The goal of this study was to evaluate disease, survival, and toxic effects after unilateral radiation therapy treatment for tonsillar cancer.A retrospective study was performed of patients treated at our institution within the period from 2000 to 2018. Summary statistics were used to assess the cohort by patient characteristics and treatments delivered. The Kaplan-Meier method was used to determine survival outcomes.The cohort comprised 403 patients, including 343 (85%) with clinical and/or radiographic evidence of ipsilateral cervical nodal disease and 181 (45%) with multiple involved nodes. Human papillomavirus was detected in 294 (73%) tumors. Median follow-up time was 5.8 years. Disease relapse was infrequent with local recurrence in 9 (2%) patients, neck recurrence in 13 (3%) patients, and recurrence in the unirradiated contralateral neck in 9 (2%) patients. Five- and 10-year overall survival rates were 94% and 89%, respectively. Gastrostomy tubes were needed in 32 (9%) patients, and no patient had a feeding tube 6 months after therapy.For patients with well-lateralized tonsillar tumors and no clinically evident adenopathy of the contralateral neck, unilateral radiation therapy offers favorable rates of disease outcomes and a relatively low toxicity profile.

This study investigated the association of hearing loss and tinnitus with overall health-related quality of life (HRQoL) among long-term oropharyngeal cancer (OPC) survivors.This study included OPC survivors treated between 2000 and 2013 and surveyed from September 2015 to July 2016. Hearing loss and tinnitus were measured by asking survivors to rate their "difficulty with hearing loss and/or ringing in the ears" from 0 (not present) to 10 (as bad as you can imagine). Hearing loss and tinnitus scores were categorized as follows: 0 for none, 1-4 for mild, and 5-10 for moderate to severe. The primary outcome was the mean score of MD nderson Symptom Inventory HeadNeck module interference component as a HRQoL surrogate dichotomized as follows: 0 to 4 for none to mild and 5 to 10 for moderate to severe interference.Among 880 OPC survivors, 35.6% (314), reported none, 39.3% (347) reported mild, and 25.1% (221) reported moderate to severe hearing loss and tinnitus. On multivariable analysis, mild (OR, 5.83; 95% CI; 1.48-22.88; p = 0.012) and moderate (OR, 30.01; 95% CI; 7.96-113.10; p 0.001) hearing loss and tinnitus were associated with higher odds of reporting moderate to severe symptom interference scores in comparison to no hearing loss and tinnitus. This association of hearing dysfunction was consistent with all domains of HRQoL.Our findings provide preliminary evidence to support the need for continued audiological evaluations and surveillance to detect hearing dysfunction, to allow for early management and to alleviate the long-term impact on QoL.

Purpose:In locoregionally advanced, resectable cutaneous squamous cell carcinoma of the head and neck (CSCC-HN), surgery followed by radiotherapy is standard but can be cosmetically and functionally devastating, and many patients will have recurrence.Patients and Methods:Newly diagnosed or recurrent stage III–IVA CSCC-HN patients amenable to curative-intent surgery received two cycles of neoadjuvant PD-1 inhibition. The primary endpoint was ORR per RECIST 1.1. Secondary endpoints included pathologic response [pathologic complete response (pCR) or major pathologic response (MPR; ≤10% viable tumor)], safety, DSS, DFS, and OS. Exploratory endpoints included immune biomarkers of response.Results:Of 20 patients enrolled, 7 had recurrent disease. While only 6 patients [30%; 95% confidence interval (CI), 11.9–54.3] had partial responses by RECIST, 15 patients (75%; 95% CI, 50.9–91.3) had a pCR (n = 11) or MPR (n = 4). No SAEs ocurred during or after the neoadjuvant treatment. At a median follow-up of 22.6 months (95% CI, 21.7–26.1), one patient progressed and died, one died without disease, and two developed recurrence. The 12-month DSS, DFS, and OS rates were 95% (95% CI, 85.9–100), 89.5% (95% CI, 76.7–100), and 95% (95% CI, 85.9–100), respectively. Gene expression studies revealed an inflamed tumor microenvironment in patients with pCR or MPR, and CyTOF analyses demonstrated a memory CD8+ T-cell cluster enriched in patients with pCR.Conclusions:Neoadjuvant immunotherapy in locoregionally advanced, resectable CSCC-HN is safe and induces a high pathologic response rate. Pathologic responses were associated with an inflamed tumor microenvironment.

Supplementary Table from Pilot Phase II Trial of Neoadjuvant Immunotherapy in Locoregionally Advanced, Resectable Cutaneous Squamous Cell Carcinoma of the Head and Neck

Purpose:In oropharyngeal squamous cell carcinoma (OPC), high CD8+ tumor-infiltrating lymphocyte (CD8+TIL) density confers improved prognosis. We compared neoadjuvant durvalumab (PD-L1 inhibitor) with durvalumab + tremelimumab (CTLA-4 inhibitor) in terms of impact on CD8+TIL density, safety, and efficacy in patients with OPC.Patients and Methods:Patients with newly diagnosed stage II–IVA OPC or locoregionally recurrent OPC amenable to resection were included. Patients were randomized to two cycles of durvalumab or durvalumab + tremelimumab before surgery. The primary endpoint was change between baseline and resection specimen in CD8+TIL density between arms. Secondary endpoints included safety, response rate per RECIST, major pathologic response (MPR; ≤10% viable tumor cells) rate, and patient-reported outcomes.Results:Of 28 eligible patients (14/arm), 20 (71%) had newly diagnosed OPC, and 24 (86%) were p16-positive. The posttreatment to pretreatment median CD8+TIL density ratio was 1.31 for durvalumab and 1.15 for combination treatment (P = 0.97; 95% CI: −1.07–2.28). In each group, 6 patients (43%, 95% CI: 17.66–71.14) had a response. Eight patients (29%) had a MPR at the primary tumor and/or nodal metastases. Neither baseline CD8+TIL density nor PD-L1 expression level correlated with overall response, but a trend toward greater CD8+TIL change in patients with a MPR was seen (P = 0.059; 95% CI: −0.33–3.46). Four patients (14%) had grade ≥3 adverse events. At median follow-up time of 15.79 months, all patients were alive, and one had an additional recurrence.Conclusions:Durvalumab + tremelimumab did not increase CD8+TIL density more than durvalumab alone did. The observed safety and activity support further investigation of neoadjuvant checkpoint inhibitor for OPC.

