    الوصف: The fight against doping in sport is internationally coordinated by the World Anti-Doping Agency (WADA). Through its World Anti-Doping Code, WADA aims to harmonize anti-doping policies, rules and regulations. One key reference document bound to the Code is the International Standard for Laboratories (ISL), which mainly specifies the criteria that must be met for laboratory accreditation, as well as standards to adopt for the production of valid test results and evidentiary data. Within the ISL, the Code of Ethics refers to the Helsinki Declaration as a guiding framework for anti-doping research. However, inasmuch as anti-doping research structurally differs from human subject research as considered by the Helsinki Declaration, the applicability of the latter to anti-doping research can be called into question. In this work, we discuss how key principles of the Helsinki Declaration apply to anti-doping research and highlight frictions, incompatibilities and misalignments. Furthermore, we indicate possible solutions for operationalizing the Helsinki principles within the context of anti-doping research.

    الوصف: Background: Little progress has been made, and there is an unmet medical need for treatment of metastatic gastric cancer (MGC). Docetaxel + cisplatin + 5-fluororacil (DCF) combination is an effective regimen with high rate of toxicity and is not well tolerated. We aimed to evaluate the efficacy and toxicity of a modified DCF (mDCF) combination regimen and capecitabine maintenance in MGC. Method: Data of MGC patients were treated with first-line mDCF regimen (two weekly docetaxel 60 mg/m2 day 1 iv, cisplatin 50 mg/m2 day 1 iv, 5-fluouracil 400 mg/m2 day 1 iv push, 2400 mg/m2; day 1–day 2 iv infusion, leucovorin 400 mg/m2 day 1 iv push) were recorded. Capecitabine maintenance was given as 2500 mg/m2/ day 1–day 14 po, every 3 weeks, to patients who do not have progressive disease and grade 3 treatment-related toxicity. A retrospective analysis was made. Results: Forty patients were included. Mean age was 53 ± 11. Thirty-two patients had de novo metastasis. All patients’ performance status was ECOG 1 or 2 (32/8). Median number of mDCF cycles given was 9 (min–max: 1–23). Overall response rate was 47.5%. Ten patients (25%) received capecitabine maintenance. Grade 3/4 toxicity was seen in 20 patients (50%). Hematologic grade 3/4 toxicity occurred in 13 patients (32.5%), and grade 3/4 neutropenia occurred in 11 patients (27.5%) and in 15 cycles. Nonhematologic grade 3/4 toxicity was seen in 7 patients (17.5%). Median follow-up time was 17.2 months. Median time to progression (TTP) was 10.8 ± 1.9 months (95% CI: 6.89–14.64). Median overall survival was 14.7 ± 1.73 months (95% CI: 11.30–18.10). Conclusions: mDCF protocol was a tolerable chemotherapy regimen for the first-line treatment of MGC with higher ORR and longer TTP compared to standard DCF protocol. Capecitabine maintenance might increase TTP. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    الوصف: Patients with advanced hepatocellular carcinoma (HCC) have historically had few options and faced extremely poor prognoses if their disease progressed after standard-of-care tyrosine kinase inhibitors (TKIs). Recently, the standard of care for HCC has been transformed as a combination of the immune checkpoint inhibitor (ICI) atezolizumab plus the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab was shown to offer improved overall survival in the first-line setting. Immunotherapy has demonstrated safety and efficacy in later lines of therapy as well, and ongoing trials are investigating novel combinations of ICIs and TKIs, in addition to interventions earlier in the course of disease or in combination with liver-directed therapies. Because HCC usually develops against a background of cirrhosis, immunotherapy for liver tumors is complex and oncologists need to account for both immunological and hepatological considerations when developing a treatment plan for their patients. To provide guidance to the oncology community on important concerns for the immunotherapeutic care of HCC, the Society for Immunotherapy of Cancer (SITC) convened a multidisciplinary panel of experts to develop a clinical practice guideline (CPG). The expert panel drew on the published literature as well as their clinical experience to develop recommendations for healthcare professionals on these important aspects of immunotherapeutic treatment for HCC, including diagnosis and staging, treatment planning, immune-related adverse events (irAEs), and patient quality of life (QOL) considerations. The evidence- and consensus-based recommendations in this CPG are intended to give guidance to cancer care providers treating patients with HCC.

    الوصف: We are witnessing a silent revolution in the treatment of early stage non-small cell lung cancer (NSCLC), with a series of practice-changing clinical trials enriching the therapeutic perspectives of lung cancer patients with potentially curable disease. The ADAURA study marked the advent of precision medicine and biomarker testing to the early stages setting. The IMPower-010 trial interrupted the negative trend of adjuvant lung cancer immunotherapy, paving the way to the application of immune-checkpoint inhibition in the resected disease. The ITACA trial definitively established no role for tailored adjuvant chemotherapy in NSCLC, while the Lung Art data questioned the efficacy of post-operative radiotherapy for pN2 resected disease. Growing evidence is supporting MRD as effective adjuvant prognostic biomarker to stratify disease's recurrence risk after radical interventions and select best candidates to the adjuvant strategies. This work summarizes the recent major breakthroughs in lung cancer adjuvant treatment, and provides a snapshot of the current real-world scenario, discussing the upcoming challenges and opportunities featuring the clinical management of early stage NSCLC patients.

