Popp R, Bansal S, Sharan S, Ahmed SH, Sukniam KB, Raikot S, Popp K, Jiménez PB, Manaise HK, Kowkabany G, Attwood K, Gabriel EM. Disparities in time to treatment initiation for rectal cancer patients: an analysis of demographic and socioeconomic factors. Front Oncol 2024; 14:1327400. [PMID: 38800389 PMCID: PMC11116768 DOI: 10.3389/fonc.2024.1327400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 04/22/2024] [Indexed: 05/29/2024] Open
Abstract
Background This study investigated demographic and socioeconomic factors contributing to disparities in the time to treatment for rectal cancer. Subgroup analysis based on age < 50 and ≥ 50 was performed to identify differences in time to treatment among young adults (age < 50) compared to older adults with rectal cancer. Methods An analysis was performed using data from the National Cancer Database, spanning from 2004 to 2019. The study encompassed 281,849 patients diagnosed with rectal cancer. We compared time intervals from diagnosis to surgery, radiation, and chemotherapy, considering age, sex, race, and socioeconomic variables. Analyses were performed for the entire cohort and for two subgroups based on age (< 50 and ≥ 50). Results Overall, Hispanic patients experienced longer times to surgery, radiation, and chemotherapy compared to non-Hispanic patients (surgery: 94.2 vs. 79.1 days, radiation: 65.0 vs. 55.6 days, chemotherapy: 56.4 vs. 47.8 days, all p < 0.001). Patients with private insurance had shorter times to any treatment (32.5 days) compared to those with government insurance or no insurance (30.6 and 32.5 days, respectively, p < 0.001). Black patients experienced longer wait times for both radiation (63.4 days) and chemotherapy (55.2 days) compared to White patients (54.9 days for radiation and 47.3 days for chemotherapy, both p < 0.001). Interestingly, patients treated at academic facilities had longer times to treatment in surgery, radiation, and chemotherapy compared to those treated at comprehensive and community facilities. When analyzed by age, many of the overall differences persisted despite the age stratification, suggesting that these disparities were driven more by demographic and socioeconomic variables rather than by age. Conclusion Significant differences in the time to treatment for rectal cancer have been identified. Hispanic patients, individuals lacking private insurance, Black patients, and patients receiving care at academic facilities had the longest times to treatment. However, these differences were largely unaffected by the age (< 50 and ≥ 50) subgroup analysis. Further investigation into the causes of these disparities is warranted to develop effective strategies for reducing treatment gaps and enhancing overall care for rectal cancer patients.

Gastroenterology 2023; 164:1152-1164. [PMID: 36841489 DOI: 10.1053/j.gastro.2023.02.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 01/15/2023] [Accepted: 02/09/2023] [Indexed: 02/27/2023]
Abstract
BACKGROUND & AIMS Younger adults (aged <50 years) with colorectal cancer (CRC) may have prolonged delays to diagnosis and treatment that are associated with adverse outcomes. We compared delay intervals by age for patients with CRC in a large population. METHODS This was a population-based study of adults diagnosed with CRC in Ontario, Canada, from 2003 to 2018. We measured the time between presentation and diagnosis (diagnostic interval), diagnosis and treatment start (treatment interval), and the time from presentation to treatment (overall interval). We compared interval lengths between adults aged <50 years, 50 to 74 years, and 75 to 89 years using multivariable quantile regression. RESULTS Included were 90,225 patients with CRC. Of these, 6853 patients (7.6%) were aged <50 years. Younger patients were more likely to be women, present emergently, have stage IV disease, and have rectal cancer compared with middle-aged patients. Factors associated with significantly longer overall intervals included female sex (8.7 days; 95% confidence interval [CI], 6.6-10.9 days) and rectal cancer compared with proximal colon cancer (9.8 days; 95% CI, 7.4-2.2 days). After adjustment, adults aged <50 years had significantly longer diagnostic intervals (4.3 days; 95% CI. 1.3-7.3 days) and significantly shorter treatment intervals (-4.5 days; 95% CI, -5.3 to -3.7 days) compared with middle-aged patients. However, there was no significant difference in the overall interval (-0.6 days; 95% CI, -4.3 to 3.2 days). In stratified models, younger adults with stage IV disease who presented emergently and patients aged >75 years had longer overall intervals. CONCLUSIONS Younger adults present more often with stage IV CRC but have overall similar times from presentation to treatment as screening-eligible older adults.

