RESUMO

BACKGROUND: The authors hypothesized that unilateral intensity-modulated radiotherapy (IMRT) would decrease toxicity compared with bilateral IMRT for patients with lateralized palatine tonsillar cancer and a neck classification of N0 to N2b, with similar oncological outcomes. METHODS: A total of 154 patients were treated with postoperative IMRT from 1997 through 2013. Data were collected prospectively from 2005 to 2013 and retrospectively collected before 2005. Of those patients with lateralized primary and N0 to N2b disease, 48 received unilateral IMRT (group 1) and 59 received bilateral IMRT (group 2); a total of 47 patients had nonlateralized primary or N2c to N3 disease and received bilateral IMRT (group 3). RESULTS: The median follow-up was 5.5 years. The 5-year locoregional control rates were similar in group 1, group 2, and group 3 (100%, 96%, and 94%, respectively; pooled comparison: P = .39 and group 1 vs group 2 comparison: P = .19). The 5-year overall survival rates were similar in group 1, group 2, and group 3 (85%, 79%, and 76%, respectively; pooled comparison: P = .60 and group 1 vs group 2 comparison: P = .25). There were no contralateral neck recurrences noted among unilaterally treated patients. Unilateral IMRT reduced acute toxicity and improved patient-reported quality of life compared with bilateral IMRT. CONCLUSIONS: Unilateral IMRT appears to reduce acute toxicity and achieves oncological outcomes similar to those of bilateral IMRT in selected patients with lateralized palatine tonsillar cancer with a neck classification of N0 to N2b.

RESUMO

BACKGROUND: With the rise of oropharyngeal squamous cell carcinoma associated with human papillomavirus (HPV), appropriate treatment strategies continue to be tailored toward minimizing treatment while preserving oncologic outcomes. This study aimed to compare the outcomes for those undergoing transoral resection with or without adjuvant therapy for HPV-related oropharyngeal carcinoma. METHODS: A case-match cohort analysis was performed at two institutions on patients with HPV-related oropharyngeal squamous cell carcinoma. All the subjects underwent transoral surgery and neck dissection. The patients treated with surgery alone were matched 1:1 to those treated with surgery and adjuvant therapy using two groups identified as confounders: T-stage (T1/2 or T3/4) and number of pathologically positive lymph nodes (≤4 or >4). RESULTS: The study identified 105 matched pairs, with a median follow-up period of 42 months (range 3.1-102.3 months). The patients were staged as T1/T2 (86%) or T3/4 (14%). Each group had five patients with more than four positive lymph nodes. Adjuvant therapy significantly improved disease-free survival (hazard ratio [HR] 0.067; 95% confidence interval [CI] 0.01-0.62) and was associated with a lower risk of local and regional recurrence (risk ratio [RR] 0.096; 95% CI 0.02-0.47). No difference in disease-specific survival (HR 0.22; 95% CI 0.02-2.57) or overall survival (HR 0.18; 95% CI 0.01-2.4) was observed with the addition of adjuvant therapy. The risk of the gastrostomy tube was higher for those receiving adjuvant therapy (RR 7.3; 95% CI 2.6-20.6). CONCLUSIONS: Transoral surgery is an effective approach for the treatment of HPV-related oropharyngeal carcinoma. The addition of adjuvant therapy appears to decrease the risk of recurrence and improve disease-free survival but may not significantly improve overall survival.

