COVID-19 vaccination in cancer patients: Immune responses one year after the third dose

Cancer patients (CPs), being immunosuppressed due to the treatment received or to the disease itself, are more susceptible to infections and their potential complications, showing therefore an increased risk of developing severe COVID-19 compared to the general population. We evaluated the immune responses to anti-SARS-CoV-2 vaccination in patients with solid tumors one year after the administration of the third dose and the effect of cancer treatment on vaccine immunogenicity was assessed. Healthy donors (HDs) were enrolled. Binding and neutralizing antibody (Ab) titers were evaluated using chemiluminescence immunoassay (CLIA) and Plaque Reduction Neutralization Test (PRNT) respectively. T-cell response was analyzed using multiparametric flow cytometry. CPs who were administered three vaccine doses showed lower Ab titers than CPs with four doses and HDs. Overall, a lower cell-mediated response was found in CPs, with a predominance of monofunctional T-cells producing TNFα. Lower Ab titers and a weaker T-cell response were observed in CPs without prior SARS-CoV-2 infection when compared to those with a previous infection. While no differences in the humoral response were found comparing immunotherapy and non-immunotherapy patients, a stronger T-cell response in CPs treated with immunotherapy was observed. Our results emphasize the need of booster doses in cancer patients to achieve a level of protection similar to that observed in healthy donors and underlines the importance of considering the treatment received to reach a proper immune response.

Antinuclear antibodies may predict the development of immune-related adverse events in asymptomatic patients treated with immune checkpoint inhibitors: results from a single-center cohort

We aim at investigating the association between subclinical autoimmunity and immune-related adverse events (irAEs) in a cohort of patients treated by immune checkpoint inhibitors for solid metastatic cancer. In the context of an oncology/rheumatology outpatient clinic, we evaluated patients treated with anti-PD-1 or anti-PD-L1. Before treatment, each patient underwent a physical evaluation and a blood sample to identify the presence of a set of autoantibodies. Indeed, all the patients were followed during treatment to identify irAEs and to assess the association with autoantibodies. Fifty-one patients (M/F 16/35; median age 70 years, IQR 16.5) were evaluated; 34.8% of patients showed ANA positivity, 6.5% ENA positivity (anti-SSA), 4.3% Ratest positivity, and 2.1% (one patient) ACPA positivity. During a median period of 21 months (IQR 38.75), 39.2% of patients developed irAEs. Musculo-skeletal manifestations, in particular arthritis, were the most frequent. We found a significant association between the positivity for ANA and the development of irAES (p = 0.03, RR 2.01, 95% CI 1.03-3.92). Furthermore, the progression-free survival was significantly longer in patients developing irAEs compared to those who are not experiencing these events (p = 0.007). This study underlines the potential role of ANA positivity as a predictive biomarker for the development of irAEs.

Comparison of Long-Term Effectiveness and Safety of Upadacitinib for Atopic Dermatitis Between Dupilumab-Exposed and Dupilumab-Naïve Patients

BACKGROUND AND OBJECTIVES

Upadacitinib is an oral selective Janus kinase-1 inhibitor approved for the treatment of moderate-to-severe atopic dermatitis (AD) in patients [Formula: see text] 12 years of age. In real life, upadacitinib currently represents a valid therapeutic option for patients failing available systemic therapies, in particular patients who discontinued dupilumab because of lack of efficacy or occurrence of adverse events. The objectives of the present study were to compare the effectiveness and safety of upadacitinib in patients affected by AD who had previously failed dupilumab therapy versus biologic naïve patients.

METHODS

A retrospective, multi-centre, observational, real-life study was conducted in four Italian dermatological referral centres (Milan, Perugia, Naples and Vicenza). Baseline characteristics included age, sex, AD history and severity, prior treatments, comorbidities and concomitant therapies. AD severity was assessed at baseline and at week 4 (W4), W16, W24 and W52, using Eczema Area Severity Index (EASI), Dermatology Life Quality Index (DLQI) and Pruritus Numerical Rating Scale (P-NRS) scores. Full blood count, hepatic and renal function, lipid panel, and muscle enzymes [lactate dehydrogenase (LDH) and creatine phosphokinase (CPK)] were assessed at baseline and at each follow-up visit.

