Surgical resection remains the cornerstone of curative-intent treatment for both oncogene and non-oncogene addicted early-stage non-small cell lung cancer, with neoadjuvant/adjuvant chemotherapy providing only a modest benefit in terms of disease-free survival and overall survival. Currently, in non-small-cell lung cancer without actionable molecular alterations, the addition of neoadjuvant or perioperative immunotherapy to chemotherapy has become the standard of care for resectable disease, with significant improvements in the rates of complete pathological response, major pathological response, and event-free survival. In terms of oncogene-addicted non-small-cell lung cancer, adjuvant treatment of completely resected disease with the third-generation EGFR inhibitor osimertinib in patients harboring activating EGFR mutations or the second-generation ALK inhibitor alectinib in patients with an ALK fusion/translocation has brought about a paradigm shift by significantly improving event-free survival and, in the case of osimertinib, overall survival. A glimpse into the future management of patients with early-stage disease and a common EGFR mutation or an ALK fusion/translocation may reveal a perioperative use of the respective targeted treatment. Data for the rest of the actionable molecular alterations remain limited, and those tumors are usually treated with algorithms used for non-oncogene-addicted non-small-cell lung cancer. This review aims to summarize all existing evidence about the current management of patients with early-stage non-small-cell lung cancer and actionable molecular alterations and to examine the future directions in this rapidly evolving field.

Background/Objectives: Relapsed and refractory (rr) primary large B-cell lymphoma of the central nervous system (PCNSL) has a dismal prognosis, and the standard of care is not established. The most common genetic imbalance includes the B-cell lymphoma 2 (BCL-2) locus. Methods: We planned a bi-centric phase Ib dose-escalation study with the chemotherapy-free combination of the BCL-2 inhibitor venetoclax and CD20 antibody obinutuzumab for rrPCNSL patients in Germany. The intended treatment consisted of 6 cycles of fixed-dose obinutuzumab at 1000 mg intravenously every 3 weeks, and an oral daily dose of 600, 800, or 1000 mg venetoclax, depending on the planned dosing group, followed by a 12-month venetoclax maintenance period. The primary endpoint was the pharmacokinetics of venetoclax and obinutuzumab in cerebrospinal fluid (CSF). Results: This study was prematurely terminated after registration of 5/15 (33%) patients in dosing group 1 (600 mg oral daily dose of venetoclax) between May 2020 and November 2021. The mean ratio of the concentration of venetoclax in CSF over peripheral blood was 0.55% (±0.28 standard deviation (SD)) and 0.25% (±0.23 SD) for obinutuzumab. Two of five patients achieved complete remission, and each one patient achieved partial remission and stable disease as best response. The median duration of response was 6.5 months (range 0.7–47). Conclusions: Venetoclax and obinutuzumab can penetrate into the central nervous system, but the CSF concentration did not correlate with the outcome. The combination is feasible, tolerable, and may lead to durable responses in selected rrPCNSL patients. Full article

