Six-Month Survivorship Prediction in Spinal Metastatic Patients by Oncologists Shows Reliable Prognostication.

STUDY DESIGN: A retrospective analysis of oncologist-provided prognoses vs actual survival outcomes of patients referred with Metastatic spinal cord compression (MSCC) to a supra-regional multidisciplinary team (MDT). OBJECTIVES: Prognostic scoring systems, such as the revised Tokuhashi, are commonly used to help guide the treatment of MSCC. However, scoring systems do not accommodate for the improved outcomes of contemporary cancer therapy. Oncologist-provided prognoses play an important role in real world rapid decision making. There is a paucity of evidence assessing the accuracy of the oncologist-provided prognosis. We conducted a retrospective study to evaluate this. METHODS: Data was captured between January 2015 and December 2018. Patients were split into 2 groups: Group 1 (prognosis estimated <6 months) and Group 2 (prognosis estimated >6 months). Median overall survival (mOS) and hazard ratio for death (HR) was assessed. Receiver operating characteristic (ROC) analysis was performed to assess the accuracy of the oncologist's prognosis. RESULTS: 829 patients were included. mOS in Group 1 was 5.8 months (95% CI 4.2-7.4 m), and in Group 2 mOS was not reached. Log rank test gave a Chi2 of 131 (P < .001). Cox regression analysis revealed a HR of .30 (P < .001). Area under the ROC curve was 78%. CONCLUSIONS: Oncologist-provided prognosis is accurate in this cohort of unselected, consecutive MSCC patients. It reduced reliance on scoring systems that can become outdated. Given the rapid progress in cancer treatment, the oncologist's prognostic prediction is integral in efficient and effective MSCC management to help rapidly determine surgical candidacy.

A new prognostic model for predicting 30-day mortality in acute oncology patients.

INTRODUCTION: Acute oncology services (AOS) provide rapid review and expedited pathways for referral to specialist care for cancer patients. Blood tests may support AOS in providing estimates of prognosis. We aimed to develop and validate a prognostic model of 30-day mortality based on routine blood markers to inform an AOS decision to actively treat or palliate patients. METHODS AND MATERIALS: Using clinical data from 752 AOS referrals, multivariable logistic regression analysis was conducted to develop a 30-day mortality prognostic model. Internal validation and then internal-external cross-validation were used to examine overfitting and generalizability of the model's predictive performance. RESULTS: Urea, alkaline phosphatase, albumin and neutrophils were the strongest predictors of outcome. The model separated patients into distinct prognostic groups from the cross-validation (C Statistic: 0.70; 95% CI: 0.64-0.76). Admission year was included as a predictor in the model to improve the model calibration. CONCLUSION: The developed prediction model was able to classify patients into distinct prognostic risk groups, which is clinically useful for delivering an evidence-based AOS. Collation of data from other AOS centers would allow for the development of a more generalizable prognostic model.

Long-term multicentre experience of adjuvant radiotherapy for pN3 squamous cell carcinoma of the penis.

OBJECTIVE: To present the long-term adjuvant radiotherapy outcomes of patients with pN3 squamous cell carcinoma of the penis (SCCp) treated at two UK centres. PATIENTS AND METHODS: We conducted a retrospective audit of all pN3 SCCp patients, deemed suitable for adjuvant therapy by a specialist multidisciplinary team at St George's and Leeds Hospitals, who received adjuvant radiotherapy. Primary outcomes were recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Secondary outcomes were time to adjuvant treatment, frequency of in-field recurrence, site and side of recurrence, and dose and schedule of radiotherapy. RESULTS: A total of 146 patients were included: 121 completed radiotherapy, 4 did not complete radiotherapy and 21 did not start it. The median (interquartile range [IQR]) age was 59 (54-70)years. The 5-year RFS was 51%, CSS was 51% and OS was 44%. Adjuvant radiotherapy was started at a median (IQR) of 75 (48-106) days. A dose of 45 Gy in 20 fractions was most commonly used. Of the 125 patients who started adjuvant treatment, 55 relapsed. Of these relapses, 30 occurred in an inguinal or pelvic nodal station and 26 of the 30 were in a radiation field. Relapses in 18 of the 55 cases were in visceral sites only and seven were in both nodal (non-irradiated sites) and visceral sites. Doses of <50 Gy were used more commonly before 2013 and higher doses (>50 Gy) were more commonly used after 2013. CONCLUSIONS: Application of a standard radiotherapy protocol within a centralized supra-network setting has achieved survival outcomes that would appear better than those previously documented for either radiotherapy or chemotherapy in a cohort with solely pN3 disease. The addition of adjuvant chemotherapy may improve these outcomes further. These data suggest that adjuvant radiotherapy has a role to play in the management of men with pN3 SCCp.

