RESUMEN

OBJECTIVES: The association between depressive symptomatology and endogenous testosterone levels is inconclusive. Large inter- and intra-individual testosterone differences suggest point measurements from saliva or serum to be inadequate to map basal testosterone concentrations highlighting the potential for long-term integrated testosterone levels from hair. METHODS: Using data from a prospective cohort study, a total of 578 participants (74% female) provided complete data on depressive symptomatology, clinical features, and hair samples for quantification of testosterone concentrations at baseline. Available data of three annual follow-up examinations were used for longitudinal analyses. RESULTS: Correlation analysis showed in both, men and women, hair testosterone across all the four time points not to be significantly related to depressive symptoms. Examined clinical features were not associated with testosterone levels, except for having a current diagnosis of a psychological disorder, which was associated with reduced testosterone levels in men, but not in women. Acceptable model fit for an autoregressive cross-lagged panel analysis emerged only for the female subsample suggesting inverse cross-relations for the prediction of testosterone by depressive symptomatology and vice versa. CONCLUSIONS: Findings from this study add to the literature by showing no association between long-term integrated testosterone in hair and depressive symptomatology in men and women.

RESUMEN

It is debated as to whether major depressive disorder (MDD) and the burnout syndrome represent different aspects of the same syndrome or whether they reflect separate entities. A dysregulation of the hypothalamus-pituitary-adrenal-axis has been related to both conditions separately. Dissecting the pathophysiology of the conditions and describing differences and similarities with regard to stress physiological systems might further clarify whether underlying etiological models of these syndromes differ. A systematic literature search including MDD and the burnout syndrome and peripheral cortisol measures was performed and resulted in 190 studies for inclusion in the qualitative synthesis. For MDD, findings suggest a general state of hypercortisolism and glucocorticoid resistance reflected by increased basal cortisol levels, reduced reactivity to psychosocial stress and a reduced cortisol suppression in pharmacological challenge tests. For the burnout syndrome, two central factors limit further conclusions: i) there is not a sufficient amount of studies examining the burnout syndrome and different cortisol secretion patterns to provide an evidence base, ii) the burnout syndrome is assessed heterogeneously reflecting imprecision of the measured constructs. Large prospective cohort studies examining both conditions in parallel rigorously controlling for confounders are required to further elucidate the differences and similarities of the HPA axis in MDD and the burnout syndrome.

RESUMEN

The International Classification of Functioning, Disability and Health (ICF) does not yet classify personal contextual factors. To determine the interaction of these factors on activities and participation of a person as well as their influence on the probable outcome of interventions, they must be taken into account in individual sociomedical expertises. Therefore, a group of medical experts working for the social health insurance medical advisory boards in Germany compiled a proposal for a systematic classification of personal contextual factors into domains, categories and items with respect to the ethical guidelines of the ICF. In a second step the main issues were transferred into the preliminary draft for a short version which will be published later to give support for practical daily use in health insurance matters.

RESUMEN

PURPOSE: A multicenter phase II trial was performed to investigate the efficacy and tolerance of docetaxel, vinorelbine with or without recombinant human granulocyte colony-stimulating factor (G-CSF) in patients with metastatic breast cancer. PATIENTS AND METHODS: Between February 1998 and March 1999, 57 patients participated in this trial. Forty-two patients received this combination as first-line and 15 patients as second-line chemotherapy, including 10 patients who had failed anthracyclines. Therapy consisted of vinorelbine 30 mg/m(2) on days 1 and 15 and docetaxel 30 mg/m(2) on days 1, 8, and 15 every 4 weeks. Depending on the absolute neutrophil counts on the day of scheduled chemotherapeutic drug administration, a 5-day course of G-CSF 5 microg/kg/d was given. RESULTS: The overall response rate was 64.3% (95% confidence interval, 48.1% to 78.4%) in patients receiving docetaxel plus vinorelbine as first-line chemotherapy, including eight complete (19%) and 19 partial remissions (45.3%); 11 patients (26.2%) had disease stabilization, and only four (9.5%) progressed. Second-line treatment with this regimen resulted in eight (53.3%) of 15 objective responses, four had stable disease, and three had progressive disease. The median time to progression was 12 months in the first-line and 9.8 months in the second-line setting, respectively. After a median follow-up time of 18 months, 38 patients (65%) were still alive with metastatic disease. Myelosuppression was commonly observed; World Health Organization grade 3 or 4 neutropenia both occurred in 18 patients (32%) and was complicated by septicemia in four cases; grade 3 or 4 thrombocytopenia was seen in two patients (4%), and grade 3 anemia was seen in only one patient (2%). Severe (grade 3) nonhematologic toxicity, except for alopecia, was rarely observed and included nausea/vomiting in two patients (4%), and stomatitis, peripheral neuropathy, and skin toxicity each in one patient. CONCLUSION: Our data suggest that docetaxel and vinorelbine with or without G-CSF is an effective and fairly well tolerated regimen for the treatment of advanced breast cancer. It might be particularly useful in patients previously exposed to adjuvant or palliative anthracyclines and/or alkylating agents.