Background: The year 2025 witnessed paradigm-shifting advances in gynecologic oncology, with pivotal clinical trial results redefining therapeutic standards across cervical, ovarian, endometrial, and vulvar cancers. Objectives: This systematic review aimed to comprehensively identify, synthesize, and critically evaluate pivotal phase II and III randomized controlled trials and major studies presented at the major annual meetings, alongside significant peer-reviewed publications from 2025 that introduce innovative therapeutic strategies across gynecologic malignancies. Methods: Conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, this review involved exhaustive searches of electronic databases (PubMed/MEDLINE, Embase), conference proceedings (ASCO 2025, ESMO 2025), and major oncology journals for records from January to December 2025. Inclusion criteria encompassed: (1) Phase II or III randomized controlled trials (RCTs) and (2) Non-randomized studies (including phase I and II trials), reporting on novel therapeutic approaches in gynecologic oncology. All studies were required to report primary survival endpoints (overall survival or progression-free survival) or key efficacy outcomes. Study selection, data extraction, and methodological quality assessment were performed independently by two reviewers, with disagreements resolved through consensus or third-party adjudication. Results: From 1842 records, 23 studies met inclusion criteria (17 phase-III RCTs and 6 non-phase III RCTs/early-phase studies), distributed as follows: cervical cancer (9 studies, 39%), ovarian cancer (9 studies, 39%), endometrial cancer (4 studies, 17.5%), and vulvar cancer (1 study, 4.5%). The major advances identified include: (1) In cervical cancer, the KEYNOTE-A18 trial established pembrolizumab combined with chemoradiotherapy as a new standard for high-risk locally advanced disease, while the PHENIX trial validated sentinel lymph node biopsy as a safe surgical de-escalation strategy. (2) In ovarian cancer, the ENGOT-ov65/KEYNOTE-B96 trial demonstrated the first statistically significant overall survival improvement with an immune checkpoint inhibitor in platinum-resistant recurrent disease, establishing pembrolizumab plus weekly paclitaxel as a new standard of care. Novel therapeutic mechanisms, including glucocorticoid receptor modulation (ROSELLA trial) and cadherin-6-targeted antibody-drug conjugates (REJOICE-Ovarian01), showed remarkable efficacy. (3) In endometrial cancer, updated analyses from NRG GY018 and RUBY trials solidified the role of first-line immuno-chemotherapy, with differential benefits according to mismatch repair status. (4) In vulvar cancer, a pivotal phase II study demonstrated meaningful clinical activity of anti-PD-1 therapy in advanced disease. (5) The extensive circulating tumor DNA analysis from the CALLA trial provided crucial insights into biomarker dynamics in cervical cancer. Conclusions: The convergence of high-impact data from 2025 established multiple new standards of care, emphasizing biomarker-driven approaches, immunotherapy integration across disease stages, and novel mechanisms to overcome resistance, while highlighting challenges in treatment sequencing and global access.

Background/Objectives: Prostate cancer (PC) is one of the most commonly diagnosed malignancies globally; depending on the treatment strategy used, erectile dysfunction (ED) is a frequently reported adverse outcome among PC patients. The current study evaluated ED prevalence among Pakistani PC patients and its effects on physical, psychological, and social well-being, aiming to address critical gaps in survivorship care for this population. Methods: A cross-sectional, multicenter, observational, questionnaire-based study was conducted in Rawalpindi and Islamabad, Pakistan, from February to April 2025. Health-related quality of life (HRQoL) among PC patients was measured using the Short Form Health Survey 36 (SF-36), while ED prevalence and severity were assessed by the International Index of Erectile Function (IIEF) instrument. Results: Among N = 400 PC patients, surgical treatments predominated (radical prostatectomy: 61.0%; n = 244), while hormonal (androgen-deprivation therapy: 31.5%; n = 126) and chemotherapy (23.3%; n = 93) were also commonly utilized. ED experience was high among PC patients in the erectile function (40.8%; n = 163) and in the intercourse satisfaction (45.0%; n = 180) domains; these showed moderately strong and significant positive correlations across all SF-36 domains, particularly physical functioning (r = 0.52; p < 0.001) and social functioning (r = 0.49; p < 0.001). Regression analysis confirmed sexual function domains explained 60% of HRQoL variance (adjusted R² = 0.60). Conclusions: This study reveals high rates of treatment-related ED—and its biopsychosocial impact–among Pakistani PC patients, with significant negative impacts on HRQoL. The findings underscore the urgent need to integrate sexual health management into standard oncological care practices to improve holistic patient outcomes. Full article

