- BACKGROUND: Socioeconomic status (SES) and social support influences cancer survival. If SES and social support affects cancer treatment has not been thoroughly explored. METHODS: A cohort consisting of all patients who were initially diagnosed with or who developed metastatic colorectal cancer (mCRC, n = 781) in three Scandinavian university hospitals from October 2003 to August 2006 was set up. Clinical and socioeconomic data were registered prospectively. RESULTS: Patients living alone more often had synchronous metastases at presentation and were less often treated with combination chemotherapy than those cohabitating (HR 0.19, 95% CI 0.04-0.85, P = 0.03). Surgical removal of metastases was less common in patients living alone (HR 0.29, 95% CI 0.10-0.86, P = 0.02) but more common among university-educated patients (HR 2.22, 95% CI 1.10-4.49, P = 0.02). Smoking, being married and having children did not influence treatment or survival. Median survival was 7.7 months in patients living alone and 11.7 months in patients living with someone (P < 0.001). Living alone remained a prognostic factor for survival after correction for age and comorbidity. CONCLUSION: Patients living alone received less combination chemotherapy and less secondary surgery. Living alone is a strong independent risk factor for poor survival in mCRC.

Prognostic value of baseline functional status measures and geriatric screening in vulnerable older patients with metastatic colorectal cancer receiving palliative chemotherapy : The randomized NORDIC9-study
- 2023

In: Journal of Geriatric Oncology. - : Elsevier. - 1879-4068 .- 1879-4076. ; 14:1

Journal article (peer-reviewed)abstract
- Introduction: Appropriate patient selection based on functional status is crucial when considering older adults for palliative chemotherapy. This pre-planned analysis of the randomized NORDIC9-study explored the prognostic value of four functional status measures regarding progression-free survival (PFS) and overall survival (OS) in vulnerable older patients with metastatic colorectal cancer (mCRC) receiving first-line palliative chemotherapy.Materials and methods: Patients >= 70 years of age with mCRC not candidates for standard full-dose combination chemotherapy were randomized to receive full-dose S1 or reduced-dose S1 + oxaliplatin. At baseline, functional status was assessed using ECOG performance status (ECOG PS), frailty phenotype, Geriatric 8 (G8), and Vulnerable Elderly Survey-13 (VES-13). Multivariable regression models were applied and C-statistics were estimated.Results: In total, 160 patients with a median age of 78 years (IQR: 76-81) were included. While in univariate analyses, ECOG PS, frailty phenotype, and VES-13 were statistically significantly associated with differences in OS between subgroups, G8 was not (HR = 1.55, 95%CI: 0.99-2.41, p = 0.050). In multivariable analyses adjusted for age, sex, body mass index, and treatment allocation, we found significant differences between subgroups for all applied tools and with C-statistics in the moderate range for ECOG PS and VES-13. Concerning PFS, statistically significant differences were observed between subgroups of ECOG PS, G8, and VES-13 both in uni-and multivariable analyses, but not for frailty phenotype.Discussion: In this Nordic cohort of vulnerable older patients with mCRC, baseline ECOG PS, frailty phenotype, G8, and VES-13 showed prognostic value regarding overall survival, and moderate predictive value of models based on ECOG PS and VES-13 was demonstrated.

Quality of Life in Vulnerable Older Patients with Metastatic Colorectal Cancer Receiving Palliative Chemotherapy : The Randomized NORDIC9-Study
- 2021
-
In: Cancers. - : MDPI. - 2072-6694. ; 13:11
-
Journal article (peer-reviewed)abstract
- Quality of life data from randomized trials are lacking in older patients with metastatic colorectal cancer (mCRC). In the randomized NORDIC9-study, reduced-dose S1+oxaliplatin (SOx) showed superior efficacy compared to full-dose S1 monotherapy. We hypothesized that treatment with SOx does not result in inferior quality of life. Patients with mCRC aged ≥70 years and that were not a candidate for standard combination chemotherapy were included and randomly assigned to receive either S1 or SOx. The EORTC QLQ-C30 questionnaire was completed at baseline, after 9, and 18 weeks. The primary endpoint was global Quality of Life (QoL) at 9 weeks. For statistical analysis, a non-inferiority design was chosen applying linear mixed effects models for repeated measurements. The results were interpreted according to statistical significance and anchor-based, clinically relevant between-group minimally important differences (MID). A total of 160 patients aged (median (Interquartile range (IQR))) 78 years (76–81) were included. The QLQ-C30 questionnaire was completed by 150, 100, and 60 patients at baseline, at 9, and 18 weeks, respectively. The difference at 9 weeks in global QoL was 6.85 (95%CI—1.94; 15.65) and 7.37 (0.70; 14.05) in the physical functioning domain in favor of SOx exceeding the threshold for MID. At 18 weeks, the between-group MID in physical functioning was preserved. Dose-reduced combination chemotherapy may be recommended in vulnerable older patients with mCRC, rather than full-dose monotherapy.

