The role of positron computed tomography (PET/CT) in lung cancer staging
Hell J Nucl Med. 2023 May-Aug;26 Suppl:22-29.ABSTRACTLung cancer is the leading cause of cancer-related mortalities with the rate of incidence reaching about 1.5 million cases per year worldwide. Approximately 350 people die each day from lung cancer in USA-nearly 2.5 times more than the number of people who die from colorectal cancer (CRC), which is the second leading cause of cancer death overall. In 2023, an estimated 238,340 people (117,550 men and 120,790 women) will be diagnosed with lung cancer, and 127,070 people will die from the disease. Although approximately 80% of lung cancers are caused by cigarette smoking, ...

The progress in multiple myeloma
Hell J Nucl Med. 2023 May-Aug;26 Suppl:30-35.ABSTRACTMultiple myeloma (MM) is a neoplastic disease characterized by the proliferation of clonal plasma cells. This disease arises from an initial asymptomatic stage known as monoclonal gammopathy of unknown significance (MGUS). The clinical phenotype that lies between MGUS and MM is commonly known as smoldering multiple myeloma (SMM). In individuals with MGUS and SMM, the risk of progression to MM persists constantly. In MGUS, the progression rate to MM or a related malignancy is around 1% per year, while in SMM, the progression rate to MM is approximately 10% per year. Recen...

PET/CT: Clinical role in lymphomas
Hell J Nucl Med. 2023 May-Aug;26 Suppl:36-37.ABSTRACT18F-FDG PET/CT is the imaging modality of choice for the accurate initial staging of most lymphomas. Hodgkin's, Diffuse Large B-cell and follicular lymphomas show avid FDG uptake, while a minority of Non-Hodgkin lymphoma subtypes namely MALT, marginal and small lymphocytic lymphoma demonstrate low or moderate avidity. As a rule of thumb, indolent lymphomas show lower FDG activity than aggressive ones. PET/CT has increased sensitivity in the detection of nodal involvement even in small or normal-sized nodes. It shows higher sensitivity than CT in the detection of extra-no...

< sup > 18 < /sup > F-FDG PET/CT in monoclonal plasma cell disorders
Hell J Nucl Med. 2023 May-Aug;26 Suppl:38-41.ABSTRACTPlasma cell disorders are a heterogeneous group caused by the monoclonal proliferation of lymphoplasmacytic cells in the bone marrow. Multiple Myeloma (MM) is the most serious and prevalent plasma cell dyscrasia, with a median age of onset of 60 years.MM displays significant genetic, biological and clinical heterogeneity with subsequent imaging heterogeneity, evident in contemporary imaging modalities (PET/CT and MRI). Evidence suggests that MM is always preceded by precursor stages of monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myel...

Theranostic in Nuclear Medicine - The paradigm of NET
Hell J Nucl Med. 2023 May-Aug;26 Suppl:42-43.ABSTRACTTheranostics is an emerging field in medicine that combines diagnostics and therapeutics into a single approach. Overall, theranostics represents a promising paradigm for personalized medicine, as it allows for targeted and precise treatment based on individual patient characteristics. In nuclear medicine, theranostics involves the use of radiopharmaceuticals that have both diagnostic and therapeutic properties. Moreover, theranostics in nuclear medicine offers several advantages over traditional cancer treatments. Unlike radiotherapy, in nuclear medicine the therapy is ...

Biomarkers in neuroendocrine neoplasms
Hell J Nucl Med. 2023 May-Aug;26 Suppl:44-48.ABSTRACTNeuroendocrine tumors are a heterogenous group of rare neoplasms with different morphological features, immunophenotype, molecular profile, and clinical presentation. They can derive from any neuroendocrine cell throughout the body, but the majority of NENs is developed in the gastrointestinal tract. They can be divided into two groups, based on hormone secretion, functioning and non-functioning NENs. The first group is characterised from the secretion of specific substances, defining the clinical manifestations. Functional NENs can be divided into carcinoid tumors, with...

Current role of Nuclear Medicine in the diagnosis and therapy of gastroenteropancreatic neuroendocrine tumors (GEP-NETs)
Hell J Nucl Med. 2023 May-Aug;26 Suppl:49-51.ABSTRACTNeuroendocrine tumors (NETs), are heterogenic neoplasms that arise from the disseminated endocrine cell system, primarily from gastroenteropancreatic (GEP) organs. Nuclear Medicine has a central role in both diagnosis and treatment of GEP-NETs. Somatostatin receptor scintigraphy (SRS) is still performed with SPECT/CT in case that PET/CT is not available but numerous studies have demonstrated the superior diagnostic accuracy of the latter for GEP-NETs. 68Ga -Dota peptide PET/CT (SSA-PET/CT) has high sensitivity, specificity and accuracy (86%-100%) and is recommended for t...

