Oral Cavity Cancer Surgical and Nodal Management: A Review From the American Head and Neck Society.

Importance: Lymph node metastases from oral cavity cancers are seen frequently, and there is still inconsistency, and occasional controversies, regarding the surgical management of the neck in patients with oral cancer. This review is intended to offer a surgically focused discussion of the current recommendations regarding management of the neck, focusing on the indications and extent of dissection required in patients with oral cavity squamous cell carcinoma while balancing surgical risk and oncologic outcome. Observations: The surgical management of the neck for oral cavity cancer has been robustly studied, as evidenced by substantial existing literature surrounding the topic. Prior published investigations have provided a sound foundation on which data-driven treatment algorithms can generally be recommended. Conclusions: Existing literature suggests that patients with oral cavity cancer should be fully staged preoperatively, and most patients should receive a neck dissection even when clinically N0. Quality standards supported by the literature include separation of each level during specimen handling and lymph node yield of 18 or more nodes. Sentinel lymph node biopsy can be considered in select tumors and within a well-trained multidisciplinary team.

Survival Outcomes in T3 Laryngeal Cancers: Primary Total Laryngectomy vs. Concurrent Chemoradiation or Radiation Therapy-A Meta-Analysis.

BACKGROUND: The management of cT3 laryngeal cancers remains controversial, with studies recommending surgical or non-surgical approaches. Despite the many papers that have been published on the subject, there is a lack of studies showing which treatment has better results in terms of survival. OBJECTIVE: To determine the difference in survival outcomes following total laryngectomy (TL), concurrent chemoradiation (CRT) or radiation therapy (RT) alone in T3 laryngeal cancers. METHODS: Search of PubMed, Scopus, and Google Scholar databases from 1995 to 2023 employing specific keywords and Boolean operators to retrieve relevant articles. Statistical analysis was conducted using a random-effects model, and heterogeneity was evaluated using the Q-test and I2 statistic. Funnel plot asymmetry was assessed using rank correlation and regression tests. RESULTS: The qualitative data synthesis comprised 10,940 patients from 16 included studies. TL was performed in 2149 (19.4%), CRT in 6723 (61.5%), RT in 295 (2.7%), while non-surgical treatment was not specified in 1773 (16.2%) patients. The pooled 2-year overall survival (OS) rates were TL = 73%, CRT = 74.7%, RT = 57.9%, 3-year OS rates were TL = 64.3%, CRT = 62.9%, RT = 52.4%, and 5-year OS rates were TL = 54.2%, CRT = 52.7%, RT = 40.8%. There was a significant heterogeneity in the included studies. There was no statistically significant difference in 2-year OS (logOR= -0.88 (95% confidence interval (CI): -1.99 to 0.23), p = 0.12), 3-year OS (logOR = -0.6 (95% CI: -1.34 to 0.15), p = 0.11), and 5-year OS (logOR = -0.54 (95% CI: -1.29 to 0.21), p = 0.16) between TL and CRT. Instead, there was significant difference in 2-year OS (logOR= -1.2383 (95% CI: -2.1679 to -0.3087), p = 0.009), 3-year OS (-1.1262 (95% CI: -1.6166 to -0.6358), p < 0.001), and 5-year OS (-0.99 (95% CI: -1.44 to -0.53)), p < 0.001) between TL and RT alone. CONCLUSIONS AND SIGNIFICANCE: TL followed with adjuvant (chemo)radiation on indication and CRT with salvage surgery in reserve appear to have similar OS outcomes. Both resulted in better OS outcomes compared to RT alone in the treatment of T3 laryngeal cancers. If patients are unfit for chemotherapy, making CRT impossible, surgery may become the choice of treatment.

Real world data on long term outcome of neoadjuvant chemotherapy in locally advanced esthesioneuroblastoma and sinonasal tumor with neuroendocrine differentiation - Results from a single centre study.

