Efficacy and Safety of Robotic Surgery vs. Open Surgery for Hilar Cholangiocarcinoma: A Comprehensive Review.

Hilar cholangiocarcinoma, a rare and aggressive bile duct malignancy, presents significant challenges in surgical management. Traditionally treated with open surgery, the emergence of robotic surgery has introduced a new dimension to surgical approaches for this condition. This review aims to systematically compare the efficacy and safety of robotic surgery versus open surgery for hilar cholangiocarcinoma. We conducted a comprehensive review of the literature, including clinical studies, case series, and comparative analyses of robotic and open surgical techniques. Data on oncological outcomes, functional recovery, survival rates, complications, and cost-effectiveness were extracted and analyzed to provide a detailed comparison of the two surgical approaches. Robotic surgery offers several potential advantages over open surgery, including reduced intraoperative blood loss, smaller incisions, and shorter recovery times. However, it requires specialized training and has a higher initial cost. Open surgery, while more established and broadly practiced, remains associated with longer recovery periods and higher complication rates. Oncological outcomes, such as R0 resection rates and survival, appear comparable between the two approaches, though robotic surgery may offer improvements in functional recovery and postoperative quality of life. Both robotic and open surgery have their merits in the treatment of hilar cholangiocarcinoma. Robotic surgery presents promising benefits in terms of reduced invasiveness and improved recovery, while open surgery continues to be a reliable and well-established option. The choice of surgical approach should be guided by patient-specific factors, surgeon expertise, and institutional resources. Further research is needed to refine surgical techniques and establish long-term outcomes, which will aid in optimizing treatment strategies for this challenging malignancy.

Oncological outcomes of minimally invasive surgery in non-endometrioid endometrial Cancer patients with varying prognostic risks: a retrospective cohort study based on the ESGO/ESTRO/ESP 2020 guidelines.

BACKGROUND: Non-endometrioid endometrial carcinomas (NEEC) are characterized by their rarity and adverse prognoses. This study evaluates the outcomes of open versus minimally invasive surgery (MIS) in NEEC patients stratified by prognostic risks according to the 2020 ESGO-ESTRO-ESP risk classification guidelines. METHODS: A retrospective analysis was performed on 99 NEEC patients who underwent initial surgery at Fujian University Cancer Hospital. Patients were categorized into two groups: those undergoing MIS and those undergoing open surgery. We compared disease-free survival (DFS) and overall survival (OS) between these groups. Cox regression analysis was employed to identify risk factors for DFS, which were further validated via bootstrap statistical methods. RESULTS: The study included 31 patients in the MIS group and 68 in the open surgery group. The demographics and clinical characteristics such as age, body mass index, comorbidities, histological subtypes, and FIGO stage were similar between groups (P > 0.05). The MIS group experienced ten recurrences (1 vaginal, 2 lymph nodes, 7 distant metastases), whereas the open surgery group had seven recurrences (1 vaginal, 3 lymph nodes, 1 pelvis, 2 distant metastases), yielding recurrence rates of 10.3% versus 25.6% (P = 0.007). Besides lymphovascular space invasion (LVSI), surgical approach was also identified as an independent prognostic factor for DFS in high-risk patients (P = 0.037, 95% CI: 1.062-7.409). The constructed nomogram demonstrated a robust predictive capability with an area under the curve (AUC) of 0.767. Survival analysis for high- and intermediate-risk patients showed no significant differences in OS between the two groups (Phigh risk = 0.275; Pintermediate-risk = 0.201). However, high-risk patients in the MIS group exhibited significantly worse DFS (P = 0.001). CONCLUSION: This investigation is the inaugural study to assess the impact of surgical approaches on NEEC patients within the framework of the latest ESGO-ESTRO-ESP risk classifications. Although MIS may offer clinical advantages, it should be approached with caution in high-risk NEEC patients due to associated poorer DFS outcomes.

Influence of Anesthetic Techniques on Colorectal Cancer Recurrence: A Comprehensive Review.

