Long-term functional swallowing and speech outcomes after transoral robotic surgery for oropharyngeal cancer.

ABSTRACT:

Objectives

Transoral robotic surgery (TORS) has emerged as a minimally invasive approach for oropharyngeal cancer, aiming to improve functional preservation and reduce morbidity. However, the long-term effects on speech and swallowing, crucial aspects of quality of life, remain unclear. This study investigates the long-term functional swallowing and speech outcomes of TORS for oropharyngeal cancer.

Methods

We retrospectively reviewed 41 patients diagnosed with oropharyngeal squamous cell carcinoma who underwent TORS from 2010 to 2018. Tongue mobility, articulation, verbal diadochokinesis, reading speed, and modified barium swallowing tests were performed 2-3 years post-operatively to assess long-term speech and swallowing function.

Results

The mean age was 57.7 ± 9.9 years, and the male to female ratio was 34:7. The palatine tonsil was the most common tumor site (73.2%), followed by the base of tongue (22.0%). Concurrent neck dissection was performed in 97.6% of patients, and adjuvant radiation or chemoradiation was administered to 36 patients (87.8%). Tongue mobility, articulation, verbal diadochokinesis, and reading speed were comparable to normal population. Modified barium swallowing tests revealed acceptable outcomes in most patients; only one patient (2.4%) required a percutaneous endoscopic gastrostomy tube. Notably, no permanent tracheostomies were necessary.

Conclusions

Long-term speech and swallowing functions were preserved in most patients treated with TORS for oropharyngeal cancer. TORS is an excellent treatment modality for oropharyngeal cancer in terms of functional outcomes.

Project description:ImportanceIn recent years, transoral robotic surgery (TORS) has emerged as a useful treatment for oropharyngeal squamous cell carcinoma (OPSCC). In appropriately selected patients, the use of TORS may allow avoidance of adjuvant chemotherapy and/or radiotherapy, thereby avoiding the long-term adverse effects of these therapies.ObjectiveTo compare functional speech, swallowing, and quality-of-life outcomes longitudinally between those undergoing TORS only and those undergoing TORS and adjuvant radiotherapy (TORS+RT) or TORS and chemoradiotherapy (TORS+CRT).Design, setting, and participantsThis prospective, longitudinal cohort study performed from June 1, 2013, through November 31, 2015, included 74 patients undergoing TORS for initial treatment of OPSCC at a single tertiary academic hospital.Main outcomes and measuresData were collected at baseline, postoperatively (7-21 days), at short-term follow-up (6-12 months), and at long-term follow-up (>12 months). The quality-of-life metrics included the 10-item Eating Assessment Tool and the University of Michigan Head and Neck Quality of Life instrument. Data were also collected on tumor staging, surgical and adjuvant therapy details, patient comorbidities, tracheostomy and feeding tube use, and functional speech and swallowing status using the Performance Status Scale for Head and Neck Cancer Patients.ResultsSeventy-four patients were enrolled in the study (mean [SD] age, 61.39 [7.99] years; 68 [92%] male). Median long-term follow-up was 21 months (range, 12-36 months). The response rates were 86% (n = 64) postoperatively, 88% (n = 65) at short-term follow-up, and 86% (n = 64) at long-term follow-up. In all 3 groups, there was a significant worsening in pain and all swallowing-related measures postoperatively. There was subsequent improvement over time, with different trajectories observed across the 3 intervention groups. Postoperative dysphagia improved significantly more quickly in the TORS-only group. At long-term follow-up, weight loss differed between the TORS-only and TORS+RT groups (mean difference, -16.1; 97.5% CI, -29.8 to -2.4) and the TORS-only and TORS+CRT groups (mean difference, -14.6; 97.5% CI, -29.2 to 0) in a clinically meaningful way. In addition, the TORS-only group had significantly better scores than the TORS+CRT group on the Performance Status Scale-Eating in Public scale (mean difference, 21.8; 97.5% CI, 4.3-39.2) and Head and Neck Quality of Life-Eating scale (mean difference, 21.2; 97.5% CI, 4.0-38.3).Conclusions and relevancePatients who underwent TORS+CRT demonstrated poorer long-term outcomes, with continued dysphagia more than 1 year after surgery. These findings support the investigation of adjuvant de-escalation therapies to reduce the long-term adverse effects of treatment.

Project description:ImportanceThe treatment of oropharyngeal cancer has undergone a paradigm shift in the past 2 decades, with an increase in the use of nonoperative treatment owing to poor functional outcomes associated with traditional surgical approaches. Transoral robotic surgery (TORS) allows surgical resection of oropharyngeal cancer (OPC) with less morbidity through a minimally invasive approach.ObjectiveTo investigate the relationship among TORS and short- and long-term outcomes and costs in surgically treated patients with OPC.Design, setting, and participantsRetrospective cross-sectional analysis of 3573 patients who underwent an ablative procedure for OPC in 2010 to 2012 using the MarketScan Commercial Claim and Encounters database.Main outcomes and measuresThe association between TORS and short- and long-term outcomes, length of hospitalization, and treatment-related costs was analyzed using descriptive statistics and multivariate regression modeling.ResultsTransoral robotic surgery was performed in 304 surgical cases (8.5%); 94.7% of patients were 40 to 64 years old, and 70.7% were male. The use of TORS increased from 4.1% of surgical cases in 2010 to 13.2% of surgical cases in 2012. Patients who underwent TORS had a lower rate of tracheotomy during treatment (3.9% vs 11.4%), and posttreatment gastrostomy tube use (21.9% vs 34.2%), compared with patients undergoing non-TORS procedures. On multivariate analysis, TORS was not associated with significant differences in postoperative complications or length of hospitalization. There was no significant difference in the odds of receiving postoperative radiation therapy between patients who underwent TORS and those who did not; however, among patients receiving radiation therapy, chemoradiation was significantly less likely following TORS (odds ratio [OR], 0.52; 95% CI, 0.29-0.90). TORS was associated with significantly decreased odds of posttreatment gastrostomy (OR, 0.54; 95% CI. 0.30-0.95) and tracheostomy during treatment (OR, 0.17; 95% CI, 0.06-0.55) at 1 year, and was associated with significantly decreased overall treatment-related costs of care (mean incremental cost, -$22 724).Conclusions and relevanceThe use of TORS for surgical resection of OPC is increasing in the United States and is associated with significantly lower use of adjuvant chemoradiation, late gastrostomy and tracheostomy dependence, and lower overall treatment-related costs of care. These data have implications for discussions of value in OPC care at a time of health care reform.

