  1. Comparison of anthracycline-based combination chemotherapy with or without all-trans retinoic acid in acute promyelocytic leukemia

    International Nuclear Information System (INIS)

    To compare survival in Acute Promyelocytic Leukemia (APL) patients treated with or without All-Trans Retinoic Acid (ATRA). Longitudinal, comparative study. All consecutive newly diagnosed patients of acute promyelocytic leukemia, treated at Armed Forces Bone Marrow Transplant Centre, Rawalpindi, Pakistan, between May 2001 and April 2007, were included and given chemotherapy according to availability of ATRA. Diagnosis was confirmed on morphology/ karyotyping/ molecular analysis. Eligibility criteria included confirmed morphologic diagnosis and/or by demonstration of t(15;17) and/or PML/RAR macro re-arrangement, no prior chemotherapy, normal hepatic and renal function, Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 2 and no contraindications to ATRA (history of sensitivity to Vit. A or other retinoids). All patients having history of cardiac failure (LVEF 150 macro mol/L and pregnancy were excluded from this study. Survival was calculated from the date of chemotherapy to death or last follow-up according to Kaplan-Meier and Cox (Proportional hazard) regression analysis methods. During the 6 years study period, 31 newly diagnosed patients with acute promyelocytic leukemia received treatment at AFBMTC. Seventeen patients received anthracycline-based remission induction and consolidation chemotherapy, while 14 received ATRA-based remission induction, consolidation and by two years maintenance therapy. Overall Survival (OS), Disease Free Survival (DFS) and mortality were 29.4%, 29.4% and 70.6% respectively in 17 patients who received anthracycline based chemotherapy, whereas in patients who received ATRA-based chemotherapy OS, DFS and mortality was 71.4%, 64.2% and 28.6% respectively. Major causes of mortality were septicemia and chemotherapy related toxicity. Response to ATRA-based chemotherapy in patient cohort was better as compared with anthracycline based chemotherapy (71.4% vs. 29.4%) in terms of survival and mortality. (author)

    Purpose Approximately 35% of HER2-amplified breast cancers have coamplification of the topoisomerase II-alpha (TOP2A) gene encoding an enzyme that is a major target of anthracyclines. This study was designed to evaluate whether TOP2A gene alterations may predict incremental responsiveness to anthracyclines in some breast cancers. Methods A total of 4,943 breast cancers were analyzed for alterations in TOP2A and HER2. Primary tumor tissues from patients with metastatic breast cancer treated in a trial of chemotherapy plus/minus trastuzumab were studied for amplification/deletion of TOP2A and HER2 as a test set followed by evaluation of malignancies from two separate, large trials for changes in these same genes as a validation set. Association between these alterations and clinical outcomes was determined. Results Test set cases containing HER2 amplification treated with doxorubicin and cyclophosphamide (AC) plus trastuzumab, demonstrated longer progression-free survival compared to those treated with AC alone (P = .0002). However, patients treated with AC alone whose tumors contain HER2/TOP2A coamplification experienced a similar improvement in survival (P = .004). Conversely, for patients treated with paclitaxel, HER2/TOP2A coamplification was not associated with improved outcomes. These observations were confirmed in a larger validation set, where HER2/TOP2A coamplification was again associated with longer survival when only anthracycline-containing chemotherapy was used for treatment compared with outcome in HER2-positive cancers lacking TOP2A coamplification. Conclusion In a study involving nearly 5,000 breast malignancies, both test set and validation set demonstrate that TOP2A coamplification, not HER2 amplification, is the clinically useful predictive marker of an incremental response to anthracycline-based chemotherapy. Absence of HER2/TOP2A coamplification may indicate a more restricted efficacy advantage for breast cancers than previously thought. PMID

    In breast cancer, recent studies suggest that the value of HER2 for predicting response to anthracycline-based chemotherapy may be more likely related to the concomitant amplification of the TOP2A gene. Here, we study the association between HER2 or TOP2A status and response to anthracycline-based preoperative chemotherapy and explore the interaction between HER2 or TOP2A status and intense dose-dense (IDD) chemotherapy. HER2 and TOP2A gene alterations were quantified by fluorescence in situ hybridization in primary tumor core biopsies from 373 high-risk primary breast cancer patients (tumors >/=3 cm or inflammatory) that received an IDD or conventionally scheduled anthracycline-based preoperative chemotherapy. HER2 was amplified in 94/350 tumors (27%) of which 40/94 (46%) demonstrated TOP2A amplification, and 17/94 (18%) TOP2A deletions. TOP2A gene alterations were not found in HER2 non-amplified cases. HER2 amplification was associated with a significantly higher pathologic complete response (pCR) rate only when TOP2A was co-amplified (30% vs. 11%, P = 0.002), but not when deleted (13% vs. 11%, P = 0.755), or normal (14% vs. 11%, P = 0.578) compared to HER2 non-amplified tumors. In multivariate analysis, TOP2A amplification (odds ratio [OR] 3.04, P = 0.021), but not HER2 amplification (OR 1.74, P = 0.170) was associated with a significantly higher pCR rate. No interaction was observed between HER2 or TOP2A status and IDD chemotherapy. TOP2A gene amplification may define a subset of HER2-amplified breast cancers that are responsible for the markedly improved chemosensitivity seen in HER2-positive breast cancer. However, added benefit of IDD chemotherapy itself was not associated with HER2 or TOP2A status. PMID:20130985

    An increasing number of older patients are suffering from aggressive lymphoma. Effective and more tolerable treatment regimens are urgently needed for this growing patient population. Patients with aggressive lymphoma not eligible for anthracycline-based first-line therapy or intensive salvage regimens were treated with the rituximab-bendamustine-lenalidomide (R-BL) regimen (rituximab 375 mg/m(2)  day 1, bendamustine 70 mg/m(2)  d 1, 2, lenalidomide 10 mg d 1-21) for six cycles every 4 weeks. Forty-one patients with a median age of 75 (range 40-94) years were enrolled: 33 patients had substantial co-morbidities. 13 patients were not eligible for anthracycline-based first-line chemotherapy, 28 patients had relapsed/refractory disease. The primary endpoint, overall response, was achieved by 25 (61%) patients (95% confidence interval 45-76%). Grade ≥ 3 toxicity comprised haematological (59%), skin (15%), constitutional (15%) and neurological (12%) events. 9 patients died during trial treatment: 5 from lymphoma progression, 2 from toxicity, 2 with sudden death. After a median follow-up of 25·9 (interquartile range 20·4-31·6) months, 13 patients were still alive. Median overall survival was 14·5 months. In conclusion, R-BL can be considered a treatment option for elderly patients with treatment naïve or relapsed/refractory aggressive lymphoma not eligible for standard aggressive regimens.

    Full Text Available BACKGROUND: The aim of the present study was to investigate the efficacy of adjuvant dose-dense sequential chemotherapy with epirubicin, paclitaxel, and CMF in subgroups of patients with high-risk operable breast cancer, according to tumor subtypes defined by immunohistochemistry (IHC. MATERIALS AND METHODS: Formalin-fixed paraffin-embedded (FFPE tumor tissue samples from 1,039 patients participating in two adjuvant dose-dense sequential chemotherapy phase III trials were centrally assessed in tissue micro-arrays by IHC for 6 biological markers, that is, estrogen receptor (ER, progesterone receptor (PgR, HER2, Ki67, cytokeratin 5 (CK5, and EGFR. The majority of the cases were further evaluated for HER2 amplification by FISH. Patients were classified as: luminal A (ER/PgR-positive, HER2-negative, Ki67(low; luminal B (ER/PgR-positive, HER2-negative, Ki67(high; luminal-HER2 (ER/PgR-positive, HER2-positive; HER2-enriched (ER-negative, PgR-negative, HER2-positive; triple-negative (TNBC (ER-negative, PgR-negative, HER2-negative; and basal core phenotype (BCP (TNBC, CK5-positive and/or EGFR-positive. RESULTS: After a median follow-up time of 105.4 months the 5-year disease-free survival (DFS and overall survival (OS rates were 73.1% and 86.1%, respectively. Among patients with HER2-enriched tumors there was a significant benefit in both DFS and OS (log-rank test; p = 0.021 and p = 0.006, respectively for those treated with paclitaxel. The subtype classification was found to be of both predictive and prognostic value. Setting luminal A as the referent category, the adjusted for prognostic factors HR for relapse for patients with TNBC was 1.91 (95% CI: 1.31-2.80, Wald's p = 0.001 and for death 2.53 (95% CI: 1.62-3.60, p<0.001. Site of and time to first relapse differed according to subtype. Locoregional relapses and brain metastases were more frequent in patients with TNBC, while liver metastases were more often seen in patients with HER2-enriched tumors

  7. Combining chemotherapy with radiation in breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is one of the most important global health problems. Over the last years introduction of mammography screening and increased efficacy of adjuvant therapies resulted in the reduction of mortality in this malignancy. A proportion of patients with breast cancer has indications for adjuvant radiotherapy and chemotherapy, however optimal schedules of combining these two modalities remain controversial. In clinical practice typically chemotherapy and radiotherapy are used sequentially, but this strategy is not supported by the results of large clinical trials. There is theoretical rationale for the concomitant use of both modalities, but increased cardiotoxicity and skin reactions of anthracycline-based regimens do not allow for this strategy. Further investigations are essential to determine the safety of taxane-based schedules combined with radiotherapy, particularly with regard to pneumotoxicity. Concurrent chemo-radiotherapy with the use of selected schemes may be considered in patients with locally advanced cancer, but this strategy still should be verified in large randomized studies.

    Full Text Available Introduction: The administration of neoadjuvant chemotherapy (NACT prior to local therapy is advantageous for women with locally advanced breast cancer (LABC, since it can render inoperable tumors resectable and can increase rates of breast conservative surgeries. Materials and Methods: We retrospectively analyzed LABC patients who received NACT from January 2000 to December 2007. Out of 3000 case records screened, 570 (19% were LABC and 110/570 (19% treatment-naïve patients started on NACT were analyzed. Ninety-one (37 docetaxel [D], 54 anthracycline [A] patients were eligible for response and survival analysis. Pathological complete remission (pCR was defined as no evidence of malignancy in both breast and axilla. Results: Median age of the whole cohort was 45 years (range 25-68 years. Premenopausal were 42% and estrogen receptor + 49.5%. Most (90% were T4 tumors and 70% were Stage IIIB. Median numbers of preoperative cycles were six and three in the D and A group respectively. Overall clinical response rates for breast primary were 74.3% and 53.7% (CR 28.6% vs. 16.7%, P=0.58 while for axilla ORR were 75.7% vs. 54.8% (51.4% vs. 40.4% CR, P=0.77 respectively for D and A. Corresponding pCR rates were 19% vs. 13% respectively. There was no significant difference in disease-free (three-year 56.84% vs. 61.16%, P=0.80 and overall survival (three-year 70% vs. 78.5%, P=0.86 between the two groups. Conclusions: Although pCR rates were higher with docetaxel-based NACT, it did not translate into superior disease-free survival / overall survival compared to anthracycline-based chemotherapies.

    Full Text Available The emergence of pandemic H1N1 influenza viruses in April 2009 and the continuous evolution of highly pathogenic H5N1 influenza viruses underscore the urgency of novel approaches to chemotherapy for human influenza infection. Anti-influenza drugs are currently limited to the neuraminidase inhibitors (oseltamivir and zanamivir and to M2 ion channel blockers (amantadine and rimantadine, although resistance to the latter class develops rapidly. Potential targets for the development of new anti-influenza agents include the viral polymerase (and endonuclease, the hemagglutinin, and the non-structural protein NS1. The limitations of monotherapy and the emergence of drug-resistant variants make combination chemotherapy the logical therapeutic option. Here we review the experimental data on combination chemotherapy with currently available agents and the development of new agents and therapy targets.

    International Nuclear Information System (INIS)

    The prospective study were to evaluate the efficacy and toxicity of Gemcitabine plus cisplatin as a first line chemotherapy in female patients with metastatic breast cancer who previously received anthracyclin-based regimen as adjuvant chemotherapy. Patients and Methods: Twenty five patients with metastatic and at least one bi-dimensionally measurable lesion were included in this study. Adequate bone marrow reserve, adequate hepatic and renal functions and performance status $ 2 were required. Patients have previously received anthracyclin based-chemotherapy as adjuvant. Treatment consisted of Gemcitabine 1250 mg/m2 on days I and 8 and cisplatin 75 mg/m2 on day I, cycles were repeated at 3-week intervals. 25 patients were evaluable for toxicity and 22 patients for response. Overall response was 54.5%. Complete response was reported in 13.6% of patients and partial response was reported in 40.9% of patients. Six patients (27.2%) had stable disease and disease progression was reported in (18.2%) of patients. Response was reported in all metastatic sites. Toxicities included grade 3,4 vomiting in 32% and grade 3, 4 neutropenia in 12%, grade 3, 4 thrompocytopenia in 32%. Only one case of neutropenic fever was reported. Renal and neurotoxicity was encountered in 12% and alopecia grade I. 2 in 8% of patients. o treatment related death was reported. The median overall survival was ]4.8 months (range: 2 to 18.5). Gemcitabine and cisplatin combination chemotherapy is active and well tolerated regimen for patients with metastatic breast cancer. This regimen represents a therapeutic option for patients receiving front line therapy for their metastatic breast cancer. Phase III randomized trial is needed for comparison with other 2nd line regimens to define the exact role of this combination

  15. Combined chemotherapy of malignant gliomas

    International Nuclear Information System (INIS)

    A controlled study of 226 age-matched patients with histologically proven grade 3 and 4 supratentorial gliomas with maximum feasible tumour resection, postoperative Karnofsky performance over 50 and minimum survival of 8 weeks compares the results of supportive care (45 cases), high-dose irradiation of 40 to 66 Gy (59 cases), COMP protocol (CCNU, procarbazine, vincristine, methotrexate, prednisone in 15 day cycles-42 cases) and simultaneous irradiation and COMP chemotherapy (80 cases including 30 survivors). Median recurrent-free intervals in the treatment groups (7 to 11.7 months) were significantly longer than after supportive care (4.4 months). Median survival with supportive care (6.7 months) was significantly shorter than after radiation or COMP treatment (11.7 and 12.3 months) and 14.9 to over 19.9 months with combined treatment, where the two-year survival rates were 33 and 67% (for survivors), and the 3-year survival rates 13 to 30%. Toxic side effects of multimodality treatment were more frequent than after chemotherapy. In addition to space-occupying intracranial cysts often simulating tumour recurrence (12%) and rare radiation necrosis, about 15% of long-term survivors developed progressive intellectual dysfunction with brain atrophy, in the absence of tumour regrowth. Despite some promising results of multimodality approaches towards the management of malignant supratentorial gliomas, the overall results are unsatisfactory and need further optimization. (Author)

    International Nuclear Information System (INIS)

    Compared to the other chemotherapeutic preparations discussed today, cyclophosphamide in combination with radiotherapy is a relatively unproblematic substance. Despite the great number of experimental and clinical data, the evaluation does not prove an advantage of the combined therapy with cyclophosphamide and irradiation as against radiotherapy alone in local tumor treatment. This should give occasion to further experimental investigations in adequate models. On the other hand, the practice of combined treatment with irradiation and preparations containing cyclophosphamide should be reconsidered for those cases where local control of a tumor is the principal therapeutic aim.