RESULTS

A total of 113 patients (72 males, 63.7%; mean age: 37.22 ± 16.8 years) were included in the analysis, all patients were in treatment and underwent follow-up period until W16, whilst 91 (80.5%) and 75 (66.4%) patients were in treatment and in follow-up period until W24 and W52, respectively. Mean EASI score significantly changed from 24.30 ± 10.27 to 1.28 ± 4.34, 0.74 ± 2.31 and 0.25 ± 1.34 at W16, W24 and W52, respectively (p < 0.0001). Specifically, at W16 the percentage of patients achieving EASI-75, EASI-90 and EASI-100 was 85.21, 76.35 and 66.11%, respectively. At W24, EASI-75, EASI-90 and EASI-100 were reached by 88.54, 85.42, and 78.37% of patients, respectively. Finally, 90.1% of patients achieved EASI-75, 88.3% achieved EASI-90 and 83.0% achieved EASI-100 at W52.

CONCLUSIONS

This study confirmed the clinical effectiveness of upadacitinib treatment in adult patients in a real-world setting with moderate-to-severe AD who had discontinued dupilumab due to poor effectiveness or adverse events and who were biologic naïve; therefore, previous treatments do not seem to affect the response to upadacitinib treatment.

A 52-week multicenter retrospective real-world study on effectiveness and safety of dupilumab in children with atopic dermatitis aged from 6 to 11 years

Background: Dupilumab has been shown to be a safe and effective drug for the treatment of atopic dermatitis (AD) in children from 6 months to 11 years in randomized clinical trials. Aim: The aim of this real-life study was to determine the effectiveness in disease control and safety of dupilumab at W52 in moderate-to-severe AD children aged 6-11 years.Methods: All data were collected from 36 Italian dermatological or paediatric referral centres. Dupilumab was administered at label dosage with an induction dose of 300 mg on day 1 (D1), followed by 300 mg on D15 and 300 mg every 4 weeks (Q4W). Treatment effect was determined as overall disease severity, using EASI, P-NRS, S-NRS and c-DLQI at baseline, W16, W24, and W52. Ninety-six AD children diagnosed with moderate-to-severe AD and treated with dupilumab were enrolled.Results: Ninety-one (94.8%) patients completed the 52-week treatment period and were included in the study. A significant improvement in EASI score, P-NRS, S-NRS and c-DLQI was observed from baseline to weeks 16, 24 and 52.Conclusions: Our real-life data seem to confirm dupilumab effectiveness and safety in paediatric patients. Moreover, our experience highlighted that patients achieving clinical improvement at W16 preserved this condition over time.

A Rare Type of Radiation-Induced Alopecia: Proton-Induced Alopecia

Introduction

Radiation-induced alopecia (RIA) is a side effect resulting from cranial radiation therapy (RT) and it can be temporary or permanent. In cancer patients, RIA is a less frequent event than chemotherapy-induced alopecia, although the former is more likely to cause permanent hair loss. It is characterized initially by intense anagen effluvium caused by acute dose-dependent damage to the matrix cells of anagen follicles. Proton therapy (PT) is a specific type of RT used in the treatment of brain tumors, which sometimes can cause proton-induced alopecia (PIA), a rare subtype of RIA. Below, we report a case of a patient who presented PIA following PT treatment of a meningioma of the frontal region.

Case Presentation

A 38-year-old female patient presented to our trichology outpatient clinic for widespread hair loss in the frontal region. Following a diagnosis of meningioma of the frontal region 3 years ago, adjuvant radiotherapy treatment of the frontal region with scanning beam PT (mean dose of 45 Gy) was performed. Two weeks after the end of treatment, the patient came to our attention with diffuse hair loss at the level of the PT-treated area. Trichoscopy showed flame hairs, broken hairs, black dots, and pigtail hairs. A diagnosis of PIA was established, and topical treatment with minoxidil 5% solution twice a day was initiated. At the follow-up visit after 4 months, the patient had total hair regrowth.

Conclusion

PIA is a subtype of RIA still poorly studied in the literature. Hair loss is caused by aggression by radiations of the hair follicle in the anagen phase, leading to an interruption of the mitotic activity of the matrix cells. The cells of the follicular bulb are characterized by marked mitotic activity at this stage and are consequently more susceptible to cytotoxic damage. All this causes tightening of the proximal portion of the hair shaft, increasing its fragility and susceptibility to breakage.

