Incidence,timing, presentation,treatment, and outcomes of second primary head and neck squamous cell carcinoma after oral cancer

After their initial presentation of oral squamous cell carcinoma (SCC), patients have a lifelong risk of developing another new SCC of the head and neck. The aim of this study was to establish second primary rates, baseline characteristics (site, clinical or pathological stage, and smoking and alcohol history), timing, presentation, treatment, and outcomes. From the regional unit we analysed records of patients treated with curative intent for their first oral cancer between 2002 and 2007 inclusive. All patients had had at least 10 years of follow up either to death or the end of 2017. A total of 347 patients had been treated with curative intent, and of them, 29 had a second primary at a median (IQR) of 52 (30-79) months after the index operation. The incidence of developing a second primary tumour within two years was 1.7% (95% CI: 0.7% to 3.7%), within five years was 4.9% (95% CI: 2.9% to 7.7%), and within 10 years was 7.8% (95% CI: 5.1% to 11.1%). Early stage of first cancer was the only significant factor (p = 0.001) for development of a second primary within 10 years, reflecting survivorship. Most second primaries (21 patients) were staged as early, and by visual inspection. Most (n = 20) were within the oral cavity, one of which overlapped the oropharynx; eight others were in the oropharynx, and one in the larynx. Most patients (n = 22) were treated by operation with curative intent. Three were treated palliatively. Patients need to be aware of the risk of a second primary and, as most are in the mouth or oropharynx, there is a role for surveillance by primary dental care practitioners.     

Is routine holistic assessment with a prompt list feasible during consultations after treatment for oral cancer?

The head and neck cancer Patient Concerns Inventory (PCI-HN) is a holistic, self-reported list of items that can help patients to disclose their needs and concerns during routine follow-up consultations. The aim of this study was to report how often it was used during the first three years of follow up after treatment for oral cancer, and the range of issues that were raised. The sample comprised consecutive patients treated over a three-year period with curative intent. All clinic attendances were reviewed until October 2015 or until patients had a recurrence, a subsequent primary, metastases, or were discharged home or to follow up at a peripheral hospital, or started palliative care. We identified 92 patients and data were available for 88 of them. The median (IQR) age at the time of treatment was 65 (57-76) years, and 48 (55%) were men. Reviews alternated between the surgeon and oncologist, and typically there were 4.4 surgical reviews in year one, 2.8 in year two, and 1.6 in year three. The inventory was completed 157 times; at least once by 71% (55/77) during year one, 57% (29/51) during year two, and 37% (13/35) during year three. Of those who completed none, nearly half (7/17) died within 12 months, and another six were over 80 years of age. In conclusion, the diversity of concerns raised by patients highlights the need for holistic assessment during follow up, and integration of the inventory into routine consultations will mean that we can repeat it.     

Second primary head and neck squamous cell cancers with aggressive behavior in patients with chronic myeloid leukaemia

Patients with chronic myeloid leukaemia (CML) are at considerable risk of developing second primary neoplasms. However, mucosal squamous cell cancers (SCCs) of the head and neck have not been reported. We review the data of 7 patients with mucosal SCC of the head and neck that presented as metachronous second primary tumours in patients with CML. All 7 patients were men (median age 48 years, range 31-67) (site:oral cavity n=6, hypopharynx n=1). The median interval between diagnosis of CML and head neck cancer was 6 years (range 2-15). Treatment was curative in 4 and palliative in 3. At median follow up of 14 months (range 2-44), 3 patients had died of head and neck cancer, 1 of CML, and 3 were alive and free of disease. Mucosal cancers of the head and neck can occur in long-term survivors of CML. They are aggressive and tend to recur.     

