Pregnancy and breast cancer: a population-based study.

The incidence of pregnancy-associated breast cancer, i.e. during pregnancy and lactation, and of pregnancy subsequent to a breast-cancer diagnosis will increase as more women choose childbearing at a later age. Few larger series are published on pregnancy-associated breast cancer. In a population-based study, we evaluated the outcome and prognostic factors in 173 breast-cancer patients. One hundred and twenty-two patients had pregnancy-associated breast cancer (20 coincident with pregnancy and 102 during lactation) and 51 patients had pregnancy subsequent to breast cancer. The median follow-up time was 151 months. Histopathological parameters and immunoreactivity for oestrogen and progesterone receptors c-erbB-2 and c-erbB-4 were studied. All three groups had tumours with high histological grade, low frequency of hormone receptors and high expression of c-erbB-2. The pregnancy and lactation groups were near identical with regard to all histopathological parameters and outcome. In the two pregnancy-associated breast-cancer groups, tumours were significantly larger, with more extensive lymph-node involvement. For node-negative tumours the respective 5- and 10-year survival rates were 62% and 50% in the pregnancy group and 60% and 50% in the lactation group. For node-positive tumours, respective 5- and 10-year survival rates were 50% and 34% in the pregnancy group and 50% and 33% in the lactation group. In the subsequent group, overall survival was high in both node-negative and -positive groups, with 5- and 10-year survival rates of 80% and 73% and 86% and 76%, respectively. Tumour size, lymph-node status, histological grade, progesterone receptor, oestrogen receptor and c-erbB-2 were significant prognostic factors in the pregnancy-associated breast-cancer patients.

[Cancer and religiosity--a follow up of patients with Hodgkin's disease]. / Kreft og religiøsitet--en etterundersøkelse av pasienter med Hodgkins sykdom.

In this study of religiosity among cancer patients and the relationship between religiosity and illness, a questionnaire was sent to 183 survivors of Hodgkin's disease in November 1995, all of them patients treated at the Norwegian Radium Hospital between 1988 and 1994. 107 patients (58%) gave replies to 45 questions relating to religion and belief, view of life, quality of life, and the relationship between religiosity and illness. The patients' attitude to religion differed little from that of the Norwegian population at large. 15% of the patients defined themselves as atheists, 14% as agnostics, 23% believed in God as an impersonal supreme power, and 48% in a personal God. 40 patients (38%) had changed their religious belief, 33 of them becoming more religious. 58% had prayed to God (or a supreme power) for cure. Half of the respondents felt that their religious belief had been a support during their illness. 52 (49%) were not satisfied with the pastoral services during hospitalisation. The study indicates that cancer disease activates religiosity, and that religiosity may help patients cope with their disease.

The prognostic value of p53 and c-erb B-2 immunostaining is overrated for patients with lymph node negative breast carcinoma: a multivariate analysis of prognostic factors in 613 patients with a follow-up of 14-30 years.