Colorectal cancer is a leading cause of cancer-related morbidity and mortality worldwide, with a significant risk of recurrence following surgical treatment. Emerging evidence suggests that perioperative factors, particularly anesthetic techniques, may influence cancer recurrence rates. This comprehensive review aims to critically analyze the impact of various anesthetic techniques on colorectal cancer recurrence. We explore the distinct immunomodulatory and inflammatory effects of general, regional, and combined anesthetic approaches and their potential influence on tumor biology. The review synthesizes findings from clinical studies, experimental research, and theoretical models, highlighting the differential impact of anesthetic choices on long-term oncological outcomes. By examining recurrence rates, immune responses, and inflammatory markers associated with different anesthetic techniques, this review provides a holistic understanding of the role of anesthetic management in colorectal cancer surgery. Our findings suggest that anesthetic techniques can modulate the immune and inflammatory responses in ways that may affect tumor recurrence, underscoring the need for further research to optimize anesthetic protocols. The review offers clinical recommendations based on current evidence and identifies gaps in knowledge, proposing directions for future investigations. This comprehensive analysis aims to inform clinical practice and guide future research, ultimately improving long-term outcomes for colorectal cancer patients.

Follow-up strategies after trimodal treatment for muscle-invasive bladder cancer: a systematic review.

PURPOSE: Optimal follow-up strategies following trimodal treatment for muscle invasive bladder cancer play a crucial role in detecting and managing relapse and side-effects. This article provides a comprehensive summary of the patterns and risk factors of relapse, functional outcomes, and follow-up protocols. METHODS: A systematic literature search on PubMed and review of current guidelines and institutional follow-up protocols after trimodal therapy were conducted. RESULTS: Out of 200 identified publications, 43 studies (28 retrospective, 15 prospective) were selected, encompassing 7447 patients (study sizes from 24 to 728 patients). Recurrence rates in the urinary bladder varied between 14-52%; 3-16% were muscle-invasive while 11-36% were non-muscle invasive. Nodal recurrence occurred at 13-16% and distant metastases at 15-35%. After 5 and 10 years of follow-up, around 60-85% and 45-75% of patients could preserve their bladder, respectively. Various prognostic risk factors associated with relapse and inferior survival were proposed, including higher disease stage (> c/pT2), presence of extensive/multifocal carcinoma in situ (CIS), hydronephrosis, multifocality, histological subtypes, incomplete transurethral resection of bladder tumor (TURBT) and incomplete response to radio-chemotherapy. The analyzed follow-up guidelines varied slightly in terms of the number, timing, and types of investigations, but overall, the recommendations were similar. CONCLUSION: Randomized prospective studies should focus on evaluating the impact of specific follow-up protocols on oncological and functional outcomes following trimodal treatment for muscle-invasive bladder cancer. It is crucial to evaluate personalized adaption of follow-up protocols based on established risk factors, as there is potential for improved patient outcomes and resource allocation.

The effect of pulmonary rehabilitation on quality of life and functional capacity after chemotherapy in patients with small cell lung cancer.

OBJECTIVE: This study aimed to investigate the effect of pulmonary rehabilitation on quality of life during the survival period in individuals with small cell lung cancer. METHODS: Thirty-six patients with a diagnosis of small cell lung cancer (SCLC), who completed chemotherapy treatment and were in the survival period, were included in the study. A pulmonary rehabilitation program was applied to individuals at 40-70% of submaximal heart rate, 3 days a week for 8 weeks. The pulmonary rehabilitation program will consist of warm up, breathing exercises, gait training, aerobic exercises, and cool down exercises. Demographic information, walking distance, and presence of dyspnea were questioned. Inspiration/expiration difference was evaluated. Vital signs were evaluated before each session. Quality of life was assessed with the Cancer-Specific Developed Quality of Life Scale (EORTC-QLQ-C30). RESULTS: Of the patients, 80% (36 people) completed the entire 8-week program. The mean age of the individuals was 51.78 ± 10.23. In the evaluation made at the end of the rehabilitation program, it was observed that the walking distance of the individuals increased significantly. Inspiration of individuals' expiratory difference increased by an average of 2.01 ± 0.40 cm. Improvement was found in the sub-parameters of quality of life (p < 0.05). SIGNIFICANCE OF RESULTS: The participants with small cell lung cancer had decreased quality of life due to long-term immobilization, surgery, hospitalization times, side effects of chemotherapy treatment, and other problems. Regular exercise programs can provide an increase in the individual's pulmonary functions. Individual-specific pulmonary rehabilitation programs have important contributions to the quality of life in SCLC on the survival period, and it has shown that this study can guide physiotherapists and physicians working in oncological rehabilitation and pulmonary rehabilitation.

