RESUMEN
To assess whether prophylactic use of Levofloxacin would reduce the number of febrile neutropenia episodes during the induction phase, a single-centre, case-control study was carried out. Data was collected prospectively of patients who received Levofloxacin prophylaxis during the induction chemotherapy from September 2019 till October 2020. The cases were compared with historical controls who did not receive antibiotics prophylaxis. A total of 121 patients were enrolled, among which 61 patients were cases, whereas 60 patients were controls. The patients who received Levofloxacin prophylaxis had lower rate of febrile neutropenia episodes than patients who did not receive any prophylaxis (p≤0.01) (odds ratio [OR]:0.23, CI 95%). No significant difference in induction mortality was seen between the two groups (p≤0.14). Levofloxacin prophylaxis reduced the rate of febrile neutropenia episodes among patients, but it did not affect the infection related mortality.

BACKGROUND: Lymphomatoid granulomatosis (LYG) is a rare pediatric disorder driven by the Epstein-Barr virus and is considered as a part of the lymphoma spectrum. It is mostly associated with immune deficiency and patients on immunosuppressive therapy, especially with acute leukemia. It can present as a multisystemic disease, diagnosed on biopsy as atypical lymphocytes with an angiocentric pattern against a background composed of histiocytes, neutrophils, and extensive T-cell infiltration. OBSERVATION: We report 3 cases of children with Lymphomatoid granulomatosis, one with Langerhans cell histiocytosis. CONCLUSION: Combination chemotherapy was used for the treatment of Lymphomatoid granulomatosis; however, the prognosis is guarded. One of 3 patients is alive and in remission on the last follow-up visit at 15 months.

Constitutional Mismatch repair deficiency (CMMRD) is a cancer predisposition syndrome. Four main common malignancies seen are, haematological, brain tumours, colorectal cancers, and intestinal polyps. We are reporting a 10-year-old boy with CMMRD; diagnosed with hematological malignancies, followed by low grade glioma in thalamus. There was loss of PMS2, whereas immunostaining was retained for MLH1, MSH2 and MSH6. Early diagnosis of CMMRD is crucial especially in countries like Pakistan, where consanguineous marriages are common. Increasing awareness among the physicians will help in early diagnosis, surveillance and in providing appropriate genetic counselling to the family.

BACKGROUND: Low- and middle-income countries sustain the majority of pediatric cancer burden, with significantly poorer survival rates compared to high-income countries. Collaboration between institutions in low- and middle-income countries and high-income countries is one of the ways to improve cancer outcomes. METHODS: Patient characteristics and effects of a pediatric neuro-oncology twinning program between the Hospital for Sick Children in Toronto, Canada and several hospitals in Karachi, Pakistan over 7 years are described in this article. RESULTS: A total of 460 patients were included in the study. The most common primary central nervous system tumors were low-grade gliomas (26.7%), followed by medulloblastomas (18%), high-grade gliomas (15%), ependymomas (11%), and craniopharyngiomas (11.7%). Changes to the proposed management plans were made in consultation with expert physicians from the Hospital for Sick Children in Toronto, Canada. On average, 24% of the discussed cases required a change in the original management plan over the course of the twinning program. However, a decreasing trend in change in management plans was observed, from 36% during the first 3.5 years to 16% in the last 3 years. This program also led to the launch of a national pediatric neuro-oncology telemedicine program in Pakistan. CONCLUSIONS: Multidisciplinary and collaborative efforts by experts from across the world have aided in the correct diagnosis and treatment of children with brain tumors and helped establish local treatment protocols. This experience may be a model for other low- and middle-income countries that are planning on creating similar programs.

