The impact of socioeconomic and geographic factors on access to transoral robotic/endoscopic surgery for early stage oropharyngeal malignancy

ObjectiveTo evaluate the role of social and geographic factors on the likelihood of receiving transoral robotic surgery (TORS) or non-robotic transoral endoscopic surgery treatment in early stage oropharyngeal squamous cell carcinoma (OPSCC).Materials and methodsThe National Cancer Database was queried to form a cohort of patients with T1-T2 N0-N1 M0 OPSCC (AJCC v.7) who underwent treatment from 2010 to 2016. Demographics, tumor characteristics, treatment type, social, and geographic factors were all collected. Univariate analysis and multivariate logistic regression were then performed.ResultsAmong 9267 identified patients, 1774 (19.1%) received transoral robotic surgery (TORS), 1191 (12.9%) received transoral endoscopic surgery, and 6302 (68%) received radiation therapy. We found that lower cancer stage, lower comorbidity burden and HPV- positive status predicted a statistically significant increased likelihood of receiving surgery. Patients who reside in suburban or small urban areas (>1 million population), were low-to- middle income, or rely on Medicaid were less likely to receive surgery. Patients that reside in Medicaid-expansion states were more likely to receive TORS (p > .0001). Patients that reside in states that expanded Medicaid January 2014 and after were more likely to receive non-robotic transoral endoscopic surgery (p > .0001).ConclusionsPoorer baseline health, lower socioeconomic status and residence in small urban areas may act as barriers to accessing minimally invasive transoral surgery while residence in a Medicaid-expansion state may improve access. Barriers to accessing robotic surgery may be greater than accessing non-robotic surgery.     

Risk factors for gastrostomy tube dependence in transoral robotic surgery patients

ObjectivesTo determine the rate of gastrostomy tube dependence after transoral robotic surgery (TORS), and to determine which patient or surgical factors increase the likelihood of gastrostomy tube dependence.MethodsRetrospective chart review of all patients who underwent TORS for oropharyngeal squamous cell carcinoma (OPSCC) at a single institution from January 2011 through July 2016. Patients who underwent TORS for recurrent OPSCC were excluded. Primary outcome was gastrostomy tube (g-tube) dependence. Univariable and multivariable logistic regression were performed to identify risk factors for g-tube dependence at 3-months and 1-year.ResultsA total of 231 patients underwent TORS during the study period. At 3-month follow-up, 58/226 patients (25.7%) required g-tube. At 1-year and 2-year follow-up, 8/203 (3.9%) and 5/176 (2.8%), remained dependent on g-tube, respectively. Advanced T stage (T3) (OR = 6.07; 95% CI, 1.28–28.9) and discharge from the hospital with enteral access (OR = 7.50; 95% CI, 1.37–41.1) were independently associated with increased risk of postoperative gastrostomy tube dependence at 1 year on multivariable analysis.ConclusionsLong-term gastrostomy tube dependence following TORS is rare, particularly in patients that receive surgery alone. Patients with advanced T stage tumors have poorer functional outcomes. Early functional outcomes, as early as discharge from the hospital, are a strong predictor for long-term functional outcomes.     

Outcomes of transoral laser microsurgery and transoral robotic surgery in oropharyngeal squamous cell carcinoma

ObjectiveTransoral robotic surgery (TORS) has evolved to a standard therapy modality for oropharyngeal carcinoma, especially in T1/ T2 tumors involving the base of the tongue due to its advantages compared with open surgery. However, knowledge about its benefits compared with transoral laser microsurgery (TLM) are scarce. This study compares oncological and functional results of TLM or TORS in the treatment of oropharyngeal squamous cell carcinoma (OPSCC).MethodsThis retrospective analysis comprises all patients with OPSCC treated with TLM (n = 30) or TORS (n = 24) between April 2003 and May 2018 (follow-up 43 ± 38.3 months). Both treatment groups (TLM and TORS) were comparable in terms of the stage of the disease, prognosis-determining factors, and adjuvant therapy modalities.ResultsThere were no significant differences regarding to the resection status (p = 0.272), the rate of local- (p = 0.834) and distant- recurrence (p = 0.416), with a disease-free survival of 86.7 % and 87.5 %, respectively (p = 0.892). In addition, we could not confirm any differences regarding to operating time (p = 0.860), intraoperative blood loss (p = 0.660), inpatient stay (p = 0.585) and postoperative bleeding rate (p = 0.245). The frequency of tracheostomy and percutaneous endoscopic gastrostomy between both groups is comparable, with a longer duration of tube feeding in patients who have received TLM (p = 0.030).ConclusionIn conclusion, TORS allows for similar oncological outcomes compared with TLM at comparable perioperative risks. The postoperative swallowing function may benefit from TORS.     

