Global real-world experiences with pembrolizumab in advanced urothelial carcinoma after platinum-based chemotherapy: the ARON-2 study.

BACKGROUND: Immune checkpoint inhibitors have changed previous treatment paradigm of advanced urothelial carcinoma (UC). The ARON-2 study (NCT05290038) aimed to assess the real-world effectiveness of pembrolizumab in patients recurred or progressed after platinum-based chemotherapy. PATIENTS AND METHODS: Medical records of patients with documented metastatic UC treated by pembrolizumab as second-line therapy were retrospectively collected from 88 institutions in 23 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS) and overall response rate (ORR). Cox proportional hazards models were adopted to explore the presence of prognostic factors. RESULTS: In total, 836 patients were included: 544 patients (65%) received pembrolizumab after progression to first-line platinum-based chemotherapy in the metastatic setting (cohort A) and 292 (35%) after recurring within < 12 months since the completion of adjuvant or neoadjuvant chemotherapy (cohort B). The median follow-up time was 15.3 months. The median OS and the ORR were 10.5 months and 31% in the overall study population, 9.1 months and 29% in cohort A and 14.6 months and 37% in cohort B. At multivariate analysis, ECOG-PS ≥ 2, bone metastases, liver metastases and pembrolizumab setting (cohort A vs B) proved to be significantly associated with worst OS and PFS. Stratified by the presence of 0, 1-2 or 3-4 prognostic factors, the median OS was 29.4, 12.5 and 4.1 months (p < 0.001), while the median PFS was 12.2, 6.4 and 2.8 months, respectively (p < 0.001). CONCLUSIONS: Our study confirms that pembrolizumab is effective in the advanced UC real-world context, showing outcome differences between patients recurred or progressed after platinum-based chemotherapy.

The indirect costs of human papillomavirus-related cancer in Central and Eastern Europe: years of life lost and productivity costs.

BACKGROUND: Human papilloma virus (HPV) is a common cause of several types of cancer, including head and neck (oral cavity, pharynx, oropharynx, hypopharynx, nasopharynx, and larynx), cervical, vulval, vaginal, anal, and penile cancers. As HPV vaccines are available, there is potential to prevent HPV-related disease burden and related costs. METHOD: A model was developed for nine Central Eastern European (CEE) countries (Bulgaria, Croatia, Czechia, Hungary, Poland, Romania, Serbia, Slovakia, Slovenia). This model considered cancer patients who died from 11 HPV-related cancers (oropharynx, oral cavity, nasopharynx, hypopharynx, pharynx, anal, larynx, vulval, vaginal, cervical, and penile) in 2019. Due to data limitations, Bulgaria only included four cancer types. The model estimated the number of HPV-related deaths and years of life lost (YLL) based on published HPV-attributable fractions. YLL was adjusted with labor force participation, retirement age and then multiplied by mean annual earnings, discounted at a 3% annual rate to calculate the present value of future lost productivity (PVFLP). RESULTS: In 2019, there were 6,832 deaths attributable to HPV cancers resulting in 107,846 YLL in the nine CEE countries. PVFLP related to HPV cancers was estimated to be €46 M in Romania, €37 M in Poland, €19 M in Hungary, €15 M in Czechia, €12 M in Croatia, €10 M in Serbia, €9 M in Slovakia, €7 M in Bulgaria and €4 M in Slovenia. CONCLUSIONS: There is a high disease burden of HPV-related cancer-related deaths in the CEE region, with a large economic impact to society due to substantial productivity losses. It is critical to implement and reinforce public health measures with the aim to reduce the incidence of HPV-related diseases, and the subsequent premature cancer deaths. Improving HPV screening and increasing vaccination programs, in both male and female populations, could help reduce this burden.

Use of concomitant proton pump inhibitors, statins or metformin in patients treated with pembrolizumab for metastatic urothelial carcinoma: data from the ARON-2 retrospective study.

