Factors determining the quality of life in patients undergoing radical surgery due to malignant tumors of the rectum.

Introduction: Rectal cancer is one of the most common malignancies in developed countries. However, despite the increasingly better preoperative diagnostics, adaptation of surgical techniques to the location and advancement of the tumor, the combination of surgical treatment with neoadjuvant therapy and adjuvant treatment, standardized control tests, Poland still has not obtained satisfactory results regarding long-term survival. In addition, the effects of the therapy often differ significantly from those expected by patients and the doctors treating them.

Colorectal cancer and Blastocystis sp. infection.

Background: Blastocystis sp. is a common intestinal protozoan found worldwide. Based on gene analysis, 17 subtypes (STs, ST1-ST17) have been identified, 9 of which have been isolated from humans.

Serum Selenium Level Predicts 10-Year Survival after Breast Cancer.

In a recent prospective study, we reported an association between a low serum selenium level and five-year survival among breast cancer patients. We now have updated the cohort to include 10-year survival rates. A blood sample was obtained from 538 women diagnosed with first primary invasive breast cancer between 2008 and 2015 in the region of Szczecin, Poland.

Long-course preoperative chemoradiation versus 5 × 5 Gy and consolidation chemotherapy for clinical T4 and fixed clinical T3 rectal cancer: long-term results of the randomized Polish II study.

Background: This trial evaluated whether preoperative short-course radiotherapy and consolidation chemotherapy (CCT) were superior to chemoradiation in rectal cancers with clinical (c)T4 or fixed cT3. Previously, we reported early results showing no differences in the radical surgery rate (primary end point). In the short-course/CCT group, we observed lower acute toxicity of preoperative treatment and better overall survival (OS).

Colorectal cancer and Cryptosporidium spp. infection.

Unlabelled: Transient or constant impaired immunity is often associated with neoplastic disease or oncological treatment. Among the most common pathogens found in patients with HIV or patients undergoing chemotherapy are protozoans of the Cryptosporidium genus, which cause diarrhea in humans and animals. The present study determined the frequency of Cryptosporidium spp.

Serum selenium levels predict survival after breast cancer.

Background: Studies have reported an inverse relationship between serum selenium levels and cancer incidence, but the impact of low serum selenium status on survival after a diagnosis of breast cancer has not been established.

Methods: We obtained a blood sample from 546 women diagnosed with a first primary invasive breast cancer between 2008 and 2015 in the region of Szczecin, Poland. Blood was collected after diagnosis, but prior to treatment.

The usefulness of D-dimer in diagnosis and prediction of venous thromboembolism in patients with abdominal malignancy.

The Aim: of the study was to evaluate the usefulness of D-dimer evaluation in the diagnosis and prediction of venous thromboembolism (VTE) of lower extremities in patients operated on for abdominal tumors depending on the chosen cut-off point for this parameter.

Material And Methods: We included 150 patients operated on for abdominal cancer in our department between October 2014 and June 2016. In these patients, concentration of D-dimer was determined, medical histories were taken, and physical examinations were performed.

Do founder mutations characteristic of some cancer sites also predispose to pancreatic cancer?

Understanding of the etiology and risk of pancreatic cancer (PaCa) is still poorly understood. This study evaluated the prevalence of 10 Polish founder mutations in four genes among PaCa patients and assessed their possible association with the risk of disease in Poland. In the study 383 PaCa patients and 4,000 control subjects were genotyped for founder mutations in: BRCA1 (5382insC, 4153delA, C61G), CHEK2 (1100delC, IVS2 + 1G > A, del5395, I157T), NBS1 (657del5) and PALB2 (509_510delGA, 172_175delTTGT).

Serum Concentrations of Selenium and Copper in Patients Diagnosed with Pancreatic Cancer.

Purpose: Understanding of the etiology and pathogenesis of pancreatic cancer (PaCa) is still insufficient. This study evaluated the associations between concentrations of selenium (Se) and copper (Cu) in the serum of PaCa patients.

Materials And Methods: The study included 100 PaCa patients and 100 control subjects from the same geographical region in Poland.

The Influence Of Obesity On Results Of AT (Doxorubicin Plus Docetaxel) Neoadjuvant Chemotherapy In Locally Advanced Breast Cancer Patients.

Unlabelled: 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.

Selenium as a marker of cancer risk and of selection for control examinations in surveillance.

Publication is summarization of existing data being results of literature review and our experience on usefulness of selenium as a diagnostic marker selection for control examinations in surveillance and as a marker of patients with high risk of cancers.

Polymorphisms in nucleotide excision repair genes and susceptibility to colorectal cancer in the Polish population.

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease that is associated with a severe deficiency in nucleotide excision repair. Genetic polymorphisms in XP genes may be associated with a change in DNA repair capacity, which could be associated with colorectal cancer development. We assessed the association between 94 single nucleotide polymorphisms (SNPs) within seven XP genes (XPA-XPG) and the colorectal cancer risk in the Polish population.

Role of sonography in assessing complications after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy, which was introduced to the arsenal of surgical procedures in the middle of the 1980s, is a common alternative for conventional cholecystectomy. Its primary advantage is less invasive character which entails shorter hospitalization and faster recovery. Nevertheless, the complications of both procedures are comparable and encompass multiple organs and tissues.

Prevalence of the E318K and V320I MITF germline mutations in Polish cancer patients and multiorgan cancer risk-a population-based study.

The E318K mutation in the MITF gene has been associated with a high risk of melanoma, renal cell carcinoma, and pancreatic cancer; the risk of other cancers has not been evaluated so far. Herein, we examined the possible association of E318K and a novel variant of the MITF gene, V320I, with the risk of cancers of different sites of origin in a Polish population. We assayed for the presence of the E318K and V320I missense mutations in 4,226 patients with one of six various cancers (melanoma or cancer of the kidney, lung, prostate, colon, or breast) and 2,114 controls from Poland.

Tissue reactions of abdominal integuments to surgical sutures in sonography.

Unlabelled: Classical abdominal surgeries usually require long incisions of the abdominal integuments followed by tight closure with adequate suturing material. Nonabsorbable sutures may cause various reactions, including granuloma reactions, both sterile and inflammatory.

The Aim Of The Study: The aim of the study was to analyze prospective ultrasound examinations of the abdominal integuments in order to detect tissue reactions to surgical sutures.

Can selenium levels act as a marker of colorectal cancer risk?

Background: Selenium has attracted attention because of its antioxidant properties. Antioxidants protects cells from damage. Certain breakdown products of selenium are believed to prevent tumor growth by enhancing the immune cell activity and suppressing the development of tumor blood vessels.

Prevalence of Cryptosporidium sp. in patients with colorectal cancer.

Unlabelled: Parasitic protozoans of the Cryptosporidium genus are intracellular intestinal parasites of mammals, causing cryptosporidiosis. Clinically, cryptosporidiosis manifests as chronic diarrhoea. Individuals with immune disorders, including those with neoplasms, are at risk of symptomatic invasion.
