in the intervention group than in the control group post-intervention (P < 0.05). Mobile internet management significantly enhances postoperative care for prostate cancer patients by improving disease knowledge, psychological well-being, self-care capabilities, and quality of life. These findings support further research to validate long-term benefits and broader application potentials.

Cancer Organoids as reliable disease models to drive clinical development of novel therapies

On September 23-24 (2024) the 6th Workshop IRE on Translational Oncology, titled "Cancer Organoids as Reliable Disease Models to Drive Clinical Development of Novel Therapies," took place at the IRCCS Regina Elena Cancer Institute in Rome. This prominent international conference focused on tumor organoids, bringing together leading experts from around the world.A central challenge in precision oncology is modeling the dynamic tumor ecosystem, which encompasses numerous elements that evolve spatially and temporally. Patient-derived 3D culture models, including organoids, explants, and engineered or bioprinted systems, have recently emerged as sophisticated tools capable of capturing the complexity and diversity of cancer cells interacting within their microenvironments. These models address critical unmet needs in precision medicine, particularly in aiding clinical decision-making. The rapid development of these human tissue avatars has enabled advanced modeling of cellular alterations in disease states and the screening of compounds to uncover novel therapeutic pathways.Throughout the event, distinguished speakers shared their expertise and research findings, illustrating how organoids are transforming our understanding of treatment resistance, metastatic dynamics, and the interaction between tumors and the surrounding microenvironment.This conference served as a pivotal opportunity to strengthen international collaborations and spark innovative translational approaches. Its goal was to accelerate the shift from preclinical research to clinical application, paving the way for increasingly personalized and effective cancer therapies.

A systematic review of peer support interventions to improve psychosocial functioning among cancer survivors: can findings be translated to survivors with a rare cancer living rurally?

BACKGROUND

This study aimed to (1) summarise research on the impact of peer support interventions aimed at improving psychosocial functioning among cancer survivors, and (2) identify key components for developing a support intervention for patients with a rare cancer living in rural, regional or remote areas.

METHODS

A comprehensive search of EMBASE, MEDLINE, PsycINFO, CINAHL, and the Cochrane Library identified papers that examined peer support interventions: (i) for rare cancer patients, or (ii) for those living in rural, regional or remote locations, or (iii) that provided support online or via telehealth. After screening, data on study characteristics, intervention components and impact on psychosocial functioning were extracted. Quality assessment was conducted, and findings were synthesised narratively.

RESULTS

A total of 23 unique studies were included, primarily exploring peer support for middle-aged females with a breast cancer diagnosis. Interventions were online or telephone-based, targeting a range of psychosocial outcomes with significant improvements found for coping abilities and loneliness. The most impactful interventions involved online, group formats facilitated by healthcare professionals. There were limited data on rare cancers and rural populations.

CONCLUSIONS

Few studies have explored peer support interventions for those diagnosed with a rare cancer living in rural, regional or remote areas. Evidence shows mixed impact on psychosocial functioning for cancer survivors, yet promising elements of peer support that can be translated to rare cancer patients living in rural, regional or remote areas.

Bone health management in endocrine-treated patients with prostate cancer: a summary of evidence

OBJECTIVE

This study aimed to gather and assess the most reliable evidence on bone health management in patients undergoing endocrine therapy for prostate cancer, with the goal of informing clinical practice.

DESIGN AND METHODS

Utilizing the '6S' evidence model, a comprehensive literature search was conducted across various sources such as computerized decision support systems, national and international guideline networks, society websites, and databases encompassing clinical decision-making, guidelines, systematic reviews, evidence summaries, and expert consensus. The search spanned from April 2014 to April 2024, with two researchers independently evaluating the quality of the identified literature.

RESULTS

A total of 12 articles were included, comprising 6 clinical guidelines, 5 expert consensus papers, and 1 systematic evaluation. The findings were categorized into risk assessment, prevention, and interventions for osteoporosis and fractures, yielding 26 pieces of best evidence.

CONCLUSION

This study synthesized key evidence on bone health management for prostate cancer patients undergoing endocrine therapy, emphasizing the importance of healthcare professionals utilizing this evidence to develop and implement effective bone health management strategies to mitigate the risk of osteoporosis and fractures.

Nanomedicine mediated thyroid cancer diagnosis and treatment: an approach from generalized to personalized medicine

Thyroid cancer (TC) being the common endocrine malignancy is glooming steadily due to its poor prognosis. The treatment strategies of surgery, radiotherapy, and conventional chemotherapy are providing unsatisfactory output. However, combination therapy can negotiate the worse prognosis to the better, where chemoradiotherapy, radiotherapy with surgery, or dual chemotherapeutic drugs are being glorified. Chemotherapy includes the use of doxorubicin or taxanes generally with platinum-based drugs viz. cisplatin or carboplatin that are administered alone or along with multitarget tyrosine kinase inhibitors viz. Lenvatinib, Sorafenib, Sunitinib, Vandetanib, Pyrazolo-pyrimidine compounds, etc., single target tyrosine kinase inhibitors like Dabrafenib plus Trametinib and Vemurafenib against BRAF, Gefitinib against EGFR, Everolimus against mTOR, vascular disruptors like Fosbretabulin, and immunotherapy with viz. Spartalizumab and Pembrolizumab, are anti-PD-1/PD-L1 molecules. Hence, several trials are currently evaluating the possible beneficial role of combinatorial therapy in TC. Since TC is the outcome of multiple genetic alterations, it necessitates targeting the multiple factors in a single shot. These combination strategies for systemically delivering therapeutic drugs seem feasible only with the help of theranostic. To date, nanoparticle-based drug delivery systems (NDDS) have devoted themselves to diagnosis, bioimaging, imaging-assisted surgery, and therapy with high success rates. The ease of handling hybrid technologies is also selectively admirable. However, in this review, we have summarized the sequential progression of chemotherapeutic drugs to NDDS designed for Personalized Medicine (PM) against TC. Personalized medicine is an ever-growing field that will be explored in future discoveries in biomedicine, particularly cancer theranostics. Hence, our review presents a closer view of NDDS as a personalized treatment for TC. We have also discussed the primary challenges facing NDDS in meeting excellence in PM.