RESUMO

PURPOSE: Pharyngocutaneous fistula (PCF) after laryngectomy continues to be a serious complication, especially after radiation. Recruitment of non-radiated tissue into the surgical defect may decrease the risk of fistula. These techniques however have significant morbidity and increases operative time. We hypothesized that using acellular dermal graft to reinforce the pharyngeal closure could decrease the risk of fistula, without the added morbidity of a vascularized flap. METHODS: We performed a retrospective chart review of all patients that underwent a laryngectomy between 2005 and 2015 at an acedemic tertiary referral center. Patients who underwent primary pharyngeal closure with Alloderm® reinforcement without any other flap reconstruction were identified. Basic demographics, previous treatment, operative technique and fistula were extracted from the medical records. The primary outcome was PCF rate. The time to closure, margin status and disease recurrence was also evaluated. RESULTS: Among 16 patients with AlloDerm® augmentation, eight had primary laryngectomy and eight had salvage laryngectomy. A total of three in the salvage laryngectomy with prior history of radiation developed PCF. The fistula closed in all three cases with conservative treatment. There was no PCF in the primary laryngectomy group without prior history of radiation. CONCLUSION: The rate of PCF among the salvage laryngectomy group with previous radiation did not differ from historical data. AlloDerm® can however, provide a simple alternative for repair in radiation patients where flap cannot be performed for pharyngeal reconstruction. In non-radiated patients, AlloDerm® augmentation may have a protective effect on fistula formation.

RESUMO

PURPOSE: The most common surgical method to remove benign parotid tumors remains the prograde approach. We examined if a retrograde surgical technique offers better outcomes than historical prograde controls. MATERIALS AND METHODS: A retrospective chart review at Stanford Hospital was conducted to identify retrograde parotidectomies between February 2012 and October 2014 that were staffed by the senior author (DS) with resident involvement. Facial nerve (FN) outcomes and other post-surgical parameters were recorded. RESULTS: We identified 44 consecutive cases and found that 18.2% (n=8) of patients experienced temporary paresis and 2.3% (n=1) experienced minor (HB 2) permanent paresis limited to one branch. The average hospital length of stay was 0.64 days and complication rate was 6.8%. CONCLUSION: The retrograde technique has complication rates comparable to historical rates for the prograde technique and is amenable to minimally invasive outpatient superficial parotidectomy.

RESUMO

The National Comprehensive Cancer Network (NCCN) describes the presence of extracapsular spread and/or positive margins in oropharynx cancer (OPC) as an indication for the addition of chemotherapy to postoperative radiation. The guideline's category 1 consensus is based on what they term high-level evidence. For this study, the authors performed a critical appraisal of the research upon which the NCCN guideline is based and assessed its relevance in the era of human papillomavirus (HPV)/p16-positive OPC. Multiple shortcomings were identified, including patient exclusion after randomization and the use of unplanned subgroup analyses without multivariate adjustment, which undermined internal validity. Indeterminate HPV/p16 status limited external validity. Given the unique biology of HPV/p16-positive tumors and the problems of internal and external validity, the authors concluded that the literature upon which the recommendation for the addition of chemotherapy to adjuvant radiation was based does not generate high-level evidence, and its relevance for the postoperative management of patients with HPV/p16-positive OPC remains unknown.

RESUMO

These NCCN Guidelines Insights focus on recent updates to the 2015 NCCN Guidelines for Head and Neck (H&N) Cancers. These Insights describe the different types of particle therapy that may be used to treat H&N cancers, in contrast to traditional radiation therapy (RT) with photons (x-ray). Research is ongoing regarding the different types of particle therapy, including protons and carbon ions, with the goals of reducing the long-term side effects from RT and improving the therapeutic index. For the 2015 update, the NCCN H&N Cancers Panel agreed to delete recommendations for neutron therapy for salivary gland cancers, because of its limited availability, which has decreased over the past 2 decades; the small number of patients in the United States who currently receive this treatment; and concerns that the toxicity of neutron therapy may offset potential disease control advantages.

