Brachytherapy in the prevention of recurrence of conjunctival melanoma : Results of a case report in a University Hospital in Valladolid, Spain. Strahlenther Onkol 2023; 199:1025-1030. [PMID: 37280383 DOI: 10.1007/s00066-023-02094-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 04/26/2023] [Indexed: 06/08/2023]
Abstract
AIM Describe the results of brachytherapy in the prevention of recurrences in conjunctival melanoma (CM) and describe a dosimetric protocol. METHODS Retrospective and descriptive case report. Eleven consecutive patients with a confirmed histopathological diagnosis of CM treated with brachytherapy between 1992 and 2023 were reviewed. Demographic, clinical, and dosimetric characteristics as well as recurrences were recorded. Quantitative variables were represented by the mean, median, and standard deviation, and qualitative variables by frequency of distribution. RESULTS Of a total of 27 patients diagnosed with CM, 11 who were treated with brachytherapy were included in the study (7 female; mean age at time of treatment: 59.4 years). Mean follow-up was 58.82 months (range 11-141 months). Of a total of 11 patients, 8 were treated with ruthenium-106 and 3 with iodine-125. Brachytherapy was performed in 6 patients as adjuvant therapy after biopsy-proven CM on histopathology and in the other 5 patients after recurrence. The mean dose was 85 Gy in all cases. Recurrences outside of the previously irradiated area were observed in 3 patients, metastases were diagnosed in 2 patients, and one case of an ocular adverse event was reported. CONCLUSION Brachytherapy is an adjuvant treatment option in invasive conjunctival melanoma. In our case report, only one patient had an adverse effect. However, this topic requires further research. Furthermore, each case is unique and should be evaluated by experts in a multidisciplinary approach involving ophthalmologists, radiation oncologists, and physicists.

Abstract
Primary acquired melanosis (PAM) is acquired conjunctival pigmentation that can give rise to conjunctival melanoma (CM), a malignant tumor of the bulbar and palpebral conjunctiva or the caruncle. Surgical excision is the treatment of choice for this neoplasm. Topical chemotherapy is also used for patients with PAM with atypia or CM, hand in patients with recurrent or extensive disease, this may be an important option. Of the several chemotherapeutic drugs used, topical interferon alpha 2b (IFN-α2b) has become popular because of its low toxicity. Clinical evidence from case reports and case series supports the efficacy of IFN-α2b as the preferred adjuvant treatment for PAM and CM. In addition, topical IFN-α2b has been successfully applied to melanocytic tumors refractory to other treatments, such as cryotherapy and topical mitomycin C. In patients with locally advanced CM, the combination of IFN-α2b and systemic immunotherapy may serve as an alternative to exenteration. Given the low frequency of CM, long-term multicenter studies are needed to demonstrate the efficacy of IFN-α2b for preventing local recurrence and distant metastasis.

Abstract
BACKGROUND To relate conjunctival melanoma characteristics to local control. METHODS Retrospective, registry-based interventional study with data gathered from 10 ophthalmic oncology centres from 9 countries on 4 continents. Conjunctival melanoma patients diagnosed between January 2001 and December 2013 were enrolled in the study. Primary treatments included local excision, excision with cryotherapy and exenteration. Adjuvant treatments included topical chemotherapy, brachytherapy, proton and external beam radiotherapy (EBRT). Cumulative 5-year and 10-year Kaplan-Meier local recurrence rates were related to clinical and pathological T-categories of the eighth edition of the American Joint Committee on Cancer (AJCC) staging system. RESULTS 288 patients had a mean initial age of 59.7±16.8 years. Clinical T-categories (cT) were cT1 (n=218,75.7%), cT2 (n=34, 11.8%), cT3 (n=15, 5.2%), cTx (n=21,7.3%) with no cT4. Primary treatment included local excision (n=161/288, 55.9%) followed by excision biopsy with cryotherapy (n=108/288, 37.5%) and exenteration (n=5/288, 1.7%). Adjuvant therapies included topical mitomycin (n=107/288, 37.1%), plaque-brachytherapy (n=55/288, 19.1%), proton-beam (n=36/288, 13.5%), topical interferon (n=20/288, 6.9%) and EBRT (n=15/288, 5.2%). Secondary exenteration was performed (n=11/283, 3.9%). Local recurrence was noted in 19.1% (median=3.6 years). Cumulative local recurrence was 5.4% (3.2-8.9%), 19.3% (14.4-25.5%) and 36.9% (26.5-49.9%) at 1, 5 and 10 years, respectively. cT3 and cT2 tumors were twice as likely to recur than cT1 tumours, but only cT3 had statistically significantly greater risk of local recurrence than T1 (p=0.013). Factors such as tumour ulceration, plica or caruncle involvement and tumour thickness were not significantly associated with an increased risk of local recurrence. CONCLUSION This multicentre international study showed that eighth edition of AJCC tumour staging was related to the risk of local recurrence of conjunctival melanoma after treatment. The 10-year cumulative local recurrence remains high despite current management.

