RESUMO

The incidence of cancer during pregnancy is steadily rising because of the postponement of plans for childbearing. One of the most common cancers diagnosed during pregnancy is cervical cancer. Diagnosis of most cases usually occurs in the early stages, but there are still cases of tumors staged IB2 and higher. In these cases, the treatment strategy entails administration of neoadjuvant chemotherapy. However, a universally recognized standardized regimen for neoadjuvant chemotherapy treatment of cervical cancer during pregnancy has yet to be established. The chemotherapy agents used during treatment are known for their fetal adverse effects. The aim of the therapy is to attain full-term pregnancy while minimizing fetal toxicity and decreasing tumor size. In this case report, we present a first-time sequential chemotherapy administration to minimize the cumulative toxicity of individual regimens and demonstrate the benefits for the patient and fetus.

RESUMO

AIM: To review the changes in the new version of the FIGO 2023 staging system for endometrial cancer. METHODS AND RESULTS: The new FIGO 2023 endometrial cancer staging system provides key updates for the diagnosis and treatment of endometrial cancer. An important step in diagnosis is molecular classification, which allows more accurate risk stratification for recurrence and the identification of targeted therapies. The new staging system, based on the recommendations of the international societies ESGO, ESTRO and ESP, incorporates not only the description of the pathological and anatomical extent of the disease, but also the histopathological characteristics of the tumour, including the histological type and the presence of lymphovascular space invasion. In addition, the staging system uses molecular testing to classify endometrial cancers into four prognostic groups: POLEmut, MMRd, NSMP and p53abn. Each group has its own specific characteristics and prognosis. The most significant changes have occurred in stages I and II, in which the sub-staging better reflects the biological behaviour of the tumour. This update increases the accuracy of prognosis and improves individualized treatment options for patients with endometrial cancer. CONCLUSION: The updated FIGO staging of endometrial cancer for 2023 incorporates different histologic types, tumour features, and molecular classifications to better reflect the current improved understanding of the complex nature of several endometrial cancer types and their underlying bio logic behaviour. The aim of the new endometrial cancer staging system is to better define stages with similar prognosis, allowing for more precise indication of individualised adjuvant radiation or systemic treatment, including the use of immunotherapy.

RESUMO

OBJECTIVE: The aim of this study was to determine how often changes the stage of the tumour in definitive histology against preoperative clinical stage in patient cohort with diagnosed endometrial cancer. METHODS: We evaluated prospectively a cohort of 166 patients with endometrial cancer. They all underwent abdominal hysterectomy, bilateral salpingo-oophorectomy, sentinel lymph node biopsy. Patients with high-risk tumours also pelvic lymfadenectomy. We collected data of preoperative diagnostic biopsy and postoperative definitive histology. The data were statistically processed. RESULTS: Detection of sentinel lymph node was successful in 71.1%, bilateral successful detection was in 40.6%. Discrepancy of tumour grade between preoperative biopsy and definitive histology was generally 31.4%. Upgrading of the tumour was in 22 (14.4%) cases, downgrading in 26 (17%) cases. Upgrade from low-risk to high-risk group of tumours was noticed in eight cases. Histopathological tumour type changed in 6.6%, 4.6% moved to histopathologic high-risk group. The tumour stage changed in definite histology in 57.3%, in 19.2% of cases moved from stage low/intermediate-risk group to intermediate-high/high-risk disease group. CONCLUSION: Correct assessment of preoperative clinical stage and histological grade of endometrial cancer is burdened with a high inaccuracy rate. A lot of cases is up-staged after surgical staging and moved to intermediate-high/high-risk disease group. Results confirm the importance of oncogynaecologic centre II. evaluation of histopathology findings from diagnostic biopsies made in referring hospitals. Sentinel lymph node biopsy should be performed even in clinically low/intermediate-risk disease group.

