    High spatial resolution of dynamic contrast-enhanced (DCE) MR imaging allows characterization of heterogenous tumor microenvironment. Our purpose was to determine which is the best advanced MR imaging protocol, focused on additional MR perfusion method, for predicting recurrent metastatic brain tumor following gamma-knife radiosurgery (GKRS). Seventy-two consecutive patients with post-GKRS metastatic brain tumor were enrolled. Two readers independently calculated the percentile histogram cutoffs for normalized cerebral blood volume (nCBV) from dynamic susceptibility contrast (DSC) imaging and initial area under the time signal-intensity curve (IAUC) from DCE imaging, respectively. Area under the receiver operating characteristic curve (AUC) and interreader agreement were assessed. For differentiating tumor recurrence from therapy effect, adding DCE imaging to diffusion-weighted imaging (DWI) significantly improved AUC from 0.79 to 0.95 for reader 1 and from 0.80 to 0.96 for reader 2, respectively. There was no significant difference of AUC between the combination of DWI with DSC imaging and the combination of DWI with DCE imaging for both readers. With the combination of DWI and DCE imaging, the sensitivity and specificity were 86.7 and 88.1 % for reader 1 and 90.0 and 85.7 % for reader 2, respectively. The intraclass correlation coefficient (ICC) between readers was highest for calculation of the 90th percentile histogram cutoffs for IAUC (ICC, 0.87). Adding perfusion MR imaging to DWI significantly improves the prediction of recurrent metastatic tumor; however, the diagnostic performance is not affected by selection of either DSC or DCE MR perfusion method.

    Background AT-101 is a BCL-2 Homolog domain 3 mimetic previously demonstrated to have tumoricidal effects in advanced solid organ malignancies. Given the evidence of activity in xenograft models, treatment with AT-101 in combination with docetaxel is a therapeutic doublet of interest in metastatic head and neck squamous cell carcinoma. Patients and Methods Patients included in this trial had unresectable, recurrent, or distantly metastatic head and neck squamous cell carcinoma (R/M HNSCC) not amenable to curative radiation or surgery. This was an open label randomized, phase II trial in which patients were administered AT-101 in addition to docetaxel. The three treatment arms were docetaxel, docetaxel plus pulse dose AT-101, and docetaxel plus metronomic dose AT-101. The primary endpoint of this trial was overall response rate. Results Thirty-five patients were registered and 32 were evaluable for treatment response. Doublet therapy with AT-101 and docetaxel was well tolerated with only 2 patients discontinuing therapy due to treatment related toxicities. The overall response rate was 11% (4 partial responses) with a clinical benefit rate of 74%. Median progression free survival was 4.3 months (range: 0.7–13.7) and overall survival was 5.5 months (range: 0.4–24). No significant differences were noted between dosing strategies. Conclusion Although met with a favorable toxicity profile, the addition of AT-101 to docetaxel in R/M HNSCC does not appear to demonstrate evidence of efficacy. PMID:27225873

    When metastatic or recurrent disease from colorectal carcinoma is detected, the surgeon must decide whether a patient is a candidate for resection. Although long-term survival after resection is not optimal, the relegation of patients to nonresective treatment means denying them the only chance for cure currently available. When isolated disease involving the liver, lung, or region of the primary carcinoma is documented, curative resection must be considered. Symptomatic patients may also obtain maximal palliation from resection, diversion, or a bypass procedure. Chemotherapy for the treatment of recurrent disease is palliative and probably should be considered only within clinical trials. Future alternative methods of treatment or new chemotherapeutic regimens need to be studied to improve survival and quality of life. PMID:8426994

    Acute kidney injury (AKI) is a rare complication of carcinoid syndrome. A 61-year-old man developed carcinoid syndrome 51 months after pneumonectomy for bronchial carcinoid, and 8 episodes of AKI 101 to 118 months after pneumonectomy. Serum chromogranin A and urine 5-hydroxyindoleacetic acid levels were elevated for more than 1 year before AKI occurred. Each episode was characterized by flushing, facial edema, mild diarrhea, necrosis of hepatic metastatic nodules, mild oliguria, hyponatremia, acidosis, hypokalemia, hypomagnesemia and hyperphosphatemia. He did not have elevated urine sodium levels or osmolality, hypotension or hypertension. Plasma levels of dopamine, epinephrine and norepinephrine, measured during a single episode, were markedly elevated. Serum creatinine levels returned to normal after most episodes. Hyponatremia persisted but was more severe during AKI. Elevated plasma levels of vasoactive substances other than 5-hydroxytryptamine, perhaps dopamine or other catecholamines, could explain recurrent AKI. The natriuretic effect of elevated plasma dopamine levels could explain chronic hyponatremia. PMID:22008780

    Hepatocellular carcinoma (HCC) is one of the most common malignancies in China. To date, surgery is still the best solution to it. However, metastatic recurrences after curative hepatic resections are very common. Tang et al have reported that recurrence rate within 5 years of curative hepatic resection is 61.5% [1]. As curative hepatic resection has a high tendency for metastatic recurrence, therapeutic interventions such as transarterial embolization and antiangiogenesis have been tried to further improve prognosis of HCC patients. Therefore, establishing a dependable, sensitive, easy, and economical method to predict metastatic recurrence following curative hepatic resection is of clinical urgency.

    Between 1986 and 1992, 10 patients (12 lesions) of advanced breast cancer were treated with multidisciplinary treatment including brachytherapy. The lesions treated included 5 primary breast tumors, 3 metastatic lesions in the contra lateral breast, 2 recurrences after external beam irradiation, 1 metastasis to the axillary lymph node and 1 metastasis to the upper arm skin. The interstitial irradiation techniques used were [sup 192]Ir low dose-rate irradiation for 5 lesions and high dose-rate for 7 lesions (including 3 with mould irradiation). External hyperthermia as performed for 6 lesions and interstitial hyperthermia were performed for 4 lesions. The local response was CR for 3 lesions, PRa for 8 lesions, PRb for 1 lesion with the local response rate being 100%. Excellent local control could be achieved by combination external and interstitial irradiation, indicating that radiotherapy is definitely useful for the treatment of advanced breast cancer.

  11. SR-1000 radiofrequency chemo-hyperthermia for recurrent and metastatic peritoneo-pelvic malignant tumors

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy and tolerance of intraperitoneal chemo-hyperthermia (IPCH) with SR-1000 radiofrequency (RF) for recurrent or metastatic peritoneo-pelvic malignant tumors. Methods: Twenty-one patients with recurrent or metastatic peritoneo-pelvic malignant tumors received chemo-hyperthermia, with 9 having local pain and 14 having ascites. The Karnofsky scores were 40-80. After abdominal cavity aspiration and infusion of hot NS and chemotherapeutic agents, the temperature of abdominal cavity was increased and maintained at 40.5-42.5 degree C for 60-90 minutes with SR-1000 RF. Hyperthermia was given twice per week and chemotherapy once per week, with the whole treatment lasting for 2-4 weeks. The commonly used drugs were DDP, MMC, 5-FU and so on. Results: Local pain was relieved in 8 of 9 patients, complete disappearance of ascites in 10 of 14. The common side-effects were fat necrosis (14.3%) and abdominal pain (24.8%). Conclusions: Intraperitoneal chemo-hyperthermia with SR-1000 RF appears to be a promising new approach for patients with recurrent or metastatic peritoneo-pelvic malignant tumors, especially for those who did not response to systemic chemotherapy or whose tumor recurred after chemotherapy. As to bulky lesions, local supplementary radiotherapy should be given in order to obtain better local control

    AIM: To analyze the local and systemic complications of high intensity focused ultrasound (HIFU) for patients with recurrent and metastatic abdominal tumors.METHODS: From Aug 2001 to Aug 2004, 17 patients with recurrent and metastatic abdominal tumors were enrolled in this study. Real-time sonography was taken, and vital signs, liver and kidney function, skin burns, local reactions, and systemic effects were observed and recored before, during, and after HIFU. CT and MRI were also taken before and after HIFU.RESULTS: All 17 patients had skin burns and pAln in the treatment region; the next common complication was neurapraxia of the stomach and intestines to variable degrees. The other local and systemic complications were relatively rare. Severe complications were present in two patients; one developed a superior mesenteric artery infarction resulting in necrosis of the entire small intestines, and the other one suffered from a perforation in terminal ileum due to HIFU treatment.CONCLUSION: Although HIFU is a one of noninvasive treatments for the recurrent and metastatic abdominal tumors, there are still some common and severe complications which need serious consideration.

  13. Class III β-tubulin is a predictive marker for taxane-based chemotherapy in recurrent and metastatic gastric cancer

    International Nuclear Information System (INIS)

    Class III β-tubulin (TUBB3) is a prognostic marker in various tumors, but the role of TUBB3 in advanced gastric cancer is not clearly defined. We analyzed the significance of TUBB3 expression, along with that of excision repair cross-complementation group 1 (ERCC1) in recurrent and metastatic gastric cancer patients receiving taxane-based first-line palliative chemotherapy. We reviewed the cases of 146 patients with advanced gastric adenocarcinoma who received taxane-based first-line palliative chemotherapy between 2004 and 2010 at Chonnam National University Hwasun Hospital (Gwangju, Korea). Immunohistochemical staining for TUBB3 and ERCC1 was performed using paraffin wax-embedded tumor tissues. We evaluated the patients’ response to chemotherapy, progression-free survival (PFS), and overall survival (OS). In total, 146 patients with advanced gastric cancer received docetaxel and cisplatin (n = 15) or paclitaxel and cisplatin (n = 131). The median PFS was significantly shorter for patients with high-level TUBB3 expression than for patients with low-level TUBB3 expression (3.63 vs. 6.67 months, P = 0.001). OS was not associated with TUBB3 expression (13.1 vs. 13.1 months, P = 0.769). By multivariate analysis, only TUBB3 was related to a shorter PFS (HR 2.74, 95% CI 1.91-3.91, P = 0.001). Patients with high-level ERCC1 expression showed a lower response rate than patients with low-level ERCC1 expression (24 vs. 63.2%, P = 0.001); however, ERCC1 had no clinical effect on PFS or OS. TUBB3 was a strong predictive marker in recurrent and metastatic gastric cancer patients receiving taxane-based first-line palliative chemotherapy. No clinical impact of ERCC1 was evident in this setting

  14. US-guided biopsy of nonpalpable recurrent or metastatic cervical thyroid malignancy

    International Nuclear Information System (INIS)

    In 16 patients with a history of thyroidectomy performed for malignancy, high-frequency (10-MHz) US-guided biopsy of nonpalpable, sonographically detected neck masses was performed. The masses biopsied ranged in size from 6 mm to 3 cm. Eleven biopsies were positive for neoplasm. All 11 patients underwent surgical exploration, and neoplasms were confirmed in ten. In five patients biopsies were negative for neoplasm, and no malignancy was found on subsequent follow-up. There were no biopsy complications. US-guided biopsy of nonpalpable, sonographically detected neck masses is an effective and safe technique for documenting or excluding recurrent or metastatic cervical thyroid malignancy

    Marrow ablative chemotherapy (MAC) with autologous hematopoietic stem cell transplantation (HSCT) is limited by poor bone marrow reserve after chemotherapy and/or radiotherapy, and the extent of bone/bone marrow disease. We report a child with recurrent metastatic medulloblastoma who received an allogeneic HSCT while in relapse and subsequently achieved radiological resolution of disease and favorable marrow minimal residual disease (MRD) response. Disease recurred intra-cranially at 304 days post-HSCT. Tumor biopsy 488 days post-HSCT showed infiltration with donor lymphocytes demonstrating graft-versus-tumor (GVT) effect. The patient remained alive >2 years post-HSCT. Allogeneic HSCT may be a consideration for high-risk recurrent medulloblastoma. PMID:25894457

    Background Human papillomavirus (HPV) tumor status and surgical salvage are associated with improved prognosis for patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC). Current data regarding types of surgery and the impact of surgery for distant metastatic disease are limited. Methods A retrospective analysis of patients with recurrent OPSCC from two institutions between 2000-2012 was performed. P16 immunohistochemistry and/or in situ hybridization, as clinically available, were used to determine HPV tumor status. Clinical characteristics, distribution of recurrence site and treatment modalities were compared by HPV tumor status. Overall survival was examined by Kaplan-Meier and Cox proportional hazards methods. Results The study included 108 patients with 65 locoregional and 43 distant metastatic first recurrences. The majority were HPV-positive (n=80). HPV-positive tumor status was associated with longer time to recurrence (p<0.01). Anatomic site distribution of recurrences did not differ by HPV tumor status. HPV-positive tumor status (adjusted HR [aHR] 0.23 (95%CI 0.09-0.58), p=0.002), longer time to recurrence (≥1 year; aHR 0.36 (0.18-0.74), p=0.006), and surgical salvage (aHR 0.26 (0.12-0.61), p=0.002) were independently associated with overall survival after recurrence. Surgical salvage was independently associated with improved overall survival compared to non-surgical treatment in both locoregional (aHR 0.15 (0.04-0.56), p=0.005) and distant metastatic recurrence (aHR 0.19 (0.05-0.75), p=0.018). Conclusions Surgical salvage is associated with improved overall survival for recurrent locoregional and distant metastatic OPSCC, independent of HPV tumor status. Further prospective data is needed to confirm the role of surgical salvage for distant metastases. PMID:25782027

  17. Bisphosphonate treatment of aggressive primary, recurrent and metastatic Giant Cell Tumour of Bone

    International Nuclear Information System (INIS)

    Giant cell tumour of bone (GCTB) is an expansile osteolytic tumour which contains numerous osteoclast-like giant cells. GCTB frequently recurs and can produce metastatic lesions in the lungs. Bisphosphonates are anti-resorptive drugs which act mainly on osteoclasts. In this study, we have examined clinical and radiological outcomes of treatment with aminobisphosphonates on 25 cases of aggressive primary, recurrent and metastatic GCTB derived from four European centres. We also analysed in vitro the inhibitory effect of zoledronic acid on osteoclasts isolated from GCTBs. Treatment protocols differed with several different aminobisphosphonates being employed, but stabilisation of disease was achieved in most of these cases which were refractory to conventional treatment. Most inoperable sacral/pelvic tumours did not increase in size and no further recurrence was seen in GCTBs that had repeatedly recurred in bone and soft tissues. Lung metastases did not increase in size or number following treatment. Zoledronic acid markedly inhibited lacunar resorption by GCTB-derived osteoclasts in vitro. Our findings suggest that bisphosphonates may be useful in controlling disease progression in GCTB and that these agents directly inhibit GCTB - derived osteoclast resorption. These studies highlight the need for the establishment of standardised protocols to assess the efficacy of bisphosphonate treatment of GCTB

    Full Text Available Background. Radiotherapy has been utilized for metastatic and recurrent osteosarcoma and Ewing sarcoma (ES, in order to provide palliation and possibly prolong overall or progression-free survival. Stereotactic body radiotherapy (SBRT is convenient for patients and offers the possibility of increased efficacy. We report our early institutional experience using SBRT for recurrent and metastatic osteosarcoma and Ewing sarcoma. Methods. We reviewed all cases of osteosarcoma or ES treated with SBRT between 2008 and 2012. Results. We identified 14 patients with a total of 27 lesions from osteosarcoma (n=19 or ES (n=8. The median total curative/definitive SBRT dose delivered was 40 Gy in 5 fractions (range, 30–60 Gy in 3–10 fractions. The median total palliative SBRT dose delivered was 40 Gy in 5 fractions (range, 16–50 Gy in 1–10 fractions. Two grade 2 and 1 grade 3 late toxicities occurred, consisting of myonecrosis, avascular necrosis with pathologic fracture, and sacral plexopathy. Toxicity was seen in the settings of concurrent chemotherapy and reirradiation. Conclusions. This descriptive report suggests that SBRT may be a feasible local treatment option for patients with osteosarcoma and ES. However, significant toxicity can result, and thus systematic study is warranted to clarify efficacy and characterize long-term toxicity.

    Indications for hormonotherapy in prostate cancer are in deep mutation and are constantly evolving. Used initially (1941) in metastatic stages, hormone therapy is used nowadays in locally advanced prostate cancer and aggressive localized disease. Its prescription in association with radiotherapy or surgery has provided a benefit regarding survival free progression. The place of hormone therapy in localized prostate cancer is not well defined and the debate is still ongoing, especially in case of biochemical recurrence after irradiation or radical prostatectomy and even in neoadjuvant cases. Additional and further studies are ongoing and are strongly needed to establish new guidelines. Nevertheless, hormone therapy is not restricted any more to palliative cases and is part of the current therapeutic arsenal of the urologist for high risk localized and/or locally advanced prostate cancers.

    Purpose: To evaluate the outcome of robotic CyberKnife (Accuray, Sunnyvale, CA)-based stereotactic radiotherapy (CBK-SRT) for isolated recurrent primary, lymph node, or metastatic prostate cancer. Methods and Materials: Between May 2007 and December 2009, 34 consecutive patients/38 lesions were treated (15 patients reirradiated for local recurrence [P], 4 patients reirradiated for anastomosis recurrence [A], 16 patients treated for single lymph node recurrence [LN], and 3 patients treated for single metastasis [M]). In all but 4 patients, [{sup 11}C]choline positron emission tomography/computed tomography was performed. CBK-SRT consisted of reirradiation and first radiotherapy in 27 and 11 lesions, respectively. The median CBK-SRT dose was 30 Gy in 4.5 fractions (P, 30 Gy in 5 fractions; A, 30 Gy in 5 fractions; LN, 33 Gy in 3 fractions; and M, 36 Gy in 3 fractions). In 18 patients (21 lesions) androgen deprivation was added to CBK-SRT (median duration, 16.6 months). Results: The median follow-up was 16.9 months. Acute toxicity included urinary events (3 Grade 1, 2 Grade 2, and 2 Grade 3 events) and rectal events (1 Grade 1 event). Late toxicity included urinary events (3 Grade 1, 2 Grade 2, and 2 Grade 3 events) and rectal events (1 Grade 1 event and 1 Grade 2 event). Biochemical response was observed in 32 of 38 evaluable lesions. Prostate-specific antigen stabilization was seen for 4 lesions, and in 2 cases prostate-specific antigen progression was reported. The 30-month progression-free survival rate was 42.6%. Disease progression was observed for 14 lesions (5, 2, 5, and 2 in Groups P, A, LN, and M respectively). In only 3 cases, in-field progression was seen. At the time of analysis (May 2010), 19 patients are alive with no evidence of disease and 15 are alive with disease. Conclusions: CyberKnife-based stereotactic radiotherapy is a feasible approach for isolated recurrent primary, lymph node, or metastatic prostate cancer, offering excellent in-field tumor

    The efficacy and tolerability of a combination of vincristine, cisplatin, teniposide, and cyclophosphamide (OPEC) in 11 patients (median age, 45 yr) with recurrent and/or metastatic adrenocortical cancer (ACC) (seven functional and four nonfunctional) were evaluated. All patients received this regimen after the failure of streptozocin and o,p'-DDD (SO) combination therapy. The regimen comprised cyclophosphamide, 600 mg/m2, and vincristine, 1.5 mg/m2, maximum dose 2.0 mg (d 1); cisplatin, 100 mg/m2 (d 2) and teniposide, 150 mg/m2 (d 4). Cycles were repeated every 4 wk. One to eight cycles (median, six cycles) of OPEC were administered to each patient. The median duration of treatment was 6 mo. The overall 2-yr survival rate was 82% and the median survival since diagnosis was 44 mo while it was 21 mo since start of OPEC therapy. Responses were obtained in nine patients: partial response in two patients, and stable disease in seven patients. The median duration of response was 6.75 mo. A total of 60 cycles of chemotherapy were given to all patients; grade 1-2 toxicity occurred in 57 cycles, while grade 3 toxicity was observed only in two cycles, according to NCI's Common Toxicity Criteria. We conclude that the OPEC regimen may be considered in recurrent or metastatic ACC as a second-line medical treatment. However, the combination is accompanied by considerable side effects and dose modifications are necessary in order to be able to recommend the treatment. This regimen needs further evaluation compared with SO therapy preferably in a randomized multicenter trial. PMID:15299189

Lapatinib is a potent dual inhibitor of HER-2 and EGFR. Preclinical and phase I studies have shown activity with lapatinib in a number of cancers, including breast cancer, and the drug is well tolerated. The main known drug interactions are with paclitaxel and irinotecan. The most significant side-effects of lapatinib are diarrhea and adverse skin events. Rates of cardiotoxicity compare favorably with trastuzumab, a monoclonal antibody against HER-2. This paper focuses on lapatinib in advanced and metastatic breast cancer, which remains an important therapeutic challenge. Phase II and III studies show activity as monotherapy, and in combination with chemotherapy or hormonal agents. Results from these studies suggest that the main benefit from lapatinib is in the HER-2 positive breast cancer population. Combinations of lapatinib and trastuzumab are also being studied and show encouraging results, particularly in trastuzumab-refractory metastatic breast cancer. Lapatinib may have a specific role in treating HER-2 positive CNS metastases. The role of lapatinib as neoadjuvant therapy and in early breast cancer is also being evaluated.Keywords: HER-2, EGFR, erbB, lapatinib, Tykerb®, tyrosine kinase

    The aim of the study was to assess the efficacy and toxicity of cetuximab in the combined treatment for patients with recurrent and/or metastatic nasopharyngeal carcinoma (R/M NPC). Between March 2007 and November 2011, a total of 30 R/M NPC patients treated with comprehensive therapy including cetuximab were retrospectively enrolled. Intensity-modulated radiation therapy was delivered in recurrent disease with a median dose of 60 Gy. Chemotherapy regimens included TP/TPF (docetaxel 60-75 mg/m d1+DDP 25 mg/m d1-3±5-FU 500 mg/m/day with 120-h infusion), GP (gemcitabine 1.0 g/m d1, d8+DDP 25 mg/m d1-3), and PC (paclitaxel 60 mg/m/week d1+carboplatin AUC 2/week d1). Acute and late toxicities were documented by the radiation oncologists. The median age of the patients was 44 years (range 26-62). A total of 21 patients (70%) achieved response (CR+PR). The median survival time, time to progression, and 2-year overall survival were 23.6, 12.2 months, and 53.3%, respectively. Cetuximab appears to be effective and well tolerated when combined with chemoradiation therapy for the treatment of R/M NPC. PMID:26352217

    Full Text Available We evaluate the outcomes of irradiation by using three-dimensional radiation therapy (3D-RT or intensity-modulated radiotherapy (IMRT for recurrent and metastatic cervical cancer. Between 2007 and 2010, 50 patients with recurrent and metastatic cervical cancer were treated using 3D-RT or IMRT. The median time interval between the initial treatment and the start of irradiation was 12 (6-51 months. Salvage surgery was performed before irradiation in 5 patients, and 38 patients received concurrent chemotherapy. Sixteen patients underwent 3D-RT, and 34 patients received IMRT. Median follow-up for all the patients was 18.3 months. Three-year overall survival and locoregional control were 56.1% and 59.7%, respectively. Three-year progression-free survival and disease-free survival were 65.3% and 64.3%, respectively. Nine patients developed grade 3 leukopenia. Grade 5 acute toxicity was not observed in any of the patients; however, 2 patients developed Grade 3 late toxicity. 3D-RT or IMRT is effective for the treatment of recurrent and metastatic cervical cancer, with the 3-year overall survival of 56.1%, and its complications are acceptable. Long-term follow-up and further studies are needed to confirm the role of 3D-RT or IMRT in the multimodality management of the disease.

    After curative local therapy, biochemical recurrence is a mode of relapse among patient with prostate cancer (PC). Deferring androgen deprivation therapy (ADT) or offering non-hormonal therapies may be an appropriate option for these non-symptomatic patients with no proven metastases. Metronomic cyclophosphamide (MC) has shown activity in metastatic PC setting and was chosen to be assessed in biochemical relapse. This prospective single-arm open-label phase II study was conducted to evaluate MC regimen in patients with biochemical recurrent PC. MC was planned to be administered orally at a daily dose of 50 mg for 6 months. Primary endpoint was PSA response. Thirty-eight patients were included and treated. Median follow-up was 45.5 months (range 17-100). Among them, 14 patients (37 %) achieved PSA stabilisation and 22 patients (58 %) experienced PSA progression. Response rate was 5 % with one complete response (2.6 %), and 1 partial response with PSA decrease >50 % (2.6 %). The median time until androgen deprivation therapy initiation was around 15 months. The treatment was well tolerated. Neither grade 3-4 toxicity nor serious adverse events were observed. This first prospective clinical trial with MC therapy in patients with non-metastatic biochemical recurrence of PC displayed modest efficacy when measured with PSA response rate, without significant toxicity. It might offer a new safe and non-expensive option to delay initiation of ADT. These results would need to be confirmed with larger prospective randomised trials. PMID:27400698

    The efficacy of medroxyprogesterone acetate (MPA) therapy in controlling progressive measurable metastatic breast cancer was assessed in 61 patients. In addition serum MPA concentrations were measured by high performance liquid chromatography (HPLC) and subjective effects of treatment were monitored. Overall 24 patients (39.3%) achieved an objective response(2 complete responses [ CR ] and 22 partial responses [ PR ]). There was no significant relationships between response to therapy and menopausal status, metastatic sites, previous therapy, histological type, or disease-free interval. Patients with estrogen (ER) and progesterone (PgR) receptor-positive tumors responded more frequently. Significant differences in serum MPA concentrations were seen between responders and non-responders, objective tumor shrinkage being seen in patients with serum levels in excess of 55 ng/ml. There were few cases responding to the therapy with serum MPA concentrations lower than 25 ng/ml. The serum MPA levels significantly correlated with an improvement in the performance status and survival. Patients with serum MPA concentrations lower than 25 ng/ml had significantly poorer survival. There was a significant relationship between MPA level and dose per area of boby surface (mg/ m(2)) in cases with CR or PR or no change (NC). However, the serum levels of patients with progressive disease despite therapy were lower than the expected levels based on the body surface area. This study demonstrated that serum MPA concentration is a determining factor for therapeutic benefit in advanced or recurrent breast cancer. PMID:11091543

    Cancer patients are frequently affected by malnutrition and weight loss, which affects their prognosis, length of hospital stay, health care costs, quality of life and survival. Our aim was to assess the prognostic value of different scores based on malnutrition or systemic inflammatory response in 91 metastatic or recurrent gastric cancer patients considered for palliative chemotherapy at the Masaryk Memorial Cancer Institute. We investigated their overall survival according to the following measures: Onodera's Prognostic Nutritional Index (OPNI), Glasgow Prognostic Score (GPS), nutritional risk indicator (NRI), Cancer Cachexia Study Group (CCSG), as previously defined, and a simple preadmission weight loss. The OPNI, GPS, and CCSG provided very significant prognostic values for survival (log-rank test P value evaluation of patients' prognosis and should be part of a routine evaluation of patients to provide a timely nutrition support.

    This case highlights the importance of recognition of the pattern of metastatic brachialplexopathy in breast cancer patients undergoing {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) for evaluation of recurrent disease.This pattern can be appreciated on maximum intensity projection (MIP) and coronal {sup 18}F-FDG PET/CT images as a linear extension of tracer activity from superomedial aspect(supra/infraclavicular) to lateral aspect of the axilla closely related to the subclavian/axillary vessels). A 35-year-old woman diagnosed with infiltrating ductal carcinoma of the right breast had undergone six cycles of neoadjuvant chemotherapy, followed by wide local incision and radiotherapy. She had local recurrence, for which she was operated upon and given chemotherapy. She presented to her oncologist with pain and swelling in the right breast, nodules in the right axilla and restriction of movement of the right upper limb. The patient was referred for {sup 18}F-FDG PET/CT to evaluate the extent of recurrent/metastatic disease. Whole-body PET/CT was acquired 1 h following the intravenous injection of 296 MBq of {sup 18}F-FDG on a Biograph mCT scanner (Siemens). Evaluation of the MIP image revealed abnormal FDG accumulation at multiple sites in the thorax, along with a linear pattern of FDG uptake in the right lateral aspect of the upper chest (Fig. 1a, arrow). The coronal fused PET/CT image revealed a linear pattern of FDG uptake corresponding to an ill-defined mass extending from just behind the right clavicle into the right axilla (arrow). In addition, abnormal FDG accumulation was seen in a soft tissue density mass in the upper outer quadrant of the right breast, skin of the right breast laterally, both pectoral muscles (discrete foci) and in a few subpectoral nodes. Soft tissue nodular opacities in both lungs showed FDG accumulation suggestive of pulmonary metastasis (Fig. 1b, thick arrow). The patient was

  6. Capecitabine maintenance therapy in patients with recurrent or metastatic breast cancer

    International Nuclear Information System (INIS)

    Our objective was to investigate the efficacy and safety of capecitabine maintenance therapy (CMT) after capecitabine-based combination chemotherapy in patients with metastatic breast cancer. The clinical data of 139 metastatic breast cancer patients treated from March 2008 to May 2012 with capecitabine-based combination chemotherapy were retrospectively analyzed. When initial disease control was achieved by the combination chemotherapy, we used CMT for 50 patients, while 37 patients were treated with a different (non-CMT) maintenance therapy. We compared time to progression (TTP), objective response rate, disease control rate, clinical benefit rate, and safety of the two groups, and a sub-group analysis was performed according to pathological characteristics. Sixty-four percent of the patients received a median of six cycles of a docetaxel+capecitabine combination chemotherapy regimen (range 1-45); the median TTP (MTTP) for the complete treatment was 9.43 months (95%CI=8.38-10.48 months) for the CMT group and 4.5 months (95%CI=4.22-4.78 months; P=0.004) for the non-CMT group. The MTTPs for the maintenance therapies administered after the initial capecitabine combined chemotherapy were 4.11 months (95%CI=3.34-4.87 months) for the CMT group and 2.0 months (95%CI=1.63-2.38 months) for the non-CMT group. Gastrointestinal side effects, decreased white blood cells and palmar-plantar erythrodysesthesia were the main adverse reactions experienced with the combination chemotherapies, CMT and non-CMT treatments. No significant differences in the incidence of adverse reactions were detected in the CMT and non-CMT patients. After initial disease control was achieved with the capecitabine-based combination chemotherapy, CMT can significantly prolong TTP rates with a favorable safety profile

Methods: A cross-sectional study was carried out in France with patients over 18 years, diagnosed with advanced (stage IIIB–IV or recurrent EOC between 2009 and 2012. A total of 23 physicians (oncologists and gynecologists participated, contributing 127 patients. Data were abstracted by participating physicians into a case report form. Results: Of the 127 patients included, 92 (72.4% had advanced EOC and 35 (27.6% had recurrent EOC. A total of 73 comorbidities were reported in 44 patients (34.6%.

    %) received CRT either prior to or following ASCR. Amenable sites treated with CRT had a better 3-year actuarial local control (80 vs 37%) (p 0.0065) than amenable sites not treated with CRT. Factors associated with improved disease-free survival (DFS) in univariate analysis were induction chemotherapy response (p = 0.002) and extent of surgical resection (p 0.045). There was a trend toward improved DFS on univariate analysis with the use of TBI as part of myeloablative therapy (p = 0.07). The one factor associated with improved OS on univariate analysis was induction chemotherapy response (p = 0.007). Multivariate analysis revealed that induction chemotherapy response is the only factor that remains significant for DFS (p = 0.032) as well as for OS (p = 0.017). Patients with complete response to induction therapy had 40% probability of survival versus all other patients who had 10% survival (p = 0.05). Conclusion: Consolidative radiotherapy is feasible in primary metastatic or recurrent pediatric sarcoma patients treated with myeloablative therapy with or without TBI. CRT to sites amenable to irradiation provided an improved 3-year actuarial local control than that seen in sites amenable to CRT that did not undergo radiotherapy. There was a trend for improved DFS with the use of TBI. Improved DFS and OS can be predicted by response to induction therapy. This intensive regimen may improve the cure rate of advanced pediatric sarcomas in select patients

    BACKGROUND: Patients with radioactive iodine ((131)I)-refractory locally advanced or metastatic differentiated thyroid cancer have a poor prognosis because of the absence of effective treatment options. In this study, we assessed the efficacy and safety of orally administered sorafenib...... in the treatment of patients with this type of cancer. METHODS: In this multicentre, randomised, double-blind, placebo-controlled, phase 3 trial (DECISION), we investigated sorafenib (400 mg orally twice daily) in patients with radioactive iodine-refractory locally advanced or metastatic differentiated thyroid...... cancer. Adverse events were consistent with the known safety profile of sorafenib. These results suggest that sorafenib is a new treatment option for patients with progressive radioactive iodine-refractory differentiated thyroid cancer.

    The surgical outcome of most early gastric cancer (EGC)is usually satisfactory. Some cases show bone metastasis even though the depth of cancer invasion is confined to the mucosa. The most frequent site for recurrence of EGC is the liver. Cases of EGC with bone metastasis are reviewed to clarify the clinicopathological characteristics of EGC giving rise to bone metastasis. Possible mechanisms and risk factors underlying this rare condition are proposed.Forty-six cases of bone metastasis from EGC are reviewed from published reports and meeting proceedings in Japan.This investigation suggests that risk factors for bone metastasis from EGC include depressed-type signet-ring cell carcinoma, poorly differentiated carcinoma, and/or the likely involvement of lymph node metastasis, even though the cancer is confined to the gastric mucosa. The risk factors do not include recurrence of EGC in the liver. We speculate that the mechanism of bone metastasis from EGC is via lymphatic channels and systemic circulation. Postoperative follow-up of cases should consider the development of bone metastasis from EGC. We propose the use of elevated alkaline phosphatase levels for the detection of bone metastasis and recommend bone scintigraphy in positive cases.

    Objective: The aim of our study was to observe the efficacy and adverse reactions of docetaxel plus S1 in patients with advanced metastatic breast cancer. Methods: Twenty-seven patients with advanced metastatic breast cancer receiving docetaxel plus S1 in our hospital were analyzed. The efficacy and safety were evaluated according to RECIST and NCI CTC 3.0. Results: The clinical efficacy and toxicity were evaluated in all the 27 patients, including 1 case of CR, 12 of PR, 6 of SD, and 8 of PD (ORR = 48.1%, CBR = 70.3%). The median time to tumor progression (mTTP) was 7.3 months. No IV degree of adverse reaction was observed in the observation group. Most adverse reactions were degrees I and II, the most common reactions were neutropenia (59.3%), abnormal liver function (33.3%), gastrointestinal adverse events (29.6 %) and stomatitis (7.4%). Conclusion: With good efficacy and low toxicity, docetaxel plus S1 could be administered in the treatment of advanced metastatic breast cancer.

    reported that 60% to 80% of patients with inflammatory breast cancer responded to induction chemotherapy and local control was achieved in approximately 70% of patients by chemotherapy with anthracyclines followed by surgery, postoperative adjuvant chemotherapy, and postoperative radiation therapy. The outcome was improved by induction chemotherapy, and local recurrence within 5 years after mastectomy was observed in 80% to 90% of patients, with local recurrence preceding the occurrence of distant metastasis in 25% to 30%, and is distant metastasis being observed simultaneously in 25%. Local recurrence is treated by radiation therapy, surgery, hyperthermia, and/or chemo-endocrino-therapy. Solitary recurrence can be controlled by resection, while multiple/diffuse recurrence requires radiation therapy. It is unknown whether the combination with chemotherapy improves the prognosis. Intra-arterial administration of antineoplastic agents is used as a method of local control in locally advanced breast cancer. Although intra-arterial administration is known to be superior to systemic administration in terms of primary effect, no differences have been observed in terms of survival rate or response rate. Intra-arterial administration is expected to be effective against distant metastatic lesions. The rate of occurrence of adverse reactions is similar to or less than after systemic administration. Combination therapy consisting of surgery, irradiation, and intra-arterial chemotherapy has been used in the authors' hospital to treat unresectable locally advanced breast cancer and postoperative recurrence of breast cancer. Surgery is performed for locally advanced breast cancer if tumor reduction is observed, and radiation therapy (single anterior 3 MV X-ray dose of 50 Gy / 25 Fr and boost irradiation of 10 Gy) is given depending on the results of the pathological examination. Radiation therapy is given for locally recurrent breast cancer after intra-arterial administration of

    Full Text Available PURPOSE: To assess the cost effectiveness of adding cetuximab to platinum-based chemotherapy in first-line treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC from the perspective of the Canadian public healthcare system. METHODS: We developed a Markov state transition model to project the lifetime clinical and economic consequences of recurrent or metastatic HNSCC. Transition probabilities were derived from a phase III trial of cetuximab in patients with recurrent or metastatic HNSCC. Cost estimates were obtained from London Health Sciences Centre and the Ontario Case Costing Initiative, and expressed in 2011 CAD. A three year time horizon was used. Future costs and health benefits were discounted at 5%. RESULTS: In the base case, cetuximab plus platinum-based chemotherapy compared to platinum-based chemotherapy alone led to an increase of 0.093 QALY and an increase in cost of $36,000 per person, resulting in an incremental cost effectiveness ratio (ICER of $386,000 per QALY gained. The cost effectiveness ratio was most sensitive to the cost per mg of cetuximab and the absolute risk of progression among patients receiving cetuximab. CONCLUSION: The addition of cetuximab to standard platinum-based chemotherapy in first-line treatment of patients with recurrent or metastatic HNSCC has an ICER that exceeds $100,000 per QALY gained. Cetuximab can only be economically attractive in this patient population if the cost of cetuximab is substantially reduced or if future research can identify predictive markers to select patients most likely to benefit from the addition of cetuximab to chemotherapy.

    Objectives: To retrospectively evaluate effectiveness and safety of CT-guided {sup 125}I brachytherapy in 16 patients with mediastinal metastatic lymph nodes recurrence from esophageal carcinoma. Materials and methods: Sixteen metastatic lymph nodes in 16 patients were percutaneously treated in 19 {sup 125}I brachytherapy sessions. Each metastatic lymph node was treated with computed tomographic (CT) guidance. Follow-up contrast material-enhanced CT or positron emission tomographic (PET) scans were reviewed and the treatment's effectiveness was evaluated. Results: Months are counted from the first time of {sup 125}I brachytherapy and the median duration of follow-up was 11 months (range, 5–16 months). The local control rates after 3, 6, 10 and 15 months were 75.0, 50.0, 42.9 and 33.3% respectively. At the time of writing, four patients are alive without evidence of recurrence at 16, 9, 16 and 9 months. The 4 patients presented good control of local tumor and no systemic recurrence, and survived throughout the follow-up period. The other 12 patients died of multiple hematogenous metastases 5–15 months after brachytherapy. A small amount of local hematoma occurred in 2 patients that involved applicator insertion through the lung. Two patients presented pneumothorax with pulmonary compression of 30 and 40% after the procedure and recovered after drainage. One patient had minor displacement of radioactive seeds. Severe complications such as massive bleeding and radiation pneumonitis did not occur. Conclusion: {sup 125}I radioactive seed implantation is effective and may be safely applied to mediastinal metastatic lymph nodes recurrence from esophageal carcinoma.

    Medroxyprogesterone acetate (MPA) is one of the most commonly prescribed drugs for endocrine therapy of metastatic breast cancer. In this study, the serum MPA concentration was measured by high-performance liquid chromatography (HPLC) and evaluated for its usefulness in predicting the response in 79 cases of advanced or recurrent breast cancers. Overall, 29 patients (37%) achieved an objective response. The response rate correlated significantly with the oestrogen receptor (ER) status (P = 0.03), proliferative activity determined by DNA polymerase alpha (P = 0.04), the disease-free interval (DFI) (P = 0.05) and the serum MPA concentration (P < 0.001). Patients with ER-positive tumours, lower proliferative activity, a longer (DFI) or a higher serum MPA concentration responded more frequently. The mean serum MPA concentration in the responders with ER-positive tumours (P = 0.01) or tumours with a lower proliferative activity (P = 0.008) were significantly lower than in cases with ER-negative tumours or tumours with a higher proliferative activity, respectively. Cases with soft tissue metastases showed responses at significantly lower MPA concentrations (P = 0.003) than those with bone or visceral metastases. Furthermore, there was a dramatic decrease in the MPA concentration when a responder with a high concentration became unresponsive to the therapy. Thus, the serum MPA concentration is a determining factor for the response to treatment. PMID:9337682

  19. Tumor phosphatidylinositol-3-kinase signaling and development of metastatic disease in locally advanced rectal cancer.

    Directory of Open Access Journals (Sweden)

    Anne Hansen Ree

    Full Text Available BACKGROUND: Recognizing EGFR as key orchestrator of the metastatic process in colorectal cancer, but also the substantial heterogeneity of responses to anti-EGFR therapy, we examined the pattern of composite tumor kinase activities governed by EGFR-mediated signaling that might be implicated in development of metastatic disease. PATIENTS AND METHODS: Point mutations in KRAS, BRAF, and PIK3CA and ERBB2 amplification were determined in primary tumors from 63 patients with locally advanced rectal cancer scheduled for radical treatment. Using peptide arrays with tyrosine kinase substrates, ex vivo phosphopeptide profiles were generated from the same baseline tumor samples and correlated to metastasis-free survival. RESULTS: Unsupervised clustering analysis of the resulting phosphorylation of 102 array substrates defined two tumor classes, both consisting of cases with and without KRAS/BRAF mutations. The smaller cluster group of patients, with tumors generating high ex vivo phosphorylation of phosphatidylinositol-3-kinase-related substrates, had a particularly aggressive disease course, with almost a half of patients developing metastatic disease within one year of follow-up. CONCLUSION: High phosphatidylinositol-3-kinase-mediated signaling activity of the primary tumor, rather than KRAS/BRAF mutation status, was identified as a hallmark of poor metastasis-free survival in patients with locally advanced rectal cancer undergoing radical treatment of the pelvic cavity.

    2014-01-01

    Full Text Available Stereotactic-irradiation combines highly conformal delivery of radiation to selected volumes at large doses per fraction, with the treatment completed typically within one to five fractions. The radiobiological equivalence of doses delivered by stereotactic-irradiation (often beyond 80–100 Gy is much higher in comparison to the doses achievable by conventional fractionation. At the high fraction sizes used in stereotactic-irradiation, evidence suggests the role of various radiobiological mechanisms of actions, which are not traditionally relatable with conventional radiotherapy. In spite of the accumulating evidence in favour of the efficacy of stereotactic irradiation in terms of improving local control and at times attaining increments in survival, the clinical adoption of the technique remains dismal. This review provides a brief description of the available evidence describing the benefits of stereotactic-irradiation for the management of patients with oligometastases, unresectable malignancies and for disease recurrence after prior radiotherapy. Given the growing body of evidence illustrating the efficacy of stereotactic irradiation among patients with conditions which were previously often regarded as untreatable, it is likely that the widespread adoption of stereotactic irradiation may achieve cure in a few patients, while in the remainder providing prospects of long term local control. This could be a step in the direction of converting incurable malignancies into chronic controllable diseases.

