Soft tissue sarcoma (STS) has an 2–8% incidence for all malignant tumors in the adolescent and young adult (AYA) population, which are patients from ages 15 to 39. As most STS tumors are aggressive, they require multimodal management with surgery, radiation and chemotherapy. This article discusses the survivorship considerations in this young population of cancer patients who complete therapy. The lasting side effects include surgical and radiation-related morbidity, chemotherapy toxicity, early and late secondary effects on other organ systems, such as cardiac and endocrine dysfunction, and the development of secondary cancers. The long-term psychologic and practical impacts for those who have received a sarcoma diagnosis in the prime of their life include fertility, mental health, relationship, education and career implications. Although there is a paucity of data in some of these areas, we present existing management guidelines as available. This article serves as a comprehensive review of this wide array of treatment effects intended for all providers participating in the care of AYA sarcoma survivors, to include oncologists, primary care providers and therapists.

Azacitidine and venetoclax (Aza-Ven) are part of a new standard of care for elderly patients with Acute Myeloid Leukemia (AML) [In line with recommendations, patients with AML at our centre were routinely admitted during initiation of Aza-Ven for close monitoring for tumour lysis syndrome (TLS). However, hospitalization impacts patient experience and is a significant resource burden. The objectives of this study were to evaluate the incidence of TLS in this population and identify patients who could safely initiate therapy in our outpatient facility. Of the 48 patients who commenced Aza-Ven as inpatients, the incidence of TLS was 25% using Cairo–Bishop (CB) diagnostic criteria but was mostly due to transient increases in uric acid, phosphate or potassium that remained within the normal laboratory reference range. Using Howard diagnostic criteria, TLS incidence was only 2%. Patients who developed CB TLS had a significantly higher baseline white blood count (WBC; p = 0.01). Patients with WBC of less than 30 × 10⁹/L subsequently completed outpatient initiation of Aza-Ven (n = 15). Only one of these patients developed mild, transient TLS by CB criteria but not by Howard criteria. Our results demonstrate that a significant portion of patients could safely initiate Aza-Ven in our outpatient facility and avoid unnecessary hospitalization. Full article

Purpose: This study aimed to compare long-term patient-reported outcomes in bowel and urinary domains between intensity-modulated radiotherapy (IMRT) and intensity-modulated proton therapy (IMPT) for localized prostate cancer. Methods and Materials: Patients with clinical T1–T2 prostate cancer receiving IMRT or IMPT at a tertiary cancer center from 2015–2018 were analyzed to determine the changes in the prospectively collected bowel function (BF), urinary irritative/obstructive symptoms (UO), and urinary incontinence (UI) domains of EPIC-26. The mean changes in EPIC-26 scores were evaluated from pretreatment to 24 months post-radiotherapy for each modality. A score change >50% of the baseline standard deviation was considered a clinically meaningful change. Results: A total of 82 patients treated with IMRT (52.2%) and 56 patients treated with IMPT (53.3%) completed the questionnaire at baseline and 24 months post-RT. There were no baseline differences in domain scores between treatment modalities. At 24 months post-radiotherapy, there was a significant and clinically meaningful decline in the BF mean score in the IMRT cohort (−4.52 (range −50, 29.17), p = 0.003), whereas the decline in BF score did not reach clinical relevance or significance (−1.88 (range −37.5, 50), p = 0.046) when accounting for the Bonferroni adjustment in the IMPT cohort. A higher proportion of patients treated with IMRT had a clinically relevant reduction in BF when compared with IMPT (47.37% vs. 25.93%, p = 0.017). The mean changes in the UI and UO scores of the IMRT and IMPT cohorts were neither statically significant nor clinically relevant. Conclusions: IMPT leads to a smaller decrease in BF than IMRT at 24 months post-RT, while there was no differential effect on UO and UI. Full article

