RESUMEN

BACKGROUND: Minimally invasive alternative approaches to treat non-melanoma skin cancers remain limited and unproven. OBJECTIVE: We aim to assess the efficacy of varying combinations of anti-tumor agents—imiquimod 5% cream, 5-fluorouracil 2% solution, and tretinoin 0.1% cream—with brief cryotherapy in treating non-melanoma skin cancers. METHODS: This retrospective study included 690 cases of non-melanoma skin cancers in 480 patients who received a diagnosis of a basal cell carcinoma or squamous cell carcinoma during a ten-year period. During treatment period, patients applied 30 applications of one of three combinations (imiquimod/tretinoin, 5-fluorouracil/tretinoin, or imiquimod/5-fluorouracil/tretinoin) and had cryotherapy every 2 weeks. Each patient had a clinical examination at least three years post-treatment or documented treatment failure. Clearance was defined by a lack of persistence or recurrence for 3 years following the completion of treatment. The likelihood of lesion clearance was evaluated using multivariable logistic regression analysis. RESULTS: A total of 186 cases (97; basal cell carcinoma and 89; squamous cell carcinoma) in 133 patients [37% women and 63% men; median (interquartile range) age, 77 (69, 83) years] met the inclusion criteria. Multivariable logistic regression analysis adjusting for clinical and lesion variables demonstrated that, relative to the imiquimod/5-fluorouracil/tretinoin treatment approach, imiquimod/ tretinoin (odds ratio, 0.05; 95% confidence interval, 0.00-0.99) and 5-fluorouracil/tretinoin (0.02; 0.00–0.45) were associated with lower likelihoods of lesion clearance. Likewise, morpheaform basal cell carcinoma had a lower probability of clearance (0.05; 0.00–0.72). CONCLUSIONS: The combination of imiquimod/5-fluorouracil/tretinoin with cryotherapy had high clearance rates and was the most effective treatment regimen.

RESUMEN

BACKGROUND: Knowledge regarding the inpatient burden of cutaneous squamous cell carcinoma (cSCC) is limited. OBJECTIVE: To provide nationally representative estimates for hospitalization characteristics due to cSCC and determine predictors for increased length of stay (LOS) and cost of care. METHODS/MATERIALS: A retrospective cohort study of the 2009 to 2015 National Inpatient Sample. Weighted multivariate logistic/linear regression models were created to evaluate sociodemographic factors associated with cSCC hospitalization and to assess characteristics associated with cost of care and LOS. RESULTS: This study included 15,784 cSCC and 255,244,626 non-SCC inpatients (prevalence = 6.2/100,000 inpatients). On average, cSCC hospitalizations lasted 5.8 days and cost $66,841.00. Cutaneous squamous cell carcinoma most often occurred on the scalp (30.57%), face (21.08%), and lower limb (11.93%). Controlling for all other factors, cSCC inpatients presented to larger/urban/teaching hospitals and were most often older non-Hispanic white women. More chronic conditions/diagnoses/procedures and nonwhite race were associated with greater cost of care and LOS. Cost of care and LOS significantly differed between cSCCs of different anatomical sites. The most common procedures performed were skin grafts (27.96%), excisions (25.83%), and lymph node biopsies (11.39%). CONCLUSION: This study highlights the substantial burden of inpatient cSCC in the United States. Further research is necessary to prevent cSCC hospitalizations and improve inpatient dermatologic care for cSCC.

RESUMEN

PURPOSE: To compare treatment costs and cost-effectiveness for transoral robotic surgery (TORS) and definitive intensity-modulated radiotherapy (IMRT) in managing early stage tonsil cancer. MATERIALS AND METHODS: Direct treatment costs for surgery and IMRT were calculated from SEER-Medicare data for a cohort with clinically early stage (cT1/2N0) p16+ tonsillar squamous cell carcinoma from Kaiser Permanente Southern California Health Plan between 2012 and 2017. A Markov decision tree model with a 5-year time horizon was then applied to the cohort which incorporated costs associated with treatment, surveillance, and recurrence. RESULTS: IMRT cost up to $19,000 more (35%) than TORS in direct treatment costs. When input into the Markov model, TORS dominated IMRT with lower cost and better effectiveness over a range of values. CONCLUSION: TORS is a more cost-effective treatment method than IMRT in early stage (cT1/2N0) tonsil cancer.

