cervical carcinoma

BACKGROUND: Mixed medullary and follicular cell-derived thyroid carcinoma (MMFCC) is characterized by the coexistence of follicular and C cell-derived tumour cell populations within the same lesion. Due to its rarity, its etiology and clinical course remain unclear, and treatment for advanced or recurrent cases has not been established. CASE PRESENTATION: We report a case of MMFCC treated with selpercatinib. The patient was a 69-year-old male presenting with tumors in the right thyroid lobe and in the upper mediastinum...

Clear cell carcinoma is a rare and very aggressive subset of cervical cancer, with poor outcome if diagnosed at advanced stage. There are few data available on the optimal management of this histotype, and treatment recommendations that include surgery and chemoradiotherapy, are essentially based on those for squamous cell carcinoma. Here we report the case of a young patient newly diagnosed with advanced stage (FIGO IIB) clear cell carcinoma of the uterine cervix who received a window of opportunity one injection of nivolumab followed by standard chemoradiotherapy...

•Cervical cancer plays a large role in morbidity and mortality for gynecologic cancer.•Most cases are involved with high-risk HPV, rare cases of low-risk HPV associated cancer exists.•Low risk HPV associated cervical cancers have increased difficulty in diagnosis.•No distinction exists in treatment between low and high risk HPV associated cervical cancer.

INTRODUCTION: Vaginal cancer is a rare gynecologic malignancy. While in a localized disease, concurrent chemoradiation grants local control and better overall survival, in a metastatic setting, the management options are very limited. Furthermore, recurrent cervical, vulvar, and vaginal carcinomas notoriously develop resistance to treatment, and consequently, their prognosis is still poor. CASE PRESENTATION: We herein present the case of a woman with a nodal relapse of vaginal carcinoma, effectively treated with third-line immunotherapy...

Gastric adenocarcinoma (GAS) is a rare subtype of mucinous adenocarcinoma characterized by gastric differentiation and is unrelated to human papillomavirus (HPV) infection. This report discusses a 40-year-old female who presented with abdominal distension accompanied by increased abdominal circumference. CT of the abdomen and pelvis showed a large 21.0*12.7*26.0 cm mass later diagnosed as GAS combined with squamous cell carcinoma on surgical pathology. Immunohistological staining of GAS was positive for CK7, MUC6, PAX-8 CEA, and P53 (wild type) and negative for CDX2, CK20, ER, PR, P16, and WT1...

OBJECTIVE: Metastatic spinal tumors represent a rare but concerning complication of primary thyroid carcinoma. We identified demographics, metastatic features, outcomes, and treatment strategies for these tumors in our institutional cohort. MATERIALS AND METHODS: We retrospectively reviewed patients surgically treated for spinal metastases of primary thyroid carcinoma. Demographics, tumor characteristics, and treatment modalities were collected. The functional outcomes were quantified using Nurik, Modified Rankin, and Karnofsky Scores...

BACKGROUND: Cervical cancer remains a leading cause of death, particularly in developing countries. WHO screening guidelines recommend human papilloma virus (HPV) detection as a means to identify women at risk of developing cervical cancer. While HPV testing identifies those at risk, it does not specifically distinguish individuals with neoplasia. We investigated whether a quantitative molecular test that measures methylated DNA markers could identify high-risk lesions in the cervix with accuracy...

Leiomyoma is the most prevalent benign tumor of the female reproductive system. Benign metastasizing leiomyoma (BML) is a rare phenomenon that presents at distant sites, typically the lungs, exhibiting histopathological features similar to the primary uterine tumor in the absence of malignancy features in both. Fumarate hydratase-deficient uterine leiomyoma (FH-d UL) is an uncommon subtype among uterine smooth muscle tumors (0.5-2%), showing distinctive histomorphology and FH inactivation. The majority of FH-d ULs are sporadic, caused by somatic FH inactivation, while a minority of cases occur in the context of the hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome caused by germline FH inactivation...

OBJECTIVE: To analyze the potential factors influencing new-onset postoperative transient vocal cord paralysis (VCP) in thyroid cancer patients. METHODS: Case information of 8,340 thyroid cancer patients hospitalized at XX from January 2018 to December 2020 was collected retrospectively and analyzed. The possible influencing factors were analyzed using a chi-square test, rank-sum test, and multiple logistic regression analysis. A nomogram was used to construct the clinical prediction model that was validated in the validation set by ROC, calibration curves, and DCA...

