Prognostic role of immunohistochemical PTEN (phosphatase and tensin homolog) expression and PTEN (rs701848) genotypes among Egyptian patients with different stages of colorectal cancer. J Cancer 2024; 15:5046-5057. [PMID: 39132163 PMCID: PMC11310872 DOI: 10.7150/jca.97553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2024] [Accepted: 07/07/2024] [Indexed: 08/13/2024] Open
Abstract
Colorectal cancer (CRC) is the third most frequent cancer worldwide and the second major cause of cancer-related death. Thus, we attempted to ascertain the relationship between the genotype and allele frequencies of phosphatase and tensin homolog (PTEN) and immunohistochemical PTEN expression with clinicopathological characteristics in patients with CRC. 150 individuals were allocated into two groups for this cross-sectional randomized case-control study: Group I consisted of 100 patients with histopathologically proven CRC of various stages. Group II: Fifty healthy volunteers. Genetic analysis of PTEN (rs701848 T / C) single nucleotide polymorphism (SNP) was performed using TaqManTM assays and real-time PCR, while PTEN expressions were assessed using immunohistochemical staining. PTN SNP genotypes and alleles did not significantly differ between CRC patients and controls. PTEN expression was lost in 28% of CRC patients, while all healthy controls exhibited PTEN expression. Negative PTEN expression was present in 16 (80%) of stage IV CRC cases, 9 (23.7%) of stage III cases, 3 (37.5%) of stage II cases, and none of stage I cases. It was shown that PTEN expression was weakly positive, moderately positive, and strongly positive in 15, 10, and 9 (respectively) cases of CRC stage I. However, the expression was only weekly positive in 4 (20%) of the patients in stage IV. In the stage IV group, neither moderately nor strongly positive PTEN expressions were found. So, Among Egyptians, the emergence or course of colorectal cancer is unrelated to the PTEN gene mutation. However, the formation and progression of CRC may be influenced by weak or lost PTEN expression.

Oxaliplatin-Based Adjuvant Chemotherapy in Older Patients With Stage III Colon Cancer: An ACCENT/IDEA Pooled Analysis of 12 Trials. J Clin Oncol 2024; 42:2295-2305. [PMID: 38547438 DOI: 10.1200/jco.23.01326] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 11/30/2023] [Accepted: 02/28/2024] [Indexed: 06/28/2024] Open
Abstract
PURPOSE A number of studies suggest that older patients may have reduced or no benefit from the addition of oxaliplatin to fluoropyrimidines as adjuvant chemotherapy for stage III colon cancer (CC). MATERIALS AND METHODS We studied the prognostic impact of age, as well as treatment adherence/toxicity patterns according to age, in patients with stage III CC who received 3 or 6 months of infusional fluorouracil, leucovorin, and oxaliplatin/capecitabine and oxaliplatin (CAPOX) on the basis of data collected from trials from the ACCENT and IDEA databases. Associations between age and time to recurrence (TTR), disease-free survival (DFS), overall survival (OS), survival after recurrence (SAR), and cancer-specific survival (CSS) were assessed by a Cox model or a competing risk model, stratified by studies and adjusted for sex, performance status, T and N stage, and year of enrollment. RESULTS A total of 17,909 patients were included; 24% of patients were age older than 70 years (n = 4,340). Patients age ≥70 years had higher rates of early treatment discontinuation. Rates of grade ≥3 adverse events were similar between those older and younger than 70 years, except for diarrhea and neutropenia that were more frequent in older patients treated with CAPOX (14.2% v 11.2%; P = .01 and 12.1% v 9.6%; P = .04, respectively). In multivariable analysis, TTR was not significantly different between patients <70 years and those ≥70 years, but DFS, OS, SAR, and CSS were significantly shorter in those patients ≥70 years. CONCLUSION In patients ≥70 years with stage III CC fit enough to be enrolled in clinical trials, oxaliplatin-based adjuvant chemotherapy was well tolerated and led to similar TTR compared with younger patients, suggesting similar efficacy. TTR may be a more appropriate end point for efficacy in this patient population.

Abstract
OBJECTIVE Physical activity (PA) has emerged as an important element of supportive care for cancer patients, but few patients engage with exercise. Considering that autonomy support is associated with healthy lifestyles, it would be useful to know the specific autonomy-supportive techniques that can help to encourage PA in colorectal cancer (CRC) patients. This study aims to qualitatively explore autonomy support perceptions through a self-determination-theory-based exercise program (FIT-CANCER) with CRC patients during chemotherapy treatment. METHODS AND MEASURES A total of 27 participants were included, 16 CRC patients, six relatives, and five healthcare professionals. Qualitative data from semi-structured interviews and observational field notes were analyzed with thematic analysis. RESULTS Three main themes were identified: Healthcare professionals encouraging enrollment in the exercise program, Relatives supporting attendance to the exercise sessions, Exercise instructor favoring adherence to the exercise program. The different subthemes showed autonomy-supportive techniques from these social agents to promote CRC patients' participation in the exercise program. CONCLUSION The present research showed the importance of autonomy support from healthcare professionals, relatives and the exercise instructor to promote the initiation and maintenance of CRC patients' PA behavior and improve their quality of life, health and well-being.