Survival, Surgical, and functional outcomes of transoral laser microsurgery for cT1-T3 supraglottic laryngeal Cancers: A systematic review.

BACKGROUND: This review aimed to investigate the surgical, functional, and oncological outcomes of transoral laser microsurgery supraglottic laryngectomy (TOLM-SGL) for cT1-T3 laryngeal cancers. METHODS: PubMed, Scopus, and Cochrane Library were searched by two independent investigators for studies investigating the surgical, functional, and oncological outcomes of TOLM-SGL using the PRISMA statements. A bias analysis was carried out with MINORS. RESULTS: Twenty-four studies were included (937 patients), including 206 (25.9 %) cT1, 467 (58.7 %) cT2, and 123 (15.4 %) cT3 cases. Most patients were cN0 (63.9 %). The mean hospital stay of TOLM was 10.1 days. Aspiration (5.5 %), and bleeding (5.3 %) were the most prevalent complications. The laryngeal preservation rate was 93.7 %. Temporary tracheotomy was performed in 18.0 % of patients, with a mean time of decannulation of 6.8 days. A feeding tube was placed in 59.9 % of patients. The oral diet restarted after 6.4 days. Definitive gastrostomy was necessary in 2.4 % of cases. The 5-year OS and DFS were 70.1 % and 82.0 %, respectively. Distant metastasis, local, and regional recurrence occurred in 4.6 %, 11.6 %, and 5.1 % of patients. There was an important heterogeneity between studies for inclusion criteria, patient profiles, TOLM indications, and details of surgical, functional, and oncological outcomes. CONCLUSION: TOLM supraglottic laryngectomy is a safe, and effective procedure associated with adequate functional, surgical, and oncological outcomes. Future studies are needed to define the place of TOLM in advanced LSCC; the role and timing of concomitant bilateral neck dissection, the indications of tracheotomy and feeding tube.

The Difficult Airway in Patients with Cancer.

PURPOSE OF REVIEW: The goal of this review is to provide an overview of difficult airway management in the cancer population. RECENT FINDINGS: Difficult airways can be unanticipated; however, several anatomical and physiological features may predict difficult airway management, with several specific for the cancer patient population. New technologies and techniques for airway management, including non-invasive oxygenation, and even the utilization of ECMO, have led to better outcomes and decreased morbidity. Furthermore, the incorporation of multidisciplinary airway teams has helped reduce morbidity associated with predicted and known difficult airways. Cancer patients may exhibit or develop anatomic and physiologic features that may predispose them to difficulty with airway management. As our technologies for airway management continue to advance, as well as further commitment to more interdisciplinary collaboration, difficult airway management in the cancer population will continue to become safer.

Intraoperative end-tidal carbon dioxide levels are not associated with recurrence-free survival after elective pancreatic cancer surgery: a retrospective cohort study.

Background: Intraoperative end-tidal carbon dioxide concentrations (EtCO2) values are associated with recurrence-free survival after colorectal cancer surgery. However, it is unknown if similar effects can be observed after other surgical procedures. There is now evidence available for target EtCO2 and its relation to surgical outcomes following pancreatic cancer surgery. Methods: In this single-center, retrospective cohort study, we analyzed 652 patients undergoing elective resection of pancreatic cancer at Heidelberg University Hospital between 2009 and 2016. The entire patient cohort was sorted in ascending order based on mean intraoperative EtCO2 values and then divided into two groups: the high-EtCO2 group and the low-EtCO2 group. The pre-specified primary endpoint was the assessment of recurrence-free survival up to the last known follow-up. Cardiovascular events, surgical site infections, sepsis, and reoperations during the hospital stay, as well as overall survival were pre-specified secondary outcomes. Results: Mean EtCO2 was 33.8 mmHg ±1.1 in the low-EtCO2 group vs. 36.8 mmHg ±1.9 in the high-EtCO2 group. Median follow-up was 2.6 (Q1:1.4; Q3:4.4) years. Recurrence-free survival did not differ among the high and low-EtCO2 groups [HR = 1.043 (95% CI: 0.875-1.243), log rank test: p = 0.909]. Factors affecting the primary endpoint were studied via Cox analysis, which indicated no correlation between mean EtCO2 levels and recurrence-free survival [Coefficient -0.004, HR = 0.996 (95% CI:0.95-1.04); p = 0.871]. We did not identify any differences in the secondary endpoints, either. Conclusions: During elective pancreatic cancer surgery, anesthesiologists should set EtCO2 targets for reasons other than oncological outcome until conclusive evidence from prospective, multicenter randomized controlled trials is available.

