Background: Supportive care alone cannot be indicated for cancers for which established standard therapy exists unless there is a specific reason. Due to the refusal of standard therapy by the patient after proper explanation of the therapy, we experienced a long-term follow-up of >10 years with supportive care alone in an epidermal growth factor receptor (EGFR) mutated lung cancer patient.
Case: A 70-year-old woman was referred due to the right lung with some ground glass opacities (GGOs). One of the GGOs which was resected in another hospital had been confirmed to be EGFR mutation-positive lung adenocarcinoma. Although EGFR-tyrosine kinase inhibitor (TKI) was explained to be the standard therapy, the patient refused receiving the therapy and wished to follow up imaging of the remaining GGOs. During the follow-up period of 13 years, the each GGO showed a gradual increase. The doubling time of the largest GGO and that of serum carcinoembryonic antigen was > 2,000 days, respectively.
Conclusion: Although very rare, some of EGFR mutated lung adenocarcinoma might have a very slow progression. Clinical course of this patient provides useful information to the clinical practice of future patients who may have similar clinical courses.

Background: Immunotherapy by using immune checkpoint inhibitors (ICIs) heralded a new era in the treatment of patients with advanced triple-negative breast cancer (TNBC). Nevertheless, in a substantial proportion of TNBC patients, the clinical outcomes of ICIs treatment remain unpredict-able and proper bio-markers to identify tumors sensitive to immunotherapy are urgently needed. Currently, the most clinically relevant bio-markers used to predict efficacy of ICIs in patients with advanced TNBC remain the immunohistochemical analysis of programmed death-ligand 1 (PD-L1) expression, the assessment of tumor infiltrating lymphocytes (TILs) present in the tumor microenvironment (TME), and the evaluation of the tumor mutational burden (TMB). Emerging bio-markers related to activation of the transforming growth factor beta signaling pathway, the discoidin domain receptor 1, and thrombospondin-1 as well as other cellular and molecular factors present within TME, have the potential to be utilized as predictors of response to ICIs in the future.
Purpose: In this review, we summarize the current knowledge of mechanisms regulating PD-L1 expression, of the predictive value of TILs as well as of associated cellular and molecular components present in the TME in TNBC. Furthermore, TMB and emerging bio-markers with potential value in predicting efficacy of ICIs are discussed, and new therapeutic strategies will be outlined.

Background: Waldenström macroglobulinemia (WM) is a lymphoplasmocytic lymphoma with immunoglobulin M monoclonal protein. The incidence of this disease is very low (0.4/100,000), so that this disease can be regarded as an orphan's disease. It means that new drugs are often tested and registered for more frequent diseases.
Purpose: In this review we will focus on the efficacy of the new drugs for WM.
Results: The current treatment options for symptomatic WM patients include alkylating agent cyclophosphamide and anti-CD20 monoclonal antibodies. Therapy with rituximab and bendamustin resulted in longer therapeutic response then therapy with rituximab, cyclophosphamide and dexamethasone. Many drugs, used in multiple myeloma (MM), shoved promising results in WM patients. Bortezomib is effective in WM, but its neurotoxicity is higher in WM than in MM patients. Therefore, new proteasome inhibitors, carfilzomib and ixazomib, are better tolerated as documented in several studies. New types of antiCD20 antibody (obinutuzumab) can be used in patients with rituximab intolerance. in five of our patients with WM, obinutuzumab and bendamustin reached deeper responses than therapies administered in previous lines of therapy. Oral Bruton tyrosine kinase (BTK) inhibitor ibrutinib alone and in combination with rituximab have extended the treatment options for WM patients. New BTK inhibitors (e. g. acalabrutinib, zanubrutinib, and vecabrutinib) were tested and their lower toxicity (atrial fibrillation) was documented. Moreover, the BCL2 inhibitor venetoclax is newly tested.
Conclusion: New antiCD20 antibody (obinutuzumab) is of advantage in patients with WM with rituximab intolerance as well as bendamustin and new proteasome inhibitors (ixazomib and carfilzomib) or new BTK inhibitors with lower cardiotoxicity. Many of the abovementioned drugs do not have official registration for WM and can be administrated with the consent of the health care provider only. Thus, this work brings evidence of their efficacy.