An overview of new and emerging antibody therapies for moderate-severe atopic dermatitis in adults

INTRODUCTION

A comprehensive review of the English-language medical literature was performed searching for ongoing and closed clinical trials concerning new and emerging monoclonal antibody therapies for moderate-to-severe atopic dermatitis in adults.

AREAS COVERED

Atopic dermatitis is a chronic inflammatory cutaneous disease with a complex pathogenesis. In the last years, numerous advances in understanding the atopic dermatitis pathogenesis allowed to obtain several therapeutic options, such as numerous monoclonal antibodies. Some monoclonal antibodies, such as dupilumab (anti-IL-4 Rα) and tralokinumab (anti-IL13) are already approved for the treatment of moderate-to-severe atopic dermatitis, and numerous articles in the literature have demonstrated their efficacy and safety. As there are numerous drugs under investigation, this review focuses on emerging monoclonal antibody therapies.

EXPERT OPINION

There are numerous monoclonal antibodies under investigation that may be approved in the near future for the treatment of atopic dermatitis. Data from phase 2b and phase III clinical trials in moderate-to-severe atopic dermatitis in adults indicate that these drugs have a promising efficacy and safety profile. Monoclonal antibodies currently under investigation will be available in the coming years to enrich the therapeutic choice of new alternatives that are valid both in terms of efficacy and safety.

The Management of Oligometastatic Disease in Colorectal Cancer: Present Strategies and Future Perspectives

Oligometastatic disease has been described as an intermediate clinical state between localized cancer and systemically metastasized disease. Recent clinical studies have shown prolonged survival when aggressive locoregional approaches are added to systemic therapies in patients with oligometastases. The aim of this review is to outline the newest options to treat oligometastatic colorectal cancer (CRC), also considering its molecular patterns. We present an overview of the available local treatment strategies, including surgical procedures, stereotactic body radiation therapy (SBRT), thermal ablation, as well as trans-arterial chemoembolization (TACE) and selective internal radiotherapy (SIRT). Moreover, since imaging methods provide crucial information for the early diagnosis and management of oligometastatic CRC, we discuss the role of modern radiologic techniques in selecting patients that are amenable to potentially curative locoregional treatments.

Rheumatic Diseases Development in Patients Treated by Anti-PD1 Immune Checkpoint Inhibitors: A Single-Centre Descriptive Study

The introduction of the so-called immune checkpoint inhibitors (ICIs) substantially changed the history of cancer therapy. On the other hand, they can induce the development of rheumatic immune-related adverse events (Rh-irAEs). In the scenario of a joint oncology/rheumatology outpatient clinic, we conducted a single-centre descriptive study to define from a laboratory, clinical and therapeutic point of view, rheumatic conditions developed during anti-PD1 treatment. The study included 32 patients (M/F 16/16, median age 69, IQR 16.5). According to the international classification criteria, eight patients could be classified as affected by Rheumatoid Arthritis, one by Psoriatic Arthritis, six by Polymyalgia Rheumatica, five by systemic connective tissue diseases (two systemic lupus erythematosus, two Sjögren’s syndrome, one undifferentiated connective tissue disease). The remaining patients were diagnosed as having undifferentiated arthritis or inflammatory arthralgia. The median interval between ICIs starting and the onset of symptoms was 14 weeks (IQR 19.75). Moving to treatment, the longitudinal observation revealed that all RA, PsA and CTD patients required the introduction of treatment with DMARDs. In conclusion, the growing use of ICIs in a real-life setting confirmed the possible development of different rheumatological conditions, further emphasising the need for shared oncology/rheumatology management.

Efficacy and safety of biologics and small molecules for psoriasis in pediatric and geriatric populations. Part I: focus on pediatric patients

INTRODUCTION

Psoriasis management is challenging, especially in pediatric age for different factors. The introduction of biologic drugs and oral small molecules (OSM) revolutionized the armamentarium of available weapons in psoriasis treatment. Despite the use of these drugs in adult patients has been widely investigated, pediatric patients have often been unconsidered in clinical trials and real-life studies. However, the high efficacy and speed of action, the safety profile and the ease-to-use administration make these innovative drugs an invaluable therapeutic opportunity.

