Impact of Neurolens Use on the Quality of Life in Individuals With Headaches: A Randomized Double-Masked, Cross-Over Clinical Trial.

Purpose: Vision-related disorders, such as refractive errors and binocular vision issues, can cause headaches. The current study evaluates the impact of Neurolens (NL) on individuals with headaches, assessed using the Headache Impact Test (HIT) questionnaire. Methods: Subjects (18-60 years) with good stereoacuity and a HIT score of ≥56 points were enrolled. Each subject wore both control lens and NL for 30 ± 10 days each. The primary outcome of the study was to assess the difference in the HIT score between the two treatments. Results: Of the subjects randomized, 88% (170/195) completed the study. Overall, subjects reported a greater improvement in HIT score improvement with NL compared with control (mean difference, -1.53 points; 95% confidence interval, -2.8 to -0.26; P = 0.01). In the subgroup with reduced NPC, subjects reported a larger improvement in HIT score improvement with NL but was not statistically significant (mean difference, -1.89 points; 95% confidence interval, -4.27 to -0.47; P = 0.11). Conclusions: NL produced a statistically significant decrease in the impact of headaches on individuals' quality of life compared with placebo. Although the overall magnitude of the decrease was not clinically significant, a clinically meaningful improvement with NL cannot be ruled out with high certainty in the current study. Translational Relevance: Headache is one of the most experienced symptoms by individuals worldwide with vision-related disorders being a primary reason. It is, therefore, critical to screen these disorders before providing a pharmacological intervention, which may have side effects. NL provides an objective way to diagnose and treat digital eyestrain-related headaches.

CNS Efficacy of Osimertinib With or Without Chemotherapy in Epidermal Growth Factor Receptor-Mutated Advanced Non-Small-Cell Lung Cancer.

PURPOSE: We report CNS efficacy of first-line osimertinib plus chemotherapy versus osimertinib monotherapy in patients with epidermal growth factor receptor (EGFR)-mutated advanced non-small-cell lung cancer (NSCLC) from the phase III FLAURA2 study according to baseline CNS metastasis status. METHODS: Patients were randomly assigned to osimertinib plus platinum-pemetrexed (combination) or osimertinib monotherapy until disease progression or discontinuation. Brain scans were performed in all patients at baseline and progression and at scheduled assessments until progression for patients with baseline CNS metastases; scans were assessed by neuroradiologist CNS blinded independent central review (BICR). RESULTS: On the basis of baseline CNS BICR, 118 of 279 (combination) and 104 of 278 (monotherapy) randomly assigned patients had ≥one measurable and/or nonmeasurable CNS lesion and were included in the CNS full analysis set (cFAS); 40 of 118 and 38 of 104 had ≥one measurable target CNS lesion and were included in the post hoc CNS evaluable-for-response set (cEFR). In the cFAS, the hazard ratio (HR) for CNS progression or death was 0.58 (95% CI, 0.33 to 1.01). In patients without baseline CNS metastases, the HR for CNS progression or death was 0.67 (95% CI, 0.43 to 1.04). In the cFAS, CNS objective response rates (ORRs; 95% CI) were 73% (combination; 64 to 81) versus 69% (monotherapy; 59 to 78); 59% versus 43% had CNS complete response (CR). In the cEFR, CNS ORRs (95% CI) were 88% (73 to 96) versus 87% (72 to 96); 48% versus 16% had CNS CR. CONCLUSION: Osimertinib plus platinum-pemetrexed demonstrated improved CNS efficacy compared with osimertinib monotherapy, including delaying CNS progression, irrespective of baseline CNS metastasis status. These data support this combination as a new first-line treatment for patients with EGFR-mutated advanced NSCLC, including those with CNS metastases.

Impact of comorbidities on outcomes in patients with advanced head and neck cancer undergoing immunotherapy.

OBJECTIVES: To explore the impact of pre-existing comorbidities on immunotherapy response, overall and progression-free survival, and immune-related adverse events (irAEs) of patients with advanced head and neck cancer (HNC) treated with immunotherapy. PATIENTS AND METHODS: Ninety-three patients treated with immunotherapy were identified and stratified into comorbidity absent or present (CCI < 1 and CCI ≥ 1, respectively) cohorts, and clinical outcomes were compared between these two groups. RESULTS: Patients with no comorbidities had longer overall survival (aHR = 2.74, 95% CI [1.18, 6.40], p = 0.02) and progression-free survival (aHR = 2.07, 95% CI [1.03, 4.16], p = 0.04) and a higher tumor response rate (32% in CCI < 1 vs. 14% in CC ≥ 1, p = 0.05). Risk for irAEs was higher in the comorbidity absent group (p = 0.05). CONCLUSION: Comorbidity should be considered as a significant prognostic factor in clinical decision-making for patients with advanced HNC undergoing immunotherapy.

