Heritable defects in telomere and mitotic function selectively predispose to sarcomas.

Cancer genetics has to date focused on epithelial malignancies, identifying multiple histotype-specific pathways underlying cancer susceptibility. Sarcomas are rare malignancies predominantly derived from embryonic mesoderm. To identify pathways specific to mesenchymal cancers, we performed whole-genome germline sequencing on 1644 sporadic cases and 3205 matched healthy elderly controls.

Negative Sentinel Lymph Node Biopsy in Patients with Melanoma: The Patient's Perspective.

Background: The majority of patients undergoing sentinel lymph node biopsy (SLNB) for melanoma will have a negative SLN. The long-term sequelae of a negative result are important when discussing this staging investigation with patients. The objective of this study was to assess rates of lymphoedema and quality of life for these patients.