AREAS COVERED

The aim of this manuscript is to perform a review of the current literature examining data on the effectiveness and safety of biologic drugs and OSM for the management of psoriasis in pediatric patients in order to put the basis for universally shared treatment algorithm following available evidence. PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines were used for the literature research.

EXPERT OPINION/COMMENTARY

Our review based on currently available evidence suggests biologics and OSM as an ideal treatment option for pediatric patients, with an excellent profile in terms of efficacy and safety as compared to traditional systemic drugs.

Efficacy and safety of biologics and small molecules for psoriasis in pediatric and geriatric populations. Part II: focus on elderly patients

INTRODUCTION

The management of moderate-to-severe forms of psoriasis is becoming a frequent concern in geriatric age due to the higher risk to develop treatment adverse events, logistic issues, vulnerability to immune-related diseases and cancer, presence of comorbidities and the risk of drug interactions. In this context, traditional systemic treatments are often contraindicated, and biologic drugs and small molecules seem to be a valuable option. However, data on their effectiveness and safety in elderly patients are scant.

AREAS COVERED

The aim of this review is to analyze the current literature in order to point out data on the efficacy and safety of biologic drugs and small molecules for the management of psoriasis in elderly patients in order to put the basis for universally shared treatment algorithm following available evidence. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used for the literature research.

EXPERT OPINION/COMMENTARY

Our review suggests biologics and small molecules as an effective and safe option for the management of moderate-to-severe forms of psoriasis in elderly patients.

Injections Site Reactions and Biologics for Psoriasis: A Questionnaire Based Real Life Study

Background

Biologic selection for psoriasis treatment should take into account numerous factors including injection site reactions (ISRs) such as swelling at the injection site, pain, burning, erythema, all possibly reducing patient adherence.

Methods

A 6-months observational real life study was performed involving psoriasis patients. Inclusion criteria were age ≥ 18 years, moderate-to-severe psoriasis diagnosis since at least 1 year, patients being on biologic treatment for psoriasis ≥ 6 months. A 14-item questionnaire was administered to all patients enrolled to assess whether the patient ever experienced ISRs after the injection of the biologic drug.

Results

234 patients were included: 32.5% received an anti-TNF-alpha drug, 9.4% received anti-IL12/23, 32.5% received an anti-IL17, 25.6% received an anti-IL23. 51.2% of study population reported at least one symptom related to ISR. 35.9% of patients experienced pain, 31.6% swelling, 28.2% burning sensation and 17.9% erythema. 3.4% of the surveyed population experienced anxiety or fear of the biologic injection due to ISRs symptoms. The greater incidence of pain was registered in anti-TNF-alpha and anti-IL17 groups (47.4% and 42.1%, p<0.01). Ixekizumab proved to be the drug with the highest rate of patients experiencing pain (72.2%), burning (77.7%) and swelling (83.3%). No patients reported biologics discontinuation or delay for ISRs symptoms.

Conclusion

Our study highlighted that each different class of biologics for psoriasis was linked to ISRs. These events are more frequently reported with anti-TNF-alpha and anti-IL17.

Psoriatic Alopecia and Paradoxical Psoriasis Induced by Adalimumab Successfully Treated with Certolizumab: Clinical, Trichoscopic, and in vivo Reflectance Confocal Microscopy Features

<b><i>Introduction:</i></b> Psoriatic alopecia is considered a type of hair loss occurring in patients with psoriasis. Adalimumab is a fully humanized recombinant anti-TNF-alpha monoclonal antibody approved for treatment of psoriasis and psoriatic arthritis (PsA), rarely related to the occurrence of dermatological disorders. <b><i>Case Presentation:</i></b> We report the case of a 56-year-old female with PsA developing psoriatic alopecia and paradoxical psoriasis induced by adalimumab and successfully treated switching to certolizumab, evaluating response at both thrichoscopy and in vivo reflectance confocal microscopy. <b><i>Discussion:</i></b> Among anti-TNF-α agents, certolizumab is the least involved in the development of paradoxical reactions such as psoriatic alopecia and showed to be an effective and safe alternative therapeutic options to manage psoriasis and PsA minimizing the risk of paradoxical reactions.

