OBJECTIVETo review the experience of the diagnosis, surgical treatment and prognosis of metachronous second primary lung cancers.

METHODSBetween January 1983 and April 2004, 32 patients with metachronous second primary lung cancers were operated in our department. Clinical data of all these patients were reviewed retrospectively.

RESULTSThe initial procedures for their first primary lung cancers were lobectomy or pneumonectomy. Lobectomy or completion pneumonectomy for the second primary lung cancers were performed in 17 cases, limited pulmonary resection was done in 14 cases and exploration was in 1 case. The postoperative morbidity and mortality were 12% (4/32) and 3% (1/32), respectively. The 1-, 3-, and 5-year survival rate after second operation were 66% (19/29), 32% (9/28) and 19% (4/21), respectively.

CONCLUSIONSThe incidence of metachronous second primary lung cancers has been increasing gradually during recent years. The closely follow-up for patients undergoing resection for their first primary lung cancers is most important factor for improvement of the diagnosis of metachronous second primary lung cancers. Limited resection and incomplete lymph node dissection might be the factors contributing to the poor prognosis.

A case of primary malignant fibrous histiocytoma of the breast is reported. The patient was a 48-yr-old woman with a huge tumor involving almost the entire left breast. The central portion of her left breast was already rotted by extensive necrosis and inflammation. She was treated by radical mastectomy and axillary lymphadenectomy to level I. Pathologic examination supported by an immunohistochemical staining confirmed the tumor as malignant fibrous histiocytoma of giant cell type. Axillary lymph nodes were free from tumor metastasis. She had not taken any postoperative adjuvant therapy. The metastasis to lungs was found 2 months after the operation, and she died within 6 months.

Hypertrophic osteoarthropathy is characterized by clubbing of the digital tips and periosteal reaction of long bones. Most of the cases are associated with malignancy or other conditions such as congenital heart disease, liver cirrhosis, pulmonary fibrosis, biliary atresia, and gastrointestinal polyps. Hypertrophic osteoarthropathy associated with malignancy is rare in children. A few cases of hypertrophic osteoarthropathy in children with nasopharyngeal carcinoma have been reported, however, there has been no report of such case in Korea. We present a case of hypertrophic osteoarthropathy associated with nasopharyngeal carcinoma with lung metastasis in a 14-yr-old boy. In this case, hypertrophic osteoarthropathy regressed after intensive chemotherapy, but subsequently the patient died of progressive lung metastasis.

Thrombocytosis and coagulation systems activation are commonly associated with disease progression and are suggested poor prognostic factors in patients with malignancies. This study aimed to investigate the prevalence and prognostic significance of thrombocytosis and elevated fibrinogen levels in patients with advanced non-small cell lung cancer (NSCLC). Initial platelet counts and fibrinogen levels were reviewed in 854 patients with histologically proven NSCLC. Thrombocytosis was defined as platelet counts > 450 x 10(9)/L. A serum fibrinogen level > 4.5 g/L was considered high. At the time of diagnosis, initial platelet counts and serum fibrinogen levels were evaluated before treatment. Clinicopathologic data including histological type, tumor, node, metastasis (TNM) stage, performance status, treatment method, and survival time were evaluated. Initial thrombocytosis was found in 6.9% of patients, and elevated fibrinogen levels were found in 55.1% of patients. Patients with thrombocytosis had a significantly poorer prognosis than patients with normal platelet counts (P < 0.001). In multivariate survival analysis, thrombocytosis was an independent prognostic factor (P < 0.001). An elevated serum fibrinogen level was associated with poor prognosis (P < 0.001). In conclusion, initial thrombocytosis and a high fibrinogen level are independent factors for predicting poor prognosis in patients with advanced NSCLC.