    Breast cancer continues to be one of the most common cancers in North America and Western Europe. Positron emission tomography with 2-[fluorine-18]-fluoro-2-deoxy-D-glucose (FDG PET) represents a non-invasive functional imaging modality that is based on metabolic characteristics of malignant tumours. In breast cancer, FDG PET is more accurate than conventional methods for staging of distant metastases or local recurrences and enables early assessment of treatment response in patients undergoing primary chemotherapy. Recent data indicate a rationale for the use of FDG PET in cases of asymptomatically elevated tumour marker levels in the presence of uncertain results of conventional imaging. Despite the fact that PET cannot rule out microscopic disease, it does have particular value in providing, in a single examination, a reliable assessment of the true extent of the disease. This technique is complementary to morphological imaging for primary diagnosis, staging and re-staging. It may become the method of choice for the assessment of asymptomatic patients with elevated tumour marker levels. This method, however, cannot replace invasive procedures if microscopic disease is of clinical relevance. PMID:15146295

    Bypass surgery for cancer of the pancreatic head is usually done to palliate the obstructive symptoms in the biliary and/or digestive system. However, it is uncommon for patients to require pancreatic duct drainage for recurrent obstructive pancreatitis. In this article, we report a surgical technique of triple bypass consisting of Roux-en-Y hepaticojejunostomy, gastrojejunostomy, and pancreaticojejunostomy for advanced pancreatic cancer. A 76-year-old male patient with locally advanced and metastatic pancreatic head cancer was referred to our department for biliary stricture, duodenal stenosis, and recurrent obstructive pancreatitis associated with persistent pancreatic pseudocyst. In an attempt to resolve all these problems simultaneously, a triple bypass was performed. The patient survived and continued to receive chemotherapy for almost 1 year after surgery without any serious complications. Thus, triple bypass is a useful surgical technique that could relief symptoms and offer better quality of life to patients with advanced pancreatic cancer presenting with biliary stricture, duodenal stenosis, and severe obstructive pancreatitis difficult to treat by medication or endoscopic procedures.

    The prognosis of locally advanced or recurrent squamous cell carcinoma (SCC) of the penis after conventional treatment is dismal. This study aimed to evaluate the therapeutic effects of intraarterial chemotherapy with gemcitabine and cisplatin on local y advanced or recurrent SCC of the penis. Between April 1999 and May 2011, we treated 5 patients with locally advanced penile SCC and 7 patients with recurrent disease with intraarterial chemotherapy. The response rate and toxicity data were analyzed, and survival rates were calculated. After 2 to 6 cycles of intraarterial chemotherapy with gemcitabine and cisplatin, 1 patients with locoregional y advanced disease achieved a complete response, and 4 achieved partial response. Of the 7 patients with recurrent disease, 2 achieved complete response, 3 achieved partial response, 3 had stable disease, and 1 developed progressive disease. An objective tumor response was therefore achieved in 10 of the 12 patients. The median overal survival for the patients was 24 months (range, 10-50 months). Three out of 10 patients who responded were long-term survivors after intraarterial chemotherapy. Intraarterial chemotherapy with gemcitabine and cisplatin may be effective and potential y curative in locoregional y advanced or recurrent penile SCC. The contribution of this therapy in the primary management of advanced or recurrent penile SCC should be prospectively investigated.

    Full Text Available Background: Spinal metastases of patients with advanced stage lung cancer are an important target for palliative therapy, because their incidence is high, and they often cause severe symptoms and worsen the quality of life. Surgery is one of the most effective treatment options, but the indication of surgery is unclear as the procedure is invasive and patients with spinal metastasis have a rather short life expectancy. Furthermore, there have been few studies that have focused on lung cancer with poor prognosis. Methods: We reviewed all of the cases of lung cancer from January 1999 to July 2007 in the Department of Respiratory Medicine, Kyoto University Hospital, Japan. Thirteen patients with metastatic spinal tumor of lung cancer underwent surgery, and all of them had a poor performance status score (3 or 4. Results: Neurological improvement by at least 1 Frankel grade was seen in 10 of 14 cases (71%. Improvement of the movement capacity was noted in 9 of 14 cases (64%, and pain improvement was noted in 12 of 14 (86%. Median postoperative survival was 5 months (1–25 months. In particular, the group with a good postoperative performance status score (0–2 was shown to have a better median postoperative survival of 13 months. Conclusions: Surgical treatment for symptomatic metastatic spinal tumor of lung cancer can improve quality of life in a substantially high percentage of patients. Surgery should be considered even if preoperative performance status is poor.

    Purpose: To investigate the clinical value of 18F-FDG SPECT with coincidence in the diagnosis of recurrent or metastatic tumor of digestive system. Methods: 35 cases of postoperative patients with tumor of digestive system were enrolled in this study with 18F-FDG SPECT with coincidence. The results were analyzed by calculating its accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and 95% confidence interval and compared with UB, CT and MRI. Results: In 35 cases of postoperative patients with tumor of digestive system, the accuracy, sensitivity, specificity, PPV and NPV were 91.4%, 88.9%, 100%, 100%, 72.7%, respectively, and their 95% confidence interval were 77% - 98%, 71% - 98%, 63% - 100%, 86% - 100%, 39% - 94%, respectively. The diagnostic accuracy and sensitivity of 18F-FDG SPECT with coincidence were significantly higher than that of UB, while there were no significant difference between the result of other 18F-FDG SPECT with coincidence and CT and MRI. The analysis of 95% confidence interval showed a higher tendency in 18F-FDG SPECT with coincidence than in UB, CT and MRI. There is complementation among 18F-FDG SPECT with coincidence combined with UB, CT and MRI in some cases. Conclusions: 18F-FDG SPECT/PET has high clinical value in the diagnosis of recurrent or metastatic tumor of digestive system. (authors)

    Full Text Available Abstract Introduction Chondrosarcomas and chordomas are usually chemoresistant bone tumors and may have a poor prognosis when advanced. They are usually associated with worsening pain difficult to control. Patients and Methods Zoledronic acid was used in a 63-year-old man with metastatic chondrosarcoma and in a 66-year-old woman with a diagnosis of sacrum chordoma both reporting severe pain related to tumor. Results In the first case, zoledronic acid was able to maintain pain control despite disease progression following chemotherapy, in the other case, zoledronic acid only produced significant clinical benefit. Conclusion Control of pain associated with bone tumors such as chondrosarcoma and chondroma may significantly improve from use of zoledronic acid, independently from tumor response to other treatments. Evaluation on larger series are needed to confirm the clinical effect of this bisphosphonate on such tumors.

    We evaluated the diagnostic performance of FDG-PET for the detection of metastatic cervical lymph nodes in recurrent papillary thyroid carcinoma patients with negative I-131 scan. All patients had total thyroidectomy and following I-131 ablation therapy. In the follow-up period, FDG-PET showed suspected cervical lymph nodes metastases and neck dissection was performed within 3 months after FDG-PET. It had shown for all patients the negative I-131 scan within 3 months before FDG-PET or negative I-131 scan during the period of cervical lymph nodes metastases suspected on the basis of FDG-PET, CT, or ultrasonography until the latest FDG-PET. Preoperative FDG-PET results were compared with the pathologic findings of lymph nodes specimens of 19 papillary thyroid carcinoma patients. Serum Tg, TSH, and Tg antibody levels at the time of latest I-131 scan were reviewed. The size of lymph node was measured by preoperative CT or ultrasonography. In 45 cervical lymph node groups dissected, 31 lymph node groups revealed metastasis. The sensitivity and specificity of FDG-PET for metastasis were 74.2% (23 of 31) and 50.0% (7 of 14), respectively. Except for patients with elevated Tg antibody levels, all patients showed the elevated serum Tg levels than normal limits at the TSH of =30uIU/ml. 8 lesions without suspected metastatic findings on FDG-PET revealed metastasis (false negative), and none of them exceeded 8mm in size (4 to 8mm, median= 6mm). On the other hand, 23 true positive lesions on FDG-PET were variable in size (6 to 17mm, median=9mm). FDG-PET is suitable for the detection of metastatic cervical lymph nodes in patients with recurrent papillary thyroid carcinoma. However, false positive or false negative should be considered according to the size of lymph node.

    Metastatic gastric cancer remains an incurable disease,with a relative 5-year survival rate of 7%-27%.Chemotherapy,which improves overall survival (OS) and quality of life,is the main treatment option.Metaanalysis has demonstrated that the best survival results obtained in earlier randomized studies were achieved with three-drug regimens containing a fluoropyrimidine,an anthracycline,and cisplatin (ECF).Although there has been little progress in improving median OS times beyond the 9-mo plateau achievable with the standard regimens,the availability of newer agents has provided some measure of optimism.A number of new combinations incorporating docetaxel,oxaliplatin,capecitabine,and S-1 have been explored in randomized trials.Some combinations,such as epirubicin-oxaliplatincapecitabine,have been shown to be as effective as (or perhaps more effective than) ECF,and promising early data have been derived for S-1 in combination with cisplatin.One factor that might contribute to extending median OS is the advancement whenever possible to second-line cytotoxic treatments.However,the biggest hope for significant survival advances in the near future would be the combination of new targeted biological agents with existing chemotherapy first-line regimens.

  17. On the development of models in mice of advanced visceral metastatic disease for anti-cancer drug testing.

    2007-12-01

    It is well known clinically that advanced, bulky visceral metastatic disease is generally much less responsive to most anti-cancer therapies, compared to microscopic metastatic disease. This problem is exacerbated when treating cancers that have been previously exposed to multiple lines of therapy, and which have acquired a 'refractory' phenotype. However, mimicking such clinical treatment situations in preclinical mouse models involving the testing of new or existing cancer therapies is extremely rare. Treatment of 'metastasis', in retrospect, usually involves minimal residual disease and therapy naïve tumors. This could account in many instances for the failure to reproduce highly encouraging preclinical results in subsequent phase I or phase II clinical trials. To that end, we have embarked on an experimental program designed to develop models of advanced, visceral metastatic disease, in some cases involving tumors previously exposed to various therapies. The strategy first involves the orthotopic transplantation of a human cancer cell line, such as breast cancer cell line, into the mammary fat pads of immune deficient mice, followed by surgical resection of the resultant primary tumors that develops. Recovery of distant macroscopic metastases, usually in the lungs, is then undertaken, which can take up to 4 months to visibly form. Cell lines are established from such metastases and the process of orthotopic transplantation, surgical resection, and recovery of distant metastases is undertaken, at least one more time. Using such an approach highly metastatically aggressive variant sublines can be obtained, provided they are once again injected into an orthotopic site and the primary tumors removed by surgery. By waiting sufficient time after removal of the primary tumors, about only 1 month, mice with extensive metastatic disease in sites such as the lungs, liver, and lymph nodes can be obtained. An example of therapy being initiated in an advanced stage of such

    International Nuclear Information System (INIS)

    We have investigated the usefulness of combination therapy with radiation and CHFU for advanced and recurrent breast cancer according to a clinical cotrolled multicenter trial from 1982 to 1984. One hundred cases were registered and 82 of them were availabe. Treatment sites were the lymph nodes, skin, bone and lung, and the overall response rate was 58% in CR and 19% in PR, while the duration of remission was 18 weeks in CR. Side effects were found in 10% of the patients. Combination therapy with radiation and HCFU may be useful in multimodal tretment for advanced recurrent breast cancer. (author)

    Full Text Available Yanni Hao,1 Verena Wolfram,2 Jennifer Cook2 1Novartis Pharmaceuticals, East Hanover, NJ, USA; 2Adelphi Values, Bollington, UK Background: Health utilities are increasingly incorporated in health economic evaluations. Different elicitation methods, direct and indirect, have been established in the past. This study examined the evidence on health utility elicitation previously reported in advanced/metastatic breast cancer and aimed to link these results to requirements of reimbursement bodies. Methods: Searches were conducted using a detailed search strategy across several electronic databases (MEDLINE, EMBASE, Cochrane Library, and EconLit databases, online sources (Cost-effectiveness Analysis Registry and the Health Economics Research Center, and web sites of health technology assessment (HTA bodies. Publications were selected based on the search strategy and the overall study objectives. Results: A total of 768 publications were identified in the searches, and 26 publications, comprising 18 journal articles and eight submissions to HTA bodies, were included in the evidence review. Most journal articles derived utilities from the European Quality of Life Five-Dimensions questionnaire (EQ-5D. Other utility measures, such as the direct methods standard gamble (SG, time trade-off (TTO, and visual analog scale (VAS, were less frequently used. Several studies described mapping algorithms to generate utilities from disease-specific health-related quality of life (HRQOL instruments such as European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 30 (EORTC QLQ-C30, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Breast Cancer 23 (EORTC QLQ-BR23, Functional Assessment of Cancer Therapy – General questionnaire (FACT-G, and Utility-Based Questionnaire-Cancer (UBQ-C; most used EQ-5D as the reference.

    This study presents immunoscintigraphic results in 24 patients suffering from primary colorectal cancer, recurrent or metastatic disease after the injection of 1197-1351 MBq technetium-99m labelled totally human monoclonal antibody 88BV59. Labelling efficacy of 99mTc-88BV59 ranged from 97% to 99%. Immunoscintigraphy was performed 18-20 h after injection. Scintigraphic findings were compared with those of computed tomography (CT). Patients underwent surgery in order to evaluate immunoscintigraphic findings histologically. Sera of the patients (before injection and 1 and 3 months post infusion) were analysed for the presence of human anti-human antibodies (HAHA). None of the patients showed a HAHA response as assessed by a solid-phase ELISA assay. The antibody scan detected about 25% more lesions than CT. In the detection of extrahepatic disease, the sensitivity of the antibody scan proved to be 68%, whereas the sensitivity of CT was 41%. (orig.). With 3 figs., 1 tab

    Full Text Available Over the past 30 years, there has been no significant improvement in treatment outcomes for patients with advanced stage IV metastatic melanoma, and prognosis remains poor. Melanoma is known to be responsive to immunomodulatory agents, to be a highly vascular tumor, and to be fairly resistant to standard cytotoxic chemotherapy. Ongoing research is attempting to find novel combinations that may have therapeutic synergy. Alternative dosedense schedules of temozolomide appear promising and are being actively investigated, based on their potential to overcome chemoresistance to alkylating agents and the proven activity of temozolomide in the brain. Outcomes of studies investigating single-agent temozolomide suggest that it has activity similar to single-agent dacarbazine. Other studies combining temozolomide with either interferon- alfa or thalidomide suggest that the addition of these immunomodulatory agents to temozolomide improves response rates and may improve overall survival. The best results have been achieved with the extended, daily, dosedense temozolomide regimen. Further research is needed to determine the optimal temozolomide regimen and best combination approach

    Adrenocortical carcinoma (ACC) is an aggressive malignancy, which lacks an effective systemic treatment. Abnormal activation of insulin-like growth factor receptor 1 (IGF1R) has been frequently observed. Preclinical studies demonstrated that pharmacological inhibition of IGF1R signaling in ACC has antiproliferative effects. A previous phase I trial with an IGF1R inhibitor has demonstrated biological activity against ACC. The objective of this study is to assess the efficacy of the combination of the IGF1R inhibitor cixutumumab (IMC-A12) in association with mitotane as a first-line treatment for advanced/metastatic ACC. We conducted a multicenter, randomized double-arm phase II trial in patients with irresectable recurrent/metastatic ACC. The original protocol included two treatment groups: IMC-A12 + mitotane and mitotane as a single agent, after an initial single-arm phase for safety evaluation with IMC-A12 + mitotane. IMC-A12 was dosed at 10 mg/kg intravenously every 2 weeks. The starting dose for mitotane was 2 g daily, subsequently adjusted according to serum levels/symptoms. The primary endpoint was progression-free survival (PFS) according to RECIST (Response Evaluation Criteria in Solid Tumors). This study was terminated before the randomization phase due to slow accrual and limited efficacy. Twenty patients (13 males, 7 females) with a median age of 50.2 years (range 21.9-79.6) were enrolled for the single-arm phase. Therapeutic effects were observed in 8/20 patients, including one partial response and seven stable diseases. The median PFS was 6 weeks (range 2.66-48). Toxic events included two grade 4 (hyperglycemia and hyponatremia) and one grade 5 (multiorgan failure). Although the regimen demonstrated activity in some patients, the relatively low therapeutic efficacy precluded further studies with this combination of drugs. PMID:24849545

    Full Text Available Abstract Background The high frequency of local recurrence occurring after endoscopic piecemeal resection (EPMR for large colorectal tumors is a serious problem. However, almost all of these cases of local recurrence can be detected within 1 year and cured by additional endoscopic resection. We report a rare case of recurrent advanced colonic cancer diagnosed 11 years after initial EPMR treatment. Case presentation A 65-year-old male was diagnosed with a sigmoid colon lesion following a routine health check-up. Total colonoscopy revealed a 12 mm type 0-Is lesion in the sigmoid colon, which was diagnosed as an adenoma or intramucosal cancer and treated by EPMR in 1996. The post-resection defect was closed completely using metallic endoclips to avoid delayed bleeding. In 2007, at the third follow up, colonoscopy revealed a 20 mm submucosal tumor (SMT like recurrence at the site of the previous EPMR. The recurrent lesion was treated by laparoscopic assisted sigmoidectomy with lymph node dissection. Conclusion When it is difficult to evaluate the depth and margins of resected tumors following EPMR, it is important that the defect is not closed in order to avoid tumor implantation, missing residual lesions and to enable earlier detection of recurrence. It is crucial that the optimal follow-up protocol for EPMR cases is clarified, particularly how often and for how long they should be followed.

    Full Text Available Currently the diagnosis of local recurrence of prostate cancer (PCa after radical prostatectomy (RT is based on the onset of biochemical failure which is defined by two consecutive values of prostate-specific antigen (PSA higher than 0.2 ng/mL. The aim of this paper was to review the current roles of advanced imaging in the detection of locoregional recurrence. A nonsystematic literature search using the Medline and Cochrane Library databases was performed up to November 2013. Bibliographies of retrieved and review articles were also examined. Only those articles reporting complete data with clinical relevance for the present review were selected. This review article is divided into two major parts: the first one considers the role of PET/CT in the restaging of PCa after RP; the second part is intended to provide the impact of multiparametric-MRI (mp-MRI in the depiction of locoregional recurrence. Published data indicate an emerging role for mp-MRI in the depiction of locoregional recurrence, while the performance of PET/CT still remains unclear. Moreover Mp-MRI, thanks to functional techniques, allows to distinguish between residual glandular healthy tissue, scar/fibrotic tissue, granulation tissue, and tumour recurrence and it may also be able to assess the aggressiveness of nodule recurrence.

    Metronomic antiangiogenic chemotherapy, the prolonged administration of relatively low drug doses, at close regular intervals with no significant breaks, has been mainly studied at the preclinical level using single chemotherapeutic drugs, frequently in combination with a targeted antiangiogenic drug, and almost always evaluated on primary localized tumors. We tested a "doublet" combination metronomic chemotherapy treatment using two oral drugs, UFT, a 5-fluorouracil (5-FU) prodrug administered by gavage, and cyclophosphamide, for efficacy and toxicity in a new mouse model of advanced, terminal, metastatic human breast cancer. The optimal biological dose of each drug was first determined by effects on levels of circulating endothelial progenitor cells as a surrogate marker for angiogenesis, which was assessed to be 15 mg/kg for UFT and 20 mg/kg for cyclophosphamide. A combination treatment was then evaluated in mice with advanced metastatic disease using a serially selected metastatic variant of the MDA-MB-231 breast cancer-cell line, 231/LM2-4. UFT or cyclophosphamide treatment showed only very modest survival advantages whereas a combination of the two resulted in a remarkable prolongation of survival, with no evidence of overt toxicity despite 140 days of continuous therapy, such that a significant proportion of mice survived for over a year. In contrast, this striking therapeutic effect of the combination treatment was not observed when tested on primary orthotopic tumors. We conclude that combination oral low-dose daily metronomic chemotherapy, using cyclophosphamide and UFT, is superior to monotherapy and seems to be a safe and highly effective experimental antimetastatic therapy, in this case, for advanced metastatic breast cancer.

  7. MDCT of primary, locally recurrent, and metastatic duodenal gastrointestinal stromal tumours (GISTs): A single institution study of 25 patients with review of literature

    International Nuclear Information System (INIS)

    Aim: To describe the multidetector computed tomography (MDCT) features of primary, locally recurrent, and metastatic duodenal gastrointestinal stromal tumours (GISTs). Materials and methods: In this institutional review board-approved, Health Insurance Portability and Accountability Act of 1996 (HIPAA)-compliant, retrospective study, 25 patients [13 men, 12 women; mean age 56 years (34–74 years)] with histopathologically confirmed duodenal GISTs seen at Dana Farber Cancer Institute and Brigham and Women's Hospital from December 1999 to October 2009 were identified. The MDCT of primary tumours in six patients and follow-up imaging in all the 25 patients was reviewed by two radiologists in consensus. Electronic medical records were reviewed to document the clinical characteristics and management. Results: The mean size of the primary tumour was 3.7 cm (range 2.5–5.6 cm). Three of six primary tumours were in the second and third portions of the duodenum, one in the third portion, one in the third and fourth portions, and one in the fourth portion. Three of six of the tumours were exophytic, two were both exophytic and intraluminal, and one was intramural. The tumours were well-circumscribed, round or oval masses, with few lobulations, and were either homogeneously hyper-enhancing or heterogeneously isodense at MDCT. None of the tumours had necrosis, haemorrhage, calcification, or loco regional lymphadenopathy on imaging. Sixteen of 25 (64%) patients developed metastatic disease, the most common sites being liver (14/16; 87.5%) and peritoneum (5/16; 31%). Conclusion: Duodenal GISTs are well-circumscribed, round or oval masses, and occur in the second through fourth portions of the duodenum, without lymphadenopathy or duodenal obstruction. Duodenal GISTS metastasize frequently to the liver and peritoneum

    Background: uterine sarcomas are rare tumors. Until now, no data on the treatment of recurrent or advanced uterine sarcomas using concurrent radiochemotherapy (RCT) has been available. Patients and methods: from 01/1997 to 03/2004, seven patients with locally recurrent (n = 6) or locally advanced uterine sarcomas (n = 1) received concurrent RCT after tumor surgery (R1/2 resection in 3/7 patients). A total radiation dose of 45 Gy was applied in single doses of 1.8 Gy using an external-beam technique; in addition, three to four intracavitary doses of 5 Gy were applied. Concurrent chemotherapy was generally administered as follows: 1.2 g/m{sup 2} ifosfamide on days 1-5 and 29-33 in combination with 50 or 40 mg/m{sup 2} adriamycin on days 2 and 30. 3/7 patients received further cycles of chemotherapy. The median follow-up was 35 months. Results: all recurrences (before RCT) were localized either in the vagina or in or directly proximal to the vaginal stump. The main side effects of RCT were hemotoxicity (grade 3: n = 3/7; grade 4: n = 4/7; neutropenic fever n = 1/7) and diarrhea (grade 3: n = 5/7). At the median follow-up (35 months), 4/7 patients had recurrences (one local recurrence; one lymph node recurrence outside the irradiated field, two distant metastases). Local control in the irradiated field was 80% {+-} 18% after 3 years. Disease-free survival calculated according to Kaplan-Meier was 57% {+-} 19% after 3 years. Presently, 5/7 patients are still alive, corresponding to a 3-year survival rate of 83% {+-} 15%. Conclusion: concurrent RCT shows good local effectiveness with a good long-term survival. Further evaluation in phase II studies is recommended. (orig.)

    In the treatment of recurrent breast cancer in patients previously treated with anthracycline drugs, taxane drugs are generally used. This time, we retrospectively studied the safety of docetaxel/cyclophosphamide combination therapy (hereinafter referred to as TC therapy). Ten patients (mean age: 52.8 years old) were included in the study. Metastatic/recurrent sites included 3 skin, 2 each of contralateral breast, lung and bone, and 1 each of liver, carcinomatous pleurisy and supraclavicular lymph node. Seven patients had a history of anthracycline treatment. The patients received TC at doses of 60 mg/m(2) and 500 mg/m(2), respectively, every 3 weeks. With regard to adverse events, non-hematotoxic events included alopecia in all the patients, generalized malaise in 5, and abnormal nail in 1. Hematotoxic events were grades 2 and 3 decreased neutrophil count in 5 patients. One patient had grade 4 pyrexia associated with oral candida. The patient was admitted and treated with fluid replacement and granulocyte colony-stimulating factor (G-CSF). There were no other patients in whom the treatment was prolonged or dosage was reduced due to adverse reactions. TC therapy is considered to be a beneficial treatment method in terms of safety since it can be instituted on an outpatient basis. PMID:17033252

    AIM: To investigate the prognostic impact of the metastatic lymph node ratio (MLR) in advanced gastric cancer from the cardia and fundus. METHODS: Two hundred and thirty-six patients with gastric cancer from the cardia and fundus who underwent D2 curative resection were analyzed ret- rospectively. The correlations between MLR and the total lymph nodes, positive nodes and the total lymph nodes were analyzed respectively. The influence of MLR on the survival time of patients was determined with univariate Kaplan-Meier survival analysis and mul- tivariate Cox proportional hazard model analysis. And the multiple linear regression was used to identify the relation between MLR and the 5-year survival rate of the patients. RESULTS: The MLR did not correlate with the total lymph nodes resected (r = -0.093, P = 0.057). The 5-year overall survival rate of the whole cohort was 37.5%. Kaplan-Meier survival analysis identified that the following eight factors influenced the survival time of the patients postoperatively: gender (X2 = 4.26, P = 0.0389), tumor size (X2 = 18.48, P < 0.001), Borrmann type (X2 = 7.41, P = 0.0065), histological grade (X2 =5.07, P = 0.0243), pT category (X2 = 49.42, P < 0.001), pN category (X2 = 87.7, P < 0.001), total number of re- trieved lymph nodes (X2 = 8.22, P = 0.0042) and MLR (X2 = 34.3, P < 0.001). Cox proportional hazard model showed that tumor size (X2 = 7.985, P = 0.018), pT category (X2 = 30.82, P < 0.001) and MLR (X2 = 69.39, P < 0.001) independently influenced the prognosis. A linear correlation between MLR and the 5-year survival was statistically significant based on the multiple lin- ear regression (β = -0.63, P < 0.001). Hypothetically, the 5-year survival would surpass 50% when MLR was lower than 10%. CONCLUSION: The MLR is an independent prognostic factor for patients with advanced gastric cancer from the cardia and fundus. The decrease of MLR due to adequate number of total resected lymph nodes can improve the survival.

    The aim of this study was to evaluate the efficacy and safety of co-administration of oral S-1 and oxaliplatin (SOX) in combination with bevacizumab (bev) in patients with advanced recurrent colorectal cancer. A retrospective study of 36 patients with advanced recurrent colorectal cancer was performed, of whom 27 received first-line and 9 received second-line SOX+bev chemotherapy between 2010 and 2013 at the Hachioji Digestive Disease Hospital (Hachioji, Japan). The SOX+bev regimen consisted of administration of intravenous oxaliplatin (85 mg/m2) on days 1 and 14, bevacizumab (5 mg/kg) on day 1, and co-administration of oral S-1 twice daily on days 1–14. The drug regimen was repeated every 4 weeks. SOX+bev treatment was associated with a response rate of 45.2%, a disease control rate of 71%, and a median progression-free survival (PFS) and overall survival (OS) of 9.9 and 21.9 months, respectively. Patients who received first-line chemotherapy benefited from treatment in terms of prolonged PFS (13.8 months) and OS (28.2 months). Grade 3/4 adverse events were infrequent and included anaemia, thrombocytopenia, anorexia, diarrhea, sensory neuropathy, increased aspartate aminotransferase level and skin rash. In conclusion, SOX+bev therapy was found to be feasible and safe for patients with advanced and recurrent colorectal cancer.

    Background Health utilities are increasingly incorporated in health economic evaluations. Different elicitation methods, direct and indirect, have been established in the past. This study examined the evidence on health utility elicitation previously reported in advanced/metastatic breast cancer and aimed to link these results to requirements of reimbursement bodies. Methods Searches were conducted using a detailed search strategy across several electronic databases (MEDLINE, EMBASE, Cochrane Library, and EconLit databases), online sources (Cost-effectiveness Analysis Registry and the Health Economics Research Center), and web sites of health technology assessment (HTA) bodies. Publications were selected based on the search strategy and the overall study objectives. Results A total of 768 publications were identified in the searches, and 26 publications, comprising 18 journal articles and eight submissions to HTA bodies, were included in the evidence review. Most journal articles derived utilities from the European Quality of Life Five-Dimensions questionnaire (EQ-5D). Other utility measures, such as the direct methods standard gamble (SG), time trade-off (TTO), and visual analog scale (VAS), were less frequently used. Several studies described mapping algorithms to generate utilities from disease-specific health-related quality of life (HRQOL) instruments such as European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Core 30 (EORTC QLQ-C30), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – Breast Cancer 23 (EORTC QLQ-BR23), Functional Assessment of Cancer Therapy – General questionnaire (FACT-G), and Utility-Based Questionnaire-Cancer (UBQ-C); most used EQ-5D as the reference. Sociodemographic factors that affect health utilities, such as age, sex, income, and education, as well as disease progression, choice of utility elicitation method, and country settings, were identified

    For patients with recurrent/metastatic (R/M) head and neck squamous cell carcinoma (SCCHN) limited therapeutic options exist. Only a subset of patients is suitable for combination chemotherapy regimens. Biweekly docetaxel plus cetuximab might be an alternative option. Thus, we performed this retrospective analysis in unselected patients in order to investigate the efficacy and safety of this regimen. Thirty-one patients receiving off protocol docetaxel (50 mg/m2) plus cetuximab (500 mg/m2) biweekly were included. Data collection included baseline demographic, response rate (ORR), disease control rate (DCR), overall survival (OS), progression free survival (PFS) as well as toxicity. OS and PFS were 8.3 months (95% CI 4.8–11.8) and 4.0 months (95% CI 1.0–7.0), respectively. Three (9.7%) patients achieved a complete response and one patient (3.2%) a partial response. The DCR was 41.9% and we observed an ORR of 12.9%. The one-year survival rate was 25.8%. The therapy was well tolerated and the most common grade 3/4 adverse events were neutropenia (19.4%), hypomagnesaemia (12.9%) and acne-like rash (9.7%). Biweekly cetuximab/docetaxel is an effective regimen and well tolerated in R/M SCCHN patients not suitable for platinum doublet treatment. Further evaluation of this regimen in prospective clinical trials is warranted.

    2012-01-01

    Full Text Available Successful management of breast cancer in the metastatic setting is often confounded by resistance to chemotherapeutics, in particular anthracyclines and taxanes. The limited number of effective treatment options for patients with more aggressive biological subtypes, such as triple-negative metastatic breast cancer, is especially concerning. As such, a therapy clinically proven to be effective in this subtype would be of great value. Ixabepilone, a novel synthetic lactam analog of epothilone B, demonstrated better clinical outcomes in metastatic disease, particularly in triple-negative breast cancer. Most recently, studies have shown the activity of ixabepilone in the neoadjuvant setting, suggesting a role for this drug in primary disease. Notably, treating in the neoadjuvant setting might allow clinicians to explore the predictive value of biomarkers and response to treatment, as pharmacogenomic approaches to therapy continue to evolve. In this article, we review the efficacy and safety data of ixabepilone as a monotherapy and as a component of combination therapy for metastatic and primary breast cancer.

    Objectives Recurrence rates for patients with locally advanced renal cell carcinoma (LARCC) remain high. To date the predictors of recurrence in those patients remain controversial. The aim of the present study was to assess the relapse pattern in those patients and identify predictors for recurrence. Patients and methods We evaluated retrospectively 112 consecutive patients who underwent surgery for LARCC (T3–T4N0M0) between January 2000 and December 2010. Clinical and pathological data were collected from hospital medical records and compiled into a computerized database. Studied variables were age, mode of presentation, Tumour-Node-Metastasis (TNM) stage, Fuhrman nuclear grade, histological subtype, tumour size, venous thrombus level, collecting-system invasion and sarcomatoid differentiation. Recurrence-free survival (RFS) was estimated using the Kaplan–Meier method. Univariate and multivariate analyses were conducted. Results Patients were followed for a mean and median follow-up of 33 and 24 months, respectively, after surgery. During the follow-up, recurrences (distant and/or local) were recorded in 58 patients, representing 52% of the cohort. The mean and median times to recurrence were 25 and 13 months, respectively. Sites of recurrence were multiple in 36 patients (62%), lung only in 14 (24%), and local in eight (14%). RFS rates at 1, 2, and 5 years were 50%, 43% and 34%, respectively, while the median RFS was 23.7 months. Using univariate analysis, RFS after nephrectomy was significantly shorter in patients aged <70 years, symptomatic at presentation, with larger tumours, higher nuclear grade, collecting-system invasion, and/or sarcomatoid differentiation. After multivariate analysis, T-stage, nuclear grade and sarcomatoid differentiation retained their power as independent predictors of RFS (P = 0.032, <0.001 and 0.003, respectively). Conclusions For patients with LARCC, T-stage, grade and sarcomatoid differentiation independently dictate the

    Eighteen patients with 25 unresectable advanced or recurrent head and neck cancers (squamous cell carcinomas) received thermochemotherapy in combination with radiotherapy. The total radiation dose ranged from 50 to 82 Gy (mean, 65.6 Gy). Patients received thermochemotherapy twice a week, for a total number of 8.8 sessions, on average. The temperature in the tumor, as a result of the hyperthermia, was over 42 deg C in 185 (84.5%) of the 219 treatments. Three kinds of heating systems were used: a 13.56-MHz radiofrequency system, a 2450-MHz microwave system, and a radiofrequency interstitial system. The total amount of administered CDDP ranged from 40 to 300 mg (mean, 110 mg), combined with PEP and/or 5FU. Background factors (tumor factors and treatment factors) were investigated in detail, and the clinical results (tumor response and the 5-year cumulative focal control rate) were evaluated. The relationship between these two results was then analyzed using univariate and multivariate statistics. The clinical results of patients with a WHO histological classification of grade 3 were poor compared with patients with a classification of grade 1 or 2. The difference between these two results was significant when analyzed using univariate statistics, but not significant when analyzed using multivariate statistics. The clinical results of patients with primary lesions surrounded by bony tissues were slightly poor compared with those of patients whose lesions were surrounded by soft tissues, but the difference between these two results was not significant. Successful treatment of refractory recurrent tumors, large tumor masses, and diffuse invasive carcinomas was not affected by the treatment factors (heating systems, heating sessions, radiation dose, and CDDP dose and drug combination). These results suggest that refractory recurrence, proximity to bony tissues, tumor size, and histological malignancy might not be prognostic variables for thermochemoradiotherapy strategy

    The emergence of immune checkpoint inhibitors marked an important advancement in the development of cancer therapeutics. Pembrolizumab is a selective humanized IgG4 kappa monoclonal antibody that inhibits the programmed death-1 (PD-1) receptor, an integral component of immune checkpoint regulation in the tumor microenvironment. The drug is currently approved by the Food and Drug Administration for the treatment of advanced melanoma and metastatic squamous and nonsquamous non-small cell lung cancer (NSCLC). Several published studies demonstrate that single-agent pembrolizumab is safe and has efficacy in patients with NSCLC. Many ongoing protocols are investigating the role of pembrolizumab in combination with other agents in lung cancer and various other cancer types. We review the available data on pembrolizumab in NSCLC and examine the role of potential predictive biomarkers of response to therapy.

    AIM: To develop and validate a risk score for advanced colorectal adenoma (ACA) recurrence after endoscopic polypectomy. METHODS: Out of 3360 patients who underwent colon polypectomy at University of Foggia between 2004 and 2008, data of 843 patients with 1155 ACAs was retrospectively reviewed. Surveillance intervals were scheduled by guidelines at 3 years and primary endpoint was considered 3-year ACA recurrence. Baseline clinical parameters and the main features of ACAs were entered into a Cox regression analysis and variables with P < 0.05 in the univariate analysis were then tested as candidate variables into a stepwise Cox regression model (conditional backward selection). The regression coefficients of the Cox regression model were multiplied by 2 and rounded in order to obtain easy to use point numbers facilitating the calculation of the score. To avoid overoptimistic results due to model fitting and evaluation in the same dataset, we performed an internal 10-fold cross-validation by means of bootstrap sampling. RESULTS: Median lesion size was 16 mm (12-23) while median number of adenomas was 2.5 (1-3), whereof the number of ACAs was 1.5 (1-2). At 3 years after polypectomy, recurrence was observed in 229 ACAs (19.8%), of which 157 (13.5%) were metachronous neoplasms and 72 (6.2%) local recurrences. Multivariate analysis, after exclusion of the variable “type of resection” due to its collinearity with other predictive factors, confirmed lesion size, number of ACAs and grade of dysplasia as significantly associated to the primary outcome. The score was then built by multiplying the regression coefficients times 2 and the cut-off point 5 was selected by means of a Receiver Operating Characteristic curve analysis. In particular, 248 patients with 365 ACAs fell in the higher-risk group (score ≥ 5) where 3-year recurrence was detected in 174 ACAs (47.6%) whereas the remaining 595 patients with 690 ACAs were included in the low-risk group (score < 5) where 3

    At present there is no oral medicine available which is effective for advanced or recurrent case of elderly patients with gynecologic cancer. We report that a low-dose biweekly paclitaxel administration preserves quality of life (QOL) and seems to be "tumor dormancy like" therapy of good compliance with few side effects. A total of 11 cases were in ovarian cancer (5), uterine cancer (3), cervical cancer (2), and uterine sarcoma (1). The median age was 68 years old and the age range was 50 to 79 years old. We performed a standard treatment as a first time treatment. Afterwards, we obtained complete informed consent from the patients for progressive or recurrent cancer and administered biweekly paclitaxel 70 mg/m2 (80-100 mg/body) on an outpatient basis. We reviewed the effect, side effect and compliance of the medication. We judged the side effect based on the Japanese cancer treatment society common toxicity criteria. The result was only one patient death from PD and the other 10 patients were PR or a state of NC without side effect. An ovary cancer case patient lived for 67 months at best, an endometrial cancer case patient lived for 62 months at best, a cervical cancer case patient lived for 74 months at best, and a recurrent uterine sarcoma case patient lived for 76 months after recurrence and the QOL was good. In addition, there was no onset of side effect more than grade 2 in all of the cases and a compliance of medical administration was good. In these cases, we thought that a low-dose of biweekly paclitaxel administration was regarded as a therapy to preserve QOL without a serious side effect and a good compliance of medication. Furthermore, we intend to increase more cases and would like to report them in the future. PMID:15918575

  3. Efficacy of trabectedin in metastatic solitary fibrous tumor

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Solitary fibrous tumor is a rare tumor type and has an unpredictable course. Local recurrence rate varies between 9 and 19 %, and rate of metastatic involvement between 0 and 36 %. It is characterized by a typical architecture and immuno-histochemistry tests. The most important prognostic factor is the complete resection of primary tumor. Treatment of recurrences is not clearly established. If a solitary fibrous tumor is too advanced to allow surgical resection, radiotherapy and chemotherapy may be used. The most often used drugs are doxorubicine andor ifosfamide. We report the case of man with metastatic solitary fibrous tumor treated with trabectedin, administered at a dose of 1.5 mg/m² every 3 weeks. After 3 cycles, metastases had significantly decreased. Recurrence of the disease was demonstrated 8 months after the start of trabectedin. This case shows that trabectedin is a possible treatment option.

    Human vaccines against infectious agents are often effective in a prophylactic setting. However, they are usually not effective when used post-exposure. Rabies vaccine is one of the exceptions, which can be used post-exposure, but is effective only when used in combination with other treatments. Similar results have been obtained with cancer vaccines and immunotherapies. Cancer immunotherapies generally prolong patients' survival when they are used during advanced stage disease. The potential of immunotherapy to cure cancer could be revealed when it is applied in a prophylactic setting. This article provides a brief overview of cancer immunotherapeutics and suggests that immunotherapy can cure cancer if used at the right time against the right target; we suggest that targeting cancer during dormancy in order to prevent tumor recurrence as advanced stage disease is potentially curative.

    Objective: A pilot study to test the feasibility and efficacy of high dose IFO and standard dose ADR and DTIC with G-CSF support in treatment of advanced soft tissue sarcoma (STS). Methods: 35 patients of no prior chemotherapy with metastatic or locally advanced unresectable STS were treated by this regimen, including 18 rhabdomyosarcomas, 7 malignant fibrous histiocytomas, 2 neurofibrosarcomas, 2 fibrosarcomas, 2 leiomyosarcomas, 2 synoviosarcomas, and 2 malignant hemangiopericytomas.IFO dose was 2 g/m2 on day 1-5 (with mesna uroprotection),ADR 50mg/m2 on day 1 and DTIC 250 mg/m2 on day 1-5.G-CSF (2 μg/kg/d) was administered on day 6 to 15 or until recovery of leukocytes account. The cycles were repeated every 3 weeks. Result: There were five complete responses (CR including pathologic CR) and eleven partial responses for overall 46% objective response rate. Most responses were observed within two cycles. The median survival was 15 months. Following CR, two patients remain disease free at 45 and 28 months, respectively. 6/120 (5%) cycles were complicated by grade Ⅳ neutropenia, 46/120 (38%) cycles had grade Ⅲ neutropenia. No patients had treatmentrelated deaths. Nonhematologic toxicity consisted predominantly of anorexia and vomiting. No other severe toxicities were seen, especially no severe cardiotoxicity.Conclusion: This regimen is well tolerated and has substantial benefits for patients with advanced soft tissue sarcomas.

