    Abstract Background: Recently, there has been an increase in the incidence of colorectal cancer in Saudi Arabia. Although numerous studies worldwide have investigated the economic burden of colorectal cancer the information specific to Saudi Arabia remains limited. While advanced cancer treatments offer substantial benefits, they they also come with substantial financial challenges.
    Objective: This study aimed to estimate the economic burden of colorectal cancer and identify the primary cost drivers.
    Method: This retrospective, single-center cost of illness study examined all patients with colorectal cancer from January 2017 to December 2020. This study used a micro-costing, bottom-up approach to estimate healthcare resource utilization and direct medical costs associated with colorectal cancer.
    Result: The study included 326 patients with colorectal cancer. The total direct medical cost for all patients were $19 million, with an annual cost per patient of $58,384. Medication costs were the primary driver of healthcare spending (45%) of the total cost, followed by surgical costs (27%). This study explained cost associated with colorectal cancer, which represents a significant cost to the Saudi healthcare budget. The expected growth and aging of the population and availability of costly treatments may lead to an increase in costs. These findings are valuable for healthcare policymakers seeking to comprehend the economic challenges posed by colorectal cancer.

    Abstract Background: Familial 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).
    Methods: All 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.
    Results: A 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.
    Conclusion: An 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.

    Abstract BACKGROUND Colorectal cancer is one of the most common cancers in men and women worldwide. There are several studies showing an association between chronic schistosomiasis infection and colorectal cancer. CASE REPORT A 53-year-old woman presented with recurrent metastatic colon cancer involving the peritoneum and bilateral adnexa. The patient then underwent exploratory laparotomy that involved abdominal wall deposit resection, omentectomy, redo left hemicolectomy, peritonectomy, diaphragmatic stripping, and total abdominal hysterectomy with bilateral salpingectomy-oophorectomy, as well as hyperthermic intraperitoneal chemotherapy (HIPEC). She also underwent adjuvant chemotherapy, but on her 6th cycle, the patient suffered intolerable anal pain, diarrhea, and rectal bleeding. Her colonoscopy showed extended circumferential inflammation with loses of vascular pattern and a few rectal ulcers going up to the anastomosis site. Biopsy revealed Schistosoma mansoni eggs and marked ischemic changes. She was then managed with a single dose of Praziquantel. CONCLUSIONS Colorectal schistosomiasis infection is a rare cause of such common presentations especially in postoperative settings in a patient with recurrent metastatic colon cancer. The use of multimodality investigations and high clinical suspicion were needed for the diagnosis and to exclude other common etiologies.

    Abstract BACKGROUND Ovarian leiomyomas are rare, benign, smooth muscle, solid tumors that occur in women aged 20 to 65 years. Because their histology is benign, the prognosis for patients is good. We report the case of a patient with a huge ovarian leiomyoma who presented to the General Surgery Clinic with chronic abdominal pain and progressive abdominal distention. CASE REPORT A 45-year-old woman with a history of multiple myomectomies and a total abdominal hysterectomy with right oophorectomy presented to the General Surgery Clinic with abdominal pain and a 4-year history of progressive distention. After being examined, the patient underwent an exploratory laparotomy, during which a pelvic cyst was found that measured 3930.2 cm, was filled with serous fluid (10.5 L), and occupied most of the abdominal space. The surgery went smoothly and there were no complications during or after the procedure. The patient was discharged home 7 days later in stable condition. Postoperative pathology using hematoxylin and eosin staining and immunohistochemistry with desmin and alpha-smooth muscle actin resulted in a diagnosis of leiomyoma with cystic degeneration. When the patient was seen in the outpatient clinic 2 weeks and 3 and 6 months after surgery, her tumor markers were within normal limits. Abdominal and pelvic computed tomography scans performed at the 6-month visit showed resolution of the loculated intraperitoneal fluid and no gross local recurrence of the tumor. CONCLUSIONS Ovarian leiomyomas are difficult to diagnose preoperatively. Suspicion for one should be high, however, in patients who present with a large cystic mass in adnexal tissues, especially if they have a history of hysterectomy and oophorectomy.

