Opis:
Ovarian cancer is worldwide the leading cause of mortality in women with genital tract malignancy. Over one-half of patients are diagnosed with their ovarian cancer in the 3rd and 4th clinical stage. Currently, the standard protocol of management consists in surgery aiming at obtaining histological diagnosis, determination of clinical stage and cytoreduction followed by chemotherapy. At present, generally accepted chemotherapy protocol includes paclitaxel and platinum derivates (6 courses 3 weeks apart). Unfortunately, the outcome of this therapy is far from satisfactory and only about 20% of women with late-stage ovarian cancer survive over 5 years. Studies are underway aiming at improvement of the patients’ survival rate. Promising results are associated with intraperitoneal chemotherapy, which may be implemented as first-line treatment, consolidation of remission or salvage treatment. This modality may be an attractive alternative, because it by-passes peritoneal barrier, overcomes resistance of cancer cells, results in less systemic toxicity, increases exposure of tumour to high concentration of cytostatics. The newest GOG172 trial confirmed a 21.6% mean reduction of death risk. This study enabled to define a group of patients who may benefit most of intraperitoneal chemotherapy. These are patients in the 3rd clinical stage, after optimal surgical cytoreduction, with minimal residual disease. At present, great hopes are associated with the protocol including intraperitoneal cisplatin (100 mg/m2) and taxanes administered intravenously only or intravenously and intraperitoneally.
Rak jajnika jest na świecie główną przyczyną śmierci kobiet z powodu nowotworów narządu rodnego. U ponad połowy chorych nowotwór jajników jest rozpoznany w III° i IV° zaawansowania. Obecnie standardowe postępowanie obejmuje zabieg operacyjny, mający na celu uzyskanie diagnozy histopatologicznej, ocenę stopnia klinicznego zaawansowania, cytoredukcję, a następnie chemioterapię. Aktualnie powszechnie akceptowanym schematem chemioterapii jest paklitaksel i pochodne platyny (6 kursów co trzy tygodnie). Niestety rezultaty tej terapii są dalekie od oczekiwanych i tylko około 20% kobiet z zaawansowanym rakiem jajnika przeżywa 5 lat. Prowadzone są badania, których celem jest poprawa przeżywalności chorych. Obiecująca wydaje się być chemioterapia dootrzewnowa, która może być zastosowana jako terapia pierwszej linii, konsolidacyjna lub ratunkowa. Terapia ta może być atrakcyjnym sposobem leczenia, ponieważ pomija barierę otrzewnową, przełamuje oporność komórki nowotworowej, daje mniejszą toksyczność układową oraz większą ekspozycję guza na wysokie stężenie cytostatyków. Najnowsze badanie GOG172 potwierdziło średnie zmniejszenie ryzyka zgonu o 21,6%. Badanie to wyodrębniło grupę chorych, które mogą osiągnąć największą korzyść z chemioterapii dootrzewnowej. Są to pacjentki z nowotworem w III° zaawansowania, po optymalnym zabiegu cytoredukcyjnym, z minimalną chorobą resztkową. Obecnie za budzący nadzieję uważa się schemat zawierający IP cisplatynę 100 mg/m2 i taksany podawane tylko IV lub IV i IP.

Opis:
Numerous studies of mitochondrial DNA (mtDNA) in cancer have shown differences between mtDNA sequences in tumor and normal tissue and at various stages of cancer treatment in the same patient. However, there is little data on acute lymphoblastic leukemia (ALL), the most common type of leukemia in children. In this study we compared mitochondrial sequence variation in the D-loop region and in 5 genes of mtDNA in bone marrow samples of 6 pediatric patients with ALL at various stages of therapy. We found several common polymorphisms and one variant at position 3688 whose level varied during leukemia treatment. Our results suggest that mitochondrial DNA mutations, whose levels change during patient treatment, could be potential biomarkers for monitoring treatment efficacy and disease progression.