RESUMEN

1. The S,S (-)-enantiomer PD 129290, a kappa agonist, and its corresponding inactive R,R (+)-enantiomer (PD 129289) were studied in rat isolated hearts and in intact rats for cardiovascular and antiarrhythmic actions. The electrophysiological actions of PD 129290 were also studied in rat isolated cardiac myocytes using voltage clamp. 2. Ventricular pressure, heart rate and ECG were studied in isolated hearts while blood pressure, heart rate and ECG were studied in pentobarbitone-anaesthetized rats. In the latter, responses to electrical stimulation and coronary occlusion were also investigated. 3. In isolated hearts both enantiomers, over the concentration range 2-16 microM, dose-dependently reduced systolic ventricular pressure and heart rate while prolonging the P-R and QRS intervals of the ECG. 4. At doses of 1-32 mumol kg-1 both enantiomers reduced blood pressure and heart rate in anaesthetized rats. In addition, both enantiomers increased the size of the RSh and increased P-R, QRS, and Q-T intervals of the ECG. The thresholds for premature beats and ventricular fibrillation were dose-dependently increased by PD 129289. At lower doses PD 129290 decreased thresholds. These decreases were blocked by naloxone to reveal underlying increases similar to those seen with PD 129289. Both enantiomers increased refractory periods. 5. Naloxone (8 mumol kg-1) did not alter any of the actions of PD 129290, except to abolish the initial decreases in thresholds in intact rats seen with lower doses of PD 129290. 6. Both enantiomers (2 and 8 mumol kg-1) equally reduced arrhythmias in anaesthetized rats subject to occlusion of a coronary artery. 7. In rat isolated cardiac myocytes 20 microM PD 129290, in the presence and absence of naloxone decreased the amplitude of the transient sodium current by about 50% without affecting the voltage dependence of activation or inactivation of this current.8. The antiarrhythmic actions of both enantiomers appear to primarily result from their Class I(sodium channel blockade) properties which are independent of kappa agonism.

RESUMEN

BACKGROUND: Serum levels of beta-2 microglobulin (B2M) have been reported as a predictor of clinical outcome, prognosis and tumor burden in patients with various types of lymphomas. In case of lymphoma of the mucosa-associated lymphoid tissue (MALT)-type, no clear data exist to define the role of B2M in terms of staging or prognosis. In a retrospective analysis we investigated the serum B2M-levels in patients suffering from histologically verified MALT-type lymphoma in correlation to stage and response to treatment. PATIENTS AND METHODS: All patients admitted to our institution since 1996 with a diagnosis of MALT-type lymphoma were retrospectively evaluated for staging procedures and measurements of serum B2M levels. Patients with a staging work-up including otorhinolaryngologic evaluation, gastroscopy with multiple biopsies, endosonography of the upper GI-tract, enteroclysis, colonoscopy, CT of thorax and abdomen and bone marrow biopsy were analysed, while staging was performed according to the Ann Arbor system as modified by Musshoff. In addition, only patients with histologic samples amenable to re-assessment by a reference pathologist were included. RESULTS: A total of 68 patients with a diagnosis of MALT-type lymphoma were identified from our records. However, only in 32 patients exact staging according to our inclusion criteria had been performed and serum B2M-levels prior to the initiation of therapy were available in all these patients. Twenty-five patients; suffered from gastric lymphoma, while the remaining 7 patients had extragastric manifestations. In total, 13 out of 32 patients presented with stage I disease, 17 patients were rated as stage II and 2 patients suffered from stage III disease. Nineteen patients had elevated B2M-levels prior to therapy: 6 patients were rated as stage 1, II had stage II and two had stage III disease. Five patients still had elevated B2M-levels following treatment despite radiologically and histologically verified complete remission. CONCLUSION: In this series, no correlation between serum B2M levels, tumor burden and clinical outcome was apparent in patients with MALT-type lymphomas. While the number of patients with disseminated disease was small we could not demonstrate a difference for B2M-levels between stage I and stage II. While we cannot rule out that B2M might be different in patients with stage I/II disease as compared to more advanced disease, further investigations are necessary to determine the role of this marker in patients with MALT-type lymphoma.

