Since 1985 a special work group involved in the coordination of hospital cancer registries in Germany (AKKK) has been collecting, storing and analysing data on tumour patients, received from cancer centres, oncological departments and specialised practices. The documentation of tumour patients is based, among other things, on information concerning localisation, histological findings and tumour spread. The data are stored in a central database administered by the work group. At present it contains data on approximately 500,000 oncological patients. In the period from 1987 to 1992, 56,013 initial entries were made concerning patients with urological tumours. Of these cases, tumours of the kidney (n = 11,424) constituted 20.4%. In 94.6% of the cases, histological investigation revealed a renal cell carcinoma-pT1: 5.8%; pT2: 53.6%, pT3: 37.2% and pT4: 3.4%. Tumours of the urinary bladder (n = 16,246) constituted 29.0% of all urological tumours. In 93.8% of the cases a transitional cell carcinoma was detected-pTis: 1.0%; pTa: 36.9%; pT1: 29.6%; pT2: 16.9%; pT3: 11.4%; pT4: 4.4%. Transitional cell carcinomas of the ureter or of the collecting system (n = 1,846) constituted 3.3% of the cases. The proportion of testicular tumours (n = 6,594) amounted to 11.8%; 53.6% of these germ-cell tumours (n = 6,281) were seminomas and 46.6% were non-seminomas. In all, 66.3% of the cases were lymph-node negative. Tumours of the prostate (n = 19,903) constituted 35.5% of the cases. In the period from 1987 to 1992, the proportion of lymph-node-positive prostate carcinomas decreased from 39.8% to 16.2%. The detailed analysis of these data shows how the hospital cancer registries can support the discussion regarding diagnosis and therapy of urological tumours.

Over a period of 20 years 84 papillary and 82 follicular carcinomas operated on by one surgeon and examined by one pathologist were documented prospectively, treated selectively, and followed for 1 to 20 years (median 7 years). Tumors with a low risk of recurrence or incurable disease-i.e., papillary carcinoma pT1-3 N0 M0 (n = 56) and minimally invasive follicular carcinoma (n = 37)-were treated by a limited-radicality hemithyroidectomy or total thyroidectomy without radioiodine in 79 of the 93 cases (85%). No unfavorable course was observed, and only one curable recurrence (1.3%) developed contralaterally after hemithyroidectomy for papillary cancer. Of the remaining 73 patients, including 100% of those with nodal involvement, 65 (89%) underwent total thyroidectomy with radioiodine. Total thyroidectomy was achieved in 34% of the cases by completion thyroidectomy, based on definitive histologic examination. No instance of a serious, potentially incurable recurrence and no tumor-related death was observed in patients with a papillary TNM stage I+II or with a minimally invasive follicular carcinoma. Five of the patients (6%) with papillary carcinoma, all with TNM stage III or IV, and seven of the patients (8.5%) with follicular carcinoma, all grossly invasive and pT3 or pT4, had tumor-related deaths following total thyroidectomy in all and with remnant ablation in 10 cases. A potentially curable node recurrence occurred in two patients 1 and 10 years, respectively, after primary treatment. Permanent hypoparathyroidism (n = 4) (2.4%) and permanent recurrent laryngeal nerve palsy (n = 2) (1.2%) were observed only in patients with a grossly invasive follicular carcinoma and concomitant benign recurrent goiter. We conclude that (1) hemithyroidectomy or total thyroidectomy without radioiodine is adequate for papillary carcinoma pT1-3 N0 and minimally invasive follicular carcinoma; (2) there were no nodal recurrences in tumors recognized as node-negative; and (3) extracapsular excision of one or both lobes can be carried out technically with low morbidity. The study confirms the prognostic value of age-related TNM classification for papillary carcinoma; classification of follicular thyroid carcinoma as minimally invasive or grossly invasive proved to be useful.

