Rectal prolapse (RP) is a rare condition presenting as a partial or complete protrusion of the rectum or as mucosa through the anal canal, and it usually occurs in the elderly or females with multiple risk factors. An initial presentation of incarcerated RP is even rarer. We present a case of a previously healthy 39-year-old man who presented with an incarcerated RP that necessitated urgent perineal proctosigmoidectomy (Altemeier procedure), with diverting sigmoid colostomy, followed by a reversal of the colostomy three months later. This case highlights the importance of surgical management (the modified Altemeier procedure) for a patient with an incarcerated RP. There are no specific guidelines for management of RP; all the recommendations and latest approaches are patients-based approaches according to their presentations, risk factors, age, and gender.

Cholangiocarcinoma (CCA) is a hepatic malignancy that has a rapidly increasing incidence. CCA is anatomically classified into intrahepatic (iCCA) and extrahepatic (eCCA), which is further divided into perihilar (pCCA) and distal (dCCA) subtypes, with higher incidence rates in Asia. Despite its rarity, CCA has a low 5-year survival rate and remains the leading cause of primary liver tumor-related death over the past 10–20 years. The systemic therapy section discusses gemcitabine-based regimens as primary treatments, along with oxaliplatin-based options. Second-line therapy is limited but may include short-term infusional fluorouracil (FU) plus leucovorin (LV) and oxaliplatin. The adjuvant therapy section discusses approaches to improve overall survival (OS) post-surgery. However, only a minority of CCA patients qualify for surgical resection. In comparison to adjuvant therapies, neoadjuvant therapy for unresectable cases shows promise. Gemcitabine and cisplatin indicate potential benefits for patients awaiting liver transplantation. The addition of immunotherapies to chemotherapy in combination is discussed. Nivolumab and innovative approaches like CAR-T cells, TRBAs, and oncolytic viruses are explored. We aim in this review to provide a comprehensive report on the systemic and locoregional therapies for CCA.

Background: Idiopathic duodenal hematoma is a rare clinical condition, typically associated with trauma, anticoagulation therapy, gastrointestinal procedures, or coagulopathies. We present a unique case of spontaneous duodenal hematoma in a patient without identifiable risk factors. Case presentation: We present the case of a 60-year-old Asian woman who presented to the emergency room (ER) with a 10-day history of progressive abdominal pain, early satiety, nausea, and vomiting. She had no history of trauma, anticoagulant use, or underlying predisposing conditions. On clinical evaluation, she was hemodynamically stable, and the initial laboratory results were unremarkable except for signs of dehydration and inflammation. A computed tomography (CT) scan revealed a heterogeneous lesion in the second portion of the duodenum, initially raising suspicion of a duodenal tumor. Further evaluation with magnetic resonance imaging (MRI) confirmed a duodenal hematoma with compression of the adjacent pancreas. Management and Outcome: The patient was managed conservatively with bowel rest, nasogastric decompression, intravenous (IV) fluid, and a proton pump inhibitor (PPI). Serial imaging demonstrated gradual hematoma resolution, with progressive improvement in her symptoms. She was discharged in stable condition and returned to normal activity after three weeks with complete hematoma resolution as seen on follow-up imaging. Conclusions: This case highlights the importance of considering spontaneous hematoma in the differential diagnosis of abdominal pain, even without risk factors. Early diagnosis and conservative treatment remain the mainstay of management and can lead to full recovery in uncomplicated cases.

Background: The use of regorafenib and 5-fluorouracil in the management of refractory metastatic colorectal cancer has gained increasing attention due to their demonstrated efficacy in extending the survival of patients with colorectal cancer. This study aims to discuss the effect of using regorafenib and 5-fluorouracil combination therapy in refractory metastatic colorectal cancer patients. Case Presentation: We present a case report of a 68-year-old female patient with KRAS G12D and PIK3CA mutations who was diagnosed with stage IV-C colon cancer. She was referred to hospice care and subsequently received therapeutic intervention with 56 cycles of regorafenib and 5-fluorouracil for 31 months while maintaining stable disease (SD). The patient exhibited good tolerance with minimal adverse effects, including Grade I-II Hand–Foot Syndrome. Conclusions: Our case showed the feasibility of using Regorafenib and 5-fluorouracil combination therapy in stage IV refractory metastatic colorectal cancer treatment, which resulted in an improvement in the overall survival after she was referred to Hospice care. Utilizing this case report may provide valuable input in managing refractory metastatic colorectal cancer, given the prolonged survival and the clinical meaningfulness of this regimen in our patient.