Abstract
Background Due to the novel advanced screening methods, the number of patients diagnosed with stage I colorectal cancer (CRC) is increasing. This retrospective cohort study aimed to identify recurrence and survival risk factors of patients with stage I CRC after surgery. Materials and methods Patients with stage I CRC were evaluated, and their demographic and clinicopathologic variables were recorded. The log-rank test assessed the association of variables with overall survival (OS), recurrence-free survival (RFS), local recurrence, and distant metastasis. Results The median overall survival period was 51 months. The recurrence rate was 13.7%: 7.2% local and 9.3% distant recurrence. One-, two-, three-, and five-year RFS were 92%, 89%, 87%, and 83%, respectively, and OS were 96%, 93%, 90%, and 89%, respectively. Local and distant recurrence rates were higher in patients with higher tumor grades. Additionally, RFS and OS were worse in patients with higher tumor grades, and perforation was associated with worse OS. Conclusions The determinants of survival and recurrence identified in the present study can be used to improve patient outcomes by early diagnosis and appropriate management of high-risk patients.

Abstract
BACKGROUND Although malnutrition has been linked to worse healthcare outcomes, the broader context of food environments has not been examined relative to surgical outcomes. We sought to define the impact of food environment on postoperative outcomes of patients undergoing resection for colorectal cancer (CRC). METHODS Patients who underwent surgery for CRC between 2014 and 2020 were identified from the Medicare database. Patient-level data were linked to the United States Department of Agriculture data on food environment. Multivariable regression was used to examine the association between food environment and the likelihood of achieving a textbook outcome (TO). TO was defined as the absence of an extended length of stay (≥75th percentile), postoperative complications, readmission, and mortality within 90 days. RESULTS A total of 260,813 patients from 3017 counties were included in the study. Patients from unhealthy food environments were more likely to be Black, have a higher Charlson Comorbidity Index, and reside in areas with higher social vulnerability (all P < .01). Patients residing in unhealthy food environments were less likely to achieve a TO than that of patients residing in the healthiest food environments (food swamp: 48.8% vs 52.4%; food desert: 47.9% vs 53.7%; P < .05). On multivariable analysis, individuals residing in the unhealthy food environments had lower odds of achieving a TO than those of patients living in the healthiest food environments (food swamp: OR, 0.86; 95% CI, 0.83-0.90; food desert: OR, 0.79; 95% CI, 0.76-0.82); P < .05). CONCLUSION The surrounding food environment of patients may serve as a modifiable sociodemographic risk factor that contributes to disparities in postoperative CRC outcomes.

Abstract
AIM Encapsulating epigallocatechin-3-gallate (EGCG) in pH-sensitive polymeric nanoparticles for targeted delivery of drugs could revolutionize colorectal cancer treatment. MATERIALS & METHODS Nanoparticles were synthesized to release drugs at colon pH. Dynamic light scattering measured their average diameter and ζ-potential, while differential scanning calorimetry and x-ray diffraction assessed EGCG encapsulation. RESULTS The nanoparticles showed stability and bioavailability in the gastrointestinal tract, efficiently encapsulating and releasing over 93% of EGCG at pH 7.2. They enhanced cytotoxicity against HT-29 cells and demonstrated antibacterial properties, increasing apoptosis and cell cycle arrest. CONCLUSION The study underscores the potential of nanoparticles in enhancing EGCG delivery for colorectal cancer therapy, aiming to minimize side effects and improve therapeutic outcomes.

Abstract
OBJECTIVES This study investigated the potential of combining PTT with dendritic cell (DC)-based immunotherapy and anti-PD-L1 immune checkpoint blockade (ICB) therapy against colorectal cancer and elucidated the underlying mechanisms. METHODS The CT26 tumour-bearing mice were divided into seven treatment groups: control, atezolizumab (A), dendritic cells (DC), pAuNSs-mediated PTT (PTT), PTT combined with atezolizumab (PTT + A), PTT combined with dendritic cells (PTT + DC), and PTT combined with dendritic cells and atezolizumab (PTT + DC + A). Therapeutic efficacy was monitored. RESULTS PTT upregulated most immune cell membrane receptor genes, including PD-L1, and downregulated genes associated with antigen presentation and T cell activation. Although the PTT + A and PTT + DC treatments showed partial tumour growth retardation, the combination of PTT with DCs and atezolizumab (PTT + DC + A) exhibited the most significant antitumour effect, with a complete remission rate of 50% and prolonged survival. On day 14, tumour samples from non-responsive mice revealed insufficient recruitment of T cells as the reason for uncured tumours. Notably, mice cured with PTT + DC and PTT + DC + A treatments showed no detectable lung nodules. CONCLUSION This study demonstrated that the combination of PTT with DC-based immunotherapy and atezolizumab effectively overcomes the non-sensitive nature of CT26 tumours. These findings highlight the potential of this combination approach for colorectal cancer treatment.

