Global application of National Comprehensive Cancer Network resource-stratified guidelines for systemic treatment of colon cancer: a population-based, customisable model for cost, demand, and procurement

Comprehensive Multi-Omics Analysis of Copper Metabolism Related Molecular Subtypes and Prognostic Risk Stratification in Colon Adenocarcinoma

Colon adenocarcinoma (COAD) is the most common subtype of colorectal cancer, originating from glandular cells in the colon. Despite diagnostic and therapeutic advances, its prognosis remains poor. Copper, an essential micronutrient, is involved in tumorigenesis and other biological processes. In this study, we identified copper metabolism-related genes (CMRG) associated with COAD prognosis from TCGA and GEO databases and constructed a CMRG-based risk model. We assessed its clinical relevance through analyses of immune infiltration, immunotherapy response, and drug sensitivity. Single-cell sequencing revealed the spatial and cellular distribution of CMRG in COAD tissues, providing insight into their roles in the tumour microenvironment. COX19 was selected for further validation, and in vitro experiments (western blot, PCR, siRNA, colony formation, and Transwell assays) confirmed its role in promoting COAD cell invasion and proliferation. These findings highlight the involvement of copper metabolism in COAD progression and suggest potential targets for therapy.

Low-Risk Febrile Neutropenia Management: An Audit of Practice in a UK Cancer Center

BACKGROUND

Febrile neutropenia (FN) is a known complication of chemotherapy. Guidelines from American Society of Clinical Oncology and National Institute for Health and Care Excellence support outpatient management for low-risk FN patients; however, implementation varies across United Kingdom (UK) cancer centers. While some centers have adopted outpatient pathways, others continue to rely on inpatient care, leading to inequities in FN management. Standardized use of risk stratification tools, such as the Multinational Association of Supportive Care in Cancer (MASCC) and Clinical Index of Stable Febrile Neutropenia (CISNE) scores, is essential for equitable FN management. Globally, oncology nurses play a critical role in optimizing FN care to reduce hospital admissions in low-risk patients.

OBJECTIVES

This retrospective study aimed to determine the proportion of FN patients classified as low risk using the MASCC and CISNE scores, evaluate their clinical outcomes, and assess the feasibility of outpatient management.

METHODS

A retrospective audit of adult patients with solid tumors admitted with FN was conducted at a UK NHS cancer center over a 6-month period. Data on MASCC/CISNE scores, clinical outcomes, length of stay, and antibiotic use were extracted from electronic records. Statistical analyses, including Mann-Whitney U and Kruskal-Wallis tests, were performed. A cost analysis estimated potential financial savings from outpatient management.

RESULTS

Of 18 FN admissions, 11 (61.1%) were classified as low risk by MASCC, and 6 (54.5%) of these were also low risk by CISNE. No adverse events were observed. The median length of stay was shorter for MASCC low-risk patients v high-risk patients (6 v 8 days, P = .043). Estimated cost savings were approximately £30,000 over 6 months. Some UK centers have successfully implemented outpatient FN pathways, but variation in risk stratification and systemic inequities exist.

CONCLUSIONS

Oncology nurses are key to standardizing FN risk assessment and advocating for equitable outpatient FN care. Addressing disparities in low-risk FN management may optimize healthcare resources and improve patient experience.

Comparison between laparoscopic complete mesocolic excision and D2 radical operation in colon carcinoma resection: A propensity score matching analysis

BACKGROUND

Surgery remains the most effective treatment for colon cancer. However, there are still controversies regarding the tumor treatment effect, prognosis, and perioperative impact of complete mesocolic excision (CME) surgery in colon carcinoma resection.

OBJECTIVE

This study aims to compare laparoscopic complete mesocolic excision (LCME) and traditional open D2 radical surgery in colon carcinoma resection through a retrospective analysis using 1:1 propensity score matching (PSM).

METHODS

98 cases undergoing LCME or open D2 colon carcinoma resection at our hospital from January 2014 to November 2021 were retrospectively collected. After excluding cases and 1:1 matching using PSM based on baseline clinical data, 86 patients were assigned in research queue. 43 patients were in each group. Two groups were compared for general clinical baseline indicators. Surgical results and postoperative adverse events of patients were also compared. Disease-free survival (DFS) rate and overall survival (OS) rate was analyzed.

