RESUMEN
This study intended to investigate if gynecological cancers compromise ovarian function and reduce the success of assisted reproduction techniques (ART). No clinical and molecular data together is available on this issue for gynecological or other organ cancers. Steroidogenic pathways and DNA damage response characteristics of the granulosa cells retrieved from the 39 gynecological cancer patients were analyzed together with their clinical ART characteristics in comparison to 31 control ART patients. Patients with gynecological malignancies were similar to the control IVF patients for the number of mature oocytes retrieved, fertilization rates and embryo development competency. Molecular analyses of the granulosa cells retrieved from these cancer patients did not detect any perturbations in gonadotropin receptor expression and response, sex steroid production, cholesterol utilization/storage and, DNA damage response pattern in comparison to control IVF patients without cancer. This study provides the first reassuring clinical and molecular combined data set that the presence of gynecological malignancy does not appear to have any detrimental effect on clinical IVF cycle characteristics and ovarian functioning at molecular level.

Malignant peritoneal mesothelioma (MPM) is an exceptionally rare tumor type. Although some somatic/germline genetic alterations including BAP1 loss have been identified in some cases, the molecular properties of MPMs are remained poorly understood. In recent years, anaplastic lymphoma kinase (ALK) gene rearrangement was revealed in a subset of (3.4%) MPMs. Low-grade serous carcinomas (LGSCs) are a rare subtype of ovarian carcinoma and have some morphologic and immunophenotypic overlapping features with MPMs and this may cause misdiagnosis in daily practice. Here, we report a case of 18-year-old women with STRN-ALK-rearranged MPM and no previous exposure to asbestos. This case was presented with bilateral pelvic masses and histologically was displaying pure papillary morphology with mild-to-moderate nuclear atypia, psammoma bodies, and diffuse PAX8 expression as LGSCs. With the detection of ALK alteration in some of the MPMs, a targeted treatment option has emerged for these unusual tumor types.

