    Patients suffering from intra-capsular prostate cancer (T1-2, N0, M0) are potential candidates for curative treatment by radical prostatectomy or radiation therapy. Curative intended therapy is frequently associated with substantial side effects, which makes accuracy of preoperative staging important. However, up to 40% of the patients with clinically localized disease turn out to be under-staged and should not have been subjected to curative surgery. The aim of this study was to assess the value of preoperative phased array MRI staging in patients who are candidates for radical prostatectomy. Ninety-five potential candidates for radical prostatectomy suspected of suffering from clinical prostate cancer underwent pre-diagnostic and pre-operative staging by magnetic resonance imaging (MRI). The results were compared with the postoperative pathological findings including evidence of extra-capsular extension (ECE) of the tumor. The MRI results were not taken into consideration when staging the patients preoperatively or offering treatment. Radical prostatectomy was performed within a few weeks after MRI. In 48 patients the diagnostic biopsy did not detect carcinoma but benign hyperplasia of the prostate (BPH), while 9 patients had T3 disease. Thirty-eight patients had clinically localized prostate cancer and underwent radical prostatectomy. In 16 cases (42%) ECE was postoperatively proven by the pathologist, while only 22 (58%) of the patients suffered from true localized prostate cancer. The sensitivity and specificity of MRI detecting ECE were 24% and 86% respectively, while the positive and negative predictive value of MRI with regard to ECE were only 57% and 61% respectively. Phased array MRI did not in its present form provide the necessary accuracy in preoperative staging in clinically localized prostate cancer patients.

    Full Text Available Staging is of the utmost importance in the evaluation of a patient with non-small cell lung cancer (NSCLC because it defines the actual extent of the disease. Accurate staging allows multidisciplinary oncology teams to plan the best surgical or medical treatment and to predict patient prognosis. Based on the recommendation of the International Association for the Study of Lung Cancer (IASLC, a tumor, node, and metastases (TNM staging system is currently used for NSCLC. Clinical staging (c-TNM is achieved via non-invasive modalities such as examination of case history, clinical assessment and radiological tests. Pathological staging (p-TNM is based on histological examination of tissue specimens obtained with the aid of invasive techniques, either non-surgical or during the intervention. This review is a critical evaluation of the roles of current pre-operative staging modalities, both invasive and non-invasive. In particular, it focuses on new techniques and their role in providing accurate confirmation of patient TNM status. It also evaluates the surgical-pathological staging modalities used to obtain the true-pathological staging for NSCLC.

    Prostatic carcinoma (PCa) is a significant cause of cancer morbidity and mortality worldwide. Accurate staging is critical for prognosis assessment and treatment planning for PCa. Despite the large volume of clinical activity and research, the challenge to define the most appropriate and clinically relevant staging system remains. The pathologically complex and uncertain clinical course of prostate cancer further complicates the design of staging classification and a substaging system suitable for individualized care. This review will focus on recent progress and controversial issues related to prostate cancer staging. The 2010 revision of the American Joint Committee on Cancer/Union Internationale Contre le Cancer (AJCC/UICC) tumour, node and metastasis (TNM) system is the most widely used staging system at this time. Despite general acceptance of the system as a whole, there is controversy and uncertainty about its application, particularly for T2 subclassification. The three-tiered T2 classification system for organ-confined prostate cancer is superfluous, considering the biology and anatomy of PCa. A tumour size-based substaging system may be considered in the future TNM subclassification of pT2 cancer. Lymph node status is one of the most important prognostic factors for prostate cancer. Nevertheless, clinical outcomes in patients with positive lymph nodes are variable. Identification of patients at the greatest risk of systemic progression helps in the selection of appropriate therapy. The data suggest that the inherent aggressiveness of metastatic prostate cancer is closely linked to the tumour volume of lymph node metastasis. We recommend that a future TNM staging system should consider subclassification of node-positive cancer on the basis of nodal cancer volume, using the diameter of the largest nodal metastasis and/or the number of positive nodes.

    Full Text Available BACKGROUND: IGFBP-3 is a multifunctional protein that inhibits growth and induces apoptosis of cancer cells. Hypermethylation of the promoter represses expression of the IGFBP-3 gene. We undertook this study to assess the impact of IGFBP-3 methylation on survival of early stage gastric cancer patients. METHODS: Of the 482 tissue samples from gastric cancer patients who underwent curative surgery, IGFBP-3 methylation was tested in 138 patients with stage IB/II gastric cancer. We also analyzed IGFBP-3 methylation in 26 gastric cancer cell lines. IGFBP-3 methylation was evaluated by methylation-specific polymerase chain reaction (MethyLight. Statistical analyses, all two-sided, were performed to investigate the prognostic effects of methylation status of the IGFBP-3 promoter on various clinical parameters. RESULTS: Hypermethylation of IGFBP-3 was observed in 26 (19% of the 138 stage IB/II gastric cancer patients. Clinicopathological factors such as age, Lauren classification, sex, tumor infiltration, lymph node metastasis, and histologic grade did not show a statistically significant association with the methylation status of the IGFBP-3 promoter. Patients with a hypermethylated IGFBP-3 promoter had similar 8-year disease-free survival compared with those without a hypermethylated IGFBP-3 promoter (73% vs 75%, P = .78. In subgroup analyses, females, but not males, seemed to have poorer prognosis for DFS and OS in the subset of patients with IGFBP-3 methylation as compared with those without IGFBP-3 methylation (8-year DFS: 55.6% vs 71.6%, P = .3694 and 8-year overall survival: 55.6% vs 68.4%, P = .491, respectively even with no statistical significance. CONCLUSIONS: The status of IGFBP-3 methylation as measured by methylation-specific polymerase chain reaction proposed the modest role for predicting survival in specific subgroups of patients with early-stage gastric cancer who undergo curative surgery. However, this needs further investigation.

    Introduction: The utility of T2-weighted magnetic resonance imaging (MRI) in the local staging of prostate cancer is controversial. Due to the success of multiparametric MRI in cancer localization, there is renewed interested in MRI (± functional sequences) for local staging. Guidance on pre-treatment local staging of prostate cancer by MRI was developed using systematic review methodology and expert consultation. Methods: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and other databases were searched to identify studies comparing: (1) MRI staging vs. radical prostatectomy staging on diagnostic accuracy outcomes; and (2) MRI staging vs. routine clinical staging on clinical and patient outcomes. Studies meeting inclusion criteria were synthesized by outcome and sensitivity/specificity analysis by tumour location was performed. Evidence quality of included studies was assessed and considered in recommendation formulation. Results: The literature search identified 2510 citations; 62 studies were included. Analysis of MRI ≥1.5 T plus endorectal coil (ER) (± functional sequences) in the detection of extraprostatic extension or seminal vesicle invasion showed modest sensitivities (≥50%) and excellent specificities (>85%) among patients scheduled for radical prostatectomy. MRI upstaging was shown in 20/21 studies, with large variation in correctness (11–85%). Scarcity of clinical and patient outcomes among studies limited synthesis and evaluation. Quality assessment found non-trivial biases. Conclusions: Modest imaging performance was shown for MRI (1.5 T + ER and 3 T ± ER) ± functional sequences in regards to sensitivity. Limitations in study design, reporting of clinical and patient outcomes, and the heterogeneous use of MRI tempered the strength of the recommendations.

    Our department has been treating patients with tongue cancer since 1946. Until the early 1980s, treatment for primary lesions consisted mainly of a small dose of radium irradiation, regardless of the clinical stage. The approximate 5-year survival rate for progressive tongue cancer with a staging of greater than T 3 was as low as 20.3% (N=137) between 1946 and 1970. Irradiation methods have since improved, and the resection-reconstruction method using a deltopectral skin flap had been introduced. In addition, a trend has emerged towards performing surgical treatment and reconstructions using a greater pectoral muscle skin flap. As a result, the approximate 5-year survival rate for T 3+T 4 tongue cancer improved to 37.0% (N=40) for the period between 1971 and 1980. In 1982, a reconstruction technique using a free skin flap with the goal of reconciling the preservation of function and an improvement in the clinical results was established. Treatment protocols have changed drastically since then, making it possible to perform an extended resection while maintaining the swallowing function. As a result, the approximate 5-year survival rate for T 3+T 4 tongue cancer has improved to 51.6% (N=126). This paper describes the clinical outcome for stage III and IV progressive tongue cancerstreated mainly by surgery over the past twenty years. The subjects included 192 cases of stage III or IV squamous cell carcinoma of the tongue; all of the subjects underwent radical operations between January 1981 and December 1999. The approximate 5-year survival rate (disease-specific survival rate) for stage III cancers was 65.3% (71.8%) (N=123), while that for stage IV cancers was 38.2% (40.0%) (N=69). The 5-year primary lesion control rate according to T classification was as follows: T 1, 100%, T 2, 83.8%, T 3, 81.7%; and T 4, 77.4%. The 5-year neck control rate was 77.1%. Our department, in principle, usually administers external irradiation at a dosage of 40 Gy. We histologically

    To identify potential biomarkers related with lung cancer metastasis, conditional media (CM) proteins collected from a primary non-small cell lung cancer (NSCLC) cell line NCI-H226 and its brain metastatic subline H226Br were analyzed by one-dimensional electrophoresis (1-D PAGE) and matrix-assisted laser desorption/time of flight mass spectrometry (MALDI-TOF-MS). Twelve biomarkers were identified, of which l-lactate dehydrogenase B (LDHB) chain was significantly up-regulated in the CM of H226Br cell and was further validated in 105 lung cancer, 93 non-lung cancer, 41 benign lung disease, as well as 65 healthy individuals sera using enzyme-linked immunosorbent assay (ELISA). It was found that the levels of LDHB were specifically elevated in NSCLC sera compared with other groups and were progressively increased with the clinical stage. At the cutoff point 0.260 (OD value) on the receiver operating characteristic (ROC) curve, LDHB could comparatively discriminate lung cancer from benign lung disease and healthy control groups with sensitivity 81%, specificity 70% and total accuracy 76%. These findings demonstrated that secretome could open up a possibility to find, identify, and characterize novel biomarkers related with invasion and metastasis. PMID:16890323

HER2 amplification and hyperactivation drive the growth and survival of breast cancers through the aberrant activation of proto-oncogenic signaling systems, particularly the Ras/MAP kinase and PI3K/AKT pathways. Although HER2-positive (HER2+ breast cancer was originally considered to be a highly aggressive form of the disease, the clinical landscape of HER2+ breast cancers has literally been transformed by the approval of anti-HER2 agents for adjuvant and neoadjuvant settings. Indeed, pertuzumab is a novel monoclonal antibody that functions as an anti-HER2 agent by targeting the extracellular dimerization domain of the HER2 receptor; it is also the first drug to receive an accelerated approval by the US Food and Drug Administration for use in neoadjuvant settings in early-stage HER2+ breast cancer. Here, we review the molecular and cellular factors that contribute to the pathophysiology of HER2 in breast cancer, as well as summarize the landmark preclinical and clinical findings underlying the approval and use of pertuzumab in the neoadjuvant setting. Finally, the molecular mechanisms operant in mediating resistance to anti-HER2 agents, and perhaps to pertuzumab as well, will be discussed, as will the anticipated clinical impact and future directions of pertuzumab in breast cancer patients.

    Of 1,486,984 new cancers registered in the Czech Cancer Registry in 1976-2005, 290,312 (19.5%) were multiple malignant neoplasms (MMNs), of which there were 65,292 primary and 89,796 subsequent cases in men and 59,970 primary and 75,254 subsequent cases in women. The duplicities were higher in women, and the triplicities and others (3–6 MMNs) were higher in men. The most frequent diagnoses were the primary cancers of skin, gastrointestinal and urinary tract, male genital organs, respiratory tract in men, and cancers of skin, breast, female genital organs, and gastrointestinal tract in women. The analysis of the early and advanced clinical stages shows that the number of subsequent advanced stages increased after primary advanced stages. Their time-age-space distributions visualized maps of MMNs in 14 Czech regions. These results support the improvement of algorithms of dispensary care for the early detection of the subsequent neoplasms. PMID:23936674

  19. The preliminary clinical application of PET/CT on the diagnosis and staging of lung cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical value of PET/CT on the diagnosis and staging of lung cancer. Methods: 46 lung cancer patients including 35 pre-treatment and 11 post-treatment cases. PET/CT fusion images, PET images and CT images of the same patient were analyzed frame by frame. Results: 1) The sensitivity of PET/CT in 35 pre-treated cases reached 100%. Except one case of alveolar carcinoma showed a diffuse uptake in both lungs, the other patients displayed as hypermetabolic nodular or mass lesions with the size around 0.8-9.4 cm and the standardized uptake value (SUV) 4.6 ± 1.94. The position of hypermetabolic lesion of PET finding were all concordant to CT. PET/CT was superior to PET and CT in final diagnosis, delineating the border, detecting tumor invasion and in differentiating lung cancer from atelectasis, obstructive pneumonitis and pleural effusion. Among 11 post-treated cases, no malignancy was seen in 9 cases and in two cases with metastases in both lungs, the lesions were detected definitely by PET/CT. 2)For the staging, PET/CT was also superior to PET and CT alone with the sensitivity of 95.2%(PET/CT), 90.4%(PET), 73.8%(CT) respectively. PET and CT were complemental each other in the detection of the lesions. Obviously, PET was superior to CT in detection of small lymph node metastases, pleura, bone and adrenal metastases. CT was better than PET in detection of small lung metastases. Conclusions: PET/CT is superior to PET and CT alone in the diagnosis and staging of lung cancer. PET and CT can complement each other.

There is an urgent need for non-surgical prevention and treatment strategies for these patients who fail to respond to progesterone treatment and wish to preserve their fertility. Recently, we have reported that the combined treatment with metformin and progesterone-based oral contraceptives has successfully reversed the early-stage EC into normal endometria in addition to improvement of insulin resistance in women with PCOS. More importantly, one of these treated women has successfully delivered a healthy newborn baby. However, before such treatment can be recommended to the clinical practice, the molecular basis of metformin in the endometrium under physiological and pathological conditions must be elucidated.

    Full Text Available Abstract Background Breast cancer in the Middle-East occurs in relatively young women and frequently presents as advanced disease. A protective effect of multiparity is not apparent, and high familial risk is reported in some countries. This study investigates breast cancer rates and clinical stage related to age in the Kurdish region of Iraq and evaluates risk associated with parity and family history. Findings are compared with nearby countries and the West. Methods Sulaimaniyah Directorate of Health records identified 539 women diagnosed with breast cancer during 2006-2008. Clinical survey forms were completed on 296 patients and on 254 age-matched controls. Age specific incidence rates were calculated from Directorate of Health population estimates. Results Average patient age was 47.4 ± 11 years and 59.5% were pre-menopausal. Diagnosis was at clinical stage 1 for 4.1%, stage 2 for 43.5%, stage 3 for 26.0%, and stage 4 for 8.1% of patients. For 18.2%, stage was unknown. Annual breast cancer incidence rates per 100,000 women peaked at 168.9 at age 55 to 59 and declined to 57.3 at 60 and above. Patients had an average of 5.0 ± 3.3 children compared to 5.4 ± 3.5 for controls, P = 0.16. A first degree family member had breast cancer among 11.1% of patients and 2.1% of controls (P 50% of these patients and controls being ≥50 years old. No statistically significant relationship was found between tumor stage and age, P = 0.59. Conclusions In Kurdish Iraq, breast cancer is predominantly a disease of pre-menopausal women having multiple pregnancies. For younger patients, breast cancer incidence was similar to the West and possibly higher than many Middle-Eastern countries, but unlike the West, the estimated rates declined markedly in the elderly. The familial breast cancer risk for both older and younger women was within the general population risk of Western countries. Clinical stages were advanced and indicated delays in diagnosis that were

    With improved overall survival of cervical cancer patients,the importance of the quality of life (QOL)is increasingly recognized.This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment.We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36) to collect QOL information.Based on SF-36,we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011.A total of 92 patients with precancerous lesions,93 with early cancer,and 35 with advanced cancer responded to our survey.Average physical component summary (PCS) scores were significantly different between the three groups at every time point (P < 0.05).Average mental component summary (MCS) scores were significantly different between the three groups after treatment (P < 0.05).Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions.However,they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1and 6 months after treatment.Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer.Additionally,patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions.Thus,early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.

    Radiation treatment planning for women with locally advanced cervical cancer (stages IB2-IVA) is often based on positron emission tomography (PET). PET, however, has poor sensitivity in detecting metastases in aortocaval nodes. We have initiated a study with the objective of determining whether pre-therapeutic laparoscopic surgical staging followed by tailored chemoradiation improves survival as compared with PET/computed tomography (CT) radiologic staging alone followed by chemoradiation. This international, multicenter phase III trial will enroll 600 women with stages IB2-IVA cervical cancer and PET/CT findings showing fluorodeoxyglucose-avid pelvic nodes and fluorodeoxyglucose-negative para-aortic nodes. Eligible patients will be randomized to undergo either pelvic radiotherapy with chemotherapy (standard-of-care arm) or surgical staging via a minimally invasive extraperitoneal approach followed by tailored radiotherapy with chemotherapy (experimental arm). The primary end point is overall survival. Secondary end points are disease-free survival, short- and long-term morbidity with pre-therapeutic surgical staging, and determination of anatomic locations of metastatic para-aortic nodes in relationship to the inferior mesenteric artery. We believe this study will show that tailored chemoradiation after pre-therapeutic surgical staging improves survival as compared with chemoradiation based on PET/CT in women with stages IB2-IVA cervical cancer.

    Background Nodal staging with sentinel node biopsy (SLNB), post-lumpectomy radiotherapy (RT), and endocrine therapy (ET) for estrogen receptor-positive (ER+) tumors is valuable in the treatment of early-stage (stages 1 or 2) breast cancer but used less often for elderly women. Methods This retrospective study investigated women referred for surgical evaluation of biopsy-proven primary early-stage invasive breast cancer from January 2001 to December 2010. Clinicopathologic features, treatment course, and outcomes for women ages 80–89 years and 50–59 years were compared. Results The study identified 178 eligible women ages 80–89 years and 169 women ages 50–59 years. The elderly women more often had grade 1 or 2 disease (p = 0.003) and ER+ tumors (p = 0.007) and less frequently had undergone adjuvant therapies (all p ≤ 0.001). Lumpectomy was performed more commonly for the elderly (92 vs. 83 %, p = 0.02), and axillary surgery was less commonly performed (46 vs. 96 %; p < 0.001). Fewer elderly women had undergone post-lumpectomy RT (42 vs. 89 %; p < 0.001) and ET for ER+ tumors (72 vs. 95 %; p < 0.001). During the median follow-up period of 56 months for the 80- to 89-year old group and 98 months for the 50- to 59-year-old group, death from breast cancer was similar (4 vs. 5 %; p = 0.5). The two groups respectively experienced 7 versus 6 locoregional recurrences and 11 versus 13 distant recurrences. Conclusions The octogenarians had disease survivorship similar to that of the younger women despite less frequent use of adjuvant therapies, likely reflecting lower-risk disease features. Whether increased use of axillary surgery, post-lumpectomy RT, and/or ET for ER+ tumors would further improve outcomes is an important area for further study, but treatment should not be deferred solely on the basis of age.

    Full Text Available UNLABELLED: Cell cycle protein expression plays an important role in the pathophysiology of cervical cancer. However, few studies have attempted to correlate the use of these biomarkers with the clinical progression of the tumor. OBJECTIVES: 1 To analyze the expression of Ki-67, p53 and p16(INK4a in cervical cancer, 2 to correlate the relative expression of these proteins as well as clinical parameters with the stage of disease, and 3 to determine the HPV DNA prevalence and subtype distribution. METHODS: Tissue Micro-Arrays (TMA from patients with invasive cervical cancer (ICC and controls were analyzed. HPV DNA detection was done by PCR and in situ hybridization. Ki-67, p53 and p16(INK4a were analyzed by immunohistochemistry; clinical data was derived from the chart review. RESULTS: Advanced tumor stage (III and IV was strongly associated (p55 years old, with more than four pregnancies and with the lack of formal education. HPV DNA was found in 94.3% of cases with the most prevalent types being HPV16 (67.5%, followed by HPV33 (12.0% and HPV35 (3.6%. High expression of Ki-67 and p16 was more common in the advanced FIGO stages (p = 0.023. Women with HPV16 tended to be younger (50.9 years; SE 1.9 compared to women with other types (59.9 years; SE 2.8. CONCLUSION: We found that Ki-67 and p16 expression were independently associated with the tumor stage. We also noted that about 1/3 of the cervical cancers in this Brazilian cohort were not associated with HPV types directly targeted by the current HPV vaccines.

    To evaluate the treatment results in early stage non-small cell lung cancer patients who have undergone fiducial-less CyberKnife radiosurgery (CKRS). From June 2011 to November 2013, 58 patients underwent CKRS at Asan Medical Center for stage I lung cancer. After excluding 14 patients, we retrospectively reviewed the records of the remaining 44 patients. All analyses were performed using SPSS ver. 21. The median age at diagnosis was 75 years. Most patients had inoperable primary lung cancer with a poor pulmonary function test with comorbidity or old age. The clinical stage was IA in 30 patients (68.2%), IB in 14 (31.8%). The mean tumor size was 2.6 cm (range, 1.2 to 4.8 cm), and the tumor was smaller than 2 cm in 12 patients (27.3%). The radiation dose given was 48-60 Gy in 3-4 fractions. In a median follow-up of 23.1 months, local recurrence occurred in three patients (2-year local recurrence-free survival rate, 90.4%) and distant metastasis occurred in 13 patients. All patients tolerated the radiosurgery well, only two patients developing grade 3 dyspnea. The most common complications were radiation-induced fibrosis and pneumonitis. Eight patients died due to cancer progression. The results showed that fiducial-less CKRS shows comparable local tumor control and survival rates to those of LINAC-based SABR or CKRS with a fiducial marker. Thus, fiducial-less CKRS using Xsight lung tracking system can be effectively and safely performed for patients with medically inoperable stage I non-small cell lung cancer without any risk of procedure-related complication.

    Objective: To evaluate the clinical significance of clinical staging and magnetic resonance imaging (MRI) staging for prostate cancer before radical prostatectomy. Methods: Thirty-two patients with organ confined prostate cancer were reviewed to assess the accuracy of clinical staging and MRI staging to correlate with pathological staging results after radical prostatectomy. Results: 33.3% (10/30) prostate cancer patients with staging C and 3.3% (1/30) prostate cancer patients with staging D were diagnosed by pathology after radical prostatectomy in 30 patients with prostate cancer with clinical staging B, and 36.7% (11/30) under staging; Only one patient was over staging in clinical staging C. 19.1% (4/21) prostate cancer patients with staging C were diagnosed in 21 patients with prostate cancer and under staging with MRI staging B; 11.1% (1/9) was over staging with MRI staging C. The clinical staging and MRI staging had more correlation with pathological staging results (P=0.002), and PPV of the organ confined prostate cancer by clinical staging and MRI staging were 63.3% and 80.9% respectively, and NPV of nonorgan confined prostate cancer by clinical staging and MRI staging were 50% and 88.9% respectively. MRI staging was more specificity and accuracy than that of clinical staging to predict pathological staging results before radical prostatectomy (P=0.023). Conclusion: The MRI staging was more accuracy than that of clinical staging to predict pathological staging results in organ confined and nonorgan confined prostate cancer before radical prostatectomy.

    OBJECTIVE To evaluate the feasibility of 18F-deoxyglucose positron emission tomography (18F-FDG PET) in the staging of non-small cell lung cancer(NSCLC).METHODS 105 patients with NSCLC had been examined by 18F-FDG PET before radiotherapy. The results of the 18F-FDG PET examination were compared with those of CT:RESULTS The staging was changed in 38 patients because of 18F-FDG PET findings, with PET resulting in upstaging in 31 patients and downstaging in seven patients. Because of distant metastasis detected by PET, 21 patients received palliative treatment. Six of the seven downstaged patients underwent radical surgery, among which the PET findings were concordant with the pathological findings in five patients. Distant metastasis detected by PET elevated the pre-PET stage: at stage 110.0% (2/20), stage Ⅱ 14.3% (3/21 ) and stage Ⅲ 25.0% (16/64), respectively.CONCLUSION 18F-FDG PET, by changing clinical staging in 36.2% (38/105)of NSCLC patients, has an impact on treatment strategy in NSCLC patients.

  4. Clinical comparison of magnetic resonance imaging and computed tomography in preoperative staging of primary lung cancer

    Energy Technology Data Exchange (ETDEWEB)

    Akata, Soichi (Tokyo Medical Coll. (Japan))

    1989-11-01

    To determine the value of magnetic resonance imaging (MRI) for the preoperative staging in primary lung cancer, the findings of MRI were compared with those of computed tomography (CT) in 71 consecutive patients with adenocarcinoma (5), squamous cell carcinoma (20), large cell carcinoma (5), small cell carcinoma (3), or cystadenocarcinoma (2). There was no difference between MRI and CT in diagnosing T factors. However, MRI tended to overestimate the diagnosis of N factors and CT tended to underestimate it for adenocarcinoma, although there was no difference between the imaging modalities for squamous cell carcinoma. In diagnosing metastatic mediastinal lymph nodes of squamous cell carcinoma, MRI was comparable in sensitivity to CT. However, the sensitivity of MRI was 10% higher than that of CT for hilar lymph nodes of squamous cell carcinoma and mediastinal and hilar lymph nodes of adenocarcinoma. Accuracy of MRI was equal to that of CT. Calcified lymph nodes were misinterpreted as enlarged lymph nodes on MRI. MRI is difficult to perform in patients with arrhythmia and respiratory disturbance because of longer imaging time. It may, however, become a promising tool for qualitative diagnosis of metastatic cancer. (N.K.).

  5. Natural History of Clinically Staged Low- and Intermediate-Risk Prostate Cancer Treated With Monotherapeutic Permanent Interstitial Brachytherapy

    International Nuclear Information System (INIS)

    Purpose: To evaluate the natural history of clinically staged low- and intermediate-risk prostate cancer treated with permanent interstitial seed implants as monotherapy. Methods and Materials: Between April 1995 and May 2005, 463 patients with clinically localized prostate cancer underwent brachytherapy as the sole definitive treatment. Men who received supplemental external beam radiotherapy or androgen deprivation therapy were excluded. Dosimetric implant quality was determined based on the minimum dose that covered 90% of the target volume and the volume of the prostate gland receiving 100% of the prescribed dose. Multiple parameters were evaluated as predictors of treatment outcomes. Results: The 12-year biochemical progression-free survival (bPFS), cause-specific survival, and overall survival rates for the entire cohort were 97.1%, 99.7%, and 75.4%, respectively. Only pretreatment prostate-specific antigen level, percent positive biopsy cores, and minimum dose that covered 90% of the target volume were significant predictors of biochemical recurrence. The bPFS, cause-specific survival, and overall survival rates were 97.4%, 99.6%, and 76.2%, respectively, for low-risk patients and 96.4%, 100%, and 74.0%, respectively, for intermediate-risk patients. The bPFS rate was 98.8% for low-risk patients with high-quality implants versus 92.1% for those with less adequate implants (p < 0.01), and it was 98.3% for intermediate-risk patients with high-quality implants versus 86.4% for those with less adequate implants (p < 0.01). Conclusions: High-quality brachytherapy implants as monotherapy can provide excellent outcomes for men with clinically staged low- and intermediate-risk prostate cancer. For these men, a high-quality implant can achieve results comparable to high-quality surgery in the most favorable pathologically staged patient subgroups.

  8. Bone radioisotope scanning: usefulness in the evaluation and observation of patients with breast cancer in clinical stage II, III, IV

    International Nuclear Information System (INIS)

    The clinical records of 420 patients with diagnosis of breast cancer well documented by the pathological anatomy in clinical stage II, III and IV were reviewed. In each one of them has been done at least a bone scanning during the diagnosis. In 52 cases carried out sericeous dosages of CA 15-3 and in some cases it was necessary to administer Samarium-153 EDTMP as palliative therapy of bone pain. The presence of secondary gamma-graphic focuses was 0/84 cases (0%) in clinical stage II, 54/265 cases (20%) in III and 41/91 cases (45%) in IV. The one focus appeared in 6.7% of the cases. In 7 of the 52 cases that received sericeous dosages of CA 15-3 were detected secondary osseous lesions, and 5 of them presented a marker elevation. The bone scanning has shown in many cases the presence of getters focuses in singular places of skeleton, urinary excretory system or mammary tissue. The gamma rays from Sm-153 allowed us to get some appropriate basal views post-therapy of the secondary lesions. The results show that the great incidence of secondary lesions in the skeleton occurred in cases of stages III and IV unlike other countries. The serial repetition of the radioisotope scanning. The presence of one focus in the skeleton of a patient with a well-known neoplasia makes us to do a careful evaluation of the focus nature. The presence of tracer accumulation in the kidney, ureter and bladder allows us to infer the pathology of excretory system that is the first evidence of its presence in many cases.

    BACKGROUND: The Barcelona Clinic Liver Cancer (BCLC) staging system for hepatocellular carcinoma (HCC) recommends transarterial chemoembolization (TACE) as the ifrst line therapy for stage B patients and sorafenib treatment for stage C patients. However, stage C patients exhibit variations in terms of tumor burden, liver function, and extrahepatic metastasis, which could potentially affect disease outcome. Here, we assessed whether the Cancer of the Liver Italian Program (CLIP) scores can help identify stage C patients likely to beneift from TACE. METHODS: Out of 295 BCLC stage C HCC patients enrolled between January 2009 and December 2011, those with platelet counts >30×109 cells/L, total bilirubin RESULTS: The median overall survival (OS) was 6 months [95% conifdence interval (CI): 4.64-7.36]. The OS was 9 months for the TACE group and 4 months for the BSC group. The TACE group had a longer OS than the BSC subgroup for CLIP scores 0-2 [13 months (95% CI: 8.55-17.45) vs 4 months (95% CI:0.00-10.96),P=0.001]. No signiifcant differences were found be-tween the TACE and BSC groups for CLIP scores 3-5. The CLIP score and treatment methods were found to be independent prognostic factors. CONCLUSIONS: BCLC stage C HCC patients exhibit deifnite disease heterogeneity and can be reclassiifed by using the CLIP scoring system. Moreover, patients with CLIP scores 0-2 are likely to beneift from TACE. However, additional studies with long-term follow-up will be required to validate these ifndings.

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical outcome and cosmetic results in early stage breast cancer patients treated with conservative surgery plus radiation therapy. Methods: From May 1995 to December 2002, 109 such patients were so treated. The post-operative radiotherapy consisted of whole-breast 6 MV linear accelerator irradiation with two tangential half-fields to a total dose of 45-52 Gy (mean 48.6 Gy), followed by a boost irradiation to the tumor bed. Among them, 79 patients received 10-12 Gy (DB) boost by interstitial implantation brachytherapy (192Ir HDR, Nucletron), with single plane implantation for T1 and double plane implantation for T2 tumor. Thirty patients received 15 Gy boost by electron beam. Adjuvant/concurrent chemotherapy (CMF or CEF) and hormonotherapy were also used according to the patients' clinical characteristics. The cosmetic results were scored by both the doctor and the patients. Results: The overall actuarial 5-year survival was 93.8%, with local recurrence of 6.5%. No radiation-induced ulcer was observed in the breast except for acute inflammation at skin pinholes in 5 patients treated by interstitial implant brachytherapy. Among the 75 patients who had had breast examination, cosmetic result scored as good by patient and doctor were 81% and 87%, respectively. The good rate assessed by doctor in brachytherapy boost group and electron beam boost group were 81.2% (39/48) and 85.2% (23/27), There was no significant difference between these two boost techniques (P>0.05). Conclusions: Tumor bed boost irradiation by either brachytherapy or electron beam technique can provide satisfactory local control in early breast cancer treated with conservative surgery plus radiotherapy without increasing the side effects. There is no significant difference in cosmetic result between these two boost techniques. (authors)

    Objective To evaluate the clinical impact of body diffusion weighted imaging (DWI) on the diagnosis and preoperative N staging of cervical cancer. Methods Twenty-four patients (mean age 37.9 years old) with proved cervical cancer by cervical biopsy and 24 female patients with other suspected pelvic abnormalities received preoperative body DWI scan. Results of body DWI were compared with pathological findings. The apparent diffusion coefficient (ADC) values of normal cervix and different pathological types of cervical cancer were compared. ADC value of normal or inflammatory lymph nodes was also compared with that of metastatic ones. Student's t test was used for statistical analysis. Results There were 5 adenocarcinomas and 19 epitheliomas showed with biopsy results, and DWI showed 21 cervical lesions out of them (87.5%). ADC values of the normal cervix (n = 24), epithelioma (n = 19), and adenocar-cinoma (n = 5)were (1.73 ± 0.31) ×10-3, (0.88 ± 0.22)×1O-3, and (1.08 ± 0.12)×10-3 mm2/s, respectively. Statistical analysis showed significant difference in ADC value between normal cervical tissue and either tumor tissues (both P < 0.01). In patients had lymphadenectomy (n = 24), totally 67 lymph nodes including 16 metastatic lymph nodes were pathologically analyzed, and DWI showed 66 (98.5%) out of them. ADC values of normal/inflammatory and metastatic lymph nodes were (1.07 ± 0.16) ×10-3 and (0.77 ± 0.13)×10-3 mm2/s (P < 0.01). Receiver operating characteristic (ROC) curve of ADC value of metastatic lymph node showed that area under curve was 0.961. Conclusions ADC value in cervical carcinoma is lower than that in normal cervix, and ADC may have predictive value in subtype discrimination. ADC value may improve the preoperative characterization of lymph node metastasis. And at least abdominal and pelvic DWI scan is suggested for N staging evaluation in such patients.

    Full Text Available Hepatocellular carcinoma (HCCis the fifth most common malignancy associated with high mortality. One of the risk factors for HCC is chronic hepatitis B virus (HBV infection. The treatment strategy for the disease is dependent on the stage of HCC, and the Barcelona clinic liver cancer (BCLC staging system is used in most HCC cases. However, the molecular characteristics of HBV-related HCC in different BCLC stages are still unknown. Using GSE14520 microarray data from HBV-related HCC cases with BCLC stages from 0 (very early stage to C (advanced stage in the gene expression omnibus (GEO database, differentially expressed genes (DEGs, including common DEGs and unique DEGs in different BCLC stages, were identified. These DEGs were located on different chromosomes. The molecular functions and biology pathways of DEGs were identified by gene ontology (GO analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG pathway analysis, and the interactome networks of DEGs were constructed using the NetVenn online tool. The results revealed that both common DEGs and stage-specific DEGs were associated with various molecular functions and were involved in special biological pathways. In addition, several hub genes were found in the interactome networks of DEGs. The identified DEGs and hub genes promote our understanding of the molecular mechanisms underlying the development of HBV-related HCC through the different BCLC stages, and might be used as staging biomarkers or molecular targets for the treatment of HCC with HBV infection.

    Objective The purpose of this study was to evaluate the prognosis according to the number of high risk factors in patients with high risk factors after radical hysterectomy and adjuvant chemoradiation therapy for early stage cervical cancer. Methods Clinicopathological variables and clinical outcomes of patients with FIGO (International Federation of Gynecology and Obstetrics) stage IB1 to IIA cervical cancer who had one or more high risk factors after radical hysterectomy and adjuvant chemoradiation therapy were retrospectively analyzed. Patients were divided into two groups according to the number of high risk factors (group 1, single high risk factor; group 2, two or more high risk factors). Results A total of 93 patients were enrolled in the present study. Forty nine out of 93 (52.7%) patients had a single high risk factor, and 44 (47.3%) had two or more high risk factors. Statistically significant differences in stage and stromal invasion were observed between group 1 and group 2. However, age, histology, tumor size, and lymphovascular space invasion did not differ significantly between the groups. Distant recurrence occurred more frequently in group 2, and the probability of recurrence and death was higher in group 2. Conclusion Patients with two or more high risk factors had worse prognosis in early stage cervical cancer. For these patients, consideration of new strategies to improve survival may be worthwhile. Conduct of further clinical trials is warranted for development of adjuvant treatment strategies individualized to each risk group. PMID:27200308

  15. B3GNT3 Expression Is a Novel Marker Correlated with Pelvic Lymph Node Metastasis and Poor Clinical Outcome in Early-Stage Cervical Cancer.