RESUMEN

INTRODUCTION: Single-fraction stereotactic radiosurgery (SRS) is delivered predominantly via two modalities: Gamma Knife, and linear accelerator (LINAC). Implementation of the American Tax Payer Relief Act (ATRA) in 2013 represented the first time limitations specifically targeting SRS reimbursement were introduced into federal law. The subsequent impact of the ATRA on SRS utilization in the United States (US) has yet to be examined. METHODS: The National Cancer Database from 2010-2016 identified brain metastases patients from non-small cell lung cancer throughout the US having undergone SRS. Utilization between GKRS and LINAC was assessed before (2010-2012), during (2013-2014) and after (2015-2016) ATRA implementation. RESULTS: In 2013, there was a substantial decrease of LINAC SRS in favor of GKRS in non-academic centers. Over the 3-year span immediately preceding ATRA implementation, 39% of all eligible SRS cases received LINAC. There was a modest decrease in LINAC utilization over the 2 years immediately following ATRA implementation (35%), followed by an increase over the next two years (40%). SRS modality showed differences over the three time periods (unadjusted, p = 0.043), primarily in non-academic centers (unadjusted, p = 0.003). CONCLUSIONS: ATRA implementation in 2013 caused an initial spike in Gamma Knife SRS utilization, followed by a decline to rates similar to the years before implementation. These findings indicate that the ATRA provision mandating Medicare reduction of outpatient payment rates for Gamma Knife to be equivalent with those of LINAC SRS had a significant short-term impact on the radiosurgical treatment of metastatic brain disease throughout the US, serving as a reminder of the importance/impact of public policy on treatment modality utilization by physicians and hospitals.

RESUMEN

BACKGROUND/OBJECTIVE: To describe the clinical settings in which keratinocyte cancers are excised in Queensland and describe the types of practitioners who excise them; to examine costs; and to identify predictors of hospital admission. METHODS: We used linked data for participants from the QSkin study (n = 43 794), including Medicare claims and Queensland hospital admissions relating to treatment episodes for incident keratinocyte cancers from July 2011 to June 2015. We used multinomial logistic regression to measure associations between demographic and clinical characteristics and treatment setting. The median costs of Medicare claims (AU$) were calculated. RESULTS: During 4 years of follow-up, there were 18 479 skin cancer excision episodes among 8613 people. Most excisions took place in private clinical rooms (89.7%), the remainder in hospitals (7.9% private; 2.4% public). Compared with other anatomical sites, skin cancers on the nose, eyelid, ear, lip, finger or genitalia were more likely to be treated in hospitals than in private clinical rooms (public hospital OR 5.7; 95%CI 4.5-7.2; private hospital OR 8.3; 95%CI 7.3-9.4). Primary care practitioners excised 83% of keratinocyte cancers, followed by plastic surgeons (9%) and dermatologists (6%). The median Medicare benefit paid was $253 in private clinical rooms and $334 in private hospitals. Out-of-pocket payments by patients treated in private hospitals were fourfold higher than those in private clinical rooms ($351 vs $80). CONCLUSIONS: Most keratinocyte cancers are excised in primary care, although more than 10% of excisions occur in hospital settings.