RESUMO

PURPOSE: The clinical benefit of combined intraoperative magnetic resonance imaging (iMRI) and endoscopy for transsphenoidal pituitary adenoma resection has not been completely characterized. This study assessed the impact of microscopy, endoscopy, and/or iMRI on progression-free survival, extent of resection status (gross-, near-, and sub-total resection), and operative complications. METHODS: Retrospective analyses were performed on 446 transsphenoidal pituitary adenoma surgeries at a single institution between 1998 and 2012. Multivariate analyses were used to control for baseline characteristics, differences during extent of resection status, and progression-free survival analysis. RESULTS: Additional surgery was performed after iMRI in 56/156 cases (35.9%), which led to increased extent of resection status in 15/156 cases (9.6%). Multivariate ordinal logistic regression revealed no increase in extent of resection status following iMRI or endoscopy alone; however, combining these modalities increased extent of resection status (odds ratio 2.05, 95% CI 1.21-3.46) compared to conventional transsphenoidal microsurgery. Multivariate Cox regression revealed that reduced extent of resection status shortened progression-free survival for near- versus gross-total resection [hazard ratio (HR) 2.87, 95% CI 1.24-6.65] and sub- versus near-total resection (HR 2.10; 95% CI 1.00-4.40). Complication comparisons between microscopy, endoscopy, and iMRI revealed increased perioperative deaths for endoscopy versus microscopy (4/209 and 0/237, respectively), but this difference was non-significant considering multiple post hoc comparisons (Fisher exact, p = 0.24). CONCLUSIONS: Combined use of endoscopy and iMRI increased pituitary adenoma extent of resection status compared to conventional transsphenoidal microsurgery, and increased extent of resection status was associated with longer progression-free survival. Treatment modality combination did not significantly impact complication rate.

RESUMO

BACKGROUND: Radiation treatment volumes in head and neck squamous cell carcinoma (HNSCC) are controversial. The authors report the outcomes, patterns of failure, and quality of life (QOL) of patients who received treatment for HNSCC using intensity-modulated radiation therapy (IMRT) that eliminated the treatment of contralateral retropharyngeal lymph nodes (RPLNs) in the clinically uninvolved neck. METHODS: A prospective institutional database was used to identify patients who had primary oral cavity, oropharyngeal, hypopharyngeal, laryngeal, and unknown primary HNSCC for which they received IMRT. There were 3 temporal groups (generations 1-3). Generation 1 received comprehensive neck IMRT with parotid sparing, generation 2 eliminated the contralateral high level II (HLII) lymph nodes, and generation 3 further eliminated the contralateral RPLNs in the clinically uninvolved neck. Patterns of failure and survival analyses were completed, and QOL data measured using the MD Anderson Dysphagia Inventory were compared in a subset of patients from generations 1 and 3. RESULTS: In total, 748 patients were identified. Of the 488 patients who received treatment in generation 2 or 3, 406 had a clinically uninvolved contralateral neck. There were no failures in the spared RPLNs (95% confidence interval, 0%-1.3%) or in the high contralateral neck (95% confidence interval, 0%-0.7%). QOL data were compared between 44 patients in generation 1 and 51 patients in generation 3. QOL improved both globally and in all domains assessed for generation 3, in which reduced radiotherapy volumes were used (P < .007). CONCLUSIONS: For patients with locally advanced HNSCC, eliminating coverage to the contralateral HLII lymph nodes and contralateral RPLNs in the clinically uninvolved side of the neck is associated with minimal risk of failure in these regions and significantly improved patient-reported QOL.

RESUMO

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers focuses on glottic laryngeal cancer, which is the most common type of laryngeal cancer and has an excellent cure rate. The lymphatic drainage of the glottis is sparse, and early stage primaries rarely spread to regional nodes. Because hoarseness is an early symptom, most glottic laryngeal cancer is early stage at diagnosis. Updates to these guidelines for 2014 include revisions to "Principles of Radiation Therapy" for each site and "Principles of Surgery," and the addition of a new section on "Principles of Dental Evaluation and Management."

