Oropharyngeal squamous cell carcinoma (OPSCC) originating from human papillomavirus infection has emerged as a new entity in head and neck cancer, defining a subset of patients with distinct carcinogenesis, risk factor profiles, and clinical presentation that show markedly improved survival than patients with classic OPSCC. De-escalation of therapy and identification of relevant biomarkers to aid in patient selection are actively being investigated. This review addresses the implications of thes ...[more]

Project description:IntroductionDespite the human papillomavirus conferring a better prognosis in the primary treatment setting, the prognostic impact of viral status after treatment failure in oropharyngeal squamous cell carcinoma patients is poorly understood.MethodsWe retrospectively identified 33 oropharyngeal squamous cell carcinoma (OPC) patients with local and/or distant disease recurrence post-treatment, and looked at metastatic patterns, time to failure and survival patterns by HPV status.ResultsMedian overall survival following local failure was not significantly different by HPV status (17 months for HPV+ vs. 14 months for HPV-, p = 0.23). However, following distant failures, HPV+ patients lived significantly longer than HPV- patients (median 42 months vs. 11 months, p = 0.004). HPV- patients were more likely to have locoregional failures as compared to HPV+ patients (p = 0.005), but the difference in distant failure between both groups was not significant (p = 0.09). HPV+ patients were more likely to develop metastases to sites other than the lung and bones.ConclusionHPV positivity predicts a favorable prognosis with the potential for long-term survival following distant, not locoregional, failures. These results have important implications for the aggressiveness of treatment and type of surveillance imaging performed.

Project description:The population of survivors with human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) is rising. The improved prognosis of this etiologic subset is reflected in new staging guidelines as well as ongoing deintensification trials aiming to preserve excellent survival while decreasing treatment-related toxicities. However, as staging criteria and treatment standards evolve in the era of transoral surgery and deintensification, little is known regarding the needs and treatment preferences of patients with HPV-OPSCC. Herein, the current knowledge regarding treatment preferences and priorities, quality of life and concerns among patients with HPV-OPSCC is reviewed.

Project description:Current adjuvant treatment guidelines for oropharyngeal squamous cell carcinoma treated with primary surgery are based on studies that predate the human papillomavirus (HPV) era. HPV-associated oropharynx carcinoma (HPV-OPC) has a much more favorable prognosis compared to HPV-unassociated cancer and is increasingly considered to be a distinct disease entity due to its unique etiology, presentation, and behavior. Currently, there is significant interest in adjuvant treatment de-intensification of HPV-OPC patients in order to reduce treatment-related toxicity while maintaining excellent clinical outcomes. Here, we review the evidence and rationale underlying the ongoing prospective trials of adjuvant treatment de-intensification for HPV-OPC patients.

Project description:Background/Objective: The incidence of oropharyngeal cancer (OPC) remains significant, with a rising prevalence of HPV-positive (HPV+) cases, underscoring the growing importance of appropriate treatment approaches for this condition. While HPV+ OPC typically exhibits a more favorable prognosis than HPV-negative (HPV-) OPC, certain HPV+ OPC patients still face adverse outcomes. This study aimed to assess the effectiveness of TORS versus traditional surgery in treating OPC patients and investigate the prognostic implications of specific variants in the HPV genome. Methods: The clinical information, including pathological features, treatments, and outcomes (death), of 135 OPC patients treated with traditional surgery from 2008 to 2018 (the non-TORS group) and 130 OPC patients treated with TORS from 2017 to 2021 (the TORS group) were obtained from Sun Yat-sen University Cancer Center (SYSUCC). A comparative analysis of 3-year overall survival (OS) was performed between these two groups. Furthermore, we conducted next-generation sequencing for the HPV16 genome of the 68 HPV+ OPC cases to characterize single-nucleotide variations (SNVs) in the HPV16 genome and evaluate its association with HPV+ OPC patient survival. Results: The comparative analysis of 3-year OS between the two groups (TORS vs. non-TORS) revealed a significant prognostic improvement in the TORS group for OPC patients with a T1-T2 classification (89.3% vs. 72.0%; p = 1.1 × 10-2), stages I-II (92.1% vs. 82.2%; p = 4.6 × 10-2), and stages III-IV (82.8% vs. 62.2%; p = 5.7 × 10-2) and for HPV- patients (85.5% vs. 33.3%; p < 1.0 × 10-6). Furthermore, three SNVs (SNV1339A>G, SNV1950A>C, and SNV4298A>G) in the HPV16 genome were identified as being associated with worse survival. These SNVs could alter protein interactions and weaken the binding affinity for MHC-II, promoting viral amplification and immune evasion. Conclusions: TORS exhibited a superior prognosis to traditional surgery in OPC patients. Additionally, identifying specific SNVs within the HPV16 genome provided potential prognostic markers for HPV+ OPC. These significant findings hold clinical relevance for treatment decision-making and prognostic assessment in patients with OPC.

