RESUMO

Malignant pheochromocytoma is a tumour with a very low incidence that occurs sporadically or in the presence of multiple endocrine neoplasia. We present the case of a woman with a sporadic occurrence of pheochromocytoma diagnosed in the phase of multiple dissemination in the abdominal cavity and overexpressing adrenaline, noradrenaline, and dopamine. Local transarterial chemoembolization and systemic treatment with lanreotide resulted in a very good response, a decrease in the production of catecholamines for 12 months and a partial decrease for another 8 months, with stabilization of disease determined by imaging. Systemic treatment with tegafur resulted in disease stabilization lasting 50 months, after which the drug was discontinued because of adverse effects. Maintenance therapy with lanreotide continues, and no disease progression has been observed for 4 months. The treatment algorithm for such patients is multidisciplinary and must always take into account the current scope of the disease, intercurrence, and the general condition of the patient.

RESUMO

BACKGROUND: Schnitzler syndrome is a very rare, acquired, autoinflammatory disease of mostly adult onset with characteristic combination of chronic recurrent urticaria and monoclonal immunoglobulin M or G gammopathy predisposing the patients to malignant lymphoproliferation. In this work, we analyzed the results of bio-logical therapy with anakinra on a national level aiming to supply data for effective pharmaco-economic estimates, lay the grounds of nationwide patient registry, raise awareness among professional public and optimize provided health care. PATIENTS AND METHODS: The retrospective study (10/ 2006- 9/ 2013) included six males with definite Schnitzler syndrome verified by the new Strasbourg criteria. All patients were pretreated with antihistamines, nonsteroidal antiinflammatory drugs and glucocorticoids. Four patients underwent two or more treatment lines including intravenous bisphosphonates, 2- chlorodeoxyadenosine (cladribine), interferonα, PUVA photochemotherapy, cyclosporine A, thalidomide, bortezomib, chlorambucil, cyclophosphamide, colchicine and methotrexate. Anakinra monotherapy was initiated in standard dosing (100 mg subcutaneously daily). RESULTS: Complete and partial remissions were achieved in five (83%) and one patients (17%), respectively. Complete remission was characterized by urticaria and pain regression (within hours), normalization of inflammatory markers (with--in days) and bone metabolism improvement assessed by the markers of osteoblastic osteoformation and osteoclastic osteoresorption in one case (within weeks). With normalized inflammatory markers (including interleukin6 and interleukin18), arthralgia and sporadic exacerbations of urticaria and fevers persist in the patient in partial remission with proven Q703K polymorphism in NLRP3 gene. The median treatment followup was 30.5 months (37.2 ± 31.2 (n = 6)). The dosing interval was prolonged in one case of complete remission to 48 hours. No serious adverse reactions occurred during anakinra application. CONCLUSION: In Schnitzler syndrome, anakinra represents an effective, verified and safe medication with potentionally longterm administration not compromising its original efficacy and subjective tolerance. Anakinra, blocking autonomous inflammatory reaction of the organism via interleukin1 pathway, is a generally accepted first line treatment that should be made available in standard dosing for all Schnitzler patients.

RESUMO

BACKGROUND: The primary aim of palliative treatment is to improve the quality of life, followed by prolongation of overall survival. The effective regimens are usually complicated by increased side effects, particularly hematologic. Under these conditions, useful treatment is difficult and less effective. CASE: We present the case of a patient with cancer of the abdominal and pelvic cavity (the origin was likely an ovary). The patient was treated with intensive chemotherapy (15 cycles of carboplatin and paclitaxel) and supportive care (30 doses of epoetin alpha and 2 doses of 48MIU G-CSF for neutropenia G4). CONCLUSION: A good quality of life and long-term persistent complete remission (6 months) was achieved, no transfusion, no hospitalization. Overall survival was 61 months.

RESUMO

The number of malignant diseases increases and the question is why. Why is there an increasing incidence of certain cancers and why an increasing number of people dies from them? We do not have a clear answer to these questions. We just know that a development of cancer depends on certain internal predispositions as well as external conditions. We are unable to change our genetic predisposition but we are able, to some extent, influence the intensity of external factors. This paper summarizes information on the effects of external environment on the development of malignant diseases.

RESUMO

High-risk human papillomavirus (HPV) are implicated in the development of a subset of head and neck cancers, especially those arising from the lingual or palatine tonsils. HPV-associated cancer of the head and neck represent a different disease entity from those associated with the traditional risk factors of tobacco and alcohol use. There has been as increase in the annual incidence of HPV-related cancers in Europe and USA in the past years. It has now become clear that a subset of the head and neck tumors is a sexually transmitted disease with distinct pathogenesis and clinical and pathological features. Research efforts are now focusing on deintensification of treatment to reduce treatment associated morbidity. The potential application of HPV targeted terapies in HPV associated cancers is an area of active research.

