    Lung cancer is the leading cause of cancer death in developed countries. However, in the last few years we observed an important acceleration in drug development due to oncogenic driver tumors discovery. Sharing and putting together preclinical data from benchmark and data from clinical research is the scientific paradigm that allows real breakthrough in clinical practice in this field, but only a few targeted agents are worthy and practice changing. The clinical research and proper use of statistical methodology are the pillars to continue to achieve important goals like improvement of overall survival. A good medical oncologist should be able to critically read a scientific paper and move from the observed outcomes into clinical perspective. Despite clinical improvements, sometimes the union of promising targeted agents and optimistic expectations misrepresent the reality and the value of clinical research. In this article, we try to analyze the meaning of statistical assumptions from clinical trials, especially in lung cancer, through a critical review of the concept of value-based medicine. We also attempt to give the reader some practical tools to weigh scientific value of literature reports. PMID:26716052

    Background Colorectal cancer (CRC) is a major cause of worldwide morbidity and mortality. Surgical treatment is common, and there is a great need to improve the delivery of such care. The gold standard for evaluating surgery is within well-designed randomized controlled trials (RCTs); however, the impact of RCTs is diminished by a lack of coordinated outcome measurement and reporting. A solution to these issues is to develop an agreed standard “core” set of outcomes to be measured in all trials to facilitate cross-study comparisons, meta-analysis, and minimize outcome reporting bias. This study defines a core outcome set for CRC surgery. Methods and Findings The scope of this COS includes clinical effectiveness trials of surgical interventions for colorectal cancer. Excluded were nonsurgical oncological interventions. Potential outcomes of importance to patients and professionals were identified through systematic literature reviews and patient interviews. All outcomes were transcribed verbatim and categorized into domains by two independent researchers. This informed a questionnaire survey that asked stakeholders (patients and professionals) from United Kingdom CRC centers to rate the importance of each domain. Respondents were resurveyed following group feedback (Delphi methods). Outcomes rated as less important were discarded after each survey round according to predefined criteria, and remaining outcomes were considered at three consensus meetings; two involving international professionals and a separate one with patients. A modified nominal group technique was used to gain the final consensus. Data sources identified 1,216 outcomes of CRC surgery that informed a 91 domain questionnaire. First round questionnaires were returned from 63 out of 81 (78%) centers, including 90 professionals, and 97 out of 267 (35%) patients. Second round response rates were high for all stakeholders (>80%). Analysis of responses lead to 45 and 23 outcome domains being retained

    To analyze the importance of pre-treatment factors (age, sex, T, N, histological differentiation, site, Hb level, performance status) and to investigate the influence of cigarette smoking and pulmonary and cardiac diseases on treatment outcomes in laryngeal cancer patients. From the year 1989 until May 1995 372 consecutive patients with cancer of the larynx were radically irradiated at the 2nd Teleradiotherapy Department of the Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology in Warsaw (MSCMCC). Pt. characteristics - 88% men, 12% women, age: 29-82 years, stages: T1-20%, T2 -34%, T3 -30%, T4 -16%, lymph node metastases: 27%. Complete response to treatment (CR) - 71% of cases. Loco-regional control after 2 years 52% (T1-T2 - 64%, T3 - T4 - 40%). Early reactions: pain on swallowing, confluent mucositis and moist skin reaction in 69%, 48% and 41 % of cases, respectively. Serious late complications - 19 patients. In a majority of these cases several forms of serious damage were observed. Patients with advanced disease (T3-T4) present a two times higher death risk as compared to patients in earlier stages of the disease (T1-T2). Patients with cervical node metastases also present a two times higher death risk as compared to N0 cases. Patients with performance status 1 or more had a respectively three or four times higher death risk than patients with performance status - 0. No significant influence of sex, histological differentiation, site, hemoglobin level and cigarette smoking, pulmonary and coronary diseases on treatment outcome has been found. The survival curves come down steeply three and more years after treatment completion due to causes other than local failure. The limited number of serious early and late reactions suggests the possibility of a total dose increase. (author)

    The public is encouraged to participate in cancer education programs because it is believed that acquiring health-promoting knowledge will motivate participants to make the recommended, evidence-based behavioral modifications that should lead to reductions in cancer morbidity and mortality. Because of the extended time that elapses between conducting a health education program and the amassing of the scientific evidence needed to establish that an education program has ultimately resulted in a reduction in morbidity and mortality, researchers have sought more proximal and intermediate outcome measures as substitutes for the more distal desired outcomes. This paper presents an analysis of research published in the Journal of Cancer Education from 2000 through 2010, in which the impact of cancer education interventions was evaluated. The focus was to identify the proximal, intermediate, and distal outcome measures used to evaluate the impact of cancer education interventions. The results showed that researchers primarily focus on measuring the varied proximal outcomes (e.g., knowledge and attitude changes) of cancer education interventions. Intermediate outcome measures (the desired behavior change itself) received less attention, while distal outcomes (changes in morbidity and mortality) were never measured. This review gives cancer education researchers a review of the proximal and intermediate outcome measures and strategies that behavioral scientists recently used to overcome the challenges of measuring distal outcomes. Future reviews could expand this analysis to studies published in other journals and health disciplines. PMID:24189833

    Early melanoma and non-melanoma skin cancer of the facial area are primarily treated with surgery. Little is known about the outcomes of treatment for facial skin cancer patients. The objective of the study was to identify concerns about aesthetics, procedures and health from the patients' perspective after facial skin surgery. Semi-structured in-depth interviews were conducted with 15 participants. Line-by-line coding was used to establish categories and develop themes. We identified five major themes on the impact of skin cancer surgery: appearance-related concerns; psychological (e.g., fear of new cancers or recurrence); social (e.g. impact on social activities and interaction); physical (e.g. pain and swelling) concerns and satisfaction with the experience of care (e.g., satisfaction with surgeon). The priority of participants was the removal of the facial skin cancer, as this reduced their overall worry. The aesthetic outcome was secondary but important, as it had important implications on the participants' social and psychological functioning. The participants' experience with the care provided by the surgeon and staff also contributed to their satisfaction with their treatment. This conceptual framework provides the basis for the development of a new patient-reported outcome instrument. PMID:25833383

    Survival for childhood cancer has increased dramatically over the last 40 years with 5-year survival rates now approaching 80%. For many diagnostic groups, rapid increases in survival began in the 1970s with the broader introduction of multimodality approaches, often including combination chemotherapy with or without radiation therapy. With this increase in rates of survivorship has come the recognition that survivors are at risk for adverse health and quality-of-life outcomes, with risk being influenced by host-, disease-, and treatment-related factors. In 1994, the US National Cancer Institute funded the Childhood Cancer Survivor Study, a multi-institutional research initiative designed to establish a large and extensively characterized cohort of more than 14,000 5-year survivors of childhood and adolescent cancer diagnosed between 1970 and 1986. This ongoing study, which reflects the single most comprehensive body of information ever assembled on childhood and adolescent cancer survivors, provides a dynamic framework and resource to investigate current and future questions about childhood cancer survivors.

    Full Text Available Abstract Background Young women presenting with breast cancer are more likely to have a genetic predisposition to the disease than breast cancer patients in general. A genetic predisposition is known to increase the risk of new primary breast (and other cancers. It is unclear from the literature whether genetic status should be taken into consideration when planning adjuvant treatment in a young woman presenting with a first primary breast cancer. The primary aim of the POSH study is to establish whether genetic status influences the prognosis of primary breast cancer independently of known prognostic factors. Methods/design The study is a prospective cohort study recruiting 3,000 women aged 40 years or younger at breast cancer diagnosis; the recruiting period covers 1st June 2001 to 31st December 2007. Written informed consent is obtained at study entry. Family history and known epidemiological risk data are collected by questionnaire. Clinical information about diagnosis, treatment and clinical course is collected and blood is stored. Follow up data are collected annually after the first year. An additional recruitment category includes women aged 41 to 50 years who are found to be BRCA1 or BRCA2 gene carriers and were diagnosed with their first breast cancer during the study recruiting period. Discussion Power estimates were based on 10% of the cohort carrying a BRCA1 gene mutation. Preliminary BRCA1 and BRCA2 mutation analysis in a pilot set of study participants confirms we should have 97% power to detect a difference of 10% in event rates between gene carriers and sporadic young onset cases. Most of the recruited patients (>80% receive an anthracycline containing adjuvant chemotherapy regimen making planned analyses more straightforward.

    Summary Background Data: The epidemiology of venous thromboembolism (VTE) after cancer surgery is based on clinical trials on VTE prophylaxis that used venography to screen deep vein thrombosis (DVT). However, the clinical relevance of asymptomatic venography-detected DVT is unclear, and the population of these clinical trials is not necessarily representative of the overall cancer surgery population. Objective: The aim of this study was to evaluate the incidence of clinically overt VTE in a wide spectrum of consecutive patients undergoing surgery for cancer and to identify risk factors for VTE. Methods: @RISTOS was a prospective observational study in patients undergoing general, urologic, or gynecologic surgery. Patients were assessed for clinically overt VTE occurring up to 30 ± 5 days after surgery or more if the hospital stay was longer than 35 days. All outcome events were evaluated by an independent Adjudication Committee. Results: A total of 2373 patients were included in the study: 1238 (52%) undergoing general, 685 (29%) urologic, and 450 (19%) gynecologic surgery. In-hospital prophylaxis was given in 81.6% and postdischarge prophylaxis in 30.7% of the patients. Fifty patients (2.1%) were adjudicated as affected by clinically overt VTE (DVT, 0.42%; nonfatal pulmonary embolism, 0.88%; death 0.80%). The incidence of VTE was 2.83% in general surgery, 2.0% in gynecologic surgery, and 0.87% in urologic surgery. Forty percent of the events occurred later than 21 days from surgery. The overall death rate was 1.72%; in 46.3% of the cases, death was caused by VTE. In a multivariable analysis, 5 risk factors were identified: age above 60 years (2.63, 95% confidence interval, 1.21–5.71), previous VTE (5.98, 2.13–16.80), advanced cancer (2.68, 1.37–5.24), anesthesia lasting more than 2 hours (4.50, 1.06–19.04), and bed rest longer than 3 days (4.37, 2.45–7.78). Conclusions: VTE remains a common complication of cancer surgery, with a remarkable proportion

    Background: Oral cavity cancer is the most common cancer among rural India. There is a paucity of data for outcomes of operable oral cavity cancer from rural India. Use of maintenance metronomic may delay or avoid relapse. Aim: To evaluate outcomes of operable oral cavity carcinoma and evaluate impact of maintenance metronomic chemotherapy. Objectives: To evaluate disease-free survival (DFS), overall survival (OS), and factors affecting the outcome in operable oral cavity cancer. Materials and Methods: Data of patients diagnosed with oral cavity cancer registered between May 2008 and May 2014 were retrieved. Only those patients with operable oral cavity cancer and upfront definitive surgery were included in the study. Demographic profile, stage, tobacco consumption, adjuvant therapy, and pattern of failure were collected. Kaplan–Meir survival analysis was used to determine DFS and OS. Log-rank test was used to evaluate factors affecting outcome. Results: Median follow-up is 24 months. Out of 335 patients, 225 (67%) had advanced operable cancer with 42/225 (18%) and 183/225 (82%) as Stages III and IVA, respectively. Buccal mucosa was the most common subsite (178/335, 53%) followed by tongue (63/335, 19%). Ninety-two percent patients were addicted to smokeless tobacco, whereas 27% were smokers. Median DFS is 13 months with 2 years relative DFS 32%. Median OS is 30 months, with 2 years OS of 54%. Metronomic adjuvant oral chemotherapy was given in 130/225 (58%); Stage III and IVA patients with median of 14 months (3–18 months). Use of metronomic chemotherapy improved DFS (8 vs. 14 months, P = 0.22) and OS (14 vs. 26 months, P = 0.04). Conclusion: Oral cavity cancer is a major health care problem in rural India. Presentation at advanced stage leads to suboptimal outcomes. Benefit of metronomic maintenance chemotherapy in locally advanced oral cavity needs to be further evaluated prospectively.

  15. Outcome and patterns of failure in testicular lymphoma: a multicenter rare cancer network study

    International Nuclear Information System (INIS)

    Purpose: To assess the outcome and patterns of failure in patients with testicular lymphoma treated by chemotherapy (CT) and/or radiation therapy (RT). Methods and Materials: Data from a series of 36 adult patients with Ann Arbor Stage I (n=21), II (n=9), III (n=3), or IV (n=3) primary testicular lymphoma, consecutively treated between 1980 and 1999, were collected in a retrospective multicenter study by the Rare Cancer Network. Median age was 64 years (range: 21-91 years). Full staging workup (chest X-ray, testicular ultrasound, abdominal ultrasound, and/or thoracoabdominal computer tomography, bone marrow assessment, full blood count, lactate dehydrogenase, and cerebrospinal fluid evaluation) was completed in 18 (50%) patients. All but one patient underwent orchidectomy, and spermatic cord infiltration was found in 9 patients. Most patients (n=29) had CT, consisting in most cases of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) with (n=17) or without intrathecal CT. External RT was delivered to scrotum alone (n=12) or testicular, iliac, and para-aortic regions (n=8). The median RT dose was 31 Gy (range: 20-44 Gy) in a median of 17 fractions (10-24), using a median of 1.8 Gy (range: 1.5-2.5 Gy) per fraction. The median follow-up period was 42 months (range: 6-138 months). Results: After a median period of 11 months (range: 1-76 months), 14 patients presented lymphoma progression, mostly in the central nervous system (CNS) (n=8). Among the 17 patients who received intrathecal CT, 4 had a CNS relapse (p=NS). No testicular, iliac, or para-aortic relapse was observed in patients receiving RT to these regions. The 5-year overall, lymphoma-specific, and disease-free survival was 47%, 66%, and 43%, respectively. In univariate analyses, statistically significant factors favorably influencing the outcome were early-stage and combined modality treatment. Neither RT technique nor total dose influenced the outcome. Multivariate analysis revealed that the

    Full Text Available Abstract Background With the growing number of public repositories for high-throughput genomic data, it is of great interest to combine the results produced by independent research groups. Such a combination allows the identification of common genomic factors across multiple cancer types and provides new insights into the disease process. In the framework of the proportional hazards model, classical procedures, which consist of ranking genes according to the estimated hazard ratio or the p-value obtained from a test statistic of no association between survival and gene expression level, are not suitable for gene selection across multiple genomic datasets with different sample sizes. We propose a novel index for identifying genes with a common effect across heterogeneous genomic studies designed to remain stable whatever the sample size and which has a straightforward interpretation in terms of the percentage of separability between patients according to their survival times and gene expression measurements. Results The simulations results show that the proposed index is not substantially affected by the sample size of the study and the censoring. They also show that its separability performance is higher than indices of predictive accuracy relying on the likelihood function. A simulated example illustrates the good operating characteristics of our index. In addition, we demonstrate that it is linked to the score statistic and possesses a biologically relevant interpretation. The practical use of the index is illustrated for identifying genes with common effects across eight independent genomic cancer studies of different sample sizes. The meta-selection allows the identification of four genes (ESPL1, KIF4A, HJURP, LRIG1 that are biologically relevant to the carcinogenesis process and have a prognostic impact on survival outcome across various solid tumors. Conclusion The proposed index is a promising tool for identifying factors having a

  18. Outcome and Prognostic Factors in Endometrial Stromal Tumors: A Rare Cancer Network Study

    International Nuclear Information System (INIS)

    Purpose: To provide further understanding regarding outcome and prognostic factors of endometrial stromal tumors (EST). Methods and Materials: A retrospective analysis was performed on the records of 59 women diagnosed with EST and treated with curative intent between 1983 and 2007 in the framework of the Rare Cancer Network. Results: Endometrial stromal sarcomas (ESS) were found in 44% and undifferentiated ESS (UES) in 49% of the cases. In 7% the grading was unclear. Of the total number of patients, 33 had Stage I, 4 Stage II, 20 Stage III, and 1 presented with Stage IVB disease. Adjuvant chemotherapy was administered to 12 patients, all with UES. External-beam radiotherapy (RT) was administered postoperatively to 48 women. The median follow-up was 41.4 months. The 5-year overall survival (OS) rate was 96.2% and 64.8% for ESS and UES, respectively, with a corresponding 5-year disease-free survival (DFS) rate of 49.4% and 43.4%, respectively. On multivariate analysis, adjuvant RT was an independent prognostic factor for OS (p = 0.007) and DFS (p = 0.013). Locoregional control, DFS, and OS were significantly associated with age (≤60 vs. >60 years), grade (ESS vs. UES), and International Federation of Gynecology and Obstetrics stage (I–II vs. III–IV). Positive lymph node staging had an impact on OS (p < 0.001). Conclusion: The prognosis of ESS differed from that of UES. Endometrial stromal sarcomas had an excellent 5-year OS, whereas the OS in UES was rather low. However, half of ESS patients had a relapse. For this reason, adjuvant treatment such as RT should be considered even in low-grade tumors. Multicenter randomized studies are still warranted to establish clear guidelines.

    Despite availability of guidelines for lung cancer care, variations in lung cancer care among the elderly exist across the nation and are a cause for concern in rural and medically underserved areas. Therefore, the purpose of this study was to evaluate the patterns of lung cancer care and associated health outcomes among elderly residing in a rural and medically underserved area. The authors identified 1924 elderly lung cancer patients from the West Virginia Cancer Registry-Medicare linked database (2002-2007) and categorized them by receipt of guideline-concordant (appropriate and timely) care using guidelines from the American College of Chest Physicians, British Thoracic Society, and the RAND Corporation. Hierarchical generalized logistic models were constructed to identify variables associated with receipt of guideline-concordant care. Kaplan-Meier analysis and log-rank test were used to compare 3-year survival outcomes. Multivariate Cox proportional hazards models were constructed to estimate lung cancer mortality risk associated with nonreceipt of guideline-concordant care. Although guideline-concordant appropriate care was received by fewer than half of all patients (46.5%), of those receiving care, 78.7% received it in a timely manner. Delays in diagnosis and treatment varied significantly. Survival outcomes significantly improved with appropriate care (799 vs. 366 days; P≤0.05), but did not improve with timely care. This study highlights the critical need to address disparities in receipt of guideline-concordant lung cancer care among the elderly residing in rural and medically underserved areas. Although lung cancer diagnostic and management services are covered under the Medicare program, underutilization of these services is a concern. (Population Health Management 2016;19:109-119).

  20. Quality of care indicators and their related outcomes: A population-based study in prostate cancer patients treated with radiotherapy

    International Nuclear Information System (INIS)

    Background and purpose: We describe variations across the regional cancer centres in Ontario, Canada for five prostate cancer radiotherapy (RT) quality indicators: incomplete pre-treatment assessment, follow-up care, leg immobilization, bladder filling, and portal film target localization. Along with cancer centre volume, we examined each indicator’s association with relevant outcomes: long-term cause-specific survival, urinary incontinence, and gastrointestinal and genitourinary late morbidities. Materials and methods: We conducted a population-based retrospective cohort study of 924 prostate cancer patients diagnosed between 1990 and 1998 who received RT within 9 months of diagnosis. Data sources included treating charts and registry and administrative data. The associations between indicators and outcomes were analysed using regression techniques to control for potential confounders. Results: Practice patterns varied across the regional cancer centres for all indicators (p < 0.0001). Incomplete pre-treatment assessment was associated with worse cause-specific survival although this result was not significant when adjusted for confounding (adjusted RR = 1.78, 95% CI = 0.79–3.98). Treatment without leg immobilization (adjusted RR = 1.72, 95% CI = 1.16–2.56) and with an empty bladder (adjusted RR = 1.98, 95% CI = 1.08–3.63) was associated with genitourinary late morbidities. Treatment without leg immobilization was also associated with urinary incontinence (adjusted RR = 2.18, 95% CI = 1.23–3.87). Conclusions: We documented wide variations in practice patterns. We demonstrated that measures of quality of care can be shown to be associated with clinically relevant outcomes in a population-based sample of prostate cancer patients

METHODS: The study comprised 3,580 patients who were treated with curative intent either by laparoscopic gastrectomy (2,041 patients or open gastrectomy (1,539 patents between January 2005 and October 2013. The surgical outcomes were compared between the two groups. RESULTS: Laparoscopic gastrectomy was associated with significantly less blood loss, transfused patient number, time to ground activities, and post-operative hospital stay, but with similar operation time, time to first flatus, and time to resumption of diet, compared with the open gastrectomy. No significant difference in the number of lymph nodes dissected was observed between these two groups. The morbidity and mortality rates of the LG group were comparable to those of the OG group (13.6% vs. 14.4%, P = 0.526, and 0.3% vs. 0.2%, P = 0.740. The 3-year disease-free and overall survival rates between the two groups were statistically significant (P<0.05. According to the UICC TNM classification of gastric cancer, the 3-year disease-free and overall survival rates were not statistically different at each stage. CONCLUSIONS: Our single-center study of a large patient series revealed that LG for gastric cancer yields comparable surgical outcomes. This result was also true of local advanced gastric cancer (AGC. A well-designed randomized controlled trial comparing surgical outcomes between LG and OG in a larger number of patients for AGC can be carried out.

The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery.Results: Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001, but the time to soft food intake (6.0 vs 6.6 days, P=0.036 and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018 were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001. The 5-year overall survival (90.8% vs 88.6%, P=0.540 and disease-free survival (86.1% vs 78.9%, P=0.201 rates were similar in both groups.Conclusion: The present study showed that laparoscopic surgery is associated

    International Nuclear Information System (INIS)

    Purpose To assess the clinical profile, treatment outcome, and prognostic factors in primary spinal epidural lymphoma (PSEL). Methods and Materials Between 1982 and 2002, 52 consecutive patients with PSEL were treated in nine institutions of the Rare Cancer Network. Forty-eight patients had an Ann Arbor stage IE and four had a stage IIE. Forty-eight patients underwent decompressive laminectomy, all received radiotherapy (RT) with (n = 32) or without chemotherapy (n = 20). Median RT dose was 36 Gy (range, 6-50 Gy). Results Six (11%) patients progressed locally and 22 (42%) had a systemic relapse. At last follow-up, 28 patients were alive and 24 had died. The 5-year overall survival, disease-free survival, and local control were 69%, 57%, and 88%, respectively. In univariate analyses, favorable prognostic factors were younger age and complete neurologic response. Multivariate analysis showed that combined modality treatment, RT volume, total dose more than 36 Gy, tumor resection, and complete neurologic response were favorable prognostic factors. Conclusions Primary spinal epidural lymphoma has distinct clinical features and outcome, with a relatively good prognosis. After therapy, local control is excellent and systemic relapse occurs in less than half the cases. Combined modality treatment appears to be superior to RT alone

Twenty-one underwent a mastectomy, 39 conservative surgery and 23 biopsy; 51 received radiotherapy (RT with (n = 37 or without (n = 14 chemotherapy. Median RT dose was 40 Gy (range 12–55 Gy. Results Ten (12% patients progressed locally and 43 (55% had a systemic relapse. Central nervous system (CNS was the site of relapse in 12 (14% cases. The 5-yr overall survival, lymphoma-specific survival, disease-free survival and local control rates were 53%, 59%, 41% and 87% respectively. In the univariate analyses, favorable prognostic factors were early stage, conservative surgery, RT administration and combined modality treatment. Multivariate analysis showed that early stage and the use of RT were favorable prognostic factors. Conclusion The outcome of PBL is fair. Local control is excellent with RT or combined modality treatment but systemic relapses, including that in the CNS, occurs frequently.

  6. Strategies and opportunities to STOP colon cancer in priority populations: pragmatic pilot study design and outcomes

    International Nuclear Information System (INIS)

    Colorectal-cancer is a leading cause of cancer death in the United States, and Latinos have particularly low rates of screening. Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC) is a partnership among two research institutions and a network of safety net clinics to promote colorectal cancer screening among populations served by these clinics. This paper reports on results of a pilot study conducted in a safety net organization that serves primarily Latinos. The study assessed two clinic-based approaches to raise rates of colorectal-cancer screening among selected age-eligible patients not up-to-date with colorectal-cancer screening guidelines. One clinic each was assigned to: (1) an automated data-driven Electronic Health Record (EHR)-embedded program for mailing Fecal Immunochemical Test (FIT) kits (Auto Intervention); or (2) a higher-intensity program consisting of a mailed FIT kit plus linguistically and culturally tailored interventions delivered at the clinic level (Auto Plus Intervention). A third clinic within the safety-net organization was selected to serve as a passive control (Usual Care). Two simple measurements of feasibility were: 1) ability to use real-time EHR data to identify patients eligible for each intervention step, and 2) ability to offer affordable testing and follow-up care for uninsured patients. The study was successful at both measurements of feasibility. A total of 112 patients in the Auto clinic and 101 in the Auto Plus clinic met study inclusion criteria and were mailed an introductory letter. Reach was high for the mailed component (92.5% of kits were successfully mailed), and moderate for the telephone component (53% of calls were successful completed). After exclusions for invalid address and other factors, 206 (109 in the Auto clinic and 97 in the Auto Plus clinic) were mailed a FIT kit. At 6 months, fecal test completion rates were higher in the Auto (39.3%) and Auto Plus (36.6%) clinics

    PURPOSEProlonged and disabling fatigue is prevalent after cancer treatment, but the early natural history of cancer-related fatigue (CRF) has not been systematically examined to document consistent presence of symptoms. Hence, relationships to cancer, surgery, and adjuvant therapy are unclear. PATIENTS AND METHODSA prospective cohort study of women receiving adjuvant treatment for early-stage breast cancer was conducted. Women (n = 218) were enrolled after surgery and observed at end treatment and at 1, 3, 6, 9, and 12 months as well as 5 years. Structured interviews and self-report questionnaires were used to record physical and psychologic health as well as disability and health care utilization. Patients with CRF persisting for 6 months were assessed to exclude alternative medical and psychiatric causes of fatigue. Predictors of persistent fatigue, mood disturbance, and health care utilization were sought by logistic regression.ResultsThe case rate for CRF was 24% (n = 51) postsurgery and 31% (n = 69) at end of treatment; it became persistent in 11% (n = 24) at 6 months and 6% (n = 12) at 12 months. At each time point, approximately one third of the patients had comorbid mood disturbance. Persistent CRF was predicted by tumor size but not demographic, psychologic, surgical, or hematologic parameters. CRF was associated with significant disability and health care utilization. CONCLUSIONCRF is common but generally runs a self-limiting course. Much of the previously reported high rates of persistent CRF may be attributable to factors unrelated to the cancer or its treatment.

    Background/Aims Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC) that has demonstrated a minimal risk of lymph node metastasis in retrospective studies. We sought to prospectively evaluate the short-term outcomes of ESD treatment in EGCs. Methods A prospective multicenter cohort study of neoplasms 3 cm or less in diameter at endoscopic size evaluation was performed in 12 Korean ESD study group-related university hospitals and the National Cancer Center. Resected specimens were evaluated by the central pathologic review board. Results A patient cohort (n=712) with a total of 737 EGCs was analyzed. The margin-freeen bloc resection rate was 97.3%, and curative resection of 640 lesions (86.8%) was achieved. Lower curative resection rates were associated with lesions 2 to 3 cm in size prior to ESD compared with lesions 2 cm or less in size (78.6% vs 88.1%, respectively, p=0.009). Significant factors associated with noncurative resection were moderately or poorly differentiated histological type, posterior wall tumor location, tumor size larger than 3 cm, ulceration, and submucosal invasion. Delayed bleeding occurred in 49 patients (6.9%), and 12 patients (1.7%) exhibited perforations. Conclusions ESD is an effective treatment with a high curative resection rate for EGCs that meets relatively conservative pre-ESD indications. Long-term survival outcomes should be evaluated in follow-up studies. PMID:27172929

    Full Text Available BACKGROUND: A beneficial effect of regional anesthesia on cancer related outcome in various solid tumors has been proposed. The data on prostate cancer is conflicting and reports on long-term cancer specific survival are lacking. METHODS: In a retrospective, single-center study, outcomes of 148 consecutive patients with locally advanced prostate cancer pT3/4 who underwent retropubic radical prostatectomy (RRP with general anesthesia combined with intra- and postoperative epidural analgesia (n=67 or with postoperative ketorolac-morphine analgesia (n=81 were reviewed. The median observation time was 14.00 years (range 10.87-17.75 yrs. Biochemical recurrence (BCR-free, local and distant recurrence-free, cancer-specific, and overall survival were estimated using the Kaplan-Meier technique. Multivariate Cox proportional-hazards regression models were used to analyze clinicopathologic variables associated with disease progression and death. RESULTS: The survival estimates for BCR-free, local and distant recurrence-free, cancer-specific survival and overall survival did not differ between the two groups (P=0.64, P=0.75, P=0.18, P=0.32 and P=0.07. For both groups, higher preoperative PSA (hazard ratio (HR 1.02, 95% confidence interval (CI 1.01-1.02, P<0.0001, increased specimen Gleason score (HR 1.24, 95% CI 1.06-1.46, P=0.007 and positive nodal status (HR 1.66, 95% CI 1.03-2.67, P=0.04 were associated with higher risk of BCR. Increased specimen Gleason score predicted death from prostate cancer (HR 2.46, 95% CI 1.65-3.68, P<0.0001. CONCLUSIONS: General anaesthesia combined with epidural analgesia did not reduce the risk of cancer progression or improve survival after RRP for prostate cancer in this group of patients at high risk for disease progression with a median observation time of 14.00 yrs.

  15. Factors influencing survival outcome for radiotherapy for biliary tract cancer: A multicenter retrospective study

    International Nuclear Information System (INIS)

    Purpose: To seek for the possible factors influencing overall survival (OS) with radiotherapy (RT) for biliary tract cancer. Materials and methods: Data were collected retrospectively from RT database of 31 institutions in Japan. All patients underwent at least external beam RT. The factors influencing OS were investigated. Results: Data of 498 patients were analyzed. Median OS of the 212 patients who underwent surgery was significantly better than that of the 286 patients without surgery (31 vs. 15 months, p < 0.001). The OS for the R0 or R1 resection group was significantly longer than that for the R2 or non-surgery group, as well as for n0 compared to n1 (all p < 0.001). Chemoradiotherapy (CRT), both sequential and concurrent, resulted in a better OS than RT alone for the n1 group (31 vs. 13 months, p < 0.001), and marginally better for the R0/R1 group (p = 0.065; p = 0.054 for concurrent CRT). However, no such benefit was observed for the R2/non-surgical patients. Multivariate analysis identified performance status, clinical stage, and surgery as significant factors. Conclusion: Surgery, especially R0/R1 resection, seemed as the gold standard for treatment of biliary tract cancer including RT, even in the highly heterogeneous population obtained from the multicenter retrospective study. The possibility was shown that CRT yielded better survival benefit especially for n1 patients. We recommend that future prospective trials include an arm of adjuvant CRT at least for n1 and possibly R0/R1 patients

    Full Text Available Abstract Background This retrospective study evaluated the impact of disease progression and of specific sites of metastasis on patient reported outcomes (PROs that assess symptom burden and health related quality of life (HRQoL in women with metastatic breast cancer (mBC. Methods HER-2 negative mBC patients (n = 102 were enrolled from 7 U.S. community oncology practices. Demographic, disease and treatment characteristics were abstracted from electronic medical records and linked to archived Patient Care Monitor (PCM assessments. The PCM is a self-report measure of symptom burden and HRQoL administered as part of routine care in participating practices. Linear mixed models were used to examine change in PCM scores over time. Results Mean age was 57 years, with 72% of patients Caucasian, and 25% African American. Median time from mBC diagnosis to first disease progression was 8.8 months. Metastasis to bone (60%, lung (28% and liver (26% predominated at initial metastatic diagnosis. Results showed that PCM items assessing fatigue, physical pain and trouble sleeping were sensitive to either general effects of disease progression or to effects associated with specific sites of metastasis. Progression of disease was also associated with modest but significant worsening of General Physical Symptoms, Treatment Side Effects, Acute Distress and Impaired Performance index scores. In addition, there were marked detrimental effects of liver metastasis on Treatment Side Effects, and of brain metastasis on Acute Distress. Conclusions Disease progression has a detrimental impact on cancer-related symptoms. Delaying disease progression may have a positive impact on patients' HRQoL.

    Prostate cancer outcomes research incorporates a broad spectrum of endpoints, from clinical or intermediate endpoints, such as tumor shrinkage or patient compliance, to final endpoints, such as survival or disease-free survival. Three types of nontraditional endpoints that are of growing interest-health-related quality of life (QOL), satisfaction with care, and economic cost impact-hold the promise of improving our ability to understand the full burden of prostate cancer screening and treatment. In this article we review the last decade's published literature regarding the health-related QOL, satisfaction, and economic outcomes of prostate cancer screening and treatment to determine the "state of the science" of outcomes measurement. The focus is the enumeration of the types of outcome measurement used in the studies not the determination of the results of the studies. Studies were identified by searching Medline (1990-2000). Articles were included if they presented original data on any patient-centered outcome (including costs or survival alone) for men screened and treated for prostate cancer. Review papers were excluded unless they were quantitative syntheses of the results of other primary studies. Economic and decision analytic papers were included if they presented information on outcomes of real or hypothetical patient cohorts. Each retrieved article was reviewed by one of the authors. Included papers were assigned one primary, mutually exclusive study design. For the "primary data" studies, information was abstracted on care setting, dates of the study, sample size, racial distribution, age, tumor differentiation, tumor stage, survival, statistical power, and types of outcomes measures (QOL-generic, QOL-cancer specific, QOL-prostate cancer specific, satisfaction, costs, utilities, and other). For the "economic and decision analytic" papers, information was abstracted on stage of disease, age range, outcomes, costs, and whether utilities were measured. Of

    Objective The aim of this study is to describe the clinical characteristics and outcome of cancer diagnosed during pregnancy. Methods This is a retrospective cohort study of women who were diagnosed with cancer during pregnancy at a tertiary academic hospital between 1995 and 2013. Maternal characteristics, gestational age at diagnosis, and type, stage, symptoms and signs of cancer for each patient were retrieved from the medical records. The cancer treatment, pregnancy management and the subsequent perinatal and maternal outcomes for each cancer were assessed. Results A total of 87 women were diagnosed with cancer during pregnancy (172.6 cases per 100,000 deliveries). The most common cancer was breast cancer (n=20), followed by gastrointestinal (n=17), hematologic (n=13), thyroid (n=11), central nervous system (n=7), cervical (n=7), ovarian (n=5), lung (n=3), and other cancers (n=4). Eighteen (20.7%) patients terminated their pregnancies. In the 69 (79.3%) patients who maintained their pregnancies, one patient miscarried and 34 patients delivered preterm. Of the preterm babies, 24 (70.6%) were admitted to the neonatal intensive care unit and 3 (8.8%) of those expired. The maternal mortality rate was 31.0%, with highest rate seen with lung cancers (66.7%), followed by gastrointestinal (50.0%), central nervous system (50.0%), hematologic (30.8%), breast (25.0%), ovarian (20.0%) cervical (14.3%), and thyroid cancers (0%). Conclusion The clinical characteristics and outcome of cancer during pregnancy were highly variable depending on the type of cancer. However, timely diagnosis and appropriate management of cancer during pregnancy may improve both maternal and neonatal outcome. PMID:26866029

    Laparoscopic resection for colon cancer has been proven to have a similar oncological efficacy compared to open resection. Despite this, it is performed by a minority of colorectal surgeons. The aim of our study was to evaluate the short-term clinical, oncological and survival outcomes in all patients undergoing laparoscopic resection for colon cancer.

  9. Outcome and prognostic factors in cerebellar glioblastoma multiforme in adults: A retrospective study from the Rare Cancer Network

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to assess the outcome in patients with cerebellar glioblastoma (GBM) treated in 15 institutions of the Rare Cancer Network. Methods and Materials: Data from a series of 45 adult patients with cerebellar GBM were collected in a retrospective multicenter study. Median age was 50.3 years. Brainstem invasion was observed in 9 (20%) patients. Radiotherapy (RT) was administered to 36 patients (with concomitant chemotherapy, 7 patients). Adjuvant chemotherapy after RT was administered in 8 patients. Median RT dose was 59.4 Gy. Median follow-up was 7.2 months (range, 3.4-39.0). Results: The 1-year and 2-year actuarial overall survival rate was 37.8% and 14.7%, respectively, and was significantly influenced by salvage treatment (p = 0.048), tumor volume (p = 0.044), extent of neurosurgical resection (p = 0.019), brainstem invasion (p = 0.0013), additional treatment after surgery (p < 0.001), and completion of the initial treatment (p < 0.001) on univariate analysis. All patients experienced local progression: 8 and 22 had progression with and without a distant failure, respectively. The 1- and 2-year actuarial progression free survival was 25% and 10.7%, respectively, and was significantly influenced by brainstem invasion (p = 0.002), additional treatment after surgery (p = 0.0016), and completion of the initial treatment (p < 0.001). On multivariate analysis, survival was negatively influenced by the extent of surgery (p = 0.03) and brainstem invasion (p = 0.02). Conclusions: In this multicenter retrospective study, the observed pattern of failure was local in all cases, but approximately 1 patient of 4 presented with an extracerebellar component. Brainstem invasion was observed in a substantial number of patients and was an adverse prognostic factor

  10. Beta-carotene Antioxidant Use During Radiation Therapy and Prostate Cancer Outcome in the Physicians' Health Study

    International Nuclear Information System (INIS)

    Purpose: The safety of antioxidant supplementation during radiation therapy (RT) for cancer is controversial. Antioxidants could potentially counteract the pro-oxidant effects of RT and compromise therapeutic efficacy. We performed a prospective study nested within the Physicians’ Health Study (PHS) randomized trial to determine if supplemental antioxidant use during RT for prostate cancer is associated with an increased risk of prostate cancer death or metastases. Methods and Materials: PHS participants (383) received RT for prostate cancer while randomized to receive beta-carotene (50 mg on alternate days) or placebo. The primary endpoint was time from RT to lethal prostate cancer, defined as prostate cancer death or bone metastases. The Kaplan-Meier method was used to estimate survival probabilities and the log-rank test to compare groups. Cox proportional hazards regression was used to estimate the effect of beta-carotene compared with that of placebo during RT. Results: With a median follow-up of 10.5 years, there was no significant difference between risk of lethal prostate cancer with the use of beta-carotene during RT compared with that of placebo (hazard ratio = 0.72; 95% confidence interval [CI], 0.42–1.24; p = 0.24). After we adjusted for age at RT, prostate-specific antigen serum level, Gleason score, and clinical stage, the difference remained nonsignificant. The 10-year freedom from lethal prostate cancer was 92% (95% CI, 87–95%) in the beta-carotene group and 89% (95% CI, 84–93%) in the placebo group. Conclusion: The use of supplemental antioxidant beta-carotene during RT was not associated with an increased risk of prostate cancer death or metastases. This study suggests a lack of harm from supplemental beta-carotene during RT for prostate cancer.

    Full Text Available Abstract Background The prediction of pathological outcomes prior to surgery remains a challenging problem for the appropriate surgical indication of prostate cancer. This study was performed to identify preoperative values predictive of pathological and oncological outcomes based on standardized extended prostate biopsies with core histological results diagrammed/mapped in patients receiving radical prostatectomy for prostate cancer clinically diagnosed as localized or locally advanced disease. Methods In 124 patients with clinically localized or locally advanced prostate cancer (cT1c–cT3a without prior treatment, pathological outcomes on the surgical specimen including seminal vesicle involvement (SVI, positive surgical margin (PSM, and perineural invasion (PNI were studied in comparison with clinical parameters based on the results of 14-core prostate biopsies comprising sextant, laterally-directed sextant, and bilateral transition zone (TZ sampling. Results Concerning the association of pathological outcomes with oncological outcomes, patients with PSM and PNI on surgical specimens had poorer biochemical-progression-free survival than those without PSM (logrank p = 0.002 and PNI (p = 0.003; it was also poorer concerning SVI, although the difference was not significant (p = 0.120.

    Background To investigate potential changes in perceptual, acoustic and patient-reported outcomes over 12 months for laryngeal cancer patients treated with radiotherapy. Material and methods A total of 40 patients with Tis-T3 laryngeal cancer treated with curative intent by radiotherapy were included in this prospective longitudinal descriptive study. Patients were followed pre-radiotherapy, one month, six months and 12 months post-radiotherapy, where voice recordings and patient-reported outcome instruments (European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core30, Head and Neck35, Swedish Self-Evaluation of Communication Experiences after Laryngeal Cancer) were completed at each appointment. Perceptual analysis, using the Grade-Roughness-Breathiness-Asthenia-Strain scale and vocal fry parameters, and acoustic measures including harmonics-to-noise ratio (HNR), jitter, shimmer and mean spoken fundamental frequency (MSFF) were produced from voice recordings. Results All patients presented with dysphonic voices pre-radiotherapy, where 95% demonstrated some degree of vocal roughness. This variable improved significantly immediately post-radiotherapy, however, then deteriorated again between six and 12 months. Vocal fry also increased significantly at 12 months. Acoustic measures were abnormal pre- and post-treatment with no significant change noted except for MSFF, which lowered significantly by 12 months. Health-related quality of life (HRQL) deteriorated post-radiotherapy but returned to pretreatment levels by 12 months. Conclusion By 12 months, most perceptual, acoustic, patient-reported voice and HRQL outcomes for laryngeal cancer patients treated by radiotherapy had showed no significant improvements compared to pretreatment function. Further studies are required to investigate potential benefits of voice rehabilitation following radiotherapy. PMID:27056401

    Full Text Available Abstract Background Laparoscopically-assisted right hemicolectomy (LRH is an acceptable alternative to open surgery for right-sided colon cancer which offers patients less pain and faster recovery. However, special equipment and substantial surgical experience are required. The aim of the study is to compare the short-term surgical outcomes of LRH and open right hemicolectomy through right transverse skin crease incision (ORHT for right-sided colon cancer. Patients and methods This retrospective study included 33 patients with right-sided colon cancer who underwent elective right hemicolectomy by laparoscopic or open approaches through right transverse skin crease incision between March 2004 and September 2006 at the Department of Surgery, Faculty of Medicine Siriraj Hospital. Operative details, postoperative requirement of narcotics, recovery of bowel function, and oncological parameters were analyzed. Results Thirteen patients underwent LRH and 20 patients underwent ORHT. Both approaches achieved adequate oncological resection of the tumor. The laparoscopic group were characterized by shorter average incision lengths (7.7 vs 10.3 cm; p Conclusion LRH and ORHT for right-sided colon cancer resulted in the same short-term surgical outcomes including postoperative bowel function, narcotics consumption and length of hospital stay. However, LRH required a significantly longer operating time.

    Full Text Available Abstract Background Emerging trends and new policies suggest that more cancer patients might die at home in the future. However, not all have equal chances of achieving this. Furthermore, there is lack of evidence to support that those who die at home experience better care and a better death than those who die as inpatients. The QUALYCARE study aims to examine variations in the quality and costs of end-of-life care, preferences and palliative outcomes associated with dying at home or in an institution for cancer patients. Methods/Design Mortality followback survey (with a nested case-control study of home vs. hospital deaths conducted with bereaved relatives of cancer patients in four Primary Care Trusts in London. Potential participants are identified from death registrations and approached by the Office for National Statistics in complete confidence. Data are collected via a postal questionnaire to identify the informal and formal care received in the three months before death and the associated costs, relatives' satisfaction with care, and palliative outcomes for the patients and their relatives. A well-established questionnaire to measure relatives' views on the care integrates four brief and robust tools - the Client Service Receipt Inventory, the Palliative Outcome Scale, the EQ-5 D and the Texas Revised Inventory of Grief. Further questions assess patients and relatives' preferences for place of death. The survey aims to include 500 bereaved relatives (140 who experienced a home death, 205 a hospital death, 115 a hospice death and 40 a nursing home death. Bivariate and multivariate analyses will explore differences in place of death and place of end-of-life care, in preferences for place of death, patients' palliative outcomes and relatives' bereavement outcomes, in relation to place of death. Factors influencing death at home and the costs of end-of-life care by place of death will be identified. Discussion Collecting data on end

    Full Text Available Abstract Background Little is known about the effects of professional staffing on cancer surgical outcomes. The present study aimed to investigate the association between cancer surgical outcomes and physician/nurse staffing in relation to hospital volume. Methods We analyzed 131,394 patients undergoing lung lobectomy, esophagectomy, gastrectomy, colorectal surgery, hepatectomy or pancreatectomy for cancer between July and December, 2007–2008, using the Japanese Diagnosis Procedure Combination database linked to the Survey of Medical Institutions data. Physician-to-bed ratio (PBR and nurse-to-bed ratio (NBR were determined for each hospital. Hospital volume was categorized into low, medium and high for each of six cancer surgeries. Failure to rescue (FTR was defined as a proportion of inhospital deaths among those with postoperative complications. Multi-level logistic regression analysis was performed to examine the association between physician/nurse staffing and FTR, adjusting for patient characteristics and hospital volume. Results Overall inhospital mortality was 1.8%, postoperative complication rate was 15.2%, and FTR rate was 11.9%. After adjustment for hospital volume, FTR rate in the group with high PBR (≥19.7 physicians per 100 beds and high NBR (≥77.0 nurses per 100 beds was significantly lower than that in the group with low PBR ( Conclusions Well-staffed hospitals confer a benefit for cancer surgical patients regarding reduced FTR, irrespective of hospital volume. These results suggest that consolidation of surgical centers linked with migration of medical professionals may improve the quality of cancer surgical management.

    Objectives:Later weekday of surgery for oesophageal cancer seems to increase 5-year mortality, but the mechanisms are unclear. We hypothesised that early postoperative reoperations and mortality might explain this association, since reoperation after oesophagectomy decreases long-term prognosis, and later weekday of elective surgery increases 30-day mortality.Design:This was a population-based cohort study during the study period 1987–2014.Setting:All Swedish hospitals conducting elective sur...

  3. A comparison of survival outcomes and side effects of toremifene or tamoxifen therapy in premenopausal estrogen and progesterone receptor positive breast cancer patients: a retrospective cohort study

    International Nuclear Information System (INIS)

    In premenopausal women, endocrine adjuvant therapy for breast cancer primarily consists of tamoxifen alone or with ovarian suppressive strategies. Toremifene is a chlorinated derivative of tamoxifen, but with a superior risk-benefit profile. In this retrospective study, we sought to establish the role of toremifene as an endocrine therapy for premenopausal patients with estrogen and/or progesterone receptor positive breast cancer besides tamoxifen. Patients with early invasive breast cancer were selected from the breast tumor registries at the Sun Yat-Sen Memorial Hospital (China). Premenopausal patients with endocrine responsive breast cancer who underwent standard therapy and adjuvant therapy with toremifene or tamoxifen were considered eligible. Patients with breast sarcoma, carcinosarcoma, concurrent contralateral primary breast cancer, or with distant metastases at diagnosis, or those who had not undergone surgery and endocrine therapy were ineligible. Overall survival and recurrence-free survival were the primary outcomes measured. Toxicity data was also collected and compared between the two groups. Of the 810 patients reviewed, 452 patients were analyzed in the study: 240 received tamoxifen and 212 received toremifene. The median and mean follow up times were 50.8 and 57.3 months, respectively. Toremifene and tamoxifen yielded similar overall survival values, with 5-year overall survival rates of 100% and 98.4%, respectively (p = 0.087). However, recurrence-free survival was significantly better in the toremifene group than in the tamoxifen group (p = 0.022). Multivariate analysis showed that recurrence-free survival improved independently with toremifene (HR = 0.385, 95% CI = 0.154-0.961; p = 0.041). Toxicity was similar in the two treatment groups with no women experiencing severe complications, other than hot flashes, which was more frequent in the toremifene patients (p = 0.049). No patients developed endometrial cancer. Toremifene may be a valid and

  4. Cancer of the larynx: the outcomes of conventionally fractionated radiotherapy in prospective and retrospective studies. Is the meaning of conventionality the same?