Opis:
Taxanes, whose mechanism of action is based on blocking the cells’ division of cells, have been commonly used in the chemotherapy process for over two decades. The indications for the use of taxanes include ovarian cancer, breast cancer, lung cancer, prostate cancer, some of gastrointestinal malignant tumors or Kaposi sarcoma. Currently, chemotherapy based on taxanes, as well as every cytostatic medicine, allows to improve survival outcomes in many patients with diagnosed malignancies, although it also involves the occurrence of adverse effects. These adverse events may be life-threatening or at least they can decline the patient’s quality of life. The main aim of this paper is to feature possible ocular side effects during taxane based chemotherapy. Physicians taking care of patients during chemotherapy based on taxanes, as well as on every other cytostatic medicine, should be aware of these probable ocular complications. An early diagnosis of ophthalmic complications caused by chemotherapy makes it possible to avoid long-lasting adverse effects.

Opis:
Anaemia is one of the most frequently diagnosed complications in cancer patients and also occurs during the course of cancer treatment. The condition can be observed in as many as 60–70% of patients who receive chemotherapy or radiotherapy. As a cancer symptom, it is found in 30% of cases and is particularly severe when accompanied by kidney failure. In patients undergoing cancer therapy, anaemia is treated with PRBC transfusions and/or recombinant human erythropoietin. The article discusses 3 case studies of patients with late-stage cancer (pleural mesothelioma, urothelial kidney carcinoma, and lung carcinoma), who suffered from moderate to severe anaemia during aggressive treatment with chemo- and radiotherapy. All 3 patients were treated with erythropoietin, which made it possible for them to stay on chemotherapy and/or undergo radiotherapy. Thanks to erythropoietin, they did not require PRBC transfusions and their general condition and quality of life improved. They tolerated the treatment well and no complications were observed.

Opis:
In the field of pharmacological therapy, due to the high costs and other obstacles encountered in developing novel drugs, a variety of studies have recently focused on repositioning existing pharmaceutical agents. Regarding the pharmacotherapy of cancer, many possible drugs may exhibit anticancer effects owing to the vast number of biological mechanisms involved in the proliferation and survival of malignant cells. Telmisartan, a well-known inhibitor of the angiotensin II receptor used clinically as an antihypertensive, has been shown to target various signaling pathways in cancer cells, therefore exhibiting anti-proliferative, anti-apoptotic and anti-metastatic effects. Moreover, inhibitors of the angiotensin II receptor have been shown to increase the fluidity of the tumor microenvironment, thus increasing the efficacy of chemotherapy as drug delivery to the tumor is enhanced. The present review provides an insight into the different anticancer mechanisms of telmisartan, as well as recent and past studies which have tested the drug in vitro and in vivo on different types of cancers. This may provide a perspective for future clinical trials on repositioning telmisartan as an anti-cancer agent.

Opis:
Chemotherapy Induced Nausea and Vomiting (CINV) remains one of the most frequent adverse effects of cancer chemotherapy, often leading to patient non-adherence to the prescribed chemotherapeutic regime, as well as several associated complications. Current antiemetic therapy has been reported to provide relief of CINV in 75%-80% of patients, still leaving margin for improvement. This makes the development and study of novel antiemetics, especially those providing relief of both early and late phases of CINV, a matter of prime importance. The purpose of this review is to illustrate the mechanism of action of cannabinoid substances and provide a general view into their current use as antiemetic drugs in clinical practice. Several research articles pertaining the subject were compiled and studied. This review presents the information thereby obtained. It is concluded that cannabinoids possess value as antiemetic drugs, along with certain properties that set them apart from other classes of antiemetic substances.

Introduction. Cancer treatments are now intense and are associated with nutritional deficiencies. The nutritional status of a patient may influence the tolerability of chemotherapy. Aim. We investigated the effects of chemotherapy on serum levels of trace elements (copper, iron, manganese, selenium, and zinc) and vitamins (A, C, and E) in patients with mature lymphoid malignancies (MLMs) at diagnosis and after 3 months. Material and methods. A case-control study of adults diagnosed with and treated for various MLMs. Thirty-nine cases and 39 age and sex-matched controls were recruited into this study. Venous blood samples were collected from the controls, cases at baseline and after 3 months of chemotherapy. Trace elements were determined by AAS while vitamins were determined by HPLC. Results. The levels of trace elements and antioxidant vitamins A and E were significantly higher (p<0.001) in cases than in controls while vitamin C was lower in cases compared to controls (p=0.005). After 3 months of treatment, 28 patients were available for analysis. There was a significant decline (p<0.001) in all the levels of trace elements and vitamins after chemotherapy. Conclusion. Chemotherapy is associated with a significant reduction in antioxidants levels in patients with MLMs.

