RESUMO
OBJECTIVE: To investigate the impact of cumulative cisplatin dose on clinical outcomes in locally advanced cervical cancer patients undergoing definitive chemoradiotherapy. METHODS: A retrospective analysis was conducted on 654 patients with stage IB3-IVA disease treated with definitive chemoradiotherapy. Radiotherapy was applied as external beam pelvic with or without para-aortic radiotherapy and brachytherapy. Concomitant chemotherapy was in the form of weekly or 3 weekly cisplatin. Data on demographics, treatment protocols, cumulative cisplatin dose, adverse effects, and survival outcomes were collected. Statistical analyses, including univariate and multivariate Cox regression models, were used to assess factors influencing progression free survival and overall survival. RESULTS: The median cumulative cisplatin dose was 210 mg (range 40-320), and ≥200 mg in 503 (76.9%) patients. Median follow-up was 35 months (range 1-150). The 5 year progression free survival and overall survival rates were 66.9% and 77.1%, respectively. Multivariate analysis identified poor performance status, non-squamous cell histology, presence of lymph node metastases, and hemoglobin <10 g/dL before chemoradiotherapy as poor prognostic factors for both progression free survival and overall survival in the whole group. When stage III cases were evaluated separately, the cumulative cisplatin dose <200 mg was found to be a significant poor prognostic factor in overall survival (hazard ratio 1.79, 95% confidence interval 1.1 to 3.0, p=0.031). CONCLUSION: Our study showed that a cumulative cisplatin dose >200 mg, particularly in patients with lymph node metastases, significantly improved overall survival. Factors such as anemia, toxicity related challenges, and comorbidities were identified as critical considerations in treatment planning. These findings emphasize the balance between maximizing therapeutic efficacy and managing toxicity, guiding personalized treatment approaches for locally advanced cervical cancer.
RESUMO
A woman in her 40s presented with exertional dyspnoea with an absence of haemoptysis, cough, fever and weight loss. The patient had a medical history of extensive endometriosis. Investigations revealed a large right-sided pleural effusion. The effusion was aspirated and was exudative in nature.A contrast-enhanced CT thorax was performed to help exclude dual pathology. The only positive finding was bilateral breast nodules, subsequently found to be benign fibroadenomas on histological analysis of biopsy samples.After malignancy was ruled out as a cause, the patient was referred for medical thoracoscopy for a biopsy and other investigations. Histology demonstrated the presence of endometrial tissue in the pleura and thereby confirmed the diagnosis of thoracic endometrial syndrome.Video-assisted thoracoscopic surgery repair of diaphragm and talc pleurodesis was carried out in an uncomplicated procedure and the patient was discharged with good recovery.

Endometriosis may contribute to Mullerian adenosarcoma development but makes diagnosis challenging given similar symptoms. Survival benefit has not been definitively shown for chemotherapy, hormonal therapy, or radiotherapy, consolidating surgery as the mainstay treatment. Local excision may be a treatment option for patients with confined tumors wishing to preserve their fertility.
RESUMO
BACKGROUND: Little is known about real-world patterns of chemotherapy use in patients with cervical cancer. OBJECTIVE: To examine the patterns of chemotherapy use in patients with cervical cancer METHODS: We identified patients with cervical cancer in the IBM MarketScan Database who underwent primary hysterectomy or radiation therapy between 2011 and 2020 and described their treatment in the primary setting and at first recurrence. RESULTS: We identified 5390 patients: 2667 (49.5%) underwent primary hysterectomy and 2723 (50.5%) primary radiotherapy. Among patients who underwent primary hysterectomy, 979 (36.7%) received adjuvant radiation, and 617 (23.1%) received primary chemotherapy. The most common chemotherapy regimens were single-agent platinum (51.7%), platinum combination therapy (42.9%), and non-platinum (3.4%). Among patients treated with primary radiation, 73.6% received primary/concurrent chemotherapy, either platinum alone (66.4% of those who received chemotherapy), platinum combinations (32.2%), or non-platinum (1.4%). The median duration of primary chemotherapy was 1.2 months. Therapy for recurrent cervical cancer was initiated in 959 patients. The most common regimens were platinum combination (63.9%), non-platinum cytotoxic agents (16.5%), single-agent platinum (14.9%), targeted therapy with bevacizumab (6.0%), and immunotherapy with pembrolizumab (3.2%). Overall, the proportion of patients treated with single-agent platinum therapy increased from 17.4% in 2011 to 32.1% in 2019, while platinum combinations decreased from 64.1% to 41.5% over the same years. Use of non-platinum agents increased from 18.5% in 2011 to 32.9% in 2018 and 26.4% in 2019. CONCLUSIONS: Platinum-based chemotherapy is the most commonly used therapy in patients with cervical cancer in the primary setting and at the time of recurrence. The rate of use of non-platinum agents at first recurrence has increased over time.