Cancer characteristics in patients with schizophrenia: a 25-year retrospective analysis.

Schizophrenia is associated with higher cancer-related mortality, perhaps due to delayed diagnosis and limited access to treatment. The study aimed to compare patients diagnosed with cancer with and without schizophrenia to determine whether these groups differ in terms of oncological variables and survival outcomes. This was a retrospective, observational cohort study that included 30.990 patients diagnosed with cancer between 1997 and 2021. We performed univariate and bivariate analyses for the sociodemographic and clinical variables, and constructed Kaplan-Meier survival curves and used the log-rank test to perform the comparisons. All variables were compared for each cancer type. One hundred and sixty-two (0.52 %) patients had a confirmed diagnosis of schizophrenia (ICD-9 criteria). The mean age at diagnosis was significantly lower in the schizophrenia group. A significantly higher proportion of the schizophrenia group was diagnosed with cancer through the emergency department and a lower percentage through scheduled appointments. A smaller percentage of patients in the schizophrenia group received radical treatment for cancer. The mortality rate was higher in the schizophrenia group and median survival was lower. These findings suggest that cancer patients with schizophrenia have worse outcomes than patients without schizophrenia in terms of oncological variables and survival.

Features of Metabolites and Biomarkers in Inflammatory and Infectious Complications of Childhood Cancers.

Background: In the treatment of oncological diseases in children, the search for opportunities for the earlier detection of complications to improve treatment results is very important. Metabolomic studies are actively conducted to stratify different groups of patients in order to identify the most promising markers. Methods: Three groups of patients participated in this study: healthy children as a control group (n = 18), children with various malignant oncological diseases (leukemia, lymphoma, nephroblastoma, ependymoma, etc.) as patients (n = 40) without complications, and patients (n = 31) with complications (inflammatory and infectious). The mitochondrial metabolites (succinic and fumaric acids); biomarkers related to inflammation such as C-reactive protein (CRP), procalcitonin (PCT), and presepsin (PSP); and sepsis-associated aromatic metabolites, such as phenyllactic (PhLA), hydroxyphenyllactic (p-HPhLA), and hydroxyphenylacetic acids (p-HPhAA), were identified. Results: It was found that children with malignant oncological diseases had profound metabolic dysfunction compared to healthy children, regardless of the presence of systemic inflammatory response syndrome (SIRS) or sepsis. The prognostic ability of procalcitonin and presepsin for detecting sepsis was high: AUROC = 0.875, cut-off value (Youden index) = 0.913 ng/mL, and AUROC = 0.774, with cut-off value (Youden index) of 526 pg/mL, respectively. Conclusions: A significant increase in aromatic microbial metabolites and biomarkers in non-survivor patients that is registered already in the first days of the development of complications indicates the appropriateness of assessing metabolic dysfunction for its timely targeted correction.

Active surveillance for low-risk prostate cancer with high tumor burden at biopsy: lessons learned from a contemporary radical prostatectomy cohort.

INTRODUCTION: To investigate whether initial tumor burden at biopsy could predict adverse features after radical prostatectomy (RP) in International Society of Urological Pathology (ISUP) 1 prostate cancer (PCa) patients. METHODS: This retrospective study was conducted in six referral centers. The cohort included patients with ISUP 1 PCa at systematic and MRI-targeted biopsy. We defined a high tumor burden at biopsy if ≥ 20% of cores were positive. The endpoint of the study was adverse features at RP, defined as ≥ pT3a stage and/or N1 and/or ISUP ≥ 3. Sensitivity analyses were performed to assess associations between different thresholds on biopsy (percentage of positive cores [PPC] ≥ 25%, ≥ 33%, ≥ 50%, bilateral positivity and positive cores > 3) and adverse features. As the number of targeted biopsies sampled may influence the number of positive cores, we used a virtual biopsy model in which all targeted biopsy results were interpreted as a single targeted biopsy. RESULTS: A total of 312 contemporary patients were included. At final pathology, 99 patients (32%) had adverse features. In multivariate logistic regression analysis, there was no statistical association between PPC > 20% and adverse features (OR = 1.22; 95%CI:0.69-2.22, p = 0.5). In sensitivity analysis, tumor burden at biopsy was not associated with the risk of adverse features, regardless of the definition used (all p > 0.05). When we considered a unique virtual targeted biopsy, tumor burden remained not associated with adverse features (all p > 0.05). CONCLUSIONS: ISUP 1 PCa tumor burden at biopsy did not predict adverse features in this study, suggesting that it should not be used alone as an exclusion criterion when assessing eligibility for active surveillance.

