FGD-PET/CT three months after (chemo)radiotherapy for head and neck squamous cell carcinoma spares considerable number of patients from a salvage neck dissection. Radiother Oncol 2024; 198:110407. [PMID: 38942119 DOI: 10.1016/j.radonc.2024.110407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2024] [Revised: 06/12/2024] [Accepted: 06/17/2024] [Indexed: 06/30/2024]
Abstract
PURPOSE In the last decades FDG-PET/CT is increasingly used in combination with the standard diagnostic modalities (MRI + US-FNA) to identify residual neck disease (RND) after (chemo)radiotherapy for head-and-neck squamous cell carcinoma (HNSCC). The purpose of the current study is to identify the impact of increasing use of FDG-PET/CT on the accuracy of patient selection for salvage neck dissection (SND). MATERIALS AND METHODS Between 2008 and 2022, 908 consecutive patients with node-positive HNSCC were treated with (chemo)radiotherapy in our institution. PRIMARY ENDPOINT positive predictive value (PPV) of FDG-PET/CT for pathologic-confirmed RND (pRND) after SND, compared to the standard of care; MRI + US-FNA. Secondary endpoints: oncologic outcomes. RESULTS Of the entire group, 130 patients (14 %) received SND. Of them only 53 patients (41 %) had pRND at the SND-specimens. The PPV of FDG-PET/CT for the detection of pRND was considerably better, compared to MRI + US-FNA; 89 % and 65 %, respectively. If FDG-PET/CT showed metabolic CR, these patients did not undergo SND. The NPV was 97.5 %, as only 2.5 % of these patients developed delayed regional failure. FDG-PET/CT considerably improved the accuracy of patient selection for SND, as significantly more patients treated in the second period, compared to first period of the study (n = 454 each) still had vital tumor at SND-specimen (53 % and 31 %, p = 0.008). Regional recurrence free-survival, DFS, OS and HNSCC-death were significantly worse in patients with pRND (p < 0.05) CONCLUSIONS: Incorporating FDG-PET/CT into the diagnostic pathway for the response evaluation after (chemo)radiotherapy significantly improved the accuracy of patient selection for SND and spared considerable number of patients (>20 %) from unnecessary SND. For patients with metabolic CR, SND can safely be omitted while for patients with no metabolic CR, SND is strongly advocated.

Radiation-sensitive genetic prognostic model identifies individuals at risk for radiation resistance in head and neck squamous cell carcinoma. J Cancer Res Clin Oncol 2023; 149:15623-15640. [PMID: 37656244 DOI: 10.1007/s00432-023-05304-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 08/15/2023] [Indexed: 09/02/2023]
Abstract
BACKGROUND The advantages of radiotherapy for head and neck squamous cell carcinoma (HNSCC) depend on the radiation sensitivity of the patient. Here, we established and verified radiological factor-related gene signature and built a prognostic risk model to predict whether radiotherapy would be beneficial. METHODS Data from The Cancer Genome Atlas, Gene Expression Omnibus, and RadAtlas databases were subjected to LASSO regression, univariate COX regression, and multivariate COX regression analyses to integrate genomic and clinical information from patients with HNSCC. HNSCC radiation-related prognostic genes were identified, and patients classified into high- and low-risk groups, based on risk scores. Variations in radiation sensitivity according to immunological microenvironment, functional pathways, and immunotherapy response were investigated. Finally, the expression of HNSCC radiation-related genes was verified by qRT-PCR. RESULTS We built a clinical risk prediction model comprising a 15-gene signature and used it to divide patients into two groups based on their susceptibility to radiation: radiation-sensitive and radiation-resistant. Overall survival was significantly greater in the radiation-sensitive than the radiation-resistant group. Further, our model was an independent predictor of radiotherapy response, outperforming other clinical parameters, and could be combined with tumor mutational burden, to identify the target population with good predictive value for prognosis at 1, 2, and 3 years. Additionally, the radiation-resistant group was more vulnerable to low levels of immune infiltration, which are significantly associated with DNA damage repair, hypoxia, and cell cycle regulation. Tumor Immune Dysfunction and Exclusion scores also suggested that the resistant group would respond less favorably to immunotherapy. CONCLUSIONS Our prognostic model based on a radiation-related gene signature has potential for application as a tool for risk stratification of radiation therapy for patients with HNSCC, helping to identify candidates for radiation therapy and overcome radiation resistance.

Abstract
BACKGROUND For patients with less chemosensitive neck nodes, poor prognosis after chemoradiotherapy (CRT) could be predicted and neck dissection is needed. METHODS Ninety-two N2/3 hypopharyngeal carcinoma patients were retrospectively studied. According to response after induction chemotherapy (ICT), patients were treated with neck dissection followed by concurrent CRT (CCRT) (group 1), surgery plus postoperative CRT (group 2), or CCRT for primary and regional sites (group 3). RESULTS Overall survival and disease-free survival rates of group 1 were significantly higher than group 2 (p = 0.038, p = 0.031) and group 3 (both p = 0.018). Regional control rate of group 1 was significantly higher than group 3 (p = 0.041). There were no significant differences between groups 1 and 2 regarding local and regional control (p = 0.746, p = 0.302). CONCLUSIONS Neck dissection followed by CCRT is the best choice for patients with responsive primary but nonresponsive nodes.

Post-Treatment Neck Dissection of Tonsillar and Base of Tongue Squamous Cell Carcinoma in the Era of PET-CT, HPV, and p16. Viruses 2022; 14:v14081693. [PMID: 36016315 PMCID: PMC9413897 DOI: 10.3390/v14081693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 07/27/2022] [Accepted: 07/29/2022] [Indexed: 11/25/2022] Open
Abstract
Human-papillomavirus (HPV)-positive tonsillar and base of tongue carcinomas (TSCC/BOTSCC) are rising in incidence and treatments with radiotherapy, chemoradiotherapy (RT/CRT), and neck dissections (NDs) have several side effects. Therefore, an improved selection of patients needing salvage NDs would be beneficial. We examined the prevalence and localisations of viable tumour cells in neck lymph nodes in patients post-RT/CRT, identified by fluorodeoxyglucose positron-emission tomography with computer-tomography (FDG PET-CT), with a focus on HPV-associated tumours. Patients with 217 TSCC/BOTSCC with tumours assessed for HPV-DNA and p16INK4a undergoing FDG PET-CT 12 weeks after treatment and/or an ND were included. The FDG PET-CT data were compared with the findings in the pathology report after the ND. In total, 36/217 (17%) patients were selected for an ND due to positive findings in post-treatment FDG PET-CT. Of these, 35/36 were HPV-associated, 10/36 (28%) had viable tumour cells in the pathology reports of the neck specimen, and 8/10 (80%) were consistent with the FDG PET-CT findings, while 2/36 (5%) were missed by FDG PET-CT. We conclude that FDG PET-CT 12 weeks after RT/CRT is useful, but not completely reliable for finding all the metastases of HPV-associated TSCC/BOTSCC. Nonetheless, our data indicate that an ND could be more selectively guided by FDG PET-CT.

Abstract
Mucin 1 (MUC1), a transmembrane glycoprotein, has shown to be as the possible prognostic marker to predict the risk of aggressive head and neck squamous cell carcinoma (HNSCC). In the present study, we investigated the effect of MUC1 in HNSCC cells and the response to X-ray irradiation (IR). Here, we examined the impact of MUC1 overexpression or downexpression on clonogenic survival and apoptosis in response to X-ray irradiation (IR). Radioresistance and radiosensitivity were also observed in HNSCC cells that are MUC1 overexpression and MUC1 downexpression. This enhanced resistance to IR in MUC1-overexpressing cells is primarily due to increased the number of radiation-induced γH2AX/53BP1-positive foci and DNA double-strand break (DSB) repair kinetics. MUC1 overexpression repaired more than 90% of DSBs after 2 Gy radiation by 24 h compared to the empty vector overexpressing cells with less than 50% of DSB repair. However, MUC1 downexpression repaired less than 20% of DSBs compared to the empty vector-overexpresing cells. MUC1 overexpression inhibited proapoptotic protein expression, such as caspase-3, caspase-8, and caspase-9, and induced antiapoptotic protein Bcl-2, followed by resistance to IR-induced apoptosis. Our results showed that targeting MUC1 may be as a promising strategy to counteract radiation resistance of HNSCC cells.