Abstract
BACKGROUND Patients with heart failure (HF) and colorectal cancer (CRC) are prone to comorbidity, a high rate of readmission, and complex healthcare needs. Self-care for people with HF and CRC after hospitalisation can be challenging, and patients may leave the hospital unprepared to self-manage their disease at home. eHealth solutions may be a beneficial tool to engage patients in self-care. METHODS A randomised controlled trial with an embedded evaluation of intervention engagement and cost-effectiveness will be conducted to investigate the effect of eHealth intervention after hospital discharge on the self-efficacy of self-care. Eligible patients with HF or CRC will be recruited before discharge from two Norwegian university hospitals. The intervention group will use a nurse-assisted intervention-eHealth@Hospital-2-Home-for six weeks. The intervention includes remote monitoring of vital signs; patients' self-reports of symptoms, health and well-being; secure messaging between patients and hospital-based nurse navigators; and access to specific HF and CRC health-related information. The control group will receive routine care. Data collection will take place before the intervention (baseline), at the end of the intervention (Post-1), and at six months (Post-2). The primary outcome will be self-efficacy in self-care. The secondary outcomes will include measures of burden of treatment, health-related quality of life and 30- and 90-day readmissions. Sub-study analyses are planned in the HF patient population with primary outcomes of self-care behaviour and secondary outcomes of medication adherence, and readmission at 30 days, 90 days and 6 months. Patients' and nurse navigators' engagement and experiences with the eHealth intervention and cost-effectiveness will be investigated. Data will be analysed according to intention-to-treat principles. Qualitative data will be analysed using thematic analysis. DISCUSSION This protocol will examine the effects of the eHealth@ Hospital-2-Home intervention on self-care in two prevalent patient groups, HF and CRC. It will allow the exploration of a generic framework for an eHealth intervention after hospital discharge, which could be adapted to other patient groups, upscaled, and implemented into clinical practice.

This case report highlights a rare clinical scenario of a 46-year-old male presenting with constipation and fecaloid vomiting due to an impacted chicken bone within an unidentified rectosigmoid neoplasm, leading to acute malignant colonic obstruction. Emergent exploratory laparotomy revealed an impacted chicken bone lodged in a previously unknown rectosigmoid tumor. An anatomopathological examination revealed a mucinous adenocarcinoma with clear margins and one pericolic metastatic lymph node. The postoperative period was uneventful, and the patient was proposed for adjuvant chemotherapy. The abrupt onset of symptoms allowed for an early diagnosis, emphasizing the unexpected association between foreign body impaction and incidental malignant obstruction. This case underscores the complexity of managing foreign body ingestion in the gastrointestinal tract and emphasizes the crucial role of diagnostic imaging in surgical planning. Furthermore, it draws attention to the potential occurrence of colorectal cancer in younger individuals, emphasizing the necessity for clinical vigilance and screening strategies beyond conventional age recommendations.

Abstract
Large bowel obstruction is a serious event that occurs in approximately 25% of all intestinal obstructions. It is attributed to either benign, malignant, functional (pseudo-obstruction), or mechanical conditions. Benign etiologies of colonic obstructions include colon volvulus, anastomotic strictures, radiation injury, ischemia, inflammatory processes such as Crohn's disease, diverticulitis, bezoars, and intussusception.

Abstract
BACKGROUND Laparoscopic-assisted colorectal surgery is an effective surgery to treat colorectal cancer. During the laparoscopic-assisted colorectal surgery, a midline incision and several trocar insertions are required during the surgery. OBJECTIVE To observe whether the rectus sheath block based on the locations of the surgical incision and trocars can significantly reduce the pain score on the first day after surgery. DESIGN This study was a prospective, double-blinded, randomized controlled trial approved by the Ethics Committee of First Affiliated Hospital of Anhui Medical University (registration number: ChiCTR2100044684). SETTINGS All patients were recruited from 1 hospital. PATIENTS Forty-six patients aged 18 to 75 years undergoing elective laparoscopic-assisted colorectal surgery were successfully recruited, and 44 patients completed the trial. INTERVENTIONS Patients in the experimental group received rectus sheath block, with 0.4% ropivacaine 40 to 50 mL, whereas the control group received an equal volume of normal saline. MAIN OUTCOME MEASURES The primary outcome was pain score on postoperative day 1. Secondary outcomes included patient-controlled analgesia use at 24 and 48 hours after surgery and pain score at 6, 12, and 48 hours after surgery. RESULTS Pain scores at rest and during activity at 6, 12, 24, and 48 hours after surgery and patient-controlled analgesia consumption of patients on the first day after surgery were significantly lower in the experimental group than those in the control group (all p < 0.05). LIMITATIONS We did not separate pain into visceral and somatic pain because patients often had difficulty differentiating the source of pain. CONCLUSIONS Our research indicates that in the context of multimodal analgesia, the rectus sheath block according to the midline incision and the positions of the trocars can reduce the pain scores and consumption of analgesic drugs on the first day after surgery for patients undergoing laparoscopic-assisted colorectal surgery.

Abstract
The aim of this study was to evaluate the efficacy of endoscopic polypectomy as a therapeutic treatment for malignant alteration of colorectal polyps. In a 5-year research, 89 patients were included, who were tested and treated at the University Clinical Center Kragujevac, Kragujevac, Serbia, with the confirmed presence of malignant alteration polyps of the colon by colonoscopy, which were removed using the method of endoscopic polypectomy and confirmed by the histopathological examination of the entire polyp. After that, the same group of patients was monitored endoscopically within a certain period, controlling polypectomy locations and the occurrence of a possible remnant of the polyp, in the period of up to 2 years of polypectomy. We observed that, with an increasing size of polyps, there is also an increase in the percentage of the complexity of endoscopic resection and the appearance of remnant with histological characteristics of the invasive cancer. The highest percentage of incomplete endoscopic resection and the appearance of remnant with histological characteristics of the invasive cancer were shown at malignant altered polyps in the field of tubulovillous adenoma. Eighteen patients in total underwent the surgical intervention. In conclusion, our data support the high efficacy of endoscopic polypectomy for the removal of the altered malignant polyp.

Alternative Splicing Events and Their Clinical Significance in Colorectal Cancer: Targeted Therapeutic Opportunities. Cancers (Basel) 2023; 15:3999.