Paragangliomas are rare extra-adrenal neuroendocrine tumors originating from chromaffin tissue that present a diagnostic and therapeutic challenge due to their diverse clinical manifestations and low incidence. While these tumors often manifest as catecholamine-secreting functional tumors, their clinical presentation can vary, leading to delayed diagnosis and challenging management. This study presents the case of a 22-year-old patient with cardiac paraganglioma who initially presented with angina-like symptoms, highlighting the importance of considering this rare condition in young individuals with nonspecific complaints. Diagnostic imaging, including transthoracic echocardiography, CT angiography, and MRI, played a crucial role in identifying the tumor’s location and vascularization. Surgical excision, including pulmonary artery graft and CABG, was the primary management approach, which was accompanied by intraoperative complications that later led to CCU admission, followed by postoperative complications, ultimately leading to the patient’s death. This case highlights the significance of early recognition and management of complications following a surgical approach to treat paragangliomas.

The COVID-19 pandemic has impacted every country in the world. With more than 400 million cases and more than 5.5 million deaths. The FDA either approved or authorized the emergency use for three vaccines against COVID-19. The treatment options of COVID-19 are very limited. Multiple complementary and alternative medicine modalities were suggested to be efficacious in the treatment of COVID-19 such as Thymoquinone. The effects of Thymoquinone have been examined and multiple studies indicate a promising beneficial effect. However, the current body of research is limited in terms of its scope, quality, and quantity. While higher-quality studies are required, physicians do not routinely recommend the use of marketed supplements of natural products, including Thymoquinone for COVID-19. Given the numerous suggested positive effects of Thymoquinone, including anti-inflammatory and antimicrobial properties, additional research is required to confirm or refute these promising benefits. Complementary and alternative medicine is an area that requires additional evidence-based practice and research to confirm effects observed in clinical practice.

