There are a great variety of tumors that develop in the upper and lower limbs, which may be both primary and metastatic. Osteosarcoma, Ewing’s sarcomas, condrosarcomas, and others mainly belong to a juvenile pathology while the metastatic types concern more adult pathology.
The attempt to destroy them consists of using sodium bicarbonate solution at five per cent in doses that are proportional to the weight of the patient. This is achieved through the application of catheters in the afferent arteries to each limb.
All the masses downstream of the application point generally regress almost completely, even though in some cases the effects of the therapy become visible only three to four months later when, that is, the tissue re-absorption and reshaping phenomena are almost completed.
The only real problem with this therapy is that the arteries of a young patient are of small cross-section, and that means that for each administration the insertions and the stretching of the nerva vasorum produce a steady, painful symptomatology.
The symptoms, however, are temporary, and apply only during the period of administration. Nevertheless this sometimes forces the suspension of the treatment for one or two days.
In the case of bone metastasis, it is possible to obtain an almost complete remission of the painful symptoms by performing direct percutaneal infiltrations on each lesion. This can be done by leaving a cannula needle in contact with the bone.
