Background: Lung cancer remains the leading cause of cancer-related mortality worldwide. Advances in screening, diagnosis, and management have transformed clinical practice, particularly with the integration of immunotherapy and target therapies. Methods: A systematic literature search was carried out for the period between October 2016 to September 2024. Phase II and III randomized trials evaluating ICI monotherapy, ICI–chemotherapy combinations, and dual ICI regimens in patients with advanced NSCLC were included. Outcomes of interest included overall survival (OS), progression-free survival (PFS), and treatment-related adverse events (AEs). Results: PD-1-targeted therapies demonstrated superior OS compared to PD-L1-based regimens, with cemiplimab monotherapyranking highest for OS benefit (posterior probability: 90%), followed by sintilimab plus platinum-based chemotherapy (PBC) and pemetrexed—PBC. PFS atezolizumab plus bevacizumab and PBC, and camrelizumab plus PBC were the most effective regimens. ICI–chemotherapy combinations achieved higher ORRs but were associated with greater toxicity. The most favorable safety profiles were observed with cemiplimab, nivolumab, and avelumab monotherapy, while atezolizumab plus PBC and sugemalimab plus PBC carried the highest toxicity burdens. Conclusions: In PD-L1-unselected advanced NSCLC, PD-1 blockade—particularly cemiplimab monotherapy—and rationally designed ICI–chemotherapy combinations represent the most efficacious treatment strategies. Balancing efficacy with safety remains critical, especially in the absence of predictive biomarkers. These findings support a patient-tailored approach to immunotherapy and highlight the need for further biomarker-driven and real-world investigations to optimize treatment selection. Full article

Background: There has been a reduction in successful H. pylori eradication rates recently, which is largely attributed to increasing antibiotic resistance. In areas of high dual clarithromycin and metronidazole resistance such as ours, Maastricht VI/Florence guidelines recommend bismuth quadruple therapy (BQT) as first line of therapy; however, the availability of bismuth was poor in Ireland until recently. Similarly, tetracycline, a component of BQT, is restricted locally, with doxycycline (D) being approved and reimbursed for most indications. Aims: To assess the efficacy of BQT-D therapy for H. pylori eradication in an Irish cohort. Methods: All patients testing positive for H. pylori in three Irish referral centres by urea breath test, stool antigen, or histology were treated prospectively with BQT-D (bismuth subcitrate 120 mg QDS, metronidazole 400 mg TDS, doxycycline 100 mg BD and esomeprazole 40 mg BD) for 14 days. Eradication was evaluated with a urea breath test (UBT) >4 weeks after therapy cessation or by stool antigen testing, as available. Outcomes were recorded and analysed according to demographics and H. pylori treatment history of the patients. Results: 217 patients completed post-eradication testing. Of which, 124 (57%) were female, with a mean age 52 years. 180 patients (83%) were treatment-naïve. A total of 165/180 (92%) of the treatment-naïve patients had successful eradication. There was no association between eradication and gender or age in this cohort (p = 0.3091, p = 0.962 respectively). A total of 29 patients received this therapy as second-line therapy, of which 22 (76%) had successful eradication. Eight patients received the regimen as rescue therapy, with seven (88%) having successful eradication. No serious adverse events were reported. Eleven individuals (6.5%) commented on the complicated nature of the regimen, with 11 tablets being taken at five intervals daily. Conclusions: BQT-D as first-line therapy for H. pylori infection is highly effective in a high dual-resistance population, achieving >90% eradication. BQT-D as a second-line treatment performed less well. Our data support BQT-D as a first-line treatment. Full article

