Characteristics and fate of patients with rectal cancer not entering a curative-intent treatment pathway: A complete nationwide registry cohort of 3,304 patients

Background: Treatment options for advanced and metastatic rectal cancer have increased during the past decades. However, a considerable proportion of the patients are not eligible for curative treatment, and data on this subset are scarce from a population-based perspective. This study aimed to describe treatment pathways and survival in a national cohort of patients with primary stage IV rectal cancer or stage I-III rectal cancer not eligible for curative treatment. Methods: A national cohort of all patients reported 2008–2015 to the Norwegian Colorectal Cancer Registry with primary metastatic rectal cancer or who did not undergo curative resections for stage I-III rectal cancer was studied with regard to patient characteristics, treatments, and survival. Results: Of 8291 patients diagnosed with rectal cancer, 3304 (39.9%) were eligible for analysis. The majority (76.8%) had metastatic disease, and 23.2% did not undergo curative resections for other reasons. We identified four main treatment journeys: no tumour-directed treatment, 25.1%; resection of the primary tumour, 44.6%; oncological treatment, 28.4%; and R0 resection of the primary tumour and metastases, 1.9%; these translated into ten different treatment pathways. Survival differed considerably between a median of 5.3 months for M1 disease with non-tumour-directed treatment to a five-year survival of 67% for M1 with R0 resection. Conclusion: Almost 40% of all patients with rectal cancer did not enter a curative-intent treatment pathway. The patient journeys and outcomes varied greatly. This large but understudied population warrants further in-depth analyses of treatment efficacy and effects on quality of life.publishedVersio

Exploring variables affecting sense of coherence and social support in recovery after colorectal cancer surgery among the oldest old

Objective To explore the associations between sense of coherence, perceived social support, and demographic and clinical characteristics among survivors ≥80 years treated for curable colorectal cancer. Methods This exploratory, cross-sectional survey investigates 56 individuals surgically treated for stage I-III colorectal cancer between one and five years prior. Statistical analysis permitted exploration of associations between sense of coherence, perceived social support, and demographic- and clinical variables. Results Lower sense of coherence was associated with higher age, limitations in physical function, and the need for homecare nursing. Lower perceived social support was associated with re-admission, higher age at time of surgery, and male gender. No correlations were found between sense of coherence and perceived social support. Conclusion The results are important for healthcare professionals to consider when dealing with older people who underwent surgery for colorectal cancer, especially in the discharge process to facilitate optimal follow-up care and recovery.publishedVersio

Experiences of recovery from colorectal cancer surgery after hospital discharge among the oldest old: a qualitative study

Colorectal cancer affects a large number of people aged ≥80 years. Little is known about how they manage after discharge from hospital. The aim of this study was to explore the experiences of individuals aged ≥80 years recovering from surgery for colorectal cancer, and the challenges they may encounter after discharge from hospital. Data were collected between January and March 2016 through in-depth interviews with ten participants approximately one month after surgery. Inductive thematic analysis was employed to analyse the data. The COREQ checklist was used in reporting this study. Two themes were identified: Managing the recovery from CRC surgery, and Insufficient follow-up from the healthcare services after CRC surgery. The findings indicate that older people treated for colorectal cancer manage surprisingly well after discharge despite challenges in their recovery; however, there are seemingly areas of improvement in their follow-up healthcare.publishedVersio

Long-term recovery after colorectal cancer surgery among the old: a qualitative study

Background Colorectal cancer is the third most frequently diagnosed cancer worldwide, disproportionally affecting older people. With modern treatment, older people are surviving cancer treatment and recovery. However, only a limited number of studies on the older person’s experience of recovery exist. Knowledge of the experience of recovery among people 80 years or older is essential to optimize recovery and follow-up care. Objective The aim of this study was to explore the experiences of persons 80 years or older during recovery up to 2 years after curative colorectal cancer surgery. Methods This exploratory inductive qualitative study was conducted through 18 individual in-depth interviews between July 2020 and June 2021. Content analysis was used to analyze the data. Results The main theme identified was Recovery among the old is a complex process. It indicated that older people operated on for colorectal cancer may have intricate health challenges that affect recovery in addition to their cancer and treatment. The main theme is built upon the subthemes Individual factors affect colorectal cancer recovery and External support systems facilitate and impede colorectal recovery. Conclusion Important resources for recovery among old patients included their own coping ability and support from social networks and healthcare services. The identified barriers to recovery included other health problems and issues with healthcare services delivery. Implications for Practice It is essential for healthcare personnel in contact with older patients to be aware of factors that influence their recovery to identify and preserve the older person’s resources and implement health-promoting initiatives to optimize recovery when needed.publishedVersio

