    ABSTRACT: The objective of this study was to compare survival in patients with stage IIIA (N2) non-small-cell lung cancer (NSCLC) treated with definitive chemoradiation (CRT) or surgery plus neoadjuvant chemoradiation or chemotherapy (CRTS). A retrospective analysis of 242 patients with stage IIIA (N2) NSCLC treated with curative intent between 1997 and 2007, identified 215 patients with surgically resectable disease. Overall survival outcomes were analysed using the Kaplan-Meier plots, log-rank tests and Cox proportional hazards models adjusting for age, gender, histology, smoking history and performance status. Recurrences were compared using competing risks methods, including the proportional subdistribution hazards regression model. CRTS was used to treat 104 patients and CRT in 111. Comparing CRTS with CRT patients, median age was 60 vs 62, 50 (48%) vs 69 (62%) were male and 65 (62.5%) vs 60 (54%) had adenocarcinoma. Of CRTS patients, 83 (80%) had a lobectomy. CRTS patients compared with CRT patients had decreased risk of recurrence at any site [hazard ratio (HR) = 0. 46, 95% confidence interval (CI): 0.32-0.64 P < 0.0001], local recurrence (HR = 0.50, 95% CI: 0.29-0.87, P = 0.013), loco--regional recurrence (HR = 0.51, 95% CI: 0.33-0.78, P = 0.002) and death (HR: 0.45, 95% CI: 0.33-0.62, P < 0.0001) with a median survival of 4.2 years vs 1.7 years). Risk of distant recurrence was also reduced in the surgical group (HR: 0.57; 95% CI: 0.38-0.87, P = 0.017). Treatment-related mortality was low in both cohorts. For patients with surgically resectable stage IIIA (N2) NSCLC, neoadjuvant therapy plus surgery reduces loco-regional and distant recurrence and improves survival. Treatment-related mortality was not significantly increased compared with the patients treated with CRT alone. © The Author 2015.

    ABSTRACT: The Brief Family History Questionnaire (bFHQ) was developed to identify endometrial cancer patients whose family histories suggest Lynch syndrome (LS). We compared the bFHQ, Extended Family History Questionnaire (eFHQ) and dictated medical records (DMR) to determine which family history screening strategy is superior in identifying LS in unselected women with newly diagnosed endometrial cancer that have undergone universal germline testing. Prospective cohort study recruiting women with newly diagnosed endometrial cancer to evaluate screening strategies to identify LS. Participants completed bFHQ and eFHQ, had tumor assessed with immunohistochemistry (IHC) for mismatch repair proteins (MMR) and micro-satellite instability testing and underwent universal germline testing for LS. The sensitivity, specificity, positive and negative predictive values (PPV, NPV) were compared between the family history screening strategies as well as IHC. 118 of 182 eligible patients (65%) consented; 87 patients (74%) were evaluable with both family history and germline mutation status. Median age was 61years (range 26 - 91). All 7 patients with confirmed LS were correctly identified by bFHQ, compared to 5 and 4 by eFHQ and DMR, respectively. The sensitivity, specificity, PPV and NPV values of bFHQ were 100%, 76.5%, 25.9% and 100%, respectively, performing similar to IHC testing. While eFHQ was more specific than bFHQ (86.7% vs. 76.5%, p=0.007), 2 cases of LS were missed. The patient-administered bFHQ effectively identified women with confirmed LS and is a good screening tool to triage women with endometrial cancer for further genetic assessment. Copyright © 2014.

    ABSTRACT: Immunohistochemistry (IHC) for mismatch repair protein expression, microsatellite instability (MSI) testing, tumor morphology, and family history were compared to determine which screening strategy is superior in identifying Lynch syndrome (LS) in unselected women with newly diagnosed endometrial cancer (EC) who have undergone universal germline mutation testing. A prospective cohort study was performed that recruited women with newly diagnosed EC. Participants completed a family history assessment with molecular characterization of EC with IHC and MSI testing and EC assessment for LS-associated morphologic features and underwent universal germline mutation testing for mutations in the mismatch repair pathway. The sensitivity, specificity, and positive and negative predictive values were compared between the screening strategies. A total of 118 (65%) of 182 consecutive women with EC participated. Of these, 34 women (29%) had tumors that were IHC deficient and 27 women (23%; N = 117) had tumors that were positive for MSI. Twenty women (17%) met IHC criteria and 16 women (15.2%, N = 105) met family history criteria based on Ontario Ministry of Health Criteria for the genetic assessment for LS. Seven women (5.9%) had a germline mutation: 4 had MLH1 (mutL homolog 1), 2 had MSH6 (mutS homolog 6), and 1 had MSH2 (mutS homolog 2). IHC in women aged <60 years had the best performance characteristics, with a sensitivity of 100%, a specificity of 86.1%, a positive predictive value of 58.3%, and a negative predictive value of 100%. Family history and tumor morphology both had the lowest sensitivity at 71.4%. Overall tumor morphology had the poorest performance, with a specificity of 42.1%. The mutation rate of 5.9% was higher than expected in this unselected cohort of women with EC. The superior screening strategy to identify women presenting with EC is universal IHC screening in women aged <60 years. Cancer 2014;;120:3932–3939.

