Enterobius vermicularis usually causes trivial infections in the juvenile population. However, its extragenital presentation in adults is relatively rare. We present the case of a 64-year-old female suffering from poorly controlled diabetes and lower abdominal pain. CT scan showed a large tumorous expansion of the lower abdomen, mimicking malignancy. Perioperative findings revealed a large adnexal tumor adhering to the rectum. In addition, the histological examination uncovered a mixed inflammatory infiltrate with multiple surrounding eggs of the parasite and granulomatous reaction in the left fallopian tube and left ovarian cortex. As reported in our article, the rare ectopic sites of Enterobius vermicularis in postmenopause may become a diagnostic challenge.

OBJECTIVES: To compare the performance of transvaginal and transabdominal ultrasound with that of the first-line staging method (contrast-enhanced computed tomography (CT)) and a novel technique, whole-body magnetic resonance imaging with diffusion-weighted sequence (WB-DWI/MRI), in the assessment of peritoneal involvement (carcinomatosis), lymph-node staging and prediction of non-resectability in patients with suspected ovarian cancer. METHODS: Between March 2016 and October 2017, all consecutive patients with suspicion of ovarian cancer and surgery planned at a gynecological oncology center underwent preoperative staging and prediction of non-resectability with ultrasound, CT and WB-DWI/MRI. The evaluation followed a single, predefined protocol, assessing peritoneal spread at 19 sites and lymph-node metastasis at eight sites. The prediction of non-resectability was based on abdominal markers. Findings were compared to the reference standard (surgical findings and outcome and histopathological evaluation). RESULTS: Sixty-seven patients with confirmed ovarian cancer were analyzed. Among them, 51 (76%) had advanced-stage and 16 (24%) had early-stage ovarian cancer. Diagnostic laparoscopy only was performed in 16% (11/67) of the cases and laparotomy in 84% (56/67), with no residual disease at the end of surgery in 68% (38/56), residual disease ≤ 1 cm in 16% (9/56) and residual disease > 1 cm in 16% (9/56). Ultrasound and WB-DWI/MRI performed better than did CT in the assessment of overall peritoneal carcinomatosis (area under the receiver-operating-characteristics curve (AUC), 0.87, 0.86 and 0.77, respectively). Ultrasound was not inferior to CT (P = 0.002). For assessment of retroperitoneal lymph-node staging (AUC, 0.72-0.76) and prediction of non-resectability in the abdomen (AUC, 0.74-0.80), all three methods performed similarly. In general, ultrasound had higher or identical specificity to WB-DWI/MRI and CT at each of the 19 peritoneal sites evaluated, but lower or equal sensitivity in the abdomen. Compared with WB-DWI/MRI and CT, transvaginal ultrasound had higher accuracy (94% vs 91% and 85%, respectively) and sensitivity (94% vs 91% and 89%, respectively) in the detection of carcinomatosis in the pelvis. Better accuracy and sensitivity of ultrasound (93% and 100%) than WB-DWI/MRI (83% and 75%) and CT (84% and 88%) in the evaluation of deep rectosigmoid wall infiltration, in particular, supports the potential role of ultrasound in planning rectosigmoid resection. In contrast, for the bowel serosal and mesenterial assessment, abdominal ultrasound had the lowest accuracy (70%, 78% and 79%, respectively) and sensitivity (42%, 65% and 65%, respectively). CONCLUSIONS: This is the first prospective study to document that, in experienced hands, ultrasound may be an alternative to WB-DWI/MRI and CT in ovarian cancer staging, including peritoneal and lymph-node evaluation and prediction of non-resectability based on abdominal markers of non-resectability. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

OBJECTIVES: The aim of this study was to assess the detection rate, false-negative rate and sensitivity of SLN in LN staging in tumors over 2cm on a large cohort of patients. METHODS: Data from patients with stages pT1a - pT2 cervical cancer who underwent surgical treatment, including SLN biopsy followed by systematic pelvic lymphadenectomy, were retrospectively analyzed. A combined technique with blue dye and radiocolloid was modified in larger tumors to inject the tracer into the residual cervical stroma. RESULTS: The study included 350 patients with stages pT1a - pT2. Macrometastases, micrometastases, and isolated tumor cells were found in 10%, 8%, and 4% of cases. Bilateral detection rate was similar in subgroups with tumors<2cm, 2-3.9cm, and ≥4cm (79%, 83%, 76%) (P=0.460). There were only two cases with false-negative SLN ultrastaging for pelvic LN status among those with bilateral SLN detection. The false negative rate was very low in all three subgroups of different tumor sizes (0.9%, 0.9%, and 0.0%; P=0.999). Sensitivity reached 96% in the whole group and was high in all three groups (93%, 93%, 100%; P=0.510). CONCLUSIONS: If the tracer application technique is adjusted in larger tumors, SLN biopsy can be equally reliable in pelvic LN staging in tumors smaller and larger than 2cm. The bilateral detection rate and false negative rate did not differ in subgroups of patients with tumors<2cm, 2-3.9cm, and ≥4cm.