RESUMEN

Geriatrics is needed as an independent discipline to cope with the demographic challenges ahead in a medically qualified manner. Geriatrics is a "supraspeciality" and not a "subspeciality" of Internal Medicine, because geriatrics typically combines the different medical disciplines and does not play a role as an independent functional area. For general practitioners and medical specialists a geriatric qualification is required. The geriatric structures in place in the German federal states need to be adapted and advanced with a focus on ambulatory geriatric service provision. The current health care reform has resulted in a strengthening of rehabilitation in general and in particular of an ambulant/mobile service approach. The resultant opportunities and risks are described. Internal and external quality assurance is indispensable for the advancement of structures including geriatrics and social medicine.

RESUMEN

Carcinoid tumors may relapse after a long time span following initial diagnosis, and relapse might be clinically inapparent despite biochemical indications due to a low sensitivity of conventional methods. We present the case of a patient who had biochemical indication for hidden disease persistence for more than two decades. In 1978, a 39-year-old man underwent surgery for a carcinoid tumour of the ileum measuring 3.5 cm with multiple local lymph-node metastases. After surgery, however, serotonin- and urinary 5-hydroxy-indole-acetic-acid (5-HIAA) remained markedly elevated, and persisted over more than 20 years at levels between 600 and 950 ng/ml for serum serotonin (normal range 40-400 ng/ml) and 29-35 mg/24 h for 5-HIAA (normal range 2-9 mg/24 h). Despite this, regular radiological follow-up, including sonography and CT-scan, did not reveal the location of suspected malignancy until 1999, when the patient was re-admitted to our hospital for a hypertensive episode. CT-scanning of the abdomen showed a singular lesion within the liver, which was verified as recurrence of the carcinoid by fine needle biopsy. Somatostatin receptor scintigraphy using (111)In-DTPA-D-Phe1-Octreotide revealed a second lesion within the liver along with local recurrence at the anastomosis, which was verified by surgery. While the propensity for late relapse of ileal carcinoids has repeatedly been demonstrated, a case with biochemical signs of disease persistence over a time span of 21 years before final diagnosis is unusual. In addition, our case reflects the low sensitivity of conventional radiological evaluation for localization of carcinoid tumours as compared to somatostatin receptor scanning.

RESUMEN

BACKGROUND: Oxaliplatin is a novel cytotoxic agent with documented activity in colorectal cancer. Side effects are generally moderate, and include peripheral neuropathy along with mild bone marrow suppression and gastrointestinal side effects. To our knowledge, induction of febrile episodes by this agents has not been described in the literature. CASE REPORT: We present the case of a 74-year-old male patient admitted to our institution for palliative treatment of metastatic colorectal carcinoma. Due to progression during treatment with 5-fluorouracil and leucovorin, chemotherapy consisting of oxaliplatin 85 mg/m(2) on days 1 + 15 plus mitomycin C 8 mg/m(2) on day 1 repeated every 28 days was initiated. The first cycle of this combination was tolerated without side effects, but the patient experienced fever up to 39 degrees C starting 2 h after oxaliplatin administration on day 15 of the second cycle, which persisted for 3 days. Fever again recurred at the same interval following administration of oxaliplatin on day 1 of the next cycle. Blood samples taken at regular intervals disclosed an increase in IL-6 serum levels parallel to the body temperature curve, with the peak corresponding to the highest temperature, while C-reactive protein values remained unchanged. In spite of intensive premedication with steroids, antipyretics and clarithromycin, fever promptly recurred during the third cycle of treatment. CONCLUSION: Our data suggest a clear- cut correlation between fever, the release of IL-6 and oxaliplatin administration. Whether IL-6 release is directly triggered by the application of oxaliplatin or is a bystander phenomenon, however, remains unclear at the moment.