RESUMO

BACKGROUND: Extracapsular spread (ECS) is commonly used to justify adjuvant chemotherapy in patients with head and neck cancer. The role of ECS as a prognosticator and adjuvant therapy determinant in surgically resected, human papillomavirus-related oropharyngeal squamous cell carcinoma (OPSCC), however, has never been determined. METHODS: Of 210 oropharynx patients in a prospective transoral laser microsurgery database, 152 patients who had p16-positive primary OPSCC and pathologically positive necks were eligible for the study. ECS was measured from routine reporting (ECS(report)) and by using a novel histologic grading system (ECS(graded)). Proportional hazards models and matched analyses were used to compare the impact of ECS and adjuvant therapy on disease-free survival (DFS). Patients with and without graded ECS were matched for T-stage, surgical margins, and adjuvant therapy. RESULTS: At a median follow-up of 43 months, the presence of ECS was not associated with poorer DFS in multivariate analyses (ECS(report): hazard ratio [HR], 3.42; 95% confidence interval [CI], 0.45-25.88; P = .23; ECS(graded): HR, 2.54; 95% CI, 0.88-7.34; P = .09). T-stage and high-grade ECS, ie soft tissue metastasis (STM(graded)) were prognostic. Overall and in the presence of ECS or even STM, adjuvant CRT was not associated with better DFS over radiotherapy alone (HR, 0.25; 95% CI, 0.06-1.13; P = .07). In addition, matched analyses demonstrated no significant reduction in DFS for the presence of ECS versus the absence of ECS or reduced DFS for the administration of adjuvant radiotherapy alone versus CRT in ECS-positive patients. CONCLUSIONS: Routinely reported ECS was not prognostic in this study. Adjuvant CRT versus radiotherapy alone produced no improvement in DFS for ECS-positive patients. The authors propose that de-escalated adjuvant therapy should be considered for patients with p16-positive OPSCC who undergo surgery and that routinely reported ECS should not be used to justify adjuvant chemotherapy.

RESUMO

Extracapsular extension in squamous cell carcinoma nodal metastases usually predicts worse outcome. However, there are no standard histologic grading criteria for extracapsular extension, and there have been few studies on oropharyngeal squamous cell carcinoma alone. We studied the extent of extracapsular extension utilizing a novel grading system and correlated grades with outcomes while controlling for p16 status. A cohort of surgically treated oropharyngeal squamous cell carcinoma cases were reviewed and metastases graded as 0 (within substance of node), 1 (filling subcapsular sinus with thickened capsule/pseudocapsule, but no irregular peripheral extension), 2 (≤1 mm beyond capsule), 3 (>1 mm beyond capsule), or 4 (no residual nodal tissue or architecture; 'soft tissue metastasis'). There were 101 cases, for which p16 was positive in 90 (89%). Extracapsular extension grades did not correlate with nodal size (P=0.28) or p16 status (P=0.8). In follow up, 10 patients (10%) had disease recurrence with only 3 of 64 (5%) grade 0-3 cases and 7 of 37 (19%) with grade 4 recurring (P=0.04). Grade 4 extracapsular extension was associated with poorer survival (P<0.01). However, grade 4 extracapsular extension correlated with higher T-stage (P=0.02), and in multivariate analysis, was not significantly associated with poorer overall (P=0.14) disease-free (P=0.2), or disease-specific survival (P=0.09). The impact of extracapsular extension in nodal metastases is limited in oropharyngeal squamous cell carcinoma. Only extracapsular extension grade 4 associates with poorer outcomes, but not independently of T-stage and other variables.