RESUMO

OBJECTIVE: A review of current knowledge on the efficacy of human papillomavirus (HPV) vaccination in preventing recurrent severe cervical lesions after excisional surgical treatment. METHODS AND RESULTS: HPV infection is necessary for the development of most cervical precancerous lesions and cervical cancers. Currently, three prophylactic vaccines against HPV infection are available on the market: bivalent Cervarix, quadrivalent Gardasil (formerly Silgard) and nonavalent Gardasil9. All three prophylactic vaccines show high effect in preventing the development of precancerous lesions. The highest efficacy is achieved in the HPV naive population. The surgical excision of severe cervical precancers is the standard approach. However, guidelines regarding HPV vaccination at the time of conisation are not clearly determined. Women diagnosed with severe cervical lesions have mostly not been vaccinated against HPV so far. Therefore, it is beneficial to understand the importance and efficacy of HPV vaccination at the time of conisation in preventing recurrent precancerous lesions. The exact value of HPV vaccination in the context of surgical excision of precancerous lesions remains unclear, but vaccination is definitely valuable in reducing the risk of recurrence. Vaccination timing seems to be more favorable before surgery. However, the ideal timing of vaccination is not established. Some of these questions are likely to be answered by the results of ongoing randomized controlled trials. CONCLUSION: Adjuvant HPV vaccination in the setting of surgical treatment for cervical precancerous lesion is significantly associated with a reduced risk of recurrence. HPV vaccination should be strongly considered as adjuvant therapy, especially in young patients undergoing conisation for a severe cervical lesion.

RESUMO

INTRODUCTION: The standard procedure in cervical cancer is radical hysterectomy and pelvic lymphadenectomy (PLND). Because of the increasing age of women bearing children, fertility has become a major challenge. We present pregnancy results after less radical fertility-sparing surgery in women with IA1, LVSI positive, IA2 and IB1 (<2 cm, infiltration less than half of the cervical stroma). MATERIALS AND METHOD: All women (n = 91) underwent laparoscopic sentinel lymph node mapping with frozen section followed by PLND and "selective parametrectomy" (removal of afferent lymphatic channels from the paracervix) if sentinel nodes (SLN) are negative. If lymph nodes were verified negative by definitive histopathology, patients were treated by simple trachelectomy (IB1) or large cone (IA1/IA2) biopsy 1 week after primary surgery. RESULTS: From 1999 to 2018, 91 women were enrolled in the study (median age 29.1 years, range 21-40). Fertility was spared in 76 (83.5%) women; 13 (17.1%) women did not plan future pregnancy and 63 (82.9%) had pregnancy desires. Fifty-four of 63 women conceived (pregnancy rate 85.7%) and 48 of 63 delivered 58 babies (delivery rate 76.2%). Thirty-nine women delivered in term (67.2%): 13 women between 32 and 36 + 6 weeks of pregnancy, 3 between 28 and 31 + 6 weeks and 3 between 24 and 27 + 6 weeks. Only one woman still plans pregnancy. One woman is currently pregnant. CONCLUSION: The goal of fertility-sparing surgery is to produce good oncological results and promising pregnancy outcomes. Pregnancy results after less radical fertility-sparing procedures show promise (pregnancy rate 82.9% and delivery rate 76.2%).

RESUMO

OBJECTIVE: Epidemiology and evaluation of the importance of surgical margins in the treatment of vulvar H-SIL - analysis of own data. MATERIAL AND METHODS: The prospective study included women dia-gnosed with HPV-associated vulvar epithelial neoplasia from 10/2016 to 1/2022. A total of 65 women were included. After surgical treatment, the women were distributed to groups according to surgical margins and were followed-up at regular intervals. RESULTS: Seventeen women (26%) dia-gnosed with HPV-associated vulvar intraepithelial neoplasia were under 49 years, whereas 48 women (74%) were older than 49 years. Recurrence rates of HPV-associated precancers were 12.3%, 1.5% and 3.1% in excisions with positive margins up to 1mm peripheral margins and 1-3mm peripheral margins, respectively. The risk of recurrence when the lesion reaches the margin is statistically significant, compared to a healthy margin of 1-3mm. CONCLUSION: Keeping the minimal healthy margin (1-3mm) seems to be an acceptable risk of recurrence of HPV-associated vulvar intraepithelial neoplasia with positive cosmetic effect and minimal risk of disturbing the psychosexual functions of women. Long-term regular follow-up is necessary.

