The relative risk of second nongerminal malignancies in patients with extragonadal germ cell tumors.

BACKGROUND: Apart from a recognized association between extragonadal mediastinal germ cell tumors (GCT) and the occurrence of hematologic malignancies, the risk of developing second nongerminal solid tumors after the diagnosis or treatment of extragonadal GCT is unknown. METHODS: Six hundred thirty-five consecutive patients with extragonadal GCT treated at 11 centers in the U.S. and Europe during the era of cisplatin-based chemotherapy (1975-1996) were included into a large database. These patients were evaluated for the occurrence of second malignancies. RESULTS: No treatment-related leukemia was observed in 611 patients treated with chemotherapy. In 7 patients, second solid tumors were observed, resulting in a frequency of 1.86% (95% confidence interval [95% CI], 1.79-1.93%) after a median follow-up of 55 months (95% CI, 50-60 months) (annual incidence, 0.30% [95% CI, 0.14-0.59]). Four solid tumors (57%) developed in patients with primary mediastinal and 3 tumors (43%) developed in patients with retroperitoneal GCT. Three patients (43%) had a nonseminomatous and 4 patients (57%) had a seminomatous histology. Six patients had been treated with chemotherapy and one patient with radiotherapy. Six of 7 solid tumors (86%) had developed within 5 years and 7 of 7 solid tumors within 10 years of diagnosis. The median time period to the occurrence of neoplasia was 47 months (range, 9-145 months). Four cutaneous tumors were observed (melanoma, two patients; basal cell carcinoma, one patient; and squamous cell carcinoma, one patient); the other three tumors were angiosarcoma, nonsmall cell lung carcinoma, and colorectal carcinoma. The overall risk for developing a second tumor was not increased compared with an age-matched general population with a standard incidence ratio (SIR) of 1.49 (95% CI, 0.60-3.06). An elevated risk for skin tumors was observed in all extragonadal GCT patients (SIR, 4.00 [95% CI, 1. 09-10.24]), as well as in the subgroup of patients treated with chemotherapy (SIR, 5.33 [95% CI, 1.45-13.65]). CONCLUSIONS: This analysis excludes an increased biologic risk of developing second solid malignancies in patients with extragonadal GCT except for the previously reported association between primary mediastinal nonseminoma and hematologic disorders. The overall risk of developing second malignancies in extragonadal GCT patients appears to be comparable to that in patients with primary testicular carcinoma. The incremental occurrence of skin malignancies in patients treated with chemotherapy should be investigated further.

Hematologic disorders associated with primary mediastinal nonseminomatous germ cell tumors.

BACKGROUND: The association between primary germ cell tumors of the mediastinum (the space between the lung pleura that contains the heart and other chest viscera) and hematologic malignancies has been described by retrospective analysis of patients treated at individual clinical centers. To better characterize the risk of hematologic disorders in patients with extragonadal germ cell tumors and to describe the clinical and biologic features of the disorders, we studied an unselected population in a large, international, multicenter database. METHODS: Six hundred thirty-five patients treated at 11 centers in the United States and Europe from 1975 through 1996 were evaluated retrospectively. RESULTS: A hematologic disorder was observed in 17 patients with germ cell tumors. All cases developed among the 287 patients with primary mediastinal nonseminomatous germ cell tumors, giving an incidence rate in this group of 2.0% (95% confidence interval [CI] = 1.1%-3.1%) per year over a median follow-up time of 3 years. The risk of developing hematologic disorders was statistically significantly increased in patients with primary mediastinal nonseminomatous germ cell tumors in comparison with the age-matched general population (standardized incidence ratio = 250; 95% CI = 140-405). The median time to onset of hematologic neoplasia was 6 months (range, 0-47 months), and the median survival after diagnosis of the hematologic disorder was 5 months (range, 0-16 months) (two-sided P<.0001, comparing survival from the time of diagnosis of the germ cell tumor of patients with and without hematologic disorders). CONCLUSION: In our study, approximately one in 17 patients with primary mediastinal nonseminomatous germ cell tumors was affected by a hematologic disorder, whereas no cases were seen among 334 patients with other extragonadal germ cell tumors. The hematologic disorder had a statistically significant impact on prognosis, with none of the 17 reported patients surviving for more than 2 years.