BACKGROUND: Concomitant medications may potentially affect the outcome of cancer patients. In this sub-analysis of the ARON-2 real-world study (NCT05290038), we aimed to assess the impact of concomitant use of proton pump inhibitors (PPI), statins, or metformin on outcome of patients with metastatic urothelial cancer (mUC) receiving second-line pembrolizumab. METHODS: We collected data from the hospital medical records of patients with mUC treated with pembrolizumab as second-line therapy at 87 institutions from 22 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate. We carried out a survival analysis by a Cox regression model. RESULTS: A total of 802 patients were eligible for this retrospective study; the median follow-up time was 15.3 months. PPI users compared to non-users showed inferior PFS (4.5 vs. 7.2 months, p = 0.002) and OS (8.7 vs. 14.1 months, p < 0.001). Concomitant PPI use remained a significant predictor of PFS and OS after multivariate Cox analysis. The use of statins or metformin was not associated with response or survival. CONCLUSIONS: Our study results suggest a significant prognostic impact of concomitant PPI use in mUC patients receiving pembrolizumab in the real-world context. The mechanism of this interaction warrants further elucidation.

Targeting triple-negative breast cancer: A clinical perspective.

Triple-negative breast cancer (TNBC) is a disease with often an aggressive course and a poor prognosis compared to other subtypes of breast cancer. TNBC accounts for approximately 10%-15% of all diagnosed breast cancer cases and represents a high unmet need in the field. Up to just a few years ago, chemotherapy was the only systemic treatment option for this subtype (1). To date, TNBC is considered a heterogeneous disease. One of the existing classifications is based on the analysis of mRNA expression in 587 TNBC cases, in which Lehman et al. proposed six subtypes of TNBC as follows: two basal-like (BL1 and BL2) subtypes, a mesenchymal (M) subtype, a mesenchymal stem-like (MSL) subtype, an immunomodulatory (IM) subtype, and a luminal androgen receptor (LAR) subtype (2). Later studies have demonstrated that the IM and MSL subtypes do not correlate with independent subtypes but reflect background expression by dense infiltration of tumor-infiltrating lymphocytes (TILs) or stromal cells. According to this finding, the classification of TNBC has been revised into the following four subtypes: basal 1, basal 2, LAR, and mesenchymal subtypes (3). Over the last years, several new strategies have been investigated for the treatment of patients with TNBC. Among them, immunotherapy, antibody drug conjugates, new chemotherapy agents, and targeted therapy have been and are currently being developed. The present article aims to provide an updated overview on the different treatment options that are now available or are still under investigation for patients with TNBC.

Real-world effectiveness of pembrolizumab as first-line therapy for cisplatin-ineligible patients with advanced urothelial carcinoma: the ARON-2 study.

BACKGROUND: The advent of immune-checkpoint inhibitors has challenged previous treatment paradigms for advanced urothelial carcinoma (UC) in the post-platinum setting as well as in the first-line setting for cisplatin-ineligible patients. In this study, we investigated the effectiveness of pembrolizumab as first-line treatment for cisplatin-ineligible UC. METHODS: Data from patients aged ≥ 18 years with cisplatin-ineligible UC and receiving first-line pembrolizumab from January 1st 2017 to September 1st 2022 were collected. Cisplatin ineligibility was defined according to the Galsky criteria. Thirty-three Institutions from 18 countries were involved in the ARON-2 study. RESULTS: Our analysis included 162 patients. The median follow-up time was 18.9 months (95%CI 15.3-76.9). In the overall study population, the median OS was 15.8 months (95%CI 11.3-32.4). The median OS was significantly longer in males versus females while no statistically significant differences were observed between patients aged < 65y versus ≥ 65y and between smokers and non-smokers. According to Recist 1.1 criteria, 26 patients (16%) experienced CR, 32 (20%) PR, 39 (24%) SD and 55 (34%) PD. CONCLUSIONS: Our data confirm the role of pembrolizumab as first-line therapy for cisplatin-unfit patients. Further studies investigating the biological and immunological characteristics of UC patients are warranted in order to optimize the outcome of patients receiving immunotherapy in this setting.

The Role of Isoflavones in the Prevention of Breast Cancer and Prostate Cancer.

This narrative review summarizes epidemiological studies on breast cancer and prostate cancer with an overview of their global incidence distribution to investigate the relationship between these diseases and diet. The biological properties, mechanisms of action, and available data supporting the potential role of isoflavones in the prevention of breast cancer and prostate cancer are discussed. Studies evaluating the effects of isoflavones in tissue cultures of normal and malignant breast and prostate cells, as well as the current body of research regarding the effects of isoflavones attained through multiple modifications of cellular molecular signaling pathways and control of oxidative stress, are summarized. Furthermore, this review compiles literature sources reporting on the following: (1) levels of estrogen in breast and prostate tissue; (2) levels of isoflavones in the normal and malignant tissue of these organs in European and Asian populations; (3) average concentrations of isoflavones in the secretion of these organs (milk and semen). Finally, particular emphasis is placed on studies investigating the effect of isoflavones on tissues via estrogen receptors (ER).

