Time interval between (chemo)radiotherapy and subsequent laryngectomy is not prognostic for post operative complications and survival.

PURPOSE: Pharyngocutaneous fistula (PCF) formation and swallowing difficulties are common and troublesome complications following total laryngectomy (TL). Prior (chemo)radiotherapy ((C)RT) is thought to be a risk factor for these complications, but there is conflicting evidence as to whether the time interval between (C)RT and TL is important. The impact of time interval on these complications and also its impact on overall survival are investigated. METHODS: This is a retrospective case note review of all patients undergoing TL at the University Medical Center, Utrecht, The Netherlands over the 10-year period from January 2008 to December 2017. The cohort was split into those who underwent TL within a year of finishing (C)RT and those longer than 1 year. RESULTS: One hundred and twenty-six patients (108 males, 18 females), with a mean age of 66 underwent total laryngectomy after prior (C)RT in the study period. Overall 5-year survival was 35% with a median follow-up of 30 months. Fifty-four patients underwent laryngectomy within a year of their (C)RT versus 72 patients who had a time interval of more than one year. No differences in PCF rate, risk of dilatation or overall survival could be found between the two groups. CONCLUSIONS: In this modern cohort, time interval between (C)RT and surgery did not impact PCF rate, risk of dilatation or overall survival.

Factors predictive of outcome following primary total laryngectomy for advanced squamous cell carcinoma.

The increasing use of primary chemoradiation (CRT) for laryngeal squamous cell carcinoma (SCC) means that historical surgical data sets are not representative of the modern laryngectomy patient. We analyse a contemporary total laryngectomy (TL) cohort to identify factors predictive of outcome. This is a retrospective consecutive case note review in a UK tertiary referral centre. Demographic, staging, treatment and outcome data were collected. Oncological outcomes are expressed using the Kaplan-Meier method. The log-rank test was used for univariate analysis and cox regression for multivariate analysis. Sixty consecutive patients between 2003 and 2010 underwent primary TL, 28 including partial pharyngectomy. Median age was 61 years and mean follow-up was 24 months (1-78 months). Thirty six patients died during the study period, 24 of their disease. Of the disease-specific deaths, two occurred peri-operatively, four from local, two from regional and 18 from distant disease [two patients had simultaneous local and distant recurrence (DR)]. Five-year overall survival, disease-specific survival, loco-regional recurrence-free survival and distant recurrence-free survival (DRFS) were 36, 51, 87, 62 %, respectively. Of 17 parameters analysed, pN-stage, extra-capsular spread, a non-cohesive tumour front, thyroid infiltration and involvement of level 6 were significant predictors of disease-specific survival (DSS) on univariate analysis. pN > 1 and the presence of adverse histological features were found to be independent predictors of DSS and DRFS on multivariate analysis. Neither was significantly associated with loco-regional recurrence-free survival. Around half of patients who undergo TL for stage IV SCC will die of disease within 5 years, with most deaths attributable to DR. Surgery provides excellent loco-regional control but patients, especially those with advanced nodal disease and/or adverse histological features, should be thoroughly screened for occult distant disease. Level of evidence 4.

Pre-operative tracheostomy does not impact on stomal recurrence and overall survival in patients undergoing primary laryngectomy.

Pre-operative tracheostomy (POT) to secure a critical airway up to several weeks before definitive laryngectomy in patients with laryngeal cancer has been proposed as a risk factor for poor oncologic outcome. Few modern papers, however, examine this question. The aim of this study is therefore to determine whether POT affects oncologic outcome with an emphasis on stomal/peristomal recurrence. This is a retrospective case note review of 60 consecutive patients undergoing curative primary total laryngectomy (TL) for advanced laryngeal squamous cell carcinoma (SCC). Demographic, staging, treatment and outcome data were collected. 27/60 (45 %) patients had POT and 33/60 did not. No patient underwent laser debulking. Median age was 62 years (39-90 years) and median follow-up of survivors was 31 months. 5-year overall survival (OS), disease-specific survival (DSS) and local recurrence-free survival (LRFS) of patients undergoing POT versus no POT was 28 versus 39 % (p = 0.947), 55 versus 46 % (p = 0.201) and 96 versus 88 % (p = 0.324) respectively. No statistically significant difference in OS, DSS and LRFS was found between patients undergoing POT and those not. Despite the relatively small case series, this evidence should reassure surgeons without the ability to perform trans-oral debulking that they should not hesitate to perform tracheostomy on a patient with airway obstruction due to laryngeal cancer. Appropriate definitive treatment meant that POT was not a risk factor for poor oncological outcome in our series.

Arterial calcification on preoperative computed tomography imaging as a risk factor for pharyngocutaneous fistula formation after total laryngectomy.

