Assessment of Hospital Volume in the Surgical Management of Endometrial and Ovarian Cancer: A Polish Population-Based Study.

BACKGROUND Surgery is a cornerstone in management of ovarian and endometrial cancer. The European Society of Gynecological Oncology introduced quality indicators to improve management of these cancers. The optimal annual number of surgeries per unit was established for high-quality surgical treatment. MATERIAL AND METHODS The database of the National Health Fund on surgical management of endometrial and ovarian cancer was analyzed. Patients treated between 2017 and 2020 were included. Departments where patients underwent surgery were divided according to number of surgeries performed per year in endometrial cancer: ≥80, 79-50, 49-20, 19-0; and ovarian cancer: ≥100, 99-50, 49-20, 19-0. Optimal number of surgeries per center was defined as at least 100 and 80 surgeries per year in ovarian and endometrial cancer, respectively. RESULTS Totally, there were 22 325 surgeries in 316 units and 10 381 surgeries in 251 units due to endometrial and ovarian cancer, respectively. Most surgeries in endometrial cancer (n=15 077; 67.5%) and ovarian cancer (n=9642; 92.88%) were performed in departments that did not meet optimal criteria in number of surgeries. Between 2017 and 2019, an increasing trend in number of surgeries per year in endometrial and ovarian cancer was found. In 2020, there was a decrease in the number of surgeries by 7.8% (n=453) and 8.6% (n=234) in endometrial and ovarian cancer, respectively. CONCLUSIONS In Poland, surgical treatment of ovarian and endometrial cancer is decentralized. Most cancer patients underwent surgery in low-volume general gynecologic departments. The COVID-19 pandemic impaired cancer management, leading to a decreased number of surgeries.

Fertility-Sparing Treatment in Gestational Choriocarcinoma: Evaluating Oncological and Obstetrical Outcomes in Young Patients.

BACKGROUND Gestational choriocarcinoma (GC) is an uncommon neoplasia that occurs in women who may not have completed a procreation plan. The aim of this study was to evaluate oncological and obstetrical outcomes in young patients with GC after fertility-sparing treatment. MATERIAL AND METHODS The eligibility criteria for the study were histopathological diagnosis of GC, age ≤40 years, and treatment with systemic chemotherapy. Patients who underwent upfront hysterectomy were excluded. The response to treatment was assessed according to beta-human chorionic gonadotropin (beta-hCG) serum measurement. Complete response and progression were considered if the beta-hCG dropped to a normal range and increased (or reached a plateau), respectively. The birth rate was calculated as the number of women who gave birth after treatment divided by the total number of patients. RESULTS A total of 18 patients fulfilled the study's eligibility criteria. A complete response and progression to first-line chemotherapy were found in 13 (72.22%) and 5 (27.78%) patients, respectively. Salvage treatment was administered to patients with progression. Overall, 16 (88.88%) patients achieved complete response after treatment and 2 (11.12%) died. GC relapse was diagnosed in 1 patient 62 months after treatment. The birth rate was 22.22%, and a total of 6 children were born. All pregnancies ended in term delivery. No congenital abnormalities were detected in the newborns. CONCLUSIONS GC is a life-threatening form of gestational trophoblastic neoplasia, mainly due to its rapid course and resistance to chemotherapy. Most patients with GC will not be able to bear children after treatment.

Prognostic Factors for Uterine Sarcoma and Carcinosarcoma: Insights from a 10-Year Follow-Up Study.

