Background and purpose: In the late 1990s, the Nordic countries, with Norway at the top, were among the countries with the highest prostate cancer mortality in the world. We present updated mortality rates from the Nordic countries and discuss possible interpretations of changes in trends.

Material and methods: Age-standardized rates for prostate-specific mortality in 1985-2022, estimated lifetime risk of death (0-84 years) and annual changes in mortality were obtained from the NORDCAN database. Joinpoint regression was used to evaluate trend changes for the period 1985-2022. For comparison, rates from other European countries from 2022 were retrieved from the GLOBOCAN database.

Results: Between 1995-99 and 2018-22, mortality in men aged 40-84 years decreased from 38% in Denmark to 59% in Norway. By 2022 Norway had the second lowest mortality among the Nordic countries overall, and the lowest under 85 years. The life-time risk of dying from prostate cancer declined from 5.6-7.1% in 1995-99 to 3.1-4.2% in the last 5-year period. During the last years mortality has decreased most rapidly in Sweden (4.5% annually from 2016) and Norway (4.3% annually from 2014). The Nordic countries are no longer among the countries with the highest mortality in Europe.

Interpretation: Mortality from prostate cancer has decreased significantly in the Nordic countries over the last decades. Possible explanatory factors are likely to include improvements in prostate cancer management strategies and treatment.

Introduction: Organ preservation (OP) strategies are gaining interest in improving the quality of life in the management of rectal cancer, particularly for tumors located in the distal or middle rectum. The optimal OP protocol is still not standardized and relies on randomized trials. This review summarizes past and ongoing studies on OP protocols for adenocarcinoma of the distal and middle rectum.

Method: We searched for articles and abstracts on randomized clinical trials investigating OP approaches for rectal cancer, including data presented at the LUCARRE Congress held in Nice on November 25, 2023, covering ongoing and recently published trials on rectal preservation.

Results: Our review's findings are presented in four tables: the first evaluates key trials with overall survival (OS) as the primary endpoint; the second provides an overview of past Phase III trials; the third reviews Phase II/III trials that specifically focus on local excisions (LE); and finally, the fourth summarizes ongoing trials. Each table is accompanied by detailed comments elucidating the significance and implications of the presented data, alongside a review of current guidelines.

Interpretation: We highlight the growing interest in OP strategies for rectal cancer management to enhance patients' quality of life. Despite the lack of international consensus on the optimal OP protocol, past and ongoing randomized trials provide valuable findings into the evolving management strategies of rectal cancer treatment. The presented data supports the role of randomized phase III trials to provide evidence for a change in clinical practice.

Introduction: To target psychological support to cancer patients most in need of support, screening for psychological distress has been advocated and, in some settings, also implemented. Still, no prior studies have examined the appropriate 'dosage' and whether screening for distress before cancer treatment may be sufficient or if further screenings during treatment are necessary. We examined the development in symptom trajectories for breast cancer patients with low distress before surgery and explored potential risk factors for developing burdensome symptoms at a later point in time.

Methods: In total, 299 patients newly diagnosed with breast cancer who scored < 7 on the distress thermometer were included between August 2017 and October 2019 at the Department of Breast Surgery, Rigshospitalet, Copenhagen. Patients were followed through electronic questionnaires at baseline before surgery and after 6, 12, and 18 months. We used latent class mixed models to identify sub-groups of patients with similar development in distress, anxiety, depression, breast cancer-specific health-related quality of life, self-efficacy, and fear of recurrence over time. Logistic and multinomial regression analyses were applied to examine clinical and sociodemographic factors associated with specific symptom trajectories.

Results: We did not identify any sub-groups of women with low distress at diagnosis who developed disabling psychological symptoms up to 18 months after diagnosis. However, we did identify a sub-group of 52% of the women who experienced persistent mild anxiety (Generalised Anxiety Disorder [GAD]-7 score 5-9). Adjusted for baseline treatment modalities and sociodemographic characteristics, women having low social support (odds ratio [OR]: 2.90; 95% confidence interval [CI]: 1.07-7.87) or living with a partner (OR: 3.18; 95% CI: 1.38-7.34) were more likely to experience persistent mild anxiety.

Interpretation: The results show that the majority of women with low distress at breast cancer diagnosis do not experience an increase in psychological symptoms over time. Screening for distress at cancer diagnosis may be an essential step to identify most breast cancer patients in need of professional support for psychological symptoms.

Background and purpose: Comprehensive data on factors affecting partnership satisfaction among adolescents and young adult (AYA) cancer survivors are limited. Our study examines partnership satisfaction, sexual satisfaction, and attachment insecurities, exploring how attachment-related anxiety and avoidance influence the relationship between sexual and partnership satisfaction across major tumor entities in this population.

Patients and methods: We utilized data from two measurement time points (t1 and t6) of the AYA-LE study, a prospective longitudinal investigation examining the temporal course and associated factors of life satisfaction and psychological distress among AYA cancer survivors. We examined the mediating effect of attachment insecurities (ECR-RD) on the relationship between sexual satisfaction (FLZ-Sex) and partnership satisfaction (PFB), while controlling for sociodemographic and clinical characteristics, in a sample of N = 275 participants.