Increased Distress in Neurooncological Patients, a Monocentric Longitudinal Study: When to Screen Which Patient?

OBJECTIVE: Neurooncological patients are well-known to experience an increased psycho-oncological burden with a negative impact on distress, therapy adherence, quality of life, and finally survival. But still, psycho-oncological screening and support is rare, with ongoing discussion about specific screening time points and impact factors. Therefore, we analysed the psycho-oncologic treatment demand at specific disease-related time points throughout therapy. METHODS: In this longitudinal, prospective, single-centre study, patients with malignant brain tumours were screened for increased distress (using the Distress Thermometer), anxiety, depression (Hospital Anxiety and Depression Scale questionnaire), and health-related quality of life interference (EORTC QLQ C30-BN20 questionnaire) at specific longitudinal time points during therapy. The results were correlated with sociodemographic and clinical data. RESULTS: From 2013 to 2017, 2500 prospective screening data points from 512 malignant brain tumour patients were analysed. DT was identified as a significant predictor for psycho-oncological treatment demand (p < 0.001). Particularly significant time points concerning psycho-oncological burden were primary diagnosis and tumour recurrence. Next to these known factors, here, patients < 65 years old and female patients (p = 0.018 and p = 0.017) reflected increased screening results, whereas partnership and professional activity (p = 0.043; p = 0.017) were identified as contributing factors to a significantly decreased treatment demand. CONCLUSIONS: The increased need for psycho-oncological support for neurooncological patients is underlined. Psycho-oncological support should particularly be offered at the time points of primary diagnosis and tumour recurrence. To support the positive effect of caregivers, they should be involved at an early stage.

Factors Influencing Outcomes and Survival in Anal Cancer.

BACKGROUND: We aim to ascertain prognostic factors in the current management of anal cancer within this study. METHODS: We reviewed the management and outcomes of anal cancer cases over a seven-year period, inclusive (2016-2023). The primary objectives were to assess the demographic characteristics, clinical presentation, and outcomes of all anal cancer patients within our institution. Kaplan-Meier survival analysis was used to estimate survival differences between cohorts, with statistical significance determined using log-rank testing. Cox proportional hazards regression was utilised to identify prognostic factors. Cox regression hazard ratios were reported along with confidence intervals and p-values. RESULTS: The median follow-up time for the study was 29.8 months. Seventy-five patients with anal cancer were included in this study, with 88% (66/75) being squamous cell carcinoma (SCC) and the majority having regional disease (82.7% (62/75)). The median age at diagnosis was 63.4 years (36-94). There was a female preponderance (57.3% (43/75)). In total, 84% (63/75) underwent definitive chemoradiation (dCRT), with 7/63 (11.1%) requiring a salvage abdomino-perineal resection (APR) for residual or recurrent disease. Adverse prognostic indicators include those with T4 disease hazard ratio = 3.81, (95% CI 1.13-12.83, * p = 0.04), poorly differentiated tumour disease HR = 3.37, (95% CI 1.13-10.02, * p = 0.04), having N2 nodal status HR = 5.03, (95% CI 1.11-22.8, * p = 0.04), and having metastatic disease at diagnosis HR = 5.8, (95% CI 1.28-26.42, * p = 0.02). CONCLUSION: Presenting characteristics including stage, nodal, and differentiation status remain key prognostic indicators in those diagnosed with anal malignancy.

Comparative Efficacy and Long-Term Oncological Safety of Extended Right Hemicolectomy Versus Left Colectomy for Splenic Flexure Adenocarcinoma: A Systematic Review and Meta-Analysis.

