Does a family history of prostate cancer affect screening behavior in Jamaican men?

OBJECTIVE: To determine 1) the characteristics of males with a family history of prostate cancer who presented for screening and 2) the association between family history and diagnosis of prostate cancer in a cohort of screened Jamaican men. METHODS: The study consisted of a prospective cohort of black men who screened at the Jamaica Cancer Society in Kingston between 2006 and 2016. Data were collected on: 1) age at screening and age at diagnosis of prostate cancer, 2) family history of prostate cancer, and 3) prostate-specific antigen (PSA) and digital rectal examination (DRE) findings. RESULTS: Approximately 600 (21.4%) of screened men who reported data on family history (2 791 / 2 867) said they had a family history of prostate cancer. Men with a family history of prostate cancer 1) commenced screening at a younger age than men without a family history (P <0.001) and 2) tended to have a younger age at diagnosis of prostate cancer (P = 0.262). There was no significantly increased risk of prostate cancer in men with a reported family history of prostate cancer (odds ratio: 1.4; 95% confidence interval: 0.821-2.386; P = 0.217). CONCLUSIONS: Men with a family history of prostate cancer presented frequently for screening and earlier than those without. There was a lack of association between family history of prostate cancer and diagnosis. Further studies are needed to investigate this association and validate family histories.

Prostate Cancer Knowledge, Prevention, and Screening Behaviors in Jamaican Men.

Screening is the only effective method of reducing prostate cancer mortality. Several reports have documented poor prostate cancer awareness and screening practices in Jamaican men. The Jamaica Cancer Society provides the most organized and largest form of screening in Jamaica and hosts an annual mass screening clinic on Prostate Cancer Awareness Day in September. We sought to determine the knowledge and attitudes towards screening and risks and prevention of prostate cancer. The study represented a cross-sectional analysis of 55 men presenting for screening on Prostate Cancer Awareness Day, September 2014 in Kingston, Jamaica. Information on prostate cancer knowledge and attitudes towards screening was obtained using interviewer-administered questionnaires (The Integrative Model of Prostate Cancer Disparity (PIPCaD). Prostate specific antigen (PSA) and digital rectal examination (DRE) were obtained from all patients. Mean PSA of participating men was 1.5 ± 1.48 ng/ml. Fifteen percent of men surveyed had a family history of prostate cancer. Prostate cancer knowledge was moderate, with at least 84 % of men responding correctly to 5 of 10 questions referring to prostate cancer risk and prevention. Most men had a favorable attitude towards screening. Starch formed the major portion of the diet in 68 % of men and 35 % of men engaged in no physical activity. Jamaican men surveyed have moderate prostate cancer knowledge and a positive attitude towards screening and prostate cancer prevention activities. However, the application of activities for potential prevention of modifiable risk factors is poor.

Overactive bladder in adults with sickle cell disease.

AIMS: To characterize the prevalence and impact of nocturnal enuresis and overactive bladder (OAB) symptomatology in the adult sickle-cell disease (SCD) population. METHODS: We performed a single-center, cross-sectional study of adult SCD patients from October 2012 to February 2014, using the validated Pfizer OAB short form questionnaire and brief voiding history surveys. Patient responses and scores were compared to that of controls having normal or sickle cell trait hemoglobin genotypes. RESULTS: A group of 239 SCD patients (116 males, 123 females) were compared with 104 normal and 57 sickle cell trait patients. Seven of 239 (2.9%) SCD patients compared to none of the 161 patients without SCD (P = 0.04) reported current nocturnal enuresis. The median age of nocturnal enuresis cessation was higher in SCD patients (12.0, IQR 9.0-15.0 years) compared to that of both normal (7.5, IQR 6.0-9.8 years) and sickle cell trait (7.5, IQR 6.0-8.8 years) groups (P < 0.0001). Ninety-three of 239 (38.9%) SCD patients compared to 17 of 104 (16.3%) normal and 11 of 57 (19.3%) sickle cell trait had scores indicating OAB symptomatology (P < 0.0001). Patients with SCD had higher OAB symptom severity and lower health-related quality of life (HRQL) scores compared to the normal and sickle cell trait groups (P < 0.0001 and P < 0.0001, respectively). CONCLUSIONS: We demonstrate an elevated rate of nocturnal enuresis and OAB symptoms in the adult SCD population. An OAB phenotype may be an under-recognized complication of SCD irrespective of age.

