Objective: Strategies for managing supratentorial primitive neuroectodermal tumors(PNETs) in children include surgical resection, craniospinal irradiation and chemotherapy. This study is performed in order to compare the efficacy of various methods of treatment and to describe its optimal management. Methods: We have reviewed all medical records and pathology slides of six children(four males and two females) with supratentorial PNET from November, 1987 to May, 2003. The extent of resection was confirmed by computed tomography and magnetic resonance studies. Results: The patients were aged 1 to 13 years and treated postoperatively with/without adjuvant therapy. Tumor location included was four cortical, one gangliobasal, and one pineal region. The presenting symptoms and signs consisted of increased intracranial pressure and focal neurological deficits such as seizure and hemiparesis. The treatment consisted of surgical resection alone in one patient, postoperative radiotherapy in one patient, postoperative chemotherapy in one, and postoperative radiotherapy with chemotherapy in three. Five patients lived more than 12 months after diagnosis and one patient among them has been living more than 5 years after diagnosis. Conclusion: We can improve the survival and prognosis of supratentorial PNET patients by radical gross total resection of tumor followed by craniospinal irradiation and aggressive chemotherapy. First of all, gross total resection of tumor is the most important among many factors.

Neuropathic cancer pain (NCP) is caused by nerve damage attributable to the cancer per se, and/or treatments including chemotherapy, radiotherapy, and surgery; the prevalence is reported to be as high as 40%. The etiologies of NCP include direct nerve invasion or nerve compression by the cancer, neural toxicity, chemotherapy, and radiotherapy. NCP is subdivided into plexopathy, radiculopathy, and peripheral neuropathies, among several other categories. The clinical characteristics of NCP differ from those of nociceptive pain in terms of both the hypersensitivity symptoms (burning, tingling, and an electrical sensation) and the hyposensitivity symptoms (numbness and muscle weakness). Recovery requires several months to years, even after recovery from injury. Management is complex; NCP does not usually respond to opioids, although treatments may feature both opioids and adjuvant drugs including antidepressants, anticonvulsants, and anti-arrhythmic agents, all of which improve the quality-of-life. This review addresses the pathophysiology, clinical characteristics and management of NCP, and factors rendering pain control difficult.

목적 : 국소 진행된 비인강암으로 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 환자들의 부작용 및 단기 생존율을 비교하기 위하여 본 연구를 시행하였다. 대상 및 방법 : 1989년 10월부터 1998년 5월까지, 비인강암으로 진단받고 유도 화학요법 혹은 동시 화학요법 및 방사선 치료를 받은 62명의 환자들을 대상으로 후향적 분석을 시행하였다. 유도 화학요법군은 50명, 동시 화학요법군은 12명이었다. 나이, 성, 전신 수행능력, 조직학적 유형 등은 양군에서 비교적 고르게 분포하였다. 병기 분포는, 유도 화학요법군의 경우 IIB가 $32\%$, III가 $30\%$, 그리고 IV가 $38\%$였으며, 동시 화학요법군은 각각 50, 33.3, $16.7\%$였다. 양군에서 화학요법 약제는 CF (cisplatin and 5-FU)였고, 약제 투여 방법은 동일하였다. Cisplatin $100\;mg/m^2$을 day 1에, 5-FU $1,000\;mg/m^2$을 day $2\~6$에 각각 정맥투여하였으며 3주 간격으로 반복하였다. 방사선 치료 종료시까지 시행된 화학요법의 횟수는 양군 모두 테$1\~3$회(중앙값 2회)였다. 방사선 치료는 양군 모두 일일선량 $1.8\~2.0\;Gy$를 주 5회 조사하였다. 총 방사선량은, 유도 화학요법군의 경우 $69.4\~86\;Gy$ (중앙 선량 73.4 Gy), 동시 화학요법군은 $69.4\~75.4\;Gy$ (중앙 선량 70.8 Gy)였다. 추적기간은, 유도 화학요법군의 경우 $9\~l16$개월(중앙값 40.5개월), 동시 화학요법군은 $14\~29$개월(중앙값 21개월)이었다. 결과 : 전체 환자에서 2년 생존율은 $78.7\%$였다. 치료 방법별 2년 전체 생존율은, 유도 화학요법군이 $77\%$, 동시 화학요법군은 $87\%$였으며(p>0.05), 2년 무병 생존율은 각각 $56\%$ 와 $81\%$였다(p>0.05). 최종 치료에 대한 완전 관해율은 $75.5\%$와 $91.7\%$로 동시 화학요법군에서 높았으나 통계학적 유의성은 없었다. 방사선 치료시 grade $3\~4$의 혈액학적 독성은 양군에서 차이가 없었고, grade 2의 백혈구 감소가 동시 화학요법군에서 많았다 $(18\%\;vs\;66.7\%)$. Grade $3\~4$의 점막염은 동시 화학요법군에서 많았다$(4.0\%\;vs\;33.3\%)$. 전체적으로 grade $3\~4$의 급성 부작용이 동시 화학요법군에서 빈번하였고$(6.0\%\;vs\;41.7\%,\;p=0.005)$, 부작용으로 사망한 경우는 없었다. 결론 : 국소 진행된 비인강암에서 동시 화학요법을 시행함으로써 치료의 반응율과 2년 무병 생존율이 향상되는 경향을 보였으나, 통계학적 의의는 없었다. 따라서, 좀더 많은 대조군과 장기 추적관찰이 요구된다.