OBJECTIVES: The aim was to review outcome with residual disease at the end of first line chemotherapy in patients with extracranial germ cell tumor (GCT) in our resource limited setting. METHODS: A retrospective analysis of 196 patients with GCT recruited at Shaukat Khanum Memorial Cancer Hospital (SKMCH) from January 2008 to December 2016. Data fields included site, histopathology, stage, risk groups, baseline alpha fetoprotein, beta human chorionic gonadotropin levels, residuum after primary treatment, completeness of surgical excision and outcomes. Data analysis involved quantitative analysis, mean and median calculations, event free survival (EFS) and overall survival (OS) calculations using Kaplan-Meier curves. RESULTS: In 196 included patients, M:F ratio was 1. There were 81 (41.3%) adolescents. Alpha fetoprotein was >10,000 IU/L in 56 (28.6%) patients. Sixty-two (31.6%) patients had extragonadal disease. Most patients (n=137, 69.9%) presented with advanced stage (III/IV). Seventy-six patients had postchemotherapy residual disease (n=59 [78%] with partial response (PR) and 17 [22%] with no response [NR]). Five-year OS was 83% and EFS was 67%. Five-year EFS of patients with complete remission after primary chemotherapy was 85% versus 70% in patients with PR and 6% in those with NR (P=0.001). OS in patients with complete remission, PR and NR was 94%, 87%, and 46%, respectively. All patients with NR progressed or relapsed and 8/17 died. Four patients with normalized tumor marker response were found to have active tumor on resection of postchemotherapy residuum. CONCLUSION: Patients with postchemotherapy residual disease in pediatric extracranial GCTs, fare better if their residuum is resected compared with those who do not undergo resection.

Background and objective In low- and low-to-middle-income countries (LMICs), the incidence of treatment-related mortality (TRM) in patients with acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) is up to 52%. This study aimed to determine the mortality rate at the end of the induction phase of the treatment among patients with ALL and lymphoma at a tertiary care cancer center. Methods This retrospective study analyzed outcomes after induction chemotherapy in pediatric patients with acute leukemia and lymphoma at a tertiary care cancer center from January 2015 to December 2016. Information regarding demographics, clinical characteristics, and laboratory investigations were extracted and reviewed. Results Of the total 160 patients, 110 were males, and the mean age of the sample was 4.6 +2.8 years. B-cell leukemia (pre-B-ALL) was diagnosed in 84% (n=134), while 10% (n=6) had acute T-cell leukemia (pre-T-ALL) and 6% (n=10) had lymphoma. Sixteen patients (10%) died within the defined induction period, with 14 deaths occurring due to infections and two deaths resulting from chemotherapy-related toxicity. Conclusion Based on our findings, there is a significant prospect of mortality from infections during induction chemotherapy in patients with pediatric hematological malignancies.
RESUMEN
Osteosarcoma is the most common primary malignant bone tumor in children. In addition to pulmonary metastasis, computed tomography frequently detects indeterminate pulmonary nodules (IPN). We conducted this study to determine the clinical significance of IPN in terms of progression to pulmonary metastasis and its impact on survival. It was a retrospective cohort study of pediatric nonmetastatic osteosarcoma patients treated from January 2005 to December 2018. Baseline computed tomography scans were reviewed for the presence of IPN (defined as a single nodule of <10 mm or ≥3 nodules of <5 mm). Subsequent scans were reviewed for the development of pulmonary metastasis. Of 155 patients, 31.6% (n=49) had IPN at baseline. A total of 43% (n=21) of those with IPN subsequently progressed to pulmonary metastasis compared with only 26% (n=28) of those without IPN (P<0.001) with a relative risk of 1.6 (1.03 to 2.5) in the IPN group. Patients with ≥3 IPN at baseline were at significantly greater risk of pulmonary metastasis as compared with <3 IPN (P=0.013). Overall and event-free survival in patients with and without IPN was 58% and 35%, and 72% and 46%, respectively. Our results suggest that patients with IPN may be at greater risk for progressing to pulmonary metastasis.