    International Nuclear Information System (INIS)

    Two studies on the radiotherapy of laryngeal cancer were completed at the Radiotherapy Department of the Cancer Center Warsaw at the end of 1999. One of them was a multicenter randomized clinical trial, and the second one - a retrospective study on patients treated between years 1989 and 1995. An opinion exists that the trial outcomes of the conventional arm correspond to the outcomes of everyday practice. The subject of the study was to evaluate this thesis, and to find out, whether the outcomes of prospective and retrospective studies following the same treatment protocol are comparable. Selection criteria were - age ≤75, WHO 0-1, T1, T2, T3, N0, M0 stage of glottic and supraglottic laryngeal cancer. The treatment was: 66 Gy/2 Gy/33 fraction/45 days. The prospective group had - 199 patients, and the retrospective group: 150 patients. The two groups were comparable according to the age, site, sex and mean hemoglobin level. There was a significant difference in T-stage and performance status between the two groups. Overall survival, local control and CR-response were analyzed. To eliminate the influence of the differences in T=stage and performance status, regression models were applied - Cox's for survival and local control, logit for CR-response endpoint. The protocol compliance (prospective, retrospective) was as follows - total dose: (88%, 49%), treatment time: (47%, 11%) respectively. Three-year survival for the prospective and the retrospective groups were 89% and 74%, respectively (p=0.035), CR-response rates were 96% and 75%, respectively (p<0.001). There were no significant differences in probability of local recurrence in CR patients. A better outcome of treatment was observed in the prospective study group. It is probably due to a certain 'over-selection' of patients for the prospective study and many deviations from the therapeutic protocol in the historical group. 'Conventional treatment' has the same meaning in the prospective and retrospective

    Full Text Available Abstract Background There is limited high-quality research investigating the efficacy of palliative radiation (PPR with regard to symptoms and quality of life (QOL among cancer patients with pelvic soft tissue tumors. As a result, clinicians are left with mainly retrospective studies, without reliable data on which to base treatment decisions. As a first step of a subsequent analysis of PPR's efficacy, we aimed to determine whether it is feasible to prospectively measure symptoms and QOL among patients treated with PPR. A secondary aim was to explore patients' willingness to answer existential questions in the setting of palliative pelvic radiation. Methods Patients referred for palliative radiation of soft-tissue pelvic tumors were invited to enter the study. Symptoms were scored by study physicians and QOL was assessed by the EORTC QLQ C-30 questionnaire and site specific modules (PR25, CR38 or BL24 prior to start of radiation and 6 and 12 weeks after its completion. In addition, patients answered existential questions at each of the study visits. A radiation therapist was available to participants in order to answer their questions and ensure that questionnaires were completed. Findings Five female and 17 male patients with prostate cancer (14, colorectal cancer (5 and bladder cancer (3 were included in the study. The median age of the participants was 75 years (range 62-90. Twenty patients were still in the study at the 6-week follow-up and 18 patients at the 12-week follow-up. Twenty-one patients had valid responses within all the EORTC QLQ C-30 scales at baseline, 20/20 at the 6-week follow-up and at the 12-week follow-up 17/18 patients still in the study had valid responses within all scales. This level of response was similar in the site-specific modules and among the existential questions.

    Full Text Available Background: The aim of this study was to assess the cosmetic outcome of patients undergoing oncoplastic breast conserving surgery in Indian population. Materials and Methods: A prospective cohort of 35 patients who were eligible for breast conservation surgery was included in the study from year 2007 to 2009. Patients with central quadrant tumors were excluded from the study. A double - blind cosmetic assessment was done by a plastic surgeon and a senior nurse not involved in the management of patients. Moreover, self-assessment was carried out by the patient regarding the satisfaction of surgery, comfort with brasserie, social and sexual life after oncoplastic surgery. Results: In this study, 35 patients underwent oncoplastic breast conservation surgery by various techniques. The cosmetic outcome scores of the surgeon and nurse were analyzed for inter rater agreement using inter-class Correlation Coefficients. There was a good association between them. The risk factors for poor cosmetic outcome was studied by univariate analysis and significant correlation was obtained with age, volume of breast tissue excised and estimated percentage of breast volume excised (P < 0.05. Moreover, 96% of patients were moderately to extremely satisfied with the surgery. Patients were offered an option for cosmetic correction of contralateral breast by mastopexy or reduction mammoplasty however, none of them agreed for another procedure. Conclusions: Oncoplastic breast surgery helps to resect larger volume of tissue with wider margins around the tumor. It helps to achieve better cosmesis and extends the indications for breast conservation. Most of the patients were satisfied with mere preservation of the breast mound rather than a symmetrical contralateral breast.

    Full Text Available Diabetes mellitus (DM has the potential to impact the pathogenesis, treatment, and outcome of pancreatic cancer. This study evaluates the impact of DM on pancreatic cancer survival.We conducted a retrospective cohort study from the Veterans Affairs (VA Central Cancer Registry (VACCR for pancreatic cancer cases between 1995 and 2008. DM and no-DM cases were identified from comorbidity data. Univariate and multivariable analysis was performed. Multiple imputation method was employed to account for missing variables.Of 8,466 cases of pancreatic cancer DM status was known in 4728 cases that comprised this analysis. Males accounted for 97.7% cases, and 78% were white. Overall survival was 4.2 months in DM group and 3.6 months in the no-DM group. In multivariable analysis, DM had a HR = 0.91 (0.849-0.974. This finding persisted after accounting for missing variables using multiple imputations method with the HR in DM group of 0.93 (0.867-0.997.Our data suggest DM is associated with a reduction in risk of death in pancreatic cancer. Future studies should be directed towards examining this association, specifically impact of DM medications on cancer outcome.

At the T3 follow-up, most of these effects were maintained. The intervention effect for BT specific coping strategies emerged for the Brief COPE ‘self-distraction’ and ‘behavioural disengagement’ domains, (p<0.05 for both. There were no adverse effects reported. A post-treatment social support program can improve physical and cognitive function and enhancing overall QoL of BT survivors. Social support programs need further evaluation and should be encouraged by clinicians within cancer rehabilitative services.

    Full Text Available The standard treatment in the early stage of maxillary sinus cancer is surgical resection followed by postoperative radiation therapy. However, for locally advanced maxillary sinus cancer, a multimodality treatment approach is strongly recommended to improve the survival rate and quality of life of the patient. We determined the treatment outcomes of induction chemotherapy, concurrent chemoradiation therapy, and surgical resection for locally advanced maxillary sinus cancer. Forty-four patients with locally advanced maxillary sinus cancer, who had been treated between January 1990 and April 2008 at Kangnam St. Mary's Hospital, were retrospectively analyzed. The objective response rates were 70%, 53%, and 57% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and concurrent chemoradiation therapy groups, respectively. The orbital preservation rates were 83%, 100%, and 75% in the intra-arterial induction chemotherapy, intravenous induction chemotherapy, and surgical resection groups, respectively. In seven of nine patients in whom the orbit could be preserved after induction chemotherapy, the primary tumors were removed completely. However, although the orbits were preserved in three patients who underwent surgical resection as a primary treatment, all three cases were confirmed to be incomplete resections. We found that active induction chemotherapy for locally advanced cancer of the maxillary sinus increased the possibility of complete resection with orbital preservation as well as tumor down-staging.

    Full Text Available Male breast cancer is an uncommon disease accounting for only 1% of all breast cancers. We present the evaluation, treatment and outcome of male patients seen with breast cancer in our institution. Male patients that had histological diagnosis of breast cancer from 2001 to 2010 were retrospectively evaluated. After evaluation patients were treated with modified radical mastectomy. Combination chemotherapy was given to patients with positive axillary lymph nodes. Radiotherapy and hormonal therapy were also employed. There were 57 male patients with breast cancer which accounted for 9% of all breast cancers seen during the study period. Their mean age was 59 ± 2.3 years. The mean tumor diameter was 13 ± 2.5 cm. Fifty three (93% patients presented with advanced disease including 15 with distant metastasis. Four patients with stage II disease were treated with modified radical mastectomy, chemotherapy and tamoxifen. Of the 30 patients with sage III disease that had modified radical mastectomy, complete axillary clearance and tumor free margins were achieved in 25. Overall 21 (36.8% patients were tumor free at one year. Overall 5-year survival was 22.8%. In conclusion, male patients with breast cancer present with advanced disease which is associated with poor outcome of treatment.

    Introduction Breast cancer (BC) is the most frequent cancer in Europe and the International Agency for Research on Cancer (IARC) has estimated over 460 000 incident cases per year. Survival among patients with BC has increased in the past decades and EUROCARE-5 has estimated a 5-year relative survival rate of 82% for patients diagnosed in 2000–2007. There is growing evidence that lifestyle (such as a diet based on Mediterranean principles associated with moderate physical activity) may influence prognosis of BC; however, this information is not currently available to patients and is not considered in oncology protocols. Only a few epidemiological studies have investigated the role of diet in BC recurrence and metastasis. Methods and analysis DianaWeb is a community-based participatory research dedicated to patients with BC and represents a collaborative effort between participants and research institutions to determine if specified changes in lifestyle would result in improved outcomes in terms of quality of life or survival. The aim of the study is to recruit a large number of participants, to monitor their lifestyle and health status over time, to provide them tips to encourage sustainable lifestyle changes, to analyse clinical outcomes as a function of baseline risk factors and subsequent changes, and to share with patients methodologies and results. DianaWeb uses a specific interactive website (http://www.dianaweb.org/) and, with very few exceptions, all communications will be made through the web. In this paper we describe the pilot study, namely DianaWeb in Umbria. Ethics and dissemination DianaWeb does not interfere with prescribed oncological treatments; rather, it recommends that participants should follow the received prescriptions. The results will be used to plan guidelines for nutrition and physical activity for patients with BC. The pilot study was approved by the ethics committee of the University of Perugia (reference number 2015-002), and is

    Cancer is a leading cause of death among adults in the United States. Only 54% of U.S. adults reported seeking cancer information in 2014. Cancer information seeking has been positively associated with cancer-related health outcomes such as screening adherence. We conducted a scoping review of studies that used data from the Health Information National Trends Survey (HINTS) in order to examine cancer information seeking in depth and the relationship between cancer information seeking and cancer-related health outcomes. We searched five databases and the HINTS website. The search yielded a total of 274 article titles. After review of 114 de-duplicated titles, 66 abstracts, and 50 articles, 22 studies met inclusion criteria. Cancer information seeking was the outcome in only four studies. The other 18 studies focused on a cancer-related health outcome. Cancer beliefs, health knowledge, and information seeking experience were positive predictors of cancer information seeking. Cancer-related awareness, knowledge, beliefs, preventive behaviors, and screening adherence were higher among cancer information seekers. Results from this review can inform other research study designs and primary data collection focused on specific cancer sites or aimed at populations not represented or underrepresented in the HINTS data (e.g., minority populations, those with lower socioeconomic status).

    Full Text Available Abstract Introduction African-American black men race is one of non-modifiable risk factors confirmed for prostate cancer. Many studies have been done in USA among African- American population to evaluate prostate cancer disparities. Compared to the USA very few data are available for prostate cancer in Sub-Saharan African countries. The objective of this study was to describe incident prostate cancer (PC diagnosis characteristics in Burkina Faso (West Africa. Methods We performed a prospective non randomized patient’s cohort study of new prostate cancer cases diagnosed by histological analysis of transrectal prostate biopsies in Burkina Faso. Study participants included 166 patients recruited at the urology division of the university hospital of Ouagadougou. Age of the patients, clinical symptoms, digital rectal examination (DRE result, serum prostate-specific antigen (PSA level, histological characteristics and TNM classification were taking in account in this study. Results 166 transrectal prostate biopsies (TRPB were performed based on high PSA level or abnormal DRE. The prostate cancer rate on those TRPB was 63, 8 % (n=106. The mean age of the patients was 71, 5 years (52 to 86. Urinary retention was the first clinical patterns of reference in our institution (55, 7 %, n = 59. Most patients, 56, 6 % (n = 60 had a serum PSA level over than 100 ng/ml. All the patients had adenocarcinoma on histological study of prostate biopsy cores. The majority of cases (54, 7 % n = 58 had Gleason score equal or higher than 7. Conclusion Prostate cancer is diagnosed at later stages in our country. Very high serum PSA level and poorly differentiated tumors are the two major characteristics of PC at the time of diagnosis.

    Background Studies of cardiac disease among adult survivors of childhood cancer have generally relied upon self-reported or registry-based data. Objective Systematically assess cardiac outcomes among childhood cancer survivors Design Cross-sectional Setting St. Jude Children's Research Hospital Patients 1,853 adult survivors of childhood cancer, ≥18 years old, and ≥10 years from treatment with cardiotoxic therapy for childhood cancer. Measurements History/physical examination, fasting metabolic and lipid panels, echocardiogram, electrocardiogram (ECG), 6-minute walk test (6MWT) all collected at baseline evaluation. Results Half (52.3%) of the survivors were male, median age 8.0 years (range: 0-24) at cancer diagnosis, 31.0 years (18-60) at evaluation. Cardiomyopathy was present in 7.4% (newly identified at the time of evaluation in 4.7%), coronary artery disease (CAD) in 3.8% (newly identified in 2.2%), valvular regurgitation/stenosis in 28.0% (newly identified in 24.8%), and conduction/rhythm abnormalities in 4.6% (newly identified in 1.4%). Nearly all (99.7%) were asymptomatic. The prevalences of cardiac conditions increased with age at evaluation, ranging from 3-24% among those 30-39 years to 10-37% among those ≥40 years. On multivariable analysis, anthracycline exposure ≥250 mg/m2 increased the odds of cardiomyopathy (odds ratio [OR] 2.7, 95% CI 1.1-6.9) compared to anthracycline unexposed survivors. Radiation to the heart increased the odds of cardiomyopathy (OR 1.9 95% CI 1.1-3.7) compared to radiation unexposed survivors. Radiation >1500 cGy with any anthracycline exposure conferred the greatest odds for valve findings. Limitations 61% participation rate of survivors exposed to cardiotoxic therapies, which were limited to anthracyclines and cardiac-directed radiation. A comparison group and longitudinal assessments are not available. Conclusions Cardiovascular screening identified considerable subclinical disease among adult survivors of childhood

    Full Text Available BACKGROUND: To evaluate the impact of diabetes on outcomes in colorectal cancer patients and to examine whether this association varies by the location of tumor (colon vs. rectum. PATIENTS AND METHODS: This study includes 4,131 stage I-III colorectal cancer patients, treated between 1995 and 2007 (12.5% diabetic, 53% colon, 47% rectal in South Korea. Cox proportional hazards modeling was used to determine the prognostic influence of DM on survival endpoints. RESULTS: Colorectal cancer patients with DM had significantly worse disease-free survival (DFS [hazard ratio (HR 1.17, 95% confidence interval (CI: 1.00-1.37] compared with patients without DM. When considering colon and rectal cancer independently, DM was significantly associated with worse overall survival (OS (HR: 1.46, 95% CI: 1.11-1.92, DFS (HR: 1.45, 95% CI: 1.15-1.84 and recurrence-free survival (RFS (HR: 1.32, 95% CI: 0.98-1.76 in colon cancer patients. No association for OS, DFS or RFS was observed in rectal cancer patients. There was significant interaction of location of tumor (colon vs. rectal cancer with DM on OS (P = 0.009 and DFS (P = 0.007. CONCLUSIONS: This study suggests that DM negatively impacts survival outcomes of patients with colon cancer but not rectal cancer.

  18. Outcome impact and cost-effectiveness of quality assurance for radiotherapy planned for the EORTC 22071–24071 prospective study for head and neck cancer

    International Nuclear Information System (INIS)

    Introduction: One of the goals of Quality Assurance in Radiotherapy (QART) is to reduce the variability and uncertainties related to treatment planning and beam delivery. The purpose of this study was to assess the outcome impact and cost-effectiveness (CE) of various QART levels for a head and neck (H and N) cancer study. Materials and methods: QART levels were defined as: basic QART with a dummy run (level 2), level 2 plus prospective Individual Case Reviews (ICRs) for 15% of patients (level 3) and level 2 plus prospective ICRs for all patients (level 4). The follow-up of patients was modeled using a multi-state model with parameters derived from EORTC, TROG and RTOG prospective studies. Individual patient data, linking QART results with outcome, were retrieved from the TROG database. Results for each QART level were expressed as percentage of mortality and local failure at 5 years. Results: Quality-of-life-adjusted and recurrence-free survival increased with increasing QART levels. The increase of all these metrics was more sizeable with an increased QART level from 2 or 3 to 4. The estimated quality-adjusted-life-years (QALYs) for an increase of QART levels of 3–4 and 2–4 were 0.09 and 0.15, respectively. The incremental CE ratio was €5525 and €3659 Euros per QALY for these QART levels. Compared to QART level 2 or 3, level 4 was cost-effective. Conclusions: Increasing QART levels resulted in better patient outcome in this simulated study. The increased complexity of the QART program was also cost-effective

    Full Text Available The Glasgow Prognostic Score (GPS is useful for predicting long-term mortality in cancer patients. Our aim was to validate the GPS in ED patients with different cancer-related urgency and investigate whether biomarkers would improve its accuracy. We followed consecutive medical patients presenting with a cancer-related medical urgency to a tertiary care hospital in Switzerland. Upon admission, we measured procalcitonin (PCT, white blood cell count, urea, 25-hydroxyvitamin D, corrected calcium, C-reactive protein, and albumin and calculated the GPS. Of 341 included patients (median age 68 years, 61% males, 81 (23.8% died within 30 days after admission. The GPS showed moderate prognostic accuracy (AUC 0.67 for mortality. Among the different biomarkers, PCT provided the highest prognostic accuracy (odds ratio 1.6 (95% confidence interval 1.3 to 1.9, P<0.001, AUC 0.69 and significantly improved the GPS to a combined AUC of 0.74 (P=0.007. Considering all investigated biomarkers, the AUC increased to 0.76 (P<0.001. The GPS performance was significantly improved by the addition of PCT and other biomarkers for risk stratification in ED cancer patients. The benefit of early risk stratification by the GPS in combination with biomarkers from different pathways should be investigated in further interventional trials.

  2. Impact of radiotherapy technique on the outcome of early breast cancer treated with conservative surgery: A multicenter observational study on 1,176 patients

    International Nuclear Information System (INIS)

    Purpose: To quantify the impact of radiotherapy technique on cosmetic outcome and on 5-year local control rate of early breast cancer treated with conservative surgery and adjuvant radiation. Methods and MaterialsPurpose: A total of 1,176 patients irradiated to the breast in 1997 were entered by eight centers into a prospective, observational study. Surgical procedure was quadrantectomy in 97% of patients, with axillary dissection performed in 96%; pT-stage was T1 in 81% and T2 in 19% of cases; pN-stage was N0 in 71%, N + (1-3) in 21%, and N + (>3) in 8% of cases. An immobilization device was used in 17% of patients; external contour-based and computed tomography-based treatment planning were performed in 20% and 72% of cases, respectively; 37% of patients were treated with a telecobalt unit and 63% with a linear accelerator; portal verification was used in 55% of patients; a boost dose to the tumor bed was delivered in 60% of cases. Results: With a median follow-up of 6.2 years, local, regional, and distant control rates at 5 years are 98%, 99%, and 92%, respectively. Use of less sophisticated treatment technique was associated with a less favorable cosmetic outcome. Local control was comparable between centers despite substantial technical differences. In a multivariate analysis including clinical and technical factors, only older age and prescription of medical adjuvant treatment significantly predicted for better local control, whereas use of portal verification was of borderline significance. Conclusions: Radiation technical factors impacted negatively on cosmetic outcome, but had relatively small effects on local control compared with other clinical factors

    Radioresistance is still an emerging problem for radiotherapy of oral cancer. Aberrant epigenetic alterations play an important role in cancer development, yet the role of such alterations in radioresistance of oral cancer is not fully explored. Using a methylation microarray, we identified promoter hypermethylation of FHIT (fragile histidine triad) in radioresistant OML1-R cells, established from hypo-fractionated irradiation of parental OML1 radiosensitive oral cancer cells. Further analysis confirmed that transcriptional repression of FHIT was due to promoter hypermethylation, H3K27me3 and overexpression of methyltransferase EZH2 in OML1-R cells. Epigenetic interventions or depletion of EZH2 restored FHIT expression. Ectopic expression of FHIT inhibited tumor growth in both in vitro and in vivo models, while also resensitizing radioresistant cancer cells to irradiation, by restoring Chk2 phosphorylation and G2/M arrest. Clinically, promoter hypermethylation of FHIT inversely correlated with its expression and independently predicted both locoregional control and overall survival in 40 match-paired oral cancer patient samples. Further in vivo therapeutic experiments confirmed that inhibition of DNA methylation significantly resensitized radioresistant oral cancer cell xenograft tumors. These results show that epigenetic silencing of FHIT contributes partially to radioresistance and predicts clinical outcomes in irradiated oral cancer. The radiosensitizing effect of epigenetic interventions warrants further clinical investigation. PMID:25460508

    2011-02-01

    Full Text Available Abstract Background Despite evidence that up to 35% of patients with cancer experience significant distress, access to effective psychosocial care is limited by lack of systematic approaches to assessment, a paucity of psychosocial services, and patient reluctance to accept treatment either because of perceived stigma or difficulties with access to specialist psycho-oncology services due to isolation or disease burden. This paper presents an overview of a randomised study to evaluate the effectiveness of a brief tailored psychosocial Intervention delivered by health professionals in cancer care who undergo focused training and participate in clinical supervision. Methods/design Health professionals from the disciplines of nursing, occupational therapy, speech pathology, dietetics, physiotherapy or radiation therapy will participate in training to deliver the psychosocial Intervention focusing on core concepts of supportive-expressive, cognitive and dignity-conserving care. Health professional training will consist of completion of a self-directed manual and participation in a skills development session. Participating health professionals will be supported through structured clinical supervision whilst delivering the Intervention. In the stepped wedge design each of the 5 participating clinical sites will be allocated in random order from Control condition to Training then delivery of the Intervention. A total of 600 patients will be recruited across all sites. Based on level of distress or risk factors eligible patients will receive up to 4 sessions, each of up to 30 minutes in length, delivered face-to-face or by telephone. Participants will be assessed at baseline and 10-week follow-up. Patient outcome measures include anxiety and depression, quality of life, unmet psychological and supportive care needs. Health professional measures include psychological morbidity, stress and burnout. Process evaluation will be conducted to assess perceptions

  5. A prospective study comparing the predictions of doctors versus models for treatment outcome of lung cancer patients: A step toward individualized care and shared decision making

    International Nuclear Information System (INIS)

    Background: Decision Support Systems, based on statistical prediction models, have the potential to change the way medicine is being practiced, but their application is currently hampered by the astonishing lack of impact studies. Showing the theoretical benefit of using these models could stimulate conductance of such studies. In addition, it would pave the way for developing more advanced models, based on genomics, proteomics and imaging information, to further improve the performance of the models. Purpose: In this prospective single-center study, previously developed and validated statistical models were used to predict the two-year survival (2yrS), dyspnea (DPN), and dysphagia (DPH) outcomes for lung cancer patients treated with chemo radiation. These predictions were compared to probabilities provided by doctors and guideline-based recommendations currently used. We hypothesized that model predictions would significantly outperform predictions from doctors. Materials and methods: Experienced radiation oncologists (ROs) predicted all outcomes at two timepoints: (1) after the first consultation of the patient, and (2) after the radiation treatment plan was made. Differences in the performances of doctors and models were assessed using Area Under the Curve (AUC) analysis. Results: A total number of 155 patients were included. At timepoint #1 the differences in AUCs between the ROs and the models were 0.15, 0.17, and 0.20 (for 2yrS, DPN, and DPH, respectively), with p-values of 0.02, 0.07, and 0.03. Comparable differences at timepoint #2 were not statistically significant due to the limited number of patients. Comparison to guideline-based recommendations also favored the models. Conclusion: The models substantially outperformed ROs’ predictions and guideline-based recommendations currently used in clinical practice. Identification of risk groups on the basis of the models facilitates individualized treatment, and should be further investigated in clinical

    This study assessed the psychosocial outcomes of adolescent cancer survivors and their relationship with personal and socio-familiar factors. Using a cross-sectional design, 41 survivors answered the four psychosocial dimensions of the KIDSCREEN-52 questionnaire and measures for social support and coping. Similarly, 41 parents answered coping and cancer-related distress measures. All psychosocial scores were within normative values (50 ± 10). Multiple linear regression analyses revealed four models with a range of explained variance between 9.4 percent and 31.9 percent that include the informative and emotional support, parental distress, and coping. This study contributes to the understanding of psychosocial outcomes of childhood cancer survivors and its correlates. PMID:25411198

  7. A preliminary outcome analysis of the patterns of care study in Japan for esophageal cancer patients with special reference to age: non surgery group

    International Nuclear Information System (INIS)

    Background: The Patterns of Care Study (PCS) was imported to Japan from the United States in July 1996. A preliminary outcome analysis of the PCS for esophageal cancer patients in Japan was made with special reference to age, because the elderly population is rapidly increasing in Japan. Patients and Methods: From July 1996 to February 1998, external PCS audits were performed for 37 institutions nationwide and detailed information of 561 esophageal cancer patients treated during the period 1992-1994 was collected by using the fifth PCS data format developed in the United States. This format was provided courtesy of the American College of Radiology. For this study, patients who had not undergone surgery (n = 336) were selected. The patients were classified into three age groups: < 65 years old (n = 119), between 65 and 74 years (n = 93), and 75 years or older (n =123). Cox's proportional hazards model was used for the statistical analysis, with survival, acute/subacute complication and late complication of grade 3 or more based on RTOG criteria, as the endpoints. Results: Significant prognostic factors for the entire non-surgery group were Karnofsky Performance Status (KPS) (p 0.0007), stage (p = 0.0001), and external irradiation dose (p = 0.0001). For the younger group, KPS (p = 0.0004), stage (p = 0.0197), and utilization of brachytherapy (p = 0.0010) were significant, while for the intermediate age group it was KPS (p = 0.0027), history of pulmonary disease (p = 0.0339), stage (p = 0.0001), and external dose (p = 0.0001), and for the elderly group, stage (p = 0.0001) and external irradiation dose (p = 0.0224) were significant. Significant risk factors for complications for the entire group were stage (p = 0.0411), external dose (p = 0.0163), and stratification of institution (academic vs. nonacademic) (p = 0.0114). Significant risk factors for the younger group were history of pulmonary disease (p = 0.0495) and external dose (p = 0.0037), and the other age

    Full Text Available OBJECTIVE: Xeroderma pigmentosum group D (XPD is an essential gene involved in the nucleotide excision repair (NER pathway. Two commonly studied single nucleotide polymorphisms (SNPs of XPD (Lys751Gln, A>C, rs13181; Asp312Asn, G>A, rs1799793 are implicated in the modulation of DNA repair capacity, thus related to the responses to platinum-based chemotherapy. Here we performed a meta-analysis to better evaluate the association between the two XPD SNPs and clinical outcome of platinum-based chemotherapy in non-small cell lung cancer (NSCLC patients. METHODS: A comprehensive search of PubMed database was conducted to identify relevant articles. Primary outcomes included objective response (i.e., complete response + partial response vs. stable disease + progressive disease, progression-free survival (PFS and overall survival (OS. The pooled and 95% confidence intervals (CIs of ORs (odds ratios and HRs (hazard ratios were estimated using the fixed or random effect model. RESULTS: Twenty-four studies were eligible according to the inclusion criteria. None of the XPD Lys751Gln/Asp312Asn polymorphisms was associated with objective response, PFS or OS in NSCLC patients treated with platinum drugs. However, in stratified analysis by ethnicity, the XPD Lys751Gln (A>C polymorphism was not significantly associated with increased response in Caucasians (OR=1.35, 95%CI=1.0-1.83, P=0.122 for heterogeneity but was associated with decreased PFS in Asians (HR=1.39, 95%CI=1.07-1.81, P=0.879 for heterogeneity. Furthermore, a statistically significant difference existed in the estimates of effect between the two ethnicities (P=0.014 for TR; PC may have inverse predictive and prognostic role in platinum-based treatment of NSCLC according to different ethnicities. Further studies are needed to validate our findings.

    Full Text Available Abstract Background Although 2-20% of breast cancer patients develop a contralateral breast cancer (CBC, prognosis after CBC is still debated. Using a unique patient cohort, we have investigated whether time interval to second breast cancer (BC2 and mode of detection are associated to prognosis. Methods Information on patient-, tumour-, treatment-characteristics, and outcome was abstracted from patients' individual charts for all patients diagnosed with metachronous CBC in the Southern Healthcare Region of Sweden from 1977-2007. Distant disease-free survival (DDFS and risk of distant metastases were primary endpoints. Results The cohort included 723 patients with metachronous contralateral breast cancer as primary breast cancer event. Patients with less than three years to BC2 had a significantly impaired DDFS (p = 0.01, and in sub-group analysis, this effect was seen primarily in patients aged Conclusions In a large cohort of patients with CBC, we found the time interval to BC2 to be a strong prognostic factor for DDFS in young women and mode of detection to be related to risk of distant metastases. Future studies of tumour biology of BC2 in relation to prognostic factors found in the present study can hopefully provide biological explanations to these findings.

    2016-08-01

    Cancer therapy requires anticancer agents capable of efficient and uniform systemic delivery. One promising route to their development is nanotechnology. Here, a previous model for cancer chemotherapy based on a nanosized drug carrier (Paiva et al., 2011) is extended by including tissue vasculature and a three-dimensional growth. We study through computer simulations the therapy against tumors demanding either large or small nutrient supplies growing under different levels of tissue vascularization. Our results indicate that highly vascularized tumors demand more aggressive therapies (larger injected doses administrated at short intervals) than poorly vascularized ones. Furthermore, nanoparticle endocytic rate by tumor cells, not its selectivity, is the major factor that determines the therapeutic success. Finally, our finds indicate that therapies combining cytotoxic agents with antiangiogenic drugs that reduce the abnormal tumor vasculature, instead of angiogenic drugs that normalize it, can lead to successful treatments using feasible endocytic rates and administration intervals.

    Unlike acute lymphoblastic leukemia (ALL) in infants, MLL gene rearrangement (MLL-r) is rare in ALL children (≥1 year old). The outcome and optimal treatment options for MLL-r ALL remain controversial. Among the 1827 children enrolled in the Tokyo Children's Cancer Study Group ALL studies L95-14, L99-15, L99-1502, L04-16, and L07-1602 (1995-2009), 25 MLL-r ALL patients (1.3 %) were identified. Their median age and leukocyte count at diagnosis was 2 years old (range 1-15 years) and 27,690/μL (range 1800-1,113,000/μL), respectively. All but one patient achieved complete remission (CR) after induction therapy, and 19 underwent allogeneic hematopoietic stem cell transplantation (HSCT) in first CR according to the protocol. The 5-year event-free survival (EFS) and overall survival (OS) rate were 60.0 % [standard error (SE), 9.7 %] and 64.0 % (SE 9.6 %), respectively. Notably, 9/12 cases with MLL-AF4-positive ALL are alive in continuous CR with a 75.0 % (SE 12.5 %) EFS rate. The causes of treatment failure were as follows: one induction failure, five relapses, and five transplant-related deaths. With intensive chemotherapy and allogeneic HSCT, favorable outcome of children (≥1 year old) with MLL-AF4-positive ALL was observed. However, considering the risk of acute and late toxicities associated with HSCT, its indication should be restricted. PMID:26410102

  13. Atypical and Malignant Meningioma: Outcome and Prognostic Factors in 119 Irradiated Patients. A Multicenter, Retrospective Study of the Rare Cancer Network

    International Nuclear Information System (INIS)

    Purpose: To retrospectively analyze and assess the outcomes and prognostic factors in a large number of patients with atypical and malignant meningiomas. Methods and Materials: Ten academic medical centers participating in this Rare Cancer Network contributed 119 cases of patients with atypical or malignant meningiomas treated with external beam radiotherapy (EBRT) after surgery or for recurrence. Eligibility criteria were histologically proven atypical or anaplastic (malignant) meningioma (World Health Organization Grade 2 and 3) treated with fractionated EBRT after initial resection or for recurrence, and age >18 years. Sex ratio (male/female) was 1.3, and mean (±SD) age was 57.6 ± 12 years. Surgery was macroscopically complete (Simpson Grades 1-3) in 71% of patients; histology was atypical and malignant in 69% and 31%, respectively. Mean dose of EBRT was 54.6 ± 5.1 Gy (range, 40-66 Gy). Median follow-up was 4.1 years. Results: The 5- and 10-year actuarial overall survival rates were 65% and 51%, respectively, and were significantly influenced by age >60 years (p = 0.005), Karnofsky performance status (KPS) (p = 0.01), and high mitotic rate (p = 0.047) on univariate analysis. On multivariate analysis age >60 years (p = 0.001) and high mitotic rate (p = 0.02) remained significant adverse prognostic factors. The 5- and 10-year disease-free survival rates were 58% and 48%, respectively, and were significantly influenced by KPS (p 0.04) and high mitotic rate (p = 0.003) on univariate analysis. On multivariate analysis only high mitotic rate (p = 0.003) remained a significant prognostic factor. Conclusions: In this multicenter retrospective study, age, KPS, and mitotic rate influenced outcome. Multicenter prospective studies are necessary to clarify the management and prognostic factors of such a rare disease

  14. Real-world outcomes of postmastectomy radiotherapy in breast cancer patients with 1–3 positive lymph nodes. A retrospective study

    International Nuclear Information System (INIS)

    To assess the treatment outcomes and to explore the determinants of clinical outcome in breast cancer patients with 1–3 positive nodes who did or did not receive postmastectomy radiotherapy (PMRT) in a tertiary care referral cancer center in Northern Thailand. We investigated a retrospective cohort of registered breast cancer patients at the Faculty of Medicine, Chiang Mai University, Thailand from 2001–2007. Analysis was performed using Cox regression models to identify factors affecting the overall survival (OS) and relapse-free survival (RFS) rates. Comparisons were made between two cohorts: women who received adjuvant PMRT (74 patients) and women who did not receive adjuvant PMRT (81 patients). A total of 155 patients were included with a median follow-up period of 4.45 years. There was a statistically significant 4-year OS difference between the two groups of patients: 100% for the PMRT group and 93.1% for the non-PMRT group (P = 0.044). The 4-year RFS was 85.9% for patients receiving PMRT and 78.3% for patients who did not receive PMRT (P = 0.291). On multivariate analysis of OS, using hormonal treatment was the only significant independent factor associated with improved OS. On multivariate analysis of RFS, none of the variables were significantly associated with improved RFS. PMRT was notfound to be a prognostic variable related to the outcome of patients using a logistic regression model. Our retrospective, hospital-based analysis demonstrated that PMRT improved the treatment outcome in terms of OS for women with 1–3 node positive early-stage breast cancer. (author)

  18. Rectal Toxicity After Proton Therapy For Prostate Cancer: An Analysis of Outcomes of Prospective Studies Conducted at the University of Florida Proton Therapy Institute

    International Nuclear Information System (INIS)

    Purpose: Study goals were to characterize gastrointestinal effects of proton therapy (PT) in a large cohort of patients treated for prostate cancer, identify factors associated with rectal bleeding (RB), and compare RB between patients receiving investigational protocols versus those in outcome-tracking protocols. Methods and Materials: A total of 1285 consecutive patients were treated with PT between August 2006 and May 2010. Potential pre-existing clinical and treatment-related risk factors for rectal toxicity were recorded. Common Terminology Criteria for Adverse Events version 3.0 was used to score toxicity. Results: Transient RB was the predominant grade 2 or higher (GR2+) toxicity after PT, accounting for 95% of gastrointestinal events. GR1 RB occurred in 217 patients (16.9%), GR2 RB in 187 patients (14.5%), and GR3 in 11 (0.9%) patients. There were no GR4 or GR5 events. Univariate analyses showed correlations between GR2+ RB and anticoagulation therapy (P=.008) and rectal and rectal wall dose-volume histogram (DVH) parameters (P<.001). On multivariate analysis, anticoagulation therapy (P=.0034), relative volume of rectum receiving 75 Gy (V75; P=.0102), and relative rectal wall V75 (P=.0017) were significant predictors for G2+ RB. Patients treated with investigational protocols had toxicity rates similar to those receiving outcome-tracking protocols. Conclusions: PT was associated with a low rate of GR2+ gastrointestinal toxicity, predominantly transient RB, which was highly correlated with anticoagulation and rectal DVH parameters. Techniques that limit rectal exposure should be used when possible

  19. Process of care and preliminary outcome in limited-stage small-cell lung cancer: results of the 1995-1997 patterns of care study in Japan

    International Nuclear Information System (INIS)

    Purpose: To evaluate the practice process using the national average (Na); to compare differences in the process of care by age group; and to provide a preliminary outcome data for limited-stage small-cell lung cancer in Japan. Methods and Materials: The Patterns of Care Study conducted a nationwide survey of the care process for Stage I-III small-cell lung cancer in Japan. Patients were divided into three age groups: <65 years (younger group, n = 73); between 65 and 74 years (intermediate group, n = 81); and ≥75 years (elderly group, n = 20). Results: The NA for the total dose was 49.0 Gy, and for use of photon energy ≥6 MV, chemotherapy, and prophylactic cranial irradiation was 77.3%, 93.2%, and 1.69%, respectively. Age stratification had no impact on the variables of radiotherapy (RT) such as total dose and field size. Only 37% of patients received chemotherapy and thoracic RT concurrently. The proportion of patients who received chemotherapy and RT concurrently was 44%, 27%, and 25% of the younger, intermediate, and elderly groups, respectively (p = 0.029). Etoposide and cisplatin were less frequently used in the elderly group (≥75 years old). Overall survival at 3 years for the entire group was 26%. The 3-year survival rate was 30% in the younger group, 28% in the intermediate group, and 9% in the elderly group. Variables found to have a significant impact on survival by multivariate analysis were the use of chemotherapy (p = 0.030), age (p 0.032), and T stage (p = 0.042). Conclusion: Calculated NAs showed that the results of clinical study had favorably penetrated into the practice process in Japan. The results demonstrated that patient age significantly influenced the process of chemotherapy such as the use of etoposide and cisplatin for limited-stage small-cell lung cancer in Japan. More concurrent chemotherapy and thoracic RT and the application of prophylactic cranial irradiation for complete responders need to be investigated in the future

    AIM: To determine the immediate surgical outcome and recovery of bowel function following posterior pelvic exenteration (PPE) for primary rectal cancer with suspected local invasion to the female internal reproductive organs, in comparison with a case-control series of standard resection for primary rectal cancer.METHODS: We analyzed 10 consecutive female patientsundergoing PPE for the aforementioned indicationbetween December 2003 and May 2006 in a singleinstitution. Data were prospectively collected duringhospitalization, including patient demographics, tumor-and operation-related variables and early surgicaloutcomes. These patients were compared with a groupof female patients, matched for age, co-morbidity andlocation of tumor, who underwent standard resection for primary rectal cancer in the same period (non PPE group).RESULTS: In the PPE group, pathological reports showed direct invasion of the reproductive organs in 4 cases and an involvement of lymph nodes in 7 cases. A sphincter-saving operation was performed in each case.Operative time was longer (274 min vs 157 min, P <0.001) and blood loss was greater (769 mL vs 203 mL,P = 0.008) in the PPE group. Time to first bowelmovement, time to first defecation, time to resumptionof normal diet, and hospital stay were not significantlydifferent between the two groups. Postoperativecomplication rates were also similar.CONCLUSION: PPE for rectal cancer was associatedwith longer operative time and increased blood loss,but did not compromise immediate surgical outcomes and postoperative bowel function compared to standard rectal resection.

  1. Modern Outcomes of Inflammatory Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To report contemporary outcomes for inflammatory breast cancer (IBC) patients treated in the modern era of trastuzumab and taxane-based chemotherapy. Methods and Materials: We retrospectively reviewed the charts of 104 patients with nonmetastatic IBC treated between January 2000 and December 2009. Patients who received chemotherapy, surgery, and radiation therapy were considered to have completed the intended therapy. Kaplan-Meier curves estimated locoregional control (LRC), distant metastases-free survival (DMFS), and overall survival. Results: The median follow-up time was 34 months; 57 (55%) patients were estrogen receptor progesterone receptor (ER/PR) negative, 34 (33%) patients were human epidermal growth factor receptor 2 (her2)/neu amplified, and 78 (75%) received definitive postoperative radiation. Seventy-five (72%) patients completed all of the intended therapy, of whom 67 (89%) received a taxane and 18/28 (64%) of her2/neu-amplified patients received trastuzumab. For the entire cohort, the 5-year rates of overall survival, LRC, and DMFS were 46%, 83%, and 44%, respectively. The ER/PR-negative patients had a 5-year DMFS of 39% vs. 52% for ER/PR-positive patients (p = 0.03). The 5-year DMFS for patients who achieved a pathologic complete response compared with those who did not was 83% vs. 44% (p 60.4 Gy (n = 15) to the chest wall had a 5-year LRC rate of 100% vs. 83% for those who received 45 to 60.4 Gy (n = 49; p = 0.048). On univariate analysis, significant predictors of DMFS included achieving a complete response to neoadjuvant chemotherapy (hazard ratio [HR] = 5.8; 95% confidence interval [CI] = 1.4–24.4; p = 0.02) and pathologically negative lymph nodes (HR = 4.1; 95% CI = 1.4–11.9; p 60.4 Gy to the chest wall. Despite the use of taxanes and trastuzumab, outcomes remain modest, particularly for those with ER/PR-negative disease and those without a pathologic complete response.

    Full Text Available Abstract Background The objective of this study was to examine the extent of surgical procedures, pathological findings, complications and outcome of patients treated in the last 12 years for gallbladder cancer. Methods The impact of a standardized more aggressive approach compared with historical controls of our center with an individual approach was examined. Of 53 patients, 21 underwent resection for cure and 32 for palliation. Results Overall hospital mortality was 9% and procedure related mortality was 4%. The standardized approach in UICC stage IIa, IIb and III led to a significantly improved outcome compared to patients with an individual approach (Median survival: 14 vs. 7 months, mean+/-SEM: 26+/-7 vs. 17+/-5 months, p = 0.014. The main differences between the standardized and the individual approach were anatomical vs. atypical liver resection, performance of systematic lymph dissection of the hepaticoduodenal ligament and the resection of the common bile duct. Conclusion Anatomical liver resection, proof for bile duct infiltration and, in case of tumor invasion, radical resection and lymph dissection of the hepaticoduodenal ligament are essential to improve outcome of locally advanced gallbladder cancer.

    Full Text Available Aim: To report the prevalence and outcomes of pressure ulcers (PU seen in a cohort of cancer patients requiring home-based palliative care. Materials and Methods: All patients referred for home care were eligible for this prospective observational study, provided they were living within a distance of 35 km from the institute and gave informed consent. During each visit, caregivers were trained and educated for providing nursing care for the patient. Dressing material for PU care was provided to all patients free of cost and care methods were demonstrated. Factors influencing the occurrence and healing of PUs were analyzed using logistic regression. Duration for healing of PU was calculated using the Kaplan Meier method. P < 0.05 are taken as significant. Results: Twenty-one of 108 (19.4% enrolled patients had PU at the start of homecare services. None of the patients developed new PU during the course of home care. Complete healing of PU was seen in 9 (42.9% patients. The median duration for healing of PU was found to be 56 days. Median expenditure incurred in patients with PU was Rs. 2323.40 with a median daily expenditure of Rs. 77.56. Conclusions: The present model of homecare service delivery was found to be effective in the prevention and management of PUs. The high prevalence of PU in this cohort indicates a need for greater awareness for this complication. Clinical Trial Registry Number: CTRI/2014/03/004477

    BACKGROUND There are several studies examining prostate cancer and exposure to cadmium, iron, selenium, and zinc. Less data are available on the possible influence of these metal ions on prostate cancer outcome. This study measured levels of these ions in prostatectomy samples in order to examine possible associations between metal concentrations and disease outcome. METHODS We obtained formalin fixed paraffin embedded tissue blocks of prostatectomy samples of 40 patients with PSA recurrence, matched 1:1 (for year of surgery, race, age, Gleason grading, and pathology TNM classification) with tissue blocks from 40 patients without recurrence (n = 80). Case-control pairs were compared for the levels of metals in areas adjacent to tumors. Inductively coupled plasma-mass spectrometry (ICP-MS) was used for quantification of Cd, Fe, Zn, and Se. RESULTS Patients with biochemical (PSA) recurrence of disease had 12% lower median iron (95 ??g/g vs. 111 ??g/g; P = 0.04) and 21% lower zinc (279 ??g/g vs. 346 ??g/g; P = 0.04) concentrations in the normal-appearing tissue immediately adjacent to cancer areas. Differences in cadmium (0.489 ??g/g vs. 0.439 ??g/g; 4% higher) and selenium (1.68 ??g/g vs. 1.58 ??g/g; 5% higher) levels were not statistically significant in recurrence cases, when compared to non-recurrences (P = 0.40 and 0.21, respectively). CONCLUSIONS There is an association between low zinc and low iron prostate tissue levels and biochemical recurrence in prostate cancer. Whether these novel findings are a cause or effect of more aggressive tumors, or whether low zinc and iron prostatic levels raise implications for therapy, remains to be investigated.

However, conducting a highly ranked in the evidence hierarchy pyramid is not easy or feasible at all times and places. There remains a room for descriptive clinical outcome measure studies with admitting the limit of the intepretation. Aims: Presents three Korean clinic based outcome measure studies with a view to encouraging Korean clinicians to conduct similar studies. Methods: Three studies are presented briefly here including 1 Quality of Life of liver cancer patients after 8 Constitutional acupuncture; 2 Developing a Korean version of Measuring yourself Medical Outcome profile (MYMOP; and 3 Survey on 5 Shu points: a pilot In the first study, we have included 4 primary or secondary liver cancer patients collecting their diagnostic X-ray film and clinical data f개m their hospital, and asked them to fill in the European Organization Research and Treatment of Cancer, Quality of Life Questionnaire before the commencement of the treatment. The acupuncture treatment is set up format but not disclosed yet. The translation and developing a Korean version of outcome measures that is Korean clinician friendly has been sought for MYMOP is one of the most appropriate one. The permission was granted, the translation into Korean was done, then back translated into English only based on the Korean translation by the researcher who is bilingual in both languages. The back translation was compared by the original developer of MYMOP and confirmed usable. In order to test the existence of acupoints and meridians through popular forms of Korean acupuncture regimes, we aim at collecting opinions from 101 Korean clinicians that have used those forms. The questions asked include most effective symptoms, 5 Shu points, points those are least likely to use due to either adverse events or the lack of effectiveness, theoretical reasons for the above proposals, proposing outcome measures

  9. Negative predictive value of multiparametric MRI for prostate cancer detection: Outcome of 5-year follow-up in men with negative findings on initial MRI studies

    International Nuclear Information System (INIS)

    Highlights: • We assess the negative predictive value of multiparametric MRI for prostate cancer. • Patients with positive prostate biopsy findings were defined as false-negative. • Patients with negative initial prostate biopsy findings were followed up for 5 years. • The negative predictive value was 89.6% for significant prostate cancer. • MRI is a useful tool to rule out significant prostate cancer before biopsy. - Abstract: Objective: To assess the clinical negative predictive value (NPV) of multiparametric MRI (mp-MRI) for prostate cancer in a 5-year follow-up. Materials and methods: One hundred ninety-three men suspected of harboring prostate cancer with negative MRI findings were included. Patients with positive transrectal ultrasound (TRUS)-guided biopsy findings were defined as false-negative. Patients with negative initial TRUS-guided biopsy findings were followed up and only patients with negative findings by digital rectal examination, MRI, and repeat biopsy and no increase in PSA at 5-year follow-up were defined as “clinically negative”. The clinical NPV of mp-MRI was calculated. For quantitative analysis, mean signal intensity on T2-weighted images and the mean apparent diffusion coefficient value on ADC maps of the initial MRI studies were compared between peripheral-zone (PZ) cancer and the normal PZ based on pathologic maps of patients who had undergone radical prostatectomy. Results: The clinical NPV of mp-MRI was 89.6% for significant prostate cancer. Small cancers, prostatitis, and benign prostatic hypertrophy masking prostate cancer returned false-negative results. Quantitative analysis showed that there was no significant difference between PZ cancer and the normal PZ. Conclusion: The mp-MRI revealed a high clinical NPV and is a useful tool to rule out clinically significant prostate cancer before biopsy

    Highlights: • We assess the negative predictive value of multiparametric MRI for prostate cancer. • Patients with positive prostate biopsy findings were defined as false-negative. • Patients with negative initial prostate biopsy findings were followed up for 5 years. • The negative predictive value was 89.6% for significant prostate cancer. • MRI is a useful tool to rule out significant prostate cancer before biopsy. - Abstract: Objective: To assess the clinical negative predictive value (NPV) of multiparametric MRI (mp-MRI) for prostate cancer in a 5-year follow-up. Materials and methods: One hundred ninety-three men suspected of harboring prostate cancer with negative MRI findings were included. Patients with positive transrectal ultrasound (TRUS)-guided biopsy findings were defined as false-negative. Patients with negative initial TRUS-guided biopsy findings were followed up and only patients with negative findings by digital rectal examination, MRI, and repeat biopsy and no increase in PSA at 5-year follow-up were defined as “clinically negative”. The clinical NPV of mp-MRI was calculated. For quantitative analysis, mean signal intensity on T2-weighted images and the mean apparent diffusion coefficient value on ADC maps of the initial MRI studies were compared between peripheral-zone (PZ) cancer and the normal PZ based on pathologic maps of patients who had undergone radical prostatectomy. Results: The clinical NPV of mp-MRI was 89.6% for significant prostate cancer. Small cancers, prostatitis, and benign prostatic hypertrophy masking prostate cancer returned false-negative results. Quantitative analysis showed that there was no significant difference between PZ cancer and the normal PZ. Conclusion: The mp-MRI revealed a high clinical NPV and is a useful tool to rule out clinically significant prostate cancer before biopsy.