Carcinoid syndrome-Symptoms and therapeutic approaches
Hell J Nucl Med. 2023 May-Aug;26 Suppl:52-56.ABSTRACTThe carcinoid syndrome (CS) is a constellation of symptoms attributed to hypersecretion of amines, prostaglandins and polypeptides. The cardinal symptoms of CS are flushing, diarrhea and bronchospasm; however, CS may present with various symptoms and signs, as: Skin: cutaneous flushes, cyanosis, pellagra, Gastrointestinal: diarrhea, nausea, abdominal cramps, vomiting, Heart: tricuspid and pulmonic valve thickening causing right heart failure, edema, Respiratory: wheezing, dyspnea.PMID:37658565 (Source: Hellenic Journal of Nuclear Medicine)

Changes in the concept and practice of radioembolization (SIRT)
Hell J Nucl Med. 2023 May-Aug;26 Suppl:57-59.ABSTRACTThe experience gained through the practice of radioembolization (SIRT) results in improvement of clinical outcomes. Improved outcomes are a prerequisite for the clinicians to reffer patients for SIRT. In recent years there are some critical changes in the concept and practice of SIRT that also contribute to the improvement of clinical outcomes, beyond the experience of the center performing SIRT. Two of them are dosimetry and a trend toward more focused therapies in the form of radiation lobectomy or segmentectomy.PMID:37658566 (Source: Hellenic Journal of Nuclear Medicine)

Management of pediatric papillary thyroid cancer
Hell J Nucl Med. 2023 May-Aug;26 Suppl:60-64.ABSTRACTPapillary thyroid carcinoma (PTC) originates from the follicular cell of the thyroid gland. PTC is a rare cancer and usually develops in pre-existing thyroid nodules, which are not common in children. PTC is often multifocal and bilateral. Low-risk subtypes such as classic PTC and follicular variant account for the majority of PTC, while high-risk histologic subtypes such as tall cell variant, diffuse sclerosing variant and poorly differentiated thyroid cancer occur more rarely in children. It is worth noting that the size of the thyroid in children is smaller compared t...

Radioiodine refractory differentiated thyroid cancer
Hell J Nucl Med. 2023 May-Aug;26 Suppl:65-68.ABSTRACTDifferentiated thyroid cancer is composed of papillary (85%), follicular (13%) with their subtypes and anaplastic (<2%) thyroid cancer, derived from follicular dedifferentiation. In the majority of cases (85%), treatment is succeeded with thyroxine suppression and radioiodine ablation. However, there is a small percentage of patients presenting with local recurrence or metastases during follow up. In such cases, reoperation and radioiodine treatment are the treatments of choice. 10% of the aforementioned patients appear resistance to radioiodine treatment and they are...

Recent advances in breast cancer treatment
Hell J Nucl Med. 2023 May-Aug;26 Suppl:83-84.ABSTRACTBreast cancer treatment is determined by the molecular subtype both in the early stage and the advanced disease. While there is clear benefit from adjuvant systemic treatment for patients with early-stage triple negative and HER2 positive breast cancer, it was unclear in the past which patient with luminal breast cancer needs adjuvant chemotherapy. As a result, we used to overtreat or undertreat patients. In the era of personalized treatment, genomic panels have become as or more important than the anatomic extent of disease to define prognosis in luminal breast cancer. ...

PET/CT: Role in staging, in follow-up and in the evaluation of disease recurrence in gynecologic cancer
Hell J Nucl Med. 2023 May-Aug;26 Suppl:85.ABSTRACT18F-FDG PET/CT may facilitate improved diagnosis and treatment in gynecological fields. This method provides pretreatment prognostic information concerning the aggressiveness of tumors which may contribute to optimizing and individualizing patient therapy. Although 18F-FDG PET/CT has a limited role for local staging of primary cancer, it has an important role in staging, as it aids particularly in identifying the involvement of lymph nodes and distant metastases throughout the whole body in a single examination in patients with advanced-stage disease and also in restaging a...