Organizational structures influencing timely recognition and acknowledgment of end-of-life in hospitals – A qualitative study of nurses' and doctors’ experiences

Healthcare personnel's timely recognition and acknowledgment of end-of-life (EOL) is fundamental for reducing futile treatment, enabling informed decisions regarding the last days or weeks of life, and focusing on high-quality palliative care. The aim of this study is to explore and describe nurses' and doctors' experiences of how organizational structures in hospitals influence timely recognition and acknowledgment of EOL. A qualitative explorative design was applied, with data collected through 12 individual in-depth interviews using a semi-structured interview guide. A total of 6 nurses and 6 doctors were strategically recruited from medical and surgical wards in a Norwegian hospital. Qualitative content analysis was used. The analysis revealed the theme The importance of hospital organizational structures in timely recognition and acknowledgment of EOL and a subtheme comprising three areas of organizational structures influencing timely recognition and acknowledgment of EOL; Challenges to and demands of continuity, collaboration, and time. The study's results show challenges in identifying when cancer patients approach the last weeks and days of life within hospital wards. For nurses and doctors to be able to recognize and acknowledge EOL, continuity of care, collaboration, and time is needed. A fragmented healthcare system, with a predominant focus on treatment and cure, may prevent cancer patients from receiving timely palliative, care causing unnecessary suffering.publishedVersio

Accurate population-based model for individual prediction of colon cancer recurrence

Background Prediction models are useful tools in the clinical management of colon cancer patients, particularly when estimating the recurrence rate and, thus, the need for adjuvant treatment. However, the most used models (MSKCC, ACCENT) are based on several decades-old patient series from clinical trials, likely overestimating the current risk of recurrence, especially in low-risk groups, as outcomes have improved over time. The aim was to develop and validate an updated model for the prediction of recurrence within 5 years after surgery using routinely collected clinicopathologic variables. Material and methods A population-based cohort from the Swedish Colorectal Cancer Registry of 16,134 stage I–III colon cancer cases was used. A multivariable model was constructed using Cox proportional hazards regression. Three-quarters of the cases were used for model development and one quarter for internal validation. External validation was performed using 12,769 stage II–III patients from the Norwegian Colorectal Cancer Registry. The model was compared to previous nomograms. Results The nomogram consisted of eight variables: sex, sidedness, pT-substages, number of positive and found lymph nodes, emergency surgery, lymphovascular and perineural invasion. The area under the curve (AUC) was 0.78 in the model, 0.76 in internal validation, and 0.70 in external validation. The model calibrated well, especially in low-risk patients, and performed better than existing nomograms in the Swedish registry data. The new nomogram’s AUC was equal to that of the MSKCC but the calibration was better. Conclusion The nomogram based on recently operated patients from a population registry predicts recurrence risk more accurately than previous nomograms. It performs best in the low-risk groups where the risk-benefit ratio of adjuvant treatment is debatable and the need for an accurate prediction model is the largest.publishedVersio

Influence of microsatellite instability and KRAS and BRAF mutations on lymph node harvest in stage I–III colon cancers

