Opis:
Background: Ovarian cancer is the fifth most common form of cancer in the world and is often asymptomatic in its early stages. Development of ovarian cancer-specific biomarkers for the early detection of disease could improve the current dismal survival rate. Evaluation of serum carbohydrate antigen 125 (CA125), alkaline phosphatase (ALP) and oxidative stress in ovarian carcinoma patients may improve the prognosis of the disease through earlier detection. Aim of the study: The aim of this study was to find the relative risk of ovarian cancer in patients screened for CA125, ALP, Nitric oxide (NO) and Malondialdehyde (MDA) as a marker for lipid peroxidation. Material and methods: 451 subjects with ovarian cancer were screened for serum CA125 levels using a chemiluminescence analyser, out of which 164 showed values above 21 U/ml. 80 subjects with higher values were further analysed for MDA and NO using spectrophotometry and AL P by fully automated chemistry analyser. Results: The selected 80 subjects with CA125 values above 74 U/ml had increased ALP, NO and MDA, also showing positive correlation amongst these parameters. Conclusions: Benefits of CA125 screening vary with age group according to blood CA125 levels. Enzyme ALP levels are elevated with higher values of CA125. MDA and NO indicate oxidative stress and increase as the ovarian marker values increase. Positive correlation amongst the parameters indicates a significant increase in oxidative stress in ovarian cancer. For women with various CA125 levels in different age groups, screening and treatment depends upon individual decision and clinical examination.

Opis:
Introduction: Early age at menarche and late age at last menstrual period, as well as other reproductive factors, may be the cause of development of some types of cancer concerning the female reproductive organs. It has been estimated that late menopause may be responsible for the occurrence of even 16% of cases of ovarian cancer in the population. The incidence of ovarian cancer is also higher among nulliparous women, and among those who rarely become pregnant. Objective: The objective of the study was analysis of the effect of reproductive factors on the risk of ovarian cancer. Methodology: The study covered healthy women, without the diagnosis of focal lesions in the ovaries, and women with the diagnosis of ovarian cancer. The study was conducted during the period from September 2007 – November 2011, and covered a total number of 1,346 women. Odds ratio was calculated for individual risk factors. Statistical analysis was performed by means of the statistical packages STATISTICA v8, GrafPad Instat v 3.00, Analyse-it v. 2.2, and Cytel Studio StatXact-8. Statistical hypothesis were verified on the level of significance p ≤ 0.05. Results: Among females who began menstruating by the age of 11, the risk of ovarian cancer was 1.6 higher than among those in whom the first period occurred at the age of over 13. Similarly, among women who menstruated at the age of over 55 the risk of development of ovarian cancer was 1.4 times higher. The age at which a woman delivered her first live baby is also of importance. In the group of women who gave birth at the age of over 35, the risk was elevated and remained on the level of OR=1.7; 95%CI 0.66-4.5, compared to those who bore the first baby under the age of 25. If the pregnancy was terminated with miscarriage, the risk of contracting ovarian cancer decreases, and was on the level of OR=0.8; 95%CI 0.53-1.28, compared to the women who have never been pregnant. Among patients who did not breastfeed their babies, ovarian cancer risk was 1.7 times higher, compared to those breastfeeding. Conclusion: Reproductive factors exert a significant effect of the risk of development of ovarian cancer.

Opis:
Inflammation plays a key role in epithelial ovarian cancer tumorigenesis and progression. The growth and progression of epithelial ovarian cancer may be due to local cytokine-induced immunosu-ppression, which may lead to an immunity impairment. Thus, cytokine antagonism may be an essential factor in the treatment of ovarian cancer. Based on the increased knowledge on the role of the immune system in ovarian cancer, major improvements are to be expected of immunotherapy based treatment of this disease. This article aims to summarize the current literature views on the evidence for a role for chronic inflammation with a specific focus on anti-inflammatory cytokines.

