Summary
Localized nasopharyngeal carcinoma (NPC) recurrence can be treated with salvage therapy. Surgery and repeat radiotherapy offer possibilities for retreatment, with best outcomes for limited recurrence and long disease-free intervals.
Area of Science:
- Oncology
- Radiation Oncology
- Surgical Oncology
Background:
- Nasopharyngeal carcinoma (NPC) recurrence after initial treatment presents a challenge.
- Salvage treatment options are crucial for improving patient outcomes.
- Understanding the efficacy of retreatment modalities is essential.
Purpose of the Study:
- To review the experience of retreatment for nasopharyngeal carcinoma (NPC).
- To evaluate the roles of surgery and repeat radiotherapy in managing recurrent NPC.
- To identify factors influencing outcomes after salvage treatment for NPC.
Main Methods:
- Retrospective audit of the Tumor Registry at Prince of Wales Cancer Centre.
- Inclusion of patients with squamous/nonsquamous cell NPC initially treated with radiotherapy.
- Evaluation of patient, disease, and treatment factors, with local control and survival as endpoints.
Main Results:
- 39 patients eligible over 30 years; 25 received primary and retreatment at the center.
- Local control achieved in 41.0% of patients; 5-year overall survival rate was 33.3%.
- Treatment modality significantly impacted local control (P < 0.001) and cancer-specific survival (P < 0.05).
Conclusions:
- Local recurrence of NPC after definitive treatment is potentially salvageable.
- Reirradiation yields better outcomes in cases of limited recurrence volume.
- A disease-free interval exceeding 18 months is associated with improved results from reirradiation.

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
01:23Chronic Pharyngitis
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

01:30Pneumonia V: Nursing management and Prevention
Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
