RESUMO

BACKGROUND: This study presents the results of an extended phase II study originally published in 2007, regarding the antitumor activity and toxicity of a non-platinum containing regimen with paclitaxel and capecitabine for the treatment of recurrent or disseminated squamous cell carcinoma of the head and neck region. Fifty patients were included in the original study. MATERIALS AND METHODS: A total of 183 patients with recurrent or disseminated squamous cell carcinoma were eventually included in the extended study. There were 37 women and 146 men. The mean age was 56 years. Performance status (WHO) was as follows: WHO 0:31, WHO 1:107, and WHO 2:45 patients. The treatment consisted of paclitaxel 175 mg/m2, once every third week and capecitabine 825 mg/m2 p.o. b.i.d for 2 weeks. RESULTS: The overall response rate (complete response and partial response) according to the WHO criteria was: 33% (CI 26-40). The median progression-free survival was 4.8 (CI 4.2-5.4) months. The median overall survival (OS) was 8.9 (CI 7.6-9.5) months. Compliance was good. Of the 1,131 cycles, only 13% had to be administered with a reduced dose and/or postponed to a later date. Toxicity was mild and grades 3 and 4 toxicities were uncommon. Two toxic deaths were registered though. CONCLUSION: The response rate and the OS for this low toxicity regimen makes it a feasible alternative for not cisplatin eligible patients.

RESUMO

In this article, we present a case study of residents' clinical experiences and communication in outpatient oncology consultations. We apply positioning theory, a dynamic alternative to role theory, to investigate how oncology residents and patients situate themselves as persons with rights and duties. Drawing from seven qualitative interviews and six days of observation, we investigate the residents' social positioning and their conversations with patients or supervisors. Our focus is on how (a) relational shifts in authority depend on each situation and its participants; (b) storylines establish acts and positions and narratively frame what participants can expect from a medical consultation viewed as a social episode; and (c) the positioning of rights and duties can lead to misunderstandings and frustrations. We conclude that residents and patients locate themselves in outpatient conversations as participants who jointly produce and are produced by patients' and nurses' storylines about who should take responsibility for treatment.

RESUMO

UNLABELLED: During follow-up on patients treated for differentiated thyroid cancer, thyroglobulin (Tg) antibodies can interfere with the Tg assay, making the use of Tg less reliable as a tumor marker. PURPOSE: To compare Tg and Tg autoantibodies (Tg-Ab) methods used in Denmark, regarding the number of patient samples being accepted for evaluating the result of a serum thyroglobulin (s-Tg) measurement. DESIGN: 95 consecutive blood samples drawn from patients in 2006 in one center were selected according to the following criteria: s-Tg <1µg/l and accepted BRAHMS Tg+ recovery test using 50 ng of Tg. Samples were retested with: (1) DPC IMMULITE 2000 Tg and Tg-Ab, (2) BRAHMS Tg and Tg-Ab on Kryptor, (3) BRAHMS Tg+ and Dynotest anti-Tg, (4) DELFIA hTg and recovery test using 25 ng of Tg, and (5) BRAHMS Tg+ with recovery test using 1 and 50 ng of Tg. RESULTS: The number of patient samples that was not accepted for Tg evaluation varied from 2 to 26% when the reference values suggested by the manufacturers of the assay were used. When using the detection limit to the cutoff seen in epidemiological studies the number increased to 40%. CONCLUSION: We found large discrepancies in acceptance of patient samples for s-Tg evaluation, thus illustrating a diagnostic dilemma.