Background: Brain tumors are a heterogeneous group of malignancies characterized by inter- and intratumoral heterogeneity. Among them, the most aggressive and, despite advances in medicine, still incurable remains glioblastoma. One of the reasons is the high recurrence rate of the disease and resistance to temozolomide, a golden standard in chemotherapy of brain tumors. Therefore, mapping the pathways responsible for tumorigenesis at the transcriptional level may help to determine the causes and aggressive behavior among different glial tumors.
Patients and methods: Biopsies from patients with astrocytoma (N = 6), glioblastoma (N = 22), and meningioma (N = 14) were included in the sample set. A control group consisted of RNA isolated from healthy human brain (N = 3). The reverse-transcribed cDNAs were analyzed using the Human Cancer PathwayFinder™ real-time PCR Array in a 96-well format. The expression of 84 genes belonging to 9 signaling pathways (angiogenesis, apoptosis, cell cycle and senescence, DNA damage and repair, epithelial-to-mesenchymal transition, hypoxia, overall metabolism, and telomere dynamics) was determined for each sample.
Results: By determining the relative expression of selected genes, we characterized the transcriptomic profile of individual brain malignancies in the context of signaling pathways involved in tumorigenesis. We observed deregulation in 50, 52.4 and 53.6% % of the genes in glioblastomas, meningiomas and astrocytomas, respectively. The most pronounced changes with statistical significance compared to control were observed in the genes associated with epithelial-to-mesenchymal transition (CDH2, FOXC2, GSC, SNAI2, and SOX10), cellular senescence (BMI1, ETS2, MAP2K1, and SOD1), DNA repair (DDB2, ERCC3, GADD45G, and LIG4), and dynamic of telomeres (TEP1, TERF2IP, TNKS, and TNKS2).
Conclusion: Based on the obtained data, we can conclude that individual diagnoses differ in transcriptomic profile. An individual molecular approach is therefore necessary in order to provide comprehensive and targeted therapy on multiple metabolic pathways in the diagnosis of brain tumors.

Background: Many experimental and clinical studies are conducted to investigate the effects of various applications of botulinum toxin (BTx) in the treatment of radiation related side effects. There are no studies that show clear results about the positive and negative effects of its active clinical use in the long run, and discussions are ongoing. In addition, there is a need for various researches about how BTx can be used and how long it can be used, and the side effects it may cause. BTx-A, which is one of the options in the treatment of side effects that will occur due to radiotherapy, is an effective and safe option. Applying BTx injection to the right place with specific injection methods increases the effectiveness and safety of the treatment.
Purpose: It has been investigated whether BTx will be a potential tool to perfect the esthetic and functional results in reducing the chronic side effects associated with radiotherapy.

Background: Recent developments regarding the contribution of microRNAs to tumor angiogenesis and the oncogenic effects of microRNAs point to their potential role in breast cancer angiogenesis. Tumor-derived exosomes are considered a rich source of microRNAs that can regulate the function of other cells in the tumor microenvironment, including vascular endothelial cells. This study analyzes the effect of tamoxifen chemotherapy on the expression of a key microRNA, miR-329, and introduces a regulatory link between this microRNA and the KDM1A gene associated with the vascular endothelial growth factor (VEGF) messaging pathway.
Materials and methods: MCF-7 breast cancer cells were purchased and cultured in a complete culture medium. These cells were treated with tamoxifen and then their exosomes were extracted from the culture medium. The RNAs of the exosomes were isolated and the expression of miR-329, VEGF, and KDM1A genes in the exosomes was investigated using the real-time polymerase chain reaction (PCR) method.
Results: The results of this study showed that tamoxifen treatment increased the expression of miR-329 in exosomes derived from MCF-7 cancer cells. The expression of KDM1A and VEGF genes in drug-treated cell exosomes is downregulated.
Conclusion: The results of this experiment demonstrated that the treatment of breast cancer cells with tamoxifen reduces the expression of VEGF and KDM1A by increasing miR-329. The treatment therefore reduces angiogenesis, and thus its anti-tumor effects are applied.