Abstract
Colorectal cancer (CRC) ranks as one of the top causes of cancer mortality worldwide and its incidence is on the rise, particularly in low-middle-income countries (LMICs). There are several factors that contribute to the development and progression of CRC. Alternative splicing (AS) was found to be one of the molecular mechanisms underlying the development and progression of CRC. With the advent of genome/transcriptome sequencing and large patient databases, the broad role of aberrant AS in cancer development and progression has become clear. AS affects cancer initiation, proliferation, invasion, and migration. These splicing changes activate oncogenes or deactivate tumor suppressor genes by producing altered amounts of normally functional or new proteins with different, even opposing, functions. Thus, identifying and characterizing CRC-specific alternative splicing events and variants might help in designing new therapeutic splicing disrupter drugs. CRC-specific splicing events can be used as diagnostic and prognostic biomarkers. In this review, alternatively spliced events and their role in CRC development will be discussed. The paper also reviews recent research on alternatively spliced events that might be exploited as prognostic, diagnostic, and targeted therapeutic indicators. Of particular interest is the targeting of protein arginine methyltransferase (PMRT) isoforms for the development of new treatments and diagnostic tools. The potential challenges and limitations in translating these discoveries into clinical practice will also be addressed.

Progress in the field of noninvasive diagnostics for colorectal cancer: a systematic review for the accuracy of blood-based biomarkers for detection of advanced pre-cancerous lesions. Expert Rev Mol Diagn 2023; 23:1233-1250.

Abstract
BACKGROUND Early detection of pre-cancerous adenomas through screening can reduce colorectal cancer (CRC) incidence. Fecal immunochemical tests are commonly used, but have limited sensitivity for pre-cancerous lesions. Blood-based screening may improve test sensitivity. This systematic review and meta-analysis was conducted to evaluate the accuracy of blood-based biomarkers for detection of advanced pre-cancerous lesions. RESEARCH DESIGN AND METHODS We present the accuracy of blood-based biomarkers for the detection of advanced pre-cancerous lesions. EMBASE, Web of Science and PubMed databases were searched, with study populations limited to adults diagnosed with advanced pre-cancerous lesions at colonoscopy, who had a blood-based biomarker test analyzed with reports of sensitivity and specificity. RESULTS 69 studies were identified, which assessed 133 unique biomarkers sets. The best performing test was a panel of 6 miRNAs, with a sensitivity of 95% and specificity of 90% for advanced pre-cancerous lesions. Only 6 biomarkers demonstrated sensitivity ≥ 50% and specificity ≥ 90% for the detection of advanced pre-cancerous lesions. CONCLUSION Many different blood-based biomarkers have been assessed for detection of advanced pre-cancerous lesions, but few have progressed beyond the discovery stage. While some biomarkers have reported high sensitivity and specificity, larger prospective studies in unbiased intended-use screening populations are required for validation.

Abstract
Aims The objective of this work is to evaluate the epidemiological profile of colorectal cancers, histologically proven over a 5-year period (2012-2016) in the Tlemcen region. Methods A retrospective study of 581 cases of colorectal cancer collected at the epidemiology department of the University Hospital Center (UHC) of Tlemcen between January 2012 and December 2016 was performed. Epidemiological data were processed using SPSS version 25 and Microsoft Excel 2010. Results The epidemiological profile has shown that colorectal cancer in our region ranks 3rd in both sexes. There were 322 men (55.4%) affected compared to 259 women (44.6%) with a sex ratio of 1.2. A predominance of males is noted in 50-60 age group, while for the female sex, the dominance is between 60-70 years old. The mean age of CRC occurrence was 60±13 years, with an extremity ranging from16 to 90. A significantly higher rate was recorded for rectal cancer (43.7%) followed by sigmoid colon (5.7%). Variable rates were recorded during the 5 years with a peak in 2014 (27.9%). Conclusion Regular analysis of these data, if supplemented with additional data on diagnostic modalities like circular RNA diagnostic, will contribute to the assessment of the impact over time of public policies on nationally organized CRC screening.

Abstract
As the backbone of oncological treatments, systemic chemotherapy is still one of the main pawns in cancer care, alone or in combination with newer targeted agents. All chemotherapy agents can be associated with a type of adverse event called an infusion reaction, which can be characterized as unpredictable, non-dose related, and unexplained by the cytotoxic profile of the drug. For some of these events, a certain immunological mechanism can be identified by blood or skin testing. In this case, we can speak of true hypersensitivity reactions that occur as a response to an antigen/allergen. The current work summarizes the main antineoplastic therapy agents and their susceptibility to induce hypersensitivity reactions and also includes a review of clinical presentation, diagnostic methods in hypersensitivity reactions, and perspectives to overcome these negative events in the treatment of patients suffering from various types of cancer.

Abstract
Hydrogel has been widely used in modern biotherapeutics due to its excellent biocompatibility, degradability, and high drug loading capacity. Among them, the construction of a phototherapy system including photosensitizer and hydrogel has aroused great interest in tumor therapy. Unfortunately, complex modifications are necessary to integrate different photosensitizers into the hydrogel. In this work, an injectable hydrogel was proposed by the Schiff base reaction between HA-CHO and carbon dots (CDs), which can realize PTT and PTT simultaneously. Notably, the CDs with rich -NH2 can be used not only as a photosensitizer but also as an efficient cross-linking agent for the Schiff base reaction to form a hydrogel network. The CD@Hydrogel with outstanding biosafety showed a high antitumor effect after 660 nm laser irradiation in in vitro and in vivo experiments. In summary, the CD@Hydrogel can not only realize PTT and PDT synergistic treatment under one light source but also act as a cross-linking agent to react with HA-CHO to form hydrogel, which is simple and efficient, providing a new strategy for cancer phototherapy.

