Details and patient eligibility

About

Guanabana, known also as Graviola or Annona muricata is a tropical fruit which has been commonly used as complimentary/alternative medicine in Latin American countries. The main compounds in Graviola are the annonaceous acetogenins. These acetogenins have been shown to be selective and toxic against various types of cancer cells in-vitro and in-vivo experimental animal models. In spite of this evidence of anti tumor activity of Graviola, no prospective clinical studies have been carried out to determine if it also has clinical activity.The Investigator have observed two patients at Auxilio Mutuo Cancer Center who experienced significant tumor shrinkage while taking a tea made of Graviola leaves. Neither of these patients were taking any other treatment for their cancer. The investigator propose to conduct a study using guanabana leaves extract in patients with Gastroesophageal junction(GEJ) adenocarcinoma, as well as in Gastric adenocarcinoma, Hepatocellular carcinoma, Pancreatic adenocarcinoma, Low Grade Lymphomas and Colorectal adenocarcinoma.

Full description

Patients with relapsed/refractory gastric adenocarcinoma, adenocarcinoma of gastroesophageal junction, hepatocellular carcinoma, colorectal adenocarcinoma will be eligible. Colorectal adenocarcinomas will be eligible after failing second line therapy while the remainder will be eligible after first line therapy depending on the judgment of the treating oncologist. Any patient who refuse to receive chemotherapy will also be eligible even if they have not received chemotherapy. Patients with low grade lymphomas including chronic lymphocytic leukemias whose favorable blood counts and lack of symptoms make the candidates for "watch and wait" approach as well as any patient with low grade lymphoma who because of age or co-morbidity might not be eligible for chemotherapy or who refuse chemotherapy.

Trial design

Primary purpose: Treatment

Allocation: N/A

Interventional model: Single Group Assignment

Masking: None (Open label)

---

54 participants in 1 patient group

Overall Statistical design

Experimental group

Description:

We will treat 9 patients of each tumor type with a tea made of Graviola Leaves. If no responses are observed then the trial will be closed for that particular histological type. Should a response occur, then the trial will continue to the second stage for that cell type until 24 patients are accrued. If 3 or more responses are observed out of 24 cases, then the result will be considered promising.
