RESUMO

Background: The significance of a family history of esophageal adenocarcinoma in the progression to esophageal adenocarcinoma in patients with Barrett's esophagus has not been thoroughly evaluated. The purpose of this study is to evaluate the presence of esophageal adenocarcinoma in a first-degree relative in patients with Barrett's esophagus. Methods: A retrospective cohort study was conducted of patients with Barrett's esophagus at a tertiary care center undergoing radiofrequency ablation. Family history, demographics, and pathology and endoscopy reports were assessed in all patients. Findings: Three hundred and one patients with Barrett's esophagus were assessed. Nineteen patients who had a diagnosis of esophageal adenocarcinoma on index endoscopy were excluded. Nineteen (6.7%) patients had a first-degree relative with esophageal adenocarcinoma. Four (21.1%) of these patients progressed to esophageal adenocarcinoma. Of patients without first-degree relative with esophageal adenocarcinoma 22/263 (8.7%) progressed to esophageal adenocarcinoma. In a logistic regression model adjusted for sex and the number of radiofrequency ablation treatments, we found that family history of esophageal adenocarcinoma was a significant independent predictor of progression to esophageal adenocarcinoma (odds ratio = 5.55, 95% confidence interval: 1.47-20.0). Conclusion: Our study indicates that Barrett's esophagus patients with a first-degree family member with esophageal adenocarcinoma are at 5.5-fold higher risk for disease progression to esophageal adenocarcinoma. Family history of esophageal adenocarcinoma in Barrett's esophagus patients should be considered in patient surveillance and radiofrequency ablation treatment, beyond recommended guidelines.

RESUMO

Metastatic disease to the stomach or duodenum is an infrequent diagnosis, and head and neck squamous cell carcinoma (HNSCC) is one of the least common primary malignancies that lead to gastric or duodenal metastases. We report the case of a 65-year-old man with human immunodeficiency virus infection and previously diagnosed HNSCC who presented with melena. The patient had a percutaneous endoscopic gastrostomy tube placed 3 months prior to his presentation. Laboratory testing was significant for normocytic anemia and a digital rectal examination was positive for melena. Esophagogastroduodenoscopy revealed numerous cratered nodules with contact bleeding in the stomach as well as the duodenum that appeared malignant. Biopsies of the gastric and duodenal nodules were positive for p40 and CK 5/6, consistent with metastatic squamous cell carcinoma.

RESUMO

PURPOSE: To determine the personalized rate of uveal melanoma-related metastasis on the basis of individual tumor cytogenetic profile. DESIGN: Retrospective case series. PARTICIPANTS: A total of 1059 patients with uveal melanoma. METHODS: Fine-needle aspiration biopsy (FNAB) for DNA amplification and whole genome array-based assay were performed for analysis of chromosomes 3, 6, and 8. MAIN OUTCOME MEASURES: Melanoma-related metastasis. RESULTS: The mean patient age was 57 years, and most were white (1026/1059, 97%). The melanoma involved the choroid (938/1059, 89%), ciliary body (85/1059, 8%), or iris (36/1059, 3%), with 19% being macular in location. The mean largest basal diameter was 11 mm (median, 12 mm; range, 3-24 mm), and mean thickness was 5 mm (median, 4 mm; range, 1-20 mm). On the basis of individual chromosomal mutations, risk for metastasis was increased for chromosome 3 partial monosomy (hazard ratio [HR], 2.84; P = 0.001), 3 complete monosomy (HR, 6.7, P < 0.001), 6q loss (HR, 3.1, P = 0.003), 8p loss (HR, 21.5, P < 0.001), and 8q gain (HR, 9.8, P < 0.001). Kaplan-Meier estimate for melanoma-related metastasis in 1, 3, 5, and 7 years for 3 partial monosomy was 1%, 5%, 14%, and 17%; for 3 complete monosomy was 3%, 19%, 28%, and 37%; for 6q loss was 8%, 23%, 49%, and 49%; for 8p loss was 8%, 29%, not estimable (NE), and NE; and for 8q gain was 6%, 21%, 35%, 48%, respectively. On the basis of personalized cytogenetic profiles, Kaplan-Meier estimates (1, 3, and 5 years) for melanoma-related metastasis for 3, 6, and 8 disomy (1%, 1%, 4% [HR, 1]) were low compared with the higher-risk combinations of 3 complete monosomy, 6p gain, and 8q gain (0%, 29%, 29% [HR, 10.6, P = 0.02]); 3 complete monosomy, 6 disomy, 8q gain, and 8p gain (14%, 14%, NE [HR, 18.3, P = 0.02]); 3 complete monosomy, 6 disomy, and 8q gain (8%, 27%, 39% [HR, 19.5, P < 0.001]); and 3 complete monosomy, 6 disomy, 8q gain, and 8p loss (3%, 28%, NE [HR, 31.6, P < 0.001]), respectively. CONCLUSIONS: Risk for melanoma-related metastasis strongly correlates with personalized cytogenetic profiles, with 5-year Kaplan-Meier estimates ranging from 4% with chromosomes 3, 6, and 8 disomy up to 39% for 3 complete monosomy, 6 disomy, and 8q gain.

