            Tumor cells behaviour could be influenced by HIF variations

Pituitary tumors are associated with important morbidity due to compression, hormonal
hypersecretion or secondary hypopituitarism. The angiogenic phenotype of the tumors may
play an important role in tumor behavior. Hypoxia inducible factor (HIF), a transcriptional
factor composed of two subunits (and) plays a key role in angiogenesis, activating
proangiogenic factors, such as VEGF. The HIF subunits are critically regulated by oxygen
but also modulated by growth factors.
Aim. To study how HIF expression relates to and influences tumor behaviour in pituitary
tumors.
Methods. The effects of hypoxia and different growth factors on HIF- stability and function
were performed in vitro, in rat pituitary GH/PRL secreting GH3 cells. The protein
expression was evaluated by Western blot and the function and translocation by luciferase
assay. Evaluation of the expression of target genes was done by quantitative RT-PCR. We
also performed immunohistochemistry (IHC) on 11 pituitary adenomas (both secreting and
clinically not secreting type) looking for the hormonal expression and also for HIF1 , HIF2
and CD31 expression.
Results. We were able to show that both HIF alpha congeners were increased in the GH3
cell line by low oxygen tension (O2=1%) and also by growth factors: IGF1 (100 ng/ml) and
dopamine (400 µM). The transcription activation potency of HIF was also increased as
assessed by transient hypoxia-inducible reporter gene assay and RT-PCR of its target genes.
The incubation of GH3 cells with dopamine in hypoxia led also to an increased angiogenesis
as assessed by the capacity of tube formation. In vivo, both HIF alpha congeners were
expressed in the pituitary adenomas. HIF-2 expression didn't correlate with the angiogenic
phenotype assessed by CD31 (IHC) or indirect by levels of serum VEGF (ELISA).
Conclusion. HIF- subunits are modulated in pituitary cells by oxygen and growth factors.
HIF- variations influence the tumoral cells behavior with a potential different impact on
tumorigenesis of the two alpha subunits (HIF-1 and HIF-2) .

Natural history of sporadic goiter: a case of giant

Background. Longstanding goiter can delay the
diagnosis and treatment of thyroid cancer.
Aim. To present a case of giant thyroid carcinoma
developed within a remnant thyroid lobe, long after
hemi-thyroidectomy.
Case report. The patient, a 77 years old female, from
a non-iodine-deficient area, with a history of right
hemi-thyroidectomy for goiter, 36 yrs. before
presentation, was hospitalized for a giant left-sided
cervical mass. This developed slowly after operation
and had grown rapidly within the last 5 months. On
examination, a firm, non-tender left cervical mass
(15/12cm in diameter) with suprajacent skin changes,
emaciation, palor and tachycardia were present.
Laboratory evaluation showed supressed TSH with
normal freeT4, anemia (hemoglobin=8.4 g/dL) and
elevated ESR. CT examination demonstrated a
heterogeneous mass extending to the mediastinum,
with calcifications and necrosis. Tumor diameters
were 17/12/14 cm. Trachea was displaced, with
diameters of 2.26/1.38 cm. FNAB was not diagnostic
for carcinoma. Management. After correction of
anemia, total thyroidectomy was performed.
Thyroxine substitution was begun and the anemia
recovered spontaneously. The hystopathological
diagnosis was follicular poorly differentiated, highly
invasive and angio-invasive carcinoma, stage PT4B
PNX ST4B G3 R1 V1. External beam radiotherapy
was planned, but could not be performed because of a
local ulcerated recurrence of the tumor, six weeks after
thyroidectomy. The patient decided against further
surgery and was lost to follow-up.
Conclusion. Thyroid carcinoma should be suspected
in patients with progressive enlargement of
preexisting goiter. In our patient, recurrence of the
goiter on the remnant lobe after hemi-thyroidectomy
led to a delay in diagnosis.
