Abstract
BACKGROUND The effect of multidrug immunosuppressive protocols on the salivary glands is still unknown. This study aimed to determine the influence of immunosuppressive regimens based on calcineurin inhibitors (CNIs) and conversion to rapamycin on the morphology, apoptosis, and proliferation of rat salivary glands. METHODS Male rats received cyclosporin A (CsA), tacrolimus (FK-506), mycophenolate mofetil (MMF), rapamycin (Rapa), and prednisone (Pre) according to three-drug protocols: CMP (CsA, MMF, and Pre), CMP/R (CsA, MMF, and Pre with conversion to Rapa), TMP (FK-506, MMF, and Pre), and TMP/R (FK-506, MMF, and Pre with conversion to Rapa). Morphological and immunohistochemical and quantitative analyses of the salivary glands were performed. RESULTS Structural changes in salivary glands were observed in all experimental groups, especially in the submandibular gland. In the salivary glands, the percentages of collagen fibers and TUNEL-, Ki67- and PCNA-positive cells were higher in the experimental groups vs. the control but were lower in the CMP/R and TMP/R groups vs. the CMP and TMP groups, with the exception of collagen fibers in the parotid gland in the TMP/R group vs. the TMP group. CONCLUSIONS Long-term administration of CNIs in triple regimens and after conversion to rapamycin monotherapy, causes morphological changes in the salivary glands of rats. Immunosuppressive treatment based on CNIs is associated with an increase in collagen accumulation. The effects of the conversion of treatment with CNIs to rapamycin in immunosuppressive protocols in rat salivary glands lead to decreased fibrosis, apoptosis, and proliferation. These changes may possibly prevent abnormalities resulting from the application of CNIs.

Abstract
The guidelines Thyroid Cancer 2022 are prepared based on previous Polish recommendations updated in 2018. They consider international guidelines - American Thyroid Association (ATA) 2015 and National Comprehensive Cancer Network (NCCN); however, they are adapted according to the ADAPTE process. The strength of the recommendations and the quality of the scientific evidence are assessed according to the GRADE system and the ATA 2015 and NCCN recommendations. The core of the changes made in the Polish recommendations is the inclusion of international guidelines and the results of those scientific studies that have already proven themselves prospectively. These extensions allow de-escalation of the therapeutic management in low-risk thyroid carcinoma, i.e., enabling active surveillance in papillary microcarcinoma to be chosen alternatively to minimally invasive techniques after agreeing on such management with the patient. Further extensions allow the use of thyroid lobectomy with the isthmus (hemithyroidectomy) in low-risk cancer up to 2 cm in diameter, modification of the indications for postoperative radioiodine treatment toward personalized approach, and clarification of the criteria used during postoperative L-thyroxine treatment. At the same time, the criteria for the preoperative differential diagnosis of nodular goiter in terms of ultrasonography and fine-needle aspiration biopsy have been clarified, and the rules for the histopathological examination of postoperative thyroid material have been updated. New, updated rules for monitoring patients after treatment are also presented. The updated recommendations focus on ensuring the best possible quality of life after thyroid cancer treatment while maintaining the good efficacy of this treatment.

Abstract
The course of Acanthamoeba spp. infection depends on the age and immune status of the host, and the virulence of the Acanthamoeba spp. strain. Some strains of free-living amoebae exhibit organ specificity, during the course of infection, while others may cause changes
in many organs or completely lose pathogenicity. The aim of the current study was to investigate the pathological properties of Acanthamoeba spp. isolated from a patient with acute myeloid leukemia and atypical pneumonia (AM22). Moreover, the objective was to investigate the histopathological
changes in the kidneys and heart of immunocompetent and immunosuppressed mice infected with Acanthamoeba spp. Amoebae were re-isolated from both the kidneys and hearts of the inoculated mice, although no cysts or trophozoites of the amoebae were detected in microscopic slides of the
fragments of these organs. Acanthamoeba spp. induced changes in the kidney and heart weight of infected mice. In immunocompetent and immunosuppressed Acanthamoeba spp. infected mice, we found some histopathological changes, including areas with less acidic cytoplasm and a relaxation
of muscle fibers. In further studies, it is important to analyze changes in gene and protein expressions in the heart and kidneys of hosts with disseminated acanthamoebiasis to better understand the course of infection in these organs, because the results of histological analysis varied depending
on the immune status and duration of infection.

Abstract
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. We measured maximal metastasis diameter (SLDmax) in the sentinel lymph nodes and lymph node metastasis volume (VALN) from ALND in 246 patients with one or two positive SLNs. We calculated axLCP after irradiation and systemic treatment for different molecular types. Results VALN values are higher for high grade tumours and larger metastases in SLNs (> 5 mm). It is smaller in luminal A tumours. axLCP is high, nearly 100%, in all molecular types in radiation sensitive tumours (SF2 Gy = 0.45), except luminal B. Expected axLCP is relatively low (67%) in luminal B radiation sensitive tumours with no chemotherapy and nearly 100% with chemotherapy. Conclusion VALN values differ among molecular tumour types. They depend on SLNDmax and tumour grade. New prognostic factors are needed for selected luminal B breast cancer patients (i.e. high grade tumours, large metastases in SLNs) after positive SLNB intended to be spared ALND and chemotherapy.

Abstract
The exact mechanism of selective progesterone receptor modulator action in leiomyoma still challenges researchers. The aim of the study was to assess the effects of ulipristal acetate (UPA) on immunoexpression of inflammatory markers and vascularization in fibroids. UPA-treated patients were divided into three groups: (1) good response (≥25% reduction in volume of fibroid), (2) weak response (insignificant volume reduction), (3) and no response to treatment (no decrease or increase in fibroid volume). The percentage of TGFβ, IL6, IL10, CD117, and CD68-positive cells were significantly lower in the group with a good response to treatment vs. the control group. Moreover, the percentage of IL10 and CD68-positive cells in the group with a good response to treatment were also significantly lower compared to the no response group. Additionally, a significant decrease in the percentage of IL10-positive cells was found in the good response group vs. the weak response group. There were no statistical differences in the percentage of TNFα-positive cells and vessel parameters between all compared groups. The results of the study indicate that a good response to UPA treatment may be associated with a decrease of inflammatory markers, but it does not influence myoma vascularization.

