Sarcopenia as a Predictor of Survival in Patients with Pancreatic Adenocarcinoma After Pancreatectomy.

OBJECTIVE: To determine whether sarcopenia can potentially predict worse survival after resection of pancreatic ductal adenocarcinoma. BACKGROUND: Sarcopenia is correlated with poor outcomes in hepatopancreatobiliary malignancies, but the relationship of both its qualitative and quantitative features with patient survival after pancreatectomy has not been investigated in a western population. PATIENTS AND METHODS: Preoperative cross-sectional computed tomography scans of consecutive patients who underwent pancreatectomy in 2005-2017 were evaluated for skeletal muscle index (SMI), intramuscular adipose tissue content (IMAC), and visceral-to-subcutaneous adipose tissue area ratio (VSR). Sex-specific categorical cut-offs were determined. Findings were correlated with outcome. RESULTS: The study included 111 patients, 47% of whom were female, with a median age of 67 years (range: 35-87 years), and median body mass index of 23 kg/m2 (range: 16-40 kg/m2); 77% had a Whipple procedure and 66% received adjuvant chemotherapy. Low SMI correlated with poor overall survival (OS) (P = 0.007), disease-specific survival (DSS) (P = 0.006), and recurrence-free survival (RFS) (P = 0.01). High IMAC correlated with poor OS (P = 0.04). Patients with high IMAC tended to have a shorter DSS (P = 0.09), with no correlation with RFS (P = 0.6). VSR was not associated with survival. Multivariable analysis yielded an independent association of low SMI with OS (HR = 1.7, 95%CI: 1.1-2.8, P = 0.02), DSS (HR = 1.8, 95%CI: 1.03-3.2, P = 0.04), and RFS (HR = 1.8, 95%CI: 1.1-2.8, P = 0.01), and of high IMAC with OS (HR = 1.9, 95%CI: 1.1-3.1, P = 0.01). CONCLUSION: Both qualitative and quantitative measures of skeletal muscle were independently associated with impaired survival in patients with resectable PDAC. Sarcopenia might serve as an early radiographic surrogate of aggressive tumor behavior, with potential implications for clinical decision-making and future study.

The Dynamic Changing Incidence of Gastric Cancer in Israel: Time for a National Surgical Management Committee?

BACKGROUND: There has been a general reduction over the last 20 years in the incidence within Israel of gastric cancer (GC). This has particularly been noted in the Jewish population with a slight increase in the incidence of cancer of the gastroesophageal junction among Jews of Sephardi origin. Given the diversity of individual ethnic subpopulations, the effects of GC incidence in second-generation immigrant Jews, particularly from high prevalence regions (e.g., the former Soviet Union, Iraq, and Iran), awaits determination. There are currently no national data on GC-specific mortality. The most recent available cross-correlated Israeli National Cancer Registry (INCR) and International Association for Cancer Research (IARC) incidence data for GC of the body and antrum in Israel are presented. Some of the challenges associated with GC monitoring in the changing Israeli population are discussed. We propose the establishment of a national GC management committee designed to collect demographic and oncological data in operable cases with the aim of recording and improving GC-specific outcomes. We believe that there is value in the development of a national surgical planning program, which oversees training and accreditation in a dynamic environment that favors the wider use of neoadjuvant therapies, minimally invasive surgery and routine extended (D2) lymphadenectomy. These changes should be supported by assessable enhanced recovery programs.

Neutrophil-to-Lymphocyte Ratio Predicts Recurrence Pattern in Patients with Resectable Colorectal Liver Metastases.

