SUMMARY -When taking diff erent drugs, their possible side eff ects on the skin should be considered, including skin reactions connected to photosensitivity. Th is photosensitivity caused by drugs can appear as phototoxic reactions (which occur more often) or photoallergic reactions (which occur less often and include allergic mechanisms). Th e following drugs stand out as medications with a high photosensitivity potential: nonsteroidal anti-infl ammatory drugs (NSAIDs), cardiovascular drugs (such as amiodarone), phenothiazines (especially chlorpromazine), retinoids, antibiotics (sulfonamides, tetracyclines, especially demeclocycline and quinolones), etc. In recent years, photosensitive reactions to newer drugs have appeared, e.g., targeted anticancer therapies such as BRAF kinase inhibitors (vemurafenib, dabrafenib), EGFR inhibitors, VEGFR inhibitors, MEK inhibitors, Bcr-Abl tyrosine kinase inhibitors, etc. In patients taking drugs over a longer period of time (e.g., NSAIDs, cardiovascular drugs, etc.), a particular problem arises when an unrecognized drug-induced photosensitivity on the skin manifests in summer months. When taking patient histories, the physician/dermatovenereologist should bear in mind that any drug the patient is currently taking may be the cause of skin reactions. Th erefore, patients who use potentially photosensitive drugs and treatments on a long term basis should be warned of the possibility of these side eff ects on their skin and advised to avoid direct exposure to sunlight and to use adequate photoprotection. If patients carefully protect themselves from the sun, it is often not necessary to stop treatments that include photosensitive drugs. If such reactions appear, anti-infl ammatory and antiallergic therapies should be introduced.
SUMMARY Although breast cancer (BC) occurs more often in older women, it is the most commonly diagnosed malignancy in women of childbearing age. Owing to the overall advancement of modern medicine and the growing global trend of delaying childbirth until later age, we find ever more younger women diagnosed and treated for BC who have not yet completed their family. Therefore, fertility preservation has emerged as a very important quality of life issue for young BC survivors. This paper reviews currently available options for fertility preservation in young women with early-stage BC and highlights the importance of a multidisciplinary approach to fertility preservation as a very important quality of life issue for young BC survivors. Pregnancy after BC treatment is considered not to be associated with an increased risk of BC recurrence; therefore, it should not be discouraged for those women who want to achieve pregnancy after oncologic treatment. Currently, it is recommended to delay pregnancy for at least 2 years after BC diagnosis, when the risk of recurrence is highest. However, BC patients of reproductive age should be informed about the potential negative effects of oncologic therapy on fertility, as well as on the fertility preservation options available, and if interested in fertility preservation, they should be promptly referred to a reproductive specialist. Early referral to a reproductive specialist is an important factor that increases the likelihood of successful fertility preservation. Embryo and mature oocyte cryopreservation are currently the only established fertility preservation methods but they require ovarian stimulation (OS), which delays initiation of chemotherapy for at least 2 weeks. Controlled OS does not seem to increase the risk of BC recurrence. Other fertility preservation methods (ovarian tissue cryopreservation, cryopreservation of immature oocytes and ovarian suppression with gonadotropin-releasing hormone agonists) do not require OS but are still considered to be experimental techniques for fertility preservation.
PURPOSE: Burnout is defined as a three-dimensional syndrome—emotional exhaustion (EE), depersonalization (DP), and reduced personal accomplishment (PA)—caused by chronic occupational stress. The aim of the current study was to investigate the prevalence of burnout among oncologists in Eastern Europe and to identify the contributing factors. METHODS: The study was conducted as an online survey between October 2017 and March 2018. Oncologists (including medical, radiation, clinical, and surgical oncologists) from 19 countries were invited to participate. The survey consisted of 30 questions, including the standardized burnout instrument, Maslach Burnout Inventory, and eight demographic questions. Burnout risk was scored according to the scoring manual for health care workers. RESULTS: The study included 637 oncologists. Overall, 28% were at low or intermediate risk and 72% were at high risk for burnout. Forty-four percent of participants were at high risk for EE, 28.7% for DP, and 47.3% for PA. EE risk was associated with female sex. DP risk was highest among clinical and radiation oncologists, whereas PA risk was positively correlated with years of service, percentage of cancer deaths, and availability of the number of oncologists. In multivariate logistic regression analysis, burnout was significantly associated with standardized cancer mortality and fewer years of practice. CONCLUSION: Burnout among oncologists in Eastern Europe is high, and younger oncologists are the most vulnerable group. Preventive measures should be taken to address this issue, which negatively affects optimal care delivery and poses a threat to oncologists’ health and well-being.
