RESUMEN

Current guidelines recommend that clinically staged T1N0 esophageal cancers are to be referred to surgery or endoscopic resection. Using the National Cancer Database, we identified 733 individuals with clinically staged T1N0 esophageal carcinoma, who underwent upfront surgery and did not receive any prior treatment. We assessed upstaging, which was defined as ≥ T2 disease or positive lymph nodes. Poorly differentiated adenocarcinomas were associated with upstaging, whereas squamous cell carcinomas were not. Specifically, the percentage of upstaging among individuals with clinically staged T1b and poorly differentiated tumor was 33.8%. Therefore, clinically staged T1bN0 poorly differentiated esophageal adenocarcinomas are at high risk for upstaging following surgery.

RESUMEN

BACKGROUND: Small-bowel obstruction (SBO) after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is a common complication associated with re-admission that may alter patients' outcomes. Our aim was to characterize and investigate the impact of bowel obstruction on patients' prognosis. METHODS: This was a retrospective analysis of patients with SBO after CRS/HIPEC (n = 392). We analyzed patients' demographics, operative and perioperative details, SBO re-admission data, and long-term oncological outcomes. RESULTS: Out of 366 patients, 73 (19.9%) were re-admitted with SBO. The cause was adhesive in 42 (57.5%) and malignant (MBO) in 31 (42.5%). The median time to obstruction was 7.7 months (range, 0.5-60.9). Surgical intervention was required in 21/73 (28.7%) patients. Obstruction eventually resolved (spontaneous or by surgical intervention) in 56/73 (76.7%) patients. Univariant analysis identified intraperitoneal chemotherapy agents: mitomycin C (MMC) (HR 3.2, p = 0.003), cisplatin (HR 0.3, p = 0.03), and doxorubicin (HR 0.25, p = 0.018) to be associated with obstruction-free survival (OFS). Postoperative complications such as surgical site infection (SSI), (HR 2.2, p = 0.001) and collection (HR 2.07, p = 0.015) were associated with worse OFS. Multivariate analysis maintained MMC (HR 2.9, p = 0.006), SSI (HR 1.19, p = 0.001), and intra-abdominal collection (HR 2.19, p = 0.009) as independently associated with OFS. While disease-free survival was similar between the groups, overall survival (OS) was better in the non-obstruction group compared with the obstruction group (p = 0.03). CONCLUSIONS: SBO after CRS/HIPEC is common and complex in management. Although conservative management was successful in most patients, surgery was required more frequently in patients with MBO. Patients with SBO demonstrate decreased survival.

RESUMEN

INTRODUCTION: An increasing proportion of elderly patients (EP) are undergoing Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS/HIPEC). They have increased comorbidities and perioperative risk. Current literature is deficient in describing the outcomes of EP undergoing CRS/HIPEC. MATERIALS AND METHODS: A retrospective review of our prospectively maintained CRS/HIPEC database analyzed perioperative and oncological outcomes of EP (>70 y) compared to younger patients (YP) (<60 y). RESULTS: Of 500 CRS/HIPEC patients, 62 EP and 210 YP were included. Median age was 73 y in EP and 46 y in YP. Demographic, clinical, operative, and perioperative outcomes were similar between groups. American Society of Anesthesiologists > 3 was more prevalent in the EP with 88.2% versus 54.8% in the YP (P < 0.001). Comorbidities were higher in the EP with 87.1% versus 39.0% in the YP (P < 0.001). Peritoneal Cancer Index score was similar with a median of 9. All postoperative and severe complications were similar with 55.2% and 17.1% in the YP and 64.5% and 21.0% in the EP (P = 0.242; P = 0.448). Postoperative mortality was similar with 1.5% in the YP and 5.0% in the EP (P = 0.134). In colorectal primary patients, median overall and disease-free survival was 61.8 and 12.9 mo in the YP and 64.6 and 11.3 mo in the EP (P = 0.363; P = 0.845). CONCLUSIONS: Despite a significant age difference, increased comorbidities, worse American Society of Anesthesiologists, and similar Peritoneal Cancer Index burden, we found no significant differences in perioperative complications or oncological benefit in elderly CRS/HIPEC patients. EP appear to have similar perioperative and oncological outcomes as YP.

