Material and methods The study involved cancer patients treated at the Central Clinical Hospital of the Ministry the Interior in Warsaw in 2014. The questionnaire comprised basic demographic questions (socio-economic factors) and the AIS test estimating the level of illness acceptance in patients. Results For the group of patients in the research group, the arithmetic mean amounted to 27.56 points. The period of time that elapsed between the first cancer diagnosis and the start of the study did not influence the score of accepting illness. The acceptance of illness in patients diagnosed with metastases differed from the acceptance of illness by patients diagnosed with metastatic cancer. Females obtained the average of 29.59 in the AIS test, whereas the average in male patients was 26.17. The patients’ age did not impact the AIS test. There were no differences in the AIS test results between a group of people with secondary education and a group of people with higher education. There were no differences in the AIS test results between employed individuals versus pensioners. The inhabitants of cities were characterized by the highest degree of acceptance of their health condition. The lowest degree of acceptance of illness was observed in the group with the lowest average incomes. In the group of married individuals the average degree of acceptance of illness amounted to 27.37 points. The average degree of acceptance of illness in patients that declared themselves as single amounted to 25.75. Conclusions The average degree of acceptance of illness in the study group was 27.56 points, which is a relatively high level of acceptance of cancer. The main socio-economic factor, which influenced the AIS test results was whether metastases were diagnosed or not. There were no differences between patients in groups where the time that elapsed from the first diagnosis of cancer varied. There were no statistical differences between female and male patients as well as patients of different age. Additionally, the level of education and patients’ professional status did not impact in the AIS test results.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"53 1","pages":"261 - 265"},"PeriodicalIF":0.0,"publicationDate":"2015-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87496927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods Seventy-four patients of the Clinic of Oncology and Haematology at the Central Clinical Hospital (CSK) of the Ministry of Interior (MSW) in Warsaw were included in the study. The degree of adaptation to cancer was evaluated with the use of the mini-Mental Adjustment to Cancer (mini-MAC) scale. The individual subscales, i.e. fighting spirit, positive redefinition, helplessness-hopelessness, and anxious preoccupation, were collated with socio-demographic characteristics. Results Study findings indicate that: 1) tumour patients typically manifest behaviour that allows one to identify their adjustment to cancer; 2) in malignant tumour patients constructive behaviour prevails over destructive behaviour; 3) the helplessness-hopelessness response is more pronounced in men than women; 4) metastatic patients manifest stronger helplessness-hopelessness response than patients with locally limited tumours; 5) pensioners more often than people of working age adopt the helplessness-hopelessness strategy; and 6) patients with the shortest disease period manifest the strongest fighting spirit.

Incidence and severity of radiationinduced changes within the teeth individually vary depending on the patient's age, actual radiation dose, size of radiation exposure field, patient's general condition and additional risk factors. Inadequately managed treatment of caries may lead to loss of teeth, as well as prove instrumental in tangibly diminishing individual quality of life in patients. Furthermore, the need to have the teeth deemed unyielding or unsuitable for the application of conservative methods of treatment duly extracted is fraught for a patient with an extra hazard of developing osteoradionecrosis (ORN), while also increasing all attendant therapeutic expenditures.