    OBJECTIVE The breast cancer lack of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) is defined as the Triple-negative breast cancer (TNBC). Our purpose is to compare the response and long-term effect of the TNBC and non-TNBC patients receiving neo-adjuvant anthracycline-based chemotherapy, and to investigate the mechanisms of TNBC affecting the survivals. METHODS Data of long-term follow-up (median, 5.4 years) of 326 patients who received neo-adjuvant chemotherapy with anthracycline-based regimen, during a period from 2000 to 2003, were analyzed. Expressions of ER, PR, HER-2, P53, Ki-67 and E-cadherin were determined using immunohistochemical staining method. A multivariate Cox regression analysis was used to analyze independent prognostic factors affecting the relapse-free survival (RFS) and overall survival (OS) rates. Clinical effects of the neo-adjuvant anthracycline-based chemotherapeutic regimen and the RFS and OS rates were compared between the patients with TNBC and non-TNBC, and the correlations among the triple- negative phenotype (TNP), tumor grading and the expressions of P53, Ki-67 and E-cadherins were analyzed. RESULTS TNP, TNM staging, histological grades, clinical response of the neo-adjuvant chemotherapy and pathological complete remission (pCR) rate were the independent prognostic factors affecting the survival rates. Furthermore, 70 (21.5%) of the 326 patients suffered TNBC. Compared with the subjects in non- TNBC group, the patients with TNBC had a significantly higher pCR rate (P=0.046) and clinical response rate (P=0.037), but also decreased 5-year RFS (P=0.001) and OS (P=0.004) rates. The RFS and OS rates were not improved in the TNBC patients who achieved a clinical remission after the neo-adjuvant chemotherapy. The triple-negative phenotype was positively correlated with the level of P53, Ki-67 expression (P=0.007, P=0.028), but negatively correlated with level of

  20. Combined radiotherapy and chemotherapy: pulmonary side effects

    International Nuclear Information System (INIS)

    Systemic chemotherapy and lung irradiation have very similar effects on lung tissue. Several mechanisms are involved, mainly: - cytotoxic effects on lung cells (type II pneumocytes, capillary endothelial cells, and connective tissue); - enhancement of infection; - hypersensitivity and auto-immune phenomena. Acute pneumonitis of chronic lung sclerosis develops which may or may not be compatible with life, depending on the lung volume involved and the clinical course. These effects are dose dependent for radiotherapy, and for most of the chemotherapeutic drugs. In some cases however, the dose-effect relationship is not clear, especially with some drugs such as methotrexate, and sometimes with radiotherapy even when it can be assumed that there is no mistake in dose calculation. It must be stressed that we still lack basic knowledge on the pharmacokinetics and actual concentration of drugs in lung tissue. Additive or supra-additive effects are likely when chemotherapy is combined with lung irradiation, but current relevant data does not allow any firm conclusions to be drawn on the quantitative changes resulting from the association. Prevention of lung complications is however possible if the tolerance doses and the optimal distribution of each agent with time are respected. Combined lung irradiation and bleomycin administration must be avoided

  1. 18F-fluorodeoxyglucose positron emission tomography optimizes neoadjuvant chemotherapy for primary breast cancer to achieve pathological complete response

    International Nuclear Information System (INIS)

    The background of this study was to assess the usefulness of positron emission tomography combined with computed tomography using 18F-fluorodeoxyglucose (FDG positron emission tomography (PET)/CT) for optimizing chemotherapy during neoadjuvant chemotherapy for primary breast cancer. One hundred and eight patients (110 tumors) with breast cancer (≥2 cm, stages II and III) received neoadjuvant chemotherapy consisting of an anthracycline-based regimen and taxane. The maximal value of the baseline standardized uptake value (SUV) and the change in SUV after four cycles of an anthracycline-based regimen relative to baseline SUV were assessed for predicting pathological complete response (pCR) after sequential taxane. Tumors with pCR had significantly higher baseline SUV (9.3±3.7 SD) compared to those with non-pCR (7.2±3.8 SD) (p=0.02), but there was a considerable overlap between two groups. On PET scan after four cycles of chemotherapy, thirty-three patients (33.7%) with a 72.1% or greater reduction in SUV were considered as responders and the performance in predicting pCR had a sensitivity of 88.9% and specificity of 78.7%. The baseline SUV could not be a useful indicator for predicting pCR due to the wide range in sensitivity. On the other hand, a relative change in SUV after completion of an anthracycline-based regimen could be useful for predicting pCR. (author)

    Full Text Available Background: Locally advanced breast cancer (LABC remains major clinical issue with regard to selection and duration of therapy since many years. Neoadjuvant chemotherapy (NACT is multimodality program, established to treat LABC. Many research tasks are ongoing to develop specific neoadjuvant chemotherapy regimen with specific duration to improve long-term control of LABC. Patients and Methods: Forty-seven patients diagnosed with LABC were Included and analyzed to compare the outcomes [pathological complete response (pCR, clinical response, overall response rate (ORR, disease control rate, overall survival and progression-free survival]. These patients treated with either combination of anthracycline and taxane-based chemotherapy or anthracycline-based chemotherapy. Results: There was no any statistical significance with respect to demographic data treated of patients between two arms (P > 0.05. Patients underwent TAC chemotherapy had pCR 20.8% whereas FAC/FEC chemotherapy patients had pCR 13% (P = 0.48. Higher ORR was noted in TAC chemotherapy arm (75% when compared with FAC/FEC chemotherapy arm (60.9% (P = 0.29. The study also shows better disease control rate in TAC chemotherapy arm (95.8% as compared to FAC/FEC chemotherapy arm (82.6%. There was no statistical significance in overall survival (P = 0.31 and progression-free survival (P = 0.51 between two arms. Conclusion: Despite of the superiority of combination of anthracycline and taxane-based chemotherapy over the anthracycline-based chemotherapy in the present study, further pivotal studies should be conducted to confirm the combination of anthracycline and taxane-based chemotherapy as a better neoadjuvant regimen for treatment of LABC tumors.

    Recently, by applying multidrug therapy using cisplatin and bleomycin to the treatment of head and neck cancer, the response rate of chemotherapy has been markedly increased and thus, chemotherapy has taken an important part in the treatment of head and neck cancer. In this paper a clinical application of chemotherapy in combination with radiotherapy was evaluated from the point of the cure rate and also preservation of the structures and the functions of the head and neck region. In order to test the advantage or usefulness of initial chemotherapy followed by radiotherapy (= pre-radiation chemotherapy), the experimental study on combination of chemotherapy and radiotherapy was designed by using ICR mice and Ehrlich solid carcinoma. Cisplatin and peplomycin, a newly developed derivative of bleomycin, were used as chemotherapeutic agents. Tumor growth delay rate was chosen as a parameter to indicate the effectiveness. Results obtained are as follows. 1. Combination chemotherapy of cisplatin and peplomycin was more effective than each single agent on Ehrlich solid carcinoma. Synergistic effect was obtained by higher dose. So, the combination of cisplatin and peplomycin was proved to be eligible for pre-radiation chemotherapy. 2. Synergistic effect of chemotherapy and radiotherapy was observed when chemotherapy was used prior to radiotherapy on Ehrlich solid carcinoma. 3. Even their additional effect was not recognized when radiotherapy preceded to chemotherapy on Ehrlich solid carcinoma. 4. No severe toxic effect was seen in the mice. The experimental results made it clear that pre-radiation chemotherapy is beneficial to the treatment of head and neck cancer. (author)

    The authors reviewed 24 cerebellar medulloblastoma patients treated at Keio University to determine usefulness of combined chemotherapy including platinum derivatives (cisplatin, carboplatin) as the induction and maintenance treatment. All patients underwent radical surgery and craniospinal irradiation. Ten received adjuvant chemotherapy other than platinum derivatives (mainly with nitrosourea compounds), five were treated by induction and maintenance chemotherapy including platinum derivatives, and nine patients did not undergo chemotherapy. The progression-free survival rate of patients treated with platinum derivatives was better than that of patients treated with other modes of chemotherapy and also that of patients who did not receive chemotherapy. The results were especially good in the case of four patients treated with maintenance chemotherapy consisting of carboplatin and etoposide, two of whom had been free from relapse beyond the risk period of Collins. The occurrences of toxicity in maintenance chemotherapy with carboplatin and etoposide were limited to transient leucopenia. The present study indicates combined chemotherapy including platinum derivatives benefits patients with medulloblastoma, and could be useful, especially as maintenance treatment. (author)

  6. Combined chemotherapy and radiotherapy of localized and metastasizing Ewing's sarcoma

    International Nuclear Information System (INIS)

    Between 1973 and 1978 combined radiotherapy and chemotherapy were given to 22 patients with histologically proven Ewing's sarcoma. The combined chemotherapy consisted of cyclophosphamide, vincristin, adriamycin, as well as dacarbazine in some cases. The neoplasm was a localized one at the beginning of treatment in 14 of the 22. These patients received high-voltage rediotherapy to the primary focus at a focal dose between 42 and 55 Gray (4200-5500 rad), followed by chemotherapy. After 6-8 treatment cycles, adriamycin was replaced by methotrexate. Nine of the 14 patients survived without recurrence for 12 to over 59 months. Eight patients had extensive metastases at the beginning of treatment: they at first received only chemotherapy, followed by radiotherapy or operation, as indicated. Full clinical remission was achieved in five of them: in three this remission has now lasted for more than 18, 40 and 44 months, respectively. These results indicate that (1) additional chemotherapy improves the prognosis of localized Ewing's sarcoma, and (2) even in farprogressed cases the combination of chemotherapy and radiotherapy can achieve lasting remission, which may in fact be a true cure.

    Full Text Available BACKGROUND: Intra-arterial (i.a. chemotherapy has more risks of procedural complications in neonates and young infants. For these reasons, we have developed a strategy of bridge intravenous single agent chemotherapy to postpone i.a. chemotherapy in these children PROCEDURE: Neonates and young infants with retinoblastoma who required chemotherapy were treated with systemic carboplatin chemotherapy (18.7 mg/kg i.v. every 3-4 weeks until they reached the age of 3 months and a weight of 6 Kg. If necessary, i.a. chemotherapy was subsequently performed at 4 weeks intervals. Efficacy was judged by tumor regression on ophthalmological examination. Retinal toxicity was judged by electroretinography. RESULTS: Eleven children (19 eyes were treated. All patients are alive and no patient has developed metastatic disease or second malignancies (mean follow-up 27 months, range 9-46 months. Intravenous carboplatin (median 2 cycles, range 1-5 combined with cryotherapy and laser was given to all children. This was effective for five eyes, which did not require i.a. chemotherapy. I.a. chemotherapy was administered to 14 eyes (median 3.5 cycles per eye, range 1 to 6. No radiation therapy was required. The Kaplan Meier estimate of ocular radiation-free survival was 94.7% at one year (95% confidence interval 68.1-99.2%. One eye was enucleated due to tumor progression. ERG showed no deterioration of retinal function. CONCLUSION: Bridge i.v.-i.a. chemotherapy was feasible and safe, and is a promising strategy to treat retinoblastoma in neonates and young infants.

  8. Discovery and Delivery of Synergistic Chemotherapy Drug Combinations to Tumors

    Camacho, Kathryn Militar

    Chemotherapy combinations for cancer treatments harbor immense therapeutic potentials which have largely been untapped. Of all diseases, clinical studies of drug combinations are the most prevalent in oncology, yet their effectiveness is disputable, as complete tumor regressions are rare. Our research has been devoted towards developing delivery vehicles for combinations of chemotherapy drugs which elicit significant tumor reduction yet limit toxicity in healthy tissue. Current administration methods assume that chemotherapy combinations at maximum tolerable doses will provide the greatest therapeutic effect -- a presumption which often leads to unprecedented side effects. Contrary to traditional administration, we have found that drug ratios rather than total cumulative doses govern combination therapeutic efficacy. In this thesis, we have developed nanoparticles to incorporate synergistic ratios of chemotherapy combinations which significantly inhibit cancer cell growth at lower doses than would be required for their single drug counterparts. The advantages of multi-drug incorporation in nano-vehicles are many: improved accumulation in tumor tissue via the enhanced permeation and retention effect, limited uptake in healthy tissue, and controlled exposure of tumor tissue to optimal synergistic drug ratios. To exploit these advantages for polychemotherapy delivery, two prominent nanoparticles were investigated: liposomes and polymer-drug conjugates. Liposomes represent the oldest class of nanoparticles, with high drug loading capacities and excellent biocompatibility. Polymer-drug conjugates offer controlled drug incorporations through reaction stoichiometry, and potentially allow for delivery of precise ratios. Here, we show that both vehicles, when armed with synergistic ratios of chemotherapy drugs, significantly inhibit tumor growth in an aggressive mouse breast carcinoma model. Furthermore, versatile drug incorporation methods investigated here can be broadly

    Antimarial drug resistance develops when spontaneously occurring parasite mutants with reduced susceptibility are selected, and are then transmitted. Drugs for which a single point mutation confers a marked reduction in susceptibility are particularly vulnerable. Low clearance and a shallow concentration-effect relationship increase the chance of selection. Use of combinations of antimalarials that do not share the same resistance mechanisms will reduce the chance of selection because the cha...

