Hepatic metastasis of early gastric cancer (EGC) following subtotal gastrectomy with lymphadenectomy is rare. We report the case of a 61-year-old male patient who was diagnosed with EGC that was initially treated using endoscopic submucosal dissection (ESD) and subsequently underwent laparoscopic subtotal gastrectomy. Histopathological examination of the patient's ESD specimen showed a moderately differentiated tubular adenocarcinoma invading the submucosa without lymphatic invasion. The deep margin of the specimen was positive for adenocarcinoma, and he subsequently underwent laparoscopic distal gastrectomy. The patient developed liver metastasis 15 months after the operation and then underwent liver resection. Histology of the resected specimen confirmed the diagnosis of two foci of metastatic adenocarcinoma originating from stomach cancer. Immunohistochemical analysis of the specimen demonstrated overexpression of human epidermal growth factor receptor 2. The patient was treated with trastuzumab in combination with chemotherapy consisting of capecitabine and cisplatin. Twenty-four months after the operation, the patient remained free of recurrence.

Objective : A spinal cord subependymoma is an uncommon, indolent, benign spinal cord tumor. It is radiologically similar to a spinal cord ependymoma, but surgical findings and outcomes differ. Gross total resection of the tumor is not always feasible. The present study was done to determine the clinical, radiological and pathological characteristics of spinal cord subependymomas. Methods : We retrospectively reviewed the medical records of ten spinal cord subependymoma patients (M : F=4 : 6; median 38 years; range, 21-77) from four institutions. Results : The most common symptoms were sensory changes and/or pain in eight patients, followed by motor weakness in six. The median duration of symptoms was 9.5 months. Preoperative radiological diagnosis was ependymoma in seven and astrocytoma in three. The tumors were located eccentrically in six and were not enhanced in six. Gross total resection of the tumor was achieved in five patients, whereas subtotal or partial resection was inevitable in the other five patients due to a poor dissection plane. Adjuvant radiotherapy was performed in two patients. Neurological deterioration occurred in two patients; transient weakness in one after subtotal resection and permanent weakness after gross total resection in the other. Recurrence or regrowth of the tumor was not observed during the median 31.5 months follow-up period (range, 8-89). Conclusion : Spinal cord subependymoma should be considered when the tumor is located eccentrically and is not dissected easily from the spinal cord. Considering the rather indolent nature of spinal cord subependymomas, subtotal removal without the risk of neurological deficit is another option.

Objective : Angiolipomas are usually found in the subcutaneous tissue of the trunk and limbs. Spinal angiolipomas (SALs) are uncommon and have rarely been reported. We report a series of nine SALs patients who received surgical treatment in our department. To summarize the clinical characteristics of SALs, propose our surgical strategies, and evaluate the effects of the operation. Methods : This was a retrospective review of nine SALs patients who received surgical treatment from August 2015 to March 2020. Total or subtotal resection was determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. The outcomes were assessed based on the modified Japanese Orthopaedic Association (mJOA) scoring system utilized before surgery and at various follow-up points. Results : Among the nine patients, the mean mJOA score before surgery was 6.6±2.3, compared with 10.1±1.1 at the last follow-up time point (33.4±11.8 months). All patients achieved good outcomes, even in cases of subtotal resection. Conclusion : Early surgical resection of SALs is recommended, and the specific procedures should be determined by the axial localization (dorsal or ventral) and the extent of intervertebral foramen involvement. Most of the patients had a good prognosis, even in cases of subtotal resection.

A 6-year-old intact male Cane Corso dog weighing 40 kg with a 2-month history of dysuria, dyschezia, anorexia, intermittent panting, and penile discharge presented to the Veterinary Medical Teaching Hospital of Jeju National University. Examination revealed a giant paraprostatic cyst (PPC) that occupied a large part of the abdomen and caused displacement of organs. Radiography, ultrasound, and computed tomography (CT) scans confirmed that the PPC had spread to the pelvic regions. Subtotal resection was performed, leaving two sites with PPC remnants. One site was the prostate gland, which communicated with, and adhered to, the PPC; the other site was the pelvic region, where the PPC had spread. The reason for leaving two remnants was that an anatomical approach for complete resection was difficult, and to avoid complications associated with prostatic urethra damage. Routine omentalization and castration were performed. Partial cystectomy was performed because of the presence of a diverticulum-like lesion in the ventral part of the urinary bladder. The patient's clinical symptoms, including dysuria, completely resolved, and voluntary urination was possible 1 day post-operatively. Histopathological examination revealed osseous metaplasia of the PPC. The patient was well-managed and had no post-operative complications or recurrence until day 180 of follow-up.