In my work as a physician I met several patients with cancer in familiar history (e.g. colon cancer in the mother and grandmother) and despite the recommendations they avoid screening for the disease. In this year I was dealing with an adult male patient suffering because of a neuroendocrine tumour affecting duodenum with metastases to the liver. In 2013 due to the diagnosis of low-energy fractures, the hyperparathyroidism had been diagnosed in this man. The patient on account of the well-being neglected treatment and doctor visits. Since the origin of 2015 year he began to feel worse. He felt weakness and complained a loss of body weight despite the steady food supply. Above introduction concerning the patient from my practice prompted me to reflect on the relationship of individual components of familial syndromes associated with neuroendocrine tumours. Although the primary hyper-parathyroidism usually originates from benign adenoma without any relationship to syndromes associated with endocrine tumours, in some cases it can develop from the existing multiple endocrine neoplasia type 1 and 2a (MEN 1 and MEN 2a respectively) as well as be the result of hereditary hyperparathyroidism jaw tumour syndrome [1, 2]. There are also authors (e.g. Thakker, 2014) using names MEN2 for MEN2A, MEN3 for MEN2B and distinguish the type MEN4 for some form classified until recently to MEN1, but with a different genetic mutation. Abnormalities of CD-KN1B gene which in man is located on chromosome 12p13 are considered to be the cause of MEN4. Parathyroid ad-enoma, pituitary adenoma, reproduction organ tumours (e.g. testicular cancer, neuroendocrine cervical carcinoma), adrenal and renal tumours are classified as components of MEN4 syndrome [3]. There are no reports of any others familiar syndromes associated with neuroendocrine tumours and primary hyperparathyroidism. From written previously syndromes causing primary hyperparathyroid-ism MEN1 is the most frequent and the best known. Primary hyperparathyroidism is usually the first in medical history and the most common endocrynopathies in MEN1 [2]. Although incidence of MEN1 in patients diagnosed with primary hyperparathyroidism is estimated in range of 2–4%, the hyperparathyroidism reaches nearly 100% penetrance by the age of 50 years in MEN1 patients [2]. The others syndromes associated with neuroendocrine tumours carry even lower probability of primary hyper-parathyroidism e.g. in MEN2/MEN2a it is rarer. It occurs in 20–30% of patients, is also later …","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"4 1","pages":"343 - 344"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90539824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During EMT tumour cells acquire a mesenchymal phenotype that is responsible for their invasive activities. Consequently, Snail1 expression in colorectal cancer is usually associated with progression and metastasis. Some studies revealed that about 77% of colon cancer samples display Snail1 immunoreactivity both in activated fibroblasts and in carcinoma cells that have undergone EMT. Therefore, expression of this factor in the stroma may indicate how many cells possess the abilities to escape from the primary tumour mass, invade the basal lamina and colonise distant target organs. Blocking snail proteins activity has the potential to avert cancer cell metastasis by interfering with such cellular processes as remodelling of the actin cytoskeleton, migration and invasion, which are clearly associated with the aggressive phenotype of the disease. Moreover, the link between factors from the snail family and cancer stem cells suggests that inhibitory agents may also prove their potency as inhibitors of cancer recurrence.","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"37 1","pages":"265 - 270"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84483133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the recent years the number of new diagnoses has exceeded 16,500 per year. Published data regarding far-distant results of breast cancer treatment that take under consideration the provincial division of the country may not be representative of the therapeutic effects achieved in specific oncological centres. The goal of this article is to analyse far-distant therapeutic results in breast cancer patients treated at the Oncology Centre in Bydgoszcz in 2006. They were compared with data available for Kujawsko-Pomorskie Voivodeship and with all-Poland results. Material and methods A cohort of 667 breast cancer patients at Bydgoszcz Oncology Centre between Jan 1 and Dec 31, 2006 was studied. The majority of the studied group were patients in stage I (26.2%) and II (48.3%) according to the TNM staging system, 17.5% were in stage III, and 6.4% in stage IV. The 5-year survival and 5-year disease-free survival rates were calculated. Median observation time was 79 months. Results A total of 148 patients (22.2%) suffered a relapse. There were 168 (25.2%) deaths caused by primary disease. The 5-year survival probability was 0.761 ±0.017 and the five-year disease-free survival probability was 0.807 ±0.016. Median survival time was 76.4 months, and median disease-free survival was 19.4 months.

Any changes in sequence in this region can cause numerous pathologies and can also lead to tumour development. The most common changes reported in in the CDKN2A gene are the 148Ala/Thr in exon 2 and 500C>G and 540C>T in the 3'UTR region. They are suspected of having a great impact on cancer progression. Since the role of these sequence variants in the Polish population in the development of melanoma has not been confirmed, the importance of 3'UTR polymorphisms in the regulation of gene expression was tested. Material and methods First, genetic analysis in a group of 285 melanoma patients was performed and the obtained results were correlated with the clinical course of melanoma. Then vectors carrying 3'UTR sequence variants were prepared and the level expression of the reported gene was measured. Results Within this study no correlation between the presence of 148Ala/Thr polymorphism and cancer in the family was observed. There was a correlation between the presence of this polymorphism and breast cancer and melanoma in the same patient. There was no correlation between 500C>G polymorphism and tumour localisation, age of diagnosis, and type of cancer in patients’ family, but a correlation between the percentage of patients dying and the 500C>G variant was observed.

