Primary hepatic gastrointestinal stromal tumours (PHGISTs) are rare and frequently misdiagnosed due to their atypical presentation and uncertain origin. The purpose of this article is to present the case of a 79-year-old female patient with a gigantic PHGIST characterized by a predominantly cystic nature—an extremely rare presentation, as most cases of PHGIST are solid. Despite extensive imaging and exploratory laparotomy, the primary origin remained uncertain, leading to questioning about whether it was a true primary hepatic GIST or an atypical metastatic lesion. The initial therapeutic approach involved a surgical procedure aimed to confirm the diagnosis and achieve reductive tumourectomy. Following the surgery, the patient was administered imatinib with a favourable clinical response for four and a half years—an atypical pattern of resistance, as most patients typically develop therapeutic resistance within two to three years. A second surgical intervention was performed to address a cystic lesion localized in the left hepatic lobe, followed by an atypical segment III hepatectomy to achieve macroscopic resection. Subsequently, the patient received sunitinib for two and a half years, which resulted in temporary disease stabilization. However, the sunitinib treatment was associated with hypertension and leukopenia. The patient’s overall survival was 8 years, suggesting that individualized therapeutic strategies and close monitoring might be the key in such cases. Furthermore, this case confirms the role of surgical intervention even in advanced disease stages, with multiple major resections contributing significantly to prolonged survival. The interplay between surgical and oncologic therapies remains essential to guiding clinical decisions. Given the unusual cystic presentation, this case highlights the necessity to expand the pathological and molecular profiling of PHGISTs. Furthermore, the atypical timeline of resistance development and treatment-related toxicity emphasizes the importance of further research into the genetic and pharmacological determinants of PHGISTs. These findings advocate for the refinement of diagnostic, therapeutic, and surveillance protocols tailored to rare GIST subtypes. Full article

Exposure to high-linear energy transfer (LET) heavy ions, such as ²⁸Si, poses a significant cancer risk for astronauts. While previous studies have linked high-LET radiation exposure to persistent oxidative stress and dysregulated stress responses in intestinal crypt cells with an increased risk of tumorigenesis, the relationship between IR-induced oxidative DNA damage and intestinal cancer risk remains incompletely understood. Here, we investigated the time-dependent effects of ²⁸Si-ion radiation on intestinal tumorigenesis and oxidative DNA damage in Apc^1638N/+ mice, a model for human intestinal cancer predisposition. Male Apc^1638N/+ mice were exposed to 10 cGy of either γ-rays (low-LET) or ²⁸Si-ions (high-LET), and intestinal tumor burden was assessed at 60 and 150 days post-irradiation. While both radiation groups showed modest, non-significant tumor increases at 60 days, ²⁸Si-irradiated mice exhibited an approximately 2.5-fold increase in tumor incidence by 150 days, with a higher incidence of invasive carcinomas compared to γ and sham groups. Serum 8-OxodG levels, a marker of systemic oxidative stress, were significantly elevated in the ²⁸Si-ion group, correlating with increased intestinal 8-OxodG staining. Additionally, assessment of the proliferation marker Cyclin D1 and metaplasia marker Guanylyl Cyclase C (GUCY2C) also revealed significant crypt cell hyperproliferation accompanied by increased metaplasia in ²⁸Si-exposed mouse intestines. Positive correlations between serum 8-OxodG and tumor-associated endpoints provide compelling evidence that exposure to ²⁸Si-ions induces progressive intestinal tumorigenesis through sustained oxidative DNA damage, crypt cell hyperproliferation, and metaplastic transformation. This study provides evidence in support of the radiation quality-dependent progressive increase in systemic and intestinal levels of 8-OxodG during intestinal carcinogenesis. Moreover, the progressive increase in oxidative DNA damage and simultaneous increase in oncogenic events after ²⁸Si exposure also suggest that non-targeted effects might be a significant player in space radiation-induced intestinal cancer development. The correlation between serum 8-OxodG and oncogenic endpoints supports its potential utility as a predictive biomarker of high-LET IR-induced intestinal carcinogenesis, with implications for astronaut health risk monitoring during long-duration space missions.