Abstract
Melanoma is one of the most aggressive human malignancies. The determination of prognostic biomarkers is important for the early detection of recurrence and for the enrollment of the patients into different treatment regimens. Herein, we report the 10-year survival of 375 melanoma patients depending on their serum selenium levels. The study group was followed up from the date of melanoma diagnosis until death or 2020. Patients were assigned to one of four categories, in accordance with the increasing selenium level (I-IV quartiles). The subgroup with low selenium levels had a significant lower survival rate in relation to patients with high selenium levels, HR = 8.42; p = 0.005 and HR = 5.83; p = 0.02, for uni- and multivariable models, respectively. In the univariable analysis, we also confirmed the association between Breslow thickness, Clark classification and age at melanoma prognosis. In conclusion, a low serum selenium level was associated with an increased mortality rate in the 10 years following melanoma diagnosis. Future studies in other geographic regions with low soil selenium levels should be conducted to confirm our findings.

Abstract
BACKGROUND To this day, the effect of multi-drug immunosuppressive protocols on renal expression of AQPs is unknown. This study aimed to determine the influence of rapamycin-based multi-drug immunosuppressive regimens on the expression of aquaporins (AQPs) 1, 2, 3, and 4 in the rat kidney. METHODS For 6 months, 24 male Wistar rats were administered immunosuppressants, according to the three-drug protocols used in patients after organ transplantation. The rats were divided into four groups: the control group, the TRP group (tacrolimus, rapamycin, prednisone), the CRP group (cyclosporine A, rapamycin, prednisone), and the MRP group (mycophenolate mofetil, rapamycin, prednisone). Selected red cell indices and total calcium were measured in the blood of rats and quantitative analysis of AQP1, AQP2, AQP3 and AQP4 immunoexpression in the kidneys were performed. RESULTS In the TRP and CRP groups, a mild increase of mean corpuscular hemoglobin concentration, hematocrit and total calcium were observed. Moreover, decreased expression of AQP1-4 was found in all experimental groups, with the highest decrease in the CRP group. CONCLUSIONS The long-term immunosuppressive treatment using multi-drug protocols decreased AQP1-4 expressions in renal tubules, possibly leading to impaired urine-concentrating ability in rat.

Abstract
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. We analyzed 1466 patients with negative sentinel lymph node biopsy and no prior systemic treatment. Mastectomy without irradiation was used in 25.4% of these patients and breast-conserving surgery with adjuvant radiotherapy in 74.6%. Forty-seven (3.21%) locoregional relapses were identified within a median of 51 months (10-138 months). The molecular type was analyzed as a risk factor for locoregional relapses and distant metastases. The locoregional relapse location was then analyzed as a risk factor for distant metastases. RESULTS Triple-negative breast cancer (P = .003), age <40 year (P = .007), multifocality (P = .011), and mastectomy (P < .0001) were risk factors for locoregional relapses. Patients who developed locoregional relapses more frequently developed distant metastases (P < .0001). The distribution of molecular types did not differ significantly in patients with locoregional relapses and distant metastases, concentrating in triple-negative and Luminal B tumor cases with distant metastases in almost 58% of cases, while not occurring in Luminal A patients. The locoregional-to-distant metastasis interval was shorter in cases of chest wall and lymph nodes relapse compared with breast-only relapse locations(P = .028). CONCLUSION Molecular type, especially triple-negative, young age, mastectomy without adjuvant irradiation, and multifocality are risk factors for locoregional relapse in sentinel lymph node biopsy negative breast cancer patients. Locoregional relapse is an important risk factor for developing distant metastasis, except in Luminal A breast cancer patients and those who suffer from breast-only relapse.

Abstract
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. In 126 (39%), there were positive additional axillary lymph nodes. Specimens of resected lymph nodes were scanned and the volumes of tumors (expressed as diameter in mm) were calculated. The maximal diameter of metastasis in the sentinel lymph nodes (SLNDmax ) and axillary lymph nodes (ALNDsum ) indicated tumor load in the resected lymph nodes. ALNDsum higher or equal to 5 mm was defined as high and present in 62 patients (21%). RESULTS Risk factors for high ALNDsum were primary tumor diameter (P = 0.0092), histopathological type (P = 0.0173), number of positive SLNs (P = 0.0012), type of metastasis (P = 0.0025), molecular type (P = 0.0037), SLNDmax (P = 0.0001), and Her-2 status (P = 0.0093). Independent variables for high ALNDsum were SLNDmax (P < 0.0001), number of positive SLNs (P = 0.0237) and primary tumor diameter (P = 0.0296). CONCLUSIONS Twenty-one percent patients with positive SLNB are at risk of high ALNDsum . SLNDmax is the strong predictive factor for high ALNDsum after positive ALND.

Abstract
INTRODUCTION The morphology of the endometrium constantly changes in the reproductive period, depending on the levels of ovarian steroid hormones, and undergoes atrophic changes during menopause as a result of their insufficiency. The purpose of this study was to analyze morphological and morphometric changes in the mucous and muscle layers of the uterine wall in postmenopausal women, and to assess localization and number of cells showing the expression of steroid hormone receptors, namely estrogen receptor α (ER-α), progesterone receptor (PR), and androgen receptor (AR) in glandular epithelial cells and smooth muscle cells in particular groups of women. MATERIAL AND METHODS The study material consisted of uterine specimens sectioned across the full thickness of the uterine wall, and embedded in 164 paraffin blocks. The specimens came from women without menopausal hormone therapy (MHT) operated due to reproductive organ prolapse or uterine myomas. The material was divided into four groups depending on the time interval from menopause to surgery: group I - from 1 to 5 years after menopause, group II - from 6 to 10 years after menopause, group III - more than 11 years after menopause, and group IV - women over 70 years of age. The sections were stained by standard HE, Masson's trichrome, and immunohistochemical methods (ERα, PR, AR). Quantitative assessment of the results was based on computer image analysis. RESULTS Analysis of morphological changes in the endometrium and myometrium revealed the presence of increasing regressive changes, such as various types of atrophy, fibrosis, and calcification, augmented over time from the last menstruation. Furthermore, endometrial polyps, foci of endometriosis, and leiomyomas were observed. Based on the results of morphometric measurements, a constant decrease in the endometrial and myometrial thickness was noticed in the studied groups (I-IV). Significant differences between the groups were observed in the number of ER-α positive cells in the myometrium, but not in the endometrial glandular epithelium. Statistically significant differences in the number of AR positive cells were detected in the endometrial epithelium and in the uterine muscle. The analysis the number of PR positive cells demonstrated differences between the groups in the endometrial stroma and the myometrium. CONCLUSION The uterus of postmenopausal woman undergo major morphological changes (mainly atrophic lesions in the endometrium and myometrium), leading to a decline in their morphometric parameters over time from the last menstruation. Localization and number of cells showing the expression of steroid receptors: ER-α, PR, and AR in the uterus of postmenopausal women, depending on the time interval from the last menstruation.