We conducted this meta-analysis to address the outcomes in cancer patients after oncologic surgery during COVID-19 pandemic. The primary endpoint was the COVID-19-related mortality rate. Higher body mass index was significantly and negatively associated with higher all-cause mortality and in-hospital COVID-19 infection rates. Male sex, preoperative respiratory disease, and smoking history were positively and significantly associated with increased all-cause mortality rates. Furthermore, male sex was positively and significantly associated with the COVID-19 infection rate.

Objective The primary course of treatment for patients with low- to intermediate-risk tonsil cancer has evolved with a shift toward primary transoral robotic surgery (TORS) or radiation therapy (RT). While favorable outcomes have been reported after deintensification via unilateral TORS or RT (uniRT), comparisons of functional outcomes between these treatments are lacking. We compared clinical outcomes (Dynamic Imaging Grade of Swallowing Toxicity [DIGEST] and feeding tube [FT]) and patient-reported swallowing outcomes (MD Anderson Dysphagia Inventory [MDADI]) based on primary treatment strategy: TORS, uniRT, or bilateral RT (biRT). Study design Secondary analysis of prospective cohort. Setting Single institution. Methods The study sample comprised 135 patients with HPV/p16+ T1-T3, N0-2b (American Joint Committee on Cancer, seventh edition), N0-1 (eighth edition) squamous cell carcinoma of the tonsil were sampled from a prospective registry. Modified barium swallow studies graded per DIGEST, FT placement and duration, and MDADI were collected. Results Baseline DIGEST grade significantly differed among treatment groups, with higher dysphagia prevalence in the TORS group (34%) vs the biRT group (12%, P = .04). No significant group differences were found in DIGEST grade or dysphagia prevalence at subacute and longitudinal time points (P = .41). Mean MDADI scores were similar among groups at baseline (TORS, 92; uniRT, 93; biRT, 93; P = .90), subacute (TORS, 83; uniRT, 88; biRT, 82; P = .38) and late time points (TORS, 86; uniRT, 86; biRT, 87; P = .99). FT placement and duration significantly differed among primary treatment groups (FT [median days]: TORS, 89% [3]; uniRT, 8% [82]; biRT, 37% [104]; P Conclusion While TORS and uniRT offer optimal functional outcomes related to dysphagia, results suggest that no measurable clinician-graded or patient-reported differences in swallow outcomes exist among these primary treatment strategies and biRT. Aside from baseline differences that drive treatment selection, differences in FT rate and duration by primary treatment strategy likely reflect diverse toxicities beyond dysphagia.

OBJECTIVE: To describe the physiologic swallowing impairments (MBSImP™©) associated with safety/efficiency impairments (DIGEST(safety)/DIGEST(efficiency) grades) at 3–6 months after transoral robotic surgery (TORS) or radiation therapy (RT). STUDY DESIGN: Secondary analysis of registry data. SETTING: Single, academic institution. METHODS: Two hundred and fifty-seven patients with HPV+ oropharynx cancer were stratified by primary treatment (75 TORS, 182 RT). Modified barium swallow studies were analyzed at baseline and 3–6 months using MBSImP scores and DIGEST(safety)/DIGEST(efficiency) grades. DIGEST(safety)/DIGEST(efficiency) grades and MBSImP were compared groupwise and associations between DIGEST(safety)/DIGEST(efficiency) grades and MBSImP were explored by ordinal logistic regression. Exploratory analyses were stratified by multimodality treatment. RESULTS: Neither DIGEST(safety)/DIGEST(efficiency) differed significantly between groups at baseline or 3–6 months. Laryngeal vestibule closure was impaired more frequently in the RT group (RT: 41% vs. TORS: 27%; p = 0.02) while the TORS group had significantly more pharyngeal contraction impairment (63%; p < 0.001) compared to RT at 3–6 months. CONCLUSION: The results suggest a focal injury associated with DIGEST(safety)/DIGEST(efficiency) post-TORS in contrast to a low-level diffuse physiologic impairment associated with post-RT dysphagia.

Background The last revision of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual included a specific system for cutaneous squamous cell carcinoma (CSCC) of the head and neck. Here, we assessed the prognostic performance of six candidate modified T-classification models in head and neck CSCC patients. Methods Analysis of 916 patients with head and neck CSCC given treatment with curative intent at The University of Texas MD Anderson Cancer Center between 1995 and 2019 was performed. The main outcome was disease-specific survival (DSS), and the impact of depth of invasion (DOI) was analyzed using multivariable regression models. Candidate models were developed using the optimal DOI cut points for each AJCC T classification based on goodness of fit of the model and the simplicity of the model. Staging systems were compared using Harrell's concordance index. Results Median age was 70 years (range, 19–97years) and median follow-up time of 22 months (range, 1–250months). The median DOI was 6.0 mm (range, 0.1–70.0 mm). The five-year DSS rate was 80.7% (95%CI, 77.4–83.7%). We found significant association between DOI (hazard ratio, 1.21 [95%CI: 1.01–1.43]) and DSS on multivariable analysis. Based on a low Akaike information criterion score, improvement in the concordance index, and Kaplan–Meier curves, model 6 surpassed the AJCC staging system. Conclusions Incorporation of DOI in the current AJCC staging system improves discrimination of T classifications in head and neck CSCC patients. Lay summary The current staging system for head and neck cutaneous squamous cell carcinoma demonstrates wide prognostic variability and provides suboptimal risk stratification. Incorporation of depth of invasion in the T-classification system improves risk prediction and patient counseling. Precis We propose improved head and neck cutaneous squamous cell carcinoma T staging that will include depth of invasion and should be considered in future versions of the American Joint Committee on Cancer after external validation.

