BackgroundThe risk of thromboembolic events is higher among cancer patients, especially in patients undergoing chemotherapy. Cisplatin-based regimens claim to be associated with a very high thromboembolic rate. In this study, we report on our own experience with thrombosis among patients on active cisplatin-based chemotherapy.MethodsMedical records and hospital databases were searched for all the patients treated with any cisplatin-based regimen for any kind of cancer. Thrombosis was considered cisplatin-related if diagnosed any time after the first dose and up to 4 weeks after the last. The Khorana risk assessment model was performed in all cases.ResultsA total of 1677 patients (65.5% males, median age: 50 years) treated with cisplatin-based regimens were identified. Head and neck (22.9%), lung (22.2%), lymphoma and gastric (11.4% each) were the most common primary tumors. Thromboembolic events were reported in 110 (6.6%); the highest was in patients with gastric cancer (20.9%) and the lowest in patients with head and neck cancers (2.3%) and lymphoma (1.6%). Thrombosis included deep vein thrombosis (DVT) in 69 (62.7%), pulmonary embolism (PE) in 18 (16.9%) and arterial thrombosis in 17 (15.6%). A majority (51.1%) of the patients had stage IV disease and only 16% had stage I or II.In a multivariate analysis, significantly higher rates of thrombosis were associated with gastric as the primary tumor, advanced-stage disease, female sex but not age, and the Khorana risk score or type of cisplatin regimen. While the presence of CVC was significantly associated with the risk of thrombosis (p < 0.0001) in the univariate analysis, and such significance was lost in the multivariate analysis (odds ratio, 1.098; 95%CI, 0.603–1.999, p = 0.7599).ConclusionsThromboembolic events in cancer patients on active cisplatin-based chemotherapy were commonly encountered. Gastric cancer, regardless of other clinical variables, was associated with the highest risk.
PurposeCompared to Western societies, breast cancer diagnosis in our region is usually made at a younger age and at a more advanced stage. Breast cancer in younger patients tends to be more aggressive, and may result in a higher likelihood of long-term treatment-related toxicity and unique psychosocial problems. This study highlights the clinicopathological features and treatment outcomes in this age-group in a developing country like ours.MethodsConsecutive patients aged 40 years or younger with a pathologically confirmed diagnosis of breast cancer treated and followed up at our institution were included. Medical records and hospital databases were searched for patients’ characteristics and treatment outcomes.ResultsA total of 417 patients were enrolled. Median age at diagnosis was 35 (21–40) years. On presentation, 63 (15.1%) patients had metastatic disease, 50 (79.4%) with visceral metastasis. Patients with nonmetastatic disease had poor pathological features, including node-positivity (66.9%), grade III (51.4%), lymphovascular invasion (48.6%) and positive HER2 (31.5%). Breast-conserving surgery was performed on 32.9%, and only 36.5% of women had breast-reconstruction surgery. At a median follow-up of 59 months, 5-year overall survival for the whole group was 72%: 84% for nonmetastatic and 13% for those with metastatic disease. On Cox regression, nodal metastasis (adjusted HR 3.46, 95% CI 1.48–8.10; p=0.004) and grade III disease (HR 1.97, 95% CI 1.14–3.39; p=0.015) were associated with poor outcome.ConclusionAdolescents and young Jordanian adults with breast cancer present with more advanced–stage disease and more aggressive pathological features that reflect poorly on treatment outcomes.
Purpose Cyclin dependent kinase (CDK) 4/6 inhibitors (palbociclib, ribociclib and abemaciclib) modulate endocrine resistance and are integral treatment for patients with advanced hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Since their approval, CDK4/6 inhibitors are widely used in clinical practice. Thromboembolic events (TEE) were not a major issue in patients treated on clinical trials utilizing these agents. However, conflicting data started to emerge describing higher than expected rates of both arterial and venous thrombosis in patients treated with CDK4/6 inhibitors. In this study, we report our experience on TEE in patients treated with one of these agents (ribociclib) in real-world settings. Patients and Methods All consecutive patients with metastatic breast cancer (mBC) treated with ribociclib combined with letrozole or fulvestrant were retrospectively reviewed. All episodes of radiologically confirmed arterial or venous thrombosis were recorded. TEE was considered ribociclib-related if diagnosed while patients are on the drug, or within 4 weeks after the last dose. Results A total of 305 patients, median age (range), 49 (22–87) years were enrolled. All patients had metastatic disease, and most (n=241, 79.0%) were with visceral metastasis. Ribociclib was used for a median duration of 7 months (range: 1–45) and was used beyond the first-line setting in 110 (35.9%) patients. TEE were confirmed on 6 (1.97%) patients; 3 were pulmonary embolism, 2 cerebral venous sinus thrombosis (CVST), and one case of limb ischemia and all were symptomatic. Similar rates of TEE were noted prior to initiation, and after stopping ribociclib. Conclusion In real-world settings, breast cancer patients treated with ribociclib, combined with aromatase inhibitors or fulvestrant, may not be at higher risk for thromboembolic events. However, unusual sites of thrombosis, like CVST, may raise some concerns.
In Jordan, an Arabic Islamic country, decisions around withholding and/or withdrawing life support measures still present both moral and professional dilemmas. The purpose of this study was to explore the use of such measures among patients with cancer in Jordan. The medical records of 436 patients with cancer who were at least 18 years old and who died at a specialized cancer centre in Jordan in 2008 were reviewed retrospectively. Of those, 212 (48.6%) had a written decision to withhold or withdraw life support measures. Among the 436 charts reviewed, only 7 patients (1.6%) had treatment withdrawn, while 212 (48.6%) had treatment withheld. Resuscitation was the most common treatment withheld, followed by medication, and poor prognosis was the most common reason for the decision. The time period between a decision being made and the death of the patient was short, indicating that treatment plans are not being made well in advance. A cultural and religious consensus regarding such decisions is needed to help ensure that a greater proportion of terminally ill people plan their care in advance, and to aid health-care providers in advising their patients and acting in the patients' best interests.
Purpose:Cancer and its treatment are recognized risk factors for venous thromboembolism (VTE); active cancer accounts for almost 20% of all newly diagnosed VTE. Inferior vena cava (IVC) filters are utilized to provide mechanical thromboprophylaxis to prevent pulmonary embolism (PE) or to avoid bleeding from systemic anticoagulation in high-risk situations. In this report, and utilizing a case study, we will address the appropriate utilization of such filters in cancer patients.Methods:The case of a 43-year-old female patient with rectal cancer, who developed deep vein thrombosis following a complicated medical course, will be presented. The patient was anticoagulated with a low molecular weight heparin, but a few months later and following an episode of bleeding, an IVC filter was planned. Using the PubMed database, articles published in English language addressing issues related to IVC filters in cancer patients were accessed and will be presented.Results:Many recent studies questioned the need to insert IVC filters in advanced-stage cancer patients, particularly those whose anticipated survival is short and prevention of PE may be of little clinical benefit and could be a poor utilization of resources.Conclusion:Systemic anticoagulation can be safely offered for the majority of cancer patients. When the risk of bleeding or pulmonary embolism is high, IVC filters can be utilized. However, placement of such filters should take into consideration the stage of disease and life expectancy of such patients.