Background/Objectives: Upper tract urothelial carcinoma (UTUC) is a rare and biologically distinct subset of urothelial malignancies, comprising approximately 5–10% of urothelial cancers. UTUC presents unique diagnostic and therapeutic challenges, with both a higher likelihood of invasive disease at presentation and a less favorable prognosis compared to urothelial carcinoma of the bladder. Current treatment strategies for UTUC are largely derived from bladder cancer studies, underscoring the need for UTUC-directed research. This review provides a comprehensive overview of UTUC, encompassing diagnostic approaches, systemic and intraluminal therapies, surgical management, and future directions. Methods: A narrative review was conducted synthesizing evidence from guideline-based recommendations, retrospective and prospective clinical studies, and ongoing trials focused on UTUC. Results: Neoadjuvant cisplatin-based chemotherapy is increasingly preferred in UTUC due to the risk of postoperative renal impairment that may preclude adjuvant cisplatin use. Surgical management includes kidney-sparing approaches and radical nephroureterectomy (RNU), with selection guided by tumor risk and patient comorbidities. While endoscopic management (EM) preserves renal function, it carries a higher recurrence and surveillance burden; RNU remains standard for high-risk cases. Systemic therapy for advanced and metastatic UTUC mirrors that of bladder urothelial carcinoma. Enfortumab vedotin (EV) plus pembrolizumab showed superior efficacy over chemotherapy in the EV-302 trial, with improved response rate, progression-free survival, and overall survival across subgroups, including UTUC. For patients ineligible for EV, the CheckMate-901 study supported first-line chemoimmunotherapy with gemcitabine, cisplatin, and nivolumab. Further systemic therapy strategies include maintenance avelumab post-chemotherapy (JAVELIN Bladder 100), targeted therapies such as erdafitinib (THOR trial), and trastuzumab deruxtecan (DESTINY-PanTumor02) in FGFR2/3-altered and HER2-positive disease, respectively. Conclusions: Historically, the therapeutic landscape of UTUC has been extrapolated from bladder cancer; however, ongoing research specific to UTUC is deriving more precise regimens involving the use of immune checkpoint inhibitors, antibody–drug conjugates, and biomarker-driven therapies.

Background: Despite recent advances in the management of metastatic renal cell carcinoma (mRCC), real-world outcomes remain heterogeneous, and early treatment failure is common. Predictive biomarkers for time to treatment failure (TTF) outside clinical trials are poorly characterized. Objective: To identify clinical and laboratory predictors associated with early treatment failure in a real-world cohort of mRCC patients treated with immune checkpoint inhibitors (ICIs), tyrosine kinase inhibitors (TKIs), or combination regimens. Methods: We conducted a retrospective, single-center analysis of patients with metastatic non-urothelial RCC treated between 2018 and 2023. Cox proportional hazards regression was used to evaluate the association between baseline biological parameters and TTF for each treatment regimen. Results: Among 137 patients receiving first-line therapy, 50 received Ipilimumab + Nivolumab, 49 Sunitinib, and 17 Avelumab + Axitinib. For Ipilimumab + Nivolumab, elevated AST was significantly associated with shorter TTF. For Avelumab + Axitinib, shorter TTF was associated with lymph node metastases, low lymphocyte count, low creatinine, low BMI, and low hemoglobin. For Cabozantinib in subsequent lines, a higher platelet count, ALT, and presence of liver metastases were associated with shorter TTF. No statistically significant predictors were found for Nivolumab used in the second-line setting. Conclusions: Routine, accessible biomarkers such as AST, hemoglobin, lymphocyte count, and creatinine may serve as predictors of treatment failure in specific therapeutic contexts. These findings support risk-adapted strategies and individualized monitoring in real-world clinical practice, though further validation in larger cohorts is warranted. Full article

Background and Objectives: Epithelial ovarian cancer (EOC) remains the deadliest gynecologic malignancy, yet the psychosocial dynamics of early survivorship are inadequately described. We prospectively quantified six-month trajectories in the quality of life in a consecutive cohort of 88 women newly diagnosed with EOC and explored clinical moderators of change. Methods: Eighty-eight consecutive patients (mean age 59.1 ± 10.7 years) completed the SF-36, WHOQOL-BREF, EORTC QLQ-C30, and 10-item Perceived Stress Scale (PSS-10) at baseline (pre-therapy) and six months after cytoreductive surgery ± platinum-based chemotherapy. Stage (FIGO I–II vs. III–IV) and treatment pathway (primary debulking surgery, neoadjuvant chemotherapy plus interval debulking, chemotherapy only) data were recorded. Results: Global QoL improved significantly (EORTC Global Health +5.9 ± 7.7 points; p < 0.001) while perceived stress declined (ΔPSS −3.6 ± 5.1; p < 0.001). SF-36 Physical Functioning rose 4.7 ± 7.9 points (p < 0.001) and Mental Health 4.4 ± 7.9 points (p = 0.004). The WHOQOL Physical and Psychological domains gained 4.7 ± 7.1 and 4.3 ± 7.4 points, respectively (both p < 0.01). Advanced-stage patients experienced larger stress reductions than early-stage patients (−4.1 ± 2.7 vs. −2.9 ± 2.2; p = 0.028) but comparable QoL gains. Greater stress relief correlated with greater mental-health improvement (r = −0.51) and global-health gains (r = −0.45) (all p < 0.001). Treatment pathway did not significantly influence trajectories. Conclusions: Early survivorship after first-line ovarian-cancer therapy was characterized by the clinically meaningful recovery of physical and emotional functioning together with the moderate alleviation of perceived stress. Improvements were observed irrespective of stage and treatment strategy, suggesting that contemporary multimodal regimens do not inevitably compromise patient-reported outcomes. Our estimates provide preliminary effect sizes that should be validated in multi-center cohorts with longer follow-up. Full article