Abstract
BACKGROUND The incidence of sporadic colorectal cancer (CRC) among individuals <50 years (early-onset CRC) has been increasing in the United States (U.S.) and Puerto Rico. CRC is currently the leading cause of cancer death among Hispanic men and women living in Puerto Rico (PRH). The objective of this study was to characterize the molecular markers and clinicopathologic features of colorectal tumors from PRH to better understand the molecular pathways leading to CRC in this Hispanic subpopulation. METHODS Microsatellite instability (MSI), CpG island methylator phenotype (CIMP), and KRAS and BRAF mutation status were analyzed. Sociodemographic and clinicopathological characteristics were evaluated using Chi-squared and Fisher's exact tests. RESULTS Of the 718 tumors analyzed, 34.2% (n = 245) were early-onset CRC, and 51.7% were males. Among the tumors with molecular data available (n = 192), 3.2% had MSI, 9.7% had BRAF, and 31.9% had KRAS mutations. The most common KRAS mutations observed were G12D (26.6%) and G13D (20.0%); G12C was present in 4.4% of tumors. A higher percentage of Amerindian admixture was significantly associated with early-onset CRC. CONCLUSIONS The differences observed in the prevalence of the molecular markers among PRH tumors compared to other racial/ethnic groups suggest a distinct molecular carcinogenic pathway among Hispanics. Additional studies are warranted.

Quantitative synthetic MRI for predicting locally advanced rectal cancer response to neoadjuvant chemoradiotherapy. Eur Radiol 2023; 33:1737-1745. [PMID: 36380196 DOI: 10.1007/s00330-022-09191-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/08/2022] [Accepted: 09/20/2022] [Indexed: 11/16/2022]
Abstract
OBJECTIVES To investigate the value of pre-treatment quantitative synthetic MRI (SyMRI) for predicting a good response to neoadjuvant chemoradiotherapy (nCRT) in patients with locally advanced rectal cancer. METHODS This prospective study enrolled 63 patients with locally advanced rectal cancer scheduled to undergo preoperative chemoradiotherapy from January 2019 to June 2021. T1 relaxation time (T1), T2 relaxation time (T2), proton density (PD) from synthetic MRI, and apparent diffusion coefficient (ADC) from diffusion-weighted imaging (DWI) were measured. Independent-sample t-test, the Mann-Whitney U test, the Delong test, and receiver operating characteristic curve (ROC) analyses were used to predict the pathologic complete response (pCR) and T-downstaging. RESULTS Among the 63 patients, 19 (30%) achieved pCR and 44 (70%) did not, and 24 (38%) achieved T-downstaging, while 44 (62%) did not. The mean T1 and T2 values were significantly lower in the pCR group compared with those in the non-pCR group and in the T-downstage group compared with those in the non-T-downstage group (all p < 0.05). There were no significant differences in the PD and ADC values between the two groups. There were no significant differences between the mean values of T1 and T2 for predicting pCR after CRT (AUC, 0.767 vs. 0.831, p = 0.37). There were no significant differences between the AUC values of T1 and T2 values for the assessment of post-CRT T-downstaging (AUC, 0.746 vs. 0.820, p = 0.506). CONCLUSIONS In patients with locally advanced rectal cancer, the synthetic MRI-derived T1 relaxation time and T2 relaxation time values are promising imaging markers for predicting a good response to neoadjuvant chemoradiotherapy. KEY POINTS • Mean T1 and T2 values were significantly lower in the pathologic complete response group and the T-downstage group. • There were no significant differences in the proton density and apparent diffusion coefficient values between the two groups.

Abstract
BACKGROUND While early onset colorectal cancer (EOCRC) has previously been defined as CRC in patients younger than age 50, recent screening guidelines have been lowered to 45. With more younger patients aged 45-50 are now being screened, incidence trend and outcomes of very early EOCRC (20-44) remains unclear. METHOD Surveillance, Epidemiology, and End Results database was analyzed between 2006 and 2016 using Joinpoint tool to evaluate annual percentage change (APC) in incident rates, focusing on race/ethnicity and socioeconomic status (SES). Cancer specific survival (CSS) was assessed using univariate and multivariate analysis. RESULTS 41,815 EOCRC patients met inclusion criteria. Incidence has increased significantly in both age groups (APC in age group 20-44 = 1.21 and 45-49 = 1.06). Increase incidence of very early EOCRC was observed in White and Hispanic racial/ethnic groups (ACP 1.68 and 2.63), as well as population from counties with high poverty, unemployment, language barrier, foreign born resident, and high school dropout rates (ACP 2.07, 1.87, 1.21, 1.28 and 2.02 respectively). Further, the 5-year CSS was worse in Black patients, and patients from counties with high poverty, unemployment and high school dropouts rates (Age group 20-44, 63.11%, 66.39%, 67.48% and 66.95% respectively). On multivariate analysis, living in high poverty counties was an independent risk factor for poorer CSS for very early EOCRC (HR 1.20, 95% CI 1.07-1.34, p = 0.002). Multivariate analysis was adjusted by sex, pathology type, site of disease, disease extension and surgical treatment history. CONCLUSION Very early EOCRC incidence increases in White, Hispanic and poor patients, and outcomes are worse for minority and low-income patients. Further study on very early EOCRC is needed among those patients.