RESUMO

Head and neck squamous cell cancer (HNSCC) management is evolving rapidly. Approaches under exploration include induction chemotherapy, altered fractionation radiation with chemotherapy, intensity modulated radiation therapy (IMRT) and the use of biologically targeted drugs to enhance radiation. The goal of the new methods is improving the effectivity without increasing the toxicity. This article will focus maily on locally advanced HNSCC, which frequently remains a clinical challenge, review state-of-the-art therapy and introduce promising novel terapies. For the future the incorporation of new agents, the use of novel biomarkers to accurately assess and individualize therapy, and expanded supportive care approaches will play an increasingly important role.

RESUMO

Twenty-five evaluable pediatric patients with histologically proven Burkitt's lymphoma were treated with moderate dose combination chemotherapy consisting of cyclophosphamide, vincristine, methotrexate and cytosine arabinoside (COMA regime) without central nervous system prophylaxis. Complete remission was achieved in 94.1% (16/17) of patients with Stage I, I R, II and III A disease, with disease-free survival of more than 3 years. This protocol was attended by minimal chemotherapeutic toxicity. This combination chemotherapy was ineffective in more advanced disease (Stages III B, IV), major cause of failure being progressive disease with central nervous system involvement. This study showed the effectiveness of moderate dose chemotherapy without CNS prophylaxis in early stage Burkitt's lymphoma including Stage III A and needs for aggressive chemotherapy with CNS prophylaxis in more advanced disease.

RESUMO

Between April 1986 and May 1989 a multicentre study was conducted to evaluate the efficacy of a 4-h intravenous infusion of 1000 mg/m2 5-fluorouracil (5-FU) followed by a 1-h infusion of 25 mg/m2 cisplatin (CDDP) given for 4 consecutive days every 4 weeks to patients with advanced squamous-cell carcinoma of the head and neck. A total of 189 consecutive patients entered the study, including 106 who had previously undergone chemotherapy and 83 who were chemotherapy-naive. Of the 165 evaluable patients, 96 (58%) responded to treatment, including 22 (13%) who achieved a complete remission (CR). In the group of previously untreated patients an objective response (CR+PR) was seen in 78% (CR, 14%) whereas in pretreated patients the response rate (CR+PR) was 40% (CR, 13%). The median survival period was 10 months. No significant difference in the duration of survival or of remission was found between the two groups in relation to previous therapy, tumour localisation, disease stage or performance status. Almost half of the patients (49%) experienced leucopenia but it was severe in only 11% of cases. Anemia (mainly WHO grades 1-2) occurred in 38% of the patients. Nausea and vomiting were common (84%). Nephrotoxicity (23%) was mild and of short duration. Moderate hair loss was seen in 42% of the patients, and phlebitis occurred in 8%. A few cases of cardiotoxicity and neurotoxicity were observed. This regimen is well tolerated and can be given even on an outpatient basis. The resultant response rate and side effects appear to be similar to those previously reported for combination chemotherapy with CDDP and continuous 5-FU infusion.

RESUMO

In a multicentre study patients with liver metastases stratified to the histology of the primary tumour were investigated. A total of 102 patients with colorectal adenocarcinoma, non-small-cell lung cancer, pancreatic cancer, primary liver carcinoma and malignant melanoma were treated with the thioether lipid ilmofosine. The drug was administered orally as a tablet at a dosage of 150-300 mg/day (75 mg/tablet). The tolerability of ilmofosine was poor. There was a dose-limiting gastrointestinal toxicity with nausea, vomiting and loss of appetite (WHO grade II-IV) in 67% of patients. During the period of therapy (1-29 weeks, 8.5 weeks mean) no complete remission and no partial response were observed. We thus conclude that treatment with oral ilmofosine is not effective in patients with liver metastases due to various malignancies.

RESUMO

One hundred and eleven previously untreated patients with extensive small cell lung cancer were included in a prospective randomized study with the aim to assess the efficacy and tolerance of high-dose epirubicin (120 mg/m2) in combination with either cyclophosphamide (800 mg/m2; arm 1) or cisplatin (60 mg/m2; arm 2). Ninety-six patients were evaluable for response and toxicity and additional 12 patients for toxicity only. The overall response rate (CR+PR) in arm 1 and 2 were 61.4 (27/44) and 67.3% (35/52), respectively. The mean duration of remission was 4.4 months (arm 1) and 4.9 months (arm 2). The mean survival time was 6.6 months in arm 1 and 7.7 months in arm 2. WHO grade 4 toxicity was encountered in 25.5 and 15.8% of patients in arm 1 and 2, respectively. One case of cardiotoxicity resulting in the patient's death was observed in arm 1. Both combinations showed considerable antitumor activity. Toxicity was acceptable.

