The effect of text message reminders on nausea, vomiting and quality of life in children with cancer receiving cisplatin

PURPOSE

This study was conducted to examine the effect of text message reminders on nausea, vomiting, and quality of life in children with cancer receiving cisplatin.

METHODS

The study was conducted with a pretest-posttest unpaired group model design. The study included 80 children with cancer and their parents (40 controls and 40 experiments) aged between 8 and 18 years, who were on cisplatin treatment, who did not have cognitive disability as a clinical diagnosis, who received chemotherapy during their stay in the clinic, who were literate in Turkish and who volunteered to participate in the study. The educational contents prepared by the researchers to reduce nausea and vomiting were sent to the parents in the experimental group in the form of a text message every day for three weeks. Descriptive statistics, correlation analysis, and regression analysis were used to evaluate the data.

RESULTS

While NVTS, ARINVc, ARINVp, Quality of Life Scale pretest and posttest mean scores of both 8-12 and 13-18 age control group children were similar, it was determined that the experimental group's posttest mean scores were higher than the pretest mean scores, and there was a statistically significant difference between the experimental group's pretest and posttest mean scores in terms of the group, time and group*time. In this study, the education program explains 42%, 15%, 16%, 43%, and 43% of the increase in the mean scores of NVTS, ARINVc, ARINVp, Quality of Life Scale Child and Parent Form, respectively, in children aged 8-12. Also, the education program explains 10%, 27%, 28%, 38%, and 39% of the increase in the mean scores of NVTS, ARINVc, ARINVp, Quality of Life Scale Adolescent and Parent Form, respectively, in children aged 13-18.

CONCLUSIONS

It has been observed that text message reminders effectively reduce the level of nausea and vomiting and increase the quality of life.

PRACTICE IMPLICATIONS

The results of this study, text message reminders can be applied as an alternative intervention method, and including technology-based practices in the care of children with cancer is important in increasing the quality of care.

Evaluation of Risk Factors Causing Ototoxicity in Childhood Cancers Located in the Head and Neck Region Treated With Platinum-based Chemotherapy

The aim of this study is to evaluate risk factors contributing to the development of ototoxicity in children who received platinum-based chemotherapy for malignancies located in the head and neck region. Eighty-four children who received platinum-based chemotherapy were included. Audiologic evaluations were performed before and after each chemotherapy session through pure tone audiometry, distortion product otoacoustic emissions, and auditory brainstem response tests. Ototoxicity was evaluated using Brock, Muenster, and Chang classifications. Factors such as cranial irradiation, cumulative doses of cisplatin, age, sex, cotreatment with aminoglycosides, schedule of platinum, and type of chemotherapeutic agent were analyzed. Using χ2 tests, all risk factors were matched with the 3 ototoxicity classifications, and multivariate analyses were conducted using statistically significant risk factors. In univariate analyses, being between 5 and 12 years of age, cranial irradiation and being treated with both cisplatin and carboplatin were found to be related to ototoxicity in all 3 classifications. Logistic regression modeling analyses with these 3 risk factors showed that being between 5 and 12 years of age and being treated with both cisplatin and carboplatin significantly increased the risk of ototoxicity.

Investigating the risk factors for antibiotic lock therapy failure in pediatric cancer: a single center retrospective analysis

BACKGROUND

Catheter-related bloodstream infection (CRBSI) is one of the most common complications of central lines. Data concerning the effectiveness and safety of antibiotic lock therapy (ALT), especially in pediatric hematology and oncology patients, have not yet reached sufficient levels of evidence. We aimed to share our center`s experience on ALT in pediatric cancer and to investigate the causes of ALT failure.

METHODS

All cases with CRBSI and treated with ALT administiration in children with cancer between January 2015 and May 2019 were reviewed. Patients characteristics, laboratory and clinical findings, treatments, outcome of ALT, recurrences and reinfections were recorded. Patients with successful and unsuccessful ALT outcomes were compared in order to identify the risk factors for ALT failure.

RESULTS

Sixteen eligible CRBSI treated with adjunctive ALT were identified. The most common pathogens were coagulase negative staphylococci (8/16, 50%). Treatment failure was observed in 31.2% (5/16). Younger age alone was an independent risk factor for treatment failure (0.9 vs 6.8 years, p = 0.038). Recurrence and reinfection rates were 23.1% and 16.7%. Mild bleeding occured in two cases (12.5%) and occlusion causing catheter removal was seen in one (6.3%).

CONCLUSIONS

ALT was found to be a safe modality with a success rate of 68.8% in children with cancer at our center and younger age was an independent risk factor for treatment failure. Future studies with larger sample sizes are needed to determine the factors affecting the ALT outcome, especially in childhood malignancies.