Transoral robotic surgery in patients with stage III/IV hypopharyngeal squamous cell carcinoma: treatment outcome and prognostic factor

Abstract

Background: We aimed to reduce the morbidity related to treatment and to preserve organ function in patients with hypopharyngeal squamous cell carcinoma (HPSCC) by applying a new surgical treatment protocol based on transoral robotic surgery (TORS).

Aims/objectives: In this study, we analyzed the prognostic factors related to survival to confirm the validity and effectiveness of TORS in patients with advanced-stage HPSCC.

Methods: We retrospectively analyzed the data of 44 HPSCC patients who had undergone TORS-based therapy.

Results: In univariate analysis, only the surgical marginal status showed a statistically significant correlation with the survival of the patients (p?=?.009). In multivariate analysis, surgical margin status was the only statistically significant prognostic factor related to survival (p?=?.008). Forty-one patients (93.2%) recovered speech function sufficiently to perform daily conversation without artificial aids. Forty-one patients (93.2%) were able to ingest food orally.

Conclusions: In the treatment of advanced hypopharyngeal cancer, TORS-based therapy helped the surgeon obtain a clear surgical margin in patients with HPSCC, and it showed superior oncologic and functional outcomes compared to the existing treatment methods.     

Time course of subacute pain after transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma versus traditional bilateral tonsillectomy in adults – a case–control study

Objective: To examine pain after Transoral Robotic Surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) versus traditional bilateral tonsillectomy in adults.

Methods: Pain evolvement was assessed in a prospective case–control design of 16 consecutive patients treated with TORS for early stage OPSCC versus 12 patients, who underwent bilateral tonsillectomy on suspicion of malignant disease. The TORS group received an optimized analgesia regime of preoperative oral celecoxib and gabapentin, intra- and postoperative high-dose intravenous dexamethasone, and regular postoperative oral contalgin, gabapentin, celecoxib, paracetamol and rescue morphine. The tonsillectomy group received the departmental standard analgesia regime with low-dose preoperative oral dexamethasone, celecoxib and paracetamol. Postoperative regular analgesia consisted of oral NSAID and paracetamol with weak opioids prescribed as required. Pain intensity was recorded at rest and during swallowing twice a day.

Results: The median pain intensity on postoperative day (POD) 1–4 was 2 in the TORS group versus 4.5 in the tonsillectomy group. From POD 5-10 median pain intensity was 3.5 and 4, respectively. The median length of stay was 5 days in the TORS group and less than 24?hours in the tonsillectomy group.

Conclusion: With an optimized analgesia regime TORS for OPSCC can be performed with postoperative pain levels comparable to bilateral tonsillectomy in adults.     

Transoral robotic-assisted free flap reconstruction after radiation therapy in hypopharyngeal carcinoma: report of two cases

The objective was to assess the feasibility and safety of transoral robotic surgery (TORS)-assisted free flap reconstruction for hypopharyngeal carcinoma after radiation therapy. The study evaluated the feasibility, surgical margins, the need for a tracheotomy, a nasogastric tube as well as surgery-related complications. Two patients underwent TORS-assisted free flap reconstruction after radiation therapy. The resection margins were free of tumor in both patients. A tracheotomy was performed in one patient who had been decannulated on the sixth postoperative day. One patient resumed satisfactory oral feeding in the fourth postoperative month and the second patient on postoperative day 7. No intraoperative complication and one postoperative complication (neck hematoma) were reported. After a follow-up period of 24 and 30 months, no local recurrence was observed. TORS is feasible for hypopharyngeal resection and assisted free flap reconstruction after radiation therapy. It represents a further step in the development of minimally invasive surgery for the treatment of head and neck cancers with laryngeal preservation.     