The aim of this study was to assess the impact of low-volume metastasis (LVM) on disease-free survival (DFS) in women with apparent early-stage endometrial cancer (EC) who underwent sentinel lymph node (SLN) mapping. Patients with pre-operative early-stage EC were retrospectively collected from an international collaboration including 13 referring institutions. A total of 1428 patients were included in this analysis. One hundred and eighty-six patients (13%) had lymph node involvement. Fifty-nine percent of positive SLN exhibited micrometastases, 26.9% micrometastases, and 14% isolated tumor cells. Seventeen patients with positive lymph nodes did not receive any adjuvant therapy. At a median follow-up of 33.3 months, the disease had recurred in 114 women (8%). Patients with micrometastases in the lymph nodes had a worse prognosis of disease-free survival compared to patients with negative nodes or LVM. The rate of recurrence was significantly higher for women with micrometastases than those with low-volume metastases (HR = 2.61; p = 0.01). The administration of adjuvant treatment in patients with LVM, without uterine risk factors, remains a matter of debate and requires further evaluation.
RESUMEN
STUDY QUESTION: Are the IVF parameters and the steroidogenic luteal characteristics of random-start IVF cycles different from conventional cycles in cancer patients? SUMMARY ANSWER: No; controlled ovarian stimulation cycles randomly started at late follicular phase (LFP) and luteal phase (LP) are totally comparable to those conventional IVF cycles started at early follicular phase (EFP) in terms of the expression of the enzymes involved in cholesterol utilization and steroid hormone biosynthesis pathways, gonadotropin receptor expression and, estradiol (E2) and progesterone (P4) production in addition to the similarities in ovarian response to gonadotropin stimulation, oocyte yield, fertilization rate and embryo development competency in cancer patients. WHAT IS KNOWN ALREADY: Random start ovarian stimulation protocols are commonly employed for oocyte and embryo freezing for fertility preservation in cancer patients with time constraints who do not have sufficient time to undergo ovarian stimulation initiated conventionally at EFP of the next cycle. No data is available regarding the molecular steroidogenic features of these cycles analyzed together with the clinical IVF characteristics in cancer patients. We aimed to address this question in this study to help understand how similar the random start cycles are to the conventional start ones. STUDY DESIGN, SIZE, DURATION: A clinical translational research study conducted in 62 cancer patients undergoing IVF for fertility preservation between the years 2017 and 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Sixty-two patients who were diagnosed with different types of cancer and underwent ovarian stimulation for oocyte (n = 41) and embryo (n = 21) cryopreservation using GnRH antagonist protocol and human menopausal gonadotropins before receiving cancer treatment/surgery were enrolled in the study. For patients with breast cancer and endometrial cancer the aromatase inhibitor letrozole was used with gonadotropin stimulation. Ovarian stimulation was initiated conventionally at EFP in 22 patients and served as control while it was started at LFP in 20, and mid-LP in the other 20 patients. The luteinized granulosa cells (GCs) were recovered from follicular aspirates during oocyte retrieval procedure and used for the experiments separately for each individual patient. The expression of the enzymes involved in sex steroid biosynthesis (StAR, 3ß-HSD, Aromatase) and cholesterol synthesis (3-hydroxy 3-methylglutaryl Co-A reductase (HMG-Co-A reductase)), utilization (hormone sensitive lipase (HSL)), and storage (Acetyl-Coenzyme A acetyltransferase 1 (ACAT-1)), and gonadotropin receptor expression status were analyzed using immunoblotting and RT-PCR methods. Laser confocal immunofluorescence imaging was applied to analyze and compare the expression patterns of the steroidogenic enzymes and their relation with mitochondria. In vitro E2 and P4 production by the cells were compared among the groups. MAIN RESULTS AND THE ROLE OF CHANCE: Baseline demographic and IVF characteristics of the patients undergoing the conventional start and random start IVF cycles were similar. Duration of gonadotropin stimulation was significantly longer in LFP and LP start cycles in comparison to the conventional ones. Ovarian response to gonadotropin stimulation, mature and total oocyte yield, fertilization and Day 5 blastulation rates of the embryos were comparable between the conventional versus random start cycles. When the luteal GCs of these random start cycles were analyzed we could not find any gross differences between these cycles in terms of the viability index and gross light microscopic morphologic features. More detailed analysis of the molecular luteal characteristics of the cells using RT-PCR, immunoblotting methods revealed that the expression profiles of the gonadotropin receptors, and the enzymes involved in sex steroid biosynthesis and cholesterol synthesis/utilization, and the steroidogenic activity of the luteal GCs of the random start cycles are almost identical to those of the conventional start cycles. Confocal image analysis demonstrated similar patterns in the signal expression profiles of the steroidogenic enzymes and their co-localization within mitochondria. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: Caution should be exercised when interpreting our data and counseling cancer patients seeking fertility preservation because it is still unclear if previous exposure to cancer drugs, different ovarian pathologies or infertility etiologies, previous ovarian surgery and/or any other underlying diseases that are concomitantly present with cancer may cause a difference between conventional and random start stimulation protocols in terms of IVF parameters, luteal function and reproductive outcome. Relatively low number of patients in each stimulation protocol and pooling of luteal GCs for each patient rather than individual analysis of each follicle and oocyte are additional limitations of our study. WIDER IMPLICATIONS OF THE FINDINGS: Our findings provide reassurance that random start protocol offers cancer patients an equally good prospect of fertility preservation as conventional IVF.

BACKGROUND: To evaluate gynecologic oncologists' trends and attitudes towards the use of Minimally invasive surgery (MIS) in active period of the COVID-19 pandemic in Turkey. METHODS: Online national survey sent to members of Turkish Endoscopy Platform consisting of six sections and 45 questions between the dates 1-15 June 2020 in Turkey to explore their surgical practice during the pandemic in three hospital types: Education and research hospital/university hospital, state hospital and private Hospital. Participants were gynecologic oncologists who are members of Turkish Endoscopy Platform. RESULTS: Fifty-eight percent of participants canceled all operations except for cancer surgeries and emergent operations. About a quarter of participants (28%) continued to operate laparoscopically and/or robotically. For the evaluation of the suspected adnexial mass (SAM) 64% used laparotomy and only 13 % operated by laparoscopy (L/S). For the management of low-risk early-stage endometrial cancer only fifth of the participants preferred to perform L/S. For endometrial cancer with high-intermediate risk factors more than half of participants preferred complete staging with laparotomy. For advanced stage ovarian cancer, one-fifth of the participants preferred to perform an explorative laparotomy, whilst 15 % preferred diagnostic laparoscopy to triage the patients for either NACT or cytoreductive surgery. On the contrary 41 % of participants chose to have cytology by paracentesis for neo-adjuvant chemotherapy (NACT). Gynecologic oncologists with >10 years L/S experience used MIS more for SAM. Furthermore, experienced surgeons used L/S more for endometrial cancer patients. In busy COVID hospitals, more participants preferred laparotomy over L/S. CONCLUSION: Use of MIS decreased during the pandemic in Turkey. More experienced surgeons continued to perform MIS. Surgical treatment was the preferred approach for SAM, early-stage endometrial cancer. However, NACT was more popular compared to radical surgery.