INTRODUCTION: Esthesioneuroblastoma and sinonasal neuroendocrine carcinoma (SNEC) are the most common histological subtypes of non-squamous Sinonasal Tumors. A multidisciplinary approach is preferred for locally advanced unresectable esthesioneuroblastoma and SNEC. METHODS: From June 2010 to October 2021, 59 patients with esthesioneuroblastoma and SNEC received NACT. NACT consists of 2-3 cycles of Etoposide-Platinum based chemotherapy. Depending upon response and performance status, subsequent therapy was planned. SPSS descriptive statistics were performed for analysis. Kaplan Meir methods were used for the estimation of Progression Free Survival (PFS) and Overall Survival (OS). RESULTS: 45 (76.3 %) Esthesioneuroblastoma and 14 (23.7 %) SNEC patients received NACT. The median age of the population was 45 years (range 20-81 years). The majority of patients received 2-3 cycles of Platinum (Cisplatin or Carboplatin) + Etoposide as NACT. 28 patients (47.5%) underwent surgery and 20 patients (33.9%) received definitive chemoradiotherapy after NACT. The most common grade 3 or above adverse events were anemia (13.6%), neutropenia (27.1), and hyponatremia (45.8%). At the time of analysis, the median PFS was 56 months (95% CI 31 months to 77 months), and the median OS was 70 months (95% CI 56 months to 86 months). The most common late toxicities noticed were metabolic syndrome (42.4%), hyperglycemia (39%), nasal bleeding (33.9%), hypertension (17%), dyslipidemia (8.5%), and hypothyroidism (5.1%). CONCLUSION: The study shows that NACT is safe, and can be easily delivered without any life-threatening toxicities, with a favorable response and improved survival in this subset of patients.

Neoadjuvant chemotherapy in a rare type of very locally advanced sinonasal carcinomas - long-term results from a tertiary care centre.

Introduction: Sinonasal carcinomas are a rare type of head and neck malignancy with various histologies. The outcomes of patients with unresectable locally advanced sinonasal carcinomas are poor. Hence, we performed this analysis to study the long-term outcomes of sinonasal adenocarcinoma (SNAC) and sinonasal undifferentiated carcinomas (SNUC) where neoadjuvant chemotherapy (NACT) has been given followed by local therapy. Methods: 16 patients with SNUC and adenocarcinoma who received NACT were found eligible for the study. Descriptive statistical analysis was performed for baseline characteristics, adverse events and treatment compliance. Kaplan Meir methods were used for the estimation of progression-free survival (PFS) and overall survival (OS). Results: Seven (43.75%) adenocarcinoma and nine (56.25%) SNUC patients were identified. The median age of the whole cohort was 48.5 years. The median number of cycles delivered was 3 (IQR 1-8). The incidence of grade 3-4 toxicity (CTCAE version 5.0) was 18.75%. The response was partial response or better in seven patients (43.75%). Post-NACT 11 patients (n = 15, 73%) were eligible for definitive therapy. The median PFS was 7.63 months (95% CI, 3.23 - NA months) and the median OS was 10.6 months (95% CI, 5.2-51.5 months). Median PFS and OS for those who underwent surgery post-NACT versus those who did not undergo surgery were 36.267 versus 3.7 months (p = 0.012) and 51.5 versus 10.633 months (p = 0.190), respectively. Conclusion: The study shows a favourable role of NACT in improving resectability, significant improvement in PFS and non-significant improvement in OS after surgery.

Results of Phase III Randomized Trial for Use of Docetaxel as a Radiosensitizer in Patients With Head and Neck Cancer, Unsuitable for Cisplatin-Based Chemoradiation.

PURPOSE: There is a lack of published literature on systemic therapeutic options in cisplatin-ineligible patients with locally advanced head and neck squamous cell carcinoma (LAHNSCC) undergoing chemoradiation. Docetaxel was assessed as a radiosensitizer in this situation. METHODS: This was a randomized phase II/III study. Adult patients (age ≥ 18 years) with LAHNSCC planned for chemoradiation and an Eastern Cooperative Oncology Group performance status of 0-2 and who were cisplatin-ineligible were randomly assigned in 1:1 to either radiation alone or radiation with concurrent docetaxel 15 mg/m2 once weekly for a maximum of seven cycles. The primary end point was 2-year disease-free survival (DFS). RESULTS: The study recruited 356 patients between July 2017 and May 2021. The 2-year DFS was 30.3% (95% CI, 23.6 to 37.4) versus 42% (95% CI, 34.6 to 49.2) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.673; 95% CI, 0.521 to 0.868; P value = .002). The corresponding median overall survival (OS) was 15.3 months (95% CI, 13.1 to 22.0) and 25.5 months (95% CI, 17.6 to 32.5), respectively (log-rank P value = .035). The 2-year OS was 41.7% (95% CI, 34.1 to 49.1) versus 50.8% (95% CI, 43.1 to 58.1) in the RT and Docetaxel-RT arms, respectively (hazard ratio, 0.747; 95% CI, 0.569 to 0.980; P value = .035). There was a higher incidence of grade 3 or above mucositis (22.2% v 49.7%; P < .001), odynophagia (33.5% v 52.5%; P < .001), and dysphagia (33% v 49.7%; P = .002) with the addition of docetaxel. CONCLUSION: The addition of docetaxel to radiation improved DFS and OS in cisplatin-ineligible patients with LAHNSCC.[Media: see text].