Nocardia farcinica masquerading as intracerebral metastases in advanced metastatic prostatic cancer.

A 67-year-old man with metastatic prostate cancer and underlying asymptomatic pancytopenia presented with a 1-week history of general malaise, left leg weakness and facial numbness. Initial brain imaging demonstrated two rim-enhancing lesions felt to represent intracerebral metastasis. Following neurosurgical referral, a multidisciplinary meeting decision was made for best supportive care and dexamethasone was given. He developed multiple cutaneous lesions, which on incision and drainage revealed Nocardia farcinica Repeat brain imaging showed enlargement of the existing cavitating lesions and appearance of new lesions, now typical of cerebral abscesses. A diagnosis of disseminated nocardiosis with cutaneous and intracerebral infection was reached. He started taking empirical treatment with intravenous meropenem, co-trimoxazole and subsequent addition of amikacin, with little improvement. On further review of sensitivities, moxifloxacin was added. Following over 1 month of antimicrobial treatment, his neurological symptoms, cutaneous lesions and repeat MRI of the brain had improved.

Red cell differential width (RDW) as a predictor of survival outcomes with palliative and adjuvant chemotherapy for metastatic penile cancer.

PURPOSE: Red cell distribution width (RDW) measures red cells' size variability. Metastatic penile cancer displays poor chemotherapy response. As no validated prognostic predictor exists, we investigated whether RDW correlates independently with survival outcomes in metastatic penile cancer treated by chemotherapy. METHODS: Electronic chemotherapy files of patients with metastatic penile cancer (M1 or N3) from a large academic supra-regional centre were retrospectively analysed between 2005 and 2018. Patients were stratified into RDW > 13.9% and < 13.9%, as per published data on RDW in renal cell carcinoma. Survival time was calculated from the date of chemotherapy initiation until the date of death. RESULTS: 58 patients were analysed. The RDW-high group (n = 31) had a poorer survival than the RDW-low group (n = 27). Median overall survival (mOS) in all patients was 19.0 months (95% CI 13.1-24.9). mOS for RDW-high was 15.0 months (95% CI 10.1-19.9) and 37.0 months (95% CI 32.3-43.1) for RDW-low. Kaplan-Meier curves showed a clear disparity in survival (log rank p = 0.025). Cox proportional hazard ratio for death, corrected for T-stage, grade, age and deprivation score was 0.43 (p = 0.04). Sub-analysis of the M1 patients showed mOS in RDW-high of 17 m (95% CI 11.6-22.4) vs. NR; HR for death of 0.42. N3 patients' mOS in RDW-high cohort was 30 months (95% CI 4.5-55.9) vs. 13 months (95% CI 1.8-24.2) in RDW-low; HR for death was 0.30. CONCLUSION: RDW correlates independently with survival outcomes in metastatic penile cancer and may act as a potential predictor of survival outcomes for patients with metastatic penile cancer receiving chemotherapy.

Do Learning Disabilities Affect Testicular Cancer Survival: A National Cohort Study Between 2001 and 2015.