RESUMEN

Research advocates for the use of intensive, prophylactic swallowing therapy to help reduce the severity of dysphagia in patients receiving (chemo)radiotherapy ([C]RT) for head/neck cancer (HNC). Unfortunately, the intensity of this therapy, coupled with growing patient numbers and limited clinical resources, provides challenges to many international cancer facilities. Telepractice has been proposed as a potential method to provide patients with greater support in home-practice, whilst minimising burden to the health service. This study investigated the clinical and patient-attributable costs of delivering an intensive, prophylactic swallowing therapy protocol via a new telepractice application "SwallowIT" as compared to clinician-directed FTF therapy and independent patient self-directed therapy. Patients (n = 79) with oropharyngeal HNC receiving definitive (C)RT were randomised to receive therapy via a: clinician-directed (n = 26), patient-directed (n = 27), or SwallowIT-assisted (n = 26) model of care. Data pertaining to health service costs (service time, consumables, therapy resources), patient-attributable costs (travel and wages) and patient-reported health-related quality of life (QoL) (AQoL-6D) were collected. SwallowIT provided a cost-efficient model of care when compared to the clinician-directed model, with significant cost savings to both the health service and to HNC consumers (total saving of $1901.10 AUD per patient; p < 0.001). The SwallowIT model also proved more cost-effective than the patient-directed model, yielding clinically significantly superior QoL at the end of (C)RT, for comparable costs. Overall, when compared to the alternate methods of service-delivery, SwallowIT provided a financially viable and cost-effective method for the delivery of intensive, prophylactic swallowing therapy to patients with HNC during (C)RT.

RESUMEN

BACKGROUND: It is unknown whether treatment costs for keratinocyte carcinoma (KC) and actinic keratosis (AK) can be lowered by spending more on chemoprevention. OBJECTIVE: To examine the impact of 1-course treatment with topical fluorouracil (5-FU) on the face and ears on KC and AK treatment costs over 3 years. METHODS: The Veterans Affairs Keratinocyte Carcinoma Chemoprevention trial compared the efficacy of topical 5-FU 5% with that of vehicle control cream for reducing KC risk. Trial data and administrative data on costs and utilization were analyzed to measure postrandomization encounters and treatment costs for KC and AK care. Adjusted models were used to test for statistically significant differences between treatment arms for number of treatment encounters and costs. RESULTS: One year after randomization, the control arm had a higher mean number of treatment encounters for squamous cell carcinoma (0.04) than the intervention arm (0.01) (P < .01). At 1 year, the intervention arm had lower treatment and dermatologic costs: $2106 (standard deviation, $2079) compared with $2444 (standard deviation, $2716) for the control patients (P = .02). After 3 years, the intervention arm incurred a cost of $771 less per patient. LIMITATIONS: Care not provided or paid for by the Department of Veterans Affairs was not included. Results may not be generalizable to other payers. CONCLUSION: We found significant cost savings for patients treated with 5-FU.

RESUMEN

This retrospective study investigated the efficiency of nutritional support in unresectable locally advanced oesophageal squamous cell carcinoma (LAOSCC) patients who received concurrent chemoradiotherapy (CCRT) based on 5-fluorouracil and cisplatin. In the routine care group, 63 patients served as historical controls and received nutrition support in a reactive manner. In addition, 57 patients in the nutritional support group received timely diet counselling, oral nutritional supplements, enteral nutrition and/or parenteral nutrition during CCRT. This support was based on scores from nutritional risk screening 2002 (NRS-2002) after June 2014. The nutritional support group had significant advantages over the routine care group with respect to the incidence of neutropenia, the objective response rate, the change in serum albumin and the lengths of hospital stay. In addition, the nutritional support group had significantly higher levels of IgG and IL-2, higher proportions of NK, CD3+ and CD4+ cells as well as a higher ratio of CD4+ /CD8+ cells than the routine care group (p < .05). In contrast, the nutritional support group had a significantly lower level of IL-6. In conclusion, the current nutritional care programme could bring benefits of improving treatment compliance, reducing toxicity and lengths of hospital stay and enhancing the immune response.