Pathological outcome and biochemical recurrence-free survival after radical prostatectomy in African-American, Afro-Caribbean (Jamaican) and Caucasian-American men: an international comparison.

OBJECTIVE: To compare pathological and biochemical outcomes of radical prostatectomy (RP) among African-American (AA), Afro-Caribbean (AC; Jamaican) and Caucasian-American (CA) men using an international cohort of patients who underwent RP in the USA and Jamaica. MATERIALS AND METHODS: A retrospective review was performed of men who underwent RP for clinically organ-confined (OC) prostate cancer between 2000 and 2011 at Columbia University Medical Center (New York, USA) and the University Hospital of the West Indies (Kingston, Jamaica) between 2000 and 2007. Men who had received neoadjuvant or adjuvant (within 3 months) therapy were excluded. Clinicopathological variables were compared among the three groups, focusing on age, stage, PSA level, Gleason sum (GS) and margin status. Multivariate analysis was performed to determine the predictors of biochemical recurrence (BCR; PSA >0.2 ng/mL), and Kaplan-Meier analysis was performed to determine BCR-free survival rates in AA, AC and CA men. RESULTS: A total of 483 men underwent RP for clinically OC disease (CM, n = 309, AA, n = 93 and AC, n = 81). The mean patient age was 59 years, with AA men being younger than CA men (58 vs 60 years, P< 0.05). The mean (range) follow-up was 49 (13-133) months with no significant difference among the groups. The men in the AC cohort had a higher mean PSA level than AA and CA men (8.8 vs 6.2 and 5.0 ng/mL, respectively, P< 0.05) and more clinical GS ≥7 (44%) tumours than AA (8%) and CA men (0%; P< 0.01). On multivariate analysis, controlling for stage, grade, PSA level and margins, AA and AC race were independent predictors of BCR. AA and AC men had significantly lower 5-year BCR-free survival (76 and 74%, respectively) than CA men (98% [P < 0.001]). CONCLUSIONS: This international comparison of clinicopathological outcomes in AA, AC and CA men undergoing RP shows that AA and AC men present similarly with more aggressive disease features than CA men and have lower 5-year BCR-free survival. Both AA and AC race are significant predictors of BCR, independently of stage, grade, PSA level and margin status. Further research is needed to elucidate and correct the mechanisms behind the observed difference in outcome among these populations.

Stuttering priapism: insights into pathogenesis and management.

Priapism is defined as a persistent, painful erection that continues beyond, or is unrelated to, sexual stimulation. It may be categorized as either ischemic (low/absent flow) or nonischemic (high flow). Stuttering priapism is a variant of the ischemic type that is characterized by repetitive, transient, painful, self-limiting episodes of priapism. It is associated with various hematological disorders, including sickle cell disease and pharmacological treatments. The consequences of ineffective treatment of priapism are erectile dysfunction and impaired quality of life due to chronic pain and physical disfigurement. Many of the existing medical therapeutic options for treatment of stuttering priapism are nonmechanistic and associated with significant adverse effects. However, the scientific knowledge of stuttering priapism has transitioned in the past few years, from a condition that is poorly understood to one that has borne a burst of evolving molecular science. In this review, the pathophysiology of priapism is discussed, with particular emphasis on new molecular effectors and mechanisms. Novel treatment methods, as well as potential future agents, based on the emerging molecular evidence are discussed.

Impact of the National Health Fund policy on hormone treatment for prostate cancer in Jamaica.

OBJECTIVE: To compare the proportion of patients choosing surgical versus medical castration to treat prostate cancer, before and after the National Health Fund (NHF) of Jamaica began to subsidize hormone therapy. METHODS: A retrospective review was performed at the University Hospital of the West Indies (UHWI), Jamaica. The pathology database at UHWI was searched to identify patients who had prostate biopsies between January 2000 and December 2007. These were combined with records of biopsies at external institutions. Medical records of all patients with positive prostate biopsies were reviewed to determine if they had received androgen deprivation therapy (ADT). Patients were classified as having had surgical castration (bilateral orchiectomy) or medical castration. Chi-square statistics were used to determine the difference in proportions between those choosing medical versus surgical castration before and after March 2005, when the NHF began offering subsidies for ADT drugs. RESULTS: Of the 1,529 prostate biopsies performed during the study period, 680 (44.0%) cases of prostate cancer were diagnosed. Of these, 458 patients underwent ADT and had complete records available for analysis. The mean patient age was 72 years. During the entire study period, surgical castration was performed in 265 patients (58.0%) and medical castration in 193 (42.0%). A greater proportion of orchiectomies were performed before March 2005, rather than after (P < 0.001). Estrogens were the most common method of medical castration used before the NHF subsidy became available (62.0%); while luteinizing hormone-releasing hormone analogues (38.0%) and antiandrogens (36.5%) were most often chosen afterwards. CONCLUSIONS: Surgical castration was more common than medical castration before March 2005. After the NHF began to subsidize the cost of drugs for hormone therapy, medical castration was chosen more often. Increased access to drugs for hormone therapy has changed treatment patterns in Jamaica.