RESUMO

PURPOSE: We explored differences in changes in medical student empathy in the third year of medical school between volunteers at JeffHOPE, a multisite medical student-run free clinic of Sidney Kimmel Medical College (SKMC), and nonvolunteers. METHOD: Volunteerism and leadership experience at JeffHOPE were documented for medical students in the Class of 2015 (n = 272) across their medical educations. Students completed the Jefferson Scale of Empathy at the beginning of medical school and at the end of the third year. Students who reported participation in other Jefferson-affiliated clinics (n = 44) were excluded from this study. Complete data were available for 188 SKMC students. RESULTS: Forty-five percent of students (n = 85) volunteered at JeffHOPE at least once during their medical educations. Fifteen percent of students (n = 48) were selected for leadership positions involving weekly clinic participation. Nonvolunteers demonstrated significant decline in empathy in medical school ( P = 0.009), while those who volunteered at JeffHOPE at least once over the course of their medical educations did not show any significant decline ( P = 0.07). CONCLUSIONS: These findings suggest that medical students may benefit from volunteering at student-run free clinics to care for underserved populations throughout medical school.

RESUMO

PURPOSE: To describe a tiny subclinical choroidal melanoma visualized only with enhanced depth imaging optical coherence tomography in a newly symptomatic patient with known oculodermal melanocytosis. METHODS: Case report. RESULTS: A 52-year-old white man with heterochromia and known oculodermal melanocytosis of the right eye, followed for 2 years without change, developed blurred vision and was referred for possible central serous chorioretinopathy. On examination, visual acuity was 20/20 in each eye. There was oculodermal melanocytosis in the right eye involving the periocular skin, episclera, iris, and choroid. On ophthalmoscopy and ocular ultrasonography, there was no appreciable mass, but subtle subfoveal fluid and perifoveal orange pigment were detected, as well as equatorial drusen. Enhanced depth imaging optical coherence tomography demonstrated a subtle optically dense focal choroidal mass measuring 4.5 mm in basal dimension and 0.7 mm in enhanced depth imaging optical coherence tomography thickness. There was choroidal vascular compression, obliteration of choroidal details, and related overlying subretinal fluid with shaggy photoreceptors, consistent with early choroidal melanoma in an eye with oculodermal melanocytosis. The patient elected early treatment considering the risk factors for growth and the risk for metastasis associated with melanoma in the setting of oculodermal melanocytosis. Plaque radiotherapy was performed with complete tumor regression clinically and by enhanced depth imaging optical coherence tomography. At 2-year follow-up, visual acuity remains 20/20, with regressed tumor and no systemic metastasis. CONCLUSION: Enhanced depth imaging optical coherence tomography is a useful tool in the evaluation of eyes with oculodermal melanocytosis, permitting high-resolution visualization of the choroid and detection of submillimeter early melanoma that might not be apparent with indirect ophthalmoscopy or ultrasonography.
