- Objective:
Testis cancer is the most common cancer in young men, and its incidence
continues to rise. Even if prognosis is considered as good, a group
with bad prognosis still remains. Diagnostic delay (DD), defined as
the time elapsing from the onset of tumour symptoms to the day of diagnosis,
is a way to evaluate the rapidity of diagnosis. We assessed the relationship
between DD, disease stage, and survival rate.
-
Methods:
A series of 542 patients diagnosed with a germ cell tumour between 1983
and 2002 at health facilities in the Midi-Pyrenees region, southwest
France, were asked about DD. We analysed DD together with data regarding
the disease (histologic type, stage), its treatments, and prognosis
(impact on survival).
-
Results:
Mean DD was longer in seminoma (4.9 +/- 6.1 mo) than in non-seminomatous
germ cell tumour (NSGCT; 2.8 +/- 4.0 mo). DD was correlated with disease
stage for the whole population (p = 0.014) and for NSGCT (p = 0.0009),
but not for seminoma. DD had a significant impact on the 5-yr survival
rate in the overall population (p = 0.001) and in the NSGCT group (p
= 0.001), but not in the seminoma group. Global trends in mean DD did
not change over the 20-yr study period, but we observed a slight decrease
during the last decade.
-
Conclusions: DD
is highly correlated with stage and survival in NSGCT. Urologists should
promote programmes to enhance awareness and knowledge of testis cancer,
so the diagnosis can be made more rapidly.
- Editorial
Comment
The authors report on the impact of diagnostic delay on ultimate outcome
on survival. They report on a large cohort of 542 patients over a time
of 20 years. This paper shows quite impressively that testicular tumors
are often neglected by the patients for longer periods. Differences
between seminomas and non-seminomatous germ cell tumors (NSGCT) certainly
relate to the different growth rates between these tumors and how fast
the patient begins to feel uncomfortable with this unclear process in
his scrotum. In fact, diagnostic delay in NSGCT resulted in a significantly
impaired survival. The authors state correctly that consequently, testis
cancer awareness programs should be promoted and young men should be
educated in scrotal self-examination.
One final question however was not addressed in this paper, that is
the role of the physician. Was there any significant delay between first
visit to a physician and diagnosis? Any differences between general
practitioner and urologist?
I recommend thorough reading of this article.
