Khorana score and thromboembolic risk in stage II-III colorectal cancer patients: a post hoc analysis from the adjuvant TOSCA trial.

BACKGROUND: The risk of venous thromboembolic events (VTE) during adjuvant chemotherapy for colorectal cancer (CRC) is unknown. We aim to evaluate if the Khorana score (KS) can predict this risk, and if it represents a prognostic factor for overall survival (OS) through a post hoc analysis of the phase III TOSCA trial of different durations (3- versus 6-months) of adjuvant chemotherapy. METHODS: A logistic regression model was used to test the associations between the risk of VTE and the KS. The results are expressed as odds ratios (OR) with 95% confidence intervals (95% CI). To assess the effect of the KS on OS, multivariable analyses using Cox regression models were performed. The results are expressed as hazard ratios (HR) with 95% CI. RESULTS: Among 1380 CRC patients with available data, the VTE risk (n = 72 events: 5.2%) was similar in the two duration arms (5.5% versus 4.9%), with 0.2% of patients belonging to the high-risk KS group. Rates of VTE were similar in the low- and intermediate-risk groups (4.8% versus 6.4%). KS did not represent an independent predictive factor for VTE occurrence. Chemotherapy duration was not associated with VTE risk. In addition, KS was not prognostic for OS in multivariate analysis (HR: 0.92, 95% CI, 0.63-1.36; p = 0.6835). CONCLUSIONS: The use of the KS did not predict VTEs in a low-moderate thromboembolic risk population as CRC. These data did not support the use of KS to predict VTE during adjuvant chemotherapy, and suggest that other risk assessment models should be researched.

The Path of Cicely Saunders: The "Peculiar Beauty" of Palliative Care.

This paper is aimed at focusing on the writings and the experience of the Hospice movement Founder, Dame Cicely Saunders. The in-depth analysis carried out had the objective of verifying if "the way" of Cicely to understand, live and propose palliative care was still current and "beautiful", so that we can nowadays refer to her fascinating "Original Palliative Care". With "beauty" we mean, on the one hand, a way able to allow a personal path of research of the meaning of the disease and of the care, both for those who care and for those who are cared for. On the other hand, it seems to us that Cicely strongly suggests how this path can not be carried out alone, but is only possible within the context of a network of relationships and support, in a so called "relational autonomy", for the patient, included in a "care ethics". The authors believe that the work extensively documents as the overall approach of Cicely, traditional but always to be rediscovered, is still today the most convincing way of conception and action of palliative care.

Gait abnormalities in people with Dravet syndrome: A cross-sectional multi-center study.

OBJECTIVE: To quantify gait abnormalities in people with Dravet syndrome (DS). METHODS: Individuals with a confirmed diagnosis of DS were enrolled, and stratified according to knee flexion at initial contact (IC) and range of motion (ROM) during stance (atypical crouch: knee flexion >20° at IC and knee ROM >15° during stance; straight: knee flexion <20° at IC). A 1D ANOVA (α = 0.05) was used to test statistical differences among the joint kinematics and spatio-temporal parameters of the cohort and an age-matched control group. Clinical (neurological and orthopaedic evaluation) and anamnestic data (seizure type, drugs, genetic mutation) were collected; distribution between the two gait phenotypes was assessed with the Fisher exact test and, for mutation, with the chi-squared test (p < 0.05). Linear regression between maximum knee flexion and normalised walking speed was calculated. RESULTS: Seventy-one subjects were enrolled and evaluated with instrumented gait analysis. Fifty-two were included in final analysis (mean age 13.8 ± 7.3; M 26). Two gait patterns were detected: an atypical crouch gait (34.6%) with increased ankle, knee and hip flexion during stance, and reduced walking speed and stride length not associated with muscle-tendon retractions; and a pattern resembling those of healthy age-matched controls, but still showing reduced walking speed and stride length. No differences in clinical or anamnestic data emerged between the two groups. SIGNIFICANCE: Objectively quantified gait in DS shows two gait patterns with no clear-cut relation to clinical data. Kinematics abnormalities may be related to stabilization issues. These findings may guide rehabilitative and preventive measures.

Dravet syndrome: Early electroclinical findings and long-term outcome in adolescents and adults.