Prospective Phase II Open-Label Randomized Controlled Trial to Compare Mandibular Preservation in Upfront Surgery With Neoadjuvant Chemotherapy Followed by Surgery in Operable Oral Cavity Cancer.

PURPOSE: The objective of this study was to explore the potential role and safety of neoadjuvant chemotherapy (NACT) in tumor shrinkage and resultant mandibular preservation in oral cancers compared with conventional surgical treatment. METHODS: This study was a single-center, randomized, phase II trial of treatment-naive histologically confirmed squamous cell carcinoma of the oral cavity with cT2-T4 and N0/N+, M0 (American Joint Committee on Cancer, seventh edition) stage, necessitating resection of the mandible for paramandibular disease in the absence of clinicoradiologic evidence of bone erosion. The patients were randomly assigned (1:1) to either upfront surgery (segmental resection) followed by adjuvant treatment (standard arm [SA]) or two cycles of NACT (docetaxel, cisplatin, and fluorouracil) at 3-week intervals (intervention arm [IA]), followed by surgery dictated by postchemotherapy disease extent. All patients in the IA received adjuvant chemoradiotherapy, and patients in the SA were treated as per final histopathology report. The primary end point was mandible preservation rate. The secondary end points were disease-free survival and treatment-related toxicity. RESULTS: Sixty-eight patients were enrolled over 3 years and randomly assigned to either SA (34 patients) or IA (34 patients). The median follow-up was 3.6 years (interquartile range, 0.95-7.05 years). Mandibular preservation was achieved in 16 of 34 patients (47% [95% CI, 31.49 to 63.24]) in the IA. The disease-free survival (P = .715, hazard ratio 0.911 [95% CI, 0.516 to 1.607]) and overall survival (P = .747, hazard ratio 0.899 [95% CI, 0.510 to 1.587]) were similar in both the arms. Complications were similar in both arms, but chemotherapy-induced toxicity was observed in the majority of patients (grade III: 14, 41.2%; grade IV: 11, 32.4%) in the IA. CONCLUSION: NACT plays a potential role in mandibular preservation in oral cancers with acceptable toxicities and no compromise in survival. However, this needs to be validated in a larger phase III randomized trial.

Anaplastic Cancer: Our Experience.

Anaplastic thyroid carcinoma (ATC) is a rare thyroid malignancy with a dire prognosis, nearly 100% disease specific mortality and a median overall survival less than 6 months. In view of the limited data from India on anaplastic thyroid cancer, we conducted this audit to analyze the treatment pattern, outcomes and factors influencing it. This is a retrospective analysis of outcomes of patients treated in a single institution between January 2008 and December 2020. Baseline characteristics, treatment received, and outcomes among adult patients with ATC were collected. Progression free survival (PFS) and overall survival (OS) were analyzed. SPSS version 20 and RStudio version 3.1.1 were used for analysis. In this cohort of 134 patients, the median age at diagnosis was 59 years, with 63.4% of them being females. At presentation, 70.9% of them had good performance status (PS 0-1). Only 38.8% received treatment with curative intent (either surgery fb adjuvant or neoadjuvant chemotherapy fb surgery and adjuvant or definitive chemoradiotherapy) while 61.2% patients received palliative treatment (either palliation alone or palliative chemotherapy or palliative surgery or palliative RT). Predominant pattern of progression was local progression (79.8%). Median PFS and OS of the overall cohort were 58 days and 80 days respectively. PFS and OS were significantly better in patients treated with curative intent vs palliative intent (116 and 134 days vs 45 and 50 days; p = 0.00 and 0.00 respectively). Among patients treated with curative intent, OS was significantly better in patients undergoing surgery vs CTRT (155 vs 76 days; p = 0.03). Among patients treated with upfront surgery, both PFS and OS were better with the addition of adjuvant CTRT/RT vs no adjuvant (332 and 540 days vs 55 and 91 days; p = 0.00 and 0.003 respectively). ATC is a rare cancer with dismal prognosis. Local therapy with surgery followed adjuvant seems to be associated with the better outcomes. Systemic therapy seems to be a better option for palliation. Our data reflects the real world data of this rare cancer.

