RESUMO

PURPOSE: The National Cancer Institute has highlighted the need for psychosocial research to focus on Black cancer patients. This applies to Black men with prostate cancer, as there is little systematic research concerning psychological distress in these men. This study was designed to validate the Memorial Anxiety Scale for Prostate Cancer (MAX-PC) in Black men with prostate cancer to help facilitate research within this group. METHODS: At three institutions, Black men with prostate cancer (n = 101) completed the MAX-PC, the Hospital Anxiety and Depression Scale (HADS), the Functional Assessment of Cancer Therapy (FACT) Quality of Life Questionnaire, and the Distress Thermometer. RESULTS: The average age of the 101 men was 66 (SD = 10) and 58 % had early-stage disease. The MAX-PC and its subscales (Prostate Cancer Anxiety, PSA Anxiety, and Fear of Recurrence) produced strong coefficient alphas (0.89, 0.88, 0.71, and 0.77, respectively). Factor analysis supported the three-factor structure of the scale established in earlier findings. The MAX-PC also demonstrated strong validity. MAX-PC total scores correlated highly with the Anxiety subscale of the HADS (r = 0.59, p < 0.01) and the FACT Emotional Well-Being subscale (r = -0.55, p < 0.01). Demonstrating discriminant validity, the correlation with the HADS Depression subscale (r = 0.40, p < 0.01) and the CES-D (r = 0.42, p < 0.01) was lower compared to that with the HADS Anxiety subscale. CONCLUSIONS: The MAX-PC is valid and reliable in Black men with prostate cancer. We hope the validation of this scale in Black men will help facilitate psychosocial research in this group that is disproportionately adversely affected by this cancer.

RESUMO

PURPOSE: We evaluated the outcome and etiologies of small renal masses (less than 1 cm in size) discovered incidentally on 2 consecutive CTs that investigated nonurologic abdominal complaints. MATERIALS AND METHODS: A retrospective search for incidentally discovered small renal masses, less then 1 cm in size, was carried out in the files of 6 major US medical centers. 4822 such lesions had been reported over a 12 year period. A search of these patients' records revealed 1082 subsequent new CTs for non urologic complaints, allowing the assessment of the fate of the masses. Lesions enlarging, of ambivalent contour or enhancement were examined by a third multiphasic MDCT. The findings were interpreted by 2 blinded radiologists. RESULTS: Six hundred and four masses could no longer be identified, 231 were significantly smaller, 113 unchanged in size and 134 larger. Of the disappearing lesions 448 were located in the medulla, 94 both in medulla and cortex and 62 in cortex. Multiphasic MDCTs obtained in 308 masses enlarging, unchanged in size or of ambivalent appearance, revealed 7 neoplasms, 45 inflammatory lesions, 8 abscesses and 62 renal medullary necrosis. Concurrent antibiotic therapy of GI conditions may have caused some of the 496 lesions to disappear. CONCLUSION: It is questionable whether the small number of malignant neoplasms (0.4%), inflammatory lesions (5%) and renal medullary necrosis (6%) justify routine follow-up CTs and exposure to radiation. The delay in intervention in neoplastic lesions probably didn't influence tumor-free survival potential and clinical symptoms would soon have revealed inflammatory conditions. With exception of ambivalent lesions, clinical surveillance appears adequate.

RESUMO

PURPOSE: We sought to identify racial differences among histological subtypes of renal cell carcinoma (RCC) between black and non-black patients in an equal-access health care system. MATERIALS AND METHODS: We established a multi-institutional, prospective database of patients undergoing partial or radical nephrectomy between January 1, 2000 and Sept 31, 2009. For the purposes of this study, data captured included age at diagnosis, race, tumor size, presence of lymphovascular invasion, presence of capsular invasion, margin status, and tumor histology. RESULTS: 204 kidney tumors were identified (Table-1). Of these, 117 (57.4%) were in black patients and 87 (42.6%) were in non-black patients. Age at surgery ranged from 37 to 87 with a median of 62. Tumor size ranged from 1.0 to 22.0 cm with a median of 5.0 cm. Overall, tumors were composed of clear cell RCC in 97 cases (47.5%), papillary RCC in 65 cases (31.9%), chromophobe RCC in 13 cases (6.4%), collecting duct/medullary RCC in 2 cases (1.0%), RCC with multiple histological subtypes in 8 cases (3.9%), malignant tumors of other origin in 6 cases (2.9%), and benign histology in 13 cases (6.4%). Among black patients, papillary RCC was seen in 56 cases (47.9%), compared to 9 cases (10.3%) among non-black patients (p < 0.001) (Table-2). Clear cell RCC was present in 38 (32.5%) of black patients and in 59 (67.8%) of non-blacks (p < 0.001). CONCLUSIONS: In our study, papillary RCC had a much higher occurrence among black patients compared to non-black patients. This is the first study to document such a great racial disparity among RCC subtypes.

RESUMO

PURPOSE: When faced with biochemical recurrence after definitive radiotherapy for prostate cancer, clinicians must determine whether the recurrence is local or systemic. Post radiotherapy prostate biopsies to detect persistent local disease are difficult to interpret histopathologically and are subject to sampling error. Our study examines outcomes for patients with a negative prostate biopsy performed for rising prostate-specific antigen (PSA) levels after prostate radiation. MATERIALS AND METHODS: We performed a retrospective review of 238 prostate cancer patients with a negative biopsy following definitive radiotherapy. Seventy-five of these patients had biochemical recurrence at the time of biopsy. A negative biopsy was defined as the absence of prostate cancer without radiation-treatment effect in the specimen. RESULTS: Patients underwent biopsy at a mean of 41 months after the completion of radiation. They had a mean PSA of 6. Patients were followed for an average of 63 months. Thirty-two patients (43%) developed metastasis, and 11 (15%) died of prostate cancer despite a negative post-radiation biopsy. Five of nine patients (56%) with sequential biopsies had a positive second biopsy. CONCLUSIONS: Patients with PSA recurrence and a negative post-radiation biopsy have a high chance of persistent local disease, progression, and death from prostate cancer. Furthermore, an initial negative biopsy does not rule-out local recurrence. Patients with biochemical recurrence after radiotherapy for prostate cancer need to be evaluated earlier for local recurrence.

RESUMO

PURPOSE: The purpose of this study was to develop and test the efficacy of a prostate health curriculum designed to train African American and Afro Caribbean barbers to deliver prostate cancer control messages to their customers. PROCEDURES: The curriculum was drafted from information obtained from needs assessment surveys administered to barbers and customers from various barbershops in Brooklyn, New York. Focus groups were conducted to further inform the curriculum, which was pilot tested in training sessions. FINDINGS: The high incidence of late-stage diagnosis prostate cancer in African Americans has often been attributed to lack of screening. In surveys administered to 92 customers and 19 barbers, only 26% of customers and 42% of barbers reported having some knowledge of the prostate-specific antigen (PSA) screening test. More than 90% of the barbers expressed a willingness to obtain prostate cancer information to specifically share with their customers, and 83% of customers expressed an interest in obtaining prostate cancer information and willingness to receive that information from their barbers. Following the pilot training, barber knowledge of prostate cancer increased significantly (p < .0001). CONCLUSIONS: This pilot study suggests that there is a need for intervention programs that will raise awareness and increase prostate health knowledge and behavior in communities with elevated incidence of prostate cancer. The study further suggests that barbers are willing to use their leadership skills to educate and encourage their customers to engage in informed decision making.