RESULTS

After 1:1 PSM matching, there was no statistically significant differences in baseline data between the LCME group and D2 group (P> 0.05). LCME was characterized by longer total duration of surgery (P< 0.001), less intraoperative bleeding volume (P< 0.001), more postoperative drainage fluid volume (P< 0.001), greater number of lymph nodes retrieved (P= 0.014). No statistically differences was observed regarding intraoperative blood transfusion, hospital stay, Clavien-Dindo complicating disease classification (all P> 0.05), 1 and 3-year DFS rate (P= 0.84) and OS rate (P⩾ 0.1).

CONCLUSION

LCME had a longer duration of surgery but less intraoperative bleeding volume and more postoperative drainage fluid volume and retrieved lymph nodes compared to D2 radical surgery. LCME surgery is comparable to D2 surgery in terms of postoperative prognosis, but LCME surgery shows a positive trend in the overall survival curve.

Addressing and mitigating the high costs of extravasation and infiltration to patients and healthcare organisations

Infiltration and extravasation injuries are a common complication of intravenous therapy and vascular access practice. However, there remains a lack of awareness and understanding surrounding these injuries. The first of two articles (Barton, 2024) reported on data from a study showing that the use of ivWatch infusion site surveillance technology can dramatically reduce the number of infiltration and extravasation injures with peripheral intravenous infusions of vesicant preparations, which can improve patient safety and have a positive financial impact. This second of two articles on infiltration and extravasation examines the financial and academic burdens.

Real-world treatment costs of first-line treatment for metastatic colorectal cancer: a survey of the JCOG colorectal cancer study group

BACKGROUND

Although treatment outcomes for metastatic colorectal cancer (mCRC) have dramatically improved over the past few decades, drug costs have also significantly increased. This study aimed to investigate which first-line treatment regimens for mCRC are actually used (frequency) in Japanese practice and at what cost.

METHODS

We collected data on patients with mCRC who received first-line treatment at 37 institutions of the Japan Clinical Oncology Group Colorectal Cancer Study Group from July 2021 to June 2022, and calculated the cost of regimens. The cost per month of each regimen was estimated based on standard usage, assuming a patient with a weight of 70 kg and a body surface area of 1.8 m2. We categorized the regimens into very high-cost (≥1 000 000 Japanese yen [JPY]/month), high-cost (≥500 000 JPY/month), and others (<500 000 JPY/month).

RESULTS

The study included 1880 participants, 24% of whom were ≥ 75 years. Molecular targeted containing regimens were received by 78% of the patients. The most frequently used regimen was the doublet regimen (fluoropyrimidine with either oxaliplatin or irinotecan) plus bevacizumab (43%), followed by doublet plus cetuximab or panitumumab (21%). The cost of molecular targeted drugs-containing regimens (ranging from 85 406 to 843 602 JPY/month) is much higher than that of only cytotoxic drug regimens (ranging from 17 672 to 51 004 JPY/month). About 16% received high-cost treatments that included panitumumab-containing regimens and pembrolizumab (17% of patients aged ≤74 years and 11% of patients aged ≥75 years).

CONCLUSION

About 16% of mCRC patients received first-line treatment with regimens costing >500 000JPY/month, and molecular targeted drugs being the main drivers of cost.

Chinese Medicine in Colorectal Cancer Treatment: From Potential Targets and Mechanisms to Clinical Application

Colorectal cancer (CRC) is a global health challenge necessitating innovative therapeutic strategies. There is an increasing trend toward the clinical application of integrative Chinese medicine (CM) and Western medicine approaches. Chinese herbal monomers and formulations exert enhanced antitumor effects by modulating multiple signaling pathways in tumor cells, including inhibiting cell proliferation, inducing apoptosis, suppressing angiogenesis, reversing multidrug resistance, inhibiting metastasis, and regulating immunity. The synergistic effects of CM with chemotherapy, targeted therapy, immunotherapy, and nanovectors provide a comprehensive framework for CRC treatment. CM can mitigate drug toxicity, improve immune function, control tumor progression, alleviate clinical symptoms, and improve patients' survival and quality of life. This review summarizes the key mechanisms and therapeutic strategies of CM in CRC, highlighting its clinical significance. The potential for CM and combination with conventional treatment modalities is emphasized, providing valuable insights for future research and clinical practice.