Abstract
The association of BRCA1/2 mutations with melanoma is not completely determined; the interpretation of variants of unknown significance is also problematic. To evaluate these issues we explored the molecular basis of melanoma risk by performing whole-exome sequencing on a cohort of 96 unrelated Polish early-onset melanoma patients and targeted sequencing of BRCA1/2 genes on additional 30 melanoma patients with familial aggregation of breast and other cancers. Sequencing was performed on peripheral blood. We evaluated MutationTaster, Polyphen2, SIFT, PROVEAN algorithms, analyzed segregation with cancer disease (in both families with identified BRCA2 variants) and in one family performed LOH (based on 2 primary tumors). We found neither pathogenic mutations nor variants of unknown significance within BRCA1. We identified two BRCA2 variants of unknown significance: c.9334G>A and c.4534 C>T. Disease allele frequency was evaluated by genotyping of 1230 consecutive melanoma cases, 5000 breast cancer patients, 3500 prostate cancers and 9900 controls. Both variants were found to be absent among unselected cancer patients and healthy controls. The MutationTaster, Polyphen2 and SIFT algorithms indicate that c.9334G>A is a damaging variant. Due to lack of tumour tissue LOH analysis could not be performed for this variant. The variant segregated with the disease. The c.4534 C>T variant did not segregate with disease, there was no LOH of the variant. The c.9334G>A variant, classified as a rare variant of unknown significance, on current evidence may predisposes to cancers of the breast, prostate and melanoma. Functional studies to describe how the DNA change affects the protein function and a large multi-center study to evaluate its penetrance are required.

Abstract
Purpose Germline mutations within melanoma susceptibility genes are present only in minority of melanoma patients and it is expected that additional genes will be discovered with next generation sequence technology and whole-exome sequencing (WES). Materials and Methods Herein we performed WES on a cohort of 96 unrelated Polish patients with melanoma diagnosed under the age of 40 years who all screened negative for the presence of CDKN2A variants. A replication study using a set of 1,200 melanoma patient DNA samples and similarly large series of healthy controls was undertaken. Results We selected 21 potentially deleterious variants in 20 genes (VRK1, MYCT1, DNAH14, CASC3, MS4A12, PRC1, WWOX, CARD6, EXO5, CASC3, CASP8AP2, STK33, SAMD11, CNDP2, CPNE1, EFCAB6, CABLES1, LEKR1, NUDT17, and RRP15), which were identified by WES and confirmed by Sanger sequencing for an association study. Evaluation of the allele distribution among carriers and their relatives in available family trios revealed that these variants were unlikely to account for many familial cases of melanoma. Replication study revealed no statistically significant differences between cases and controls. Conclusion Although most of the changes seemed to be neutral we could not exclude an association between variants in VRK1, CREB3L3, EXO5, and STK33 with melanoma risk.

Abstract
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. We also aimed to verify how changes in our protocol influenced the frequency of WBRT. Material and methods Between April 20, 2010 and May 10, 2017, we identified 207 patients irradiated with IORT for APBI. Results Ninety-one patients (44%) met the criteria for APBI only, while 116 (56%) should have been offered additional WBRT. Retrospective analysis showed that WBRT was applied statistically significantly less frequently compared with strict protocol indications: 99 patients (47.8%) received APBI only and 108 (51.2%) underwent adjuvant WBRT (p < 0.0001). Applying the TARGIT trial guidelines, 69 patients (33.4%) should have been offered WBRT (p < 0.0001), which is twice the number of patients treated with WBRT in our study. Changing the protocol to less restrictive criteria would have statistically significantly decreased the number of patients (95, 46%) offered WBRT (p < 0.0001). Conclusions Following international guidelines, 46% of patients should receive WBRT after IORT, which is 1.5-2 times more than for the TARGIT criteria. In our analysis, a high percentage of patients (19%) did not receive WBRT after IORT despite the protocol recommendations. The chosen protocol strongly influences the frequency of adjuvant WBRT.

Abstract
INTRODUCTION Apoptosis and proliferation of prostate cells are associated with both physiological increase and hyperplasia of the prostate. The aim of this study was to determine the contribution of metabolic syndrome to the processes of apoptosis and proliferation in gland epithelial cells and prostatic stromal cells in men with BPH. SUBJECTS AND METHODS The study involved 151 men, aged 52-89 years, receiving pharmacological treatment for BPH. The men were divided into two groups: those with and those without metabolic syndrome. The serum levels of the parameters were determined. Reactions for the identification of apoptosis (TUNEL) and proliferation (PCNA) in cells were also performed. RESULTS The relationships between the number of TUNEL(+) and PCNA(+) cells and metabolic syndrome were not observed. It was found that the total number of TUNEL(+) cells in the prostate stroma correlated negatively with the levels of high-density lipoprotein and insulin-like growth factor-1. The analysis of the correlations in BPH patients with and without metabolic syndrome demonstrated that the only parameter correlating with the number of PCNA(+) cells in the prostate stroma was insulin resistance. CONCLUSION Metabolic syndrome in patients with BPH had no impact on the number of TUNEL(+) and PCNA(+) cells in the prostate gland. However, the disturbed levels of metabolic parameters, and deviations of anthropometric parameters from normal may influence the number of apoptotic and proliferating cells.