OBJECTIVE: To determine the clinical outcome and significance of pathological necrosis after neoadjuvant chemotherapy. METHODS: The retrospective study was conducted in Shaukat Khanum Memorial Cancer Hospital and Research Center and comprised data from January 2010 to December 2015 related to young with newly diagnosed Ewing sarcoma on histopathology. Data was collected on patients aged <20 years of either gender along with primary tumour site, metastatic status, tumour volume, mode of local therapy, degree of necrosis post-surgery, tumour margins after resection, outcome at the end of treatment and at last follow-up visit. Tumours were categorised as grade I = little or no necrosis, grade II = 50-90% necrosis, grade III = 90-99% necrosis, and grade IV = 100% necrosis. Data was analysed using SPSS 20. RESULTS: Of the 124 patients, 89(72%) were non-metastatic; 35(28%) were metastatic; 37(29.8%) underwent surgery; 58(46%) received radiotherapy; 7(5.6%) received both surgery and radiotherapy; 22(17.7%) received no treatment. Histopathology report post-surgery showed little grade 1 necrosis in 10(8%) patients, grade II in 8(6.5%), grade III in 8(6.5%) and grade IV in 14(11%). Event-free survival in grade IV necrosis was 93% in 14 (11.3%) patients, EFS in grade III necrosis was 71% in 8(6.5%) patients , EFS in grade II necrosis was 22% seen in 9(7.3%) patients and EFS in grade- I necrosis was 35% seen in 14 (11.3%) patients. Overall survival in grade IV necrosis was 93% in 14 (11.3%) patients, OS in grade III 75% seen in 8(6.5%), OS in grade II 25% seen in 9(7.3%) and OS in grade I was 50% in 14(11.3%) patients. Event-free survival was 48 (38%) patients and overall survival of Ewing sarcoma patients was 52 (46.6%) patients respectively. CONCLUSION: Tumour necrosis and histopathological changes post-surgery were found to have great impact on survival outcome in Ewing Sarcoma.

PURPOSE: A considerable barrier to global pediatric oncology efforts has been the scarcity and even absence of trained professionals in many low- and middle-income countries, where the majority of children with cancer reside. In 2013, no dedicated pediatric hematology-oncology (PHO) programs existed in Ethiopia despite the estimated annual incidence of 6000-12000 cases. The Aslan Project initiative was established to fill this gap in order to improve pediatric cancer care in Ethiopia. A major objective was to increase subspecialty PHO-trained physicians who were committed to practicing locally and empowered to lead programmatic development. METHODS: We designed and implemented a PHO training curriculum to provide a robust educational and clinical experience within the existing resource-constrained environment in Ethiopia. Education relied on visiting PHO faculty, a training attachment abroad, and extraordinary initiative from trainees. RESULTS: Four physicians have completed comprehensive PHO subspecialty training based primarily in Ethiopia, and all have remained local. Former fellows are now leading two PHO centers in Ethiopia with a combined capacity of 64 inpatient beds and over 800 new diagnoses per year; an additional former fellow is developing a pediatric cancer program in Nairobi, Kenya. Two fellows currently are in training. Program leadership, teaching, and advocacy are being transitioned to these physicians. CONCLUSIONS: Despite myriad challenges, a subspecialty PHO training program was successfully implemented in a low-income country. PHO training in Ethiopia is approaching sustainability through human resource development, and is accelerating the growth of dedicated PHO services where none existed 7 years ago.

This study aimed to determine response rates, overall survival (OS), event-free survival (EFS) and toxicity profile of an outpatient chemotherapy regimen based on gemcitabine and vinorelbine (GV) for relapsed childhood Hodgkin lymphoma (HL). This was a retrospective study that included 41 patients up to the age of 18 years with relapsed HL. Twelve patients (29%) had primary progressive disease (PPD), 6 (15%) had early relapse (ER) and 23 (56%) had late relapse (LR). The overall initial response rate was 83% (LR: 87%, ER: 83%, PPD: 75%. p-value: .2). Three-year combined OS was 80% (LR: 89%, ER: 80%, PPD: 65%. p-value: .07) and EFS 71% (LR: 86%, ER: 62%, PPD: 47%. p-value: .01). There were no toxic deaths. Febrile neutropenia was observed in four patients (9.6%) and lung toxicity in 1 patient (2.4%). This study suggests that outpatient GV is an effective and low toxicity salvage regimen for relapsed childhood HL.

