Abstract

It is well known that radiotherapy provides successful pain relief in bone metastases. Advancements in imaging and radiotherapy delivery technology have enabled safe delivery of higher dose radiotherapy, which will produce more durable tumor control. Over the last decades stereotactic radiosurgery (SRS), which delivers high dose radiation, has been successfully used for the treatment of intracranial lesions. The good results obtained in SRS have led to development of extra cranial stereotactic radiosurgery known as stereotactic ablative body radiotherapy (SABR). This review paper enlightens indication, target definition, efficacy and toxicity in spinal SABR.ABSTRAK Radioterapi telah terbukti sebagai modalitas yang dapat menghilangkan nyeri pada metastases tulang. Kemajuan dalam teknologi pencitraan dan pemberian radioterapi telah memungkinkan pemberian radioterapi dosis tinggi dengan aman, di mana hal ini dapat meningkatkan kontrol lokal. Selama dekade terakhir ini, stereotactic radiosurgery (SRS) yang memberikan radiasi dosis tinggi dinyatakan bermanfaat untuk tatalaksana berbagai kelainan intrakranial. Hasil cukup memuaskan yang diperoleh SRS mendorong untuk dikembangkan stereotactic radiosurgery ekstrakranial yang kemudian dikenal sebagai stereotactic ablative body radiotherapy (SABR). Tinjauan pustaka ini menjelaskan indikasi, target radiasi, efektivitas, dan efek samping pada prosedur SABR spinal.

Abstract

Cancer remains one of the largest contributors to the burden of health and mortality around the world. A study estimated 19.3 million new cases of cancer in the year 2020. GLOBOCAN 2020 provides a list of the most common cancers in the world which are prostate, lung, and colorectal cancers in men and breast, colorectal, and lung cancer in women. Naturally, different sociodemographic and geographic characteristics will cause disparities in these estimates. Since valid epidemiological data on cancer types in Indonesia remains unavailable, this study intended to provide data on the pattern of distribution of the 10 most common cancer types amongst various hospitals in Indonesia. This was achieved through the collection of registries and/or medical records that were obtained from March to September 2022. The data were then sorted and analyzed using SPSS 20.0. The resulting epidemiological data in multi-centers in Indonesia yielded a similar top 10 most common cancers trend with the GLOBOCAN 2020 worldwide incidence, although some differences were seen. A universal similarity that is found amongst different databases seems to be the prevalence of breast cancers, which always ‘champions’ all databases as the most common cancers among women. This provides a reflection for policy and decision makers for their prompt action to promote the prevention, diagnosis, and treatment of cancers in Indonesia, especially breast cancers.

Abstract

Treatment recommendations for cancer patients are carried out according to clinical assessment, type and stage of cancer and treatment guidelines. However, many patients do not accept the recommendations. This raises obstacles in managing of cancers, which not only affects the patients, but also the family and people around the patients. This problem could increase morbidity, mortality and recurrence rate, which might result in lower quality of life. Since this condition is a complex problem, there is necessity to explore and determine various determinants from different levels. The aim of this systematic  review was to explore the acceptances of cancer treatments among cancer patients and its associated determinants. Articles published from 2010 to 2023 were searched in four databases: ScienceDirect, Medline, Google Scholar and PubMed. Articles written in English and focussing on three main cancer treatments (surgery, chemotherapy and radiotherapy) were eligible.  A narrative approach was used and the data were analysed into selected themes. Data suggest that several factors influence patient acceptance for cancer therapy including sociodemographic, economic and spiritual cultural backgrounds; patient knowledge and perceptions; community support, as well as policy and availability of health facilities.  The determinants consist of individual, interpersonal, institutional, community and public policy level and interaction between levels are contributing to cancer treatment acceptance. In conclusion, cancer treatment acceptance remains a problem in particular in low middle income countries. In addition, the data on radiotherapy referral acceptance were limited and needed further study.

Abstract

Lung cancer patients in Indonesia exhibit a high prevalence of epidermal growth factor receptor (EGFR) mutations, with a substantial proportion attributed to rare or uncommon variants. The clinical significance of rare EGFR mutations lies in their differential sensitivity to tyrosine kinase inhibitors (TKIs). While they are frequently resistant to first- and second- generation TKIs, they often respond to third-generation TKIs, necessitating tailored treatment options. The need for improving access to advanced targeted therapies in Indonesia also highlights the importance of conducting research on rare EGFR mutations. The aim of this study was to identify the spectrum and frequency of EGFR mutations in patients with lung adenocarcinoma in Indonesia. A cross-sectional observational study with total sampling was conducted from January 2016 to April 2024 to investigate EGFR mutation profiles in lung adenocarcinoma patients. Samples were acquired from patients with a confirmed anatomical pathology diagnosis from various healthcare centers across Indonesia. A total of 4,778 samples were analyzed using real-time quantitative polymerase chain reaction (RT-qPCR) on various specimen types to determine EGFR mutation prevalence and patterns. Associations between demographic data and EGFR mutation status were assessed. EGFR mutations were detected in 54.6% of samples, with common mutations (exon 19 deletions/insertions and point mutation L858R) comprising 76.2% of positive cases and rare mutations (exon 20 insertions, point mutation G719X, S768I, T790M, and L861Q) accounted for 20.3%. Significant associations were found between geographic origin, age, and sex with EGFR mutation status. This study confirms substantial genetic variability and geographical differences in EGFR mutations among Indonesian lung adenocarcinoma patients, emphasizing the urgent need for further research to prompt enhanced molecular diagnostics and targeted therapies in the region.