Abdominal relapse in stage 1 nonseminomatous germ cell tumours of the testis managed by surveillance or with adjuvant chemotherapy.

OBJECTIVE: To assess the impact on patterns of recurrence of adjuvant chemotherapy in patients with stage 1 nonseminomatous germ cell tumours (NSGCT) of the testis, who have a high likelihood of relapse on surveillance if certain risk factors are identified in the orchidectomy specimen, and thus the theoretical need for retroperitoneal lymph node dissection (RPLND). PATIENTS AND METHODS: The incidence of abdominal relapse was recorded in 417 men presenting with stage 1 NSGCT over the past 18 years. Up to 1986, 161 men were managed by surveillance alone, and abdominal relapse occurred in 26. From 1986 onwards, men with positive risk factors in the orchidectomy specimen were offered two courses of chemotherapy; 60 accepted and one relapsed in the abdomen, and 196 underwent surveillance and 19 relapsed in the abdomen. RESULTS: Abdominal relapse was significantly reduced from 16% before 1986 to 8% afterward (P = 0.014). Mortality from testicular tumour or treatment toxicity remained low, at 0.6% before 1986 and 2.0% since then. CONCLUSION: The need for RPLND in stage 1 NSGCT remains highly doubtful.

The utility of tumour markers in assessing the response to chemotherapy in advanced bladder cancer.

In patients with advanced bladder cancer receiving chemotherapy, early assessment of response can avoid unnecessary toxicity. The aim of this study was to assess the role of tumour markers in monitoring response. Serum levels of one or more of markers beta human chorionic gonadotrophin (betahCG), carcinoembryomic antigen (CEA), CA125 and CA19.9 were measured in 74 patients with advanced bladder cancer receiving chemotherapy from 1992 to 1997. Forty-three of 74 (58%) of patients had at least one raised marker (1.5 times upper limit of normal range). This was more common in patients with extra-pelvic disease than in those with disease confined to the pelvis (P = 0.002). Thirty-eight of 78 (49%) assessable patients had a radiological response. Neither clinical response (P = 0.81) nor survival (P = 0.16) differed between marker-negative and marker-positive patients. Clinical response was strongly related to marker response in the 35 comparable patients (P = 0.0001). No patient had a clinical response without response of at least one marker. Ninety per cent of patients who achieved a marker response had done so by 8 weeks. Monitoring of tumour markers in patients with advanced bladder cancer can help predict the response to chemotherapy.

A medical research council randomized trial of single agent carboplatin versus etoposide and cisplatin for advanced metastatic seminoma. MRC Testicular Tumour Working Party.

The UK Medical Research Council conducted this trial of carboplatin chemotherapy in advanced seminoma to compare single agent carboplatin with a standard combination of etoposide with cisplatin. The use of single agent carboplatin was expected to be associated with reduced toxicity. A total of 130 patients with advanced seminoma were randomly assigned to treatment with either single agent carboplatin (C) at a dose of 400 mg/m(2)to be corrected for glomerular filtration rate outside the range 81-120 ml min(-1)and to be administered on day 1 of a 21 day cycle to a total of 4 cycles or to etoposide + platinum (EP). The trial was designed as an equivalence study aiming to exclude a reduction in the 3-year progression-free survival in patients allocated to carboplatin of between 10 and 15%, requiring initially a target accrual of 250 patients (90% power significance level 5% (one-sided)). The trial closed after 130 patients had been randomized following recommendation by an independent data monitoring committee. At a median follow-up time of 4.5 years, 81% of patients had been followed up for at least 3 years and 19 patients have died. The estimated PFS rate (95% Confidence Intervals (CI)) at 3 years was 71% (60-82%) in patients allocated C and 81% (71-90%) in those allocated EP; the 95% CI for the difference in 3 year PFS was - 6% to +19%. The hazard ratio of 0.64 (95% CI 0.32-1.28) favoured EP but the difference was not statistically significant (log rank chi-squared = 1.59 P = 0.21). The 3-year survival rate was 84% (75-92%) in those allocated C, and 89% (81-96%) in those allocated EP. The hazard ratio for survival was 0.85 with 95% CI, 0.35-2.10, log rank chi-squared = 0.12, P = 0.73. The trial has not demonstrated statistically significant differences in the major survival endpoints comparing single agent carboplatin with a combination of etoposide + cisplatin. This cannot be taken as an indication of equivalence since the limited size of this trial rendered it unable to exclude a 19% lower progression-free survival and survival in those treated with single agent carboplatin which would be important clinically. Standard initial chemotherapy for advanced seminoma should be based on cisplatin combinations and the role of carboplatin awaits the outcome of further studies.