To describe the outcome of Dravet syndrome (DS) in adolescents and adults we conducted a longitudinal retrospective study of two independent cohorts of 34 adolescents (group 1) and 50 adults (group 2). In both cohorts, we collected information about genetic mutation, and semiology of seizures at onset and during disease course. At the last evaluation, we considered the following features: epilepsy (distinguishing myoclonic/complete and nonmyoclonic/incomplete phenotype), neurologic signs, intellectual disability (ID), and behavioral disorders. Moreover, in both cohorts, we performed a correlation analysis between early characteristics of the disease and the outcome of DS with regard to seizure persistence, ID, behavioral disorder, and neurologic impairment at last evaluation. Group 1 includes 22 adolescents with complete form of DS and 12 with incomplete form; group 2 includes 35 adults with complete form and 15 with incomplete form. The seizures persisted in 73.6% of adolescents and in 80% of adults, but epilepsy severity progressively decreased through age. Seizure persistence correlated with the complete phenotype and with the occurrence of reflex seizures. At last evaluation, ID was moderate or severe in 70.5% of adolescents and in 80% of adults. The most severe cognitive and motor impairment was observed in patients with persisting seizures. The severity of cognition, language, and neurologic impairment at last evaluation correlated statistically with the complete phenotype. The study confirms that the global outcome of DS is poor in most cases, albeit epilepsy severity decreases throughout adulthood. The improvement of epilepsy throughout ages is not associated with improvement in intellectual abilities and motor skills; this confirms that the unfavorable outcome is not a pure consequence of epilepsy.

A multicenter, randomized, phase 3 trial comparing fixed dose versus toxicity-adjusted dose of cisplatin + etoposide in extensive small-cell lung cancer (SCLC) patients: The Small-cell-lung cancer Toxicity Adjusted Dosing (STAD-1) trial.

OBJECTIVES: Data supporting the prognostic role of chemotherapy induced haematological toxicity suggest that toxicity-adjusted-dosing (TAD) of chemotherapy might improve treatment efficacy. We tested whether TAD of the cisplatin-etoposide combination might improve the response rate, in previously untreated extensive stage disease (ED)-SCLC patients, as compared with standard fixed-dosing (FD). METHODS: Patients with ED-SCLC were randomized to receive either TAD or FD of cisplatin-etoposide as first-line treatment. Primary endpoint was the objective response rate (ORR) according to the RECIST 1.0 criteria, secondary endpoints included progression free survival (PFS), overall survival (OS) and toxicity. RESULTS: Hundred-fifty-eight patients were randomized. Most patients were male, with ECOG-PS 1, without brain metastases and had not received radiotherapy before study entry. Response rate was 54.4 (95%CI: 43.5-64.9%) and 58.2 (95%CI: 47.2-68.5%) in the control and experimental arms, respectively (P=0.75). No significant differences were found in terms of PFS (HR 1.04; 95%CI: 0.74-1.44, P=0.84) and OS (HR1.01; 95%CI 0.71-1.42, p=0.97). Seven patients died on treatment, one in the standard arm and 6 in the experimental arm. The most frequent cause of death was neutropenia with infection and, apart in one, death was not related to dose modification. Severe toxicity was more frequent in the experimental arm (91% vs 60%). CONCLUSIONS: In our population of chemonaïve ED SCLC patients, TAD failed to improve the ORR, PFS and OS over the FD of cisplatin-etoposide as first line chemotherapy and was associated with increased toxicity.

Movement-activated cortical myoclonus in Dravet syndrome.

PURPOSE: we characterized multifocal myoclonus in Dravet syndrome (DS) that was never systematically typified before. METHODS: we studied EEG-EMG recordings of 19 consecutive patients, aged 2-29 years, with DS associated with SCN1A gene mutations to detect and evaluate myoclonus based on the spectrum of EMG activity on antagonist muscle pairs and cortico-muscular coherence (CMC). RESULTS: multifocal action myoclonus was detected in all patients corresponding to brief EMG bursts, which occurred synchronously on antagonist muscles at a frequency peaking in beta band. There was significant CMC in beta band, and a cortico-muscular transfer time consistent with a cortical origin of the jerks. The somatosensory evoked potentials (SSEPs) were giant in only one patient who also showed exaggerated long-loop reflexes (LLRs). The nine patients who had experienced myoclonic seizures showed greater CMC. CONCLUSIONS: The cortical myoclonus consistently observed in patients with DS shows features that are similar to those characterizing progressive myoclonus epilepsy, but differs because it does not have a severely worsening course and is not commonly associated with increased SSEPs or enhanced LLRs. This kind of myoclonus is an intrinsic feature of DS associated with SCN1A mutations, and may be a cause of disability. SIGNIFICANCE: We hypothesize that myoclonus is generated in cortical motor areas by hyper-synchronous oscillations, which are possibly due to sodium channel dysfunction.

Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) as second-line chemotherapy in HER2-negative, taxane-pretreated metastatic breast cancer patients: prospective evaluation of activity, safety, and quality of life.

BACKGROUND: A prospective, multicenter trial was undertaken to assess the activity, safety, and quality of life of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) as second-line chemotherapy in HER2-negative, taxane-pretreated metastatic breast cancer (MBC). PATIENTS AND METHODS: Fifty-two women with HER2-negative MBC who were candidates for second-line chemotherapy for the metastatic disease were enrolled and treated at three centers in Northern Italy. All patients had previously received taxane-based chemotherapy in the adjuvant or first-line metastatic setting. Single-agent nab-paclitaxel was given at the dose of 260 mg/m(2) as a 30-minute intravenous infusion on day 1 each treatment cycle, which lasted 3 weeks, in the outpatient setting. No steroid or antihistamine premedication was provided. Treatment was stopped for documented disease progression, unacceptable toxicity, or patient refusal. RESULTS: All of the enrolled patients were evaluable for the study endpoints. The objective response rate was 48% (95% CI, 31.5%-61.3%) and included complete responses from 13.5%. Disease stabilization was obtained in 19 patients and lasted >6 months in 15 of them; the overall clinical benefit rate was 77%. The median time to response was 70 days (range 52-86 days). The median progression-free survival time was 8.9 months (95% CI, 8.0-11.6 months, range 5-21+ months). The median overall survival point has not yet been reached. Toxicities were expected and manageable with good patient compliance and preserved quality of life in patients given long-term treatment. CONCLUSION: Our results showed that single-agent nab-paclitaxel 260 mg/m(2) every 3 weeks is an effective and well tolerated regimen as second-line chemotherapy in HER2-negative, taxane-pretreated MBC patients, and that it produced interesting values of objective response rate and progression-free survival without the concern of significant toxicity. Specifically, the present study shows that such a regimen is a valid therapeutic option for that 'difficult to treat' patient population represented by women who at the time of disease relapse have already received the most active agents in the adjuvant and/or metastatic setting (ie, conventional taxanes).

Spinal muscular atrophy associated with progressive myoclonic epilepsy: A rare condition caused by mutations in ASAH1.

OBJECTIVE: To present the clinical features and the results of laboratory investigations in three patients with spinal muscular atrophy associated with progressive myoclonic epilepsy (SMA-PME), a rare condition caused by mutations in the N-acylsphingosine amidohydrosilase 1 (ASAH1) gene. METHODS: The patients were submitted to clinical evaluation, neurophysiologic investigations (that included wakefulness and sleep electroencephalography [EEG], video-polygraphic recording with jerk-locked back-averaging, multimodal evoked potentials, and electromyography), brain magnetic resonance imaging (MRI), biochemical screening, muscle and skin biopsies, and molecular genetic analysis. RESULTS: The main clinical features were onset in childhood with proximal muscular weakness, generalized epilepsy with absences and myoclonic seizures, cognitive impairment of variable degree; the course was progressive with muscle wasting and uncontrolled epileptic seizures. In one patient, earlier onset before the age of 2 years was associated with a more complex clinical picture, with abnormal eye movements, progressive cognitive impairment, and a more rapid and severe course. EEG/polygraphic data were consistent with PME, demonstrating generalized spike-and-wave discharges, evidence of positive and negative myoclonia, and prominent photosensitivity. In one patient, transcranial magnetic stimulation showed a hyperexcitable motor cortex, whereas somatosensory evoked potentials were unaffected. Possible involvement of the central acoustic and visual pathways was suggested by abnormal auditory and visual evoked potentials. Muscle biopsies showed typical signs of neurogenic damage. Molecular genetic analysis showed mutations of the ASAH1 gene. SIGNIFICANCE: Our data indicate that SMA-PME associated with ASAH1 mutations is a genetically distinct condition with specific clinical and neurophysiologic features. Further studies are warranted to explore the role of the ASAH1 gene in muscle and brain function.

