Naples prognostic score may predict overall survival in metastatic pancreatic cancer.

INTRODUCTION: Naples prognostic score (NPS) based on nutritional and inflammatory parameters can predict response to chemotherapy and overall survival (OS) in many cancer types. However, its significance in metastatic pancreatic cancer (PC) remains unclear. We evaluated the prognostic significance of the NPS in patients with metastatic PC receiving first line chemotherapy. METHODS: We retrospectively analyzed 215 patients with metastatic PC receiving first line FOLFIRINOX chemotherapy. NPS's were calculated using pre-chemotherapy laboratory data. Patients were divided into three groups according to their scores (NPS: 0; 1 & 2; 3 & 4 were grouped as 1, 2 and 3, respectively). The association of NPS with clinicopathological features and OS were evaluated. RESULTS: Median age was 64 years, and median OS was 10.5 months. Hemoglobin levels were lower and Ca-19-9 values were higher with increasing NPS. Frequency of patients with bone and/or liver metastases, and with greater than 5 metastatic focus were higher in group 3. A lower NPS was associated with longer OS. The median OS in groups 1, 2, and 3 were 19.5, 12, and 8 months, respectively, and differed significantly. Univariate analysis revealed effect of NPS (3-4) on OS (HR: 2.38, 1.77-3.19). Other prognostic factors affecting OS were age, ECOG, liver, bone or lymph node metastases, number of metastatic foci (<5 vs >5), de-novo metastatic disease, and serum Ca-19-9 levels. NPS (3-4) was identified as an independent prognostic factor negatively affecting OS (HR: 1.89, 1.34-2.65) in multivariate analysis. CONCLUSION: NPS may be a useful prognostic marker for the prediction of OS in metastatic PC patients receiving systemic chemotherapy.

Pralatrexate for Peripheral T-Cell Lymphoma (PTCL): Chance Only Supports The Prepared Mind.

BACKGROUND: Due to their primary effects on DNA synthesis, antimetabolites are most effective against actively dividing cells and are significantly specific to the cell cycle phase. Pralatrexate (PDX), an antifolate metabolite designed to accumulate in cancer cells, was the first new agent approved by the US Food and Drug Administration for the treatment of resistant/recurrent peripheral T-cell lymphomas. PDX was a drug that is frequently used not only for PTCL, but also for cutaneous T-cell lymphoma (CTCL), extranodal natural killer (NK) / T-cell lymphoma. OBJECTIVE: This article reviews Pralatrexate's history, pharmacokinetics, clinical phase studies including phases I, II and III, types of cancers it is effective on, drug side effects, inhibition mechanism and even its use in the treatment of other cancers with innovative methods, including its antiviral effect against SARS-CoV-2 infection. METHODS: A comprehensive internet-based research was planned, covering all published and unpublished studies on the subject. We conducted this review in accordance with Preferred Reporting Items for systematic reviews and metaanalysis (PRISMA-P), and Cochrane Collaboration reporting items for systematic reviews and meta-analysis. The results of the studies in the articles were recorded to include all phase studies. RESULTS: Pralatrexate was structurally designed to have enhanced cellular transport via RFC (reduced folate carrier type) and be subject to more polyglutamation compared to methotrexate. The enhanced polyglutamylation ability of pralatrexate is associated with increased tumor cell death and ultimately improved anticancer activity. Pralatrexate is considered a promising drug for patients with recurrent and treatment-resistant PTCL with a good survival advantage. At the same time, it is an antifolate agent with a significant advantage over methotrexate as it does not cause myelosuppression. CONCLUSION: While there are manageable side effects such as thrombocytopenia, neutropenia, and mucositis, it is critical to explore new approaches, targeted agents, novel cellular therapies, and immunotherapies to determine optimal pretreatment in the rare but heterogeneous disease PTCL, and future studies and experienced haematologists are needed.

Salvage Intrapartum Splenectomy for the Treatment of Transfusion-refractory Anaemia in a ß-thalassemia Intermedia Patient.

Thalassemia intermedia (TI) patients may need a transfusion during physiological stress conditions, such as pregnancy. We present a case of a female TI patient with emerging transfusion-refractory anaemia during pregnancy, which resolved after splenectomy performed simultaneously with cesarean delivery. A 26-year pregnant woman at 29th gestational weeks was referred with a diagnosis of TI due to emerging anaemia which was refractory to transfusion. Splenectomy at term was decided to improve anaemia, and transfusion response. A preterm infant was delivered by cesarean section due to threatened preterm labour. Once the uterine incision was closed, an open splenectomy was performed. Postoperative follow-up was uneventful. To the best of our knowledge, the present case is the first open splenectomy performed during cesarean delivery as a salvage option for the management of transfusion-refractory anaemia. Key Words: Thalassemia intermedia, Splenectomy, Pregnancy, Hemolytic anaemia.

Ribociclib induced acute kidney injury: A case report.

INTRODUCTION: Among females, breast cancer is the most common type of cancer. Hormon receptor positive (HR+) subtype constitutes 75% of the diagnosed breast cancers. Combination of the cyclin D-cyclin-dependent kinase 4/6 (CDK4/6) inhibitor and endocrine therapy significantly improves overall survival and progression-free survival. Ribociclib is an oral CDK 4/6 inhibitor and some adverse effects are identified. According to MONALEESA 2-3-7 studies, no adverse effect (AE) were reported due to grade 3 or 4 acute kidney injury (AKI) that caused treatment discontinuation. CASE REPORT: We report a ribociclib-induced grade 3 AKI in an elderly woman who was treated for metastatic breast cancer. During first cycle of therapy, she was admitted to the oncology clinic with diagnosis of AKI.Management and outcome: Ribociclib treatment was discontinued and secondary causes of AKI were excluded. During the follow-up, kidney function values returned to the normal range spontaneously. Ribociclib treatment was re-initiated by reducing the dose (400 mg daily). Despite dose reduction; grade 3 AKI recurred when ribociclib was re-initiated and the drug was permanently discontinued. DISCUSSION: According to MONALEESA 2-3-7 studies; no AE were reported due to grade 3 or 4 AKI. Despite these studies, the FDA reported that 20% of patients with ribociclib + letrozole combination therapy may have any stage elevation of creatinine. Ribociclib induced creatinine elevations are generally mild (grade 1-2) and can be managed by dose reduction or close monitoring of creatinine levels. We report the first case of grade 3 AKI that caused treatment discontinuation following administration of ribociclib.