External validation of the priapism impact profile in a Jamaican cohort of patients with sickle cell disease.

BACKGROUND: Priapism impairs quality of life and has a predilection for males with sickle cell disease (SCD). The Priapism Impact Profile (PIP) is a novel 12-item instrument designed to measure general health-related impact of priapism. The aim of the study was to evaluate the validity and reliability of the PIP in a Jamaican cohort of SCD patients experiencing priapism. METHODS: One hundred SCD patients with a history of priapism were recruited from a sickle cell clinic in Kingston, Jamaica and administered the PIP questionnaire. Patients rated each item of the PIP for clarity and importance. Statistical testing was employed to evaluate the psychometric performance of the PIP. Content validation was assessed based on patient descriptive rating of the items based on clarity, and importance and criterion-oriented validity were assessed by evaluating the PIP's ability to distinguish between patient subgroups. Test-retest repeatability was assessed in 20 of the 100 patients. RESULTS: Patients were stratified into active (54) and remission (46) priapism groups based on their experience of priapism within the past year. Patients in the active priapism group were younger (p = 0.011), had a shorter duration of disease (p = 0.023), and had more frequent priapism episodes (p = 0.036) than the remission group. PIP questionnaire scores differed significantly with respect to priapism activity (p < 0.001) and prevalence of erectile dysfunction (p < 0.05) but not by priapism severity (p = 0.62). The PIP questionnaire had good content validity, with questions rated as having medium or high clarity and importance by an average of 82.8% and 69.2% of patients, respectively. CONCLUSION: The PIP questionnaire was successfully validated in a Jamaican cohort of SCD patients and adequately discriminated patients with active priapism from those in remission. The instrument may be utilized in routine clinical management of patients with SCD-associated priapism. Further clinical investigations are warranted in other populations.

Pathological upgrading and upstaging at radical prostatectomy in Jamaican men with low-risk prostate cancer.

Several studies suggest race-based health disparities in men with low-risk prostate cancer (PCa), with African American males having poorer oncological outcomes. We sought to determine the prevalence and predictors of pathological upgrading and upstaging in Jamaican men with low-risk PCa treated with radical prostatectomy (RP). Data on 141 men who met the National Comprehensive Cancer Network criteria for low-risk PCa and underwent RP at a single institution were reviewed. All men had a transrectal ultrasound-guided biopsy. Pre-operative clinical and final pathological data were obtained. Data were summarised as means and standard deviations or percentages as appropriate. Bivariate analyses such as independent samples t-tests and chi-square tables were conducted and logistic regression models were estimated to predict upgrading (>Gleason 6) and upstaging (p ≥ T3). The mean age was 59.5 ± 7.8 years with mean prostate specific antigen (PSA) of 6.6 ± 2 ng/mL. A total of 48.3% of men were upgraded and 11.4% were upstaged. Bivariate analyses indicated that PSA (p = 0.008) and percentage positive cores (p = 0.002) were associated with upgrading. PSA (p = 0.042) and percentage positive cores (p = 0.003) were significantly associated with upstaging. The odds of upgrading increased with increased PSA levels (OR 1.40, 95% CI 1.05-1.87, p = 0.021) or increased percentage positive cores (OR 8.27, 95% CI 2.19-31.16, p = 0.002). The odds of upstaging increased with increased PSA levels (OR 1.4, 95% CI 1.01-1.96, p = 0.046) and with increased percentages positive cores (OR 11.4; 95% CI 2.06-63.09, p = 0.005). Jamaican men with low-risk PCa are at high risk of pathological upgrading and upstaging at RP. These findings should be taken into consideration when discussing treatment options with these patients.

