Oropharyngeal cancer is a significant health concern, characterised by the development of malignant cells in the tissues of the oropharynx – the part of the throat located at the back of the mouth, including the base of the tongue, tonsils, soft palate, and walls of the pharynx. This form of cancer is relatively uncommon compared to other types, but its prevalence has been increasing in recent years, particularly among younger individuals, often attributed to human papillomavirus (HPV) infection. Understanding its symptoms, causes, and stages is crucial for early detection and effective treatment.

In conclusion, oropharyngeal cancer presents a complex set of challenges, from its often subtle symptoms to its multifaceted causes and treatment options. Early detection through awareness of symptoms and risk factors, along with advancements in diagnostic techniques and treatment modalities, offers hope for improved outcomes for individuals diagnosed with this form of cancer. 

Oropharyngeal Cancer Symptoms

Oropharyngeal Cancer Symptoms

Oropharyngeal cancer develops in the oropharynx, the middle part of the throat located behind the mouth. This type of cancer can manifest various symptoms, though it’s important to note that other conditions can also cause these symptoms. It’s always best to consult a healthcare professional for a proper diagnosis if you’re experiencing any concerning symptoms. Here are some common symptoms associated with oropharyngeal cancer:

1. Sore throat: Persistent or chronic sore throat that doesn’t improve with time or treatment could be a symptom.

2. Difficulty swallowing (dysphagia): Difficulty in swallowing food or even saliva can occur. This may progress from discomfort to significant pain.

3. Ear pain: Pain in one or both ears that isn’t associated with any other ear problems could be a symptom, as the nerves in the throat can sometimes cause referred ear pain.

4. Voice changes: Changes in the voice, such as hoarseness or a persistent change in tone, may indicate oropharyngeal cancer.

5. Lump or mass: A visible or palpable lump or mass in the neck, throat, or mouth may be present. This lump might be painless or cause discomfort.

6. Unexplained weight loss: Significant and unexplained weight loss can occur due to difficulty eating due to pain or difficulty swallowing.

7. Persistent cough: A persistent cough not due to a cold or allergies could be a sign, especially if it is accompanied by other symptoms like blood in the saliva or difficulty swallowing.

8. Changes in mouth appearance: White or red patches in the mouth or throat, lesions that don’t heal, or ulcers may develop.

9. Bad breath: Chronic bad breath (halitosis) that doesn’t improve with oral hygiene practices may also be a symptom.

10. Swollen lymph nodes: Enlarged lymph nodes in the neck could be a sign that the cancer has spread.

These symptoms can differ in severity & may not always be present. Additionally, some people with oropharyngeal cancer may not experience any symptoms until the cancer is in advanced stages. Therefore, seeking medical attention is crucial if you notice any concerning signs or symptoms, especially if they persist for more than a few weeks. 

Oropharyngeal Cancer Causes

Oropharyngeal cancer, like many cancers, can develop due to a combination of genetic, environmental, and lifestyle factors. Here are some common causes and risk factors associated with oropharyngeal cancer:

1. Tobacco Use: Smoking cigarettes, cigars, pipes, or using smokeless tobacco products significantly increases the risk of developing oropharyngeal cancer. Tobacco contains carcinogenic substances that can damage cells in the mouth and throat, leading to cancerous growth.

2. Alcohol Consumption: Heavy alcohol consumption is another significant risk factor for oropharyngeal cancer. Alcohol can irritate the lining of the mouth and throat, increasing the likelihood of cancerous changes in cells.

3. Human Papillomavirus (HPV) Infection: In recent years, HPV infection, particularly with certain high-risk strains such as HPV-16, has been identified as a significant cause of oropharyngeal cancer. HPV is a sexually transmitted virus that can infect the mouth and throat, leading to the development of cancer over time.

4. Poor Diet: A diet low in fruits and vegetables and high in processed foods may increase the risk of developing oropharyngeal cancer. A diet rich in fruits and vegetables provides essential nutrients and antioxidants that help protect against cancer.