BACKGROUND: Studies have suggested that neutrophil-to-lymphocyte ratio (NLR) has value as a predictor of long-term outcomes in various cancer types. Its prognostic potential in patients with CRLM has not been thoroughly investigated. This original, retrospective study assessed the relationship between the preoperative NLR, survival outcomes, and recurrence patterns in patients after colorectal liver metastasis resection (CRLM). METHODS: The prospectively maintained database of a tertiary medical center was queried for all patients who underwent CRLM resection between 2005 and 2017. Patients were divided into two groups: NLR <3 (normal) or >3 (high). Recurrence risk was analysed using Fine and Gray correction for competing risk method and cause specific analyses. RESULTS: The cohort included 231 patients of whom 53 (23%) had a high neutrophil-to-lymphocyte ratio. At presentation, 35% had synchronous disease and 48% had a solitary metastasis; median tumor size was 2 cm. Patients with a high NLR had a significantly higher rate of simultaneous colorectal resection (P = 0.01). A high NLR was independently associated with worse OS (P = 0.02), worse DFS (P = 0.03), and higher risk of recurrence (P = 0.048), specifically recurrence with an extrahepatic pattern (P = 0.03). CONCLUSIONS: A high preoperative NLR was independently associated with poorer survival outcomes and extrahepatic recurrence pattern. The NLR appears to have prognostic importance in CRLM and may serve as a surrogate marker of aggressive systemic disease after resection. These findings warrant external validation, preferably in a prospective design.

The trichoscopic features of hair shaft anomalies induced by epidermal growth factor receptor inhibitors: A case series.

BACKGROUND: Although the clinical hair changes that occur under treatment with epidermal growth factor receptor inhibitors (EGFRIs) are documented, their trichoscopic features have not been reported. OBJECTIVE: To evaluate the trichoscopic findings in scalp and facial hair, induced by EGFRI treatment. METHODS: Patients treated with EGFRIs at a tertiary oncodermatology clinic in 2015 through 2017 were evaluated for macroscopic and trichoscopic changes. RESULTS: The cohort included 23 patients (13 women; median age, 68 years) treated with EGFRIs for an average of 13 months (range, 2-40 months). Macroscopically, 18 patients (78%) had dry, lusterless, coarse, kinky, brittle scalp hair, and 17 (74%) had trichomegaly of the eyebrows/eyelashes. Trichoscopic findings were of hair shaft anomalies including pili torti, affecting scalp hair in 20 patients (87%), eyebrows in 6 (26%), and eyelashes in 8 (50%), and asymmetric hyperpigmented fusiform widening of hair scalp in 3 (13%), eyebrows in 10 (43%), and eyelashes in 4 (25%). Dermoscopic findings of the peri- and interfollicular skin were scale, whitish erythematous structureless areas, and branching vessels. LIMITATIONS: Lack of trichoscopic-histologic correlation, lack of baseline examination. CONCLUSION: The trichoscopic correlates of the macroscopic hair changes under EFGRI treatment include pili torti, and asymmetric hyperpigmented fusiform widening, with dermoscopic cutaneous manifestations of scale, whitish erythematous structureless areas, and branching vessels.

Prophylactic Topical Treatment for EGFR Inhibitor-Induced Papulopustular Rash: A Randomized Clinical Trial.

BACKGROUND: The incidence of epidermal growth factor receptor inhibitor (EGFRI)-induced papulopustular rash is 60-85%. OBJECTIVE: To investigate prophylactic topical treatment for EGFRI-induced rash. METHODS: A single-center, randomized, double-blind, placebo-controlled trial. Adult cancer patients initiating treatment with EGFRIs were randomized to receive facial topical treatment with chloramphenicol 3% + prednisolone 0.5% (CHL-PRED) ointment, chloramphenicol 3% (CHL) ointment, or aqua cream (AQUA). The primary end points were the incidence of ≥grade 3 rash using the Common Terminology Criteria for Adverse Events (CTCAE), on days 14 and 30. A subanalysis was conducted for incidence of a protocol-specified significant rash, defined as ≥10 facial papulopustular lesions. RESULTS: The per-protocol analysis on day 14 included 69 patients, who received CHL-PRED (21), CHL (23), or AQUA (25). The incidence of CTCAE ≥grade 3 rash was not statistically significant between arms; however, the incidence of the protocol-specified significant rash was: CHL-PRED 14%, CHL 39%, and AQUA 48% (p = 0.03, CHL-PRED vs. AQUA). At 30 days, the CTCAE ≥grade 3 incidence was similar, but the incidences of protocol-specified significant rash were 6%, 16%, and 43% (p = 0.03, CHL-PRED vs. AQUA). No significant differences were found between CHL and CHL-PRED and between CHL and AQUA. CONCLUSIONS: Prophylactic topical CHL-PRED was efficacious when compared to AQUA, in the treatment of EGFRI-induced facial papulopustular rash.

