Objectives Early-phase clinical trials play a pivotal role in drug development. However, limited data are available on outcomes of gastrointestinal (GI) cancer patients enrolled in phase I clinical trials. Here, we evaluated the characteristics associated with survival in GI cancer patients participating in phase I clinical trials and attempted to validate previously established prognostic models. Materials and methods All consecutive patients with advanced GI tumors who participated in phase I clinical trials at our institution from January 2007 to December 2013 and received at least 1 dose of the study drug were included. Cox regression models were used to estimate multivariable-adjusted hazard ratio (HR) and 95% confidence interval. Results In 243 study patients (median age, 62 y [range, 26 to 82 y]; 55% male), treatment included chemotherapy only (14%), targeted therapy (41%), chemotherapy+targeted therapy (42%), and others (2%) for the following disease types: pancreatic (42%), colorectal (34%), gastroesophageal (10%), hepatobiliary (13%), and others (2%). Response rate was 4%, with 38% achieving stable disease and 42% having progressive disease. Median survival was 5.8 months (range, 0.2 to 52.4 mo). Our multivariable Cox regression analyses included the following as predictors of survival: Eastern Cooperative Oncology Group performance score ≥1 (HR=1.76), prior systemic therapies ≥2 (HR=1.63), lactate dehydrogenase >618 IU/L (HR=1.85), sodium >135 mmol/L (HR=0.46), and white blood count >6×10/L (HR=1.5). Our data set was consistent with previous prognostic scores. Conclusions This is the largest study to assess clinical outcomes in this patient population. Phase I trials provide clinical benefit to patients with advanced GI malignancies and should be recommended as a treatment option in appropriate patients.

Hepatocellular carcinoma (HCC) is a highly vascular tumor. Angiogenesis in HCC is mediated at least in part by vascular endothelial growth factor (VEGF), which is expressed in HCC and surrounding cirrhotic tissue. VEGF mediates its angiogenic effects through multiple receptors including VEGF receptor 2 (VEGFr2, KDR/FLK-1), The distribution and clinical significance of VEGFr2 expression in HCC and cirrhotic liver in the setting of liver transplantation have not been tissue site specific evaluated. Immunohistochemical staining for VEGFr2 was performed in 78 liver explants from patients with HCC undergoing liver transplantation. VEGFr2 levels in HCC were significantly increased compared to adjacent, nontumorous cirrhotic liver areas (P < 0.05). VEGFr2 levels were significantly higher in the veins and sinusoids of poorly differentiated tumors (P < 0.05). VEGFr2 levels in the tumors were not significantly different between patients within and beyond Milan criteria. However, VEGFr2 levels were significantly higher in the arteries of non-tumorous liver in patients beyond Milan criteria (P < 0.05). No significant association was observed between VEGFr2 levels and the presence of tumor vascular invasion or recurrence post transplantation. These findings suggest that VEGFr2 up-regulation is a feature of poor differentiation and tumor progression. Further investigation is needed to assess the value of angiogenesis modulation in preventing tumor formation and/or progression in cirrhotic patients.

PURPOSE To describe a case of uveal metastasis secondary to hepatocellular carcinoma. METHODS The authors present a 57-year-old man with known diagnosis of hepatocellular carcinoma, with progressive visual problems in his right eye. Work-up including indirect ophthalmoscopic examination, ocular ultrasonography, and brain magnetic resonance imaging revealed a dome-shaped choroidal mass abutting the optic disk with surrounding shallow exudative retinal detachment. RESULTS A fine-needle biopsy of the lesion confirmed the presence of malignant cells suggestive of metastatic disease from hepatocellular carcinoma. The patient was subsequently treated with brachytherapy. The patient died 3 weeks after the treatment due to pneumonia, which was felt to be unrelated to his ocular disease. CONCLUSION This is a report of a very unusual case of hepatocellular carcinoma with metastasis to uveal tract.