BACKGROUND Uterine sarcomas and carcinomas are rare tumors and treatment outcomes are far from expected. We investigated the prognostic significance of selected serum biomarkers and the impact of some clinical and tissue factors on overall survival (OS) at 10-year follow-up. MATERIAL AND METHODS The material for analysis was a group of 34 patients with uterine sarcomas and 18 with carcinomas. Immunohistochemistry was performed to determine Ki 67, p53 and ER and PR. Concentrations: CA 125, IL8, VEGF, SFTL1, VEGF R2, sTNFRI and MMP-9 were determined in the serum of patients before treatment and in the control group. RESULTS The most frequently elevated levels observed of sTNF RI in 94% and VEGF in 62%. On the ROC curve analysis, sTNF RI and VEGF concentrations showed the highest sensitivity. Patients with striated cell sarcoma, smooth cell sarcoma and high-grade rhabdomyosarcoma had the worst prognosis. Patient age, FIGO stage and expression of Ki67, p53, ER and PR, CA 125 (p<0.038) and IL-8 (p<0.024) were statistical prognostic factors for OS. However, in multivariate analysis, serum levels of: CA 125 concentration (p<0.045), age (p<0.010) and p53 expression (p<0.014) were found to be significant independent prognostic factors. CONCLUSIONS A 10-year follow-up of patients with uterine sarcoma indicates that age above 60 years at diagnosis and high p53 expression and elevated CA125 levels before treatment can be independent prognostic factors. The high diagnostic sensitivity of sTNF RI and VEGF suggests the possibility of using these biomarkers in the early diagnosis of uterine sarcomas.

Second-line lenvatinib in patients with recurrent endometrial cancer.

OBJECTIVE: This study assessed the efficacy of lenvatinib, a multitargeted tyrosine kinase inhibitor, as second-line therapy in patients with unresectable endometrial cancer. The primary end point was the objective response rate (ORR) as assessed by independent radiologic review (IRR). Secondary end points included median progression-free survival (PFS), overall survival (OS), and clinical benefit rate. Exploratory end points examined the association of baseline levels of plasma biomarkers (50 circulating cytokine and/or angiogenic factors measured by immunoassays) with efficacy outcomes. METHODS: An international, open-label, single-arm, multicenter, phase 2 trial was conducted. Eligible patients had histologically confirmed unresectable endometrial cancer that relapsed after 1 prior systemic platinum-based chemotherapy. Patients received once-daily oral lenvatinib 24 mg in a 28-day dosing cycle. RESULTS: There were 133 patients in the study. By IRR, 19 patients had a confirmed objective response for an ORR of 14.3% (95% CI: 8.8-21.4). Durable stable disease (≥23 weeks) was observed in 31 patients (23.3%) and the clinical benefit rate was 37.6% (95% CI: 29.3-46.4). Median PFS was 5.6 months (95% CI: 3.7-6.3), and median OS was 10.6 months (95% CI: 8.9-14.9). The most common (any grade) treatment-related adverse events were fatigue/asthenia (48%), hypertension (49%), nausea/vomiting (32%), decreased appetite (32%), and diarrhea (31%). Lower baseline levels of angiopoietin-2 were associated with longer PFS, OS, and a higher ORR. CONCLUSIONS: Patients with recurrent endometrial cancer treated with second-line lenvatinib experienced modest antitumor activity and treatment was generally well tolerated, with a safety profile consistent with previous studies.

An evaluation of the construction of the device along with the software for digital archiving, sending the data, and supporting the diagnosis of cervical cancer.

Cervical cancer is still an important cause of mortality among women in a number of countries. There are effective methods of prevention and early diagnosis, but they require well-trained medical professionals including cytologists. Within this project, we built a prototype of a new device together with implemented software using U-NET and CNN architectures of neural networks (ANN), to convert the currently used optical microscopes into fully independent scanning and evaluating systems for cytological samples. To evaluate the specificity and sensitivity of the system, 2058 (2000 normal and 58 abnormal samples) consecutive liquid-based cytology (LBC) samples were analysed. The observed sensitivity and specificity to distinguish normal and abnormal samples was 100%. We observed slight incompatibility in the evaluation of the type of abnormality. The use of ANN is promising for increasing the effectiveness of cervical screening. The low cost of neural network usage further increases the potential areas of application of the presented method. Further refinement of neural networks on a larger sample size is required to evaluate the software.