Abstract
BACKGROUND Computed tomography (CT) performed after radiation therapy (RT) is used to detect residual lymph node (LN) metastasis. Here, we investigated which LN parameters on pre- and post-RT CT images correlated with residual tumour in patients with head and neck cancer. PATIENTS AND METHODS We enrolled 23 patients who received RT. A total of 50 LNs were evaluated. Correlations between quantitative and qualitative findings and residual tumours were evaluated. RESULTS The median patient age was 61 years. Thirty-one LNs were histologically confirmed to contain residual tumour. LNs with residual tumour had significantly longer short and long axes on post-RT CT images. A new finding of obscured margins after RT were significantly associated with the presence of residual tumour by univariate and multivariate analyses. CONCLUSION Comparison of qualitative, LN parameters on pre- and post-RT CT images may improve the detection of residual tumour in patients with suspected residual or recurrent LN metastasis.

Abstract
BACKGROUND AND PURPOSE Human papillomavirus-associated oropharyngeal cancer (HPV+ OPC) with regional lymph node metastases has a good prognosis following (chemo)radiation therapy (C/RT) but lymph nodes may remain detectable for several months. Delayed [18F]-Fluorodeoxyglucose positron emission tomography/computed tomography (PET) can identify patients who may avoid post-treatment neck dissection (PTND). We investigated the rate of PTND in HPV+ OPC treated with C/RT and delayed PET-directed management of the neck. MATERIALS AND METHODS This is a retrospective cohort study from a prospectively updated institutional database. Eligible patients were treated between January 2005 and July 2017 with a minimum of 18 months follow up, had node-positive, non-distant metastatic HPV+ OPC and were treated with RT (70 Gy/35#/5 per week) with concurrent Cisplatin or Cetuximab, or accelerated RT alone (68 Gy/34#/6 per week). The primary endpoint was rate of PTND. Secondary endpoints were locoregional failure free survival (LRFFS), regional failure free survival (RFFS), distant metastatic failure free survival (DMFFS), overall survival (OS) and oropharyngeal cancer-specific survival (CSS). RESULTS 418 patients were eligible. Nineteen patients (4.5%) received a PTND. None of the tested variables were associated with an increased risk of PTND. Five-year probabilities for LRFFS, RFFS, DMFS, OS and CSS were, 91.2% (95% CI 88.3-94.2), 93.4% (95% CI 90.8-96.0), 91.2% (95% CI 88.3-94.2), 86.4% (95% CI 83.0-90.1) and 90.2% (95% CI 87.1-93.4), respectively. CONCLUSION In a large cohort with good median follow up and protocolized C/RT, delayed PET-directed management of the neck affords a lower rate of PTND than reported in historical series without compromising disease control and survival.

Abstract
OBJECTIVES In patients with N3 head and neck squamous cell carcinoma (HNSCC), N3 disease is associated with high regional relapse and metastatic risks. Patients with resectable N3 disease have better prognosis although their metastatic risk may be similar as in patients with unresectable disease. Neoadjuvant chemotherapy has been associated with lower metastatic rates, but N3 patients may die of rapid locoregional progression. We assessed outcomes with the three modalities in patients with low primary burden to better assess the specific prognosis of N3 disease. METHODS This retrospective multicentric study included T0-2 N3 HNSCC patients. Outcomes and morbidity in upfront neck dissection (uND) vs non-surgical groups were analysed and oncological outcomes and morbidity compared between patients undergoing chemoradiation or neoadjuvant chemotherapy in patients with initially unresectable N3 nodes. RESULTS Of 301 patients, 142 (47%) underwent uND, 68 (23%) neoadjuvant chemotherapy and 91 (30%) chemoradiation. The 24- and 60-month incidence of locoregional relapse was 23.2% [18.3%; 28.4%] and 27.4% [21.8%; 33.3%]; it was lower in patients undergoing uND (P = .006). In patients with non-surgical treatments, success rates were 57.8% [49.4%; 66.3%] after chemoradiation and 38.1% [29.6%; 46.7%] after neoadjuvant chemotherapy (P = .001). Overall morbidity was more frequent in patients undergoing uND (68.8%) (P < .001). CONCLUSION uND improved locoregional control but increased morbidity and showed no survival benefit. Success rates were better after chemoradiation versus neoadjuvant chemotherapy. Neoadjuvant chemotherapy did not reduce metastatic rates but non-responders to chemoradiation had poor PFS and survival rate, suggesting that predictive criteria are warranted.

Abstract
OBJECTIVE To systematically review the evaluation of the diagnostic accuracy of pre-treatment apparent diffusion coefficient (ADC) and change in ADC during the intra- or post-treatment period, for the prediction of locoregional failure in patients with head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS Ovid-MEDLINE and Embase databases were searched up to September 8, 2018, for studies on the use of diffusion-weighted magnetic resonance imaging for the prediction of locoregional treatment response in patients with HNSCC treated with chemoradiation or radiation therapy. Risk of bias was assessed by using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. RESULTS Twelve studies were included in the systematic review, and diagnostic accuracy assessment was performed using seven studies. High pre-treatment ADC showed inconsistent results with the tendency for locoregional failure, whereas all studies evaluating changes in ADC showed consistent results of a lower rise in ADC in patients with locoregional failure compared to those with locoregional control. The sensitivities and specificities of pre-treatment ADC and change in ADC for predicting locoregional failure were relatively high (range: 50-100% and 79-96%, 75-100% and 69-95%, respectively). Meta-analytic pooling was not performed due to the apparent heterogeneity in these values. CONCLUSION High pre-treatment ADC and low rise in early intra-treatment or post-treatment ADC with chemoradiation, could be indicators of locoregional failure in patients with HNSCC. However, as the studies are few, heterogeneous, and at high risk for bias, the sensitivity and specificity of these parameters for predicting the treatment response are yet to be determined.

Abstract
BACKGROUND The prognosis of advanced nodal (N3) squamous cell carcinoma of the head and neck (HNSCC) is poor. We investigated whether surgery or radiotherapy of early (T1-2) primary stage HSNCC is preferable to limit the overall morbidity after upfront neck dissection (uND) for N3 disease. METHODS This retrospective multicentric Groupe d'Étude des Tumeurs de la Tête Et du Cou study included patients undergoing uND and surgery or radiotherapy of their primary. Prognostic factors were evaluated using propensity score matching to account for biases in performing surgery depending on primary site and stage. RESULTS Of 189 T1-2, N3 HNSCC patients, 70 (37.0%) underwent uND: 42 with surgery of their primary and 28 with radiotherapy only. Radiotherapy alone was more frequent in patients with hypopharyngeal primaries. All local (N = 3) and regional (N = 10) relapses (included 2 locoregional relapses) occurred within the first 2 years. There were 16 distant metastatic failures. Five-year locoregional relapse and survival incidences were 15.7% and 66.5% and were similar regardless of the treatment of the primary. The overall morbidity rate was 65.2% and was similar after weighting by the inverse propensity score (p = 0.148). The only prognostic factor for morbidity was the radicality of the uND. Prolonged parenteral feeding was not more frequent in patients only irradiated to their primary (p = 0.118). Prolonged tracheostomy was more frequent after surgery of the primary. CONCLUSIONS In patients with T1-2, N3 HNSCC undergoing uND, radiotherapy and surgery of the primary yield similar oncological outcomes. Morbidity was related to the extent of neck dissection.