RESUMO

We report a case of a 49-year-old female with desmoplastic small round cell tumor of the uterus (DSRCT). Histologically, in some areas the tumor showed typical features with ample desmoplastic stroma, while in other areas the tumor cells diffusely infiltrated myometrium with only focal desmoplastic reaction. Immunohistochemically, the tumor cells showed diffuse positivity for desmin, CD56, CD57, EMA and cyclin D1. Focal positivity was present for antibodies against cytokeratin AE1/3, BerEP4, NSE, IFITM1 and CD10. The WT-1 antibody (against the N-terminus) showed cytoplasmic positivity in some tumor cells, while the nuclei were negative. P53 expression was wild-type. The Ki-67 index (MIB1 antibody) was about 55%. Other markers examined including transgelin, myogenin, synaptophysin, chromogranin, h-caldesmon, PAX8, and CD117 were all negative. NGS analysis revealed a fusion transcript of the EWSR1 and WT1 genes. DSRCT of the uterus is a rare neoplasm, as only two cases have been reported so far. However, only one of these cases was examined molecularly with a confirmation of the characteristic EWSR1-WT1 fusion. We report a second case of molecularly confirmed DSRCT of the uterus and discuss its clinical features, differential diagnosis and the significance of molecular testing.

RESUMO

OBJECTIVE: The objective of this systematic review was to assess the oncologic and fertility outcomes of patients with cervix-confined cancer >4 cm who underwent neo-adjuvant chemotherapy followed by fertility-sparing surgery. METHODS: This study was registered in PROSPERO (registration number CRD42021254816). PubMed/MEDLINE, ClinicalTrials, EMBASE, Cochrane Central Register of Controlled Trials, SCOPUS, and OVID databases were searched from inception to July 2021. The included patients were those with cancer confined to the cervix and tumor diameter >4 cm (International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB3) with squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma who underwent intra-venous neo-adjuvant chemotherapy followed by successful fertility-sparing surgery. RESULTS: The initial search identified 2990 articles. A total of 40 patients from 11 studies had attempted fertility preservation surgery (conization, simple or radical trachelectomy) and in 26 patients (65%) it was successful. All patients received platinum-based chemotherapy. A complete pathological response occurred in 56% of patients and two patients (7.7%) had a recurrence. The 4.5-year disease-free survival was 92.3% and the 4.5-year overall survival rate was 100%. Of six patients who tried to conceive, four (67%) achieved at least one pregnancy and three of the five pregnancies (60%) were pre-term deliveries (all after radical trachelectomy). All patients with recurrence received cisplatin and ifosfamide instead of cisplatin and paclitaxel, underwent non-radical surgery, and had residual disease in the final specimen. CONCLUSIONS: Evidence for fertility-sparing surgery after neo-adjuvant chemotherapy in patients with cervical cancer and tumors >4 cm is limited, and this approach should be considered as an experimental intervention. As the use of non-radical surgery could be a risk factor, if neo-adjuvant chemotherapy is used, patients should undergo fertility-sparing radical surgery.

RESUMO

INTRODUCTION: The standard procedure in cervical cancer is radical hysterectomy (RH) and pelvic lymphadenectomy (PLND). Because of the increasing age of women at childbirth, fertility becomes a major challenge. We present 20 years of experience with two-step less radical fertility-sparing surgery in women with IA1, LVSI positive, IA2 and IB1 (<2 cm, infiltration less than half of stromal invasions. MATERIALS AND METHOD: Preoperative workout consisted of histopathological diagnosis and magnetic resonance imaging along with ultrasonographic volumetry. We then performed laparoscopic sentinel lymph node mapping (SLNM) with frozen section (FS) followed by PLND and "selective parametrectomy" (removal of afferent lymphatic channels from the paracervix) in case of a negative result. If verified by definitive histopathology, patients were treated by simple trachelectomy (IB1) or large cone (IA1/IA2) biopsy 1 week after primary surgery. RESULTS: From 1999 to 2018, 91 women were enrolled in the study (median age 29.1 years, range 21-40). Of these 91 women, 51 (56.0%) were nulliparous. The detection rate of SLNs was 100% per patient and the specific side detection rate 96.7%. Positive lymph nodes were diagnosed in nine cases (9.8%). These women then underwent RH. Fertility was spared in 80 women but 4 recurred locally (5.0%). The mortality rate was 0.0%. The median follow-up was 149 months. CONCLUSION: Less radical fertility-sparing surgery with SLNM is safe in cervical cancers <2 cm at the largest diameter and infiltrating less than half of the cervical stroma. The recurrence rate is acceptable with no mortality. Morbidity with this procedure is low. Extended and accurate follow-up is necessary and human papillomavirus - high risk (HPV-HR tests seem to be useful in such follow-up assessment.