We introduce the Onco-Hem Connectome (OHC), a patient similarity network (PSN) designed to organize real-world hemato-oncology inpatients by exploratory phenotypes with potential clinical utility. Background: Polypharmacy and drug–drug interactions (DDIs) are pervasive in hemato-oncology and vary with comorbidity and treatment intensity. Methods: We retrospectively analyzed a 2023 single-center cohort of 298 patients (1158 hospital episodes). Standardized feature vectors combined demographics, comorbidity (Charlson, Elixhauser), comorbidity polypharmacy score (CPS), aggregate DDI severity score (ADSS), diagnoses, and drug exposures. Cosine similarity defined edges (threshold ≥ 0.6) to build an undirected PSN; communities were detected with modularity-based clustering and profiled by drugs, diagnosis codes, and canonical chemotherapy regimens. Results: The OHC comprised 295 nodes and 4179 edges (density 0.096, modularity Q = 0.433), yielding five communities. Communities differed in comorbidity burden (Kruskal–Wallis ${\epsilon }^2$: Charlson 0.428, Elixhauser 0.650, age 0.125, all FDR-adjusted p < 0.001) but not in utilization (LOS, episodes) after FDR (${\epsilon }^2$ ≈ 0.006–0.010). Drug enrichment (e.g., enoxaparin $\Delta$ = +0.13 in Community 2; vinblastine $\Delta$ = +0.09 in Community 3) and principal diagnoses (e.g., C90.0 23%, C91.1 15%, C83.3 15% in Community 1) supported distinct clinical phenotypes. Robustness analyses showed block-equalized features preserved communities (ARI 0.946; NMI 0.941). Community drug signatures and regimen signals aligned with diagnosis patterns, reflecting the integration of resource-use variables in the feature design. Conclusions: The Onco-Hem Connectome yields interpretable, phenotype-level insights that can inform supportive care bundles, DDI-aware prescribing, and stewardship, and it provides a foundation for phenotype-specific risk models (e.g., prolonged stay, infection, high-DDI episodes) in hemato-oncology.

Many children with cancer referred to physical therapy (PT) do not attend the service. We conducted a pilot study, comprising a cross-sectional survey and interviews with parents of children with acute lymphoblastic leukemia. The survey explored parents’ (1) views on PT service delivery for their child, (2) perspectives on barriers and facilitators, (3) preferred timing to introduce PT, and (4) views on virtual services. Questions were designed based on the Theoretical Domains Framework, and responses were mapped onto the Capability, Opportunity, Motivation–Behavior Change Model. Twenty parents participated in the survey. Although all parents would consider their child accessing PT if deficits were present, access depended on a convenient location (70%) and availability of virtual delivery (45%). While half of the parents preferred PT treatment to be introduced during the maintenance phase of chemotherapy, findings also support earlier introduction during the consolidation phase when services are framed as part of standard care. While most parents perceived that it would be manageable to support home-based PT, barriers included a lack of child’s motivation without therapist support. Seven parents participated in semi-structured interviews. They identified time constraints, distance, and costs as common barriers. Most parents responded positively to hybrid PT models and connections with community locations to mitigate these challenges. Full article

Management of resectable esophageal cancer has evolved into a multidisciplinary paradigm centered on multimodality therapy. Historically, induction chemoradiotherapy followed by surgery, as established by the CROSS trial, became the standard of care for locally advanced disease due to improvements in R0 resection rates and overall survival. More recently, the ESOPEC trial reexamined this paradigm in esophageal adenocarcinoma, demonstrating superior survival and improved systemic disease control with perioperative chemotherapy using the FLOT regimen compared with chemoradiotherapy. In parallel, the MATTERHORN trial further advanced perioperative treatment by showing improved event-free survival with the addition of the immune checkpoint inhibitor durvalumab to FLOT chemotherapy. Alongside these systemic therapy advances, surgical management has transitioned toward minimally invasive and robotic-assisted esophagectomy, offering equivalent oncologic outcomes with reduced perioperative morbidity. This review summarizes the evolving evidence from pivotal clinical trials, highlights ongoing studies integrating immunotherapy, and discusses emerging strategies such as adoptive cell transfer which currently is under investigation for metastatic recurrence, but in the future may provide additional treatment options for resectable esophageal cancer.

