We report 82 patients with renal pelvic and ureteral tumors admitted to Kyoto Prefectural University of Medicine, Kyoto Second Red Cross Hospital and Shakai-Hoken Kyoto Hospital between January, 1981 and December, 1991. Sixty two were males and 24 were females, and they were between 47 and 93 years old (average: 68.2 years). The tumor occurred on the right side in 34 patients, on the left side in 51 patients and on both sides in one patient. There were 43 renal pelvic tumors, 37 ureteral tumors and 6 renal pelvic with ureteral tumors. The most frequent symptom was macrohematuria, which was seen in 54 patients (62.8%). Urinary cytology was performed in 76 patients and a positive result was obtained in 44 patients (57.9%). We performed surgical treatment on 71 patients. The most frequently adopted method was total nephroureterectomy with partial cystectomy which was performed on 51 patients (71.8%). Of the 73 specimens diagnosed histopathologically, 71 specimens were transitional cell carcinoma (TCC), one was a squamous cell carcinoma (SCC) and one was a mixed type of TCC and adenocarcinoma. As to grading, 6 specimens were G1, 28 G2, 38 G3 and one GX. As to staging, 8 specimens were pTa, 17 pT1, 21 pT2, 18 pT3, 8 pT4 and one pTX. The overall survival rate (by Kaplan-Meier's method) at 3 and 5 years was 47.0% and 39.5%, respectively. The patients with high grade tumors and those who had ureter preservation, the survival rate was lower than in the other patients.

Fluorescence in situ hybridization (FISH) using chromosome-specific alpha-satellite DNA probes for chromosomes 7, 8, and 12 was performed on paraffin-embedded tissue sections and touch imprint preparations of 53 cases of human prostate cancer. Subsequent haematoxylin and eosin (H & E) staining of the hybridized tissue sections allowed unambiguous assignment of hybridization signals either to tumour or to non-tumorous parenchyma. Fifty-three cases of human prostate cancer were evaluated for numerical aberrations of chromosome 7. Scoring 200 cells of tumour and non-tumorous parenchyma in each case revealed abnormalities exclusively in tumour parenchyma in 41 cases (77 per cent). Ten of 41 cases (24 per cent) showed trisomy 7, and 15 cases (37 per cent) monosomy 7 or trisomy 7 in combination with monosomy 7, respectively. Sixteen cases (39 per cent) exhibited polysomy 7 in cells of the tumour parenchyma. In the tumour tissue in one case, different polyploid clones (triploid, tetraploid) and polysomy 7 could be identified by double hybridization with chromosome-specific DNA probes for chromosome 7, plus 8 or 12. The indicated numerical aberrations of chromosome 7 were correlated with 78 per cent of advanced pathological stages or poorly differentiated tumours (pT3/4 or G3) of prostate carcinomas. A statistical analysis of the data revealed significant relationships of particular numerical abnormalities of chromosome 7 to different pathological categories (pT, G, pN) of tumour classification. For the T-classification, the frequency of cells carrying polysomy 7 and polysomy 7/+7 increases significantly from pT1 to pT3/4 (P = 0.022).(ABSTRACT TRUNCATED AT 250 WORDS)

Retrospective study conducted on 58 patients with vesical diverticulum seen in our unit between 1975 and 1992, of which a total of 11 (18.9%) patients had vesical tumours. Of these, 6 (10.3%) were intradiverticular and 5 (8.6%) extradiverticular. Sixty-six percent of patients with intradiverticular tumours also had prior or concurrent history of extradiverticular vesical tumours. The most frequent clinical presentation was gross haematuria. The abdomino-pelvic CT is the most sensitive morphological examination although in 33% cases it resulted in overstaging. Curative treatment was only possible in the 4 patients with urothelial tumours, in whom 3 partial cystectomies with pelvian lymphadenectomy (2 pT1 G2 and 1 pT3 G3) and 1 TUR (T1 G2) were performed. The 2 (33%) remaining patients had advanced locoregional epidermoid carcinoma (T4 N+). All patients with urothelial carcinoma are alive with follow-up ranging between 6 months for the one infiltrant case and 136 months for a surface tumour undergoing partial cystectomy. Prognosis for both epidermoid carcinoma was ominous with mean survival time of 9 months. Review of the literature and discussion of epidemiological, clinical, diagnostic, therapeutic and prognostic issues.

