Purpose : To assess the efficacy and toxicity of the preoperative radiotherapy with or without chemotherapy in locally advanced rectal cancer Methods : Forty three patients (clinically diagnosed stages above or equal to Astler-Coiler stage B2 without distant metastasis) were assigned to preoperative radiotherapy alone arm (n=16) or combined preoperative radiotherapy and chemotherapy arm (n=27). Preoperative radiotherapy of 4500 cGy to whole pel-vis +/-540 cGy boost to primary site and concurrent chemotherapy of 2 cycles of 5-FU (500 mg/$m^2$) and leucovorin (20 mg/$m^2$) were used. Fifteen patients of preoperative radiotherapy alone arm and 19 of combined arm received surgical resection after preoperative treatment. Results : During the preoperative treatment, no significant complication was developed in both groups. Pathologic results were as follows; complete remission 1, Bl 1, B2 6, C1 2, C2, 5 in preoperative radiotherapy alone arm and complete remission 2, Bl 8, B2 4, C2 3, D 2 in combined arm. Postoperative complications were delayed perineal wound healing in three patients, intestinal obstruction in three patients (one managed by conservative medical treatment, two by surgical treatment). Conclusion : The combined preoperative radiotherapy and chemotherapy arm was more effective in pathological response and lymph node negativity rate than the preoperative radiotherapy alone arm. Both the preoperative radiotherapy alone arm and the combined arm were generally well tolerated and did not result in an increased postoperative morbidity.

Purpose: We evaluated the socio-personal and clinical factors that can affect preoperative quality of life to determine how to improve preoperative quality of life in patients with gastric cancer. Materials and Methods: The preoperative quality of life data of 200 patients (68 females and 132 males; mean age $58.9{\pm}12.6years$) with gastric cancer were analyzed according to socio-personal and clinical factors. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core (QLQ) 30 and the EORTC QLQ-STO22, a gastric cancer-specific module, were used to assess quality of life. Patients were asked to complete the questionnaire preoperatively by themselves. Results: Patients with a higher academic background and stage I disease tended to have higher global health status scores. Highly educated younger men had better physical functioning scores. Highly educated and well-nourished patients with stage I cancer had higher role functioning scores. Married patients had better emotional scores. The symptom scales were affected by sex, age, education level, nutrition, and cancer stage. Conclusions: Preoperative quality of life in patients with gastric cancer can be improved by nutritional support and treatment of symptoms caused by disease progression. Psychological support may be helpful for patients with a poor quality of life.

In general, the skeletal class III has the characteristics of mandibular overgrowth with a normal maxillary growth or maxillary undergrowth with a normal mandibular growth And clinical and radiographic evaluations of the patient are needed. However, the treatment plan is not dependent on these evaluations alone, because patient's general condition and hope for aesthetics varies. The aim of this report is to consider the treatment of a medically compromised patient with an anterior open bite and skeletal class III, which showed a severe mandibular overgrowth. In 2003, a 17-year-old boy with epilepsy, mental retardation presented at our clinic complaining of concave profile. A clinical examination showed severe mandibular prognathism with an anterior open bite. The radiographic examination revealed a short cranial base, a moderate maxillary overgrowth, severe mandibular overgrowth and skeletal open bite tendency. In 2004, he was verified to have no potential of growth by hand-and-wrist radiographs and an endocrine examination. He completed the preoperative orthodontic treatment and orthognathic surgery (sagittal split ramus osteotomy, genioplasty). He was evaluated on the first visit, the preoperative period and the postoperative period with a clinical and radiographic examination. At the first visit, the patient showed moderate overgrowth of the maxilla, severe overgrowth of the mandible, and a subsequential skeletal open bite. After the preoperative orthodontic treatment (preoperative period), the patient showed the same skeletal problem as before and a decompensated dentition for orthognathic surgery. After orthognathic surgery, his profile had improved, but he had still a skeletal openbite tendency because the maxillary orthognathic surgery was not performed. Severe mandibular prognathism with a maxillary overgrowth and anterior open bite should be treated by bimaxillary orthognathic surgery. However, one-jaw orthognathic surgery on the remaining the skeletal open bite tendency was performed for his medical problem and facial esthetics. This subsequential open bite should be resolved with a postoperative orthodontic treatment.