    Objective:To explore the clinical efifcacy and safety of rituximab combined with chemotherapy and single chemotherapy for diffuse large B cell lymphoma (DLBCL). Methods:A total of 97 patients with DLBCL were selected. Patients treated by single chemotherapy were designed as control group, while those by rituximab combined with chemotherapy as observational group. All patients were treated for at least 4 cycles. The short-term and long-term efifcacy and related adverse reactions of 2 groups were observed. Results:The rate of complete remission (CR) in observational group was signiifcantly higher than in control group (χ2=4.6589,P=0.0309). However, there was no signiifcant difference in objective remission rate (ORR) between 2 groups (P=0.3651). The rates of 3-year overall survival (OS), progression-free survival (PFS) and disease-free survival (DFS) were 80.30% (53/66), 69.70% (46/66) and 59.09% (39/66) in observational group, and 61.29% (19/31), 58.06% (18/31) and 58.06% (18/31) in control group, respectively. The OS in observational group was signiifcantly longer than in control group (P=0.035). However, there was no signiifcant difference in PFS, DFS and rate adverse reactions between 2 groups (P=0.089;P=0.438;χ2=0.1562,P=0.6927). Conclusion: Rituximab combined with chemotherapy can improve the efficacy of DLBCL without increasing the adverse reactions, which can be used as the ifrst-line treatment for DLBCL, thus deserving to be widely applied in clinic.

    Objective To identify an effective auxiliary therapy for epithelial ovarian cancer. Methods Progesterone acetate given at 250 mg intramuscularly twice a week for 1 month followed by increased administration to 500 mg intramuscularly every two weeks for 3 years was used in combination with platinum based chemotherapy to treat patients with epithelial ovarian cancer as a first-line therapy. Prognoses of the patients receiving progesterone combined with chemotherapy (progesterone group) and those receiving chemotherapy only (control group) were compared. Results Three-year recurrence and survival conditions of the progesterone and control groups were as follows. Stage Ⅰa: no patient relapsed or died in either group. Stage Ⅰb-Ⅰc: three-year recurrence rates were 14.2% and 37.5%, respectively (P=0.2845); three-year survival rates were 92.3% and 87.5% (P=0.7221). Stage Ⅱ: 1 patient relapsed and died among the 3 patients in the progesterone group; among the 4 patients in the control group, 1 patient relapsed, none died. Stage Ⅲ: three-year recurrence rates were 30.8% and 64.3%, respectively (P=0.1170); three-year survival rates were 85.7% and 42.9%, respectively (P=0.005). Stage Ⅳ: 4 patients relapsed and 1 patient died among the 7 patients in the progesterone group; both the patients in the control group relapsed and died. Conclusions The results indicated that progesterone combined with platinum based chemotherapy as a first-line therapy may improve the prognosis of advanced epithelial ovarian cancer, but would not change the prognosis of early stage epithelial ovarian cancer.

    Objective: Chemotherapy is an effective means of treating breast cancer, and cancer-specific replicative adenovirus is also a promising antitumor agent in recent years. Our investigation aims to demonstrate that CNHK300 can mediate selective antitumor efficacy and produce synergistic cytotoxicity with chemotherapy on HER-2 over-expressing breast cancer. Methods: We engineered the telomerase-dependent replicative adenovirus CNHK300 by placing the E1A gene under the control of the human hTERT promoter. By analysis of E1A expression, we proved the fidelity of hTERT promoter in adenovirus genome and the selective expression of E1A in telomerase-positive breast cancer cells but not in normal fibroblast cells. By proliferation test, we further showed efficient replication of CNHK300 in breast cancer cells with apparently attenuated proliferation in normal fibroblast cells. Finally, we demonstrated by MTT methods that CNHK300 virus caused potent cytolysis and produced synergistic cytotoxicity with chemotherapy in breast cancer cells with attenuated cytotoxicity on normal cells. Results: In this virus, the E1A gene is successfully placed under the control of the human hTERT promoter. CNHK300 virus replicated as efficiently as the wild-type adenovirus and caused intensive cell killing in HER-2 over-expressing breast cancer cells in vitro. In contrast, telomerase-negative normal fibroblast cells, which expressed no hTERT activity, were not able to support CNHK300 replication. Combined treatment of CNHK300 with paclitaxel improved cytotoxicity on cancer cells. Conclusion: We conclude that CNHK300 can produce selective antitumor efficacy and enhance the in vitro response of chemotherapy on HER-2 overexpressing breast cancer.

    Given the rarity of follicular lymphoma (FL) in children, there is limited data on which to base treatment recommendations. Herein, we report our institutional experience of using rituximab with multiagent chemotherapy for pediatric FL. Six pediatric patients were diagnosed with FL from 2000 to 2009. All patients received rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) for varying durations. Five of the six patients remain in remission with a median follow-up of 31 months. Larger randomized trials are indicated to establish the efficacy of this regimen for pediatric FL patients.

    vs. ≥6 cm in diameter, p = 0.008), and tumour response after induction chemotherapy and preoperative irradiation (clinically complete response + partial response vs. non-response, p = 0.0015). In the non conservative breast treatment group, of the 32 patients with no change in clinical tumour size after induction chemotherapy, the 10-year metastatic disease-free survival rate was 59% with only one local relapse. Arm lymphedema was noted in 17% (14 of 81) following axillary dissection and in 2.5% (1 of 39) without axillary dissection. Cosmetic results were satisfactory in 70% of patients treated by irradiation alone and in 51.5% of patients after wide excision and irradiation. Conclusion. - Despite the poor prognosis of patients with locally advanced non inflammatory breast cancer resistant to primary anthracycline-based regimen, aggressive locoregional management using preoperative irradiation and mastectomy with axillary dissection offers a possibility of long term survival with low local failure rate for patients without extensive nodal disease. On the other hand, the rate of local failure seems to be high in patients with clinical partial tumour response following induction chemotherapy and breast-conserving treatment combining preoperative irradiation and large wide excision.

Both wild-type and engineered viruses have been selected for targeting of specific cancers, to elicit cytotoxicity, and also to generate antitumor immunity. Single-agent oncolytic virotherapy treatments have resulted in modest effects in the clinic. There is increasing interest in their combination with cytotoxic agents, radiotherapy and immune-checkpoint inhibitors. Similarly to oncolytic viruses, the benefits of chemotherapeutic agents may be that they induce systemic antitumor immunity through the induction of immunogenic cell death of cancer cells. Combining these two treatment modalities has to date resulted in significant potential in vitro and in vivo synergies through various mechanisms without any apparent additional toxicities. Chemotherapy has been and will continue to be integral to the management of advanced cancers. This review therefore focuses on the potential for a number of common cytotoxic agents to be combined with clinically relevant oncolytic viruses. In many cases, this combined approach has already advanced to the clinical trial arena. Keywords: oncolytic virotherapy, chemotherapy, immunogenic cell death

    The authors report the results of a prospective, multi-centre trial involving 87 patients with previously untreated myeloma who were treated by combination chemotherapy consisting of melphalan, cyclophosphamide, CCNU, prednisone and vincristine. 83.1% of patients had a high tumour mass (stage III on Durie and Salmon's classification). The response to treatment could be evaluated in 76 patients and 70% were found to respond. The median actuarial survival of the whole population is 30 months. The survival is significantly longer (p less than 0.001) in responders (median 40 months) than in non-responders (median: 17 months); the survival is significantly shorter (p less than 0.01) in subjects with renal failure (median: 10 months) than in subjects without renal failure (median: 36 months). This treatment is sufficiently well tolerated to be administered on an outpatient basis. One case of acute monoblastic leukaemia was observed. These results are similar to those reported in the literature. PMID:6740189

  2. Combination chemotherapy (COMP protocol) and radiotherapy of anaplastic supratentorial gliomas

    International Nuclear Information System (INIS)

    Postoperative survival time and recurrence-free intervals in 116 consecutive patients with supratentorial grade III and IV gliomas (glioblastomas, gliosarcomas, anaplastic astrocytomas, and ependymomas) were compared in unselected groups receiving different forms of treatment. Postoperative high-voltage radiotherapy (31 patients, dosage 4,000-6,000 rads) and combined chemotherapy consisting of CCNU, vincristine, amethopterine, and procarbazine in 15-day circles (COMP protocol) (12 patients) showed the same median survival time of 10.6 months and comparable recurrence-free intervals of 6.8 and 7.0 months, respectively. These results were significantly different from a control group (39 patients) receiving best postoperative supportive (conventional) care (median survival 5.4 months, free interval 3.7 months). Combination of postoperative radiotherapy with simultaneous polychemotherapy (COMP protocol), evaluated in 18 patients, did not significantly change the recurrence-free interval (median 7.0 months), but increased the median survival time to 12.9 months, which was significantly superior to the two other treatment groups. The toxic side effects of COMP therapy were moderate and essentially haematological. In general, simultaneous radiation and chemical treatment was well tolerated after major tumour resection. These preliminary results of postoperative combination of radiation and polychemotherapy for anaplastic supratentorial gliomas appear encouraging, but further trials for optimization of combined therapeutic strategies are warranted.

  3. Multimodal treatment combining chemotherapy, hyperthermia and radiotherapy for ovarian cancer

    International Nuclear Information System (INIS)

    There has been increasing interest in the use of heat in the treatment of cancer. Theoretically cells are the most sensitive to ionizing radiation at mitosis, whereas the cycle phase that is the most resistant to ionizing radiation namely late in the DNA. Synthetic phase (late S) is the most sensitive to hyperthermia. Hyperthermia has been reported to enhance the cytocidal effects of several active chemotherapeutic agents. When thermal potentiation of chemotherapeutic agents against malignant cells is contemplated, normal tissues have a relatively high ambient blood flow which increases in response to thermal stress, thereby dissipating heat, compared to tumors. Tumors, with relatively poor blood flow and a responsive neovasculature, are in capable of augmenting flow and acting as a heat reservoir. This is the phenomenon of a heat reservoir which is one factor to enhance the cytocidal effects of several active anticancer agents for enhancing the uptake in tumor. The importance is in the adjuvant chemotherapy treated for post operative, advanced and recurrent ovarian cancer. Heating enhances the effects of radiotherapy and chemotherapy. Thirty patients with ovarian cancer were subjected to the multidisciplinary treatment with combination of hyperthermochemotherapy and radiation. The 30 patients consisted of 18 with endometrioid adenocarcinoma and 7 with serious post operative or recurrent status. Two types of equipments with rediofrequencies of 70 MHz (BSD-1000) or 434 MHZ (TAG MED·HS 434) were used for hyperthermia. Chemotherapeutic agents such as adriamycin, cis DDP, cyclophosphamide and etoposide were injected intravenously. Arterial infusion with reservoir was very effective in advanced stage of ovarian cancer. No severe or fatal side effects were observed. Hyperthermochemotherapy is useful and effective for the postoperative management or the treatment of recurrent cancer of the ovary. (J.P.N.)

  4. Combined radiotherapy and chemotherapy for high-grade brain tumours

    Science.gov (United States)

    Barazzuol, Lara

    Glioblastoma (GBM) is the most common primary brain tumour in adults and among the most aggressive of all tumours. For several decades, the standard care of GBM was surgical resection followed by radiotherapy alone. In 2005, a landmark phase III clinical trial coordinated by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) demonstrated the benefit of radiotherapy with concomitant and adjuvant temozolomide (TMZ) chemotherapy. With TMZ, the median life expectancy in optimally managed patients is still only 12-14 months, with only 25% surviving 24 months. There is an urgent need for new therapies in particular in those patients whose tumour has an unmethylated methylguanine methyltransferase gene (MGMT) promoter, which is a predictive factor of benefit from TMZ. In this dissertation, the nature of the interaction between TMZ and radiation is investigated using both a mathematical model, based on in vivo population statistics of survival, and in vitro experimentation on a panel of human GBM cell lines. The results show that TMZ has an additive effect in vitro and that the population-based model may be insufficient in predicting TMZ response. The combination of TMZ with particle therapy is also investigated. Very little preclinical data exists on the effects of charged particles on GBM cell lines as well as on the concomitant application of chemotherapy. In this study, human GBM cells are exposed to 3 MeV protons and 6 MeV alpha particles in concomitance with TMZ. The results suggest that the radiation quality does not affect the nature of the interaction between TMZ and radiation, showing reproducible additive cytotoxicity. Since TMZ and radiation cause DNA damage in cancer cells, there has been increased attention to the use of poly(ADP-ribose) polymerase (PARP) inhibitors. PARP is a family of enzymes that play a key role in the repair of DNA breaks. In this study, a novel PARP inhibitor, ABT-888

    International Nuclear Information System (INIS)

    Objective: To evaluate super-selective interventional chemotherapy combined with systemic chemotherapy in treating postoperative gliomas. Methods: During the period of 2005-2009, a total of 46 patients with glioma were encountered in our hospital. According to the principle of patient's free will the involved patients were divided into two groups. Study group (n = 25): after operation the patients received routine radiotherapy, which was followed by super-selective interventional chemotherapy combined simultaneously with systemic chemotherapy. Control group (n = 21): after operation the patients received routine radiotherapy, which was followed by systemic chemotherapy only. The patients were regularly followed up. Cranial CT checkups were made to determine the tumor size, and the results were evaluated with Karnofsky scores. The clinical data were analyzed and compared between two groups. Results: In the study group, the side-effects and complications included epileptic seizures (n = 3), eye pain (n = 5), headache (n = 9), nausea and vomiting (n = 8) and thrombopenia (n = 1). In the control group,the side-effects and complications were as follows: epileptic seizures (n = 1), headache (n = 7), nausea and vomiting (n = 6) and thrombopenia(n = 3). No death occurred in either of the two groups. The patients were followed up for an average period of 2.3 years. Before chemotherapy no statistically significant difference in tumor size existed between two groups (P > 0.05). One year after the chemotherapy, the tumor volume in study group was reduced by 67.11%, while it was 45.79% in control group. By using independent sample t test analysis, the difference between two groups was of statistical significance (P < 0.05). Wilcoxon rank sum test and Karnofsky prognostic score analysis indicated that the prognosis of study group was much better than that of control group (P < 0.05). Conclusion: In comparison with routine radiotherapy plus simple systemic chemotherapy, routine

    2007-01-01

    Objective To evaluate the anti-tumor effect and toxicity of gemcitabine combined with platinum chemotherapy on recurrent epithelial ovarian cancer.Methods Phase Ⅱ study of gemcitabine combined with platinum chemotherapy was carried out in 22 patients with recurrent epithelial ovarian cancer. Median age of patients was 50. 5 years old. Seven patients were platinum-sensitive and 15 patients were platinum-resistant or -refractor. All patients received gemcitabine combined with carboplatin or oxaliplatin chemotherapy. Patients' response rate (RR) and toxicity of gemcitabine combined with platinum chemotherapy were evaluated.Results A total of 98 gemcitabine-based chemotherapy cycles were performed. Total RR was 36.4%, RR of platinum-sensitive patients was 4/7 and platinum-resistant and -refractory patients was 4/15. The estimated median survival time was 10. 0 months (95% CI: 7.0-13.0) after initiation of gemcitabine combined with platinum chemotherapy.There was no significant difference in survival time between platinum-resistant/refractory group and platinum-sensitive group (P = 0. 061 ). Side effects of gemcitabine combined with platinum chemotherapy were observed in 81.8 % of patients. Grade Ⅱ/Ⅲ anemia (54.5%) and grade Ⅲ/Ⅳ neutropenia (54.5%) were most common toxicities. Ten (45.5%) patients had to delay their chemotherapy cycles or reduce the dose of chemotherapeutic drugs because of the severe side effects. Fourteen (63.6%) patients received granulocyte colony-stimulating factor to relieve neutropenia,and 8 (36. 4% ) patients received component blood transfusion to treat anemia or thrombocytopenia. There was no treatment-associated death.Conclusion Gemcitabine combined with platinum chemotherapy appears to be an effective and well-tolerant treatment for recurrent epithelial ovarian cancer, including platinum-resistant or -refractory diseases.

