Prognostic value of radiographically defined extranodal extension in human papillomavirus-associated locally advanced oropharyngeal carcinoma.

ABSTRACT:

Background

Pathologic extranodal extension (ENE) has traditionally guided the management of head and neck cancers. The prognostic value of radiographic ENE (rENE) in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (HPV + OPX) is uncertain.

Methods

Patients with HPV + OPX with adequate pretreatment radiographic nodal evaluation from a single institution were analyzed. rENE status was determined by neuroradiologists' at time of diagnosis. Distant metastasis-free survival (DMFS), overall survival (OS), and locoregional recurrence-free survival (LRFS) were estimated using Kaplan-Meier methods. Cox proportional hazards models were fit to assess the impact of rENE on survival endpoints.

Results

Hundred sixty-eight patients with OPX + squamous cell carcinomas diagnosed between April 2008 and December 2014 were included for analysis with median follow-up of 3.3 years. Eighty-eight percent of patients received concurrent chemoradiotherapy. rENE was not prognostic; its presence in patients with HPV + OPX did not significantly impact OS, LRFS, or DMFS.

Conclusions

In patients with HPV + OPX, rENE was not significantly associated with OS, LRFS, or DMFS.

Project description:ImportanceExtranodal extension (ENE) is an adverse feature in human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) and is an indication for adjuvant treatment escalation. Preoperative core needle biopsy (CNB) may cause lymph node capsule disruption related to ENE development; however, evidence regarding this association in OPSCC is lacking.ObjectiveTo assess whether preoperative nodal CNB is associated with presence of ENE in final pathology findings among patients with HPV-associated OPSCC targeted for primary surgical resection.Design, setting, and participantsThis retrospective cohort study was conducted at a single academic tertiary care center from 2012 to 2022. All patients with OPSCC treated with transoral robotic surgery were assessed for eligibility, and primary surgical patients with HPV-associated OPSCC and node-positive disease confirmed on neck dissection were included in analyses. Data were analyzed from November 28, 2022, to May 21, 2023.ExposurePreoperative nodal CNB.Main outcomes and measuresThe primary outcome was presence of ENE in final pathology findings. Secondary outcomes included adjuvant chemotherapy and recurrence rates. Outcomes of interest were investigated against patient demographic, clinical, and pathologic features.ResultsOf 106 patients (mean [SD] age, 60.2 [10.9] years; 99 [93.4%] men) included in analyses, 23 patients (21.7%) underwent CNB. Mean (range) preoperative node size was 3.0 (0.9-6.0) cm. Pathologic node class was pN1 in 97 patients (91.5%) and pN2 in 9 patients (8.5%). A total of 49 patients (46.2%) had ENE identified in final pathology analysis. Of 94 patients who received adjuvant therapy, 58 (61.7%) underwent radiation therapy and 36 (38.3%) underwent chemoradiation therapy. There were 9 recurrences (8.5%). In univariate analysis, CNB was associated with ENE (odds ratio [OR], 2.70; 95% CI, 1.03-7.08), but there was no association in a multivariable model including pN class and preoperative node size (OR, 2.56; 95% CI, 0.97-7.27). Compared with pN1 class, pN2 class was associated with ENE (OR, 10.93; 95% CI, 1.32-90.80). There were no associations of ENE with preoperative node size, presence of cystic or necrotic nodes, fine needle aspiration, tobacco or alcohol exposure, pathologic T class, prior radiation, or age. Furthermore, use of CNB was not associated with macroscopic ENE, adjuvant chemotherapy, or recurrence.Conclusions and relevanceThis cohort study of patients with HPV-associated OPSCC found that preoperative nodal CNB was strongly associated with ENE in final pathology, supporting the possibility of an artifactual ENE component in this population.