    Abstract BACKGROUND Synchronous primary tumors are defined as 2 or more different histological tumors discovered in one patient at the same time or within a period of 6 months. Colorectal cancer is one of the most common cancers in the United States. Inversely, synchronous colorectal cancer and carcinoid tumors are rare. Carcinoid tumors can be classified into functioning and non-functioning tumors. Carcinoid tumors are steadily increasing in incidence. There is only 1 case reported in the literature as synchronous colorectal cancer and appendicular carcinoid. The difficulty is to manage 2 different types of malignancies at the same time. An optimal medical or chemotherapy strategy is needed. CASE REPORT A 29-year-old woman presented to the emergency room carrying with her computerized tomography (CT) abdomen and pelvic images showing bowel obstruction. Investigations confirmed an obstructing descending colon mass. She underwent colonoscopic stenting as emergency treatment with multiple biopsies. The pathology report came back positive for adenocarcinoma, and we planned to proceed with surgery. Intraoperatively, she was found to have an appendicular mass. The surgical team decided to proceed with laparoscopic-assisted subtotal colectomy. The postoperative course was uneventful, with no complications. The patient was discharged on postoperative day 6 in stable condition. CONCLUSIONS Synchronous colorectal cancer and carcinoid tumors are rare malignancies. The challenge is to find an optimal medical or chemotherapy strategy to manage both malignancies.

    Abstract BACKGROUND Neuroendocrine neoplasms (NENs) originate from cells of the endocrine and nervous systems, and they are rarely encountered in colorectal cases with no specific symptoms. The incidence and prevalence of NENs of the large bowel are increasing. Malignant colonic types are known to have poor diagnosis. The mean age of colonic NENs is the seventh decade, and the risk of NENs is increased 4-fold with affected first-degree family members. CASE REPORT A 57-year-old male patient presented to our Emergency Department with a 5-day history of severe generalized abdominal pain associated with worsening abdominal distension, history of night sweats, and weight loss. A CT scan of the abdomen and pelvis demonstrated a large heterogeneously enhancing neoplastic mass lesion involving the splenic flexure of the colon surrounded by fat stranding with a small contained leak, in addition to multiple metastatic hypodense focal hepatic lesions. Multiple lymph nodes under 1 cm in size were also noted. The patient underwent exploratory laparotomy, subtotal colectomy, ileostomy creation, and washout. The histopathological exam revealed high-grade invasive colonic neuroendocrine carcinoma, which was pT4N2bM1c, while the peritoneal lesion was metastatic carcinoma. The patient was then referred to the multidisciplinary tumor board. CONCLUSIONS Unusual presentation of neuroendocrine tumors is shown to be expected. Since colorectal NECs are rare, highly aggressive diseases and usually discovered very late, individualization of management, as well as additional research, is required.

    Abstract BACKGROUND Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is one of the treatment options in low-grade appendiceal mucinous neoplasm with peritoneal dissemination. The minimal invasive surgery approach was introduced to the field after years of traditional open technique. Multi-port laparoscopic and robotic techniques were reported with good short-term outcomes in very selected patients with low PCI scores. We describe here the first single-port laparoscopic approach of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. CASE REPORT We present a case of low-grade appendiceal mucinous neoplasm with peritoneal dissemination, in which single-port laparoscopic approach of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy was completed through a 5.5-cm incision. A 35-year-old man with no medical illness underwent laparoscopic appendectomy for acute appendicitis 3 months earlier. Postoperative surgical pathology reported a low-grade appendiceal mucinous neoplasm with positive margin. After complete assessment and Tumor Board discussion, the patient was scheduled for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. A single gel port access was inserted through a 5.5-cm peri-umbilical incision. The Peritoneal Cancer Index score was 4, and the decision was made to proceed with partial cecectomy, omentectomy, peritonectomy, and hyperthermic intraperitoneal chemotherapy with the Sugarbaker mitomycin C-based regimen. Postoperative care was carried out following the Enhanced Recovery After Surgery protocol. The patient was discharged on day 3 without any complications. CONCLUSIONS A single-port laparoscopic approach in cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is safe and feasible in very selected patients, and has the advantage of direct visualization and palpation through the incision to determine more accurate Peritoneal Cancer Index assessment in comparison to other MIS approaches. Nevertheless, additional prospective studies are needed.