    Introduction Sub-Saharan African (SSA) women with breast cancer (BC) have low survival rates from this potentially treatable disease. An understanding of context-specific societal, health-systems and woman-level barriers to BC early detection, diagnosis and treatment are needed. Methods The African Breast Cancer—Disparities in Outcomes (ABC-DO) is a prospective hospital-based study of overall survival, impact on quality of life (QOL) and delays along the journey to diagnosis and treatment of BC in SSA. ABC-DO is currently recruiting in Namibia, Nigeria, South Africa, Uganda and Zambia. Women aged 18 years or older who present at participating secondary and tertiary hospitals with a new clinical or histocytological diagnosis of primary BC are invited to participate. For consented women, tumour characteristics, specimen and treatment data are obtained. Over a 2-year enrolment period, we aim to recruit 2000 women who, in the first instance, will be followed for between 1 and 3 years. A face-to-face baseline interview obtains information on socioeconomic, cultural and demographic factors, QOL, health and BC attitudes/knowledge, and timing of all prediagnostic contacts with caregivers in orthodox health, traditional and spiritual systems. Responses are immediately captured on mobile devices that are fed into a tailored mobile health (mHealth) study management system. This system implements the study protocol, by prompting study researchers to phone women on her mobile phone every 3 months and, failing to reach her, prompts contact with her next-of-kin. At follow-up calls, women provide updated information on QOL, care received and disease impacts on family and working life; date of death is asked of her next-of-kin when relevant. Ethics and dissemination The study was approved by ethics committees of all involved institutions. All participants provide written informed consent. The findings from the study will be published in peer-reviewed scientific journals

  18. Locoregional Treatment Outcomes After Multimodality Management of Inflammatory Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: The aims of this study were to determine outcomes for patients with inflammatory breast cancer (IBC) treated with multimodality therapy, to identify factors associated with locoregional recurrence, and to determine which patients may benefit from radiation dose escalation. Methods and Materials: We retrospectively reviewed 256 consecutive patients with nonmetastatic IBC treated at our institution between 1977 and 2004. Results: The 192 patients who were able to complete the planned course of chemotherapy, mastectomy, and postmastectomy radiation had significantly better outcomes than the 64 patients who did not. The respective 5-year outcome rates were: locoregional control (84% vs. 51%), distant metastasis-free survival (47% vs. 20%), and overall survival (51% vs. 24%) (p < 0.0001 for all comparisons). Univariate factors significantly associated with locoregional control in the patients who completed plan treatment were response to neoadjuvant chemotherapy, surgical margin status, number of involved lymph nodes, and use of taxanes. Increasing the total chest-wall dose of postmastectomy radiation from 60 Gy to 66 Gy significantly improved locoregional control for patients who experienced less than a partial response to chemotherapy, patients with positive, close, or unknown margins, and patients <45 years of age. Conclusions: Patients with IBC who are able to complete treatment with chemotherapy, mastectomy, and postmastectomy radiation have a high probability of locoregional control. Escalation of postmastectomy radiation dose to 66 Gy appears to benefit patients with disease that responds poorly to chemotherapy, those with positive, close, or unknown margin status, and those <45 years of age

    Emergency presentation of rectal cancer carries a relatively poor prognosis, but the roles and interactions of causative factors remain unclear. We describe an innovative statistical approach which distinguishes between direct and indirect effects of a number of contextual, patient and tumour factors on emergency presentation and outcome of rectal cancer. All patients diagnosed with rectal cancer in Ireland 2004-2008 were included. Registry information, linked to hospital discharge data, provided data on patient demographics, comorbidity and health insurance; population density and deprivation of area of residence; tumour type, site, grade and stage; treatment type and optimality; and emergency presentation and hospital caseload. Data were modelled using a structural equation model with a discrete-time survival outcome, allowing us to estimate direct and mediated effects of the above factors on hazard, and their inter-relationships. Two thousand seven hundred and fifty patients were included in the analysis. Around 12% had emergency presentations, which increased hazard by 80%. Affluence, private patient status and being married reduced hazard indirectly by reducing emergency presentation. Older patients had more emergency presentations, while married patients, private patients or those living in less deprived areas had fewer than expected. Patients presenting as an emergency were less likely to receive optimal treatment or to have this in a high caseload hospital. Apart from stage, emergency admission was the strongest determinant of poor survival. The factors contributing to emergency admission in this study are similar to those associated with diagnostic delay. The socio-economic gradient found suggests that patient education and earlier access to endoscopic investigation for public patients could reduce emergency presentation. PMID:27087482

  20. Focal salvage iodine-125 brachytherapy for prostate cancer recurrences after primary radiotherapy: A retrospective study regarding toxicity, biochemical outcome and quality of life

    International Nuclear Information System (INIS)

    Purpose: Whole-gland salvage for recurrent prostate cancer (PCa) shows high failure and toxicity rates. Early and adequate localization of recurrences enables focal salvage, thereby potentially improving functional outcomes, while maintaining cancer control. Materials and methods: Retrospective analysis yielded 20 focal salvage I125 brachytherapy patients for locally recurrent PCa after primary radiotherapy. Tumor was defined by multiparametric MRI and correspondence with transrectal biopsies. Dose data were obtained intra-operatively. The tumor was prescribed ⩾144 Gy. Toxicity was scored by the Common Terminology Criteria for Adverse Events version 4 (CTCAE-4). Biochemical failure (BF) was defined using the Phoenix criteria (PSA-nadir + 2.0 ng/ml). Quality of life (QoL) was measured by SF-36 Health Survey and European Organization of Research and Treatment of Cancer (EORTC) C30+3 and PR25 questionnaires. Results: With a median follow-up of 36 months (range 10–45), six patients experienced BF, of which three had no initial response. Grade 3 genitourinary (GU) toxicity occurred in one patient (a urethral stricture). The five previously potent patients retained erectile function. QoL remained decreased with regard to urinary symptoms. Conclusion: Focal salvage I125 brachytherapy showed one grade 3 GU toxicity in the 20 treated patients. Biochemical response and QoL were acceptable

  2. Tumor tissue levels of Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and outcome following adjuvant chemotherapy in premenopausal lymph node-positive breast cancer patients: A retrospective study

    International Nuclear Information System (INIS)

    We have previously demonstrated that high tumor tissue levels of TIMP-1 are associated with no or limited clinical benefit from chemotherapy with CMF and anthracyclines in metastatic breast cancer patients. Here, we extend our investigations to the adjuvant setting studying outcome after adjuvant chemotherapy in premenopausal lymph node-positive patients. We hypothesize that TIMP-1 high tumors are less sensitive to chemotherapy and accordingly that high tumor tissue levels are associated with shorter survival. From our original retrospectively collected tumor samples we selected a group of 525 pre-menopausal lymph node-positive patients (adjuvant treatment: CMF, 324 patients; anthracycline-based, 99 patients; no adjuvant chemotherapy, 102 patients). TIMP-1 levels were measured using ELISA in cytosolic extracts of frozen primary tumors. TIMP-1 was analyzed as a continuous variable and as a dichotomized one using the median TIMP-1 concentration as a cut point between high and low TIMP-1 groups. We analyzed the benefit of adjuvant CMF and anthracyclines in univariate and multivariable survival models; endpoints were disease-free (DFS) and overall survival (OS). In this selected cohort of high-risk patients, and in the subgroup of patients receiving no adjuvant therapy, TIMP-1 was not associated with prognosis. In the subgroup of patients treated with anthracyclines, when analyzed as a continuous variable we observed a tendency for increasing TIMP-1 levels to be associated with shorter DFS (multivariable analysis, HR 1.75, 95% CI 1.00-3.07, P = 0.05) and a significant association between increasing TIMP-1 and shorter OS in both univariate (HR 3.52, 95% CI 1.54-8.06, P = 0.003) and multivariable analyses (HR 4.19, 95% CI 1.67-10.51, P = 0.002). No statistically significant association between TIMP-1 and DFS was observed in the CMF-treated patients although high TIMP-1 was associated with shorter OS when analyzed as a dichotomized variable (HR 1.64, 95% CI 1.02-2.65, P

  3. PD-L1 expression in human cancers and its association with clinical outcomes.

    PD-L1 is an immunoinhibitory molecule that suppresses the activation of T cells, leading to the progression of tumors. Overexpression of PD-L1 in cancers such as gastric cancer, hepatocellular carcinoma, renal cell carcinoma, esophageal cancer, pancreatic cancer, ovarian cancer, and bladder cancer is associated with poor clinical outcomes. In contrast, PD-L1 expression correlates with better clinical outcomes in breast cancer and merkel cell carcinoma. The prognostic value of PD-L1 expression in lung cancer, colorectal cancer, and melanoma is controversial. Blocking antibodies that target PD-1 and PD-L1 have achieved remarkable response rates in cancer patients who have PD-L1-overexpressing tumors. However, using PD-L1 as an exclusive predictive biomarker for cancer immunotherapy is questionable due to the low accuracy of PD-L1 immunohistochemistry staining. Factors that affect the accuracy of PD-L1 immunohistochemistry staining are as follows. First, antibodies used in different studies have different sensitivity. Second, in different studies, the cut-off value of PD-L1 staining positivity is different. Third, PD-L1 expression in tumors is not uniform, and sampling time and location may affect the results of PD-L1 staining. Therefore, better understanding of tumor microenvironment and use of other biomarkers such as gene marker and combined index are necessary to better identify patients who will benefit from PD-1/PD-L1 checkpoint blockade therapy.

    Gastric cancer is the fourth most common cancer and second most common cause of cancer death worldwide. Globally, gastric cancer poses a significant public health burden - both economically and socially. In 2008, the economic burden from premature cancer deaths and disability was $895 billion and gastric cancer was the second highest cancer responsible for healthy life lost. With the expected increase in cancer deaths and non-communicable diseases, these costs are expected to rise and impact patient care. World Health Organization, estimates a 15% increase in non-communicable disease worldwide, with more than 20% increase occurring in Africa between 2010 and 2020. Mali, West Africa, is ranked 15(th) highest incidence of gastric cancer worldwide at a rate of 20.3/100000, yet very scarce published data evaluating etiology, prevention or management exist. It is understood that risk factors of gastric cancer are multifactorial and include infectious agents (Helicobacter pylori, Epstein-Barr virus), genetic, dietary, and environmental factors (alcohol, smoking). Interestingly, African patients with gastric cancer are younger, in their 3(rd)-4(th) decade, and present at a late stage of the disease. There is sparse data regarding gastric cancer in Africa due to lack of data collection and under-reporting, which impacts incidence and mortality rates. Currently, GLOBOCAN, an International Agency for Research on Cancer resource, is the most comprehensive available resource allowing comparison between nations. In resource limited settings, with already restricted healthcare funding, data is needed to establish programs in Africa that increase gastric cancer awareness, curtail the economic burden, and improve patient management and survival outcomes.

    Full Text Available PURPOSE: The optimal management of patients with clinical stage I non-seminomatous germ cell testicular cancer (NSGCT I was considered controversial until the European Germ Cell Cancer Consensus Group determined unambiguous treatment strategies. In order to assess the long-term outcome we evaluated the data of patients with NSGCT I. MATERIALS AND METHODS: In a retrospective evaluation, we included 52 patients with a mean age of 26 years (range 15-58 who were treated with different modalities at our department between 1989 and 2003. Mean follow-up was 5.9 years (range 2-14 years. After orchiectomy, 39 patients were treated with chemotherapy, 7 patients underwent retroperitoneal lymph node dissection and 6 men were managed using a surveillance strategy. Survival, recurrence rate and time of recurrence were evaluated. The histological staging and treatment modality was related to the relapse. RESULTS: Tumor specific overall mortality was 3.8%. The mortality and relapse rate of the surveillance strategy, retroperitoneal lymph node dissection and chemotherapy was 16.7% / 50%, 14.3% / 14.3% and 0% / 2.5% respectively. All relapsed patients in the surveillance group as well as in the RPLND group had at least one risk factor for developing metastatic disease. CONCLUSIONS: Following the European consensus on diagnosis and treatment of germ cell cancer in patients with NSGCT Stage I any treatment decision must be individually related to the patient according to prognostic factors and care capacity of the treating centre. In case of doubt, adjuvant chemotherapy should be the treatment of choice, as it provides the lowest risk of relapse or tumor related death.

  8. Twice-Weekly Hypofractionated Intensity-Modulated Radiotherapy for Localized Prostate Cancer With Low-Risk Nodal Involvement: Toxicity and Outcome From a Dose Escalation Pilot Study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the toxicity and preliminary outcome of patients with localized prostate cancer treated with twice-weekly hypofractionated intensity-modulated radiotherapy (IMRT). Methods and Materials: Between 2003 and 2006, 82 prostate cancer patients with a nodal involvement risk ≤20% (Roach index) have been treated to the prostate with or without seminal vesicles with 56 Gy (4 Gy/fraction twice weekly) and an overall treatment time of 6.5 weeks. Acute and late genitourinary (GU) and gastrointestinal (GI) toxicities were scored according to the Radiation Therapy Oncology Group (RTOG) grading system. Median follow-up was 48 months (range, 9-67 months). Results: All patients completed the treatment without interruptions. No patient presented with Grade ≥3 acute GU or GI toxicity. Of the patients, 4% presented with Grade 2 GU or GI persistent acute toxicity 6 weeks after treatment completion. The estimated 4-year probability of Grade ≥2 late GU and GI toxicity-free survival were 94.2% ± 2.9% and 96.1% ± 2.2%, respectively. One patient presented with Grade 3 GI and another patient with Grade 4 GU late toxicity, which were transitory in both cases. The 4-year actuarial biochemical relapse-free survival was 91.3% ± 5.9%, 76.4% ± 8.8%, and 77.5% ± 8.9% for low-, intermediate-, and high-risk groups, respectively. Conclusions: In patients with localized prostate cancer, acute and late toxicity were minimal after dose-escalation administering twice-weekly 4 Gy to a total dose of 56 Gy, with IMRT. Further prospective trials are warranted to further assess the best fractionation schemes for these patients.

  9. Association of TMPRSS2-ERG gene fusion with clinical characteristics and outcomes: results from a population-based study of prostate cancer

    International Nuclear Information System (INIS)

    The presence of the TMPRSS2-ERG fusion gene in prostate tumors has recently been associated with an aggressive phenotype, as well as recurrence and death from prostate cancer. These associations suggest the hypothesis that the gene fusion may be used as a prognostic indicator for prostate cancer. In this study, fluorescent in situ hybridization (FISH) assays were used to assess TMPRSS2-ERG fusion status in a group of 214 prostate cancer cases from two population-based studies. The FISH assays were designed to detect both fusion type (deletion vs. translocation) and the number of fusion copies (single vs. multiple). Genotyping of four ERG and one TMPRSS2 SNPs using germline DNA was also performed in a sample of the cases (n = 127). Of the 214 tumors scored for the TMPRSS2-ERG fusion, 64.5% were negative and 35.5% were positive for the fusion. Cases with the TMPRSS2-ERG fusion did not exhibit reduced prostate cancer survival (HR = 0.92, 95% CI = 0.22–3.93), nor was there a significant difference in cause-specific survival when stratifying by translocation or deletion (HR = 0.84, 95% CI = 0.23–3.12) or by the number of retained fusion copies (HR = 1.22, 95% CI = 0.45–3.34). However, evidence for reduced prostate cancer-specific survival was apparent in those cases whose tumor had multiple copies of the fusion. The variant T allele of the TMPRSS2 SNP, rs12329760, was positively associated with TMPRSS2-ERG fusion by translocation (p = 0.05) and with multiple copies of the gene fusion (p = 0.03). If replicated, the results presented here may provide insight into the mechanism by which the TMPRSS2-ERG gene fusion arises and also contribute to diagnostic evaluations for determining the subset of men who will go on to develop metastatic prostate cancer

    Full Text Available Abstract Background In Australia, breast cancer is the most common cancer affecting Australian women. Inequalities in clinical and psychosocial outcomes have existed for some time, affecting particularly women from rural areas and from areas of disadvantage. We have a limited understanding of how individual and area-level factors are related to each other, and their associations with survival and other clinical and psychosocial outcomes. Methods/Design This study will examine associations between breast cancer recurrence, survival and psychosocial outcomes (e.g. distress, unmet supportive care needs, quality of life. The study will use an innovative multilevel approach using area-level factors simultaneously with detailed individual-level factors to assess the relative importance of remoteness, socioeconomic and demographic factors, diagnostic and treatment pathways and processes, and supportive care utilization to clinical and psychosocial outcomes. The study will use telephone and self-administered questionnaires to collect individual-level data from approximately 3, 300 women ascertained from the Queensland Cancer Registry diagnosed with invasive breast cancer residing in 478 Statistical Local Areas Queensland in 2011 and 2012. Area-level data will be sourced from the Australian Bureau of Statistics census data. Geo-coding and spatial technology will be used to calculate road travel distances from patients' residence to diagnostic and treatment centres. Data analysis will include a combination of standard empirical procedures and multilevel modelling. Discussion The study will address the critical question of: what are the individual- or area-level factors associated with inequalities in outcomes from breast cancer? The findings will provide health care providers and policy makers with targeted information to improve the management of women with breast cancer, and inform the development of strategies to improve psychosocial care for women

    Full Text Available Cervical cancer is the most fatal disease among Indonesian women. In recognition of the substantial variation in the intrinsic response of individuals to radiation, an effort had been done to identify the genetic markers, primarily Single Nucleotide polymorphisms (SNPs, which are associated with responsiveness of cancer cells to radiation therapy. One of these SNPs is X-ray repair cross-complementing protein 1 (XRCC1 that is one of the most important genes in deoxyribonucleic acid (DNA repair pathways. Meta-analysis in the determination of the association of XRCC1 polymorphisms with cervical cancer revealed the potential role of XRCC1 polymorphisms in predicting cell response to radiotherapy.Our preliminary study with real-time polymerase chain reaction (RT-PCR showed that radiotherapy affected the XRCC1 gene analyzed in blood of cervical cancer patient. Other published study found three SNPs of XRCC1 (Arg194Trp, Arg280His, and Arg399Gln that cause amino acid substitutions. Arg194Trp is only SNPs that associated with high risk of cervical cancer but not others. Additionally, structure and function of this protein can be altered by functional SNPs, which may lead to the susceptibility of individuals to cancers. Anotherstudy found G399A polymorphisms. We concluded that SNP of this DNA repair genes have been found to be good predictors of efficacy of radiotherapy.Kanker serviks adalah penyakit yang paling fatal pada perempuan di Indonesia.

  13. Cancer cervix?: a retrospective study

    International Nuclear Information System (INIS)

    Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

    Amplification of the human epidermal growth factor receptor 2 (HER2) gene occurs in approximately 20% of invasive breast cancer cases and is associated with a more aggressive disease course than HER2-negative breast cancer. HER2-targeted therapies have altered the natural history of HER2-positive breast cancer, a trend that will likely further improve with the recent approval of new agents. A prospective, observational cohort study was designed and initiated to provide real-world insights into current treatment patterns, long-term survival, and patients’ experiences with initial and subsequent treatments for HER2-positive metastatic breast cancer (MBC). The Systematic Therapies for HER2-positive Metastatic Breast Cancer Study (SystHERs) is a US-based prospective observational cohort study enrolling patients ≥18 years of age with recently diagnosed HER2-positive MBC not previously treated with systemic therapy in the metastatic setting. The primary objective of the study is to identify treatment patterns and clinical outcomes in recently diagnosed patients in a variety of practice settings. Secondary objectives include comparative efficacy, safety, and patient-reported outcomes (PROs). Healthcare resource utilization is an exploratory end point. Tumor tissue and blood sample collection is optional. The SystHERs registry will enroll approximately 1000 patients over a 3-year period, after which the study will continue for ≥5 years, allowing for a maximum follow-up of 8 years. The treating physician will determine all care and the frequency of visits. PRO measures will be completed at study enrollment and every 90 days. Clinical data will be abstracted quarterly from patient records. The first patient was enrolled in June 2012, and preliminary descriptive data based on 25% to 30% of the final study population are expected at the end of 2013, and as of April 25, 2014, 386 patients are enrolled. SystHERs is expected to provide in-depth data on demographic

  15. Improving outcomes in lung cancer: the value of the multidisciplinary health care team

    Full Text Available Eve Denton,1 Matthew Conron2 1Allergy, Immunology and Respiratory Department, Alfred Hospital, 2Department of Respiratory and Sleep Medicine, St Vincent's Hospital, Melbourne, VIC, Australia Abstract: Lung cancer is a major worldwide health burden, with high disease-related morbidity and mortality. Unlike other major cancers, there has been little improvement in lung cancer outcomes over the past few decades, and survival remains disturbingly low. Multidisciplinary care is the cornerstone of lung cancer treatment in the developed world, despite a relative lack of evidence that this model of care improves outcomes. In this article, the available literature concerning the impact of multidisciplinary care on key measures of lung cancer outcomes is reviewed. This includes the limited observational data supporting improved survival with multidisciplinary care. The impact of multidisciplinary care on other benchmark measures of quality lung cancer treatment is also examined, including staging accuracy, access to diagnostic investigations, improvements in clinical decision making, better utilization of radiotherapy and palliative care services, and improved quality of life for patients. Health service research suggests that multidisciplinary care improves care coordination, leading to a better patient experience, and reduces variation in care, a problem in lung cancer management that has been identified worldwide. Furthermore, evidence suggests that the multidisciplinary model of care overcomes barriers to treatment, promotes standardized treatment through adherence to guidelines, and allows audit of clinical services and for these reasons is more likely to provide quality care for lung cancer patients. While there is strengthening evidence suggesting that the multidisciplinary model of care contributes to improvements in lung cancer outcomes, more quality studies are needed. Keywords: lung cancer, multidisciplinary care, mortality, tumor board

  18. SU-E-J-95: Predicting Treatment Outcomes for Prostate Cancer: Irradiation Responses of Prostate Cancer Stem Cells

    International Nuclear Information System (INIS)

    Purpose: Most prostate cancers are slow-growing diseases but normally require much higher doses (80Gy) with conventional fractionation radiotherapy, comparing to other more aggressive cancers. This study is to disclose the radiobiological basis of this discrepancy by proposing the concept of prostate cancer stem cells (CSCs) and examining their specific irradiation responses. Methods: There are overwhelming evidences that CSC may keep their stemness, e.g. the competency of cell differentiation, in hypoxic microenvironments and hence become radiation resistive, though the probability is tiny for aggressiveness cancers. Tumor hypoxia used to be considered as an independent reason for poor treatment outcomes, and recent evidences showed that even prostate cancers were also hypoxic though they are very slow-growing. In addition, to achieve comparable outcomes to other much more aggressive cancers, much higher doses (rather than lower doses) are always needed for prostate cancers, regardless of its non-aggressiveness. All these abnormal facts can only be possibly interpreted by the irradiation responses characteristics of prostate CSCs. Results: Both normal cancer cells (NCCs) and CSCs exiting in tumors, in which NCCs are mainly for symptoms whereas killing all CSCs achieves disease-free. Since prostate cancers are slow-growing, the hypoxia in prostate cancers cannot possibly from NCCs, thus it is caused by hypoxic CSCs. However, single hypoxic cell cannot be imaged due to limitation of imaging techniques, unless a large group of hypoxic cells exist together, thus most of CSCs in prostate cancers are virtually hypoxic, i.e. not in working mode because CSCs in proliferating mode have to be normoxic, and this explains why prostate cancers are unaggressive. Conclusion: The fractional dose in conventional radiotherapy (∼2Gy) could only kill NCCs and CSCs in proliferating modes, whereas most CSCs survived fractional treatments since they were hypoxic, thus to eliminate all

  20. Health-related quality of life outcome for oral cancer survivors after surgery and postoperative radiotherapy

    International Nuclear Information System (INIS)

    Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)

High incidence and survival rates for prostate cancer have resulted in a large and growing population of long-term prostate cancer survivors. Long-term follow-up guidelines have only recently been developed to inform approaches to this phase of care for the prostate cancer population. Methods: A PubMed search of English literature through August 2014 was performed. Articles were retrieved and reviewed to confirm their relevance. Patient-reported measures that were used in studies of long-term prostate cancer survivors (ie, at least 2 years posttreatment were reviewed and included in the review. Results: A total of 343 abstracts were initially identified from the database search. After abstract review, 105 full-text articles were reviewed of which seven met inclusion criteria. An additional 22 articles were identified from the references of the included articles, and 29 were retained. From the 29 articles, 68 patient-reported outcome measures were identified. The majority (75% were multi-item scales that had been previously validated in existing literature. We identified four main areas of assessment: 1 physical health; 2 quality of life – general, physical, and psychosocial; 3 health promotion – physical activity, diet, and tobacco cessation; and 4 care quality outcomes. Conclusion: There are a number of well-validated measures that assess patient-reported outcomes that document key aspects of long-term follow-up with respect to patient symptoms and quality of life.

  7. Outcome After Pulmonary Radiotherapy in Wilms' Tumor Patients With Pulmonary Metastases at Diagnosis: A UK Children's Cancer Study Group, Wilms' Tumour Working Group Study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the effect of whole lung radiotherapy on event-free and overall survival of children with Stage IV Wilms' tumor with pulmonary metastases at diagnosis and to ascertain factors that may have led to the decision to withhold radiotherapy. Methods and Materials: We compared recurrence and mortality risks of patients with pulmonary metastases at diagnosis enrolled in the UKW2 and UKW3 clinical trials (1986-2001) according to treatment with pulmonary radiotherapy. Results: Of 102 eligible patients (43 patients in UKW2 and 59 patients in UKW3), 72 (71%) received pulmonary radiotherapy; 30 (29%) did not. After a median follow-up of 9.3 years (range, 0.6-14.1 years), event-free survival was 79.2% (95% confidence interval [CI], 67.8-86.9%) in patients who received pulmonary radiotherapy compared with 53.3% (95% CI, 34.3-69.1%) in patients who did not receive it (p = 0.006), with a hazard ratio of 2.66 (95% CI, 1.28-5.52; p = 0.009). There was no difference in overall survival (84.7% [95% CI, 74.1-91.2%] vs. 73.2% [95% CI, 53.4-85.6%], respectively; p = 0.157). Pulmonary radiotherapy reduced the chance of lung relapse (8.3% vs. 23.3%; p = 0.039). The omission of radiotherapy did not seem to be consistently associated with any specific clinical or radiologic features. Conclusions: Outcome may be compromised if pulmonary radiotherapy is omitted in children with Wilms' tumor with pulmonary metastases. There was a significant effect on event-free survival; the risk of an event, particularly lung recurrence, was increased nearly threefold. Strategies for selection of children for avoidance of pulmonary irradiation need to be developed in a controlled fashion

    Full Text Available Context : Cancer survival has improved significantly and maintaining fertility is both a major concern and an important factor for the quality of life in cancer patients. Aims : To explore differences in oocyte stimulation for fertility preservation (FP patients based on cancer diagnosis. Settings and Deign : Between 2005 and 2011, 109 patients elected to pursue FP at a single institution. Materials and Method : In vitro fertilization (IVF outcome variables between four cancer diagnostic groups (breast, gynecologic, lymphoma/leukemia and other and age-matched male factor or tubal factor infertility IVF control group were compared. Statistical Analysis : ANOVA and Chi-square analyses were employed to compare variables between the groups that were normally distributed. Kruskal-Wallis with subsequent Mann-Whitney U-test were used for data that were not normally distributed. Results : Women with gynecologic malignancies were significantly older than the women in the other three groups, but tended to have a better ovarian response. Women with hematologic malignancies were most likely to have been exposed to chemotherapy and had the longest stimulations with a similar number of oocytes retrieved. The age-matched IVF controls had higher peak estradiol levels, number of oocytes obtained, and fertilization rates when compared to cancer patients with or without a history of prior chemotherapy. Conclusions : Factors including age, type of cancer and chemotherapy exposure, can influence response to ovarian stimulation. Discussing these findings with patients presenting for FP may aid in setting realistic treatment expectations.

    Each day, more than 12.5 million health-related computer searches are conducted on the World Wide Web. Based on a meta-analysis of 24 published surveys, the author estimates that in the developed world, about 39% of persons with cancer are using the Internet, and approximately 2.3 million persons living with cancer worldwide are online. In addition, 15% to 20% of persons with cancer use the Internet "indirectly" through family and friends. Based on a comprehensive review of the literature, the available evidence on how persons with cancer are using the Internet and the effect of Internet use on persons with cancer is summarized. The author distinguishes four areas of Internet use: communication (electronic mail), community (virtual support groups), content (health information on the World Wide Web), and e-commerce. A conceptual framework summarizing the factors involved in a possible link between Internet use and cancer outcomes is presented, and future areas for research are highlighted. PMID:15224975

    A retrospective analysis was performed to investigate the radioprotective effects of amifostine on the long-term outcome of radiation therapy for patients with carcinoma of the uterine cervix. Eighty-three patients with histologically proven epidermoid carcinoma (Stage II-IVA disease) of the uterine cervix were treated with definite radiation therapy between January 1978 and December 1984. Forty-six patients were treated with radiation alone, whereas 37 patients were treated with radiation plus amifostine daily from the initiation of the course of radiation therapy. The median total dose of amifostine given was 1300 mg/m[sub 2], with a range of 280 mg/m[sup 2] to 3700 mg/m[sup 2]. The 5-year overall actuarial survival for the patients treated with radiation along and with radiation plus amifostine were: 72% and 88% in Stage II disease (p = 0.45); 52% and 50% in Stage III disease (p = 0.68); and 40% and 43% in Stage IVA disease (p = 0.51), respectively. The 5-year intra-pelvic recurrence rates in the patients treated with amifostine were almost the same as those observed in the patients treated without amifostine (0% vs. 6% in Stage II disease; 15% vs. 10% in Stage III disease; 25% vs. 40% in Stage IVA disease). There was also no statistically significant difference of the chronic rectal or bladder complication rate between the groups treated by each regimen. The authors concluded that any radioprotective effects of amifostine on tumor tissue and any beneficial effects of amifostine against chronic radiation injury were not observed in the patients with cervical cancer followed up for more than 5 years after radiation therapy. 17 refs., 3 figs., 3 tabs.

    International Nuclear Information System (INIS)

    The incidence and associated factors of loose seed migration were investigated in cohort 1 of the Japanese Prostate Cancer Outcome Study of Permanent Iodine-125 Seed Implantation (J-POPS). The study subjects were 2160 patients, consisting of 1641 patients who underwent permanent iodine-125 seed implantation (PI) and 519 patients who underwent PI combined with external beam radiation therapy (PI + EBRT). The presence or absence of seed migration to the chest and abdominal/pelvic region was determined. Seed migration was observed in 22.7 % of PI group patients and 18.1 % of PI + EBRT group patients (p = 0.0276). Migration to the lungs and abdominal/pelvic region was observed in 14.6 % and 11.1 % of the patients in the PI group, and 11.2 % and 8.5 % of the patients in the PI + EBRT group, respectively. In the PI group, the number of implanted seeds was associated with the seed migration incidence. Neither the PI nor the PI + EBRT group showed any difference in the volume of the prostate receiving 100 % of the prescribed dose (V100 [%]) or the minimal dose received by 90 % of the prostate volume (D90 [Gy]) between the patients with and without seed migration. This prospective cohort study investigating the largest number of past cases showed no difference in D90 (Gy) or V100 (%) between seed migration or the absence thereof in both the PI group and PI + EBRT group

    International Nuclear Information System (INIS)

    The background of this study was to determine the clinical results of radiotherapy (RT) for esophageal cancer in Japan. A questionnaire-based survey was conducted for esophageal cancer treated by definitive RT between 1999 and 2003. Clinical results of definitive RT for patients were collected from 9 major institutions. Only patients with good performance status (PS 0-2) who received a total dose of 50 Gy or more were included. Patients were classified into three groups: (A) stage I, (B) resectable stages II-III, (C) unresectable stages III-IVA. For group A, all patients treated by RT alone or chemo-radiotherapy (CRT) were included. For groups B and C, only those treated by CRT were included. In total, 167 patients were included in group A, 239 in group B, and 244 in group C. Approximately half of the patients in group A were treated by CRT. The median total RT dose ranged from 60 to 66 Gy. The median and range of the 5-year overall survival rates were 56% (48-83%) for group A, 29% (12-52%) for group B, and 19% (0-31%) for group C, respectively. A wide disparity in overall survival rates was noted among the institutions. A significant correlation between the number of patients treated per year and the 5-year overall survival rate was noted for groups B and C (both p<0.05). Although the overall survival rates for stage I esophageal cancer were excellent, a significant disparity in survival rates was noted among the institutions for stage II-IVA tumors treated by CRT.

    For many years, transfusion of allogeneic red blood cells, platelet concentrates, and plasma units has been part of the standard therapeutic arsenal used along the surgical and nonsurgical treatment of patients with malignancies. Although the benefits of these blood products are not a matter of debate in specific pathological conditions associated with life-threatening low blood cell counts or bleeding, increasing clinical evidence is nevertheless suggesting that deliberate transfusion of these blood components may actually lead to negative clinical outcomes by affecting patient's immune defense, stimulating tumor growth, tethering, and dissemination. Rigorous preclinical and clinical studies are needed to dimension the clinical relevance, benefits, and risks of transfusion of blood components in cancer patients and understand the amplitude of problems. There is also a need to consider validating preparation methods of blood components for so far ignored biological markers, such as microparticles and biological response modifiers. Meanwhile, blood component transfusions should be regarded as a personalized medicine, taking into careful consideration the status and specificities of the patient, rather than as a routine hospital procedure.

    Aims Altered expression of epithelial or stromal caveolin-1 (Cav-1) is observed in various types of human cancers. However, the clinical significance of Cav-1 expression in gastric cancer (GC) remains largely unknown. The present study aims to explore the clinicopathological significance and prognostic value of both tumor cells and cancer associated fibroblasts (CAFs) Cav-1 in GC. Methods and Results Quantum dots immunofluorescence histochemistry was performed to examine the expression of Cav-1 in 20 cases of gastritis without intestinal metaplasia (IM), 20 cases of gastritis with IM and 286 cases of GC. Positive rates of epithelial Cav-1 in gastritis without IM, gastritis with IM and GC showed a decreasing trend (P = 0.012). Low expression of Cav-1 in CAFs but not in tumor cells was an independent predictor of poor prognosis in GC patients (P = 0.034 and 0.005 respectively in disease free survival and overall survival). Cav-1 level in tumor cells and CAFs showed no significant correlation with classic clinicopathological features. Conclusions Loss of epithelial Cav-1 may promote malignant progression and low CAFs Cav-1 level herald worse outcome of GC patient, suggesting CAFs Cav-1 may be a candidate therapeutic target and a useful prognostic marker of GC.

  18. Bilateral breast cancer: an evaluation of risk factors and outcome

    International Nuclear Information System (INIS)

    PURPOSE: To compare the outcome of bilateral breast cancer patients to that of patients with unilateral disease. MATERIALS AND METHODS: From 1960-1995, 1254 stage O/I/II/III patients with primary breast cancer were treated by either mastectomy or breast conservation therapy at Thomas Jefferson University Hospital. There were 1141 (91.2%) unilateral, 41 (3.1%) synchronous and 65 (5.7%) metachronous breast cancer patients. Synchronous breast cancers were defined as having a second cancer diagnosis within one year of initial diagnosis. There were 46.2% of patients stage O/I at initial diagnosis, while 68% were stage O/I at subsequent diagnosis. For the metachronous breast cancers, the median interval between first and second diagnosis was 44 months (range of 13-287 months). Median follow-up time was 58 months for the synchronous cancers (15-218 months) and 107 months (21-360 months) for the metachronous cancers. Overall and NED survival, local control and distant metastatic disease rates from the time of the first and second diagnosis were calculated for the synchronous and metachronous patients. These were then compared to the unilateral breast cancer patients and to each other. RESULTS: Synchronous bilateral breast cancer patients had a worse 5 and 10 year NED survival rate (71.2% and 57.0%) compared to the unilateral patients (83.8% and 77.8%) p=.015 and also a higher distant metastasis rate (70.6% and 54.9% vs. 83.5% and 77.8%) (p=.005). Local control and overall survival comparisons were not statistically significant in this group when compared to unilateral patients. There was also no difference noted when comparing metachronous to unilateral patients for the above parameters. When analyzing metachronous and synchronous patients there was a trend revealing a worse NED survival at 5 and 10 years (84.5% and 82.2% vs. 71.2% and 57% p=.07) and a higher metastatic rate (85.9% and 80.9% vs. 70.6% and 54.9% p=.01) in the synchronous group. CONCLUSION: We conclude that

  20. Mature Results of the Ottawa Phase II Study of Intermittent Androgen-Suppression Therapy in Prostate Cancer: Clinical Predictors of Outcome

    International Nuclear Information System (INIS)

    Purpose: To present the mature experience of a phase II trial of intermittent androgen suppression (IAS). Methods and Materials: Intermittent androgen-suppression therapy was initiated in prostate-cancer patients to delay hormone resistance and minimize potential side effects of androgen-deprivation therapy (ADT). Patients received cyclical periods of ADT and observation (off-treatment interval [OTI]). Androgen-deprivation therapy was reinitiated when the level of prostate-specific antigen (PSA) rose above 10 ng/ml, or for disease progression. Associations between clinical factors and eligibility for OTI were measured. Kaplan-Meier and Cox regression analyses were used to determine factors predicting the duration of OTIs. Results: Ninety-five patients completed 187 cycles of treatment. The median duration of OTIs was 8.5 months. Patients with higher PSA and metastatic disease were less likely to be eligible for the first OTI (p < 0.01). In multivariate analysis, patients with higher PSA and local relapse had significantly longer OTIs (p < 0.01) compared with metastatic patients. The median time to withdrawal from the study was 37 months. Conclusions: Intermittent androgen suppression appears to be a favorable treatment option for patients with biochemically (according to level of PSA) or locally recurrent prostate cancer with favorable long-term survival, a high probability of eligibility for OTIs, and durable OTIs

    Full Text Available 'Taste' changes are commonly reported during chemotherapy. It is unclear to what extent this relates to actual changes in taste function or to changes in appetite and food liking and how these changes affect dietary intake and nutritional status.This prospective, repeated measures cohort study recruited participants from three oncology clinics. Women (n = 52 prescribed adjuvant chemotherapy underwent standardised testing of taste perception, appetite and food liking at six time points to measure change from baseline. Associations between taste and hedonic changes and nutritional outcomes were examined.Taste function was significantly reduced early in chemotherapy cycles (p<0.05 but showed recovery by late in the cycle. Ability to correctly identify salty, sour and umami tastants was reduced. Liking of sweet food decreased early and mid-cycle (p<0.01 but not late cycle. Liking of savory food was not significantly affected. Appetite decreased early in the cycle (p<0.001. Reduced taste function was associated with lowest kilojoule intake (r = 0.31; p = 0.008 as was appetite loss with reduced kilojoule (r = 0.34; p = 0.002 and protein intake (r = 0.36; p = 0.001 early in the third chemotherapy cycle. Decreased appetite early in the third and final chemotherapy cycles was associated with a decline in BMI (p = <0.0005 over the study period. Resolution of taste function, food liking and appetite was observed 8 weeks after chemotherapy completion. There was no association between taste change and dry mouth, oral mucositis or nausea.The results reveal, for the first time, the cyclical yet transient effects of adjuvant chemotherapy on taste function and the link between taste and hedonic changes, dietary intake and nutritional outcomes. The results should be used to inform reliable pre-chemotherapy education.

    2012-12-01

    Full Text Available Abstract Background In breast cancer, diabetes diagnosed prior to cancer (previously diagnosed is associated with advanced cancer stage and increased mortality. However, in the general population, 40% of diabetes is undiagnosed until glucose testing, and evidence suggests one consequence of increased evaluation and management around breast cancer diagnosis is the increased detection of previously undiagnosed diabetes. Biological factors – for instance, higher insulin levels due to untreated disease - and others underlying the association between previously diagnosed diabetes and breast cancer could differ in those whose diabetes remains undiagnosed until cancer. Our objectives were to identify factors associated with previously undiagnosed diabetes in breast cancer, and to examine associations between previously undiagnosed diabetes and cancer stage, treatment patterns, and mortality. Methods Using Surveillance, Epidemiology, and End Results-Medicare, we identified women diagnosed with breast cancer and diabetes between 01/2001 and 12/2005. Diabetes was classified as previously diagnosed if it was identified within Medicare claims between 24 and 4 months before cancer diagnosis, and previously undiagnosed if it was identified from 3 months before to ≤ 3 months after cancer. Patients were followed until 12/2007 or death, whichever came first. Multivariate analyses were performed to examine risk factors for previously undiagnosed diabetes and associations between undiagnosed (compared to previously diagnosed diabetes, cancer stage, treatment, and mortality. Results Of 2,418 patients, 634 (26% had previously undiagnosed diabetes; the remainder had previously diagnosed diabetes. The mean age was 77.8 years, and 49.4% were diagnosed with in situ or stage I disease. Age > 80 years (40% of the cohort and limited health system contact (primary care physician and/or preventive services prior to cancer were associated with higher adjusted odds of

  3. Patient-Reported Voice and Speech Outcomes After Whole-Neck Intensity Modulated Radiation Therapy and Chemotherapy for Oropharyngeal Cancer: Prospective Longitudinal Study

    International Nuclear Information System (INIS)

    Purpose: To describe voice and speech quality changes and their predictors in patients with locally advanced oropharyngeal cancer treated on prospective clinical studies of organ-preserving chemotherapy–intensity modulated radiation therapy (chemo-IMRT). Methods and Materials: Ninety-one patients with stage III/IV oropharyngeal cancer were treated on 2 consecutive prospective studies of definitive chemoradiation using whole-field IMRT from 2003 to 2011. Patient-reported voice and speech quality were longitudinally assessed from before treatment through 24 months using the Communication Domain of the Head and Neck Quality of Life (HNQOL-C) instrument and the Speech question of the University of Washington Quality of Life (UWQOL-S) instrument, respectively. Factors associated with patient-reported voice quality worsening from baseline and speech impairment were assessed. Results: Voice quality decreased maximally at 1 month, with 68% and 41% of patients reporting worse HNQOL-C and UWQOL-S scores compared with before treatment, and improved thereafter, recovering to baseline by 12-18 months on average. In contrast, observer-rated larynx toxicity was rare (7% at 3 months; 5% at 6 months). Among patients with mean glottic larynx (GL) dose ≤20 Gy, >20-30 Gy, >30-40 Gy, >40-50 Gy, and >50 Gy, 10%, 32%, 25%, 30%, and 63%, respectively, reported worse voice quality at 12 months compared with before treatment (P=.011). Results for speech impairment were similar. Glottic larynx dose, N stage, neck dissection, oral cavity dose, and time since chemo-IMRT were univariately associated with either voice worsening or speech impairment. On multivariate analysis, mean GL dose remained independently predictive for both voice quality worsening (8.1%/Gy) and speech impairment (4.3%/Gy). Conclusions: Voice quality worsening and speech impairment after chemo-IMRT for locally advanced oropharyngeal cancer were frequently reported by patients, underrecognized by clinicians, and

  5. The outcome of a multi-centre feasibility study of online adaptive radiotherapy for muscle-invasive bladder cancer TROG 10.01 BOLART

    International Nuclear Information System (INIS)

    Purpose: To assess whether online adaptive radiotherapy for bladder cancer is feasible across multiple Radiation Oncology departments using different imaging, delivery and recording technology. Materials and methods: A multi-centre feasibility study of online adaptive radiotherapy, using a choice of three “plan of the day”, was conducted at 12 departments. Patients with muscle-invasive bladder cancer were included. Departments were activated if part of the pilot study or after a site-credentialing visit. There was real time review of the first two cases from each department. Results: 54 patients were recruited, with 50 proceeding to radiotherapy. There were 43 males and 7 females with a mean age of 78 years. The tumour stages treated included T1 (1 patient), T2 (35), T3 (10) and T4 (4). One patient died of an unrelated cause during radiotherapy. The three adaptive plans were created before the 10th fraction in all cases. In 8 (16%) of the patients, a conventional plan using a ‘standard’ CTV to PTV margin of 1.5 cm was used for one or more fractions where the pre-treatment bladder CTV was larger than any of the three adaptive plans. The bladder CTV extended beyond the PTV on post treatment imaging in 9 (18%) of the 49 patients. Conclusions: From a technical perspective an online adaptive radiotherapy technique can be instituted in a multi-centre setting. However, without further bladder filling control or imaging, a CTV to PTV margin of 7 mm is insufficient

  6. Long-term outcomes of dynamic conformal arc irradiation combined with neoadjuvant hormonal therapy in Japanese patients with T1c-T2N0M0 prostate cancer. Case series study

    International Nuclear Information System (INIS)

    There are few reports of the outcomes of external beam radiotherapy in Asian males with localized prostate cancer. The aim of this study is to evaluate the long-term outcomes of external beam irradiation using three-dimensional two-dynamic conformal arc therapy, combined with neoadjuvant hormonal therapy, in patients with T1c-T2N0M0 prostate cancer. Between March 2003 and August 2007, 150 Japanese patients with T1c-T2N0M0 prostate cancer were definitively treated with three-dimensional two-dynamic conformal arc therapy. The median age, pretreatment prostate-specific antigen values and neoadjuvant hormonal therapy period were 73 years, 9.4 ng/ml and 6 months, respectively. In principle, 74 Gy was delivered to the planning target volume, although the total dose was reduced to 70 Gy in patients with unfavorable risk factors, such as severe diabetes mellitus or anticoagulant therapy. No adjuvant hormonal therapy was given to any patient. Salvage hormonal therapy was started when the prostate-specific antigen value exceeded 4 ng/ml in a monotonically increasing manner. The median follow-up period was 79 months. Salvage hormonal therapy was initiated in 10 patients and the median prostate-specific antigen value at the initiation was 4.7 ng/ml. The 5-year Kaplan-Meier estimates of the biochemical relapse-free survival rate, the salvage hormonal therapy -free rate and the overall survival rate were 83.3% (95% confidence interval=77.1-89.6%), 94.3% (95% confidence interval=90.4-98.1%) and 96.3% (95% confidence interval=93.1-99.5%), respectively. The 5-year cumulative incidence rates of developing more than Grade 2 late rectal and urinary toxicities were 5.5 and 2.9%, respectively. Three-dimensional two-dynamic conformal arc therapy, with up to 74 Gy, in patients with T1c-T2N0M0 prostate cancer with neoadjuvant hormonal therapy was well tolerated and achieved good biochemical control and survival outcomes.

    International Nuclear Information System (INIS)

    Objective: To study the cosmetic outcome and curative effect of 6 MV X-ray tangential field radiotherapy for early stage breast cancer after conservative surgery. Methods: The eligible criteria were single tumor ≤3 cm in diameter, surgical margin negative and lymph node negative. The exclusive criteria were inflammatory carcinoma or male breast cancer. After conservative surgery, 42 patients with stage 0, I or II breast cancer were treated with conventional radiotherapy with a total dose of 50 Gy to the whole breast and 10 Gy boost to the tumor bed. The efficacy and the cosmetic outcome of radiotherapy were evaluated every 3 months for the first 2 years and every 6 months after that and every 12 months after 5 years. Results: The follow up time was 19-90 months (median 56 months). Two patients died of metastasis after 16 months and 36 months, which was diagnosed by CT scan. Excellent or good cosmetic outcome was > 93% at 36 months. The local control rate was 100%. The 1- and 3-year survival rates was 100% and 98%, respectively. Conclusions: Tangential field radiotherapy for early breast cancer after conservative surgery has a satisfied result in both tumor control and cosmetic outcome, which can definitely improve the life quality of the patients.

    The incidence and mortality of gastric cancer have been steadily decreased over the past few decades. However, gastric cancer is still one of the leading causes of cancer deaths across many regions of the world, particularly in Asian countries. In previous studies, nutrition has been considered one of significant risk factors in gastric cancer patients. Especially, malnourished patients are at greater risk of adverse clinical outcomes (e.g., longer hospital stay) and higher incidence of complications (e.g., wound/infectious complications) compared to well-nourished patients. Malnutrition is commonly found in advanced gastric cancer patients due to poor absorption of essential nutrients after surgery. Therefore, nutritional support protocols, such as early oral and enternal feeding, have been proposed in many studies, to improve unfavorable clinical outcomes and to reduce complications due to delayed application of oral nutritional support or parental feeding. Also, the supplied with enternal immune-enriched diet had more benefits in improving clinical outcomes and fewer complications compared to a group supplied with control formula. Using nutritional screening tools, such as nutritional risk index (NRI) and nutritional risk screening (NRS 2002), malnourished patients showed higher incidence of complications and lower survival rates than non-malnourished patients. However, a long-term nutritional intervention, such as nutritional counseling, was not effective in the patients. Therefore, early assessment of nutritional status in patients using a proper nutritional screening tool is suggested to prevent malnutrition and adverse health outcomes. Further studies with numerous ethnic groups may provide stronger scientific evidences in association between nutritional care and recovery from surgery in patients with gastric cancer. PMID:27152296

    2013-09-01

    Full Text Available Background: Pain and psychological distress frequently co-exist in cancer patients. Pain acceptance has been associated with improved physical and psychosocial well-being in chronic non-malignant pain patients, however its effects are unclear in cancer outpatients with pain. Methods: The sample consisted of 116 outpatients recruited from a tertiary oncology centre, with various types of cancer and pain levels. To assess patients, we used the Brief Pain Inventory, the Hospital Anxiety and Depression Scale and the Chronic Pain Acceptance Questionnaire comprising of: Activity engagement and Pain willingness. The extent to which acceptance predicts physical and psychological outcomes was investigated using multiple regression analyses. Results: Adjusting for patient characteristics and outcomes, activity engagement and pain willingness significantly predicted pain interference with function (p=.033 and p=.041 respectively. However, only the activity engagement predicted anxiety (p=.001 and depression (p<.001. Conclusion: Components of pain acceptance predicted patient functional outcomes. Activity engagement in particular, shows promise in predicting psychological well-being. Further studies could confirm its role in reducing anxiety and depression in cancer patients with pain, and whether it should be included in cancer pain management interventions.

