Long-Term Quality of Life After Total Laryngectomy and Postoperative Radiotherapy Versus Concurrent Chemoradiotherapy for Laryngeal Preservation

Objective: To compare the quality of life (QoL) of patients who underwent total laryngectomy with voice prosthesis insertion and postoperative radiotherapy (PORT) with those receiving concurrent chemoradiation for laryngeal preservation.

Long-term quality of life after treatment for locally advanced oropharyngeal carcinoma: Surgery and postoperative radiotherapy versus concurrent chemoradiation

The aim of this study was to evaluate the long-term quality of life (QoL) in survivors with oropharyngeal carcinoma (OC) treated with surgery and postoperative radiotherapy (PORT) versus concurrent chemoradiation (CRT) using the European Organization for Research and Treatment of Cancer QoL Questionnaires. The study group consisted of 57 patients. The scores for physical (P=0.043) and social (P=0.036) functioning were significantly more favorable in the chemoradiation group. Surgical patients showed statistically higher problems with fatigue (P=0.047), pain (P=0.027), swallowing (P=0.042), social eating (P=0.038) and social contact (P=0.002). CRT group reported significantly greater problems with teeth (P=0.049), open mouth (P=0.036), dry mouth (P=0.022) and sticky saliva (P=0.044). The global QoL score was higher in CRT group (P=0.027). These results support an organ preservation approach with CRT in patients with advanced OC. However, considering the absence of randomized trial comparing outcomes after surgical versus nonsurgical approaches, severe xerostomia following CRT, the higher postoperative morbidity in the setting of salvage surgery, future prospective clinical trials on greater samples of patients are needed to confirm our conclusions.

Submandibular space infection: a potentially lethal infection.

OBJECTIVES The aims of this study were to review the clinical characteristics and management of submandibular space infections and to identify the predisposing factors of life-threatening complications. DESIGN AND METHODS This was a retrospective study at a tertiary academic center. We retrieved and evaluated the records of all patients admitted to the University of Padua Otolaryngology Clinic at Treviso Regional Hospital with the diagnosis of submandibular space infection for the period 1998-2006. The following variables were reviewed: demographic data, pathogenesis, clinical presentation, associated systemic diseases, bacteriology, imaging studies, medical and surgical treatment, and complications. A multivariate logistic regression analysis was undertaken using a forward stepwise technique. RESULTS Multivariate analysis identified four risk factors for complications. Anterior visceral space involvement (odds ratio (OR) 54.44; 95% confidence interval (CI) 5.80-511.22) and diabetes mellitus (OR 17.46; 95% CI 2.10-145.29) were the most important predictive factors in the model. Logistic regression analysis also confirmed other comorbidities (OR 11.66; 95% CI 1.35-100.10) and bilateral submandibular swelling (OR 10.67; 95% CI 2.73-41.75) as independent predictors for life-threatening complications. CONCLUSIONS Airway obstruction and spread of the infection to the mediastinum are the most troublesome complications of submandibular space infections. Therefore, the maintenance of a secure airway is paramount. Patients with cellulitis and small abscesses can respond to antibiotics alone. Surgical drainage should be performed in patients with larger abscesses, Ludwigs angina, anterior visceral space involvement, and in those who do not respond to antibiotic treatment. Moreover, the clinical assessment in patients with comorbidities, especially diabetes mellitus, requires a high level of suspicion for potential life-threatening complications. Early surgical drainage should always be considered in these patients, even in seemingly less critical cases.

Conservative management of deep neck abscesses in adults: The importance of CECT findings

OBJECTIVES: To review cases of DNAs with special emphasis on contrast-enhanced computed tomography (CECT) findings and their implications for treatment planning. STUDY DESIGN AND SETTINGS: Retrospective evaluation of adult patient records with diagnosis of DNAs on CECT at Treviso Regional Hospital. RESULTS: Eighty patients were identified. In 30.0% of cases, an immediate surgical drainage was performed. In 22.5% of cases, a surgical drainage was necessary because of the lack of clinical response to medical therapy alone. Almost half of the patients were treated with antibiotics alone with complete remission. DM was predictive for lack of response to medical therapy alone (P = 0.014). Intraoperative findings confirmed the CECT diagnosis in 88.1%. CONCLUSIONS: Although the mainstay of treatment for deep neck abscesses remains surgical drainage, small abscesses can respond to antibiotics alone. CECT monitoring of DNAs was the essential steps in choosing the more appropriate treatment and, probably, the basis for the good prognosis of patients.