Purpose: In resectable gastric cancer, choice regarding the extent of resection depends on tumor size, location, and distance from resection margin. However, there remains controversy for choice of resection for tumors in the middle third of the stomach. This study investigated patients who underwent gastrectomy in order to analyze the differences between total gastrectomy (TG) and subtotal gastrectomy (STG). Materials and Methods: From 2000 to 2006, 125 patients with a tumor in the middle third of the stomach underwent radical gastric resection at EUMC. We retrospectively conducted comparative analysis for the differences in clinicopathological characteristics and prognosis between TG and STG. Results: The average tumor size was 6.7 cm for TG, and 4.1 cm for STG. The number of metastatic lymph nodes were 13.3 for TG, and 3.7 for STG. Patients with more advanced cancer were more likely to receive TG. The 5-year survival rate for TG was lower (38.1%) than STG (69.0%). However, if tumor stages were stratified, there was no significant difference in the survival rate. Histologically, for the undifferentiated type of cancer (Stage 1, 2), the 5-year survival rate of STG was higher (88.1%) than TG (75.0%). Conclusions: Comparing patients with tumors in the middle third of the stomach who underwent TG and STG, there was no statistically significant difference in the 5-year survival rate. If stages were stratified, the clinicopathological characteristic becomes a key factor in deciding the prognosis, rather than the choice of resection. Thus if the radical resection margin can be obtained for a tumor in the middle third of the stomach, STG is considered instead of TG.

Objectives : The Objective of this study was to analyze the prognostic factors affecting survival in the patients with glioblastomas. Methods : We retrospectively studied 55 consecutive patients with glioblastomas who were admitted to neurosurgery department from January 1988 to March 1998. Fifteen pateients were excluded from the analysis because of follow-up loss and surgical motality. There were 24 male and 16 female patients, with a mean age of 51 years. Surgery consisted of biopsy in 4(10.0%) patients, subtotal resection in 9(22.5%) patients and gross total resection in 27(67.5%) patients. Nine(22.5%) patients received second operation. Twenty-eight(70%) received postoperative radiation therapy. Various levels of radiation dose were used, 6,000 rad over 7 weeks in most cases. The variable factors were examined for their relationship with survival ; age at the time of diagnosis, gender, duration of neurological symptoms, preoperative neurological state(Karnofsky performance score), extent of surgical resection, location of tumor, reoperation, and postoperative radiotherapy and chemotherapy. Result : The mean survival time was 55 weeks, three(7.5%) of the 40 patients survived more than two years. Survival time with biopsy only cases was 24 weeks, for those with subtotal resection 43 weeks, and for those with gross total resection 67 weeks. A mean survival time from the time of reoperation was 42 weeks. Statistically significant survival factors in glioblastoma were extent of surgical resection, postoperative radiotherapy and reoperation. Summary : Results of our series support the views that the extent of surgery, reoperation and postoperative radiation are important prognostic factors. We also recommend radical tumor removal, postoperative radiotherapy and reoperation, if possible.