BACKGROUND: Research in esophageal surgery showed that computed tomography (CT) assessed arterial calcification (AC) is associated with postoperative complications. We investigated the association between AC and pharyngocutaneous fistula (PCF) formation after laryngectomy. METHODS: This was a retrospective cohort study of patients undergoing laryngectomy. AC was scored at 10 different anatomical locations on CT imaging, blinded for PCF occurrence. Association with PCF was investigated using logistic regression. RESULTS: The 224 patients were included; 62 (27.7%) developed a PCF. Moderate to severe AC was widespread in patients undergoing TL; 7.1% of patients had at most mild AC, of whom 1 experienced a PCF (p = 0.05). A higher cumulative calcification score was associated with PCF in univariable (OR 1.11, p = 0.04) and multivariable analysis (OR 1.14, p = 0.05). CONCLUSION: AC is widespread in patients undergoing laryngectomy and its burden is associated with PCF. Extensive AC on preoperative imaging may be considered a risk factor for PCF.

Preoperative low skeletal muscle mass as a risk factor for pharyngocutaneous fistula and decreased overall survival in patients undergoing total laryngectomy.

BACKGROUND: Low skeletal muscle mass (SMM) is associated with postoperative complications, prolonged hospital stay, and short overall survival (OS) in surgical oncology. We aimed to investigate this association in patients undergoing total laryngectomy (TL). METHODS: A retrospective study was performed of patients undergoing TL. SMM was measured using CT or MRI scans at the level of the third cervical vertebra (C3). RESULTS: In all, 235 patients were included. Low SMM was observed in 109 patients (46.4%). Patients with low SMM had more pharyngocutaneous fistulas (PCFs) than patients with normal SMM (34.9% vs 20.6%; P = .02) and prolonged hospital stay (median, 17 vs 14 days; P < .001). In multivariate analysis, low SMM (hazards ratio, 1.849; 95% confidence interval, 1.202-2.843) and high N stage were significant prognosticators of decreased OS. CONCLUSION: Low SMM is associated with PCF and prolonged hospital stay in patients undergoing TL. Low SMM is an independent prognostic factor for shorter OS.

Dilation after laryngectomy: Incidence, risk factors and complications.

BACKGROUND: Neopharyngeal stenosis is a recognized sequela of total laryngectomy (TL). We aim to investigate the incidence of stenosis requiring dilation, risk factors for stenosis and complications of dilation. METHODS: Retrospective cohort study of patients undergoing TL in two dedicated head and neck centers in the Netherlands. RESULTS: A total of 477 patients, (81% men, median age of 64 at TL) were included. Indication for TL was previously untreated primary tumor in 41%, salvage following (chemo)radiotherapy (CRT) in 44%, dysfunctional larynx in 9% and a second primary tumor in 6%. The cumulative incidence of dilatation at 5 years was 22.8%, and in total 968 dilatations were performed. Median number of dilations per patient was 3 (range 1-113). Female gender, a hypopharynx tumor, and (C)RT before or after the TL were significantly associated with stenosis requiring dilation. We observed 8 major complications (0.8%) predominantly during the first dilation procedures. Use of general anesthesia is a risk factor for complications. The most frequent major complication was severe esophageal perforation (n = 6 in 5 patients). CONCLUSION: The cumulative incidence of pharyngeal stenosis needing dilation was 22.8% at 5 years. Roughly half of these patients could be treated with a limited number of dilations, the rest however needed ongoing dilations. Major complications are rare (0.8%) but can be life threatening. General anesthetics is a risk factor for complications, and complications occurred predominantly during the first few dilations procedures. This should alert the physician to be extra careful in new patients.

Impact of human papillomavirus on outcome in patients with oropharyngeal cancer treated with primary surgery.

BACKGROUND: Knowledge about prognostic factors in surgically treated patients with oropharyngeal squamous cell carcinoma (SCC) is limited. The purpose of this study was to identify influential factors on survival in a large cohort of patients with surgically treated oropharyngeal SCC. METHODS: Retrospective analysis of survival estimates in patients with surgically treated oropharyngeal SCC using tumoral positivity for human papillomavirus (HPV) and risk-of-death categories according to a study from 2010 as stratification factors. RESULTS: The 5-year overall survival (OS) and disease-specific survival (DSS) rates after surgery alone were higher in HPV-associated oropharyngeal SCC (OS 80% vs 62%; P = .01; DSS 92% vs 76%; P = .03). Patients in the low-risk category had higher survival rates (OS 91%; DSS 99%) than patients in the intermediate-risk group (OS 63%; DSS 83%), and high-risk group (OS 61%; DSS 75%). CONCLUSION: Nonsmokers with HPV-positive oropharyngeal SCC have a better prognosis than smokers with HPV-positive oropharyngeal SCC and also than patients with HPV-negative tumors when treated by surgery alone.

Does airway intervention before primary nonsurgical therapy for T3/T4 laryngeal squamous cell carcinoma impact on oncological or functional outcomes?