Background The prognostic performance of the recently updated American Joint Committee on Cancer lymph node classification of cutaneous head and neck squamous cell carcinoma (HNSCC) has not been validated. The objective of this study was to assess the prognostic role of extranodal extension (ENE) in cutaneous HNSCC. Methods This was a retrospective analysis of 1258 patients with cutaneous HNSCC who underwent surgery with or without adjuvant therapy between 1995 and 2019 at The University of Texas MD Anderson Cancer Center. The primary outcome was disease-specific survival (DSS). Local, regional, and distant metastases-free survival were secondary outcomes. Recursive partitioning analysis (RPA) and a Cox proportional hazards regression model were used to assess the fitness of staging models. Results No significant differences in 5-year DSS were observed between patients with pathologic lymph node-negative (pN0) disease (67.4%) and those with pN-positive/ENE-negative disease (68.2%; hazard ratio, 1.02; 95% CI, 0.61-1.79) or between patients with pN-positive/ENE-negative disease and those with pN-positive/ENE-positive disease (52.7%; hazard ratio, 0.57; 95% CI, 0.31-1.01). The RPA-derived model achieved better stratification between high-risk patients (category III, ENE-positive with >2 positive lymph nodes) and low-risk patients (category I, pN0; category II, ENE-positive/pN1 and ENE-negative with >2 positive lymph nodes). The performance of the RPA-derived model was better than that of the pathologic TNM classification (Akaike information criterion score, 1167 compared with 1176; Bayesian information criterion score, 1175 compared with 1195). Conclusions The number of metastatic lymph nodes and the presence of ENE are independent prognostic factors for DSS in cutaneous HNSCC, and incorporation of these factors in staging systems improves the performance of the American Joint Committee on Cancer lymph node classification.

Relatlimab and nivolumab combination immunotherapy improves progression-free survival over nivolumab monotherapy in patients with unresectable advanced melanoma1. We investigated this regimen in patients with resectable clinical stage III or oligometastatic stage IV melanoma (NCT02519322). Patients received two neoadjuvant doses (nivolumab 480 mg and relatlimab 160 mg intravenously every 4 weeks) followed by surgery, and then ten doses of adjuvant combination therapy. The primary end point was pathologic complete response (pCR) rate2. The combination resulted in 57% pCR rate and 70% overall pathologic response rate among 30 patients treated. The radiographic response rate using Response Evaluation Criteria in Solid Tumors 1.1 was 57%. No grade 3–4 immune-related adverse events were observed in the neoadjuvant setting. The 1- and 2-year recurrence-free survival rate was 100% and 92% for patients with any pathologic response, compared to 88% and 55% for patients who did not have a pathologic response (P = 0.005). Increased immune cell infiltration at baseline, and decrease in M2 macrophages during treatment, were associated with pathologic response. Our results indicate that neoadjuvant relatlimab and nivolumab induces a high pCR rate. Safety during neoadjuvant therapy is favourable compared to other combination immunotherapy regimens. These data, in combination with the results of the RELATIVITY-047 trial1, provide further confirmation of the efficacy and safety of this new immunotherapy regimen.

Background Postoperative complications are an independent predictor of poor survival across several tumors. However, there is limited literature on the association between postoperative morbidity and long-term survival following total laryngectomy (TL) for cancer. Methods We conducted a retrospective review of all TL patients at a single institution from 2008 to 2013. Demographic and clinical data were collected and analyzed, including postsurgical outcomes, which were classified using the Clavien-Dindo system. Multivariable Cox regression analyses were performed to identify factors associated with overall survival (OS) and disease-free survival (DFS). Results A total of 362 patients were identified. The mean age was 64 years, and the majority of patients were male (81%). The median follow-up interval was 21 months. Fifty-seven percent of patients had received preoperative radiation, and 40% had received preoperative chemotherapy. Fifty-seven percent of patients underwent salvage TL, and 60% underwent advanced reconstruction (45% free flap and 15% pedicled flap). A total of 136 patients (37.6%) developed postoperative complications, 92 (25.4%) of which were major. Multivariable modeling demonstrated that postoperative complications independently predicted shorter OS (hazard ratio [HR], 1.50; 95% CI, 1.16-1.96; P = .002) and DFS (HR, 1.36; 95% CI, 1.05-1.76; P = .021). Other independent negative predictors of OS and DFS included positive lymph node status, preoperative chemotherapy, comorbidity grade, and delayed adjuvant therapy. Severity of complication and reason for TL (salvage vs primary) were not shown to be predictive of OS or DFS. Conclusion Postoperative complications are associated with worse long-term OS and DFS relative to uncomplicated cases. Patient optimization and timely management of postoperative complications may play a critical role in long-term survival.

Treatment of cutaneous melanoma is changing with significant developments over the past several years that promise to reshape the field of melanoma surgical oncology. Modifications to the staging system based on analysis of a large international dataset, the timing and extent of regional lymphadenectomy, the emergence of effective systemic therapies in the neoadjuvant and adjuvant setting, and the role of adjuvant radiation are all undergoing a data-driven evolution. Surgeon engagement in multidisciplinary decision making remains an essential component of contemporary management for patients across all stages of melanoma and demands specific involvement of head and neck surgical oncologists.

Purpose: In oropharyngeal squamous cell carcinoma (OPC), high CD8+ tumor-infiltrating lymphocyte (CD8+TIL) density confers improved prognosis. We compared neoadjuvant durvalumab (PD-L1 inhibitor) with durvalumab + tremelimumab (CTLA-4 inhibitor) in terms of impact on CD8+TIL density, safety, and efficacy in patients with OPC. Patients and Methods: Patients with newly diagnosed stage II–IVA OPC or locoregionally recurrent OPC amenable to resection were included. Patients were randomized to two cycles of durvalumab or durvalumab + tremelimumab before surgery. The primary endpoint was change between baseline and resection specimen in CD8+TIL density between arms. Secondary endpoints included safety, response rate per RECIST, major pathologic response (MPR; ≤10% viable tumor cells) rate, and patient-reported outcomes. Results: Of 28 eligible patients (14/arm), 20 (71%) had newly diagnosed OPC, and 24 (86%) were p16-positive. The posttreatment to pretreatment median CD8+TIL density ratio was 1.31 for durvalumab and 1.15 for combination treatment (P = 0.97; 95% CI: −1.07–2.28). In each group, 6 patients (43%, 95% CI: 17.66–71.14) had a response. Eight patients (29%) had a MPR at the primary tumor and/or nodal metastases. Neither baseline CD8+TIL density nor PD-L1 expression level correlated with overall response, but a trend toward greater CD8+TIL change in patients with a MPR was seen (P = 0.059; 95% CI: −0.33–3.46). Four patients (14%) had grade ≥3 adverse events. At median follow-up time of 15.79 months, all patients were alive, and one had an additional recurrence. Conclusions: Durvalumab + tremelimumab did not increase CD8+TIL density more than durvalumab alone did. The observed safety and activity support further investigation of neoadjuvant checkpoint inhibitor for OPC.