    Markus Ringnér

    Full Text Available Microarray-based gene expression analysis holds promise of improving prognostication and treatment decisions for breast cancer patients. However, the heterogeneity of breast cancer emphasizes the need for validation of prognostic gene signatures in larger sample sets stratified into relevant subgroups. Here, we describe a multifunctional user-friendly online tool, GOBO (http://co.bmc.lu.se/gobo, allowing a range of different analyses to be performed in an 1881-sample breast tumor data set, and a 51-sample breast cancer cell line set, both generated on Affymetrix U133A microarrays. GOBO supports a wide range of applications including: 1 rapid assessment of gene expression levels in subgroups of breast tumors and cell lines, 2 identification of co-expressed genes for creation of potential metagenes, 3 association with outcome for gene expression levels of single genes, sets of genes, or gene signatures in multiple subgroups of the 1881-sample breast cancer data set. The design and implementation of GOBO facilitate easy incorporation of additional query functions and applications, as well as additional data sets irrespective of tumor type and array platform.

    Diabetes is a risk factor for colorectal cancer and several reports suggest worse cancer-specific outcomes in diabetes patients. Recent studies in multiple tumour types indicate metformin may positively impact on cancer-specific and overall survival. A population-based series of stage II colorectal cancer patients treated and followed from 2000 to 2013 were analysed for baseline characteristics, treatment, and outcomes. 1116 patients with stage II colon cancer were identified, 55.5% were male and median age was 70.9 years (range 20.5–101.2). The diabetes patients (21.6%, n = 241) were older than nondiabetes patients (median 74.0 versus 69.6, p = 0.0001). There was no impact of diabetes on cancer presentation or pathology. Diabetes patients were less likely to receive adjuvant treatment (13.7 versus 24.8%, p = 0.002) but were equally likely to complete treatment (69.7 versus 67.7%, p = 1.00). Diabetes did not significantly impact cancer recurrence (HR = 1.07, 95% CI 0.71–1.63) or overall survival (HR = 1.23, 95% CI 0.88–1.72), adjusted for age. Diabetes medication did not impact cancer recurrence or survival. Cancer presentation and outcomes in diabetes patients are comparable to those of nondiabetes patients in those with stage II colon cancer. The effect of metformin merits further evaluation in patients with colon cancer. PMID:26074965

  18. Genomic Copy Number Variations in the Genomes of Leukocytes Predict Prostate Cancer Clinical Outcomes.

    Yan P Yu

    Full Text Available Accurate prediction of prostate cancer clinical courses remains elusive. In this study, we performed whole genome copy number analysis on leukocytes of 273 prostate cancer patients using Affymetrix SNP6.0 chip. Copy number variations (CNV were found across all chromosomes of the human genome. An average of 152 CNV fragments per genome was identified in the leukocytes from prostate cancer patients. The size distributions of CNV in the genome of leukocytes were highly correlative with prostate cancer aggressiveness. A prostate cancer outcome prediction model was developed based on large size ratio of CNV from the leukocyte genomes. This prediction model generated an average prediction rate of 75.2%, with sensitivity of 77.3% and specificity of 69.0% for prostate cancer recurrence. When combined with Nomogram and the status of fusion transcripts, the average prediction rate was improved to 82.5% with sensitivity of 84.8% and specificity of 78.2%. In addition, the leukocyte prediction model was 62.6% accurate in predicting short prostate specific antigen doubling time. When combined with Gleason's grade, Nomogram and the status of fusion transcripts, the prediction model generated a correct prediction rate of 77.5% with 73.7% sensitivity and 80.1% specificity. To our knowledge, this is the first study showing that CNVs in leukocyte genomes are predictive of clinical outcomes of a human malignancy.

  19. Lung and colorectal cancer treatment and outcomes in the Veterans Affairs health care system

    International Nuclear Information System (INIS)

    Lung cancer (LC) and colorectal cancer (CRC) are the second- and third-most commonly diagnosed cancers in the Veterans Affairs (VA) health care system. While many studies have evaluated the treatment quality and outcomes of various aspects of VA LC and CRC care, there are no known reviews synthesizing this information across studies. The purpose of this literature review was to describe LC and CRC treatment (ie, surgical and nonsurgical) and outcomes (eg, mortality, psychosocial, and other) in the VA health care system as reported in the existing peer-reviewed scientific literature. We identified potential articles through a search of published literature using the PubMed electronic database. Our search strategy identified articles containing Medical Subject Headings terms and keywords addressing veterans or veterans’ health and LC and/or CRC. We limited articles to those published in the previous 11 years (January 1, 2003 through December 31, 2013). A total of 230 articles were retrieved through the search. After applying the selection criteria, we included 74 studies (34 LC, 47 CRC, and seven both LC and CRC). VA provides a full array of treatments, often with better outcomes than other health care systems. More work is needed to assess patient-reported outcomes

  20. Patient outcomes of monotherapy with hypofractionated three-dimensional conformal radiation therapy for stage T2 or T3 non-small cell lung cancer: a retrospective study

    International Nuclear Information System (INIS)

    Hypofractionated three-dimensional conformal radiation therapy (3D-CRT) is a treatment option for patients with early-stage non-small cell lung cancer (NSCLC) who are medically unable to tolerate surgery and who are not amenable to treatment with stereotactic body radiotherapy. This study assessed the efficacy and safety of 3D-CRT as a monotherapy in patients with localized stage T2 or T3 NSCLC. This retrospective study consisted of 29 patients (20 males) aged 56–89 years (median, 76 years) with histologically confirmed NSCLC who underwent 3D-CRT between 2005 and 2014. The median duration of patient observation was 17.0 months (range, 1.0–64.0 months). Complete and partial responses occurred in 13.8 and 44.8 % of patients, respectively, and the overall response rate was 58.2 %. Meanwhile, the 1- and 3-year survival rates were 65.8 and 33.8 %, respectively. In T2 NSCLC, the median survival time (MST) was 12 months, and the 1- and 3-year survival rates were 62.4 and 21.4 %, respectively. In T3 NSCLC, the MST was 17 months, and the 1- and 3-year survival rates were 72.9 and 48.6 %, respectively. Severe toxicities (Common Terminology Criteria Grade 3) were not observed. The mean biologically effective dose required to improve local control exceeded 80 Gy (range, 67.2–96.0 Gy). These findings support a role for 3D-CRT as a treatment option for patients who refuse or could not tolerate surgical therapy with early-stage NSCLC. Although this was a small, retrospective study, it may form the basis for future, larger controlled studies on 3D-CRT as a monotherapy for NSCLC

    Many studies have reported that adherence to health promotion guidelines for diet, physical activity, and maintenance of healthy body weight may decrease cancer incidence and mortality. A systematic review was performed to examine associations between adherence to established cancer prevention guidelines for diet and physical activity and overall cancer incidence and mortality. PubMed, Google Scholar, and Cochrane Reviews databases were searched following the current recommendations of Preferred Reporting Items for Systematic Reviews and Meta-analysis Approach (PRISMA). Twelve studies met inclusion criteria for this review. High versus low adherence to established nutrition and physical activity cancer prevention guidelines was consistently and significantly associated with decreases of 10% to 61% in overall cancer incidence and mortality. Consistent significant reductions were also shown for breast cancer incidence (19%-60%), endometrial cancer incidence (23%-60%), and colorectal cancer incidence in both men and women (27%-52%). Findings for lung cancer incidence were equivocal, and no significant relationships were found between adherence and ovarian or prostate cancers. Adhering to cancer prevention guidelines for diet and physical activity is consistently associated with lower risks of overall cancer incidence and mortality, including for some site-specific cancers.

  5. Treatment outcomes of definitive chemoradiotherapy for patients with hypopharyngeal cancer

    International Nuclear Information System (INIS)

    We analyzed the efficacy of definitive chemoradiotherapy (CRT) for patients with hypopharyngeal cancer (HPC). Subjects comprised 97 patients who were treated with definitive CRT from 1990 to 2006. Sixty-one patients (62.9%) with resectable disease who aimed to preserve the larynx received induction chemotherapy (ICT), whereas 36 patients (37.1%) with resectable disease who refused an operation or who had unresectable disease received primary alternating CRT or concurrent CRT (non-ICT). The median dose to the primary lesion was 66 Gy. The median follow-up time was 77 months. The 5-year rates of overall survival (OS), progression-free survival (PFS), local control (LC), and laryngeal preservation were 68.7%, 57.5%, 79.1%, and 70.3%, respectively. The T-stage was a significant prognostic factor in terms of OS, PFS and LC in both univariate and multivariate analyses. The 5-year rates of PFS were 45.4% for the ICT group and 81.9% for the non-ICT group. The difference between these groups was significant with univariate analysis (P=0.006). Acute toxicity of Grade 3 to 4 was observed in 34 patients (35.1%). Grade 3 dysphagia occurred in 20 patients (20.6%). Twenty-nine (29.8%) of 44 patients with second primary cancer had esophageal cancer. Seventeen of 29 patients had manageable superficial esophageal cancer. The clinical efficacy of definitive CRT for HPC is thought to be promising in terms of not only organ preservation but also disease control. Second primary cancer may have a clinical impact on the outcome for HPC patients, and special care should be taken when screening at follow-up. (author)

  6. Does family history of prostate cancer affect outcomes following radiotherapy?

    International Nuclear Information System (INIS)

    Objective: To examine family history (FH) as a prognostic factor following radiotherapy (RT). Materials and methods: Between 1989 and 2007, 1711 men with clinically localized prostate cancer and complete family history who had received RT (median RT dose = 74 Gy) without androgen deprivation therapy were analyzed. FH was defined as any prostate cancer in a first degree relative. For the biochemical failure (BF) outcome, this sample size has 85% power to detect a hazard ratio of 1.56 for positive versus negative FH. Results: With a median follow-up of 71 months, there was no significant difference in the distribution of Gleason score (GS) or prostate specific antigen (PSA) based on FH. A positive FH was not an independent predictor of BF, distant metastasis (DM), prostate cancer specific mortality (PCSM), or overall mortality (OM) in Cox proportional multivariable analysis. On further analysis in a Cox proportional multivariable analysis, men with two or more first degree relatives with prostate cancer had a significantly higher likelihood of BF and DM than those with no FH, although there was no difference in PCSM or OM. Men with a positive FH (23%) were more likely to be younger, have a lower PSA, and non-palpable disease. There was no interaction between a positive FH and neither race nor treatment era (pre-PSA vs. PSA era). Conclusions: A positive FH is not a prognostic factor following RT and should not alter standard treatment recommendations. Patients with two or more first degree relatives with prostate cancer had a higher likelihood of BF and DM, but there was no effect on survival. There was no interaction between a positive FH and African American race or treatment era. A positive FH was however, associated with more favorable PSA values and T-stage that may be the result of earlier screening

  10. FDG PET during radiochemotherapy is predictive of outcome at 1 year in non-small-cell lung cancer patients: a prospective multicentre study (RTEP2)

    International Nuclear Information System (INIS)

    To assess prospectively the prognostic value of FDG PET/CT during curative-intent radiotherapy (RT) with or without concomitant chemotherapy in patients with non-small-cell lung cancer (NSCLC). Patients with histological proof of invasive localized NSCLC and evaluable tumour, and who were candidates for curative-intent radiochemotherapy (RCT) or RT were preincluded after providing written informed consent. Definitive inclusion was conditional upon significant FDG uptake before RT (PET1). All included patients had a FDG PET/CT scan during RT (PET2, mean dose 43 Gy) and were evaluated by FDG PET/CT at 3 months and 1 year after RT. The main endpoint was death (from whatever cause) or tumour progression at 1 year. Of 77 patients preincluded, 52 were evaluable. Among the evaluable patients, 77 % received RT with induction chemotherapy and 73 % RT with concomitant chemotherapy. At 1 year, 40 patients (77 %) had died or had tumour progression. No statistically significant association was found between stage (IIIB vs. other), histology (squamous cell carcinoma vs. other), induction or concomitant chemotherapy, and death/tumour progression at 1 year. The SUVmax in the PET2 scan was the single variable predictive of death or tumour progression at 1 year (odds ratio 1.97, 95 % CI 1.25 - 3.09, p = 0.003) in multivariate analysis. The area under the receiver operating characteristic curve was 0.85 (95 % CI 0.73 - 0.94, p -4). A SUVmax value of 5.3 in the PET2 scan yielded a sensitivity of 70 % and a specificity of 92 % for predicting tumour progression or death at 1 year. This prospective multicentre study demonstrated the prognostic value in terms of disease-free survival of SUVmax assessed during the 5th week of curative-intent RT or RCT in NSCLC patients (NCT01261598; RTEP2 study).

    Full Text Available Objective. A number of evidence-based guidelines for diagnosis and management of prostate cancer have been published. The aim of this study is to evaluate the adherence of Italian urologists to the guidelines concerning the preoperative imaging staging of prostate cancer. Methods. In October 2007 a multicentric observational perspective study called Multicentric Italian Report on Radical prostatectomy Outcome and Research (MIRROR was started in 135 Italian urology centers. Recruitment was closed in December 2008 and 2,408 cases were collected. In this paper we have taken into consideration all examinations carried out for preoperative imaging staging, evaluating compliance with the recommendations in the American Urological Association (AUA and European Association of Urology (EAU guidelines. Results. Five hundred sixty-seven (53.34% patients were not managed according to the EAU guidelines concerning T-staging, 545 (51.27% concerning N-staging and 757 (71.21% concerning M-staging. According to AUA guidelines, we also analyzed patients with a Gleason grade of biopsy specimens of 7: 238 (57.35% of these patients had undergone testing for T staging, 244 (57.35% for N-staging and 322 (77.60% for M-staging. Conclusions. The compliance of Italian urologists with the guidelines is low, leading to an inappropriate increase in cost of care and unnecessary anxiety for the patients.

  13. Toxicities Affecting Quality of Life After Chemo-IMRT of Oropharyngeal Cancer: Prospective Study of Patient-Reported, Observer-Rated, and Objective Outcomes

    International Nuclear Information System (INIS)

    Purpose: To test the hypothesis that intensity modulated radiation therapy (IMRT) aiming to spare the salivary glands and swallowing structures would reduce or eliminate the effects of xerostomia and dysphagia on quality of life (QOL). Methods and Materials: In this prospective, longitudinal study, 72 patients with stage III-IV oropharyngeal cancer were treated uniformly with definitive chemo-IMRT sparing the salivary glands and swallowing structures. Overall QOL was assessed by summary scores of the Head Neck QOL (HNQOL) and University of Washington QOL (UWQOL) questionnaires, as well as the HNQOL “Overall Bother” question. Quality of life, observer-rated toxicities (Common Toxicity Criteria Adverse Effects scale, version 2), and objective evaluations (videofluoroscopy assessing dysphagia and saliva flow rates assessing xerostomia) were recorded from before therapy through 2 years after therapy. Correlations between toxicities/objective evaluations and overall QOL were assessed using longitudinal repeated measures of analysis and Pearson correlations. Results: All observer-rated toxicities and QOL scores worsened 1-3 months after therapy and improved through 12 months, with minor further improvements through 24 months. At 12 months, dysphagia grades 0-1, 2, and 3, were observed in 95%, 4%, and 1% of patients, respectively. Using all posttherapy observations, observer-rated dysphagia was highly correlated with all overall QOL measures (P<.0001), whereas xerostomia and mucosal and voice toxicities were significantly correlated with some, but not all, overall QOL measures, with lower correlation coefficients than dysphagia. Late overall QOL (≥6 or ≥12 months after therapy) was primarily associated with observer-rated dysphagia, and to a lesser extent with xerostomia. Videofluoroscopy scores, but not salivary flows, were significantly correlated with some of the overall QOL measures. Conclusion: After chemo-IMRT, although late dysphagia was on average mild

  16. Radical radiotherapy for cervix cancer: The effect of waiting time on outcome

    International Nuclear Information System (INIS)

    Purpose: To assess the effect of treatment waiting time on clinical outcome for patients with cervix cancers treated with radical radiotherapy. Methods and materials: A retrospective analysis was conducted on all cervix cancer patients treated with radical radiotherapy between 1990 and 2001 at the Ottawa Regional Cancer Centre. Analyses were performed according to the three following separate definitions of waiting times: interval from start of radiotherapy to (1) date of initial biopsy (2) date of examination under anesthesia, and (3) date of radiation oncology consultation. Associations between waiting times and patient characteristics and disease control were investigated using t-tests, analyses of variance, and Cox regression analyses. Results: A total of 195 patients were studied. The vast majority of patients were treated within 5, 6, and 8 weeks of their consultation (91%), examination under anesthesia (88%), and biopsy (81%), respectively. On average, delays between initial biopsy and treatment start were greater for older patients (p = 0.025) (5.8 weeks for 70 years old) and those with smaller tumors (p 4 cm vs. 6.3 weeks for ≤4 cm). Univariate analysis revealed no adverse effect of treatment delay on tumor control. Multivariate analysis, with the inclusion of multiple prognostic tumor and treatment parameters, revealed an adverse effect of treatment delay on survival outcomes. Conclusions: Longer radiotherapy waiting times were found to be associated with diminished survival outcomes for patients treated radically for cervix cancer. The significance of this observed association requires further investigation

  18. Correlating tumor metabolic progression index measured by serial FDG PET-CT, apparent diffusion coefficient measured by magnetic resonance imaging (MRI) and blood genomics to patient’s outcome in advanced colorectal cancer: the CORIOLAN study

    International Nuclear Information System (INIS)

    Metastatic colorectal cancer (mCRC) may present various behaviours that define different courses of tumor evolution. There is presently no available tool designed to assess tumor aggressiveness, despite the fact that this is considered to have a major impact on patient outcome. CORIOLAN is a single-arm prospective interventional non-therapeutic study aiming mainly to assess the natural tumor metabolic progression index (TMPI) measured by serial FDG PET-CT without any intercurrent antitumor therapy as a prognostic factor for overall survival (OS) in patients with mCRC. Secondary objectives of the study aim to test the TMPI as a prognostic marker for progression-free survival (PFS), to assess the prognostic value of baseline tumor FDG uptake on PFS and OS, to compare TMPI to classical clinico-biological assessment of prognosis, and to test the prognostic value on OS and PFS of MRI-based apparent diffusion coefficient (ADC) and variation of vADC using voxel-based diffusion maps. Additionally, this study intends to identify genomic and epigenetic factors that correlate with progression of tumors and the OS of patients with mCRC. Consequently, this analysis will provide information about the signaling pathways that determine the natural and therapy-free course of the disease. Finally, it would be of great interest to investigate whether in a population of patients with mCRC, for which at present no known effective therapy is available, tumor aggressiveness is related to elevated levels of circulating tumor cells (CTCs) and to patient outcome. Tumor aggressiveness is one of the major determinants of patient outcome in advanced disease. Despite its importance, supported by findings reported in the literature of extreme outcomes for patients with mCRC treated with chemotherapy, no objective tool allows clinicians to base treatment decisions on this factor. The CORIOLAN study will characterize TMPI using FDG-PET-based metabolic imaging of patients with chemorefractory m

    2013-12-01

    Crossover designs are well known to have major advantages when comparing the effect of two treatments which do not interact. With a right-censored survival endpoint, however, this design is quickly abandoned in favour of the more costly parallel design. Motivated by human immunodeficiency virus (HIV) prevention studies which lacked power, we evaluate what may be gained in this setting and compare parallel with crossover designs. In a heterogeneous population, we find and explain a substantial increase in power for the crossover study using a non-parametric logrank test. With frailties in a proportional hazards model, crossover designs equally lead to substantially smaller variance for the subject-specific hazard ratio (HR), while the population-averaged HR sees negligible gain. Its efficiency benefit is recovered when the population-averaged HR is reconstructed from estimated subject-specific hazard rates. We derive the time point for treatment crossover that optimizes efficiency and end with the analysis of two recent HIV prevention trials. We find that a Cellulose sulphate trial could have hardly gained efficiency from a crossover design, while a Nonoxynol-9 trial stood to gain substantial power. We conclude that there is a role for effective crossover designs in important classes of survival problems. PMID:21715438

Currently, all available examination and detection methods cannot accurately predict the clinical outcome. Therefore, it is extremely important to identify novel molecular biomarkers for personalized medication and to significantly improve the overall outcome. The “noncoding RNAs” (ncRNAs are a group of RNAs that do not code for proteins, and they are categorized as structural RNAs and regulatory RNAs. It has been shown that microRNAs and long ncRNAs function as regulatory RNAs to affect the progression of various diseases. Many studies have confirmed a role for ncRNAs in the progression of PDAC during the last few years. Because of the significant role of ncRNAs in PDAC, ncRNA profiling may be used to predict PDAC outcome with high accuracy. This review comprehensively analyzes the value of ncRNAs as potential biomarkers to predict the outcome in PDAC and the possible mechanisms thereof.

  4. Carbonic anhydrase XII expression is associated with histologic grade of cervical cancer and superior radiotherapy outcome

    International Nuclear Information System (INIS)

    To investigate whether expression of carbonic anhydrase XII (CA12) is associated with histologic grade of the tumors and radiotherapy outcomes of the patients with invasive cervical cancer. CA12 expression was examined by immunohistochemical stains in cervical cancer tissues from 183 radiotherapy patients. Histological grading was classified as well (WD), moderately (MD) or poorly differentiated (PD). Oligonucleotide microarray experiment was performed using seven cervical cancer samples to examine differentially expressed genes between WD and PD cervical cancers. The association between CA12 and histological grade was analyzed by chi-square test. CA12 and histological grades were analyzed individually and as combined CA12 and histologic grade categories for effects on survival outcome. Immunohistochemical expression of CA12 was highly associated with the histologic grade of cervical cancer. Lack of CA12 expression was associated with PD histology, with an odds ratio of 3.9 (P = 0.01). Microarray analysis showed a fourfold reduction in CA12 gene expression in PD tumors. CA12 expression was marginally associated with superior disease-free survival. Application of the new combined categories resulted in further discrimination of the prognosis of patients with moderate and poorly differentiated tumor grade. Our study indicates that CA12 may be used as a novel prognostic marker in combination with histologic grade of the tumors

    Full Text Available Abstract Background To investigate whether expression of carbonic anhydrase XII (CA12 is associated with histologic grade of the tumors and radiotherapy outcomes of the patients with invasive cervical cancer. Methods CA12 expression was examined by immunohistochemical stains in cervical cancer tissues from 183 radiotherapy patients. Histological grading was classified as well (WD, moderately (MD or poorly differentiated (PD. Oligonucleotide microarray experiment was performed using seven cervical cancer samples to examine differentially expressed genes between WD and PD cervical cancers. The association between CA12 and histological grade was analyzed by chi-square test. CA12 and histological grades were analyzed individually and as combined CA12 and histologic grade categories for effects on survival outcome. Results Immunohistochemical expression of CA12 was highly associated with the histologic grade of cervical cancer. Lack of CA12 expression was associated with PD histology, with an odds ratio of 3.9 (P = 0.01. Microarray analysis showed a fourfold reduction in CA12 gene expression in PD tumors. CA12 expression was marginally associated with superior disease-free survival. Application of the new combined categories resulted in further discrimination of the prognosis of patients with moderate and poorly differentiated tumor grade. Conclusions Our study indicates that CA12 may be used as a novel prognostic marker in combination with histologic grade of the tumors.

    Full Text Available Abstract Background This study systematically reviewed the evidence on the influence of stigma and nihilism on lung cancer patterns of care; patients’ psychosocial and quality of life (QOL outcomes; and how this may link to public health programs. Methods Medline, EMBASE, ProQuest, CINAHL, PsycINFO databases were searched. Inclusion criteria were: included lung cancer patients and/or partners or caregivers and/or health professionals (either at least 80% of participants had lung cancer or were partners or caregivers of lung cancer patients, or there was a lung cancer specific sub-group focus or analysis, assessed stigma or nihilism with respect to lung cancer and published in English between 1st January 1999 and 31st January 2011. Trial quality and levels of evidence were assessed. Results Eighteen articles describing 15 studies met inclusion criteria. The seven qualitative studies were high quality with regard to data collection, analysis and reporting; however most lacked a clear theoretical framework; did not address interviewer bias; or provide a rationale for sample size. The eight quantitative studies were generally of low quality with highly selected samples, non-comparable groups and low participation rates and employed divergent theoretical and measurement approaches. Stigma about lung cancer was reported by patients and health professionals and was related to poorer QOL and higher psychological distress in patients. Clear empirical explorations of nihilism were not evident. There is qualitative evidence that from the patients’ perspectives public health programs contribute to stigma about lung cancer and this was supported by published commentary. Conclusions Health-related stigma presents as a part of the lung cancer experience however there are clear limitations in the research to date. Future longitudinal and multi-level research is needed and this should be more clearly linked to relevant theory.

  7. Laryngeal and hypopharyngeal cancer requiring tracheotomy for radiotherapy and chemoradiotherapy. Outcome and closure of tracheal stoma

    International Nuclear Information System (INIS)

    We studied the outcome of laryngeal and hypopharyngeal cancers requiring tracheotomy for radiotherapy and chemoradiotherapy, focusing on the rate of larynx preservation, the closure rate of the tracheal stoma, and clinical factors relating to successful closure of the tracheal stoma after treatment. The subjects were 13 cases, consisting of 4 cases of laryngeal cancer and 9 cases of hypopharyngeal cancer. They required tracheotomy for radical chemoradiotherapy or radiotherapy between 2003 and 2008 at Iwaki Kyoritsu General Hospital. The overall survival rate was 38% (5/13), and only 11% (1/9) for hypopharyngeal cancer. Although the rate of larynx preservation was 69% (9/13), the closure rate of the tracheal stoma was 23% (3/13) for all 13 cases, and 40% (2/5) for the five final surviving patients. The cause of failure to close the tracheal stoma was mainly death by original cancer, and stenosis of the upper airway by prolonged laryngeal edema in the survival cases. Regarding pre-operative factors affecting stoma closure, there was a correlation between T2 cases and no vocal cord paralysis cases, although no significant difference was observed. The outcome of laryngeal or hypopharyngeal cancer requiring tracheotomy for radiotherapy and chemoradiotherapy was poor, and the possibility of closing a tracheal stoma was low even when the patient received local disease control and survived. To maintain a good relationship after treatment with patients and their families who hope for larynx preservation and choose radiotherapy, it is important to explain the circumstances relating to outcome and closure of tracheal stoma before they receive treatment.

  8. Minimal preparation computed tomography instead of barium enema/colonoscopy for suspected colon cancer in frail elderly patients: an outcome analysis study

    International Nuclear Information System (INIS)

    AIM: To evaluate the efficacy of minimal preparation computed tomography (MPCT) in diagnosing clinically significant colonic tumours in frail, elderly patients. MATERIALS AND METHODS: A prospective study was performed in a group of consecutively referred, frail, elderly patients with symptoms or signs of anaemia, pain, rectal bleeding or weight loss. The MPCT protocol consisted of 1.5 l Gastrografin 1% diluted with sterile water administered during the 48 h before the procedure with no bowel preparation or administration of intravenous contrast medium. Eight millimetre contiguous scans through the abdomen and pelvis were performed. The scans were double-reported by two gastrointestinal radiologists as showing definite (>90% certain), probable (50-90% certain), possible (<50% certain) neoplasm or normal. Where observers disagreed the more pessimistic of the two reports was accepted. The gold standard was clinical outcome at 1 year with positive end-points defined as (1) histological confirmation of CRC, (2) clinical presentation consistent with CRC without histological confirmation if the patient was too unwell for biopsy/surgery, and (3) death directly attributable to colorectal carcinoma (CRC) with/without post-mortem confirmation. Negative end-points were defined as patients with no clinical, radiological or post-mortem findings of CRC. Patients were followed for 1 year or until one of the above end-points were met. RESULTS: Seventy-two patients were included (mean age 81; range 62-93). One-year follow-up was completed in 94.4% (n=68). Mortality from all causes was 33% (n=24). Five histologically proven tumours were diagnosed with CT and there were two probable false-negatives. Results were analysed twice: assuming all CT lesions test positive and considering 'possible' lesions test negative [brackets] (95% confidence intervals): sensitivity 0.88 (0.47-1.0) [0.75 (0.35-0.97)], specificity 0.47 (0.34-0.6) [0.87 (0.75-0.94)], positive predictive value 0.18 [0

    2016-06-01

    Risks of non-cancer outcomes after exposure to atomic bomb (A-bomb) radiation have been evaluated among the Life Span Study (LSS) cohort and its subcohort, the Adult Health Study (AHS). Information regarding non-cancer outcomes in the LSS is obtained from death certificates. In the AHS, members undergo clinical examinations biennially to determine their health status. Many AHS studies have been limited to participants attending the clinic over a limited period, and therefore have varying degrees of inferential utility; as such, care is required for comparison with the LSS results. Disease structure of non-cancer diseases in Japan has changed over the long follow-up period since the end of World War II. The health status of the A-bomb survivors may be associated with the hardships of living in a devastated city and impoverished country following the prolonged war effort, in addition to the direct effects of radiation exposure. Radiation-related risk of cardiovascular disease may have increased due to radiation-related increased risk of hypertension and other secondary associations, and the risk of atherosclerotic disorders has also been reported recently. These results should be interpreted with caution because of changes in disease definitions over the follow-up period. The radiation-related risk of non-cancer respiratory diseases also appears to have increased over the follow-up period, but the shapes of the dose-response curves have shown little consistency.

    Full Text Available Abstract Background The immune response has been proposed to be an important factor in determining patient outcome in colorectal cancer (CRC. Previous studies have concentrated on characterizing T cell populations in the primary tumour where T cells with regulatory effect (Foxp3+ Tregs have been identified as both enhancing and diminishing anti-tumour immune responses. No previous studies have characterized the T cell response in the regional lymph nodes in CRC. Methods Immunohistochemistry was used to analyse CD4, CD8 or Foxp3+ T cell populations in the regional lymph nodes of patients with stage II CRC (n = 31, with (n = 13 or without (n = 18 cancer recurrence after 5 years of follow up, to determine if the priming environment for anti-tumour immunity was associated with clinical outcome. Results The proportions of CD4, CD8 or Foxp3+ cells in the lymph nodes varied widely between and within patients, and there was no association between T cell populations and cancer recurrence or other clinicopathological characteristics. Conclusions These data indicate that frequency of these T cell subsets in lymph nodes may not be a useful tool for predicting patient outcome.

    Full Text Available Abstract Background Changes in DNA methylation of crucial cancer genes including tumor suppressors can occur early in carcinogenesis, being potentially important early indicators of cancer. The objective of this study was to examine a multiplexed approach to assess the methylation of tumor suppressor genes as tumor stratification and clinical outcome prognostic biomarkers for lung cancer. Methods A multicandidate probe panel interrogated DNA for aberrant methylation status in 18 tumor suppressor genes in lung cancer using a methylation-specific multiplex ligation-dependent probe amplification assay (MS-MLPA. Lung cancer cell lines (n = 7, and primary lung tumors (n = 54 were examined using MS-MLPA. Results Genes frequently methylated in lung cancer cell lines including SCGB3A1, ID4, CCND2 were found among the most commonly methylated in the lung tumors analyzed. HLTF, BNIP3, H2AFX, CACNA1G, TGIF, ID4 and CACNA1A were identified as novel tumor suppressor candidates methylated in lung tumors. The most frequently methylated genes in lung tumors were SCGB3A1 and DLC1 (both 50.0%. Methylation rates for ID4, DCL1, BNIP3, H2AFX, CACNA1G and TIMP3 were significantly different between squamous and adenocarcinomas. Methylation of RUNX3, SCGB3A1, SFRP4, and DLC1 was significantly associated with the extent of the disease when comparing localized versus metastatic tumors. Moreover, methylation of HTLF, SFRP5 and TIMP3 were significantly associated with overall survival. Conclusions MS-MLPA can be used for classification of certain types of lung tumors and clinical outcome prediction. This latter is clinically relevant by offering an adjunct strategy for the clinical management of lung cancer patients.

    Background Recently, we reported the identification of a previously uncharacterized and evolutionarily conserved gene, fragile-site associated tumor suppressor (FATS), at a frequently deleted region in irradiation (IR)-induced tumors.However, the role of FATS in breast cancer development and its clinical significance has not been defined. The aim of this study was to determine the role of FA7S in breast cancer development and to evaluate its clinical significance in breast cancer.Methods The expression level of FATS mRNA was determined in 106 breast carcinomas and 23 paired normal breast tissues using quantitative real time reverse transcription-polymerase chain reaction (RT-PCR). The relationship between FATS expression and clinicopathological parameters were also analyzed.Results The mRNA level of FATS was down-regulated in breast cancer compared with paired normal tissues. Low expression of FATS was correlated with high nuclear grade. There was a tendency to a favorable outcome for patients with high expression of FATS (P=0.346). However, low expression of FATS was associated with poor outcome of breast cancer patients with node positive (P=0.011). Furthermore, the mRNA level of FATS showed an independent value in predicting the outcome of breast cancer patients with positive lymph nodes.Conclusion FATS is involved in the carcinogenesis and development of breast cancer and could be a potential biomarker and prognostic factor for breast cancer therapy.

    2011-01-01

    Recently, several classifiers that combine primary tumor data, like gene expression data, and secondary data sources, such as protein-protein interaction networks, have been proposed for predicting outcome in breast cancer. In these approaches, new composite features are typically constructed by aggregating the expression levels of several genes. The secondary data sources are employed to guide this aggregation. Although many studies claim that these approaches improve classification performance over single gene classifiers, the gain in performance is difficult to assess. This stems mainly from the fact that different breast cancer data sets and validation procedures are employed to assess the performance. Here we address these issues by employing a large cohort of six breast cancer data sets as benchmark set and by performing an unbiased evaluation of the classification accuracies of the different approaches. Contrary to previous claims, we find that composite feature classifiers do not outperform simple sin...

    Endoscopic treatment, such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), has been established as one of the treatment options for selected cases with early gastric cancer (EGC). Most studies on this topic have been carried out by researchers in Japan. Recently, the experience in EMR/ESD for EGC outside Japan is increasingly reported. In Korea, gastric cancer is the most common malignant disease, and the second leading cause of cancer death. Currently, EMR for EGC is widely performed in many centers in Korea. Early results with a short-term follow-up period are very promising in Korea. The complete resection rate of EMR was 37.8%-94.3%, and that of ESD was 77.4%-93.1%. In this review, we will provide an overview of the outcomes of endoscopic treatments in Korea.

    According to the European Association of Urology (EAU) guidelines,a life expectancy of>10 years is considered an important factor in the treatment of prostate cancer.The Charlson score is used to predict mortality based on comorbidities.The purpose of this study was to investigate the relationship between age,Charlson score and outcome in patients with cT3a prostate cancer.Between 1987 and 2004,200 patients,who were with clinical T3a prostate cancer and who underwent radical prostatectomy (RP),were previously detected by digital rectal examination (DRE).Patients were categorized into two age groups (<65 and≥65 years old).Patients were also divided into two groups according to Charlson score (=0 and≥1).Both age and Charlson score were analyzed regarding their predictive power of patients' outcomes.The mean follow-up period was 70.6 months,and the mean age of patients was 63.3 years.In all,106 patients were<65 years old and 94 patients were≥65 years old.Age was a significant predictor of overall survival (OS).A Charlson score of O was found in 110 patients,and of≥1 in 90 patients.Charlson score was not a significant predictor of biochemical progression-free survival (BPFS),clinical progression-free survival (CPFS) or OS.Cox multivariate analysis showed that margin status was a significant independent factor in BPFS,and cancer volume was a significant independent factor in CPFS.Charlson score does not influence the outcome in patients with clinical locally advanced prostate cancer.Age may influence OS.RP can be performed in motivated healthy older patients.However,the patients need to be counseled regarding possible surgery-related side effects,such as urinary incontinence and erectile dysfunction,which are age-and comorbidity-dependent.

    This retrospective study investigated the clinical characteristics and outcomes of second malignant neoplasms (SMNs) in survivors of childhood cancer from multiple institutions in Korea. A total of 102 patients from 11 institutions who developed SMN after childhood cancer treatment between 1998 and 2011 were retrospectively enrolled. The most common primary malignant neoplasms (PMNs) were central nervous system (CNS) tumors (n = 17), followed by acute lymphoblastic leukemia (n = 16), non-Hodgkin lymphoma (n = 13), and osteosarcoma (n = 12). The most common SMNs were therapy-related myeloid neoplasms (t-MNs; acute myeloid leukemia [AML], 29 cases; myelodysplastic syndrome [MDS], 12 cases), followed by thyroid carcinomas (n = 15) and CNS tumors (n = 10). The median latency period was 4.9 years (range, 0.5-18.5 years). Among 45 patients with solid tumors defined as an SMN, 15 (33%) developed the lesion in a field previously subjected to radiation. The 5-year overall survival (OS) rate of patients with an SMN was 45% with a median follow-up time of 8.6 years. Patients with AML, MDS, and CNS tumors exhibited the poorest outcomes with 5-year OS rates of 18%, 33%, and 32%, respectively, whereas those with second osteosarcoma showed comparable outcomes (64%) to patients with primary counterpart and those with second thyroid carcinoma had a 100% OS rate. Further therapeutic efforts are recommended to improve the survival outcomes in patients with SMNs, especially in cases with t-MNs and CNS tumors. PMID:27478336

    This study was undertaken to reveal the trends of prostate cancer and the outcome of treatment modalities for each disease stage in patients in a single institute over a 10-year period. From January 1994 through December 2003, 420 consecutive patients with previously untreated and histologically confirmed prostate cancer were analyzed for annual distributions of disease stages and treatment modalities and for long-term clinical progression-free survival, prostate cancer-specific survival, and prostate-specific antigen (PSA failure-free survival rates for each stage and treatment modality. Annual trends showed that the number of patients, especially those with clinically localized cancer, increased dramatically. The 5-year disease-specific survival rates for patients with clinically localized disease were 100 percent for all treatment modalities, including hormonal therapy alone. Patients with PSA levels less than 10 ng/ml showed an 81 percent 5-year PSA failure-free survival rate with radical prostatectomy. Stage C patients treated by surgery or radiation-based therapy with concomitant hormonal therapy obtained 93 percent and 100 percent cause-specific survival rates, respectively, and those treated by hormonal therapy alone showed a 79 percent rate. The number of patients with localized prostate cancer was increasing in this decade. While long-term hormonal therapy alone was highly efficient in controlling localized prostate cancer, radical therapies in conjunction with neo-adjuvant hormonal therapy produced better survival rates in cases of locally advanced disease.

    Background and purpose: to determine whether the blood hemoglobin concentration correlates with the prognosis of patients with early breast cancer and, if so, whether this is restricted to treatment modality. Patients and methods: data were collected retrospectively from patients with early breast cancer (T1,2 NO-2 MO) who underwent either breast-conserving surgery followed by adjuvant radiotherapy (BCS-RT; n = 96) or a modified radical mastectomy (MRM; n = 194). The effect of preoperative blood hemoglobin level, nodal status, histological grading and hormone receptor status on disease-free survival was determined for both treatment modalities using a cox regression model and visualized by kaplan-meier plots. Results: the blood hemoglobin concentration significantly correlated with disease-free survival of patients receiving BCS-RT (relative risk [RR]: 0.67 per g/dl; p = 0.007). This was independent of other known risk factors for breast cancer patients, as determined by multivariate analysis. By contrast, the blood hemoglobin level had no prognostic significance when patients were treated with MRM. Conclusion: blood hemoglobin concentration seems to affect the prognosis of patients with early breast cancer when a treatment schedule that includes radiotherapy is applied. Reduced radiosensitivity due to diminished tumor oxygenation may be the underlying cause. Confirmative trials and studies intended to elucidate the underlying mechanism are warranted. (orig.)

    Malnutrition is a significant factor in predicting cancer patients' quality of life (QoL). We systematically reviewed the literature on the role of nutritional status in predicting QoL in cancer. We searched MEDLINE database using the terms "nutritional status" in combination with "quality of life" together with "cancer". Human studies published in English, having nutritional status as one of the predictor variables, and QoL as one of the outcome measures were included. Of the 26 included studies, 6 investigated head and neck cancer, 8 gastrointestinal, 1 lung, 1 gynecologic and 10 heterogeneous cancers. 24 studies concluded that better nutritional status was associated with better QoL, 1 study showed that better nutritional status was associated with better QoL only in high-risk patients, while 1 study concluded that there was no association between nutritional status and QoL. Nutritional status is a strong predictor of QoL in cancer patients. We recommend that more providers implement the American Society of Parenteral and Enteral Nutrition (ASPEN) guidelines for oncology patients, which includes nutritional screening, nutritional assessment and intervention as appropriate. Correcting malnutrition may improve QoL in cancer patients, an important outcome of interest to cancer patients, their caregivers, and families. PMID:22531478

    Introduction Patients with metastatic colorectal cancer can develop jaundice from intrahepatic or extrahepatic causes. Currently, there is little data on the underlying causes and overall survival after onset of jaundice. The purpose of this study was to characterize the causes of jaundice and determine outcomes. Methods Six hundred twenty-nine patients treated for metastatic colorectal cancer between 2004 and 2010 were retrospectively reviewed. Those developing jaundice were grouped as having intrahepatic or extrahepatic obstruction. Demographics, clinicopathologic, and outcome data were analyzed. Results Sixty-two patients with metastatic colorectal cancer developed jaundice. Intrahepatic biliary obstruction was most common, occurring in younger patients. Time from metastatic diagnosis to presentation of jaundice was similar between groups, as was the mean number of prior lines of chemotherapy. Biliary decompression was successful 41.7 % of the time and was attempted more commonly for extrahepatic causes. Median overall survival after onset of jaundice was 1.5 months and it was similar between groups, but improved to 9.6 months in patients who were able to receive further chemotherapy. Conclusions Jaundice due to metastatic colorectal cancer is an ominous finding, representing aggressive tumor biology or exhaustion of therapies. Biliary decompression is often difficult and should only be pursued when additional treatment options are available. PMID:25300799

    The state of the literature on the psychosocial adjustment of children and adolescents with cancer is primed for novel contributions to the promotion of quality of life and depletion of negative psychosocial outcomes. Many recent studies indicate that this population may be at increased risk for depressed and anxious symptomatology; however, there is a large degree of individual variation. Coping responses have been demonstrated as significant predictors of adjustment outcomes with these pa...

    Full Text Available BACKGROUND: There exist significant challenges to the receipt of comprehensive oncologic treatment for children diagnosed with cancer in sub-Saharan Africa. To better define those challenges, we investigated treatment outcomes and risk factors for treatment abandonment in a cohort of children diagnosed with cancer at the University Teaching Hospital (UTH, the site of the only pediatric oncology ward in Zambia. METHODS: Using an established database, a retrospective cohort study was conducted of children aged 0-15 years admitted to the pediatric oncology ward between July 2008 and June 2010 with suspected cancer. Diagnosis, mode of diagnosis, treatment outcome, and risk factors for abandonment of treatment were abstracted from this database and clinical medical records. RESULTS: Among 162 children treated at the UTH during the study time period that met inclusion criteria, only 8.0% completed a treatment regimen with most of the patients dying during treatment or abandoning care. In multivariable analysis, shorter distance from home to the UTH was associated with a lower risk of treatment abandonment (Adjusted Odds Ratio [aOR]  = 0.48 (95% confidence interval [CI] 0.23-0.97. Conversely maternal education less than secondary school was associated with increased risk for abandonment (aOR = 1.65; 95% CI 1.05-2.58. CONCLUSIONS: Despite availability of dedicated pediatric oncology treatment, treatment completion rates are poor, due in part to the logistical challenges faced by families, low educational status, and significant distance from the hospital. Alternative treatment delivery strategies are required to bring effective pediatric oncology care to the patients in need, as their ability to come to and remain at a central tertiary care facility for treatment is limited. We suggest that the extensive system now in place in most of sub-Saharan Africa that sustains life-long antiretroviral therapy for children with human immunodeficiency virus (HIV

  10. Gene Expression Profiling to Predict Outcome After Chemoradiation in Head and Neck Cancer

    International Nuclear Information System (INIS)

    Purpose: The goal of the present study was to improve prediction of outcome after chemoradiation in advanced head and neck cancer using gene expression analysis. Materials and Methods: We collected 92 biopsies from untreated head and neck cancer patients subsequently given cisplatin-based chemoradiation (RADPLAT) for advanced squamous cell carcinomas (HNSCC). After RNA extraction and labeling, we performed dye swap experiments using 35k oligo-microarrays. Supervised analyses were performed to create classifiers to predict locoregional control and disease recurrence. Published gene sets with prognostic value in other studies were also tested. Results: Using supervised classification on the whole series, gene sets separating good and poor outcome could be found for all end points. However, when splitting tumors into training and validation groups, no robust classifiers could be found. Using Gene Set Enrichment analysis, several gene sets were found to be enriched in locoregional recurrences, although with high false-discovery rates. Previously published signatures for radiosensitivity, hypoxia, proliferation, 'wound,' stem cells, and chromosomal instability were not significantly correlated with outcome. However, a recently published signature for HNSCC defining a 'high-risk' group was shown to be predictive for locoregional control in our dataset. Conclusion: Gene sets can be found with predictive potential for locoregional control after combined radiation and chemotherapy in HNSCC. How treatment-specific these gene sets are needs further study

MBIs have aimed to facilitate physical and emotional adjustment to life with cancer through the cultivation and practice of mindfulness (ie, purposeful, nonjudgmental, moment-to-moment awareness. This descriptive review highlights three categories of outcomes that have been evaluated in MBI research with cancer patients – namely, symptom reduction, positive psychological growth, and biological outcomes. We also examine the clinical relevance of each targeted outcome, while describing recently published original studies to highlight novel applications of MBIs tailored to individuals with cancer. Accumulating evidence suggests that participation in a MBI contributes to reductions in psychological distress, sleep disturbance, and fatigue, and promotes personal growth in areas such as quality of life and spirituality. MBIs may also influence markers of immune function, hypothalamic–pituitary–adrenal axis regulation, and autonomic nervous system activity, though it remains unclear whether these biological changes translate to clinically important health benefits. We conclude by discussing methodological limitations of the extant literature, and implications of matching MBIs to the needs and preferences of cancer patients. Overall, the growing popularity of MBIs in cancer care must be balanced against scientific evidence for their impact on specific clinical outcomes. Keywords: mindfulness-based intervention

    ABSTRACT Objective: To investigate the neurodevelopmental outcome of childhood cancer survivors treated at the Eric Williams Medical Sciences Complex (EWMSC). Methods: Study participants were children treated at EWMSC from January 2003 to March 31, 2012 for various childhood cancers. All had completed treatment and were in remission. The McCarthy Scales of Children's Abilities (MSCA) was administered. The study was conducted from December 2011 to March 31, 2012. Results: Twenty-six children were evaluated, a response rate of 74%. There were 12 males and 14 females. Ages ranged from 3.25 to 9.00 years. Four (15.4%) children scored a general cognitive index (GCI) 132. The children's mean estimated mental age was found to be significantly lower than their mean actual age (p = 0.0086). Children treated for solid tumours had the least difference between their actual ages and estimated mental ages (p = 0.0301). The mean GCI for the genders was 97.4 for females and 81.0 for males; this difference was statistically significant (p = 0.0302). Age at diagnosis, type and length of treatment were not found to significantly affect development. Conclusion: The paediatric cancer survivors in this survey were found to have delays in their development. This group of children should have their development closely monitored. This would ensure that any delays in development can be discovered early and appropriate interventions instituted, so that childhood cancer survivors are adequately prepared for adult life beyond cancer.

