District Hospital Santarem, Portugal Cryosurgery has enormous capabilities to treat bulky and advanced cancers but this has generally not been recognized. To be able to treat large tumors I devised simple, but very efficient, physical procedures to limit the target area to be frozen and to stop the running drops of liquid nitrogen spray over frozen surfaces unto the healthy skin. The procedures are different and related with the location and stage of the malignancy. For tumors of the head and extremities, bandages are preferred because they are efficient and can be easily applied.
Bandages are unsuitable for the trunk, due to the obvious impossibility of firm application.
Here, paraffin gauze dressings folded 20 times, stitched around the target are indicated. With these principles, I developed several cryosurgical protocols to treat different types of advanced external cancers on various locations, with which I have cured a significant number of patients considered unsuitable for any conventional treatment, and gave palliative relief to many patients. I treated 6 inoperable and radio-resistant, invading basal cell carcinomas of the orbit. Bandages were applied around the orbital region, thermocouples were introduced into the orbit, which was frozen twice, to -50 C with continuos spray. The tumors were adherent to the underlying planes and amputation had been proposed to all of them.