OBJECTIVE: To analyze the accuracy of ultrasound in assessing pelvic and intra-abdominal spread in patients with ovarian cancer. METHODS: This prospective study enrolled all consecutive patients referred to a single gynecological oncology center for suspected ovarian cancer. We analyzed only data from patients with histologically confirmed primary ovarian cancer who were evaluated following predefined preoperative ultrasound, intraoperative and pathology protocols. We evaluated the agreement of depth of infiltration of the rectosigmoid wall, tumor spread in different peritoneal compartments and presence of metastatic retroperitoneal and inguinal lymph nodes, as determined at ultrasound, with intraoperative and histopathological findings. RESULTS: In total, 578 patients were enrolled between March 2008 and January 2013, of whom 394 met the study inclusion criteria and were analyzed; 74% of these suffered from advanced-stage cancer. Our results showed excellent agreement between ultrasound and histology in assessment of rectosigmoid wall infiltration (kappa value, 0.812; area under the receiver-operating characteristics curve, 0.898). The overall accuracy in evaluating different peritoneal compartments, retroperitoneal and inguinal lymph nodes and depth of rectosigmoid wall infiltration was 85.3%, 84.8%, 99.7% and 91.1%, respectively. Ultrasound showed high sensitivity only in the assessment of rectosigmoid wall infiltration (83.1%), peritoneal spread into the pelvis (81.4%) and omentum (67.3%), and inguinal metastatic lymph nodes (100%). The specificity of ultrasound in detection of all evaluated parameters was > 90%. CONCLUSION: This is the largest imaging study to date on ovarian cancer staging. Ultrasound can be used as the method of choice to plan rectosigmoid wall resection and dissection of infiltrated inguinal lymph nodes. In assessing different peritoneal and retroperitoneal compartments, ultrasound was accurate and highly specific. However, similar to other modern imaging techniques, it had relatively low sensitivity, further supporting the role of comprehensive surgical staging. Copyright © 2016 ISUOG.

OBJECTIVE: To examine prospectively the accuracy of ultrasound in predicting rectosigmoid tumor infiltration in patients with epithelial ovarian cancer. METHODS: Patients referred for a suspicious pelvic mass between 2012 and 2014 were examined by ultrasound following the standard protocol for assessment of tumor infiltration. Of the 245 patients examined, 191 had proven ovarian cancer and underwent primary surgery and were included in the analysis. Patients with apparently benign or inoperable disease were excluded. Rectosigmoid infiltration was evaluated by histopathology or according to perioperative findings. Clinical, pathological and laboratory parameters were analyzed as factors potentially affecting the sensitivity and specificity of sonography. RESULTS: The sensitivity of ultrasound in detecting rectosigmoid infiltration in patients with ovarian cancer was 86.3%, with specificity of 95.8%, positive predictive value of 92.6%, negative predictive value of 91.9% and overall accuracy of 92.1%. CONCLUSION: Ultrasound is a highly accurate method for detecting rectosigmoid tumor infiltration in ovarian cancer patients, and thus, can be used for planning adequate management, including patient consultation, surgical team planning, suitable operating time and postoperative care.