RESUMEN

BACKGROUND: Current guidelines recommend neoadjuvant chemotherapy in patients with locoregional gastric adenocarcinoma. Patients diagnosed with early stage gastric adenocarcinoma are usually managed with upfront surgical intervention. However, pathologic staging in a subset of these clinically staged patients identifies more advanced locoregional disease requiring adjuvant treatment. Therefore, identifying these patients prior to surgical intervention is critical to ensure employment of the appropriate treatment paradigm. The aim of the current study was to define patient characteristics associated with clinical understaging in early gastric cancer. METHODS: Using the National Cancer Database (2004-2014) we identified 3,892 individuals with clinical T1N0 gastric adenocarcinoma who underwent upfront definitive surgery, had negative surgical margins, and did not receive preoperative chemotherapy or radiotherapy. Patient characteristics were compared between those with pathologic stage T1N0 disease and those who were upstaged upon surgery. RESULTS: Twenty-seven percent of clinical T1N0 gastric adenocarcinomas had a change in stage because of pathologically defined ≥T2 disease or positive lymph nodes. Individuals who were upstaged had a higher tumor grade compared with those with pathologic stage T1N0 disease. Specifically, 41.9% (530/1,264) of individuals with a poorly differentiated tumor were upstaged, compared with only 10.7% (70/656) with a well-differentiated tumor. Approximately 75% of cases involved upstaging because of T misclassification. The highest percentage of upstaging was shown for tumors located at the fundus and body of the stomach. CONCLUSION: Upstaging of clinical T1N0 gastric adenocarcinoma is characterized by higher tumor grade and is mostly a result of a change in T stage. These findings mandate thorough workup in order to identify patients with clinically staged T1N0 disease requiring preoperative chemotherapy. IMPLICATIONS FOR PRACTICE: Upstaging of clinical T1N0 gastric adenocarcinoma is characterized by higher tumor grade and is mostly a result of a change in T stage. These findings mandate thorough workup in order to identify patients with clinically staged T1N0 disease requiring preoperative chemotherapy.

RESUMEN

BACKGROUND: Cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) for colorectal cancer peritoneal metastases (CRPM) is associated with improved survival in patients with historically dismal prognosis. Nonetheless, peritoneal recurrences remain common and represent a difficult challenge in these patients' management. Repeat CRS/HIPEC is associated with even greater morbidity and its survival benefit has not yet been clearly demonstrated. METHODS: We retrospectively reviewed our prospectively maintained database and aimed to assess the safety and oncological efficacy of repeat CRS/HIPEC. RESULTS: Two hundred thirty-two patients underwent an initial CRS/HIPEC, whereas 30 subsequently had repeat CRS/HIPEC for CRPM. Groups were similar in demographics, comorbidities, and peritoneal cancer index (PCI). No significant difference in morbidity, hospital stay, or reoperation rate was noted between initial and repeat procedures. Patients who underwent repeat CRS/HIPEC had a median overall survival of 68 months versus 51 months in patients who did not undergo repeat procedure for their peritoneal recurrence (p = 0.03). Disease-free survival (DFS) in patients after repeat and after initial procedure were similar with median of 9.6 versus 12 months, respectively (p = 0.083). Univariate analysis demonstrated that PCI, DFS, and repeat procedure displayed significant factors on outcomes in patients with peritoneal recurrences, whereas PCI > 16 and DFS remained independent predictors on multivariable analysis. CONCLUSIONS: Our analysis, which represents the largest series to date of repeat CRS/HIPEC for CRPM, indicates that this approach as a part of multimodal therapy is both safe and efficacious in appropriately selected patients.

