[PMID: 38834414 DOI: 10.1016/j.hpb.2024.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 04/15/2024] [Accepted: 05/20/2024] [Indexed: 06/06/2024]
Abstract
BACKGROUND Gallbladder cancers (GBCs) occur a decade earlier in India in comparison to the global occurrence, limiting the applicability of existing literature on age adjusted outcomes. METHODS Patients who underwent surgery between 01.01.2010 and 31.12.2020 for GBC were analyzed. Patients were divided into three age groups: group 1(≤40 years), group 2(41-60 years), group 3(>60 years) and their outcomes were compared. RESULTS Total of 6190 patients were treated for suspected or diagnosed GBC with a median age of 57 years. Curative resection was performed in 749 (67.9%) patients, of whom 114 (16.2%), 471 (62.9%), and 164 (21.9%) patients were in groups 1, 2, and 3, respectively. 5-year disease-free survival (DFS) [46.8% vs. 58.5%, p = 0.031] and overall survival (OS)[53.5% vs. 66.6%, p = 0.05] of group 3 were significantly lower than group 1. Patient age (HR 1.021), AJCC stage (HR 6.413), pathologic residual disease in the gallbladder fossa (HR 2.44), and extranodal tumor deposits (HR 1.762) were identified as independent predictors of poor OS. CONCLUSIONS Gallbladder cancers in the Indian population show poorer outcomes with advancing age. Higher proportion of males in the elderly group with a more advanced stage at presentation are plausible reasons for poorer outcomes.

Trends in patterns of treatment and survival of colorectal cancer patients using cancer registry data in Japan: 1995-2015. Cancer Sci 2024; 115:2786-2794. [PMID: 38715379 PMCID: PMC11309936 DOI: 10.1111/cas.16210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/18/2024] [Accepted: 04/24/2024] [Indexed: 08/10/2024] Open
Abstract
Recent advances in treating colorectal cancer (CRC) have increased the importance of multidisciplinary treatment. This study aimed to clarify trends in the treatment and survival of CRC using population-based cancer registry data in Japan. We analyzed the survival of CRC cases diagnosed from 1995 through 2015 from a population-based cancer registry of six prefectures. The year of diagnosis was classified into five periods, and the trends in the detailed categorization of treatments and survival were identified. We calculated net survival and excess hazard of death from cancer using data on 256,590 CRC patients. The use of laparoscopic surgery has been increasing since 2005 and accounts for the largest proportion of treatment types in the most recent period. Net survival of CRC patients diagnosed after 2005 remained high for laparoscopic surgery and endoscopic surgery (endoscopic mucosal resection or endoscopic submucosal dissection). There was an upward trend in treatment with chemotherapy in addition to open and laparoscopic surgery. Using the excess hazard ratio at the regional stage since 2005, there has been a significant improvement in survival in the younger age group and the rectum cancer group. By type of treatment, there was a tendency toward significant improvement in the open surgery + chemotherapy group. We clarified the trends in treating CRC and the associated trends in survival. Continuous survey based on population-based data helps monitor the impact of developments in treatment.