Dravet phenotype in a subject with a der(4)t(4;8)(p16.3;p23.3) without the involvement of the LETM1 gene.

We present a patient affected by Dravet syndrome. Thorough analysis of genes that might be involved in the pathogenesis of such phenotype with both conventional and next generation sequencing resulted negative, therefore she was investigated by a-GCH that showed the presence of an unbalanced translocation resulting in a der(4)t(4;8)(p16.3,p23.3). This was an unconventional translocation, different from the recurrent translocation affiliated with WHS and did not involve LETM1.

Chemotherapy-induced anemia and oncologist perception on treatment: results of a web-based survey.

AIMS AND BACKGROUND: Anemia prevalence and incidence in chemotherapy-treated patients is high. Erythropoiesis-stimulating agents (ESAs) are frequently employed in the management of chemotherapy-induced anemia. However, other treatments such as red blood transfusion or iron supplementation are normally used. Recent international guidelines raised some concern about ESAs employment with a possible impact in chemotherapy-induced anemia management and changes in clinical practice behavior. METHODS: To evaluate opinions about chemotherapy-induced anemia clinical management preference, the Associazione Italiana Oncologia Medica (AIOM) Lombardy section coordinators sent via email a 12-item questionnaire about their knowledge on CIA and usual therapeutic strategies to manage this adverse event to AIOM Lombardy onco-hematologist members. RESULTS: From January 2011 to March 2011, 81 questionnaires were collected with an approximated share of 30%. The survey was completed mainly by oncologists (91%) aged 35-50 years (50%). Chemotherapy-induced anemia was considered to have clinical impact in changing cancer therapeutic strategy by nearly 60% of the respondents. ESAs were administered largely (80%) with concomitant iron supplementation in 52%; 38% jointly used blood transfusion as part of the therapy. Nearly 20% of those who replied correctly employed transferrin saturation levels as a marker to guide iron supplementation. Physician prescribers strictly followed the guidelines to start and stop ESAs even if 14% were negatively influenced by new ASCO recommendations. ESA biosimilars were considered future substitutes of originators in 45% of the cases. CONCLUSIONS: Chemotherapy-induced anemia was perceived as an adverse event with a mild impact on clinical practice. ESAs were largely employed, however the number of transfusions and lack of employment of markers of iron depletion suggested that adherence to guidelines could be theoretically met but with some discordances regarding the most appropriate strategies in daily clinical practice.

Encephalopathy with status epilepticus during sleep or continuous spikes and waves during slow sleep syndrome: a multicenter, long-term follow-up study of 117 patients.

PURPOSE: To retrospectively analyze the electroclinical features, etiology, treatment and prognosis of 117 patients with encephalopathy with status epilepticus during sleep (ESES) or continuous spike and waves slow sleep (CSWSS) syndrome with a long-term follow-up. METHODS: Charts of 117 patients with ESES/CSWSS syndrome followed between 1990 and 2012 were analyzed. Inclusion criteria were: (1) focal seizures or apparently generalized seizures and focal EEG epileptiform discharges; (2) further occurrence of atypical absences, and myoclonic, atonic, and/or generalized seizures; (3) cognitive impairment and/or behavior disturbances; (4) continuous spike-and-wave discharges during slow sleep in more than 85% of non-REM sleep. Patients with spike-and-wave discharges in less than 85% of slow sleep were also analyzed. KEY FINDINGS: 'Mean follow-up from onset of ESES/CSWSS was 13 years (range, 2-22 years) in the symptomatic/structural and non-idiopathic group consisting of 79 children and 10.5 years (range, 2-21 years) in the idiopathic group consisting of 38 children. The comparison of clinical findings and localization of paroxysmal EEG abnormalities (focal, multifocal, or generalized) at the different stages (before, during, and after ESES/CSWSS) and the percentage of spike-wave index during ESES/CSWSS between the symptomatic/structural and non-idiopathic and the idiopathic group was not statistically significant. SIGNIFICANCE: ESES/CSWSS syndrome is an epileptic encephalopathy with similar electroclinical findings in children with a >85% spike-wave index and those with a <85% spike-wave index. In this series of patients, the most commonly used treatments were clobazam, ethosuximide, sulthiame, alone or in combination. In refractory cases, high-dose steroids were administered. Among the AED responders, the idiopathic cases returned to normality and the structural cases returned to baseline cognitive development.