RESUMO

OBJECTIVE: We observed high survival in a previous report of a p16-positive, oropharyngeal carcinoma (OPC) cohort treated primarily with transoral laser microsurgery (TLM) ± adjuvant therapy and followed for ≥ 12 months. To address long-term outcomes of primary transoral surgery for this unique disease, we present an updated analysis of our cohort with extended follow-up. METHODS: A prospectively assembled TLM cohort of 171 OPC patients was analyzed for disease-free, disease-specific, and overall survival (disease-free survival [DFS], disease-specific survival [DSS], overall survival [OS]) and functional outcomes, with a minimum follow-up of 60 months or to death. RESULTS: Median follow-up was 103 (60-201) months. Five-year DFS, DSS, and OS estimates were 85% (95% confidence interval [CI]: 80%-91%), 93% (95% CI: 89%-97%), and 90% (95% CI: 86%-95%). Recurrence occurred in 20 (12%; 7 locoregional, 13 distant); median time to recurrence was 18.8 months; and 90% occurred within 48 months. Age, smoking, American Joint Committee on Cancer 8th edition clinical tumor-category, pathologic tumor (pT)-category, pathologic tumor-node-metastasis (pTNM), and any adjuvant were significantly associated with disease-free survival in multivariable analyses, whereas pT-category, pN-category, TNM grouping, and angioinvasion were associated with DSS. A second primary developed in six (3.5%) patients. Indications for gastrostomy were recurrence/second primary (11), postadjuvant esophageal stenosis (6), comorbidities (3), and osteo/chondroradionecrosis (3); only seven (4%) had a gastrostomy tube in the absence of these factors, all of whom received adjuvant therapy. Two had a tracheostomy tube [chondoradionecrosis (1), recurrence (1)]. CONCLUSION: High 5-year survival and locoregional control were observed, with recurrence occurring more commonly as distant metastasis. The observed time to recurrence suggests posttreatment oncologic surveillance for at least 48 months. Identified prognosticators will inform adjuvant treatment considerations, trial planning, and patient counseling for long-term outcomes.

RESUMO

IMPORTANCE: The soft palate contributes to deglutition, articulation, and respiration. Current reconstructive techniques focus on restoration of both form and function. The unique challenges of soft palate reconstruction include maintenance of complex upper aerodigestive tract function, with minimal local or donor site morbidity. OBJECTIVE: To review the literature on soft palate reconstruction and present an algorithm on how to approach soft palate defects based on this review. EVIDENCE REVIEW: A review of the literature for articles reporting studies on and that described concepts related to soft palate reconstruction was conducted in March 2017. In all, 1804 candidate titles and abstracts were independently reviewed. English-language articles that discussed acquired soft palate defect reconstruction were included. Non-English language studies without available translations, studies on primary soft palate defect reconstruction (ie, cleft palate repair) and primary cleft palate repair, studies in which the soft palate was not the focus of the article, and studies involving animals were excluded. FINDINGS: The following observations were made from the review of 92 included articles. Soft palate anatomy is a complex interplay of multiple structures working in a 3-dimensional area. Three of the authors created an initial algorithmic framework based on the selected studies. After this, a round table discussion among 3 authors considered experts was used to refine the algorithm based on their expert opinion. The 4 most important factors were determined to be defect size, defect extension to other subsites, defect thickness, and history of radiotherapy or planned radiotherapy. This algorithm includes both surgical and nonsurgical options. Defects in the soft palate not only affect the size and shape of the organ but, more critically, the function. The reconstructive ladder is used to help maximize the remaining soft palate functional tissue and minimize the effect of nonfunctional implanted tissue. Partial-thickness defects or defects less than one-fourth of the soft palate may not require locoregional tissue transfer. Patients with a history of radiotherapy or defects of up to 75% of the soft palate may require locoregional tissue transfer. Defects greater than 75% of the soft palate, defects that include exposure of the neck vasculature, or defects that include significant portions of the hard palate or adjacent oropharyngeal subsites may require free tissue transfer. Obturation should be considered a second-line option in most cases. CONCLUSIONS AND RELEVANCE: Ideal reconstruction of the soft palate relies on a comprehensive understanding of soft palate anatomy, a full consideration of the armamentarium of surgical techniques, consideration for adjacent subsite deficits, and a detailed knowledge of various intrinsic and extrinsic patient factors to optimize speech, swallowing, and airway outcomes. The included algorithm may serve as a useful starting point for the surgeon when considering reconstruction.