Abstract
BACKGROUND Clinical delays may be important contributors to outcomes among younger adults (<50 years) with colorectal cancer (CRC). We aimed to describe delay intervals for younger adults with CRC using health administrative data to understand drivers of delay in this population. METHODS This was a population-based study of adults <50 diagnosed with CRC in Ontario, Canada from 2003 to 2018. Using administrative code-based algorithms (including billing codes), we identified four time points along the pathway to treatment-first presentation with a CRC-related symptom, first investigation, diagnosis date and treatment start. Intervals between these time points were calculated. Multivariable quantile regression was performed to explore associations between patient and disease factors with the median length of each interval. RESULTS 6853 patients aged 15-49 were diagnosed with CRC and met the inclusion criteria. Males comprised 52% of the cohort, the median age was 45 years (IQR 40-47), and 25% had stage IV disease. The median time from presentation to treatment start (overall interval) was 109 days (IQR 55-218). Time between presentation and first investigation was short (median 5 days), as was time between diagnosis and treatment start (median 23 days). The greatest component of delay occurred between first investigation and diagnosis (median 78 days). Women, patients with distal tumours, and patients with earlier stage disease had significantly longer overall intervals. CONCLUSIONS Some younger CRC patients experience prolonged times from presentation to treatment, and time between first investigation to diagnosis was an important contributor. Access to endoscopy may be a target for intervention.

Abstract
Outcome disparities between adults <50 with colorectal cancer (CRC) and older adults may be explained by clinical delays. This study synthesized the literature comparing delays and outcomes between younger and older adults with CRC. Databases were searched until December 2021. We included studies published after 1990 reporting delay in adults <50 that made comparisons to older adults. Comparisons were described narratively and stage between age groups was meta-analyzed. 39 studies were included representing 185,710 younger CRC patients and 1,422,062 older patients. Sixteen delay intervals were compared. Fourteen studies (36%) found significantly longer delays among younger adults, and nine (23%) found shorter delays among younger patients. Twelve studies compared time from symptom onset to diagnosis (N younger = 1538). Five showed significantly longer delays for younger adults. Adults <50 years also had higher odds of advanced stage (16 studies, pooled OR for Stage III/IV 1.76, 95% CI 1.52-2.03). Ten studies compared time from diagnosis to treatment (N younger = 171,726) with 4 showing significantly shorter delays for younger adults. All studies showing longer delays for younger adults examined pre-diagnostic intervals. Three studies compared the impact of delay on younger versus older adult. One showed longer delays were associated with advanced stage and worse survival in younger but not older adults. Longer delays among younger adults with CRC occur in pre-diagnostic intervals.

Abstract
Background The incidence of colorectal cancer is rising in adults <50 years of age. As a primarily unscreened population, they may have clinically important delays to diagnosis and treatment. This study aimed to review the literature on delay intervals in patients <50 years with colorectal cancer (CRC), and explore associations between longer intervals and outcomes. Methods MEDLINE, Embase, and LILACS were searched until December 2, 2021. We included studies published after 1990 reporting any delay interval in adults <50 with CRC. Interval measures and associations with stage at presentation or survival were synthesized and described in a narrative fashion. Risk of bias was assessed using the Newcastle-Ottawa Scale, Institute of Health Economics Case Series Quality Appraisal Checklist, and the Aarhus Checklist for cancer delay studies. Results 55 studies representing 188,530 younger CRC patients were included. Most studies used primary data collection (64%), and 47% reported a single center. Sixteen unique intervals were measured. The most common interval was symptom onset to diagnosis (21 studies; N = 2,107). By sample size, diagnosis to treatment start was the most reported interval (12 studies; N = 170,463). Four studies examined symptoms onset to treatment start (total interval). The shortest was a mean of 99.5 days and the longest was a median of 217 days. There was substantial heterogeneity in the measurement of intervals, and quality of reporting. Higher-quality studies were more likely to use cancer registries, and be population-based. In four studies reporting the relationship between intervals and cancer stage or survival, there were no clear associations between longer intervals and adverse outcomes. Discussion Adults <50 with CRC may have intervals between symptom onset to treatment start greater than 6 months. Studies reporting intervals among younger patients are limited by inconsistent results and heterogeneous reporting. There is insufficient evidence to determine if longer intervals are associated with advanced stage or worse survival. Other This study’s protocol was registered with the Prospective Register of Systematic Reviews (PROSPERO; registration number CRD42020179707).