RESUMO

INTRODUCTION: Treatment with a topoisomerase I inhibitor in combination with a platinum results in superior or equal survival compared with etoposide-based treatment in extensive disease small cell lung cancer (SCLC). Five-day topotecan is inconvenient and therefore shorter schedules of topotecan and cisplatin are needed. The aim of this phase II study was to establish the response rate and response duration in chemo-naive patients with SCLC receiving a 3-day topotecan and cisplatin schedule. METHODS: Simons optimal two-stage design was used. Patients with previously untreated extensive disease SCLC, adequate organ functions and performance status less than 3 were eligible. Topotecan (2.0 mg/m, intravenously) was administered on days 1 to 3 with cisplatin (50 mg/m, intravenously) on day 3 every 3 weeks for a total of six cycles. RESULTS: Forty-three patients received 219 cycles of chemotherapy. Median age was 59 (range 44-74), 79% had performance status 0 or 1. Thirty-one patients completed all six cycles. Grade 3/4 anemia, neutrocytopenia, and thrombocytopenia were recorded in 9.5%, 66.7%, and 21.4% of patients, respectively. Fourteen percent of patients experienced neutropenic fever. No episodes of fatal sepsis occurred. Non-hematologic toxicity was mild and manageable. Overall and complete response rates were 72.1% and 9.3%, respectively. The median overall survival and response duration were 10.3 months (95% confidence interval: 8.6-12.0) and 7.0 months (95% confidence interval: 6.3-7.7), respectively. CONCLUSION: Three-day topotecan with cisplatin on day 3 is active and safe in extensive disease SCLC. An ongoing phase III randomized trial compares this combination to standard treatment.

RESUMO

BACKGROUND: Most chemotherapeutics are administrated intravenously (iv), but some are also available in an oral (po) formulation. This study was designed with the primary objective to estimate the patients' preference for po or iv vinorelbine in combination with carboplatin for the palliative treatment of non-small cell lung cancer (NSCLC). Secondary aims were to evaluate toxicity, efficacy, and subjective reasons the preference. PATIENTS AND METHODS: Sixty-one patients were randomized in a cross-over trial to two cycles of carboplatin day 1 and vinorelbine day 1 and day 8 iv followed by two cycles of carboplatin and vinorelbine po, or the opposite. Patients, who did not show progressive disease after four cycles, had a free choice of iv or po vinorelbine for the next two cycles. RESULTS: Forty-three patients were evaluable for preference and 32 (74%, 95% CI 61-88%) chose po (p<0.001). The response rate was 23% and median survival 11.4 months. Patients with preference for po treatment stated that side effects were less with capsules and that daily life was less affected by capsules. CONCLUSION: Three out of four patients preferred oral vinorelbine. Clinical outcomes were comparable to other combination chemotherapy regimens for NSCLC.

RESUMO

PURPOSE: We wanted to study whether an allogeneic melanoma lysate would be a feasible stimulatory antigen source for detection of a peripheral CD4+ T-cell immune response in patients with medically untreated malignant melanoma. The lysate was produced from a melanoma cell line (FM3.29) which expresses high amounts of melanoma antigens. METHODS: Fresh peripheral blood was incubated with and without lysate for 6 h in the presence of anti-CD28/anti-CD49d MoAb (for costimulation). After flow cytometric estimation of the frequency of CD69+/IFN-gamma+ cells in the CD4+ population, the response to lysate was calculated as the difference between the number of activated IFN-gamma-producing CD4+ cells in the lysate-stimulated and the nonstimulated sample. RESULTS: An immune response to lysate was observed in blood samples from 11 of 15 patients (73%) with metastatic melanoma. A weak response was found in 1 of 4 patients radically operated for localized disease, whereas no responders were seen among 7 healthy donors. The fraction of circulating lysate-activated T cells ranged from 0.0037% to 0.080% of the CD4+ population. A negative result of the assay was found occasionally, especially in donors with high background levels of spontaneous IFN-gamma production, indicating an inhibitory effect of the lysate. CONCLUSIONS: This method for detection of a peripheral T-cell immune response in melanoma patients has several advantages for clinical use. The tumor lysate preparations may contain large numbers of stimulating antigens (known, as well as unknown) and are easily prepared and handled. Potentially, the assay might be useful as a diagnostic tool, a marker of residual or recurrent disease, a prognostic factor, or a predictor or monitor of the effect of antineoplastic therapy including immune-modulating therapy.
