Computed Tomography and Conventional Radiography in Intrathoracic Metastases from Non-Seminomatous Testicular Tumor

Conventional chest radiographs and CT scans were studied retrospectively in 283 patients with untreated non-seminomatous testicular tumor. Intrathoracic metastases were found in 47 patients, and CT was the only positive examination in 20 of them. Lung metastases were seen in 39 patients and mediastinal lymph nodes were involved in 13. The additional yield of CT in detecting metastases was most marked for the lymph nodes (tumor detected only at CT in 9 out of 13 cases as compared with 14 out of 39 for the lung parenchyma). Posterior mediastinal and retrocrural lymph nodes were most often enlarged, and involvement of these was most difficult to detect at conventional radiography.

Characteristics of the case mix, organisation and delivery in cancer palliative care: a challenge for good-quality research

OBJECTIVES

Palliative care (PC) services and patients differ across countries. Data on PC delivery paired with medical and self-reported data are seldom reported. Aims were to describe (1) PC organisation and services in participating centres and (2) characteristics of patients in PC programmes.

METHODS

This was an international prospective multicentre study with a single web-based survey on PC organisation, services and academics and patients' self-reported symptoms collected at baseline and monthly thereafter, with concurrent registrations of medical data by healthcare providers. Participants were patients ≥18 enrolled in a PC programme.

RESULTS

30 centres in 12 countries participated; 24 hospitals, 4 hospices, 1 nursing home, 1 home-care service. 22 centres (73%) had PC in-house teams and inpatient and outpatient services. 20 centres (67%) had integral chemotherapy/radiotherapy services, and most (28/30) had access to general medical or oncology inpatient units. Physicians or nurses were present 24 hours/7 days in 50% and 60% of centres, respectively. 50 centres (50%) had professorships, and 12 centres (40%) had full-time/part-time research staff. Data were available on 1698 patients: 50% females; median age 66 (range 21-97); median Karnofsky score 70 (10-100); 1409 patients (83%) had metastatic/disseminated disease; tiredness and pain in the past 24 hours were most prominent. During follow-up, 1060 patients (62%) died; 450 (44%) <3 months from inclusion and 701 (68%) within 6 months. ANOVA and χ² tests showed that hospice/nursing home patients were significantly older, had poorer performance status and had shorter survival compared with hospital-patients (p<.0.001).

CONCLUSIONS

There is a wide variation in PC services and patients across Europe. Detailed characterisation is the first step in improving PC services and research.

TRIAL REGISTRATION NUMBER

ClinicalTrials.gov Identifier: NCT01362816.

A randomized phase III study comparing standard dose BEP with sequential high-dose cisplatin, etoposide, and ifosfamide (VIP) plus stem-cell support in males with poor-prognosis germ-cell cancer. An intergroup study of EORTC, GTCSG, and Grupo Germinal (EORTC 30974)

BACKGROUND

To compare the efficacy of one cycle of standard dose cisplatin, etoposide, and ifosfamide (VIP) plus three cycles of high-dose VIP followed by stem-cell infusion [high-dose chemotherapy (HD-CT arm)] to four cycles of standard cisplatin, etoposide, and bleomycin (BEP) in patients with poor-prognosis germ-cell cancer (GCC).

PATIENT AND METHODS

Patients with poor-prognosis GCC were assigned to receive either BEP or VIP followed by HD-CT. To show a 15% improvement in a 1-year failure-free survival (FFS), the study aimed to recruit 222 patients but closed with 137, due to slow accrual.

RESULTS

One hundred thirty-one patients were included in this analysis. The complete response rates in the HD-CT and in the BEP arm did not differ: (intention to treat) 44.6% versus 33.3% (P = 0.18). There was no difference in FFS between the two treatment arms (P = 0.057, 66 events). At 2 years, the FFS rate was 44.8% [95% confidence interval (CI) 32.5-56.4] and 58.2%, respectively (95% CI 48.0-71.9); but this 16.3% (standard deviation 7.5%) difference was not statistically significant (P = 0.060). Overall survival did not differ between the two groups (log-rank P > 0.1, 47 deaths).

CONCLUSION

This study could not demonstrate that high-dose chemotherapy given as part of first-line therapy improves outcome in patients with poor-prognosis GCC.

Classification of pain in cancer patients--a systematic literature review

One of the aims of the European Palliative Care Research Collaborative (EPCRC) is to achieve consensus on a classification system for cancer pain. We performed a systematic literature review to identify existing classification systems and domains/items used to classify cancer patients with pain. In a systematic search in the databases Medline and Embase, covering 1986-2006, 692 hits were obtained. 92 papers were evaluated to address pain classification. Six standardised classification systems were identified; three of them systematically developed and partially validated. Both pain characteristics and patient characteristics relevant for cancer pain classification were included in the classification systems. All but one of the standardised systems aim at predicting treatment response or adequacy of treatment. Several domains and items used to describe cancer pain but not formally described as part of a classification system were also identified and systematized. The existing approaches to pain classification in cancer patients are different, mostly not thoroughly validated, and none is widely applied. An internationally accepted classification system for cancer pain could improve research and cancer pain management. This systematic review suggests a need for developing an international consensus on how to classify pain in cancer patients.

Predicted cardiovascular mortality and reported cardiovascular morbidity in testicular cancer survivors

INTRODUCTION

We examined if testicular cancer (TC) treatment is associated with any risk for cardiovascular morbidity or predicted mortality according to the SCORE model, in which a 10-year future risk of >or=5% for developing a fatal cardiovascular event qualify for high-risk status.

METHODS

One thousand one hundred thirty-four TC survivors treated 1980-1994 participated in this study (1998-2002). Patients were categorised in four treatment groups: surgery (n = 225), radiotherapy (n = 445), and two chemotherapy groups: cumulative cisplatin dose <or=850 mg (n = 375) and >850 mg (cis>850, n = 89). Patients with cardiovascular disease, diabetes or SCORE >or=5% constituted a high-risk group, and those with SCORE >1% an intermediate/high risk group.

RESULTS

Age-adjusted mean SCORE was 0.93% for the surgery group. In comparison, chemotherapy treated patients had significantly higher SCORE (1.07%, p = 0.01). Only 15% of patients were scored to be at high-risk, while 53% qualified for the intermediate/high risk group. Patients in the cis>850 group had increased odds for having intermediate/high risk, compared with the surgery group (OR 3.4, 95% CI 1.3-8.7). Only 23 cardiovascular events had occurred since the testicular cancer diagnosis.