Abstract
INTRODUCTION Standard pre-operative diagnosis of nodular goitre is not always conclusive. The decision about nodular goitre surgery is increasingly based on molecular methods. The aim of the study was to determine BRAF T1799A mutation and KRas proto-oncogene mutation, and the analysis of RASSF1A promoter methylation level in cytological material obtained from FNAB specimens of thyroid nodules. MATERIAL AND METHODS The study population consisted of 85 women and 12 men. The study material was genomic DNA isolated from peripheral blood and thyroid bioptates. Pyrosequencing was used for the evaluation of RASSF1 methylation level. KRas mutation was investigated with Sanger sequencing. BRAF mutation was analysed by standard methods of real-time amplification detection (real-time PCR) with the use of specific starters surrounding the mutated site. RESULTS A significant positive correlation was demonstrated between mean methylation of four CpG islands of RASSF1A gene and thyroid tumour volume and its largest diameter (p < 0.05). KRas mutation was not detected in any of the 97 patients. In 7/85 subjects (8.2%) BRAF mutation was observed. In 6/7 patients with BRAF mutation, FNAB of thyroid nodules confirmed a benign nature of the lesions; the material was non-diagnostic in one patient, and papillary thyroid cancer was diagnosed on the basis of postoperative histopathology assessment. CONCLUSIONS The results of genetic tests reported in our study indicate that the presence of BRAF mutation or higher RASSF1A methylation levels in FNAB cytology specimens of benign lesions may be useful in the assessment of oncological risk, while the evaluation of KRas proto-oncogene mutation is not a valuable test in pre-operative diagnosis of nodular goitre.

Abstract
The aim of this study was to determine the influence of different combinations of immunosuppressive drugs on the morphology, ultrastructure, and expression of proliferating cell nuclear antigen and cytoskeleton proteins in the rat dorsolateral prostate. The studies were conducted on 48 male Wistar rats. The animals were divided into eight groups: a control group and seven experimental groups. For 6 months, the animals in the experimental groups were administered a combination of drugs including rapamycin (Rapa), cyclosporin A, tacrolimus (Tac), mycophenolate mofetil, and prednisone (Pred), according to the standard three-drug regimens for immunosuppressive therapy used in clinical practice. An evaluation of the morphology and ultrastructure was conducted, and a quantitative evaluation of the expression of proliferating cell nuclear antigen and desmin- and cytokeratin-positive cells with weak, moderate, and strong expression was performed. The combination of Rapa, Tac, and Pred caused the smallest morphological and ultrastructural changes in the rat prostate cells. In the case of rats whose treatment was switched to Rapa monotherapy, a decreased percentage of proliferating cells of both the glandular epithelium and the stroma was found. Decreases in body weight and changes in the expression of cytokeratin and desmin were observed in all the experimental rats. The combination of Rapa, Tac, and Pred would seem to be the most beneficial for patients who do not suffer from prostate diseases. Our results justify the use of inhibitors of the mammalian target of Rapa in the treatment of patients with prostate cancer. The changes in the expression of cytoskeleton proteins may be the result of direct adverse effects of the immunosuppressive drugs, which are studied in this article, on the structure and organization of intermediate filament proteins.

Abstract
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. AIM In this study, we analyze risk factors for seroma evacuation more than 6 months after IORT. MATERIALS AND METHODS We evaluated 120 patients with a mean follow-up of 27.8 months (range: 7-52 months). Fifty-one patients received IORT only and 69 were additionally treated with WBRT. RESULTS Seroma evacuation was performed 6-38 months after IORT. Two (3.9%) events were observed in the IORT group and 14 (20%) in the IORT + WBRT group. Univariate (Kaplan-Meier) analysis showed that addition of WBRT to IORT increased the risk of seroma evacuation [hazard ratio = 5.5, 95% confidence interval: 2.0-14.7, P = 0.011]. In a multivariate analysis (Cox proportional hazards regression), WBRT and axillary lymph node dissection were significant risk factors for seroma evacuation (model P value = 0.0025). CONCLUSIONS WBRT applied after IORT is associated with increased risk of seroma evacuation, which might be considered as a late side effect.

Abstract
AIM Analysis of the impact of immunosuppressants on apoptosis and PCNA in the rat ventral prostate. METHOD The studies were performed on 48 male Wistar rats. The animals were divided into a control group and 7 experimental groups. For 6 months, the rats were administered drugs such as: rapamycin (Rapa), cyclosporin A (CsA), tacrolimus (Tac), mycophenolate mofetil (MMF) and glucocorticosteroids (GS). During section of the rats, prostate ventral lobes were obtained. Morphological evaluation (HE, PAS), TUNEL assay, PCNA expression analysis and quantitative image computer analysis were performed. RESULTS The highest percentage of apoptosis in epithelial cells was observed in groups which received two combinations of drugs: (V) CsA, MMF, GS and (VII) Tac, MMF, GS. A much lower percentage of apoptotic epithelial cells was found in the groups where the treatment schemes included rapamycin throughout the duration of the study. Interestingly, the conversion of the treatment to rapamycin caused a significant reduction of apoptosis in epithelial cells as well as in proliferation in both epithelial and stromal cells. CONCLUSIONS On one hand, the obtained results may explain the anticancer activity of rapamycin in reducing the proliferation of epithelial cells, and on the other hand the adverse effect of rapamycin in the form of reduced regeneration of these cells. Taking into account the prostate in isolation from other organs/systems, the dosage scheme with Rapa, Tac and GS would appear to be the most favorable, due to the smallest morphological changes.

Abstract
The first case of a female neonate born from an in vitro fertilization with embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI) (IVF-ET (ICSI) with two histologically different tumours (craniopharyngioma and hepatoblastoma) is described. Anti-neoplasmatic therapy was abandoned due to the significant extent of the disease (craniopharyngioma, 15 x 12 cm in diameter with active internal hydrocephalus; and right liver lobe hepatoblastoma, 5 cm in diameter) and the severely impaired general condition of the neonate. The neonate died on the 30th day of life due to cerebellar and brainstem herniation, followed by circulatory and respiratory failure.

Abstract
AIMS To distinguish signet-ring cancer cells from foamy macrophages in the small gastric endoscopic biopsies using objective morphometric measurements of nuclei. MATERIAL AND METHODS Using computerized image analysis, the mean nuclear area, length, breadth, perimeter and roundness were analyzed in histological sections of ten gastric endoscopic biopsies with signet-ring cell adenocarcinoma and four benign lesions with numerous foamy macrophages. RESULTS Nuclei of signet-ring cell adenocarcinoma were significantly bigger than nuclei of foamy macrophages. Mean nuclear area (34.25 μm2 for carcinoma cells vs. 25.41 μm2 for macrophages) and mean nuclear breadth (5.82 μm vs. 4.99 μm, respectively) differed significantly (P < 0.05), whereas the remaining parameters did not. CONCLUSION Nuclear morphometry can distinguish foamy macrophages from signet-ring cell adenocarcinoma cells in endoscopic gastric biopsies.