    BACKGROUND The type 3 Dearing reovirus (Reolysin) is a naturally occurring virus that preferentially infects and causes oncolysis in tumor cells with a Ras-activated pathway. It induces host immunity and cell cycle arrest and acts synergistically with cytotoxic agents. METHODS This study evaluated Reolysin combined with paclitaxel and carboplatin in patients with metastatic/recurrent KRAS-mutated or epidermal growth factor receptor (EGFR)–mutated/amplified non–small cell lung cancer. RESULTS Thirty-seven patients were treated. Molecular alterations included 20 KRAS mutations, 10 EGFR amplifications, 3 EGFR mutations, and 4 BRAF-V600E mutations. In total, 242 cycles (median, 4; range, 1-47) were completed. The initial doses were area under the curve (AUC) 6 mg/mL/min for carboplatin, 200 mg/m2 for paclitaxel on day 1, and 3×1010 50% tissue culture infective dose for Reolysin on days 1 to 5 of each 21-day cycle. Because of diarrhea and febrile neutropenia (in the first 2 patients), subsequent doses were reduced to 175 mg/m2 for paclitaxel and AUC 5 mg/mL/min for carboplatin. Toxicities included fatigue, diarrhea, nausea/vomiting, neutropenia, arthralgia/myalgia, anorexia, and electrolyte abnormalities. Response Evaluation Criteria in Solid Tumors 1.0 responses included the following: partial response for 11 patients, stable disease (SD) for 20 patients, progressive disease for 4 patients, and not evaluable for 2 patients (objective response rate, 31%; 90% 1-sided lower confidence interval, 21%). Four SD patients had >40% positron emission tomography standardized uptake value reductions. The median progression-free survival, median overall survival, and 12-month overall survival rate were 4 months, 13.1 months, and 57%, respectively. Seven patients were alive after a median follow-up of 34.2 months; they included 2 patients without disease progression at 37 and 50 months. CONCLUSIONS Reolysin in combination with paclitaxel and carboplatin was well tolerated. The

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

    International Nuclear Information System (INIS)

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

  13. Boron neutron capture therapy for advanced and/or recurrent cancers in the oral cavity

    International Nuclear Information System (INIS)

    This preliminary study of 5 patients with advanced and/or recurrent cancer in the oral cavity was performed to evaluate the effectiveness of Boron Neutron Capture Therapy (BNCT). The patients received therapy with the 10B-carrier p-boronophenylalanine (BPA) with or without borocaptate sodium (BSH) and irradiation thereafter with epithermal neutrons. All underwent 18F-BPA PET studies before receiving BNCT to determine the accumulation ratios of BPA in tumor and normal tissues. The tumor mass was decreased in size and at minimum a transient partial response was achieved in all cases, though rapid tumor re-growth was observed in 2. Although tentative clinical responses and improvements in quality of life were recognized, obliteration of the tumor was not obtained in any of the cases. Additional studies are required to determine the utility and indication of BNCT for oral cancer. (author)

  14. Experience in treatment of patients with locally advanced or recurrent breast cancer. Intraarterial infusion chemotherapy combined with radiotherapy

    International Nuclear Information System (INIS)

    For the purpose of local control and breast conservation, intraarterial infusion chemotherapy combined with radiotherapy has been indicated in patients with locally advanced breast cancer both in primary and recurrent cases. The present series, evaluated during the past 4 years, consisted of 15 patients 35-83 years of age, with invasive ductal carcinoma, including 10 with primary breast cancer (stage IIIb: 1, IV: 9) and 5 with postoperative recurrence (stage IIIb: 2, IV: 3). Intraarterial chemotherapy is started, basically infusing ADM 50 mg, MMC 10 mg and CDDP 50 mg into the internal thoracic and/or subclavian artery 1-3 times, followed by reduction surgery (quadrantectomy: 4, wide resection: 2) and radiotherapy to the breast, supraclavicular, parasternal and cervical regions according to tumor extent. Local response after arterial infusion was CR: 2, PR: 10, NC: 3 (response rate: 73% ). The response rate of distant metastases after arterial infusion was 73%. Of 10 patients with primary breast cancer, recurrence was noted in 1. Breast conservation was successful in 8 of 10 patients. One of them, in stage IIIb, has survived for 4.5 years with no evidence of disease and with breast conservation. Five patients with postoperative recurrence showed CR with no recurrence after intraarterial chemotherapy and radiotherapy. Acute skin reaction occurred in 6 patients, and was especially frequent in patients with postoperative recurrence (4 of 5). According to these results, combined therapy affords breast conservation even in patients with locally advanced breast cancer, and improves patient's QOL in stage IV. (author)

  15. Tolerability of Therapies Recommended for the Treatment of Hormone Receptor-Positive Locally Advanced or Metastatic Breast Cancer.

    For women with hormone receptor-positive advanced breast cancer, endocrine therapies, including the selective estrogen receptor modulator tamoxifen, the aromatase inhibitors anastrozole, letrozole, and exemestane, and the selective estrogen receptor degrader fulvestrant, are recommended in clinical guidelines. The addition of targeted agents such as everolimus or palbociclib to aromatase inhibitors are also recommended as treatment options. Chemotherapy remains an option, although clinical guidelines have recommended these agents be reserved for patients with immediately life-threatening disease or if resistance to endocrine therapy is known or suspected. The present review has consolidated the tolerability profiles of the agents approved for use in the treatment of hormone receptor-positive advanced or metastatic breast cancer based on phase III registration trial data. Endocrine therapies are generally well tolerated, although the addition of targeted therapies to aromatase inhibitors or fulvestrant appears to increase the proportion of patients experiencing adverse events, and palbociclib and chemotherapy appear to be more closely associated with serious adverse events, including neutropenia.

    Past studies have demonstrated that epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors can significantly improve clinical outcomes in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) and sensitive EGFR gene mutations. Gefitinib (Iressa(®)), the first oral EGFR tyrosine kinase inhibitor, has been shown to be more effective and better tolerated than chemotherapy either in first-line or second-line treatment for patients with advanced NSCLC harboring sensitive EGFR mutations. Conversely, among patients with wild-type EGFR, gefitinib is inferior to standard chemotherapy in both the first-line and second-line settings. Further, gefitinib is effective in patients with brain metastases because of its low molecular weight and excellent penetration of the blood-brain barrier. In this review, we summarize the current data from clinical trials with gefitinib and appraise its role in the management of locally advanced or metastatic NSCLC.

    Chemotherapy with cisplatin plus fluorouracil is the current standard treatment for metastatic or recurrent esophageal cancer. We have developed a 2-weekly docetaxel combined with CF regimen and conducted a Phase I/II trial for metastatic or recurrent esophageal cancer (JCOG0807). Promising efficacy and safety were shown in JCOG0807, and we have commenced a Phase III trial in September 2014 to confirm the superiority of 2-weekly DCF to CF for patients with metastatic or recurrent esophageal cancer. A total of 240 patients will be accrued from 41 Japanese institutions over a period of 4 years. The primary end point is overall survival. The secondary end points are progression-free survival, response rate and proportion of adverse events. This trial has been registered in the UMIN Clinical Trials Registry as UMIN000015107 (http://www.umin.ac.jp/ctr/index.htm). PMID:25646357

  1. Phase I study of intermittent and chronomodulated oral therapy with capecitabine in patients with advanced and/or metastatic cancer

    International Nuclear Information System (INIS)

    The combination of capecitabine and gemcitabine at Fixed Dose Rate (FDR) has been demonstrated to be well tolerated, with apparent efficacy in patients with advanced cancers. FDR gemcitabine infusion leads to enhanced intracellular accumulation of drug and possible augmented clinical effect. The goals of this phase I study were to determine the maximum-tolerated dose (MTD) of chronomodulated capecitabine in patients with advanced cancer and to describe the dose-limiting toxicities (DLT), the safety profile of this way of administration. Patients with advanced solid tumours who had failed to response to standard therapy or for whom no standard therapy was available were elegible for this study. Capecitabine was administered orally according to following schedule: 1/4 of dose at 8:00 a.m.; 1/4 of dose at 6:00 p.m. and 1/2 of dose at 11:00 p.m. each day for 14 consecutive days, followed by a 7-day rest period. All 27 patients enrolled onto the study were assessable for toxicity. The most common toxicities during the first two cycles of chemotherapy were fatigue, diarrhoea and hand foot syndrome (HFS). Only one out of the nine patients treated at capecitabine dose of 2,750 mg/m2 met protocol-specified DLT criteria (fatigue grade 4). However, at these doses the majority of cycles of therapy were delivered without dose reduction or delay. No other episodes of DLT were observed at the same dose steps and at the lower dose steps of capecitabine (1,500/1,750/2,000/2,250/2,500 mg/m2). The dose of 2,750 mg/m2 is recommended for further study. Tumor responses were observed in patients with metastatic breast and colorectal cancer. High doses of chronomodulated capecitabine can be administered with acceptable toxicity. The evidence of antitumor activity deserves further investigation in phase II combination chemotherapy studies

    This randomized controlled clinical trial was designed to compare the safety and effectiveness of different sequences of treatment with cisplatin (CDDP) and 5-fluorouracil (5-FU) in patients with unresectable advanced and post-operative recurrent gastric cancer. Patients with unresectable advanced or post-operative recurrent gastric cancer were randomly assigned by a registration center to group A or B. Group A received CDDP (80 mg/m(2)) as a continuous 2-h intravenous infusion on day 1 and 5-FU (700 mg/m(2)) as a continuous intravenous infusion on days 2-5. Group B was given 5-FU (700 mg/m(2)) as a continuous intravenous infusion on days 1-4, followed by CDDP (80 mg/m(2)) as a continuous 2-h intravenous infusion on day 5. Each course of chemotherapy was repeated every 28 days. A total of 74 patients were enrolled. One patient died accidentally, and 5 could not be evaluated. Response was assessable in 68 patients. The response rate was 31.3% (10/32) in group A as compared with 13.9% (5/36) in group B. Although the response rate was higher in Group A, the difference was not significant (p=0.085). The response rate in patients with diffuse type tumors was significantly lower in group B. There was no difference between the groups in response among patients with intestinal type tumors. The median overall survival was 239 and 174 days and time to progression was 175 and 140 days in group A and group B, respectively. Although there were trends toward longer survival and time to progression in group A, the differences between the groups were not statistically significant. There was also no difference in the type or incidence of adverse reactions. The results of this controlled study indicate that the overall response rate was slightly but not significantly higher in patients who received CDDP before 5-FU. Among patients with diffuse type tumors, the response rate was significantly lower when 5-FU was administered before CDDP. Our results suggest that CDDP should be given

    PURPOSE AND METHODS Our secondary analyses compared survival with eribulin versus capecitabine in various patient subgroups from a phase 3, open-label, randomized study. Eligible women aged ≥18 years with advanced/metastatic breast cancer and ≤3 prior chemotherapies (≤2 for advanced/metastatic disease), including an anthracycline and taxane, were randomized 1:1 to intravenous eribulin mesylate 1.4 mg/m2 on days 1 and 8 or twice-daily oral capecitabine 1250 mg/m2 on days 1–14 (21-day cycles). RESULTS In the intent-to-treat population (eribulin 554 and capecitabine 548), overall survival appeared longer with eribulin than capecitabine in various subgroups, including patients with human epidermal growth factor receptor 2-negative (15.9 versus 13.5 months, respectively), estrogen receptor-negative (14.4 versus 10.5 months, respectively), and triple-negative (14.4 versus 9.4 months, respectively) disease. Progression-free survival was similar between the treatment arms. CONCLUSIONS Patients with advanced/metastatic breast cancer and human epidermal growth factor receptor 2-, estrogen receptor-, or triple-negative disease may gain particular benefit from eribulin as first-, second-, and third-line chemotherapies. TRIAL REGISTRATION (PRIMARY STUDY) This study reports the subgroup analyses of eribulin versus capecitabine from a phase 3, open-label, randomized study (www.clinicaltrials.gov; ClinicalTrials.gov identifier: NCT00337103).

    Between 1998 and 2003 we observed 15 women who underwent full thickness chest wall resection (FTCWR) followed by plastic reconstruction for locally recurrent or primary breast cancer. Preoperative symptoms were: pain (5 patients), malodorous ulceration (3 patients), presence of tumour mass (4 patients) and thoracic deformity (2 patients). One patient was asymptomatic. Surgery was partial sternectomy with rib resection in 9 patients, rib resection alone in 5, and total sternectomy in one. No perioperative mortality or major morbidity occurred; minor complications occurred in 3 patients (20%). Five of the six surviving patients reported a positive overall outcome in a telephonic interview. Median overall and disease-free survival were 23.4 and 17.5 months, respectively. In conclusion, FTCWR is a safe procedure with low morbidity and mortality that can provide good symptoms palliation in patients with locally advanced breast malignancies, so it should be considered more often by interdisciplinary care providers in those patients who fail to respond to classic multimodality treatment.

    2013-01-01

    Chemotherapy, endocrine therapy and molecular targeted therapy are vital means in the treatment of metastatic breast cancer (MBC), whose reasonable and standard applications are of great importance to prolong patients’ survival and improve the quality of life. The expressions of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER-2) present signiifcant differences between primary and metastatic breast cancer. However, these differences may affect the selection of MBC patients for therapeutic strategies and judgment on the prognosis. Hence, the relevant researches on variations of hormone receptors and HER-2 in primary and metastatic breast cancer, discordant causes of ER, PR and HER-2 expression in primary and metastatic lesions and clinical value of biopsy to the metastases are reviewed in the study.

    The FDA-approved starting dosage of capecitabine is 1,250 mg/m(2), and market research indicates that U.S. physicians routinely prescribe 1,000 mg/m(2). Retrospective analyses however report reduced toxicity and efficacy in a subset of patients with the 3R/3R genotype of the thymidylate synthase gene enhancer region (TSER). This study sought to develop TSER genotype-specific guidelines for capecitabine dosing. Capecitabine was dose-escalated in advanced and/or metastatic cancer patients with TSER 3R/3R (Group A; N = 18) or 2R/2R + 2R/3R (Group B; N = 5) from 1,250 to 1,625 mg/m(2) b.i.d., every 2 weeks on/1 week off for up to 8 cycles. Parent and metabolites pharmacokinetics, adverse events, and tumour response were assessed. The maximum tolerated and recommended doses in 3R/3R patients are 1,625 mg/m(2) and 1,500 mg/m(2). At 1,500 mg/m(2), one in nine 3R/3R patients experienced a dose-limiting toxicity. Dosing guidelines for 2R/2R + 2R/3R remain undetermined due to poor accrual. The results indicate that 3R/3R patients may be amenable to 1,500 mg/m(2) b.i.d. on an intermittent schedule, and is the first to prospectively validate the utility of TSER pharmacogenetic-testing before capecitabine treatment.

  12. Tumor recurrence and in-field control after multimodality treatment of locally advanced esophageal cancer

    International Nuclear Information System (INIS)

    Purpose: Neoadjuvant chemoradiotherapy is used prior to surgery in curative treatment of esophageal cancer (EC). We evaluated the in-field control of this multimodal treatment by extraction of radiation dose parameters and determination of the spatial relation between tumor recurrence location(s) and radiation target volume (RTV). Methods and materials: Treatment consisted of neoadjuvant chemotherapy (5-FU and cisplatin) and radiotherapy (36 Gy) followed by Ivor–Lewis esophagectomy. For patients with locoregional recurrence(s), image fusion was performed between radiotherapy planning CT and follow-up CT(s). A region-of-interest was contoured on the planning CT around each locoregional recurrence. Mean and maximum radiation doses were then extracted to classify recurrences as out-of-field, marginal or in-field. Results: Eighty patients were included. The median follow-up duration was 19 months. Fifteen of 95 locoregional recurrences were detected in the RTV. These in-field relapses occurred in only 6 patients (7.8%) on 12 different anatomical locations. None of the patients with in-field failure had a pCR and all had concurrent distant failure on multiple anatomical sites. Conclusion: Neoadjuvant chemoradiotherapy followed by Ivor–Lewis esophagectomy yields excellent in-field control, as only a clear minority (7.8%) of patients developed a relapse in the RTV. In-field recurrence is associated with widespread tumor dissemination and poor pathological response to neoadjuvant treatment

  14. Local recurrence, rate and sites of metastases, and time to relapse as a function of treatment regimen, size of primary and surgical history in 62 patients presenting with non-metastatic Ewing's sarcoma of the pelvic bones

    International Nuclear Information System (INIS)

    This report reviews the experience of 62 patients who presented between 1972 and 1978 with non-metastatic Ewing's sarcoma of the pelvis and were entered on IESS I. Seventeen patients (27%) developed a local recurrence, 38 patients (61%) demonstrated metastases and 21 (34%) neither. In the dose range 4000 rad to 6000 rad no dose response could be detected for local control of tumor. Forty-six patients (74%) had a biopsy or exploratory surgery only, 5 patients (8%) had an incomplete resection and 11 patients (18%) has a complete resection of their tumor. In the 46 patients having a biopsy only, 13 developed a local recurrence (28%) as compared to 2 of 11 patients undergoing a complete resection (18%). The most common sites for metastases were lung in 19 patients (31%) and bone in 23 patients (37%). No significant difference was noted in the frequency of overall metastases or metastases to any site between those patients receiving one of the three treatment regimens used in IESS I: VAC and Adriamycin (regime I), VAC alone (regimen II) and VAC plus bilateral pulmonary irradiation (regimen III). At a median follow-up of 135 weeks no significant difference in median survival could be detected in patients with pelvic primaries between regimens I, II and III. The possible reasons for the poor prognosis of pelvic primary patients are discussed together with treatment policies that might improve the survival of this group of patients

    Survival for extensive recurrent squamous cell carcinomas of the head and neck remains poor, with the major cause of death being local recurrence. Surgical implantation of iodine-125 interstitial seeds allows tumoricidal doses of radiation to be delivered to residual tumor while minimizing radiation doses to the surrounding tissues. From 1978 to 1988, 39 implantations were performed on 35 patients for extensive recurrent squamous cell carcinoma of the head and neck. The decision for implantation was based on positive margins or close to resection margins from frozen sections after salvage resection. The determinate 5-year disease-free survival was 41%, with both the overall and no evidence of disease 5-year survivals being 29%. Significant complications occurred in 36% of all cases. This figure increased to 56% when flap reconstruction was required. Possible reasons for this seemingly high complication rate are discussed. Considering the advanced nature of these recurrent carcinomas, surgical resection with iodine-125 seed implantation appears to be an effective method of managing disease that might otherwise be judged unresectable and treated for palliation only.

    Objective: This is a retrospective study to assess the effectiveness of consolidation radiotherapy (CRT) following palliative chemotherapy in patients with metastatic or locally advanced non-small cell lung cancer (NSCLC) who are not suitable for radical treatment. Methods: This study involved retrospective analysis of a prospective database of Northampton Oncology Centre from January 2005 to December 2010,63 patients with advanced/metastatic NSCLC treated at the oncology centre were enrolled. Patients were either treated with high dose (39/36 Gy /13-12 fractions, group 1) or low dose (20 Gy / 5 fractions, group 2) CRT or those were not offered any CRT (group 3). Results: There was no significant difference between the three groups as regard age, sex, performance status, comorbidities or chemotherapy given. However there was a statistically significant difference as regard the stage P = 0.009 with more stage IV patients at group Ⅱ and Ⅲ compared to group l. The mean survival for the three groups was 27 months, 14 months &15 months, respectively. There was a statistically significant improvement of survival in patients treated with high dose palliative CRT compared to the other two groups (P = 0.006). In multivariate analysis only the radiotherapy dose remains as the only statistical significant factor affecting the survival with hazard ratio 0.372 and confidence interval (0.147-0.726). Conclusion: Despite the limitation of our retrospective study, it is worth considering CRT approach for patients with advanced and metastatic NSCLC - not suitable for radical treatment - who have not progressed on chemotherapy.

    Full Text Available Metastases to the spine can involve the bone, epidural space, leptomeninges, and spinal cord. The spine is the third most common site for metastatic disease, following the lung and the liver. Approximately 60–70% of patients with systemic cancer will have spinal metastasis. Materials/Methods. This is a review of the imaging techniques and typical imaging appearances of spinal metastatic disease. Conclusions. Awareness of the different manifestations of spinal metastatic disease is essential as the spine is the most common site of osseous metastatic disease. Imaging modalities have complimentary roles in the evaluation of spinal metastatic disease. CT best delineates osseous integrity, while MRI is better at assessing soft tissue involvement. Physiologic properties, particularly in treated disease, can be evaluated with other imaging modalities such as FDG PET and advanced MRI sequences. Imaging plays a fundamental role in not only diagnosis but also treatment planning of spinal metastatic disease.

Gefitinib (Iressa®, the first oral EGFR tyrosine kinase inhibitor, has been shown to be more effective and better tolerated than chemotherapy either in first-line or second-line treatment for patients with advanced NSCLC harboring sensitive EGFR mutations. Conversely, among patients with wild-type EGFR, gefitinib is inferior to standard chemotherapy in both the first-line and second-line settings. Further, gefitinib is effective in patients with brain metastases because of its low molecular weight and excellent penetration of the blood–brain barrier. In this review, we summarize the current data from clinical trials with gefitinib and appraise its role in the management of locally advanced or metastatic NSCLC.Keywords: gefitinib, non-small cell lung cancer, epidermal growth factor receptor, tyrosine kinase inhibitor

    International Nuclear Information System (INIS)

    Differentiating recurrence of glioma from radiation-induced brain injury is a central challenge in neuro-oncology. The 2 very different outcomes after brain tumor treatment often appear similar on traditional imaging studies. They may even manifest with similar clinical symptoms. Distinguishing treatment injury from tumor recurrence is crucial for diagnosis and treatment planning. In this article, we reviewed the latest developments and key findings from research studies exploring the efficacy of structural and functional imaging modalities in differentiating treatment injury from tumor recurrence with DWI, MRS, DCE-MR, DSC-MR, PET, and SPECT. And we discussed the advantages and disadvantages of each approach to provide useful information for making proper diagnosis and treatment planning. (authors)

    Chronic hepatitis C virus (HCV) infection with advanced cirrhosis or post‐liver transplantation recurrence represents a high unmet medical need with no approved therapies effective across all HCV genotypes. The open‐label ALLY‐1 study assessed the safety and efficacy of a 60‐mg once‐daily dosage of daclatasvir (pan‐genotypic NS5A inhibitor) in combination with sofosbuvir at 400 mg once daily (NS5B inhibitor) and ribavirin at 600 mg/day for 12 weeks with a 24‐week follow‐up in two cohorts of patients with chronic HCV infection of any genotype and either compensated/decompensated cirrhosis or posttransplantation recurrence. Patients with on‐treatment transplantation were eligible to receive 12 additional weeks of treatment immediately after transplantation. The primary efficacy measure was sustained virologic response at posttreatment week 12 (SVR12) in patients with a genotype 1 infection in each cohort. Sixty patients with advanced cirrhosis and 53 with posttransplantation recurrence were enrolled; HCV genotypes 1 (76%), 2, 3, 4, and 6 were represented. Child‐Pugh classifications in the advanced cirrhosis cohort were 20% A, 53% B, and 27% C. In patients with cirrhosis, 82% (95% confidence interval [CI], 67.9%‐92.0%) with genotype 1 infection achieved SVR12, whereas the corresponding rates in those with genotypes 2, 3, and 4 were 80%, 83%, and 100%, respectively; SVR12 rates were higher in patients with Child‐Pugh class A or B, 93%, versus class C, 56%. In transplant recipients, SVR12 was achieved by 95% (95% CI, 83.5%‐99.4%) and 91% of patients with genotype 1 and 3 infection, respectively. Three patients received peritransplantation treatment with minimal dose interruption and achieved SVR12. There were no treatment‐related serious adverse events. Conclusion: The pan‐genotypic combination of daclatasvir, sofosbuvir, and ribavirin was safe and well tolerated. High SVR rates across multiple HCV genotypes were achieved by patients with

  8. Recent advances in technologies for the detection of occult metastatic cells in bone marrow of breast cancer patients

    International Nuclear Information System (INIS)

    Approximately half of breast cancer patients with stage I–III disease will suffer metastatic disease despite resection with tumour-free margins. In 30–40% of these patients, individual carcinoma cells can already be detected at the time of primary therapy in cytological bone marrow preparations using immunocytochemistry. Numerous prospective clinical studies have shown that the presence of occult metastatic cells in bone marrow is prognostically relevant to patient survival. Only a few studies failed to do so, thus stimulating a critical discussion on the methodology and clinical value of bone marrow analysis. The potential for obtaining improved prognostic information on patient outcome, for monitoring tumour cell eradication during adjuvant and palliative systemic therapy, and for specifically targeting tumour biological therapies are intriguing clinical opportunities that may be afforded by bone marrow analysis. Standardized and robust methodology is a prerequisite for clinical application of these techniques, however

    We report here the effectiveness of chemoradiotherapy for a patient with local recurrence followed by curable gastrectomy. A 57-year-old man presented with a history of total gastrectomy with distal pancreatectomy and splenectomy, D2 lymphadenectomy, and Roux-en-Y reconstruction for advanced gastric cancer arising from the cardia. Esophageal intramural metastasis and lymph node metastasis around the right recurrent nerve were detected by chest-abdominal computed tomography and gastrointestinal endoscopy 27 months after the initial gastrectomy. Stable disease was achieved following 7 courses of chemotherapy using S-1 plus CDDP. Concurrent chemoradiotherapy including administration of S-1 and radiation of total 50 Gy (2 Gy/25 Fr) was selected for local tumor control. The patient was not able to eat solid food because of esophageal stenosis from regrowth of intramural metastasis of the esophagus 60 months after the chemotherapy. A WallFlex™ Duodenal Stent was placed to improve the dysphagia 67 months after chemotherapy. The patient died from recurrence of gastric cancer 69 months after completion of the initial chemotherapy and 2 months after the stent insertion.

    Full Text Available Background and objective Icotinib hydrochloride is the third single target EGFR-TKI used in clinical treatment of advanced non-small cell lung cancer (NSCLC. Clinical research reports on its efficacy and survival in patients with Recurrent Advanced NSCLC are still little.The aim of this study is to evaluate the efficacy and survival of Icotinib hydrochloride for patients with advanced non-small cell lung cancer who failed to previous chemotherapy and explore the association of clinical features with the efficacy and survival. Methods The clinical data of 60 NSCLC patients referred to the Beijing Chest Hospital, Capital Medical University from March 2009 to July 2012 were retrospectively analyzed. Results The overall response rate (ORR was 45.0% and the disease control rate (DCR was 80.0%. The median progression-free survival (PFS time was 6.7 months. RR and PFS in female were superior to male (P=0.014, 0.013, respectively. RR, DCR in 2nd-line subgroup were superior to ≥3rd-line subgroup (P=0.020, 0.024, respectively. RR, DCR and PFS in EGFR mutation carriers were significantly superior to wild-type patients (P=0.006, <0.001, 0.002, respectively . There was no statistical difference in RR and PFS between those age <65 and ≥65 or PS<2 and PS≥2. There was no statistical difference in RR and DCR between exon 19 deletion and exon 21 mutations, while the former had much longer PFS (P=0.020. EGFR mutation and exon 19 deletion are the independent prognostic factors to significantly improve the PFS (P=0.009, 0.012, respectively. The side effects were generally mild and consisted of rash and diarrhea. Conclusion Icotinib hydrochloride is effective especially in EGFR mutation carriers and well tolerated in patients with recurrent advanced non-small-cell lung cancer.

  13. Prediction of sensitivity to anticancer agents for patients with advanced or recurrent breast cancer by Tc-99m sestamibi

    International Nuclear Information System (INIS)

    Tc-99m Sestamibi (99mTc-MIBI) is known to be a substrate of P-glycoprotein (P-gp) that effluxes the drugs out of cancer cells. The overexpression of P-gp involved in multidrug resistance phenomenon in patients with advanced or recurrent breast cancers was shown in the plasma membrane of breast cancer cells. In this study, we examined the usefulness of 99mTc-MIBI scintigraphy for the prediction of sensitivity to anticancer agents in 8 cases with advanced or recurrent breast cancer. The retrospective analysis showed that the sensitivity to the chemotherapy could be evaluated in 3 cases by 99mTc-MIBI scintigraphy, but in the other 5 cases 99mTc-MIBI scintigraphy was not eligible for the prediction of sensitivity. Two out of 3 cases showed over 50% in reduction rate of target tumors (PR) with higher accumulation of 99mTc-MIBI, while another case with PD showed lower. These results suggest that the accumulation of 99mTc-MIBI could be associated with the sensitivity to P-gp-related anticancer agents, and that the functional analysis of P-gp by 99mTc-MIBI might be useful for the prediction of responsiveness of chemotherapy in patients with breast cancer.

    Given the bone tropism of prostate cancer, conventional imaging modalities poorly identify or quantify metastatic disease. {sup 89}Zr-huJ591 positron emission tomography (PET) imaging was performed in patients with metastatic prostate cancer to analyze and validate this as an imaging biomarker for metastatic disease. The purpose of this initial study was to assess safety, biodistribution, normal organ dosimetry, and optimal imaging time post-injection for lesion detection. Ten patients with metastatic prostate cancer received 5 mCi of {sup 89}Zr-huJ591. Four whole-body scans with multiple whole-body count rate measurements and serum activity concentration measurements were obtained in all patients. Biodistribution, clearance, and lesion uptake by {sup 89}Zr-huJ591 immuno-PET imaging was analyzed and dosimetry was estimated using MIRD techniques. Initial assessment of lesion targeting of {sup 89}Zr-huJ591 was done. Optimal time for imaging post-injection was determined. The dose was well tolerated with mild chills and rigors seen in two patients. The clearance of {sup 89}Zr-huJ591 from serum was bi-exponential with biological half-lives of 7 ± 4.5 h (range 1.1-14 h) and 62 ± 13 h (range 51-89 h) for initial rapid and later slow phase. Whole-body biological clearance was 219 ± 48 h (range 153-317 h). The mean whole-body and liver residence time was 78.7 and 25.6 h, respectively. Dosimetric estimates to critical organs included liver 7.7 ± 1.5 cGy/mCi, renal cortex 3.5 ± 0.4 cGy/mCi, and bone marrow 1.2 ± 0.2 cGy/mCi. Optimal time for patient imaging after injection was 7 ± 1 days. Lesion targeting of bone or soft tissue was seen in all patients. Biopsies were performed in 8 patients for a total 12 lesions, all of which were histologically confirmed as metastatic prostate cancer. One biopsy-proven lesion was not positive on {sup 89}Zr-huJ591, while the remaining 11 lesions were {sup 89}Zr-huJ591 positive. Two biopsy-positive nodal lesions were noted only on

  17. C-reactive protein in patients with advanced metastatic renal cell carcinoma: Usefulness in identifying patients most likely to benefit from initial nephrectomy

    International Nuclear Information System (INIS)

    C-reactive protein (CRP) is considered a useful serum marker for patients with RCC. However, its clinical utility in advanced metastatic renal cell carcinoma (AM-RCC), particularly in deciding whether to perform nephrectomy at the onset, is not well studied. We retrospectively evaluated 181 patients with AM-RCC, including 18 patients underwent potentially curative surgery, 111 underwent cytoreductive nephrectomy, and 52 received medical treatment only. CRP cutoff points were determined by receiver operating characteristic (ROC) curve analysis. Kaplan-Meier and Cox regression analyses were used for survival tests. ROC analysis suggested that grouping patients according to 3 CRP ranges was a rational model. Patients with highly elevated CRP (≥67.0 mg/L) presented remarkably poor prognosis despite treatment (nephrectomy or medical treatment only). Cox regression models demonstrated that risk factors of overall survival for patients who underwent nephrectomy were the CRP ranges defined in this study (≤18.0 mg/L, >18.0 and <67.0 mg/L, and ≥67.0 mg/L), ECOG PS (0, 1, and ≥2), and number of metastatic organ sites (0–1 and ≥2). The retrospective design is a limitation of this study. Our study demonstrated that the serum CRP level is a statistically significant prognostic parameter for patients with AM-RCC. The data also indicated that pretreatment serum CRP level provides useful prognostic information that helps in deciding whether to perform initial nephrectomy for patients with AM-RCC

  18. Examestane in advanced or recurrent endometrial carcinoma: a prospective phase II study by the Nordic Society of Gynecologic Oncology (NSGO)

    International Nuclear Information System (INIS)

    We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estrogen receptor (ER) positive and ER negative patients. Recruitment to the ER negative group was stopped prematurely after 12 patients due to slow accrual. In the ER positive patients, we observed an overall response rate of 10%, and a lack of progression after 6 months in 35% of the patients. No responses were registered in the ER negative patients, and all had progressive disease within 6 months. For the total group of patients, the median progression free survival (PFS) was 3.1 months (95% CI: 2.0-4.1). In the ER positive patients the median PFS was 3.8 months (95% CI: 0.7-6.9) and in the ER negative patients it was 2.6 months (95% CI: 2.1-3-1). In the ER positive patients the median overall survival (OS) time was 13.3 months (95% CI: 7.7-18.9), in the ER negative patients the corresponding numbers were 6.1 months (95% CI: 4.1-8.2). Treatment with exemestane was well tolerated. Treatment of estrogen positive advanced or recurrent endometrial cancer with exemestane, an aromatase inhibitor, resulted in a response rate of 10% and lack of progression after 6 months in 35% of the patients.

    2015-01-01

    Full Text Available Regorafenib is a novel oral multitargeted tyrosine kinase inhibitor having both antitumor and anti-angiogenic activities. Regorafenib was recently approved by US Food and Drug Administration in February 25, 2013 in the treatment for patients with advanced gastrointestinal stromal tumor and for the treatment of patients with metastatic colorectal carcinoma after disease progression or intolerance to imatinib mesylate and sunitinib therapy. Oral regorafenib demonstrates a high level of efficacy with acceptable tolerability with the 160 mg daily for 3 weeks followed by 1 week off schedule; a continuous schedule could be of interest. Hypertension, mucositis, hand foot skin reaction, diarrhea and asthenia are the most common side-effects. Regardless of these encouraging results, studies investigating, adjuvant and neoadjuvant settings are awaited, as well as trials using regorafenib in combination with chemotherapy or other targeted therapies. Clinical trials investigating regorafenib in other tumor types are ongoing.

    Background Studies have shown that irinotecan can improve survival in patients with advanced or recurrent gastric cancer,but the overall benefit of irinotecan in the treatment of advanced or recurrent gastric cancer remains controversial.The aim of this study was to evaluate the benefits and risks of irinotecan for survival in patients with advanced or recurrent gastric cancer.Method We searched PubMed,EmBase,the Cochrane Central Register of Controlled Trials,reference lists of articles,and proceedings of major conferences for relevant clinical trials.We included randomized controlled trials that reported on the efficacy and safety of irinotecan in patients with advanced or recurrent gastric cancer.Outcomes were analyzed by survival rate,objective response rate (ORR),and toxicity.Furthermore,the analysis was further stratified by factors that could affect the treatment effects.Results Eight trials recruiting 1 546 patients with advanced or recurrent gastric cancer were included in the analysis.Overall,irinotecan therapy was associated with a 6% improvement in survival rate,but this difference was not statistically significant (odds ratio (OR) 0.94; 95% confidence interval (95% CI) 0.70-1.27; P=-0.69).However,irinotecan therapy had more frequent ORR than irinotecan-free arm (OR 1.70; 95% CI 1.34-2.17; P <0.001).Furthermore,irinotecan therapy was associated with a clinically and statistically significant increase in the risk for declined hemoglobin,hyponatremia,and diarrhea,but it also protected against thrombocytopenia risk when compared with irinotecan-free therapy.Conclusions There is no evidence to support the use of irinotecan therapy in patients with advanced or recurrent gastric cancer; however,given the significant advantage in ORR irinotecan therapy using combination regimens may be considered for further evaluation in subsets of patients who may benefit from this treatment.

  2. 3'-Deoxy-3'-18F-fluorothymidine positron emission tomography as an early predictor of disease progression in patients with advanced and metastatic pancreatic cancer

    International Nuclear Information System (INIS)

    3'-Deoxy-3'-18F-fluorothymidine (FLT) positron emission tomography (PET) has limited utility in abdominal imaging due to high physiological hepatic uptake of tracer. We evaluated FLT PET/CT combined with a temporal-intensity information-based voxel-clustering approach termed kinetic spatial filtering (FLT PET/CTKSF) for early prediction of response and survival outcomes in locally advanced and metastatic pancreatic cancer patients receiving gemcitabine-based chemotherapy. Dynamic FLT PET/CT data were collected before and 3 weeks after the first cycle of chemotherapy. Changes in tumour FLT PET/CT variables were determined. The primary end point was RECIST 1.1 response on contrast-enhanced CT after 3 months of therapy. Twenty patients were included. Visual distinction between tumours and normal pancreas was seen in FLT PETKSF images. All target lesions (>2 cm), including all primary pancreatic tumours, were visualised. Of the 11 liver metastases, 3 (<2 cm) were not visible after kinetic filtering. Of the 20 patients, 7 progressed (35 %). Maximum standardised uptake value at 60 min post-injection (SUV60,max) significantly increased in patients with disease progression (p = 0.04). Receiver-operating characteristic curve analysis indicated that a threshold of SUV60,max increase of ≥ 12 % resulted in sensitivity, specificity and positive predictive value (PPV) of 71, 100 and 100 %, respectively [area under the curve (AUC) 0.90, p = 0.0001], to predict patients with disease progression. Changes in SUV60,max were not predictive of survival. FLT PET/CT detected changes in proliferation, with early increase in SUV60,max predicting progressive disease with a high specificity and PPV. Therefore, FLT PET/CT could be used as an early response biomarker for gemcitabine-based chemotherapy, to select a poor prognostic group who may benefit from novel therapeutic agents in advanced and metastatic pancreatic cancer.

    Pemetrexed, a novel multi-targeted agent established for the treatment of mesothelioma, has been under investigation for other malignancies, and in recent years particularly for non-small-cell lung cancer (NSCLC). In the present trial we investigated pemetrexed in combination with paclitaxel as front-line treatment in advanced or metastatic NSCLC. Our objectives were to determine the response rate, median and overall survival and toxicity. From April 2005 until May 2006, 51 patients with advanced or metastatic NSCLC were enrolled and 48 were considered evaluable. There were 39 males and nine females, median age 62 years (range 37-81 years), one patient stage IIIA N(2), 23 patients, IIIB and 24, stage IV. All patients had a cytologically- or histologically-confirmed diagnosis. Pemetrexed was administered at a standard dose of 500mg/m(2) and paclitaxel at an escalating dose starting at 135mg/m(2), then 150mg/m(2) and ending at a dose of 175mg/m(2); the level was increased every three patients. Both agents were administered on day 1, repeated every 3 weeks for six courses. A 39.6% partial response rate was observed with a median survival of 14 months. Toxicity was mild with 8.3% grade 3 and 4 neutropenia and other very mild hematologic and non-hematologic adverse reactions. The combination of pemetrexed and paclitaxel at doses of 500mg/m(2) and 175mg/m(2), respectively, has been shown to be an effective combination with very limited toxicity. PMID:17382431

  4. Feasibility study of DCs/CIKs combined with thoracic radiotherapy for patients with locally advanced or metastatic non-small-cell lung cancer

    International Nuclear Information System (INIS)

    The combination of dendritic cells (DCs) and cytokine-induced killer cells (CIKs) can induce the anti-tumor immune response and radiotherapy may promote the activity. We aimed to explore the feasibility of DCs/CIKs combined with thoracic radiotherapy (TRT) for patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). In this study, patients with unresectable stage III/IV NSCLC and an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0–2 and previously receiving two or more cycles of platinum-based doublet chemotherapy without disease progression received TRT plus DCs/CIKs or TRT alone until disease progression or unacceptable toxicity. The primary endpoint was median progression-free survival (mPFS). In treatment group, patients received four-cycle autologous DCs/CIKs infusion starting from the 6th fraction of irradiation. From Jan 13, 2012 to June 30, 2014, 82 patients were enrolled, with 21 patients in treatment group and 61 in control group. The mPFS in treatment group was longer than that in control group (330 days vs 233 days, hazard ratio 0.51, 95 % CI 0.27–1.0, P < 0.05), and the objective response rate (ORR) of treatment group (47.6 %) was significantly higher that of control group (24.6 %, P < 0.05). There was no significant difference in disease control rate (DCR) and median overall survival (mOS) between two groups (P > 0.05). The side effects in treatment group were mild and there was no treatment-related deaths. The combination of DCs/CIKs with TRT could be a feasible regimen in treating locally advanced or metastatic NSCLC patients. Further investigation of the regimen is warranted

Patients and methods: Adult women diagnosed with stage III or IV breast cancer (index date between 2008 and 2012 were identified from MarketScan® databases containing medical and pharmacy claims for >40 million enrollees insured with >100 US health plans. Patients were followed until the earlier of the following: end of enrollment, inpatient death, or December 31, 2012. Study cohorts were women ± HER2-targeted agent use, HER2-targeted agent users' subgroups of stages III and IV, and age group. Pre- and postindex breast cancer treatments were compared among study cohorts. Overall survival was compared using log-rank tests. Cox proportional-hazards models were used to study the predictors of overall survival. Results: Of 30,660 eligible women, 14.4% received HER2-targeted agents. HER2-targeted agent users received more aggressive pre- and postindex cancer treatments compared to those with no HER2-targeted agents. HER2-targeted agents had higher rates of pre- and postindex breast cancer surgery, adjuvant/neoadjuvant chemotherapy, radiation therapy, chemotherapy, and biologics-based therapy. Among HER2-targeted agent users, younger women and those with stage III breast cancer received more aggressive treatments. After adjusting for clinically relevant patient characteristics, women receiving HER2-targeted agents had a 20% reduced risk of death compared to patients not receiving HER2-targeted agents.