Introduction. A correct diet plays an important role in the prevention of malignant tumours. The risk of the disease may be reduced by introducing a number of changes to the daily diet. The most important changes concern the amount of fat in the diet, dietary fibre, antioxidants in the food and the reduction of substances having a significant impact on the development of malignant tumours. Objective. The aim of the study is to analyse the role of selected modifiable lifestyle factors affecting the development of ovarian cancer. Materials and method. The study covered healthy women and women with diagnosed ovarian cancer. A total of 850 women aged between 21–84 were studied. The study included women visiting the Gynaecology and Obstetrics Hospital of the University of Medical Sciences in Poznan, Poland, between 2011–2013. Patients recognized with malignant ovarian cancer were qualified into the study based on the histopathological examination of the material obtained during surgery. Results. Respondents who consumed fruit and vegetables several times a week have the odds ratio OR = 0.29 level; 95% CI 0.04–2.01 (p =.2085), compared to women not consuming fruit and vegetables at all. Consumption of 100 g of French fries and potato chips several times a week, results in a 2-fold increase in ovarian cancer. The OR for this group of women amounts to 2.06; 95% CI 0.53–7.99 (p=.2966). Conclusions. A diet rich in fruit and vegetables, including bulb vegetables, and grain products containing whole grains, should be introduced. It is recommended that the consumption of popular fast foods be eliminated.

Opis:
The paper presents current algorithms of surgical treatment of patients with ovarian cancer. At early clinical stages (FIGO stage I and II), the basic principle of surgical treatment is radical excision of malignant lesions within the pelvis and meticulous search for metastatic foci of tumour within the mid-abdomen and epigastrium. Therefore, mandatory procedures include omentectomy, multiple sampling of peritoneum (including diaphragmatic lining) and periaortal lymph nodes. In late-stage disease (FIGO stages III and IV), the main task is to remove all metastatic foci, both within the abdominal cavity and retroperitoneal space. In late-stage cases, surgery requires great expertise of both surgical, anesthetic and physiotherapy teams. Required are also precise surgical instruments, including argon bipolar coagulation, a reliable diathermy unit and a kit of self-retaining retractors. Extensive cytoreductive procedures are burdened by an elevated complication rate, therefore in selected cases preoperative (neoadjuvant) chemotherapy is used.
W artykule przedstawiono współczesne algorytmy postępowania chirurgicznego u chorych leczonych z powodu raka jajnika. We wczesnych stopniach zaawansowania klinicznego (I i II wg klasyfikacji FIGO) zasadą postępowania chirurgicznego jest nie tylko usunięcie zmian nowotworowych zlokalizowanych w miednicy mniejszej, lecz także dokładne sprawdzenie, czy nie ma ognisk nowotworu w śródbrzuszu i nadbrzuszu. Dlatego obligatoryjne jest wycięcie sieci, pobranie licznych wycinków z otrzewnej, w tym także przepony, oraz pobranie do badania węzłów przyaortalnych. W stopniach zaawansowanych (III i IV wg klasyfikacji FIGO) zasadniczym zadaniem jest usunięcie wszystkich ognisk przerzutowych zarówno z terenu jamy brzusznej, jak i przestrzeni zaotrzewnowej. Chirurgia w tych stopniach zaawansowania wymaga bardzo dużego doświadczenia zespołu zarówno chirurgów, jak i anestezjologów i rehabilitantów. Wymaga także użycia precyzyjnych narzędzi chirurgicznych, w tym: bimera argonowego, dobrej diatermii oraz zestawów haków samotrzymają-cych. Rozległe cytoredukcyjne operacje są obarczone większą liczbą powikłań i dlatego niekiedy stosowana jest przedoperacyjna (neoadiuwantowa) chemioterapia.

Opis:
Ovarian cancer is the most threatening cause of death among gynecologic malignancies and represents the fifth leading cause of death from all cancers for women. Research reveals that ovarian cancer patients exhibit significant immune responses against the tumor. In this review of the current literature chiefly the interaction of ovarian cancer tumor cells and the immune system is discussed. There is increasingly growing evidence that pro-inflammatory cytokines are involved in intricate complex of mechanisms responsible for tumorigenesis, and delicate balance between pro- and anti-inflammatory cytokines is critical for the antitumor host immune response.