RESUMEN

Solar ultraviolet (UV) radiation is the second most prevalent carcinogenic exposure in Canada and is similarly important in other countries with large Caucasian populations. The objective of this article was to estimate the economic burden associated with newly diagnosed non-melanoma skin cancers (NMSCs) attributable to occupational solar radiation exposure. Key cost categories considered were direct costs (healthcare costs, out-of-pocket costs (OOPCs), and informal caregiver costs); indirect costs (productivity/output costs and home production costs); and intangible costs (monetary value of the loss of health-related quality of life (HRQoL)). To generate the burden estimates, we used secondary data from multiple sources applied to computational methods developed from an extensive review of the literature. An estimated 2,846 (5.3%) of the 53,696 newly diagnosed cases of basal cell carcinoma (BCC) and 1,710 (9.2%) of the 18,549 newly diagnosed cases of squamous cell carcinoma (SCC) in 2011 in Canada were attributable to occupational solar radiation exposure. The combined total for direct and indirect costs of occupational NMSC cases is $28.9 million ($15.9 million for BCC and $13.0 million for SCC), and for intangible costs is $5.7 million ($0.6 million for BCC and $5.1 million for SCC). On a per-case basis, the total costs are $5,670 for BCC and $10,555 for SCC. The higher per-case cost for SCC is largely a result of a lower survival rate, and hence higher indirect and intangible costs. Our estimates can be used to raise awareness of occupational solar UV exposure as an important causal factor in NMSCs and can highlight the importance of occupational BCC and SCC among other occupational cancers.

RESUMEN

Cervical cancer is a leading cause of cancer death worldwide, with 85% of the disease burden residing in less developed regions. To inform evidence-based decision-making as cervical cancer screening programs are planned, implemented, and scaled in low- and middle-income countries, we used cost and test performance data from the START-UP demonstration project in Uganda and a microsimulation model of HPV infection and cervical carcinogenesis to quantify the health benefits, distributional equity, cost-effectiveness, and financial impact of either (1) improving access to cervical cancer screening or (2) increasing the number of lifetime screening opportunities for women who already have access. We found that when baseline screening coverage was low (i.e., 30%), expanding coverage of screening once in a lifetime to 50% can yield comparable reductions in cancer risk to screening two or three times in a lifetime at 30% coverage, lead to greater reductions in health disparities, and cost 150 international dollars (I$) per year of life saved (YLS). At higher baseline screening coverage levels (i.e., 70%), screening three times in a lifetime yielded greater health benefits than expanding screening once in a lifetime to 90% coverage, and would have a cost-effectiveness ratio (I$590 per YLS) below Uganda's per capita GDP. Given very low baseline coverage at present, we conclude that a policy focus on increasing access for previously unscreened women appears to be more compatible with improving both equity and efficiency than a focus on increasing frequency for a small subset of women.

RESUMEN

OBJECTIVES: To assess the cost-effectiveness of an educational intervention encouraging self-skin examinations for early detection of skin cancers among men older than 50 years. METHODS: A lifetime Markov model was constructed to combine data from the Skin Awareness Trial and other published sources. The model incorporated a health system perspective and the cost and health outcomes for melanoma, squamous and basal cell carcinomas, and benign skin lesions. Key model outcomes included Australian costs (2015), quality-adjusted life-years (QALYs), life-years, and counts of skin cancers. Univariate and probabilistic sensitivity analyses were undertaken to address parameter uncertainty. RESULTS: The mean cost of the intervention was A$5,298 compared with A$4,684 for usual care, whereas mean QALYs were 7.58 for the intervention group and 7.77 for the usual care group. The intervention was thus inferior to usual care. When only survival gain is considered, the model predicted the intervention would cost A$1,059 per life-year saved. The likelihood that the intervention was cost-effective up to A$50,000 per QALY gained was 43.9%. The model was stable to most data estimates; nevertheless, it relies on the specificity of clinical diagnosis of skin cancers and is subject to limited health utility data for people with skin lesions. CONCLUSIONS: Although the intervention improved skin checking behaviors and encouraged men to seek medical advice about suspicious lesions, the overall costs and effects from also detecting more squamous and basal cell carcinomas and benign lesions outweighed the positive health gains from detecting more thin melanomas.