OBJECTIVE: To describe the technique and report experiences with pelvic floor reconstruction by modified rectus abdominis myoperitoneal (MRAM) flap after extensive pelvic procedures. METHODS: Surgical technique of MRAM harvest and transposition is carefully described. The patients in whom pelvic floor reconstruction with MRAM after either infralevator pelvic exenteration and/or extended lateral pelvic sidewall excision was carried out were enrolled into the study (MRAM group, n=16). Surgical data, post-operative morbidity, and disease status were retrospectively assessed. The results were compared with a historical cohort of patients, in whom an exenterative procedure without pelvic floor reconstruction was performed at the same institution (control group, n=24). RESULTS: Both groups were balanced in age, BMI, tumor types, and previous treatment. Substantially less patients from the MRAM group required reoperation within 60days of the surgery (25% vs. 50%) which was due to much lower rate of complications potentially related to empty pelvis syndrome (1 vs. 7 reoperations) (p=0.114). Late post-operative complication rate was substantially lower in the MRAM group (any grade: 79% vs. 44%; grade≥3: 37% vs. 6%) (p=0.041). The performance status 6months after the surgery was ≤1 in the majority of patients in MRAM (81%) while in only 38% of patients from the control group (p=0.027). There was one incisional hernia in MRAM group while three cases were reported in the controls. CONCLUSIONS: Pelvic floor reconstruction by MRAM in patients after pelvic exenterative procedures is associated with a substantial decrease in postoperative complications that are potentially related to empty pelvis syndrome.

OBJECTIVE: A high sensitivity of sentinel lymph nodes (SLN) for pelvic lymph node (LN) staging has been repeatedly shown in patients with cervical cancer. However, since only SLN are evaluated by pathologic ultrastaging, the risk of small metastases, including small macrometastases (MAC) and micrometastases (MIC), in non-SLN is unknown. This can be a critical limitation for the oncological safety of abandoning a pelvic lymphadenectomy. METHODS: The patients selected for the study had cervical cancer and were at high risk for LN positivity (stage IB-IIA, biggest diameter≥3cm). The patients had no enlarged or suspicious LN on pre-operative imaging; SLNs were detected bilaterally and were negative on intra-operative pathologic evaluation. All SLNs and all other pelvic LNs were examined using an ultrastaging protocol and processed completely in intervals of 150μm. RESULTS: In all, 17 patients were enrolled into the study. The mean number of removed pelvic LNs was 30. A total of 573 pelvic LNs were examined through ultrastaging protocol (5762 slides). Metastatic involvement was detected in SLNs of 8 patients (1× MAC; 4× MIC; 3× ITC) and in non-SLNs in 2 patients (2× MIC). In both cases with positive pelvic non-SLNs, there were found MIC in ipsilateral SLNs. No metastasis in pelvic non-SLNs was found by pathologic ultrastaging in any of the patients with negative SLN Side-specific sensitivity was 100% for MAC and MIC. There was one case of ITC detected in non-SLN, negative ipsilateral SLN, but MIC in SLN on the other pelvic side. CONCLUSIONS: After processing all pelvic LNs by pathologic ultrastaging, there were found no false-negative cases of positive non-SLN (MAC or MIC) and negative SLN. SLN ultrastaging reached 100% sensitivity for the presence of both MAC and MIC in pelvic LNs.