OBJECTIVE: To describe clinical features and treatment options in pediatric patients with ALCL (Anaplastic large cell lymphoma) and their outcome over a span of 10 years. STUDY DESIGN: A retrospective-observational study. PLACE AND DURATION OF STUDY: Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from January 2005 to December 2015. METHODOLOGY: Medical records of pediatric patients with anaplastic large cell lymphoma was retrospectively collected after IRB approval. Data was reviewed for patients confirmed on histopathology and age less than 20 years at the time of diagnosis to see clinical features and treatment outcomes. Descriptive statistics were applied. RESULTS: A total of 40 children, 27 males (67.5%) and 13 females (32.5%) with ALCL (CD30 +), were reviewed. B symptoms were present in 32 (80%) patients, nodal involvement in 39 (97.5%), and mediastinum involvement was present in 8 (20%) patients. Visceral (lung, liver, spleen) and cutaneous involvement was seen in 16 (40%) and 6 (15%) patients, respectively. ALK was positive in 19 patients (48%) and Bone marrow was involved in 3 patients (7.5%). Stage III was seen in 29 (72.5%). All patients were treated on ALCL 99 protocol. Five-year EFS (event-free survival) and OS (overall survival) was 30 and 60%, respectively. There were 7 relapses, 2 progressive disease, 16 death and 3 refusal for treatment. CONCLUSION: This analysis shows poor outcomes in pediatric ALCL. The most common cause of mortality was hematological toxicity and febrile neutropenia associated with it. Supportive care needs to be improved. Key Words: Clinical features, Outcomes, Anaplastic large cell lymphoma (ALCL), Children.

Constitutional mismatch repair deficiency (CMMRD) is an autosomal recessive disorder caused by biallelic mutations in DNA mismatch repair genes 1. These patients have clinical stigmata of neurofibromatosis 1 (NF-1) with childhood onset of hematological malignancies, high grade gliomas, and colorectal-cancers 2. We present a case of non-Hodgkin's lymphoma (NHL) who later on developed adenocarcinoma colon at an age of 11 years with significant family history of glioblastoma in elder brother and colonic cancer in mother. This is the first case of CMMRD in Pakistan who developed colonic neoplasm at the age of 11 years. Nearly 150 patients of CMMRD have been reported worldwide.
RESUMEN
PURPOSE: Hodgkin lymphoma is the most common cancer in children, adolescents, and young adults. Overall survival is approximately 80% to 90%. A subset of these patients has refractory disease or experience disease relapse. Conventional salvage therapies and autologous stem-cell transplantation is usually considered the standard of care for these patients. Our analysis reports outcomes in these patients. PATIENTS AND METHODS: After institutional review board approval, a retrospective analysis of patients with Hodgkin lymphoma who were up to 18 years of age and who had refractory or relapsed disease at Shaukat Khanum Memorial Cancer Hospital and Research Centre from September 2009 to December 2013 was performed. Patients who underwent high-dose chemotherapy followed by stem-cell rescue were included in this analysis. RESULTS: A total of 567 patients with Hodgkin lymphoma registered at the hospital. Sixty of the patients (10.6%) had either primary progressive or refractory disease or relapse after finishing with first-line chemotherapy. High-dose chemotherapy followed by stem cell was administered to 25 of these patients (42%). Thirteen patients (40%) had progressive disease (PD), five (22%) had early relapse, and seven (38%) had late relapse. A number of salvage regimens were used, including etoposide, prednisolone, ifosfamide, and cisplatin; dexamethasone, cytarabine, and carboplatin; and gemcitabine plus vinorelbine. Re-evaluation was performed before taking patients to a high dose, and it showed complete response in 17 patients (68%), partial response in six patients (24%), and PD in two patients (8%). Twenty-one patients (84%) are in remission after transplantation, with two patients (8%) having died as a result of disease progression and two patients (2%) having relapsed after treatment. Overall survival is 92% at 4 years, with event-free survival of 80% at 4 years. CONCLUSION: Our retrospective analysis shows good outcomes in patients who had PD or refractory disease. Disease response before transplantation is important in predicting outcomes.