BACKGROUND: Some 1.5 million people in the UK have a learning disability (LD). This vulnerable group derives less benefit from population-based education programs. They are prone to underenrolment in screening programs and may lack the ability to perform self-examination. OBJECTIVE: To identify patients with LD in England and assess their testicular cancer (TC) survival in comparison to the general population. DESIGN, SETTING, AND PARTICIPANTS: Patient records were identified from the Hospital Episode Statistics database. All patients resident in England with a diagnosis of mental debility, "developmental disorder of scholastic skills", or attending under the specialty of LD between April 1, 2001 and June 30, 2015 were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We measured survival outcomes according to the Kaplan-Meier method and used log-rank tests to assess survival difference between demographic groups. RESULTS AND LIMITATIONS: Of 158138 male patients with LD, 331 had TC and 32 died of cancer. LD patients had a poorer prognosis, with 10-yr TC-specific survival of 88.4% (95% confidence interval [CI] 84.5-92.4%) in the LD group versus 96.8% (95% CI 96.6-97.1%) in the non-LD group. LD patients also had lower all-cause survival rates. The 10-yr survival rate was 77.6% (95% CI 72.2-83.3%) for LD patients versus 89.9% (95% CI 89.4-90.3%) for non-LD patients, while the corresponding 5-yr rates were 84% (95% CI 79.9-88.4%) versus 92.2% (95% CI 91.8-92.5%). CONCLUSIONS: Education regarding self-examination for TC must be provided in a format suitable for those with LD. Carers for male patients with LD should be informed about testicular examination and sinister signs. PATIENT SUMMARY: Testicular cancer patients who also have a learning disability (LD) have a one in nine chance of dying, compared to a one in 36 chance for testicular cancer patients without LD. This is because patients with LD are less likely to detect the disease at an earlier stage.

Chronic tyrosine kinase inhibitor (TKI) use in metastatic renal cell carcinoma (mRCC): can this lead to the adverse effect of hypogonadism?

Background: Patients with metastatic renal cell carcinoma (mRCC) are commonly treated with tyrosine kinase inhibitors (TKIs). An adverse effect frequently suffered by patients is lethargy, which often leads to dose reduction or drug cessation. We aimed to assess whether hypogonadism is related to treatment with TKIs. Methods: We prospectively assessed gonadal function in 41 consecutive males with mRCC treated with TKIs. Demographic, clinical, and biochemical variables were collected, and statistical analyses performed to assess correlation and survival. Data Capture for each patient was perfomred at the time of entry in the study. Results: There was a 77% incidence of hypogonadism in this cohort. Assessment of testosterone level and time on TKI treatment revealed a correlation with linear regression R2 of 0.24 and regression coefficient of -0.003 (p = 0.019). Odds ratio for hypogonadism at >30 months on TKIs was 12.1 (p = 0.011). Odds ratios above and below this value showed a confirmatory trend, suggesting that this may be a chronic adverse effect. Conclusions: Our findings provide an important and robust hypothesis for a prospective clinical trial to be performed. Expert Opinion: Given the present data, patients who have symptoms suggestive of hypogonadism must have an assessment of gonadal function and be treated.

Non-secretion of AFP and neutrophil lymphocyte ratio as predictors for survival in hepatocellular carcinoma patients treated with sorafenib: a large UK cohort.

BACKGROUND: Sorafenib is the current standard of care for patients with advanced or metastatic hepatocellular carcinoma. Currently no universally agreed model exists correlating the Neutrophil Lymphocyte ratio (NLR) and non-secretion of AFP with the survival of HCC patients treated with sorafenib. PATIENTS AND METHODS: We retrospectively analysed patient records with a confirmed diagnosis of HCC treated with sorafenib between April 2009 and March 2014. Survival analysis was performed using the Kaplan-Meier method and Cox regression. RESULTS: Patients separated into groups based on NLR (≤3 or >3), or AFP secretion profile (<7 ng/ml or ≥7 ng/ml) derived diverging Kaplan-Meier curves for overall survival (OS). The median OS in those with NLR ≤3.0 was 9.0 months (95% CI: 7.7-11.1 months) and in those with NLR >3.0 it was 6.0 months (95% CI: 4.9-8.2 months) [HR 1.32 (95% CI: 0.96-1.80)]. The median overall survival post sorafenib was higher in the "non-secretor" AFP group. OS for AFP <7 ng/ml was 10.0 months (95% CI: 7.7-19.3 months) compared to AFP ≥7ng/ml: 6.6 months (95% CI: 5.3-8.4 months) [HR 1.64 (95% CI: 1.15-2.33)]. CONCLUSION: NLR and AFP non - secretion at diagnosis are potential significant prognosticators for overall survival from initiation of sorafenib.

Centralisation of radical cystectomies for bladder cancer in England, a decade on from the 'Improving Outcomes Guidance': the case for super centralisation.