Prognostic impact of education level of patients with advanced non-small cell lung cancer enrolled in clinical trials.

BACKGROUND: Socioeconomic status can potentially affect prognosis of cancer patients. Our aim was to describe potential differences in demographic and clinical characteristics, treatment, and survival by education level in patients with advanced non-small cell lung cancer (NSCLC) enrolled in clinical trials of first-line treatment. METHODS: Individual data of Italian patients with advanced NSCLC (stage IV, or IIIB with supraclavicular nodes or malignant pleural effusion), ECOG performance status (PS) 0-2, enrolled in four phase III randomized trials conducted between 1996 and 2005 were pooled. Information about education was available for 1680 of 1709 patients (98.3%). Patients were divided in two groups according to education level: high (patients with at least high school diploma) or low (those with less than high school diploma). Survival analyses were stratified by treatment arm within trial. RESULTS: There were 312 (19%) and 1368 (81%) patients with high and low education, respectively. Education level was significantly different among birth cohorts, with a time-trend toward higher education level. Patients with high education were significantly younger (median age 65 vs. 70), were less frequently unfit at diagnosis (ECOG PS2 5% vs. 16%), and their tumor type was more frequently adenocarcinoma (47% vs. 37%). Number of treatment cycles received was not significantly different between education groups. Median survival was 9.4 and 7.6 months in high and low education, respectively (p=0.012). At multivariable analysis, female sex, better PS and high education level (Hazard Ratio 0.85, 95%CI 0.73-0.99, p=0.03) were independently associated with longer survival. CONCLUSIONS: In Italian patients enrolled in four randomized trials of first-line chemotherapy for advanced NSCLC, high education was significantly more frequent among younger patients, and was associated with lower proportion of PS2 patients. Education level did not significantly affect number of chemotherapy cycles received. Overall survival was longer in patients with high education, after adjustment for PS and other prognostic factors. The exact underlying mechanisms of the independent prognostic role of education level are substantially unknown, but lead-time bias (anticipation in diagnosis and time to inclusion in the trial), differences in adherence to care outside the trial procedures, differences in comorbidities and life-style factors may all contribute.

Medical treatment choices for patients affected by advanced NSCLC in routine clinical practice: results from the Italian observational "SUN" (Survey on the lUng cancer maNagement) study.

Lung cancer is the most common cancer in the world today, in terms of both incidence and mortality. Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers, and the majority of people diagnosed with NSCLC have locally advanced or metastatic disease. Treatment algorithms have rapidly changed in the last 10 years because of the introduction of new chemotherapeutic and targeted agents in clinical practice. SUN is a 1-year longitudinal observational multicenter study that has consecutively enrolled patients affected by stage IIIB or IV NSCLC with the aim to describe the pattern of care and evolving approaches in the treatment of advanced NSCLC. 987 consecutive NSCLC patients were enrolled between January 2007 and March 2008 at the 74 participating centers throughout Italy and a 12-month follow-up was performed. Cyto-histological diagnosis was performed mainly by broncoscopy with only 24% by CT-scan guided fine-needle aspiration biopsy. 91.4% of the patients received a first-line medical treatment and 8.6% supportive care only. Median age of patients receiving first-line treatment was 66 years. First-line chemotherapy consisted of a single agent in 20% of patients and combination chemotherapy in 80%. The most frequently used chemotherapy regimens were cisplatin plus gemcitabine and carboplatin plus gemcitabine. Median survival of patients receiving first-line chemotherapy was 9.1 months. 32% percent of patients received a second-line treatment that consisted of chemotherapy in 71% of cases and erlotinib in 29%. Overall third-line treatment was given to 7.3% of patients. These results showed a pattern of care for advanced NSCLC that reflects the current clinical practice in Italy at the study time with a high adherence to the International guidelines by the Italian Oncologists.

