[Gastrointestinal stromal tumors (GIST)]. / Gastrointestinale Stromatumoren (GIST).

Gastrointestinal stromal tumors (GIST) are rare tumors with a varying malignancy potential, most frequently located in the stomach and the small intestine. The median age at diagnosis is around 65 years. Standard treatment of localized disease is complete surgical resection. A GIST is generally resistant to conventional chemotherapy. Most GISTs harbor tyrosine kinase activating mutations in either the KIT or PDGFRA proto-oncogene. The standard treatment of locally advanced and metastatic GIST with such mutations is the tyrosine kinase inhibitor imatinib. In cases of progressive disease after successive treatment with imatinib, sunitinib, and regorafenib, a fourth-line therapy with ripretinib was recently approved. Approved in 2020, avapritinib is the first effective targeted therapy for advanced stage GIST harboring an imatinib-resistant PDGFRA D842V mutation.

Advances in the Treatment of Relapsed and Refractory Multiple Myeloma in Patients with Renal Insufficiency: Novel Agents, Immunotherapies and Beyond.

BACKGROUND: Renal insufficiency is one of the most frequent complications in multiple myeloma. The incidence of renal insufficiency in patients with multiple myeloma ranges from 20% to 50%. Renal impairment in patients with multiple myeloma results primarily from the toxic effects of monoclonal light chains on the kidneys. Dehydration, hypercalcemia, hyperuricemia, the application of nephrotoxic NSARs, antibiotics, contrast agents, etc., all play a major role in the deterioration of renal function in patients with multiple myeloma. The diagnosis and treatment of these patients use an interdisciplinary approach in consultation with hematologist-oncologists, radiologists, nephrologists and intensive care specialists. Using new drugs in the treatment of patients with refractory/relapsed multiple myeloma and renal insufficiency markedly improves progression-free survival and overall survival in these patients. CONCLUSIONS: New drugs have helped to widen the treatment options available for patients with renal impairment and refractory/relapsed multiple myeloma, since dose adjustments are unnecessary with carfilzomib as well as with panobinostat, elotuzumab, pomalidomide or daratumumab in patients with renal impairment. Several new substances for the treatment of refractory/relapsed multiple myeloma have been approved in the meantime, including belantamab mafodotin, selinexor, melflufen, venetoclax, CAR T-cell therapy and checkpoint inhibitors. Ongoing studies are investigating their administration in patients with renal impairment.

LUMBAR SPINE SYNOVIAL CYST: A CASE SERIES REPORT AND REVIEW OF SURGICAL STRATEGIES.

Lumbar spine synovial cysts are benign growths adjoining the facet joints that may induce low back pain, lumbar radiculopathy and neurological deficit. However, they are not well defined concerning their origin, cause and pathology, as well as available treatment strategies. The scope of different surgical procedures includes image-guided epidural steroid injection, direct cyst puncture by percutaneous epidural needle, spinal canal decompression and cyst resection, and spinal bone fusion with/without instrumentation. Hereby, we report institutional experience and discuss surgical strategies of lumbar spine synovial cyst treatment. Presenting symptoms, imaging findings and outcomes were retrospectively analyzed in 15 patients with lumbar spine synovial cyst, operated on during a one-year period. The leading presenting symptom was lumbar radicular pain, while the most commonly involved vertebral level was L5-S1. In a great majority of patients, a single-level interlaminectomy and cyst resection were performed. Most patients recovered without postoperative neurological and functional deficit, as well as surgery-related complications. No poor outcome was noticed in our series. Concerning our results and literature review, the optimal management for patients with symptomatic lumbar synovial cyst has to be highly personalized, which is essential to achieve a favorable outcome. Nonetheless, the best treatment strategy has yet to be affirmed.

Analgesic Effect - Comparison of Paracetamol Administered Intermittently and Through Patient-Controlled Analgesia Pump after Lumbar Discectomy: a Prospective Clinical Study.