PURPOSE: Hodgkin lymphoma (HL) is one of the most curable paediatric cancers, with long-term survival rates now exceeding 90% after treatment with chemotherapy alone or combined with radiotherapy (RT). Treatment options for Hodgkin's Lymphoma differ among various study groups and there is still no consensus regarding the standard treatment for Hodgkin's lymphoma. Taking into account the impact of treatment-related mortality in low- and middle-income countries we propose to study the the clinical features and treatment outcomes by using different chemotherapy protocols in Hodgk in s' s Lymphoma children's at Shaukat khanam hospital Lahore.. METHODS: Clinical data from a large regional cancer center Pediatrics patients with Hodgkin's Lymphoma from January 2009 till December 2015 was retrospectively collected after Institutional Review Board (IRB) approval. RESULTS: A total of 748 patients were reviewed retrospectively. Mostly (45%) were in 6-10 years age group. Male showed predominance ,male to female ratio was 4:1. B symptoms were present in 51%, bulky disease in 44% and ESR was more than 30mm in 26% of patients. CD 30 was positive in 95%, Bone marrow involved in 13% of patients. Stage I in 8%, stage- II in 27%, stage -III in 39% and stage IV in 26% was seen. COPDAc/ABVD was given in 412 patients, CHLVPP/ABVD in 176 patients, OEPA/COPP in 57 patients, OEPA in 35 patients, OEPA/COPDAC in 33 Patients and remaining 33 received various chemotherapy protocol combination. XRT was given in 17% of patients. Of these 86% of patients were alive ,5% patients died , 3% patients abandoned, 6% patients relapsed ,3% patients progressed while on chemotherapy. Five years Overall survival was 94% and 5 Years Event free survival was 91%. Minimum haematological and other toxicity was seen in patients who had received COPDac/ABVD when compared to other regimen. CONCLUSIONS: Hodgkin's lymphoma patients had good outcome with different chemotherapy regimens, however our experience showed that the COPDac/ABVD regimen wass better tolerated with minimum toxicity.

BACKGROUND: Outcomes of pediatric mature B cell non-Hodgkin's lymphoma in resource-challenged countries are negatively affected by an increased rate of early and toxic deaths. Aim of this study is to assess the rate of acute mortality and define significant risk factors present in children with mature B cell non-Hodgkin's lymphoma. METHODS: A retrospective analysis was done of patients with B cell non-Hodgkin's lymphoma from January 2012 till December 2016. Risk factors studied for acute mortality were malnutrition, stage, prior surgery with open laparotomy, lactate dehydrogenase levels, tumor lysis syndrome, sepsis, and fungal infection. RESULTS: A total of 233 patients were enrolled in the study. Eighty-five (36.4%) were below 15th percentile weight for age. Treatment was started in 226 patients. Eighty-eight percent of children showed a 20% response after COP pre-phase. Tumor lysis syndrome was developed in 20.6% (n = 48) children and 42.9% (n = 100) patients had sepsis, 71/100 patients had culture-proven sepsis. 19.7% (n = 46) patients developed fungal infection. There was 19.7% (n = 46) acute mortality. The most common cause of death was sepsis (n = 22, 47.8%) followed by acute renal failure secondary to tumor lysis syndrome. On multivariate analysis, three independent variables found significant for early death are malnutrition, sepsis, and tumor lysis syndrome. CONCLUSION: Rate of acute mortality in mature B cell NHL is high in our set up and significant risk factors are tumor lysis syndrome, sepsis, and malnourishment at the time of presentation.
RESUMEN
In pediatric population, the most common solid malignant tumor of the kidney is Wilms' tumor (WT). Incidence of Extra-Renal Wilms' Tumor (ERWT) is immensely unusual. Prognosis of ERWT is comparable to renal WT. Hence, diagnosis, staging workup and start of treatment in a timely manner is very essential. The most common location of ERWT is the retroperitoneum. The staging of ERWT is done according to National Wilms' Tumor Study group (NWTS). ERWT is considered as stage II or higher; because it is outside renal capsule. A 6-year boy presented with complaints of increased frequency of micturition and difficulty in urination for 15 months. Biopsy of bladder mass showed WT by immunohistochemistry stains such as WTI and Desmin. Cross-sectional imaging showed both kidneys clear of any tumor. Hence, the final diagnosis of ERWT was made.