    ABSTRACT: Background: Optimal treatment of glioblastoma (GBM) in the elderly remains unclear. The impact of age on treatment planning, toxicity, and efficacy at a Canadian Cancer Centre was retrospectively reviewed.Methods: Glioblastoma patients treated consecutively between 2004 and 2008 were reviewed. Utilizing 70 years as the threshold for definition of an elderly patient, treatments and outcome were compared in younger and elderly populations.Results: Four hundred and twenty one patients were included in this analysis and median overall survival (OS) for the entire cohort was 9.8 months. 290 patients were aged <70 (median age 57, range 17–69) and 131 were aged ≥70 (median age 76, range 70–93). Patients ≥70 were more likely to receive best supportive care (BSC) and all patients >70 who were treated with radiotherapy received <60 Gy (P<0.001), except one. Patients aged >70 demonstrated inferior survival (one year OS 16% versus 54% for those <70, HR 3.46, P<0.001). In patients treated with BSC only, age had no impact on survival (median survival two months in both groups, HR 0.89, P=0.75). For those treated with higher doses of radiotherapy (>30 Gy to <60 Gy), one year survival was 19% versus 24% in patients aged >70 versus <70 (HR 1.47, P=0.02) respectively.Conclusions: In this retrospective single institution series, elderly patients were more likely to be treated with BSC or palliative doses of radiotherapy. Randomized phase III study results are required for guidance in treatment of this population of patients.

    ABSTRACT: Oral progestin is an alternative to hysterectomy for women with complex atypical hyperplasia (CAH) or grade one endometrial cancer (G1EC) who wish fertility preservation. We evaluated treatment efficacy and fertility outcomes in this population. Women <45y treated with oral progestin for CAH or G1EC were identified from two cancer centres. Data were obtained from medical records and telephone questionnaires. Time until complete response (CR), and from CR until recurrence were censored for patients without events and analyzed for associations with patient and treatment characteristics; cumulative incidence functions were used to estimate event probability over time. 44 patients were identified, 19 (43%) with CAH and 25 (57%) with G1EC. Median age was 36.5y (26-44). 24 (55%) achieved CR (median time: 5.7months). Older age was associated with a lower likelihood of CR (HR 0.84, P=0.0003, 95% CI, 0.8-0.9). CR probability appeared to plateau after 12months of therapy. Among those with CR, 13 (54%) recurred (median time 3.5y). 24 patients (55%) underwent hysterectomy; 3 (13%) were upstaged. 11 (25%) underwent fertility treatment with the following outcomes: 6 (55%) no pregnancy, 2 (18%) at least one live infant, and 3 (27%) spontaneous abortion. One achieved a live birth without intervention. Oral progestin is an effective temporizing fertility-sparing treatment for women with CAH/G1EC. Fertility specialist involvement is recommended due to the low live birth rate without intervention. Progestin therapy should be re-evaluated at 1year in non-responders due to a low probability of success. Hysterectomy is recommended after childbearing due to a high recurrence rate.