Risk of second malignancy after Hodgkin's disease in a collaborative British cohort: the relation to age at treatment.

PURPOSE: To assess long-term site-specific risks of second malignancy after Hodgkin's disease in relation to age at treatment and other factors. PATIENTS AND METHODS: A cohort of 5,519 British patients with Hodgkin's disease treated during 1963 through 1993 was assembled and followed-up for second malignancy and mortality. Follow-up was 97% complete. RESULTS: Three hundred twenty-two second malignancies occurred. Relative risks of gastrointestinal, lung, breast, and bone and soft tissue cancers, and of leukemia, increased significantly with younger age at first treatment. Absolute excess risks and cumulative risks of solid cancers and leukemia, however, were greater at older ages than at younger ages. Gastrointestinal cancer risk was greatest after mixed-modality treatment (relative risk [RR] = 3.3; 95% confidence interval [CI], 2.1 to 4.8); lung cancer risks were significantly increased after chemotherapy (RR = 3. 3; 95% CI, 2.4 to 4.7), mixed-modality treatment (RR = 4.3; 95% CI, 2.9 to 6.2), and radiotherapy (RR = 2.9; 95% CI, 1.9 to 4.1); breast cancer risk was increased only after radiotherapy without chemotherapy (RR = 2.5; 95% CI, 1.4 to 4.0); and leukemia risk was significantly increased after chemotherapy (RR = 31.6; 95% CI, 19.7 to 47.6) and mixed-modality treatment (RR = 38.1; 95% CI, 24.6 to 55. 9). These risks were generally greater after treatment at younger ages: for patients treated at ages younger than 25 years, there were RRs of 18.7 (95% CI, 5.8 to 43.5) for gastrointestinal cancer after mixed-modality treatment, 14.4 (95% CI, 5.7 to 29.3) for breast cancer after radiotherapy, and 85.2 (95% CI, 45.3 to 145.7) for leukemia after chemotherapy (with or without radiotherapy). CONCLUSION: Age at treatment has a major effect on risk of second malignancy after Hodgkin's disease. Although absolute excess risks are greater for older patients, RRs of several important malignancies are much greater for patients who are treated when young. The increased risk of gastrointestinal cancers may relate particularly to mixed-modality treatment, and that of lung cancer to chemotherapy as well as radiotherapy; there are also well-known increased risks of breast cancer from radiotherapy and leukemia from chemotherapy. The roles of specific chemotherapeutic agents in the etiology of solid cancers after Hodgkin's disease require detailed investigation.

Treatment of nondysgerminomatous ovarian germ cell tumors: an analysis of 69 cases.

