Person-centered navigation (PCN) in healthcare refers to a proactive collaboration among professionals, researchers, patients, and their families to guide individuals toward timely access to screening, treatment, follow-up, and psychosocial support. PCN—which includes professional, peer, and virtual guidance, is particularly crucial for rare cancers, where affected individuals face uncertainty, limited support, financial strain, and difficulties accessing relevant information, testing, and other services. The Canadian Cholangiocarcinoma Collaborative (C3) prioritizes PCN implementation to address these challenges in the context of Biliary Tract Cancers (BTCs). C3 uses a virtual PCN model and staffs a “C3 Research Navigator” who provides clinical and research navigation such as personalized guidance and support, facilitating access to molecular testing, clinical trials, and case reviews through national multidisciplinary rounds. C3 also supports a national network of BTC experts, a patient research registry, and advocacy activities. C3’s implementation strategies include co-design, timely delivery of support, and optimal outcomes across its many initiatives. Future priorities include expanding the C3 network, enhancing user engagement, and further integrating its innovative approach into routine care. Full article

Background: The identification of pathogenic variants in the Breast Cancer Genes 1 and 2 (BRCA1/2) is a critical predictive biomarker for poly (ADP-ribose) polymerase inhibitor (PARPi) therapy in epithelial ovarian cancer (EOC). The aim of this study is to define real-world rates and determinants of germline and somatic BRCA1/2 testing and subsequent PARPi utilisation in Australia using a national clinical quality registry. Methods: This multi-centre cohort study analysed data from 1503 women with non-mucinous EOC diagnosed between May 2017 and July 2022, captured by the Australian National Gynae-Oncology Registry (NGOR). We evaluated rates of germline and somatic testing and PARPi use, using multivariate logistic regression to identify associated clinical and demographic factors. Results: Overall germline and somatic testing rates were 68% and 32%, respectively. For the high-grade serous ovarian cancer (HGSOC) cohort, rates were higher, at 78% and 39%, respectively. Germline testing was significantly less likely for women aged >80 years (OR 0.49), those in regional areas (OR 0.61), and those receiving single-modality treatment. Somatic testing uptake increased significantly following public reimbursement for PARPi (p = 0.004). Among eligible women with a newly diagnosed BRCA pathogenic variant and advanced disease (n = 110), 52% commenced first-line maintenance PARPi. Conclusions: This national study offers valuable insights into Australian ovarian cancer care, highlighting opportunities to enhance testing equity for older women (aged >80) and regional patients. Furthermore, it identifies the translation of a positive test into PARPi therapy as a complex area that warrants further collaborative investigation to optimise patient outcomes. Full article

A comparative analysis of testicular tumors in dogs and humans highlights notable similarities in cancer behavior, particularly regarding environmental influences. The ubiquitous distribution of endocrine disruptors in industrialized countries and their effects are strongly linked to the development of testicular cancers. This study examined 221 and 174 cases of testicular tumor in dogs and humans, respectively, from the Campania Animal Cancer Registry and the database of the National Cancer Institute “Fondazione G. Pascale-IRCCS”, between 2020 and 2023. These data were integrated with environmental data from the Ministry of Environment and Energy Security website and the Campania Regional Agency for Environmental Protection (ARPAC). The areas with the highest frequency of testicular tumors in both species were the municipalities of Napoli, Salerno, and Caserta, and their corresponding provinces. The same locations experienced severe contamination of soil and water by environmental pollutants, probably correlated to testicular tumors. Although the molecular mechanisms are not yet fully understood, our data suggest a strong link between the frequency of testicular tumors in humans and dogs and high concentrations of environmental pollutants in the reported locations. These findings emphasize the value of dogs as a potential animal model for studying human health and the effect of environmental factors on cancer development. Full article