Evaluation of sexual and fertility dysfunction in spinal cord-injured men in Jamaica.

INTRODUCTION: Sexual dysfunction and infertility are common in males with traumatic spinal cord injuries (SCIs). The objective of this study was to determine the prevalence of sexual dysfunction and infertility in males with traumatic SCI managed in Jamaica, as well as the therapeutic options offered. CASE PRESENTATION: A cross-sectional study including males with traumatic SCI managed at the Sir John Golding Rehabilitation Centre, Kingston, Jamaica was carried out between 1 January and 31 December 2015. Sexual function was measured with the International Index of Erectile Function Questionnaire, and further information on social history, fertility desires and treatment options offered were collected. Data were analyzed using Stata 12 for Windows (College Station, TX, USA). The mean age of patients at the time of study was 38.8±15.3 years (range 19-71) with a mean duration of injury of 3.7±2.4 years (range 1.3-15.6). Of 45 patients with traumatic SCI surveyed, 90.7% had erectile dysfunction, with 62.8% being classified as severe and 73.3% of men were unable to ejaculate. Treatment for erectile and ejaculatory dysfunction was offered in only two patients, respectively. Most (71.1%) patients indicated that they wanted to have children in the future, however, no one had been referred for assisted reproductive techniques. DISCUSSION: Men with traumatic SCI have high rates of severe erectile and ejaculatory dysfunctions, but have preserved interests in maintaining fertility. Adherence to guidelines for sexual education for men with traumatic SCI in Jamaica and the Caribbean is needed.

Prostate Cancer Screening in Jamaica: Results of the Largest National Screening Clinic.

Prostate cancer is highly prevalent in Jamaica and is the leading cause of cancer-related deaths. Our aim was to evaluate the patterns of screening in the largest organized screening clinic in Jamaica at the Jamaica Cancer Society. A retrospective analysis of all men presenting for screening at the Jamaica Cancer Society from 1995 to 2005 was done. All patients had digital rectal examinations (DRE) and prostate specific antigen (PSA) tests done. Results of prostate biopsies were noted. 1117 men of mean age 59.9 ± 8.2 years presented for screening. The median documented PSA was 1.6 ng/mL (maximum of 5170 ng/mL). Most patients presented for only 1 screen. There was a gradual reduction in the mean age of presentation for screening over the period. Prostate biopsies were requested on 11% of screening visits; however, only 59% of these were done. 5.6% of all persons screened were found to have cancer. Of the cancers diagnosed, Gleason 6 adenocarcinoma was the commonest grade and median PSA was 8.9 ng/mL (range 1.5-1059 ng/mL). Older men tend to screen for prostate cancer in Jamaica. However, compliance with regular maintenance visits and requests for confirmatory biopsies are poor. Screening needs intervention in the Jamaican population.

Molecular pathophysiology of priapism: emerging targets.

Priapism is an erectile disorder involving uncontrolled, prolonged penile erection without sexual purpose, which can lead to erectile dysfunction. Ischemic priapism, the most common of the variants, occurs with high prevalence in patients with sickle cell disease. Despite the potentially devastating complications of this condition, management of recurrent priapism episodes historically has commonly involved reactive treatments rather than preventative strategies. Recently, increasing elucidation of the complex molecular mechanisms underlying this disorder, principally involving dysregulation of nitric oxide signaling, has allowed for greater insights and exploration into potential therapeutic targets. In this review, we discuss the multiple molecular regulatory pathways implicated in the pathophysiology of priapism. We also identify the roles and mechanisms of molecular effectors in providing the basis for potential future therapies.

Testosterone Replacement Therapy in Adolescents With Sickle Cell Disease Reverses Hypogonadism Without Promoting Priapism: A Case Report.

Delayed puberty secondary to hypogonadism is commonly seen in sickle cell disease (SCD), affecting normal growth and development. The condition is rarely treated in SCD for fear of inducing priapism episodes. We present a case report of an Afro-Jamaican adolescent male at 16 years of age who presented with symptoms of delayed puberty as well as frequent stuttering priapism episodes. Endocrinological assessment revealed low serum total testosterone levels. Treatment was commenced monthly with testosterone enanthate which resulted in improved symptoms of delayed puberty, improvement in anthropometric parameters while apparently ameliorating priapism episodes.