The Prognostic Value of Pre-Treatment Circulating Biomarkers of Systemic Inflammation (CRP, dNLR, YKL-40, and IL-6) in Vulnerable Older Patients with Metastatic Colorectal Cancer Receiving Palliative Chemotherapy-The Randomized NORDIC9-Study
- 2022

Journal article (peer-reviewed)abstract
- Appropriate patient selection for palliative chemotherapy is crucial in patients with metastatic colorectal cancer (mCRC). We investigated the prognostic value of C-reactive protein (CRP), derived neutrophil-to-lymphocyte ratio (dNLR), Interleukin (IL)-6, and YKL-40 on progression-free survival (PFS) and overall survival (OS) in the NORDIC9 cohort. The randomized NORDIC9-study included patients >= 70 years with mCRC not candidates for standard full-dose combination chemotherapy. Participants received either full-dose S1 (Teysuno) or a dose-reduced S1 plus oxaliplatin. Blood samples were collected at baseline and biomarkers were dichotomized according to standard cut-offs. Multivariable analyses adjusted for age, sex, ECOG performance status, and treatment allocation; furthermore, C-statistics were estimated. In total, 160 patients with a median age of 78 years (IQR: 76-81) were included between 2015 and 2017. All investigated biomarkers were significantly elevated in patients with either weight loss, >= 3 metastatic sites, or primary tumor in situ. In multivariable analyses, all markers showed significant association with OS; the highest HR was observed for CRP (HR = 3.40, 95%CI: 2.20-5.26, p < 0.001). Regarding PFS, statistically significant differences were found for CRP and IL-6, but not for dNLR and YKL-40. Applying C-statistics, CRP indicated a good prognostic model for OS (AUC = 0.72, 95%CI: 0.67-0.76). CRP is an easily available biomarker, which may support therapeutic decision-making in vulnerable older patients with mCRC.

Metastatic colorectal carcinomas with high SATB2 expression are associated with better prognosis and response to chemotherapy : a population-based Scandinavian study
- 2020
-
In: Acta Oncologica. - : Taylor & Francis. - 0284-186X .- 1651-226X. ; 59:3, s. 284-290
-
Journal article (peer-reviewed)abstract
- Background: Survival and response to therapy in patients with metastatic colorectal cancer (mCRC) are very heterogeneous. There is an unmet need for better markers of prognosis and treatment benefit for mCRC patients. The homeobox 2 gene SATB2 has a highly specific expression in colorectal tissue and is associated with better prognosis in non-metastatic CRC.Material and methods: A population-based cohort of 798 mCRC patients was analysed. From primary tumour material, protein expression was assessed by immunohistochemistry. BRAF and KRAS mutation status was also determined. Associations with clinicopathological data, overall and progression-free survival and response to first-line chemotherapy were analysed.Results: Tumour tissue and clinical data were available from 467 patients. SATB2 was strongly expressed in 58% of cases, significantly more in left-sided, low-grade and wild-type BRAF tumours. Patients with high SATB2 tumours had longer overall survival compared with low SATB2 tumours (median 13 vs 8 months respectively, p < .001). Chemotherapy was given to 282 patients (63%). Patients with high SATB2 tumours had longer OS (median 22 vs 15 months respectively, p = .001) and more often responded to chemotherapy than those with low SATB2 (objective response 43% vs 29%, p = .02; clinical response 83% vs 67%, p = .004). Progression-free survival on first-line irinotecan chemotherapy was longer in high SATB2 cases (median 8 vs 4 months respectively, p = .019). Patients with both low SATB2 expression and mutated BRAF (n = 69) had particularly poor survival compared to the rest (median 8 and 12 months respectively, p = .001). In multivariable analysis, the SATB2 findings were independent of known clinicopathological prognostic markers, including BRAF mutation status.Conclusion: Patients with mCRC expressing high level of SATB2 have better prognosis and response to chemotherapy than those with low SATB2 expression. Patients with both low SATB2 expression and mutated BRAF had particularly poor prognosis and could thus benefit from more aggressive therapies.

Survival-associated heterogeneity of marker-defined perivascular cells in colorectal cancer
- 2016
-
In: Oncotarget. - : Impact Journals, LLC. - 1949-2553. ; 7:27, s. 41948-41958
-
Journal article (peer-reviewed)abstract
- Perivascular cells (PC) were recently implied as regulators of metastasis and immune cell activity. Perivascular heterogeneity in clinical samples, and associations with other tumor features and outcome, remain largely unknown.Here we report a novel method for digital quantitative analyses of vessel characteristics and PC, which was applied to two collections of human metastatic colorectal cancer (mCRC).Initial analyses identified marker-defined subsets of PC, including cells expressing PDGFR-β or α-SMA or both markers. PC subsets were largely independently expressed in a manner unrelated to vessel density and size. Association studies implied specific oncogenic mutations in malignant cells as determinants of PC status. Semi-quantitative and digital-image-analyses-based scoring of the NORDIC-VII cohort identified significant associations between low expression of perivascular PDGFR-α and -β and shorter overall survival. Analyses of the SPCRC cohort confirmed these findings. Perivascular PDGFR-α and -β remained independent factors for survival in multivariate analyses.Overall, our study identified host vasculature and oncogenic status as determinants of tumor perivascular features. Perivascular PDGFR-α and -β were identified as novel independent markers predicting survival in mCRC. The novel methodology should be suitable for similar analyses in other tumor collections.

