The cure rate of acute lymphoblastic leukemia (ALL) in children dramatically improved over past 5 decades from zero to about 80%. The main cause of improvement is owing to the development of chemotherapy by multicenter clinical trial of large study groups with the understanding of leukemia biology. Recently, pediatric ALL protocols were applied to the treatment of adolescent and even adult ALL patients. For nearly 30 years, clinical factors have been used to risk-stratify therapy for children with ALL, so that the most intensive therapies are reserved for those patients at the highest risk of relapse. The risk groups of ALL are divided as standard- (low- plus intermediate-), high- and very high-risk group according to the prognostic factors, and treatment results improved by this risk based treatment. The factors used to risk-stratify therapy include age, gender, presenting leukocyte count, immunophenotype, cytogenetic aberrations including ploidy and translocations, and initial response after 1 to 2 weeks of therapy. But treatment efficacy is the most important determinant and can abolish the clinical significance of most, if at all, prognostic factors. Today, in the era of intensive, multiagent regimens, there is increasing evidence that we have reached the limits of prognostic significance of currently applied clinical risk factors in childhood ALL. As the cure rate of ALL is about 80%, introducing new prognostic factors such as new molecular prognostic markers, new methods of assessment about minimal residual disease, and pharmacogenetic study, with the development of stem cell transplantation and molecular targeted therapy are needed to cure residual 20% of childhood ALL patients without short and long term complications.

Purpose: This study investigated the effects of healthy lifestyle interventions (HLSIs) on health-related quality of life (HR-QoL) in childhood and adolescent cancer survivors (CACS). Methods: Major databases were searched for English-language original articles published between January 1, 2000 and May 2, 2021. Randomized controlled trials (RCTs) and non-RCTs were included. Quality was assessed using the revised Cochrane risk-of-bias tool, and a meta-analysis was conducted using RevMan 5.3 software. Results: Nineteen studies were included. Significant effects on HR-QoL were found for interventions using a multi-modal approach (exercise and education) (d=-0.46; 95% confidence interval [CI]=-0.84 to -0.07, p=.02), lasting not less than 6 months (d=-0.72; 95% CI=-1.15 to -0.29, p=.0010), and using a group approach (d=-0.46; 95% CI=-0.85 to -0.06, p=.02). Self-efficacy showed significant effects when HLSIs provided health education only (d=-0.55; 95% CI=-0.92 to -0.18; p=.003), lasted for less than 6 months (d=-0.40; 95% CI=-0.69 to -0.11, p=.006), and were conducted individually (d=-0.55; 95% CI=-0.92 to -0.18, p=.003). The physical outcomes (physical activity, fatigue, exercise capacity-VO₂, exercise capacity-upper body, body mass index) revealed no statistical significance. Conclusion: Areas of HLSIs for CACS requiring further study were identified, and needs and directions of research for holistic health management were suggested.

Radiation therapy has been widely applied for cancer treatment. Childhood acute lymphocytic leukemia (ALL), characterized by frequent central nervous system involvement, is a well documented disease for the effect of prophylactic cranio-spinal irradiation. Irradiation, however, acts as an oncogenic factor as a delayed effect and it is rare that glioblastoma multiforme develops during the remission period of ALL. We experienced a pediatric radiation-induced GBM patient which developed during the remission period of ALL, who were primarily treated with chemotherapeutic agents and brain radiation therapy for the prevention of central nervous system (CNS) relapse. Additionally, we reviewed the related literature regarding on the effects of brain irradiation in childhood and on the prognosis of radiation induced GBM.

