The present study aimed to investigate in-depth a cytotoxic novel benzofuran-isatin conjugate (5a, 3-methyl-N'-(2-oxoindolin-3-ylidene)benzofuran-2-carbohydrazide) with promising potential anticancer activities in colorectal adenocarcinoma HT29 and metastatic colorectal cancer (CRC) SW620 cell lines. Thus, the primary cell events involved in tumorigenicity, tumor development, metastasis, and chemotherapy response were explored. Both CRC cell lines were exposed to different concentrations of Compound 5a and then subjected to real-time cell viability, migration, and invasion assays, colony formation and cytotoxicity assays, and flow cytometry for cell cycle analysis and apoptosis determination. Western blot and RT-qPCR were performed to assess the protein and transcript expression levels of epithelial-mesenchymal transition (EMT), cell cycle, and apoptosis markers. We showed that the Compound 5a treatment exhibited anticancer effects through inhibition of HT29 and SW620 cell viability, migration, and invasion, in a dose-dependent manner, which were associated with the upregulation of the tumor suppressor p53. Compound 5a also inhibited the colony formation ability of HT29 and SW620 cells and reversed EMT markers E-cadherin and N-cadherin expression. CRC cell exposure to Compound 5a resulted in a cell cycle arrest at the G1/G0 phase in HT29 cells and at the G2/M phase in SW620 cells, along with the downregulation of cyclin A1 expression, described to be involved in the S phase entry. Furthermore, Compound 5a-induced apoptosis was associated with the downregulation of the anti-apoptotic Bcl-xl marker, upregulation of pro-apoptotic Bax and cytochrome c markers, and increased mitochondrial outer membrane permeability, suggesting the involvement of mitochondria-dependent apoptosis pathway. In addition, the combination studies of Compound 5a with the main conventional chemotherapeutic drugs 5-fluorouracil, irinotecan, and oxaliplatin showed a more potent cytotoxic effect in both CRC cells than a single treatment. In conclusion, our findings described the interesting in vitro anticancer properties of Compound 5a, shown to have possible antitumor, antimetastatic, and pro-apoptotic activities, with the enhancement of the cytotoxic efficiency of conventional chemotherapeutic drugs. In vivo studies are requested to confirm the promising anticancer potential of Compound 5a for CRC therapy.

Abstract Background: In this study, we aimed to identify the oncological outcomes in colon cancer patients who underwent elective versus emergency curative resection. Methods: All patients who underwent curative resection for colon cancer between July 2015 and December 2019 were retrospectively reviewed and analyzed. Patients were divided into two groups based on the presentation into elective and emergency groups. Results: A total of 215 patients with colon cancer were admitted and underwent curative surgical resection. Of those, 145 patients (67.4%) were elective cases, and 70 (32.5%) were emergency cases. Family history of malignancy was positive in 44 patients (20.5%) and significantly more common in the emergency group (P = 0.016). The emergency group had higher T and TNM stages (P = 0.001). The 3-year survival rate was 60.9% and significantly less in the emergency group (P = 0.026). The mean duration from surgery to recurrence, 3-year disease-free survival, and overall survival were 1.19, 2.81, and 3.11, respectively. Conclusion: Elective group was associated with better 3-year survival, longer overall, and 3-year disease-free survival compared to the emergency group. The disease recurrence rate was comparable in both groups, mainly in the first two years after curative resection.

Colorectal cancer is a significant health concern in Saudi Arabia, ranking among the most common cancers and often presenting at advanced stages due to low early detection rates. Despite available screening tools, many cases are diagnosed late, leading to poor outcomes. The importance of early detection through screening cannot be overstated as it significantly improves prognosis and reduces mortality. This study was conducted as a cross-sectional survey in Riyadh from January to July 2024. It aimed to assess awareness and barriers to colorectal cancer screening among the general public. A self-administered questionnaire was distributed, yielding 768 eligible responses after applying exclusion criteria. The results revealed that, while 88% of respondents were aware of colorectal cancer, only 16% had undergone screening tests primarily via colonoscopy. Significant barriers to screening included a lack of physician recommendation, absence of a comprehensive national screening program and fear of complications from colonoscopy. Females were more likely to experience embarrassment and fair of pain as barriers compared to males. Additionally, residents of rural areas faced challenges related to the avalanche of screening facilities. These findings underscore the need for targeted public health interventions, including enhanced awareness campaigns and the development of a national CRC screening program to increase early detection rates and reduce the burden of colorectal cancer in Saudi Arabia.

Background: Crohn's disease (CD) is associated with malnutrition, an independent risk factor for surgical morbidity and mortality in more than 65% of patients, with a significant impact on disease outcomes. In this single-center retrospective cohort study, we aimed to investigate the impact of total parenteral nutrition (TPN) on the surgical outcomes of patients with CD. Methods: This study included patients with CD who underwent abdominal surgery. We compared patients who received preoperative total parenteral nutrition (TPN group) to those who did not (non-TPN group). Prolonged oral intolerance, albumin level <30 g/L, and body mass index <18.5 were the main indications for TPN. We evaluated postoperative surgical complications in both groups. Results: Between January 2010 and October 2018, 169 eligible patients underwent abdominal surgery. The TPN and non-TPN groups included 40 and 129 patients, respectively. The mean albumin level was significantly lower in the TPN group (P = 0.013). Laparoscopic surgery was performed in 76.9% of the patients, with a conversion rate of 11.6%. Infectious and non-infectious complications developed in 8.9% and 16% of patients, respectively. Surgical complications were comparable between the groups (P >0.05). Conclusions: Despite oral intake intolerance and severe disease in the TPN group, the surgical complications were comparable between the groups.

