Article Abstract
Background: Few reports discuss the outcome of pulmonary metastasis after radical esophagectomy for esophageal cancer. To clarify the data from such cases, we conducted a retrospective study on the clinical outcome of patients who developed pulmonary metastasis after undergoing radical esophagectomy.
Methods: We retrospectively reviewed the prognosis and clinical outcome of 25 patients who developed metachronous pulmonary metastasis after esophagectomy for esophageal cancer.
Results: The site of recurrence was pulmonary without extrapulmonary metastasis in 14 patients and extrapulmonary metastasis was observed in 11. Nineteen patients had multiple pulmonary metastasis and 6 had solitary pulmonary metastasis. Twenty-four of patients underwent systemic chemotherapy during initial treatment for metastatic lesions. Pulmonary metastasectomy was indicated in 5 patients with solitary metastasis. The actual 1-, 2- and 4-year survival rates were 60%, 36% and 27%, respectively. Gender, operative procedure, and postoperative morbidity were not significant prognostic factors. However, pathological staging of primary esophageal cancer was a significant prognostic factor. Survival was significantly worse in patients who did not undergo resection than in those who did. The number of pulmonary metastasis, complicated extrapulmonary metastasis and the time of recurrence were also significant prognostic factors.
Conclusions: Multiple pulmonary metastases or complicated extrapulmonary metastasis were unfavorable prognostic factors for patients with pulmonary metastasis arising from esophageal cancer. Although, surgical intervention is not recommended in such cases, metastasectomy is an acceptable choice of treatment for solitary pulmonary metastasis.

Aim: The prognostic factors and a nomogram applicable to breast cancer (BC) patients with bone metastasis (BM) who received first-line chemotherapy have not been extensively studied. This study aimed to identify prognostic factors and construct a prognostic nomogram to predict overall survival (OS) in this population.
Methods: Data for BC patients with BM undergoing first-line chemotherapy were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2016.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is a rare type of primary salivary gland-type tumor of the lung. HCCC is characterized by unique pathological features, including nests, cords, or trabeculae of clear or eosinophilic tumor cells infiltrating a mucinous or hyalinized stroma. Additional analyses of this carcinoma have revealed positive epithelial markers via immunophenotyping and gene translocation through genetic testing.

Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UTs), recently recognized as a rare malignancy described in the 5th edition of the World Health Organization Classification of Tumors, are characterized by an inactivating mutation in SMARCA4, most commonly found in the mediastinum of male smokers. Despite the aggressive nature and poor prognosis associated with these tumors, which have a median survival time of approximately 4-7 months, no standardized treatment guidelines are currently established. There are currently no reported cases of extended progression-free survival (PFS) in SMARCA4-UT patients treated with surgery and immunotherapy.

Background: ROS1, a member of the sevenless subfamily of tyrosine kinase insulin receptors, promotes tumor cell survival, proliferation, and metastasis by activating the JAK/STAT, PI3K/AKT, and MAPK/ERK pathways. It only accounts for about 2% of total NSCLC cases. No cases of acquired ROS-1 rearrangement have been reported worldwide.

Cutaneous metastasis from solid tumors is a rare manifestation that presents in the clinic. It is usually indicative of poor prognosis, with a poor response to conventional chemotherapy. The introduction of targeted therapy has changed the treatment paradigm in oncology, improving the quality of life and survival of all cancer patients.
