RESUMO

INTRODUCTION: Generative artificial intelligence (AI) chatbots have recently been posited as potential sources of online medical information for patients making medical decisions. Existing online patient-oriented medical information has repeatedly been shown to be of variable quality and difficult readability. Therefore, we sought to evaluate the content and quality of AI-generated medical information on acute appendicitis. METHODS: A modified DISCERN assessment tool, comprising 16 distinct criteria each scored on a 5-point Likert scale (score range 16-80), was used to assess AI-generated content. Readability was determined using the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL) scores. Four popular chatbots, ChatGPT-3.5 and ChatGPT-4, Bard, and Claude-2, were prompted to generate medical information about appendicitis. Three investigators independently scored the generated texts blinded to the identity of the AI platforms. RESULTS: ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 had overall mean (SD) quality scores of 60.7 (1.2), 62.0 (1.0), 62.3 (1.2), and 51.3 (2.3), respectively, on a scale of 16-80. Inter-rater reliability was 0.81, 0.75, 0.81, and 0.72, respectively, indicating substantial agreement. Claude-2 demonstrated a significantly lower mean quality score compared to ChatGPT-4 (p = 0.001), ChatGPT-3.5 (p = 0.005), and Bard (p = 0.001). Bard was the only AI platform that listed verifiable sources, while Claude-2 provided fabricated sources. All chatbots except for Claude-2 advised readers to consult a physician if experiencing symptoms. Regarding readability, FKGL and FRE scores of ChatGPT-3.5, ChatGPT-4, Bard, and Claude-2 were 14.6 and 23.8, 11.9 and 33.9, 8.6 and 52.8, 11.0 and 36.6, respectively, indicating difficulty readability at a college reading skill level. CONCLUSION: AI-generated medical information on appendicitis scored favorably upon quality assessment, but most either fabricated sources or did not provide any altogether. Additionally, overall readability far exceeded recommended levels for the public. Generative AI platforms demonstrate measured potential for patient education and engagement about appendicitis.

RESUMO

An elderly man was referred to vascular surgery on incidental discovery of a left retroperitoneal mass ultimately found to be of left renal vein (LRV) origin. He initially presented with recurring lower back pain. CT of the abdomen/pelvis showed a 6.0×5.5 cm lobulated retroperitoneal mass anterior to the infrarenal aorta. Resection of the mass necessitated a multidisciplinary team consisting of medical oncologists, radiation oncologists, urologists and vascular surgeons. In efforts to obtain an R0 margin, en-bloc resection of the LRV from its confluence with the inferior vena cava (IVC) was necessary. A primary repair of the IVC was performed with preservation of the left kidney. The patient's back pain has since resolved after the surgery. A literature search found IVC reconstructions to be safe and effective in the removal of vascular leiomyosarcomas.

RESUMO

Pancreatic neuroendocrine tumors (PNETs) are characterized by dysregulated signaling pathways that are crucial for tumor formation and progression. The efficacy of traditional therapies is limited, particularly in the treatment of PNETs at an advanced stage. Epigenetic alterations profoundly impact the activity of signaling pathways in cancer development, offering potential opportunities for drug development. There is currently a lack of extensive research on epigenetic regulation in PNETs. To fill this gap, we first summarize major signaling events that are involved in PNET development. Then, we discuss the epigenetic regulation of these signaling pathways in the context of both PNETs and commonly occurring-and therefore more extensively studied-malignancies. Finally, we will offer a perspective on the future research direction of the PNET epigenome and its potential applications in patient care.

