[Bone metastases - Current treatment strategy]

BOÉR Katalin, NÉMETH Zsuzsanna

[Bone is the most common site of metastatic disease in many solid tumours, mainly in breast, prostate and lung cancer. Patients with bone metastases are at risk for skeletal-related events such as bone pain, pathological fractures requiring surgery and/or radiation to bone lesions, hypercalcemia, and spinal cord compression. Skeletal-related events are major source of morbidity for cancer patients and may be associated with negative impact on quality of life and survival. Bisphosphonates inhibit osteoclast function and are widely used in the treatment of malignant bone disease, as preventive therapy against skeletal-related events. Recently, the NF-κappa B-ligand (RANKL)-mediated osteoclast activity and this pathway in bone metabolism became a prime target for the treatment of bone metastases. The fi rst drug targeting the RANK-RANKL pathway is denosumab, a fully monoclonal human antibody which binds to RANKL and inhibits osteoclast activity. Nowadays optimal treatment of bone metastases requires multidisciplinary management of patients including the administration of bone-modifying agents such bisphosphonates or denosumab. The use of bone-targeted agents is a valuable additional treatment in the fi ght against bone metastases and multiple, randomised trials have demonstrated the effectivity of these drugs in reducing skeletal morbidity caused by advanced cancer.]

[Treatment of osteoporotic vertebral compression fracture with PMMA augmented pedicle screw fixation]

PADÁNYI Csaba, MISIK Ferenc, PAPP Zoltán, VITANOVICS Dusan, BALOGH Attila, VERES Róbert, LIPÓTH László, BANCZEROWSKI Péter

[Background - Over the last few decades many innovative operation technique were developed due to the increase of porotic vertebral fractures. These new techniques aim to reach the required stability of the vertebral column. In case of significant instability, spinal canal stenosis or neural compression, decompressive intervention may be necessary, which results in further weakening of the column of the spine, the minimal invasive percutan vertebroplasty is not an adequate method to reach the required stability, that is why insertion of complementary pedicular screws is needed. Considering the limited screw-fixing ability of the porotic bone structure, with this new technique we are able to reach the appropriate stability of cement-augmented pedicle screws by dosing cement carefully through the screws into the vertebral body. We used this technique in our Institute in case of 12 patients and followed up the required stability and the severity of complications. Methods - Fifteen vertebral compression fractures of 12 patients were treated in our Institute. Using the classification proposed by Genant et al. we found that the severity of the vertebral compression was grade 3 in case of 13, while grade 2 in case of two fractures. The average follow up time of the patients was 22 months (12-39), during this period X-ray, CT and clinical control examinations were taken. During the surgery the involved segments were localised by using X-ray and after the exploration the canulated screws were put through the pedicles of the spine and the vertebral body was filled through the transpedicular screws with bone cement. Depending on the grade of the spinal canal stenosis, we made the decompression, vertebroplasty or corpectomy of the fractured vertebral body, and the replacement of the body. Finally the concerned segments were fixed by titanium rods. Results - In all cases the stenosis of spinal canal was resolved and the bone cement injected into the corpus resulted in adequated stability of the spine. In case of six patients we observed cement extravasation without any clinical signs, and by one patient - as a serious complication - pulmonary embolism. Neurological progression or screw loosening were not detected during the follow up period. Part of the patients had residual disability after the surgery due to their older ages and the problem of their rehabilitation process. Conclusion - After the right consideration of indications, age, general health condition and the chance of successful rehabilitation, the technique appears to be safe for the patients. With the use of this surgical method, the stability of the spine can be improved compared to the preoperative condition, the spinal canal stenosis can be solved and the neural structures can be decompressed. The severity of complications can be reduced by a precise surgical technique and the careful use of the injected cement. The indication of the surgical method needs to be considered in the light of the expected outcome and the rehabilitation.]

