[CANCER RESEARCH 37, 2895-2897, August 1977] Survival following Transurethral Resection of Bladder Carcinoma1 Roger W. Barnes,2 Arthur L. Dick, Henry L. Hadley, and Oliver L. Johnston Section of Urology, School of Medicine, Loma Linda University, Loma Linda 92354 (A. W. B., H. L. H., 0. L. J.), and Department of Urology, White Memorial Medical Center, Los Angeles, California 90000 (A. L. D.) Summary Most low- and medium-stage (0, A, B1 and B2) and low grade (I and II) tumors can be cured or controlled by ade quate transurethral resection. This means wide and deep removal of the tumor, frequent follow-up examinations, and resection or electrocoagulation of recurrences. The 5-, 10-, 15-, and 20-year survivals of patients with low-stage and low-grade cancers compare favorably with the survival fol lowing more radical treatment (1 , 3-7). Introduction The survival of patients with bladder cancer is 1 criterion by which the effectiveness of treatment can be judged. This review was carried out to determine the survival of patients treated by transurethral resection. Materials and Methods This report consists of data from the records of 573 pri vate patients treated between 1931 and 1969 who either have been followed for 5 or more years after initial treatment or have died less than 5 years after treatment. Three hundred seventy-seven (66%) of these had transurethral resection of the bladder tumor with the intent of either cure or effective control of the neoplasm. The remaining 96 (34%) are not included in this study because the transure thral resection was done for biopsy only or for palliation only (usually to control hemorrhage), or else open surgery was performed. The reason the totals in all categories do not equal 277 is that information on some patients was missing in some categories. Patient ages ranged from 23 to 92 with a mean age of 64. Fifty-two % of all patients had only 1 transurethral resec tion and no recurrence in a period of 5 years or longer (Table 1). Six % had more than 6 procedures. The largest number of recurrences that any patient had was 32; most of these were small tumors that were electrocoagulated in our office as an outpatient procedure. An estimation of the grade of the tumor was made by the pathologist at the time the tumor was removed. All sections that were available were reexamined at the time the study I Presented at the National Bladder Cancer Conference, November December 1, 1976, Miami Beach, Fla. a Presenter.

The stage of the tumor was estimated from the gross appearance of the tissues at the time of resection, from the physical and laboratory examinations, and from the pathol ogy report. It is difficult to stage accurately bladder tumors that have been removed by transurethral resection . Stage A in this report includes Stages 0 and A (mucosa and submu cosa); Stage B includes Stages B, and B2 (into but not through muscle); Stage C has invasion of penivesical tis sues; and Stage 0 has evidence of metastases. It is probable that many of the cases in this report are understaged, but it is evident that the majority of these patients had compara tively small and low-stage tumors. Survival Patient survival is a significant measure of the efficacy of treatment. The 5-, 10-, 15-, and 20-year survivals of persons in the general population age 64, which is the median age of the patients in this report, are 87, 71 , 53, and 32%, respec tively (2). The stage of the disease at the time of the 1st examination (Table 2) is the most significant factor affecting survival, although the grade and the size of the neoplasm correlate closely with the stage. Most Stage A tumors are small and are low grade; most Stage B are larger and more malignant, and those that have invaded through the bladder wall (Stage C) and have metastasized (Stage D) are mostly large and more malignant. As shown in Table 2, the survival (crude survival; not corrected for expected survival) of patients with Stage A tumors was significantly less than in the gen eral population (p < 0.001 ). The survival of patients in whom the stage could not be determined from the description of the operative procedure or from the report of the patholo gist is almost identical with that of those that were docu Table 1 Number of endoscopic procedures of total pa of patients% No.tients1194522772134512416451136103More of proceduresNo. to than 6216 AUGUST 1977 Downloaded from cancerres.aacrjournals.org on April 29, 2017. © 1977 American Association for Cancer Research. 2895 R.

There were only 6 Stage C and Stage D tumors that were recorded as attempted cures or controls. Although 2 of 3 Stage C tumors so designated lived more than 10 years, the number is too small to be significant. The survival rate for patients with low-grade tumors (Ta ble 3) was better than that for those with high-grade tumors. Themewas 13% 15-year survival of Grade III and Grade IV tumors. The 5-year survival (85%) of Grade I tumors is not significantly different from that in the general population (87%) (p > 0.05). For the longer periods of observation, the survival is significantly lower than that in the general popu lation. The size of the tumor has survival matesignificance (Table 4). The smaller the tumor the better is the survival rate. The survival rate of patients with tumors less than 1 cm is some what better in all periods of observation than the Stage A tumors. Themeare too few tumors in the group with tumors larger than 6 cm for the survival percentages to be signifi cant. Most of the large tumors were removed by open sur gery and are not included in this study. A combination of stage and grade (Table 5) shows many Table 2 Survival rates in relation patients5 yr+A47/64StageNo. (25)B23/75 (10)Not “Numbers in (71)52/1 166/275 (62)83/225 parentheses, yr+20 (28)5/20 (16)3/30 18 (44)34/102 (37)50/179 (33)15/66 (28)23/1 16 percentage.

Resection more high-grade tumors in Stage B than in Stage A (43 versus 5) and, conversely, many more low-grade tumors (I and II) in Stage A than in Stage B (49 versus 29). The best survival rate, as would be expected, is in the Grade I Stage A group, 81% 5-year survival, which is not significantly differ ent from that in the general population (p > 0.05).

Further study is necessary to determine which ones will progress to a higher stage and grade.