RESUMO

Metastatic, malignant phyllodes tumor (PT) of the breast is a rare and aggressive neoplasm. Currently, there is no agreed upon consensus as to best management practices. A systematic review of literature was conducted investigating surgical, chemotherapeutic, and radiotherapeutic management for metastatic PT. Databases employed to identify articles included Embase, PubMed, and SAGE Journals. Diagnosis of metastatic PT has been of significant difficulty to radiologists as it is often confused with fibroadenomas. Surgically, metastatectomy has been correlated with increased overall survival (of 25.9 versus 9.9 months; P = .01). Radiotherapy has often been associated with palliation and pain control in metastatic, malignant neoplasia. However, one study showed that in malignant PT, radiation was associated with significantly lower rates of local recurrence (OR: 0.048 versus 0.209). Anthracycline containing chemotherapy regimens has been associated with improved overall survival (22.4 months versus 13.2 months; P = .040). Further research must be conducted into this rare malignancy to elucidate accurate diagnosis and care for patients with advanced metastatic or malignant phyllodes tumors.

RESUMO

Esophageal squamous cell carcinoma (ESCC) is characterized by the development of cancer in the esophageal squamous epithelium through a step-by-step accumulation of genetic, epigenetic, and histopathological alterations. Recent studies have demonstrated that cancer-associated gene mutations exist in histologically normal or precancerous clones of the human esophageal epithelium. However, only a small proportion of such mutant clones will develop ESCC, and most ESCC patients develop only one cancer. This suggests that most of these mutant clones are kept in a histologically normal state by neighboring cells with higher competitive fitness. When some of the mutant cells evade cell competition, they become "super-competitors" and develop into clinical cancer. It is known that human ESCC is composed of a heterogeneous population of cancer cells that interact with and influence their environment and neighbors. During cancer therapy, these cancer cells not only respond to therapeutic agents but also compete with each other. Therefore, competition between ESCC cells within the same ESCC tumor is a constantly dynamic process. However, it remains challenging to fine-tune the competitive fitness of various clones for therapeutic benefits. In this review, we will explore the role of cell competition in carcinogenesis, cancer prevention, and therapy, using NRF2, NOTCH pathway, and TP53 as examples. We believe that cell competition is a research area with promising targets for clinical translation. Manipulating cell competition may help improve the prevention and therapy of ESCC.

RESUMO

Herpes simplex virus (HSV) pseudotumor is a rare presentation of HSV and has not been previously reported in the stomach. A 51-year-old man with a medical history of HIV presented with new-onset dysphagia. Endoscopy revealed an HSV-positive mass at the gastroesophageal junction. After antiviral treatment, the patient returned with a 100-pound unintentional weight loss. Computed tomography showed an infiltrative mass with enlarged lymph nodes. The mass had progressed despite HSV treatment, and a repeat set of biopsies were negative for HSV with cells concerning for B-cell lymphoma. The patient was taken to the operating room for a full-thickness biopsy because of increasing concern for malignancy. The procedure was complicated by gastric perforation, leading to a total gastrectomy. Final pathology demonstrated an HSV-positive pseudotumor, negative for malignancy. It is important to diagnose gastric masses, especially in HIV-positive patients at high risk of infection and malignancy. However, immunocompromised patients with an HSV-positive mass should be treated for HSV pseudotumor with a longer than standard duration of antiviral therapy.

RESUMO

BACKGROUND: Mixed medullary-papillary thyroid carcinoma (MMPTC) and mixed medullary-follicular thyroid carcinoma (MMFTC) are rare variants with little known regarding behavior and prognosis. METHODS: Using the National Cancer Database (NCDB), demographics, clinicopathologic features, treatment, and overall survival (OS) from patients with MMPTC and MMFTC were compared to more prevalent subtypes. RESULTS: There were 296,101 patients: 421 MMPTC (0.14%), 133 MMFTC (0.04%), 263,140 PTC (88.87%), 24,208 FTC (8.18%) and 8,199 MTC (2.77%). Compared to PTC, MMPTC and MMFTC patients were older (p < 0.001) with a higher Charlson-Deyo comorbidity index (p < 0.001). Mixed tumors exhibited lower rates of nodal disease but more distant metastases compared to PTC (p < 0.001). MMPTC demonstrated lower estimated 10-year OS than PTC and FTC (76.04%vs 89.04% and 81.95%,p < 0.001), yet higher than MTC (70.29%,p < 0.001). MMFTC had a worse OS compared to all groups (63.32%,p < 0.001). CONCLUSION: Patients with MMFTC had significantly worse OS compared to DTC, portending a worse prognosis.

