RESUMO
We aimed to evaluate the efficacy and safety of trastuzumab emtansine in patients with metastatic breast cancer previously treated with pertuzumab plus trastuzumab and taxane. We reviewed the medical records of patients who were diagnosed with Human Epidermal Growth Factor Receptor 2 (HER-2) positive metastatic breast cancer and received pertuzumab and then TDM-1 between January 2014 and January 2021 from twenty- five cancer centers. The Kaplan- Meier method estimated progression-free survival (PFS) and overall survival (OS). Additionally, objective response rate (ORR), clinical benefit rate (CBR), and safety were evaluated. One hundred fifty-three patients were included,79.1% of the patients received TDM-1 in the second line, 90.8% had visceral metastasis, and 30.7% had central nervous system involvement. The PFS and OS of TDM-1 were evaluated according to the number of previous lines (on the 2nd line or more than two lines) metastatic sites (visceral and non-visceral) and the presence of central nervous metastasis. In TDM-1 therapy, PFS in second line therapy was ten months (95% CI: 7.7 - 12.2); this was statistically higher than later-line PFS, which was six months (95% CI: 3.3 to 8.6) (p = 0.004). The median OS time was 25 months (95% CI: 21.0 to 28.9) in patients treated with TDM-1 in the second line and 19 months (95% CI: 12.3 to 25.6) in patients who received later than the second line(p = 0.175). There were no significant differences in PFS time of patients with and without visceral and central nervous metastases. Our study showed that TDM-1 was also effective in patients using pertuzumab, contributes significantly to PFS when used in the second line compared to its use in the later line, and does not make any difference in OS.
RESUMO
Background/aim: The study is aimed to determine the relationship between the delivery and breastfeeding history of the patients and the clinicopathological properties of breast cancer. Materials and methods: A questionnaire was utilized for the study, which included the age of diagnosis, the number of children at the time of diagnosis, the age of the children, and the breastfeeding period of each child. Results: The study included 828 patients. The median age at diagnosis was 47 years for parous women and 42 years for nonparous women (p < 0.001). The tumor size of the patients diagnosed within the breastfeeding period was significantly larger compared to the other patients. Estrogen and progesterone receptor positivity were lower in patients diagnosed during breastfeeding. Additionally, the mean number of positive lymph nodes, dissected lymph nodes, and positive lymph node/dissected lymph node ratio in parous and breastfed patients with a nonmetastatic disease were statistically significantly higher in multivariable analysis than those patients who were nulliparous and have not breastfed. Conclusion: Breast cancer is seen at a later age in patients who are parous than those who have never given birth. Patients who are parous and have breastfed tend to present with a higher stage of the disease.

Objective: Differences in individual muscle/fat volumes may change the effectiveness of chemotherapy. In this study, the relationship between trunkal muscle and fat volume and body mass index (BMI) obtained before receiving neoadjuvant chemotherapy (NCT) in patients with breast cancer and complete pathological response (pCR) was investigated. Materials and Methods: The volumes of psoas, abdominal and paraspinal muscles, and trunkal subcutaneous and visceral fat were calculated using CoreSlicer AI 2.0 opensource program from the F-18 fluorodeoxyglucose positron emission tomography/computed tomography (CT) and CT images before NCT and postoperative pCR rates to NCT were recorded. Muscle/fat volumes and BMI prior to NCT were compared in terms of pathological pCR rates. Patients were followed up regularly for recurrence and survival. Results: Ninety-three patients were included with median (range) values for age, BMI, and body weights of 48 (28-72) years, 27 (16.8-51.6) kg/m2, and 71.94 (43-137) kg, respectively. The median follow-up time was 18.6 (6.7-59.6) months. No significant correlation was found between total muscle or fat volumes of patients with and without pCR. BMI [26.2 (16.8-51.6) kg/m2 vs. 24.6 (20.3-34.3) kg/m2, p = 0.03] and pCR rates in patients with low right-psoas muscle volume [11.74 (7.03-18.51) vs. 10.2 (6.71-13.36), p = 0.025] were significantly greater. A significant relationship was found between right psoas muscle volume and disease-free survival (DFS) (11.74 cm3 (7.03-18.51) vs. 10.2 cm3 (6.71-13.36), p = 0.025). However, no significant relationship was detected between total muscle-fat volume, BMI and overall survival and DFS (p>0.05). Conclusion: This is the first published study investigating the relationship between the pCR ratio and body muscle and fat volume measured by CoreSlicer AI 2.0 in patients with breast cancer who received NCT. No correlation was found between the pCR ratio and total muscle plus fat volume. However, these results need to be validated with larger patient series.
RESUMO
AIM: Epithelial ovarian cancer (EOC) is the most ominous tumor of gynecological cancers due to its poor early detection rate and unfavorable prognosis. To date, there is no reliable screening method for the diagnosis of ovarian cancer at an early stage. MiRNAs are small non-coding RNA molecules, and their main function is to regulate gene expression. The present study compared the serum miR-1181 and miR-4314 levels in patients with EOC and healthy controls to measure the diagnostic and prognostic value as candidate biomarkers. MATERIALS AND METHODS: We collected serum samples from a total of 135 participants (69 patients with EOC and 66 healthy controls). Relative expressions of miR-1181 and miR-4314 were measured by quantitative real-time polymerase chain reaction assay (qPCR). RESULTS: The present study revealed that both serum miR-1181 and miR-4314 levels in patients with EOC were significantly increased compared to healthy controls for each marker. In addition, there was a significant relationship between miR-1181 and miR-4314 overexpressions and the stage and prognosis of the disease. Finally, patients with high expression levels of miR-1181 and miR-4314 had significantly shorter survival rates than those with low expression levels. CONCLUSION: The current study proposed that serum miR-1181 and miR-4314 could discriminate the EOC patients from healthy controls. In addition, both miR-1181 and miR-4314 may be predictive biomarkers for ovarian cancer prognosis. Further studies are needed to confirm the findings of the present study.