    Full Text Available The β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3 encodes a member of the B3GNT family that functions as the backbone structure of dimeric sialyl-Lewis A and is involved in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. B3GNT3 has been implicated as an important element in the development of certain cancers. However, the characteristics of B3GNT3 in the development and progression of cancer remain largely unknown. Thus, our study aimed to investigate the expression pattern and the prognostic value of B3GNT3 in patients with early-stage cervical cancer.The mRNA and protein levels of B3GNT3 expression were examined in eight cervical cancer cell lines and ten paired cervical cancer tumors, using real-time PCR and western blotting, respectively. Immunohistochemistry (IHC was used to analyze B3GNT3 protein expression in paraffin-embedded tissues from 196 early-stage cervical cancer patients. Statistical analyses were applied to evaluate the association between B3GNT3 expression scores and clinical parameters, as well as patient survival.B3GNT3 expression was significantly upregulated in cervical cancer cell lines and lesions compared with normal cells and adjacent noncancerous cervical tissues. In the 196 cases of tested early-stage cervical cancer samples, the B3GNT3 protein level was positively correlated with high risk TYPES of human papillomavirus (HPV infection (P = 0.026, FIGO stage (P < 0.001, tumor size (P = 0.025, tumor recurrence (P = 0.004, vital status (P < 0.001, concurrent chemotherapy and radiotherapy (P = 0.016, lymphovascular space involvement (P = 0.003 and most importantly, lymph node metastasis (P = 0.003. Patients with high B3GNT3 expression had a shorter overall survival (OS and disease-free survival (DFS compared with those with low expression of this protein. Multivariate analysis suggested that B3GNT3 expression is an independent prognostic indicator for cervical cancer patients.Our study

    In the National Comprehensive Cancer Network (NCCN) guidelines, oxaliplatin (L-OHP)-based chemotherapeutic regimens, including 5-fluorouracil, Leucovorin (LV), and L-OHP (FOLFOX); capecitabine and L-OHP (CapeOX); and 5-fluorouracil, folinic acid, and L-OHP (FLOX) are designated as category 1 recommendations for postoperative adjuvant chemotherapy in Stage III colon cancer, followed by capecitabine and 5-fluorouracil plus LV as category 2A recommendations. We studied the selection of drugs for adjuvant chemotherapy and assessed the tolerability and safety of CapeOX and tegafur-uracil (UFT) plus LV (UFT/LV) in patients with Stage III colon cancer. The study group included 104 consecutive patients with Stage III colon cancer who underwent curative surgery. One patient changed hospitals immediately after surgery. Among the remaining 103 patients, 82 (80%) received adjuvant chemotherapy and 21 (20%) did not. CapeOX was administered to 32 patients (31%), UFT/LV to 49 patients (48%), and capecitabine to 1 patient (1%). In 59 patients, the treatment choice was determined according to the patient's preference; 32 patients (54%) selected CapeOX, 26 (44%) selected UFT/LV, and 1 (2%) selected no chemotherapy. The treatment completion rate was 80% for CapeOX and 84% for UFT/LV. Among patients who completed chemotherapy, dose reduction and drug withdrawal were not required in 22% of patients who received CapeOX and 80% of those who received UFT/LV. Neither CapeOX nor UFT/LV was associated with any serious adverse events. The tolerability and safety of CapeOX and UFT/LV were acceptable. However, CapeOX dose had to be carefully adjusted according to each patient's condition.

    The aim of the study was to evaluate the impact of MammaPrint on treatment decision-making in patients with breast cancer. Clinicopathologic information of all breast cancer patients referred for MammaPrint testing in South Africa was collected from 2007 until 2014. A total of 107 patients (109 tumors) with estrogen receptor/progesterone receptor positive and human epidermal growth factor receptor-2 negative tumors were selected with tumors ≥10 mm, or when 1-3 nodes were involved without extra-nodal extension. None of the clinical indicators correlated significantly with the MammaPrint risk classification, which changed the decision for adjuvant chemotherapy in 52% of patients. Of 60 patients who were clinically high risk, 62% had a low-risk MammaPrint result and of the 47 clinically low -risk patients 40% had a high-risk MammaPrint result. This study indicates that MammaPrint could reduce the need for adjuvant chemotherapy by 17% using the selection criteria stipulated. The significant impact on treatment decisions confirmed the clinical utility of MammaPrint independent of standard clinicopathologic risk factors as supported by long-term clinical outcome studies.

  1. Scalpel or SABR for Treatment of Early-Stage Lung Cancer: Clinical Considerations for the Multidisciplinary Team

    International Nuclear Information System (INIS)

    Treatment options for early-stage (T1-2 N0) non-small cell lung cancer are often limited by the patient's advanced age, poor performance status, and comorbidities. Despite these challenges, stereotactic ablative radiotherapy (SABR) provides a highly effective and safe therapy for intrathoracic tumors and has become the standard of care for delivering definitive treatment in medically inoperable patients. High-quality treatment, which includes reliable immobilization, accurate tumor targeting, and precise verification of dose delivery, is essential both to achieve successful cure and to avoid debilitating toxicities. Generally, SABR is well tolerated in patients with peripherally located tumors, but even centrally or superiorly located lesions can be treated if there is adequate conformal avoidance of normal structures and/or modified fractionation to meet dose constraints. While several preliminary studies suggest that SABR is as efficacious as surgery in operable patients, results of randomized data will illuminate whether the indications for SABR can be expanded to include patients who are candidates for surgical resection. Herein, we review the rationale for using SABR and its application in treating different patient populations with early-stage lung cancer

    Full Text Available Background and objective The efficacy of complete resection of the cancer for patients with stage IIIa non-small cell lung cancer (NSCLC is limited. Synthetic therapy is taken the lead in advocating at present. However, the value of post-operative radiotherapy is not still clear. The aim of this study is to evaluate the survival time and side effects of postoperative chemotherapy or chemoradiotherapy in the treatment of stage IIIa NSCLC. Methods Between December 2003 and June 2007, 52 cases that have completed followed-up data with stage IIIa of NSCLC received in the First Affiliated Hospital of Dalian Medical University. Twenty-three patients received postoperative chemoradiotherapy (group A and 29 patients received postoperative chemotherapy combined with radiotherapy (group B. Group A adopted platinum-based combination chemotherapy for 4-6 cycles. The chemotherapeutics included gemcitabine, vinorelbine and docetaxel. Group B used chemotherapy for 2-4 cycles and then received 3-dimensional conformal radiotherapy (3D-CRT. The prescribe dose of target volume was 50 Gy. The chemotherapy was same as for group A and needed 4 cycles in all. The impact of postoperative adjuvant treatment on survival and toxicity was observed in patients with stage IIIa NSCLC and the reason of disease progression was analyzed. Results The median survival was 32.5 months in group A and 31.9 months in group B (P=0.371. Progression-free survival extended about 6 months (P=0.044. The survival rate was 87% at 1 year, 0.1% at 2 year, 33% at 3 year for group A compared with 93%, 69%, 45% for group B. The major side effects were hematological and gastrointestinal toxicities, including nausea, vomiting and neutropenia. There was no significant difference in these toxicities between the two groups (P>0.05. Radioactiv esophageal infection occurred in 17.2% of the patients.

    Objective: The aim of our study was to analyze the clinical results and prognosis for early elderly patients after surgery and to explore the rational treatment. Methods: Between January 1992 and December 2008, 98 early elderly breast cancer patients aged ≥ 65 years were treated with surgery, of which 52 patients received modified radical mastectomy and 46 patients received simple mastectomy. Results: Sixty-four (65.3%) patients had comorbidities including coronary heart disease, hypertension, diabetes, etc. After a median follow up of 56 months (21 to 280 months), the 5-year cumulative survival rate of breast modified radical mastectomy group and mastectomy group were 84.0% and 82.7%, separately (P = 0.653). The 5-year recurrence rate were 3.8% and 8.1%, separately (P = 0.504). Conclusion: The simple mastectomy is suitable for the treatment of early elderly breast cancer patients for its lower complication and recurrence rate. Early old women with breast cancer may be safely treated by simple mastectomy. Our findings suggest that modified radical mastectomy does not significantly increase the overall survival.

    Liver cancer is a malignancy of the digestive system and has a high morbidity and mortality rate. Local intervention has become a viable option in identifying liver treatment. The aim of the present study was to analyze the clinical effects of treating liver cancer in middle and advanced stages using ultrasound-guided percutaneous ethanol injection (PEI) in tumors combined with radiofrequency ablation (RFA). A total of 100 patients with stage III–IV liver cancers were selected to participate in the study. Patients were divided into groups. In group A, treatment was initiated with PEI and after 1–2 weeks RFA was applied while in group B treatment was initiated with RFA and after 1–2 weeks PEI was applied. Patients in group C received PEI and RFA simultaneously. The clinical effects in the 3 groups were compared after 6-month follow ups. The volume of tumor ablation necrosis in group A was significantly greater than that in the groups B and C, while the size was significantly smaller compared to groups B and C after ablation. For group A, the complete ablation rate was significantly higher than that in groups B and C, and the differences were statistically significant (P<0.05). Liver damage indices, including raising levels of glutamic-pyruvic transaminase and total bilirubin, were significantly decreased in group A (P<0.05). The survival rate in group A was also significantly higher than in groups B and C (P<0.05). In conclusion, for patients with liver cancer in middle and advanced stages, the treatment method using PEI followed by RFA was more beneficial in terms of improving the tumor ablation rate, alleviating liver damages and increasing survival rates.

    Purpose We evaluated the usefulness of the in vitro adenosine triphosphate-based chemotherapy response assay (ATP-CRA) for prediction of clinical response to fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer. Materials and Methods Tumor specimens of 86 patients with pathologically confirmed stage II colorectal adenocarcinoma were tested for chemosensitivity to fluorouracil. Chemosensitivity was determined by cell death rate (CDR) of drug-exposed cells, calculated by comparing the intracellular ATP level with that of untreated controls. Results Among the 86 enrolled patients who underwent radical surgery followed by fluorouracil-based adjuvant chemotherapy, recurrence was found in 11 patients (12.7%). The CDR ≥ 20% group was associated with better disease-free survival than the CDR < 20% group (89.4% vs. 70.1%, p=0.027). Multivariate analysis showed that CDR < 20% and T4 stage were poor prognostic factors for disease-free survival after fluorouracil-based adjuvant chemotherapy. Conclusion In stage II colorectal cancer, the in vitro ATP-CRA may be useful in identifying patients likely to benefit from fluorouracil-based adjuvant chemotherapy. PMID:26511802

  8. Prognostic value of response to external radiation in stage IIIB cancer cervix in predicting clinical outcomes: A retrospective analysis of 556 patients from India

    International Nuclear Information System (INIS)

    Background and purpose: To evaluate the prognostic significance of response to external beam radiation (EBRT) in predicting the clinical outcomes in stage IIIB cancer cervix and to find out factors affecting response to EBRT. Patients and methods: This retrospective study included 556 patients of cancer cervix stage IIIB treated between 1996 and 2001 with EBRT (46 Gy/23fx/4.5 weeks) followed by intracavitary radiotherapy (ICRT). At the end of EBRT, response to EBRT was grouped as 'no gross residual tumor'(NRT) or 'gross residual tumor'(GRT). Results: Follow up ranged from 2 to 93 months with a median of 36 months. Median dose to point A was 81 Gy. At the end of EBRT, 393 patients (70.7%) attained NRT response. NRT responders had significantly better 5 year pelvic control, disease free survival (DFS) and overall survival (OS) than those who had a GRT response (75.6 vs. 54.6%; 60.6 vs. 31.9% and 62.6 vs. 33.7%, respectively; all P values <0.0001). Apart from response to EBRT, overall treatment time also has emerged as an independent factor to affect all clinical outcomes in multivariate analysis but age had significant impact on pelvic control only. Age was the only factor, which significantly influenced the response to EBRT in univariate as well as multivariate analysis (P=<0.001, OR=1.973, 95% C.I. 1.357-2.868). Patients with age more than 50 years had more NRT response (77%) than patients with age less than 50 years (63.8%). Conclusions: Patients who attain NRT response to EBRT will have an impressive long term pelvic control, DFS and OS in stage IIIB cancer cervix. Older patients (≥50 years) attain significantly higher NRT rates than younger patients

    Full Text Available Introduction: Ovarian cancer is the leading cause of death from gynecological cancer. Non-specific symptoms early in disease and the lack of specific biomarkers hinder early diagnosis. Multi-marker blood screening tests have shown promise for improving identification of early stage disease; however, available tests lack sensitivity, and specificity. Materials and Methods: In this study, pooled deeply-depleted plasma from women with Stage 1, 2 or 3 ovarian cancer and healthy controls were used to compare the 2-dimensional gel electrophoresis (2-DE protein profiles and identify potential novel markers of ovarian cancer progression. Results/Discussion: Stage-specific variation in biomarker expression was observed. For example, apolipoprotein A1 expression is relatively low in control and Stage 1, but shows a substantial increase in Stage 2 and 3, thus, potential of utility for disease confirmation rather than early detection. A better marker for early stage disease was tropomyosin 4 (TPM4. The expression of TPM4 increased by 2-fold in Stage 2 before returning to "normal" levels in Stage 3 disease. Multiple isoforms were also identified for some proteins and in some cases, displayed stage-specific expression. An interesting example was fibrinogen alpha, for which 8 isoforms were identified. Four displayed a moderate increase at Stage 1 and a substantial increase for Stages 2 and 3 while the other 4 showed only moderate increases. Conclusion: Herein is provided an improved summary of blood protein profiles for women with ovarian cancer stratified by stage.

  12. Effectiveness of surgery and individualized high-dose hyperfractionated accelerated radiotherapy on survival in clinical stage I non-small cell lung cancer. A propensity score matched analysis

    International Nuclear Information System (INIS)

    Background and purpose: Surgery is considered the treatment of choice for early-stage non-small cell lung cancer (NSCLC). Patients with poor pulmonary function or other comorbidities are treated with radiotherapy. The objective of this investigation is to compare the 3-year survival of two early-stage NSCLC populations treated in two different hospitals, either by surgical resection (lobectomy) or by individualized high-dose accelerated radiotherapy, after matching patients by propensity scoring analysis. Methods: A retrospective comparative study has been performed on two series of consecutive patients with cytohistological diagnosis of NSCLC, clinically staged IA by means of PET-scan (radiotherapy group) and pathologically staged IA (surgery group). Results: A total of 157 cases were initially selected for the analysis (110 operated and 47 treated by radiotherapy). Patients in the radiotherapy group were older, with higher comorbidity and lower FEV1% with 3-years probability of survival for operated patients higher than that found for patients treated by radiotherapy. After matching by propensity scoring (using age and FEV1%), differences disappear and 3-years probability of survival had no statistical differences. Conclusions: Although this is a non-randomized retrospective analysis, we have not found 3-years survival differences after matching cases between surgery and radiotherapy. Nevertheless, data presented here support the continuous investigation for non-surgical alternatives in this disease.

    Prostate cancer represents an increasing health burden.The past 20 years,with the introduction of prostate-specific antigen (PSA),has seen prostate cancer move increasingly from a condition that presented with locally advanced disease or metastases to one that is found upon screening.More is also known about the pathology of pre-malignant lesions.Diagnosis relies on trans-rectal ultrasound (TRUS) to obtain biopsies from throughout the prostate,but TRUS is not useful for staging.Imaging for staging,such as magnetic resonance imaging or computed tomography,still has a low accuracy compared with pathological specimens.Current techniques are also inaccurate in identifying lymph node and bony metastases.Nomograms have been developed from the PSA,Gleason score and clinical grading to help quantify the risk of extra-capsular extension in radical prostatectomy specimens.Improved clinical staging modalities are required for more reliable prediction of pathological stage and for monitoring of response to treatments.

    Purpose: To prospectively examine quality of life (QOL) of patients with early stage breast cancer treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy. Methods and Materials: Between March 2004 and December 2008, 151 patients with early stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients included those with Tis-T2 tumors measuring ≤3 cm excised with negative surgical margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. QOL was measured using European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, version 3.0, and QLQ-BR23 questionnaires. The QLQ-C30 and QLQ-BR23 questionnaires were evaluated during pretreatment and then at 6 to 8 weeks, 3 to 4 months, 6 to 8 months, and 1 and 2 years after treatment. Results: The median follow-up was 55 months. Breast symptom scores remained stable in the months after treatment, and they significantly improved 6 to 8 months after treatment. Scores for emotional functioning, social functioning, and future perspective showed significant improvement 2 years after treatment. Symptomatic fat necrosis was associated with several changes in QOL, including increased pain, breast symptoms, systemic treatment side effects, dyspnea, and fatigue, as well as decreased role functioning, emotional functioning, and social functioning. Conclusions: HDR multicatheter interstitial brachytherapy was well tolerated, with no significant detrimental effect on measured QOL scales/items through 2 years of follow-up. Compared to pretreatment scores, there was improvement in breast symptoms, emotional functioning, social functioning, and future perspective 2 years after treatment.

    Purpose: To prospectively evaluate cosmetic outcomes in women treated with accelerated partial breast irradiation using high-dose-rate interstitial brachytherapy for early-stage breast cancer. Methods and Materials: Between 2004 and 2008, 151 patients with early-stage breast cancer were enrolled in a phase 2 prospective clinical trial. Eligible patients had stage Tis-T2 tumors of ≤3 cm that were excised with negative margins and with no nodal involvement. Patients received 3.4 Gy twice daily to a total dose of 34 Gy. Both the patients and the treating radiation oncologist qualitatively rated cosmesis as excellent, good, fair, or poor over time and ascribed a cause for changes in cosmesis. Cosmetic outcome was evaluated quantitatively by percentage of breast retraction assessment (pBRA). Patients also reported their satisfaction with treatment over time. Results: Median follow-up was 55 months. The rates of excellent-to-good cosmesis reported by patients and the treating radiation oncologist were 92% and 97% pretreatment, 91% and 97% at 3 to 4 months' follow-up, 87% and 94% at 2 years, and 92% and 94% at 3 years, respectively. Breast infection and adjuvant chemotherapy were independent predictors of a fair-to-poor cosmetic outcome at 3 years. Compared to pretreatment pBRA (7.35), there was no significant change in pBRA over time. The volume receiving more than 150 Gy (V150) was the only significant predictor of pBRA. The majority of patients (86.6%) were completely satisfied with their treatment. Conclusions: Patients and the treating physician reported a high rate of excellent-to-good cosmetic outcomes at all follow-up time points. Acute breast infection and chemotherapy were associated with worse cosmetic outcomes. Multicatheter interstitial brachytherapy does not significantly change breast size as measured by pBRA.

    Purpose: The aim of the study was to improve computed tomography (CT)-based high-risk clinical target volume (HR CTV) delineation protocols for cervix cancer patients, in settings without any access to magnetic resonance imaging (MRI) at the time of brachytherapy. Therefore the value of a systematic integration of comprehensive three-dimensional (3D) documentation of repetitive gynecological examination for CT-based HR CTV delineation protocols, in addition to information from FIGO staging, was investigated. In addition to a comparison between reference MRI contours and two different CT-based contouring methods (using complementary information from FIGO staging with or without additional 3D clinical drawings), the use of standardized uterine heights was also investigated. Material and methods: Thirty-five cervix cancer patients with CT- and MR-images and 3D clinical drawings at time of diagnosis and brachytherapy were included. HR CTV{sub stage} was based on CT information and FIGO stage. HR CTV{sub stage} {sub +3Dclin} was contoured on CT using FIGO stage and 3D clinical drawing. Standardized HR CTV heights were: 1/1, 2/3 and 1/2 of uterine height. MRI-based HR CTV was delineated independently. Resulting widths, thicknesses, heights, and volumes of HR CTV{sub stage}, HR CTV{sub stage+3Dclin} and MRI-based HR CTV contours were compared. Results: The overall normalized volume ratios (mean{+-}SD of CT/MRI{sub ref} volume) of HR CTV{sub stage} and HR{sub stage+3Dclin} were 2.6 ({+-}0.6) and 2.1 ({+-}0.4) for 1/1 and 2.3 ({+-}0.5) and 1.8 ({+-}0.4), for 2/3, and 1.9 ({+-}0.5) and 1.5 ({+-}0.3), for 1/2 of uterine height. The mean normalized widths were 1.5{+-}0.2 and 1.2{+-}0.2 for HR CTV{sub stage} and HR CTV{sub stage+3Dclin}, respectively (p < 0.05). The mean normalized heights for HR CTV{sub stage} and HR CTV{sub stage+3Dclin} were both 1.7{+-}0.4 for 1/1 (p < 0.05.), 1.3{+-}0.3 for 2/3 (p < 0.05) and 1.1{+-}0.3 for 1/2 of uterine height. Conclusion: CT-based HR

  5. Systemic review of the patterns of failure following stereotactic body radiation therapy in early-stage non-small-cell lung cancer: Clinical implications

    International Nuclear Information System (INIS)

    Purpose: To analyze the patterns of failure, the toxicity profile, and the factors influencing efficacy of stereotactic body radiation (SBRT) for early-stage non-small-cell lung cancer (NSCLC). Methods and materials: A search was based on PubMed electronic databases. All searches were conducted in May, 2009. Results: The local control ranged from 80% to 100% in most studies with adequate isocentric or peripheral biologically effective dose (BED). Recurrences were associated with increased tumor size. The main pattern of failure after SBRT was distant metastasis. Grades 3-5 toxicity occurred mostly in centrally located tumors, and adjuvant chemotherapy may further decrease all recurrences; possibly translating to a survival benefit in large or centrally located tumors where high BED cannot be safely reached. Conclusion: SBRT is an excellent treatment option for early-stage, and mostly medically inoperable, NSCLC. BED at both the isocenter and the tumor periphery is very important for optimal tumor control; higher doses are required for large (≥T2) lesions; SBRT for centrally located tumors can be feasible with a much less aggressive dose regimen than 60-66 Gy/3 fractions and adjacent critical structures excluded from the target volume; chemotherapy may optimize the clinical outcome in large or centrally located lesions.

  6. Accrual to Cancer Clinical Trials

    Accrual to cancer clinical trials (CCT) is imperative to safeguard continued improvement in cancer outcomes. A retrospective chart review was performed of patients (n=140) starting a new anti-cancer agent in a north Dublin cancer centre. This review was performed over a four-month period, beginning in November 2015. Only 29% (n=41) had a CCT option. The overall accrual rate to CCT was 5% (n=7), which is comparable to internationally reported figures. The main reasons for failure to recruit to CCT included the lack of a CCT option for cancer type (n=30, 23%), stage (n=25, 19%), and line of treatment (n=23, 17%). Over the last decade, the rate of accrual to CCTs has in fact doubled and the number of trials open to recruitment has tripled. Ongoing governmental and philanthropic support is necessary to continue this trend to further expand CCT patient options with a target accrual rate of 10%.

  7. Acute Toxicity Profile and Compliance to Accelerated Radiotherapy Plus Carbogen and Nicotinamide for Clinical Stage T2–4 Laryngeal Cancer: Results of a Phase III Randomized Trial

    International Nuclear Information System (INIS)

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2–4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2–4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2–4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

    Cervical cancer is the worldwide leading cause of cancer-related death of women, especially in developing countries. The International Federation of Gynecology and Obstetrics recommends staging during surgery, however, surgical-pathologic staging would not be feasible in cases of more advanced cancers. Generally, in these cases, the staging is performed by means of clinical and gynecological examination and basic imaging studies. However, such an approach fails to demonstrate the actual extent of the disease, and does not include significant prognostic factors such as tumor volume, stromal invasion and lymph node involvement. Magnetic resonance imaging has increasingly been utilized in cervical cancer staging, since at early stages of the disease its performance may be compared to intraoperative findings and, at advanced stages, it shows to be superior to the clinical evaluation. Additionally, magnetic resonance imaging presents an excellent imaging resolution for the different densities of pelvic structures, does not require ionizing radiation, is comfortable for the patient, improves de staging, allowing the early detection of recurrence and the identification of reliable prognostic factors which contribute to the therapeutic decision making process and results prediction with an excellent cost-effectiveness. The present article is aimed at reviewing the most significant aspects of magnetic resonance imaging in the cervical cancer staging. (author)

    It is a matter of controversy whether prophylactic lymph node dissection improves prognosis and survival in papillary thyroid carcinoma (PTC) patients without suspicion of lymph node metastases either clinically or on ultrasonography. It is possible that in such patients the use of lymphatic mapping and sentinel lymph node (SLN) biopsy, as are employed for other tumours, will be of assistance. The aim of this study was to evaluate the feasibility of preoperative {sup 99m}Tc-nanocolloid lymphoscintigraphy and an intra-operative SLN procedure in the management of PTC patients. Twenty-five consecutive patients were entered in the study between April 2005 and October 2005. All had a preoperative diagnosis of malignancy obtained by fine-needle aspiration cytology (FNAC), without clinical or ultrasonographic evidence of loco-regional lymph node involvement. Patients underwent preoperative lymphoscintigraphy after the injection of {sup 99m}Tc-nanocolloid [median 6 MBq (range 4-9 MBq) in 0.1-0.2 ml saline injected intratumorally under ultrasound guidance] and an intra-operative SLN procedure using a hand-held gamma probe. Surgery was performed by the same surgeon in all patients. Preoperative lymphoscintigraphy identified at least one SLN in all patients. During surgery, using the gamma probe, the surgeon was able to find at least one SLN in all cases. A good correlation was found between preoperative imaging and probe results. Metastasis was found in at least one SLN in 12 (48%) patients. In seven (28%) patients the involved SLN was the most radioactive SLN, while in five (20%) patients a less radioactive SLN was involved by malignancy. Ten of these 12 patients had only micrometastases (<2 mm). Micrometastases were found in the most radioactive SLN in six cases and in less radioactive SLNs in four cases, while in two patients more lymph nodes visualised at lymphoscintigraphy ipsilateral to the primary tumour were sites of metastasis. The rate of nodal involvement was very

    Open clinical trial data offer many opportunities for the scientific community to independently verify published results, evaluate new hypotheses and conduct meta-analyses. These data provide a springboard for scientific advances in precision medicine but the question arises as to how representative clinical trials data are of cancer patients overall. Here we present the integrative analysis of data from several cancer clinical trials and compare these to patient-level data from The Cancer Genome Atlas (TCGA). Comparison of cancer type-specific survival rates reveals that these are overall lower in trial subjects. This effect, at least to some extent, can be explained by the more advanced stages of cancer of trial subjects. This analysis also reveals that for stage IV cancer, colorectal cancer patients have a better chance of survival than breast cancer patients. On the other hand, for all other stages, breast cancer patients have better survival than colorectal cancer patients. Comparison of survival in different stages of disease between the two datasets reveals that subjects with stage IV cancer from the trials dataset have a lower chance of survival than matching stage IV subjects from TCGA. One likely explanation for this observation is that stage IV trial subjects have lower survival rates since their cancer is less likely to respond to treatment. To conclude, we present here a newly available clinical trials dataset which allowed for the integration of patient-level data from many cancer clinical trials. Our comprehensive analysis reveals that cancer-related clinical trials are not representative of general cancer patient populations, mostly due to their focus on the more advanced stages of the disease. These and other limitations of clinical trials data should, perhaps, be taken into consideration in medical research and in the field of precision medicine. PMID:26776196

    To assess the additional functional vascular information and the relationship between perfusion measurements and glucose metabolism (SUVmax) obtained by including a perfusion CT study in a whole-body contrast-enhanced PET/CT protocol in primary lung cancer lesions. Enrolled in this prospective study were 34 consecutive patients with a biopsy-proven diagnosis of lung cancer who were referred for contrast-enhanced PET/CT staging. This prospective study was approved by our institutional review board, and informed consent was obtained from all patients. Perfusion CT was performed with the following parameters: 80 kV, 200 mAs, 30 scans during intravenous injection of 50 ml contrast agent, flow rate 5 ml/s. Another bolus of contrast medium (3.5 ml/s, 80 ml, 60-s delay) was administered to ensure a full diagnostic contrast-enhanced CT scan for clinical staging. The perfusion CT data were used to calculate a range of tumour vascularity parameters (blood flow, blood volume and mean transit time), and tumour FDG uptake (SUVmax) was used as a metabolic indicator. Quantitative and functional parameters were compared and in relation to location, histology and tumour size. The nonparametric Kruskal-Wallis rank sum test was used for statistical analysis. A cut-off value of 3 cm was used according to the TNM classification to discriminate between T1 and T2 tumours (i.e. T1b vs. T2a). There were significant perfusion differences (lower blood volumes and higher mean transit time) between tumours with diameter >30 mm and tumours with diameter <30 mm (p < 0.05; blood volume 5.6 vs. 7.1 ml/100 g, mean transit time 8.6 vs. 3.9 s, respectively). Also there was a trend for blood flow to be lower in larger lesions (p < 0.053; blood flow 153.1 vs. 98.3 ml/100 g tissue/min). Significant inverse correlations (linear regression) were found between blood volume and SUVmax in tumours with diameter >30 mm in diameter. Perfusion CT combined with PET/CT is feasible technique that may provide

    Nodal staging is important in prostate cancer treatment. While surgical lymph node dissection is the classic method of determining whether lymph nodes harbor malignancy, this is a very invasive technique. Current noninvasive approaches to identifying malignant lymph nodes are limited. Conventional imaging methods rely on size and morphology of lymph nodes and have notoriously low sensitivity for detecting malignant nodes. New imaging techniques such as targeted positron emission tomography (PET) imaging and magnetic resonance lymphography (MRL) with iron oxide particles are promising for nodal staging of prostate cancer. In this review, the strengths and limitations of imaging techniques for lymph node staging of prostate cancer are discussed.

    Full Text Available Lung cancers account for the majority of brain metastases which pose major therapeutic challenges. Biomarkers prognosticating for the development of brain metastases in patients with non-small cell lung cancers (NSCLC may improve personalized care. Six serum proteomic biomarkers were previously investigated at Memorial Sloan Kettering but their associations with brain metastases were unknown.Serum NSE, CYFRA 21-1, ProGRP, SCC-Ag, TIMP1, and HE4 by ELISA-based proteomic assays were prospectively collected from consecutive patients with stage IV NSCLC. Pre-treatment serum biomarker levels as well as age, histology, and epidermal growth factor receptor (EGFR mutation status were evaluated for association with the baseline presence of brain metastases using logistic regression and multivariable analysis. For patients without brain metastases at baseline, the cumulative incidence of subsequent brain metastases were compared according to baseline biomarkers and clinical factors using Gray's test.A total of 118 patients were enrolled, 31 (26%; 95% CI 0.19-0.35 had brain metastases at baseline and a further 26 (22%; 95% CI 0.15-0.30 developed brain metastases subsequently. Pre-treatment serum biomarker levels were available in 104 patients. There was no significant association between the six serum biomarkers and the baseline presence or subsequent development of brain metastases. Age younger than 65 years was the only clinical factor significantly associated with brain metastasis at baseline (OR 3.00; 95% CI 1.22-7.34, P = 0.02 by multivariable analysis. A trend toward increased cumulative incidence of subsequent brain metastases was observed in patients with EGFR mutation (p = 0.2, but this was not statistically significant possibly due to small sample size.Serum NSE, CYFRA 21-1, Pro-GRP, SCC-Ag, TIMP1, and HE4 are not significantly associated with brain metastases. Our methods taking into account follow-up time may be applied to independent datasets

    Objective: To estimate the impact of parametrial infiltration and lymph node metastasis on clinical outcome in women with early-stage cervical cancer following radical hysterectomy and pelvic lymphadenectomy. Methods: Clinical re-cords and pathologic slides of 532 patients with early-stage cervical cancer (330 Ib and 202 Ila) treated with radical hyster-ectomy and pelvic lymphadenectomy were reviewed. The study group comprised 520 patients with squamous cell carcinoma and 12 patients with adenocarcinoma of the cervix. Median follow-up time was 67 months. The association among the various histopathologic predictors of outcome was determined with analysis. The influence of the predictors on outcome was exam-ined with log rank survival methods and the Cox regression model. Results: FIGO stage, histologic type, tumor size, depth of invasion, parametrial infiltration, lymph node metastasis, and remote metastasis were identified as significantly biologically relevant and therefore were included as candidate predictors in multivariate analysis. In particular, parametrial infiltration and lymph node metastasis were found to be simultaneous predictors of death on multivariate analysis (P < 0.05). After controlling for these two factors, the other variables considered were not statistically significant up to a two-way interaction. Conclusion: Presence of parametrial infiltration and/or lymph node metastasis in women with early-stage cervical cancer is an indepen-dent poor prognostic factor. In addition, the relatively poor survival of women with more than one lymph nodes identified with cancer cells.

  9. Hypofractionated High-Dose Proton Beam Therapy for Stage I Non-Small-Cell Lung Cancer: Preliminary Results of A Phase I/II Clinical Study

    International Nuclear Information System (INIS)

    Purpose: To present treatment outcomes of hypofractionated high-dose proton beam therapy for Stage I non-small-cell lung cancer (NSCLC). Methods and Materials: Twenty-one patients with Stage I NSCLC (11 with Stage IA and 10 with Stage IB) underwent hypofractionated high-dose proton beam therapy. At the time of irradiation, patient age ranged from 51 to 85 years (median, 74 years). Nine patients were medically inoperable because of comorbidities, and 12 patients refused surgical resection. Histology was squamous cell carcinoma in 6 patients, adenocarcinoma in 14, and large cell carcinoma in 1. Tumor size ranged from 10 to 42 mm (median, 25 mm) in maximum diameter. Three and 18 patients received proton beam irradiation with total doses of 50 Gy and 60 Gy in 10 fractions, respectively, to primary tumor sites. Results: Of 21 patients, 2 died of cancer and 2 died of pneumonia at a median follow-up period of 25 months. The 2-year overall and cause-specific survival rates were 74% and 86%, respectively. All but one of the irradiated tumors were controlled during the follow-up period. Five patients showed recurrences 6-29 months after treatment, including local progression and new lung lesions outside of the irradiated volume in 1 and 4 patients, respectively. The local progression-free and disease-free rates were 95% and 79% at 2 years, respectively. No therapy-related toxicity of Grade ≥3 was observed. Conclusions: Hypofractionated high-dose proton beam therapy seems feasible and effective for Stage I NSCLC. Proton beams may contribute to enhanced efficacy and lower toxicity in the treatment of patients with Stage I NSCLC

    Full Text Available Abstract Background Stereotactic ablative radiotherapy (SABR can achieve excellent local control rates in early-stage non-small cell lung cancer (NSCLC and has emerged as a standard treatment option for patients who cannot undergo surgery or those with isolated recurrences. However, factors that may predict toxicity or survival are largely unknown. We sought here to identify predictors of survival and pneumonitis after SABR for NSCLC in a relatively large single-institution series. Methods Subjects were 130 patients with stage I NSCLC treated with four-dimensional computed tomography (4D CT –planned, on-board volumetric image–guided SABR to 50 Gy in 4 fractions. Disease was staged by positron emission tomography/computed tomography (PET/CT and scans were obtained again at the second follow-up after SABR. Results At a median follow-up time of 26 months, the 2-year local control rate was 98.5%. The median overall survival (OS time was 60 months, and OS rates were 93.0% at 1 year, 78.2% at 2 years, and 65.3% at 3 years. No patient experienced grade 4–5 toxicity; 15 had radiation pneumonitis (12 [9.3%] grade 2 and 3 [2.3%] grade 3. Performance status, standardized uptake value (SUVmax on staging PET/CT, tumor histology, and disease operability were associated with OS on univariate analysis, but only staging SUVmax was independently predictive on multivariate analysis (P = 0.034. Dosimetric factors were associated with radiation pneumonitis on univariate analysis, but only mean ipsilateral lung dose ≥9.14 Gy was significant on multivariate analysis (P = 0.005. Conclusions OS and radiation pneumonitis after SABR for stage I NSCLC can be predicted by staging PET SUVmax and ipsilateral mean lung dose, respectively.

    Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification. PMID:27491237

    Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging.

    Prostate cancer is the most common malignancy of men in Germany. Transrectal ultrasound (TRUS) is the primary used imaging modality. Patients with elevated PSA levels undergo systematic TRUS-guided transrectal biopsy of the prostate for histologic confirmation of prostate cancer. Magnetic resonance imaging (MRI) using the combined endorectal body phased-array coil may be indicated in men with one or more negative prostate biopsies. The detection of prostate cancer by conventional MRI can be improved by an additional dynamic contrast-enhanced MR study and proton MR spectroscopy. Local staging of prostate cancer by MRI is more accurate compared with digital rectal examination and transrectal ultrasound. However, accuracies reported in the literature for these procedures vary widely. Bone scintigraphy with 99mTc-bisphosphonate is currently the method of choice for the detection of bone metastases. However, more recent techniques such as whole-body MRI and PET using 18F-FDG, 11C-choline or 11C-acetate as tracers were found to have higher sensitivities. (orig.)

    To design clear guidelines for the staging and follow-up of patients with ovarian cancer, and to provide the radiologist with a framework for use in multidisciplinary conferences. Guidelines for ovarian cancer staging and follow-up were defined by the female imaging subcommittee of the ESUR (European Society of Urogenital Radiology) based on the expert consensus of imaging protocols of 12 leading institutions and a critical review of the literature. Computed tomography (CT) with coverage of the base of the lungs to the inguinal region is regarded as the imaging technique of choice for preoperative staging. Critical diagnostic criteria are presented and the basis for a structured report for preoperative staging is outlined. Following primary treatment for ovarian cancer, clinical assessment and CA-125 are routinely used to monitor patients. For suspected recurrence, CT remains the imaging modality of choice, with positron emission tomography (PET)/CT emerging as the optimal imaging technique for suspected recurrence, particularly in patients with negative CT or magnetic resonance imaging (MRI). CT is the imaging modality of choice for preoperative staging and detection of recurrence in patients with ovarian cancer. (orig.)

    This review presents the current state of the art regarding multiparametric magnetic resonance (MR) imaging of prostate cancer. Technical requirements and clinical indications for the use of multiparametric MR imaging in detection, localization, characterization, staging, biopsy guidance, and active surveillance of prostate cancer are discussed. Although reported accuracies of the separate and combined multiparametric MR imaging techniques vary for diverse clinical prostate cancer indications, multiparametric MR imaging of the prostate has shown promising results and may be of additional value in prostate cancer localization and local staging. Consensus on which technical approaches (field strengths, sequences, use of an endorectal coil) and combination of multiparametric MR imaging techniques should be used for specific clinical indications remains a challenge. Because guidelines are currently lacking, suggestions for a general minimal protocol for multiparametric MR imaging of the prostate based on the literature and the authors' experience are presented. Computer programs that allow evaluation of the various components of a multiparametric MR imaging examination in one view should be developed. In this way, an integrated interpretation of anatomic and functional MR imaging techniques in a multiparametric MR imaging examination is possible. Education and experience of specialist radiologists are essential for correct interpretation of multiparametric prostate MR imaging findings. Supportive techniques, such as computer-aided diagnosis are needed to obtain a fast, cost-effective, easy, and more reproducible prostate cancer diagnosis out of more and more complex multiparametric MR imaging data.

    Objective: To comparatively study dosimetric evaluation, side effects in early and late stage, and cosmetic outcome between MammoSite and interstitial using high-dose-rate (HDR) brachytherapy accelerated partial breast irradiation (APBI) in early stage breast cancer patient after conserving surgery. Methods: From January 2004 to December 2004, 10 breast cancer cases were treated with HDR 192Ir APBI after Lumpectomy surgery, 6 cases with interstitial brachytherapy, 4 cases with MammoSite. Sources were placed during the operation in all patients, distance from cavity to skin > 5-7 mm in interstitial brachytherapy group, one case is 6.5 mm, 3 cases > 10 mm in MammoSite group. Treatment Target area is 20 mm away from cavity in interstitial brachytherapy group with DHI 0.77, 10 mm away from Balloon margin in MammoSite with DHI 0.73. Results: Follow up 12-24 months while median follow-up was 18 months for the whole group (100%). During the treatment, grade III acute reactions were not seen in both group, grade I or II were seen including: erythema, edema, tenderness and infection. More late toxicity reaction including skin fibrosis, breast tenderness and fat necrosis were observed in interstitial brachytherapy group than that of MammoSite group. Cosmetic outcome evaluation were excellent in 12 months 100% (patient) and 83% (doctor) in interstitial brachytherapy, 100% in MammoSite group, respectively, none recurrence. Conclusions: Interstitial brachytherapy shows more uniformity in dose distribution as well as larger treatment volume, while MammoSite tends to be stable in repeatability and easy in use. Both groups show excellent cosmetic results, with same acute and late reactions. (authors)

    Purpose: To investigate pulmonary function test (PFT) results and arterial blood gas changes (complete PFT) following stereotactic body radiation therapy (SBRT) and to see whether baseline PFT correlates with lung toxicity and overall survival in medically inoperable patients receiving SBRT for early stage, peripheral, non-small cell lung cancer (NSCLC). Methods and Materials: During the 2-year follow-up, PFT data were collected for patients with T1-T2N0M0 peripheral NSCLC who received effectively 18 Gy × 3 in a phase 2 North American multicenter study (Radiation Therapy Oncology Group [RTOG] protocol 0236). Pulmonary toxicity was graded by using the RTOG SBRT pulmonary toxicity scale. Paired Wilcoxon signed rank test, logistic regression model, and Kaplan-Meier method were used for statistical analysis. Results: At 2 years, mean percentage predicted forced expiratory volume in the first second and diffusing capacity for carbon monoxide declines were 5.8% and 6.3%, respectively, with minimal changes in arterial blood gases and no significant decline in oxygen saturation. Baseline PFT was not predictive of any pulmonary toxicity following SBRT. Whole-lung V5 (the percentage of normal lung tissue receiving 5 Gy), V10, V20, and mean dose to the whole lung were almost identical between patients who developed pneumonitis and patients who were pneumonitis-free. Poor baseline PFT did not predict decreased overall survival. Patients with poor baseline PFT as the reason for medical inoperability had higher median and overall survival rates than patients with normal baseline PFT values but with cardiac morbidity. Conclusions: Poor baseline PFT did not appear to predict pulmonary toxicity or decreased overall survival after SBRT in this medically inoperable population. Poor baseline PFT alone should not be used to exclude patients with early stage lung cancer from treatment with SBRT.

    Objective: To assess the efficacy and toxicity of the combination of paclitaxel plus carboplatin as neoadjuvant chemotherapy (NACT) for locally advanced cervical cancer (LACC) prior to radical hysterectomy and pelvic lymphadenectomy. Methods: We reviewed patients with cervical cancer of the International Federation of Gynecology and Obstetrics (FIGO) stage IB2-IIB who underwent neoadjuvant chemotherapy (NACT) with paclitaxel plus carboplatin followed by radical hysterectomy (NACT group) or only received primary radical surgery (PRS group) in our hospital between Jan 2007 and Jan 2012. Toxicity, NACT response, surgery pathological factors and survival data were collected and analyzed. Results: In the NACT group, the overall response rate was 71.3% (82/115). Eighteen (15.7%) patients achieved complete remission. Well differentiated tumors showed a more favorable response to NACT (P=0.011). Myelosuppression was the most common adverse effect (51.7%) and serious adverse effects were rare (3.4%). The median follow-up period was 44 months (range, 6-75). The NACT responders had significantly longer OS and PFS when compared to the non-NACT responders and patients in the PRS group. Conclusion: Patients with LACC can benefit from neoadjuvant chemotherapy with paclitaxel plus carboplatin when they have response to the chemotherapeutic agents. PMID:26550314

    Background We compared video‐assisted thoracoscopic surgery (VATS) lobectomy and stereotactic body radiation therapy (SABR) to explore clinical outcomes in the treatment of patients with early stage NSCLC. Methods Major medical databases were systematically searched to identify studies on VATS and SBRT published between January 2010 and October 2015. English publications of stage I and II NSCLC with adequate patients and SBRT doses were included. A multivariate random effects model was used to perform meta‐analysis to compare overall survival (OS) and disease‐free survival (DFS) between VATS and SBRT, adjusting for median age and operable patient numbers. Results Thirteen VATS (3436 patients) and 24 SBRT (4433) studies were eligible. The median age and follow‐up duration was 68 years and 42 months for VATS and 74 years and 29.4 months for SBRT patients. After adjusting for the proportion of operable patients and median age, the estimated OS rates at one, two, three, and five years with VATS were 94%, 89%, 84%, and 69% compared with 96%, 94%, 89%, and 82% for SBRT. The estimated DFS rates at one, two, three, and five years with VATS were 97%, 93%, 87%, and 77% compared with 86%, 80%, 73%, and 58% for SBRT. Conclusion Before adjustment, patients treated with SBRT had poorer clinical outcomes compared to those treated with VATS. A substantial difference between median age and operability exists between patients treated with SBRT and VATS. After adjusting for these differences, OS and DFS did not differ significantly between the two techniques. PMID:27385987

However, ALND remains standard management of the axilla when a tumor-positive sentinel lymph node is identified.Methods: We identified 460 patients with breast cancer (clinically T1/T2N0M0 from the database for 1999–2004. Patient age ranged from 26 to 81 (median 50 years. Patients who underwent mastectomy or breast-conserving surgery with or without ALND were compared for regional recurrence, disease-free survival, and overall survival.Results: Patients with ALND (n = 308 were compared with the no ALND group (n = 152. Five-year overall survival and disease-free survival were not significantly different between the two groups, while there was a significant difference between them for regional recurrence. Of the 152 patients who did not undergo axillary dissection, four developed ipsilateral axillary disease, most of whom were rescued by delayed axillary dissection. Further, the criterion for identifying lymphedema was used, ie, a 2 cm circumferential change at any measured location. As a result, the incidence of lymphedema in the ALND group was 12.7%, while it was not seen in the non ALND group.Conclusion: There is a possibility that ALND may be omitted for cT1/T2N0M0 breast cancer through a combination of hormone therapy and adjuvant chemotherapy.Keywords: breast cancer, axillary lymph node dissection

    A literature review was undertaken to investigate whether transrectal ultrasound can predict the local stage of prostate cancer. Twelve papers were found which correlated ultrasound findings with surgical findings and another paper reported on strategic staging biopsies guided by transrectal...... ultrasound. Eleven of these papers reported on ultrasound findings in patients in whom digital rectal examination had defined localized disease. One paper compared ultrasound findings and digital rectal findings. One paper indicated that transrectal ultrasound, though not suited to patients with clinically...... localized disease defined by digital rectal examination, may be superior as the initial staging tool. We conclude that transrectal ultrasound has too low a specificity to upgrade the diagnostic results of digital rectal examination, but that it may be more useful as the primary staging tool and for guidance...

  10. Cost-effectiveness of a 21-gene recurrence score assay versus Canadian clinical practice in women with early-stage estrogen- or progesterone-receptor-positive, axillary lymph-node negative breast cancer

    International Nuclear Information System (INIS)

    A 21-gene recurrence score (RS) assay may inform adjuvant systematic treatment decisions in women with early stage breast cancer. We sought to investigate the cost effectiveness of using the RS-assay versus current clinical practice (CCP) in women with early-stage estrogen- or progesterone-receptor-positive, axilliary lymph-node negative breast cancer (ER+/ PR + LN- ESBC) from the perspective of the Canadian public healthcare system. We developed a Markov model to project the lifetime clinical and economic consequences of ESBC. We evaluated adjuvant therapy separately in post- and pre-menopausal women with ER+/ PR + LN- ESBC. We assumed that the RS-assay would reclassify pre- and post-menopausal women among risk levels (low, intermediate and high) and guide adjuvant systematic treatment decisions. The model was parameterized using 7 year follow up data from the Manitoba Cancer Registry, cost data from Manitoba administrative databases, and secondary sources. Costs are presented in 2010 CAD. Future costs and benefits were discounted at 5%. The RS-assay compared to CCP generated cost-savings in pre-menopausal women and had an ICER of $60,000 per QALY gained in post-menopausal women. The cost effectiveness was most sensitive to the proportion of women classified as intermediate risk by the RS-assay who receive adjuvant chemotherapy and the risk of relapse in the RS-assay model. The RS-assay is likely to be cost effective in the Canadian healthcare system and should be considered for adoption in women with ER+/ PR + LN- ESBC. However, ongoing assessment and validation of the assay in real-world clinical practice is warranted

  16. Patterns of Local-Regional Failure in Completely Resected Stage IIIA(N2) Non-Small Cell Lung Cancer Cases: Implications for Postoperative Radiation Therapy Clinical Target Volume Design

    International Nuclear Information System (INIS)

    Purpose: To analyze patterns of local-regional failure (LRF) for completely resected stage IIIA(N2) non-small cell lung cancer (NSCLC) patients treated in our hospital and to propose a clinical target volume (CTV) for postoperative radiation therapy (PORT) in these patients. Methods and Materials: From 2005 to 2011, consecutive patients with pT1-3N2 NSCLC who underwent complete resection in our hospital but who did not receive PORT were identified. The patterns of first LRF were assessed and evaluated as to whether these areas would be encompassed by our proposed PORT CTV. Results: With a median follow-up of 24 months, 173 of 250 patients (69.2%) experienced disease recurrence. Of the 54 patients with LRF as the first event, 48 (89%) had recurrence within the proposed PORT CTV, and 6 (11%) had failures occurring both within and outside the proposed CTV (all of which occurred in patients with right-lung cancer). Ninety-three percent of failure sites (104 of 112) would have been contained within the proposed PORT CTV. For left-sided lung cancer, the most common lymph node station failure site was 4R, followed by 7, 4L, 6, 10L, and 5. For right-sided lung cancer, the most common site was station 2R, followed by 10R, 4R, and 7. Conclusions: LRF following complete surgery was an important and potentially preventable pattern of failure in stage IIIA(N2) patients. Ipsilateral superior mediastinal recurrences dominated for right-sided tumors, whereas left-sided tumors frequently involved the bilateral superior mediastinum. Most of the LRF sites would have been covered by the proposed PORT CTV. A prospective investigation of patterns of failure after PORT (following our proposed CTV delineation guideline) is presently underway and will be reported in a separate analysis

    Full Text Available Microarrays have been used for more than two decades in preclinical research. The tumor transcriptional profiles were analyzed to select cancer-associated genes for in-deep functional characterization, to stratify tumor subgroups according to the histopathology or diverse clinical courses, and to assess biological and cellular functions behind these gene sets. In lung cancer—the main type of cancer causing mortality worldwide—biomarker research focuses on different objectives: the early diagnosis of curable tumor diseases, the stratification of patients with prognostic unfavorable operable tumors to assess the need for further therapy regimens, or the selection of patients for the most efficient therapies at early and late stages. In non-small cell lung cancer, gene and miRNA signatures are valuable to differentiate between the two main subtypes’ squamous and non-squamous tumors, a discrimination which has further implications for therapeutic schemes. Further subclassification within adenocarcinoma and squamous cell carcinoma has been done to correlate histopathological phenotype with disease outcome. Those tumor subgroups were assigned by diverse transcriptional patterns including potential biomarkers and therapy targets for future diagnostic and clinical applications. In lung cancer, none of these signatures have entered clinical routine for testing so far. In this review, the status quo of lung cancer gene signatures in preclinical and clinical research will be presented in the context of future clinical perspectives.

    Full Text Available Objective. The aim of this study was to document the survival advantage of lowering stage at detection from Stage IIIC to Stage IIIA epithelial ovarian cancer. Methods. Treatment outcomes and survival were evaluated in patients with Stage IIIA and Stage IIIC epithelial ovarian cancer treated from 2000 to 2009 at the University of Kentucky Markey Cancer Center (UKMCC and SEER institutions. Results. Cytoreduction to no visible disease (P<0.0001 and complete response to platinum-based chemotherapy (P<0.025 occurred more frequently in Stage IIIA than in Stage IIIC cases. Time to progression was shorter in patients with Stage IIIC ovarian cancer (17±1 months than in those with Stage II1A disease (36±8 months. Five-year overall survival (OS improved from 41% in Stage IIIC patients to 60% in Stage IIIA patients treated at UKMCC and from 37% to 56% in patients treated at SEER institutions for a survival advantage of 19% in both data sets. 53% of Stage IIIA and 14% of Stage IIIC patients had NED at last followup. Conclusions. Decreasing stage at detection from Stage IIIC to stage IIIA epithelial ovarian cancer is associated with a 5-year survival advantage of nearly 20% in patients treated by surgical tumor cytoreduction and platinum-based chemotherapy.

    In the present chapter the authors present a brief overview of the diagnostic methods proposed over time for Hodgkin lymphoma (HL) spread detection, moving from surgical procedures, through standard radiological and functional imaging techniques to the present state of the art for HL staging. The main body of the review will be dedicated to the recently published guidelines for lymphoma staging (including HL) agreed by the experts during the 12th International Congress for Malignant Lymphoma in Lugano. The recommendations of the panel on how to integrate flurodeoxyglucose positron emission tomography (FDG-PET) scan in the armamentarium of staging procedures will be presented and commented, with a special emphasis on the utility of special procedures, such as bone marrow trephine biopsy, which is deemed no longer needed in the PET era. While the HL diagnosis is straightforward in most cases, sometimes HL is a subtle disease, difficult to diagnose for the paucity of symptoms, the absence of physical findings, or for concomitant immunologic disorders: a compete overview of the common and rare patterns of HL clinical presentation will be also offered. The future perspective of PET scan use will be based on a operator-independent, quantitative readings of the scan thanks to a plethora of sophisticated dedicated software, which are now available, able to quantify every voxel captured by the tumor to display the metabolically active tumor volume. Moreover, new tracers are now available able to track the new pathways of cellular metabolism beside glycolysis such as amino acids or purine-analogues or specific oncoproteins; the preliminary, promising results will be reported. Preliminary results from other imaging techniques, such as diffusion-weighted magnetic resonance (DW-MRI) will be also reported. PMID:27496305

  1. Evolving molecularly targeted therapies for advanced-stage thyroid cancers.

    Bible, Keith C; Ryder, Mabel

    2016-07-01

    Increased understanding of disease-specific molecular targets of therapy has led to the regulatory approval of two drugs (vandetanib and cabozantinib) for the treatment of medullary thyroid cancer (MTC), and two agents (sorafenib and lenvatinib) for the treatment of radioactive- iodine refractory differentiated thyroid cancer (DTC) in both the USA and in the EU. The effects of these and other therapies on overall survival and quality of life among patients with thyroid cancer, however, remain to be more-clearly defined. When applied early in the disease course, intensive multimodality therapy seems to improve the survival outcomes of patients with anaplastic thyroid cancer (ATC), but salvage therapies for ATC are of uncertain benefit. Additional innovative, rationally designed therapeutic strategies are under active development both for patients with DTC and for patients with ATC, with multiple phase II and phase III randomized clinical trials currently ongoing. Continued effort is being made to identify further signalling pathways with potential therapeutic relevance in thyroid cancers, as well as to elaborate on the complex interactions between signalling pathways, with the intention of translating these discoveries into effective and personalized therapies. Herein, we summarize the progress made in molecular medicine for advanced-stage thyroid cancers of different histotypes, analyse how these developments have altered - and might further refine - patient care, and identify open questions for future research.

    The treatment of uterine cervical carcinoma is largely dependent on the tumor stage. Despite significant inaccuracies in the clinical examination, uterine cervical cancer remains the only gynecological form of cancer still largely staged according to clinical findings. Although imaging is still not included in the staging the recently published revised FIGO (Federation International de Gynecologie et d'Obstetrique) system encourages the use of modern cross-sectional imaging (magnetic resonance imaging MRI and computed tomography CT). Due to its high soft tissue contrast MRI allows excellent non-invasive assessment of the cervix with direct tumor delineation as well as assessment of the prognosis based on morphological factors. Studies in the literature report an accuracy of 93% for MRI in the preoperative assessment of tumor size and in the differentiation of operable from advanced cervical cancer. Therefore MRI is considered to be the optimal modality for diagnostic evaluation starting from FIGO stage IB1, for radiation therapy planning, and for exclusion of recurrence in follow-up. In this paper we give an overview of the role of magnetic resonance imaging in preoperative staging of uterine cervical cancer. (orig.) [German] Die Therapieplanung beim Zervixkarzinom ist weitgehend von der Stadieneinteilung nach FIGO (Federation International de Gynecologie et d'Obstetrique) abhaengig, die trotz erheblicher Ungenauigkeiten bei der klinischen Stadieneinteilung weiterhin aufgrund klinischer Untersuchungsbefunde erfolgt. Obwohl bildgebende Verfahren nach wie vor fuer die Stadieneinteilung nicht vorgesehen sind, wird im kuerzlich erschienen revidierten Stagingsystem der FIGO zum ersten Mal die Verwendung moderner Schnittbilddiagnostik (MRT und CT) befuerwortet. Die MRT ermoeglicht dank ihres hohen Weichteilkontrasts ein ausgezeichnetes nichtinvasives Staging des Zervixkarzinoms mit direkter Tumordarstellung sowie einer Prognoseabschaetzung anhand

  7. MR staging accuracy for endometrial cancer based on the new FIGO stage

    International Nuclear Information System (INIS)

    Background: Magnetic resonance imaging (MRI) has been frequently used to determine a preoperative treatment plan for gynecologic cancers. However, the MR accuracy for staging an endometrial cancer is not satisfactory based on the old FIGO staging system. Purpose: To evaluate MR accuracy for staging endometrial cancer using the new FIGO staging system. Material and Methods: Between January 2005 and May 2009, 199 women underwent surgery due to endometrial cancer. In each patient, an endometrial cancer was staged using MR findings based on the old FIGO staging system and then repeated according to the new FIGO staging system for comparison. Histopathologic findings were used as a standard of reference. Results: The accuracy of MRI in the staging of endometrial carcinoma stage I, II, III, and IV using the old FIGO staging system were 80% (159/199), 89% (178/199), 90% (179/199), and 99% (198/199), respectively, compared to 87% (174/199), 97% (193/199), 90% (179/199), and 99% (198/199), respectively, when using the new FIGO staging criteria. The overall MR accuracy of the old and new staging systems were 51% (101/199) and 81% (161/199), respectively. Conclusion: MRI has become a more useful tool in the preoperative staging of endometrial cancers using the new FIGO staging system compared to the old one with increased accuracy

  10. Distribution pattern of lymph node metastases and its implication in individualized radiotherapeutic clinical target volume delineation of regional lymph nodes in patients with stage IA to IIA cervical cancer

    International Nuclear Information System (INIS)

    To study the distribution pattern of lymph node metastases of stage IA to IIA cervical cancer and to clarify the individualized clinical target volume delineation of regional lymph nodes (CTVn). A total of 665 cases with International Federation Gynecology and Obstetrics stage IA to IIA cervical cancer who underwent radical hysterectomy and pelvic lymphadenectomy were retrospectively reviewed. The clinicopathological factors related to lymph node metastases were analyzed using logistic regression analysis. Pelvic lymph node metastases were found in 168 of 665 patients resulting in a metastasis rate of 25.3%. Binary logistic regression analysis showed that age, lymph vascular space involvement, and deep stromal invasion statistically influenced pelvic lymph node metastases (p = 0.017, < 0.001, < 0.001, respectively). Pathological morphology type, lymph node metastases of the obturator, the external iliac and internal iliac, and the para-aortic had a strong influence on lymph node metastases of the common iliac (p = 0.022, 0.003, < 0.001, 0.009, respectively). Tumor size and lymph node metastases of the common iliac were significantly related to lymph node metastases of the para-aortic (p = 0.045, < 0.001, respectively). Lymph node metastases of the obturator, the external iliac and internal iliac were strongly correlated to lymph node metastases of the circumflex iliac node distal to the external iliac node (CINDEIN; p = 0.027, 0.024, respectively). Factors related to lymph node metastases should be comprehensively considered to design and tailor CTVn for radiotherapy of cervical cancer. Selective regional irradiation including the correlated lymphatic drainage regions should be performed

  15. Current trends in staging rectal cancer

    2011-01-01

    Management of rectal cancer has evolved over the years.In this condition preoperative investigations assist in deciding the optimal treatment.The relation of the tumor edge to the circumferential margin (CRM) is an important factor in deciding the need for neoadjuvant treatment and determines the prognosis.Those with threatened or involved margins are offered long course chemoradiation to enable R0 surgical resection.Endoanal ultrasound (EUS) is useful for tumor (T) staging;hence EUS is a useful imaging modality for early rectal cancer.Magnetic resonance imaging (MRI) is useful for assessing the mesorectum and the mesorectal fascia which has useful prognostic significance and for early identification of local recurrence.Computerized tomography (CT) of the chest,abdomen and pelvis is used to rule out distant metastasis.Identification of the malignant nodes using EUS,CT and MRI is based on the size,morphology and internal characteristics but has drawbacks.Most of the common imaging techniques are suboptimal for imaging following chemoradiation as they struggle to differentiate fibrotic changes and tumor.In this situation,EUS and MRI may provide complementary information to decide further treatment.Functional imaging using positron emission tomography (PET) is useful,particularly PET/CT fusion scans to identify areas of the functionally hot spots.In the current state,imaging has enabled the multidisciplinary team of surgeons,oncologists,radiologists and pathologists to decide on the patient centered management of rectal cancer.In future,functional imaging may play an active role in identifying patients with lymph node metastasis and those with residual and recurrent disease following neoadjuvant chemoradiotherapy.

    Although rectal and anal cancers are anatomically close, they are distinct entities with different histologic features, risk factors, staging systems, and treatment pathways. Imaging is at the core of initial clinical staging of these cancers and most commonly includes magnetic resonance imaging for local-regional staging and computed tomography for evaluation of metastatic disease. The details of the primary tumor and involvement of regional lymph nodes are crucial in determining if and how radiation therapy should be used in treatment of these cancers. Unfortunately, available imaging modalities have been shown to have imperfect accuracy for identification of nodal metastases and imaging features other than size. Staging of nonmetastatic rectal cancers is dependent on the depth of invasion (T stage) and the number of involved regional lymph nodes (N stage). Staging of nonmetastatic anal cancers is determined according to the size of the primary mass and the combination of regional nodal sites involved; the number of positive nodes at each site is not a consideration for staging. Patients with T3 rectal tumors and/or involvement of perirectal, mesenteric, and internal iliac lymph nodes receive radiation therapy. Almost all anal cancers warrant use of radiation therapy, but the extent and dose of the radiation fields is altered on the basis of both the size of the primary lesion and the presence and extent of nodal involvement. The radiologist must recognize and report these critical anatomic and staging distinctions, which affect use of radiation therapy in patients with anal and rectal cancers.

Many reports have indicated that patients suffering from cancer demonstrate decreased antitumor immune responses as well as a high prevalence of T regulatory population. It has been reported that Foxp3+Tregs exert suppression by cell contact-dependent mechanisms which are mediated by soluble factors such as immunosuppressive cytokines like IL-10, TGF-​B and IL-35. Consequently there is a great need to identify prognostic and diagnostic biomarkers of regulatory T cells for vaccine and drug development. Methods: In this study IL-10, TGF-B, IL-35 and Foxp3 mRNA gene expression has been measured in peripheral blood of 40 breast cancer patients and 40 normal age-matched women using quantitative real-time PCR (qRT-PCR method with Master Mix reaction containing SYBER Green. GAPDH gene was used as housekeeping gene. Results: Our data demonstrated a significant up-regulation of IL-10, TGF-​B, P35, EBI3 and Foxp3 gene expression in patients’ peripheral blood compared to normal healthy controls (p<0.05. Conclusion: The data suggests that the immune system is suppressed in breast cancer patients, which may be due to elevated Treg cells population. These results may be useful for diagnostic or therapeutic purposes. However it may require more investigations

    Outcomes of hepatocellular carcinoma (HCC) lesions >3.0 cm in size including Barcelona Clinic Liver Cancer (BCLC) stage B after radiofrequency ablation (RFA) with a single electrode remain unsatisfactory. This study aimed to investigate the outcomes of RFA with multiple electrodes (ME-RFA) for HCC tumors 3.1-7.0 cm in size and BCLC stage B. This retrospective study included 70 consecutive patients with 58 medium- (3.1-5.0 cm) and 17 large- (5.1-7.0 cm) sized HCCs after ME-RFA using a controller. Outcomes in terms of complete response, primary technique effectiveness, local tumor progression, and overall survival were investigated. After 1-4 applications of ME-RFA, the rates of complete response and PTE in medium-sized tumors were 79.3% and 91.4%, respectively, and in large tumors were 76.5% and 94.1%, respectively. Overall, the major complication rate was 5.7%. After a median 21-month follow-up period, both two- and three-year estimated overall survival rates were above 80%. There were no significant differences in overall survival and local tumor progression rates between medium- and large-size tumors and among BCLC stages A, B1 and B2. A complete response to ME-RFA was the only significant factor associated with improved survival (p=0.008). In conclusion, ME-RFA can effectively treat 3.1-7.0-cm sized HCCs with a comparable outcome between medium- and large-size tumors and among BCLA stages A to B2. PMID:26989656

    Full Text Available Abstract Background Routine data from cancer registries often lack information on stage of cancer, limiting their use. This study aimed to determine whether or not it is feasible to add cancer staging data to the routine data collections of a population-based Western Australian Cancer Registry (WACR. Methods For each of the five most common cancer types (prostate, colorectal, melanoma, breast and lung cancers, 60 cases were selected for staging. For the 15 next most common cancer types, 20 cases were selected. Four sources for collecting staging data were used in the following order: the WACR, the hospital based cancer registries (HBCRs, hospital medical records, and letters to treating doctors. If the case was unable to be fully staged, due to lack of information on regional lymph node invasion or distant metastases, we made the following assumptions. Cases which had data available for tumour (T and regional lymph nodes (N, but no assessment of distant metastasis (MX were assumed to have no distant metastases (M0. Cases which had data for T and M, but no assessment of regional nodal involvement (NX were assumed to have no regional nodal involvement (N0. Results The main focus of this project was the process of collecting staging data, and not the outcomes. For ovary, cervix and uterus cancers the existence of a HBCR increased the stageable proportion of cases so that staging data for these cancers could be incorporated into the WACR immediately. Breast and colorectal cancer could also be staged with adequate completeness if it were assumed that MX = M0. Similarly, melanoma and prostate cancer could be staged adequately if it were assumed that NX = N0 and MX = M0. Some cases of stomach, lung, pancreas, thyroid, testis and kidney cancers could be staged, but additional clinical input – on pathology request forms, for example – would be required to achieve useable levels of completeness. For the remaining cancer types either staging is widely

    OBJECTIVE To investigate the relationship between the clinicopathological stage and serum prostate specific antigen (PSA) concentration and PSA density (PSAD) in patients with prostate cancer.METHODS The clinicopathological stage was determined on the basis of a pathological examination and clinical data in 65 prostate cancer patients treated by radical prostatectomy. PSA and PSAD were measured before the operation. The Spearman rank correlation was applied to evaluate the relationship between the clinicopathological stage, serum PSA concentration and PSAD.RESULTS Patients with higher PSA and PSAD were significantly more likely to have higher clinical stages, a higher Gleason score, positive surgical margins, capsular penetration, and seminal vesicle invasion (each P<0.05).But there was no significant association between PSA and lymph node metastasis (P=0.053). The levels of serum PSA concentration and PSAD were significantly correlated with the clinical stage (P<0.05) in the prostate cancer patients.CONCLUSION The level of both PSA and PSAD were significantly correlated with the clinical stage (P<0.05) in the prostate cancer patients. But PSAD may be a more powerful predictor of clinical stage and prognosis than PSA.

    Imaging plays an increasingly important role in the staging and management of colorectal cancer. In recent years, magnetic resonance imaging (MRI) has supplanted transrectal ultrasound as the preferred modality for the locoregional staging of rectal cancer. Furthermore, the advent of both diffusion-weighted imaging and hepatobiliary contrast agents has significantly enhanced the ability of MRI to detect colorectal liver metastases. In clinical practice, MRI routinely provides prognostic information, helps to guide surgical strategy, and determines the need for neoadjuvant therapies related to both the primary tumor and metastatic disease. Expanding on these roles for MRI, positron emission tomography (PET)/MRI is the newest clinical hybrid imaging modality and combines the metabolic information of PET with the high soft tissue contrast of MRI. The addition of PET/MRI to the clinical staging armamentarium has the potential to provide comprehensive state-of-the-art colorectal cancer staging in a single examination. PMID:27582645

    The H5 study of supradiaphragmatic Hodgkin's disease in clinical stages I-II consisted of two controlled trials adapted to patients considered to have either favorable or unfavorable characteristics, based on prognostic factors identified in two former studies by the European Organization for Research and Treatment of Cancer. Of 494 patients, 257 who were classified as having unfavorable prognosis qualified for the more intensive treatment and consequently were spared a staging laparotomy. They were randomized either to total nodal irradiation (TNI) (132 patients) or to treatment with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) alternated with mantle irradiation (MOPP X 3-mantle irradiation-MOPP X 3; 3M) (125 patients). In complete responders (96%), the 6-year relapse-free survival was 77% in the TNI arm and 91% in the 3M arm (P = .02). Relapses in the initially involved and irradiated mantle area were less frequent in patients started on MOPP. The 6-year actuarial total survival (TS) (TNI, 82%, and 3M, 89%; P = .05) appeared to favor the 3M arm, but this difference disappeared when patients dying from causes unrelated to cancer were excluded from analysis. In men less than or equal to 40 years old, there was no difference in relapse-free survival, freedom from disease progression, or TS between the groups receiving TNI and 3M. Thus, TNI is a short and appealing treatment, especially because it preserves fertility. The same observation was true in women less than or equal to 40 years old. In addition, even irradiation less than TNI, which is meant to spare the ovaries, provided a TS similar to that for 3M.