Background: It is estimated that in Italy, there were 364,000 new diagnoses of neoplasms each year and that the overall incidence of blood cancers was 10% of these. Leukemia and lymphomas represented the ninth and eighth places, respectively, among the causes of death from neoplasia. Hematopoietic stem cell transplantation represented an effective treatment option for many of these malignancies, and not only that: benign and congenital diseases could also be treated. Objective: To assess knowledge among the Apulian population regarding stem cell donation and factors that could influence this choice, focusing especially on the knowledge of the residents of Puglia, Italy on how stem cells were harvested and their functions, their reasons for joining the National Registry, and the reasons that hold them back from making such a choice. Study Design: An observational and cross-sectional study was conducted, through snowball sampling methodology, until data saturation. An online survey was conducted, which included several Italian associations. The questionnaire administered contained five main sections, such as sociodemographic data, knowledge of the existence of National Registries and their adherence, the nationwide presence of various associations that promote donation, knowledge with respect to the structure, use and functions of stem cells, sources of procurement, such as bone marrow, peripheral blood and umbilical cord, and related procedures, beliefs, attitudes, values, and opinions of the Italian population regarding the topic, and degree of information and education regarding bone marrow donation. Results: A total of 567 Apulian citizens were enrolled. Of these, 75.3% were female and 96.8% were aged between 18 and 65 years. Most of participants were single (46.9%) and married (47.3%) and had a diploma (44.4%), and less had a degree (35.8%). Significant differences were recorded between gender, singles, and married participants, and participants with a diploma or a degree and the items proposed. Conclusions: A true culture of donation in our region was not clearly spread. Although something has been accomplished in recent years in terms of deceased donor donation, still a great deal needs to be achieved for living donation, which encountered a great deal of resistance. It has been deemed necessary to seek winning solutions to this issue in terms of communication and information campaigns, raising awareness and empowering citizens to express consciously their concerns about organs and tissues and to stand in solidarity with those who suffered.

Purpose: The identification of cardiovascular risk factors in metastatic prostate cancer (PCa) patients prior to the initiation of androgen receptor pathway inhibitors (ARPIs) is important yet challenging. Methods and Results: A nationwide cohort study was conducted utilizing data from the National Health Insurance Research Database containing the Taiwan Cancer Registry. The study population comprised 4739 PCa patients who received abiraterone or enzalutamide between 1 January 2014, and 28 February 2022. The cohort was divided into a training set (n = 3318) and a validation set (n = 1421). Machine learning techniques with random survival forest (RSF) model incorporating 16 variables was developed to predict major adverse cardiovascular events (MACEs). Over a mean follow-up period of 2.1 years, MACEs occurred in 10.9% and 11.3% of the training and validation cohorts, respectively. The RSF model identified five key predictive indicators: age < 65 or ≥75 years, heart failure, stroke, hypertension, and myocardial infarction. The model exhibited robust performance, achieving an area under the curve (AUC) of 85.1% in the training set and demonstrating strong external validity with an AUC of 85.5% in the validation cohort. A positive correlation was observed between the number of risk factors and the incidence of MACEs. Conclusions: This machine learning approach identified five predictors of MACEs in PCa patients receiving ARPIs. These findings highlight the need for comprehensive cardiovascular risk assessment and vigilant monitoring in this patient population. Full article

Background: Genetic insights from diverse populations are key to advancing cancer detection, treatment, and prevention. Unlike other Latin American countries, Colombia lacks a centralized registry for germline and somatic mutations in breast and ovarian cancer. This study describes the country’s first national variant registry, and the occurrence of recurrent mutations and potential founder effects in Colombia. Methods: To address this gap, we implemented the first capturing protocol using the REDCap system. In a group of 213 breast and/or ovarian cancer patients harboring genetic mutations, we collected genetic, clinical, and demographic data from 13 regional centers across Colombia. Statistical analyses assessed variant distribution and patient demographics. Results: Among 229 identified variants (105 germline, 124 somatic), most were classified as pathogenic or likely pathogenic (72.4% germline, 87% somatic). BRCA1 and BRCA2 accounted for the majority of recurrent mutations. Germline recurrent variants (seen >3 times) were recorded for BRCA1 (77.7%; 21/27) and BRCA2 (22.3%; 6/27). Similarly, recurrent somatic variants were identified for BRCA1 (82.6%; 38/46) and BRCA2 (17.4%; 8/46). Notably, four recurrent variants were previously reported as founder mutations: BRCA1 c.1674del (14.3% germline and 23.7% somatic), BRCA1 c.3331_3334del (33.3% germline and 52.6% somatic), BRCA1 c.5123C>A (52.4% germline and 23.7% somatic), and BRCA2 c.2808_2811del (50% germline and 50% somatic). Most cases originated from the Andean region, highlighting regional disparities. Conclusions: This registry offers the first overview of genetic variants in Colombian breast and ovarian cancer patients. Recurrent and region-specific mutations highlight the need for population-focused data to guide targeted screening and personalized care strategies. Full article

