This study investigates the feasibility of using 3D-Printing to manufacture masks used to immobilize patients undergoing radiotherapy treatment for tumors affecting the head and neck.

Evaluation of individual peripheral blood circulating tumor cells combined with tumor marker detection of efficacy of chemotherapy in patients with advanced colorectal cancer: A observational clinical trial

The registry aims to compare the two first-line available treatment approaches in non-high-risk APL patients aged ≤ 70 years - ATRA plus chemotherapy and ATRA plus ATO - in terms of practitioner's choice between the two options, clinical effectiveness and cost-effectiveness, long-term outcome, and short- and long-term toxic effects.

Ovarian cancer is the third most common gynecological malignancy worldwide. Because of late, aspecific symptoms, the disease is usually diagnosed at an advanced stage. Most patients experience recurrence and die as a result of the disease within 5 years. Treatment is a combination of surgical debulking and systemic administered chemotherapy. Intra-peritoneal (IP) chemotherapy with is currently considered the most effective treatment. In patients with at least an optimal surgical debulking, this leads to an improvement in life expectancy from 50 to 66 months. IP administration of chemotherapeutic agents is still not common practice. Furthermore recent studies revealed that cancer cells express a variety of tumor antigens, which can be targeted by the immune system. Also ovarian cancer shows evidence of a role for the immune system in clinical outcome. Novel insights into the mechanism of action of chemotherapy indicate that the efficacy of chemotherapeutic interventions are dependent on the modulation of the immune system. The impression exists that since IP chemotherapy is used, relatively more recurrences outside the abdominal cavity are observed. As of yet, no studies have described pharmacokinetics and pharmacodynamics of IP administered cisplatin and paclitaxel in the blood circulation. The investigators propose to study the use of this aspiration fluid from the IP cavity as a biomarker for the efficacy of chemotherapy intervention, monitor the effect of chemotherapy on IP tumor cells in the peritoneal cavity and monitor the effect of chemotherapy on immune cells present in the IP cavity. As well the investigators propose to correlate the presence and amount of tumor cells in peritoneal fluid with the debulking efficacy and CA 125 levels. Secondary to this the investigators intend to determine the pharmacokinetics of cisplatin and paclitaxel when administered in the IP cavity in the central circulation (plasma) as well as in the peritoneal fluid. In this observational explorative study women, aged younger than 70 years, who will receive standard IP chemotherapy for advanced epithelial ovarian cancer, who are in an adequate physical and biochemical state to receive chemotherapy are included. Immunological cell counts, tumor marker, immunological cell pathway activation and plasma concentrations of cisplatinum and paclitaxel in venous blood and in fluid aspirated from the abdominal cavity will be measured.

The investigators hypothesize that an early molecular profiling, that includes both tissue and blood-bases analysis, for all NSCLC patients, including stage I-III, will increase diagnostic efficiency. When molecular profiles are available at an earlier stage of disease, more patients will benefit from personalized therapy once needed. This will result in both a better quality of life and outcome.

The long-term efficacy of chemotherapy in patients with acute myeloid leukemia (AML) has been significantly improved in recent years. The combination of anthracycline plus cytarabine (Ara-C) has been a standard induction regimen for patients with AML. However, the optimal consolidation therapy after induction chemotherapy has not reached a consensus. The FLAG regimen consisting of fludarabine and high-dose cytarabine combined with G-CSF which is one of the first-line consolidation treatment options for relapsed and refractory AML. This study conducted a retrospective analysis of the intensive treatment of AML with the FLAG regimen from January 2007 to May 2018 in our hospital to evaluate the efficacy of the FLAG regimen. To provide the basis for the choice and timing of treatment for patients with AML treated with the FLAG regimen.

The purpose of this study is to create a software product on the basis of the support technologies for making decisions for the collaboration of the different specialists, the family and the patient himself in the process of physical therapy of children treated for cancer. The basic model of the technology is a qualification model of the state of health and physical limitations, based on data from a survey of 1,000 children treated for cancer. The software product is supposed to be created on the basis of the Splunk system, the key link is a personal office with a two-way login system: for specialists and for patients. The patient introduces the results of self-examination, monitoring and additional surveys in real time, specialists - additional recommendations. To assess the effectiveness of the collaboration based on the software product, a long-term follow-up (at least 3 years) is planned for the participants of the study with repeated examinations at the Medical-Rehabilitation Scientific Center "Russe pole" at least twice a year.

Tomotherapy is a new radiation planning and delivery technology which may allow for delivery of higher radiation doses with less damage to normal tissues. The investigators aim to compare the treatment efficacy and quality of life between tomotherapy and intensity-modulated radiotherapy for patients with nasopharyngeal carcinoma

This study will investigate the effects of gut microbiome diversity (richness in terms of many bacterial species in the gut) on responses and side effects of immunotherapy in advanced melanoma patients. Immunotherapy for melanoma is especially damaging for the gut with colitis which can lead to death and significant morbidity with repeated hospital admissions. The richness of the microbiome in the gut may be protective against colitis and other side effects but this needs to be confirmed. There is also some preliminary evidence that the gut microbiome diversity can enhance responses to immunotherapy in cancer but this has been shown in small numbers of melanoma patients.

Pancreatic cancer (PC) is one of the most lethal diseases among all cancer types. The diagnosis of PC is usually based on radiology or invasive endoscopic techniques. Various types of tumor markers are used for diagnosing PC. The tumor markers carbohydrate antigen19-9 (CA 19-9) and carcinoembryonic antigen (CEA) are the ones most closely tied to PC. These tests are more often used in people already diagnosed with pancreatic cancer to help tell if treatment is working or if the cancer is progressing . Cell migration inducing protein (CEMIP) has been reported to be associated with early detection, cancer cell migration, invasion, and poor prognosis. Aim of the work: To Estimate the level of CEMIP, CA19-9 and CEA in pancreatic cancer patients. To evaluate the clinical utility of serum CEMIP, CA19-9 and CEA in pancreatic cancer patients in comparison with healthy controls and their relation to cancer staging and histopathological types. To detect the correlation between CEMIP, CA-19-9 and CEA.