Background: Cancer mortality has doubled in India, a lower and middle-income country, from 1990 to 2016, depicting the ever-increasing burden of non-communicable disease. Karnataka, situated in the south of India, is one of the states with a rich medical college and hospital milieu. We present the status of cancer care across the state from the data collected by the investigators through public registries and personal communication to the concerned units to know the distribution of various services across the districts and give probable directives to improve on the present situation with emphasis on radiation therapy. This study may be taken as a bird's eye view of the situation across the country and form a basis based on which future planning of services and areas to emphasize on, may be considered.
Purpose: The establishment of a radiation therapy center holds the key to the establishment of comprehensive cancer care centers. The existing situation of such centers and the need and scope for inclusion and expansion of cancer units is presented in this article.

Background: Osteomas of the paranasal sinuses occur rarely in the pediatric population, we find only a few reference of symptomatic osteomas in the literature. Opinions on the indication for surgical treatment are controversial.
Case: The authors present a case of symptomatic osteoma of the right ethoimoidal sinus in a 12-year-old boy, who was treated surgically, with endoscopic endonasal approach. The symptomatology, diagnosis and therapy of these tumors in the pediatric patient are discussed.
Conclusion: Osteomas of the paranasal sinuses are slow-growing benign lesions. Symptomatic osteomas can grow expansively and cause serious complications. The treatment of osteoma is surgical and the endoscopic approach offers the possibility of removal with cosmetic benefits.

Background: Myeloma cells, occupying a bone marrow niche, are influenced not only by neighbouring stroma cells but also by signals from the axons of sympathetic nervous system. The nervous system is directly involved in the process of myeloma progression. Among other cancers, patients with myeloma suffer the most difficult distress generating intensive adrenergic signals, causing its further progression. There is a question arising from these facts regarding whether psychological interventions, modulating a function of the nervous system, can further improve outcomes of myeloma treatments. We focus on interactions between myeloma cells and the nervous system.
Patients and methods: Twelve patients with monoclonal gamapathy of indetermined significance (MGUS) or myeloma have participated in this study; eight in the interventional arm with the intervention of forgiveness therapy and four in the control arm. The patients were in various phases of their treatment, from active observation to immuno-chemotherapy and autologous stem cell transplant. Two major types of parameters were measured during the intervention: parameters of the activity of the disease (MGUS or myeloma) and psycho-neuro-immunological parameters of the patient, such as psychological depression, anxiety, and anger by the validated test PROMIS), as well as activity of the autonomic nervous system by heart rate variability, and immune profile by flow cytometry of peripheral blood.
Results: Patients who completed the forgiveness intervention showed improvement of depression, anxiety, and anger measured by PROMIS above population average, significant expansion of physiological plasma cells CD138+38+ (P = 0.04), B memory lymphocytes CD27+ (P = 0.02), and dendritic plasmacytoid cells CD123+ (P = 0.03). Parameters of heart rate variability such as parasympatic nervous system (PNS) index, sympatic nervous system (SNS) index, stress index, standard deviation of NN intervals (SDNN) and root mean square of the successive differences (RMSSD) had improved in a majority of patients.
Conclusion: An intervention centered on forgiveness therapy was able to improve distress, reduce adrenergic signals in the autonomic nervous system, and restore parameters of the immune profile of patients with plasma cell dyscrasia who suffered from chronic stress caused by repressed anger and unforgiveness. Integrative treatment of myeloma can improve the quality of life of patients and thus affect the efficiency of immuno-chemotherapy. New randomised trials are warranted to test the integrative treatment of myeloma that might be able to improve overall survival.

The nervous system is directly involved in the process of myeloma progression. Among other cancers, patients with myeloma suffer the most difficult distress generating intensive adrenergic signals, causing its further progression. There is a question arising from these facts regarding whether psychological interventions, modulating a function of the nervous system, can further improve outcomes of myeloma treatments.
