Algorithms of follow-up in patients with head and neck cancer in relation to primary location and advancement. Consensus of Polish ENT Society Board and Head Neck Experts. Front Oncol 2023; 13:1298541. [PMID: 38152365 PMCID: PMC10751934 DOI: 10.3389/fonc.2023.1298541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 10/31/2023] [Indexed: 12/29/2023] Open
Abstract
Summary The algorithm of follow-up in patients with head and neck cancer (HNC) has been prepared by a board of Polish Head Neck and Oncology Experts. The aim of this research is to focus on the specificity of HNC monitoring, to review the current trends in follow-up, and to adapt the evidence-based medicine international standards to the capabilities of the local healthcare service. Materials and methods The first methodological step was to categorize HNCs according to the estimated risk of failure after the adequate first-line treatment and according to the possibility of effective salvage treatment, resulting in improved overall survival. The final method used in this work was to prepare an authors' original monitoring algorithm for HNC groups with a high, moderate, and low risk of recurrence in combination with a high or low probability of using an effective salvage. Results Four categories were established: Ia. low risk of recurrence + effective organ preservation feasible; Ib. low risk of recurrence + effective salvage feasible; II. moderate risk of recurrence + effective salvage feasible; III. high risk of recurrence + effective salvage feasible; and IV. high risk of recurrence + no effective salvage feasible. Follow-up visit consisting of 1. ENT examination + neck ultrasound, 2. imaging HN tests, 3. chest imaging, 4. blood tests, and 5. rehabilitation (speech and swallowing) was scheduled with a very different frequency, at the proposed monthly intervals, tailored to the needs of the group. The number of visits for individual groups varies from 1 to 8 in the first 2 years and from 1 to 17 in the entire 5-year monitoring period. Group IV has not been included in regular follow-up, visits on own initiative of the patient if symptomatic, or supportive care needs, having in mind that third-line therapy and immune checkpoint inhibitors are available. Conclusion Universal monitoring algorithm for HNC four groups with a high, moderate, and low risk of recurrence after the adequate treatment in combination with a high or low probability of using an effective salvage is an innovative approach to redeploying system resources and ensuring maximum benefit for patients with HNC.

Novel approach to reduce SARS-CoV-2 transmission during trans-oral robotic surgery. J Robot Surg 2021; 15:963-970. [PMID: 33547981 PMCID: PMC7866962 DOI: 10.1007/s11701-021-01200-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Accepted: 01/17/2021] [Indexed: 11/10/2022]
Abstract
This study describes a novel approach in the reduction of SARS-CoV-2 transmission during trans-oral robotic surgery (TORS). Eight patients underwent TORS between 01 February 2020 and 07 September 2020. A sterile plastic sheet draped over sterile supports with water-tight seal around each cannula was used to create a sterile working space within which the robotic arms could freely move during operation. This set-up acts as an additional physical barrier against droplet and aerosol transmission. Operative diagnosis; droplet count and distribution on plastic sheet and face shields of console and assistant surgeons, and scrub nurse were documented. TORS tumour excision was performed for patients with suspected tonsillar tumour (n = 3) and tongue base tumour (n = 2). TORS tonsillectomy and tongue base mucosectomy was performed for cervical nodal metastatic carcinoma of unknown origin (n = 3). Droplet contamination was noted on all plastic drapes (n = 8). Droplet contamination was most severe over the central surface at 97.2% (91.7–100.0%), with the highest droplet count along the centre-most column where it overlies the site of operation in the oral cavity 33.3% (n = 31). Droplet count decreased towards the periphery. Contamination rate was 2.8% (0.0–8.3%) over the right lateral surface. There was no droplet contamination over the vertex and left lateral surface of plastic drapes. No droplet contamination was noted on face shields of all parties. The use of sterile plastic drapes with water-tight seal around each robotic cannula can help reduce viral transmission to healthcare providers during TORS.