Role of local flaps in the prevention of soft tissue necrosis after transoral robotic surgery for tonsillar cancer

ObjectiveSoft tissue necrosis (STN) can occur after transoral robotic surgery (TORS) with radiation therapy (RT). We investigated the usefulness of local flap reconstruction for preventing STN after TORS in patients with tonsillar cancer.MethodsThis case-control study retrospectively reviewed clinicopathological data of patients who underwent TORS for tonsillar cancer at a tertiary referral center. The incidence of STN was compared in patients who underwent secondary intention healing or local flap reconstruction, and factors predicting STN were identified.ResultsSTN occurred in 20 (25%) of 80 patients in the study. The incidence of STN was higher in the secondary intention healing than the flap reconstruction group. Mucositis grade (odds ratio [OR] 3.694, p = 0.02), RT dose (OR 4.667, p = 0.001), and secondary intention healing (OR 14.985, p = 0.035) were predictive factors for STN.ConclusionFlap reconstruction can prevent STN after TORS with RT in patients with tonsillar cancer. The use of local flaps preserves the minimally invasive nature of TORS.     

National analysis of positive surgical margins in oropharyngeal salivary gland malignancies

ObjectivePositive surgical margins (PSM) are associated with worse survival in oropharyngeal salivary gland malignancies (OPSGM), but existing literature is limited to small series. Our objective was to identify risk factors for PSM using the national cancer database (NCDB), including a transoral robotic surgical (TORS) approach.MethodsNCDB was queried for patients with T1-T4a OPSGM undergoing resection between 2010 and 2017. Risk factors for PSM were determined using logistic regression. Overall survival (OS) was analyzed using Kaplan-Meier and Cox proportional hazards models.ResultsOf 785 patients, 165 (21.0 %) had PSM. Age, stage T4a tumors (OR 2.00, 95 % Confidence Interval [CI]: 1.03–3.88), adenoid cystic carcinoma (OR 2.02, 95 % CI: 1.29–3.18), and treatment at lower volume institutions (OR 1.68, 95 % CI: 1.09–2.59) were all independently associated with PSM. TORS versus a non-robotic approach was not associated with PSM (23.9 % vs 20.4 %, p 0.358), respectively. Positive margins were independently associated with a worse OS than negative margins (HR 1.63, 95 % CI: 1.03–2.59). Adjuvant radiation therapy was associated with improved survival in high grade tumors with positive margins.ConclusionThis study represents the largest review assessing risk factors for positive margins in OPSGM. Histologic type (adenoid cystic carcinoma), age, T4a tumor stage and treatment at a lower volume institution were all predictive of positive margins. With increasing use of TORS over the last decade, there does not appear to be a greater risk of positive margins using this modality in select patients.Level of evidence: N/A.     

Comparative cost of transoral robotic surgery and radiotherapy (IMRT) in early stage tonsil cancer

PurposeTo compare treatment costs and cost-effectiveness for transoral robotic surgery (TORS) and definitive intensity-modulated radiotherapy (IMRT) in managing early stage tonsil cancer.Materials and methodsDirect treatment costs for surgery and IMRT were calculated from SEER-Medicare data for a cohort with clinically early stage (cT1/2N0) p16+ tonsillar squamous cell carcinoma from Kaiser Permanente Southern California Health Plan between 2012 and 2017. A Markov decision tree model with a 5-year time horizon was then applied to the cohort which incorporated costs associated with treatment, surveillance, and recurrence.ResultsIMRT cost up to $19,000 more (35%) than TORS in direct treatment costs. When input into the Markov model, TORS dominated IMRT with lower cost and better effectiveness over a range of values.ConclusionTORS is a more cost-effective treatment method than IMRT in early stage (cT1/2N0) tonsil cancer.     