This systematic review and meta-analysis evaluates (1) the effectiveness of psychedelic-assisted therapy (PAT) using psilocybin and ketamine for psychosocial symptoms in adults with cancer, (2) contextualizes findings with non-randomized and exploratory studies of other psychedelics, and (3) examines the role of therapeutic frameworks in shaping outcomes. We searched PubMed, Cochrane Library, PsycINFO, and EMBASE (2000–2024) for randomized controlled trials (RCTs) and non-randomized studies investigating psychedelic agents in cancer populations. Meta-analyses pooled RCTs of psilocybin or ketamine using random-effects models. Non-randomized studies were synthesized narratively. Risk of bias and evidence certainty were assessed via Cochrane ROB 2.0, NIH Before–After tool, and GRADE. Eleven placebo-controlled RCTs and four single open-label studies were included. Meta-analysis of four ketamine RCTs (n = 354) showed large, rapid effects on depression/anxiety (Hedges’ g = −1.37, 95% CI: −2.66 to −0.08; I² = 92%). Three psilocybin RCTs (n = 101) showed a large effect of psilocybin on alleviating depression (Hedges’ g = −3.13, 95% CI: −10.04 to 3.77; I² = 95%). MDMA and LSD trials suggested promise but lacked rigor. PAT may offer meaningful relief for cancer-related distress, though effects vary by therapeutic model and context. Oncology-specific trials are needed to standardize and scale for implementation. Full article

Background: Quality of life (QoL) is a critical indicator in assessing the success of oncological treatments for head and neck malignancies, reflecting their impact on physiological functions and psychosocial well-being beyond mere survival. Treatments (surgery, radiotherapy, chemotherapy) pose multiple functional and emotional challenges, and recent advancements underscore the necessity of evaluating post-treatment QoL. Objective: This literature review investigates the impact of oncological treatment on the QoL of patients with malignant head and neck cancers (oral, oropharyngeal, hypopharyngeal, laryngeal) and identifies factors influencing their QoL index. Methodology: Using a PICO framework, studies from PubMed Central were analyzed, selected based on inclusion (English publications, full text, PROM results) and exclusion criteria. The last research was conducted on 6 April 2025. From 231 identified studies, 49 were included after applying filters (MeSH: “Quality of Life,” “laryngeal cancer,” “oral cavity cancer,” etc.). Data were organized in Excel, and the methodology adhered to PRISMA standards. Results: Treatment Impact: Oncological treatments significantly affect QoL, with acute post-treatment declines in functions such as speech, swallowing, and emotional well-being (anxiety, depression). Partial recovery depends on rehabilitative interventions. Influencing Factors: Treatment type, disease stage, socioeconomic, and demographic contexts influence QoL. De-escalated treatments and prompt rehabilitation improve recovery, while complications like trismus, dysphagia, or persistent hearing issues reduce long-term QoL. Assessment Tools: Standardized PROM questionnaires (EORTC QLQ-C30, QLQ-H&N35, MDADI, HADS) highlighted QoL variations. Studies from Europe, North America, and Asia indicate regional differences in outcomes. Limitations: Retrospective designs, small sample sizes, and PROM variability limit generalizability. Multicentric studies with extended follow-up are recommended. Conclusions: Oncological treatments for head and neck malignancies have a complex impact on QoL, necessitating personalized and multidisciplinary strategies. De-escalated therapies, early rehabilitation, and continuous monitoring are essential for optimizing functional and psychosocial outcomes. Methodological gaps highlight the need for standardized research. Full article