    Full Text Available Introduction: Angiogenesis plays an important role in the biology of ovarian cancer. The clinical efficacy and side effects of bevacizumab, the vascular endothelial growth factor inhibitor, on survival and toxicity in women with this ovarian cancer, was not conclusive. We performed this systematic review and meta-analysis in order to clarify the efficacy of bevacizumab combined with chemotherapy in the treatment of ovarian cancer. Materials and Methods: We searched the electronic database of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and CNKI for clinical controlled trials of comparing bevacizumab combined with chemotherapy and chemotherapy alone in the treatment of ovarian cancer. The primary outcomes of eligible studies included median progression-free survival (PFS, overall survival (OS, and toxicities such as enterobrosis, hypertension, albuminuria, congestive heart failure (CHF, neutrophils, thrombosis, and bleeding. The Hazard ratio (HR and relative risk were used for the meta-analysis and were expressed with 95% confidence intervals (CIs. All the statistical analyses were carried out by  Stata 11.0 software (http://www.stata.com; Stata Corporation, College Station, TX, USA. Results: We included 5 studies with 1798 cases in the bevacizumab combined with the chemotherapy group and 1810 subjects in the chemotherapy alone group. The pooled results showed that bevacizumab + chemotherapy compared with chemotherapy alone can significant prolong the median PFS (HR, 0.64; 95% CI, 0.46-0.82; P 0.05; the toxicity analysis showed that the enterobrosis, hypertension, albuminuria, neutrophils, thrombosis, and bleeding were significantly increased in the bevacizumab + chemotherapy group compared with chemotherapy alone (Pall 0.05. Conclusion: Bevacizumab combined with chemotherapy prolonged the median PFS in patients with ovarian cancer but also increase the risk of developing enterobrosis, hypertension, albuminuria, neutrophils

    Clofarabine, one of the key treatment agents for refractory and relapsed acute lymphoblastic leukemia (ALL), achieves a remission rate of approximately 30% with single-agent clofarabine induction chemotherapy. However, a remission rate of approximately 50% was reported with a combination chemotherapy regimen consisting of clofarabine, etoposide, and cyclophosphamide. We treated two cases with refractory and relapsed ALL with combination chemotherapy including clofarabine; one was an induction failure but the other achieved remission. Both cases developed an infectious complication (NCI-CTCAE grade 3) and body pain with infusion. Prophylactic antibiotic and opioid infusions facilitated avoiding septic shock and pain. Further investigation of such cases is required. PMID:25501414

  16. Combined therapy of radiotherapy and chemotherapy on brain tumor

    International Nuclear Information System (INIS)

    The subjects were 52 patients (5-78 years, average 51.4 years) with primary brain tumor treated in 4 institutes in Chugoku and Shikoku districts during 3 years from April 1991. Histopathologically, the subject diseases were glioblastoma in 16, well differentiated glioblastoma in 19, brain primary lymphoma in 9, and malignant meningioma in 5. In the glioblastoma group, 14 received surgery, radiotherapy, and chemotherapy at the first admission. Three patients who survived more than 1 year and 6 patients who died within 1 year were compared. No significant difference was observed in terms of radiotherapy between the both groups. In the astrocytoma and oligodendroglioma groups, 16 patients received radiotherapy and chemotherapy as the initial treatment, and 14 underwent several course of maintenance therapy. In the comparison between 7 patients who died within 3 years from the first treatment and 9 patients surviving more than 3 years, no significant difference was observed in terms of radiation doses.

  17. Combined modality treatment of chemotherapy and thoracic radiotherapy for limited-stage small cell lung cancer

    International Nuclear Information System (INIS)

    Small cell lung cancer (SCLC) differs from other types of lung cancer in its more aggressive clinical course and superior responsiveness to chemo- and radiotherapy. Median survival of patients with unresectable limited disease was reported only 3 months by supportive care alone. SCLC was treated by surgery in 1950s, but results were disappointing. In a British study in the 1960s, radiotherapy proved superior to surgery in survival. However, most patients treated with thoracic radiotherapy alone died of instant metastases with median survival of 5-9 months, indicating a need for primary systemic treatment. In the 1970s, combined chemotherapy came to be the main treatment for SCLC; high response rate and improved survival led to the idea that thoracic radiotherapy added only toxicities with no therapeutic advantage in chemotherapy-treated patients. Considering the fact that 80% of patients treated with chemotherapy alone relapsed in primary sites, and that radio-therapy achieved response in 90% of limited disease patients, it is reasonable to attempt to combine systemic chemotherapy and thoracic radio-therapy to improve therapeutic results for this disease. In 1980s, several randomized trials comparing chemotherapy alone versus chemotherapy with thoracic radiotherapy were conducted to clarify the role of thoracic radio-therapy in combination with chemotherapy for limited SCLC.

    2015-01-01

    As a targeted therapy, antiangiogenic treatment has been increasingly studied for advanced non-smal cel lung cancer (NSCLC) and has proven ef ective for the treatment of advanced NSCLC. Bevacizumab, a monoclonal antibody targeting angiogenesis, is the only antiangiogenic agent approved for use in com-bination with first-line chemotherapy for non-squamous NSCLC. Smal-molecule inhibitors targeting the tyrosine kinase receptor have also shown promise when combined with standard chemotherapeutic agents in patients with advanced NSCLC. However, unlike bevacizumab, not al other antiangiogenic agents show significant benefits when combined with chemotherapy. As for the failures of most other combinations, the combination schedule may be an important reason that has so far been overlooked in clinical trials. This article reviews the combination of angiogenic agents with chemotherapy in the treatment of NSCLC.

  19. Malignant cliomas treated after surgery by combination chemotherapy and delayed irradiation. Pt. 1

    International Nuclear Information System (INIS)

    Forty-six patients with gliomas were introduced after surgery into a therapeutic programme of six cycles of combination chemotherapy with VM26 and CCNU, followed by delayed irradiation six months after surgery with an average dose of 5,800 rads. After irradiation the same preradiation chemotherapy was readministered for an average of four cycles. The results were compared to those from another group of 28 patients treated only by the same chemotherapy (CRC and C groups successively). Twelve patients (26%) died before irradiation in the CRC groups, six patients (13%) had recurrences at the time of irradiation, and 28 patients (61%) had no clinical or radiological signs of recurrence at the time of irradiation. For the total of treated patients the median survival after surgery was 17 months, and 46% of the patients were surviving at 18 months. The percentage of survivors at 18 months was significantly more elevated in the group treated by combination chemotherapy and delayed irradiation than in a control group treated by the same combination chemotherapy alone. This result suggests that in approximately 50% of cases combination chemotherapy after surgery, and delayed irradiation six months after surgery, cumulated their effects on survival time. (author)

  1. An exceptional case of myelodysplastic syndrome with myelofibrosis following combination chemotherapy for squamous cell lung cancer

    International Nuclear Information System (INIS)

    A 60-year-old woman with squamous cell carcinoma in the right lung was successfully treated with four cycles of combination chemotherapy after surgery, and complete remission was achieved. However, the patient developed myelodysplastic syndrome (MDS) RAEB-2 with myelofibrosis after remission, possibly because of chemotherapy or DNA methylation. The patient responded well to dacitabine (Dacogen), suggesting that DNA hypomethylation agents can be a promising therapy to retard the progression of a second tumor or carcinoma

    It has been found that preoperative plasma IGFBP-2 levels correlate with prognosis in glioma patients. The prognostic value of plasma IGFBP-2 after postoperative combined radiotherapy and chemotherapy in glioma patients is unknown. Plasma IGFBP-2 levels in 83 glioblastoma patients after postoperative radiotherapy plus chemotherapy were analyzed using an IGFBP-2 ELISA kit. We found that after standard therapy plasma IGFBP-2 levels significantly correlated with the patient's age (R = 0.738, P

    Our early observations have confirmed that laser hyperthermia or PDT alone does not promote the tumor metastasis. In order to evaluate the combined effect of local tumor laser hyperthermia on the distant metastasis, transplantable forestomach carcinoma (Fc) in 615 line mice was treated by Nd:YAG laser hyperthermia (45 degree(s)C/20 min) combined with PDT (HpD 5 mg/kg, 480 J/cm2, 20 min), chemotherapy (Cyclophosphamide 28.8 mg/kg) and excision, respectively. The results show that (1) the tumor growth inhibition by various treatment was significant compared with a control group; (2) no statistics different in metastasis rate were observed in laser hyperthermia combined with PDT, chemotherapy, or scalpel excision separately. It is suggested that laser hyperthermia combined with PDT, chemotherapy, or excision does not increase the incidence of the tumor metastasis.

    Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy. Doxorubicin (DOX) was encapsulated in MNP-PMs, and an alternating magnetic field (AMF) resulted in an increase to temperature within a suitable range for inducing hyperthermia and a higher rate of drug release than observed without AMF. In vitro cytotoxicity and hyperthermia experiments were carried out using human lung adenocarcinoma A549 cells. When MNP-PMs encapsulated with an anticancer drug were used to treat A549 cells in combination with hyperthermia under AMF, 78% of the cells were killed by the double effects of heat and the drug, and the combination was more effective than either chemotherapy or hyperthermia treatment alone. Therefore, MNP-PMs encapsulated with an anticancer drug show potential for combined chemotherapy and hyperthermia.Magnetic nanoparticle-conjugated polymeric micelles (MNP-PMs) consisting of poly(ethylene glycol)-poly(lactide) (PEG-PLA) and iron oxide nanoparticles were prepared and used as nanocarriers for combined hyperthermia and chemotherapy.

  5. Treatment of non-Hodgkin's lymphoma of Waldeyer's ring: radiotherapy versus chemotherapy versus combined therapy

    International Nuclear Information System (INIS)

    Treatment of stage IA non-Hodgkin's lymphoma (NHL) of Waldeyer's ring remains controversial, probably because of the small number of patients and the scarcity of controlled studies. Between 1981 and 1991, 316 patients with stage I NHL of Waldeyer's ring were randomised for treatment with radiotherapy alone (extended fields), 101 patients; combined chemotherapy with a regimen of CHOP (cyclophosphamide, vincristine, doxorubicin, and prednisone) or CHOP-like (epirubicin instead of doxorubicin), 106 patients; and combined therapy (radiotherapy followed by the same combination chemotherapy), 109 patients. Median follow-up was 6.8 years. Complete response was achieved in 93, 87 and 97%, respectively. Relapses were least frequent in patients treated with combination therapy. The 5-year rate for failure-free survival was 48% for radiation therapy, 45% for the patients who were treated with chemotherapy, which was statistically significantly less than the 83% for patients treated with combined therapy (P < 0.001). Overall survival was also better in the combined therapy arm: 90%, statistically different to 58% for the patients treated with chemotherapy alone and 56% for patients treated with radiation therapy (P < 0.001). Toxicity was mild and late side-effects were not observed in any patients. From these results combined therapy should be considered as the best therapeutic approach in patients with localised NHL of Waldeyer's ring. (author)

    This study was to evaluate effect of 125I brachytherapy combined with chemotherapy on advanced non-small cell lung cancer (NSCLC). Patients with NSCLC in stages III to IV were divided into two groups: Group A (n = 27) received 125I brachytherapy combined with gemcitabine and cisplatin (GP) chemotherapy, and Group B (n = 27) received GP chemotherapy only. The results showed that the overall response rate and median progression-free survival time were 78%and 11.5 months in Group A, 41%and 8 months in Group B, respectively (P 0.05). The interventional complications in Group A included 5 patients with postoperative pneumothorax and 4 patients with hemoptysis. No patients had radiation pneumonia, radiation esophagitis or esophagotracheal fistula. Chemotherapy treatment-related toxicities were not significantly different between the two groups. The relief of tumor-associated symptoms including cough, hemoptysis, chest pain, and short breath was found in both groups, without statistical difference in remission rates between Groups A and B (P >0.05). In conclusion, 125I brachytherapy combined with chemotherapy proved to be safe and effective for treating advanced NSCLC with few complications. It improves local control rate and prolongs the progression-free survival time.