Introduction: The most common form of cardiotoxicity in cancer treatment is anthracycline-related cardiomyopathy. Objective: To study the factors affecting response to heart failure (HF) therapy in patients with anthracycline- related cardiomyopathy (ARC). Methods: Patients with ARC were included in the study. ARC was defined as left ventricular ejection fraction (LVEF) < 50% in patients who had received anthracycline based chemotherapy. 2Decho was done at baseline and every 3 months after starting anti-heart failure treatment. The primary endpoint of the study was response to anti-heart failure treatment. The patients were considered as responders when LVEF increased at least 10 absolute points. The secondary endpoint was overall survival. Results: 177 patients with ARC were included in the study. The median cumulative dose of doxorubicin was 275 mg/m2. Median clinical follow up duration was 19 months (range 3–73 months). 55% were responders. 25 cumulative doxorubicin dose of more than 200 mg/m2 increased the likelihood of non-response (p = 0.008), by a factor of 3.07 (95% CI: 1.34–7.05). 25 patients expired. There was a significant difference in overall survival among responders as compared to non-responders (p value: 0.002, log rank test). Conclusions: In patients with ARC cumulative doxorubicin dose of more than 200 mg/m2 increased the likelihood of non-response to anti-heart failure treatment. Responders have a better overall survival compared to non-responders in patients with ARC.

The achieve pathologic complete response is proven to be the most important parameter of prognosis. Thereports evaluating the impact of obesity on the obtained pathologic response to chemotherapy are unequal. The aim of the study was to evaluate in locally advanced breast cancer patients, treated with AT(doxorubicin plus docetaxel) neoadjuvant chemotherapy: 1. The relationship of obesity with obtaining pathological response. 2. The relationship of obesity and free of disease recurrence survival (DFS) and overall survival (OS) associated with the tumour. Material and methods. A retrospective study was carried out in a group of 105 patients with locally advanced breast cancer, treated with AT neoadjuvant chemotherapy and then treated with radical surgery. Two variants of pathological response have been adopted: a pCR (T0N0) and pCR1 (TisN0, TxN1, T1N0, T1N1, T0N1). The relationship of obesity with pathological response and survival was investigated. Results. In univariate analysis the pCR1 was obtained with its arising from the borderline of statistical significance with lower incidence of obesity. In pCR1 multivariate analysis, negative pCR1 relationship with obesity was on the borderline of the statistical significance. The multivariate analysis showed a significant negative association OS with obesity (p=0.047) and positive with the occurrence of menopause (p = 0.029). Conclusions. In patients with locally advanced breast cancer treated with AT neoadjuvant chemotherapy. 1. Obesity seems to be an independent and unfavourable predictor of the lack of obtaining pCR1 pathological response 2. In the multivariate analysis, the obesity was a significant independent factor related to shorter OS.

The routine and the most effective method of viruses elimination from potato plants is in vitro culture of apical shoots combined with thermo- and/or chemotherapy. At times electrotherapy or cryotherapy is also applied. Elimination of potato viruses by thermotherapy required treatment of infected plants with high tem-perature (35°C - 45°C) for about two weeks. Thermotherapy is useful for elimination of PLRV and PVY from potato plants. In chemotherapy antimetabolite, like ribavirin is used. Chemotherapy is dedicated for elimina-tion of PVM, PVS and PVX. Very often the successful virus elimination require a few cycles of thermo- and/or chemotherapy.