BACKGROUND: Approximately 30% of breast carcinoma patients with negative lymph nodes die of their disease. Biologic markers such p53 protein and c-erb B-2 have been related to tumor progression, but their prognostic value remains controversial. METHODS: Two large series of a total of 613 lymph node negative breast carcinoma patients from a single institution were analyzed with respect to tumor size, histologic grade, and immunohistochemical staining for p53, c-erb B-2, estrogen receptor (ER), and progesterone receptor (PgR). Interobserver variation in histologic grading was evaluated by Kappa statistics. The two series had different treatment modalities: 228 patients (SACGS group) were treated surgically with mastectomy and given 1 perioperative chemotherapy course, and 385 patients (HOST group) were treated with mastectomy and ovarian radiation and further randomized to receive postoperative treatment with radiotherapy or no adjuvant treatment. The follow-up ranged from 14-30 years. RESULTS: Immunoreactivities for p53, c-erb B-2, ER, and PgR did not differ significantly in the two series. p53 immunostaining was present in 187 of 613 tumors (29%), and c-erb B-2 immunoreactivity was present in 58 of the tumors (10%). Three hundred forty-eight tumors (57%) were positive for ER. Kappa statistics value of interobserver variation in the histologic grading of ductal carcinomas was 0.69, which is considered to be a substantial degree of agreement. No significant differences in survival were found when comparing p53, c-erb B-2, ER, and PgR positive and negative cases. However, both recurrence free survival rates and overall survival rates after 10 years were significantly better in the T1N0M0 group compared with the T2N0M0 group (81% vs. 67% [P < 0.0001] and 85% vs. 70% [P < 0.0001]). Ten-year recurrence free survival rates for patients with histologic Grade 1 versus Grades 2-3 (according to Elston and Ellis' modification of the Bloom and Richardson method) tumors were 90% and 70%, respectively (P < 0. 0001), and overall survival rates for the same groups were 94% and 81%, respectively (P=0.0002). After 30 years of follow-up, the overall survival rate for patients with tumors of histologic Grade 1 versus Grades 2-3 were 87% and 68%, respectively, and were 78% and 66%, respectively, for patients with tumors 20-50 mm. Approximately 35% of the patients with tumors of histologic Grades 2-3 and measuring > 20 mm were dead after 10 years of follow-up, contrary to 6% of the patients with tumors of histologic Grade 1 measuring

Elevated levels of p27, p21 and cyclin D1 correlate with positive oestrogen and progesterone receptor status in node-negative breast carcinoma patients.

The search for better prognostic indicators and new treatment modalities in node-negative breast carcinoma patients is important. The aim of this study was to determine the immunohistochemical expression of central cell regulator proteins in relation to hormone receptor status, tumour-cell differentiation and prognosis. We investigated the immunoreactivity of p27, p21, cdk4, cyclin D1 and p53 in 77 node-negative breast carcinomas, with long-term follow-up (mean 163 months; range 20-227). Nuclear staining for p27 was seen in 87% of the carcinomas, for cdk4 in 92%, for p21 in 68%, for cyclin D1 in 58% and for p53 in 18%. Oestrogen receptor (ER) and progesterone receptor (PgR) nuclear staining was seen in 69% and 65% of the tumours, respectively. No correlation between the levels of p21 and p53 was observed. p21 overexpression was, however, associated with positive ER status. Elevated levels of p27 and cyclin D1 correlated with positive hormone status (both ER and PgR). We did find a significant correlation between p27 and cyclin D1 and histological grade of the tumours, with extensive positive immunostaining of p27 and cyclin D1 in well-differentiated carcinomas. The only significant prognostic factor in our series was histological grading. Ten-year relapse-free survival was significantly prolonged in patients with histological grade I tumours versus histological grade II and III tumours. Our results suggest that the expression of p27 and cyclin D1 is closely linked to hormone receptor status in breast carcinomas and to tumour differentiation, a finding that may be of importance in the treatment of hormone-dependent tumours.

Late medical sequelae after therapy for supradiaphragmatic Hodgkin's disease.

A total of 221 consecutive early stage Hodgkin's disease (HD) patients were given mantle field irradiation only or in combination with chemotherapy in 1971-1991. In 1994 these patients responded to a mailed self-report questionnaire covering items on late medical symptoms. Of 200 patients (91%) who reported that their thyroid function had been tested, 110 patients (55% of those tested) had thyroid hypofunction at follow-up in 1994. Ninety-five patients (86% of patients with biochemical hypothyreosis) had started hormonal substitution. In 1993 and 1994, 101 of these patients who had received mantle field irradiation in 1980-1988 were called in for interview, clinical examination and thyroid function tests. Eighteen patients (18%) had started hormonal substitution treatment earlier, but 58 (70%) of the other 83 patients were found to have biochemical hypothyreosis. Of the 221 patients who completed the questionnaire, 66 patients (30%) reported dyspnoea on exertion for more than 3 years after treatment, 8 patients (4%) reported a history of myocardial infarction, 6 patients (3%) reported pericardial disease and 25 patients (11%) heart valve disease. Increased expenses incurred for dental care were reported by 106 patients (48%), increasing to 55% when Waldeyer's ring had been irradiated. The consequences of late sequelae after mantle field irradiation for future treatment are discussed.