RESUMEN

BACKGROUND: Synchronous peritoneal and liver metastasis in colorectal cancer is a relative contraindication for curative surgery. We aimed to evaluate the safety and oncological outcomes of combined treatment of peritoneal and liver metastasis. METHODS: We conducted a retrospective analysis of metastatic colorectal cancer patients from two prospective databases: peritoneal surface malignancy (n = 536) and hepatobiliary (n = 286). We compared 60 patients treated with cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) and hepatectomy; 80 patients treated with cytoreduction and HIPEC only; and 63 patients treated with hepatectomy alone. RESULTS: No differences in demographics were observed between the groups. Median hospital and intensive care unit (ICU) stay was shorter in group C (7 and 1 days, respectively) versus groups A and B (13 and 1 days, and 12 and 1 days, respectively; p < 0.001). Postoperative complications were not significantly different. Median follow-up was 18.6, 23.1, and 30.6 months for groups A, B, and C, respectively. Estimated 5-year overall survival (OS) was 48.8% (group A), 55.4% (group B), and 60.2% (group C) [p = 0.043 for group A vs. group C], and estimated 5-year disease-free survival (DFS) was 14.2% (group A), 23.0% (group B), and 18.6% (group C). Five-year OS was superior in group C compared with group A (p = 0.043), and DFS was superior in group C compared with groups A and B (p = 0.043 and 0.03, respectively). The peritoneum was the site of first recurrence in groups A and B (23.3% and 32.5%, respectively), and the liver was the site of first recurrence in group C (44.4%). CONCLUSIONS: We report favorable perioperative and oncological outcomes in combined cytoreduction/HIPEC and hepatectomy for patients with peritoneal and liver metastasis. Surgical intervention after multidisciplinary discussion should be considered in patients with both peritoneal and hepatic lesions when complete cytoreduction is feasible.

RESUMEN

BACKGROUND: Pathological response of colorectal peritoneal metastasis (CRPM) may affect prognosis. We investigated the relationship between oncological outcomes and pathological response to chemotherapy of CRPM following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: We conducted a retrospective analysis of a prospectively maintained Peritoneal Surface Malignancies database between 2015 and 2020. Analysis included patients with CRPM who underwent a CRS/HIPEC procedure (n = 178). The cohort was divided into three groups according to the response ratio (ratio of tumor-positive specimens to the total number of specimens resected): Group A, complete response; Group B, high response ratio, and Group C, low response ratio. RESULTS: The group demographics were similar, but the overall complication rate was higher in Group C (65.2%) compared with Groups A (55%) and B (42.8%) [p = 0.03]. Survival correlated to response ratio; the estimated median disease-free survival of Group C was 9.1 months (5.97-12.23), 14.9 months (4.72-25.08) for Group B, and was not reached in Group A (p = 0.001). The estimated median overall survival in Group C was 35 months (26.69-43.31), and was not reached in Groups A and B (p = 0.001). CONCLUSIONS: The pathological response ratio to systemic therapy correlates with survival in patients undergoing CRS/HIPEC. This study supports the utilization of preoperative therapy for better patient selection, with a potential impact on survival.

RESUMEN

BACKGROUND: Neoadjuvant FOLFIRINOX is a standard-of-care treatment for BRPC patients. Patients with gBRCAm who have demonstrated improved response to platinum-based chemotherapy may have impaired homologous repair deficiency. This study aimed to describe the pathologic complete response rate and long-term survival for patients with germline BRCA1 or BRCA2 mutation (gBRCAm) and borderline resectable pancreatic cancer (BRPC) treated with neoadjuvant FOLFIRINOX. METHODS: A dual-center retrospective analysis was performed. Patients who had BRPC treated with neoadjuvant FOLFIRINOX followed by curative resection were identified from clinical databases. Pathologic complete response was defined as no viable tumor cells present in the specimen. Common founder Jewish germline BRCA1 or BRCA2 mutation was determined for available patients. RESULTS: The 61 BRPC patients in this study underwent resection after neoadjuvant FOLFIRINOX. Analysis of BRCA mutation was performed for 39 patients, and 9 patients were found to be BRCA2 germline mutation carriers. The pathologic complete response rate was 44.4% for the gBRCAm patients and 10% for the BRCA non-carriers (p = 0.009). The median disease-free survival was not reached for the gBRCAm patients and was 7 months for the BRCA non-carriers (p = 0.03). The median overall survival was not reached for the gBRCAm patients and was 32 months for the BRCA non-carriers (p = 0.2). After a mean follow-up period of 33.7 months, all eight patients with pathologic complete response were disease-free. CONCLUSIONS: The study showed that gBRCAm patients with BRPC have an increased chance for pathologic complete response and prolonged survival after neoadjuvant FOLFIRINOX. The results support the benefit of exposing gBRCAm patients to platinum-based chemotherapy early in the course of the disease. Neoadjuvant FOLFIRINOX should be considered for BRCA carriers who have resectable pancreatic cancer.