Palonosetron in combination with 1-day versus 3-day dexamethasone for prevention of nausea and vomiting following moderately emetogenic chemotherapy: a randomized, multicenter, phase III trial.

PURPOSE: A phase III trial assessed the efficacy of palonosetron plus dexamethasone given once in preventing acute and delayed chemotherapy-induced nausea and vomiting (CINV) following a broad range of moderately emetogenic chemotherapy (MEC) regimens. METHODS: This multicentre, randomized, open-label, non-inferiority trial evaluated two different treatment groups. One group received palonosetron (0.25 mg intravenously) and dexamethasone (8 mg intravenously) before chemotherapy, while the other was administered the same regimen on day 1 followed by dexamethasone 8 mg orally on days 2 and 3. The primary endpoint was complete response (CR; defined as no emetic episodes and no rescue medication) during the overall phase (days 1-5 after chemotherapy initiation). The non-inferiority margin was predefined as a 15% difference between groups in the primary endpoint. RESULTS: Of 332 chemotherapy-naïve patients included in the intention-to-treat analysis, 65.1% were female, and 35.2% received anthracycline plus cyclophosphamide (AC)-based regimens. Overall CR rates were 67.5% for those administered dexamethasone only on day 1 (n = 166), and 71.1% for those also administered dexamethasone on days 2 and 3 (n = 166; difference -3.6% (95% confidence interval, -13.5 to 6.3)). CR rates were not significantly different between groups during the acute (0-24 h post-chemotherapy; 88.6% versus 84.3%; P = 0.262) and delayed phases (days 2-5; 68.7% versus 77.7%; P = 0.116). CONCLUSIONS: Palonosetron plus single-dose dexamethasone administered before common MEC regimens provide protection against acute and delayed CINV which is non-inferior to that of palonosetron plus dexamethasone for 3 days. However, the major benefit of the single-day regimen occurs in patients receiving non-AC MEC regimens.

Randomized phase III trial of gemcitabine plus cisplatin compared with single-agent gemcitabine as first-line treatment of patients with advanced pancreatic cancer: the GIP-1 study.

PURPOSE: Single-agent gemcitabine became standard first-line treatment for advanced pancreatic cancer after demonstration of superiority compared with fluorouracil. The Gruppo Italiano Pancreas 1 randomized phase III trial aimed to compare gemcitabine plus cisplatin versus gemcitabine alone (ClinicalTrials.gov ID NCT00813696). PATIENTS AND METHODS: Patients with locally advanced or metastatic pancreatic cancer, age 18 to 75 years, and Karnofsky performance status (KPS) > or = 50, were randomly assigned to receive gemcitabine (arm A) or gemcitabine plus cisplatin (arm B). Arm A: gemcitabine 1,000 mg/m(2) weekly for 7 weeks, and, after a 1-week rest, on days 1, 8, and 15 every 4 weeks. Arm B: cisplatin 25 mg/m(2) added weekly to gemcitabine, except cycle 1 day 22. Primary end point was overall survival. To have 8% power of detecting a 0.74 hazard ratio (HR) of death, with bilateral alpha .05, 355 events were needed and 400 patients planned. RESULTS: Four hundred patients were enrolled (arm A: 199; arm B: 201). Median age was 63, 59% were male, 84% had stage IV, and 83% had KPS > or = 80. Median overall survival was 8.3 months versus 7.2 months in arm A and B, respectively (HR, 1.10; 95% CI, 0.89 to 1.35; P = .38). Median progression-free survival was 3.9 months versus 3.8 months in arm A and B, respectively (HR, 0.97; 95% CI, 0.80 to 1.19; P = .80). The objective response rate was 10.1% in A and 12.9% in B (P = .37). Clinical benefit was experienced by 23.0% in A and 15.1% in B (P = .057). Combination therapy produced more hematologic toxicity, without relevant differences in nonhematologic toxicity. CONCLUSION: The addition of weekly cisplatin to gemcitabine failed to demonstrate any improvement as first-line treatment of advanced pancreatic cancer.