In 127 patients with urothelial carcinoma of the bladder the ploidy, deoxyribonucleic acid (DNA) heterogeneity and counts of cell cycle phases in the tumor were analyzed by means of single cell DNA cytophotometry with the intention of finding new prognostic factors in addition to those already known (stage and grade). Patients were followed for 1 to 9 years. The results of the DNA analyses were related to the tumor categories, histopathological grading of the tumor and clinical course. Tumors were histologically classified as grade 1--DNA frequency peaks in the diploid range, grade 2--heterogenous DNA distribution patterns, and grade 3-73% aneuploid and 27% tetraploid DNA values. The proliferation rate of the tumor cells was statistically greater in cases of histological grades 2 and 3 malignancy than in grade 1 malignancy. There was also a positive correlation between tumor stage and DNA ploidy. The cell lines were aneuploid in 38% of the patients with stage pT1, 64% with stage pT2 and almost 85% with stage pT3 tumors. A significant correlation was found between the results of DNA cytophotometry and the clinical course of the disease. Patients with diploid tumor cell lines had no metastases and no local tumor progression for up to 9 years, whereas patients with multiple aneuploid tumor cell lines suffered recurrence and local tumor progression within 6 to 36 months. On the average, the patients died of the tumors 26 months after primary diagnosis. The difference in tumor recurrence and in tumor progression between patients with aneuploid and diploid tumors was highly significant (p < 0.001). The prognosis for patients with grade 1 tumors is good, whereas it is unfavorable in the case of grade 3 tumors. For these 2 groups DNA ploidy affords no additional prognostic information. Grade 2 tumors, on the other hand, are heterogeneous in respect to DNA ploidy, although they exhibit the same degree of histomorphological differentiation. These tumors can be subclassified as aneuploid (biologically aggressive) and diploid or tetraploid (biologically less aggressive). In terms of multivariate Cox regression analysis, DNA ploidy compared with grade and tumor stage was the strongest predictor of survival.

In 86 patients with histologically proven oesophageal carcinoma endoscopic ultrasonography (EUS) and computerised tomography (CT) were performed during TN-staging (UICC 1987). 44 patients were operated on and the histological findings were compared with the results of preoperative staging. The T-stage was correctly determined with EUS and CT in 35 (80%) and 24 (55%) patients, respectively. The accuracy of EUS was 75%, 71%, 91% and 67% in stages T1 to T4. The sensitivity of EUS in the diagnosis of lymph node metastases was 91%, that of CT 42%. The specificity of EUS and CT was 64% and 100%, respectively. The accuracy for pN staging (N0/N1) was 84% with EUS and 57% with CT. The presence of local lymph node metastases was closely correlated to the pT-stage (1 patient [14%] with pT1-, 5 patients [71%] with pT2-, 21 patients [95%] with pT3- and 6 patients [100%] with pT4-stage). In 12 out of 34 patients (28%) tumour induced stenosis prevented a complete oesophageal passage of the EUS probe. This fact, however, did not compromise TN-staging significantly. Our study demonstrates that EUS is an efficient method in the locoregional staging of oesophageal carcinoma. Especially in the early tumour stages T1 and T2 and in the demonstration of local lymph node metastases EUS is superior to CT.

Despite careful clinical staging, as many as 30 percent of patients with pathologically, specimen-confined renal cell carcinoma (RCC) have unpredictable recurrence following surgery. Present pathologic and clinical staging systems cannot accurately predict those patients with high risk of disease recurrence from those who are cured by surgery alone. Advances in immunotherapy including gene therapy for RCC have dictated the need to identify RCC patients for adjuvant therapy protocols who have a high probability of recurrence following nephrectomy. Nuclear morphometric techniques developed at our institution have predicted prognosis for a variety of genitourinary tumors; it was used to predict recurrence among patients undergoing nephrectomy for localized RCC. This report is a retrospective study of 26 patients with RCC of similar age, stage (pT1-pT3), and grade. Fifteen were free of disease at a mean of 75.2 months, and 11 had distant disease recurrence at a mean of 27.1 months. Statistical analysis of a variety of nuclear shape descriptors accurately separated this group of patients based on disease recurrence. No nuclear shape descriptor predicted disease recurrence when nuclei within the region of the tumor with the highest grade were analyzed. However, the range of nuclear ellipticity (p = 0.007) best predicted disease recurrence when nuclei were selected in a random fashion. Multivariate analysis of the four best shape descriptors better predicted disease recurrence (p = 0.002) with a sensitivity of 73 percent and specificity of 100 percent. These results are encouraging and suggest that this technique might be used in identifying patients for adjuvant gene therapy.