RESUMO

Because of a notable increase in age at delivery, the incidence of malignancy diagnosed during pregnancy has substantially increased. This review aims to summarize the literature and expert knowledge on gynecologic cancers diagnosed in pregnancy regarding epidemiology, examination and staging procedures, description of treatment modalities and management of gynecological malignancies with special interest in cervical and ovarian cancer. Thorough attention is paid to the surgery and chemotherapy administration for early-stage cervical cancer diagnosed during pregnancy.

RESUMO

The number of patients given neoadjuvant chemotherapy (NAC) followed by fertility-sparing surgery in cervical cancer is still scarce. Only a few centres perform these procedures, and thus, such procedures remain largely in the experimental stage. Patients that do not fulfil the criteria for standard fertility-sparing procedure can be included in studies with NAC followed by fertility-sparing procedure. We must consider that both oncological and pregnancy outcomes are important. Patients with only microscopic disease after NAC are apparently the best candidates for fertility-sparing surgery. Current data are not sufficient to identify the optimal procedure after NAC [abdominal radical trachelectomy (ART) or vaginal radical trachelectomy (VRT) or simple trachelectomy]. Some evidence suggests that pregnancy outcome is better after simple trachelectomy as compared with VRT or ART. Long-term results regarding oncological outcome for this concept are still lacking. Adjuvant chemotherapy in patients with histopathological risk factors (lymphovascular space involvement (LVSI), macroscopic residual disease) would decrease a risk of recurrence.

RESUMO

OBJECTIVE: The aim of this study was to prospectively monitor the patients' quality of life (QoL) after vulvar cancer surgery. DESIGN: The design was prospective clinical study. SETTING: The study was set in the Department of Obstetrics and Gynecology, 2nd Medical Faculty of the Charles University and University Hospital Motol, Prague, Czech Republic. METHODS: A group of 36 patients underwent vulvar cancer surgery: 24 patients were subject to inguinofemoral lymphadenectomy (RAD) and 12 to sentinel lymph node biopsy. To evaluate QoL, the European Organisation for Research and Treatment of Cancer, QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 and 12 months after surgery. RESULTS: In patients with vulvar cancer after inguinofemoral lymphadenectomy, increased fatigue and impaired lymphedema were observed. In the group of patients after sentinel lymph node biopsy, none of the QoL variables worsened postoperatively. Comparing both groups 12 months after surgery, the RAD group had significantly worse outcomes in body image and cognitive functioning than the sentinel lymph node biopsy group.Patients in the RAD group, who received adjuvant radiotherapy (n = 13), had worse QoL in symptom experience (P < 0.05) at 6 and 12 months after the surgery than patients without radiotherapy (n = 11). CONCLUSIONS: Less radical surgery showed objectively better QoL results.

RESUMO

OBJECTIVE: 28 women under 35years with early-stage cervical cancer and strong desire for fertility preservation that do not fulfil standard criteria for fertility-sparing surgery (tumour larger than 2cm or with deep of infiltration more than half of stroma) were included in prospective study. METHODS: Dose-dense neoadjuvant chemotherapy (NAC) was performed on all 28 patients in 10-day intervals: cisplatin plus ifosfamide in squamous cell cancer (15 women-53.6%) or cisplatin plus doxorubicin in adenocarcinoma (13 women-46.3%). Patients underwent laparoscopic lymphadenectomy and vaginal simple trachelectomy after NAC. Patients with positive lymph nodes or inadequate free surgical margins underwent radical hysterectomy. RESULTS: No residual disease was found in 6 women (21.4%), microscopic disease was observed in 11 women (39.3%) and macroscopic tumour in was observed in 11 women (39.3%). Ten women (35.7%) lost fertility. Four women (20%) after fertility-sparing surgery recurred, two died of the disease (10%). Fertility was spared in 20 (71.4%) women and 10 of them became pregnant (50%). Eight women delivered ten babies (6 term and four preterm deliveries). There were two miscarriages in second trimester (in one woman) and one in first trimester. One woman underwent four unsuccessful cycles of IVF, one failed to become pregnant and one recurred too early. Two women underwent chemoradiotherapy for recurrence and lost chance for pregnancy. CONCLUSIONS: Downstaging by NAC in IB1 and IB2 cervical cancer before fertility-sparing surgery is still an experimental procedure, but shows some promise. Long-term results in relation to oncological outcome for this concept are still needed.

