  • TEL-AML1 fusion oncogene (t 12; 21) is the most common chromosomal abnormality in childhood acute lymphoblastic leukemia (ALL). This translocation is associated with a good prognosis and rarely shows chemotherapeutic resistance to 3-drug based remission induction phase of treatment as well as overall treatment. Thus, the higher the frequency of this fusion oncogene, the easier to manage childhood ALL in a given region with less intensive chemotherapy. Although global frequency of TEL-AML1 has been reported to be 20-30%, a very low frequency has been found in some geographical regions, including one study from Lahore, Punjab, Pakistan and others from India. The objective of present study was to investigate if this low frequency of TEL-AML1 in pediatric ALL is only in Lahore region or similar situation exists at other representative oncology centers of Pakistan. A total of 167 pediatric ALL patients were recruited from major pediatric oncology centers situated in Lahore, Faisalabad, Peshawar and Islamabad. Patients were tested for TEL-AML1 using nested reverse transcription polymerase chain reaction (RT-PCR). Only 17 out of 167 (10.2%) patients were found to be TEL-AML1 positive. TEL-AML1+ALL patients had favorable prognosis, most of them (82.4%, 14/17) showing early remission and good overall survival. Thus, our findings indicate an overall low frequency of TEL-AML1 in Pakistan pediatric ALL patients, in accordance with lower representation of this prognostically important genetic abnormality in other less developed countries, specifically in south Asia, thus associating it with poor living standards in these ethnic groups. It also indicates ethnic and geographical differences in the distribution of this prognostically important genetic abnormality among childhood ALL patients, which may have a significant bearing on ALL management strategies in different parts of the world.

  • Background: Early in the 21st century, cancers are the second cause of death worldwide. Colon cancer is third most common cancer and one of the few amenable to early diagnosis and treatment. Evaluation of factors affecting this cancer is important to increase survival time. Some of these factors affecting all diseases including cancer are social determinants of health. According to the importance of this disease and relation with these factors, this study was conducted to assess the relationship between social determinants of health and colon cancer survival. Materials and Methods: This was a cross-sectional, descriptive study for patients with colon cancer registered in the Cancer Research Center of Shahid Beheshti University of Medical Science, from April 2005 to November 2006, performed using questionnaires filled by telephone interview with patients (if patients had died, with family members). Data was analyzed with SPSS software (version 19) for descriptive analysis and STATA software for survival analysis including log rank test and three step Cox Proportional Hazard regression. Results: Five hundred fifty nine patients with ages ranging from 23 to 88 years with mean${\pm}$standard deviation of $63{\pm}11.8$ years were included in the study. The five year survival was 68.3%( 387 patients were alive and 172 patients were dead by the end of the study). The Cox proportional hazard regression showed 5-year survival was related to age (HR=0.53, p=0.042 for>50 years versus<50 years old) in first step, gender (HR=0.60, p=0.006 for female versus male) in second step, job (HR=1.7, p=0.001 for manual versus non manual jobs), region of residency (HR=3.49, p=0.018 for west versus south regions), parents in childhood (HR=2.87, p=0.012 for having both parents versus not having), anatomical cancer location (HR=2.16, p<0.033 for colon versus rectal cancer) and complete treatment (HR=5.96, p<0.001 for incomplete versus complete treatment). Conclusions: Social determinants of health such as job, city region residency and having parents during childhood have significant effects in 5-year survival of colon cancer and it may be better to consider these factors in addition to developing cancer treatment and to focus on these determinants of health in long-time planning.

  • Cancer-testis antigens (CTAs) are a group of tumor-associated antigens with more than 140 members whose expression has been shown to be limited to gametogenic tissues and placenta among normal tissues. However, malignant tissues of different origins have shown aberrant and elevated expression of these antigens. Such a pattern of expression endows beneficial properties for use as cancer biomarkers as well as immunotherapeutic targets as a result of the immune-privileged status of the testes. CTAs have been shown to be expressed in pediatric brain tumors, different types of sarcomas, leukemias, and lymphomas as well as neuroblastomas. Although data regarding their expression pattern in childhood tumors are not as comprehensive as for adult tumors, it is supposed that CTA-based immunotherapeutic approaches can also be used for pediatric cancers. However, there are limited data about the objective clinical responses following immunotherapy in such patients. Here we try to review the available information.