Background: In September 2021, pemigatinib received Health Canada approval for previously treated locally advanced/metastatic cholangiocarcinoma (CCA) with FGFR2 rearrangements/fusions. This retrospective study aimed to characterize the real-world management and outcomes of patients with CCA receiving pemigatinib through a Canadian patient support program (PSP). Methods: We evaluated a multi-centre case series of Canadian patients who were prescribed pemigatinib between September 2021 and January 2023 for eligible CCA diagnoses and enrolled in the PSP. The retrospective study data included demographic and disease-, treatment-, and outcome-related information, and these were collected using a survey of prescribing physicians. Results: Of the 26 patients who initiated pemigatinib in the PSP, we received survey responses for 18 (69%). Their median age was 57 years, 67% were female, 61% had stage IV disease, and 83% had intrahepatic CCA. Prior to pemigatinib, a partial hepatectomy was performed in 44% of the patients, and 66% of the patients received 2–4 prior lines of systemic therapy. All patients were treated with platinum-based regimens as the first-line treatment for unresectable/metastatic disease. The median follow-up time on pemigatinib was 12.6 (range: 2.3–28.4) months, and their median real-world progression-free survival (rwPFS) was 12.1 months (95% CI 7.2-NR). The physician-assessed objective response and disease control rates were 56% and 89%, respectively. For the nine patients who discontinued pemigatinib, the median treatment duration was 10.6 months (range: 0.8–21.7). Disease progression was the most common reason for discontinuation (89%). None discontinued due to adverse events. Conclusions: Objective response rates, disease control rates, and a PFS comparable to that in the phase 2 FIGHT-202 trial was reported with pemigatinib use in this Canadian PSP cohort. Full article

Background: Multidrug-resistant tuberculosis (MDR-TB) remains a significant public health threat in Central Asia, where rising resistance to first-line anti-TB drugs challenges control efforts. As of 2024, the World Health Organization (WHO) reports that over 2.5% of new TB cases and 18% of previously treated cases are resistant to first-line TB drugs worldwide. Objectives: This integrative review synthesizes current evidence on MDR-TB in Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, with a focus on infection control, diagnostic advancements, and evolving treatment strategies. Methods: A comprehensive literature search was conducted across five electronic databases: PubMed, Scopus, Web of Science, Embase, World Health Organization (WHO) Global Tuberculosis Database, and ClinicalTrials.gov. A total of 29 articles from Central Asian countries met the inclusion criteria. Results: Four main themes were identified: “genetic variability and resistance patterns of MDR-TB strains”; “barriers to effective treatment”; “diagnostic tools”, and “infection control strategies”. Conclusions: This review underscores the importance of comprehensive, multifactorial approaches in addressing drug-resistant TB in the region. The implementation of early diagnosis and all-oral treatment regimens has improved adherence in recent studies. Full article