Young-onset gastric cancer and Epstein-Barr Virus (EBV) - a major player in the pathogenesis?

OBJECTIVE: Gastric cancer (GC) is a leading cause of cancer death, occurs predominantly in older age, with increasing incidence in young patients. The Cancer Genome Atlas indicates four subtypes for GC among which Epstein-Barr virus (EBV) subtype is estimated at 8.7%. We aim to determine the prevalence of EBV subtype in young GC patients (≤45 years) compared with an average-onset cohort (≥55 years) and characterize the clinicopathologic pattern of young-onset GC. METHODS: Gastric cancer samples of patients of both cohorts were screened for EBV by qPCR. Additional staining was done for Human epidermal growth factor receptor 2 (HER2), microsatellite instability (MSI) status and Programmed death-ligand 1 (PD-L1). Demographics and clinical data were retrieved from the medical records. RESULTS: Thirty-nine young-onset and 35 average-onset GC patients were reviewed. There was no apparent difference in tumor location, family history, histology and HER2 status between the cohorts. More young-onset patients were diagnosed with metastatic disease (27% vs 9%, p = 0.0498). EBV was significantly more prevalent in the young-onset cohort (33% vs 11%, p = 0.025). 15/17 EBV positive patients were under the median age of diagnosis for GC in the US (68 years). MSI-H was found only in the average-onset cohort [0% vs 27%, p = 0.001). PD-L1 positivity was higher in the young-onset cohort (31% vs 3%, p = 0.002). CONCLUSION: Our study indicates that EBV subtype is more prevalent in young-onset GC and may play a key role in the pathogenesis. Higher rate of PD-L1 positivity in young-onset GC could change treatment strategies. We are currently evaluating these findings in a prospective trial.

Sidedness Matters: Surrogate Biomarkers Prognosticate Colorectal Cancer upon Anatomic Location.

BACKGROUND: Anatomic location of primary tumors across the colon correlate with survival in the metastatic setting, whereas left-sided tumors may exhibit superior survival compared with right-sided tumors. The Oncotype Recurrence Score (RS) assay is a clinically validated predictor of recurrence risk in patients with stage II colorectal cancer (CRC). Previous studies had indicated that without adjuvant chemotherapy, CDX2-negative stage II CRC tumors are associated with a lower rate of disease-free survival than CDX2-positive stage II CRC tumors. We aimed to evaluate whether these two validated prognostic biomarkers may correlate with primary tumor location, and whether tumor location may reflect differential prognosis in stage II CRC. MATERIALS AND METHODS: We retrospectively analyzed patients with T3 mismatch repair-proficient (MMR-P) stage II CRC for whom RS assay was performed. Pathological report was reviewed for exact primary tumor location and CDX2 immunostaining. RS and CDX2 expression were correlated with primary tumor location. RESULTS: The analysis included 1,147 patients with MMR-P stage II CRC (median age 69 years [range 29-93]). Tumor distribution across the colon was as follows: 46% (n = 551) were right-sided and 54% (n = 596) were left-sided. RS was higher in right-sided tumors (p = .01). The RS results gradually decreased across the colon (cecum, highest score; sigmoid, lowest score; p = .04). Right-sided tumors exhibited more CDX2-negative tumors (p = .07). CONCLUSION: Our study indicates that right-sided colorectal tumors may display worse prognosis compared with left-sided tumors in MMR-P stage II CRC. Primary tumor location may serve as a prognostic factor that should be taken into account for recurrence risk assessment and consideration of adjuvant treatment. IMPLICATIONS FOR PRACTICE: Sidedness matters, even in stage II colorectal cancer (CRC). Using two previously established prognostic tools, the Oncotype DX assay and CDX2 expression, this study found that right-sided tumors may display worse prognosis compared with left-sided tumors in mismatch repair-proficient stage II CRC. Therefore, primary tumor location should be taken into account for recurrence risk assessment and consideration of adjuvant treatment.