Background/Objectives: Out-of-hospital cardiac arrest (OHCA) is associated with high mortality, and outcomes may be influenced by underlying conditions such as cancer, hypertension (HTN), and diabetes mellitus (DM). This study aimed to evaluate whether HTN and DM modify the effects of post-resuscitation treatments—specifically targeted temperature management (TTM) and percutaneous coronary intervention (PCI)—on survival and neurological recovery in OHCA patients with a history of cancer. Methods: This retrospective cohort study analyzed data from the Korean national OHCA registry between January 2018 and December 2021. Adults aged ≥18 years with presumed cardiac-origin OHCA and a documented history of cancer—defined as any prior cancer diagnosis recorded in medical records regardless of remission status—were included. Multivariable logistic regression was used to examine associations between treatment and outcomes, and interaction effects were assessed using adjusted p-values to account for multiple testing. Results: Among the 124,916 EMS-assessed OHCA cases, 4115 patients met the inclusion criteria. TTM and PCI were both statistically associated with good neurological recovery (TTM: adjusted odds ratio [aOR], 1.69; 95% confidence interval [CI], 1.12–2.55; p < 0.05; PCI: aOR, 11.35; 95% CI, 7.98–16.14; p < 0.05). In interaction analyses, the benefit of TTM and PCI for achieving good neurological recovery was attenuated in patients with diabetes mellitus (DM; TTM: aOR, 0.59; 95% CI, 0.23–1.49; PCI: aOR, 4.94; 95% CI, 2.69–9.06) and hypertension (HTN; TTM: aOR, 0.94; 95% CI, 0.49–1.82; PCI: aOR, 7.47; 95% CI, 4.48–12.44), with adjusted p-values < 0.05 for all interactions. Conclusions: In OHCA patients with a history of cancer, TTM and PCI are associated with improved survival and neurological outcomes. However, the presence of comorbidities such as HTN and DM may attenuate these benefits. These findings support the need for individualized post-resuscitation care strategies that account for comorbid conditions. Full article

Background: With a high human immunodeficiency virus (HIV) adult prevalence, people living with HIV (PLHIV) in Botswana continue to experience a high burden of comorbid HIV and cancer. We sought to investigate the trends of acquired immunodeficiency syndrome (AIDS) defining cancers (ADCs), non-AIDS defining cancers (NADCs), and associated risk factors in PLHIV compared with those without HIV. Methods: We analyzed data from adults aged ≥18 years reported in Botswana National Cancer Registry and National Data Warehouse. The crude, age-standardized incidence rate (ASIR), standardized incidence ratios (SIRs) of cancers and time trends were computed. Risk factors were determined using the Cox-regression model. Results: Over a 30-year period, 27,726 cases of cancer were documented. Of these, 13,737 (49.5%) were PLHIV and 3505 (12.6%) were people without HIV and 10,484 (37.8%) had an unknown HIV status. Compared to the HIV-uninfected, the PLHIV had higher and increasing trends in the cancer incidence overall during the study period (from 44.2 to 1047.6 per 100,000; p-trend < 0.001) versus (from 1.4 to 27.2 per 100,000; p-trend < 0.001). The ASIRs also increased in PLHIV for overall ADCs, NADCs and other sub-types like cervical, lung, breast, and conjunctiva cancers (p-trend < 0.001). Further, PLHIV had elevated SIRs for cervical cancer, Kaposi sarcoma in males and some NADCs. The most common risk factors were HIV infection and female sex for ADCs incidence and advanced age and being HIV-uninfected for NADCs incidence. Conclusions: Increasing trends of ADCs and NADCs during ART expansion were observed among PLHIV compared to those without HIV highlighting a greater need for targeted effective prevention and screening strategies including the provision of access to timely HIV and cancer treatment.