    The aim of this retrospective study was to determine if some features of baseline {sup 18}F-FDG PET images, including volume and heterogeneity, reflect clinical, histological or immunohistochemical characteristics in patients with stage II or III breast cancer (BC). Included in the present retrospective analysis were 171 prospectively recruited patients with stage II/III BC treated consecutively at Saint-Louis hospital. Primary tumour volumes were semiautomatically delineated on pretreatment {sup 18}F-FDG PET images. The parameters extracted included SUV{sub max}, SUV{sub mean}, metabolically active tumour volume (MATV), total lesion glycolysis (TLG) and heterogeneity quantified using the area under the curve of the cumulative histogram and textural features. Associations between clinical/histopathological characteristics and {sup 18}F-FDG PET features were assessed using one-way analysis of variance. Areas under the ROC curves (AUC) were used to quantify the discriminative power of the features significantly associated with clinical/histopathological characteristics. T3 tumours (>5 cm) exhibited higher textural heterogeneity in {sup 18}F-FDG uptake than T2 tumours (AUC <0.75), whereas there were no significant differences in SUV{sub max} and SUV{sub mean}. Invasive ductal carcinoma showed higher SUV{sub max} values than invasive lobular carcinoma (p = 0.008) but MATV, TLG and textural features were not discriminative. Grade 3 tumours had higher FDG uptake (AUC 0.779 for SUV{sub max} and 0.694 for TLG), and exhibited slightly higher regional heterogeneity (AUC 0.624). Hormone receptor-negative tumours had higher SUV values than oestrogen receptor-positive (ER-positive) and progesterone receptor-positive tumours, while heterogeneity patterns showed only low-level variation according to hormone receptor expression. HER-2 status was not associated with any of the image features. Finally, SUV{sub max}, SUV{sub mean} and TLG significantly differed among the three

    To determine failure patterns and survival outcomes of T4N0-1 non-small cell lung cancer (NSCLC) treated with definitive radiotherapy. Ninety-five patients with T4N0-1 NSCLC who received definitive radiotherapy with or without chemotherapy from May 2003 to October 2014 were retrospectively reviewed. The standard radiotherapy scheme was 66 Gy in 30 fractions. The main concurrent chemotherapy regimen was 50 mg/m2 weekly paclitaxel combined with 20 mg/m2 cisplatin or AUC 2 carboplatin. The primary outcome was overall survival (OS). Secondary outcomes were failure patterns and toxicities. The median age was 64 years (range, 34 to 90 years). Eighty-eight percent of patients (n = 84) had an Eastern Cooperative Oncology Group performance status of 0-1, and 42% (n = 40) experienced pretreatment weight loss. Sixty percent of patients (n = 57) had no metastatic regional lymph nodes. The median radiation dose was EQD2 67.1 Gy (range, 56.9 to 83.3 Gy). Seventy-one patients (75%) were treated with concurrent chemotherapy; of these, 13 were also administered neoadjuvant chemotherapy. At a median follow-up of 21 months (range, 1 to 102 months), 3-year OS was 44%. The 3-year cumulative incidences of local recurrence and distant recurrence were 48.8% and 36.3%, respectively. Pretreatment weight loss and combined chemotherapy were significant factors for OS. Acute esophagitis over grade 3 occurred in three patients and grade 3 chronic esophagitis occurred in one patient. There was no grade 3-4 radiation pneumonitis. Definitive radiotherapy for T4N0-1 NSCLC results in favorable survival with acceptable toxicity rates. Local recurrence is the major recurrence pattern. Intensity modulated radiotherapy and radio-sensitizing agents would be needed to improve local tumor control.

    CT or MRT is performed in preoperative staging of laryngeal cancer. These methods are used in assessment of the deep tissues and cartilage of the larynx, but cannot compete with laryngoscopy in the evaluation of the laryngeal surface. The purpose of this study is to evaluate feasibility and clinical value of the 3-D reconstruction of the mucosal surface in laryngeal cancer. Twenty two patients with laryngeal cancer proved by means of surgical exploration (pathologic) or clinical examinations including laryngoscope, imaging studies and biopsy underwent preoperative staging with computed tomography(CT) and three dimensional(3D) CT reconstruction. The TNM classification of the American Joint Committee on Cancer was used to compare the imaging findings with pathologic or clinical staging. When the extension of primary tumor(T staging) was evaluated, the findings at only transaxial CT and those at pathologic or clinical examination were concordant in 8 of 14 cases(57.1%) of supraglottic tumor, and 3 of 6 cases(50%) of glottic tumor. The overall accuracy of CT with additional 3D-reconstruction was 85.7% for assessment of supraglottic tumor, and 66.6% for glottic tumor. 3D CT reconstruction after transaxial CT may improve outcome in preoperative staging of laryngeal cancer and has a potential value in guiding management decisions.

    Full Text Available The prediction of cancer staging in prostate cancer is a process for estimating the likelihood that the cancer has spread before treatment is given to the patient. Although important for determining the most suitable treatment and optimal management strategy for patients, staging continues to present significant challenges to clinicians. Clinical test results such as the pre-treatment Prostate-Specific Antigen (PSA level, the biopsy most common tumor pattern (Primary Gleason pattern and the second most common tumor pattern (Secondary Gleason pattern in tissue biopsies, and the clinical T stage can be used by clinicians to predict the pathological stage of cancer. However, not every patient will return abnormal results in all tests. This significantly influences the capacity to effectively predict the stage of prostate cancer. Herein we have developed a neuro-fuzzy computational intelligence model for classifying and predicting the likelihood of a patient having Organ-Confined Disease (OCD or Extra-Prostatic Disease (ED using a prostate cancer patient dataset obtained from The Cancer Genome Atlas (TCGA Research Network. The system input consisted of the following variables: Primary and Secondary Gleason biopsy patterns, PSA levels, age at diagnosis, and clinical T stage. The performance of the neuro-fuzzy system was compared to other computational intelligence based approaches, namely the Artificial Neural Network, Fuzzy C-Means, Support Vector Machine, the Naive Bayes classifiers, and also the AJCC pTNM Staging Nomogram which is commonly used by clinicians. A comparison of the optimal Receiver Operating Characteristic (ROC points that were identified using these approaches, revealed that the neuro-fuzzy system, at its optimal point, returns the largest Area Under the ROC Curve (AUC, with a low number of false positives (FPR = 0.274, TPR = 0.789, AUC = 0.812.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation.

    Gastric cancer imposes a considerable health burden around the globe despite its declining incidence. The disease is often diagnosed in advanced stages and is associated with a poor prognosis for patients. An in-depth understanding of the molecular underpinnings of gastric cancer has lagged behind many other cancers of similar incidence and morbidity, owing to our limited knowledge of germline susceptibility traits for risk and somatic drivers of progression (to identify novel therapeutic targets). A few germline (PLCE1) and somatic (ERBB2, ERBB3, PTEN, PI3K/AKT/mTOR, FGF, TP53, CDH1 and MET) alterations are emerging and some are being pursued clinically. Novel somatic gene targets (ARID1A, FAT4, MLL and KMT2C) have also been identified and are of interest. Variations in the therapeutic approaches dependent on geographical region are evident for localized gastric cancer-differences that are driven by preferences for the adjuvant strategies and the extent of surgery coupled with philosophical divides. However, greater uniformity in approach has been noted in the metastatic cancer setting, an incurable condition. Having realized only modest successes, momentum is building for carrying out more phase III comparative trials, with some using biomarker-based patient selection strategies. Overall, rapid progress in biotechnology is improving our molecular understanding and can help with new drug discovery. The future prospects are excellent for defining biomarker-based subsets of patients and application of specific therapeutics. However, many challenges remain to be tackled. Here, we review representative molecular and clinical dimensions of gastric cancer.

  20. Comorbidities and the Risk of Late-Stage Prostate Cancer

    Full Text Available The degree to which comorbidities affect the diagnosis of prostate cancer is not clear. The purpose of this study was to determine how comorbidities affect the stage at which prostate cancer is diagnosed in elderly white and black men. We obtained data from the Surveillance, Epidemiology, and End Results program of the National Cancer Institute merged with Medicare claims data. For each patient, we estimated associations between stage of disease at diagnosis and each of the 27 comorbidities. The sample included 2,489 black and 2,587 white men with staged prostate cancer. Coronary artery disease, benign hypertension, and dyslipidemia reduced the odds of late-stage prostate cancer. A prior diagnosis of peripheral vascular disease, severe renal disease, or substance abuse increased the odds of being diagnosed with late-stage disease. The study shows some effect modification by race, particularly among white men with substance abuse, cardiac conduction disorders, and other neurologic conditions. The strongest predictors of late-stage prostate cancer diagnosis for both white and black men were age at diagnosis of at least 80 years and lack of PSA screening. Comorbidities do affect stage at diagnosis, although in different ways. Four hypotheses are discussed to explain these findings.

    Background and Methods Circulating tumor cells (CTCs) constitute a useful approach for personalized medicine. Nevertheless, the isolation of these cells remains very challenging because they rarely circulate in the blood. Another current problem is the cancer-specific characterization of these cells, which requires a method that allows for the molecular and immunocytochemical profiling of all captured cells. The purpose of our proof of concept study was to investigate the use of a medical wire (CellCollector, GILUPI) to isolate CTCs in the blood of prostate cancer (PCa) patients, which allowed CTCs to be counted and molecularly characterized. Forty-three PCa patients in different stages and 11 control subjects were studied. Some randomized samples were used to detect tumor-associated transcripts, such as prostate-specific membrane antigen (PSMA), prostate-specific antigen (PSA) and epidermal growth factor receptor (EGFR), in the isolated CTCs. Results The mean CTC counts were 4.6 CTCs [range, 0–8] in patients with localized PCa, 16.8 CTCs [range, 10–25] in patients with locally advanced PCa, and 26.8 CTCs [range, 0–98] in patients with metastatic PCa. The median follow-up time was 24 months, and there was a significant difference in the cancer-specific survival rates. Patients with CTC counts under 5 CTCs lived significantly longer (p = 0.035) than patients with more than 5 CTCs. We also demonstrated that the captured CTCs could be molecularly characterized. We detected tumor-associated transcripts of EGFR and PSMA in patients with metastatic PCa in 42.8% and 14.3% of the analyzed samples, respectively. Conclusion Our results indicate that the sensitive isolation and molecular characterization of CTCs can be achieved ex vivo using the wire. Patients with more than 5 CTCs had a mortality risk that was 7.0 times greater that of those with fewer than 5 CTCs (hazard ratio 7.0 95%, CI 1.1–29.39). This proof of concept was required for the approval of the use of

    Full Text Available Abstract Background Second-line treatment of advanced non-small-cell lung cancer (NSCLC improves overall survival. There is a lack of data regarding the impact on patients' overall health condition. This prospective, non-interventional study evaluated performance status (PS and health-related quality of life (HR-QoL during second-line pemetrexed treatment in routine clinical practice. Methods Stage III/IV NSCLC patients who initiated second-line pemetrexed (standard vitamin and dexamethasone supplementation were observed for a maximum of 9 treatment cycles. The primary objective was to evaluate the proportion of patients achieving improvement of Karnofsky Index (KI of ≥ 10% (absolute or maintaining KI ≥ 80% after the second treatment cycle ("KI benefit response". HR-QoL was self-rated using the EuroQoL-5D questionnaire (EQ-5D. Factors potentially associated with KI benefit response were evaluated using logistic regression models. Results Of 521 eligible patients (73.5% Stage IV, median age 66.3 yrs, 36.1% ≥ 70 yrs, 62.0% with KI ≥ 80%, 471 (90.4% completed at least 2 treatment cycles. 58.0% (95%CI 53.6%;62.2% achieved KI benefit response after the second cycle. Patients with baseline KI ≥ 80%, no Grade 3/4 toxicities during the first 2 cycles, or combination regimen as prior first-line therapy were more likely to achieve a KI benefit response. EQ-5D scores improved over time. Grade 3/4 toxicities were reported in 23.8% of patients (mainly fatigue/asthenia 15.9%, neutropenia 8.7%. Conclusions In this large prospective, non-interventional study of second-line pemetrexed treatment in patients with advanced NSCLC, including 36% elderly patients ( ≥ 70 years, physician-rated PS and self-rated HR-QoL were maintained or improved in the majority of patients.

    2013-01-01

    Breast cancer is the most commonly diagnosed cancer in women in United States. From data of American Cancer Society from 2007 reported total of 178,480 women diagnosed with breast cancer. The death rate from breast cancer has decreased in North America over time, but still accounts for second highest cancer death, following lung cancer. Breast cancer is staged based on tumor size, nodal involvement, and distant metastasis like any other solid tumors. However clinical staging is not the only important factor in management of breast cancer. Various molecular features divides breast cancer into many subgroups - that act differently, and respond differently from therapy. Thus the focus of breast cancer treatment has evolved focusing on specific targets. The most important biologic markers in subtyping of breast cancer so far are hormone receptor positivity and HER2/neu protein expression. Five molecular subtypes using intrinsic gene set include Basal mRNA, HER2 + mRNA, Luminal AmRNA, Luminal B mRNA, and Normal-like mRNA. In addition, better understanding of genetic target of breast cancer has given us arsenal of personalized, and more effective treatment approach.This review will focus on examples that highlight several mechanism of tumorigenesis, giving us not just understanding of gene pathways and the molecular biology, that could lead us to therapeutic target. Several important molecular targets have been investigated in preclinical and clinical trials, others are yet to be explored. We will also describe genetic mechanisms discovery related to overcoming resistance to current targeted therapies in breast cancer, including hormone receptor expression and HER 2- neu amplification. We will also review other exciting developments in understanding of breast cancer, the tumor microenvironment and cancer stem cells, and targeting agents in that area. PMID:23288634

  10. Main clinical epidemiological features of lung cancer

    International Nuclear Information System (INIS)

    A descriptive and cross-sectional study of 95 patients with lung cancer, discharged from Neumology Service at 'Dr Juan Bruno Zayas Alfonso' General Hospital in Santiago de Cuba, was carried out from January, 2008 to December, 2008 in order to identify the main clinical epidemiological features of the aforementioned disease. A malignancy predominance among men aged between 56 and 65 years old, belonging to urban areas and being heavy smoker (out of 30 cigarettes per day over 30 years ), was found. Those affected without a confirmed histological type and IV clinical stage epidermoid carcinoma were predominant. Most of them had the opportunity to be treated. Increasing and intensifying health promotion and disease prevention campaigns were recommended so as to achieve the population to avoid or quit the smoking habit. (author)

    2011-05-01

    Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

    Directory of Open Access Journals (Sweden)

    I. V. Lukianov

    2014-07-01

    Full Text Available The choice of a technique of treatment of prostate cancer depends on the age of the patient, accompanying diseases and prevalence of tumoral process. The basic methods at an inspection stage at which the cancer stage is defined are: definition of prostate specific membrane antigen, rectal examination, results of the rectal ultrasound guided biopsy, prostate imaging methods and an estimation of a grade of a tumor. Nowadays one of the main directions of determining the treatment for various stages of tumor is the development of prognostic models based on the analysis of predictors for tumor expansion.

  16. The correlation of preoperative CT, MR imaging, and clinical staging (FIGO) with histopathology findings in primary cervical carcinoma

    International Nuclear Information System (INIS)

    The aim of this study was to compare the preoperative findings of abdominal/pelvic CT and MRI with the preoperative clinical International Federation of Obstetrics and Gynecology (FIGO) staging and postoperative pathology report in patients with primary cancer of the cervix. Thirty-six patients with surgical-pathological proven primary cancer of the cervix were retrospectively studied for preoperative staging by clinical examination, CT, and MR imaging. Studied parameters for preoperative staging were the presence of tumor, tumor extension into the parametrial tissue, pelvic wall, adjacent organs, and lymph nodes. The CT was performed in 32 patients and MRI (T1- and T2-weighted images) in 29 patients. The CT and MR staging were based on the FIGO staging system. Results were compared with histological findings. The group is consisted of stage 0 (in situ):1, Ia:1, Ib:8, IIa:2, IIb:12, IIIa:4, IVa:6, and IVb:2 patients. The overall accuracy of staging for clinical examination, CT, and MRI was 47, 53, and 86%, respectively. The MRI incorrectly staged 2 patients and did not visualize only two tumors; one was an in situ (stage-0) and one stage-Ia (microscopic) disease. The MRI is more accurate than CT and they are both superior to clinical examination in evaluating the locoregional extension and preoperative staging of primary cancer of the cervix. (orig.)

  17. Preoperative infusional chemoradiation therapy for stage T3 rectal cancer

    International Nuclear Information System (INIS)

    Purpose: To evaluate preoperative infusional chemoradiation for patients with operable rectal cancer. Methods and Materials: Preoperative chemoradiation therapy using infusional 5-fluorouracil (5-FU), (300 mg/m2/day) together with daily irradiation (45 Gy/25 fractions/5 weeks) was administered to 77 patients with clinically Stage T3 rectal cancer. Endoscopic ultrasound confirmed the digital rectal exam in 63 patients. Surgery was performed approximately 6 weeks after the completion of chemoradiation therapy and included 25 abdominoperineal resections and 52 anal-sphincter-preserving procedures. Results: Posttreatment tumor stages were T1-2, N0 in 35%, T3 N0 in 25%, and T1-3, N1 in 11%; 29% had no evidence of tumor. Local tumor control after chemoradiation was seen in 96% (74 out of 77); 2 patients had recurrent disease at the anastomosis site and were treated successfully with abdominoperineal resection. Overall, pelvic control was obtained in 99% (76 out of 77). The survival after chemoradiation was higher in patients without node involvement than in those having node involvement (p = n.s.). More patients with pathologic complete responses or only microscopic foci survived than did patients who had gross residual tumor (p = 0.07). The actuarial survival rate was 83% at 3 years; the median follow-up was 27 months, with a range of 3 to 68 months. Acute, perioperative, and late complications were not more numerous or more severe with chemoradiation therapy than with traditional radiation therapy (XRT) alone. Conclusions: Excellent treatment response allowed two-thirds of the patients to have an anal-sphincter-sparing procedure. Gross residual disease in the resected specimen indicates a poor prognosis, and therapies specifically targeting these patients may improve survival further

    In 2010, there were an estimated 43,140 new cases of pancreatic ductal adenocarcinoma and 36,800 deaths from pancreatic cancer in the United States [1]. This represents the 10th most common cancer diagnosis but the 4th most common cause of cancer-related death among men and women (6% of all cancer-related deaths), highlighting the disproportionate mortality associated with this diagnosis [2]. Why is Staging so Important? Sadly, only 20% patients are “resectable” at the time of diagnosis...

  3. Can advanced-stage ovarian cancer be cured?

    Narod, Steven

    2016-04-01

    Approximately 20% of women with advanced-stage ovarian cancer survive beyond 12 years after treatment and are effectively cured. Initial therapy for ovarian cancer comprises surgery and chemotherapy, and is given with the goal of eradicating as many cancer cells as possible. Indeed, the three phases of therapy are as follows: debulking surgery to remove as much of the cancer as possible, preferably to a state of no visible residual disease; chemotherapy to eradicate any microscopic disease that remains present after surgery; and second-line or maintenance therapy, which is given to delay disease progression among patients with tumour recurrence. If no cancer cells remain after initial therapy is completed, a cure is expected. By contrast, if residual cancer cells are present after initial treatment, then disease recurrence is likely. Thus, the probability of cure is contingent on the combination of surgery and chemotherapy effectively eliminating all cancer cells. In this Perspectives article, I present the case that the probability of achieving a cancer-free state is maximized through a combination of maximal debulking surgery and intraperitoneal chemotherapy. I discuss the evidence indicating that by taking this approach, cures could be achieved in up to 50% of women with advanced-stage ovarian cancer. PMID:26787282

    Full Text Available The stage of urinary bladder cancer is an important factor in determining prognosis of the disease. This prospective study was performed to determine the stage of bladder cancer at first presentation at the Rizgary Hospital in the Erbil governorate in Iraqi Kurdistan. We evaluated 72 patients with bladder cancer. The grades and stages of bladder cancer of these patients were determined through physical examination and investigations. We found that 47.2% of patients had superficial cancer, 19.4% had tumor with invasion into the lamina propria and 30.6% of patients had tumor with invasion to muscle wall. Regional or distant metastases were found in 2.8% of patients. Well differentiated tumor was seen in 44.4% of the patients, moderately differentiated tumor was found in 38.9% and poorly differentiated tumor was found in 16.7% of the patients. Our study suggests that bladder cancer is diagnosed at a relatively early stage in the Erbil governorate. However, the situation can be further improved by adopting proper screening programs and performing appropriate investigations.

    The study included 26 patients with FIGO stage Ia1-Ib1 cervical cancer who underwent fertility-sparing surgery (transabdominaltrachelectomy). To visualize sentinel lymph nodes, lymphoscintigraphy with injection of 99mTc-labelled nanocolloid was performed the day before surgery. Intraoperative identification of sentinel lymph nodes using hand-held gamma probe was carried out to determine the radioactive counts over the draining lymph node basin. The sentinel lymph node detection in cervical cancer patients contributes to the accurate clinical assessment of the pelvic lymph node status, precise staging of the disease and tailoring of surgical treatment to individual patient.

  7. Analyzing proteasomal subunit expression reveals Rpt4 as a prognostic marker in stage II colorectal cancer.

    LENUS (Irish Health Repository)

    2012-02-01

    Colorectal cancer is a leading cause of cancer-related deaths worldwide. Early diagnosis and treatment of colorectal cancer is the key to improving survival rates and as such a need exists to identify patients who may benefit from adjuvant chemotherapy. The dysregulation of the ubiquitin-proteasome system (UPS) has been implicated in oncogenesis and cancer cell survival, and proteasome inhibitors are in clinical use for a number of malignancies including multiple myeloma. In our study, we examined the protein expression of several key components of the UPS in colorectal cancer using immunohistochemistry to determine expression levels of ubiquitinylated proteins and the proteasomal subunits, 20S core and Rpt4 in a cohort of 228 patients with colon cancer. Multivariate Cox analysis revealed that neither the intensity of either ubiquitinylated proteins or the 20S core was predictive in either Stage II or III colon cancer for disease free survival or overall survival. In contrast, in Stage II patients increased Rpt4 staining was significantly associated with disease free survival (Cox proportional hazard ratio 0.605; p = 0.0217). Our data suggest that Rpt4 is an independent prognostic variable for Stage II colorectal cancer and may aid in the decision of which patients undergo adjuvant chemotherapy.

    . Methods:A retrospective analysis was performed on the clinical data from 196 patients of stages ⅠB2-ⅡB cervical cancer admitted to First Maternity and Infant Hospital Affiliated to Tongji University during January 2003 to June 2013. Patients were divided into two groups: 71 cases received pre-surgical NACT based on platinum and taxol (NACT group) and 125 cases received primary surgical treatment (PST group) without pre-surgical NACT. Both groups received radical hysterectomy, bilateral salpingo-oophorectomy(age>45 years old) plus pelvic lymph node dissection with or without para-aortic lymphadenectomy. In the NACT group, reduction in tumor size was observed after chemotherapy. Pelvic lymph node metastasis, depth of myometral invasion, lympho-vascular space invasion, bulky tumor, parametrial invasion, positive vaginal resection margin and survival rates were compared between the two groups. Results:In NACT group, data missing were 15 cases, 4 cases (7.1%) had complete remission (CR), 27 cases (48.2%) had partial remission (PR), 18 cases (32.1%) were stable disease (SD) and 7 cases (12.5%) were progression of disease (PD). Compared with the PST group, patients in NACT group had greater reduction in the size of uterus and width of cervical lesion, more lymph nodes dissected, and fewer bulky tumors with≥50%thickness myometrial invasion (all P0.05). Conclusions:Neoadjuvant chemotherapy has certain recent clinical curative effects, however, did not improve the overall survival rate, therefore, doctors should carefully consider the clinical application of NACT. Neoadjuvant chemotherapy has a certain effect on controling pathologic risk factors of the bulky cervical cancer after surgery. Accordingly, for massive type, surgery after neoadjuvant chemotherapy will be a safe treatment.

MÉTODOS: Foram analisados, de forma retrospectiva, os dados de pacientes tratados no Serviço de Cirurgia Torácica do Hospital São Lucas da Pontifícia Universidade Católica do Rio Grande do Sul, e foram calculados a sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e acurácia para os estádios clínicos IA, IB e IIB. O índice kappa foi utilizado para determinar a concordância entre os estadiamentos clínico e patológico. RESULTADOS: Dentre os 92 pacientes estudados, 33,7% foram classificados como estádio clínico IA, 50% como IB e 16,3% como IIB. A concordância entre os estadiamentos clínico e patológico foi de 67,5% para IA, 54,3% para IB e 66,6% para IIB. O estadiamento clínico teve maior acurácia no estádio IA, e um kappa de 0,74 neste caso confirma uma substancial associação com o estadiamento patológico. A dificuldade em avaliar doença metastática linfonodal é responsável pela baixa concordância em pacientes com estádio clínico IB. CONCLUSÕES: A concordância entre os estadiamentos clínico e patológico é baixa, e, freqüentemente, os pacientes são subestadiados (no presente estudo, somente um caso foi superestadiado.

    International Nuclear Information System (INIS)

    We have performed laser-radiation combined therapy for stage I and II laryngeal cancers in order to preserve the larynx. In the present study, we retrospectively investigate the factors affecting the preservation of the larynx in stage II laryngeal cancer. The subjects consisted of 34 patients with stage II laryngeal cancer treated between 1988 and 1996 and observed for more than 2 years. Cases with involvement of the ventricle or false cord and those with impaired vocal cord movement showed a tendency towards the loss of their larynx. Moreover, these failures required a longer period to irradiate 1 gray on average than cases which led to a successful preservation of the larynx. (author)

    Full Text Available Abstract Introduction Radionecrosis (post-radiotherapy laryngeal submucosal inflammation and necrosis is a complication of (chemo radiotherapy for hypopharyngeal cancer that is difficult to differentiate from tumor recurrence. Case presentation A 67-year-old Japanese man presented with a condition extremely difficult to diagnose differentially as radionecrosis or tumor recurrence after radiotherapy for hypopharyngeal cancer. Although tumor recurrence was suspected from clinical conditions and computed tomography findings, pathologic analysis revealed no evidence of tumor recurrence, and successful therapy with steroids and antibiotics reduced the mucosal edema. Conclusion Our findings emphasize the wide spectrum of radiographic presentation of radionecrosis after chemoradiation of stage IV hypopharyngeal cancer.

  13. Endoscopic ultrasound in the diagnosis and staging of pancreatic cancer

    2009-09-01

    Full Text Available Pancreatic cancer is the 5th leading cause of cancer-related death in Western countries. The 5-year survival rate is approximately 4%, without significant changes over the last 50 years. This poor survival rate and bad prognosis are associated with the diagnosis of advanced-stage disease, which precludes the only potential curative treatment - surgical resection. In this setting, the main objective in the management of pancreatic cancer is to perform an early diagnosis and a correct staging of the disease. Endoscopic ultrasonography (EUS appears to be an essential tool for the diagnosis and staging of pancreatic cancer. EUS diagnostic accuracy for detecting pancreatic tumors ranges from 85 to 100%, clearly superior to other imaging techniques. EUS accuracy for the local staging of pancreatic cancer ranges from 70 to 90%, superior or equivalent to other imaging modalities. EUS-guided fine-needle aspiration allows a cyto-histological diagnosis in nearly 90% of cases, with a very low complication rate. At present, the formal indications for EUS-guided fine-needle aspiration are the necessity of palliative treatment or whenever the possibility of neoadjuvant treatment is present. It could be also indicated to differentiate pancreatic adenocarcinoma from other pancreatic conditions, like lymphoma, metastasis, autoimmune pancreatitis or chronic pancreatitis. We can conclude that EUS is an essential tool in the management of patients with pancreatic tumors.

    Surgical treatment of cervical cancer has been a cornerstone in the management of this malignancy for more than 100 years. Today, for early-stage and low-risk cervical cancer, surgery is still considered the gold standard. If the preoperative assessment of the tumor reveals a situation prompting postoperative adjuvant radiochemotherapy, the latter should be planned as the primary treatment option, being preceded by staging laparoscopy including pelvic and paraaortic lymph node dissection. As an alternative to the open approach, the definitive surgical treatment should be either performed laparoscopically, or be laparoscopic-assisted, or laparoscopically robotic-assisted.

    To evaluate whole-body MRI with diffusion-weighted sequence (WB-DWI/MRI) for staging and assessing operability compared with CT and FDG-PET/CT in patients with suspected ovarian cancer. Thirty-two patients underwent 3-T WB-DWI/MRI, {sup 18} F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and CT before diagnostic open laparoscopy (DOL). Imaging findings for tumour characterisation, peritoneal and retroperitoneal staging were correlated with histopathology after DOL and/or open surgery. For distant metastases, FDG-PET/CT or image-guided biopsies were the reference standards. For tumour characterisation and peritoneal staging, WB-DWI/MRI was compared with CT and FDG-PET/CT. Interobserver agreement for WB-DWI/MRI was determined. WB-DWI/MRI showed 94 % accuracy for primary tumour characterisation compared with 88 % for CT and 94 % for FDG-PET/CT. WB-DWI/MRI showed higher accuracy of 91 % for peritoneal staging compared with CT (75 %) and FDG-PET/CT (71 %). WB-DWI/MRI and FDG-PET/CT showed higher accuracy of 87 % for detecting retroperitoneal lymphadenopathies compared with CT (71 %). WB-DWI/MRI showed excellent correlation with FDG-PET/CT (κ = 1.00) for detecting distant metastases compared with CT (κ = 0.34). Interobserver agreement was moderate to almost perfect (κ = 0.58-0.91). WB-DWI/MRI shows high accuracy for characterising primary tumours, peritoneal and distant staging compared with CT and FDG-PET/CT and may be valuable for assessing operability in ovarian cancer patients.

    Lung cancer staging according to the TNM system is based on morphological assessment of the primary cancer, lymph nodes and metastases. All aspects of this important oncological classification are measurable with MRI. Pulmonary nodules can be detected at the clinically relevant size of 4-5 mm in diameter. The extent of mediastinal, hilar and supraclavicular lymph node affection can be assessed at the same time. The predominant metastatic spread to the adrenal glands and spine can be detected in coronal orientation during dedicated MRI of the lungs. Search focused whole body MRI completes the staging. Various additional MR imaging techniques provide further functional and clinically relevant information during a single examination. In the oncological context the most important techniques are imaging of perfusion and tumor motion. Functional MRI of the lungs complements the pure staging and improves surgical approaches and radiotherapy planning. (orig.)

    Early diagnosis of pancreatic cancer remains a difficult task, and multiple imaging tests have been proposed over the years. The aim of this review is to describe the current role of endoscopic ultrasound (EUS) for the diagnosis and staging of patients with pancreatic cancer. A detailed search...... of MEDLINE between 1980 and 2007 was performed using the following keywords: pancreatic cancer, endoscopic ultrasound, diagnosis, and staging. References of the selected articles were also browsed and consulted. Despite progress made with other imaging methods, EUS is still considered to be superior...... for the detection of clinically suspected lesions, especially if the results of other cross-sectional imaging modalities are equivocal. The major advantage of EUS is the high negative predictive value that approaches 100%, indicating that the absence of a focal mass reliably excludes pancreatic cancer...

    Full Text Available Abstract Background Previous studies have documented lower breast cancer survival among women with lower socioeconomic status (SES in the United States. In this study, I examined the extent to which socioeconomic disparity in breast cancer survival was explained by stage at diagnosis, treatment, race and rural/urban residence using the Surveillance, Epidemiology, and End Results (SEER data. Methods Women diagnosed with breast cancer during 1998-2002 in the 13 SEER cancer registry areas were followed-up to the end of 2005. The association between an area-based measure of SES and cause-specific five-year survival was estimated using Cox regression models. Six models were used to assess the extent to which SES differences in survival were explained by clinical and demographical factors. The base model estimated the hazard ratio (HR by SES only and then additional adjustments were made sequentially for: 1 age and year of diagnosis; 2 stage at diagnosis; 3 first course treatment; 4 race; and 5 rural/urban residence. Results An inverse association was found between SES and risk of dying from breast cancer (p Conclusion Stage at diagnosis, first course treatment and race explained most of the socioeconomic disparity in breast cancer survival. Targeted interventions to increase breast cancer screening and treatment coverage in patients with lower SES could reduce much of socioeconomic disparity.

  2. Imaging vascular function for early stage clinical trials using dynamic contrast-enhanced magnetic resonance imaging

    International Nuclear Information System (INIS)

    Many therapeutic approaches to cancer affect the tumour vasculature, either indirectly or as a direct target. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has become an important means of investigating this action, both pre-clinically and in early stage clinical trials. For such trials, it is essential that the measurement process (i.e. image acquisition and analysis) can be performed effectively and with consistency among contributing centres. As the technique continues to develop in order to provide potential improvements in sensitivity and physiological relevance, there is considerable scope for between-centre variation in techniques. A workshop was convened by the Imaging Committee of the Experimental Cancer Medicine Centres (ECMC) to review the current status of DCE-MRI and to provide recommendations on how the technique can best be used for early stage trials. This review and the consequent recommendations are summarised here. (orig.)

    Many therapeutic approaches to cancer affect the tumour vasculature, either indirectly or as a direct target. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has become an important means of investigating this action, both pre-clinically and in early stage clinical trials. For such trials, it is essential that the measurement process (i.e. image acquisition and analysis) can be performed effectively and with consistency among contributing centres. As the technique continues to develop in order to provide potential improvements in sensitivity and physiological relevance, there is considerable scope for between-centre variation in techniques. A workshop was convened by the Imaging Committee of the Experimental Cancer Medicine Centres (ECMC) to review the current status of DCE-MRI and to provide recommendations on how the technique can best be used for early stage trials. This review and the consequent recommendations are summarised here. (orig.)

    Endoscopic ultrasonography (EUS) is used for preoperative assessment of gastric cancer. However, recent studies suggested that EUS staging accuracy is lower than previously thought. We aimed to assess EUS efficacy and image characteristics in preoperative gastric cancer T staging.A retrospective review of clinical and imaging features of 232 gastric carcinoma patients who underwent preoperative EUS assessment of T stage was performed. Only cases with tumor-free resection margin status and no metastases were enrolled. Comparisons of preoperative EUS and postoperative histopathological stagings were also performed to identify vital EUS image features for evaluating gastric carcinoma.EUS accuracy for T staging was 64.2% (149/232) with the highest accuracy for T3 (75.0%). Enlarged lymph nodes, well differentiated histological type and Borrmann IV type were associated with diagnostic accuracy in predicting tumor invasion. Although no factors were associated with overstaging, circumferential lesions ≥1/2, signet ring cell adenocarcinoma, and Borrmann IV type had significantly higher risks of understaging. Gastric wall outer edge irregularity was also an indicator of serosal involvement with a sensitivity of 82.0%. The pancreas and colon were more frequent disease extension sites than previously predicted.Although EUS is likely the best and most accurate option that we have used to stage gastric cancer, the finding that factors including circumferential lesions, signet ring cell adenocarcinoma, and Borrmann IV type carcinoma were more frequently related to incorrect staging warrants attention.

  11. Guide to clinical PET in oncology: Improving clinical management of cancer patients

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) has an approximately 50 year-history. It was developed as a tool of medical science to quantitatively measure metabolic rates of bio-substances in vivo and in particular the number of receptors in neuroscience. Until the late 1990s PET was, in most cases, research oriented activity. In 2001, positron emission tomography/X ray computed tomography (PET/CT) hybrid imaging system became commercially available. An era of clinical PET then emerged, in which PET images were utilized for clinical practice in the treatment and diagnosis of cancer patients. PET imaging could recognize areas of abnormal metabolic behaviour of cancers in vivo, and the addition of CT imaging underlines the site of malignancy. More accurate and precise interpretation of cancer lesions can therefore be performed by PET/CT imaging than PET or CT imaging alone. Clinical PET, in particular with fluorine-18-fluorodeoxyglucose (18F-FDG), has already proven itself to have considerable value in oncology. The indications include malignant lymphoma and melanoma, head and neck cancers, oesophageal cancer, breast cancer, lung cancer and colorectal cancer, and it is still being expanded. The roles of clinical PET could be for 1) preoperative staging of cancers, 2) differentiation between residual tumour and scarring, 3) demonstration of suspected recurrences, 4) monitoring response to therapy, 5) prognosis and 6) radiotherapy treatment planning. Clinical PET can be used to illustrate exactly which treatment should be applied for a cancer patient as well as where surgeons should operate and where radiation oncologists should target radiation therapy. An almost exponential rise in the introduction of clinical PET, as well as the installation of PET/CT has been seen throughout the world. Clinical PET is currently viewed as the most powerful diagnostic tool in its field. This IAEA-TECDOC presents an overview of clinical PET for cancer patients and a relevant source of

  12. The Role of Lymphadenectomy in Surgical Staging of Endometrial Cancer

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Surgical staging, including lymph node sampling, for endometrial cancer was adopted by the International Federation of Gynecology and Obstetrics (FIGO in 1988 based on reports demonstrating diagnostic and therapeutic advantages. This review focuses on the incidence of lymph node metastasis, risk factors for lymph node involvement, the effect of lymph node metastasis on prognosis, the therapeutic effect and diagnostic usefulness of lymphadenectomy, risks of lymph node dissection, and future directions in surgical staging of endometrial cancer. Surgical staging identifies most patients with extrauterine disease as well as uterine risk factors for recurrence, thereby allowing for a more informed approach to postoperative adjuvant therapy. Lymphadenectomy as a part of surgical staging is not required in patients assessed intraoperatively to be at low risk for lymph node metastasis (<2 cm grade 1 tumors with superficial myometrial invasion, however, a systematic lymph node dissection should be performed in most other patients with endometrial cancer. In the future, molecular markers may be useful to predict preoperatively tumor aggressiveness and lymph node metastasis. It is hoped that an approach of surgical staging with selective lymph node dissection will improve survival and spare patients additional surgical complications or unnecessary postoperative exposure to radiation and/or chemotherapy.