Abstract
Simple Summary Options for the curative treatment of locally recurrent nasopharyngeal carcinoma include surgery or re-irradiation. Both approaches have been scientifically explored, yet there is no consensus on the indication or definitive preference of the above two salvage treatments. The aim of this review is to summarize the current evidence on the local treatment of recurrent nasopharyngeal carcinoma. The feasibility, safety, and efficacy of salvage surgery and radical re-irradiation are discussed. Recommendations on treatment modifications during the coronavirus disease 2019 pandemic are included as well. Abstract Recurrent nasopharyngeal carcinoma represents an extremely challenging therapeutic situation. Given the vulnerability of the already pretreated neurological structures surrounding the nasopharynx, any potential salvage retreatment option bears a significant risk of severe complications that result in high treatment-related morbidity, quality of life deterioration, and even mortality. Yet, with careful patient selection, long-term survival may be achieved after local retreatment in a subgroup of patients with local or regional relapse of nasopharyngeal cancer. Early detection of the recurrence represents the key to therapeutic success, and in the case of early stage disease, several curative treatment options can be offered to the patient, albeit with minimal support in prospective clinical data. In this article, an up-to-date review of published evidence on modern surgical and radiation therapy treatment options is summarized, including currently recommended treatment modifications of both therapeutic approaches during the coronavirus disease 2019 pandemic.

Comparing endoscopic surgeries with open surgeries in terms of effectiveness and safety in salvaging residual or recurrent nasopharyngeal cancer: Systematic review and meta-analysis. Head Neck 2020; 42:3415-3426.

Abstract
Consensus has yet to be reached on the optimal operation for patients with residual or recurrent nasopharyngeal carcinoma (NPC). To compare effectiveness and safety of open surgery and endoscopic surgery for patients with residual or recurrent NPC. Pubmed, Embase, and Cochrane were searched for relevant publications from January 1, 2000 to May 1, 2017. Included studies reported specific residual or local recurrent nasopharyngeal cancer survival data. Proportional meta-analysis was performed on both outcomes with a random-effects model, and the 95% confidential intervals were calculated by Stata 12.0 software. For patients with different tumor classification, a downward trend of 2-year overall survival (OS) was observed for both surgical populations. Endoscopic surgeries achieved bigger rates than open surgeries in patients with recurrent tumor (rT) 1, rT2, and rT3 (93% vs 87%, 77% vs 63%, 67% vs 53%). As for patients with rT4, 2-year OS was similar (35% vs 35%).In addition, the former is less severe complications, lower local recurrence rates (27% vs 32%). Our study found that, compared to open surgery, endoscopic surgery was a safer and more effective treatment modality in managing patients with recurrent or residual NPC.

Abstract
OBJECTIVES To develop and validate a nomogram to predict survival in patients with recurrent nasopharyngeal carcinoma (NPC) after salvage endoscopic surgery. MATERIALS AND METHODS A total of 229 eligible patients with recurrent NPC were divided into training (n = 115) and validation (n = 114) cohorts. A multivariate Cox proportional risk regression model was used to identify significant prognostic factors for overall survival (OS) in the training cohort. A nomogram was then developed based on the regression model. The performance of the nomogram was assessed with regard to discrimination and calibration. Patients were divided into low-risk or high-risk groups based on the risk scores derived from the nomogram. Furthermore, decision curve analysis (DCA) was used to assess the clinical utility of the nomogram. RESULTS Six significant predictors were identified: diabetes mellitus, body mass index (BMI), neutrophil-to-lymphocyte ratio (NLR), T stage, lymph node metastasis, and tumor necrosis. The nomogram incorporating these six predictors demonstrated favorable discrimination and calibration in the training cohort, with a C-index of 0.746 (95% confidence interval [CI] 0.656-0.836), which was subsequently confirmed in the validation cohort (C-index 0.768 [95% CI 0.675-0.861]). Furthermore, the nomogram successfully distinguished patients into low- and high-risk groups. DCA indicated that the nomogram was clinically useful. CONCLUSIONS The novel nomogram demonstrated its potential as an individual tool to predict survival in patients with recurrent NPC after salvage endoscopic surgery.

