Purpose: To describe the molecular profile of a real-world cohort of patients with metastatic urothelial carcinoma (mUC) and to evaluate the benefit of next-generation sequencing (NGS) panels in guiding therapy in patients with mUC and the outcomes of DNA-matched treatments recommended by a multidisciplinary molecular tumor board (MMTB).

Methods: This was a single-center analysis of a real-world cohort of adult patients with mUC included in an ongoing trial that aimed to evaluate the clinical utility of NGS for solid tumors. Genomic analysis was performed for each patient, most of them using the Ion Torrent Oncomine Focus Assay. Genomic results were discussed during MMTB meetings.

Results: We included 43 patients with mUC treated with platinum-based combinations and immunotherapy. Twenty-five patients (58.1%; 95% CI 43.4-72.9) had at least one tumor pathogenic alteration. The MMTB classified 16 (48.5%) of the 33 tumor pathogenic alterations found in our real-world cohort of mUC patients as ESCAT I, which is the maximum grade of actionability. After excluding patients who were not candidates for targeted therapies, the MMTB provided guidance on matched therapy for seven patients. Among these patients, three achieved a partial response for an overall response rate of 42.9%, a median progression-free survival of 7.3 months (95% CI 6.7-7.9) and a median overall survival of 10.9 months (95% CI 2.4-19.5).

Conclusions: We recommend that all patients with mUC undergo NGS at diagnosis given the high percentage of patients with pathogenic alterations in our real-world cohort and the efficacy data of patients treated with targeted therapies.

Background: The association between serum folate concentrations and the mortality of cancer remains unclear. We aim to investigate the association of serum folate concentrations with all-cause and cause-specific mortality among American adults with cancer.

Methods: This cohort study included 4535 patients with cancer from National Health and Nutrition Examination Survey (NHANES) 1999 to 2016 and NHANES III (1988-1994). Death outcomes were ascertained by linkage to National Death Index records through 31 December 2019. Cox proportional hazards model and two-piecewise Cox proportional hazards model were used to calculate hazard ratios and 95% confidence intervals for the associations between folate concentrations and the risk of mortality.

Results: During a median follow-up of 37,792 person-years, there were 1998 all-cause deaths and 616 cancer deaths. Non-linear and L-shaped associations were observed between serum folate concentrations and the risk of all-cause and cancer mortality among patients with cancer. Notably, the mortality rates reached a plateau at 23.7 ng/mL for all-cause mortality and 23.57 ng/mL for cancer mortality. When folate levels fell below these thresholds, the risk of all-cause and cancer mortality decreased by approximately 2.1% (HR 0.979; 95% CI 0.969-0.989) and 3.6% (HR 0.964; 95% CI 0.948-0.981), respectively, with each unit increase in the folate concentration up to the thresholds.

Conclusion: Our study reveals that low serum folate concentrations are linked to an elevated risk of cancer mortality among individuals with cancer within a certain range and supplementation of folate in cancer patients to achieve specific serum folate level threshold (23.7 ng/mL) might reduce the risk of cancer mortality.

Background: Hepatocellular carcinoma (HCC) is a highly aggressive tumor associated with significant morbidity and mortality rates. Combination therapy with immune checkpoint inhibitors (ICIs) and kinase inhibitors has emerged as a promising strategy for liver cancer treatment in recent years. However, the clinical factors predicting the outcomes of combination therapy in patients with advanced liver cancer remain uncertain. Therefore, this study investigated the relationships between clinical predictors and the efficacy of ICI plus kinase inhibitor therapy to personalize treatment plans.

Methods: We retrospectively enrolled 98 patients who received combination treatment with ICIs and kinase inhibitors for advanced HCC. Based on blood lipid levels and other clinical factors prior to treatment, we investigated potential biomarkers that could predict treatment responses in this patient population.