We reviewed 954 primary nonurothelial epithelial renal neoplasms with primary resection at Memorial Sloan-Kettering Cancer Center between the years 1980 and 1995 and classified 70 cases (7%) as renal oncocytomas. The study population was composed of 39 men and 31 women, and the mean age was 65 years (range 25 to 86 years). Fifty-six patients (80%) were asymptomatic at presentation, six (4%) had flank pain, six (4%) presented with a mass, and two (3%) had hematuria. Sixty-one were treated with total or radical nephrectomy, nine with partial nephrectomy. The right kidney was involved in 35 cases (50%), the left kidney in 32 (46%). Three cases (4%) were bilateral. Sixty-one cases (87%) were unifocal, nine (13%) multifocal. All the tumors were well circumscribed but unencapsulated. Forty-five (64%) were described as brown or red, whereas the remainder were variously described as tan to yellow. Central fibrosis or scar was described in 23 cases (33%), and gross areas of hemorrhage or cystic changes in 14 (20%). The mean size was 5.2 cm and median 5.0 cm (range 1.5 cm to 14 cm). Histologically, the tumors were characterized by a mixture of architectural patterns: compact cellular nests and acini embedded in a hyalinized, hypocellular stroma were present in 62 cases (89%), a solid nested architecture in 47 cases (67%), and a variable tubular component in 50 cases (71%). Small papillae, pseudopapillae, and intratubular epithelial tufts were seen in 19 cases (27%). Cytologically, the neoplasms also showed a mixture of cell types, the most common being the classic oncocyte, which consisted of round or polygonal cells with moderate to abundant granular, eosinophilic cytoplasm, and small round nuclei with evenly dispersed granular chromatin. Small basophilic nucleoli were visible in many of these cells in all cases. Thirty-one cases (44%) had a variable number of oncocytic cells with pyknotic nuclei and 20 (30%) contained clusters of small cells with a high nuclear/cytoplasmic ratio and dense hyperchromatic nuclei (so-called oncoblasts). Foci of tubules with clear cells embedded in a hyalinized stroma were present in six cases (9%). Cellular atypia was evident in 42 cases (60%) and was marked in 21 (30%). Eleven cases (16%) exhibited mitotic activity, albeit low. No case had atypical mitoses or necrosis. Twenty-two cases (31%) had areas of calcification within the hyalinized stroma, 12 (17%) had calcospherites, and three (4%) had osseous and myeloid metaplasia. Vascular invasion was present in three cases (4%), and invasion of perinephric fat in 14 (20%). One patient presented with liver metastasis. Fourteen cases (20%) were pT1, 42 (60%) pT2, and 14 (20%) pT3. After a mean follow-up of 58 months (range 1 to 181), 62 patients (89%) were alive with no evidence of tumor, six (9%) had died of other causes, one was alive with stable metastatic disease in the liver 58 months after diagnosis, and one died with metastatic disease to bone and liver. We conclude that renal oncocytomas have a varied morphologic appearance and their pathologic diagnosis should be based on a constellation of architectural and cytologic features. The overwhelming majority of cases behave in a benign fashion, although in rare instances they can metastasize. The presence of atypical morphologic features do not alter the excellent prognosis associated with oncocytomas and do not predict an aggressive clinical course.

There is no debate that both the earlier diagnosis and the treatment of men with cancer of the prostate (CaP) are having an impact on patients with this disease. In many practices there are fewer and fewer patients presenting with the classic diagnosis of 'advanced disease', i.e., stage M (D2). Only a few years ago, a large percentage of men with CaP had bony metastases when they presented to a physician. Hormonal ablation was the optimal treatment, and the only question was whether bilateral orchiectomy or medical castration should be used. The median time to progression with either type of monotherapy was 12-18 months, and the median time to survival was 24-36 months. Unfortunately, in many parts of the world, this scenario is still the norm. In the United States, Europe, and an increasing number of other countries, improved methods of detection with transrectal ultrasound and prostate-specific antigen (PSA) have resulted in a dramatic shift in the stage of disease at diagnosis. It is safe to say that in these countries the majority of prostate cancers are now being clinically diagnosed while still localized, and many organ-confined tumors are being definitively treated and cured. Nevertheless, many of these patients will be understaged at the time of diagnosis and will show progression following definitive therapy. In most surgical series approximately one half of patients will be found on pathologic examination to have pT3 disease. The use of PSA in the diagnosis of CaP has been mentioned, and it is being used extensively to monitor recurrent/residual disease. Hormonal therapy is being employed earlier in numerous clinical situations, and its use is no longer reserved solely for patients with metastatic disease. In this context combined androgen blockade has become the gold standard of treatment in neoadjuvant situations as well as for advanced CaP. Newer advances, including 3-month depot formulations of luteinizing hormone-releasing hormone analogues, the reversibility of medical castration, the preference of most patients to have medical castration, and the approval of other antiandrogens in the United States, all have further strengthened the use of combined androgen blockade. Hormonal therapy in adjuvant settings, when there is a high likelihood of disease recurrence, is also being used in many clinical situations. In addition, there appears to be a role for certain types of hormonal therapy in chemoprevention.

