ObjectiveTo summarize the experiences and lessons of diagnosis and treatment of follicular thyroid carcinoma (FTC) with lymph node and lung metastases.MethodThe clinicopathologic data of a case of FTC with metastases of cervical, mediastinum, axillary lymph nodes, and bilateral lungs were analyzed retrospectively.ResultsThe case was a 39 years old male patient, who was diagnosed with the right FTC with multiple metastases. The total thyroidectomy+lymph node dissection in bilateral central and bilateral neck regions+lymph node dissection in the left axillary was intended to perform in the Department of Thyroid and Parathyroid Surgery of the West China Hospital. During the operation, the upper mediastinal lymph node fusion was found, and the tumor was tightly adhered with the recurrent laryngeal nerve, the signal was lost after the adhesion separation. In the right central area, the enlarged lymph nodes penetrated down into the upper mediastinum. More enlarged lymph nodes extended upward into the subclavian area in the left armpit. Considering a longer operation time and about 2 000 mL bleeding amount, the mediastinal and left neck operation was decided to perform in the second stage after consulting with the thoracic surgeon. At more than 6 months after the operation, the patient underwent the mediastinal lymph node dissection+superior vena cava (SVC) restoration+metastatic tumor resection+SVC shunt operation in the Department of Thoracic Surgery of the West China Hospital. The operation was successful, without hypocalcemia, dyspnea, and other complications. At 8 months after the operation, the third operation was performed in the Department of Thyroid and Parathyroid Surgery of the West China Hospital, that was, total residual thyroidectomy+left central and left cervical lymph node dissection+left axillary lymph node dissection (level Ⅱ–Ⅲ). The postoperative pronounce didn’t change, without hypocalcemia and other complications. Three times of iodine ablation therapy were performed in the West China Hospital. The occupy didn’t be found by the neck ultrasound and the pulmonary metastasis was stable by the CT during the regular follow-up.ConclusionsAccording to this case, neck surgery with SVC syndrome, SVC syndrome should be treated preferentially. For patient with complicated condition, unconventional approaches could be selected according to actual condition of patient, and staging surgery might be a good choice.
As the most common primary malignant bone tumor in children and adolescents, osteosarcoma has the characteristics of high malignancy, easy metastasis and poor prognosis. The recurrence, metastasis and multi-drug resistance of osteosarcoma are the main problems that limit the therapeutic effect and survival rate of osteosarcoma. Among them, lung metastasis is often the main target organ for distant metastasis of osteosarcoma. In recent years, people have paid attention to the signaling pathway of the occurrence and development of osteosarcoma and made in-depth studies on its mechanism. A variety of relevant signaling pathways have been constantly clarified. At present, there is still a lack of systematic and multi-directional exploration and summary on the signaling pathway related to the pulmonary metastasis of osteosarcoma. This paper explores the new direction of targeted therapy for osteosarcoma by elucidating the relationship between the signaling pathway associated with osteosarcoma and the pulmonary metastasis of osteosarcoma.
We reported a 32 years female patient in whom lung metastasis from breast cancer was presented as solitary pulmonary pure ground-glass opacity (GGO) lesion. The patient received rational preoperative examinations and surgery though the preoperative diagnosis was not accurate. Because of different therapy strategies and purposes, it is crucial to make distinction of atypical metastases from primary cancers. Thus, for patients with a history of malignancy, possible metastasis should be taken into consideration if new GGO was found on the CT. Besides this, the follow-up interval of CT should be shortened appropriately, preoperative examinations and surgical procedures should be made according to the suggestions of multidisciplinary team.