CONCLUSION

The SCORE model indicates that patients treated with cisplatin-based chemotherapy have a significantly increased future risk of a fatal cardiovascular event.

IMPLICATIONS FOR CANCER SURVIVORS

TC survivors should be followed regularly with respect to cardiovascular risk profile beyond the routine 10-year clinical follow-up.

Components of the metabolic syndrome in long-term survivors of testicular cancer

BACKGROUND

A possible explanation of the excess cardiovascular risk in testicular cancer (TC) survivors is development of metabolic syndrome. The association between metabolic syndrome and TC treatment is examined in long-term survivors.

PATIENTS AND METHODS

In a national follow-up study (1998-2002), 1463 TC survivors (diagnosed 1980-1994) participated. Patients >60 years were excluded in the present study, leaving 1135 patients eligible. The patients were divided in four treatment groups: surgery (n = 225); radiotherapy (n = 446) and two chemotherapy groups: cumulative cisplatin dose (Cis) <or=850 mg (n = 376) and Cis >850 mg (n = 88). A control group consisted of 1150 men from the Tromsø Population Study. Metabolic syndrome was defined according to a modified National Cholesterol Education Program definition.

RESULTS

Both chemotherapy groups had increased odds for metabolic syndrome compared with the surgery group, highest for the Cis >850 group [odds ratio (OR) 2.8, 95% confidence interval (CI) 1.6-4.7]. Also, the Cis >850 group had increased odds (OR 2.1, 95% CI 1.3-3.4) for metabolic syndrome compared with the control group. The association between metabolic syndrome and the Cis >850 group was strengthened after adjusting for testosterone, smoking, physical activity, education and family status.

CONCLUSION

TC survivors treated with cisplatin-based chemotherapy have an increased risk of developing metabolic syndrome compared with patients treated with other modalities or with controls.

Medical Research Council trial of 2 versus 5 CT scans in the surveillance of patients with stage I non-seminomatous germ cell tumours of the testis

4519

Background: Surveillance is a standard management approach for stage 1 non seminomatous germ cell tumours (NSGCT), yet there is no agreement on the number of CT scans that are required to detect relapses. A randomised trial of 2 versus 5 CT scans was performed to determine whether the number of scans influenced the prognostic group (J Clin Oncol 15:594–603, 1997) at relapse. Methods: Patients with clinical stage 1 NSGCT opting for surveillance were randomised to chest and abdominal CT scans at either 3 and 12 or 3, 6, 9, 12, and 24 months, with all other investigations (clinical exams, markers, chest X-rays) carried out at equal frequency in the two arms. 3/5 patients were allocated to the 2 scan schedule. 400 patients were required to exclude a 3% increase in the proportion of patients relapsing with IGCCCG intermediate or poor prognosis disease with 90% power at the 5% significance level (1-sided). Results: 247 patients were allocated to 2 CT scans and 167 to 5 CT scans. With a median follow up of 40 months 37 (15%) relapses have occurred in the 2 scan arm and 33 (20%) in the 5 scan arm. No patients were poor prognosis at relapse but 2 (0.8%) of those relapsing in the 2 scan arm were intermediate prognosis compared to 1 (0.6%) in the 5 scan arm a difference of 0.2% (90% CI −1.2%, +1.6%). The mean diameter of abdominal mass at relapse was 2.1 cm in the two scan arm and 2.2 cm in the five scan arm. After chemotherapy a residual mass was present in 35% in the 2 scan and 36% in the 5 scan arm. No deaths have been reported. Conclusions: This study can exclude with 95% probability an increase in the proportion of patients relapsing with intermediate or poor prognosis disease of more than 1.6% if they have 2 rather than 5 CT scans as part of their surveillance protocol. CT scans at 3 and 12 months after orchidectomy should be considered as the new standard and will be associated with a reduction in radiation exposure.

Blood pressure and body mass index in long-term survivors of testicular cancer

PURPOSE

To evaluate blood pressure and body mass index (BMI) in long-term survivors of testicular cancer (TC) treated with different modalities.

PATIENTS AND METHODS

One thousand eight hundred fourteen patients treated for unilateral TC in Norway (1980 to 1994) were invited to participate in a follow-up study (1998 to 2002), including measurements of systolic blood pressure (SBP), diastolic blood pressure (DBP), and BMI. Of these patients, 1,289 patients (71%) participated in the study. The patients were categorized into four treatment groups: surgery (n = 242), radiotherapy (n = 547), and two chemotherapy groups, cumulative cisplatin dose < or = 850 mg (n = 402) and cumulative cisplatin dose more than 850 mg (n = 98). A control group consisted of healthy males from the Tromsø Population Study (n = 2,847).

RESULTS

At diagnosis, age-adjusted regression analyses showed no differences between the treatment groups for any variables. After a median follow-up time of 11.2 years, age-adjusted SBP and DBP were significantly higher for both chemotherapy groups compared with the surgery group. Chemotherapy-treated patients had increased odds for hypertension at follow-up compared with the surgery group, and the odds were highest for the cisplatin more than 850 mg group (odds ratio = 2.4; 95% CI, 1.4 to 4.0). The cisplatin more than 850 mg group had a significantly higher 10-year BMI increase and a higher prevalence of obesity at follow-up than the surgery group. Compared with healthy controls, chemotherapy-treated patients had, at follow-up, increased SBP, increased DBP, excessive BMI increase, and a higher prevalence of hypertension.

CONCLUSION

Five to 20 years after therapy, cured TC patients treated with cisplatin-based chemotherapy had significantly higher levels of blood pressure, a higher prevalence of hypertension, and an excessive weight gain compared with patients treated with other modalities and compared with healthy controls.

Radiotherapy versus single-dose carboplatin in adjuvant treatment of stage I seminoma: a randomised trial

BACKGROUND

Adjuvant radiotherapy is effective treatment for stage I seminoma, but is associated with a risk of late non-germ-cell cancer and cardiovascular events. After good results in initial studies with one injection of carboplatin, we undertook a large randomised trial to compare the approaches of radiotherapy with chemotherapy in seminoma treatment.

