The article discusses research which investigated the clinical course and risk factors leading to the formation of a pharyngocutaneous fistula (PCF) following total laryngectomy (TL) in patients with laryngeal cancer. Topics discussed include description of the study design, the performance of salvage TL due to failure RT or CRT in 59 patients and TL as the primary treatment in 43 patients, postoperative complications manifested by the patients and clinical applicability of the study.

Objectives Elective neck dissection during salvage laryngectomy is controversial. The goal of our study was to evaluate the effect of elective neck dissection during salvage laryngectomy in patients with locally advanced disease at recurrence. Design Multicentre, retrospective study. Settings Two tertiary medical centres. Participants Eighty-seven patients treated by salvage laryngectomy. Main outcome measures Disease-Free and Overall Survival. Results Fifty-seven patients underwent salvage total laryngectomy for locally advanced recurrent squamous cell carcinoma of the larynx, and 30 patients underwent salvage laryngectomy for limited recurrent disease. Elective lateral neck dissection was performed in 48 patients. The groups were similar in age, sex, initial TNM stage and pre-operative treatment. Survival analysis showed that both disease-free survival and overall survival were improved in patients with locally advanced disease who underwent elective neck dissection. This beneficial effect was not demonstrated in patients with limited disease at recurrence. Multivariate analysis showed that the extent of the recurrent disease as well as elective neck dissection was associated with improved disease-free survival and overall survival. Conclusions Elective neck dissection during salvage total laryngectomy seems to improve survival in patients with advanced local disease at recurrence. The role of neck dissection in the treatment of smaller tumours awaits further studies. [ABSTRACT FROM AUTHOR]

Objective:To identify the prognostic significance of specific lymph node related characteristics for disease persistence and recurrence in patients with pre- or intra-operative evidence of neck metastases and no other risk factors.Method and resultsSixty-eight patients were identified; 50 per cent had persistent or recurrent disease. All underwent the same treatment strategy. There were no statistically significant differences in any of the patient- or tumour-related parameters when patients with and without persistence or recurrence were compared. Patients with recurrent or persistent disease had significantly larger (>3 cm) metastatic lymph nodes, but there were no differences regarding other lymph node related parameters (i.e. number, extracapsular extension, number of lymph nodes with extracapsular extension, and central vs lateral neck location). On multivariate analysis, however, none of the parameters were predictive of persistent or recurrent disease.Conclusion:In papillary thyroid carcinoma patients with no other risk factors, pre- or intra-operative evidence of cervical metastases was associated with a very high rate of disease persistence or recurrence. Specific lymph node characteristics were not shown to have prognostic significance. [ABSTRACT FROM PUBLISHER]

Background: The increase in life expectancy combined with the relatively high incidence of thyroid disease requiring surgery in the elderly has raised questions concerning the appropriate management of the older patient. Aim: Evaluation of the surgical management and outcome of thyroid disease requiring surgery in elderly patients. Methods: We performed a retrospective cohort study, in which the medical charts of 2,239 patients who underwent total thyroidectomy or hemithyroidectomy between 1995 and 2011 in a tertiary medical center were reviewed for clinical, disease-related, operative and outcome measures. Findings were analyzed between the patients aged more than 75 years for whom complete information was available (n = 255) and a control group of 100 patients aged 40-60 years matched for sex and extent of surgery. Results: The prevalence of comorbidities was significantly higher in the elderly. Presenting symptoms were similar in the two groups; in approximately 25% of both groups thyroid cancer was an incidental finding. There were no between-group differences in surgery duration, time to anesthesia induction, recovery time from anesthesia, or rate of postoperative complications. Hospitalization was 3 days longer on average in the older group. Malignancy rates and distribution of histologic subtypes were similar in the two groups, although the older group presented with significantly higher rates of advanced disease stage and larger tumors. There were no differences in recurrence rate both locoregional and distant metastases. However, a higher proportion of older patients failed to achieve cure. Conclusion: Although older patients with thyroid disease have more comorbidities and advanced disease, there is no practical difference in their operative management and surgical outcome compared to younger patients. Surgery should not be deferred solely on the basis of age in the presence of compelling indications; rather, the decision should be based on individual risk-benefit analysis. Copyright © 2013 S.

Clin. Otolaryngol. 2010, , 402-408 To investigate the prognostic significance of positive margin and disease course in partial laryngectomy for advanced laryngeal carcinoma and radiation failure. Retrospective case control study. A major tertiary referral centre. Patients who underwent partial laryngectomy for advanced laryngeal carcinoma or for radiation failure with at least 2 years of follow-up Margin status versus primary treatment and salvage treatment versus disease-free survival and overall survival. Twenty nine patients with sufficient follow-up data were found. Twelve patients had histological positive margin. Five of the 12 patients with a histological positive margin failed surgery as did four patients with clear margins. A positive margin had no effect on disease-free survival ( P = 0.287) but was associated with poorer overall survival ( P = 0.051). Of 11 patients treated primarily with surgery, recurrence was documented in one of eight with a positive margin and none of three with clear margins. Of 18 patients who underwent surgery secondary to radiation failure, recurrence was documented in all four with a positive margin and 4 of 14 with negative margins. Extended frontolateral resection, performed only in radiation failures, was associated with worse disease-free survival. Non-irradiated patients with involvement of a single margin after partial laryngectomy may be spared total laryngectomy if adjuvant radiation is administered. Patients who fail radiation should undergo radical partial laryngectomy, with conversion to total laryngectomy in those with a positive margin. [ABSTRACT FROM AUTHOR]

We sought to define risk factors for facial nerve involvement in parotid gland carcinoma and assess the outcome of facial nerve reanimation. Medical records were reviewed of 66 patients who underwent surgery for parotid carcinoma in 2000–2007 at a tertiary hospital. Patient and tumor characteristics were compared between patients with and without facial nerve involvement and were analyzed on their influence on functional outcome following reanimation. Facial nerve involvement was verified intraoperatively in 24 patients, of whom 16 underwent reanimation during ablative surgery. Deep lobe invasion was significantly associated with intraoperative finding of facial nerve involvement. Tumors larger than 4 cm and salivary duct carcinoma had an obvious trend for facial nerve involvement. House-Brackmann score at 12 months was 3–4 in most patients. Deep lobe involvement and large tumor size may identify patients at risk of facial nerve involvement. Reanimation is associated with good functional outcome regardless of patient’s age.