Practices in surgical oncology had to change in response to these resource limitations, triaging based on acuity, expected oncologic outcomes, availability of supportive resources, and safety of health care personnel.MethodsThe MD Anderson Head and Neck Surgery Treatment Guidelines Consortium devised the following to provide guidance on triaging head and neck cancer (HNC) surgeries based on multidisciplinary consensus. HNC subsites considered included aerodigestive tract mucosa, sinonasal, salivary, endocrine, cutaneous, and ocular.RecommendationsEach subsite is presented separately with disease-specific recommendations. Options for alternative treatment modalities are provided if surgical treatment needs to be deferred.ConclusionThese guidelines are intended to help clinicians caring for patients with HNC appropriately allocate resources during a health care crisis, such as the COVID-19 pandemic. We continue to advocate for individual consideration of cases in a multidisciplinary fashion based on individual patient circumstances and resource availability.

Background In the face of the COVID‐19 pandemic, cancer care has had to adapt rapidly given the Centers for Disease Control and Prevention and the American College of Surgeons (ACS) issuing recommendations to postpone nonurgent surgeries. Methods An institutional multidisciplinary group of Head and Neck Surgical Oncology, Surgical Endocrinology, and Medical Endocrinology devised Surgical Triaging Guidelines for Endocrine Surgery during COVID‐19, aligned with phases of care published by the ACS. Results Phases of care with examples of corresponding endocrine cases are outlined. Most cases can be safely postponed with active surveillance, including most differentiated and medullary thyroid cancers. During the most acute phase, all endocrine surgeries are deferred, except thyroid tumors requiring acute airway management. Conclusions These guidelines provide context for endocrine surgery within the spectrum of surgical oncology, with the goal of optimal individualized multidisciplinary patient care and the expectation of significant resource diversion to care for patients with COVID‐19.

Background This study reports long-term head and neck cancer (HNC) patient-reported symptoms using the MD Anderson Symptom Inventory Head and Neck Cancer Module (MDASI-HN) in a large cohort of HNC survivors. Methods MDASI-HN results were prospectively collected from an institutional survivorship database. Associations with clinicopathologic data were analyzed using χ2 , Mann-Whitney, and univariate regression. Results Nine hundred and twenty-eight patients were included. Forty-six percent had oropharyngeal primary tumors. Eighty-two percent had squamous cell carcinoma. Fifty-six percent of patients had ablative surgery and 81% had radiation therapy as a component of treatment. The most severe symptoms were xerostomia and dysphagia. Symptom scores were worst for hypopharynx and varied by subsite. Patients treated with chemoradiation or surgery followed by radiation ± chemotherapy reported the worst symptoms while patient treated with surgery plus radiation ± chemotherapy reported the worst interference. Conclusion HNC survivors describe their long-term symptom burden and inform efforts to improve care many years into survivorship.

BACKGROUND: The study objective is to identify risk factors associated with fatigue among long-term OPC survivors. METHODS: This cross-sectional study included disease-free OPC survivors treated curatively between 2000 and 2013 who were surveyed from September 2015 to July 2016. The outcome variable was patient-reported fatigue. Multivariable logistic regression was used to identify factors associated with moderate to severe fatigue. RESULTS: Among 863 OPC survivors, 17.4% reported moderate to severe fatigue. Self-reported thyroid problems (OR: 2.01; p = 0.003), current cigarette smoking at time of survey (OR: 3.85; p = 0.001), late lower cranial neuropathy (OR: 3.44; p = 0.002), and female sex (OR: 1.91; p = 0.010) were concurrent risk factors of reporting moderate to severe fatigue. Ipsilateral intensity-modulated radiotherapy (OR: 0.18; p = 0.014) was associated with lower risk of reporting moderate to severe fatigue. CONCLUSIONS: Our study identified thyroid problems, smoking, and late lower cranial neuropathy as associated with moderate to severe fatigue. These findings should be further validated in prospective studies to address fatigue among OPC survivors.

Genetic susceptibility for xerostomia, a common sequela of radiotherapy and chemoradiotherapy for head and neck cancer, is unknown. Therefore, to identify genetic variants associated with moderate to severe xerostomia, we conducted a GWAS of 359 long-term oropharyngeal cancer (OPC) survivors using 579,956 autosomal SNPs. Patient-reported cancer treatment-related xerostomia was assessed using the MD Anderson Symptom Inventory. Patient response was dichotomized as moderate to severe or none to mild symptoms. In our study, 39.2% of OPC survivors reported moderate to severe xerostomia. Our GWAS identified eight SNPs suggestively associated with higher risk of moderate to severe xerostomia in six genomic regions (2p13.3, rs6546481, Minor Allele (MA) = A, ANTXR1, P = 4.3 × 10–7; 5p13.2–p13.1, rs16903936, MA = G, EGFLAM, P = 5.1 × 10–6; 4q21.1, rs10518156, MA = G, SHROOM3, P = 7.1 × 10–6; 19q13.42, rs11882068, MA = G, NLRP9, P = 1.7 × 10–5; 12q24.33, rs4760542, MA = G, GLT1D1, P = 1.8 × 10–5; and 3q27.3, rs11714564, MA = G, RTP1, P = 2.9 × 10–5. Seven SNPs were associated with lower risk of moderate to severe xerostomia, of which only one mapped to specific genomic region (15q21.3, rs4776140, MA = G, LOC105370826, a ncRNA class RNA gene, P = 1.5 × 10–5). Although our small exploratory study did not reach genome-wide statistical significance, our study provides, for the first time, preliminary evidence of genetic susceptibility to xerostomia. Further studies are needed to elucidate the role of genetic susceptibility to xerostomia.

