RT Journal Article T1 Locoregional Lymph Node Recurrence of Trunk Melanoma in Non-sentinel Lymph Node Basins: An Observational Retrospective Study. A1 Moro, Ruggero A1 González-Ramos, Jessica A1 Martínez-García, Silvestre A1 Requena, Celia A1 Traves, Victor A1 Manrique-Silva, Esperanza A1 Nagore, Eduardo K1 lymph node K1 recurrence K1 trunk K1 melanoma AB Locoregional lymph node recurrences of primary trunk melanoma can occur in basins not identified during sentinel lymph node biopsy. However, the factors associated with recurrences in non-sentinel lymph node basins are unknown. To evaluate these factors, this observational retrospective study examined the patterns of first lymph node recurrence and the factors associated with recurrence in non-sentinel lymph node basins. A total of 305 patients with primary trunk melanoma who had undergone sentinel lymph node biopsy from 2000 to 2015 were evaluated. Twenty-three patients presented locoregional lymph node recurrence; 8 of which (34.8%) were in non-sentinel lymph node basins. Non-sentinel lymph node recurrences were more frequent in patients with positive sentinel lymph nodes and in those patients whose number of tumour-involved nodes was > 3. These results suggest that clinical examination and ultrasound surveillance should be performed on all potential lymph node drainage basins of trunk melanomas.