Efficacy and safety of first-line immunotherapy-containing regimens compared with chemotherapy for advanced or metastatic urothelial carcinoma: a network meta-analysis of randomized controlled trials

Introduction

To assess the efficacy and safety of first-line immunotherapy-containing regimens compared with chemotherapy for advanced or metastatic urothelial carcinoma (UC).

Method

A comprehensive search was performed in four databases (Pubmed, Embase, Web of Science, and the Cochrane Library) to identify randomized controlled trials (RCTs) assessing the efficacy of first-line immunotherapy-containing regimens for advanced or metastatic UC. The search encompassed the time span from the inception of the databases to April 23, 2024. A network meta-analysis (NMA) was conducted to assess the rates of progression-free survival (PFS), overall survival (OS), complete response (CR), objective response rate (ORR), and grade ≥ 3 adverse events (AEs).

Results

We conducted a comprehensive analysis of five randomized controlled trials (RCTs) that included a total of 4749 patients. Nine different treatment regimens included in the study were ranked statistically and intuitively using NMA. The top five effective regimens, ranked by OS, were EV + Pembro (1.000), Nivol + Chemo (0.724), Atezo + Chemo (0.610), Durva + Treme (0.558), and Pembro + Chemo (0.530). The top five effective regimens, ranked by PFS, were EV + Pembro (0.999), Nivol + Chemo (0.640), Pembro + Chemo (0.484), Atezo + Chemo (0.373) and Chemo (0.003). The top five effective regimens, ranked by CR, were EV + Pembro (0.969), Nivol + Chemo (0.803), Atezo + Chemo (0.772), Pembro + Chemo (0.472), Durva + Treme (0.449). The top five effective regimens, ranked by ORR, were EV + Pembro (0.995), Nivol + Chemo (0.852), Pembro + Chemo (0.761), Atezo + Chemo (0.623), and Chemo (0.519).

Conclusion

Our results indicated that EV + Pembro as first-line therapy resulted in considerably improved efficacy and safety compared to chemotherapy for advanced or metastatic UC. ICI plus chemotherapy as first-line treatment resulted in a longer PFS, a greater ORR, but no longer OS compared to chemotherapy alone, as well as higher toxicity. ICI alone as first-line therapy provided similar OS and lower toxicity compared to chemotherapy, but lower ORR.

Bibliometric Analysis of Comprehensive Geriatric Assessment from 2004 to 2023

Background

The global aging population necessitates specialized tools for complex geriatric health issues. Comprehensive Geriatric Assessment (CGA) provides multidimensional evaluations of elderly, integrating inputs from various professionals to create individualized care plans. This study aims to visually assess the research trends and hotspots in the field of CGA, review mainstream perspectives in this field, and provide a foundation for future research and treatment.

Methods

Original and review articles related to comprehensive geriatric assessment, published from 2004 to December 2023, were extracted from the Web of Science database. Four different software tools-CiteSpace, VOSviewer, Bibliometrix R package, and the Online Analysis Platform of Bibliometrics-were utilized for this comprehensive analysis.

Results

According to our retrieval strategy, we found a total of 4,411 related literatures. There has been a substantial increase in the research on comprehensive geriatric assessment in the past 20 years. These publications have been cited 157,366 times, with a mean of 35.68 citations per publication. The largest number of publications were from the US, and Italy ranked second (14.98%). Keyword burst and concurrence showed that "randomized trial", "adjuvant chemotherapy" and "breast cancer" were the top 3 most frequently occurring keywords.

Conclusion

Our bibliometric analysis reveals significant growth in CGA research over the past two decades, with a shift from cancer-focused studies to chronic conditions like frailty and sarcopenia. These findings highlight evolving priorities in geriatric care and underscore the need for future research to integrate technological advancements, such as AI, to enhance the precision, scalability, and cost-effectiveness of CGA in diverse settings.

Recurrent paraneoplastic nephrotic syndrome; insights from a Lynch syndrome patient with multiple malignancies

Nephrotic syndrome is a common clinical presentation of glomerulopathy. A glomerulopathy as a paraneoplastic manifestation caused by underlying malignancy is rare. In patients with a solid tumor, membranous nephropathy is the most frequent paraneoplastic glomerulopathy. We present a case of recurrent paraneoplastic nephrotic syndrome caused by minimal change disease in a patient with Lynch syndrome. Over the years, a decrease in creatinine clearance and nephrotic-range proteinuria repeatedly functioned as a warning signal for underlying malignancies; consecutively, a colon adenocarcinoma, renal cell carcinoma and gastric adenocarcinoma were diagnosed. After treatment of the malignancies the nephrotic syndrome resolved without immunosuppressive therapy. Our patient also developed a primary lung carcinoma thrice, which did not cause an exacerbation of the minimal change disease. To further elucidate the mechanism behind the development of this phenomenon, we performed immunohistochemical analysis for vascular endothelial growth factor (VEGF) on the different tumor specimens. We found a high VEGF expression in the gastro-intestinal tumors, whereas the VEGF expression in the lung tumors was low, suggesting an association between VEGF expression and the development of paraneoplastic minimal change disease. This case report not only underlines the importance of considering a malignancy as a cause for (recurrent) nephrotic syndrome, especially in patients with an increased risk of developing malignancies like Lynch syndrome patients, but also suggests a role for VEGF in the pathogenesis of paraneoplastic minimal change disease.

Docetaxel Versus Androgen-Receptor Signaling Inhibitors (ARSI) as Second-Line Therapy After Failure of First-Line Alternative ARSI for the Elderly ≥ 75 Years Old With Metastatic Castration-Resistant Prostate Cancer (mCRPC): A SPARTACUSS-Meet-URO 26 Real-World Study

BACKGROUND

Androgen receptor signalling inhibitors (ARSIs) abiraterone acetate (AA) enzalutamide (Enza), are currently the standard first-line (L1) treatments for metastatic castration-resistant prostate cancer (mCRPC), and docetaxel (D) is reserved as second-line (L2) after ARSI failure. Nonetheless, D use in men ≥ 75 years old is restricted owing to treatment toxicities and patient comorbidities, and a L2 alternative ARSI is frequently used. We aimed to evaluate real-life survival and toxicity outcomes of these elderly patients after failure of L1 ARSI treatment.