Synovial sarcoma. Evaluation of prognosis with emphasis on the study of DNA ploidy and proliferation (PCNA and Ki-67) markers.

Controversy still exists regarding the validity of parameters commonly used in the evaluation of prognosis of patients with synovial sarcoma (SS). Forty-nine cases of previously untreated primary SS (23 females and 26 males, ranging in age from 7 to 81, with 31 tumors located in the lower extremity, 8 at the upper extremity and 10 at the trunchus), without regional lymph-node or distant metastases were studied. We investigated the relationship between (flow and image) DNA cytometry, proliferation activity, clinicopathologic parameters, and relapse-free and overall survival of the patients. The prognostic value of gender, age, duration of symptoms, location, compartmentalization, size, adequacy of surgical margins, residual tumor, adjuvant therapy, histologic subtype, extent of necrosis, glandular differentiation, calcification, and extent of hemangiopericytic areas, mitotic rate, amount of mast cells, blood vessel invasion, histologic (UICC and NCI) grades, DNA ploidy, percentage of cells in S and S+G2 phases, PCNA and Ki-67 labeling indices (LI), and TNM (UICC) stage of the tumors, were evaluated by univariate and multivariate (Cox hazard model) analyses. Short duration of symptoms (<12 months), biphasic SS, scarcity of mast cells (<10/10 HPF), high mitotic rate (> or =10/10 HPF), high histologic grade (grade 3), high PCNA-LI (> or =20%), high Ki-67-LI (> or =10%), DNA aneuploidy, and advanced TNM stage (stage III) were features associated with significantly shorter relapse-free and overall 5-year survival rates in the univariate analyses. Scarcity of mast cells, high mitotic rate, or high PCNA-LI were significant predictors of poor survival, in addition to TNM stage in the multivariate analyses. The amount of mast cells was inversely correlated with mitotic rate and PCNA-LI. Scarcity of mast cells, high mitotic rate, or high PCNA-LI are factors associated with poor prognosis, in addition to advanced TNM stage in patients with localized SS.

Socio-medical situation for long-term survivors of Hodgkin's disease: a survey of 459 patients treated at one institution.

We present the socio-medical situation for 459 adult disease-free long-term survivors of Hodgkin's disease (HD) 3-23 years after first line curative treatment. In 1994, 557 patients were sent a self-report questionnaire relating to their social status and 459 patients (82%) replied. Educational or professional plans were changed due to HD in 142 patients (32%). After 6, 12 and 18 months from start of treatment, 52, 82 and 95% of the patients, respectively, had returned to their job or education. The sum of full-time and part-time employment was in men 78% at diagnosis and 85% at follow-up, and in women 57% at diagnosis and 64% at follow-up. Only 2% of men and 3% of women did not have a job at follow-up in 1994. At diagnosis 2% of the patients were permanently disabled versus 19% at follow-up in 1994. Age > 40 years at diagnosis, increased the total score of psychological distress and fatigue and long-term disablement after first line treatment were predictors for permanent disablement. Transient or permanent sexual problems were reported in 16% and 13%, respectively. MVPP (mustine, vinblastine, procarbazine and prednisone) or LVPP (chlorambucil, vinblastine, procarbazine and prednisone) chemotherapy was responsible for most cases of early menopause in women older than 30 years, and of infertility in both men and women. In summary, most long-term HD survivors had adapted well to their socio-medical situation except a high number of permanently disabled patients. By focusing more on factors predisposing for permanent disablement and early treatment for these, more patients may be helped to return to their job.

Ifosfamide and continuous infusion etoposide in advanced adult soft tissue sarcoma. A Scandinavian Sarcoma Group Phase II Study.