Abstract
BACKGROUND The aim of this study was to analyze the occurrence of clinical features characteristic of breast cancer type 1 susceptibility protein (BRCA-1)-dependent tumors in a series of BRCA-1 mutation carriers with laryngeal cancer. PATIENTS AND METHODS The clinical features of five laryngeal cancer patients with BRCA-1 mutations registered in our center were analyzed for: sex, age at diagnosis, age at operation, tumor size and localization, histopathological subtype and grading, lymph node and distant metastases, mode of treatment and long term results of the therapy. RESULTS The five patients were all men, with an average age at diagnosis of 52.4 years. The majority of the patients had clinical features typical of BRCA-1-dependent tumors: four out of the five patients had advanced staging at the time of diagnosis and in three of them the disorder disseminated within one year of follow-up. CONCLUSION Since laryngeal carcinomas in men with BRCA-1 mutations show clinical features characteristic of BRCA-1 dependent tumors, it is reasonable to consider treatment modifications appropriate for this sub-group of tumors.

Abstract
The aim of this study was to evaluate associations between seven morphometric parameters of the nucleoli and nuclei of methyl green and pyronin Y (MG-PY) stained tumour cells of invasive ductal breast carcinoma with relapse-free survival (RFS) and overall survival (OS) time. Histological sections from 150 invasive ductal breast cancers were stained with MG-PY and the following parameters were evaluated by computer image analysis: the nucleolar area, long to short nucleolar axis ratio, nucleolar shape parameter assessing the degree of nucleolar roundness, long to short nuclear axis ratio, number of nucleoli in the nucleus and the percentage of the nuclear cross-section surface area occupied by the nucleoli. A statistically significant association between a nucleolar shape polymorphism and the number of nucleoli in the nuclei of tumour cells and the RFS but not OS was found in the entire group of patients as well as patients with axillary lymph node metastases. A higher polymorphism of nucleolar shape and a higher number of nucleoli in the nuclei of breast cancer cells were associated with decreased relapse-free survival (p < 0.05). The remaining morphometric parameters showed no statistically significant association with RFS or OS. The results indicate that morphometry of nucleoli in MG-PY stained histological sections can be useful in the analysis of associations between nucleolar parameters and prognosis of patients with invasive breast cancer.

Abstract
The search for the genomic sequences involved in human cancers can be greatly facilitated by maps of genomic imbalances identifying the involved chromosomal regions, particularly those that participate in the development of occult preneoplastic conditions that progress to clinically aggressive invasive cancer. The integration of such regions with human genome sequence variation may provide valuable clues about their overall structure and gene content. By extension, such knowledge may help us understand the underlying genetic components involved in the initiation and progression of these cancers. We describe the development of a genome-wide map of human bladder cancer that tracks its progression from in situ precursor conditions to invasive disease. Testing for allelic losses using a genome-wide panel of 787 microsatellite markers was performed on multiple DNA samples, extracted from the entire mucosal surface of the bladder and corresponding to normal urothelium, in situ preneoplastic lesions, and invasive carcinoma. Using this approach, we matched the clonal allelic losses in distinct chromosomal regions to specific phases of bladder neoplasia and produced a detailed genetic map of bladder cancer development. These analyses revealed three major waves of genetic changes associated with growth advantages of successive clones and reflecting a stepwise conversion of normal urothelial cells into cancer cells. The genetic changes map to six regions at 3q22-q24, 5q22-q31, 9q21-q22, 10q26, 13q14, and 17p13, which may represent critical hits driving the development of bladder cancer. Finally, we performed high-resolution mapping using single nucleotide polymorphism markers within one region on chromosome 13q14, containing the model tumor suppressor gene RB1, and defined a minimal deleted region associated with clonal expansion of in situ neoplasia. These analyses provided new insights on the involvement of several non-coding sequences mapping to the region and identified novel target genes, termed forerunner (FR) genes, involved in early phases of cancer development.

Abstract
BACKGROUND The aim of the study was analysis at both the level and the cell site of the sodium/iodide symporter (NIS) in histological slides from hot, warm, and cold nodules and extranodular parenchyma according to scintigraphy. METHODS The study population consisted of 97 people who underwent surgery for a toxic nodular goiter (26 patients) or a non-toxic nodular goiter (71 patients). Immunohistochemical study was performed with 198 histological slides from hot, warm, and cold nodules (study slides) and the extranodular parenchyma (control slides). The level of NIS expression was estimated objectively using the computerized image analysis system, Quantimet 600S (Leica, Cambridge, UK). RESULTS We found significantly higher NIS expression in hot nodules than in cold nodules and in warm nodules than in cold ones. We found significantly higher NIS expression in hot and warm nodules than in the surrounding parenchyma. The level of NIS expression did not differ significantly between cold nodules and the collateral tissues. CONCLUSIONS Our data indicate that NIS protein participates in the development of hyperthyroidism in the course of a nodular goiter. We confirm that the functional state of a nodular goiter is determined by NIS expression in nodules, not in collateral parenchyma. The low metabolism of cold nodules does not simply result from decreased level of NIS protein or its defective targeting to the cell membrane. The observation of NIS in the cell cytoplasm of hot nodules seems to indicate that the intracellular localization of NIS does not determine loss of its activity.

Abstract
UNLABELLED THE AIM of the study was an evaluation of the relationship between histological chorioamnionitis and cord blood soluble intercellular adhesion molecule-1 (sICAM-1) and CRP levels. MATERIAL AND METHODS in the group of 152 neonates observed for early onset infection (clinical and laboratory signs) the relationship between histological chorioamnionitis and cord blood sICAM-1 (ELISA) and CRP (turbidimetric method) levels was assessed. All these newborns were born in the years 2002-2004 to mothers with risk factors of perinatal infection. RESULTS histological chorioamnionitis (ChA) was found in 50 cases, while early onset infection signs occurred in 112 neonates. The percentage of ill and healthy newborns in group with ChA and without ChA was similar. There were significantly higher sICAM-1 (p<0.001) levels in neonates from pregnancy complicated with ChA than without ChA (179 +/- 68.7 v. 147 +/- 30.8 ng/ml). There was not such difference in the CRP levels. There was also a significant positive correlation between cord blood sICAM-1 and ChA in the whole analyzed group of patients (r=0.26; p<0.001) and in the group of ill neonates (r=0.37; p<0.0001). There was a significant difference (p<0.001) in sICAM-1 levels between ill and healthy neonates from the group with ChA (191,8 +/- 73.9 v. 143,4 +/- 31.9 ng/ml) but not without ChA. No difference was found in sICAM-1 levels between groups of healthy neonates born after pregnancy complicated and not complicated with ChA. CONCLUSIONS coexistence of ChA and early onset infection in neonates enhanced the cord blood sICAM-1 levels. Healthy newborns born from pregnancy complicated by ChA do not react by increasing cord blood sICAM-1 levels. It is not possible to exclude early onset infection in neonates on the basis of normal cord blood sICAM-1 levels, because ill newborns born after pregnancy not complicated with ChA also do not react with increasing sICAM-1 production at birth.