Background: Pancreatic cancer (PC) has an extremely poor prognosis and is growing worldwide. In Kazakhstan, it is among the five leading causes of cancer death. However, local epidemiological studies of PC are scarce. A retrospective population-based study was conducted to investigate the PC incidence, mortality, and survival in Kazakhstan, using data from the Electronic Registry of Oncological Patients for the period 2014–2023. Methods: Incidence, prevalence, and crude mortality rates were calculated per 100,000 population. The all-cause mortality rate per 1000 person-years (PY) was obtained based on socio-demographic and medical characteristics and for different regions. Survival analysis was performed using the Kaplan–Meier method and Cox regression models. Results: A total of 11,934 cases were analyzed. The annual incidence rate significantly increased from 5.9 to 6.9 per 100,000. The mortality rate per 100,000 also increased from 4 to 6. The highest incidence was observed in the 60–74 age group (49.2%), with an equal sex distribution. The mortality rate was the highest in patients aged 75 and older. Northern and central regions had the highest incidence rates as of 2023. Atyrau, West Kazakhstan, Pavlodar, and Abay had the highest mortality rates per 1000 PY. The five-year survival rate was 10.9%. An older age, a male sex, advanced cancer stages, and a Russian ethnicity significantly increased the risk of death. Conclusions: PC represents a significant healthcare problem in Kazakhstan, with late diagnosis and poor survival being the main challenges. This study highlights the need to improve the timely detection of PC and address the identified disparities. Full article

Background/Objectives: Over the past few decades, the incidence of melanoma has been steadily rising. In Hungary, the National Institute of Oncology serves as the national center for the diagnosis and treatment of malignancies, including melanoma. This study aims to analyze our patients’ data, providing a comprehensive characterization of melanoma across the country. Methods: We systematically analyzed the clinico-pathological data of melanoma patients treated in the Department of Oncodermatology between 2001 and 2018. Prognostic parameters were collected from the Hospital Information System of the Institute, including gender, age, tumor location, exulceration of primary lesion, Clark level, and Breslow thickness. In addition, survival analysis was also performed. Results: A total of 6267 melanoma patients were included in the study, with a slight predominance of female cases. The most common tumor location was the trunk. Female patients and younger age groups were more likely to present with lower Breslow thickness, while tumors in the head region were associated with increased thickness. Over the study period, the annual median Breslow thickness showed a significant decline. Female gender, younger age, and lower Breslow thickness was correlated with improved overall survival. Over time, the studied patient population exhibited better outcomes. Conclusions: Despite the rising incidence of melanoma in Hungary, the annual median Breslow thickness in our studied patient group showed a decreasing trend, accompanied by improved mortality outcomes. This highlights the critical role of secondary prevention measures and their effectiveness, as well as the impact of novel therapeutic advancements. Full article

Background: Mongolia has a high incidence of hepatocellular carcinoma (HCC), with 85.6 cases per 100,000 population and 70% diagnosed at an advanced stage. HCC accounts for 35% of all cancer-related deaths in the country. The primary treatment for HCC remains hepatotectomy. This study aims to investigate the factors affecting the prognosis of patients undergoing liver resection for HCC in Mongolia. Materials and Methods: A retrospective cohort study was conducted using data from the National Cancer Centre’s eHealth program and cancer registry. The study enrolled 1100 patients who underwent liver resection from 2015 to 2018, with a follow-up period of 5.25–9.25 years to determine survival rates. Results: The study included 980 patients, with a male-to-female ratio of 1.2:1 and an average age of 60 years. Tumour stage II patients had the highest survival rate (46.55%), and those with stage IIIb had the lowest (1.51%) (p = 0.0001). Smaller tumours (≤5 cm) were associated with better survival (p = 0.0006). Histologically, 19.4% had liver cirrhosis, and 80.7% had liver fibrosis. The preoperative median AFP level was 23.9 ng/mL (range 0–121,000 ng/mL). The average survival time post-liver resection was 6.675 years (p = 0.0006). Factors such as blood loss (p = 0.0004), vascular invasion (MaVI-p < 0.0001, MVI p = 0.0011), tumour size ≤ 5 cm (p = 0.0007), and elevated AST and ALT levels significantly influenced long-term survival (p = 0.0004, respectively). Conclusions: The study identified key prognostic factors influencing survival rates in HCC patients post-liver resection. Minimising blood loss, early detection, and managing vascular invasion, along with early-stage detection and treatment, are crucial for improving patient outcomes. Full article