RESUMEN

PURPOSE: Both ß1- and ß2-adrenoceptor proteins were detected on the cell surface of pancreatic ductal adenocarcinoma. The current study evaluated the association between beta-blocker use and pancreatic cancer risk. METHODS: We conducted a nested case-control study in a large population representative database. Each pancreatic cancer case was matched with four controls based on age, sex, practice site, and duration of follow-up using incidence density sampling. Beta-blocker use was defined as any prescription prior to index date and was stratified into non-selective and selective ß1 -blockers. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for pancreatic cancer risk associated with beta-blocker use was estimated using conditional logistic regression. RESULTS: The study included 4113 patients with pancreatic cancer and 16 072 matched controls. When compared to never users, there was no association between any beta-blocker use and pancreatic cancer risk (adjusted OR 1.06, 95% CI 0.97-1.16, P = .16). Analysis by receptor selectivity showed use of non-selective beta-blockers for more than 2 years was associated with a reduced pancreatic cancer risk (OR 0.75, 95% CI 0.57-1.00, P = .05). When compared to former users both users of selective ß1-blockers and non-selective beta-blockers had a reduced pancreatic cancer risk (OR 0.78, 95% CI 0.67-0.90, P = .001) and (OR 0.67, 95% CI 0.49-0.92, P = .01), respectively. CONCLUSION: Beta-blocker use was not associated with increased pancreatic cancer risk. However, long-term use of beta-blockers may be associated with decreased pancreatic cancer risk.

RESUMEN

BACKGROUND: Patients with advanced gastric or gastro-oesophageal junction cancer that progresses on chemotherapy have poor outcomes. We compared pembrolizumab with paclitaxel in patients with advanced gastric or gastro-oesophageal junction cancer that progressed on first-line chemotherapy with a platinum and fluoropyrimidine. METHODS: This randomised, open-label, phase 3 study was done at 148 medical centres in 30 countries. Eligible patients were randomised (1:1) in blocks of four per stratum with an interactive voice-response and integrated web-response system to receive either pembrolizumab 200 mg every 3 weeks for up to 2 years or standard-dose paclitaxel. Primary endpoints were overall survival and progression-free survival in patients with a programmed cell death ligand 1 (PD-L1) combined positive score (CPS) of 1 or higher. Safety was assessed in all patients, irrespective of CPS. The significance threshold for overall survival was p=0·0135 (one-sided). This trial is registered at ClinicalTrials.gov, number NCT02370498. FINDINGS: Between June 4, 2015, and July 26, 2016, 592 patients were enrolled. Of the 395 patients who had a PD-L1 CPS of 1 or higher, 196 patients were assigned to receive pembrolizumab and 199 patients were assigned to receive paclitaxel. As of Oct 26, 2017, 326 patients in the population with CPS of 1 or higher had died (151 [77%] of 196 patients in the pembrolizumab group and 175 [88%] of 199 patients in the paclitaxel group). Median overall survival was 9·1 months (95% CI 6·2-10·7) with pembrolizumab and 8·3 months (7·6-9·0) with paclitaxel (hazard ratio [HR] 0·82, 95% CI 0·66-1·03; one-sided p=0·0421). Median progression-free survival was 1·5 months (95% CI 1·4-2·0) with pembrolizumab and 4·1 months (3·1-4·2) with paclitaxel (HR 1·27, 95% CI 1·03-1·57). In the total population, grade 3-5 treatment-related adverse events occurred in 42 (14%) of the 294 patients treated with pembrolizumab and 96 (35%) of the 276 patients treated with paclitaxel. INTERPRETATION: Pembrolizumab did not significantly improve overall survival compared with paclitaxel as second-line therapy for advanced gastric or gastro-oesophageal junction cancer with PD-L1 CPS of 1 or higher. Pembrolizumab had a better safety profile than paclitaxel. Additional trials of pembrolizumab in gastric and gastro-oesophageal cancer are ongoing.