    ABSTRACT: PURPOSETo describe outcomes of prospective trials of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC).Patients And methodsTwo trials of SBRT for patients with active HCC unsuitable for standard locoregional therapies were conducted from 2004 to 2010. All patients had Child-Turcotte-Pugh class A disease, with at least 700 mL of non-HCC liver. The SBRT dose range was 24 to 54 Gy in six fractions. Primary end points were toxicity and local control at 1 year (LC1y), defined as no progressive disease (PD) of irradiated HCC by RECIST (Response Evaluation Criteria in Solid Tumors). RESULTS: n = 50; Trial 2, 2007 to 2010: n = 52). Underlying liver disease was hepatitis B in 38% of patients, hepatitis C in 38%, alcohol related in 25%, other in 14%, and none in 7%. Fifty-two percent received prior therapies (no prior sorafenib). TNM stage was III in 66%, and 61% had multiple lesions. Median gross tumor volume was 117.0 mL (range, 1.3 to 1,913.4 mL). Tumor vascular thrombosis (TVT) was present in 55%, and extrahepatic disease was present in 12%. LC1y was 87% (95% CI, 78% to 93%). SBRT dose (hazard ratio [HR] = 0.96; P = .02) and being in Trial 2 (HR = 0.38; P = .03) were associated with LC1y on univariate analysis. Toxicity ≥ grade 3 was seen in 30% of patients. In seven patients (two with TVT PD), death was possibly related to treatment (1.1 to 7.7 months after SBRT). Median overall survival was 17.0 months (95% CI, 10.4 to 21.3 months), for which only TVT (HR = 2.47; P = .01) and being in Trial 2 (HR = 0.49; P = .01) were significant on multivariate analysis. CONCLUSION These results provide strong rationale for studying SBRT for HCC in a randomized trial.

    ABSTRACT: BACKGROUND AND PURPOSE: To analyze systematic changes in tumor and normal tissue anatomy and dosimetry using serial MR imaging during pulsed dose rate brachytherapy (PDR BT) for cervical cancer. MATERIAL AND METHODS: Forty-three patients with cervical cancer underwent MR-guided PDR BT using an intrauterine applicator alone after external beam radiotherapy. MR imaging was repeated on days 2 and 3 of treatment and the day 1 plan was applied to the re-contoured volumes. RESULTS: The mean uterine volume and mean HR CTV increased during treatment. This resulted in a decrease in the mean HR CTV D90 relative to the day 1 planned dose. There was no change in the mean bladder volume during treatment but the mean rectal volume increased. This correlated with an increase in the mean rectal dose. There were four local recurrences. There was no apparent relationship between either the planned or the delivered HR CTV D90 and local recurrence. There was only one case of late bladder toxicity but nine patients developed late rectal toxicity. The cumulative rectal dose during treatment was a better predictor of late rectal toxicity than the planned dose. CONCLUSIONS: Significant changes in tumor and normal tissue anatomy and dosimetry can occur during PDR BT and should be tracked and corrected using serial imaging and plan adaptation, especially when the day 1 tumor or normal tissue doses are close to the planning constraints.

    ABSTRACT: s u m m a r y Objectives: To describe the natural course of distant metastases (DMs) following radiotherapy (RT) or chemoradiotherapy (CRT) in HPV(+) oropharyngeal carcinoma (OPC). Methods: OPC treated with RT/CRT from 1/1/2000 to 5/31/2010 were reviewed. The natural course of DM were compared between HPV(+) and HPV(À) cohorts. Results: Median follow-up was 3.9 years. The DM rate were similar (11% vs. 15% at 3-years, p = 0.25) between the HPV(+) (n = 457) vs. the HPV(À) (n = 167) cases. While almost all (24/25) HPV(À) DM occurred within 2-years following RT (1 was at 2.1 years), 7/54 (13%) of HPV(+) DM were detected beyond 3 years (up to 5.3 years). Disseminating to >2 organs occurred in 18 (33%) HPV(+) vs. none in HPV(À). Post-DM survival rates were 11% vs. 4% at 2-years (p = 0.02) for the HPV(+) vs. HPV(À) cases respectively. 5/6 HPV(+) with lung oligo-metastasis were still alive with stable disease beyond 2-years after salvage procedures for DM (chemotherapy: 3; surgical resection: 2; radiotherapy: 1). Conclusions: Although DM rates are similar, the natural course of HPV(+) DM differs from that of HPV(À) patients: it may occur after a longer interval, often with a ''disseminating'' phenotype, and a small num-ber may have prolonged survival after salvage for DM.