Hypoxia-inducible factor-1 alpha (HIF-1α) plays a vital role in the initiation, evaluation and prognosis in lung cancer. The prognostic value of HIF-1α reported in diverse study remains disputable. Accordingly, a meta-analysis was implemented to further understand the prognostic role of HIF-1α in lung cancer. The relationship between HIF-1α and the clinicopathological characteristics and prognosis of lung cancer were investigated by a meta-analysis. PubMed and Embase were searched from their inception to January 2015 for observational studies. Fixed-effects or random-effects meta-analyses were used to calculate odds ratios and 95% confidence intervals of different comparisons. A total of 20 studies met the criteria. The results showed that HIF-1α expression in lung cancer tissues was significantly higher than that in normal lung tissues. Expression of HIF-1α in patients with squamous cell carcinoma was significantly higher than that of patients with adenocarcinomas. Similarly, non-small cell lung cancer (NSCLC) patients had higher HIF-1α expression than small cell lung cancer (SCLC) patients. Moreover, lymph node metastasized tissues had higher HIF-1α expression than non-lymph node metastasized tissues. A high level HIF-1α expression was well correlated with the expression of vascular endothelial growth factor and epidermal growth factor receptor in the NSCLC. Notably, NSCLC or SCLC patients with positive HIF-1α expression in tumor tissues had lower overall survival rate than patients with negative HIF-1α expression. It was suggested that HIF-1α expression may be a prognostic biomarker and a potential therapeutic target for lung cancer.

BACKGROUND/AIMS: Although the lung is the most common site of extrahepatic spread from hepatocellular carcinoma (HCC), the role of surgery for pulmonary metastasis remains unclear. The aim of this study was to evaluate the efficacy of pulmonary resection in patients with pulmonary metastasis from HCC. METHODS: Between July 2000 and July 2004, a total of 6 patients with pulmonary metastasis from HCC underwent curative pulmonary resections. The patients were divided into two groups (Surgery group and Non-surgery group) according to the primary treatment modality of HCC. Medical records, imaging studies, and pathologic reports of the surgical specimens were reviewed. RESULTS: Three patients in the surgery group underwent pulmonary resections for a solitary metastasis after hepatectomy for HCC, and they are all still alive. One of the 3 patients developed a tumor recurrence in the chest wall after pulmonary resection. The survival time after diagnosis of HCC were 79, 122, and 54 months, respectively. The survival time after pulmonary metastatectomy were 49, 39, and 20 months in the three patients. Another 3 patients in the non-surgery group, received a pulmonary metastatectomy; they had either a complete response HCC or partial radiologic response. These 3 patients developed recurrent disease in the liver. One of 3 patients died. The survival time after diagnosis of HCC were 153, 83, 12 months. The survival time after pulmonary metastatectomy were 51, 4, 2 months. CONCLUSIONS: The surgical resections of a solitary pulmonary metastasis from HCC in highly selected patients might be an effective treatment modalities for prolonged survival.

OBJECTIVETo study the survival and prognostic factors of stage III N2 non-small cell lung cancer (NSCLC) after surgical treatment.

METHODS266 patients with stage III N2 NSCLC underwent operation from 1982 to 1996, with the 5-year survival rate compared with those of stage N0 and N1 patients who received operation in the same period. Histological classification, number of positive nodes, location and extent of mediastinal lymph node involvement, T primary tumor status, complete or incomplete operation, the procedure of operation were univariately and multivariately analyzed to determine their impact on the 5-year survival.

RESULTSThe 5-year survival rate of patients with stage III N2 non-small lung cancer after surgical treatment was 17.3%, which was significant lower than those with N0 (51.4%) and N1 (30.4%). Four prognostic factors significantly influenced the outcome: number of positive nodes, location and extent of mediastinal lymph node involvement, T primary tumor status and complete resection of the tumor.

CONCLUSIONPatients with stage III N2 NSCLC are candidates for surgical treatment if they have evidence of limited mediastinal lymph node metastasis and prospects of complete resection.