OBJECTIVE: Keratin 15 (KRT15) exhibits inconsistent prognostic roles in different cancers, and its prognostic value in early cervical cancer patients who receive tumor resection remains unknown. This study aimed to assess the relationship of KRT15 expression with prognosis in these patients. METHODS: Totally, 147 early cervical cancer patients who received tumor resection were reviewed in this retrospective study. KRT15 was detected in formalin-fixed paraffin-embedded tumor tissue by immunohistochemistry (IHC)...

Parathyroid carcinoma (PC) is a rare endocrine neoplasm that typically presents with osteopenia/osteoporosis, nephrolithiasis, asthenia, and neuropsychiatric symptoms. We describe the case of a 48-year-old woman, presenting with a large painful hematoma in the cervicomediastinal area. The neck ultrasound (US) demonstrated a solid lesion measuring 40 × 80 × 55 mm, markedly hypoechoic, which extended from the right thyroid lobe to the mediastinum. The blood tests showed elevated serum calcium and parathyroid hormone (PTH) concentrations, consistent with hypercalcemic primary hyperparathyroidism...

BACKGROUND: Image-guided adaptive brachytherapy (IGABT) demonstrates an excellent local control rate and low toxicity while treating cervical cancer. For intracavitary/interstitial (IC/IS) brachytherapy (BT), several applicators are commercially available. Venezia (Elekta, Sweden), an advanced gynecological applicator, is designed for IC/IS BT for treating locally advanced cervical cancer. There are two types of interstitial needles for the Venezia applicator: the round needle and sharp needle...

BACKGROUND: The cervix is the lower portion of the uterus, which connects this organ to the vagina through the endocervical canal. OBJECTIVE: This study aimed to determine the histopathologic patterns and factors associated with cervical lesions at Jimma Medical Center from September 12, 2017, to September 12, 2019. METHODS: A 2-year facility-based cross-sectional study was conducted from May 1 to June 30, 2020. RESULT: In this study, cervical cancer was the most common (71%) cause of cervical lesions...

OBJECTIVE: Contrast-enhanced ultrasound (CEUS) and elastography are of great value in the diagnosis of cervical cancer (CC). However, there is limited research on the role of contrast-enhanced ultrasound combined with elastography in predicting concurrent chemoradiotherapy and disease progression for cervical cancer. The purpose of this study was to evaluate the feasibility of contrast-enhanced ultrasound combined with elastography and tumor prognosis. METHODS: MRI was performed on 98 patients with cervical cancer before and after treatment...

OBJECTIVE: To evaluate the impact of the different types of neoplasms and lineages on mortality of patients with SLE. METHODS: Retrospective and observational comparison of the neoplasm-related deaths in patients with SLE and the general Spanish population reported in the Spanish Hospital Discharge Database. To determine the impact of SLE on the risk of dying from each neoplasm lineage, a binary logistic regression considering age, female sex, tobacco and alcohol consumption, was performed...

BACKGROUND: Diagnosing atypical glandular cells (AGC) is a significant challenge in cytomorphology. METHODS: A retrospective study was undertaken to assess the prevalence of AGC and the subsequent histological outcomes over 5 years at a single institution. RESULTS: A total of 159,649 ThinPrep Pap tests, including 395 cases of AGC, were retrieved, of which 330 AGC cases had follow-up histopathology. Among these 330 cases, 43.9% were classified as AGC not otherwise specified, followed by AGC-endocervical cells at 33...

PROCEDURES: This prospective study included patients with NPC who underwent [68  Ga]pentixafor PET/CT and 2-[18 F]fuoro-2-deoxy-D-glucose ([18 F]FDG) PET/CT within one week between November 2022 and March 2023. The [68  Ga]pentixafor and [18 F]FDG uptakes in primary and metastatic lesions were measured and compared...

High-grade neuroendocrine cervical cancers (NETc) are exceedingly rare, highly aggressive tumors. We analyzed 64 NETc tumor samples by whole-exome sequencing (WES). Human papillomavirus DNA was detected in 65.6% (42/64) of the tumors. Recurrent mutations were identified in PIK3CA, KMT2D/MLL2, K-RAS, ARID1A, NOTCH2, and RPL10. The top mutated genes included RB1, ARID1A, PTEN, KMT2D / MLL2, and WDFY3, a gene not yet implicated in NETc. Somatic CNV analysis identified two copy number gains (3q27.1 and 19q13.12) and five copy number losses (1p36...