Analysis of the Largest U.S. Cancer Incidence Database, 2001-2020. J Clin Med 2024; 13:1098. [PMID: 38398411 PMCID: PMC10889361 DOI: 10.3390/jcm13041098] [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: 01/20/2024] [Revised: 02/11/2024] [Accepted: 02/12/2024] [Indexed: 02/25/2024] Open
Abstract
(1) Background: While prior data showed an increasing incidence of colorectal cancer (CRC) in young adults, the contribution of adenocarcinoma (ADC) and neuroendocrine tumors (NETs) to this trend is not well studied. Therefore, we conducted a comparative analysis of the incidence rates and time trends of colorectal ADC and NETs in young adults (aged 24-54) using the United States Cancer Statistics (USCS) database. (2) Methods: Age-adjusted CRC incidence rates between 2001 and 2020 were calculated and categorized by sex, histopathology, and stage at diagnosis. Annual percentage change (APC) and average APC (AAPC) were computed via joinpoint regression utilizing weighted Bayesian information criteria to generate the simplest trend. Pairwise comparative analysis of ADC and NETs was conducted using tests of identicalness and parallelism. (3) Results: In this study, 514,875 patients were diagnosed with early-onset-CRC between 2001 and 2020 (54.8% men). While CRC incidence was significantly increased, including both ADC (448,670 patients) and NETs (36,205 patients), a significantly greater increase was seen for NETs (AAPC = 2.65) compared to ADC (AAPC = 0.91), with AAPC difference = 1.73 (p = 0.01) and non-identical non-parallel trends (p-values < 0.001). This was most notable in males (AAPC difference = 1.81, p = 0.03) and for early-stage tumors (AAPC difference = 3.56, p < 0.001). (4) Conclusions: Our study, covering ~98% of the U.S. population provides the first comparative analysis of early-onset CRC histopathological subtypes, showing that the rate of increase of NETs in young adults is much greater than that of ADC. Given that patients with NETs with malignant behavior can experience significant mortality, our findings are importance, highlighting the rapidly increasing NET incidence in young adults and encouraging early screening that can improve outcomes.

Abstract
BACKGROUND The Australian population is ageing, with an increasing number of patients diagnosed with colorectal cancer in their eighth decade. This group represents a challenging cohort to deliver multidisciplinary care, with increased morbidity and mortality related to surgical and oncological therapies. This project aimed to compare surgical and oncological outcomes in octogenarian and non-octogenarian patients with colorectal cancer. METHODS A matched case-control retrospective review of a prospectively maintained institutional database of colorectal cancer patients treated between 2005 and 2021 was conducted. Patient demographics, treatment details, peri-operative complications, and long-term survival were reported. The primary outcome, cancer-specific survival, was investigated using time-to-event analysis and interrogated with multivariate regression. RESULTS There were 747 patients included in the study. There was no difference in five-year cancer-specific survival and recurrence-free survival between cohorts. Multivariate analysis for octogenarians confirmed a significant hazard signal associated with worsening cancer stage and a survival benefit associated with the administration of adjuvant therapy. However, we noted that stage-matched octogenarian patients received less adjuvant treatment compared to non-octogenarians. CONCLUSION Octogenarians undergoing treatment for colorectal cancer have similar cancer-specific survival and recurrence-free survival to non-octogenarians. Our study demonstrates a survival benefit when adjuvant therapy is provided to octogenarians, despite only half of this cohort receiving therapy compared to their younger peers. Further research into adjuvant therapy with surgical resection for CRC in older Australians is required.

Abstract
Background The prevalence of colorectal cancer (CRC) among young individuals is rising worldwide, especially in Malaysia. Investigations are currently employed to distinguish the features of young-onset CRC (YOCRC) from adult-onset CRC (AOCRC). This study aimed to compare the characteristics of patients with YOCRC and AOCRC diagnosed at Hospital Universiti Sains Malaysia (HUSM). Methods This was a retrospective study of CRC cases from January 2013 to December 2021. The details of YOCRC (< 50 years old) and AOCRC (≥ 50 years old) patients were retrieved from the laboratory system and medical records. The Pearson's chi-square test, Fisher's exact test and multiple logistic regression were used to compare the AOCRC and YOCRC cases. Statistical significance was defined at a P-value of ≤ 0.05. Results The AOCRC (254/319, 79.6%) was more prevalent than YOCRC (65/319, 20.4%), with a predominance of males (53.9%) and Malay sub-population (90.2%). AOCRC and YOCRC shared similarities in left-sided location, high occurrence of adenocarcinoma with moderately differentiated histology and advanced stage of diagnosis. More patients with YOCRC (23.1%) had a family history of cancer than patients with AOCRC. YOCRC also differed from AOCRC by having more specific histological subtypes, such as mucinous adenocarcinoma (15.4%) and signet ring carcinoma (6.2%). In addition, patients with YOCRC commonly presented with a low density of tumour-infiltrating lymphocytes (TILs) (60%). Multiple logistic regression showed a family history of CRC (adjusted odds ratio [AOR] = 3.75, P = 0.003) and histological type (AOR = 15.21, P < 0.001) are more likely to cause YOCRC than diabetes (AOR = 0.06, P < 0.001) and hypertension (AOR = 0.14, P < 0.001) comorbidities, which are associated with AOCRC. Conclusion Our descriptive study presented the epidemiological and histopathological characteristics of AOCRC and YOCRC in HUSM, providing current information on distinguishing features between the groups.