Transoral robotic surgery for head and neck carcinomas

The objective of this study was prospectively to assess the feasibility and safety of transoral robotic surgery (TORS) in head and neck carcinomas and to report our learning curve and 2-year outcomes. Patients with oropharyngeal, hypopharyngeal and laryngeal tumors treated with TORS were prospectively included. We evaluated: the feasibility of TORS, robotic set-up time, transoral robotic surgery time, blood loss, surgical margins, tracheotomy, feeding tube, time to oral feeding and surgery-related complications. Twenty-three patients were treated for 25 carcinomas. Twenty-two patients underwent successful robotic resection for 24 carcinomas (96%). One patient required conversion to open surgery due to massive bleeding. The mean robotic set-up time was 25?min (range: 15–100?min) and mean TORS operating time was 70?min (range: 20–150?min). Positive margin of resection was observed in one patient (classified pT3) out of the 24 cancers and was managed by postoperative chemoradiation. No tracheotomy was performed. Three patients required prolonged intubation for a mean of 22?h. Two patients required a temporary gastrostomy (for 2 and 3.5?months, respectively). All other patients resumed oral feeding between the first and third postoperative day. The mean hospital stay was 6.4?days (range: 4–19?days). No postoperative complication occurred. Mean follow-up was 20?months (median: 19, range: 14–26). No death and no case of local or metastatic failure were observed. TORS is feasible and safe for the resection of selected head and neck carcinomas. The occurrence of intraoperative bleeding emphasizes the need for surgeons to be skilled in both transoral and open approaches.     

Transoral robotic surgery for oropharyngeal cancer in the era of chemoradiation therapy

Over time, the primary treatment modality of oropharyngeal squamous cell cancers (OPSCC) is intensity-modulated radiation therapy (IMRT), eventually associated with chemotherapy (CHT). This treatment modality is preferred for reduced impact on the quality of life rather than aggressive open surgical approaches. The advent of TransOral Robotic Surgery (TORS) has rediscovered the role of surgery in the treatment of OPSCC. Although the primary chemoradiation therapy (CRT) and transoral robotic surgery (TORS) are competing for similar oncologic results, CRT may result in significant functional complaints such as severe dysphagia and feeding tube dependence and, on the other hand, TORS might result in surgical defects depending on the size of the resection and anatomic location. Nevertheless, TORS may intercept the locoregionally advanced population through pathologic downstaging as well as the potential for improvement in oncologic outcomes. The available reconstructive options allow an expanding role of this minimally invasive surgery, even in locally advanced tumours. Finally, the surgical management of OPSCC with TORS identifies areas of opportunity in shortening the overall treatment package time compared to traditional surgery.     

Comparison of radiofrequency and transoral robotic surgery in obstructive sleep apnea syndrome treatment

Introduction: Radiofrequency tissue ablation (RFTA) and transoral robotic surgery (TORS) are the methods used in OSAS surgery. We also aimed to compare the advantages and disadvantages of RF and TORS as treatment methods applied in OSAS patients in terms of many parameters, especially apnea hypopnea index (AHI).

Materials and methods: Patients were classified by performing a detailed examination and evaluation before surgery. 20 patients treated with anterior palatoplasty and uvulectomy ?/+ tonsillectomy?+?RFTA (17 males, 3 females) and 20 patients treated with anterior palatoplasty and uvulectomy ?/+ tonsillectomy?+?TORS (16 males, 4 females) were included in the study. PSG was performed preoperatively and postoperatively in all patients and Epworth sleepiness questionnaire was applied. All operations were performed by the same surgeon and these surgical methods -RF and TORS- were compared in terms of many parameters.

Results: When the patients treated with RF and TORS were compared in operation time, length of hospitalization and duration of transition to oral feeding; all parameters were significantly greater in the patients treated with TORS.

Conclusions: TORS technique was found to be more successful than RF in terms of reduction of AHI value, correcting minimum arterial oxygen saturation value and decreasing Epworth Sleepiness Scale score.     