Background This study was conducted to identify clinicodemographic risk factors for xerostomia among long-term oropharyngeal cancer (OPC) survivors. Methods This cross-sectional study included 906 disease-free, adult OPC survivors with a median survival duration at the time of survey of 6 years (range, 1-16 years); self-reported xerostomia scores were available for 877 participants. Study participants had completed curative treatment between January 2000 and December 2013 and responded to a survey administered from September 2015 to July 2016. The primary outcome variable was cancer patient-reported xerostomia measured with the MD Anderson Symptom Inventory Head and Neck Cancer Module. Clinicodemographic risk factors for moderate to severe xerostomia were identified via multivariable logistic regression. Results Moderate to severe xerostomia was reported by 343 of the respondents (39.1%). Female sex (odds ratio [OR], 1.82; 95% CI, 1.22-2.71; P = .003; Bayesian false-discovery probability [BFDP] = 0.568), high school or lower education (OR, 1.73; 95% CI, 1.19-2.52; P = .004; BFDP = 0.636), and current cigarette smoking at the time of survey (OR, 2.56; 95% CI, 1.19-5.47; P = .016; BFDP = 0.800) were risk factors for moderate to severe xerostomia, and bilateral intensity-modulated radiotherapy (IMRT) combined with proton therapy and ipsilateral IMRT were protective. Conclusions In this large xerostomia study, modern radiotherapy was a protective factor, and continued cigarette smoking at the time of survey, female sex, and high school or lower education were identified as other contributing risk factors associated with moderate to severe xerostomia. Importantly, these findings need to be confirmed in prospective studies. These results can inform future research and targeted patient-centered interventions to monitor and manage radiation therapy-associated xerostomia and preserve quality of life among patients with OPC.

PurposeTo report on the outcomes of immunotherapy in patients with locally advanced periorbital squamous cell carcinoma.MethodsWe performed a retrospective chart review of seven consecutive patients with locally advanced periorbital cutaneous squamous cell carcinoma treated with anti-PD-1 immunotherapy. Treatments and therapeutic outcomes were reviewed.ResultsOf the seven patients, six were treated with cemiplimab, and one was treated with pembrolizumab. Five patients were treated with immunotherapy as neoadjuvant therapy before planned surgical resection; two patients received immunotherapy for treatment of advanced recurrent lesions deemed unresectable following multiple previous excisions and radiation therapy. In all seven patients, measurable clinical and/or radiologic response was observed.ConclusionsOur findings support the emerging role of anti-PD-1 immunotherapy in the management of locally advanced periorbital cutaneous squamous cell carcinoma.

Purpose: In locoregionally advanced, resectable cutaneous squamous cell carcinoma of the head and neck (CSCC-HN), surgery followed by radiotherapy is standard but can be cosmetically and functionally devastating, and many patients will have recurrence. Patients and Methods: Newly diagnosed or recurrent stage III–IVA CSCC-HN patients amenable to curative-intent surgery received two cycles of neoadjuvant PD-1 inhibition. The primary endpoint was ORR per RECIST 1.1. Secondary endpoints included pathologic response [pathologic complete response (pCR) or major pathologic response (MPR; ≤10% viable tumor)], safety, DSS, DFS, and OS. Exploratory endpoints included immune biomarkers of response. Results: Of 20 patients enrolled, 7 had recurrent disease. While only 6 patients [30%; 95% confidence interval (CI), 11.9–54.3] had partial responses by RECIST, 15 patients (75%; 95% CI, 50.9–91.3) had a pCR (n = 11) or MPR (n = 4). No SAEs ocurred during or after the neoadjuvant treatment. At a median follow-up of 22.6 months (95% CI, 21.7–26.1), one patient progressed and died, one died without disease, and two developed recurrence. The 12-month DSS, DFS, and OS rates were 95% (95% CI, 85.9–100), 89.5% (95% CI, 76.7–100), and 95% (95% CI, 85.9–100), respectively. Gene expression studies revealed an inflamed tumor microenvironment in patients with pCR or MPR, and CyTOF analyses demonstrated a memory CD8+ T-cell cluster enriched in patients with pCR. Conclusions: Neoadjuvant immunotherapy in locoregionally advanced, resectable CSCC-HN is safe and induces a high pathologic response rate. Pathologic responses were associated with an inflamed tumor microenvironment.

Identifying tumor characteristics that correlate with metastasis and survival in patients with conjunctival melanoma can potentially lead to better outcomes through a better selection of patients for adjuvant treatments including potentially life-saving new melanoma therapy. The objective of this study was to validate the conjunctival melanoma staging criteria in the American Joint Committee on Cancer (AJCC) Cancer Staging Manual (8th edition) and explore the prognostic importance of tumor thickness, histologic ulceration, and sentinel lymph node biopsy (SLNB) findings in patients with conjunctival melanoma. This is a case series of 88 consecutive patients with conjunctival melanoma. Clinicopathologic characteristics were analyzed. Associations between pathologic characteristics and outcomes were studied using Kaplan-Meier survival analysis. Local recurrence, lymph node metastasis, distant metastasis, and disease-specific survival (DSS) were the main outcome measures. The study included 56 women and 32 men; the median age was 62 years. At presentation, 41 patients had T1 disease, 23 had T2 disease, 23 had T3, and 1 had T4 disease. Sixty-six patients had invasive conjunctival melanoma (median thickness, 1.56 mm), 17 had conjunctival melanoma in situ, and in 5 patients, tumor thickness could not be determined. Overall, 22 patients had ulceration. In total, 31 patients underwent SLNB, and 4 had a positive sentinel lymph node (SLN). The median follow-up time was 46.6 months. Overall, 12 patients had nodal metastasis at presentation or during follow-up, 19 patients had distant metastasis at last follow-up, and 14 patients died of the disease. Tumor thickness and ulceration were associated with increased risks of nodal metastasis, distant metastasis, and death from the disease. Overall, greater clinical T category at presentation was associated with increased risks of distant metastasis and disease-related death; however, the risks of distant metastasis and disease-related death did not differ between T1 (bulbar) and T2 (nonbulbar) tumors or between T2c,d (caruncular) and T1-T2a,b (noncaruncular) tumors. In patients who underwent SLNB, a positive SLN was associated with worse distant metastasis free survival and DSS. Consideration should be given to adding ulceration and emphasizing tumor thickness as the main determinants of pathologic T category for conjunctival melanoma in future AJCC classifications. The significant association between a positive SLN and worse DSS highlights the importance of SLNB for prognosis in patients with conjunctival melanoma and selecting high-risk patients for adjuvant drug treatment.