Cervical cancer remains a significant global health burden, disproportionately affecting women in low- and middle-income countries despite being preventable. Since 2018, rapid advances in molecular profiling, immunotherapy, refinement of minimally invasive surgery, and targeted therapeutics have transformed diagnostic and therapeutic paradigms. This narrative review synthesizes clinical and translational progress across the continuum of care from 2018 to 2025. We summarize the evolving landscape of precision screening—including HPV genotyping, DNA methylation assays, liquid biopsy, and AI-assisted cytology—and discuss their implications for global elimination goals. Surgical management has shifted toward evidence-based de-escalation with data from SHAPE, ConCerv, and ongoing RACC informing fertility preservation and minimally invasive approaches. For locally advanced disease, KEYNOTE-A18 establishes pembrolizumab plus chemoradiation as a new curative standard, while INTERLACE underscores the benefit of induction chemotherapy. In the metastatic setting, survival outcomes have improved with the integration of checkpoint inhibitors (KEYNOTE-826, BEATcc, EMPOWER-Cervical 1), vascular-targeted therapies, and antibody–drug conjugates, including tisotumab vedotin and emerging HER2 and TROP-2–directed agents. We further highlight emerging biomarkers—PD-L1, TMB, MSI status, HPV integration patterns, APOBEC signatures, methylation classifiers, ctHPV-DNA—and their evolving role in treatment selection and surveillance. Future directions include neoadjuvant checkpoint inhibition, PARP-IO combinations, HER3-directed ADCs, DDR-targeted radiosensitizers, HPV-specific cellular therapies, and AI-integrated precision medicine. Collectively, these advances are reshaping cervical cancer care toward biologically individualized, globally implementable strategies capable of accelerating WHO elimination targets. Full article

Survival rates for children treated for malignant diseases continue to improve, yet many survivors face persistent late oral complications that affect function, aesthetics, and quality of life. Oncological therapy, especially at a young age and following head and neck radiotherapy or intensive chemotherapy, can disrupt dental and craniofacial development, resulting in dental developmental disorders, enamel defects, salivary gland dysfunction, caries susceptibility, periodontal problems, trismus, and osteoradionecrosis of the jaw. Although these effects are partially known, they are frequently underrecognized in routine practice, and many children do not receive adequate long-term dental follow-up. A key challenge highlighted in the recent literature is the absence of structured, evidence-based guidelines for monitoring and managing late oral effects. The article emphasizes the need for clearer recommendations, better communication of oncological treatment histories, and stronger integration of dental professionals within survivorship care. Developing standardized follow-up protocols will be essential to ensure timely detection, consistent management, and improved oral health outcomes for childhood cancer survivors. This article is intended as a narrative review, synthesizing available evidence from key publications to highlight clinically relevant late oral complications and gaps in current survivorship care.

Background/objectives: Improvements in esophageal adenocarcinoma (EAC) treatment have reduced mortality. While chemoradiation before surgery was previously a standard of care, updated guidelines recommend peri-operative chemotherapy without chemoradiation. Continued investigation into optimal non-operative treatment paradigms for patients who defer surgery or are not candidates for surgery and certain chemotherapy regimens is needed. The impact of induction chemotherapy prior to chemoradiation on survival and surgical outcomes remains unclear. This study assessed survival and surgical outcomes in a real-world cohort of EAC patients receiving induction chemotherapy before chemoradiation. Methods: This single-institution, IRB-approved, retrospective cohort study included patients with newly diagnosed stage II-IVb (oligometastatic for IVb) EAC who received definitive chemoradiation (radiation ≥ 40 Gy and two cycles of chemotherapy) +/− esophagectomy from 2007 to 2022. Patients receiving induction chemotherapy were compared to those who did not. Endpoints included survival and surgical outcomes. Results: A total of 141 EAC patients received definitive chemoradiation; 83 received induction chemotherapy before chemoradiation. Patients receiving induction chemotherapy were younger (p < 0.01) with slightly lower performance status (p = 0.27) and presented at a more advanced stage (p < 0.001). Median OS was 3.5 years in the induction chemotherapy group compared to 2.2 years (p = 0.10). There was no difference in pathologic complete response (p = 0.81), esophagectomy frequency (p = 0.87), or surgical downstaging between treatment groups (p = 0.84). Conclusions: In this real-world, single-institutional patient cohort investigating induction chemotherapy prior to chemoradiation in EAC, patients receiving induction chemotherapy did well but did not have a statistically significant improvement in survival outcomes or surgical outcomes. This study showed that significant numbers of real-world patients may not receive esophagectomy. Thus, prospective, randomized clinical trials are warranted to better delineate the efficacy and selection of patients for induction chemotherapy when non-operative approaches are favored.

