Fulltext Efficacy of Oral Cryotherapy in the Prevention of Oral Mucositis Associated with Cancer Chemotherapy: Systematic Review with Meta-Analysis and Trial Sequential Analysis

Al-Rudayni AHM, Gopinath D, Maharajan MK, Veettil SK, Menon RK

Curr Oncol, 2021 07 29;28(4):2852-2867.
PMID: 34436016 DOI: 10.3390/curroncol28040250

BACKGROUND: This review aimed to evaluate the efficacy of oral cryotherapy in the prevention of chemotherapy-induced oral mucositis using meta-analysis and trial sequential analysis, as well as to assess the quality of the results by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.
METHODS: A comprehensive search of three databases including Medline, Embase and Central was performed to identify randomized controlled trials that used oral cryotherapy for the prevention of chemotherapy-induced oral mucositis. The primary outcome was the incidence of oral mucositis for trials employing oral cryotherapy as the intervention for the prevention of oral mucositis. The meta-analysis was performed using the random-effects model and random errors of the meta-analyses were detected by trial sequential analysis.
RESULTS: A total of 14 RCTs with 1577 participants were included in the present meta-analysis. Patients treated with oral cryotherapy were associated with a significantly lower risk of developing oral mucositis of any grade (risk ratio (RR), 0.67 (95% CI: 0.56-0.81, p < 0.05)). Findings from the subgroup analyses showed that oral cryotherapy significantly reduced the risk of oral mucositis in patients undergoing bone marrow transplantation (RR 0.69, CI: 0.54-0.89, p < 0.05) as well as chemotherapy (RR 0.66, CI: 0.58-0.75, p < 0.05). Findings from the trial sequential analysis suggested that the evidence on oral cryotherapy as a preventive intervention for oral mucositis in patients with solid malignancies receiving conventional chemotherapy was conclusive.
CONCLUSION: Oral cryotherapy is effective in preventing oral mucositis in patients undergoing chemotherapy for the management of solid malignancies. The use of oral cryotherapy in preventing oral mucositis in bone marrow transplantation settings showed promising efficacy, but the evidence is not conclusive and requires more high-quality randomized controlled trials.
Fulltext The Implementation of a Primary HPV Self-Testing Cervical Screening Program in Malaysia through Program ROSE-Lessons Learnt and Moving Forward

Woo YL, Khoo SP, Gravitt P, Hawkes D, Rajasuriar R, Saville M

Curr Oncol, 2022 Oct 02;29(10):7379-7387.

Program ROSE (removing obstacles to cervical screening) is a primary HPV-based cervical screening program that incorporates self-sampling and digital technology, ensuring that women are linked to care. It was developed based on the principles of design thinking in the context of Malaysia. The program illustrates the importance of collaborative partnerships and addressing the multi-faceted barriers from policy changes, and infrastructure readiness to the implementation of a radically new cervical screening program in communities. The paradigm shift in cervical cancer requires a monumental and concerted effort in educating both the healthcare providers and the general public. In this short review, we highlight how Pilot Project ROSE incorporated evidence-based tools that rapidly scaled up to Program ROSE. These ideas and solutions can be adapted and adopted by other countries. Notwithstanding the impact of COVID-19, it is incumbent on countries to pave the road towards the elimination of cervical cancer with pre-existing footpaths.
Fulltext Quality of Life vs. Supportive Care Needs for Oral Cancer Caregivers: Are They Related?

Ahmad AS, Doss JG, Ismail SM, Chen Kiong S, Jelon MA, Thangavalu L, et al.

Caregivers providing care for their family members with oral cancer usually endure the caregiving burden in silence, which affects their quality of life and necessitates the need for supportive care. The aim of this study is to determine the relationship between the quality of life (QOL) of oral cancer caregivers and their supportive care needs (SCN) in Malaysia. The Malaysian versions of the Caregiver Oncology Quality of Life Questionnaire (M-CarGOQoL) and the Comprehensive Needs Assessment Tool for Cancer Caregivers (M-CNAT-C) were self-administered by 56 family caregivers of oral cancer patients from five tertiary hospitals throughout Peninsular Malaysia and Sarawak between October and December 2021. Correlation and multiple regression analyses were employed, and the significance level was set at p < 0.05. The mean score for the QOL of caregivers was 76.16 ± 16.01, with the lowest scores in the psychological well-being (64.87 ± 30.12) and self-esteem (68.64 ± 28.29) domains. The mean score for SCN of caregivers was 36.42 ± 24.16, with the highest scores in the healthcare staff (58.44 ± 33.80) and information (55.35 ± 29.98) domains. The correlation between QOL and SCN was moderately inversed, (r(54) = 0.58, p < 0.01). There was a significant effect of caregiving duration (<3 h/day versus >3 h/day) on the combined dependent variables (QOL and SCN), F(2, 53) = 5.006, p < 0.01, partial η2 = 0.16. QOL and caregiving duration accounted for a significant 43% of SCN, R2 = 0.43, adjusted R2 = 0.41, F(2, 53) = 20.32, p < 0.01. In conclusion, oral cancer caregivers with poorer QOL have higher SCN. It is recommended that oral cancer caregivers be recognized by healthcare providers in order to deliver holistic patient care.
Fulltext Immune Biomarkers in Blood from Sarcoma Patients: A Pilot Study

Munisamy S, Radhakrishnan AK, Ramdas P, Samuel PJ, Singh VA

Curr Oncol, 2022 Aug 05;29(8):5585-5603.
PMID: 36005179 DOI: 10.3390/curroncol29080441

The main role of the host immune system is to identify and eliminate cancer cells, which is a complex process, but it is not a fail-safe mechanism. Many sarcoma patients succumb to this disease despite treatments rendered. The aim of this pilot study was to compare the levels of CD4+ T-cells, T-regulatory (Treg) cells, and cytokines such as tumor necrosis factor-alpha (TNF-α), interferon-gamma (IFN-γ), interleukin-17A (IL-17A), and transforming growth factor-beta-1 (TGF-β1) in peripheral blood leukocytes of sarcoma patients and healthy controls. For gene expression studies, total ribonucleic acid (RNA) was extracted from peripheral blood leukocytes and genes that were differentially regulated in peripheral blood leukocytes of sarcoma patients compared with healthy controls were determined using a commercial T-helper cell differentiation quantitative polymerase chain reaction (qPCR) array. Flow cytometer analysis was performed on blood samples from 26 sarcoma patients and 10 healthy controls to identify the levels of CD4+ T-cells and T-reg cells. The level of cytokines in plasma and culture supernatant were quantified using commercial enzyme-linked immunosorbent assay (ELISA) kits. A marked reduction in the percentage of CD4+ T-cells (p = 0.037) and levels of TNF-α (p = 0.004) and IFN-γ (0.010) was observed in sarcoma patients. Gene expression analysis showed five genes (homeobox A10 (HOXA10), GATA binding protein 3 (GATA3), prostaglandin D2 receptor 2 (PTGDR2), thymocyte selection associated high mobility group box (TOX), and C-C motif chemokine receptor 3 (CCR3)) were dysregulated (p < 0.05) in sarcoma patients. This study suggests that T-helper-1 immune responses are reduced in sarcoma patients.