Abstract
Serum uric acid (SUA) may play an important role in the occurrence of colorectal cancer (CRC). This study aims to explore the association of SUA with the risk of CRC incidence by drawing data from the Kailuan Study. We prospectively examined the association between SUA and risk of CRC incidence among 93,356 Chinese. Eligible participants were divided into three groups based on their tertiles of SUA. Cox proportional hazards regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (95% CIs) of CRC. During a median follow-up of 13.02 years, 583 new-onset CRC cases were identified. After adjustments were made for confounders, participants in the highest tertiles of SUA exhibited a 1.55-fold increased risk of CRC compared with patients with the lowest SUA levels (HRT3 vs. T1 = 1.55, 95% CI: 1.09-2.30). The associations of SUA with the risk of CRC were slightly reduced but remained substantial in the competing risk analyses when treating CRC unrelated death as the competing risk event. This study found a positive association of SUA with CRC incidence. Specific prevention efforts could be focused on the population with higher levels of SUA.

Høydahl Ø, Edna TH, Xanthoulis A, Lydersen S, Endreseth BH. The impact of age on rectal cancer treatment, complications and survival. BMC Cancer 2022; 22:975. [PMID: 36096818 PMCID: PMC9465957 DOI: 10.1186/s12885-022-10058-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 09/05/2022] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND The number of older patients with rectal cancer is increasing. Treatment outcome discrepancies persist, despite similar treatment guidelines. To offer the oldest patients optimal individually adjusted care, further knowledge is needed regarding treatment strategy and outcome. The present study aimed to evaluate treatment, postoperative complications, and survival in older patients treated for rectal cancer. METHODS This retrospective study included all 666 patients (n=255 females, n=411 males) treated for rectal cancer at Levanger Hospital during 1980-2016 (n=193 <65 years, n=329 65-79 years, n=144 ≥80 years). We performed logistic regression to analyse associations between complications, 90-day mortality, and explanatory variables. We performed a relative survival analysis to identify factors associated with short- and long-term survival. RESULTS Despite a similar distribution of cancer stages across age-groups, patients aged ≥80 years were treated with a non-curative approach more frequently than younger age groups. Among patients aged ≥80 years, 42% underwent a non-curative treatment approach, compared to 25% of patients aged <65 years, and 25% of patients aged 65-79 years. The 90-day mortality was 15.3% among patients aged ≥80 years, compared to 5.7% among patients aged <65 years, and 9.4% among patients aged 65-79 years. Among 431 (65%) patients treated with a major resection with curative intent, the 90-day mortality was 5.9% among patients aged ≥80 years (n=68), compared to 0.8% among patients aged <65 years (n=126), and 3.8% among patients aged 65-79 years (n=237). The rate of postoperative complications was 47.6%. Pneumonia was the only complication that occurred more frequently in the older patient group. The severity of complications increased with three factors: age, American Society of Anaesthesiologists score, and >400 ml perioperative blood loss. Among patients that survived the first 90 days, the relative long-term survival rates, five-year local recurrence rates, and metastases rates were independent of age. CONCLUSION Patients aged ≥80 years were less likely to undergo a major resection with curative intent and experienced more severe complications after surgery than patients aged <80 years. When patients aged ≥80 years were treated with a major resection with curative intent, the long-term survival rate was comparable to that of younger patients.

Abstract
BACKGROUND To compare clinical and survival outcomes between laparoscopic versus open surgery in elderly colorectal cancer patients. METHODS PubMed, Embase and Scopus databases were systematically searched. The review included studies that were either randomized controlled trials (RCTs) or observational in design. STATA was used for statistical analysis. RESULTS The meta-analysis was conducted with 24 studies. Compared with elderly subjects with open surgery, those undergoing laparoscopic surgery had a lower risk of mortality (within 3 months postoperatively) (RR 0.70, 95% CI: 0.53, 0.94). The long-term overall survival (HR 0.96, 95% CI: 0.89, 1.04), disease-free survival (HR 1.02, 95% CI: 0.93, 1.13), risk of recurrence (RR 1.44, 95% CI: 0.90, 2.30) and readmission (RR 1.11, 95% CI: 0.88, 1.40) rates were statistically similar in both the groups. The operative time (in minutes) was higher (WMD 30.37, 95% CI: 17.75, 43.0) and the blood loss (in ml) was lower (WMD -78.85, 95% CI: -101.96, -55.75) in those undergoing laparoscopic surgery. The length of hospital stay (in days) (WMD -2.53, 95% CI: -3.11, -1.95) and the time of return of bowel movements (in days) (WMD -1.06, 95% CI: -1.20, -0.93) was lower in those with laparoscopic surgery. The pooled risk of complications was lower in those with laparoscopic surgery (RR 0.66, 95% CI: 0.60, 0.74), compared with open surgery. CONCLUSIONS Findings suggest that in elderly subjects with colorectal cancer, laparoscopic surgery appears to be more beneficial than open surgery and should be prioritized, subject to the availability of required technical skills and facilities.

