Cisplatin
Standard dosage :The standard dose for use in nasopharyngeal carcinoma is 80 mg/m2 to 100 mg/m2,(slow intravenous) with good hydration. Repeat every 3 weeks.
Contraindications: Contraindicated in patients with known hypersensitivity to platinum compounds,impaired renal function, impaired hearing, myelosuppression, and women who are
nursing or pregnant. Caution should be exercised when using other ototoxic and nephrotoxic drugs.
Main drug interactions: Ototoxicity increases when given with loop diuretics. Renal toxicity increases withaminoglycosides and decreases the effect of phenytoin.
Main side effects: Myelosuppression, dose dependency, severe acute and delayed nausea, cumulative renal toxicity, potassium and magnesium wasting, irreversible paresthesias,
anaphylaxis, and ototoxicity.
Special points: Cisplatin administration has to be done in a supervised setting and by persons familiar with chemotherapy drugs. Vigorous hydration is essential and attention
to electrolyte imbalance is important. Mannitol diuresis may be necessary. Maintain urine output at greater than 100 mL/hour to 150 mL/hour. Aggressive anti-emetic treatment is recommended.
5-Fluorouracil
Standard dosage: The standard dosage for nasopharyngeal carcinoma is 1000 mg/m2/day, continuous
infusion for 4 to 5 days. This dose is repeated every 3 weeks.
Contraindications: Contraindicated in patients with known hypersensitivity, hepatic and renal
diseases, myelosuppression, and unstable angina.
Main drug interactions: Not compatible with diazepam and droperidol.
Main side effects: Myelosuppression, dose-dependent nausea and vomiting, mucositis, angina, alopecia, hand-foot syndrome, and diarrhea.
Special points: Dose reduction is necessary in patients with liver disease. Avoid use in patients with familial pyrimidenemia, because it can lead to fatal neurotoxicity.

Overview

The mainstay of therapy for nasopharyngeal carcinoma is external beam radiotherapy, supplemented in some cases with chemotherapy.

Medical Therapy

The mainstay of therapy for nasopharyngeal carcinoma is external beam radiotherapy.

  • Standard treatments for patients with nasopharyngeal carcinoma include:[1]
    • External beam radiation therapy alone
    • Concurrent chemoradiation followed by adjuvant chemotherapy
    • Chemotherapy alone for metastatic disease
  • Undifferentiated subtype of nasopharyngeal carcinoma is highly radiosensitive

Treatment according to Stages

Stage Treatment

Stage 1

  • External beam radiation

Stage 2

  • Chemotherapy given with radiation therapy, followed by more chemotherapy
  • Radiation therapy to the tumor and lymph nodes in the neck

Stage 3

  • Chemotherapy given with radiation therapy, which may be followed by more chemotherapy
  • Radiation therapy
  • Radiation therapy followed by surgery to remove cancer -containing lymph nodes in the neck that remain or come back after radiation therapy

Stage 4

  • Chemotherapy given with radiation therapy, followed by more chemotherapy
  • Radiation therapy
  • Radiation therapy followed by surgery to remove cancer -containing lymph nodes in the neck that remain or come back after radiation therapy
  • Chemotherapy for cancer that has metastasized (spread) to other parts of the body

Medical Therapy

  • Pharmacologic medical therapy is recommended among patients with nasopharyngeal carcinoma, [disease subclass 2], and [disease subclass 3].
  • Pharmacologic medical therapies for nasopharyngeal carcinoma include (either) [therapy 1], [therapy 2], and/or [therapy 3].
  • Empiric therapy for [disease name] depends on [disease factor 1] and [disease factor 2].
  • Patients with [disease subclass 1] are treated with [therapy 1], whereas patients with [disease subclass 2] are treated with [therapy 2].

Cisplatin

Standard dosage :The standard dose for use in nasopharyngeal carcinoma is 80 mg/m2 to 100 mg/m2,(slow intravenous) with good hydration. Repeat every 3 weeks.

Contraindications: Contraindicated in patients with known hypersensitivity to platinum compounds,impaired renal function, impaired hearing, myelosuppression, and women who are

nursing or pregnant. Caution should be exercised when using other ototoxic and nephrotoxic drugs.

Main drug interactions: Ototoxicity increases when given with loop diuretics. Renal toxicity increases withaminoglycosides and decreases the effect of phenytoin.

Main side effects: Myelosuppression, dose dependency, severe acute and delayed nausea, cumulative renal toxicity, potassium and magnesium wasting, irreversible paresthesias,

anaphylaxis, and ototoxicity.

Special points: Cisplatin administration has to be done in a supervised setting and by persons familiar with chemotherapy drugs. Vigorous hydration is essential and attention

to electrolyte imbalance is important. Mannitol diuresis may be necessary. Maintain urine output at greater than 100 mL/hour to 150 mL/hour. Aggressive anti-emetic treatment is recommended.

5-Fluorouracil

Standard dosage: The standard dosage for nasopharyngeal carcinoma is 1000 mg/m2/day, continuous

infusion for 4 to 5 days. This dose is repeated every 3 weeks.

Contraindications: Contraindicated in patients with known hypersensitivity, hepatic and renal

diseases, myelosuppression, and unstable angina.

Main drug interactions: Not compatible with diazepam and droperidol.

Main side effects: Myelosuppression, dose-dependent nausea and vomiting, mucositis, angina, alopecia, hand-foot syndrome, and diarrhea.

Special points: Dose reduction is necessary in patients with liver disease. Avoid use in patients with familial pyrimidenemia, because it can lead to fatal neurotoxicity.