Background: Verrucous carcinoma occurs infrequently in the vocal folds. This tumour has an excellent prognosis with proper treatment. Management strategies include surgery, radiotherapy or both. Aim: To evaluate the long-term results of type I and II laser cordectomy for the treatment of verrucous carcinoma of the vocal folds. Materials and methods:We reviewed the files of 18 patients with verrucous carcinoma of the vocal folds treated by type I or II laser cordectomy in our department from 1989 to 2006, and recorded clinical and outcome data. Results: None of the patients had any major post-operative complications. All had a subjectively satisfactory quality of voice, with no morbidity. Patient follow up ranged from three to 228 months (mean, 48 months). Five patients were treated with post-operative radiotherapy for persistent disease, of whom four underwent repeated surgery due to recurrence. Conclusion: Type I or II laser cordectomy is a safe, feasible, secure method of treating verrucous carcinoma of the vocal folds. There were no major complications in our patient series. Most recurrent disease was manageable locally with repeated surgery. [ABSTRACT FROM AUTHOR]

Background: Oral cancer is a common and lethal malignancy. Direct contact between saliva and the oral cancer lesion makes measurement of tumour markers in saliva an attractive alternative to serum testing.Methods: We tested 19 tongue cancer patients, measuring the levels of 8 salivary markers related to oxidative stress, DNA repair, carcinogenesis, metastasis and cellular proliferation and death.Results: Five markers increased in cancer patients by 39-246%: carbonyls, lactate dehydrogenase, metalloproteinase-9 (MMP-9), Ki67 and Cyclin D1 (CycD1) (P< or =0.01). Three markers decreased by 16-29%: 8-oxoguanine DNA glycosylase, phosphorylated-Src and mammary serine protease inhibitor (Maspin) (P< or =0.01). Increase in salivary carbonyls was profound (by 246%, P=0.012); alterations in CycD1 (87% increase, P=0.000006) and Maspin (29% decrease, P=0.007) were especially significant. Sensitivity values of these eight analysed markers ranged from 58% to 100%; specificity values ranged from 42% to 100%. Both values were especially high for the CycD1 and Maspin markers, 100% for each value of each marker. These were also high for carbonyls, 90% and 80%, respectively, and for MMP-9, 100% and 79%, respectively.Conclusion: The significance of each salivary alteration is discussed. As all alterations correlated with each other, they may belong to a single carcinogenetic network. Cancer-related changes in salivary tumour markers may be used as a diagnostic tool for diagnosis, prognosis and post-operative monitoring. [ABSTRACT FROM AUTHOR]

Study Objectives: High dose rate (HDR) endobronchial brachytherapy is widely used as a palliative treatment for symptomatic airway obstruction by primary or secondary malignant tumors. We report on a successful use of HDR brachytherapy in patients with nonmalignant airway obstruction.Design: Case seriesPatients: Six patients received HDR brachytherapy for airway obstruction caused by granulation tissue around a metal stent placed for restoration of the airway patency for nonmalignant causes. In four patients, brachytherapy was performed following recurrent occlusion of the airway by granulation tissue formation; in two patients, it was done as a prophylactic procedure.Intervention: HDR brachytherapy catheters were passed through the metal stents under direct fluoroscopic guidance. Simulation and computerized treatment planning were done, and a single dose of 10 Gy was administered using a brachytherapy remote afterloader with a (192)Ir source. The dose was prescribed to a distance of 1 cm from the center of the source, with a margin of 1 cm from the proximal and distal ends of the stent.Results: At a median follow-up of 15 months, moderate granulation tissue formation was observed in only one patient; in four others, it was categorized as minimal, 5 to 30 months from the procedure. Restoration of the lumen was complete in four patients, near complete in one patient, and partial in one patient. In one patient, previously treated by external radiotherapy, local tissue necrosis was evident.Conclusion: HDR brachytherapy can be used safely for nonmalignant airway obstruction. Further studies including more patients and longer follow-up are needed. [ABSTRACT FROM AUTHOR]

This article discusses various issues related to chronic middle ear effusion as a possible cause of protracted vomiting and of failure to thrive in infancy. The article presents a case report in this regard. Protracted vomiting in infancy presents a major diagnostic problem that entails consideration of infectious causes, anatomic lesions, endocrinopathies and neurometabolic disorders. Chronic otitis media with effusion, regarded as one of the most common chronic disorders in childhood, is not included among the numerous conditions associated with vomiting. The article authors describe three infants who suffered from persistent vomiting with failure to thrive and who had undergone lengthy and extensive in-hospital evaluation prior to recognition of chronic middle ear effusion as the cause of their symptoms. Vomiting is a common manifestation of acute otitis media, during which an inflammatory response of serous labyrinthitis is believed to occur. As effusion in the middle ear can cause tinnitus, sensorineural hearing loss and even vertigo, symptoms attributable to inner ear stimulation, it would not be surprising that vomiting would also occur as part of the clinical presentation of chronic otitis media with effusion.