Background: When achieved, complete surgical resection improves outcomes in anaplastic thyroid carcinoma (ATC). However, most ATC patients present with advanced inoperable disease, often with impending airway obstruction, increased hemorrhage risk, and significant dysphagia. Novel treatment strategies are critically needed to improve disease control and decrease locoregional morbidity. The objective of this study was to determine the feasibility and effectiveness of a neoadjuvant regimen by using dabrafenib with trametinib followed by surgical resection in patients with initially unresectable BRAFV600E-mutated ATC. Methods: Case series of six consecutive patients with BRAFV600E-mutated ATC diagnosed between January 2017 and February 2018. Pathologic confirmation of ATC was obtained before treatment. BRAFV600E status was ascertained via immunohistochemistry or sequencing of circulating tumor DNA. All patients received dabrafenib and trametinib (DT) followed by surgical resection and adjuvant chemoradiation. Three patients also received pembrolizumab. Results: Complete surgical resection was achieved in all patients. Histopathologic analyses of resected specimens showed high pathologic response rates with significantly decreased ATC viability and residual papillary thyroid carcinoma components. Overall survival at six months and one year was 100% and 83%, respectively. Locoregional control rate was 100%. Two patients died of distant metastases without evidence of locoregional disease at 8 and 14 months from diagnosis. The remaining four patients had no evidence of disease at the last follow-up. Conclusions: We report the first series in the literature of BRAFV600E-mutated ATC patients with locoregionally advanced disease treated with DT followed by surgical resection. We demonstrated feasibility of complete resection, decreased need for tracheostomy, high pathologic response rates, and durable locoregional control with symptom amelioration.

Spiradenoma and cylindroma are related sweat gland tumors. To delineate their histogenesis, gene profiles, and their potential drivers, we performed a whole-transcriptome sequencing analysis of fourteen samples of spiradenoma/cylindroma in comparison to normal samples. A total of 12 spiradenomas, 5 cylindromas, 3 hybrid spiradenomas/cylindromas and 2 adnexal carcinomas were included in this study. 1335 characteristic genes and transcripts expressed over all 14 spiradenoma/cylindroma tumors were identified, and two groups of expression profiles were observed. Highest upregulated top 7 gene signatures characterized benign tumors with developmental and differentiation related genes, and carcinomas with top 7 genes mainly related to signaling, reorganization and metabolism of membranes. Immunohistochemistry of protein expressions validated 4 upregulated genes (ODAM, HOXB13, MYB and SOX10) considered important and as potential biomarkers for spiradenomas and cylindromas. We further compared the transcriptome of eccrine adnexal tumors with the transcriptome of adenoid cystic carcinoma (ACC) to identify the overlapping genes that may indicate histogenesis. There were 36 specific genes overlapping between adnexal carcinomas and the epithelial-dominant subtype of ACC, and 27 specific genes overlapping benign adnexal tumors with the myoepithelial-dominant subtype of ACC, At this point there is no known specific biomarker to aid in the diagnosis of eccrine spiradenoma and cylindroma in small samples or biopsies within the context of morphological overlap with ACC. In conclusion, spiradenomas and cylindromas are characterized by overexpressed developmental genes, where LHX2 and activated WNT signaling possibly drive associated carcinomas.

Background The survival benefit of elective neck dissection (END) for patients with cutaneous squamous cell carcinoma (cSCC) of the head and neck and no evidence of regional metastasis (cN0) has never been reported. The aim of this study was to determine the effect of END on patient survival. Methods The authors included patients with head and neck cSCC who had undergone primary surgery from 1995 to 2017. The primary end point was survival, and the secondary end points were the incidence of occult regional disease and regional disease control. To assess the impact of END on survival, the authors used multivariable Cox proportional hazards models with propensity score and matching techniques for internal validation. Results A total of 1111 patients presented with no evidence of nodal disease; 173 had END, and 938 were observed. Adjuvant radiotherapy to the neck was administered to 101 patients (9%). END resulted in a 5-year overall survival rate of 52%, whereas the rate was 63% in the observation group (P = .003 [log-rank]). The 5-year disease-free survival rate for patients undergoing END was similar to that for the observation group (73% vs 75%; P = .429). A multivariate regression model showed that the performance of END was not associated with improved rates of overall, disease-specific, or disease-free survival; similarly, among patients with advanced disease (T3-4), those who underwent END did not have improved survival rates. Conclusions Among patients with cSCC of the head and neck, observation of the neck nodes resulted in noninferior survival rates in comparison with END at the time of primary surgery. Further studies are required to elucidate the role of END in patients with advanced disease.

BACKGROUND: Management of patients with sentinel lymph node (SLN) positive melanoma has changed dramatically in the last few years such that completion lymph node dissection (CLND) has become uncommon, and many patients receive adjuvant immunotherapy or targeted therapy. This study seeks to characterize patterns and predictors of early recurrence in this setting. METHODS: All patients with primary cutaneous melanoma undergoing sentinel lymph node biopsy (SLNB) between 3/2016–12/2019 were identified. The subset with a positive SLN who did not undergo CLND were examined for further analysis of outcomes and predictors of recurrence. RESULTS: Overall, 215 patients with SLN-positive melanoma who did not have CLND were identified. Adjuvant systemic therapy was administered to 102 (47%), with 93% of this subset receiving immunotherapy (n=95). Median follow-up from SLNB was 20 months (IQR 12–28.5 months); 57 patients (27%) recurred during this time. The SLN basin was the most common site of recurrence (n=38, 67% of recurrence), with isolated nodal recurrence being the most common first site of recurrent disease (n=22, 39% of recurrence). On multivariable analysis, lymphovascular invasion (LVI) of the primary tumor, 2 or more involved nodes and >1 mm nodal deposit were independently associated with higher rates of nodal relapse. CONCLUSION: Nodal recurrence is a primary driver of early disease relapse for patients with SLN-positive melanoma who do not undergo CLND in the era of effective adjuvant systemic therapy. LVI, ≥2 nodes or >1 mm nodal disease identify patients at particularly high risk of nodal relapse.