Project description:ObjectivesTo compare taste changes after transoral robotic surgery (TORS) to taste changes in healthy controls.MethodsOropharyngeal cancer patients receiving TORS and healthy controls were recruited. Participants underwent posterolateral and whole-mouth psychophysical taste testing (identification, intensity, and hedonics) at baseline and at 2 weeks postoperatively (patients) or follow-up (controls). Surgeons reported suspension time and glossopharyngeal nerve injury (GNI) based on the identification and sacrifice of the nerve. A Clinical Global Impression (CGI) of taste symptoms was completed at each session ("My sense of taste bothers me" on a 5-point scale from Never [1] to Always [5]). A taste disorder (TD) was a CGI of 3 (Sometimes) or worse. Within-subject changes in CGI and psychophysical scores were computed. "Worsened taste" was a CGI increase by ≥1 point at follow-up.ResultsOf 69 participants, most (33/37 tumor, 31/32 controls) had normal baseline taste (CGI < 3). 14/33 (42%) TORS patients and no controls developed new TDs at follow-up. More smokers (7/9) had worsened taste than nonsmokers (19/60, difference = 46% [95% CI 16%-76%]). More patients without GNI (6/22) than with GNI (0/15) had postoperative phantogeusia (difference = 27% [95% CI 9-45%]). Tumor-ipsilateral taste identification (TI) decreased more in patients (-11.3%) than controls (0.8%, difference = 12.2% [95% CI 5.0-19.3%]). Suspension time was not associated with worsened taste symptoms or psychophysical changes.ConclusionsPatient-reported taste changes after TORS are frequent. Compared to healthy controls, TORS patients have decreased tumor-ipsilateral TI. Suspension time and GNI are unlikely to cause symptomatic TDs. Further investigations of the etiology and long-term symptom burden of TORS-associated TDs will aid in the management of oropharyngeal cancer patients.Level of evidence3 (non-randomized controlled cohort study) Laryngoscope, 133:3520-3528, 2023.

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:BackgroundTransoral robotic surgery (TORS) or transoral laser microsurgery (TLM) offer excellent oncological outcomes for oropharyngeal squamous cell carcinoma caused by human papillomavirus (HPV) infection. TORS may offer greater margin clearance around tumors than TLM.ObjectiveTo determine whether the differing energy sources used and surgical technique of TORS or TLM is associated with postoperative early swallowing function, feeding tube use, and specific factors related to quality of life.Design, setting, and participantsThis prespecified cohort study was performed within the Postoperative Adjuvant Treatment for HPV-Positive Tumours (PATHOS) randomized clinical trial at 40 centers in the UK, Germany, France, the US, and Australia between November 1, 2015, and August 31, 2023. PATHOS trial participants with HPV-positive oropharyngeal carcinoma of stages T1 to T3 and N0 to N2b M0 (TNM7) who underwent TLM or TORS were eligible. Of 989 consecutively recruited patients on the PATHOS trial, 508 were eligible for this substudy.ExposuresThe exposure of interest was TORS or TLM.Main outcomes and measuresPreplanned outcome measures included nasogastric tube insertion rates within 4 weeks after surgery, length of in-hospital stay following surgery, specific scales from the MD Anderson Dysphagia Inventory (MDADI), 35-item European Organization for Research and Treatment of Cancer Head and Neck Questionnaire (H&N35), and 30-item Quality of Life Questionnaire (QLQ C30), water swallow test results, and videofluoroscopy scores.ResultsOf the 508 patients included in the analysis (390 [76.8%] male; median age, 58.3 [IQR, 52.8-63.6] years), 195 had TLM and 313 had TORS. Nasogastric tube insertion rates were higher after TORS than TLM (85 of 189 [45.0%] vs 10 of 126 [7.9%]; adjusted odds ratio [OR], 4.41 [95% CI, 1.01-19.32]). Mean scores favored TLM with small effect sizes in all MDADI domains and the H&N35 swallowing item at 4 weeks after surgery; between-group difference for the MDADI composite score was -4.89 (95% CI, -8.27 to -1.50); for the MDADI physical functioning score, -6.37 (95% CI, -10.15 to -2.59); for the MDADI global score, -10.02 (95% CI, -16.50 to -3.54); and for H&N35 swallowing score, 7.24 (95% CI, 2.17-12.30). No other measures showed evidence of clinically meaningful differences.Conclusions and relevanceIn this cohort study, functional outcomes were moderately less impaired 4 weeks following TLM compared with TORS. Once the longer-term outcomes for these patients are known, these findings could aid the design and use of future head and neck-specific surgical robots.Trial registrationClinicalTrials.gov Identifier: NCT02215265.
