Mediastinal metastasis from ovarian serous carcinoma 29 years after initial treatment

Late Recurrence of Ovarian Cancer after 18 Years of Disease-Free Survival: A Case Report and Review of the Literature

We present a case of recurrent ovarian cancer at the age of 75, gravida 1 para 0, with 18 years of disease-free survival. Chemotherapy brought a 10-month partial response status; to further improve the overall survival, the patient was evaluated using the AGO score (DESKTOP III trial, 2020), which was originally intended for cases immediately after the diagnosis of recurrence; the score has indicated a significant outcome; the patient went through a hepatosplenic metastatic site resection; and complete resection was achieved. Subsequently, the PARP inhibitor was introduced, which has led to 14 months of disease-free survival. Fifteen cases of late recurrence of epithelial ovarian cancer have been reported and are summarized at the end of this paper.

Esophageal Infiltration by High-Grade Serous Ovarian Carcinoma: A Very Rare Case Report

Introduction

Esophageal involvement in high-grade serous ovarian carcinoma is a rare phenomenon when advanced systemic disease is detected. Dysphagia is the most common guide symptom. However, diagnosis is often delayed due to its submucosal process that is not early seen in endoscopic initial evaluation, while computerized tomography (CT) scan usually shows concentric thickening of the esophageal layers and gives the suspected diagnosis.

Case Presentation

We present the case of a patient who died of mediastinitis caused by an esophageal perforated ulceration due to infiltration of high-grade serous ovarian carcinoma. In addition, this is the first case report of severe esophageal candidiasis associated that delayed diagnosis and subsequent oncological treatment.

Conclusion

Esophageal secondary infiltration must be suspected when a patient has a history of malignancy combined with consistent CT findings.

Ovarian serous carcinoma in which mediastinal recurrence of the cancer was resected 16 years after surgery: A case report

We report a rare case of ovarian carcinoma in which a mediastinal recurrence was resected 16 years after the initial operation. A 72‐year‐old woman underwent hysterectomy with adnexectomy for stage IIIC ovarian serous carcinoma after neoadjuvant chemotherapy. Six courses of adjuvant chemotherapy were administered. Three years after surgery, left supraclavicular lymph node metastasis occurred, and radiotherapy and two courses of chemotherapy were administered. Six years before presentation, a metastasis at the right cardiophrenic lymph node was resected, and six courses of chemotherapy were administered. During follow‐up, a retrosternal tumour was found. The metastatic lesion in contact with the diaphragm was thought to result from pleuroperitoneal communication, and it increased in size. Although high‐grade serous carcinoma is aggressive, its sensitivity to chemotherapy may suppress early recurrence, contributing to good outcomes, but with late recurrence. Multidisciplinary therapy including surgery is required for improved long‐term prognosis for mediastinal metastasis of ovarian serous carcinoma.

Extremely Late Recurrence of Ovarian Carcinoma Diagnosed by an Endoscopic Ultrasound-guided Fine-needle Biopsy

We herein report a case of recurrence of epithelial ovarian carcinoma 41 years after the primary surgery that was diagnosed by an endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). The differential diagnosis based on the imaging findings was difficult. We performed an EUS-FNB and compared the EUS-FNB specimen to the surgical specimen that had been resected in the primary surgery for ovarian carcinoma 41 years earlier, including immunohistochemical staining. Finally, we made a definitive diagnosis of extremely late recurrence of ovarian carcinoma of the retroperitoneum. An EUS-FNB enables an accurate histological diagnosis by obtaining a sample that is large enough to perform immunohistochemical staining.