RESUMEN

BACKGROUND AND AIMS: Gastric MALT-lymphoma is thought to be related to chronic antigenic stimulation provided by Helicobacter pylori (HP). As clonal expansion of gastric B cells not related to HP has been demonstrated in patients with autoimmune disease (AD), we have analysed whether AD adversely influences response of MALT-lymphoma following HP-eradication. PATIENTS AND METHODS: Retrospective analysis of all patients with early stage gastric MALT-lymphoma treated with HP-eradication was performed. The presence of AD was evaluated by personal questioning for specific symptoms and serologically by analysis of rheumatoid factor, antinuclear antibodies and thyroid autoantibodies. RESULTS: A total of 22 patients were identified receiving only antibiotic treatment for initial management, and six presented with an autoimmune condition: three had Sjögren's syndrome, one polymyalgia rheumatica, one autoimmune thyroiditis along with psoriasis, and one patient had only autoimmune thyroiditis. Successful eradication of HP was achieved in all patients, and 15 of 22 patients (68%) achieved complete response of the lymphoma, while none out of the six patients with an autoimmune disorder responded to HP-eradication. CONCLUSION: Apart from questioning the role of HP in the development of lymphoma in such patients, these results suggest that patients with autoimmune disease might not be optimal candidates for HP-eradication even in case of early stage lymphoma.

RESUMEN

Lymphoma of the mucosa-associated lymphoid tissue (MALT) type usually arises in MALT acquired through chronic antigenic stimulation triggered by persistent infection and/or autoimmune processes. Due to specific ligand-receptor interactions between lymphoid cells and high-endothelial venules of MALT, both normal and neoplastic lymphoid cells display a pronounced homing tendency to MALT throughout the body. In the case of neoplastic disease these homing properties may be responsible for lymphoma dissemination among various MALT-sites. According to this concept, we have standardized staging procedures in all patients diagnosed with MALT-type lymphoma. All patients with MALT-type lymphoma underwent standardized staging procedures before treatment. Staging included ophthalmologic examination, otolaryngologic investigation, gastroscopy with multiple biopsies, endosonography of the upper gastrointestinal tract, enteroclysis, colonoscopy, computed tomography of thorax and abdomen and bone marrow biopsy. Biopsy was performed in all lesions suggestive for lymphomatous involvement, and evaluation of all biopsy specimens was performed by a reference pathologist. 35 consecutive patients with histologically verified MALT-type lymphoma were admitted to our department. Twenty-four patients (68%) had primary involvement of the stomach, five (15%) had lymphoma of the ocular adnexa, three (8.5%) had lymphoma of the parotid, and three (8,5%) of the lung. Lymph-node involvement corresponding to stage EII disease was found in 13 patients (37%), only one patient with primary gastric lymphoma had local and supradiaphragmatic lymph-node involvement (stage EIII). Bone marrow biopsies were negative in all patients. Overall, eight of 35 patients (23%) had simultaneous biopsy-proven involvement of two MALT-sites: one patient each had lymphoma of parotid and lacrimal gland, conjunctiva and hypopharynx, conjunctiva and skin, lacrimal gland and lung, stomach and colon, and stomach and lung. The remaining two patients had bilateral parotideal lymphoma. Staging work-up was negative for lymph-node involvement in all of these eight patients. The importance of extensive staging in MALT-type lymphoma is emphasized by the demonstration of multiorgan involvement in almost a quarter of patients. In addition, our data suggest that extra-gastrointestinal MALT-type lymphoma more frequently occurs simultaneously at different anatomic sites than MALT-type lymphoma involving the GI-tract.