  13. Outcomes of low-dose-rate brachytherapy for treatment of tongue cancer

    International Nuclear Information System (INIS)

    Between 1997 and 2006, 324 patients with T1-2 tongue cancer were treated with low-dose-rate brachytherapy at Tokyo Medical and Dental University Hospital. Their 5- and 10-year local control rates were 83% and 80%, respectively, and the occurrence rates of ≥ grade 3 mucositis and osteonecrosis were both 0.3%. During the study period, 9 other patients with tongue cancer underwent surgery and brachytherapy for positive surgical margins at our institution. Their 5- and 10-year local control rates were 76% and 64%. Moreover, 24 patients with tongue cancer received chemotherapy followed by brachytherapy, and their 5- and 10-year local control rates were both 100%. These outcomes are comparable to those of the patients who underwent low-dose-rate brachytherapy for T1-2 tongue cancer. In this study, 80% of patients treated by brachytherapy for T1-2 tongue cancer were cured with preserved function. However, for some patients with tumors unsuitable for treatment by brachytherapy alone, a combination of brachytherapy and surgery or chemotherapy may be a suitable treatment option. (author)

    OBJECT Surgical procedures and/or adjuvant therapies are effective modalities for the treatment of symptomatic spinal metastases. However, clinical results specific to the skin cancer spinal metastasis cohort are generally lacking. The purpose of this study was to systematically review the literature for treatments, clinical outcomes, and survival following the diagnosis of a skin cancer spinal metastasis and evaluate prognostic factors in the context of spinal skin cancer metastases stratified by tumor subtype. METHODS The authors performed a literature review using PubMed, Embase, CINAHL, and Web of Science to identify articles since 1950 that reported survival, clinical outcomes, and/or prognostic factors for the skin cancer patient population with spinal metastases. The methodological quality of reviews was assessed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) tool. RESULTS Sixty-five studies met the preset criteria and were included in the analysis. Of these studies, a total of 25, 40, 25, and 12 studies included patients who underwent some form of surgery, radiotherapy, chemotherapy, or observation alone, respectively. Sixty-three of the 65 included studies were retrospective in nature (Class of Evidence [CoE] IV), and the 2 prospective studies were CoE II. Based on the studies analyzed, the median overall survival for a patient with a spinal metastasis from a primary skin malignancy is 4.0 months; survival by tumor subtype is 12.5 months for patients with basal cell carcinoma (BCC), 4.0 months for those with melanoma, 4.0 months for those with squamous cell carcinoma, 3.0 months for those with pilomatrix carcinoma, and 1.5 months for those with Merkel cell carcinoma (p radiation) alone, or the combination of therapies was similar across interventions. Age, spinal region, and neurological status may be associated with poor survival following surgery. PMID:26544595

    Full Text Available The aim of this study was to evaluate the long term effects after discharge of a hospital-based geriatric liaison intervention to prevent postoperative delirium in frail elderly cancer patients treated with an elective surgical procedure for a solid tumour. In addition, the effect of a postoperative delirium on long term outcomes was examined.A three month follow-up was performed in participants of the Liaison Intervention in Frail Elderly study, a multicentre, prospective, randomized, controlled trial. Patients were randomized to standard treatment or a geriatric liaison intervention. The intervention consisted of a preoperative geriatric consultation, an individual treatment plan targeted at risk factors for delirium and daily visits by a geriatric nurse during the hospital stay. The long term outcomes included: mortality, rehospitalisation, Activities of Daily Living (ADL functioning, return to the independent pre-operative living situation, use of supportive care, cognitive functioning and health related quality of life.Data of 260 patients (intervention n = 127, Control n = 133 were analysed. There were no differences between the intervention group and usual-care group for any of the outcomes three months after discharge. The presence of postoperative delirium was associated with: an increased risk of decline in ADL functioning (OR: 2.65, 95% CI: 1.02-6.88, an increased use of supportive assistance (OR: 2.45, 95% CI: 1.02-5.87 and a decreased chance to return to the independent preoperative living situation (OR: 0.18, 95% CI: 0.07-0.49.A hospital-based geriatric liaison intervention for the prevention of postoperative delirium in frail elderly cancer patients undergoing elective surgery for a solid tumour did not improve outcomes 3 months after discharge from hospital. The negative effect of a postoperative delirium on late outcome was confirmed.Nederlands Trial Register, Trial ID NTR 823.

  17. Familial prostate cancer: outcome following radiation therapy with or without adjuvant androgen ablation

    International Nuclear Information System (INIS)

    Purpose: To compare the outcome of familial versus sporadic prostate carcinoma after definitive external radiation. Methods and Materials: Between 1987 and 1996, 1214 men with clinically localized prostate cancer (T1-T4, N0/NX, M0) received definitive radiation therapy in our department. By retrospective review of charts and questioning of patients, a record on the presence or absence of prostate cancer in a first degree relative was obtained in 1164 men. Univariate and multivariate analysis was performed on these cases with relapse or rising prostate-specific antigen (PSA), local recurrence, metastasis, and survival as endpoints. Results: Familiar prostate cancer was present in 148 of 1164 men (13%). Men with familial disease were slightly but significantly younger (mean 66 years) at diagnosis than those with sporadic disease (mean 68 years) (p = 0.02). Apart from this there were no significant differences between the two groups in T-stage, Gleason score, pretreatment PSA levels, DNA ploidy, or serum testosterone levels. There were no significant differences in treatment parameters including radiation dose and the use of adjuvant androgen ablation. With a median follow-up of 42 months, there was no difference in freedom from relapse or rising PSA at 6 years between those with a family history (54%) and those without a family history (58%) (p = 0.171). Likewise there was no difference between the two groups when local recurrence or metastasis was the endpoint. Multiple subgroup analyses (younger and older; T1/T2 and T3; low Gleason and high Gleason; no androgen ablation and androgen ablation; race) failed to reveal any differences in outcome in any category between familial and sporadic disease. Among patients with a rising post-treatment PSA profile, PSA doubling times were similar in those with sporadic and familial disease. Conclusions: This study provides no evidence for any substantial difference between familial and sporadic prostate cancer either in

  18. Correlation of microarray-based breast cancer molecular subtypes and clinical outcomes: implications for treatment optimization

    International Nuclear Information System (INIS)

    Optimizing treatment through microarray-based molecular subtyping is a promising method to address the problem of heterogeneity in breast cancer; however, current application is restricted to prediction of distant recurrence risk. This study investigated whether breast cancer molecular subtyping according to its global intrinsic biology could be used for treatment customization. Gene expression profiling was conducted on fresh frozen breast cancer tissue collected from 327 patients in conjunction with thoroughly documented clinical data. A method of molecular subtyping based on 783 probe-sets was established and validated. Statistical analysis was performed to correlate molecular subtypes with survival outcome and adjuvant chemotherapy regimens. Heterogeneity of molecular subtypes within groups sharing the same distant recurrence risk predicted by genes of the Oncotype and MammaPrint predictors was studied. We identified six molecular subtypes of breast cancer demonstrating distinctive molecular and clinical characteristics. These six subtypes showed similarities and significant differences from the Perou-Sørlie intrinsic types. Subtype I breast cancer was in concordance with chemosensitive basal-like intrinsic type. Adjuvant chemotherapy of lower intensity with CMF yielded survival outcome similar to those of CAF in this subtype. Subtype IV breast cancer was positive for ER with a full-range expression of HER2, responding poorly to CMF; however, this subtype showed excellent survival when treated with CAF. Reduced expression of a gene associated with methotrexate sensitivity in subtype IV was the likely reason for poor response to methotrexate. All subtype V breast cancer was positive for ER and had excellent long-term survival with hormonal therapy alone following surgery and/or radiation therapy. Adjuvant chemotherapy did not provide any survival benefit in early stages of subtype V patients. Subtype V was consistent with a unique subset of luminal A intrinsic

    Full Text Available Abstract Malnutrition is a significant factor in predicting cancer patients’ quality of life (QoL. We systematically reviewed the literature on the role of nutritional status in predicting QoL in cancer. We searched MEDLINE database using the terms “nutritional status” in combination with “quality of life” together with “cancer”. Human studies published in English, having nutritional status as one of the predictor variables, and QoL as one of the outcome measures were included. Of the 26 included studies, 6 investigated head and neck cancer, 8 gastrointestinal, 1 lung, 1 gynecologic and 10 heterogeneous cancers. 24 studies concluded that better nutritional status was associated with better QoL, 1 study showed that better nutritional status was associated with better QoL only in high-risk patients, while 1 study concluded that there was no association between nutritional status and QoL. Nutritional status is a strong predictor of QoL in cancer patients. We recommend that more providers implement the American Society of Parenteral and Enteral Nutrition (ASPEN guidelines for oncology patients, which includes nutritional screening, nutritional assessment and intervention as appropriate. Correcting malnutrition may improve QoL in cancer patients, an important outcome of interest to cancer patients, their caregivers, and families.

    Full Text Available Bridging the gap between animal or in vitro models and human disease is essential in medical research. Researchers often suggest that a biological mechanism is relevant to human cancer from the statistical association of a gene expression marker (a signature of this mechanism, that was discovered in an experimental system, with disease outcome in humans. We examined this argument for breast cancer. Surprisingly, we found that gene expression signatures-unrelated to cancer-of the effect of postprandial laughter, of mice social defeat and of skin fibroblast localization were all significantly associated with breast cancer outcome. We next compared 47 published breast cancer outcome signatures to signatures made of random genes. Twenty-eight of them (60% were not significantly better outcome predictors than random signatures of identical size and 11 (23% were worst predictors than the median random signature. More than 90% of random signatures >100 genes were significant outcome predictors. We next derived a metagene, called meta-PCNA, by selecting the 1% genes most positively correlated with proliferation marker PCNA in a compendium of normal tissues expression. Adjusting breast cancer expression data for meta-PCNA abrogated almost entirely the outcome association of published and random signatures. We also found that, in the absence of adjustment, the hazard ratio of outcome association of a signature strongly correlated with meta-PCNA (R(2 = 0.9. This relation also applied to single-gene expression markers. Moreover, >50% of the breast cancer transcriptome was correlated with meta-PCNA. A corollary was that purging cell cycle genes out of a signature failed to rule out the confounding effect of proliferation. Hence, it is questionable to suggest that a mechanism is relevant to human breast cancer from the finding that a gene expression marker for this mechanism predicts human breast cancer outcome, because most markers do.

    Studies suggest that patients with metastases limited in number and destination organ benefit from metastasis-directed therapy. Stereotactic body radiotherapy (SBRT) is commonly used for metastasis directed therapy in this group. However, the characterization of PET response following SBRT is unknown in this population. We analyzed our cohort of patients to describe the PET response following SBRT. Patients enrolled on a prospective dose escalation trial of SBRT to all known sites of metastatic disease were reviewed to select patients with pre- and post-therapy PET scans. Response to SBRT was characterized on PET imaging based on standard PET response criteria and compared to CT based RECIST criteria for each treated lesion. 31 patients had PET and CT data available before and after treatment for analysis in this study. In total, 58 lesions were treated (19 lung, 11 osseous, 11 nodal, 9 liver, 6 adrenal and 2 soft tissue metastases). Median follow-up was 14 months (range: 3–41). Median time to first post-therapy PET was 1.2 months (range; 0.5-4.1). On initial post-therapy PET evaluation, 96% (56/58) of treated metastases responded to therapy. 60% (35/58) had a complete response (CR) on PET and 36% (21/58) had a partial response (PR). Of 22 patients with stable disease (SD) on initial CT scan, 13 had CR on PET, 8 had PR, and one had SD. Of 21 metastases with PET PR, 38% became CR, 52% remained PR, and 10% had progressive disease on follow-up PET. 10/35 lesions (29%) with an initial PET CR progressed on follow-up PET scan with median time to progression of 4.11 months (range: 2.75-9.56). Higher radiation dose correlated with long-term PET response. PET response to SBRT enables characterization of metastatic response in tumors non-measurable by CT. Increasing radiation dose is associated with prolonged complete response on PET

  5. Locoregional treatment outcomes for inoperable anthracycline-resistant breast cancer

    International Nuclear Information System (INIS)

    Purpose: To assess the therapeutic outcomes and treatment-related morbidity of patients treated with radiation for inoperable breast cancer resistant to anthracycline-containing primary chemotherapy. Methods and Materials: We analyzed the medical records of breast cancer patients treated on five consecutive institutional trials who had been designated as having inoperable locoregional disease after completion of primary chemotherapy, without evidence of distant metastases at diagnosis. The cohort for this analysis was 38 (4.4%) of 867 patients enrolled in these trials. Kaplan-Meier statistics were used for survival analysis, and prognostic factors were compared using log-rank tests. The median follow-up of surviving patients was 6.1 years. Results: Thirty-two (84%) of the 38 patients were able to undergo mastectomy after radiotherapy. For the whole group, the overall survival rate at 5 years was 46%, with a distant disease-free survival rate of 32%. The 5-year survival rate for patients who were inoperable because of primary disease extent was 64% compared with 30% for those who were inoperable because of nodal disease extent (p = 0.0266). The 5-year rate of locoregional control was 73% for the surgically treated patients and 64% for the overall group. Of the 32 who underwent mastectomy, the 5-year rate of significant postoperative complications was 53%, with 4 (13%) requiring subsequent hospitalization and additional surgical revision. Preoperative radiation doses of ≥54 Gy were significantly associated with the development of complications requiring surgical treatment (70% vs. 9% for doses <54 Gy, p 0.0257). Conclusion: Despite the poorer prognosis of patients with inoperable disease after primary chemotherapy, almost one-half remained alive at 5 years and one-third were free of distant disease after multidisciplinary locoregional management. These patients have high rates of locoregional recurrence after preoperative radiotherapy and mastectomy, and the

    Positron emission tomography/computed tomography (PET/CT) is an important imaging tool for management of lung cancer and can be utilized in diagnosis, staging, restaging, treatment planning and evaluating treatment response. In the past decade PET/CT has proven to be beneficial for the prediction of prognosis and outcome. PET findings before and after treatment, the quantitative PET parameters such as standardized uptake value (SUV), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) as well as delayed PET/CT imaging can be used to determine patient prognosis and outcome. Other tracers such as hypoxia and proliferation marker tracers may be used for prognostication. The prognostic factors derived from PET/CT imaging help early development of risk-adapted treatment strategies, which provides cost-effective treatment and leads to improved patient management. Here, we discuss findings of studies related to application of PET/CT in lung cancer as well as some technical updates on quantitative PET/CT in lung cancer. PMID:26822467

    Background/Aims The efficacy and safety of endoscopic resection of colorectal cancer derived from sessile serrated adenomas or traditional serrated adenomas are still unknown. The aims of this study were to verify the characteristics and outcomes of endoscopically resected early colorectal cancers developed from serrated polyps. Methods Among patients who received endoscopic resection of early colorectal cancers from 2008 to 2011, cancers with documented pre-existing lesions were included. They were classified as adenoma, sessile serrated adenoma, or traditional serrated adenoma according to the baseline lesions. Clinical characteristics, pathologic diagnosis, and outcomes were reviewed. Results Overall, 208 colorectal cancers detected from 198 patients were included: 198 with adenoma, five with sessile serrated adenoma, and five with traditional serrated adenoma. The sessile serrated adenoma group had a higher prevalence of high-grade dysplasia (40.0% vs. 25.8%, Padenoma group. During follow-up, local recurrence did not occur after endoscopic resection of early colorectal cancers developed from serrated polyps. In contrast, two cases of metachronous recurrence were detected within a short follow-up period. Conclusions Cautious observation and early endoscopic resection are recommended when colorectal cancer from serrated polyp is suspected. Colorectal cancers from serrated polyp can be treated successfully with endoscopy. PMID:27433150

  10. P53 overexpression and outcome of radiation therapy in head and neck cancers

    International Nuclear Information System (INIS)

    Experimental studies have implicated the wild type p53 in cellular response to radiation. Whether altered p53 function can lead to changes in clinical radiocurability remains an area of ongoing study. This study was performed to investigate whether any correlation between change of p53 and outcome of curative radiation therapy in patients with head and neck cancers. Immunohistochemical analysis with a mouse monoclonal antibody (D0-7) specific for human p53 was used to detect to overexpression of protein in formalin fixed, paraffin-embedded tumor sample from 55 head and neck cancer patients treated with curative radiation therapy (median dose of 7020 cGy) from February 1988 to March 1996 at St. Mary's Hospital. Overexpression of p53 was correlated with locoregional control and survival using Kaplan-Meier method. A Cox regression multivariate analysis was performed that included all clinical variables and status of p53 expression. Thirty-seven (67.2%) patients showed overexpression of p53 by immunohistochemical staining in their tumor. One hundred percent of oral cavity, 76% of laryngeal, 66.7% of oropharyngeal, 66.7% of hypopharyngeal cancer showed p53 overexpression (p=0.05). The status of p53 had significant relationship with stage of disease (p=0.03) and history of smoking (p=0.001). The overexpression of p53 was not predictive of response rate to radiation therapy. The locoregional control was not significantly affected by p53 status. Overexpression of p53 didn't have any prognostic implication for disease free survival and overall survival. Primary site and stage of disease were significant prognostic factors for survival. The p53 overexpression as detected by immunohistochemical staining had significant correlation with stage, primary site of disease and smoking habit of patients. The p53 overexpression didn't have any predictive value for outcome of curative radiation therapy in a group of head and neck cancers

    Surgical resection remains the most important curative treatment modality for non-small cell lung cancer, but variations in short- and long-term surgical outcomes jeopardize the benefit of surgery for certain patients, operated on by certain types of surgeons, at certain types of institutions. We discuss current understanding of surgical quality measures, and their role in promoting understanding of the causes of outcome disparities after lung cancer surgery. We also discuss the use of minima...

    INTRODUCTION Patient-reported outcome (PRO) measures serve to capture vital patient information not otherwise obtained by primary study endpoints. This paper examines how PROs are utilized as endpoints in industry-sponsored metastatic breast cancer clinical trials. METHODS A search was conducted in the clinicaltrials.gov web site for trials involving common treatments for metastatic breast cancer. Thirty-eight clinical trials were identified which included a PRO endpoint in the study, and data were extracted and summarized. RESULTS Overall, 17 unique PRO questionnaires and 14 concepts of measurement were identified as secondary or exploratory endpoints. The Functional Assessment of Cancer Therapy—Breast was the most frequently utilized questionnaire, commonly implemented to assess quality of life. The EORTC QLQ-C30 was also frequently used to measure quality of life or pain. CONCLUSION This review shares insights into the role of PROs in trials for metastatic breast cancer from which treatment developers and other stakeholders can enhance successful implementation of the patient voice into future trials.

    Full Text Available orectal cancer obstructions are responsible for about 85% of colonic emergencies. The aim of this study was to investigate the results of urgent surgical intervention that applied in acute colonic obstructions related to cancer. Methods: In this study, 86 cases presenting with acute colonic obstruction who were operated with the diagnosis of colonic tumor between January 2010 and December 2010 were assessed retrospectively. Age, gender, symptoms on presentation, presence of concomitant disease, surgical methods applied, complication and mortality rates were recorded.Results: Fifty of the cases were male, 36 were female. The mean age was 63.6 years. Twenty cases had undergone emergency colonoscopic examination at diagnosis and an obstructive lesion had been observed. The surgical operations performed were right hemicolectomy in 18, sigmoid resection in 34, left hemicolectomy in 10, abdomino-perineal resection in 2, subtotal colectomy in 4, transverse colectomy in two. Primary anastomosis was performed in thirty-four cases. Mortality was observed in 12 cases. Conclusions: In selected cases of left colon cancers with obstruction, resection and primary anastomosis is generally possible. Those over 70, presence of co-morbidities, albumin level under 3 g/dl, ASA score 3 and higher, blood loss of more than 500 ml, and preoperative blood transfusion were related to the high postoperative morbidity.Key words: Colorectal cancer, obstruction, surgical treatment, outcome.

    The role of clusterin in tumor growth and progression remains unclear. Overexpression of cytoplasmic clusterin has been studied in aggressive colon tumors; however, no correlation between clusterin expression and survival in colorectal cancer has been identified to date. We assessed levels of clusterin expression in a group of stage II colorectal cancer patients to assess its utility as a prognostic marker. The study included 251 patients with stage II colorectal cancer. Tissue microarrays were constructed and immunohistochemistry done and correlated with clinical features and long term outcome. Dual immunofluorescence and confocal microscopy were used with terminal deoxynucleotidyl-transferase-mediated dUTP nick-end labeling probes and clusterin antibody to assess the degree of co localization. Percentage epithelial cytoplasmic staining was higher in tumor compared with nonadjacent normal mucosa (P < 0.001). Within the stromal compartment, percentage cytoplamic staining and intensity was lower in tumor tissue compared with normal nonadjacent mucosa (P < or = 0.001). Survival was significantly associated with percentage epithelial cytoplasmic staining (P < 0.001), epithelial cytoplasmic staining intensity (P < 0.001), percentage stromal cytoplasmic staining (P = 0.002), and stromal cytoplasmic staining intensity (P < 0.001). Clusterin levels are associated with poor survival in stage II colorectal cancer.

  15. Ezetimibe plus simvastatin cardiovascular outcomes study program.

    Padial, Luis Rodríguez

    2008-01-01

    Ezetimibe is a drug that impairs intestinal cholesterol absorption and decreases blood cholesterol levels. It has been shown that added to statins it can achieve a further reduction of low-density lipoprotein-cholesterol of 18-20%, overcoming the increase in absorption that follow the reduction in cholesterol synthesis by statins. Four major outcome trials are underway to study the effect of ezetimibe plus simvastatin in different subsets of high-risk patients: familiar hypercholesterolemia, degenerative aortic stenosis, chronic kidney disease and acute coronary syndrome. Hopefully, in the next few years the information provided by these trials will allow us to further reduce the increasing burden of cardiovascular disease. PMID:18095904

    Few studies have reported prospective data on psychosocial outcomes after genetic counselling in families with suspected hereditary non-polyposis colorectal cancer (HNPCC). This prospective study examines the impact of multidisciplinary risk counselling on the psychosocial outcome of 139 affected cancer patients and 233 family members without cancer at risk for HNPCC. Participants completed questionnaires specific to HNPCC before and 8 weeks after attending the familial cancer clinic. Affected patients' levels of distress were closely related to their health status and exceeded that of unaffected individuals, as did worry regarding their relatives' risk. A significant reduction in general anxiety (Hospital Anxiety and Depression Scale), distress specific to familial CRC (Impact of Events Scale) and general cancer worry (Distress Hereditary Disorder) was demonstrated after counselling in both affected patients and unaffected individuals. Reduction in distress was more pronounced in affected patients given a high risk of HNPCC compared with those at intermediate risk. Among unaffected individuals, distress declined regardless of what clinical risk they were assigned. Their perceptions of risk and cancer-related threat declined, while confidence in effective surveillance increased. These results suggest the beneficial effects of multidisciplinary counselling even when high-risk information is conveyed. A patient's previous cancer experience is likely to contribute to clinically relevant distress (15% of those patients), indicating the need for appropriate counselling. PMID:18954412

  20. Outcomes After Intensity-Modulated Versus Conformal Radiotherapy in Older Men With Nonmetastatic Prostate Cancer

    International Nuclear Information System (INIS)

    Purpose: There is little evidence comparing complications after intensity-modulated (IMRT) vs. three-dimensional conformal radiotherapy (CRT) for prostate cancer. The study objective was to test the hypothesis that IMRT, compared with CRT, is associated with a reduction in bowel, urinary, and erectile complications in elderly men with nonmetastatic prostate cancer. Methods and Materials: We undertook an observational cohort study using registry and administrative claims data from the SEER-Medicare database. We identified men aged 65 years or older diagnosed with nonmetastatic prostate cancer in the United States between 2002 and 2004 who received IMRT (n = 5,845) or CRT (n = 6,753). The primary outcome was a composite measure of bowel complications. Secondary outcomes were composite measures of urinary and erectile complications. We also examined specific subsets of bowel (proctitis/hemorrhage) and urinary (cystitis/hematuria) events within the composite complication measures. Results: IMRT was associated with reductions in composite bowel complications (24-month cumulative incidence 18.8% vs. 22.5%; hazard ratio [HR] 0.86; 95% confidence interval [CI], 0.79–0.93) and proctitis/hemorrhage (HR 0.78; 95% CI, 0.64–0.95). IMRT was not associated with rates of composite urinary complications (HR 0.93; 95% CI, 0.83–1.04) or cystitis/hematuria (HR 0.94; 95% CI, 0.83–1.07). The incidence of erectile complications involving invasive procedures was low and did not differ significantly between groups, although IMRT was associated with an increase in new diagnoses of impotence (HR 1.27, 95% CI, 1.14–1.42). Conclusion: IMRT is associated with a small reduction in composite bowel complications and proctitis/hemorrhage compared with CRT in elderly men with nonmetastatic prostate cancer.

    Full Text Available Abstract Background A previous study evaluated the intra-tumoral heterogeneity observed in the uptake of F-18 fluorodeoxyglucose (FDG in pre-treatment positron emission tomography (PET scans of cancers of the uterine cervix as an indicator of disease outcome. This was done via a novel statistic which ostensibly measured the spatial variations in intra-tumoral metabolic activity. In this work, we argue that statistic is intrinsically non-spatial, and that the apparent delineation between unsuccessfully- and successfully-treated patient groups via that statistic is spurious. Methods We first offer a straightforward mathematical demonstration of our argument. Next, we recapitulate an assiduous re-analysis of the originally published data which was derived from FDG-PET imagery. Finally, we present the results of a principal component analysis of FDG-PET images similar to those previously analyzed. Results We find that the previously published measure of intra-tumoral heterogeneity is intrinsically non-spatial, and actually is only a surrogate for tumor volume. We also find that an optimized linear combination of more canonical heterogeneity quantifiers does not predict disease outcome. Conclusions Current measures of intra-tumoral metabolic activity are not predictive of disease outcome as has been claimed previously. The implications of this finding are: clinical categorization of patients based upon these statistics is invalid; more sophisticated, and perhaps innately-geometric, quantifications of metabolic activity are required for predicting disease outcome.

    Full Text Available Abstract Background Management of pain related to advanced or metastatic cancer, although the availability of several pharmacological and non-pharmacological interventions and the existence of well-known guidelines and protocols, is often difficult and inadequate. Evidence of the relative effectiveness of current options for treating cancer pain from comparative randomized studies is scanty. Methods In the context of a wider project, a multicenter, open label, prospective Outcome Research study will be launched in Italy in 2006 to investigate the epidemiology of cancer pain and of its treatments, the quality of analgesic-drug therapy and the effectiveness of alternative analgesic strategies in a large, prospective, unselected cohort of cancer patients using the state-of-the art of patient-reported-outcomes. About 100 Italian centers will recruit 2500 patients with advanced/progressive/metastatic cancer with pain (related to the cancer disease requiring analgesic treatments. Each center is expected to recruit 25 consecutive and eligible patients during the study inception period. Approximately two months will be allowed for subject recruitment and enrollment. Subject evaluation and follow-up will be for 3 months. The effect on outcomes of various therapeutic analgesic options administered by physicians, given the observational approach where patients are not assigned at random to different treatments, will be compared using the propensity score approach, allowing the adjustment for treatment selection bias. Later, after the launch of the observational study and on the basis of results, in specific subsamples of patients and in select centers of the network, a Randomized Controlled Trial will be carried out to formally compare the efficacy of alternative analgesic strategies, with particular emphasis on oral morphine (as comparator and buprenorphine patch (as experimental arm.

    The aim of this study was to quantify the impact of initial tumor volume (TV) on radiotherapy (RT) outcome in patients with T2 glottic cancer. Initial TV was calculated for 115 consecutive patients with T2 glottic cancer who had been treated with definitive RT alone at a single institution. The results showed strong correlations of TV with 3-year local tumor control (LTC) and disease-free survival (DFS). For TV ≤ 0.7 cm{sup 3}, 3-year LTC was 83 %; for TV 0.7-3.6 cm{sup 3} this was 70 % and for TV 3.6-17 cm{sup 3} 44 %. Analysis of total dose vs. initial TV showed that larger T2 glottic tumors with a TV of around 5 cm{sup 3} (2-2.5 cm in diameter with 10{sup 10} cancer cells) need an extra 6.5 Gy to achieve similar 3-year LTC rates as for small tumors with a TV of 0.5 cm{sup 3} (∝1 cm in diameter with 10{sup 9} cancer cells). Although classification of tumors according to TV cannot replace TNM staging in daily practice, it could represent a valuable numerical supplement for planning the optimal dose fractionation scheme for individual patients.

    Total elbow arthroplasty (TEA) is becoming a popular alternative to arthrodesis for patients with end-stage elbow arthrosis and comminuted distal humeral fractures. Prior outcome studies have primarily focused on surgical findings. Our purpose is to determine the radiographic outcome of TEA and to correlate with clinical symptoms such as pain. This is an IRB-approved retrospective review from 2005 to 2015 of all patients with semiconstrained TEA. All available elbow radiographs and clinical data were reviewed. Data analysis included descriptive statistics and Kaplan-Meier survival curves for radiographic and clinical survival. A total of 104 total elbow arthroplasties in 102 patients were reviewed; 75 % were in women and the mean patient age was 63.1 years. Mean radiographic follow-up was 826 days with average of four radiographs per patient. Seventy TEAs (67 %) developed radiographic complications, including heterotopic ossification (48 %), perihardware lucency (27 %), periprosthetic fracture (23 %), hardware subluxation/dislocation (7 %), polyethylene wear (3 %), and hardware fracture/dislodgement (3 %); 56 patients (55 %) developed symptoms of elbow pain or instability and 30 patients (30 %) underwent at least one reoperation. In patients with radiographic complications, 66 % developed elbow pain, compared to 19 % of patients with no radiologic complications (p = 0.001). Of the patients with radiographic complications, 39 % had at least one additional surgery compared to 0 % of patients without radiographic complications (p = 0.056). Radiographic complications are common in patients after total elbow arthroplasty. There is a strong positive association between post-operative radiographic findings and clinical outcome. Knowledge of common postoperative radiographic findings is important for the practicing radiologist. (orig.)

  6. Low expression of TFPI-2 associated with poor survival outcome in patients with breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study is to evaluate the prognostic value of TFPI-2 expression in breast cancer patients through examining the correlation between TFPI-2 expression and breast cancer clinicopathologic features. Immunohistochemical staining combined with digital image analysis was used to quantify the expression of TFPI-2 protein in breast tumor tissues. For evaluation of the prognostic value of TFPI-2 expression to each clinicopathologic factor, Kaplan-Meier method and COX’s Proportional Hazard Model were employed. TFPI-2 expression was significantly correlated with tumor size, lymph node metastasis, histologic grade, clinical stage, and vessel invasion. More importantly, TFPI-2 expression was also associated with disease-free survival (DFS) of breast cancer patients. We found that patients with high TFPI-2 expression had longer DFS compared with those with low or negative expression of TFPI-2 (P <0.05, log-rank test). Cox’s regression analysis indicated that TFPI-2 expression, histologic grade, and vessel invasion might be significant prognostic factors for DFS, while TFPI-2 expression and histologic grade were the most significant independent predictors for tumor recurrence. Compared with the group with low/high TFPI-2 expression, the TFPI-2 negative group was more likely to have tumor relapse. The hazard ratio of DFS is 0.316 (P <0.01). Low or negative expression of TFPI-2 is associated with breast cancer progression, recurrence and poor survival outcome after breast cancer surgery. TFPI-2 expression in breast tumors is a potential prognostic tool for breast cancer patients

  7. Issues for researchers to consider when using health-related quality of life outcomes in cancer research.

    2011-09-01

    Maintaining quality of life for patients with cancer is a key factor when developing services related to diagnosis, treatment, recovery and/or terminal care. This paper questions whether health-related quality of life (HRQoL) is an appropriate measure of quality of life given that it does not assess factors reported by patients as being most influential, e.g. contact with family and social/cultural interaction. Ambiguity related to the definition and understanding of anxiety, depression and distress as outcomes commonly used by clinicians and researchers when measuring HRQoL in cancer research is also addressed by this paper. The findings of many cancer studies are interpreted and presented on very broad and poorly defined concepts thus preventing the development of a coherent and true understanding of how these outcomes influence quality of life for cancer patients. The authors of this paper conclude that the documentation and clear explanation of the concepts underpinning the choice of instrument and study design is essential but also the inclusion of outcomes related to social support and interaction would provide a more accurate account of quality of life issues in cancer research.

    Background: Cancer patients commonly suffer from weight loss since rapid tumor growth can cause catabolic metabolism and depletion of energy stores such as abdominal fat. In locally advanced pancreatic cancer this is even more pronounced due to abdominal pain, fatigue, nausea or malnutrition. In the present article, we quantify this frequently observed weight loss and assess its impact on outcome and survival. Methods: Data on demographics, biometrics, toxicity and survival were collected for the last 100 patients treated with neoadjuvant chemoradiation for locally advanced pancreatic cancer at our department (45.0 Gy and boost up to 54.0 Gy plus concurrent and subsequent gemcitabine), and the subcutaneous fat area at the umbilicus level was measured by computer tomography before and after chemoradiation. Results: After chemoradiation, patients showed a highly statistically significant weight loss and reduction of the subcutaneous fat area. We could determine a very strong correlation of subcutaneous fat area to patient BMI. By categorizing patients according to their BMI based on the WHO classification as slender, normal, overweight and obese, we found improved but not statistically significant survival among obese patients. Accordingly, patients who showed less weight loss tended to survive longer. Conclusions: In this study, patients with pancreatic cancer lost weight during chemoradiation and their subcutaneous fat diminished. Changes in subcutaneous fat area were highly correlated with patients' BMI. Moreover, obese patients and patients who lost less weight had an improved outcome after treatment. Although the extent of weight loss was not significantly correlated with survival, the observed trend warrants greater attention to nutritional status in the future. (orig.)

    The immune system constitutes one of the host factors modifying outcomes in ovarian cancer. Regulatory T cells (Tregs) are believed to be a major factor in preventing the immune response from destroying ovarian cancers. Understanding mechanisms that regulate Tregs in the tumor microenvironment could lead to the identification of novel targets aimed at reducing their influence. In this study, we used immunofluorescence-based microscopy to enumerate Tregs, total CD4 T cells, and CD8(+) cytotoxic T cells in fresh frozen tumors from over 400 patients with ovarian cancer (>80 % high-grade serous). We sought to determine whether Tregs were associated with survival and genetic variation in 79 genes known to influence Treg induction, trafficking, or function. We used Cox regression, accounting for known prognostic factors, to estimate hazard ratios (HRs) associated with T cell counts and ratios. We found that the ratios of CD8 T cells and total CD4 T cells to Tregs were associated with improved overall survival (CD8/Treg HR 0.84, p = 0.0089; CD4/Treg HR 0.88, p = 0.046) and with genetic variation in IL-10 (p = 0.0073 and 0.01, respectively). In multivariate analyses, the associations between the ratios and overall survival remained similar (IL-10 and clinical covariate-adjusted CD8/Treg HR 0.85, p = 0.031; CD4/Treg HR 0.87, p = 0.093), suggesting that this association was not driven by variation in IL-10. Thus, integration of novel tumor phenotyping measures with extensive clinical and genetic information suggests that the ratio of T cells to Tregs may be prognostic of outcome in ovarian cancer, regardless of inherited genotype in genes related to Tregs.

    Full Text Available Abstract Background In India, 72% of the population resides in rural areas and 30-40% of cancers are found in the oral cavity. The majority of Haryana residents live in villages where inadequate medical facilities, no proper primary care infrastructure or cancer screening tools and high levels of illiteracy all contribute to poor oral cancer (OC outcomes. In this challenging environment, the objective of this study was to assess the association between various risk factors for OC among referrals for suscipious lesions and to design and pilot test a collaborative community-based effort to identify suspicious lesions for OC. Methods Setting: Community-based cross sectional OC screening. Participants: With help from the Department of Health (DOH, Haryana and the local communities, we visited three villages and recruited 761 participants of ages 45-95 years. Participants received a visual oral cancer examination and were interviewed about their dental/medical history and personal habits. Pregnant women, children and males/females below 45 years old with history of OC were excluded. Main outcome: Presence of a suspicious oral lesion. Results Out of 761 participants, 42 (5.5% were referred to a local dentist for follow-up of suspicious lesions. Males were referred more than females. The referral group had more bidi and hookah smokers than non smokers as compared to non referral group. The logistic regression analysis revealed that smoking bidi and hookah (OR = 3.06 and 4.42 were statistically significant predictors for suspicious lesions. Conclusions Tobacco use of various forms in rural, northern India was found to be quite high and a main risk factor for suspicious lesions. The influence of both the DOH and community participation was crucial in motivating people to seek care for OC.

    Patients with pancreatic cancer have a high frequency of concurrent diabetes. This study is aimed to demonstrate the impact of diabetes on clinical outcome of pancreatic cancer. Clinical and epidemiological information was collected from medical records or by personal interview in 1328 patients with pancreatic ductal adenocarcinoma. Diabetes was defined by a known medical history, or abnormal fasting blood glucose (FBG) and HbA1c levels within three months of the cancer diagnosis. Duration of ≤3 years was used as the cutoff to arbitrarily define the new-onset and long-term diabetes. Logistic regression, Kaplan-Meier plot, log-rank test and Cox regression models were employed in the data analysis. Elevated level of FBG or HbA1c was observed in 24.7% and 11.5% of the patients without a known diabetes history, respectively. The prevalence of DM was 44.4% and was comparable by strata of tumor stage. New-onset diabetes was a significant independent predictor for risk of death in metastatic patients (HR=1.35, 95% CI=1.11-1.63, P=0.002) and in all patients (HR=1.23, 95% CI=1.09-1.40, P=0.001). Both new-onset and long term diabetes were significantly associated with older age, obesity, hypertension and coronary artery disease as well as weight loss. New-onset diabetes was also significantly related to larger tumors and elevated level of CA19-9 but not to tumor site and presence of biliary obstruction. Diabetes in general and new-onset diabetes in particular, is associated with poor outcome of pancreatic cancer. New-onset and long-term diabetes share common risk factors for type 2 diabetes.

  16. Outcome after neoadjuvant chemoradiation and correlation with nutritional status in patients with locally advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Background: Cancer patients commonly suffer from weight loss since rapid tumor growth can cause catabolic metabolism and depletion of energy stores such as abdominal fat. In locally advanced pancreatic cancer this is even more pronounced due to abdominal pain, fatigue, nausea or malnutrition. In the present article, we quantify this frequently observed weight loss and assess its impact on outcome and survival. Methods: Data on demographics, biometrics, toxicity and survival were collected for the last 100 patients treated with neoadjuvant chemoradiation for locally advanced pancreatic cancer at our department (45.0 Gy and boost up to 54.0 Gy plus concurrent and subsequent gemcitabine), and the subcutaneous fat area at the umbilicus level was measured by computer tomography before and after chemoradiation. Results: After chemoradiation, patients showed a highly statistically significant weight loss and reduction of the subcutaneous fat area. We could determine a very strong correlation of subcutaneous fat area to patient BMI. By categorizing patients according to their BMI based on the WHO classification as slender, normal, overweight and obese, we found improved but not statistically significant survival among obese patients. Accordingly, patients who showed less weight loss tended to survive longer. Conclusions: In this study, patients with pancreatic cancer lost weight during chemoradiation and their subcutaneous fat diminished. Changes in subcutaneous fat area were highly correlated with patients' BMI. Moreover, obese patients and patients who lost less weight had an improved outcome after treatment. Although the extent of weight loss was not significantly correlated with survival, the observed trend warrants greater attention to nutritional status in the future. (orig.)

    In limited-resource countries, cancer kills more people annually than AIDS, tuberculosis and malaria combined. Programs targeting early detection and treatment of cancer are virtually non-existent due to insufficient funding and attention given to this emerging health challenge. Breast cancer is the most common cancer in women worldwide and is also the leading cause of cancer-related death in females. In developing countries such as Uganda, breast cancer incidence is increasing and typically presents at an advanced stage of disease, for which treatment options are limited. Inadequate knowledge and understanding of the disease, social stigma, and barriers to care all contribute to a poorer prognosis. There are many challenges to reducing breast cancer incidence and mortality globally; however, there is evidence to suggest that advocacy and education, in particular through the efforts of breast cancer survivors and their partners, can play a critical role in improving overall outcomes in limited-resource countries.

    Full Text Available TERT is of great importance in cancer initiation and progression. Many studies have demonstrated the TERT polymorphisms as risk factors for many cancer types, including lung cancer. However, the impacts of TERT variants on cancer progression and treatment efficacy have remained controversial. This study aimed to investigate the association of TERT polymorphisms with clinical outcome of advanced non-small cell lung cancer (NSCLC patients receiving first-line platinum-based chemotherapy, including response rate, clinical benefit, progression-free survival (PFS, overall survival (OS, and grade 3 or 4 toxicity. Seven polymorphisms of TERT were assessed, and a total of 1004 inoperable advanced NSCLC patients treated with platinum-based chemotherapy were enrolled. It is exhibited that the variant heterozygote of rs4975605 showed significant association with a low rate of clinical benefit, and displayed a much stronger effect in never-smoking female subset, leading to the clinical benefit rate decreased from 82.9% (C/C genotype to 56.4% (C/A genotype; adjusted OR, 3.58; P=1.40×10(-4. It is also observed that the polymorphism rs2736109 showed significant correlation with PFS (log-rank P=0.023. In age > 58 subgroup, patients carrying the heterozygous genotype had a longer median PFS than those carrying the wild-type genotypes (P=0.002. The results from the current study, for the first time to our knowledge, provide suggestive evidence of an effect of TERT polymorphisms on disease progression variability among Chinese patients with platinum-treated advanced NSCLC.

  19. Validation that Metabolic Tumor Volume Predicts Outcome in Head-and-Neck Cancer

    International Nuclear Information System (INIS)

    Purpose: We have previously reported that metabolic tumor volume (MTV) obtained from pretreatment 18F-fluorodeoxydeglucose positron emission tomography (FDG PET)/ computed tomography (CT) predicted outcome in patients with head-and-neck cancer (HNC). The purpose of this study was to validate these results on an independent dataset, determine whether the primary tumor or nodal MTV drives this correlation, and explore the interaction with p16INK4a status as a surrogate marker for human papillomavirus (HPV). Methods and Materials: The validation dataset in this study included 83 patients with squamous cell HNC who had a FDG PET/CT scan before receiving definitive radiotherapy. MTV and maximum standardized uptake value (SUVmax) were calculated for the primary tumor, the involved nodes, and the combination of both. The primary endpoint was to validate that MTV predicted progression-free survival and overall survival. Secondary analyses included determining the prognostic utility of primary tumor vs. nodal MTV. Results: Similarly to our prior findings, an increase in total MTV of 17 cm3 (difference between the 75th and 25th percentiles) was associated with a 2.1-fold increase in the risk of disease progression (p = 0.0002) and a 2.0-fold increase in the risk of death (p = 0.0048). SUVmax was not associated with either outcome. Primary tumor MTV predicted progression-free (hazard ratio [HR] = 1.94; p INK4a-positive oropharyngeal cancer. Conclusions: This study validates our previous findings that MTV independently predicts outcomes in HNC. MTV should be considered as a potential risk-stratifying biomarker in future studies of HNC.

    Full Text Available Abstract Background To determine the relationships of potential occupational exposure to antineoplastic drugs with cancer incidence and adverse pregnancy outcomes in a historical prospective cohort study of female registered nurses (RNs from British Columbia, Canada (BC. Methods Female RNs registered with a professional regulatory body for at least one year between 1974 and 2000 formed the cohort (n = 56,213. The identifier file was linked to Canadian cancer registries. An RN offspring cohort from 1986 was created by linkages with the BC Birth and Health Status Registries. Exposure was assessed by work history in oncology or cancer agencies (method 1 and by estimating weighted duration of exposure developed from a survey of pharmacists and nursing unit administrators of all provincial hospitals and treatment centers and the work history of the nurses (method 2. Relative risks (RR were calculated using Poisson regression for cancer incidence and odds ratios (OR were calculated for congenital anomaly, stillbirth, low birth weight, and prematurity incidence, with 95% confidence intervals. Results In comparison with other female RNs, method 1 revealed that RNs who ever worked in a cancer center or in an oncology nursing unit had an increased risk of breast cancer (RR = 1.83; 95% CI = 1.03 - 3.23, 12 cases and their offspring were at risk for congenital anomalies of the eye (OR = 3.46, 95% CI = 1.08 - 11.14, 3 cases. Method 2 revealed that RNs classified as having the highest weighted durations of exposure to antineoplastic drugs had an excess risk of cancer of the rectum (RR = 1.87, 95% CI = 1.07 - 3.29, 14 cases. No statistically significant increased risks of leukemia, other cancers, stillbirth, low birth weight, prematurity, or other congenital anomalies in the RNs' offspring were noted. Conclusions Female RNs having had potential exposure to antineoplastic drugs were not found to have an excess risk of leukemia, stillbirth, or congenital

  1. Outcome analysis of 300 prostate cancer patients treated with neoadjuvant androgen deprivation and hypofractionated radiotherapy

    International Nuclear Information System (INIS)

    Purpose: Neoadjuvant androgen deprivation and radical radiotherapy is an established treatment for localized prostate carcinoma. This study sought to analyze the outcomes of patients treated with relatively low-dose hypofractionated radiotherapy. Methods and Materials: Three hundred patients with T1-T3 prostate cancer were treated between 1996 and 2001. Patients were prescribed 3 months of neoadjuvant androgen deprivation before receiving 5250 cGy in 20 fractions. Patients' case notes and the oncology database were used to retrospectively assess outcomes. Median follow-up was 58 months. Results: Patients presented with prostate cancer with poorer prognostic indicators than that reported in other series. At 5 years, the actuarial cause-specific survival rate was 83.2% and the prostate-specific antigen (PSA) relapse rate was 57.3%. Metastatic disease had developed in 23.4% of patients. PSA relapse continued to occur 5 years from treatment in all prognostic groups. Independent prognostic factors for relapse included treatment near the start of the study period, neoadjuvant oral anti-androgen monotherapy rather than neoadjuvant luteinizing hormone releasing hormone therapy, and diagnosis through transurethral resection of the prostate rather than transrectal ultrasound. Conclusion: This is the largest reported series of patients treated with neoadjuvant androgen deprivation and hypofractionated radiotherapy in the United Kingdom. Neoadjuvant hormonal therapy did not appear to adequately compensate for the relatively low effective radiation dose used

    To conduct a systematic review of the risks of short-term outcomes after major treatments for clinically localised prostate cancer. MEDLINE, EMBASE and the Cochrane Library were searched from 2004 to January 2013. Study arms that included ≥100 men with localised prostate cancer in receipt of surgery, radiotherapy or active surveillance and reported symptomatic and quality-of-life (QoL) data from 6 to 60 months after treatment were eligible. Data were extracted by one reviewer and checked by another. In all, 64 studies (80 treatment cohorts) were included. Most were single treatment cohorts from the USA or Europe. Radiotherapy was the most common treatment (40 cohorts, including 31 brachytherapy cohorts) followed by prostatectomy (39 cohorts), with only one active surveillance cohort. Most frequently measured symptoms were urinary, followed by sexual, and bowel; QoL was assessed in only 17 cohorts. Most studies used validated measures, although poor data reporting and differences between studies meant that it was not possible to pool data. Data on the precise impact of short-term symptomatic and QoL outcomes after treatment for localised prostate cancer are of insufficient quality for clear guidance to men about the risks to these aspects of their lives. It is important that future studies focus on collecting core outcomes through validated measures and comply with reporting guidelines, so that clear and accurate information can be derived for men considering screening or treatment for prostate cancer.

  3. Economic and quality-of-life outcomes in head and neck cancer

    International Nuclear Information System (INIS)

    Head and neck cancer offers a special and unique challenge to physicians and patients. Treatment of cancers in this part of the body, especially surgical resection, can cause profound changes in quality-of-life. The patient's ability to work, earn a living, articulate speech, communicate, have social interaction, and live a normal life, can be affected in a major way. Therefore, physicians and patients must look beyond the obvious oncologic outcomes of locoregional control, distant metastasis free survival, and overall survival. These outcomes must be assessed along with detailed, quality-of-life and economic outcomes, in order to properly manage patients. It is also mandatory that patients have a clear understanding of all their treatment options, and the implications of these options on cancer control and quality-of-life. This panel will focus on the available methods to assess quality-of-life and economic outcomes in head and neck cancer management. It will also highlight areas where new oncologic strategies are utilized which emphasize organ and function preservation. This latter area is an important aspect of modern clinical research and practice. In particular, management of cancers of the tongue, larynx, and hypopharynx offer special opportunities. Resection of these organs can produce debilitating functional outcomes. New multidisciplinary approaches to treat patients while avoiding primary resection have been developed. The oncologic and quality-of-life/economic outcomes will be assessed for these organ preserving strategies

    AIM: To compare outcomes for patients presenting withstage IV colorectal cancer and an asymptomatic primary tumour, undergoing primary tumour resection(PTR) plus palliative chemotherapy vs primary chemotherapy up-front.METHODS: A literature search was conducted using MEDLINE and EMBASE. The primary outcome was overall survival. Secondary outcomes included perioperative mortality, morbidity and delayed surgical intervention rates in patients undergoing PTR and subsequent complication rates in patients with an un-resected primary tumour. Tertiary outcomes included impact on systemic treatment and identification of prognostic factors relevant for survival in this cohort. RESULTS: Twenty non-randomised studies met the inclusion criteria. Eleven studies included comparative overall survival data. Three studies showed an overall survival advantage for PTR, 7 studies showed no statistically significant advantage, and 1 study showed a significant worsening in survival in the surgical group. The perioperative mortality rate ranged from 0% to 8.5%, and post-operative morbidity rate from 10% to 35%, mainly minor complications that did not preclude subsequent chemotherapy. The rate of delayed primarytumour related symptoms, most commonly obstruction, in patients with an un-resected primary tumour ranged from 3% to 46%. The strongest independent poor prognostic factor was extensive hepatic metastases, in addition to poor performance status, M1 b stage and non-use of modern chemotherapy agents.CONCLUSION: Based on the current literature, both PTR and up front chemotherapy appear appropriate initial management strategies, with a trend towards an overall survival advantage with PTR. The procedure has a low post-operative mortality, and most complications are transient and minor. The results of recruiting randomised trials are eagerly anticipated.