[Forgotten agent: raloxifene]

BENKŐ Ágota

[The largest group of the patients with osteoporosis is postmenopausal women characterized by a state of menopausal hormone deficiency which is results in accelerated bone loss. This increased bone resorption significantly elevates the risk of bone fractures including the most common type, i.e. vertebral fractures. In addition to the increased risk of fractures, estrogen deficiency affects other organs, thus, increasing the incidence of cardiovascular diseases, cancers, mood disorders and the symptoms of menopausal syndrome in women after menopause. In postmenopausal osteoporosis, the primary objective is to maintain the existing bone mass, a priority for the prevention and treatment of bone fractures. Hormone deficiency may be prevented by the administration of estrogen but the treatment may have adverse effects such as increased risk of endometrial cancer. An etiological therapy is desirable where the compound used for treatment exerts effects similar to that of estrogen to prevent postmenopausal bone loss as well as reduces the risk of cardiovascular disease without the stimulation of reproductive tissues.]

[The effect of biological therapy on generalised osteoporosis in patients with rheumatoid arthritis]

JUHÁSZ Péter

[In rheumatoid arthritis, the inflammation and damage of multiple joints can lead to generalised osteoporosis. This process is mostly mediaated by cells and cytokines that are also important for maintaining inflammation, by inhibiting bone formation as well as stimulating bone resorption. Data from the literature show that biological therapies that effectively decrease inflammation can also stimulate bone formation and inhibit bone resorption. This results in an increased bone density and bone protection, which is highly important to prevent subseqent fractures.]

[We conducted a multicentre, prospective, single cross-sectional, 12-month, open-label study for the assessment of treatment satisfaction using TSQM (Treatment Satisfaction Questionnaire for Medication) for zoledronic acid therapy used in patients with osteoporosis, who suffered minor traumatic fractures. PATIENTS AND METHODS - In total 1736 patients from 94 centers completed the study and filled in the TSQM questionnaire at both visit 1 and visit 2. TSQM is suitable for measuring the patient’s satisfaction with a treatment, by evaluating side-effects, efficacy and convenience of the treatment and the patient’s overall satisfaction rated on a scale of 0 to 100. RESULTS - Patients included in the study previously received a mean of 1.58 other therapies for osteoporosis and their case history included a mean of 1.24 fractures. This real-life study demonstrated that even one year of zoledronate treatment significantly (p<0.0001) improved the satisfaction of patients regarding efficacy (a mean change from a score of 56.15 to 70.89) as well as the occurrence of side-effects on a TSQM score. Regarding the convenience of treatment, the mean score increased from 62.96 to 79.34 (p<0.0001), whereas the overall treatment satisfaction changed from 59.3 to 75.48 by visit 2 (p<0.0001). CONCLUSIONS - Our study demonstrated beneficial TSQM results associated with zoledronic acid treatment, which is a basic requirement for appropriate adherence as well. ]

[Once again on adherence - Is it just fashionable or indeed a timely issue?]

VALKUSZ Zsuzsanna

[Nonadherence to pharmacological treat-ment in osteoporosis is a well-recognised problem not only in Hungary but all over the world. As in other chronic diseases, adherence to osteoporosis treatment is poor, which results in serious problems affecting patients as well as health care resources. Low adherence rates consistent-ly result in increased rates of fractures. Some approaches aimed to improve com-plience and persistence, such as extension of dosing intervals, might improve patients’ adherence to therapy. International clinical studies have demonstrated that the number of fractures cannot be reduced without suf-ficient adherence. Improving patient edu-cation, enhancing interactions between health care providers and patients, taking into account patients’ preferences and involving them in treatment decisions may all improve adherence.]

[Femoral neck fractures treated with DHLS screws - early results]

KOCSIS András, KÁDAS István, KÁDAS Dániel, HANGODY László

[In Hungary, the treatment approach for medial femoral neck fractures depends on the type of fracture and the overall condition of the patient. An obvious goal is to minimise the most common complications of the applied method, namely avascular necrosis of the head and redisplacement, while maintaining a low-risk and minimally invasive technique. Following the surgical method most commonly used in our country, we combined the double cannullated screws technique with the compressing HeadLess Screw System. This way we succeeded to achieve intraoperative compression, which provides intensified stability while retaining the principles of minimally invasive techniques.]
