A Systematic Review Investigating the Difference between 1 Cycle versus 2 Cycles of Adjuvant Chemotherapy in Stage I Testicular Germ Cell Cancers.

Standard care for stage I testicular germ cell cancers (seminomatous-STC or non-seminomatous-NSTC) is orchiectomy followed by active surveillance, 1 or 2 cycles of adjuvant chemotherapy, surgery or radiotherapy. The decision on the adjuvant therapeutic approach is guided by the associated risk factors of the patient and the potential related toxicity of the treatment. Currently, there is no consensus regarding the optimal number of adjuvant chemotherapy cycles. Although in terms of overall survival, there is no proven inconsistency regarding the number of cycles of adjuvant chemotherapy, and the rate of relapse may vary.

Absolute and Functional Iron Deficiency in Colon Cancer: A Cohort Study.

Background and Objectives: Iron is an essential micronutrient for many biological functions and has been found to be intimately linked to cancer biology. Although the effects of increased dietary iron consumption in the development of CRC have been previously investigated in several cohort studies, the available evidence on the involvement of iron deficiency in this process is relatively scarce. Previously published papers did not analyze specific outcomes, such as the presence of biologically aggressive histopathological characteristics, that are associated with the subtypes of iron deficiency. The purpose of this study was to investigate the connection between the development of colorectal cancer and the presence of functional iron deficiency (FID), which is defined as insufficient biological availability of iron in the presence of adequate storage reserves, or absolute iron deficiency (AID), which is defined as severely depleted iron storage levels. Materials and Methods: Our paper represents a single center registry-based cohort study. Iron levels were routinely evaluated upon diagnosis of CRC and the collected data were coupled with patient- and tumor-specific data (2018-2022). Spearman's correlation coefficient and the chi-squared test were used to analyze the association. Results: Out of 129 patients, 75 (58.13%) were anemic. AID was identified in 26.35% of cases and FID was encountered in 51.16% of cases. A statistically significant association between FID and lymphatic invasion was encountered. An analysis of the correlation demonstrated a significant association between anemia and right-sided tumor location. Conclusions: Functional iron deficiency seems to be independently associated with lymphatic invasion. Although a statistically significant correlation with the T or N stage was not demonstrated, the analysis suggested a potential positive relationship between the presence of FID and more aggressive tumor characteristics.

T4 retroperitoneal liposarcoma. Challenges of big size sarcomas surgical treatment.

Our article presents some of the challenges of the surgical treatment of T4 (>15 cm) retroperitoneal liposarcomas (up to 65∕56∕30 cm, 25.5 kg) series of cases treated by the Department of Surgical Oncology, Prof. Dr. Ion Chiricuta Oncology Institute, Cluj-Napoca (IOCN), Romania, with illustrations, insisting on important blood vessels and nerves dissection and preservation and discussions of strategies with references to important articles from the last 10 years specialty literature. Challenges do not come only from intraoperative difficulties but also from establishing the right attitude from the extent of resection and oncological safety point of view, the role of the pathologist being very important because histological subtype and completeness of the resections are the most important prognostic factors for such tumors. Despite all today available aids in decision making, like nomograms or high-resolution imagery, sometimes this decision is to be taken intraoperative based on surgeon's expertise and skills. That is why is strongly advised that such cases to be treated in high-volume specialized tertiary centers of surgical oncology.
