    IMPORTANCE: Controversy exists regarding management of the clinically node-negative neck in patients with recurrent larynx or hypopharynx cancers who received total laryngectomy after definitive radiation with or without chemotherapy. OBJECTIVE: To explore clinical and oncologic outcomes after elective neck dissection vs observation in patients who received clinically node-negative salvage total laryngectomy. DESIGN, SETTING, AND PARTICIPANTS: This cohort study was performed from January 2009 to June 2021 at a single, high-volume tertiary care center. Follow-up was conducted through June 2021 for all patients. Survival outcomes were based on at least 2 years of follow-up. Patients aged 18 years or older with recurrent, clinically node-negative larynx or hypopharynx tumors after definitive nonsurgical treatment who were treated with a salvage total laryngectomy were included. Data were analyzed from October 2021 through September 2022. EXPOSURES: Elective neck dissection. MAIN OUTCOMES AND MEASURES: Presence and location of occult nodal metastasis in electively dissected necks, along with differences in fistula rates and overall and disease-free survival between patients receiving elective neck dissection vs observation. RESULTS: Among 107 patients receiving clinically node-negative salvage total laryngectomy (median [IQR] age, 65.0 [57.8-71.3] years; 91 [85.0%] men), 81 patients underwent elective neck dissection (75.7%) and 26 patients underwent observation (24.3%). Among patients with elective neck dissection, 13 patients had occult nodal positivity (16.0%). Recurrent supraglottic (4 of 20 patients [20.0%]) or advanced T classification (ie, T3-T4; 12 of 61 patients [19.7%]) had an occult nodal positivity rate of 20% or more, and positive nodes were most likely to occur in levels II and III (II: 6 of 67 patients [9.0%]; III: 6 of 65 patients [9.2%]; VI: 3 of 44 patients [6.8%]; IV: 3 of 62 patients [4.8%]; V: 0 of 4 patients; I: 0 of 18 patients). There was a large difference in fistula rate between elective neck dissection (12 patients [14.8%]) and observed (8 patients [30.8%]) groups (difference, 16.0 percentage points; 95% CI, -3.4 to 35.3 percentage points), while the difference in fistula rate was negligible between 50 patients undergoing regional or free flap reconstruction (10 patients [20.0%]) vs 57 patients undergoing primary closure (10 patients [17.5%]) (difference, 2.5 percentage points; 95% CI, -12.4 to 17.3 percentage points). Undergoing elective neck dissection was not associated with a clinically meaningful improvement in overall or disease-free survival compared with observation. Recurrent hypopharynx subsite was associated with an increased risk of death (hazard ratio, 4.28; 95% CI, 1.81 to 10.09) and distant recurrence (hazard ratio, 7.94; 95% CI, 2.07 to 30.48) compared with glottic subsite. CONCLUSIONS AND RELEVANCE: In this cohort study, patients with recurrent supraglottic or advanced T classification tumors had an increased occult nodal positivity rate, elective neck dissection was not associated with survival, and patients with recurrent hypopharynx subsite were more likely to have a distant recurrence and die of their disease. These findings suggest that underlying disease pathology rather than surgical management may be associated with survival outcomes in this population

    Introduction As a result of the increased use of radiotherapy (RT) and improved long-term overall survival of patients with cancers of the head and neck (HN), the frequency of radiation-induced sarcomas of the head and neck (RISHN) may be increasing. The main objective of this systematic review was to determine the existing evidence on the frequency, treatment, and outcome of RISHN. Methods Using PRISMA guidelines we conducted a systematic review of the literature published from 2000 to 2020. Results Our review includes data of 560 patients from 64 articles. The total frequency of RISHNs among the reviewed series was 0.15%. The most frequent location of the primary tumor treated by RT was the nasopharynx. The mean RT dose used was 62 Gy, mean latency interval between irradiation and occurrence of RISHN was 11.1 years, and the most common RISHN location was the sinonasal region. Osteosarcoma was the principal histology, followed by fibrosarcoma. Surgery was the most frequently applied treatment modality. Of all patients with RISHN, 40.7% died of this disease after a mean interval of 13.9 months. Conclusions Notwithstanding the increased use of RT, the number of reported RISHNs has not increased substantially during the past two decades. Surgery with wide margins forms the best therapeutic option for these cases, but the outcome remains poor.Peer reviewe

    ACR appropriateness criteriaÂź nasal cavity and paranasal sinus cancers

    The American College of Radiology (ACR) Appropriateness Criteria are evidence‐based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer‐reviewed journals and the application of well‐established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Here, we present the Appropriateness Criteria for cancers arising in the nasal cavity and paranasal sinuses (maxillary, sphenoid, and ethmoid sinuses). This includes clinical presentation, prognostic factors, principles of management, and treatment outcomes. Controversies regarding management of cervical lymph nodes are discussed. Rare and unusual nasal cavity cancers, such as esthesioneuroblastoma and sinonasal undifferentiated carcinomas, are included. © 2016 American College of Radiology.