Surgical management of Eagle syndrome: A 17-year experience with open and transoral robotic styloidectomy

Eagle Syndrome (ES) is a rare disorder that can present with symptoms ranging from globus sensation to otalgia that is attributed to an elongated styloid process and/or calcified stylohyoid ligament. No standardized treatment algorithm exists, and although various surgical approaches have been described, data on the use of transoral robotic surgery (TORS) in this population is limited. To investigate the utility of TORS in the treatment of ES, a retrospective review in 19 ES patients was carried out at a single academic, tertiary medical center between 2000 and 2017. Nineteen patients underwent twenty-one styloid resections: 6 performed via TORS and 15 via transcervical approach. Across all patients, 90% reported some degree of lasting improvement in symptoms while 55% reported significant improvement. When TORS was compared to transcervical resection, there was no difference in the subjective rate of “meaningful” (83 vs. 57%) versus rate of “non-meaningful” symptom improvement (17 vs. 43%) (p = 0.35). There was a trend towards less estimated blood loss (EBL), operative time, and post-operative length of stay (LOS) with TORS versus transcervical cases (9.2 mL vs. 30.0 mL, 98 vs. 156 min, and 0.7 vs. 1.2 days); however, these did not reach statistical significance (p = .11, 0.13, and 0.42, respectively). Three patients experienced complications associated with an open approach, as compared to none with TORS. In select patients, TORS styloidectomy is a reasonable surgical alternative to traditional transoral and transcervical techniques as it provides similar symptom improvement, and reduced length of stay, blood loss, and operative time.     

Impact of resection margin status and revision transoral laser microsurgery in early glottic cancer: analysis of organ preservation and local disease control on a cohort of 153 patients

IntroductionTransoral laser microsurgery represents the treatment of choice for early glottic cancer. Its use and effectiveness are mainly related to laryngeal exposure and deep extension of tumor. Histopathologic assessment of surgical margin presents a main issue about transoral laser microsurgery and complete oncological excision.ObjectiveThe aim was to analyze the impact of revision surgery on organ preservation and local disease control in patients with early glottic cancer treated by transoral laser microsurgery.MethodsWe carried out a retrospective study on a cohort of 153 patients with early glottic cancer (Tis, T1, T2) treated by transoral laser microsurgery. Resection margins were classified as follows: “free” if macroscopic margin-tumor distance was at least 2 mm, as “close” if it was less than 2 mm and “positive” if the margin was involved by carcinoma. Patients were divided into two groups: patients with free resection margins (Group A) and patients with positive, close or not-evaluable resection margins (Group B). Group A (36) underwent periodic followup. Group B (117) underwent a second look laser CO₂ 2 months after surgery. Fifteen patients of Group A with suspected persistence of carcinoma during followup underwent a second laser resection after a time interval of 4–8 months after first surgery. Overall survival, disease-free survival, disease-specific survival, ultimate local control with laser alone and organ preservation rates were estimated.ResultsFive-year overall survival rate and 5-year disease-specific survival were 100% in both groups. The five-year laryngeal preservation rate was 100% in Group A and 95.2% in Group B. Five-year disease-free survival was 92.15% and 5-year ultimate local control with laser alone in 92.15% of patients.ConclusionThis study has demonstrated that revision Transoral Laser Microsurgery is able to confirm the oncological radicality in most cases, even in the case of positive, close or non-evaluable margins. Considering our results, according to our experience, the second look with CO₂ laser is a therapeutic strategy to consider, even in the case of close or non-evaluable as well as positive margins.     

Intraoperative imaging during minimally invasive transoral robotic surgery using near-infrared light

Purpose

The purpose of this study was to determine if the use of the FIREFLY imaging system could be an asset in transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC). The system uses indocyanine green dye (ICG), which fluoresces when illuminated by near-infrared light from the Da Vinci robot. The system may improve visualization of tumor margins, highlight important vascular structures, and help identify the location of tumors and unknown primary head and neck cancers.

