RESUMO
BACKGROUND: A female patient aged 49 years with a rectal adenocarcinoma underwent tumor resection and multiple follow-up surgical operations whilst receiving compassionate therapy with polyvalent immunoglobulins derived from bovine colostrum (KMP01), a potential modulator of the pro-tumor inflammatory response. AIMS: Assessment of safety of the treatment, effect on tumor recurrence, and effect on parameters associated with the pro-tumor inflammatory response. MATERIALS AND METHODS: The dose of KMP01 varied from 72 g daily in the perioperative period to 12 - 24 g daily thereafter. The pro-tumor inflammatory response was measured using changes in C-reactive protein (CRP) and the lymphocyte-monocyte ratio (LMR). RESULTS: Surgical intervention caused large increases in CRP (up to 400 mg/L) and decreases in the LMR (below target levels of 2.83). However, such changes rapidly returned to normal, where they remained during prolonged treatment with immunoglobulins. Despite the generally poor prognosis associated with a stenotic tumor, cachexia, and multiple surgery, there was no tumor recurrence during the 3-year follow-up. The condition of the patient is good, albeit with a reduced quality of life due to the stoma. CONCLUSION: Polyvalent immunoglobulins constitute a potential and safe prophylactic agent against the pro-tumor inflammatory response. This is the first time that polyvalent immunoglobulins have been used in a colorectal carcinoma patient. The findings can be a basis for further investigations.