METHODS

Between 1996 and 2001, 1477 patients from 70 hospitals in 14 countries were randomly assigned to receive radiotherapy (para-aortic strip or dog-leg field; n=904) or one injection of carboplatin (n=573; dose based on the formula 7x[glomerular filtration rate+25] mg), at two trial centres in the UK and Belgium. The primary outcome measure was the relapse-free rate, with the trial powered to exclude absolute differences in 2-year rates of more than 3%. Analysis was by intention to treat and per protocol. This trial has been assigned the International Standard Randomised Controlled Trial Number ISRCTN27163214.

FINDINGS

885 and 560 patients received radiotherapy and carboplatin, respectively. With a median follow-up of 4 years (IQR 3.0-4.9), relapse-free survival rates for radiotherapy and carboplatin were similar (96.7% [95% CI 95.3-97.7] vs 97.7% [96.0-98.6] at 2 years; 95.9% [94.4-97.1] vs 94.8% [92.5-96.4] at 3 years, respectively; hazard ratio 1.28 [90% CI 0.85-1.93], p=0.32). At 2 years' follow-up, the absolute differences in relapse-free rates (radiotherapy-chemotherapy) were -1.0% (90% CI -2.5 to 0.5) by direct comparison of proportions, and 0.9% (-0.5 to 3.0) by a hazard-ratio-based approach. Patients given carboplatin were less lethargic and less likely to take time off work than those given radiotherapy. New, second primary testicular germ-cell tumours were reported in ten patients allocated irradiation (all after para-aortic strip field) and two allocated carboplatin (5-year event rate 1.96% [95% CI 1.0-3.8] vs 0.54% [0.1-2.1], p=0.04). One seminoma-related death occurred after radiotherapy and none after carboplatin.

INTERPRETATION

This trial has shown the non-inferiority of carboplatin to radiotherapy in the treatment of stage I seminoma. Although the absence of disease-related deaths and preliminary data indicating fewer second primary testicular germ-cell tumours favour carboplatin use, these findings need to be confirmed beyond 4 years' follow-up.

European consensus on diagnosis and treatment of germ cell cancer: a report of the European Germ Cell Cancer Consensus Group (EGCCCG)

Germ cell tumour is the most frequent malignant tumour type in young men with a 100% rise in the incidence every 20 years. Despite this, the high sensitivity of germ cell tumours to platinum-based chemotherapy, together with radiation and surgical measures, leads to the high cure rate of > or = 99% in early stages and 90%, 75-80% and 50% in advanced disease with 'good', 'intermediate' and 'poor' prognostic criteria (IGCCCG classification), respectively. The high cure rate in patients with limited metastatic disease allows the reduction of overall treatment load, and therefore less acute and long-term toxicity, e.g. organ sparing surgery for specific cases, reduced dose and treatment volume of irradiation or substitution of node dissection by surveillance or adjuvant chemotherapy according to the presence or absence of vascular invasion. Thus, different treatment options according to prognostic factors including histology, stage and patient factors and possibilities of the treating centre as well may be used to define the treatment strategy which is definitively chosen for an individual patient. However, this strategy of reduction of treatment load as well as the treatment itself require very high expertise of the treating physician with careful management and follow-up and thorough cooperation by the patient as well to maintain the high rate for cure. Treatment decisions must be based on the available evidence which has been the basis for this consensus guideline delivering a clear proposal for diagnostic and treatment measures in each stage of gonadal and extragonadal germ cell tumour and individual clinical situations. Since this guideline is based on the highest evidence level available today, a deviation from these proposals should be a rare and justified exception.

Somatic mutations of KIT in familial testicular germ cell tumours

Somatic mutations of the KIT gene have been reported in mast cell diseases and gastrointestinal stromal tumours. Recently, they have also been found in mediastinal and testicular germ cell tumours (TGCTs), particularly in cases with bilateral disease. We screened the KIT coding sequence (except exon 1) for germline mutations in 240 pedigrees with two or more cases of TGCT. No germline mutations were found. Exons 10, 11 and 17 of KIT were examined for somatic mutations in 123 TGCT from 93 multiple-case testicular cancer families. Five somatic mutations were identified; four were missense amino-acid substitutions in exon 17 and one was a 12 bp in-frame deletion in exon 11. Two of seven TGCT from cases with bilateral disease carried KIT mutations compared with three out of 116 unilateral cases (P=0.026). The results indicate that somatic KIT mutations are implicated in the development of a minority of familial as well as sporadic TGCT. They also lend support to the hypothesis that KIT mutations primarily take place during embryogenesis such that primordial germ cells with KIT mutations are distributed to both testes.

Erroneous diagnosis of pancreatic cancer after radiotherapy of testicular cancer

BACKGROUND

After radiotherapy with or without chemotherapy radiation-induced normal tissue alteration may mimic cancer and may cause major morbidity.

RESULTS

Two patients irradiated for seminoma, in one case combined with cisplatin-based chemotherapy, developed clinical symptoms and radiological signs comparable to pancreatic cancer (stenosis of the ductus choledochus). The non-malignant diagnosis was finally established by revision of the histological specimen (case 1) and per-operatively (case 2). In both patients by-pass operations for biliary tract stenosis resulted in excellent palliation.

CONCLUSION

Radiation-induced fibrosis within the upper retroperitoneal space is an important differential diagnosis versus pancreatic cancer in patients with prior radiotherapy for seminoma. Diagnosis based only on clinical and radiological findings may lead to incorrect patient information and registration errors in Cancer Registries.