Abstract
Nasopharyngeal carcinoma is endemic in southern parts of China including Hong Kong. Primary treatment entails radiotherapy ± chemotherapy depending on disease stage at presentation. Surgery is offered as a means of salvage for persistent and recurrent disease. Comprehensive preoperative work-up, careful patient selection, attention to details perioperation and multidisciplinary approach is essential in ensuring optimal outcomes after salvage surgery for recurrent nasopharyngeal carcinoma patients. Since the COVID-19 outbreak, we are faced with unprecedented challenges with priorities of care and resources being shifted to combat the virus. These include patient selection and timing of treatment, while preventing disease transmission to heath care providers. Practices and recommendations made in this document are intended to support safe clinical practice and efficient use of resources during this challenging time.

Abstract
Multiple anterior surgical approaches are available to obtain access to the nasopharynx, clivus, and craniocervical junction. These include the direct and transoral robotic surgery transpalatal, maxillary swing, and endoscopic endonasal approaches. In this article, we describe the indications for these techniques, surgical steps, and associated morbidities. This article is a PubMed literature review. A review of the literature was conducted to assess the techniques, surgical steps, and associated morbidities with transpalatal approaches to the skull base and nasopharynx. The transpalatal approach has been traditionally utilized to obtain surgical access to the nasopharynx, clivus, and craniocervical junction. Morbidity includes velopalatine insufficiency due to shortening of the soft palate from scar contraction or neuromuscular damage, thus leading to hypernasal speech and dysphagia. Middle ear effusion and oronasal or oronasopharyngeal palatal fistula are additional potential morbidities. The choice of surgical approach depends on a variety of factors including the disease location and extent, surgeon experience, and available resources.

Abstract
AIM Endoscopic endonasal nasopharyngectomy (EEN) for recurrent nasopharyngeal carcinoma (rNPC) is being increasingly used due to the added high magnification, reduced morbidities associated with open procedures and good survival outcomes. Most studies looked at usage of EEN in patients with lower recurrent staging (rT1 and rT2) although more and more surgeons are studying the outcome of EEN in advanced rNPC (rT3 and rT4). The aims of this study were to report the long-term 5-year survival outcome of EEN performed in patients with advanced rNPC, and to determine any prognostic factors for patients' survival. METHODS All patients who underwent EEN for advanced rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah. We reported the 5-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors. RESULTS Twelve patients with rNPC (2 rT3 and 10 rT4) were followed-up over a mean duration of 44.8 months (range, 40-440 weeks). The 5-year OS was 50.0% (mean 44.75 months), DFS was 25.0% (mean 35.25 months) and the DSS was 58.3% (mean 43.33 months). No severe operative complications were encountered and no independent prognostic factors for survival outcome were identified. CONCLUSION This is the first report in English that exclusively described the long-term 5-year survival data in patients with both rT3 and rT4 recurrent NPC after EEN. The data suggest that EEN is a feasible treatment to improve survival with minimal morbidities in patients with rT3 and rT4 recurrent NPC. However, more studies with larger patient size is recommended.

Abstract
Objectives: The indication of transoral robotic surgery for hypopharyngeal cancer is limited because of poor accessibility. The aim of this study was to explore the efficacy of a curved laryngopharyngoscope used in combination with a next-generation flexible robotic surgical system for accessing and resecting the hypopharynx. Methods: A comparative evaluation of the curved laryngopharyngoscope versus standard straight-blade retractors using the flexible robotic surgical system was conducted on 2 cadavers. End points measured included visualization, accessibility, and ease of dissection for accessing and resecting the hypopharynx. Results: Visualization, accessibility, and dissection were superior with the curved laryngopharyngoscope in all subareas of the hypopharynx. The advantages of accessibility and visualization were much more evident in the cadaver with a high body mass index. Conclusions: These preclinical data suggest that using a curved laryngopharyngoscope in combination with a flexible robotic surgical system may lead to technical innovations concerning transoral surgery of the hypopharynx.