Regorafenib for Patients with Metastatic Colorectal Cancer Who Progressed After Standard Therapy: Results of the Large, Single-Arm, Open-Label Phase IIIb CONSIGN Study.

BACKGROUND: In the phase III CORRECT trial, regorafenib significantly improved survival in treatment-refractory metastatic colorectal cancer (mCRC). The CONSIGN study was designed to further characterize regorafenib safety and allow patients access to regorafenib before market authorization. METHODS: This prospective, single-arm study enrolled patients in 25 countries at 186 sites. Patients with treatment-refractory mCRC and an Eastern Cooperative Oncology Group performance status (ECOG PS) ≤1 received regorafenib 160 mg once daily for the first 3 weeks of each 4-week cycle. The primary endpoint was safety. Progression-free survival (PFS) per investigator assessment was the only efficacy evaluation. RESULTS: In total, 2,872 patients were assigned to treatment and 2,864 were treated. Median age was 62 years, ECOG PS 0/1 was 47%/53%, and 74% had received at least three prior regimens for metastatic disease. Median treatment duration was three cycles. Treatment-emergent adverse events (TEAEs) led to dose reduction in 46% of patients. Regorafenib-related TEAEs led to treatment discontinuation in 9%. Grade 5 regorafenib-related TEAEs occurred in <1%. The most common grade ≥3 regorafenib-related TEAEs were hypertension (15%), hand-foot skin reaction (14%), fatigue (13%), diarrhea (5%), and hypophosphatemia (5%). Treatment-emergent grade 3-4 laboratory toxicities included alanine aminotransferase (6%), aspartate aminotransferase (7%), and bilirubin (13%). Ongoing monitoring identified one nonfatal case of regorafenib-related severe drug-induced liver injury per DILI Working Group criteria. Median PFS (95% confidence interval [CI]) was 2.7 months (2.6-2.7). CONCLUSION: In CONSIGN, the frequency and severity of TEAEs were consistent with the known safety profile of regorafenib. PFS was similar to reports of phase III trials. ClinicalTrials.gov: NCT01538680. IMPLICATIONS FOR PRACTICE: Patients with metastatic colorectal cancer (mCRC) who fail treatment with standard therapies, including chemotherapy and monoclonal antibodies targeting vascular endothelial growth factor or epidermal growth factor receptor, have few treatment options. The multikinase inhibitor regorafenib was shown to improve survival in patients with treatment-refractory mCRC in the phase III CORRECT (N = 760) and CONCUR (N = 204) trials. However, safety data on regorafenib for mCRC in a larger number of patients were not available. The CONSIGN trial, carried out prospectively in more than 2,800 patients across 25 countries, confirmed the safety profile of regorafenib from the phase III trials and reinforced the importance of using treatment modifications to manage adverse events.

Thrombosis, anticoagulation and outcomes in malignant superior vena cava syndrome.

Anticoagulation is often used in superior vena cava syndrome (SVCS) associated with cancer (i.e malignant SVCS), even without thrombosis, but its effect on outcomes has not been reported. We aimed to determine factors and outcomes associated with thrombosis and anticoagulation in malignant SVCS. Patients with malignant SVCS diagnosed on computerized tomography (CT) were retrospectively included, indexed at diagnosis and followed for 6 months using medical records. The cohort included 183 patients with malignant SVCS of which 153 (84%) were symptomatic. Thirty of the 127 patients (24%) with a reviewable baseline CT had thrombosis of the SVC or tributaries at diagnosis. Patients with baseline thrombosis more often had symptomatic SVCS (p < 0.01). 70% (21/30) of patients with thrombosis and 52% (49/97) of those without thrombosis at baseline received anticoagulation, most often at therapeutic doses. Thrombosis occurred in 5/39 patients with anticoagulation (13%) compared to 2/18 (11%) of those without, during follow-up (p = 0.85). Anticoagulation was associated with a reduction in risk of SVC stent placement during follow-up that did not reach statistical significance (HR 0.47, 95% CI 0.2-1.13, p = 0.09). Major bleeding occurred in 7 (4%) patients, six of whom received anticoagulation (four therapeutic and two intermediate dose). Neither thrombosis nor anticoagulation affected survival. Anticoagulation is commonly used as primary prevention but its benefit remains to be proven. The role of reduced-dose anticoagulation in non-thrombotic malignant SVCS should be prospectively assessed.

