We present two cases of squamous cell carcinoma of the laryngopharynx in children less than 15 years of age. Both patients presented with a prolonged history of symptoms and extensive disease at diagnosis.[ncbi.nlm.nih.gov]
A 73-year-old female presented with a primary posterior pharyngeal wall squamous carcinoma and bilateral enlarged neck nodes.[ncbi.nlm.nih.gov]
Subjects with tongue and/or mouth carcinoma presented the worst prognosis, whereas lip carcinoma had the best prognosis. Subjects with verrucous carcinoma had better survival than squamous cell carcinoma.[ncbi.nlm.nih.gov]
We present a case of carcinoma erysipelatoides due to poorly differentiated naso-pharyngeal carcinoma.[ncbi.nlm.nih.gov]
At presentation 26% of the patients had metastatic lymph nodes. A total of 298 primary or secondary nodal recurrences were seen, 159 were treated, and 53 (53/298 approximately 18%) were controlled.[ncbi.nlm.nih.gov]
There was a significant increase in CDDP uptake after hyperthermia at 44 degrees C. These results indicate that high hyperthermia effectively enhances subsequent CDDP cytotoxicity in human pharyngeal carcinoma KB cells.[ncbi.nlm.nih.gov]

Symptoms and Signs Oropharyngeal cancer symptoms vary slightly depending on the subsite but typically patients present with sore throat, dysphagia, odynophagia, dysarthria, and otalgia.[merckmanuals.com]
A neckmass, often cystic, is a common presenting symptom of patients with oropharyngeal cancer. Because the symptoms of oropharyngeal cancer mimic those of common URIs, it often takes many months before patients are referred to a specialist.[merckmanuals.com]
mass Refractory otitis media, epixtaxis, referred ear pain, cranial neuropathy Most common cranial nerves affected are VI and V2 by tumor extension through foramen lacerum into cavernous sinus Syndromes: Jacod's: compression of CN II-VI by extension[en.wikibooks.org]
Complications Orchitis - males may experience pain or lumps in their testicles and swelling in the scrotum. However this rarely causes infertility problems Meningoencephalitis (infection of the central nervous system).[healthhub.sg]
Multivariate survival analysis showed that only two variables were significantly correlated with prognosis: AgNOR counts (P less than 0.001) and the extent of lymphocyticinfiltration (P less than 0.027).[ncbi.nlm.nih.gov]
Both types may have a variety of infiltration with lymphocytes; in some cases there may be lymphocytesinfiltrating between individual cells. This is termed lymphoepithelial carcinoma.[ozradonc.wikidot.com]

Abstract The purpose of this study was to compare Tc(99m) MIBI SPECT imaging with computed tomography (CT) for assessment of post-radiotherapy treatment response in pharyngeal carcinoma.[ncbi.nlm.nih.gov]
The objective of this study was to evaluate retrospectively treatment results in pharyngeal cancers presenting with N2-N3 neck disease, using neck dissection followed by radical locoregional radiotherapy (RT) and to compare these results with those obtained[ncbi.nlm.nih.gov]
Treatment was completed by all, with toxic reactions including myelosuppression, mucositis, and dysphagia. Half of the patients required gastrostomy.[ncbi.nlm.nih.gov]
In contrast, treatment with oxothiazolidine-4-carboxylate (OTZ, a precursor of cysteine), which is known to increase cellular GSH level, decreased the susceptibility of KB cells to LAK killing.[ncbi.nlm.nih.gov]
Males had significantly poor prognosis than females. Subjects with tongue and/or mouth carcinoma presented the worst prognosis, whereas lip carcinoma had the best prognosis.[ncbi.nlm.nih.gov]
Multivariate survival analysis showed that only two variables were significantly correlated with prognosis: AgNOR counts (P less than 0.001) and the extent of lymphocytic infiltration (P less than 0.027).[ncbi.nlm.nih.gov]
CONCLUSIONS: For patients with pharyngeal carcinoma, the HRQL at diagnosis seems to be an important factor for the prognosis of both HRQL over time and survival.[ncbi.nlm.nih.gov]
Early pharynx cancer detected incidentally is associated with a relatively good cancer prognosis. Involvement of lymph nodes in the region is associated with a poorer prognosis of the cancer.[myvmc.com]
Etiology Risk factors Tobacco consumption Alcohol use Further risk factors: nitrosamine ; consumption from salted/preserved foods, chronic iron deficiency, long-term consumption of carcinogenic food (e.g., aflatoxin ), exposure to radiation, immunosuppression[amboss.com]
Recently, HPV infection showed an etiologic role in the development of non-endemic EBV-negative nasopharyngeal cancers. HPV-positive and EBV/HPV-negative tumors exhibited worse outcomes than EBV-positive tumors 7.[radiopaedia.org]
HPV type 16 causes 60% of oropharyngeal cancers, and patients have become younger (median age 57 yr, and bimodal peaks at 30 yr and 55 yr) as HPV infection has emerged as an etiology.[merckmanuals.com]
The etiology of this unique cancer includes three co-factors that include host genetics, Epstein-Barr Virus (EBV) infection, and environmental factors.[grc.org]

Prevention No sure way exists to prevent nasopharyngeal carcinoma. However, one can take steps to reduce the risk of the disease by reducing the intake of salt-cured foods and preserved meats or avoid these foods altogether. (1)Cancer Registry.[healthhub.sg]
Can Nasopharyngeal Cancer Be Prevented? Many cases of nasopharygeal cancer are not preventable, but taking these steps may help lower your risk of nasopharyngeal cancer: Avoid salt-cured fish and meats. Do not smoke. Do not drink a lot of alcohol.[webmd.com]
This study also pointed to a need for providing dentists with new educational updates on OPC prevention and detection [ 45 ].[link.springer.com]
The golden rule that prevention is better than cure still holds true. However, there is a conundrum as screening tests should be proven to reduce morbidity and mortality, besides being socially and ethically acceptable.[star2.com]
