Background: We reviewed the clinical outcomes of patients with oligometastatic (OM) non-small cell lung cancer (NSCLC) who received multimodal therapy including lung surgery. Methods: We retrospectively analyzed 117 patients with OM NSCLC who underwent complete resection of the primary tumor from 2014 to 2017. Results: The median follow-up duration was 2.91 years (95% confidence interval, 1.48-5.84 years). The patients included 73 men (62.4%), and 76 patients (64.9%) were under the age of 65 years. Based on histology, 97 adenocarcinomas and 14 squamous cell carcinomas were included. Biomarker analysis revealed that 53 patients tested positive for epidermal growth factor receptor, anaplastic lymphoma kinase, or ROS1 mutations, while 36 patients tested negative. Metastases were detected in the brain in 74 patients, the adrenal glands in 12 patients, bone in 5 patients, vertebrae in 4 patients, and other locations in 12 patients. Radiation therapy for organ metastasis was performed in 81 patients and surgical resection in 27 patients. The 1-year overall survival (OS) rate in these patients was 82.8%, and the 3- and 5-year OS rates were 52.6% and 37.2%, respectively. Patients with positive biomarker test results had 1-, 3-, and 5-year OS rates of 98%, 64%, and 42.7%, respectively. These patients had better OS than those with negative biomarker test results (p=0.031). Patients aged ≤65 years and those with pT1-2 cancers also showed better survival (both p=0.008). Conclusion: Surgical resection of primary lung cancer is a viable treatment option for selected patients with OM NSCLC in the context of multimodal therapy.

Metastatic tumors to the jaw bones are uncommon. The most common metastatic tumors to the jaw bones are the breast, lung and kidney. In the jaw bones, the common location of the lesions is the mandible, and the posterior area of the mandible is more commonly affected. The radiographic appearance is quite variable. In this report, a very rare case of metastatic gastric adenocarcinoma to the mandible is presented. The patient had undergone a gastrectomy 3 years ago.

Primary rib tumors occur in dogs at a much lower frequency than appendicular bone neoplasms. A 3-year-old 3.5kg female maltese was referred to the Veterinary Medical Teaching Hospital because of a 2-month history of severe coughing and a 1-month history of dyspnea, gaging, and anorexia. The plain thoracic radiography revealed a huge well-defined mass in the left thoracic cavity, and a diagnosis of primary rib chondrosarcoma was established by histopathologic evaluation of the surgical biopsy specimen. At operation, a 8-x12-x4.5-cm relatively large firm mass was found filling the lumen of the thoracic, which was diffusely attached to the left 2-9th rib. This mass oppressed the heart, left lung and diaphragm.

Swyer-James syndrome is a rare disease with patients presenting with unilateral hyperlucent lungs and hypoperfusion due to hypoplasia of the pulmonary artery and bronchiolitis obliterans. A unilateral hyperlucent lung generally develops after a lower respiratory tract infection during early childhood. In extremely rare cases, an association of bronchogenic carcinoma with Swyer-James syndrome has been reported. We report a case of bronchogenic squamous cell carcinoma associated with Swyer-James syndrome that performed right upper lobectomy and lymph node dissection with a relevant literature review.

Primary pulmonary angiosarcomas are extremely rare tumors. The diagnosis is often delayed due to nonspecific symptoms, mimicking pulmonary embolism and require careful clinical evaluation to exclude metastasis from the heart, pericardium, and distant extrathoracic sites. Most diagnosis are made postmortem. We report a case of primary pulmonary angiosarcoma histopathologically confirmed postoperatively, which was clinically suspected endobronchial carcinoma with endobronchial obstruction with relavant literature review.

We report a rare case of a 38-year-old woman with a bronchial carcinoid tumor arising from an intralobar bronchopulmonary sequestration. The vascular supply to the sequestered left lower lobe originated from the descending thoracic aorta. A left lower lobe lobectomy was performed. The findings of the pathological examination revealed an atypical carcinoid tumor that was immunopositive for chromogranin and synaptophysin. At the 3-year follow-up examination, the patient was healthy.

Tumors that metastasize to the pituitary gland are unusual, and are typically seen in elderly patients with diffuse malignant disease. The most common metastases to the pituitary are from primary breast and lung cancers. We report a 65-year-old woman with pituitary metastasis from breast cancer who presented with recent-onset left progressive deterioration of visual acuity and visual field. The clinical diagnosis was made after brain and sellar magnetic resonance imaging showed a large sellar mass compressing the optic chiasm and invading the pituitary stalk. An otorhinolaryngology and neurosurgery team removed the tumor via a transsphenoidal approach, and this procedure obtained symptomatic relief. Postoperatively, metastasis from breast invasive ductal adenocarcinoma was confirmed histologically. We report this unusual case with a review of the relevant literature.

Primary malignant melanoma of the mediastinum is extremely rare : To date, there have been only 8 cases reported in the literature. We report a case of a 50-year-old woman presented with an anterior mediastinal mass. The mass invaded the lung parenchyme of right upper lobe, which was wedge-resected with the mass. Microscopically, spindle or polygonal tumor cells with prominent nucleoli and intracytoplasmic melanin pigments are characterized and Fontana stain confirmed the presence of melanin pigment. Immunohistochemical studies showed diffuse positive staining for HMB45, S100 protein and vimentin, which further suggested melanoma.

Hemangiopericytoma is a rare vascular tumor derived from the pericyte and usually occures in the lower extremities and the retroperitoneum. Complete excision is treatment of choice. Regular follow up is strongly recommended due to its potential malignancy which is recurrence and metastasis. We experienced surgical excision of metastatic pulmonary hemangiopericytoma from retroperitoneal hemangiopericytoma completely excised 10 years ago.

The Wiskott-Aldrich Syndrome Protein family Verprolin - homologous proteins (WAVEs), encoded by a metastasis promoter gene, play considerable roles in adhesion of immune cells, cell proliferation, migration and destruction of foreign agents by reactive oxygen species. These diverse functions have lead to the hypothesis that WAVE proteins have multi-functional roles in regulating cancer invasiveness, metastasis, development of tumor vasculature and angiogenesis. Differentials in expression of WAVE proteins are associated with a number of neoplasms include colorectal cancer, hepatocellular cancer, lung squamous cell carcinoma, human breast adenocarcinoma and prostate cancer. In this review we attempt to unify our knowledge regarding WAVE proteins, focusing on their potentials as diagnostic markers and molecular targets for cancer therapy.