INTRODUCTION: This study aimed to evaluate the diagnostic accuracy of the sentinel lymph node (SLN) mapping algorithm in high-risk endometrial cancer patients. METHODS: Two hundred forty-four patients with non-endometrioid histology, grade 3 endometrioid tumors and/or tumors with deep myometrial invasion were enrolled in this retrospective, multicentric study. After removal of SLNs, all patients underwent pelvic ± paraaortic lymphadenectomy. Operations were performed via laparotomy, laparoscopy or robotic surgery. Indocyanine green (ICG) and methylene blue (MB) were used as tracers. SLN detection rate, sensitivity, negative predictive value (NPV) and false-negative rate (FNR) were calculated. RESULTS: Surgeries were performed via laparotomy in 132 (54.1%) patients and 152 (62.3%) underwent both bilateral pelvic and paraaortic lymphadenectomy. At least 1 SLN was detected in 222 (91%) patients. Fifty-five (22.5%) patients had lymphatic metastasis and 45 patients had at least 1 metastatic SLN. Lymphatic metastases were detected by side-specific lymphadenectomy in 8 patients and 2 patients had isolated paraaortic metastasis. Overall sensitivity, NPV and FNR of SLN biopsy were 81.8%, 95% and 18.2%, respectively. By applying SLN algorithm steps, sensitivity and NPV improved to 96.4% and 98.9%, respectively. For grade 3 tumors, sensitivity, NPV and FNR of the SLN algorithm were 97.1%, 98.9% and 2.9%. CONCLUSION: SLN algorithm had high diagnostic accuracy in high-risk endometrial cancer. All pelvic metastases were detected by the SLN algorithm and the isolated paraaortic metastasis rate was ignorable. But long-term survival studies are necessary before this approach becomes standard of care.

Endocervical adenocarcinomas (ECAs) have been recently reclassified according to their morphologic features linked to etiology by the International Endocervical Adenocarcinoma Criteria and Classification (IECC) and this system is adopted by WHO 2020. This classification separates the ECAs as human papillomavirus (HPV)-associated (HPVA) and HPV-independent (HPVI) subtypes. According to WHO 2020, high risk (HR)-HPV association can be histologically recognized by the presence of luminal mitoses and apoptosis. Therefore, investigating the reproducibility of the morphologic criteria of this new classification will be important in observing the recognizability of tumor types. Full slide sets of 94 ECAs were collected from 4 institutions in Turkey and reclassified on the basis of IECC/WHO 2020 criteria and the presence or absence of HR-HPV. HR-HPV presence was confirmed by HPV DNA in situ hybridization, p16 immunohistochemistry and in conflicted cases with real time-polymerase chain reaction. The final diagnoses were given based on the combination of the histologic evaluation and ancillary test results. Our cohort consisted of 73.4% HPVA and 26.6% HPVI cases. According to the WHO 2020 criteria 92.7% of HPVAs and 88% of HPVIs were easily classified. HPV DNA in situ hybridization was positive in 91.3% of the HPVAs and p16 was positive in all HPVAs, and also positive in 8% of the HPVIs. In conclusion, most of the ECAs can be diagnosed by their characteristic morphologic features by the WHO 2020 criteria. However, we want to emphasize that mitosis/apoptosis criteria may not be helpful especially in mucinous ECAs and ancillary tests for HR-HPV should be used in challenging cases.