Abstract
BACKGROUND The purpose of this study is to employ a competing risk model based on the Surveillance, Epidemiology, and End Results (SEER) database to identify prognostic factors for elderly individuals with sigmoid colon adenocarcinoma (SCA) and compare them with the classic Cox proportional hazards model. METHODS We extracted data from elderly patients diagnosed with SCA registered in the SEER database between 2010 and 2015. Univariate analysis was conducted using cumulative incidence functions and Gray's test, while multivariate analysis was performed using both the Fine-Gray and Cox proportional hazards models. RESULTS Among the 10,712 eligible elderly patients diagnosed with SCA, 5595 individuals passed away: 2987 due to sigmoid colon adenocarcinoma and 2608 from other causes. The results of one-way Gray's test showed that age, race, marital status, AJCC stage, differentiation grade, tumor size, surgical status, liver metastasis status, lung metastasis status, brain metastasis status, radiotherapy status, and chemotherapy status all affected the prognosis of SCA (P < .05). Multivariate analysis showed that sex, age, race, marital status, and surgical status affected the prognosis of SCA (P < .05). Multifactorial Fine-Gray analysis revealed that key factors influencing the prognosis of SCA patients include age, race, marital status, AJCC stage, grade classification, surgical status, tumor size, liver metastasis, lung metastasis, and chemotherapy status (P < .05). CONCLUSION Data from the SEER database were used to more accurately estimate CIFs for sigmoid colon adenocarcinoma-specific mortality and prognostic factors using competing risk models.

Abstract
PURPOSE The number of elderly patients with a diagnosis of colorectal cancer (CRC) is increasing. Considering short life expectancy and multiple comorbidities, surgery may not always be the best treatment option. METHODS We included all consecutive patients aged 80 years and older who underwent elective resection for CRC following Enhanced Recovery after Surgery (ERAS) protocol between January 2011 and May 2021. The primary endpoint was overall survival, secondary endpoints were 30-day morbidity, and the rate of return to pre-operative living conditions 3 months after surgery. RESULTS Ninety-four patients were included. Mean age was 84.6 ± 3.6 years, 49 patients (52%) were female. Most patients (77.6%) were ASA score ≥ 3. Laparoscopic resections were performed in 85 patients (90.4%), involving 69 (73.4%) colonic and 25 (26.6%) rectal resections. A stoma was constructed in 22 patients (23%), and reversed in 12 (54.5%). Twenty-two patients (23.4%) experienced a Clavien-Dindo ≥ 3 complication, and 2 patients (2.1%) died. The median length of hospital stay was 8 (interquartiles: 6-15) days. Sixty-six patients (70.2%) were discharged home directly and 26 (27.7%) to rehabilitation or postacute care institutes. At three months after surgery, eighty-two patients (96.5%) returned to their pre-operative living conditions directly or after short-term rehabilitation. Mean follow-up was 53 ± 33 months, estimated 5-year overall survival was 60.3% (95%CI 49.5-71.1%), and disease-free survival was 86.3% (95%CI 78.1-94.4%). CONCLUSIONS Our study suggests that elderly patients undergoing elective surgery have a high potential to return to preoperative living conditions and good overall- and disease-free survivals, despite significant postoperative morbidity.