OBJECTIVE: To determine the frequency of cytogenetic type and its significance in the prognostic outcome of the pediatric patients in acute lymphoblastic leukemia (ALL), aged 1 to 15 years, and also determine the importance of minimal residual disease (MRD) in the management of the condition. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: Pediatric Oncology Ward, Shaukat Khanum Cancer Hospital, Lahore, from January 2015 to July 2017. METHODOLOGY: Patients aged 1-15 years, diagnosed with ALL, were included. Studied variables were cytogenetic type and MRD outcome in patients with ALL. Patients under one year of age and more than 15 years, or those having comorbidities, were excluded. RESULTS: Total 150 patients' data were retrieved from the Hospital database. One hundred and thirty-three belonged to age 1 to 5 years group (89%) and 17 (11%) were in 5 to 10 years group. The mean age of the patient was 4.3 +3.1 years. One hundred and two (68%) were males; whereas, 48 (32%) were females. Pre B acute lymphoblastic leukemia was diagnosed in 139 (93%) patients and 11(7%) were diagnosed with Pre T acute lymphoblastic leukemia. Standard risk was observed in 120 (80%) patients and 30 (20%) patients were on high risk as per National Cancer Institute (NCI) Guidelines. Regimen A was used in 125 (83.3%), Regimen B in 16 (10.7%), and Regimen C in 9 (6%) patients. BCR-ABL was positive in 2 (1.30%), TEL-AML in 68 (45%), MLL in 5 (3.30%), and normal in 54 (36%). MRD at day 29 was negative in 40 (93%) and positive in 3 (7%). The karyotyping was done in 128 (85%) patients, out of which 68 (53%) were hyperploids, 41 (32%) euploid, and 19 (15%) were hypoploid. Death was observed in 22 (15%) patients. Nineteen (86%) deaths were due to fungal and bacterial sepsis; and disease-related deaths were noted in 3 (14%) patients. CONCLUSION: The role of MRD and cytogenetics in risk assessment has improved in the early prognosis determination.

BACKGROUND: Acute Lymphoblastic Leukaemia (ALL) is one of the most common haematological malignancies seen in children. Despite steadily improving long-term outcomes, infections remain a major cause of morbidity and mortality in children receiving therapy for leukaemia. The incidence and risk of invasive fungal infections (IFIs) continue to rise. In some settings, IFIs caused by moulds are more frequent than those caused by yeasts, and Aspergillus spp. is the most common pathogens. The aim of the study was to determine the frequency, type of fungal infection seen during induction chemotherapy and outcomes.. METHODS: This observational retrospective study was conducted in paediatric oncology department at Shaukat Khanum Cancer Hospital Lahore from January 2015 to December 2016 after taking International research board (IRB) approval. The study includes all the patients aged 1-15 who were diagnosed with acute lymphoblastic leukaemia while on induction chemotherapy. The data was retrieved of 165 patients from the hospital database after informed written consent.. RESULTS: The mean age of the patients was 4.6±2.80 with range 1-15years. Total 154 (93%) of the children were of age between 1-5 years whereas only 11 (6.7%) were between 5-10 years. Male sex was predominant in 117 (70.9%) and 48 (29.1%) were girls. Pre-B Acute lymphoblastic leukaemia was diagnosed in 93.3% of the patients and rest 11 (6.7%) were diagnosed with Pre-T Acute lymphoblastic leukaemia. NCI Standard risk patients were 132 (80%) and 33 (20%) were stratified as high risk. Fungal infections were documented in 18 (11%) patients out of which 7(39%) were probable infections, and only 11 (61%) were proven fungal infections. Aspergillus was the commonest organism in 5 (28%) patients. Death was observed in 21 (13%) patients and causes were sepsis due to infections in 18 (86%) out of which fungal infections were 11(61%), bacterial 4(22%), combine bacterial and fungal 3(17%). Remaining 3 (14%) patients death causes include, neutropenic colitis was observed in first patient, second patient died of infection without any identifiable focus, and third patient died due to chemotherapy related toxicity.. CONCLUSIONS: Our study concludes that the fungal infection was the most common cause of mortality in induction in our patients. A prospective study in the form of clinical trial is needed to see if use of prophylactic antifungal can improve outcomes in our setting.