OBJECTIVE: To analyse the impact of centralisation of radical cystectomy (RC) provision for bladder cancer in England, on postoperative mortality, length of stay (LoS), complications and re-intervention rates, from implementation of centralisation from 2003 until 2014. In 2002, UK policymakers introduced the 'Improving Outcomes Guidance' (IOG) for urological cancers after a global cancer surgery commission identified substantial shortcomings in provision of care of RCs. One key recommendation was centralisation of RCs to high-output centres. No study has yet robustly analysed the changes since the introduction of the IOG, to assess a national healthcare system that has mature data on such institutional transformation. PATIENTS AND METHODS: RCs performed for bladder cancer in England between 2003/2004 and 2013/2014 were analysed from Hospital Episode Statistics (HES) data. Outcomes including 30-day, 90-day, and 1-year all-cause postoperative mortality; median LoS; complication and re-intervention rates, were calculated. Multivariable statistical analysis was undertaken to describe the relationship between each surgeon and the providers' annual case volume and mortality. RESULTS: In all, 15 292 RCs were identified. The percentage of RCs performed in discordance with the IOG guidelines reduced from 65% to 12.4%, corresponding with an improvement in 30-day mortality from 2.7% to 1.5% (P = 0.024). Procedures adhering to the IOG guidelines had better 30-day mortality (2.1% vs 2.9%; P = 0.003) than those that did not, and better 1-year mortality (21.5% vs 25.6%; P < 0.001), LoS (14 vs 16 days; P < 0.001), and re- intervention rates (30.0% vs 33.6%; P < 0.001). Each single extra surgery per centre reduced the odds of death at 30 days by 1.5% (odds ratio [OR] 0.985, 95% confidence interval [CI] 0.977-0.992) and 1% at 1 year (OR 0.990, 95% CI 0.988-0.993), and significantly reduced rates of re-intervention. CONCLUSION: Centralisation has been implemented across England since the publication of the IOG guidelines in 2002. The improved outcomes shown, including that a single extra procedure per year per centre can significantly reduce mortality and re-intervention, may serve to offer healthcare planners an evidence base to propose new guidance for further optimisation of surgical provision, and hope for other healthcare systems that such widespread institutional change is achievable and positive.

A Study of Angiogenesis Markers in Patients with Renal Cell Carcinoma Undergoing Therapy with Sunitinib.

BACKGROUND: Sunitinib is a tyrosine kinase inhibitor (TKI) targeting tumour angiogenesis in patients with advanced renal cell carcinoma (RCC). Currently no universally agreed model exists correlating the expression of angiogenesis markers with the success of treatment. PATIENTS AND METHODS: We retrospectively analysed archival tissue for 59 RCC patients treated with sunitinib. The expression of angiogenesis markers VEGF-A, VEGFR, PDGFßß, PDGFR, CCND1 and CA9 was assessed by immunohistochemistry (IHC) and correlated with overall survival (OS) and progression-free survival (PFS). RESULTS: The median OS and median PFS of the whole group of patients was 24.6 months (17.3-34.2) and 19.5 months (11-27) respectively. VEGFA was positive in 29% of tumors, whereas VEGFR was expressed in only 12% of tumours. PDGFßß and its receptor were detected in a minority of cases. CCND1 and CA9 were positive in 44% and 60% of cases. CONCLUSION: The OS and PFS achieved by our patients reflected previous observations seen with sunitinib, but no correlation was found between expression of angiogenesis markers and clinical outcome.

Clinical Relevance of the First Domomedicine Platform Securing Multidrug Chronotherapy Delivery in Metastatic Cancer Patients at Home: The inCASA European Project.