Effect of Dupilumab on Sexual Desire in Adult Patients with Moderate to Severe Atopic Dermatitis

Background: Atopic dermatitis (AD) is a chronic inflammatory condition causing itching skin, with a significant psychosocial impact on patients and relatives. AD affects 15 to 30% of children and 2 to 10% of adults. AD significantly affects patients' quality of life (QoL) given the chronicity and symptoms of the disease. Most AD patients have reported that the disease affects daily life, resulting in limited social contact and a strong impact on sexual health (SH), especially in moderate-severe cases. Materials and methods: We performed a prospective study from 1 May 2020 to 1 May 2022; the aim of the study was to evaluate the impact of moderate to severe AD on sexual desire, seduction, and partner relationships, and describe how it varies following dupilumab therapy. We used the Sexual Desire Inventory-2 (SDI-2), a validated instrument consisting of 14 items; moreover, we used a second questionnaire with eight items, an unvalidated instrument created specifically for this study, to obtain the assessment of the influence of AD on the body image, sexuality, and self-perception of those affected. Results and Conclusions: The impact of AD on sexual desire assessed using SDI-2 showed a significant improvement in both sexes during dupilumab treatment from the baseline to W4 and W16. Similar results were obtained with our questionnaire.

Urticaria Relapse after mRNA COVID ‐19 vaccines in patients affected by chronic spontaneous urticaria and treated with antihistamines plus omalizumab: a single‐center experience

Urticaria is a disease characterized by wheals and/or angioedema. Chronic spontaneous urticaria (CSU) occurs for longer than 6 weeks and appears independently of any identifiable exogenous stimulus. During the vaccination campaign for Coronavirus disease 2019 (COVID‐19) pandemic, several cutaneous adverse events have been described, among which urticaria lasting less than 6 weeks (acute urticaria, AU). AU due to vaccines can be IgE or non‐IgE mediated; the former typically develop within 4 h of drug exposure, the latter occurs later and the mechanism is unclear. In this retrospective study we analyzed the frequency and clinical characteristics of urticaria occurring after COVID‐19 vaccine (post‐vaccination urticaria relapse) in adult CSU patients treated with antihistamine and omalizumab, and in clinical remission.

Guselkumab, Risankizumab, and Tildrakizumab in the Management of Psoriasis: A Review of the Real-World Evidence

Interleukin (IL)-23 inhibitors, guselkumab, risankizumab, and tildrakizumab, represent the latest class of biologics approved for the treatment of moderate-to-severe psoriasis. Since their approval numerous real-life studies were published on anti-IL-23 use in routine clinical practice. Indeed, real-life data are important to improve the dermatological decision-making process, including patients who are typically excluded from clinical trials, such as subjects suffering from several comorbidities, subjects on polypharmacy, as well as multifailure patients. Herein, we performed a comprehensive literature review about real-life data available on guselkumab, risankizumab, and tildrakizumab. Real-life data of anti-IL-23 seem to confirm the promising results of IL-23 shown by clinical trials, highlighting the efficacy and safety profiles of this new class of biologics also in clinical practice.

Dupilumab for the treatment of adult atopic dermatitis in special populations

BACKGROUND

Special populations (SPs) involve people who require additional consideration in clinical research. Effectiveness of treatment or occurrence of side effects may be different in SPs with respect to not-SPs.

OBJECTIVES

To retrospectively compare the effectiveness and safety of dupilumab in AD treatment of SPs versus not-SPs.

METHODS

A 52-weeks retrospective study was performed enrolling patients with a diagnosis of moderate-to-severe AD undergoing treatment with dupilumab at labelled dosage. Patients were divided in Group A (SPs patients) and Group B (not-SPs patients). Disease severity was assessed using Eczema Area Severity Index (EASI), Pruritus-Numerical Rating Scale (P-NRS), and Dermatology Life Quality Index (DLQI) score at baseline and after 4 weeks (W4), W16, W24, and W52.

RESULTS

A total of 263 patients were enrolled and divided in Group A (25) and Group B (238). SPs included history of cancer, severe kidney failure, viral hepatitis, neurological diseases, acquired immunodeficiency syndrome, and transplanted patients. A statistically significant reduction of EASI, DLQI, and P-NRS was assessed in both groups at each follow-up visit (p < 0.0001), without significant differences between the groups. No differences were recorded for safety.