BACKGROUND: Combination chemotherapy has dramatically improved the prognosis of patients with nondysgerminomatous ovarian germ cell tumors (NDOGCT). However, guidelines are needed for the identification of patients at risk of relapse. METHODS: The authors performed a retrospective analysis of women with NDOGCT managed during the period 1970-1994 at the Royal Marsden Hospital and other hospitals of the London Gynaecological Oncology Group. RESULTS: Sixty-nine women were included; their median follow-up was 5.7 years (minimum, 12 months). The median age was 21 years (range, 4-44 years), with a histology of immature teratoma (IT) for 17 patients, endodermal sinus tumor (EST) for 20 patients, and mixed tumors for 32 patients. Thirty-five patients (51%) had Stage I disease. Nine patients with Stage I tumors were observed without further therapy (six with IT and three with mixed tumors), and one relapsed. Seven patients received non-platinum-based chemotherapy, and four relapsed. A total of 52 patients were treated with platinum-based chemotherapy, with relapse free and overall survival rates of 87% (95% confidence interval [CI], 73-93%) and 84% (95% CI, 70-91%), respectively. Of these patients, relapse was seen in 0 of 9 IT patients, 1 of 25 patients with mixed tumors, and 6 of 18 EST patients. With alpha-fetoprotein (AFP) > 1000 kU/L, relapse was seen in 6 of 18 patients compared with 1 of 33 relapses with lower AFP levels. In multivariate analysis, including all patients who received chemotherapy, AFP >1000 kU/L (P = 0.001) and non-platinum-based chemotherapy (P = 0.005) were associated with relapse. When only patients given platinum-based treatment were considered, EST histology (P = 0.003) and AFP >1000 kU/L (P = 0.003) were associated with relapse in univariate analysis; however, these factors were linked. No malignant tumor was found at second-look surgery performed on 24 patients. Of 26 women assessable for fertility, 24 subsequently recommenced regular menstrual function, and 11 patients had pregnancies. CONCLUSIONS: Platinum-based chemotherapy has been confirmed to be effective in the management of patients with NDOGCT. Relapses were principally seen among patients with AFP >1000 kU/L or pure EST histology. Efforts to improve outcome need to focus on patients with EST, whereas less intensive management strategies may be appropriate for some patients with IT.

Comparison of radiation side-effects of conformal and conventional radiotherapy in prostate cancer: a randomised trial.

BACKGROUND: Radical radiotherapy is commonly used to treat localised prostate cancer. Late chronic side-effects limit the dose that can be given, and may be linked to the volume of normal tissues irradiated. Conformal radiotherapy allows a smaller amount of rectum and bladder to be treated, by shaping the high-dose volume to the prostate. We assessed the ability of this new technology to lessen the risk of radiation-related effects in a randomised controlled trial of conformal versus conventional radiotherapy. METHODS: We recruited men with prostate cancer for treatment with a standard dose of 64 Gy in daily 2 Gy fractions. The men were randomly assigned conformal or conventional radiotherapy treatment. The primary endpoint was the development of late radiation complications (> 3 months after treatment) measured with the Radiation Therapy and Oncology Group (RTOG) score. Indicators of disease (cancer) control were also recorded. FINDINGS: In the 225 men treated, significantly fewer men developed radiation-induced proctitis and bleeding in the conformal group than in the conventional group (37 vs 56% > or = RTOG grade 1, p=0.004; 5 vs 15% > or = RTOG grade 2, p=0.01). There were no differences between groups in bladder function after treatment (53 vs 59% > or = grade 1, p=0.34; 20 vs 23% > or = grade 2, p=0.61). After median follow-up of 3.6 years there was no significant difference between groups in local tumour control (conformal 78% [95% CI 66-86], conventional 83% [69-90]). INTERPRETATION: Conformal techniques significantly lowered the risk of late radiation-induced proctitis after radiotherapy for prostate cancer. Widespread introduction of these radiotherapy treatment methods is appropriate. Our results are the basis for dose-escalation studies to improve local tumour control.

Preliminary results of a phase I dose escalation clinical trial using focused ultrasound in the treatment of localised tumours.