Abstract
BACKGROUND This study was undertaken to assess the effects of neo-adjuvant chemotherapy (NACT) on patients with head and neck squamous cell carcinoma (HNSCC) having advanced unresectable cervical nodal metastasis. METHODOLOGY A retrospective cohort study was conducted to assess the response of unresectable nodes to NACT in a pragmatic manner. Patients were grouped according to the response noted and the treatment offered after chemotherapy. The median survival amongst the patients in these groups was compared. RESULTS The study included 51 patients. Oral cavity was the commonest site (67.2%). Favourable nodal response was seen in 64.7% of the patients. Up to 87.9% of the nodal responders were amenable to curative intent therapy. The overall survival of patients undergoing surgery, definitive chemoradiotherapy, palliative chemotherapy and palliative radiotherapy was 24, 13, 10 and 9 months, respectively. CONCLUSION NACT may be utilized in HNSCC with advanced inoperable nodal disease to make them amenable to definitive therapy.

Abstract
AIMS AND OBJECTIVES Cervical lymph node metastasis in head and neck squamous cell carcinoma (HNSCC) is common. Pre-operative chemoradiotherapy (preCRT) and postoperative chemoradiotherapy (postCRT) is frequently employed in such patients. The prognostic value of viable SCC, treatment effect or no SCC in resected lymph nodes in patients who received or did not receive preCRT and postCRT was investigated. METHODS AND RESULTS Resected cervical lymph nodes from 146 patients with HNSCC were evaluated for viable SCC, treatment effect or no SCC. Immunostains for Ki67, cyclin D1, caspase 3 and H2AFX were performed on viable SCC or nucleate keratin debris. Clinical and histological data were correlated with tumour recurrence or persistence. Patients with nucleate keratin debris in lymph nodes had outcomes similar to those with diffuse treatment effect and no SCC. Viable tumour in lymph nodes was associated with worse prognosis in patients who received preCRT (P = 0.01). This relative worsening of prognosis was not observed in patients with oropharyngeal SCC or recurrent disease. Lower proliferation index in lymph node SCC was associated with preCRT and with worse outcomes (P = 0.0002). Overall, patients who received preCRT or postCRT had outcomes not significantly different from those who did not. CONCLUSION The presence of viable SCC in cervical lymph nodes has prognostic import when taken in context with the patient's history. Viable SCC in lymph nodes was significantly associated with worse outcome among patients with non-oropharyngeal SCC who received preCRT. Nucleate keratin debris should not be considered viable SCC in lymph nodes.

Abstract
BACKGROUND For patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) palliative treatment options that improve overall survival are limited. The prognosis in this group remains poor and there is an unmet need for new therapeutic options. An emerging class of therapeutics, targeting tumor-specific antigens, are antibodies bound to a cytotoxic agent, known as antibody-drug conjugates (ADCs). The aim of this study was to prioritize ADC targets in HNSCC. METHODS With a systematic search, we identified 55 different ADC targets currently targeted by registered ADCs and ADCs under clinical evaluation. For these 55 ADC targets, protein overexpression was predicted in a dataset containing 344 HNSCC mRNA expression profiles by using a method called functional genomic mRNA profiling. The ADC target with the highest predicted overexpression was validated by performing immunohistochemistry (IHC) on an independent tissue microarray containing 414 HNSCC tumors. RESULTS The predicted top 5 overexpressed ADC targets in HNSCC were: glycoprotein nmb (GPNMB), SLIT and NTRK-like family member 6, epidermal growth factor receptor, CD74 and CD44. IHC validation showed combined cytoplasmic and membranous GPNMB protein expression in 92.0% of the cases. Strong expression was seen in 65.9% of the cases. In addition, 86.5% and 67.7% of cases showed ≥5% and >25% GPNMB positive tumor cells, respectively. CONCLUSIONS This study provides a data-driven prioritization of ADCs targets that will facilitate clinicians and drug developers in deciding which ADC should be taken for further clinical evaluation in HNSCC. This might help to improve disease outcome of HNSCC patients.

Abstract
OBJECTIVES/HYPOTHESIS This study aimed to analyze the effect of human papillomavirus (HPV)-associated T1-2 node-positive oropharyngeal squamous cell carcinoma (OPSCC) on nodal response, recurrent disease, and survival in patients treated according to the Rotterdam protocol. STUDY DESIGN Retrospective cohort study. METHODS In total, 77 patients with T1-2 OPSCC with nodal disease, treated between 2000 and 2012, were included in this study. Patients were treated according to the Rotterdam protocol: 46 Gy of IMRT followed by a local boost using cyberknife or brachytherapy (22 Gy) and neck dissection. The presence of HPV was determined by p16INK4A immunostaining. Outcomes were overall survival, disease-free survival, and the extent of nodal response. Nodal stage was determined following the 7th and 8th American Joint Cancer Committee/Union for International Cancer Control classification. RESULTS Overall, 68.4% of patients had p16-positive disease, and 35.4% of all patients achieved complete nodal response (pN0) after 46 Gy of intensity-modulated radiotherapy (IMRT). Based on the 7th TNM classification, nodal response (partial or complete) was significantly associated with HPV status (P = .002). Patients with p16-positive OPSCC had an odds ratio (OR) of 4.6 to achieve complete nodal response. However, smoking interacted with this effect. Applying the 8th TNM classification, complete or partial response was associated with HPV status but was not significant (OR: 1.7, P = .138). Complete nodal response led to 100% overall survival in p16-positive OPSCC patients. CONCLUSIONS HPV-related OPSCCs are associated with complete nodal response after 46 Gy of IMRT. Patients with full regional control (pN0) after IMRT and subsequent neck dissection show a significantly better overall survival, but smoking negatively interacts with this effect.

Abstract
Purpose To update the guideline recommendations on the use of larynx-preservation strategies in the treatment of laryngeal cancer. Methods An Expert Panel updated the systematic review of the literature for the period from January 2005 to May 2017. Results The panel confirmed that the use of a larynx-preservation approach for appropriately selected patients does not compromise survival. No larynx-preservation approach offered a survival advantage compared with total laryngectomy and adjuvant therapy as indicated. Changes were supported for the use of endoscopic surgical resection in patients with limited disease (T1, T2) and for initial total laryngectomy in patients with T4a disease or with severe pretreatment laryngeal dysfunction. New recommendations for positron emission tomography imaging for the evaluation of regional nodes after treatment and best measures for evaluating voice and swallowing function were added. Recommendations Patients with T1, T2 laryngeal cancer should be treated initially with intent to preserve the larynx by using endoscopic resection or radiation therapy, with either leading to similar outcomes. For patients with locally advanced (T3, T4) disease, organ-preservation surgery, combined chemotherapy and radiation, or radiation alone offer the potential for larynx preservation without compromising overall survival. For selected patients with extensive T3 or large T4a lesions and/or poor pretreatment laryngeal function, better survival rates and quality of life may be achieved with total laryngectomy. Patients with clinically involved regional cervical nodes (N+) who have a complete clinical and radiologic imaging response after chemoradiation do not require elective neck dissection. All patients should undergo a pretreatment baseline assessment of voice and swallowing function and receive counseling with regard to the potential impact of treatment options on voice, swallowing, and quality of life.

Abstract
The epidermal growth factor receptor (EGFR) is one of the most comprehensively studied molecular targets in head and neck squamous cell carcinoma (HNSCC). However, inherent and acquired resistance are serious problems and are responsible for limited clinical efficacy and tumor recurrence. In this study, we evaluated the feasibility of immuno-positron emission tomography (PET) imaging and radioimmunotherapy (RIT) with 64Cu-/177Lu-PCTA-cetuximab in cetuximab-resistant SNU-1066 HNSCC xenografted model. The cellular uptake of 64Cu/177Lu-3,6,9,15-tetraazabicyclo[9.3.1]-pentadeca-1(15),11,13-triene-3,6,9,-triacetic acid (PCTA)-cetuximab showed good correlation with western blot and flow cytometry analysis in EGFR expression level of various HNSCC cells. 177Lu-PCTA-cetuximab selectively killed cetuximab-resistant SNU-1066 cells in vitro. 64Cu-/177Lu-PCTA-cetuximab specifically accumulated in SNU-1066 tumor and those uptakes were peaked at 48 h and 7 day, respectively in biodistribution, PET and single-photon emission computed tomography/computed tomography (SPECT/CT) imaging. RIT with single dose of 177Lu-PCTA-cetuximab exhibited significant tumor regression and markedly reduced 2-[18F]fluoro-2-deoxy-D-glucose (18F-FDG) uptake, compared to other groups. Proliferation index were dramatically decreased and apoptotic index increased in RIT group. These results suggest that a diagnostic and therapeutic convergence radiopharmaceutical, 64Cu-/177Lu-PCTA-cetuximab has the potential of target selection using immuno-PET imaging and targeted therapy by RIT in EGFR expressing cetuximab-resistant HNSCC tumors.