RESUMEN

BACKGROUND: Current guidelines include the use of adjuvant oxaliplatin in clinical stage II or III rectal adenocarcinoma. However, its efficacy is supported by a single phase II trial. We aimed to examine whether oxaliplatin confers survival benefit in this patient population. METHODS: Using the National Cancer Database (2006-2013) we identified 6,868 individuals with clinical stage II or III rectal adenocarcinoma treated with neoadjuvant chemoradiotherapy, surgery, and adjuvant chemotherapy. We used multivariate Cox regression to evaluate survival differences according to treatment intensity and change from clinical to pathological stage. RESULTS: We demonstrated an association with improved overall survival with the use of doublet adjuvant chemotherapy in pathological stage III rectal adenocarcinoma (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.67-0.92). This association was confirmed in patients with clinical stage III and subsequent pathological stage III disease (HR, 0.69; 95% CI, 0.57-0.83) and was not observed in patients who progressed from clinical stage II to pathological stage III disease. Doublet adjuvant chemotherapy was not associated with improved overall survival in patients with pathological stage 0 or I disease, regardless of their clinical stage. CONCLUSION: Adjuvant oxaliplatin following neoadjuvant chemoradiotherapy in rectal adenocarcinoma was confirmed in patients with clinical stage III and subsequent pathological stage III disease. Omission of oxaliplatin can be considered in pathological complete response or pathological stage I disease. IMPLICATIONS FOR PRACTICE: Current guidelines include the use of oxaliplatin as part of adjuvant chemotherapy (AC) in patients with clinical stage II or III rectal adenocarcinoma (RAC). However, its efficacy is supported only by a single phase II trial. This study found an association with improved overall survival with the use of doublet AC in patients diagnosed with clinical stage III and subsequent pathological stage III, and not in patients with pathological stage 0 or I, regardless of their clinical stage. Therefore, omission of oxaliplatin can be considered in patients with either pathological complete response or pathological stage I RAC, thereby avoiding oxaliplatin-induced neuropathy.

RESUMEN

PURPOSE: Acneiform rash, a common toxicity of epidermal growth factor receptor inhibitors (EGFRIs), can cause patient discomfort, warranting changes in treatment. This study investigated the safety, tolerability, and efficacy of a novel doxycycline foam, FDX104 4%, for managing EGFRI-related skin toxicity. METHODS: This was an exploratory phase 2, randomized, double-blind, placebo-controlled study. Subjects had metastatic colorectal cancer and were being treated with either cetuximab or panitumumab plus chemotherapy. Treatment (twice-daily topical FDX104 4% on one side of the face and vehicle foam on the other for 5 weeks) was initiated 7 ± 3 days prior to EGFRI therapy. Rash severity, safety, and tolerability were evaluated at 2 and 4 weeks after EGFRI start. RESULTS: The mean maximal rash grade was lower with FDX104 4% vs vehicle, and fewer subjects developed moderate-to-severe (grades 2-3) rash. On the Global Severity Score scale, a statistically significant difference favored FDX104 4% over vehicle (P = .047). Adverse events (AEs) (n = 68) occurred in 20 subjects; most were mild or moderate. The most common AEs were oral mucositis, nausea, and vomiting, common to chemotherapy and EGFRI treatment. Study-drug-related AEs were experienced by five subjects and consisted of mild, local skin reactions. No study-drug-related systemic side effects were reported. CONCLUSION: Twice-daily, topical administration of FDX104 4% as an adjunct to either cetuximab or panitumumab was safe and well tolerated, and appeared to prevent the onset of rash, especially severe rash.