OBJECTIVE: The primary aim of this phase I trial was to assess the tolerance of cancer patients to focused ultrasound (FUS) treatment in a variety of different sites and to document any associated acute or delayed toxicity. This would appear to be the first time that treatment has been given without sedation or anaesthesia. METHODS: Patients with advanced and/or metastatic disease were eligible for entry into this study. Previous work has established that an in situ ablative intensity (AI) of 1500 W/cm2 Isp for 1 s achieves coagulative necrosis at the focal spot. Ultrasonic exposures of 25-100% of AI for 1 s were delivered to preselected tissue volumes. Pain questionnaires recording any side effects were completed by the patient and the investigator separately. Ultrasound images of the target volume were taken before, immediately after, and 1 week after treatment. RESULTS: A total of 14 patients have been entered into this study to date. Seven patients were treated at their primary site and seven received treatment to one of their metastases. No treatment needed to be stopped because of pain. Eight of the 14 patients did not complain of any side effect during or after the treatment. One patient complained of mild, and two of moderate pain during the week following treatment. One patient developed an asymptomatic blister on the skin. CONCLUSION: Focused ultrasound is a safe, well-tolerated and non-invasive method of delivering ablative thermal energy to selected tumours. More clinical trials are needed to assess the role of this modality in the treatment of cancer.

Prognostic factors in patients progressing after cisplatin-based chemotherapy for malignant non-seminomatous germ cell tumours.

The aim of this study was to define prognostic parameters for survival in patients with malignant germ cell tumours progressing after platinum-based induction chemotherapy with or without surgery. A total of 164 progressing patients (testicular: 83%, extragonadal: 17%) were identified out of 795 patients treated with platinum-based induction chemotherapy for metastatic germ cell malignancy with or without surgery. 'Progressive disease' included patients who had progressed after a previous partial or complete remission as well as patients who failed primary therapy. Salvage chemotherapy consisted of 'conventional' platinum-based chemotherapy. Prognostic factors for survival were assessed by uni- and multivariate analyses. The resulting prognostic model was validated in an independent data set of 66 similar patients. For all 164 patients the median time from start of induction chemotherapy to progression was 10 months (range: 0-99). Thirty-eight (23%) patients relapsed after 2 years. The 5-year survival rate for all progressing patients was 30% (95% confidence interval 23-38%). In the univariate analysis the following factors most importantly predicted a poor prognosis: progression-free interval < 2 years: initial poor prognosis category (MRC criteria), < CR to induction chemotherapy, initial treatment early in the 1980s and treatment given at a 'small' centre. Three prognostic factors remained in the multivariate analysis: progression-free interval, response to induction treatment and the level of serum human chronic gonadotrophin (hCG) and alpha fetoprotein (AFP) at relapse. One hundred and twenty-four patients could be classified on the basis of these characteristics, Those patients with progression-free interval < 2 years, < CR to induction chemotherapy and high markers at relapse (AFP >100 kU l(-1) or hCG >100 IU l(-1)) formed a poor prognosis group of 30 patients, none of whom survived after 3 years. Patients with at most two of these three risk factors formed a good prognosis group of 94 patients (76%) with a 47% (37-56%) 5-year survival. Thirty-eight patients from the good prognosis group with a progression-free interval of >2 years had a 2-year survival of 74% (60-88%) and 5-year survival of 61%. These prognostic groups were validated in the independent data set, in which 5-year survival rates in the good and poor risk groups were 51% and 0% respectively. One-third of patients progressing during or after platinum-based induction chemotherapy for metastatic germ cell malignancy may be cured by repeated 'conventional' platinum-based chemotherapy. Good prognosis parameters are: progression-free interval of > 2 years, CR to induction treatment and normal or low serum markers at relapse (hCG < 100 IU l(-1) and AFP < 100 kU l(-1)). The results of high-dose salvage chemotherapy should be interpreted on the background of these prognostic factors.

Hypofractionated radiotherapy for patients with carcinoma of the bladder.

