RESUMO

The objective of this review is to summarize the current scientific evidence to formulate clinical recommendations regarding the classification, diagnostic approach, and treatment of rare histological subtypes of cervical cancer; neuroendocrine carcinoma, gastric-type mucinous adenocarcinoma, and glassy cell adenocarcinoma. These histological subtypes are generally characterized by their low frequency, aggressive biological behavior, certain chemoradioresistance, and consequently, high recurrence rates with a deleterious impact on survival. Molecular studies have identified several associated mutations in neuroendocrine carcinoma (PIK3CA, MYC, TP53, PTEN, ARID1A, KRAS, BRCA2) and gastric-type adenocarcinoma (KRAS, ARID1A, PTEN) that may serve as molecular targets. While adenocarcinomas are typically treated and classified based on squamous histology across early, locally advanced, and advanced stages, the treatment strategies for neuroendocrine carcinomas in early stages or locally advanced cases differ, particularly in the sequencing of administering chemotherapy, chemoradiotherapy, or surgery. The chemotherapy regimen is based on etoposide plus cisplatin (EP). Unlike squamous cell carcinomas, immune checkpoint inhibitors are yet to establish a standard role in the treatment of recurrent neuroendocrine carcinomas due to the absence of clinical trials. Regarding glassy cell adenocarcinomas and gastric-type adenocarcinoma, the potential use of immunotherapy in advanced stages/disease requires further evaluation through international collaborations, given the limited number of cases.

RESUMO

El carcinoma de cérvix constituye una causa rara de fiebre de origen desconocido (FOD). Se presenta el caso de una paciente femenina de 42 años de edad con fiebre de 80 días de evolución. Había estado ingresada en dos hospitales sin que se llegase a diagnosticar su causa. Se le habían administrado múltiples regímenes antibióticos sin lograrse remisión de la hipertermia. Fue remitida al hospital Hermanos Ameijeiras para continuar estudios en el protocolo de atención a pacientes con ese tipo de afección. Tenía anemia ferropénica y refería hipermenorrea. Al examen físico se encontró engrosamiento del cuello uterino al tacto vaginal y se visualizó una tumoración del mismo al examen con espéculo. La biopsia mostró un carcinoma y recibió tratamiento con radioterapia y quimioterapia con lo cual desapareció la fiebre. Se concluye que esta neoplasia puede presentarse a forma de fiebre prolongada producida directamente por el tumor primario, por lo que debe mantenerse un índice de sospecha en pacientes con FOD. Resulta importante tener en cuenta la asociación de fiebre y sangramiento vaginal como posible forma de presentación. Puede constituir una pista diagnóstica relevante para no perder tiempo. Este caso resalta la importancia de realizar un examen físico completo y exhaustivo a todos los pacientes(AU)

Carcinoma of the cervix is a rare cause of fever of unknown origin. We present the case of a 42-year-old female patient with fever of 80 days of evolution. She had been admitted to two hospitals without a diagnosis of the cause. She had been administered multiple antibiotic regimens without achieving remission of hyperthermia. She was referred to the "Hermanos Ameijeirasˮ Hospital to continue studies under the protocol for the care of patients with this type of condition. She had iron deficiency anemia and reported hypermenorrhea. Physical examination showed thickening of the cervix on vaginal examination and a tumor was visualized on speculum examination. The biopsy showed a carcinoma and she was treated with radiotherapy and chemotherapy, with which the fever disappeared. It is concluded that this neoplasm can present as a prolonged fever directly produced by the primary tumor, so an index of suspicion should be maintained in patients with fever of unknown origin. It is important to take into account the association of fever and vaginal bleeding as a possible form of presentation. It may constitute a relevant diagnostic clue to avoid wasting time. This case highlights the importance of performing a complete and thorough physical examination in all patients(AU)

RESUMO

Resumen El cáncer de cuello uterino ocupa el cuarto lugar dentro de las neoplasias de origen ginecológico a nivel global, representando un 85% de los casos en países en vías de desarrollo. Las metástasis cutáneas de origen ginecológico son altamente infrecuentes, observándose con mayor frecuencia en las neoplasias malignas de ovario, seguidas del adenocarcinoma endometrial y de cuello uterino y, menos frecuentemente, las de subtipo escamocelular. En la actualidad, existen alrededor de 80 reportes de casos citados en la literatura de metástasis cutáneas secundarias a un carcinoma de cuello uterino; sin embargo, ninguno con localización en la piel del cuello que se origine de un subtipo histológico escamocelular. En Colombia, no hay casos reportados hasta la fecha. Se presenta el caso de una paciente de 43 años que consulta por sangrado vaginal, dolor abdominal y una extensa placa tumoral exofítica de aspecto metastásico en la piel del cuello y del hombro izquierdo, encontrando al examen clínico inicial una masa tumoral en el cuello uterino con confirmación histológica de un carcinoma escamocelular como neoplasia primaria. Se hace diagnóstico de Carcinoma de cuello uterino estadio IVB y se inicia un tratamiento con intención paliativa con radioterapia y posterior quimioterapia sistémica. La enfermedad metastásica de origen ginecológico a nivel cutáneo confiere un mal pronóstico, con una supervivencia reportada de 1 a 37 meses después de su diagnóstico, por lo cual se deduce que la prevención y el diagnóstico temprano, particularmente en cáncer de cuello uterino, es de vital importancia en la población general.