Somatic mutation profiling of vulvar cancer: Exploring therapeutic targets.

BACKGROUND: Vulvar squamous cell carcinoma (VSCC) constitutes over 90% of vulvar cancer. Its pathogenesis can follow two different pathways; high risk human papillomavirus (hrHPV)-dependent and HPV-independent. Due to the rarity of VSCC, molecular mechanisms underlying VSCC development remain largely unknown. The study aimed to identify pathogenic mutations implicated in the two pathways of VSCC development. METHODS: Using next generation sequencing, 81 VSCC tumors, 52 hrHPV(+) and 29 hrHPV(-), were screened for hotspot mutations in 50 genes covered by the Ion AmpliSeq Cancer Hotspot Panel v2 Kit (Thermo Fisher Scientific). RESULTS: Mutations of TP53 (46% and 41%, of hrHPV(+) and hrHPV(-) cases respectively) and CDKN2A (p16) (25% and 21%, of hrHPV(+) and hrHPV(-) cases respectively) were the most common genetic alterations identified in VSCC tumors. Further mutations were identified in PIK3CA, FBXW7, HRAS, FGFR3, STK11, AKT1, SMAD4, FLT3, JAK3, GNAQ, and PTEN, albeit at low frequencies. Some of the identified mutations may activate the PI3K/AKT/mTOR pathway. The activation of mTOR was confirmed in the vast majority of VSCC samples by immunohistochemical staining. CONCLUSIONS: Detecting pathogenic mutations in 13/50 genes examined at comparable frequencies in hrHPV(+) and hrHPV(-) tumors suggest that genetic mechanisms of the two routes of VSCC pathogenesis may be similar, despite being initiated from different premalignant lesions. Importantly, our data provide a rationale for new anti-VSCC therapies targeting the PI3K/AKT/mTOR pathway.

Normalizers for microRNA quantification in plasma of patients with vulvar intraepithelial neoplasia lesions and vulvar carcinoma.

The role of circulating microRNAs as a promising tool for diagnosing cancer and monitoring anticancer therapies has been widely studied in the past decades. To date, no suitable reference microRNAs for normalizing quantitative real-time polymerase chain reaction assays has been identified in vulvar intraepithelial neoplasia lesions and vulvar squamous cell carcinoma. The purpose of this study was to select appropriate references for gene expression studies in plasma of patients with these lesions. Expression levels of six microRNAs-hsa-miR-425-5p, hsa-miR-191-5p, hsa-miR-93-5p, hsa-miR-423-5p, hsa-miR-103a-3p, and hsa-miR-16-5p-were analyzed by quantitative reverse transcription polymerase chain reaction in plasma samples obtained from 17 patients with vulvar intraepithelial neoplasia lesion and 27 patients with vulvar squamous cell carcinoma. The expression stability of these candidate normalizers was assayed using geNorm algorithm. hsa-miR-93-5p was revealed as the most stably expressed reference in plasma samples of both vulvar intraepithelial neoplasia lesion and vulvar squamous cell carcinoma patients. The results pointed at hsa-miR-93-5p and hsa-miR-425-5p as microRNAs that retained the greatest robustness in plasma of vulvar intraepithelial neoplasia lesion and vulvar squamous cell carcinoma patients, respectively. Our work is the first report on reference microRNA selection for quantitative real-time polymerase chain reaction applications in vulvar intraepithelial neoplasia lesion and vulvar squamous cell carcinoma. The candidate microRNA stability values for the two types of lesions are provided and might serve for normalization of the future novel microRNA biomarkers in these rare entities.

European Society of Gynaecological Oncology Guidelines for the Management of Patients With Vulvar Cancer.