(1) Background: Lymphedema is a common but underrecognized sequela of cancer treatment. Supermicrosurgical procedures such as lymphaticovenular anastomosis (LVA) and, more recently, lymph node-to-vein anastomosis (LNVA) have emerged as effective options for fluid-predominant disease. In 2024, we began performing robot-assisted LNVA using a next-generation microsurgical robot. This study describes our initial experience, technical insights, and the potential for robotics to extend the boundaries of supermicrosurgery. (2) Methods: Twenty-two consecutive robotic LNVAs were performed by a high-volume supermicrosurgeon at a tertiary center. Preoperative imaging with standard and ultra-high frequency ultrasound was used to identify optimal lymph nodes and veins. Robotic LNVA was performed using the Symani Surgical System, with adaptations for motion scaling, ergonomics, and console control. Intraoperative patency was confirmed by direct washout and/or indocyanine green (ICG) transit. (3) Results: All 22 procedures were technically successful, with 100% intraoperative patency. Anastomosis time improved from 37 to 18 min. Robotic assistance enhanced precision, eliminated tremors, and reduced the technical burden of operating at extreme submillimeter scales. (4) Conclusions: Robotic LNVA is safe, feasible, and efficient. It optimizes current techniques, offering the potential to extend surgical access below the 0.1 mm threshold, with implications for future treatment of lymphatic and possibly intracranial disease.

Objective: This study compares the surgical and oncological outcomes of minimally invasive robotic (RLP) and laparoscopic (LLP) left pancreatectomy in pancreatic cancer (PC) patients. Methods: Data from patients who underwent minimally invasive left pancreatectomy between 2013 and 2023 were analyzed. Two groups were identified: RLP and LLP. Perioperative outcomes were compared, including operative time, blood loss, conversion rate, and postoperative complications. Oncological outcomes included margin status, lymph node retrieval, lymph node status, overall survival (OS), and disease-free survival (DFS). Results: Fifty-four patients were divided into the LLP (n = 39) and RLP (n = 15) groups. The median operative time was shorter for LLP than RLP [260 min vs. 366 min, p = 0.007]. Blood loss and conversion rates were comparable (p > 0.05). In the LLP group, significantly more lymph nodes were harvested (29 vs. 19, p = 0.05), and a higher percentage of positive lymph nodes was noted (72% vs. 40%, p = 0.033). No significant difference was found in the R0 resection status (82% vs. 73%, p = 0.358). After a median follow-up of 26 months, OS (23 months vs. 34 months, p = 0.812) and DFS (17 months vs. 16 months, p = 0.635) were similar. Conclusion: RLP provides outcomes identical to LLP in treating body–tail pancreatic cancer, with further studies needed to confirm its long-term oncological efficacy. Full article

The 2018 Farm Bill legalized hemp-derived cannabidiol (CBD) products containing less than 0.3% tetrahydrocannabinol (THC) in the United States. This legislative shift catalyzed both public and scientific interest in CBD’s potential health benefits. However, the rapid expansion of the CBD market has considerably outpaced rigorous scientific research, leaving many health claims largely unsubstantiated. While preclinical studies suggest that CBD may exert antitumorigenic effects in colorectal cancer (CRC) by modulating cell proliferation, apoptosis, and inflammation, clinical evidence supporting these effects remains limited. This review critically examines the current evidence on the role of CBD in colorectal tumorigenesis, with particular attention to its molecular mechanisms and interactions with the serotonergic system—a signaling pathway implicated in the development of CRC and possessing potential dual anti- and pro-tumorigenic properties. By influencing the serotonergic system, CBD may confer both protective and potentially deleterious effects during CRC development. This review underscores the need for further research to elucidate the complex mechanisms of CBD in colorectal tumorigenesis and to evaluate its therapeutic potential in clinical settings. Understanding these interactions could pave the way for novel prevention and treatment strategies, optimizing the anticancer efficacy of CBD while mitigating unintended risks. Full article