To clarify the relative importance of clinicopathological factors affecting survival in patients with renal cell carcinoma, univariate and multivariate analyses by Cox's proportional hazards model were performed for 121 patients undergoing nephrectomy between 1980 and 1991. The 5-year survival rate was 67% for all 121 patients. Univariate analysis revealed that distant metastasis, local invasion, venous involvement, infiltration pattern, grade, lymph node metastasis, sex, and tumor size were significantly associated with patient survival. Multivariate analysis using a method of stepwise selection revealed that presence or absence of distant metastasis is the most significant determinant (p < 0.0001) for survival, followed by venous involvement (p < 0.001), treatment period (p < 0.02) and local invasion (p < 0.02), in this order. A four-factor model of the above determinants yielded adjusted hazard ratios of 5.3 for distant metastasis (positive vs. negative), 3.7 for venous involvement (pV1a-pV2 vs. pV0), 3.9 for treatment period (1980-1984 vs. 1985-1991), and 3.1 for local invasion (pT3-pT4 vs. pT1-pT2). The present study revealed recent improvements in the patient survival and justified the clinical application of Robson's staging system implying local invasion, venous thrombus formation and distant metastasis as prognostic determinants.

One hundred and five patients with renal pelvic and ureteral tumor entered our treatment program between 1982 and 1991. Of 105 patients, 81 had resectable transitional cell carcinoma and were treated with radical or total nephroureterectomy (57 vs. 24) and/or lymph node dissection (66). Adjuvant chemotherapy was added in 26 patients with high stage disease and with lymph node disease. There were 61 male and 20 female patients. Their ages ranged from 36 to 86 years, with a mean of 62 years. The follow-up period was 3 to 114 months, with a mean of 31 months. The estimated 5-year survival was 67% in all 81 patients. Classified according to the pathological stage, 5-year survival was 70% in pTis + pTa disease group, 91% in pT1 group, 88% in pT2 group, 53% in pT3 group, and 27% in pT4 group. Under the grading system, 5-year survival was 100% in grade 1 disease, 74% in grade 2, and 26% in grade 3. It was 78% in 52 patients with negative node disease and 26% in 15 with positive node disease. There were 51 patients (61%) with no recurrent disease. Seventeen patients (21%) had recurrence in the bladder after a median latent period of 8-month, and 15 (19%) patients had recurrence in the retroperitoneum, liver, lung and (or) other site after a median latent period of 8 months. The results of this series were quite similar to those of previous reports. The efficacy of lymph node dissection and adjuvant chemotherapy could not be confirmed.

Between September, 1987 and September, 1993, a total of 44 consecutive patients had undergone radical retropubic prostatectomy and pelvic lymphadenectomy for the treatment of prostate cancer. The patients were between 56 and 77 years (mean, 68 years). Eleven patients had clinical state A2 disease, 21 had stage B disease, and 12 had stage C disease. Fourteen of the 44 patients (32%) had positive lymph node metastases. The 5-year survival rate for patients with pT1, pT2 and pT3 was 100%, 71% and 87%, respectively. It was 77% in patients with positive node disease and 90% in patients with negative node disease. The 5-year disease-free survival rate for patients with pT1, pT2 and pT3 was 82%, and 78%, respectively. It was 54% in patients with positive node disease and 88% in patients with negative node disease. In 14 positive node patients, metastases were located in obturater nodes in 8 patients (57%), hypogastric nodes, in 6 patients (43%), external iliac nodes in 6 patients (43%), common iliac nodes in 4 patients (29%) and presacral nodes in 2 patients (14%). We confirmed that radical retropubic prostatectomy is effective treatment for locally confined prostate cancer and removal of obturater, hypogastric lymph nodes and the internal chain of external iliac lymph nodes is important in detecting metastases.

Herein, we report two cases of squamous cell carcinoma of the ureter. The first case was in a 56-year-old-male. Total cystectomy and ileal conduit were performed because of bladder tumor suspected to be accompanied by carcinoma in situ and atrophic urinary bladder induced by chronic cystitis in December, 1993. Pathological examination revealed transitional cell carcinoma (TCC) > squamous cell carcinoma (SCC), G2 > G1, INF beta, pT1, 1y1, v1. He complained of back pain under medical observation in December, 1994. Left hydronephrosis was found and antegrade pyelography showed leakage from the left pelvic ureteral junction. Urinary cytology revealed class V and suggested TCC. He received left nephroureterectomy, and pathohistological examination of resected specimen revealed SCC, INF gamma, pT3, pRo, pLx, pVx, pNo, pMo. CABO chemotherapy (cisplatin, methotrexate, bleomycin, vincristine) was performed postoperatively. The second case was in a 61-year-old female. She complained of macrohematuria in the course of observation of pyelonephritis. Drip infusion pyelography showed right hydronephrosis and retrograde ureterogram revealed stenosis of the right lower ureter. Urinary cytology revealed class V. Nephroureterectomy and bladder cuff were performed. The tumor was histologically diagnosed as SCC > TCC, INF beta, pT3, pRo, pLo, pVo, pNo, pMo. Postoperatively, CABO chemotherapy was performed. So far, no recurrence has been observed. Fifty five cases of squamous cell carcinoma of ureter were collected from the Japanese literatures including our cases.
