Letter to the editor in reference to : "A web-based prediction score for head and neck cancer referrals"

Sir, We read with interest the article by Lau et al (2018) on the design of a web‐based prediction score for head and neck cancer (HNC) referrals. The authors state that there are no similar scoring systems available in the literature that are web‐based and applicable to the two‐week‐wait referrals. Over the last years, risk calculators for common cancer have been extensively explored and are available online, aiming to improve cancer referral pathways and detection.1, 2 A HNC risk calculator (HNC‐RC) based on symptoms and demographics has also been developed and is available online (Sensitivity: 74.8%; specificity: 65.9%; and overall predictive power (AUC): 0.77).3 It has also been externally validated maintaining its discriminatory ability (sensitivity: 79.3%; specificity: 68.6%; and AUC: 0.81). In their abstract, Lau et al have stated that logistic regression and artificial network machine approached have been used. Despite this, only the former was employed, as mentioned in their methodology section, due to time‐related restrictions and effort required to ensure an error‐free algorithm

A comparison of attitudes to laryngeal cancer treatment outcomes: a time trade-off study

Design: Time trade-off choice experiment. Setting: Two large head and neck cancer centres. Participants: Patients who have received treatment for head and neck cancer and members of the head and neck cancer multidisciplinary team. Main outcome measures: Participants were asked to rank the outcome scenarios, assign utility values using time trade-off and rate the importance of survival on treatment choice. Results: 49 head and neck cancer patients and 73 staff members were recruited. Chemoradiotherapy (CRT) optimal outcome was the most preferred health state (34/49, 69% patients and 50/73, 68% staff) and CRT with complications was least preferred (27/49 55% patients and 51/73 70% staff). Using time trade-off, mean utility values were calculated for CRT optimal outcome (0.73 for patients, 0.77 for staff), total laryngectomy (TL) optimal outcome (0.67 for patients, 0.69 for staff), TL outcome with complications (0.46 for patients, 0.51 for staff) and CRT with complications (0.36 for patients, 0.49 for staff). The average survival advantage required for a participant to change their preferred choice was 2.6 years. Conclusions: We have demonstrated that a significant proportion of head and neck cancer patients and staff members would not choose CRT to manage locally advanced laryngeal cancer. Staff members rated the health states associated with laryngeal cancer treatment higher than patients who have experienced them, and this is particularly evident when considering the poorer outcomes. The head and neck cancer community should develop methods of practice and decision making which incorporate elicitation and reporting of patient values as a central principle

Salvage carbon dioxide transoral laser microsurgery for laryngeal cancer after (chemo)radiotherapy : a European Laryngological Society consensus statement

Purpose To provide expert opinion and consensus on salvage carbon dioxide transoral laser microsurgery (CO2 TOLMS) for recurrent laryngeal squamous cell carcinoma (LSCC) after (chemo)radiotherapy [(C)RT]. Methods Expert members of the European Laryngological Society (ELS) Cancer and Dysplasia Committee were selected to create a dedicated panel on salvage CO2 TOLMS for LSCC. A series of statements regarding the critical aspects of decision-making were drafted, circulated, and modified or excluded in accordance with the Delphi process. Results The expert panel reached full consensus on 19 statements through a total of three sequential evaluation rounds. These statements were focused on different aspects of salvage CO2 TOLMS, with particular attention on preoperative diagnostic work-up, treatment indications, postoperative management, complications, functional outcomes, and follow-up. Conclusion Management of recurrent LSCC after (C)RT is challenging and is based on the need to find a balance between oncologic and functional outcomes. Salvage CO2 TOLMS is a minimally invasive approach that can be applied to selected patients with strict and careful indications. Herein, a series of statements based on an ELS expert consensus aimed at guiding the main aspects of CO2 TOLMS for LSCC in the salvage setting is presented.Peer reviewe

Transoral tongue base mucosectomy for the identification of the primary site in the work-up of cancers of unknown origin:systematic review and metaanalysis