Background: Local recurrence for high-risk extremities/trunk soft tissue sarcoma (STS) after treatment can range from 15 to 30%. The modified Eilber protocol (MEP) using low-dose intravenous chemotherapy with a reduced dosage of radiation in the preoperative setting has demonstrated excellent local control and reduced wound complications in these patients. The aim of the current study was to assess long-term local control and overall survival in patients with STS treated with the MEP versus standard preoperative or postoperative radiotherapy. Methods: Patients diagnosed with STS from 2004 to 2016 were identified using the Alberta Cancer Registry. Patients with STS treated with the MEP, preoperative or postoperative radiotherapy, were included. Patient and tumor characteristics, treatments and outcomes were abstracted from the registry and primary chart review. Characteristics were compared using one-way ANOVA for continuous variable and chi-square test and Fisher test for the categorical outcomes. Local recurrence-free survival and overall survival were analyzed using Kaplan–Meier Analysis with Log-rank test. Results: A total of 242 patients with STS were included, among which 100 (41.3%) received the MEP prior to surgery, 91 (37.6%) had preoperative radiation, and 51 (21.1%) had postoperative radiation. After a median follow up of 4.9 years, there were no significant differences in local recurrence or local recurrence-free survival between patients treated with the MEP vs. preoperative or postoperative radiotherapy (10 vs. 6.6% and 7.8%, respectively, p-value NS). There were also no significant differences between groups for recurrence-free survival and overall survival. Conclusions: This study demonstrates that the use of the MEP has non-inferior oncologic outcomes compared to standard preoperative or postoperative radiation in a population-based analysis despite reducing the overall dosage of radiation administered. The modified Eilber preoperative chemoradiation protocol may be considered as an additional option for patients with STS. Full article

Immunotherapy has a defined role in the treatment of both early- and late-stage triple-negative breast cancer (TNBC) and is under active exploration in human epidermal receptor 2-positive as well as high-risk hormone-receptor-positive subtypes. It is critical to balance the efficacy and toxicity of immunotherapy while keeping the cost and duration of treatment in check. In addition to the immunohistochemistry testing of PD-L1 expression, which only predicts the efficacy of immunotherapy in metastatic TNBC, there is a lack of biomarkers that are better standardized to predict efficacy and treatment response, detect early relapse, and guide prognosis in breast cancer patients treated with immunotherapy. Circulating tumor DNA (ctDNA) is a minimally invasive, dynamic, real-time, blood-based biomarker that has shown promising value in the management of solid tumors, including breast cancer. This review discusses the emerging evidence for the potential application of ctDNA to further refine patient-centered care and personalize treatment based on a molecularly defined risk assessment for breast cancer patients treated with immunotherapy-based approaches. We further discuss the challenges and barriers to widespread adoption of this promising tool in the management of breast cancer patients requiring immunotherapy. Full article

Background: The geriatric nutritional risk index (GNRI), a composite metric of serum albumin and body weight, has emerged as a prognostic tool in various cancers. However, its relevance in nasopharyngeal carcinoma (NPC) patients treated with volumetric modulated arc therapy (VMAT) remains unexplored. The aim of this study was to assess the effect of the GNRI in the prediction of the prognosis of nasopharyngeal carcinoma in the era of VMAT. Methods: This retrospective study analyzed 498 newly diagnosed, non-metastatic NPC patients treated with VMAT between 2010 and 2011. The GNRI was calculated using serum albumin and body weight ratios, with receiver operating characteristic (ROC) curve analysis determining its optimal prognostic cutoff. Patients were stratified into training (70%) and validation (30%) cohorts. Cox regression identified independent prognostic factors, which were integrated into a nomogram predicting 3- and 5-year overall survival (OS). Model performance was assessed via the concordance index (C-index), calibration curves, and decision curve analysis (DCA). Results: In the study, 348 patients were included in the training cohort and 150 patients were included in the validation cohort according to a ratio of 7:3. The median follow-up was 68 months, with 5-year OS rates of 79.3%. A GNRI > 102 independently predicted improved survival (HR = 0.64; p = 0.044), alongside tumor volume, age, and N-stage. The nomogram demonstrated strong discrimination (C-index: 0.757–0.762 for training; 0.737–0.744 for validation) and calibration, aligning closely with observed survival. DCA confirmed superior clinical utility over default strategies. NPC patients treated with VMAT with a high GNRI, female sex, and a lower N-stage exhibited significantly better OS (p < 0.05). Conclusions: The GNRI is a robust prognostic marker for NPC patients receiving VMAT, reflecting the interplay of nutrition, inflammation, and treatment response. The validated nomogram provides a practical tool for individualized risk stratification, enhancing clinical decision-making in the era of precision radiotherapy. Full article

