Self-Shielding Gyroscopic Radiosurgery for Uveal Melanoma: A First Case Report.

Stereotactic radiosurgery (SRS) is a well-established treatment modality for the management of uveal melanoma, achieving high tumor control and eye retention rates. There are several SRS treatment platforms available, including the recently developed self-shielding gyroscopic radiosurgery (GRS) system. We report the first use of GRS in the treatment of uveal melanoma.

Tumor Control Probability and Time-Dose-Response Modeling for Stereotactic Radiosurgery of Uveal Melanoma.

Purpose: Uveal melanoma (UM), although a rare malignancy, stands as the most prevalent intraocular malignancy in adults. Controversies persist regarding the dose dependency of local control (LC) through radiation therapy. This study sought to elucidate the significance of the prescription dose by employing time-dose-response models for patients with UM receiving photon-based stereotactic radiosurgery (SRS).

Severe Visual Impairment Following CAR T-Cell Therapy in Two Individuals with Malignant Optic Nerve Infiltration.

We report two patients who displayed evidence of localized ocular inflammation after CAR T-cell infusion. To manage the resulting severe visual impairment, systemic corticosteroids were administered to both patients. This treatment led to a reduction in local inflammation and restored vision in one of the patients.

Tumor lysis syndrome induced by tebentafusp.

Tebentafusp, a bispecific T-cell receptor fusion protein directed against gp100 and CD3, can improve survival in patients with metastatic uveal melanoma and was recently approved for the treatment of -positive uveal melanoma patients. Since tebentafusp often induces cytokine-release syndrome, doses must be escalated and patients monitored as inpatients after the first infusions. The occurrence of tumor lysis syndrome, a potentially life-threatening condition, after administration of a single dose of tebentafusp, is reported here.

Local Recurrence in Choroidal Melanomas following Robotic-Assisted Radiosurgery (CyberKnife).

Introduction: Tumor recurrence in choroidal melanoma has been associated with decreased overall survival due to metastatic spreading. To detect risk factors of local recurrence and side effects, we analyzed tumor planning and treatment parameters in patients with recurrence of choroidal melanoma after treatment with robotic-assisted radiosurgery (CyberKnife).

Methods: Six hundred ninety-four patients treated with CyberKnife between 2005 and 2019 were retrospectively reviewed.

Robotic CyberKnife Radiosurgery for the Treatment of Choroidal and Ciliary Body Melanoma.

Purpose: To present the results of robotic-assisted radiosurgery in choroidal and ciliary body melanomas treated at the Department of Ophthalmology of Ludwig-Maximilians-University and the European CyberKnife Center in Munich, Germany.

Design: Interventional case series METHODS: This retrospective study included 594 consecutive patients referred to our clinic for the treatment of choroidal and ciliary body melanomas with robotic radiosurgery (CyberKnife) from 2005 to 2019. Eye retention, local control and disease-specific survival rates were calculated as Kaplan-Meier and actuarial estimates.

Pars-plana-vitrectomy for endophthalmitis treatment and the role of standardized ultrasound.

Purpose: Endophthalmitis is a severe inflammation following surgery or endogenous spread of pathogens. Besides clinical signs and symptoms, standardized ultrasound might help to confirm the diagnosis. Thus, we analyzed 172 cases of endophthalmitis for pathogens, visual acuity (VA) and the predictive value of standardized ultrasound.

Robotic CyberKnife radiosurgery for small choroidal melanomas.

Plaque brachytherapy is the most common procedure for the treatment of small choroidal melanoma, especially in posteriorly located tumors. However, there is only little information on outcome after treatment with stereotactic radiosurgery, for example, CyberKnife radiosurgery. We reviewed patients with choroidal melanoma (maximum tumor height 4 mm) treated with CyberKnife radiosurgery.

Robotic assisted CyberKnife radiosurgery for the treatment of iris melanoma.

Iris melanoma is a rare form of uveal melanoma with potential metastic spread. Treatment options include surgical resection, enucleation or irradiation. We analysed visual outcome, complication appearance and management in eight patients with iris melanoma following robotic-assisted CyberKnife treatment.