RESUMO

On the basis of results obtained with oral idarubicin administration in breast cancer, which have shown an established antitumor activity in approximately 28% of cases, this compound was combined with cyclophosphamide (also given orally) in postmenopausal patients with an unknown or negative steroid receptor status. The study comprised 45 untreated patients out of which 44 were evaluable for response and toxicity. The mean age was 62.5 years (range 51-75). The majority of patients had soft tissue (24) and visceral organ (17) metastases. Idarubicin was administered in one oral daily dose of 45 mg/m2 on day 1; the oral cyclophosphamide dose was 200 mg/m2 daily on days 3, 4, 5 and 6. An objective response to treatment was observed in 41% of patients (18/44, 95% confidence interval 28-56%). Complete remission (lung) was observed in 2 patients (5%), while 16 patients achieved a partial response. Eleven patients showed no change, while 15 patients progressed. A particularly good response was obtained in soft tissue metastases (54%, 13/24) while in visceral organs a response was achieved in 31% of patients (5/16). The remissions lasted 2-14 months (median 7 months), and median survival was 14+ months. Toxicity was mild and the treatment well tolerated. Grade I/II leukopenia was observed in 24% of patients (median WBC nadir 3,100); there were no signs of cardiotoxicity. Grade I and II alopecia was observed in 75% of patients: nausea/vomiting were present in 73% of cases. The results of this study indicate that oral administration of idarubicin and cyclophosphamide produces a valuable antitumorigenic effect in postmenopausal breast cancer patients, particularly in soft tissue metastases. Further randomized studies will be needed to evaluate this treatment approach.

RESUMO

The purpose of the study was to investigate the antitumour activity and toxicity of high dose (120 mg m-2) single agent epirubicin therapy in untreated extensive small cell lung cancer patients. Out of 80 patients entered, 71 were evaluable for both antitumour activity and toxicity, 4 only for toxicity and 5 were lost for follow-up. The drug possessed a high antitumour activity, the overall response rate was 47.9% (34/71) with 4 complete remissions (CR) and 30 partial remissions (PR). The median remission duration was 3.5 months. Particular drug activity was observed in the primary tumours, lymph nodes and pleural metastases. Toxicity (leukopenia, anaemia, vomiting, reversible rhythmic cardiac disorder, stomatitis) was mild, alopecia was registered less than in adriamycin medication. One fatal congestive heart failure occurred. The actual mean survival time calculated on the basis of the data gained from 64 patients was 7.0 months (range 2-22). The high antitumour activity and no increase in toxicity justify the incorporation of high dose epirubicin into combination therapy.

RESUMO

The objective of this trial was to define the antitumor activity and toxicity of etoposide for second-line treatment of patients with bulky ovarian carcinoma. Between February 1, 1986 and November 1, 1988 we recruited 82 patients. Out of them 77 (93.9%) were evaluable for toxicity and 71 (86.6%) for response. Patient characteristics are as follows: median age 57 years (range 15-75), median performance status: WHO 1, prior chemotherapy with more than 3 drugs 24 patients, with previous cisplatin 63 patients, with previous adriamycin 47 patients, with previous irradiation plus chemotherapy 17 patients. The following treatment schedule was applied: each patient started with 150 mg/m2 of etoposide administered i.v. on days 1-3. If this first cycle was well tolerated the dosage was escalated to 200 mg/m2 days 1-3. This higher dosage was then repeated at 4-week intervals. For evaluation of response the WHO criteria were used. One patient (1.4%) achieved complete remission and 5 (7.0%) partial remission. In 48 patients (67.6%) minor response or stabilisation of the disease were observed. Seventeen patients (24%) showed no response. The median duration of remission was 5.5 months (range 2-20). The median duration of stabilisation was 3 months (range 2-24). The median survival time was 10 months with a range of 2-30 months. The myelotoxic side-effects are as follows: WBC less than 2,000 was recorded in 6 patients and greater than 1,000 in 2 patients. Thrombocytopaenia with platelet count less than 50,000 occurred in 1 patient. 26 patients had anaemia WHO grades 2 and 3. Non-haematological toxicity consisted of nausea and vomiting (WHO grade 2:20 patients and grade 3:2 patients), alopecia (WHO grades 2-3:14 and 24 patients, respectively). Though the remission rate in this trial was low, the 10-month median survival with an acceptable quality of life can be taken as a fairly good salvage therapy result.

RESUMO

Multinucleated cells (MC) were counted in cell preparations obtained by dissociation of representative part of tumor lesions immediately after excision. MC were present in almost all specimens examined (39 advanced primary lesions, 90 lymph node metastases and 33 dermal plus subcutaneous metastases); in one third of the samples they were very rare (less than 1% of all cells). There were no significant differences in quantity of MC between primary tumors, node metastases and dermal plus subcutaneous metastases, between node metastases seen early in the course of the disease and those seen later, and between regional node metastases taken from Stage II patients with rapidly progressing disease and regional node metastases taken from patients of the same stage whose disease-free intervals were longer. No unique pattern of similarities or differences in quantity of MC was found when comparing autologous tumor samples excised simultaneously and/or successively during the course of the disease.