CONCLUSIONS

There are not significant differences between SPs and not-SPs as regards effectiveness and safety of dupilumab in AD management.

A Case of New-Onset Lichen Planus after COVID-19 Vaccination

The COVID 19 vaccination campaign has been underway for about a year now, and there are now many skin reactions associated with the administration of these vaccines in the literature. In view of the forthcoming third dose, we believe it is important to report our experience.

Intensified Total Neoadjuvant Therapy Versus Intensified Concurrent Chemoradiotherapy in Locally Advanced Rectal Cancer: A Propensity Score Matching Analysis

BACKGROUND/AIM

To compare clinical outcomes following intensified total neoadjuvant therapy (TNT) and intensified neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC).

PATIENTS AND METHODS

Of the 79 patients with LARC admitted to our department, 51 received intensified neoadjuvant CRT (CRT group) and 28 received intensified TNT (TNT group). Intensified TNT was defined as multi-agent chemotherapy, including FOLFOXIRI regimen plus bevacizumab (mutated Ras-BRAF) or panitumumab/cetuximab (wild-type Ras-BRAF) followed by oxaliplatin-5-fluorouracil-based CRT and surgery. Kaplan-Meier and Log rank test were used for survival analysis. Survival rates of the two groups were compared using propensity score matching.

RESULTS

Data from 28 TNT patients and 28 CRT patients were analyzed after a 1:1 propensity matching with replacement. Kaplan-Meier curve showed that overall survival (OS), disease-free survival (DFS) and distant metastasis-free survival (DMFS) rates with TNT were comparable to those with CRT. The 5-year DMFS rates for TNT and CRT were 61.5% versus 63.0% (p=0.82), respectively. In the TNT group, 32.1% patients (n=9) achieved pathological complete response (pCR), whereas 21.4% patients (n=6) achieved pCR with CRT (p=0.37).

CONCLUSION

Intensified TNT and CRT resulted in similar survival outcomes, while intensified TNT led to higher pCR, albeit not statistically significant.

Onset of vitiligo in a psoriasis patient on ixekizumab

INTRODUCTION

Vitiligo is an acquired skin disorder clinically characterized by hypopigmentated macules and patches. Psoriasis is a chronic-inflammatory-skin-condition characterized by erythematous-plaques covered with scales particularly over the extensor-surfaces, scalp, and lumbosacral region. Recent major-researches-advancements have significantly expanded our understanding of psoriasis-pathophysiology, resulting in the development of highly effective targeted-therapies, such as anti TNFα, IL-12/23-inhibitors, IL-17-inhibitors, or IL-23-inhibitors. Particularly, ixekizumab, a humanized-monoclonal immunoglobulin-G 4 antibody, specifically binding IL-17A, demonstrated strong efficacy in threating recalcitrant psoriasis. Nevertheless, paradoxical reactions due to IL-17 inhibitors have been described.

CASE REPORT

Herein, we report the case of a 53-year-old Caucasian man who obtained complete skin clearance of psoriasis plaques after 16 weeks of ixekizumab treatment together with the appearance of vitiligo patches localized on the facial area. He had never suffered of vitiligo and his family history excluded vitiligo diagnosis. We also could exclude post inflammatory psoriasis hypopigmentation because of absence of facial involvement at baseline. Our experience suggests that vitiligo might be considered a rare adverse effects of anti-IL-17 therapy.

Weekly Vinorelbine and Docetaxel as Second-Line Chemotherapy for Pretreated Non-Small Cell Lung Cancer Patients: a Phase I-II Trial