5. Poor Oral Hygiene: Chronic irritation of the mouth and throat due to poor oral hygiene, ill-fitting dentures, or chronic irritation from sharp teeth or dental appliances can increase the risk of oropharyngeal cancer.

6. Exposure to Environmental Carcinogens: Exposure to certain environmental carcinogens such as asbestos, wood dust, nickel, and formaldehyde may increase the risk of developing oropharyngeal cancer, although the link is not as well-established as with tobacco and alcohol.

7. Age and Gender: Oropharyngeal cancer is more common in older adults, with the risk increasing with age. Men are also at higher risk compared to women.

8. Family History and Genetic Factors: While rare, a family history of certain cancers, including head and neck cancers, may increase the risk of oropharyngeal cancer. Additionally, certain genetic factors may predispose individuals to develop this type of cancer.

9. Immune System Suppression: Individuals with weakened immune systems, such as those with HIV/AIDS or those taking immunosuppressive medications, may have an increased risk of developing oropharyngeal cancer.

It’s important to note that while these factors may increase the risk of oropharyngeal cancer, not everyone exposed to these risk factors will develop the disease. Likewise, some individuals may develop oropharyngeal cancer without any known risk factors. Regular screenings and early detection are crucial for improving outcomes in individuals at risk for oropharyngeal cancer.

Oropharyngeal Cancer Staging

The most widely accepted system for staging oropharyngeal cancer is the TNM system, which considers the size and extent of the tumour (T), the involvement of nearby lymph nodes (N), and the presence of distant metastasis (M).

Here’s a detailed look at the different stages of oropharyngeal cancer according to the TNM system:

Stage 0 (Carcinoma in Situ):

– Tis: The cancer is non-invasive and confined to the epithelium, the layer of cells lining the oropharynx.

Stage I:

– T1: The tumour is 2 cm or smaller in its greatest dimension and has not spread to lymph nodes or distant sites.

– N0: No regional lymph node involvement.

– M0: No distant metastasis.

Stage II:

– T2: The tumour is larger than 2 cm but not larger than 4 cm in its greatest dimension without spreading to lymph nodes or distant sites.

– N0: No regional lymph node involvement.

– M0: No distant metastasis.

Stage III:

– T3: The tumour is larger than 4 cm, or there is a minimal extension to nearby tissues such as the epiglottis.

– N0: No regional lymph node involvement.

– M0: No distant metastasis.

– Alternatively, any T1 to T3 with N1 (small, single lymph node involvement on the same side as the primary tumour) and M0.

Stage IVA:

T4a: Moderately advanced local disease. The tumour may have invaded deeper areas or tissues, such as the larynx or the tongue muscles.

– N0 to N1: No or minimal regional lymph node involvement.

– M0: No distant metastasis.

– Alternatively, any T1 to T4a with N2 (multiple lymph nodes involved on one or both sides of the neck) and M0.

Stage IVB:

T4b: This is a very advanced local disease. The tumour has invaded further into the skull base and pterygoid plates or encased the carotid artery.

– Any N: Any level of regional lymph node involvement.

– M0: No distant metastasis.

Stage IVC:

– Any T: Any size or extent of the primary tumour.

– Any N: Any level of regional lymph node involvement.

– M1: Distant metastasis present.

It’s important to note that oropharyngeal cancers associated with HPV (Human Papillomavirus), known as p16-positive cancers, are staged differently due to their distinct behaviour and better prognosis than p16-negative cancers. 

What Is Oropharyngeal Cancer?

Oropharyngeal cancer is a type of cancer that starts in the back of your throat, in an area called the oropharynx. This is the part of your throat behind your mouth, where your tongue and tonsils are. When cells in this area start growing out of control and form a lump or tumour, it can be oropharyngeal cancer. It can make swallowing difficult, cause a sore throat that doesn’t go away, or even change your voice. Smoking, heavy alcohol use, and certain strains of the human papillomavirus (HPV) can increase the risk of developing this type of cancer. 