Increased mortality rates in young and middle-aged patients with malignant germ cell tumours

Cisplatin-based chemotherapy of malignant germ cell tumours (MGCT) has been reported to increase the risk of cardiovascular morbidity. A high incidence of second nongerm cell malignancies is well documented in MGCT survivors. The death risk due to these conditions is, however, more unknown in MGCT patients. Standard mortality rates (SMRs) were established in 3378 Norwegian MGCT patients treated from 1962 to 1997 aged ⩽55 years. The patients represented three principal treatment strategies: 1962/1969 (period 1): radiotherapy only; 1970/1979 (period 2): radiotherapy with or without noncisplatin-containing chemotherapy; 1980/1997 (period 3): surgery only or radiotherapy or cisplatin-based chemotherapy. Patients were censored when they reached the age of 60 years. Patients not dying from MGCT displayed significantly increased SMRs for respectively diseases of the circulatory system (SMR: 1.2, 95% confidence interval (CI): 1.0–1.5), benign gastrointestinal disorders (SMR: 2.1, 95% CI: 1.1–3.5) and nongerm cell malignancies (SMR: 2.0, 95% CI: 1.7–2.4). The SMRs for diseases of the circulatory system were similar in the three observation periods, whereas the highest SMR for benign gastrointestinal disorders was observed in patients from period 2. The risk of dying from a nongerm cell malignancy was increased both in periods 2 and 3. In conclusion, although the overall SMR for diseases of the circulatory system is increased in MCGT survivors, the introduction of cisplatin-based chemotherapy into the treatment of MGCT has so far not resulted in increased death rates due to these conditions. Patients with MGCT have a significantly increased relative death risk due to a second nongerm cell cancer, even after the introduction of modern treatment principles with overall reduction of radiotherapy. The increased death risk due to benign gastrointestinal disorders, probably related to radiotherapy, requires future in-depth analysis.

Testicular carcinoma in situ in patients with extragonadal germ-cell tumours: the clinical role of pretreatment biopsy

BACKGROUND

The aim of this study was to determine the prevalence of testicular carcinoma in situ (CIS) in patients with a malignant extragonadal germ-cell tumour (EGGCT) and the incidence of metachronous invasive testicular cancer (TC) in relation to the pretreatment demonstration of CIS.

PATIENTS AND METHODS

Sixty-eight patients with EGGCT (53 retroperitoneal, 15 mediastinal) had pre-chemotherapy histological assessment of one (13) or both (55) testicle(s). A total of 123 testicles were examined for the presence of CIS.

RESULTS

Testicular CIS was found in 21 patients (31%) (18 retroperitoneal EGGCT, three mediastinal EGGCT). Two patients had bilateral CIS. Five patients, four of them with proven pretreatment CIS, developed a metachronous TC. The 10-year invasive-free TC survival rate for all 68 patients was 88%, but only 65% for those with proven pretreatment CIS. The overall 10-year survival rate for all patients was 82%. CIS was demonstrated in seven of 48 trans-scrotal core biopsies, in 10 of 56 trans-scrotal surgical biopsies and in five of 11 orchiectomy specimens.

CONCLUSIONS

Approximately one-third of patients with EGGCT present with testicular CIS, predominantly those with a retroperitoneal tumour. These patients have a considerable risk of metachronous TC development in spite of chemotherapy. The pretreatment demonstration of testicular CIS in patients with EGGCT gives the possibility of individualised counselling and safe follow-up, and is therefore highly recommended. The data are in agreement with a multi-site development of malignant germ-cell tumours, but do not exclude the possibility that the retroperitoneal EGGCTs in particular represent metastases from a burned-out TC.

Intensive induction chemotherapy with CBOP/BEP in patients with poor prognosis germ cell tumors

PURPOSE

Despite a high cure rate in patients with testicular cancer, there remain patients in the poor prognosis group who have a less favorable outcome. Intensive induction chemotherapy using a regimen consisting of carboplatin, bleomycin, vincristine, and cisplatin, followed by bleomycin, etoposide, and cisplatin (CBOP/BEP), developed at the Royal Marsden Hospital, is designed to overcome the rapid proliferation seen in germ cell tumors. This study assesses the outcome of patients with poor-prognosis nonseminomatous germ cell tumors (NSGCT) treated with CBOP/BEP.

PATIENTS AND METHODS

Patients with NSGCT from three centers, classified as poor prognosis according to International Germ Cell Classification Consensus Group criteria, were treated with CBOP/BEP regimen during the period from 1989 to 2000. Data on treatment toxicity, relapse-free survival (RFS), and overall survival (OS) were collected prospectively on a hospital database.

RESULTS

Fifty-four male patients with poor prognosis NSGCT were treated with CBOP/BEP. The RFS at 3 and 5 years for all patients was 83.2% (95% confidence interval [CI], 68.8% to 91.3%). After a median follow-up of 4 years, the OS of the 54 patients was 91.5% (95% CI, 78.6% to 96.8%) at 3 years and 87.6% (95% CI, 71.3% to 94.9%) at 5 years. Three-year OS in patients with a primary mediastinal germ cell tumor was 77.1% (95% CI, 34.5% to 93.9%) compared with 95.4% (95% CI, 82.8% to 98.8%) in patients with a testicular primary tumor (P =.24).

CONCLUSION

The results reported here compare favorably with the historical results of alternative regimens used in the management of poor-prognosis NSGCT. We suggest a phase III trial to confirm our findings.

Long-term renal function after treatment for malignant germ-cell tumours

OBJECTIVE

To evaluate prospectively renal function in patients with malignant germ-cell tumours (MGCTs) >10 years after retroperitoneal lymph node dissection alone (RPLND), radiotherapy alone (RAD) or different schedules of cisplatin-based chemotherapy with or without surgery/radiotherapy (CHEM).

PATIENTS AND METHODS

In 85 patients, three groups were identified: RPLND, 14; RAD, 18; CHEM, 53, with subdivision of the latter group according to the cumulative cisplatin dose or the additional use of radiotherapy. Renal function was determined by 131Iodine Hippuran clearance or 99m DTPA glomerular filtration rate, and was assessed before treatment and four times during 14 years of follow-up. A value of <70% of the upper limit of the normal range identified impaired renal function.

RESULTS

Twenty-five patients displayed long-term impaired renal function, 23 of them from the RAD or CHEM group. In the RAD group, renal function decreased by 8%, whereas a 14% reduction of renal function was observed in the CHEM group. In the CHEM group the cumulative dose of cisplatin, and in the RAD group the age at treatment, were associated with impairment of renal function. Combining all patients, age at treatment and the type of treatment were associated with impaired renal function.

CONCLUSIONS

In 20-30% of the patients with germ-cell tumour, standard radiotherapy and chemotherapy strategies are followed by long-term subclinical impaired renal function. These findings support current intentions to avoid overtreatment with these treatment modalities.

