Incidence, cost and gender differences of oropharyngeal and noncervical anogenital cancers in South Korea.

BACKGROUND: Human papillomavirus (HPV) is associated with a significant public health burden, yet few studies have been conducted in Asia, especially on noncervical cancers. We estimated the incidence and cost of oropharyngeal and noncervical anogenital (anal, vulvar, vaginal, penile) cancer in Korea. METHODS: We conducted a retrospective cohort study using Korea's National Health Insurance (NHI) claim database from 2013 to 2016. The main outcome measures were the number of respective cancer incidences during the study period and the annual costs per patient in the first year after diagnosis, which was adjusted by relevant variables based on the regression analysis. RESULTS: During the study period, 8022 patients with these cancers were identified, and oropharyngeal cancer comprised 46% of them. The crude incidence rate for male oropharyngeal cancer was significantly higher than that of females (3.1 vs. 0.7 per 100,000 as of 2016, respectively). Additionally, the crude incidence of male oropharyngeal cancer increased from 2.7 in 2013 to 3.1 in 2016, whereas that of female and other cancers was stable during the study period. The mean annual incidence-based cost per patient in 2016 was highest for oropharyngeal cancers (21,870 USD), and it was significantly higher in males than in females based on then regression analysis (p < .001). CONCLUSIONS: Oropharyngeal cancer comprises the highest number of HPV-associated noncervical cancer incidences in Korea, and the incidence and cost of oropharyngeal cancer was significantly higher among males than females. More aggressive public health policy toward males may decrease gender gap of oropharyngeal cancer.

Cost-effectiveness of Common Diagnostic Approaches for Evaluation of Asymptomatic Microscopic Hematuria.

Importance: Asymptomatic microscopic hematuria (AMH) is highly prevalent and may signal occult genitourinary (GU) malignant abnormality. Common diagnostic approaches differ in their costs and effectiveness in detecting cancer. Given the low prevalence of GU malignant abnormality among patients with AMH, it is important to quantify the cost implications of detecting cancer for each approach. Objective: To estimate the effectiveness, costs, and incremental cost per cancer detected (ICCD) for 4 common diagnostic approaches evaluating AMH. Design, Setting, and Participants: A decision-analytic model-based cost-effectiveness analysis using inputs from the medical literature. PubMed searches were performed to identify relevant literature for all key model inputs, each of which was derived from the clinical study with the most robust data and greatest applicability. Analysis included adult patients with AMH on routine urinalysis with subgroups of high-risk patients (males, smokers, age ≥50 years) seen in the primary care or urologic referral setting. Interventions: Four diagnostic approaches were evaluated relative to the reference case of no evaluation: (1) computed tomography (CT) alone; (2) cystoscopy alone; (3) CT and cystoscopy combined; and (4) renal ultrasound and cystoscopy combined. Main Outcomes and Measures: At termination of the diagnostic period, cancers detected, costs (payer perspective), and ICCD per 10 000 patients evaluated for AMH. Results: Of the 4 diagnostic approaches analyzed, CT alone was dominated by all other strategies, detecting 221 cancers at a cost of $9 300 000. Ultrasound and cystoscopy detected 245 cancers and was most cost-effective with an ICCD of $53 810. Replacing ultrasound with CT detected just 1 additional cancer at an ICCD of $6 480 484. Ultrasound and cystoscopy remained the most cost-effective approach in subgroup analysis. The model was not sensitive to any inputs within the proposed ranges. Using probabilistic sensitivity analysis, ultrasound and cystoscopy was the dominant strategy in 100% of simulations. Conclusions and Relevance: The combination of renal ultrasound and cystoscopy is the most cost-effective among 4 diagnostic approaches for the initial evaluation of AMH. The use of ultrasound in lieu of CT as the first-line diagnostic strategy will optimize cancer detection and reduce costs associated with evaluation of AMH. Given our findings, we need to critically evaluate the appropriateness of our current clinical practices, and potentially alter our guidelines to reflect the most effective screening strategies for patients with AMH.

Cystectomy and urinary diversion is an excellent example for the growing complexity of the G-DRG (German diagnosis-related groups) system. Based on different diagnoses (malignant tumor of the urinary tract, benign disease of the urinary tract, malignant tumor of the female genital tract, or malignant tumor of the male genital tract), identical cases may lead to very different codes, resulting in even more differences in reimbursement.

Treatment for childhood rhabdomyosarcoma: the cost of cure.

Survival of children and young people with rhabdomyosarcoma has improved substantially during the past 30 years. The improvement can be attributed to the introduction of coordinated multimodality therapy through the efforts of collaborative clinical-trial groups in the USA and Europe. As survival has improved, important late sequelae of treatment have been characterised, and many relate to the local therapy used. Efforts have since been made by some groups to explore ways in which local treatment, particularly radiotherapy, can be omitted for some patients in an attempt to reduce the risk of late sequelae without compromising prospects for cure. An important issue is the overall cost of cure in relation to the treatment received and the need for better selection of patients most likely to benefit from this approach to therapy.

Follow-up surveillance strategies for genitourinary malignancies.

BACKGROUND: Genitourinary cancers account for more than 20% of all malignancies in the United States. These cancers do not usually yield rapid mortality, thereby necessitating longer-term surveillance strategies. METHODS: A review and analysis of relevant studies were performed. Follow-up strategies are proposed to reflect effective methods to detect recurrent prostate, bladder, renal, and testicular cancers. Cost analysis was performed using Medicare reimbursement rates. RESULTS: For genitourinary tumors, follow-up tests can be planned rationally based on detection rates and patterns. Tumor grade and stage drive follow-up strategies, along with therapeutic implications of detecting a recurrence. Symptomatic recurrences often obviate the need for radiographic tests and can minimize costs. Stage- specific plans for these four urologic malignancies are outlined specifically. CONCLUSIONS: Not all surveillance approaches have been critically tested for follow-up of genitourinary tumors, but ample data are available to propose sound medical and economic strategies.