    ABSTRACT: DNA methylation plays an important role in carcinogenesis and is being recognized as a promising diagnostic and prognostic biomarker for a variety of malignancies including Prostate cancer (PCa). The human kallikrein-related peptidases (KLKs) have emerged as an important family of cancer biomarkers, with KLK3, encoding for Prostate Specific Antigen, being most recognized. However, few studies have examined the epigenetic regulation of KLKs and its implications to PCa. To assess the biological effect of DNA methylation on KLK6 and KLK10 expression, we treated PC3 and 22RV1 PCa cells with a demethylating drug, 5-aza-2'deoxycytidine, and observed increased expression of both KLKs, establishing that DNA methylation plays a role in regulating gene expression. Subsequently, we have quantified KLK6 and KLK10 DNA methylation levels in two independent cohorts of PCa patients operated by radical prostatectomy between 2007-2011 (Cohort I, n = 150) and 1998-2001 (Cohort II, n = 124). In Cohort I, DNA methylation levels of both KLKs were significantly higher in cancerous tissue vs. normal. Further, we evaluated the relationship between DNA methylation and clinicopathological parameters. KLK6 DNA methylation was significantly associated with pathological stage only in Cohort I while KLK10 DNA methylation was significantly associated with pathological stage in both cohorts. In Cohort II, low KLK10 DNA methylation was associated with biochemical recurrence in univariate and multivariate analyses. A similar trend for KLK6 DNA methylation was observed. The results suggest that KLK6 and KLK10 DNA methylation distinguishes organ confined from locally invasive PCa and may have prognostic value.

    ABSTRACT: There is evidence that treatment of gynecologic cancer (GC) negatively affects body image and sexuality. The Sexual Adjustment and Body Image Scale (SABIS-G) was developed to assess disturbances after diagnosis of GC. The objective of this study was to confirm the factor structure using a confirmatory factor analysis (CFA). Women with a history of GC completed the SABIS-G, a 9-item self-report measure. Ninety randomly selected participants were used for the exploratory factor analysis (EFA). CFA was performed on the remaining participants (n = 204) to confirm the factor structure developed in the EFA against a one-factor model. Test-retest reliability between baseline and follow-up scores was assessed using the intraclass correlation coefficient. A total of 614 eligible patients were approached to participate: 398 (65%) consented to the study and 294 (74%) completed the SABIS-G. The median age was 53 years (range, 27-80 years) and the primary site of disease was: 120 (41%) uterine, 85 (29%) ovary, 82 (28%) cervix, and 7 (2%) other. A 2-factor structure was favored in the EFA, and the CFA fit indices indicated an excellent fit for the 2-factor measurement model (standardized root-mean-square residual = 0.05, non-normed fit index = 0.97, comparative fit index = 0.98). Internal consistency reliability was high for the Body Image (0.88) and Sexual Adjustment (0.91) subscales, as was test-retest reliability (0.89). These results confirm the 2-factor structure of the SABIS-G and provide evidence that this is a valid and reliable instrument to measure changes in body image and sexuality in women after a diagnosis of GC.

    ABSTRACT: To analyze, through chart review, the efficacy of salvage radiation therapy (sRT) for relapsed or progressive Hodgkin lymphoma (HL) patients who failed autologous stem cell transplant (ASCT). Among 347 patients with recurrent/refractory HL who received ASCT from 1986-2006, 163 had post-ASCT progression or relapse. Of these, 56 received sRT and form the basis of this report. Median age at sRT was 30 years (range, 17-59 years). Disease was confined to lymph nodes in 27 patients, whereas 24 had both nodal and extranodal disease. Salvage radiation therapy alone was given in 34 patients (61%), and sRT plus chemotherapy was given in 22 (39%). Median interval from ASCT to sRT was 0.8 years (range, 0.1-5.6 years). The median dose was 35 Gy (range, 8-40.3 Gy). The sRT technique was extended-field in 14 patients (25%) and involved-field in 42 (75%). The median follow-up from sRT was 31.3 months (range, 0.2-205.5 months). Overall response rate was 84% (complete response: 36%; partial response: 48%). The median overall survival was 40.8 months (95% confidence interval, 34.2-56.3 months). The 5-year overall survival was 29% (95% confidence interval, 14%-44%). The 2-year progression-free survival (PFS) was 16%; the 2-year local PFS was 65%, whereas the 2-year systemic PFS was 17%. The 1-year PFS was higher in patients in whom all diseased sites were irradiated (49%) compared with those in whom only the symptomatic site was treated (22%, P=.07). Among 20 alive patients, 5 were disease free (at 6.4, 6.8, 7.4, 7.9, and 17.1 years). For patients with HL who fail ASCT, a selective use of RT provides a durable local control rate of 65% at 2 years and should be considered as part of the standard management plan for the palliation of incurable HL. Occasionally irradiation of truly localized disease can lead to long-term survival.

