the parameters studied were: the incidence of periopera-
tive complications and outcomes after surgical procedures
between the two cohorts. The median preoperative renal
mass size was 11 cm (6.7 - 4.2 cm). Primary tumor
shrinkage was seen in 57%; median shrinkage was 18%
(8% - 25%). The median treatment period was 17 weeks,
and the median time from TKI discontinuation was 2
weeks. Compared with a control group and after adjust-
ing for confounding covariates, presurgical TKI use was
not associated with a significant increase in perioperative
complications (50% vs 40%, P = 0.25) or perioperative
bleeding (36% vs 34%, P = 0.97) but was associated
with increased incidence and grade of intraoperative ad-
hesions (86% vs 58%, P = 0.001; grade 3 vs 1, P =
0.002). They concluded that they found less hemorrhagic
and wound healing issues but a significant increase in
incidence and severity of intraoperative adhesions, which
can present a formidable technical challenge. The pre-
surgical TKI therapy can permit effective surgical cy-
toreduction with a safety and complication profile
equivalent to that of non-TKI-nephrectomy; however
safety data continue to evolve, and preoperative TKI use
requires further prospective investigation [12].
5. Conclusions
Sorafenib is a drug that inhibits specific proteins in neo-
plastic cells, it modulates transduction signal and has
shown to create intratumoral ischemic necrosis. The
NCCN [9] and the EUA [13] guidelines have suggested
that this drug can be used as a first line of treatment and
the neoadjuvant setting should be investigated thor-
oughly.