(1) Background: It is controversial if Merkel cell carcinomas (MCCs) spread to lymph nodes or distant metastases (LNM/DM) first. (2) Methods: A total of 303 patients from six institutions (March 1982–February 2015) were combined with individual patient data from a PubMed search, totaling 949 patients. The primary outcome was recurrence patterns. (3) Results: (a) More patients presented with lymph node metastases (LNMs) than DMs at diagnosis: 17.9% (166 among the 929 patients with known staging) vs. 1.9% (18/929); (b) 310/929 (33.4%) developed lifetime DM, of whom 220/310 also developed LNM. The majority (133 patients) of patients were documented to have developed LNM before DM. (c) A shorter median time of 1.5 months (range: 0–47.0) from initial diagnosis to LNM, versus 8 months (range: 0–107.8) to DM, was also found. Another observation was that 2.4% (23/949) of patients with primary tumors ≤1 cm developed lifetime DM, with the smallest being 0.2 cm. (4) Conclusions: Three observations support the idea that prior LNM gives rise to subsequent DM as the main pathway of dissemination in MCC. This implies that patients with nodal metastases should be considered for adjuvant systemic therapy studies as an enriched population. Participation in clinical trials is strongly encouraged.

Fear of cancer recurrence (FCR) affects approximately 50% of family caregivers. While FCR in cancer patients has been well-documented, less is known about the experience of FCR in family caregivers. This study aimed to qualitatively explore the distinct characteristics of FCR in family caregivers. A focus group and semi-structured interviews were conducted via videoconferencing with family caregivers of cancer survivors (stages I–III, finished treatment, no recurrence). Participants were recruited through Canadian hospitals, community partners, and social media. The focus group and qualitative interviews explored family caregivers’ experiences of FCR, including its content, frequency, impact, and management. A reflexive thematic analysis was used. In total, twenty family caregivers participated. Six participated in the focus group. Sixteen participated in the interviews. Two participated in both. Family caregivers described their experience of FCR as all-consuming, constant, and marked by a sense of helplessness. Qualitative analysis revealed a major theme of relational aspects of FCR in family caregivers, with the following four inter-related themes: patient-centric hypervigilance, self-silencing, FCR as isolating, and finding support. This qualitative study examined the experiences of family caregivers living with FCR. Our findings highlight that relational factors shape how family caregivers experience and manage their FCR. High-quality survivorship care should be redefined to include FCR interventions tailored to family caregivers. Full article

Despite advances in treatment, recurrence rates in oral squamous cell carcinoma (OSCC) remain high. Prognostic outcomes vary in terms of local recurrence, metastasis, and overall survival. A retrospective cohort analysis was conducted on OSCC patients who underwent primary surgery at the Department of Craniomaxillofacial and Facial Plastic Surgery, University Medical Center Frankfurt, between January 2014 and December 2020. Demographic data, tumor characteristics, surgical details, intraoperative frozen section results, and recurrence patterns were first assessed for availability. Subsequently, the available data relevant to each endpoint were analyzed. A total of 169 patients were analyzed (mean age: 64 years). The tongue was the most affected site and had the highest recurrence rate, followed by the floor of the mouth. Overall, 24.3% of patients experienced recurrence, with most cases occurring within the first year. T2 tumors had the highest recurrence rates. Between patients with and without adjuvant therapy, recurrence rates were comparable. Positive surgical margins were more common in recurrence cases, but no significant correlation was found between margin status and recurrence in patients without adjuvant therapy. Based on the analyzed data, achieving recurrence-free survival in OSCC does not solely depend on surgical technique or adjuvant therapy. Instead, early recognition of individual tumor characteristics and even tumor biology should guide personalized treatment planning. Notably, tumors of the tongue and floor of the mouth exhibited high recurrence rates regardless of disease stage, raising the question of whether primary chemoradiotherapy (CRT) could achieve better outcomes than surgery. Further studies are needed to evaluate the role of CRT as a first-line treatment for OSCC in these locations. Full article