Abstract
Colorectal cancer is the third most common type of cancer, with high morbidity and mortality rates. In particular, locally advanced rectal cancer (LARC) is difficult to treat and has a high recurrence rate. Neoadjuvant chemoradiotherapy (NCRT) is one of the standard treatment programs of LARC. If the response to treatment and prognosis in patients with LARC can be predicted, it will guide clinical decision‑making. Radiomics is characterized by the extraction of high‑dimensional quantitative features from medical imaging data, followed by data analysis and model construction, which can be used for tumor diagnosis, staging, prediction of treatment response and prognosis. In recent years, a number of studies have assessed the role of radiomics in NCRT for LARC. MRI‑based radiomics provides valuable data and is expected to become an imaging biomarker for predicting treatment response and prognosis. The potential of radiomics to guide personalized medicine is widely recognized; however, current limitations and challenges prevent its application to clinical decision‑making. The present review summarizes the applications, limitations and prospects of MRI‑based radiomics in LARC.

Ann Coloproctol 2021; 38:244-252.

Abstract
Purpose Colorectal cancer (CRC) occurs in all age groups, and the application of treatment may vary according to age. The study was designed to identify the characteristics of CRC by age. Methods A total of 4,326 patients undergoing primary resection for CRC from September 2006 to July 2019 were reviewed. Patient and tumor characteristics, operative and postoperative data, and oncologic outcome were compared Results Patients aged 60 to 69 years comprised the largest age group (29.7%), followed by those aged 50 to 59 and 70 to 79 (24.5% and 23.9%, respectively). Rectal cancer was common in all age groups, but right-sided colon cancer tended to be more frequent in older patients. In very elderly patients, there were significant numbers of emergency surgeries, and the frequencies of open surgery and permanent stoma were greater. In contrast, total abdominal colectomy or total proctocolectomy was performed frequently in patients in their teens and twenties. The elderly patients showed more advanced tumor stages and postoperative ileus. The incidence of adjuvant treatment was low in elderly patients, who also had shorter follow-up periods. Overall survival was reduced in older patients with stages 0 to 3 CRC (P<0.001), but disease-free survival did not differ by age (P=0.391). Conclusion CRC screening at an earlier age than is currently undertaken may be necessary in Korea. In addition, improved surgical and oncological outcomes can be achieved through active treatment of the growing number of elderly CRC patients.

Ullah MF, Fleming CA, Mealy K. Changing trends in age and stage of colorectal cancer presentation in Ireland - From the nineties to noughties and beyond. Surgeon 2018; 16:350-354. [PMID: 29680182 DOI: 10.1016/j.surge.2018.03.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 03/13/2018] [Accepted: 03/18/2018] [Indexed: 01/12/2023]
Abstract
BACKGROUND Recent studies report incidence of colorectal (CRC) in younger adults (<50 years old) is increasing, and these patients are more likely to present with advanced disease. We performed a population-based analysis of these trends in an Irish population. METHODS A retrospective analysis was performed of all patients with histologically confirmed CRC in Ireland, using data from the National Cancer Registry of Ireland (NCRI) [1994-2012, inclusive]. Trends in age-adjusted CRC incidence and stage at presentation were tabulated. Total and average age-adjusted annual percentage change (APC) in CRC rates were calculated using regression analysis, with age adjusted to the European standard population for trend analysis. RESULTS A total of 39,528 cases were included. Throughout the entire study period the most common age of presentation was 70-79 years (32.5%, n = 12 829) with Stage II (27.5%, n = 10 851) CRC. Overall, an increase in incidence of CRC of 2.1% was observed. A significantly increased incidence in patients aged 20-29 years (APC = 9.17%; total change = 4.2%; p = 0.003) was identified from 1994 to 2012. Overall, in patients <50 years, the incidence of stage I colorectal cancer at presentation significantly reduced from 23.5% to 11.6% (p = 0.01). This was associated with a significant parallel rise in stage IV disease (11%-23%, p = 0.02) in this age group. CONCLUSION Increasing incidence of CRC in younger patient groups is observed in an Irish population, with an increase in advanced staged disease at presentation seen. Further studies should focus on identifying causality for this trend and identify potential targets for prevention going forward.