MATERIAL AND METHODS

We retrospectively evaluated efficacy and safety in a real-world international cohort of consecutive patients ≥ 75 years old when starting L1 ARSI for mCRPC according to the choice of L2 treatment (D versus alternative ARSI).

RESULTS

Of the 122 identified patients, 57 (46.7%) had received L2 ARSI and 65 (53.3%) L2 D. No difference was found in the L1 overall survival (OS) for the ARSI and D groups (32.8 vs. 30.0 months, respectively; Hazard ratio [HR] = 1.22; 95% CI, 0.77-1.95; P = .40) or in the L2 OS (18.5 vs. 17.8 months, respectively; HR = 1.09; 95% CI, 0.69-1.74; P = .71). No difference was observed for rPFS from L2 (P = .12), although a trend was observed for a numerically improved rPFS on D.

CONCLUSION

Within the limitations of a retrospective design and small population, our study suggests that D or ARSI after failure of L1 alternative ARSI are clinically comparable L2 options for elderly patients with mCRPC.

Cancers with epidemiologic signatures of viral oncogenicity among immunocompromised populations in the United States

BACKGROUND

Immunosuppressed individuals have elevated risk of virus-related cancers. Identifying cancers with elevated risk in people with HIV and solid organ transplant recipients, 2 immunosuppressed populations, may help identify novel etiologic relationships with infectious agents.

METHODS

We used 2 linkages of population-based cancer registries with HIV and transplant registries in the United States. Cancer entities were systematically classified according to site and histology codes. Standardized incidence ratios were used to compare risk in people with HIV and solid organ transplant recipients with the general population. For selected cancer entities, incidence rate ratios were calculated for indicators of immunosuppression within each population.

RESULTS

We identified 38 047 cancer cases in solid organ transplant recipients and 53 592 in people with HIV, yielding overall standardized incidence ratios of 1.66 (95% confidence interval [CI] = 1.65 to 1.68) and 1.49 (95% CI = 1.47 to 1.50), respectively. A total of 43 cancer entities met selection criteria, including conjunctival squamous cell carcinoma (people with HIV standardized incidence ratio = 7.1, 95% CI = 5.5 to 9.2; solid organ transplant recipients standardized incidence ratio = 9.4, 95% CI = 6.8 to 12.6). Sebaceous adenocarcinoma was elevated in solid organ transplant recipients (standardized incidence ratio = 16.2, 95% CI = 14.0 to 18.6) and, among solid organ transplant recipients, associated with greater risk in lung and heart transplant recipients compared with recipients of other organs (incidence rate ratio = 2.3, 95% CI = 1.7 to 3.2). Salivary gland tumors, malignant fibrous histiocytoma, and intrahepatic cholangiocarcinoma showed elevated risk in solid organ transplant recipients (standardized incidence ratio = 3.9,  4.7, and  3.2, respectively) but not in people with HIV. However, risks for these cancers were elevated following an AIDS diagnosis among people with HIV (incidence rate ratio = 2.4, 4.3, and  2.0, respectively).

CONCLUSIONS

Elevated standardized incidence ratios among solid organ transplant recipients and people with HIV, and associations with immunosuppression within these populations, suggest novel infectious causes for several cancers including conjunctival squamous cell carcinoma, sebaceous adenocarcinoma, salivary gland tumors, malignant fibrous histiocytoma, and intrahepatic cholangiocarcinoma.

A diagnostic approach of various urethral diseases using multimodal imaging findings: comprehensive overview

In clinical practice, urethral diseases are not as frequent as conditions affecting other components of the urinary system. Radiological imaging tests, such as retrograde urethrography, CT, MRI, and PET/CT, along with patient history, are crucial for accurately assessing relatively rare urethral lesions. This article aimed to provide a comprehensive overview of urethral lesions, from traumatic changes to neoplasms, and discuss the multimodal imaging findings of various urethral lesions that radiologists should know. To this end, the normal imaging anatomy of the urethra and a step-by-step approach that can be used in clinical practice have been presented to help in the systematic understanding of urethral lesions.

Symptom Burden and Dietary Changes Among Older Adults with Cancer: A Cross-Sectional Study

BACKGROUND

Malnutrition has a direct impact on both the toxicities of cancer therapy and the overall survival of oncological patients. However, its prevalence amongst vulnerable groups such as older patients (age ≥ 65 years) is often underestimated. Screening tools recognizing patients at risk are well established, yet they do not take into account that cancer therapy may lead to changes in dietary habits or that therapy's side effects may negatively influence nutritional status.

METHODS

To close this gap, we combined the validated Nutritional Risk Score 2002 (NRS-2002) and G8 screening tools with short questionnaires addressing diet changes and symptom load and screened 300 cancer inpatients between 12/2022 and 12/2023. Descriptive statistics (Fisher's exact, Student's t-test) as well as heat mapping were applied for data analysis.

RESULTS

Overall, two in three inpatients ≥65 years were at risk for malnutrition, and the majority of patients (87.67%) scored ≤14 points on the G8 and were considered frail. Surprisingly, the symptom complex of oral discomfort was most often mentioned by patients (xerostomia-178/300 patients, loss of appetite: 122/300 patients, dysgeusia: 93/300 patients). Diet changes were also common, with patients mainly avoiding certain foods (122/300 patients) or using dietary supplements (106/300 patients).

CONCLUSIONS

Taken together, older cancer inpatients are frail and have a high risk of malnutrition. Screening should not only consider energy intake but also symptom burden and dietary changes to optimize supportive care.

Novel hormonal agents in men with metastatic castration resistant prostate cancer and reduced performance status: Experiences of a specialized single center

Objectives

Attaining castration resistance in metastatic prostate cancer (mCRPC) represents a pivotal juncture in the progression of the patient's illness and treatment regimen. Within this therapeutic context, novel hormonal agents (NHA) constitute a fundamental component of pharmacological intervention. However, the efficacy of NHA therapy remains uncertain for patients with a compromised general condition, as indicated by an Eastern Cooperative Oncology Group Performance Status (ECOG PS) score of ≥2. Notably, most clinical trials excluded individuals with an ECOG PS ≥2, leaving a gap in our understanding of the potential benefits of NHA therapy for this specific patient cohort.