Glioblastoma is the most common and aggressive malignant brain tumor in adults, with an increasing incidence and a poor prognosis. Current challenges in glioblastoma management include rapid tumor growth, limited treatment effectiveness, high recurrence rates, and a significant impact on patients’ quality of life. Given the complexity of glioblastoma care and recent advancements in diagnostic and treatment modalities, updated guidelines are needed in Canada. This Delphi study aimed to develop Canadian consensus recommendations for the diagnosis, classification, and management of newly diagnosed and recurrent glioblastoma. A multidisciplinary panel of 14 Canadian experts in glioblastoma care was convened, and a comprehensive literature review was conducted to synthesize evidence and formulate initial recommendations. Consensus was achieved through three Delphi rounds, in which panelists rated their agreement with recommendation statements on a five-point Likert scale. Statements with ≥75% agreement were accepted, and others were revised for re-voting. Final recommendations were formulated based on the consensus level, strength of evidence, clinical expertise, and consideration of the Canadian healthcare context. These recommendations aim to standardize glioblastoma diagnosis and classification across Canada, provide evidence-based guidance for optimal treatment selection, integrate novel therapies, and enhance the overall quality of care for glioblastoma patients.

Lung cancer remains the leading cause of cancer-related mortality worldwide, with non-small-cell lung cancer (NSCLC) accounting for the majority of the cases. Despite advancements in targeted therapies and immunotherapies, many patients still rely on chemotherapy, highlighting the need for innovative treatment strategies. Bispecific antibodies (bsAbs), which feature two distinct binding sites capable of targeting different antigens, have emerged as a promising therapeutic approach, particularly in combination with chemotherapy. This review explores the scientific evolution and clinical application of bsAbs in NSCLC, focusing on their synergistic potential with chemotherapy. BsAbs, such as amivantamab, which targets EGFR and MET, have demonstrated significant efficacy in clinical trials, particularly in patients with EGFR mutations. The combination of bsAbs with chemotherapy enhances immune-mediated tumor destruction by modulating the tumor microenvironment and overcoming resistance mechanisms. Recent clinical trials have shown improved progression-free survival and overall survival when bsAbs such as amivantamab are combined with chemotherapy, underscoring their potential to transform NSCLC treatment. Many other clinical trials are underway that are evaluating newer bsAbs, such as ivonescimab, which targets PD1 and VEGF. This review also discusses ongoing clinical trials investigating various bsAbs targeting EGFR, PD-1, PD-L1, HER2, and other pathways, highlighting the future directions of bsAb-based therapies. As the field evolves, bsAbs are poised to become a cornerstone of multimodal NSCLC treatment, offering more effective and personalized therapeutic options for patients with advanced disease.

Ectopic adrenocorticotropic hormone syndrome (EAS) occurs when a tumor develops neuroendocrine differentiation with the secretion of ACTH resulting in hypercortisolism and possibly Cushing’s syndrome (CS). Only 5–10% of CS cases are attributed to EAS; of these, breast tumors comprise less than 1%. Two known variants of breast neuroendocrine tumors include neuroendocrine-differentiated carcinoma and ductal carcinoma with neuroendocrine features. Currently, guidelines for treatment are limited and EAS is associated with significant morbidity and mortality. A 39-year-old female presented with a rapidly enlarging breast mass. Biopsy demonstrated invasive poorly differentiated breast carcinoma with high-grade neuroendocrine features and necrosis. Staging at diagnosis confirmed metastatic disease of the liver and bone. First-line chemotherapy (Cisplatin/Etoposide/Durvalumab) was initiated with evidence of disease progression after four cycles. Given a poor response to therapy, a simple mastectomy was performed for local control and complete pathologic analysis, demonstrating high-grade neuroendocrine carcinoma with large-cell features. Second-line therapy (Adriamycin/Cyclophosphamide) was initiated for three cycles after which the patient required admission for severe and refractory hypokalemia. Workup confirmed elevated ACTH consistent with paraneoplastic EAS and further evidence of disease progression. Third-line therapy (Nab-Paclitaxel) was initiated, and genetic testing was completed, confirming the PIK3 mutation, for which access to Alpelisib therapy was requested. Given symptoms of progressive severe CS with significant liver disease limiting medical therapies, the patient underwent urgent bilateral laparoscopic adrenalectomy after which she was able to be discharged home while awaiting additional systemic therapy. EAS resulting in CS secondary to breast neuroendocrine carcinoma is a rare and challenging diagnosis. Further research is needed to inform treatment guidelines to improve outcomes. While patient survival is dependent upon the underlying disease process, laparoscopic bilateral adrenalectomy is an accepted, definitive treatment option. Full article