Breast cancer-related mortality in Central and Eastern Europe: years of life lost and productivity costs.

BACKGROUND: Breast cancer (BC) poses a public health challenge as the most commonly diagnosed cancer among women globally. While BC mortality has declined across Europe in the past three decades, an opposite trend has been reported in some transitional European countries. This analysis estimates the mortality burden and the cost of lost productivity due to BC deaths in nine Central and Eastern Europe (CEE) countries: Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania, Serbia, Slovakia, and Slovenia, that have defied the favorable cancer mortality trends. These estimates may provide relevant evidence to aid decision-makers in the prioritization of BC-targeted policies. METHODS: The human capital approach (HCA) was used to estimate years of life lost (YLL) and productivity losses due to premature death from BC (ICD-10 code: C50 Malignant neoplasm of breast). YLL and present value of future lost productivity (PVFLP) were calculated using age and gender-specific mortality, wages, and employment rates. Data were sourced from the World Health Organization (WHO), Eurostat, and the World Bank. RESULTS: In 2019, there were 19,726 BC deaths in the nine CEE countries. This study estimated BC deaths resulted in 267,184 YLL. Annual PVFLP was estimated to be €85 M in Poland, €46 M in Romania, €39 M in Hungary, €21 M in Slovakia, €18 M in Serbia, €16 M in Czech Republic, €15 M in Bulgaria, €13 M in Croatia, and €7 M in Slovenia. CONCLUSION: Premature death from BC leads to substantial YLL and productivity losses. Lost productivity costs due to premature BC-related mortality exceeded €259 million in 2019 alone. The data modeled provide important evidence toward resource allocation priorities for BC prevention, screening, and treatment that could potentially decrease productivity losses. Careful consideration should be given to BC-specific policies, such as surveillance programs and the availability of new treatments in CEE countries to decrease the medical and financial burden of the disease.

Mechanisms of Prostate Cancer Cells Survival and Their Therapeutic Targeting.

Prostate cancer (PCa) is today the second most common cancer in the world, with almost 400,000 deaths annually. Multiple factors are involved in the etiology of PCa, such as older age, genetic mutations, ethnicity, diet, or inflammation. Modern treatment of PCa involves radical surgical treatment or radiation therapy in the stages when the tumor is limited to the prostate. When metastases develop, the standard procedure is androgen deprivation therapy, which aims to reduce the level of circulating testosterone, which is achieved by surgical or medical castration. However, when the level of testosterone decreases to the castration level, the tumor cells adapt to the new conditions through different mechanisms, which enable their unhindered growth and survival, despite the therapy. New knowledge about the biology of the so-called of castration-resistant PCa and the way it adapts to therapy will enable the development of new drugs, whose goal is to prolong the survival of patients with this stage of the disease, which will be discussed in this review.

The Clinical Benefit of Percutaneous Transhepatic Biliary Drainage for Malignant Biliary Tract Obstruction.

Percutaneous transhepatic biliary drainage (PTBD) is a decompression procedure for malignant proximal biliary obstruction. In this research, over a six-year period, 89 patients underwent PTBD procedure for jaundice caused by malignant disease to restart chemotherapy or for palliative intent. Clinical outcomes after PTBD procedure in the two groups of patients, according to the adequate bilirubin decline (ABD) needed for subsequent chemotherapy, are presented in this paper. Survival and logistic regression were plotted and compared using Kaplan−Meier survival multivariate analysis with a long-range test. Results were processed by MEDCALC software. In the series, 58.4% (52/89) of patients were in good performance status (ECOG 0/1), and PTBD was performed with the intention to (re)start chemotherapy. The normalization of the bilirubin level was seen in 23.0% (12/52), but only 15.4% (8/52) received chemotherapy. The median survival time after PTBD was 9 weeks. In patients with ABD that received chemotherapy, the median survival time was 64 weeks, with 30-day mortality of 27.7%, and 6.4% of death within 7 days. The best outcome was in patients with good performance status (ECOG 0−1), low bilirubin (<120 µmol/L) and LDH (<300 µmol/L) levels and elevated leukocytes at the time of the procedures. PTBD is considered in ABD patients who are candidates for chemotherapy.