    الوصف: Introduction: BCOR rearranged sarcomas comprise a group of malignant mesenchymal tumors that until recently were classified as Ewing sarcomas or as undifferentiated round cell sarcomas. The identification of alterations involving BCOR gene such as BCOR-CCNB3, BCOR-MAML3, ZC3H7B-BCOR fusion genes and BCOR internal tandem duplication (ITD) is characteristic for the differential diagnosis of BCOR rearranged sarcomas. Due to the rarity of these tumors there is no consensus or guidelines regarding the optimal therapeutic algorithm, that clinicians should follow. Patients and methods: Herein we have conducted a meta-analysis of the current reports dealing with the therapeutic approach of BCOR rearranged sarcomas. Results: Meta-analysis of the 57 eligible cases from 10 studies resulted to similar Incidence Rate Ratio (IRR) and overall survival (OS) for patients who received Ewing protocols and non-Ewing oriented treatment. Further similar death rate was reported for both strategies (non-Ewing 20% Vs Ewing 21.8%). Conclusion: Our data support that non-Ewing treatment strategy can be considered a safe option, being at least equal to Ewing protocols. The current study provides a hint toward the optimal therapeutic approach of BCOR rearranged sarcomas. Further, the present study challenges the use of the term Ewing-like sarcomas, since the current literature supports that BCOR rearranged sarcomas deserve their own distinct classification in terms of genetics, pathology and therapy. © 2021 Acta Oncologica Foundation.

    الوصف: Background The coronavirus disease 2019 (COVID-19) pandemic has overwhelmed the health systems worldwide. Data regarding the impact of COVID-19 on cancer patients (CPs) undergoing or candidate for immune checkpoint inhibitors (ICIs) are lacking. We depicted the practice and adaptations in the management of patients with solid tumors eligible or receiving ICIs during the COVID-19 pandemic, with a special focus on Campania region. Methods This survey (25 questions), promoted by the young section of SCITO (Società Campana di ImmunoTerapia Oncologica) Group, was circulated among Italian young oncologists practicing in regions variously affected by the pandemic: high (group 1), medium (group 2) and low (group 3) prevalence of SARS-CoV-2-positive patients. For Campania region, the physician responders were split into those working in cancer centers (CC), university hospitals (UH) and general hospitals (GH). Percentages of agreement, among High (H) versus Medium (M) and versus Low (L) group for Italy and among CC, UH and GH for Campania region, were compared by using Fisher's exact tests for dichotomous answers and χ 2 test for trends relative to the questions with 3 or more options. Results This is the first Italian study to investigate the COVID-19 impact on cancer immunotherapy, unique in its type and very clear in the results. The COVID-19 pandemic seemed not to affect the standard practice in the prescription and delivery of ICIs in Italy. Telemedicine was widely used. There was high consensus to interrupt immunotherapy in SARS-CoV-2-positive patients and to adopt ICIs with longer schedule interval. The majority of the responders tended not to delay the start of ICIs; there were no changes in supportive treatments, but some of the physicians opted for delaying surgeries (if part of patients' planned treatment approach). The results from responders in Campania did not differ significantly from the national ones. Conclusion Our study highlights the efforts of Italian oncologists to maintain high standards of care ...

    الوصف: BACKGROUND In primary central high-grade osteosarcoma, a number of distinct subtypes have been identified, but little is known about the response to chemotherapy. METHODS The authors investigated whether the subtypes correlated with histologic response to chemotherapy in 1058 patients with osteosarcoma of the extremities who were treated with neoadjuvant chemotherapy over the last 20 years. The tumors were classified as osteoblastic (70%), chondroblastic (13%), fibroblastic (9%), and telangiectatic (6%). At diagnosis, 911 patients had localized disease and 147 had resectable lung metastases. RESULTS The response to preoperative chemotherapy was good (90% or more tumor necrosis) in 59% of patients and poor (< 90% tumor necrosis) in 41% of patients. The rate of good responses was significantly higher (P = 0.0001) in the fibroblastic (83%) and telangiectatic (80%) tumors and significantly lower in chondroblastic tumors (43%). Prognosis was significantly correlated with the histologic subtypes. The 5-year overall survival rate was significantly higher (P = 0.0001) in fibroblastic (83%) and telangiectatic (75%) tumors than in osteoblastic (62%) and chondroblastic (60%) tumors. In all subtypes, except for the chondroblastic subtype, the 5-year overall survival rate was significantly higher (P = 0.0001) in good responders P = 0.0001 (68%) than in poor responders (52%). CONCLUSIONS The authors concluded that the histologic subtype of primary central high-grade osteosarcoma of the extremity was strictly correlated with histologic response to chemotherapy and probably, as a consequence, also with prognosis. Further studies are needed to establish whether these results justify a specific therapeutic approach based on the histologic subtype of the tumor.

    الوصف: WHO classification recognizes grade II astrocytomas, oligodendrogliomas and oligoastrocytomas. Conventional MRI is used for differential diagnosis, guiding surgery, planning radiotherapy and monitoring treatment response. Advanced imaging techniques can increase the diagnostic accuracy. Younger age, normal neurological examination, oligodendroglial histology and 1p loss are favorable prognostic factors. Prophylactic antiepileptic drugs are not useful, whilst there is no evidence that one drug is better than the others. Total/near total resection can improve seizure control, progression-free and overall survival, whilst reducing the risk of malignant transformation. Early post-operative radiotherapy improves progression-free but not overall survival. Low doses of radiation are as effective as high doses and better tolerated. Modern radiotherapy techniques reduce the risk of late cognitive deficits. Chemotherapy can be useful both at recurrence after radiotherapy and as initial treatment after surgery to delay the risk of late neurotoxicity from large-field radiotherapy. Neurocognitive deficits are frequent and can be caused by the tumor itself, tumor-related epilepsy, treatments and psychological distress.