Biological sex and gender factors significantly influence the pathogenesis, progression, and treatment response in hematologic malignancies. This comprehensive review examines sex-specific differences in acute myeloid leukemia, acute lymphoblastic leukemia, chronic myeloid leukemia, and multiple myeloma through systematic analysis of the peer-reviewed literature published between 2014–2024 and identified through structured searches of PubMed, Web of Science, and MEDLINE databases. Epidemiological data demonstrate higher disease incidence (57% male vs. 43% female in MM, 63% male vs. 37% female in AML hospitalizations for ages 18–39) and inferior outcomes in male patients across malignancy types (5-year relative survival rates of 48.8% vs. 60.4% in females with AML), while female patients exhibit superior survival despite experiencing greater treatment-related toxicities. Our analysis reveals consistent sex-specific patterns in molecular mechanisms, including distinct mutational profiles, differences in immune system function, and sex-based pharmacokinetic variations that collectively suggest the necessity for sex-differentiated treatment approaches. The review identifies reproducible patterns across diseases, particularly in cytogenetic and molecular characteristics, with females demonstrating favorable prognostic mutations in leukemias and higher rates of chromosomal abnormalities in multiple myeloma. Despite these identifiable patterns, significant knowledge gaps persist regarding the underlying mechanisms of sex-based outcome differences. Incorporating sex and gender considerations into precision medicine frameworks represents a critical advancement toward optimizing treatment strategies and improving clinical outcomes for patients with hematologic malignancies.

Neuropilin-1 (NRP1), initially identified as a neuronal guidance protein, has emerged as a multifaceted regulator in cancer biology. Beyond its role in axonal guidance and angiogenesis, NRP1 is increasingly recognized for its significant impact on tumor progression and therapeutic outcomes. This review explores the diverse functions of NRP1 in cancer, encompassing its influence on tumor cell proliferation, migration, invasion, and metastasis. NRP1 interacts with several key signaling pathways, including vascular endothelial growth factor (VEGF), semaphorins, and transforming growth factor-beta (TGF-β), modulating the tumor microenvironment and promoting angiogenesis. Moreover, NRP1 expression correlates with poor prognosis in various malignancies, underscoring its potential as a prognostic biomarker. Therapeutically, targeting NRP1 holds promise as a novel strategy to inhibit tumor growth and enhance the efficacy of regular treatments such as chemotherapy and radiotherapy. Strategies involving NRP1-targeted therapies, including monoclonal antibodies, small molecule inhibitors, and gene silencing techniques, are being actively investigated in preclinical and clinical settings. Despite challenges in specificity and delivery, advances in understanding NRP1 biology offer new avenues for personalized cancer therapy. Although several types of cancer cells can express NRPs, the role of NRPs in tumor pathogenesis is largely unknown. Future investigations are needed to enhance our understanding of the effects and mechanisms of NRPs on the proliferation, apoptosis, and migration of neuronal, endothelial, and cancer cells. The novel frameworks or multi-omics approaches integrate data from multiple databases to better understand cancer’s molecular and clinical features, develop personalized therapies, and help identify biomarkers. This review highlights the pivotal role of NRP1 in cancer pathogenesis and discusses its implications for developing targeted therapeutic approaches to improve patient outcomes, highlighting the role of OMICS in targeting cancer patients for personalized therapy.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are effective in non-small-cell lung cancer (NSCLC) with sensitizing mutations. However, patients with uncommon EGFR mutations show variable responses, and resistance often develops. The C797S mutation is a common resistance mechanism after third-generation EGFR-TKI osimertinib therapy, with no standard treatment established. A 37-year-old Chinese woman with advanced NSCLC harboring EGFR G719S/S768I mutations developed an acquired C797S mutation without T790M after second- and third-generation EGFR-TKI therapy. She was treated with a combination of gefitinib and bevacizumab, achieving a partial response, particularly in liver metastases. Her overall survival exceeded 60 months. Gefitinib combined with bevacizumab demonstrates efficacy in managing NSCLC with uncommon EGFR mutations and overcoming acquired C797S resistance. This combination therapy offers a promising treatment strategy for patients with limited options after resistance to second- and third-generation EGFR-TKIs. Full article