OBJECTIVE: The aim of this study was to develop clinically relevant and evidence-based guidelines as part of European Society of Gynaecological Oncology's mission to improve the quality of care for women with gynecologic cancers across Europe. METHODS: The European Society of Gynaecological Oncology Council nominated an international development group made of practicing clinicians who provide care to patients with vulvar cancer and have demonstrated leadership and interest in the management of patients with vulvar cancer (18 experts across Europe). To ensure that the statements are evidence based, the current literature identified from a systematic search has been reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group (expert agreement). The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 181 international reviewers including patient representatives independent from the development group. RESULTS: The guidelines cover diagnosis and referral, preoperative investigations, surgical management (local treatment, groin treatment including sentinel lymph node procedure, reconstructive surgery), radiation therapy, chemoradiation, systemic treatment, treatment of recurrent disease (vulvar recurrence, groin recurrence, distant metastases), and follow-up.

The assessment of overall survival (OS) after adjuvant chemotherapy for patients with malignant endometrial cancer in Poland.

OBJECTIVES: In 2013 malignant endometrial cancers have amounted to 7.3% of all cancers diagnosed among women in the report by the Polish National Cancer Registry Raw prevalence rate amounted to 28.7, whereas standardised prevalence rate 15.6 per 100 000 population. Among the causes of death, these cancers amounted to 3% and were ranked ninth on the list of the most common causes of oncologic mortality of women. In the year 2013 a total of 1243 women died of malignant endometrial cancers. A stable increase of malignant endometrial cancer incidence has been observed for 2 decades. Despite that fact, the increase of the mortality incidence is at a much lower level, which demonstrates the much higher effectiveness of the treatment of such cancers. The recording rate of the malignant endometrial cancer mortality amounts to 95%, so the presented absolute numbers are reliable. Examining the clinical stages of malignant endometrial cancers, we can establish that approx. 85% of them are diagnosed at stage I or II according to the FIGO classification. Patients with advanced stages of cancer represent less than 15%. MATERIAL AND METHODS: retrospective analysis of endometrial body cancer prevalence data for the entire population of Poland, assessment of malignant endometrial cancer prevalence in the years 2008-2015 and overall survival probability in the population of patients undergoing adjuvant chemotherapy. RESULTS: The number of patients with a diagnosed malignant endometrial cancer within the studied period in Poland remains on a stable level (2008 - 30.6 thousand patients, 2015 - 40.2 thousand patients). Among all listed patients with the indica-tion of C54 each year approx. 20% enters hospital treatment. System therapy with chemotherapy drugs was used in approx. 1-2% of patients treated in hospitals. The average age of the patients was 64.9 years, and the median age 65 years. The num-ber of observations was 2085, including 1088 censored observations. The average survival for the sample under study was 30.67 month (SD = ± 0.6); median survival time was 23.93 month. The number of censored observations was 1088 (52.16%). Probable survival of 1 year is achieved by 67.57% of patients, 2 years by 49.73%, 3 years by 40.68%, above 5 years 30.77%. CONCLUSIONS: The incidence of endometrial cancer in Poland in the years 2008-2015 continues to grow at 5% upward trend (in Europe 3.4-5.9). In Poland in 2012, crude incidence rate for cancer of the uterus was 29.8 and did not differ significantly from the results in countries such as Finland, Slovakia, Sweden, Belgium and Bulgaria. The overall survival after adjuvant chemotherapy for patients with malignant endometrial cancer in Poland shows considerable differences depending on the region of the country.

Standard first-line chemotherapy with or without nintedanib for advanced ovarian cancer (AGO-OVAR 12): a randomised, double-blind, placebo-controlled phase 3 trial.