  7. Long term survival with the combination of interferon and chemotherapy in metastatic melanoma

    International Nuclear Information System (INIS)

    The prognosis of metastatic melanoma is poor. Pre-targeted treatment era, the combination of interferon-α (IF-α) plus chemotherapy had been used and have generally short response duration. Herein, we present a metastatic melanoma case that achieved long-term durable complete response (CR) IF-α plus chemotherapy and IF-α maintenance therapy and had lower Regulatory T (Treg) cells. A fifty-year old woman was admitted to the hospital with metastatic melanoma. Lactate dehydrogenase (LDH) level was 660 U/L. The percentage of CD4+CD25+ Treg cells was 2.4% in CD4+ lymphocytes. The IF-α plus chemotherapy and IF-α maintenance were administered. After six courses of chemotherapy, CR was achieved. Vitiligo and hypothyroidism occurred. The patient has remained in CR for approximately 7 years until second pleural metastases were detected and death. The patient has positive prognostic factors such as induction of auto immunity, small tumor volume, mild elevated LDH level, and lower Treg cell percentage. She survived long term with CR after IF-α treatment with concurrent chemotherapy and maintenance. IF-α plus chemotherapy may be a treatment option for metastatic melanoma in selected cases who cannot reach new targeted drugs

  8. Combination chemotherapy for advanced diffuse non-Hodgkin's lymphomas in relapse following local radiotherapy

    International Nuclear Information System (INIS)

    Eleven patients with advanced diffuse non-Ho-dgkin's lymphoma arising from head and neck in relapse following local radiotherapy were treated with C-MOPP or Adriamycin-based combination chemotherapy. Eight patients had diffuse lymphoma of large cell type, two diffuse lymphoma of medium-sized cell type and one pleomorphic type of lymphoma. Complete remission was obtained in 8 of 11 patients (72.7 %). Three of these had relapsed within two years after completion of combination chemotherapy; all of three expired at 27 months, 41 months and 48 months, respectively. On the other hand, three patients whose complete remission lasted beyond two years still survive 46 months, 48 months, and 66 months without recurrence. The main side-effects during induction chemotherapy was bone marrow suppression and its related infections. (author)

    Here we evaluate the current status of clinical research on regional hyperthermia (RHT) in combination with chemotherapy or radiation therapy in paediatric oncology.Data were identified in searches of MEDLINE, Current Contents, PubMed, and references from relevant articles using medical subject headings including hyperthermia, cancer, paediatric oncology, children, radiation therapy and chemotherapy. Currently, only two RHT centres exist in Europe which treat children. Clinical RHT research in paediatric oncology has as yet been limited to children with sarcomas and germ cell tumours that respond poorly to or recur after chemotherapy. RHT is a safe and effective treatment delivering local thermic effects, which may also stimulate immunological processes via heat-shock protein reactions. RHT is used chiefly in children and adolescents with sarcomas or germ cell tumours located in the abdomino-pelvic region, chest wall or extremities to improve operability or render the tumour operable. It could potentially be combined with radiation therapy in a post-operative R1 setting where more radical surgery is not possible or combined with chemotherapy instead of radiation therapy in cases where the necessary radiation dose is impossible to achieve or would have mutilating consequences. RHT might also be an option for chemotherapy intensification in the neoadjuvant first-line treatment setting for children and adolescents, as was recently reflected in the promising long-term outcome data in adults with high-risk soft tissue sarcomas (EORTC 62961/ESHO trial).The limited data available indicate that combining RHT with chemotherapy is a promising option to treat germ cell tumours and, potentially, sarcomas. RHT may also be beneficial in first-line therapy in children, adolescents and young adults. The research should focus on optimising necessary technical demands and then initiate several clinical trials incorporating RHT into interdisciplinary treatment of children

    The loss-of-function mutation of formyl peptide receptor 1 (FPR1) has a negative impact on the progression-free and overall survival of breast cancer patients treated with anthracycline-based adjuvant chemotherapy. This effect may be attributed to the fact that chemotherapy-induced antitumor immunity requires FPR1 and that such anticancer immune responses are responsible for the long-term effects of chemotherapy. Here, we investigated the possible contribution of FPR1 to the efficacy of a combination of mitoxantrone (MTX) and cyclophosphamide (CTX) for the treatment of hormone-induced breast cancer. Breast cancer induced by a combination of medroxyprogesterone acetate (MPA) and 7,12-Dimethylbenz[a]anthracene (DMBA) could be successfully treated with MTX plus CTX in thus far that tumor growth was retarded and overall survival was extended (as compared to vehicle-only treated controls). However, the therapeutic efficacy of the combination therapy was completely abolished when FPR1 receptors were blocked by means of cyclosporin H (CsH). Future genetic studies on neoadjuvant chemotherapy-treated breast cancers are warranted to validate these findings at the clinical level. PMID:27471610

    2016-07-01

    Chemotherapeutic regimens are the most common treatment to inhibit tumor growth, but there is great variability in clinical responses of cancer patients; cancer cells often develop resistance to chemotherapeutics which results in tumor recurrence and further progression. Metformin, an extensively prescribed and well-tolerated first-line therapeutic drug for type 2 diabetes mellitus, has recently been identified as a potential and attractive anticancer adjuvant drug combined with chemotherapeutic drugs to improve treatment efficacy and lower doses. In this review, we summarized the molecular mechanisms underlying anticancer effects of metformin, which included insulin- and AMPK-dependent effects, selectively targeting cancer stem cells, reversing multidrug resistance, inhibition of the tumor metastasis and described the antineoplastic effects of metformin combined with chemotherapeutic agents in digestive system cancers (colorectal, gastric, hepatic and pancreatic cancer), reproductive system cancers (ovarian and endometrial cancer), prostate cancer, breast cancer, lung cancer, etc. Moreover, the clinical trials regarding metformin in combination of chemotherapeutic drugs were presented and the clinical obstacle or limitation related to the potential role of metformin in cancer treatment was also discussed in this review.

The target of these antineoplastic agents is nuclear DNA, although it is not restricted to malignant cells. The aim of the present study was to assess DNA damage in peripheral blood lymphocytes (PBLs) of breast cancer patients subjected to combined adjuvant chemotherapy (5-fluorouracil, epirubicin and cyclophosphamide, FEC), using a modified comet assay to detect DNA single-strand breaks (SSB) and double-strand breaks (DSB). Forty-one female patients with advanced breast cancer before and after chemotherapy and 60 healthy females participated in the study. Alkaline and neutral comet assays were performed in PBLs according to a standard protocol, and DNA tail moment was measured by a computer-based image analysis system. Breast cancer patients before treatment had higher increased background levels of SSB and DSB as compared to healthy women. During treatment, a significant increase in DNA damage was observed after the 2nd cycle, which persisted until the end of treatment. Eighty days after the end of treatment the percentage of PBLs with SSB and DSB remained elevated, but the magnitude of DNA damage (tail moment) returned to baseline levels. There was no correlation between PBL DNA damage and response to chemotherapy. DNA-SSB and DSB in PBLs are present in cancer patients before treatment and increase significantly after combined chemotherapy. No correlation with response to adjuvant chemotherapy was found. Biomonitoring DNA damage in PBLs of cancer patients could help prevent secondary effects and the potential risks of developing secondary cancers

    The development of reactive oxygen species (ROS)-responsive drug delivery and drug release has gradually attracted much attention in recent years as a promising therapeutic strategy. Singlet oxygen ((1)O2) as the major ROS species is widely used in photodynamic therapy (PDT) of cancer. In the present study, we introduce a combined treatment using ROS-sensitive thioketal (TK) linkage as a linker between upconversion nanoparticles (UNs)-based PDT and doxorubicin (DOX)-based chemotherapy. UNs can not only play a role in PDT, but can also be used as a nanocarrier for drug delivery of DOX. Moreover, the products of (1)O2 during PDT are able to cleave TK linker inducing the release of DOX which can further achieve the goal of chemotherapy. By using this (1)O2-responsive nanocarrier delivery system, DOX can easily reach the tumor site and be accumulated in the nuclei to effectively kill the cancer cells, and therefore decreasing the side effects of chemotherapy on the body. Thus, PDT also has the function of controlling drug release in this combination treatment strategy. Compared with monotherapy, the combination of PDT with chemotherapy also possesses excellent drug loading capability and anticancer efficiency. PMID:27443831

    Objective: To observe the efficacy and safety of cetuximab combined with chemotherapy in advanced non-small-cell lung cancer (NSCLC), and to investigate the association of status of K-RAS gene mutation and epidermal growth factor receptor (EGFR) genotype with clinical outcome.Methods: Between Jan. 2006 and Sep. 2009, nineteen patients with advanced NSCLC received cetuximab (≥4 weeks) combined with chemotherapy in Department of Thoracic Oncology at Beijing Cancer Hospital. Response, survival and toxicity were retrospectively assessed, epidermal growth factor receptor (EGFR) protein expression was evaluated by ELISA Kit. The status of K-RAS gene mutation was tested by PCR-RFLP and EGFR gene amplification was measured by EGFR fluorescence in situ hybridization (FISH).Results: Partial response(PR) was observed in 26.3%(5/19) of the patients and stable disease(SD) in 52.6%(10/19). Median progression free survival(PFS) was 6 months (95% CI: 3.6-8.4). Median overall survival (MST) and 1-year survival rate(SR) were 10.6 months (95% CI: 6.6-14.6) and 47.6%, respectively. Mild or moderate skin rash was the most common toxicity related with cetuximab. K-RAS gene mutation, EGFR protein level and amplification have little correlation with prognosis.Conclusion: Cetuximab combined with chemotherapy was tolerable and the skin rash related with cetuximab was mild to moderate. Cetuximab may prolong survival of the patients who failed to previous chemotherapy.

  2. Combined chemotherapy and radiation therapy in limited disease small-cell lung cancer

    International Nuclear Information System (INIS)

    This is a retrospective study to evaluate the response rate, acute toxicity, and survival rate of a combined chemotherapy and radiation therapy in limited disease small cell lung cancer. Forty six patients with limited disease small-cell lung cancer who underwent combined chemotherapy and radiation therapy between October 1994 and April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP regimen (etoposide, ifosfamide, and cis-platin) or a EP regimen (etoposide and cis-platin). Thoracic radiation therapy was planned to deliver 44 Gy using 10MV X-ray, starting concurrently with chemotherapy. Response was evaluated 4 weeks after the completion of the planned chemotherapy and radiation therapy, and the prophylactic cranial irradiation was planned only for the patients with complete responses. Acute toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and disease-free survival were calculated using the Kaplan-Meier Method. The median follow-up period was 16 months (range:2 to 41 months). Complete response was achieved in 30 (65%) patients, of which 22 patients received prophylactic cranial irradiations. Acute toxicities over grade III were granulocytopenia in 23 (50%), anemia in 17 (37%), thrombo-cytopenia in nine (20%), alopecia in nine (20%), nausea/vomiting in five (11%), and peripheral neuropathy in one (2%). Chemotherapy was delayed in one patient, and the chemotherapy doses were reduced in 58 (24%) out of the total 246 cycles. No radiation esophagitis over grade III was observed, while interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The local recurrences were observed in 8 patients and local progressions were in 6 patients, and the distant metastases in 17 patients. Among these, four patients had both the local relapse and the distant metastasis. Brain was the most common metastatic site (10 patients), followed by the liver as the next common site (4 patients).

    The combination of magnetic hyperthermia therapy with the controlled release of chemotherapeutic agents in tumors may be an efficient therapeutic with few side effects because the bioavailability, tolerance and amount of the drug can be optimized. Here, we prepared magnetoliposomes consisting of magnetite nanoparticle cores and the anticancer drug gemcitabine encapsulated by a phospholipid bilayer. The potential of these magnetoliposomes for controlled drug release and cancer treatment via hyperthermic behavior was investigated. The magnetic nanoparticle encapsulation efficiency was dependent on the initial amount of magnetite nanoparticles present at the encapsulation stage; the best formulation was 66%. We chose this formulation to characterize the physicochemical properties of the magnetoliposomes and to encapsulate gemcitabine. The mean particle size and distribution were determined by dynamic light scattering (DLS), and the zeta potential was measured. The magnetoliposome formulations all had acceptable characteristics for systemic administration, with a mean size of approximately 150 nm and a polydispersity index <0.2. The magnetoliposomes were stable in aqueous suspension for at least one week, as determined by DLS. Temperature increases due to the dissipation energy of magnetoliposome suspensions subjected to an applied alternating magnetic field (AMF) were measured at different magnetic field intensities, and the values were appropriated for cancer treatments. The drug release profile at 37 °C showed that 17% of the gemcitabine was released after 72 h. Drug release from magnetoliposomes exposed to an AMF for 5 min reached 70%.

  6. Neuropsychological evaluation of patients with inoperable non-small cell lung cancer treated with combination chemotherapy or radiotherapy

    International Nuclear Information System (INIS)

    Neuropsychological tests were used to evaluate possible central nervous system dysfunction in patients treated with chemotherapy. Ninety-five patients with non-small cell lung cancer limited disease were randomized to either radiotherapy (2.8 Gyx15) or combination chemotherapy with cisplatin and etoposide. In order to evaluate cognitive functions three neuropsychological tests were applied: Trail Making, Benton Visual Retention Test and Verbal Learning. Changes in the patients' test scores before and after treatment were compared. The chemotherapy patients showed reduced performance on some of the neuropsychological tests compared to the radiotherapy group. This indicates a treatment related effect on the central nervous system, possibly caused by the combination chemotherapy. (orig.)

    The effects of a therapeutic course of the combination of carboplatin and etoposide on platelet function have been evaluated in 10 pediatric patients with brain tumors. Platelet count, in vitro aggregation tests, P-selectin expression and agonist-induced ATP release were evaluated before, and 7 and 15 days after one cycle of chemotherapy. The analysis of the results demonstrated the presence of an in vitro platelet aggregation defect in response to collagen and arachidonic acid in all patients 7 days after therapy. A concomitant decrease of collagen- and arachidonic acid-induced ATP release was also observed. Both platelet aggregation and ATP release returned to baseline values 15 days after chemotherapy administration. Conversely, in vitro platelet aggregation and secretion induced by ADP and epinephrine were unaltered by carboplatin and etoposide administration. Furthermore, P-selectin expression was negative at baseline and did not change after chemotherapy. These results support the hypothesis that combination etoposide and carboplatin chemotherapy in pediatric patients is responsible for possible disturbances in biochemical pathways required for platelet secretion and aggregation.