    ABSTRACT: To report outcome of HPV-related [HPV(+)] oropharyngeal cancer (OPC) managed predominantly by altered-fractionation radiotherapy-alone (RT-alone). OPCs treated with RT-alone (n = 207) or chemoradiotherapy (CRT) (n = 151) from 2001 to 2008 were included. Overall survival (OS), local (LC), regional (RC) and distant (DC) control were compared for HPV(+) vs. HPV-unrelated [HPV(-)], by RT-alone vs. CRT, and by smoking pack-years (≤ 10 vs. >10). Multivariate analysis identified predictors. HPV(+) (n = 277) had better OS (81% vs. 44%), LC (93% vs. 76%), RC (94% vs. 79%) (all p < 0.01) but similar DC (89% vs. 86%, p = 0.87) vs. HPV(-) (n = 81). HPV(+) stage IV CRT (n = 125) had better OS (89% vs. 70%, p < 0.01), but similar LC (93% vs. 90%, p = 0.41), RC (94% vs. 90%, p = 0.31) and DC (90% vs. 83%, p = 0.22) vs. RT-alone (n = 96). Both HPV(+) RT-alone (n = 37) and CRT (n = 67) stage IV minimal smokers had favorable OS (86% vs. 88%, p = 0.45), LC (95% vs. 92%, p = 0.52), RC (97% vs. 93%, p = 0.22), and DC (92% vs. 86%, p = 0.37). RT-alone and heavy-smoking were independent predictors for lower OS but not CSS in multivariate analysis. Overall, HPV(+) RT-alone stage IV demonstrated lower survival but comparable disease control vs. CRT, but no difference was apparent among minimal smokers.

    ABSTRACT: The management of patients with relapsed or refractory Hodgkin's lymphoma who achieve less than a partial response to first-line salvage chemotherapy is unclear. The objective of this study was to evaluate response and outcomes to second-line salvage and autologous stem cell transplantation in patients not achieving a complete or partial response to platinum-containing first-line salvage chemotherapy. Consecutively referred transplant-eligible patients with relapsed/refractory Hodgkin's lymphoma after primary chemotherapy received gemcitabine, dexamethasone, and cisplatin as first salvage chemotherapy. Those achieving a complete or partial response, and those with a negative gallium scan and stable disease with bulk <5 cm proceeded to high-dose chemotherapy and autologous stem cell transplantation. Patients with progressive disease or stable disease with a positive gallium scan or bulk ≥ 5 cm were given second salvage chemotherapy with mini-BEAM (carmustine, etoposide, cytarabine, melphalan). Patients who responded (according to the same definition) proceeded to autologous stem cell transplantation. One hundred and thirty-one patients with relapsed/refractory Hodgkin's lymphoma received first-line salvage gemcitabine, dexamethasone, and cisplatin; of these patients 99 had at least a partial response (overall response rate 76%). One hundred and twelve (85.5%) patients proceeded to autologous stem cell transplantation, while the remaining 19 (14.5%) patients received mini-BEAM. Among these 19 patients, six had at least a partial response (overall response rate 32%), and nine proceeded to autologous stem cell transplantation. The remaining ten patients received palliative care. Seven of the nine patients transplanted after mini-BEAM had a subsequent relapse. Patients receiving second salvage mini-BEAM had poor outcomes, with a 5-year progression-free survival rate of 11% and a 5-year overall survival rate of 20%. Patients who require a second salvage regimen to achieve disease control prior to autologous stem cell transplantation have a relatively poor outcome and should be considered for alternative treatment strategies.

    ABSTRACT: In preparation for the launch of a gynecologic oncology survivorship program, this study looked at the informational needs of women with gynecologic cancers. Although studies have touched on some of these needs, no published literature has investigated the comprehensive informational needs of gynecologic oncology patients within all sites of gynecologic cancers. A needs assessment, consisting of a self-administered questionnaire, was conducted at an ambulatory gynecologic oncology clinic from August 2010 to March 2011. This study investigated the informational needs of patients, including the importance of information, the amount desired, and the preferred mode of delivery. Informational needs were grouped into six domains: medical, practical, physical, emotional, social, and spiritual. 185 surveys were analyzed and the majority of the respondents were Caucasian (77%) and over the age of 50 (66%). Forty-nine percent of respondents were diagnosed with ovarian cancer, and there was an even distribution between newly diagnosed patients (38%), those in long-term follow-up (27%), and those with recurrent disease (37%). Overall, respondents placed more importance on receiving medical information (P<0.01). The three preferred education modalities were; pamphlets, one-on-one discussions with health care professionals and websites. Age, education, and disease site were associated with differing informational needs. This study has highlighted the most important informational needs of patients with gynecologic malignancies in our patient population. This information may guide the development of clinical survivorship programs and educational resources for patients in the future.
