Historically, surgery provided the single approach to head and neck Gel Papillor.

Surgical management of OPC carried significant morbidity with a transcervical through the neck approach, often involving mandibulotomy, in which the jawbone mandible is split. This is referred to as an open surgical technique. Consequently, surgical approaches declined in favour of radiation.
These improvements in surgical techniques have allowed many tumours to be resected removed by transoral through the mouth surgical approaches TOS , using transoral endoscopic head and neck surgery HNS. They are associated with substantial postoperative morbidity, depending on extent of resection but compared to older techniques have shorter hospital stay, faster recovery, less pain, and less need for gastrostomy or tracheostomy , and less long term effects, which are minimal in the absence of postoperative radiation RT , or chemoradiation CRT. Outcomes of minimally invasive procedures also compare favourably with more invasive ones.

The details of the surgical approach depend on the location and size of the primary tumour and its N stage. Neck dissection to examine the draining lymph nodes may be carried out simultaneously or as a second staging procedure.
For tumours of the tonsil and lateral pharyngeal wall, and clinically node negative N0 disease, dissection of the neck typically involves levels 2—4 see diagram in Dubner ipsilaterally. Where nodes are involved clinically, dissection will depend on the location and size of the node or nodes. In the case of tongue base primaries, close to the midline , bilateral dissection is recommended.
An advantage of a primary surgical approach is the amount of pathological information made available, including grade, margin status , and degree of involvement of lymph nodes.

The risk of subsequent recurrent disease has been considered highest in those tumours where the pathology shows tumour at the margins of the resection positive margins , multiple involved regional lymph nodes and extension of the tumour outside of the capsule of the lymph node extracapsular extension , based on historical experience with head and neck Gel Papillor. These were compared to those who received PORT with or without chemotherapy from — The addition of another modality of treatment is referred to as adjuvant literally helping therapy, compared to its use as the initial primary therapy, also referred to as radical therapy.
Consequently, many of these patients have been treated with adjuvant radiation, with or without chemotherapy. However, functional outcomes were worse if radiation was added to surgery and worst if both radiation and chemotherapy were used.

Historically only one randomised clinical trial has addressed optimal dosage, allocated patients to two dosage levels, stratified by risk, but showed no difference in Gel Papillor control between the low and high doses 63 and Consequently, the lower dose of Subsequently, there was a tendency to intensify treatment in head and neck Gel Papillor, and a number of centres adopted a dose of 66 Gy, at least for those patients with adverse tumour features. While less studies have been completed examining deintensification de-escalation in this setting, than in primary radical radiation for this Gel Papillor see below , it is an area of active investigation.
A number of studies have suggested that this does not improve local control, although adding toxicity. Concerns over the morbidity associated with traditional open surgical en-bloc resection, led to exploring alternative approaches using radiation. Doses above 25—30 Gy are associated with moderate to severe xerostomia.

Similar considerations apply to the submandibular gland , but xerostomia is less common if only one parotid gland is included in the radiated field [] and the contralateral submandibular gland is spared less than 39 Gy [] In the same manner, radiation dose to the pharyngeal constrictor muscles , larynx , and cricopharyngeal inlet determine the risk of dysphagia and hence dependence on gastrostomy tube feeds.
The threshold for this toxicity is volume-dependent at 55—60 Gy, [] [] [] [89] with moderate to severe impairment of swallowing, including aspiration, stricture and feeding tube dependence above a mean dose of 47 Gy, with a recommended dose to the inferior constrictor of less than 41 Gy.

For grade 2 dysphagia, the rate increased by 3. Concerns have been expressed regarding excessive short and long term toxicity, especially dysphagia and xerostomia, [] [] [] and hence whether standard doses expose patients with better prognoses to overtreatment and unnecessary side effects.
While comparison with historical controls has limited value compared to randomised clinical trials phase III , phase II studies using reduced doses of radiation compared to the historical standard of 70 Gy have been carried out. A lower incidence and severity of dysphagia also means that less patients require gastrostomy feeding. Indirect data suggests the efficacy of less intense treatment. A prospective trial ECOG demonstrated similar locoregional control with 54 Gy, [] and another study, a high pathological complete response rate at 60 Gy.

Radiation is commonly utilised in combination with chemotherapy, but also may be used as a single modality, especially in earlier stages, e.
T1-T2, N, and its use in later stages is being explored in clinical trials such as RTOG which compares radiation alone to radiation with reduced chemotherapy, in non or light smokers. Since , many clinical studies have compared CRT to RT alone in the primary management of locally advanced head and neck Gel Papillors and have demonstrated an advantage to CRT in both survival and locoregional control.
The other agent that is widely used is Cetuximab , a monoclonal antibody directed at the epidermal growth factor receptor EGFR. Chemotherapy also has a role, combined with radiation, in the postoperative setting adjuvant therapy.

