Follicular lymphoma (FL) usually has an indolent course and presents with painless, waxing and waning lymphadenopathy in the absence of systemic symptoms. It is uncommon for FL to present outside of lymph nodes, although it can develop in the gastrointestinal tract, skin, thyroid, and testes. Central nervous system (CNS) involvement in FL is rare. Most CNS lymphomas are diffuse large B-cell lymphoma, although Burkitt lymphoma, lymphoblastic lymphoma, and peripheral T-cell lymphoma are also observed. These tumors usually involve white matter but may also involve gray matter. Lymphomas of the dura are very uncommon and are usually mucosa-associated lymphoid tissue lymphomas. Here, we present a case of FL of the dura arising in a 62-year-old woman that was responsive to chemotherapy. According to a literature review, there have been 15 previously reported cases of FL of the dura. Dural FL has been most frequently treated with radiation and chemotherapy. Patients were still alive in all cases in which follow-up was reported. Although the sample size is small, these data suggest that dural FL, like other forms of FL, is an indolent disease that is associated with prolonged survival despite usually being incurable.
e16306 Background: Duodenal adenocarcinoma (DA) is a rare malignancy with poor outcomes. Tumor markers are used to assess disease response and to monitor for recurrence. Specifically, CA-19-9 and CEA have been validated for use in pancreatic cancer and colorectal cancer, respectively. However, these tumor markers have never been validated in patients with DA. We aim to assess the association of these biomarkers with clinical outcomes in patients with DA. Methods: This is a retrospective cohort study. After obtaining IRB approval (IRB202102705), we accessed the University of Florida medical records of patient treated for DA from January 1, 2006, until December 31, 2021. CA 19-9 and CEA were collected as continuous variables and were analyzed as binary variables: normal vs. high, using the maximum normal value as a cut-off (normal CA 19-9 < = 35 U/ml; CEA < = 3 ng/ml). Analysis was conducted using Kaplan Meyer curves, log-rank test and Cox proportional hazards model. Results: A total of 68 patients were included in the final analysis. Median age was 67 years and median follow-up was 22.2 months. CA 19-9 and CEA were elevated in 36.8% and 48.5% of patients, respectively. Patients with an elevated CA 19-9 had a median overall survival (OS) of 8.5 months vs. 27.4 months in patients with normal levels (HR 1.67; 95%CI 0.94–2.99; p = 0.081). Patients with an elevated CEA had a median OS of 13.4 months vs. 16.8 months in patients with normal level normal levels (HR 1.43; 95%CI 0.81–2.52; p value = 0.221). In a sensitivity analysis, a concomitant elevation of both tumoral markers was significantly associated with worsened OS (HR 1.9; 95%CI 1.05–3.06; p = 0.035). Conclusions: In patients with duodenal adenocarcinoma, elevation of both CA 19-9 and CEA was associated with a statistically significant worse overall survival. CA 19-9 level had a higher prognostic impact on OS than CEA levels. To our knowledge, this is the first study to evaluate the role of CA 19-9 and CEA in patients with DA. Further research is required for validation.[Table: see text]
We report a case of recurrent gastrointestinal bleeding in the setting of diffuse duodenal and colorectal varices. These varices were secondary to either congenital absence of the portal vein or chronic occlusion of the portal vein leading to cavernous transformation of a collateral network of varices. He was acutely managed with injection of N-butyl-2-cyanoacrylate into a large complex of duodenal varices. His hospital course was complicated by a postprocedural gastrointestinal bleed within the first 24 hours after the procedure arising from a new duodenal ulcer at the site of injection, likely secondary to ischemia after obliteration of the varices.
BACKGROUND The American Association for the Study of Liver Disease recommends screening patients with cirrhosis for hepatocellular carcinoma (HCC) using imaging with or without alpha-fetoprotein every six months. Unfortunately, screening rates remain inadequate. AIM To assess root causes of screening failure in a subspecialty hepatology clinic. METHODS The authors identified patients with cirrhosis seen in a subspecialty hepatology clinic and determined whether they underwent appropriate screening, defined as two cross-sectional images between five and seven months apart. The authors characterized the primary driver of screening failure. Finally, other hepatologists were surveyed to determine provider perceptions of screening failure causes. RESULTS 1034 patients were identified with an average age of 61 years and a mean MELD of 8.1 ± 3.8. Hepatitis C virus was the most common cirrhosis etiology. 489 (47%) underwent appropriate screening. No demographic or clinical differences were detected between those who underwent appropriate screening and those who did not. The most common etiologies of screening failure, in descending order, were: radiology unable to schedule timely imaging, provider did not order imaging, patient canceled follow up appointment, appointments scheduled too far apart, lost to follow up, no-show to radiology appointment, and provider canceled appointment. Hepatologists surveyed believed the most common cause of screening failure was no-show to radiology. CONCLUSION Rates of screening were poor even in a subspecialty hepatology clinic. Screening failure was mostly due to systemic factors such as radiology availability and time between hepatology appointments rather than individual error.