Progress and pitfalls in the use of immunotherapy for patients with triple negative breast cancer.

INTRODUCTION: Triple negative breast cancer (TNBC) is an area of high unmet medical need in terms of new effective treatment strategies. Although breast cancer is traditionally considered a 'cold' tumor type, TNBC is the most appropriate subtype for immunotherapeutic strategies; this is due to the high level of tumor infiltrating lymphocytes, PD-L1 expression, and tumor mutational burden compared to other breast cancer subtypes. AREAS COVERED: This review examines the available evidence on the use of immunotherapeutic strategies in early and advanced TNBC, discusses the pitfalls and limitations often encountered in clinical research, and summarizes data on novel promising immunomodulatory approaches that have been explored in early-phase trials. EXPERT OPINION: PD-1-blockade is approved for stage II/III TNBC and for first-line treatment of PD-L1-positive TNBC patients with metastatic disease and should be considered standard of care. However, question marks and difficulties remain; these include the identification of predictive biomarkers to select patients who benefit from the addition of PD1-blockade and the balance between efficacy and long-term toxicity for an individual patient. Numerous treatment combinations and new immunotherapeutic strategies beyond PD1 blockade are being evaluated, thus reflecting a promising evolution towards a more personalized approach, and extended clinical benefit in TNBC.Abbreviations:Triple-negative breast cancer (TNBC); breast cancers (BCs); estrogen receptor (ER); progesterone receptor (PgR); human epidermal growth factor-2 (HER-2); basal-like 1 (BL1), basal-like 2 (BL2); mesenchymal (MES); mesenchymal stem-like (MSL); immunomodulatory (IM); luminal androgen receptor (LAR); basal-like immunosuppressed (BLIS); basal-like immune-activated (BLIA); tumor-infiltrating lymphocytes (TILs); tumor mutational burden (TMB); immune cells (ICs); immunohistochemistry (IHC); overall response rate (ORR); overall survival (OS); progression-free survival (PFS); intention-to-treat (ITT); hazard ratio (HR); confidence interval (CI); Food and Drug Administration (FDA); European Medicines Agency (EMA); immune checkpoint inhibitors (ICI); Combined Positive Score (CPS); disease control rate (DCR); neoadjuvant chemotherapy (NACT); pathological complete response (pCR); event-free survival (EFS); disease-free survival (DFS); residual cancer burden (RCB); San Antonio Breast Cancer Symposium (SABCS); antibody-drug conjugates (ADCs); PARP inhibitors (PARPi); clinical benefit rate (CBR); Histone deacetylase inhibitors (HDACi); Dendritic cell (DC); talimogene laherparepvec (TVEC); granulocyte-macrophage colony-stimulating factor (GM-CSF); mismatch repair deficiency (dMMR).

Immunotherapy: A new standard in the treatment of metastatic clear cell renal cell carcinoma.

Renal cell cancer (RCC) represents 2%-3% of all adulthood cancers and is the most common malignant neoplasm of the kidney (90%). In the mid-nineties of the last century, the standard of treatment for patients with metastatic RCC was cytokines. Sunititib and pazopanib were registered in 2007 and 2009, respectively, and have since been the standard first-line treatment for metastatic clear cell RCC (mccRCC). Renal cell cancer is a highly immunogenic tumor with tumor infiltrating cells, including CD8+ T lymphocytes, dendritic cells, natural killer cells (NK) and macrophages. This observation led to the design of new clinical trials in which patients were treated with immunotherapy. With the growing evidence that proangiogenic factors can have immunomodulatory effects on the host's immune system, the idea of combining angiogenic drugs with immunotherapy has emerged, and new clinical trials have been designed. In the last few years, several therapeutic options have been approved [immunotherapy and immunotherapy/tyrosine kinase inhibitors (TKI)] for the first-line treatment of mccRCC. Nivolumab/ipilimumab is approved for the treatment of patients with intermediate and poor prognoses. Several checkpoint inhibitors (pembrolizumab, nivolumab, avelumab) in combination with TKI (axitinib, lenvatinib, cabozantinib) are approved for the treatment of patients regardless of their International mRCC Database Consortium prognostic group and PD-L1 expression. There is no specific and ideal biomarker that could help in selecting the ideal patient for the appropriate first-line treatment.

