Article Synopsis
  • The rising incidence of colorectal cancer has emphasized the need for enhanced surgical training, particularly in Poland, where changes to the training program have increased the number of required intestinal procedures for residents.
  • A multicenter study (LILEO study) involving 199 patients aimed to evaluate ileostomy reversal safety, comparing outcomes between surgeries performed by specialist surgeons and those done by surgical residents.
  • Results showed that while the resident group had a shorter hospital stay and a lower overall complication rate, these differences weren't statistically significant; however, minor complications were more prevalent in the specialist group, indicating that resident-performed ileostomy reversals are safe and effective.

Loop ileostomy is commonly performed by colorectal and general surgeons to protect newly created large bowel anastomoses. The optimal timing for ileostomy closure remains debatable. Defining the timing associated with the best postoperative outcomes can significantly improve the clinical results for patients undergoing ileostomy closure.

Despite advances in early detection and treatment strategies, breast cancer recurrence and mortality remain a significant health issue. Recent insights suggest the prognostic potential of microscopically healthy mammary gland, in the vicinity of the breast lesion. Nonetheless, a comprehensive understanding of the gene expression profiles in these tissues and their relationship to patient outcomes remain missing.

Male sex is a risk factor for colorectal cancer (CRC) with higher illness burden and earlier onset. Thus, we hypothesized that loss of chromosome Y (LOY) in the tumor micro-environment (TME) might be involved in oncogenesis. Previous studies show that LOY in circulating leukocytes of aging men was associated with shorter survival and non-hematological cancer, as well as higher LOY in CD4 + T-lymphocytes in men with prostate cancer vs.

The majority of current methods for measuring the angular deflection of a laser beam enable measurement only in one selected plane. However, there are tasks in which measurements of laser beam deflections in 3D are required. In this paper, we present a way of enabling two-axial measurements of the deflection of a beam based on a single-axis sensor.

Article Synopsis
  • The study analyzed data from 248 melanoma patients in advanced stages (III and IV) who received adjuvant therapies at eight medical centers between February 2019 and January 2021.
  • Patients were treated with either anti-PD1 therapies (nivolumab or pembrolizumab) or a combination of dabrafenib and trametinib, showing two-year survival rates of 86.7% for overall survival, 61.4% for relapse-free survival, and 70.2% for distant-metastases-free survival.
  • The findings suggest that adjuvant therapies are effective outside of clinical trials and support the idea of reducing the extent of surgery in melanoma treatment.

Colorectal cancer (CRC) is the third most common malignancy and the second most common cancer-related cause of death worldwide. CRC incidence depends, in part, on the health behaviors that make up an individual's lifestyle. We aimed to assess the influence of health behaviors and quality of life (QoL) among patients with CRC receiving surgical treatment.

Introduction: Correct surgical technique and perioperative care are two factors that can reduce the number of complications, improve treatment outcomes and shorten the length of hospital stay. The introduction of enhanced recovery protocols has changed the approach to patient care in some centers. However, there are significant differences among centers, and in some the standard of care has remained unchanged.

The mammary gland undergoes hormonally stimulated cycles of proliferation, lactation, and involution. We hypothesized that these factors increase the mutational burden in glandular tissue and may explain high cancer incidence rate in the general population, and recurrent disease. Hence, we investigated the DNA sequence variants in the normal mammary gland, tumor, and peripheral blood from 52 reportedly sporadic breast cancer patients.

The progress in translational cancer research relies on access to well-characterized samples from a representative number of patients and controls. The rationale behind our biobanking are explorations of post-zygotic pathogenic gene variants, especially in non-tumoral tissue, which might predispose to cancers. The targeted diagnoses are carcinomas of the breast (via mastectomy or breast conserving surgery), colon and rectum, prostate, and urinary bladder (via cystectomy or transurethral resection), exocrine pancreatic carcinoma as well as metastases of colorectal cancer to the liver.

Article Synopsis
  • Recent advancements in melanoma research have significantly changed the clinical management of stage III melanoma, focusing on practical applications.
  • Studies like MSLT-II and DeCOG-SLT have challenged the traditional belief that all patients with sentinel node metastasis require a completion lymphadenectomy, showing that omitting this procedure does not adversely affect survival rates.
  • Modern immunotherapy and targeted therapy have been proven to enhance recurrence-free survival by 10-20% in stage III melanoma patients, leading to improved treatment approaches with fewer surgical complications and better overall outcomes.