  8. Maximizing outcomes in genitourinary cancers across the treatment continuum.

    Fitzpatrick, John M

    2011-04-01

    Key controversies concerning the management of genitourinary cancers across the treatment continua were discussed at the second annual Interactive Genitourinary Cancer Conference (IGUCC) held in February 2010 in Athens, Greece. Prostate cancer is the most common form of cancer among western men and prevention strategies are needed. Trials evaluating 5α-reductase inhibitors have reported beneficial and clinically meaningful results, but uptake remains low for primary prostate cancer prevention. Prostate cancer detection programmes are also important as curative treatments for advanced disease are unavailable. Two large landmark randomized controlled trials reported conflicting results concerning screening efficacy and uncovered high levels of over-diagnosis and potential over-treatment. Tailored management strategies after diagnosis are important and predictive markers that distinguish between aggressive and indolent tumours are needed. The majority of newly diagnosed cases of prostate cancer are clinically localized. Active surveillance of favourable risk patients may be beneficial in the intermediate term, while an integrated approach of multi-modality therapy in patients with adverse features is recommended. The benefits of new technologies such as high-intensity focused ultrasound (HIFU) and robotic prostatectomy have not been established in prospective randomized trials vs current standards of care. A multidisciplinary approach is essential to evolving the management of advanced prostate cancer into a chronic disease paradigm. Docetaxel plus prednisone is the standard first-line chemotherapy for patients with metastatic castration-resistant prostate cancer (mCRPC), but the optimal timing of chemotherapy initiation has not been addressed in randomized clinical trials. Retrospective analyses suggest that asymptomatic patients with adverse prognostic factors for survival may also benefit from receiving chemotherapy. Bladder cancer is a common malignancy and the

  9. Impact of Radiotherapy on Fertility, Pregnancy, and Neonatal Outcomes in Female Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: Radiation has many potential long-term effects on cancer survivors. Female cancer patients may experience decreased fertility depending on the site irradiated. Oncologists should be aware of these consequences and discuss options for fertility preservation before initiating therapy. Methods and Materials: A comprehensive review of the existing literature was conducted. Studies reporting the outcomes for female patients treated with cranio-spinal, abdominal, or pelvic radiation reporting fertility, pregnancy, or neonatal-related outcomes were reviewed. Results: Cranio-spinal irradiation elicited significant hormonal changes in women that affected their ability to become pregnant later in life. Women treated with abdomino-pelvic radiation have an increased rate of uterine dysfunction leading to miscarriage, preterm labor, low birth weight, and placental abnormalities. Early menopause results from low-dose ovarian radiation. Ovarian transposition may decrease the rates of ovarian dysfunction. Conclusions: There is a dose-dependent relationship between ovarian radiation therapy (RT) and premature menopause. Patients treated with RT must be aware of the impact of treatment on fertility and explore appropriate options.

  10. Boron neutron capture therapy outcomes for advanced or recurrent head and neck cancer

    International Nuclear Information System (INIS)

    We retrospectively review outcomes of applying boron neutron capture therapy (BNCT) to unresectable advanced or recurrent head and neck cancers. Patients who were treated with BNCT for either local recurrent or newly diagnosed unresectable head or neck cancers between December 2001 and September 2007 were included. Clinicopathological characteristics and clinical outcomes were retrieved from hospital records. Either a combination of borocaptate sodium and boronophenylalanine (BPA) or BPA alone were used as boron compounds. In all the treatment cases, the dose constraint was set to deliver a dose <10–12 Gy-eq to the skin or oral mucosa. There was a patient cohort of 62, with a median follow-up of 18.7 months (range, 0.7–40.8). A total of 87 BNCT procedures were performed. The overall response rate was 58% within 6 months after BNCT. The median survival time was 10.1 months from the time of BNCT. The 1- and 2-year overall survival (OS) rates were 43.1% and 24.2%, respectively. The major acute Grade 3 or 4 toxicities were hyperamylasemia (38.6%), fatigue (6.5%), mucositis/stomatitis (9.7%) and pain (9.7%), all of which were manageable. Three patients died of treatment-related toxicity. Three patients experienced carotid artery hemorrhage, two of whom had coexistent infection of the carotid artery. This study confirmed the feasibility of our dose-estimation method and that controlled trials are warranted. (author)

    Several single-nucleotide polymorphisms (SNPs) associated with breast cancer risk have been identified through genome-wide association studies. This study investigated the association of eight risk SNPs with breast cancer disease-free survival and overall survival rates. Results suggest that two previously identified breast cancer risk susceptibility loci may influence breast cancer prognosis or comorbid conditions associated with overall survival.

    Reliable biomarkers predicting resistance or sensitivity to anti-cancer therapy are critical for oncologists to select proper therapeutic drugs in individual cancer patients. Ovarian and breast cancer patients carrying germline mutations in BRCA1 or BRCA2 genes are often sensitive to DNA damaging......-type BRCA1 and BRCA2 genes. These results suggest that in cancers with DNA repair deficiency caused by functional BRCA loss, higher versus lower Nmut may reflect the status of deficiency or rescue by alternative mechanism(s) for DNA repair, with lower Nmut predicting for resistance to DNA-damaging drugs in...... drugs and relative to non-mutation carriers present a favorable clinical outcome following therapy. Genome sequencing studies have shown a high number of mutations in the tumor genome in patients carrying BRCA1 or BRCA2 mutations (mBRCA). The present study used exome-sequencing and SNP 6 array data of...

    Full Text Available Some literature suggests that outcomes of CAP in patients with solid tumor without neutropenia may be better than in cancer patients with neutropenia. In order to investigate the role of neutrophils in this population, we retrospectively analyzed consecutive patients with CAP admitted to 3 tertiary care hospitals from 01/2001 through 12/2005. HIV patients were excluded. A total of 993 patients were classified as follows: Group 1: no active cancer; Group 2: solid cancer without neutropenia; Group 3: solid cancer without neutropenia or hematologic malignancy. Age, Pneumonia Severity Index (PSI, overall mortality, time to reach clinical stability (TCS and length of stay in hospital (LOS are summarized in the table. No significant differences were found for any of the outcomes between group 2 and 3. Our results suggest that physicians should aggressively manage cancer patients with CAP, regardless of the neutrophil count.

    Objective:XRCC1 polymorphism is a research hotpot in individual treatment for non-small cell lung cancer (NSCLC).To obtain the association between XRCC1 polymorphism and clinical outcome of platinum-based treatment for NSCLC,a meta-analysis was conducted.Methods:Databases including PubMed,Embase,Cochrane,and Chinese National Knowledge Infrastructure (CNKI) were searched for publications that met the inclusion criteria.A fixed effect model was used to estimate pooled odds ratio (OR) and hazard ratio (HR) with 95% confidence interval (CI) for the association between XRCC1 Arg399Gln and response or survival of platinum-based treatment for advanced NSCLC.A chi-squared-based Q-test was used to test the heterogeneity hypothesis.Egger's test was used to check publication bias.Results:Seventeen published case-control studies that focus on the association between XRCC1 Arg399GIn and response or survival of platinum-based treatment for advanced NSCLC in 2 256 subjects were included in this meta-analysis,of whom 522 were AA genotypes (23.2% frequency),916 AG genotypes (40.6% frequency),and 818 GG genotypes (36.2% frequency).The overall response rate (ORR) was 45.2% (110/243) for AA genotype patients,29.9% for AG genotype (73/244),and 30.7% for GG genotype (124/403).The heterogeneity test did not show any heterogeneity and the Egger's test did not reveal an obvious publication bias among the included studies.The meta-analysis indicated that AA genotype patients presented higher response rates toward platinum drug treatment compared with G model (GG+GA) patients (GG vs.AA model:OR=0.489,95% CI 0.266-0.900,P=0.021;AG vs.AA model:OR=0.608,95% CI 0.392-0.941,P=0.026; GA+AA vs.GG model:OR=1.259,95% CI 0.931-1.701,P=0.135; GG+GA vs.AA model:OR=0.455,95% CI 0.313-0.663,P=0.0001).However,no evidence validates XRCC1 associates with the survival following platinum drug therapy.Conclusions:Our meta-analysis suggested that XRCC1 Arg399GIn is related with the

  18. Rectal cancer treatment and outcome in the elderly: an audit based on the Swedish rectal cancer registry 1995–2004

    International Nuclear Information System (INIS)

    Limited information is available regarding the effect of age on choice of surgical and oncological treatment for rectal cancer. The objective of this study was to assess the influence of age on treatment and outcome of rectal cancer. We utilized data in the Swedish Rectal Cancer Registry (SRCR) from patients treated for rectal cancer in Sweden in 1995–2004. A total of 15,104 patients with rectal cancer were identified, 42.4% of whom were 75 years or older. Patients ≥75 years were less likely to have distant metastases than younger patients (14.8% vs. 17.8%, P < 0.001), and underwent abdominal tumor resection less frequently (68.5% vs. 84.4%, P < 0.001). Of 11,725 patients with abdominal tumor resection (anterior resection [AR], abdominoperineal excision [APE], and Hartmann's procedure [HA]), 37.4% were ≥75 years. Curative surgery was registered for 85.0% of patients ≥ 75 years and for 83.9% of patients < 75 years, P = 0.11. Choice of abdominal operation differed significantly between the two age groups for both curative and non-curative surgery, The frequency of APE was similar in both age groups (29.5% vs. 28.6%), but patients ≥75 years were more likely to have HA (16.9% vs. 4.9%) and less likely to have preoperative radiotherapy (34.3vs. 67.2%, P < 0.001). The relative survival rate at five years for all patients treated with curative intent was 73% (70–75%) for patients ≥75 years and 78% (77–79%) for patients < 75 years of age. Local recurrence rate was 9% (8–11%) for older and 8% (7–9%) for younger patients. Treatment of rectal cancer is influenced by patient's age. Future studies should include younger and older patients alike to reveal whether or not age-related differences are purposive. Local recurrence following surgery for low tumors and quality of life aspects deserve particular attention

    Purpose Brain metastasis is the most common complication of brain cancer; nevertheless, primary lung cancer accounts for approximately 20%–40% of brain metastases cases. Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC) in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases ...

    2011-12-01

    Full Text Available Despite treatment with radical cystectomy and pelvic lymph node dissection, muscle invasive bladder cancer has a relapse rate of 50%. Patients can develop regionally advanced or metastatic disease that ultimately leads to death. The addition of neoadjuvant or adjuvant chemotherapy to reduce the risk of relapse and death has been extensively studied over the past two decades. Two contemporary trials coupled with a recent meta-analysis evaluating neoadjuvant chemotherapy demonstrated a modest but real improvement in overall survival. This has made neoadjuvant chemotherapy a standard of care. Clinical trials evaluating adjuvant chemotherapy in patients with high-risk disease have been plagued with statistical flaws and have, therefore, been unable to define the survival impact of this approach. It is hoped that ongoing adjuvant trials that are powered to detect small but meaningful clinical differences will clarify the benefit of chemotherapy after cystectomy. Since there are theoretical advantages and disadvantages to each of these approaches, both are widely used in North America. The evidence behind each approach and potential future developments in this field will be described.

    Full Text Available This study examined the effect of surgeons’ volume on outcomes in lung surgery: lobectomies and wedge resections. Additionally, the effect of video-assisted thoracoscopic surgery (VATS on cost, utilization, and adverse events was analyzed. The Premier Hospital Database was the data source for this analysis. Eligible patients were those of any age undergoing lobectomy or wedge resection using VATS for cancer treatment. Volume was represented by the aggregate experience level of the surgeon in a six-month window before each surgery. A positive volume-outcome relationship was found with some notable features. The relationship is stronger for cost and utilization outcomes than for adverse events; for thoracic surgeons as opposed to other surgeons; for VATS lobectomies rather than VATS wedge resections. While there was a reduction in cost and resource utilization with greater experience in VATS, these outcomes were not associated with greater experience in open procedures.

  5. Survival outcomes in patients with cervical cancer after inclusion of PET/CT in staging procedures

    International Nuclear Information System (INIS)

    In cancer of the uterine cervix, lymph node metastases are associated with a poor prognosis. Even so, the International Federation of Gynecology and Obstetrics (FIGO) does not take into account diagnostic results of methods such as PET/CT, since these are not readily available everywhere. As undetected lymph node metastases can lead to undertreatment, any difference in the underlying prevalence of false-negative scans between CT and PET/CT may be reflected in treatment outcomes. This study investigated survival outcomes in node-negative patients before and after the introduction of PET/CT. This was a single-institution retrospective analysis of 301 patients with a histopathological diagnosis of cervical cancer. The patients were receiving chemoradiotherapy with curative intent according to the standard protocol of the department for patients without lymph node metastases as assessed by pretreatment CT or PET/CT. Patients were stratified into two groups: PET/CT and non-PET/CT. Patient characteristics and treatment outcomes were acquired from the treatment database. Significant differences of 23 % (95 % CI 17 - 29 %), 19 % (95 % CI 13 - 25 %) and 12 % (95 % CI 6 - 18 %) in 5-year overall, disease-free and disease-specific survival, respectively, were observed between the two patient groups. The difference remained significant in univariate and multivariate analyses of overall survival (hazard ratio 0.61, 95 % CI 0.42 - 0.89; p = 0.010), including age, FIGO stage, performance status, BMI, and histopathology. Inclusion of PET/CT in the preradiotherapy diagnostic protocol may lead to nodal stage migration not reflected in the FIGO stage. It was found to be a significant covariate, and could lead to selection bias that needs to be taken into account when designing and reporting on clinical trials. (orig.)

  7. Microsatellite Instability Predicts Clinical Outcome in Radiation-Treated Endometrioid Endometrial Cancer

    International Nuclear Information System (INIS)

    Purpose: To elucidate whether microsatellite instability (MSI) predicts clinical outcome in radiation-treated endometrioid endometrial cancer (EEC). Methods and Materials: A consecutive series of 93 patients with EEC treated with extrafascial hysterectomy and postoperative radiotherapy was studied. The median clinical follow-up of patients was 138 months, with a maximum of 232 months. Five quasimonomorphic mononucleotide markers (BAT-25, BAT-26, NR21, NR24, and NR27) were used for MSI classification. Results: Twenty-five patients (22%) were classified as MSI. Both in the whole series and in early stages (I and II), univariate analysis showed a significant association between MSI and poorer 10-year local disease-free survival, disease-free survival, and cancer-specific survival. In multivariate analysis, MSI was excluded from the final regression model in the whole series, but in early stages MSI provided additional significant predictive information independent of traditional prognostic and predictive factors (age, stage, grade, and vascular invasion) for disease-free survival (hazard ratio [HR] 3.25, 95% confidence interval [CI] 1.01-10.49; p = 0.048) and cancer-specific survival (HR 4.20, 95% CI 1.23-14.35; p = 0.022) and was marginally significant for local disease-free survival (HR 3.54, 95% CI 0.93-13.46; p = 0.064). Conclusions: These results suggest that MSI may predict radiotherapy response in early-stage EEC.

    Full Text Available Abstract Background Synuclein gamma (SNCG, initially identified as a breast cancer specific gene, is aberrantly expressed in many different malignant tumors but rarely expressed in matched nonneoplastic adjacent tissues. In this study, we investigated the prognostic potential of SNCG in colon cancer particularly in the patients with normal carcinoembryonic antigen (CEA levels. Methods SNCG levels were assessed immunohistochemically in cancer tissues from 229 colon adenocarcinoma patients with a mean follow-up of 44 months. Correlations between SNCG levels and clinicopathologic features, preoperative serum CEA level, and clinical outcome were analyzed statistically using SPSS. Results SNCG levels in colon adenocarcinoma were closely associated with intravascular embolus and tumor recurrence but independent of preoperative serum CEA levels. SNCG expression was an independent prognostic factor of a shorter disease-free survival (DFS and overall survival (OS (P P = 0.001, P = 0.001, 0.002 for 97 patients with normal preoperative serum CEA level. Conclusions Our results suggest for the first time that SNCG is a new independent predicator for poor prognosis in patients with colon adenocarcinoma, including those with normal CEA levels. Combination of CEA with SNCG improves prognostic evaluation for patients with colon adenocarcinoma.

    Full Text Available Length of survival of cancer patients is an important indicator for knowing the outcome of treatment in any study. Epidemiological features and biological profile of breast cancer appear to be different in developing countries as compared to Western countries. Knowing the factors that influence survival rates among women with breast cancer may help define early detection actions, and improve treatment and care proposals in all the areas of health. Therefore, this study aims to identify, the publications defining the factors influencing survival for women with breast cancer in India. PUBMED database was searched from January 1990 to April 2016, using the key words Breast cancer, breast cancer outcome and Survival and their corresponding Mesh terms were used in combination with Boolean operators like OR, AND. Five year overall survival rate of breast cancer in India ranged from 40-62%. The results from 16 publications showed that survival of breast cancer varies widely depending on number of factors like age, stage at diagnosis, marital status, educational level, hormonal status, clinical extent of disease and treatment. The publications that make up this review present contributing factors that affect the survival rate of women with breast cancer in India. This information on survival studies can pinpoint the lacunae in treatment modalities and can guide us to do basic and translational research so the preventive strategies can be implemented.

    2003-08-01

    Full Text Available Radical prostatectomy continues to play a central role in the management of localized prostate cancer. The majority of patients diagnosed with prostate cancer will undergo radical prostatectomy. A decrease in the morbidity of this surgical procedure has been accomplished through an improved understanding of pelvic anatomy and a greater understanding of the natural history of prostate cancer. Recently, minimally invasive techniques have been applied to radical prostatectomy (laparoscopic prostatectomy in order to further decrease the morbidity of this operation. What remains to be determined is whether this approach confers the same long term surgical outcomes as the open approach. One method which offers known long term outcomes coupled with decreased morbidity is the radical perineal prostatectomy. The purpose of this paper is to review the criteria for patient selection as well as outcomes of the radical perineal prostatectomy.

    Purpose: To evaluate cosmetic outcome and its association with breast wound seroma after breast-conserving surgery (BCS) with targeted intraoperative radiation therapy (tIORT) boost for early breast cancer. Methods and Materials: An analysis of a single-arm prospective study of 55 patients with early breast cancer treated with BCS and tIORT boost followed by conventional whole breast radiation therapy (WBRT) between August 2003 and January 2006 was performed. A seroma was defined as a fluid collection at the primary tumor resection site identified clinically or radiologically. Cosmetic assessments using the European Organization for Research and Treatment of Cancer rating system were performed at baseline before BCS and 30 months after WBRT was completed. Results: Twenty-eight patients (51%) developed a seroma, with 18 patients (33%) requiring at least 1 aspiration. Tumor location was significantly associated with seroma formation (P=.001). Ten of 11 patients with an upper inner quadrant tumor developed a seroma. Excellent or good overall cosmetic outcome at 30 months was observed in 34 patients (62%, 95% confidence interval 53%-80%). Seroma formation was not associated with the overall cosmetic result (P=.54). Conclusion: BCS with tIORT boost followed by WBRT was associated with an acceptable cosmetic outcome. Seroma formation was not significantly associated with an adverse cosmetic outcome.

  15. Outcome of fertility preserving surgery in early stage ovarian cancer

    International Nuclear Information System (INIS)

    Aim: To assess the role of fertility preserving surgery in treatment of patients with stage I A, G1 or G2 ovarian carcinoma without adjuvant chemotherapy. Patients and methods: From 2006 to 2008, a prospective non-randomized study recruited 150 women, with suspicious early malignant ovarian mass. Results: Among the 150 explored patients, only 43 (28.6%) patients underwent exploration. Only 32/150 (21.3%) patients had proven stage IA, either G1 or G2, epithelial ovarian cancer. Among the 32 patients, 22 (68.7%) patients were nullipara while 10 (32.1%) had one child. All patients had unilateral tumors; 26 (81.25%) patients had G1 and 6 (18.75%) patients had G2 tumors; 24/32 (75.0%) tumors were serous, 6/32 (18.7%) were mucinous and 2/32 (6.2%) were endometrioid, and none was clear cell type. The median follow up period was 58.5 months (ranged: 48- 72 months). Two patients (6.7%) were lost during follow up; data will be presented for the remaining 30 patients. One patient, at 27th month of follow up, had open abdominal exploration to investigate abnormal pelvic mass on routine ultrasound follow up examination. Frozen section revealed recurrent invasive mucinous tumor. She underwent radical surgery with pelvic and para-aortic lymph node dissection, followed by adjuvant chemotherapy, and remained free of disease, for the remaining 29 months of the follow up period. Neither distant metastases nor mortality were reported among our patients.Conclusion: Fertility preserving surgery can be considered a safe treatment strategy in patients with stage IA, G1 of (32 ovarian carcinoma Conclusion: Fertility preserving surgery can be considered a safe treatment strategy in patients with stage IA, G1 of G2 ovarian carcinoma

    Background Hypnosis is defined as "as an interaction in which the hypnotist uses suggested scenarios ("suggestions") to encourage a person's focus of attention to shift towards inner experiences". Aim of the work The focus of this review is to summarize the findings of controlled outcome studies investigating the potential of clinical hypnosis in pediatric populations. We will examine the following themes: anesthesia, acute and chronic pain, chemotherapy-related distress, along with other specific medical issues. Results Hypnosis is an effective method to reduce pain and anxiety before, during and after the administration of anesthetics, during local dental treatments, invasive medical procedures and in burn children. Hypnosis can be successfully used to manage recurrent headaches, abdominal pain, irritable bowel syndrome and chemotherapy-related distress. Hypnosis has an important role in managing symptoms and improving the quality of life of children suffering from asthma and cystic fibrosis and in facilitating the treatment of insomnia in school-age children. Finally, hypnosis can be effectively used for the treatment of some habitual disorders such as nocturnal enuresis and dermatologic conditions, including atopic dermatitis and chronic eczema Conclusions Clinical hypnosis seems to be a useful, cheap and side-effects free tool to manage fear, pain and several kinds of stressful experiences in pediatric populations. Children who receive self-hypnosis trainings achieve significantly greater improvements in their physical health, quality of life, and self-esteem. PMID:24165457

    Ovarian cancer is one of the leading female cancers in the United States. Challenges remain in early diagnosis of this deadly disease. Matrix metalloproteinases (MMPs) family genes are paradoxically involved in cancer promotion and suppression. We hypothesize that genetic variants in MMP genes are associated with ovarian cancer development, so they could be potential markers for ovarian cancer diagnosis and prognosis. In this study of 417 ovarian cancer cases and 417 healthy controls, we genotyped a comprehensive panel of 266 single nucleotide polymorphisms (SNPs) in 23 MMP genes and analysed their associations with ovarian cancer risk, overall survival and treatment response in ovarian cancer cases who received platinum-based chemotherapy with surgery. In the analysis on 339 Caucasian cases and 349 Caucasian controls, 4 SNPs were significantly associated with cancer risk. The most significant association was observed for rs2292730 (OR = 2.03, 95% CI = 1.39-2.96, P = 0.0002). Classification and regression tree analysis identified four terminal nodes with differential risk of ovarian cancer. Thirty-four SNPs were significantly associated with overall survival and four of which showed significant association with response to chemotherapy. Unfavourable genotype analysis of top SNPs on overall risk of death showed significant gene-dosage effect, survival tree analysis differentiated patients into distinct risk groups based on their genetic profiles with median survival times (MSTs) ranging from 17.7 to 151.7 months. In conclusion, our results suggest that genetic variants in MMP pathway genes may modulate the risk and clinical outcomes of ovarian cancer, both individually and jointly. PMID:25867973

    Full Text Available Lymphedema is a common complication of cancer therapeutics; its prevalence, treatment outcomes, and costs have been poorly defined. The objective of this study was to examine lymphedema prevalence among cancer survivors and to characterize changes in clinical outcomes and costs associated with a defined therapeutic intervention (use of a pneumatic compression devices [PCD] in a representative, privately insured population.Retrospective analysis of de-identified health claims data from a large national insurer for calendar years 2007 through 2013. Patients were required to have 12 months of continuous insurance coverage prior to PCD receipt (baseline, as well as a 12-month follow-up period. Analyses were performed for individuals with cancer-related lymphedema (n = 1,065. Lymphedema prevalence was calculated: number of patients with a lymphedema claim in a calendar year divided by total number of enrollees. The impact of PCD use was evaluated by comparing rates of a pre-specified set of health outcomes and costs for the 12 months before and after, respectively, PCD receipt. Lymphedema prevalence among cancer survivors increased from 0.95% in 2007 to 1.24% in 2013. PCD use was associated with decreases in rates of hospitalizations (45% to 32%, p<0.0001, outpatient hospital visits (95% to 90%, p<0.0001, cellulitis diagnoses (28% to 22%, p = 0.003, and physical therapy use (50% to 41%, p<0.0001. The average baseline health care costs were high ($53,422 but decreased in the year after PCD acquisition (-$11,833, p<0.0001.Lymphedema is a prevalent medical condition that is often a defining attribute of cancer survivorship. The problem is associated with high health care costs; Treatment (in this instance, use of PCD is associated with significant decreases in adverse clinical outcomes and costs.

Out of 173 patients, 38 patients had recurrent tumors after microsurgical resection and whole brain radiotherapy (WBT. Results: GKRS in MBTs metastasized from lung carcinoma showed significant variations in tumor growth control (decreased in 79 [45.7%] patients, arrested growth in 54 [31.2%] patients, and increased tumor size in 40 [23.1%] patients. The median survival in the study population was 14 months. Overall survival after 3 years was 25%, whereas progression-free survival after 3 years was 45%. The predictive factors for improving survival in the patients with MBTs were recursive partitioning analysis (RPA class I (P = 0.005, absence of hydrocephalus (P = 0.001, Karnofsky performance scale (KPS >70 (P = 0.007, age ≤65 (P = 0.041, tumor size ≤3 cm (P = 0.023, controlled primary tumor (P = 0.049, and single number of MBTS (P = 0.044. Conclusion: Long-term follow-up revealed that GKRS offers a high rate of tumor control and good overall survival period in both new and recurrent patients with MBTs originating from lung carcinoma. Thus, GKRS is an effective treatment option for new patients with MBTs from lung cancer, as well as an adjuvant therapy in patients with recurrent MBTs derived from lung cancer.

  11. Techniques and Outcome of Surgery for Locally Advanced and Local Recurrent Rectal Cancer.

    Science.gov (United States)

    Renehan, A G

    2016-02-01

    Locally advanced primary rectal cancer is variably defined, but generally refers to T3 and T4 tumours. Radical surgery is the mainstay of treatment for these tumours but there is a high-risk for local recurrence. National Institute for Health and Care Excellence (2011) guidelines recommend that patients with these tumours be considered for preoperative chemoradiotherapy and this is the starting point for any discussion, as it is standard care. However, there are many refinements of this pathway and these are the subject of this overview. In surgical terms, there are two broad settings: (i) patients with tumours contained within the mesorectal envelope, or in the lower rectum, limited to invading the sphincter muscles (namely some T2 and most T3 tumours); and (ii) patients with tumours directly invading or adherent to pelvic organs or structures, mainly T4 tumours - here referred to as primary rectal cancer beyond total mesorectal excision (PRC-bTME). Major surgical resection using the principles of TME is the mainstay of treatment for the former. Where anal sphincter sacrifice is indicated for low rectal cancers, variations of abdominoperineal resection - referred to as tailored excision - including the extralevator abdominoperineal excision (ELAPE), are required. There is debate whether or not plastic reconstruction or mesh repair is required after these surgical procedures. To achieve cure in PRC-bTME tumours, most patients require extended multivisceral exenterative surgery, carried out within specialist multidisciplinary centres. The surgical principles governing the treatment of recurrent rectal cancer (RRC) parallel those for PRC-bTME, but typically only half of these patients are suitable for this type of major surgery. Peri-operative morbidity and mortality are considerable after surgery for PRC-bTME and RRC, but unacceptable levels of variation in clinical practice and outcome exist globally. To address this, there are now major efforts to standardise

  13. Defining an outcomes management program for definitive irradiation of prostate cancer: preliminary considerations

    International Nuclear Information System (INIS)

    PURPOSE: The advent of managed medical care presents challenges to health care providers who strive to maintain a high quality of patient care at a reasonable cost. The goals of clinical guidelines and paths are to improve the quality of patient care by using outcomes to redefine the path and to eliminate ineffective steps in the clinical algorithm. The purpose of the current endeavor was to systematically develop a clinical pathway for the radiation therapy of prostate cancer which can serve as 1) a measurement tool of operational variables such as cost and utilization, 2) a treatment tool to measure satisfaction and toxicity, 3) a research framework from which questions of efficacy can be investigated. METHODS: An initial path was constructed by the physicians based on recommendations from consensus conference of the Patterns of Care Study (PCS), and the Radiation Therapy Oncology Group (RTOG). The program was initiated by a core group of 2 attending radiation oncologists, a radiation physicist, a clinical nurse specialist, a dosimetrist, a simulation technologist, a treatment technologist, and a medical social worker. These data served as a baseline from which clinical pathway development could begin using the method of Continuous Quality Improvement (CQI) as described by Berwick (New Engl J Med 320: 53, 1989). Following the creation of a draft path, the document was circulated to other staff members of the team. Simultaneously, the Clinical Financial Management System (Transition Systems Incorporated, Boston, MA) was applied to departmental and institutional records to determine treatment patterns, utilization, toxicity, and cost for prostate cancer patients irradiated between July 1, 1995 and December 31, 1995. The aforementioned staff team as well as a seven person patient group were queried by a CQI facilitator to identify process and quality factors to be included in the clinical path. RESULTS: During the period of study, 51 patients were definitively

    Active surveillance (AS) has emerged as a standard management option for men with very low-risk and low-risk prostate cancer, and contemporary data indicate that use of AS is increasing in the United States and abroad. In the favorable-risk population, reports from multiple prospective cohorts indicate a less than 1% likelihood of metastatic disease and prostate cancer-specific mortality over intermediate-term follow-up (median 5 to 6 years). Higher-risk men participating in AS appear to be at increased risk of adverse outcomes, but these populations have not been adequately studied to this point. Although monitoring on AS largely relies on serial prostate biopsy, a procedure associated with significant morbidity, there is a need for improved diagnostic tools for patient selection and monitoring. Revisions from the 2014 International Society of Urologic Pathology consensus conference have yielded a more intuitive reporting system and detailed reporting of low-intermediate grade tumors, which should facilitate the practice of AS. Meanwhile, emerging modalities such as multiparametric magnetic resonance imaging and tissue-based molecular testing have shown prognostic value in some populations. At this time, however, these instruments have not been sufficiently studied to consider their routine, standardized use in the AS setting. Future studies should seek to identify those platforms most informative in the AS population and propose a strategy by which promising diagnostic tools can be safely and efficiently incorporated into clinical practice.

  15. Interrogating differences in expression of targeted gene sets to predict breast cancer outcome

    International Nuclear Information System (INIS)

    Genomics provides opportunities to develop precise tests for diagnostics, therapy selection and monitoring. From analyses of our studies and those of published results, 32 candidate genes were identified, whose expression appears related to clinical outcome of breast cancer. Expression of these genes was validated by qPCR and correlated with clinical follow-up to identify a gene subset for development of a prognostic test. RNA was isolated from 225 frozen invasive ductal carcinomas,and qRT-PCR was performed. Univariate hazard ratios and 95% confidence intervals for breast cancer mortality and recurrence were calculated for each of the 32 candidate genes. A multivariable gene expression model for predicting each outcome was determined using the LASSO, with 1000 splits of the data into training and testing sets to determine predictive accuracy based on the C-index. Models with gene expression data were compared to models with standard clinical covariates and models with both gene expression and clinical covariates. Univariate analyses revealed over-expression of RABEP1, PGR, NAT1, PTP4A2, SLC39A6, ESR1, EVL, TBC1D9, FUT8, and SCUBE2 were all associated with reduced time to disease-related mortality (HR between 0.8 and 0.91, adjusted p < 0.05), while RABEP1, PGR, SLC39A6, and FUT8 were also associated with reduced recurrence times. Multivariable analyses using the LASSO revealed PGR, ESR1, NAT1, GABRP, TBC1D9, SLC39A6, and LRBA to be the most important predictors for both disease mortality and recurrence. Median C-indexes on test data sets for the gene expression, clinical, and combined models were 0.65, 0.63, and 0.65 for disease mortality and 0.64, 0.63, and 0.66 for disease recurrence, respectively. Molecular signatures consisting of five genes (PGR, GABRP, TBC1D9, SLC39A6 and LRBA) for disease mortality and of six genes (PGR, ESR1, GABRP, TBC1D9, SLC39A6 and LRBA) for disease recurrence were identified. These signatures were as effective as standard clinical

    The number of operations on elderly colorectal cancer (CRC) patients has increased with the aging of the population. The aim of this study was to evaluate surgical outcomes in elderly patients who underwent laparoscopic or open surgery for CRC. We analyzed the data of 280 patients aged 80 or over who underwent surgery for CRC between January 2001 and December 2010. Seventy-one pairs were selected after propensity score matching for laparoscopic or open surgery. Operative time, return to normal bowel function, length of hospital stay, postoperative complications, overall survival (OS), recurrence-free survival (RFS), and prognostic factors affecting survival were investigated. In matched cohorts, operative time in the laparoscopic group was longer than in the open group (P surgery for CRC in elderly patients may be safe and feasible, with better short-term outcomes. OS and RFS, however, were not different in both groups. PMID:26923309

  18. Cancer-affine radiopharmaceuticals for the study of biochemical nature of cancer and in the early diagnosis and follow-up of cancer and its systemic therapy

    International Nuclear Information System (INIS)

    Cancer patient needs less diagnosis but an effective therapy. The systemic nature of cancer, often right from its inception, requires systemic therapy with cancer-affine radiopharmaceuticals which contain radionuclide species recognizing both the primary and secondary cancers which have generally different biochemical properties. Cancers may be classified into two groups: I. CATIONIC COMPLEX-AFFINE TUMOURS; Lung cancer, thyroid cancer, primary breast cancer, renal cell carcinoma, bone metastases from anionic complex-affine cancers, ...; II. ANIONIC COMPLEX-AFFINE TUMOURS; Primary prostate cancer, melanoma, hepatocellular carcinoma, osteosarcoma, Ewing's sarcoma, bone metastases from cationic complex-affine cancer. With cancer-affine citratogallate-67 complexes we have diagnosed and followed up, and with citratoyttrate-90 complexes we have treated advanced breast, prostate, renal cell cancer patients. The patient preparation by advising to avoid cancer risk factors and to take cancer preventing and radiopharmaceutical stabilizing diets during diagnosis and therapy have given better results. Friendliness, caring visits and telephone calls from the therapist group help to obtain better outcomes of the diagnosis, and mainly of the therapy. The complexes of these radionuclides with other chelating agents EDTA and DPTA are expected to give better images and cure of advanced cancer patients. Cancer-affine formulations of Tc-99m(V), Re-186(V) and Re-188(V)-DMSA are being studied for their future use in early diagnosis and follow-up, and for the systemic therapy of cancer which will show affinity for them.

    Bhatia, Smita

    2011-10-01

    Clear and unambiguous associations have been established between therapeutic exposures and specific complications. However, considerable interindividual variability is observed in the risk of developing an outcome for a given therapeutic exposure. Genetic predisposition and especially its interaction with therapeutic exposures can potentially exacerbate the toxic effect of treatment on normal tissues and organ systems, and can possibly explain the interindividual variability. This article provides a brief overview of the current knowledge about the role of genomic variation in the development of therapy-related complications. Relatively common outcomes with strong associations with therapeutic exposures, including cardiomyopathy, obesity, osteonecrosis, ototoxicity, and subsequent malignancies are discussed here. To develop a deeper understanding of the molecular underpinnings of therapy-related complications, comprehensive and near-complete collection of clinically annotated samples is critical. Methodologic issues such as study design, definition of the endpoints or phenotypes, identification of appropriate and adequately sized study population together with a reliable plan for collecting and maintaining high-quality DNA, and selection of an appropriate approach or platform for genotyping are also discussed. Understanding the etiopathogenetic pathways that lead to the morbidity is critical to developing targeted prevention and intervention strategies, optimizing risk-based health care of cancer survivors, thus minimizing chronic morbidities and improving quality of life.

    International Nuclear Information System (INIS)

    Background and purpose: To assess the completeness and accuracy of stage and outcome data in the Anthology of Outcomes (AOs), a prospective point-of-care physician-collected electronic data system for patients at Princess Margaret Hospital. Material and methods: A random sample of 10% of the AO cases registered between July 2003 and December 2005 was drawn. An audit was conducted of the AO data compared with chart review and cancer registry. Results: The AO system was applied first to a head and neck (HN) cancer patient cohort. From 1152 HN cases, 120 were audited. TNM stage was recorded in all cases. Discrepancy was found between the AO and primary data sources in 3-13% of cases. Physician review showed a 3% error rate in overall stage recorded in the AO. Sixty-two outcomes in 43 patients were found on chart review. No outcomes were incorrectly recorded in the AO. Nineteen (31%) outcomes in 17 patients were missed in the AO. Conclusions: Our experience has demonstrated the feasibility of real-time outcome recording at point-of-care. New processes needed to improve the completeness of capture of patient outcomes in the AO have more recently been introduced. This successful system has been expanded to other disease sites.

    In the United States, Black men are at higher risk than White men for lung cancer mortality whereas rates are comparable between Black and White women. This article draws from empirical work in lung cancer, mental health, and health disparities to highlight that race and depression may overlap in predicting lower treatment access and utilization and poorer quality of life among patients. Racial barriers to depression identification and treatment in the general population may compound these risks. Prospective data are needed to examine whether depression plays a role in racial disparities in lung cancer outcomes. PMID:23514250

  4. Clinical features, outcome and risk factors in cervical cancer patients after surgery for chronic radiation enteropathy

    International Nuclear Information System (INIS)

    Radical hysterectomy and radiotherapy have long been mainstays of cervical cancer treatment. Early stage cervical cancer (FIGO stage IB1–IIA) is traditionally treated using radical surgery combined with radiotherapy, while locally advanced cervical cancer is treated using radiotherapy alone or chemoradiotherapy. In this retrospective study, we describe and analyse the presenting clinical features and outcomes in our cohort and evaluate possible risk factors for postoperative morbidity in women who underwent surgery for chronic radiation enteropathy (CRE). One hundred sixty-six eligible cervical cancer patients who underwent surgery for CRE were retrospectively identified between September 2003 and July 2014 in a prospectively maintained database. Among them, 46 patients received radical radiotherapy (RRT) and 120 received radical surgery plus radiotherapy (RS + RT). Clinical features, postoperative morbidity and mortality, and risk factors for postoperative morbidity were analysed. RS + RT group patients were more likely to present with RTOG/EORTC grade III late morbidity (76.1 % vs 92.5 %; p = 0.004), while RRT group patients tended to show RTOG/EORTC grade IV late morbidity (23.9 % vs 7.5 %; p = 0.004). One hundred forty patients (84.3 %) were treated with aggressive resection (anastomosis 57.8 % and stoma 26.5 %). Overall and major morbidity, mortality and incidence of reoperation in the RRT and RS + RT groups did not differ significantly (63 % vs 64.2 % [p = 1.000], 21.7 % vs 11.7 % [p = 0.137], 6.5 % vs 0.8 % [p = 0.065] and 6.5 % vs 3.3 % [p = 0.360], respectively). However, incidence of permanent stoma and mortality during follow-up was higher in the RRT group than in the RS + RT group (44.2 % vs 12.6 % [p = 0.000] and 16.3 % vs 3.4 % [p = 0.004], respectively). In multivariate analysis, preoperative anaemia was significantly associated with overall morbidity (p = 0.015), while severe intra-abdominal adhesion (p = 0.017), ASA grades III–V (P = 0

  5. Comparison of mortality outcomes after radical prostatectomy versus radiotherapy in patients with localized prostate cancer. A population-based analysis

    International Nuclear Information System (INIS)

    The objectives of this study were to compare the mortality outcomes of radical prostatectomy and radiotherapy as treatment modalities for patients with localized prostate cancer. Our cohort consisted of 68 665 patients with localized prostate cancer, treated with radical prostatectomy or radiotherapy, between 1992 and 2005. Propensity-score matching was used to minimize potential bias related to treatment assignment. Competing-risks analyses tested the effect of treatment type on cancer-specific mortality, after accounting for other-cause mortality. All analyses were stratified according to prostate cancer risk groups, baseline Charlson Comorbidity Index and age. For patients treated with radical prostatectomy versus radiotherapy, the 10-year cancer-specific mortality rates were 1.4 versus 3.9% in low-intermediate risk prostate cancer and 6.8 versus 11.5% in high-risk prostate cancer, respectively. Rates were 2.4 versus 5.9% in patients with Charlson Comorbidity Index of 0, 2.4 versus 5.1% in patients with Charlson Comorbidity Index of 1, and 2.9 versus 5.2% in patients with Charlson Comorbidity Index of ≥2. Rates were 2.1 versus 5.0% in patients aged 65-69 years, 2.8 versus 5.5% in patients aged 70-74 years, and 2.9 versus 7.6% in patients aged 75-80 years (all P<0.001). At multivariable analyses, radiotherapy was associated with less favorable cancer-specific mortality in all categories (all P<0.001). Patients treated with radical prostatectomy fare substantially better than those treated with radiotherapy. Patients with high-risk prostate cancer benefit the most from radical prostatectomy. Conversely, the lowest benefit was observed in patients with low-intermediate risk prostate cancer and/or multiple comorbidities. An intermediate benefit was observed in the other examined categories. (author)

    Full Text Available Anna Falanga, Alfonso Vignoli, Erika Diani, Marina MarchettiDivision of Immunohematology and Transfusion Medicine, Ospedali Riuniti, Bergamo, ItalyAbstract: Patients with cancer are at high risk of developing venous thromboembolism (VTE, including deep venous thrombosis and pulmonary embolism. Compared to non-cancer patients, VTE in cancer is more frequently associated with clinical consequences, including recurrent VTE, bleeding, and an increase in the risk of death. Low-molecular-weight heparins (LMWHs are commonly recommended for the prevention and treatment of VTE in cancer patients because of their favorable risk-to-benefit profile. Indeed, compared with vitamin K antagonists, LMWHs are characterized by a reduced need for coagulation monitoring, few major bleeding episodes, and once-daily dosing, which make these drugs more suitable in the cancer setting. Guidelines have been published recently with the aim to improve the clinical outcomes in cancer patients at risk of VTE and its complications. Coagulation activation in cancer may have a role not only in thrombosis but also in tumor growth and dissemination. Hence, inhibition of fibrin formation has been considered a possible tool against the progression of malignant disease. Clinical studies show that anticoagulant drugs may have a beneficial effect on survival in cancer patients, with a major role for LMWHs. Recently a number of prospective randomized clinical trials to test LMWHs to improve cancer survival as a primary endpoint in cancer patients have been conducted. Although the results are controversial, the interest in this research area remains high.Keywords: venous thromboembolism, VTE, LMWH

  7. Cell Cycle Inhibitors and Outcome after Radiotherapy in Bladder Cancer Patients

    International Nuclear Information System (INIS)

    The aim of this study was to correlate the expression of cell cycle inhibitors with outcome of patients with muscle-invasive bladder cancer treated with preoperative radiotherapy (46 Gy/4-5 weeks or 20 Gy/1 week) and cystectomy. Patients with pT3b (n=42) or pT0 (n=17) were included in the study. Expression of p16INK4a and p27KIP1 was assessed immunohistochemically in pre-radiotherapy biopsies and cystectomy specimens. Previously reported results of p21CIP1 expression were also included. No difference in pretreatment protein expression was found between patients with pT0 and pT3b. Expression of p21CIP1 and p27KIP1 was lower in cystectomy specimens than in pretreatment biopsies. None of the proteins showed significant impact on survival when analysed separately. However, patients with tumours showing > 50% expression of p16INK4a, p21CIP1, or p27KIP1 displayed poorer cancer-specific survival rates compared with the remaining patients (p=0.025). This effect was more pronounced in patients receiving 46 Gy than in those receiving 20 Gy. In conclusion, low expression of cell cycle inhibitors is related to favourable survival after precystectomy radiotherapy

    Full Text Available Aim of the Study: Aim was to assess the clinical significance of the rate of tumor regression in carcinoma buccal mucosa undergoing radical radiotherapy. Materials and Methods: Sixty six patients were enrolled in the study with proven buccal cancers requiring radical radiotherapy, from 1990 to 1996. Radiotherapy was delivered using a combination of external beam and brachytherapy with preloaded cesium 137 needles. The response to the radiation was assessed at the completion of external beam radiation and 6 weeks after brachytherapy. An analysis correlating various parameters influencing the long term disease free survival and overall survival was done. Results: Response assessed at the end of external beam radiation correlated strongly with the overall survival and the disease free interval (P=0.000. No other factor influenced the survival. Conclusion: The rate of the tumor regression can predict the overall outcome in patients with buccal cancers treated with radiation. Completion of the planned course of radiation in patients who do not show a substantial reduction in size by 4.5 weeks of conventional radiation does not improve the results.

    Detoxification enzymes, especially glutathione S-transferase P1-1 (GSTP1-1), have been implicated in resistance to platinum-based chemotherapy. We studied GSTP1-1 levels in ovarian cyst fluid (oCF), obtained during surgery before chemotherapy, of patients with epithelial ovarian cancer and clinical outcomes were correlated. GSTP1-1 was determined by ELISA in oCF of 56 patients with epithelial ovarian cancer and 109 noncancer controls (21 borderline and 88 benign ovarian tumors). Differences in median GSTP1-1 between clinicopathologic subgroups were studied using Mann-Whitney U and Kruskal Wallis tests. Differences in disease-free (DFS) and overall survival (OS) between groups were analyzed by applying Kaplan-Meyer estimates and log-rank tests. Univariate and multivariate analysis were done using Cox proportional hazard model. Significantly higher levels of GSTP1-1 were found in the oCF of malignant (median, 383; range, 10-32,695 ng/mL) compared with benign (median, 20; range, 0-1,128 ng/mL) ovarian tumors (P or=Ic; n = 30), high GSTP1-1 levels were significantly associated with a poor DFS and OS (log-rank P = 0.047 and P = 0.033, respectively). International Federation of Gynaecologists and Obstetricians stage was the only independent predictor for DFS. GSTP1-1 was the only independent predictor for OS. PMID:19661073

    Purpose: We have previously reported that metabolic tumor volume (MTV) obtained from pretreatment {sup 18}F-fluorodeoxydeglucose positron emission tomography (FDG PET)/ computed tomography (CT) predicted outcome in patients with head-and-neck cancer (HNC). The purpose of this study was to validate these results on an independent dataset, determine whether the primary tumor or nodal MTV drives this correlation, and explore the interaction with p16{sup INK4a} status as a surrogate marker for human papillomavirus (HPV). Methods and Materials: The validation dataset in this study included 83 patients with squamous cell HNC who had a FDG PET/CT scan before receiving definitive radiotherapy. MTV and maximum standardized uptake value (SUV{sub max}) were calculated for the primary tumor, the involved nodes, and the combination of both. The primary endpoint was to validate that MTV predicted progression-free survival and overall survival. Secondary analyses included determining the prognostic utility of primary tumor vs. nodal MTV. Results: Similarly to our prior findings, an increase in total MTV of 17 cm{sup 3} (difference between the 75th and 25th percentiles) was associated with a 2.1-fold increase in the risk of disease progression (p = 0.0002) and a 2.0-fold increase in the risk of death (p = 0.0048). SUV{sub max} was not associated with either outcome. Primary tumor MTV predicted progression-free (hazard ratio [HR] = 1.94; p < 0.0001) and overall (HR = 1.57; p < 0.0001) survival, whereas nodal MTV did not. In addition, MTV predicted progression-free (HR = 4.23; p < 0.0001) and overall (HR = 3.21; p = 0.0029) survival in patients with p16{sup INK4a}-positive oropharyngeal cancer. Conclusions: This study validates our previous findings that MTV independently predicts outcomes in HNC. MTV should be considered as a potential risk-stratifying biomarker in future studies of HNC.

