Retropharyngeal and parapharyngeal abscess in children—Epidemiology, clinical features and treatment

Objective

To describe the clinical presentation, diagnosis, management and complications of children with retropharyngeal abscesses (RPAs) and parapharyngeal abscesses (PPAs).

Methods

A retrospective chart review was conducted at two tertiary care, pediatric hospitals in Israel. The medical records of all children <18 years who had been admitted with a diagnosis of RPA or PPA during an 11-year period (January 1997 to February 2008) were reviewed. Data on demographics, presenting symptoms, physical examination findings, imaging studies and interpretation, laboratory results, hospital course, medical treatment and surgical interventions were retrieved.

Results

A total of 39 children were diagnosed as having RPA (n = 26, 67%) or PPA (n = 13, 33%). There was a predominance of boys (61.5%). The mean age of all the children at diagnosis was 4 years. The annual incidence increased over the 11-year period. The most common symptoms at presentation included fever (n = 27, 70%) and neck pain (n = 24, 62%). The physical examination revealed cervical lymphadenopathy in 30 children (77%), limitation of neck movements in 25 (64%), torticollis in 21 (54%), drooling in three (8%), and stridor in two (5%). Computerized tomographic (CT) scanning with contrast was performed in 37 patients (95%), of whom 17 underwent surgical drainage. Thirteen children were positively diagnosed as having an abscess by the finding of pus at surgery, of whom 12 had been found to have an abscess on their CT scan. All the patients received intravenous antibiotics. There was no significant difference in the duration of hospital stay between those who underwent surgery and those who were treated with antibiotics alone. There were no treatment failures and no complications in either of the two groups.

Conclusion

Children with RPA most commonly present with restricted neck movements, fever and cervical lymphadenopathy, and rarely with respiratory distress or stridor. Many patients with RPA and PPA can be treated successfully without surgery. CT scans are helpful in diagnosing and assessing the extent of the infection, but they are not always accurate.     

Pediatric deep space neck infections in U.S. children, 2000–2009

Objective

Deep space neck infections (DNI) are common pediatric illnesses, which can lead to significant morbidity and healthcare expenditures. Recent studies suggest that the incidence of pediatric DNI in the United States is increasing, but no nationally representative studies exist. This study sought to characterize pediatric DNI at the national level over the past decade and to determine whether U.S. incidence of pediatric DNI and associated resource utilization changed from 2000 to 2009.

Methods

The Kids’ Inpatient Database (KID) was used to evaluate pediatric DNI incidence, demographics, and outcomes from 2000 to 2009. Cases were identified using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes for peritonsillar abscess (475), parapharyngeal abscess (478.22), and retropharyngeal abscess (478.24). Regression analyses within each year and across the entire study period were performed on variables of interest including performance of imaging studies, operative intervention, length of hospital stay and total hospital charges.

Results

The incidence of retropharyngeal abscess increased significantly from 0.10 cases per 10,000 in 2000 to 0.22 in 2009 (p = 0.02). There was no significant change during this time period in the incidence of combined DNI (1.07–1.37 cases per 10,000, p = 0.07), peritonsillar abscess (0.82–0.94 cases per 10,000, p = 0.12) or parapharyngeal abscess (0.08–0.14 cases per 10,000, p = 0.13). The percentage of retropharyngeal abscess patients managed surgically decreased (48–38%, p = 0.04) and the average length of hospital stay also decreased during this time (4.6–3.9 days, p = 0.03). There was a marked increase in the total inflation-corrected hospital charges per case for all DNI ($9,486–16,348, p = 0.005).

Conclusions

The incidence of pediatric retropharyngeal abscess has increased significantly from 2000 to 2009, without concurrent increases in the incidence of combined DNI, peritonsillar, or parapharyngeal abscesses. There has been a change in management of retropharyngeal abscesses during this time with a decrease in operative intervention and a decrease in the length of hospital stay. Hospital charges associated with all pediatric DNI have nearly doubled during this timeframe, warranting future epidemiologic resource utilization studies in this population.     

Surgical complications and recurrence after central neck dissection in cN0 papillary thyroid carcinoma

Objectives

To evaluate surgical complications and recurrence patterns after central neck dissection (CND) in papillary thyroid carcinoma (PTC).