Our goal was to address the safety of major gynaecologic cancer surgery without routine preoperative COVID-19 testing in the COVID-19 era. The databases of seven gynaecologic cancer centres were searched in order to identify all consecutive gynaecologic cancer patients undergoing major surgery between March 11, 2020 and May 15, 2020 for this retrospective, case-control study. The case group consisted of patients with histopathologically confirmed gynaecologic cancers, and each case was matched with two counterparts who had undergone primary surgery before the COVID-19 pandemic. The case and the control groups were compared in terms of length of hospital stay, admission to the intensive care unit (ICU), intraoperative and postoperative complications.During the study period, 154 women with gynaecologic cancer undergoing major surgery were identified. Although the case group had more co-morbidities compared to the control group (103/154 vs. 178/308, respectively; p = .04), the median length of hospital stays, the rate of ICU admission, intraoperative complication rates and postoperative complication rates were similar in the two groups. Gynaecologic cancer surgery may be performed safely in the COVID-19 era with similar rates of ICU admission, intraoperative and postoperative complications compared to the patients operated before the COVID-19 pandemic.IMPACT STATEMENTWhat is already known on this subject? Many societies have announced their guidelines about the surgical management of gynaecologic cancer patients during the COVID-19 pandemic. However, most of them are not evidence-based and mostly on expert opinions.What do the results of this study add? The main findings of this retrospective, case-control study indicate that the short-term (30 day) outcomes of gynaecologic cancer patients undergoing major surgery in the COVID-19 era are similar to those who had been operated before the COVID-19 pandemic. The length of hospital stays, the rates of admission to the ICU, intraoperative and postoperative complications were comparable between women undergoing major gynaecologic cancer surgery in the COVID-19 era and the women who had been operated before the pandemic.What are the implications of these findings for clinical practice and/or further research? We can suggest that definitive surgery may be performed for gynaecologic cancer patients in the COVID-19 era if the resources permit and appropriate precautions such as social distancing, isolation and the use of personal protective equipment are taken.

INTRODUCTION: We aimed to analyze the preliminary experience of a mini-plus percutaneous instrument (MpPc) setting in total laparoscopic hysterectomy (TLH). MATERIAL AND METHODS: Forty-three women who underwent a mini-plus percutaneous total laparoscopic hysterectomy at a tertiary-care university-based teaching hospital and academic affiliated private hospital between May 2017 and 2018 were included. MpPc-TLH was performed through one optical trans-umbilical 5-mm trocar, one 5-mm ancillary port on the right side, either one 2.4-mm percutaneous endoscopic instrument or 3-mm mini-laparoscopic port on the right upper quadrant and if required one 3-mm ancillary port on the left lower quadrant. RESULTS: A total of 43 patients were included, with a median age of 48 years (range, 38-71 years). Indication for surgery included uterine myomas (n = 20), benign adnexal mass (n = 7), endometrial intraepithelial neoplasia (n = 6), endometrial cancer (n = 5), adenomyosis with abnormal bleeding (n = 3), and high-grade cervical dysplasia (n = 2). The median operating time was 100 min (range, 60-180 min), and the median estimated blood loss was 30 ml (range, 20-60ml). The median postoperative abdominal pain Visual Analog Scale score was 3 (range, 0-6). CONCLUSIONS: The preliminary data suggest that MpPc approach is a feasible and safe surgical modality for total laparoscopic hysterectomy.

OBJECTIVE: This study evaluated diagnostic accuracy of intraoperative sentinel lymph node (SLN) frozen section examination and scrape cytology as a possible solution for management of SLN positive patients. STUDY DESIGN: Clinically early-stage endometrial cancer patients who underwent SLN algorithm and intraoperative SLN examination were analyzed. Findings were compared with final pathology results and diagnostic accuracy of frozen section and scrape cytology were evaluated. RESULTS: Of the 208 eligible patients, 100 patients (48 %) had frozen section examination and 108 (52 %) had scrape cytology of the SLN. Intraoperative examination and final pathology were negative for metastasis in 187/208 (90 %) cases. The rest 21 cases had metastatic SLNs according to final pathology. 12 of 21 (57 %) metastases were classified as macrometastasis. Intraoperative examination of SLNs correctly identified 13 cases (true positive) and missed 8 cases (false negative). Five of 8 false negative cases had micrometastasis or isolated tumor cells. Considering identification of macrometastasis, sensitivity and negative predictive value were 85.71 % and 98.94 %, respectively, for the frozen section and 60.00 % and 98.15 %, respectively, for the scrape cytology. CONCLUSION: Frozen section examination of SLN has higher sensitivity in detecting macrometastasis compared to scrape cytology and it could help the surgeon in decision for further lymphadenectomy intraoperatively.

