A Multimodal Approach to Control of Massive Hemorrhage Secondary to Rectal Cancer.

The management of patients with symptomatic rectal masses can be challenging and is further complicated in cases of advanced age, comorbidities, prior surgeries, and acute hemorrhage. In this report, we describe a patient who presented with massive hemorrhage from a 7 cm low rectal tumor with subsequent cardiac arrest. After return of spontaneous circulation, emergent pelvic angiography identified extensive tumor enhancement and blush off the anterior division of the right internal iliac artery from multiple parasitized vessels. The right internal iliac artery was embolized with multiple microcoils to decrease the tumor blood supply and slow the rate of bleeding. The patient was then taken directly from the angiography suite to radiation oncology for planning CT, and within several hours, underwent his first session of radiation. In conjunction with angioembolization, short-course radiation therapy can be an effective treatment modality for advanced bleeding rectal tumors not amenable to surgical resection.

Baseline Features and Reasons for Nonparticipation in the Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) Study, a Colorectal Cancer Screening Trial.

Importance: The Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) randomized clinical trial sought to recruit 50 000 adults into a study comparing colorectal cancer (CRC) mortality outcomes after randomization to either an annual fecal immunochemical test (FIT) or colonoscopy. Objective: To (1) describe study participant characteristics and (2) examine who declined participation because of a preference for colonoscopy or stool testing (ie, fecal occult blood test [FOBT]/FIT) and assess that preference's association with geographic and temporal factors. Design, Setting, and Participants: This cross-sectional study within CONFIRM, which completed enrollment through 46 Department of Veterans Affairs medical centers between May 22, 2012, and December 1, 2017, with follow-up planned through 2028, comprised veterans aged 50 to 75 years with an average CRC risk and due for screening. Data were analyzed between March 7 and December 5, 2022. Exposure: Case report forms were used to capture enrolled participant data and reasons for declining participation among otherwise eligible individuals. Main Outcomes and Measures: Descriptive statistics were used to characterize the cohort overall and by intervention. Among individuals declining participation, logistic regression was used to compare preference for FOBT/FIT or colonoscopy by recruitment region and year. Results: A total of 50 126 participants were recruited (mean [SD] age, 59.1 [6.9] years; 46 618 [93.0%] male and 3508 [7.0%] female). The cohort was racially and ethnically diverse, with 748 (1.5%) identifying as Asian, 12 021 (24.0%) as Black, 415 (0.8%) as Native American or Alaska Native, 34 629 (69.1%) as White, and 1877 (3.7%) as other race, including multiracial; and 5734 (11.4%) as having Hispanic ethnicity. Of the 11 109 eligible individuals who declined participation (18.0%), 4824 (43.4%) declined due to a stated preference for a specific screening test, with FOBT/FIT being the most preferred method (2820 [58.5%]) vs colonoscopy (1958 [40.6%]; P < .001) or other screening tests (46 [1.0%] P < .001). Preference for FOBT/FIT was strongest in the West (963 of 1472 [65.4%]) and modest elsewhere, ranging from 199 of 371 (53.6%) in the Northeast to 884 of 1543 (57.3%) in the Midwest (P = .001). Adjusting for region, the preference for FOBT/FIT increased by 19% per recruitment year (odds ratio, 1.19; 95% CI, 1.14-1.25). Conclusions and Relevance: In this cross-sectional analysis of veterans choosing nonenrollment in the CONFIRM study, those who declined participation more often preferred FOBT or FIT over colonoscopy. This preference increased over time and was strongest in the western US and may provide insight into trends in CRC screening preferences.

A Unique Presentation of Concurrent Duodenal and Peritoneal Metastasis From Head and Neck Cancer.

Metastatic disease to the duodenum or peritoneum from a primary head and neck carcinoma is an extremely rare presentation. We report the case of a 68-year-old male with a history of head and neck squamous cell carcinoma (HNSCC) who presented with worsening nausea, abdominal pain, postprandial vomiting, and early satiety for over two months. Prior to this presentation, he was evaluated for several postauricular lumps, with computerized tomography (CT) scan showing a supraglottic mass and an excisional biopsy of a postauricular nodule confirming metastatic HNSCC. A CT scan of the chest, abdomen, and pelvis during the admission showed worsening lymphadenopathy in the mediastinum and hilar regions, as well as new ascites and peritoneal lesions. Esophagogastroduodenoscopy showed a large erythematous nodular lesion in the second portion of the duodenum occupying approximately one-third of the lumen circumference. Similar to the previously worked up nodule, histology from the duodenal mass biopsies showed metastatic poorly differentiated squamous cell carcinoma that was strongly positive for p63 and p16. Thus, we report the first case of concurrent duodenal and peritoneal metastasis from an HNSCC.

A Rare Presentation of Poorly Differentiated Lung Carcinoma with Duodenal Metastasis and Literature Review.

Lung cancer is a common malignancy which is frequently found to metastasize to distant sites including bone, liver, and adrenal glands. There are rare reports of metastases to the gastrointestinal (GI) tract, with the duodenum being the most uncommon. We present a rare case of a poorly differentiated lung carcinoma metastasizing to the duodenum. This case enhances the medical literature as it provides additional distinct features to the clinical and histological presentation of metastatic lung carcinoma to the GI tract. A 61-year-old male with a history of poorly differentiated lung carcinoma presented with worsening dizziness, fatigue, and early satiety. He had extensive workup done in the past for hemoptysis including a computerized tomography scan of the chest which showed a new lobulated, apical lesion and hilar lymphadenopathy. He ultimately had a transthoracic fine-needle aspiration (FNA) of the mass and was later diagnosed with poorly differentiated lung carcinoma. On examination, the patient was noted to be pale, tachycardic, and hypotensive. The patient was noted to have an acute drop in his hemoglobin requiring fluid resuscitation, multiple blood transfusions, and evaluation with an esophagogastroduodenoscopy. He was found to have an oozing ulcer in the third portion of the duodenum whose biopsies showed poorly differentiated carcinoma with areas of neuroendocrine differentiation, similar to his lung biopsy results, which was consistent with metastatic lung carcinoma.