Computed Tomography Findings Associated With 30-Day Mortality in Patients With Malignant Superior Vena Cava Syndrome.

OBJECTIVE: The objective of this study was to identify radiological and clinical factors associated with early mortality in malignant superior vena cava syndrome (SVCS). MATERIALS AND METHODS: Chest computed tomography studies of 127 patients with malignancy-associated SVCS were retrospectively reviewed. Involvement of SVC and tributaries, pleural and pericardial effusions, pulmonary artery involvement, and ancillary findings were documented. Univariate and multivariate models determined associations between radiological and clinical variables, and 30-day mortality. RESULTS: Thirty-day mortality rate was 16.5% (n = 21). Factors associated with 30-day mortality on univariate analysis included age, cancer stage, SVCS clinical severity, left jugular vein obstruction, number of involved veins, pulmonary arteries involvement, and presence of pleural effusions. Age, SVCS clinical severity, number of veins involved, and pleural effusions were positively associated with 30-day mortality on multivariate analysis. CONCLUSIONS: Selected clinical and radiological variables are associated with early death in malignant SVCS. These factors may identify a subgroup of patients who may benefit from treatment escalation.

Brain metastasis in gastroesophageal adenocarcinoma and HER2 status.

The increased survival of patients with gastroesophageal adenocarcinoma (GAD) following improvements in treatment has been accompanied by a rising incidence of secondary brain metastasis. HER2 amplification/overexpression, which has been associated with an increased risk of brain metastasis in breast cancer, is found in about 20% of patients with GAD. The aim of this study was to evaluate the effect of HER2 status on brain metastasis in GAD. The database of a tertiary cancer center was searched for patients with GAD diagnosed in 2011-2015, and data were collected on clinical characteristics, brain metastasis, HER2 status, and outcome. We identified 404 patients with a confirmed diagnosis of GAD. HER2 results were available for 298: 69 (23.2%) positive and 227 negative. Brain metastasis developed in 15 patients with GAD (3.7%); HER2 results, available in 13, were positive in 6, negative in 6, and equivocal in 1. The brain metastasis rate was significantly higher in HER2-positive than HER2-negative patients with GAD (6/69, 8.7% vs. 6/227, 2.6%; RR = 3.3, 95% CI 1.1-9.9, p = 0.034). Median overall survival from diagnosis of brain metastasis was 2.3 months, with no significant difference by HER2 status. HER2 positive GAD patients may be at increased risk to develop BM. Clinicians should maintain a lower threshold for performing brain imaging in patients with HER2-positive GAD given their increased risk of brain metastasis. The role of anti-HER2 agents in the development and treatment of brain metastasis in GAD warrants further study.

The Association of Helicobacter pylori Seropositivity with All-Cause Mortality among Colorectal Cancer Patients Undergoing PET/CT Scans.