Methods

A retrospective analysis was performed on 361 patients who underwent total thyroidectomy with or without CND for PTC from 2000 to 2007. Clinicopathological results and recurrence were stratified according to treatment modality.

Results

Incidence of occult central metastasis of PTC was 64.3%. With respect to surgical morbidities, the total thyroidectomy (TT) with CND group exhibited a significantly higher incidence of transient vocal fold paralysis (10.0% vs 3.4%, p = 0.029) and permanent hypocalcaemia (11.4% vs 4.5%, p = 0.041), and significantly prolonged mean operating time (195.8 min vs 153.0 min, p < 0.001) than the TT alone group. Analysis of the recurrence patterns revealed that level IV was most commonly involved in both groups. When the location of recurrence was categorised into central and lateral neck, the recurrence rate in the lateral neck was significantly higher than that in the central neck, regardless of initial CND.

Conclusions

CND was associated with permanent hypocalcaemia and transient vocal fold paralysis. The lateral neck was mainly involved in recurrence regardless of initial CND, suggesting the clinical benefit of CND may be small.     

Potential role of biofilms in deep cervical abscess

Objectives

Deep neck abscesses are complex head & neck problems that can lead to significant complications including life threatening infections. It is understood that the pathology of these infections is primarily polymicrobial. Although broad spectrum antibiotics can be effective for small abscesses, larger abscesses can be recalcitrant and difficult to treat with antibiotics. It has been demonstrated for several infectious diseases, including some of head & neck, that biofilm phenotypes present a unique model for recurrence and chronicity of infectious diseases. It is suspected that biofilm phenotypes could play a crucial role in the recalcitrance of large deep neck abscesses. This study presents initial evidence indicating the presence of polymicrobial biofilms in deep neck space infections.

Methods

Fourteen samples obtained via biopsy of abscess walls from deep neck spaces of patients undergoing surgical drainage. Eight patients were male and 6 were female. All but one patient were pediatric with ages ranging from 18 months to 32 years. All samples were processed and analyzed with scanning electron microscopy.

Results

Electron micrographs of 12 out of 14 specimens showed discrete biofilm architecture with individual bacteria, both rods and cocci, embedded within the matrix. This was starkly different from tissue surfaces devoid of biofilms.

Conclusions

This initial evidence suggests that biofilm phenotypes could play a role in the pathogenesis and recalcitrance of deep neck infections, particularly in larger abscesses.     

Recurrence pattern after conservative surgery for papillary thyroid carcinoma

Objective

Risk-based treatment represents the optimal management strategy for papillary thyroid carcinoma; however, the optimal extent of thyroidectomy and neck dissection remains controversial. This study aims to clarify the pattern of recurrence after conservative surgery in patients with papillary thyroid carcinoma.

Methods

We retrospectively reviewed 93 patients with papillary thyroid carcinoma treated with conservative surgery. We analyzed recurrence rate, recurrence pattern, risk factors for recurrence, salvage treatment, and disease-free survival (DFS) in patients stratified according to risk.

Results

The recurrence rate was significantly lower in the low-risk group compared with the high-risk group (14% vs 34%; p < 0.01). The recurrence pattern also differed between the two groups, with ipsilateral lateral neck recurrence being more common in the low-risk group (9%), while contralateral lateral neck recurrence was more common in the high-risk group (18%). Patients with contralateral thyroid lobe metastasis and/or direct contralateral thyroid lobe invasion showed a significantly higher rate of contralateral lateral neck metastasis than patients negative for both these features. The overall 5-year DFS was 81% in all patients. Advanced T and N classification, large primary tumor (≥4 cm), extrathyroidal invasion, and high-risk group were significantly associated with poorer 5-year DFS in univariate analysis.

Conclusion

Conservative surgery may represent a good treatment option for patients with low-risk papillary thyroid carcinoma. Tumor recurrence patterns differ between risk groups, with contralateral thyroid lobe lesions and direct contralateral lobe invasion being risk factors for contralateral lateral neck recurrence.     

