Background: Pancreatic cancer is a highly aggressive solid tumor. Patients with metastases from pancreatic cancer have poor survival rates. Here, we report the outcomes of 6 patients for whom resection of lung metastases was performed after a pancreatectomy to treat pancreatic cancer. Methods: We retrospectively reviewed the perioperative clinical data of patients with lung metastases resulting from primary pancreatic cancer who were treated with lung resection between 2008 and 2015. We report 6 cases where lung resection was performed to treat lung metastases after a pancreatectomy. Results: The number of lung metastases was 1 in 5 cases and 2 in 1 case. The surgical procedures performed to treat the lung metastases included 4 wedge resections and 2 lobectomies. The cell type of the primary tumor and metastases was tubular adenocarcinoma in 5 cases and intraductal papillary-mucinous carcinoma in 1 case. All 6 patients survived with a mean follow-up period of 65.6 months, although the disease recurred in 2 patients. Conclusion: Resection of lung metastases resulting from primary pancreatic cancer may lengthen survival, provided the patient can tolerate surgery.

Most clinicians have taken a lot of interest in tumors arising from the bony thorax because not only of their rarity and predictable diagnosis which could be reflected as a unique radiologic shadow but also variable surgical modes for maintenance of chest wall stability encountered after en-bloc resection. By the retrospective review, we have analyzed 24 cases of primary bony thorax tumors which were experienced and surgically treated at the St. Mary`s hospital of Catholic Medical College from Jan. 1969 to Sept. 1984. The results are as follows: 1. Age incidence was evenly distributed through all decades and the male-female ratio is 15:9. 2. 16 cases out of 24 were benign tumors and the commonest one of which was fibrous dysplasia. 3. Remaining 8 cases were malignant tumors and among which osteogenic sarcoma was the commonest one. 4. The majority of tumors [22/24] were developed from the rib and the remains were from the sternum. 5. Common manifestation were palpable mass or swelling and localized tenderness. 6. Various kinds of operative procedure were underwent: single resection of rib including tumor,14 cases; multiple resection of ribs with chemotherapy or myoplasty, 2 cases; en-bloc resection of the chest wall and reconstructive procedure, 5 cases; partial resection of sternum, 1 case; bone biopsy and chemotherapy, 2 cases.

Tracheal neurilemoma, an extremely rare benign tracheal tumor that there has been only one case reported in 1996 throughout the nation, is a slowly progressing disease that obliterates the upper airway, delays diagnosis for its symptom similarity to asthma, and makes intubation for operation difficult. Bronchoscopic is therefore needed for diagnosis. There are two options for the treatment methods, a bronchoscopic resection or open surgical resection; however if intubation is difficult, then the bronchoscopic resection is used first to keep the airway open for the surgical resection. In this case, the severe tracheal stenosis impeding intubation made the surgical resection of the primary tracheal neurilemoma with extratracheal mass impossible; therefore, bronchoscopic laser resection was applied first to optain the airway passage for endotracheal intubation, followed by a successful open surgical resection.

Objective : We investigated the effect of hypnotics on sleep quality, cognitive function, and depressive mood in patients with insomnia following brain tumor resection. Methods : From patients who underwent brain tumor resection, we recruited 10 patients with insomnia who received hypnotics for more than 1 week during a 3-week follow-up period (insomnia group). We also recruited 12 control patients with brain tumors but without insomnia (control group). We evaluated sleep quality at baseline and 3 weeks later using the Insomnia Severity Index (ISI), the Pittsburgh Sleep Quality Index (PSQI), the Stanford Sleepiness Scale (SSS), and the Epworth Sleepiness Scale (ESS) and investigated cognitive function and depression using the Computerized Neuropsychological Test and the Beck Depression Inventory (BDI). Results : At baseline, SSS, ISI, PSQI, and BDI scores were significantly higher and visual continuous performance test (VCPT) and auditory continuous performance test (ACPT) scores were significantly lower in the insomnia than in the control group. Three weeks later, the patients who had received hypnotics had significantly higher ISI, PSQI, ESS, VCPT, ACPT, visual span forward and backward, and visual recognition test scores, and significantly lower BDI scores. Conclusion : Quality of sleep in patients with insomnia following brain tumor resection was initially poor but improved significantly after taking hypnotic medication. Further, the hypnotic medications appeared to contribute to the amelioration of cognitive impairments and depressive moods in patients who previously underwent brain tumor resection. We thus recommend the use of hypnotics for patients with brain tumors with insomnia.