Project description:IntroductionLittle is known regarding how human papillomavirus-positive oropharyngeal cancer (HPV-OPC) patient goals change with treatment. This study evaluates whether patient ranking of non-oncologic priorities relative to cure and survival shift after treatment as compared to priorities at diagnosis.Materials and methodsThis is a prospective study of HPV-OPC patient survey responses at diagnosis and after treatment. The relative importance of 12 treatment-related priorities was ranked on an ordinal scale (1 as highest). Median rank (MR) was compared using Wilcoxon matched-pairs signed-rank tests. Prevalence of high concern for 11 treatment-related issues was compared using paired t-test. The effect of patient characteristics on change in priority rank and concern was evaluated using linear regression.ResultsAmong 37 patients, patient priorities were generally unchanged after treatment compared with at diagnosis, with cure and survival persistently ranked top priority. Having a moist mouth uniquely rose in importance after treatment. Patient characteristics largely did not affect change in priority rank. Concerns decreased after treatment, except concern regarding recurrence.DiscussionTreatment-related priorities are largely similar at diagnosis and after treatment regardless of patient characteristics. The treatment experience does not result in a shift of priorities from cure and survival to non-oncologic domains over cure and survival. The rise in importance of moist mouth implies that xerostomia may have been underappreciated as a sequelae of treatment. A decrease in most treatment-related concerns is encouraging, whereas the persistence of specific areas of concern may inform patient counseling.

Project description:In a European cohort, it was previously reported that 35% of oropharyngeal cancer (OPC) patients were human papillomavirus type-16 (HPV16) seropositive up to 10 years before diagnosis vs 0.6% of cancer-free controls. Here, we describe the kinetics of HPV16-E6 antibodies prior to OPC diagnosis. We used annual serial prediagnostic blood samples from the PLCO Cancer Screening Trial. Antibodies to HPV were initially assessed in prediagnostic blood drawn at study enrollment from 198 incident head and neck cancer patients (median years to cancer diagnosis = 6.6) and 924 matched control subjects using multiplex serology, and subsequently in serial samples (median = 5/individual). Available tumor samples were identified and tested for HPV16 RNA to define HPV-driven OPC. HPV16-E6 antibodies were present at baseline in 42.3% of 52 OPC patients and 0.5% of 924 control subjects. HPV16-E6 antibody levels were highly elevated and stable across serial blood samples for 21 OPC patients who were seropositive at baseline, as well as for one OPC patient who seroconverted closer to diagnosis. All five subjects with HPV16-driven OPC tumors were HPV16-E6-seropositive, and the four subjects with HPV16-negative OPC tumors were seronegative. The estimated 10-year cumulative risk of OPC was 6.2% (95% confidence interval [CI] = 1.8% to 21.5%) for HPV16-E6-seropositive men, 1.3% (95% CI = 0.1% to 15.3%) for HPV16-E6-seropositive women, and 0.04% (95% CI = 0.03% to 0.06%) among HPV16-E6-seronegative individuals. Forty-two percent of subjects diagnosed with OPC between 1994 and 2009 in a US cohort were HPV16-E6 seropositive, with stable antibody levels during annual follow-up for up to 13 years prior to diagnosis. Tumor analysis indicated that the sensitivity and specificity of HPV16-E6 antibodies were exceptionally high in predicting HPV-driven OPC.

Project description:The most common cancer caused by human papillomavirus (HPV) infection in the United States is oropharyngeal cancer (OPC), and its incidence has been rising since the turn of the century. Because of substantial long-term morbidities with chemoradiation and the favorable prognosis of HPV-positive OPC, identifying the optimal deintensification strategy for this group has been a keystone of academic head-and-neck surgery, radiation oncology, and medical oncology for over the past decade. However, the first generation of randomized chemotherapy deintensification trials failed to change the standard of care, triggering concern over the feasibility of de-escalation. National database studies estimate that up to one third of patients receive nonstandard de-escalated treatments, which have subspecialty-specific nuances. A synthesis of the multidisciplinary deintensification data and current treatment standards is important for the oncology community to reinforce best practices and ensure optimal patient outcomes. In this review, the authors present a summary and comparison of prospective HPV-positive OPC de-escalation trials. Chemotherapy attenuation compromises outcomes without reducing toxicity. Limited data comparing transoral robotic surgery (TORS) with radiation raise concern over toxicity and outcomes with TORS. There are promising data to support de-escalating adjuvant therapy after TORS, but consensus on treatment indications is needed. Encouraging radiation deintensification strategies have been reported (upfront dose reduction and induction chemotherapy-based patient selection), but level I evidence is years away. Ultimately, stage and HPV status may be insufficient to guide de-escalation. The future of deintensification may lie in incorporating intratreatment response assessments to harness the powers of personalized medicine and integrate real-time surveillance.