RESUMO

BACKGROUND: Gastric neuroendocrine tumors (gNETs) are rare cancers for which surgery may improve survival. We aim to determine if facility type affects treatment and survival outcomes. METHODS: The NCDB was queried for patients with gNET from 2004-2016 and stratified into Academic/Research Program (ARP), Community Cancer Program (CCP), Comprehensive Community Cancer Program (CCCP), or Integrated Network Cancer Program (INCP). Overall survival along with clinical and demographic features was compared. RESULTS: Median survival was improved in patients treated at an academic program: 137.3 months versus 88.0, 96.3, and 100.2 for CCP, CCCP, INCP, respectively (P < .0001). Patients treated at academic centers were more likely to have surgery (64.2% vs 59.1%, 57.5%, 51.4%, P < .0001). After propensity matching for age, race, grade, stage, insurance status, and comorbidity score, survival benefit from treatment at an academic center remained (P = .03), particularly for patients undergoing surgery (P < .0001) and chemotherapy (P = .04). CONCLUSION: Patients with gNET treated at an academic hospital had improved median survival after propensity matching and may benefit from treatment at academic rather than community medical centers.

RESUMO

Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare form of primary hepatic collision tumor, with an incidence ranging from 0.4 to 14.2%. Given the diagnostic challenges and lack of randomized trials, standardized treatment has yet to be established. We aim to review the literature to summarize the diagnosis, molecular characteristics, current treatment modalities, and challenges for cHCC-CC. A literature review was performed using PubMed. We included studies investigating and describing cHCC-CC, focusing on surgical, medical, and radiologic treatments. Overall prognosis is poor, with a 5-year survival rate under 30%. Minor or major hepatectomy with R0 resection is the only curative treatment; however, recurrence is likely (as high as 50% within 5 years). The role of liver transplantation is also highly debated given the biliary nature of these tumors, with cHCC-CC as a relative contraindication for liver transplantation. Although gemcitabine-based treatments had higher progression-free survival over sorafenib, there is no standard chemotherapy regimen. Treatment with gemcitabine and platinum demonstrates improved disease control rates compared to gemcitabine in conjunction with 5-fluorouracil (78.4% verse 38.5% respectively). Additionally, platinum-containing chemotherapy regimens exhibit a higher overall response rate than non-platinum regimens (21.4% verse 7.0% respectively). These molecular-directed therapies have prolonged survival for HCC, but further investigation needs to be done to assess their utility in patients with cHCC-CC. cHCC-CC is a rare and complex subset of primary hepatic neoplasms with a dismal prognosis and unstandardized treatment options. Further trials need to be performed to investigate systemic chemotherapy and immunotherapy options for patients with unresectable disease.

RESUMO

INTRODUCTION: The 2014 Medicaid expansion was intended to improve access to care. We hypothesized that Medicaid expansion would be associated with improved gastric cancer (GC) outcomes. METHODS: We selected patients with a new primary diagnosis of GC from the National Cancer Database. We compared states that expanded Medicaid in 2014 to those that did not. We compared pre-and post-expansion intervals 2012-2013 and 2015-2016. RESULTS: There was an increase in patients diagnosed with stage 0-2 GC from 38% to 41.5% [p < 0.01] in expansion states (ES), but no change at 38.9% in non-expansion states (NES). Uninsured and Medicaid patients diagnosed with stages 0-2 GC increased in ES from 32.4% to 37.8% [p = 0.01] and decreased in NES from 29.7% to 27.3% [p = n.s.]. Uninsured and Medicaid patients receiving treatment rose from 87.0% to 90.3% in ES [p < 0.01] and in NES 83.9%-84.9% [p = n.s.]. Twelve-month survival for ES rose from 68.1% to 70.6% [p = 0.03] and in NES decreased 65.2%-65.1% [p = n.s.]. CONCLUSION: Increased healthcare access may be related to earlier diagnosis and improved outcomes in GC.