RESUMEN

PURPOSE: A phase II study was performed to investigate the efficacy and tolerance of alternating docetaxel and epirubicin/cyclophosphamide plus recombinant human granulocyte colony-stimulating factor (G-CSF) in patients with advanced breast cancer who failed previous non-anthracycline/taxane-containing palliative chemotherapy. PATIENTS AND METHODS: Between November 96 and June 98, a total of 45 patients participated in this trial. Chemotherapy consisted of docetaxel 100 mg/m2 given as a 1-h infusion on day 1, and epirubicin 100 mg/m2 plus cyclophosphamide 800 mg/m2 both administered on day 21. G-CSF 5 microg/kg/day was given subcutaneously from days 22-28 during each cycle. Treatment courses were repeated every 42 days for a total of three courses unless prior evidence of progressive disease. RESULTS: The overall response rate was 57.8% (95% confidence interval, 42.1-72.3%), including seven complete (15.5%) and 19 partial remissions (42.3%); nine patients (20%) had stabilization of disease and 10 (22.3%) progressed. The median time to treatment failure was 7.0 months (range 1.5-26.0), and the median overall survival time 15.0 months (range 2.0-37.0+) with 12 patients (27%) currently still alive with metastatic disease. Myelosuppression was commonly observed with WHO grade 3/4 neutropenia in 20 patients (44%) complicated by septicemia in five (11%). Severe nonhematologic toxicity included stomatitis in five patients (11%), skin and peripheral neurotoxicity each in one patient; alopecia was seen in all 45 patients with complete hair loss in 26 (58%). CONCLUSIONS: Our data suggest that alternating docetaxel and epirubicin/cyclo-phosphamide plus G-CSF is an effective and tolerable second-line combination regimen for the treatment of advanced breast cancer.

RESUMEN

BACKGROUND: Patients with advanced biliary tract carcinoma face a particularly dismal prognosis, and no standard palliative chemotherapy has yet been defined. Among several different single agents, mitomycin C and, more recently, the oral fluoropyrimidine capecitabine and the nucleoside analogue gemcitabine, have been reported to exert antitumour activity. In view of a potential drug synergy, the present randomised phase II trial was initiated. The aim was to investigate the therapeutic efficacy and tolerance of mitomycin C (MMC) in combination with gemcitabine (GEM) or capecitabine (CAPE) in previously untreated patients with advanced biliary tract cancer. PATIENTS AND METHODS: A total of 51 patients were entered in this study and randomly allocated to treatment with MMC 8 mg/m2 on day 1 in combination with GEM 2000 mg/m2 on days 1 and 15 every 4 weeks, or MMC 8 mg/m2 on day 1 plus CAPE 2000 mg/m2/day on days 1-14, every 4 weeks. In both arms, chemotherapy was administered for a total of 6 months unless progressive disease occurred earlier. RESULTS: Pretreatment characteristics were well balanced between the two treatment arms. The overall independent review committee-confirmed response rate among those treated with MMC + GEM was 20% (five of 25) compared with 31% (eight of 26) among those treated with MMC + CAPE. Similarly, median progression-free survival (PFS; 4.2 versus 5.3 months) and median overall survival (OS; 6.7 versus 9.25 months) tended to be superior in the latter combination arm. Chemotherapy was fairly well tolerated in both arms, with a comparably low rate of only grade 1 and 2 non-haematological adverse reactions. Also, only four (17%) patients in both treatment arms experienced grade 3 leukocytopenia, and three (13%) and four (17%) had grade 3 thrombocytopenia in the MMC + GEM and MMC + CAPE arm, respectively. CONCLUSIONS: The results of this study indicate that both combination regimens are feasible, tolerable and clinically active. The MMC + CAPE arm, however, seems to be superior in terms of response rate, PFS and OS, and should therefore be selected for further clinical investigation in advanced biliary tract cancer.