In the last decade, we have witnessed important advances in novel therapeutics in the management of gynecologic cancers. These studies have built on the findings from preexisting data and have provided incremental contributions leading to changes that have not only impacted the accuracy of cancer detection and its metastatic components but also led to improvements in oncologic outcomes and quality of life. Key landmark trials have changed the standard of care in cervix, uterine, and ovarian cancer. A number of these have been controversial and have generated significant debate among gynecologic oncologists. The main objective of this review was to provide an overview on each of these trials as a reference for immediate and consolidated access to the study aims, methodology, results, and conclusion.

Laminin receptor 1 (LAMR) may have a role in the progression of premalignant squamous epithelial lesions to cervical cancer. Therefore, we aimed to investigate the expression of laminin receptor 1 (LAMR) in normal, premalignant, and malignant tissues of the uterine cervix. Paraffin blocks of 129 specimens with the diagnoses of normal cervical tissue (n = 33), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2 (n = 14), CIN 3 (n = 28), and squamous cell carcinoma (n = 24) were immunohistochemically stained with LAMR antibody and its expression percentage, pattern, and intensity in these tissues were assessed. Compared to the other groups, the nonstaining with LAMR was highest in low grade squamous intraepithelial lesion (LSIL) (p < 0.0001). LAMR expression, which was positive in less than 50% of cells with weak staining, increased significantly between normal cervical epithelium and high-grade squamous intraepithelial lesion (HSIL) or invasive carcinoma, as well as between LSIL and HSIL (p < 0.0001). Between LSIL and invasive carcinoma, a significant increment was also observed for weak staining in less than 50% of cells (p < 0.001). LAMR expression, which was positive in more than 50% of cells with strong staining, was significantly higher in normal cervical tissue compared to the other groups (p < 0.0001). Disease progression related gradual increment of LAMR expression from normal cervical epithelium or LSIL towards HSIL or cervical cancer reveals that LAMR may play an important role in the transition from premalignant to malignant state in cervical lesions.

OBJECTIVE: We sought to evaluate the oncologic outcomes of simple hysterectomy in patients with low-risk early-stage cervical cancer (tumors ≤2 cm with limited stromal invasion). METHODS: This study was registered in PROSPERO (registration number CRD42023433840) following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) checklist. MEDLINE (through Ovid), EmMBASEbase, and Cochrane Central Register of Controlled Trials were searched from inception until June 2023. Randomized controlled trials and observational studies with two arms of comparison (simple hysterectomy with lymph node assessment vs radical hysterectomy with lymph node assessment) in patients with low-risk early-stage cervical cancer were considered. RESULTS: The search identified 1270 articles; eighteen studies were considered potentially eligible after removing duplicates, and four met the selection criteria. Three studies were randomized controlled trials, and the other was a retrospective cohort study. In total, 981 patients were included. There were 485 (49.4%) and 496 (50.6%) patients in the simple hysterectomy and radical hysterectomy groups, respectively. Simple hysterectomy with lymph node assessment was not associated with a higher risk of death at 5 years (RR 0.98, 95% CI: 0.31 to 3.10; I2=0%, two randomized controlled trials, 141 patients, for an absolute risk reduction of zero percentage points [95% CI -9.0 to 9.0]), pelvic recurrence at 3 years (97.5% and 97.8% for simple hysterectomy and radical hysterectomy, respectively, p=0.79), and overall recurrence at 3 years (95 %% and 100% for simple hysterectomy and radical hysterectomy, respectively, p=0.30). CONCLUSION: Simple hysterectomy with lymph node evaluation for low-risk early-stage cervical cancer is not associated with a detrimental effect on oncologic outcomes and has a better morbidity profile.