BACKGROUND: Surgery remains a priority for breast cancer treatment. This study aimed to compare the cosmetic outcomes of oncoplastic patients who had undergone breast-conserving surgery, mini-LDF (latissimus dorsi flap), and immediate implant reconstruction using both the Japanese scale and the BCCT.core (The Breast Cancer Conservative Treatment cosmetic results software) program and to validate this program. PATIENTS AND METHODS: Patients who underwent surgery for breast cancer between 1997 and 2021 were retrospectively studied. Patients were divided into three groups: 1-those who had undergone breast-conserving surgery (245 patients, 71.3%), 2-those who had undergone mini-LDF after lumpectomy (38 patients, 11.02%), and 3- those who underwent reconstruction with implants after nipple-sparing mastectomy (61 patients, 17.68%). The patients were called for a follow-up examination, and their photos were taken. The photographs were shown to an independent breast surgeon and a plastic surgeon who was not included in the surgeries, and they were asked to evaluate and rate them according to the Japanese cosmetic evaluation scale. The same images were transferred to the computer and scored using BCCT.core. RESULTS: The plastic and breast surgeon evaluation results showed no significant difference between the three cosmetic techniques (p = 0.99, 0.98). The results of BCCT.core software measurements were similar to the results of plastic and breast surgeons (p: 0.43). CONCLUSION: Patients are more knowledgeable about cosmetic outcomes and expect more objective data. In this study, we used 3 different cosmetic evaluation scales. We found that these techniques give results that are compatible with each other in terms of evaluating the work done in a more concrete way. For this reason, we recommend the use of such software, which offers objective results in a subjective field such as aesthetics and is very easy to apply.

BACKGROUND: The goal of this study was to assess the clinicopathologic characteristics and prognostic variables in men with breast cancer (BC). METHODS: Clinical features, pathological characteristics, stage at diagnosis, and therapy data were noted. Survival analysis was performed using the log-rank technique and Cox regression model. RESULTS: Eighty patients were included in the study. In 31% of the individuals, BRCA (BReast CAncer genes 1 and 2) mutations were identified. The estrogen receptor (ER) positivity ratio was 93.6%, whereas the progesterone receptor (PR) positivity ratio was 74.4%. In 16.9% of the cases, HER2 overexpression was found. The median survival time was 120.9 months (70.3-171.5), and the five-year overall survival (OS) ratio was 74.9%. In univariate analysis, BRCA mutation status had no effect on OS (P = 0.50). CA15-3 levels (P = 0.03) at diagnosis and history of smoking (P = 0.03) were significantly linked with OS. However, the multivariate analysis could not confirm these results. CONCLUSIONS: We found that BRCA mutation, body mass index, a history of smoking, and alcohol consumption did not affect the OS in this research.

OBJECTIVE: Central nervous system (CNS) metastasis originating from gynecological cancer is a very rare and late manifestation of the disease. Therefore, there is still limited data on prognostic factors for survival. The objective of the present study is to identify prognostic factors for survival in patients with CNS metastasis originating from gynecological cancer. STUDY DESIGN: The present retrospective study analyzed the patients with gynecological cancers who were treated due to CNS metastases between January 1999 and December 2019 at Istanbul University Hospital. RESULTS: Forty-seven patients with CNS metastasis of gynecological origin were included in the study. The median age at the time of CNS metastasis was 59 (range 34-93). The median time from initial cancer diagnosis to CNS metastasis was 24.9 (range: 0-108.2) months. Most patients had epithelial ovarian cancer (EOC) (76.6%), followed by endometrial cancer (EC) (14.8%), cervical cancer (CC) (4.3%), and vulvar cancer (VC) (4.3%). By multivariate analysis, the presence of extracranial metastasis (HR: 5.10; 95% CI: 1.71-15.18), Eastern Cooperative Oncology Group (ECOG) performance status ≥3 (HR: 2.92; 95% CI: 1.36-6.26), palliative care only for the treatment of CNS metastasis (HR: 1.47; 95% CI: 0.58-4.11), and treatment-free interval (TFI) <6 months (HR: 2.74; 95% CI: 1.23-6.08) were independent factors that associated with worse survival. CONCLUSION: Patients with CNS metastasis who have favorable prognostic factors are considered to be appropriate candidates for aggressive and long-term treatment strategies. Extracranial metastasis, ECOG performance status, treatment history of CNS metastasis, and TFI were determined as independent prognostic factors that improved survival. TFI might be taken into account as a prognostic factor for patients with CNS metastasis in gynecological cancer.