This retrospective cohort study evaluated characteristics, treatment patterns, and clinical outcomes in adults with locally advanced/metastatic urothelial carcinoma (la/mUC) receiving first-line (1L) systemic treatment with or without avelumab 1L maintenance (1LM) between January 2020 and July 2023. The index date was the first date with a claim for 1L systemic therapy after a la/mUC diagnosis. Patients with continuous health plan enrollment for ≥6 months before and ≥1 month after the index date were identified from Carelon Research’s Healthcare Integrated Research Database. Of 2820 patients receiving 1L treatment, 37.0% received platinum-based chemotherapy (PBC); 39.0%, immuno-oncology (IO) monotherapy; and 24.0%, other therapies. Renal disease and other comorbidities influenced 1L regimen choice. Healthcare resource utilization (HCRU) and costs were reported for patients receiving second-line (2L) treatment. HCRU was high in 32.8% of patients (926 of 2820) who received 2L treatment. Median all-cause direct medical costs per patient per month were USD 15,859, USD 19,781, USD 11,346, and USD 9516 for 1L PBC, 1L PBC + avelumab 1LM, 1L IO monotherapy, and 1L other therapies, respectively. Most direct healthcare costs were attributed to all-cause outpatient visits. Full article

Background: Chronic lymphocytic leukemia (CLL) is a prevalent hematologic malignancy that predominantly affects elderly individuals, posing significant clinical challenges due to patient comorbidities and inherent resistance to conventional chemotherapy. The emergence of targeted therapies combining venetoclax, a selective inhibitor of the anti-apoptotic protein BCL-2, with anti-CD20 monoclonal antibodies has dramatically transformed the treatment landscape. Methods: This retrospective observational study analyzed the differential impacts of first-line venetoclax-obinutuzumab (VenO) and second-line venetoclax-rituximab (VenR) on immunoglobulin G (IgG) levels and absolute neutrophil count (ANC) in CLL patients. Results: Our findings indicate that during first-line VenO therapy, a significant improvement in ANC levels from baseline was observed, whereas patients undergoing second-line VenR therapy demonstrated limited impact on ANC and the decreasing tendency in IgG levels. Patients treated with VenR had a longer disease history and previous exposure to other treatment regimens, primarily chemoimmunotherapy, which could negatively influence immune recovery, making direct comparisons between these two treatment lines challenging. Although this observational study did not directly compare infection rates, the observed enhancement of ANC levels in patients receiving VenO suggests a potential for lower infection risk compared to pretreated VenR patients. Conclusions: These results underscore the clinical significance of considering both the treatment line and the patient’s prior therapeutic history when selecting venetoclax-based regimens for CLL. The potential association of first-line VenO with improved immunological parameters and the complex impact of prior therapies on immunological recovery with second-line VenR warrant further prospective investigation into the correlation between treatment regimen, patient history, immune function, and infectious complications.

Pancreatic cancer is the third leading cause of cancer-related death in the US. First-line chemotherapy regimens for pancreatic ductal adenocarcinoma (PDAC) include FOLFIRINOX or gemcitabine (Gem) with or without paclitaxel (Ptx); however, 5-year survival with these regimens remains poor. Previous work has demonstrated protein arginine methyltransferase 5 (PRMT5) to be a promising therapeutic target in combination with Gem for the treatment of PDAC; however, these findings have yet to be confirmed in relevant preclinical models of PDAC. To test the possibility of PRMT5 as a viable therapeutic target, clinically relevant orthotopic and metastatic patient-derived xenograft (PDX) mouse models of PDAC growth were utilized to evaluate the effect of PRMT5 knockout (KO) or pharmacologic inhibition on treatment with Gem alone or Gem with Ptx. Primary endpoints included tumor volume, tumor weight, or metastatic tumor burden as appropriate. The results showed that Gem-treated PRMT5 KO tumors exhibited decreased growth and were smaller in size compared to Gem-treated wild-type (WT) tumors. Similarly, the Gem-treated PRMT5 KO metastatic burden was lower than the Gem-treated WT metastatic burden. The addition of a PRMT5 pharmacologic inhibitor to Gem and Ptx therapy resulted in a lower final tumor weight and fewer metastatic tumors. The depletion of PRMT5 results in increased DNA damage in response to Gem and Ptx treatment. Thus, PRMT5 genetic depletion or inhibition in combination with Gem-based therapy improved the response in primary and metastatic PDAC in clinically relevant mouse models, suggesting that PRMT5 is a viable therapeutic target for combination therapy in PDAC.