    Objective: To compare the effect of hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group A, 65 patients) with conventional fractionation radiation combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group B, 65 patients) for unresectable primary liver cancer. Methods: A total to 130 stage II primary liver patients confirmed by pathology and evaluated as unresectable by exploratory laparotomy were divided evenly into group A and group B by the sequence of exploration. The two groups were comparable in age, sex, tumor type and positive fetal protein (AFP). Group A patients were treated by hepatic artery chemotherapy (PDD, 10 mg/day) 6 day a week with hepatic artery ligation followed by hyperfractionation radiotherapy (250 cGy/f, bid) 3 days a week with the scheme alternated weekly. Group B patients were treated by conventional fractionation radiotherapy with the same scheme of chemotherapy as group A. The total dose of PDD and radiotherapy for both groups were 240 mg and 45 Gy. Results: The AFP level was reduced to half in 89.7% of patients in group A and 67.6% in group B. The 1-, 3- and 5-year survival rates were 90.8%, 63.1%, 23.1% for group A and 73.9%, 41.5%, 9.2% for group B, the difference was statistically significant (P 0.05). Conclusions: Hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation is an effective and reasonable therapeutic scheme for unresectable liver cancer. It can effectively relieve symptoms, reduce the tumor, increase second surgical resection rate and prolong the survival. At the same time, the operation is simple and relatively easy

    1997-01-01

    To investigate the increased nephrotoxicity of taxol and cisplatin combination chemotherapy in gynecologic cancers as compared to cisplatin alone, the medical records of 25 patients with gynecological cancers were reviewed for evaluation of nephrotoxicity after chemotherapy treatment. The data included age, serum creatinine, calculated creatinine clearance, initial and cumulative dose of cisplatin and taxol, primary site of the cancer, renal ultrasound and hydration protocols. Renal function was evaluated before, during and 6 months after chemotherapy. Renal dysfunction was defined as a greater than 25% decrease in creatinine clearance. Comparing 11 patients treated with taxol and cisplatin versus 14 treated with cisplatin alone, there was a significant difference in effect on renal function. Nine of 11 patients (81%) treated with the combination chemotherapy had a greater than 25% decrease in creatinine clearance while only 4 of the 14 patients (29%) treated with cisplatin alone had such a decrease in creatinine clearance (p < 0.004). The patients treated with the combination chemotherapy, however, received a higher dose of cisplatin (80.4 vs. 66.4 mg/m2, p < 0.02) and were treated longer (6.7 vs. 4.3 months, p < 0.002). Nevertheless, when the patients were matched for age, initial dose and cumulative dose of cisplatin, a higher frequency of nephrotoxicity persisted in patients treated with taxol and cisplatin as compared to cisplatin alone (72 as compared to 20%, p < 0.02). The patients in both groups were comparably hydrated; prerenal failure and urinary tract obstruction were excluded in all patients. Six months after completion of chemotherapy, a significantly lower creatinine clearance was still observed in patients treated with taxol and cisplatin combination therapy (46 vs. 76 ml/min, p < 0.01). In summary, a retrospective analysis of renal function in patients with gynecological cancers showed an increased nephrotoxicity in patients treated with taxol and

However, choose of treatment for operable breast cancer patients must be cautious due to high risk of lymphedema.

  14. Combination of chemotherapy, radiotherapy and surgery in the treatment of oral cancer

    International Nuclear Information System (INIS)

    In locally advanced oral cancer, the main modalities of treatment, e.g. surgery and radiotherapy, most often fail to control the disease when used singly. A combination policy of surgery and radiotherapy achieves adequate control of the disease. In order to improve the results in advanced oral cancer, chemotherapy given prior to and during radiation treatment and judicious combination of surgery offer the best possible approach in the management. The experience in the combination policy in the treatment of oral cancer in Northern India is dealt with. (auth.)

    1991-10-01

    From December 1986 to April 1990, 40 consecutive ovarian cancer patients who relapsed after response to cisplatin-based chemotherapy regimens were treated with seven courses of weekly cisplatin, in combination with epirubicin or etoposide. The overall response rate obtained with the intensive schedule was 60% and the complete response rate was 25%; median duration of response was 7 months and median survival time, 13.5 months. Responsive cases seem to have longer survival; a prognostic factor for response to salvage treatment and longer survival is the disease-free interval after the first-line chemotherapy. Weekly cisplatin as intensive treatment was very well tolerated and showed acceptable toxicity in both the combination protocols with epirubicin or etoposide. PMID:1959783

They received a cummulative dose ranging from 18 to 68 Gy (average dose : 50.5 Gy), in 2 Gy fractions. The response rate was 62 % (CR 1, PR 7). Two of the six patients with Stage III survived more than three years. Median survival time was 11.4 months for patients with Stage III and 4.7 months for Stage IV. Chemotherapy improved median survival duration for patients with advanced esophageal carcinoma but did not produce a significant improvement in survival, as reported in other recent series. (author)

  17. Chemotherapy by superselective intraarterial infusion of nedaplatin combined with radiotherapy for oral cancer

    International Nuclear Information System (INIS)

    Nedaplatin (CDGP), which is a CDDP derivative, has been reported to be an effective anticancer agent for head and neck cancer. This study was performed to assess the feasibility of chemotherapy by superselective intraarterial infusion of nedaplatin (CDGP) in patients with oral cancers. Ten patients were treated with chemotherapy by superselective intraarterial infusion of CDGP combined with radiotherapy. The complete and partial response rates were 7/10 (70%) and 3/10 (30%), respectively. Nine patients showed grade 1-2 hematological toxicity including leukocytopenia and anemia. Thrombocytopenia of grade 4 was seen in only one patient. However, all the patients were free from renal dysfunction. From these results, it is suggested that this combination therapy might be quite effective and safe. Further study will be needed to determine its efficacy against oral cancer. (author)

  20. Osteonecrosis of the femoral head in lymphoma patients treated with combined chemotherapy including corticosteroids

    International Nuclear Information System (INIS)

    Osteonecrosis of the femoral head developed in two patients with malignant lymphoma treated with combined chemotherapy. Pain was the main symptom. It was not possible to radiographically distinguish the necrotic lesions from metastatic tumour growth, and in both cases only histological examination revealed the true nature of bone destruction. The large doses of corticosteroids included in the treatment regiments were most likely of more importance in the etiology of the necrosis than the cytostatic drugs proper. (orig.)

    Full Text Available Vito Lorusso National Cancer Research Centre, Istituto Tumori Giovanni Paolo II, Bari, Italy Abstract: As recommended by most recent antiemetic guidelines, the optimal prophylaxis of chemotherapy-induced nausea and vomiting (CINV requires the combination of 5-HT3 receptor antagonist (RA with an NK1-RA. Moreover, the major predictors of acute and delayed CINV include: young age, female sex, platinum- or anthracycline-based chemotherapy, nondrinker status, emesis in the earlier cycles of chemotherapy, and previous history of motion/morning sickness. Despite improved knowledge of the pathophysiology of CINV and advances in the availability of active antiemetics, an inconsistent compliance with their use has been reported, thereby resulting in suboptimal control of CINV in several cases. In this scenario, a new antiemetic drug is now available, which seems to be able to guarantee better prophylaxis of CINV and improvement of adherence to guidelines. In fact, netupitant/palonosetron (NEPA is a ready-to-use single oral capsule, combining an NK1-RA (netupitant and a 5-HT3-RA (palonosetron, which is to be taken 1 hour before the administration of chemotherapy, ensuring the coverage from CINV for 5 days. We reviewed the role of NEPA in patients at high risk of CINV receiving highly emetogenic chemotherapy. In these patients, NEPA plus dexamethasone, as compared to standard treatments, achieved superior efficacy in all primary and secondary end points during the acute, delayed, and overall phases, including nausea assessment. Moreover, these results were also achieved in female patients receiving anthracycline plus cyclophosphamide-based chemotherapy. NEPA represents a real step forward in the prophylaxis of CINV.

  2. Role of combination chemotherapy in non-Hodgkin's lymphoma in children

    International Nuclear Information System (INIS)

    Eighteen children suffering from Non-Hodgkin's lymphoma were studied. Of these eighteen children, eight (44.4 percent) had well differentiated diffuse lymphocytic lymphoma and six (33.3 percent) had poorly differentiated diffuse lymphocytic lymphoma and four (22.3 percent) had histiocytic lymphoma. Histological study was based on the concept of Rappaport (1966). Children belonging to Stage IIB were treated with radiotherapy followed by combination chemotherapy and those with Stage IIIB and Stage IVB were treated with combination chemotherapy utilising cyclophosphamide, oncovin and prednisolone. The result of combination chemotherapy (COP) was dramatic and appears to have resulted in long term disease free survival. In well differentiated diffuse lymphocytic lymphoma in Stage IIB the life expectancy of two children was extended to 12 years with well maintained remission for 9.5 years. Recurrence rate was 44.4 percent. Death rate was 61.1 percent and median survival time was 26.7 months. In histiocytic lymphomas the results were unsatisfactory. Median survival time was 9.5 months.

  3. In vitro evaluation of photon and carbon ion radiotherapy in combination with chemotherapy in glioblastoma cells

    International Nuclear Information System (INIS)

    To evaluate the cytotoxic effect of carbon ion radiotherapy and chemotherapy in glioblastoma cells in vitro. The human glioblastoma (GBM) cell line U87 was irradiated with photon radiotherapy (RT) doses of 2 Gy, 4 Gy and 6 Gy. Likewise, irradiation with carbon ions was performed with single carbon doses of 0.125, 0.5, 2 and 3 Gy. Four chemotherapeutic substances, camptothecin, gemcitabine, paclitaxel and cisplatinum, were used for single and combination experiments. The assessment of the effect of single and double treatment on cell viability was performed using the clonogenic growth assay representing the radiobiological gold standard. The RBE of carbon ions ranges between 3.3 and 3.9 depending on survival level and dose. All chemotherapeutic substances showed a clear does-response relationhips. in their characteristic concentrations. For subsequent combination experiments, two dose levels leading to low and medium reduction of cell survival were chosen. Combination experiments showed additive effects independently of the drugs' mechanisms of action. Paclitaxel and campthothecin demonstrated the most prominent cytotoxic effect in combination with carbon ion radiotherapy. In conclusion, combination of carbon ion radiotherapy with chemotherapies of different mechanisms of action demonstrates additive effects. The most dominant effect was produced by paclitaxel, followed by camptothecin, as espected from previously published work. The present data serve as an important radiobiological basis for further combination experiments, as well as clinical studies on combination treatments

Our study discusses the combination of cytoreductive surgery with hyperthermic intrapleural chemotherapy to treat thymoma or thymic carcinoma with pleural dissemination.Methods: From February 2008 to January 2010, there were four patients with pleural thymoma metastases undergoing cytoreductive surgery and intrathoracic hyperthermic perfusion with chemotherapy at our department. After video-assisted thoracoscopic surgery, the hyperthermic perfusion system was set up for hyperthermic intrapleural chemotherapy. The thoracic cavity was perfused at a speed of approximately 1.8–2.3 L/min with 0.9% normal saline. The intrathoracic temperature remained between 42°C and 43°C. The perfusion process lasted for 2 hours.Results: There were no perioperative deaths. During the hyperthermic perfusion, the patient's core temperature varied from 36.3°C and 39.3°C and pulse varied from 59 beats/min and 126 beats/min. Intraoperative sinus tachycardia occurred in two elderly patients. No hematologic toxicity and nephrotoxicity was observed within 1 week after surgery. Postoperative pneumonia occurred in one elderly patient. Patients were followed up for 1–4 years. One elderly patient died of heart failure 1 year after surgery. There were no patients with local recurrence or metastases to distant sites.Conclusions: Cytoreductive surgery and intrathoracic hyperthermic perfusion with chemotherapy may be effective in treating thymoma or thymic carcinoma with pleural dissemination and has an encouraging impact on the patients’ long-term survival.Keywords: thymoma, pleural dissemination, surgery, hyperthermia

  8. Postoperative radiotherapy combined with intravesical chemotherapy for T2/T3 bladder cancer

    International Nuclear Information System (INIS)

    Objective: To compare the result of T2/T3 transitional cell carcinoma (TCC) of the urinary bladder after segmental cystectomy, treated by postoperative radiation plus intravesical chemotherapy and postoperative intravesical chemotherapy alone. Methods: From 1985 to Dec. 1995 patients with T2/T3 TCC bladder cancer who had been treated by segmental cystectomy were eligible for this retrospective analysis. Fifty-eight patients received postoperative radiotherapy plus intravesical chemotherapy (RT + IVC) and 35 patients were given postoperative intravesical chemotherapy (IVC) with thio-TEPA or Calmette-Gue' rin bacilli (BCG). For radiation, 8 or 18 MV X-ray was given with total dose of 50-60 Gy. Vesicoclysis was performed on 50-60 mg thio-TEPA twice per week and 0.5 mg BCG per week. Results: The 3-year local control rates of RT + IVC and IVC groups were 68.6% and 48.2% showing a difference statistically significant (x2 = 4.08, P = 0.044). The 3- and 5-year survival rates of RT + IVC and IVC groups were 70.7%, 49.5% and 59.9%, 35.7%, showing no significant difference (x2 = 1.77, P = 0.184). Among the 5 year survivors of the RT + IVC patients, 78.6% had their bladder preserved. Though untoward radiation reactions were severer, they were tolerated well. Conclusions: Combined radiation therapy plus intravesical chemotherapy is indicated for T2/T3 bladder cancer after segmental cystectomy. Multimodality therapy is more favored to improve both the local control and the possibility of preserving the bladder

    We examined treatment with or without anthracyclines in 72 eldery diffuse large B-cell lymphoma patients (age ≥ 65 years) in a retrospective cohort analysis. Factors leading to treatment without an anthracycline included age and ejection fraction, whereas markers of tolerability were similar between groups. This study highlights the details of anthracycline tolerability in elderly lymphoma patients. Introduction Although diffuse large B-cell lymphoma (DLBCL) can be cured with rituximab and anthracycline-based therapy, within the elderly population there are additional factors to consider in selecting a treatment regimen including comorbid conditions, decreased drug metabolism, decreased hematologic reserve, reduced performance status, and regimen-related toxicity. Patients and Methods We performed a retrospective cohort analysis of patients with DLBCL aged ≥ 65 years at time of diagnosis treated with either an anthracycline-containing regimen (ACR; n = 59) or a non-ACR (n = 13) to assess factors that led to treatment selection, tolerability, and outcomes. Results The mean age was 73 years in the ACR and 77 years in the non-ACR group (P = .009), and median left ventricular ejection fraction (LVEF) at diagnosis was 60% in the ACR group and 45% in the non-ACR group (P < .001). With an ACR, elderly DLBCL patients had a median overall survival of 28 months and a 2-year progression-free survival (PFS) of 64%. After an ACR, 14 patients [24%] (out of 59 total patients) had a decrease in LVEF, 7 patients [15%] (% is based off of those who we had the data collected, so this is out of 45 with this specific data) required a dose reduction of the anthracycline, and 15 patients [33%] (% is based off of those who we had the data collected, so this is out of 45 with this specific data) could not complete the regimen as planned. Hospitalization due to toxicity occurred in 20 patients [44%] (% is based off of those who we had the data collected, so this is out of 45 with data

    Full Text Available It has been found that preoperative plasma IGFBP-2 levels correlate with prognosis in glioma patients. The prognostic value of plasma IGFBP-2 after postoperative combined radiotherapy and chemotherapy in glioma patients is unknown. Plasma IGFBP-2 levels in 83 glioblastoma patients after postoperative radiotherapy plus chemotherapy were analyzed using an IGFBP-2 ELISA kit. We found that after standard therapy plasma IGFBP-2 levels significantly correlated with the patient's age (R = 0.738, P<0.001 and Karnofsky performance status (KPS, R =  -0.633, P<0.05. Cox proportional hazards models were used to calculate hazard ratios (HRs of death according to plasma IGFBP-2 levels adjusted for patient clinical characteristics. Plasma IGFBP-2 levels significantly correlated with overall survival in glioblastoma patients (multivariate HR = 1.035; 95% CI, 1.024-1.047; P<0.001. The effect of plasma IGFBP-2 levels on survival seemed to differ according to patients' age. Among patients older than 60, high plasma IGFBP-2 levels were associated with a significant increase in overall mortality (HR = 1.097; 95% CI, 1.055-1.140; P<0.001. In contrast, plasma IGFBP-2 levels conferred no significant effect on mortality among patients younger than 60. Elevated plasma IGFBP-2 levels after combined postoperative radiotherapy and chemotherapy in elderly glioblastoma patients correlate with poor KPS score and predicts poor prognosis.