Lumbar discectomy is the most common surgical treatment for intervertebral disc extrusion. Postoperative pain is a common clinical problem that greatly affects the length of hospitalization, functional status and patient quality of life. Th e aim of this study was to compare the postoperative analgesic effi cacy of paracetamol administered intermittently and through patient-controlled analgesia (PCA) pump following single level lumbar discectomy. Patients who underwent elective lumbar discectomy of intervertebral disc extrusion at the L4-L5 level diagnosed by magnetic resonance of the lumbosacral spine were included in the study. Pain was assessed at regular intervals for 48 hours through a shortened version of McGill pain questionnaire translated in the Croatian language. When pain was monitored as a summarized variable for each measurement, PCA group significantly stood up after 24 hours with better perception of pain compared to the intermittent group (c2-test, p<0.05). Adequate pain relief is an important aspect of postoperative care in spinal surgery patients. Postoperative use of paracetamol through PCA pump achieved better pain control and pain management versuspostoperative use of intermittent paracetamol analgesia after lumbar discectomy.

[Guidelines for interventional and invasive treatment in patients with mechanical back pain]. / Smjernice za intervencijske i invazivne postupke u bolesnika s mehanickom krizoboljom.

Back pain caused primarily by mechanical disorders is the most common type of back pain and it is usually found in young and middle-aged population, i.e. active population. This is why back pain is one of the most important public health problems. Treatment of pain syndrome affecting spine depends on a variety of factors and generally includes conservative and invasive methods. Relative indication for interventional and surgical procedures is long lasting back pain, the symptoms of which, predominantly pain, cause significant problems for the patient on performing everyday activities. Invasive/surgical treatment is applied after minimally 3 months of unsuccessful conservative treatment. Invasive and surgical procedures comprise a wide spectrum of interventions, from interventional and semi-interventional procedures, minimally invasive procedures to extensive, invasive operations that include instrumentation. The choice of intervention is based on clinical findings, duration and severity of pain and other symptoms, as well as on diagnostic reports. Despite recommendations based on the results of clinical studies, individual approach to each patient is the main principle of successful treatment.

[New techniques and prospects in invasive treatment in vertebrology]. / Novosti i perspektive u invazivnom lijecenju u vertebrologiji.

In this article authors outline new techniques and prospects in invasive treatment in vertebrology with emphasis on interventional and semi invasive procedures and minimally invasive surgery for lumbar disc herniation. They describe new approaches in neuroablative procedures for back pain treatment, in spinal fixation and in surgical treatment of scoliosis. Authors also report methods of great expectations which are not yet in use in our clinical practice but are promising like reconstruction of nucleus pulposus by autologous chondrocytes transplantation. New methods in cervical spine surgery are also discussed. The efficacy of each surgical method is pointed out. Apart from being informative, together with the corresponding article on patophysiology, magnetic resonance imaging and conservative treatment, these articles considering recent developments can be used as an aid in decision making when approaching these patients.

Cerebellar glioblastoma in the elderly--case report.

Cerebellar glioblastoma in the elderly is rare. Only 33 cases have been reported in the literature. We report on a 65-year-old male patient with cerebellar glioblastoma. Computed tomography scan revealed a posterior fossa tumor of 34 x 33 x 52 mm in size, with hydrocephalus. The patient presented with posterior fossa symptoms, ataxia, nausea and vomiting. He deteriorated rapidly and ventricular drainage was performed. When the patient's condition improved, suboccipital median craniectomy was performed and the tumor was removed. Postoperative treatment included radiotherapy and temozolomide chemotherapy.

Giant choroid plexus cyst as an accidental finding in an older man.

Choroid plexus cysts (CPC) are usually found at the end of the second trimester of pregnancy. Sometimes they can be accidentally and found on prenatal ultrasound examinations. Vast majority of CPC resolve spontaneously by 28th weeks gestation. In the older aged group the choroid plexus cysts are extremely rare pathomorphologic medical entity. Since they are almost always asymptomatic, they are therefore accidentally found on brain magnetic resonance (MR) or computed tomography (CT) scans. They are usually located in the lateral ventricles and measure around 2 cm in diameter. We present a case of a 75-year-old male with a giant choroid plexus cyst whose leading symptom was excruciating headache refractory to previous conservative therapy. He underwent surgery when osteoplastic craniotomy was performed with cyst fenestration and ablation. His recovery was uneventful with total regression of headaches. Reviewing the recent literature we did not find such a case considering the patients age and the size of the choroid plexus cyst.
