Application of sub-stage-specific PET in stage 3 melanoma enables asymptomatic detection of most recurrences, has high NPVs that may provide patient reassurance, and is associated with a high rate of detection of resectable and potentially curable disease at relapse.

The stability of markers that identify cancer cells that propagate disease is important to the outcomes of targeted therapy strategies. In human melanoma, conflicting data exist as to whether hierarchical expression of CD271/p75/NGFR (nerve growth factor receptor) marks cells with enriched tumorigenicity, which would compel their specific targeting in therapy. To test whether these discrepancies relate to differences among groups in assay approaches, we undertook side-by-side testing of published methods of patient-derived melanoma xenografting (

Aim Patients who undergo radical pelvic surgery often have problems with perineal wound healing and pelvic collections. While there is recognition of the perineal morbidity, there also remains uncertainty around the benefit of vertical rectus abdominus myocutaneous (VRAM) flaps due to the balance between primary healing and the complications associated with this form of reconstruction. This study aimed to evaluate factors associated with significant flap and donor site related complications following VRAM flap reconstruction for radical pelvic surgery.

The deep inferior epigastric artery (DIEA) distributes musculocutaneous perforators in a uniform pattern that comprises "medial row" versus "lateral row" perforators, with these two rows having anatomical and functional differences. This pattern of two perforator rows is distributed from the DIEA regardless of the number of major DIEA trunks, with there variably being one to four major trunks. As such, a single DIEA trunk will still distribute two perforator rows, as will four major DIEA trunks. What remains to be answered is how such an anatomical fact may come to be? The answer probably lies in the anatomy and embryology of the rectus abdominis muscle itself. With two muscle heads to each hemiabdominal rectus abdominis muscle present from early in its development, it is highly likely that each head of rectus abdominis muscle draws its own blood supply from its source DIEA pedicle, one "perforator row" for each head, regardless of DIEA branching pattern from which these rows are drawn, thus providing an embryological and anatomical basis for the observation of two uniform perforator rows.