RESUMEN

BACKGROUND: Thoracoscopic lobectomy for primary lung cancer has become increasingly popular worldwide due to several advantages over open lobectomy including reduced pain, reduced length of hospital stay, and comparable oncologic outcomes. The costs of thoracoscopic versus conventional open lobectomy have been compared in several studies with variable results. We compared the costs of thoracoscopic versus open lobectomy in lung cancer patients in Taiwan. METHODS: Patients who underwent lobectomy for primary lung cancer from the Taiwan National Health Insurance Research Database (NHIRD) between 2004 and 2010 were identified. Patient characteristics, operative data, and costs for each part of the hospitalization for surgery and 30 days of care after discharge were analyzed. RESULTS: A total of 5366 patients with complete clinical data who underwent either conventional open lobectomy (n = 3166, 59 %) or thoracoscopic lobectomy (n = 2200, 41 %) for primary lung cancer were identified from the database. Compared with open lobectomy, thoracoscopic lobectomy was associated with younger age, less comorbidity, shorter anesthesia times, and reduced lengths of hospital stay. Total hospital costs, operative costs, and other costs were significantly higher in the thoracoscopic group. The 30-day after discharge costs were significantly lower in the thoracoscopic group. CONCLUSIONS: Thoracoscopic lobectomy for primary lung cancer in Taiwan was associated with higher total hospital costs but lower 30 days after discharge costs than open lobectomy. These differences may have resulted from higher operative and instrument costs in the thoracoscopic group.

RESUMEN

PURPOSE: The objective of this study was to compare the cost associated with surgical versus interferon-alpha 2b (IFNα2b) treatment for ocular surface squamous neoplasia (OSSN). DESIGN: A matched, case-control study. PARTICIPANTS: A total of 98 patients with OSSN, 49 of whom were treated surgically and 49 of whom were treated medically. METHODS: Patients with OSSN treated with IFNα2b were matched to patients treated with surgery on the basis of age and date of treatment initiation. Financial cost to the patient was calculated using 2 different methods (hospital billing and Medicare allowable charges) and compared between the 2 groups. These fees included physician fees (clinic, pathology, anesthesia, and surgery), facility fees (clinic, pathology, and operating room), and medication costs. Time invested by patients was calculated in terms of number of visits to the hospital and compared between the 2 groups. Parking costs, transportation, caregiver wages, and lost wages were not considered in our analysis. MAIN OUTCOME MEASURES: Number of clinic visits and cost of therapy as represented by both hospital charges and Medicare allowable charges. RESULTS: When considering cost in terms of time, the medical group had an average of 2 more visits over 1 year compared with the surgical group. Cost as represented by hospital charges was higher in the surgical group (mean, $17 598; standard deviation [SD], $7624) when compared with the IFNα2b group (mean, $4986; SD, $2040). However, cost between the 2 groups was comparable when calculated on the basis of Medicare allowable charges (surgical group: mean, $3528; SD, $1610; medical group: mean, $2831; SD, $1082; P = 1.00). The highest cost in the surgical group was the excisional biopsy (hospital billing $17 598; Medicare allowable $3528), and the highest cost in the medical group was interferon ($1172 for drops, average 8.0 bottles; $370 for injections, average 5.4 injections). CONCLUSIONS: Our data in this group of patients previously demonstrated equal efficacy of surgical versus medical treatment. In this article, we consider costs of therapy and found that medical treatment involved two more office visits, whereas surgical treatment could be more or equally costly depending on insurance coverage.

RESUMEN

BACKGROUND: Skin cancer is a growing public health problem in South Africa due to its high ambient ultraviolet radiation environment. The purpose of this study was to estimate the annual health system costs of cutaneous melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) in South Africa, incorporating both the public and private sectors. METHODS: A cost-of-illness study was used to measure the economic burden of skin cancer and a 'bottom-up' micro-costing approach. Clinicians provided data on the patterns of care and treatments while national costing reports and clinician fees provided cost estimates. The mean costs per melanoma and per SCC/BCC were extrapolated to estimate national costs using published incidence data and official population statistics. One-way and probabilistic sensitivity analyses were undertaken to address the uncertainty of the parameters used in the model. RESULTS: The estimated total annual cost of treating skin cancers in South Africa were ZAR 92.4 million (2015) (or US$15.7 million). Sensitivity analyses showed that the total costs could vary between ZAR 89.7 to 94.6 million (US$15.2 to $16.1 million) when melanoma-related variables were changed and between ZAR 78.4 to 113.5 million ($13.3 to $19.3 million) when non-melanoma-related variables were changed. The primary drivers of overall costs were the cost of excisions, follow-up care, radical lymph node dissection, cryotherapy and radiation therapy. CONCLUSION: The cost of managing skin cancer in South Africa is sizable. Since skin cancer is largely preventable through improvements to sun-protection awareness and skin cancer prevention programs, this study highlights these healthcare resources could be used for other pressing public health problems in South Africa.