OBJECTIVE: This study aims to evaluate the effect of the COVID-19 pandemic and related restrictions on patients who underwent cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) for ovarian cancer. METHODS: We retrospectively evaluated ovarian cancer patients who underwent HIPEC following complete cytoreductive surgery performed during the outbreak of the COVID-19 pandemic in three different centers specializing in gynecological oncology. All patients who underwent cytoreduction plus HIPEC for a primary, interval, and recurrent surgery were evaluated. Primary outcomes was postoperative 30-day morbidity and mortality. The secondary outcome was infection of patient and/or related staff with COVID-19 during the perioperative or early postoperative period. RESULTS: We performed a total of 35 HIPEC procedures during the pandemic: 15 (42.9%) patients underwent primary/interval surgery, while 20 (57.1%) patients had recurrent disease. Grade 3-4 complications occurred in one patient (2.9%) (chronic renal failure), while mortality did not occur in any patient. Neither the patients nor related staff were infected with the coronavirus during the perioperative or early postoperative period. One patient, who was diagnosed with COVID-19 pneumonia on postoperative day 80 died from the infection. Another patient died on postoperative day 85 due to progressive ovarian cancer, a disorder in vital functions, and organ failure. CONCLUSION: HIPEC during the COVID-19 pandemic seems a safe and feasible procedure, with acceptable morbidity and mortality rates. Careful selection of patients is important and precautions should be taken before the procedure.

BACKGROUND AND OBJECTIVES: The aim of this study was to analyze the factors affecting recurrence-free (RFS) and overall survival (OS) rates of women diagnosed with low-grade serous ovarian cancer (LGSOC). METHODS: Databases from 13 participating centers in Turkey were searched retrospectively for women who had been treated for stage I-IV LGSOC between 1997 and 2018. RESULTS: Overall 191 eligible women were included. The median age at diagnosis was 49 years (range, 21-84 years). One hundred seventy-five (92%) patients underwent primary cytoreductive surgery. Complete and optimal cytoreduction was achieved in 148 (77.5%) and 33 (17.3%) patients, respectively. The median follow-up period was 44 months (range, 2-208 months). Multivariate analysis showed the presence of endometriosis (p = .012), lymphovascular space invasion (LVSI) (p = .022), any residual disease (p = .023), and the International Federation of Gynecology and Obstetrics (FIGO) stage II-IV disease (p = .045) were negatively correlated with RFS while the only presence of residual disease (p = .002) and FIGO stage II-IV disease (p = .003) significantly decreased OS. CONCLUSIONS: The maximal surgical effort is warranted for complete cytoreduction as achieving no residual disease is the single most important variable affecting the survival of patients with LGSOC. The prognostic role of LVSI and endometriosis should be evaluated by further studies as both of these parameters significantly affected RFS.

BACKGROUND: We aimed to assess the feasibility and short-term clinical outcomes of surgical procedures for cancer at an institution using a coronavirus disease 2019 (COVID-19)-free surgical pathway during the peak phase of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. MATERIALS AND METHODS: This was a single-center study, including cancer patients from all surgical departments, who underwent elective surgical procedures during the first peak phase between March 10 and June 30, 2020. The primary outcomes were the rate of postoperative SARS-CoV-2 infection and 30-day pulmonary or non-pulmonary related morbidity and mortality associated with SARS-CoV-2 disease. RESULTS: Four hundred and four cancer patients fulfilling inclusion criteria were analyzed. The rate of patients who underwent open and minimally invasive procedures was 61.9% and 38.1%, respectively. Only one (0.2%) patient died during the study period due to postoperative SARS-CoV2 infection because of acute respiratory distress syndrome. The overall non-SARS-CoV2 related 30-day morbidity and mortality rates were 19.3% and 1.7%, respectively; whereas the overall SARS-CoV2 related 30-day morbidity and mortality rates were 0.2% and 0.2%, respectively. CONCLUSIONS: Under strict institutional policies and measures to establish a COVID-19-free surgical pathway, elective and emergency cancer operations can be performed with acceptable perioperative and postoperative morbidity and mortality.

