[Heparin-induced thrombocytopenia developed during the acute phase after left upper lobectomy for lung cancer].

Heparin-induced thrombocytopenia (HIT) is a serious adverse effect of heparin administration. This must not be rarely encountered but is not often reported in Japan compared to Western countries. A 68-year-old woman underwent left upper lobectomy for lung cancer.

[Primary malignant peripheral nerve sheath tumor of the lung; report of a case].

We report a patient with primary malignant peripheral nerve sheath tumor (MPNST) of the lung. A 84-year-old man was referred to our hospital because of an abnormal shadow on chest X-ray. The computed tomography( CT) of the chest revealed a 6 cm tumor close to the posterior chest wall in the left thorax.

[The influence of difference of surgical procedure for the young spontaneous pneumothorax to the recurrence rate after surgery].

Introduction: In spontaneous pneumothorax (SP) in patients under the age of 30, we studied the postoperative recurrence rate due to differences in the surgical procedures and the patient's age.

Materials And Methods: Between October 2003 and September 2012, 351 operations were performed for the young(30 years or younger)SP in our hospital. The recurrence rate was calculated in 2 age groups( under 20 or older) with different surgical procedures which were classified into 5 groups on the basis of the combination of the covering site with the polyglycol acid (PGA) seat and the presence or absence of ligation at both ends of staple-line.

[Treament using a free omental flap for pulmonary Aspergillosis with chronic methicillin-resistant Staphylococcus aureus( MRSA) empyema after fenestration].

A case is 48-year-old man who had a history of Blalock-Taussig shunt and the radical operation for Fallot's tetralogy, had been performed cavernostomy and fenestration operation for aspergilloma of left upper lobe in the previous hospital due to control blood spitting. Although the contents of the abscess cavity were removed, the opened cavity was again infected by methicillin-resistant Staphylococcus aureus (MRSA) and he was referred to our hospital. The plombage of free omental flap with vascular anastomosis was performed.

[Re-operation for recurrent pulmonary metastases].

Fifty two patients with metastatic lung tumors were treated surgically in our hospital. Second pulmonary resections were performed in 6 patients. They consist of 1 male and 5 females, their age ranged from 59 to 80 years old( average 66 years old).

[Mixed squamous and glandular papilloma].

The patient was a 64-year-old man. He had a smoking history for 43 years (20 cigarettes per day). Being pointed out a mass shadow in the left lower lung field on chest X-ray in a regular checkup, he was referred to our hospital.

[Examination using multivariate analysis of the risk factors by surgical approach in elderly intractable pneumothorax].

Purpose: In this study, we evaluated the risk factors for postoperative complications in elderly patients with intractable pneumothorax and constructed a risk assessment model.

Materials And Methods: Between January 2004 and December 2011, 83 elderly patients( age, 75 years or older) underwent an operation at our hospital for intractable pneumothorax. Preoperative factors of these cases were assessed to clarify which is contributory to the development of postoperative complications by using univariate analysis and multivariate logistic regression analysis.

Effect of postoperative adjuvant chemotherapy with tegafur-uracil on survival in patients with stage IA non-small cell lung cancer: an exploratory analysis from a meta-analysis of six randomized controlled trials.

Background: The Seventh Edition of the Tumor, Node, Metastasis Classification of Malignant Tumors in non-small cell lung cancer (NSCLC) proposes a more detailed classification of primary tumor diameter. Stage IA T1 disease is subdivided into two groups: T1a disease (tumor diameter, < or = 2 cm) and T1b disease (tumor diameter, >2 to < or = 3 cm). Tegafur-uracil (UFT) improves survival in patients with stage I NSCLC.

Four years experience of the survey on quality control of lung cancer screening system in Japan.

Although quality control is essential in mass screening system for early detection of cancer, no global method for quality control has not been established, because the mass screening system in each country is quite different from each other. At present, we have to find appropriate method for each cancer and for each country. In 2000, The Lung Cancer Screening Division (LCSD) of the Miyagi Prefectural Committee for Management of the Cancer Screening System (Miyagi PCMCSS) decided to evaluate annually whether the local governments had appropriate information to evaluate the quality of lung cancer screening systems, announcing that the results would be informed to residents.

Meta-analysis of postoperative adjuvant chemotherapy with tegafur-uracil in non-small-cell lung cancer.

Purpose: Recent clinical trials have shown the efficacy of platinum-based adjuvant chemotherapy for completely resected non-small-cell lung cancer (NSCLC). In Japan, many clinical trials of adjuvant chemotherapy with tegafur-uracil (UFT) have been conducted, and some trials showed positive results while others showed negative results. Thus, we performed a meta-analysis to assess the efficacy of postoperative adjuvant chemotherapy with UFT in NSCLC.

Surgical treatment of stage I non-small cell lung carcinoma.

In stage I non-small cell lung cancer (NSCLC), the cancer is localized to the lung. For this early stage NSCLC, therefore, surgery is considered to be the treatment of choice. In this report, we reviewed the surgical treatment approaches for stage I NSCLC, placing emphasis on limited resection and video-assisted thoracic surgery (VATS).

The efficacy of lung cancer screening conducted in 1990s: four case-control studies in Japan.

The efficacy of lung cancer screening is still controversial. In order to evaluate efficacy of mass screening for lung cancer in 1990s, the Japanese Ministry of Health and Welfare planned to conduct four independent case-control studies in four different regions; Miyagi, Gunma, Niigata, and Okayama Prefecture. The study design of all the four studies was a matched case-control study in which the decedents from lung cancer were defined as cases.

A randomized trial of postoperative UFT therapy in p stage I, II non-small cell lung cancer: North-east Japan Study Group for Lung Cancer Surgery.

Objective: A prospective randomized trial was performed to investigate the prognostic advantage of postoperative adjuvant chemotherapy in patients with resected stage I-II non-small cell lung cancer (NSCLC).

Patients And Methods: From March 1992 to December 1994, 221 patients with completely resected stage I-II primary NSCLC were enrolled and randomly assigned to two groups, as follows: 2-year oral administration of Uracil plus Tegafur (UFT) (adjuvant group, 109 patients), and surgical treatment alone (control group, 110 patients).

Results: The overall 5-year survival rates were 79% for the adjuvant group and 75% for the control group, and there was no statistical significance.

Preoperative estimation of pulmonary extravascular thermal volume in patients undergoing pneumonectomy.

Pulmonary extravascular thermal volume (PETV) was measured during pulmonary artery occlusion in 18 patients preoperatively and 7 patients postoperatively who were undergoing pneumonectomy. We found that the PETV decreased from 6.6±2.