    Full text: Superficial hyperthermia in combination with radiotherapy represents very effective local treatment of locally recurrent breast cancer. We will present a group of patients treated in our institution since February 2003 to November 2004. The aim of this work is the evaluation of local response to the treatment in our group of patients. Since February 2003 to November 2004 we treated group of 32 women with locally recurrent breast cancer. 24 patients were treated for local recurrence, 5 patients were treated for supraclavicular lymph node metastasis and 3 patients were treated for locally advanced tumor. 27 patients were evaluable for local response and its duration. Hyperthermia was combined with radiotherapy. Radiotherapy was done on 6 MeV linear accelerator, usually using 2 tangential fields with wedges. Dose of radiotherapy was usually 50 Gy/25 fractions (only in the cases of reirradiation with large volume we applied 40 Gy/20 fr). Hyperthermia was done using Lund hyperthermia system for superficial microwave hyperthermia working on 434 MHz and was applied once a week, 5 to 6 applications during the course of radiotherapy, mainly immediately after radiotherapy, for 60 min. The temperature was measured using termistor probes superficially, minimally in the six points. We tried to achieve temperatures in the range from 42 to 43.5oC, but the actually measured temperatures were limited by the tolerance of patients. The anesthetics were not used. We achieved response in 26 from 27 patients. CR on the chest wall or in the supraclavicular region was achieved in 17 cases, PR in 9 cases and in 1 case was seen only stabilization of disease. Duration of response was in range from 3 to 24 months, with median of 9 months. We did not see any serious side effects resulting from hyperthermia treatment, only in the cases of reirradiation we observed slower healing of the post irradiation skin reaction. Superficial hyperthermia represents useful tool for the

    Full Text Available Purpose: Stereotactic ablative radiotherapy (SABR is an attractive modality to treat malignancies invading the skull base as it can deliver a highly conformal dose with minimal toxicity. However, variation exists in the prescribed dose and fractionation. The purpose of our study is to examine the local control, survival and toxicities in SABR for the treatment of malignant skull base tumors. Methods and Materials: A total of 31 patients and 40 locally-advanced or recurrent head and neck malignancies involving the skull base treated with a common SABR regimen which delivers a radiation dose of 44 Gy in 5 fractions from January 1st, 2004 to December 31st, 2013 were retrospectively reviewed. The local control rate (LC, progression-free survival rate (PFS, overall survival rate (OS and toxicities were reported.Results: The median follow-up time of all patients was 11.4 months (range: 0.6-67.2 months. The median tumor volume was 27 cm3 (range: 2.4-205 cm3. All patients received prior EBRT with a median radiation dose of 64 Gy (range: 24-75.6 Gy delivered in 12 to 42 fractions. 20 patients had surgeries prior to SABR. 19 patients received chemotherapy. Specifically, 8 patients received concurrent cetuximab (ErbituxTM with SABR. The median time-to-progression (TTP was 3.3 months (range: 0-16.9 months. For the 29 patients (93.5% who died, the median time from the end of first SABR to death was 10.3 months (range: 0.5-41.4 months. The estimated 1-year overall survival (OS rate was 35%. The estimated 2-year OS rate was 12%. Treatment was well-tolerated without grade 4 or 5 treatment-related toxicities.Conclusions: SABR has been shown to achieve low toxicities in locally-advanced or recurrent, previously irradiated head and neck malignancies invading the skull base.

    Full Text Available Abstract Background To evaluate whether weekly schedules of docetaxel-based chemotherapy were superior to 3-weekly ones in terms of quality of life in locally advanced or metastatic breast cancer. Methods Patients with locally advanced or metastatic breast cancer, aged ≤ 70 years, performance status 0-2, chemotherapy-naive for metastatic disease, were eligible. They were randomized to weekly or 3-weekly combination of docetaxel and epirubicin, if they were not treated with adjuvant anthracyclines, or docetaxel and capecitabine, if treated with adjuvant anthracyclines. Primary end-point was global quality of life change at 6-weeks, measured by EORTC QLQ-C30. With two-sided alpha 0.05 and 80% power for 35% effect size, 130 patients per arm were needed. Results From February 2004 to March 2008, 139 patients were randomized, 70 to weekly and 69 to 3-weekly arm; 129 and 89 patients filled baseline and 6-week questionnaires, respectively. Global quality of life was better in the 3-weekly arm (p = 0.03; patients treated with weekly schedules presented a significantly worsening in role functioning and financial scores (p = 0.02 and p Conclusions In this trial, the weekly schedules of docetaxel-based chemotherapy appear to be inferior to the 3-weekly one in terms of quality of life in patients with locally advanced or metastatic breast cancer.

    Capecitabine (Xeloda), Roche Laboratories Inc., Nutley, NJ) is an orally administered fluoropyrimidine carbamate that serves as a prodrug of 5-fluorouracil (5-FU), an integral component of chemotherapy (CT) regimens for metastatic colorectal cancer (mCRC). As the drug is orally administered, capecitabine permits greater convenience and flexibility in dosing by eliminating the need for continuous infusion and its potential complications. In phase 3 trials, capecitabine has been used as an alternative to 5-FU, both as a monotherapy and in combination with agents such as oxaliplatin (as XELOX), with good efficacy and tolerability. Combination therapy with capecitabine and irinotecan (XELIRI), however, has produced more variable results, with some dose combinations and schedules resulting in excessive and/or unexplained treatment-related toxicity. Recent initiatives using lower doses of capecitabine and irinotecan, as well as alternative dosing schedules, have resulted in more favorable outcomes (efficacy and tolerability), even in combination with targeted-agents such as bevacizumab. Dose reduction in elderly populations and in those with moderate renal impairment also appears to be important for minimizing toxicity with XELIRI regimens. Although additional phase 3 studies are needed, XELIRI may be an effective base CT regimen, allowing a greater number of treatment options for tumor control in patients with mCRC.

    Full Text Available Background and objective Since the poor outcome for advanced lung cancer with first-line chemotherapy, more efforts should be paid for treatment of advanced recurrent or metastasis non-small cell lung cancer (NSCLC patients. Pemetrexed, as a multi-target antifolate chemotherapeutic drug, was approved for the second-line treatment of advanced NSCLC. The aim of this study is to evaluate the efficacy and side effects of pemetrexed combined with cisplatin/carboplatin in the treatment of advanced recurrent or metastasis NSCLC. Methods Sixty-three advanced recurrent or metastasis NSCLC patients confirmed with pathology or cytology were enrolled in this study. Among them, 40 cases were male and 23 were female, with 62 years of median age. The combination regimen was patients received pemetrexed 500 mg/m2 on day 1 and cisplatin 30 mg/m2 on day 1, day 2 and day 3 or carboplatin 300 mg/m2 on day 1 by intravenous infusion, with 21 days as one cycle. All patients who received 2 or more cycles could be evaluated. Results Only 1 case got complete response, with 5 cases partial response, 36 stable and 21 cases progressive. The overal control rate was 66.7% (42/63. The median survival time was 9.0 months, while the median progression-free survival was 5.0 months (3.0 months in squamous cell carcinoma; 5.5 months in adenocarcinoma. There was a significant difference between squamous cell carcinoma and adenocarcinoma (P=0.017. The common adverse effects were leucopenia, anemia and gastrointestinal response. Conclusion Pemetrexed combined with cisplatin/carboplatin is effective and feasible for advanced recurrent or metastasis NSCLC.

    Purpose: To assess the technical feasibility and toxicity of combined operation and perioperative intensity-modulated fractionated interstitial brachytherapy (IMBT) in advanced-stage malignancies involving the skull base with the goal of preserving the patients' senses of sight. Patients and Methods: This series consisted of 18 consecutive cases: ten patients with paranasal sinus carcinomas, five with sarcomas, two with primitive neuroectodermal tumors (PNETs), and one with parotid gland carcinoma. After, in most cases, subtotal surgical resection (R1-R2: carried out so that the patients' senses of sight were preserved), two to twelve (mean five) afterloading plastic tubes were placed into the tumor bed. IMBT was performed with an iridium-192 stepping source in pulsed-dose-rate/high-dose-rate (PDR/HDR) afterloading technique. The total IMBT dose, ranging from 10 to 30 Gy, was administered in a fractionated manner (3-5 Gy/day, 5 days/week). Results: Perioperative fractionated IMBT was performed in 15 out of 18 patients and was well tolerated. Complications that partially prevented or delayed IMBT in some cases included cerebrospinal fluid leakage (twice), meningitis (twice), frontal brain syndrome (twice), afterloading tube displacement (twice), seizure (once), and general morbidity (once). No surgery- or radiation-induced injuries to the cranial nerves or eyes occurred. Median survival times were 33 months after diagnosis and 16 months after combined operation and IMBT. Conclusion: Perioperative fractionated IMBT after extensive but vision-preserving tumor resection seems to be a safe and well-tolerated treatment of advanced/recurrent malignancies involving the skull base. These preliminary state suggest that combined operation and perioperative fractionated IMBT is a palliative therapeutic option in the management of fatal malignancies involving the base of the skull, a strategy which leaves the patients' visual acuity intact.

    Full Text Available The objective of this exploratory, open-label, single-arm, phase II clinical trial was to evaluate plitidepsin (5 mg/m2 administered as a 3-hour continuous intravenous infusion every two weeks to patients with locally advanced/metastatic transitional cell carcinoma of the urothelium who relapsed/progressed after first-line chemotherapy. Treatment cycles were repeated for up to 12 cycles or until disease progression, unacceptable toxicity, patient refusal or treatment delay for >2 weeks. The primary efficacy endpoint was objective response rate according to RECIST. Secondary endpoints were the rate of SD lasting ≥6 months and time-to-event variables. Toxicity was assessed using NCI-CTC v. 3.0. Twenty-one patients received 57 treatment cycles. No objective tumor responses occurred. SD lasting <6 months was observed in two of 18 evaluable patients. With a median follow-up of 4.6 months, the median PFR and the median OS were 1.4 months and 2.3 months, respectively. The most common AEs were mild to moderate nausea, fatigue, myalgia and anorexia. Anemia, lymphopenia, and increases in transaminases, alkaline phosphatase and creatinine were the most frequent laboratory abnormalities. No severe neutropenia occurred. Treatment was feasible and generally well tolerated in this patient population; however the lack of antitumor activity precludes further studies of plitidepsin in this setting.

    Full Text Available Abstract Treatment of non-small-cell lung cancer is dependent on disease stage. For patients with metastasis or locally advanced disease, the importance of finding therapeutic schemes that may benefit this population is important. This review discusses therapeutic options for first- and second-line treatment in patients with advanced non-small-cell lung cancer. According to current data, the combination of two cytotoxic agents is the optimum first-line treatment for patients with non-small-cell lung cancer and performance status of 0–1. Addition of bevacizumab has shown to provide an even longer survival and to increase response rate. Within the first-line setting, erlotinib appears to be effective in the treatment of elderly patients who would not derive a benefit from standard chemotherapy or those refusing standard chemotherapy. The administration of erlotinib as first-line maintenance therapy is being assessed. There are currently three drugs approved for second-line treatment of patients with advanced non-small-cell lung cancer after failure of first-line chemotherapy. These drugs have proven to be effective in phase III trials. In the phase III trial BR.21 study, the response rate was 8.9% in the erlonitib group, and less than 1% in placebo; median response duration was 7.9 months and 3.7 months, respectively; and the median survival was 6.7 months and 4.7 with erlotinib and placebo, respectively. One-year survival was 31% and 21% with erlotinib and placebo, respectively. In addition, the BR.21 trial revealed that significantly greater improvements in overall quality of life and in both physical and emotional functioning were observed in the erlotinib arm as compared with the placebo arm. Erlotinib is not significantly associated with hematologic adverse effects. Erlotinib is administered orally, and does not require concomitant administration of other drugs, thus causing patients less inconvenience. Analysis of data from different

    A recent study concluded that serum prostate specific antigen (PSA)-based screening is beneficial for reducing the lethality of PCa, but was also associated with a high risk of 'overdiagnosis'. Nevertheless, also PCa patients who suffered from organ confined tumors and had negative bone scans succumb to distant metastases after complete tumor resection. It is reasonable to assume that those tumors spread to other organs long before the overt manifestation of metastases. Our current results confirm that prostate tumors are highly heterogeneous. Even a small subpopulation of cells bearing BRCA1 losses can initiate PCa cell regional and distant dissemination indicating those patients which might be at high risk of metastasis. A preliminary study performed on a small cohort of multifocal prostate cancer (PCa) detected BRCA1 allelic imbalances (AI) among circulating tumor cells (CTCs). The present analysis was aimed to elucidate the biological and clinical role of BRCA1 losses on metastatic spread and tumor progression in prostate cancer patients. Experimental Design: To map molecular progression in PCa outgrowth we used FISH analysis of tissue microarrays (TMA), lymph node sections and CTC from peripheral blood. We found that 14% of 133 tested patients carried monoallelic BRCA1 loss in at least one tumor focus. Extended molecular analysis of chr17q revealed that this aberration was often a part of larger cytogenetic rearrangement involving chr17q21 accompanied by AI of the tumor suppressor gene PTEN and lack of the BRCA1 promoter methylation. The BRCA1 losses correlated with advanced T stage (p < 0.05), invasion to pelvic lymph nodes (LN, p < 0.05) as well as BR (p < 0.01). Their prevalence was twice as high within 62 LN metastases (LNMs) as in primary tumors (27%, p < 0.01). The analysis of 11 matched primary PCa-LNM pairs confirmed the suspected transmission of genetic abnormalities between those two sites. In 4 of 7 patients with metastatic disease, BRCA1

  3. Outcomes in a Multi-institutional Cohort of Patients Treated With Intraoperative Radiation Therapy for Advanced or Recurrent Renal Cell Carcinoma

    International Nuclear Information System (INIS)

    Purpose/Objective(s): This study aimed to analyze outcomes in a multi-institutional cohort of patients with advanced or recurrent renal cell carcinoma (RCC) who were treated with intraoperative radiation therapy (IORT). Methods and Materials: Between 1985 and 2010, 98 patients received IORT for advanced or locally recurrent RCC at 9 institutions. The median follow-up time for surviving patients was 3.5 years. Overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were estimated with the Kaplan-Meier method. Chained imputation accounted for missing data, and multivariate Cox hazards regression tested significance. Results: IORT was delivered during nephrectomy for advanced disease (28%) or during resection of locally recurrent RCC in the renal fossa (72%). Sixty-nine percent of the patients were male, and the median age was 58 years. At the time of primary resection, the T stages were as follows: 17% T1, 12% T2, 55% T3, and 16% T4. Eighty-seven percent of the patients had a visibly complete resection of tumor. Preoperative or postoperative external beam radiation therapy was administered to 27% and 35% of patients, respectively. The 5-year OS was 37% for advanced disease and 55% for locally recurrent disease. The respective 5-year DSS was 41% and 60%. The respective 5-year DFS was 39% and 52%. Initial nodal involvement (hazard ratio [HR] 2.9-3.6, P<.01), presence of sarcomatoid features (HR 3.7-6.9, P<.05), and higher IORT dose (HR 1.3, P<.001) were statistically significantly associated with decreased survival. Adjuvant systemic therapy was associated with decreased DSS (HR 2.4, P=.03). For locally recurrent tumors, positive margin status (HR 2.6, P=.01) was associated with decreased OS. Conclusions: We report the largest known cohort of patients with RCC managed by IORT and have identified several factors associated with survival. The outcomes for patients receiving IORT in the setting of local recurrence compare favorably to

The patients were stratified into three groups: young (aged <45 years, middle-aged (aged 45–64 years, and old (aged ≥65 years. Overall survival (OS and progression-free survival (PFS curves were drawn using the Kaplan–Meier method, and Cox's proportional hazard regression model was used to compare OS and PFS within age groups. Results: There were no significant differences among young, middle-aged, and old groups in terms of OS (P=0.087, whereas PFS in the old group was significantly better than in the young and middle-aged groups (P=0.043.

    The majority of patients with pancreatic cancer is of advanced disease. Several randomized Phase II and III trials suggest that the combination of gemcitabine and cisplatin (GemCis) response rates were higher than Gemcitabine (Gem) alone, however the trials were not enough powered to indicate a statistically significant prolongation of survival in patients with advanced pancreatic adenocarcinoma. The aim of this retrospective multicenter study is to evaluated the efficiency of Gem alone versus GemCis in patients with locally advanced and/or metastatic pancreatic adenocarcinoma .A total of 406 patients, from fourteen centers were evaluated retrospectively. All patients received Gem or GemCis as first-line treatment between September 2005 to March 2011. Primary end of this study were to evaluate the toxicity, clinical response rate, progression-free survival (PFS) and overall survival (OS) between the arms. There were 156 patients (M: 98, F: 58) in Gem arm and 250 patients (M: 175, F: 75) in the combination arm. Gemcitabin arm patients older than the combination arm ( median 63 vs 57.5, p=0.001). In patients with the combination arm had a higher dose reduction (25.2% vs 11.3%, p=0.001) and dose delay (34% vs 16.8%, p=0.001). Among patients with the combination and Gemcitabin arm gender, diabetes mellitus, performance status, cholestasis, grade, stage did not have a statistically difference (p>0.05). Clinical response rate to the combination arm was higher than the Gem arm (69.0% vs 49.7%, p=0.001). PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance (8.9 vs 6.0, p=0.08). OS was not significantly superior in the GemCis arm (12.0 vs 10.2, p>0.05). Grade III-IV hematologic and nonhematologic toxicity were higher in the combination arm. PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance. OS was not significantly superior in the GemCis arm.

    Chordomas are rare malignant bone tumours with a predilection for the axial skeleton, especially the sacrum and skull base. Median survival in patients with metastatic disease is usually dismal. Treatment is challenging due to the propensity for local recurrence, metastatic disease as well as lack of clear consensus regarding the optimal management. Our case report highlights two cases of sacral chordoma with locally recurrent and widespread metastatic disease, stable on molecular targeted therapy. PMID:26180502

    Conclusion: Forequarter amputation can be judiciously used for patients with recurrent or metastatic breast cancer. Patients with recurrent disease without evidence of distant metastases may be considered for curative amputation, while others may receive palliative benefit; disappointingly our patient achieved neither of these outcomes. In the long term, these patients may still have significant psychological problems.

    Background The combined therapy of bevacizumab (BEV) with taxane (paclitaxel or docetaxel) has shown an improvement on progression-free survival (PFS) and objective remission in Her2-negative patients with locally recurrent or metastatic breast cancer (LR/MBC). However, there was no benefit in overall survival (OS). The aim of this study was to evaluate the efficacy and safety of adding an agent to the BEV/taxane regimens for the treatment of Her2-negative patients with LR/MBC in a first-line setting. Materials and methods We searched PubMed, Web of Science, EMBASE, EBSCO, and the Cochrane Library databases for eligible trials. A meta-analysis was performed using Review Manager 5.0 freeware package. We calculated the hazard ratio (HR) for PFS and OS. The odds ratio (OR) was used to calculate objective response rate (ORR) and grade 3/4 drug-related adverse events. The heterogeneity of study outcomes was calculated by the χ2 test or I2 statistics. Results A total of 1,124 patients from seven randomized controlled trials were analyzed. Our meta-analysis showed that the ORR was significantly improved in the BEV/taxane-based triplet group when compared with the BEV/taxane-based doublet group (OR =1.31, 95% confidence interval [CI]: 1.03–1.67, P=0.03). A subset analysis showed that a similar result was achieved in the triplet group in which a cytotoxic agent was added (OR =1.46, 95% CI: 1.09–1.95, P=0.01). However, the PFS and OS had no statistically significant differences between the two groups (HR =0.87, 95% CI: 0.68–1.13, P=0.31; HR =0.98, 95% CI: 0.82–1.16, P=0.78, respectively). Regarding safety, thromboembolic events, fatigue, and diarrhea (all $grade 3) were more frequently observed in the BEV/taxane-based triplet group (OR =3.8, 95% CI: 1.86–7.79, P=0.0003; OR =1.55, 95% CI: 1.05–2.27, P=0.03; OR =2.1, 95% CI: 1.29–3.41, P=0.003, respectively). Other toxic effects had no statistically significant differences between the two groups. Conclusion Our

    Full Text Available The accurate identification of glioblastoma progression remains an unmet clinical need. The aim of this prospective single-institutional study is to determine and validate thresholds for the main metabolite concentrations obtained by MR spectroscopy (MRS and the values of the apparent diffusion coefficient (ADC to enable distinguishing tumor recurrence from pseudoprogression. Thirty-nine patients after the standard treatment of a glioblastoma underwent advanced imaging by MRS and ADC at the time of suspected recurrence — median time to progression was 6.7 months. The highest significant sensitivity and specificity to call the glioblastoma recurrence was observed for the total choline (tCho to total N-acetylaspartate (tNAA concentration ratio with the threshold ≥1.3 (sensitivity 100.0% and specificity 94.7%. The ADCmean value higher than 1313 × 10−6 mm2/s was associated with the pseudoprogression (sensitivity 98.3%, specificity 100.0%. The combination of MRS focused on the tCho/tNAA concentration ratio and the ADCmean value represents imaging methods applicable to early non-invasive differentiation between a glioblastoma recurrence and a pseudoprogression. However, the institutional definition and validation of thresholds for differential diagnostics is needed for the elimination of setup errors before implementation of these multimodal imaging techniques into clinical practice, as well as into clinical trials.

    Full Text Available Metastatic Lymphadenopathy is a common occurrence now with the earlier detection possible due to advances in imaging sciences. Although, at times the site of original malignancy is known; there are instances when the primary source of malignancy remains unknown. Ultrasound has the potential to non invasively evaluate the affected lymph nodes. Hence we reviewed the ultrasound findings in all fine needle aspiration cytology proven cases of metastatic lymphadenopathy that presented in the imaging department in the last 12 months. Multiple criteria on Grey Scale ultrasound imaging and on Color Doppler ultrasound imaging were used to label metastatic lymphadenopathy. Round nodes without any matting, presence of intranodal necrosis, intranodal calcifications, increased vascularity and elevated Doppler Pulsatility and Resisitivity Indices were the hallmarks of metastatic lymphadenopathy which enabled correct diagnosis with a sensitivity of 85.25% and a sensitivity of 98.36 %. In our review, the most sensitive and specific criteria was the Roundness Index on Gray scale imaging and Resistance to Perfusion on Color Doppler imaging. This review shows how, ultrasound can satisfactorily diagnose metastatic lymphadenopathy and can therefore be used in the diagnosis as well as follow up of such cases.

    Full Text Available Ewing sarcoma (ES is the second most common bone tumor affecting primarily adolescents and young adults. Despite recent advances in biological understanding, intensification of chemotherapeutic treatments, and progress in local control with surgery and/or radiation therapy, patients with metastatic or recurrent ES continue to have a dismal prognosis with less than 20% overall survival. All ES likely is metastatic at diagnosis although our methods of detection and classification may not account for this. Progressive disease may arise via a combination of: 1 selection of chemotherapy-resistant clones, 2 signaling from bone or lung microenvironments that may attract tumor cells to distant locations, and/or 3 genetic changes within the ES cells themselves due to a combination of therapy-related selection and DNA-damaging chemotherapeutic agents. These possibilities and the evidence base to support them are explored.

    Cancer metastasis is considered as a complex process involving a series of sequential steps and a variety of molecalar signal transduction pathways.Tumor recurrence and metastasis are major obstacles for long-term survival of Liver cancer patients.Although the prognosis after recurrence and metastasis is dismal,the advancement of molecular researches of metastasis of liver cancer seems promising.In studies of origins of metastasis of liver cancer,the primary cancer cell and corresponding metastatic liver cancer cells share similar gene signature,which indicates that genes favoring metastasis progression are initiated in the primary tumors.The metastasis of liver cancer may be an early event in hepatic carcinogenesis and progression.Some molecular signatures have been developed to classify the metastatic potential of liver cancer.Furthermore,a variety of studies demonstrate that the tumor microenvironment instead of tumor cells plays a more important role in liver cancer metastasis.The pre-metastatic niche composed of non-tumoral cells may promote the cancer cell sedimentation and progression.The theory of cancer stem cell speculates that cancer stem cells were the real source of recurrent or metastatic tumors.Cancer stem cells will be one of the main targets of liver cancer treatment.The prevention and treatment of liver cancer recurrence or metastasis are quite difficult because liver cancer is resistant to traditional chemotherapy.Targeting the molecules involved in the metastasis of liver cancer WOuld be promising to cure those diseases.

    Full Text Available Context: There are limited effective therapeutic options in the relapsed setting for non-small cell lung cancer (NSCLC or in the first line for platinum-ineligible patients. Aim: To evaluate the safety and efficacy of a metronomic schedule of paclitaxel administered weekly in relapsed refractory NSCLC or upfront in patients not eligible for platinum-based chemotherapy. Settings and Design: Retrospective analysis of a prospectively collected database from the medical oncology department at Tata Memorial Hospital in Mumbai, India. Materials and Methods: Patients with recurrent and treatment-naïve platinum-ineligible advanced NSCLC were treated with weekly paclitaxel at 80 mg/m 2 with palliative intent. Restaging scans were obtained every two months. Chemotherapy was continued until progressive disease, intolerable side effects, or decision of the patient. Statistical Analysis Used: SPSS version 16 was used for analysis. Simple percentages were used for descriptive statistics. Progression-free survival (PFS was calculated from date of start of paclitaxel till the date of progression, change of therapy due to any reason, or death due to any cause. Overall survival (OS was calculated from date of start of paclitaxel to death. The Kaplan Meier method was used for estimation of survival. Results: There were 37 patients over eight months. The median age was 59 years, with a male-to-female ratio of 5:1. Two patients received paclitaxel in the first line, 18 patients in second line, nine in third line, five in fourth line, and three were in fifth line. 73% patients had received prior platinum and 48.6% patients had Eastern Cooperative Oncology Group performance status (ECOG PS >2. The median number of weekly cycles delivered was 14. The response rate was 35% [complete remission (CR: 2.7%, partial remission (PR: 32.4%, stable disease (SD: 32.4%, progressive disease (PD: 27%], the median PFS was four months, and the estimated median OS was seven months

    Metastatic human HCC model is needed for the studies on mechanism and intervention of metastatic recurrence. By using orthotopic implantation of histologically intact tissues of 30 surgical specimens, a patient like metastatic model of human HCC in nude mice (LCI-D20)and a Iow metastatic model of human HCC in nude mice LCI-D35 ) have been established. All mice with transplanted LCI-D20 tumors exhibited extremely high metastatic ability including spontaneous metastasis to liver, lungs, lymph nodes and peritoneal seeding.Remarkable difference was also found in expression of some of the invasiveness related genes and growth factors between the LCI-D20 and LCI-D35 tumors. PAI-Iincreased gradually following tumor progression in LCID20 model, and correlated with tumor size and AFP level,Phasic expression of tissue intercellular adhesion molecule-I in this model was also observed. Using corneal micropocket model, it was demonstrated that the vascular response induced by LCI-D20 tumor was stronger than that induced by LCI-D35 tumor. Similar report on metastatic human HCC model in nude mice and human HCC cell line with metastatic potential was rarely found in the literature. This LCI-D20 model has been widely used for the studies on intervention of metastasis, including antiangiogenesis, antisense approach, metalloproteinase inhibitor, differentiation inducer, etc. It is concluded that the establishment of metastatic human HCC model in nude mice and human HCC cell line with metastatic potential will provide important models for the in vivo and in vitro study of HCC invasiveness, angiogenesis as well as intervention of HCC recurrence.``

    Full Text Available We are reporting on a case of a 41-year-old woman who presented with metastatic gastroesophageal junction cancer and who achieved prolonged survival with a multimodal treatment approach. After initially experiencing robust response to chemotherapy, she was treated for distant recurrence with palliative radiation to the gastrohepatic and supraclavicular lymph nodes and subsequently, given her unusual near-complete response, with reirradiation to the abdomen with curative intent for residual disease. The case presented is unique due to the patient’s atypical treatment course, including technically difficult reirradiation to the abdomen, and the resulting prolonged survival despite metastatic presentation.

    The National Institute for Health and Clinical Excellence (NICE) invited the manufacturer of pazopanib hydrochloride (GlaxoSmithKline) to submit evidence of the clinical and cost effectiveness of the drug for the first-line treatment of advanced and/or metastatic renal cell carcinoma, as part of the Institute's single technology appraisal (STA) process. The Aberdeen Health Technology Assessment Group were commissioned to act as the Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and NICE's subsequent decisions. The objective of this paper is to summarize the independent review and critique of the evidence submitted for the consideration of the NICE Appraisal Committee and NICE's subsequently issued guidance. The ERG produced a critical review of the evidence for the clinical and cost effectiveness of the technology based upon the manufacturer's submission to NICE. The ERG also independently searched for relevant evidence and modified the manufacturer's decision analytic model to examine the impact of altering some of the key assumptions. For progression-free survival (PFS), there was a statistically significant longer survival for pazopanib compared with placebo (as assessed by the ERG, based upon the original manufacturer submission with a clinical cut-off date of 23 May 2008) [median 11.1 vs. 2.8 months; hazard ratio (HR) 0.40; 95 % CI 0.27, 0.60]. Data from the indirect comparison suggested that pazopanib had a greater survival than interferon alpha (IFN-α) [HR 0.512; 95 % CI 0.326, 0.802] but provided no evidence of any difference compared with sunitinib (HR 0.949; 95 % CI 0.575, 1.568). With regard to overall survival, 64 % (n = 99) of patients in the pazopanib arm and 63 % (n = 49) of patients in the placebo arm had died and a total of 51 % (n = 40) of placebo patients had crossed over to receive pazopanib. Although data were provided on an intention-to-treat basis, crossover between therapies

  8. A phase I study on combined therapy with proton-beam radiotherapy and in situ tumor vaccination for locally advanced recurrent hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Proton-beam radiotherapy (PBT) has been shown to be effective to hepatocellular carcinoma (HCC) as a nonsurgical local treatment option. However, HCC still remains as one of the most difficult cancers to be cured because of frequent recurrences. Thus, methods to inhibit the recurrence need to be explored. To prevent the HCC recurrence, we here report on a prospective phase I study of ‘in situ’ tumor vaccination using CalTUMP, a newly developed immunoadjuvant consisting of BCG extract bound to hydroxyapatite and microparticulated tuberculin, following local PBT for HCC. Patients with locally advanced recurrent HCC, which had been heavily pretreated with various treatments, were enrolled. PBT was performed with the conventional method to the target HCC. Subsequently, CalTUMP was injected into the same irradiated-tumor three times at one-week intervals. Three dose-levels of CalTUMP (1/10, 1/3, and 1/1) were administered to 3 patients each. Vital signs, blood samples, ultrasound, and computed tomographic scans were monitored to evaluate the safety. Three intratumoral injections of CalTUMP following PBT (median dose: 72.6 GyE) were accomplished in 9 patients. Transient low-grade fever and minor laboratory changes were observed in 7 patients after CalTUMP injections. No other treatment-related adverse events were observed. Median progression-free survival was 6.0 months (range: 2.1-14.2) and 4 patients were progression-free for more than 1 year. Intratumoral injection of CalTUMP following PBT was feasible and safe in patients with heavily pre-treated HCC. Further clinical studies to evaluate the efficacy of this in situ tumor vaccination are warranted

    117 women with severe pelvic organ prolapse (POP; stage > 2) were enrolled to elucidate a 24-month outcome of POP surgery, using conventional or mesh repair with 3 techniques. 59 patients underwent conventional repair and 58 underwent mesh repair. Two types of mesh were used: a trocar-guided transobturator polypropylene (Avaulta, Bard Inc.) and a porcine dermis mesh (Pelvisoft, Bard Inc.). Women with recurrences, who underwent previous unsuccessful conventional repair, were randomised. Primary outcome was the evaluation of anatomic failures (prolapse stage > 1) in treated and untreated compartments. Anatomic failure was observed in 11 of 58 patients (19%; CI 8.9-29) in the mesh group and in 16 of 59 patients (27.1%; p value = 0.3) in the conventional group. 9 of 11 failures in the mesh group (15.5%; CI 6.2-24.8) were observed in the untreated compartment (de novo recurrences), 14.3% in Pelvisoft and 16.7% in Avaulta arm, while only 1 recurrence in the untreated compartment (1.7%) was observed in the conventional group (odds ratio 10.6, p = 0.03).

    随着对胃肠间质瘤(GIST)认识的提高,临床上诊断为GIST患者的比例逐年升高.早期GIST行手术完整切除预后良好,而进展期GIST无论是在单纯手术治疗阶段、单纯伊马替尼靶向治疗阶段还是手术联合伊马替尼治疗阶段,手术后再复发、伊马替尼耐药和靶向药物多重耐药等问题仍然是目前治疗的难点.大量的临床证据显示,合理的治疗策略可以改善进展期GIST患者的预后.进展期GIST绝不能单纯认为是内科或者外科疾病,需要包括肿瘤外科、肿瘤内科、病理科、影像科和介入科等多学科协作组的综合诊疗.本文结合目前国内外最新研究进展,基于循证医学证据和笔者经验,提出进展期GIST的合理诊疗策略,以期达到早期发现、初期预防和恰当管理的目标,从而改善患者预后,延长生存期.%With deeper understanding of gastrointestinal stromal tumor (GIST),more and more patients are diagnosed as GIST.Although the prognosis of early GIST is satisfactory after complete surgical resection, there are still many problems in the treatment of advanced GIST. Variety of treatment options has been used in the treatment of GIST,such as surgery, targeted drug therapy, and surgery plus imatinib therapy. However, post-operative recurrence,imatinib-resistance, multi-targeted drug resistance are still challenges.Many clinical evidences show that a reasonable management strategy can improve the prognosis of patients with advanced GIST.All the doctors should have a clear mind to carry out appropriate interventions.Advanced GIST should not be simply considered to be either medical or surgical disease, but rather must be systemetically managed by multidisciplinary team approach combining surgical oncology,medical oncology, pathology, and interventional medicine.This review will advocate suitable treatment strategies based on the most recent progresses in systemic treatment for advanced GIST and our clinical

  13. A comparative study between the effectiveness of chemoendocrine therapy and chemoendocrine therapy combined with radiation for the treatment of advanced and/or recurrent breast cancers

    International Nuclear Information System (INIS)

    The members of the Surgical and Radiation Oncology Group for Breast Cancers have conducted a controlled trial to evaluate the effectiveness of chemoendocrine therapy alone or combined with radiotherapy for advanced and/or recurrent breast cancers. The subjects were divided into two groups, based on the therapeutic regimen: Group A, 18 lesions, received an alternating TAM/MPA plus 5-FU chemotherapy, and Group B, 15 lesions, received this same chemoendocrine therapy combined with radiation (45 to 60 Gy for 4 to 6 weeks). In Group A, 4 out of 18 lesions (22.2%) responsed to the treatment, whereas in Group B, 10 out of 15 (66.7%) responded to the treatment (p=0.0265). Further, in Group A, only 2 lesions (11.1%) achieved a complete remission (CR), whereas in Group B, 9 lesions (60%) achieved a CR (p=0.0094). The incidence of leukopenia, however, was higher in Group B, but this did not affect the continuance of therapy. It was thus concluded that the combined therapy was more effective and contributed to the improvement of a greater number of the advanced and/or recurrent breast cancer cases. (author)

    Cystic meningioma is a rare form of intracranial meningioma. Meningiomas are typically solid tumors but may rarely have cystic components. The diagnosis of cystic meningioma is clinically challenging as the finding of multiple intra-axial tumors, including metastatic tumors, is relatively common.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    2009-06-01

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Full Text Available Abstract Background The incidence of thyroid cancer and the number of patients who die from this disease are increasing globally. Differentiated thyroid cancer (DTC is the histologic subtype present in most patients and is primarily responsible for the increased overall incidence of thyroid cancer. Sorafenib is a multikinase inhibitor that targets several molecular signals believed to be involved in the pathogenesis of thyroid cancer, including those implicated in DTC. In phase II studies of patients with DTC, sorafenib treatment has yielded a median progression-free survival (PFS of 58 to 84 weeks and disease control rates of 59% to 100%. The DECISION trial was designed to assess the ability of sorafenib to improve PFS in patients with locally advanced or metastatic, radioactive iodine (RAI-refractory DTC. Methods/design DECISION is a multicenter, double-blind, randomized, placebo-controlled phase III study in patients with locally advanced/metastatic RAI-refractory DTC. Study treatment will continue until radiographically documented disease progression, unacceptable toxicity, noncompliance, or withdrawal of consent. Efficacy will be evaluated every 56 days (2 cycles, whereas safety will be evaluated every 28 days (1 cycle for the first 8 months and every 56 days thereafter. Following disease progression, patients may continue or start sorafenib, depending on whether they were randomized to receive sorafenib or placebo, at investigator discretion. Patients originally randomized to receive sorafenib will be followed up every 3 months for overall survival (OS; patients originally randomized to receive placebo will be followed up every month for 8 months after cross-over to sorafenib. The duration of the trial is expected to be 30 months from the time the first patient is randomized until the planned number of PFS events is attained. The primary endpoint is PFS; secondary endpoints include OS, time to disease progression, disease control rate

    2010-01-01

    Full Text Available The treatment of metastatic prostate cancer patients refractory to androgen withdrawal and docetaxel therapy is currently discouraging and new therapeutic approaches are vastly needed. Here, we report a long-term remission over one year in a 68-year-old patient with metastatic docetaxel-refractory prostate cancer employing low-dose trofosfamide. The patient suffered from distant failure with several bone lesions and lymph node metastases depicted by a (11 C-Choline positron emission tomography/computerized tomography (PET/CT. After initiation of trofosfamide 100 mg taken orally once a day we observed a steadily decreasing PSA value from initial 46.6 down to 2.1 g/l. The Choline-PET/CT was repeated after 10 months of continuous therapy and demonstrated a partial remission of the bone lesions and a regression of all involved lymph nodes but one. Taken together we found an astonishing and durable activity of the alkylating agent trofosfamide given in a metronomic fashion. We rate the side effects as low and state an excellent therapeutic ratio of this drug in our patient.

    Hepatocellular carcinoma (HCC) is an aggressive liver tumor that occurs with chronic liver disease. Surgical resection is the mainstay of therapy for localized disease whereas therapeutic options for advanced disease are limited. The innovative blockade of immune checkpoints with targeted immunotherapies, such as monoclonal antibodies against programmed death receptor 1 (PD-1), have shown promise in the treatment of solid malignancies. The PD-1 inhibiting antibodies, nivolumab and pembrolizumab prolonged overall survival in randomized trials in metastatic melanoma and advanced non-small cell lung cancer. This is a report of a 75-year-old male patient with metastatic HCC who was initially treated with the standard of therapy sorafenib. After failure of sorafenib therapy, pembrolizumab was started. There was a dramatic response to pembrolizumab with decrease in tumor size and drop in alfa fetoprotein. To the best of our knowledge, this is the first case report of metastatic HCC responsive to pembrolizumab after failure of sorafenib.

    BACKGROUND Polo-like kinases (Plks) control multiple steps during the cell cycle, and Plk1 is overexpressed in urothelial cancer (UC). Volasertib (BI 6727), a Plk inhibitor, has demonstrated antitumor activity in several malignancies, including UC. In this phase 2 trial, the authors investigated volasertib as a second-line treatment in advanced/metastatic UC. METHODS Patients who progressed within 2 years of 1 prior chemotherapy regimen received 300 mg volasertib on day 1 every 3 weeks. The dose was escalated to 350 mg in cycle 2 if volasertib was tolerated in cycle 1. The primary endpoint was tumor response, which was assessed every 6 weeks; secondary endpoints were progression-free survival, overall survival, duration of response, safety, and pharmacokinetics. RESULTS Fifty patients were enrolled, and the median patient age was 68.5 years (range, 52-83 years). All patients had received prior platinum, 94% of patients had relapsed ≤2 years after prior therapy, 36% had liver metastases, and 54% had lung metastases. The median number of treatment cycles was 2 (range, 1-27 treatment cycles), and 23 patients were dose escalated at cycle 2. Seven patients (14%) had a partial response, 13 (26%) had stable disease, and 30 (60%) progressed within 6 weeks. The median response duration was 41 weeks (range, 29.1-77.3 weeks). The median progression-free survival was 1.4 months, and the median overall survival was 8.5 months. The most frequent grade 3 and 4 adverse events were neutropenia (28%), thrombocytopenia (20%), and anemia (16%). No cumulative toxicity was observed. CONCLUSIONS Volasertib as second-line treatment for advanced/metastatic UC had an acceptable safety profile but demonstrated insufficient antitumor activity for further evaluation as a monotherapy.

    Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25%) were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19-167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis), decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted.

  14. A pilot study of preoperative continuous infusion 5-fluorouracil, external microwave hyperthermia, and external beam radiotherapy for treatment of locally advanced, unresectable, or recurrent rectal cancer

    International Nuclear Information System (INIS)

    Purpose: To determine the feasibility of combining external beam radiotherapy, continuous infusion 5-fluorouracil (5-FU), and external microwave hyperthermia in patients with locally advanced, unresectable, or recurrent adenocarcinoma of the rectum. Methods and Materials: From 7/95 through 2/99, 15 patients were enrolled in the study. The treatment regimen consisted of continuous infusion 5-FU 250 mg/m2/d 7 days/week beginning on day 1, external beam radiotherapy to the pelvis, 4500 cGy, 180 cGy/d 5 days/week using a 3 or 4-field technique, and external microwave hyperthermia on days 3, 8, 15, 22, and 29. Chemotherapy was stopped on the last day of radiotherapy. Surgical resection, if feasible, was scheduled 3-6 weeks after completing thermochemoradiotherapy. For this regimen to be considered feasible, no more than 2 of the 15 patients should fail to complete therapy due to life-threatening toxicity. Toxicity was scored using National Cancer Institute Criteria. Results: All patients completed the chemoradiotherapy portion of the protocol. Eleven of the 15 patients completed all 5 hyperthermia treatments. Of the 4 patients who did not receive the full course of hyperthermia, only 1 patient had treatment stopped due to life-threatening toxicity. The other 3 patients did not complete hyperthermia due to scheduling errors (n = 2) or patient request (n = 1). Five of 15 patients required a treatment interruption due to toxicity no. >=no. Grade 3. Seven patients experienced lesser degrees of toxicity which did not require treatment interruption. Three patients experienced no side effects. The most common toxicities were dermatitis and diarrhea. Of the 14 patients in whom surgery was planned, 11 (79%) were resectable. There was one pathologic complete response. Conclusions: It is feasible to deliver thermochemoradiotherapy, as prescribed in this study, to patients with locally advanced, unresectable, or recurrent rectal cancer. The therapy is moderately toxic, with one

    Vulvovaginitis (VV) is one of the most commonly encountered problems by a gynecologist. Many women frequently self-treat with over-the-counter medications, and may present to their health-care provider after a treatment failure. Vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis may occur as discreet or recurrent episodes, and have been associated with significant treatment cost and morbidity. We present an update on diagnostic capabilities and treatment modalities that address recurrent and refractory episodes of VV. PMID:25220102

    2012-01-01

    On 13 July 2011 the European Commission issued a marketing authorisation valid throughout the European Union (EU) for ipilimumab for the treatment of advanced (unresectable or metastatic) melanoma in adults who have received prior therapy. Ipilimumab is a monoclonal antibody that specifically blocks the inhibitory signal of cytotoxic T lymphocyte antigen 4 (CTLA-4), resulting in T cell activation, proliferation and lymphocyte infiltration into tumours, leading to tumour cell death. The recommended induction regimen of ipilimumab is 3mg/kg administered intravenously over a 90 min period every 3 weeks for a total of four doses. In a phase 3 trial in patients with advanced melanoma, median overall survival for ipilimumab was 10 months versus 6 months for gp100, an experimental melanoma vaccine (Hazard ratio (HR) 0.66; 95% confidence interval (CI): 0.51, 0.87; p = 0.0026). Ipilimumab was most commonly associated with adverse reactions resulting from increased or excessive immune activity. Most of these, including severe reactions, resolved following initiation of appropriate medical therapy or withdrawal of ipilimumab. The most common side-effects (affecting more than 10% of patients) were diarrhoea, rash, pruritus, fatigue, nausea, vomiting, decreased appetite and abdominal pain. The objective of this paper is to summarise the scientific review of the application leading to approval in the EU. The detailed scientific assessment report and product information, including the summary of product characteristics (SmPC), are available on the European Medicines Agency (EMA) website (www.ema.europa.eu).