Abstract
Colorectal cancer (CRC) is an important public health problem, especially in Europe. Every year approximately 435,000 new cases are being diagnosed with colorectal cancer. Half of these people die, which makes this type of cancer a second-rated mortality cause in Europe. The main aim of this paper was to make a literature search related to colorectal cancer with a focus on the developed Western European countries and countries close to the Republic of North Macedonia.
This paper also intended to provide a picture of the early screening for colorectal cancer as the most efficient method for prevention and early detection of colorectal cancer and its application in some developed countries. For achieving the objectives set out in this paper, a survey of the available literature (both electronic and print) as well as of the grey literature was made. A systematic search of the following databases was made: PubMed, European Commission, and Google Scholar. The inclusion criteria were studies conducted between 2008 and 2020, with an emphasis on the newest studies and those published in the neighboring countries. According to the WHO recommendations and practices in modern countries, colorectal cancer should be identified as a serious public health problem. This includes unclear cause of its occurrence, as well as all possible risk factors which make it almost possible to implement an adequate prevention program.
The most acceptable sensitive test for implementation of the screening program for colorectal cancer is the utilization of the FOB test. It is of great importance to follow-up patients with a positive FOB test as well as to offer easy access to health services, i.e., screening program to the population.

Neutrophil infiltration combined with necrosis in the primary tumor is a useful prognostic indicator for three‑year disease‑free survival time in patients with colorectal cancer. Oncol Lett 2022; 23:199. [PMID: 35572490 PMCID: PMC9100607 DOI: 10.3892/ol.2022.13320] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 01/11/2022] [Indexed: 11/30/2022] Open
Abstract
Histopathological evaluation plays a key role in the diagnosis of colorectal cancer (CRC). Tumor-related local inflammation is regarded as a novel prognostic parameter. Neutrophils constitute one of the main types of inflammatory cells. The aim of the present study was to evaluate the prognostic value of intratumoral tumor-associated neutrophils (intraTANs), stromal TANs (stromaTANs) and necrosis, as well as their combined parametric value in formalin-fixed paraffin-embedded tissue sections from patients with CRC. For this purpose, a retrospective study of 160 patients with CRC who underwent surgery was conducted. The association of intraTANs, stromaTANs, necrosis and their combined parametric value with the clinicopathological features of patients with CRC was examined. The Kaplan-Meier method and the log-rank test were used to compare survival curves. To identify independent prognostic factors, uni- and multivariate Cox proportional hazards regression models were used. StromaTANs were associated with lymph node metastasis (P=0.049) and tumor deposits (P=0.041). In addition, necrosis was found to be associated with venous (P=0.003), lymphatic (P=0.007) and perineural (P=0.015) invasion, as well as with lymph node metastasis (P=0.033), the number of invaded lymph nodes (P=0.012), and lymph node pouch invasion (P=0.043). Furthermore, necrosis was found to be associated with the white blood cell count (P=0.030), neutrophil count (P=0.011), the combined neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (NLR-PLR) (P=0.038), and the combined platelet and NLR (PLT-NLR status) (P=0.030), as well as with the serum carcinoembryonic antigen (CEA) levels following surgery (P=0.011) and the monocyte-to-lymphocyte ratio (P=0.023). The combined parametric value was found to be associated with pT stage (P=0.049), venous (P=0.034) and lymphatic (P=0.026) invasion, and with serum CEA levels prior to surgery (P=0.029). The analysis of the 3-year disease-free survival (DFS) time revealed that tumor growth [hazard ratio (HR), 2.070; 95% CI, 1.837-3.808; P=0.003] and the combined parametric value (intraTANs, stromaTANs and necrosis, HR, 1.577; 95% CI, 1.372-3.032; P=0.028) were independent factors for patients with CRC. Taken together, the findings of the present study demonstrated that the combined value of neutrophils and necrosis examined in the cancerous tissue may be used as a prognostic factor for the 3-year DFS time in patients with CRC.

Abstract
Background Few studies have addressed colon cancer surgery outcomes in an unselected cohort of octogenarian patients. The present study aimed to evaluate the relative survival of octogenarian patients after a major resection of colon cancer with a curative intent. Methods All patients diagnosed with colon cancer at Levanger Hospital between 1980 and 2016 were included. We performed logistic regression to test for associations between 90-day mortality and explanatory variables. We performed a relative survival analysis to identify factors associated with short- and long-term survival. Results Among 237 octogenarian patients treated with major resections with curative intent, the 90-day mortality was 9.3%. Among 215 patients that survived the first 90 days, the 5 year relative survival rate was 98.7%. The 90-day mortality of octogenarian patients was significantly higher than that of younger patients, but the long-term survival converged with that of younger patients. Among octogenarian patients, the incidence of colon cancer more than doubled during our 37-year observation period. The relative increase in patients undergoing surgery exceeded the increase in incidence; hence, more patients were selected for surgery over time. A high 90-day mortality was associated with older age, a high American Society of Anaesthesiologists (ASA) score, and emergency surgery. Moreover, worse long-term survival was associated with a high Charlson Comorbidity Index, a high ASA score, a worse TNM stage, emergency surgery and residual tumours. Both the 90-day and long-term survival rates improved over time. Conclusion Among octogenarian patients with colon cancer that underwent major resections with curative intent, the 90-day mortality was high, but after surviving 90 days, the relative long-term survival rate was comparable to that of younger patients. Further improvements in survival will primarily require measures to reduce the 90-day mortality risk.