Opis:
Due to late diagnosis, ovarian cancer is the most deadly gynecologic malignancy. Inflammation is one of the risk factors of ovarian cancer and the inflammatory response implicates all stages of tumorigenesis. The purpose of this study was to analyze the concentration of molecules, which can take part in malignant processes. We analyzed patients with ovarian cancer, with endometriosis and healthy controls. Thirty-seven analytes were measured in serum using BioPlex Pro Human Inflammation Panel. We were able to detect 28 of the proteins among the studied groups. We found a significant increase in 22 of the tested molecules (BAFF, Chitinase3-like 1, IFN-alpha2, IFN-beta, IFN-gamma, IFN-lambda2, IFN-lambda1, gp130, IL-2, IL-12 (p40), IL-11, IL-32, IL-35, MMP3, Osteocalcin, Pantraxin-3, sCD163, TNFRSF8, sIL-6Ralpha, STNF-R1, STNF-R2, and TSLP) in the ovarian cancer group in comparison to the healthy controls. Two of them (IL-20, MMP1) did not show significant differences between groups. Moreover, we identified decreased concentrations of APRIL and osteopontin in ovarian cancer vs. healthy controls. While this study is a preliminary report, we hope this will encourage a further use of multiplex analysis in ovarian cancer biomarker research.

Opis:
Hereditary causative factors are present in about 10% of ovarian cancer cases, mainly BRCA1 and BRCA2 mutations. Mean age of women developing hereditary ovarian cancer is about 10 years lower (42-45 years) than that of women with sporadic ovarian cancer (54 years). In both groups prognosis is similar. Most common histological type is serous adenocarcinoma. The paper presents a case of a 44-year-old woman, in the care of genetic outpatient clinic because of BRCA1 mutation. For the first time, the patient presented at the Centre of Oncology in Warsaw, Poland, in 2002, with results of biopsy of a breast lesion. Due to a positive family history, the patient entered of the Program of supervision of families burdened by high, genetically determined risk of malignant tumours, conducted by the Genetic Outpatient Clinic of the Institute. The patient was subjected to a regular follow-up at 6-months’ intervals. Five years after her first visit, in October 2007, transvaginal sonography revealed a small cystic lesion with endophytic excrescences in the left ovary, 3 cm in diameter, with concomitant increase of the Ca 125 level. Control study in December 2007 confirmed the presence of a cystic-solid tumour of the left ovary. The patient was qualified for surgical treatment. Surgery consisted in hysterectomy, adnexectomy, omentectomy, retroperitoneal lymphadenectomy and peritoneal biopsy. Microscopic studies of surgical specimens revealed urothelial adenocarcinoma G3. The patient was referred for paclitaxel- and carboplatin-based chemotherapy.
Około 10% przypadków raka jajnika związanych jest z czynnikami dziedzicznymi, głównie z mutacjami BRCA1 i BRCA2. Średnia wieku kobiet, u których wystąpił dziedziczny rak jajnika, jest mniej więcej o 10 lat niższa (42-45 lat) niż u kobiet z grupy, w której stwierdzono sporadycznego raka jajnika (54 lata). Rokowanie w obu grupach jest podobne. Najczęściej spotykanym typem histopatologicznym jest rak gruczołowy surowiczy. W niniejszej pracy przedstawiono przypadek 44-letniej kobiety będącej pod opieką poradni genetycznej z powodu stwierdzonej mutacji genu BRCA1. Pacjentka zgłosiła się po raz pierwszy do Centrum Onkologii - Instytutu w Warszawie w 2002 roku z wynikiem biopsji ze zmiany w piersi. Ze względu na obciążony wywiad rodzinny pacjentka została zakwalifikowana do Programu opieki nad rodzinami wysokiego, dziedzicznie uwarunkowanego ryzyka zachorowania na nowotwory złośliwe, realizowanego przez Poradnię Genetyczną w CO-I w Warszawie. Pacjentka została poddana regularnym badaniom, które odbywały się co 6 miesięcy. Po 5 latach od pierwszego badania, w październiku 2007 roku, w badaniu USG TV stwierdzono niewielką, trzycentymetrową torbielowatą zmianę z endofitycznymi wypustkami w prawym jajniku oraz jednoczesny wzrost poziomu Ca 125. Kontrolne badanie USG TV przeprowadzone w grudniu 2007 roku potwierdziło obecność podejrzanego tor-bielowato-litego guza prawego jajnika. Wobec podejrzenia raka jajnika pacjentka została zakwalifikowana do leczenia operacyjnego. Wykonano wycięcie macicy z przydatkami, sieci większej i węzłów chłonnych za-otrzewnowych oraz biopsję otrzewnej. Wynik materiału pooperacyjnego: rak gruczołowy urotelialny G3. Pacjentka została zakwalifikowana do chemioterapii uzupełniającej z zastosowaniem paklitakselu i karboplatyny.