Abstract
In this paper, we present whole-organ histologic and genetic mapping studies using hypervariable DNA markers on chromosome 13 and then integrate the recombination- and single-nucleotide polymorphic sites (SNPs)-based deletion maps with the annotated genome sequence. Using bladders resected from patients with invasive urothelial carcinoma, we studied allelic patterns of 40 microsatellite markers mapping to all regions of chromosome 13 and 79 SNPs located within the 13q14 region containing the RB1 gene. A whole-organ histologic and genetic mapping strategy was used to identify the evolution of allelic losses on chromosome 13 during the progression of bladder neoplasia. Markers mapping to chromosomal regions involved in clonal expansion of preneoplastic intraurothelial lesions were subsequently tested in 25 tumors and 21 voided urine samples of patients with bladder cancer. Four clusters of allelic losses mapping to distinct regions of chromosome 13 were identified. Markers mapping to the 13q14 region that is flanked by D13S263 and D13S276, which contains the RB1 gene, showed allelic losses associated with early clonal expansion of intraurothelial neoplasia. Such losses could be identified in approximately 32% bladder tumor tissue samples and 38% of voided urines from patients with bladder cancer. The integration of distribution patterns of clonal allelic losses revealed by the microsatellite markers with those obtained by genotyping of SNPs disclosed that the loss within an approximately 4-Mb segment centered around RB1 may represent an incipient event in bladder neoplasia. However, the inactivation of RB1 occurred later and was associated with the onset of severe dysplasia/carcinoma in situ. Our studies provide evidence for the presence of critical alternative candidate genes mapping to the 13q14 region that are involved in clonal expansion of neoplasia within the bladder antecedent to the inactivation of the RB1 gene.

Abstract
In the present paper, morphological and functional features of human sperm midpiece, contributing to the assessment of sperm fertility potential, have been described. The NADH-dependent NBT screening assay was used to identify and visualise: 1/ morphological defects of sperm midpiece, 2/ immature sperm forms with extensive cytoplasmic retention, reflecting developmental failure in spermatogenic remodelling process, 3/ cytoplasmic sperm conglomerates, related to apoptotic bodies and 4/ sperm NADH-dependent oxidoreductase system at the mitochondrial level, related to the reaction intensity. The used assay is an adequate marker of sperm mitochondrial activity and sperm maturity. It can also help discover sperm defects that result in asthenozoospermia and can be used as an additional indicator in the evaluation of the sperm midpiece, as well as in routine morphological examination of spermatozoa, having a considerable predictive value for in vivo and in vitro fertilization.

Abstract
The effect of hyperprolactinaemia on the prostate has still not been fully elucidated. The aim of the study was to estimate the influence of hyperprolactinaemia on expression of the androgen receptor (AR) in rat epithelial cells of the prostate lateral lobe and on the morphology of these cells. Studies were performed on sexually mature male Wistar rats. To provoke hyperprolactinaemia rats received i.p. metoclopramid (MCP). For light and electron microscopy the lateral lobes were obtained routinely. The intensity of the immunohistochemical reaction of AR (expression of AR) in the epithelial cells of the prostate lateral lobe was assessed by optical density measurements with the help of computer image analysis. Ultrastructural observations of the epithelial cells of the lateral lobe were carried out by means of transmission and scanning electron microscopes. The results showed a more than twofold increase in prolactin (PRL) concentration in the serum, but a twofold decrease in testosterone (T). The intensity of the immunohistochemical reaction of AR in the epithelial cells of the lateral lobe in the experimental group was higher than in the control group. We noted changes in the morphology of the epithelial cells of the prostate lateral lobe in the experimental group.

Abstract
The purpose of this study was to define the value of angiogenesis as a prognostic factor indicating early relapse. We assessed the relationship between parameters of angiogenesis (microvessel count--MVC, microvessel area--MVA and microvessel perimeter--MVP) and relapse-free survival at 50 months in 226 women with invasive ductal breast carcinoma. Anti CD31 antibody was used as a marker of endothelial cells. Microvessel density was measured according to Weidner et al. using a computerised image analysis. The mean parameters of angiogenesis were significantly higher in women with relapse than in those without recurrence within 50 months after surgery. In node negative patients relapse did not occur if MVC was below 38.7. In node-negative subgroup with grade II carcinomas parameters of angiogenesis in the primary tumour differed significantly depending on the presence or absence of relapse. Univariate and multivariate analysis showed the prognostic value of angiogenesis parameters in all study groups with respect to 50-month relapse-free survival. In node negative subgroup only 62.5% of women with tumors with high MVC and as much as 94.9% with low MVC survived 50 months without recurrence. In the Cox analysis of node-negative subgroup only MVC, MVP and MVA were the independent prognostic factors. In women with node-negative disease the evaluation of angiogenesis can identify a subgroup of patients with high risk of relapse, hence it may help in decisions concerning adjuvant therapy. Computerised image analysis is a good and objective technique for evaluating the intensity of angiogenesis in breast cancer.

