[Borderline ovarian tumors and global radiation in relation with climate change impact]. / Tumorile ovariene cu potential malign scazut si radiatia globala.

UNLABELLED: There is limited information on borderline ovarian tumor detected intra-surgically and its most favorable treatment in relation with global radiation and climate changes. AIM: To study the pre-surgery and intra-surgery differentiation criteria of borderline ovarian tumors from invasive carcinoma, and to make a very complex analysis of the frequency, distribution, and variation in time of global radiation, temperature, and precipitation in North-East Romania. MATERIAL AND METHOD: The 54 patients (age range 20-78 years, mean age 46 years) included in this study had borderline ovarian tumors surgically treated during the last 22 years (January 1988 - December 2009) at the 4th Gynecological Clinic at Iasi, and representing 4.87% of the total 1107 ovarian tumors detected and treated during this interval. The histological types were: serous (18 cases), mucinous (27 cases), mixed (8 cases), and Brenner tumor (1 case). In order to analyze the impact of climate changes on borderline ovarian tumors a thorough study on the frequency of global radiation in relation with climate changes based on data recorded in the last 55 years was also carried out. RESULTS: The distribution of these cases depending on when surgery was performed was analyzed. In our study the frequency of ovarian borderline tumors (4.87%) is lower than in similar reports in the literature being due, in our opinion, to the influence of global radiation in relation with climate changes. CONCLUSIONS: In our study global radiation is probably responsible for a progression to invasive carcinoma in 0.7% of the borderline ovarian tumors.

[Ovarian tumors of low malignant potential (borderline ovarian tumors)]. / Tumorile ovariene cu potential malign scazut (tumorile ovariene borderline).

UNLABELLED: Ovarian borderline tumors are rare, their good prognosis depending on their stage at the time of diagnosis, and the presence of invasive implants. There is little information on tumor type identified intra-surgically, as well as on the most favorable treatment in borderline ovarian tumors. AIM: To determine the criteria of identification and presurgery and intra-surgery differentiation of the ovarian borderline tumors from the invasive carcinoma and benign ovarian tumors. MATERIAL AND METHODS: This study included 54 patients with TPMS (ovarian borderline tumors) surgically treated in the past 22 years (January 1988-December 2009) at the 4th Gynecological Clinic of the lasi "Gr. T. Popa" University of Medicine and Pharmacy. In this interval 1,107 ovarian tumors: 575 benign, 478 malignant, and 54 TPMS (4.87%) were recorded. The age of the patients with borderline tumors ranged between 20 and 78 years, mean age 46 years, and the histological types were: mucinous (27 cases), serous (18 cases), mixed (8 cases), and Brenner tumor (1 case). RESULTS: We have analyzed the distribution of these cases according to the time when surgical treatment was performed. The frequency of borderline ovarian tumors in our study is 4.87%, lower than in the literature. We believe that this low percentage in our study is due to missing the microscopic data in some macroscopic benign tumors. CONCLUSIONS: By this research we aimed at elaborating a therapeutic strategy for each case using with discernment the modern treatment (surgery, chemotherapy, radiotherapy), as well as new chemical drugs with the goal of obtaining better results and longer survival. There are no tumor markers which could predict the progression of a borderline ovarian tumor to invasive tumors, but the invasive course is only 0.7%.