  • 목적 본 연구는 함께 치료를 받았던 암 환우의 죽음이라는 간헐적이나 지속적으로 발생하는 사건에 노출된 청소년 소아암 생존자의 슬픔을 탐색하기 위해 시도되었다. 방법 자료는 만 13-18세의 소아암 청소년 생존자 12명과 반구조화된 면접(일대일면접, 전화면접, 인터넷 채팅), 자조 집단의 참여관찰, 그리고 인터넷 개인 홈페이지나 블로그에 올려 있는 참여자들의 글을 수집하였다. 근거이론방법론 분석의 일환인 Clarke (2005)의 상황분석을 이용하여 자료를 분석하였다. 결과 상황분석에 의거하여 세 가지 수준의 지도를 도식화하였다. 암 환우를 잃은 슬픔에 빠진 청소년 소아암 생존자와 관련된 모든 상황적 구성요소들이 첫 번째 상황적 지도의 두 가지 버전에 의해 마련되었고, 두 번째로 슬픔에 처한 청소년 소아암 생존자를 중심으로 주변 인물들의 관계 및 슬픔이 일어나는 주요 장소에 대한 사회적 세계 지도가 그려졌다. 마지막으로 타인과의 관계 수준에 따른 슬픔의 표출 정도를 위치 지도에 도식화하였다. 청소년 소아암 생존자의 슬픔은 어두운 잔존 기억에 대처하기 위해 내면의 자아와 의사소통하는 동시에 친구 및 가족과의 상호작용 속에서 끊임없이 자신의 생각, 감정, 행동을 협상하였다. 슬픔은 특히 어머니에게 표출하지 않고자 노력하였으며, 슬픔으로 초래되는 정신적 힘듦을 피하기 위해 아무렇지 않은 듯 혼자 시간 보내거나 의식적으로 암을 앓고 있지 않은 건강한 친구와의 관계맺음을 선호하였다. 결론 청소년 소아암 생존자의 슬픔은 다양한 상황적 맥락에 연루된 사회 환경적 요소들에 따라 숨겨지거나 표출되었다. 상황분석은 이러한 요소들 간의 관계를 시각적으로 정렬하며 비교, 분석하는 데 있어서 유용하였다.

  • Background: Osteosarcoma is the most common bone cancer in children, responsible for a high rate of amputation and death. This is the first long-term, population-based, epidemiologic and survival study in Thailand. Objective: To study the incidence and survival rates of pediatric osteosarcoma in Khon Kaen. Method: Childhood osteosarcoma cases (0-19 years) diagnosed between 1985-2010 were reviewed. The data were retrieved from the population-based data set of the Khon Kaen Cancer Registry and medical records from Srinagarind Hospital, Faculty of Medicine, Khon Kaen University. All cases were censored until the end of April 2012. The age-standardized incidence rate (ASR) was calculated using the standard method. Survival experience was analyzed using the standard survival function (STATA 9.0) and presented with a Kaplan-Meier curve. Results: 58 cases were enrolled. The overall ASR was 14.1 per million. Males and females were equally affected. The peak incidence was for 15-19 year-olds in both sexes (ASR=10.4 per million in males and 8.5 in females). The 5-year overall survival rate was 27.6% (95% CI: 15.8-40.8%). The median survival time was 1.6 years (95% CI: 1.2-2.1). In a subgroup analysis, the patients who received only chemotherapy survived longer (5-year survival 45.7%, median survival time 4.1 years, p=0.12). Conclusion: The incidence rate for childhood osteosarcoma was slightly less than those reported for Western countries. The survival rate was also lower than reports from developed countries. Further evaluation of the treatment protocol and risk factor stratification is needed.

  • Purpose: This study was conducted to identify late school-aged children‘s knowledge, and practical will in the practice of cancer prevention lifestyle, and to examine the relations between these variables and factors that influence practice. Methods: The participants included 525 fifth and sixth grade students from 8 elementary schools in J and S cities. Data were collected in December 2008 using self-report questionnaires developed by the authors and were analyzed using the SPSS program. Results: Mean scores were, for knowledge of cancer prevention lifestyle, $0.76{\pm}0.11$ out of a possible 1, practical will, $4.05{\pm}0.55$ out of a possible 5, and practice, $3.66{\pm}0.41$ also out of 5. There were differences in knowledge (F=4.39, p=.013), practical will (F=18.35, p<.001), and practice (F=29.13, p<.001) according to academic achievement and in practical will (F=3.68, p<.001) and practice (F=3.01, p=.003) according to grade. There were positive correlations between knowledge and practical will (r=.205, p<.001), knowledge and practice (r=.181, p<.001), practical will and practice (r=.628, p<.001). Practice will and knowledge of cancer prevention lifestyle showed a significant influence on practice. Conclusion: Results of this study indicate that effective strategies should be developed to motivate the practical will for the practice of cancer prevention lifestyle during childhood.