Abstract
PURPOSE Colorectal cancer (CRC) affects many older adults. We investigated the efficacy and safety of adding anti-epidermal growth factor receptor (EGFR) agents to doublet chemotherapy (DC) in older patients. METHODS Patients with RAS wild-type (WT) metastatic CRC (mCRC) receiving first-line DC + anti-EGFR (n = 1191) or DC alone (n = 729) from seven trials in the Aide de Recherche en Cancerologie Digestive database were included. The prognostic and predictive effects of age were investigated. Progression-free and overall survival (OS) were evaluated between age groups (≥70 vs <70) for DC + anti-EGFR. In addition, outcomes were compared between DC+/-anti-EGFR within age groups in three trials with a DC alone arm. Subsequently, the same analysis was conducted for left-sided tumours. Adverse events grade ≥3 (G3+) were compared between age groups. RESULTS Older (vs younger) patients receiving DC + anti-EGFR had similar progression-free survival (PFS) (8.7 vs 10.3 months; hazard ratio (HR) = 1.20 [0.96-1.49];p = 0.107) but inferior OS (21.3 vs 26.3; HR = 1.36 [1.08-1.72];p = 0.011). DC + anti-EGFR (vs DC alone) improved OS (23.9 vs 20.3; HR = 0.82 [0.70-0.95];p = 0.008) and PFS (11.2 vs 8.9; HR = 0.70 [0.60-0.82];p < 0.001) in younger but not older patients: OS (24.7 vs 17.6; HR [95% confidence interval {CI}] = 0.77 [0.58-1.04];p = 0.092) and PFS (9.1 vs 8.7; HR [95% CI] = 0.85[0.63-1.15];p = 0.287). In left-sided 'only' tumours, the following outcomes for older (vs younger) patients were observed. For DC + anti-EGFR, PFS 9 versus 11.2 months; HR1.10 (95% CI 0.83-1.46); p = 0.52, OS 25.6 vs 30.3 HR 1.32 (95% CI 0.97-1.79), p = 0.086. For DC + anti-EGFR (vs DC alone), PFS and OS for younger patients were 11.9 vs 9.2 months HR 0.60 (95% CI 0.47-0.78) p < 0.001 and 24.1 versus 23.3 months HR 0.84 (95% CI 0.67-1.04), respectively. For older patients, PFS and OS were 13.1 versus 8.5 months, HR 0.51 (95% CI, 0.28-0.93), P = 0.027 and 26.3 versus 16.5 months HR 0.49 (95% CI, 0.28-0.85), respectively. There was no significant difference in toxicity among different age groups. CONCLUSIONS Older (vs younger) patients with mCRC RAS WT patients had comparable toxicity and efficacy with the addition of anti-EGFR agents to chemotherapy.

Nano-Delivery of a Novel Inhibitor of Polynucleotide Kinase/Phosphatase (PNKP) for Targeted Sensitization of Colorectal Cancer to Radiation-Induced DNA Damage. Front Oncol 2022; 11:772920. [PMID: 35004293 PMCID: PMC8733593 DOI: 10.3389/fonc.2021.772920] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 11/24/2021] [Indexed: 12/29/2022] Open
Abstract
Inhibition of the DNA repair enzyme polynucleotide kinase/phosphatase (PNKP) increases the sensitivity of cancer cells to DNA damage by ionizing radiation (IR). We have developed a novel inhibitor of PNKP, i.e., A83B4C63, as a potential radio-sensitizer for the treatment of solid tumors. Systemic delivery of A83B4C63, however, may sensitize both cancer and normal cells to DNA damaging therapeutics. Preferential delivery of A83B4C63 to solid tumors by nanoparticles (NP) was proposed to reduce potential side effects of this PNKP inhibitor to normal tissue, particularly when combined with DNA damaging therapies. Here, we investigated the radio-sensitizing activity of A83B4C63 encapsulated in NPs (NP/A83) based on methoxy poly(ethylene oxide)-b-poly(α-benzyl carboxylate-ε-caprolactone) (mPEO-b-PBCL) or solubilized with the aid of Cremophor EL: Ethanol (CE/A83) in human HCT116 colorectal cancer (CRC) models. Levels of γ-H2AX were measured and the biodistribution of CE/A83 and NP/A83 administered intravenously was determined in subcutaneous HCT116 CRC xenografts. The radio-sensitization effect of A83B4C63 was measured following fractionated tumor irradiation using an image-guided Small Animal Radiation Research Platform (SARRP), with 24 h pre-administration of CE/A83 and NP/A83 to Luc+/HCT116 bearing mice. Therapeutic effects were analyzed by monitoring tumor growth and functional imaging using Positron Emission Tomography (PET) and [18F]-fluoro-3’-deoxy-3’-L:-fluorothymidine ([18F]FLT) as a radiotracer for cell proliferation. The results showed an increased persistence of DNA damage in cells treated with a combination of CE/A83 or NP/A83 and IR compared to those only exposed to IR. Significantly higher tumor growth delay in mice treated with a combination of IR and NP/A83 than those treated with IR plus CE/A83 was observed. [18F]FLT PET displayed significant functional changes for tumor proliferation for the drug-loaded NP. This observation was attributed to the higher A83B4C63 levels in the tumors for NP/A83-treated mice compared to those treated with CE/A83. Overall, the results demonstrated a potential for A83B4C63-loaded NP as a novel radio-sensitizer for the treatment of CRC.

Unveiling the tumour-regulatory roles of miR-1275 in cancer. Pathol Res Pract 2021; 230:153745.