False-negative biopsy for testicular intraepithelial neoplasia and high-risk features for testicular cancer

The purpose of this report is to emphasize the possibility of false-negative biopsies for testicular intraepithelial neoplasia (TIN) in men with high-risk features of testicular cancer and to review the relevant literature. At the Norwegian Radium Hospital patients in this category are offered the chance to undergo a testicular biopsy. A patient is described who had a normal testicular biopsy a decade before presenting with an invasive testicular cancer. Furthermore, this patient is the first case reported with a false-negative biopsy for TIN and a family history of testicular cancer. The evaluation of the biopsies included immunohistochemical staining for c-kit and PIAP (placental-like alkaline phosphatase) in order to diagnose early TIN. Though multifocal or diffuse extension seems to be the most frequent pattern of distribution of TIN, the presented case and another 14 cases from the literature review indicate that the focality of TIN may be a reason for a TIN-negative biopsy.

[Treatment of renal carcinoma with distant metastases]

BACKGROUND

There is no effective standard therapy for patients with distant metastases from renal cell carcinoma. Physicians should, however, know about the different treatment options and their efficacy in order to adequately inform and treat their patients.

MATERIAL AND METHODS

Current relevant literature and experience at the Norwegian Radium Hospital are reviewed with emphasis on systemic therapy.

RESULTS

Nephrectomy is indicated if the aim is to palliate or prevent local symptoms due to a large primary tumour, or if the operation renders a patient eligible for a clinical trial. Local symptoms due to metastatic lesions should be managed surgically or by radiotherapy. Hormone treatment and current chemotherapy are ineffective. In selected patients interferon-alpha (IFN-alpha) results in an approximately 15% response rate and 4-6 months' prolongation of life. Combination therapy with interleukins or with other drugs is experimental.

INTERPRETATION

Patients with metastatic renal cell carcinoma should primarily be included in clinical trials. If this is not possible, interferon-alpha monotherapy represents today's standard systemic treatment, to be offered to selected and informed patients.

Anxiety and depression in cancer patients: relation between the Hospital Anxiety and Depression Scale and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire

BACKGROUND

The emotional functioning (EF) dimension of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C33) and the Hospital Anxiety and Depression Scale (HADS) evaluate anxiety and depression. We wanted to compare cancer patients' responses to EF with those to HADS, as well as the impact of anxiety and depression on the quality of life (QL) dimensions of the EORTC QLQ C33.

METHOD

A total of 568 cancer patients completed both the EORTC QLQ C33 and HADS at the same occasion. The association between the patients' EF scorings and their HADS scores was analyzed by multiple linear regression. Gender and age were included as covariates.

RESULTS

Statistically significant negative relations were found between EF and HADS-A (anxiety), HADS-D (depression) and HADS-T (total score), respectively, with the highest correlation coefficient for HADS-A. Older patients and males reported less emotional distress assessed by the EF scale than younger ones and females with comparable HADS-T or HADS-D scores. Both HADS-A and HADS-D were significantly related to other QL dimensions, and depression was a stronger predictor for reduced QL than anxiety.

CONCLUSION

The EF dimension of EORTC QLQ C33 predominantly assesses anxiety, whereas depression is rated to a lesser degree. Combined with significant age and gender relations, this implies a risk of underdiagnosed depression, if the EORTC QLQ C33 is used as the only instrument to screen for psychological distress in cancer patients. As depression has a stronger impact on global QL of cancer patients than anxiety, the use of an additional instrument is recommended for assessment of depression.

Ejaculation in testicular cancer patients after post-chemotherapy retroperitoneal lymph node dissection

The purpose of this study was to evaluate fertility after different types of post-chemotherapy retroperitoneal lymph node dissection (RPLND). During 1980-1994, 192 patients with metastatic testicular cancer underwent post-chemotherapy RPLND with a gradual shift from modified bilateral template RPLND to nerve-sparing RPLND. Modified bilateral template RPLND was done in 92% of the patients operated during 1980-1984 as compared to 16% during 1989-1994. Pre- and post-treatment fertility was assessed by microscopic sperm analysis, determination of serum FSH and information on ejaculation and paternity. There was no significant difference of the survival rates between the three treatment periods. Antegrade ejaculation was preserved in 11% of the patients after modified bilateral template RPLND as compared to 89% after the nerve-sparing operation technique. The median ejaculatory volume decreased post-operatively, serum FSH increased and sperm density remained unchanged. Fifty-six patients attempted fatherhood after their treatment, and 27 fathered at least one child after an observation-time of 55 months, nine of them by assisted fertilization. Patients with initially advanced testicular cancer but limited residual retroperitoneal masses after induction chemotherapy can safely undergo limited post-chemotherapy RPLND as a part of multimodality treatment. After nerve-sparing RPLND antegrade ejaculation is preserved in 89% of the patients though the ejaculatory volume decreases after RPLND. Post-treatment fatherhood can be achieved in at least 50% of the patients attempting paternity.

A phase II study of DaunoXome in advanced urothelial transitional cell carcinoma

Liposomal encapsulation of anthracyclines is claimed to reduce toxicity and to improve pharmacokinetics. Therefore, 15 patients with locally advanced or metastatic transitional cell cancer (TCC) of the urinary tract were entered into a phase II study assessing the response rate (WHO criteria) and toxicity of DaunoXome 100 mg/m2 given as a 1 h infusion every third week. During treatment, 6 patients remained stable and 8 had progressive disease. 1 patient died of pulmonary embolism after the first cycle and was not evaluable for response. No patient developed grade 4 myelotoxicity. Grade 3 leucopenia was seen in 5 patients and grade 1 thrombocytopenia in 1 patient, with no treatment-related changes of biochemical liver and kidney function tests. 4 patients complained of angina pectoris-like chest pain during the initial phase of the first or second infusion. The event was associated with a decrease in systolic blood pressure by 20-30 mm in 1 patient leading to permanent treatment discontinuation. In the other 3 and all subsequent patients, intramuscular application of 100 mg hydrocortisone 1 h prior to DaunoXome infusion prevented similar hypotensive reactions. In this study, intravenous (i.v.) DaunoXome 100 mg/m2 every third week showed no anticancer activity in advanced TCC.