Is Direct Laryngoscopy Obsolete? "Trans Nasal Oesophagoscopy" the Complete Endoscopic Solution in Head Neck Practice.

Direct laryngoscopy (DL) is the standard of care for the evaluation of suspicious lesions in the larynx and hypo pharynx but requires general anaesthesia and a dedicated operation theatre. While DL offers us the ability to map the lesion adequately and take a biopsy, it requires workup for anaesthesia well as rigid oesophagoscopy for assessing the oesophagus with its associated complications. Sixty-nine patients underwent TNE under topical anaesthesia. The lesions were mapped and biopsies taken. Those patients who had an inadequate evaluation on TNE or negative biopsy underwent direct laryngoscopy. Completeness of evaluation, adequacy of biopsy, presence of synchronous oesophageal lesions and the modified Gloucester Comfort Score for patient comfort was documented. Amongst 69 cases enrolled for TNE evaluation, 97% of cases had an adequate mapping of disease extent, and 100% adequacy of biopsy material. General anaesthesia could be avoided in 92.75% of patients. TNE took a median time of 8 min. Synchronous oesophageal tumours were seen in 5.8% of patients. There were no complications and 74% patients did not experience any discomfort. TNE appears to be simple, safe, efficient office based diagnostic procedure. TNE has the potential to be the new standard of care making DL obsolete.

Transnasal Endoscopic Resection of the Intraconal Metastases From Renal Cell Carcinoma: a Case Report and Review of Literature.

Renal cell carcinoma (RCC) is the most common malignancy to cause metastasis to sinonasal cavity. These metastases can occasional cause invasion into the orbit. Isolated intraconal intraorbital metastasis from RCC is very rare. We hereby describe a case of 72-year-old female, who underwent right nephrectomy for RCC, 8 years back, and now presenting with a space occupying lesion in the right intraorbital intraconal compartment with no involvement of the paranasal sinuses. En bloc resection of the tumor was achieved via transnasal endoscopic approach. This is a rare case where minimally invasive surgery was done for metastatic lesion, with minimal postoperative morbidity.

Masseter Flap for Reconstruction of Defects After Excision of Buccal Mucosa Cancers with Intact Mandible.

Among the reconstructive options available for buccal mucosa defects with an intact mandible, free flap with microvascular anastomosis is the best option. However, in the developing world, with poor resources, limited in- frastructure, and high patient load, this cannot be offered to all patients. We report on the success of the masseter flap for reconstruction of such defects in carefully selected patients. Despite some known limitations, this flap is easy to learn and carries acceptable complications. The results of this flap may not be comparable to those of microvas- cular reconstructions, but they are better than those from other options such as skin graft, nasolabial flap, submental flap, etc. in terms of surgical time required, no donor site morbidity, and minimal aesthetic deformity.

Anesthesia for oral surgeries during the COVID-19 pandemic.