Background: The impact of adjuvant chemotherapy (AC) on outcomes in real-world patients with locally advanced rectal cancer (LARC) remains uncertain. Methods: Consecutive patients with LARC (stage II/III) undergoing neoadjuvant chemoradiation before curative-intent surgery from 2005 to 2013 were identified in the Canadian Health Outcomes Research Database. The impact of AC on clinical outcomes, including disease-free survival (DFS) and overall survival (OS), was evaluated using the Kaplan–Meier method and Cox proportional hazards modeling. Results: A total of 1448 patients had sufficient data available to be included for analysis with 1085 (74.9%) receiving AC. Of AC patients, 40.5% received oxaliplatin-based treatments. With a median follow-up of 66.43 months, the 5-year DFS rate was 67.7% (95% CI: 64.5–70.1%) vs. 58.7% (95% CI: 52.8–64.2%) in the AC group and non-AC group, respectively (p < 0.001). The 5-year OS rate of the whole cohort was 74.3% (95% CI: 71.5–76.85%) while the 5-year OS rate of the AC group was 77.8% (95% CI: 74.7–80.6%) compared with 63.8% (95% CI: 57.9–69.2%) for the non-AC group (p < 0.001). On multivariate analysis, patients who received AC had improved DFS (HR 0.6, 95% CI: 0.49–0.73, p < 0.001) and OS (HR 0.46, 95% CI: 0.36–0.58, p < 0.001). Conclusions: This large multi-institutional database analysis supports the use of AC in real-world LARC patients treated with nCRT followed by surgical resection. Full article

Colorectal cancer (CRC) is the third most common malignancy worldwide and the second leading cause of cancer-related mortality in the United States. The incidence of early-onset colorectal cancer (EOCRC) has been increasing over the past several decades. While the etiologies for this rising incidence remain unclear, genetic factors likely play an important role. DNA polymerase epsilon (POLE) mutations occur at a higher rate than average-onset colorectal cancer (AOCRC). DNA polymerase epsilon (Pol ε) is a high-fidelity, processive polymerase that is a promising target for immune checkpoint inhibitors due to its association with various human malignancies, including colorectal cancer. EOCRC remains a major area of focus, and POLE mutations leading to the high-TMB subtype constitute a potential therapeutic target. Full article

Purpose: Cancer treatments can result in subfertility or infertility in female adult childhood cancer survivors (ACCSs). While ACCSs may utilize assisted reproductive technology (ART) or other family-building options, the limited evidence describing their experiences remains a hindrance to developing and implementing appropriate patient-centered supports. The study’s aim is to describe the challenges female ACCSs experienced while navigating ART and family-building options, to inform improvements in clinical practice in a western Canadian province. Methods: In this qualitative Interpretive Description study, interviews were conducted with 15 female ACCSs and data were analyzed using an interpretive thematic approach and constant comparative techniques. Results: ACCSs’ narratives suggest they experienced five prominent challenges while navigating ART and family-building options, including (1) confronting unexpected, impaired fertility, (2) grieving loss and redefining identity, (3) encountering unsupportive healthcare, (4) exploring alternative paths of adoption and international family-building, and (5) facing financial strain. Conclusions: This exploratory study provides initial insights into the significant and multifaceted challenges female ACCSs experience related to family building and highlights gaps in healthcare services. Further research is warranted to articulate these challenges across contexts and the development and implementation of mitigating approaches. Implications for Cancer Survivors: The integration of comprehensive informational, psychosocial, and financial supports into existing cancer survivor and family-building services is vital to meeting female ACCSs’ unmet needs.

Purpose: Current yoga programs for cancer survivors do not meet participants’ needs and are rarely implemented in community-based settings, despite reported benefits. The aim of the current study was to implement a co-created 12-week bi-modal Hatha-based yoga program for adults diagnosed with gynecologic cancer in the community and assess the feasibility and acceptability of the program and study methods. Methods: Using a mixed methods series N-of-1 A₁BA₂ research design, participants were recruited from The Ottawa Hospital. Participants self-selected a morning or evening program, completed surveys 9 to 11 times and were interviewed post-program. The yoga instructor was interviewed post-program about her experience delivering the program. Quantitative feasibility outcomes were tracked throughout the study. Qualitative acceptability outcomes were explored during post-program semi-structured interviews. Audio and video recordings of the yoga classes and data from the instructor interview were used to assess fidelity outcomes to determine whether the protocol could be adhered to consistently. Results: Forty-one individuals were screened for eligibility and 20 consented (48.7%). Seventeen participants (85.0%) completed the final survey. Participants attended 83.1% (19.9/24) of classes with varied engagement with optional features. The instructor was 61.3% adherent to the prescribed protocol, using recommended behaviors 44.6% of the time. Participants shared barriers and facilitators that influenced the success of the trial methods and program. Conclusions: The program was well-received and trial methods were moderately successful, but refinements are warranted before a large-scale trial. Community-based yoga programs could be feasible and acceptable for women with gynecologic cancer. Full article