OBJECTIVE: Evaluate prognostic significance of low volume disease detected in sentinel nodes (SN) of patients with early stages cervical cancer. Although pathologic ultrastaging of SN allows for identification of low volume disease, including micro-metastasis and isolated tumor cells (ITC), in up to 15% of cases, prognostic significance of these findings is unknown. METHODS: A total of 645 records from 8 centers were retrospectively reviewed. Enrolled in our study were patients with early-stage cervical cancer who had undergone surgical treatment including SN biopsy followed by pelvic lymphadenectomy and pathologic ultrastaging of SN. RESULTS: Macrometastasis, micrometastasis, and ITC were detected by SN ultrastaging in 14.7%, 10.1%, and 4.5% patients respectively. False negativity of SN ultrastaging reached 2.8%. The presence of ITC was not associated with significant risk, both for recurrence free survival and overall survival. Overall survival was significantly reduced in patients with macrometastasis and micrometastasis; hazard ratio for overall survival reached 6.85 (95% CI, 2.59-18.05) and 6.86 (95% CI, 2.09-22.61) respectively. Presence of micrometastasis was an independent prognostic factor for overall survival in a multivariable model. CONCLUSION: Presence of micrometastasis in SN in patients with early stage cervical cancer was associated with significant reduction of overall survival, which was equivalent to patients with macrometastasis. No prognostic significance was found for ITC. These data highlight the importance of SN biopsy and pathologic ultrastaging for the management of cervical cancer.

OBJECTIVES: The incidence of cervical cancers increases with age. Due to the trend of increasing age of first pregnancy, abnormal Pap smears including those classified as atypical glandular cells (AGC) are being found more often in early pregnancy. Once invasive cancer is excluded, conservative management of squamous intraepithelial lesions (SIL) in pregnancy is considered safe; however, optimal management of AGC is not well established. The aim of our study was to evaluate the outcome of patients with AGC diagnosed from smears during pregnancy. METHODS: The study included 17 patients referred to us in early pregnancy with Pap smears reported as AGC: 11 not otherwise specified (AGC-NOS), five favour neoplasia (AGC-FN) and one adenocarcinoma in situ (AIS). Thirty-one with high-grade SIL (HSIL) Pap smears confirmed on punch biopsy in early pregnancy comprised a control group. Human papillomavirus (HPV) positivity was found in seven patients with persistent AGC-NOS (including all four who had CIN3 postpartum). All the women were initially examined by expert colposcopy and those with AGC-FN or AIS smears also by transrectal ultrasound to exclude invasive endocervical cancer. Follow-up controls were carried out every 8-12 weeks and, if there were no signs of progression, revaluation was scheduled 6-8 weeks after delivery. RESULTS: The mean age of the women was 31.4 years. Conization in one patient in the study group was performed in the 16th week of pregnancy due to colposcopic signs of microinvasive squamous cell cancer confirmed on histology. Progression to invasive cancer was not found in any of the other 16 patients in the study group or in the control group. Cervical intraepithelial neoplasia or AIS was confirmed postpartum by conization or punch biopsy in 47.1% (8/17) of patients in the study group and, in 77.4% (24/31) of patients in the control group. CONCLUSIONS: Conservative management of women with AGC in pregnancy is safe where invasive cancer is excluded. As histological verification of glandular pre-cancerous lesions by punch biopsy is not reliable and the postpartum regression rate cannot be determined precisely, conization should be performed in all cases with AGC-FN or AIS. Triage of persistent AGC-NOS with HPV testing is useful in distinguishing significant underlying lesions.