BACKGROUND: Splenic flexure adenocarcinoma poses unique challenges in surgical management due to its location and lymphatic drainage. This study compared the efficacy and oncological safety of extended right hemicolectomy (ERC) and left colectomy (LC) for treating this condition. METHODS: This study followed the PRISMA and AMSTAR 2 guidelines. Key outcomes included postoperative mortality, morbidity, severe complications, operative results, pathological findings (R0 resection, lymph nodes), and oncological results (overall survival and disease-free survival at 3 and 5 years). RESULTS: Twelve non-randomised studies were included involving 1710 patients (713 ERC group, 997 LC group). The analysis showed that ERC was associated with more lymph nodes and a lower conversion rate. However, there were no significant differences between ERC and LC in terms of mortality, morbidity, severe complications, anastomotic leak, wound infection, ileus, reoperation, R0 resection, hospital stay, and overall and disease-free survival rates. CONCLUSIONS: ERC and LC are comparable in terms of postoperative and long-term oncological outcomes for splenic flexure adenocarcinoma, with ERC potentially producing a higher lymph node harvest rate and a lower conversion rate. ERC could be suggested for a better stage of the disease and when the surgical team considers the laparoscopic approach.

Genetic polymorphism in untranslated regions of PRKCZ influences mRNA structure, stability and binding sites.

BACKGROUND: Variations in untranslated regions (UTR) alter regulatory pathways impacting phenotype, disease onset, and course of disease. Protein kinase C Zeta (PRKCZ), a serine-threonine kinase, is implicated in cardiovascular, neurological and oncological disorders. Due to limited research on PRKCZ, this study aimed to investigate the impact of UTR genetic variants' on binding sites for transcription factors and miRNA. RNA secondary structure, eQTLs, and variation tolerance analysis were also part of the study. METHODS: The data related to PRKCZ gene variants was downloaded from the Ensembl genome browser, COSMIC and gnomAD. The RegulomeDB database was used to assess the functional impact of 5' UTR and 3'UTR variants. The analysis of the transcription binding sites (TFBS) was done through the Alibaba tool, and the Kyoto Encyclopaedia of Genes and Genomes (KEGG) was employed to identify pathways associated with PRKCZ. To predict the effect of variants on microRNA binding sites, PolymiRTS was utilized for 3' UTR variants, and the SNPinfo tool was used for 5' UTR variants. RESULTS: The results obtained indicated that a total of 24 variants present in the 3' UTR and 25 variants present in the 5' UTR were most detrimental. TFBS analysis revealed that 5' UTR variants added YY1, repressor, and Oct1, whereas 3' UTR variants added AP-2alpha, AhR, Da, GR, and USF binding sites. The study predicted TFs that influenced PRKCZ expression. RNA secondary structure analysis showed that eight 5' UTR and six 3' UTR altered the RNA structure by either removal or addition of the stem-loop. The microRNA binding site analysis highlighted that seven 3' UTR and one 5' UTR variant altered the conserved site and also created new binding sites. eQTLs analysis showed that one variant was associated with PRKCZ expression in the lung and thyroid. The variation tolerance analysis revealed that PRKCZ was an intolerant gene. CONCLUSION: This study laid the groundwork for future studies aimed at targeting PRKCZ as a therapeutic target.

Return to Intended Oncological Therapy: State of the Art and Perspectives.

PURPOSE OF THE REVIEW: Despite advances in surgical procedures, cancer recurrence still affects a substantial proportion of patients for whom surgery is considered a curative therapy. This review aims to provide a comprehensive overview of RIOT, addressing its definition, influencing factors, and clinical implications. FINDINGS: RIOT can be defined as a continuous variable as the time from surgery to initiation of adjuvant therapies or categorically as whether patients can successfully receive adjuvant therapies or not. Factors influencing RIOT are age, sex, socioeconomic status, access to healthcare, physical performance and comorbidities, and quality of anesthesia and surgical care. Adjuvant therapies such as chemotherapy, radiotherapy, and immunotherapy are often administered to reduce the risk of recurrence after surgery and improve survival. Return to intended oncologic therapy (RIOT) has emerged as a promising outcome metric reflecting patients' functional recovery after surgery and their ability to receive adjuvant therapies.

Newly established borderline resectable 1 (BR1) category is one of the favorable candidates for selecting the use of multidisciplinary combination therapy in patients with advanced hepatocellular carcinoma treated with systemic therapy.