Triple-Negative Breast Cancer (TNBC) remains the most aggressive breast cancer subtype, characterized by profound heterogeneity and a lack of effective targeted therapies. Although cytotoxic chemotherapy is the standard of care, the rapid emergence of resistance driven by cancer stem cells (CSCs), metabolic plasticity, and the tumor microenvironment limits long-term survival. This review highlights the paradigm shift in TNBC treatment from 2021 to 2025, moving beyond broad cytotoxicity to precision medicine. We first examine the limitations of earlier targeted therapies, such as PI3K/AKT/mTOR inhibitors, which failed due to compensatory feedback loops and toxicity. We then discuss emerging synthetic lethality strategies targeting the G2/M checkpoint (WEE1, ATR) and mitotic kinases (PLK1, TTK) to exploit genomic instability in TP53-mutant tumors. Furthermore, we explore how novel modalities like PROTACs and Antibody–Drug Conjugates (ADCs) are unlocking the “undrugged kinome,” including targets like TNIK, PTK7, and PAK4, which were previously inaccessible. Finally, we propose that future success lies in combinatorial strategies integrating these next-generation kinase inhibitors with ADCs and immunotherapies to dismantle therapeutic resistance.

Background: Rehabilitation of head and neck cancer patients with acquired intraoral defects is challenging and requires multidisciplinary collaboration. This case report describes an integrated surgical and prosthetic approach in which palatal obturator rehabilitation is used to restore palatal integrity, speech, swallowing, aesthetics, and overall quality of life after maxillectomy. The objective is to show how careful surgical planning to optimize prosthetic prognosis, combined with a precisely designed obturator prosthesis, can achieve satisfactory functional rehabilitation. Methods: A man in his 50s with sinonasal carcinoma underwent partial left maxillectomy followed by radiotherapy and chemotherapy. The defect was classified as Aramany class I and Brown class 2b, and the surgical resection was planned to preserve structures favorable to prosthetic support. Prosthetic management included fabrication of a removable partial denture incorporating a hollow-bulb obturator. Results: During trial and delivery, the patient demonstrated improved speech and swallowing, enhanced denture stability, and favorable aesthetics. The patient reported satisfaction with functional and cosmetic outcomes and was provided with instructions for use and cleaning, with a plan for regular follow-up. Conclusions: Palatal obturator prostheses remain a gold standard for unilateral maxillectomy rehabilitation when adequate retention is achievable. Surgical-prosthetic collaboration permits restoring palatal contours, and dentition can normalize speech and swallowing, and substantially improve the quality of life. Full article

Approximately 80% of invasive breast cancers are classified as human epidermal growth factor receptor 2 (HER2)-negative; however, many of these tumors have detectable levels of HER2 surface expression. Trastuzumab deruxtecan (T-DXd) is a HER2-directed antibody-drug conjugate with a membrane-permeable payload that is cytotoxic to both HER2-expressing tumor cells and neighboring cells via the bystander antitumor effect. T-DXd has shown significant antitumor activity in clinical trials for patients with HER2-positive (immunohistochemistry [IHC] 3+ or IHC 2+/in situ hybridization [ISH]+) breast cancer. In addition, the results of the DESTINY-Breast04 trial demonstrated the clinical benefit of T-DXd in patients with HER2-low (IHC 1+ or IHC 2+/ISH−) breast cancer after receiving prior chemotherapy. DESTINY-Breast06 demonstrated the clinical benefit of T-DXd in patients with hormone receptor (HR)-positive, HER2-low (IHC 1+ or IHC 2+/ISH−), and HER2-ultralow (IHC 0 with membrane staining) metastatic breast cancer who had not received prior chemotherapy in the advanced setting. These results validate the need for a standard-of-care diagnostic test to identify HER2-low and HER2-ultralow expression levels in patients with metastatic breast cancer to guide therapeutic decision-making. Furthermore, effective treatment sequencing strategies and adverse event management are essential for maximizing patient benefit. This review presents the identification of HER2-low and HER2-ultralow breast cancer, sequencing of T-DXd with other treatments, and management of common or clinically significant adverse events reported with T-DXd.