The severe acute respiratory syndrome corona virus 2(SARS-Cov2) virus replicates in the nasal cavity, nasopharynx, and the oropharynx. During oral surgery, the risk of viral transmission is high during instrumentation in these areas, while performing airway management procedures, the oral surgery itself, and related procedures. During the corona virus disease 2019 (COVID-19) pandemic, patients with an oral pathology usually present for emergency procedures. However, patients with oral cancer, being a semi-emergency, may also present for diagnostic and therapeutic procedures. When elective surgeries are resumed, these patients will come to the operating room. In asymptomatic patients, the false-negative rate can be as high as 30%. These patients are a source of infection to the healthcare workers and other patients. This mandates universal precautions to be taken for all patients presenting for surgery. Lesions along the airway, distorted anatomy secondary to cancer therapy, shared airway with the surgeon, surgical handling of the airway and the risk of bleeding, make airway management challenging in these patients, especially while wearing personal protective equipment. Airway management procedures, oral surgery, use of cautery, and other powered surgical instruments in the aero digestive tract, along with constant suctioning are a source of significant aerosol generation, further adding to the risk of viral transmission. Maintaining patient safety, while protecting the healthcare workers from getting infected during oral surgery is paramount. Meticulous advance planning and team preparation are essential. In this review, we discuss the challenges and recommendations for safe anesthesia practice for oral surgery during the COVID-19 pandemic, with special emphasis on risk mitigation.

Other Rare Sinonasal Malignant Tumours Involving the Anterior Skull Base.

Sinonasal tumours are rare, and among these there exist a small number of histologic subtypes that are infrequently encountered and rarely mentioned in the literature. These have been presented as either case reports or small case series, and their very low incidence makes prospective studies practically impossible. This review analyses the available literature, including our own experience and endeavours to outline management strategies, which involve a high index of suspicion and counselling of patients. In most instances, these tumours require aggressive multimodal treatment to improve survival outcomes. The overall prognosis remains dismal.

Nimotuzumab-cisplatin-radiation versus cisplatin-radiation in HPV negative oropharyngeal cancer.

BACKGROUND: Addition of nimotuzumab to weekly cisplatin and radiation improves outcomes in head and neck cancer. HPV negative oropharyngeal cancer has unsatisfactory treatment outcomes and is a candidate for escalation of treatment. We wanted to determine whether the addition of nimotuzumab to cisplatin-radiation could improve outcomes in these poor-risk tumors. METHODS: This was a subgroup analysis of a phase 3 randomized study. In this study, locally advanced head and neck cancer patients undergoing definitive chemoradiation were randomly allocated to weekly cisplatin (30 mg/m2 IV)- radiation (66-70 Gy) {CRT arm} or nimotuzumab (200 mg weekly) -weekly cisplatin (30 mg/m2)-radiation (66-70 Gy) {NCRT arm}. The data of HPV negative oropharyngeal cancer was extracted from the database of this study for the analysis. HPV testing was done with p16 immunohistochemistry (IHC) staining and reported according to the CAP criteria. The outcomes assessed were progression-free survival (PFS), disease-free survival (DFS), locoregional control, and overall survival (OS). Interaction test was performed between the study arms and HPV status prior to doing any HPV specific analysis for each of the studied outcomes. Kaplan Meier estimates for 2 year OS with 95%CI was calculated. The hazard ratio was obtained using COX regression analysis. RESULTS: We had 187 HPV negative oropharyngeal cancers, 91 in the CRT arm and 96 in NCRT arm. The interaction test was significant for PFS (p = 0.000), locoregional control (p = 0.007) and overall survival (p = 0.002) but not for DFS (p = 0.072). The 2- year PFS was 31.5% (95%CI 21.5-42) in CRT arm versus 57.2% (95%CI 45.8-67.1) in NCRT arm (HR -0.54; 95%CI 0.36-0.79, p = 0.002). The 2-year LRC was 41.4% (95%CI 29.8-52.6) in the CRT arm versus in 60.4% (95%CI 48.7-70.2) in the NCRT arm (HR -0.61; 95%CI 0.4-0.94, p = 0.024). The addition of nimotuzumab also lead to an improvement in 2-year OS from 39.0% (95%CI 28.4-49.6) to 57.6% (95%CI 46.3-67.4) (HR-0.63, 95%CI 0.43-0.92, p = 0.018). CONCLUSIONS: The addition of nimotuzumab to weekly cisplatin-radiation improves outcomes inclusive of OS in HPV negative oropharyngeal cancers.

Salvage surgery in head and neck cancer: Does it improve outcomes?