The purpose of this study was to evaluate tumour response and toxicity to ifosfamide and continuous infusion etoposide in metastatic or locally advanced soft tissue sarcoma, with dose escalations under G-CSF (granulocyte colony-stimulating factor) support. Of 92 eligible patients (median age 51 years), 85% had tumours of high-grade malignancy and 82% had metastatic disease. Chemotherapy, the baseline dose, consisted of etoposide 600 mg/m2 as a 72 h infusion and ifosfamide 1500 mg/ m2/day for 3 days, followed by G-CSF support (VIG regimen). Stepwise 10% dose escalations were performed depending on haematological toxicity. For patients considered operable after induction chemotherapy, surgical resection of all identifiable residual tumour was attempted. Complete and partial response rates were 11% and 31%, for an overall response rate of 42% (95% CI 31-52%). Forty-eight per cent of courses were dose escalated by a median of 20%. Complete responders had significantly higher, and patients with progressive disease had significantly lower, dose levels than other patients. None of 20 patients with liver metastases responded despite high dose levels. Compared to a preceding pilot study, the addition of G-CSF led to significantly higher dose levels, improved schedule adherence and less haematological toxicity, but no apparent increase in response rate. In view of the modest dose of ifosfamide applied in this study, it is possible that the prolonged infusion of etoposide made a significant contribution to the regimen's antitumour activity, although this can only be determined definitively in a randomised study.

Randomized controlled trial of postoperative radiotherapy and short-term time-scheduled 5-fluorouracil against surgery alone in the treatment of Dukes B and C rectal cancer. Norwegian Adjuvant Rectal Cancer Project Group.

BACKGROUND: The purpose of the present study was to investigate whether a 1-month regimen of postoperative radiotherapy combined with 5-fluorouracil could reduce the local recurrence rate and improve survival in patients with Dukes B and C rectal cancer. METHODS: One hundred and forty-four patients were randomized to surgery alone or surgery combined with postoperative radiotherapy (46 Gy) and bolus 5-fluorouracil 30 min before six of the radiotherapy fractions. One hundred and thirty-six patients were eligible. RESULTS: The adjuvant treatment was well tolerated. After an observation time of 4-8 years, patients in the adjuvant treatment group had a cumulative local recurrence rate of 12 per cent compared with 30 per cent in the group that had surgery only (P = 0.01). The 5-year recurrence-free and overall survival rate was 64 per cent in the adjuvant group compared with 46 per cent (P = 0.01) and 50 per cent (P = 0.05) respectively in the surgery group. The adjusted relative risk of recurrence and death for the adjuvant group was 0.48 (95 per cent confidence interval 0.28-0.82) and 0.56 (0.33-0.94) respectively. CONCLUSION: The 1-month postoperative combination regimen improved treatment results in patients with Dukes B and C rectal cancer, in terms of local recurrence rate, recurrence-free survival and overall survival, without serious side-effects.

[The project Better Cancer Care in Buskerud]. / Prosjektet Bedre kreftomsorg i Buskerud.

A project called Better cancer care in Buskerud was started in 1991 in the county of Buskerud, in Norway. The main objective was to improve the out-patient services for cancer patients at the central hospital. In this article we describe the activities at the out-patient clinic during the period 1991-1993. The clinic was staffed by two oncologists and two cancer nurses. A total of 8060 consultations were held with patients during the period. Breast cancer patients comprised the largest group (30%), followed by patients with gastrointestinal cancer (24%) or malignant lymphoma (13%). The hospital's Department of Surgery was particularly relieved to hand over the administration of chemotherapy. The number of patients who received radiotherapy at the nearest cancer centre did not increase, however, during the period. We conclude that the project in Buskerud was a success, and that most of the objectives were achieved.

[Check up of breast cancer stages 1 and 2]. / Kontroll av cancer mammae stadium 1 og 2.