The Effects of Growth Hormone on Nerve Regeneration and Alloimmunity in Vascularized Composite Allotransplantation.

BACKGROUND: Poor outcomes in functional recovery following upper extremity transplantation are largely due to denervation-induced muscle atrophy that occurs during the prolonged period of nerve regeneration. Growth hormone (GH) has well-established trophic effects on neurons, myocytes, and Schwann cells and represents a promising therapeutic approach to address this challenge. This study sought to confirm the positive effects of GH treatment on nerve regeneration and functional recovery and to evaluate the effects of GH treatment on the immune response in the setting of vascularized composite allotransplantation. METHODS: Rats underwent orthotopic forelimb transplantation across a full MHC-mismatch and received either porcine-derived growth hormone or no treatment (n=18 per group). Functional recovery was measured using electrically-stimulated grip strength testing. Animals were monitored for clinical and subclinical signs of rejection. RESULTS: Neuromuscular junction reinnervation and grip strength were improved in GH-treated animals (p=0.005; p=0.08). No statistically significant differences were seen in muscle atrophy, degree of myelination, axon diameter, and axon counts between groups. The rates of clinical and histological rejection did not significantly differ among groups. CONCLUSIONS: Our findings alleviate concern for increased risk of transplant rejection during GH therapy and therefore support the translation of growth hormone as a therapeutic method to promote improved functional recovery in upper extremity transplantation.

Single-Use Negative Pressure Wound Therapy Applied on Various Wound Types: An Interventional Case Series.

PURPOSE: The purpose of this study was to determine whether a single-use negative pressure wound therapy (NPWT) system achieves individualized goals of therapy when used to treat patients with a variety of wound types. DESIGN: Multiple case series. SUBJECTS AND SETTING: The same comprised 25 participants; their mean age was 51.2 years (SD: 18.2; range: 19-79 years); 14 were male (56%) and 11 were female (44%). Seven study participants withdrew from study participation. Wound etiologies vary; 4 had diabetic foot ulcers; 1 had a full-thickness pressure injury; 7 were treated for management of an abscess or cyst; 4 had necrotizing fasciitis, 5 had nonhealing postsurgical wounds, and 4 had wounds of other etiologies. Data were collected at 2 ambulatory wound care clinics located in the Southeastern United States (Augusta and Austell, Georgia). METHODS: A single-outcome measure was selected for each participant by his or her attending physician at a baseline visit. Selected end points were (1) decrease in wound volume, (2) decrease in size of the tunneling area, (3) decrease in size of the undermining, (4) decrease in the amount of slough, (5) increase in granulation tissue formation, (6) decrease in periwound swelling, and (7) wound bed progression toward transition to another treatment modality (such as standard dressing, surgical closure, flap, or graft). Progress toward the individualized goal was monitored until the goal was achieved (study end point) or a maximum of 4 weeks following initiation of treatment. RESULTS: The most common primary treatment goal was to achieve a decrease in wound volume (22 of 25 study participants), and the goal to increase granulation tissue was chosen for the remaining 3 study participants. A majority of participants (18 of 23, 78.3%) reached their individualized treatment outcome. The remaining 5 participants (21.7%) were withdrawn during the study (for reasons not related to the therapy). The median (interquartile range [IQR]) duration of NPWT therapy was 19 days (IQR: 14-21 days). Between baseline and the final assessment, median reductions in wound area and volume were 42.7% (IQR: 25.7-71.5) and 87.5% (IQR: 30.7-94.6). CONCLUSIONS: The single-use NPWT system achieved multiple individualized treatment objectives in a variety of wound types. Individually selected goals of therapy were met by all study participants who completed the study.

Regionalization of Head and Neck Oncology Tumor Boards: Perspectives of Collaborating Physicians.