A delayed foreskin-sparing approach to the management of penile fractures in uncircumcised Jamaican men.

INTRODUCTION: The traditional surgical approach to penile fracture is to perform a circumferential subcoronal degloving incision emergently to repair the injury. This approach necessitates circumcision to avoid foreskin complications. We present four men who had a delayed foreskin-sparing approach and discuss its advantages. PRESENTATION OF CASE: Four of five uncircumcised patients who had suspected penile fractures secondary to coital injury, and without suspicion of concomitant urethral injury, had a delayed exploration, seven days after injury, utilizing an incision directly over the palpable haematoma, at the location of the tunical defect, thereby resulting in foreskin preservation. Two of 5 patients had repair under general anaesthesia, one under local anaesthesia and surgery was cancelled in another because upon reassessment at seven days he had normal erections and a normal penile examination. At follow up, all men had good functional and cosmetic outcomes. DISCUSSION: Uncircumcised patients with penile fractures, without suspicion of urethral injury, may undergo a delayed repair without prophylactic circumcision since there is minimal risk of foreskin complications. Delayed repair decreases the incidence of negative explorations by fostering a conservative approach in mimicking conditions such as superficial vein lacerations. It also enables the use of local anaesthesia in an elective ambulatory setting. CONCLUSION: Delayed repair of penile fractures results in foreskin preservation, facilitates elective ambulatory care under local anaesthesia and decreases the incidence of negative surgical explorations.

Is testosterone deficiency a possible risk factor for priapism associated with sickle-cell disease?

PURPOSE: The purpose of this study was to determine the association of testosterone deficiency and priapism in adult men with sickle cell disease (SCD). METHODS: A cross-sectional study of 50 adult men with SCD (hemoglobin SS) was performed. All patients had early morning blood taken for total and free testosterone, FSH, LH, prolactin, lipid levels, LDH and hematological indices. Patients completed an interviewer-administered questionnaire regarding priapism frequency, duration and treatment. Testosterone deficiency was defined as a serum total testosterone<12 nmol/L (346 ng/dL). RESULTS: The mean age of the study population was 34.2±8.9 years. Priapism was noted in 24 (48%) patients and was most frequently seen in men between ages 18-25 years. Testosterone deficiency was observed in 11 of the 50 (22%) patients, particularly in 6 of 24 (25%) patients with histories of priapism. There was no difference in mean total testosterone levels in patients with and without a history of priapism (16.7±4.9 nmol/L and 15.4±5.9 nmol/L, respectively) (p=0.43). Similarly, there was no difference in serum LH and FSH levels based on history of priapism. CONCLUSION: Testosterone deficiency is prevalent in patients with SCD; however, we did not identify an association based on a history of priapism. Larger, prospectively gathered data are needed to define the priapism profile of SCD patients with testosterone deficiency.

Current state of prostate cancer treatment in Jamaica.

Prostate cancer is the commonest cancer in Jamaica as well as the leading cause of cancer-related deaths. One report suggested that Jamaica has the highest incidence rate of prostate cancer in the world, with an age-standardised rate of 304/100,000 per year. The Caribbean region is reported to have the highest mortality rate of prostate cancer worldwide. Prostate cancer accounts for a large portion of the clinical practice for health-care practitioners in Jamaica. The Jamaica Urological Society is a professional body comprising 19 urologists in Jamaica who provide most of the care for men with prostate cancer in collaboration with medical oncologists, radiation oncologists, and a palliative care physician. The health-care system is structured in two tiers in Jamaica: public and private. The urologist-to-patient ratio is high, and this limits adequate urological care. Screening for prostate cancer is not a national policy in Jamaica. However, the Jamaica Urological Society and the Jamaica Cancer Society work synergistically to promote screening as well as to provide patient education for prostate cancer. Adequate treatment for localised prostate cancer is available in Jamaica in the forms of active surveillance, nerve-sparing radical retropubic prostatectomy, external beam radiation, and brachytherapy. However, there is a geographic maldistribution of centres that provide prostate cancer treatment, which leads to treatment delays. Also, there is difficulty in affording some treatment options in the private health-care sectors. Androgen deprivation therapy is available for treatment of locally advanced and metastatic prostate cancer and is subsidised through a programme called the National Health Fund. Second-line hormonal agents and chemotherapeutic agents are available but are costly to most of the population. The infrastructure for treatment of prostate cancer in Jamaica is good, but it requires additional technological advances as well as additional specialist services.

