RESUMO

BACKGROUND: High cure rates are expected in good-risk metastatic nonseminomatous germ-cell tumor (NSGCT) patients with bleomycin, etoposide and cisplatin. PATIENTS AND METHODS: Patients received either three cycles of BE500P or four cycles of E500P every 3 weeks. Disease was defined according to the Institut Gustave Roussy prognostic model. Patients were retrospectively assigned into the International Germ Cell Cancer Collaborative Group (IGCCCG) classification. A sample size of 250 patients was necessary for an expected favorable response rate (primary end point) of 90% and not more than a 10% difference between the two arms. RESULTS: Among 257 assessable patients, 124 and 122 patients achieved a favorable response in the 3BE500P and 4E500P arms, respectively (P = 0.34). Median follow-up was 53 months. The 4-year event-free survival rates were 91% and 86%, respectively (P = 0.135). The 4-year overall survival rates were not significantly different [five deaths versus 12 deaths, respectively (P = 0.096)]. Similar nonsignificant trends were observed in good IGCCCG prognosis patients. CONCLUSIONS: Both regimens produced similar results in terms of favorable response rates. As the trial was underpowered for survival analyses, conclusive data would require a larger randomized trial. Unless such a study is done, 3BE500P is the treatment of choice for metastatic NSGCT patients.

RESUMO

BACKGROUND: High-dose chemotherapy (HD-CT) is able to circumvent platinum resistance of resistant/refractory germ-cell tumors (GCTs), but expectancy of cure remains low. New strategies are needed with new drugs and a sequential approach. MATERIALS AND METHODS: Patients with relapsed poor-prognosis GCTs were scheduled to receive two cycles combining epirubicin and paclitaxel (Taxol) followed by three consecutive HD-CT supported by stem cell transplantation [one course combining cyclophosphamide, 3 g/m(2) + thiotepa, 400 mg/m(2), followed by two ICE regimens (ifosfamide, 10 g/m(2), carboplatin, AUC 20, etoposide, 1500 mg/m(2))]. RESULTS: From March 1998 to September 2001 (median follow-up, 31.8 months), 45 patients (median age, 28 years) were enrolled in this phase II study. Twenty-two patients received the complete course. Twenty-five patients died from progression and five from toxicity. The overall response rate was 37.7%, including an 8.9% complete response rate. The median overall survival was 11.8 months. The 3-year survival and progression-free survival rate was 23.5%. The 'Beyer' prognostic score predicted the outcome after HD-CT. CONCLUSION: Although our results warrant further studies on HD-CT in relapsed poor prognosis GCTs, patients with a Beyer score >2 did not benefit from this approach and should not be enrolled in HD-CT trials. Better selection criteria have to be fulfilled in forthcoming studies.

RESUMO

PURPOSE: To evaluate quality of life and social problems in long-term survivors of testicular cancer. PATIENTS AND METHODS: In 1998, 71 testicular cancer survivors (cases) identified from the Calvados General Tumor Registry were enrolled onto a case-control study. One hundred nineteen healthy control subjects (controls), matched by age and location of residence, were selected at random from electoral rolls. Three self-administered questionnaires were used: two health-related quality-of-life questionnaires (Short Form-36 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 core questionnaires) and one life situation questionnaire. Specific questions concerning sexuality were also added. RESULTS: With a mean follow-up of 11 years, health-related quality-of-life scores did not differ significantly between cases and controls, nor did general symptom scores. Psychosocial problems were reported equally by cases and controls. Cases reported more modification of sexual life (P =.04) with decreased sexual enjoyment (P <.01), decreased desire (P =.02), and infertility (P <.01). Cases did not report more divorce than controls; they reported fewer changes in relationships with friends (P =.03). Although a similar proportion of cases and controls were at work, cases expressed less ambitious professional plans (P =.002). Cases had greater difficulty in borrowing from banks (P <.001). CONCLUSION: French long-term survivors of testicular cancer do not express more impairment of health-related quality of life or familial or professional life in comparison with healthy men. They did have more sexual life problems and found difficulty in borrowing from banks. This information should be used by practitioners to help their patients cope with their disease and return to normal life.