Objectives: To survey academic and community physician preferences regarding the virtual multidisciplinary tumor board (MTB) for further improvement and expansion. Study Design: This anonymous 14-question survey was sent to individuals that participated in the head and neck virtual MTBs. The survey was sent via email beginning August 3, 2021, through October 5, 2021. Setting: The University of Maryland Medical Center and regional practices in the state of Maryland. Methods: Survey responses were recorded and presented as percentages. Subset analysis was performed to obtain frequency distributions by facility and provider type. Results: There were 50 survey responses obtained with a response rate of 56%. Survey participants included 11 surgeons (22%), 19 radiation oncologists (38%), and 8 medical oncologists (16%), amongst others. More than 96% of participants found the virtual MTB to be useful when discussing complex cases and impactful to future patient care. A majority of respondents perceived a reduction in time to adjuvant care (64%). Community and academic physician responses strongly agreed that the virtual MTB improved communication (82% vs 73%), provided patient-specific information for cancer care (82% vs 73%), and improved access to other specialties (66% vs 64%). Academic physicians, more so than community physicians, strongly agreed that the virtual MTB improves access to clinical trial enrollment (64% vs 29%) and can be useful in obtaining CME (64% vs 55%). Conclusion: Academic and community physicians view the virtual MTB favorably. This platform can be adapted regionally and further expanded to improve communication between physicians and improve multidisciplinary care for patients.

MEK Inhibition Synergizes with TYK2 Inhibitors in NF1-Associated Malignant Peripheral Nerve Sheath Tumors.

PURPOSE: Malignant peripheral nerve sheath tumors (MPNST) are aggressive sarcomas with limited treatment options and poor survival rates. About half of MPNST cases are associated with the neurofibromatosis type 1 (NF1) cancer predisposition syndrome. Overexpression of TYK2 occurs in the majority of MPNST, implicating TYK2 as a therapeutic target. EXPERIMENTAL DESIGN: The effects of pharmacologic TYK2 inhibition on MPNST cell proliferation and survival were examined using IncuCyte live cell assays in vitro, and downstream actions were analyzed using RNA-sequencing (RNA-seq), qPCR arrays, and validation of protein changes with the WES automated Western system. Inhibition of TYK2 alone and in combination with MEK inhibition was evaluated in vivo using both murine and human MPNST cell lines, as well as MPNST PDX. RESULTS: Pharmacologic inhibition of TYK2 dose-dependently decreased proliferation and induced apoptosis over time. RNA-seq pathway analysis on TYK2 inhibitor-treated MPNST demonstrated decreased expression of cell cycle, mitotic, and glycolysis pathways. TYK2 inhibition resulted in upregulation of the MEK/ERK pathway gene expression, by both RNA-seq and qPCR array, as well as increased pERK1/2 levels by the WES Western system. The compensatory response was tested with dual treatment with TYK2 and MEK inhibitors, which synergistically decreased proliferation and increased apoptosis in vitro. Finally, combination therapy was shown to inhibit growth of MPNST in multiple in vivo models. CONCLUSIONS: These data provide the preclinical rationale for the development of a phase I clinical trial of deucravacitinib and mirdametinib in NF1-assosciated MPNST.

Yoga Therapy During Chemotherapy for Early-Stage and Locally Advanced Breast Cancer.

BACKGROUND: Chemotherapy is associated with decreased quality of life (QOL), fatigue, depression, and weight gain in patients with breast cancer. Weight gain is associated with poorer prognosis. Yoga improves QOL, fatigue, and mood in women with breast cancer but its effect on treatment-related weight gain has not been studied. The aim of this trial was to determine the feasibility of personalized yoga therapy in women receiving treatment for early-stage or locally advanced breast cancer and assess its impact on weight gain. METHODS: Thirty women were randomized 1:1 to receive yoga therapy by a certified yoga therapist during treatment or a control group. Participants in the yoga arm were asked to complete three 30 minute yoga sessions weekly (which included movement, breath work, mindfulness, and relaxation) throughout adjuvant or neoadjuvant chemotherapy (N = 29) or endocrine (N = 1); the control arm received breast cancer treatment without yoga. For comparability between participants randomized to yoga therapy, the single patient treated with endocrine therapy was excluded from the analysis. Primary outcomes were feasibility and weight change. Additional outcomes were mood, fatigue, QOL, serum tumor necrosis factor-alpha (TNF-alpha), and C-reactive protein (CRP) as immune mediator biomarkers. RESULTS: Mean age was 51.6 years, 75.9% were white and 24.1% were people of color, reflecting the cancer center population. 80% had stage II-III disease. Enrollment was completed in 9 months. Compliance was lower than predicted; however, participants participated in on average 1.7 yoga sessions/week for a mean 15.6 weeks duration. There were no adverse events. Control arm participants gained on average 2.63% body weight during treatment while yoga participants lost 0.14% body weight (weight change = -0.36 in yoga arm vs. 2.89 in standard of care arm, Wilcoxon rank sum test P = .024). Control participants reported increased fatigue and decreased QOL, while yoga participants reported no change in QOL. No significant change in TNF-alpha or CRP was noted in either arm. CONCLUSION: This feasibility study suggests that personalized yoga therapy is beneficial for QOL and weight maintenance among women undergoing chemotherapy for early-stage or locally advanced breast cancer. Weight maintenance associated with yoga therapy may be of clinical significance in this population given the poorer prognosis associated with weight gain in breast cancer survivors.