Does a family history of prostate cancer affect screening behavior in Jamaican men?

[ABSTRACT]. Objective. To determine 1) the characteristics of males with a family history of prostate cancer who presented for screening and 2) the association between family history and diagnosis of prostate cancer in a cohort of screened Jamaican men.

Não se observou risco significativamente maior de câncer de próstata nos homens com história familiar informada de câncer de próstata (odds ratio 1,4; intervalo de confiança de 95% 0,821-2,386; P = 0,217). Conclusões Os homens com história de câncer de próstata buscaram com frequência fazer o rastreamento e a uma idade mais jovem em relação aos homens sem história familiar. Observou-se a ausência de associação entre história familiar e diagnóstico de câncer de próstata. Outros estudos são necessários para investigar esta associação e validar as histórias familiares.

Priapism in hematological and coagulative disorders: an update.

Priapism is a true urological emergency that is typified by a persistent and painful erection. High-risk groups include patients with hematological or coagulative disorders; for example, those with sickle cell disease, leukemia or glucose-6-phosphate dehydrogenase deficiency. The diagnosis for priapism must be made urgently using patient history, physical examination and blood gas findings on corporal aspiration. Emergency treatment is needed to avoid erectile dysfunction. However, in high-risk groups, prophylaxis must be encouraged. A number of prophylactic measures are emerging based on progress in the understanding of the pathophysiology of priapism in these particular patients. In this Review, priapism as it relates to hematological disorders is discussed, focusing on treatment and prophylaxis.

Bone mineral density in Jamaican men on androgen deprivation therapy for prostate cancer.

BACKGROUND: Androgen deprivation therapy (ADT) has been reported to reduce the bone mineral density (BMD) in men with prostate cancer (CaP). However, Afro-Caribbeans are under-represented in most studies. The aim was to determine the effect of androgen deprivation therapy (ADT) on the bone mineral density (BMD) of men with prostate cancer in Jamaica. METHODS: The study consisted of 346 Jamaican men, over 40 years of age: 133 ADT treated CaP cases (group 1), 43 hormone-naïve CaP controls (group 2) and 170 hormone naïve controls without CaP (group 3). Exclusion criteria included metastatic disease, bisphosphonate therapy or metabolic disease affecting BMD. BMD was measured with a calcaneal ultrasound and expressed in S.D. units relative to young adult men (T score), according to the World Health Organization definition. Patient weight, height and BMI were assessed. RESULTS: Mean ± sd, age of patients in group 1 (75± 7.4 yrs) was significantly greater than groups 2 and 3 (67 ± 8.1 yrs; 65±12.0 yrs). There was no significant difference in weight and BMI between the 3 groups. . The types of ADT (% of cases, median duration in months with IQR) included LHRH (Luteinizing hormone releasing hormone) analogues (28.6%, 17.9, IQR 20.4), oestrogens (9.8%, 60.5, IQR 45.6) anti-androgens (11.3%, 3.3, IQR 15.2) and orchiectomy (15.7%, 43.4, IQR 63.9). Unadjusted t score of group 1, mean ± sd, (-1.6± 1.5) was significantly less than group 2 (-0.9±1.1) and group 3 (-0.7±1.4), p <0.001. Ninety three (69.9%), 20 (45%) and 75 (42%) of patients in groups 1, 2 and 3 respectively were classified as either osteopenic or osteoporotic (p<0.001). Adjusting for age, there was a significant difference in t scores between groups 1 and 2 as well as between groups 1 and 3 (p<0.001). Compared with oestrogen therapy and adjusting for duration of therapy, the odds of low bone mineral density (osteopenia or osteoporosis) with LHRH analogue was 4.5 (95%CI, 14.3 to 3.4); with anti-androgens was 5.9 (95%CI, 32.7 to 5); with orchiectomy was 7.3 (95%CI, 30 to 5.8) and multiple drugs was 9.2 ((95%CI, 31 to 7.1). CONCLUSIONS: ADT is associated with lower BMD in Jamaican men on hormonal therapy for prostate cancer.