A case of bullous dermatitis induced by erlotinib.

Herein, we report a case of bullous dermatitis that occurred in a 61-year-old woman 5 days after beginning therapy with erlotinib for the treatment of stage IV pulmonary adenocarcinoma with metastases at the hypophyseal level. Skin reactions are the most common adverse drug reactions (ADRs) associated with epidermal growth factor receptor tyrosine kinase (EGFR-TK) inhibitors, and acneiform rash is the most frequently reported ADR in patients treated with erlotinib. To our knowledge, this is the first case of bullous dermatitis induced by erlotinib. This report highlights the need for additional research in the field of skin toxicity of EGFR-TK inhibitors.

Evidence of autonomic dysregulation in otherwise healthy cancer caregivers: a possible link with health hazard.

Caregiving, an important component of cancer patient treatment, may set forth a cascade of stress responses such as sympatho-adrenal activation, immuno-humoral changes and an unhealthy lifestyle, which could be hazardous to caregivers' health. In this observational study, we addressed whether autonomic nervous system (ANS) regulation and perception of stress would be altered in a group of 58 health cancer caregivers as compared to 60 controls. We employed non invasive autoregressive spectral analysis of cardiovascular variabilities and ad hoc questionnaires. Caregivers show, in addition to signs of psychological involvement, a clear autonomic imbalance, suggestive of sympathetic predominance at rest and of a reduction of vagal cardiac regulation (overall gain of baroreflex -index alpha- was respectively of 17.5+/-1.5 versus 25.1+/-1.8 msec/mmHg, p<<0.02). These data suggest possible preventive strategies, based on tailored treatments aiming at a betterment of individual autonomic profile.

The MILES-2G phase 2 study of single-agent gemcitabine with prolonged constant infusion in advanced non-small cell lung cancer elderly patients.

BACKGROUND: Gemcitabine has been widely studied in elderly patients affected by advanced non-small cell lung cancer (NSCLC). A prolonged constant infusion (10 mg/m2/min) has been proposed as a way to improve its efficacy. Aim of this study is to describe activity and toxicity of single-agent gemcitabine given as prolonged infusion in the treatment of elderly patients with advanced NSCLC. PATIENTS AND METHODS: Patients aged 70 years or older, with stage IV or IIIB (effusion/supraclavicular nodes) NSCLC, good performance status (0 or 1 according to ECOG classification) who had never received chemotherapy were eligible. Gemcitabine was administered at the dose of 1200 mg/m2 by prolonged infusion (10 mg/m2/min) on days 1 and 8 of each cycle. Courses were repeated every 21 days, for a maximum of 6 cycles, unless disease progression or severe toxicity. A single stage phase 2 design was applied, with 51 patients required to estimate a 25% +/- 10% response rate. Ten responses were required to define the treatment as active. RESULTS: Fifty-one patients were enrolled, with a median age of 76 years (range 70-83). Two complete responses and seven partial responses were observed, for an overall response rate of 17.6% (95% exact C.I.: 8.4-30.9%). The median time to disease progression was 16.1 weeks (95% C.I.: 11.1-20.6) and the median overall survival was 41.3 weeks (95% C.I.: 27.6-50.6). There were 2 toxic deaths, due to bleeding and liver toxicity, and one patient had an ischemic stroke. Other non-haematological toxicities were: fatigue (44% of patients), grade 2-3 pulmonary toxicity (8%), grade 2-3 hepatic toxicity (16%). Nausea and stomatitis were mild and no cases of cardiac toxicity were observed. Haematological toxicity was mild, with no case of febrile neutropenia. CONCLUSION: Gemcitabine at prolonged constant infusion produced a response rate lower than that required by study design and should no longer be of interest for the treatment of elderly patients with advanced NSCLC.

Adjuvant treatment of high-risk, radically resected gastric cancer patients with 5-fluorouracil, leucovorin, cisplatin, and epidoxorubicin in a randomized controlled trial.

