The safety and activity of immune checkpoint inhibitors have been characterized in interventional and observational studies. However, only small studies have specifically investigated these agents in patients who are excluded or underrepresented in clinical trials, frequently referred to as “special populations” or “underrepresented populations.” These include older adults, those with dysregulated immune activation, patients with a compromised immune function, and those carrying major viral infections, lymphoproliferative diseases, and major organ dysfunctions. Therefore, there remains substantial uncertainty regarding the use of immune checkpoint inhibitors in these specific settings. The Network of Italian Supportive Care in Oncology has carried out a multidisciplinary project, with the contribution of oncologists and other specialists, to retrieve the existing evidence on the use of immunotherapy in patients with solid and hematological cancers with the final aim to provide an expert guidance. The results of this effort are presented in this article, which is focused on patients with major viral infections or those with immune dysregulation/autoimmune diseases, and could be useful to guide decisions in clinical practice and to design prospective clinical trials focusing on the use of immunotherapy in these populations.

Nab-P is widely used in MBC, but limited data from clinical practice are available. This is an open-label, multicentre prospective cohort study prospectively collecting data of MBC pts treated with weekly, or every 3 week administration of Nab-P. For this survey a convenience sample was used. An attempt was made to get at least a sample of 200 pts, which guarantees a standard error of 3.5% for estimation of survival time at 1 year, overall response rate and grade 3-4 toxicity. Overall response rate was 32.1% in the whole population, without any significant difference according to schedule, previous paclitaxel exposure, presence of visceral metastases or line of treatment. Median time to progression was 6 months (95% confidence interval, 1-34), with no differences according to the schedule of treatment. No new data on toxicity were reported. Results from this real life experience suggest that Nab-P can be safely used with both the weekly and the 3-weekly schedule with comparable efficacy, leaving the choice to the physician according to the patient's needs and preference, with a carefully balance between activity and potential toxicity. Background Few data are available regarding efficacy and safety of nanoparticle albumin-bound (nab)-paclitaxel in advanced breast cancer patients outside a controlled trial, especially for the weekly schedule. Patients and Methods We prospectively collected data of advanced breast cancer patients who were candidates to be treated with weekly (125 mg/m2 for 3 consecutive weeks followed by a 1-week rest) or every 3 weeks (260 mg/m2) schedules of nab-paclitaxel, according to physician's decision. Results The study enrolled 209 patients, of whom 92 (39.3%) received weekly nab-paclitaxel. The median age was 58 (range, 31-84) years; 21.8% of the patients were classified as triple-negative breast cancer (estrogen-recetor/progesteron-receptor-negative). The median number of cycles was 5.5. The overall response rate was 32.1% in the whole popu

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 regardin