RESUMO

BACKGROUND: In advanced malignant bowel obstruction, decompressive gastrostomy tubes (GTs) may not be feasible due to ascites, peritoneal carcinomatosis, and altered gastric anatomy. Whereas nasogastric tubes (NGTs) allow temporary decompression, percutaneous transesophageal gastrostomy tubes (PTEGs) are an alternative method for long-term palliative decompression. This study performed a scoping review to determine outcomes with PTEG in advanced malignancies. METHODS: A systematic literature search was performed to include all studies that reported the clinical results of PTEGs for malignancy. No language, national, or publication status restrictions were used. RESULTS: The analysis included 14 relevant studies with a total of 340 patients. In 11 studies, standard PTEGs were inserted with a rupture-free balloon's placement into the mouth or nose and esophageal puncture under fluoroscopy or ultrasound, followed by a guidewire into the stomach with placement of a single-lumen tube. Of 340 patients, 65 (19.1%) had minor complications, and 5 (2.1%) had significant complications, including bleeding and severe aspiration pneumonia. Of 171 patients, 169 with PTEGs (98.8%) reported relief of nasal discomfort from NGT and alleviation of obstructive symptoms. The one randomized controlled trial reported a significantly higher quality of life with PTEGs than with NGTs. CONCLUSIONS: When decompression for advanced malignancy is technically not feasible with a gastrostomy tube, the PTEG is a viable, safe option for palliation. The PTEG is associated with lower significant complication rates than the gastrostomy tube and significantly higher patient-derived outcomes than the NGT.

RESUMO

BACKGROUND: Robotic and laparoscopic hepatectomies having increased utilization as minimally invasive techniques are explored for hepatobiliary malignancies. Although the data on outcomes from these 2 approaches are emerging, the cost-benefit analysis of these approaches remains sparse. This study compares the costs associated with robotic vs. laparoscopic liver resections, taking into account 30-day complications. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database, a propensity-matched cohort of patients with laparoscopic or robotic liver resections between 2014 and 2017 was identified. Costs were assigned to perioperative variables, including operating room (OR) time, length of stay, blood transfusions, and 30-day complications. Cost estimates were obtained from the Centers for Medicare and Medicaid Services billing data (2017), American Hospital Association data (2017), relevant literature, and local institutional cost data. RESULTS: In our matched cohort of 454 patients (227 per group), total costs associated with laparoscopic liver resections were estimated at $5.5 M ($24 K per patient) vs. $6.8 M ($29.8 K per patient) for robotic liver resections (21.3% difference, P < .001). The higher cost associated with robotic hepatectomies was related to blood transfusions ($22.0 K vs. $12.1 K, P = .02), length of stay ($2.05 M vs. $1.76 M, P = .046), and OR time ($4.01 M vs. $3.24 M, P < .0001). DISCUSSION: Robotic hepatectomies were associated with higher costs compared to laparoscopic hepatectomies. The 2 major contributors to the cost disparity were increased OR time and increased length of stay. Future studies are warranted to analyze high-volume Minimally Invasive Surgery surgeons' impact in specialty centers on potentially mitigating this current cost disparity.

RESUMO

BACKGROUND: Mesenchymal stem cells have been proven to promote cellular recruitment and remodeling during healing. Considering challenges encountered in the healing process of esophageal injury, we sought to evaluate the effect of human adipose derived stem cells (hASC) on esophageal injury with stent and to assess the feasibility of submucosal hASC injection as a mechanism of delivery. METHODS: An intrabdominal esophagotomy was created in rodents with placement of an expandable fully covered metal esophageal stent. A submucosal injection of 2 × 106 hASC was delivered in experimental animals. Animals were sacrificed on postoperative day 3 (POD3) or 7 (POD7). Macroscopic, immunohistochemical and immunofluorescence analyses were conducted to assess for markers of healing and viability of transplanted cells. RESULTS: hASC were identified within submucosal and muscular layers with proliferation demonstrated in respective areas on anti-Ki67 stained sections. Lower adhesion and abscess scores were observed in hASC specimens without significant statistical difference. Prevalence of submucosal collagen was increased in samples treated with hASC compared to control, with abundant collagen deposition demonstrated within the POD7 group. Granulation tissue at the site of esophageal injury was more prominent in tissue sections treated with hASC compared to control, with significantly higher density at POD3 (control 1.94 versus hASC 2.83, P < 0.01). CONCLUSIONS: Presence of hASC at the site of an esophageal injury may enhance wound healing predominantly through increased granulation and decreased inflammation in conjunction with esophageal stent placement. Targeted submucosal injection at the time of esophageal stent placement is an effective delivery method of hASC therapy.