Background: Cancer in infants younger than one year of age represents a unique problem with distinct epidemiological, clinical and genetic characteristics compared with older age groups. No report is yet available from Iran regarding epidemiological and survival rate of cancers diagnosed in this age group. Materials and Methods: The population under study comprised of patients which were diagnosed and admitted to Ali-Asghar hospital between years 1996-2005. In total, 287 infants were included in the retrospective descriptive survey. Patient files were evaluated for age of patient at the time of diagnosis, sex, geographical residence, consanguinity of parents, histological diagnosis, site of cancer involvement, type of therapy, date of last follow-up and cause of death (if applicable). Results: The average age at the time of diagnosis was 7.2 months old. The most frequent malignancy was retinoblastoma (44%), followed by leukemia (19%) and neuroblastoma (10%), with five-year overall survival rates of 77.7%, 41% and 90%, respectively Parents of 40 infants (13.9%) had consanguinity relationships. Conclusions: Although we cannot make any conclusions regarding the incidence of infant cancer subtypes based on this study, survival rates for major types were similar to the developed countries, which signifies strict adherence to standards of care in Ali-Asghar hospital, the main infant cancer care centre in Iran. A Childhood Cancer Registry with high-resolution data collection and also advanced genetic testing is advocated for in-depth analysis of variation in incidence and survival.

Growth hormone (GH) treatment has been increasingly widely used for children with GH deficiencies as the survival rate of pediatric patients with malignancies has increased. Both GH and insulin-like growth factor-I have mitogenic and antiapoptotic activity, prompting concern that GH treatment may be associated with tumor development. In this review, the authors examined the relationship between GH treatment and cancer risk in terms of de novo malignancy, recurrence, and secondary neoplasm. Although the results from numerous studies were not entirely consistent, this review of various clinical and epidemiological studies demonstrated that there is no clear evidence of a causal relationship between GH treatment and tumor development. Nonetheless, a small number of studies reported that childhood cancer survivors who receive GH treatment have a small increased risk of developing de novo cancer and secondary malignant neoplasm. Therefore, regular follow-ups and careful examination for development of cancer should be required in children who receive GH treatment. Continued surveillance for an extended period is essential for monitoring long-term safety.

소아청소년기에 뼈의 통증은 일차진료에서 흔히 접할 수 있는 문제이다. 대부분은 성장통이나 스포츠 활동과 관련된 물리적인 원인에 의한 것이지만 급성 림프구성 백혈병, 신경모세포종, 원발성 골종양 등의 악성종양이 뼈의 통증으로 발현하는 경우도 있다. 뼈의 통증을 호소하는 소아청소년 중 악성종양으로 진단 받는 환자는 1% 미만으로 그 빈도가 매우 낮지만 진단과 적절한 치료가 지체되면 환아의 예후에 악영향을 미칠 수 있으므로 어떠한 경우에 악성종양을 의심해야 하는지 숙지해야 한다. 환아가 잠을 잘 수 없을 정도로 심한 뼈의 통증을 2주 이상 호소하며, 발열, 피로감, 야간발한 등의 전신증상이 동반되거나 림프절 비대, 간비장 비대, 사지 혹은 배가 부어 보이고 덩어리가 만져지면 CBC with differential count, 말초혈액 바른검사, CRP, ESR, 단순 방사선 촬영을 시행해야 한다. 위의 검사결과 이상소견이 발견되면 즉시 소아청소년 혈액종양 전문의에게 의뢰를 해야 할 것이다.

