FIGURE 1 Postoperative smoking cessation of the bladder cancer
patients according to times (months)
The rate of cessation of smoking at female patients was 40% whereas it
was 30.4% at male patients (p=0.06). The mean age of the patients who
stopped and did not stop smoking after the diagnosis were 60.5±8.7 and
60.4±10.4 years, respectively (p=0.966). The pre-diagnosis smoking
frequency of patients who quit smoking was 22.1±11.4 cigarette/day,
whereas it was 21.6±10.0 cigarette/day at patients who did not stop
smoking (p=0.811). It was an elating finding that the frequency of still
smokers decreased to 11.2±8.4 cigarette/day after the surgery
(p<0.001). This data documented even they did not totally quit
cigarettes, smoking frequency significantly decreased after the surgery.
When we asked the reason of cessation of smoking, 32(94.1%) patients
stated that the reason was the diagnosis of BC. Other 2(5.9%) patients
reported that lower respiratory system symptoms were the reason.
There were 28 patients with MIBC at the time of diagnosis. Of these
patients, 21(75.0%) had local disease and underwent radical cystectomy.
Among the patients who had MIBC, 11(39.3%) were smokers at the time of
diagnosis. Surprisingly, the rate of cessation of smoking at these
patients was 27.3% (3 of 11 patients).
The rate of recurrence and progression of NMIBC were 27.0% and 6.8%,
respectively. The rates of recurrence and progression according to
demographic and pathologic findings for NMIBC patients are shown at
Table 2. The smoking status was not related with the recurrence and
progression (p>0.05). The Cox regression model did not show
any relationship between the smoking status and recurrence / progression
(Table 3).