RESUMEN

OBJECTIVES: Contextual self-concealment in the psychooncology literature has been found to be associated with elevated distress. The current study aimed to understand the dyadic relationships of an individual's perception of spousal support and dispositional perspective-taking with own and partner's levels of self-concealment behavior, among couples coping with cancer. METHODS: A subsample of 61 heterosexual couples coping with cancer was taken from a large-scale cross-sectional study. Patients and their spouses independently completed measures of perceived spousal support, perspective-taking, and contextual self-concealment. Dyadic data were analyzed by using the actor-partner interdependence model both for couples in which the woman was the patient and also for couples in which the man was the patient. RESULTS: Perceived spousal support negatively predicted contextual self-concealment, regardless of gender and role. Implications of perspective-taking for concealment behavior were dependent on role and gender. A female patient's perspective-taking was associated with a reduction in her own and her spouse's concealment behavior. A male spouse's perspective-taking was associated with an increase in his own and his spouse's concealment behavior. A female spouse's perspective-taking negatively predicted patient's concealment behavior, but not her own. CONCLUSIONS: Findings stress the important roles played by spousal support and perspective-taking in communication patterns between couples affected by cancer. Although the perception of support from one's spouse seems to reduce the need to conceal cancer-related issues, interventions that focus on couples' communication should address the differential implications of perspective-taking, as they can lead to either more or less self-concealment among couples, depending on role and gender.

RESUMEN

Data regarding cancer risk for individuals who were exposed to traumatic and stressful life events are conflicting. We sought to evaluate the association between posttraumatic stress disorder (PTSD) and the risk of the four most common solid tumors: lung, breast, prostate, and colorectal cancers. We conducted four nested case-control studies using a large UK population-based database. Cases were defined as individuals with any medical code for the specific malignancy. For every case, we used incidence-density sampling to match four controls by age, sex, practice site, and both duration and calendar time of follow-up. Exposure of interest was any diagnosis of PTSD prior to cancer diagnosis. The odds ratios (ORs) and 95% confidence intervals (CIs) for cancer risk associated with PTSD were estimated using multivariable conditional logistic regression and were adjusted for smoking status, obesity, and antidepressant use. The study population included four case groups according to cancer type. There were 19,143 cases with lung cancer (74,473 matched controls), 22,163 cases with colorectal cancer (86,538 matched controls), 31,352 cases with breast cancer (123,285 matched controls), and 27,212 cases with prostate cancer (105,940 matched controls). There was no statistically significant association between PTSD and cancer risk among any of the cancer types: lung, OR = 0.73, 95% CI [0.43, 1.23]; breast, OR = 0.73, 95% CI [0.52, 1.01]; prostate, OR = 1.24, 95% CI [0.87, 1.77]; and colorectal, OR = 1.05, 95% CI [0.68, 1.62]. Our findings indicated that participants in our study with PTSD were not at increased risk of lung, breast, prostate, and colorectal cancers.

RESUMEN

ABSTRACTObjective:Both trait and contextual self-concealment, as well as shame- and guilt-proneness, have previously been found to be associated with psychological distress. However, findings regarding the associations between these variables among patients with cancer and among the spouses of patients with cancer are limited. The aim of the current study was therefore to investigate the relationship between shame-proneness and psychological distress (anxiety and depression) by examining the mediating role of both trait and contextual self-concealment among patients with cancer and among the spouses of patients with cancer. METHOD: The current study was part of a large-scale cross-sectional study on self-concealment among patients with cancer and spouses of patients with cancer. It was based on two independent subsamples: patients with cancer and spouses of patients with cancer, who were not dyads. A total of 80 patients with cancer and 80 spouses of (other) patients with cancer completed questionnaires assessing shame- and guilt-proneness, trait and contextual self-concealment, anxiety, and depression. RESULTS: Results indicate that spouses reported both greater shame-proneness and anxiety than did patients (main effect of role). Female participants reported greater shame-proneness, higher levels of contextual self-concealment, and greater depression and anxiety than did male participants (main effect of gender). No group differences (role/gender) were found for guilt-proneness and trait self-concealment. Trait and contextual self-concealment partially mediated the relationship between shame-proneness and distress, pointing out the need to further examine additional mediators. SIGNIFICANCE OF RESULTS: Findings suggest that contextual self-concealment and shame-proneness are important variables to consider when assessing distress in the setting of psycho-oncology. Study results may have significant clinical implications regarding the need to identify patients and spouses who are more prone to shame and self-concealment behavior in order to better tailor interventions for them.