Between 1989 and 1991, 815 cases of prostatic carcinoma were registered in the Tokai Urological Cancer Registry. We investigated the clinical features and prognosis of 69 patients who underwent radical prostatectomy. The median age and clinical stage, were 65.9 +/- 4.7 years and A in 7 patients, 66.3 +/- 5.8 years and B in 31, 68.2 +/- 2.7 years and C in 26, 63.4 +/- 13.5 years and N(+) in 5. Neoadjuvant therapy consisting of endocrine therapy and chemoendocrine therapy was administered to 28 and 14 patients, respectively. In comparison to the clinical stage, pathologically, 4 cases (9.5%) showed downstaging or overstaging, 15 (35.7%) understaging and 23 (54.8%) accurate staging in the neoadjuvant therapy group, and, respectively, 2 (7.4%), 12 (44.4%) and 13 (48.2%) in the non-neoadjuvant therapy group. There was a significant difference in the pretreatment prostatic antigen (PA) value between pT0 and pT3 (p < 0.05), between pT0 and pN(+) (p < 0.01) and between pT2 and pN(+) (p < 0.05). In addition, the pretreatment PA value in the recurrence group was higher than that in the non-recurrence group in both neoadjuvant and non-neoadjuvant groups, with a significant difference (p < 0.01) in the neoadjuvant group. Cancer recurrence was noticed in 2 patients given non-neoadjuvant therapy and 3 given neoadjuvant therapy. There was no significant difference in the non-recurrence rate with the pathological stage either with or without neoadjuvant therapy. However, the non-recurrence rate in the neoadjuvant therapy group was higher than that in the non-neoadjuvant therapy group.

The objective was to evaluate the results of a combination of surgery and postoperative radiotherapy in patients with uterine sarcoma, to describe the patterns of relapse and to define prognostic factors. From 1980 to 1993, 29 patients (median age: 56 years) presenting with uterine sarcoma have been treated with surgery and postoperative irradiation. The histology was: leiomyosarcoma: 11; carcinosarcoma: 12; stromal sarcoma: 6. The distribution by stage was: pT1: 18; pT2: 5; pT3: 3; pT4: 3; pNO: 27; pN1: 2. Gross residual disease was present in 4 patients. External beam irradiation was performed in all the cases and brachytherapy in 19. Chemotherapy was given in 3 patients. The overall survival rate was 66% at 2 years and 57% at 5 years with a disease free survival of 54% at 2 years and 50% at 5 years. Seven patients relapsed locally and 8 developed metastases. One patient died of ileitis. In a multivariate analysis, the disease free survival was strongly influenced by the menopausal status. The survival in this study is higher than that described in series of patients treated with surgery alone. This study confirms the worse prognosis of uterine sarcoma in postmenopausal women.