BACKGROUND: Lymphatic involvement is the most important prognostic factor in early-stage cervical cancer. Sentinel lymph node biopsy is a viable alternative to systematic lymphadenectomy and may identify metastases more precisely. OBJECTIVE: To compare two tracers (indocyanine green and patent blue) to detect sentinel nodes. METHODS: A single-center, retrospective study of women treated due to early-stage cervical cancer (International Federation of Gynecology and Obstetrics 2009 IA1 with lymphovascular invasion, IA2, and IB1). Location and tracer of all detected sentinel nodes had been documented for a prospective, multicenter trial (SENTIX trial). All sentinel nodes were sent to frozen section and final analysis through ultrastaging using a standard protocol. RESULTS: Overall, 103 patients were included. Bilateral detection rate for indocyanine green (93.2%) was significantly higher than for blue dye (77.7%; p=0.004). Their combined use significantly increased the bilateral detection to 99.0% (p=0.031). While 97.4% of all sentinel nodes were located below the common iliac vessels, no para-aortic nodes were labeled. Simultaneous bilateral detection with both tracers was found in 71.8% of the cases, of which the sentinel nodes were identical in 91.9%. Nine positive nodes were detected among seven patients (6.8%), all marked with indocyanine green while patent blue labeled six. Frozen section failed to detect one of three macrometastases and three of four micrometastases (sensitivity 43%; negative prediction value 96%). CONCLUSION: Anatomical distribution and topographic localization of the sentinel nodes obtained with these tracers were not different. Indocyanine green provided a significantly higher bilateral detection rate and had superior sensitivity to detect positive nodes compared with patent blue. Combining indocyanine green and blue dye increased the bilateral detection rate significantly.

Melanoma of the uterine cervix is an exceedingly rare malignancy that has high recurrence rates and distant metastases. In general, surgery is the preferred treatment for this tumor, and depending on stage additional consideration to radiotherapy and chemotherapy. Immunotherapy has emerged as a new treatment option in this context. The aim of this study was to report a case of melanoma of the uterine cervix that progressed rapidly to death while the patient was undergoing immunotherapy with nivolumab. A 39-year-old woman presented with an amelanotic ulcerated lesion of the uterine cervix in February of 2023. Histopathology study demonstrated melanoma of the uterine cervix. Treatment was initiated with surgery. Two months after cancer diagnosis, the tumor board decided to initiate adjuvant treatment with nivolumab. After four cycles of immunotherapy, progression of the disease occurred with death of the patient within six months of follow-up. The rare case presented illustrates the aggressive natural history of the tumor and possible use of immunotherapy in this context, despite current evidence that response to nivolumab is less effective in cervical melanoma than in skin melanoma.
RESUMO
We report a rare case of a retroperitoneal uterus-like mass communicating with the endocervix, which presented as abdominal pain and bloating associated with severe irregular vaginal and postcoital bleeding. Our patient did not have any structural abnormalities of the urogenital system or otherwise, which makes a müllerian defect unlikely in our case. Based on the diagnostic criteria for the choristoma, that theory would be excluded here as the mass communicated with the endocervix. This strengthens the theory of metaplasia, under the effect of oestrogen and accelerated by the hyperoestrogenic state of pregnancy as the most likely postulate for our patient. Although the uterus-like mass is not commonly reported, it should be considered as a possible differential for pelvic masses.

BACKGROUND: Ninety percent of cervical cancer (CC) diagnoses and deaths occur in low and middle-income countries (LMICs). Especially in these countries, where human and material resources are limited, there is a need for real-time screening methods that enable immediate treatment decisions (i.e., 'see and treat'). OBJECTIVE: To evaluate whether handheld vital microscopy (HVM) enables real-time detection of microvascular alterations associated with cervical intraepithelial neoplasia (CIN) and CC. METHODS: A cross-sectional study was conducted in an oncologic hospital and outpatient clinic, and included ten healthy controls, ten women with CIN, and ten women with CC. The microvasculature was assessed in four quadrants of the uterine cervix using HVM. The primary outcome was the presence of abnormal angioarchitecture (AA). Secondary outcomes included capillary loop density (CD), total vessel density (TVD), functional capillary density (FCD), and the proportion of perfused vessels (PPV). RESULTS: 198 image sequences of the cervical microvasculature were recorded. Compared to healthy controls, significantly more abnormal image sequences were observed in women with high-grade CIN (11 % vs. 44 %, P < 0.001) and women with CC (11 % vs. 69 %, P < 0.001). TVD, FCD, and PPV were lower in women with CIN and CC. CONCLUSIONS: HVM enables easy, real-time, non-invasive assessment of cervical lesions through the detection of microvascular alterations. Thereby, HVM potentially provides an opportunity for point-of-care screening, which may enable immediate treatment decisions (see and treat) and reduce the number of unnecessary surgical interventions.

