- Original description
This multicenter, phase III randomized controlled trial evaluates whether omitting re-excision after complete primary excision of cutaneous melanoma affects patient outcomes. A total of 1,749 patients with pT1b-pT4b cutaneous melanoma without evidence of metastases will be randomized to either standard re-excision according to current guidelines or no re-excision. Sentinel lymph node biopsy and adjuvant systemic therapy will be performed as indicated in both groups.Read full original descriptionShow less
Multicenter Phase 3 Randomized Controlled Trial of NO Re-excision MelanomA - NORMA 2
This multicenter, phase III randomized controlled trial evaluates whether omitting re-excision after complete primary excision of cutaneous melanoma affects patient outcomes. A total of 1,749 patients with pT1b-pT4b cutaneous melanoma without evidence of metastases will be randomized to either standard re-excision according to current guidelines or no re-excision. Sentinel lymph node biopsy and adjuvant systemic therapy will be performed as indicated in both groups.
The primary objective is to compare relapse-free survival (RFS) between the two groups. Secondary objectives include comparisons of overall survival (OS), local recurrence rates, recurrence of in-transit and lymph node metastases, distant metastasis-free survival (DMFS), surgical morbidity, quality of life, and health economic outcomes.
Inclusion: Patients must be 18 years or older at time of consent; Patients must have an ECOG performance score between 0 and 2; Histologically confirmed, stage pT1b - pT4b (TNM AJCC 8th edition) cutaneous primary melanoma; Histological subtypes that are eligible are:; Superficial Spreading Melanoma (SSM); Nodular Melanoma (NM); The primary melanoma must have been removed by diagnostic excision and must have at least a minimum of 1 mm tumor free margin for invasive melanoma AND any in situ melanoma; Patient must provide informed consent and comply with the treatment protocol and follow-up plan; Life expectancy of at least 5 years from the time of diagnosis, not considering the melanoma in question, as determined by the investigator; A survivor of prior cancer is eligible provided that ALL of the following criteria are met and documented:; The patient has undergone potentially curative therapy for all prior malignancies; Life expectancy should be at least 5 years and; The patient is deemed by their treating physician to be at low risk of recurrence from previous malignancies.
Exclusion: History of previous or concurrent (i.e., second primary) invasive melanoma; Patient has undergone surgery on a separate occasion to clear the lymph nodes of the probable draining lymphatic field, except for previous SLNB; Lentigo malignant melanoma (LMM); Spitz melanoma/malignant Spitz tumor melanoma; Uncertain diagnosis of melanoma i.e. so-called 'melanocytic lesions of unknown malignant potential' (MELTUMP or STUMP); Any additional solid tumor or hematologic malignancy during the past 5 years with a life expectancy of less than 5 years; History of organ transplantation; Non-cutaneous melanoma (uveal, mucosal); Acral melanoma; Desmoplastic melanoma; Neurotropic melanoma; Satellites, in-transit melanomas or macroscopic melanoma metastases; Other non-SSM or NM subtypes; Melanoma removed by shave excision, excogliation or core biopsy; Patient has already undergone a local flap reconstruction of the defect after excision of the primary; Multiple melanomas.
