Human myiasis is a parasitosis usually found in tropical and underdeveloped countries. It usually affects ulcerated lesions or devitalized tissues, developing after deposition of dipterous eggs. Patients with head and neck cancer are at risk to develop secondary myiasis. A representative percentage of those patients manifest with neglected and advanced tumors, usually in exposed areas and with necrotic tissues. Few case reports and small series constitute the available information about this parasitosis. Most studies have been conducted in patients with skin carcinomas, although myiasis has already been described in association with other head and neck malignancies. The authors present a series of 12 cases of myiasis secondary to head and neck cancer in addition to a literature review.

Background: Vitamin D has several roles, namely physiological function of calcium and bone metabolism, cell growth and differentiation, immune and cardiovascular function. Vitamin D deficiency can cause the risk of cancer. Head and neck cancer is one of the cancers that occur due to vitamin D deficiency in the body. This literature review was to asses and evaluate the impact and benefits of vitamin D supplementation for head and neck cancer.Discussion: A study found an association between vitamin D supplementation and a low risk of recurrence in conditions of high total vitamin D levels. Another study found a significant increase in quality of life (QOL). The primary mechanism of vitamin D action is mediated through binding of either 1,25(OH)2D3 (active form) or 25(OH)D (less active form) to the VDR, which is a member of the nuclear receptor superfamily of steroid and thyroid hormones with gene-regulatory and consequent anti-proliferative properties.Conclusions: Vitamin D supplementation provides a role in improving the condition of patients with head and neck cancer. Both in terms of suppressing recurrence and in terms of increasing quality of life

Objetivo: Sintetizar o conhecimento de estudos primários que investigaram a experiência da radioterapia, na perspectiva do paciente com câncer de cabeça e pescoço. Método: Revisão integrativa da literatura. Resultados: Amostra final composta por 13 estudos publicados entre 1998 a 2015. Pela análise temática dos estudos foram identificados quatro temas maiores: “repercussões físicas da radioterapia”, “repercussões psicológicas e emocionais da radioterapia”, “falta de informação sobre o tratamento e a postura do profissional de saúde perante os efeitos adversos do tratamento” e “redes de apoio”. Conclusão: Os estudos evidenciaram que o tratamento radioterápico trouxe repercussões negativas importantes na vida dos pacientes frente às reações e rearranjos na vida e nos papéis desempenhados dentro da família, decorrentes do tratamento. Verificou-se também uma lacuna importante de conhecimento sobre a temática, demostrando a necessidade de novos estudos, com abordagem qualitativa, para melhor compreensão desta experiência, refletindo em aprimoramento da assistência.

Over the last few decades, significant improvements have been made in the radiotherapy (RT) treatment of head and neck malignancies. The progressive introduction of intensity-modulated RT and the use of multimodality imaging for target volume and organs at risk delineation, together with the use of altered fractionation regimens and concomitant administration of chemotherapy or targeted agents, have accompanied efficacy improvements in RT. Altogether, such improvements have translated into improvement in locoregional control and overall survival probability, with a decrease in the long-term adverse effects of RT and an improvement in quality of life. Further progress in the treatment of head and neck malignancies may come from a better integration of molecular imaging to identify tumor subvolumes that may require additional radiation doses (ie, dose painting) and from treatment adaptation tracing changes in patient anatomy during treatment. Proton therapy generates even more exquisite dose distribution in some patients, thus potentially further improving patient outcomes. However, the clinical benefit of these approaches, although promising, for patients with head and neck cancer need to be demonstrated in prospective randomized studies. In this context, our article will review some of these advances, with special emphasis on target volume and organ-at-risk delineation, use of molecular imaging for tumor delineation, dose painting for dose escalation, dose adaptation throughout treatment, and potential benefit of proton therapy.