  17. Management of metastatic apocrine hidradenocarcinoma with chemotherapy and radiation

    Directory of Open Access Journals (Sweden)

    Daniel H. Miller

    2015-10-01

    Full Text Available Hidradenocarcinoma is a rare aggressive form of cutaneous adnexal skin carcinoma originating from the sweat gland. Due to its low incidence, prognostic and treatment strategies are still being explored both for primary and advanced disease. This tumor most often presents as either solid or cystic appearing subcutaneous nodules, which may be associated with pruritus or ulceration. To date the mainstay of treatment for local disease has been surgical excision; however, the paucity of historical data available has shown that these tumors often behave aggressively with high rates of local recurrence, metastasis, and poor overall outcomes. There are few case reports describing the utility of radiation therapy in the treatment of hidradenocarcinoma. Herein, we present a case of metastatic apocrine hidradenocarcinoma in a 32-year-old Caucasian male. The patient initially underwent excisional biopsy which confirmed the diagnosis of poorly differentiated, highly infiltrative, apocrine hidradenocarcinoma. He received systemic chemotherapy for metastatic disease, followed by radiation therapy to areas of grossly palpable adenopathy. Prior to radiation therapy the patient had an enlarged hypermetabolic conglomerate of lymph nodes in the right axilla, and borderline enlarged low activity nodes within the left axilla. He received 3 cycles of chemotherapy followed by tamoxifen and radiation therapy (50.4 Gy in 28 fractions to areas of progressive disease in the bilateral axilla, lower neck, and axillary skin. Following treatment, the patient had complete resolution of skin nodules and improvement of his pruritus. While the role of radiation therapy in the treatment of hidradenocarcinoma has not been well established, this case report demonstrated the potential benefit of external beam radiotherapy in the management of this rare disease

    2011-01-01

    Full Text Available Medullary thyroid carcinoma accounts for 4% of thyroid carcinoma and originates from parafollicular cells, secreting calcitonin and carcinoembryonic antigen (CEA. Conventional radiographic modalities such as Computerized Tomography (CT, Magnetic Resonance Imaging (MRI, and Ultrasonography (U/S, are used for detecting recurrences following total thyroidectomy. However, metastatic disease frequently escapes detection by the above modalities, even when its presence is suggested by persistently elevated serum calcitonin levels. In this paper, we report a case of medullary thyroid carcinoma in a 40 year-old woman who had whole body octreotide scintigraphy to evaluate and detect the origin of calcitonin and CEA secretion.

    目的 探讨混合调强放疗在局部晚期和晚期肺癌放射治疗中的剂量学特点.方法 对16例不适合做适形放疗的肺癌患者分别设计单纯调强计划和混合调强计划,比较两种计划的剂量学差异.结果 两种计划均满足临床要求,而混合调强计划的靶区适形度(CI)和均匀性(HI)均优于调强计划(P<0.05).混合调强计划中全肺受照5、10、13、15和20 Gy剂量的体积V5、V10、V13、V15、V20和平均剂量(MLD)均明显小于调强计划(P<0.05).结论 混合调强明显减少了与放射性肺炎发生率相关的中低剂量照射体积,降低了脏器运动引起的剂量误差,减小了剂量计算误差,对局部晚期和晚期肺癌的放疗有一定的剂量学优势.%[ Objective ]To explore the dosimetric characteristics of hybrid intensity-modulated radiation therapy (IMRT) for locoregionally and metastatically advanced lung cancer.[Methods]Both full IMRT plan and hybrid IMRT plan were designed in each of 16 lung cancer patients who were unsuitable for three-dimensional conformal radiation therapy.The dosimetric differences of the two techniques were compared. [ Results ]Both the conformity index (CI) and the heterogeneity index (HI) of hybrid IMRT plan were superior to full IMRT plan,though both plans met the clinical requirements (P <0.05).The total irradiated lung volume by 5,10,13,15 or 20 Gy and the mean lung dose (MLD) were significantly reduced when hybrid IMRT plan rather than full IMRT was applied (P <0.05).[ Conclusion ]Hybrid IMRT can reduce the irradiated lung volumes under low and intermediate dose which is associated with the radiation pneumonitis.Moreover,the dose deviations due to organ motion and calculation are reduced.Therefore,hybrid IMRT has advantages in radiotherapy dosimetry for locoregionally and metastatically advanced lung cancer.

    3'-Deoxy-3'-{sup 18}F-fluorothymidine (FLT) positron emission tomography (PET) has limited utility in abdominal imaging due to high physiological hepatic uptake of tracer. We evaluated FLT PET/CT combined with a temporal-intensity information-based voxel-clustering approach termed kinetic spatial filtering (FLT PET/CT{sub KSF}) for early prediction of response and survival outcomes in locally advanced and metastatic pancreatic cancer patients receiving gemcitabine-based chemotherapy. Dynamic FLT PET/CT data were collected before and 3 weeks after the first cycle of chemotherapy. Changes in tumour FLT PET/CT variables were determined. The primary end point was RECIST 1.1 response on contrast-enhanced CT after 3 months of therapy. Twenty patients were included. Visual distinction between tumours and normal pancreas was seen in FLT PET{sub KSF} images. All target lesions (>2 cm), including all primary pancreatic tumours, were visualised. Of the 11 liver metastases, 3 (<2 cm) were not visible after kinetic filtering. Of the 20 patients, 7 progressed (35 %). Maximum standardised uptake value at 60 min post-injection (SUV{sub 60,max}) significantly increased in patients with disease progression (p = 0.04). Receiver-operating characteristic curve analysis indicated that a threshold of SUV{sub 60,max} increase of ≥ 12 % resulted in sensitivity, specificity and positive predictive value (PPV) of 71, 100 and 100 %, respectively [area under the curve (AUC) 0.90, p = 0.0001], to predict patients with disease progression. Changes in SUV{sub 60,max} were not predictive of survival. FLT PET/CT detected changes in proliferation, with early increase in SUV{sub 60,max} predicting progressive disease with a high specificity and PPV. Therefore, FLT PET/CT could be used as an early response biomarker for gemcitabine-based chemotherapy, to select a poor prognostic group who may benefit from novel therapeutic agents in advanced and metastatic pancreatic cancer.

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

    Full Text Available Abstract Survivin is a member of the inhibitor of apoptosis protein (IAP family containing a single baculovirus IAP repeat domain. It is expressed during fetal development but becomes undetectable in terminally differentiated normal adult tissues. We previously reported that survivin and its splicing variant survivin-2B was expressed abundantly in various types of tumor tissues as well as tumor cell lines and was suitable as a target antigen for active-specific anti-cancer immunization. Subsequently, we identified an HLA-A24-restricted antigenic peptide, survivin-2B80-88 (AYACNTSTL recognized by CD8+ cytotoxic T lymphocytes (CTLs. We, therefore, started a phase I clinical study assessing the efficacy of survivin-2B peptide vaccination in patients with advanced or recurrent colorectal cancer expressing survivin. Vaccinations with survivin-2B peptide were given subcutaneously six times at 14-day intervals. Of 15 patients who finished receiving the vaccination schedule, three suffered slight toxicities, including anemia (grade 2, general malaise (grade 1, and fever (grade 1. No severe adverse events were observed in any patient. In 6 patients, tumor marker levels (CEA and CA19-9 decreased transiently during the period of vaccination. Slight reduction of the tumor volume was observed in one patient, which was considered a minor responder. No changes were noted in three patients while the remaining eleven patients experienced tumor progression. Analysis of peripheral blood lymphocytes of one patient using HLA-A24/peptide tetramers revealed an increase in peptide-specific CTL frequency from 0.09% to 0.35% of CD8+ T cells after 4 vaccinations. This phase I clinical study indicates that survivin-2B peptide-based vaccination is safe and should be further considered for potential immune and clinical efficacy in HLA-A24-expression patients with colorectal cancer.

  8. The technical feasibility of an image-guided intensity-modulated radiotherapy (IG-IMRT) to perform a hypofractionated schedule in terms of toxicity and local control for patients with locally advanced or recurrent pancreatic cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the technical feasibility of an image-guided intensity modulated radiotherapy (IG-IMRT) using involved-field technique to perform a hypofractionated schedule for patients with locally advanced or recurrent pancreatic cancer. From May 2009 to November 2011, 12 patients with locally advanced or locally recurrent pancreatic cancer received hypofractionated CCRT using TomoTherapy Hi-Art with concurrent and sequential chemotherapy at Seoul St. Mary’s Hospital, the Catholic University of Korea. The total dose delivered was 45 Gy in 15 fractions or 50 Gy in 20 fractions. The target volume did not include the uninvolved regional lymph nodes. Treatment planning and delivery were performed using the IG-IMRT technique. The follow-up duration was a median of 31.1 months (range: 5.7-36.3 months). Grade 2 or worse acute toxicities developed in 7 patients (58%). Grade 3 or worse gastrointestinal and hematologic toxicity occurred in 0% and 17% of patients, respectively. In the response evaluation, the rates of partial response and stable disease were 58% and 42%, respectively. The rate of local failure was 8% and no regional failure was observed. Distant failure was the main cause of treatment failure. The progression-free survival and overall survival durations were 7.6 and 12.1 months, respectively. The involved-field technique and IG-IMRT delivered via a hypofractionated schedule are feasible for patients with locally advanced or recurrent pancreatic cancer

    Urothelial cancer is a common malignancy. The management of patients with recurrent disease after cystectomy or initially metastatic or unresectable disease represents a therapeutic challenge. Systemic chemotherapy prolongs survival but long-term survival remains infrequent. During recent years there has been improvement due to the use of novel chemotherapeutic agents, mainly gemcitabine and the taxanes. The long-considered-standard MVAC has been challenged by combinations showing more favourable toxicity profiles and equal (gemcitabine-cisplatin) or even improved (dose-dense, G-CSF-supported MVAC) efficacy. Specific interest has also been generated in specific groups of patients (elderly patients, patients with renal function impairment or comorbidities), who are not fit for the standard cisplatin-based chemotherapy but can derive significant benefit from carboplatin- or taxane-based treatment. Retrospective analyses have enabled the identification of groups of patients with different prognoses, who possibly require different therapeutic approaches. Modern chemotherapy offers a chance of long-term survival in patients without visceral metastases, possibly in combination with definitive local treatment. Finally, the progress of targeted therapies in other neoplasms seems to be reflected in advanced bladder cancer by recent studies indicating that biological agents can be combined with modern chemotherapy. The true role of such therapies is currently being evaluated. PMID:16303860

    Metastatic renal carcinoma is the third most common source of ocular and second most common source of orbital metastases. This is the first published case of von Hippel-Lindau (vHL) disease that developed renal cell carcinoma metastatic to an eye with a retinal hemangioblastoma. A 73-year-old woman had a history of vHL disease that included prior retinal hemangioblastomas, 2 cerebellar hemangioblastomas, and bilateral renal cell carcinomas with sacral metastasis. After presenting with progressive, painful proptosis secondary to a large mass observable by ocular CT, an enucleation-orbitotomy was performed, and the surgical specimen was sent for histopathological analysis. The ophthalmic renal metastatic tumor, like the primary tumor, was a clear cell variant that involved both the eyeball and orbit in continuity. The intraocular component was larger than the extraocular portion, which was interpreted as an outward extension of an initial retinal metastasis that probably first settled within a hemangioblastoma. Clusters of ectatic ghost vessels with thickened walls produced by periodic acid Schiff-positive, redundant basement membrane material were partially infiltrated by tumor cells at their periphery, thereby lending some support for this hypothesis. Immunohistochemical positivity for the biomarkers cytokeratin 18, vimentin, carbonic anhydrase IX, PAX2, and PAX 8 confirmed the diagnosis. The patient has refused further treatment. Her anophthalmic socket has comfortably retained a porous polyethylene implant without clinical evidence of local recurrence during 5 months of follow up. PMID:24828963

    Worldwide, gastric cancer represents the fifth most common cancer and the third leading cause of cancer deaths. Although the overall 5-year survival for resectable disease was more than 70% in Japan due to the implementation of screening programs resulting in detection of disease at earlier stages, in Western countries more than two thirds of gastric cancers are usually diagnosed in advanced stages reporting a 5-year survival rate of only 25.7%. Anyway surgical resection with extended lymph node dissection remains the only curative therapy for non-metastatic advanced gastric cancer, while neoadjuvant and adjuvant chemotherapies can improve the outcomes aimed at the reduction of recurrence and extension of survival. High-quality research and advances in technologies have contributed to well define the oncological outcomes and have stimulated many clinical studies testing multimodality managements in the advanced disease setting. This review article aims to outline and discuss open issues in current surgical management of advanced gastric cancer. PMID:26632080

    The purpose of this review was to evaluate the impact of epidermal growth factor receptor (EGFR) mutation status on disease recurrence in patients treated with chemoradiotherapy (CRT) for locally advanced non–small cell lung cancer (NSCLC). A literature search was conducted and a total of three studies were analyzed. There was no significant difference in the objective response rate between the EGFR mutation group and the EGFR wild-type group (odds ratios [OR] 1.46, 95% CI, 0.79–2.70, P = 0.228), and there was no significant difference in the incidence of disease recurrence (OR 1.37, 95% CI, 0.68–2.75, P = 0.379) between the two groups. There were significant difference in the incidence of local/locoregional progression (LP) (OR 0.35, 95% CI, 0.18–0.71, P = 0.003) and distant progression (DP) (OR 2.97, 95% CI, 1.59–5.54, P < 0.001). Brain metastasis (BM) was one of the main recurrence patterns of DP, and the incidence was significantly higher in the EGFR mutant group (OR 2.75, 95% CI, 1.43–5.31, P = 0.003). There were no statistically significant heterogeneities in these pooled analyses. The patterns of recurrence after CRT for locally advanced NSCLC were different according to EGFR mutation status. LP after CRT in patients with EGFR mutation was less frequent, but the high incidence of DP, especially BM, continued to be the major problem. On the other hand, LP continued to be the major problem in EGFR wild-type patients. In multimodality treatment for inoperable locally advanced NSCLC, we may need to consider different treatment strategies according to EGFR mutation status. PMID:27534790

    An exploratory phase II biomarker-embedded trial (LPT109747; NCT00526669) designed to determine the association of lapatinib-induced fluoropyrimidine gene changes with efficacy of lapatinib plus capecitabine as first-line treatment for advanced gastric cancer or gastroesophageal junction adenocarcinoma independent of tumor HER2 status. Tumor biopsies obtained before and after 7-day lapatinib (1,250 mg) to analyze changes in gene expression, followed by a 14-day course of capecitabine (1,000 mg/m(2) twice daily, 14/21 days) plus lapatinib 1,250 mg daily. Blood samples were acquired for pharmacokinetic analysis. Primary clinical objectives were response rate (RR) and 5-month progression-free survival (PFS). Secondary objectives were overall survival (OS), PFS, time to response, duration of response, toxicity, and identification of associations between lapatinib pharmacokinetics and biomarker endpoints. Primary biomarker objectives were modulation of 5-FU-pathway genes by lapatinib, effects of germline SNPs on treatment outcome, and trough steady-state plasma lapatinib concentrations. Sixty-eight patients were enrolled; (75% gastric cancer, 25% gastroesophageal junction). Twelve patients (17.9%) had confirmed partial response, 31 (46.3%) had stable disease, and 16 (23.9%) had progressive disease. Median PFS and OS were 3.3 and 6.3 months, respectively. Frequent adverse events included diarrhea (45%), decreased appetite (39%), nausea (36%), and fatigue (36%). Lapatinib induced no changes in gene expression from baseline and no significant associations were found for SNPs analyzed. Elevated baseline HER3 mRNA expression was associated with a higher RR (33% vs. 0%; P = 0.008). Lapatinib plus capecitabine was well tolerated, demonstrating modest antitumor activity in patients with advanced gastric cancer. The association of elevated HER3 and RR warrants further investigation as an important player for HER-targeted regimens in combination with capecitabine. Mol Cancer Ther

    Highlights: •The patients underwent the second FDG PET during the early stage of concurrent chemoradiotherapy (CCRT). •To our knowledge, this could be the first study showing that the repeated FDG PET during the early stage of CCRT has added value by being a prognostic factor for recurrence of the locally advanced NSCLC patients. •This is a result of continuous research. •The decrease of MTV was the only significant risk factor for recurrence. -- Abstract: Purpose: The aim of this study is to investigate the value of [{sup 18}F] fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F FDG PET/CT) to predict recurrence of patients with locally advanced non-small cell lung cancer (NSCLC) during the early stage of concurrent chemoradiotherapy (CCRT). Methods: A total of 53 stage III NSCLC patients without diabetics or undergoing surgery were enrolled in the prospective study. Those patients were evaluated by FDG PET before and following 40 Gy radiotherapy (RT) with a concurrent cisplatin-based heterogeneous chemotherapy regimen. Semiquantitative assessment was used to determine maximum and mean SUVs (SUVmax/SUVmean) and metabolic tumor volume (MTV) of the primary tumor. The prognostic significance of PET/CT parameters and other clinical variables was assessed using Cox regression analyses. The cutoffs of PET/CT parameters which have been determined by the previous study were used to separate the groups with Kaplan–Meier curves. Results: Recurrence rates at 1- and 2-years were 18.9% (10/53) and 50.9% (27/53) for all patients, respectively. Cox regression analysis showed that the only prognostic factor for recurrence was a decrease of MTV. Using the cutoff of 29.7%, a decrease of MTV can separate the patients into 2 groups with Kaplan–Meier curve successfully. Conclusion: The prospective study has reinforced the early predictive value of MTV in repeated {sup 18}F-FDG PET/CT for recurrence in a subgroup of locally advanced NSCLC who

    Full Text Available Postsurgical survival is considered to be indicators of treatment efficiency in most cases. However, the sociomedical rehabilitation of patients in this group is no less important; not only life expectancy, but also functional rehabilitation and quality of life are in the lead in patients with Stage III–IVA due to their low 2-year and much lower 5-year survival. The main efficiency criterion is patients, quality of life as compared to antitumor treatment programs in the absence of differences in survival.As the only chance of cure or life prolongation in most cases, multicomponent surgery for locally advanced and recurrent oropharyngeal cancer may be refused by a patient for fear of being lost to society. Identification of surgical treatment-induced changes in quality of life in patients may be used as a criterion for assessing the performed operations.The body's changes in a patient with otopharyngeal cancer are associated with impairment of basic physiological functions (deglutition, mastication, and breathing, sensitivity (taste, olfaction, and hearing, and individual characteristics of a human being (for example, appearance and voice. The quality of life is integral characteristics of the physical, psychological, emotional, and social functioning of a patient, which is based on his subjective perception. The methods for studying the quality of life include first of all questionnaires that are classified as general and special ones.The general questionnaires are intended to assess the quality of life of both healthy individuals and patients regardless of their disease; the special questionnaires are used to study that in certain categories and groups of patients. The general questionnaires allow the comparison of patients with a population of healthy people. Account must be also taken of the fact that the quality of life varies with age and comorbidities.

    Full Text Available Abstract Background We previously reported that survivin-2B, a splicing variant of survivin, was expressed in various types of tumors and that survivin-2B peptide might serve as a potent immunogenic cancer vaccine. The objective of this study was to examine the toxicity of and to clinically and immunologically evaluate survivin-2B peptide in a phase I clinical study for patients with advanced or recurrent breast cancer. Methods We set up two protocols. In the first protocol, 10 patients were vaccinated with escalating doses (0.1–1.0 mg of survivin-2B peptide alone 4 times every 2 weeks. In the second protocol, 4 patients were vaccinated with the peptide at a dose of 1.0 mg mixed with IFA 4 times every 2 weeks. Results In the first protocol, no adverse events were observed during or after vaccination. In the second protocol, two patients had induration at the injection site. One patient had general malaise (grade 1, and another had general malaise (grade 1 and fever (grade 1. Peptide vaccination was well tolerated in all patients. In the first protocol, tumor marker levels increased in 8 patients, slightly decreased in 1 patient and were within the normal range during this clinical trial in 1 patient. With regard to tumor size, two patients were considered to have stable disease (SD. Immunologically, in 3 of the 10 patients (30%, an increase of the peptide-specific CTL frequency was detected. In the second protocol, an increase of the peptide-specific CTL frequency was detected in all 4 patients (100%, although there were no significant beneficial clinical responses. ELISPOT assay showed peptide-specific IFN-γ responses in 2 patients in whom the peptide-specific CTL frequency in tetramer staining also was increased in both protocols. Conclusion This phase I clinical study revealed that survivin-2B peptide vaccination was well tolerated. The vaccination with survivin-2B peptide mixed with IFA increased the frequency of peptide-specific CTL more

    Full Text Available Thomas J Polascik, Vladimir MouravievDuke Prostate Center and Division of Urologic Surgery, Duke University Medical Center, Durham, NC, USAAbstract: Many patients with advanced cancer experience decreased bone strength due to metastatic foci, underlying osteoporosis and/or cancer treatment induced bone loss. The clinical consequences of metastatic disease involving the skeleton are widespread. This review focuses on the efficacy, pharmacology, and safety when using intravenous biphosphonate such a zoledronic acid for cancer bone metastases. Zoledronic acid is the gold standard for the medical management of metastatic bone disease. The indications for treatment include prevention of skeletal relevant events (SRE, osteoporotic complications, and palliation of bone pain, among others. Zoledronic acid is the only bisphosphonate effective in decreasing SREs associated with bone metastases from advanced renal cell carcinoma and prostate cancer. Regarding prostate cancer, zoledronic acid effectively prevents both bone loss in patients with locally advanced disease receiving androgen deprivation therapy and SREs in men with hormone-refractory or hormonesensitive metastatic disease. Zoledronic acid has an acceptable safety profile and tolerability, and has been effective at significantly decreasing the incidence, delaying the onset, and reducing the overall risk of experiencing an SRE compared to placebo. It is the only bisphosphonate currently approved for the prevention and treatment of skeletal complications in patients with bone metastases due to all solid tumors.Keywords: zoledronic acid, metastatic bone disease, osteoporosis, skeletal relevant events, advanced prostate cancer

Although most sarcomas are localized, many display a remarkable predilection for metastasis to the lungs, liver, bones, subcutaneous tissue, and lymph nodes. Additionally, many sarcoma patients presenting initially with localized disease may relapse at metastatic sites. While localized sarcomas can often be cured through surgery and often radiation, controversies exist over optimal management of patients with metastatic sarcoma. Combinations of chemotherapy are the most effective in many settings, and many promising new agents are under active investigation or are being explored in preclinical models. Metastatic sarcomas are excellent candidates for novel approaches with additional agents as they have demonstrated chemosensitivity and affect a portion of the population that is motivated toward curative therapy. In this paper, we provide an overview on the common sarcomas of childhood (rhabdomyosarcoma, adolescence, and young adults (osteosarcoma, Ewing sarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor and older adults (leiomyosarcoma, liposarcoma, and undifferentiated high grade sarcoma in terms of the epidemiology, current therapy, promising therapeutic directions and outcome with a focus on metastatic disease. Potential advances in terms of promising therapy and biologic insights may lead to more effective and safer therapies; however, more clinical trials and research are needed for patients with metastatic sarcoma.

    Objective To investigate the therapeutic effect,safety and its prognostic factors of capecitabine as maintenance treatment agent for prolonging the PFS of patients with recurrent and metastatic breast cancer after they received combination chemotherapy.Methods From January 2011 to June 2013,38 cases with recurrent and metastatic breast cancer were collected in the department of medical oncology of the First Hospital of Lanzhou University.All the 38 patients received NX scheme (vinorelbine combined capecitabine chemotherapy),and some patients among of them had stabile disease after chemotherapy and were administered X scheme (capecitabine,twice a day,2 000 mg/m2 daily,withdrawal for 7 days after a consecutive intake of 14 days,21 days as a cycle,at least 2 cycles) until disease progressed or toxicity could not be tolerated.Adverse reactions and PFS were observed and recorded.Single factor chi square test and multivariate COX proportion hazard model were used to evaluate the relationships between clinic features and RR,PFS.Results The overall response rate (CR + PR) was 55.26% (21/38),clinical benefit patients rate (CR + PR + SD) was 84.2% (32/38),with 4 patients of CR (4/32),17 patients of PR,11 patients of SD,6 patients of PD.Thirty-two no progressived patients were administered capecitabine until PD.The median PFS was 10.0 months.Stratification analysis showed that patients whose Karnofsky (KPS) ≥80 had an average PFS of 14.1 months,while an average PFS of 6.8 months for patients whose KPS < 80,with a statistical significance (x2 =6.251,P =0.000).Cox proportion hazard model also showed that age (RR =3.561,95% CI:1.372-5.216,.x2 =4.025,P =0.031),menopausal status (RR =1.895,95 % CI:1.124-4.452,x2 =5.725,P =0.048),KPS score (RR =4.553,95% CI:1.131-7.703,x2 =11.205,P =0.005),the number of metastasis (RR =5.781,95% CI:2.321 ~11.243,x2 =3.925,P =0.011) were important prognostic factors for the patients with breast cancer.Major treatment

  6. Novel Insights of Oligometastases and Oligo-Recurrence and Review of the Literature

    2012-01-01

    Full Text Available Oligometastases and oligo-recurrence are among the most important notions of metastatic and recurrent cancer. The concept of oligometastases is related to the notion that cancer patients with 1–5 metastatic or recurrent lesions that could be treated by local therapy achieve long-term survival or cure, while the concept of oligo-recurrence is related to the notion that cancer patients with 1–5 metastatic or recurrent lesions that could be treated by local therapy have controlled primary lesions. Achievement of long-term survival or cure in patients with oligometastases and oligo-recurrence is cancer and organ specific. These facts rely on the seed and soil theory and multiple steps of cancer progression. Oligo-recurrence is considered to have a better prognosis than oligometastases. In patients with oligometastases and oligo-recurrence, the oligometastases and oligo-recurrence are sometimes cured with only local therapy, which is an example of the abscopal effect, previously described in relation to cure of lesions outside of the field of radiation therapy without systemic therapy. Oligometastases and oligo-recurrence can now be cured by less invasive local treatment methods combined with systemic therapy. The mechanisms of oligometastases and oligo-recurrence, as well as novel insights into these important concepts, are presented in this paper.

    Traditionally, androgen deprivation therapy (ADT) has been the standard initial treatment for metastatic hormone-sensitive prostate cancer (mHSPC), with chemotherapy utilized in the castration-resistant setting. Data reported from three recent clinical trials shed new light on the role of upfront docetaxel in advanced or mHSPC. Two of these studies-CHAARTED and STAMPEDE-showed significant improvement in overall survival, while the third study, GETUG-AFU 15, showed no statistical difference. The CHAARTED study showed a 13.6-month survival improvement and the STAMPEDE study showed a 10-month survival improvement with ADT plus docetaxel, compared with ADT alone, in the hormone-sensitive setting. These numbers are remarkable when compared with the 2.9-month survival benefit from docetaxel in the metastatic castration-resistant setting, which has been the standard setting for the use of docetaxel in advanced prostate cancer. In this review, we describe the historical data for chemotherapy in the perioperative and metastatic prostate cancer settings, and the recent trials that are changing the paradigm in support of docetaxel in the upfront setting.

    Chordoma is a rare, slow-growing malignant tumor arising from notochordal remnants. A retrospective review of patient records at two major referral centers was undertaken to assess the incidence, location, and prognostic factors of metastatic disease from chordoma. 219 patients with chordoma (1962–2009) were identified. 39 patients (17.8%) developed metastatic disease, most frequently to lung (>50%). Median survival from the time of initial diagnosis was 130.4 months for patients who developed metastatic disease and 159.3 months for those who did not (P = 0.05). Metastatic disease was most common in the youngest patients (P = 0.07), and it was 2.5 times more frequent among patients with local recurrence (26.3%) than in those without (10.8%) (P = 0.003). Patient survival with metastatic disease was highly variable, and it was dependent on both the location of the tumor primary and the site of metastasis. Metastasis to distal bone was the most rapid to develop and had the worst prognosis. PMID:26843835

    Basaloid squamous cell carcinoma (BSC) of the esophagus is a rare malignant disease. We report here a patient with recurrent esophageal BSC, who was successfully treated by systemic chemotherapy containing 5-fluorouracil (5-FU) and cisplatin (CDDP). A 57-year-old woman was diagnosed as having squamous cell carcinoma of the esophagus upon endoscopic examination. Curative esophagectomy with lymph node dissection was performed under the thoracoscope. The pathological diagnosis of the surgical specimen was BSC.Five months after operation, the patient was diagnosed as having a recurrence of the BSC with metastases to the liver and spleen, and a right paraclavicular lymph node. She was given systemic chemotherapy consisting ofcontinuous infusion of 800 mg/d of 5-FU and 3 h infusion of 20 mg/d of CDDP for 5 consecutive days every 4 wk. The metastatic lesions in the spleen and right paraclavicular lymph node disappeared, and the liver metastasis was apparently reduced in size after 2 courses of chemotherapy. The tumor regression was seen over 6 courses, with progression afterwards.Although subsequent treatment with CPT-11 and CDDP was not effective, docetaxel and vinorelbine temporarily controlled the tumor growth for 2 mo. 5-FU and CDDP combination may be useful for the patients with advanced BSC.

    Objective To retrospectively analyze the efficacy, safety and prognostic factors affecting responses of imatinib mesylate as the first-line therapy for Chinese patients with recurrent or metastatic gastrointestinal stromal tumors (GISTs). Methods Patients treated with imatinib mesylate 400mg daily as the first-line treatment from Apr. 2003 to Mar. 2012 were followed up. Short-term efficacy was evaluated according to RECIST version 1. 0 criteria and toxicity according to NCI CTC version 3. 0 criteria. Relative factors affecting time to progress (TTP) and overall survival (OS) were stratified analyzed using SPSS 13.0 software. Results Totally there were 105 cases enrolled in this retrospective analysis, with median following-up duration of 126 months(range; 44-348months) , meanwhile 36 patients died during the period. The response rate was 66. 6% and disease control rate was 79. 9% , including 8(7. 6% ) cases of CR, 62(59. 0% ) of PR, 14( 13. 3% ) of SD and 21 cases(20. 0% ) of PD. Median TTP and OS of all cases were 61. 5months and 60.0 months (95% CI: 52. 1-67.8 months), respectively. After being stratified, cases were enlisted into three comparative groups: adjuvant or not groups, second-line or not groups and treatment discontinued or not groups. TTP and OS of patients in adjuvant or second-line groups had no significant differences compared with "not" groups. Contrarily, TTP and OS of patients with treatment discontinued for 3-12months was significantly decreased compared with discontinued less than 3 months(P <0. 05) or continued group (P < 0. 05 ) , while no difference observed between latter two groups. Common toxicities were fatigue, skin mucosal edema, leukope-nia, diarrhea, etc. Mainly in grade 1-2, with no treatment-related death. Conclusion Imatinib mesylate 400mg daily as the first-line therapy for patients with recurrent or metastatic GISTs was safety and effective.

    Recurrent oral ulcer (ROU) represents a very common but poorly understood mucosal disorder.It can occur in men and women of all ages, races and geographic regions. It is estimated that at least 1 in 5 individuals has at least once been afflicted with recurrent oral ulcer. Attacks may be precipitated by local trauma,stress, food intake, drugs, hormonal changes and vitamin and trace element deficiencies. However, to date, no principal cause has been discovered. There is no curative therapy to prevent the recurrence of ulcers, and all available therapies can only reduce the frequency or severity of the lesions. In order to provide a valuable reference for clinical treatment, in this article we collected and analyzed the reports about recurrent oral ulceration recently,and make a review of treatments for recurrent oral ulceration.%复发性口腔溃疡(recurrent oral ulcer,ROU)是最常见的口腔黏膜病,不同性别、不同年龄阶段、不同种族、不同地域的人都可能患病.一般人群的患病率可高达20%.复发性口腔溃疡病因尚不明确,可能与局部创伤、压力、饮食、药物、激素以及维生素和微量元素缺乏等因素有关.目前仍无根治复发性口腔溃疡的特效方法,只能减少复发次数,延长间隙期,减轻疼痛,促进愈合.为了更好地指导临床合理用药,笔者对近几年有关复发性口腔溃疡的治疗方法进行了整理和分析,对复发性口腔溃疡的临床治疗进行介绍.

    Full Text Available Metastatic tumor is secondary spread to the central nervous system of primer systemic cancers originating from tissues other than the central nervous system. In adults; there are metastases respectively from lungs, breasts, malign melanoma, renal cell carcinoma, colon and thyroid cancers. 30-60% of lung cancers metastasis to the brain. In children there are quite a few cerebral metastases. Most commonly leukemia, lymphoma, osteogenic sarcoma, rhabdomyosarcoma and germ cell tumors metastasis to the brain. %50 of malign melanoma, lung, breast and colon cancers intend to make multipl metastases but renal cell cancers intend to make solitary metastasis.While lung cancers metastasis to brain in 6-9 months after the definitive diagnosis, renal cancers in 1 year, colon cancers in 2 years, breast cancers and malign melanoma in 3 years metastasis to brain. In 6% of cases there are cerebral metastasis while there isn’t a symptom of a primary tumor. For treatment corticosteroids, surgery, Radiotherapy(RT, Chemotherapy(CT and Stereotactic Radiosurgery(SRS can be implemented. Small cell lung cancers, lymphoma, germ cell tumors are sensitive to RT and CT. Non small cell lung cancers, renal, colon cancers and malign melanoma are radioresistant. The purposes in the surgery of the metastatic brain tumors are; total resection of tumors without neurologic deficits, decreasing the intracranial pressure and decreasing the dose of postoperative radiotherapy.

    The clinical management of metastatic (stage Ⅳ)colorectal cancer (CRC) is a common challenge faced by surgeons and physicians. The last decade has seen exciting developments in the management of CRC, with significant improvements in prognosis for patients diagnosed with stage Ⅳ disease. Treatment options have expanded from 5-fluorouracil alone to a range of pharmaceutical and interventional therapies,improving survival, and providing a cure in selected cases. Enhanced understanding of the biologic pathways most important in colorectal carcinogenesis has led to a new generation of drugs showing promise in advanced disease. It is hoped that in the near future the treatment paradigm of metastatic CRC will be analogous to that of a chronic illness, rather than a rapidly terminal condition.This overview discusses the epidemiology of advanced CRC and currently available therapeutic options including medical, surgical, ablative and novel modalities in the management of metastatic colorectal cancer.

    Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer of trastuzumab emtansine (T-DM1) (Kadcyla(®); Roche) to submit evidence of its clinical and cost-effectiveness for treating human epidermal growth factor receptor 2 (HER2)-positive, unresectable, locally advanced or metastatic breast cancer after treatment with trastuzumab and a taxane. The School of Health and Related Research Technology Appraisal Group (ScHARR-TAG) at the University of Sheffield were the independent Evidence Review Group (ERG) who produced a critical review of the company's submission to NICE. The ERG also independently searched for relevant evidence and modified the submitted decision analytic model to produce a revised estimate of cost-effectiveness and examine the impact of altering some of the key assumptions. The clinical effectiveness data were taken from two randomised controlled trials that reported a significant advantage in progression-free survival (PFS) for T-DM1 over lapatinib in combination with capecitabine (EMILIA trial), and over the treatment of physician's choice (TH3RESA trial). A network meta-analysis suggested T-DM1 was the best treatment in terms of both overall survival and PFS compared with lapatinib in combination with capecitabine; trastuzumab in combination with capecitabine; and capecitabine monotherapy. Adverse event (AE) data were taken from a pooled analysis of additional trials of T-DM1 as a single agent. The most common grade 3 or greater AEs for T-DM1 were thrombocytopenia and hepatotoxicity. Following the clarification process, the manufacturer reported a deterministic incremental cost-effectiveness ratio (ICER) for T-DM1 compared with lapatinib in combination with capecitabine of £167,236, the latter of which was estimated to have an ICER of £49,798 compared with capecitabine monotherapy. The ERG produced similar values of £166,429 and £50,620 respectively. All other comparators were dominated. During the appraisal, the

    Cancers of esophagus and stomach are common malignant diseases worldwide, and they are associated with serious morbidity and high mortality rates. When diagnosed at an early stage, gastro-esophageal cancers are potentially curable. Neo-adjuvant or adjuvant therapies using both chemotherapy and radiation therapy have been shown to reduce the risk of local recurrence and distant metastasis. For advanced or metastatic tumors, systemic chemotherapy offers symptomatic palliation and moderate benefits in survival. With recent advances in anti-cancer therapeutics, progress has been made to improve treatment response and life expectancy in patients with advanced gastro-esophageal cancers. Furthermore, the clinical use of molecularly targeted agents in combination with cytotoxic chemotherapeutics is being evaluated in a number of ongoing clinical trials. In this article, we review currently used standard systemic therapies including recently evolving targeted therapies for metastatic gastro-esophageal cancers, as well as the proven role and the regimens that are used as neoadjuvant and adjuvant treatment in localized gastro-esophageal cancers.

  20. Cerebral relapse of metastatic gastrointestinal stromal tumor during treatment with imatinib mesylate: Case report

    Full Text Available Abstract Background The management of unresectable or metastatic gastrointestinal stromal tumors (GISTs has previously been difficult as they are resistant to conventional chemotherapy and radiation. The development of imatinib mesylate has made a major impact on the management of advanced GISTs. It is apparent that there are sanctuary sites such as the central nervous system where imatinib does not achieve adequate concentrations. We describe the case of a man with metastatic GIST who experienced multiple cerebral relapses of disease while systemic disease progression appeared to be controlled by imatinib. Case presentation A 47-year-old man presented in July 1999 with a jejunal GIST with multiple hepatic metastases. The jejunal primary was resected and after unsuccessful cytoreductive chemotherapy, the liver metastases were also resected in December 1999. The patient subsequently relapsed in August 2001 with symptomatic hepatic, subcutaneous gluteal, left choroidal and right ocular metastases all confirmed on CT and PET scanning. Biopsy confirmed recurrent GIST. MRI and lumbar puncture excluded central nervous system involvement. The patient was commenced on imatinib 400 mg bd in September 2001 through a clinical trial. The symptoms improved with objective PET and CT scan response until December 2002 when the patient developed a right-sided foot drop. MRI scan showed a left parasagittal tumor which was resected and confirmed histologically to be metastatic GIST. Imatinib was ceased pre-operatively due to the trial protocol but recommenced in February 2003 on a compassionate use program. The left parasagittal metastasis recurred and required subsequent re-excision in September 2003 and January 2004. Control of the systemic GIST was temporarily lost on reduction of the dose of imatinib (due to limited drug supply but on increasing the dose back to 800 mg per day, systemic disease was stabilized for a period of time before generalised progression

    The two combination chemotherapy regimens FOLFIRINOX and gemcitabine plus nab-paclitaxel represent major breakthroughs in the management of metastatic pancreatic cancer. Both regimens showed unprecedented survival advantage in the setting of front-line therapy. However, their application for treatment of patients in the community is challenging because of significant toxicities, thus limiting potential benefits to a narrow population of patients. Modifications to the dose intensity or schedule of those regimens improve their tolerability, while likely retaining survival advantage over single-agent chemotherapy. Newer strategies to optimize these two active regimens in advanced pancreatic cancer are being explored that can help personalize treatment to individual patients.

    2011-02-01

    Full Text Available According to the concept of tumor dormancy, tumor cells may exist as single cells or microscopic clusters of cells that are clinically undetectable, but remain viable and have the potential for malignant outgrowth. At metastatic sites, escape from tumor dormancy under more favorable local microenvironmental conditions or through other, yet undefined stimuli, may account for distant recurrence after supposed “cure” following surgical treatment of the primary tumor. The vast majority of evidence to date in support of the concept of tumor dormancy originates from animal studies; however, extensive epidemiologic data from breast cancer strongly suggests that this process does occur in human disease. In this review, we aim to demonstrate that metastatic tumor dormancy does exist in cutaneous melanoma based on evidence from mouse models and clinical observations of late recurrence and occult transmission by organ transplantation. Experimental data underscores the critical role of impaired angiogenesis and immune regulation as major mechanisms for maintenance of tumor dormancy. Finally, we examine evidence for the role of surgery in promoting escape from tumor dormancy at metastatic sites in cutaneous melanoma.

    Extraskeletal myxoid chondrosarcoma (EMC) is a lowgrade sarcoma characterized by developing metastases and local recurrence in high rate. It is mainly deep seated in the proximal extremities. The most common metastatic sites are the lungs, soft tissues, lymph nodes, bones and the brain. To our knowledge, no case of clearly defined EMC has been reported to date developing a metastasis in the pancreas. We describe a case of a man suffering from EMC who developed a single pancreatic metastasis 20 years after the initial diagnosis. A 49-year-old man was submitted to surgical excision of an EMC, in left thigh, 20 years ago. Fourteen years after the initial diagnosis a local recurrence in left thigh occurred. Multiple lesions of metastatic origin, in both lungs, were excised via thoracotomies until the time being. In 2003, as a part of a periodically performed imaging control, an abdominal CT scan was performed revealing a solid lesion in the pancreas. Distal pancreatectomy was performed. The histopathology of the excised specimen proved to be the one of metastatic lesion of EMC. The above-mentioned case of EMC is, as far as we know, the first one described developing a certain pancreatic metastasis.