Cíl studie: Srovnání peroperační a pooperační morbidity u pacientek radikálně operovaných pro karcinom děložního hrdla po podání neoadjuvantní chemoterapie a pro primárně malý nádor děložního hrdla. Typ studie: Retrospektivní case-control studie. Název a sídlo pracoviště: Gynekologicko-porodnická klinika 1. LF UK a VFN, Praha. Metodika: Do studie bylo zařazeno 24 pacientek s dlaždicobuněčným karcinomem děložního hrdla, u nichž byla od 1/2004 do 6/2006 provedena radikální hysterektomie se systematickou pánevní lymfadenektomií po předchozím podání neoadjuvantní chemoterapie (NACT). Kontrolní skupina 24 pacientek byla vybrána retrospektivně ze souboru radikálně operovaných žen ve stejném období, avšak pro primárně malý nádor děložního hrdla stadia IA2 či IB1. Kritériem pro výběr kontrolní skupiny byla velikost nádoru odpovídající zmenšenému nádoru po aplikaci NACT. V obou souborech byly sledovány následující parametry – operační čas, krevní ztráta objektivizovaná rozdílem hodnot předoperačního a pooperačního hemoglobinu a hematokritu, nutnost podání krevní transfuze, peroperační komplikace, časné pooperační komplikace (do 6 týdnů po operaci), doba hospitalizace a ponechání zavedené epicystostomie pro hypotonický močový měchýř do domácí péče. Výsledky: U 92 % pacientek bylo po NACT dosaženo klinické odpovědi, která umožnila provedení radikální operace. Po NACT byl objem původního nádoru zmenšen průměrně o 70 % (58–100 %). Mezi skupinou pacientek léčených NACT s následnou radikální hysterektomií a kontrolní skupinou radikálně operovaných pro primárně malý nádor děložního hrdla nebyl významný rozdíl v operačním čase (165 min. vs. 160 min.), krevní ztrátě (rozdíl předoperačních a pooperačních hodnot hemoglobinu 18 g/l vs. 19 g/l, rozdíl předoperačních a pooperačních hodnot hematokritu 0,056 vs. 0,064), podání krevní transfuze (25 % vs. 21 %) a délce hospitalizace (9,5 dne vs. 9,6 dne). Významný rozdíl byl pouze v potřebě ponechání zavedené punkční epicystostomie do domácí péče (67 % vs. 47 %). Závěr: V hodnocených parametrech peroperační a pooperační morbidity u pacientek po NACT a u pacientek v kontrolním souboru nebyly významné rozdíly. Výjimkou je pouze potřeba delšího ponechání umělé derivace moči u pacientek po NACT podmíněná větší radikalitou výkonu na parametriích. Podání NACT v režimu ifosfamid / cisplatina (IP) zlepšilo operační podmínky u bulky dlaždicobuněčných karcinomů děložního hrdla.
Objective: To compare per-operative and post-operative morbidity in patients undergoing radical surgery for carcinoma of the uterine cervix after administration of a neoadjuvant chemotherapy, and for primarily small cervical tumour. Type of the study: A retrospective case-control study. Setting: Department of Obstetrics and Gyneacology, 1st Faculty of Medicine, Charles University and General Teaching Hospital, Prague. Methods: The study included 24 patients with squamous cell carcinoma of the uterine cervix who underwent radical hysterectomy including systematic pelvic lymphadenectomy after previous administration of neoadjuvant chemotherapy (NACT) during the period between 1/2004 and 6/2006. The control group of 24 patients was selected retrospectively from the population of women after radical surgery carried out in the same period, nevertheless, the controls underwent the surgery for primarily small carcinoma of the uterine cervix, stages IA2 or IB1. The tumour size consistent with the reduced tumour after NACT administration was the criterion for selection of the control group. The following parameters were monitored in both groups – duration of the surgery, blood loss objectivised by a difference in pre-operative and post-operative haemoglobin and haematocrit values, the need of blood transfusion, per-operative complications, early post-operative complications (up to 6 weeks after the surgery), duration of hospitalization and retaining the inserted epicystotostomy due to hypotonic bladder after discharge. Results: A therapeutic response allowing the radical surgery was achieved in 92% patients after NACT. After NACT the original tumour volume was reduced by 70% on the average (58% – 100%). No significant differences between the group of patients treated with NACT and undergoing subsequent radical hysterectomy and the control group were reported in terms of duration of the surgery (165 min. vs. 160 min.), blood loss (the difference in pre-operative and post-operative haemoglobin values 18 g/l vs. 19 g/l, the difference in pre-operative and post-operative haematocrit values 0.056 vs. 0.064), administration of blood transfusion (25% vs. 21%) and duration of hospitalization (9.5 days vs. 9.6 days). A significant difference was reported only in the need to retain the inserted epi-cystostomy after discharge (67% vs. 47%). Conclusion: There were no significant differences in the evaluated parameters of per-operative and postoperative morbidity in patients after NACT and in control patients, except for the necessary duration of artificial urine derivation in patients after NACT due to the fact that their surgery was more radical in the parametria. Administration of NACT regimen involving ifosfamide / cisplatin (IP) improved surgical conditions in the bulky squamous cell carcinoma of the uterine cervix.