Recognizing rare but clinically significant toxicity of immunotherapy is critical. Here we describe the first detailed case of severe osteonecrosis of the jaw due to anti-PD-1. A 75-year-old man with metastatic melanoma, with no prior radiation or treatment with bone-targeting agents, experienced jaw pain 1 week after his first dose of nivolumab. Imaging studies were negative, and treatment was resumed after pain was controlled. 4 months later, the patient experienced acute exacerbation of pain and malocclusion of the jaw. Imaging showed bilateral fractures of the angle of mandible with extensive disruption of the normal trabecular architecture, requiring total mandibulectomy. The patient’s metastatic melanoma responded to treatment and remains controlled >20 months after treatment cessation without further therapy.

IMPORTANCE: Anaplastic thyroid carcinoma (ATC) historically has a 4-month median overall survival (OS) from time of diagnosis, with disease-specific mortality approaching 100%. The association between recent major advancements in treatment and OS has yet to be evaluated. OBJECTIVE: To evaluate rates of OS in patients with ATC over the last 2 decades. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study in a single tertiary care institution. Patients with histopathological confirmation of ATC from January 2000 to October 2019 were included and divided into 3 groups according to date of presentation: 2000-2013, 2014-2016, and 2017-2019. MAIN OUTCOMES AND MEASURES: Overall survival compared among different treatment eras and differing therapies, including targeted therapy, immunotherapy, and surgery. RESULTS: Of 479 patients (246 men [51%]; median age, 65.0 [range, 21.1-92.6] years) with ATC evaluated, 52 (11%) were stage IVA, 172 (36%) stage IVB, and 255 (53%) stage IVC at presentation. The median OS of the entire cohort was 0.79 years (9.5 months), ranging from 0.01 to 16.63. The OS at 1 and 2 years was 35% (95% CI, 29%-42%) and 18% (95% CI, 13%-23%) in the 2000-2013 group (n = 227), 47% (95% CI, 36%-56%) and 25% (95% CI, 17%-34%) in the 2014-2016 group (n = 100), and 59% (95% CI, 49%-67%) and 42% (95% CI, 30%-53%) in the 2017-2019 group (n = 152), respectively (P

Highlights • The use of oral stents during RT was associated with reduced late morbidity. • OPC patients with bilateral RT and tongue-depressing stents had less dysphagia. • Patients with unilateral RT and tongue-deviating stent had better taste/appetite., Objectives To evaluate whether the use of oral stents during intensity modulated radiation therapy (IMRT) for oropharyngeal cancer (OPC) is associated with long-term patient reported symptoms. Materials and methods Data was obtained from a prospective observational study of disease-free head and neck cancer survivors. Radiation-associated patient reported symptoms were assessed using the MD Anderson Symptom Inventory Head and Neck module (MDASI-HN). Scores of ≥5 (11-point Likert scale, 0-10) were considered moderate/severe. Stratification was performed regarding IMRT volume (uni- versus bilateral neck) and stent utilization, with non-parametric analyses between groups. Results 462 OPC survivors formed the cohort (54% tonsil, 46% base of tongue primaries). A tongue-deviating stent was used in 17%, tongue-depressing stent in 46%, and no stent in 37%. Median prescribed dose to the high dose clinical target volume was 66.0 Gy. Median follow-up from RT to MDASI-HN assessment was 68 months. Twenty percent had received unilateral neck RT (all had tonsil primaries), in whom a significant improvement in the proportion of patients with moderate/severe taste impairment (2% vs. 15%, p = 0.047) and lack of appetite (0% vs. 9%, p = 0.019) was associated with the use of tongue-deviating stents compared to no oral stent. In those who had received bilateral neck RT, a significant improvement in the proportion of patients with moderate/severe difficulty swallowing/chewing was associated with use of a tongue-depressing stent (21% vs. 31% without oral stent, p = 0.013). Conclusion Disease-site specific select use of oral stents during IMRT was associated with reduced long-term patient reported symptoms in OPC survivors.

Highlights • The majority of OPC patients are affected from late taste impairment after RT. • Taste markedly improved in the first years from end of RT, but plateaued after year 5. • Treatment site, CTV1 dose and age might have an influence on taste impairment., Background and purpose Taste impairment is a common radiation-induced toxicity in head and neck cancer (HNC) patients acutely. However, data on the potential for recovery and the time dependent course of late taste impairment are limited. Materials and methods As part of an IRB-approved observational prospective study, HNC patients underwent serial surveys including the MD Anderson Symptom Inventory - Head and Neck module (MDASI-HN). For our analysis, we extracted MDASI-HN taste item results from oropharyngeal cancer patients treated with intensity-modulated radiotherapy or volumetric modulated arc therapy and at least two taste assessments after ≥1 year from end of radiotherapy (RT). Results 1214 MDASI taste items from 326 patients between 1 and 13 years post-RT were included. Median prescribed dose to the high-dose clinical target volume (CTV1) was 66.0 Gy, with 180 patients (55%) receiving chemotherapy. Taste markedly improved in the first years from end of RT, but plateaued after year 5. In patients with taste assessment in subsequent years, a significant reduction in taste impairment was found from the second to the third year (p = 0.001) and tended towards significance from the third to the fourth year (p = 0.058). Multivariate analysis revealed treatment site as significant factor in the sixth year from RT and CTV1 dose and age in the seventh year. Conclusion Radiation-induced taste impairment may improve over an extended time interval, but becomes relatively stable from year 5 post-RT. Direct characterization of RT-induced taste impairment and the calculation of normal tissue complication probability should include consideration of the time-dependent course in taste recovery.