Laryngeal tuberculosis: an often forgotten diagnosis

OBJECTIVE Clinical description of laryngeal tuberculosis. METHODS Clinical case review. RESULTS The authors report three cases of laryngeal tuberculosis with lung involvement in HIV-negative patients; symptoms were mostly laryngeal. Diagnosis was made in all cases through laryngeal biopsy and examination of the sputum. Patients fully recovered after being given standard antituberculosis therapy. CONCLUSIONS Laryngeal tuberculosis almost disappeared after the 1950s, but, concomitant with the increase in pulmonary forms, may still be found and, being uncommon, is often misdiagnosed.

Carcinoma Metastatic to Cervical Lymph Nodes From an Occult Primary Tumor: The Outcome After Combined-Modality Therapy

BackgroundThe aim of this retrospective analysis was to analyze the results of treatment of patients with cervical node metastases from carcinoma of occult primary with a policy including neck dissection and postoperative comprehensive radiotherapy.MethodsNinety patients were treated with curative intent from 1990 to 2002.ResultsThe actuarial rate of neck disease control was 68.8% at 5 years (95% confidence interval [CI], 58.9%–78.7%). On multivariate analysis, the rate of neck disease control was significantly related to lymph nodal metastatic level (P = .006). The actuarial rate of developing head and neck primary tumors at 5 years was 8.9% (95% CI, 2.6%–15.2%). The 5-year actuarial rate of distant metastases was 19.1% (95% CI, 9.4%–28.9%). In multivariate analysis, a statistically significant difference in the rate of distant metastasis was obtained when patients were stratified according to the level of nodal involvement (P = .01) and the presence of extracapsular extension (P = .013). At the time of analysis, 50 of the 90 patients were alive. A total of 32 (35.6%) had died from causes related to their primary disease. Actuarial disease-specific survival at 2 and 5 years was 73.6% (95% CI, 64.3%–82.9%) and 62.8% (95% CI, 51.9%–73.7%), respectively. In multivariate analysis, a statistically significant difference in disease-specific survival was obtained when patients were stratified according to the level of nodal involvement and the presence of extracapsular extension.ConclusionsOur study seems to support the use of combined-modality therapy in patients with neck metastases from carcinoma of occult primary. However, in the absence of randomized trials, comprehensive irradiation cannot be routinely advised.

Cervical lymph node metastases from occult squamous cell carcinoma : Analysis of 82 cases

Purpose: The aim of this study was to analyze the prognostic value of some clinical factors and to compare the survival of different treatment plans in patients with cervical lymph node metastases from occult squamous cell carcinoma (SCC). Methods: A retrospective review was conducted of patients who were diagnosed as having cervical lymph node metastases from occult SCC. Overall cumulative survival was analyzed using the standard Kaplan-Meier method. Tests of significance were based on log-rank statistics. Results: The 82 patients in the study consisted of 69 males (84.2%) and 13 females (15.8%). The average age at diagnosis was 64.7 years. Fifty patients (60.9%) underwent surgical treatment of cervical metastasis. Radiotherapy was performed in 79 patients. Thirty-two patients (40.5%) received primary fractioned external beam radiotherapy; 47 patients (59.5%) received postoperative fractioned external beam radiotherapy. Ipsilateral radiotherapy was performed on 37 patients (46.8%), bilateral neck plus mucosal irradiation was performed in 42 patients (53.2%). Ten patients (12.2%) developed a primary tumor during the follow-up. The actuarial survival rates of all patients 2, 5 and 10 years after diagnosis were 50.9, 25.3 and 18.5%, respectively. Patients with nodal stage N2b, N2c and N3 had a significantly poorer prognosis than those with nodal stage N1 and N2a (p = 0.0239). The survival in patients with metastatic nodes in the supraclavicular region (level IV) was significantly poorer than that of patients with involvement of the upper-middle jugular lymph nodes (p = 0.0003). We observed a statistically significant better survival in patients receiving bilateral neck plus mucosal irradiation (p = 0.0003). Conclusions: Initial N-category and metastasis localization were the most important prognostic factors and nodal relapse the major cause of treatment failure, thus optimal management of cervical nodes appears crucial for the success of treatment. Patients receiving bilateral neck plus mucosal irradiation had a higher survival rate than those who received ipsilateral irradiation.