We have studied the efficacy of investigations during follow-up of 430 operable node positive and node negative breast cancer patients. Median follow-up was eight years, and 128 patients had relapsed, 91 with metastatic disease. Eight blood analyses, chest X-ray, limited skeletal X-ray and bone scan examinations were undertaken at regular intervals. Of the patients who had relapsed, 59% had symptoms, 23% were detected by clinical examination and 18% were detected by blood analysis only. X-rays and scintigrams were of little value in proportion to the costs. The combination of three blood analyses was useful. An increase in sedimentation rate (ESR) of more than 10 mm/h, an increase in gamma-glutamyltransferase (GT) of 20 U/l and an increase in alkaline phosphatase (ALP) of 60 U/l or more. By using ESR, gamma-GT, ALP, history and clinical examination, costs could be reduced by 90% while maintaining adequate baseline screening for relapse.

Systemic pneumococcal disease after staging splenectomy for Hodgkin's disease 1969-1980 without pneumococcal vaccine protection: a follow-up study 1994.

We surveyed, during 1994, all 325 patients who underwent staging laparotomy with splenectomy for Hodgkin's disease in Norway 1969-80, before pneumococcal vaccine was available in this country. The patients were thus not immunized preoperatively. Of 162 patients (49.8%) who died before 1994, 8 (2.4% of the total study) died from pneumococcal septicaemia and 16 (6.2%) from infections totally. Of 163 patients (50.2%) who were alive in 1994, 158 cooperated and filled in a questionnaire: 22 had been hospitalized for serious infections; 2 with pneumococcal septicaemia, and 6 with pneumonia, although lacking a specified microbiological diagnosis. We observed 325 patients representing 4420 patient-years, 3066 patient-years among survivors and 1354 patient-years among the dead. This resulted in an incidence rate of systemic pneumococcal disease of 226 per 100,000 patient-years, which is a relative risk of 20.5 compared to the general Norwegian population during 1994. Septicaemia for these patients most often had an abrupt clinical start even for relapse-free individuals and occurred from 2 to 17 yr after splenectomy (mean 10 yr). The risk of developing an overwhelming pneumococcal septicaemia with high case-fatality in asplenic patients seems to persist for these patients at about the same level even 15-20 yr after splenectomy. Only 12.7% of the survivors had been given pneumococcal vaccine in the autumn of 1993. Despite the fact that medical journals and media in Norway focused upon the problem of pneumococcal disease in asplenic individuals in the autumn of 1993 and spring of 1994, a substantial proportion of these patients (55.3%) still remained unimmunized when interviewed in the autumn of 1994. None of our systemic pneumococcal disease patients was vaccinated. Our data underline the need for prophylactic immunization with effective vaccines against pneumococcal infection in splenectomized Hodgkin's disease patients.

Psychological distress after cancer cure: a survey of 459 Hodgkin's disease survivors.

To assess the levels of psychological distress and identify predictors of anxiety/depression caseness after cancer cure, a national population of 557 Hodgkin's disease (HD) survivors was surveyed. The respondents [204 women, 255 men, mean age 44 years (SD = 12)] returned a mailed questionnaire including The Hospital Anxiety and Depression Scale (HADS). Disease and treatment variables were based on the hospital records. A total of 27% had caseness scores (anxiety, 14.5%; depression, 4%; anxiety and depression, 8.5%). In a multiple logistic regression analysis, anxiety caseness was predicted by low educational status [OR (odds ratio) = 2.07, 95% CI = 1.02-4.22], observational period 7 years or longer (7-10 years: OR = 3.07, 95% CI = 1.26-7.47), combined irradiation and chemotherapy treatment (OR = 2.77, 95% CI = 1.17-6.54) and psychiatric symptoms before HD (OR = 2.55, 95% CI = 1.40-4.65) or during treatment (OR = 3.51, 95% CI = 2.08-5.90). Depression caseness was predicted by age (OR = 1.03, 95% CI = 1.00-1.06) and psychiatric symptoms before HD (OR = 5.1, 95% CI = 2.55-10.31) Anxiety cases are more prevalent than in the general Norwegian population, and were found to be most common 7-10 years after treatment. The most intensive treatment was associated with increased risk for anxiety caseness. The subjects experienced distress during treatment precedes difficulties in long-term adjustment. Focusing on these predictors during treatment and follow-up controls may improve long-term outcome.

