A retrospective observational study on cases of osteosarcomas treated with a multitherapy: The rationale and effectiveness

Published on Tuesday, 25 October 2022

Backgrounds: The prognosis of patients with osteosarcoma in many cases remains poor, and life expectancy with lung metastases is around 12 months. Chemotherapy and radiotherapy can only temporarily control neoplastic progression, followed by developing chemo and radioresistant tumours.

Methods: This is a retrospective observational study on 15 patients diagnosed with osteosarcoma and treated by a multitherapy approach. The multitherapy consisted of somatostatin and analogous (octreotide) all-trans-retinoic acid (ATRA), β-Carotene, axerophthol dissolved in vitamin E, vitamin D, vitamin C, melatonin (MLT), proteoglycans, glycosaminoglycans, hydroxyurea, and sodium butyrate.

Results: This multitherapy increased the survival rate and life quality, without overt toxicity, compared to the standard treatment for osteosarcomas. The agents in this approach have several functions. They exert antiproliferative, antiangiogenic, cytostatic, antioxidant, antimetastatic, and immunomodulating features. Moreover, the inclusion of ATRA, MLT, and sodium butyrate has reinforced antitumor properties on cancer stem cells. Furthermore, the non-cytolytic and non-cytotoxic metronomic hydroxyurea dosage increased the biological therapy outcome by strengthening antitumor capability.

Findings: This multitherapy approach is effective against osteosarcoma.

Interpretation: The multistrategy of this multitherapy therapy are inhibiting the proliferative-invasiveness and neoplastic angiogenesis, silencing the survival system of cancer stem cells, enhancing the immunomodulatory and antioxidant activities, improving vitality and efficiency of normal cells, and depressing the efficiency and vitality of neoplastic ones.

For 11 days was administered to the patient, admitted to the general medical ward at the Maggiore-Pizzardi Hospital in Bologna, very slowly (over approx. 8 hours) and intravenously administered 1000 mg of melatonin for 11 days. During the course of each day, the patient was intravenously administered 4 saline drips of 500 ml, each containing ten 25 mg bottles of freeze-dried melatonin, lasting 2 hours, totaling 1000 mg per day. No other drug of any kind was administered in order to ascertain the effect of the MLT without interference [...].