    2009-01-01

    Objective:To evaluate the current approaches for multimodality therapy for stage ⅠB cervical cancer. Methods:The relevant literature has served as a source for identified high or intermediate risks and management of stage ⅠB cervical cancer. Result:The high risks include pelvic lymph node metastasis (PLNM), positive resection margin (PRM), and the in-volvement of parametrium (IPM). The intermediate risks include deep stromal invasion (DSI), bulky tumor size ( BTS), lymphovascular space invasion (LVSI). Adeno-carcinomatous histo-type is the new risk feature relevant to poor prognoses. Both radical hysterectomy plus bilateral pelvic lymph node dissection(PLND) and radical radiotherapy have proven to be equally effec-tive. Surgery is more performed for stage ⅠB1 disease;radiotherapy or chemoradiotherapy is preferable for stage ⅠB2 disease. For patients with one high risk or two of intermediate risks, radical hysterectomy plus PLND followed by concurrent chemoradiotherapy can improve overall survival(OS) and disease-free survival (DFS). Conclusion:The management should be indi-vidualized for stage ⅠB cervical cancer. The optimized multidisciplinary therapy can benefit pa-tients with the best cure and minimum morbidity and complications.

  15. Fluorodeoxyglucose positron emission tomography-computed tomography in evaluation of pelvic and para-aortic nodal involvement in early stage and operable cervical cancer: comparison with surgicopathological findings

    International Nuclear Information System (INIS)

    Nodal metastases in cervical cancer have prognostic implications. Imaging is used as an adjunct to clinical staging for evaluation of nodal metastases. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has an advantage of superior resolution of its CT component and detecting nodal disease based on increased glycolytic activity rather than node size. But there are limited studies describing its limitations in early stage cervical cancers. We have done meta-analysis with an objective to evaluate the efficacy of FDG PET/CT and its current clinical role in early stage and operable cervical cancer. Studies in which FDG PET/CT was performed before surgery in patients with early stage cervical cancers were included for analysis. PET findings were confirmed with histopathological diagnosis rather than clinical follow-up. The current data suggest that FDG PET/CT is suboptimal in nodal staging in early stage cervical cancer

  16. Regulatory manual for staging of cancer by CT

    International Nuclear Information System (INIS)

    The exact level for staging and making decisions about therapy that will be applied to cancer patients at the Servicio de Radiologia e Imagenes Medicas has been important for the Hospital Calderon Guardia. A template of report or manual has been suggested, with the information necessary for staging a particular type of cancer by analyzing the tomography of the patient. The TNM International System has been used to design the template of report, with a specific technical language and terminology unified theme for the oncologist and radiologist. This system is abstracted in the sixth edition of oncological staging manual of the American Joint Committee and its atlas; resources already acquired, and the helical CT scanner. The experience of the radiologist is critical, because he will be responsible to fill the document.

    A mounting body of evidence in cancer research suggests that the local microenvironment of tumor cells has a profound influence on cancer progression and metastasis. In vitro studies on the tumor microenvironment and its pharmacological modulation, however, are often hampered by the technical challenges associated with creating physiological cell culture environments that integrate cancer cells with the key components of their native niche such as neighboring cells and extracellular matrix (ECM) to mimic complex microarchitecture of cancerous tissue. Using early-stage breast cancer as a model disease, here we describe a biomimetic microengineering strategy to reconstitute three-dimensional (3D) structural organization and microenvironment of breast tumors in human cell-based in vitro models. Specifically, we developed a microsystem that enabled co-culture of breast tumor spheroids with human mammary ductal epithelial cells and mammary fibroblasts in a compartmentalized 3D microfluidic device to replicate microarchitecture of breast ductal carcinoma in situ (DCIS). We also explored the potential of this breast cancer-on-a-chip system as a drug screening platform by evaluating the efficacy and toxicity of an anticancer drug (paclitaxel). Our microengineered disease model represents the first critical step towards recapitulating pathophysiological complexity of breast cancer, and may serve as an enabling tool to systematically examine the contribution of the breast cancer microenvironment to the progression of DCIS to an invasive form of the disease.

    To evaluate the diagnostic performance of preoperative multiparametric MRI with extracapsular extension (ECE) risk-scoring in the assessment of prostate cancer tumour stage (T-stage) and prediction of ECE at final pathology. Eighty-seven patients with clinically localised prostate cancer scheduled for radical prostatectomy were prospectively enrolled. Multiparametric MRI was performed prior to prostatectomy, and evaluated according to the ESUR MR prostate guidelines by two different readers. An MRI clinical T-stage (cT{sub MRI}), an ECE risk score, and suspicion of ECE based on tumour characteristics and personal opinion were assigned. Histopathological prostatectomy results were standard reference. Histopathology and cT{sub MRI} showed a spearman rho correlation of 0.658 (p < 0.001) and a weighted kappa = 0.585 [CI 0.44;0.73](reader A). ECE was present in 31/87 (36 %) patients. ECE risk-scoring showed an AUC of 0.65-0.86 on ROC-curve for both readers, with sensitivity and specificity of 81 % and 78 % at best cutoff level (reader A), respectively. When tumour characteristics were influenced by personal opinion, the sensitivity and specificity for prediction of ECE changed to 61 %-74 % and 77 %-88 % for the readers, respectively. Multiparametric MRI with ECE risk-scoring is an accurate diagnostic technique in determining prostate cancer clinical tumour stage and ECE at final pathology. (orig.)

    To evaluate the impact of whole-body {sup 18}F-FDG PET/CT on initial staging of breast cancer in comparison to conventional staging modalities. This study included 102 breast cancer patients, 101 patients were eligible for evaluation. Preoperative whole-body staging with PET/CT was performed in patients with clinical stage ≥ T2 tumours or positive local lymph nodes (n = 91). Postoperative PET/CT was performed in patients without these criteria but positive sentinel lymph node biopsy (n = 10). All patients underwent PET/CT and a conventional staging algorithm, which included bone scan, chest X-ray and abdominal ultrasound. PET/CT findings were compared to conventional staging and the impact on therapeutic management was evaluated. PET/CT led to an upgrade of the N or M stage in overall 19 patients (19 %) and newly identified manifestation of breast cancer in two patients (2 %). PET/CT findings caused a change in treatment of 11 patients (11 %). This is within the range of recent studies, all applying conventional inclusion criteria based on the initial T and N status. PET/CT has a relevant impact on initial staging and treatment of breast cancer when compared to conventional modalities. Further studies should assess inclusion criteria beyond the conventional T and N status, e.g. tumour grading and receptor status. (orig.)

    Full Text Available In 2010, there were an estimated 43,140 new cases of pancreatic ductal adenocarcinoma and 36,800 deaths from pancreatic cancer in the United States [1]. This represents the 10th most common cancer diagnosis but the 4th most common cause of cancer-related death among men and women (6% of all cancer-related deaths, highlighting the disproportionate mortality associated with this diagnosis [2]. Why is Staging so Important? Sadly, only 20% patients are “resectable” at the time of diagnosis [3]. Pancreatic cancer is “resectable” if the tumor is confined to the pancreas without the encasement of adjacent surrounding major vessels, or distant metastases. Even among those patients who undergo resection for pancreatic cancer and have tumor-free margins, the 5-year survival rate after resection is 10-25% and the median survival is 15-19 months [3]. “Locally advanced pancreatic cancer” is defined as the tumor that has a local invasion: arterial (celiac trunk, hepatic artery, superior mesenteric artery or venous (portal vein, superior mesenteric vein but not metastasized, and represents about 25% of pancreatic cancer cases at presentation [4]. Locally advanced stage is associated with a median survival of 6-10 months. The vast majority of these patients develop metastatic disease within the first year of therapy. The tumor is considered “advanced” when it has metastasized to other organs, such as the liver or distant areas of the abdomen. Approximately 45% to 55% of patients are diagnosed at this stage. The prognosis of patients with advanced disease remains extremely poor, with a median survival of 6 months [5].

  5. Effects of repeated mammographic screening on breast cancer stage distribution

    International Nuclear Information System (INIS)

    A randomised controlled trial of mass screening for breast cancer by single-view mammography was begun in Sweden in 1977. All women aged 40 and older and resident in the counties of Koppaberg and Oestergoetland were enrolled. The present report is confined to the Oestergoetland study, which started in 1978 and comprised 92934 women. After randomisation, which was done on the basis of communities rather than individuals, 47001 women were allocated to the study group and offered repeated mammographic screening; 45933 were allocated to the control group. As compliance among women over 74 years of age was poor these were excluded from the present report. The yearly incidence of stage II or more advanced breast cancers after the initial screening round up to and including the second was reduced by 40 per cent in the study group compared with the controls. This effect was less marked in the age group 40-49. After 5.5 years average from the date of entry the absolute number of women with stage II-IV disease in the control group exceeded that for the study group by 44, whereas there was a large excess of cancer in situ and stage I cancer in the study group.

The factors, raising the risk of postoperative complications occurrence, are following: the primary tumor spreading, metastatic affection of lymphatic nodes of pelvic cavity, preoperative conduction of RTH or chemotherapy.

  7. Between Two Worlds: Liminality and Late-Stage Cancer-Directed Therapy.

    Science.gov (United States)

    Adorno, Gail

    2015-01-01

    Disease-directed therapy near death is a growing trend among persons living with late-stage cancer. As a sociocultural phenomenon, cancer-directed therapy (e.g., chemotherapy) when given for very advanced disease is a process that offers questionable benefits and portends further suffering, but also suggests potential for growth and transcendence. Theories and concepts drawn from cultural anthropology, sociology, and existentialism illustrate how contextual factors contribute to the creation of a "liminal space"; the latter part of the cancer trajectory where living and dying can overlap. When applied to clinical practice, this theoretical framework gives the patient, family, and health care provider a way of "unmasking" a period of transition during terminal illness when aggressive disease-directed care continues to be provided. The liminal space may function as an existential plane; a gateway or threshold with inherent potential for psychospiritual development during the final stage of life.

    Circulating microRNAs (miRNAs) have emerged as promising biomarkers; however, few miRNAs have been reproducible and can be used in clinical practice. In this study, we screened the levels of 754 miRNAs using TaqMan array in 50 individual plasma samples from 10 demographically matched healthy controls and 40 colorectal cancer (CRC) patients (10 each of stage I-IV) and identified 22 miRNAs associated with the presence of and stages of CRC. Then we performed the validation for 11 miRNAs in an independent cohort including 187 CRC cases and 47 healthy controls. Comprehensive analyses showed that plasma miR-96 distinguished stage I-IV CRC from healthy controls with an area under curve (AUC) of 0.740; miR-203 separated stage III-IV CRC patients from stage I-II with an AUC of 0.757; and miR-141 differentiated stage IV CRC from stage I-III patients with an AUC of 0.851. Survival analyses showed that plasma miR-96 and miR-200b were independent prognostic factors for overall survival. Thus, we propose four miRNAs (miR-96, miR-203, miR-141 and miR-200b) as clinically validated circulating biomarkers for CRC prognosis that warrant further evaluation for clinical utility.

    Full Text Available Background: Hepatocellular carcinoma (HCC is a common cancer in China, an area of high hepatitis B virus (HBV infection. Although several staging systems are available, there is no consensus on the best classification to use because multiple factors, such as etiology, clinical treatment and populations could affect the survival of HCC patients. Methods: This study analyzed 743 HBV-related Chinese HCC patients who received surgery first and evaluated the predictive values of eight different commonly used staging systems in the clinic. Results: The overall 1-, 3-, 5-year survival rates and a median survival were 91.5%, 70.3%, 55.3% and 72 months respectively. Barcelona Clinic Liver Cancer (BCLC staging systems had the best stratification ability and showed the lowest Akaike information criterion (AIC values (2896.577, followed by tumor-node-metastasis 7 th (TNM 7 th (AIC = 2899.980, TNM 6 th (AIC = 2902.17, Japan integrated staging score (AIC = 2918.085, Tokyo (AIC = 2938.822, Cancer of the Liver Italian Program score (AIC = 2941.950, Chinese University Prognostic Index grade (AIC = 2962.027, and Okuda (AIC = 2979.389. Conclusions: BCLC staging system is a better staging model for HBV infection patients with HCC in Chinese population among the eight currently used staging systems. These identifications afford a large group of Chinese HCC patients with HBV infection and could be helpful to design a new staging system for a certain population.

    These consensus guidelines on adjuvant radiotherapy for early-stage endometrial cancer were developed from an expert panel convened by the American College of Radiology. The American College of Radiology Appropriateness Criteria® are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method; and Grading of Recommendations Assessment, Development, and Evaluation, or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. After a review of the published literature, the panel voted on three variants to establish best practices for the utilization of imaging, radiotherapy, and chemotherapy after primary surgery for early-stage endometrial cancer.

    Background:Protein tyrosine kinase 6 (PTK6) is overexpressed in many epithelial tumors and predicts poor progno‑sis. However, PTK6 expression status and its role in cervical squamous cell cancer are unknown. This study aimed to investigate the expression level and clinical signiifcance of PTK6 in early‑stage cervical squamous cell cancer. Methods:Quantitative reverse transcription‑polymerase chain reaction (qRT‑PCR) and western blotting analysis were performed to detect PTK6 mRNA and protein expression levels in 10 freshly frozen, early‑stage cervical squamous cell cancer specimens and adjacent non‑tumorous cervical tissues. The expression of PTK6 was detected using immuno‑histochemical staining in 150 formalin‑ifxed, paraffn‑embedded, early‑stage cervical squamous cell cancer sections and 10 normal cervical tissue sections. Results:The mRNA and protein levels of PTK6 in cancer tissues were higher than those in adjacent non‑tumorous cervical tissues. Immunohistochemical analysis showed that PTK6 was not expressed in normal cervical tissues but was overexpressed in the cytoplasm of cervical squamous cell cancer cells. The level of PTK6 expression was signiif‑cantly associated with tumor grade (P=0.020). The 5‑year overall survival rate of patients with high PTK6 expression was lower than that of patients with low PTK6 expression (81.3% vs. 96.2%,P=0.008). Multivariate Cox regression analysis showed that the expression level of PTK6 in cervical squamous cell cancer was an independent prognostic factor for patient survival (hazard ratio=5.999, 95% conifdence interval 1.622–22.191,P Conclusions:PTK6 is overexpressed in cervical squamous cell cancer. Increased PTK6 expression is associated with reduced 5‑year overall survival. PTK6 expression is an independent prognostic predictor for cervical cancer.

    Background. Cervical carcinoma is the only gynecological tumor still being staged mainly by clinical examination and only a limited use of diagnostic radiology. Cross sectional imaging is increasingly used as an aid in the staging procedure. We wanted to assess the impact of magnetic resonance imaging (MRI) in addition to the clinical staging of patients with carcinoma of the uterine cervix. Material and methods. A retrospective single-centre analysis of 183 women referred to a tertiary referral centre for gynecological tumors (<= 65 years old) with cervical cancer diagnosed between January 1, 2003 and December 31, 2006 who have undergone an MRI investigation before start of treatment. Patient records were retrospectively reviewed and any change of the planned treatment after the MRI examination was noted. Results. In patients with cervical carcinoma FIGO stage Ia2-IIa treated surgically, the treatment plan was altered due to MRI results in 10/125 patients. In the smaller group of patients with clinically more advanced disease receiving radio-chemotherapy, the treatment plan was altered in 12/58 patients. Reasons for changing the treatment plan after MRI were findings indicating a higher (n = 8) or lower (n = 5) local tumor stage, findings of para aortic nodal disease (n = 4) or difficulty to clinically examine the patient due to obesity (n = 2). MRI was also an aid in deciding whether or not to offer fertility preserving treatment in three cases. Conclusion. The use of MRI affects treatment planning in patients with cancer of the uterine cervix. The impact is more obvious in more advanced stages of disease and in patients who are difficult to examine clinically due to, for example body constitution. The result of MRI is also an aid in deciding whether or not a fertility preserving operation is feasible

    2016-01-01

    Earlier detection and newer treatments now make breast cancer highly survivable, and breast cancer survivors are the largest female cancer survivor group in the United States. With earlier detection, more women are being diagnosed with early-stage breast cancer and need follow-up care. With the increasing number of breast cancer survivors, there is a projected shortage in the workforce of oncology specialists to care for these women. The American Society of Clinical Oncology recommends that breast cancer follow-up care can be provided by an oncologist or primary care provider, as long as the primary care provider has spoken to the oncologist about appropriate follow-up care. Several studies have shown that primary care providers and oncologists have comparable outcomes for follow-up care of women with early-stage breast cancer. The National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology (NCCN Guidelines) are considered the gold standard for breast cancer treatment and follow-up. These guidelines are clear and straightforward. Using knowledge of the NCCN Guidelines, primary care providers can fill the gap for follow-up care of women with early-stage breast cancer.

    Registry to follow 7372 women aged 30-60, who were in the labour force when diagnosed with breast cancer in 2000-06 and survived at least three years. Controls were 213,276 women without breast cancer. Inequalities in employment outlook were estimated as interaction effects in linear regression between...... educational attainment and disease on employment. RESULTS: There is significant interaction between education and breast cancer, but it is only marginally affected by including stage and comorbidity in the regression models. Education, breast cancer stage, and comorbidity all have strong effects on later...... employment, and a considerable amount of the educational effect is mediated by comorbidity and pre-cancer labour market participation and income. CONCLUSION: The result of the study is negative in the sense that the stronger effect of breast cancer on employment among low-educated compared to highly educated...

    2015-01-01

    Full Text Available Background: End-stage hypertrophic cardiomyopathy (HCM is complicated by substantial adverse events. However, few studies have focused on electrocardiographic features and their prognostic values in HCM. This study aimed to evaluate the clinical manifestations and prognostic value of electrocardiography in patients with end-stage HCM. Methods: End-stage HCM patients were enrolled from a total of 1844 consecutive HCM patients from April 2002 to November 2013 at Fuwai Hospital. Clinical data, including medical history, electrocardiography, and echocardiography, were analyzed. Cox hazards regression analysis was used to assess the risk factors for cardiovascular mortality. Results: End-stage HCM was identified in 99 (5.4% patients, averaged at 52 ± 16 years old at entry. Atrial fibrillation was observed in 53 patients and mural thrombus in 19 patients. During 3.9 ± 3.0 years of follow-up, embolic stroke, refractory heart failure, and death or transplantation were observed in 20, 39, and 51 patients, respectively. The incidence of annual mortality was 13.2%. Multivariate Cox hazards regression analysis identified New York Heart Association Class (NYHA III/IV at entry (hazard ratio [HR]: 1.99; 95% confidence interval [CI]: 1.05-3.80; P = 0.036, left bundle branch block (LBBB (HR: 2.80; 95% CI: 1.47-5.31; P = 0.002, and an abnormal Q wave (HR: 2.21; 95% CI: 1.16-4.23; P = 0.016 as independent predictors of cardiovascular death, in accordance with all-cause death and heart failure-related death. Conclusions: LBBB and an abnormal Q wave are risk factors of cardiovascular mortality in end-stage HCM and provide new evidence for early intervention. Susceptibility of end-stage HCM patients to mural thrombus and embolic events warrants further attention.

    Positron emission tomography (PET) and X-ray computed tomography (CT) serve as major diagnostic imaging modalities in the lung-cancer staging process. Modern scanners provide co-registered whole-body PET/CT studies, collected while the patient breathes freely, and high-resolution chest CT scans, collected under a brief patient breath hold. Unfortunately, no method exists for registering a PET/CT study into the space of a high-resolution chest CT scan. If this could be done, vital diagnostic information offered by the PET/CT study could be brought seamlessly into the procedure plan used during live cancer-staging bronchoscopy. We propose a method for the deformable registration of whole-body PET/CT data into the space of a high-resolution chest CT study. We then demonstrate its potential for procedure planning and subsequent use in multimodal image-guided bronchoscopy.

  2. Adoption of Hypofractionated Whole-Breast Irradiation for Early-Stage Breast Cancer: A National Cancer Data Base Analysis

    International Nuclear Information System (INIS)

    Purpose: To evaluate the relationship of patient, hospital, and cancer characteristics with the adoption of hypofractionation in a national sample of patients diagnosed with early-stage breast cancer. Methods and Materials: We performed a retrospective study of breast cancer patients in the National Cancer Data Base from 2004-2011 who were treated with radiation therapy and met eligibility criteria for hypofractionation. We used logistic regression to identify factors associated with receipt of hypofractionation (vs conventional fractionation). Results: We identified 13,271 women (11.7%) and 99,996 women (88.3%) with early-stage breast cancer who were treated with hypofractionation and conventional fractionation, respectively. The use of hypofractionation increased significantly, with 5.4% of patients receiving it in 2004 compared with 22.8% in 2011 (P<.001 for trend). Patients living ≥50 miles from the cancer reporting facility had increased odds of receiving hypofractionation (odds ratio 1.57 [95% confidence interval 1.44-1.72], P<.001). Adoption of hypofractionation was associated with treatment at an academic center (P<.001) and living in an area with high median income (P<.001). Hypofractionation was less likely to be used in patients with high-risk disease, such as increased tumor size (P<.001) or poorly differentiated histologic grade (P<.001). Conclusions: The use of hypofractionation is rising and is associated with increased travel distance and treatment at an academic center. Further adoption of hypofractionation may be tempered by both clinical and nonclinical concerns

    1433 transrectal ultrasonographies were performed for prostatic disease. In 453 cases, histopathologic correlation was obtained and compared to digital rectal examination and transrectal ultrasonography done after the clinical examination. The sensitivity of digital rectal examination was 91% and the specificity was 85%. The sensitivity and the specificity of ultrasonography were respectively 95 and 81%. 4 prostatic cancers, not suspected by digital rectal examination, were diagnosed by ultrasound (0,9%). The total number of subclinical cancer was 9 (2%). Interest of ultrasound compared to digital rectal examination concerns less than 1% of the total number of controlled patients. The staging of local extension of prostatic cancer is better by ultrasound than by the digital rectal examination. On 9 cases of clinical unsuspected extracapsular invasion, 6 were diagnosed by ultrasound.

    Full Text Available Vulvar cancer is a gynecological cancer whose incidence rate is relatively low. Patients generally were admitted at advanced stage, and radiation therapy at advanced stage does not provide favorable prognosis. Two main modalities in the treatment of vulvar cancer are surgery and radiation therapy. However, radiation can be performed in early stage vulvar cancer but surgery is thought to have more benefits, such as in side effect on the ovary/ reproductive function disorder, patient's hygiene factor, and the ease in performing therapy if recurrence occurs. There are various techniques of vulvar cancer surgery, such as radical vulvectomy with butterfly incision (RVBI and radical vulvectomy with separated incision (RVSI. The objective of this study was to identify the benefits of radical vulvectomy with separated incision in comparison with radical vulvectomy with butterfly incision in terms of the length of surgery, wound recovery, infection incidence, length of hospital stay. This study was a clinical trial performed during the period of 1990-2000. Fifteen cases of vulvar cancer were found and underwent surgery. Fourteen cases were at stage II and 14 cases were histologically defined as squamous-cell carcinoma and 1 case was adenocarcinoma. The average length of surgery in RVSI was 168 minutes, this was shorter than that in VRBI which reached an average of 275 minutes. The incidence of infection in RVSI group was 3 of 11 cases (27.27%, while in RVBI group all cases had infection in surgical wound. Failure of surgical wound approximation was 1 of 12 cases (9.99%, while in RVBI all cases experienced the failure such that cosmetic surgery was required. Length of postoperative care in RVSI group was 12.3 days, while in RVBI 21.5 days. Thus, complications in VRBI were lower, and length of surgery and length of postoperative care were shorter.

    AIM: To investigate the value of transabdominal ultrasonography (US) in the preoperative staging of gastric cancer.METHODS: A total of 198 patients with gastric cancer underwent preoperatively transabdominal US, depth of tumor infiltration was assessed in 125 patients, and lymph node metastasis was assessed in 106 patients.RESULTS: The staging accuracy of transabdominal US was 55.6%, 75.0%, 87.3% and 71.1% in T1, T2, T3 and T4 carcinomas, respectively. The overall accuracy was 77.6%.The detection rate for pancreatic invasion and liver invasion was 77.4%, 71.4%, respectively. The sensitivity, specificity,accuracy of transabdominal US in assessment of lymph node metastasis were 77.6%, 64.1%, 72.6%, respectively.Various shapes such as round, ovoid, spindle were encountered in benign and malignant lymph nodes. Majority of both benign and malignant lymph nodes were hyperechoic and had a distinct border. Benign lymph nodes were smaller than malignant lymph nodes in length and width (P = 0.000,0.005). Irregular shape, fusional shape, infiltrative signs,inhomogenous echo were seen mainly in malignant lymph nodes (P = 0.045, 0.006, 0.027, 0.006).CONCLUSION: Transabdominal US is useful for preoperative staging in gastric cancer, although it is difficult to differentiate benign from malignant lymph nodes.

The widespread use of the recently introduced multi-detector CT scanners has resulted in an increasing number of incidentally diagnosed pulmonary embolism (PE in asymptomatic cancer patients. The significance and clinical outcome of such incidental PE is described.Methods: Both radiology department and hospital databases were searched for all cancer patients with a diagnosis of incidental PE. CT scans were performed using a 64-slice scanner with a 5.0 mm slice thickness.Results: During the study period, 34 patients with incidental PE were identified. The mean age (±SD was 57.7 (±12.4 years. All patients had active cancer, gastric, lung, colorectal, and lymphomas being the most frequent. Most patients had advanced-stage disease at the time of PE diagnosis; 26 (77% patients had stage IV, whereas only 3 patients had stages I or II disease. Twenty-seven (79% patients had their PE while undergoing active treatment with chemotherapy (68% or radiotherapy (12%; none, however, were on hormonal therapy. Most (74% patients had their PE diagnosed without history of recent hospital admission. Except for 5 (15%, all other patients were anticoagulated. With follow-up, 2 patients developed recurrent PE, 2 others had clinical and echocardiographic evidence of pulmonary hypertension, and 9 (26% died suddenly within 30 days of the diagnosis of incidental PE; 2 of these where among the 5 patients who were not anticoagulated.Conclusion: Incidental PE in cancer patients is increasingly encountered. Similar to symptomatic PE, many were diagnosed in patients with advanced stage disease and while undergoing active anti-cancer therapy. A significant percentage of patients had recurrent emboli, pulmonary hypertension

    Clinical trials of late-stage breast cancer patients and late-stage melanoma patients treated by laser immunotherapy (LIT) have shown promising results. In a 2010 study of Li et al, eleven late-stage melanoma patients received LIT in one or multiple 6-week treatment cycles applied to a 200-cm2 treatment site, which usually contained multiple cutaneous metastases. Long-term, positive response was observed in six patients. All lesions in the treatment area of the patients responded to LIT, eight of which achieved complete local response (CLR). CLR was observed in the non-treatment site (regional) lesions in four patients. Five patients were still alive at the time of last follow-up. The probability of 12-month overall survival was 70%.2 In 2011, Li et al, treated ten late stage breast cancer patients with LIT.1 In 8 patients available for evaluation, the objective response rate was 62.5% and the clinical beneficial response rate was 75%.1 This review demonstrates that LIT is safe and well tolerated, so it can be easily applied on an outpatient basis and can be combined with other pharmaceutical modalities to improve the therapeutic response of metastatic cancers.

    Background in our previous studies, we found the expression of 14-kD phosphohistidine phosphatase (PHPT1) was associated with lung cancer cells migration and invasion, and PHPT1 mRNA expression level in lung cancer tissues clinically correlated with lymph node metastasis. in the present study, we aimed to further investigate the expression of PHPT1 protein in lung cancer.Methods Expression of PHPT1 protein in tissue samples from 146 lung cancers and 30 normal tissues adjacent to lung cancers was assessed using immunohistochemical method. Fisher's exact test was used to analyze expression patterns of PHPT1 protein in these tissue types. Meanwhile, we studied the correlation between expression of PHPT1 protein and clinicopathological features in lung cancer.Results Significantly higher expression levels of PHPT1 protein were found in lung cancer samples (53.42%) than in normal tissues adjacent to lung cancer (23.33%) (P=0.003). Fisher's exact test showed that lung cancer stage positively correlated with expression of PHPT1 protein (P=0.02), and lung cancer samples with lymph node metastasis showed higher PHPT1 protein expression (P=0.016) than the samples without lymph node metastasis.Conclusions The results of this study agree with findings from our previous study of PHPT1 mRNA expression in lung cancer tissues, and strongly suggest that PHPT1 protein is closely associated with the carcinogenesis and metastasis of lung cancer. Thus, therapy targeting PHPT1 (inhibition or silencing) could be potentially benefited for lung cancer patients.

    A prospective study was undertaken to determine the reproducibility of clinical staging based on digital rectal examination (DRE) in prostate carcinoma. We evaluated 48 consecutive patients diagnosed with localized prostatic cancer. Four urologists performed DRE and sorted the patients according to the 1992 American Joint Committee on Cancer Classification for prostate cancer. Both the percentage observed total agreement among each couple of two different observers and the interobserver variability (Kappa index) were analyzed. The percentage observed total agreement among observers in distinguishing five clinical subcategories (T1c, T2a, T2b, T2c, and T3a) ranged between 38-60% (mean 49%) and the Kappa index showed interobserver agreement was poor (overall Kappa = 0.3 1). All four examiners agreed in assigning the same subcategory in only 21 % of cases, and 90% of them were T I. If only categories are distinguished (T I, T2, or T3), the percentage observed total agreement rises to 60-71% (mean 66%) and the interexaminer agreement improves to good (overall Kappa = 0.4 1). Accurate pathologic staging was obtained in every patient and the percentage observed agreement between every examiner and the pathologist was calculated, excluding cases interpreted as T I c. Regarding subcategories, clinicopathologic agreement ranges between 17-46%. If only categories T2 and9T3 are distinguished, agreement rises to 57-69%. In summary, the ability to reproduce clinical staging based on DRE among multiple examiners is disappointingly low and understandably correlates poorly with pathologic stage.

    2012-06-01

    Prostate cancer is the most common non-skin cancer in men. It is fraught with both physical and psychological symptomatology. Depression, anxiety, stress, fatigue, pain and psychosocial factors all affect the patient with prostate cancer. Impotence, erectile dysfunction, sexual issues and incontinence in these patients complicate matters further. Anxiety may exist both before testing and while awaiting test results. Confusion over choosing from various interventions often adds to anxiety and depression in these patients. Various demographic factors and the developmental stage of the couple affect these psychological symptoms. The caregiver may undergo significant psychological turmoil while caring for a patient diagnosed with prostate cancer, which is addressed. The role of nurses in the management of prostate cancer is discussed. The present review looks at psychological issues in patients with prostate cancer from a clinical perspective, with the aim of highlighting these issues for the clinical urologist dealing with these patients. It also explores the consultation-liaison relationship between psychiatrists, psychologists and urologists as a team for the multimodal management of prostate cancer. PMID:22212706

  1. A clinical analysis of cases with stage IV laryngeal carcinoma

    International Nuclear Information System (INIS)

    Forty-four cases with stage IV laryngeal carcinoma treated in our department between 1991 and 2009 were clinically analyzed. The cases were equivalent to 16.8% of the total laryngeal cases, and 77.3% of the stage IV cases were of the supraglottic type. The disease-specific 5-year survival rate of all of the stage IV cases was 67.2%. Differences in the prognoses between under T3 and T4 were not statistically significant. Although the differences in the prognoses between surgical and nonsurgical treatment of the larynx were not statistically significant, neck dissection cases had a significantly better prognosis compared to cases without neck dissection. Neither radiotherapy nor chemotherapy had any influence on the prognosis. Therefore, positive treatment is needed even though the stage of the cases is advanced, and especially in cases with neck lymph node metastasis, neck dissection is strongly recommended. For histopathologically high-risk cases in which radiotherapy and chemotherapy were indicated in this study, appropriate additional treatment will be effective in order to prevent prognostic deterioration.

  2. The development and validation of oral cancer staging using administrative health data

    International Nuclear Information System (INIS)

    Oral cancer is a major global health problem. The complexity of histological prognosticators in oral cancer makes it difficult to compare the benefits of different treatment regimens. The Taiwanese National Health database provides an opportunity to assess correlations between outcome and treatment protocols and to compare the effects of different treatment regimens. However, the absence of indices of disease severity is a critical problem. The aim of this study was to ascertain how accurately we could assess the severity of oral cancer at the time of initial diagnosis on the basis of variables in a national database. In the cancer registry database of a medical center in Taiwan, we identified 1067 histologically confirmed cases of oral cancer (ICD9 codes 140, 141 and 143–145) that had been first diagnosed and subjected to initial treatment in this hospital. The clinical staging status was considered as the gold standard and we used concordance (C)-statistics to assess the model’s predictive performance. We added the predictors of treatment modality, cancer subsite, and age group to our models. Our final overall model included treatment regimen, site, age, and two interaction terms; namely, interactions between treatment regimen and age and those between treatment regimen, site, and age. In this model, the C-statistics were 0.82–0.84 in male subjects and 0.96–0.99 in female subjects. Of the models stratified by age, the model that considered treatment regimen and site had the highest C-statistics for the interaction term, this value being greater than 0.80 in male subjects and 0.9 in female subjects. In this study, we found that adjusting for sex, age at first diagnosis, oral cancer subsite, and therapy regimen provided the best indicator of severity of oral cancer. Our findings provide a method for assessing cancer severity when information about staging is not available from a national health-related database

    Breast cancer is the malignant neoplasia with the highest incidence in women worldwide. Chronic oxidative stress and inflammation have been indicated as major mediators during carcinogenesis and cancer progression. Human studies have not considered the complexity of tumor biology during the stages of cancer advance, limiting their clinical application. The purpose of this study was to characterize systemic oxidative stress and immune response parameters in early (ED; TNM I and II) and advanced disease (AD; TNM III and IV) of patients diagnosed with infiltrative ductal carcinoma breast cancer. Oxidative stress parameters were evaluated by plasmatic lipoperoxidation, carbonyl content, thiobarbituric reactive substances (TBARS), nitric oxide levels (NO), total radical antioxidant parameter (TRAP), superoxide dismutase, and catalase activities and GSH levels. Immune evaluation was determined by TNF-α, IL-1β, IL-12, and IL-10 levels and leukocytes oxidative burst evaluation by chemiluminescence. Tissue damage analysis included heart (total CK and CKMB), liver (AST, ALT, GGT), and renal (creatinine, urea, and uric acid) plasmatic markers. C-reactive protein (CRP) and iron metabolism were also evaluated. Analysis of the results verified different oxidative stress statuses occur at distinct cancer stages. ED was characterized by reduction in catalase, 8-isoprostanes, and GSH levels, with enhanced lipid peroxidation and TBARS levels. AD exhibited more pronounced oxidative status, with reduction in catalase activity and TRAP, intense lipid peroxidation and high levels of NO, TBARs, and carbonyl content. ED patients presented a Th2 immune pattern, while AD exhibited Th1 status. CRP levels and ferritin were increased in both stages of disease. Leukocytes burst impairment was observed in both the groups. Plasma iron levels were significantly elevated in AD. The data obtained indicated that oxidative stress enhancement and immune response impairment may be necessary to ensure

    Full Text Available Tabitha Y Chan, Poh Wee Tan, Johann I Tang Department of Radiation Oncology, National University Cancer Institute, Singapore Abstract: Proton-beam therapy (PBT for prostate cancer has been in used for several decades, with its technique evolving significantly over this period. A growing number of centers now routinely utilize pencil-beam scanning as an advanced technique of PBT. Interest and controversy concerning its use have recently come under scrutiny. While the past decade has produced an assemblage of evidence suggesting that PBT is safe and effective for early stage prostate cancer, it is still unknown whether the theoretical dosimetric advantages of PBT translate into meaningful clinical improvements over routine intensity-modulated radiation therapy, which is commonly used for these patients. Outcomes from early trials using whole courses of PBT have shown mixed results when compared with routine intensity-modulated radiation therapy. Therefore, randomized trials comparing these two techniques should be undertaken, as this would help in defining the role of PBT for this patient group. This article aims to describe the basics of PBT, review the reasons for the growing interest in PBT, review the evidence for PBT, review the controversy surrounding PBT, and inquire about PBT’s future in the treatment of prostate cancer, with attention to its physical properties, comparative clinical and cost-effectiveness, and advances in its delivery.