Planned neck dissection after chemoradiotherapy in advanced oropharyngeal squamous cell cancer: The role of US,MRI and FDG-PET/TC scans to assess residual neck disease

ObjectiveTo investigate the ability of neck ultrasounds (US), magnetic resonance imaging (MRI) and positron emission tomography (FDG-PET/TC) in detecting residual nodal disease after chemoradiotherapy in patients with advanced oropharyngeal squamous cell carcinoma (OPSCC).MethodsFrom 2006 to 2009, 36 consecutive patients affected by OPSCC with bulky nodal disease (>3 cm), treated with primary concurrent chemoradiotherapy, were enrolled prospectively. Nodal response to treatment was assessed by using US, MRI and FDG-PET/CT. Planned neck dissection (ND) was performed in all the patients, and the histopathological node status was compared to the imaging findings in order to establish sensitivity, specificity, accuracy and predictive values of each technique.ResultsMetastatic disease was assessed in 18/37 (48.6%) hemi-necks, always localized in levels II–IV. US showed greater sensitivity (77.8%) and, combined with FDG-PET/TC, produced the highest negative predictive value (93.3%). US, MRI and FDG-PET/TC scans showed the highest specificity (100%), accuracy (93.8%) and positive predictive values (100%).ConclusionsIn the presence of advanced OPSCC with bulky nodal disease, US combined with FDG-PET/TC could be a reliable and cost-effective strategy to identify patients with complete nodal response to chemoradiotherapy that might not require post-treatment ND but only observation. When residual disease in the neck was detected, selective ND was recommended.     

Oral and oropharyngeal cancer in the West of Scotland—long-term outcome data of a prospective audit 1999-2001

We prospectively studied patients from the west of Scotland who presented with a primary cancer of the oral cavity or oropharynx over a period of 24 months from November 1999, and report long-term outcomes and prognostic factors. A total of 481 patients had squamous cell carcinoma (SCC), 5-year disease-specific survival (DSS) was 50%, and overall survival (OS) was 35%. One hundred were not suitable for treatment with curative intent, and factors other than stage were important in this decision. Of those treated with curative intent, 249 had SCC of the oral cavity (5-year DSS 67%; OS 42%), and 132 had SCC of the oropharynx (5-year DSS 62%; OS 42%). Multivariate analysis showed that pathological nodal stage (p = 0.051, 95% CI 0.998-1.955), and perineural invasion (p = 0.001, 95% CI 0.186-0.666) were prognostic indicators. Improved results using intensive treatment protocols that have been seen in trials are not likely to translate directly into a general population of patients with head and neck cancer. Algorithms that allow several pathological prognostic indicators to be incorporated into decisions about adjuvant treatment should be used.     

Real-time magnetic resonance imaging: mechanics of oral and facial function

We report a summary of developmental work to explore, develop, and establish clinical applications of real-time magnetic resonance imaging (rtMRI) with a temporal resolution of 70 frames/second in oral and maxillofacial surgery (OMFS). Real-time MRI can contribute to procedure planning, diagnostics, rehabilitation, monitoring, and patient education. At present, conventional MRI is used extensively in the diagnosis, staging, and follow up of head and neck cancer patients, with scanning durations typically of several minutes and temporal resolution of up to 0.5 frames/second. The potential for rtMRI, where function can be assessed, could go far beyond the established clinical application of conventional MRI. Preliminary prototyping is a first stage in the establishment of rtMRI in OMFS. We follow best-practice approaches in co-creation across multiple disciplines, an indispensable aspect in the development of new methodologies and diagnostic tools.     

What patients consider important: Temporal variations by early and late stage oral,oropharyngeal and laryngeal subsites

Functional outcomes are of high priority to cancer patients and are relevant when considering treatment strategies. This study aimed to collate and analyse importance rankings of UW-QOL over time for patients treated with curative intent for primary head and neck squamous cell carcinoma between 2000 and 2010, and to compare early and late stage oral, oropharyngeal and laryngeal subsites. There were 1614 patients comprising oral cavity 47% (751), oropharyngeal 24% (382), laryngeal 20% (320) and other HNC locations 10% (161). Items of importance remained relatively stable within clinical groups but there were notable differences between groups. For patients with early oral tumours no domain was especially dominant, whereas for late oral tumours swallowing, chewing, speech and saliva were selected more often. Swallowing and saliva were more important in oropharyngeal tumours, as was taste with more advanced oropharyngeal tumours. Speech and activity were important for those with early laryngeal tumours, as were swallowing and speech for more advanced laryngeal tumours. Swallowing and saliva were more important in advanced tumours for all sites. This data confirms the priority patients place on swallowing, chewing, speech, and saliva, therefore curative treatments should optimise these functions wherever possible and provide access to post-treatment interventions as required.