BACKGROUND: Angiogenesis is a target in the treatment of ovarian cancer. Nintedanib, an oral triple angiokinase inhibitor of VEGF receptor, platelet-derived growth factor receptor, and fibroblast growth factor receptor, has shown activity in phase 2 trials in this setting. We investigated the combination of nintedanib with standard carboplatin and paclitaxel chemotherapy in patients with newly diagnosed advanced ovarian cancer. METHODS: In this double-blind phase 3 trial, chemotherapy-naive patients (aged 18 years or older) with International Federation of Gynecology and Obstetrics (FIGO) IIB-IV ovarian cancer and upfront debulking surgery were stratified by postoperative resection status, FIGO stage, and planned carboplatin dose. Patients were randomly assigned (2:1) via an interactive voice or web-based response system to receive six cycles of carboplatin (AUC 5 mg/mL per min or 6 mg/mL per min) and paclitaxel (175 mg/m(2)) in addition to either 200 mg of nintedanib (nintedanib group) or placebo (placebo group) twice daily on days 2-21 of every 3-week cycle for up to 120 weeks. Patients, investigators, and independent radiological reviewers were masked to treatment allocation. The primary endpoint was investigator-assessed progression-free survival analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01015118. FINDINGS: Between Dec 9, 2009, and July 27, 2011, 1503 patients were screened and 1366 randomly assigned by nine study groups in 22 countries: 911 to the nintedanib group and 455 to the placebo group. 486 (53%) of 911 patients in the nintedanib group experienced disease progression or death compared with 266 (58%) of 455 in the placebo group. Median progression-free survival was significantly longer in the nintedanib group than in the placebo group (17·2 months [95% CI 16·6-19·9] vs 16·6 months [13·9-19·1]; hazard ratio 0·84 [95% CI 0·72-0·98]; p=0·024). The most common adverse events were gastrointestinal (diarrhoea: nintedanib group 191 [21%] of 902 grade 3 and three [<1%] grade 4 vs placebo group nine [2%] of 450 grade 3 only) and haematological (neutropenia: nintedanib group 180 [20%] grade 3 and 200 (22%) grade 4 vs placebo group 90 [20%] grade 3 and 72 [16%] grade 4; thrombocytopenia: 105 [12%] and 55 [6%] vs 21 [5%] and eight [2%]; anaemia: 108 [12%] and 13 [1%] vs 26 [6%] and five [1%]). Serious adverse events were reported in 376 (42%) of 902 patients in the nintedanib group and 155 (34%) of 450 in the placebo group. 29 (3%) of 902 patients in the nintedanib group experienced serious adverse events associated with death compared with 16 (4%) of 450 in the placebo group, including 12 (1%) in the nintedanib group and six (1%) in the placebo group with a malignant neoplasm progression classified as an adverse event by the investigator. Drug-related adverse events leading to death occurred in three patients in the nintedanib group (one without diagnosis of cause; one due to non-drug-related sepsis associated with drug-related diarrhoea and renal failure; and one due to peritonitis) and in one patient in the placebo group (cause unknown). INTERPRETATION: Nintedanib in combination with carboplatin and paclitaxel is an active first-line treatment that significantly increases progression-free survival for women with advanced ovarian cancer, but is associated with more gastrointestinal adverse events. Future studies should focus on improving patient selection and optimisation of tolerability. FUNDING: Boehringer Ingelheim.

The assessment of the prognostic value of tumor markers and cytokines as SCCAg, CYFRA 21.1, IL-6, VEGF and sTNF receptors in patients with squamous cell cervical cancer, particularly with early stage of the disease.

The aim of this study is to determine the prognostic value of tumor markers, as squamous cell carcinoma antigen (SCCAg) and cytokeratin-19 fragment (CYFRA 21.1) and interleukin 6 (IL-6), vascular endothelial growth factor (VEGF), soluble tumor necrosis factor receptor I (sTNF RI), and sTNF RII in patients with squamous cell carcinoma of the cervix. The subjects of analysis were 138 patients with stage I-IVA according to the International Federation of Gynecology and Obstetrics (FIGO) classification. The collected research material comes from one oncology center. During the 10 years of follow-up, 56 relapses and 53 deaths were observed, and recurrent disease in early stage was confirmed in 45 % of patients. The pretreatment serum levels of SCCAg and CYFRA 21.1, and cytokines IL-6, VEGF, sTNF RI, and sTNF RII were determined in all patients. The probability of disease-free survival (DFS) and overall survival (OS) was evaluated using the log-rank test and the Cox regression model. Based on the ROC curve analysis for patients with recurrence, the largest area under the curve was demonstrated for SCCAg and IL-6 and for patients who died, for SCCAg and VEGF. Cox analysis demonstrated that independent prognostic factor for DFS was only SCCAg and for OS cytokine IL-6 and SCCAg, but in patients with early stage the prognostic value for DFS was VEGF, whereas IL-6 and CYFRA 21.1 for OS. Serum level of VEGF, CYFRA 21.1 and IL-6 before treatment in patients with early stage cervical cancer appears to be an important prognostic factor.

