ABSTRACT

Background/Objectives: Recently, some new morphological features of colorectal cancer have been discovered as important prognostic factors; in this paper, we study the relationship between tumor budding (TB) and tumor deposits (TDs). Methods: The retrospective cohort study included 90 patients with pathohistologically confirmed stage III CRC who were treated with radical surgical resection. All hematoxylin and eosin (H and E)-stained slides from each patient were reviewed, and histological parameters were recorded. The samples were divided into two groups with similar sizes: a group without TDs (N = 51) and a control group with TDs (N = 39). The presence and TB grade were further analyzed in these groups and compared with other clinical and histological features. Results: The prevalence of TB in the investigated cohort was unexpectedly high (94.4%). Overall, there were 23 (25.6%) Bd1, 20 (22.2%) Bd2, and 47 (52.2%) Bd3 cases. The presence of TDs was significantly associated with a higher number of TB (p < 0.001, OR 16.3) and, consequently, with a higher TB grade (p = 0.004, OR 11.04). A higher TB grade (p = 0.001, HR 2.28; 95% CI 1.93-4.76) and a growing number of TDs (p = 0.014, HR 1.52; 95% CI 1.09-2.1) were statistically significantly associated with shorter survival. Conclusions: TDs appear more often in patients with higher TB grades in stage III CRC. A higher TB grade and a growing number of TDs were statistically significantly associated with shorter overall survival. These results could give additional emphasis to the importance of TB as an adverse prognostic factor since a strong relationship with TDs has been demonstrated.

ABSTRACT

The aim of this study was to analyze the TNM classification factors of invasive breast cancer that can be affected by the national program for early detection of breast cancer in the Republic of Croatia. The other analyzed factors related to histology and immunohistochemistry have no such impact as they are related to biological behavior and aggressiveness of malignant breast tumors, thus providing useful predictive and prognostic information. The study was performed at Department of Oncologic Surgery, Sestre milosrdnice University Hospital Center, and included 75 patients surgically treated for invasive breast cancer during the period of one month in 2011, mean age 64 +/- 11.36 (range 36-86) years. Most of the patients (68%) with malignant breast disease were diagnosed in a localized stage, which is consistent with the reports from developed European countries. The size of the newly discovered tumors showed continuation of a trend of detecting tumors of ever less size and a lower percentage of pT3 pT4 tumors. This result proved superior to those reported from many European countries. The results of correlation analysis, tumor size, estrogen and progesterone receptor, HER-2 protein, Ki-67, and histologic tumor grade, tumor size did not show significant correlation with any of these parameters. Concordant expression of phenotype (ER+, PR+) receptor pairs and negative HER-2 was recorded in most study patients. The second most frequent group had tumors with so-called 'triple-negative' immunohistochemistry negative phenotype (ER-, PR-, HER-2). In conclusion, the program of early detection of breast cancer in the Republic of Croatia and at the University Hospital for Tumors justifies its existence for revealing malignant breast tumors at an earlier stage of the disease considering the size local stage of newly diagnosed tumors.

ABSTRACT

AIMS AND BACKGROUND: This study was aimed at analyzing metastatic involvement in interpectoral (Rotter's) lymph nodes in relation to tumor location, size, grade and hormone receptor status in primary breast cancer. METHODS: The study included 172 female patients undergoing surgery for breast cancer at the University Hospital for Tumors, Zagreb, Croatia from November 2001 to August 2003. In addition to the standard surgical procedure, interpectoral (Rotter's) lymph nodes were removed in all of the patients. Serum levels of the tumor marker CA 15-3 were determined before surgery and hormone receptor status after surgery. RESULTS: Rotter's lymph nodes were identified in 67% of the patients, with metastatic involvement being found in 20% of the Rotter's nodes. Metastatic involvement of Rotter's nodes in patients with negative and positive axillary lymph nodes was 4% and 35%, respectively. When we looked at the location of the tumor in patients with metastatic involvement of Rotter's nodes, we found that tumors located in the upper quadrants were more prone to metastasis to Rotter's nodes; there was a significant positive correlation between tumor location and positive Rotter's nodes (r = 0.953, P = 0.012). As regards tumor size, Rotter's nodes were identified in 15%, 20% and 30% of stage T1 (< 2 cm), T2 (2-5 cm) and T3 (> 5 cm) tumors, respectively. Hormone receptor status showed no statistically significant difference in the expression of estrogen and progesterone receptors between patients with and those without positive Rotter's nodes. Of 35 Rotter's node-positive patients, 31.4% had elevated serum levels of CA 15-3; the level was significantly higher in Rotter's-positive patients compared to those with negative (or absent) Rotter's nodes. CONCLUSIONS: The results show that one-fifth of breast cancer patients, or even one-third of those with positive axillary lymph nodes, are discharged with positive interpectoral lymph nodes that remain undiagnosed. As the nodes can be surgically removed without additional mutilation, exploration of Rotter's lymph nodes should be introduced into routine clinical practice.