  6. Somatic Copy Number Abnormalities and Mutations in PI3K/AKT/mTOR Pathway Have Prognostic Significance for Overall Survival in Platinum Treated Locally Advanced or Metastatic Urothelial Tumors.

    Directory of Open Access Journals (Sweden)

    Joaquim Bellmunt

    Full Text Available An integrative analysis was conducted to identify genomic alterations at a pathway level that could predict overall survival (OS in patients with advanced urothelial carcinoma (UC treated with platinum-based chemotherapy.DNA and RNA were extracted from 103 formalin-fixed paraffin embedded (FFPE invasive high-grade UC samples and were screened for mutations, copy number variation (CNV and gene expression analysis. Clinical data were available from 85 cases. Mutations were analyzed by mass-spectrometry based on genotyping platform (Oncomap 3 and genomic imbalances were detected by comparative genomic hybridization (CGH analysis. Regions with threshold of log2 ratio ≥0.4, or ≤0.6 were defined as either having copy number gain or loss and significantly recurrent CNV across the set of samples were determined using a GISTIC analysis. Expression analysis on selected relevant UC genes was conducted using Nanostring. To define the co-occurrence pattern of mutations and CNV, we grouped genomic events into 5 core signal transduction pathways: 1 TP53 pathway, 2 RTK/RAS/RAF pathway, 3 PI3K/AKT/mTOR pathway, 4 WNT/CTNNB1, 5 RB1 pathway. Cox regression was used to assess pathways abnormalities with survival outcomes.35 samples (41% harbored mutations on at least one gene: TP53 (16%, PIK3CA (9%, FGFR3 (2%, HRAS/KRAS (5%, and CTNNB1 (1%. 66% of patients had some sort of CNV. PIK3CA/AKT/mTOR pathway alteration (mutations+CNV had the greatest impact on OS (p=0.055. At a gene level, overexpression of CTNNB1 (p=0.0008 and PIK3CA (p=0.02 were associated with shorter OS. Mutational status on PIK3CA was not associated with survival. Among other individually found genomic alterations, TP53 mutations (p=0.07, mTOR gain (p=0.07 and PTEN overexpression (p=0.08 have a marginally significant negative impact on OS.Our study suggests that targeted therapies focusing on the PIK3CA/AKT/mTOR pathway genomic alterations can generate the greatest impact in the overall patient

    Metastatic colorectal cancer to the liver is associated with a uniform poor prognosis without treatment. Advances in therapy over the past decades have now allowed surgical resections of the liver to occur with a low morbidity and mortality. Improvements in chemotherapy regimes have paralleled technical improvements and now allow a new group of patients to become eligible for surgical resection. This chapter will review the recent advances in surgical and chemotherapeutic regimes in metastatic colorectal cancer to the liver.

    2014-05-01

    Recurrences of tumours of the upper aerodigestive tract are frequent despite the improvement of the primary treatment and they limit the rate of survival long-term. They occur in patients with multiple co-morbidities, often associated with sequelae or side effects of earlier treatments. The salvage treatment will add a cumulative toxicity and therapeutic options are limited. The choice will go from curator to palliative treatment. The report benefit-risk must be assessed in each case depending on the terrain and prognostic factors that have been identified, such as performance status, the time between initial disease and the recurrence, the site and the stratification of the recurrence. In operable non-metastatic recurrence surgery remains the treatment of choice. Multimodal treatment involving surgery, radiation therapy and chemotherapy in this context is being evaluated. Non-operable tumors have long been considered only in a palliative context. The evaluation of detailed irradiation as bifractionnated radiotherapy combined with chemotherapy helped establish protocols allowing long-term survivals and consider these treatments as potentially curators. However, the toxicity of these treatments is important. That is why the technical innovations of the radiation and the development of new chemotherapeutic agents today offer opportunities remaining to assess. The use of irradiation targeted by intensity-modulated radiation therapy (IMRT), and stereotactic radiotherapy by decreasing the irradiated volume should decrease the toxicity. Generally better tolerated than conventional chemotherapy agents, targeted therapies also took their places associated with radiotherapy in the treatment of these patients already treated. Cetuximab was the first agent obtaining an indication. Other agents are being evaluated in metastatic recurrent tumors, including exploring the possibilities of radiopotentialisation nanoparticles and the inhibitors of apoptosis proteins.

    2010-01-01

    Recent advances in the understanding of the metastatic phenomenon in cancer have led to the description of a metastatic niche. This concept describes a site prepared for the tumor cells in areas frequently associated with metastasis for the individual tumor studied. This niche is a “soil” that allows for the tumor cell or “seed” to lodge and grow. Certain aspects of the biology of infantile hemangioma cells suggest a relationship to the placenta as a possible site of origin for the hemangioma...

    The aging of the population, along with rising life expectancy, means that increasing numbers of older men will be diagnosed with prostate cancer, and a large proportion of these men will present with metastatic disease. In this paper, we discuss recent advances in prostate cancer treatment. In particular, we review management approaches for older patients with metastatic prostate cancer based on the decision tree developed by the International Society of Geriatric Oncology, which categorized older men as "fit," "vulnerable," and "frail" according to comprehensive geriatric assessment.

    Purpose: The purpose of this study was to evaluate local transarterial chemoperfusion (TACP) in locally recurrent pancreatic carcinoma and advanced tumor stages which did not respond to prior systemic chemotherapy. The tumor response, survival, and pain response were retrospectively analyzed. Materials and method: Forty outpatients (median age 62 years, range 36 - 79) were treated with a minimum of 3 (mean 6, range 3 - 12) applications per patient in four-week intervals. Twenty-eight patients were in advanced tumor stages, and 12 patients had locally recurrent tumors. Gemcitabine (1,000 mg/m{sup 2}) and mitomycin C (8.5 mg/m{sup 2}) were administered within 1 hour through a celiac trunk catheter. The tumor response (diameter, volume) was measured using MRI or CT and classified according to RECIST. The pain response was defined as a reduction of pain intensity of more than 50% on a visual analog scale, or a reduction of more than 50% in analgesics consumption, or a switch to a less potent analgesic agent. Results: The treatment was tolerated well by all patients. No clinically relevant problems or grade III or IV toxicity according to CTC (Common Toxicity Criteria) were observed. Tumor-related pain was relieved in 20/32 (62.5%) cases. Radiologically, 'complete response' was found in 3/40 (7.5%), 'partial response' in 9/40 (22.5%), 'stable disease' in 16/40 (40%), and 'progressive disease' in 12/40 (30%) of the patients. The median survival period since initial diagnosis and first TACP was 16.4 months and 8.1 months, respectively. Locally recurrent tumors showed better, but still not significant results regarding tumor response (41.7% vs. 25%) as well as survival (14.4 vs. 7 months) compared to advanced tumor stages. Responders (CR + PR) showed a significant survival advantage compared to patients with tumor progression (13.0 vs. 6.0 months; p = 0.013). (orig.)

    Full Text Available Conventional chemotherapy is associated with poor outcomes in metastatic renal cell carcinoma (RCC. Advances in the understanding of tumor molecular biology and the implementation of new drugs that target these molecular pathways have increased the arsenal against advanced RCC and improved outcomes in these patients. Herein, we briefly describe the latest data on targeted therapies used in the treatment of advanced renal cell carcinoma. Search strategy was performed according to PRISMA guidelines. Abstracts of relevant studies published in PubMed between 2000 and 2014 were analyzed by two authors. Abstracts were selected if they were published in English, data reported was of phase II or III clinical trials, and outcomes followed FDA approval.  If consensus between the two authors was achieved, they were included in the review. Key words used were “target therapy” and “metastatic renal cell carcinoma”. The results of the studies analyzed in this review support the benefits of targeted therapy in metastatic RCC. These include improved progression-free survival, overall survival, and quality of life as well as reduced toxicities compared to immunotherapy. The improvement in outcomes in metastatic RCC makes these drugs a preferred option as a primary treatment for these patients.

    Purpose: To evaluate results of medial patellofemoral ligament (MPFL) reconstruction associated with lateral release and advancement of vastus medialis in recurrent dislocation of the patella. Methods: We retrospectively evaluated 11 patients with a mean follow-up of 19 months. Mean age was 23, mainly women. We did MPFL reconstruction with semitendinosus or gracilis tendon depending on BMI, associated with advancement of vastus medialis and lateral release. Results: Mean Kujala score improved from 46,54 pts. preoperative to 88,36 postoperative. Our main complication was 1 patient with rigid knee, who required movilization under anesthesia and arthroscopic arthrolisis to improve her outcome. Conclusion: The combination of this techniques are a good alternative to treat patients with recurrent patella disclocation, with good short and mid-term results. Biomechanic intra and postop complications of MPFL reconstruction are related to patellar fixation, anatomic positioning of femoral tunnel and knee position of the graft fixation.

    Purpose: Recent in vitro and in vivo experimental findings provided strong evidence that pulsed low-dose-rate radiotherapy (PLDR) produced equivalent tumor control as conventional radiotherapy with significantly reduced normal tissue toxicities. This work aimed to implement a PLDR clinical protocol for the management of recurrent cancers utilizing IMRT and VMAT. Methods: Our PLDR protocol requires that the daily 2Gy dose be delivered in 0.2Gy×10 pulses with a 3min interval between the pulses. To take advantage of low-dose hyper-radiosensitivity the mean dose to the target is set at 0.2Gy and the maximum dose is limited to 0.4Gy per pulse. Practical planning strategies were developed for IMRT and VMAT: (1) set 10 ports for IMRT and 10 arcs for VMAT with each angle/arc as a pulse; (2) set the mean dose (0.2Gy) and maximum dose (0.4Gy) to the target per pulse as hard constraints (no constraints to OARs); (3) select optimal port/arc angles to avoid OARs; and (4) use reference structures in or around target/OARs to reduce maximum dose to the target/OARs. IMRT, VMAT and 3DCRT plans were generated for 60 H and N, breast, lung, pancreas and prostate patients and compared. Results: All PLDR treatment plans using IMRT and VMAT met the dosimetry requirements of the PLDR protocol (mean target dose: 0.20Gy±0.01Gy; maximum target dose < 0.4Gy). In comparison with 3DCRT, IMRT and VMAT exhibited improved target dose conformity and OAR dose sparing. A single arc can minimize the difference in the target dose due to multi-angle incidence although the delivery time is longer than 3DCRT and IMRT. Conclusion: IMRT and VMAT are better modalities for PLDR treatment of recurrent cancers with superior target dose conformity and critical structure sparing. The planning strategies/guidelines developed in this work are practical for IMRT/VMAT treatment planning to meet the dosimetry requirements of the PLDR protocol.

    Chordomas are primary low grade malignant tumors of bone that usually arise within both ends of axial skeleton. The Notochord is a midline, ectoderm-derived structure that defines the phylum of chordates. Chordomas may pose difficult diagnostic challenges when encountered in secondary locations, such as lungs or other parenchymatous organs. We report the cytologic findings of a metastatic chordoma sampled through CT-scan guided fine needle aspiration (FNA) of lower lobe lung nodule in a 54-year-old man diagnosed with recurrent chordoma involving the lumber spine and paraspinal region.

    BACKGROUND: Merkel cell cancer (MCC) is an uncommon neuroendocrine skin cancer occurring predominantly in elderly Caucasians. It tends to metastasize to regional lymph nodes and viscera and is sensitive to chemotherapy but recurs rapidly. AIM: To report one such case, its response to chemotherapy and briefly review the literature. METHODS: A 73-year-old male with a fungating primary lesion on his left knee and ulcerated inguinal lymph nodes was diagnosed with MCC and treated with chemotherapy. The two largest case series and reviews of case reports were summarised. RESULTS: His ulcer healed after two cycles of carboplatin and etoposide with improvement in quality of life. Overall response rates of nearly 60% to chemotherapy are reported but median survival is only nine months with metastatic disease. CONCLUSIONS: Chemotherapy should be considered for fit elderly patients with MCC who have recurrent or advanced disease.

    Full Text Available Heather L McArthur, Patrick G MorrisBreast Cancer Medicine Service, Department of Medicine, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: Despite ongoing therapeutic innovations, metastatic breast cancer (MBC remains a treatable but incurable disease. In the developed world, a diagnosis of MBC without a preceding diagnosis of early stage disease is a rare event. However, approximately one-third of women with early stage breast cancer ultimately experience a distant recurrence. Because the majority of breast cancers express estrogen and/or progesterone receptors and are accordingly considered hormone-sensitive, therapeutic strategies that interfere with hormone-mediated tumorigenesis have been a cornerstone of the breast cancer management paradigm for decades. Historically, the selective estrogen receptor modulator tamoxifen has been the most extensively studied and widely used hormone maneuver in breast cancer. However, a recent therapeutic innovation, namely the successful development of third-generation aromatase inhibitors (AIs, has had a dramatic impact on the treatment paradigm for women with hormone-sensitive MBC. Because of the demonstrated efficacy in postmenopausal breast cancer patients, the generally favorable side-effect profile, and the convenience of oral administration, AIs are now in widespread clinical use. Currently, there are three clinically available third-generation AIs: two reversible, nonsteroidal AIs, letrozole and anastrozole; and one irreversible, steroidal AI, exemestane. All three agents are at least as efficacious as tamoxifen as monotherapy for postmenopausal women with hormone-sensitive MBC. Current clinical research aims to improve upon existing strategies by evaluating AIs in combination with systemic chemotherapy regimens and/or novel targeted agents. It is hoped that these therapeutic innovations will lead to ongoing improvements in quality of life parameters and ideally survival for women

    Carolyn G Marsden

    Full Text Available BACKGROUND: Disseminated tumor cells (DTCs in the bone marrow may exist in a dormant state for extended periods of time, maintaining the ability to proliferate upon activation, engraft at new sites, and form detectable metastases. However, understanding of the behavior and biology of dormant breast cancer cells in the bone marrow niche remains limited, as well as their potential involvement in tumor recurrence and metastasis. Therefore, the purpose of this study was to investigate the tumorigenicity and metastatic potential of dormant disseminated breast cancer cells (prior to activation in the bone marrow. METHODOLOGY/PRINCIPAL FINDINGS: Total bone marrow, isolated from mice previously injected with tumorspheres into the mammary fat pad, was injected into the mammary fat pad of NUDE mice. As a negative control, bone marrow isolated from non-injected mice was injected into the mammary fat pad of NUDE mice. The resultant tumors were analyzed by immunohistochemistry for expression of epithelial and mesenchymal markers. Mouse lungs, livers, and kidneys were analyzed by H+E staining to detect metastases. The injection of bone marrow isolated from mice previously injected with tumorspheres into the mammary fat pad, resulted in large tumor formation in the mammary fat pad 2 months post-injection. However, the injection of bone marrow isolated from non-injected mice did not result in tumor formation in the mammary fat pad. The DTC-derived tumors exhibited accelerated development of metastatic lesions within the lung, liver and kidney. The resultant tumors and the majority of metastatic lesions within the lung and liver exhibited a mesenchymal-like phenotype. CONCLUSIONS/SIGNIFICANCE: Dormant DTCs within the bone marrow are highly malignant upon injection into the mammary fat pad, with the accelerated development of metastatic lesions within the lung, liver and kidney. These results suggest the acquisition of a more aggressive phenotype of DTCs during

    Full Text Available Abstract Background Loco-regionally advanced nasopharyngeal carcinomas can be cured by the combination of chemotherapy and radiotherapy. In Eastern countries, plasma levels of viral Epstein-Barr deoxyribonucleic acid (DNA are accurate in predicting recurrence, but few data are available in Western populations. The aim of this prospective study was to evaluate the relationship between viral Epstein-Barr DNA copy numbers in plasma and the response rate, progression-free survival and overall survival in a cohort of Western patients with stage IIb-IVb nasopharyngeal cancer. Methods We evaluated plasma samples from 36 consecutive patients treated with induction chemotherapy followed by chemoradiation. EBV copy numbers were determined after DNA extraction using real-time quantitative polymerase chain reaction. Survival curves were estimated using the Kaplan–Meier method. Results Circulating Epstein-Barr virus DNA levels were measured before treatment, at the end of concomitant chemo- and radiotherapy, and during the follow-up period. Pre-treatment levels significantly correlated with the initial stage and probability of relapse. Their increase was 100% specific and 71.3% sensitive in detecting loco-regional or metastatic recurrence (an overall accuracy of 94.4%. Three-year progression-free and overall survival were respectively 78.2% and 97.1%. Conclusions The results of this study confirm that patients from a Western country affected by loco-regionally advanced nasopharyngeal carcinoma have high plasma Epstein-Barr virus DNA levels at diagnosis. The monitoring of plasma levels is sensitive and highly specific in detecting disease recurrence and metastases.

    2012-11-01

    Full Text Available Abstract Background Overall survival of HER2 positive metastatic breast cancer patients has been significantly improved with inclusion of trastuzumab to chemotherapy. Several studies have demonstrated discordant HER2 status in the primary and metastatic tumour. However, rates of discordance vary considerably in published reports. Methods Information collected prospectively was analysed for all patients seen from 1999 to 2009 with primary breast cancer and who had biopsy of a local or distant recurrence. Patients were included if adequate tissue was available from both paired samples. Recurrent samples included fine needle aspirations, core and excisional biopsies. HER2 status in all paired samples was assessed by in-situ hybridisation by a single pathologist in a national reference laboratory. This was compared with HER2 immunohistochemistry results provided in the course of routine diagnosis at regional laboratories. Results In total, 157 patients with recurrent (n = 137; 87.3% or synchronous primary and metastatic (n = 20; 12.7% breast cancer had biopsy of the metastatic site. The study population comprised of 116 patients with adequate tissue in both primary and metastasis. The concordance between HER2 status of the paired samples by local immunohistochemistry testing and central in-situ hybridization were 78% and 99%, respectively. Only one patient demonstrated HER2 discordance – primary lesion was positive whilst a metastatic site was negative. Conclusions This single institution study demonstrated a low rate of HER2 discordance between primary and recurrent breast cancer as assessed by in-situ hybridisation. This contrasts to results reported by others, which may be explained by differences in study methodology, definition of recurrent disease samples and generally small numbers of patients assessed. Despite the current findings, the decision to obtain metastatic tissue for evaluation is influenced by other factors. These include disease

    Breast cancer is a prevalent disease and a major cause of morbidity and cancer-related deaths among women worldwide. A significant number of patients at the time of primary diagnosis present metastatic disease, at least to locoregional lymph nodes, which results in somewhat unpredictable prognosis that often prompts adjuvant systemic therapies of various kinds. The time course of distant recurrence is also unpredictable with some patients sustaining a recurrence within months after diagnosis,...

  12. Expression profiling of primary and metastatic ovarian tumors reveals differences indicative of aggressive disease.

    Directory of Open Access Journals (Sweden)

    Alexander S Brodsky

    Full Text Available The behavior and genetics of serous epithelial ovarian cancer (EOC metastasis, the form of the disease lethal to patients, is poorly understood. The unique properties of metastases are critical to understand to improve treatments of the disease that remains in patients after debulking surgery. We sought to identify the genetic and phenotypic landscape of metastatic progression of EOC to understand how metastases compare to primary tumors. DNA copy number and mRNA expression differences between matched primary human tumors and omental metastases, collected at the same time during debulking surgery before chemotherapy, were measured using microarrays. qPCR and immunohistochemistry validated findings. Pathway analysis of mRNA expression revealed metastatic cancer cells are more proliferative and less apoptotic than primary tumors, perhaps explaining the aggressive nature of these lesions. Most cases had copy number aberrations (CNAs that differed between primary and metastatic tumors, but we did not detect CNAs that are recurrent across cases. A six gene expression signature distinguishes primary from metastatic tumors and predicts overall survival in independent datasets. The genetic differences between primary and metastatic tumors, yet common expression changes, suggest that the major clone in metastases is not the same as in primary tumors, but the cancer cells adapt to the omentum similarly. Together, these data highlight how ovarian tumors develop into a distinct, more aggressive metastatic state that should be considered for therapy development.

    2010-01-01

    Full Text Available Ovarian cancer affects approximately 25,000 women in the United States each year and remains one of the most lethal female malignancies. A standard approach to therapy is surgical cytoreduction, after which the remaining microscopic residual disease is treated with chemotherapy. The vast majority of patients have disease recurrence, underscoring the crucial need for approaches to control the regrowth, or colonization, of tissues after local treatment. Improved therapies require mechanistic information about the process of metastatic colonization, the final step in metastasis, in which cancer cells undergo progressive growth at secondary sites. Studies of metastasis suppressors are providing insights into events controlling metastatic colonization. This paper reviews our laboratory's approach to the identification, characterization, and functional testing of the JNKK1/MKK4 metastasis suppressor in ovarian cancer metastatic colonization. Specifically, we demonstrate that interaction of ovarian caner cells with the omental microenvironment activates JNKK1/MKK4 resulting in decreased proliferation without affecting apoptosis. The potential role of the omental microenvironment, specifically milky spot structures, is also described. It is our goal to provide this work as a usable paradigm that will enable others to study metastasis suppressors in clinical and experimental ovarian cancer metastases.

  14. Age at diagnosis in women with non-metastatic breast cancer: Is it related to prognosis?

    International Nuclear Information System (INIS)

    Objective: Primary objective was to verify whether breast cancer patients aged less than 40 years at diagnosis have poorer prognosis than older patients. Secondary to assess prognostic factors influencing disease free survival. Methods: 941 women were diagnosed with non-metastatic breast cancer at NCI, Cairo in 2003. Epidemiologic, clinico-pathological characteristics, treatment modalities and disease free survival were compared among the two age groups. Prognostic factors were evaluated for association with disease-free survival. Results: One hundred-eighty-one patients (19.2%) were younger than 40 years and 760 (80.8%) were older. Older women presented with higher rates of comorbidities and younger women presented with more hormone non-responsive tumors. Young women presented with larger tumors pT4 = 13.8% compared to 8.6% in older women, yet not significant. Young women were treated with more conservative surgery, more adjuvant chemotherapy and radiotherapy while older women with more radical mastectomies and more hormonal treatment. Recurrence rates were significantly higher among young women 44,2% compared to 34.5% in older women. Five year disease free survival in young women was 38.9% ± 4.6% compared to 48.6% ± 2.5% with adjusted hazard ratio of 1.22 95% Cl (0.91-1.64),p = 0.19. Multivariate analyses identified positive axillary lymph nodes (pN2-pN3), larger tumor size (pT3-pT4), hypertension, lobular carcinoma type and lack of adjuvant systemic treatment as independent factors associated with poor DFS. Conclusion: Young women were not found to have poorer prognosis, yet they presented with more ER negative tumors. Most of women presented with advanced stage and young women had higher recurrence rates.

    Phyllode tumor (PT) is extremely rare tumor of the breast. Distant metastasis occurs in 10-20% of patients with malignant phyllode tumor. The most common sites of metastases are the lungs and bones. Although theoretically any organ may have metastasis, an isolated duodenum metastasis has not been documented as yet in the English-language literature. We report herein a case with a isolated duodenal metastasis from PT of breast in a 31 year-old-woman who underwent right mastectomy 4 years before because of the recurrent malignant PT. She presented to our hospital with massive upper gastrointestinal bleeding. Clinical evaluation revealed a huge mass originated from duodenum. Urgent laparotomy and pancreaticoduodenectomy were carried out in order to remove the bleeding duodenal mass.The pathologic examination of the resected specimen showed a malignant spindle cell tumor consistent with metastatic malignant PT. Our case of gastrointestinal bleeding due to an isolated duodenal metastasis as a result of hematogenous spread from malignant phyllode tumor of breast is unique in the English literature and pancreaticoduodenectomy is a curative treatment for patients with isolated duodenal involvement.

    Full Text Available ABSTRACT Objective: to evaluate the profile of morbidity and mortality and its predictors related to extensive pelvic resections, including pelvic exenteration, to optimize the selection of patients and achieve better surgical results. Methods: we performed 24 major resections for anorectal pelvic malignancy from 2008 to 2015 in the Instituto do Câncer do Ceará. The factors analyzed included age, weight loss, resected organs, total versus posterior exenteration, angiolymphatic and perineural invasion, lymph node metastasis and overall and disease-free survival. Results: the median age was 57 years and the mean follow-up was ten months. Overall morbidity was 45.8%, with five (20.8% serious complications. There were no deaths in the first 30 postoperative days. The median overall survival was 39.5 months, and disease-free survival, 30.7 months. Concomitant resection of the bladder was an isolated prognostic factor for higher risk of complications (87.5% vs. 26.7%, p = 0.009. Angiolymphatic invasion and lymph node metastasis did not reach significance with respect to disease-free survival. Conclusion: treatment of advanced anorectal tumors is challenging, often requiring combined resections, such as cystectomy and sacrectomy, and complex reconstructions. The magnitude of the operation still carries a high morbidity rate, but is a procedure considered safe and feasible, with a low mortality and adequate locoregional tumor control when performed in referral centers.

    A prospective randomized study was carried out to evaluate the effectiveness of MPA in the treatment of breast cancer by comparing low dose (600 mg/day) with high dose (1,200 mg/day) of MPA. In 35 evaluable cases, the response rate to treatment was 40.0% (8/20) with low dose MPA and 26.7% (4/15) with high dose MPA. There was no significant difference between the two groups. The serum MPA concentration measured by high-performance liquid chromatography (HPLC) assay was 23.2 +/- 17.6 ng/ml in the low-dose group and 89.5 +/- 56.7 ng/ml in the high-dose group. Intrapatient variability in serum MPA concentration was relatively stable, but interpatient variability was large. No correlation was found between the response rate and serum MPA concentration. The above results indicate that a low dose of MPA (600 mg/day) is a useful treatment with high effectiveness and safety in advanced and recurrent breast cancer patients. Though no exact data on the optimal serum concentration could not be obtained, it was obvious that a successful response cannot be expected from a serum MPA concentration of less than 17 ng/ml, which was the average serum concentration in NC and PD patients of the low-dose group.

    I-131 MIBG, a specific radiopharmaceutical agent for scintigraphic imaging and treatment of pheochromocytoma and neuroblastoma may be useful for detection of apudomas. Scintigraphy with I-123 radiolabeled MIBG was performed in a patient with metastatic carcinoid tumor from the rectum. I-123 MIBG scintigraphic findings showed multiple areas of abnormal tumor uptake of hepatic and bone metastases from the rectal carcinoid. Bone scintigraphy demonstrated multiple metastatic lesions. Computed tomography revealed multiple solid tumors of the liver. This report describes accumulation of I-123 MIBG in the liver and bone metastases from the rectal carcinoid. Radioiodine MIBG scintigraphy may be useful for detecting metastatic lesions, for evaluating postoperative recurrence, and also for the treatment of the carcinoid tumor. PMID:7788995

    We first compare the mathematical structure of quantum and classical mechanics when both are formulated in a C*-algebraic framework. By using finite von Neumann algebras, a quantum mechanical analogue of Liouville's theorem is then proposed. We proceed to study Poincare recurrence in C*-algebras by mimicking the measure theoretic setting. The results are interpreted as recurrence in quantum mechanics, similar to Poincare recurrence in classical mechanics.

    Objective: In order to study the clinical manifestation and risk factor of recurrent intracerebral hemorrhage(ICH).Methods:The 256 patients were analysed who admitted to our hospital for intracerebral hemorrhage between 1995 and 1997.The 15(5 .86%)patients had a recurrent ICH.There were 9 men and 6 women and the mean age of the patients was 63.5 ± 6.4years at the first bleeding episode and 67.8± 8. 5 years at the second. The mean interval between the two bleeding episodes was 44.6 ± 12.5 months. The 73.3%patients were hypertensive .′The site of the first hemorrhage was ganglionic in 8 patients , ]ohar in six paients and brainstem in one .The recurrent hemorrhage occurred at a different location from the previous ICH.The most common pattern of recurrence was “ganglionic -ganglionic” (7 patients), lobar - ganglionic (3 patients), lobar-lobar(three patients), which was always observed in hypertensive patients. The outcome after the recurrent hemorrhage was usually poor. By comparison with 24 patients followed up to average 47.5± 18.7 months with isolated ICH without recurrence .Only lobar hematoma and a younger age were risk factors for recurrences whereas sex and previous hypertension were not. The mechanism of recurrence of ICH were multiple(hypertension, cerebral amyloid angiopathy).Contral of blood pressure and good living habit after the first hemorrhage may prevent ICH recurrences.

    2015-01-01

    We optimally estimate the recurrence structure of a multivariate time series by Markov chains obtained from recurrence grammars. The goodness of fit is assessed with a utility function derived from the stochastic Markov transition matrix. It assumes a local maximum for the distance threshold of the optimal recurrence grammar. We validate our approach by means of the nonlinear Lorenz system and its linearized stochastic surrogates. Finally we apply our optimization procedure to the segmentation of neurophysiological time series obtained from anesthetized animals. We propose the number of optimal recurrence domains as a statistic for classifying an animals' state of consciousness.

    Alterations to drainage pathways in the head and neck as a result of surgical manipulation are not well understood. We present two unusual cases of oral squamous cell carcinoma metastatic to the level 6 nodal compartment following extensive treatment. Both oral squamous cell carcinoma cases exhibited metastases to the central neck compartment following extensive surgery and radiation. Each patient had prior history of multifocal oral cavity disease and recurrent neck metastases requiring salvage lymphadenectomy. Surgical interventions may alter the usual lymphatic drainage patterns. In cases of extensive treatment, all levels of the neck should be monitored for lymph node recurrence.

    Patients with progressive primary brain tumors (PBT) are attracted to promising new treatments, even prior to convincing data. Anti-PD1 immunotherapies have been in the spotlight since publication of groundbreaking results for metastatic melanoma with pembrolizumab (PBL). Our objective was to report on the response and toxicity of PBL in patients with advanced PBT. We retrospectively reviewed the charts of 22 patients (17 adults and 5 children) with recurrent central nervous system tumors treated with PBL. We analyzed prior antineoplastic therapies, steroid usage, and outcomes. Patients received a median of two neoplastic therapies prior to PBL, and a median of three infusions of PBL in adults and four in children. Twelve patients (9 adults and 3 children) started PBL on steroids (median dose in adults 4 mg; range 2-8, and in children 1.5 mg, range 0.5-4) and five patients received steroids later during PBL treatment. Twelve patients (10 adults and 2 children) received concomitant bevacizumab with PBL. Side effects were minimal. All patients showed progressive tumor growth during therapy. Median OS from the start of PBL was 2.6 months in adults and 3.2 months in children. Two GB patients underwent tumor resection following treatment with PBL. Tumor-lymphocytic response in these cases was unremarkable, and PD-L1 immuno-staining was negative. In this series of 22 patients with recurrent primary brain tumors, PBL showed no clinical or histologic efficacy. We do not recommend further use of PBL for recurrent PBT unless convincing prospective clinical trial data are published.

However, many aggressive cancers such as triple-negative breast cancer (TNBC currently lack well-defined therapeutic targets against which such agents can be developed. The identification of tumor-associated antigens and the generation of antibody drug-conjugates represent an emerging area of intense interest and growth in the field of cancer therapeutics. Glycoprotein non-metastatic b (GPNMB has recently been identified as a gene that is over-expressed in numerous cancers, including TNBC, and often correlates with the metastatic phenotype. In breast cancer, GPNMB expression in the tumor epithelium is associated with a reduction in disease-free and overall survival. Based on these findings, glembatumumab vedotin (CDX-011, an antibody-drug conjugate that selectively targets GPNMB, is currently being investigated in clinical trials for patients with metastatic breast cancer and unresectable melanoma. This review discusses the physiological and potential pathological roles of GPNMB in normal and cancer tissues, respectively, and details the clinical advances and challenges in targeting GPNMB-expressing malignancies.

    Full Text Available Background. Vinorelbine (VRB and capecitabine (CAPE are demonstrated to be active in pretreated metastatic breast cancer patients. Different studies have demonstrated that the metronomic treatment is active with an acceptable toxicity profile. We designed a Phases I-II study to define the MTD of oral metronomic, VRB, and CAPE. Patients and Methods. Phase I: fixed dose of CAPE was 500 mg thrice a day, continuously. Level I of VRB was 20 mg/tot thrice a week for 3 weeks (1 cycle. Subsequent levels were 30 mg/tot and 40 mg/tot (Level III, respectively, if no Grades 3-4 toxicity were observed in the previous level. Phase II: further 32 patients received the MTD of VRB plus CAPE for a total of 187 cycles to confirm toxicity profile. Results. 12 patients were enrolled in Phase I and 22 in Phase II. Phase I: the MTD of VRB was 40 mg. Phase II: 187 cycles were delivered, observing 5.9% of Grades 3-4 toxicity. 31 patients are evaluable for efficacy, obtaining a clinical benefit rate of 58.1%. Conclusion. MTD of VRB with fixed dose of CAPE was 40 mg thrice a week and was the recommended dose for the ongoing Phase II multicenter study.

    Full Text Available Colorectal cancer is one of the leading causes of cancer incidence and mortality. In 2008 inRussian Federation55 719 new cases of colorectal cancer were diagnosed and 37 911 patients died of this disease. A significant progress was achieved in metastatic colorectal cancer treatment during the last decades. A lot of treatment options became available: from 5-fluoruracil monotherapy to combined treatment treatment schemes including surgery. A group of patients with isolated liver metastases was distinguished, who can achieve 5-year survival rate of 40 % after systemic treatment and surgery. Today, based on clinical data and molecular analysis, we come close to individualized treatment of this patient group. In this literature review results of metastatic colorectal cancer chemotherapy are being analyzed and rational treatment tactic is proposed based on therapy goals.

    2015-03-01

    Treatment of advanced prostate cancer has changed considerably in recent years, but the vast majority of advances have been made in patients with metastatic castration-resistant disease. There have been relatively fewer advances in the earlier, hormonally responsive stage of metastatic disease. Since the empiric establishment of androgen deprivation therapy as first-line therapy for metastatic prostate cancer decades ago, there have been multiple studies looking at variations of suppressing testosterone, but the overall paradigm has not been strongly challenged until more recently. In particular, the dramatic results reported by the CHAARTED trial not only bring chemotherapy to an arena historically dominated solely by hormonal therapy but also stimulate renewed efforts into improving upon our management of metastatic hormone-sensitive prostate cancer.

    Full Text Available Perineal leiomyosarcoma is an extremely rare and aggressive cancer with a high metastatic potential and no defined standard treatment. There are only a few (six reported cases in the literature. We report the case of a 67-year-old woman with a perineal leiomyosarcoma arising at the same site of a previously resected superficial angiomyxoma. Initially, she was treated for a presumptive recurrence of angiomyxoma. As she did not respond to medical therapy, she underwent repeat surgical excision. Pathology revealed a high grade leiomyosarcoma, histologically strikingly distinct from the initial diagnosis. She received adjuvant local radiation therapy, and remains without evidence of recurrent disease 36 months after completion of all therapy. This is the first reported case of a high grade perineal leiomyosarcoma originating at the same site as a resected benign superficial angiomyxoma. Our case emphasizes the necessity of a prompt histological diagnosis in cases of presumed recurrent perineal angiomyxoma.

  2. Serum methionine metabolites are risk factors for metastatic prostate cancer progression.

    Directory of Open Access Journals (Sweden)

    Sally Stabler

    Full Text Available BACKGROUND: Clinical decision for primary treatment for prostate cancer is dictated by variables with insufficient specificity. Early detection of prostate cancer likely to develop rapid recurrence could support neo-adjuvant therapeutics and adjuvant options prior to frank biochemical recurrence. This study compared markers in serum and urine of patients with rapidly recurrent prostate cancer to recurrence-free patients after radical prostatectomy. Based on previous identification of urinary sarcosine as a metastatic marker, we tested whether methionine metabolites in urine and serum could serve as pre-surgical markers for aggressive disease. METHODOLOGY/PRINCIPAL FINDINGS: Urine and serum samples (n = 54 and 58, respectively, collected at the time of prostatectomy were divided into subjects who developed biochemical recurrence within 2 years and those who remained recurrence-free after 5 years. Multiple methionine metabolites were measured in urine and serum by GC-MS. The role of serum metabolites and clinical variables (biopsy Gleason grade, clinical stage, serum prostate specific antigen [PSA] on biochemical recurrence prediction were evaluated. Urinary sarcosine and cysteine levels were significantly higher (p = 0.03 and p = 0.007 respectively in the recurrent group. However, in serum, concentrations of homocysteine (p = 0.003, cystathionine (p = 0.007 and cysteine (p<0.001 were more abundant in the recurrent population. The inclusion of serum cysteine to a model with PSA and biopsy Gleason grade improved prediction over the clinical variables alone (p<0.001. CONCLUSIONS: Higher serum homocysteine, cystathionine, and cysteine concentrations independently predicted risk of early biochemical recurrence and aggressiveness of disease in a nested case control study. The methionine metabolites further supplemented known clinical variables to provide superior sensitivity and specificity in multivariable prediction models for

    2010-01-01

    Full Text Available We report a case of a female with stage I infiltrating ductal carcinoma who received adjuvant therapy including trastuzumab. One year later she developed lytic lesions and was retreated with trastuzumab that was held after she developed symptomatic heart failure. Lytic lesions were attributed to relapse of breast cancer, and cardiac failure attributed to prior trastuzumab therapy. After complications necessitated multiple hospitalizations, a further workup revealed that the lytic lesions were not metastatic breast cancer but multiple myeloma. Her advanced multiple myeloma was associated with systemic amyloidosis involving gut and heart, which ultimately led to her demise. This report addresses the pitfalls of overlapping symptoms and the question of which patients with suspected metastatic disease should undergo a biopsy.

    1991-08-01

    A total of 41 stereotactic interstitial brain implants in 39 patients were performed for recurrence after teletherapy (recurrence implant), or as part of initial treatment in conjunction with teletherapy (primary implant). Implanted tumors consisted of malignant gliomas (33), other primary brain tumors (3), and single metastatic lesions (3). All patients were temporarily implanted with Ir-192 using a coaxial catheter afterloading system; two patients were implanted twice. Survival post-implant for glioblastoma multiforme (GBM), 13 patients, was 10 months whether implanted primarily or for recurrence. Mean time to recurrence, measured from initiation of teletherapy to implantation, was 10 months. Twenty patients with anaplastic astrocytoma (AA) had a median survival post-implant of 23 months for primary implants (7 patients) and 11 months for recurrence implants (13 patients). Mean time to recurrence, measured from initiation of teletherapy to implantation, was 19 months. Three patients (9%) of the evaluable group required reoperation for symptomatic mass effect, all with initial diagnosis of AA. Survival for this subgroup was 14, 22, and 32 months post-implantation. Using stereotactic techniques, interstitial brachytherapy of brain tumors was technically feasible with negligible acute morbidity and mortality, and appeared to offer limited prolongation of control for a subset of patients with recurrent malignant gliomas. The role of this modality in primary treatment for malignant gliomas needs to be further defined by prospectively randomized trials.

    Adjuvant chemotherapy for breast cancer after surgery has effectively lowered metastatic recurrence rates. However, a considerable proportion of women suffer recurrent cancer at distant metastatic sites despite adjuvant treatment. Identification of the genes crucial for tumor response to specific...... of LAPTM4B resulted in sequestration of the anthracycline doxorubicin, delaying its appearance in the nucleus. Overexpression of these two genes was associated with poor tumor response to anthracycline treatment in a neoadjuvant chemotherapy trial in women with primary breast cancer.

    2013-01-01

    Two special Finsler spaces have been introduced and investigated, namely $R^h$-recurrent Finsler space and consircularly recurrent Finsler space. The defining properties of these spaces are formulated in terms of the first curvature tensor of Cartan connection. The following three results constitute the main object of the present paper: 1. A concircularly flat Finsler manifold is necessarily of constant curvature (Theorem A); 2. Every $R^h$-recurrent Finsler manifold is concirculaly recurrent with the same recurrence form (Theorem B); 3. Every horizontally integrable concircularly recurrent Finsler manifold is $R^h$-recurrent with the same recurrence form (Theorem C). The whole work is formulated in a coordinate-free form.

    2015-02-01

    Full Text Available Introduction: Sarcoidosis is an inflammatory disease characterized by non-caseating granulomas that can be present in diverse organ systems. Sarcoidosis can be associated with malignancy, presenting either preceding, during, or after chemotherapy. We herewith report a case of sarcoidosis mimicking cancer recurrence that developed after radioactive iodine therapy for papillary thyroid cancer. Background: A 68-year-old Caucasian woman was found to have an incidental mediastinal lymph node. She underwent biopsy, which revealed sarcoidosis. There was no further treatment or evidence of recurrence over the ensuing 9 years. She was then diagnosed with low-grade papillary thyroid cancer in the right posterior lobe and treated with total thyroidectomy followed by radioactive iodine therapy. Six months later, she was found to have elevated serum thyroglobulin. Post–remnant ablation scan showed increased tracer uptake in the bed of the thyroid. Though two thyroid ultrasound scans were negative, she was treated with I-131 for possible recurrence. She then developed right hip pain, prompting further investigation. Though a skeletal survey was negative, an 18-fluorodeoxyglucose positron emission tomography (PET scan study revealed multiple hypermetabolic skeletal lesions in both humeri and the proximal left femur. In addition, hypermetabolic hilar and mediastinal nodes were noted. As widespread cancer metastasis was suspected, bone biopsy was performed, which showed non-caseating granulomas, consistent with recurrence of sarcoidosis. Conclusion: Sarcoid lesions may mimic metastatic disease or recurrence in oncologic patients. Biopsy and histopathology examination should be performed to confirm the diagnosis. Recurrence or reactivation of sarcoidosis has been proposed to result from altered immunologic milieu because of the presence of either active cancer or its therapy. Teodorovic and colleagues postulated that the radioactive I-131 therapy leads to

    Full Text Available Abstract Introduction Soft tissue sarcomas are heterogeneous tumors that are difficult to treat. Up to 50 percent of patients develop metastatic disease and require systemic chemotherapy. Ifosfamide and doxorubicin are the two most active agents. Case presentation A 33-year-old Caucasian woman presented to our facility with a metastatic myxoid liposarcoma. Our patient was initially treated with surgery and radiation therapy, but experienced three recurrences during a six-year period, the first and the last occurring while our patient was pregnant. The first recurrence, which occurred two years after diagnosis and was localized in the left cervical and right axillary region, was treated with surgery followed by chemotherapy. Molecular analysis of this tumor showed a t(12,16 + translocation resulting in a FUS-DDIT3 or EWSR1-DDIT3 fusion. Three years later our patient experienced a second recurrence in the left supraclavicular fossa, upper thoracic and anterior mediastinum, which was treated with surgery alone. Eight months later, during the second pregnancy, our patient experienced a third recurrence as a large cervical mass that was treated, upon pregnancy, with trabectedin (1.5mg/m2/24-hour continuous infusion for a total of 12 cycles. At that time a computed tomography scan showed long-term partial response with excellent treatment tolerability. Conclusions This case report illustrates the potential therapeutic activity of trabectedin in patients with myxoid liposarcoma.