BACKGROUND: Telehealth solutions can improve the safety of ambulatory chemotherapy, contributing to the maintenance of patients at their home, hence improving their well-being, all the while reducing health care costs. There is, however, need for a practicable multilevel monitoring solution, encompassing relevant outputs involved in the pathophysiology of chemotherapy-induced toxicity. Domomedicine embraces the delivery of complex care and medical procedures at the patient's home based on modern technologies, and thus it offers an integrated approach for increasing the safety of cancer patients on chemotherapy. OBJECTIVE: The objective was to evaluate patient compliance and clinical relevance of a novel integrated multiparametric telemonitoring domomedicine platform in cancer patients receiving multidrug chemotherapy at home. METHODS: Self-measured body weight, self-rated symptoms using the 19-item MD Anderson Symptom Inventory (MDASI), and circadian rest-activity rhythm recording with a wrist accelerometer (actigraph) were transmitted daily by patients to a server via the Internet, using a dedicated platform installed at home. Daily body weight changes, individual MDASI scores, and relative percentage of activity in-bed versus out-of-bed (I

Can D-Dimer Measurement Reduce the Frequency of Radiological Assessment in Patients Receiving Palliative Imatinib for Gastrointestinal Stromal Tumor (GIST)?

Imatinib therapy has improved outcomes in advanced GISTs. Current guidelines suggest monitoring with CT scanning every 12 weeks. There are no validated biomarkers to assist disease evaluation. We identified 50 patients treated with imatinib for GIST in a single tertiary center. We assessed the prognostic value of D-dimers by Cox regression, and the utility as a biomarker for radiological progression (rPD) using receiver-operator curve (ROC) analysis. In asymptomatic patients with D-dimer levels <1,000 and falling levels, the negative predictive value for rPD was 92%. D-dimers may reduce the burden of CT scanning in a proportion of patients in this setting.

Shifting paradigms in the estimation of survival for castration-resistant prostate cancer: A tertiary academic center experience.

OBJECTIVES: Castration-resistant prostate cancer (CRPC) has retained a guarded prognosis, with historical survival estimates of 18 to 24 months. However, the landscape of available therapy has changed, and the emphasis has altered from supportive to active treatment. Few large series from real-world populations exist in the contemporary era with fully mature survival data to confirm the indication based on clinical trials that patients with CRPC are surviving far longer than the historical estimates. We aim to review a large patient cohort with CRPC and provide mature survival data. METHODS AND MATERIALS: Using the electronic histopathology database at Queen Elizabeth Hospital, Birmingham, UK, all prostate-specific antigentest results between April 2006 and September 2007 were extracted, and patients satisfying the American Society for Radiation Oncology (ASTRO) definition of hormone failure were identified. Electronic records were reviewed and variables were collected, including survival, treatment, biochemistry, histopathology, and demographics. Probability of survival, and of developing metastasis or CRPC, was determined using the Kaplan-Meier method. Patients were stratified into 3 groups, namely, D0--no metastasis at diagnosis but later appearance, D1--no metastasis at diagnosis or at last follow-up, and D2--metastasis at diagnosis. RESULTS: From 8,062 patient-prostate-specific antigen episodes, we identified 447 patients meeting the criteria. A notes review revealed 147 patients with CRPC. Median overall survival (OS) from diagnosis was 84.7 months (95% CI: 73-89), and 129 deaths had occurred (88%). Median OS from diagnosis for D0, D1, and D2 patients was 100.4, 180.1, and 58.9 months, respectively (P< 0.0001), and median OS from CRPC was 40 months (95% CI: 31-58), 82.9 (95% CI: 72-94; P = 0.0125), and 38.7 months (95% CI: 33-46), respectively. One-quarter of patients survived 6 years after development of CRPC. Metastasis is the key prognostic event. CONCLUSIONS: Some current international guidelines quote ≤19 months as a survival figure for patients with metastatic CRPC. In our study, median survival is more than double this. We have shown survival more than previously reported figures and believe that these data benefit clinicians and patients in understanding prognosis and treatment choices. Importantly, our patients were diagnosed before the current wave of novel therapeutics for CRPC, so survival for men diagnosed today may be more than our findings.

Predictive factors for response to abiraterone in metastatic castration refractory prostate cancer.

BACKGROUND: Management of metastatic castration refractory prostate cancer (CRPC) is rapidly evolving. Rationalisation of treatment requires identification of those patients more likely to benefit from a particular therapy. We reviewed the outcome of patients treated with abiraterone at our Institution to describe factors predictive for response. PATIENTS AND METHODS: Patients with CRCP treated with abiraterone were identified. Baseline variables and potential prognostic factors were extracted from electronic records. Outcome measures included overall survival (OS), prostate-specific antigen (PSA) response and time to PSA progression (TTPP). The Kaplan-Meier method and Cox proportional hazards model were used to analyze survival data. RESULTS: A total of 61 patients met the inclusion criteria. In multivariate analysis, three independent predictors of OS were identified: Duration of response to androgen deprivation therapy (ADT) (hazard ratio(HR)=0.95, p=0.006), performance status (HR=7.4, p=0.013), and baseline haemoglobin (HR=0.47, p≤0.001). CONCLUSION: This study has identified three factors predictive for response to abiraterone in CRPC. Duration of response to ADT has not been previously shown to be a predictive factor for patients with CRCP. We suggest that a prospective validation is required.