RESUMO

The main risk factors of infectious complications in cancer patients result from immune deficiency more or less related to cancer. Prognosis is related to the type and grade of the underlying disease. Prospective studies should be conducted to update data on the frequency of infections, morbidity and mortality (expert agreement). Prospective studies are needed to follow the epidemiology in cancer patients, particularly in neutropenic patients (expert agreement). Prospective studies should be conducted to determine prognosis factors allowing precise recognition of "low-risk" neutropenic patients with fever who could benefit from home care (expert agreement). When infection is suspected, the first criterion determining the therapeutic attitude concern signs of gravity requiring emergency care (septic shock). Beyond this situation, the first criterion determining the therapeutic attitude is the severity of the neutropenia. Microbial diagnosis is essential for initiating and later adapting anti-infectious treatment as well as for assessing efficacy.

RESUMO

PURPOSE: To evaluate late physical and psychosocial sequelae in patients treated with an association of external beam irradiation (EBI) and brachytherapy (BT) for localized prostate cancer. PATIENTS AND METHODS: Seventy-one patients free of disease, treated at the Centre François Baclesse from 1988 to 1992, were enrolled in a case-control study. Seventy-one healthy controls, matched on age and residence, were selected at random from electoral rolls. Two self-administered questionnaires were mailed in January 1996. The French translation of the Nottingham Health Profile questionnaire and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 core questionnaire were used to evaluate physical, role, emotional, cognitive and social functioning, global health status as well as energy and sleep disturbance. Specific problems related to prostate cancer were explored using the prostate specific module developed by the EORTC Genito-Urinary Tract Cancer Cooperative Group. Concordance between clinical complications reported by patients and those reported by physicians was also analyzed. RESULTS: General health quality of life scale scores did not significantly differ between patients and controls, nor did general symptom scale scores. Furthermore, no more late psychosocial sequelae were reported by patients than by controls. No major digestive complications were observed among patients. However, statistical differences were observed concerning interest in sex (P = 0.016) and sexual activity (P < 0.001), urinary incontinence (P < 0.001) and cystitis (P = 0.01). Late subjective morbidity (dysuria, nocturia, urinary incontinence, pelvic pain) appraisal differed slightly between patients and physicians who generally underestimate its severity. While nocturia was reported more often by physicians than by patients (P = 0.0016), patients reported urinary incontinence and pelvic pain more often than physicians (P < 0.001 and P < 0.001, respectively). CONCLUSIONS: The study demonstrates that survivors from localized prostate cancer treated with an association of BT and EBI have good global health status. Major problems that persist are sexual disorders, urinary incontinence and cystitis while digestive disorders were rare. This association could be an alternative to standard EBI in patients with localized prostate cancer. Whatever the treatment choice, patients should be involved in the therapeutic decision which should consider not only expected survival rate but also quality of life.

RESUMO

BACKGROUND: Recombinant human interleukin-2 (aldesleukin) and recombinant human interferon alfa can induce notable tumor regression in a limited number of patients with metastatic renal-cell carcinoma. We conducted a multicenter, randomized trial to determine the effect of each cytokine independently and in combination, and to identify patients who are best suited for this treatment. METHODS: Four hundred twenty-five patients with metastatic renal-cell carcinoma were randomly assigned to receive either a continuous intravenous infusion of interleukin-2, subcutaneous injections of interferon alfa-2a, or both. The main outcome measure was the response rate; secondary outcomes were the rates of event-free and overall survival. Predictive factors for response and rapid progression were identified by multivariate analysis. RESULTS: Response rates were 6.5 percent, 7.5 percent, and 18.6 percent (P<0.01) for the groups receiving interleukin-2, interferon alfa-2a, and interleukin-2 plus interferon alfa-2a, respectively. At one year, the event-free survival rates were 15 percent, 12 percent, and 20 percent, respectively (P=0.01). There was no significant difference in overall survival among the three groups. Toxic effects of therapy were more common in patients receiving interleukin-2 than in those receiving interferon alfa-2a. Response to treatment was associated with having metastasis to a single organ and with receiving the combined treatment. The probability of rapid progression of disease was at least 70 percent for patients with at least two metastatic sites, liver metastases, and a period of less than one year between the diagnosis of the primary tumor and the appearance of metastases. CONCLUSIONS: Cytokines are active in a few patients with metastatic renal-cell carcinoma. The higher response rate and longer event-free survival obtained with a combination of cytokines must be balanced against the toxicity of such treatment.

