In this environment, the tumor stroma represents one of the TME components (1–4). Tumor cells explore their stroma, changing its composition in a bi-directional communication, leading to the stromatogenesis. The interaction pathways are varied and complex. Therefore, the stromal tissue is not a passive component that involves the tumor (5). Studies have shown that tumor stroma plays a relevant and diverse role in tumorigenesis, acting in different stages: it facilitates the survival and proliferation of neoplastic cells; promotes epithelial-mesenchymal transition, and local and metastatic spread (6–12). Even in distant and lymph node metastatic sites, stromal components accompany cancer cells (13, 14). In malignant epithelial tumors, the scoring system based on the evaluation of the tumor-stroma proportion (TSP) in sections stained with hematoxylin and eosin (H&E) has been shown to be a good prognostic tool (9,10,15–18). Several international research groups have demonstrated that high amount of stroma contributes to a more aggressive tumor phenotypes (8, 9, 15–17, 19–21). Their goal was to fill the need for and identify new prognostic characteristics that could be used along with the current pathological staging (8, 20). The traditional tumor, lymph node and metastasis (TNM) system that has been used routinely for prognosis estimate and guidance of treatment for certain types of tumors (22, 23), lacks accuracy (21, 24, 25). In colorectal cancer (CRC), new reliable biomarkers are needed to guide personalized treatment (21) since current pathological variables only moderately indicate possible outcome and response to therapy (6, 19, 21). Currently, CRC represents a serious public health problem worldwide, occupying the third place in terms of incidence and the second place in mortality numbers (22), while being little attended by public policies in underdeveloped or developing countries (26). Although the complete biological role of stroma is not yet fully understood (20), in the last 10 years the evaluation of tumor stroma has gained interest due to its simplicity and, above all, to its clinical value as a potential prognostic factor. Furthermore, cancer cells and stroma are being considered as therapeutic targets in treatment strategies for solid tumors (14), in which the quantification of the stromal component may provide additional risk stratification for adaptation to neoadjuvant and adjuvant treatments (8, 15, 20, 27). The aim of this study was to evaluate the relevance of the tumor-stroma proportion and its association with confirmed aggressive phenotypes in a large series of patients diagnosed with cancer of the right/left colon and r","PeriodicalId":35645,"journal":{"name":"Archive of Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68403410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Age-specific incidence of colon cancer among the > 20 years old adults that were diagnosed from 2006-2015 was analyzed using data from Cancer Registries of the Sabac Public Health Institute and Public Health Institute of Serbia. Linear model of the incidence rates and annual change in age-standardized incidence rates, by sex and age were presented. Standardized incidence ratio, based on average age-specific incidence rates of colon cancer for Sabac municipality and Central Serbia was calculated. Results: Based on the results from our study, colon cancer incidence in Sabac municipality increased in males and females in the last ten years. Risk of developing colon cancer in males and females, calculated by standardized rates ratios was 1.5 and 1.3, respectively. Linear, rising trend for age-standardized incidence rates in the population of Sabac compared to other municipalities in the Macva district was recorded. Furthermore, standardized incidence ratios for both females and males were higher compared to data from Central Serbia (28% and 22%, respectively).

In majority of cases they are found to be 10-80 mm in diameter and do not cause any symptoms. Paraovarian cysts can be found unexpectedly during an operation or on ultrasound examination performed for other reasons. They are most freequently discovered on ultrasound examination. However, due to the proximity of the ovary for which cystic formations are not rare, the diagnosis of these lesions can be a challenge. They are mostly asymptomatic and only large lesions (?20 cm in diameter) become symptomatic. Although these are mostly benign tumors, in rare cases they can become borderline or true malignancies. Most paraovarian cysts are found in the third and fourth decade of life. Paraovarian cyst complications include: compression of the surrounding structures of the pelvis minor and abdomen, pelvic pain, cyst torsion and rupture. Except for the already mensioned complications available literature has so far failed to show cases of uterine prolapse caused by an increase of intra-abdominal pressure due to the expansive growth of giant paraovarian cystic formation.","PeriodicalId":35645,"journal":{"name":"Archive of Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68402635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six months later, the patient underwent the third surgery. The patient is currently receiving another cycle of radiotherapy, and is scheduled for additional cycles of chemotherapy. Ependymomas are the most common spinal cord malignancy in adults. The symptoms are nonspecific which often causes a delay in diagnosis. An MRI examination of the spine with contrast admission is the study of choice for detecting spinal cord masses. Surgery is the first-line therapy for ependymomas. Recurrence rate is associated with the extent of surgical resection, with en bloc and gross-total resection being associated with lower rates of disease recurrence.