Transoral negative-pressure catheter drainage of a retropharyngeal and mediastinal abscess

Purpose

A retropharyngeal abscess (RPA) is an extremely rare entity in adults that has a tendency to spread vertically and cause a mediastinal abscess. Traditionally, immediate aggressive drainage is recommended via a transcervical or transthoracic approach for the treatment of a retropharyngeal abscess with mediastinal extension. Here, we present a case of a retropharyngeal and mediastinal abscess using a transoral negative-pressure catheter drainage approach.

Patients and methods

A 24-year-old woman was admitted with a 4-day history of severe sore throat and painful swallowing. Computed tomography identified a retropharyngeal abscess extending to the upper posterior mediastinum. We performed transoral negative-pressure catheter drainage.

Results

The postoperative course was uneventful. The patient reported a rapid improvement in symptoms and had a good tolerance of the catheters in the nasal cavity. At 2 years postoperatively, physical examinations revealed no recurrence or surgical complications.

Conclusions

Transoral negative-pressure catheter drainage is a minimally invasive operation for the treatment of RPA in adults with or without a mediastinal abscess. This method could be recommended as an alternative approach in such cases.     

Management of neck metastases in T2N0 lip squamous cell carcinoma

Background

Prophylactic neck dissection (PND) is indicated when the chance of occult lymph node metastases from head and neck tumors is significant. There is no consensus regarding which tumor size PND would be indicated in cases of lip cancer.

Methods

A total of 139 patients with surgically treated lip cancer were selected. The size of the lesion (T) and the presence of lymph node metastases (N) were assessed by examining the medical records. For analysis purposes, the T2 group was divided into T2a (2 to 3 cm) and T2b (3 to 4 cm).

Results

The following distribution of incidence of neck metastases was observed in the study groups: 11.7% in T1, 9% in T2a, 43.7% in T2b, and 52.2% in T3 + T4. Statistical comparison of the groups (p) revealed the following results: T2a X T2b = 0.03; T2a X T3 + T4 = 0.001.

Conclusion

PND is indicated for tumors larger than 3 cm.     

Indicators of a more complicated clinical course for pediatric patients with retropharyngeal abscess

Objective

Determine clinical signs or symptoms associated with a more complicated clinical course in patients with retropharyngeal abscesses (RPAs).

Design

Retrospective chart review at a tertiary care level Children's hospital.Main Outcome Measures Age, presenting signs and symptoms, laboratory tests, imaging results, antibiotic therapy, surgical approach, pathogens isolated, and duration of hospitalization were evaluated to determine any factors associated with a more complicated clinical course (CCC).

Results

Fifteen of one hundred thirty pediatric patients with RPA were identified with a complicated clinical course (CCC). Eight of the fifteen required more than one procedure before the abscess resolved. Patients with multiple abscess sites had a statistically significantly greater chance of requiring multiple procedures to clear the infections (p < 0.001). Another seven presented with airway obstruction requiring an admission into the Pediatric Intensive Care (PICU) and/or intubation. All the patients requiring admission to the PICU presented with signs or symptoms of airway obstruction compared to ten of the one hundred fifteen patients (8.7%) with a smooth clinical course (SCC) (p < 0.001). Five patients from the CCC group required a bronchoscopy to secure the airway; seven patients required intubation following incision and drainage of the abscess for an average of 5 ± 3 days. There was no statistically significant difference between the two groups with respect to pathogens isolated, or antibiotics used.

Conclusion

Our study suggests that patients with a CCC are more likely to present with airway obstruction or multiple abscess sites than patients with SCC.     

Pediatric otolaryngology in a field hospital in the Philippines

Background

Major natural disasters adversely affect local medical services and resources. We sought to characterize pediatric patients presenting with otolaryngology-head and neck surgery (OTO-HNS)-related diseases/injuries to a field hospital over 11 days of operation, which was deployed to assist the healthcare facilities in Bogo, the Philippines, in the aftermath of typhoon Haiyan (Yolanda).

Methods

We reviewed charts of pediatric patients aged 0–18 years visiting our field hospital, who presented with OTO-HNS-related diseases/injuries. We also describe the structure of the field hospital, equipment, facilities and capabilities of our service, discuss medical and ethical concerns, and propose several recommendations for future similar missions.