Specifically, we reviewed published instruments developed to assess psychological distress (depression, anxiety, stress, and fear of recurrence, psychological growth (resilience, posttraumatic growth, and benefit finding, unmet needs, coping, quality of life, identity, and mindfulness-based practices and skills in AYAs with cancer. Given the dearth of validated instruments targeting AYAs with cancer, this review also provides a summary of promising measures yet to be formally validated in this population.Methods: Five electronic databases were searched by a team of six researchers, and studies involving AYAs (who have or have had cancer aged 15–30 years, and published between 1982 and 2012 were reviewed. Of 410 abstracts, 7 instruments were identified as validated in this population, with a further 19 identified as promising.Results: While there are numerous scales to assess psychosocial outcomes in cancer, few have been specifically validated for AYAs affected by cancer, particularly in the domains of psychological distress, psychological growth, coping, unmet needs, and identity. There are relatively more instruments validated, or promising, for assessment of quality of life than scales for other domains.Conclusion: In the AYA context

    Full Text Available Background: Patients who undergo emergency colorectal cancer surgery has poor outcome compared to elective surgery, both in terms of morbidity and mortality. Approximately 15 to 30% of colorectal cancers present as an emergency, most often as obstruction or perforation. Objective: To compare surgical outcome and clinical profiles of emergency and elective cases for colorectal cancer. Methods: Retrospective analysis of 34 cases who underwent surgery for colorectal cancer between December 2011 to January 2013was carried out and their surgical outcomes, clinical presentation, demographic profile were analyzed. Results: The total numbers of patients included in this study were 34. Out of which 52.94 %( n=18 were emergency cases and 47.05 %( n=16 were elective. Male female ratio was 3:1 in emergency cases and 2.6:1 in elective cases. Per rectal bleeding (56% and altered bowel habit (31.25% was predominant clinical presentation in elective cases whereas intestinal obstruction (55.55% and peritonitis (22.22% were predominant clinical presentation in emergency cases. In emergency cases most of the tumors were located in left side (77.77% and in elective cases rectum was common site (37.5%. Left hemicolectomy was the commonest surgery performed (72.22% in emergency set up. In elective cases, right hemicolectomy, left hemicolectomy, APR and LAR was done in 31.25%, 31.25%, 25% and 25% cases respectively. In the emergency group 11.11% (n=2 developed enterocutaneous fistula and early mortality within 30 days was observed in 5% (n=1 of emergency cases only. Conclusion: In emergency conditions, colorectal cancer presented with intestinal obstruction where as elective cases presented with per rectal bleeding and altered bowel habits. Compared with the elective patients, the emergency patients had higher rate of morbidity and mortality. Because of higher incidence of colorectal cancer in our institution, in all emergency cases who presents with features of

  14. Expression of vascular endothelial growth factor (VEGF) in locally invasive prostate cancer is prognostic for radiotherapy outcome

    International Nuclear Information System (INIS)

    Purpose: Vascular endothelial growth factor (VEGF) is an important hypoxia-inducible pro-angiogenic protein that has been linked with an adverse survival outcome after radiotherapy in other cancer types: we hypothesized that this may also occur in prostate cancer. A retrospective study was, therefore, carried out to evaluate the potential of tumor VEGF expression to predict radiotherapy outcome in patients with high-risk prostate cancer. Methods and Materials: Fifty patients with locally advanced (T3 N0 M0) tumors of Gleason score ≥6, and who received radiotherapy alone as primary treatment for their disease, were studied. Vascular endothelial growth factor expression was assessed on pretreatment diagnostic tumor biopsies using a semiquantitative immunohistochemical scoring system. The results were analyzed in relation to clinicopathologic factors and patient outcome including biochemical failure and disease-specific mortality. Results: High VEGF expression was associated with a poor prognosis: in univariate log rank analysis, VEGF was the only significant prognostic factor for disease-specific survival (p = 0.035). High VEGF expression also associated with increased Gleason score (p = 0.02), but not posttreatment biochemical failure. Conclusion: High tumor expression of VEGF identified patients at high risk of failure of treatment with radiotherapy. These patients might benefit from additional treatment approaches incorporating anti-angiogenic or hypoxia-specific agents

    Full Text Available Suzanne S Dickerson, Laurie M Connors, Ameera Fayad, Grace E Dean School of Nursing, State University of New York, University at Buffalo, NY, USA Purpose: Evidence suggests a high prevalence of sleep–wake disturbances in patients with cancer, occurring at diagnosis, during treatment, and continuing to survivorship. Yet associations between sleep–wake disturbances and the impact on quality of life outcomes is less clear. The purpose of this narrative review of the literature is to evaluate sleep–wake disturbances in patients with cancer, to describe the influence of poor sleep on quality of life as an outcome, and to evaluate the evidence to recommend future interventions. Framework and methods: This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA approach. Four databases (CINAHL, MEDLINE, PsycINFO, and Embase were searched using terms "cancer OR neoplasm", "sleep, sleep disturbance, sleep disorders or insomnia", and "quality of life"; the search included all years, English language, and peer-reviewed articles on research studies. Studies included measurements of sleep and quality of life in cancer patients at a minimum of two time points and demonstrated relationships between sleep and quality of life. Data were collected on date, patient demographics, cancer type and treatment, timeframe, design, measurement, variables, and results. Results: This narrative review demonstrates that sleep–wake disturbance is a major problem/symptom in patients with cancer. Of the 18 studies included, measurement of sleep-related variables included objective and subjective measures; however, direct measurement of the associations between sleep and quality of life was not common. Cognitive behavioral therapy for insomnia and mind–body interventions demonstrated feasibility when implemented into cancer care settings. In addition, the majority of interventions exhibited moderate effectiveness in improving

    Full Text Available Multiple studies have investigated the effect of perioperative blood transfusion (PBT for patients with radical cystectomy (RC, but the results have been inconsistent. We conducted a systematic review and meta-analysis to investigate the relationship between PBT and the clinical outcomes of RC patients.We searched MEDLINE, EMBASE, the Cochrane library and BIOSIS previews to identify relevant literature for studies that focused on the relationship of PBT and outcomes of patients undergoing RC. A fixed or random effects model was used in this meta-analysis to calculate the pooled hazard ratio (HR with 95% confidence intervals (CIs.A total of 7080 patients in 6 studies matched the selection criteria. Aggregation of the data suggested that PBT in patients who underwent RC correlated with increased all-cause mortality, cancer-specific mortality and cancer recurrence. The combined HRs were 1.19 (n = 6 studies, 95% CI: 1.11-1.27, Z = 4.71, P<0.00001, 1.17 (n = 4 studies, 95% CI: 1.06-1.30, Z = 3.06, P = 0.002, 1.14 (n = 3 studies, 95% CI: 1.03-1.27, Z = 2.50, P = 0.01, respectively. The all-cause mortality associated with PBT did not vary by the characteristics of the study, including number of study participants, follow-up period and the median blood transfusion ratio of the study.Our data showed that PBT significantly increased the risks of all-cause mortality, cancer-specific mortality and cancer recurrence in patients undergoing RC for bladder cancer.

    Full Text Available Purpose : Although radical radiotherapy is known to be equally effective for early-stage oral tongue cancers (T1-2 N0 with the added advantage of organ and function preservation, surgery remains the preferred treatment. We present outcome of patients treated with brachytherapy (BT either radical or boost. Materials and Methods : Fifty-seven patients (T1/T2 31/26 were studied. Seventeen patients (30% were treated with radical BT (50-67 Gy while 40 (70% with external beam radiation therapy (EBRT + BT (36-56 Gy + 15-38 Gy]. Low-dose-rate (LDR BT was delivered with 192 Ir wires, using plastic bead technique with varied dose rates (< 60 cGy/h in 29 patients, 60-90 cGy/h in 17, and> 90 cGy/h in 11. Results : The overall local control (LCR was achieved in 59.7% (34/57 patients. LCR for T1 and T2 was 67.8% and 50%, respectively. A total of 23 patients had failures [local: 20 (T1: 8; T2: 12 patients, node: 5 (T1:2; T2: 3, and local + nodal: 3]. Overall 5-year disease-free survival and overall survival (OAS were 51% and 67%, respectively and those for T1 and T2 was 64.5/77.4% and 38.5/54% respectively (P = 0.002. All 16 patients were salvaged. Median survival after salvage treatment was 13.5 months (6-100 months. Soft tissue necrosis was observed in 12.3% (7/57 and osteoradionecrosis in two patients. Conclusion : BT, as an integral part of radical radiation therapy in early-stage tongue cancers, appears to be an effective alternative treatment modality with preservation of the organ and function without jeopardizing the outcome.

  19. Outcome of different oncoplastic surgical (OPs) techniques for centrally located breast cancer (CLBC)

    International Nuclear Information System (INIS)

    Background: Oncoplastic breast surgery is a standard treatment of early breast cancer, offering a balance between good cosmetic outcome and limited risk of locoregional recurrence, by enabling proper resection margins. Aim of study: To present multiple techniques of partial breast reconstruction following the resection of centrally located breast cancer (CLBC) resection. Patients and methods: From January 2011 to August 2014, 21 patients underwent central quadrantectomy for carcinoma of the central region of the breast. Excisions included the nipple/areola complex, in most of the cases, down to the pectoralis fascia with a wide safety margin, and proper axillary management. Oncoplastic approaches included latissimus dorsi flap, inferior pedicle flap, Melon slice, Grisotti and round block techniques. Results: Mean age of patients was 49.5 ± 10.61 years. Tumor size ranged from 1.5 to 4.5 cm. Postoperative pathology revealed a tumor mean safety margin of 2.5± 0.83 cm, with positive axillary lymph nodes in 15 (75.0%) patients. Nineteen (95.0%) patients received postoperative breast radiotherapy, while 9/20 (45.0%) and 3/20 (15.0%) received adjuvant chemotherapy or hormonal therapy, respectively, and only 8/20 (40.0%) patients received both therapies. During a median follow- up period of 14.89 months, neither local nor distant metastasis, were detected. The postoperative cosmetic result evaluated by the patients was excellent in 6/20 patients (30.0%), good in 11/20 patients (55.0%), fair in 3/20 (15.0%) with neither poor nor bad results, with an overall mean of 4.0 ± 0.5 equivalent to 80% satisfaction. Conclusion: Multiple oncoplastic breast surgery techniques can be used for the resection of CLBC with satisfying cosmetic outcomes.

    Mutations in the TP53 gene are very common in human cancers, and are associated with poor clinical outcome. Transgenic mouse models lacking the Trp53 gene or that express mutant Trp53 transgenes produce tumours with malignant features in many organs. We previously showed the transcriptome of a p53-deficient mouse skin carcinoma model to be similar to those of human cancers with TP53 mutations and associated with poor clinical outcomes. This report shows that much of the 682-gene signature of this murine skin carcinoma transcriptome is also present in breast and lung cancer mouse models in which p53 is inhibited. Further, we report validated gene-expression-based tests for predicting the clinical outcome of human breast and lung adenocarcinoma. It was found that human patients with cancer could be stratified based on the similarity of their transcriptome with the mouse skin carcinoma 682-gene signature. The results also provide new targets for the treatment of p53-defective tumours. PMID:22880004

    Background Mesothelin, previously shown to be expressed in triple negative breast cancer (TNBC), is a potential therapeutic target and prognostic marker in breast cancer. Methods We analyzed clinical data from two cohorts comprising of 141 patients treated between 2009 and 2011 at our institution (discovery cohort) and 844 patients from The Cancer Genome Atlas (TCGA) (validation cohort). Mesothelin expression was quantified by immunohistochemistry (IHC) or by RNA transcript levels as measured by whole-transcriptome sequencing in the discovery and validation cohorts respectively. Results In the discovery cohort, the median follow up was 3.55 years. Univariate analyses demonstrated that tumor size (hazard ratio (HR) =1.30, 95% confidence interval (CI) 1.11–1.51), positive (+) axillary lymph nodes (HR=3.34; 95% CI 1.51–7.39), and mesothelin expression (HR = 2.03; 95% CI 1.10–3.74) were associated with overall and disease-specific survival. We used a Cox-proportional hazard (Cox-PH) model to adjust for the two independent predictors of survival, namely (+) axilla lymph nodes and tumor size, and we found a significant association between mesothelin expression and overall and disease-specific survival in the discovery cohort (HR = 3.06, 95% CI 1.40–6.68). Using the TCGA dataset, we confirmed that, over a median follow-up of 16.0 months, patients with mesothelin-expressing tumors had poorer overall survival (HR=1.46; 95% CI 1.05–2.03). On Cox-PH multivariate analysis, mesothelin-positivity was an independent predictor of worse survival, after adjusting for (+) axillary lymph nodes and tumor size (HR = 1.69; 95%CI 1.17–2.42). Conclusions Our results suggest that mesothelin is a prognostic breast tumor marker whose expression is highly enriched in TNBC tumors, especially in African American women. As there is no existing targeted therapy for TNBC, mesothelin may be a promising drug target for TNBC. Future work is needed to evaluate the efficacy of mesothelin

    Full Text Available Cisplatin based concomitant chemoradiation (CRT is the standard treatment for locally advanced cervical cancer (CC. Glutathione S-transferase (GST, a phase II antioxidant enzyme is induced by oxidative stress generated by drugs and reactive oxidants. The present study was undertaken to evaluate the association of GSTM1, T1 and P1 polymorphisms with the outcome of CRT treatment in CC patients.A total of 227 cervical cancer patients with stages IIB-IIIB treated with the same chemoradiotherapy regimen were enrolled and genotyped for GSTM1, T1 and P1 gene polymorphisms by multiplex polymerase chain reaction (mPCR and PCR-restriction fragment length polymorphism (PCR-RFLP. Overall survival was evaluated using Kaplan-Meier survival function and Cox proportional hazards model. All data were analyzed using SPSS (version 21.0.Stratified analysis showed that GSTM1 null (M1- genotype was associated with a significantly better survival among patients with stage IIB cervical cancer (log-rank P = 0.004 than cases with stage IIIA/IIIB. Death and recurrence were significantly higher in patients with GSTM1 present genotype (M1+ (P = 0.037 and P = 0.003 respectively and those with M1- showed reduced hazard of death with an adjusted hazard ratio 'HR' of 0.47 (95% CI, 0.269-0.802, P = 0.006. Women with M1- genotype as well as in combination with GSTT1 null (T1-, GSTP1 (AG+GG and GSTT1 null/GSTP1 (AG+GG showed better survival and also reduced risk of death (HR = 0.31, P = 0.016; HR = 0.45, P = 0.013; HR = 0.31, P = 0.02 respectively.To the best of our knowledge, this is the first study to correlate the association of GSTM1, T1 and P1 gene polymorphisms with treatment outcome of CRT treated CC patients. Our results suggested that individuals with GSTM1 null genotype and in combination with GSTT1 null and GSTP1 (AG+GG had a survival advantage. Such genetic studies may provide prognostic information in CRT treated CC patients.

    Xeroderma pigmentosum group G (XPG), one of key components of nucleotide excision repair pathway (NER), is involved in excision repair of UV-induced DNA damage. Single nucleotide polymorphisms (SNPs) in the XPG gene have been reported to associate with the clinical outcome of various cancer patients. We aimed to assess the impact of four potentially functional SNPs (rs2094258 C>T, rs2296147 T>C, rs751402 G>A, and rs873601 G>A) in the XPG gene on prognosis in colorectal cancer (CRC) patients. A total of 1901 patients diagnosed with pathologically confirmed CRC were genotyped for four XPG polymorphisms. Cox proportional hazards model analysis controlled for several confounding factors was conducted to compute hazard ratios (HRs) and 95% confidence intervals (CIs). Of the four included SNPs, only rs2296147 was shown to significantly affect progression-free survival (PFS) in CRC. Patients carrying rs2296147 CT/TT genotype had a significantly shorter median 10 years PFS than those carrying CC genotype (88.5 months vs. 118.1 months), and an increased progression risk were observed with rs2296147 (HR = 1.324, 95% CI = 1.046-1.667). Moreover, none of the four SNPs were associated with overall survival. In conclusion, our study showed that XPG rs2296147 CT/TT variants conferred significant survival disadvantage in CRC patients in term of PFS. XPG rs2296147 polymorphism could be predictive of unfavorable prognosis of CRC patients. PMID:26887052

    Full Text Available Metastatic breast cancer (MBC remains a devastating and incurable disease. Over the past decade, the implementation of clinical trials both with and without molecular targeted therapeutics has impacted the daily clinical treatment of patients with MBC. In this study, we determine whether including MBC patients in clinical trials affects clinical outcomes.We retrospectively reviewed data for a total of 863 patients diagnosed with initial or recurrent (after receiving adjuvant systemic treatments following surgery metastatic disease between January 2000 and December 2013. Data were obtained from the breast cancer database of Samsung Medical Center.Among the 806 patients selected for inclusion, 188 (23% had participated in clinical trials. A total of 185 clinical trials were conducted from 2000 to 2014. When compared with earlier periods (n = 10 for 2000-2004, clinical trial enrollment significantly increased over time (n = 103 for 2005-2009, P = 0.024; n = 110 for 2010-2014, P = 0.046. Multivariate analyses revealed that biologic subtype, distant recurrence free interval (DRFI, and clinical trial enrollment were independent predictors of overall survival. Patients who participated in clinical trials showed improved survival, with a hazard ratio of 0.75 (95% CI, 0.59-0.95, which was associated with a 25% reduction in the risk of death. However, subgroup analysis showed that this improved survival benefit was not maintained in patients with triple negative breast cancer (TNBC.Although not conclusive, we could speculate that there were differences in the use of newer agents or regimens over time, and these differences appear to be associated with improved survival.

    Background and purpose: Tumor volume (TV) is recognized as a prognostic factor of treatment outcome for head and neck tumors but is not routinely included in the treatment decision-making process. The purpose of the study was to define its prognostic role for patients with T2 laryngeal cancer. Material and methods: TV of 160 patients who underwent RT between 2002 and 2006 for T2 laryngeal squamous cell carcinoma were reviewed. The tumor was located in the glottis and epiglottis in 82 (51 %) and 78 (49 %) patients, respectively. TV was manually contoured on pretreatment, planning, contrast-enhanced CT scans and the volumetric measurement (cm{sup 3}) was calculated by the volume algorithm. Results: The median TV value was 2.01 cm{sup 3} (range 0.15-21.68 cm{sup 3}). The median TV was significantly lower in patients with glottic tumors (p < 0.0001), N0 (p < 0.001), or well histopatologically differentiated tumors (p = 0.01). A significant correlation between TV, hemoglobin concentration (p < 0.01), and total dose (TD; p < 0.001) was observed. On univariate analyses, TV influenced local control (LC; p = 0.02) and overall survival (OS, p < 0.001). On multivariate analysis, both age (HR 1.038, p = 0.03) and TV (HR = 1.075, p = 0.01) remained significantly related to LC and OS (age: HR 1.038, p = 0.005; TV: HR 1.097, p = 0.0001). Conclusion: Large TV worsen prognosis of patients with T2 laryngeal cancer. A large TV is more common for supraglottic, poorly differentiated tumors and may suggest higher risk of nodal spread. The routine estimation of TV prior to therapy may be essential in order to select the best treatment option for patients with T2 laryngeal cancer. (orig.)

    Full Text Available Background: The beginning of metastasis poorly affects the prognosis of breast cancer patients. Lung is the most frequent site of visceral metastasis, and the rate of recurrence is 10-30%. We have tried to find out if the routine Chest X Ray (CXR could play a role for early detection of lung metastasis, during the prognosis of these patients.Methods: The files of the breast cancer patients between 1996 to 2006 (1739 patients have reviewed. Clinical characteristics of patients with pulmonary metastasis have recorded. Patients, who lacked imaging files or lacked an appropriate follow-up, have excluded. Data have analyzed by SPSS 11.5. The survival analyses have performed by using the Kaplan-Meier method.Results: Fifty-six patients, median age 46, have entered into this retrospective study. Median tumor size was 4cm; median number of Lymphadenopathy (LAP was 4. The intermediate grade has detected in 74% of patients. All patients have received adjuvant treatment. Median time from cancer diagnosis to pulmonary metastasis was 22 months. Pulmonary metastasis has detected by control CXR in 77.4% and patients' symptoms in 22.6%. Forty eight patients have received chemotherapy in metastatic phase. In 28 patients (50%, other sites of metastasis (bone, liver, and brain have discovered.The most frequent pattern of lung recurrence was pulmonary nodule (44.6%, followed by pleural effusion (28.6%. Median survival was 27.5; median survival from pulmonary metastasis was 8 m.Conclusion: Early detection of pulmonary metastasis by CXR did not affect patients' endpoints. None of the probable prognostic factors have shown a significant effect on patients' outcome. Despite systemic treatment, survival after metastasis is low.

    Cervical cancer (CC) is the third most diagnosed cancer among females worldwide and the fourth cause of cancer-related mortality. Prophylactic HPV vaccines and traditional pap-smear screening are undoubtedly capable of decreasing the incidence and mortality of CC. However, a large number of females succumb to the disease each year due to late diagnosis and resistance to conventional treatments. Thus, it is necessary to identify new molecular markers to predict the clinical outcome and to design powerful treatments. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression and are involved in the modulation of several cell pathways associated with progression from pre-malignant to invasive and metastatic disease, increasing tumor malignancy. The aim of this review was to summarize the recent data that describe the important role of miRNAS involved in CC in order to determine their potential as prognostic biomarkers and as therapy targets. Studies of >40 miRNAs with roles in cancer regulation were identified. We also identified 17 miRNAs associated with progression, 12 involved with clinical outcome and 7 that improved CC treatment response. The present review is expected to broaden understanding of the functional role and potential clinical uses of miRNAs in CC. PMID:26530778

  14. Tolerability and outcomes of radiotherapy or chemoradiotherapy for rectal cancer in elderly patients aged 70 years and older

    International Nuclear Information System (INIS)

    To assess the safety and outcomes of radiotherapy (RT) or chemoradiotherapy (CRT) in elderly patients (≥70) with rectal cancer. Elderly patients aged 70 and older with rectal cancer, who were treated with RT or CRT at a single institution, were retrospectively analyzed. Performance status (KPS and ECOG score) and comorbidity (Charlson comorbidity index) were calculated, and their correlation with treatment toxicity and overall survival were studied. Risk factors for overall survival were investigated using univariate and multivariate survival analysis. A total of 126 patients with locally advanced disease, local recurrence or synchronous metastasis were included, with a 3-year OS rate of 48.1%. Scheduled dosage of radiation was delivered to 69% of patients. Grade 3 toxicities occurred more often in patients treated with CRT versus RT. The occurrence of grade 3 toxicities was not related to KPS score, ECOG score, number of comorbidities, and Charlson score. Multivariate analysis found that only age and Charlson score were independent prognostic factors for predicting patients’ 3-year OS. The 3-year OS rate was significantly higher in patients with Charlson score <4 vs Charlson score ≥4 (71.1% vs. 26.4%, P=0.0003). Although toxicities may be significant, elderly patients with rectal cancer of varied stages can be safely treated with RT or CRT with careful monitoring and frequent modification of treatment. Except for patients’ age, Charlson comorbidity index may be helpful in assessing patients’ outcomes in elderly patients with rectal cancer

    Full Text Available Cancer in adolescents and young adults (AYAs (15-39 years is increasingly recognized as a distinct clinical and biological entity. Cancer of unknown primary (CUP, a disease traditionally presenting in older adults with a median age of 65 years, poses several challenges when diagnosed in AYA patients. This study describes clinicopathological features, outcomes and challenges in caring for AYA-CUP patients.A retrospective review of 47 AYAs diagnosed with CUP at MD Anderson Cancer Center (6/2006-6/2013 was performed. Patients with favorable CUP subsets treated as per site-specific recommendations were excluded. Demographics, imaging, pathology and treatment data was collected using a prospectively maintained CUP database. Kaplan-Meier product limit method and log-rank test were used to estimate and compare overall survival. The cox-proportional model was used for multivariate analyses.Median age was 35 years (range 19-39. All patients underwent comprehensive workup. Adenocarcinoma was the predominant histology (70%. A median of 9 immunostains (range 2-29 were performed. The most common putative primary was biliary tract based on clinicopathological parameters as well as gene profiling. Patients presented with a median of 2 metastatic sites [lymph node (60%, lung (47%, liver (38% and bone (34%]. Most commonly used systemic chemotherapies included gemcitabine, fluorouracil, taxanes and platinum agents. Median overall survival for the entire cohort was 10.0 (95% confidence interval (CI: 6.7-15.4 months.

    AIM: To investigate prognostic factors of survival following curative, non-palliative surgical removal of lung metastases secondary to colorectal cancer (CRC). METHODS: Between 1999 and 2009, a radical metastasectomy with curative intent was performed on lung metastases in 21 patients with CRC (15 male and 6 female; mean age: 57.4 ± 11.8 years; age range: 29-74 years) who had already undergone primary tumour resection. RESULTS: The mean number of lung metastases ranged from one to five. The mean overall survival was 71 ± 35 mo (median: 25 mo). After adjusting for potential confounders, multivariable Cox regression analyses predicted only the number of lung metastases (1 vs ≥ 2; hazard ratio: 7.60, 95% confidence interval: 1.18-17.2, P = 0.03) as an independent predictor of poor survival following lung resection for metastatic CRC. CONCLUSION: Resection of lung metastases is a safe and effective treatment in selected CRC patients with single lung metastases. PMID:22363137

    Background Mitosis is a highly regulated process that serves to ensure the fidelity of cell division. Disruption of mitotic regulators leading to aneuploidy and polyploidy is commonly observed in cancer cells. Single nucleotide polymorphisms (SNPs) in regulators of mitosis may promote chromosome mis-segregation and influence pancreatic cancer and/or survival. Methods Thirty four SNPs, previously associated with breast cancer risk, from 33 genes involved in regulation of mitosis, were investigated for associations with pancreatic cancer risk in 1,143 Caucasian patients with pancreatic adenocarcinoma and 1,097 unaffected controls from the Mayo Clinic. Associations with survival from pancreatic cancer were also assessed using 1,030 pancreatic cancer cases with known outcome. Results Two SNPs in the APC (rs2431238) and NIN (rs10145182) loci, out of 34 examined, were significantly associated with pancreatic cancer risk (p=0.035 and p=0.038, respectively). Further analyses of individuals categorized by smoking and BMI identified several SNPs displaying significant associations (p<0.05) with pancreatic cancer risk, including APC rs2431238 in individuals with high body mass index (BMI≥30) (p=0.031) and NIN rs10145182 in ever smokers (p=0.01). In addition, survival analyses detected significant associations between SNPs in EIF3S10 and overall survival (p=0.009), SNPs from five genes and survival in resected cancer cases (p<0.05), and SNPs from two other genes (p<0.05) and survival of locally advanced cancer cases. Conclusion Common variation in genes encoding regulators of mitosis may independently influence pancreatic cancer susceptibility and survival. PMID:20056645

    Background: A genome-wide association study (GWAS) suggested inherited genetic single-nucleotide polymorphisms (SNPs) affecting overall survival (OS) in advanced pancreatic cancer. To identify robust clinical biomarkers, we tested the strongest reported candidate loci in an independent patient cohort, assessed cellular drug sensitivity, and evaluated molecular effects. Methods: This study comprised 381 patients with histologically verified pancreatic ductal adenocarcinoma treated with gemcitabine-based chemotherapy. The primary outcome was the relationship between germline polymorphisms and OS. Functional assays addressed pharmacological dose-response effects in lymphoblastoid cell lines (LCLs) and pancreatic cancer cell lines (including upon RNAi), gene expression analyses, and allele-specific transcription factor binding. All statistical tests were two-sided. Results: The A allele (26% in Caucasians) at SNP rs11644322 in the putative tumor suppressor gene WWOX conferred worse prognosis. Median OS was 14 months (95% confidence interval [CI] = 12 to 15 months), 13 months (95% CI = 11 to 15 months), and nine months (95% CI = 7 to 12 months) for the GG, GA, and AA genotypes, respectively (P trend < .001 for trend in univariate log-rank assuming a codominant mode of inheritance; advanced disease subgroup P trend < .001). Mean OS was 25 months (95% CI = 21 to 29 months), 19 months (95% CI = 15 to 22 months), and 13 months (95% CI = 10 to 16 months), respectively. This effect held true after adjustment for age, performance status according to Eastern Cooperative Oncology Group classification, TNM, grading, and resection status and was comparable with the strongest established prognostic factors in multivariable analysis. Consistently, reduced responsiveness to gemcitabine, but not 5-fluorouracil, along with lower WWOX expression was demonstrated in LCLs harboring the AA genotype. Likewise, RNAi-mediated WWOX knockdown in pancreatic cancer cells confirmed differential

    Purpose Addition of bevacizumab to trastuzumab-based neoadjuvant chemotherapy in HER2-positive inflammatory breast cancer (IBC) was associated with favorable outcome in the BEVERLY-2 phase II trial. Circulating levels of matrix metalloproteinases (MMP) 2 and 9 were correlated to high response rate and prolonged survival in high-grade glioma treated with bevacizumab. We examined the prognostic impact of MMP2 and MMP9 serum levels in BEVERLY-2 patients. Experimental design MMP2 and MMP9 serum levels were assessed using ELISA at baseline and before surgery in 45/52 available samples. Correlations were tested with pathological complete response (pCR), disease-free survival (DFS) and overall survival (OS). Results Baseline (b) MMP2 and MMP9 serum levels were independent from patient characteristics and circulating tumor or endothelial cells, and were not correlated to pCR. High bMMP2 was correlated to better DFS (p=0.001) and OS (p=0.032), while low bMMP9 was correlated to better OS (p=0.022) and tended to be associated with longer DFS (p=0.071). In multivariate analyses, bMMP2 (p=0.003, Hazard Ratio [HR]: 0.115) and bMMP9 (p=0.041, HR: 3.511) remained correlated to DFS. As continuous variables, bMMP2 was associated with relapse (p=0.002) and death (p=0.049), while bMMP9 was associated with death (p=0.035). During treatment, significant increase in MMP2 and decrease in MMP9 levels (pchemotherapy. Their predictive value of bevacizumab benefit should be evaluated in a randomized trial. PMID:26921265

    AIM: To investigate if contrast-enhanced ultrasono-graphy (CE-US) is useful for determining treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy by assessing changes in intratumor hemodynamics using CE-US with a contrast agent.METHODS: The subjects were 34 patients with unresectable advanced pancreatic cancer treated by chemotherapy. CE-US was assessed after every treatment (course) completion under the same conditions, and patients were divided into two groups according to the intratumor enhancement pattern: Vascular rich (R) group and vascular poor (P) group. RESULTS: After the second course of treatment, R group in intratumor hemodynamics had 18 patients, and P group had 16 patients. The reduction rates of serum CA19-9 level after chemotherapy which decreased to half or less of the baseline level were 2/15 (0.1%) in P group, but 11/16 (69%) in R group (P = 0.006). When the mean number of courses of chemotherapy and outcome were compared, P group had a mean number of courses of 4.9 (R group, 10.2) and mean survival time (MST) of 246 d (R group, 402 d), showing that outcome was significantly better in R group (P = 0.006).CONCLUSION: CE-US revealed that the change in intratumor blood flow correlated with both serum CA19-9 level and outcome. Patients with serum CA19-9 that decreased to less than half the baseline level, and patients with an abundant intratumor blood flow, had a significantly better outcome. Thus, CE-US is tentially useful for evaluating treatment efficacy and outcome in the early stages of pancreatic cancer chemotherapy.

  11. Expression profiling to predict outcome in breast cancer: the influence of sample selection

    International Nuclear Information System (INIS)

    Gene expression profiling of tumors using DNA microarrays is a promising method for predicting prognosis and treatment response in cancer patients. It was recently reported that expression profiles of sporadic breast cancers could be used to predict disease recurrence better than currently available clinical and histopathological prognostic factors. Having observed an overlap in those data between the genes that predict outcome and those that predict estrogen receptor-α status, we examined their predictive power in an independent data set. We conclude that it may be important to define prognostic expression profiles separately for estrogen receptor-α-positive and estrogen receptor-α-negative tumors

  12. Patient-reported outcomes following stereotactic body radiation therapy for clinically localized prostate cancer

    International Nuclear Information System (INIS)

    Stereotactic body radiation therapy (SBRT) delivers high doses of radiation to the prostate while minimizing radiation to adjacent normal tissues. Large fraction sizes may increase the risk of functional decrements. Treatment-related bother may be more important to a patient than treatment-related dysfunction. This study reports on patient-reported outcomes following SBRT for clinically localized prostate cancer. Between August 2007 and July 2011, 228 consecutive hormone-naïve patients with clinically localized prostate cancer were treated with 35–36.25 Gy SBRT delivered using the CyberKnife Radiosurgical System (Accuray) in 5 fractions. Quality of life was assessed using the American Urological Association Symptom Score (AUA) and the Expanded Prostate Cancer Index Composite (EPIC)-26. Urinary symptom flare was defined as an AUA score 15 or more with an increase of 5 or more points above baseline 6 months after treatment. 228 patients (88 low-, 126 intermediate- and 14 high-risk) at a median age of 69 (44–90) years received SBRT with a minimum follow-up of 24 months. EPIC urinary and bowel summary scores declined transiently at 1 month and experienced a second, more protracted decline between 9 months and 18 months before returning to near baseline 2 years post-SBRT. 14.5% of patients experienced late urinary symptom flare following treatment. Patients who experienced urinary symptom flare had poorer bowel quality of life following SBRT. EPIC scores for urinary bother declined transiently, first at 1 month and again at 12 months, before approaching pre-treatment scores by 2 years. Bowel bother showed a similar pattern, but the second decline was smaller and lasted 9 months to 18 months. EPIC sexual summary and bother scores progressively declined over the 2 years following SBRT without recovery. In the first 2 years, the impact of SBRT on urination and defecation was minimal. Transient late increases in urinary and bowel dysfunction and bother were observed

    Full Text Available Purpose: Obesity has been generally associated with increased surgical risk. However, data on the outcome of laparoscopic colectomy in obese and non-obese patients are controversial. The aim of this study is to assess the short-term outcome of laparoscopic colectomy for colorectal cancer (CRC in obese patients as compared with non-obese patients. Materials and Methods: Sixty-nine patients who underwent laparoscopic anterior resection for CRC during the past six years were retrospectively evaluated. The patients with CRC involving the sigmoid or rectosigmoid colon and subjected to intracorporeal anastomosis were included in this study. They were divided into three groups according to body mass index (BMI: obese (BMI ≥ 28.0 kg/m 2 , pre-obese (BMI: 25.0-27.9 kg/m 2 and non-obese (BMI < 25.0 kg/m 2 . Results: Nine patients (13.0 % were obese, 11 patients (15.9% were pre-obese and 49 patients (71.1% were non-obese. Patient characteristics, such as age, gender, tumor location, previous laparotomy, were similar among the three groups. There were no significant differences in operative time, blood loss, intraoperative complications and conversion rates. Postoperative complications and duration of postoperative hospital stay were also similar among the three groups. However, two of the three patients in the pre-obese group had to be operated on again due to incarceration of the small bowel into a port site. Conclusions: Laparoscopic colectomy can be safely performed in obese patients with short-term results similar to those obtained in non-obese and pre-obese patients.

  14. Long-Term Quality of Life Outcome After Proton Beam Monotherapy for Localized Prostate Cancer

    International Nuclear Information System (INIS)

    Objectives: High-dose external radiation for localized prostate cancer results in favorable clinical outcomes and low toxicity rates. Here, we report long-term quality of life (QOL) outcome for men treated with conformal protons. Methods: QOL questionnaires were sent at specified intervals to 95 men who received proton radiation. Of these, 87 men reported 3- and/or 12-month outcomes, whereas 73 also reported long-term outcomes (minimum 2 years). Symptom scores were calculated at baseline, 3 months, 12 months, and long-term follow-up. Generalized estimating equation models were constructed to assess longitudinal outcomes while accounting for correlation among repeated measures in an individual patient. Men were stratified into functional groups from their baseline questionnaires (normal, intermediate, or poor function) for each symptom domain. Long-term QOL changes were assessed overall and within functional groups using the Wilcoxon signed-rank test. Results: Statistically significant changes in all four symptom scores were observed in the longitudinal analysis. For the 73 men reporting long-term outcomes, there were significant change scores for incontinence (ID), bowel (BD) and sexual dysfunction (SD), but not obstructive/irritative voiding dysfunction (OID). When stratified by baseline functional category, only men with normal function had increased scores for ID and BD. For SD, there were significant changes in men with both normal and intermediate function, but not poor function. Conclusions: Patient reported outcomes are sensitive indicators of treatment-related morbidity. These results quantitate the long-term consequences of proton monotherapy for prostate cancer. Analysis by baseline functional category provides an individualized prediction of long-term QOL scores. High dose proton radiation was associated with small increases in bowel dysfunction and incontinence, with more pronounced changes in sexual dysfunction.

  15. HIV infection and invasive cervical cancers, treatment with radiation therapy: toxicity and outcome

    International Nuclear Information System (INIS)

    Background and purpose: To determine the effect of radiotherapy in HIV seropositive cervical cancer patients, tumour response and toxicity and compliance of patients to the treatment. Patients and methods: This study is a retrospective review of 42 HIV seropositive patients diagnosed with carcinoma cervix, between 1997 and 2003 at the Tata Memorial Hospital. The age and symptoms of presentation, clinical stage, response, compliance and tolerance to radiotherapy were studied. Results: Mean age at presentation was 41 years. All patients presented with the symptoms of cervical disease. Of these patients 31(74%) patients had 'Karnofsky Performance Scale' (KPS) more than 80%. Twenty-one (50%) of the patients were of Stage IIIb-IVa. Thirty-two (76%) were started on radiotherapy with radical intent. Compliance to radiotherapy was poor with 24% patients discontinuing after few fractions of radiotherapy. Seven (17%) patients were given palliative radiotherapy. Twenty-two patients completed prescribed radical radiotherapy and 50% of these achieved complete response. Grade III-IV acute gastrointestinal toxicity was seen in 14% of the patients, and grade III acute skin toxicity was seen in 27% of patients, leading to treatment delays. There was good relief of symptoms in patients treated with palliative intent. Conclusions: Radiotherapy is effective in this set of patients. Palliative fractionation schedules are effective for patients with poor performance status and locally advanced cancers in relieving the symptoms related to carcinoma cervix. An emphasis should be given to the increased acute mucosal and skin toxicity and to improving compliance and clinical outcome of these patients

    2012-12-01

    Full Text Available Background: The high number of breast cancer patients who receive radiation therapy after surgery has caused many to think about a shorter period of radiotherapy, which can significantly reduce the radiotherapy machine time, labor hours, and fewer patient visits. This study was designed to evaluate the acute skin effects and cosmetic outcomes of short course radiotherapy in early-stage breast cancer in comparison with the conventional treatment method.Methods: Fifty-two patients with operable breast cancer (pT1-3pN0M0 who underwent breast conservation surgery in Tehran Cancer Institute during January 2011 to January 2012, were randomly assigned to undergo radiotherapy by either receiving conventional treatment (dose: 50 Gy in 25 fractions with subsequent electron boost or a short-course hypofractionated radiotherapy (dose: 42.5 Gy in 16 fractions and a subsequent electron boost.Results: There were no skin changes during the first or the second week of treatment in the two groups. Cutaneous complications began after the third week as grade 1 skin toxicity after termination of the short-course radiotherapy but there were no difference in complication rate after four weeks of treatment. Six months and one year after treatment, there were no differences in terms of skin complications or cosmetic outcomes between the two groups.Conclusion: Although the use of a whole-breast irradiation with a hypofractionated schedule was associated with desirable outcomes, in term of skin toxicity and cosmetics, but longer follow-up periods with larger sample sizes are needed to confirm these results.

    Transthoracic esophagectomy (TTE) is believed to have advantages for mediastinal lymphadenectomy in the treatment of resectable esophageal cancer despite its association with a greater incidence of pulmonary complications and postoperative mortality. Transhiatal esophagectomy is regarded as less invasive, though insufficient in terms of lymph node dissection. With the aim of achieving lymph dissection equivalent to that of TTE, we have developed a nontransthoracic esophagectomy (NTTE) procedure combining a video-assisted cervical approach for the upper mediastinum and a robot-assisted transhiatal approach for the middle and lower mediastinum. We prospectively studied 22 accumulated cases of NTTE and verified feasibility by analyzing perioperative and histopathological outcomes. We compared this group's short-term outcomes with outcomes of 139 equivalent esophageal cancer cases operated on at our institution by conventional TTE (TTE group). In the NTTE group, there were no procedure-related events and no midway conversions to the conventional surgery; the mean operation time was longer (median, 524 vs. 428 minutes); estimated blood loss did not differ significantly between the two groups (median, 385 mL vs. 490 mL); in the NTTE group, the postoperative hospital stay was shorter (median, 18 days vs. 24 days). No postoperative pneumonia occurred in the NTTE group. The frequencies of other major postoperative complications did not differ significantly, nor were there differences in the numbers of harvested mediastinal lymph nodes (median, 30 vs. 29) or in other histopathology findings. NTTE offers a new radical procedure for resection of esophageal cancer combining a cervical video-assisted approach and a transhiatal robotic approach. Although further accumulation of surgical cases is needed to corroborate these results, NTTE promises better prevention of pulmonary complications in the management of esophageal cancer.

    The effectiveness of splanchnic nerve neurolysis (SNN) for cancer-related abdominal pain has been investigated using numeric pain intensity rating as an outcome variable. The outcome variable in this study used the grid method for obtaining a targeted pain drawing score on 60 patients with pain from pancreatic or gastro-intestinal primary cancers or metastatic disease to the abdominal region. Results demonstrate excellent inter-rater agreement (intra-class correlation [ICC] coefficient at pre-SNN = 0.97 and ICC at within one month post-SNN = 0.98) for the grid method of scoring the pain drawing and demonstrate psychometric generalizability among patients with cancer-related pain. Using the Wilcoxon signed rank test and associated effect sizes, results show significant improvement in dispersion of pain following SNN. Effect sizes for the difference in pre-SNN to 2 post-SNN time points were higher for the pain drawing than for pain intensity rating. Specifically, the effect size difference from pre- to within one month post-SNN was r = 0.42 for pain drawing versus r = 0.23 for pain intensity rating. Based on a smaller subset of patients who were seen within 1 - 6 months following SNN, the effect size difference from pre-SNN was r = 0.46 for pain drawing versus r = 0.00 for pain intensity rating. Collectively, these data support the use of the pain drawing as a reliable outcome measure among patients with cancer pain for procedures such as SNN that target specific location and dispersion of pain.

    Obesity is associated with a range of health outcomes that are of clinical and public health significance, including cancer. Herein, we summarize epidemiologic and preclinical evidence for an association between obesity and increased risk of breast and prostate cancer incidence and mortality. Moreover, we describe data from observational studies of weight change in humans and from calorie-restriction studies in mouse models that support a potential role for weight loss in counteracting tumor-promoting properties of obesity in breast and prostate cancers. Given that weight loss is challenging to achieve and maintain, we also consider evidence linking treatments for obesity-associated co-morbidities, including metformin, statins and non-steroidal anti-inflammatory drugs, with reduced breast and prostate cancer incidence and mortality. Finally, we highlight several challenges that should be considered when conducting epidemiologic and preclinical research in the area of obesity and cancer, including the measurement of obesity in population-based studies, the timing of obesity and weight change in relation to tumor latency and cancer diagnosis, and the heterogeneous nature of obesity and its associated co-morbidities. Given that obesity is a complex trait, comprised of behavioral, epidemiologic and molecular/metabolic factors, we argue that a transdisciplinary approach is the key to understanding the mechanisms linking obesity and cancer. As such, this review highlights the critical need to integrate evidence from both epidemiologic and preclinical studies to gain insight into both biologic and non-biologic mechanisms contributing to the obesity-cancer link.

  4. Functional outcome of gastrointestinal tract and quality of life after esophageal reconstruction of esophagus cancer

    International Nuclear Information System (INIS)

    Information about functional outcome and quality of life after esophagectomy and esophageal reconstruction (ER) for the treatment of esophageal cancer, as evaluated by the patients themselves is limited. We aimed to study the post-surgical outcome of such patients to detect for the development of any complications that may arise from the surgery as well as to evaluate their quality of life following the surgery. From 1993 to 2003, 240 patients with stage 1, 2, or 3 esophageal carcinoma underwent esophagectomy at Razi Teaching Hospital located in the north of Iran. Of these, 192 patients filled out a questionnaire during a 2-year period (ranging from 12 to 48 months after surgical reconstruction). Among them, there were 134 men (69%) and 58 women (31%), and the mean age at the time of ER was 48 years (ranging from 22 to 75 years). Transhiatal esophagectomy, extended esophagectomy (three field operation), and Ivor-Lewis resection were done in 142 (73.95%), 30 (15.62%), and 20 patients (10.42%), respectively. Intestinal continuity after esophageal resection was established with stomach in 154 patients (80%), colon in 28 patients (14%), and small bowel in 10 patients (5.2%). Cervical anastomosis was established in 172 patients (89.6%), while intrathoracic anastomosis was performed in 20 patients (10.4%). After ER, 66 patients (34.4%) suffered from dysphagia to solids and 50 patients (26%) required at least one or three postoperative dilatations for alleviation of symptoms. Gastroesophageal reflux was seen in 32 patients (16.66%) and was more common in thoracic anastomosis patients than in cervical anastomosis patients. Heartburn was present in 33 cases (17%), 30 of whom required medication (37%). The number of meals per day was three to four in 116 patients (60%), more than four in 51 patients (29%), and less than three in 19 patients (9.82%). The number of bowel movement per day increased in 52 patients (27%), decreased in 60 cases (31%), and unchanged in 80 patients

    Evaluation of intervention effects on multiple outcomes is a common scenario in clinical studies. In longitudinal studies, such evaluation is a challenge if one wishes to adequately capture simultaneous data behavior. In this situation, a common approach is to analyze each outcome separately. As a...... result, multiple statistical statements describing the intervention effect need to be reported and an adjustment for multiple testing is necessary. This is typically done by means of the Bonferroni procedure, which does not take into account the correlation between outcomes, thus resulting in overly...

    AIM: To evaluate the oncologic outcomes of primary and post-irradiated early stage rectal cancer and the effectiveness of adjuvant chemotherapy for rectal cancer patients. METHODS: Eighty-four patients with stage Ⅰ rectal cancer after radical surgery were studied retrospectively and divided into ypstage Ⅰ group (n = 45) and pstage Ⅰ group (n = 39), according to their preoperative radiation, and compared by univariate and multivariate analysis. RESULTS: The median follow-up time of patients was 70 mo. No significant difference was observed in diseaseprogression between the two groups. The 5-year disease-free survival rate was 84.4% and 92.3%, respectively (P = 0.327) and the 5-year overall survival rate was 88.9% and 92.3%, respectively, for the two groups (P = 0.692). The disease progression was not significantly associated with the pretreatment clinical stage in ypstage Ⅰ group. The 5-year disease progression rate was 10.5% and 19.2%, respectively, for the patients who received adjuvant chemotherapy and for those who rejected chemotherapy in the ypstage Ⅰ group (P = 0.681). CONCLUSION: The oncologic outcomes of primary and post-irradiated early stage rectal cancer are similar. Patients with ypstage Ⅰ rectal cancer may slightly benefit from adjuvant chemotherapy.

    Full Text Available Preexisting comorbidity adversely impacts breast cancer treatment and outcomes. We examined the incremental impact of comorbidity undetected until cancer. We followed breast cancer patients in SEER-Medicare from 12 months before to 84 months after diagnosis. Two comorbidity indices were constructed: the National Cancer Institute index, using 12 months of claims before cancer, and a second index for previously undetected conditions, using three months after cancer. Conditions present in the first were excluded from the second. Overall, 6,184 (10.1% had ≥1 undetected comorbidity. Chronic obstructive pulmonary disease (38% was the most common undetected condition. In multivariable analyses that adjusted for comorbidity detected before cancer, older age, later stage, higher grade, and poor performance status all were associated with higher odds of ≥1 undetected comorbidity. In stage I–III cancer, undetected comorbidity was associated with lower adjusted odds of receiving adjuvant chemotherapy (Odds Ratio (OR = 0.81, 95% Confidence Interval (CI 0.73–0.90, P<0.0001; OR=0.38, 95% CI 0.30–0.49, P<0.0001; index score 1 or ≥2, respectively, and with increased mortality (Hazard Ratio (HR = 1.45, 95% CI 1.38–1.53, P<0.0001; HR=2.38, 95% CI 2.18–2.60, P<0.0001; index score 1 or ≥2. Undetected comorbidity is associated with less aggressive treatment and higher mortality in breast cancer.

    Full Text Available Summary: Outcome studies help provide the evidence-based science rationalizing treatment end results that factor the experience of patients and the impact on society. They improve the recognition of the shortcoming in clinical practice and provide the foundation for the development of gold standard care. With such evidence, health care practitioners can develop evidence-based justification for treatments and offer patients with superior informed consent for their treatment options. Furthermore, health care and insurance agencies can recognize improved cost-benefit options in the purpose of disease prevention and alleviation of its impact on the patient and society. Health care outcomes are ultimately measured by the treatment of disease, the reduction of symptoms, the normalization of laboratory results and physical measures, saving a life, and patient satisfaction. In this review, we outline the tools available to measure outcomes in plastic surgery and subsequently allow the objective measurements of plastic surgical conditions. Six major outcome categories are discussed: (1 functional measures; (2 preference-based measures and utility outcome scores; (3 patient satisfaction; (4 health outcomes and time; (5 other tools: patient-reported outcome measurement information system, BREAST-Q, and Tracking Operations and Outcomes for Plastic Surgeons; and (6 cost-effectiveness analysis. We use breast hypertrophy requiring breast reduction as an example throughout this review as a representative plastic surgical condition with multiple treatments available.