Fertility-sparing surgery has gained popularity in the last three decades for the management of cervical cancer in women under 40 years of age. Radical trachelectomy is a fertility-sparing surgical technique for women who wish to retain their fertility. Vaginal-assisted laparoscopic radical trachelectomy is feasible in selected patients with early cervical cancer. The aim of this video is to present a nerve-sparing vaginal-assisted laparoscopic radical trachelectomy demonstrating pelvic anatomical structures.
RESUMEN
BACKGROUND: Primary retroperitoneal Müllerian adenocarcinoma (PRMA) is a very rare type of primary retroperitoneal tumour. CASE 1: A 45-year-old woman presented with left lower extremity swelling and pain. Imaging revealed that the tumour had invaded the left common iliac vein and artery, internal and external iliac arteries, sciatic and obturator nerves, and pelvic wall. CASE 2: A 37-year-old was admitted with pelvic pain. Imaging showed the tumor at the left iliac bifurcation infiltrating the internal iliac artery and left sciatic, obturator, and femoral nerves. Both of these patients were treated with radical surgery that achieved no visible tumour at the end of the operation. CONCLUSION: There is no guideline for the diagnosis and management of this entity due to its rarity. These cases should be managed at highly specialized centres with expertise in radical surgery.

BACKGROUND AND OBJECTIVES: The purpose of this study was to find out the risk factors associated with non-sentinel lymph node metastasis and determine the incidence of non-sentinel lymph node metastasis according to risk groups in sentinel lymph node (SLN)-positive endometrial cancer patients. METHODS: Patients who underwent at least bilateral pelvic lymphadenectomy after SLN mapping were retrospectively analyzed. Patients were categorized into low, intermediate, high-intermediate, and high-risk groups defined by ESMO-ESGO-ESTRO. RESULTS: Out of 395 eligible patients, 42 patients had SLN metastasis and 16 (38.1%) of them also had non-SLN metastasis. Size of SLN metastasis was the only factor associated with non-SLN metastasis (p = .012) as 13/22 patients with macrometastasis, 2/10 with micrometastasis and 1/10 with isolated tumor cells (ITCs) had non-SLN metastasis. Although all 4 metastases (1.8%) among the low-risk group were limited to SLNs, the non-SLN involvement rate in the high-risk group was 42.9% and all of these were seen in patients with macrometastatic SLNs. CONCLUSIONS: Non-SLN metastasis was more frequent in higher-risk groups and the risk of non-SLN metastasis increased with the size of SLN metastasis. Proceeding to complete lymphadenectomy when SLN is metastatic should further be studied as the effect of leaving metastatic non-SLNs in-situ is not known.

OBJECTIVE: We aimed to investigate if there is a correlation between in-vitro AMH production and primordial follicle reserve of the ovarian cortical samples in culture. METHODS: Seven patients undergoing laparoscopic excision of ovarian dermoid cysts were included in the study. 0.5 × 0.5 cm of ovarian cortical samples embedded within the cyst wall were removed and cultured for one day. Then, the cultured cortical pieces were fixed, paraffin-embedded and serially sectioned for histormorphometric analysis. AMH and estradiol (E2) production of the samples after one-day culture period were measured in the spent culture media. Primordial follicle density was expressed as the number of primordial follicles per mm2. Pearson correlation and linear regression analyses were applied. RESULTS: The mean age of the patients was 29.2 ± 6.8 (ranging from 18 to 36). There was a negative correlation between age and PF density (r=-0.92, %95CI: -0.99 to -0.76, p < 0.001). In-vitro AMH level of the cortical samples was significantly associated with age (R2 = 0.67, p = 0.023), primordial follicle density (R2 = 0.71, p = 0.015). There was a borderline significance between in-vitro levels of AMH and E2 level (R2 = 0.55, p = 0.058). A similar comparison could not be made for secondary follicles (preantral and small antral follicles) because of their rarity in the histological sections analyzed. CONCLUSIONS: This histomorphometric study provides evidence that in-vitro AMH production of the ovarian cortical samples reflects primordial follicle pool of the samples.