    2016-10-01

    Sarcopenia has been associated with several negative clinical outcomes in cancer. However, the consequences of sarcopenic obesity, a condition of combined sarcopenia and obesity burden, have been less extensively investigated. The aim of this paper was to review the current evidence on the prevalence and clinical implications of sarcopenic obesity in cancer. A total of 14 studies linking sarcopenic obesity to a clinical outcome in cancer were included. There is considerable inconsistency in methods used to evaluate body composition as well as in the criteria used to define sarcopenic obesity, which limits comparison among studies. Therefore, the prevalence of sarcopenic obesity varied substantially: between 1 and 29 % in studies including individuals from all body mass index categories and between 15 and 36 % for those including obese individuals only. Negative clinical outcomes reported to be associated with sarcopenic obesity included higher risk of dose-limiting toxicity, surgical complications, physical disability, and shorter survival.

    AIM: The aim of the present study is to use immunohistochemical methods to investigate the clinical implications of tumor markers in esophageal squamous cell carcinoma and evaluate their impact on prognosis.METHODS: From November 1990 to December 1996, 47patients were treated with preoperative radiation followed by radical esophagectomy. All patients were confirmed pathologically as suffering from squamous cell carcinoma.Immunohistochemical stain was done for PCNA, cyclinD1 protein expression and DNA content analyzed by image cytometry. Kaplan-Meier method for single prognostic factor and log-rank test was used to test the significant difference. Cox stepwise regression model and prognosis index model were used for survival analysis with multiple prognostic factors.RESULTS: Radio-pathological change, T stage and N stage, as the traditional prognostic factors had statistical difference in 3-, 5- and 10-year survival rates. While, tumor cell proliferating marked PCNA, cyclinD1 and DNA content served as independent prognostic factors of esophageal carcinoma. There was definitely an identity between the single and multiple factor analyses. PI was more accurate to evaluate the prognosis of esophageal carcinoma.CONCLUSION: It is possible that tumor cell proliferating marked PCNA, cyclinD1 and DNA content would become the endpoints for evaluating the prognosis of esophageal carcinoma.

    OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage II breast cancer.METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage II, during the period of 1995 to 2001, were analyzed retrospectively. Among the patients, 47 were treated with neoadjuvant chemotherapy, and 66 received no adjuvant therapy before surgery (control group). After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen, the surgical procedure was conducted.RESULTS Complete remission (CR) was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission (PR) was reached for 22 cases. The rate of breast-conserving surgery was enhanced from 22.73% to 46.81% (P<0.05) in the neoadjuvant treatment group. There was no difference in the 5-year overall survival (OS) and disease-free survival (DFS) rate between the two groups (P>0.05), but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group (P<0.05).CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage II breast cancer and may improve the prognosis of the cases with clinical remission.

    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.

    2015-01-01

    Full Text Available Objective: Although Helicobacter pylori (H. pylori is considered as the main etiological factor for gastric cancer, the strategy of screening and treating the oncogenic bacterium is still controversial. The objective was to evaluate the status and progress of the cognition about the relationship between H. pylori infection and gastric cancer from a clinical aspect. Data Sources: The data used in this review were mainly from the PubMed articles published in English from 1984 to 2015. Study Selection: Clinical research articles were selected mainly according to their level of relevance to this topic. Results: Gastric cancer is the fifth most common malignancy and the third leading cause of cancer deaths worldwide. The main etiological factor for gastric cancer is H. pylori infection. About 74.7-89.0% gastric cancer was related to H. pylori infection. Up to date, some regional gastric cancer prevention programs including the detection and treatment of H. pylori infection are under way. Current data obtained from the randomized controlled trials suggest that population-based H. pylori screening and treatment is feasible and cost-effective in preventing gastric cancer; however, a population-based H. pylori eradication campaign would potentially lead to bacterial resistance to the corresponding antibiotics, as well as a negative impact on the normal flora. Conclusions: The important questions of feasibility, program costs, appropriate target groups for intervention, and the potential harm of mass therapy with antibiotics must first be answered before implementing any large-scale program.

  14. Multidisciplinary management of stage III breast cancer: chemotherapy, surgery and radiotherapy

    International Nuclear Information System (INIS)

    A prospective study, in which women with clinically stage III breast cancer underwent multidisciplinary therapy by using primary (neoadjuvant) chemotherapy, followed randomly by loco-regionally therapy, either with surgery or radiotherapy; and postoperative systemic chemotherapy, in both groups of treatment, was conduced at the Peruvian Institute of Neoplasic Diseases. This is a randomized, prospective, descriptive, interventionist and analytical clinical study. Clinical response to primary chemotherapy was positive in 80,23% of cases, complete resolution was observed in 18,60% of cases, partial resolution in 61,63% of cases and there was absolutely no response in 19,77% of cases. No residual neoplasm, pathologically proven, was observed in 8,33% of surgical cases. We demonstrated that high-dose primary chemotherapy, using only 2 drugs (cyclophosphamide and 5-fluorouracil), used here because of its lower price, brought similar results compared to anthracycline-containing regimens. Recurrence rates were similar and showed no significative differences in both groups of treatment. Both, the disease-free survival (DFS) and overall survival (OS), were similar in both groups of treatment. We also demonstrated that in patients who underwent surgery, the lower the number of axillary lymph node metastases, the higher the overall survival (OS) time. Patients with clinically stage III (A or B) breast cancer, showed similar clinical responses to neoadjuvant chemotherapy, they also showed similar recurrence rates, DFS and OS, when treated with radical mastectomy or radiotherapy.

    Greater understanding of the biology and epidemiology of prostate cancer in the last several decades have led to significant advances in its management.Prostate cancer is now detected in greater numbers at lower stages of disease and is amenable to multiple forms of efficacious treatment.However,there is a lack of conclusive data demonstrating a definitive mortality benefit from this earlier diagnosis and treatment of prostate cancer.It is likely due to the treatment of a large proportion of indolent cancers that would have had little adverse impact on health or lifespan if left alone.Due to this overtreatment phenomenon,active surveillance with delayed intervention is gaining traction as a viable management approach in contemporary practice.The ability to distinguish clinically insignificant cancers from those with a high risk of progression and/or lethality is critical to the appropriate selection of patients for surveillance protocols versus immediate intervention.This chapter will review the ability of various prediction models,including risk groupings and nomograms,to predict indolent disease and determine their role in the contemporary management of clinically localized prostate cancer.

    Lung cancer, the leading cause of cancer-related death, still lacks reliable biomarkers. Apurinic/apyrimidinic endonuclease 1/Ref-1 is a multifunctional protein involved in the base excision repair of DNA damaged by oxidative stress or alkylating compounds, as well as in the regulation of multiple transcription factors. To validate apurinic/apyrimidinic endonuclease 1/Ref-1 as a biomarker for prediction of lung cancer recurrence, we studied 42 patients who received curative resection and mediastinal lymph node dissection for stage I non-small-cell lung cancer. They were divided into 2 groups based on recurrence, and compared by immunohistochemistry staining of paraffin-embedded tissues and Western blot analysis. Immunohistochemical staining showed a significant difference between the cytoplasm and nucleus in patients who had a recurrence compared to those with nonrecurrent adenocarcinoma. In Western blot analysis, the recurrent adenocarcinoma group showed increased expression of apurinic/apyrimidinic endonuclease 1/Ref-1 in cytoplasm, nucleus, and in total. This indicates that apurinic/apyrimidinic endonuclease 1/Ref-1 is unregulated in recurrent stage I adenocarcinoma. For clinical application as a prognostic marker for non-small-cell lung cancer, further investigation into the role of apurinic/apyrimidinic endonuclease 1/Ref-1 in carcinogenesis is needed in an expanded prospective study.

    Objective. To examine the association between metformin use and cancer stage at diagnosis among elderly men with preexisting diabetes mellitus and incident prostate cancer. Methods. This study used a population-based observational cohort of elderly men (≥66 years) with preexisting diabetes and incident prostate cancer between 2008 and 2009 (N = 2,652). Cancer stage at diagnosis (localized versus advanced) was based on the American Joint Cancer Committee classification. Metformin use and other independent variables were measured during the one year before cancer diagnosis. Logistic regressions with inverse probability treatment weights were used to control for the observed selection bias. Results. A significantly lower percentage of metformin users were diagnosed with advanced prostate cancer as compared to nonusers (4.7% versus 6.7%, p metformin use was associated with a 32% reduction in the risk of advanced prostate cancer (adjusted odds ratio, AOR: 0.68, 95% confidence interval, CI: 0.48, 0.97). Conclusions. This is the first epidemiological study to support the role of metformin in reducing the risk of advanced prostate cancer. Randomized clinical trials are needed to confirm the causal link between metformin use and prostate cancer diagnosis stage. PMID:27547763

The discovery and clinical evaluation of novel specific and robust non-invasive biomarkers for diagnosis of lung cancer at an early stage, as well as for better prognosis and prediction of therapy response, is very challenging. MicroRNAs (miRNAs can play an important role in the diagnosis and management of lung cancer patients, as important and reliable biomarkers for cancer detection and prognostic prediction, and even as promising as novel targets for cancer therapy. miRNAs are important in cancer pathogenesis, and deregulation of their expression levels has been detected not only in lung cancer but in many other human tumor types. Numerous studies strongly support the potential of miRNAs as biomarkers in non-small-cell lung cancer, and there is increasing evidence that altered miRNA expression is associated with tumor progression and survival. It is worth mentioning also that detection of miRNAs circulating in plasma or serum has enormous potential, because miRNAs serve as non-invasive biomarkers not only for the diagnosis and prognosis of the disease, but also as novel response and sensitivity predictors for cancer treatment. In this review, we summarize the current findings on the critical role of miRNAs in lung cancer tumorigenesis and highlight their potential as circulating biomarkers in lung cancer. Our review is based on papers that have been published after 2011, and includes the key words “miRNAs” and “lung cancer”.

  3. Dynamic FDG PET in characterizing and staging lung cancer

    International Nuclear Information System (INIS)

    CT has proven inadequate for staging lung cancer. This study evaluates F-18 deoxyglucose (FDG) positron emission tomography (PET) in assessing mediastinal metastases of lung tumors, differentiating benign from malignant parenchymal masses, and complementing radiographic and laboratory findings in lymphoma. The authors of this paper examined 13 patients with pulmonary masses as determined by chest radiographs and CT scans. PET scans were obtained with 255.3-592 MBq FDG scanned in dynamic mode at 5 minutes per frame for 45 minutes and one 15 minutes per frame. Image analysis included visual inspection, time activity curves (TAC), and calculation of differential uptake ratio (DUR) in regions of interest versus normal tissue

    Background Neoadjuvant chemotherapy has been used as a primary treatment for locally advanced or inflammatory breast cancer, and recently extended to operable breast cancer. However, only a few studies have published data concerning the outcomes of patients with stages Ⅱ and Ⅲ breast cancer after neoadjuvant chemotherapy. Methods This study retrospectively investigated the clinical value of neoadjuvant chemotherapy for patients with stages Ⅱ and Ⅲ breast cancer. The patients in Group 1 (n=54) were treated with neoadjuvant chemotherapy, followed by definitive surgery and adjuvant therapy. The patients in Group 2 (n=43) initially received definitive surgery, followed by adjuvant chemotherapy and other therapies. The operability rates for breast conservation and dermatoplasty were observed in Group 1 after neoadjuvant chemotherapy. After follow-up, the recurrence and overall and disease-free survival rates of the two groups were analyzed.Results Neoadjuvant chemotherapy increased the operability rates for breast conservation from 17.1% to 40.0% in stage Ⅱ (P=0.034) and 0% to 12.6% in stage Ⅲ (P=0.016), and decreased the dermatoplasty rates from 17.1% to 2.8% in stage Ⅱ (P=0.046) and 28.1% to 8.1% in stage Ⅲ (P=0.026). After a median follow-up of 46.8 months, there were 11 deaths and 13 recurrences in Group 1, and 15 deaths and 19 recurrences in Group 2. The overall and disease-free survival rates of stage Ⅲ disease were significantly higher in Group 1 than in Group 2 (68.4% vs 31.2%, P=0.028, and 63.2% vs 25.0%, P=0.024, respectively). There were no significant differences in the overall and disease-free survival rates of stage Ⅱ disease for Group 1 compared with Group 2 (85.7% vs 85.2%, P=0.953, and 80.6% vs 74.1%, P=0.400, respectively).Conclusions Neoadjuvant chemotherapy resulted in increased operability for breast conservation and decreased dermatoplasty. Neoadjuvant chemotherapy exhibited better recurrence control, and overall and disease

    How to use CT and PET-CT rationally to raise diagnosis, staging and prognostic assessment of lung cancer to a higher level at the best cost-effect ratio is a subject that Chinese clinicians and radiologists should face conscientiously. We review the rational application of CT and PET-CT in four aspects of lung cancer, including screening and detection, morphologic evaluation, haemodynamic or metabolic feature evaluation, and follow-up, staging and prognostic evaluation. As PET-CT is only available in class III-A hospitals today, CT is the most popular equipment in China. PET-CT is more valuable only in cases where CT presentation of lung cancer is atypical or difficult to determine, or in cases where the diagnosis of lung cancer has been initially confirmed, for which clinical staging and decision concerning on therapeutic regimens are needed. We also recommend the current strategies of CT and PET-CT managing of SPN in China. (orig.)

    Full Text Available Complete response (CR rates reported for cytotoxic chemotherapy for late-stage cancer patients are generally low, with few exceptions, regardless of the solid cancer type or drug regimen. We investigated CR rates reported in the literature for clinical trials using chemotherapy alone, across a wide range of tumour types and chemotherapeutic regimens, to determine an overall CR rate for late-stage cancers. A total of 141 reports were located using the PubMed database. A meta-analysis was performed of reported CR from 68 chemotherapy trials (total 2732 patients using standard agents across late-stage solid cancers—a binomial model with random effects was adopted. Mean CR rates were compared for different cancer types, and for chemotherapeutic agents with different mechanisms of action, using a logistic regression. Our results showed that the CR rates for chemotherapy treatment of late-stage cancer were generally low at 7.4%, regardless of the cancer type or drug regimen used. We found no evidence that CR rates differed between different chemotherapy drug types, but amongst different cancer types small CR differences were evident, although none exceeded a mean CR rate of 11%. This remarkable concordance of CR rates regardless of cancer or therapy type remains currently unexplained, and motivates further investigation.

    Full Text Available Normal cells have a level of epigenetic programming that is superimposed on the genetic code to establish and maintain their cell identity and phenotypes. This epigenetic programming can be thought as the architecture, a sort of cityscape, that is built upon the underlying genetic landscape. The epigenetic programming is encoded by a complex set of chemical marks on DNA, on histone proteins in nucleosomes, and by numerous context-specific DNA, RNA, protein interactions that all regulate the structure, organization, and function of the genome in a given cell. It is becoming increasingly evident that abnormalities in both the genetic landscape and epigenetic cityscape can cooperate to drive carcinogenesis and disease progression. Large-scale cancer genome sequencing studies have revealed that mutations in genes encoding the enzymatic machinery for shaping the epigenetic cityscape are among the most common mutations observed in human cancers, including prostate cancer. Interestingly, although the constellation of genetic mutations in a given cancer can be quite heterogeneous from person to person, there are numerous epigenetic alterations that appear to be highly recurrent, and nearly universal in a given cancer type, including in prostate cancer. The highly recurrent nature of these alterations can be exploited for development of biomarkers for cancer detection and risk stratification and as targets for therapeutic intervention. Here, we explore the basic principles of epigenetic processes in normal cells and prostate cancer cells and discuss the potential clinical implications with regards to prostate cancer biomarker development and therapy.

  10. Clinical studies of lung cancer of atomic bomb survivors, 4

    International Nuclear Information System (INIS)

    A comparative study was made on complications of lung cancer in 188 A-bomb survivors (group 1) and 327 non-exposed patients (group 2) treated from 1972 through 1982. The incidence of complications was higher in group 1 (32 %) than in group 2 (20 %). Complications occurred most frequently in the respiratory system, followed by those in the circulatory system and diabetes mellitus in both groups. Patients with complications in the respiratory, circulatory, or nervous system tended to be inoperable. For patients with clinical stage I or II developing complications, the prognosis was worse as compared with those without complications. Long-term survival can be achieved in two patients with early stage lung cancer in whom surgical treatment was impossible because of the association of severe complications. (Namekawa, K.)

    Full Text Available The role of PPARγ in adipocyte differentiation has fueled intense interest in the function of this steroid nuclear receptor for regulation of malignant cell growth and differentiation. Given the antiproliferative and differentiating effects of PPARγ ligands on liposarcoma cells, investigation of PPARγ expression and ligand activation in other solid tumors such as breast, colon, and prostate cancers ensued. The anticancer effects of PPARγ ligands in cell culture and rodent models of a multitude of tumor types suggest broad applicability of these agents to cancer therapy. This review focuses on the clinical use of PPARγ ligands, specifically the thiazolidinediones, for the treatment and prevention of cancer.

    Objective:The purpose of the study was to study the mechanism of vasculogenic mimicry (VM) and its relation-ship with tumor stage in non-smal celllung cancer (NSCLC). Methods:Forty-two patients with NSCLC were col ected, 19 belonged to the early stage (stages I+II) while 23 were late stage (stages III+IV). Moreover, 20 patients got surgical treat-ment and 22 got chemotherapy. We studied the relationship of VM with stage, chemotherapeutic ef ect, HIF-1α, microves-sel density (MVD) and clinicopathologic features. Results:VM in patients of early stages were significantly more than late stages (68.4%vs 26.1%, P=0.006), and the positive rate of VM was proportional to HIF-1α(P=0.034). But no correlation was found between VM and chemotherapeutic ef ect (14.3%vs 26.7%, P=1.00) or MVD (P>0.05). Furthermore, we found VM also showed a negative correlation with distant metastases and lymph nodes metastases (P<0.05) while no correlation was found with other clinicopathologic. Conclusion:VM was generated during the early stage in NSCLC and correlated with lymph nodes metastases. As the disease progressed, VM may be replaced by vascular endothelial cells, so the late-stage patients especial y people with distant metastases had fewer VM. As the main factor produced by hypoxia, HIF-1αmay make a dif erence in VM formation. Thus we inferred VM might be a new target for targeted therapy, and could provide help for clinical staging and treatment.

    Full Text Available Abstract Background Hypermethylation of promoter CpG islands with associated loss of gene expression, and hypomethylation of CpG-rich repetitive elements that may destabilize the genome are common events in most, if not all, epithelial cancers. Methods The methylation of 6,502 CpG-rich sequences spanning the genome was analyzed in 137 ovarian samples (ten normal, 23 low malignant potential, 18 stage I, 16 stage II, 54 stage III, and 16 stage IV ranging from normal tissue through to stage IV cancer using a sequence-validated human CpG island microarray. The microarray contained 5' promoter-associated CpG islands as well as CpG-rich satellite and Alu repetitive elements. Results Results showed a progressive de-evolution of normal CpG methylation patterns with disease progression; 659 CpG islands showed significant loss or gain of methylation. Satellite and Alu sequences were primarily associated with loss of methylation, while promoter CpG islands composed the majority of sequences with gains in methylation. Since the majority of ovarian tumors are late stage when diagnosed, we tested whether DNA methylation profiles could differentiate between normal and low malignant potential (LMP compared to stage III ovarian samples. We developed a class predictor consisting of three CpG-rich sequences that was 100% sensitive and 89% specific when used to predict an independent set of normal and LMP samples versus stage III samples. Bisulfite sequencing confirmed the NKX-2-3 promoter CpG island was hypermethylated with disease progression. In addition, 5-aza-2'-deoxycytidine treatment of the ES2 and OVCAR ovarian cancer cell lines re-expressed NKX-2-3. Finally, we merged our CpG methylation results with previously published ovarian expression microarray data and identified correlated expression changes. Conclusion Our results show that changes in CpG methylation are cumulative with ovarian cancer progression in a sequence-type dependent manner, and that Cp

    Objective: to study the clinical significance of Pglycoprotein (P-gp) in breast cancer. Methods: Expression of P-gp in 60 cases of breast cancer was examined by immunohistochemistry. P-gp expression and response to chemotherapy were comparatively investigated in 19 patients with metastatic breast cancer. Results: The P-gp was positive in 48.3% of the 60 cases of breast cancer. P-gp expression was not related to patients' age, menstruation status, number of axillary lymph nodes involved, clinical stage, histological type, and hormonal receptor status (P>0.05). The frequency of metastasis (62.1%) and mortality (51.7%) were higher in P-gp positive cases than in negative cases (16.1% vs 12.9%, P<0.005). The 5-year survival rate of P-gp positive cases (48.3%) was significantly lower than that of negative cases (87.1%) (P<0.05). In patients who received adjuvant chemotherapy distant metastasis occurred more frequently in the P-gp positive cases (94.7%) than in the P-gp negative cases (57.1%) (P=0.0468). More P-gp negative patients (7/9) than positive patients (1/10) were responsive to chemotherapy (P=0.0055).Conclusion: Immunohistochemical examination of P-gp expression is useful in predicting response to chemotherapy and prognosis in breast cancer patients. P-gp positivity is associated with poor prognosis.

    The main goal of 2-stage liver transplant is to provide time to obtain a new liver source. We describe our experience of 3 patients with 3 different clinical conditions. A 57-year-old man was retransplanted successfully with this technique due to hepatic artery thrombosis. However, a 38-year-old woman with fulminant toxic hepatitis and a 5-year-old-boy with abdominal trauma had poor outcome. This technique could serve as a rescue therapy for liver transplant patients who have toxic liver syndrome or abdominal trauma. These patients required intensive support during long anhepatic states. The transplant team should decide early whether to use this technique before irreversible conditions develop. PMID:25894175

  3. A germline mutation in the BRCA1 3’UTR predicts Stage IV breast cancer

    International Nuclear Information System (INIS)

    A germline, variant in the BRCA1 3’UTR (rs8176318) was previously shown to predict breast and ovarian cancer risk in women from high-risk families, as well as increased risk of triple negative breast cancer. Here, we tested the hypothesis that this variant predicts tumor biology, like other 3’UTR mutations in cancer. The impact of the BRCA1-3’UTR-variant on BRCA1 gene expression, and altered response to external stimuli was tested in vitro using a luciferase reporter assay. Gene expression was further tested in vivo by immunoflourescence staining on breast tumor tissue, comparing triple negative patient samples with the variant (TG or TT) or non-variant (GG) BRCA1 3’UTR. To determine the significance of the variant on clinically relevant endpoints, a comprehensive collection of West-Irish breast cancer patients were tested for the variant. Finally, an association of the variant with breast screening clinical phenotypes was evaluated using a cohort of women from the High Risk Breast Program at the University of Vermont. Luciferase reporters with the BRCA1-3’UTR-variant (T allele) displayed significantly lower gene expression, as well as altered response to external hormonal stimuli, compared to the non-variant 3’UTR (G allele) in breast cancer cell lines. This was confirmed clinically by the finding of reduced BRCA1 gene expression in triple negative samples from patients carrying the homozygous TT variant, compared to non-variant patients. The BRCA1-3’UTR-variant (TG or TT) also associated with a modest increased risk for developing breast cancer in the West-Irish cohort (OR = 1.4, 95% CI 1.1-1.8, p = 0.033). More importantly, patients with the BRCA1-3’UTR-variant had a 4-fold increased risk of presenting with Stage IV disease (p = 0.018, OR = 3.37, 95% CI 1.3-11.0). Supporting that this finding is due to tumor biology, and not difficulty screening, obese women with the BRCA1-3’UTR-variant had significantly less dense breasts (p = 0.0398) in the

    The purpose of this study was to evaluate the occurrence of lymphatic drainage to non-axillary sentinel nodes and to determine the implications of this phenomenon. A total of 549 breast cancer patients underwent lymphoscintigraphy after intratumoural injection of 99mTc-nanocolloid. The sentinel node was intraoperatively identified with the aid of intratumoural administered patent blue dye and a gamma-ray detection probe. Histopathological examination of sentinel nodes included step-sectioning at six levels and immunohistochemical staining. A sentinel node outside level I or II of the axilla was found in 149 patients (27%): internal mammary sentinel nodes in 86 patients, other non-axillary sentinel nodes in 44 and both internal mammary and other non-axillary sentinel nodes in nineteen patients. The intra-operative identification rate was 80%. Internal mammary metastases were found in seventeen patients and metastases in other non-axillary sentinel nodes in ten patients. Staging improved in 13% of patients with non-axillary sentinel lymph nodes and their treatment strategy was changed in 17%. A small proportion of clinically node negative breast cancer patients can be staged more precisely by biopsy of sentinel nodes outside level I and II of the axilla, resulting in additional decision criteria for postoperative regional or systemic therapy.

    Surgery is the mainstay of treatment in early- and intermediate-stage non-small cell lung cancer (NSCLC), yet recurrences are frequent. Studies have documented the benefits of chemotherapy administered after resection, but a number of questions remain regarding how overall outcomes can be further improved. To provide the oncology community with direction on these issues, a consensus conference of leading experts in the NSCLC field was held at the Fifth Annual Atlanta Lung Cancer Symposium on October 25-27, 2007. The available scientific literature is presented and when such literature is lacking, clinical experience is provided to support the following conclusions. Preoperative staging should be done in accordance with the National Comprehensive Cancer Network guidelines, but endoscopic fine needle aspiration of enlarged mediastinal nodes can be used, and if histology is positive for malignancy, mediastinoscopy can be avoided. Neoadjuvant systemic therapy is not generally recommended but can be considered to downstage an unresectable patient. There is currently no role for preoperative radiation or chemoradiation. Adjuvant systemic therapy is not recommended for stage IA and IB patients; however, adverse prognostic factors are acceptable reasons to consider adjuvant systemic therapy in the latter. Adjuvant systemic therapy is recommended for stage IIA, IIB, and IIIA patients, consistent with recent American Society of Clinical Oncology guidelines. A cisplatin-based regimen should be started within 60 days after surgery, but if relatively contraindicated, carboplatin is an acceptable alternative. Adjuvant radiation therapy is not recommended for N0 and N1 patients, but is used in N2 patients to decrease local recurrence. PMID:18779538

    Objective: Although Helicobacterpylori (H.pylori) is considered as the main etiological factor for gastric cancer, the strategy of screening and treating the oncogenic bacterium is still controversial.The objective was to evaluate the status and progress of the cognition about the relationship between H.pylori infection and gastric cancer from a clinical aspect.Data Sources: The data used in this review were mainly from the PubMed articles published in English from 1984 to 2015.Study Selection: Clinical research articles were selected mainly according to their level of relevance to this topic.Results: Gastric cancer is the fifth most common malignancy and the third leading cause of cancer deaths worldwide.The main etiological factor for gastric cancer is H.pylori infection.About 74.7-89.0% gastric cancer was related to H.pylori infection.Up to date, some regional gastric cancer prevention programs including the detection and treatment of H.pylori infection are under way.Current data obtained from the randomized controlled trials suggest that population-based H.pylori screening and treatment is feasible and cost-effective in preventing gastric cancer;however, a population-based H.pylori eradication campaign would potentially lead to bacterial resistance to the corresponding antibiotics, as well as a negative impact on the normal flora.Conclusions: The important questions of feasibility, program costs, appropriate target groups for intervention, and the potential harm of mass therapy with antibiotics must first be answered before implementing any large-scale program.

    Full Text Available Background: Free radical Injury is associated with cancer, but how the extent of oxidative stress correlates with the FIGO (International Federation of Gynecology and Obstetrics stage in Carcinoma Cervix (Ca Cx, and its significance as a prognostic marker, is not clear and needs an in-depth study. Aim: To correlate the blood levels of Lipid Peroxidation (LPO, Reduced Glutathione (GSH, Superoxide Dismutase (SOD, and Vitamin A and E levels with the clinical stage in Ca Cx. Settings and Design: This is a Prospective Case Control Study. Materials and Methods: LPO, SOD, reduced GSH were estimated by Bio Chemical Assays and Vitamins by High Performance Liquid Chromatography (HPLC. Statistical Analysis: The cases and controls were compared using One Way ANOVA and different stages over different time periods were individually compared by Repeated Measure Analysis of Variance. Results: The results indicated a statistically significant increase of LPO vis-a-vis the FIGO stage of Ca Cx and control, while the antioxidant status as depicted by GSH and SOD decreased. Vitamin A and E levels were significantly lower in cancer cases as compared to the control. Conclusion: Increased LPO and reduced antioxidant levels may be taken as associated predictive markers, thus suggesting that Ca Cx cases should get nutritive supplements to contain the blood LPO level and maintain a positive balance of antioxidants for a better outcome in terms of delayed recurrence and better Quality of Life (QOL.

  13. Identification of Gene-Expression Signatures and Protein Markers for Breast Cancer Grading and Staging.

    Directory of Open Access Journals (Sweden)

    Full Text Available The grade of a cancer is a measure of the cancer's malignancy level, and the stage of a cancer refers to the size and the extent that the cancer has spread. Here we present a computational method for prediction of gene signatures and blood/urine protein markers for breast cancer grades and stages based on RNA-seq data, which are retrieved from the TCGA breast cancer dataset and cover 111 pairs of disease and matching adjacent noncancerous tissues with pathologists-assigned stages and grades. By applying a differential expression and an SVM-based classification approach, we found that 324 and 227 genes in cancer have their expression levels consistently up-regulated vs. their matching controls in a grade- and stage-dependent manner, respectively. By using these genes, we predicted a 9-gene panel as a gene signature for distinguishing poorly differentiated from moderately and well differentiated breast cancers, and a 19-gene panel as a gene signature for discriminating between the moderately and well differentiated breast cancers. Similarly, a 30-gene panel and a 21-gene panel are predicted as gene signatures for distinguishing advanced stage (stages III-IV from early stage (stages I-II cancer samples and for distinguishing stage II from stage I samples, respectively. We expect these gene panels can be used as gene-expression signatures for cancer grade and stage classification. In addition, of the 324 grade-dependent genes, 188 and 66 encode proteins that are predicted to be blood-secretory and urine-excretory, respectively; and of the 227 stage-dependent genes, 123 and 51 encode proteins predicted to be blood-secretory and urine-excretory, respectively. We anticipate that some combinations of these blood and urine proteins could serve as markers for monitoring breast cancer at specific grades and stages through blood and urine tests.

    Barrett’s esophagus (BE) is the only known precursor to esophageal adenocarcinoma (EAC), whose incidence has increased sharply in the last 4 decades. The annual conversion rate of BE to cancer is significant, but small. The identification of patients at a higher risk of cancer therefore poses a clinical conundrum. Currently, endoscopic surveillance is recommended in BE patients, with the aim of diagnosing either dysplasia or cancer at early stages, both of which are curable with minimally inv...

    Purpose: To evaluate the effect of postmastectomy radiotherapy (PMRT) in Stage II-III breast cancer patients with negative lymph nodes (pN0) after neoadjuvant chemotherapy (NAC). Patients and Materials: Of 1,054 breast cancer patients treated with NAC at our institution between 1990 and 2004, 134 had pN0 status after NAC and mastectomy. The demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The effect of PMRT on locoregional recurrence-free survival and overall survival (OS) was evaluated by multivariate analysis, including known prognostic factors. Results: Of the 134 eligible patients, 78 (58.2%) received PMRT and 56 (41.8%) did not. At a median follow-up time of 91.4 months, the 5-year locoregional recurrence-free survival and OS rate was 96.2% and 88.3% with PMRT and 92.5% and 94.3% without PMRT, respectively (p = NS). The corresponding values at 10 years were 96.2% and 77.2% with PMRT and 86.8% and 87.7% without PMRT (p = NS). On multivariate analysis, PMRT had no effect on either locoregional recurrence-free survival (hazard ratio, 0.37; 95% confidence interval, 0.09-1.61; p = .18) or OS (hazard ratio, 2.06; 95% confidence interval, 0.71-6; p = .18). This remained true in the subgroups of patients with clinical Stage II or Stage III disease at diagnosis. A trend was seen toward poorer OS among patients who had not had a pathologic complete in-breast tumor response after NAC (hazard ratio, 6.65; 95% confidence interval, 0.82-54.12; p = .076). Conclusions: The results from the present retrospective study showed no increase in the risk of distant metastasis, locoregional recurrence, or death when PMRT was omitted in breast cancer patients with pN0 status after NAC and mastectomy. Whether the omission of PMRT is acceptable for these patients should be addressed prospectively.

    Approximately 60 percent of patients diagnosed with cancer present as early stage disease (Stage I and II). Despite the favorable prognosis associated with treatment intervention of such early stage disease (typically surgical excision), there are a small, but significant, fraction of these cancers that appear to be hardwired for aggressive metastatic behavior and ultimately lethal outcome.

  18. Stage-to-Stage Comparison of Preoperative and Postoperative Chemoradiotherapy for T3 Mid or Distal Rectal Cancer

    International Nuclear Information System (INIS)

    Purpose: To investigate, in a comparative analysis, the prognostic implications of postchemoradiotherapy (post-CRT) pathologic stage (ypStage) vs. postoperative pathologic stage (pStage) in rectal cancer. Methods and Materials: Between May 2001 and December 2006, 487 patients with T3 mid or distal rectal cancer were analyzed retrospectively. Concurrent CRT was administered preoperatively (n = 364, 74.7%) or postoperatively (n = 123, 25.3%). The radiation dose was 50.4 Gy in 28 fractions. All patients underwent a total mesorectal excision and received adjuvant chemotherapy. Disease-free survival (DFS) was estimated using the Kaplan-Meier method. Differences in DFS, stratified by ypStage and pStage, were compared using the log–rank test. Results: For surviving patients, the median follow-up period was 68 months (range, 12–105 months). The 5-year local recurrence-free survival rate was not different, at 95.3% and 92.1% in preoperative and postoperative CRT groups, respectively (p = 0.402), but the 5-year distant metastasis-free survival rate was significantly different, at 81.6% (preoperative CRT) vs. 65.4% (postoperative CRT; p = 0.001). The 5-year DFS rate of 78.8% in the preoperative CRT group was significantly better than the 63.0% rate in the postoperative CRT group (p = 0.002). Post-CRT pathologic Stage 0–I occurred in 42.6% (155 of 364) of the patients with preoperative CRT. The 5–year DFS rates were 90.2% (ypStage 0–I), 83.5% (ypStage II), 77.3% (pStage II), 58.6% (ypStage III), and 54.7% (pStage III). The DFS rate of ypStage 0–I was significantly better than that of ypStage II or pStage II. Post-CRT pathologic Stage II and III had similar DFS, compared with pStage II and III, respectively. Conclusions: Disease-free survival predicted by each ypStage was similar to that predicted by the respective pStage. Improved DFS with preoperative vs. postoperative CRT was associated with the ypStage 0–I group that showed a similarly favorable outcome to pStage

    Full Text Available Background: Skin cancer is the most frequent neoplasia in the world. Even though ultraviolet radiation is the main cause, established prevention campaigns have not proved to be effective for controlling the incidence of this disease. Objective: To develop clinical prediction rules based on medical consultation and a questionnaire to estimate the risk of developing nonmelanoma skin cancer. Methods: This study was developed in several steps. They were: Identifying risk factors that could be possible predictors of nonmelanoma skin cancer; their clinical validation; developing a prediction rule using logistic regression; and collecting information from 962 patients in a case and control design (481 cases and 481 controls. We developed independent prediction rules for basal cell and squamous cell carcinomas. Finally, we evaluated reliability for each of the variables. Results: The variables that made up the final prediction rule were: Family history of skin cancer, history of outdoor work, age, phototypes 1-3 and the presence of poikiloderma of civatte, actinic keratosis and conjunctivitis in band. Prediction rules specificity was 87% for basal cell carcinomas and 92% for squamous cell carcinomas. Inter- and intra-observer reliability was good except for the conjunctivitis in band variable. Conclusions: The prediction rules let us calculate the individual risk of developing basal cell carcinoma and squamous cell carcinoma. This is an economic easy-to-apply tool that could be useful in primary and secondary prevention of skin cancer.

