Ovarian cancer with intrathoracic metastases is often accompanied by abdominal-related symptoms, and ovarian cancer cases with only thoracic lesions

چکیده
Thoracoscopy is a useful method for diagnosing plural lesions. We diagnosed 3 cases of ovarian adenocarcinoma by thoracoscopy. All patients were middle-aged and elderly women. Initial examination revealed intrathoracic lesions including pleural effusion, but intraperitoneal lesions were unclear. In all cases, adequate samples of tumor cells obtained using thoracoscopy were used in the identification of tumor origin. Elevated serum levels of cancer antigen 125 (CA-125) and Krebs von den lungen-6 (KL-6) were observed in 2 of the 3 patients. Diagnoses of ovarian cancer were based on immunohistochemical examinations and clinical course. This report describes the diagnostic usefulness of thoracoscopy and serum KL-6 in cases of ovarian cancer with predominantly intrathoracic lesions.

Evaluation of calcified metastatic lesions by conventional imaging can be challenging. Ovarian cancer metastases can present with calcification which might increase in size and number following therapy. It is not entirely clear whether these calcifications are associated with tumor response or disease progression. Calcified lesions which do not change in size or configuration are particularly p...

Introduction: Ovarian serous carcinoma is an aggressive malignancy, often with metastases at presentation. Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy has been studied as a treatment option for intraperitoneal spread of ovarian cancer. Hyperthermic intrathoracic chemotherapy, the thoracic counterpart to hyperthermic intraperitoneal chemotherapy, is emerging as ...

Background: Transitional cell carcinoma (TCC) is a rare type of ovarian epithelial cancer. This type of ovarian cancer accounts for only 1% of superficial epithelial carcinomas. Ovarian cancer is a major clinical challenge in obstetrics and gynecology. The reason of this is the lack of specific symptoms for ovarian cancer before the recurrence and progression of the tumor, so many cases are not...
