ReviewMethods to reduce postoperative surgical site infections after head and neck oncology surgery.
Head and neck cancer surgery is often a complex multi-step procedure that includes major resections, vascularised tissue reconstruction, and extensive neck dissection. The upper aerodigestive tract mucosal lining is often disrupted during surgery, which requires the management of a clean-contaminated field and the need to reconstruct the mucosal lining. With bacterial contamination, surgical site infections (SSI) are a serious complication that can result in delayed wound healing, wound breakdown, fistula formation, and compromised tissue reconstruction. ⋯ In this Review, we outline the data supporting perioperative antibiotic prophylaxis for clean-contaminated surgeries, which suggest that clindamycin is an inadequate prophylactic antibiotic therapy in the reduction of SSI, and that prolonged antibiotic courses have no established benefit. For salvage laryngectomy after radiotherapy with or without chemotherapy, reconstruction with vascularised tissue reduces the frequency and severity of pharyngocutaneous fistula formation. These evidence-based recommendations have been shown to reduce the chance of SSI after head and neck surgery.

Delivery of meaningful cancer care: a retrospective cohort study assessing cost and benefit with the ASCO and ESMO frameworks.
The American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology (ESMO) have developed frameworks that quantify survival gains in light of toxicity and quality of life to assess the benefits of cancer therapies. We applied these frameworks to a cohort of contemporary randomised controlled trials to explore agreement between the two approaches and to assess the relation between treatment benefit and cost. ⋯ None.

ReviewRadiotherapy in patients with HIV: current issues and review of the literature.
Although the introduction of highly active antiretroviral therapy has radically improved the life expectancy of patients with HIV, HIV positivity is still considered a major barrier to oncological treatment for patients with cancer because of their worse prognosis and increased susceptibility to toxic effects compared with patients who are immunocompetent. The use of radiotherapy with or without chemotherapy, immunotherapy, or molecular targeted therapy is the standard of care for several cancers. ⋯ In this Review, we discuss the role of radiotherapy, with or without chemotherapy or new drugs, in the treatment of cancer in patients with HIV, with a focus on the efficacy and tolerability of this approach on the basis of available evidence. Moreover, we analyse and discuss the biological basis of interactions between HIV and radiotherapy, evidence from preclinical studies, and immunomodulation by radiotherapy in the HIV setting.