BACKGROUND: Recently, the detectable rate of ground-glass opacity (GGO ) was significantly increased, a appropriate diagnosis before clinic treatment tends to be important for patients with GGO lesions. The aim of this study is to validate the ability of the mean computed tomography (m-CT) value to predict tumor invasiveness, and compared with other measurements such as Max CT value, GGO size, solid size of GGO and C/T ratio (consolid/tumor ratio, C/T) to find out the best measurement to predict tumor invasiveness. METHODS: A retrospective study was conducted of 129 patients who recieved lobectomy and were pathological confirmed as atypical adenomatous pyperplasia (AAH) or clinical stage Ia lung cance in our center between January 2012 and December 2013. Of those 129 patients, the number of patients of AAH, AIS, AIS and invasive adenocarcinoma were 43, 26, 17 and 43, respectively. We defined AAH and AIS as noninvasive cancer (NC), MIA and invasive adenocarcinoma were categorized as invasive cancer(IC). We used receiver operating characteristic (ROC) curve analysis to compare the ability to predict tumor invasiveness between m-CT value, consolidation/tumor ratio, tumor size and solid size of tumor. Multiple logistic regression analyses were performed to determine the independent variables for prediction of pathologic more invasive lung cancer. RESULTS: 129 patients were enrolled in our study (59 male and 70 female), the patients were a median age of (62.0±8.6) years (range, 44 to 82 years). The two groups were similar in terms of age, sex, differentiation (P>0.05). ROC curve analysis was performed to determine the appropriate cutoff value and area under the cure (AUC). The cutoff value of solid tumor size, tumor size, C/T ratio, m-CT value and Max CT value were 9.4 mm, 15.3 mm, 47.5%, -469.0 HU and -35.0 HU, respectively. The AUC of those variate were 0.89, 0.79, 0.82, 0.90, 0.85, respectively. When compared the clinical and radiologic data between two groups, we found the IC group was strongly associated with a high m-CT value, high Max CT value, high C/T ratio and large tumor size. Gender, solid tumor size, tumor size, C/T ratio, m-CT value and MaxCT value were selected factor for multivariate analysis, when using the preoperatively determined variables to predict the tumor invasiveness, revealed that tumor size, C/T ratio, m-CT value and Max CT value were independent predictive factors of IC. CONCLUSIONS The musurements of Max CT value, GGO size, solid size of GGO and C/T ratio were significantly correlated with tumor invasiveness, and the evaluation of m-CT value is most useful musurement in predicting more invasive lung cancer.

We present a recurrence prediction model using multiple clinical parameters in patients surgically treated for non-small cell lung cancer. Among 1,578 lung cancer patients who underwent complete resection, we compared the early-recurrence group with the 3-yr non-recurrence group for evaluating those factors that influence early recurrence within one year after surgery. Adenocarcinoma and squamous cell carcinoma were analyzed independently. We used multiple logistic regression analysis to identify the independent clinical predictors of recurrence and Cox's proportional hazard regression method to develop a clinical prediction model. We randomly divided our patients into the training and test subsets. The pathologic stages, tumor cell type, differentiation of tumor, neoadjuvant therapy and age were significant factors on the multivariable analysis. We constructed the model for the training set with adenocarcinoma (n=236) and squamous cell carcinoma (n=305), and we applied it to the test set with adenocarcinoma (n=110) and squamous cell carcinoma (n=154). It was predictive for the in adenocarcinoma (P<0.001) and the squamous cell carcinoma (P=0.037), respectively. Our results showed that our recurrence prediction model based on the clinical parameters could significantly predict the individual patients who were at high risk or low risk for recurrence.

BACKGROUND: Anaplastic thyroid cancer (ATC) is a rare type of thyroid malignancy and one of the most aggressive solid tumors, responsible for between 14% and 50% of the total annual mortality associated with thyroid cancer. METHODS: A retrospective study was made of all ATC cases diagnosed by biopsy in the Philippine General Hospital between 2008 and 2013. RESULTS: A total of 15 patients were identified, with a median age at diagnosis of 63 years. All tumors were at least 6 cm in size upon diagnosis. All patients had a previous history of thyroid pathology, presenting with an average duration of 11 years. Eleven patients presented with cervical lymphadenopathies, whereas seven exhibited signs of distant metastases, for which the lungs appeared to be the most common site. More than 70% of the patients presented with a rapidly growing neck mass, leading to airway obstruction. Only three patients were treated using curative surgery; the majority received palliative and supportive forms of treatment. In addition, only three patients were offered radiotherapy. Chemotherapy was not offered to any patient. Only two patients were confirmed to still be alive during the study period. The median survival time for the other patients was 3 months; in the majority of cases the patient died within the first year following diagnosis. CONCLUSION: Our experience with ATC demonstrated concordance with other institutions with respect to current clinical profile, presentation, and prognosis. An absence of distant metastases and lymph node involvement was associated with improved survival outcomes, whereas age at diagnosis and tumor size did not affect survival. Curative surgery offers the most effective means of prolonging survival. Radiotherapy and chemotherapy in combination with surgery represents a promising treatment strategy.