Clinical characteristics and risk factors of post-operative intestinal flora disorder following laparoscopic colonic surgery: A propensity-score-matching analysis

BACKGROUND

Intestinal flora disorder (IFD) poses a significant challenge after laparoscopic colonic surgery, and no standard criteria exists for its diagnosis and treatment.

AIM

To analyze the clinical features and risk factors of IFD.

METHODS

Patients with colon cancer receiving laparoscopic surgery were included using propensity-score-matching (PSM) methods. Based on the occurrence of IFD, patients were categorized into IFD and non-IFD groups. The clinical characteristics and treatment approaches for patients with IFD were analyzed. Multivariate regression analysis was performed to identify the risk factors of IFD.

RESULTS

The IFD incidence after laparoscopic surgery was 9.0% (97 of 1073 patients). After PSM, 97 and 194 patients were identified in the IFD and non-IFD groups, respectively. The most common symptoms of IFD were diarrhea and abdominal, typically occurring on post-operative days 3 and 4. All patients were managed conservatively, including modulation of the intestinal flora (90.7%), oral/intravenous application of vancomycin (74.2%), and insertion of a gastric/ileus tube for decompression (23.7%). Multivariate regression analysis identified that pre-operative intestinal obstruction [odds ratio (OR) = 2.79, 95%CI: 1.04-7.47, P = 0.041] and post-operative antibiotics (OR = 8.57, 95%CI: 3.31-23.49, P < 0.001) were independent risk factors for IFD, whereas pre-operative parenteral nutrition (OR = 0.12, 95%CI: 0.06-0.26, P < 0.001) emerged as a protective factor.

CONCLUSION

A stepwise approach of probiotics, vancomycin, and decompression could be an alternative treatment for IFD. Special attention is warranted post-operatively for patients with pre-operative obstruction or early use of antibiotics.

Symptom experiences and influencing factors in patients undergoing chemotherapy for gastrointestinal cancers: a qualitative study

Objective

To explore the symptom experiences and influencing factors of gastrointestinal (GI) cancer patients on chemotherapy (CTX) in China.

Methods

Semi-structured interviews were conducted with 13 GI cancer patients undergoing CTX. Following the Colaizzi 7-step analysis method, the interview data were read carefully, meaningful statements related to the research questions were extracted, coded, collected, and described in detail, and the authenticity of the theme was verified.

Results

Nine themes were grouped into two main areas including the characteristics of symptom experiences and influences on symptom experiences.

Conclusion

The symptom experiences of patients undergoing CTX for GI cancer is poor and influenced by multiple factors. Nurses need to pay attention to the assessment and monitoring of CTX-related symptoms, improve symptom recognition, enhance doctor-patient communication and social support, explore intelligent management methods, and increase the efficiency of healthcare services to improve patients' symptom experience.

Mn(II) Optimized Sono/Chemodynamic Effect of Porphyrin-Metal-Organic Framework Nanosheets for MRI-Guided Colon Cancer Therapy and Metastasis Suppression

Sonodynamic therapy (SDT) offers a remarkable non-invasive ultrasound (US) treatment by activating sonosensitizer and generating reactive oxygen species (ROS) to inhibit tumor growth. The development of multifunctional, biocompatible, and highly effective sonosensitizers remains a current priority for SDT. Herein, the first report that Mn(II) ions chelated Gd-TCPP (GMT) nanosheets (NSs) are synthesized via a simple reflux method and encapsulated with pluronic F-127 to form novel sonosensitizers (GMTF). The GMTF NSs produce a high yield of ROS under US irradiation due to the decreased highest occupied molecular orbital-lowest unoccupied molecular orbital gap energy (2.7-1.28 eV). Moreover, Mn(II) ions endow GMTF with a fascinating Fenton-like activity to produce hydroxyl radicals in support of chemodynamic therapy (CDT). It is also effectively used in magnetic resonance imaging (MRI) with high relaxation rate (r 1: 4.401 mM-1 s-1) to track the accumulation of NSs in tumors. In vivo results indicate that the SDT and CDT in combination with programmed cell death protein 1 antibody (anti-PD-1) show effective metastasis prevention effects, and 70% of the mice in the GMTF + US + anti-PD-1 group survived for 60 days. In conclusion, this study develops a sonosensitizer with promising potential for utilizing both MRI-guided SDT and CDT strategies.