Results: Higher sexual satisfaction was correlated with lower attachment-related anxiety (r = -0.51, p < 0.001) and lower attachment-related avoidance (r = -0.49, p < 0.001). Both lower attachment-related anxiety and attachment-related avoidance were correlated with higher partnership satisfaction (r = -0.64, p < 0.001 and r = -0.72, p < 0.001, respectively). Sexual satisfaction partially predicted partnership satisfaction of AYA cancer survivors through attachment-related anxiety and attachment-related avoidance while the mediating effect accounted for 75% of the total effect.

Interpretation: The associations between sexual satisfaction, partnership satisfaction, and attachment highlight the need to address emotional and relational aspects in supportive care for AYA cancer survivors. There is a clear need for more targeted studies on attachment patterns, sexual satisfaction, and partnership satisfaction in this specific population to further refine and validate these approaches.

Background and purpose: Lymphedema is a debilitating late effect of cancer treatments, yet its prevalence beyond breast cancer remains understudied. This study examined the prevalence of lymphedema symptoms across cancer diagnoses and their association with depression, pain interference, and health-related quality of life (HRQoL).

Patients/material and methods: This cross-sectional study was conducted at the Department of Oncology, Copenhagen University Hospital, from February to April 2021, as part of a broader investigation into cancer-related late effects. Here, we present data from patients in follow-up who received online lymphedema symptom assesments (swelling, heaviness, or tightness). Utilized questionnaires were the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, the Major Depression Inventory, and the Brief Pain Inventory. Associations between lymphedema symptoms and depression, pain interference, and HRQoL were examined via multiple linear regression.

Results: Of 1,901 patients in follow-up who received the lymphedema symptom items, 1,296 responded. Most participants had breast cancer (48%), followed by testicular (17%), gynecological (16%), and head/neck cancer (11%). One-third (n = 397) reported lymphedema symptoms, with 38% (n = 152) reporting moderate/severe symptoms. The highest symptom prevalence was seen in gynecological cancer (59%), followed by head/neck (41%), breast (21%), and testicular cancer (19%). Participants with moderate/severe lymphedema symptoms were significantly more likely to report higher depression and pain interference scores and lower HRQoL scores compared to those with no/mild symptoms.

Interpretation: Lymphedema symptoms are highly prevalent among patients who have completed treatment for diverse cancers and associated with higher scores for depression and pain interference, and lower HRQoL.

Background and purpose: To present the clinical outcomes of two series of patients treated with carbon-ion radiotherapy (CIRT) and definitive photon radiotherapy (RT) for adenoid cystic carcinoma of the head and neck (HN-ACC).

Material and methods: The first cohort of six patients was referred from Oslo University Hospital (OUS) to Centro Nazionale di Adroterapia Oncologica (CNAO, Pavia, Italy) for CIRT in 2014-2017. The second cohort included 18 patients treated with definitive photon RT at OUS in 2005-2017. The primary endpoint was an evaluation of osteoradionecrosis (ORN) in the two cohorts. The secondary endpoints were treatment efficacy by local control (LC), progression-free survival (PFS), and overall survival (OS).

Results: The tumor stage was T4 for all the patients in the CIRT group and 15 (84%) in the photon group. There were three (50%) patients with grade 3 ORN in the CIRT group compared to one (6%) with grade 3 ORN in the photon group (p = 0.05). The 5-year LC (95% CI), PFS, and OS rates in the CIRT group and the photon group were 33% (11-100) and 39% (19-76), 17% (9-100) and 23% (2-59), and 80% (52-100) and 50% (31-82), respectively.

Interpretation: Half of the patients in the CIRT cohort experienced ORN requiring surgical management during the follow-up. Patients with ACC referred for CIRT often have a worse prognosis and more advanced disease than patients treated with photons. When returning from the referring center, these patients need close follow-up often in collaboration with treating centers to manage toxicity that impacts quality of life.

Objective: This study aims to assess the long-term safety and efficacy of adding pazopanib to neo-adjuvant radiotherapy followed by surgery in patients with high-risk non-metastatic soft tissue sarcoma of the trunk and extremities treated in the PASART-1 and PASART-2 trials, as well as to compare the PASART cohorts to a control cohort receiving standard treatment during the same time period from the Netherlands Cancer Registry (IKNL) to investigate if adding pazopanib improves Overall Survival (OS).

Methods: Updated follow-up data on disease control, survival and long-term toxicities of the PASART-trials were extracted from electronic patient records. The effect of adding pazopanib to neo-adjuvant radiotherapy on OS was investigated by comparing the combined PASART cohorts to the IKNL cohort via direct comparison and exact matching analysis.