Methods

We conducted an analysis of fifty-three NHA-naïve men characterized by attaining mCRPC at an ECOG PS of ≥2 subsequent to androgen deprivation monotherapy between 2008 and 2023. Patients were then treated with either NHA or Best Supportive Care (BSC) based on individual decisions. Survival and adverse event (AE) analysis was performed to assess the outcomes of NHA therapy compared to BSC.

Results

Among the patients, 30 (56.6%) received NHA, whereas the remaining 23 (43.4%) choose BSC. No significant differences in baseline characteristics were observed between the NHA and BSC group. Median overall survival (OS) was 9.1 months in the BSC group and 7.0 months in the NHA group, with no significant OS benefits associated with NHA treatment. AEs and severe AEs commonly occurred, but remained indifferent between treatment groups.

Conclusions

Our findings suggest that NHA therapy may confer reduced survival benefits in mCRPC patients with ECOG PS ≥2. While hope for NHA treatment persists, particularly given its oral administration and tolerability, careful consideration and discussion with patients regarding treatment expectations and palliative care goals are warranted in this challenging patient population.

Rapidly Progressive Glomerulonephritis Due to IgA Nephropathy in a Patient With a Large Renal Mass

IgA nephropathy (IgAN) is a common primary glomerulonephritis characterized by the deposition of IgA immune complexes within the glomerular mesangium. IgAN can present with a wide range of clinical manifestations, ranging from asymptomatic hematuria to severe renal disease. This case describes a 67-year-old woman with a history of diabetes mellitus, hypertension, and obesity who presented with acute kidney injury and clinical manifestations of nephrotic syndrome. A renal biopsy confirmed the diagnosis of IgAN. Additionally, imaging studies revealed a large, complex renal mass, raising concerns for renal cell carcinoma. The IgAN was treated with high-dose corticosteroids; however, the patient opted for active surveillance of the renal mass rather than surgical intervention. This case highlights the complex clinical presentation of IgAN and the challenges associated with managing patients with both IgAN and renal mass.

Preoperative geriatric assessment to predict functional outcome after major urologic operations: Results from a multicenter study

INTRODUCTION

Major urological tumor surgery entails a severe risk of unexpected adverse events, persistent functional deterioration, and death in older patients. The Erlangen Index (EI) geriatric assessment tool has previously been shown to predict incomplete functional recovery following major urological tumor surgery in an elderly patient collective. We prospectively evaluated assessment tools including EI in a multicenter setting.

MATERIALS AND METHODS

A total of 340 patients over the age of 65 were assessed prospectively before and after cystectomy, prostatectomy, or renal tumor surgery at three academic centers in Germany and Austria. Endpoints were long-term functional deterioration (Activities of daily living (ADL) measured by Barthel-Index) at day 30 and day 180, and mortality at day 180.

RESULTS

In this study 58 (17.0 %) patients underwent cystectomy, 140 (41.2 %) prostatectomy and 142 (41.8 %) a kidney tumor operation. Mean age was 74.8 years. ADL impairment as a measure of incomplete recovery at day 30 and 180 after surgery were recorded in 47.6 % and 37.4 % of cases, respectively. The EI showed good sensitivity for mortality at day 180 (reference cohort: 85 %, validation center 1: 100 %, validation center 2: 50 %) and for ADL impairment at day 180 (reference cohort 75.4 %, validation center 1 72.3 %, validation center 2 83.3 %).

CONCLUSION

Elderly patients with a poor performance status have a high risk of persistent functional deterioration. Data from this multicenter external validation trial confirms the EI as an accurate and reliable tool to identify patients with high risk of mortality or persistent postoperative functional impairment.

Characteristics and prognosis of testicular mixed teratoma and seminoma

BACKGROUND

To evaluate the association of demographic and clinicopathological characteristics with the survival of patients with testicular mixed teratoma and seminoma (TMTS).

METHODS

The data of 3296 eligible patients with TMTS who underwent surgery between 2010 and 2015 were obtained from the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and cancer-specific survival (CSS) were determined using the Kaplan-Meier survival curves. The association of demographic and clinicopathological characteristics with the OS and CSS of patients with TMTS was assessed using the Cox proportional hazard regression model.

RESULTS

The number of patients with TMTS increased annually. In Kaplan-Meier analyses, TMTS patients with advanced T stage (P < 0.001 for OS and P < 0.001 for CSS), lymph node metastasis (P < 0.001 for OS and P < 0.001 for CSS), distant metastasis (P < 0.001 for OS and P < 0.001 for CSS), no regional lymph node resection (P = 0.003 for OS and P = 0.002 for CSS), large tumor size (P = 0.001 for OS and P = 0.001 for CSS), and LVI (P < 0.001 for OS and P < 0.001 for CSS) exhibited inferior OS and CSS. Moreover, distant metastasis (HR 11.224, P < 0.001; HR 15.817, P < 0.001) and regional lymph node resection (HR 0.425, P = 0.003; HR 0.366, P = 0.004) were identified as independent prognostic factors for OS and CSS in patients with TMTS through multivariable analyses.

CONCLUSIONS

Distant metastasis and lymph node metastasis were deemed important prognostic factors for OS and CSS in patients with TMTS. Therefore, a comprehensive understanding and clinical assessments of these prognostic factors are necessary before tailoring clinical management and treatment plan specified for patients with TMTS.