    The transitions from or to strange nonchaotic attractors are investigated by recurrence plot-based methods. The techniques used here take into account the recurrence times and the fact that trajectories on strange nonchaotic attractors (SNAs) synchronize. The performance of these techniques is shown for the Heagy-Hammel transition to SNAs and for the fractalization transition to SNAs for which other usual nonlinear analysis tools are not successful.

    Full Text Available Elahe A Mostaghel Division of Clinical Research, Fred Hutchinson Cancer Research Center, Seattle, WA, USA Abstract: Androgen deprivation therapy remains the single most effective treatment for the initial therapy of advanced prostate cancer, but is uniformly marked by progression to castration-resistant prostate cancer (CRPC. Residual tumor androgens and androgen axis activation are now recognized to play a prominent role in mediating CRPC progression. Despite suppression of circulating testosterone to castrate levels, castration does not eliminate androgens from the prostate tumor microenvironment and residual androgen levels are well within the range capable of activating the androgen receptor (AR and AR-mediated gene expression. Accordingly, therapeutic strategies that more effectively target production of intratumoral androgens are necessary. The introduction of abiraterone, a potent suppressor of cytochrome P450 17 α-hydroxysteroid dehydrogenase-mediated androgen production, has heralded a new era in the hormonal treatment of men with metastatic CRPC. Herein, the androgen and AR-mediated mechanisms that contribute to CRPC progression and establish cytochrome P450 17 α-hydroxysteroid dehydrogenase as a critical therapeutic target are briefly reviewed. The mechanism of action and pharmacokinetics of abiraterone are reviewed and its recently described activity against AR and 3-β-hydroxysteroid dehydrogenase is discussed. The Phase I and II data initially demonstrating the efficacy of abiraterone and Phase III data supporting its approval for patients with metastatic CRPC are reviewed. The safety and tolerability of abiraterone, including the incidence and management of side effects and potential drug interactions, are discussed. The current place of abiraterone in CRPC therapy is reviewed and early evidence regarding cross-resistance of abiraterone with taxane therapy, mechanisms of resistance to abiraterone, and observations of an

    Purpose/Objectives: Despite recent improvements in outcomes, 40% of children with high-risk neuroblastoma will experience relapse, facing a guarded prognosis for long-term cure. Whether recurrences are at new sites or sites of original disease may guide decision making during initial therapy. Methods and Materials: Eligible patients were retrospectively identified from institutional databases at first metastatic relapse of high-risk neuroblastoma. Included patients had disease involving metaiodobenzylguanidine (MIBG)-avid metastatic sites at diagnosis and first relapse, achieved a complete or partial response with no more than one residual MIBG-avid site before first relapse, and received no total body irradiation or therapy with {sup 131}I-MIBG before first relapse. Anatomically defined metastatic sites were tracked from diagnosis through first relapse to determine tendency of disease to recur at previously involved versus uninvolved sites and to assess whether this pattern was influenced by site irradiation. Results: Of 159 MIBG-avid metastatic sites identified among 43 patients at first relapse, 131 (82.4%) overlapped anatomically with the set of 525 sites present at diagnosis. This distribution was similar for bone sites, but patterns of relapse were more varied for the smaller subset of soft tissue metastases. Among all metastatic sites at diagnosis in our subsequently relapsed patient cohort, only 3 of 19 irradiated sites (15.8%) recurred as compared with 128 of 506 (25.3%) unirradiated sites. Conclusions: Metastatic bone relapse in neuroblastoma usually occurs at anatomic sites of previous disease. Metastatic sites identified at diagnosis that did not receive radiation during frontline therapy appeared to have a higher risk of involvement at first relapse relative to previously irradiated metastatic sites. These observations support the current paradigm of irradiating metastases that persist after induction chemotherapy in high-risk patients. Furthermore

    A case of metastatic papillary carcinoma to the mandible is presented. Though relatively rare, metastatic tumours of the mandible should be included in the differential diagnosis of the tumours in the parotid region. For the primary site; being in the cervicofacial region, the thyroid gland must be considered by the head and neck surgeon.

  3. CT of metastatic spinal tumor

    International Nuclear Information System (INIS)

    CT findings of metastatic spinal tumor were classified into 6 types, i.e., consolidation, dissolution, mottle, doughnut, and ring types, and mixed type of these, and that of no findings. Some statistically significant relationship was found between prostatic cancer and consolidation type, and unknown primary cancer and dissolution type. Abnormal findings of bone scintigraphy was suspected to have metastatic spinal tumor by plain radiography and CT scan in 64/128 (50.0%) and 113/145 (78.6%), respectively. There was some relationship between plain radiographic findings and CT findings; between consolidation type of the former and consolidation type of the latter, dissolution type and dissolution type, compression fracture type and mixed type, the type of no findings and consolidation or mixed type. The most of lesions detected by CT as consolidation or mixed type were revealed by plain radiography. Changes in Ca ammount was not detected by plain radiography and CT scan if it was approximately less than 30% and 18% of the initial Ca respectively. (Ueda, J.)

Surgery is the mainstay of treatment but there is no standard of care for locally advanced or metastatic disease. Hedgehog signaling proteins are critical for cell growth and differentiation during embryogenesis; Hh pathway is silenced in adults. Dysregulated or aberrant Hh signaling has been implicated in the pathogenesis of BCC. This hyperactive pathway can be inhibited by use of smoothened inhibitors such as vismodegib. Food and drug administration approved this oral, once-daily medication in 2012 to treat adults with metastatic BCC or locally advanced, recurrent BCC after surgery and also for patients with locally advanced BCC who are not candidates for surgery or radiation treatment. Clinical studies have shown it to be highly efficacious and the most common adverse effects include, muscle spasms, alopecia and dysgeusia. Use of targeted biologic modifiers, exemplified by Hh directed therapeutics offer a new hope to patients with high-surgical morbidity or inoperable tumors.

    Background: Salvage treatment for locally recurrent nasopharyngeal carcinoma (NPC) is complicated and relatively limited. Radiotherapy, combined with effective concomitant chemotherapy, may improve clinical treatment out‑comes. We conducted a phase II randomized controlled trial to evaluate the efcacy of intensity‑modulated radio‑therapy with concomitant weekly cisplatin on locally recurrent NPC. Methods: Between April 2002 and January 2008, 69 patients diagnosed with non‑metastatic locally recurrent NPC were randomly assigned to either concomitant chemoradiotherapy group (n = 34) or radiotherapy alone group(n= 35). All patients received intensity‑modulated radiotherapy. The radiotherapy dose for both groups was 60 Gy in 27 fractions for 37 days (range 23–53 days). The concomitant chemotherapy schedule was cisplatin 30 mg/m2 by intravenous infusion weekly during radiotherapy. Results: The median follow‑up period of all patients was 35 months (range 2–112 months). Between concomitant chemoradiotherapy and radiotherapy groups, there was only significant difference in the 3‑year and 5‑year overall survival (OS) rates (68.7% vs. 42.2%, P = 0.016 and 41.8% vs. 27.5%, P = 0.049, respectively). Subgroup analysis showedthat concomitant chemoradiotherapy significantly improved the 5‑year OS rate especially for patients in stage rT3–4 (33.0% vs. 13.2%, P = 0.009), stages III–IV (34.3% vs. 13.2%, P = 0.006), recurrence interval >30 months (49.0% vs. 20.6%,P= 0.017), and tumor volume >26 cm3 (37.6% vs. 0%, P = 0.006). Conclusion: Compared with radiotherapy alone, concomitant chemoradiotherapy can improve OS of the patients with locally recurrent NPC, especially those with advanced T category (rT3–4) and stage (III–IV) diseases, recurrence intervals >30 months, and tumor volume >26 cm3.

    Tamoxifen is now established for use in premenopausal as well as postmenopausal patients. Recent reports have not shown its activity to be enhanced by the addition of either prednisolone, progestogens, or interferon. Reversible ocular toxicity from tamoxifen appears to be more common than had been previously realized. Different schedules giving the same dose intensity of doxorubicin give markedly different pharmacokinetic profiles. Although this does not lead to differences in responses or physical toxicity, it seems to have important implications for quality of life. Taxol is showing impressive activity in advanced breast cancer, and significant response rates have also been reported for carboplatin and podophyllotoxin derivatives. To achieve maximum effectiveness from the cyclophosphamide, methotrexate, and fluorouracil combination, attention to schedule and dose intensity has been shown to be important. No new effective cytotoxic combinations have been described. High-dose chemotherapy requiring bone marrow support remains experimental. Further progress has been made in monitoring the response of metastatic bone disease to treatment. The precise significance for patients of the results in many of the papers reviewed is often uncertain because they lack quality-of-life measures; the importance of this approach is emphasized.

  8. Hyperhomocysteinemia in Recurrent Miscarriage

    International Nuclear Information System (INIS)

    Objective: An elevated total plasma homocysteine level has been suggested as a possible risk factor in women suffering from recurrent pregnancy loss. The current study was undertaken to assess the association between homocysteine, folate, cobalamin (vitamin B12) and the risk of recurrent pregnancy loss. Design: Case . control study Materials and Methods: The study included 57 non-pregnant Egyptian women. They were classified according to their obstetric history into 2 groups: 32 cases with at least two consecutive miscarriages (Study group), and 25 cases with normal obstetric history (Control group). All cases were tested for plasma total homocysteine, serum folate and cobalamin (vitamin B12). Results: The fasting total homocysteine was significantly higher in the study group as compared to the control group. While the median concentrations for the vitamins studied were significantly lower in women of the study group as compared to the controls. Elevated homocysteine and reduced vitamin B12 can be considered risk factors for recurrent miscarriage with odds ratio (OR) and 95% confidence intervals (95% CI) of 1.839 (1.286, 2.63) and 1.993 (1.346, 2.951) respectively in the group of recurrent miscarriages. The OR (95% CI) in the study population for low serum folate concentrations was 1.23 (0.776, 2.256). Conclusion: Elevated homocysteine and reduced serum vitamin B12 are risk factors for recurrent miscarriage. Low serum folate did not seem a risk factor for recurrent miscarriage. Testing for homocysteine levels in women suffering from unexplained recurrent miscarriage and pre-conceptional supplementation with vitamin B12 might be beneficial to improve pregnancy outcome

    Breast cancer that recurs as metastatic disease many years after primary tumor resection and adjuvant therapy seems to arise from tumor cells that disseminated early in the course of disease but did not develop into clinically apparent lesions. These long-term surviving, disseminated tumor cells maintain a state of dormancy, but may be triggered to proliferate through largely unknown factors. We now show that the induction of fibrosis, associated with deposition of type I collagen (Col-I) in the in vivo metastatic microenvironment, induces dormant D2.0R cells to form proliferative metastatic lesions through beta1-integrin signaling. In vitro studies using a three-dimensional culture system modeling dormancy showed that Col-I induces quiescent D2.0R cells to proliferate through beta1-integrin activation of SRC and focal adhesion kinase, leading to extracellular signal-regulated kinase (ERK)-dependent myosin light chain phosphorylation by myosin light chain kinase and actin stress fiber formation. Blocking beta1-integrin, Src, ERK, or myosin light chain kinase by short hairpin RNA or pharmacologic approaches inhibited Col-I-induced activation of this signaling cascade, cytoskeletal reorganization, and proliferation. These findings show that fibrosis with Col-I enrichment at the metastatic site may be a critical determinant of cytoskeletal reorganization in dormant tumor cells, leading to their transition from dormancy to metastatic growth. Thus, inhibiting Col-I production, its interaction with beta1-integrin, and downstream signaling of beta1-integrin may be important strategies for preventing or treating recurrent metastatic disease.

    Purpose: To identify the prognostic value of biological markers at initial operation for metastatic breast cancer, we measured the presence of estrogen receptor-alpha (ERα), progesterone receptor (PgR) and human epidermal growth factor receptor type 2 (HER2),and histological grade (HG) of tumors. Methods: One-hundred and seventy-six patients, aged 29 to 90 (median: 51 years), with recurrent breast cancer underwent primary operation at our department during the period from 1983 to 2000. Clinicopathological factors examined at primary operation included menopausal symptoms, presence of axillary lymph node metastasis, tumor size, HG, HER2, ERα and PgR.Factors examined at recurrence included site of primary recurrence, disease-free interval(DFI) and tumor markers, such as CEA and CA15-3. The relationship between these factors and prognosis following recurrence was assessed. Results: Menopausal status, axillary lymph node metastasis and tumor size at primary operation had no significant effect on prognosis. Patients with low HG, positive expession of ERα and PgR, and low HER2 expression had a good prognosis, similar to those with long DFI and distant metastases. After distant metastases, HER2 was found to be the most important prognostic factor following recurrence and in predicting response to drug therapy.Conclusion: Biological factors indicating tumor malignancy at the time of the first operation are also important prognostic factors following tumor recurrence.

    Full Text Available Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    Escherichia coli is the most common gram-negative organism associated with bacteremia. While recurrent E. coli urinary tract infections are well-described, recurrent E. coli bacteremia appears to be uncommon, with no episodes noted in multiple series of patients with gram-negative bacteremias. We report on 5 patients with recurrent bloodstream infections identified from a series of 163 patients with E. coli bacteremia. For each patient, the isolates from each episode were analyzed by pulsed-field gel electrophoresis (PFGE) and ribotyping and for the presence of E. coli virulence factors. For each of four patients, the index and recurrent episodes of bacteremia represented the same strain as defined by PFGE, and the strains were found to carry one or more virulence factors. The remaining patient, with two episodes of bloodstream infection separated by a 4-year interval, was infected with two isolates that did not carry any virulence factors and that were clonally related by ribotype analysis but differed by PFGE. All five patients had either a local host defense defect (three patients) or impaired systemic defenses (one patient) or both (one patient). Thus, recurrent E. coli bacteremia is likely to represent a multifactorial process that occurs in patients with impaired host defenses who are infected with virulent isolates. Images PMID:7910828

  15. PET-CT in the evaluation of metastatic breast cancer

    International Nuclear Information System (INIS)

    A 44-year-old woman underwent two PET-CT scans for the evaluation of metastatic breast cancer. A radical left mastectomy with axillary dissection (1 of 43 nodes positive) followed by chemotherapy, was performed in 1998. She represented in October 2003 with a left supraclavicular fossa mass. This was confirmed to be recurrent breast cancer on FNAB. She was considered for a radical neck dissection and the surgeon requested a PET scan. Other imaging at this time included a normal bone scan and CT brain. CT neck/chest/abdomen/pelvis showed soft tissue thickening in the left lower neck. The PET-CT scan showed multiple glucose avid lesions in the sternum, mediastinum and neck lymph nodes as well as a small lesion in the proximal left femur consistent with extensive metastatic disease. Surgery was cancelled and Femara chemotherapy commenced. Femara was stopped in March 2004 and the patient began alternative therapies. In October 2004 she presented to her surgeon with new back and chest pain. CT of the neck/chest/abdomen/pelvis showed a soft tissue mass in the upper sternum and a lymph node at the base of the neck highly suspicious for metastatic disease. There were also 2 suspicious lung nodules and a lesion in the proximal left femur reported as an osteoid osteoma. Wholebody PET-CT scans were performed on a Siemens LSO Biograph, 60mins after the injection of 350Mbq of Fl 8-Fag, with arms at the patient's side and head in the field-of-view. On both occasions the patient had to pay for the scan. On the 2004 PET-CT scan, the CT brain revealed multiple hyperdense lesions consistent with hemorrhagic metastases. In addition, there were innumerable glucose avid foci involving viscera, nodes and skeleton consistent with disseminated disease. Our case illustrates: (i) the value of PET in the management of metastatic breast cancer; (ii) the improved accuracy of PET-CT in delineating sites of disease; (iii) the issues of head movement in PET-CT and.

    In recent years, recurrent nova eruptions are often observed very intensely in wide range of wavelengths from radio to optical to X-rays. Here I present selected highlights from recent multi-wavelength observations. The enigma of T Pyx is at the heart of this paper. While our current understanding of CV and symbiotic star evolution can explain why certain subset of recurrent novae have high accretion rate, that of T Pyx must be greatly elevated compared to the evolutionary mean. At the same time, we have extensive data to be able to estimate how the nova envelope was ejected in T Pyx, and it turns to be a rather complex tale. One suspects that envelope ejection in recurrent and classical novae in general is more complicated than the textbook descriptions. At the end of the review, I will speculate that these two may be connected.

    Full Text Available Objective: Chordoma is a rare tumor with an unpredictable behaviour, and can display malignant behavior because of its tendency to local invasion and recurrence. We searched the prognostic value of histologic features, growth pattern, localization and Ki-67 proliferation index to predict disease-free survival.Material and Method: Twenty-nine cases diagnosed in a single center were included in the study and evaluated with their 81 surgical specimens, (29 primary tumors, 47 recurrent lesions and five metastatic foci regarding their matrix formation (myxoid, chondroid, cellular features, (pleomorphism, necrosis, inflammatory infiltration, patterns of proliferation (solid, trabecular, mixed and Ki-67 proliferation indices.Results: Eleven of the cases were females (37.9% while 18 of them were males (62.1% with a mean age of 54.1±14.6 (ranged between age 23-78 years. Thirty-eight percent of tumors were located in sacrococcigeal region followed by skull base and vertebrae (31% for both. Skull base chordomas which occured in younger patients (p=0.048 showed more trabecular pattern (p=0.04, chondroid matrix (p=0.063, lower Ki-67 (p=0.146 and longer disease-free survival (p=0.021. In contrast, tumors located in vertebrae, showed more “atypical” morphology with solid pattern, nuclear pleomorphism and dedifferentiation, higher Ki-67 indices and shorter disease-free survivals (p=0.021. Sacral tumors were the “intermediate group” which occurred in older patients, and demonstrated average Ki-67 proliferation indices and disease-free survivals.Conclusion: Vertebral localization, probably in relation with both histologic features and failure of surgery, appeared as a significant risk factor for recurrence and Ki-67 proliferation index retained its potential to predict disease-free survival.

    To assess the safety and availability of stereotactic radiotherapy (SRT) for metastatic brain tumors, we reviewed 54 consecutive cases with a total of 118 brain metastases treated with linear-accelerator-based stereotactic irradiation (STI). Nineteen patients with a total of 27 brain tumors that were larger than 3 cm or close to critical normal tissues were treated with SRT. The marginal dose of SRT was 15-21 Gy (median 21 Gy) in 3 fractions for 3 days. The median marginal dose of stereotactic radiosurgery (SRS) was 20 Gy. Effective rates of imaging studies were 72.7% and 94.4%, and those of clinical symptoms were 46.7% and 55.6% for SRT and SRS, respectively. One-year and two-year survival rates of SRT were 40.9% and 17.6%, respectively, and the median follow-up period was 6.4 months. The one-year survival rate of SRS was 32.7%, with a median follow-up of 4.6 months. Fourteen cases (7 cases each) had recurrent tumors at STI sites. Early complications were observed in one case of SRT and 8 cases of SRS, and late complications occurred in 3 cases of SRS. There were no significant differences among effective rates, survival rates, median follow-up times, recurrence rates, and complications between SRT and SRS. We concluded that SRT is a safe, effective therapy for large or eloquent area metastases. (author)

    Full Text Available A 56-year-old woman presented to our clinic for recurrent hypoglycemia after undergoing resection of an incidentally discovered nonfunctional pancreatic endocrine tumor 6 years ago. She underwent a distal pancreatectomy and splenectomy, after which she developed diabetes and was placed on an insulin pump. Pathology showed a pancreatic endocrine neoplasm with negative islet hormone immunostains. Two years later, computed tomography scan of the abdomen showed multiple liver lesions. Biopsy of a liver lesion showed a well-differentiated neuroendocrine neoplasm, consistent with pancreatic origin. Six years later, she presented to clinic with 1.5 years of recurrent hypoglycemia. Laboratory results showed elevated proinsulin, insulin levels, and c-peptide levels during a hypoglycemic episode. Computed tomography scan of the abdomen redemonstrated multiple liver lesions. Repeated transarterial catheter chemoembolization and microwave thermal ablation controlled hypoglycemia. The unusual features of interest of this case include the transformation of nonfunctioning pancreatic endocrine tumor to a metastatic insulinoma and the occurrence of atrial flutter after octreotide for treatment.

    Full Text Available Recurrent parotitis is an uncommon condition in children. Its etiological factors have not been proved till date although causes due to genetic inheritance, local autoimmune manifestation, allergy, viral infection and immunodeficiency have been suggested. The exact management of this disorder is not yet standardized, but a conservative approach is preferred and all affected children should be screened for Sjogren′s syndrome and immune deficiency including human immunodeficiency virus. We report a 12 years female child who presented with 12 episodes of non-painful recurrent swellings of the bilateral parotid gland in the past 3 years.

Metastatic carcinomas express reduced levels of IL-33 and diminished levels of antigen processing machinery (APM), compared to syngeneic primary tumours. Complementation of IL-33 expression in metastatic tumours upregulates APM expression and functionality of major histocompatibility complex (MHC)-molecules, resulting in reduced tumour growth rates and a lower frequency of circulating tumour cells. Parallel studies in humans demonstrate that low tumour expression of IL-33 is an immune biomarker associated with recurrent prostate and kidney renal clear cell carcinomas. Thus, IL-33 has a significant role in cancer immune-surveillance against primary tumours, which is lost during the metastatic transition that actuates immune escape in cancer. PMID:27619158

  2. Metastatic superscan on 99mTc-methylene diphosphonate bone scintigraphy in pediatric neuroblastoma

    International Nuclear Information System (INIS)

    Excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract on bone scintigraphy (BS) is known as a “superscan.” However the association of pediatric solid tumor malignancy with metastatic superscan has not been reported previously. We here describe two such cases of neuroblastoma who presented with metastatic superscan on 99mTc-methylene diphosphonate BS. Presence of a superscan usually indicates an advanced stage of the disease. The patient prognosis is usually poor. Though extremely rare superscan can be associated with pediatric solid tumor malignancies and should be kept in mind while reporting such cases

    Primary intracranial haemangiopericytomas (HPC) are rare, highly vascular tumours with a high propensity for local recurrence and distant metastasis. Optimal treatment includes maximal surgical resection followed by adjuvant radiotherapy. In 2007, new histopathological grading criteria were introduced to differentiate between high grade (World Health Organization [WHO] grade III) and low grade (WHO grade II) tumours. Given the rarity of this tumour, there is a paucity of information regarding the prognostic significance of histological grade. We conducted a retrospective review of our 20 year experience in treating 27 patients with HPC at our institution. Statistical analysis to compare overall survival, local recurrence rate and metastatic potential between the two grades were conducted using Kaplan-Meier analysis. The estimated median survival for grade II HPC was 216 months and for grade III tumours was 142 months. On multivariate analysis, grade II tumours were associated with better survival than grade III lesions (hazard ratio=0.16, 95% confidence interval 0.26-0.95; p=0.044). During the study period, 33% of grade III tumours developed local recurrence compared to 21% of grade II tumours. Metastases were found in 36% of grade II patients and 25% of grade III patients. There was no significant statistical difference in local recurrence rate and metastasis between the two grades. Higher histological grading in HPC is associated with worse overall survival. However based on our series higher histological grading is not associated with higher local recurrence or distant metastatic rates. PMID:24726230

    2007-01-01

    Metastatic melanoma to the common bile duct is very rare with only 18 cases reported so far. We report a 46 year old women who, 18 mo after excision of a skin melanoma, developped a painless progressive obstructive jaundice. At operation a melanoma within the distal third of the common bile duct was found. There were no other secondaries within the abdomen. The common bile duct, including the tumor, was resected and anastomosed with Roux-en-Y jejunal limb. The patient survived 31 mo without any sign of local recurrence and was submitted to three other operations for axillar and brain secondaries, from which she finally died. Radical resection of metastatic melanoma to the common bile duct may result in lifelong relief of obstructive jaundice.It is safe and relatively easy to perform. In other cases, a less aggressive approach, stenting or bypass procedures,should be adopted.

    Full Text Available Treatment of urachal adenocarcinoma (UA of the urinary bladder has typically been with radical cystectomy (RC but more conservative approaches are gaining popularity. Here we present the case of a female patient with metastatic primary bladder UA who was treated with robotic partial cystectomy (RPC and adjuvant chemotherapy; she is alive with no evidence of disease recurrence or metastatic disease at 5 years. This case provides some of the longest follow-up after RPC to date thereby demonstrating that RPC is a safe and oncologically viable treatment for selected patients even several years after definitive treatment. Patients undergoing RPC benefit from the reduced morbidity associated with this less radical treatment whilst enjoying similarly successful oncological outcomes to RC.

    BACKGROUND: Prostate cancer is a significant health problem in the United States and is the focus of increasing attention in our society. With the aging of the US population, it is likely that prostate cancer will continue to grow in importance. The options for systemic therapy of metastatic prostate cancer should be familiar to physicians, including nonspecialists, whose patients seek their advice and counsel. METHODS: Past and recent literature was surveyed to provide an understanding of the systemic treatment of advanced prostate cancer. The author presents a review of the systemic treatment of metastatic prostate cancer in different clinical circumstances and addresses the current status of chemotherapy in the management of advanced prostate cancer. RESULTS: Early androgen deprivation used over prolonged periods appears to be modestly superior to delayed androgen deprivation with a small potential survival advantage and an advantage in delaying disease progression in advanced prostate cancer. Patients with hormone-refractory prostate cancer may benefit from secondary hormonal therapy (eg, adrenal enzyme inhibitors, antiandrogens, glucocorticoids) and chemotherapy. CONCLUSIONS: The choices of therapy for metastatic prostate cancer depend on individual patient preference. Patients and physicians should be aware of the possible side effects associated with the therapeutics options for treatment of metastatic prostate cancer. PMID:10761100

    2016-01-01

    Advanced breast cancer frequently metastasizes to bone through a multistep process involving the detachment of cells from the primary tumor, their intravasation into the bloodstream, adhesion to the endothelium and extravasation into the bone, culminating with the establishment of a vicious cycle causing extensive bone lysis. In recent years, the crosstalk between tumor cells and secondary organs microenvironment is gaining much attention, being indicated as a crucial aspect in all metastatic steps. To investigate the complex interrelation between the tumor and the microenvironment, both in vitro and in vivo models have been exploited. In vitro models have some advantages over in vivo, mainly the possibility to thoroughly dissect in controlled conditions and with only human cells the cellular and molecular mechanisms underlying the metastatic progression. In this article we will review the main results deriving from in vitro co-culture models, describing mechanisms activated in the crosstalk between breast cancer and bone cells which drive the different metastatic steps.

  1. Potential synergistic implications for stromal-targeted radiopharmaceuticals in bone-metastatic prostate cancer

    2011-01-01

    Genetic heterogeneity and chemotherapy-resistant 'stem cells' represent two of the most pressing issues in devising new strategies for the treatment of advanced prostate cancer. Though curative strategies have long been present for men with localized disease, metastatic prostate cancer is currently incurable. Though substantial improvements in outcomes are now possible through the utilization of newly approved therapies, novel combinations are clearly needed. Herein we describe potentially synergistic interactions between bone stromal-targeted radiopharmaceuticals and other therapies for treatment of bone-metastatic prostate cancer. Radiation has long been known to synergize with cytotoxic chemotherapies and recent data also suggest the possibility of synergy when combining radiation and immune-based strategies. Combination therapies will be required to substantially improve survival for men with castrate-resistant metastatic prostate cancer and we hypothesize that bone-targeted radiopharmaceuticals will play an important role in this process.

    Full Text Available Purpose. We examined the impact of diabetes and hyperglycemia on cancer-specific survival of patients with metastatic or recurrent breast cancer (BC. Methods. We performed a retrospective analysis of 265 patients with advanced BC receiving palliative chemotherapy. BC-specific mortality was compared for diabetic and nondiabetic patients as well as for patients that presented hyperglycemia during treatment. Results. No difference was observed between the diabetic and nondiabetic patients in terms of overall survival (OS. A difference in OS was observed between nondiabetic patients and diabetic patients who had hyperglycemia. The OS was greater in diabetic patients with proper metabolic control than diabetic patients with hyperglycemia. The risk of death was higher in patients with mean glucose levels >130 mg/dL during treatment. Several factors were associated with poor OS: tumor stage, hormone-receptor-negative tumors, HER2 negative disease, multiple metastatic sites, presence of visceral metastases, and mean glucose >130 mg/dL. Conclusion. Elevated glucose levels are associated with a poor outcome in diabetic and nondiabetic patients in contrast to patients with normoglycemic levels, conferring an elevated risk of death. According to these results, clinicians should monitor glucose levels during treatment for advanced breast cancer disease and take action to maintain normal glucose levels.

    BRAF inhibitors have demonstrated improvement of overall survival in patients with metastatic melanoma and BRAF(V600) mutations. In order to evaluate BRAF tumor heterogeneity between primary and metastatic site, we have evaluated the performance of immunohistochemistry (IHC) with an anti-BRAF(V600E) antibody in both localization by comparison with high resolution melting analysis followed by Sanger sequencing in a parallel blinded study. A total of 230 samples distributed as primary melanoma (n = 88) and different types of metastatic samples (n = 142) were studied in 99 patients with advanced or metastatic melanoma (stage III or IV). The prevalence of each BRAF mutation was c.1799T>A, BRAF(V600E) (45.2%), c.1799_1800TG>AA, BRAF(V600E2) (3.0%), c.1798_1799GT>AA, BRAF(V600K) (3.0%), c.1801 A>G, BRAF(K601E) (1.3%), c.1789_1790CT>TC, BRAF(L597S) (0.4%), c.1780G>A, BRAF(D594N) (0.9%) respectively. IHC was positive in 109/112 samples harboring BRAF(V600E/E2) mutations and negative in other cases. The cytoplasmic staining was either strongly positive in tumor cells of BRAF(V600E) mutated cases. It appeared strong brown, different from the vesicular grey cytoplasmic pigmentation of melanophages. Concordance between the two techniques was 96.4%. Sensitivity of IHC for detecting the BRAF(V600E/E2) mutations was 97.3%, while specificity was 100%. Both our IHC and molecular study demonstrated homogeneity between primary and metastatic sites for BRAF status in melanoma. This study also provides evidence that IHC may be a cost-effective first-line method for BRAF(V600E) detection. Thereafter, molecular techniques should be used in negative, ambiguous or non-contributive cases.

    Full Text Available Chemoradiotherapy is increasingly used in advanced laryngeal cancers. Failures are generally managed by surgery. They include histologically confirmed recurrent or residual disease or a symptomatic life threatening treatment sequelae. Tumour recurrence or residivism can be managed by chemotherapy when radical surgery is either refused by the patient or if the general condition of the patient do not permit it. However surgery becomes inevitable when life threatening treatment sequelae like absolute pharyngo-oesophageal stricture and aspiration sets in.

    AIM: To assess the clinical role of monoclonal immunoscintigraphy for the detection of metastasis and recurrence of colorectal cancer. METHODS: Monoclonal immunoscintigraphy was performed in patients operated on for colorectal adenocarcinomasuspected of local recurrence and metastatic disease. The results were compared with conventional diagnostics. RESULTS: Immunoscintigraphic investigation was done in 53 patients. Tumor recurrence occurred in 38 patients, and was confirmed by other diagnostic modalities in 35. In 15 patients, immunoscintigraphic findings were negative, and confirmed in 14 with other diagnostic methods. Comparative analysis confirmed good correlation of immunoscintigraphic findings and the results of conventional diagnostics and the level of tumor marker carcinoembryonic antigen. Statistical analysis of parameters of radiopharmaceutical groups imacis, indimacis and oncoscint presented homogenous characteristics all of three radiopharmaceuticals. The analysis of immunoscintigraphic target focus was clearly improved using tomography. CONCLUSION: Immunoscintigraphy is highly specific and has a good predictive value in local recurrence of colorectal cancer.

    Full Text Available In the past ten years we have made exceptional progresses in the understanding of RCC biology, particularly by recognizing the crucial pathogenetic role of activation of the HIF/VEGF and mTOR pathways. This has resulted in the successful clinical development of anti-angiogenic and mTOR-targeted drugs, which have profoundly impacted on the natural history of the disease and have improved the duration and quality of RCC patient lives. However, further improvements are still greatly needed: 1 even in patients who obtain striking clinical responses early in the course of treatment, disease will ultimately escape control and progress to a treatment-resistant state, leading to therapeutic failure; 2 prolonged disease control usually requires 'continuous' treatment, even across different treatment lines, making the impact of chronic, low-grade, toxicities on quality of life greater and precluding, for most patients, the possibility of experiencing 'drug-free holidays'; 3 although we have successfully identified classes of drugs (or molecular mechanisms of action that are effective in a substantial proportion of patients, we still fall short of molecular predictive factors that identify individual patients who will (or will not benefit from a specific intervention and still proceed on a trial-and-error basis, far from a truly 'personalized' therapeutic approach; 4 finally (and perhaps most importantly, even in the best case scenario, currently available treatments inevitably fail to definitively 'cure' metastatic RCC patients. In this review we briefly summarize recent developments in the understanding of the molecular pathogenesis of RCC, the development of resistance/escape mechanisms, the rationale for sequencing agents with different mechanisms of action, and the importance of host-related factors.

    Full Text Available Background: Desmoid tumors are rare neoplasms of uncertain etiology arising from fascial or deep musculoaponeurotic structures. Although with benign histological appearance and no metastatic potential, desmoid tumors are locally aggressive tumors with a high rate of local recurrence. Case Report: The case of a 47 years old woman repeatedly operated for a recurrent desmoid tumor of the right thigh is presented. The initial radical excision was followed by adjuvant radiotherapy but local recurrence was diagnosed one year after. The pathology report revealed aspects of desmoid tumor. The patient was reoperated and subsequently referred for chemo- and hormonal therapy. A second recurrence occurred 20 months later and the patient was again operated with microscopic tumor free margins and positive long term outcome. Conclusion: Desmoid tumors are benign tumors with unpredictable natural history. Best management involves a multidisciplinary approach. Concerning diagnosis, the best approach is performing a MRI examination. Wide surgical resection with adjuvant radiation therapy remains the main treatment option for local control.

    A reliable detection of metastatic risk factors is important for children with retinoblastoma to choose the right therapeutic regimen. First studies using high-resolution magnetic resonance imaging (MRI) with orbit surface coils were promising. The aim of this study was therefore to evaluate the ability of high-resolution MRI to detect metastatic and especially advanced metastatic risk factors in a large group of children with retinoblastoma. One hundred forty-three consecutive children with retinoblastoma (148 enucleated eyes, 64 girls, 79 boys, mean age 19.7 ± 15.3) who received pretherapeutical high-resolution MRI with orbit surface coils on 1.5 T MR scanner systems between 2007 and 2012 and subsequent primary enucleation within 14 days were included in this retrospective study. Image analysis was performed by two neuroradiologists experienced in ocular imaging in consensus. Histopathology served as gold standard. Sensitivity/specificity for the detection of metastatic risk factors using high-resolution MRI with orbit surface coils were 60 %/88.7 % for postlaminar optic nerve infiltration, 65.5 %/95.6 % for choroidal invasion, 100 %/99.3 % for scleral invasion, and 100 %/100 % for peribulbar fat invasion, respectively. The results increased for the detection of advanced metastatic risk factors, 81.8 %/89.1 % for deep postlaminar optic nerve infiltration, 70.6 %/97.6 % for massive choroidal invasion. High-resolution MRI is clinically valuable for the detection of metastatic, especially of advanced metastatic risk factors in children with retinoblastoma. (orig.)

    Cancer cells with stem or progenitor properties play a pivotal role in the initiation, recurrence and metastatic potential of solid tumors, including those of the human prostate. Cancer stem cells are generally more resistant to conventional therapies thus requiring the characterization of key pathways involved in the formation and/or maintenance of this malignant cellular subpopulation. To this end, we identified Glycogen Synthase Kinase-3β (GSK-3β) as a crucial kinase for the maintenance of prostate cancer stem/progenitor-like cells and pharmacologic inhibition of GSK-3β dramatically decreased the size of this cellular subpopulation. This was paralleled by impaired clonogenicity, decreased migratory potential and dramatic morphological changes. In line with our in vitro observations, treatment with a GSK-3β inhibitor leads to a complete loss of tumorigenicity and a decrease in metastatic potential in preclinical in vivo models. These observed anti-tumor effects appear to be largely Wnt-independent as simultaneous Wnt inhibition does not reverse the observed antitumor effects of GSK-3β blockage. We found that GSK-3β activity is linked to cytoskeletal protein F-actin and inhibition of GSK-3β leads to disturbance of F-actin polymerization. This may underlie the dramatic effects of GSK-3β inhibition on prostate cancer migration. Furthermore, GSK-3β inhibition led to strongly decreased expression of several integrin types including the cancer stem cell-associated α2β1 integrin. Taken together, our mechanistic observations highlight the importance of GSK-3β activity in prostate cancer stemness and may facilitate the development of novel therapy for advanced prostate cancer.

    Full Text Available Recurrent and chronic infections in children are one of the most common reasons for physicians' visits that make a diagnostic challenge to pediatricians. Although the majority of referred  children  with  recurrent  infections  are  normal,  underlying causes  of  recurrent infection  such  as  atopy,  anatomical and  functional  defects,  and  primary or  secondary immunodeficiency must be considered in evaluation of children with this complaint.Although primary immunodeficiency diseases (PIDs were originally felt to be rare, it has became clear that  they are much  more  common  than  routinely appreciated. Early and accurate detection  of  PIDs  in children is essential to  institute  early lifesaving care and optimized treatments.Therefore in the approach to children with recurrent infections, careful medical history taking and physical examination with more attention to warning PIDs signs and symptoms are essential to distinguish those children with underlying PIDs from those who are normal or having other underlying disorders. If indicated, appropriate laboratory studies including simple screening and advanced tests must be performed.

    Full Text Available The purpose was to develop a metastatic score specific to the hepatic and peritoneal site in colorectal cancer patients from clinical, pathohistological and molecular markers potentially reflecting oncogenic activation (OA or epithelial-mesenchymal transition (EMT, where OA may reflect an activation and EMT the functional loss of certain genes. The primary tumour stage (OA, EMT, lymphonodal stage (OA, the presence of a lymphangiosis carcinomatosa (OA, histological grade (OA, EMT, and immunoblot extraction of E-cadherin (OA, EMT were differentially rated with zero to one or two points due to their potential contribution to each process and the resulting scores were validated in 27 colorectal cancer patients (three patients with pre-malignant adenomas, 16 with primaries and two with local recurrencies, three of which were metastatic to the peritoneum, six metastatic to the liver and two metastatic to both, the liver and the peritoneum, and five with hepatic secondaries, one of which at histology was metastatic to the peritoneum too. As a single parameter only the N-stage significantly contributed to OA (p<0.05. Median OA and EMT scores, however, were 3.5 and 2 in the case of primaries without further spread, 5 and 4 in those nodal positive, 5 and 4 in the case of peritoneal implants, 6 and 2 in the case of liver metastases, and 6.5 and 3 in the case of a simultaneous hepatic and peritoneal spread, respectively. These differences were significant when scores from patients with and without liver metastases (OA, p<0.002 or with peritoneal implants and isolated hepatic spread (EMT, p<0.01 were compared. The results suggest a site-specific contribution of OA and EMT to tumour progression in human colon cancer.

    Full Text Available Background: High grade metastatic spinal tumors are most common and are invasive. These patients can succumb to disease progression if not treated timely. Although considered as invasive and morbid, total enbloc spondylectomy (TES in selected cases has better survival rates. The authors describe the results of TES for high grade metastatic spinal tumors. Materials and Methods: Five patients (four females and one male underwent TES for solitary metastatic vertebral lesion between November 2012 and January 2014. These patients presented to us with spinal instability, unrelenting severe spinal pain and/or with severe progressive radiculopathy. Average age was 46.2 years (range 39-62 years. After complete investigations, computed tomography scan, magnetic resonance imaging scan and positron emission tomography (PET scan, it was confirmed that these patients had high grade solitary vertebral metastatic tumor. Results: Average duration of followup was 18 months (range 16-20 months. The average preoperative visual analog scale score of 9.4 (range 9-10 improved to 2 (range 1-4 at last followup. Average blood loss was 1440 mL (range1000-2000 mL. Average duration of surgery was 198 min (range180-240 min. Significant pain relief was noticed in each patient in the immediate postoperative period and during followups. These patients attained complete functional activities of daily living with in a month. The imaging showed implants in situ, no recurrence of tumor, and no activity on PET scan at the final followup. Conclusion: The present series shows favorable short term results of TES for solitary, metastatic, high grade vertebral body tumors by a team approach.