목적 : 암환자들은 암의 재발여부를 추적관찰 하기 위해 다양한 영상검사들을 시행하고 있다. 이러한 환자들의 흉부 방사선 추적검사에서 결절이 발견되는 경우에는 종양의 폐전이를 의심하는 것이 일반적이다. 그러나 다른 질환, 특히 우리나라에서 유병률이 높은 폐결핵도 감별해야 한다. 본 연구는 소아암 환자의 흉부 방사선 추적검사 도중 암의 전이로 오인된 폐결핵의 빈도와 그 임상양상을 분석하고자 하였다. 방법 : 2001년 1월부터 2007년 6월까지 원자력병원에서 암으로 진단된 18세 이하의 소아 환자 422명을 대상으로 하였고, 후향적으로 의무기록을 고찰하여 치료 과정 및 치료종결 후 추적관찰 중 암의 폐전이와 폐결핵이 발병한 경우를 찾아내어 그 임상 양상을 분석하였다. 결과 : 수술 후 암으로 오인된 폐결핵은 5례였다. 이들 5명 환자에서 2명은 기침과 가래 등의 호흡기 증상이 있었으며, 나머지는 특별한 소견이 보이지 않았다. 5명 모두 열, 체중 감소, 쇠약감 등의 전신증상은 관찰되지 않았다. 가족 내 결핵의 가족력을 가지고 있었던 경우는 1례 였고, 조직 항산성 염색을 시행하였는데, 이 중 1례가 결핵균 양성으로 드러났고 나머지 4례는 음성이었다. 결핵 피부반응검사 상 양성으로 나온 경우는 2례였으나 객담 검사는 모두 음성이었다. 비정형결핵과의 감별을 위하여 환자들의 폐병변 조직을 얻었으며 이것으로 Tb PCR 시행한 결과, 1례에서 양성소견이 관찰되었다. 5례 중 4례는 폐병변이 모두 폐결핵으로만 드러났으나 1 례는 특이하게도 폐결핵과 폐 전이가 병발하였다. 이 환자는 이후 종양이 재발해 사망하였다. 결론 : 소아암의 기저질환을 가지고 있었던 환자에 있어서 치료 과정 중 또는 추적 관찰 중 새로이 발견된 폐의 종괴를 진단할 때는 결핵의 가능성도 고려하여야 한다.

이 논문에서는 소아청소년 암환자 중 치료종료 2년 이상의 환자 293명를 대상으로 소아와 청소년을 구분해 삶의 질을 분석하였다. 기존 연구에서는 소아청소년 암환자의 삶의 질을 평가하기 위해서 소아암 환자와 환자의 부모가 느끼는 삶의 질을 비교하는 것이 대부분이었고, 소아청소년을 하나의 그룹으로 평가하는 것이 일반적이었다. 그러나 소아청소년 암환자의 폭넓은 연령을 하나의 기준으로 평가하는 것은 문제가 있다. 따라서 이 논문에서는 언어 이해정도에 따라 연령을 10-12세와 13-20세의 연령의 두 그룹으로 분류하고 한국어로 작성된 KMMQL-AF 설문지를 이용하였다. 2011년 7월 15일에서 2012년 1월 31일까지 전국 10대 지역 병원(국립암센터, 서울대학교병원, 한양대학교병원, 화순전남대학교병원, 충북대학교병원, 충남대학교병원, 전북대학교병원, 경상대학교병원, 원자력병원, 이화여대부속목동병원)에서 정확한 자료수집을 위해 전문가가 동반해 심층면접을 통해 추출된 서술적 조사연구이다.

Background: For children and adolescents with cancer, going back to school is a key milestone in returning to "normal life." Purpose: To identify the support vital for a successful transition, we evaluated the parents' needs and the challenges they face when their children return to school. Methods: This multi-institutional study was conducted by the Korean Society of Pediatric Hematology and Oncology. The written survey comprised 24 questions and was completed by 210 parents without an interviewer. Results: Most parents (165 of 206) reported that their children experienced difficulties with physical status (n=60), peer relationships (n=30), academic performance (n=27), emotional/behavioral issues (n=11), and relationships with teachers (n=4) on reentering school. Parents wanted to be kept informed about and remain involved in their children's school lives and reported good parent-teacher communication (88 of 209, 42.1%). Parents reported that 83.1% and 44.9% of teachers and peers, respectively, displayed an adequate understanding of their children's condition. Most parents (197 of 208) answered that a special program is necessary to facilitate return to school after cancer therapy that offers emotional support (n=85), facilitates social adaptation (n=61), and provides tutoring to accelerate catch up (n=56), and continued health care by hospital outreach and school personnel (n=50). Conclusion: In addition to scholastic aptitude-oriented programs, emotional and psychosocial support is necessary for a successful return to school. Pediatric oncologists should actively improve oncology practices to better integrate individualized school plans and educate peers and teachers to improve health literacy to aid them in understanding the needs of children with cancer.