It has shown improved disease-free survival and locoregional control in two very similar clinical trials in such high risk patients, EORTC — [] and RTOG — In the GORTEC trial, chemotherapy with docetaxel provided improved survival and locoregional control in locally advanced OPC, but was associated with increased mucositis and need for feeding by gastrostomy.
In the absence of high quality evidence comparing a primary surgical approach to other modalities, decisions are based on consideration of factors such as adequate surgical exposure and anatomically favourable features for adequate resection, post treatment function and quality of life. Such patient selection may enable them to avoid the morbidity of additional adjuvant treatment. In the absence of favourable surgical features the primary treatment of choice remains radiation with or without chemotherapy.

The adequacy of surgical resection is a major factor in determining the role of postoperative adjuvant therapy. In the presence of a positive margin on pathological examination, most radiation oncologists recommend radiation to the primary site, and concurrent chemotherapy. A negative margin is more likely to be treated with lower doses and a smaller treatment volume. Also the removal of a bulky tumour may allow reduced dosage to adjacent uninvolved pharyngeal structures and hence less effect on normal swallowing. The Gel Papillor outcomes local control, regional control, and survival for transoral resection followed by adjuvant therapy are comparable to primary chemoradiation, [] [97] [] so that treatment decisions depend more on treatment-related morbidity, functional outcome, and quality of life.

Patient factors also need to be taken into account, including general baseline functionality, smoking history, anesthesia risk, oropharyngeal function, swallowing and airway protection and potential for rehabilitation. Patient preference is equally important. Many clinical trials are under way focussing on deintensification, often with risk stratification , e. Anatomical considerations may also dictate preference for surgical or non-surgical approaches.
For instance trismus , a bulky tongue, limited extension of the neck, prominent teeth, torus mandibularis a bony growth on the mandible or limited width of the mandible would all be relative contraindications to surgery. Early stage disease [q] is associated with a relatively favourable outcome, for which single modality therapy is recommended, the choice depending on tumour location and accessibility.

For instance unilateral tonsil or tongue base tumours will generally be treated with transoral resection and selective ipsilateral neck dissection.
On the other hand, a large midline tongue lesion would require bilateral neck dissection, but in the absence of what are considered adverse pathology positive margins, extracapsular extension will likely be treated by surgery alone or radiation including ipsilateral or bilateral neck radiation fields, with surgery for those instances where the likelihood of adjuvant therapy is low. This group is mostly treated with multimodality therapy, with the exception of one of the more favourable subgroups with small primary tumours and lymph node involvement confined to a single node no larger than 3 cm in size, which as noted are considered early stage disease.

The three main options for locally advanced but operable disease are resection, neck dissection and adjuvant therapy; chemoradiation with possible salvage surgery ; induction chemotherapy followed by radiation or chemoradiation. However the last option has not been supported in clinical trials that tested it. But this must be balanced against the morbidity and functional loss from extensive resection, particularly where the tongue base is involved. To avoid such morbidity, primary chemoradiation is preferred. The management of disease within the cervical lymph nodes has to be taken into account in treating locally advanced disease.
Guidelines for all OPC dictate that ectracapsular extension be given postoperative chemoradiation.

Where gross neck disease is evident initially primary chemoradiation is usually given. Current guidelines are based on data for OPC as a whole, so that patients are generally being treated regardless of HPV status, yet many clinicians and researchers are considering deintensification.
Patients who have received CRT as primary treatment for OPC place a high value on survival, and although agreeing that deintensification is desirable, were reluctant to trade off much survival advantage for lower toxicity, though would be more likely to forgo chemotherapy than accept reduced radiation. In such situations, resection of the lingual and palatine tonsils together with neck dissection may be diagnostic and constitute sufficient intervention, since recurrence rates are low.

The presence of HPV within the tumour has been realised to be an important factor for predicting survival since the s.
Tumor HPV status is strongly associated with positive therapeutic response and survival compared with HPV-negative Gel Papillor, independent of the treatment modality chosen and even after adjustment for stage. In RTOG clinical trial , [s] in which all patients with advanced disease received radiation and chemotherapy, a retrospective analysis recursive-partitioning analysis , or RPA at three years identified three risk groups for survival low, intermediate, and high based on HPV status, smoking, T stage and N stage see Ang et al. Although the rate of failure in the opposite neck following treatment of only one side, is 2.
For patients such as those treated on RTOG with primary chemoradiation, detailed nomograms have been derived from that dataset combined with RTOG , enabling prediction of outcome based on a large number of variables.

The risk of regional Gel Papillor recurrence after neck dissection is often estimated [] from a large series based on all upper aerodigestive squamous cell Gel Papillors. In this series, the overall risks at three years by pathological stage AJCC 7 were: []. In , squamous cell Gel Papillor of the head and neck region was the fifth most common Gel Papillor other than skin Gel Papillor, globally, with an annual incidence of , cases and about 60, cases annually in the United States and Europe.
The highest incidence age group was 60—69, and was higher in Caucasians than in other races. This in turn may overestimate the severity of the disease status. There has been a global trend in increasing OPC incidence, particularly in North America and northern Europe, but even in Taiwan, which has a very high rate for all Gel Papillors of the head and neck region, OPC rates increased more rapidly between and than any other Gel Papillor site.
