Survey of the impact of COVID-19 on oncologists’ decision making in cancer
PURPOSE
To understand readiness measures taken by oncologists to protect patients and health care workers from the novel coronavirus (COVID-19) and how their clinical decision making was influenced by the pandemic.
METHODS
An online survey was conducted between March 24 and April 29, 2020.
RESULTS
A total of 343 oncologists from 28 countries participated. The median age was 43 years (range, 29-68 years), and the majority were male (62%). At the time of the survey, nearly all participants self-reported an outbreak in their country (99.7%). Personal protective equipment was available to all participants, of which surgical mask was the most common (n = 308; 90%). Telemedicine, in the form of phone or video encounters, was common and implemented by 80% (n = 273). Testing patients with cancer for COVID-19 via reverse transcriptase polymerase chain reaction before systemic treatment was not routinely implemented: 58% reported no routine testing, 39% performed testing in selected patients, and 3% performed systematic testing in all patients. The most significant factors influencing an oncologist’s decision making regarding choice of systemic therapy included patient age and comorbidities (81% and 92%, respectively). Although hormonal treatments and tyrosine kinase inhibitors were considered to be relatively safe, cytotoxic chemotherapy and immune therapies were perceived as being less safe or unsafe by participants. The vast majority of participants stated that during the pandemic they would use less chemotherapy, immune checkpoint inhibitors, and steroids. Although treatment in neoadjuvant, adjuvant, and first-line metastatic disease was less affected, most of the participants stated that they would be more hesitant to recommend second- or third-line therapies in metastatic disease.
CONCLUSION
Decision making by oncologists has been significantly influenced by the ongoing COVID-19 pandemic
Sekonder Önlem Hastalarında Kardiyovasküler Riski Azaltmada PCSK9 İnhibitör Gereksinimine Özel Vurgu ile Lipit Modifikasyonu: Delphi Panel Yaklaşımına Dayalı Bir Analiz
Objective: The aim of this study is to analyze the low-density lipoprotein cholesterol-lowering therapies in secondary prevention patients by analyzing their plasma low-density lipoprotein cholesterol levels, current treatment, considering their inadequate response to medications (as defined in current guidelines), and the requirement for a protein convertase subtilisin/kexin type 9 inhibitor. Methods: Delphi panel is used to seek expert consensus of experienced 12 cardiologists. A questionnaire consisting of 6 main questions is used to reflect the opinion of the expert panelists on the practices of low-density lipoprotein cholesterol-lowering therapies of patients with high and very high cardiovascular risk. Patients with atherosclerotic cardiovascular disease are covered in this present analysis. Results: According to expert opinion data, 18.6% of the patient population with atherosclerotic cardiovascular disease is estimated to have experienced recurrent vascular events. The current treatment of the patient population is 39.7% on high dose, 36.9% on low/moderate dose of statin, 13.1% on maximum tolerated dose statin + ezetimibe, and 1.2% on maximum tolerated dose statin + ezetimibe + protein convertase subtilisin/kexin type 9 inhibitor. The percentage of atherosclerotic cardiovascular disease patients with inadequate treatment response is estimated to be 20.2% in those using “maximum tolerated dose statin + ezetimibe.” The proportion of patients who will need to be treated with a protein convertase subtilisin/kexin type 9 inhibitor increases as their low-density lipoprotein cholesterol levels rises from 9.1% in 70-99 mg/dL to 50.8% in ?160 mg/dL for these patients. Conclusion: According to expert opinion, although a substantial proportion of patients with secondary prevention have not achieved low-density lipoprotein cholesterol goals, the use of protein convertase subtilisin/kexin type 9 inhibitors is very low. Since the questionnaire subject to panel discussion did not include any question elaborating the issue, the discrepancy between the recommendation of the related guidelines and Turkish practice needs further studies for the explanation. © 2022 Turkish Society of Cardiology.

