Page Background

A technology that allows fast teaching with good

functional and oncological results in a short period of time

should be considered a great improvement, not only for

patients but also for health care systems.

summary:

This contemporary, cross-sectional investigation of 952 testic-

ular cancer (TC) survivors cured after four cycles of etoposide

and cisplatin (EPX4,

n

= 294) or three or four cycles of bleo-

mycin, etoposide, cisplatin (BEPX3,

n

= 364; BEPX4,

n

= 170)

evaluated for the type and prevalence of adverse health out-

comes (AHOs). At median time from chemotherapy of 4.3 yr,

the median number of AHOs in both the EPX4 and BEPX3

groups was two, with 34.3% and 35.1% of survivors, respec-

tively, reporting three or more AHOs. While the most common

AHOs including tinnitus and hearing impairment were similar

between the groups, there were significant differences in the

AHO type and incidence between the EPX4 and BEPX3 groups

for Reynaud's phenomenon (11.6% vs 21.4%;

p

<

0.01), periph-

eral neuropathy (29.2% vs 21.4%;

p

= 0.02), and obesity (25.5%

vs 33%;

p

= 0.04). Increasing age and current smoking were

associated with higher AHO rates, while exercise provided a

protective effect.

comments

:

Owing to excellent cure rates in metastatic TC, minimizing

treatment-related morbidity is paramount. For patients with

a good risk profile, some strategies to lessen adverse effects

have been successful, such as elimination of a fourth BEP

cycle, but others failed, such as attempts to substitute car-

boplatin for cisplatin

[1,2]

. In an effort to avoid bleomycin-

associated toxicity, Culine et al

[3]

directly compared EPX4

and BEPX3. The primary endpoint of favorable response

(94.7% vs 96.8%) and secondary endpoints of event-free

survival (91% vs 86%) and 4-yr overall survival (97% vs

93%) were not significantly different between the groups.

The National Comprehensive Cancer Network endorses EPX4

or BEPX3 for TC patients with a good risk profile

[4]

, although

the equal efficacy of EPX4 and BEPX3 is not uniformly ac-

cepted

[5]

.

There is a paucity of data on the impact of an additional

cycle of EP (in patients receiving EPX4) or of potentially

synergistic adverse effects of bleomycin and cisplatin (in

patients receiving BEPX3) on late adverse consequences in

TC survivors. Fung et al highlight differential toxicity

profiles for these two commonly used regimens. Impor-

tantly, cumulative bleomycin doses were significantly

associated with five or more AHOs, whereas cumulative

cisplatin doses were not. Bleomycin-associated pulmonary

toxicity was not assessed. Furthermore, patients were not

stratified by receipt of post-chemotherapy retroperitoneal

lymph node dissection, which was performed in 48% of

patients and could impact AHOs. As these data mature,

critical information regarding cardiovascular toxicity and

secondary malignancy will also arise, influencing the

debate on optimal treatment for favorable-risk TC.