BACKGROUND: Studies reporting outcomes of salvage surgery in locally advanced head and neck squamous cell carcinoma (LAHNSCC) have inherent biases like biological and temporal selection. Our study considered all patients deemed fit for salvage surgery and compared to those who underwent surgery versus those who refused it thus throwing light on the real world benefit of salvage surgery. METHODS: This was a post hoc analysis of a phase 3 randomized trial conducted between 2012 and 2018. Out of 536 LAHNSCC patients randomised in the study, 113 patients had residual disease or recurrent disease and were planned for salvage surgery in a multidisciplinary clinic. Patients were divided into 2 cohorts for comparison, willing for salvage surgery (n = 91) and unwilling for salvage surgery(n = 22). The primary endpoint was overall survival. RESULTS: The median follow up was 28.7 months (95%CI 23.9-33.5 months). Out of the 91 patients who were willing for salvage surgery, 78 underwent same. The median survival in cohort of patients willing for salvage surgery was 22.0 months (95%CI 10.1-33.9) while it was 9.7 months (95%CI 6.6-12.8) in patients who were unwilling for salvage surgery (HR = 0.262 95%CI HR 0.147-0.469, p = 0.000). CONCLUSION: Salvage surgery leads to a substantial improvement in outcomes in head and neck cancers and should be the de facto standard of care in patients who are eligible for the same.

Demography and treatment pattern of patients with head and neck carcinoma presenting to a tertiary care center in India: Need for urgent decentralization of cancer care.

AIMS: This study aims to report on the demographic profile and treatment pattern of head and neck cancer patients and impact of an early treatment decision on treatment. This study also aims to suggest recommendations to improve treatment compliance. METHODS: All new patients registered under the head and neck disease management group (DMG) over a period of 3 months at a single center were included. Their demographic details, time to treatment decision, and treatment compliance were determined. The findings were presented to head and neck DMG, and changes were implemented to patient workup with an aim to improve compliance. A reaudit was performed over a period of 3 months and results were compared. RESULTS: Two thousand two hundred and forty patients were included in the analysis. Patients with a treatment decision at 1-4 weeks stood at 28.32%, 63.88%, 80.8%, and 89.87%, respectively. Dropout rate was 26%. About 50% of patients planned for surgical intervention could be treated within the institution. After implementation of changes as recommended by DMG, 2418 patients were analyzed and findings were compared to the previous audit. The dropout rate reduced to 17.57%. The number of patients with a treatment decision at 1-4 weeks were 51.26%, 77.42%, 89.46%, and 94.31%, respectively. CONCLUSION: Early treatment decision and referral could significantly improve patient dropout and possibly compliance to treatment. Decentralization of cancer care is urgently needed to manage the high numbers of patients presenting to tertiary care centers. Setting up of new regional cancer centers and increasing infrastructure in the existing centers should be the long-term goals.

Reconstruction of Orbital Suprastructure Maxillectomy Defects by Temporalis Myofascial Flap.

Oncological surgery being radical is often mutilating in form and function especially in the maxillary/orbit region reconstruction of maxillo-orbit defects are challenging due to the complex three dimensional anatomy. Free flaps are de-rigueur but a technical resource with constraints. The temporalis myofascial flap (TMFF) is a locally available, safe and reliable flap which can be used for the reconstruction of various orbital and supramaxillary facial defects. To study the use of the temporalis myofascial flap in the reconstruction of various orbital and supramaxillary facial defects. Temporalis myofascial flap was harvested and successfully used in reconstruction of three patients who had undergone orbital exenteration with or without suprastructural maxillectomy. There was no morbidity related to flap loss. Temporalis flap (TMFF) can be considered as a first line reconstructive option for limited resection of upper maxilla with palatal preservation. Its proximity to the oral cavity, palate and mid third face and the technical ease makes the TMFF valuable for reconstruction. The techniques and outcomes of TMFF are discussed.

A randomized phase 3 trial comparing nimotuzumab plus cisplatin chemoradiotherapy versus cisplatin chemoradiotherapy alone in locally advanced head and neck cancer.