Next-Generation Sequencing of Circulating Tumor DNA Can Optimize Second-Line Treatment in RAS Wild-Type Metastatic Colorectal Cancer after Progression on anti-EGFR Therapy: Time to Rethink Our Approach.

BACKGROUND: Management of Ras wild-type colorectal cancer (CRC) patients upon disease progression after the successful use of targeted treatment with anti-EGFR monoclonal antibodies and backbone chemotherapy remains a clinical challenge. SUMMARY: Development of treatment resistance with prevalence of preexisting RAS mutated clones, RAS mutation conversion, truncation of extracellular receptor domains as well as HER2 and MET amplification are molecular events that can be difficult to follow without the use of sophisticated laboratory techniques. The clinical hurdle of re-biopsy and tumor heterogeneity can be overcome by the implementation of next-generation sequencing (NGS) to analyze circulating tumor DNA (ctDNA) and identify druggable mutations or recovery of RAS-wildness. In this opinion paper, we summarize with critical thinking the clinical approach to be followed after the failure of first-line treatment in Ras wild-type CRC tumors with the use of NGS. Rechallenge with anti-EGFR inhibitors, in case of persistent or recovery of RAS-wildness, and targeted approach of specific mutations (BRAF inhibitors), amplifications (anti-Her2 treatment), or fusion proteins (NTRK inhibitors) can by guided by the use of NGS. The use of NGS platforms for serial analysis of ctDNA is an important step to better understand the molecular landscape of metastatic CRC and guide clinical decisions. KEY MESSAGES: NGS should be considered a mainstay in clinical practice for the management of CRC patients and health authorities should consider reimbursing its use in the appropriate clinical settings.

COVID-19 Vaccinations: Summary Guidance for Cancer Patients in 28 Languages: Breaking Barriers to Cancer Patient Information.

BACKGROUND: Covid-19 vaccination has started in the majority of the countries at the global level. Cancer patients are at high risk for infection, serious illness, and death from COVID-19 and need vaccination guidance and support. Guidance availability in the English language only is a major limit for recommendations' delivery and their application in the world's population and generates information inequalities across the different populations. METHODS: Most of the available COVID-19 vaccination guidance for cancer patients was screened and scrutinized by the European Cancer Patients Coalition (ECPC) and an international oncology panel of 52 physicians from 33 countries. RESULTS: A summary guidance was developed and provided in 28 languages in order to reach more than 70 percent of the global population. CONCLUSION: Language barrier and e-guidance availability in the native language are the most important barriers when communicating with patients. E-guidance availability in various native languages should be considered a major priority by international medical and health organizations that are communicating with patients at the global level.

Trilaciclib Prior to Chemotherapy in Patients with Metastatic Triple-Negative Breast Cancer: Final Efficacy and Subgroup Analysis from a Randomized Phase II Study.

PURPOSE: We report final antitumor efficacy results from a phase II study of trilaciclib, an intravenous cyclin-dependent kinase 4/6 (CDK4/6) inhibitor, administered prior to gemcitabine plus carboplatin (GCb) in patients with metastatic triple-negative breast cancer (NCT02978716). PATIENTS AND METHODS: Patients were randomized (1:1:1) to group 1 [GCb (days 1, 8); n = 34], group 2 [trilaciclib prior to GCb (days 1, 8); n = 33], or group 3 [trilaciclib (days 1, 8) and trilaciclib prior to GCb (days 2, 9); n = 35]. Subgroup analyses were performed according to CDK4/6 dependence, level of programmed death-ligand 1 (PD-L1) expression, and RNA-based immune signatures using proportional hazards regression. T-cell receptor (TCR) ß CDR3 regions were amplified and sequenced to identify, quantify, and compare the abundance of each unique TCRß CDR3 at baseline and on treatment. RESULTS: Median overall survival (OS) was 12.6 months in group 1, not reached in group 2 (HR = 0.31; P = 0.0016), 17.8 months in group 3 (HR = 0.40; P = 0.0004), and 19.8 months in groups 2 and 3 combined (HR = 0.37; P < 0.0001). Efficacy outcomes were comparable regardless of cancer CDK4/6 dependence status and immune signatures. Administering trilaciclib prior to GCb prolonged OS irrespective of PD-L1 status but had greater benefit in the PD-L1-positive population. T-cell activation was enhanced in patients receiving trilaciclib. CONCLUSIONS: Administering trilaciclib prior to GCb enhanced antitumor efficacy, with significant improvements in OS. Efficacy outcomes in immunologic subgroups and enhancements in T-cell activation suggest these improvements may be mediated via immunologic mechanisms.