Background Malignant colonic obstruction (MCO) occurs in 10–18% of colorectal cancers. Traditionally, emergency surgery has been the standard treatment modality. However, it is associated with higher morbidity and mortality rates compared to patients undergoing elective surgery. With the advancement of endoscopic techniques, the self-expandable metal stent has been advocated as an alternative management that provides relief of obstructive symptoms, allowing the patient’s general condition to be restored and enabling elective surgery. Furthermore, the ability to complete staging allowed identification and avoidance of unnecessary surgery in patients with advanced disease who need palliative measures. However, various stent-related complications have been reported in the literature, including perforation, migration, and obstruction. In this study, we aimed to evaluate the success and complication rates of stent placement in MCO and compare short-term outcomes to those of upfront surgical management. Methods We conducted a retrospective cohort study that included all patients with MCO between March 2015 and September 2021. Patients who had colon perforation at the time of the diagnosis, benign colonic obstruction, tumors of the rectum, or peritoneal metastasis that underwent cytoreductive surgery were all excluded. Patients were divided into groups according to the initial treatment, stent versus surgery, and the intent of therapy, curative versus palliative. Data was collected from medical records. Results Among 112 patients, 24 had stenting as a bridge to surgery (SBTS), and 16 underwent palliative stenting. The technical success rate was 95%, with failure in two patients due to complete obstruction and perforation in one patient each. Two patients (5%) who underwent stenting had clinical failure with persistent symptomatic obstruction beyond 48 h. The early complication rate following stent insertion was 8%, primarily due to perforation, obstruction from fecal impaction, and stent kinking. SBTS did not affect the laparoscopic approach or stoma creation rate among curative patients. However, it was associated with a more extended hospital stay. Half the patients who received stenting in the palliative group required re-stenting due to re-obstruction, with a mean stent patency time of 7 months. Conclusions Management of MCO varies based on the patient’s clinical presentation, tumor site, and surgeon’s preference. Stent placement, whether as a bridge to surgery or as a palliative measure, is a safe, less invasive, and effective management option with success and low complication rates.

Background A considerable number of patients with colon cancer present with a colonic obstruction. The use of self-expanding metallic stents (SEMS) as a bridge to surgery (BTS) in potential curative patients with left-sided colonic cancer obstruction remains debatable. Therefore, this study aimed to investigate the 5-year oncological outcomes of using a SEMS as a BTS. Methods All patients with left-sided malignant colon obstruction who underwent curative surgery with no metastasis upon presentation between March 2009 and May 2013 were retrospectively reviewed and analyzed. Results A total of 45 patients were included, 28 patients underwent upfront surgery, and 17 patients had a stent as a bridge to surgery. T4 stage was statistically significantly higher in patients who had a SEMS as a BTS (35.3% vs. 10.7%) (p-value 0.043) . The mean duration in days of the SEMS to surgery was 13.76 (SD 10.08). TNM stage 3 was a prognostic factor toward distant metastasis (HR 5.05). When comparing patients who had upfront surgery to those who had a SEMS as a BTS, higher 5-year disease-free survival (75% vs. 72%) and 5-year overall survival (89% vs. 82%) were seen in patients who had upfront surgery. However, both were statistically insignificant. Conclusion Using self-expanding metallic stents as a bridge to surgery yields comparable 5-year survival and disease-free survival rates to upfront emergency surgery. The decision to use SEMS versus opting for emergency surgery should be made after careful patient selection and with the assistance of experienced endoscopists. Trial registration N/A.

Background and Objectives: Colorectal cancer (CRC) remains a major global health issue. Although chemotherapy is the first-line treatment, its effectiveness is limited due to drug resistance developed in CRC. To overcome resistance and improve the prognosis of CRC patients, investigating new therapeutic approaches is necessary. Materials and Methods: Using human colorectal adenocarcinoma (HT29) and metastatic CRC (SW620) cell lines, the potential anticancer properties of a newly synthesized compound 1-(Isobutyl)-3-(4-methylbenzyl) benzimidazolium chloride (IMBZC) were evaluated by performing MTT cytotoxicity, cell migration, and colony formation assays, as well as by monitoring apoptosis-related protein and gene expression using Western blot and reverse transcription–quantitative polymerase chain reaction technologies. Results: Tested at various concentrations, the half-maximal inhibitory concentrations (IC50) of IMBZC on HT29 and SW620 cell growth were determined to be 22.13 µM (6.97 μg/mL) and 15.53 µM (4.89 μg/mL), respectively. IMBZC did not alter the cell growth of normal HEK293 cell lines. In addition, IMBZC inhibited cell migration and significantly decreased colony formation, suggesting its promising role in suppressing cancer metastasis. Mechanistic analyses revealed that IMBZC treatment increased the expression of pro-apoptotic proteins p53 and Bax, while decreasing the expression of anti-apoptotic proteins Bcl-2 and Bcl-xL, thus indicating the induction of apoptosis in IMBZC-treated CRC cells, compared to untreated cells. Additionally, the addition of IMBZC to conventional chemotherapeutic drugs (i.e., 5-fluorouracil, irinotecan, and oxaliplatin) resulted in an increase in the cytotoxic potential of the drugs. Conclusions: This study suggests that IMBZC has substantial anticancer effects against CRC cells through its ability to induce apoptosis, inhibit cancer cell migration and colony formation, and enhance the cytotoxic effects of conventional chemotherapeutic drugs. These findings indicate that IMBZC could be a promising chemotherapeutic drug for the treatment of CRC. Further research should be conducted using in vivo models to confirm the anti-CRC activities of IMBZC.

