There is emerging interest in the relationship between several serum micronutrients and the prognosis of patients with breast cancer. The relationship between serum zinc and copper levels and breast cancer prognosis is unclear. In our study, we included 583 patients with breast cancer diagnosed between 2008 and 2015 in the region of Szczecin, Poland.

Organ-sparing combined-modality treatment for muscle-invasive bladder cancer remains underutilized despite high-quality evidence regarding its efficacy, safety, and preservation of quality of life. It may be offered to patients unwilling to undergo radical cystectomy, as well as those unfit for neoadjuvant chemotherapy and surgery. The treatment plan should be tailored to each patient's characteristics, with more intensive protocols offered to patients who are fit for surgery but opt for organ-sparing.

Adjuvant whole breast irradiation (AWBI) improves local control and survival in breast cancer patients after breast-conserving surgery. Between 2010 and 2017, 823 patients ≥ 60 years with ER-positive, Her-2 negative, clinically N0 breast cancer underwent breast-conserving surgery (BCS) at the West Pomeranian Oncology Center. Intraoperative radiotherapy (IORT) with kV photons was applied to 199 (24.

Background: To estimate the impact of oophorectomy and other treatments on the survival of breast cancer patients with a CHEK2 mutation.

Methods: Women with Stage I-III breast cancer who were treated at 17 hospitals in Poland were tested for four founder mutations in the CHEK2 gene. 974 women (10%) were positive for a CHEK2 mutation.

Article Synopsis
  • The study estimated the risk of developing thyroid cancer in patients who had previously been diagnosed with breast cancer, tracking 10,832 women for an average of 14 years.
  • Out of the participants, only 53 (0.49%) developed thyroid cancer, significantly higher than the expected rate based on Polish population statistics.
  • Women with specific mutations in the CHEK2 gene showed a higher ten-year risk of thyroid cancer (1.5%) compared to those without mutations (0.9%), with particular mutations linked to higher hazard ratios for developing the disease.

Background: The present paper reports on analysis of 184 patients who were diagnosed with endometrial cancer. The main objective of this study was to address parameter V which determines a volume of the rectum irradiated with a dose of 30 Gy during radiotherapy.

Materials And Methods: All patients were irradiated with an IMRT technique on linear accelerators.

Background: Breast cancer patients with positive sentinel lymph node biopsy (SLNB) may be spared axillary lymph node dissection (ALND) in favour of irradiation. The aim of the study was to estimate local control probability in the axilla (axLCP).

Materials And Methods: We identified 1832 invasive breast cancer patients who had undergone SLNB at our centre.

An important group of breast cancers is those associated with inherited susceptibility. In women, several predisposing mutations in genes involved in DNA repair have been discovered. Women with a germline pathogenic variant in have a lifetime cancer risk of 70%.

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.

Background: Patients with left breast cancer who undergo radiotherapy have a non-negligible risk of developing radiation-induced cardiovascular disease (CVD). Cardioprotection can be achieved through better treatment planning protocols and through respiratory gating techniques, including deep inspiration breath hold (DIBH). Several dosimetric studies have shown that DIBH reduces the cardiac dose, but clinical data confirming this effect is limited.

Purpose: Sentinel lymph node biopsy is routinely used in breast cancer patients with clinically negative axillary lymph nodes. Locoregional relapses after negative sentinel lymph node biopsy are infrequent, occurring in up to 3% of patients.

Methods: Six thousand and eight patients underwent breast cancer surgery in our center between 2006 and 2015.

Introduction: Intraoperative radiotherapy (IORT) based on low-kV photons may be an option for early breast cancer patients. Following Targit trial results some of those patients should undergo whole breast irradiation (WBRT) additionally.

Material And Methods: Since April 2010, IORT has been applied to early breast cancer patients.

Arsenic is recognized as a potent carcinogen at high concentrations, but the relationship between environmental arsenic and breast cancer risk has not well been studied. Most research has focused on the effect of arsenic in populations with high endemic exposure, and not in populations with arsenic levels within normal limits. We sought to determine if blood arsenic levels predict the risk of breast and other cancers risk among women in northern Poland.

Introduction: Omission of axillary lymph node dissection (ALND) after positive sentinel lymph biopsy (SLNB) has become a standard procedure for breast cancer patients with one or two metastatic lymph nodes. Here the aim was model development for selection for ALND.

Material And Methods: We analyzed 323 positive SLNB breast cancer patients, who afterwards underwent ALND.

Background: Observational studies have reported an inverse relationship between selenium status (blood or toenail) and the risk of laryngeal cancer; however, the impact of low serum selenium level on survival has not been evaluated.

Methods: We conducted a prospective study of 296 patients diagnosed with laryngeal cancer in Szczecin, Poland. Serum selenium was measured at diagnosis and prior to treatment.

Background: Accelerated partial breast irradiation (APBI) is a promising method of adjuvant radiotherapy for select patients. Intraoperative radiotherapy (IORT) is a form of APBI, and appropriate patient selection is important.

Aim: The aim of our study was to analyse the influence of our protocol on the frequency of WBRT after IORT and our protocol's correlation with the reported use of WBRT according to TARGIT guidelines.

Aims: Breast cancer is the most common cancer among women, and anthracyclines are the most commonly administered drugs for these patients. Cardiotoxicity is one of the complications, which limits the success of this therapy. Very few studies have evaluated anthracycline toxicities within the first few hours after the first infusion, and the majority of published studies were performed in animal models.

This work describes the use of 3D printing technology to create individualized boluses for patients treated with electron beam therapy for skin lesions of the eye canthi. It aimed to demonstrate the effectiveness of 3D-printed over manually fabricated paraffin boluses. The study involved 11 patients for whom the construction of individual boluses were required.

Background: Novel techniques in oncology provide new treatment opportunities but also introduce different patterns of side effects. Intraoperative radiotherapy (IORT) allows a shortened overall treatment time for early breast cancer either combined with whole breast radiotherapy (WBRT), or alone. Although the early side effects of IORT are well known, data on clinically important late side effects, which require medical intervention, are scarce.

Introduction: Cardiotoxicity of drugs in oncology is a growing problem which cardiologists and oncologists have to struggle with. So far, researchers have been looking for biochemical markers which could help to extract a group more prone to developing complications after chemotherapy. Authors’ reports are inconsistent in this topic.