Results of optimal debulking surgery with bowel resection in patients with advanced ovarian cancer.

BACKGROUND: The surgical treatment of patients with advanced-stage ovarian cancer is based on maximal cytoreduction with widening the debulking on the extra-ovarian tissues and infiltrated organs. The purpose of the study was to assess the outcome after optimal cytoreduction with partial bowel resection and to find the risk factors of relapse. Another goal was the quantitative and qualitative assessment of intra- and postoperative complications in the studied group. METHODS: The analysis of debulking procedures with intestinal resection and postoperative period in 33 ovarian cancer patients, The International Federation of Gynecology and Obstetrics (FIGO) stages III and IV, was performed. RESULTS: The optimal cytoreduction defined as less than 1.0 cm residual disease was achieved in all patients including the following: 26 patients (78.8%) with no macroscopic residual disease, 4 patients (12.1%) with the largest residual tumor less than 0.5, and 3 patients (9.1%) with 0.5 cm to less than 1.0 cm residual disease. The rectosigmoid resection was the most common surgical procedure (n = 27). The risk of relapse was significantly higher in subjects who had the macroscopic residual tumor left during the primary operation (57.1 vs. 11.5%, P = 0.035). A primary bowel tumor size was another predictor of relapse. The maximum tumor diameter was significantly larger (14.9 ± 6.7 cm vs. 10.3 ± 4.7 cm, P = 0.047) in patients who developed the relapse. CONCLUSIONS: As presented in the article, our outcomes and other authors' observations indicate that debulking surgery with bowel resection in patients with advanced ovarian cancer brings good results. Complications connected with bowel surgery are to be accepted. The interesting thing is that a primary bowel tumor size was a predictor of relapse.

[Acute urinary retention due to cervical myoma--a case report and a review of the literature]. / Ostre zatrzymanie odplywu moczu spowodowane miesniakiem szyjki macicy--opis przypadku i przeglad literatury.

CASE REPORT: A 48-year-old woman with acute urinary retention due to a big cervical leiomyoma pressing on the urethra was admitted to the Gynecologic Unit. A Foley catheterization was performed and 1500 mL of urine was drained. The gynecologic examination revealed a cervical tumor 10 cm in diameter. Acute urinary retention and intensifying abdominal pain were indications for emergency surgery. The presented case of obstructive urinary retention is a rare finding as the literature offers only single reports on the symptoms of cervical fibroids and the treatment methods. CONCLUSIONS: Cervical leiomyoma is a rare cause of acute urinary retention. The surgical procedure requires considerable experience to avoid intraoperative bleeding and bladder or bowel complications.

Uterine tumors resembling ovarian sex cord tumors, a clinicopathologic study of six cases.