    Objective: To assess the therapeutic effectiveness of preoperative neoadjuvant chemotherapy using a combination of paclitaxel and carboplatin on local advanced non-small cell lung cancer (NSCLC). Methods: Twenty-five patients with advanced NSCLC were treated with paclitaxel and carboplatin for 2 to 4 cycles before undergoing tumor resection and then postoperative chemotherapy/radiotherapy therapy for 2 to 4 cycles. Results: Following neoadjuvant chemotherapy, the most prominent side-effect was bone marrow restraint. The overall response rate of preoperative chemotherapy was 56%. The mean survival time was 26.5 months, with 1-, 2- and 5-year survival rates of 55%, 25%, and 16%, respectively. All NSCLC patients survived the perioperative period. Conclusion: Preoperative neoadjuvant chemotherapy combining paclitaxel and carboplatin produced minimal side-effect while increasing the probability that advanced NSCLC patients would be able to undergo surgery thus improving their prognosis.

    Full Text Available BACKGROUND: Metastatic melanoma has shown only limited responsiveness to chemotherapy or immunotherapy. The most commonly used single-agent chemotherapy comes from the nitrosourea group of agents and provides response rates of less than 20%. Several cytotoxic agents have been combined with no dramatic benefit. The incorporation of tamoxifen or interferon in chemotherapy regimens has proven effective in some trials. METHODS: From July 1998 to March 2002, 45 patients with metastatic melanoma were enrolled for the study. None of the patients had previously received chemotherapy. The aim of the study was to compare the activity of three combined regimens: CVD (cisplatin, vinblastine, dacarbazine chemotherapeutic combination, CVD with interferon (IFN alpha-2 - biochemotherapy, and CVD with tamoxifen. The study was conducted as a single center, controlled, prospective, randomized phase II study directed toward the disease. RESULTS: The best response rate (RR was observed in the CVD+IFN (6/15 group related to the CVD (4/15 and CVD+TAM (3/15 groups, without significant difference though. In 29 patients with 1 to 2 metastatic lesions, RR was 44.82% (CR-1, PR-12, SD-13, PD-3, while in 16 patients with 3 or more metastatic lesions RR was 0.0 % (CR-0, PR-0, SD-9, PD-7. The difference was statistically significant (p<0.005. The best responding metastatic sites were the lymph nodes (in 10 patients, but patients with lung, skin and liver lesions also responded. All patients experienced mild adverse effects. No treatment-related deaths occurred. The median survival was 12, 12, and 11 months in CVD+IFN, CVD and CVD+TAM group, respectively. Time to progression was about 8 months in all treated groups. CONCLUSION: Combined chemotherapy, biochemotherapy or chemohormonal therapy all showed some activity in metastatic melanoma. However, it is not yet possible to define standard therapy for this disease. Due to a limited number of patients evaluated so far in this

    We investigated the correlation of ataxia-telangiectasia-mutated (ATM) protein expression with clinicopathological features and prognosis in patients with breast cancer. ATM expression was determined by immunohistochemistry in 420 surgically resected breast tumors. ATM loss was observed in 126/407 evaluable cases (31.0 %), and was significantly associated with larger tumor size, lymph node metastasis, higher tumor grade, and ER- and/or PR-negative status. ATM loss was also associated with significantly lower disease-free survival rates than those in patients with intact ATM (5-year disease-free survival rate 81.2 vs. 90.7 %, p = 0.015). In multivariate analysis, ATM loss combined with abnormal p53 expression was an independent predictor of shorter disease-free survival [hazard ratio (HR) 3.48; 95 % confidence interval (CI), 1.48-8.17, p = 0.004]. A tendency towards a poorer prognosis was observed for tumoral ATM loss alone, although statistical significance was not reached (HR 1.74; 95 % CI 0.95-3.20; p = 0.075). In subgroup analysis, ATM loss was associated with shorter disease-free survival in patients who did not receive adjuvant anthracycline chemotherapy (5-year disease-free survival rate 92.7 % in intact ATM group vs. 68.1 % in ATM loss group, p = 0.002), but this poor prognosis was overcome in patients who did (5-year disease-free survival rate 89.8 vs. 84.4 %, p = 0.243), suggesting more benefit from anthracycline-based chemotherapy. Tumors with loss of ATM expression have a poor prognosis and their prognoses are dependent on the use of adjuvant anthracycline. ATM loss might be a practical tool for predicting benefits from anthracycline-based adjuvant therapy. PMID:27329169

  15. Combination of Intensive Chemotherapy and Anticancer Vaccines in the Treatment of Human Malignancies: The Hematological Experience

    2010-01-01

    Full Text Available In vitro studies have demonstrated that cancer-specific T cell cytotoxicity can be induced both ex vivo and in vivo, but this therapeutic strategy should probably be used as an integrated part of a cancer treatment regimen. Initial chemotherapy should be administered to reduce the cancer cell burden and disease-induced immune defects. This could be followed by autologous stem cell transplantation that is a safe procedure including both high-dose disease-directed chemotherapy and the possibility for ex vivo enrichment of the immunocompetent graft cells. The most intensive conventional chemotherapy and stem cell transplantation are used especially in the treatment of aggressive hematologic malignancies; both strategies induce T cell defects that may last for several months but cancer-specific T cell reactivity is maintained after both procedures. Enhancement of anticancer T cell cytotoxicity is possible but posttransplant vaccination therapy should probably be combined with optimalisation of immunoregulatory networks. Such combinatory regimens should be suitable for patients with aggressive hematological malignancies and probably also for other cancer patients.

    Superparamagnetic iron oxide (SPIO) nanoparticles have the potential for use as a multimodal cancer therapy agent due to their ability to carry anticancer drugs and generate localized heat when exposed to an alternating magnetic field, resulting in combined chemotherapy and hyperthermia. To explore this potential, we synthesized SPIOs with a phospholipid-polyethylene glycol (PEG) coating, and loaded Doxorubicin (DOX) with a 30.8% w/w loading capacity when the PEG length is optimized. We found that DOX-loaded SPIOs exhibited a sustained DOX release over 72 hours where the release kinetics could be altered by the PEG length. In contrast, the heating efficiency of the SPIOs showed minimal change with the PEG length. With a core size of 14 nm, the SPIOs could generate sufficient heat to raise the local temperature to 43 °C, sufficient to trigger apoptosis in cancer cells. Further, we found that DOX-loaded SPIOs resulted in cell death comparable to free DOX, and that the combined effect of DOX and SPIO-induced hyperthermia enhanced cancer cell death in vitro. This study demonstrates the potential of using phospholipid-PEG coated SPIOs for chemotherapy-hyperthermia combinatorial cancer treatment with increased efficacy.Superparamagnetic iron oxide (SPIO) nanoparticles have the potential for use as a multimodal cancer therapy agent due to their ability to carry anticancer drugs and generate localized heat when exposed to an alternating magnetic field, resulting in combined chemotherapy and hyperthermia. To explore this potential, we synthesized SPIOs with a phospholipid-polyethylene glycol (PEG) coating, and loaded Doxorubicin (DOX) with a 30.8% w/w loading capacity when the PEG length is optimized. We found that DOX-loaded SPIOs exhibited a sustained DOX release over 72 hours where the release kinetics could be altered by the PEG length. In contrast, the heating efficiency of the SPIOs showed minimal change with the PEG length. With a core size of 14 nm, the SPIOs could

    To improve the effectiveness of treatment for patients with stage C prostate cancer, therapy in combination with hormonal, radiation and chemotherapy was given for the initial period, and there after, hormonal therapy was continuously administered to 18 patients with chemotherapy and three patients without it. At the Social Health Insurance Medical Center, between May 1988 and August 1991, 21 patients were diagnosed to have stage C histologically confirmed adenocarcinoma of the prostate. The average age of the patients was 69.0 years. The tumor was well, moderate and poorly differentiated in 5, 6 and 10 patients, respectively. As hormonal therapy, orchiectomy was performed on 19 of the 21 patients. Furthermore, 11 patients were administered estramustine phosphate, 9 chlormadinone acetate, and one diethylstilbesterol diphosphate. As, radiation therapy, all patients were treated with AP-PA parallel opposing technique to small pelvis with a 12 cm x 12 cm treatment field (44-45 Gy) combined with conformation radiotherapy to prostate (20-26 Gy). Chemotherapy was performed using either one or a combination of the following; cis-diamminedichloroplatinum, adriamycin, cyclophosphamide, 5-fluorouracil, methotrexate and etoposide. The observation period was 54.5 months on the average. Recurrence was observed in 3 patients, for all of which the sites were at bone. The 5-year non-recurrence rate was 90.4% by Kaplan-Meier`s method. There were 4 deaths, three were due to prostate cancer and one to gastric cancer. The 5-year cumulative survival rate by Kaplan-Meier`s method was 90.5%. In conclusion, this treatment was effective for stage C cases of prostate cancer. (author)

    Hyperthermia in combination with chemotherapy has been widely used in cancer treatment. Our previous study has shown that rapid rate hyperthermia in combination with chemotherapy can synergistically kill cancer cells whereas a sub-additive effect was found when a slow rate hyperthermia was applied. In this study, we explored the basis of this difference. For this purpose, in vitro cell culture experiments with a uterine cancer cell line (MES-SA) and its multidrug resistant (MDR) variant MES-SA/Dx5 were conducted. P-glycoprotein (P-gp) expression, Caspase 3 activity, and heat shock protein 70 (HSP 70) expression following the two different modes of heating were measured. Doxorubicin (DOX) was used as the chemotherapy drug. Indocyanine green (ICG), which absorbs near infrared light at 808nm (ideal for tissue penetration), was chosen for achieving rapid rate hyperthermia. Slow rate hyperthermia was provided by a cell culture incubator. Two sets of thermal doses were delivered by either slow rate or rapid rate hyperthermia. HSP70 expression was highly elevated under low dose slow rate incubator hyperthermia while maintained at the baseline level under the other three treatments. Caspase3 level slightly increased after low dose slow rate incubator hyperthermia while necrotic cell death was found in the other three types of heat treatment. In conclusion, when given at the same thermal dose, slow rate hyperthermia is more likely to induce thermotolerance. Meanwhile, hyperthermia showed a dose dependent capability in reversing P-gp mediated MDR; when MDR is reversed, the combinational treatment induced extensive necrotic cell death. During this process, the rate of heating also played a very important role; necrosis was more dramatic in rapid rate hyperthermia than in slow rate hyperthermia even though they were given at the same dose.

    Combinational chemotherapy capable of targeted delivery and programmable multi-drug release leads to enhanced drug efficacy, and is highly desired for cancer treatment. However, effective approaches for achieving both features in a single treatment are limited. In the present work, we demonstrated programmed delivery of both chemotherapeutic and immunotherapeutic agents with tumor cell targeting capability by using SiO2 based self-decomposable nanoparticulate systems. The programmable drug delivery is realized by manipulating drug loading configurations instead of relying on external stimuli. Both in vitro and in vivo results showed specific drug binding to FAT1-expressing colon cancer cells. The loaded dual drugs were demonstrated to be delivered in a sequential manner with specific time intervals between their peak releases, which maximize the synergistic effect of the chemotherapeutics. These features led to significantly enhanced drug efficacy and reduced system toxicity. The tumor weight decreased by 1/350, together with a moderate increase in rats' body weight, which were observed when adopting the dual drug loaded nanoparticles, as compared to those of the control groups. The present system provides a simple and feasible method for the design of targeting and combination chemotherapy with programmed drug release.Combinational chemotherapy capable of targeted delivery and programmable multi-drug release leads to enhanced drug efficacy, and is highly desired for cancer treatment.

    Full Text Available Introduction: Lung cancer is the leading cause of cancer-associated death world-wide. And the lung cancer is generally divided into small cell lung carcinoma and non-small cell lung cancer. For advanced NSCLC, the chemotherapy and target therapy were the important treatment modality. This meta-analysis was to evaluate the clinical efficacy and toxicity between endostar combined chemotherapy and chemotherapy alone in Chinese patients. Materials and Methods: We searched the PubMed, EMBASE, and CNKI databases to find the potential relevant articles reporting the endostar combined with chemotherapy regimen in the treatment of nonsmall cell lung cancer in Chinese patients. The tumor response and toxicity difference between the two groups were demonstrated by odds ratio (OR and its 95% confidence interval (95% CI. All the data was pooled by Stata 11.0 (http://www.stata.com; Stata Corporation, College Station, TX software. Results: We included 14 studies published in Chinese or English studies. The pooled results showed adding endostar in the chemotherapy regimen can significant increase the objective response rate (OR = 2.42, 95% CI = 1.87-3.12, P = 0.00 and disease control rate (OR = 2.22, 95% CI = 1.68-2.94, P = 0.00. For toxicities, the pooled data showed no statistical difference for grade III-IV granulocytopenia risk (OR = 1.04, 95% CI = 0.74-1.44, P = 0.83. Nausea and vomiting (OR = 0.93 95% CI: 0.51-1.52, P = 0.78 and grade III-IV alopecia (OR = 0.99, 95% CI: 0.76-1.29, P = 0.95. The funnel plot showed no statistical publications. Conclusion: Combined treatment with endostar can improve the response rate for NSCLC patients without increasing the risk of developing severe adverse event.