Abstract
The purpose of our study was to determine the effect of dilution and liquid-preservation of boar sperm on oxidoreductive capability of their mitochondria. The semen was diluted with BTS extender produced from water purified by destillation or by reverse osmosis. The spermatozoa were stored over a four-day period at 16-18 degrees C. The function of sperm mitochondria was assessed using the screening cytochemical test for NADH-dependent oxidoreductases (diaphorase/NADH, related to flavoprotein). Morphological assessment of cytochemical reaction was carried out using a light microscope. The intensity of the reaction was evaluated by means of a computer image analysing system (Quantimet 600S), measuring the integrated optical density (IOD) and mean optical density (MOD) of the reaction product (formazans) occurring in the sperm midpieces. In the non-diluted semen, intensive cytochemical reaction throughout the length of the sperm midpiece was observed. Furthermore, spermatozoa with the intensive reaction displayed the high optical density values. After dilution the semen with two variants of experimental extender, and as the conservation time expired, the cytochemical reaction was less intensive. Moreover, the absence of formazan deposits in various parts of the sperm midpiece was also noted. These morphological features corresponded to low values of optical density. These findings suggest that the dilution of semen and the time of sperm preservation may be critical factors that handicap energy metabolism of sperm mitochondria. The type of water used in preparing BTS extender does not have any significant effect on the oxidoreductive capability of sperm boar mitochondria.

Abstract
The purpose of the study was to correlate angiogenesis parameters (microvessel count, area and perimeter) with some clinical and morphological factors in 251 invasive ductal breast carcinomas in women. Endothelium was stained with antiCD31 antibody, and measurements were made using a computerised image analysis in the whole study population and separately for two subgroups with and without metastases to axillary lymph nodes. High angiogenesis parameters in primary tumours were associated with older age, large tumour diameter, high grade and the associations were statistically significant. Furthermore the microvessel density was significantly higher in tumours metastasising to lymph nodes as compared with tumours without metastases. Microvessel perimeter was found to be the most useful of vessel parameters analysed. The correlation between angiogenesis and some clinical and morphological parameters, especially lymph node status may indicate the prognostic value of angiogenesis in invasive ductal breast carcinomas.

Abstract
We report two rare examples of dermal fibrohistiocytic stromal tumors: one case of atypical fibrous histiocytoma (AFH) and another one of atypical fibroxanthoma (AFX), which can be confused in surgical pathology diagnosis with high-grade malignant neoplasm. Histologically, a proliferation of mononuclear, spindle-shaped, or histiocytoid cells and/or multinucleated cells, usually admixed with inflammatory cells was observed in both cases, but some clinicopathological differences allowed their distinction. Immunohistochemistry is of a little help in differential diagnosis between these two entities however, it is very useful in differentiating with other groups of tumors. Recognition of AFH and AFX is important, especially to prevent incorrect aggressive treatment in those cases that may be confused with high-grade sarcoma. Because of the potentially aggressive behavior in rare cases and the lack of clear-cut predictive morphologic patterns that would specify a poor clinical outcome, complete surgical excision in all cases is recommended.

Abstract
Histologic and genetic mapping with 30 hypervariable markers mapped to chromosome 16 were performed on 234 DNA samples of five cystectomy specimens from patients with invasive bladder cancer. Allelic losses of individual markers were related to microscopically identified precursor conditions in the entire bladder mucosa and invasive cancer. Their significance for the development and progression of neoplasia from in situ preneoplastic conditions to invasive disease was analysed by the nearest neighbor algorithm and binomial maximum likelihood analysis. Using this approach we identified five distinct regions of allelic losses defined by their flanking markers and predicted size as follows. p13.3(D16S418-D16S406, 1.2 cM), p13.1(D16S748-D16S287, 12.9 cM), q12 1(D16S409-D16S514, 24.0 cM), q22.1 (D16S496-D16S515, 5.4 cM), and q24 (D16S507-D16S511, 5.9 cM and D16S402-D16S413, 17.4 cM). The regions mapping to p13.1 and q24 were involved in early intraurothelial phases of bladder neoplasia such as mild to moderate dysplasia. On the other hand the deleted region mapping to p13.3 was involved in progression of severe dysplasia/carcinoma in situ to invasive bladder cancer. Testing of markers that exhibited statistically significant LOH in relation to progression of neoplasia from precursor conditions to invasive cancer on 28 tumors and voided urine samples from 25 patients with bladder cancer revealed that q12.1 showed LOH in 46.4% of tumor and 32.0% of voided urine samples. The LOH of a single marker D16S541 could be detected in approximately 28% of tumors and 20% of voided urine samples of patients with bladder cancer. These data imply that the deleted region centered around marker D16S541 spanning approximately 10 cM and flanked by D16S409 and D16S415 contains a novel putative tumor suppressor gene or genes playing an important role in the development of human bladder cancer. To facilitate more precise positional mapping and identification of pathogenetically relevant genes, we analysed of human genome contig and sequence databases spanning the deleted regions. Multiple known candidate genes and several smaller gene-rich areas mapping to the target regions of chromosome 16 were identified.

Abstract
We studied the evolution of allelic losses on chromosome 5 by whole-organ histologic and genetic mapping in 234 mucosal DNA samples of 5 cystectomy specimens with invasive bladder cancer and preneoplastic changes in adjacent urothelium. The frequency of alterations in individual loci was verified on 32 tumors and 29 voided urine samples from patients with bladder cancer. Finally, deleted regions on chromosome 5 were integrated with the human genome contigs and sequence-based databases. Deleted regions on chromosome 5 involved in intraurothelial phases of bladder neoplasia defined by their nearest flanking markers and predicted size were identified as follows: q13.3-q22 (D5S424-D5S656; 38.8 centimorgan [cM]); q22-q31.1 (D5S656-D5S808; 19.2 cM), q31.1-q32 (D5S816-SPARC; 11.5 cM), and q34 (GABRA1-D5S415; 6.4 cM). The two most frequently deleted neighbor markers (D5S2055 and D5S818) mapping to q22-q31.1 defined a 9 cM region, which may contain genes that play an important role in early phases of urinary bladder carcinogenesis. Human genome database analysis provided an accurate map of deleted regions with positions of 138 known genes and revealed several smaller gene-rich areas representing putative targets for further mapping. The strategic approach presented here, which combines whole-organ histologic and genetic mapping with analysis of the rapidly emerging human genome sequence database, facilitates identification of genes potentially involved in early phases of bladder carcinogenesis.

Abstract
The relationship between proliferating cell nuclear antigen (PCNA) expression and clinical stage, lymph node status, histological grade, malignancy index (MI) [13] were studied in 103 laryngeal squamous cell carcinomas (SCC). The PCNA index (the percentage of PCNA positive nuclei) was examined immunohistochemically using monoclonal PC10 antibody on paraffin sections. PCNA immunoreactivity was seen in all samples with mean value of PCNA index 37.4% for supraglottic and 36.8% for glottic SCC. The PCNA index was significantly related to histological grade and malignancy index (p < 0.05). For all tumors no correlation was found between PCNA index and clinical stage and lymph node status however, metastasizing glottic SCC had higher PCNA index than non-metastasizing ones. The modification of MI in glottic laryngeal SCC by adding PCNA index as a new parameter is proposed.

