Purpose: Head and neck cancers (HNCs) usually present a poor prognosis and cause high morbidity rates. Recent surveys have demonstrated that HNC incidence rates are still on the increase in many countries. Our study objective was to assess the end-of-life care for patients with HNCs in Taiwan.Methods: Data was retrieved from Taiwan's National Health Insurance Research Database, where we identified patients who had been diagnosed with HNCs from January 1997 to December 2010. Each patient's annual trend of opioid use and hospice care needs, along with the distribution of place of death in the study cohort, were all analyzed.Results: A total of 98,211 HNC patients diagnosed between 1997 and 2010 were eligible for this study. The majority of HNC patients died in hospital. Patients who were male, lived in capital area, had a higher income, had received palliative hospice care, and had been prescribed opioids tended to choose to die at home or in hospice wards. Both opioid prescription and hospice care have increased during the past 10 years; however, the rate of palliative hospice care remained below 50%.Conclusions: Our results demonstrate that greater efforts are needed to implement palliative care for HNC patients in Taiwan.

The aim of this study was to investigate the association between microsatellite alteration in the surgical margins and local recurrence of oral cavity squamous cell carcinoma patients. Surgical specimens confirmed by pathological examination and corresponding surgical margins were collected from 120 oral cavity squamous cell carcinoma patients. Ten microsatellite markers were examined in the tumor specimens and paired surgical margins, which proved to be negative on pathological assessment. The specimens and surgical margins were amplified by polymerase chain reaction followed by computerized analysis. Forty-two specimens (35.0 %) with microsatellite instability (MSI) in at least one marker were found, and more than half of the specimens ( n = 73, 60.8 %) had loss of heterozygosity (LOH) in at least one marker. Although MSI and LOH were not associated with the prognosis of oral cavity squamous cell carcinoma patients, presence of MSI in the tumor-free surgical margins increased the risk of local recurrence (hazard ratio: 9.549; 95 % confidence interval: 4.143-22.01). Genetic analysis of tumor-free surgical margins is a useful tool for identifying oral cavity squamous cell carcinoma patients who are vulnerable to local recurrence. [ABSTRACT FROM AUTHOR]

We investigated the impact of fibrin glue on postoperative drainage amount and duration in head and neck cancer patients who underwent neck dissection. This study was a prospective randomized controlled trial. Patients who were scheduled to undergo neck dissection due to head and neck cancer were eligible for this study. After receiving a detailed explanation, all patients signed an informed consent form before enrollment. Patients were then randomly assigned to the study group (fibrin glue) or control group. In the study group, 2 ml of fibrin glue (Tissucol; Duploject, Baxter AG) was applied on the surface of the surgical wound before closure. Basic demographic data along with tumor-related features, operation-related variables, postoperative drainage amount/duration, postoperative pain, and analgesic usage were collected and analyzed. A total of 15 patients were included in the final analyses, with eight patients in the study group and seven patients in the control group. No significant differences were found between the two groups in age, gender, primary site, clinical N stage, neck dissection levels, perioperative bleeding, postoperative drainage amount/duration, hospitalization duration, and postoperative pain status. The application of 2 ml fibrin glue by the method described herein did not reduce the postoperative drainage amount/duration nor the postoperative pain status in patients who underwent neck dissection.

The aim of this study was to investigate the factors associated with infection at the recipient site of pectoralis major myocutaneous flap (PMMF) of head and neck cancer patients. We retrospectively reviewed head and neck cancer patients who underwent PMMF reconstruction and identified those with recipient site infection. Variables of patients with and without infection were compared and associated factors were investigated by logistic regression model. A total of 478 patients were included in the final analysis and 183 patients (38.3 %) developed recipient site infection. Lower margin of skin island, concurrent tracheotomy, diabetes mellitus, mandibular plate reconstruction, prior radiation, and peri-operative blood transfusion were independent factors associated with recipient site infection of PMMF. Skin island of PMMF beyond the eighth intercostal space markedly increased the risk of recipient site infection after major head and neck cancer surgery. Recognition of relevant factors associated with infection may help surgeons to identify those at risk. [ABSTRACT FROM AUTHOR]

We investigated the post-operative surgical site infection (SSI) rate in oral cavity cancer patients who had previous operation in the oral cavity region and compared it with that of patients without previous operation. We retrospectively reviewed over 1,000 chart records of oral cavity cancer patients from January 2004 to November 2010 and relevant data were collected. Statistical methods included descriptive statistics, bivariate analyses, and a multiple logistic regression model for investigating the relevant factors of post-operative SSI. A total of 894 patients were enrolled in the final analyses. The overall post-operative SSI rate was 20.8%. Previous history of operation was identified in 173 patients (19.4%). There was no significant difference in post-operative SSI rate between the patients with previous operation and those without (22.5 vs. 20.4%, P = 0.601). Previous operation in the oral cavity region was not associated with increased post-operative SSI rate in oral cavity cancer patients. [ABSTRACT FROM AUTHOR]