Implications of the Quality of Life Metric in head and neck cancer

Across England the NHS (National Health Service) has set in place a national survey that invites cancer patients to report their quality of life around 18 months after their diagnosis. The two questionnaires are the EQ-5D-5L and EORTC C30. For head and neck cancer (HNC) several factors will affect patients’ characteristics and response rates at the 18-month window. There were three aims of this study: to account for drop-out over the first 18 months, to report the characteristics of responders in comparison with the whole cohort, and to summarise the health-related quality of life (HRQoL) outcomes (EQ-5D-5L and EORTC QLQ-C30). Patients treated with curative intent who were cancer-free at 15 months were sent a postal survey 16 months after diagnosis, with a second reminder at 18 months. Of the 256 patients analysed, 187 were alive at the 15-month follow-up window, 20 of whom were living with recurrence. Survival was related to tumour stage, treatment intent, and mode of treatment. A total of 109 (67%) responded and the response rate was better from older patients. Older patients reported better HRQoL across all measures apart from EQ-5D-5L mobility and EORTC physical functioning, while patients living in more deprived neighbourhoods reported worse HRQoL across all measures apart from loss of appetite. Other than a tendency for a worse HRQoL in patients having surgery with free-flap transfer, there were no obvious consistent differences by tumour stage, site, or treatment. In conclusion, when reflecting on the findings of the National QoL Metric (QoLM) in HNC, it will be important to consider the influence of survivorship and response rates.     

ASA grade and disease-free mortality in head and neck cancer patients: A prospective study

Complex surgery with curative intent as part of the care of patients with head and neck cancer, who also have serious coexisting conditions is sometimes viewed critically as being unduly, optimistic. We have used American Society of Anesthesiologists’ (ASA) grading by a single anaesthetist prospectively as a baseline to investigate a possible link between coexisiting conditions and disease-free survival in 114 patients with head and neck cancer patients treated by the same anaesthetist and surgical team, and found that the ASA grade is not a reliable predictor of disease-free survival. There was no significant association between ASA grade and overall mortality, but there was a significant association between ASA grade and mortality associated with metastatic disease. However, the test for trend was not significant, which suggested that deaths from metastatic disease did not increase in line with ASA grading. All patients in ASA grades II and III were alive 2 years after their initial operation and the risk of mortality after 2 years may increase by up to 10%.

Role of tonsillectomy in the search for a squamous cell carcinoma from an unknown primary in the head and neck

Cervical metastases of an unknown primary lesion accounts for 5%-10% of head and neck cancers. Tonsillar carcinoma is the third most common, with an incidence in the region of 18%-47% of unknown primaries, and the likelihood of synchronous tonsillar tumour of about 5%-10%. Current practice for investigating an unknown primary includes computed tomography (CT) with or without magnetic resonance imaging (MRI), and then, if necessary, 18-fluoro-deoxy-glucose positron emission tomography (FDG-PET). This is followed by panendoscopy with biopsy from the potential primary sites and tonsillectomy. A five-year retrospective review of our database of metastatic squamous cell carcinomas from unknown primary sites identified patients with synchronous tonsillar tumours (n=5). All had clinically normal-looking tonsils; MRI was within normal limit and a PET-CT identified the ipsilateral tonsillar primary in three cases only. Bilateral tonsillectomy rather than a tonsillar biopsy in the search for an unknown primary has been standard practice in our unit. Identification of a second primary dictates planning for the primary site and in the long term, influences patients' survival. We therefore recommend that bilateral tonsillectomy should be standard in the investigation of patients who present with cervical metastases from an unknown primary in the head and neck region.     

Primary head and neck mucosal melanoma: Predictors of survival and a case series on sentinel node biopsy