Results: Mean progression-free survival (PFS) and overall survival (OS) in this cohort were 10.1 and 17.2 months, respectively. Via multivariate analysis, the absence of extrahepatic metastasis, the absence of portal vein thrombosis (PVT), neutrophil-to-lymphocyte ratio (NLR) < 3.225, platelet-to-lymphocyte ratio (PLR) < 140.75, and prognostic nutritional index (PNI) ≥ 37.25 were identified as independent predictors of improved PFS. Factors associated with better OS included PLR < 140.75 and total cholesterol (TC) < 3.46 mmol/L. Univariate analysis identified significant associations of Eastern Cooperative Oncology Group performance status (ECOG PS), hepatitis B virus (HBV) DNA levels, Child-Pugh classification, alpha-fetoprotein (AFP), TC, and the receipt of regorafenib with PFS. Additionally, ECOG PS, Child-Pugh classification, AFP, PVT, NLR, PNI, and the receipt of regorafenib were significantly associated with OS.

Conclusions: PLR and TC were potential clinical predictive factors for survival outcomes in patients with advanced HCC who received ICI/kinase inhibitor combination therapy. It is important to know the clinical characteristics of patients prior to treatment initiation to optimize outcomes.

Breast cancer, a prevalent malignancy among women, has various physical and psychological impacts. This comprehensive review offers an in-depth look at multidisciplinary dermo-aesthetic intervention approaches, emphasizing the balance between oncological therapies and the management of these effects. The information presented spans specialties such as aesthetic medicine, plastic surgery, dermatology, physiotherapy, nutrition, odontology, and gynecology. This review, which serves as a clinical guide, aims to establish a safe protocol for non-medical interventions involving oncologists, physicians, and specialists from various areas in patients with breast cancer focused on improving their quality of life. This work offers personalized and integrative care strategies for the eradication of cancer. However, it is still necessary for patients to consult with their oncologist before undergoing any dermo aesthetic treatment.

Lung carcinoids are rare tumors representing 1-2% of all invasive lung malignancies. They include typical and atypical carcinoids, whose distinction is made based on the mitotic index and presence or absence of necrosis. The 10-year overall survival for stage IV typical carcinoid is 47% and 18% for atypical carcinoid, reflecting the indolent growth of these tumors. There are limited approved treatment options for them and most of the evidence comes from retrospective analyses, single-arm trials, subgroup analysis of phase II/III trials for metastatic neuroendocrine tumors and extrapolation of data from phase III trials for gastroenteropancreatic neuroendocrine tumors. Management of metastatic lung carcinoids requires a multidisciplinary standardized approach in specialized centers. Treatment should have a dual objective, control of tumor growth and control of symptoms related to hypersecretion syndromes, aiming to improve quality of life and survival. In the continuum of treatment disease, locoregional treatment options need to be considered in parallel with systemic treatments. In this paper, we review the present treatment options and their rational and we give an insight into future alternatives.

Objective: High-grade gliomas are aggressive brain tumors with poor prognoses. Understanding the factors that influence their progression is crucial for improving treatment outcomes. This study investigates the prognostic significance of panimmune inflammation in patients diagnosed with high-grade gliomas.

Materials-methods: Data from 89 high-grade glioma patients were analysed retrospectively. The Panimmune inflammation Value (PIV) of each patient meeting the eligibility criteria was calculated on the basis of platelet, monocyte, neutrophil, and lymphocyte counts obtained from peripheral blood samples taken on the first day of treatment. PIV is calculated using the following formula: PIV = T × M × N ÷ L. A receiver operating characteristic (ROC) analysis was employed to identify the optimal cut-off value for PIV about progression-free survival (PFS) and overall survival (OS) outcomes. The primary and secondary endpoints were the differences in OS and PFS between the PIV groups. The Kaplan‒Meier method was used for survival analyses.

Results: The ROC analysis indicated that the optimal PIV threshold was 545.5, which exhibited a significant interaction with PFS and OS outcomes. Patients were subsequently divided into two groups based on their PIV levels: a low PIV (L-PIV) group comprising 45 patients and a high PIV (H-PIV) group comprising 44 patients. A comparative analysis of survival rates indicated that patients with elevated PIV had a shorter median PFS of 4.0 months compared to 8.0 months in the low PIV group (P = 0.797), as well as a reduced median OS of 19.0 months versus not available (NA) in the low PIV group (P = 0.215).

Conclusion: Our study results did not reveal a statistically significant association between H-PIV measurements and reduced PFS or OS. However, PIV effectively stratified newly diagnosed high-grade glioma patients into two distinct groups with significantly different PFS and OS outcomes.