위암은 치료에 있어서 조기 발견을 통한 수술 등에 의해서 치료율이 향상되었지만 조기 위암을 제외하고는 치료성적이 정체되고 있는 실정이다. 진단 당시 아직도 많은 환자들이 처음부터 수술이 어렵거나 수술이 가능하더라도 치료 후에 재발 등으로 인하여 예후가 좋지 않다. 이를 볼 때 위암의 치료에 수술 이외의 부가적인 치료가 필요하다고 보고 치료율 향상을 위한 많은 시도가 시행되어 왔다. 특히 다른 고형 암에서의 좋은 결과와 수술 전 항암 화학요법 치료의 이론적인 잇점으로 인하여 많은 기대를 가지게 하였으나 현재까지의 연구 결과 만을 볼 때는 그리 희망적이지 않다. 기존의 대부분의 연구가 2상 연구로 의미있는 결과를 유추하는데 문제점이 있고 3상 연구로 발표된 몇몇 연구는 드물기도 하지만 이를 수술 전 항암 항암화학 요법의 효과로 받아들이는 데는 문제가 많다. 순수하게 수술 전 항암 화학 요법 치료를 한 연구에서는 오히려 기대와 상반된 결과를 보이고 있다. 그러므로 현재까지의 연구 결과를 가지고 판단한다면 수술 전 항암 화학 요법의 치료는 임상 시험 범주 내에서 시행되어야 하며 임상에서 환자에게 권할 수 있는 하나의 표준 치료가 되기 위해서는 좀 더 연구가 필요하다. 현재까지의 비관적인 결과는 약제의 선택에 있어서 문제가 있으며 추후 신약 등을 포함한 약제를 이용한 연구가 필요한 실정이다.

Objective : It has been reported in recent studies that 50-80% of patients with cervical disc hernia have concomitant sleep disorders. The aim of this study was to evaluate the quality of sleep before and after surgical treatment in patients with cervical disc hernia and to assess the effects on treatment. Methods : The study included 32 patients performed discectomy and fusion with an intervertebral cage through the right anterior cervical approach. Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Pittsburgh Sleep Quality Index (PSQI) were applied to all patients preoperatively and at one month postoperatively. Results : The postoperative PSQI total points and all the PSQI subscale points, the ODI and VAS scores were significantly reduced compared to the preoperative values. A positive correlation was determined between the preoperative ODI points and the PSQI total points and sleep duration, sleep latency and daytime functional loss subscale points. A positive correlation was also found between preoperative ODI points and VAS points. A positive correlation was determined between the preoperative VAS points and and the PSQI total points and sleep duration, and sleep latency subscale points. A negative correlation was determined between the postoperative ODI and the daytime functional loss subscale points. Conclusion : The results of the study showed that in patients with cervical disc hernia, sleep quality and daytime functionality were negatively affected by severity of pain that limited daily activities. Bringing the pain under control with surgical treatment was observed to increase sleep quality. It can be concluded that when planning treatment for these patients, it should be taken into consideration that there could be a sleep disorder in addition to the complaints and symptoms such as pain, hypoestesia and loss of strength.

Background Lipedema is a condition consisting of painful bilateral increases in subcutaneous fat and interstitial fluid in the limbs with secondary lymphedema and fibrosis during later stages. Combined decongestive therapy (CDT) is the standard of care in most countries. Since the introduction of tumescent technique, liposuction has been used as a surgical treatment option. The aim of this study was to determine the outcome of liposuction used as treatment for lipedema. Methods Twenty-five patients who received 72 liposuction procedures for the treatment of lipedema completed a standardized questionnaire. Lipedema-associated complaints and the need for CDT were assessed for the preoperative period and during 2 separate postoperative follow-ups using a visual analog scale and a composite CDT score. The mean follow-up times for the first postoperative follow-up and the second postoperative follow-up were 16 months and 37 months, respectively. Results Patients showed significant reductions in spontaneous pain, sensitivity to pressure, feeling of tension, bruising, cosmetic impairment, and general impairment to quality of life from the preoperative period to the first postoperative follow-up, and these results remained consistent until the second postoperative follow-up. A comparison of the preoperative period to the last postoperative follow-up, after 4 patients without full preoperative CDT were excluded from the analysis, indicated that the need for CDT was reduced significantly. An analysis of the different stages of the disease also indicated that better and more sustainable results could be achieved if patients were treated in earlier stages. Conclusions Liposuction is effective in the treatment of lipedema and leads to an improvement in quality of life and a decrease in the need for conservative therapy.