    Full Text Available Abstract Background Alterations of mitochondrial DNA (mtDNA have been implicated in carcinogenesis. We developed an accurate multiplex quantitative real-time PCR for synchronized determination of mtDNA and nuclear DNA (nDNA. We sought to investigate whether mtDNA content in the peripheral blood of breast cancer patients is associated with clinical and pathological parameters. Methods Peripheral blood samples were collected from 60 patients with breast cancer and 51 age-matched healthy individuals as control. DNA was extracted from peripheral blood for the quantification of mtDNA and nDNA, using a one-step multiplex real-time PCR. A FAM labeled MGB probe and primers were used to amplify the mtDNA sequence of the ATP 8 gene, and a VIC labeled MGB probe and primers were employed to amplify the glyceraldehyde-3-phosphate-dehydrogenase gene. mtDNA content was correlated with tumor stage, menstruation status, and age of patients as well as lymph node status and the expression of estrogen receptor (ER, progesterone receptor (PR and Her-2/neu protein. Results The content of mtDNA in stage I breast cancer patients was significantly lower than in other stages (overall P = 0.023. Reduced mtDNA was found often in post menopausal cancer group (P = 0.024. No difference in mtDNA content, in regards to age (p = 0.564, lymph node involvement (p = 0.673, ER (p = 0.877, PR (p = 0.763, and Her-2/neu expression (p = 0.335, was observed. Conclusion Early detection of breast cancer has proved difficult and current detection methods are inadequate. In the present study, decreased mtDNA content in the peripheral blood of patients with breast cancer was strongly associated with stage I. The use of mtDNA may have diagnostic value and further studies are required to validate it as a potential biomarker for early detection of breast cancer.

    Clinical studies have shown compelling data of elevated biopotential signals recorded noninvasively from the breasts of women with breast cancer. While these data are compelling and show a strong potential for use in the noninvasive early detection of breast cancer, there remains significant knowledge gaps which must be addressed before this technology can be routinely used for breast cancer detection. A diffusion-drift model is developed to study the spatial and temporal characteristics of the biopotential signals of breast tumors taking into account the morphology and cell division stages. The electric signals of the most common tumor types—papillary, compact, and comedo—are also considered. The largest biopotential signal is observed from the compact tumor, while the smallest signal is observed from the papillary type. The results also show an increase in the time duration of the generated biopotential signals when cancer cells start their transitions at different time instants. The spatial and temporal variations of the biopotential signals are correlated with the tumor pattern which can have important implications for breast cancer detection.

    As anticancer therapies designed to target specific molecular pathways have been developed, it has become critical to develop methods to assess the response induced by such agents. Although traditional, anatomic CT, and MRI examinations are useful in many settings, increasing evidence suggests that these methods cannot answer the fundamental biologic and physiologic questions essential for assessment and, eventually, prediction of treatment response in the clinical trial setting, especially in the critical period soon after treatment is initiated. To optimally apply advances in quantitative imaging methods to trials of targeted cancer therapy, new infrastructure improvements are needed that incorporate these emerging techniques into the settings where they are most likely to have impact. In this review, we first elucidate the needs for therapeutic response assessment in the era of molecularly targeted therapy and describe how quantitative imaging can most effectively provide scientifically and clinically relevant data. We then describe the tools and methods required to apply quantitative imaging and provide concrete examples of work making these advances practically available for routine application in clinical trials. We conclude by proposing strategies to surmount barriers to wider incorporation of these quantitative imaging methods into clinical trials and, eventually, clinical practice. Our goal is to encourage and guide the oncology community to deploy standardized quantitative imaging techniques in clinical trials to further personalize care for cancer patients and to provide a more efficient path for the development of improved targeted therapies.

    Full Text Available Background and objective It is common recognized that young patients of lung cancer have poor prognosis due to relatively higher malignancy and more invasive growth. In the past most studies on young patients of lung cancer selected patients younger than 40 or 45 years old, and there were few clinical materials for younger patients under 30 years. This study retrospectively described the the disease history, stage, treatment and pathology features of lung cancer patients younger than 30 years and aimed to provide references for these patients. Methods Those patients younger than 30 years, once admitted in the General Hospital of the People's Liberation Army for lung cancer from 1993 to date, were sought in medical record system, and 53 patients were found in total. In this group, there were 34 non-small cell lung cancer (NSCLC patients and 19 small cell lung cacer (SCLC patients. The male/female ratio was 1.5:1. In the NSCLC patients, there were 27 adenocarcinomas, 6 squamous carcinomas and 1 adenosquamous carcinoma, with no large cell carcinoma involved. In these patients, 12 patients received operations while 38 patients got chemo- and/or radiotherapy and 3 quited any treatment. Results There was no death in hospital, however, in the 12 patients who got operation, only 8 patients got complete resection while 4 patients got palliative resection. Conclusion Lung cancer patients younger than 30 years had a high fraction of adenocarcinoma and small cell type pathologically and most of them were in late stage when presenting with symptoms in hospital and would have a dismal prognosis. The routine health examination and early diagnosis should be emphasized to improve the prognosis of these patients.

  8. Preoperative chemoradiotherapy using superselective intraarterial infusion via superficial temporal artery for stage III, IV oral cancer

    International Nuclear Information System (INIS)

    Thirty-eight patients with stage III, IV oral cancer were treated by preoperative chemoradiotherapy using superselective intraarterial infusion via the superficial temporal artery. Radiotherapy (total dose: 40 Gy) and chemotherapy using CBDCA (total dose: 460 mg/m2) were performed daily, followed by surgery. Catheter-insertion of 34 patients was done successfully. Four catheter insertions were not done successfully because of the anomaly of the artery such as common trunk of the lingual artery and the facial artery. The clinical effects were CR in 9 patients (26.5%) and PR in 25 (73.5%), and histopathological effects after surgery were grade III, IV in 10 (29.4%), grade IIb in 23 (67.6%), and grade IIa in 2 (5.8%). The 5-year cumulative survival rate was 67.8%. This superselective intra arterial infusion method could be the technique of choice for the treatment of oral cancer. (author)

    In advanced cancer patients, the oxidative stress could take place either at the onset of disease or as a function of disease progression. To test this hypothesis, the following parameters were investigated: the erythrocyte activity of the enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx), the serum activity of glutathione reductase (GR) and the serum total antioxidant status (TAS). The total antioxidant capacity of plasma LMWA was evaluated by the cyclic voltammetry methodology. We further determined the serum levels of proinflammatory cytokines (IL-6 and TNFalpha), IL-2, leptin and C-reactive protein (CRP). All of these parameters have been correlated with the most important clinical indices of patients such as Stage of disease, ECOG PS and clinical response. Eighty-two advanced stage cancer patients and 36 healthy individuals used as controls were included in the study. Our findings show that SOD activity was significantly higher in cancer patients than in controls and GPx activity was significantly lower in cancer patients than in controls. Serum values of IL-6, TNFalpha and CRP were significantly higher in patients than in controls. Serum leptin values of cancer patients were significantly lower than controls. SOD activity increased significantly from Stage II/ECOG 0-1 to Stage IV/ECOG 0-1, whereas it decreased significantly in Stage IV/ECOG 3. GPx activity decreased significantly in Stage IV/ECOG 2-3. An inverse correlation between ECOG PS and serum leptin levels was found. Serum levels of IL-2 decreased from Stage II/ECOG 0-1 to Stage IV/ECOG 2-3. A direct correlation between Stage/ECOG PS and serum levels of both IL-6 and CRP was observed. Cisplatin administration induced a significant increase of GPx after 24 hr. In conclusion, this is the first study that shows that several "biological" parameters of cancer patients such as antioxidant enzyme activity, cytokines, leptin and CRP strictly correlate with the most important clinical

    We retrospectively studied the staging accuracy of endorectal magnetic resonance imaging (MRI) in comparison with transrectal ultrasound examination (TRUS) for 71 localized bladder cancers and 19 localized prostate cancers (PC) radically resected. The accuracy of clinical staging for bladder cancer in endorectal MRI and TRUS was 85.9% and 69.2%, respectively. The presence or absence of the continuity of submucosal enhancement on T2-weighted MRI images could be useful for the staging of bladder cancer. The accuracy of the seminal vesicular invasion for prostate cancer in endorectal MRI and TRUS was 95% and 63%, respectively. To determine whether magnetization transfer contrast (MTC) provides additional information in the diagnosis of prostate cancer, the magnetization transfer ratios (MTRs) were calculated in 22 patients with PC, 5 with benign prostatic hyperplasia (BPH) and 4 controls. The mean MTR in the peripheral zone of the normal prostate (8.0%{+-}3.4 [standard deviation]) showed a statistically significant decrease relative to that in the inner zone of the normal prostate (27.4%{+-}3.4, p<0.01), BPH (25.5%{+-}3.7, p<0.01), pre-treatment PC (30.6%{+-}5.9, p<0.01), and PC after hormonal therapy (20.3%{+-}6.3, p<0.01). The mean MTR in pre-treatment PC was significantly higher than that in BPH, or in PC after hormonal therapy (p<0.01). MTC was considered to be useful for conspicuity of prostate cancer lesion.

  12. Expression of Eph receptor A10 is correlated with lymph node metastasis and stage progression in breast cancer patients

    International Nuclear Information System (INIS)

    Eph receptor A10 (EphA10) is a valuable breast cancer marker that is highly expressed in breast cancer tissues by comparison with normal breast tissues, as we previously reported. However, the role of EphA10 expression in breast cancer is not well understood. Here, we have analyzed the expression of EphA10 at the mRNA- and protein-level in clinical breast cancer tissues and then evaluated the relationship with clinicopathological parameters for each sample. EphA10 mRNA expression was quantified by real-time polymerase chain reaction using complimentary DNA (cDNA) samples derived from breast cancer patients. Lymph node (LN) metastasis and stage progression were significantly correlated with EphA10 expression at the mRNA level (P = 0.0091 and P = 0.034, respectively). Furthermore, immunohistochemistry (IHC) staining of breast cancer tissue microarrays (TMAs) revealed that EphA10 expression at the protein level was also associated with LN metastasis and stage progression (P = 0.016 and P = 0.011, respectively). These results indicate that EphA10 expression might play a role in tumor progression and metastasis. Our findings will help elucidate the role of EphA10 in clinical breast cancer progression

    1990-01-01

    A controlled randomized clinical trial was conducted to examine the efficacy of topical low dose heparin (0.125 gm./l., 25,000 units per l.) as prophylaxis against recurrent noninvasive (stage Ta) transitional cell bladder cancer. Transurethral tumor resection was done with irrigation fluid...... containing either 1.5% glycine with heparin or glycine solution alone. Tumor recurrence was determined by cystoscopy 4 to 6 months later. There were 70 patients evaluated: 38 in the heparin and 32 in the control group, respectively. The recurrence rate (heparin 74%, control 66%) and the median number...... of recurrences (heparin 3, range 1 to 15 and control 3, range 1 to 30) were similar (p greater than 0.05) in the 2 groups of patients. These observations show that low dose heparin administered in the irrigation fluid during transurethral resection does not decrease the recurrence rate of noninvasive (stage Ta...

    Purpose/Objectives(s): Early-stage endometrial cancer patients are at higher risk of noncancer mortality than of cancer mortality. Competing event models incorporating comorbidity could help identify women most likely to benefit from treatment intensification. Methods and Materials: 67,397 women with stage I-II endometrioid adenocarcinoma after total hysterectomy diagnosed from 1988 to 2009 were identified in Surveillance, Epidemiology, and End Results (SEER) and linked SEER-Medicare databases. Using demographic and clinical information, including comorbidity, we sought to develop and validate a risk score to predict the incidence of competing mortality. Results: In the validation cohort, increasing competing mortality risk score was associated with increased risk of noncancer mortality (subdistribution hazard ratio [SDHR], 1.92; 95% confidence interval [CI], 1.60-2.30) and decreased risk of endometrial cancer mortality (SDHR, 0.61; 95% CI, 0.55-0.78). Controlling for other variables, Charlson Comorbidity Index (CCI) = 1 (SDHR, 1.62; 95% CI, 1.45-1.82) and CCI >1 (SDHR, 3.31; 95% CI, 2.74-4.01) were associated with increased risk of noncancer mortality. The 10-year cumulative incidences of competing mortality within low-, medium-, and high-risk strata were 27.3% (95% CI, 25.2%-29.4%), 34.6% (95% CI, 32.5%-36.7%), and 50.3% (95% CI, 48.2%-52.6%), respectively. With increasing competing mortality risk score, we observed a significant decline in omega (ω), indicating a diminishing likelihood of benefit from treatment intensification. Conclusion: Comorbidity and other factors influence the risk of competing mortality among patients with early-stage endometrial cancer. Competing event models could improve our ability to identify patients likely to benefit from treatment intensification.

    Woloszynska-Read, Anna; Johnson, Candace S.; Trump, Donald L.

    2015-01-01

    There are substantial preclinical and epidemiologic data that suggest that vitamin D plays a role in the prevention and treatment of cancer. Numerous observational studies have shown that low blood levels of 25(OH) vitamin D (cholecalciferol), estimated by geographical location, diet and activity assessment or measured serum levels are associated with a higher risk of cancer and worse cancer-specific survival as well as numerous morbidities to e.g. cardiovascular disease, stroke, infection, autoimmune disease, and neuromuscular dysfunction among large populations. A considerable number of in vitro and in vivo studies indicate that the most active metabolite of vitamin D – 1,25-dihydroxycholecalciferol or calcitriol – has anti-proliferative, pro-apoptotic, pro-differentiating, and anti-angiogenic properties. Combined treatment of calcitriol and many types of cytotoxic agents has synergistic or at least additive effects. However, clinical trials testing these hypotheses have been less encouraging, though a number of methodological, pharmacological, and pharmaceutical issues confound all trials ever conducted. In order to properly assess the clinical value of vitamin D, its metabolites and analogs in cancer prevention and treatment, more studies are needed. PMID:21872802

    Full Text Available Objectives: Hyperfibrinogenemia is a common problem associated with various carcinomas. The recent studies have shown that high plasma fibrinogen concentration is associated with invasion, growth and metastases of cancer. Furthermore, the recent studies focus on the prognostic significance of fibrinogen in the patients with advanced NSCLC (stage IIIB -IV. However, the prognostic significance of the plasma fibrinogen levels in early stage NSCLC patients (stage I -IIIA still remains unclear. In addition, it remains unclear whether or not chemotherapy-induced changes in fibrinogen level relate to the prognosis. The aims of this study were to 1 further explore the relationship between the plasma fibrinogen concentration and the stage and metastases of lung cancer 2 evaluate the prognostic significance of the basal plasma fibrinogen level in patients with lung cancer 3 explore the prognostic value of the change in fibrinogen levels between pre and post-chemotherapy. Methods: In this retrospective study, the data from 370 patients with lung cancer were enrolled into this study. The plasma fibrinogen levels were compared with the clinical and prognostic significance of lung cancer. The association between the plasma fibrinogen level and clinical-prognostic characteristics were analyzed using SPSS 17.0 software. Results: 1 The median pre-treatment plasma fibrinogen levels were 4.20g/L. Pre-treatment plasma fibrinogen levels correlated significantly with gender (p = 0.013. A higher plasma fibrinogen concentration was associated with squamous cell carcinoma versus adenocarcinoma (4.83±1.50 g/L versus 4.15±1.30 g/L; P<0.001, there was a significant association between plasma fibrinogen level and metastases of lung cancer, pointing a higher plasma fibrinogen level in lymph nodes or distant organ metastases (p < 0.001. 2 Patients with low plasma fibrinogen concentration demonstrates higher overall survival compared with those with high plasma fibrinogen

    Immunology-based therapy is rapidly developing into an effective treatment option for a surprising range of cancers. We have learned over the last decade that powerful immunologic effector cells may be blocked by inhibitory regulatory pathways controlled by specific molecules often called“immune checkpoints.” These checkpoints serve to control or turn off the immune response when it is no longer needed to prevent tissue injury and autoimmunity. Cancer cells have learned or evolved to use these mechanisms to evade immune control and elimination. The development of a new therapeutic class of drugs that inhibit these inhibitory pathways has recently emerged as a potent strategy in oncology. Three sets of agents have emerged in clinical trials exploiting this strategy. These agents are antibody-based therapies targeting cytotoxic T-lymphocyte antigen4 (CTLA4), programmed cell death1 (PD-1), and programmed cell death ligand 1 (PD-L1). These inhibitors of immune inhibition have demonstrated extensive activity as single agents and in combinations. Clinical responses have been seen in melanoma, renal cellcarcinoma, non-smal celllung cancer, and several other tumor types. Despite the autoimmune or inflammatory immune-mediated adverse effects which have been seen, the responses and overall survival benefits exhibited thus far warrant further clinical development.

  10. Radiation Therapy, Cardiac Risk Factors, and Cardiac Toxicity in Early-Stage Breast Cancer Patients

    International Nuclear Information System (INIS)

    Purpose: The benefits of adjuvant radiation therapy (RT) for breast cancer may be counterbalanced by the risk of cardiac toxicity. We studied the cardiac effects of RT and the impact of pre-existing cardiac risk factors (CRFs) in a population-based sample of older patients with breast cancer. Methods and Materials: In the Surveillance, Epidemiology and End-Results (SEER)-Medicare database of women ≥65 years diagnosed with Stages I to III breast cancer from January 1, 1992 to December 31, 2000, we used multivariable logistic regression to model the associations of demographic and clinical variables with postmastectomy and postlumpectomy RT. Using Cox proportional hazards regression, we then modeled the association between treatment and myocardial infarction (MI) and ischemia in the 10 or more years after diagnosis, taking the predictors of treatment into account. Results: Among 48,353 women with breast cancer; 19,897 (42%) were treated with lumpectomy and 26,534 (55%) with mastectomy; the remainder had unknown surgery type (3%). Receipt of RT was associated with later year of diagnosis, younger age, fewer comorbidities, nonrural residence, and chemotherapy. Postlumpectomy RT was also associated with white ethnicity and no prior history of heart disease (HD). The RT did not increase the risk of MI. Presence of MI was associated with age, African American ethnicity, advanced stage, nonrural residence, more than one comorbid condition, a hormone receptor-negative tumor, CRFs and HD. Among patients who received RT, tumor laterality was not associated with MI outcome. The effect of RT on the heart was not influenced by HD or CRFs. Conclusion: It appears unlikely that RT would increase the risk of MI in elderly women with breast cancer, regardless of type of surgery, tumor laterality, or history of CRFs or HD, for at least 10 years

    Full Text Available Abstract Background Mass spectrometric analysis of the blood proteome is an emerging method of clinical proteomics. The approach exploiting multi-protein/peptide sets (fingerprints detected by mass spectrometry that reflect overall features of a specimen's proteome, termed proteome pattern analysis, have been already shown in several studies to have applicability in cancer diagnostics. We aimed to identify serum proteome patterns specific for early stage breast cancer patients using MALDI-ToF mass spectrometry. Methods Blood samples were collected before the start of therapy in a group of 92 patients diagnosed at stages I and II of the disease, and in a group of age-matched healthy controls (104 women. Serum specimens were purified and the low-molecular-weight proteome fraction was examined using MALDI-ToF mass spectrometry after removal of albumin and other high-molecular-weight serum proteins. Protein ions registered in a mass range between 2,000 and 10,000 Da were analyzed using a new bioinformatic tool created in our group, which included modeling spectra as a sum of Gaussian bell-shaped curves. Results We have identified features of serum proteome patterns that were significantly different between blood samples of healthy individuals and early stage breast cancer patients. The classifier built of three spectral components that differentiated controls and cancer patients had 83% sensitivity and 85% specificity. Spectral components (i.e., protein ions that were the most frequent in such classifiers had approximate m/z values of 2303, 2866 and 3579 Da (a biomarker built from these three components showed 88% sensitivity and 78% specificity. Of note, we did not find a significant correlation between features of serum proteome patterns and established prognostic or predictive factors like tumor size, nodal involvement, histopathological grade, estrogen and progesterone receptor expression. In addition, we observed a significantly (p = 0

    Highlights: •Models mimicking ECM in tumor with different malignancy were prepared. •Cancer cell proliferation was suppressed on benign tumor ECM. •Benign tumor cell proliferation was suppressed on cancerous ECM. •Chemoresistance of cancer cell was enhanced on cancerous ECM. -- Abstract: Extracellular matrix (ECM) has been focused to understand tumor progression in addition to the genetic mutation of cancer cells. Here, we prepared “staged tumorigenesis-mimicking matrices” which mimic in vivo ECM in tumor tissue at each malignant stage to understand the roles of ECM in tumor progression. Breast tumor cells, MDA-MB-231 (invasive), MCF-7 (non-invasive), and MCF-10A (benign) cells, were cultured to form their own ECM beneath the cells and formed ECM was prepared as staged tumorigenesis-mimicking matrices by decellularization treatment. Cells showed weak attachment on the matrices derived from MDA-MB-231 cancer cells. The proliferations of MDA-MB-231 and MCF-7 was promoted on the matrices derived from MDA-MB-231 cancer cells whereas MCF-10A cell proliferation was not promoted. MCF-10A cell proliferation was promoted on the matrices derived from MCF-10A cells. Chemoresistance of MDA-MB-231 cells against 5-fluorouracil increased on only matrices derived from MDA-MB-231 cells. Our results showed that the cells showed different behaviors on staged tumorigenesis-mimicking matrices according to the malignancy of cell sources for ECM preparation. Therefore, staged tumorigenesis-mimicking matrices might be a useful in vitro ECM models to investigate the roles of ECM in tumor progression.

    Over 15 years ago, low-dose metronomic chemotherapy was shown to induce disease control in patients with advanced-stage breast cancer with a lower incidence of adverse events compared with conventional maximum tolerated dose chemotherapy. Good response rates have been seen in heavily pre-treated patients for whom limited treatment options are available. Most patients prefer oral therapy and metronomic chemotherapy is a convenient alternative in patients with advanced-stage disease in which minimal toxicity and good tumour control are the overall aims of treatment. The addition of metronomic protocols to standard neoadjuvant chemotherapy regimens has produced promising pathological complete response rates. Ongoing trials including the SYSUCC-001 trial in patients with triple-negative breast cancer and the IBCSG 22-00 trial that is assessing a cyclophosphamide-methotrexate maintenance regimen after standard adjuvant therapy in hormone receptor-negative disease, will clarify the value of adding this approach to conventional therapies. The low cost associated with metronomic chemotherapy represents an opportunity for the utilization of this treatment option, especially in developing countries, and poses a challenge for the launch of large trials sponsored by industry. Using breast cancer as the principal example, we discuss the key clinical advances in this area, including new trial design, appropriate patient and end point selection, as well as the evolving rationale for metronomic chemotherapy combinations.

    2015-01-01

    Transforming growth factor-β(TGF-β) is a key factor in cancer development and progression. TGF-βcan suppress tumorigenesis by inhibiting cell cycle progression and stimulating apoptosis in early stages of cancer progression. However, TGF-βcan modulate cancer-related processes, such as cell invasion, distant metastasis, and microenvironment modiifcation that may be used by cancer cells to their advantage in late stages. Corresponding mechanisms include angiogenesis promotion, anti-tumor immunity suppression, and epithelial-to-mesenchymal transition (EMT) induction. hTe correlation between TGF-βexpression and cancer prognosis has also been extensively investigated. Results suggest that TGF-βpathway can be targeted to treat cancer;as such, the feasibility of this treatment is investigated in clinical trials.

    Full Text Available Early detection of cancer is an effective and efficient cancer management strategy. In South Korea, the National Health Insurance administers the National Cancer Screening Program to its beneficiaries. We examined the impact of the National Cancer Screening Program on socioeconomic disparities in cancer stage at diagnosis.Cancer patients registered in the Korean Central Cancer Registry from January 1, 2010 to December 31, 2010 with a diagnosis of gastric cancer (n = 22,470, colon cancer (n = 16,323, breast cancer (n = 10,076, or uterine cervical cancer (n = 2,447 were included. Income level was divided into three groups according to their monthly contribution of National Health Insurance. We employed absolute (age-standardized prevalence rate, slope index of inequality and relative (relative index of inequality measures to separately examine social disparities among participants and non-participants of the National Cancer Screening Program in terms of the early-stage rate.Age-standardized prevalence rates of early-stage by income group were always higher in participants than in non-participants. Furthermore, the age-standardized prevalence rate of early-stage in the low income group of the participants was also higher than that of the high income group of the non-participants. The sizes of disparities (both slope index of inequality and relative index of inequality are smaller in participants compared to non-participants.National Cancer Screening Program participation reduced income disparity in cancer stage at diagnosis. Population-based cancer screening programs can be used as an effective measure to reduce income disparity in cancer care.

    2016-01-01

    Proton-beam therapy (PBT) for prostate cancer has been in used for several decades, with its technique evolving significantly over this period. A growing number of centers now routinely utilize pencil-beam scanning as an advanced technique of PBT. Interest and controversy concerning its use have recently come under scrutiny. While the past decade has produced an assemblage of evidence suggesting that PBT is safe and effective for early stage prostate cancer, it is still unknown whether the theoretical dosimetric advantages of PBT translate into meaningful clinical improvements over routine intensity-modulated radiation therapy, which is commonly used for these patients. Outcomes from early trials using whole courses of PBT have shown mixed results when compared with routine intensity-modulated radiation therapy. Therefore, randomized trials comparing these two techniques should be undertaken, as this would help in defining the role of PBT for this patient group. This article aims to describe the basics of PBT, review the reasons for the growing interest in PBT, review the evidence for PBT, review the controversy surrounding PBT, and inquire about PBT's future in the treatment of prostate cancer, with attention to its physical properties, comparative clinical and cost-effectiveness, and advances in its delivery.

    Full Text Available Background: National Cancer Institute phase I #7336 and phase II #8327 clinical trials explored the safety and efficacy of triapine (NSC #663249 added to cisplatin radiochemotherapy in untreated patients with advanced-stage cervical cancer. Triapine inhibits ribonucleotide reductase, the rate-limiting enzyme responsible for DNA-building deoxyribonucleotides, and thereby, enhances radiochemosensitivity by prolonging DNA repair time. Here we report 3-year efficacy endpoints of pelvic locoregional relapse rate, disease-free and overall survivals. Methods: Eligible patients with bulky IB-IIIB cervical cancer underwent three-times weekly triapine (25 or 50 mg/m2, once-weekly cisplatin (40mg/m2, and conventional daily pelvic radiation followed by brachytherapy. A cumulative incidence method estimated pelvic locoregional relapse rates. Disease-free survival was measured from radiochemotherapy start date to the date of first relapse or cancer-related death. Overall survival was measured from radiochemotherapy start date to the date of any-cause death. The Kaplan-Meier method estimated survivals. Findings: Between 2006 and 2011, 24 untreated patients with cervical cancer met criteria for reporting in this study. A median 3.4 years of follow-up time (range, 0.3-7.6 years has been observed. All had squamous cancers and the majority had either node-positive stage IB-IIA (33% or stage IIIB (42% disease. The 3-year pelvic locoregional relapse rate, disease-free survival, and overall survival were 4% (95% confidence interval [CI], 0-20%, 80% (95% CI: 71-89%, and 82% (95% CI: 74%-90%, respectively. Interpretation: Triapine radiochemotherapy was safe, active, and effective in patients with untreated advanced-stage cervical cancer, worthy of randomized clinical trial study.Funding: National Institutes of Health grants U01 CA62502 and P30 CA43703-17

    Full Text Available Breast cancer is the most common cancer among women worldwide. Breast cancer metastasis primarily happens through lymphatic system, where the extent of lymph node metastasis is the major factor influencing staging, prognosis and therapeutic decision of the disease. We aimed to study the protein expression changes in different N (regional lymph nodes stages of breast cancer. Protein expression profiles of breast cancerous and adjacent normal tissues were mapped by proteomics approach that comprises of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE and tandem mass spectrometry (LC-MS/MS analysis. Calreticulin and tropomyosin alpha 3 chains were the common up-regulated proteins in N0, N1 and N2 stages of breast cancer. Potential biomarker for each N stage was HSP 70 for N0, 80 k protein H precursor and PDI for N1 stage while 78 kDa glucose-regulated protein was found useful for N2 stage. In addition, significant up-regulation of PDI A3 was detected only in the metastasized breast cancer. The up-regulation expression of these proteins in cancerous tissues can potentially use as indicators for diagnosis, treatment and prognosis of different N stages of breast cancer.

    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.

    OBJECTIVE To evaluate the efficiency of surgery plus radiotherapy and chemotherapy versus radiotherapy plus chemotherapy in the treatment of older patients with stage I or II cervical carcinoma and to seek suitable treatment for such patients. METHODS The clinical data of 179 elderly women with stage la or lib cervical cancer were analyzed retrospectively. One hundred and thirty-four cases underwent radical hysterectomy followed by adjuvant radiotherapy and/or chemotherapy (Group 1). Forty-five cases underwent radiation therapy plus adjuvant chemotherapy (Group 2). RESULTS The 5-year survival rates in group 1 and group 2 were 78.3% and 49.1%(P=0.04), respectively. The incidence of complications in group1 was 47.0%. Three patients died of complications after radical hysterectomy. The incidence of complications in group 2 was 75.6%. CONCLUSION Elderly patients with stage I or II cervical carcinoma should receive an operation if possible. In addition they should receive adjuvant treatments according to their personal conditions, and be treated with appropriate adjuvant chemo-and/or radiotherapy.

  13. Concomitant postoperative radio-chemotherapy in high risk patients with cervical cancer stage IB and HA

    International Nuclear Information System (INIS)

    The aim of the study was to compare the treatment results, prognostic factors and toxicity of radiotherapy when used alone or in combination with Cisplatin in patients with early stage cervical cancer - clinical stage I and MA by RGO, who are in high risk group due to: positive (metastatic) lymph nodes (N+), positive resection line (R+) and have hydronephrosis. For a 5-year period (2007-2012) there were 252 patients with cervical cancer stage IB and MA, who were operated by Wertheim - Meigs, 165 of them received postoperative chemotherapy (Cisplatin) and external beam radiotherapy, while the remaining 87 external beam radiotherapy only. In pelvic region the total dose was 50Gy in daily dose 2Gy in 5 fractions/ week simultaneously with Cisplatin 40 mg/m2 once/ week to total dose 200 - 250 mg.There is an improvement with 8% of 5-years overall survival in the radio-chemotherapy group. Study results signify statistically significant advantage in total survival rate when using combined radio-chemotherapy in patients without accompanying hydronephrosis (p=0.00001), who had negative resection line R0 (p=0,003) and were in 11 clinical stage (p=0.012). There is also a statistically significant correlation between patients with T2 tumors with positive (metastatic) lymph nodes (N+) - 63.2% (p=0.01) and those with T2 tumors with positive resection line (R+) - 56.6% (p=0.01). There was local recurrence in 50% of patients with R+, and in patients with hydronephrosis when N+. Patients in the group on simultaneous radio- and chemotherapy experienced an acceptable early hematological (grade 1) and intestinal toxicity. Use of Cisplatin improves the treatment results. Local recurrence in 50% of R+ patient, as well as in those with accompanying hydronephrosis due to parailliac lymph nodes metastases raise the question for precise p re-treatment staging and the need of dose increase above 50 Gy, regardless the use of Cisplatin.

    Full Text Available Background/Aim. Cancer, one of the leading causes of mortality in the world, imposes a substantial economic burden on each society, including Serbia. The aim of this study was to evaluate the major cancer cost drivers in Serbia. Methods. A retrospective, indepth, bottom-up analysis of two combined databases was performed in order to quantify relevant costs. End-of-life data were obtained from patients with cancer, who deceased within the first year of the established diagnose, including basic demographics, diagnosis, tumour histology, medical resource use and related costs, time and cause of death. All costs were allocated to one of the three categories of cancer health care services: primary care (included home care, hospital outpatient and hospital inpatient care. Results. Exactly 114 patients were analyzed, out of whom a high percent (48.25% had distant metastases at the moment of establishing the diagnosis. Malignant neoplasms of respiratory and intrathoracic organs were leading causes of morbidity. The average costs per patient were significantly different according to the diagnosis, with the highest (13,114.10 EUR and the lowest (4.00 EUR ones observed in the breast cancer and melanoma, respectively. The greatest impact on total costs was observed concerning pharmaceuticals, with 42% of share (monoclonal antibodies amounted to 34% of all medicines and 14% of total costs, followed by oncology medical care (21%, radiation therapy and interventional radiology (11%, surgery (9%, imaging diagnostics (9% and laboratory costs (8%. Conclusion. Cancer treatment incurs high costs, especially for end-of-life pharmaceutical expenses, ensued from medical personnel tendency to improve such patients’ quality of life in spite of nearing the end of life. Reimbursement policy on monoclonal antibodies, in particular at end-stage disease, should rely on cost-effectiveness evidence as well as documented clinical efficiency. [Projekat Ministarstva nauke

    The aim of this study is to report survival and results of therapy and possible prognostic factors in women with pathologic stage II endometrial carcinoma. Forty-two patients with pathologic stage II endometrial carcinoma were treated at the department of Radiation Oncology of the Medisch Spectrum Twente between 1987 and 1998. All patients received external radiotherapy following standard surgical procedures and no adjuvant systemic therapy was given. From the 42 patients 21 had a pathologic stage IIA and 21 stage IIB. The median follow-up was 62 months. The overall recurrence rate was 21.5% (9/42). Seven patients had distant metastasis, of which three also had locoregional recurrence, vaginal vault and/or pelvic. The presence of myometrial invasion (> (1/2)) and/or lymph-angioinvasion showed a significant relation with distant metastasis (P = 0.017). Stage IIB showed more recurrences, 33% (7/21). There was a significant different 5-year disease specific survival for stage IIA and IIB, respectively, 95% and 74% (P = 0.0311). Patients with a differentiation grade 3 and stage IIB showed a significantly poorer (P = 0.003) 5-year survival of 48.6% (P = 0.003). Results obtained in the present series of patients are in accordance with the literature. The present treatment policy seems justified, except for patients with pathologic stage IIB and grade 3, in which a more aggressive treatment should be considered.

    Background Despite being one of the most common cancers, bladder cancer is largely inefficiently and inaccurately staged and monitored. Current imaging methods detect cancer only when it has reached “visible” size and has significantly disrupted the structure of the organ. By that time, thousands of cells will have proliferated and perhaps metastasized. Repeated biopsies and scans are necessary to determine the effect of therapy on cancer growth. In this report, we describe a novel approach b...