Abstract Objective: To describe Top-hat results and their association with margin status and disease relapse in a referral facility in Brazil. Methods: A retrospective study of 440 women submitted to LEEP to treat HSIL, in which 80 cases were complemented immediately by the top hat procedure (Top-hat Group - TH). TH Group was compared to women not submitted to Top-hat (NTH). The sample by convenience included all women that underwent LEEP from January 2017 to July 2020. The main outcome was the histological result. Other variables were margins, age, transformation zone (TZ), depth, and relapse. The analysis used the Chi-square test and logistic regression. Results: The TH Group was predominantly 40 and older (NTH 23.1% vs. TH 65.0%, p<0.001). No difference was found in having CIN2/CIN3 as the final diagnosis (NTH 17.0% vs. TH 21.3%, p=0.362), or in the prevalence of relapse (NTH 12.0% vs. TH 9.0%, p=0.482). Of the 80 patients submitted to top hat, the histological result was CIN2/CIN3 in eight. A negative top hat result was related to a negative endocervical margin of 83.3%. A CIN2/CIN3 Top-hat result was related to CIN2/CIN3 margin in 62.5% (p=0.009). The chance of obtaining a top hat negative result was 22.4 times higher (2.4-211.0) when the endocervical margin was negative and 14.5 times higher (1.5-140.7) when the ectocervical margin was negative. Conclusion: The top hat procedure did not alter the final diagnosis of LEEP. No impact on relapse was observed. The procedure should be avoided in women of reproductive age.
RESUMO
Resumen OBJETIVO: Determinar la prevalencia de alteraciones en la citología anal, infección anal por virus del papiloma humano y en la neoplasia intraepitelial anal; además, explorar los factores de riesgo y los serotipos asociados en pacientes con lesión intraepitelial cervical de alto grado, a partir de la hipótesis de que esta población tiene mayor riesgo de lesiones precursoras o cáncer anal. MATERIALES Y MÉTODOS: Estudio observacional, descriptivo y transversal, con componente analítico, efectuado en pacientes con diagnóstico de lesión intraepitelial cervical de alto grado (LIEAG) en dos instituciones de salud: una privada y otra pública de Bogotá, atendidas entre enero de 2017 y febrero de 2018. Se efectuó un muestreo no probabilístico, por conveniencia. RESULTADOS: Se incluyeron 119 participantes, en 4 de ellas se evidenció, en la citología anal, el hallazgo de células anormales en el tejido que reviste la parte exterior del cuello uterino. Se encontraron 14 anoscopias anormales que dieron una prevalencia de neoplasia intraepitelial anal del 6.7%. Siete eran neoplasia intraepitelial anal de bajo grado y una de alto grado. Se encontró infección por VPH anal en 45 participantes (37.8%) y se detectaron genotipos de VPH-AR en 29 participantes (24.4%). Más de 3 compañeros sexuales, más de 3 hijos y tener menos de 21 años antes del primer embarazo tuvieron un valor de p < 0.05 que confiere mayor riesgo de infección por VPH anal. CONCLUSIÓN: Es importante establecer en Colombia protocolos para la detección de la neoplasia intraepitelial anal en grupos de alto riesgo, como las pacientes con neoplasia intraepitelial cervical o cáncer de cuello uterino, e incentivar el adiestramiento en la anoscopia de alta resolución en especialistas relacionados con el diagnóstico de patología anogenital.
Abstract OBJECTIVE: To determine the prevalence of alterations in anal cytology, anal human papillomavirus infection, and anal intraepithelial neoplasia, and to explore the risk factors and associated serotypes in patients with high-grade cervical intraepithelial lesion, based on the hypothesis that this population is at higher risk for precancerous lesions or anal cancer. MATERIALS AND METHODS: Observational, descriptive, cross-sectional study, with analytical component, performed in patients diagnosed with high-grade cervical intraepithelial lesion (HG-CIL) in two health institutions: one private and one public in Bogota, visited between January 2017 and February 2018. A non-probabilistic sampling was performed, by convenience, with a sample calculated in 124 patients. RESULTS: 119 participants were included, in 4 of them it was evidenced in the anal cytology, the finding of abnormal cells in the tissue lining the outside of the cervix. Fourteen abnormal anoscopies were found, giving a prevalence of anal intraepithelial neoplasia of 6.7%. Seven were low-grade anal intraepithelial neoplasia and one was high-grade. Anal HPV infection was detected in 45 participants (37.8%) and HR-HPV genotypes were detected in 29 participants (24.4%). More than 3 sexual partners, more than 3 children and being younger than 21 years before first pregnancy had a p-value < 0.05 conferring an increased risk of anal HPV infection. CONCLUSION: It is important to establish protocols in Colombia for the detection of anal intraepithelial neoplasia in high-risk groups, such as patients with cervical intraepithelial neoplasia or cervical cancer, and to promote training in high-resolution anoscopy in specialties related to the diagnosis of anogenital pathology.
RESUMO
OBJECTIVE: Our study used human papillomavirus (HPV) genotyping to assess the disease occurrence probability in women with a low-grade squamous intraepithelial lesion (LSIL) without histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+). METHODS: This study investigated CIN2+ incidence in 1986 women from January 2005 to August 2016, including 1123 with LSIL who were histology-proven negative and 863 with LSIL who were histology-proven CIN1. Baseline high-risk HPV (HR-HPV) status was determined using the hybrid capture II assay (HC2), and HR-HPV genotype was determined using the HPV DNA chip test (HDC). RESULTS: Among 1986 women, the HC2 yielded positive results in 1529 (77.0%), while the HDC identified 1624 (81.8%). Thus, the overall HDC and HC2 agreement was 93.2%. Overall, 169 (8.5%) patients developed CIN2+. The 5-year cumulative CIN2+ incidence rates for HPV-16, HPV-18, HPV-31, and HPV-33 were 11.8%, 9.9%, 16.3%, and 16.1%, respectively. Multivariate analysis revealed that HPV-16 (HR 1.637, 95% CI 1.064 to 2.520, p=0.025), HPV-31 (HR 1.845, 95% CI 1.051 to 3.238, p=0.033), and HPV-33 (HR 2.272, 95% CI 1.235 to 4.183, p=0.008) were significantly associated with CIN2+ development. CONCLUSION: Among women with LSIL, those who test positive for HPV-16, HPV-31, or HPV-33 may require more rigorous follow-up because of a higher CIN2+ risk.