The limited efficacy of cytotoxic chemotherapy in the context of gastric cancer treatment is largely driven by profound molecular and biological heterogeneity. In contrast, the development of antibody-mediated therapies has ushered in a new era of precision oncology by enabling selective molecular targeting and immune modulation. This review includes a comprehensive overview of the evolution of antibody-based therapeutics in gastric cancer, highlighting early breakthroughs, subsequent setbacks, and recent advances that have reshaped the treatment landscape. We summarize the current standard regimens targeting HER2, VEGFR2, PD-1/PD-L1, and CLDN18.2 and examine pivotal clinical trials evaluating monoclonal antibodies directed against these pathways. We also discuss emerging therapeutic modalities, including next-generation antibody–drug conjugates (ADCs), bispecific antibodies, and chimeric antigen receptor (CAR) T-cell therapies. Trastuzumab first established HER2-targeted therapy in gastric cancer, but the failure of trastuzumab emtansine (T-DM1) led to a decade-long stagnation until the advent of trastuzumab deruxtecan (T-DXd), which demonstrated robust clinical activity and defined a new standard of care. While bevacizumab failed to improve survival, the anti-VEGFR2 antibody ramucirumab emerged as an effective second-line therapy. Immune checkpoint inhibitors, including nivolumab and pembrolizumab, have been incorporated into first-line treatment for PD-L1-positive disease based on landmark trials such as CheckMate 649 and KEYNOTE-811. More recently, the CLDN18.2-targeted antibody zolbetuximab has expanded therapeutic options for biomarker-selected patients. Concurrently, a diverse pipeline of immune-based strategies—such as TROP2-directed ADCs, bispecific antibodies, and CAR-T cell therapies—is undergoing active clinical development. Together, advances in biomarker-driven antibody therapeutics are accelerating personalized cancer care and improving clinical outcomes in patients with gastric cancer. Full article

High-grade gliomas—particularly glioblastoma (GBM)—remain refractory to standard-of-care surgery followed by chemoradiation, with a median overall survival of ~15 months. Oncolytic viruses (OVs), which selectively infect and lyse tumor cells while engaging antitumor immunity, offer a mechanistically distinct therapeutic modality. This review synthesizes clinical progress of OVs in GBM, with emphasis on oncolytic herpes simplex virus (oHSV) and coverage of other vectors (adenovirus, reovirus, Newcastle disease virus, vaccinia virus) across phase I–III trials, focusing on efficacy and safety. Key observations include the encouraging clinical trajectory of oHSV exemplars—T-VEC (approved for melanoma) and G47Δ (approved in Japan for recurrent GBM)—the multi-center exploration of the adenovirus DNX-2401 combined with programmed death-1 (PD-1) blockade, and the early-stage status of reovirus (pelareorep) and Newcastle disease virus programs. Emerging evidence indicates that oHSV therapy augments immune infiltration within the tumor microenvironment and alleviates immunosuppression, with synergy when combined with chemotherapy or immune checkpoint inhibitors. Persistent challenges include GBM’s inherently immunosuppressive milieu, limitations imposed by the blood–brain barrier, intrapatient viral delivery and biodistribution, and concerns about viral shedding. Future directions encompass programmable vector design, optimization of systemic delivery, biomarker-guided patient selection, and rational combination immunotherapy. Collectively, OVs represent a promising immunotherapeutic strategy in GBM; further gains will hinge on vector engineering and precision combinations to translate mechanistic promise into durable clinical benefit.