Recent advances in anticancer mechanisms of molecular glue degraders: focus on RBM39-dgrading synthetic sulfonamide such as indisulam, E7820, tasisulam, and chloroquinoxaline sulfonamide

Synthetic sulfonamide anticancer drugs, including E7820, indisulam, tasisulam, and chloroquinoxaline sulfonamide, exhibit diverse mechanisms of action and therapeutic potential, functioning as molecular glue degraders. E7820 targets RBM39, affecting RNA splicing and angiogenesis by suppressing integrin α2. Phase I studies have demonstrated some stability in advanced solid malignancies; however, further efficacy studies are required. Indisulam causes G1 cell cycle arrest and delays the G1/S transition by modulating splicing through RBM39 degradation via DCAF15. Despite its limited initial efficacy, it shows promise in combination therapies, particularly for hematopoietic malignancies and gliomas. Tasisulam inhibits VEGF signaling, suppresses angiogenesis, and induces apoptosis. Although early trials indicated broad activity, safety concerns have halted its development. Chloroquinoxaline sulfonamide, initially investigated for cell cycle arrest and topoisomerase II inhibition, was discontinued owing to its limited efficacy and toxicity, despite promising initial results. Recent studies revealed the structural interaction of E7820 with DCAF15 and RBM39, although phase II trials on myeloid malignancies have shown limited efficacy. Indisulam is effective against glioblastoma and neuroblastoma, with potential synergy in combination therapies and metabolic disruption. Recent research on tasisulam reveals its potential in cancer therapy by targeting RBM39 degradation through DCAF15-mediated pathways. Understanding these mechanisms could lead to new treatments that affect alternative splicing and improve cancer therapies Overall, although these drugs exhibit promising mechanisms of action, further research is required to optimize their clinical efficacy and safety.

Circulating Blood Biomarkers and Risk of Venous Thromboembolism in Cancer Patients: A Systematic Review and Meta-Analysis

BACKGROUND

 Cancer patients have an increased risk of venous thromboembolism (VTE). Currently, the availability of highly discriminatory prediction models for VTE in cancer patients is limited. The implementation of biomarkers in prediction models might lead to refined VTE risk prediction. In this systematic review and meta-analysis, we aimed to evaluate candidate biomarkers and their association with cancer-associated VTE.

METHODS

 We searched Medline, EMBASE, and Cochrane Central for studies that evaluated biomarkers in adult cancer patients from inception to September 2022. We included studies reporting on VTE after a cancer diagnosis with biomarker measurements performed at a defined time point. Median/mean differences (for continuous measures) and odds ratios (for dichotomous measures) with 95% confidence intervals were estimated and pooled using random-effects models.

RESULTS

 We included 113 studies in the systematic review. Of these, 50 studies were included in the meta-analysis. We identified two biomarkers at cancer diagnosis (factor VIII and time to peak thrombin), three biomarkers pre-chemotherapy (D-dimer, fibrinogen, and mean platelet volume), and one biomarker preoperatively (platelet count) that had significant median or mean differences. Additionally, we found that hemoglobin <100 g/L and white blood count >11 × 109/L were significantly associated with future VTE risk only when measured at cancer diagnosis. Pre-chemotherapy neutrophil-to-lymphocyte ratio ≥3 and preoperative platelet count ≥400 × 109/L were also found to be associated with future VTE risk.

CONCLUSION

 In conclusion, this study identified nine candidate blood biomarkers that may help in optimizing VTE prediction in cancer patients that should be further explored in future studies.

The status quo of global geriatric radiation oncology education: A scoping review

Purpose

To identify potential gaps in geriatric radiation oncology (RO) education worldwide, as measured by geriatric oncology (GO) content within postgraduate RO training program (TP) curricula across 8 focus countries.

Methods and materials

The need for improved education around GO is internationally recognized and is a key strategic priority of the International Society of Geriatric Oncology (SIOG).Two reviewers undertook a systematic scoping review from March to September 2023. Focus countries were selected using predefined selection criteria based on national radiation therapy (RT) service provision, RT access and post-graduate specialty training standards. This review is in accordance with evidence-based curriculum design methodology and represents the initial phase i.e., problem identification and needs assessment.

Results

Overall RO TP and curriculum elements varied by jurisdiction. Common elements included length of training, summative assessments and prerequisite requirements. Considerable variability exists across TPs around identified learning outcomes, content, TP organization, training networks and accreditation.Across 6 TPs, only 2 had any documented GO curriculum content. Of these, only one contained geriatric RO content scoring moderate to high based on accepted quality benchmarks. Outside official RO TPs, there is considerable GO online education content, including face to face courses, peer-reviewed articles, learning materials and resources relevant to RO postgraduate training worldwide. However accessibility to these learning interventions may be region specific and content is not standardized.

Conclusions

As expected, this systematic scoping review has identified significant gaps in GO education within RO TPs worldwide. These findings represent an essential step in the development of evidence-based recommendations for updating standards for GO training within RO training programs and establishing a globally accepted, standardized benchmarks for minimal geriatric RO education. In turn, this will ensure future radiation oncologists are able to deliver a high standard of care to and improve outcomes for older people with cancer.

Cisplatin‑resistant germ cell tumor models: An exploration of the epithelial‑mesenchymal transition regulator SLUG

Germ cell tumors (GCTs) constitute diverse neoplasms arising in the gonads or extragonadal locations. Testicular GCTs (TGCTs) are the predominant solid tumors in adolescents and young men. Despite cisplatin serving as the primary therapeutic intervention for TGCTs, 10‑20% of patients with advanced disease demonstrate resistance to cisplatin‑based chemotherapy, and epithelial‑mesenchymal transition (EMT) is a potential contributor to this resistance. EMT is regulated by various factors, including the snail family transcriptional repressor 2 (SLUG) transcriptional factor, and, to the best of our knowledge, remains unexplored within TGCTs. Therefore, the present study investigated the EMT transcription factor SLUG in TGCTs. In silico analyses were performed to investigate the expression of EMT markers in TGCTs. In addition, a cisplatin‑resistant model for TGCTs was developed using the NTERA‑2 cell line, and a mouse model was also established. Subsequently, EMT was assessed both in vitro and in vivo within the cisplatin‑resistant models using quantitative PCR and western blot analyses. The results of the in silico analysis showed that the different histologies exhibited distinct expression profiles for EMT markers. Seminomas exhibited a lower expression of EMT markers, whereas embryonal carcinomas and mixed GCT demonstrated high expression. Notably, patients with lower SLUG expression had longer median progression‑free survival (46.4 months vs. 28.0 months, P=0.022). In the in vitro analysis, EMT‑associated genes [fibronectin; vimentin (VIM); actin, α2, smooth muscle; collagen type I α1; transforming growth factor‑β1; and SLUG] were upregulated in the cisplatin‑resistant NTERA‑2 (NTERA‑2R) cell line after 72 h of cisplatin treatment. Consistent with this finding, the NTERA‑2R mouse model demonstrated a significant upregulation in the expression levels of VIM and SLUG. In conclusion, the present findings suggested that SLUG may serve a crucial role in connecting EMT with the development of cisplatin resistance, and targeting SLUG may be a putative therapeutic strategy to mitigate cisplatin resistance.