Results

Of the 863 pediatric visits, 91 (11%) presented with OTO-HNS-related diseases/injuries, 3 of them were of recurring patients. Of the 88 included individual patients, 47 (53%) were boys, with an average age of 6.9 ± 4.9 years. Ear-related diseases, mostly acute otitis media (AOM), and neck-related diseases were the most common pathologies (49% and 16% of the patients, respectively). Antibiotic therapy was administered to 36 (41%) patients, mostly to children with AOM. Despite limited resources, we were able to perform surgical interventions on 8 (9%) patients, which included laceration suturing, abscess drainage and neck surgery.

Conclusions

Otolaryngologists have an important role in the treatment of children affected in a disaster area, at a time of an increased demand for healthcare. Unlike ‘acute phase’ missions, where traumatic injuries are the focus for treatment, ‘subacute’ phase missions provide more routine medical and surgical care.     

Prevalence and associated factors of pulmonary hypertension in Kenyan children with adenoid or adenotonsillar hypertrophy

Objectives

Adenotonsillar hypertrophy is a common condition in childhood, whose serious complications of pulmonary hypertension and cor pulmonale are devastating but local prevalence is unknown. This study determined the prevalence and associated factors of pulmonary hypertension in children with adenoid or adenotonsillar hypertrophy at Kenyatta National Hospital, Kenya.

Methods

This was a cross sectional hospital based survey conducted among children below 12 years of age with clinical and radiological adenoid hypertrophy attending the ear, nose and throat (ENT) outpatient clinic and general pediatric wards. Doppler echocardiography was used to determine pulmonary hypertension defined as a mean pulmonary arterial pressure (mPAP) of ≥25 mm Hg using the Chemla equation. Children with mPAP of ≥25 mm Hg were compared to those with lower pressures and clinical and radiological factors associated with pulmonary hypertension determined using multivariate logistic regression analysis.

Results

Of the 123 eligible children in the study, 27 had pulmonary hypertension giving a prevalence of 21.9% (95% CI 14.64%–29.27%). Independent factors associated with pulmonary hypertension included nasal obstruction (OR = 3.0 [95% CI 1.08–8.44] p = 0.035) and hyperactivity on history (OR = 0.2 [95% CI 0.07–0.59] p = 0.003) and adenoid-nasopharyngeal ratio (ANR) >0.825 on lateral neck radiography (OR = 5.0 [95% CI 1.01–24.37] p = 0.048).

Conclusion

One in five children with adenoid or adenotonsillar hypertrophy had pulmonary hypertension with a 3-fold and 5-fold increased odds in those with nasal obstruction on history and ANR >0.825 on lateral neck radiography respectively and an 80% reduced odds in reportedly hyperactive children.     

Prenatal consultation with the pediatric otolaryngologist

Objectives

To examine the spectrum of fetal head and neck anomalies that may prompt prenatal referral and to determine the frequency of these consultations.

Study design

Case series with chart review.

Methods

The billing databases of two urban pediatric otolaryngology practices were queried for ICD-9 codes corresponding to fetal anomalies between January 2010 and December 2012. The pediatric otolaryngology practices in this study evaluate all fetal head and neck anomalies referred to their respective institutions, including craniofacial disorders.

Results

Over a three-year period, 53 women presented for fetal otolaryngology consultation, with each practice seeing approximately one consultation every 6 weeks (every 5 weeks (JDS) and every 7 weeks (ARS)). The average maternal and gestational age at presentation were 28.7 years and 27.2 weeks, respectively. 83% of the cases (n = 44) involved some form of cleft lip with or without cleft palate. Other head and neck anomalies included fetal goiter/other congenital neck mass (9% (n = 5)) and micrognathia (6% (n = 3)). Macroglossia (n = 1) and facial cleft (n = 1) each accounted for 2% of cases. Cleft mothers presented earlier in pregnancy (average 26.8 weeks) than those with a neck mass (average 32.3 weeks) (p < 0.05). Only 3 cases (6%) merited ex utero intrapartum treatment.

Conclusions

Depending on the referral practices at a given medical center, craniofacial surgeons rather than pediatric otolaryngologists may be evaluating the majority of fetal head and neck anomalies, as orofacial clefts account for most prenatal consultations. The wide spectrum of congenital neck masses may or may not demand monitoring of the airway during the peripartum period.     