Wilms' tumor is the most common malignant renal tumor in childhood. The brain metastasis of a Wilms' tumor with anaplastic histopathology is rare. We present the case of an 8-year-old girl with Wilms' tumor, who presented with multiple brain metastases 5 years after her primary diagnosis. The brain masses were diagnosed after a generalized tonic-clonic seizure attack. The big solid mass in the cerebellum was resected, and whole-brain radiotherapy was performed, after which, she succumbed to her disease. In the case of clinical suspicion, cranial surveillance should be included in the routine clinical work-up for Wilms' tumor. Combined aggressive therapy (surgery+radiotherapy+chemotherapy) should be applied whenever possible, for both better survival and palliative aspects.

Background: To evaluate risk factors for upper extremity lymphedema due to breast cancer surgery. Materials and Methods: Clinical studies published on PubMed, Ovid, EMbase, and Cochrane Library from January 1996 to December 2012 were selected. Results: Twenty-five studies were identified, including 12,104 patients. Six risk factors related to the incidence of lymphedema after breast cancer treatment were detected: axillary lymph node dissection (OR=3.73, 95%CI 1.16 to 11.96), postoperative complications (OR=2.64, 95%CI 1.10 to 6.30), hypertension (OR=1.83, 95%CI 1.38 to 2.42), high body mass index (OR=1.80, 95%CI 1.30 to 2.49), chemotherapy (OR=1.38, 95%CI 1.07 to 1.79) and radiotherapy (OR=1.35, 95%CI 1.10 to 1.66). We found significant protective factors for lymphedema: pathologic T classification (OR=0.57, 95%CI 0.36 to 0.91) and stage (OR=0.60, 95%CI 0.39 to 0.93), while some factors, like age, number of positive lymph nodes, number of lymph node dissection, demonstrated no obvious correlation. Conclusions: Axillary lymph node dissection, postoperative complications, hypertension, body mass index, chemotherapy, radiotherapy are risk factors for lymphedema after breast cancer treatment. Attention should be paid to patients with risk factors to prevent the occurrence of lymphedema.

Background: The effects of home nursing intervention on the quality of life in patients with nasopharyngeal carcinoma (NPC) after radiotherapy and chemotherapy are unclear. According to the characteristics of nursing home patients with nasopharyngeal carcinoma, we should continuously improve the nursing plan and improve the quality of life of patients at home. Materials and Methods: We selected 180 patients at home with NPC after radiotherapy and chemotherapy. The patients were randomly divided into experimental and control groups (90 patients each). The experimental group featured intervention with an NPC home nursing plan, while the control group was given routine discharge and outpatient review. Nursing intervention for patients was mainly achieved by regular telephone follow-up and home visits. We use the quality of life scale (QOL-C30), anxiety scale (SAS) and depression scale (SDS) to evaluate these patients before intervention, and during follow-up at 1 month and 3 months after the intervention. Results: Overall health and quality of life were significantly different between the groups (p<0.05), Emotional function score was significantly higher after intervention (p<0.05), as were cognitive function and social function scores after 3 months of intervention (p<0.05). Scores of fatigue, nausea and vomiting, pain, appetite and constipation were also significantly different between the two groups (p<0.05). Rates of anxiety and depression after 3 months of intervention were 11.1%, 22.2% and 34.4%, 53.3%, the differences being significant (p<0.05). Conclusions: NPC home nursing plan could effectively improve overall quality of life, cognitive function, social function (after 3 months) of patients, but improvement regarding body function is not suggested. Fatigue, nausea and vomiting, pain, appetite, constipation were clearly improved. We should further pursue a personalized, comprehensive measurements for nursing interventions and try to improve the quality of life of NPC patients at home.