Abstract
Objective The aim of this study is to evaluate the diagnostic performance of FDG-PET/CT for the detection of residual disease after (chemo)radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC) and to evaluate the prognostic value of the FDG-PET/CT findings. Methods Patients with HNSCC who underwent FDG-PET/CT after (chemo)radiotherapy were studied retrospectively. Results 104 FDG-PET/CT-scans were performed at a median of 13.2 weeks post-treatment (5.4–19.0 weeks). The diagnostic performance was time dependent with decreasing sensitivity and slightly increasing specificity over time. Sensitivity, specificity, PPV and NPV at 9 months after imaging were 91%, 87%, 77% and 95%, respectively. In a logistic regression model, the odds of a correct FDG-PET/CT increased with 33% every additional week after end of therapy (p = 0.01) and accuracy plateaued after 11 weeks (97%; p<0.001). A complete response on FDG-PET/CT was associated with an overall survival benefit (50.7 versus 10.3 months; p<0.001). Residual disease on FDG-PET/CT increased the risk of death 8-fold (p<0.001). Conclusion FDG-PET/CT is able to detect residual disease after (chemo)radiotherapy, with an optimal time point for scanning between 11–12 weeks after therapy. However, a reevaluation is probably necessary 10–12 months after the FDG-PET/CT to detect late recurrences. In addition, FDG-PET/CT can guide decisions about neck dissection and identifies patients with poor prognosis.

PET-NECK: a multicentre randomised Phase III non-inferiority trial comparing a positron emission tomography-computerised tomography-guided watch-and-wait policy with planned neck dissection in the management of locally advanced (N2/N3) nodal metastases in patients with squamous cell head and neck cancer. Health Technol Assess 2017; 21:1-122.

Abstract
BACKGROUND Planned neck dissection (ND) after radical chemoradiotherapy (CRT) for locally advanced nodal metastases in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Thirty per cent of ND specimens show histological evidence of tumour. Consequently, a significant proportion of clinicians still practise planned ND. Fludeoxyglucose positron emission tomography (PET)-computerised tomography (CT) scanning demonstrated high negative predictive values for persistent nodal disease, providing a possible alternative paradigm to ND. Evidence is sparse and drawn mainly from retrospective single-institution studies, illustrating the need for a prospective randomised controlled trial. OBJECTIVES To determine the efficacy and cost-effectiveness of PET-CT-guided surveillance, compared with planned ND, in a multicentre, prospective, randomised setting. DESIGN A pragmatic randomised non-inferiority trial comparing PET-CT-guided watch-and-wait policy with the current planned ND policy in HNSCC patients with locally advanced nodal metastases and treated with radical CRT. Patients were randomised in a 1 : 1 ratio. Primary outcomes were overall survival (OS) and cost-effectiveness [incremental cost per incremental quality-adjusted life-year (QALY)]. Cost-effectiveness was assessed over the trial period using individual patient data, and over a lifetime horizon using a decision-analytic model. Secondary outcomes were recurrence in the neck, complication rates and quality of life. The recruitment of 560 patients was planned to detect non-inferior OS in the intervention arm with a 90% power and a type I error of 5%, with non-inferiority defined as having a hazard ratio (HR) of no higher than 1.50. An intention-to-treat analysis was performed by Cox's proportional hazards model. SETTINGS Thirty-seven head and neck cancer-treating centres (43 NHS hospitals) throughout the UK. PARTICIPANTS Patients with locally advanced nodal metastases of oropharynx, hypopharynx, larynx, oral or occult HNSCC receiving CRT and fit for ND were recruited. INTERVENTION Patients randomised to planned ND before or after CRT (control), or CRT followed by fludeoxyglucose PET-CT 10-12 weeks post CRT with ND only if PET-CT showed incomplete or equivocal response of nodal disease (intervention). Balanced by centre, planned ND timing, CRT schedule, disease site and the tumour, node, metastasis stage. RESULTS In total, 564 patients were recruited (ND arm, n = 282; and surveillance arm, n = 282; 17% N2a, 61% N2b, 18% N2c and 3% N3). Eighty-four per cent had oropharyngeal cancer. Seventy-five per cent of tested cases were p16 positive. The median time to follow-up was 36 months. The HR for OS was 0.92 [95% confidence interval (CI) 0.65 to 1.32], indicating non-inferiority. The upper limit of the non-inferiority HR margin of 1.50, which was informed by patient advisors to the project, lies at the 99.6 percentile of this estimate (p = 0.004). There were no differences in this result by p16 status. There were 54 NDs performed in the surveillance arm, with 22 surgical complications, and 221 NDs in the ND arm, with 85 complications. Quality-of-life scores were slightly better in the surveillance arm. Compared with planned ND, PET-CT surveillance produced an incremental net health benefit of 0.16 QALYs (95% CI 0.03 to 0.28 QALYs) over the trial period and 0.21 QALYs (95% CI -0.41 to 0.85 QALYs) over the modelled lifetime horizon. LIMITATIONS Pragmatic randomised controlled trial with a 36-month median follow-up. CONCLUSIONS PET-CT-guided active surveillance showed similar survival outcomes to ND but resulted in considerably fewer NDs, fewer complications and lower costs, supporting its use in routine practice. FUTURE WORK PET-CT surveillance is cost-effective in the short term, and long-term cost-effectiveness could be addressed in future work. TRIAL REGISTRATION Current Controlled Trials ISRCTN13735240.

Abstract
PURPOSE: This study evaluated the strategy of performing neck dissection (ND) without primary tumor resection prior to definitive chemoradiotherapy (CRT) for N2+ oropharynx cancer. METHODS: We analyzed records of 25 patients who underwent ND before concurrent CRT with weekly low-dose concurrent paclitaxel and a platinum compound. The extent of ND was highly customized (1 to 39 nodes) and median radiotherapy dose was 70 Gy. RESULTS: Median follow-up was 36 months. Two-year and 3-year actuarial locoregional control rates were 95% and 88%. No patient had regional neck nodal failure. Two-year rate of freedom from distant metastases was 91%. The 2- and 3-year event-free survival rates were 88% and 75%. Fifteen percent had Grade 3+ late toxicity; none had permanent gastrostomy tube dependence. CONCLUSIONS: Neck dissection without primary tumor resection before definitive chemoradiotherapy for oropharynx cancer is a safe and effective management program and warrants further exploration.

