Of all the urinary tract neoplasmas, the vesical tumor is a case with the highest frequency. The medical treatment for vesical tumor holds various problems Its predilection age lies in age between 50 and 70 years old. Its genetic pathology is yet in an unexploited sphere. Chronic stimulation is considered to be the serious factor for its outbreak. Exposure to the aniline coloring matter is assumed to be an inciting cause. 95% of tumors is epithelial and 90% of them is papilloma or papillary cancer resulting from the maligned papilloma.
Medical treatment contains “electro-cautery trans-urethra (TUE of TUR)”, “resection of vesical tumor” “partial cystectomy” and “total cystectomy”, but each of these therapy has problems respectively.
Now, we report on the statistical observation we conducted recently on the vesical tumor in-patients in our hospital extending 9 years between 1958 and 1966. Such in-patients inn this period totaled 60. Among them 49 patients were male and 11 patients were female, the ratio between male and female was five to one. We traced back their development after treatment on the basis of their respective term between the onset of symptom and hospitalization and their histological state of tumor.
We investigated into each treatment after hospitalization, dividing treatments into resection of vesical tumor, partial cystectomy, electro-cautery trans-urethra (TUE or TUR) and non operation, and classifying them into categories of performance and non performance of ⁶⁰CO treatment.
Death case numbered 35 out of 60 in-patient. 31 out of these 35 death cases died within. 3 years after hospitalization. In-patients passing away after survival of longer than 5 years and those alive longer than 5 years numbered 6.
Number of in-patients classified according to their respective treatment after hospotalization is as follows.
However, there were so many inpatients who could not undergo operation, although they were admitted hospitalization, because they were under-malignant conditions. Such categories of cases numbered 24. 10 out of these 24 cases received allopathy only. For this reason, there were 22 in-patients whose histological state was not made clear. Investigation into death case shows that more malignant the histological state is, the prognosis is so much worse.
The prognosis observed on the basis of their respective treatment shows that 6 in patients survived longer than 3 years after resection of vesical tumor, 3 in-patients after TUR survived longer than 3 years respectively. 12 out of 33 cases of total operation survived longer than 3 years, while only 3 out of 27 cases of non-operation survived longer than 3 years. Judging from such state of affairs, the significance of operation and treatmet with. ⁶⁰CO is recognizable.