RESUMO

BACKGROUND: Duodenal adenocarcinoma treatment consists of either simple or radical surgical resection. Existing evidence suggests similar survival outcomes between the two but is limited by small numbers and single-institution analysis. We aim to compare survival after partial versus radical resection for duodenal adenocarcinoma using the National Cancer Database (NCDB). METHODS: Using NCDB results from 2004 to 2014, we compared patients with duodenal adenocarcinoma undergoing partial resection (n = 1247) and radical resection (n = 1240) by age, sex, facility type, facility location, cancer stage, cancer grade, lymph node sampling, node status, tumor size, margin status, neoadjuvant therapy, and adjuvant therapy using chi-square analysis. Survival was compared using propensity matching. RESULTS: Patients undergoing partial resection had overall earlier cancer stage, more favorable tumor grade, and were less likely to undergo lymph node sampling and neoadjuvant therapy. When overall survival was compared between the 2 propensity-matched groups, the median survival was 46.7 months after partial resection and 43.2 months after radical resection (P = .329), and overall survival was similar between the 2 groups (P = .894). The use of adjuvant therapy demonstrated improved survival over either surgery alone (P < .0001, P = .0037). CONCLUSION: Partial resection did not demonstrate worse survival outcomes than radical resection for duodenal adenocarcinoma. The use of adjuvant therapy in addition to surgery demonstrated improved survival regardless of surgery type and played a larger role in survival than the type of surgery. Our findings provide evidence to support the continued use of both partial and radical surgical resections to treat duodenal malignancy.

RESUMO

INTRODUCTION: There is a paucity of data on the role of metastasectomy for metastatic anal cancer on survival outcomes. We aim to define the role of metastasectomy in stage IV anal cancer. METHODS: National Cancer Database (NCDB) from 2004 to 2014 was accessed to include patients with metastatic anal cancer, excluding adenocarcinoma, neuroendocrine, and 'other' histologies. We compared patients undergoing metastasectomy (n = 165) to those who did not have metastasectomy (n = 2093) by age, sex, cancer grade, and site of metastasis, including metastasis to bone, liver, and lung, using chi-square analysis. The primary outcome was overall survival. RESULTS: Patients had equal distribution of metastatic sites between those who underwent metastasectomy versus no metastasectomy: bone (7.64% vs 4.85%, p = 0.22), brain (0.24% vs 0%, p = 1.0), liver (23.22% vs 29.70%, p = 0.07), and lung (11.85% vs 9.09%, p = 0.38). Survival following metastasectomy was increased at one year (71% vs. 61%, p = 0.016), two years (50% vs. 38%, p = 0.014), and five years (30% vs. 19%, p = 0.025). Median overall survival was increased (23 months vs. 16 months; p = 0.015) for patients with metastasectomy. Survival increases were demonstrated only in the group with liver metastasis undergoing metastasectomy. When stratifying for liver metastases only, median overall survival time was further increased (34 months vs. 16 months; p < 0.0001) following metastasectomy. CONCLUSION: These results demonstrate a survival benefit for hepatic metastasectomy in stage IV anal cancer. Our findings demonstrate a potential survival benefit in highly select patients with metastatic anal cancer to the liver. These findings support further investigation in a randomized clinical trial to delineate these findings.