Imaging strategy for response evaluation to chemoradiotherapy of the nodal disease in patients with head and neck squamous cell carcinoma. Int J Clin Oncol 2015; 21:658-667. [PMID: 26710795 DOI: 10.1007/s10147-015-0936-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2015] [Accepted: 11/28/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND Definitive chemoradiotherapy (CRT) is used to treat lymph node metastatic head and neck cancer patients. Regional control of the neck disease is important to improve the prognosis, and the accuracy of the method used to evaluate the metastatic lymph node(s) after CRT is crucial to the decision-making process for any following salvage surgery. METHODS Patients undergoing CRT were divided in two groups of patients of those showing complete clinical response (CR) and those showing clinical non-response (non-CR), as assessed by computed tomography (CT) and/or magnetic resonance imaging (MRI), ultrasonography, fluorodeoxyglucose-positron emission tomography (FDG-PET), and fine needle aspiration cytology. The responses (CR vs. non-CR) were compared with the actual clinical outcomes. For the interim analysis, the study period was broken down into two periods, namely, the exploratory phase (patients treated between January 2002 and April 2012) and the validating phase (patients treated between May 2012 and January 2014). RESULTS The sensitivity, specificity, and accuracy were as follows: CT and/or MRI, 66.7, 73.8, and 72.8 %, respectively, in the exploratory phase; ultrasonography, 91.7, 70.6, and 73.4 %, respectively, in the exploratory phase and 80.0, 82.8, and 82.4 %, respectively, in the validating phase; FDG-PET, 50.0, 97.5, and 91.3 %, respectively, in the exploratory phase and 60.0, 100, and 94.1 %, respectively, in the validating phase; cytology, 68.4, 95.9, and 90.3 %, respectively, in the exploratory phase and 66.7, 100, and 85.7 %, respectively, in the validating phase. CONCLUSIONS Based on our results, CT and/or MRI appear to be inadequate methods for the evaluation of the response of lymph node(s) to CRT. In contrast, ultrasonography appears to be a highly sensitive and useful tool for positive screening at 6-8 weeks after CRT, and FDG-PET appears to be a highly specific and useful tool for negative screening at 8-12 weeks after CRT.

Abstract
ORIGINAL STATEMENT Lymph node metastases in the neck are a major prognostic factor in patients with head and neck squamous cell carcinoma (HNSCC). Assessment and treatment of lymph nodes in the neck are of utmost importance. Inappropriate management of lymph node metastases can result in regional failure. Radical neck dissection has been and is still considered the "gold standard" for the surgical management of lymph node metastases of HNSCC. However, the philosophy of treatment of the neck has evolved during the last decades. Surgeons progressively realized that extensive neck dissections were associated with a higher morbidity but not always with a better oncologic outcome than more limited procedures. Today, a comprehensive therapeutic approach of the neck is multidisciplinary, taking into account the patient's quality of life without jeopardizing cure and survival. A better understanding of the patterns of lymph node metastasis promoted the use of selective neck dissection in selected patients. Sentinel lymph node biopsy is a reliable diagnostic procedure for staging the neck in node-negative early oral cavity squamous cell carcinoma. With increasing use of chemoradiation in locally advanced HNSCC, paradigms are evolving. Currently, there are strong arguments supporting the position that neck dissection is no longer justified in patients without clinically residual disease in the neck.

Abstract
BACKGROUND The goal of the current study was to assess the rates of recurrence in the neck for patients with lymph node-positive human papillomavirus-associated cancer of the oropharynx who were treated with definitive radiotherapy (with or without chemotherapy). METHODS This is a single-institution retrospective study. Methodology included database search, and statistical testing including frequency analysis, Kaplan-Meier tests, and comparative tests including chi-square, logistic regression, and log-rank. RESULTS The cohort consisted of 401 patients with lymph node-positive disease who underwent radiotherapy between January 2006 and June 2012. A total of 388 patients had computed tomography restaging, and 251 had positron emission tomography and/or ultrasound as a component of their postradiation staging. Eighty patients (20%) underwent neck dissection, and 21 patients (26%) had a positive specimen. The rate of neck dissection increased with increasing lymph node stage, and was lower in patients who had positron emission tomography scans or ultrasound in addition to computed tomography restaging. The median follow-up was 30 months. The 2-year actuarial neck recurrence rate was 7% and 5%, respectively, in all patients and those with local control. Lymph node recurrence rates were greater in current smokers (P = .008). There was no difference in lymph node recurrence rates noted between patients who did and those who did not undergo a neck dissection (P = .4) CONCLUSIONS: A treatment strategy of (chemo)radiation with neck dissection performed based on response resulted in high rates of regional disease control in patients with human papillomavirus-associated oropharyngeal cancer.

Abstract
CONCLUSION Neck dissection (ND) may not be warranted for those patients with complete response in the neck. Human papillomavirus (HPV)-positive or -negative tumour does not affect this recommendation. OBJECTIVES Treatment of tonsillar cancer varies considerably worldwide, although non-surgical treatment, e.g. radiotherapy (RT), possibly combined with chemotherapy (CRT), is gradually coming to be regarded as the first line of therapy. However, the optimal treatment of nodal disease remains controversial, and the fundamental question is if and when to perform ND. METHODS We performed a retrospective analysis of all patients with tonsillar cancer treated in the Stockholm area between 2000 and 2006. An analysis of node-positive tumours was done and the neck specimen was investigated for the presence of viable tumour cells after RT. A sub-analysis of HPV status was also carried out. RESULTS Following complete response after RT, 2% of patients showed viable cells in the neck specimen, compared with 60% in patients who did not show complete response. HPV-positive tumours had the same proportion of viable tumour cells in the neck specimen as HPV-negative tumours.

Abstract
BACKGROUND Concurrent chemoradiotherapy (CCRT) is used to treat advanced head and neck cancer. The accuracy of evaluating lymph nodes metastases following CCRT is important for subsequent therapy. PATIENTS AND METHODS Patients were divided into two groups according to the nodal status, the complete response (CR) and the non-CR groups, as determined by imaging and fine-needle aspiration cytology (FNAC) performed 4-8 weeks after the CCRT, and the findings were compared with the status 6 months after the treatment completion. RESULTS The sensitivity, the specificity, positive predictive value, negative predictive value and accuracy of each evaluation method were as follows: 66.7%, 73.5%, 26.7%, 93.8% and 72.5%, respectively, for computer tomography (CT) and magnetic resonance imaging (MRI); 91.7%, 69.9%, 30.6%, 98.3% and 72.6% for ultrasonography (US) ; 50.0%, 96.4%, 66.7%, 93.0% and 90.5% for fluorodeoxyglucose-positron emission tomography (FDG-PET) or PET-CT; and 68.4%, 96.1%, 81.3%, 92.5% and 90.6% for FNAC. CONCLUSION To evaluate the response of lymph node(s) treated by CCRT, US is useful as a positive screening tool and FDG-PET and PET-CT as negative screening tools. FNAC is useful in evaluating suspicious lymph nodes in both positive and negative cases.

Abstract
The aim of this study was to investigate human papillomavirus (HPV) infection as a predictor of concurrent chemoradiotherapy (CCRT) response and indicator of planned neck dissection (PND) for patients with advanced oropharyngeal squamous cell carcinoma (OPSCC; stage III/IV). Overall, 39 OPSCC patients (32 men, 7 women; median age 61 years, range 39–79 years) were enrolled. The primary lesion and whole neck were irradiated up to 50.4 Gy, and subsequently the primary site and metastatic lymph nodes were boosted with a further 16.2 Gy. Although several chemotherapy regimens were employed, 82.1% of OPSCC patients received the combination of nedaplatin and 5-fluorouracil. HPV-related OPSCC (16 cases) was defined as both HPV DNA-positive status by polymerase chain reaction and p16INK4a overexpression by immunohistochemistry. Patients with N2 and N3 disease received PND 2–3 months after CCRT completion. Compared to non-responders, CCRT responders showed significantly lower nodal stage (N0 to N2b) and HPV-positive status in univariate analysis. Patients with HPV-related OPSCC had longer time to treatment failure (TTF) than those with HPV-unrelated OPSCC (p=0.040). Three-year TTF was 81.3 and 47.8% in the HPV-related and HPV-unrelated groups, respectively. There were also significant differences in disease-free survival (DFS) between the two OPSCC patient groups (p=0.042). Three-year DFS was 93.8 and 66.7% in patients with HPV-related and HPV-unrelated OPSCC, respectively. Multivariate logistic analysis showed a lower risk of TTF event occurrence in HPV-related OPSCC (p=0.041) than in HPV-unrelated OPSCC. Thus, HPV testing in addition to nodal stage was useful for predicting CCRT response, especially in advanced OPSCC. Because patients who received PND showed moderate locoregional control, PND is an effective surgical procedure for controlling neck lesions in patients with advanced HPV-unrelated disease.