Maintenance Therapy With Cetuximab Every Second Week in the First-Line Treatment of Metastatic Colorectal Cancer : The NORDIC-7.5 Study by the Nordic Colorectal Cancer Biomodulation Group
- 2015
-
In: Clinical colorectal cancer. - : Elsevier BV. - 1533-0028 .- 1938-0674. ; 14:3, s. 170-176
-
Journal article (peer-reviewed)abstract
- In the NORDIC-7.5 trial, cetuximab administered every 2 weeks in 152 patients with Kirsten rat sarcoma viral oncogene homolog wild type metastatic colorectal cancer was investigated. After 4 months of induction therapy with Nordic FLOX (oxaliplatin, bolus 5-fluorouracil, and bolus folinic acid) and cetuximab, patients continued with cetuximab monotherapy. Cetuximab might have added to a longer chemotherapy-free interval, but needs to be validated in clinical trials. Background: In the NORDIC-7.5 trial, how cetuximab might safely and conveniently be added to an intermittent treatment strategy in patients with prospectively selected Kirsten rat sarcoma viral oncogene homolog wild type (KRASwt) metastatic colorectal cancer (mCRC) was investigated. Patients were treated in a multicenter phase II trial with cetuximab in combination with the Nordic bolus FLOX (oxaliplatin, 5-fluorouracil, and folinic acid) for 4 months followed by maintenance cetuximab. Patients and Methods: Patients had KRASwt, nonresectable mCRC, no previous chemotherapy, and Eastern Cooperative Group performance status of 0 to 2. Patients received 8 courses of Nordic FLOX (oxaliplatin 85 mg/m(2) over 1 hour on day 1, and 5-fluorouracil 500 mg/m(2) as a bolus injection, followed 30 minutes later with bolus folinic acid 60 mg/m(2) on days 1 and 2). Cetuximab was administered every 2 weeks at a dose of 500 mg/m(2) for 16 weeks followed by cetuximab as maintenance therapy until disease progression. Results: Between July 2008 and September 2010, 152 KRASwt patients were included. The response rate was 62% (95% confidence interval [CI], 54%-69%), median progression-free survival was 8.0 months (95% CI, 7.5-8.9) and median overall survival was 23.2 (95% CI, 18.1-27.4) months. Twenty-one patients (14%) had later R0-resection of metastasis. FLOX with cetuximab was reintroduced in 47 of 85 patients (55%). The most common Grade 3/4 nonhematologic adverse events were diarrhea in 14 patients (9%), skin rash in 13 patients (9%), infection without neutropenia in 11 patients (7%), and fatigue in 11 patients (7%). Conclusion: In a prospectively selected KRASwt population, biweekly cetuximab was safely integrated in an intermittent chemotherapy strategy and might have added to a longer chemotherapy-free interval. However, the combination of biweekly cetuximab with chemotherapy needs to be validated in trials using FOLFOX (oxaliplatin, fluorouracil, and leucovorin) or FOLFIRI (irinotecan, fluorouracil, and leucovorin).

A randomized study comparing short-time infusion of oxaliplatin in combination with capecitabine XELOX(30) and chronomodulated XELOX(30) as first-line therapy in patients with advanced colorectal cancer
- 2010
-
In: Annals of Oncology. - : Elsevier BV. - 0923-7534 .- 1569-8041. ; 21:1, s. 87-91
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Chronotherapy is one of the several approaches to increase efficacy and reduce toxicity of chemotherapy. In a phase II study in the second-line in patients with metastatic colorectal cancer (mCRC), we found that chronomodulated XELOX (XELOX(30Chron)) was a well-tolerated regimen with potentially reduced toxicity. PATIENTS AND METHODS: One hundred and forty-one patients with unresectable mCRC were enrolled in a randomized study comparing standard XELOX (XELOX(30)), arm A, and XELOX(30Chron), arm B-both with short-time infusion of oxaliplatin-with the primary aim of reducing overall toxicity. RESULTS: Overall toxicity grade 2-4 was 90% versus 85%, P = 0.47 and grade 3-4 was 31% versus 37%, P = 0.6 in arm A and B, respectively. We found no significant differences in median overall survival (17.6 versus 15.5 months; P = 0.068) and median progression-free survival (8.9 versus 8.8 months; P = 0.7). The incidence of grade 3 neuropathy was 16% in arm A and 19% in arm B (P = 0.7) after a cumulative dose of oxaliplatin of 1000 mg/m(2). CONCLUSION: XELOX(30Chron) does not reduce toxicity or improve efficacy. A 30-min infusion of oxaliplatin is safe and does not increase the severity of chronic neuropathy.