RESUMEN

BACKGROUND: The incidence of anal cancer in human immunodeficiency virus (HIV)-positive individuals is increasing, and how co-infection affects outcomes is not fully understood. This study sought to describe the current outcome disparities between anal cancer patients with and without HIV undergoing abdominoperineal resection (APR). METHODS: A retrospective review of all US patients diagnosed with anal squamous cell carcinoma, undergoing an APR, was performed. Cases were identified using a weighted derivative of the Healthcare Utilization Project's National Inpatient Sample (2000-2011). Patients greater than 60 years old were excluded after finding a skewed population distribution between those with and without HIV infection. Multivariable logistic regression and generalized linear modeling analysis examined factors associated with postoperative outcomes and cost. Perioperative complications, in-hospital mortality, length of hospital stay, and hospital costs were compared for those undergoing APR with and without HIV infection. RESULTS: A total of 1725 patients diagnosed with anal squamous cell cancer undergoing APR were identified, of whom 308 (17.9 %) were HIV-positive. HIV-positive patients were younger than HIV-negative patients undergoing APR for anal cancer (median age 47 years old versus 51 years old, p < 0.001) and were more likely to be male (95.1 versus 30.6 %, p < 0.001). Postoperative hemorrhage was more frequent in the HIV-positive group (5.1 versus 1.5 %, p = 0.05). Mortality was low in both groups (0 % in HIV-positive versus 1.49 % in HIV-negative, p = 0.355), and length of stay (LOS) (10+ days; 75th percentile of patient data) was similar (36.9 % with HIV versus 29.8 % without HIV, p = 0.262). Greater hospitalization costs were associated with patients who experienced a complication. However, there was no difference in hospitalization costs seen between HIV-positive and HIV-negative patients (p = 0.66). CONCLUSIONS: HIV status is not associated with worse postoperative recovery after APR for anal cancer as measured by length of stay or hospitalization cost. Further study may support APRs to be used more aggressively in HIV-positive patients with anal cancer.

RESUMEN

OBJECTIVES: Intensity-modulated radiotherapy (IMRT) is a dose-delivery technology allowing for a reduction in radiotherapy side effects. It has been rapidly adopted despite the lack of prospective studies showing improved outcomes. We sought to compare the cost through Medicare reimbursement patterns of surgery, IMRT, and conventional XRT in treating head and neck cancer. We then identified factors that correlate with these differences. METHODS: Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data were examined to determine treatment patterns for 47,237 patients with head and neck carcinoma from 2000 to 2007. We identified 14,748 patients that met our inclusion criteria. We then compared cost related to head and neck cancer treatments on the basis of Medicare payments. RESULTS: From 2000 to 2007, the usage of IMRT increased from 1.5% to 48.6% while the usage of conventional XRT decreased from 98.5% to 51.4% (p<0.0001). During this time, patients undergoing IMRT had a mean cost of $101,099 compared to $42,843 for XRT. For patients with early stage tumors, surgery alone cost $18,140, traditional XRT $32,296 while IMRT cost $95,047 (p<0.0001). When removing patients who underwent concomitant chemotherapy, patients treated with IMRT cost $67,576 compared to $24,955 for non-IMRT patients (p<0.0001). CONCLUSIONS: IMRT has become widely adopted as a primary treatment modality in head and neck cancer. We demonstrated that IMRT is significantly more costly than traditional treatment for head and neck cancers. Prospective studies investigating the comparative efficacy of IMRT will be needed in order to determine if this increased cost correlates with patient outcomes. LEVEL OF EVIDENCE: 2b.

