Immunotherapy with Subcutaneous Injection of Immunomodulatory Agent (OK-432) Elicits Durable Response in Locally Advanced or Relapsed Cervical Cancer.

Immunotherapy (IT) has been studied as a new and alternative treatment option for locally advanced, persistent, recurrent, or relapsed cervical cancer in an effort to extend the life and possibly cure patients with advanced stage disease. Targeted immune checkpoint inhibitors augment anticancer immunity and prolong patient's life span without immune-related adverse events (irAEs). Here, we present a case of a 56-year-old woman, gravida 2 para 0, diagnosed with squamous cell carcinoma of the cervix stage IVB who received IT coupled with subcutaneous injection of immunomodulatory agent (OK-432) during her standard treatment of concurrent chemoradiation therapy (CCRT) and as a maintenance therapy after CCRT due to relapsed cervical cancer.