Project description:Human papillomavirus (HPV)-related oropharyngeal squamous cell cancer (OPSCC) has emerged as a distinct clinical entity of head and neck cancer with expected high survival. This recognition has led to the investigation of whether a population of patients can be identified who can safely undergo treatment de-escalation, in an effort to minimize long-term treatment toxicity while maintaining excellent survival. The purpose of this review is to describe the rationale for treatment deintensification for HPV-related OPSCC, summarize available results from published clinical trials, explore the methods by which risk groups are assigned, and provide context for the multitude of clinical trials that are currently underway.

Project description:BackgroundNew ultrasensitive methods for detecting residual disease after surgery are needed in human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV+OPSCC).MethodsTo determine whether the clearance kinetics of circulating tumor human papillomavirus DNA (ctHPVDNA) is associated with postoperative disease status, a prospective observational study was conducted in 33 patients with HPV+OPSCC undergoing surgery. Blood was collected before surgery, postoperative days 1 (POD 1), 7, and 30 and with follow-up. A subcohort of 12 patients underwent frequent blood collections in the first 24 hours after surgery to define early clearance kinetics. Plasma was run on custom droplet digital polymerase chain reaction (ddPCR) assays for HPV genotypes 16, 18, 33, 35, and 45.ResultsIn patients without pathologic risk factors for recurrence who were observed after surgery, ctHPVDNA rapidly decreased to <1 copy/mL by POD 1 (n = 8/8). In patients with risk factors for macroscopic residual disease, ctHPVDNA was markedly elevated on POD 1 (>350 copies/mL) and remained elevated until adjuvant treatment (n = 3/3). Patients with intermediate POD 1 ctHPVDNA levels (1.2-58.4 copies/mL) all possessed pathologic risk factors for microscopic residual disease (n = 9/9). POD 1 ctHPVDNA levels were higher in patients with known adverse pathologic risk factors such as extranodal extension >1 mm (P = .0481) and with increasing lymph nodes involved (P = .0453) and were further associated with adjuvant treatment received (P = .0076). One of 33 patients had a recurrence that was detected by ctHPVDNA 2 months earlier than clinical detection.ConclusionsPOD 1 ctHPVDNA levels are associated with the risk of residual disease in patients with HPV+OPSCC undergoing curative intent surgery and thus could be used as a personalized biomarker for selecting adjuvant treatment in the future.Lay summaryHuman papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV+OPSCC) is increasing at epidemic proportions and is commonly treated with surgery. This report describes results from a study examining the clearance kinetics of circulating tumor HPV DNA (circulating tumor human papillomavirus DNA [ctHPVDNA]) following surgical treatment of HPV+OPSCC. We found that ctHPVDNA levels 1 day after surgery are associated with the risk of residual disease in patients with HPV+OPSCC and thus could be used as a personalized biomarker for selecting adjuvant treatment in the future. These findings are the first to demonstrate the potential utility of ctHPVDNA in patients with HPV+OPSCC undergoing surgery.

Project description:BackgroundOropharyngeal squamous-cell carcinomas caused by human papillomavirus (HPV) are associated with favorable survival, but the independent prognostic significance of tumor HPV status remains unknown.MethodsWe performed a retrospective analysis of the association between tumor HPV status and survival among patients with stage III or IV oropharyngeal squamous-cell carcinoma who were enrolled in a randomized trial comparing accelerated-fractionation radiotherapy (with acceleration by means of concomitant boost radiotherapy) with standard-fractionation radiotherapy, each combined with cisplatin therapy, in patients with squamous-cell carcinoma of the head and neck. Proportional-hazards models were used to compare the risk of death among patients with HPV-positive cancer and those with HPV-negative cancer.ResultsThe median follow-up period was 4.8 years. The 3-year rate of overall survival was similar in the group receiving accelerated-fractionation radiotherapy and the group receiving standard-fractionation radiotherapy (70.3% vs. 64.3%; P=0.18; hazard ratio for death with accelerated-fractionation radiotherapy, 0.90; 95% confidence interval [CI], 0.72 to 1.13), as were the rates of high-grade acute and late toxic events. A total of 63.8% of patients with oropharyngeal cancer (206 of 323) had HPV-positive tumors; these patients had better 3-year rates of overall survival (82.4%, vs. 57.1% among patients with HPV-negative tumors; P<0.001 by the log-rank test) and, after adjustment for age, race, tumor and nodal stage, tobacco exposure, and treatment assignment, had a 58% reduction in the risk of death (hazard ratio, 0.42; 95% CI, 0.27 to 0.66). The risk of death significantly increased with each additional pack-year of tobacco smoking. Using recursive-partitioning analysis, we classified our patients as having a low, intermediate, or high risk of death on the basis of four factors: HPV status, pack-years of tobacco smoking, tumor stage, and nodal stage.ConclusionsTumor HPV status is a strong and independent prognostic factor for survival among patients with oropharyngeal cancer.