Feasibility and toxicity of concurrent chemoradiation for elderly patients with head and neck cancer

Objectives

Although concurrrent chemoradiation is increasingly used for patients with locally advanced head and neck cancer, many elderly patients receive radiation alone due to toxicity concerns. We evaluate acute and late toxicity among patients age ≥ 65 who received concurrent chemoradiation for head and neck cancer.

Design

Retrospective review.

Setting

Tertiary care center.

Participants

Between 6/2003 and 8/2011, 40 consecutive patients age ≥ 65 underwent combined chemoradiation for head and neck cancer. Ten patients were treated in the postoperative setting and 30 underwent definitive chemoradiation. Twenty-eight patients received concurrent platinum-based chemotherapy and 12 received concurrent weekly paclitaxel. Treatment plans were designed to provide a dose of 66–72 Gy at 2–2.12 Gy/fraction to > 95% of the gross tumor volume in the definitive setting or for positive margins and 60–66 Gy at 2 Gy/fraction post-operatively. Median follow-up was 23.2 months (range: 0–94.4 months).

Main outcomes measures

Acute skin and mucosal toxicity, unplanned treatment interruptions, and chronic treatment related toxicity including gastrostomy tube dependence as graded by the CTCAE v3.0.

Results

Eight patients (20%) required a radiation treatment break of ≥ 3 days. Thirteen (33%) required unplanned hospitalization during or immediately following treatment. No grade 4 + skin or mucosal toxicity was noted. Five patients remained PEG tube dependent at > 1 year. One patient developed non-healing mandibular osteoradionecrosis > 3 years following chemoradiation. The 2-year Kaplan–Meier estimate of overall survival was 55%.

Conclusion

Higher-than-expected rates of in-patient hospitalization with significant acute toxicity were noted in this cohort with a correspondingly high rate of radiation treatment breaks. Late toxicity rates were similar to those observed in historical controls with younger patients. Careful patient selection criteria should be employed for elderly patients considering concurrent chemoradiation for head and neck cancer.     

Predictors of accuracy in preoperative parathyroid adenoma localization using ultrasound and Tc-99 m-Sestamibi: A 4-quadrant analysis

Purpose

To compare the accuracy of preoperative parathyroid adenoma localization in patients with primary hyperparathyroidism (pHPT) due to a single adenoma using a detailed 4-quadrant analysis and to identify patient and tumor characteristics associated with accurate preoperative localization.

Materials and Methods

Retrospective review of 203 patients who underwent parathyroidectomy for pHPT due to a single adenoma between 2008 and 2011. Results from preoperative ultrasound and Tc-99 m-sestamibi were compared to operative findings to determine accuracy of localization studies. Associations between clinicopathologic features and accurate preoperative adenoma localization were evaluated.

Results

Ultrasound was performed on 198 patients, sestamibi on 177 patients, and both on 172 patients. Accurate localization occurred significantly more often for ultrasound than sestamibi (63% vs. 41%, P < 0.001). For ultrasound, accurate localization was found in patients with larger or heavier adenomas, those with adenomas located inferiorly, patients not having a reoperative procedure, and patients with higher post-operative serum calcium levels. For sestamibi, greater adenoma size or weight, adenomas located inferiorly, and patients with associated thyroid cancer on pathology were most predictive of accurate preoperative localization.

Conclusions

Our results provide evidence that ultrasound is more accurate in localizing parathyroid adenomas in patients with pHPT due to a single adenoma when compared to sestamibi scan using 4-quadrant location analysis and may be the preferred preoperative imaging modality in these patients. No significant preoperative patient factors were associated with accurate localization by ultrasound or sestamibi, but adenoma size, weight, and location in an inferior position were predictive of accurate preoperative localization.     

Nasal cavity dimensions in congenital pyriform aperture stenosis

Objective

To determine the dimensions of the nasal cavity in infants with congenital pyriform aperture stenosis (CPAS).

Study design

The nasal cavities of seven children with CPAS were identified and were compared to the nasal cavities of 13 neonates (<30 days old) who had received CT scans for other indications.