Atezolizumab in Patients with Metastatic Urothelial Carcinoma Who Have Progressed After First-line Chemotherapy: Results of Real-life Experiences
Background: Atezolizumab (ATZ) has demonstrated antitumor activity and manageable safety in previous studies in patients with locally advanced or metastatic platinum-resistant urothelial carcinoma. Objective: To compare the real-life experience and data of clinical trials on ATZ treatment in metastatic urothelial carcinoma. Design, setting, and participants: Patients with urothelial cancer treated with ATZ after progression on first-line chemotherapy from an expanded access program were retrospectively studied. Data of patients were obtained from their files and hospital records. Safety was evaluated for patients treated with at least one cycle of ATZ. Outcome measurements and statistical analysis: The primary endpoint was objective response rate (ORR). The secondary endpoints are overall survival (OS), progression-free survival (PFS), duration of response, and safety profile of patients. Kaplan-Meier methods were used to calculate median follow-up and estimate PFS and OS. Results and limitations: Data of 115 enrolled patients were analyzed. Most of the patients (92.3%, n = 106) had received chemotherapy regimen only once prior to ATZ. The median follow-up duration was 23.5 mo. The complete response rate, partial response rate, and ORR were 8.7% (n = 10), 20.0% (n = 23), and 28.7% (n = 33), respectively. The median duration of response was 20.4 mo (95% confidence interval [CI], 6.47–28.8). Of the 33 patients who responded to treatment, 60% (n = 20) had an ongoing response at the time of the analysis. PFS and OS with ATZ were 3.8 mo (95% CI, 2.25–5.49) and 9.8 mo (95% CI, 6.7–12.9), respectively. All-cause and any-grade adverse events were observed in 113 (98%) patients. Of the patients, 64% experienced a treatment-related adverse event of any grade and 24 (21.2%) had a grade 3–4 treatment-related adverse event. Limitations of the study included its retrospective design, and determination of treatment response based on clinical notes and local radiographic studies. Conclusions: In these real-life data, ATZ was effective and well tolerated in patients with metastatic urothelial carcinoma who have progressed with platinum-based first-line chemotherapy. ATZ is an effective and tolerable treatment for patients with locally advanced or metastatic platinum-resistant urothelial carcinoma in our study, similar to previously reported trials. Patient summary: Atezolizumab is effective and well-tolerated in patients with metastatic urothelial cancer who progressed with first-line chemotherapy, consistent with the outcomes of the previous clinical trials in this setting. Atezolizumab is an effective and tolerable treatment option for patients with urothelial cancer after progression by the chemotherapy. Clinical activity and safety of atezolizumab treatment in real-life patients were consistent with the outcomes of the previous clinical trials in this setting © 202
Established and new treatment roadmaps for pleural mesothelioma: opinions of the Turkish Collaborative Group
Pleural mesothelioma (PM) is a cancer of the pleural surface, which is aggressive and may be rapidly fatal. PM is a rare cancer worldwide, but is a relatively common disease in Turkey. Asbestos exposure is the main risk factor and the most common underlying cause of the disease. There have been significant improvements in diagnoses and treatments of many malignancies; however, there are still therapeutic challenges in PM. In this review, we aimed to increase the awareness of health care professionals, oncologists, and pulmonologists by underlining the unmet needs of patients with PM and by emphasizing the need for a multidisciplinary treatment and management of PM. After reviewing the general information about PM, we further discuss the treatment options for patients with PM using immunotherapy and offer evidence for improvements in the clinical outcomes of these patients because of these newer treatment modalities. © 2023 The Author(s)This work was supported by Bristol Myers Squibb, Istanbul, Turkey .Bristol-Myers Squibb, BM
Combination of trastuzumab and taxane-containing intensified chemotherapy in first-line treatment of HER2-positive advanced gastric cancer
Purpose: Taxane-containing combinations are recommended for the first-line therapy of advanced gastric cancer. It is not known which chemotherapy regimen is the best with trastuzumab for HER2-positive patients. The aim of this study was to compare taxane-containing intensified chemotherapy versus standard chemotherapy in combination with trastuzumab in the first-line treatment of HER2-positive advanced gastric adenocarcinoma. Methods: This study is a retrospective multicenter study of the Turkish Oncology Group. A total of 130 HER2-positive patients with inoperable locally advanced, recurrent, or metastatic gastric adenocarcinoma being given chemotherapy plus trastuzumab as the first-line treatment were included from 16 different oncology centers. Trastuzumab combination with intensified chemotherapy including taxane or standard chemotherapy was compared in terms of progression-free survival (PFS), overall survival (OS), and toxicity. Results: There were 108 patients in the standard and 22 patients in the intensified chemotherapy group. PFS of the standard and intensified group were 5.6 months (95% confidence interval [CI] 4.8–6.4) and 5.3 months (95% CI 2.6–8), respectively (p = 0.70). OS of the standard and intensified group were 11.1 months (95% CI 8.3–13.9) and 15.2 months (95% CI 12.7–17.7), respectively (p = 0.03). Repeated analysis excluding patients given any previous therapy revealed similar results. The intensified group had more fever and febrile neutropenia. Conclusion: Trastuzumab combination with intensified chemotherapy provides better OS in first-line treatment of HER2-positive advanced gastric cancer. Further large-scale studies should be performed in HER2-positive patients. © Fondazione IRCCS Istituto Nazionale dei Tumori 2020
Clinical features and outcomes of COVID-19 in patients with solid tumors: Turkish National Registry Data
We present demographic, clinical, laboratory characteristics and
outcomes of the patients with solid malignancies and novel coronavirus
disease (COVID-19) collected from the National COVID-19 Registry of
Turkey. A total of 1523 patients with a current or past diagnosis of
solid tumors and diagnosed with COVID-19 (confirmed with PCR) between 11
March and 20 May 2020 were included. The primary outcome was 30-day
mortality. Median age was 61 (range: 18-94), and 752 (49\%) were male.
The most common types of cancers were breast (19.8\%), prostate (10.9\%)
and colorectal cancer (10.8\%). 65\% of the patients had at least one
comorbidity. At least one COVID-19-directed therapy was given in 73\% of
the patients.. Hospitalization rate of the patients was 56.6\% and
intensive care unit admission rate was 11.4\%. Seventy-seven (5.1\%)
patients died within 30 days of diagnosis. The first multivariate model
which included only the demographic and clinical characteristics showed
older age, male gender and presence of diabetes and receipt of cytotoxic
therapy to be associated with increased 30-day mortality, while breast
and prostate cancer diagnoses were associated with lower 30-day
mortality. In the second set, we further included laboratory parameters.
The presence of leukocytosis (OR 6.7, 95\% CI 3.3-13.7, P < .001),
lymphocytopenia (OR 3,1, 95\% CI 1,6-6,1, P = .001) and thrombocytopenia
(OR 3,4 95\% CI 1,5-8,1, P = .005) were found to be associated with
increased 30-day mortality. Relatively lower mortality compared to
Western countries and China mainly results from differences in baseline
risk factors but may also implicate the importance of intensive
supportive care