RESUMEN

BACKGROUND: Oxaliplatin and raltitrexed both are active anticancer agents in the treatment of patients with advanced colorectal carcinoma: They have different mechanisms of action and toxicity profiles and have shown at least additive effects in experimental and preliminary clinical studies. The aim of this disease oriented Phase I-II study was to determine the maximum tolerated dose (MTD), the dose-limiting toxicities (DLT), and the objective response rate of this combination in patients with advanced colorectal carcinoma. METHODS: Between April 1998 and March 1999, 69 patients with measurable metastatic colorectal carcinoma who previously were unexposed to palliative chemotherapy were enrolled. In the Phase I part of the study, 27 patients were treated with 3-weekly courses of a fixed dose of raltitrexed (3 mg/m(2) given as a 15-minute intravenous infusion) followed by a 2-hour infusion of oxaliplatin, which was escalated in consecutive cohorts of three to six patients from 85 mg/m(2) to 100 mg/m(2), 120 mg/m(2), 130 mg/m(2), and 140 mg/m(2). After having defined the toxic dose, 42 additional patients were entered at one dose level below to define the therapeutic index of this combination more precisely. RESULTS: In the Phase I part of the study, during the first three dose levels, only one patient each experienced DLT (Grade 3 increase in transaminases, diarrhea, and stomatitis); at level 4, two of the first six patients entered had Grade 3 neutropenic infection or peripheral neurotoxicity, whereas dose level 5 (oxaliplatin 140 mg/m(2)) constituted the toxic dose with three of three patients experiencing DLT (Grade 3 asthenia, transient amaurosis, and diarrhea with Grade 4 neutropenia). Externally reviewed objective responses were noted in 9 of these 27 patients (33%), and stable disease occurred in 12 patients (44.4%). Among the 42 patients who were treated subsequently at the MTD level (Phase II portion), 20 patients (47.6%) responded (95% confidence interval, 32-62.6%), and 21 patients (50%) had stable disease. Their median progression free survival was 9.0 months, and the median overall survival, with 42 patients (67%) currently alive, is > 14.5 months. Treatment tolerance at the MTD was acceptable, with only 9 of 42 patients (21%) experiencing Grade 3-4 neutropenia; Grade 3 nonhematologic adverse reactions included increase in serum transaminases in 6 patients, peripheral neuropathy in 3 patients, diarrhea in 3 patients, and both stomatitis and emesis in only 1 patient each. CONCLUSIONS: The described objective response and toxicity data, which are in agreement with preliminary results of other Phase I-II studies, support the promising therapeutic potential of this combination in the treatment of patients with advanced colorectal carcinoma. Due to its substantial antitumor activity, tolerance (at the recommended MTD level), and convenient 3-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.

RESUMEN

The majority of lymphomas of the mucosa-associated lymphoid tissue (MALT)-type arise in the stomach, but extragastric locations are also frequently encountered. Due to previous results indicating that somatostatin receptor (SSTR)-expression distinguishes between gastric and extragastric MALT-type lymphoma, we have initiated a study to evaluate the role of SSTR-scintigraphy for staging and follow-up of patients with extragastric manifestations of MALT-type lymphoma. A total of 30 consecutive patients, including 24 with primary extragastric MALT-type lymphoma, 5 patients with dissemination to extragastric sites (including colon, lung, parotid, ocular adnexa and breast) following an initial gastric MALT-lymphoma and one patient with spread to stomach, lung and lymph nodes following parotid lymphoma were prospectively studied. All patients had histologically verified MALT-type lymphoma: 2 patients had lymphoma presenting in the lung, 9 in the ocular adnexa, 7 had lymphomas in the parotid, 2 patients had disease located in the breast, 3 patients had lymph-node relapse following MALT-type lymphoma of the parotid, the lacrimal gland and the thyroid, and 1 had primary MALT-lymphoma of the liver. All patients underwent SSTR-scintigraphy using (111)In-DTPA-D-Phe(1)-Octreotide ((111)In-OCT) before initiation of therapy, while 13 also had a second scan after treatment. The results of gamma camera imaging were compared to conventional staging. No positive scans could be obtained in patients with dissemination following gastric lymphoma, while all patients with primary extragastric lymphoma had positive scans at the site of histologically documented involvement before initiation of therapy. In addition, also the patient with secondary spread to stomach, lung and lymph nodes was positive in all documented lymphoma sites. In one patient, focal tracer uptake in projection to the maxillary sinus was documented, which was bioptically verified as inflammation. In the scans performed after therapy, focal tracer accumulation in the left orbit indicated persistence of disease following irradiation in one patient with otherwise negative work-up, which was verified by MRI and biopsy 6 months later. In another patient, a positive scan indicated disease relapse in the lacrimal gland 9 months before clinical verification by means of ultrasound. In one patient, a focus not present in the pretherapeutic scan was found in the ethmoidal sinus, corresponding to a hyperplastic polyp. Both SST-scan as well as CT indicated disease persistence in one case, while negative scans corresponding to complete remission as judged by conventional staging were obtained following therapy in the remaining patients, and absence of relapse has been confirmed for a median follow-up of 2 years. These results indicate that (111)In-OCT is an excellent tool for staging and non-invasive therapy-monitoring in extragastric MALT-type lymphomas. These data further confirm our initial finding that gastric MALT-type lymphomas do not express relevant amounts of respective SSTR, and that SSTR-scanning is able to distinguish between gastric vs extragastric origin of MALT-type lymphoma irrespective of the site of presentation.