Management of young women with breast cancer is complex and has several particularities, one of which is fertility preservation, a very important quality of life issue for young breast cancer survivors. Chemotherapy can be gonadotoxic and signifi cantly reduce woman`s reproductive potential and cause premature ovarian insuffi ciency while endocrine therapy requires a delay of pregnancy and indirectly aff ects fertility. Therefore every woman of reproductive age diagnosed with breast cancer should be informed about potential gonadotoxic eff ect of cancer treatment, the risk of premature ovarian insuffi ciency and associated symptoms, available fertility preservation methods, delay of cancer treatment and chances of subsequent pregnancy. If interested in fertility preservation breast cancer patients should be referred as early as possible to a reproductive specialist to further discuss the risk of infertility and available fertility preservation options. Currently established methods for fertility preservation are embryo and oocyte cryopreservation, while ovarian tissue cryopreservation, cryopreservation of immature oocytes and ovarian suppression with gonadotropin-releasing hormone agonists are still considered experimental. The aim of this review is to highlight the importance of fertility preservation as an important quality of life issue for young breast cancer survivors.
Gastric cancer is related to high mortality rates and advanced disease stage at the time of diagnosis. Its carcinogenesis is extensively studied and is associated with genetic and epigenetic changes, changed the interaction between tumor and adjacent stromal cells, and changes in the microenvironment molecule status. NEDD9 affects different signaling proteins and pathways, apoptosis, adhesion, cell migration, and invasiveness. Connexin-43 also assists in intercellular communications and has several channel-independent functions. Aberrant expression of those two gap junction proteins plays an essential role in metastatic processes. Our scope was to detect the expression of connexin-43 and NEDD9 in epithelial and stromal gastric cancer compartments and its relation to tumor progression and lymph node metastases. Cancer tissue from 53 cases of node-negative and 55 cases of node-positive primary gastric carcinoma patients was analyzed for connexin-43 and NEDD9 expression by immunohistochemical assay, and the results were correlated with the remaining clinical and pathological findings and survival. In our cohort of patients with lymph node metastases, we detected higher expression of epithelial connexin-43 in the primary tumor and stromal connexin-43 expression correlated with both epithelial NEDD9 (rho=0.453) and stromal NEDD9 (rho=0.484). Higher epithelial connexin-43 and NEDD9 expression were associated with higher mortality (HR 1.54, 95% CI 1.01 -2.37, p=0.048). Epithelial connexin-43 expression, both epithelial and stromal NEDD9 expression, T and N status were all independently associated with shorter survival. In summary, our findings suggest that increased expression of both epithelial and stromal NEDD9 and epithelial connexin-43 could potentially be used as prognostic gastric cancer biomarkers.
Meningiomas are among the most common primary brain tumors. There is a growing need for novel ways of differentiating between benign (World Health Organization [WHO] grade I) and atypical (WHO grade II) meningiomas as well as for novel markers of the tumor's future behavior. A difference between glucose metabolism in atypical and benign meningiomas is well known. However, a significant correlation between the systemic metabolic status of the patient and the meningioma WHO grade has not yet been established. Our aim was to compare the WHO grades of intracranial meningiomas with the patient's HbA1c levels as a more reliable marker of the chronic systemic metabolic status than the fasting blood glucose value, which is usually looked at. We retrospectively analyzed 15 patients and compared their meningioma WHO grade with their preoperative HbA1c values. Our results show that patients with benign intracranial meningiomas have significantly lower HbA1c value. Conversely, patients with atypical intracranial meningiomas have higher HbA1c values. Furthermore, we showed that the proliferation factor Ki67 was statistically strongly correlated with the HbA1c value (p < .001. These results imply a possible positive correlation between meningioma cell proliferation and the chronic systemic glycemia. Further research in this area could not only lead to better understanding of meningiomas but could have significant clinical application.