Prevention and management of infectious and tropical diseases in kidney transplant recipients residing in European outermost and overseas territories

BACKGROUND

The European Union encompasses 30 outermost and overseas countries and territories (OCTs). Despite a recent increasing activity of renal transplantation in these territories, many patients still undergo transplantation in continental Europe, with follow-up care coordinated between health professionals from both their transplant center and their home region. Each territory has its unique infectious epidemiology which must be known to ensure appropriate care for kidney transplant recipients (KTRs).

AIMS

This paper proposes a pragmatic approach to optimize pre-transplant check-up and to provide an overview of the specific epidemiological features of each region. It offers practical algorithms to help practitioners in managing infected KTR living in these territories. This work advocates for increased collaborative research among European OCTs.

Avelumab First-Line Maintenance for Locally Advanced or Metastatic Urothelial Carcinoma: Results From the Real-World US PATRIOT-II Study

INTRODUCTION

In JAVELIN Bladder 100, avelumab first-line maintenance (1LM) improved overall survival (OS) and progression-free survival (PFS) in patients with locally advanced/metastatic urothelial carcinoma (la/mUC) without progression following 1L platinum-based chemotherapy (PBC) versus best supportive care. PATRIOT-II describes real-world outcomes with avelumab 1LM.

PATIENTS AND METHODS

This observational, retrospective study of avelumab 1LM in US community/academic centers used medical record data collected from avelumab initiation for ≥12 months to assess survival, safety, and healthcare resource utilization; analyses are descriptive.

RESULTS

The study included 160 patients from 37 centers (median age, 70 years; 77% male). Avelumab 1LM was initiated at a median of 4 weeks (IQR 3-6) after PBC completion. Median follow-up from avelumab 1LM was 16 months (IQR 11-21). At study end, 19.4% of patients continued avelumab; 73.7% had discontinued due to progression, adverse events (AEs), or performance status deterioration. Median PFS and OS from avelumab initiation were 5.4 months (95% CI, 3.8-6.9) and 24.4 months (95% CI, 20.4-28.4), respectively. Grade ≥3 treatment-related AEs (TRAEs) occurred in 15 patients (9.4%); 35 (21.9%) had any-grade immune-related AEs, and 23 (14.3%) received high-dose systemic corticosteroids for AEs. Forty-four patients (27.5%) were hospitalized during the avelumab treatment period, of whom 13 (8.1%) were hospitalized due to TRAEs. Limitations of this study include a small sample size, potential selection bias, and missing/unknown data.

CONCLUSION

These results align with the JAVELIN Bladder 100 clinical trial and other real-world studies, supporting avelumab 1LM use in patients with la/mUC without progression following 1L PBC.

Mesothelioma of the Tunica Vaginalis Testis: Diagnostic and Therapeutic Management. A Comprehensive Review, 1982-2024

BACKGROUND

Mesothelioma of the tunica vaginalis testis (MTVT) is an extremely rare and aggressive cancer. The diagnosis and management of MTVT is complex, and no standard treatment protocol is available.

METHODS

We conducted a systematic literature review from 1 January 1982 to 14 March 2024 using PubMed to collect all the available case reports and case series. A descriptive analysis of patient characteristics with clinical presentation, diagnostic work-up, therapeutic management, and past asbestos exposure was performed. Survival times of patients treated with different therapeutic approaches were evaluated.

RESULTS

Overall, 289 patients with MTVT were included in our analysis. The most common clinical presentations were scrotal/testicular swelling or mass (187 patients, 65%) and the presence of hydrocele (159, 55%). Imaging evaluation, mostly with ultrasonography or CT scan, was reported in two-thirds of cases. Radical surgery (216 patients, 75%) with orchiectomy and, in select cases, hemiscrotectomy and inguinal lymphadenectomy was the most frequent therapeutic approach. A minority of patients (49, 17%) received adjuvant therapy after surgery (radiotherapy, chemotherapy, or a combination of the two), with no evidence of survival improvement.

CONCLUSIONS

No standard guidelines for MTVT are available so far. Radical surgery following accurate radiological staging should be the mainstay of treatment. The role of adjuvant treatments remains undefined. Due to its rarity, MTVT should be treated in referral centers, and patients' data should be collected in a dedicated register in order to improve the knowledge of this exceedingly rare disease and establish optimal diagnostic and therapeutic management.

Descriptive analysis of incidence, demographic characteristics, and survival outcomes of soft-tissue sarcoma of the extremities in Saudi Arabia

Soft-tissue sarcomas are uncommon, aggressive, and histologically heterogeneous, malignant tumors. Soft-tissue tumor types have different age and anatomical site distributions. This study aimed to assess the prevalence and incidence of soft-tissue sarcomas of the extremities to facilitate early diagnosis and intervention in the Kingdom of Saudi Arabia. This retrospective study included all patients diagnosed with primary soft-tissue sarcomas of the extremities and pelvis between January 2006 and December 2015. The data were obtained from the Saudi Cancer Registry. Means and confidence intervals were reported for numerical variables, whereas the frequencies and percentages were reported for categorical variables. The chi-squared test and analysis of variance were used to test the associations between categorical numerical variables. Cox regression analysis was used to determine the hazard ratios for each sarcoma type. Of the 659 patients, 145 (22%) were aged 19-30 years, 365 (55.4%) were men, and 411 (62.4%) had lower limb sarcoma. Most of the tumors (54.3%) were localized. The incidence of sarcoma ranged from 2 to 2.9 cases per one million (average, 2.4 cases per one million). Moreover, liposarcoma was the most commonly diagnosed (n = 135; 20.5%), followed by undifferentiated pleomorphic sarcoma (n = 87; 13.2%). The incidence of soft-tissue sarcomas in the Kingdom of Saudi Arabia were lower than those in Western countries. However, the distribution of soft-tissue sarcoma subtypes was similar to those in other countries. The survival rates in this study highlight the need for continued research and targeted interventions to improve the outcomes of patients with soft-tissue sarcomas, especially those with more aggressive subtypes, such as sarcoma not otherwise specified and rhabdomyosarcoma.

