대장암이나 타 장기 암의 간전이 경우 간 절제는 비교적 좋은 결과를 가지는 치료 방법으로 보고되고 있으나, 위암의 간전이에 대한 치료로 절제 수술의 역할과 생존율에 대한 효과는 연구가 많지 않은 실정이다. 위암의 수술 전 진단 때나 수술 후 추적 검사 중 진단된 간전이의 경우 많은 예에서 다발성 전이, 좌, 우엽에 전이, 간외 전이, 복막 파종이나 다발성 림프절 전이 양상으로 절제 수술의 적응이 되지 못하는 악성 경로를 가지는 경우가 많다. 그러나 몇몇 보고에서는 수술 적응 대상 환자가 적으나 간절제 치료로 좋은 결과를 보고하는 경우도 있어 제한된 간전이 환자에 대한 맞춤 치료의 영역은 있다고 하였다. 위암의 간전이 절제 예에 대한 보고를 종합하여 보면 간전이 병소가 진단되는 시기가 예후에 중요하여 동시성으로 전이가 진단된 경우가 나쁘며, 절제연이 10 mm 이상 유지 될 때 좋은 결과를 보고하였다. 반면 전이 병소의 개수는 생존율 검사에서 통계학적 의미는 없는 것으로 보고 되었다. 또한 충분한 절제연을 확보하면서 해부학적 구역 절제 이상의 수술이 시행된 경우와 이시성 간전이가 좋은 생존율을 보이는 것으로 보고되었다. 또한 간 절제 수술 후 가장 많은 재발 병소는 역시 간으로, 재발 시 대부분 2년 내 사망을 초래하여 절제 후 보조항암화학요법 치료도 중요하다.

유방 MRI는 유방암의 유방촬영 스크리닝법에 대한 가장 정확한 보완 검사법이다. 아직까지 MRI 스크리닝의 효과에 대한 무작위 대조군연구가 없음에도 불구하고, 현재 미국암학회와 국립 종합암네트워크 (NCCN)에서는 MRI 스크리닝을 유방암 고위험여성에서 권고하고 있다. 국내에서는, 한 후향적 연구에서 유방암 환자의 반대쪽 유방암에 대한 MRI 스크리닝법이 유방촬영술과 초음파에서 발견하지 못한 암을 발견하고 이는 이후 유방암 발병을 감소시킴을 보고하고 있다. 국내에 유방촬영 스크리닝법의 보완법으로 MRI를 도입하기 위해서는 판독의 표준화와 교육, MR 유도하 조직검사법과 적절한 적응증의 확립, 비용-효용성에 대한 평가가 선결되어야 한다.

Spindle cell carcinoma (SpCC) is referred to as a variant of oral squamous cell carcinoma. It is also known as "sarcomatoid squamous cell carcinoma" because it consists of normal squamous carcinoma cells with spindle-shaped cells that appear similar to a sarcoma. The term, "second primary tumor" (SPT) or "double primary tumor", is proposed for a second tumor that develops independently from the first. SPTs can present as either synchronous or metachronous lesions. Synchronous SPTs are defined as tumors occurring simultaneously or within 6 months after the first tumor. The patient in this case, whose primary tumor was in the tongue, was diagnosed with SpCC with metastases to both neck lymph nodes. This case also exhibited a second primary cancer as a synchronous lesion in the thyroid gland, which is uncommon. All carcinomas, both in the tongue and thyroid gland, were removed surgically, and especially in the tongue, an anterolateral thigh free flap was performed successfully to replace the defect.

Objectives: The aim of this study was to determine the incidence and characteristics of second primary malignancy (SPM) in patients with head and neck squamous cell carcinoma treated at a tertiary care hospital. Materials and Methods: We retrospectively reviewed the medical records of 221 patients who underwent surgery with or without adjuvant treatment for head and neck cancer from 2000 to 2002. Data of age, sex, risk factors, sites of primary and SPM, TNM stage of primary tumor, incidence of SPM, and survival were collected from medical charts. Results: Eighteen patients developed SPM during a median follow-up of 67 months, with an overall incidence of 8.14%. In addition, 77.7% of SPMs occurred in the oral cavity, followed by 11% in the lungs. The 5-year overall survival after the diagnosis of SPM in the head or neck was 70%, compared to 30% for SPM in other body regions. Conclusion: Considering a high incidence of SPM, i.e., 8.14%, in a mean follow-up period of 67 months suggests the need for long-term follow-up. Since treatment of SPM has shown an acceptable survival rate, early detection and curative therapy should be emphasized.

