Patterns of care and survival outcomes after treatment for uveal melanoma in the post-coms era (2004-2013): a surveillance, epidemiology, and end results analysis.

Patterns of care and survival outcomes after treatment for uveal melanoma in the post-coms era (2004-2013): a surveillance, epidemiology, and end results analysis. J Contemp Brachytherapy. 2017 Oct;9(5):453-465 Authors: Rao YJ, Sein J, Badiyan S, Schwarz JK, DeWees T, Grigsby P, Rao PK Abstract Purpose: The Collaborative Ocular Melanoma Study (COMS) established modern treatment recommendations for uveal melanoma. We aim to evaluate patterns of care and survival outcomes in the time after COMS. Material and methods: The retrospective study population includes 2,611 patients in the SEER database treated for uveal melanoma between 2004-2013. Patients stage were T1-4N0M0. Data analyzed included age, clinical stage, tumor size, race, and treatment. Treatments included enucleation (EN) and globe preserving therapy (GPT), which consisted of limited surgical resection or ablation (LSRA), external beam radiation (EBRT), or brachytherapy (BT). Patients treated with radiation may receive radiation therapy alone (RTA) or radiation therapy and supplemental laser therapy (RT+SLT). We evaluated disease specific survival (DSS) and overall survival (OS) using log-rank statistics, and Cox univariate and multivariate analysis. Results: The median follow-up was 44 months. Treatment strategy was EN in 538 (20.6%) patients, LSRA in 80 (3.1%), EBRT in 609 (23.3%), and BT in 1,384 (53.0%). 1,876 patients received RTA and 117 received RT+SLT. Enucleation was associated wi...

CONCLUSION: We report a severe adverse event from pembrolizumab therapy resulting in uveitis and persistent hypotony. Repeat injections of high viscosity OVD achieved an increase in IOP up to 12 months. This technique may be a useful adjuvant or alternative to PPV and SO.

After brachytherapy, some choroidal melanomas regress faster than others. Several studies suggest that these tumors are more likely to metastasize than those that regress slowly. Not all authors support this view, some reporting no correlation between tumor regression and monosomy 3, which is highly lethal.1 More research is needed to determine whether tumor regression rate after brachytherapy predicts metastasis.

G-protein-coupled receptors (GPCRs) comprise a large family of cell-surface receptors that transduce signals through interaction with heterotrimeric G-protein subunits (G α, Gβ, and Gy). The aberrant expression, overexpression or signal reprogramming of GPCRs and G-proteins have been linked to cancer initiation, tumor cell growth, metastasis and angiogenesis. Frequent somatic mutations of Gnaq and Gna11 were found in uveal melanomas of humans thereby identifying th ese G-proteins as potential oncogenes in human neoplasia.

In choroidal melanoma the radiation threshold dose for local control remains largely unknown. The present study examined a group of patients that received a wide range of minimum tumor dose in order to investigate a dose-response relationship. A literature review is performed to compare our results with available evidence in brachytherapy and charged particle external beam radiotherapy.

CONCLUSION: PBRT for intraocular tumors can induce various orbital and periorbital tissue changes. More specifically, when enucleation is performed after PBRT due to disease progression, significant enophthalmos and OV decrease can develop and can cause poor facial cosmesis as treatment sequelae.

Abstract Uveal melanoma (UM) is the most common primary intraocular tumor in adults, which has high frequency of metastasis to the liver, typically causing a fatal outcome. Chemo-resistance remains a major obstacle in the therapeutic approach to UM, leaving limited choice for treating UM. Other possible treatments have been explored but the results are yet to be evident. To improve therapy for UM, transcriptional suicide genes were transfected into the OCM-1 cell line. In the current study, OCM-1 cells transfected with lentiviral-meditated EGFP, cytosine deaminase (CD)/EGFP, and VP22-CD/EGFP were established. ...