Treatment of giant cell tumor of distal radius can be treated in several ways according to the aggressiveness of the tumor. But the management of giant cell tumor involving juxta-articular portion has always been a difficult problem. In some giant cell tumors with bony destruction, a wide segmental resection may be needed for preventing to recur. But a main problem is preserving of bony continuity in bony defect as well as preservation of joint function. We have attempted to overcome these problems by using a microvascular technique to transfer the fibula with peroneal vascular pedicle or anterior tibial vessel as living bone graft. From April 1984 to July 2005, we performed the reconstruction of wide bone defect after segmental resection of giant cell tumor in 14 cases, using Vascularized Fibular Graft, which occur at the distal radius. VFG with peroneal vascular pedicle was in 8 cases and anterior tibial vessel was 6 cases. Recipient artery was radial artery in all cases. Method of connection was end to end anastomosis in 11 cases, and end to side in 3 cases. An average follow-up was 6 years 6 months, average bone defect after wide segmental resection of lesion was 6.8 cm. All cases revealed good bony union in average 6.5 months, and we got the wide range of motion of wrist joint without recurrence and serious complications. Grafted bone was all alive. In functional analysis, there was good in 7 cases, fair in 4 cases and bad in 1 case. Pain was decreased in all cases but there was nearly normal joint in only 4 cases. Vascularized fibular graft around wrist joint provided good functional restoration without local recurrence.

Objective: The purpose of this study was to determine the utility of preoperative CT in predicting early recurrence of hepatocellular carcinoma after partial hepatic resection. Materials and Methods: Preoperative three-phase helical CT scans in 53 patients with hepatocellular carcinoma were retrospectively reviewed by two radiologists. In 27 patients (group I), HCC had recurred within six months, while 26 (group II) had remained disease free for at least two years. In each group, preoperative CT findings were evaluated in each group for the tumor size and number, the presence or absence of capsule, distinctness of tumor margin, perinodular extension, and the presence or absence of portal vein thrombosis. Results: In group I, a tumor capsule of tumor was seen in five of 27 patients (19%), and in group II, in 16 of 26 (62%) (p = .001). The tumor margin was distinct in eight patients (30%) in group I and in 20 (77%) in group II (p = .001). Multiple tumors, perinodular extension, and portal vein thrombosis were more frequently seen in group I but the differences were not statistically significant (p > .05). Tumor size was similar in each group (p > .05). Conclusion: Preoperative CT findings that may help predict the early recurrence of hepatocellular carcinoma after surgical resection are an absence of capsule of tumors and an indistinct margin. Reference to these findings during preoperative CT can guide clinicians in their choice of treatment.

Objective: To explore the value of porous titanium alloy plates for chest wall reconstruction after resection of chest wall tumors. Materials and Methods: A total of 8 patients with chest wall tumors admitted in our hospital from Jan. 2006 to Jan. 2009 were selected and underwent tumor resection, then chest wall repair and reconstruction with porous titanium alloy plates for massive chest wall defects. Results: All patients completed surgery successfully with tumor resection-induced chest wall defects being $6.5{\times}7cm{\sim}12{\times}15.5$ cm in size. Two weeks after chest wall reconstruction, only 1 patient had subcutaneous fluidify which healed itself after pressure bandaging following fluid drainage. Postoperative pathological reports showed 2 patients with costicartilage tumors, 1 with squamous cell carcinoma of lung, 1 with lung adeno-carcinoma, 1 with malignant lymphoma of chest wall, 2 with chest wall metastasis of breast cancers and 1 with chest wall neurofibrosarcoma. All patients had more than 2~5 years of follow-up, during which time 1 patient with breast cancer had surgical treatment due to local recurrence after 7 months and none had chest wall reconstruction associated complications. The mean survival time of patients with malignant tumors was ($37.3{\pm}5.67$) months. Conclusions: Porous titanium alloy plates are safe and effective in the chest wall reconstruction after resection of chest tumors.

Purpose: Lymphovascular invasion is a criterion for non-curative resection in patients who have undergone endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We aimed to determine the rate of extragastric metastasis (EGM) and identify the predictors of EGM in patients with negative resection margins (R0 resection) and lymphovascular invasion in post-ESD pathology. Materials and Methods: A total of 2,983 patients underwent ESD for EGC. Among them, 110 had a pathology of R0 resection and positive lymphovascular invasion. Patients underwent additional gastrectomy (n=63) or further follow-up without gastrectomy (n=47). Results: The 110 patients were assigned to one of the 3 groups according to ESD indications based on post-ESD pathology. The first group satisfied the absolute indication for ESD (n=18), the second group satisfied the expanded indications for ESD (n=34), and the last group satisfied the beyond indication (n=58). The number of occurrences of EGM in each group was 1 (5.6%), 3 (8.8%), and 3 (5.2%), respectively. The logistic regression analysis adjusted for age, sex, tumor size, and indication for ESD, showed that larger tumor size was associated with EGM (odds ratio, 1.76; 95% confidence interval, 1.00-3.10; P=0.048). In contrast, ESD indication criteria did not affect EGM (P=0.349). Conclusions: Tumor size was the only predictive indicator for EGM in patients who underwent R0 resection and lymphovascular invasion on post-ESD pathology. Even patients with pathology corresponding to the absolute indication criteria of ESD had lymphovascular invasion, which means that they require additional gastrectomy due to the risk of EGM.