RESUMO

The status of regional lymph nodes is the most important prognostic factor in early cervical cancer patients. Pelvic lymph node dissections are routinely performed as a part of standard surgical treatment. Systematic pelvic lymphadenectomy is associated with short- and long-term morbidities. This review discusses single components of the sentinel lymph node mapping (SLNM) technique and results of the detection of sentinel lymph nodes. SLNM biopsy performed by an experienced team for small volume tumors (<2 cm) has high specific side detection rate, excellent negative-predictive value and high sensitivity. Uncommon lymphatic drainage has been reported in 15% of cervical cancer patients. There is sufficient data now to suggest that SLNM with 99mTc plus blue dye in the hands of a surgeon with extensive experience should prove to be an important part of individualized cervical cancer surgery and increase the safety of less radical or fertility-sparing surgery.

RESUMO

p16(INK4a) immunoprofiles of non-precancerous and dysplastic squamous cervical lesions were defined and applied to the reclassification of atypical immature squamous metaplasia (AIM). The immunoexpression of cytokeratin 17 (CK 17) in AIM was also evaluated. Totally, 295 cervical cone biopsies representing squamous metaplasia, reactive changes, koilocytosis, flat condyloma, CIN I, CIN II, CIN III and AIM were subjected to p16(INK4a) immunohistochemistry. AIM cases were analyzed using CK 17 antibody. Typical p16(INK4a) immunoprofiles for the metaplastic, LSIL/HPV and HSIL phenotypes were recorded and used for the categorization of AIM into particular phenotype groups. Results were correlated with CK 17 immunoexpression. All CIN II and CIN III lesions, all but one case of CIN I and all flat condylomas overexpressed p16(INK4a). Other non-precancerous lesions, including koilocytosis, were predominantly negative. Contrary to the sporadic and focal immunostaining, diffuse positivity was associated with the dysplastic features of the lesion. CIN II and CIN III were characterized by a diffuse, strong/weak, full-thickness staining, whereas CIN I showed a heterogeneous diffuse/focal, weak/strong, lower half positivity. One third of AIM lesions may be reclassified as HSIL, one third as LSIL/HPV and one third shows metaplastic phenotype. All AIM cases with metaplastic and LSIL/HPV phenotypes expressed CK 17 diffusely, whereas focal positivity slightly prevailed in AIM with HSIL phenotype. We conclude that p16(INK4a) immunohistochemistry is a supporting method for the differential diagnosis of cervical lesions, which may be especially useful for the reclassification of AIM. The efficacy of CK 17 immunohistochemistry seems to be controversial for these purposes.