BACKGROUND: Evidence has been emerging that Helicobacter pylori may also impact colorectal cancer (CRC). Positron emission tomography/computed tomography (PET/CT) imaging can predict overall survival in CRC patients. OBJECTIVES: To determine a possible association between H. pylori seropositivity and all-cause mortality among CRC patients evaluated by PET/CT scans. METHODS: This prospective cohort study was comprised of 110 consecutive CRC patients who had undergone a PET/CT evaluation in a tertiary academic medical center. Data included demographics, body mass index (BMI), tumor node metastasis stage at diagnosis, treatment, time from diagnosis to PET/CT, and PET/CT findings. All patients were tested for anti-H. pylori immunoglobulin G (IgG) antibodies and followed for 36 months from the day of the PET/CT scan. Mortality was documented. Univariate and multivariate Cox regression was used to estimate the hazard ratio (HR) of H. pylori serological status. RESULTS: During the follow-up period, of the 110 CRC patients 41 (37.3%) died and 69 (62.7%) survived. Of the 41 patients, 26 (63.4%) were H. pylori seropositive and 15 (36.6%) were seronegative. Multivariate analysis showed that H. pylori seropositivity was associated with increased mortality (HR 3.46, 95% confidence interval 1.63-7.32), stage IV at diagnosis, metastatic disease found on PET/CT, longer time from diagnosis to PET/CT, lower BMI, and older age. CONCLUSIONS: Our findings suggest that H. pylori infection may be a risk factor for all-cause mortality among CRC patients who are evaluated by PET/CT. Multicenter studies with larger patient groups are needed to confirm our findings.

Bevacizumab for Metastatic Colorectal Cancer: A Global Cost-Effectiveness Analysis.

BACKGROUND: In the U.S., the addition of bevacizumab to first-line chemotherapy in metastatic colorectal cancer (mCRC) has been demonstrated to provide 0.10 quality-adjusted life years (QALYs) at an incremental cost-effectiveness ratio (ICER) of $571,000/QALY. Due to variability in pricing, value for money may be different in other countries. Our objective was to establish the cost-effectiveness of bevacizumab in mCRC in the U.S., U.K., Canada, Australia, and Israel. METHODS: We performed the analysis using a previously established Markov model for mCRC. Input data for efficacy, adverse events, and quality of life were considered to be generalizable and therefore identical for all countries. We used country-specific prices for medications, administration, and other health service costs. All costs were converted from local currency to U.S. dollars at the exchange rates in March 2016. We conducted one-way and probabilistic sensitivity analyses (PSA) to assess the model robustness across parameter uncertainties. RESULTS: Base case results demonstrated that the highest ICER was in the U.S. ($571,000/QALY) and the lowest was in Australia ($277,000/QALY). In Canada, the U.K., and Israel, ICERs ranged between $351,000 and $358,000 per QALY. PSA demonstrated 0% likelihood of bevacizumab being cost-effective in any country at a willingness to pay threshold of $150,000 per QALY. CONCLUSION: The addition of bevacizumab to first-line chemotherapy for mCRC consistently fails to be cost-effective in all five countries. There are large differences in cost-effectiveness between countries. This study provides a framework for analyzing the value of a cancer drug from the perspectives of multiple international payers. IMPLICATIONS FOR PRACTICE: The cost-effectiveness of bevacizumab varies significantly between multiple countries. By conventional thresholds, bevacizumab is not cost-effective in metastatic colon cancer in the U.S., the U.K., Australia, Canada, and Israel.

The association between smoking and breast cancer characteristics and outcome.

BACKGROUND: Smoking is associated with an increased incidence of hormone receptor positive breast cancer. Data regarding worse breast cancer outcome in smokers are accumulating. Current literature regarding the impact of smoking on breast cancer characteristics is limited. We evaluated the impact of smoking on breast cancer characteristics and outcome. METHODS: This was a retrospective single center study. All women diagnosed from 4/2005 through 3/2012 and treated in our institute for early, estrogen receptor positive, human epidermal growth factor receptor 2 (HER2) negative breast cancer, whose tumors were sent for Oncotype DX analysis were included. Medical records were reviewed for demographics, clinico-pathological parameters, treatment and outcome. Data regarding smoking were retrieved according to patients' history at the first visit in the oncology clinic. Patients were grouped and compared according to smoking history (ever smokers vs. never smokers), smoking status (current vs. former and never smokers) and smoking intensity (pack years ≥30 vs. the rest of the cohort). Outcomes were adjusted in multivariate analyses and included age, menopausal status, ethnicity, tumor size, nodal status and grade. RESULTS: A total of 662 women were included. 28.2% had a history of smoking, 16.6% were current smokers and 11.3% were heavy smokers. Smoking had no impact on tumor size, nodal involvement and Oncotype DX recurrence score. Angiolymphatic and perineural invasion rates were higher in current smokers than in the rest of the cohort (10.4% vs. 5.1%, p = 0.045, 8.3% vs. 3.5%, p = 0.031, respectively). Smoking had no other impact on histological characteristics. Five-year disease free survival and overall survival rates were 95.7% and 98.5%, respectively. Smoking had no impact on outcomes. Adjusted disease free survival and overall survival did not influence the results. CONCLUSIONS: Smoking had no clinically significant influence on tumor characteristics and outcome among women with estrogen receptor positive, HER2 negative, early breast cancer. As the study was limited to a specific subgroup of the breast cancer population in this heterogeneous disease and since smoking is a modifiable risk factor for the disease, further research is required to clarify the possible impact of smoking on breast cancer.

