Reirradiation in head-and-neck cancers in resource-constraint centers

Reirradiation in head and neck cancers.

Salvage surgery is the mainstay of treatment for recurrences or secondary primary tumors in areas that were irradiated earlier. However, locoregional recurrence remains the main cause of death after surgery. Adjuvant reirradiation dramatically reduces locoregional recurrences but the risk-benefit ratio seems to be advantageous mostly for residual microscopic disease. In contrast, the rate of di...

Pesticide Exposure and Head and Neck Cancers: A Case-Control Study in an Agricultural Region

Introduction: Causes of head and neck cancers (HNCs) are multifactorial, and few studies have investigated the association between chemical exposure and HNCs. The objective of this study was to investigate associations between HNCs, agricultural occupations, and pesticide exposure. The potential for the accumulation of pesticides in the adipose tissue of patients was also investigated.   Materi...

Effect of cryotherapy on oral mucositis in patients with head and neck cancers receiving radiotherapy

Background: Mucositis is an important adverse effect of cancer treatment. The aim of this study was to investigate the effect of ice cubes on oral mucositis following head and neck radiotherapy. Materials and Methods: A randomized controlled trial was conducted on 40 head and neck cancer patients who underwent radiotherapy. The patients were randomly divided into two experimental and control gr...

A Review on the Efficacy of Chemotherapy in Locally Advanced Head and Neck Cancers

Background and Aims: Chemotherapy is utilized as a part of combined-modality programs to achieve organ preservation and improve survival in patients with locally advanced head and neck cancer. Combinedmodality protocols can be used in three forms: a) neoadjuvant induction chemotherapy before definitive surgery or radiotherapy; b) concomitant chemoradiotherapy; and c) sequential therapy consisti...
