Effects of delayed diagnosis on tumor size, stage and grade in bladder cancer.

OBJECTIVE: This study is planned based on the hypothesis that if bladder cancer is detected early, the disease would be less advanced and the possibility of treatment will increase, at least the recurrence-free survival will be longer. Regarding this hypothesis, it is aimed to investigate the effect of delayed diagnosis primarily on the disease factors. MATERIALS AND METHODS: The study included 169 patients, who underwent TUR-BT with the suspicion of bladder cancer in the urology clinic of Afyonkarahisar Faculty of Medicine between April 2018 and April 2023. Demographic and clinical data of the patients were recorded and compared. RESULTS: It was observed that the delay in diagnosis was significantly longer in patients with tumors larger than 3 cm compared to patients with tumors smaller than 3 cm (p < 0.001). In the correlation analysis between tumor size, duration of diagnosis delay, age, T stage, and tumor grade, a low level of positive correlation was observed between tumor size and duration of diagnosis delay, and it was statistically significant (r = 0.215, p = 0.005). CONCLUSION: In our study, it was shown that the tumor size increases as the duration of diagnosis delay increases and this increase causes an increase of 0.088 mm in the pathological size of the tumor in the 1-day delay period. Considering that tumor size changes the risk group of the disease in bladder tumors, and relatedly the follow-up and treatment process changes, we believe that these data will be valuable in the management of bladder cancer.

The effect of diagnosis delay in testis cancer on tumor size, tumor stage and tumor markers.

INTRODUCTION: In testicular cancer, the positive effect of early diagnosis on survival has been known for many years. In this study, we aimed to determine the diagnostic features of testicular cancer patients, to examine the effect of duration of diagnosis delay (DD) on tumor size, tumor stage, and serum tumor markers, and to reveal the possible benefits of early diagnosis. METHODS: A total of 71 patients who underwent inguinal orchiectomy due to suspicion of testicular cancer and whose pathology was found to be the germ cell tumor were included in the study. The relationship between the duration of diagnosis delay and tumor size, level of tumor markers, TNM stage, presence of LAP, and presence of metastasis were examined. RESULTS: Seminoma was detected in 39 (54.9%) patients and non-seminoma tumor was detected in 32 (45.1%) patients. In the correlation analysis between the markers, a significant and positive correlation was found between DD and radiological tumor size, pathological tumor size, retroperitoneal LAP detection rate, LDH and AFP levels, and N stage (respectively; r=0.345 p=0.003, r=0.324 p=0.006, r=0.244 p=0.041, r=0.286 p=0.015, r=0.244 p=0.040, r=0.238 p=0.046). It was determined that a 1-day increase in DD caused an increase of 0.431mm in the pathological size of the tumor. CONCLUSION: Duration of diagnosis delay is an issue that still keeps its importance for testicular tumors. Delay in diagnosis not only leads to an increase in tumor size but also negatively affects tumor stage and prognostic factors.

Effect of obturator nerve block during transurethral resection of bladder tumors on the disease recurrence, progression and surgery outcomes.

OBJECTIVE: In our study, we aimed to evaluate the effect of the obturator nerve block (ONB) on the operation time, duration of hospital stay, complete resection, presence of muscle tissue in the pathology, second resection, recurrence, and progression, when applied in addition to spinal anesthesia in patients with primary bladder lateral wall tumor and Transurethral Resection of Bladder Tumor (TURBT) was planned. MATERIALS AND METHODS: Seventy patients with bladder lateral wall tumors were included in the study. In addition, ONB was applied to 35 of the patients who underwent spinal anesthesia. The two groups were compared in terms of obturator reflex development, perforation, complete resection, presence of muscle tissue in pathology samples, need for second resection, need for second resection due to inadequate muscle tissue, and 1 year recurrence and progression rates. RESULTS: When the two groups were compared for obturator reflex and bladder perforation, both were found to be lower in the ONB group (p = 0.002, p = 0.198, respectively). The rate of complete resection and the presence of muscle tissue in the pathology samples were higher in the ONB group (p = 0.045, p = 0.034, respectively). The rates of second resection and second resection due to inadequate muscle tissue were found to be higher in the group without ONB (p = 0.015, p = 0.106, respectively). In the 1-year follow-up, the recurrence rate was significantly lower in the ONB group (p < 0.001), while there was no significant difference between the progression rates (p = 0.106). CONCLUSION: In our study, we found out that ONB applied in addition to spinal anesthesia increases the rate of complete and muscle tissue resection by decreasing the obturator reflex, and causes a significant reduction in the need for second resection and tumor recurrence.

A household study to determine attitudes and beliefs related to organ transplantation and donation: a pilot study in Yapracik Village, Ankara, Turkey.

Rural areas display adverse attitudes toward organ donation. Through a population-based cross-sectional study of people 18 years of age or older in the rural area of Ankara, Yapracik Village, Turkey, we identified the attitudes and beliefs of people related to organ transplantation and organ donation. The research universe included 87 people in 75 households. The research instrument was a questionnaire. None of the respondents had been involved in organ donation. The percentage of willingness to donate an organ was 47% which was significantly associated with younger age, including 34.4% who expressed willingness while alive. Twenty-five percent believed that their religion is adverse to transplantation, 28% thought it would create pain in death, 20% were afraid, and 83% believed in life afterwards, 15% said that their custom and usage were adverse to organ donation, 50% stated that they can accept organ donation from other races, and 65% stated that they can request organs from their friends. Eighty percent thought that organ donation is a gift given to a human; 34% of them stated that they can be a donor while they are alive. Fifty-four percent of respondents stated that they wanted to get information about organ donation and transplantation. Therefore basic educational campaigns targeting the increase of knowledge about organ donation are warranted in the rural population. There is a need to increase awareness about organ donation and transplantation. Findings like those in this study will help campaigns conducted for organ donation.
