COMBI-I: Long-Term Overall Survival With Spartalizumab Plus Dabrafenib and Trametinib in BRAF V600-Mutant Advanced Melanoma.

The COMBI-I trial (ClinicalTrials.gov identifier: NCT02967692) evaluating spartalizumab plus dabrafenib and trametinib (sparta-DabTram, n = 267) versus placebo plus dabrafenib and trametinib (placebo-DabTram, n = 265) for BRAF V600-mutant unresectable or metastatic melanoma failed to reach its primary end point of progression-free survival at 24 months. This final analysis reports overall survival (OS) during at least 5 years of extended follow-up. At the end of the trial (August 21, 2024), the median duration of follow-up was 76.9 months (range, 73.7-83.3 months). The median OS was 61.5 months (95% CI, 41.6 to not evaluable) for the sparta-DabTram arm and 41.6 months (95% CI, 30.6 to 56.9) for the placebo-DabTram arm (hazard ratio, 0.760 [95% CI, 0.598 to 0.966]). The safety findings were consistent with the known safety profile for sparta-DabTram. The most common treatment-related adverse event (TRAE) was pyrexia (65.9% v 46.2%, respectively, in the two study arms). Grade ≥3 TRAEs were reported in 57.3% and 36.7% of patients in the two arms, respectively. The combination of sparta-DabTram appears to improve OS compared with dabrafenib and trametinib alone in patients with BRAF V600-mutant metastatic melanoma.

Years of life lost in patients with a false-negative diagnosis of primary melanoma. A prospective study of the German Central Malignant Melanoma Registry involving 9063 patients over 28 years.

A false-negative diagnosis of cancer can lead to a delay in effective treatment and a poorer prognosis. Here, we use the example of cutaneous melanoma to examine how many years of life are lost after a false-negative diagnosis compared to a primarily correct diagnosis. From 1996 to 2015, 9,063 patients are prospectively registered in the German Central Malignant Melanoma Registry and followed up until December 2023. A false-negative diagnosis is found in 206 (2.3%) patients. The median time to correct diagnosis is 24.0 months. The 10-year recurrence-free survival probabilities are 32.9% for false-negative diagnoses and 76.2% for correct diagnoses (p < 0.001). The 10-year melanoma-specific survival probabilities are 62.1% versus 85.0% (p < 0.001). On average, each person with an initial false-negative diagnosis loses 8.2 years of life compared to people with a correct diagnosis. This high number of years of life lost raises the question of whether similar results also apply to other types of cancer.