BACKGROUND: The aim of this study was to evaluate the newly established oncological criteria of resectability of hepatocellular carcinoma (HCC) for selecting suitable candidates for systemic and combination therapy. METHODS: The data of 156 consecutive HCC patients with intrahepatic target nodules who had initially received systemic therapy (lenvatinib and atezolizumab plus bevacizumab) were reviewed. The patients were classified into three groups according to the novel oncological criteria for resectability (R, resectable; BR1, borderline resectable 1; and BR2, borderline resectable 2). The prognostic ability and clinical utility for selecting this population to receive combined use of multiple systemic sequential and locoregional therapy was then evaluated. Combined use of systemic sequential therapy with more than two agents and locoregional treatment was defined as multidisciplinary combination therapy (MCT), while systemic sequential therapy only and repeated locoregional treatment was defined as a single treatment procedure (STP). RESULTS: Patients classified as R and BR1 had significantly better overall survival (OS) compared with BR2 (R vs. BR2, p = 0.012; BR1 vs. BR2, p = 0.004). However, there was no significant difference between R and BR1 (p = 1.000), in spite of significantly worse oncological status in the BR1 patients. Following a R0 resection and MCT, the BR1 patients had significantly better OS compared with those receiving STP or no additional treatment (median OS, not reached vs. 25.2 months and 20.1 vs. 11.3 months, respectively; p = 0.034). CONCLUSIONS: In patients with advanced HCC with intrahepatic target nodules the BR1 category is one of the favorable candidates for selecting those to be treated with MCT strategies.

Robot-assisted nephroureterectomy: surgical and mid-term oncological outcomes in over 1100 patients (ROBUUST 2.0 collaborative group).

OBJECTIVE: To analyse surgical, functional, and mid-term oncological outcomes of robot-assisted nephroureterectomy (RANU) in a contemporary large multi-institutional setting. PATIENTS AND METHODS: Data were retrieved from the ROBotic surgery for Upper tract Urothelial cancer STtudy (ROBUUST) 2.0 database, an international, multicentre registry encompassing data of patients with upper urinary tract urothelial carcinoma undergoing curative surgery between 2015 and 2022. The analysis included all consecutive patients undergoing RANU except those with missing data in predictors. Detailed surgical, pathological, and postoperative functional data were recorded and analysed. Oncological time-to-event outcomes were: recurrence-free survival (RFS), metastasis-free survival (MFS), cancer-specific survival (CSS), and overall survival (OS). Survival analysis was performed using the Kaplan-Meier method, with a 3-year cut-off. A multivariable Cox proportional hazard model was built to evaluate predictors of each oncological outcome. RESULTS: A total of 1118 patients underwent RANU during the study period. The postoperative complications rate was 14.1%; the positive surgical margin rate was 4.7%. A postoperative median (interquartile range) estimated glomerular filtration rate decrease of -13.1 (-27.5 to 0) mL/min/1.73 m2 from baseline was observed. The 3-year RFS was 59% and the 3-year MFS was 76%, with a 3-year OS and CSS of 76% and 88%, respectively. Significant predictors of worse oncological outcomes were bladder-cuff excision, high-grade tumour, pathological T stage ≥3, and nodal involvement. CONCLUSIONS: The present study contributes to the growing body of evidence supporting the increasing adoption of RANU. The procedure consistently offers low surgical morbidity and can provide favourable mid-term oncological outcomes, mirroring those of open NU, even in non-organ-confined disease.

Blood-, Tissue- and Urine-Based Prognostic Biomarkers of Upper Tract Urothelial Carcinoma.

Upper tract urothelial carcinoma (UTUC) is a rare but aggressive neoplasm. Currently, there are few reliable and widely used prognostic biomarkers of this disease. The purpose of this study was to assess the prognostic value of blood-, tissue- and urine-based biomarkers in patients with UTUC. A comprehensive literature search was conducted using the PubMed, Cochrane and Embase databases. Case reports, editorials and non-peer-reviewed literature were excluded from the analysis. As a result, 94 articles were included in this review. We evaluated the impact of 22 blood-based, 13 tissue-based and 4 urine-based biomarkers and their influence on survival outcomes. The neutrophil-lymphocyte ratio, albumin, C-reactive protein, De Ritis ratio, renal function and fibrinogen, which are currently mentioned in the European Association of Urology (EAU) guidelines, are well researched and most probably allow for a reliable prognosis estimate. However, our review highlights a number of other promising biomarkers that could potentially predict oncological outcomes in patients with UTUC. Nonetheless, the clinical value of some prognostic factors remains uncertain due to the lack of comprehensive studies.