Prostate Cancer: Burden and Correlation with Prostate Specific Antigen Among Screened African Men in Tanzania

Background

Serum prostate-specific antigen (PSA) is a widely used maker for prostate cancer (PCa) screening. However, its correlation with PCa varies, partly due to ethnic differences. This study investigated the correlation between PSA and PCa diagnosis as well as the burden of the disease in the Tanzanian community.

Methods

This community-based PCa screening took place in Northern Tanzania from May 2022 to September 2022, where men aged ≥40 years were involved. Each participant provided 5 milliliters of venous blood for PSA determination. Those with PSA levels >4 ng/mL underwent prostate biopsy. Two pathologists independently evaluated the biopsies. The correlation between PSA and biopsy results was assessed using STATA version 17.0.

Results

The study included 6164 African men with a mean age of 60±11 years. Of these, 912 (14.8%) had PSA >4 ng/mL, and hence 581 (63.7%) underwent prostate biopsy. A total of 179 men (30.8%) were histologically diagnosed with prostatic adenocarcinoma, whereby 46 (25.7%) had Gleason scores 8-9. Among participants with PSA >20 ng/mL, over 2/3 (64.7%) had PCa, rising to nearly 100% at PSA >100 ng/mL. A positive correlation between PSA levels and PCa/aggressive disease was observed. PSA sensitivity decreased with rising levels, hitting 78.2% at >10ng/mL and 24.6% at >100ng/mL, while specificity increased, peaking at 99.8% for >100ng/mL from 73.9% at >10ng/mL. The optimal PSA cut point was >10ng/mL. PSA demonstrated an 84% overall ability to predict PCa and a 71% ability to predict aggressive disease.

Conclusion

This study found a notable presence of intermediate-high grade PCa within the community, suggesting the need for regular screening and management. Moreover, PSA demonstrated clinically useful ability in predicting PCa among African men aged 40 years and older.

Diagnostic trajectories of patients with rare cancer in the Netherlands: results from a nationwide cross-sectional survey

Diagnosing rare cancers is challenging and often leads to prolonged diagnostic trajectories. This study investigated the diagnostic trajectory of patients with rare cancers in The Netherlands. Data from 1541 patients were recruited via patient advocacy in a national online survey on their diagnostic trajectory, such as first general practitioner (GP) consultation to hospital referral and number of hospital visits before final diagnosis. Differences between solid vs. non-solid tumours and EURACAN domains were explored. Diagnostic timelines varied from less than 3 months to over 12 months. Most patients (76.0%) first consulted their GP before going to a hospital. 76.3% of all patients were referred to a hospital within less than 3 months. 32.1% reported receiving an incorrect diagnosis, and 44.6% of them underwent treatment or medication for the (perceived) incorrect diagnosis. Patients with solid vs. non-solid rare cancers trajectories differed significantly for treatment hospital, route to diagnosis, correctness of initial diagnosis, and number of hospital visits before correct diagnosis (all p < 0.001). Patients with neuroendocrine (NET; 21.7%) and endocrine tumours (17.5%) experienced longer GP-to-hospital visit waiting times. Patients with non-solid cancers often received a correct diagnosis after one hospital visit (75%) when compared with patients with solid cancer (2+ = 57.7%). Those with rare skin cancer and non-cutaneous melanoma, head and neck, and thoracic cancer visited multiple hospitals before an accurate diagnosis (56.7%, 53.8%, and 50.0%). Patients with rare cancers face significant challenges with diagnostic delays and inaccuracies. Researching symptom signatures and investing in regional clinical networks might improve diagnostic timelines.

Comprehensive geriatric assessment guided radiotherapy in elderly patients with locally advanced rectal cancer-exploratory results on nonoperative cohort of a multicenter prospective study

BACKGROUND

Chemoradiotherapy (CRT) is the main treatment for elderly patients with non-metastatic rectal cancer who are ineligible for or decline surgery, but the optimal modality remains unclear.

OBJECTIVES

This study was to validate the safety and efficacy of comprehensive geriatric assessment (CGA) guided radiotherapy in older patients.

DESIGN

An exploratory analysis of a single-arm, multicenter, Phase II trial.

METHODS

Patients aged over 70 and diagnosed with rectal cancer were enrolled and evaluated by CGA. CGA-guided radiotherapy was individually conducted in a multidisciplinary setting. Patients in fit, intermediate, and frail groups were scheduled to receive CRT, long-course radiotherapy, and short-course radiotherapy (SCRT) alone respectively. Patients who were unfit for or refused surgery were analyzed for acute toxicities and survival outcomes.

RESULTS

In a total of 109 enrolled patients, 47 individuals who did not undergo surgery were included, with 26, 9, and 12 categorized into fit, intermediate, and frail groups. Only 11 (23.4%) grade 3 or above toxicities were observed overall. Within a median follow-up of 69.0 months, the 3-year overall survival (OS), progression-free survival (PFS), and cancer-specific survival (CSS) rates were 44.3% (95% CI: 32.1%-61.2%), 25.5% (95% CI: 15.7%-41.6%) and 61.0% (95% CI: 47.8%-77.6%) in total. The 5-year OS, PFS, and CSS reached 15.0% (95% CI: 7.4%-30.3%), 14.6% (95% CI: 7.3%-29.4%), and 36.2% (95% CI: 22.0%-59.4%), with no significant difference among the three subgroups. SCRT (p < 0.001) and dose boost (p = 0.045) contributed to lower tumor-related death rates in multiple competing risk regressions.

CONCLUSION

Radiotherapy guided by CGA was effective and well-tolerated in non-surgical elderly patients. SCRT alone seemed to achieve similar clinical outcomes as CRT in corresponding subgroups. However, given the limited size of this study, further investigation in a larger population is still needed for this strategy.