Background: In recent years, evidence has accumulated that a second method of conserving the breast from cancer with re-irradiation as part of treatment may be feasible and safe. Many oncologists are skeptical of breast re-irradiation due to concerns about late complications, so access to quantitative data on the prevalence of breast re-irradiation complications is very important. In this meta-analysis, we determine the prevalence of complications in normal tissue after breast re-irradiation.

Materials and methods: A search was done to recognize qualified studies using EMBASE, MEDLINE, PUBMED, Google Scholar, and Cochrane Collaboration Library electronic databases from 2000 to 2023. In total, ten primary studies were applied in this meta-analysis to estimate the prevalence of complications of disorders, skin fibrosis, and chest pain. Heterogeneity was investigated using the I² index and the meta-regression to evaluate variables suspected of causing heterogeneity. Statistical analysis and synthesis were performed using Stata 17.

Results: The average dose received by patients who underwent radiation therapy in two stages was 100.32 Gy, and in these patients, the prevalence of skin fibrosis and disorders was 47% (95% CI 71-22%; I² = 96.76%, P < 0.001) and the prevalence of chest pain was 35% (95% CI 68-8%; I² = 98.13%, P < 0.001).

Conclusions: There is little clinical information about the incidence of complications in breast re-irradiation therapy. This meta-analysis presents the prevalence of complications after breast re-irradiation to help radiation oncologists and physicists make better decisions.

Background: The predictive role of exosomal programmed cell death ligand l (exoPD-L1) in prognosis has been studied extensively; however, there is still no consensus.

Methods: Three databases, including EMBASE, PubMed, and Web of Science, were searched through January 4, 2024. The pooled hazard ratios (HRs) with 95% confidence intervals (95%CIs) were used to identify the relationship between circulating exoPD-L1 and prognosis.

Results: 15 studies with 1091 patients with cancer were included in this statistical analysis. High exoPD-L1 level was correlated with shorter progression-free survival (PFS) (HR = 2.58, 95% CI: 1.75-3.81) and overall survival (OS) (HR = 1.61, 95% CI: 1.32-1.98). Meanwhile, we found that dynamic upregulation of circulating exoPD-L1 in the early stages of immunotherapy was a favorable factor for prognosis (PFS: HR = 0.34, 95% CI: 0.23-0.51; OS: HR = 0.21, 95% CI: 0.13-0.26).

Conclusion: Circulating exoPD-L1 may be a valuable prognostic indicator for patients with cancer and monitoring its changes in the early stages of immunotherapy might be used to predict tumor response and clinical outcome. This conclusion may not apply to superficial tumors.

Purpose: The research aimed to evaluate the connection between pre-treatment inflammatory biomarkers and clinical results in advanced esophageal squamous cell carcinoma (ESCC) receiving immune checkpoint inhibitors.

Materials and methods: Between 2019 and 2022, we analyzed 354 individuals diagnosed with metastatic ESCC who underwent immunotherapy. The study sought to evaluate the impact of specific inflammatory biomarkers (Neutrophil/Lymphocyte Ratio (NLR), C-reactive protein to albumin ratio (CRP/ALB) and Glasgow Prognostic Score (GPS), Cyclooxygenase-2 (COX-2) inhibitors or steroids usage on the effectiveness and survival outcomes of immunotherapy in advanced ESCC. The research utilized Kaplan‒Meier and Cox regression models alongside propensity score matching for analysis.

Results: The findings revealed that elevated pre-treatment NLR (11.0 vs. 14.6 months, p = 0.021) and CRP/ALB (11.4 vs. 14.6 months, p = 0.022) levels were significantly associated with poorer overall survival (OS) outcomes, while the use of steroids did not show a significant difference in OS (15.5 vs. 15.4 months, p = 0.685) between groups. Similarly, no notable disparity in OS was observed between patients treated withCOX-2 inhibitors and those who were not (13.8 vs. 11.0 months, p = 0.054).

Conclusion: Lower levels of NLR and CRP/ALB prior to treatment were linked to better effectiveness and OS in immunotherapy for advanced ESCC. The study did not identify a significant relationship between OS in patients with esophageal cancer and the use of either steroids or COX-2 inhibitors.