[Occurrence of anxiety and depression in cancer patients. An investigation at the Norwegian Radium Hospital]

The prevalence of anxiety and depression was evaluated in 716 unselected hospitalised patients and out-patients seen at the Norwegian Radium Hospital using the Hospital Anxiety and Depression Scale (HADS), the EORTC QLQ-C33 and an ad hoc designed questionnaire, the latter assessing socio-demographic data and disease-related parameters. The prevalence of anxiety and depression was 13% and 9%, respectively, as assessed with the HADS. In the logistic regression analysis, none of the disease-related factors remained independent parameters predictive for psychiatric distress, whereas a history of previous psychiatric problems and impaired social life were correlated both with anxiety and depression. Female gender, impaired physical activity and impaired social role function were additional predictive parameters for anxiety, whereas fatigue predicted depression. Careful attention should be paid to cancer patients displaying these significant problems in order to diagnose and treat depression and anxiety disorders of clinical importance.

Prophylactic use of tropisetron or metoclopramide during adjuvant abdominal radiotherapy of seminoma stage I: a randomised, open trial in 23 patients

BACKGROUND AND PURPOSE

Nausea and vomiting are frequent side effects during adjuvant abdominal radiotherapy in seminoma stage I patients. This study evaluates the efficacy and side effects of prophylactically administered tropisetron in comparison to metoclopramide.

MATERIALS AND METHODS

Twenty-three seminoma stage I patients who were to undergo adjuvant abdominal radiotherapy (30 Gy) were included in a prospective, randomised, open study. The patients were allocated to receive adjuvant daily tropisetron 5 mg p.o. (TROP group) (11 patients) or metoclopramide 30 mg p.o. (MET group) (12 patients), allowing an eventual dose increase to 60 mg. Evaluation was based on diary cards filled in by the patients during the treatment period. Nausea, vomiting, abdominal pain and bowel motions were assessed.

RESULTS

Nausea was significantly lower in the TROP group as compared with the MET group (median: 0.14 vs. 1.32; P = 0.03). Thirty percent of all patients experienced vomiting. In the TROP group one patient had a mean number of emetic events > 0 as compared with 6 patients in the MET group (P = 0.07). Two patients in the TROP group and one in the MET group discontinued therapy due to lacking control of emesis. In two further patients the doubling of the metoclopramide resulted in acceptable control of nausea/vomiting. Both drugs were generally well tolerated.

CONCLUSION

Seminoma stage I patients on tropisetron experienced less nausea and vomiting during abdominal radiotherapy than patients receiving metoclopramide. The costs of the former drug may, however, not justify its use as first choice anti-emetic since few patients in either group experienced severe nausea.

Prevalence of anxiety and depression in cancer patients seen at the Norwegian Radium Hospital

The aim of this study was to investigate the prevalence of anxiety and depression in cancer patients seen at the Norwegian Radium Hospital, using the Hospital Anxiety and Depression Scale (HADS), the EORTC QLQ-C33 and an ad hoc designed questionnaire. In addition, information about the patients' malignant disease and treatment was obtained. The prevalence of anxiety and depression among 716 evaluable patients was 13% and 9% respectively, as assessed with HADS. In hospitalised patients, the risk of psychiatric distress was approximately twice that of patients in the outpatient clinic. Female patients reported significantly more anxiety than men. Patients < 30 or > 70 years old expressed less anxiety than all other patients. Age or gender had no influence on the occurrence of depression. Impaired ability to continue professional work and/or daily life activities, impaired social life and previous psychiatric problems were significantly correlated with anxiety and depression as were impaired physical function, fatigue and pain. The prevalence of depression, but not anxiety, increased in the presence of distant metastases, with less than a month since diagnosis, and with relapse or progression. In the logistic regression analysis, a history of previous psychiatric problems and impaired social life were correlated with both anxiety and depression. Female gender, impaired physical activity and impaired social role function were additional predictive parameters for anxiety, whereas fatigue predicted depression. Careful attention should be paid to cancer patients displaying these problems in order to diagnose and treat depression and anxiety disorders.

Radiotherapy after chemotherapy for metastatic seminoma--a diminishing role. MRC Testicular Tumour Working Party

In a retrospective study, data from 302 patients with metastatic testicular seminoma treated with chemotherapy between 1978 and 1990 in 10 European centres were analysed to evaluate the role, if any, of postchemotherapy treatment with irradiation. The primary endpoint of this study was the progression-free survival rate after chemotherapy with or without additional radiotherapy. This was related to the type of primary chemotherapy, sites and sizes of pre- and postchemotherapy masses, the extent of surgical resection after chemotherapy and the use of radiotherapy. 174 patients had residual disease at the end of chemotherapy. The most important prognostic factors for progression were the presence of any visceral metastases or raised LDH prechemotherapy, and the presence of residual disease at visceral sites after chemotherapy. Approximately half the patients with residual masses underwent postchemotherapy radiotherapy, with selection based predominantly on institutional practice. In patients receiving platinum-based chemotherapy, no significant difference was detected in progression-free survival whether or not radiotherapy was employed. Patients receiving BEP (bleomycin, etoposide and cisplatin) had a progression-free survival rate of 88% (95% CI, 80-96%) uninfluenced by postchemotherapy radiotherapy. In patients with residual masses confined to the abdomen after platinum-based chemotherapy, the absolute benefit to radiotherapy was estimated to be 2.3%. The potential benefit of postchemotherapy radiotherapy is minimal, and so it is concluded that the use of adjuvant radiotherapy to residual masses after platinum-based chemotherapy for metastatic seminoma is unnecessary.

[Colonic perforation during combined steroid and radiotherapy. Diagnosis and treatment]

Eight patients with colon perforations after combined treatment with radiotherapy and steroid medication are studied retrospectively. Sigmoid diverticuli perforated after a minimum of 5 days treatment. The main symptom was a varying degree of abdominal pain. Clinical parameters were of limited value. The most important single examination was plain abdominal x-ray, though this was not positive in all cases. Seven patients were operated on, one with simple suture, the rest with Hartmann's procedure. None developed postoperative peritonitis. One died from cerebral infarction. Four died within 38 days postoperatively after discharge from hospital. Abdominal symptoms during high dose steroid treatment may indicate perforation of the colon. Immediate operative intervention may have an uncomplicated postoperative course.