BACKGROUND: Promising findings obtained using a weekly regimen of 5-fluorouracil (5-FU), epidoxorubicin, leucovorin (LV), and cisplatin (PELFw) to treat locally advanced and metastatic gastric cancer prompted the Italian Group for the Study of Digestive Tract Cancer (GISCAD) to investigate the efficacy of this regimen as adjuvant treatment for high-risk radically resected gastric cancer patients. METHODS: From January 1998 to January 2003, 400 gastric cancer patients at high risk for recurrence including patients with serosal invasion (stage pT3 N0) and/or lymph node metastasis (stage pT2 or pT3 N1, N2, or N3), were enrolled in a trial of adjuvant chemotherapies; 201 patients were randomly assigned to receive the PELFw regimen, consisting of eight weekly administrations of cisplatin (40 mg/m2), LV (250 mg/m2), epidoxorubicin (35 mg/m2), 5-FU (500 mg/m2), and glutathione (1.5 g/m2) with the support of filgrastim, and 196 patients were assigned to a regimen consisting of six monthly administrations of a 5-day course of 5-FU (375 mg/m2 daily) and LV (20 mg/m2 daily, 5-FU/LV). Disease-free and overall survival were estimated and compared between arms using hazard ratios (HRs) and Kaplan-Meier estimates. All statistical tests were two-sided. RESULTS: The 5-year survival rates were 52% in the PELFw arm and 50% in the 5-FU/LV arm. Compared with the 5-FU/LV regimen, the PELFw regimen did not reduce the risk of death (HR = 0.95, 95% confidence interval [CI] = 0.70 to 1.29) or relapse (HR = 0.98, 95% CI = 0.75 to 1.29). Less than 10% of patients in either arm experienced a grade 3 or 4 toxic episode. Neutropenia (occurring more often in the PELFw arm) and diarrhea and mucositis (more prevalent in the 5-FU/LV arm) were the most common serious side effects. Nevertheless, only 19 patients (9.4%) completed the treatment in the PELFw arm and 85 (43%) patients completed the treatment in the 5-FU/LV arm. CONCLUSIONS: Our study found no benefit from an intensive weekly chemotherapy in gastric cancer. The extent of toxicity experienced by the patients in the adjuvant setting suggests that, in gastric cancer, chemotherapy may be more safely administered preoperatively.

Avaliação do tratamento medicamentoso ambulatorial em pacientes hipertensos / Ambulatory treatment evaluation in patients with hypertension

Objetivo: Descrever os aspectos relativos à terapêutica da hipertensão em pacientes atendidos no Ambulatório de Especialidades Médicas - UNISUL entre março de 2003 a abril de 2005. Método: Estudo observacional com delineamento tipo coorte. A amostra foi constituída por 165 adultos, portadores de hipertensão e que realizaram 2 consultas com intervalo de pelo menos 2 meses. O instrumento de coleta de dados foi o protocolo de pesquisa. Foi realizada a aferição da pressão arterial (PA) na 13 e 23 consultas e anotadas as terapêuticas medicamentosas realizadas. PA de 140/90 mmHg foi considerada controlada O IMC, a presença de tabagismo e de medicações predisponentes de hipertensão também foram avaliados. Resultados: A média de idade foi 50,1 anos. A maioria dos pacientes referiu nunca ter fumado. A média do IMC foi 32,1. Na 13 consulta, a PA sistólica teve como média 152,7 mmHg e a diastólica 94,lmmHg. Já na 23 consulta, a média da PA sistólica foi de 139,4mmHg e da diastólica 87,6mmHg. Não houve diferença estatisticamente significativa ao relacionar a PA sistólica e diastólica médias na 13 e 23 consultas em relação ao sexo. Terapia prévia à 13 consulta foi observada em 81 % dos pacientes, na maioria mulheres. Mono e dupla terapias foram as mais freqüentes em ambos os sexos. IECA e Diurético foram os medicamentos mais utilizados. O controle da PA foi alcançado em 49,7% dos pacientes. A dislipidemia e a diabete melito foram as doenças associadas à HAS mais prevalentes. Observou-se que a maioria das doenças, com exceção do acidente vascular cerebral e da insuficiência renal, foram mais freqüentes nas mulheres. A prevalência da diabete melito e da insuficiência coronariana foram iguais em ambos os sexos. Os AINEs e os antidepressivos foram os medicamentos predisponentes de HAS mais freqüentemente utilizados pelas mulheres. Os homens utilizaram mais os corticosteróides...