BackgroundFamilial adenomatous polyposis (FAP) syndrome has a near-100% lifetime risk of colorectal cancer. Early surveillance and prophylactic surgery have been advocated to reduce this risk. However, the surveillance practices among FAP individuals in Saudi Arabia are unknown. We aimed to explore surveillance compliance in our population, as well as the disease impact on their quality of life (QoL).MethodsAll patients with FAP who underwent surgical resection at King Saud University Medical City between 2016 and 2022 were included. Demographic data, clinical features, family history, and compliance with surveillance were collected and analyzed. QoL questionnaires: Short-form health survey (SF-36) and European Organization for Research and Treatment (EORTC) were conducted by phone interview.ResultsA total of 14 patients were included with an average age of 25 years. Three patients (21.4%) were the first of their family members to develop FAP. Nine patients (64%) were untested for genetic mutation due to lack of referral to geneticists. The compliance rate toward both pre-operative colonoscopy and upper endoscopy were 78%. However, 38% and 27% compliance rates were observed toward initial and post-operative colonoscopy, respectively. The compliance rate was 14% toward thyroid ultrasound. QoL scores varied among patients, with a mean score above 60 across all SF-36 domains.ConclusionAn overall poor compliance was observed among our participants, particularly toward thyroid ultrasound. Increased health awareness and patient education are essential. In addition, the importance of surveillance and genetic counseling should be emphasized among physicians treating these patients.

Bariatric surgery provides an effective option for the management of morbid obesity. Several studies have investigated the association between bariatric surgery and secondary hyperparathyroidism (SHPT). This study aims to compare the levels of blood biomarkers, specifically, calcium (Ca), vitamin D, and phosphate (PO4), and their association with parathyroid hormone (PTH) levels pre- and post-bariatric surgery. In addition, it aims to assess the prevalence of hyperparathyroidism post-bariatric surgery in a tertiary care hospital in Saudi Arabia. A prospective cohort study was conducted at a large tertiary care hospital between May 2017 and April 2019. The study included adult obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Patients were excluded if they were known to have any comorbidities, receiving vitamin supplements, and those who had undergone bariatric procedures previously. Routine blood tests, including PTH, vitamin D, Ca, and PO4, were collected at baseline, and post-surgery. A total of 143 patients who underwent LSG were included in the study. Hyperparathyroidism was observed in 15.4% of patients at baseline and in 36.4% of patients' post-surgery (p < 0.001). Low vitamin D levels, which were highly prevalent before surgery, decreased sustainably (66.4% pre-operative and 28% at follow-up after surgery, P=0.032). Baseline hypocalcemia was observed in 20.3% of patients compared to 8.4% post-surgery (P=0.546). Hypophosphatemia was present in 60.8% of subjects at baseline, while the percentage dropped to 21.7% post-surgery. There was a significant association between PO4 and PTH levels at baseline. Post-operatively, there was a significant correlation between PTH and both vitamin D and calcium levels. Our study showed that the higher levels of PTH post LSG can be related to vitamin D deficiency and lower calcium levels, despite patients following the provided recommendations for supplementation. This study also emphasizes the importance of routine testing for hyperparathyroidism both before and after bariatric surgery.

Cholecystocolonic fistula (CCF) and hemorrhagic cholecystitis are rare complications of gallstones that have a wide range of non-specific symptoms and clinical severity. We present a case of a 74-year-old woman on warfarin who presented to the emergency department with a 10-day history of abdominal pain, vomiting, and watery diarrhea. Her abdomen was distended with generalized tenderness and palpable mass in the right lower quadrant. Laboratory tests revealed leukocytosis and an elevated international normalized ratio (INR). After admission and imaging, exploratory laparotomy showed hemorrhagic cholecystitis with CCF in the cecum. There was no pus or stool contamination. A cholecystectomy followed by right hemicolectomy with primary ileocolic anastomosis was performed. The postoperative course was uneventful, and the patient was discharged in stable condition. The presence of hemorrhagic cholecystitis in conjunction with CCF could lead to significant consequences such as hemorrhagic and septic shock in older patients with comorbidities. It is crucial to identify and intervene early before clinical deterioration.