Objectives: As a convenient and economical method of screening cervical cancer and precancerous pathologies, the Papanicolaou smear (Pap smear) has been most widely used. Nevertheless, it requires cytological changes for making diagnoses and reportedly has a high false-negative rate. In this study, the usefulness of the human papillomavirus (HPV) DNA chip test as a complementary method that can compensate for the defect of the Pap smear was investigated. Material and Methods: Of the 6516 patients who simultaneously underwent a Pap smear and an HPV DNA chip test at Chonnam National University Hospital between January 2015 and December 2016, 1897, an initial PAP smear-negative patients who had undergone an additional Pap smear during their 2-year follow-up period were selected for this study. Of the subject patients, 281 underwent a cervical biopsy. Results: The Pap smear follow-up of an initial Pap smear-negative subjects showed 53 (75.7%) HPV high-risk positive cases in the cytology low-grade lesion group (70 cases) and 46 (97.8%) HPV high-risk positive cases in the cytology high-grade lesion group (47 cases). The 281 biopsy cases included 67 biopsy low-grade lesion cases and 74 biopsy high-grade lesion cases, of which there were 45 (67.2%) and 67 (90.5%) HPV high-risk positive cases, respectively. The follow-up cytology on the high-risk HPV-positive subjects showed that the ratio of their high-grade lesions was 260.8 times greater than that of the high-risk HPV-negative subjects (OR = 260.8 and 95% CI: 36.1 and 1886.1); and their biopsy showed that the ratio of their high-grade lesions was 102.7 times greater than that of the HPV-negative subjects (OR = 102.7 and 95% CI: 14.0 and 753.3). Conclusion: The complementary use of the HPV DNA chip test may be useful in increasing the accuracy of screening examinations for the early diagnosis of uterine cervix cancer when combined with the Pap smear.
RESUMO
BACKGROUND: The prevalence of different HPV types, especially HPV16 and 18 in cervical cancer in patients diagnosed 2019-2023 in Stockholm was compared to corresponding data from 2003-2008 before the introduction of HPV vaccination in Sweden. MATERIAL AND METHODS: Cervical cancer samples from 125 patients diagnosed 2019-2023 in Stockholm were analysed for 27 HPV types by multiplex assay and the HPV type prevalence data was compared to data obtained in 154 cervical samples from 2003-2008. RESULTS: Patient median age was higher 2019-2023 compared to 2003-2008 (55-years vs. 42-years, p = 0.046). Overall HPV prevalence was 93.6%, HPV16 and 18 accounted for 62.2% of all squamous cell carcinoma cases (SCC) and 63.6% of all adenocarcinoma cases (ADC) vs. 92.9%, 69.7% and 88.6% respectively 2003-2008. CONCLUSION: The joint prevalence of HPV16 and 18 in SCC and ADC tended to be slightly lower in 2019-2023 as compared to 2003-2008, but the difference was not statistically significant.