Abstract
The rapid development of small RNA and molecular biology research in the past 20 years has enabled scientists to discover many new miRNAs that are proven to play essential roles in regulating the development of different cancer types. Among these miRNAs, miR-1275 is one of the well-studied miRNAs that has been described to act as a tumour-promoting or tumour-suppressing miRNA in various cancer types. Even though miR-1275 has been widely reported in different original research articles on its roles in modulating the progression of different cancer types, however, there is scarce an in-depth review that could constructively summarize the findings from different studies on the regulatory roles of miR-1275 in different cancer types. To fill up this literature gap, therefore, this review was aimed to provide an overview and summary of the roles of miR-1275 in modulating the development of different cancers and to unravel the mechanism of how miR-1275 regulates cancer progression. Based on the findings summarized from various sources, it was found that miR-1275 plays a vital role in regulating various cellular signaling pathways like the PI3K/AKT, ERK/JNK, MAPK, and Wnt signaling pathways, and the dysregulation of this miRNA has been shown to contribute to the development of multiple cancer types such as cancers of the liver, breast, lung, gastrointestinal tract and genitourinary tract. Therefore, miR-1275 has great potential to be employed as a biomarker to diagnose cancer and to predict the prognosis of cancer patients. In addition, by inhibiting the expression of its unique downstream targets that are involved in regulating the mentioned cellular pathways, this miRNA could also be utilized as a novel therapeutic agent to halt cancer development.

Yoo RN, Cho HM, Kye BH. Management of obstructive colon cancer: Current status, obstacles, and future directions. World J Gastrointest Oncol 2021; 13:1850-1862. [PMID: 35070029 PMCID: PMC8713324 DOI: 10.4251/wjgo.v13.i12.1850] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2021] [Revised: 07/07/2021] [Accepted: 09/23/2021] [Indexed: 02/06/2023] Open
Abstract
Approximately 10%–18% of patients with colon cancer present with obstruction at the initial diagnosis. Despite active screening efforts, the incidence of obstructive colon cancer remains stable. Traditionally, emergency surgery has been indicated to treat patients with obstructive colon cancer. However, compared to patients undergoing elective surgery, the morbidity and mortality rates of patients requiring emergency surgery for obstructive colon cancer are high. With the advancement of colonoscopic techniques and equipment, a self-expandable metal stent (SEMS) was introduced to relieve obstructive symptoms, allowing the patient’s general condition to be restored and for them undergo elective surgery. As the use of SEMS placement is growing, controversies about its application in potentially curable diseases have been raised. In this review, the short- and long-term outcomes of different treatment strategies, particularly emergency surgery vs SEMS placement followed by elective surgery in resectable, locally advanced obstructive colon cancer, are described based on the location of the obstructive cancer lesion. Controversies regarding each treatment strategy are discussed. To overcome current obstacles, a potential diagnostic method using circulating tumor DNA and further research directions incorporating neoadjuvant chemotherapy are introduced.

Abstract
PURPOSE OF REVIEW Improving outcomes for patients with colorectal cancer in both the adjuvant and metastatic setting has been challenging. Here, we review the current and future directions for using ctDNA in clinical practice. RECENT FINDINGS Circulating tumour DNA (ctDNA) with its ability to detect minimal residual disease is beginning to refine the way we assess recurrence risk in the adjuvant setting. We can potentially tailor treatments to reduce recurrence risk and minimize treatment toxicity. In the metastatic setting, ctDNA can provide a less invasive method of detecting clinically important genetic changes to guide molecularly targeted treatment and to identify mechanisms of molecular resistance. ctDNA can be a surrogate marker for treatment response and help guide the timing of anti-EGFR rechallenge. We await the results of the randomized clinical trials assessing clinical utility of ctDNA in both the adjuvant and metastatic setting before incorporating ctDNA into clinical practice.

Hypocalcemia: A possible risk factor for anastomotic leak in digestive surgery. Exp Ther Med 2021; 21:523. [PMID: 33815596 PMCID: PMC8014963 DOI: 10.3892/etm.2021.9955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 01/18/2021] [Indexed: 11/22/2022] Open
Abstract
Anastomotic leaks (ALs) remain the most severe complication in digestive surgery, as well as the most consumptive in terms of human and financial resources. There is an abundance of international research which has focused on identifying and correcting risk factors, and on individualized surgical management as well. The most frequent risk factors are male sex, obesity, diabetes, advanced malignant disease, ASA score, perioperative blood loss or perioperative transfusion, long operation time, emergency operation and altered nutritional status. The aim of the present study was to measure the preoperative serum calcium level and to find a possible correlation between calcium levels and the risk of AL occurrence. A retrospective analysis of medical records for 122 patients who underwent surgical gut resection with anastomosis for different pathologies was carried out. Preoperative serum calcium level and the occurrence of AL was noted. The results revealed that the average value of total blood calcium was 8.78 mg/dl, without a significant difference in sex groups. Hypocalcemia was identified in 44 patients (36.1%). AL was identified in 8 patients (6.6%), with a statistically insignificant difference between male and female patients. The average value of blood calcium in the AL patient group was 8.07 mg/dl, while in patients without AL the average value was 8.83 mg/dl. Hypocalcemia, defined as a serum calcium level below 8.5 mg/dl, was observed in 7 of the 8 patients presenting with AL (87.5%) and 37 patients who did not present with AL (32.5%), a significant difference with which to consider and include hypocalcemia in the group of risk factors for AL (P=0.001). In conclusion, preoperative low serum calcium level can represent a risk factor for AL in digestive surgery.