Abstract
Squamous cell carcinoma of the head and neck (SCCHN) is the sixth most common cancer worldwide. The main risk factors for cancers of the oral cavity, larynx, oropharynx, and hypopharynx are alcohol and tobacco use. In addition, the human papillomavirus (HPV) is an established cause of oropharyngeal cancer. An experienced multidisciplinary team is necessary for adequate management and optimal outcome. The treatment of locally advanced disease generally requires various combinations of radiotherapy, surgery, and systemic therapy, but despite this aggressive multimodal treatment, 40% to 60% of the patients will relapse. In this report, we will discuss recent advances in the management of SCCHN, including new developments in molecular biology, imaging, and treatment.

Abstract
OBJECTIVE The objective of this study was to compare the efficacy of surveillance high-resolution computed tomography (HRCT) and physical examination/endoscopy (PE/E) with the efficacy of fluorodeoxyglucose (FDG)-positron emission tomography (PET)/HRCT for the detection of relapse in head and neck squamous cell carcinoma (HNSCC) after primary treatment. METHODS This is a retrospective analysis of contemporaneously performed FDG-PET/HRCT, neck HRCT, and PE/E in 99 curatively treated patients with HNSCC during post-therapy surveillance to compare performance test characteristics in the detection of early recurrence or second primary cancer. RESULTS Relapse occurred in 19 of 99 patients (20%) during a median follow-up of 21 months (range: 9-52 months). Median time to first PET/HRCT was 3.5 months. The median time to radiological recurrence was 6 months (range: 2.3-32 months). FDG-PET/HRCT detected more disease recurrences or second primary cancers and did so earlier than HRCT or PE/E. The sensitivity, specificity, and positive and negative predictive values for detecting locoregional and distant recurrence or second primary cancer were 100%, 87.3%, 56.5%, and 100%, respectively, for PET/HRCT versus 61.5%, 94.9%, 66.7%, and 93.8%, respectively, for HRCT versus 23.1%, 98.7%, 75%, and 88.6%, respectively, for PE/E. In 19 patients with true positive PET/HRCT findings, a significant change in the management of disease occurred, prompting either salvage or systemic therapy. Of the 14 curatively treated patients, 11 were alive with without disease at a median follow-up of 31.5 months. CONCLUSION FDG-PET/HRCT has a high sensitivity in the early detection of relapse or second primary cancer in patients with HNSCC, with significant management implications. Given improvements in therapy and changes in HNSCC biology, appropriate modifications in current post-therapy surveillance may be required to determine effective salvage or definitive therapies.

Abstract
There has been a long lasting debate, whether planned neck dissections after curative radio(chemo)therapy for locally advanced head and neck squamous cell carcinomas offer some benefit in tumor control or survival. We did a thorough literature research on that topic. The results of several recently published studies are described, summarized, and reviewed. Patients with residual disease in clinical or radiographic examinations (CT or MRI scans) up to 3 months after completion of radiochemotherapy profit from neck dissections. In patients with an initial or delayed clinical complete remission after completion of radiochemotherapy, a neck dissection can be safely omitted. In conclusion, there is no longer evidence for a benefit of prophylactic post-radiochemotherapy neck dissections, but strong evidence for a therapeutic post-radiochemotherapy neck dissection in this group of patients.

Abstract
Until a few decades ago neck dissection (ND) was the standard surgical approach for node-positive tumours. Nowadays patients with locally advanced head and neck cancer can be treated with definitive chemoradiation (CRT), which includes the treatment of the neck; however, results on residual viable tumour after conservative treatment are heterogeneous and depend on initial node stage and primary treatment. Many authors accept adjuvant surgery in patients with N2-3 disease. Regardless of the results of upfront CRT, even if there is no evidence of lymph node metastases, when the risk for persistent positive neck nodes exceeds 15-20%, elective ND might be indicated. However, despite the diffusion of innovative technologies and therapies, there are controversies about both response evaluation and surgical management of initially involved neck nodes after definitive CRT and organ preservation treatment. In this paper we will analyse state of art of neck evaluation after CRT and discuss the role of ND.

Abstract
Introduction. Optimal therapy for patients with metastatic neck disease remains controversial. Neck dissection following radiotherapy has traditionally been used to improve locoregional control. Methods. A retrospective review of 28 patients with node-positive head and neck malignancy treated with planned neck dissection following radiotherapy between January 2002 and December 2005 was performed to assess treatment outcomes. Results. Median interval to neck dissection was 9.6 weeks with a median number of 21 + 9 lymph nodes per specimen. Ten of 31 (32%) neck dissection specimens demonstrated evidence of residual carcinoma. Overall survival at two years was 85%; five-year overall survival was 65%. Concurrent chemotherapy did not impact the presence of residual neck disease. Conclusion. Based on the frequency of residual malignancy in the neck of patients treated with primary radiotherapy, a planned, postradiotherapy neck dissection should be strongly advocated for all patients with advanced-stage neck disease.

Abstract
BACKGROUND To investigate the impact of up-front neck dissection on the outcome of patients with node-positive hypopharyngeal cancer (HPC) treated with (chemo)radiation. METHODS Of 135 consecutive patients with node-positive HPC, 32 patients underwent up-front neck dissection followed by (chemo)radiation (group 1), and 103 patients received definitive (chemo)radiation (group 2). RESULTS The 3-year regional, local and distant control for groups 1 and 2 were 92% versus 87% (p = .37), 84% versus 72% (p = .15), and 80% versus 62% (p = .08), respectively. High T classification was the only significant predictor for poor overall survival on multivariate analysis (OR = 3.0, p = .02). Acute and late toxicities and the prospectively assessed quality of life were comparable in both groups. CONCLUSION Upfront neck dissection followed by (chemo)radiation did not negatively impact on oncologic outcomes, toxicity, or quality of life and therefore is to be regarded as a safe and effective treatment option for small HPC with bulky nodal disease, especially in busy radiation departments with unacceptably long waiting time for definitive (chemo)radiation.

Abstract
BACKGROUND The aim of the present study was to assess, in the setting of a single-institution prospective clinical trial, the necessity of planned neck dissection (PND) in physically and radiologically complete responders with pretherapy advanced nodal disease. METHODS Between January 2000 and July 2007 a total of 139 patients were enrolled to receive a regimen of platinum-based multidrug induction-concurrent chemoradiotherapy (IC/CCRT). A total of 75 of the enrolled patients with advanced nodal disease were included in this retrospective study. Between 8 and 12 weeks from the end of treatment, the response to IC/CCRT was evaluated by fiber-optic endoscopy and head and neck contrast-enhanced computed tomography or magnetic resonance imaging. RESULTS The complete clinical response (cCR) rate was 68%. Among the 51 patients who achieved locoregional cCR at the end of CCRT, 8 underwent PND according to the study recommendation. Of the 43 patients with cCR who did not undergo PND, 2 patients (4.7%) experienced isolated regional recurrences with the 5-year regional control being 82%. Patients with cCR did not have a significantly lower regional control compared with patients with cCR who underwent ND (P=.962). Pathological evidence of residual disease was found in 81% of the patients with less than cCR who underwent ND. CONCLUSIONS In physically and radiologically complete responders to IC/CCRT, a PND appears not justified. Conversely, PND should be performed in patients clinically suspected of having residual disease in the neck, as a significant proportion have viable tumor cell in post CCRT ND.