Eye (Lond) 2021; 35:3410-3418. [PMID: 33608640 DOI: 10.1038/s41433-021-01454-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 01/09/2021] [Accepted: 01/29/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Growing evidence supports an individualised approach rather than radical surgery for conjunctival melanoma (CM). This study aimed to compare the long-term outcome between individualised and conventional exenteration techniques. METHODS Our study retrospectively recruited advanced CM (clinical T3 stage) patients treated with individualised (13 cases) or conventional (18 cases) exenteration from June 2014 to April 2019. The individualised approach preserved at least three quadrants of the orbit, and the conventional procedures removed at least one third of the orbital tissues. The medical records were collected and analyzed during April 2020, including demographics, tumour characteristics, surgical details, postoperative rehabilitation and tumour-related prognosis. RESULTS The tumour basal diameter was statistically (P = 0.011) larger in the conventional group (23.3 ± 7.6 mm) than in the individualised group (15.4 ± 6.3 mm). More tissues were preserved in the individualised group, resulting in a shorter duration of wound healing (2.1 ± 0.6 vs. 3.6 ± 2.0 weeks, P = 0.018) and less incidence of hollow appearance (15% vs. 72%, P = 0.003) than the conventional group. After follow-up for 39.3 ± 17.3 months, a comparison of survival curves showed no significant differences (P = 0.638) between the two groups. The 1- and 2-year overall survival rates were estimated as 100% and 80.0% in the individualised group, and 93.8% and 72.5% in the conventional group, respectively. Low or mixed pigmentation was identified as the risk factor for tumour-related mortality based on multivariate regression analysis. CONCLUSIONS The individualised approach to exenteration offers improved aesthetic results while still maximises the curable chance for advanced CM.

Conjunctival Melanoma: Outcomes Based on Age at Presentation in 629 Patients at a Single Ocular Oncology Center. Cornea 2020; 40:554-563. [PMID: 32740010 DOI: 10.1097/ico.0000000000002449] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 06/03/2020] [Indexed: 11/27/2022]
Abstract
PURPOSE To investigate the clinical features and outcomes for conjunctival melanoma based on patient age. METHODS A retrospective review of patients with conjunctival melanoma managed at a single tertiary referral center from April 18, 1974, to September 9, 2019. Clinical features and outcomes were compared by patient age category at presentation (young ≤45 years, middle-aged 46-69 years, and older ≥70 years), with Kaplan-Meier and Cox proportional hazard analysis [hazard ratio (95% confidence interval)]. RESULTS There were 629 patients categorized as young in 130 (21%), middle-aged in 278 (44%), and older in 221 (35%). A comparison by age category (young vs. middle-aged vs. older) revealed that older patients had melanoma with greater number of affected quadrants (1.7 vs. 1.8 vs. 2.0, P = 0.001) and clock hours (3.9 vs. 4.2 vs. 5.2, P = 0.001). All patients were treated with surgical excision, with no difference in requirement for additional medical or radiation therapy. By 10-year Kaplan-Meier outcomes, older patients had more frequent visual acuity loss ≥3 lines (11% vs. 28% vs. 64%, P < 0.001) and local tumor recurrence (38% vs. 46% vs. 70%, P < 0.001). Hazard ratio for the oldest age group (age ≥70) revealed a 7.76-fold (3.33-18.09) increased risk for visual acuity loss (P < 0.001), and a 2.08-fold (1.32-3.28) increased risk of local tumor recurrence (P = 0.002). There was no difference by age in risk for enucleation, exenteration, locoregional lymph node involvement, distant systemic metastasis, or death. CONCLUSIONS Older patients with conjunctival melanoma present with more extensive disease and have increased risk for visual acuity loss and local tumor recurrence.