[FERTILITY PRESERVATION IN YOUNG CANCER PATIENTS - CAN WE OPTIMIZE THE PATH?]

INTRODUCTION: Advances in cancer therapy have improved the long-term survival of cancer patients. Concerns about fertility represent a major issue for young cancer patients. The emergent discipline of oncofertility, an intersection between oncology and fertility, is a new concept that describes an integrated network of clinical resources that focus on fertility preservation from both clinical and research perspectives. Patients and methods: In this article we describe our designated multidisciplinary program for fertility preservation in pediatric and young adult populations. The program is also designed to serve as a prospective platform for the evaluation of reproductive outcomes in this patient cohort. RESULTS: We have observed considerably higher referral rates following launching the program and earlier referral of chemonaïve patients that concedes maximal fertility preservation. Two hundred and thirty five patients were referred to the program over a period of 3 years. CONCLUSIONS: Our program demonstrates that multidisciplinary programs that encompass relevant specialists, skilled laboratory resources and a facilitated path that drives the process in the shortest time, maximizes the yield.

The Association between Angiotensin Receptor Blocker Usage and Breast Cancer Characteristics.

PURPOSE: To evaluate the association between angiotensin receptor blocker (ARB) usage and breast cancer characteristics and outcomes. METHODS: All patients who were treated in our institute for estrogen receptor-positive, human epidermal growth factor receptor 2-negative early breast cancer between April 2005 and March 2012 and whose tumors were sent for Oncotype-DX analysis were included. Medical records were retrospectively reviewed. Data regarding ARB usage were retrieved. Usage of several prespecified medications for hypertension was also evaluated. Each medication group was compared with the rest of the cohort. RESULTS: A total of 671 patients were included. Forty-six (7%) patients were treated with ARB. ARB usage was associated with macroscopic nodal involvement (p < 0.001) and a more advanced stage at diagnosis (p < 0.001). These findings remained significant in the multivariate analysis. Patients treated with ARB also had a higher incidence of invasive lobular carcinoma subtype (p = 0.009), a worse 5-year breast cancer-specific survival (94.7 vs. 98.8%, p = 0.024) and a worse 5-year overall survival (94.6 vs. 98.8%, p = 0.015), but these differences were not demonstrated in the multivariate analysis. CONCLUSIONS: Patients treated with ARB presented with a more advanced breast cancer disease and some distinct histological features. Further research is required to elucidate the effect of ARB treatment on breast cancer.

Impact of the 12-Gene Colon Cancer Assay on Clinical Decision Making for Adjuvant Therapy in Stage II Colon Cancer Patients.