Purpose: A phase II study was conducted to evaluate the safety and efficacy of preoperative, intra-arterial perfusion of epirubicin, etoposide, and oxaliplatin combined with oral chemotherapy S-1 (SEEOX) for the treatment of type 4 gastric cancer. Materials and Methods: A single-center, single-arm phase II trial was conducted on 36 patients with histologically proven type 4 gastric cancer without distant peritoneal or organ metastasis. Patients received 3, 21-day courses of SEEOX preoperative chemotherapy. The primary endpoint was overall survival (OS) and the secondary outcomes assessed were chemotherapeutic response, radical resection rate, pathological regression, toxicities, postoperative morbidity, and mortality. Results: All patients were at an advanced stage of cancer (stage III or IV) and completed the entire course of treatment. Based on changes in tumor volume and peritoneal metastasis, the objective response rate was 55.6% (20/36; 95% confidence interval [CI], 38.5%-72.6%) and the disease control rate was 69.4% (25/36; 95% CI, 53.6%-85.3%). The radical resection rate was 75% (27/36; 95% CI, 60.1%-89.9%) and the proportion of R0 resections was 66.7% (21/36; 95% CI, 50.5%-82.8%). The pathological response rate was 33.3%, of which 13.9% showed complete pathological regression. The median survival was 27.1 months (95% CI, 22.24-31.97 months), and the 2-year OS was 48.5% (95% CI, 30.86%-66.1%). Conclusions: Preoperative SEEOX is a safe and effective treatment for type 4 gastric cancer. Based on these preliminary data, a phase III study will be conducted to confirm the superiority of this regimen over standard treatment.

Bacillus Calmette-Guerin(BCG) lymphadenitis is a complication of post-BCG vaccination and its treatment is still controversial. Eighty patients who had been operated for BCG lymphadenitis from 1987 to 1996 were reviewed. Thirty-one of them were treated with antituberculous drugs(mean duration: 3 months) preoperatively and 49 patients were not given preoperative antituberculous medication. No one was treated with antituberculous drugs postoperatively. Operation methods were excision(72) and partial excision with curettage(8). There was no statistical difference in recurrence rate between groups In two patients(2.5 %) treated with preoperative antituberculous drugs, the lesions recurred after operation. The results suggest that preoperative antituberculous medication does not play any role in the treatment of BCG lymphadenitis and in preventing recurrence in surgically excised cases.

Purpose: To evaluate the treatment outcomes of patients with locally advanced rectal cancer treated with preoperative concurrent chemoradiotherapy (CCRT) or combined chemotherapy together with radiotherapy (CMT-RT) without surgery. Materials and Methods: A total of 84 patients with locally advanced rectal adenocarcinoma (stage II or III) between January $1^{st}$, 2003 and December $31^{st}$, 2013 were enrolled, 48 treated with preoperative CCRT (Gr.I) and 36 with combined chemotherapy and radiotherapy (CMT-RT) without surgery (Gr.II). The chemotherapeutic agents used concurrent with radiotherapy were either 5-fluorouracil short infusion plus leucovorin and/or capecitabine or 5-fluorouracil infusion alone. All patients received pelvic irradiation. Results: There were 5 patients (10.4%) with a complete pathological response. The 3 year-overall survival rates were 83.2% in Gr.I and 24.8 % in Gr.II (p<0.01). The respective 5 year-overall survival rates were 70.3% and 0% (p<0.01). The 5 year-overall survival rates in Gr.I for patients who received surgery within 56 days after complete CCRT as compared to more than 56 days were 69.5% and 65.1% (p=0.91). Preoperative CCRT used for 12 of 30 patients in Gr.I (40%) with lower rectal cancer demonstrated that in preoperative CCRT a sphincter sparing procedure can be performed. Conclusions: The results of treatment with preoperative CCRT for locally advanced rectal cancer showed comparable rates of overall survival and sphincter sparing procedures as compared to previous studies.