  • This study identified the impact of childhood cancer on the Korean family. The purpose was to contribute knowledge for family nursing and pediatric hospice care practice with sick children and their families. This descriptive study was conducted during a 6 month period with children who were being treated for cancer at six university hospitals in Seoul. The data were gathered from members of 68 families ; 24(Group A), with a child newly diagnosed with cancer : 27(Group B), with a child under treatment and without complications, and 17 (Group C), with a child in relapse. Medical records, structured questionnaires and interviews were used for data collection. The questionnaires and interview schedules had been used previously in Martinson's research in the USA and China. The findings, conclusions, and suggestions are as follows. 1. The impact of childhood cancer on the family. Members of the family experienced fear, helplessness, guilty feelings, and anger at the time of the initial diagnosis and at relapse. Mothers complained of headache, anorexia and poor appetite, weight loss, sleep disturbance, and bad dreams. Many of the fathers either lost or changed jobs, and all working mothers stopped working. Half the parents reported changes in their marital relationships such as frequent quarrels but also stronger unity. Family members perceived cancer as the most frightening disease. Change in their world view was expressed as living on faith understanding suffering, determining to live a better life, wanting to live an upright life and valuing health as the most important. Religious activities are found most helpful through this difficult experience. Financial debt due to the treatment and care of the sick child, burdened 22 families. The above mentioned impact was most evidant in Group B(those presently undergoing treatment) and Group C(those in relapse). Findings indicate that nursing care should embrace the family of a child who is being treated for cancer. 2. Characteristics of the child with cancer The majority of the children in this sample had a diagnosis of leukemia. Their mean age was 6.8 and the ratio of boys to girls was 1.12 ; 1. The mean hospitalization frequency was 13.5 times and the mean duration of illness was 16.8 months. Most of 1.he children perceived cancer as the most frightening disease ; 32.7% of the children described their sickness as serious. Children in Group C were hospitalized more frequently, stayed in hospital for longer periods, and expressed their sickness as quite serious more often than the other two groups. These findings indicate how much comprehensive pediatric hospice nursing care services are needed along with relevant research and nursing education. 3. Characteristics of the families. The mean age of the father was 39.5 and the mother, 36,6 ; they are in their most productive life period. Mothers especially expressed feelings of financial uneasiness and powerlessness about giving up their jobs, and guilty feelings for not providing enough care and concern to other children due to taking care of the sick one. The burden of caring for the sick child can bring negative changes in family dynamics which they think provoke potential health problems in members of the family These findings suggest a need for nursing support and counselling resources. Findings also suggest the need for ethical inquiry about such questions as who should give information to the child in regard to diagnosis and prognosis, when, and how. Other suggestions included : 1) Quality health care for childhood cancer such as home care and pediatric hospice programs should be established. 2) Special and practical consideration for long-term patients should be made in the present insurance coverage. The reimbursement period for long-term patients should be lengthened. 3) Further in-depth qualitative studies are needed. 4) Education programs including guided practice experience for pediatric hospice care practitioners are needed.

  • Background: Complementary alternative medicine (CAM) use in children with cancer is widespread. Health-care providers (HCP) need to acknowledge and address this need. This study explored and compared perspectives on CAM of HCP and parents of young patients with cancer in Indonesia. Materials and Methods: We conducted a cross-sectional study using semi-structured questionnaires in HCP and parents of childhood cancer patients at an Indonesian academic hospital. Results: A total of 351 respondents participated: 175 HCP (response rate 80%) and 176 parents (response rate 80%). Parents were more likely than HCP to think that chemotherapy can cure cancer (80% compared to 69%, P=0.013). Nearly half of all parents (46%) and HCP (45%) doubted whether CAM can cure cancer. Parents were more likely than HCP to think that CAM can be helpful in childhood cancer treatment (54% compared to 35%, P=0.003). The most recommended CAM by HCP was self-prayer (93%). Reasons for recommending CAM were: hope for improvement of the child's condition (48%), patient wants to stop treatment (42%). Most discouraged CAM by HCP was by old-smart people (70%), the reasons being: lack of evidence for usefulness (77%), lack of CAM knowledge (75%). The proportion thinking that patients were unlikely to raise the CAM topic if they perceived that doctors were skeptical was higher in parents than in HCP (52% versus 1%) (P<0.001). Most HCP (71%) and parents (77%) acknowledged that their knowledge about safety and efficacy of CAM was inadequate (P=ns). The proportion that wanted to learn or read more about CAM was higher among parents than HCP (48% compared to 31%, P=0.002). Conclusions: HCP and parents have different perspectives on CAM use in children with cancer. HCP should enhance their CAM knowledge and encourage open communication about CAM with parents. If doctors' skepticism is perceived, parents are unlikely to raise CAM as a topic.

  • Neuroblastoma arises from the primitive neural crest cells, and is a common malignancy in childhood. The clinical features are characterized by biological heterogeneity. Neuronal degeneration and differentiation occur in some patients. However treatment in the high risk group accounting for approximately half, has not been satisfactory despite a multimodal approach. Therefore, effective treatment is determined by the risk group of prognostic factors, such as age at diagnosis, stage of disease, pathological finding and N-myc amplification. Neuroblastoma can be diagnosed prenatally, which suggests its origin during the normal embryogenesis. Recent knowledge of molecular biology, such as Trk genes, and the concept of cancer stem cells have given us some improved understanding on this disease. Currently, targeted therapies based on the molecular biology of neuroblastoma are under investigation and increasing survival rate and decreasing late complications could be appreciated.
