Metastatic ovarian cancer to the breast is a rare presentation, with limited cases reported worldwide. Common sites for distant metastasis in ovarian cancer are to the liver, lung, and pleura [Dauplat et al. Cancer. 1987 Oct 1;60(7):1561-6]. Usually, such cases predict poor prognosis with troublesome management. We present one challenging case of a 54-year-old female patient with recurrent clear cell ovarian cancer, presenting with right breast mass of primary versus secondary origin, progressing into inflammatory breast cancer picture. Our report aims to shed light on the value of early suspicion and low threshold of detecting secondary breast masses of ovarian cancer origin.
Background The economic benefit of the clinical pharmacist's role in ensuring the optimum use of medicines is potentially considerable, particularly when it comes to cancer management. We sought to evaluate the overall economic impact of clinical pharmacist interventions in the main cancer setting in Qatar. Methods The total economic benefit of the clinical pharmacy interventions were analyzed from the public hospital perspective. Patient records in March 2018, July/August 2018, and January 2019 were retrospectively reviewed at the National Center for Cancer Care and Research, Qatar. The total benefit from interventions was the total cost avoidance due to preventable adverse drug events plus any cost savings associated with therapeutic-based resource use. Sensitivity analyses confirmed the results’ robustness and increased generalizability. Results A total of 1352 interventions based on 281 patients were analyzed. The majority of the drug-related problems were related to the appropriateness of therapy, followed by dosing and administration. The total population benefit over the 3-months study period was QAR 4,879,185 (USD 1,336,763), constituting cost avoidance of QAR 4,234,012 (USD 1,160,003) and negative resource-use cost savings of −QAR 645,174 (−USD 176,760). Projected annual overall benefit was QAR 14,355,354 (USD 3,932,974). The increase in resource use with therapies was mostly because of the addition of other medications. Cost avoidance was mostly driven by recommending additional medications and discontinuation of medications. The uncertainty analysis demonstrated the robustness of outcomes. Conclusions The clinical pharmacist intervention increased resource use and its cost. In overall, however, taking avoided cost of adverse drug events in consideration, it is an economically beneficial practice in the National Center for Cancer Care and Research setting, associated with adverse drug events prevention and substantial economic benefits.
<b><i>Introduction:</i></b> Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the viral agent responsible for the coronavirus disease of 2019. The disease is primarily a respiratory illness; however, multisystem involvement is not uncommon. The infection is reported to be more severe in patients with multiple comorbidities and immunocompromised patients. Patients with hematological malignancies are immunocompromised and prone to develop severe SARS-CoV-2 infection. The SARS-CoV-2 had developed several mutations that resulted in different strains with different virulence and different degree of protection by vaccination or prior infection. The Omicron variant is reported to cause mild illness; however, the effect on patients with hematological malignancies like myeloproliferative neoplasms (MPNs) is not clear. We present patients with MPNs who had infection with the Omicron variant of the SARS-CoV-2 and their outcomes. <b><i>Methods:</i></b> Retrospective data from the National Center for Cancer Care and Research records from December 20, 2021, to January 30, 2022. Participants were adults over the age of 18 years with Omicron infection who had been diagnosed with Philadelphia-negative MPNs, essential thrombocythemia, polycythemia vera (PV), and primary myelofibrosis according to the 2008/2016 WHO classification for MPN. <b><i>Results:</i></b> Twenty-two patients with Philadelphia-negative MPN had Omicron infection. All patients had a mild disease according to the WHO classification of COVID-19 severity. Most of the patients had medical comorbidities, with hypertension being the most common comorbidity. However, only one patient with PV required hospitalization. <b><i>Discussion/Conclusions:</i></b> In patients with Philadelphia-negative MPN, the Omicron variant of SARS-CoV-2 usually results in mild infection.