Methods

The width of the nasal cavities was measured at the pyriform aperture, choana, and at two standardized points along the lateral nasal wall (LW-1 and LW-2) between the pyriform aperture and choana.

Results

Comparison between neonates with and without CPAS demonstrates significant narrowing of the nasal cavity (not just the pyriform aperture) in infants with CPAS. Significantly smaller nasal width was noted at pyriform aperture, LW-1, and LW-2 (p < 0.01, p < 0.01, p = 0.02). No significant narrowing was seen at the choana.

Conclusion

These findings suggest that CPAS is associated with narrowing of the anterior 75% of the nasal cavity. This has implications for surgical management because simple pyriform aperture ostectomy may not be sufficient to relieve symptoms of obstruction.     

Clinical indicators that predict the presence of moderate to severe obstructive sleep apnea after adenotonsillectomy in children

Objective

To determine if clinical indicators can predict the presence of moderate to severe Obstructive Sleep Apnea (OSA) after Adenotonsillectomy (T&A) in children.

Study Design

Retrospective study.

Setting

Urban Tertiary Care Pediatric Hospital.

Methods

Parents of children (< 18 yrs.) with OSA completed a 55-item questionnaire based on their child’s symptoms at the time of preoperative polysomnography and then again at the follow up polysomnography completed 3 to 6 months after T&A.

Main outcome measures

55 item questionnaire, polysomnography variables.

Results

97 children were included (59 Male and 38 Female). The mean preoperative apnea hypopnea index (AHI) was 30.5 ± 31.6/h and the mean postoperative AHI was 4.4 ± 6.0/h. After T&A, all 97 children had reduction in AHI, and 35 (36.1%) no longer had OSA (AHI < 1/h). The total symptom scores decreased from 15.8 ± 9.4 to 11.3 ± 8.7 after T&A (p < .0001). Fourteen symptoms highly predictive of moderate to severe OSA were identified in the univariate analysis (p < 0.1). Using a cut-point of 4, this 14-item subscale illustrated an overall predictability of 72.2% (73.7% sensitivity and 70.0% specificity) for identifying children with moderate to severe OSA.

Conclusion

A cluster of 14 clinical sleep symptoms are highly predictive of moderate to severe OSA and can serve as clinical predictor for the presence of moderate to severe OSA after T&A.     

Elective neck management for high-grade salivary gland carcinoma

Purpose

To determine whether patients with clinically node negative (cNo) high grade salivary gland carcinomas benefit from an elective neck dissection prior to postoperative radiotherapy (RT).

Material/Methods

Between October 1964 and October 2009, 59 previously untreated patients with cNo high-grade salivary gland carcinomas (squamous cell carcinomas were excluded) were treated with curative intent using elective neck dissection (END; n = 41), or elective neck irradiation (ENI; n = 18) at the University of Florida College of Medicine (Gainesville, FL). All patients underwent resection of the primary cancer followed by postoperative RT. The median follow-up period was 5.2 years (range, 0.3–34 years).

Results

Occult metastases were found in 18 (44%) of the 41 patients in the END group. There were 4 recurrences (10%) in the END group and 0 recurrence in the ENI group. Neck control rates at 5 years were: END, 90%; ENI, 100%; and overall, 93% (p = 0.1879). Cause-specific survival was 94% in the ENI group, 84% in the END group, and 86% for all patients (p = 0.6998). There were 3 reported grade 3 or 4 toxicities. Two patients had a postoperative fistula and one patient had a grade 4 osteoradionecrosis that required a partial mandibulectomy.

Conclusions

Patients with cNo high grade salivary gland carcinomas who are planned to undergo surgery and postoperative RT likely do not benefit from a planned neck dissection.     

Epiglottic abscess as a complication of acute epiglottitis

Objective

An epiglottic abscess is considered a life-threatening medical situation that can cause death by obstruction the upper airways. We describe a 58-year-old man who presented to our hospital with sore throat, dysphagia and dysphonia.

Materials and methods

A fiberoptic laryngoscope (FOL) demonstrated beefy red edematous epiglottis with edema extending from the base of the tongue to the aryepiglottic folds and arytenoids. CT scan showed multiple air bubbles inside the swollen epiglottis, in keeping with the diagnosis of necrotizing epiglottic abscess.