Lymph node (LN) harvest is influenced by several factors, including tumor genetics. Microsatellite instability (MSI) is associated with improved node harvest, but the association to other genetic factors is largely unknown. Research methods included a prospective series of stage I–III colon cancer patients undergoing ex vivo sentinel-node sampling. The presence of MSI, KRAS mutations in codons 12 and 13, and BRAF V600E mutations was analyzed. Uni- and multivariate regression models for node sampling were adjusted for clinical, pathological and molecular features. Of 204 patients, 67% had an adequate harvest (≥12 nodes). Adequate harvest was highest in patients whose tumors exhibited MSI (79%; odds ratio [OR] 2.5, 95% confidence interval [CI] 1.2–4.9; P = 0.007) or were located in the proximal colon (73%; 2.8, 1.5–5.3; P = 0.002). In multiple linear regression, MSI was a significant predictor of the total LN count (P = 0.02). Total node count was highest for cancers with MSI and no KRAS/BRAF mutations. The independent association between MSI and a high LN count persisted for stage I and II cancers (P = 0.04). Tumor location in the proximal colon was the only significant predictor of an adequate LN harvest (adjusted OR 2.4, 95% CI 1.2–4.9; P = 0.01). An increase in the total number of nodes harvested was not associated with an increase in nodal metastasis. In conclusion, number of nodes harvested is highest for cancers of the proximal colon and with MSI. The nodal harvest associated with MSI is influenced by BRAF and KRAS genotypes, even for cancers of proximal location. Mechanisms behind the molecular diversity and node yield should be further explored.publishedVersio

Assessing the association of oxytocin augmentation with obstetric anal sphincter injury in nulliparous women: A population-based, case-control study

Objective To assess the association of oxytocin augmentation with obstetric anal sphincter injury among nulliparous women. Design Population-based, case–control study. Setting Primary and secondary teaching hospital serving a Norwegian region. Population 15 476 nulliparous women with spontaneous start of labour, single cephalic presentation and gestation ≥37 weeks delivering vaginally between 1999 and 2012. Methods Based on the presence or absence of oxytocin augmentation, episiotomy, operative vaginal delivery and birth weight (<4000 vs ≥4000 g), we modelled in logistic regression the best fit for prediction of anal sphincter injury. Within the modified model of main exposures, we tested for possible confounding, and interactions between maternal age, ethnicity, occiput posterior position and epidural analgaesia. Main outcome measure Obstetric anal sphincter injury. Results Oxytocin augmentation was associated with a higher OR of obstetric anal sphincter injuries in women giving spontaneous birth to infants weighing <4000 g (OR 1.8; 95% CI 1.5 to 2.2). Episiotomy was not associated with sphincter injuries in spontaneous births, but with a lower OR in operative vaginal deliveries. Spontaneous delivery of infants weighing ≥4000 g was associated with a threefold higher OR, and epidural analgaesia was associated with a 30% lower OR in comparison to no epidural analgaesia. Conclusions Oxytocin augmentation was associated with a higher OR of obstetric anal sphincter injuries during spontaneous deliveries of normal-size infants. We observed a considerable effect modification between the most important factors predicting anal sphincter injuries in the active second stage of labour

Lower conversion rate with robotic assisted rectal resections compared with conventional laparoscopy; a national cohort study

Background Conversion from laparoscopic to open access colorectal surgery is associated with a poorer postoperative outcome. The aim of this study was to assess conversion rates and outcomes after standard laparoscopic rectal resection (LR) and robotic laparoscopic rectal resection (RR). Methods A national 5-year cohort study utilizing prospectively recorded data on patients who underwent elective major laparoscopic resection for rectal cancer. Data were retrieved from the Norwegian Registry for Gastrointestinal Surgery and from the Norwegian Colorectal Cancer Registry. Primary end point was conversion rate. Secondary end points were postoperative complications within 30 days and histopathological results. Chi-square test, two-sided T test, and Mann–Whitney U test were used for univariable analyses. Both univariable and multivariable logistic regression analyses were used to analyze the relations between different predictors and outcomes, and propensity score matching was performed to address potential treatment assignment bias. Results A total of 1284 patients were included, of whom 375 underwent RR and 909 LR. Conversion rate was 8 out of 375 (2.1%) for RR compared with 87 out of 909 (9.6%) for LR (p  30. Conversion was associated with higher rates of major complications (20 out of 95 (21.2%) vs 135 out of 1189 (11.4%) p = 0.005), reoperations (13 out of 95 (13.7%) vs 93 out of 1189 (7.1%) p = 0.020), and longer hospital stay (median 8 days vs 6 days, p = 0.001). Conclusion Conversion rate was lower with robotic assisted rectal resections compared with conventional laparoscopy. Conversions were associated with higher rates of postoperative complications.publishedVersio
