Abstract

Introduction: Cervical cancer screening coverage in Indonesia remains far below the WHO elimination target, because distance, lost wages, scarce female providers, and fragmented referral cause low participation and high triage attrition. We evaluated whether HPV-DNA self-sampling integrated with physician-led telemedicine triage improves screening completion and follow-up adherence and is cost-effective versus standard clinic-based screening. Methods: In a pragmatic, open-label, two-arm randomized controlled trial across two contrasting Indonesian regions—a dense metropolitan periphery (Region A) and a riverine/remote periphery (Region B)—1,032 under-screened women aged 30–50 years were randomized 1:1 to community-delivered HPV-DNA self-sampling with telemedicine triage of high-risk HPV (hrHPV)-positive results, or to standard referral for visual inspection with acetic acid or cytology. Primary outcomes were screening uptake within three months and the incremental cost-effectiveness ratio (ICER) per additional hrHPV case successfully triaged. Analysis followed intention-to-treat with multivariable logistic regression. Results: Screening uptake was 82.0% versus 48.1% (risk ratio 1.71, 95% CI 1.55–1.88; absolute difference 33.9%, number-needed-to-invite 3; adjusted odds ratio 4.94, 95% CI 3.72–6.56, p<0.001), consistent across regions (interaction p=0.42). Among hrHPV-positive women, follow-up adherence was 92.7% (38/41) versus 57.1% (12/21) (odds ratio 9.50, 95% CI 2.28–39.6, p=0.003), and CIN2+ was detected and treated in 11 versus 3 women. Cost per successful follow-up was US$315 versus US$516; the intervention was dominant in 96% of probabilistic simulations. Conclusion: Integrating HPV self-sampling with physician-led telemedicine triage substantially increased both screening and triage completion across diverse geographies while remaining cost-effective. National programs should embed telemedicine-supported triage to close the cervical-screening cascade.

Abstract

Background. Clinical autopsy is the only procedure that verifies antemortem diagnosis against pathological truth, yet in Indonesian tertiary hospitals refusal is the norm and neither its determinants nor its medicolegal consequences are quantified. Methods. This STROBE-reported retrospective cohort study analysed 324 consecutive adult in-hospital deaths across three tertiary referral hospitals in Palembang, South Sumatra, from 2019 to 2023. The primary outcome was next-of-kin refusal of autopsy consent; secondary outcomes were Goldman-class diagnostic discrepancy and time to correct diagnosis, censored at day 90. Proportions carry Wilson intervals; tests were checked against Monte-Carlo exact methods, ordinal exposures against trend tests and multiplicity against Benjamini-Hochberg. Results. Refusal was 84.0% (272/324; 95% CI 79.6-87.5) and did not differ across hospitals (p = 0.330). Javanese ethnicity carried the strongest association (94.3% versus 77.7%; OR 4.71, 95% CI 2.05-10.82), with monotonic gradients across education (trend z = -3.87, p < 0.001) and income (z = -2.84, p = 0.005) and refusal concentrated among the disadvantaged (Wagstaff index -0.312). Religious affiliation showed no association (p = 0.290; Cramér's V = 0.108). Any diagnostic discrepancy was commoner after refusal (61.4% versus 36.5%; OR 2.76, 95% CI 1.49-5.11), whereas the major-discrepancy contrast did not reach significance (26.1% versus 13.5%; OR 2.27, 95% CI 0.98-5.27; fragility index 1). Median time to correct diagnosis was 19 versus 5 days (p < 0.001). Conclusion. Autopsy refusal in Indonesia tracks ethnic mortuary practice and socioeconomic position rather than religious affiliation, redirecting policy towards ritual accommodation and mandatory mortality audit where consent is declined.

Abstract

Background: Nationally representative data on the heterogeneous malignancies managed in head and neck oncology remain limited in Indonesia. Objective: To estimate incidence, mortality, sex differences, and demographic change for six selected head and neck cancer site groups in Indonesia. Methods: We performed a descriptive secondary analysis of GLOBOCAN 2024 aggregate modeled estimates (version 08 July 2026). The definition included lip and oral cavity (C00–C06), salivary glands (C07–C08), oropharynx (C09–C10), nasopharynx (C11), hypopharynx (C12–C13), and larynx (C32). Counts and age-standardized rates were aggregated across mutually exclusive sites. Indonesia was compared descriptively with four reference populations. Constant-rate Cancer Tomorrow projections and two definitional sensitivity analyses were evaluated. Source uncertainty distributions were unavailable; therefore, confidence intervals were not constructed. Results: An estimated 28,226 cases and 16,025 deaths occurred in 2024; summed ASIR and ASMR were 8.91 and 5.06 per 100,000. Nasopharyngeal cancer contributed 16,064 cases (56.9%) and 8,718 deaths (54.4%). Male rates exceeded female rates: ASIR 13.19 versus 5.18 and ASMR 7.73 versus 2.77. With 2024 rates held constant, annual cases increased to 46,895 (+66.1%) and deaths to 27,900 (+74.1%) by 2050. All 21 validation checks passed. Conclusion: Indonesia's selected head and neck cancer burden is dominated by nasopharyngeal cancer and higher male rates. These modeled estimates support prevention, registry strengthening, and planning hypotheses but do not measure stage, utilization, treatment need, survival, cost, or causal effects.