Introduction and objective. The aim of the study was evaluation of the urban and rural differences in ovarian cancer patients’ characteristics at the moment of diagnosis. Materials and methods. The study comprised women with ovarian cancer diagnosed and treated in the Division of Gynecological Surgery of Poznan University of Medical Sciences between 2004–2011. The patients were divided into 3 groups based on their place of residence: 1) patients residing in large cities (over 50,000 people), 2) inhabitants of small towns (below 50,000 people), 3) women from rural areas. Results. Among the studied groups of patients no differences were found in the FIGO stage at diagnosis (p=0.453), histological grade of the tumour (p=0.916), histopathological types of ovarian neoplasms (p=0.431), median tumour volume (p=0.855), presence of fluid in the pouch of Douglas (p=0.872). Women with ovarian cancer residing in large cities had lower median parity (p=0.0005), higher education level status (p=0.0001), and experienced menarche at an earlier age (p=0.039). There were no differences in the use of oral contraception (p=0.93) and body mass index (p=0.23) between the women included in the study. Conclusions. There were no differences in advancement of ovarian cancer at the moment of diagnosis or in tumour type and size between women residing large cities, small towns and rural areas. Several ovarian cancer risk factors were more common among ovarian cancer patients living in urbanized areas.

Opis:
Neoplastic markers represent high molecular weight substances produced both by neoplastic and healthy cells in response to a developing tumor. A marker may also involve any assayable substance in tumor tissue which manifests immunoreactivity distinct from that in normal tissues. Neoplastic markers serve in the detection of the disease, monitoring of treatment efficacy and in the detection of a relapse. In the case of ovarian cancer, the most recognizable marker involves CA-125, an elevated level of which is detected in around 80% serous carcinomas andwhich increases as the disease progresses. Early stages of ovarian carcinomas are detected by estimation of HE4 (human epididymis protein). The Risk of Malignancy Index (RMI algorithm) is based on the estimation of the CA-125 level, transvaginal ultrasound examination and condition of menopause. Other algorithms used in ovarian carcinoma include OVA-1, based also on CA-125 level, menopausal status and on four proteomic markers, and ROMA (Risk of Ovarian Malignancy Algorithm), based on CA-125 and HE4. Other markers of less pronounced importance for ovarian carcinoma include: • CA-19-9 (antigen of gastrointestinal carcinoma) – of particular use in carcinomas of gastrointestinal tract, including pancreatic carcinoma but also mucous ovarian carcinoma; • CEA (carcinoembryonic antigen) – a marker of alimentary tract carcinomas, including colorectal carcinoma, gastric carcinoma but also mucous ovarian carcinoma; • CA-15-3 (MUC1) – the recognized marker of breast carcinoma, the concentration of which increases in advanced stages of ovarian carcinoma; • YKL-40 (glycoprotein of human cartilage) – allowing detection of early stages of ovarian carcinoma and its relapses; • kisspeptin (KiSS-1) – associated with the inhibition of metastases in clarocellular ovarian carcinoma; • HIF-1α (hypoxia-inducible factor-1α) – similarly to clusterin, linked to resistance to chemotherapy; • E-cadherin, SDF-1 and metadherin linked to the development of metastases; • enzymatic markers COX-1 and in particular COX-2 correlate with the progress of the disease while an increased COX-2 level indicates resistance to chemotherapy.
Markery nowotworowe są wielkocząsteczkowymi substancjami wytwarzanymi w odpowiedzi na rozwijający się nowotwór zarówno przez komórki nowotworowe, jak i komórki zdrowe. Markerem może być także substancja oznaczona w tkance guza, która wykazuje inną immunoreaktywność niż w tkankach zdrowych. Markery nowotworowe służą do wykrycia choroby, monitorowania skuteczności leczenia, a także wykrycia wznowy. Najbardziej uznanym markerem dla raka jajnika jest CA-125, którego podwyższone stężenie występuje w około 80% raków surowiczych i wzrasta wraz z zaawansowaniem choroby. Do wykrycia wczesnych stadiów raka jajnika stosuje się HE4 (human epididymis protein). Na wartości stężenia CA-125, badaniu przezpochwowym i stanie menopauzalnym oparty jest algorytm RMI (Risk of Malignancy Index). Innymi algorytmami stosowanymi w raku jajnika są OVA-1 (oparty również na wartości CA-125, stanie menopauzalnym i czterech markerach proteomicznych) oraz ROMA (Risk of Ovarian Malignancy Algorithm), włączający do badania wartość CA-125 i HE4. Markerami mającymi mniejsze znaczenie w raku jajnika są: • CA-19-9 (gastrointestinal cancer antigen) – stosowany w rakach przewodu pokarmowego (w tym raku trzustki), ale również w raku śluzowym jajnika; • CEA (carcinoembryonic antigen) – marker dla raków przewodu pokarmowego, w tym raka jelita grubego i żołądka, ale też raka śluzowego jajnika; • CA-15-3 (MUC1) – uznany marker dla raka piersi, którego stężenie wzrasta w zaawansowanych stadiach raka jajnika; • YKL-40 (ludzka chrząstkowa glikoproteina) – wykrywająca wczesne stadia raka jajnika i jego wznowy; • kisspeptyna (KiSS-1) – związana z hamowaniem przerzutowania w jasnokomórkowym raku jajnika; • HIF-1α (hypoxia-inducible factor-1α) – związany z opornością na leczenie chemiczne, podobnie jak klusteryna; • E-kadheryna, SDF-1 (stromal-derived factor-1) i metadheryna – związane są z przerzutowaniem; • markery enzymatyczne COX-1 i COX-2 – korelują z progresją choroby, a wzrost stężenia COX-2 świadczy o oporności na chemioterapię.