Results: PASART-trials included 34 patients, IKNL cohort included 487 patients. After a median follow-up of 75.4 months (range: 30-131 months) the 1-year, 2-year and 5-year OS in the PASART-trials were 97% (95% confidence interval [CI]: 91.5-100), 85.3% (95% CI: 74.2-98.1), 79.3% (95% CI: 66.8-94.2), respectively. Matching resulted in 23 PASART and 89 IKNL patients. Adding pazopanib did not significantly improve OS when compared to standard treatment (IKNL) in a direct comparison (hazard ratio [HR]: 0.58; 95% CI: 0.30-1.13) or matched analysis (HR: 0.70; 95% CI: 0.29-1.73). Long-term toxicities, mainly fibrosis (n = 6) and edema (n = 2), were observed in 11 PASART patients and comparable to historical controls.

Interpretation: The addition of pazopanib had tolerable long-term toxicity but did not improve OS when compared to a control cohort receiving standard treatment.

Background and purpose: We report the incidence, characteristics, and comorbidities of the complete unselected Danish cohort of patients with thymic epitheliums (TETs), which may serve as evidence for guiding treatment, surveillance, and counselling of TET patients.

Patients and methods: All patients diagnosed with TETs from January 1st, 2015, to December 31st, 2020, were identified using the Danish Pathology Data Registry. Data on patient characteristics, comorbidities, and tumor histology were collected from electronic medical records available for all patients.

Results: The cohort consisted of 283 patients with a mean age of 64 years (SD: 12). The crude rate was 8.2/1,000,000 TETs annually, thus higher than the age-standardized rates of 4.8/1,000,000 in the WHO World Standard Population and 6.1/1,000,000 in the European Standard Population. Thymomas were diagnosed in 240 patients (85%) (9% type A, 31% AB, 18% B1, 26% B2, 6% B3, 5% micronodular, 0.4% metaplastic, and 5% of unspecified subtype), thymic carcinomas in 39 patients (14%), and thymic neuroendocrine tumors in 4 patients (1.4%). Tumors in Tumour, Node, Metastasis (TNM) stage I were diagnosed in 181 patients (64%) and were mostly thymomas (72%). Prior to TET diagnosis, 91 (32%) patients presented with autoimmune disorders (19% myasthenia gravis) and 82 patients (29%) had at least one cancer diagnosis.

Interpretation: We found a higher incidence of TETs in Denmark than in previous European population-based studies, while reporting a similar distribution of histological types and tumor stages. Furthermore, we found an increased prevalence of autoimmune disorders and cancers in the cohort before TET diagnosis compared to the general population.

Background and purpose: The prevalence of sequelae following rectal cancer (RC) treatment is high. We investigate the prevalence and temporal change in sexual dysfunction among male RC patient, along with their counselling and treatment needs and associations between sexual dysfunction and clinical factors. Patient/materials and methods: Patient-reported outcome measures were completed 3 and 12 months after RC surgery. We used the five-item International Index of Erectile Function score to measure sexual function in sexually active patients and ad hoc items to explore their sexual activity level, causes of disrupted sexual life, and self-rated sexual function. Clinical data were obtained from the Danish Colorectal Cancer Group database Results: In total, 364 of 490 (74%) eligible male patients were included. Their mean age (standard deviation [SD]) at surgery was 68.3 (11) years. Forty-one percent reported being sexually inactive at the time of diagnosis. Among sexually active men, 44% had resigned from sexual activity at 12 months, mainly due to erectile dysfunction (ED), as reported by 55%. Only 16% experienced improvement; 19% experienced a worsening of their ED category in the 12-month observation time. Stoma was associated with both ED (odds ratio [OR] 5.6; 95% confidence interval [CI] [1.8, 17.4]) and low self-rated sexual function (OR 3.5 95% CI [1.8 , 6.7]). Phone contact to discuss sexual problems was requested by 29%; 19% were referred to professional treatment.

Interpretation: Sexual dysfunction is common following RC, without improvement over time. Systematic screening enables identification of patients needing professional help.

Background and purpose: We previously demonstrated positive effects on quality of life and mental health following breast cancer when comparing a nurse-led follow-up program without scheduled visits (MyHealth) to regular follow-up. This study aims to examine whether MyHealth also positively impacts self-reported work ability.

Patients/material and methods: A total of 288 patients, potentially active on the labour market, were randomized to MyHealth or control follow-up after primary treatment for early-stage breast cancer (2017-2019). MyHealth included individual self-management sessions, electronic symptom monitoring, and assistance with navigating healthcare services. Control follow-up consisted of biannual outpatient visits with a physician. Linear mixed-effect models were applied to evaluate the effect of MyHealth on self-reported work ability at 6, 12, 24, and 36 months after randomization as measured by the Work Ability Score (WAS).

Results: Work ability increased significantly in both groups during the first 6 months (mean WAS increase MyHealth: 1.64, 95% confidence interval [CI]: 1.26; 2.02 and control: 1.57, 95% CI: 1.17; 1.97) and continued to increase slightly but non-significantly (p-values > 0.13) until end of follow-up at 36 months. Improvement was especially pronounced among patients reporting poor work ability at baseline. Differences in mean WAS between patients in MyHealth and control follow-up were non-significant and close to zero at all time points (-0.21 to 0.48).

Interpretation: The MyHealth follow-up program had no additional effect on self-reported work ability compared to regular follow-up. Future interventions should target patients with poor work ability and include components specifically designed to enhance work ability.