Retrospective studies have suggested that HPV-related HNSCCs are more frequently cured than those caused by tobacco. Current clinical trials focus on the reduction of treatment-related toxicity and the development of HPV-targeted therapies. New treatment strategies include: 1) dose reduction of radiotherapy, 2) the use of cetuximab instead of cisplatin for chemo-radiation 3) less invasive surgical options, i.e. trans-oral robotic surgery and trans-oral laser microlaryngoscopy, and 4) more specific treatment attempts, including immunotherapeutic strategies, thanks to increasing comprehension of the molecular background of HPV-related HNSCC. Whereas recently published data shed light on immune mechanisms, other studies have focused on specific vaccination against HPV-related HNSCC. A crucial problem is patient selection to the chosen bias.

The symptoms are highly unspecific and the small, flat CIS lesions can easily be missed, thus remaining unseen in standard white light cystoscopy. Photodynamic diagnosis (PDD) is recommended by the European Association of Urology (EAU) as a diagnostic procedure in cases of suspected CIS [1]. \u0000 \u0000A 58-year-old man visited the outpatient clinic complaining of symptoms of dysuria and occasional pain during micturition. The patient had been a smoker for 20 years, with no risk of exposure to chemical substances. The medical history did not indicate any haematuria or fever. Digital rectal examination found the prostate to be of proper density, with little enlargement and no other pathological findings. The preliminary diagnosis was set as lower urinary tract syndrome secondary to prostate enlargement. The patient was sent for creatinine assay, prostate specific antigen (PSA) assay, a urine test, and ultrasound examination of the kidneys, bladder, and prostate. He received a prescription for diclofenac, tamsulosin, and ciprofloxacin. \u0000 \u0000The next appointment in the outpatient clinic was set for two months later as a follow-up. During that visit, the patient reported two episodes of painless bleeding in his urine. The serum levels of creatinine and PSA were 0.9 and 1.2 ng/ml, respectively, and no abnormalities were observed in the results of the urine test. No pathological changes were observed by ultrasonography. After the treatment, the symptoms of dysuria were diminished. \u0000 \u0000In response to the presence of bleeding in the urine, the patient was sent for urethrocystoscopy, performed with short intravenous anaesthesia, and urinary cytology, which revealed the presence of pathological cells. On the basis of this result and that of the earlier ultrasonography, which indicated no bladder tumour symptoms, the patient was qualified for PDD. \u0000 \u0000Photodynamic diagnosis was performed after intravesical instillation of a photosensitiser (Hexvix®) 60 minutes before the procedure. A Wolf PDD system was used to observe the photodynamic effect. Although the white light cystoscopy revealed only one pathological lesion, 4 mm in diameter, on the front wall of the urinary bladder, the urinary bladder mucosa seemed otherwise unaffected by any pathological changes. After switching to PDD mode, three independent points were indicated by red flashes: one on the back wall (8 mm in diameter), one on the right wall (5 mm in diameter), and one on the left wall of the urinary bladder (5 mm in diameter) (photo). Tissue samples were taken from each of the suspicious lesions. Both the papillary tumour and the three lesions visible only in PDD were treated by transurethral resection of the bladder tumour (TURBT). After the operation, instillation of mitomycin C was performed. \u0000 \u0000The histopathological report revealed the papillary tumour from the front wall to be a high-grade non-muscle-invasive bladder cancer ","PeriodicalId":10652,"journal":{"name":"Contemporary Oncology","volume":"47 1","pages":"341 - 342"},"PeriodicalIF":0.0,"publicationDate":"2015-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84791984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