Human Papillomavirus Impact on Temporal Treatment Trends in Oropharyngeal Carcinoma: 2010-2016.

INTRODUCTION: The study objective was to identify practice patterns in oropharyngeal cancer management from 2010 to 2016 among human papillomavirus (HPV)-associated and non-HPV-associated oropharyngeal squamous-cell carcinoma (OPSCC) patients. METHODS: The National Cancer Database was utilized to identify OPSCC patients from 2010 to 2016. Frequency distributions and multivariable analyses were generated to identify practice patterns and predictors of treatment modality. RESULTS: A total of 35,956 patients with nonmetastatic OPSCC were included. HPV status was not associated with a treatment modality preference. At academic centers, the proportion of HPV-associated OPSCC patients versus non-HPV-associated OPSCC patients undergoing surgical management was similar (35.7%; 35.9%). Community cancer programs treated patients less often surgically but with no significant treatment preference based on HPV status. Within each facility type, HPV status was not a predictor of surgical or nonsurgical management. CONCLUSION: HPV association does not appear to significantly influence treatment modality preference among OPSCC patients. The proportion of OPSCC patients undergoing surgical treatment declined from 2010 to 2016.

Nivolumab plus rucaparib for metastatic castration-resistant prostate cancer: results from the phase 2 CheckMate 9KD trial.

BACKGROUND: CheckMate 9KD (NCT03338790) is a non-randomized, multicohort, phase 2 trial of nivolumab plus other anticancer treatments for metastatic castration-resistant prostate cancer (mCRPC). We report results from cohorts A1 and A2 of CheckMate 9KD, specifically evaluating nivolumab plus rucaparib. METHODS: CheckMate 9KD enrolled adult patients with histologically confirmed mCRPC, ongoing androgen deprivation therapy, and an Eastern Cooperative Oncology Group performance status of 0-1. Cohort A1 included patients with postchemotherapy mCRPC (1-2 prior taxane-based regimens) and ≤2 prior novel hormonal therapies (eg, abiraterone, enzalutamide, apalutamide); cohort A2 included patients with chemotherapy-naïve mCRPC and prior novel hormonal therapy. Patients received nivolumab 480 mg every 4 weeks plus rucaparib 600 mg two times per day (nivolumab dosing ≤2 years). Coprimary endpoints were objective response rate (ORR) per Prostate Cancer Clinical Trials Working Group 3 and prostate-specific antigen response rate (PSA50-RR; ≥50% PSA reduction) in all-treated patients and patients with homologous recombination deficiency (HRD)-positive tumors, determined before enrollment. Secondary endpoints included radiographic progression-free survival (rPFS), overall survival (OS), and safety. RESULTS: Outcomes (95% CI) among all-treated, HRD-positive, and BRCA1/2-positive populations for cohort A1 were confirmed ORR: 10.3% (3.9-21.2) (n=58), 17.2% (5.8-35.8) (n=29), and 33.3% (7.5-70.1) (n=9); confirmed PSA50-RR: 11.9% (5.9-20.8) (n=84), 18.2% (8.2-32.7) (n=44), and 41.7% (15.2-72.3) (n=12); median rPFS: 4.9 (3.7-5.7) (n=88), 5.8 (3.7-8.4) (n=45), and 5.6 (2.8-15.7) (n=12) months; and median OS: 13.9 (10.4-15.8) (n=88), 15.4 (11.4-18.2) (n=45), and 15.2 (3.0-not estimable) (n=12) months. For cohort A2 they were confirmed ORR: 15.4% (5.9-30.5) (n=39), 25.0% (8.7-49.1) (n=20), and 33.3% (7.5-70.1) (n=9); confirmed PSA50-RR: 27.3% (17.0-39.6) (n=66), 41.9 (24.5-60.9) (n=31), and 84.6% (54.6-98.1) (n=13); median rPFS: 8.1 (5.6-10.9) (n=71), 10.9 (6.7-12.0) (n=34), and 10.9 (5.6-12.0) (n=15) months; and median OS: 20.2 (14.1-22.8) (n=71), 22.7 (14.1-not estimable) (n=34), and 20.2 (11.1-not estimable) (n=15) months. In cohorts A1 and A2, respectively, the most common any-grade and grade 3-4 treatment-related adverse events (TRAEs) were nausea (40.9% and 40.8%) and anemia (20.5% and 14.1%). Discontinuation rates due to TRAEs were 27.3% and 23.9%, respectively. CONCLUSIONS: Nivolumab plus rucaparib is active in patients with HRD-positive postchemotherapy or chemotherapy-naïve mCRPC, particularly those harboring BRCA1/2 mutations. Safety was as expected, with no new signals identified. Whether the addition of nivolumab incrementally improves outcomes versus rucaparib alone cannot be determined from this trial. TRIAL REGISTRATION NUMBER: NCT03338790.