RESUMO

Melanoma cells freshly isolated from regional lymph node metastases of 59 stage II malignant melanoma patients were analyzed by indirect immunofluorescence staining with monoclonal antibody TAL 1B5, detecting the HLA-DR alpha chain. The expression of HLA-A,B,C antigens, using antibody W6/32, was also investigated in 45 of these cases. There were no substantial differences in the course of the disease with respect to the percentage of positive cells. In 13 malignant melanoma patients two to four simultaneous and/or successive metastases (both locoregional and distant-subcutaneous) were analysed for HLA-DR. With simultaneous metastases (7 cases) the percentage of HLA-DR-positive cells was mostly very similar, and in no case was there more than 25% variation. As to successive metastases (9 cases) the percentage of HLA-DR-positive cells remained practically unchanged or decreased during the course of the disease.

RESUMO

To assess the clinical value of two comparatively new properties (DNA content and MHC class II antigen expression (HLA-DR, DP, DQ) of melanoma cells) which have been independently reported to reflect the outlook for patients with malignant melanoma, we investigated retrospectively 50 stage I nodular melanomas in two comparably homogeneous groups of 23 and 27 patients, the course of whose disease differed at five years. Flow cytometry and immunohistology were used on paraffin wax embedded archival material for the analysis of DNA ploidy and detection of class II antigens, respectively. A close association was found between class II antigen expression, detected by monoclonal antibody CR3/43 (antimonomorphic DR, DP, DQ) present in 23 of 50 (46%) melanomas and unfavourable clinical course (p less than 0.005, by log rank test), but no such association was found for DNA ploidy. It is suggested that immunohistology for MHC class II antigen expression may help to predict the behaviour of nodular melanomas whereas the prognostic value of DNA ploidy is more limited. The finding that class II positive cells are found predominantly in melanomas with a substantially increased risk of metastases has implications both for concepts of tumour heterogeneity and host immunity.

RESUMO

Phase II studies of p.o. Idarubicin administration, a new daunorubicin analogue (4-demethoxy-daunorubicin), have shown antitumor activity in 23%-31% of previously treated metastatic breast cancer patients, while in untreated patients a response rate of 41% was observed. Our Phase II study has shown an overall response of 23% [1 complete response (CR), 9 partial response (PR), 10/43] with a daily dose of 15 mg/m2 p.o. on days 1,2,3. On the basis of these results we have recently included Idarubicin in combination chemotherapy of breast cancer, substituting Adriamycin by Idarubicin in an FAC schedule. Of 50 consecutive metastatic breast cancer patients who entered the study, 42 patients who received greater than 2 cycles were evaluable. There were 22 premenopausal and 20 postmenopausal patients (mean = 51 years). In 25 patients a performance status of 0-2 (ECOG) was registered and in 17 patients it was 3. Previous radiation had been administered in 34, hormonal therapy in 18, and adjuvant chemotherapy (CMF 5, CMFVP 3) in 8 patients; 22 patients had predominant metastatic sites in soft tissues, 18 in visceral organs, and 2 in the bones. The FIC schedule was administered as follows: 5-fluorouracil 500 mg/m2 i.v. days 1 and 8, Idarubicin 15 mg/m2 p.o. days 1, 2 and 3, and cyclophosphamide 500 mg/m2 i.v. day 1. An objective response was observed in 23 (5 CR, 18 PR) out of 42 patients (53%, CR 12%). Soft tissue metastases responded in 55% (12/22), visceral organs in 61% (11/18), and no response was observed in bone lesions (0/2). The median remission duration was 8 months (3-16+). Toxicity was mild, expressed mainly in the form of nausea/vomiting, grade I and II in 64% of the patients. Alopecia was very mild (grade I and II in 23% of the patients). Leukopenia grade I-II was observed in 21% of the patients. In 4 patients reversible ECG changes occurred. Left ventricular ejection fraction did not show any pathological changes. The Idarubicin-containing combination chemotherapy we have used has the following characteristics: easier administration (p.o. anthracycline, no risk of tissue extravasation), lower toxicity (cardiotoxicity, alopecia, and myelosuppression in particular), and a notable antitumor activity.

RESUMO

Skin tests with autologous cholesteryl hemisuccinate-treated tumor cells were performed in Stage II malignant melanoma patients. In the majority of cases an evident reaction having features of delayed type hypersensitivity was noted. No significant correlation between this reactivity and subsequent course of the disease was found. The same was true for the results of DNCB and PPD skin testing. An analysis of the results of all three tests in the same patient revealed no prognostic significance of this score either.