Uterine tumors resembling ovarian sex cord tumors (UTROSCTs) cause difficulties, both with respect to diagnosis as well as to the nomenclature. They belong to the group of low-grade malignant neoplasms, and their clinical course likely depends on the percentage of the sex cord-like component. Morphologically, they can be divided into type I and type II with less or more than 50% of sex cord-like areas, respectively. Six patients with an age range of 24 to 63 years underwent the treatment for primary UTROSCT at the Cancer Center and Institute of Oncology in Warsaw, Poland, between 2000 and 2011. In addition to the surgery, 4 patients were treated with gestagens. Biopsies or excisions from the tumors were examined microscopically and immunohistochemically. Two cases were classified as type I, and 4 cases, as type II tumors. The tumor size ranged from 3 to 24 cm. The sex cord component varied from 25% to 70%. By immunohistochemical examination, the sex cord-like component was calretinin positive, whereas the stromal component was positive for CD10 and negative for h-caldesmon in all the cases studied. In addition, progesterone receptor positivity was found in all the cases, and 4 tumors were positive for smooth muscle actin, cytokeratin AE1/3, and inhibin. No recurrences were noted in any of the 6 patients over 3 to 14.5 years of follow-up period. A correct subclassification of sarcomas of UTROSCT type is of crucial importance because most patients with this rare neoplasm respond well to gestagen therapy and have a good prognosis, compared with other uterine stromal sarcomas.

Discrepancy between recommendations regarding hyperthermic intraperitoneal chemotherapy (HIPEC) in ovarian cancer management: a narrative review.

BACKGROUND AND OBJECTIVE: Hyperthermic intraperitoneal chemotherapy (HIPEC) is still controversial in ovarian cancer (OC) management. Doubts are related mainly to HIPEC effectiveness, but also to its safety. European Society of Medical Oncology and European Society of Gynecologic Oncology do not consider HIPEC as a standard of care. Opposite to European recommendations, National Comprehensive Cancer Network found HIPEC as a treatment option in patients undergoing interval debulking surgery in first-line treatment. This may be confusing for oncologists in clinical practice. The aim of this narrative review is to present literature review focusing on efficacy, confounding factors, complications and immunological issue of HIPEC in OC management. METHODS: PubMed was searched for meta-analyses, randomized trials, observational studies, experimental studies to outline the role of HIPEC in OC management since January 2015 until August 2023. Keywords included "hyperthermic intraperitoneal chemotherapy", "HIPEC", "ovarian cancer", "immune response". References from full-text articles were screened for additional studies. KEY CONTENT AND FINDINGS: Most meta-analyses found that HIPEC improved survival in patients with OC and none of the meta-analyses showed that addition HIPEC to surgery was associated with a worse treatment outcome compared to surgery alone. Positive effect on treatment outcome was found more common in first-line treatment than recurrent disease. Positive effect on treatment outcome was more common in first-line treatment (especially during interval debulking surgery) than recurrent disease. HIPEC efficacy can be affected by patients' characteristics (BRCA status, platinum sensitivity), cytostatic type and dose, intensity of hyperthermia and peritoneal flow characteristics. Apart from strict cytotoxic effect, HIPEC can induce anti-cancer immune response. CONCLUSIONS: Although factors confounding HIPEC efficacy are not well-defined, survival improvement, related to addition HIPEC to surgery in OC, was observed. Future studies should focus on determining a subgroup of patients, who benefit from HIPEC. This will contribute to the unification of European and American recommendations.

microRNAs in uterine sarcomas and mixed epithelial-mesenchymal uterine tumors: a preliminary report.

Uterine sarcomas and mixed epithelial-mesenchymal uterine tumors are a heterogeneous group of rare tumors for which there are very few diagnostic markers available. As aberrant microRNA (miRNA) expression patterns represent putative diagnostic cancer markers, we aimed to identify miRNA expression profiles of the major uterine sarcoma subtypes and mixed epithelial-mesenchymal tumors of the uterus. Eighty-eight miRNAs were assessed by quantitative RT-PCR in cancerous and non-cancerous tissue samples collected from 29 patients with endometrial sarcoma, leiomyosarcoma, and mixed epithelial-mesenchymal tumors. Tumor and control samples significantly (P < 0.05) differed in the expression of miR-23b, miR-1, let-7f, and let-7c in endometrial sarcomas, and miR-1, let-7c, miR-133b, let-7b, miR-143, let-7a, let-7d, let-7e, let-7g, miR-222, let-7i, and miR-214 in mixed epithelial-mesenchymal tumors. All the significantly changed miRNAs were down-regulated in the malignant tissues as compared to their normal counterparts. This may suggest their tumor suppressor role in these malignancies. No statistically significant changes in miRNA expression levels were found between leiomyosarcoma tumors and controls. The identified miRNAs warrant further studies as valuable candidate markers for the differential diagnosis of uterine sarcomas from benign uterine lesions and between uterine sarcoma subtypes.