Background/Objectives: Despite advances in immunotherapy, reliable biomarkers beyond PD-L1 expression are urgently needed to optimize treatment decisions in advanced non-squamous NSCLC. Thyroid Transcription Factor-1 (TTF-1), a biomarker associated with favorable prognosis in chemotherapy-treated patients, has unclear prognostic implications in the immunotherapy era. Methods: We conducted a multicenter retrospective study involving 163 advanced non-squamous NSCLC patients treated with first-line immunotherapy or chemo-immunotherapy and an additional historical chemotherapy-only cohort (n = 37). We evaluated the prognostic significance of TTF-1 expression for progression-free survival (PFS) and overall survival (OS). A systematic review and meta-analysis, performed following PRISMA guidelines, integrated our findings with existing evidence. Hazard ratios (HRs) were calculated using Cox proportional hazards models. Results: TTF-1 negativity was associated with significantly worse median PFS (6.7 vs. 16 months; HR 2.22, 95% CI 1.59–3.13; p < 0.001) and OS (11.5 vs. 26.4 months; HR 2.33, 95% CI 1.64–3.45; p < 0.001) compared to TTF-1 positivity. The prognostic value of TTF-1 was independent of PD-L1 status, with limited predictive relevance of PD-L1 expression observed within TTF-1-negative tumors. Meta-analysis (9 studies, 14 cohorts, n = 2019 patients) confirmed significantly inferior outcomes for TTF-1-negative patients across multiple immunotherapy-based regimens (pooled HR for PFS: 1.75, 95% CI 1.50–2.04; OS: 1.76, 95% CI 1.45–2.14). Conclusions: TTF-1 negativity independently predicts poor prognosis in advanced non-squamous NSCLC treated with immunotherapy-based regimens, identifying patients with limited benefit despite high PD-L1 expression. Integrating TTF-1 status into clinical practice may guide personalized treatment strategies, highlighting the need for prospective validation. Full article

Hepatocellular carcinoma (HCC), the most common primary liver cancer, remains a leading cause of cancer-related mortality worldwide. Its often-silent progression results in late-stage diagnosis, limiting curative options and necessitating systemic therapy for many patients. The presence of underlying cirrhosis in most cases further complicates treatment decisions. While the approval of sorafenib in 2007 marked a major milestone in systemic therapy for HCC, the treatment landscape has since evolved significantly, particularly with the advent of immune checkpoint inhibitors and anti-angiogenic agents. Combination regimens, such as atezolizumab plus bevacizumab, have demonstrated superior outcomes and are now considered standard first-line options. Despite these advances, efforts to translate insights from HCC’s molecular pathogenesis into personalized treatments have been limited. This narrative review explores the current systemic therapy options for HCC, from first-line to subsequent-line treatments, and highlights emerging strategies, including novel immunotherapies and targeted agents. We emphasize the need for individualized treatment approaches that consider tumor biology, liver function, and performance status, and we outline future directions for research aimed at improving outcomes in this complex and evolving field.

Background and Objectives: Despite developments in cervical cancer (CC) treatment, an advanced stage is a poor prognostic factor. Cervical cancer is an immunogenic tumor in which viruses, like HPV, play a role in carcinogenesis. Therefore, systemic inflammatory markers (SIMs) may have prognostic value. Most studies on SIMs focus on the early stage by evaluating pretreatment levels. This study aims to evaluate the prognostic and predictive values of both pretreatment and post-treatment parameters at the advanced stage, as well as treatment efficacy after progression with first-line treatment. Materials and Methods: A total of 133 advanced-stage CC patients with progression on first-line platin–paclitaxel and bevacizumab were evaluated retrospectively. Demographic and histopathological characteristics were recorded along with treatment details. Pre-treatment baseline blood parameters and post-treatment follow-up values were recorded to calculate SIMs as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammatory response index (SIRI). Results: Median values for SIMs were accepted as cut-off values. Post-treatment values demonstrated stronger predictive power, with pre-treatment SIRI and NLR being significant only in univariate analysis, but not in multivariate analysis. High post-treatment SIRI (>2.1) was correlated with shorter overall survival (OS) and considered a poor prognostic factor. High post-treatment SIRI (>2.1), -SII (>746), and -PLR (>197) emerged as independent prognostic factors for progression-free survival (PFS). Their prognostic values were clearer in the whole population and the metachronous metastatic subgroup. Rechallenge of platinum-based chemotherapy was an option for those who had at least 6 months of PFS with first-line platinum-based chemotherapy. Bevacizumab addition to single-agent or combination regimens led to improved ORR as well. Conclusions: Post-treatment SIRI is a promising prognostic factor for OS, while post-treatment SIRI, SII, and PLR may serve as convenient SIMs for PFS. Platinum-based combination chemotherapy reinduction is a feasible second-line treatment strategy, especially with the addition of bevacizumab. Full article

