Abstract
The side effects of cancer therapy continue to cause significant health and cost burden to the patient, their friends and family, and governments. A major barrier in the way in which these side effects are managed is the highly siloed mentality that results in a fragmented approach to symptom control. Increasingly, it is appreciated that many symptoms are manifestations of common underlying pathobiology, with changes in the gastrointestinal environment a key driver for many symptom sequelae. Breakdown of the mucosal barrier (mucositis) is a common and early side effect of many anti-cancer agents, known to contribute (in part) to a range of highly burdensome symptoms such as diarrhoea, nausea, vomiting, infection, malnutrition, fatigue, depression, and insomnia. Here, we outline a rationale for how, based on its already documented effects on the gastrointestinal microenvironment, medicinal cannabis could be used to control mucositis and prevent the constellation of symptoms with which it is associated. We will provide a brief update on the current state of evidence on medicinal cannabis in cancer care and outline the potential benefits (and challenges) of using medicinal cannabis during active cancer therapy.

Gaffley M, Hsieh MC, Li T, Yi Y, Gibbs JF, Wu XC, Gallagher J, Chu QD. Rural versus urban commuting patients with stage III colon cancer: is there a difference in treatment and outcome? Surg Endosc 2023; 37:9441-9452. [PMID: 37697118 DOI: 10.1007/s00464-023-10406-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 08/14/2023] [Indexed: 09/13/2023]
Abstract
BACKGROUND To evaluate if there are differences in outcomes for patients with stage III colon cancer in those from urban vs. rural commuting areas. METHODS Data were evaluated on patients diagnosed with stage III colon cancer between 2012 and2018 from the Louisiana Tumor Registry. Patients were classified into rural and urban groups. Data on overall survival, time from diagnosis to surgery and time from surgery to chemotherapy, and sociodemographic factors (including race, age, and poverty level) were recorded. RESULTS Of 2652 patients identified, 2159 were urban (81.4%) and 493 rural (18.6%). No age difference between rural and urban patients (p = 0.56). Stage IIIB accounted for 66.7%, followed by IIIC (21.6%) and IIIA (11%), with a significant difference between rural and urban patients based on stage (p = 0.02). There was no difference in the extent of surgery (p = 0.34) or tumor size (p = 0.72) between urban and rural settings. No difference in undergoing chemotherapy (p = 0.12). There was a statistically significant difference in receiving timely treatment for hospital volume (p < 0.0001) and poverty level (p < 0.0001), but no difference in time from diagnosis to surgery (p = 0.48), and time from surgery to chemotherapy (p = 0.27). Non-Hispanic Blacks were less likely to receive timely treatment when compared with non-Hispanic Whites for both surgery and adjuvant chemotherapy, (aHR 0.91, 95% CI 0.83-0.99) and (aHR 0.86, 95% CI 0.77-0.97), respectively. There was no difference in Kaplan-Meier overall survival curves comparing rural vs. urban patients (p = 0.77). CONCLUSIONS There was no statistical difference in overall survival, time to surgery, and time to adjuvant chemotherapy between rural and urban patients with Stage III colon cancer.

The Gut Microbiota Metabolite Urolithin B Prevents Colorectal Carcinogenesis by Remodeling Microbiota and PD-L1/HLA-B. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2023; 2023:6480848. [PMID: 36778211 PMCID: PMC9908333 DOI: 10.1155/2023/6480848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 12/19/2022] [Accepted: 12/20/2022] [Indexed: 02/05/2023]
Abstract
Colorectal cancer has risen to the third occurring cancer in the world. Fluorouracil (5-Fu), oxaliplatin, and cisplatin are the most effective chemotherapeutic agents for clinical chemotherapy. Nevertheless, due to chemotherapeutic drug resistance, the survival rate of patients with CRC remains very low. In this study, we used the inflammation-induced or mutation-family-inherited murine CRC models to study the anticancer and immunotherapy effects of urolithin B (UB), the final metabolite of polyphenols in the gastrointestinal tract. The label-free proteomics analysis and the gene ontology (GO) classifications were used to test and analyze the proteins affected by UB. And 16S rDNA sequencing and flow cytometry were utilized to uncover gut microbiome composition and immune defense improved by UB administration. The results indicated that urolithin B prevents colorectal carcinogenesis by remodeling gut microbial and tumor immune microenvironments, such as HLA-B, NK cells, regulatory T cells, and γδ TCR cells, and decreasing the PD-L1. The combination of urolithin B with first-line therapeutic drugs improved the colorectal intestinal hematochezia by shaping gut microbiota, providing a strategy for the treatment of immunotherapy treatment for CRC treatments. UB combined with anti-PD-1 antibody could inhibit the growth of colon cancer. Urolithin B may thus contribute to anticancer treatments and provide a high immune response microenvironment for CRC patients' further immunotherapy.

Abstract
Background Previous literature demonstrates correlations between comorbidities and failure to complete adjuvant chemotherapy. Frailty and socioeconomic disparities have also been implicated in affecting cancer treatment outcomes. This study examines the effect of demographics, comorbidities, frailty, and socioeconomic status on chemotherapy completion rates in colorectal cancer patients. Methods This was an observational case-control study using retrospective data from Stage II and III colorectal cancer patients offered chemotherapy between January 01, 2013 and January 01, 2018. Data was obtained using the cancer registry, supplemented with chart review. Patients were divided based on treatment completion and compared with respect to comorbidities, age, Eastern Cooperative Oncology Group (ECOG) score, and insurance status using univariate and multivariate analyses. Results 228 patients were identified: 53 Stage II and 175 Stage III. Of these, 24.5% of Stage II and 30.3% of Stage III patients did not complete chemotherapy. Neither ECOG status nor any comorbidity predicted failure to complete treatment. Those failing to complete chemotherapy were older (64.4 vs 60.8 years, P = .043). Additionally, those with public assistance or self-pay were less likely to complete chemotherapy than those with private insurance ( P = .049). Both factors (older age/insurance status) remained significant on multivariate analysis (increasing age at diagnosis: OR 1.03, P =.034; public insurance: OR 1.84, P = .07; and self-pay status: OR 4.49, P = .03). Conclusions No comorbidity was associated with failure to complete therapy, nor was frailty, as assessed by ECOG score. Though frailty was not significant, increasing age was, possibly reflecting negative attitudes toward chemotherapy in older populations. Insurance status also predicted failure to complete treatment, suggesting disparities in access to treatment, affected by socioeconomic factors.