Abstract Cervical cancer is the fourth most common cancer among gynecological neoplasms globally, representing 85% of cases in developing countries. Cutaneous metastases of gynecological origin are very rare, observed more frequently in ovarian malignancies, followed by endometrial and cervical adenocarcinoma and less frequently those of the squamous cell subtype. Currently there are about 80 case reports cited in the literature of cutaneous metastases secondary to cervical carcinoma, however, none with localization in the skin of the neck originated from a squamous cell histological subtype. In Colombia, there are no reported cases to date. We present the case of a 43-year-old patient who consulted for abdominal pain, vaginal bleeding and an extensive exophytic tumor plaque of metastatic appearance in the skin of the neck and left shoulder, finding a tumor mass in the cervix with histological confirmation of a squamous cell carcinoma as primary tumor. A diagnosis of stage IVB cervical carcinoma is made, and treatment is initiated with palliative intention with radiotherapy and subsequent systemic chemotherapy. Cutaneous metastatic disease of gynecological origin confers a poor prognosis, with a reported survival of 1 to 37 months after its diagnosis, for which prevention and early diagnosis, particularly in cervical cancer, is of vital importance in the general population.

RESUMO

O adenocarcinoma de células claras (CCA) primário de colo uterino em pacientes jovens é uma doença rara, de etiologia desconhecida e que no passado estava associada ao uso do dietilestilbestrol durante a gestação, quando sua comercialização era permitida. A queixa mais frequente do CCA é o sangramento vaginal irregular. Relatamos o caso de CCA de endocérvice em paciente jovem que engravidou naturalmente após o diagnóstico da neoplasia.(AU)

Primary cervical clear cell adenocarcinoma (CCA) in young patients is a rare disease of unknown etiology in the past associated with the use of diethylstilbestrol during pregnancy when its use was permitted. The most frequent complaint is irregular vaginal bleeding. We report the case of endocervous clear cell adenocarcinoma in a young patient who became naturally pregnant, even after the diagnosis of the neoplasia.(AU)

RESUMO

OBJECTIVE: To describe our experience with concurrent chemoradiotherapy using three-dimensional conformal radiotherapy (3D-CRT) and high-dose-rate intracavitary brachytherapy with weekly cisplatin in the treatment of patients with locally advanced cervical cancer. METHODS: Forty-three patients were identified between January 2009 and December 2015. Their medical records were retrospectively reviewed, and data on patient characteristics, tumour, treatment and toxicities were collected and analysed. RESULTS: The median age was 45 years (interquartile range (IQR): 26) The median tumour size was 45 mm (IQR: 20). Thirty-eight patients (88%) had a cervical tumour with a size of ≥ 40 mm. The median cervical tumour size evaluated by magnetic resonance imaging (MRI) was 52 mm (IQR: 17). Twenty-two patients (51%) had enlarged lymph nodes on MRI (≥ 10 mm). MRI demonstrated the involvement of the parametrium in 29 patients (67%). Fifteen patients had positive para-aortic nodes (36%). The median total treatment time was 58 days (IQR: 20). Sixteen patients (39%) received extended-field radiotherapy. Cisplatin was administered simultaneously for a median of five courses. The median follow-up period was 32 months (IQR: 28 months). Grade 3 acute toxicity was observed at the gastrointestinal level in seven patients (16%). Late grade 3/4 toxicity was observed in 14 patients (33%). Seven patients (16%) persisted with the disease and five died. The local relapse rate was 9%. Eleven patients underwent a hysterectomy after treatment. The disease-free interval was 24.2 months. The 2-year global survival rate was 82.9%. CONCLUSION: Concurrent chemo-radiotherapy appears to be an effective regimen, with acceptable toxicity, for patients with locally advanced cervical cancer.

RESUMO

Ocasionalmentes luego de una histerectomía simple, aparece un cáncer de cuello uterino (CCU) como hallazgo incidental (CIC) a la Anatomía Patológica (AP). Esta entidad, es de alto riesgo de recidiva locorregional, por lo que requiere de un tratamiento complementario. Propósito: analizar retrospectivamente los resultados de Radioterapia (RTX) complementaria en mujeres con diagnóstico de CIC referidas al Hospital Las Higueras (HH) y Centro Onco-Radiológico Regional (CORR) y compararlos con similares a comunicados en la literatura. Se analizan 29 pacientes con diagnóstico de CIC, referidos a HH y CORR entre agosto 1988 y junio 2000, tratados complementariamente con radioterapia externa y/o intracavitaria. La sobrevida actuarial a 5 años fue de 86%. El control locorregional actuarial de la totalidad de la muestra fue de 86%. En 5/29 pacientes fallecidas, todas de CCU. De las 5 fallas a tratamiento, 4 con falla locorregional. Una, con histología carcinoma indiferenciado de células pequeñas, con control locorregional y falla distante a los 175 meses. La RTX complementaria es altamente efectiva en el tratamiento de CIC.

Twenty nine patients with proven invasive cervical cancer found after simple hysterectomy were treated with complementary external and/or intracavitary Radiotherapy, 5 year actuarial survival rate of 86%. Local and regional control was achieved in 25/29, 83%. One patient presented with a complication grade 2, no treatment related deaths.