Abstract
We examined 59 breast cancers for p53 and bcl-2 protein expression by immunohistochemistry. The results were correlated with Ki-67 immunostaining. p53-negativity was noted in 40 cases and the remaining 19 tumours were p53-positive. Thirty-six tumours showed strong expression of bcl-2 and in 23 no staining for this protein was observed. We found statistically significant reverse correlation between expression of p53 and bcl-2 in majority of carcinomas: 31 cases were bcl-2 positive and p53-negative, and 14 tumours were bcl-2-negative and p53-positive. Six carcinomas showed no nuclear staining for Ki-67 and in the remaining 53 the percent of cancer cells positive for Ki-67 ranged from 1 to 60 (mean: 14.6). In these 53 cases we found that bcl-2-positive tumours were characterized by lower proliferation than bcl-2-negative tumours, the mean value of Ki-67 immunostaining being 10.7% and 23.0%, respectively. p53-negative tumours showed lower proliferation than p53-positive tumours: mean Ki-67 index was 10.2% and 23.9%, respectively. We conclude that immunohistochemically detected p53 and bcl-2 proteins show a significant inverse relationship in majority of breast carcinomas and their expression correlates with tumour proliferation (Ki-67 immunostaining).

Abstract
The predominant mode of either spontaneous or drug-induced death of cells in tumors is apoptosis. A flow cytometric method was developed in our laboratory to identify apoptotic cells, based on labeling DNA strand breaks, which appear as a result of extensive DNA cleavage by the apoptosis-associated endonuclease, with biotinylated dUTP in the reaction catalyzed by exogenous terminal deoxynucleotidyl transferase. The aim of this study was to reveal whether this methodology can be applied to human solid tumors sampled by fine-needle biopsy. Twenty-two tumors, consisting of 11 breast carcinomas; three metastatic anaplastic carcinomas; three adenocarcinomas of colon, endometrium, and lung; two metastatic lymph node squamous cell carcinomas of the larynx; and three malignant lymphomas were examined. It was possible to identify cells with DNA strand breaks in all these tumors. Extremely high variability in the proportion of cells with DNA strand breaks was observed between the individual tumors. In diploid tumors (n = 12) the percentage of cells with DNA strand breaks varied from 1% to 43%, and the mean value was 19%. In aneuploid tumors this percentage varied from 15% to 51% and the mean value was 37%. In the latter tumors the presence of cells with DNA strand breaks was limited to the DNA aneuploid cell population; very few diploid, presumably tumor infiltrating or stromal cells, showed the presence of DNA strand breaks. No correlation was observed between the percent of cells in S phase and those with DNA strand breaks. The data indicate that apoptosis is more frequent in populations of tumor cells than among normal cells of the same organs.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This report describes the fine needle aspiration (FNA) cytologic findings in 17 rare malignant breast tumors. The series consisted of invasive cribriform carcinoma, papillary carcinoma, apocrine carcinoma, carcinoma with pseudosarcomatous metaplasia, carcinosarcoma, fibrosarcoma, malignant phyllodes tumors, primary malignant lymphomas, plasmocytoma, metastatic melanoma and metastatic renal clear cell carcinoma. Besides cytomorphology, the results of immunostaining in eight cases are presented, as is a review of the literature. It is important for rare primary malignancies, as well as for metastatic tumors, to be diagnosed, or at least have the diagnosis suggested, preoperatively by FNA and immunocytochemistry, permitting better therapy planning.

Abstract
La France disease of the cultivated mushroom, Agaricus bisporus, is known to be associated with the presence of a number of dsRNA segments. The nucleotide sequences of the dsRNAs M2 (1.3 kb), M1 (1.55 kb) and L3 (2.8 kb), invariably associated with the disease, were determined. Putative coding sequences for proteins with molecular weights of 38, 40 and 87 kDa were found for M2, M1 and L3 dsRNAs, respectively. The average G + C content of these dsRNAs was 43%, close to that of A. bisporus nuclear DNA. The nucleotide sequences, as well as the amino acid sequences, appear to be unique, as no matching sequences could be found among databases. S3 dsRNA (0.39 kb), which is occasionally found in large amounts in diseased mushrooms, is an internally deleted variant of M2 dsRNA and is largely composed of the non-coding ends of that dsRNA.

Abstract
A simplified method of processing of fine needle aspirates for paraffin miniblocks suitable for both morphologic and immunocytochemical evaluation is described. Aspirates were fixed in ethanol at 4 degrees C, dehydrated in acetone and xylene and embedded in paraffin (58 degrees C). All steps were carried out in a single Eppendorf centrifuge tube; the total process took less than four hours. Deparaffinized sections were stained using the alkaline phosphatase-antialkaline phosphatase technique with monoclonal and conventional antibodies helpful in the differential cytologic diagnosis of alcohol-fixed aspiration biopsy specimens. Antibodies to keratin, vimentin, desmin, neurofilaments, glial fibrillary acidic protein, leukocyte-common antigen, synaptophysin and immunoglobulin kappa and lambda light chains reacted positively on the miniblock material. Since the paraffin miniblocks combine the histologic pattern of the tumor with the differentiation-specific information provided by immunocytochemistry, their use can improve the accuracy of tumor typing in aspirates.

Abstract
The oncogenes most frequently detected in human tumors belong to the ras gene family (Ha-ras, Ki-ras, and N-ras). These genes encode a group of closely related 21,000 dalton proteins termed p21. An immunohistochemical study of ras p21 expression was carried out on paraffin sections of 54 human breast carcinomas using monoclonal antibodies to p21. The control group consisted of ten cases of benign fibrocystic disease. The p21 expression was significantly higher in cancer cells than in epithelial cells of control specimens. No correlations, however, were observed between oncogene product expression and tumor size, histologic type, or grade. As a group, tumors with axillary lymph node metastases expressed higher levels of ras p21 than nonmetastasizing tumors. However, because of the significant overlap in individual p21 values, it is unlikely that the immunohistochemical assay for p21 could be used to predict the behavior of mammary carcinomas.