Robotic assisted CyberKnife radiosurgery for the treatment of choroidal metastasis.

Purpose: Choroidal metastases occur in many patients with systemic cancer and limit quality of life due to visual deterioration or pain. The limited prognosis of these patients demand treatment approaches that aim at a quick response and easy application. We evaluated a robotic assisted radiosurgery device, the CyberKnife, in the treatment of choroidal metastasis.

Robotic-assisted radiosurgery for the treatment of vasoproliferative tumours.

Purpose: Vasoproliferative tumours (VPT) are a rare but benign entity that can lead to severe visual acuity deterioration. There is no standard of care, and depending on the degree of clinical features, including tumour size and dissemination, visual acuity and subretinal fluid, treatment options include observation, cryotherapy and brachytherapy. Particularly in larger tumours, brachytherapy has advantages over other options, although higher radiation doses and the need for surgical application are disadvantages of this otherwise effective treatment option.

Screening for Predictive Parameters Requiring Psycho-Oncological Intervention via the National Comprehensive Cancer Network Distress Thermometer in the Follow-Up of Uveal Melanoma Patients.

Aim: To assess a profile of uveal melanoma patients at risk of requiring active psycho-oncological intervention by employing the National Comprehensive Cancer Network (NCCN) distress thermometer.

Methods: Multivariate correlation and multiple linear regression analysis of data collected retrospectively from 106 consecutive patients suffering from uveal melanoma.

Results: Distress levels correlated with practical (p = 0.

The national comprehensive cancer network distress thermometer as a screening tool for the evaluation of quality of life in uveal melanoma patients.

Purpose: To assess quality of life (QoL) status via the National Comprehensive Cancer Network (NCCN) distress thermometer as a psychooncological screening tool in uveal melanoma patients.

Methods: One hundred and six consecutive patients suffering from uveal melanoma completed the distress thermometer between 04/2018 and 12/2018. Practical, emotional, family concerned, spiritual, physical and overall distress levels, distribution of distress and subgroup analyses defining groups of potential high distress levels in need of intervention were assessed.

Incidence of secondary glaucoma after treatment of uveal melanoma with robotic radiosurgery versus brachytherapy.

Purpose: Different modalities of radiation therapy nowadays allow for effective treatment of uveal melanoma combined with the advantage of eye preservation. However, this advantage can secondarily be impaired by radiation-related side effects. After local recurrence, secondary glaucoma (SG) has been described as second most frequent complication leading to need of enucleation.

Robotic radiosurgery for the treatment of medium and large uveal melanoma.

The aim of the study was to analyze the local efficacy and eye retention rate after frameless, image-guided robotic radiosurgery against uveal melanoma. A total of 217 patients, mostly with medium and large unilateral uveal melanomas (3% small, 62% medium, and 35% large) were treated. The median age was 64 years (range 21-95 years).

Intravitreal ranibizumab versus isovolemic hemodilution in the treatment of macular edema secondary to central retinal vein occlusion: twelve-month results of a prospective, randomized, multicenter trial.

Purpose: This is a prospective, randomized, multicenter, investigator-initiated trial to evaluate the 12-month effectiveness of isovolemic hemodilution (IH) with prompt versus deferred intravitreal injections (IVI) of ranibizumab 0.5 mg for the treatment of macular edema secondary to early central retinal vein occlusion (CRVO).

Methods: Eyes with macular edema due to CRVO having occurred not more than 8 weeks previously received either monthly ranibizumab IVI in combination with IH (group I, n = 28) or IH alone (group II, n = 30).

Quality of life in the follow-up of uveal melanoma patients after CyberKnife treatment.

To assess quality of life in uveal melanoma patients within the first and second year after CyberKnife radiosurgery. Overall, 91 uveal melanoma patients were evaluated for quality of life through the Short-form (SF-12) Health Survey at baseline and at every follow-up visit over 2 years after CyberKnife radiosurgery. Statistical analysis was carried out using SF Health Outcomes Scoring Software and included subgroup analysis of patients developing secondary glaucoma and of patients maintaining a best corrected visual acuity (BCVA) of the treated eye of 0.