The American Joint Committee on Cancer Cancer Staging System for differentiated thyroid cancer has been recently revised. The purpose of this study was to compare survival prognostication between the seventh and eighth editions.We retrospectively reviewed 2579 differentiated thyroid cancer patients who underwent surgery at MD Anderson Cancer Center between 2000 and 2015. Disease-specific survival (DSS) and overall survival were estimated using the Kaplan-Meier method and compared using log rank test. The effect of potential predictor was estimated using Cox proportional hazards model. Power of survival prediction was estimated using Harrell's C concordance index (C-index), and predictive capacities for DSS were estimated using proportion of variance explained (PVE).Revision of tumor-node-metastasis (TNM) categories, age cutoff, and stage reassignment in the 8The AJCC eighth edition is similar to the seventh edition in disease-specific survival prediction. Potential modifications that may improve disease-specific survival prediction in future renditions include reconsideration of T3b tumor category and upstaging classification of patients55 years of age with distant metastases.

PURPOSE: In oropharyngeal squamous cell carcinoma (OPC), high CD8-positive tumor-infiltrating lymphocytes (CD8(+)TIL) density confers improved prognosis. We compared neoadjuvant durvalumab (PD-L1 inhibitor) with durvalumab plus tremelimumab (CTLA-4 inhibitor) in terms of impact on CD8(+)TIL density, safety, and efficacy in OPC patients. PATIENTS AND METHODS: Patients with newly diagnosed stage II-IVA OPC or locoregionally-recurrent OPC amenable to resection were included. Patients were randomized to two cycles of durvalumab or durvalumab plus tremelimumab before surgery. The primary endpoint was change between baseline and resection specimen in CD8(+)TIL density between arms. Secondary endpoints included safety, response rate per RECIST, major pathologic response (MPR; ≤10% viable tumor cells) rate, and patient-reported outcomes. RESULTS: Of 28 eligible patients (14 per arm), 20 (71%) had newly diagnosed OPC, and 24 (86%) were p16-positive. The posttreatment to pretreatment median CD8(+)TIL density ratio was 1.31 for durvalumab and 1.15 for combination treatment (P=.97, 95%CI:(−1.07,2.28)). In each group, 6 patients (43%, 95%CI:(17.66,71.14)) had a response. Eight patients (29%) had a MPR at the primary tumor and/or nodal metastases. Neither baseline CD8(+)TIL density nor PD-L1 expression level correlated with overall response, but a trend toward greater CD8(+)TIL change in patients with a MPR was seen (P=.059, 95%CI:(−0.33,3.46)). Four patients (14%) had grade ≥3 adverse events. At median follow-up time of 15.79 months, all patients were alive, and one had an additional recurrence. CONCLUSIONS: Durvalumab plus tremelimumab did not increase CD8(+)TIL density more than durvalumab alone did. The observed safety and activity support further investigation of neoadjuvant checkpoint inhibitor for OPC. Clinicaltrials.gov identifier NCT03144778

Background Functional outcomes after treatment for oropharyngeal squamous cell carcinoma (SCC) are increasingly prioritized. The purpose of this study was to investigate the incidence of gastrostomy tube placement and weight loss in patients with oropharyngeal SCC who may be eligible for either transoral robotic surgery (TORS) or nonsurgical management. Methods We conducted a retrospective review of previously untreated T1 to T2 and N0 to N2b oropharyngeal SCC to determine the rates of gastrostomy tube placement and weight loss according to Common Terminology Criteria for Adverse Events (CTCAE) criteria. Multivariate regression models were fit to compare these end points between groups. Results Two hundred twenty-three patients were included, comprised of 66 patients who underwent TORS and 157 patients who underwent (chemo)radiation. Thirty-two (48.5%) of the TORS patients received adjuvant radiation. On multivariate analysis, patients treated nonsurgically were 10.6 times and 8.1 times more likely to receive a gastrostomy tube and experience greater than CTCAE grade 1 weight loss, respectively. Conclusion In selected patients with oropharyngeal SCC, TORS may help avoid critical weight loss and gastrostomy tube placement in the acute treatment period.

Management of differentiated thyroid carcinoma (DTC) is gradually evolving with considerations of de-escalation of treatment and/or active surveillance in a significant proportion of patients on the basis of an improved understanding of the long-term disease and functional outcomes from both surgical and non-surgical approaches. This is fueled by improved risk stratification using clinicopathologic prognostic factors as determined through high resolution ultrasound and fine needle aspiration cytology. This paper discusses general recommendations for preoperative decision-making in the management of the central compartment in DTC with particular reference to micropapillary thyroid carcinoma and encapsulated follicular variant papillary thyroid carcinoma. Given the multitude of specific factors that must be considered for each patient, therapeutic decisions should occur in a multidisciplinary setting weighing the risks of treatment morbidity against the risks of disease progression or recurrence. Recurrent/persistent disease merits special attention with regard to pre-operative planning and surgical risk, and should be managed by high-volume thyroid surgeons.

To identify a clinically meaningful cut-point for the single item dry mouth question of the MD Anderson Symptom Inventory-Head and Neck module (MDASI-HN).Head and neck cancer survivors who had received radiation therapy (RT) completed the MDASI-HN, the University of Michigan Hospital Xerostomia Questionnaire (XQ), and the health visual analog scale (VAS) of the EuroQol Five Dimension Questionnaire (EQ-5D). The Bayesian information criteria (BIC) were used to test the prediction power of each tool for EQ-5D VAS. The modified Breiman recursive partitioning analysis (RPA) was used to identify a cut point of the MDASI-HN dry mouth score (MDASI-HN-DM) with EQ-5D VAS, using a ROC-based approach; regression analysis was used to confirm the threshold effect size.Two-hundred seven respondents formed the cohort. Median follow-up from the end of RT to questionnaire completion was 88 months. The single item MDASI-HN-DM score showed a linear relationship with the XQ composite score (ρ = 0.80, p 0.001). The MDASI-HN-DM displayed improved model performance for association with EQ-5D VAS as compared to XQ (BIC of 1803.7 vs. 2016.9, respectively). RPA showed that an MDASI-HN-DM score of ≥6 correlated with EQ-5D VAS decline (LogWorth 5.5).The single item MDASI-HN-DM correlated with the multi-item XQ and performed favorably in the prediction of QOL. A MDASI-HN-DM cut point of ≥6 correlated with decline in QOL.