    The Selective Role of Open and Endoscopic Approaches for Sinonasal Malignant Tumours

    Endoscopic endonasal surgery has been demonstrated to be effective in the treatment of selected cases of sinonasal cancers. However, in cases of locally advanced neoplasms, as well as recurrences, the most appropriate approach is still debated. The present review aims to summarize the current state of knowledge on the utility of open approaches to resect sinonasal malignant tumours. Published comparative studies and meta-analyses suggest comparable oncological results with lower morbidity for the endoscopic approaches, but selection biases cannot be excluded. After a critical analysis of the available literature, it can be concluded that endoscopic surgery for selected lesions allows for oncologically safe resections with decreased morbidity. However, when endoscopic endonasal surgery is contraindicated and definitive chemoradiotherapy is not appropriate, craniofacial and transfacial approaches remain the best therapeutic option.Peer reviewe

    The purpose of this study was to determine the negative predictive value (NPV) of a 12- to 14-wk posttreatment PET/CT for 2-y progression-free survival (PFS) and locoregional control (LRC) in patients with p16-positive locoregionally advanced oropharyngeal cancer (LA-OPC). Study was a secondary endpoint in NRG-HN002, a noncomparative phase II trial in p16-positive LA-OPC, stage T1-T2, N1-N2b or T3, N0-N2b, and ≀10 pack-year smoking. Patients were randomized in a 1:1 ratio to reduced-dose intensity-modulated radiotherapy (IMRT) with or without cisplatin. Methods: PET/CT scans were reviewed centrally. Tumor response evaluations for the primary site, right neck, and left neck were performed using a 5-point ordinal scale (Hopkins criteria). Overall scores were then assigned as negative, positive, or indeterminate. Patients with a negative score for all 3 evaluation sites were given an overall score of negative. The hypotheses were NPV for PFS and LRC at 2-y posttreatment ≀ 90% versus \u3e90% (1-sided P value, 0.10). Results: A total of 316 patients were enrolled, of whom 306 were randomized and eligible. Of these, 131 (42.8%) patients consented to a posttherapy PET/CT, and 117 (89.3%) patients were eligible for PET/CT analysis. The median time from the end of treatment to PET/CT scan was 94 d (range, 52–139 d). Estimated 2-y PFS and LRC rates in the analysis subgroup were 91.3% (95% CI, 84.6, 95.8%) and 93.8% (95% CI, 87.6, 97.5%), respectively. Posttreatment scans were negative for residual tumor for 115 patients (98.3%) and positive for 2 patients (1.7%). NPV for 2-y PFS was 92.0% (90% lower confidence bound [LCB] 87.7%; P = 0.30) and for LRC was 94.5% (90% LCB 90.6%; P = 0.07). Conclusion: In the context of deintensification with reduced-dose radiation, the NPV of a 12- to 14-wk posttherapy PET/CT for 2-y LRC is estimated to be \u3e90%, similar to that reported for patients receiving standard chemoradiation. However, there is insufficient evidence to conclude that the NPV is \u3e90% for PFS

    Transoral resection of pharyngeal cancer: Summary of a National Cancer Institute Head and Neck Cancer Steering Committee Clinical Trials Planning Meeting, November 6–7, 2011, Arlington, Virginia

    Full text link
    Recent advances now permit resection of many pharyngeal tumors through the open mouth, an approach that can greatly reduce the morbidity of surgical exposure. These transoral techniques are being rapidly adopted by the surgical community and hold considerable promise. On November 6–7, 2011, the National Cancer Institute sponsored a Clinical Trials Planning Meeting to address how to further investigate the use of transoral surgery, both in the good prognosis human papillomavirus (HPV)–initiated oropharyngeal cancers, and in those with HPV‐unrelated disease. The proceedings of this meeting are summarized. © 2012 Wiley Periodicals, Inc. Head Neck, 2012Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/94490/1/23136_ftp.pd