Abstract
Colorectal cancer (CRC) is a leading cause of death from cancer in Canada. Early detection of CRC remains crucial in managing disease prognosis and improving patient survival. It can also facilitate prevention, screening, and treatment before the disease progresses to a chronic stage. In this study, we developed a strategy for identifying colon cancer biomarkers from both gene expression and gene pair correlation. Using the RNA-Seq dataset TCGA-COAD, a panel of 71 genes, including the 20 most upregulated genes, 20 most downregulated genes and 31 genes involved in the most significantly altered gene pairs, were selected as potential biomarkers for colon cancer. This signature set of genes could be used for early diagnosis. Furthermore, this strategy could be applied to other types of cancer.

Prognostic Analysis of LncRNA MCM3AP-AS1 in Colorectal Cancer and the Mechanism of Its Effect on Tumor Cell Activity. BIOMED RESEARCH INTERNATIONAL 2022; 2022:1616370. [PMID: 36172487 PMCID: PMC9512606 DOI: 10.1155/2022/1616370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 08/29/2022] [Accepted: 09/07/2022] [Indexed: 11/18/2022]
Abstract
To determine the clinical prognostic significance of lncRNA MCM3AP-AS1 in colorectal cancer (CRC) and its preliminary mechanism, 43 CRC patients and 48 healthy individuals were analyzed. Peripheral blood MCM3AP-AS1 was quantified via qRT–PCR in CRC patients at admission and 2 h after surgery and in healthy individuals. Human colon cancer cells (HCT116 and SW480) were transfected with shRNAs targeting upregulation of MCM3AP-AS1 expression (named as sh-MCM3AP-AS1 group) and corresponding negative RNAs (named as sh-MCM3AP-AS1 group). Additionally, the cells were then treated either with 50 mM of the VEGF-specific inhibitor PTK787 (Selleck, USA) (named as inhibition group) or normal saline as a control (named as control group). Before therapy, CRC patients presented a higher MCM3AP-AS1 level than healthy individuals (P < 0.05), and the sensitivity and specificity of MCM3AP-AS1 in predicting the occurrence of CRC were 65.12% and 83.33%, respectively (P < 0.001). After therapy, CRC patients presented a decrease in MCM3AP-AS1 levels, and recurrence was higher in patients who died (P < 0.05). Additionally, the high MCM3AP-AS1 expression group presented a higher mortality than the low MCM3AP-AS1 expression group (P < 0.05). In an in vitro assay, CRC cells showed a higher MCM3AP-AS1 level than CCD-18Co cells, and the sh-MCM3AP-AS1 group presented decreased cell proliferation and invasiveness, whereas the levels apoptosis-associated proteins were increased (P < 0.05). Moreover, the VEGF and VEGFR2 mRNA levels were increased in CRC cells, and VEGF/VEGFR2 pathway-associated proteins were inhibited in the sh-MCM3AP-AS1 group (P < 0.05). Moreover, treatment with PTK787 decreased cell proliferation and invasivness but increased the levels of apoptosis-associated proteins (P < 0.05).

Abstract
Colorectal cancer (CRC) to date still ranks as one of the deadliest cancer entities globally, and despite recent advances, the incidence in young adolescents is dramatically increasing. Lipid metabolism has recently received increased attention as a crucial element for multiple aspects of carcinogenesis and our knowledge of the underlying mechanisms is steadily growing. However, the mechanism how fatty acid metabolism contributes to CRC is still not understood in detail. In this review, we aim to summarize our vastly growing comprehension and the accompanied complexity of cellular fatty acid metabolism in CRC by describing inputs and outputs of intracellular free fatty acid pools and how these contribute to cancer initiation, disease progression and metastasis. We highlight how different lipid pathways can contribute to the aggressiveness of tumors and affect the prognosis of patients. Furthermore, we focus on the role of lipid metabolism in cell communication and interplay within the tumor microenvironment (TME) and beyond. Understanding these interactions in depth might lead to the discovery of novel markers and new therapeutic interventions for CRC. Finally, we discuss the crucial role of fatty acid metabolism as new targetable gatekeeper in colorectal cancer.