IntroductionHead and neck mucosal melanoma (HNMM) is a rare tumor with a poor outcome. The objective of this study was to assess outcome and prognostic factors for a cohort of patients treated in a head and neck cancer center. In addition, a case series on sentinel lymph node biopsy (SLNB) was included to evaluate it as a method for staging the node-negative neck.MethodsA retrospective study design was chosen, and 50 patients who were treated from 1973 to 2015 in our institution for primary HNMM were included. The Kaplan–Meier method was used to estimate survival rates. Uni- and multivariate analyses were used to study the influence of possible risk factors on the patients' outcome. These risk factors included patient demographics, tumor characteristics, and treatment modalities.ResultsAll patients were treated surgically and 50% received adjuvant treatment. The median disease specific survival (DSS) was 38 months, with a 5-year survival rate of 44%. Positive surgical margin (p = 0.004) and distant failure (p = 0.005) were associated with a worse DSS. The median disease-free survival (DFS) was 27 months, with a 5-year disease-free rate of 12%. Only tumor depth >5 mm (p = 0.002) was associated with a worse DFS. Five clinically node-negative patients received SLNB and only the two SLN-positive individuals suffered from distant failure. Radiotherapy, chemotherapy, and AJCC/UICC stage had no influence on any outcome measure.ConclusionsPositive surgical margin and distant failure are the only independent prognostic factors for DSS. Tumor depth can predict distant failure. SLNB may be a valuable staging tool for the node-negative neck.     

The application of magnetic resonance imaging-guided fine-needle aspiration cytology in the diagnosis of deep lesions in the head and neck.

PURPOSE: Image-guided fine-needle aspiration cytology (FNAC) may be useful as an alternative diagnostic approach to lesions in the head and neck. This study reports on the use of magnetic resonance imaging (MRI)-guided FNAC for diagnostic evaluation of deep lesions in this region. MATERIALS AND METHODS: This was a prospective study of 12 patients with deep lesions in the head and neck who underwent MRI-guided FNAC at the Shanghai 9th People's Hospital. A 0.2-T open magnet was used for MRI and localization of the 20-gauge MRI-compatible needle. All of the aspirated samples were stained with hematoxylin and eosin and examined by a cytopathologist. RESULTS: The needle in all 12 cases was displayed on MRI in the central portion of the lesion under the guidance of MRI; 12 of 12 patients (100%) had diagnostic aspirations and none needed open biopsy for more specific histologic interpretation. Six of these 12 patients with tumors (4 malignant, 2 benign) underwent operative treatment with positive postoperative pathologic results. One patient had a diagnosis of inflammation. The diagnostic accuracy was 91.67% (11 of 12), the sensitivity was 85.71% (6 of 7), and the specificity was 100% (5 of 5). There were no false-positive results and 1 false-negative result, for a false-negative rate of 14.29% (1 of 7). All aspiration procedures were well tolerated and without complications. CONCLUSIONS: MRI-guided FNAC is a cost-effective tool for establishing tissue diagnosis as a primary investigative modality. It is helpful and accurate in the diagnosis of deep lesions in the head and neck and in follow-up of patients, thereby avoiding further surgical intervention.

Dental management of low socioeconomic level patients before radiotherapy of the head and neck with special emphasis on the prevention of osteoradionecrosis

Head and neck cancer patients need to receive dental care previously to radiotherapy. Even patients who regularly visit dental offices need special attention including prophylactic and curative treatments. The purposes of this study were to evaluate the dental status of Brazilian head and neck squamous cell carcinoma patients with low socioeconomic level as well as to discuss the dental treatment performed and the oral side effects of radiotherapy. Forty patients with head and neck squamous cell carcinoma received dental care and dental extractions prior to radiotherapy and were were followed up for a mean period of 28.7 months after the cancer treatment. Before radiotherapy, 28 patients were dentulous and 12 edentulous, and all of them had poor oral health and hygiene. The most common treatment performed were dental extraction and 23 patients had 8.6 teeth extracted on average. One out of 9 (11.1%) patients developed radiation caries and 5 out of 23 cases (21.3% - Group I) developed osteoradionecrosis, being only 1 case associated with previous dental extraction. Brazilian low-socioeconomic level patients with head and neck cancer were submitted to multiple dental extractions due to poor dental conditions and inadequate oral care. The dental treatment did not prevent osteoradionecrosis, which presumably presented a multifactorial etiology in most cases.

MRI scanning and orthodontics

Abstract

Magnetic Resonance Imaging (MRI) plays an important role in diagnosis for many head and neck lesions. Both clinical and experimental studies have shown that orthodontic appliances may produce image distortion on MRI scans of the head and neck. A case is presented in which the patient complained of unexplained right-sided facial paraesthesia, whilst undergoing fixed appliance orthodontic treatment. This was a serious symptom, which warranted investigation including a MRI scan. The compatibility of fixed appliances with MRI is discussed.