RESUMEN

OBJECTIVE: To evaluate the cost-effectiveness of transoral robotic surgery (TORS) compared to intensity-modulated radiotherapy (IMRT) for early stage (T1-2, N0, M0) oropharyngeal squamous cell carcinoma (OPSCC). PATIENTS AND METHODS: A Markov decision tree model with a 5-year time horizon was developed. Comparative groups were: i) TORS with concurrent ipsilateral neck dissection +/- adjunctive IMRT, and ii) primary IMRT. Primary outcome was cost/quality adjusted life year (QALY). Perspective was the United States third party payer. Costs and effects were discounted at a rate of 3.5%. A threshold and probabilistic sensitivity analysis were performed. RESULTS: TORS strategy cost $30,992 and provided 4.81 QALYs/patient. The IMRT strategy cost $26,033 and provided a total of 4.78 QALYs/patient. The incremental cost effectiveness ratio for TORS vs. IMRT in the reference case was $165,300/QALY. The probability that TORS is cost-effective compared to IMRT at a maximum willingness-to-pay threshold of $50,000/QALY is 42%. CONCLUSION: An IMRT strategy for management of early stage OPSCC is more likely to be cost-effective compared to TORS. To improve the value of TORS for early stage OPSCC, consolidating TORS procedures to create high-volume centers of excellence may be a potential strategy to increase incremental effectiveness and reduce incremental costs.

RESUMEN

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in the United States. Cutaneous squamous cell carcinoma has an estimated incidence of more than 700,000 new cases per year and a 5% risk of metastasis. OBJECTIVE: To provide clinicians with guidelines for the management of cSCC based on evidence from a comprehensive literature review and consensus among the authors. MATERIALS AND METHODS: The authors conducted an extensive review of the medical literature on treatment methods for cSCC, taking into consideration cure rates, recurrence and metastatic rates, aesthetic and functional outcomes, and cost effectiveness of the procedures. RESULTS: Surgical treatments provide the best outcomes for cSCC. Mohs micrographic surgery is a cost-effective procedure that affords the highest cure rate, maximal tissue preservation, and superior cosmetic outcomes. Nonsurgical methods may be used as a primary treatment for low-risk squamous cell carcinomas, but the cure rates are lower. CONCLUSION: The cure rate remains the most important consideration in choosing the treatment method, but additional factors, such as the patient's general medical condition, psychosocial circumstances, the location of the tumor and cost effectiveness of the therapy should be considered. Mohs micrographic surgery remains the preferred treatment for high-risk tumors and tumors located in cosmetically sensitive areas.

RESUMEN

BACKGROUND: Skin cancer is one of the most common cancers in the world. The increased incidence of skin cancer, combined with limited health care resources and tight budgetary conditions, has increased the importance of understanding the economic impact of skin cancer. This research estimates the economic cost of skin cancer in the Australian state of New South Wales. METHOD: An incidence based approach is used to estimate lifetime costs of skin cancer. Both direct and indirect costs are considered - direct costs include resources associated with the management of skin cancer and indirect costs refer to productivity costs associated with morbidity and premature mortality. Diagnosis of skin cancer was determined according to ICD-10 codes using principal diagnosis. Linked administrative data and regression modelling are used to calculate costs; presented as Australian dollars for the year 2010. The human capital approach is used to value present and future productivity losses. RESULTS: The lifetime cost of the 150,000 incident cases of skin cancer diagnosed in NSW in 2010 is estimated at $536 million ($44,796 per melanoma and $2459 per non-melanoma). Direct costs accounted for 72 % of costs ($10,230 per melanoma and $2336 per non-melanoma) and indirect costs accounted for 28 % of costs ($34,567 per melanoma and $123 per non-melanoma). Direct costs are, on average, higher for females than males with indirect costs, on average, higher for males than females. CONCLUSION: This research provides new evidence on the economic cost of skin cancer and provides policy makers with information of the potential monetary savings that may arise from efforts to reduce the incidence of skin cancer.