RESUMO

One case of neuroblastoma arising in an adult immature testicular teratoma is described, with multiple systemic metastases, a partial response to intensive chemotherapy and a swift recurrence leading to death. Such instances of prevailing neuroblastoma with systemic metastases, have only seldomly been reported hitherto. Because of the teratoma and the focal presence of intratubular germ cell neoplasia of unclassified type, we think this tumor must be indeed of germ cell derivation.

RESUMO

Verrucous carcinoma (VC) of the skin is a rare variety of well-differentiated squamous cell carcinoma (SCC) characterized by aggressive local growth and a low metastatic potential. These tumours are known to have histological and virological features similar to classic warts or condylomata. The aim of the present study was to map the proliferative compartment in VC (n = 7) in comparison with warts (n = 10) and typical well-differentiated SCC (n = 10). The proliferating cells were detected by immunostaining of proliferating cell nuclear antigen (PCNA) in formalin-fixed, paraffin-embedded tissue sections, using the commercially available anti-PCNA monoclonal antibody PC10. Normal epidermis served as a positive control and reference. In VC and warts, the PCNA-positive cells were principally located at the periphery of lesions, in the basal layer of the tumour islands. In some warts, however, stronger PCNA expressed was noted in the superficial layers, of the lesions corresponding to virus-infected keratinocytes (koilocytotic cells). In contrast, in SCC, PCNA-positive cells were randomly scattered throughout the tumours. Our findings suggest that, on the basis of mapping of PCNA distribution, VC resembles large warts or condylomata rather than typical SCC. Thus, VC appears to be a distinct clinical entity, intermediate between these two types of lesions, not only because of its clinical entity, intermediate between these two types of lesions, not only because of its clinical and virological features, but also with regard to its proliferative organization.

RESUMO

Prostate specific antigen (PSA) is a prostate tissue marker detected by immunostaining in 97% of specimens examined. Tissue staining is variable and cancers are more heterogeneous than normal or hyperplastic prostate. Serum PSA levels in patients with normal or hyperplastic lesions are 12 ng/ml + 19 and are positively correlated with the weight of the gland. In patients with carcinoma serum PSA levels are 216 ng/ml + 782 and are positively correlated with tumor spread. PSA assay is of little value for screening for prostatic carcinoma. However, carcinoma of prostate is more frequent when PSA levels are above 10 ng/ml and the level of 50 ng/ml indicates capsular penetration, seminal vesicle or lymph node involvement or metastatic spread.

RESUMO

9-hydroxy-2-methyl-ellipticinium (HME) is an intercaling agent mainly potent in metastatic breast cancer. Its almost complete lack of bone marrow toxicity is of greatest value. However, among 385 patients 20 cases of renal failure were observed: renal failure is gradual, non reversible except in four cases with acute renal failure. Histological and ultrastructural studies, performed in 8 cases, showed exclusively proximal tubular lesions, without glomerular or interstitial lesions. We have evidence that there is a relation between the cumulative dose and the severity of the lesions. A prospective study was done in 30 patients. An increase in enzymuria, proteinuria and glycosuria was observed in most patients after HME infusion. HME is an efficient drug in the treatment of bone metastases of breast cancer. Renal function should be carefully monitored during HME administration.