Tumor Histological Grade and Immunotherapy Response in Patients With Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma.

Importance: Tumor histological factors that predict immunotherapy response in patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) are not well defined. Objective: To investigate the association between tumor grade and immunotherapy response in patients with recurrent or metastatic mucosal HNSCC. Design, Setting, and Participants: In this retrospective cohort study, the medical records of 60 patients with recurrent or metastatic mucosal HNSCC treated with immune checkpoint inhibitors at Johns Hopkins Hospital between July 1, 2015, and January 22, 2020, were reviewed. Exposures: High-grade tumors (HGTs) vs low-grade tumors (LGTs) in recurrent or metastatic HNSCC. Main Outcomes and Measures: Patients were divided into 2 groups: those with LGTs (well differentiated and moderately differentiated) and those with HGTs (poorly differentiated). The main outcome was a clinically beneficial immunotherapy response, defined as complete response or partial response. Univariable and multivariable logistic regressions were conducted to calculate odds ratios for each variable's association with immunotherapy response. Survival differences were evaluated using Kaplan-Meier survival curves with multivariable Cox proportional hazards regression models. Results: The 60 patients (35 with HGTs and 25 with LGTs) had a mean (SD) age of 64.6 (8.88) years; 51 were male (85%); and 38 were current or former smokers (63%). The oropharynx was the most common primary tumor site both in patients with HGTs (22 of 35; 63%) and those with LGTs (12 of 25; 48%). Bivariate analysis showed the proportion of patients having a beneficial response to immunotherapy was greater for patients with HGTs (12 of 35; 34.3%) than those with LGTs (2 of 25, 8.0%) (difference, 26.3%; 95% CI, 7.3%-45.3%). Upon multivariable analysis, patients with HGTs had 5.35-fold increased odds (95% CI, 1.04-27.37) of having a clinically beneficial response to immunotherapy. Among patients with available tumor genomic profiling data, the mean tumor mutational burden was greater for patients with HGTs (mean [SD], 8.6 [5.4] mut/Mb; n = 8) than patients with LGTs (mean [SD], 3.6 [1.1] mut/Mb; n = 4) (difference = 5.0 mut/Mb; 95% CI -1.4 to 11.4 mut/Mb; Cohen d = 1.2). Conclusions and Relevance: In this cohort study, tumor grade was independently associated with immunotherapy response in patients with recurrent or metastatic mucosal HNSCC. These findings highlight the potential role of tumor grade in predicting immunotherapy response in mucosal HNSCC.

Impact of the Novel Coronavirus 2019 (COVID-19) Pandemic on Head and Neck Cancer Care.

OBJECTIVE: The study aimed to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on head and neck oncologic care at a tertiary care facility. STUDY DESIGN: This was a cross-sectional study conducted between March 18, 2020, and May 20, 2020. The primary planned outcome was the rate of treatment modifications during the study period. Secondary outcome measures were tumor conference volume, operative volume, and outpatient patient procedure and clinic volumes. SETTING: This single-center study was conducted at a tertiary care academic hospital in a large metropolitan area. METHODS: The study included a consecutive sample of adult subjects who were presented at a head and neck interdepartmental tumor conference during the study period. Patients were compared to historical controls based on review of operative data, outpatient procedures, and clinic volumes. RESULTS: In total, 117 patients were presented during the review period in 2020, compared to 69 in 2019. There was an 8.4% treatment modification rate among cases presented at the tumor conference. There was a 61.3% (347 from 898) reduction in outpatient clinic visits and a 63.4% (84 from 230) reduction in procedural volume compared to the prior year. Similarly, the operative volume decreased by 27.0% (224 from 307) compared to the previous year. CONCLUSION: Restrictions related to the COVID-19 pandemic resulted in limited treatment modifications. Transition to virtual tumor board format observed an increase in case presentations. While there were reductions in operative volume, there was a larger proportion of surgical cases for malignancy, reflecting the prioritization of oncologic care during the pandemic.

Nivolumab plus docetaxel in patients with chemotherapy-naïve metastatic castration-resistant prostate cancer: results from the phase II CheckMate 9KD trial.