QUESTIONS UNDER STUDY: Even today, some patients with laryngeal cancer present with airway obstruction necessitating an intervention in the form of either a tracheostomy or transoral laser debulking (TOL). Controversy exists as to whether such an intervention is a risk factor for poor oncological or functional outcome in patients who then undergo primary (chemo)radiotherapy. METHODS: Retrospective chart review of all patients undergoing primary curative nonsurgical treatment for T3/T4 laryngeal squamous cell cancer at the University Hospital Zurich between 1981 and 2011. RESULTS: A total of 29/114 patients had an airway intervention before initiation of (chemo)radiotherapy (21/29 tracheostomies, 8/29 TOL). Kaplan-Meier analysis showed no statistical difference in oncological outcomes between the groups with and without intervention (5 year overall survival: 52% vs 70%, disease specific survival: 73% vs 79%, recurrence free survival: 53% vs 63%). In functional terms, we report an overall functional larynx rate of 60%. CONCLUSIONS: Airway intervention was not found to be a risk factor for poor oncological or functional outcome in this patient group.

Success of salvage treatment: a critical appraisal of salvage rates for different subsites of HNSCC.

OBJECTIVE: Despite advances in interdisciplinary treatment protocols, the chance of cure for recurrent head and neck squamous cell carcinoma (HNSCC) following failed primary therapy is poor and often entails a high morbidity. Recurrence rates vary widely in the literature depending on tumor localization, primary tumor stage, and treatment modality, and only a minority of patients can be salvaged. STUDY DESIGN: Historical cohort study. SETTING: This study valuates the outcomes of patients treated for recurrent squamous cell carcinoma of the larynx, pharynx, and oral cavity in the largest tertiary referral center of Switzerland to find predictors for survival in salvage surgery with curative intent. SUBJECTS AND METHODS: Included were 176 consecutive patients with recurrent disease after primary curative treatment of HNSCC, in locations mentioned previously. Kaplan-Meier survival analyses with log-rank testing were performed depending on T and N stage, gender, treatment, and location of first relapse to evaluate the impact on overall survival, disease specific survival, and recurrence free survival. RESULTS: Overall successful salvage rates were 49.2% for laryngeal recurrence, 35.1% for oral cavity, 32.7% for oropharyngeal, and a mere 17.4% for hypopharyngeal recurrences. Predictive factors for better outcome were location of recurrence, female gender, lymph node status, and extent of salvage treatment. CONCLUSION: In case of recurrent disease, laryngeal cancers showed the best salvage rates, whereas in hypopharyngeal relapses, very few patients could be successfully salvaged. Patients therefore should be carefully selected and counseled for salvage treatment according to patient motivation, age, type of previous treatment, surgical resectability, and exclusion of distant recurrence.

Epithelial cyst in the posterior triangle of the neck: atypical branchial cyst or cystic lymph node metastasis?

We report the case of a 66-year-old man with a cervical neck mass located behind the left sternocleidomastoid muscle. To exclude malignancy, a full workup, including clinical, radiological, and cytological examination, was performed but failed to provide a definitive diagnosis. Histological analysis following excisional biopsy revealed a benign epithelial cyst, consistent with an atypically located branchial cyst. We describe an approach to the management of these neck masses and discuss several theories of the etiology of branchial cysts and how they may come to be abnormally located.

Fatally invasive actinomycosis masquerading as a tonsillar carcinoma.

BACKGROUND: Actinomyces is a bacterial rod found in the normal oral flora. It can gain entry to the submucosa via trivial wounds and ultimately lead to slow growing lesions which may mimic cancerous lesions. METHODS AND RESULTS: We present the case of an elderly, immunosuppressed woman who presented with a herald bleed from a tonsillar lesion. Despite initial operative arrest of the hemorrhage, she died of a carotid blowout. At autopsy, no sign of cancer was found, but rather an invasive actinomycosis. CONCLUSION: Although actinomycosis of the tonsil is well known and has even been described as mimicking tonsillar cancer, this is, to our knowledge, the first report of a carotid blowout secondary to actinomycosis.

Airway management in head and neck cancer patients undergoing microvascular free tissue transfer: delayed extubation as an alternative to routine tracheotomy.

QUESTIONS UNDER STUDY: The aim of this study was to evaluate two practices of airway management in patients undergoing head and neck cancer (HNC) resection and microvascular free tissue transfer (MFTT), and to assess the advantages and disadvantages of the two approaches. METHODS: Patients undergoing a delayed extubation approach (NO-TRACH group) and patients undergoing primary tracheotomy (PRIM-TRACH group) were retrospectively evaluated in terms of perioperative and postoperative outcome measures. RESULTS: Not performing routine tracheotomy was safe and no perioperative airway complications occurred. NO-TRACH patients were extubated after 1.1 ± 0.9 days (mean ± standard deviation) and secondary tracheotomy was necessary in three patients (13%). NO-TRACH patients revealed decreased duration of surgery (p <0.05) and showed trends to earlier resumption of oral feeding and decreased length of hospitalisation. Flap complication rates were similar in both groups, with an overall flap survival rate of 97.5% (n = 39/40). CONCLUSIONS: With appropriate postoperative care, carefully selected patients undergoing major HNC resections with MFTT can be safely managed without routine tracheotomy.