RESUMO

The optimal management of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) with primary surgical versus non-surgical treatment is unclear. The objective of this systematic review was to evaluate the literature and compare survival for primary surgical versus non-surgical treatment of HPV-positive OPSCC. We performed a comprehensive literature search of multiple electronic databases for relevant articles up to February, 2017. Studies reporting mortality or hazard ratio (HR) for overall survival (OS) in primary HPV-positive OPSCC patients were eligible. Seventy-three articles were eligible, of which 66 included single-modality (19 surgical, 47 non-surgical), and 7 included both surgical and non-surgical modalities. There were no randomized studies comparing outcomes between both modalities. In a meta-analysis of both-modality studies, OS with surgical treatment was not significantly different from non-surgical treatment (pooled HR 1.12; 95% CI: 0.35, 3.57). There was significant heterogeneity between studies (I2 = 82.4%). Among single-modality studies, the mortality rate was lower with surgical [pooled proportion 0.15 (95% CI: 0.09, 0.21)] versus non-surgical treatment [0.20 (95% CI:0.15, 0.24)]. In a subgroup analysis, OS was higher for HPV-positive versus HPV-negative OPSCC, irrespective of the treatment modality. We conclude that there is an absence of high-quality studies that compare survival for HPV-positive OPSCC treated with primary surgical versus non-surgical approach. The available data suggest no statistical or clinically meaningful difference in survival between the two approaches. HPV-positivity was a key prognostic factor irrespective of treatment modality. Further high-quality studies with consistent data reporting are needed to inform the choice for optimal treatment modality for HPV-positive OPSCC.

RESUMO

BACKGROUND: Oncologic outcomes of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (SCC) requiring resection of major muscular or neurovascular tissue during neck dissection for invasive nodal disease remain uncertain. METHODS: Patients with HPV-related oropharyngeal SCC requiring resection of major muscular or neurovascular tissue during their neck dissections were retrospectively identified. RESULTS: Seventy-two patients were included. Regional and distant recurrences occurred in 6% and 17% of patients. Advanced T classification, pathological node number of 5 or more, and omission of adjuvant therapy were associated with decreased disease-free survival (DFS). The addition of adjuvant chemotherapy was not associated with improved survival. CONCLUSION: Patients with invasive nodal disease from HPV-related oropharyngeal SCC can be managed with up-front surgery and adjuvant therapy, as indicated with good regional control. Although distant recurrence was the primary site of failure, adjuvant chemotherapy was not associated with improved outcomes. The T classification, node number, and adjuvant radiotherapy are independent prognostic factors in this patient population.

RESUMO

BACKGROUND AND PURPOSE: Acute pain during weekly radiotherapy (RT) to the head and neck is not well characterized. We studied dose-volume metrics and clinical variables that are plausibly associated with throat or esophageal pain as measured with a weekly questionnaire during RT. MATERIALS AND METHODS: We prospectively collected weekly patient-reported outcomes from 122 head and neck cancer patients during RT. The pain score for each question consisted of a four-level scale: none (0), mild (1), moderate (2), and severe (3). Univariate and multivariate ordinal logistic regression analyses were performed to investigate associations between both esophageal and throat pain and clinical as well as dosimetric variables. RESULTS: In multivariate analysis, age was significantly associated with both types of pain, leading to odds ratio (OR) = 0.95 (p = 0.008) and OR = 0.95 (p = 0.007) for esophageal and throat pain, respectively. For throat pain, sex (OR = 4.12; p = 0.010), with females at higher risk, and fractional organ at risk (OAR) mean dose (OR = 3.30; p = 0.014) were significantly associated with throat pain. CONCLUSIONS: A fractional OAR mean dose of 1.1 Gy seems a reasonable cutoff for separating no or mild pain from moderate to severe esophageal and throat pain. Younger patients who received RT experienced more esophageal and throat pain. Females experienced more throat pain, but not esophageal pain.