BACKGROUND: Docetaxel has immunostimulatory effects that may promote an immunoresponsive prostate tumour microenvironment, providing a rationale for combination with nivolumab (programmed death-1 inhibitor) for metastatic castration-resistant prostate cancer (mCRPC). METHODS: In the non-randomised, multicohort, global phase II CheckMate 9KD trial, 84 patients with chemotherapy-naive mCRPC, ongoing androgen deprivation therapy and ≤2 prior novel hormonal therapies (NHTs) received nivolumab 360 mg and docetaxel 75 mg/m2 every 3 weeks with prednisone 5 mg twice daily (≤10 cycles) and then nivolumab 480 mg every 4 weeks (≤2 years). The co-primary end-points were objective response rate (ORR) and prostate-specific antigen response rate (PSA50-RR; ≥50% decrease from baseline). RESULTS: The confirmed ORR (95% confidence interval [CI]) was 40.0% (25.7-55.7), and the confirmed PSA50-RR (95% CI) was 46.9% (35.7-58.3). The median (95% CI) radiographic progression-free survival (rPFS) and overall survival (OS) were 9.0 (8.0-11.6) and 18.2 (14.6-20.7) months, respectively. In subpopulations with versus without prior NHT, the ORR was 38.7% versus 42.9%, the PSA50-RR was 39.6% versus 60.7%, the median rPFS was 8.5 versus 12.0 months and the median OS was 16.2 months versus not reached. Homologous recombination deficiency status or tumour mutational burden did not appear to impact efficacy. The most common any-grade and grade 3-4 treatment-related adverse events were fatigue (39.3%) and neutropenia (16.7%), respectively. Three treatment-related deaths occurred (1 pneumonitis related to nivolumab; 2 pneumonias related to docetaxel). CONCLUSIONS: Nivolumab plus docetaxel has clinical activity in patients with chemotherapy-naïve mCRPC. Safety was consistent with the individual components. These results support further investigation in the ongoing phase III CheckMate 7DX trial. CLINICALTRIALS. GOV REGISTRATION: NCT03338790.

Neoadjuvant immunotherapy prior to surgery for mucosal head and neck squamous cell carcinoma: Systematic review.

Given the recent successes of anti-PD-1 immunotherapy, many clinical trials have sought to assess the safety and efficacy of this treatment modality in the neoadjuvant setting. This systematic review provides a comprehensive summary of findings from neoadjuvant head and neck cancer immunotherapy clinical trials with a focus on PD-1/PD-L1 axis blockade. Pubmed, Embase, Cochrane Library, Web of Science, Google Scholar, and clinicaltrials.gov were systematically searched for all eligible neoadjuvant head and neck cancer immunotherapy clinical trials. Eight clinical trials met the inclusion criteria comprising a total of 260 patients. Study drugs included nivolumab, pembrolizumab, ipilimumab, durvalumab, and tremelimumab. The overall mean objective response rate (ORR) was 45.9 ± 5.7% with a 41.5 ± 5.6% single agent mean ORR. There were no deaths due to immune-related toxicities. Neoadjuvant immunotherapy for mucosal head and neck squamous cell cancer has demonstrated favorable response rates with no unexpected immune-related toxicities in phase I/II clinical trials.

Association of Tumor Site With the Prognosis and Immunogenomic Landscape of Human Papillomavirus-Related Head and Neck and Cervical Cancers.