[Press coverage of medical issues]

We assessed the coverage of medical issues in six Norwegian newspapers during the period January - March 1995. A majority of the articles and a minority of the letters presented neutral information about the national health system. 13% of the articles and 61% of the letters were, in our opinion, critical. Only 2% and 5%, respectively, conveyed unequivocally positive attitudes. In at least three out of 11 incidents, the journalists violated the ethical rules commonly accepted by members of the press for criticism of named health workers. In 503 major articles overall correctness of the medical information, as judged by the authors, was 85% and varied between newspapers (top 98%, bottom 70%). We conclude that health workers are more likely to be criticised than praised. The credibility of the medical information varied from one newspaper to another.

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 <pT2 and lowest for pN+ patients (13%). The following independent prognostic parameters were identified for the total group: T category, trial participation, treatment, creatinine, haemoglobin, age and time since initial diagnosis. No significant difference in survival was found when comparing the treatment results obtained before and after 1985. In spite of the introduction of multimodality therapy the treatment results for T2/T3/T4a bladder cancer have remained unchanged. However, subgroups of patients may benefit from this approach allowing bladder conservation in selected cases. More effective adjuvant regimens have to be developed for high-risk patients (pT3b/pN+).

How safe is surveillance in patients with histologically low-risk non-seminomatous testicular cancer in a geographically extended country with limited computerised tomographic resources?

In patients with clinical stage I non-seminomatous testicular cancer only limited information is available about the administrative problems with the surveillance programme, in particular if this policy is to be implemented in a geographically extended country with limited computerised tomography (CT) resources. One hundred and two patients with non-seminomatous testicular cancer clinical stage I and low-risk histology (MRC criteria, UK) were followed by the surveillance policy for at least 1 year after orchiectomy (median 47 months, range 21-81 months). Twenty-two patients (22%) relapsed after a median time of 5 months (range 2-18 months), 14 of them in the retroperitoneal space. Serum alpha-fetoprotein and/or human chorionic gonadotrophin were elevated in eight of the 22 relapsing patients. The progression-free and cancer-corrected survival rates were 78% and 99% respectively. Patient non-compliance did not represent a major problem, whereas the regular and adequate performance of necessary CT examinations yielded some administrative difficulties. One and 3 years after orchiectomy about 50% of the relapse-free patients had no psychological problems and were satisfied with the surveillance programme, whereas 46% reported minor and 4% major psychological distress. Despite non-negligible administrative difficulties in geographically extended countries, surveillance is feasible and safe in compliant patients with low-risk non-seminomatous testicular cancer stage I. The responsible cancer centre and the local hospitals should establish a high degree of cooperation and enable adequate follow-up examinations in these patients.

Aims and results of palliative radiotherapy in urological cancer

Many patients with urological cancer will need palliative treatment during the clinical course of their disease. Although we believe that radiotherapy gives symptom relief in many of these patients, surprisingly few studies have been published that specifically evaluate the symptomatic effects of radiation. Furthermore, optimal fractionation regimens and total doses are uncertain. Future clinical trials should focus on these issues.

Sexuality in patients treated for penile cancer: patients' experience and doctors' judgement

OBJECTIVE

To evaluate sexuality after successful treatment of penile cancer.

PATIENTS AND METHODS

Post-therapy sexuality was evaluated in 30 men (median age 57 years; range 28-75) treated for cancer of the penis 80 months previously (median; range: 11-225 months). Treatment regimes were: local excision/laser beam treatment, 5; definitive radio-therapy, 12; partial penectomy, 9; total penectomy, 4. Patients underwent a semi-structured interview and completed three self-administered questionnaires (psychosocial adjustment to severe illness [PAIS], mental symptoms [GHQ], quality of life [EORTC QLQ C-30]). A global score of overall sexual functioning was constructed consisting of sexual interest, sexual ability, sexual satisfaction, sexual identity, partner relationship and frequency of coitus.

RESULTS

In 10 of 12 patients treated by irradiation the sexual global score was not or only slightly reduced compared with two of nine patients after partial penectomy and one of five patients with local surgery/laser beam treatment. All four patients who had undergone total penectomy recorded a severely reduced sexual global score. Of the six single domains, sexual identity and partner relationship did not change with increasing age, whereas the other scores of sexual life deteriorated as the patient became older. In the patients treated by irradiation doctors evaluated the patients' post-treatment sexuality to be more impaired than that experienced by the patients.

CONCLUSION

Within the limitations due to the small number of patients studied, radiotherapy seems to be the treatment of choice in limited cancer of the penis if preservation of sexuality is a major therapeutic aim. Physicians counselling patients with this rare malignancy need more information about treatment-related problems of sexuality after different therapeutic modalities.

Bladder cancer definitive radiation therapy of muscle-invasive bladder cancer. A retrospective analysis of 317 patients

BACKGROUND

The role of radiation therapy as curative treatment of muscle-invasive bladder cancer was to be analyzed.

METHODS

From 1980-1990, 308 patients with transitional cell carcinoma of the urinary bladder received definitive pelvic radiation therapy (nominal standardized dose greater than or equal to 1700 ret). T categorization was based on clinical examination assessing the palpability of the bladder tumor and its extent (TNM 1978/1982).

RESULTS

The cancer-specific 5-year survival rate for all patients was 24% (crude survival, 20%). The 135 patients with T2/T3a tumors lived significantly longer (5-year survival, 38%) than those with greater than or equal to T3b tumors (5-year survival, 14%). In the former group of patients, age (75 years and younger versus older than 75 years) was significantly correlated with a favorable outcome. The cancer-specific 2-year survival was significantly correlated to clinical response assessed 3-4 months after radiation therapy was 72%, 38%, and 10% in cases of complete response, partial response, and no response/inevaluability, respectively. In a multivariate analysis, the T categorization, patient age, serum creatinine level (less than or equal to 150 mumol/l versus greater than 150 mumol/l), and radiation therapy schedule predicted the 5-year survival rate.

CONCLUSIONS

The clinical T category (< or = T3a versus > or = T3b), based on bimanual palpation, represents an important prognostic parameter, if done by clinicians experienced in onco-urology. High-dose radiation therapy offers a reasonable chance for long-term survival in patients with T2/T3 tumors confined to the bladder wall, especially in patients younger than 76 years. Greater than or equal to 80% of patients with more extended tumors (greater than or equal to T3b) and those older than 75 years of age are not curable by radiation therapy alone. In these patients palliative treatment modalities should be considered, in particular if cisplatin-based chemotherapy is not feasible.

