Exploration of the treatment challenges in men with intellectual difficulties and testicular cancer as seen in Down syndrome: single centre experience.

Down syndrome is the most common chromosomal disorder in humans as well as the most common cause of inherited intellectual disability. A spectrum of physical and functional disability is associated with the syndrome as well as a predisposition to developing particular malignancies, including testicular cancers. These tumours ordinarily have a high cure rate even in widely disseminated disease. However, individuals with Down syndrome may have learning difficulties, behavioural problems, and multiple systemic complications that have the potential to make standard treatment more risky and necessitates individualized approach in order to avoid unacceptable harm. There is also suggestion that tumours may have a different natural history. Further, people with learning disabilities have often experienced poorer healthcare than the general population. In order to address these inequalities, legislation, professional bodies, and charities provide guidance; however, ultimately, consideration of the person in the context of their own psychosocial issues, comorbidities, and possible treatment strategies is vital in delivering optimal care. We aim to present a review of our own experience of delivering individualized care to this group of patients in order to close the existing health inequality gap.

Multi-disciplinary management for patients with oligometastases to the brain: results of a 5 year cohort study.

BACKGROUND: The incidence of oligometastases to the brain in good performance status patients is increasing due to improvements in systemic therapy and MRI screening, but specific management pathways are often lacking. METHODS: We established a multi-disciplinary brain metastases clinic with specific referral guidelines and standard follow-up for good prognosis patients with the view that improving the process of care may improve outcomes. We evaluated patient demographic and outcome data for patients first seen between February 2007 and November 2011. RESULTS: The clinic was feasible to run and referrals were appropriate. 87% of patients referred received a localised therapy during their treatment course. 114 patients were seen and patient numbers increased during the 5 years that the clinic has been running as relationships between clinicians were developed. Median follow-up for those still alive was 23.1 months (6.1-79.1 months). Primary treatments were: surgery alone 52%, surgery plus whole brain radiotherapy (WBRT) 9%, radiosurgery 14%, WBRT alone 23%, supportive care 2%. 43% received subsequent treatment for brain metastases. 25%, 11% and 15% respectively developed local neurological progression only, new brain metastases only or both. Median overall survival following brain metastases diagnosis was 16.0 months (range 1-79.1 months). Breast (32%) and NSCLC (26%) were the most common primary tumours with median survivals of 26 and 16.9 months respectively (HR 0.6, p=0.07). Overall one year survival was 55% and two year survival 31.5%. 85 patients died of whom 37 (44%) had a neurological death. CONCLUSION: Careful patient selection and multi-disciplinary management identifies a subset of patients with oligometastatic brain disease who benefit from aggressive local treatment. A dedicated joint neurosurgical/ neuro-oncology clinic for such patients is feasible and effective. It also offers the opportunity to better define management strategies and further research in this field. Consideration should be given to defining specific management pathways for these patients within general oncology practice.

Medium-term outcomes of active surveillance for localised prostate cancer.

BACKGROUND: Active surveillance (AS) aims to allow men with favourable-risk, localised prostate cancer to avoid unnecessary treatment. OBJECTIVE: To describe the clinical outcomes of a prospective study of AS. DESIGN, SETTING, AND PARTICIPANTS: A single-centre, prospective cohort study. Eligibility criteria included histologically proven prostate adenocarcinoma, age 50-80 yr, stage T1/T2, prostate-specific antigen level (PSA) <15 ng/ml, Gleason score (GS) ≤ 3+3 (GS ≤ 3+4 if aged >65 yr), and percent positive biopsy cores (PPC) ≤ 50%. INTERVENTION: Patients were assessed by serum PSA level, and digital rectal examination at 3-mo intervals in year 1, 4-mo intervals in year 2, and at 6-mo intervals thereafter. Transrectal ultrasound-guided prostate biopsy was performed after 18-24 mo and every 2 yr thereafter. Treatment was recommended for PSA velocity (PSAV) >1 ng/ml per year or adverse histology, defined as GS ≥ 4+3 or PPC >50%. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcomes described, using Kaplan-Meier methods, were rate of adverse histology on repeat biopsy, freedom from treatment, biochemical control after deferred treatment, and overall survival. Analyses using Cox regression were performed to determine predictors of deferred treatment and adverse histology. RESULTS AND LIMITATIONS: The study enrolled 471 eligible patients from 2002 to 2011. Median age was 66 yr and median initial PSA value was 6.4 ng/ml. Eighty-eight percent of patients had T1 disease and 93% had GS ≤ 3+3. At median follow-up of 5.7 yr, the 5-yr rate of adverse histology and treatment-free probability was 22% (95% confidence interval [CI], 16-29%) and 70% (95% CI, 65-75%), respectively. There were two deaths from prostate cancer. Predictors of time to adverse histology were GS 7, PSAV >1 ng/ml per year, low ratio of free PSA to total PSA, and PPC >25%. Longer follow-up is needed to confirm the safety of this strategy. CONCLUSIONS: This study demonstrates satisfactory medium-term outcomes for AS in selected men with localised prostate cancer.

Minimizing toxicity in early-stage testicular cancer treatment.

Testicular cancer is the paradigm of a curable malignancy, with 10-year survival rates exceeding 95%. Cisplatin-based regimes offer a survival gain of several decades of life; however, measures of outcomes in testicular cancer are evolving. Survivorship issues are becoming increasingly important in this young adult population. Long-term risks of second malignancy and cardiovascular disease secondary to chemotherapy and radiotherapy have been extensively documented, leading to an increased uptake of surveillance. However, the optimal surveillance schedule is not universally agreed upon. Research into modalities to detect relapse and frequency is ongoing. Reducing the treatment burden with fewer cycles of chemotherapy (one cycle of bleomycin, cisplatin and etoposide instead of two for stage I high-risk nonseminomatous tumors) or less toxic alternatives (carboplatin instead of radiotherapy for stage I seminomas) is currently being explored. This article details the toxicities associated with the diagnosis and treatments of early-stage testicular cancer and current strategies used to minimize toxicity while retaining the excellent cure rates.