Optimizing Care Across the Continuum for Older Adults with Lung Cancer: A Review

Older adults with lung cancer experience inferior clinical outcomes compared to their younger counterparts. This review provides the scaffolding to address these disparities by delineating (1) the distinct and varied care needs of older adults with lung malignancies, (2) evidence-based measures for identifying subgroups within this population meriting tailored approaches to care, (3) age-specific considerations for the selection of cancer-directed therapy, and (4) opportunities for future work to enhance clinical outcomes and care delivery.

Trends of prostate cancer treatment in Ehime Prefecture, Japan: analysis of a hospital-based cancer registry

BACKGROUND

We previously conducted a retrospective Japanese cohort study of patients who underwent radical prostatectomy (RP) between January 2010 and December 2020 in Ehime Prefecture. This study revealed an increase in the number of RP, but other treatment trends remained unclear. In the current study, we examined prostate cancer treatment in Ehime Prefecture using the hospital-based cancer registry of all designated cancer care hospitals and community cancer care hospitals belonging to the Council of Ehime Cancer Care Hospitals.

METHODS

Trends of prostate cancer were compared by year according to stage and treatment using data from the hospital-based cancer registry between 2011 and 2020.

RESULTS

The number of patients with stage 1 disease increased over time, but the proportion of patients with stage 1 disease among all patients decreased from 65.2% in 2012 to 56.9% in 2020. The number of patients with stage 2 disease also increased, but the proportion of such patients among all patients remained constant. Meanwhile, the proportions of patients with stage 3 or 4 disease increased significantly over time, while that of patients undergoing RP increased from 29.2% in 2011 to 45.7% in 2020 (P < 0.001). The proportion of patients receiving radiotherapy (RT) decreased from 25.8% in 2011 to 17.2% in 2020. The use of hormone therapy (HT) remained unchanged, and the proportion of patients undergoing observation fell from 11.0% in 2011 to 7.0% in 2020. A higher proportion of patients with stage 3 cancer received HT, and RT was more frequently used in stage 3 cancer than in stage 1-2 cancer. The use of HT increased with age.

CONCLUSIONS

The data highlighted differences in prostate cancer stages and treatment over time. This information could be shared with both urologists and radiologists to improve treatment.

Localized Unresectable Thymic Carcinoma Treated with Induction Chemotherapy with Lenvatinib before Radiotherapy: A Case Report

Thymic carcinoma (TC) is a rare malignancy with limited treatment options. Lenvatinib, a novel multitarget kinase inhibitor, has recently been used to treat advanced or metastatic thymic carcinoma that cannot be surgically removed. To date, there have been no reports of lenvatinib being used as induction chemotherapy prior to radiotherapy in cases of localized, unresectable thymic carcinoma. We herein report an 85-year-old Japanese woman with localized unresectable thymic carcinoma who was treated with lenvatinib as induction chemotherapy before undergoing radiotherapy. Our findings suggest that lenvatinib may be a viable option for induction chemotherapy in similar clinical scenarios.

Evaluating nivolumab plus gemcitabine-cisplatin's cost-effectiveness for aUC in China

Aims

Assessing the cost-effectiveness of Nivolumab with Gemcitabine-Cisplatin for Advanced Urothelial Carcinoma (aUC) treatment from the perspective of Chinese payers.

Methods

A Markov model assessed economic outcomes, estimating health outcomes in quality-adjusted life years (QALYs). One-way and probabilistic sensitivity analyses were conducted to assess the impact of uncertainties on the results.

Results

The base-case analysis showed Nivolumab plus Gemcitabine-Cisplatin yielded 0.59 QALYs at an extra cost of $78,780.61, leading to an incremental cost-effectiveness ratios (ICER) of $133,526.46/QALY. One-way sensitivity analysis highlighted Nivolumab's cost as the key factor, while probabilistic sensitivity analysis showed a 0% chance of cost-effectiveness for Nivolumab plus Gemcitabine-Cisplatin in aUC treatment.

Conclusion

Nivolumab plus Gemcitabine-Cisplatin is not cost-effective in the treatment of aUC.

[Deployment of the Icope program in oncogeriatrics]

The World Health Organization recommends the use of the Integrated Care for Older People program to prevent the onset of dependency and enable seniors to age as they wish. In oncogeriatrics, it can be offered before or after the therapeutic project to any autonomous patient in order to monitor their intrinsic capacity. The experience of the Toulouse University Hospital shows the value of this follow-up in oncogeriatrics and the adherence of participants.

Glasgow Prognostic Score and Outcomes in Elderly Head and Neck Cancer Surgery With Free-Flap Reconstruction: A Retrospective Study

Background Determining good candidates for head and neck cancer surgery in elderly patients requires consideration of various factors, such as overall health and social background, yet specific evaluation guidelines are lacking. The Glasgow Prognostic Score (GPS) is a marker used to assess nutritional status and prognosis in cancer patients. Objective This study aims to evaluate the association between the GPS and both the prognosis and postoperative complications in reconstructive surgery cases for head and neck cancer in patients aged 80 and over. Materials and methods A total of 22 patients aged 80 and over who underwent reconstructive surgery in our department between January 2011 and December 2023 were included. Patients were divided into three groups based on their preoperative GPS scores (0, 1, and 2 points). The overall survival was evaluated using the Kaplan-Meier method. The Cox proportional hazards model was used to analyze the association between GPS and prognosis, adjusting for confounders such as malnutrition, primary site, and comorbidities. The association between GPS and perioperative complications classified as Clavien-Dindo grade 3 or higher was also examined. Results The mean age was 82.2 years, and 20 (90%) of the subjects had comorbidities. Higher GPS scores were associated with lower survival rates, and GPS was an independent prognostic factor. There was no significant association between GPS and perioperative complications of grade 3 or higher. Conclusion The GPS is a useful prognostic indicator in elderly patients undergoing reconstructive surgery for head and neck cancer. However, a comprehensive evaluation such as the Geriatric 8, along with more inclusive malnutrition criteria, is recommended for an overall assessment of good candidates for the procedure.