Impact of the National Health Fund policy on hormone treatment for prostate cancer in Jamaica / Repercusión de un subsidio del Fondo Nacional de Salud en la hormonoterapia para el cáncer de próstata en Jamaica

OBJECTIVE: To compare the proportion of patients choosing surgical versus medical castration to treat prostate cancer, before and after the National Health Fund (NHF) of Jamaica began to subsidize hormone therapy. METHODS: A retrospective review was performed at the University Hospital of the West Indies (UHWI), Jamaica. The pathology database at UHWI was searched to identify patients who had prostate biopsies between January 2000 and December 2007. These were combined with records of biopsies at external institutions. Medical records of all patients with positive prostate biopsies were reviewed to determine if they had received androgen deprivation therapy (ADT). Patients were classified as having had surgical castration (bilateral orchiectomy) or medical castration. Chi-square statistics were used to determine the difference in proportions between those choosing medical versus surgical castration before and after March 2005, when the NHF began offering subsidies for ADT drugs. RESULTS: Of the 1 529 prostate biopsies performed during the study period, 680 (44.0 percent) cases of prostate cancer were diagnosed. Of these, 458 patients underwent ADT and had complete records available for analysis. The mean patient age was 72 years. During the entire study period, surgical castration was performed in 265 patients (58.0 percent) and medical castration in 193 (42.0 percent). A greater proportion of orchiectomies were performed before March 2005, rather than after (P < 0.001). Estrogens were the most common method of medical castration used before the NHF subsidy became available (62.0 percent); while luteinizing hormone-releasing hormone analogues (38.0 percent) and antiandrogens (36.5 percent) were most often chosen afterwards. CONCLUSIONS: Surgical castration was more common than medical castration before March 2005. After the NHF began to subsidize the cost of drugs for hormone therapy, medical castration was chosen more often. Increased access to drugs for hormone therapy has changed treatment patterns in Jamaica.

OBJETIVO: Comparar la proporción de pacientes que eligen la castración quirúrgica frente a la castración farmacológica para tratar el cáncer de próstata, antes y después de la creación de un subsidio del Fondo Nacional de Salud (NHF, por sus siglas en inglés) de Jamaica destinado a cubrir los costos de la hormonoterapia. MÉTODOS: Se llevó a cabo un examen retrospectivo en el Hospital Universitario de las Indias Occidentales, Jamaica. Se efectuó una búsqueda en la base de datos de enfermedades de dicho hospital para identificar a los pacientes a quienes se les había practicado una biopsia de próstata entre enero del 2000 y diciembre del 2007. Los datos se combinaron con los registros de biopsias llevadas a cabo en instituciones externas. Se estudiaron las historias clínicas de todos los pacientes con resultados positivos en la biopsia de próstata para determinar si habían recibido tratamiento de supresión androgénica. Los pacientes se clasificaron en dos grupos, según se hubieran tratado mediante castración quirúrgica (orquiectomía bilateral) o farmacológica. Se usó la prueba de la ji al cuadrado para determinar la diferencia en las proporciones entre los pacientes que escogieron la castración quirúrgica y los que escogieron la opción farmacológica antes y después de marzo del 2005, la fecha en la que el NHF empezó a subsidiar los medicamentos de supresión androgénica. RESULTADOS: Entre las 1 529 biopsias de próstata realizadas durante el período de estudio, hubo 680 (44,0 por ciento) casos con diagnóstico de cáncer de próstata. De estos, 458 pacientes habían recibido tratamiento de supresión androgénica y se disponía de sus registros completos para el análisis. La edad media de los pacientes fue de 72 años. Durante el período de estudio, se les practicó castración quirúrgica a 265 pacientes (58,0 por ciento) y castración farmacológica a 193 (42,0 por ciento). La proporción de orquiectomías fue mayor antes de marzo del 2005 que después de esa fecha (P < 0,001). Los estrógenos fueron el método de castración farmacológica más común antes de la creación del subsidio del NHF (62,0 por ciento); a partir de ese momento se eligieron con mayor frecuencia los análogos de la hormona liberadora de la hormona luteinizante (38,0 por ciento) y los antiandrógenos (36,5 por ciento). CONCLUSIONES: La castración quirúrgica era más común que la castración farmacológica antes de marzo del 2005. Después de que el NHF empezó a subsidiar el costo de los medicamentos para el tratamiento hormonal, la opción escogida con más frecuencia fue la castración farmacológica. El mayor acceso a los medicamentos usados en la hormonoterapia ha cambiado los patrones de tratamiento del cáncer de próstata en Jamaica.