Mutational profile of hereditary breast and ovarian cancer - Establishing genetic testing guidelines in a developing country.

PURPOSE: Because many countries lack the capacity to follow the international guidelines for genetic testing, we suggest the specific approach for establishing local genetic testing guidelines that could be applied in developing countries. We focus on hereditary breast (BC) and ovarian cancer (OC) in Serbia. METHODS: From the cohort of 550 persons who were referred for genetic counseling at the Institute for Oncology and Radiology of Serbia, 392 were selected. Personal and family histories were collected and germline DNA was sequenced with NGS in a panel of 20 genes. RESULTS: Pathogenic (PV) and likely-pathogenic variants (LPV) were detected in 8 genes with the frequency of 23.7%. The most frequent were in BRCA1(7.6%), BRCA2(4.8%), PALB2(4.1%) and CHEK2(3.8%). They were also detected in ATM(1.8%), NBN(0.8%), TP53(0.5%) and RAD51C(0.3%). Whereas high carrier probability (CP), bilateral BC, BC and OC in the same patient and family history (FH) of BC/OC, were the strongest predictors for BRCA1/2 PV/LPV, lower CP values and early age of BC onset without FH were associated with higher frequency of PALB2 and CHEK2 PV/LPV. CONCLUSIONS: Population specific studies to identify specific mutational patterns and predictors of PV/LPV should be conducted in order to make scientifically sound and cost-effective guidelines for genetic testing in developing countries.

COVID-19 vaccines and cancer patients: acceptance, attitudes and safety.

PURPOSE: Recommendations and guidelines consider cancer patients a high-priority population for COVID-19 immunization. Vaccination process in Serbia began in January 2021 with four available vaccines. We have conducted a cross-sectional study investigating cancer patients' acceptability of anti SARS-COV2 vaccines. METHODS: The study included 767 patients with solid and hematologic malignancies treated at the Oncology Institute of Vojvodina, Serbia. During July and August 2021 patients filled in an individual paper questionnaire on anti SARS-COV2 vaccination acceptance, preferences, side effects and information origin. Data on treatment phase, diagnosis and treatment was collected from electronic health records. RESULTS: During the first six months of vaccination campaign in Serbia 41% (320/767) of the investigated oncology patients received COVID-19 vaccines. The median age of vaccinated patients was 65 years (28-84). Most of them (75%) were in active treatment of cancer. Half of the unvaccinated patients (52%) wish to get vaccinated after the end of their cancer treatment. Around 10% of the patients definitely refused vaccination. The majority of information on COVID-19 vaccines cancer patients got from their oncologist, television and newspapers. Side effects were reported by 10.93% of the patients after the first dose and 13,31% after the second dose. No serious side effects were reported. CONCLUSION: We have confirmed that patients are reluctant of receiving vaccine due to fear of side effects, especially during the active cancer treatment. However, real-world evidence and clinical trials data have gathered enough evidence to reassure any doubts of the patients and their oncologists on safety and efficacy of anti SARS-COV2 vaccines.

Immunotherapy in the treatment of lymphoma.

Relapsed or refractory non-Hodgkin's lymphomas, especially diffuse large B-cell lymphoma as well as relapsed or refractory Hodgkin lymphomas are hard-to-treat diseases. Patients who do not respond to initial therapy or experience relapse are treated with salvage regimens, and if eligible for aggressive therapy, treatment is continued with high-dose chemotherapy and autologous stem cell transplantation. Current therapy options can cure substantial numbers of patients, however for some it is still an uncurable disease. Numerous new drugs and cell therapies are being investigated for the treatment of relapsed or refractory lymphomas. Different types of immunotherapy options have shown promising results, and some have already become the standard of care. Here, we review immunotherapy options for the treatment of lymphoma and discuss the results, positions, practical aspects, and future directions of different drugs and cellular therapies for the treatment of this disease.

