Radiofrequency ablation (RFA) is a recently developed treatment for hepatocellular carcinoma (HCC). Thus far, the prognostic impact of tumor biomarkers has not been evaluated in this treatment. High serum level of vascular endothelial growth factor (VEGF) has been shown to predict microscopic vascular invasion and metastasis in HCC. This study investigated the prognostic significance of pre-treatment serum VEGF level in patients with HCC undergoing RFA treatment. ⋯ High pre-treatment serum VEGF levels predict poor prognosis after RFA of HCC. This study highlights the importance of tumor biomarker as a prognostic predictor in ablative therapy for HCC, which has an intrinsic problem of unavailability of histopathological prognostic features.

Variations in arm lymphatic drainage put the arm lymphatics at risk for disruption during axillary lymph node surgery. Mapping the drainage of the arm with blue dye (axillary reverse mapping, ARM) decreases the likelihood of disruption of lymphatics and subsequent lymphedema. ⋯ ARM identified significant lymphatic variations draining the upper extremities and facilitated preservation in all but one case. ARM added to present-day ALND and SLNB further defines the axilla and may be useful to prevent lymphedema.

Treatment of locally advanced rectal carcinoma (LARC) often involves exenterative surgery, which can be associated with high perioperative morbidity and mortality. To assist in patient selection for radical surgery, we sought to determine clinicopathologic factors influencing recurrence and disease-free survival (DFS) of LARC. ⋯ The complication rates for pelvic exenteration remain high, but the morbidity can typically be managed without a clinically important increase in hospitalization. In primary LARC, an aggressive surgical approach provides most patients 5-year DFS. Select patients with recurrent LARC will also benefit from pelvic exenteration.

Most surgical training programs have no curriculum to teach palliative care. Programs designed for nonsurgical specialties often do not meet the unique needs of surgeons. With 80-hour workweek limitations on in-hospital teaching, new methods are needed to efficiently teach surgical residents about these problems. ⋯ With a reasonable time commitment, surgical residents are capable of learning about palliative and end-of-life care. Surgical residents think that understanding palliative care is a useful part of their training, a sentiment that is still evident 3 months later.

Wide surgical excision, lymph node dissection, and radiotherapy have been used with varying efficacy in the management of early-stage Merkel cell carcinoma. ⋯ Adjuvant radiotherapy to the primary site after surgical excision is recommended in early-stage disease. Involved regional lymph nodes should be treated with radiotherapy with or without lymphadenectomy.