Contraception for cancer survivors.

Modern methods of diagnosis and treatment allow for better survival outcomes and, more importantly, for higher curability of cancer. Female cancer survivors often need effective advice concerning the choice of birth control methods. The majority of gynecologists are reluctant to propose anything other than barrier methods due to lack of information concerning safe use of more effective contraceptives. The aim of the paper was to summarize indications and contraindications to different methods of contraception available to cancer survivors in Poland.

Reproductive Results in Cancer Survivors after Fertility Sparing Management: The Need for the Standardization of Definitions.

In fertility-sparing management (FSM), two different issues can be distinguished: the risk of recurrence/death and the chance of childbearing. Survival is the principal outcome in oncology, and definitions of overall survival and progression-free survival are therefore well defined and widely accepted. The introduction of FSM to clinical practice was determined by the desire of young cancer patients to still have children. Initially, in small groups of patients, any pregnancy and/or childbirth were considered successes. Nowadays, FSM occupies an important place in cancer treatment, with thousands of young women treated successfully. However, in contrast to survival, no definition has been established for evaluating the reproductive outcomes of FSM. This review article evaluates the current pregnancy and birth rates of cancer patients. Differences between fertility-sparing and conservative treatment are analyzed, and improper and confusing interchangeable applications of these terms are pointed out. Additionally, various reasons for choosing FSM as a treatment method-which are not directly related to fertility preservation (treatment mismatch)-are presented. Uniform definitions of reproduction after FSM should be established to enable the comparison of results and facilitate the counseling of patients regarding the chances of reproduction.

Obstetric Results after Fertility-Sparing Management of Non-Epithelial Ovarian Cancer.

PURPOSE: To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer. METHODS: The study included 146 patients with germ cell (GCT, n = 84) and sex cord-stromal tumors (SCST, n = 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I. RESULTS: The 5- and 10-year disease-free survival rates were 91% and 83%, respectively. The recurrence risk was not associated with tumor histology, stage or age. Twenty-four months after the treatment, the rate of recurrence was higher than the rate of childbearing. The childbearing rates kept rising after the treatment and exceeded the rate of recurrence after 2 years. The cumulative incidence rates of birth 36, 60 and 120 months after treatment were 13.24%, 20.75%, and 42.37%, respectively. Chemotherapy was not related to childbearing. The patients' age was related to the chance of childbearing. CONCLUSIONS: The prognoses of GCT and SCST are similar. Close follow-ups along with contraception should be offered to women during the first two years after treatment due to the increased risk of recurrence. After this period, relapses are rare and women can safely become pregnant.

Social marketing in gynecological cancers prevention after the COVID-19 pandemic.

OBJECTIVES: Assessment of the development and description of the characteristics of social marketing in Poland and the United States with regard to the prevention of gynecological cancers and achievements of these countries. MATERIAL AND METHODS: Collective case study based on an analysis of five social campaigns in Poland and five social campaigns in the United States that were focused the gynecological cancers prevention. RESULTS: In the United States, there are more materials available on social campaigns dedicated to the prevention of gynecological cancers, and there are more public organizations that are involved in health promotion activities than in Poland. As opposed to American campaigns, Polish social campaigns did not cover all types of gynecological cancer. The study revealed that Facebook is the most commonly used social media platform by the social campaign organizers. CONCLUSIONS: Social marketing tools still have not been fully implemented in the prevention of gynecological cancers either in Poland or in the United States. However, social marketing in the US seems to be more effective in gynecological cancers prevention than Poland.