Telomere shortening in mucosa surrounding the tumor: Biosensor of field cancerization and prognostic marker of mucosal failure in head and neck squamous cell carcinoma

OBJECTIVES The aim of the present study was to investigate the pattern of telomere length and telomerase expression in cancer tissues and the surrounding mucosa (SM), as markers of field cancerization and clinical outcome in patients successfully treated for with head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS This investigation was a prospective cohort study. Telomere length and levels of telomerase reverse transcriptase (TERT) transcripts were quantified by real-time PCR in cancer tissues and SM from 139 and 90 patients with HNSCC, respectively. RESULTS No correlation was found between age and telomere length in SM. Patients with short telomeres in SM had a higher risk of mucosal failure (adjusted HR=4.29). Patients with high TERT levels in cancer tissues had a higher risk of regional failure (HR=2.88), distant failure (HR=7.27), worse disease-specific survival (HR for related death=2.62) but not mucosal failure. High-risk patients having both short telomeres in SM and high levels of TERT in cancer showed a significantly lower overall survival (HR=2.46). CONCLUSIONS Overall these findings suggest that telomere shortening in SM is a marker of field cancerization and may precede reactivation of TERT. Short telomeres in SM are strongly prognostic of mucosal failure, whereas TERT levels in cancer tissues increase with the aggressiveness of the disease and are prognostic of tumor spread.

MATCHED SURVIVAL ANALYSIS IN PATIENTS WITH LOCOREGIONALLY ADVANCED RESECTABLE OROPHARYNGEAL CARCINOMA: PLATINUM-BASED INDUCTION AND CONCURRENT CHEMORADIOTHERAPY VERSUS PRIMARY SURGICAL RESECTION

PURPOSE The outcome of a prospective case series of 47 patients with newly diagnosed resectable locoregionally advanced oropharyngeal squamous cell carcinoma treated with platinum-based induction-concurrent chemoradiotherapy (IC/CCRT) was compared with the outcome of 47 matched historical control patients treated with surgery and postoperative RT. METHODS AND MATERIALS A total of 47 control patients with locoregionally advanced oropharyngeal squamous cell carcinoma were identified from review of a prospectively compiled comprehensive computerized head-and-neck cancer database and were matched with a prospective case series of patients undergoing IC/CCRT by disease stage, nodal status, gender, and age (± 5 years). The IC/CCRT regimen consisted of one cycle of induction chemotherapy followed by conventionally fractionated RT to a total dose of 66-70 Gy concomitantly with two cycles of chemotherapy. Each cycle of chemotherapy consisted of cisplatinum, 100 mg/m(2), and a continuous infusion of 5-fluorouracil, 1,000 mg/m(2)/d for 5 days. The survival analysis was performed using Kaplan-Meier estimates. Matched-pair survival was compared using the Cox proportional hazards model. RESULTS No significant difference was found in the overall survival or progression-free survival rates between the two groups. The matched analysis of survival did not show a statistically significant greater hazard ratio for overall death (hazard ratio, 1.35; 95% confidence interval, 0.65-2.80; p = .415) or progression (hazard ratio, 1.44; 95% confidence interval, 0.72-2.87; p = .301) for patients undergoing IC/CCRT. CONCLUSION Although the sample size was small and not randomized, this matched-pair comparison between a prospective case series and a historical cohort treated at the same institution showed that the efficacy of IC/CCRT with salvage surgery is as good as primary surgical resection and postoperative RT.

Pattern of lymph node metastases in squamous cell carcinoma of the tonsil : Implication for selective neck dissection

The aim of this study was to prospectively analyze the distribution of neck metastases and the outcome in patients surgically treated for tonsillar carcinoma in order to deduce implications for selective neck dissection. The criteria for inclusion in the study were (1) previously untreated, histologically proven, resectable squamous cell carcinoma of the tonsil, (2) curative surgical intent on the primary tumor and neck, (3) no history of prior head and neck cancer, (4) absence of synchronous second primary in the upper aerodigestive tract, lung and esophagus, (5) absence of distant metastases. Fifty-eight previously untreated consecutive patients with tonsillar squamous cell carcinoma were included in this prospective study. Among 22 patients with clinically negative cervical lymph nodes, 4 patients (18.2%) had metastatic lymph nodes on pathologic examination. Occult node metastases were mainly located in ipsilateral II level. No occult metastases occurred at levels I and V. Among 36 patients with clinically positive cervical lymph nodes, 3 patients (8.3%) had an occult pathologic metastatic involvement of cervical lymph nodes of ipsilateral level V. Level I was free of lymph node metastases. Clinical N category >N2a (p=0.003), nodal metastases to levels III (p=0.026) and IV (p=0.009) were significantly related to level V nodal metastases. The 2 and 5 years actuarial disease-free survival was 82.7% (95% CI 71.2-93.5%) and 58.3% (95% CI 36.7-79.9%), respectively. The actuarial recurrence-free survival was 87.9% (95% CI 78.9-96.8%) and 72.2% (95% CI 53.9-90.5%) at 2 and 5 years, respectively. Our findings support the role of a selective lateral neck dissection in the management of clinically N0 necks and in selected N+ necks (N1 and N2a disease located at level II) in patients with tonsillar carcinoma without oral involvement.
