Purpose: Angiosarcoma is a tumor of mesenchymal origin with an extremely high rate of metastasis and invasiveness. This tumor is notorious for its very poor prognosis, although surgical excision followed by radiation therapy is considered to be effective by many. The authors experienced three angiosarcoma patients with their tumors removed and wounds covered with split-thickness skin grafts and/or latissimus dorsi free flaps. Methods: Three patients were admitted to our hospital showed plaques of different morphology. Based on their medical records, these patients were classified by sex, age, type of reconstruction, recurrence, and further treatment after surgical removal. Results: All patients were male, with a mean age of 72 years (range, 66 to 77 years). Split-thickness skin grafts with latissimus dorsi free flaps were performed on two cases, and of these two cases, cervical lymph node biopsy was done in one case, and radical neck dissection was done in the other. In all cases, radiation therapy was done within two weeks of tumor removal. Distant metastasis occurred without local recurrence in two of the cases. Lung was the first organ affected by metastasis. In the remaining case, the tumor recurred locally 6 times, and additional excision was necessary. All patients died due to local recurrence and lung metastasis. Conclusion: Irregular margins and high recurrence and metastasis rates cause a poor prognosis in large angiosarcoma of the scalp. Radiotherapy and chemotherapy should be strongly considered in large angiosarcomas.

We have experienced 5 cases of unusual well differentiated thyroid carcinoma with insular component during the past 5 years. 4 cases were presented with cervical masses but I case (patient 2.) was initiallty with lung and brain metastasis. The tumors from 4 cases showed invasive growths but that of 1 cases(patient 1.) showed intrathyroidal. Total thyroidectomy and cervical lymphnode dissection(CCND or RND) was performed in 4 cases but only RND was performed in spite of mediastinal metastasis of the tumor in patient 5 under the patient's choice. During the follow-up period, we also performed radical nephrectomy and metastatectomy for the kidney and iliac bone metastasis respectively, in patint 2. Microcsopically, the tumors showed the insular growth patterns, focally(less than 50%) in 3 cases and predominantly(more than 75%) in 2 cases. And the insular componentas were combined with papillary carcinoma in 2 cases and follicular carcinoma in 3 cases. Cervical lymphnode metastases were confirmed in 4 cases. Patient 2 died of disease with metastases to lung, brain, bone and kidney, 52 months after initial therapy. Patient 1, 3 and 4 are alive and have no recurrence and distant metastasis. Patient 5 is also alive with the mediastinal metastasis. In our experience, the well differentiated thyroid carcinomas with insular component showed characteristic histologic features, aggressive behavior in initial presentation and unfavorable prognosis regardless of the percentage of the insular component.

Primary lung cancer frequently metastasizes to distant organs. But breast is a very rare site of metastasis. So, accurate diagnosis is essential to rule out primary breast cancer. A 62-year old woman who had complained of cough was diagnosed as small cell lung carcinoma of the right lower lobe. She had a 2.5cm sized lobular mass in left upper mid portion of breast. Sonoguided breast biopsy revealed small cell carcinoma consistent with metastatis from primary lung cancer. She also had bone metastses to the scapula and the vertebrae. We report the case of metastatic breast cancer from small cell lung carcinoma.

The burden of lung cancer in terms of mortality is the highest among all types of cancers globally. The present study aimed to evaluate lifestyle related habits, clinico-pathological profile and treatment details of lung cancer patients who were registered at Malabar Cancer Centre (MCC), Kerala, during the calendar year 2010. A retrospective evaluation was made from medical records to gather data from 281 registered lung cancer cases in 241 males and 40 females, with a male to female ratio of 6.03: 1. Approximately 89% of the cases were above 50 years of age. Among males about 91% of the cases were smokers and 62% of them had a chronic smoking habit. Adenocarcinomas, squamous cell carcinomas, non-small cell carcinomas and small cell cancers accounted for 10.7, 13.9, 17.0 and 5.7% respectively. Out of 281 cases around 67% were diagnosed with distant metastasis and the remainder had regional lymph node involvement. However, no statistically significant difference was observed for secondary site of tumor according to gender. As majority of the cases reported at MCC were in an advanced stage of the disease, histology of the secondary site from supraclavicular lymph nodes or liver was taken for diagnosis. Initiation of population based screening for early detection of cancer, and primary and secondary prevention strategies for reducing the prevalence of tobacco consumption are high priorities to reduce the lung cancer burden in Kerala.

Sarcomatoid carcinomas of the lung are rare malignant biphasic tumors, which contain both a malignant epithelial component and a sarcomatoid component. The majority of patients are men and the mean age of onset is 60 years at the time of diagnosis. A metastasis to the regional lymph nodes and to distant organs is common. The clinical course of patients with this neoplasm is aggressive, with an overall 5-year survival rate approximating 20%. A sarcomatoid carcinoma of the lung is often observed in the large bronchi and peripheral lung field than in the trachea, and the clinical manifestations are related to their specific location. We report a case of sarcomatoid carcinoma of the lung in a 79-year-old man who presented with dyspnea on exertion.