Docetaxel was proven to be effective as second-line therapy for patients with advanced NSCLC after failure of platinum-based front-line chemotherapy. We designed this phase I/II study to define the Maximum Tolerated Dose of weekly docetaxel combined with weekly vinorelbine, and subsequently evaluate tolerability and activity of this schedule in NSCLC patients who were progressive after treatment with either cisplatin and gemcitabine or carboplatin and paclitaxel regimens. To be eligible for the study, patients were required to have a WHO performance status < or =2, failure after at least two cycles of first platinum-based chemotherapy, and no prior treatment with docetaxel and vinorelbine. A total of 27 patients were enrolled in this phase I/II study. A weekly docetaxel dose of 25 mg/m2 was recommended in combination with fixed vinorelbine dose of 20 mg/m2, and 24 patients were treated at this dose level. Severe neutropenia (62%) and febrile neutropenia (29%) were the most frequent toxicities, with 83% of patients requiring dose modification or delay. In the phase II study, 5 (21%) patients obtained a partial response, 8 (33%) patients had stable disease, whereas 10 (42%) patients progressed. After a median follow-up of 18.7 months, median survival was 8 months, with 30% surviving at 1 year. Regardless of the use of weekly docetaxel schedule, this regimen was highly myelosuppressive, and did not seem to improve response rate and survival compared to single-agent docetaxel. No further developments of this schedule are warranted.

Combined cardiohepatic transplantation due to severe heterozygous familiar hypercholesteremia type II: first case in Argentina--a case report

Heterozygous familial hypercholesteremia type II is a recessive autonomic disease with a population incidence <or=1:500. It develops as a consequence of a mutation in the LDLR gene. Patients suffer extremely high LDL and VLDL cholesterol values, dying from coronary compromise at early ages. As cholesterol synthesis is an hepatic process, and as there is a lack of gene therapy, hepatic transplantation is the only therapeutic option in cases refractory to medical treatment. In this report, we have described the first case of combined cardiohepatic transplantation in Argentina, which was performed in a male patient with severe aortic stenosis and terminal ischemic cardiopathy secondary to severe familial hypercholesteremia type II.

Phase II study of sequential chemotherapy with cisplatin (P) in combination with infusional 5FU/LV (PFL) followed by irinotecan (Ir) + 5FU/LV (IrFL) followed by docetaxel (T) + 5FU/LV (TFL) in patients (pts) with metastatic gastric carcinoma (MGC) by the Gruppo Oncologio Nord-Ovest (GONO)

15059

Background: 5FU in combination with P can be considered a standard treatment for MGC. Ir and T are active agents with not complete cross-resistance with P and 5FU. The combination of Ir or T with P and 5FU is feasible but with substantial toxicities. A different way to include Ir and T in the first-line treatment of MGC is to use them sequentially to a P and 5FU containing regimen. Methods: we conducted a phase II study of first-line sequential chemotherapy in MGC pts with measurable disease (RECIST criteria). Treatment consisted of: 3 cycles of PFL (biweekly P 50 mg/sqm d1, LV 200 mg/sqm d1 and 5FU 3200 mg/sqm 48-h c.i. starting on d1) followed by 3 cycles of IrFL (biweekly Ir 180 mg/sqm d1 and 5FU/LV) followed by 3 cycles of TFL (biweekly T 50 mg/sqm d1 and 5FU/LV). Evaluation of disease was performed every 3 cycles. Results: 46 pts have been enrolled. Pts characteristics are: median age = 60 years (37–75), M/F = 36/10, sites of disease (single/multiple) 9/37, ECOG PS 0/1 = 27/19. Treatment was well tolerated. Grade 3–4 non-haematological toxicities were: diarrhea in 2,5% pts with PFL; diarrhea and asthenia in 2,5% and stomatitis in 5% pts with IrFL; stomatitis in 5,7% pts with TFL. Grade 3/4 neutropenia was observed in 14% pts with PFL, 15% with IrFL and 22,9% pts with TFL. Nor febrile neutropenia neither toxic deaths have occurred. Two pts had not evaluable disease and 6 are still receiving treatment. We observed 1 CR and 8 PR with PFL (RR 24%) among the 38 evaluable pts. IrFL improved responses in 10 pts while 4 pts progressed and TFL further improved responses in 6 pts while 5 pts progressed. Response rate at the end of the planned 9 cycles was 40% (4 CR, 11 PR; 95% CI 25–58%). At a median follow-up of 15.5 mos median TTP is 6.8 mos and median OS is 13.5 mos. Conclusions: this sequential treatment is feasible with a very favourable safety profile and produces encouraging results in terms of activity and efficacy in a population of unselected MGC patients. Final data will be presented at the meeting. Partially supported by A.R.C.O. Foundation.