The use of transoral robotic surgery (TORS) and laser microsurgery (TLM) in the diagnosis and identification of the site of the unknown primary has become increasingly common. This systematic review and meta-analysis aims to assess the use and efficacy of TORS and TLM for this indication. Systematic review and meta-analysis of studies employing TORS or TLM in diagnosis of the unknown primary tumor site in patients with cervical nodal metastases of squamous cell origin. MEDLINE, EMBASE and CINHAL were searched from inception to July 2018 for all studies that used TORS and or TLM in identifying the unknown primary. 251 studies were identified, of which 21 were eligible for inclusion. The primary tumour was identified by TORS/TLM in 78% of patients (433 out of 556). Tongue base mucosectomy (TBM) identified the primary in 222 of 427 cases (53%). In patients with negative physical examination, diagnostic imaging and PETCT, TBM identified the primary in 64% (95% CI 50, 79) cases. In patients who had negative CT/MRI imaging, negative PETCT and negative EUA and tonsillectomy, TBM identified a tongue base primary in 78% (95% CI 41, 92) cases. Haemorrhage, the commonest complication, was reported in 4.9% cases. Mean length of stay varied between 1.4 and 6.3 days. Tongue base mucosectomy, performed by TORS or TLM, is highly efficacious in identifying the unknown primary in the head and neck region

Background Local and/or regional recurrence and metachronous primary tumor arising in a previously irradiated area are rather frequent events in patients with head and neck squamous cell carcinoma (HNSCC). Re‐treatment is associated with an increased risk of serious toxicity and impaired quality of life (QOL) with an uncertain survival advantage. Methods We analyzed the literature on the efficacy and toxicity of photon/electron‐based external beam reirradiation for previously irradiated patients with HNSCC of non‐nasopharyngeal origin. Studies were grouped according to the radiotherapy technique used for reirradiation. Patient selection criteria, target volume identification method, tumor dose, fractionation schedule, systemic therapy administration, and toxicities were reviewed. Results In addition to disease‐related factors, current comorbidities and preexisting organ dysfunction must be considered when selecting patients for reirradiation. As morbidity from re‐treatment may be considerable and differ depending on which mode of re‐treatment is used, it is important to give patients information on potential morbidity outcomes so that an informed choice can be made within a shared decision‐making context. With improved dose distribution and adequate imaging support, including positron emission tomography‐CT, modern radiotherapy techniques may improve local control and reduce toxicity of reirradiation. A reirradiation dose of ≥60 Gy and a volume encompassing the gross tumor with up to a 5‐mm margin are recommended. Concomitant administration of systemic therapeutics and reirradiation is likely to be of similar benefit as observed in large randomized studies of upfront therapy. Conclusion Reirradiation, administered either with or without concurrent systemic therapy, is feasible and tolerable in properly selected patients with recurrent or a new primary tumor in a previously irradiated area of the head and neck, offering a meaningful survival (in the range of 10% to 30% at 2 years). Whenever feasible, salvage surgery is the method of choice for curative intent; patients at high‐risk for local recurrence should be advised that postoperative reirradiation is expected to increase locoregional control at the expense of higher toxicity and without survival advantage compared to salvage surgery without reirradiation. © 2014 Wiley Periodicals, Inc.

Long term survival following the detection of circulating tumour cells in head and neck squamous cell carcinoma

Background Techniques for detecting circulating tumor cells in the peripheral blood of patients with head and neck cancers may identify individuals likely to benefit from early systemic treatment. Methods Reconstruction experiments were used to optimise immunomagnetic enrichment and RT-PCR detection of circulating tumor cells using four markers (ELF3, CK19, EGFR and EphB4). This method was then tested in a pilot study using samples from 16 patients with advanced head and neck carcinomas. Results Seven patients were positive for circulating tumour cells both prior to and after surgery, 4 patients were positive prior to but not after surgery, 3 patients were positive after but not prior to surgery and 2 patients were negative. Two patients tested positive for circulating cells but there was no other evidence of tumor spread. Given this patient cohort had mostly advanced disease, as expected the detection of circulating tumour cells was not associated with significant differences in overall or disease free survival. Conclusion For the first time, we show that almost all patients with advanced head and neck cancers have circulating cells at the time of surgery. The clinical application of techniques for detection of spreading disease, such as the immunomagnetic enrichment RT-PCR analysis used in this study, should be explored further
