Filter by:Medullary thyroid carcinoma (MTC) is a tumor originating from parafollicular C cells of the thyroid. (1) Representing 1 to 7% of all thyroid carcinoma cases (2, 3, 4). It can occur in two clinical forms, the sporadic or non-hereditary, in 75-80% of patients, and the hereditary form in the remaining 20-25%. It can be part of different clinical syndromes depending on the organs involved: Multiple Endocrine Neoplasia type 2A (MEN2A), Multiple Endocrine Neoplasia type 2B (MEN2B) and Familial Medullary Thyroid Carcinoma (FCM) whose clinical expression is only CMT. A distinctive characteristic of this tumor is its capacity to secrete calcitonin (CT), which, measured in serum, sanctions suspicion of this pathology (5-8) leading to diagnostic studies to confirm CMT. For the preoperative diagnosis of thyroid nodules, ultrasound-guided fine-needle aspiration cytology (FNAC) is a useful and safe procedure; however, its sensitivity to exclude CMT is low (9-15). In 2015, a meta-analysis of 15 studies (16) found that the accuracy of FNAC in diagnosing CMT was around 50%. For this reason, other studies have indicated that the measurement of calcitonin in the fine-needle lavage aspirate fluid of thyroid nodules (CT-guided FNAC), which have suspected medullary carcinoma, can significantly improve the accuracy in the diagnosis of MTC (17 -19). Therefore, clinical practice guidelines recommend its determination in patients with suspected MTC (1,2). The diagnostic importance of pre-surgical medullary carcinoma lies mainly in two points: first, it changes the surgical approach of the patients, and second, it allows one to rule out associated pathologies such as hyperparathyroidism and pheochromocytoma, which are associated when the entity is hereditary. The performance of CT-guided FNAC by the chemiluminescent (CL) method has been widely disseminated. However, to the best of our knowledge, to date there are no data available on the appropriate cut-off value of CT-guided FNAC with calcitonin electrochemiluminescence (ECL) immunometric assay method. As previously stated, it is of particular interest to determine the calcitonin cut-off point in needle washing by electrochemiluminescence method that allows diagnosing medullary carcinoma. Clarifying this point allows improving the approach to patients in whom medullary carcinoma is suspected. This work seeks to determine the cut-off point of CT-guided FNAC for the diagnosis of CMT with the ECL assay method.
Large Cell Neuroendocrine Carcinoma (LCNEC) is a rare and aggressive form of cancer that presents significant challenges regarding treatment options and prognosis. In this trial, the effectiveness of Atezolizumab in treating metastatic LCNEC was evaluated. Atezolizumab is an anti-PD-L1 antibody that has shown promising results in other types of cancer, such as small-cell lung Cancer and non-small-cell lung cancer. The trial aimed to assess the efficacy and safety of atezolizumab in combination with chemotherapy as a potential treatment option for treatment-naive patients with metastatic LCNEC The trial was conducted as an open-label, non-randomized study, comparing Atezolizumab plus platinum etoposide to platinum etoposide alone in patients with metastatic LCNEC.
Background: Colorectal neuroendocrine carcinomas (CRNECs) are highly aggressive tumours with poor prognosis and low incidence. To date, the genomic landscape and molecular pathway alterations have not been elucidated. Methods: Tissue sections and clinical information were collected as an in-house cohort (2010-2020). Large-scale genomic and genetic panels were applied to identify the genomic and genetic alterations of CRNEC. Through the depiction of the genomic landscape and transcriptome profile, we compared the difference between CRNEC and CR neuroendocrine tumours (CRNETs). Immunohistochemistry (IHC) staining and immunofluorescence (IF) staining were performed to confirm the genetic alterations.
Due to lacking of evidence on surveillance for gastric neuroendocrine carcinoma (G-NEC), this study aimed to determine the optimal postsurgical surveillance strategy for G-NEC patients and compare its cost-effectiveness with traditional surveillance strategies.
This is an open-label, multicenter, phase 2 study of lurbinectedin monotherapy in participants with advanced (metastatic and/or unresectable) solid tumors.
To assess the importance patients place on each of the attributes of value (i.e., outcomes, quality of life [QOL], cost, experience), and how these patients’ views differ depending on the stage of their therapy (pretreatment, preoperative therapy, post-operative, long-term surveillance, recurrence).
Patients with advanced gastrointestinal (GI) cancers are very often sarcopenic/malnourished at diagnosis (> 60% of cases) and at high risk of rapid clinical deterioration. These patients have important supportive care needs that represent a major challenge for improving treatment tolerance and patient survival and health-related quality of life (HRQoL). Malnutrition and sarcopenia (muscle wasting and dysfunction) are associated with an increased risk of death, complications from chemotherapy, infections, emergency procedures and hospitalizations, and increased costs of care. Therefore, malnutrition and sarcopenia represent a major clinical target in GI cancers. Interventions targeting malnutrition/sarcopenia should be implemented as early as possible in patients' pathways, these syndromes being reversible at early stages but not at late stages. A multidisciplinary assessment at diagnosis and therapeutic approach combining nutritional support and and adapted physical activity (APA) in addition to anticancer treatments should be systematically implemented in patients with advanced GI cancers. This type of intervention complies with the standards recommended by the National Cancer Institute (INCa) to promote the practice of physical activity during and after treatment in oncology.
PRECISION-NEC is a single-center, open-label, pilot feasibility study of molecularly defined subtypes of metastatic high-grade neuroendocrine carcinoma (HG-NEC). The hypothesis is that HG-NEC (excluding small cell carcinoma) can be segregated based on mutational analysis and that next generation sequencing (NGS)-based assignment of therapy is feasible and will potentially improve the outcomes.
To assess the efficacy and safety of Temozolomide for second-line treatment of Neuroendocrine Carcinomas progressing after first-line Platinum-based therapy.
This single-blind, randomized controlled trial studies how well inhaled essential oils work for common quality of life concerns in patients who are undergoing cancer treatment such as chemotherapy, targeted therapy, and/or immunotherapy given through the vein (intravenously). Aromatherapy using essential oils, such as ginger essential oil, German chamomile essential oil, and bergamot essential oil, may improve quality of life issues such as nausea, anxiety, loss of appetite, and fatigue in patients undergoing treatment for cancer.