Evaluation of robotic surgery for transoral resection of T1-2 squamous cell carcinoma of the tonsillar fossa

GoalTo evaluate transoral robotic surgery (TORS) for isolated previously untreated squamous cell carcinoma (SCC) of the tonsillar fossa classified as T1-2.MethodRetrospective analysis of two cohorts of isolated untreated T1-2 tonsillar fossa SCC consecutively operated on by a transoral approach, with (R = 21) and without (NR = 24) robotic assistance, in the period 2006–2014. Three main (survival, local control, and operative morbidity) and three secondary (pathologic data, incidence and duration of tracheotomy and nasogastric intubation, and hospital stay) endpoints were compared between groups. The significance threshold was set at P <  .005.ResultsThree- and five-year actuarial survival estimates were 80.2% and 74.5% respectively in group R, and 91.5% and 82.5% respectively in group NR (NS: P = .34). Three- and five-year actuarial local control estimates were 90% and 90% respectively in group R, and 95.8% and 91% respectively in group NR (NS: P = .81). There were no significant differences in morbidity, tracheotomy/nasogastric intubation time, or hospital stay. Positive resection margins (R1) were noted in 38.1% and 16.7% in groups R and NR, respectively (NS: P = .05) without significant impact on 5-year actuarial local control (P = 0.78).ConclusionRobotic assistance in transoral lateral oropharyngectomy for T1-2 tonsillar fossa SCC did not significantly impact oncologic or functional outcome.     

Neck dissection and trans oral robotic surgery for oropharyngeal squamous cell carcinoma

ObjectiveTrans Oral Robotic Surgery (TORS) is a modality in the management of oropharyngeal squamous cell carcinoma(OPSCC). This study was planned to determine whether Selective Neck Dissection (SND) is oncological safe procedure even in patients with lymph node metastases.MethodsOPSCC patients were divided into Modified Radical Neck Dissection (MRND) and SND groups. The outcome measures were overall survival (OS), disease-free survival (DFS) and regional recurrence free survival (RRFS).ResultsThirty-seven SNDs and 18 MRNDs were performed. Regional relapse rate was 6.1% in SND group whilst 18.8% in MRND group(p=0.19). The 5-year OS, DFS and RRFS rates’ differences were not statistically significant between SND and MRND groups (p=0.40, p=0.42 and p=0.18, respectively). At multivariate analysis, advanced stage impacted the 5-year OS and DFS(HR=9.39, p<0.01 and HR=11.03, p=0.04).ConclusionsThe SND seems to be effective in a TORS framework. The indication should be accurately discussed by the multidisciplinary tumor board.     

Clinical characteristics and prognosis of patients with hypopharyngeal cancers with multiple primary cancers: A propensity score matched analysis

PurposeThis study aimed to identify the clinical characteristics of hypopharyngeal squamous cell carcinoma (HPSCC) patients with multiple primary cancers (MPCs) and to compare differences between patients with metachronous and synchronous MPCs.Material and methodsThis study included 219 patients with HPSCC treated at our center between 2008 and 2020; the clinical characteristics and prognosis of 66 patients with MPCs were analyzed. Propensity score matching (PSM) was used to balance the factors between patients with synchronous and metachronous MPCs.ResultsSixty-six patients with HPSCC (66/219, 30.1%) experienced MPCs, of which 29 were synchronous and 37 were metachronous. The esophagus (n = 39, 59.1%), lung (n = 10, 15.2%), and oropharynx (n = 4, 6.1%) were the three most common sites of MPCs in both the synchronous and metachronous groups. More patients with synchronous MPCs were stage T1–2 (82.8% vs. 59.5%, P = 0.041) compared to those with metachronous MPCs. Among the 24 pairs of patients after PSM, patients with metachronous MPCs had higher 3-year progression-free survival (PFS) (52.5% vs. 16.3%, P < 0.001) and overall survival (OS) (58.5% vs. 22.1%, P = 0.001) than those with synchronous cancers. Multivariate Cox analysis showed that patients with synchronous MPCs had shorter PFS (HR 4.45, 95% CI 1.819–10.885, P = 0.001) and OS (HR 3.918, 95% CI 1.591–9.645, P = 0.003).ConclusionMPCs are common among patients with HPSCC, and patients with metachronous MPCs had better survival than those with synchronous MPCs. Clinicians should be aware of the possibility of MPCs in patients with HPSCC and optimize treatment to improve outcomes.