Purpose: Quality of life (QOL) assessment should be applied in surgical settings to compare treatment options. We compared QOL after a subtotal versus a total gastrectomy for gastric cancer to identify which resection would produce a better QOL for the patient. Patients and Methods: We studied 362 patients with no evidence of recurrent disease after curative surgery for gastric cancer. The QOL was measured by assessing patient health perceptions according to the Spitzer index and Troidl score and by treatment-specific symptoms according to Korenaga and others with some modifications. High scores reflect a better QOL. Results: The mean score of the Spitzer index was $8.87\pm1.36$ after a subtotal gastrectomy and $8.80\pm1.23$ after a total gastrectomy. More than $80\%$ of the patients in both groups maintained good quality of life when measured by the Spitzer index. The mean Troidl score was $10.41\pm2.12$ after a subtotal gastrectomy and $9.79\pm2.16$ after a total gastrectomy (p=0.033). Swallowing difficulty was more frequent after a total gastrectomy (p=0.002). There was a statistically significant difference in the meal size (p=0.044). Other variables of the Troidl score revealed no statistically significant differences. Dizziness was significantly more frequent after a total gastrectomy than after a subtotal gastrec tomy (p=0.009). Conclusion: We conclude that in terms of postoperative quality of life, a subtotal gastrectomy has advantages over a total gastrectomy. In those cases where an adequate proximal safety margin can be achieved by a subtotal gastrectomy, that procedure is preferable to a total gastrectomy.

Purpose : To evaluate the role of postoperative radiotherapy in the management of primary or recurrent intracranial meningiomas. Methods and Materials : A retrospective review of 34 intracranial meningioma patients referred to the Yonsei Cancer Center for postoperative radiotherapy between 1981 and 1990 was undertaken. Of the 34 patients, 24 patients received elective postoperative radiotherapy after total or subtotal resection(Group 1), and 10 patients received postoperative radiotherapy as a salvage treatment for recurrent tumors(Group 2). Ten patients received postoperative radiotherapy after total resection, and twenty-four after subtotal resection. Ten patients who had total tumor resection were referred for radiotherapy either because of angioblastic or malignant histologic type(4 patients in Group 1) or because of recurrent disease after initial surgery(6 patients in Group 2). Radiation dose of 50-56 Gy was delivered over a period of 5-5.5 weeks using 4MV LINAC or Co-60 teletherapy unit. Results : Overall actuarial progression free survival(PFS) at 5 years was $80\%$. Survival was most likely affected by histologic subtypes. Five year PFS rate was $52\%$ for benign angioblastic histology as compared with $100\%$ for classic benign histology. For malignant meningiomas, 5 year PFS rate was $44\%$. The recurrence rates of classic, angioblastic, and malignant type were $5\%(1/21),\;80\%(4/5)$, and $50\%(4/8)$, respectively. The duration between salvage post-operative radiotherapy and recurrence was longer than the duration between initial surgery and recurrence in the patients of group 2 with angioblastic or malignant histology. Conclusion . Postoperative radiotherapy of primary or recurrent intracranial meningiomas appears to be effective modality, especially in the patients with classic meningiomas. In angioblastic or malignant histologies, a more effective approach seems to be needed for decreasing recurrence rate.

Objective : The aim of this study was to describe a single center's experience in the management of craniopharyngiomas in children over a 15-year period. Methods : The clinical records of pediatric patients treated for craniopharyngiomas between December 1995 and February 2011 were reviewed. Thirty-five pediatric patients diagnosed with craniopharyngioma were treated, and their medical records and imaging data were analyzed retrospectively. Results : The mean follow-up duration was 76 months (range, 10-195). Overall survival and local control rates at 10 years were $94.7{\pm}5.1%$ and $37.1{\pm}11.9%$, respectively. The female-to-male ratio was 16 : 19, and the mean age was 8.6 years (range, 1-17). Initially, gross total resection (GTR) was performed in 30 patients; subtotal resection (STR) followed by radiotherapy was performed in 5 patients. Of the 14 cases that showed recurrence after GTR, 5 patients were treated with GTR, 1 with radiation therapy (RT), 4 with gamma knife radiosurgery (GKRS), and 4 with subtotal resection followed by RT. No patients who underwent RT or GKRS had recurrences. Two cases with recurrence after STR followed by RT were treated with GTR. One patient died of hormonal insufficiency 64 months after the first surgery. The overall median time progression was 51.2 months (range, 3-182) : 49.7 months in the patients who underwent GTR and 60.2 months in the patients who underwent STR followed by RT. Conclusion : If safe resection is possible, GTR at the initial treatment should be attempted to reduce the tumor recurrence. However, if the tumor recurs after the first surgery, RT or GKRS with/without reoperation may be an effective salvage treatment for recurrent craniopharyngioma.