A phase I, open-label study evaluating the safety and pharmacokinetics of trifluridine/tipiracil in patients with advanced solid tumors and varying degrees of renal impairment.

PURPOSE: Trifluridine/tipiracil (FTD/TPI) is approved for advanced colorectal and gastric/gastroesophageal cancer; however, data in patients with renal impairment (RI) are limited. This phase I study evaluated FTD/TPI in patients with advanced solid tumors and varying degrees of RI to develop dosing guidance. METHODS: Patients were enrolled into normal renal function (CrCl ≥ 90 mL/min), mild RI (CrCl 60-89 mL/min), or moderate RI (CrCl 30-59 mL/min) cohorts and administered the recommended FTD/TPI dose (35 mg/m2 twice daily, days 1-5 and 8-12; 28-day cycle). Based on interim pharmacokinetics/safety data, patients with severe RI (CrCl 15-29 mL/min) were enrolled and received FTD/TPI 20 mg/m2 twice daily. RESULTS: Forty-three patients (normal renal function [n = 12]; mild RI [n = 12]; moderate RI [n = 11]; severe RI [n = 8]) were enrolled and treated. At steady state, compared to values in patients with normal renal function, FTD area under the curve (AUC) was not significantly different in patients with RI, but TPI AUC was significantly higher and increased with RI severity. FTD/TPI safety profile was consistent with prior experience, but grade ≥ 3 adverse events (AEs) were more frequent in the RI cohorts (83.3% [mild], 90.9% [moderate], 75.0% [severe], and normal [50.0%]). Hematologic AEs (anemia and neutropenia) were more frequent with RI. Overall, seven patients discontinued because of unrelated, nonhematologic AEs. CONCLUSION: FTD/TPI is safe and tolerable at the recommended 35 mg/m2 dose in patients with mild/moderate RI and at the reduced 20 mg/m2 dose in patients with severe RI. TRIAL REGISTRATION: NCT02301117, registration date: November 21, 2014.

Synthesis of Recommendations From 25 Countries and 31 Oncology Societies: How to Navigate Through Covid-19 Labyrinth.

INTRODUCTION: Pandemic COVID-19 is an unexpected challenge for the oncological community, indicating potential detrimental effects on cancer patients. Our aim was to summarize the converging key points providing a general guidance in order to support decision making, pertaining to the oncologic care in the middle of a global outbreak. METHODS: We did an international online search in twenty five countries that have managed a surge in cancer patient numbers. We collected the recommendations from thirty one medical oncology societies. RESULTS: By synthesizing guidelines for a) oncology service delivery adjustments, b) general and specific treatment adaptations, and c) discrepancies from guidelines comparison, we present a clinical synopsis with the forty more crucial statements. A Covid-19 risk stratification base was also created in order to obtain a quick, objective patient assessment and a risk-benefit evaluation on a case-by-case basis. CONCLUSIONS: In an attempt to face these complex needs and due to limited understanding of COVID-19, a variability of recommendations based on general epidemiological and infectious disease principles rather than definite cancer-related evidence has evolved. Additionally, the absence of an effective treatment or vaccine requires the development of cancer management guidance, capitalizing on comprehensive COVID-19 oncology experience globally.

A review of the international early recommendations for departments organization and cancer management priorities during the global COVID-19 pandemic: applicability in low- and middle-income countries.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a new virus that has never been identified in humans before. COVID-19 caused at the time of writing of this article, 2.5 million cases of infections in 193 countries with 165,000 deaths, including two-third in Europe. In this context, Oncology Departments of the affected countries had to adapt quickly their health system care and establish new organizations and priorities. Thus, numerous recommendations and therapeutic options have been reported to optimize therapy delivery to patients with chronic disease and cancer. Obviously, while these cancer care recommendations are immediately applicable in Europe, they may not be applicable in certain emerging and low- and middle-income countries (LMICs). In this review, we aimed to summarize these international guidelines in accordance with cancer types, making a synthesis for daily practice to protect patients, staff and tailor anti-cancer therapy delivery taking into account patients/tumour criteria and tools availability. Thus, we will discuss their applicability in the LMICs with different organizations, limited means and different constraints.