High-grade glioma of central nervous system: Single center treatment experience

e14040

Background: To evaluate characteristics and treatment responses of patients with high grade gliomas (HGG) in our center Methods: Medical files of patients with malignant CNS tumors between 1987-2020 were analyzed retrospectively. There were 44 patients with HGG. Results: Diagnosis of patients as follows: 21 pons glioma, 2 anaplastic astrocytoma, 11 anaplastic ependimoma, 7 glioblastoma multiforme, 1 glioblastoma, 2 gliomatosis cerebri. The median age at diagnosis was 6,5 yrs (7 – 17 yrs), M/F:25/19. Age distrubution: <5 yrs 12 patients, 5-10 yrs 18 patients, 10-18 yrs 14 patients. The most frequent complaints for pons gliomas: cranial nerve paralysis (52%), visial impairment (48%), headache (38%), power loss (43%) and speech disorder (30%). Surgery was performed to extrinsic component of mass in 3 patients of pons gliomas. For other HGG: 7 subtotal resection and 16 gross total resection had performed. Seven patients died before RT. And other 37 patients received radiotherapy. RT total doses varied between 50-60 Gy. Seven patients were not received chemotherapy, 3 of them died before chemo, and others received only RT. Chemotherapy protocoles were changed over the years: For pons gliomas, MOPP (Mechlorethamine, vincristine, prednisone, procarbazine) in 3 patients, NOPP (nitrosourea, vincristine, prednisone, procarbazine) in 2 patients, only ICE (Ifosfamide, carboplatin, cisplatin) in five patients, oral cyclophosphamide in one patient, temozolamide in one patient and temo + bevacizumab in one patient. Last 3 patients received nimotuzumab-vinorelbine after ICE and temo. For other HGGs, platin based regimens used fort he first line treatment. Temozolamide-bevacizumab, irinotecan-temsirolimus combinations were the other options as second and also third line treatments. Median progression free survival time was 6 mos (2 weeks -25 mos) for pons gliomas, for other gliomas median progression free survival time was 14 mos (0 -74 mos). For pons gliomas: Event free survival rate for 6 mos was 75%, for one year was 17%, One year, 18 mos, and two years overall survival rates were 84%, 52% and 10% respectively. For other HGGs: Event free survival rate for one year and two years were 57% and 17% respectively. One year and two years overall survival rates were 73% and 36% respectively. Conclusions: High grade glioma is a group of tumor in which still the helplessness experienced in treatment. Despite radiotherapy and chemotherapy, prognosis is very poor. The progression free and overall survival rates of patients were similar to literature. With new developments in molecular pathology, as the use of molecular target therapies, the progression free survival rates newly will improve.

Pediatric langerhans cell histiocytosis: single center experience over a 17-year period

This study aimed to analyze children with the diagnosis of Langerhans cell histiocytosis (LCH) who were diagnosed and treated between 1998-2015. Medical records were evaluated retrospectively for clinical and laboratory features, treatment details, and outcome. There were 20 patients, the median age of diagnosis was 37 months, M/F ratio: 1.5. Nine had single system (SS), 11 had multisystem (MS) LCH. Spontaneous regression occurred in three infants with skin limited LCH. Eight patients had risk organ involvement in MS-LCH group. The curettage alone was performed in only one case. Patients received LCH-II/ LCH-III based chemotherapy schema. Radiotherapy was performed to vertebral disease and residual craniofacial bone disease in four cases. The regression and relapse rates were 100% and 33% for SS-LCH. The regression and relapse rates were 73%, and 18% for MS-LCH. Two infants with MS-LCH died despite chemotherapy. Pulmonary and liver involvements affected outcome adversely in MS-LCH. Multidisciplinary treatment approaches are needed.

Child with RET proto-oncogene codon 634 mutation

İnce D, Demirağ B, Ataseven E, Oymak Y, Tuhan H, Karakuş OZ, Hazan F, Abacı A, Özer E, Mutafoglu K, Olgun N. Child with RET proto-oncogene codon 634 mutation. Turk J Pediatr 2017; 59: 590-593. Herein we reported a 7-year-old child with RET proto-oncogene c634 mutation. Her mother had been diagnosed with medullary thyroid carcinoma (MTC), and treated six years ago. Heterozygous mutation of the RET proto-oncogene at c634 had been detected in her mother. Genetic analysis showed the presence of the same mutation in our patient. Thyroid functions were normal. Serum calcitonin level was found mildly elevated. Parathormone (PTH) and carcinoembrionic antigen (CEA) levels were normal. Prophylactic thyroidectomy and sampling of cervical lymph nodes were performed. Histopathologic examination revealed hyperplasia in thyroid C cells, and reactive lymphadenopathy. The risk of MTC has been reported 100% through the life of patients with RET proto-oncogene mutation. It has been reported that particularly patients with c634 mutation have more risk of occurence of metastatic and progressive/recurrent MTC. Prophylactic `thyroidectomy, cervical lymph node dissection` before 5-years-of-age should be considered for these patients.

Analysis of genetic and non genetic risk factors for cisplatin ototoxicity in pediatric patients

OBJECTIVE

The aim of this study was to analyse the genetic and non genetic risk factors for cisplatin ototoxicity.

METHODS

This study was conducted on 72 children who received cisplatin based chemotherapy. Brock and Muenster classifications were used to evaluate ototoxicity seen in these children. 6 single nucleotide polymorphisms (SNP); ERCC1 rs 11615, GSTP1 rs1138272, GSTP1 rs1695, LRP2 rs 2075252, TPMT rs 12201199, COMT rs 9332377, were evaluated as genetic factors by real time PCR. Non genetic factors such as cranial irradiation, cumulative doses of cisplatin, age, gender, administration of other ototoxic drugs were analysed as well. By using Chi-square test, risk factors were matched with the ototoxicity classifications. Significant risk factors were reevaluated using logistic regression modelling.

RESULTS

According to univariate analyses, male gender, co-treatment with aminoglycosides and mutant genotype of GSTP1 rs1695 were significantly related with cisplatin ototoxicity. Logistic regression modelling analyses also showed that male gender, co-treatment with aminoglycosides were found to be significantly related with cisplatin ototoxicity. Mutant genotype of GSTP1 rs1695 was not found to be significant, but close to the level of statistical significance.

CONCLUSION

Male gender, co-treatment with aminoglycosides are significant risk factors for cisplatin ototoxicity in pediatric patients. Mutant genotype of GSTP1 rs1695 seems to be a genetic risk factor in univariate analyses, although not confirmed by multivariate analyses. Therefore, GSTP1 rs1695 SNP needs to be studied in larger series.
