Opis:
Overtreatment means treatment that goes beyond current standards, and patients with any disease can be overtreated. Overtreatment is also given to patients with cancer, including those who need surgery. Overtreatment is closely related to the problem of overdiagnosis. In patients with cancer, unnecessary surgery may cause complications and generates unnecessary costs. The size of the problem of unnecessary surgery in patients with cancer can best be shown among patients with the most common cancers, which dedicated screening programs. Breast cancer patients, particularly those with pre-invasive types of the tumor, who typically have ductal carcinoma in situ (80%), are likely to undergo unnecessary surgery. We describe the most common clinical problems caused by overtreating patients with ductal carcinoma in situ.

Opis:
Introduction: Pancreatic cancer is characterized by its aggressiveness and poor prognosis. Furthermore, mortality is one of the highest among all types of cancers. It has been observed that the expression of Fascin-1 (the actin-bundling protein which enables the motility of cells) is higher in cancer cells and is correlated with invasiveness and metastasis. Purpose: To investigate the expression of Fascin-1 in histopathological specimens from patients treated for pancreatic cancer and its relationship with histopathological parameters. Materials and methods: The study was performed on a group of 52 patients diagnosed with pancreatic cancer in the Medical University of Bialystok Clinical Hospital. The expression of Fascin-1 was evaluated in tissue samples using the immunohistochemical method and was rated as “present” or “absent”. The analysis of histopathological parameters was performed in correlation with Fascin-1 expression. Results: Fascin-1 expression was observed in the cytoplasm of cancer cells in 42/52 cases (80.8%). Fascin-1 expression occurred more frequently among patients with lymph node metastases (92.6%) than without this type of metastases (68%) (p=0.024). Likewise, the expression of the investigated protein was observed more often with the presence of distant metastases (100%) than without those metastases (74.4%) (p=0.043). There were no statistically significant differences about age, sex, histological type of cancer, grade of histological differentiation, desmoplasia, inflammatory infiltration, foci of hemorrhage, necrosis, and MVD. Conclusion: The expression of Fasicn-1 is correlated with the presence of metastases and can be a useful marker of pancreatic cancer involvement.

Opis:
Diagnose of ductal carcinoma in situ (DCIS) requires, at least in a part of cases, assessment of auxiliary lymph nodes. The aim of the study was to analyze clinical value of Van Nuys Prognostic Index (VNPI) as the important criterion for qualification of DCIS patients to sentinel lymph node biopsy (SLNB). Material and methods. Analysis included patients diagnosed with DCIS and qualified to SLNB, operated in years 2004-2013. We performed a statistical analysis to assess correlation between VNPI value and positive pathological verification of excised sentinel lymph node (SLN). The influence of other clinical factors on presence of metastases in SLN was also determined. Results. 3,6% of DCIS patients were diagnosed with metastases in SLN. Metastases were diagnosed in 6.7% patients with VNPI > 10 points vs 3.4% in patients with VNPI < 10 points. In 75% of patients with metastatic SLN the value of VNPI was at least 10 points. In premenopausal patients metastases in SLN were diagnosed in 8.1% of cases vs 1.4% in postmenopausal patients. In patients diagnosed with cancer of the other breast metastases in SLN were found in 6.3% of cases vs 3.2% in one-sided cancer. Patients with multifocal cancer were over twice as often diagnosed with metastases in SLN (5% vs 2%). There was no correlation found between VNPI value and positive pathological verification of SLN. No differences between prevalence of SLN metastases depending on selected clinical features were found. Conclusions. Recommendation of VNPI as the criterion of qualification to SLNB starting with 10 points could be more favourable in patients with DCIS. Deciding on SLNB in DCIS patients, we should also take into consideration other clinical features.