Non-small cell lung cancer (NSCLC) remains a major contributor to cancer-related deaths worldwide, with therapeutic resistance presenting a critical clinical hurdle. The DNA damage response (DDR) constitutes a sophisticated cellular framework that detects, signals, and repairs genetic lesions to preserve genomic stability. While the DDR plays a crucial role in determining the efficacy of radiotherapy and chemotherapy, current research primarily focuses on direct DDR inhibitors, often overlooking the broader regulatory networks that modulate DDR activity. This review aims to comprehensively analyze the upstream and downstream pathways governing DDR in NSCLC, highlighting key molecular regulators, signaling interactions, and potential feedback mechanisms contributing to therapy resistance. By identifying novel regulatory targets and clinically relevant biomarkers, we propose innovative therapeutic strategies to enhance treatment efficacy. Our approach seeks to bridge the gap between DDR dysregulation and precision oncology, offering new perspectives on overcoming resistance and improving patient outcomes in NSCLC. Full article

Small cell lung cancer (SCLC) is an aggressive form of lung cancer characterized by rapid growth and early metastases. As a neuroendocrine tumour, SCLC is especially notorious for various paraneoplastic syndromes, one of which is a rare neurological syndrome called paraneoplastic limbic encephalitis (PLE) that manifests with amnestic cognitive impairment and seizures. Here, we describe a case of a 53-year-old female who presented with neuropsychiatric symptoms of delusions, hallucinations, and cognitive impairment that started months prior to being diagnosed with extensive-stage SCLC. With no previous neuropsychiatric history, this raised the question of whether her presentation was related to PLE rather than a primary psychiatric condition, as initially diagnosed. Her symptoms improved with chemotherapy and radiation treatment of the underlying cancer, favouring a paraneoplastic etiology. Overall, this case underscores the importance of considering paraneoplastic syndromes in patients presenting with new neuropsychiatric symptoms, as early recognition and treatment can improve prognosis.

Recent research suggests a link between KRAS mutations and the effectiveness of ICIs, as KRAS-driven tumors may possess unique immunogenic features that influence the tumor microenvironment. These mutations can increase tumor mutation burden (TMB) and neoantigen load, potentially leading to improved responses to ICIs. This meta-analysis aims to consolidate existing evidence on the impact of KRAS mutations as a predictive factor for survival and treatment outcomes in patients with advanced NSCLC treated with ICIs. A comprehensive search strategy was designed by a biostatistician and pulmonologist, targeting PubMed, Web of Science, and Scopus databases up to May 2022. The outcomes assessed included overall survival (OS) and progression-free survival (PFS), reported as log hazard ratios (HRs) with corresponding standard errors (SEs). A pooled estimate of the HR effect size was calculated using Review Manager (RevMan, Cochrane Collaboration, London, UK). Heterogeneity among studies was evaluated using the Cochran Q test and the I² statistic. Ultimately, 10 articles were deemed suitable for inclusion in the systematic review from a total of 8722 screened titles and abstracts. The presence of KRAS+ mutations had a significant prognostic factor for better OS in NSCLC patients treated with checkpoint inhibitors (HR = 0.89, 95% CI: 0.79–0.99) and for better PFS in NSCLC patients treated with checkpoint inhibitors (HR = 0.72, 95% CI: 0.59–0.87). In conclusion, our study indicates that KRAS mutations may serve as a potential positive predictive biomarker in patients with advanced non-small-cell lung cancer treated with immune checkpoint inhibitor monotherapy.