Opis:
The paper is a detailed review of recent advances in the treatment of ovarian cancer patients using intraperitoneal chemotherapy. Theoretical basis of intraperitoneal treatment is discussed, this being understood as passage of substances through semipermeable membrane, where rate of passage depends on peritoneal clearance, size and electric charge of particles and concentration gradient. History of intraperitoneal treatment is reviewed, starting with early works by Green and Kottmeier dating back to the ‘50s, and ending with recent studies, including a meta-analysis of 8 randomized trials of first-line treatment published within the past 12 years, which included a total of 1819 patients. The authors discuss reasons for issuing pertinent recommendations by the US National Cancer Institute, emphasizing the leading role of intraperitoneal chemotherapy in the treatment of ovarian cancer patients. Effectiveness of platinum derivates-based chemotherapy in consolidation treatment is discussed, supported by a review of pivotal papers concerning this subject. The paper presents and discusses key reports on implementation of intraperitoneal chemotherapy in consecutive lines of treatment of ovarian cancer, as well as the role of cisplatin and carboplatin in intraperitoneal therapy, highlighting differences in outcome after application of both agents. Emphasized are also limitations of the method. Next, the authors review surgical complications arising during procedures associated with implementation of intraperitoneal chemotherapy, as well as several aspects of complications resulting in premature interruption of intraperitoneal chemotherapy (on the average: 50% of cases; up to 60% in the GOG 172 trial). Critique of the method, mainly on the part of European centers, is referred to.
W prezentowanej pracy szczegółowo omówiono najnowsze aspekty dotyczące leczenia chorych na raka jajnika przy użyciu chemioterapii dootrzewnowej. Przedstawiono podstawy teoretyczne leczenia dootrzewnowego jako przepływu substancji przez błonę półprzepuszczalną, gdzie prędkość przepuszczania substancji zależy od ich klirensu otrzewnowego, wielkości cząsteczki i jej ładunku oraz stosunku stężeń. Omówiono historię leczenia dootrzewnowego – od pierwszych prac Geena i Kottmeier z lat 50. do chwili obecnej – a także wyniki ośmiu randomizowanych badań poświęconych leczeniu pierwszej linii, przeprowadzonych w ciągu ostatnich 12 lat, w których przebadano 1819 pacjentów. Autorzy odnoszą się do powodów wydania zalecenia National Cancer Institute dotyczącego nadrzędnej roli chemioterapii dootrzewnowej w leczeniu chorych na raka jajnika. Przedstawiają znaczenie chemioterapii dootrzewnowej opartej na pochodnych platyny w leczeniu konsolidującym, analizując ważniejsze prace dotyczące tego tematu. W artykule zaprezentowano i przeanalizowano główne doniesienia na temat leczenia za pomocą chemioterapii dootrzewnowej w kolejnych liniach leczenia raka jajnika, jak również rezultaty badań nad wykorzystaniem cisplatyny i karboplatyny w terapii dootrzewnowej, co pozwoliło wykazać różnice w wynikach po zastosowaniu tych pochodnych platyny. Zwrócono także uwagę na ograniczenia metody. Oprócz tego autorzy opisali powikłania chirurgiczne występujące podczas operacji mających związek ze stosowaniem chemioterapii dootrzewnowej, omówili aspekty związane z powikłaniami będącymi przyczyną przedwczesnych ukończeń chemioterapii dootrzewnowej (50%, a w badaniu GOG 172 nawet 60% przypadków) oraz odnieśli się do krytyki tej metody płynącej głównie z ośrodków europejskich.

Vindoline and its analogues are important constituents of the Madagascan periwinkle Catharanthus roseus, and some of them are valuable chemotherapy drugs used in treatment for some types of cancer, including leukaemia, lymphoma, breast and lung cancer. The search for semi-synthetic congeners of natural substances is still an important task for organic chemistry. In this communication we report the synthesis of five new vindoline derivatives, 15-(2-methoxyphenyl)vindoline 11, 15-(3-methoxyphenyl)vindoline 12, 15-(2-nitrophenyl)vindoline 13, 15-(3-cyanophenyl)vindoline 15, and 15-(4-cyanophenyl)vindoline 16 using the Suzuki-Miyaura reaction as the key step. X-Ray analysis of compound 16 is also reported.

Opis:
Pancreatic cancer is one of the malignant neoplasms with the worst prognosis. It is most often diagnosed at an advanced stage, which relates to unsatisfactory results of the therapy. Only about 15–20% of patients with pancreatic cancer qualify for surgery. The remaining patients are diagnosed with locally advanced disease or much more frequently in the generalized stage. Systemic treatment (chemotherapy) remains the mainstay of therapy in these patients, but both the response rate and progression-free time are unsatisfactory [1, 2]. This paper presents a case of a patient with metastatic pancreatic cancer, in whom three lines of systemic treatment were applied sequentially, which allowed to extend the survival time and improve the quality of life.