In order to develop a low toxicity regimen of bladder radiotherapy for the palliation of patients with poor performance status we carried out a Phase II study of weekly 6 Gy fractions to a maximum dose of 30-36 Gy in 65 patients with T(2)-T(4) bladder cancer (median age 81 years). A complete response was obtained in 23/37 (62%) assessable patients at cystoscopy. Local control was achieved in 16/65 (25%) patients. The median survival of all 65 patients was 35 weeks, and the 2-year actuarial survival 21%. The main acute toxicity was urinary frequency as often as hourly at the peak of the reaction (Radiation Therapy Oncology Group (RTOG) grade 3) in seven patients, and urinary obstruction (RTOG grade 4) in one. The reactions may have been compounded by the effects of locally advanced tumour. Late bladder toxicity amongst the 16 patients who were evaluable after 1 year included four patients with persisting frequency, one with severe haematuria (RTOG grade), and one with a bladder capacity <100 ml (RTOG grade 4). One patient experienced RTOG grade 4 late bowel and bladder morbidity. Weekly 6 Gy fractions to a total dose of 30-36 Gy is a satisfactory palliative regimen for patients with advanced bladder cancer who cannot tolerate standard radical radiotherapy, but it may produce significant late bladder morbidity.

Optimal planning target volume for stage I testicular seminoma: A Medical Research Council randomized trial. Medical Research Council Testicular Tumor Working Group.

PURPOSE: To compare relapse rates and toxicity associated with para-aortic (PA) strip or PA and ipsilateral iliac lymph node irradiation (dogleg [DL] field) (30 Gy/15 fractions/3 weeks) for stage I testicular seminoma. PATIENTS AND METHODS: Between July 1989 and May 1993, 478 men with testicular seminoma stage I (T1 to T3; no ipsilateral inguinoscrotal operation before orchiectomy) were randomized (PA, 236 patients; DL, 242 patients). RESULTS: Median follow-up time is 4.5 years. Eighteen relapses, nine in each treatment group, have occurred 4 to 35 months after radiotherapy; among these, four were pelvic relapses, all occurring after PA radiotherapy. However, the 95% confidence interval (CI) for the difference in pelvic relapse rates excludes differences of more than 4%. The 3-year relapse-free survival was 96% (95% CI, 94% to 99%) after PA radiotherapy and 96.6% (95% CI, 94% to 99%) after DL (difference, 0.6%; 95% confidence limits, -3.4%, +4.6%). One patient (PA field) has died from seminoma. Survival at 3 years was 99.3% for PA and 100% for DL radiotherapy. Acute toxicity (nausea, vomiting, leukopenia) was less frequent and less pronounced in patients in the PA arm. Within the first 18 months of follow-up, the sperm counts were significantly higher after PA than after DL irradiation. CONCLUSION: In patients with testicular seminoma stage I (T1 to T3) and with undisturbed lymphatic drainage, adjuvant radiotherapy confined to the PA lymph nodes is associated with reduced hematologic, gastrointestinal, and gonadal toxicity, but with a higher risk of pelvic recurrence, compared with DL radiotherapy. The recurrence rate is low with either treatment. PA radiotherapy is recommended as standard treatment in these patients.

Postchemotherapy residual masses in germ cell tumor patients: content, clinical features, and prognosis. Medical Research Council Testicular Tumour Working Party.

BACKGROUND: In a retrospective study that included a detailed histopathologic review, the clinicopathologic features of patients with germ cell tumors (GCT) and resectable residual masses after chemotherapy were assessed. METHODS: Histologic material from 153 patients was available for review. Recorded details included primary histologic diagnosis, location, size and number of metastases, marker levels before and after chemotherapy, and completeness of surgical excision. A median of seven histologic sections per resection were reviewed by two pathologists independently (and together when disagreement occurred). In each case, details were recorded regarding fibrosis, necrosis, hemorrhage, embryonal carcinoma (undifferentiated teratoma), yolk sac tumor, choriocarcinoma (trophoblastic tumor), differentiated teratoma (mature and immature), dysplasia in somatic tissues, and non- germ cell tumor (GCT) malignancies. The percentage of the sample that each of these components comprised was also estimated. RESULTS: The median postchemotherapy follow-up time was 7 years, and 38 of 153 patients (25%) experienced disease progression. In a multivariate analysis, incomplete resection of all residual masses (in 38 patients) and the presence of malignant elements (in 23 patients) were independent risk factors for progression. In the subset of patients in whom all masses were completely resected, the presence of embryonal carcinoma (undifferentiated teratoma) was the single most significant risk factor for progression. Seven percent of patients had this factor, which was associated with a 2-year progression free survival rate of 12.5%, compared with 88.0% where this component was absent. CONCLUSIONS: Progression free survival can be predicted well by the completeness of excision of residual masses and the presence of malignant germ cell elements. The latter confers a relatively poor prognosis even if all of these elements are completely resected.