Importance: Human papillomavirus (HPV)-positive status in patients with oropharyngeal squamous cell carcinoma (OPSCC) is associated with improved survival compared with HPV-negative status. However, it remains controversial whether HPV is associated with improved survival among patients with nonoropharyngeal and cervical squamous cell tumors. Objective: To investigate differences in the immunogenomic landscapes of HPV-associated tumors across anatomical sites (the head and neck and the cervix) and their association with survival. Design, Setting, and Participants: This cohort study used genomic and transcriptomic data from the Cancer Genome Atlas (TCGA) for 79 patients with OPSCC, 435 with nonoropharyngeal head and neck squamous cell carcinoma (non-OP HNSCC), and 254 with cervical squamous cell carcinoma and/or endocervical adenocarcinoma (CESC) along with matched clinical data from TCGA. The data were analyzed from November 2020 to March 2021. Main Outcomes and Measures: Positivity for HPV was classified by RNA-sequencing reads aligned with the HPV reference genome. Gene expression profiles, immune cell phenotypes, cytolytic activity scores, and overall survival were compared by HPV tumor status across multiple anatomical sites. Results: The study comprised 768 patients, including 514 (66.9%) with HNSCC (380 male [73.9%]; mean [SD] age, 59.5 [10.8] years) and 254 (33.1%) with CESC (mean [SD] age, 48.7 [14.1] years). Human papillomavirus positivity was associated with a statistically significant improvement in overall survival for patients with OPSCC (adjusted hazard ratio [aHR], 0.06; 95% CI, 0.02-0.17; P < .001) but not for those with non-OP HNSCC (aHR, 0.64; 95% CI, 0.31-1.27; P = .20) or CESC (aHR, 0.50; 95% CI, 0.15-1.67; P = .30). The HPV-positive OPSCCs had increased tumor immune infiltration and immunomodulatory receptor expression compared with HPV-negative OPSCCs. Compared with HPV-positive non-OP HNSCCs, HPV-positive OPSCCs showed greater expression of immune-related metrics including B cells, T cells, CD8+ T cells, T-cell receptor diversity, B-cell receptor diversity, and cytolytic activity scores, independent of tumor variant burden. The immune-related metrics were similar when comparing HPV-positive non-OP HNSCCs and HPV-positive CESCs with their HPV-negative counterparts. The 2-year overall survival rate was significantly higher for patients with HPV-positive OPSCC compared with patients with HPV-negative OPSCC (92.0% [95% CI, 84.8%-99.9%] vs 45.8% [95% CI, 28.3%-74.1%]; HR, 0.10 [95% CI, 0.03-0.30]; P = .009). Conclusions and Relevance: In this cohort study, tumor site was associated with the immune landscape and survival among patients with HPV-related tumors despite presumed similar biologic characteristics. These tumor site-related findings provide insight on possible outcomes of HPV positivity for tumors in oropharyngeal and nonoropharyngeal sites and a rationale for the stratification of HPV-associated tumors by site and the subsequent development of strategies targeting immune exclusion in HPV-positive nonoropharyngeal cancer.

Nutritional Status as a Predictive Biomarker for Immunotherapy Outcomes in Advanced Head and Neck Cancer.

The association between pretreatment nutritional status and immunotherapy response in patients with advanced head and neck cancer is unclear. We retrospectively analyzed a cohort of 99 patients who underwent treatment with anti-PD-1 or anti-CTLA-4 antibodies (or both) for stage IV HNSCC between 2014 and 2020 at the Johns Hopkins Hospital. Patient demographics and clinical characteristics were retrieved from electronic medical records. Baseline prognostic nutritional index (PNI) scores and pretreatment body mass index (BMI) trends were calculated. Associations between PNI and BMI were correlated with overall survival (OS), progression-free survival (PFS), and immunotherapy response. In univariate analysis, there was a significant correlation between OS and PFS with baseline PNI (OS: HR: 0.464; 95% CI: 0.265-0.814; PFS: p = 0.007 and HR: 0.525; 95% CI: 0.341-0.808; p = 0.003). Poor OS was also associated with a greater decrease in pretreatment BMI trend (HR: 0.42; 95% CI: 0.229-0.77; p = 0.005). In multivariate analysis, baseline PNI but not BMI trend was significantly associated with OS and PFS (OS: log (HR) = -0.79, CI: -1.6, -0.03, p = 0.041; PFS: log (HR) = -0.78, CI: -1.4, -0.18, p = 0.011). In conclusion, poor pretreatment nutritional status is associated with negative post-immunotherapy outcomes.

TYK2 in Cancer Metastases: Genomic and Proteomic Discovery.

Advances in genomic analysis and proteomic tools have rapidly expanded identification of biomarkers and molecular targets important to cancer development and metastasis. On an individual basis, personalized medicine approaches allow better characterization of tumors and patient prognosis, leading to more targeted treatments by detection of specific gene mutations, overexpression, or activity. Genomic and proteomic screens by our lab and others have revealed tyrosine kinase 2 (TYK2) as an oncogene promoting progression and metastases of many types of carcinomas, sarcomas, and hematologic cancers. TYK2 is a Janus kinase (JAK) that acts as an intermediary between cytokine receptors and STAT transcription factors. TYK2 signals to stimulate proliferation and metastasis while inhibiting apoptosis of cancer cells. This review focuses on the growing evidence from genomic and proteomic screens, as well as molecular studies that link TYK2 to cancer prevalence, prognosis, and metastasis. In addition, pharmacological inhibition of TYK2 is currently used clinically for autoimmune diseases, and now provides promising treatment modalities as effective therapeutic agents against multiple types of cancer.

Long-term outcomes of a prospective randomized trial of 131Cs/125I permanent prostate brachytherapy.