Five-year followup of a prospective trial of radical cystectomy and neoadjuvant chemotherapy: Nordic Cystectomy Trial I. The Nordic Cooperative Bladder Cancer Study Group.

PURPOSE: Chemotherapy is widely used in patients with locally advanced bladder cancer but until now there has been no conclusive evidence that this therapy improves survival. The Nordic Cooperative Bladder Cancer Study Group conducted a randomized phase III study to assess the possible benefit of neoadjuvant chemotherapy in patients with bladder cancer undergoing radical cystectomy after short-term radiotherapy. MATERIALS AND METHODS: Our trial included 325 patients with locally advanced stage T1 grade 3 or stages T2 to T4aNXM0 bladder cancer allocated randomly into a chemotherapy or no chemotherapy group (control). The chemotherapy schedule consisted of 2 cycles of 70 mg./m.2 cisplatin and 30 mg./m.2 doxorubicin with a 3-week interval between the cycles. RESULTS: After 5 years the overall survival rate was 59% in the chemotherapy group and 51% in the control group (p = 0.1). The corresponding cancer specific survival rate was 64 and 54%, respectively. In regard to treatment, no difference was observed for stages T1 and T2 disease, while there was a 15% difference in overall survival for patients with stages T3 to T4a disease (p = 0.03). In a multivariate analysis only chemotherapy and T category emerged as independent prognostic factors. The relative death risk for patients who received chemotherapy was 0.69 (95% confidence interval 0.49 to 0.98) compared to the control group after adjustment for the other tested factors. CONCLUSIONS: Neoadjuvant chemotherapy seems to improve long-term survival after cystectomy in patients with stages T3 to T4a bladder carcinoma, while no survival benefit was found for stages T1 to T2 disease.

[Prognosis in primary tumors of the central nervous system. A patient material from the Norwegian Radium Hospital 1960-94]. / Prognosen ved primaere svulster i sentralnervesystemet. Det Norske Radiumhospitals pasientmateriale 1980-94.

We present the results of a retrospective survey of 1,218 patients treated at the Norwegian Radium Hospital during the years 1980-94 for primary tumours of the central nervous system. Median survival for patients with glioblastoma (n = 492) was 12 months, for patients with anaplastic astrocytoma (n = 83) 25 months, astrocytoma (n = 260) 95 months, oligodendroglioma (n = 85) 74 months, mixed glioma (n = 68) 65 months, and medulloblastoma (n = 53) 109 months. Median survival for patients with brain stem tumours (n = 37) was nine months, while 74% of patients with tumours in the pineal region (n = 38) survived for five years. The histology and localisation of the tumour, as well as age and functional status, are important prognostic factors for survival in patients with primary CNS tumours.

Clinical stage I and II Hodgkin's disease: long-term results of therapy without laparotomy. Experience at one institution.

BACKGROUND: We concluded a program in which we administered radiotherapy only to clinical stages I and II Hodgkin's disease patients at standard risk, with the addition of 4 cycles of combination chemotherapy before radiotherapy for high-risk patients. PATIENTS AND METHODS: From 1980 to 1991, 313 patients with clinical stages I or II Hodgkin's disease underwent treatment in our hospital. Fifty percent of the patients in groups previously identified as being at high risk for relapse received 4 cycles of combination chemotherapy before radiotherapy. The remaining half of the patients received radiotherapy only. RESULTS: Low- and high-risk patients aged 15-59 years had, respectively, complete remission (CR) rates of 97% and 94%, 5-year survivals of 95% and 91%, and 5-year freedom from relapse (FFR) rates of 78% and 89%. Older low- and high-risk groups had CR rates of 97% and 93%, 5-year survivals of 60% and 56% and 5-year FFR of 77% and 93%, respectively. CONCLUSION: Here we present our favorable results after treating standard-risk patients with clinical stages I and II Hodgkin's disease with radiotherapy only. With the addition of chemotherapy, the rate of relapse in the high-risk patients was reduced below that of the standard-risk patients. Overall survival was the same for the high- and standard-risk patients.