RESUMO

OBJECTIVE: The endpoint of this prospective study is to evaluate response rate, survival and toxicity of high-dose density neoadjuvant chemotherapy (NAC) in bulky IB cervical cancer. MATERIAL AND METHODS: Between January 1998 and December 2009, 154 women were enrolled into study. Three patients were withdrawn. Of the 151 women, 119 had stage IB2 cervical cancer (78.8%) and 32 had stage IB1 cancer (21.2%) infiltrating the whole cervical stroma. Women received 3-4cycle cisplatin-75mg/m(2) and ifosfamide-2g/m(2) in cases of squamous-cell cancer or cisplatin-75mg/m(2) and doxorubicin-35mg/m(2) in adenocarcinoma every 10days and then underwent radical hysterectomy type III. Patients who had non-resectable disease underwent chemoradiotherapy. RESULTS: The overall response rate (reduction of tumor volume more than 50%) was 78.8%. Reduction of tumor volume less than 50% was seen in 15.2%. Tumor progression during chemotherapy occurred in nine patients (6.0%). There were positive lymph-nodes in 26 patients (18.3%) of the 142 that underwent surgery. 38 women underwent adjuvant radiotherapy (26.7%). There were 26 recurrences (17.2%). After surgery 20 women recurred from 142 (14.1%) and after primary radiotherapy 6 from 9 women recurred (66.7%). 25 of 151 women died from disease (16.5%). At the time of the study, surgery was performed in 118 women 5 or more years ago, 19 of them died of disease. Five-year specific survival is 83.6%. Grade 3-4 neutropenia was found in only 7.3% of the women, and grade 3-4 thrombocytopenia were found in 1.3%. CONCLUSION: High-dose density NAC appears to be feasible in the treatment IB bulky cervical cancer and toxicity is acceptable. Adjuvant radiotherapy was used only in 26.7%.

The prognosis of endometrial cancer (EC) is generally favorable, while lymph node status remains the most important prognostic factor. Sentinel lymph node mapping (SLNM) could help to find women in whom adjuvant therapy could be omitted. This review analyzes different techniques of injection and histopathologic elaboration of SLNM in EC. Results of studies on SLNM in ECs seem to be promising, but only a small series have been published so far. The studies are subdivided into three groups by the technique of injection (hysteroscopic, subserosal and cervical). Range of detection rate for SLNM varies from 45 to 100%. Hysteroscopic injection is not easy to learn; moreover, exact peritumoral injection in large tumors is often impossible. Subserosal administration of tracer is difficult during laparoscopic or robotic surgery. Cervical injection is quite a controversial technique because distribution of SLNs in ECs is different from cervical cancer; moreover, there is no large study using cervical injection with systematic pelvic and para-aortic lymphadenectomy.

RESUMO

BACKGROUND: Lower-limb lymphedema is one of the most disabling adverse effects of vulvar cancer surgery. Multifrequency Bioelectrical Impedance Analysis (MFBIA) is a modern noninvasive method to detect lymphedema. The first aim of this study was to prospectively determine the prevalence of secondary lower-limb lymphedema after surgical treatment for vulvar cancer using objective methods, circumference measurements and MFBIA technique. The second aim was to compare quality of life (QoL) before and 6 months after vulvar surgery. METHODS: Twenty-nine patients underwent vulvar cancer surgery in our study: 17 underwent inguinofemoral lymphadenectomy (RAD), and 12 underwent sentinel lymph node biopsy (CONS). Patients were examined before and 6 months after vulvar surgery by measuring the circumference of the lower limbs and with MFBIA. A control group of 27 healthy women was also measured. To evaluate QoL, the European Organisation for Research and Treatment of Cancer (EORTC) QoL questionnaires (QLQ-C30 and QLQ-CX24) were administered to patients before and 6 months after surgery. RESULTS: Using circumference measurement, 9 lymphedemas (31%) were diagnosed: 3 (25%) in the CONS and 6 (37.5%) in the RAD group (P = 0.69). After vulvar surgery, patients in the RAD group reported more fatigue and worsening of physical and role functioning. When comparing both groups, the RAD group had significantly worse parameters in social functioning, fatigue, and dyspnea. CONCLUSIONS: Lower radicality in inguinofemoral lymphadenectomy shows a trend toward lower morbidity and significantly improves QoL. Multifrequency Bioelectrical Impedance Analysis was tested in these patients as a noninvasive, objective method for lymphedema detection. Detection of lymphedema based on subjective evaluations proved to have an unsatisfactory sensitivity. Less radical surgery showed objectively better results in QoL.

RESUMO

Cancer of the cervix is the second most common cancer in women worldwide and the fourth leading cause of cancer mortality in women. Early cervical cancer stage IB1 includes a broad range of disease from clinically undetectable microinvasive cancer to bulky tumours that infiltrated the entire cervix. This article reviews the literature about risk factors and surgical radicality and fertility-sparing surgery in early cervical cancer. The review evaluates selection criteria, preoperative management and the most frequent surgical procedures used for individually tailored surgery for cervical cancer.