Abstract
Abstract The highest incidence of nasopharyngeal carcinoma (NPC) is in southeast China, including Taiwan. Many side effects have been observed following radiation therapy with chemotherapy; hence, exploring new treatment modalities for NPC is an important future direction. Angiotensin-(1–7) [Ang-(1–7)] is an endogenous heptapeptide hormone and important component of the renin–angiotensin system that acts through both the Mas receptor and AT2 receptor, exhibiting anti-proliferative and anti-angiogenic properties in cancer cells. However, the anti-cancer activity of Ang-(1–7) related to autophagy in NPC remains largely debated. The effects and signaling pathway(s) involved in the Ang-(1–7)/Mas receptor axis in NPC were investigated both in vitro and in vivo. Ang-(1–7) inhibited cell proliferation, migration, and invasion in NPC-TW01 cells. Ang-(1–7) induced autophagy by increasing the levels of the autophagy marker LC3-II and by enhancing p62 degradation via activation of the Beclin-1/Bcl-2 signaling pathway with involvement of the PI3K/Akt/mTOR and p38 pathways in vitro study. In addition, pre-treatment with Ang-(1–7) inhibited tumor growth in NPC xenografts by inducing autophagy, suggesting a correlation between PI3K/Akt/mTOR pathway inhibition and the abovementioned anti-cancer activities. However, no autophagy was observed following Ang-(1–7) post-treatment. Taken together, these data indicate that Ang-(1–7) plays a novel role in autophagy downstream signaling pathways in NPC, supporting its potential as a therapeutic agent for alleviation the incidence of NPC and preventive treatment of recurrent NPC. Key messages Ang-(1–7) inhibits cell proliferation, migration, and invasion by activating autophagy Ang-(1–7)pre-treatment inhibits tumor growth via autophagy by suppressing PI3K/Akt/mTOR pathway. Ang-(1–7) may provide a novel preventative treatment for NPC and recurrent NPC

Abstract
BACKGROUND The purpose of this study was to present our experience with retropharyngeal node reirradiation using highly conformal radiotherapy (RT). METHODS A retrospective screen of 2504 consecutively irradiated patients with head and neck malignancies between 2005 and 2015 identified 19 patients who underwent reirradiation for retropharyngeal node metastasis. Clinical and toxicity outcomes were assessed in these patients. RESULTS Thirteen patients (68%) had squamous cell carcinoma. Eleven patients (58%) received conventionally fractionated intensity-modulated radiotherapy (IMRT) or proton therapy, and 8 patients (42%) received single-fractionated or hypofractionated stereotactic RT. Fourteen patients (74%) received chemotherapy. Median follow-up was 14.7 months. The 1-year local control, locoregional control, overall survival, and progression-free survival rates were 100%, 94%, 92%, and 92%, respectively. Three patients (16%) experienced acute grade 3 toxicity and occurred in those treated with IMRT. There was no late grade ≥3 toxicity. CONCLUSION Retropharyngeal node reirradiation with conformal therapy is well tolerated and associated with excellent short-term disease control.

Eur Arch Otorhinolaryngol 2016; 274:275-281. [PMID: 27520568 DOI: 10.1007/s00405-016-4248-2] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Accepted: 08/05/2016] [Indexed: 11/30/2022]
Abstract
Endoscopic endonasal nasopharyngectomy (EEN) has become increasingly used for recurrent nasopharyngeal carcinoma (rNPC) due to reduced functional and cosmetic morbidities compared to conventional external approach. Majority of the existing studies on EEN focused on patients with lower recurrent staging of rT1 and rT2. The aims of this study were to provide a preliminary report on the outcome of EEN performed in patients with advanced (rT3 and rT4) rNPC, and to determine the prognostic factors for patients' survival. All patients who underwent EEN for rNPC between January 2003 and December 2015 inclusive were analyzed. All surgeries were performed in University Malaya Medical Centre in Kuala Lumpur and Queen Elizabeth Hospital in Sabah, by a single surgeon. We reported the 2-year overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS) and any related complications and significant prognostic factors. Fifteen patients with recurrent NPC (2 rT3 and 13 rT4 tumours) underwent EEN over the 13 years period. The mean age was 50.4 years (range 30-65) and the mean follow-up period was 28.7 months (range 9-81 weeks). The 2-year OS, DFS and DSS were 66.7 % (mean 19.4 months), 40 % (mean 15.7 months) and 73.3 % (mean 20.2 months), respectively. No severe operative complications were encountered. No independent prognostic factors for survival outcome were identified. This is the first preliminary report in English that exclusively looked at the use of EEN in advanced rT3 and rT4 NPCs, showing favourable patient outcome. However, further long-term follow-up of patients is required.