RESUMO

INTRODUCTION: Adjuvant therapy is recommended in duodenal adenocarcinoma (DA), but the role of neoadjuvant therapy remains undefined. We compared the effect of neoadjuvant therapy to adjuvant therapy on overall survival, 30-day, and 90-day mortality following the resection of DA. METHODS: A retrospective review of the National Cancer Database was performed on patients with DA who received either adjuvant or neoadjuvant therapy in addition to surgical resection. Propensity score matching was done for patient, socioeconomic, and tumor characteristics. Overall survival, 30-day, and 90-day mortality were compared. RESULTS: A total of 112 patients were identified; 55 received adjuvant therapy; 57 received neoadjuvant therapy. There was no difference in 30-day (0% vs. 1.75%; P = 1.00), 90-day mortality (1.82% vs. 7.02%; P = .36), nor overall survival (1 yr: 86% vs. 76; 3 yr: 49% vs. 46%; 5 yr: 42% vs. 39%; P = .28). CONCLUSIONS: There was no difference in overall survival after propensity score matched analysis.

RESUMO

BACKGROUND: Perforated gastric ulcers are surgical emergencies with paucity of data on the preferred treatment modality of resection versus omental patch. We aim to compare outcomes with ulcer repair and gastric resection surgeries in perforated gastric ulcers after systematic review of literature. METHODS: A systematic literature search was performed for publications in PubMed Medline, Embase, and Cochrane Central Register of Controlled Trials. We included all studies which compared ulcer repair vesus gastric resection surgeries for perforated gastric ulcers. We excluded studies which did not separate outcomes gastric and duodenal ulcer perforations. RESULTS: The search included nine single-institution retrospective reviews comparing ulcer repair (449 patients) versus gastric resection surgeries (212 patients). Meta-analysis was restricted to perforated gastric ulcers and excluded perforated duodenal ulcers. The majority of these studies did not control for baseline characteristics, and surgical strategies were often chosen in a non-randomized manner. All of the studies included were at high risk of bias. The overall odds ratio of mortality in ulcer repair surgery compared to gastric resection surgery was 1.79, with 95% CI 0.72 to 4.43 and p-value 0.209. CONCLUSION: In this meta-analysis, there was no difference in mortality between the two surgical groups. The overall equivalence of clinical outcomes suggests that gastric resection is a potentially viable alternative to ulcer repair surgery and should not be considered a secondary strategy. We would recommend a multicenter randomized control trial to evaluate the surgical approach that yields superior outcomes. LEVEL OF EVIDENCE: Systematic review and meta-analysis, level III.

RESUMO

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has expanded the utilization of telemedicine in clinical practice to minimize potential risks to both patients and providers. We aim to describe the perception of telemedicine by both surgical patients and providers to understand the preferences for future incorporation in future surgical practice. METHODS: An anonymous survey was administered to providers that transitioned clinic visits to telemedicine encounters since the start of the COVID-19 pandemic. In the second part of the study, patients who underwent video telemedicine appointments answered survey questions via telephone. RESULTS: Twenty-six out of 36 (72.7%) providers responded. Over 75% reported that they could effectively communicate with patients over telemedicine. Six (23.1%) reported that they could adequately assess surgical sites. Of 361 patients, 187 consented to the study (consent rate 51.8%). Among patients, the most common result to choose a telemedicine appointment was to avoid the risk of COVID-19 transmission (84, 44.9%), though the minority reported that they would choose telemedicine after the pandemic (64, 34.2%). Those patients who would choose an in-person visit were more likely to have a higher Charlson Comorbidity Score, body mass index, and use friends or family for transportation. In open-ended feedback, patients suggested that telemedicine would be better suited for long-term follow-up rather than the immediate postoperative setting. CONCLUSIONS: Patients and providers reported a high degree of satisfaction using telemedicine during the COVID-19 pandemic but noted concern with limited physical examinations. Telemedicine may be suited for preoperative evaluation and medium-term and long-term postoperative follow-up for surgical patients.