  11. Effect of Family History on Outcomes in Patients Treated With Definitive Brachytherapy for Clinically Localized Prostate Cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the impact familial prostate cancer has on prognosis in men treated with brachytherapy for clinically localized prostate cancer. Methods and Materials: A total of 1,738 consecutive patients with prostate cancer (cT1-3, N0/X, M0) received low-dose-rate brachytherapy alone or in combination with external beam radiation therapy or hormone ablation from 1992 to 2005. The primary end-point was freedom from biochemical failure (FFBF) using the Phoenix definition. Minimum follow-up was 2 years and the median follow-up was 60 months (range, 24-197 months). Results: A total of 187 of 1,738 men (11%) had a family history of prostate cancer in a first-degree relative. For the low-risk patients, both groups had similar actuarial 5-year FFBF (97.2% vs. 95.5%, p = 0.516). For intermediate-risk patients, there was a trend toward improved biochemical control in men positive for family history (5-yr FFBF 100% vs. 93.6%, p = 0.076). For the high-risk patients, men with a positive family history had similar 5-year FFBF (92.8% vs. 85.2%, p = 0.124). On multivariate analysis, family history was not significant; use of hormones, high biologic effective dose, initial prostate-specific antigen value, and Gleason score were the significant variables predicting biochemical control. Conclusions: This is the first study to examine the relationship of familial prostate cancer and outcomed in men treated with brachytherapy alone or in combination therapy. Men with a positive family history have clinicopathologic characteristics and biochemical outcomes similar to those with sporadic disease

    Full Text Available To compare the long-term clinical outcomes of postmastectomy radiotherapy (PMRT between breast cancer patients with and without immediate transverse rectus abdominis myocutaneous (TRAM flap reconstruction.The study included 492 patients with stage II or III breast cancer who underwent modified radical mastectomy (MRM and chemotherapy followed by PMRT between 1997 and 2011. Cox regression model and Kaplan-Meier curves were calculated, and the log-rank test was used to evaluate the differences between overall and disease-free survival rates in the 2 groups.Among 492 patients, 213 patients had immediate TRAM flap reconstruction. The mean follow-up was 7.2 years (range, 11-191 months. The 5-year and 10-year disease free survival rates were 81% and 76% for the TRAM flap group and 78% and 73% for the non-flap group. The 5-year and 10-year overall survival rates were 89% and 73% for the TRAM flap group and 83% and 74% for the non-flap group.There exists no statistically significant difference in the rates of local recurrence, distant metastasis, disease-free and overall survival when comparing immediate TRAM flap reconstruction with no reconstruction. Our results suggest that immediate TRAM flap reconstruction does not compromise long term clinical outcomes in breast cancer patients requiring PMRT.

  15. Dose escalation with three-dimensional conformal radiation therapy affects the outcome in prostate cancer

    International Nuclear Information System (INIS)

    Purpose: Three-dimensional conformal radiation therapy (3D-CRT) is a technique designed to deliver prescribed radiation doses to localized tumors with high precision, while effectively excluding the surrounding normal tissues. It facilitates tumor dose escalation which should overcome the relative resistance of tumor clonogens to conventional radiation dose levels. The present study was undertaken to test this hypothesis in patients with clinically localized prostate cancer. Methods and Materials: A total of 743 patients with clinically localized prostate cancer were treated with 3D-CRT. As part of a phase I study, the tumor target dose was increased from 64.8 to 81 Gy in increments of 5.4 Gy. Tumor response was evaluated by post-treatment decrease of serum prostate-specific antigen (PSA) to levels of ≤1.0 ng/ml and by sextant prostate biopsies performed ≥2.5 years after completion of 3D-CRT. PSA relapse-free survival was used to evaluate long-term outcome. The median follow-up was 3 years (range: 1-7.6 years). Results: Induction of an initial clinical response was dose-dependent, with 90% of patients receiving 75.6 or 81.0 Gy achieving a PSA nadir ≤1.0 ng compared with 76% and 56% for those treated with 70.2 Gy and 64.8 Gy, respectively (p < 0.001). The 5-year actuarial PSA relapse-free survival for patients with favorable prognostic indicators (stage T1-2, pretreatment PSA ≤10.0 ng/ml and Gleason score ≤6) was 85%, compared to 65% for those with intermediate prognosis (one of the prognostic indicators with a higher value) and 35% for the group with unfavorable prognosis (two or more indicators with higher values) (p < 0.001). PSA relapse-free survival was significantly improved in patients with intermediate and unfavorable prognosis receiving ≥75.6 Gy (p < 0.05). A positive biopsy at ≥2.5 years after 3D-CRT was observed in only 1/15 (7%) of patients receiving 81.0 Gy, compared with 12/25 (48%) after 75.6 Gy, 19/42 (45%) after 70.2 Gy, and 13/23 (57

    Full Text Available Abstract Background MED28 (also known as EG-1 and magicin has been implicated in transcriptional control, signal regulation, and cell proliferation. MED28 has also been associated with tumor progression in in vitro and in vivo models. Here we examined the association of MED28 expression with human breast cancer progression. Methods Expression of MED28 protein was determined on a population basis using a high-density tissue microarray consisting of 210 breast cancer patients. The association and validation of MED28 expression with histopathological subtypes, clinicopathological variables, and disease outcome was assessed. Results MED28 protein expression levels were increased in ductal carcinoma in situ and invasive ductal carcinoma of the breast compared to non-malignant glandular and ductal epithelium. Moreover, MED28 was a predictor of disease outcome in both univariate and multivariate analyses with higher expression predicting a greater risk of disease-related death. Conclusions We have demonstrated that MED28 expression is increased in breast cancer. In addition, although the patient size was limited (88 individuals with survival information MED28 is a novel and strong independent prognostic indicator of survival for breast cancer.

  18. Stereotactic body radiotherapy for low-risk prostate cancer: five-year outcomes

    International Nuclear Information System (INIS)

    Hypofractionated, stereotactic body radiotherapy (SBRT) is an emerging treatment approach for prostate cancer. We present the outcomes for low-risk prostate cancer patients with a median follow-up of 5 years after SBRT. Between Dec. 2003 and Dec. 2005, a pooled cohort of 41 consecutive patients from Stanford, CA and Naples, FL received SBRT with CyberKnife for clinically localized, low-risk prostate cancer. Prescribed dose was 35-36.25 Gy in five fractions. No patient received hormone therapy. Kaplan-Meier biochemical progression-free survival (defined using the Phoenix method) and RTOG toxicity outcomes were assessed. At a median follow-up of 5 years, the biochemical progression-free survival was 93% (95% CI = 84.7% to 100%). Acute side effects resolved within 1-3 months of treatment completion. There were no grade 4 toxicities. No late grade 3 rectal toxicity occurred, and only one late grade 3 genitourinary toxicity occurred following repeated urologic instrumentation. Five-year results of SBRT for localized prostate cancer demonstrate the efficacy and safety of shorter courses of high dose per fraction radiation delivered with SBRT technique. Ongoing clinical trials are underway to further explore this treatment approach

  19. The influence of smoking and other risk factors on the outcome after radiochemotherapy for anal cancer

    International Nuclear Information System (INIS)

    Smoking is an important risk factor for the development of cancer. Smoking during radiochemotherapy therapy may have a negative influence on prognosis. We evaluated the effect of smoking during radiochemotherapy on the outcome for patients with anal cancer. Sixty-eight patients (34 smokers, 34 non-smokers) treated by radiochemotherapy for anal cancer were analysed. The effect of smoking during radiochemotherapy and other risk factors (gender, T- and N category, tumor site, dose, therapy protocol) on disease-specific survival (DSS), local control (LC) and colostomy free survival (CFS) was evaluated. There was a significant difference in age and male:female ratio between the two groups. With a median follow up of 22 months (max. 119) DSS, LC, and CFS were 88%, 84% and 84%. A significant difference in local control between smokers (S) and non-smokers (NS) was found (S 74% vs. NS 94%, p = .03). For DSS and CFS a difference in terms of outcome between smokers and non-smokers was seen (DSS: S 82% vs. NS 96%, p = .19, CFS: S 75% vs. 91%, p = .15), which did not reach statistical significance. In multivariate analyses only gender had a significant association with LC and T category with CFS. The other risk factors did not reach statistical significance. Even though our evaluation reached statistical significance only in univariate analysis, we suggest, that the role of smoking during radiochemotherapy for anal cancer should not be ignored. The potential negative effect on prognosis should be explained to patients before therapy

    The importance of intratumour genetic and functional heterogeneity is increasingly recognised as a driver of cancer progression and survival outcome. Understanding how tumour clonal heterogeneity impacts upon therapeutic outcome, however, is still an area of unmet clinical and scientific need. TRACERx (TRAcking non-small cell lung Cancer Evolution through therapy [Rx]), a prospective study of patients with primary non-small cell lung cancer (NSCLC), aims to define the evolutionary trajectories of lung cancer in both space and time through multiregion and longitudinal tumour sampling and genetic analysis. By following cancers from diagnosis to relapse, tracking the evolutionary trajectories of tumours in relation to therapeutic interventions, and determining the impact of clonal heterogeneity on clinical outcomes, TRACERx may help to identify novel therapeutic targets for NSCLC and may also serve as a model applicable to other cancer types.

    CYP3A enzymes metabolize endogenous hormones and chemotherapeutic agents used to treat cancer, thereby potentially affecting drug effectiveness. Here, we refined the genetic basis underlying the functional effects of a CYP3A haplotype on urinary estrone glucuronide (E1G) levels and tested for an association between CYP3A genotype and outcome in patients with chronic lymphocytic leukemia (CLL), breast, or lung cancers. The most significantly associated SNP was rs45446698, an SNP that tags the CYP3A7*1C allele; this SNP was associated with a 54% decrease in urinary E1G levels. Genotyping this SNP in 1,008 breast cancer, 1,128 lung cancer, and 347 CLL patients, we found that rs45446698 was associated with breast cancer mortality (HR, 1.74; P = 0.03), all-cause mortality in lung cancer patients (HR, 1.43; P = 0.009), and CLL progression (HR, 1.62; P = 0.03). We also found borderline evidence of a statistical interaction between the CYP3A7*1C allele, treatment of patients with a cytotoxic agent that is a CYP3A substrate, and clinical outcome (Pinteraction = 0.06). The CYP3A7*1C allele, which results in adult expression of the fetal CYP3A7 gene, is likely to be the functional allele influencing levels of circulating endogenous sex hormones and outcome in these various malignancies. Further studies confirming these associations and determining the mechanism by which CYP3A7*1C influences outcome are required. One possibility is that standard chemotherapy regimens that include CYP3A substrates may not be optimal for the approximately 8% of cancer patients who are CYP3A7*1C carriers.

  6. Clinical complete responders to definite chemoradiation or radiation therapy for oesophageal cancer: predictors of outcome

    International Nuclear Information System (INIS)

    To identify predictors of long-term outcome for patients with clinical complete response (cCR) after definite chemoradiotherapy (CRT) or radiation therapy (RT) for oesophageal cancer (EC). In this retrospective study, we reviewed the files of all patients from our institution that underwent definitive RCT or RT for EC, from January 1998 to December 2003. Among 402 consecutive patients with EC, 110 cCR responses were observed, i.e. without evidence of tumour on morphological examination of the biopsy specimens, 8 to 10 weeks after radiation. Baseline patient and tumour characteristics were as follows: male = 98/110, median age = 60, squamous histology = 103/110, tumour site (upper/middle/lower third) = 41/50/19, weight loss none/<10%/≥10% = 36/45/29, dysphagia grade 1/2/≥3 = 30/14/66. Patients were staged according to endosonography and/or computed tomography. There were 9 stage I, 31 stage IIA, 15 stage IIB, 41 stage III, 6 stage IV. Post treatment nutritional characteristics were as follows: weight loss during treatment none/<10% ≥ 10% = 35/38/37, remaining dysphagia grade 1/2/≥3 = 54/24/32. Univariate and multivariate analyses were performed using log-rank and Cox proportional hazards models, and survival curves were estimated using the Kaplan-Meier method. During follow up (median: 6 [0.4–9.8] years), 16 patients had salvage surgery. Median OS was 2.5 years, and 5-year OS was 33.5%. Histological type, stage, age, gender, and treatment characteristics had no significant impact on outcome. The risk of death was increased two-fold for patients with grade ≥ 3 dysphagia after treament (HR = 1.9 [1.2–3.1], p = 0.007). Weight loss ≥10% during treatment also negatively affected outcome (HR = 1.8 [1.0–3.2], p = 0.040). One EC patient among 3 with cCR after definite CRT/RT is still alive at 5 years. Variables related to reduced OS were: remaining significant dysphagia after treatment and weight loss ≥10% during treatment

    Full Text Available Abstract Introduction Brain-derived neurotrophic factor (BDNF has established physiological roles in the development and function of the vertebrate nervous system. BDNF has also been implicated in several human malignancies, including breast cancer (BC. However, the precise biological role of BDNF and its utility as a novel biomarker have yet to be determined. The objective of this study was to determine the mRNA and protein expression of BDNF in a cohort of women with BC. Expression levels were compared with normal background tissues and evaluated against established pathological parameters and clinical outcome over a 10 year follow-up period. Methods BC tissues (n = 127 and normal tissues (n = 33 underwent RNA extraction and reverse transcription, BDNF transcript levels were determined using real-time quantitative PCR. BDNF protein expression in mammary tissues was assessed with standard immuno-histochemical methodology. Expression levels were analyzed against tumour size, grade, nodal involvement, TNM stage, Nottingham Prognostic Index (NPI and clinical outcome over a 10 year follow-up period. Results Immuno-histochemical staining revealed substantially greater BDNF expression within neoplastic cells, compared to normal mammary epithelial cells.

    Full Text Available Background: most studies that analyze the influence of structure factors on clinical outcomes are retrospective, based on clinical-administrative databases, and mainly focusing on surgical volume. Objective: to study variations in the process and outcomes of oncologic surgery for esophagus, stomach, pancreas, liver metastases and rectum cancers in Catalonia, as well as the factors associated with these variations. Patients and method: a retrospective (2002 and prospective (2003-05 multicenter cohort study. Data forms were designed to collect patient, process, and care outcome characteristics before surgery, at hospital discharge, and at 3 and 6 months after discharge. Main outcome measures were hospital and follow-up mortality, complications, re-interventions, and relapse rates. Results: 49 hospitals (80% participated in the retrospective phase, 44 of which (90% also participated in the prospective phase: 3,038 patients (98% were included. No differences were observed in the profile of operated patients according to hospital level of complexity, but clinical-pathological staging and other functional status variables could not be assessed because of over 20% of missing values. There was significant variability in the volume of interventions as well as in certain aspects of the healthcare process depending on type of cancer and center complexity. High rates of esophageal cancer mortality (18.2% at discharge, 27.3% at 6 months and of complications and re-interventions for all cancers assessed, especially rectal cancer (18.4% re-interventions at 6 months, were identified. Conclusions: the study of the variability identified will require adequate risk-adjustment and should take into account different structure factors. It is necessary that information included in medical records be improved.Antecedentes: la mayoría de estudios que analizan la influencia de factores de estructura sobre los resultados son retrospectivos, realizados con bases de datos

    BACKGROUND: Incisional hernia repair is a frequent surgical procedure, but perioperative risk factors and outcomes have not been prospectively assessed in large-scale studies. The aim of this nationwide study was to analyze surgical risk factors for early and late outcomes after incisional hernia...... primary laparotomy were significant independent risk factors for poor early outcomes (p <0.05). The cumulated risk of recurrence repair after open and laparoscopic repair was 21.1% and 15.5%, respectively (p = 0.03). Younger age, open repair, hernia defects >7 cm, and onlay or intraperitoneal mesh...... positioning in open repair were significant risk factors for poor late outcomes (p <0.05). CONCLUSIONS: Elective incisional hernia repair were beset with high rates of readmission and reoperation for recurrence. Readmission and reoperation for recurrence were most pronounced after open repair and repair for...

    High mobility group AT-hook 2 (HMGA2) is involved in a wide spectrum of biological processes and is upregulated in several tumors. Here, we collected 273 breast cancer (BC) specimens as a training set and 310 specimens as a validation set to examine the expression of HMGA2 by immunohistochemical staining. It was found that HMGA2 expression was significantly positively correlated with advanced tumor grade and poor survival. Subgroup analysis indicated that high level of HMGA2 was significantly correlated with poor prognosis, especially in the subgroups of stage II-III, low pathological grade and non-triple negative breast cancer cases. Gene set enrichment analysis (GSEA) demonstrated a significant positive correlation between HMGA2 level and the gene expression signature of metaplastic and mesenchymal phenotype. Importantly, we also observed that ectopic expression of HMGA2 promoted the migration and invasion of breast cancer cells, and protected cancer cells against genotoxic stress from agents stimulating P53 (Ser15) phosphorylation. As a conclusion, expression of HMGA2 might indicate more advanced malignancy of breast cancer. Thus we believe HMGA2 could serve as a biomarker of poor prognosis and a novel target in treating BC tumors. PMID:27063096

  15. Improving Breast Cancer Outcomes among Women in China: Practices, Knowledge, and Attitudes Related to Breast Cancer Screening

    2012-01-01

    Full Text Available Background. Breast cancer is a major public health issue and the most commonly diagnosed cancer for women worldwide. Despite lower incidence rates than those living in Western countries, breast cancer incidence among Chinese women has increased dramatically in the past 20 years. Nevertheless, there is a paucity of studies reporting the attitudes toward and practices of breast cancer screening among Chinese women. Methods. This cross-sectional study examined the practices, knowledge, and attitudes toward breast cancer screening (BCS on a convenience sample of 400 Chinese women. Results. Among study participants, 75% of the women never had a mammogram and the top three barriers reported were low priority, feeling OK, and lack of awareness/knowledge toward breast cancer screening. The results from the logistic regression model showed increased self-efficacy; having performed monthly self-exams, and having had clinical breast exams in the past two years were significant correlates while demographic variables were not correlated with screening behaviors. Conclusion. The findings provide a foundation to better understand beliefs and practices of Chinese women toward BCS and highlight the critical need for general public, health professionals, and the health care system to work collaboratively toward improving the quality of breast cancer care in this population.

  16. Early results of prostate cancer radiation therapy: an analysis with emphasis on research strategies to improve treatment delivery and outcomes

    International Nuclear Information System (INIS)

    There is scant data regarding disease presentation and treatment response among black men living in Africa. In this study we evaluate disease presentation and early clinical outcomes among Ghanaian men with prostate cancer treated with external beam radiotherapy (EBRT). A total of 379 men with prostate cancer were referred to the National Center for Radiotherapy, Ghana from 2003 to 2009. Data were collected regarding patient-and tumor-related factors such as age, prostate specific antigen (PSA), Gleason score (GS), clinical stage (T), and use of androgen deprivation therapy (ADT). For patients who received EBRT, freedom from biochemical failure (FFbF) was evaluated using the Kaplan-Meier method. Of 379 patients referred for treatment 69.6% had initial PSA (iPSA) > 20 ng/ml, and median iPSA was 39.0 ng/ml. A total of 128 men, representing 33.8% of the overall cohort, were diagnosed with metastatic disease at time of referral. Among patients with at least 2 years of follow-up after EBRT treatment (n=52; median follow-up time: 38.9 months), 3- and 5-year actuarial FFbF was 73.8% and 65.1% respectively. There was significant association between higher iPSA and GS (8–10 vs. ≤7, p < 0.001), and T stage (T3/4 vs. T1/2, p < 0.001). This is the largest series reporting on outcomes after prostate cancer treatment in West Africa. That one-third of patients presented with metastatic disease suggests potential need for earlier detection to permit curative-intent therapy. Data from this study will aid in the strategic development of prostate cancer research roadmap in Ghana

    This systematic review assessed the quantity and quality of research examining the psychosocial outcomes among hematological cancer patients. Studies were categorised as either measurement, descriptive or intervention. Intervention studies were further assessed according to Effective Practice and Organisation of Care (EPOC) methodological criteria. A total of 261 eligible papers were identified. The number of publications increased by 8.8% each year (95% CI=7.5-10.2%; pEPOC design criteria, however only two interventions, one targeted at individuals with Hodgkin's or Non-Hodgkin's lymphoma and one targeted at individuals with leukaemia, lymphoma or myelomatosis were successful in improving patients' psychosocial outcomes. Despite an increasing volume of research examining psychosocial outcomes of hematological cancer patients, there is a need for robust measurement and methodologically rigorous intervention research in this area.

    Background: Increased number of single nucleotide substitutions is seen in breast and ovarian cancer genomes carrying disease-associated mutations in BRCA1 or BRCA2. The significance of these genome-wide mutations is unknown. We hypothesize genome-wide mutation burden mirrors deficiencies in DNA ...... cancer is a genomic marker of prognosis and predictor of treatment response. This marker may reflect the degree of deficiency in BRCA-mediated pathways, or the extent of compensation for the deficiency by alternative echanisms....... repair and is associated with treatment outcome in ovarian cancer. Methods and Results: The total number of synonymous and non-synonymous exome mutations (Nmut), and the presence of germline or somatic mutation in BRCA1 or BRCA2 (mBRCA) were extracted from whole-exome sequences of high-grade serous...... mutations. In cancers with wild-type BRCA, tumor Nmut was associated with treatment response in patients with no residual disease after surgery. Conclusions: Tumor Nmut was associated with treatment response and with both PFS and OS in patients with highgrade serous ovarian cancer carrying BRCA1 or BRCA2...

    2012-02-01

    We examined the outcomes of the first 500 patients referred to a dedicated Rapid Access Lung Cancer Clinic. A total of 206 patients (41.2%) were diagnosed with a thoracic malignancy; 179 had primary lung cancer and 27 had secondary or other thoracic cancers. Pulmonary nodules requiring ongoing surveillance were found in a further 79 patients (15.8%). Of those patients found to have primary lung cancer, 24 (13.4%) had Small Cell and 145 (81%) had Non Small Cell Lung Cancer. In patients with Non small cell tumours, 26 (21.1%) were stage 1, 14 (11.4%) stage II, 37 (30.1%) stage III and 46 (37.4%) stage IV at diagnosis. For the 129 patients (72%) in whom the thoracic MDT recommended active treatment, primary therapy was surgical resection in 44 (24.6%), combined chemoradiation in 31 patients (17.3%), chemotherapy alone in 39 (21.8%) and radiation in 15 (8.4%).

    2013-06-01

    Nonmelanoma skin cancer (NMSC) is the most common malignancy in the western world, with an incidence of 98,000 in the U.K. Since 2009 the Department of Health (DoH) has collected patient-reported outcome measure (PROM) data following four common surgical procedures. However, a DoH PROM for NMSC does not exist. A systematic review of questionnaires published on patient concerns due to NMSC of the face was conducted. Keywords relevant to PROMs, NMSC and the facial region were comprehensively searched in medical databases. Inclusion criteria stipulated that questionnaires from relevant papers recruited patients with NMSC for both the item formulation and subsequent validation. Questionnaires were then discussed by a multispecialty skin cancer research team. Initially 2548 papers were found; after exclusion criteria were applied, 73 articles were retrieved. Four patient questionnaires for NMSC featured adequate development and validation according to the inclusion criteria. The Facial Skin Cancer Index (FSCI) was the only PROM specific to facial NMSC. Additional questionnaires identified included the Skin Cancer Quality of Life Impact Tool, Skindex, and Dermatology Life Quality Index. There is a scarcity of data relating to NMSC PROMs and appearance concerns. Only one questionnaire--the FSCI--was specific to patients with facial NMSC. We recommend nationally standardized data collection from patients with NMSC in order to create an evidence-based validated PROM for patients with facial skin cancer. PMID:23387431

    1997-11-01

    Bioplastique is a biphasic polymer for the permanent augmentation of some soft tissues. It was developed in 1987, and clinical studies at this institution were begun in 1990. The combination of low molecular weight polyvinylpyrrolidone and solid polymer particles allows the implantation of permanent polymer spheres through a small needle under local anesthesia. In this study 127 cases are reviewed of consecutive patients who have received Bioplastique for scar revision, wrinkles, and augmentation for soft-tissue defects at 6 years after application. All patients who had not been in for follow-up recently were contacted by mail and questioned on the permanence of augmentation and migration of particles. About 30 percent of the patients were unreachable and had their charts reviewed for permanence and migration of particles. In eight of these cases, Bioplastique was removed because of overcorrection, two of them may have had infection. Bioplastique has gained wide use throughout the world and although some complications have been reported, in general, it functions quite well when used in selected cases. PMID:9385974

  3. Outcomes and Tolerability of Chemoradiation Therapy for Pancreatic Cancer Patients Aged 75 Years or Older

    International Nuclear Information System (INIS)

    Purpose: To review the outcomes and tolerability of full-dose chemoradiation in elderly patients aged 75 years or older with localized pancreatic cancer. Methods and Materials: We retrospectively reviewed patients aged 75 years or older with nonmetastatic pancreatic cancer treated with chemoradiation therapy at two institutions from 2002 to 2007. Patients were analyzed for treatment toxicity, local recurrences, distant metastases, and survival. Results: A total of 42 patients with a median age of 78 years (range, 75-90 years) who received chemoradiation therapy for pancreatic cancer were identified. Of the patients, 24 had locally advanced disease treated with definitive chemoradiation, and 18 had disease treated with surgery and chemoradiation. Before chemoradiotherapy, the mean Eastern Cooperative Oncology Group performance status was 1.0 ± 0.8, and the mean 6-month weight loss was 5.3 ± 3.8 kg. The mean radiation dose delivered was 48.1 ± 9.2 Gy. All patients received fluoropyrimidine-based chemotherapy concurrently with radiotherapy. In all, 8 patients (19%) were hospitalized, 7 (17%) had an emergency room visit, 15 (36%) required a radiation treatment break, 3 (7%) required a chemotherapy break, 9 (21%) did not complete therapy, and 22 (49%) had at least one of these adverse events. The most common toxicities were nausea, pain, and failure to thrive. Median overall survival was 8.6 months (95% confidence interval, 7.2-13.1) in patients who received definitive chemoradiation therapy and 20.6 months (95% confidence interval, 9.5-∞) in patients who underwent resection and chemoradiation therapy. Conclusions: In this dataset of very elderly patients with pancreatic cancer and good Eastern Cooperative Oncology Group performance status, outcomes after chemoradiotherapy were similar to those among historic controls for patients with locally advanced and resected pancreatic cancer, although many patients experienced substantial treatment-related toxicity.

  4. Outcome and treatment strategy in female lung cancer: a single institution experience

    International Nuclear Information System (INIS)

    Purpose: To assess the survival rate of female lung cancer treated at the Institute of Oncology of the Vilnius University, Lithuania during the period between 1996-2005. Materials and Methods: During the period between 1996-2005, 471 women diagnosed with lung cancer were treated at the Department of Thoracic Surgery and Oncology of the Institute of Oncology, Vilnius University. Data on morphology, stage and treatment was collected from the medical records. All lung cancer cases by histology were classified in two groups: non-small cell lung cancer (includes squamous cell carcinoma, large cell carcinoma, adenocarcinoma and other less common types) and small cell lung cancer. The vital status of the study group was assessed as of December 31, 2007, by passive follow-up, using data from the population registry. It was found that 411 (87.3%) of the patients had died. Survival was estimated according to the Kaplan-Meier method. Results: The median survival of female lung cancer diagnosed during 1996-2005 in Lithuania show to be 8.7 months (8.4 (95% CI 7.2-10.8) months with non-small cell lung cancer and 9.3 (95% CI 6.3-13.0) months with small-cell lung cancer). Survival was more than 20 months in resectable non-small cell lung cancer (stages I, II, IIIA). Non-small cell lung cancer survival in advanced stages was less than 7 months. Small-cell lung cancer patients median survival at limited and extended stages of the disease were 9.5 (95% CI 2.9-18.4) compared to 9.2 (95% CI 6.2-13.7) months. Non-small cell lung cancer patients most frequently were treated by surgery (27.0%), surgery and chemotherapy or radiotherapy (19.6%). Small cell lung cancer patient treatment included chemo and radiotherapy (27.0%), chemotherapy (19.0%), radiotherapy (17.5%), surgery (27.9%). Conclusions: The single center study of female lung cancer diagnosed during 1996-2005 in Lithuania show a significantly better chance of survival in resectable non-small cell lung cancer.

  5. Influence of human papillomavirus and p16INK4a on treatment outcome of patients with anal cancer

    International Nuclear Information System (INIS)

    Background: The purpose of this study was to evaluate HPV-DNA and p16INK4a (p16) expression as prognostic markers for outcome in patients with anal cancer. Methods: From January 2000 to December 2011 a cohort of 105 anal cancer patients was treated with definitive chemoradiation at our institution. Tumor biopsies from 90 patients were analyzed for HPV-DNA by polymerase chain reaction and for p16 expression by immunohistochemistry. Results: Median follow-up was 48.6 months (range 2.8–169.1 months). HPV-DNA or p16-expression was found in 75 anal cancers each (83.3%), concordance was detectable in 70 tumors (77.8%). Significantly improved overall survival (OS) [77.1% vs. 51.4%, p = 0.005], progression-free survival (PFS) [64.0% vs. 35.0%, p < 0.001] and improved local control [81.0% vs. 55.9%, p = 0.023] was found for concomitant HPV- and p16-positive anal carcinomas (cHPPAC) in univariate analysis. Multivariate analysis showed better OS [p = 0.015] and PFS [p = 0.002] for cHPPAC. Conclusion: The combination of HPV-DNA and p16 can be used as an independent prognostic parameter in anal cancer patients

    To evaluate outcome and morbidity in patients with vulvar cancer treated with radiotherapy, concurrent chemoradiotherapy or postoperative radiotherapy. The records of 24 patients treated with radiotherapy for vulvar cancer between July 1993 and September 2009 were retrospectively reviewed. All patients received once daily 1.8-4 Gy fractions external beam radiotherapy to median 51.2 Gy (range, 19.8 to 81.6 Gy) on pelvis and inguinal nodes. Seven patients were treated with primary concurrent chemoradiotherapy, one patient was treated with primary radiotherapy alone, four patients received palliative radiotherapy, and twelve patients were treated with postoperative radiotherapy. Twenty patients were eligible for response evaluation. Response rate was 55% (11/20). The 5-year disease free survival was 42.2% and 5-year overall survival was 46.2%, respectively. Fifty percent (12/24) experienced with acute skin complications of grade III or more during radiotherapy. Late complications were found in 8 patients. 50% (6/12) of patients treated with lymph node dissection experienced severe late complications. One patient died of sepsis from lymphedema. However, only 16.6% (2/12) of patients treated with primary radiotherapy developed late complications. Outcome of patients with vulvar cancer treated with radiotherapy showed relatively good local control and low recurrence. Severe late toxicities remained higher in patients treated with both node dissection and radiotherapy.

  9. Patterns of Utilization of Adjuvant Radiotherapy and Outcomes in Black Women After Breast Conservation at a Large Multidisciplinary Cancer Center

    International Nuclear Information System (INIS)

    Purpose: Population-based studies have reported that as many of 35% of black women do not undergo radiotherapy (RT) after breast conservation surgery (BCS). The objective of the present study was to determine whether this trend persisted at a large multidisciplinary cancer center, and to identify the factors that predict for noncompliance with RT and determine the outcomes for this subset of patients. Methods and Materials: Between January 2002 and December 2007, 83 black women underwent BCS at Memorial Sloan-Kettering Cancer Center and were therefore eligible for the present study. Of the 83 women, 38 (46%) had Stage I, 38 (46%) Stage II, and 7 (8%) Stage III disease. Of the study cohort, 31 (37%) had triple hormone receptor-negative tumors. RT was recommended for 81 (98%) of the 83 patients (median dose, 60 Gy). Results: Of the 81 women, 12 (15%) did not receive the recommended adjuvant breast RT. Nonreceipt of chemotherapy (p = .003) and older age (p = .009) were associated with nonreceipt of RT. With a median follow-up of 70 months, the 3-year local control, locoregional control, recurrence-free survival, disease-free survival, and overall survival rate was 99% (actuarial 5-year rate, 97%), 96% (actuarial 5-year rate, 93%), 95% (actuarial 5-year rate, 92%), 92% (actuarial 5-year rate, 89%), and 95% (actuarial 5-year rate, 91%), respectively. Conclusion: We found a greater rate of utilization adjuvant breast RT (85%) among black women after BCS than has been reported in recent studies, indicating that excellent outcomes are attainable for black women after BCS when care is administered in a multidisciplinary cancer center.

With population aging and increases in survival, the number of CRC survivors is projected to rise dramatically. The time following initial treatment is often described as a period of transition from intensive hospital-based care back into “regular life.” This review provides an overview of recommended follow-up care for people with CRC who have been treated with curative intent, as well as exploring the current state of the research that underpins these guidelines. For patients, key concerns following treatment include the development of recurrent and new cancers, late and long-term effects of cancer and treatment, and the interplay of these factors with daily function and general health. For physicians, survivorship care plans can be a tool for coordinating the surveillance, intervention, and prevention of these key patient concerns. Though much of the research in cancer survivorship to date has focused on surveillance for recurrent disease, many national guidelines differ in their conclusions about the frequency and timing of follow-up tests. Most CRC guidelines refer only briefly to the management of side effects, despite reports that many patients have a range of ongoing physiological, psychosocial, and functional needs. Guidance for surveillance and intervention is often limited by a small number of heterogeneous trials conducted in this patient group. However, recently released survivorship guidelines emphasize the potential for the effectiveness of

    2007-03-01

    Breast cancer is the second leading cause of cancer deaths amongst women in the United States. In the past two decades, the potential of non-ionizing high power RF waves to destroy cancerous biological tissues is actively investigated for cancer therapy. This paper presents the computational feasibility study of an alternative mode of electromagnetic radiation therapy that employs dual source and deformable mirror. The adaptive focusing capability of the deformable mirror is exploited for preferential energy deposition at the tumor site in the breast irradiated by electromagnetic radiation. The outcome of the computational study for the proposed deformable mirror-based thermal therapy for breast cancer is presented in this paper.

  15. Stress associated gene expression in blood cells is related to outcome in radiotherapy treated head and neck cancer patients

    International Nuclear Information System (INIS)

    We previously observed that a radiotherapy-induced biochemical response in plasma was associated with favourable outcome in head and neck squamous carcinoma cancer (HNSCC) patients. The aim of the present study was to compare stress associated blood cell gene expression between two sub-groups of HNSCC patients with different biochemical responses to radiotherapy. Out of 87 patients (histologically verified), 10 biochemical ‘responders’ having a high relative increase in plasma oxidative damage and a concomitant decrease in plasma antioxidants during radiotherapy and 10 ‘poor-responders’ were selected for gene-expression analysis and compared using gene set enrichment analysis. There was a significant induction of stress-relevant gene-sets in the responders following radiotherapy compared to the poor-responders. The relevance of the involvement of similar stress associated gene expression for HNSCC cancer and radioresistance was verified using two publicly available data sets of 42 HNSCC cases and 14 controls (GEO GSE6791), and radiation resistant and radiation sensitive HNSCC xenografts (E-GEOD-9716). Radiotherapy induces a systemic stress response, as revealed by induction of stress relevant gene expression in blood cells, which is associated to favourable outcome in a cohort of 87 HNSCC patients. Whether these changes in gene expression reflects a systemic effect or are biomarkers of the tumour micro-environmental status needs further study.

  17. The impact of race on biochemical outcome in patients receiving irradiation for prostate cancer

    International Nuclear Information System (INIS)

    Purpose/Objective: African-Americans tend to present with a higher stage and grade prostate cancer than whites and hence previous studies have attempted to delineate the importance of race in outcome with radiotherapy. However, these studies have had limitations including insufficient number of African-American patients, lack of a similar quality of care or uniform treatment policy. In addition, race as a prognostic variable has not been analyzed in regards to PSA based outcome criteria. The current study was performed in order to determine the impact of race on survival and biochemical control in patients with prostate cancer treated at a single center using a standardized radiation protocol. Materials and Methods: Between 1988 and 1995, 455 patients with clinically localized adenocarcinoma of the prostate received external beam irradiation for a median dose of 68 Gy using a four field technique. Of the 455 patients, 211 were African-American and 244 were white. Pretreatment PSA were: 0-4 ng/ml (51), 4-10 ng/ml (129), 10-20 ng/ml (117), > 20 ng/ml (136), unknown (22). Clinical stages were: T1 (108), T2 (238), T3 (99), not available (10). There was no significant difference in pretreatment characteristics (stage, grade and PSA) or radiation dose between the African-American and white group of patients. Median follow-up is 37.8 months. Biochemical failure was defined as two or more consecutive PSA values that are greater than the posttreatment nadir. Race, pretreatment PSA, grade, age, stage and dose were assessed with univariate and multivariate Cox regression analysis as prognostic factors for overall survival and biochemical disease free survival. Results: The 5 year actuarial overall survival (OS) was 79% and biochemical disease free survival (bNED) was 35% for the entire group of patients. There was no significant difference in 5 year OS (71% vs. 85%) (p=0.3) or bNED (26% vs. 40%) (p=0.26) for African-Americans in comparison to whites. Univariate analysis

  18. Tumor stromal vascular endothelial growth factor A is predictive of poor outcome in inflammatory breast cancer

    International Nuclear Information System (INIS)

    Inflammatory breast cancer (IBC) is a highly angiogenic disease; thus, antiangiogenic therapy should result in a clinical response. However, clinical trials have demonstrated only modest responses, and the reasons for these outcomes remain unknown. Therefore, the purpose of this retrospective study was to determine the prognostic value of protein levels of vascular endothelial growth factor (VEGF-A), one of the main targets of antiangiogenic therapy, and its receptors (VEGF-R1 and -R2) in IBC tumor specimens. Specimens from IBC and normal breast tissues were obtained from Algerian patients. Tumor epithelial and stromal staining of VEGF-A, VEGF-R1, and VEGF-R2 was evaluated by immunohistochemical analysis in tumors and normal breast tissues; this expression was correlated with clinicopathological variables and breast cancer-specific survival (BCSS) and disease-free survival (DFS) duration. From a set of 117 IBC samples, we evaluated 103 ductal IBC tissues and 25 normal specimens. Significantly lower epithelial VEGF-A immunostaining was found in IBC tumor cells than in normal breast tissues (P <0.01), cytoplasmic VEGF-R1 and nuclear VEGF-R2 levels were slightly higher, and cytoplasmic VEGF-R2 levels were significantly higher (P = 0.04). Sixty-two percent of IBC tumors had high stromal VEGF-A expression. In univariate analysis, stromal VEGF-A levels predicted BCSS and DFS in IBC patients with estrogen receptor-positive (P <0.01 for both), progesterone receptor-positive (P = 0.04 and P = 0.03), HER2+ (P = 0.04 and P = 0.03), and lymph node involvement (P <0.01 for both). Strikingly, in a multivariate analysis, tumor stromal VEGF-A was identified as an independent predictor of poor BCSS (hazard ratio [HR]: 5.0; 95% CI: 2.0-12.3; P <0.01) and DFS (HR: 4.2; 95% CI: 1.7-10.3; P <0.01). To our knowledge, this is the first study to demonstrate that tumor stromal VEGF-A expression is a valuable prognostic indicator of BCSS and DFS at diagnosis and can therefore be used to

  19. Is there a difference in outcome between stage I-II endometrial cancer of papillary serous/clear cell and endometrioid FIGO Grade 3 cancer?

    International Nuclear Information System (INIS)

    Purpose: Several reports in the literature have shown that, compared with endometrioid adenocarcinoma, patients with papillary serous (PS) and clear cell (CC) histologic features do worse. However, it is unclear whether the outcome of PS/CC cancer is different from that of poorly differentiated endometrioid cancer. The purpose of this study was to compare the outcome between PS/CC and endometrioid International Federation of Gynecology and Obstetrics (FIGO) Grade 3 cancer and was limited to patients with Stage I-II uterine carcinoma. Methods and Materials: Between November 1987 and September 1999, 83 patients with Stage I endometrial cancer and Stage II occult endometrial cancer were treated with simple hysterectomy and high-dose-rate intravaginal brachytherapy. Forty-one patients (49%) had FIGO Grade 3 endometrioid tumors (Group 1) and 42 (51%) had PS/CC histologic features (Group 2). The mean age was 63 years (range 30-89). Comprehensive surgical staging was done in 23 (28%) of 83 patients. Capillary space-like invasion (CSLI) was seen in 24 (29%) of 83 patients. The median dose of intravaginal brachytherapy when used alone was 21 Gy in 3 fractions. Additional external beam radiotherapy was given to 42 (51%) of 83 patients to 45 Gy. The two groups were balanced with regard to age, race, comprehensive surgical staging, amount of myometrial involvement, CSLI, lower uterine segment involvement, cervical involvement, and use of external beam radiotherapy. The median follow-up was 46 months (range 4-147). Results: The pattern of relapse was as follows: vagina/pelvis in 5 of 14 patients, lungs in 8 of 15, intra-abdominal in 4 of 12, and supraclavicular lymph nodes in 1 of 14. One of the four intra-abdominal disseminations was in Group 1 and the other three in Group 2 (p=0.6). The 5-year vaginal/pelvic control, disease-free survival (DFS), and overall survival (OS) rate was 93% (95% confidence interval [CI] 87-99%), 79% (95% CI 69-89%), and 74% (95% CI 64

  7. The Impact of Radiation Dose and Fractionation on Outcomes for Limited-Stage Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To review the treatment outcomes of limited-stage small-cell lung cancer (LS-SCLC) patients and to compare the outcomes among three groups in which the total radiation doses were 45 Gy with accelerated hyperfractionation (AHF), <54 Gy with standard fractionation (SF), and ≥54 Gy with SF. Methods and Materials: LS-SCLC patients that had been treated with chemoradiotherapy between 1997 and 2007 at Aichi Cancer Center Hospital were reviewed in this study. Of the 127 eligible patients, there were 37 patients in the AHF group, 29 in the SF <54 Gy group, and 61 in the SF ≥54 Gy group. Results: Fifty-five patients (43%) were alive at the time of this analysis, and the median follow-up time of the surviving patients was 33 months. The median survival times were 30.0 months (95% confidence interval [CI] 16.3-43.7) for the AHF group, 14.0 months (CI 6.6-21.4) for the SF <54 Gy group, and 41.0 months (CI 33.9-48.1) for the SF ≥ 54 Gy group. As for the local control rates, and the overall and progression-free survival rates, all outcomes were significantly lower in the SF <54 Gy group than in the other two groups, although no significant difference was found between the AHF and SF ≥54 Gy groups. Conclusions: These results suggest the importance of a high dose of radiation when using once-daily regimen. This study will support future prospective studies to establish optimal radiation doses and fractionation.

  8. Voice and swallowing outcomes of an organ-preservation trial for advanced laryngeal cancer

    International Nuclear Information System (INIS)

    Introduction: Organ-preservation treatment approaches for advanced laryngeal cancer patients that use combination chemoradiotherapy result in cure rates similar to primary laryngectomy with postoperative radiotherapy. In the national VA Larynx Cancer Trial, successful organ preservation was associated with an overall improvement in quality of life but not in subjective speech compared with long-term laryngectomy survivors. As part of a Phase II clinical trial, a prospective study of speech and swallowing results was conducted to determine if larynx preservation is associated with improved voice and swallowing compared with results in patients who require salvage laryngectomy. Subjects: A total of 97 patients with advanced laryngeal cancer (46 Stage III, 51 Stage IV) were given a single course of induction chemotherapy (cisplatin 100 mg/m2 on Day 1 and 5-FU 1,000 mg/m2/day x 5 days), followed by assessment of response. Patients with less than 50% response underwent early salvage laryngectomy, and patients with 50% or better response underwent concurrent chemoradiation (72 Gy and cisplatin 100 mg/m2 on Days 1, 22, and 43), followed by two cycles of adjuvant chemotherapy (DDP/5-FU). Direct laryngoscopy and biopsy were performed 8 weeks after radiation therapy to determine final tumor response. Late salvage surgery was performed on patients with persistent or recurrent disease. Methods: Completed survey data on voice and swallowing utilizing the Voice-Related Quality of Life Measure (V-RQOL) and the List Performance Status Scale for Head and Neck Cancer Patients (PSS-HN) were obtained from 56 patients who were alive and free of disease at the time of survey, with a minimum follow-up of 8 months. Comparisons were made between patients with an intact larynx (n = 37) vs. laryngectomy (n = 19), as well as early (n = 12) vs. late salvage laryngectomy (n = 7). Multivariate analysis was performed to determine factors predictive of voice and swallowing outcomes. Overall 3-year

    Although many clinical and molecular markers for predicting outcomes in bladder cancer (BC) have been reported, their application in clinical practice remains unclear. Bladder carcinogenesis has two distinct molecular pathways that direct the development of BC. FGFR3 mutations are common in low-grade BC, while TP53 mutation or loss of RB1 is associated with muscle-invasive BC. However, no tissue-based gene markers confirmed by prospective large-scale trials in BC have been used in clinical pr...

    Purpose Dermatologic adverse events (dAE) in cancer treatment are frequent with use of targeted therapies. These dAEs have been shown to have significant impact on health-related quality of life (HRQoL). While standardized assessment tools have been developed for physicians to assess severity of dAEs, there is a discord between objective and subjective measures. The identification of patient-reported outcome (PRO) instruments useful in the context of targeted cancer therapies is therefore important in both the clinical and research settings for the overall evaluation of dAEs and their impact on HRQoL. Methods A comprehensive, systematic literature search of published articles was conducted by two independent reviewers in order to identify PRO instruments previously utilized in patient populations with dAEs from targeted cancer therapies. The identified PRO instruments were studied to determine which HRQoL issues relevant to dAEs were addressed, as well as the process of development and validation of these instruments. Results Thirteen articles identifying six PRO instruments met the inclusion criteria. Four instruments were general dermatology (Skindex-16©, Skindex-29©, Dermatology Life Quality Index [DLQI], and DIELH-24), and two were symptom-specific (Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitors-18 [FACT-EGFRI-18] and Hand-Foot Syndrome 14 [HFS-14]). Conclusions While there are several PRO instruments that have been tested in the context of targeted cancer therapy, additional work is needed to develop new instruments and to further validate the instruments identified in this study in patients receiving targeted therapies.

  12. Adaptive Radiotherapy for Head-and-Neck Cancer: Initial Clinical Outcomes From a Prospective Trial

    International Nuclear Information System (INIS)

    Purpose: To present pilot toxicity and survival outcomes for a prospective trial investigating adaptive radiotherapy (ART) for oropharyngeal squamous cell carcinoma. Methods and Materials: A total of 24 patients were enrolled in an institutional review board–approved clinical trial; data for 22 of these patients were analyzed. Daily CT-guided setup and deformable image registration permitted serial mapping of clinical target volumes and avoidance structures for ART planning. Primary site was base of tongue in 15 patients, tonsil in 6 patient, and glossopharyngeal sulcus in 1 patient. Twenty patients (91%) had American Joint Committee on Cancer (AJCC) Stage IV disease. T stage distribution was 2 T1, 12 T2, 3 T3, 5 T4. N stage distribution was 1 N0, 2 N1, 5 N2a, 12 N2b, and 2 N2c. Of the patients, 21 (95%) received systemic therapy. Results: With a 31-month median follow-up (range, 13–45 months), there has been no primary site failure and 1 nodal relapse, yielding 100% local and 95% regional disease control at 2 years. Baseline tumor size correlated with absolute volumetric treatment response (p = 0.018). Parotid volumetric change correlated with duration of feeding tube placement (p = 0.025). Acute toxicity was comparable to that observed with conventional intensity-modulated radiotherapy (IMRT). Chronic toxicity and functional outcomes beyond 1 year were tabulated. Conclusion: This is the first prospective evaluation of morbidity and survival outcomes in patients with locally advanced head-and-neck cancer treated with automated adaptive replanning. ART can provide dosimetric benefit with only one or two mid-treatment replanning events. Our preliminary clinical outcomes document functional recovery and preservation of disease control at 1-year follow-up and beyond.

  14. Impact of early diagnosis of breast cancer on treatment and outcome

    International Nuclear Information System (INIS)

    The detection of non-palpable and small breast cancers by mammography in asymptomatic women is the really decisive contribution of medical imaging to the treatment and outcome of this by far most common malignant tumor in females. Early detection of the disease not only leads to a significant increase in overall cure rates, but also offers patients the enormous advantage of conservative therapy (conservation surgery and radiotherapy), which practically yields the same long-term results as mutilating radical operations. In the past decade a marked increase in early stages of breast cancer has occured. According to the established selection criteria for conservative treatment, over 70% of all newly diagnosed patients would therefore be candidates for this treatment modality. More than 80% are likely to have excellent cosmetic results. For precision radiotherapy of women with breast cancer, individual pretreatment tomographies (computerized tomograpy or transversal analog tomography) should be obtained for treatment planning in exactly the position to be used for subsequent radiotherapy. Useful images for this purpose can only be recorded in the planning unit of a radiotherapy center. Diagnostic procedures for staging of breast cancer will be discussed as well as the problems of locoregional recurrences and follow-up mammographies after conservative treatment. (Author)

    Full Text Available Introduction. Triple negative breast cancer (TNBC is biologically aggressive and is associated with a worse prognosis. To understand the impact of race/ethnicity on outcome for patients with TNBC, confounding factors such as socioeconomic status (SES need to be controlled. We examined the impact of race/ethnicity on a cohort of patients of low SES who have TNBC. Methods. 786 patients with Stage 0–III breast cancer were evaluated. Of these, 202 patients had TNBC (26%. Primary endpoints were cancer recurrence and death. ZIP code-based income tract and institutional financial data were used to assess SES. Data were analyzed using Kaplan-Meier survival analysis, log-rank tests, Cox Proportional hazard regression, chi square test, and t-tests. A P value ≤0.05 was considered statistically significant. Results. Of the 468 African-Americans (60% in the database, 138 had TNBC; 64 of 318 Caucasians had TNBC. 80% of patients had an annual income of ≤$20,000. The 5-year overall survival was 77% for African-American women versus 72% for Caucasian women (=0.95. On multivariate analysis, race/ethnicity had an impact on disease-free survival (=0.027 but not on overall survival (=0.98. Conclusion. In a predominantly indigent population, race/ethnicity had no impact on overall survival for patients with triple negative breast cancer.