[Tumor size and histological grading of stage 1 breast cancer. Prognostic and therapeutic significance]. / Tumorstørrelse og histologisk gradering ved cancer mammae stadium 1. Prognostisk og terapeutisk betydning.

Systemic adjuvant therapy can improve the prognosis for breast cancer patients. In node negative disease most patients have a good prognosis with local therapy only. Therefore, identification of subgroups with higher risk of relapse is warranted in order to avoid overtreatment of a large number of patients. A total of 399 tumours from patients without axillary metastases, operated on in the years 1964-72, were measured preoperatively and graded according to a modified Scharff-Bloom-Richardson scheme. Patients with T2 (UICC) tumours and histologic grade 2 and 3, had a 3.3-fold relative risk of mortality from breast cancer compared with the rest of the patients. These patients should receive adjuvant systemic therapy.

Clinical research in a hospital--from the lone rider to teamwork.

Clinical research of high international standard is very demanding and requires clinical data of high quality, software, hardware and competence in research design and statistical treatment of data. Most busy clinicians have little time allocated for clinical research and this increases the need for a potent infrastructure. This paper describes how the Norwegian Radium Hospital, a specialized cancer hospital, has reorganized the clinical research process. This includes a new department, the Clinical Research Office, which serves the formal framework, a central Diagnosis Registry, clinical databases and multicentre studies. The department assists about 120 users, mainly clinicians. Installation of a network software package with over 10 programs has strongly provided an internal standardization, reduced the costs and saved clinicians a great deal of time. The hospital is building up about 40 diagnosis-specific clinical databases with up to 200 variables registered. These databases are shared by the treatment group and seem to be important tools for quality assurance. We conclude that the clinical research process benefits from a firm infrastructure facilitating teamwork through extensive use of modern information technology. We are now ready for the next phase, which is to work for a better external technical framework for cooperation with other institutions throughout the world.

Survival after curative treatment of muscle-invasive bladder cancer.

This retrospective study includes 534 patients who had curatively intended treatment for T2/T3/T4a bladder cancer at the Norwegian Radium Hospital during the period 1980-1990. Total cystectomy preceded by preoperative radiotherapy represented the treatment of choice in 263 patients (CysGr). High-dose radiotherapy was applied in 271 patients in whom total cystectomy could not be performed (RadGr). From 1985 neo-adjuvant cisplatin-based chemotherapy was increasingly used. The 5-year crude survival rate for all patients was 35% with 40% for CysGr and 22% for RadGr. In CysGr the 5-year survival rate was highest (63%) for patients with

Prognostic variables and results of salvage treatment in Hodgkin's disease.

Treatment results and prognostic variables were studied in 549 adult patients with Hodgkin's disease after first-line and salvage treatment. After first-line treatment, 479 out of 549 patients (87%) achieved complete remission (CR). During a mean observation time of 74 months, 99 patients (21%) relapsed. Sixty-nine patients (70% of relapsed patients) achieved a second CR. Variables predicting poor response (< CR) and shortened survival after first-line treatment were advanced disease, B-symptoms and age >60 years. In relapsing patients, age >60 years, relapse within 12 months and non-CR after relapse treatment predicted a poor prognosis, and none of these patients were alive after 10 years. Localized disease at diagnosis and relapse, and relapse later than 24 months predicted a good prognosis with 10-year survival after relapse of 68% and 57%, respectively. Patients with a second relapse had 5-year survival of 28% and 10-year survival of 14%. Based on the prognostic variables at first-line treatment and at relapse, selection of patients to more intensive treatment is discussed.