RESUMEN

BACKGROUND: To evaluate the efficacy and tolerance of combined raltitrexed and oxaliplatin in patients with advanced colorectal cancer pretreated with fluoropyrimidine leucovorin-based chemotherapy. PATIENTS AND METHODS: Thirty-six patients with metastatic colorectal cancer, who progressed while receiving or within six months after withholding palliative chemotherapy with fluoropyrimidines leucovorin +/- irinotecan, participated in this study. Treatment consisted of oxaliplatin 130 mg/m2 and raltitrexed 3.0 mg/m2 both given on day 1 every three weeks for a total of eight courses unless prior evidence of progressive disease. RESULTS: The overall objective response rate was 33.3% for all 36 evaluable patients (95% confidence interval (CI): 18.6%-51%). Seventeen additional patients (47.2%) had stable disease, and only seven (19.5%) progressed. The median progression-free survival was 6.5 months (range 1.2-14.0). After a median follow-up time of 12 months, 23 patients (63.8%) are still alive. The tolerance of treatment was acceptable with only 8 of 36 patients (22%) experiencing grade 3 or 4 neutropenia. Grade 3 non-haematological adverse reactions included peripheral sensory neuropathy in three, asthenia in one, diarrhea in two, and clinically insignificant increase in serum transaminases in two patients, respectively. CONCLUSIONS: Our data suggest that the combination of oxaliplatin and raltitrexed has substantial antitumour activity in patients with progressive fluoropyrimidine leucovorin + irinotecan pretreated colorectal cancer. Because of its favorable toxicity profile and convenient three-weekly outpatient administration schedule, further evaluation of this regimen seems warranted.

RESUMEN

BACKGROUND: Patients with advanced biliary tract carcinoma face a dismal prognosis as no effective palliative therapy has been defined. The aim of the present phase II investigation was to evaluate the therapeutic efficacy and tolerance of a two-weekly high-dose gemcitabine regimen in this patient population. PATIENTS AND METHODS: Thirty-two consecutive patients with locally unresectable or metastatic biliary tract cancer were enrolled in this multicenter phase II trial. Treatment consisted of gemcitabine 2200 mg/m2 given as a 30-min intravenous infusion every two weeks for a duration of six months unless there was prior evidence of progressive disease. RESULTS: After a median number of 12 treatment courses, 7 of 32 (22%) patients had a partial response that lasted for a median duration of 6.0 months (range 3.5-10.0). Fourteen additional patients (44%) had stable disease, whereas eleven patients (34%) progressed despite therapy. The median time to progression was 5.6 months (range 1.8-13.0); median survival time was 11.5 months (range 3.0-24.0), and the probability of surviving beyond 12 months was 44%. The tolerance of treatment was remarkable with only two patients each experiencing grade 3 leukocytopenia, granulocytopenia and/or thrombocytopenia, and one patient had grade 3 anaemia. Similarly, nonhaematologic side effects were infrequent, and generally mild to moderate. CONCLUSIONS: Two-weekly high-dose gemcitabine seems to represent a potentially effective, safe and well-tolerated regimen for the palliative treatment of patients with advanced biliary tract cancer.