    Parosteal osteosarcoma (POS) is conventionally a low-grade sarcoma with limited metastatic potential; however, the tumor occasionally transforms into a high-grade dedifferentiated POS, which commonly metastasizes to distant organs. The present report describes a rare pediatric case of conventional POS with no dedifferentiated component yet had multiple pulmonary metastases at initial diagnosis. Following limb-sparing surgery and osteosarcoma-oriented neoadjuvant chemotherapy, the patient received total resection of pulmonary metastases. Despite no treatment for pulmonary recurrence 1 year after adjuvant chemotherapy, the patient is alive with stable disease 4 years and 6 months after the initial diagnosis. PMID:27149276

    The prostate cancer in its hormone-sensitive metastatic presentation is infrequent, it is either an initial presentation of the disease or an evolution after local treatment, without castration of the biological relapse. The surgical or biological castration remains the cornerstone of the treatment. The deadline of castration initiation and its modalities of administration, intermittent or continuous rest debated but consensual on the initiation is the appearance of the symptomatic disease. The chemotherapy by docetaxel in association with the castration increases significantly the survival of the patients having a high tumoral volume. The efficacy on the whole metastatic population requires additional analyses. Clinical prognostic factors as the bone localizations (axial or appendicular), the visceral involvement (liver, lung) are determining for the survival of these patients. Biological prognostic factors are in evaluation. Except the clodronate acid, which showed a survival improvement in the hormone-sensitive metastatic prostate cancer (HSMPC), the other treatments targeting the bone (zoledronic acid, rank-ligand inhibitor) demonstrated a benefit only in castrate resistant metastatic prostate cancer (MCRPC). The management of local disease lets suggest a benefit to at least symptomatic disease, but it requires to be estimated prospectively in clinical trials. The new hormonal treatments targeting the androgen receptor in CPMRC are in evaluation in CPMHS. The objective is to increase the survival and the quality of life of the CPMHS and to delay the evolution towards the castration resistant metastatic disease. PMID:25609491

    2013-01-01

    Insulinoma is a rare pancreatic neuroendocrine tumor. Overproduction of insulin and associated hypoglycemia are hallmark features of this disease. Diagnosis can be made through demonstration of hypoglycemia and elevated plasma levels of insulin or C-Peptide. Metastatic disease can be detected through computerized tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET)/CT. Somatostatin receptor scintigraphy can be used not only to document metastatic disease but also as a predictive marker of the benefit from therapy with radiolabeled somatostatin analog. Unresectable metastatic insulinomas may present as a major therapeutic challenge for the treating physician. When feasible, resection is the mainstay of treatment. Prevention of hypoglycemia is a crucial goal of therapy for unresectable/metastatic tumors. Diazoxide, hydrochlorothiazide, glucagon, and intravenous glucose infusions have been used for glycemic control yielding temporary and inconsistent results. Sandostatin and its long-acting depot forms have occasionally been used in the treatment of Octreoscan-positive insulinomas. Herein, we report a case of metastatic insulinoma with very difficult glycemic control successfully treated with the radiolabeled somatostatin analog lutetium (177LU). PMID:24455330

  11. Metastatic neoplasms of the central nervous system

    International Nuclear Information System (INIS)

    Metastatic neoplasms to the central nervous system are often encountered in the practice of surgical neuropathology. It is not uncommon for patients with systemic malignancies to present to medical attention because of symptoms from a brain metastasis and for the tissue samples procured from these lesions to represent the first tissue available to study a malignancy from an unknown primary. In general surgical pathology, the evaluation of a metastatic neoplasm of unknown primary is a very complicated process, requiring knowledge of numerous different tumor types, reagents, and staining patterns. The past few years, however, have seen a remarkable refinement in the immunohistochemical tools at our disposal that now empower neuropathologists to take an active role in defining the relatively limited subset of neoplasms that commonly metastasize to the central nervous system. This information can direct imaging studies to find the primary tumor in a patient with an unknown primary, clarify the likely primary site of origin in patients who have small tumors in multiple sites without an obvious primary lesion, or establish lesions as late metastases of remote malignancies. Furthermore, specific treatments can begin and additional invasive procedures may be prevented if the neuropathologic evaluation of metastatic neoplasms provides information beyond the traditional diagnosis of ''metastatic neoplasm.'' In this review, differential cytokeratins, adjuvant markers, and organ-specific antibodies are described and the immunohistochemical signatures of metastatic neoplasms that are commonly seen by neuropathologists are discussed

    2015-11-01

    Metastasis is the process by which cells from a primary tumor disperse and form new tumors at distant anatomical locations. The treatment and prevention of metastatic cancer remains an extremely challenging problem. This work introduces a novel biologically motivated objective function to the radiation optimization community that takes into account metastatic risk instead of the status of the primary tumor. In this work, we consider the problem of developing fractionated irradiation schedules that minimize production of metastatic cancer cells while keeping normal tissue damage below an acceptable level. A dynamic programming framework is utilized to determine the optimal fractionation scheme. We evaluated our approach on a breast cancer case using the heart and the lung as organs-at-risk (OAR). For small tumor α /β values, hypo-fractionated schedules were optimal, which is consistent with standard models. However, for relatively larger α /β values, we found the type of schedule depended on various parameters such as the time when metastatic risk was evaluated, the α /β values of the OARs, and the normal tissue sparing factors. Interestingly, in contrast to standard models, hypo-fractionated and semi-hypo-fractionated schedules (large initial doses with doses tapering off with time) were suggested even with large tumor α/β values. Numerical results indicate the potential for significant reduction in metastatic risk.

  13. Recurrent cerebral thrombosis

    International Nuclear Information System (INIS)

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

    Background Multidetector computed tomography (MDCT) is widely accepted as an effective imaging modality in monitoring for bladder cancer recurrence after radical cystectomy. Elucidating the pattern of bladder cancer recurrence on CT can increase the diagnostic accuracy. Purpose To evaluate the recurrence patterns of transitional cell carcinoma of the bladder and the factors associated with cancer recurrence. Material and Methods One hundred and forty-nine consecutive patients (mean age, 66.55 years; range, 32-86 years) who underwent preoperative contrast-enhanced CT and radical cystectomy were included in this study. The presence, site, and time of tumor recurrence were recorded retrospectively by two radiologists in a consensus fashion. The association of tumor recurrence and tumor factors (T stage, lymph node metastasis, nuclear grade, and tumor diameter) were also evaluated using multiple logistic regression analysis and Kaplan-Meier statistics. Results Tumor recurrence occurred in 60 patients (40.3%) with a mean time of 14 months (range, 1-64 months). The sites of recurrence included the operation site (n = 20), lymph node (n = 20), bone (n = 11), liver (n = 6), lung (n = 5), upper urinary tract (n = 4), colon (n = 3), adrenal gland (n = 2), peritoneum (n = 1), abdominal wall (n = 1), psoas muscle (n = 1), and penile skin (n = 1). Tumor recurrence was found to be associated with advanced T stage (P = 0.002) and lymph node metastasis (P < 0.001). Conclusion Transitional cell carcinomas of the bladder recur more frequently at the operation site and lymph node, and T-stage and lymph node metastasis are closely associated with tumor recurrence.

    Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

    2012-06-01

    Recurrent respiratory papillomatosis (RRP) is a rare, benign disease with no known cure. RRP is caused by infection of the upper aerodigestive tract with the human papillomavirus (HPV). Passage through the birth canal is thought to be the initial transmission event, but infection may occur in utero. HPV vaccines have helped to provide protection from cervical cancer; however, their role in the prevention of RRP is undetermined. Clinical presentation of initial symptoms of RRP may be subtle. RRP course varies, and current management focuses on surgical debulking of papillomatous lesions with or without concurrent adjuvant therapy. PMID:22588043

    Metastatic pulmonary calcification is a condition of calcium deposition in the normal pulmonary parenchyma, and this is secondary to abnormal calcium metabolism without any prior soft tissue damage. The predisposing factors for this condition include chronic renal failure, hypercalcemia and increased tissue alkalinity. The most common radiologic manifestation consists of poorly defined nodular opacities in the upper lung zone. These opacities reflect the deposition of calcium salts in the pulmonary interstitium. We present here a case of metastatic pulmonary calcification in a patient who recovered from pneumonia with sepsis and whose high-resolution CT (HRCT) images demonstrated localized parenchymal airspace calcification that was limited to the bilateral lower lobes. These lower lobes had been involved with pneumonic consolidation without calcification, as seen on the previous CT scan. In summary, we report here on an atypical presentation of metastatic pulmonary calcification that showed dense airspace consolidation localized to the bilateral lower lobes in a patient with primary hyperparathyroidism and pneumonia.

    Objectives. To evaluate the effect of surgical treatment on metastatic spinal tumor. Methods. The results of surgical intervention for metastatic spinal tumor of 31 consecutive patients since October 1985 were reviewed. Results. The average survival time was 17.6 months (range from 3 months to 9 years), and 4 patients are still alive with an average survival time of 24.6 months (range, 14~ 84 months). No postoperative complication was noted. The preoperative symptoms were partially relieved and neurological functions were improved after surgery. Conclusions. Surgical treatment for metastatic spinal tumor could improve the life quality, but should be adopted cautiously. The surgical procedures such as decompression and internal fixation should be involved only when neurological deficits occurred. The surgery with postoperative complementary therapy may not only improve the life quality , but also extend the patients' life span.

    Full Text Available Abstract Background A better understanding of the development of metastatic disease and the identification of molecular markers for cancer spread would be useful for the design of improved treatment strategies. This study was conducted to identify gene expressions associated with metastatic phenotypes of locally advanced cervical carcinomas and investigate whether gains or losses of these genes could play a role in regulation of the transcripts. Gene expressions and copy number changes were determined in primary tumors from 29 patients with and 19 without diagnosed lymph node metastases by use of cDNA and genomic microarray techniques, respectively. Results Thirty-one genes that differed in expression between the node positive and negative tumors were identified. Expressions of eight of these genes (MRPL11, CKS2, PDK2, MRPS23, MSN, TBX3, KLF3, LSM3 correlated with progression free survival in univariate analysis and were therefore more strongly associated with metastatic phenotypes than the others. Immunohistochemistry data of CKS2 and MSN showed similar relationships to survival. The prognostic genes clustered into two groups, suggesting two major metastatic phenotypes. One group was associated with rapid proliferation, oxidative phosphorylation, invasiveness, and tumor size (MRPS23, MRPL11, CKS2, LSM3, TBX3, MSN and another with hypoxia tolerance, anaerobic metabolism, and high lactate content (PDK2, KLF3. Multivariate analysis identified tumor volume and PDK2 expression as independent prognostic variables. Gene copy number changes of the differentially expressed genes were not frequent, but correlated with the expression level for seven genes, including MRPS23, MSN, and LSM3. Conclusion Gene expressions associated with known metastatic phenotypes of cervical cancers were identified. Our findings may indicate molecular mechanisms underlying development of these phenotypes and be useful as markers of cancer spread. Gains or losses of the genes

Lanzara”, Seconda Università degli Studi di Napoli, Napoli, Italy; 2Dipartimento di Endocrinologia ed Oncologia Molecolare e Clinina, Università di Napoli Federico II, Napoli, ItalyIntroduction: Colorectal cancer is the fourth most common malignant disease. Of newly diagnosed patients, 40% have metastatic disease at diagnosis, and approximately 25% of patients with localized disease at diagnosis will ultimately develop metastatic disease. The benefits of systemic chemotherapy in the treatment of metastatic colorectal cancer over best supportive care have been established. Panitumumab (ABX-EGF is the first fully human monoclonal antibody developed for use in colorectal cancer that targets the extracellular domains of epidermal growth factor receptor.Aims: The goal of this article is to review the published evidence for the use of panitumumab in the treatment of metastatic colorectal cancer to define its therapeutic potential.Evidence review: The major evidence of panitumumab activity in colorectal cancer has appeared in meeting report abstracts. One phase II study in monotherapy, one in combination with chemotherapy, and one phase III study have included only patients with metastatic colorectal cancer.Clinical potential: To date, in phase II clinical studies panitumumab has demonstrated antitumor activity in advanced, refractory colorectal cancer. As monotherapy it resulted in a 10% response rate with 38% of patients having stable disease, and a 36% response rate with 46% stable disease when combined with chemotherapy. A phase III study indicates a clinically significant advantage of panitumumab as third-line monotherapy over best supportive care. Panitumumab appears to have a good tolerability profile, with no maximum tolerated

    We describe a case of cavitary metastasis to the lungs from a small angiosarcoma of the scalp, in which the metastatic lesions were complicated by pneumothorax and pulmonary hemorrhage. On high-resolution CT, the lesions simulated the findings of Langerhans cell histiocytosis. Thin-walled cavitary metastatic lesions were similar to those of thin walled air cysts in Langerhans cell histiocytosis. Ground-glass opacity simulated the findings of smoker's respiratory bronchiolitis in Langerhans cell histiocytosis but histologically represented hemorrhage during metastasis of the angiosarcoma.

    Primary renal leiomyosarcomas are rare, aggressive tumors. They constitute 1-2% of adult malignant renal tumors. Although leiomyosarcomas are the most common histological type (50-60%) of renal sarcomas, information on renal leiomyosarcoma is limited. Local or systemic recurrences are common. The radiological appearance of renal leiomyosarcomas is not specific, therefore renal leiomyosarcoma cannot be distinguished from renal cell carcinoma by imaging methods in all patients. A 74-year-old female patient presented to our clinic complaining of a palpable mass on the right side of her abdomen in November 2012. The abdominal magnetic resonance imaging revealed a mass, 25 × 24 × 23 cm in size. Her past medical history revealed that she has undergone right radical nephrectomy in 2007, due to a 11 × 12 × 13 cm renal mass that was then reported as renal cell carcinoma on abdominal magnetic resonance imaging, but the pathological diagnosis was low-grade renal leiomyosarcoma. The most recent follow-up of the patient was in 2011, with no signs of local recurrence or distant metastases within this four-year period. The patient underwent laparotomy on November 2012, and a 35 cm retroperitoneal mass was excised. The pathological examination of the mass was reported as high-grade leiomyosarcoma. The formation of this giant retroperitoneal mass in 1 year can be explained by the transformation of the lesion's pathology from low-grade to a high-grade tumor. PMID:27436926

    Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare catecholamine-secreting tumors derived from chromaffin cells originating in the neural crest. These tumors represent a significant diagnostic and therapeutic challenge because the diagnosis of malignancy is frequently made in retrospect by the development of metastatic or recurrent disease. Complete surgical resection offers the only potential for cure; however, recurrence can occur even after apparently successful resection of the primary tumor. The prognosis for malignant disease is poor because traditional treatment modalities have been limited. The last decade has witnessed exciting discoveries in the study of PCCs and PGLs; advances in molecular genetics have uncovered hereditary and germline mutations of at least 10 genes that contribute to the development of these tumors, and increasing knowledge of genotype-phenotype interactions has facilitated more accurate determination of malignant potential. Elucidating the molecular mechanisms responsible for malignant transformation in these tumors has opened avenues of investigation into targeted therapeutics that show promising results. There have also been significant advances in functional and radiological imaging and in the surgical approach to adrenalectomy, which remains the mainstay of treatment for PCC. In this review, we discuss the currently available diagnostic and therapeutic options for patients with malignant PCCs and PGLs and detail the molecular rationale and clinical evidence for novel and emerging diagnostic and therapeutic strategies.

  10. Imaging of prostate cancer local recurrences: why and how?

    International Nuclear Information System (INIS)

    Because prostate cancer local recurrences can be efficiently treated by salvage therapies, it becomes critical to detect them early. The first alert is the rise of the prostate specific antigen (PSA) level after the post-treatment nadir, which can correspond to a distant recurrence, a local recurrence or both. This so-called biochemical failure (BF) is defined as PSA level >0.2 ng/ml after radical prostatectomy (RP) and PSA level > nadir+2 ng/ml after radiotherapy. There is no consensual definition of BF after cryotherapy, high-intensity focused ultrasound (HIFU) ablation or brachytherapy. Local recurrences after RP are treated by radiotherapy, those after radiotherapy by RP, cryotherapy, brachytherapy or HIFU ablation. Recurrences after cryotherapy or HIFU ablation can be treated by a second session or radiotherapy. Recurrences after brachytherapy are difficult to treat. In patients with BF, MRI can detect local recurrences, whatever the initial treatment was. Dynamic contrast-enhanced MRI seems particularly accurate. The role of spectroscopy remains controversial. Ultrasound-based techniques are less accurate, but this may change with the advent of ultrasonic contrast media. These recent advances in imaging may improve the outcome of salvage therapies (by improving patient selection and treatment targeting) and should open the way to focal salvage treatments in the near future.

    Metastatic gastric cancer is uncommon, and metastasis of colorectal cancer to the stomach is extremely rare. We report a case of metastatic gastric cancer that originated from transverse colon cancer. A 52-year-old woman underwent a left hemicolectomy and D3 lymph node dissection based on a diagnosis of transverse colon cancer. The pathology results were as follows: mucinous adenocarcinoma, type 2, 6 × 11 cm, ss, ly1 v1, pm (-), dm (-), n1 (+), P0, H0, M0, Stage IIIa. The patient received XELOX as postoperative adjuvant therapy for 6 months. One year and 3 months after the left hemicolectomy, gastroscopy revealed a submucosal tumor in the lower body of the stomach and an incipient cancer in the cardia of the stomach, and a colonoscopy revealed an incipient cancer in the transverse colon. An endoscopic ultrasonography fine needle aspiration biopsy of the submucosal tumor in the lower body of the stomach was performed. Histology showed that this tumor was a mucinous adenocarcinoma similar to the primary transverse colon cancer, which led to a diagnosis of metastatic gastric cancer originating from transverse colon cancer. Distant metastasis was not detected. Endoscopic submucosal dissection of the incipient gastric cancer was performed, as were distal gastrectomy and partial colectomy. Peritoneal dissemination and para-aortic lymph node recurrence were detected 7 months after the second surgery.

    In a 12-month period, metastatic cancer was diagnosed in eight patients. Six of them presented with pain mimicking toothache, temporomandibular joint disorders or trigeminal neuralgia, while two showed osteopenic bone lesions in the panoramic radiography, and perimandibular swelling. Anesthesia of the lower lip was the only common clinical feature. In seven of the eight patients, a whole body bone scintigraphy and single photon emission computed tomography (SPECT) of the skull in combination with a whole body and SPECT anti-granulocyte (Tc-99m MAK 250/183) bone marrow scintigraphy was performed. One patient did not have combined scintigraphy performed secondary to severe systemic illness. In six of the seven, the results were conclusive for a metastatic bone lesion. Biopsies confirmed three patients to have a previously unrecognized primary cancer, one patient to have previously unrecognized recurrent cancer, and three patients to exhibit new metastatic spread of an already diagnosed cancer. Histology revealed breast, lung, renal cancer and a malignancy of inconclusive origin. In the remaining patient, combined scintigraphy suggested osteomyelitis, yet biopsy revealed a prostate cancer metastasis with acute inflammatory cell infiltration. Thus, the scintigraphy pattern of a hot spot in the bone scan and a cold lesion in the bone marrow scintigraphy is highly suggestive of a mandibular metastasis, if accompanied by anesthesia of the lower lip.

    This descriptive study of the perceptions and needs of people with recurrent malignancies asks three questions: How do patients describe the meaning of a recurrence of cancer? Do individuals perceive the diagnosis of recurrence and the initial diagnosis of cancer differently? What are the key psychosocial problems associated with recurrent cancer? The theoretical framework was based on Lazarus and Folkman's theory of stress, appraisal, and coping. Subjects completed the Impact of Event Scale (IES), the Psychosocial Adjustment to Illness Scale--Self-Report (PAIS), and a semistructured qualitative interview. The interview elicited perceptions of the event of recurrence and differences between the diagnosis of recurrence and the initial diagnosis. The convenience sample included 40 patients diagnosed with recurrent cancer within the last 30 days. Many subjects (78%) reported that the recurrence was more upsetting than the initial diagnosis. Scores on both the IES and the PAIS were high when compared to normative samples of patients with cancer suggesting that this sample of patients experienced a lot of psychological distress as well as problems at home, work, and in their social lives. These concerns often were unknown to caregivers. Although more research is needed, the authors propose that, with more accurate assessment, more effective intervention could be implemented and the quality of life improved for patients with recurrent cancer.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    The existing approach to characterize cell biomechanical properties typically utilizes switch-like models of mechanotransduction in which cell responses are analyzed in response to a single nanomechanical indentation or a transient pulsed stress. Although this approach provides effective descriptors at population-level, at a single-cell-level, there are significant overlaps in the biomechanical descriptors of non-metastatic and metastatic cells which precludes the use of biomechanical markers for single cell metastatic phenotyping. This study presents a new promising marker for biosensing metastatic and non-metastatic cells at a single-cell-level using the effects of a dynamic microenvironment on the biomechanical properties of cells. Two non-metastatic and two metastatic epithelial breast cell lines are subjected to a pulsed stresses regimen exerted by atomic force microscopy. The force-time data obtained for the cells revealed that the non-metastatic cells increase their resistance against deformation and become more stiffened when subjected to a series of nanomechanical indentations. On the other hand, metastatic cells become slightly softened when their mechanical microenvironment is subjected to a similar dynamical changes. This distinct behavior of the non-metastatic and metastatic cells to the pulsed stresses paradigm provided a signature for single-cell-level metastatic phenotyping with a high confidence level of ∼95%.

    In 2014, prostate cancer will affect roughly 15 % of American men during their lifetimes with about 230,000 new cases and 29,000 deaths per year. If required, most can be treated with curative surgery or radiotherapy. Upon relapse, androgen deprivation therapy (intermittent or continuous) is the cornerstone of treatment for hormone-sensitive disease. Response is variable and treatment is associated with a significant risk of toxicity. Recently, significant advances in survival have been demonstrated with chemohormonal therapy in men with high-volume disease. In addition, new findings have informed the approach to preventing bone complications in patients on therapy for metastatic hormone-sensitive prostate cancer. Devising clinical prediction tools and biomarkers is needed to select patients most likely to benefit from certain therapies and allow for a personalized approach. PMID:25677237

    Full Text Available Background: Adjuvant radiotherapy reduces nodal recurrence in metastatic melanoma. The purpose of this study was to examine the effects of adjuvant radiotherapy on in-field nodal control of melanoma metastatic to axillary and inguinal lymph nodes. Methods: The medical records of patients who received adjuvant radiotherapy from January 1, 2003, through December 31, 2011, at Mayo Clinic were reviewed. Results: In the 20 patients identified, the rates of 2-year overall survival, nodal control, and freedom from distant metastases were 53%, 54%, and 44%, respectively. Intensity-modulated radiotherapy was used in 15 patients (75% and 3-dimensional conformal radiotherapy in 5 (25%. Disease progression was documented in 13 patients, with a total of 10 distant metastases and 6 in-field nodal recurrences. Treatment complications occurred in 14 patients: lymphedema, 9; lymphedema and fibrosis, 1; lymphedema and wound dehiscence, 1; wound dehiscence, 1; lymphedema and seroma, 1; and lymphedema, seroma, and fibrosis, 1. Conclusion: Patients with axillary and inguinal nodal metastases from melanoma have poor overall survival. Surgery and adjuvant radiotherapy provided a 54% nodal control rate. No plexopathy or grade 3 lymphedema complications were seen; however, 20% developed wound dehiscence.

    Full Text Available This report describes the clinical and pathological aspects of an apocrine sweat gland carcinoma with distant metastasis in an aged dog. A 7-year-old male terrier dog was referred to small animal hospital of Shahid Bahonar University of Kerman with a 5.5×3.5 centimeter pedunculated mass on its head near left auricular region which had been progressively growing since three months ago. The radiography showed no local and distant metastasis. Surgical excision and histological evaluation was done. Histologically, the mass was composed of epithelial cells arranged in glandular and solid patterns. The morphologic findings suggested either a primary or metastatic apocrine-gland carcinoma. Immunohistochemically, the tumor cells were intensely positive for cytokeratin 7 and 20 and negative for S100 protein. On the basis of histopathological and clinical findings, the tumor was diagnosed as a malignant apocrine gland tumor, arising from apocrine sweat glands of the skin. Local tumor recurrence with anorexia and weight loss was reported by the owner nine month later. Severe submandibular and prescapular lymphadenomegaly was noted in clinical examination. Several large pulmonary nodules were noted in chest radiographs resembling mediastinal lymph node metastasis. Second surgery and chemotherapy was rejected by the owner due to grave prognosis of the patient. The animal was died 45 days later due to respiratory complications. Tumors of apocrine sweat glands are relatively uncommon in dogs whereas apocrine gland adenocarcinoma with distant metastasis is extremely rare.

    Medulloblastoma, the most common malignant paediatric brain tumour, arises in the cerebellum and disseminates through the cerebrospinal fluid in the leptomeningeal space to coat the brain and spinal cord. Dissemination, a marker of poor prognosis, is found in up to 40% of children at diagnosis and in most children at the time of recurrence. Affected children therefore are treated with radiation to the entire developing brain and spinal cord, followed by high-dose chemotherapy, with the ensuing deleterious effects on the developing nervous system. The mechanisms of dissemination through the cerebrospinal fluid are poorly studied, and medulloblastoma metastases have been assumed to be biologically similar to the primary tumour. Here we show that in both mouse and human medulloblastoma, the metastases from an individual are extremely similar to each other but are divergent from the matched primary tumour. Clonal genetic events in the metastases can be demonstrated in a restricted subclone of the primary tumour, suggesting that only rare cells within the primary tumour have the ability to metastasize. Failure to account for the bicompartmental nature of metastatic medulloblastoma could be a major barrier to the development of effective targeted therapies. PMID:22343890

    Recurrent vulvovaginal candidiasis (RVVC) is a common cause of significant morbidity in women in all strata of society affecting millions of women worldwide. Previously, RVVC occurrence was limited by onset of menopause but the widespread use of hormone replacement therapy has extended the at-risk period. Candida albicans remains the dominant species responsible for RVVC, however optimal management of RVVC requires species determination and effective treatment measures are best if species-specific. Considerable progress has been made in understanding risk factors that determine susceptibility to RVVC, particularly genetic factors, as well as new insights into normal vaginal defense immune mechanisms and their aberrations in RVVC. While effective control of RVVC is achievable with the use of fluconazole maintenance suppressive therapy, cure of RVVC remains elusive especially in this era of fluconazole drug resistance. Vaccine development remains a critical challenge and need.

    Spontaneous hemoperitoneum (SP) is defined as the presence of blood within the peritoneal cavity that is unrelated to trauma.Although there is a vast array of etiologies for SP,primary hepatocellular carcinoma and hepatic adenoma are considered to be the most common causes.Hepatic metastatic tumor associated with spontaneous rupture is rare.SP from hepatic metastatic trophoblastic tumor may initially present with a sudden onset of abdominal pain.Abdominal computed tomography (CT) plays an important role in establishing the diagnosis of SP,indicating its origin and etiology,and determining subsequent management.Herein,we report an uncommon case of hemoperitoneum from spontaneous rupture of a hepatic metastatic trophoblastic tumor in a young female patient.Interestingly,the contrast-enhanced CT findings demonstrated hypervascular hepatic masses with persistent enhancement at all phases,which were completely different from the common appearances of hepatic metastases.For SP resulting from hepatic metastatic tumors,surgical intervention is still the predominant therapeutic method,but the prognosis is very poor.

  17. Targeted biomarker profiling of matched primary and metastatic estrogen receptor positive breast cancers.

    Directory of Open Access Journals (Sweden)

    Erica B Schleifman

    Full Text Available Patients with newly diagnosed, early stage estrogen receptor positive (ER+ breast cancer often show disease free survival in excess of five years following surgery and systemic adjuvant therapy. An important question is whether diagnostic tumor tissue from the primary lesion offers an accurate molecular portrait of the cancer post recurrence and thus may be used for predictive diagnostic purposes for patients with relapsed, metastatic disease. As the class I phosphatidylinositol 3' kinase (PI3K pathway is frequently activated in ER+ breast cancer and has been linked to acquired resistance to hormonal therapy, we hypothesized pathway status could evolve over time and treatment. Biomarker analyses were conducted on matched, asynchronous primary and metastatic tumors from 77 patients with ER+ breast cancer. We examined whether PIK3CA and AKT1 alterations or PTEN and Ki67 levels showed differences between primary and metastatic samples. We also sought to look more broadly at gene expression markers reflective of proliferation, molecular subtype, and key receptors and signaling pathways using an mRNA analysis platform developed on the Fluidigm BioMark™ microfluidics system to measure the relative expression of 90 breast cancer related genes in formalin-fixed paraffin-embedded (FFPE tissue. Application of this panel of biomarker assays to matched tumor pairs showed a high concordance between primary and metastatic tissue, with generally few changes in mutation status, proliferative markers, or gene expression between matched samples. The collection of assays described here has been optimized for FFPE tissue and may have utility in exploratory analyses to identify patient subsets responsive to targeted therapies.

    Cervical cancer remains unique among solid tumor malignancies. Persistent infection with oncogenic subtypes of the human papillomavirus (HPV) results in carcinogenesis, predominantly occurring at the cervical transformation zone where endocervical columnar cells undergo metaplasia to a stratified squamous epithelium. The molecular cascade involving viral oncoproteins, E6 and E7 and their degradative interactions with cellular tumor suppressor gene products, p53 and pRb, respectively, has been precisely delineated. The precursor state of cervical neoplasia may last for years allowing for ready detection through successful screening programs in developed countries using cervical cytology and/or high-risk HPV DNA testing. Prophylactic HPV L1 capsid protein vaccines using virus-like-particle technology have been developed to prevent primary infection by the most common high-risk HPVs (16 and 18). Women who lack access to health care and those who undergo sporadic screening remain at risk. Although radical surgery (including fertility-sparing surgery) is available for patients with early-stage cancers, and chemoradiation plus high-dose-rate brachytherapy can cure the majority of those with locally advanced disease, patients with metastatic and nonoperable recurrent cervical cancer constitute a high-risk population with an unmet clinical need. On August 14, 2014, the FDA approved the antiangiogenesis drug bevacizumab for women with advanced cervical cancer. This review will highlight advances in translational science, antiangiogenesis therapy and immunotherapy for advanced disease. PMID:25104084

    Local recurrence of rectal cancer is difficult to treat, may cause severe and disabling symptoms, and usually has a fatal outcome. The aim of this study was to document the clinical nature of locally recurrent rectal cancer and to determine the effect of surgical resection on long-term survival.A retrospective review was conducted of the prospectively collected medical records of 2485 patients with primary rectal adenocarcinoma who underwent radical resection between September 1994 and December 2008.In total, 147 (5.9%) patients exhibited local recurrence. The most common type of local recurrence was lateral recurrence, whereas anastomotic recurrence was the most common type in patients without preoperative concurrent chemoradiotherapy (CCRT). Tumor location with respect to the anal verge significantly affected the local recurrence rate (P CRM (P = 0.001, RR = 12.939, 95% CI = 2.906-57.604), combined distant metastases (P = 0.001, RR = 2.086, 95% CI = 1.352-3.218), and nonsurgical resection of recurrent tumor (P < 0.001, RR = 4.865, 95% CI = 2.586-9.153).In conclusion, the clinical outcomes of local recurrence after curative resection of rectal cancer are diverse. Surgical resection of locally recurrent rectal cancer should be considered as an initial treatment, especially in patients with less advanced tumors and axial recurrence. PMID:27399067

    OBJECTIVE To identify clinicopathological characteristics as predictive factors for recurrence in early gastric cancer (EGC), and to determine which lesions should be removed by gastrectomy by means other than endoscopic mucosal resection (EMR).METHODS Data from 249 patients with EGC were collected and the relationship between their clinicopathological characteristics and postoperative recurrence was retrospectively analyzed by univariate analysis.RESULTS Of the 249 patients after gastrectomy, 19 cases (7.6%)experienced a recurrence. The postoperative recurrence rate was 18.9%(7/37) in patients with lymph node metastasis, and 5.7%(12/212) in those without. Lymph node metastases were found to be significantly related to recurrence in EGC (P = 0.005).CONCLUSION Lymph node metastases were the only predictive factor for recurrence in EGC. However, this was not the determining factor for performing gastrectomy rather than EMR. Although after gastrectomy with lymphadenectomy of EGC, patients with lymph node metastasis should be considered as candidates for adjuvant treatment. For lymph-node metastatic EGCs, adjuvant therapy is recommended following gastrectomy with lymphadenectomy.

    Objective To evaluate the killing effect by PA-MSHA vaccine on gastric cancer cells in vitro and its effect on the prophylaxis of post-operative intraperitoneal recurrence and metastasis in advanced gastric cancer. Methods MTT method was used to observe the inhibition and killing effect by PA-MSHA vaccine on gastric cancer cell strain MKN45 between January 2005 and December 2007 at Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Specific combination and inhibition of cell proliferation were observed by transmission electron microscopy. Sixty cases of advanced gastric cancer T3M0 were selected into the study which were randomly separated into two groups: PA-MSHA group and control group. It observed side effects, effect on the patients' immune function and intraperitoneal recurrence or metastasis. Results PA-MSHA vaccine could specifically combine and penetrate into the gastric cancer cell strain MKN45 so as to inhibit its proliferation and the killing effect was in direct proportion to its dose. The side effect of PA-MSHA vaccine was comparatively limited. In PA-MSHA group, the cellular immune function was strengthened and intraperitoneal recurrence or metastasis decreased significantly. Conclusion PA-MSHA vaccine has dose-dependent killing effect on gastric cancer cell strain MKN45 by specific combination. It is safe and feasible which can strengthen the cellular immune function and reduce intraperitoneal recurrence or metastasis in advanced gastric cancer.%目的 探讨铜绿假单胞菌注射液在体外对胃癌细胞杀伤作用,并观察其在进展期胃癌围手术期应用对预防术后腹腔复发与转移的作用.方法 2005年1月至2007年12月上海交通大学医学院附属仁济医院普外科采用四甲基偶氮唑盐(MTT)法观察铜绿假单胞菌注射液抑制胃癌瘤株MKN45细胞增殖和杀伤作用的剂量依赖性;采用扫描电镜观察对胃癌瘤株MKN45的特异性结合.在此基础上选择T3MO

    Renal cell carcinoma (RCC) is the most common renal tumor, accounting for 2% -3% of all malignancies.Though RCC is known to spread hematogenously, isolated RCC metastasis to the stomach is a rare event. In this article, we describe the clinical course of a patient who developed a pancreatic recurrence of RCC and 1 year later a gastric recurrence of RCC treated 10 years ago with a resection and interleukin-2 (IL-2).Accumulating evidence indicates that metastatic involvement of the pancreas and stomach should be suspected in any patient with a history of RCC who presents with gastrointestinal symptoms even 10 years after RCC resection and immunotherapy.

    PIK3CA gene is frequently mutated in patients with breast cancer and it has been the focus of intense research. Inhibitors of PI3K pathway are being evaluated in ongoing clinical trials but the impact of PIKC3A mutation status on tumor response is yet uncertain. In the metastatic setting, several studies are evaluating the predictive value of PIK3CA mutations. However, results could be biased by biopsy localization. Digital polymerase chain reaction is a new technology that enables detection and quantification of cancer DNA molecules from peripheral blood and can potentially overcome such situation. As a proof of the concept, we present the case of a metastatic patient with a PIK3CA wild-type primary tumor in which the PIK3CA E545K mutation was identified in both the circulating-free DNA obtained from a peripheral blood sample and in the formalin-fixed, paraffin-embedded liver metastasis.

    The reported positions of 964 suspected nova eruptions in M31 recorded through the end of calendar year 2013 have been compared in order to identify recurrent nova candidates. To pass the initial screen and qualify as a recurrent nova candidate two or more eruptions were required to be coincident within 0.1', although this criterion was relaxed to 0.15' for novae discovered on early photographic patrols. A total of 118 eruptions from 51 potential recurrent nova systems satisfied the screening criterion. To determine what fraction of these novae are indeed recurrent the original plates and published images of the relevant eruptions have been carefully compared. This procedure has resulted in the elimination of 27 of the 51 progenitor candidates (61 eruptions) from further consideration as recurrent novae, with another 8 systems (17 eruptions) deemed unlikely to be recurrent. Of the remaining 16 systems, 12 candidates (32 eruptions) were judged to be recurrent novae, with an additional 4 systems (8 eruptions) b...

    Highlights: • Colorectal cancer is the third most prevalent cancer and the status of the regional lymph nodes in rectal cancer is considered to be one of the most powerful prognostic factor in the absence of distant metastatic disease. Detecting LNs metastasis is still a challenging problem due to the presence of microscopic metastasis or inflammatory swelling of LNs. • We investigated the value of dual energy spectral CT in differentiating metastatic from non-metastatic lymph nodes in rectal cancer. Our study demonstrated that the quantitative normalized iodine concentration (nIC) could be useful for differentiating metastatic and non-metastatic lymph nodes. The combination of nIC in portal venous phase and conventional size criterion could improve the diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value of rectal cancer. - Abstract: Objectives: To investigate the value of dual energy spectral CT (DEsCT) imaging in differentiating metastatic from non-metastatic lymph nodes in rectal cancer. Methods: Fifty-five patients with rectal cancer underwent the arterial phase (AP) and portal venous phase (PP) contrast-enhanced DEsCT imaging. The virtual monochromatic images and iodine-based material decomposition images derived from DEsCT imaging were interpreted for lymph nodes (LNs) measurement. The short axis diameter and the normalized iodine concentration (nIC) of metastatic and non-metastatic LNs were measured. The two-sample t test was used to compare the short axis diameters and nIC values of metastatic and non-metastatic LNs. ROC analysis was performed to assess the diagnostic performance. Results: One hundred and fifty two LNs including 92 non-metastatic LNs and 60 metastatic LNs were matched using the radiological-pathological correlation. The mean short axis diameter of metastatic LNs was significantly larger than that of the non-metastatic LNs (7.28 ± 2.28 mm vs. 4.90 ± 1.64 mm, P < 0.001). The mean n

    Malignant melanoma requires precise resection in order to avoid metastatic recurrence. We report here that the telomerase-dependent, green fluorescent protein (GFP)-containing adenovirus OBP-401 could label malignant melanoma with GFP in situ in orthotopic mouse models. OBP-401-based fluorescence-guided surgery (FGS) resulted in the complete resection of malignant melanoma in the orthotopic models, where conventional bright-light surgery (BLS) could not. High-dose administration of OBP-401 enabled FGS without residual cancer cells or recurrence, due to its dual effect of cancer-cell labeling with GFP and killing. PMID:26701857

    Full Text Available Recent results about spike-timing-dependent plasticity (STDP in recurrently connected neurons are reviewed, with a focus on the relationship between the weight dynamics and the emergence of network structure. In particular, the evolution of synaptic weights in the two cases of incoming connections for a single neuron and recurrent connections are compared and contrasted. A theoretical framework is used that is based upon Poisson neurons with a temporally inhomogeneous firing rate and the asymptotic distribution of weights generated by the learning dynamics. Different network configurations examined in recent studies are discussed and an overview of the current understanding of STDP in recurrently connected neuronal networks is presented.

    Full Text Available Anuj Patel, Weijing Sun Division of Hematology-Oncology, University of Pittsburgh Cancer Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA, USA Abstract: The combination of cytotoxic chemotherapy and antiangiogenic agents has become a conventional treatment option for patients with metastatic colorectal cancer. Ziv-aflibercept is a fusion protein which acts as a decoy receptor for vascular endothelial growth factor (VEGF-A, VEGF-B, and placental growth factor (PlGF; it was approved in combination with 5-fluorouracil, leucovorin, and irinotecan (FOLFIRI for the treatment of patients with metastatic colorectal cancer that is resistant to or has progressed after an oxaliplatin-containing fluoropyrimidine-based regimen. Herein we review the role of tumor angiogenesis as the rationale for antiangiogenic therapy, the clinical data associated with ziv-aflibercept, and its current role as a treatment option compared to other antiangiogenic agents, such as bevacizumab and regorafenib. Keywords: aflibercept, angiogenesis, colorectal cancer

    Actinomycosis is a chronic suppurative infection with bacteria of the Actinomycetaceae family, characterized by the formation of abundant granular tissue and multiple abscesses. It is a rare entity, and clinical and radiological findings are similar to those in other inflammatory and in neoplastic processes. Actinomycosis should be considered in the differential diagnosis in high-risk patients with predisposing factors, such as alcoholism, poor oral hygiene, maxillofacial trauma, tuberculosis, chronic obstructive pulmonary disease, steroid ingestion or immunodeficiency, and in patients in whom the disease history does not correlate with widespread metastatic involvement. Early diagnosis is important, to prevent disease progression and unnecessary surgery, since the response to drug treatment is very good. We present a case of diffuse actinomycosis involving multiple organs (liver, kidneys, colon, and lungs) that simulated metastatic disease on radiography and computed tomography (CT). (author)

    Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

    Full Text Available Neuroblastoma (NB is the most commonly occurring solid tumor in children. The disease usually arises in the adrenal medulla, and it is characterized by a remarkable heterogeneity in its progression. Most NB patients with an advanced disease have massive bone marrow infiltration at diagnosis. Lung metastasis represents a widely disseminated stage and is typically considered to be a terminal event. Much like other malignancies, NB progression is a complex, multistep process. The expression, function, and significance of the various factors involved in NB progression must be studied in relevant in vivo and in vitro models. Currently, models consisting of metastatic and nonmetastatic cell variants of the same genetic background exist for several types of cancer; however, none exists for NB. In the present study, we describe the generation of a NB metastasis model. SH-SY5Y and MHH-NB-11 NB cells were inoculated orthotopically into the adrenal glands of athymic nude mice. Neuroblastoma cells metastasizing to the lungs were isolated from mice bearing adrenal tumors. Lung metastatic variants were generated by repeated cycles of in vivo passage. Characterization of these variants included cellular morphology and immunophenotyping in vitro, aggressiveness in vivo, and various biologic parameters in vitro. The NB metastatic variant in each model displayed unique properties, and both metastatic variants demonstrated a metastatic phenotype in vivo. These reproducible models of human NB metastasis will serve as an unlimited source of transcriptomic and proteomic material. Such models can facilitate future studies on NB metastasis and the identification of novel NB biomarkers and targets for therapy.

    Metastatic renal cell carcinoma (RCC) has historically been refractory to cytotoxic and hormonal agents; only interleukin 2 and interferon alpha provide response in a minority of patients. We reviewed RCC biology and explored the ways in which this understanding led to development of novel, effective targeted therapies. Small molecule tyrosine kinase inhibitors, monoclonal antibodies and novel agents are all being studied, and phase II studies show promising activity of sunitinib, sorafenib a...

    Pulmonary hyalinizing granuloma is a very rare benign condition, which usually manifests as solitary and sometimes as multiple pulmonary nodules. Deposition of immune complexes in the lung parenchyma due to hypersensitivity reactions is implicated in the etiology of pulmonary hyalinizing granuloma. A 59-year-old female patient who presented to our clinic with complaints of chest pain and cough had bilateral, multiple, and rounded lesions with regular margins suggesting metastatic lung disease...