Background and aims Coronavirus disease 2019 (COVID-19) is caused by a virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since the first pandemic wave, SARS-CoV-2 had developed significant changes and mutations that resulted in the emergence of different strains. Each strain varies in its virulence and disease severity. Most reports have shown that the Omicron variant causes mild illness. Little is known about the impact of Omicron in patients with chronic myeloid leukemia. We present patients with chronic myeloid leukemia who had infection with the Omicron variant of the SARS-CoV-2 and their outcomes. Materials and methods Retrospective data from the records of the National Center for Cancer Care and Research from December 20, 2021, to January 30, 2022. Participants were adults over the age of 18 years with Omicron infection who had been diagnosed with chronic myeloid leukemia according to World Health Organization classifications from 2008 and 2016. Results Eleven patients with chronic myeloid leukemia had Omicron infection. All patients had a mild disease according to the World Health Organization classification of COVID-19 severity. The majority of patients were young males. Conclusions In patients with chronic myeloid leukemia, infection with the Omicron variant of the SARS-CoV-2 usually results in mild disease not requiring hospitalization.
Myeloproliferative neoplasms are a diversified group of diseases of the hematopoietic stem cell, such as essential thrombocythemia (ET) and polycythemia vera. They are mainly caused by mutations in the following genes: JAK2, CALR, and MPL. All carry an increased risk to transform into acute leukemia or chronic myelogenous leukemia along with thrombosis and hemorrhagic complications. Treatment of such disorders during pregnancy is a challenging footstep, given the high risk of complications for both the mother and the fetus. Here, we report about two pregnant females with ET that has been treated with pegylated interferon alpha with safe and effective outcome.
Chronic myelogenous leukemia (CML), also known as chronic myeloid leukemia, is a myeloproliferative neoplasm characterized by increased proliferation of the granulocytic cell line without loss of its capacity to differentiate. It accounts for 20% of all adults affected by leukemia. Tyrosine kinase inhibitors revolutionized the treatment for CML and improved quality of life. Fertility is an important issue for both males and females. Here, we report our experience with a pregnant female with CML, and shed light on safety and efficacy of PEGylated interferon-αa in pregnant women with CML and its outcome.
Background Immune thrombocytopenia (ITP) is a blood disorder in which antibodies coating platelets cause platelet destruction in the spleen with a resultant low platelet count and an increased tendency for bleeding. Coronavirus disease 2019 (COVID-19) is an illness caused by SARS-CoV-2. Though pneumonia and respiratory failure are major causes of morbidity and mortality, multisystemic complications were identified, including hematological ones. Several ITP relapse cases post-mRNA SARS-CoV-2 vaccines have been reported, and different pathophysiological theories have been proposed. Purpose The objective of this study is to identify the causal relationship between mRNA COVID-19 vaccines and ITP relapse, to highlight the longer-term effect of these vaccines on the platelet count more than 6 months after receiving the vaccine, and to identify if there is a statistical difference between Comirnaty and Spikevax vaccines on ITP relapse rate. Patients and Methods In this retrospective study, 67 patients with known ITP were followed before and after receiving the mRNA COVID-19 vaccine. The follow-up parameters included platelet counts when available and bleeding symptoms. All patients were adults over 18 years old, with no other identified causes of thrombocytopenia. Forty-seven patients received the Comirnaty vaccine, and 20 patients received the Spikevax vaccine. Results Data analysis showed 6% ITP relapse in the first 3 months, and a 10% relapse rate 3–6 months after receiving one of the mRNA COVID-19 vaccines, with no statically significant difference between the two vaccines. Conclusion mRNA COVID-19 vaccines increase the risk of ITP relapse and can lead to a prolonged reduction in platelet count in a proportion of ITP patients, with no statistically significant difference between Comirnaty and Spikevax vaccines.
The coexistence of dual hematological neoplasms is an unusual and challenging presentation due to the different combination of etiopathology. The presentation of synchronous dual hematological malignancies can be one of the 3 types: myeloid + lymphoid or dual lymphoid or dual myeloid. Here, we are reporting a case of a 53-year-old male with simultaneous presence of JAK<i>2 V617F</i>-positive myeloproliferative neoplasm with features favoring prefibrotic phase of primary myelofibrosis (pre-PMF) in combination with monoclonal gammopathy of undetermined significance (MGUS). In such cases of simultaneous existence of dual hematological neoplasm management, it is recommended to treat the more aggressive one. Currently, our management plan is focusing on treating the pre-PMF and observation of MGUS with regular monitoring for transformation to MM.