Pre- and post-treatment sexual life in testicular cancer patients: a descriptive investigation

Aspects of sexuality were assessed by questionnaires in 76 testicular cancer patients after orchiectomy before further treatment and, respectively, 6, 12 and 36 months after therapy. Before treatment 11% of the patients reported dissatisfaction with sexual life. About 20% of the patients sometimes experienced reduced libido and erectile difficulties. Six months after therapy significantly more patients (27%) recorded an unsatisfactory sexual life as compared to the pretreatment situation. At the 36 months' evaluation 22 of 76 evaluable patients (18%) still stated that their sexual life was inferior to the pretreatment experience. Libido and erectile function decreased transiently during the first year after treatment in most patients. Twelve patients reported permanent 'dry ejaculation' after bilateral retroperitoneal lymph node dissection. Other sexual disturbances could not be related to specified treatment modalities. Increased age at the time of diagnosis and psychological distress tended to correlate with the incidence of sexual problems. For about 60% of the patients the discussion of expected and experienced sexual life problems was an important issue to be discussed before their treatment for testicular cancer and during follow-up. The high frequency of any kind of long-lasting sexual problems (30%), though often of minor degree, warrants an adequate counselling of these patients before and after treatment.

Asymmetrical autonomic dysfunction of the feet after retroperitoneal surgery in patients with testicular cancer: 2 case reports

We report on 2 patients with hyperhidrosis and decreased temperature of the leg on the unoperated side after unilateral retroperitoneal lymph node dissection. Both patients had a 4 to 5C difference in skin temperature of the feet, with the operated side being warm and dry compared to the nonoperated side. This condition is most likely due to a lesion of sympathetic fibers or ganglia located in close proximity to the retroperitoneal lymph nodes, resembling a unilateral lumbar sympathectomy. In addition, both patients had profuse sweating and a subjective feeling of coldness of the leg on the nonoperated side, which caused considerable discomfort. This latter phenomenon most likely represents a compensatory sympathetic hyperfunction due to the decreased sympathetic function in the other leg.

Acute and subacute side effects due to infra-diaphragmatic radiotherapy for testicular cancer: a prospective study

Acute/subacute side effects were evaluated in 39 testicular cancer patients before infra-diaphragmatic radiotherapy, twice during therapy and 3, 6, and 12 months after treatment discontinuation. The evaluation was primarily based on questionnaires filled in by the patients. At the end of radiotherapy nausea was reported by all responding patients, and 29 patients complained of diarrhea. Two-thirds of the patients reported abdominal pain and/or meteorism, and one-half complained of retching and/or vomiting. During therapy the median weight was significantly reduced by three kilos and the median value of the performance status decreased by 20%. The hematological and biochemical toxicity was low. At the 3-month evaluation more patients complained of nausea, abdominal pain, and meteorism than before irradiation. Compared to the pretreatment situation the patients evaluated their physical condition to be reduced during treatment and at the first follow-up visit. One year posttreatment the patients had regained their physical fitness. All patients in income-producing activity were on sick leave during the period of radiotherapy and for 5 weeks (median) thereafter. In conclusion, infra-diaphragmatic radiotherapy leads to significant but reversible acute/subacute side effects lasting for a median of 9 weeks. It is hoped that better symptomatic therapy and modifications of the radiotherapy technique will reduce the side effects.

Psychosocial well-being in testicular cancer patients

149 testicular cancer patients with no evidence of disease for 3 or more years filled in a questionnaire which covered the following subjects: psychosocial well-being, working ability and use of analgesics/tranquilisers. The questions were chosen to compare cancer patients' morbidity with that of age-matched controls. The patients had been treated with surgery (32 patients), radiotherapy (39 patients), cisplatin-based chemotherapy plus surgery (46 patients) or chemotherapy plus radiotherapy with or without surgery (32 patients). Since no systematic differences between the treatment groups were found, the analyses were undertaken with all patients combined. The patients felt significantly less exhausted after a working day, were more satisfied with life and felt stronger and more fit than the controls. On the other hand, the patients reported a significantly higher incidence of anxiety and depression than the normal population. The results indicate that patients treated for a malignant disease may have greater fluctuations in mood and affect than the general population.

Prediction of long-term gonadal toxicity after standard treatment for testicular cancer

Long-term post-treatment gonadal toxicity was examined (median 3 years after treatment discontinuation) in 125 testicular cancer patients treated with standard regimens: no radiotherapy or chemotherapy (36 patients), infradiaphragmatic radiotherapy (38 patients), and 3-4 cycles of cisplatin-based chemotherapy (51 patients). Radiotherapy and chemotherapy had no impact on serum testosterone, but led to a slight increase in serum follicle-stimulating hormone (FSH). The lowest median value of post-treatment sperm cell count was observed after infradiaphragmatic radiotherapy, the highest value after standard chemotherapy. After more intensive cytotoxic treatment recovery of the gonadal function seemed to be delayed. In testicular cancer long-term post-treatment gonadal toxicity is correlated to the patient's pretreatment gonadal function and age rather than to the standard treatment of the malignancy. In patients with pretreatment normal gonadal function the risk of permanent treatment-induced toxicity is minimal after present standard treatment.

Glomerular filtration rate, 131I-hippuran clearance and estimated creatinine clearance in cancer patients

Glomerular filtration rate (GFR), 131I-Hippuran clearance and estimated creatinine clearance were investigated in 34 patients with cancer. For Hippuran clearance and GFR, analysed with the X-ray contrast (iohexol) and fluorescence technique, the least square linear regression coefficient was 5.01 +/- 0.41 (r = 0.91). This value concurs with the five to one ratio between GFR and renal plasma flow known from normal physiology and supports that Hippuran clearance is a valid measure of renal function. When the individual values of Hippuran clearance were divided by 5.01, the mean difference between the methods was 0.4 ml min-1 1.73 m-2 with standard deviation 13.4 ml min-1 1.73 m-2. The lower and upper limits of agreement were -26.7 and 25.9 ml min-1 1.73 m-2, respectively. Comparing creatinine clearance estimated from the serum creatinine level with GFR, the limits of agreement were -29.4 and 21.6 ml min-1 1.73 m-2. These agreement limits are in the same range as those which can be calculated from the data from other studies.