From 1981 to 1990, 1003 stage I-II breast cancers underwent surgery at the Division of Surgical Oncology of National Institute for Cancer Research of Genoa. This study described the clinical and pathologic features of these breast cancers. Radical mastectomy was performed in 73.8% of cases and conservative surgery in 26.2% of cases. In the last years the number of conservative treatment has increased. Related to size of tumour, in 1991 80.4% of pT1 performed a conservative surgery. The choice of type of surgery for pT2 tumours depended on the choice of patient and the ratio breast size and tumour size. The five-year overall survival was 85.8% in the group of conservative surgery and 65.3% in the group of radical surgery. The overall survival and relapse free survival have been calculated by Kaplan-Meyer method. Actuarial survival curves were computed according to type of surgery, tumor size, nodal status, hormonal receptors. In our experience the size of tumour was an important prognostic factor. The five years, overall survival was 80.7% in pT1 tumours and 67% in pT2-pT3 tumours (p = 10(-6)). The five-year overall survival in negative nodes patients was 80.5%. Conversely in patients with more than ten nodal metastases was 29.5%. The data reported in the present study were no different as in previous studies.

Preservation of the pelvic plexus in surgery for rectal cancer could shorten the distance between the cancer and the lateral resection margin, whereby the curability of the operation may be reduced. To clarify the indications for preserving the pelvic plexus in such surgery, the relationship of the pelvic plexus to the rectum and rectal cancer was investigated anatomically in 12 autopsied specimens and 12 surgical specimens. The rectum and anus were dissected with all the pelvic organs from autopsied cadavers and transverse sections were prepared at 10-mm intervals after fixation. The location of the pelvic plexus was then measured on the tissue preparations, and compared to that of surgical specimens from rectal cancers with concurrent resection of the pelvic plexus. The pelvic plexus was located from 3.3 +/- 1.2 cm above to 2.3 +/- 1.9 cm below the peritoneal reflection in the autopsied specimens. The average distances between the muscularis propria and the pelvic plexus in the autopsied specimens and surgical specimens were 8.3 +/- 3.5 mm and 14.7 +/- 4.5 mm, respectively, showing a significant difference (P < 0.05). Pelvic plexuses were located about 10 mm from the outer margin of rectal muscularis propria. These findings indicate that concurrent resection of the pelvic plexus may be required to secure sufficient surgical clearance in pT3 rectal cancers, especially those invading deeply beyond the muscularis propria (a2).

A retrospective review is presented of 1,942 consecutive patients with histopathologically confirmed invasive breast cancer, who where treated radically in Oslo from 1980 to 1989, either at General Municipal Hospitals (MH) or at a national Comprehensive Cancer Center (CC). The treatment and outcome were related to accepted medical parameters and the responsible hospital category. The median number of axillary lymph nodes described at the MH was 8, compared to 14 at the CC. During the period 1984 to 1986, 62% of the patients had an estrogen receptor analysis (MH 60%, CC 85%). Of the patients with N > or = 4, 36% received adjuvant hormone treatment (MH 32%, CC 67%), whereas the comparable percentage of patients with pT3/pT4 was 53%. The five- and ten-year cancer-related survival rates were 83% and 71% respectively, with no difference between the MH and the CC. As nation-wide criteria for the management of breast cancer have been accepted, compliance and monitoring by surgeons, pathologists and oncologists is imperative as part of quality assurance.

Adjuvant therapy after radical prostatectomy should ideally be limited to those patients at greatest risk for cancer recurrence, but identification of these patients remains a challenge. The local control rate in a group of 7494 patients undergoing radical prostatectomy for patients with pT2a disease of 76% is not different to pN+ disease of 80%. 95% of the pT3 patients were pN+ .90% of them received adjuvant treatment but only few patients with organ-confined cancer. A prognostic scoring system was created using the regression coefficients from the Cox multivariate model to classify patients with pathologically organ-confined prostate cancer according to risk of progression. Although tumor volume has traditionally been regarded as the most important prognostic factor in patients with localized prostate cancer, a recent multivariate analysis has shown that tumor volume is not an independent predictor. Moreover, accurate measurement of tumor volume is extremely difficult. Preoperative serum PSA levels, clinical stage, pathological grade and stage, and deoxyribonucleic acid (DNA) ploidy were evaluated by multivariate analysis to determine relative value in predicting treatment failure. Patients with the lowest score had a 92% progression free survival rate at 5 years, compared to only 39% of those with the highest scores. Patients believed to be at higher risk for cancer progression despite having organ confined disease might be targeted for adjuvant therapy and closer surveillance, while those at low risk may be followed less often.