Temsirolimus for patients with metastatic renal cell carcinoma: outcomes in patients receiving temsirolimus within a compassionate use program in a tertiary referral center.

AIM: Temsirolimus has shown efficacy as first-line treatment of patients with metastatic renal cell carcinoma and poor prognostic features. The efficacy of temsirolimus in other clinical settings, such as second-line therapy, is unclear. The aim of this study was to investigate the outcomes of an unselected group of patients with renal cancer treated with temsirolimus in a compassionate use program. PATIENTS AND METHODS: This retrospective analysis included all patients receiving temsirolimus at a tertiary referral center between November 2007 and October 2008. Information was obtained through review of patient notes, electronic records, and pharmacy records. Baseline characteristics, prognostic features, and previous treatments were recorded for all patients. Outcome measures were response rate, progression-free survival (PFS), overall survival (OS), and toxicities. RESULTS: Thirty-eight patients were included in the analysis, with median age of 62 years, among whom 37% were untreated and 63% had received one or more previous treatments. Thirty-four percent of the patients had three or more poor prognostic factors. Four patients (11%) achieved a partial response (PR); in all four of these patients, the PR was confirmed by two subsequent computed tomography (CT) scans, and in one patient, the PR lasted for more than 18 months. A total of 34% achieved stable disease, and 50% had disease progression. Median OS was 7.6 months (95% confidence interval [CI] 4.8-10.5), and median PFS was 3.2 months (95% CI 1.0-5.5). Patients with two or fewer poor prognostic factors had a survival of 10.12 months compared with 5.03 months of those with three or more. Median survival was 14.9 months for untreated patients and 6.4 months for previously treated patients. CONCLUSION: Our results indicate some efficacy of temsirolimus in untreated patients with renal tumors and poor-intermediate prognosis, although the limitations of small sample size and retrospective nature must be taken into account. The role of temsirolimus in previously treated patients remains controversial given the recently published results of the INTORSECT trial and the discrepancies between the few published series.

Biliary stenting in advanced malignancy: an analysis of predictive factors for survival.

PURPOSE: Stenting of the biliary tree is a common palliative procedure to relieve obstructive jaundice in advanced malignancy. Although effective in relief of biliary obstruction and palliation of symptoms, little information is available on predictive factors for survival post-procedure. This retrospective study sought to assess factors influencing post-procedure survival in cancer patients after biliary stenting. METHODS: Case notes of all patients from a regional academic cancer center, who underwent biliary stenting for obstructive jaundice related to malignancy during 2008 and 2009 were reviewed. We collected epidemiological, biochemical, treatment and survival data on all patients. We used Kaplan-Meyer analysis to assess survival from day of first biliary stenting (adjusted for cancer types), and the Cox proportional hazards model for univariate and multivariate analysis. RESULTS: One hundred and ninety-four patients were included in the final analysis. Most cases were related to pancreatic cancer or cholangiocarcinoma (89 and 46 cases respectively). Median survival for all patients was 143 days. In multivariate analysis serum albumin ≥34 g/L at the time of procedure (hazard ratio 0.573; 95% confidence interval 0.424-0.773, P<0.001) and chemotherapy post-stent (hazard ratio 0.636; 95% confidence interval 0.455-0.889, P=0.008) were two independent prognostic factors predicting a better survival post-stenting. The 30 day mortality post-procedure in the 194 patients was 12%. CONCLUSION: This study suggests that stenting of the biliary tree in cases of malignant obstruction allows durable palliation of symptoms even in cases where further active chemotherapy treatment is not possible. However, the better outcome observed in patients with albumin ≥34 g/L and those receiving chemotherapy post-stent requires further validation.
