- 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.

- LBA3503Background: Locally advanced colon cancer presents a therapeutic challenge regarding improving survival and minimizing side effects by optimizing the timing of surgical and systemic treatments. Neoadjuvant chemotherapy is a widely accepted approach in numerous cancers as it aims to eliminate micrometastases and reduce tumor size. Our study aimed to assess the impact of neoadjuvant chemotherapy on locally advanced colon cancer compared to standard initial surgery. Methods: This was a randomized, controlled, phase III clinical trial. Patients aged 18 years or older with biopsy-proven colon cancer were eligible for inclusion if staged as T4 or T3 with invasion depth >= 5 mm, N0-2, and M0 according to CT scan evaluation. Patients were randomly assigned to either standard upfront surgery or surgery after neoadjuvant chemotherapy with either 3 cycles of CAPOX (oxaliplatin, capecitabine every 3 weeks) or 4 cycles of FOLFOX (oxaliplatin, 5FU every 2 weeks). Adjuvant chemotherapy was chosen based on the pathological stage of the cancer according to guidelines. The primary endpoint, disease-free survival (DFS), was analyzed on an intent-to-treat basis. The sample size was set at 125 patients per arm, based on a projected increase in two-year disease-free survival from 80% to 90%, with a two-sided significance level of 5%, power of 80%, 3 years of inclusion, 2 years of follow-up, and a 10% drop-out rate. Results: Nine centers in 3 countries included 122 patients in the standard group and 126 patients in the neoadjuvant group from 10/2013 to 11/2021. Forty-four % were female, the median age was 66 years, and 91% had a performance status (PS) of 0, while 9% had a PS of 1. Seventy-three % of the tumors were classified as T3, with a median outgrowth of 11 mm, while 26% were classified as T4 on the baseline CT scan. There were no significant differences in baseline characteristics. The median number of chemotherapy cycles was lower in the neoadjuvant group, 3 (IQR 1-7) vs. 4 (0-8). There were slightly more postoperative complications in the standard group regarding ileus, anastomotic leakage, and length of stay. Postoperatively, more patients in the standard arm had an indication of adjuvant chemotherapy, 88 vs. 72 (p = 0.02). DFS at 2 years was similar in the two arms (p = 0.95, logrank), as was overall survival (OS) (p = 0.95, logrank). Conclusions: Neoadjuvant chemotherapy and standard upfront surgery showed no significant difference in DFS and OS in patients with colon cancer. However, neoadjuvant chemotherapy seemed to have more favorable outcomes in terms of chemotherapy cycles, postoperative complications, and downstaging. CT scan alone may not be sufficient in identifying high-risk patients preoperatively. These findings suggest that neoadjuvant chemotherapy could be considered a viable treatment option for patients with locally advanced colon cancer. Clinical trial information: NCT01918527.

- 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.

- 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.

- Background and aimsThe treatment of locally advanced rectal cancer often consists of neoadjuvant chemoradiotherapy followed by surgery. However, approximately 15% of patients show no response to this neoadjuvant chemoradiotherapy. This systematic review aimed to identify biomarkers of innate radioresistant rectal cancer.MethodThrough a systematic literature search, 125 papers were included and analyzed using ROBINS-I, a Cochrane risk of bias tool for non-randomized studies of interventions. Both statistically significant and nonsignificant biomarkers were identified. Biomarkers mentioned more than once in the results or biomarkers with a low or moderate risk of bias were included as the final results.ResultsThirteen unique biomarkers, three genetic signatures, one specific pathway, and two combinations of two or four biomarkers were identified. In particular, the connection between HMGCS2, COASY, and PI3K-pathway seems promising. Future scientific research should focus on further validating these genetic resistance markers.

- Background: Older or vulnerable patients with metastatic colorectal cancer are seldom included in randomised trials.The multicentre NORDIC9 trial evaluated reduced-dose combination chemotherapy compared with full-dose monotherapy in older, vulnerable patients.Methods: This randomised, open-label phase 2 trial was done in 23 Nordic oncology clinics and included patients aged 70 years or older with previously untreated metastatic colorectal cancer who were not candidates for full-dose combination chemotherapy. Patients were block randomised (1: 1) using a web-based tool to full-dose S-1 (30 mg/m(2) orally twice daily on days 1-14 every 3 weeks) followed by second-line treatment at progression with irinotecan (250 mg/m(2) intravenously on day 1 every 3 weeks or 180 mg/m(2) intravenously on day 1 every 2 weeks) or reduceddose combination chemotherapy with S-1 (20 mg/m(2) orally twice daily on days 1-14) and oxaliplatin (100 mg/m(2) intravenously on day 1 every 3 weeks) followed by second-line treatment at progression with S-1 (20 mg/m(2) orally twice daily on days 1-14) and irinotecan (180 mg/m(2) intravenously on day 1 every 3 weeks). Use of bevacizumab (7.5 mg/kg intravenously on day 1 of each cycle) was optional. Treatment allocation was not masked and randomisation was stratified for institution and bevacizumab. The primary outcome was progression-free survival. Survival analyses were by intention to treat and safety analyses were done on the treated population. This trial is registered with EudraCT, number 2014-000394-39, and is closed to new participants.Findings: From March 9, 2015, to Oct 11, 2017, 160 patients with a median age of 78 years (IQR 76-81) were randomly assigned to full-dose monotherapy (n=83) or reduced-dose combination chemotherapy (n=77). At data cutoff (Sept 1, 2018; median follow-up 23.8 months [IQR 18.8-30.9]), 81 (98%) patients in the full-dose monotherapy group and 71 (92%) patients in the reduced-dose combination group had progressed or died. Median progression-free survival was significantly longer with reduced-dose combination chemotherapy (6.2 months [95% CI 5.3-8.3]) than with full-dose monotherapy (5.3 months [4.1-6.8]; hazard ratio [HR] 0.72 [95% CI 0.52-0.99]; p=0.047). Toxicity was evaluated in 157 patients who received treatment. Significantly more patients in the full-dose monotherapy group (51 [62%] of 82 patients) experienced at least one grade 3-4 adverse event than in the reduced-dose combination group (32 [43%] of 75 patients; p=0.014). Grade 3-4 diarrhoea (12 [15%] vs two [3%]; p=0.018), fatigue (ten [12%] vs three [4%]; p=0.083), and dehydration (five [6%] vs none; p=0.060) were more frequent in the full-dose monotherapy group than in the reduced-dose combination group. Treatment-related deaths occurred in three patients during firstline treatment and three patients during second-line treatment (two in the full-dose monotherapy group vs one in the reduced-dose combination group in both cases).Interpretation: Reduced-dose combination chemotherapy with S-1 and oxaliplatin for older, vulnerable patients with metastatic colorectal cancer was more effective and resulted in less toxicity than full-dose monotherapy with S-1. Reduced-dose combination chemotherapy could be a preferred treatment for this population.
