Everolimus may not be universally prescribed to prevent tumor recurrence in liver transplant patients with hepatocellular carcinoma. Future randomized trials should be focused on patients with histological features of increased tumor aggressiveness, in whom the potential benefit would be higher.

Fine needle aspiration biopsy (FNAB) performed for diffuse and nodular goiter in the past 5 years, was evaluated in 1399 cases. Surgery was performed on the basis of FNAB cytologic diagnosis that was positive or suggestive of malignancy and/or a suggestive clinical history. Surgery also was performed in cases of cold nodules with negative FNAB results that did not respond to 6 months of suppressive thyroxine therapy. A correlation of cytologic findings with histologic findings was possible in 415 patients who underwent surgery: the evaluation of FNAB results yielded better results when suspicious cytologic findings were considered to be positive (2.4% false-negative, 86.3% sensitivity) rather than negative (6.5% and 65.78, respectively). FNAB has become a useful procedure in the study and diagnosis of thyroid diseases. It is a simple, rapid diagnostic procedure that may be used to expedite the management ofmalignant lesions.Cancer 59:1206-1209, 1987. INE NEEDLE ASPIRATION BIOPSY (FNAB) has beenF introduced in our hospital in the past 5 years as a routine procedure for the study of thyroid disease. In some centers, FNAB is a safe and inexpensive tool in the study of thyroid nodules, although it is not yet widely used, partly because it requires the services of an expert cyto-The majority of reports on the technique refer to nodular goiter, using FNAB to distinguish benign from malignant lesions pre~peratively,*-~ although thyroid nodules only represent about 20% of thyroidopathies.6 We have undertaken a study to evaluate the usefulness of FNAB as a complement to clinical, hormonal, gammagraphic, and ultrasonographic studies in both diffuse and nodular goiters.

Patients were not selected for this study, but their specific consent was required. Age ranged from 9 to 84 years (mean, 43 years); 10.5% of the patients were male and 89.5% were female. FNAB was always made after clinical and biochemical (thyroid hormones and antibodies) studies, 9 9 m T~ imaging, and ultrasonography. According to these tests, 261 cases were diffuse goiters, 281 were multinodular goiters, 83 5 were solitary thyroid nodules, and 22 were miscellaneous. A correlation was established between cytologic findings (FNAB) and postoperative pathologic results in 415 patients. Surgery was performed on subjects with positive or suspicious FNAB cytologic diagnoses and/or suggestive clinical histories, and in patients with cold thyroid nodules and negative FNAB results that did not respond to 6 months of suppressive thyroxine therapy.The procedure was similar to that described by Lowhagen et ~1 .~ Using a Cameco syringe pistol (Cameco AB, Taby, Sweden) with 0.6 to 0.8 mm gauge needles that were 20 mm in length.

We describe a case of Strongyloides stercoralis hyperinfection in a liver allograft recipient 2.5 months after transplantation. The patient lives in Spain, which is not considered an endemic country for strongyloidiasis, and denied prior residence or travel to any known endemic area. The initial symptoms were fever and vomiting, and he subsequently developed a severe respiratory disease. An endoscopic biopsy of ulcerative lesions of the duodenum revealed massive mucosa infiltration by larvae and adult worms, which were also found in respiratory samples. The patient was successfully treated with combined therapy with albendazole and ivermectin. The strongyloides infection was transmitted by the liver allograft. The donor was from Ecuador and, retrospectively, his serum tested positive for S. stercoralis IgG antibodies. Additionally, the pancreas-left kidney allograft recipient from the same donor later developed an intestinal strongyloidiasis without hyperinfection syndrome. To our knowledge, this is the first confirmed case of S. stercoralis infection transmission from the same donor to two solid allograft recipients.