(1) Background: Knowledge regarding the optimal radiotherapy dose for Merkel-cell carcinoma (MCC) remains limited. (2) Methods: Following a PubMed search, equivalent doses in 2 Gy fractions (Gy2) were compared. (3) Results: Of the 949 patients, 939 were evaluable, with 728 (77.5%) cases localized to the primary site and 171 irradiated without chemotherapy. The overall local recurrence rate (LRR) was 23% (40/171). After definitive radiotherapy with EQD2 < 50 Gy2 versus ≥50 Gy2, the LRRs were 23.1% (3/13) and 12.5% a(1/8), respectively (p = 0.0004). (4) Conclusions: For definitive radiotherapy, EQD2 < 50 Gy2 demonstrates a significantly higher LRR than ≥50 Gy2 (p = 0.0004). This study is clinically useful and unique with stratification by definitive/adjuvant settings and positive/negative resection margins. A future prospective multicenter study is needed to determine the optimal radiotherapy doses. Full article

Introduction: Biliary tract cancers (BTC) comprise a heterogeneous group of malignancies, including gallbladder cancer, intrahepatic cholangiocarcinoma, and extrahepatic cholangiocarcinoma. The main determinants of prognosis in BTC are the stage of the disease and the eligibility for curative treatment. Additionally, liver functional capacity is also one of the factors influencing survival in biliary tract cancers. The age–bilirubin–INR–creatinine (ABIC) score has been previously shown to predict prognosis in hepatic diseases. The aim of our study is to demonstrate the relationship between the ABIC score and prognosis in BTC. Materials and Methods: In this study, a retrospective analysis was performed on 41 patients with non-metastatic BTC and 73 patients with metastatic BTC who were followed up in our clinic between 2003 and 2025. All patients were ≥18 years old at the time of diagnosis, and BTC was pathologically confirmed. The ABIC score was calculated separately for each group. A threshold value for the ABIC score was determined using Receiver Operating Characteristic (ROC) analysis, and based on this threshold, patients were divided into low and high ABIC score groups. Both the relationship between the ABIC score and prognosis and the other factors affecting prognosis were investigated. Results: In the non-metastatic BTC group, the cutoff value for the ABIC score was 6.89. The median survival time of patients with a high ABIC score was significantly shorter. In the metastatic BTC group, the cutoff value for the ABIC score was 7.41. Similarly, in this group, patients with a high ABIC score had a significantly shorter median survival time. Additionally, in the non-metastatic BTC group, tumor localization and stage were prognostic factors affecting survival, while in the metastatic BTC group, CEA and first-line chemotherapy were the prognostic factors influencing overall survival. Conclusions: We demonstrate that the ABIC score is a prognostic factor determining median survival in both non-metastatic and metastatic BTC patients. Full article