Abstract
BACKGROUND The purpose of this study was to evaluate the prognostic impact of the sixth edition of the Union Internationale Contre le Cancer (UICC) classification and different TNM-based stage groupings for malignant tumors of the ethmoid sinuses and the nasal cavity. METHODS We conducted a retrospective analysis of 98 patients with malignant tumors of the ethmoid sinuses and the nasal cavity between 1967 and 2003. The UICC classification of the sixth edition and the T and N Integer Score (TANIS) and Hart were tested for their prognostic significance. RESULTS In univariate analysis, all stage groupings revealed discriminatory power for overall survival (OS; p < .05), however, in multivariate analysis only the UICC-stage grouping (p = .033) and the TANIS-8 scheme (p = .044) predicted OS. The TANIS did not have a better prognostic quality than the sixth edition of the UICC classification. CONCLUSION The UICC-stage grouping of the sixth edition is a good prognostic index for malignant tumors of the ethmoid sinuses and the nasal cavity.

[PMID: 22137026 DOI: 10.1016/j.ijrobp.2011.07.042] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2011] [Revised: 07/13/2011] [Accepted: 07/29/2011] [Indexed: 10/14/2022]
Abstract
PURPOSE To assess the role of a planned neck dissection (PND) after sequential chemoradiotherapy for patients with head-and-neck cancer with N2-N3 nodal disease. METHODS AND MATERIALS We reviewed 90 patients with N2-N3 head-and-neck squamous cell carcinoma treated between 1991 and 2001 on two sequential chemoradiotherapy protocols. All patients received induction and concurrent chemotherapy with cisplatin and 5-fluorocuracil, with or without tirapazamine. Patients with less than a clinical complete response (cCR) in the neck proceeded to a PND after chemoradiation. The primary endpoint was nodal response. Clinical outcomes and patterns of failure were analyzed. RESULTS The median follow-up durations for living and all patients were 8.3 years (range, 1.5-16.3 year) and 5.4 years (range, 0.6-16.3 years), respectively. Of the 48 patients with nodal cCR whose necks were observed, 5 patients had neck failures as a component of their recurrence [neck and primary (n = 2); neck, primary, and distant (n = 1); neck only (n = 1); neck and distant (n = 1)]. Therefore, PND may have benefited only 2 patients (4%) [neck only failure (n = 1); neck and distant failure (n = 1)]. The pathologic complete response (pCR) rate for those with a clinical partial response (cPR) undergoing PND (n = 30) was 53%. The 5-year neck control rates after cCR, cPR→pCR, and cPR→pPR were 90%, 93%, and 78%, respectively (p = 0.36). The 5-year disease-free survival rates for the cCR, cPR→pCR, and cPR→pPR groups were 53%, 75%, and 42%, respectively (p = 0.04). CONCLUSION In our series, patients with N2-N3 neck disease achieving a cCR in the neck, PND would have benefited only 4% and, therefore, is not recommended. Patients with a cPR should be treated with PND. Residual tumor in the PND specimens was associated with poor outcomes; therefore, aggressive therapy is recommended. Studies using novel imaging modalities are needed to better assess treatment response.

Abstract
OBJECTIVE Determine prevalence of viable malignancy in patients undergoing neck dissection (ND) for residual neck disease following concomitant chemotherapy and irradiation (chemo/xrt) for upper aerodigestive squamous carcinoma. To determine survival in groups with a neck complete response to those who had residual disease requiring neck dissection. STUDY DESIGN Retrospective chart review. METHODS Retrospective chart review of 230 patients who underwent definitive chemo/xrt for primary squamous cell carcinoma cancer (SCCa) of the head and neck from 2005 to 2009 in one institution. RESULTS Thirty-nine (17%) patients underwent ND for residual neck mass within 4 months posttreatment. Forty-nine percent (19/39) were pathologically positive for malignancy and 51% (20/39) were negative. The probability of a +ND based on original N-stage was not statistically significant (P = .368). Primary site did not yield significant probability of having +ND, except in the oral cavity (P = .02). Patients had similar overall 5-year survival, among those with a delayed complete response in the neck (66%), ND for residual disease (71%), or those with initial complete response (71%). Lower initial N-stage demonstrated improved survival in all outcome groups. Tonsil SCCa patients who underwent ND had improved survival compared to those with delayed complete response (87.5 vs. 75.8%), both of which had increased survival compared to initial complete responders (65%). CONCLUSIONS This study supports the use of ND in the postchemo/xrt positive neck regardless of primary site or initial N-stage. ND in this setting conveys survival equal to patients with complete response in the neck after chemo/xrt. These survivorship implications of postchemo/xrt neck dissection extend to all sites, including tonsils.

Abstract
AIMS This study assessed neck control in patients with N2 head and neck squamous cell carcinoma (HNSCC) treated with sequential chemoradiotherapy (SCRT) and the incidence of neck recurrence when neck dissection was withheld in those with negative post-treatment fluorine-18 fluorodeoxyglucose positron emission tomography (FDG PET). MATERIALS AND METHODS Thirty-four consecutive patients with N2 HNSCC who were treated with radical intent using SCRT were included. Twenty-seven patients received concomitant platinum-based chemotherapy with their radiotherapy. Nineteen patients were treated with intensity-modulated radiotherapy. PET-computed tomography (PET-CT) was obtained 3 months after the completion of radical radiotherapy. Neck dissection was carried out only in those with increased FDG uptake in the neck. RESULTS The median follow-up was 39.1 months. One patient had increased FDG uptake in the neck post-treatment, which was false positive for malignancy. The remaining 33 patients were observed without neck dissection. No regional recurrence occurred. The negative predictive value (NPV) of post-treatment PET-CT was 100%. CONCLUSIONS Good disease control in the neck can be achieved in patients with N2 HNSCC with SCRT. Post-treatment PET-CT has a high NPV. Neck dissection can be avoided if post-treatment PET-CT is negative.

Abstract
BACKGROUND The objective of this study was to determine the prognostic significance of viable tumor in postchemoradiation neck dissection specimens in patients with squamous cell carcinoma of the laryngopharynx. METHODS Retrospective analysis identified 181 patients treated with primary concurrent chemoradiation for carcinoma of the laryngopharynx at Memorial Sloan-Kettering Cancer Center between the years 1995 and 2005. Of these, 56 patients had a comprehensive neck dissection either as a planned or salvage procedure. Neck dissection specimens were analyzed by a single pathologist for the presence of viable tumor. The presence of viable tumor was correlated to the timing of neck dissection after chemoradiation and to tumor response. Overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) were determined by the Kaplan-Meier method, and correlation to tumor viability was determined with the log-rank test. RESULTS Nineteen (33%) patients had viable tumor in their neck dissection specimens. Viable tumor was higher in patients who had a less-than-complete response to chemoradiation compared with those who had a complete response (42% vs 25%, p = .1). There was no correlation to timing of neck dissection. The 5-year OS, DSS, and RFS were significantly lower in patients who had viable tumor in their neck dissection specimens (OS 49% vs 93%, p = .0005; DSS 56% versus 93%, p = .003; RFS 40% vs 75%, p = .004). CONCLUSIONS Patients with viable tumor in postchemoradiation neck dissection specimens had a poorer outcome compared with patients with no viable tumor.

Abstract
OBJECTIVE To determine whether computed tomography can distinguish low risk neck levels that can be omitted when neck dissection is undertaken after chemoradiotherapy. STUDY DESIGN Case series with chart review. SETTING Tertiary care center. SUBJECTS AND METHODS Head and neck squamous cell carcinoma patients undergoing neck dissection after chemoradiotherapy between January 1998 and June 2008. We compared computed tomography findings after chemoradiotherapy with neck dissection pathology results; used primary location and computed tomography findings to design selective or superselective neck dissection; and determined whether these surgeries would have contained all metastatic disease. RESULTS A total of 104 patients were identified, providing 110 heminecks, 531 neck levels, and 3009 lymph nodes for analysis. Neck dissections were positive in 20 (19%) of 104 patients, corresponding to 20 hemineck dissections, 31 neck levels, and 53 lymph nodes. The negative predictive value for computed tomography was 95 percent. The negative predictive value for computed tomography per neck level was as follows: I, 100 percent; II, 96 percent; III, 96 percent; IV, 97 percent; and V, 96 percent. A selective neck dissection or a superselective neck dissection, guided by level specific computed tomography findings and limited to necks with post treatment partial response in one level, would have captured all disease in 52 (95%) of 55 and 51 (93%) of 55 heminecks. CONCLUSION Negative computed tomography accurately predicts pathologic complete response at neck dissection. Neck dissection can be avoided in these patients. Additionally, computed tomography reliably identifies low risk neck levels that do not require dissection, permitting selective neck dissection or superselective neck dissection in partial response patients with limited residual disease.