    Full Text Available Objective To evaluate the safety and efficacy of high intensity focused ultrasound for palliation of inoperable pancreatic cancer in humans. Patients Eighty-nine patients with advanced pancreatic cancer were treated with high intensity focused ultrasound. There were 4 patients with stage II, 39 patients with stage III, and 46 patients with stage IV disease. The location of the tumors was as follows: head of pancreas 34 patients, body and/or tail of pancreas 55 patients. Methods Pain relief, local tumor control rate, median survival and complications were observed after high intensity focused ultrasound treatment. Results In the clinical treatments in humans the following local tumor control was seen: complete response, 0%; partial response, 14.6%; no change, 57.3%; progressive disease, 28.1%. Pain relief was achieved in 80.6% of patients who had pain prior to high intensity focused ultrasound therapy. The median survival was 26.0 months for patients with stage II disease, 11.2 months for patients with stage III disease, and 5.4 months for patients with stage IV disease. One-year survival rate was as follows: stage II, 100%; stage III, 41.0%; and stage IV, 6.5%. Twoyear survival rate was as follows: stage II, 75.0%; stage III, 10.3%; and stage IV, 0%. Complications included superficial skin burns (3.4%, subcutaneous fat sclerosis (6.7%, and an asymptomatic pancreatic pseudocyst (1.1%. There were no severe complications or adverse events related to high intensity focused ultrasound therapy seen in any of the patients treated. Conclusions Although this retrospective study has significant limitations, preliminary results suggest that the clinical application of high intensity focused ultrasound for pancreatic cancer appears to be safe and is a promising modality of treatment for palliation of pain related to pancreatic cancer.

    Flavonoids are natural antioxidants found in various foods, and a major source is black tea. Some experimental evidence indicates that flavonoids could prevent prostate cancer. We investigated the associations between flavonoid intake, black tea consumption, and prostate cancer risk in the Netherlands Cohort study, which includes 58,279 men who provided detailed baseline information on several cancer risk factors. From 1986 to 2003, 3,362 prostate cancers were identified, including 1,164 advanced (stage III/IV) cancers. Cox proportional hazards regression using the case-cohort approach was used to estimate hazard ratios and 95% confidence intervals. Intake of total catechin, epicatechin, kaempferol, and myricetin and consumption of black tea were associated with a decreased risk of stage III/IV or stage IV prostate cancer. Hazard ratios of stage III/IV and stage IV prostate cancer for the highest versus the lowest category of black tea consumption (≥5 versus ≤1 cups/day) were 0.75 (95% confidence interval: 0.59, 0.97) and 0.67 (95% confidence interval: 0.50, 0.91), respectively. No associations were observed for overall and nonadvanced prostate cancer. In conclusion, dietary flavonoid intake and black tea consumption were associated with a decreased risk of advanced stage prostate cancer.

    AIM: To compare the accuracy of hydrocolonic sonography (HUS) in determining the depth of invasion (T stage) in colon and rectal cancer.METHODS: A total of 1 000-2 000 mL of saline was instilled per rectum using a system for barium enemas, and then ultrasonography was conducted by a SSA-270A (Toshiba Co, Japan) sonolayer unit with a 3.75 MHz for 17 patients with colon cancer and 13 patients with rectal cancer before operation. After operation, T stage in HUS was compared with postoperative histological findings.RESULTS: Overall, the accuracy of T stage was 70%. It was 88% in colon cancer and 46% in rectal cancer. In evaluating nodal state, the accuracy of HUS was low in both colon (71%) and rectal cancers (46%) compared with conventional CT or MRI. The overall accuracy of N staging was 60%.CONCLUSION: HUS is valuable to evaluate the depth of invasion in colon cancer, but is less valuable in rectal cancer. Because HUS is low-cost, noninvasive, and readily available at any place, this technique seems to be useful to determine the preoperative staging in colon cancer, but not in rectal cancer.

    This trial was designed to compare the efficacy and safety between epirubicin (E) and carboplatin (C) in combination with paclitaxel (P) and trastuzumab (H) in neoadjuvant setting. In 13 Chinese cancer centers, 100 patients with HER2-positive, locally advanced breast cancer were 1:1 randomized to receive medication as follows: trastuzumab and paclitaxel weekly combined with carboplatin weekly for PCH group, or epirubicin every 3 weeks for PEH group. Patients were given 4 to 6 cycles of chemotherapy. The primary endpoint was pathologic complete response (pCR) rate, which was no significant difference in PCH and PEH regimen (39.1% vs. 48.8%; p=0.365). However, PEH regimen achieved higher pCR in luminal-B (HER2-poitive) subgroup (55.0% vs. 24.0%; p = 0.033), but not in ERBB2+ subgroup (42.9% vs. 57.1%; p = 0.355). PEH regimen showed a favorable efficacy in PIK3CA mutated subgroup (69.2% vs.23.5%, p=0.012). No significant difference was observed in the subgroup analysis of TP53 mutation status, PTEN expression, FCGR2A SNP and FCGR3A SNP. Both regimens as neoadjuvant chemotherapy achieve similar efficacy and safety. PEH might improve pCR rate, especially in the luminal-B subtype and PIK3CA mutation subtype. PEH is feasible and less likely to increase the incidence of acute cardiac events compared to PCH. PMID:26084292

  6. Choline PET and PET/CT in Primary Diagnosis and Staging of Prostate Cancer

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available PET and PET/CT using [11C]- and [18F]-labelled choline derivates is increasingly being used for imaging of primary and recurrent prostate cancer. While PET and PET/CT with [11C]- and [18F]-labelled choline derivates in patients suffering from biochemical recurrence of prostate cancer has been examined in many studies that demonstrate an increasing importance, its role in the primary staging of prostate cancer is still a matter of debate.Morphological and functional imaging techniques such as CT, MRI and TRUS have demonstrated only limited accuracy for the diagnosis of primary prostate cancer. Molecular imaging with PET and PET/CT could potentially increase accuracy to localize primary prostate cancer. A considerable number of studies have examined the value of PET/CT with [11C]- and [18F]- labelled choline derivates for the diagnosis of primary prostate cancer with mixed results. Primary prostate cancer can only be detected with moderate sensitivity using [11C]- and [18F]choline PET and PET/CT. The detection rate depends on the tumour configuration. Detection is also limited by a considerable number of microcarcinomas that cannot be detected due to partial volume effects. Therefore small and in part rind-like tumours can often not be visualized. Furthermore, the differentiation between benign changes like prostatitis, high-grade intraepithelial neoplasia (HGPIN or prostatic hyperplasia is not always possible. Therefore, at the present time, the routine use of PET/CT with [11C]- and [18F]-labelled choline derivates cannot be recommended as a first-line screening procedure for primary prostate cancer in men at risk. A potential application of choline PET and PET/CT may be to increase the detection rate of clinically suspected prostate cancer with multiple negative prostate biopsies, for example in preparation of a focused re-biopsy and may play a role in patient stratification with respect to primary surgery and radiation therapy in the future.

  9. Role of Postmastectomy Radiation After Neoadjuvant Chemotherapy in Stage II-III Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To identify a cohort of women treated with neoadjuvant chemotherapy and mastectomy for whom postmastectomy radiation therapy (PMRT) may be omitted according to the projected risk of local-regional failure (LRF). Methods and Materials: Seven breast cancer physicians from University of California cancer centers created 14 hypothetical clinical case scenarios, identified, reviewed, and abstracted the available literature (MEDLINE and Cochrane databases), and formulated evidence tables with endpoints of LRF, disease-free survival, and overall survival. Using the American College of Radiology appropriateness criteria methodology, appropriateness ratings for postmastectomy radiation were assigned for each scenario. Finally, an overall summary risk assessment table was developed. Results: Of 24 sources identified, 23 were retrospective studies from single institutions. Consensus on the appropriateness rating, defined as 80% agreement in a category, was achieved for 86% of the cases. Distinct LRF risk categories emerged. Clinical stage II (T1-2N0-1) patients, aged >40 years, estrogen receptor-positive subtype, with pathologic complete response or 0-3 positive nodes without lymphovascular invasion or extracapsular extension, were identified as having ≤10% risk of LRF without radiation. Limited data support stage IIIA patients with pathologic complete response as being low risk. Conclusions: In the absence of randomized trial results, existing data can be used to guide the use of PMRT in the neoadjuvant chemotherapy setting. Using available studies to inform appropriateness ratings for clinical scenarios, we found a high concordance of treatment recommendations for PMRT and were able to identify a cohort of women with a low risk of LRF without radiation. These low-risk patients will form the basis for future planned studies within University of California Athena Breast Health Network.

    Pancreas cancer, or pancreatic ductal adenocarcinoma, is the deadliest of solid tumors, with a five-year survival rate of disease improves survival rates, but access to tissue and other biospecimens that could be used to develop early detection markers is confounded by the insidious nature of pancreas cancer. Mouse models that accurately recapitulate the human condition allow disease tracking from inception to invasion and can therefore be useful for studying early disease stages in which surgical resection is possible. Using a highly faithful mouse model of pancreas cancer in conjunction with a high-density antibody microarray containing ∼2500 antibodies, we interrogated the pancreatic tissue proteome at preinvasive and invasive stages of disease. The goal was to discover early stage tissue markers of pancreas cancer and follow them through histologically defined stages of disease using cohorts of mice lacking overt clinical signs and symptoms and those with end-stage metastatic disease, respectively. A panel of seven up-regulated proteins distinguishing pancreas cancer from normal pancreas was validated, and their levels were assessed in tissues collected at preinvasive, early invasive, and moribund stages of disease. Six of the seven markers also differentiated pancreas cancer from an experimental model of chronic pancreatitis. The levels of serine/threonine stress kinase 4 (STK4) increased between preinvasive and invasive stages, suggesting its potential as a tissue biomarker, and perhaps its involvement in progression from precursor pancreatic intraepithelial neoplasia to pancreatic ductal adenocarcinoma. Immunohistochemistry of STK4 at different stages of disease revealed a dynamic expression pattern further implicating it in early tumorigenic events. Immunohistochemistry of a panel of human pancreas cancers confirmed that STK4 levels were increased in tumor epithelia relative to normal tissue. Overall, this integrated approach yielded several tissue

    Full Text Available Background: The clinical relevance of bone marrow micrometastasis (BMM in non-small-cell lung cancer is undetermined, and the value of such analyses in advanced stage patients has not been clearly assessed previously. This study was conducted to estimate the accuracy of both polymerase chain reaction (PCR and immunohistochemistry (IHC in micrometastases detection and determine the best site for bone marrow biopsy in order to find micrometastasis. Methods: This prospective cross-sectional study was performed in the Department of Thoracic Surgery, Alzahra University Hospital from September 2008 to June 2009. To evaluate the bone marrow, a 3-cm rib segment and an aspirated specimen from the iliac bone prior to tumor resection were taken. PCR and IHC were performed for each specimen to find micrometastasis. Results: Of 41 patients, 14 (34% were positive for BMM by PCR compared with two positive IHC (4.8%. All BMMs were diagnosed in rib segments, and iliac specimens were all free from metastatic lesion. Our data showed no significant association between variables such as age, sex, histology, tumor location, side of tumor, involved lobe, smoking, or weight loss and presence of BMM. Conclusion: PCR could use as a promising method for BMM detection. BMM in a sanctuary site (rib is not associated with advanced stages of lung cancer. In addition, when predictor variables such as age, sex, histology, tumor location, smoking, or weight loss are analyzed, no correlation can be found between micrometastasis prevalence and any of those variables.

In this study, the cancer preventive effects of Tahitian noni® juice (TNJ at the initiation stage on DMBA-induced mammary tumorigenesis in female SD rats was investigated.Objective: We took advantage of the DMBA-induced mammary carcinogenic model to study the preventive effects of TNJ at the initiation stage of mammary carcinogenesis in female SD rats by using clinical observation, pathological examination, and 32P-postlabeling assay.Methods: One hundred and sixty female SD rats were divided into eight groups with 20 rats in each group. Three doses of TNJ or placebo was given to the animals at the age of 35 days until the end of the experiment. When the animals were 55 days old, 25 mg/kg DMBA was fed to the animals in the DMBA group, placebo, and TNJ groups. The 20 rats were kept at age-matched controls. Palpable tumors were examined twice a week after DMBA administration in each group by an experienced professional. The size of tumor was measured by a graduated caliper. A piece of tumor, vascularization area, and mammary glands in the thoracic and abdomen areas of each rat were dissected respectively and fixed in 10% neutral buffered formalin for light microscope examination. The DMBA-DNA adduct formation in mammary tissues was detected by 32P-postlabeling assay.Results: The tumor latency in TNJ groups was delayed about 60-90 days when compared with positive controls. The number of palpable tumors per group was significantly reduced by 73%, 72% and 80% in 3%, 5%, and 10% TNJ groups respectively when compared with positive controls at the end of 330 days after DMBA administration. The number of palpable tumors in the placebo groups was slightly reduced in the early stage, but much less than that in the TNJ groups. The multiplicity and malignancy of lesions were significantly reduced and the survival rate of animals in the TNJ groups was

    Full Text Available Abstract Background The advent of prostate specific antigen (PSA testing in the United States of America (USA has led to a dramatic increase in the incidence of prostate cancer in the United States as well as the number of men undergoing aggressive treatment with radical prostatectomy and radiation therapy. We compared patient characteristics and treatment selection between American men with screening-detected versus clinically diagnosed prostate cancers. Methods We evaluated 3,173 men with prostate cancer in the USA. Surveys and medical records provided information on demographics, socioeconomic status, comorbidities, symptoms, tumor characteristics, and treatment. We classified men presenting with symptoms of advanced cancer – bone pain, weight loss, or hematuria – as "clinically diagnosed"; asymptomatic men and those with only lower urinary tract symptoms were considered "screening-detected." We used multivariate analyses to determine whether screening predicted receiving aggressive treatment for a clinically localized cancer. Results We classified 11% of cancers as being clinically diagnosed. Men with screening-detected cancers were more often non-Hispanic white (77% vs. 65%, P Conclusion Most cancers were detected by screening in this American cohort. Appropriately, younger, healthier men were more likely to be diagnosed by screening. Minority status and lower socio-economic status appeared to be screening barriers. Screening detected earlier-stage cancers and was associated with receiving aggressive treatment.

    2000-01-01

    The relationship between the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) and the clinical stages in gastric cancers was studied. By using terminal deoxynucleotidyl transferase-mediated nick end labelling (TUNEL) technique and PCNA immunohistochemical staining, the apoptosis and the expression of PCNA in tissue of gastric carcinoma were assayed in situ, the index of apoptosis (AI), index of PCNA (PI) and the rate of AI/PI were calculated. AI and PI in gastric cancer tissues were (6.5±3.7) % and (49.8±15.9) % respectively, and the rate of AI/PI was 0.13±0.05, which were obviously different from those of normal gastric mucosa in paragastric cancer (P<0.01). With the advanced TNM stages of gastric carcinoma, the AI was decreased, PI was increased and the rate of AI/PI decreased in gastric carcinoma. There was significant difference in them between the gastric cancer tissues and normal gastric mucosa in pericarcinoma in TNM stage Ⅱ to Ⅳ (P<0.05). It was suggested that the decreased apoptotic cells and the increased proliferating cells were obviously related to the tumor genesis and tumor progression in gastric carcinoma. The AI, PI and the rate of AI/PI would become the prognostic factors in advanced gastric carcinoma.

    2016-04-15

    Preclinical modelling studies are beginning to aid development of therapies targeted against key regulators of pancreatic cancer progression. Pancreatic cancer is an aggressive, stromally-rich tumor, from which few people survive. Within the tumor microenvironment cellular and extracellular components exist, shielding tumor cells from immune cell clearance, and chemotherapy, enhancing progression of the disease. The cellular component of this microenvironment consists mainly of stellate cells and inflammatory cells. New findings suggest that manipulation of the cellular component of the tumor microenvironment is possible to promote immune cell killing of tumor cells. Here we explore possible immunogenic therapeutic strategies. Additionally extracellular stromal elements play a key role in protecting tumor cells from chemotherapies targeted at the pancreas. We describe the experimental findings and the pitfalls associated with translation of stromally targeted therapies to clinical trial. Finally, we discuss the key inflammatory signal transducers activated subsequent to driver mutations in oncogenic Kras in pancreatic cancer. We present the preclinical findings that have led to successful early trials of STAT3 inhibitors in pancreatic adenocarcinoma. PMID:27096033

    Objective: To study the factors affecting post-operative staging and survival in non-small cell lung cancer (NSCLC) patients based on the revised TNM staging system adopted by the UICC in 1977. Methods: Data were collected from 1757 consecutively operated NSCLC patients, including those receiving complete tumor excision, tumor debulking and exploratory thoractomy from April 1969 through Dec. 1993. the end point of follow-up was Nov. 30, 1998. Cumulative survival and its influencing factors were analyzed by Kaplan-Meier and Cox model of SPSS software. Results: In this series, 30 patients (1.7%) were lost from follow-up. The 5-year cumulative survival was 88.0% for patients in stage I A, and 53.9% in stage IB, 33.5% in stage II, 14.7% in stage IIIA, 5.5% in stage IIIB and 7.0% in stage IV. The overall 5-year survival rate was 28.2%. The 5-year survivals were 39.8%, 14.4% and 4.2% in patients treated with completely tumor resection, tumor debulking and explorative thoractomy, respectively. The 10-year survival rate was 31.4%, 9.5% and 0, respectively. Factors affecting long-term cumulative survival, in the order of decreasing significance, were the type of operation, lymph node status, staging, size and pathological type of the primary tumor. Conclusion: the revised staging system for NSCLC is superior to that used since 1986 as far as the end results of treatment in patients in different stage and the staging specificity are concerned. The T3N1M0 classification and the definition of M1 need to be further studied.

    Full Text Available Objective. To determine the influence of comorbidity on survival in early-stage lung cancer patients treated with proton radiotherapy, using the Charlson Comorbidity Index. Study Design and Setting. Fifty-four non-small-cell lung cancer patients, treated prospectively in a phase II clinical trial with hypofractionated proton therapy, were analyzed retrospectively to assess their burden of comorbid disease as expressed by Charlson Comorbidity Index. Using the Charlson Comorbidity Index method, a predicted survival curve based on comorbidity was formulated and compared to the observed mortality from causes other than lung cancer in the study population. Results. The study population had an average age score of 2.8 and an average Charlson Comorbidity Index of 4.7. Predicted survival was calculated to be 67% and 50% at 2 and 4 years, respectively. Actual comorbidity-specific survival at 2 and 4 years was 64% and 45%, respectively. The observed survival fell within the 95% confidence intervals of the predicted survival at all time points up to 5 years. Conclusion. Predicted mortality from concurrent disease, based on Charlson Comorbidity Index, correlated well with observed comorbidity-specific mortality. This helps substantiate the accuracy of the data coding in cause of death and strengthens previously reported disease-specific survival rates.

    Full Text Available Problem: In 2009, breast cancer was the most common cancer in women, and colorectal cancer was the third most common cancer in both men and women. Currently, the majority of colorectal and almost 1/3 of breast cancers are diagnosed at an advanced stage in the US, which results in higher morbidity and mortality than would obtain with earlier detection. The incidence of late-stage cancer diagnoses varies considerably across the US, and few analyses have examined the entire US.Purpose: Using the newly available US Cancer Statistics database representing 98% of the US population, we perform multilevel analysis of the incidence of late-stage cancer diagnoses and translate the findings via bivariate mapping, answering questions related to both Why and Where demographic and geographic disparities in these diagnoses are observed.Methods: To answer questions related to Why disparities are observed, we utilize a three-level, random-intercepts model including person-, local area-, and region- specific levels of influence. To answer questions related to Where disparities are observed, we generate county level robust predictions of late-stage cancer diagnosis rates and map them, contrasting counties ranked in the upper and lower quantiles of all county predicted rates. Bivariate maps are used to spatially translate the geographic variation among US counties in the distribution of both BC and CRC late-stage diagnoses.Conclusions: Empirical modeling results show demographic disparities, while the spatial translation of empirical results shows geographic disparities that may be quite useful for state cancer control planning. Late stage BC and CRC diagnosis rates are not spatially random, manifesting as place-specific patterns that compare counties in individual states to counties across all states. Providing a relative comparison that enables assessment of how results in one state compare with others, this paper is to be disseminated to all state cancer control

    Abstract Background Missing data on tumour stage information is a common problem in population-based cancer registries. Statistical analyses on the level of tumour stage may be biased, if no adequate method for handling of missing data is applied. In order to determine a useful way to treat missing data on tumour stage, we examined different imputation models for multiple imputation with chained equations for analysing the stage-specific numbers of cases of malignant melanoma and female breas...

    Stereotactic body radiotherapy (SBRT) represents a consolidated treatment option for patients with medically inoperable early stage non-small cell lung cancer (NSCLC). The clinical evidence accumulated in the past decade supports its use as an alternative to surgery with comparable survival outcomes. Due to its limited toxicity, SBRT is also applicable to elderly patients with very poor baseline pulmonary function or other severe comorbidities. Recent comparative studies in operable patients raised the issue of the possible use of SBRT also for this subgroup, with quite promising results that still should be fully confirmed by prospective trials with long-term follow-up. Aim of this review is to summarize and discuss the major studies conducted over the years on SBRT and to provide data on the efficacy and toxicity of this radiotherapy technique for stage I NSCLC. Technical aspects and quality of life related issues are also discussed, with the goal to provide information on the current role and limitations of SBRT in clinical practice.

    Full Text Available IntroductionThe reported estimates of the economic costs associated with prostate cancer screening, diagnostic testing, and clinical staging are substantial. However, the resource costs (i.e., factors such as physician’s time, laboratory tests, patient’s time away from work included in these estimates are unknown. We examined the resource costs for prostate cancer screening, diagnostic tests, and staging; examined how these costs differ in the United States from costs in other industrialized countries; and estimated the cost per man screened for prostate cancer, per man given a diagnostic test, and per man given a clinically staged diagnosis of this disease.Methods We searched the electronic databases MEDLINE, EMBASE, and CINAHL for articles and reports on prostate cancer published from January 1980 through December 2003. Studies were selected according to the following criteria: the article was published in English; the full text was available for review; the study reported the resource or input cost data used to estimate the cost of prostate cancer testing, diagnosing, or clinical staging; and the study was conducted in an established market economy. We used descriptive statistics, weighted mean, and Monte Carlo simulation methods to pool and analyze the abstracted data.Results Of 262 studies examined, 28 met our selection criteria (15 from the United States and 13 from other industrialized countries. For studies conducted in the United States, the pooled baseline resource cost was $37.23 for screening with prostate-specific antigen (PSA and $31.77 for screening with digital rectal examination (DRE. For studies conducted in other industrialized countries, the pooled baseline resource cost was $30.92 for screening with PSA and $33.54 for DRE. For diagnostic and staging methods, the variation in the resource costs between the United States and other industrialized countries was mixed.Conclusion Because national health resources are limited

  3. MRI in T staging of rectal cancer: How effective is it?

    International Nuclear Information System (INIS)

    Rectal cancer constitutes about one-third of all gastrointestinal (GI) tract tumors. Because of the high recurrence rates (30%) in rectal cancer, it is vitally important to accurately stage these tumours preoperatively so that appropriate surgical resection can be undertaken. MRI is the ideal technique for the preoperative staging of these tumours. To determine the accuracy of local T staging of rectal cancer with MRI, using histopathological staging as the gold. Forty consecutive patients admitted with rectal cancer over a period of 18 months were included in this retrospective study. MRI scans were performed prior to surgery in all patients, on 1.5T scanners. Two radiologists, with a special interest in gastrointestinal imaging reported all images. Two dedicated histopathologists reported the histology slides. The accuracy of preoperative local MRI T staging was assessed by comparison with postoperative histopathological staging. There was agreement between MRI and histopathology (TNM) staging in 12 patients (30%). The sensitivity and specificity of MRI for T staging was 89% and 67% respectively. The circumferential resection margin (CRM) status was accurately staged in 94.1% of the patients. Preoperative staging with MRI is sensitive in identifying CRM involvement, which is the main factor affecting the outcome of surgery

    Full Text Available Breast cancer is one of the leading causes of death in the Philippines. One out of four who are diagnosed with breast cancer die within the first five years, and no less than 40 percent die within 10 years and it has continous rise as time passes by. Therefore, it is very important to know the factors that can help for the survival rate of the patients. The purpose of this study is to identify the best possible treatment or combination of treatments. The researchers considered four independent variables namely: Completed Surgery, Completed Chemotherapy, Completed Hormonotherapy and Completed Radiotherapy. The researchers limit this study for only 160 patients with stage 2 and 135 with stage 3 for a total of 295 patients considering the data gathered from three hospitals from Metro Manila. The names of the hospitals were not declared due to confidentiality of data. In identifying the best treatment or combination of treatments, odds, probabilities and odds ratios of patients, Logistic Regression Analysis was used.

    Magnetic resonance imaging (MRI) was performed in 62 patients with uterine cervical cancer and the preoperative MRI findings were compared with the pathological findings following surgery. The surgical stages of 62 patients were 2 at stage 0, 18 at stage Ia, 19 at stage Ib, 9 at stage IIa, 11 at stage IIb, 2 at stage IIIa, and 1 at stage IIIb. The MRI findings in the present study included: (1) the existence of a high intensity area (HIA) in the uterine cervix or minimum thickness of residual normal cervical tissue, (2) necrotic cavity, (3) pyometra, (4) irregular margin of the cervix, (5) parametrial invasion, (6) vaginal invasion, (7) bladder invasion, and (8) lymph node enlargement. No HIA was observed in any patient with stage 0 or stage Ia, in 8 patients with stage Ib, and in 2 patients with stage IIa, while all patients with cancer tissues greater than 10 mm in diameter had a HIA. In 39 patients in whom hysterectomy was undergone without conization, the findings of MRI correlated significantly (r=0.929, p<0.001) with the minimum thickness of residual normal cervical tissue by the pathological measurement. When the irregular margin of the cervix was regarded as a disruption of the cervical myo-metrium by cancer tissue, accuracy was 87%. Furthermore, the degrees of accuracy for parametrial invasion, vaginal invasion and bladder invasion were 92%, 90% and 94%, respectively. When lymphnodes greater than 15 mm in diameter were regarded as a positive in MRI, accuracy was 88%. The present results indicate that MRI is clinically effective in preoperatively evaluating the extension of uterine cervical cancer. (author).

    We extend a prior analysis on the relation between poverty and cancer incidence in a sample of 2.90 million cancers diagnosed in 16 US states plus Los Angeles over the 2005-2009 period by additionally considering stage at diagnosis. Recognizing that higher relative disparities are often found among less-common cancer sites, our analysis incorporated both relative and absolute measures of disparities. Fourteen of the 21 cancer sites analyzed were found to have significant variation by stage; in each instance, diagnosis at distant stage was more likely among residents of high-poverty areas. If the incidence rates found in the lowest-poverty areas for these 21 cancer sites were applied to the entire country, 18,000 fewer distant-stage diagnoses per year would be expected, a reduction of 8%. Conversely, 49,000 additional local-stage diagnoses per year would be expected, an increase of 4%. These figures, strongly influenced by the most common sites of prostate and female breast, speak to the trade-offs inherent in cancer screening. Integrating the type of analysis presented here into routine cancer surveillance activities would permit a more complete understanding of the dynamic nature of the relationship between socioeconomic status and cancer incidence.

    Colorectal cancer (CRC) is a major health problem worldwide accounting for over a million deaths annually. While many patients with Stage II and III CRC can be cured with combinations of surgery, radiotherapy and chemotherapy, this is morbid costly treatment and a significant proportion will suffer recurrence and eventually die of CRC. Increased understanding of the molecular pathogenesis of CRC has the potential to identify high risk patients and target therapy more appropriately. Despite increased understanding of the molecular events underlying CRC development, established molecular techniques have only produced a limited number of biomarkers suitable for use in routine clinical practice to predict risk, prognosis and response to treatment. Recent rapid technological developments, however, have made genomic sequencing of CRC more economical and efficient, creating potential for the discovery of genetic biomarkers that have greater diagnostic, prognostic and therapeutic capabilities for the management of CRC. This paper reviews the current understanding of the molecular pathogenesis of CRC, and summarizes molecular biomarkers that surgeons will encounter in current clinical use as well as those under development in clinical and preclinical trials. New molecular technologies are reviewed together with their potential impact on the understanding of the molecular pathogenesis of CRC and their potential clinical utility in classification, diagnosis, prognosis and targeting of therapy.

  9. 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.)

  11. Prognosis for Mammographically Occult, Early-Stage Breast Cancer Patients Treated With Breast-Conservation Therapy

    International Nuclear Information System (INIS)

    Purpose: To compare mammographically occult (MamOcc) and mammographically positive (MamPos) early-stage breast cancer patients treated with breast-conservation therapy (BCT), to analyze differences between the two cohorts. Methods and Materials: Our two cohorts consisted of 214 MamOcc and 2168 MamPos patients treated with BCT. Chart reviews were conducted to assess mammogram reports and method of detection. All clinical-pathologic and outcome parameters were analyzed to detect differences between the two cohorts. Results: Median follow-up was 7 years. There were no differences in final margins, T stage, nodal status, estrogen/progesterone receptor status, or 'triple-negative' status. Significant differences included younger age at diagnosis (p o histology (p < 0.0001). At 10 years, the differences in overall survival, cause-specific survival, and distant relapse between the two groups did not differ significantly. The MamOcc cohort had more breast relapses (15% vs. 8%; p = 0.0357), but on multivariate analysis this difference was not significant (hazard ratio 1.0, 95% confidence interval 0.993-1.007, p = 0.9296). Breast relapses were mammographically occult in 32% of the MamOcc and 12% of the MamPos cohorts (p = 0.0136). Conclusions: Although our study suggests that there are clinical-pathologic variations for the MamOcc cohort vs. MamPos patients that may ultimately affect management, breast relapse after BCT was not significantly different. Breast recurrences were more often mammographically occult in the MamOcc cohort; consideration should be given to closer follow-up and alternative imaging strategies (ultrasound, breast MRI) for routine posttreatment examination. To our knowledge, this represents the largest series addressing the prognostic significance of MamOcc cancers treated with BCT.

    The most well-characterized mechanism of multidrug resistance (MDR) involves P-glycoprotein (Pgp), a transmembrane protein acting as an ATP-dependent drug efflux pump. The recognition of {sup 9}9mTc-Sestamibi and other lipophilic cations as transport substrates for Pgp provided the necessary tool for the clinical assessment of Pgp function in patients with cancer. Many clinical studies from different institutions and trials including variety of malignancies indicate that both tumor uptake and clearance of {sup 9}9mTc-Sestamibi are correlate with Pgp expression and may be used for the phenotypic assessment of multidrug resistance. Although both parameters may predict tumor responsible to chemotherapy, the extraction of efflux rate constants appeared o provide a more direct index of Pgp function as compared tp tracer uptake ratio allowing to trace a continuous spectrum of drug transport activity. Preliminary studies the use of MDR imaging agents to monitor the modulating ability of revertant compounds. Although the results support the feasibility of this approach, the alteration of tracer pharmacokinetics induced by the modulators certainly constitute a challenge in the development of a simple functional test suitable in clinical practice. The extension of the acquired imaging methodology to tumors with redundant intrinsic resistant mechanism. Due to multifactorial nature of phenomenon, the development of new tracers with substrate specificity for other known the complex array of cellular mechanisms contributing to treatment failure.

  14. Intra-tumour signalling entropy determines clinical outcome in breast and lung cancer.

    2015-03-01

    Full Text Available The cancer stem cell hypothesis, that a small population of tumour cells are responsible for tumorigenesis and cancer progression, is becoming widely accepted and recent evidence has suggested a prognostic and predictive role for such cells. Intra-tumour heterogeneity, the diversity of the cancer cell population within the tumour of an individual patient, is related to cancer stem cells and is also considered a potential prognostic indicator in oncology. The measurement of cancer stem cell abundance and intra-tumour heterogeneity in a clinically relevant manner however, currently presents a challenge. Here we propose signalling entropy, a measure of signalling pathway promiscuity derived from a sample's genome-wide gene expression profile, as an estimate of the stemness of a tumour sample. By considering over 500 mixtures of diverse cellular expression profiles, we reveal that signalling entropy also associates with intra-tumour heterogeneity. By analysing 3668 breast cancer and 1692 lung adenocarcinoma samples, we further demonstrate that signalling entropy correlates negatively with survival, outperforming leading clinical gene expression based prognostic tools. Signalling entropy is found to be a general prognostic measure, valid in different breast cancer clinical subgroups, as well as within stage I lung adenocarcinoma. We find that its prognostic power is driven by genes involved in cancer stem cells and treatment resistance. In summary, by approximating both stemness and intra-tumour heterogeneity, signalling entropy provides a powerful prognostic measure across different epithelial cancers.

  15. Stage distribution of breast cancer diagnosed before and after implementation of population-based mammographic screening

    International Nuclear Information System (INIS)

    Purpose: The German mammographic screening program is very similar to the Norwegian Breast Cancer Screening Program (NBCSP), which started about 10 years earlier. This study analyzes the stage distribution of invasive breast cancers diagnosed in the pre-screening and screening period, and evaluates the overall mortality in women aged 55 - 74 in the pilot and non-pilot counties of the NBCSP. Materials and Methods: The NBCSP invites women aged 50 - 69 to participate in two-view mammography biennially. Chi-square statistics were used to compare percentages of the stage and treatment of invasive breast cancers diagnosed in women residing in the four pilot counties in the pre-screening (1984 - 1995) and screening (1996 - 2007) period. An ecological approach was used to analyze the age-specific mortality in the pilot and non-pilot counties for the period 1970 - 2007. Results: 50 % of the breast cancers diagnosed in the pre-screening period, 70 % of the cases detected with screening, 43 % of the interval cancers, and 52 % of the cancers diagnosed outside the NBCSP were stage I. Stage III + was present in 11 % of the cancers in the pre-screening period, and in 1 % of the cancers detected with screening. In the screening period, the breast cancer mortality rate decreased substantially more in the pilot counties than in the non-pilot counties. Conclusion: The stage distribution of breast cancer diagnosed in the NBCSP is prognostically favorable compared to cancers diagnosed outside the screening program. The reduction in the breast cancer mortality rate was more pronounced in the four pilot counties compared to the non-pilot counties. It is necessary to evaluate the program based on individual data.

    Full Text Available Background: Around 30% of all stage II colon cancer patients will relapse and die of their disease. At present no objective parameters to identify high-risk stage II colon cancer patients, who will benefit from adjuvant chemotherapy, have been established. With traditional histopathological features definition of high-risk stage II colon cancer patients is inaccurate. Therefore more objective and robust markers for prediction of relapse are needed. DNA copy number aberrations have proven to be robust prognostic markers, but have not yet been investigated for this specific group of patients. The aim of the present study was to identify chromosomal aberrations that can predict relapse of tumor in patients with stage II colon cancer.

    Cancer-related fatigue is associated with lower health-related quality of life and the majority of breast cancer survivors experience persistent fatigue after finishing treatment. The present study examined age, cancer stage, sleep quality, and depressed mood as predictors of five dimensions of fatigue in seventy fatigued breast cancer survivors who no longer evidenced any signs of cancer and were finished with treatment. Discriminant function analyses were used to predict fatigue subgroup membership (higher, lower) from age, stage, mood, and sleep for five subtypes: General, Mental, Emotional, and Physical Fatigue, and Vigor. Significant discriminant functions were found for all subtypes. Findings suggest that age, staging, mood, and sleep are all important predictors, but there are differential relationships when subtypes of fatigue are considered. Given current limitations in treating fatigue directly, interventions targeting mood and sleep should be considered as alternate approaches to reduce fatigue. PMID:20205039
