Summary

Cryotherapy using liquid nitrogen spray effectively treated conjunctival lymphoid tumors in 12 patients. This method showed comparable results to radiation therapy with potentially fewer complications and lower costs for lymphoid tumors.

Area of Science:

  • Ophthalmology
  • Oncology
  • Dermatology

Background:

  • Conjunctival lymphoid tumors are traditionally managed with radiation therapy.
  • Radiation therapy, while effective, can be associated with ocular and systemic side effects.

Purpose of the Study:

  • To evaluate the efficacy and safety of cryotherapy for conjunctival lymphoid tumors.
  • To compare cryotherapy outcomes with traditional radiation therapy.

Main Methods:

  • A case series involving 12 patients with 42 conjunctival lymphoid tumors treated with liquid nitrogen spray.
  • Follow-up duration ranged from 26 to 139 months (mean, 75 months).

Main Results:

  • Tumor resolution rates were 67% after one treatment, 93% after two, and 98% after three treatments.

  • Systemic lymphoma developed in 17% of patients.
  • Outcomes were comparable to those achieved with radiation therapy.

    • Conclusions:

    • Cryotherapy is a viable treatment option for certain conjunctival lymphomatous tumors.
    • Cryotherapy may offer advantages such as fewer ocular and systemic complications and reduced cost compared to radiation therapy.