Oropharyngeal Cancer Treatment

The treatment plan for an individual can vary based on the stage of the cancer, the patient’s overall health, and other factors. Here is an overview of the treatments and their approximate costs in India:

– Surgery: Surgery is often the primary treatment for oropharyngeal cancer, especially in the early stages. It involves the removal of the cancerous tissue and possibly some of the surrounding areas. The surgery cost can range from INR 1,00,000 to INR 3,00,000, depending on the complexity of the procedure and the hospital.

– Radiation Therapy: This treatment uses high-energy beams to kill cancer cells. It can be used alone or in mixture with other treatments. The cost of radiation therapy typically ranges from INR 2,00,000 to INR 5,00,000.

Chemotherapy: Chemotherapy uses drugs to kill cancer cells and may be given before or after surgery or along with radiation therapy. The cost of chemotherapy can vary widely, but it generally starts from INR 1,00,000 per cycle.

– Targeted Therapy: Drugs target specific genes or proteins contributing to cancer growth. The costs for targeted therapy can be pretty high, often exceeding INR 4,00,000 for a course of treatment.

– Immunotherapy: Immunotherapy helps the immune system recognise and fight cancer cells. It’s a newer type of treatment and can be expensive, with costs potentially running into several lakhs per dose.

– Palliative Care: For advanced oropharyngeal cancer, palliative care focuses on relieving symptoms and improving quality of life. The cost will depend on the types of palliative treatments used and the frequency of care needed.

It’s important to note that these costs are approximate and can vary based on several factors, including the specific hospital, the city, and whether the patient opts for treatment at a private or government facility. Additionally, there may be other associated costs, such as medications, follow-up care, and potential complications, that can affect the overall expense of treatment. Patients should consult with their healthcare providers to get a more accurate estimate of the costs based on their specific circumstances.

Are There Ways To Reduce The Risk Of Developing Oropharyngeal Cancer?

There are some things you can do to lower your risk of developing it:

1. Quit Smoking: Smoking tobacco increases the risk of oropharyngeal cancer. So, quitting smoking is one of the best ways to reduce your risk.

2. Limit Alcohol: Drinking alcohol excessively can also raise your risk. Cutting down on alcohol consumption or avoiding it altogether can help lower your risk.

3. Practice Safe Sex: Some types of human papillomavirus (HPV) infections can increase the risk of oropharyngeal cancer. Practising safe sex can reduce the risk of getting HPV.

4. Get Vaccinated: Getting vaccinated against HPV can lower the risk of developing oropharyngeal cancer, especially if you get vaccinated before becoming sexually active.

5. Eat a Healthy Diet: Eating plenty of fruits and vegetables and avoiding processed foods can help keep your body healthy and reduce your risk of cancer.

6. Protect Your Lips: Prolonged exposure to sunlight can increase the risk of lip cancer, which can sometimes spread to the oropharynx. So, using lip balm with sunscreen and wearing a hat can help protect your lips from the sun.

Making these healthy choices can lower your risk of developing oropharyngeal cancer.

Conclusion

Oropharyngeal cancer is a severe condition that affects the throat and mouth area. It can cause symptoms like difficulty swallowing, a persistent sore throat, or voice changes. Smoking, heavy alcohol use, and certain strains of HPV are common causes. Treatment options vary depending on the stage of cancer but may include surgery, radiation therapy, or chemotherapy. If you notice any symptoms, you must see a doctor promptly for evaluation and appropriate care.

Oropharyngeal cancer treatment often entails a combination of surgery, radiation therapy, and chemotherapy, which can be prohibitively expensive. Even with health insurance, out-of-pocket expenses can quickly add up, leaving individuals and families with financial strain. Crowdfunding provides a platform for individuals to reach out to their network, friends, family, and even strangers willing to contribute financially to their cause.