Results

Under local anesthesia we performed puncture of the abscess at the tip of the epiglottis. He was dismissed 5 days from his admission to the hospital after an improvement was noticed in his epiglottis.

Conclusion

Treatment consists of airway management if needed under anesthesia and draining of the abscess. An IV antibiotics plus corticosteroids should be administrated the moment a suspicion of epiglottitis is present.     

Synovial sarcomas of the head and neck: Comparative analysis with synovial sarcoma of the extremities

Objective

This study analyzed synovial sarcoma (SS) of the head and neck in order to identify features associated with survival improvement and compared them with the survival of SS of limbs.

Methods

Clinical charts and histopathologic material with analysis for SYT/SSX gene rearrangement of 16 patients were reviewed. The clinicopathologic features and their association with survival were analyzed and compared with 174 SS of limbs.

Results

The average age was 24.2 years (range 21–86). Eight cases occurred in each sex. The most frequent site was the parapharyngeal space (PPS). The mean tumor size was 5.38 cm. Sixty-nine percent occurred in Stages II–III and 9% in Stage IV. Fifteen cases were excised: R0 resection in seven (46.7%) cases and R1 resection in eight (53.3%) cases. No patient with R0 resection has recurred, and three patients (37.5%) with R1 resection have recurred (p = 0.035). Patients with R0 surgery had better survival rates compared to those who received other treatments (p = 0.045). SS of head and neck showed a 5-year survival rate of 58% compared to 44.6% of the limbs (p = 0.450).

Conclusion

The most prevalent location was the PPS. Surgical resection with clear margins correlated with low recurrence. Head and neck sarcomas had similar survival rates compared to sarcomas of limbs.     

Thyroid carcinoma uptake of F-Fluorodeoxyglucose in patients with elevated serum thyroglobulin and negative I scintigraphy

Purpose

To determine if FDG-PET results can predict for outcome in thyroid cancer patients with elevated Tg and negative I-131 imaging.

Materials and methods

We conducted a retrospective review of 76 patients who had elevated serum Tg and negative ¹³¹I scintigraphy and who underwent FDG-PET. After FDG-PET, patients underwent neck dissection or radiation.

Results

The 51 patients with positive FDG-PET had a 5-year survival of 63% compared to 100% (p < 0.049) for the 25 patients with negative PET. Patients with FDG-avid disease isolated to the lymph nodes had 5-year CSS of 91% compared to 32% (p = 0.0033) for those with disease outside the regional lymph nodes. Twenty-nine patients with disease isolated to the regional lymph nodes underwent salvage neck dissection and 22 remain NED after 28 months.

Conclusions

Negative FDG-PET with elevated Tg predicts an excellent outcome. FDG-avid disease isolated to the regional lymph nodes had a low likelihood of death due to thyroid cancer.     

Multidisciplinary clinic care improves adherence to best practice in head and neck cancer

Purpose

Multidisciplinary team (MDT) care is widely accepted as best practice for patients with head and neck cancer, although there is little evidence that MDT care improves head and neck cancer related outcomes. This study aims to determine the impact of MDT care on measurable clinical quality indicators (CQIs) associated with improved patient outcomes.

Materials and methods

Patients treated for head and neck cancer at Ipswich Hospital from 2001 to 2008 were identified. Comparisons were made in adherence to CQIs between patients treated before (pre MDT) and after (post MDT) the introduction of the MDT. Associations were tested using the Chi-square and Whitney U-test.

Results

Treatment post MDT was associated with greater adherence to CQIs than pre MDT. Post MDT had higher rates of: dental assessment (59% versus 22%, p < .0001), nutritional assessment (57% versus 39%, p = .015), PET staging (41% versus 2%, p < .0001), chemo-radiotherapy (CRT) for locally advanced disease (66% versus 16%, p < .0001) and use of adjuvant CRT for high risk disease (49% versus 16%, p < .0001). The interval between surgery and radiotherapy was shorter in the post MDT group (p = .009) as was the mean length of hospitalization (p = .002).

Conclusions

This study highlights the measurable advantages of MDT care over the standard, less formalized, referral process.