Evaluation of adjuvant psychological therapy in patients with testicular cancer: randomised controlled trial.

OBJECTIVE: To determine the efficacy of adjuvant psychological therapy in patients with testicular cancer and to compare the characteristics and psychosocial outcomes of men who agreed to participate with those who declined to participate in a randomised trial of psychological intervention. DESIGN: Newly diagnosed patients were asked to participate in a randomised trial of psychological support compared with standard medical care. Participants and non-participants completed self assessment questionnaires at baseline and at 2, 4 and 12 months. SETTING: Testicular Tumour Unit of the Royal Marsden Hospital. SUBJECTS: 73 of 184 (40%) eligible patients agreed to enter the randomised trial (participants) and 81 (44%) declined to participate but agreed to complete further assessments (non-participants). 30 patients wanted no further contact with the researchers. OUTCOME MEASURES: Hospital anxiety and depression scale, psychosocial adjustment to illness scale, Rotterdam symptom checklist, mental adjustment to cancer scale. Only scores on the hospital anxiety and depression scale are reported for evaluating treatment efficacy. RESULTS: 111 of 184 (60%) eligible men declined to participate in the trial. Patients with stage I disease were most likely to refuse to participate. A patient was less likely to participate if he had low volume disease and was receiving no further treatment. Likelihood of participation was associated with stage of disease and with type of primary treatment (P < 0.001 for heterogeneity). Patients with early stage disease (P < 0.001) and fewer physical symptoms (P < 0.001) were less likely to participate. Psychosocial factors associated with participation included anxious preoccupation regarding disease (P = 0.01). There were no differences in outcome between participants and non-participants during follow up. Patients seemed to gain little benefit from adjuvant psychological therapy. At 2 months change from baseline favoured the treated group in the anxiety subscale (mean difference between groups -1.41 (95% confidence interval -2.86 to 0.03)). This was not sustained when adjusted for factors related to the disease. By 12 months change from baseline seemed to favour the control group (mean difference between groups 1.66 (-0.18 to 3.50)). CONCLUSIONS: Patients with testicular cancer seem to have considerable coping abilities. Those who declined to participate in the trial differed from those who participated. Those who agreed to participate may comprise the clinical group who perceive a need for psychological support. No evidence was found to indicate a need for routinely offering adjuvant psychological therapy.

Thoracic metastasectomy for germ cell tumours: long term survival and prognostic factors.

BACKGROUND: This study evaluated the results of thoracic metastasectomy for germ cell tumours to assess long term survival and identify prognostic factors. PATIENTS AND METHODS: A series of 141 consecutive patients who underwent resection of thoracic metastases at Royal Brompton Hospital were retrospectively reviewed. Kaplan-Meier estimates of survival were calculated for clinical variables related to primary tumour and thoracic metastases, using the Cox model for multivariate analysis. RESULTS: Complete resection was achieved in 123 cases (87%); pathology showed viable malignant elements in 46 (32%), necrosis or fibrosis in 32, differentiated teratoma in 63. The overall survival was 77% at five years and 65% at 15 years, being significantly shorter in patients with malignant teratomatous elements (51% at five years, P = 0.0001) or incomplete resection (64% at five years, P = 0.019). At multivariate analysis these factors retained their prognostic value, with a relative risk of death of 5.7 for malignant teratomatous elements and 4.0 for incomplete resection. In addition, the Cox model revealed a 3.2 times higher risk of relapse in patients with malignant teratomatuos elements at the time of thoracic metastasectomy. CONCLUSIONS: These data confirm the value of thoracic metastasectomy to asses pathological response and achieve permanent cure of chemoresistant disease.