PURPOSE: Iodine-125 (125I) is the most commonly used isotope for prostate brachytherapy (BT). Cesium-131 (131Cs) has a higher dose rate and shorter dose delivery time resulting in decreased duration of acute urinary morbidity. Long-term data suggest excellent oncologic outcomes; it is not known how outcomes compare. A prospective randomized trial comparing the two isotopes was initiated. MATERIALS AND METHODS: Patients with low- or intermediate-risk disease were treated with a BT in a single outpatient facility. Prescription dose was 144 Gy for 125I and 115 Gy for 131Cs. Androgen deprivation or supplemental EBRT was not allowed. The primary study objective was comparison of the mean EPIC Urinary Domain Score. Secondary objective was biochemical relapse-free survival (BRFS) comparison. Time-to-event for all outcomes of interest was measured from implant date. RESULTS: One hundred forty men were enrolled; 81.4% were low-risk and 18.6% were intermediate-risk. The median followup was 97 months. Urinary and sexual health-related quality of life did not differ between isotopes at any recorded time point. At 2 months after implantation, bowel health-related quality of life was worse with 125I; however, this difference was lost at subsequent time points. The 9-year BRFS was 87.2% and 84.0% for the 125I and 131Cs group, respectively (p = 0.897). There was no statistically significant difference in BRFS based on initial T stage, PSA, or Gleason score. CONCLUSIONS: Short- and long-term urinary, sexual, and bowel quality of life, as well as long-term biochemical control were comparable between 125I and 131Cs. This report therefore supports the continued use of 131Cs as an effective and comparable alternative isotope.

Patterns of Failure in Triple Negative Breast Cancer Patients in an Urban, Predominately Black Population.

Triple negative breast cancers (TNBC) behave more aggressively than hormone-receptor positive breast cancers. They are also known preferentially to affect young black women, often leading to poorer outcomes compared with those for white women. We sought to evaluate the comprehensive patterns of failure associated with treatment for TNBC at an urban institution with a predominantly black population and to assess the impact of social determinants of health on treatment failure. A retrospective review of TNBC patients treated from 2005 to 2015 was conducted. Detailed patient, tumor, and treatment characteristics and information on patterns of failure were included. With a median follow-up of 46 months, 32 (16%) documented failures occurred. Locoregional failures comprised 84% of failure patterns whether isolated or in combination with distant failure. Treatment failure was associated with insurance type and smoking status, as well as several tumor characteristics. On multivariate analysis, pathologic nodal staging was the most significant predictor of treatment failure. In contrast to previous studies, we found that black women had higher overall survival than white women, but race was not associated with differences in recurrence patterns or with likelihood of treatment failure. Regardless of race, of the patients who recurred, 53% failed in distant and locoregional sites simultaneously, with an additional 34% failing locally only. These results highlight the need for aggressive local therapies in high-risk patients and suggest a need for improved follow-up focusing on detecting locoregional failures. Multidisciplinary care is essential in the management of these patients at time of failure.

Incidental Coronary Artery Calcium on Breast Radiation Therapy Planning Scans Identifies Patients for Cardiac Preventive Therapy.

PURPOSE/OBJECTIVE(S): The presence of coronary artery calcium (CAC>0) is associated with increased cardiac-related mortality and is a common indication to initiate statin therapy to prevent future long-term cardiac-related adverse events. CAC is also well visualized on noncontrast chest computed tomography simulation (CT sim) scans used for breast radiation planning. We hypothesize that by screening for incidental CAC on CT sims, radiation oncologists could help identify patients who may benefit from additional preventive medical interventions with their primary care physician or cardiologist. METHODS: A retrospective analysis of 126 consecutive patients with breast cancer treated with external beam radiation therapy at a single institution was performed. Noncontrast CT sim scans were reviewed for the presence of CAC and the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) was calculated to identify patients who may benefit from initiating statin therapy. Patients with CAC>0 and/or ASCVD risk >20% were identified as those who may benefit from statin therapy. RESULTS: Out of 72 patients with CAC>0, only 12(16%) had reported pre-existing coronary artery disease and 32(44%) were not already on recommended statin therapy. CAC>0 visualized on CT sim was able to identify 29 additional patients who would benefit from statin beyond what the ASCVD risk calculator could identify. CONCLUSION: Observation of incidental CAC on breast radiation-planning CT scans identified patients who could benefit from cardiac-related preventive strategies. By increasing attention, awareness, and reporting of incidental CAC visible on CT sims, radiation oncologists may fulfill a unique role to bridge a potential gap in cardiovascular preventive medicine.