Background and Clinical Significance: Pancreatic cancer was the third leading cause of cancer-related mortality in the United States in 2020 after lung and colorectal cancers. The prevalence of pancreatic cancer has been increasing and is projected to continue rising through 2040, with an estimated 355,317 additional cases expected. We present the case of an 81-year-old patient with metastatic pancreatic ductal adenocarcinoma (PDAC) who tolerated NALIRIFOX for a year with grade 1 adverse events. Case presentation: An 81-year-old Asian male presented with abdominal pain associated with weight loss and fatigue. An abdominal computed tomography (CT) scan showed a mass in the body of the pancreas measuring 3.5 cm with an infiltrative appearance invading the retroperitoneum and encasing the splenic artery. A biopsy confirmed poorly differentiated PDAC. The patient received 13 cycles of NALIRIFOX in a palliative setting over the course of one year, demonstrating excellent tolerance aside from minor toxicities, including worsening of pre-existing macrocytic anemia, treatment-related grade 1 neuropathy, diarrhea, and thrombocytopenia. A subsequent CT scan revealed disease progression, and the patient was switched to second-line therapy. However, per his preference, the patient was referred to hospice care and passed away a few days later. Conclusions: This case highlights the excellent tolerability of NALIRIFOX in an elderly patient, with minimal adverse events observed, which is uncommon among similar patient populations.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with poor prognosis due to late-stage diagnosis, limited surgical resectability, and frequent recurrence. Traditional biomarkers like CA19-9 and imaging techniques often fail to detect minimal residual disease (MRD) or early recurrence. Circulating tumor DNA (ctDNA) is a promising non-invasive biomarker that may provide early detection of disease recurrence, offering a potential improvement in patient management. This study aimed to assess the utility of ctDNA as a prognostic tool for PDAC patients, specifically in predicting recurrence and overall survival (OS). Methods: This retrospective study analyzed data from 39 PDAC patients who underwent surgery and were monitored for ctDNA levels using Signatera™, a tumor-informed multiplex PCR next-generation sequencing assay. Blood samples were collected both preoperatively and postoperatively, and ctDNA levels were measured to detect MRD. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ctDNA were compared with CA19-9 in detecting disease recurrence. Clinical outcomes, including progression-free survival (PFS) and OS, were evaluated in relation to ctDNA status. Results: Among 39 patients, 153 plasma samples were analyzed, with 17 patients testing positive for ctDNA. Sensitivity of ctDNA in detecting relapse was 91%, compared to 83% for CA19-9, with combined testing reaching 98% sensitivity. ctDNA positivity was associated with significantly shorter OS and PFS, with patients testing negative for ctDNA having a median OS of 37.6 months versus 13.4 months in ctDNA-positive patients (p = 0.003). The median time from ctDNA positivity to imaging-confirmed relapse was 81 days. Positive ctDNA was also linked to higher rates of lymphovascular invasion and positive surgical margins, highlighting the aggressive nature of the disease in these patients. Conclusions: CtDNA is a highly sensitive and specific biomarker for detecting MRD and predicting recurrence in PDAC patients, offering superior performance over CA19-9. Positive ctDNA results were associated with worse prognosis, including shorter OS and PFS, and may help guide treatment decisions. These findings suggest that ctDNA could be a valuable tool for personalized management in PDAC, though further prospective studies are needed to validate its clinical role in treatment stratification.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. Atezolizumab plus bevacizumab (Atezo/Bev) has emerged as a first-line therapy for unresectable HCC (uHCC), improving overall and progression-free survival (OS, overall survival and PFS, progression-free survival) in IMbrave150. This study evaluates the real-world efficacy and safety of Atezo/Bev in uHCC. Methods: A retrospective analysis was performed on 87 patients (median age 68 years) treated with Atezo/Bev at Houston Methodist Hospital between January 2020 and June 2023. Demographics, treatment patterns, radiological response, OS, PFS, and toxicities were reviewed. Atezo/Bev was administered per FDA guidelines (atezolizumab 1200 mg plus bevacizumab 15 mg/kg every 3 weeks). Results: Of 87 patients, 78% were male, 71% White, and 70% had BCLC stage C disease. Most (60%) had Child–Pugh class A liver function, and 62% had viral hepatitis. Median OS was 15.1 months (95% CI: 10.57–25.97) and PFS was 9.1 months (95% CI: 7.4–21.07). Objective response rate was 31.3% (CR 7.2%, PR 25%, SD 52%, PD 16%). OS was longer in CP A versus CP B patients (21.2 vs. 5.2 months, p < 0.001) and in those receiving post-Atezo/Bev locoregional therapy (21.2 vs. 10.4 months, p = 0.043). Discontinuation due to toxicity occurred in 14%, mainly gastrointestinal bleeding and fatigue. Conclusions: Atezo/Bev demonstrated favorable real-world efficacy and manageable toxicity in uHCC, particularly in patients with preserved liver function or multimodal therapy.

Background: Colorectal carcinoma (CRC) is one of the most common cancer types along with breast, prostate, and lung cancer. Many patients with CRC present with metastatic disease despite receiving standard first- and second-line therapies; thus emerges the demand for implementing new therapies that could improve outcomes among CRC patients. This case series was conducted to assess the efficacy and safety of regorafenib plus 5-fluorouracil (5-FU) in patients with refractory metastatic CRC (mCRC). Methods: We conducted a retrospective analysis of data from adult patients aged 18 and above who were diagnosed with refractory mCRC and received regorafenib plus 5-FU combination therapy at Houston Methodist Hospital between November 2017 and October 2023. Our study focuses on assessing key outcomes, including Overall Survival [OS], Progression-Free Survival [PFS], and safety. Results: Among the 12 patients we included in this study who underwent regorafenib plus 5-FU combination therapy for refractory mCRC after receiving at least three prior lines of treatment, the best response for six patients (50%) was successfully achieved, with disease control within 7–12 weeks from therapy initiation. Patients had an overall good tolerance for this treatment regimen and reported only the most common adverse events, including Hand-Foot Syndrome (HFS), mucositis, and hypertension (HTN), which were mostly resolved with dose adjustment of medications. Conclusions: This study highlights that using a combination of regorafenib plus 5-FU can be a potential treatment option for patients with refractory mCRC. Additional research, including prospective clinical trials, is required to assess the effectiveness and safety of regorafenib and 5-FU combination therapy in comparison to other currently limited treatment options.