OBJECTIVES: To evaluate the impact of the 12-gene Colon Cancer Recurrence Score Assay-a clinically validated prognosticator in stage II colon cancer after surgical resection-on adjuvant treatment decisions in T3 mismatch repair proficient (MMR-P) stage II colon cancer in clinical practice. METHODS: This retrospective analysis included all patients with T3 MMR-P stage II colon cancer (Clalit Health Services members) with Recurrence Score results (time frame January 2011 to May 2012). Treatment recommendations pretesting were compared with the treatments received. Changes were categorized as decreased (to observation alone/removing oxaliplatin from the therapy) or increased (from observation alone/adding oxaliplatin to the therapy) intensity. RESULTS: The analysis included 269 patients; 58%, 32%, and 10% of the values were in the low (<30), intermediate (30-40), and high (≥41) score groups, respectively. In 102 patients (38%), treatment changed post-testing (decreased/increased intensity 76/26 patients). The overall impact was decreased chemotherapy use (45.0% to 27.9%; P < 0.001). Treatment changes occurred in all score groups, but more frequently in the high (change rate 63.0%; 95% confidence interval [CI] 42.3%-80.6%) than in the intermediate (30.6%; 95% CI 21.0%-41.5%) and low (37.6%; 95% CI 30.0%-45.7%) score groups. The direction of the change was consistent with the assay result, with increased intensity more common in higher score values and decreased intensity more common in lower score values. CONCLUSIONS: Testing significantly affected adjuvant treatment in T3 MMR-P stage II colon cancer in clinical practice. The study is limited by its design, which compared treatment recommendations pretesting to actual treatments received post-testing, lack of a control group, and nonassessment of confounding factors that may have affected treatment decisions.

Colorectal cancer in young patients: is it a distinct clinical entity?

BACKGROUND: The incidence of colorectal cancer in young patients is increasing. It remains unclear if the disease has unique features in this age group. METHODS: This was a single-center, retrospective cohort study which included patients diagnosed with colorectal cancer at age ≤40 years in 1997-2013 matched 1:2 by year of diagnosis with consecutive colorectal cancer patients diagnosed at age >50 years during the same period. Patients aged 41-50 years were not included in the study, to accentuate potential age-related differences. Clinicopathological characteristics, treatment, and outcome were compared between groups. RESULTS: The cohort included 330 patients, followed for a median time of 65.9 months (range 4.7-211). Several significant differences were noted. The younger group had a different ethnic composition. They had higher rates of family history of colorectal cancer (p = 0.003), hereditary colorectal cancer syndromes (p < 0.0001), and inflammatory bowel disease (p = 0.007), and a lower rate of polyps (p < 0.0001). They were more likely to present with stage III or IV disease (p = 0.001), angiolymphatic invasion, signet cell ring adenocarcinoma, and rectal tumors (p = 0.02). Younger patients more frequently received treatment. Young patients had a worse estimated 5-year disease-free survival rate (57.6  vs. 70 %, p = 0.039), but this did not retain significance when analyzed by stage (p = 0.092). Estimated 5-year overall survival rates were 59.1 and 62.1 % in the younger and the control group, respectively (p = 0.565). CONCLUSIONS: Colorectal cancer among young patients may constitute a distinct clinical entity. Further research is needed to validate our findings and define the optimal approach in this population.

Perception of prognosis of cancer patients by non-oncologists.

BACKGROUND: Data are lacking regarding the perception of cancer patients' prognosis by physicians who are not oncologists. METHODS: This was a multicenter survey of seven university-affiliated hospitals, assessing physicians' perception of the median survival of patients with seven advanced malignancies. The study cohort included physicians from all 73 internal medicine, surgery, emergency medicine and critical care departments in the participating hospitals. Family practitioners were contacted through email. Physicians' specialty, age, professional status and hospital type (secondary vs tertiary) were noted. The primary end-point was defined as the percentage of answers with a pessimistic error of more than a year in perception of prognosis as compared with current literature. The secondary end-point was defined as any pessimistic answer. RESULTS: Four hundred and eighty-eight physicians filled the questionnaire, including 429 hospital physicians and 59 family practitioners. Perception of prognosis was pessimistic when compared with current literature, with 37% and 59% of the answers meeting the primary and the secondary end-points, respectively. Younger age, resident status and work at a secondary hospital were associated with pessimistic perception (P<.001 for all variables). Pessimistic outlook was similar for all specialties and for most malignancies, including those with considerable cure rates such as Hodgkin's lymphoma and germ cell tumour. CONCLUSION: Non-oncologists are considerably over pessimistic regarding their perception of the cancer patients' prognosis. A pessimistic perception of prognosis might cause undertreatment and therefore affect both patients' quality of life and their actual survival. Education regarding cancer therapy and its benefits should be emphasised for non-oncologists involved in cancer patient care.