Abstract
For patients with advanced regional disease, neck dissection following (chemo)radiotherapy remains controversial. Selective neck dissection (SND) was reported as suitable after chemoradiation in patients with advanced regional disease. Reduced morbidity represents the major advantage of SND. In a situation in which there is a major fibrosis around the previously invaded nodes, resection of 1 or more nonlymphatic structures may be required. The current classification of SND could be implemented by the addition of extended selective neck dissection (ESND). The standard basic procedures for SND spare the sternocleidomastoid muscle (SCM), the internal jugular vein (IJV), and the spinal accessory nerve (SAN). When an SND is associated with the resection of 1 or more nonlymphatic structures, it should be termed ESND. All additional nonlymphatic structure(s) removed should be identified in parentheses. The proposal to subclassify SND not only in accord with the resected lymph node levels but also upon the nonlymphatic structures removed may be of some help to avoid potential misinterpretation.

Abstract
BACKGROUND In locally advanced head and neck cancer, concurrent chemoradiotherapy (CRT) with combined 5-fluorouracil (5-FU) and cisplatin has increased acute toxicities as well as survival. Once-weekly chemotherapeutic administration schedule may reduce severe toxicities. Thus, we investigated CRT using weekly administration of 5-FU-cisplatin in locally advanced head and neck cancer. METHODS In a single-arm, phase II study, CRT included radiation (70.0 Gy/35 fr) and weekly 5-FU (750 mg/m2) and cisplatin (20 mg/m2). RESULTS Thirty-two patients completed planned radiation. Thirteen (41%) achieved complete response, and 16 (50%) partial response. Twelve patients (38%) experienced acute grade 3 toxicities. Grade 3 mucositis, which was the most common toxicity, developed in 5 (16%) patients. The survival rates at 1 and 2 years were 81% and 76%, respectively. The progression-free survival rates at 1 and 2 years were 69% and 66%, respectively. CONCLUSIONS We demonstrated weekly 5-FU-cisplatin with conventional radiotherapy was efficacious and feasible with high compliance rate in locally advanced head and neck cancer.

Abstract
The question of efficacy of "planned" neck dissection following complete response to chemoradiation of head and neck cancer is discussed. There is general agreement that preemptive neck dissection in patients who present initially with low volume (N1) neck disease is not necessary. However, routine performance of planned neck dissection for patients who present initially with high volume (> or =N2) disease remains controversial. The authors reviewed a large number of studies reported in the recent literature and discuss how they affect this debate.Twenty-four of the reviewed studies indicate a benefit in regional control obtained by "planned" neck dissection among patients who had bulky neck disease pretreatment. All these studies are retrospective, they do not assess treatment response prior to surgery, although they do show very good regional control rates. Twenty-six studies demonstrate no benefit from "planned" neck dissection after complete clinical response. The reasons for these different conclusions include the development of more effective chemoradiation regimens which have improved the initial locoregional control rates of patients undergoing primary chemoradiation treatment, and improvements in diagnostic technology which have increased ability to detect low volume persistent tumor in the post treatment period. When neck dissection is necessary for persistent or recurrent disease, recent studies have shown that selective or superselective neck dissection may produce results therapeutically equivalent to those obtained with more extensive procedures, with less morbidity.There is now a large body of evidence, based on long-term clinical outcomes, that patients who have achieved a complete clinical (including radiologic) response to chemoradiation have a low rate of isolated neck failure, and the continued use of planned neck dissection for these patients cannot be justified.

Abstract
PURPOSE To show the relationship between antibody delivery and therapeutic efficacy in head and neck cancers, in this study we evaluated the pharmacokinetics and pharmacodynamics of epidermal growth factor receptor (EGFR)-targeted immunotherapy and radioimmunotherapy by quantitative positron emission tomography (PET) imaging. EXPERIMENTAL DESIGN EGFR expression on UM-SCC-22B and SCC1 human head and neck squamous cell cancer (HNSCC) cells were determined by flow cytometry and immunostaining. Tumor delivery and distribution of cetuximab in tumor-bearing nude mice were evaluated with small animal PET using (64)Cu-DOTA-cetuximab. The in vitro toxicity of cetuximab to HNSCC cells was evaluated by MTT assay. The tumor-bearing mice were then treated with four doses of cetuximab at 10 mg/kg per dose, and tumor growth was evaluated by caliper measurement. FDG PET was done after the third dose of antibody administration to evaluate tumor response. Apoptosis and tumor cell proliferation after cetuximab treatment were analyzed by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling and Ki-67 staining. Radioimmunotherapy was done with (90)Y-DOTA-cetuximab. RESULTS EGFR expression on UM-SCC-22B cells is lower than that on SCC1 cells. However, the UM-SCC-22B tumors showed much higher (64)Cu-DOTA-cetuximab accumulation than the SCC1 tumors. Cetuximab-induced apoptosis in SCC1 tumors and tumor growth was significantly inhibited, whereas an agonistic effect of cetuximab on UM-SCC-22B tumor growth was observed. After cetuximab treatment, the SCC1 tumors showed decreased FDG uptake, and the UM-SCC-22B tumors had increased FDG uptake. UM-SCC-22B tumors are more responsive to (90)Y-DOTA-cetuximab treatment than SCC1 tumors, partially due to the high tumor accumulation of the injected antibody. CONCLUSION Cetuximab has an agonistic effect on the growth of UM-SCC-22B tumors, indicating that tumor response to cetuximab treatment is not necessarily related to EGFR expression and antibody delivery efficiency, as determined by PET imaging. Although PET imaging with antibodies as tracers has limited function in patient screening, it can provide guidance for targeted therapy using antibodies as delivery vehicles.

Selective Versus Comprehensive Neck Dissection after Chemoradiation for Advanced Oropharyngeal Squamous Cell Carcinoma. Otolaryngol Head Neck Surg 2009; 141:737-42.

Abstract
OBJECTIVE: To determine whether a comprehensive neck dissection (CND) or a selective neck dissection (SND) is indicated as planned post–primary chemoradiation treatment (CRT) for patients with advanced oropharyngeal squamous cell carcinoma (OPSCC). STUDY DESIGN: Case series with chart review. SETTING: A community teaching hospital. SUBJECTS: Patients with advanced OPSCC who received a uniform CRT protocol at Greater Baltimore Medical Center (GBMC). METHODS: Medical records of patients treated with primary CRT for locoregionally advanced OPSCC at GBMC between 2001 and 2007 were reviewed. All patients received 7000 to 7500, 6000, and 5000 cGy to primary disease sites, involved cervical lymphatics, and uninvolved cervical and supraclavicular lymphatics, respectively, with concomitant cisplatin (12 mg/m 2 /1 h) and 5-fluorouracil (600 mg/m 2 /20 h) given on days one through five and 29 through 33. RESULTS: Seventy-six patients received CRT, and 41 met the criteria for neck dissection. Forty-eight neck dissections were performed (34 unilateral and 7 bilateral), of which 23 (48%) were CNDs and 25 (52%) were SNDs. Residual carcinoma was found in six (26%) of the CND and five (20%) of the SND heminecks. The CND group had six (26%) complications, whereas the SND group had two (8%). CONCLUSION: The high rate of residual disease demonstrated in this study supports the need for post-CRT neck dissection. Although complication rates were not significantly different between the two groups, the trend in this study indicates that SND results in less morbidity. The presumed reduced morbidity and equivalent regional control rate suggest that SND is an appropriate surgical option for OPSCC patients after primary CRT.