BACKGROUND: Because the addition of nimotuzumab to chemoradiation in patients with locally advanced head and neck cancer improved outcomes in a phase 2 study, the authors conducted a phase 3 study to confirm these findings. METHODS: This open-label, investigator-initiated, phase 3, randomized trial was conducted from 2012 to 2018. Adult patients with locally advanced head and neck cancer who were fit for radical chemoradiation were randomized 1:1 to receive either radical radiotherapy (66-70 grays) with concurrent weekly cisplatin (30 mg/m2 ) (CRT) or the same schedule of CRT with weekly nimotuzumab (200 mg) (NCRT).The primary endpoint was progression-free survival (PFS); key secondary endpoints were disease-free survival (DFS), duration of locoregional control (LRC), and overall survival (OS). An intent-to-treat analysis also was performed. RESULTS: In total, 536 patients were allocated equally to both treatment arms. The median follow-up was 39.13 months. The addition of nimotuzumab improved PFS (hazard ratio [HR], 0.69; 95% CI, 0.53-0.89; P = .004), LRC (HR, 0.67; 95% CI, 0.50-0.89; P = .006), and DFS (HR, 0.71; 95% CI, 0.55-0.92; P = .008) and had a trend toward improved OS (HR, 0.84; 95% CI, 0.65-1.08; P = .163). Grade 3 through 5 adverse events were similar between the 2 arms, except for a higher incidence of mucositis in the NCRT arm (66.7% vs 55.8%; P = .01). CONCLUSIONS: The addition of nimotuzumab to concurrent weekly CRT improves PFS, LRC, and DFS. This combination provides a novel alternative therapeutic option to a 3-weekly schedule of 100 mg/m2 cisplatin in patients with locally advanced head and neck cancer who are treated with radical-intent CRT.

Does the recurrent laryngeal nerve recover function after initial dysfunction in patients undergoing thyroidectomy?

OBJECTIVE: Total thyroidectomy with or without central compartment dissection is the treatment of choice for thyroid carcinoma. Extensive dissection along the recurrent laryngeal nerve (RLN) can lead to vocal cord fixity and hoarseness even without nerve sacrifice. Recovery rates after surgery for thyroid cancers have not been well documented. The aim of the study is to analyze the incidence of vocal cord palsy (VCP) and its recovery rates in patients operated for thyroid cancers. Methodology: We performed a retrospective study on prospectively collected data in 152 thyroidectomy patients with 254 RLNs at risk. All patients underwent a laryngoscopic examination to document vocal cord function in the immediate postoperative period and on subsequent follow-up. Incidence of VCP, recovery rates, univariate and multivariate analysis to identify risk factors for permanent VCP were calculated using binary logistic regression. RESULTS: In our study, 28% patients underwent redo surgeries and 74% patients had dissection of the central compartment. The immediate postoperative RLN palsy rate was 11.2%, with a palsy rate of 9% and 16.2% in the per primum and redo surgery cohorts. On follow-up, there was complete recovery of VCP in 66.7% of these nerves. The incidence of permanent RLN palsy was 3.9%. The mean time to recovery was 9.6 months. CONCLUSION: Vocal cord dysfunction recovered in most patients in this high-risk cohort. There was a significant recovery even in the redo surgery group and a policy of watchful waiting is recommended in the absence of severe symptoms. LEVEL OF EVIDENCE: III.

Once-a-Week Versus Once-Every-3-Weeks Cisplatin Chemoradiation for Locally Advanced Head and Neck Cancer: A Phase III Randomized Noninferiority Trial.

Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m2 resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m2, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Phosphaturic mesenchymal tumor of the nasal cavity and paranasal sinuses: A clinical curiosity presenting a diagnostic challenge.

Phosphaturic mesenchymal tumor (PMT) is a rare mesenchymal neoplasm associated with tumor-induced osteomalacia (TIO) and elevated serum FGF-23. Common in extremities, PMT rarely occurs in sinonasal region. We report a series of sinonasal PMT diagnosed at our institute over a 6-year period. Six cases of sinonasal PMT were identified during this period, of which five presented with features of TIO. Median age of patients was 45.5 years. All six tumors were composed of stellate to spindled cells, with prominent staghorn vasculature in four cases. Typical smudgy matrix was seen in all cases, but only focally; grungy calcification was absent. Accurate diagnosis of PMTs is imperative, as complete excision leads to dramatic resolution of TIO symptoms. Lack of knowledge of this entity prevents clinicians from ordering relevant investigations. Absence of specific morphological features, like grungy calcification, and presentation at atypical locations makes the diagnosis challenging. Awareness of this entity is essential in order to suspect PMT in patients presenting with a soft tissue mass and features of TIO, however unusual the location may be.