Objective : Combined hyperative dysfunction syndrome (HDS) defined as the combination of HDSs such as trigeminal neuralgia (TN). hemifacial spasm (HFS) and glossopharyngeal neuralgia (GPN), which mayor may not occur simultaneously on one or both sides. We reviewed patients with combined HDS and demonstrated their demographic characteristics by comparing them with those of patients with a single HDS. Methods : Between October 1994 and February 2006, we retrospectively studied a series of 1,720 patients who suffered from HDS and found 51 patients with combined HDSs. We analyzed several independent variables in order to evaluate the prevalence and etiologic factors of combined HDS. Results : The combined HDS group accounted for 51 of 1,720 (2.97%) patients with HDS; 27 cases of bilateral HFS, 10 cases of bilateral TN and 14 cases of HFS with TN. Their mean age was 52.1 years (range, 26-79 years). There were 5 men and 46 women. Seven patients had synchronous and 44 patients metachronous onset of HDSs. By comparison of combined and single HDS groups, we found that age and hypertension were closely associated with the prevalence of combined HDS (p<0.05). Conclusion : This study revealed that combined HDS was very rare. Hypertension and age might be the most important causative factors to evoke combined HDS.

Purpose: Laparoscopic hernia repair in children is still controversial. The aim of this study was to report our long-term results of the laparoscopic hernia technique, which is based on the same surgical principles as conventional open herniotomy. Methods: Five hundred fourteen pediatric patients with inguinal hernia were included in this study under informed consent. All patients underwent a laparoscopic technique of sac transection and intracorporeal ligation. The asymptomatic contralateral inguinal ring was routinely explored and repaired if a patient had patent processus vaginalis on the contralateral side. Patients were prospectively followed for 5 years. Those who were lost to follow-up were excluded from the study. Perioperative complications and recurrences were evaluated. Results: The mean follow-up period was 29 months. Mean operation time was 27.5 minutes. Forty one percent of the patients had contralateral patent processus vaginalis. Only one hernia recurred (0.19%). We had one case of contralateral metachronous hernia (0.21%) during follow-up period. Conclusion: The long-term follow-up results of our study revealed that laparoscopic hernia sac transection and ligation can be a safe and effective alternative for conventional herniorraphy.

Despite the decreasing incidence and mortality from gastric cancer, it remains a major health problem worldwide. Ninety percent of cases are adenocarcinomas. Here, we report a case of gastric adenocarcinoma developed after successful treatment of prior primary gastric diffuse large B-cell lymphoma (DLBCL). Our patient was an elderly man with primary gastric DLBCL in whom complete remission was achieved after R-CHOP (cyclophosphamide, adriamycin, vincristine, prednisolone plus rituximab) chemotherapy. Helicobacter pylori infection persisted despite adequate treatment leading to sustained chronic gastritis. The mean time to diagnose metachronous gastric carcinoma was seven years. We believe that a combination of many risk factors, of which chronic H. pylori infection the most important, led to the development of gastric carcinoma following primary gastric lymphoma. In summary, patients who have been successfully treated for primary gastric lymphoma should be followed up at regular short intervals. H. pylori infection should be diagnosed promptly and treated aggressively.

The development of office-based, unsedated transnasal esophagoscopy (TNE) has proven to be a major technological advance and with time and experience the application of this technology is becoming more widespread. TNE has allowed otolaryngologists to perform a variety of diagnostic and therapeutic procedures in the office setting. Studies consistently demonstrate that the image quality and diagnostic capability of TNE is equivalent to conventional esophagoscopy. The modern TNE endoscopes offer high quality optics, air-insufflation, and irrigation capability through a 2-mm working channel, and the ability to perform biopsies and select procedures. In general, the role of TNE in the head and neck patient is three-fold : to screen for synchronous and metachronous esophageal squamous cell carcinoma (ESCC) ; to differentiate post-treatment changes/symptoms from malignancy ; and to perform certain office-based procedures. TNE offers many specific advantages to the head and neck patient that are not afforded by conventional esophagoscopy. Because of surgical and postirradiation changes, many HNSCC patients have trismus or neck stiffness preventing completion of conventional transoral esophagoscopy. Perhaps most importantly, TNE provides enhanced patient safety, increased tolerability, better practice efficiency, and cost savings. For these reasons, TNE has become a particularly useful tool in the otolaryngologist's armamentarium.

이시성 반대쪽 액와 림프절 전이는 유방암에서 드물게 발생하며, 현재 원격 전이로 분류되어 있다. 그러나 최근 연구들은 이것이 국소 질환으로 간주될 수 있기 때문에 적극적으로 완치를 위한 치료를 할 것을 제안했다. 이에 저자들은 유방암을 진단받은 지 22개월 후에 반대쪽 액와 림프절 전이가 확인된 67세 여성의 증례를 영상 소견과 함께 보고하고자 한다. 환자는 액와 림프절 절제 수술 후 보조 항암화학요법 및 방사선치료를 받았다. 수술 6개월 후 추적검사에서 종양 재발이나 전이의 증거는 없었다.
