Abstract
INTRODUCTION Follow-up guidelines for melanoma greatly differ in the methods of screening for recurrence, and timing and duration of the follow up, with many areas of controversy and a lack of general consensus. The aims of this study are to present our protocol and case series for follow up and to summarize and discuss current literature on melanoma follow-up guidelines/recommendations in different countries. METHODS We retrospectively reviewed 539 patients operated for melanoma between 2004 and 2013 at the same Institution. Data on the diagnostic role of the different clinical and instrumental detection methods were adjusted for sex, age at diagnosis, staging and evaluated by Fisher's exact test and multivariate analysis. Recommendations from the literature were summarized and discussed. RESULTS Local recurrences and second melanoma were always identified through physical examination, irrespectively of melanoma staging. Regional metastases were most often identified through physical examination and ultrasound, being more frequent in stage II and III, while distant metastases were most often identified through CT scans. Surveillance follow-up schedules vary significantly depending on country, physician specialty, and stage of disease, with a lack of evidence on the efficacy of the different schemes. Similarities and controversies in the different follow-up protocols are presented and discussed. CONCLUSION Our clinical series showed that physical examination is very powerful in identifying local recurrences and second melanomas. Physical examination and ultrasound are equally powerful in identifying regional metastases, and alternating them over time could allow to reduce the number of follow-up visits. CT scans, differently from chest x-ray, showed a high power in identifying distant metastases. Surveillance follow-up schedules in the literature vary significantly depending on country, physician specialty, and stage of disease, with a lack of evidence on the efficacy of the different schemes. Standard protocols are desirable for a better evaluation of results.

Abstract
INTRODUCTION Early detection of melanoma is instrumental as the 5-year survival decreases from 93.3% to <50% when metastases are present.1-3 Distinguishing which patients require closer follow-up can be difficult for melanoma patients. Developments by Castle Biosciences' (Friendswood, TX) DecisionDx-Melanoma (DDx-M) use 31 melanoma associated genes to stratify melanomas into 4 classes with 1A having lowest risk of morbidity and mortality and 2B the highest.5 We assessed the benefit of providing additional 18FDG-PET-CT and brain MRI to genetically high-risk patients who may have otherwise been overlooked. METHODS 297 patients at our institution had biopsies sent for DDx-M between 2014 and 2021. Patients found to have Class 2 melanomas received additional screening with yearly 18FDG-PET-CT scans and brain MRIs. Patients with Class 2 DDx-M scores and negative SLNB were included in the study. 66 met inclusion criteria and received imaging. RESULTS Within 3 years of follow-up, 8/66 (12.1%) patients had metastases detected by 18FDG-PET-CT scans. No patients with stage IA or IB went on to develop metastases. DISCUSSION 18FDG-PET-CT scans detect metastases in < 3% of the time when all stage I and II patients are scanned; however, by using DDx-M in our screening protocols, we achieved a detection rate of 12.1%.6,7 These patients went on to receive treatment and would have otherwise progressed undetected, leading to higher morbidity and mortality. CONCLUSION We suggest all patients with initial stage II or above melanomas receive a DDx-M score and those with class 2 receive yearly 18FDG-PET-CT/brain MRI imaging.

J Surg Oncol 2022; 125:1312-1317. [PMID: 35262187 DOI: 10.1002/jso.26846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 02/16/2022] [Accepted: 02/22/2022] [Indexed: 11/11/2022]
Abstract
BACKGROUND The yield of baseline imaging in patients presenting with higher risk primary tumours, at least American Joint Committee on Cancer 8th edition stage IIC or III melanoma, is unclear. METHODS This retrospective study included patients referred to the Victorian Melanoma Service from January 2017 to April 2020, diagnosed with at least stage IIC or stage III melanoma. Patients with a T4b tumour and no sentinel lymph node biopsy were included as 'T4bNX'. RESULTS One hundred and sixty-four patients (median age 65 years) with baseline imaging (T4bNX: 19, IIC: 30, IIIA: 21, IIIB: 43, IIIC: 50, IIID: 1) were included. The majority were male (73%), and those with T4bNX melanoma tended to be older (median age 79 years). Distant metastases were detected in 21% (4/19) of T4bNX, 3% (1/30) of stage IIC, 0% (0/21) of stage IIIA, and 6% (6/94) of stages IIIB-D melanoma patients. All stage III patients with distant metastases had palpable lymphadenopathy a presentation. Two patients had brain metastases, both of whom had T4bNX melanoma and synchronous extra-cranial metastases. CONCLUSIONS Compared to stage IIC, baseline imaging detects higher rates of extra-cranial distant disease in stages IIIB-D and T4bNX melanoma. Intracranial imaging has greater yield in patients with distant extra-cranial disease.