Biological behavior and treatment results of 33 patients with Adenoid Cystic Carcinoma (ACC) in the Head and Neck at Yonsei Cancer Confer for 10 years between 1971 and 1980 were retrospectively analysed. Most common, primary site was minor salivary glands such as maxillary sinus, nasal cavity and base of tongue. The typical biological behavior of these tumors was very slowly in growth with long time of duration(mean 19 months) from 1 month to 10 years and more frequent of nerve invasion but rare invasion of neck nodes. Local control and failure pattern in the results of treatment, 16 of 17 patients with irradiation alone were seen complete or partial response but 5 cases of locoregional recurrence, 2 cases of failure of neck node and 4 cases of distant metastasis as lung and brain. On the other hand, among 10 cases of surgery and postoperative irradiation, 2 cases of locoregional failure and 3 cases of distant metastasis as lung and bone. 2 of 4 cases with surgery alone were recurred within primary site. Actuarial overall NED survival at 3 ana 10 years were $52.6\%$ and $42.8\%$, respectively. Survival rate of 10 Patients with surgery and Postoperative irradiation was more high than 17 Patients of radiation alone. Therefore, we have known that surgery with postoperative adjunctive irradiation is most effective treatment modality of adenoid cystic carcinoma in the head and neck. Primary site, treatment modality and with or without nerve ana bone invasion have influenced on prognosis.

Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy. To rule out the presence of metastasis to lymph nodes or distant organs, patients should undergo meticulous clinical staging. Assessing patients' functional status is required to ensure that there are no medical contraindications, such as impaired pulmonary function or cardiac comorbidities. Although various combinations of the number, size, and location of ports are available, finding the best method of port placement for each surgeon is fundamental to maximize the efficiency of the surgical procedure. When conducting VATS lobectomy, it is always necessary to comply with the following oncological principles: (1) the vessels and bronchus of the target lobe should be individually divided, (2) systematic lymph node dissection is mandatory, and (3) touching the lymph node itself and rupturing the capsule of the lymph node should be minimized. Most surgeons conduct the procedure in the following sequence: (1) dissection along the hilar structure, (2) fissure division, (3) perivascular and peribronchial dissection, (4) individual division of the vessels and bronchus, (5) specimen retrieval, and (6) mediastinal lymph node dissection. Surgeons should obtain experience in enhancing the exposure of the dissection target and facilitating dissection. This review article provides the basic principles of the surgical techniques and practical maneuvers for performing VATS lobectomy easily, safely, and efficiently.

Background: In malignancies, detection of metastatic foci is of value in making therapeutic plans for treatment of disease and prevention of life-threatening complications. Common sites for metastasis of bronchogenic cancer include lymph nodes, liver, brain, adrenals and bone. Skull, vertebrae, ribs and long bones are common sites for bone metastasis. But in epidermoid carcinoma, the incidence of bone metastasis is relatively low and especially to the distal phalangeal bone is rare. Methods: We experienced a case of epidermoid carcinoma with the first distant metastasis to the fifth distal phalangeal bone, right toe. Results: The initial stage in the diagnosis of epidermoid carcinoma was T4N3MO. During the third round of anticancer chemotherapy, we recognized the distant metastasis to the fifth distal phalangeal bone for the first time. Localized abnormal findings were noted by bone X-ray and scanning. By a histopathologic examination of the amputated toe, we confirmed the metastasis of epidrmoid bronchogenic carcinoma. Conclusion: If localized abnormal finding is discovered at an unusual site for metastasis, we recommend physicians to consider the possibility of metastasis even though it is very low.

Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

Adeonoid cystic carcinoma (ACC) is one of the most common malignant tumors of salivary glands. It is characterized by a relentless regrowth especially around nerve tissues and a high rate of hematogenous distant metastasis. Clinically most deaths from salivary ACC are caused by delayed lung metastases that are resistant to conventional chemotherapy. So, knowledge of cellular and molecular properties that influence the dissemination of metastatic tumor cells, is important for new treatment strategies of metastatic lesions. We determined expressions of angiogenic signaling molecules microvessel density (MVD) using surgical specimens of human salivary ACC. Protein expressions of vascular endothelial growth factor (VEGF), VEGF receptor (VEGFR)-2, activated VEGFR-2, and human CD31 were assessed in 20 cases of salivary ACC by immunohistochemical staining. Most of the tumors, especially ACC with a tubulocribriform pattern, were positive for antibodies of VEGF, VEGFR-2, and activated VEGFR-2. The overall percentages of the 20 specimens expressing VEGF, VEGFR-2, activated VEGFR-2 were 90, 95, and 95%, respectively. Immunoreactivities of the biomarkers in salivary ACC were higher than those in normal salivary gland. Furthermore, immune-related cells as well as tumor cells expressed VEGF/VEGFR-2. Microvessel density of salivary ACC was higher than that of normal salivary gland (P<0.05). Taken together, angiogenic signaling molecules are actively expressed in salivary ACC. And we suggest that these molecules may have critical role in the hematogenous spread of salivay ACC, which has a propensity for delayed lung metastasis. Therefore, these biomarkers can be molecular targets for therapy of metastasis of salivary ACC.