Opis:
Ovarian cancer is characterized by an extremely poor prognosis in women with an advanced stage of this carcinoma. In United States every year 20,000 women are diagnosed with ovarian cancer. It is the fifth most frequent cause of death from cancer in females and the most common cause of death for 15 years after diagnosis in women with stage III-IV tumors. Among ovarian neoplasms the most frequent are surface epithelial-stromal tumors. Moreover, non-epithelial ovarian tumors are distinguished. This group matters 10% of patients with diagnosed ovarian tumors. Due to a huge variety of ovarian tumors, the following work focuses mainly on the current clinical treatment of the epithelial ovarian cancer. The following paper summarizes current clinical treatment of epithelial ovarian cancer, including surgical procedure, chemo- and immunotherapy including modern therapeutic approaches.

Opis:
Increase in the occurrence of multiple primary malignant tumours is associated with significant extention of survival rate among patients treated for malignant neoplasm. Treatment of multiple primary malignant tumours demands precise clinical evaluation, imaging, laboratory diagnostics and histopathological evaluation of the lesion. In the presented case immunohistochemical staining of lymphatic metastasis from nasopharyngeal carcinoma was mimicking distant metastasis from poorly differentiated ovarian cancer. It impeded histopathological diagnosis and required additional imaging enriched by PET-CT, which allowed the visualization of the second tumor.

Opis:
Introduction and objective. Peroxiredoxin-1 (PRDX-1) belongs to a family of antioxidant enzymes and has proved to be a versatile molecule regulating cell growth, differentiation and apoptosis. PRDX1-regulated signaling pathways play an important role in the progression and metastasis of human tumours, especially in breast, esophageal and lung cancers. The aim of the study was to evaluate the expression of PRDX-1 in ovarian cancer tissues, and to test the clinical value of PRDX-1 as a prognostic factor in this malignancy. Materials and method. PRDX-1 expression was assessed by automated immunohistochemistry in tumours taken from 55 patients with ovarian cancer during primary surgery. Specimen were formalin-fixed and preserved in paraffin-embedded blocks. The results were correlated with clinicopathological data. Results. A high expression of PRDX-1 was observed in 20% of cases, and was associated with worse compliance to chemotherapy protocol (P<0.002), worse response to chemotherapy (P<0.04), and higher levels of CA 125 after the 1st line treatment (P<0.004). PRDX-1 positive subjects had a significantly lower 5-year disease-free survival (9.1% vs. 42.6%, P<0.01) and a lower 5-year overall survival (9.1% vs. 56.7%; P<0.002). Multivariate analysis showed that a high expression of PRDX-1 is an independent prognostic factor of poor, overall survival (P<0.002) and a disease-free survival (P<0.01). Conclusion. Results of the study show that PRDX-1 expression in tumour tissues can be another biomarker of prognosis in patients with ovarian cancer.