Opis:
Introduction: Invasive lobular carcinoma (ILC) occurs in 5–15% of all cases of breast cancer. In most studies, it is found to be more common among older patients, form larger tumours and present with ill-defined margins, in comparison to invasive ductal carcinoma (IDC). Material and methods: Histological preparations were obtained from 651 patients suffering from breast cancer. Preparations stained with hematoxylin and eosin were used to identify tumour type and grading. Samples underwent a basic molecular profile evaluation encompassing ER (oestrogen receptor), PR (progesterone receptor) and human epidermal growth factor receptor 2 (HER2) expression. Results: 592 cases of IDC and 59 cases of ILC were detected. The median age was 60 in both groups. While there were no statistically significant differences between IDC and ILC in nodal status and tumour size for all age groups, IDC was more frequently diagnosed at higher grading (G3). G3 accounted for 32% of all IDC specimens compared to only 13% of ILC specimens. In both groups, the most prevalent combination of hormone receptors was ER+/PR+/HER2-. The differences in ER and PR expression were statistically significant; both were assessed as positive in most ILC cases and just over half of IDC. No HER2 amplification was noted in most cases in both cancer subtypes. Conclusions: In our study, IDC and ILC showed no difference with respect to patients’ median age at the diagnosis and local disease advancement defined by TNM. ILC cases were hormone-dependent and HER2-negative more frequently than IDC. Grade 3 tumours accounted for a higher proportion of IDC cases. This was in line with several other clinicopathological analyses of breast cancer. However, there are also several papers indicating ILC’s association with favourable prognostic features, not only in terms of hormone receptors and HER2 expression but also tumour size and nodal involvement. This underlines the fact that clear differences between IDC and ILC prognosis still cannot be established.

Opis:
Purpose: Pancreatic intraepithelial neoplasia (PanIN) is one of the most commonly occurring precancerous lesion in pancreas which leads to development of pancreatic ductal adenocarcinoma (PDAC). We assessed the presence and grade of pancreatic intraepithelial neoplasia in the course of various diseases of the pancreas and its correlations with chosen clinicopathological parameters. null Results: A total of 276 foci of PanIN were identified in 94 patients. The most common lesions were PanIN 1a and PanIN 1b which together constituted 68.2 % of all lesions, whereas the PanIN 2 was present in 21.7% and PanIN 3 in 10.1% of patients. No statistical differences were observed in gender tendency for the development of PanINs. There was correlation between age of patients and degree of PanIN (p=0.034). There is no statistical difference in PanIN frequency among patients with pancreatic ductal adenocarcinomas, neuroendocrine tumors, chronic pancreatitis and pancreatic cysts (p=0.592). Conclusions: Our study showed that important factor in development of pancreatic intraepithelial neoplasia is age and the presence of PanIN in nonneoplastic diseases in older people should be included to the group with increased risk of cancer development.

Opis:
Introduction. The proper negative margins (R0) breadth in the breast - conserving surgery for invasive breast cancer (IBC) and ductal carcinoma in situ (DCIS) is very important. The presence positive surgical margins (R1) is associated with the necessity of reoperation. It delays the adjuvant therapy and psychologically burdens the patient. The re-operation increases the costs of treatment. The introduction of mammography (MMG) increased detection of DCIS by 20%. With the increase in malignancy, cancer detection decreases in MMG, inversely in MRI groving. Effective preoperative and intraoperative diagnosis aims to reduce the number of R1 resections. Aim. The size of the tumor next to its biology, determines the clinical course of the tumor. The accurate analysis of imaging tests is important. Material and methods. This analysis was performed using a systematic literature search. Results. Adequate surgical margins in breast cancer surgery for breast cancer have been reviewed. It is important to know if the cancer is multifocal and what the extent of the tumor is. Conclusion. The adequacy of margins is important for adjusting the volume of excision. It is avoiding unnecessary resection of healthy breast tissue. It is essential for a good cosmetic result and the local recurrence rate. The combination of breast MRI with conventional breast imaging resulted in the lover rate of the R1 resectios and the lower rate of the re-operation.

Opis:
Purpose: To evaluate chosen mucins (mucin 1, 4, 5AC) expression in pancreatic intraepithelial neoplasia, which is a precursor lesion of pancreatic ductal adenocarcinoma. Materials and methods: The study group included 70 patients operated on due to inflammation, cysts and pancreatic ductal adenocarcinoma with pancreatic intraepithelial neoplasia revealed additionally. Mucin 1, 4 and 5AC expression was assessed by immunohistochemical method using polyclonal antibodies. Results: Statistical analysis proved a positive correlation between the expression of mucin 1, 4 and 5AC proteins and the presence and staging of pancreatic intraepithelial neoplasia (p<0.001). Statistically significant correlations were determined between mucin 1, 4 and 5AC and the location of PanIN lesion in the pancreas. Positive correlations were found between mucin 5AC expression and the type of a basic disease (p=0.014). Differences in the expression of MUC 1, 4 and 5AC proteins between healthy pancreatic ducts and various stages of pancreatic intraepithelial neoplasia were statistically significant (p<0.001). Conclusions: Overexpression of mucin 1, 4 and 5AC is related to the presence of pancreatic intraepithelial neoplasia. This suggests that overproduction of mucus is a phenomenon occurring early in the process of carcinogenesis in the pancreas and has its beginning in precancerous lesions of an early stage.