Background/Objectives: Intradetrusor botulinum toxin injection is a well-established third-line therapy for patients with refractory overactive bladder (OAB) and detrusor overactivity (DO). Botulinum toxin type A (BoNT-A) is most commonly used due to its prolonged therapeutic duration. We aimed to evaluate the effectiveness of intradetrusor BoNT-A injection therapy in managing refractory OAB by performing a urodynamic study (UDS). Methods: The patients were prospectively enrolled between February 2020 and March 2021. The patients received treatment regimens comprising behavioral modification therapy, pelvic floor muscle physiotherapy, and/or OAB medications for at least three months. The UDS procedure was carried out by a single examiner, in accordance with the International Continence Society standards for good urodynamic practice. A total of 100 units of BoNT-A was dissolved in 10 mL of saline, and 0.5 mL (5 units) was injected at 20 sites on the posterior wall of the bladder. The primary endpoint was the change in DO, which was measured using the UDS from the baseline to two months after treatment with BoNT-A. Results: Prior to treatment initiation, DO was observed in all the patients during the UDS. The occurrence of DO during the filling phase demonstrated a significant decrease following treatment, with DO no longer identified in 27.3% of the patients. The first sensation of bladder filling, maximum cystometric capacity, DO, and terminal DO all demonstrated significant improvement after intradetrusor BoNT-A injection, based on the UDS. The OAB symptom scores also significantly decreased after BoNT-A therapy. Conclusions: The present study demonstrated that intradetrusor BoNT-A injection significantly improved symptoms in patients with OAB who had been unresponsive to various treatments. This study also demonstrated the usefulness of performing a UDS before and after treatment to prove the efficacy of BoNT-A. Full article

Background: Recently, the addition of anti-CD38 monoclonal antibodies (mAbs) to standard first-line triplet regimens, including a proteasome inhibitor (PI), an immunomodulatory drug (IMiD) and dexamethasone, has led to the introduction of quadruplets in clinical practice. Methods: A systematic search was conducted (end-of-search: 9 November, 2024) for clinical trials investigating first-line anti-CD38 mAb-based quadruplets in combination with a PI and an IMiD. Pooled proportions and effect-estimates along with 95% confidence intervals were calculated with common-effect and random-effects models and further subgroup and meta-regression analyses were performed. Results: The pooled 2-, 3- and 4-year progression-free survival (PFS) rates were 89%, 77% and 86%, respectively. Furthermore, patients treated with quadruplets demonstrated a 46% reduced risk for disease progression or death (HR = 0.54, 95% CI: 0.46–0.64) compared to those on triplets. Overall survival (OS) rates were consistently high, ranging from 83% to 96% between different regimens. High rates of deep responses that deepened over time were observed, with the pooled proportion of patients achieving at least complete response being 64%. Importantly, the pooled MRD negativity rate was 62%, whereas patients treated with quadruplet first-line therapy had 2.5 times the odds to be MRD negative at any point compared with those on triplets. Moreover, the odds for sustained 12-month MRD negativity were thrice as much with quadruplets compared to triplets. Finally, while no increase in serious adverse events was observed with quadruplet regimens compared to triplets, a 46% statistically significant increased risk for grade 3–4 neutropenia and thrombocytopenia was observed, along with a 14% increased risk for grade 3–4 infections. Conclusions: The addition of anti-CD38 mAbs to standard triplet regimens has shown particularly favorable outcomes, supporting their integration in the upfront treatment of patients with NDMM. However, close monitoring for hematological toxicity and infections is essential. Full article
