Two Items Key To Decrease Symptoms And Prolong Survival For Leptomeningeal Carcinomatosis Patients

is one of the most common primary cancers that cause leptomeningeal carcinomatosis (), when cancer spreads to the membranes surrounding the spinal cord and brain. Cases of have increased because of the improved survival of with the help of new advances in treatment. This is the type of cancer diagnosis facing Valerie Harper, who played Rhonda on “The Mary Tyler Moore Show.”

Now research published in the International Association for the Study of Lung Cancer’s Journal of Thoracic Oncology (JTO) shows the effectiveness of intraventricular chemotherapy (chemotherapy injected directly into the ventricles of the brain) in terms of symptom response rate and overall survival in patients with LMC from non-small cell lung cancer (NSCLC).

Researchers from the National Cancer Center in Goyang, Korea did a retrospective analysis on 105 patients with NSCLC who had undergone intraventricular chemotherapy. They conclude that intraventricular chemotherapy for patients with LMC from NSCLC could palliate associated symptoms and prolong patients’ survival.

“Among the 54 patients with increased at the entry of the treatment,” the study says, “20 patients achieved normal (< 15 cm H2O) after the intraventricular chemotherapy, excluding three patients who underwent a ventriculo-peritoneal shunt. However, 15 of 51 patients with normal at the start of treatment showed increased during the course of the therapy and remained uncontrolled. Thus, the total increased control rate of intraventricular therapy was 20 of 69 (29 percent)."

As a result, the researchers conclude that, “Careful selection of patients for intraventricular chemotherapy is recommended, with aggressive ICP control, and concurrent systemic chemotherapy.”