Background and Objectives: Breast reconstruction following mastectomy improves quality of life and psychosocial outcomes, yet it is not consistently performed despite multiple federal mandates. Current data shows decreased reconstruction in minority races, those with a low socioeconomic status, and those holding public health insurance. Many barriers remain misunderstood or unstudied. This study examines barriers to post-mastectomy breast reconstruction to promote a supportive clinical climate by addressing multifactorial obstacles to equitable access to care. Materials and Methods: The California Cancer Registry Data Surveillance, Epidemiology, and End Results (SEER) database and California Health and Human Services Agency Cancer Surgeries Database (2013–2021 and 2000–2021, respectively) were used in this retrospective observational study on mastectomy with immediate breast reconstruction (IBR), delayed breast reconstruction (DBR), or mastectomy only (MO) rates. Data were collected on age, sex, race, insurance type, hospital type, socioeconomic status, and residence. Pearson’s chi-square analysis was performed. Results: We found that 168,494 mastectomy and reconstruction surgeries were performed (82.36% MO, 7% IBR, 10.6% DBR). The 40–49 age group received significantly less MO (38.1%) compared to the 70–74 age group (94.8%, (p = <0.001). Significantly more reconstruction was carried out in patients with private, HMO, or PPO insurance (IBR 75.86%, DBR 75.32%, p = <0.001). Almost all breast surgeries were in urban areas as opposed to rural/isolated rural areas (96.02% vs. 1.55%, p = <0.001). There was no significant difference between races. Of all surgeries, 7.46% were completed in a cancer center with significantly higher rates of IBR. LA County, San Luis Obispo/Ventura County, and Northern CA had significantly more MO than other regions (p = <0.001). Conclusions: Reconstruction rates after mastectomy are low, with only 17.64% of patients undergoing reconstruction. Nationally, 70.5% of patients received MO, with 29.6% undergoing reconstruction. Significant factors positively contributing to reconstruction were private insurance, high SES, cancer center care, and urban residency. Identified barriers include public health insurance enrollment, rural or non-urban residence, older age, low SES, and non-white race/ethnicity, indicating potential monetary influences on care.

Objectives: Patients with cancer often experience severe mental distress, and suicide is an important issue, particularly prevalent in individuals with lung cancer. The present study aimed to investigate the longitudinal incidence of suicide among patients with lung cancer using national registry data. Methods: A population-based retrospective review of patients diagnosed with lung cancer in 2008 was conducted. Longitudinal medical records, including clinical outcomes and medical insurance data, were investigated. The primary outcome was the incidence of suicide, compared between patients undergoing the first curative treatment option (surgery or non-surgery). Cox proportional hazard regression models were used to adjust for medical history, sociodemographic variables, and lifestyle factors. Results: Among the 4495 patients included, 1306 (29.1%) underwent surgery as the first treatment. Compared to the non-surgery group, the surgery group was younger and had a lower Charlon comorbidity score (p < 0.001), higher physical activity (p < 0.001), and higher income level (p < 0.001). The total number of suicides was 28 (0.62%). The surgery group demonstrated similar trends in the development of suicide and early 5-year follow-up to those of the non-surgery group. Conclusions: The longitudinal risk of suicide among patients with lung cancer increased. Both surgical and non-surgical treatment groups demonstrated similar suicide trends, although patients in the surgery group had multiple protective factors. Full article

Background: Assessing cancer survival trends is crucial for monitoring progress in cancer management and prevention. As part of the broader HUN-CANCER EPI study, this analysis examined overall survival (OS) in the Hungarian cancer population between 2011 and 2019. Methods: Using data extracted from the Hungarian National Health Insurance Fund (NHIF) database, short- and long-term OS were estimated for various cancer types according to age, sex, and diagnostic period using Kaplan–Meier analysis. The study also identified cancer types with significant early mortality following diagnosis. Results: From 2011 to 2019, a total of 528,808 patients were diagnosed with cancer. During the 2015–2019 diagnostic period, the lowest 5-year OS rates were observed for esophageal (7.0%), pancreatic (10.7%), liver (12.5%), gallbladder (13.9%), and lung cancer (18.4%). Conversely, tumor types with better OS included testicular cancer (91.6%), thyroid cancer (89.0%), Hodgkin’s lymphoma (84.0%), melanoma (78.6%), and breast cancer (74.1%). A notable proportion of deaths occurred within 2 months of diagnosis for liver (33.2%), pancreatic (27.9%), and gallbladder cancer (29.0%). Significant early mortality within 6 months post-diagnosis was also noted for esophageal (51.3%), stomach (42.9%), and lung cancer (41.7%). Conclusions: The HUN-CANCER EPI study conducted between 2011 and 2019 provides valuable insights into cancer survival patterns in Hungary, emphasizing the importance of early detection and targeted interventions to improve patient outcomes.