RESUMEN

Background: During the past 2 decades, numerous clinical trials have focused on improving outcomes in patients with metastatic pancreatic cancer (mPDAC). The efficacy of new treatments has been demonstrated among highly selected patients in randomized phase III trials; hence, it is not clear to what extent these advances are reflected within the broader mPDAC population. Materials and Methods: Survival statistics were extracted from the SEER database for patients diagnosed with mPDAC between 1993 and 2013. Survival was analyzed using the Kaplan-Meier method and proportional hazard models. Results: The study population consisted of 57,263 patients diagnosed with mPDAC between 1993 and 2013; 52% were male, with a median age of 69 years (range, 15-104). Superior prognosis correlated with younger age, being married, tumor located within the head of the pancreas, lower grade disease, and more recent year of diagnosis. Median overall survival (OS) remained stable at 2 months between 1993 and 2013. Improvements in OS were seen for younger patients (age <50 years) and those with a more recent year of diagnosis (2009-2013). The percentage of patients who died within 2 months of initial diagnosis decreased between 1993 and 2013 (from 63.5% to 50.6%; P<.0001). The percentage of patients surviving ≥12 months improved from 4.9% in 1993 to 12.7% in 2013 (P<.0001). Conclusions: In recent years a modest improvement in OS has been seen among younger patients with mPDAC. The percentage of patients living beyond 1 year has significantly increased over time; however, the percentage of those dying within 2 months remains substantial.

RESUMEN

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.

RESUMEN

BACKGROUND: Malignant colonic obstruction is commonly treated surgically. Colonic stents are a therapeutic option for palliation or used as a bridge to surgery or chemotherapy. OBJECTIVE: The aim of the study was to evaluate the clinical success rate of stenting as a bridge to one-step surgery, chemotherapy, or as a palliative measure. DESIGN: This was a retrospective observational study. SETTINGS: The study was conducted at a university-affiliated tertiary referral center. PATIENTS AND INTERVENTIONS: From 2007 to 2014, 45 patients with malignant colonic obstruction were referred for stent insertion. MAIN OUTCOME MEASURES: Patients were grouped according to three pre-defined treatment goals: group 1: restorative one-step procedure without an ostomy, group 2: completion of scheduled chemotherapy before surgery, and group 3: palliation without surgical intervention. RESULTS: Group 1 included 11 patients. Three patients (27.3 %) met the treatment goal of one-step surgery. Eight patients (72.7 %) did not reach the primary goal due to stent insertion failure (four patients), stent-related complications (two patients), and failure to perform a one-step surgery after successful stent insertion (two patients). Group 2 included 12 patients. Chemotherapy was successfully completed prior to surgery in six patients (50 %). Six patients (50 %) did not achieve treatment goal due to stent insertion failure (two patients), stent migration (two patients), stent-related perforation (one patient), and mortality (one patient). Group 3 included 20 patients. Long-term palliation without surgical intervention was achieved in eight patients (40 %). Stent insertion failed in seven patients (35 %). Five patients (25 %) needed urgent surgery due to stent complications (three migrations and two perforations). LIMITATIONS: The study was limited by its retrospective nature and small sample size. CONCLUSIONS: This study demonstrates only a modest success rate of colonic stents in the treatment of malignant colonic obstruction. Although colonic stenting seems to be an effective method of relieving colonic obstruction, high failure rates limits its applicability.

RESUMEN

PURPOSE: The aim of this study was to develop and assess the psychometric characteristics of a new brief self-report measure, which evaluates self-concealment behavior in the context of couples coping with chronic illness. METHODS: The Couples Illness Self-Concealment (CISC) scale was developed, emphasizing the active process involved in self-concealment. It was then tested among 56 cancer patients and partners of cancer patients. Correlations and multiple regression analysis were used to assess the internal consistency reliability and validity of the scale. RESULTS: Psychometric evaluation of the CISC final version, which includes 13 items, provides evidence that the scale has high internal consistency reliability. The findings support the construct validity of the scale, examined by both convergent validity and between group differences (patients vs. spouses). CONCLUSIONS: The CISC scale has acceptable psychometric qualities, internal consistency reliability and validity. The use of CISC may assist in revealing important aspects of couple's illness communication patterns, and enable examination of possible links between self-concealment behavior in the context of illness, and psychological outcome. It may also contribute to the assessment of interventions aimed at enhancing communication between partners coping with chronic illness.