    To assess the usefulness of radiofrequency (RF) thermal ablation with combined chemotherapy for the treatment of metastatic liver tumors, a non-randomized, comparative study was performed in 21 patients with metastatic liver tumors. Inclusion criteria were that these should be less than five in number and less than 6 cm in diameter. Two groups were designed for comparison of the local and remote (new intrahepatic or extrahepatic) tumor control rate (Group A : RF alone, n=11; Group B : RF + combined chemotherapy, n=10). There was no significant difference in age, sex, and mass size between the two groups (p > 0.05). All ablations were performed percutaneously with a 50W RF generator and 15G-needle electrode (RITA Medical System Inc.) under US guidance. In group B, six cycles of systemic chemotherapy were performed every month immediately after RF ablation. Follow-up CT scans were obtained within 24 hours of ablation and were compared with the findings of pre-ablation CT scanning. If an ablated lesion covered the mass without any residual enhancing foci, this was defined as complete ablation. Three and six months after ablation, local and remote tumor control rates were compared between the two groups (follow up : range 4-17 (mean, 10.2) months). In group A, the local tumor control rate was 43.8% (7/16) and 31.2% (5/16) at 3 and 6 months follow-up, respectively, while in group B, the corresponding rates were both 75% (15/20). At three months, the difference in this rate between the two groups was not significantly different (p>0.05), but at 6 months there was significant difference (p<0.05). At 6 months follow-up, the remote tumor control rate for Group A and Group B was 27.3% (3/11) and 80.0% (8/10), reflecting a significant difference between the two groups (p<0.05). In patients with metastatic liver tumor, radiofrequency thermal ablation with combined chemotherapy may be superior to RF thermal ablation alone for both local and remote tumor control.

    vs. {>=}6 cm in diameter, p = 0.008), and tumour response after induction chemotherapy and preoperative irradiation (clinically complete response + partial response vs. non-response, p = 0.0015). In the non conservative breast treatment group, of the 32 patients with no change in clinical tumour size after induction chemotherapy, the 10-year metastatic disease-free survival rate was 59% with only one local relapse. Arm lymphedema was noted in 17% (14 of 81) following axillary dissection and in 2.5% (1 of 39) without axillary dissection. Cosmetic results were satisfactory in 70% of patients treated by irradiation alone and in 51.5% of patients after wide excision and irradiation. Conclusion. - Despite the poor prognosis of patients with locally advanced non inflammatory breast cancer resistant to primary anthracycline-based regimen, aggressive locoregional management using preoperative irradiation and mastectomy with axillary dissection offers a possibility of long term survival with low local failure rate for patients without extensive nodal disease. On the other hand, the rate of local failure seems to be high in patients with clinical partial tumour response following induction chemotherapy and breast-conserving treatment combining preoperative irradiation and large wide excision.

    Full Text Available Objective  To investigate the influence of chemotherapy combined with autophagy inhibitor on apoptosis and calreticulin (CRT expression on colonic cancer cells. Methods  The colon cancer cells HCT116 were taken as the target in the present study. The inhibition rates (IC50 of chemotherapeutics oxaliplatin, 5-Fu and SN-38 were assessed by MTT assay. The changes in CRT expression on the membrane of HCT116 and apoptosis were determined with flow cytometry before and after treatment with chemotherapeutics. CRT location in HCT116 was detected by fluorescent immunoassay before and after treatment with chemotherapeutic agents. The influence on HCT116 autophagy was determined by Western blotting after treatment with these chemotherapeutic agents. The changes in CRT expression on HCT116 membrane and apoptosis were determined with flow cytometry before and after treatment with the chemotherapeutics combined with autophagy inhibitor chloroquine (CQ. Results  The ratio of apoptosis and membrane expression of CRT were elevated 12 hours after treatment with Oxaliplatin, 5-Fu and SN38, but without statistical significance. Fluorescent immunoassay showed a transposition of CRT from cytoplasm to the membrane after oxaliplatin treatment. Western blotting revealed that oxaliplatin, 5Fu and SN38 induced autophagy of HCT116 cells, and the autophagy was inhibited by the addition of CQ. Flow cytometric analysis indicated that the percentages of annexin V+ cells and membrane expression of CRT were higher after treatment with the chemotherapy agents combined with CQ. The upregulation of CRT expression on membrane was obviously higher after treatment with oxaliplatin combined with CQ than that before the treatment with these agents (P=0.027. Conclusion  Oxaliplatin combined with CQ may increase the apoptosis rate of HCT116 cells and upregulate CRT expression in the membrane. DOI: 10.11855/j.issn.0577-7402.2016.04.03

    OBJECTIVE Vertebral metastases are a common manifestation in patients with advanced cancer and treatment is often ineffective. This study was conducted to explore the efficacy of treating vertebral metastases by percutaneous vertebroplasty (PVP) combined with interventional chemotherapy.METHODS Seventy-five patients with vertebral metastases (42 men, 33women; ages 31~76 years) were divided into 2 groups: 39 cases were treated by PVP combined with chemotherapy (VPCC group), and 36 cases were treated by PVP alone (VP group). All procedures were guided by computed tomography (CT) scanning. The results and complications were evaluated by a questionnaire regarding pain and routine follow-up.RESULTS The response rate was significantly higher in the VPCC group than in the VP group (93.0% vs 74.4%, P<0.05); total response rates for the VPCC and VP groups were 25.6% and 10.3% respectively. A common complication related to VPCC was transient aggravating pain.CONCLUSION PVP may ameliorate pain, and consolidate the vertebrae of patients with vertebral metastases. Its short-term effect may be enhanced by adding drugs into the bone cement.

    Nanoparticle (NP)-based combination chemotherapy has been proposed as an effective strategy for achieving synergistic effects and targeted drug delivery for colon cancer therapy. Here, we fabricated a series of hyaluronic acid (HA)-functionalized camptothecin (CPT)/curcumin (CUR)-loaded polymeric NPs (HA-CPT/CUR-NPs) with various weight ratios of CPT to CUR (1 : 1, 2 : 1 and 4 : 1). The resultant spherical HA-CPT/CUR-NPs had a desirable particle size (around 289 nm), relative narrow size distribution, and slightly negative zeta potential. These NPs exhibited a simultaneous sustained release profile for both drugs throughout the time frame examined. Subsequent cellular uptake experiments demonstrated that the introduction of HA to the NP surface endowed NPs with colon cancer-targeting capability and markedly increased cellular uptake efficiency compared with chitosan-coated NPs. Importantly, the combined delivery of CPT and CUR in one HA-functionalized NP exerted strong synergistic effects. HA-CPT/CUR-NP (1 : 1) showed the highest antitumor activity among the three HA-CPT/CUR-NPs, resulting in an extremely low combination index. Collectively, our findings indicate that this HA-CPT/CUR-NP can be exploited as an efficient formulation for colon cancer-targeted combination chemotherapy.Nanoparticle (NP)-based combination chemotherapy has been proposed as an effective strategy for achieving synergistic effects and targeted drug delivery for colon cancer therapy.

  11. Results of radiotherapy and a combined radio- and chemotherapy for hypopharyngeal carcinomas

    International Nuclear Information System (INIS)

    We analyzed the results of radiotherapy in 36 patients with hypopharyngeal carcinoma. The overall 2-year and 5-year survival rates were 45.3% and 31.1%, respectively. For 23 patients given radical irradiation, the corresponding figures were 37.8% and 28.3%. However, in 16 patients receiving a combined therapy of radical irradiation and chemotherapy, mainly an intraarterial injection of cisplatin, the survivals were better; the 2-year survival rate was 50.0% and four patients have survived for more than three years without recurrence. In managing patients with hypopharyngeal carcinoma, this combined therapy would improve therapeutic outcome and also assist in larynx preservation. (J.P.N.)

    Eighty-three patients suffering from moderate or advanced malignant tumors were treated by combined chemotherapy and photodynamic therapy (PDT) in our hospital. The short term result of such management is very promising, the effectiveness seems to be nearly 100% and the general responsive rate is 79.5% (CR + PR). If compared with another group of 84 similar patients whom were treated with PDT alone, the short term efficacy is 85.7% while the general response rate is 54.7% (P statistic. The better result of the combined approach is probably due to the action of the chemotherapeutic agent, potentially blocking the mitosis of the cellular cycle at certain phases of the cancer cells, making the cell membrane become more permeable to the photochemical agent, HPD, and eliciting a better cancerocidal effect.

  13. Comparison of the effects of photon versus carbon ion irradiation when combined with chemotherapy in vitro

    International Nuclear Information System (INIS)

    Characterization of combination effects of chemotherapy drugs with carbon ions in comparison to photons in vitro. The human colon adenocarcinoma cell line WiDr was tested for combinations with camptothecin, cisplatin, gemcitabine and paclitaxel. In addition three other human tumour cell lines (A549: lung, LN-229: glioblastoma, PANC-1: pancreas) were tested for the combination with camptothecin. Cells were irradiated with photon doses of 2, 4, 6 and 8 Gy or carbon ion doses of 0.5, 1, 2 and 3 Gy. Cell survival was assessed using the clonogenic growth assay. Treatment dependent changes in cell cycle distribution (up to 12 hours post-treatment) were measured by FACS analysis after propidium-iodide staining. Apoptosis was monitored for up to 36 hours post-treatment by Nicoletti-assay (with qualitative verification using DAPI staining). All cell lines exhibited the well-known increase of killing efficacy per unit dose of carbon ion exposure, with relative biological efficiencies at 10% survival (RBE10) ranging from 2.3 to 3.7 for the different cell lines. In combination with chemotherapy additive toxicity was the prevailing effect. Only in combination with gemcitabine or cisplatin (WiDr) or camptothecin (all cell lines) the photon sensitivity was slightly enhanced, whereas purely independent toxicities were found with the carbon ion irradiation, in all cases. Radiation-induced cell cycle changes displayed the generally observed dose-dependent G2-arrest with little effect on S-phase fraction for all cell lines for photons and for carbon ions. Only paclitaxel showed a significant induction of apoptosis in WiDr cell line but independent of the used radiation quality. Combined effects of different chemotherapeutics with photons or with carbon ions do neither display qualitative nor substantial quantitative differences. Small radiosensitizing effects, when observed with photons are decreased with carbon ions. The data support the idea that a radiochemotherapy with common

    The dismal survival statistics for pancreatic cancer are due in large part to the notoriously poor response of these tumors to conventional therapies. Here we examine the ability of photodynamic therapy (PDT), using the photosensitizer verteporfin to enhance of the efficacy of traditional chemotherapy agents and/or eradicate populations that are nonresponsive to these agents. Using an in vitro 3D tumor model of pancreatic cancer combined with an imaging-based methodology for quantifying therapeutic response, we specifically examine PDT combination treatments with gemcitabine and oxaliplatin. We show that our 3D cell culture model recapitulates a more clinically-relevant dose response to gemcitabine, with minimal cytotoxic response even at high doses. The same cultures exhibit modest response to PDT treatments, but are also less responsive to this modality relative to our previous reports of monolayer dose response in the same cells. In combination we found no evidence of any enhancement in efficacy of either PDT or gemcitabine treatment regardless of dose or sequence (PDT before gemcitabine, or gemcitabine before PDT). However, when oxaliplatin chemotherapy was administered immediately after treatment with 2.5J/cm2 verteporfin PDT, there was an observable enhancement in response that appears to exceed the additive combination of either treatment alone and suggesting there may be a synergistic interaction. This observation is consistent with previous reports of enhanced efficacy in combinations of PDT with platinum-based chemotherapy. The contrast in results between the combinations examined here underscores the need for rational design of mechanism-based PDT combinations.

    Eight patients with untreated squamous cell carcinoma of the esophagus accompanying distant metastases who were treated by one to five cycles of chemotherapy consisting of Cisplatin and 120 hour infusion of 5-Fluorouracil were reported. Two patients showed complete response (CR), four partial response (PR), one minor response, and one no response. High response rate of 75% (6 of 8) was obtained. Radiation therapy was then administered to six of the patients. After definitive treatment, CR was obtained in four, and PR in two of the cases. However, relapses were noted in all four of the CR cases, with four at distant sites, and one locally. Five of the eight patients (62.5%) survived one year and two survived three years (25%). Two patients could not receive radiotherapy because of uncontrollable lung metastases or death from duodenal ulcer. Although the follow-up period is still short, the combined treatment of radiation and preradiation chemotherapy appears to be an effective treatment, and has made a major impact upon survival time in cases of disseminated esophageal carcinoma.

    Objective: There remains no standard first-line chemotherapeutic regimen for advanced gastric cancer (AGC). The aim of this study was to evaluate the efficacy and safety of combination regimen with weekly paclitaxel and S-1 as a firstline chemotherapy for AGC. Methods: Forty-six patients with AGC were included in this study. Paclitaxel was administered weekly at a dose of 60 mg/m2 on days 1, 8 and 15, S-1 was administered orally twice daily at 80 mg/m2/day for 2 weeks. The regimen was repeated every four weeks. Results: The results showed that the overall response rate was 45.7%, with 3 patients achieved complete response and 18 patients had a partial response, the disease control rate was 76.1%. The median progress free survival was 7.2 months [95% confidence interval (CI): 6.3–8.1 months] and the median overall survival was 11.6 months (95% CI: 10.6–12.6 months) after treatment with paclitaxel and S-1. Neutropenia occurred in 25 patients (54.3%) and grade 3/4 neutropenia was observed in 8 patients (17.4%), gastrointestinal reactions were the most common non-hematologic toxicities, while severe gastrointestinal toxicities were uncommon. Conclusion: The regimen of weekly paclitaxel and S-1 demonstrated activity and acceptable toxicity for AGC as a first-line chemotherapy.

    International Nuclear Information System (INIS)

    Clinical results of external beam radiotherapy combined with arterial infusion chemotherapy for advanced oral tongue cancer were analyzed. Forty patients with oral tongue squamous cell carcinoma underwent these combined therapy in the period between 1985 and 1996. Subject include 17 males and 23 females. Ages ranged from 27 to 84; median age was 64.2. The size of primary lesion was classified as follows: T1: 2 cases, T2: 16 cases, T3: 21 cases, T4: 1 case. Sixteen patients were treated as radical therapy, 24 as preoperative therapy. Anti-cancer drugs used for arterial infusion were 5-FU (31 patients) or CBDCA (9 patients). For 16 radical cases, ten (62.5%) were CR (tumor disappeared). In 4 cases (25.0%), tumor volume was decreased above 50%, but in 2 (12.5%) any local effect could not be confirmed. For 24 pre-operative cases, Complete Response (CR) was observed only in 12.5% (3 patients). Partial Response (PR) was observed in 15 patients (62.5%), no change (NC) in 6 (25.0%). In 6 from 15 PR cases disappearance of viable atypical cells could be confirmed from histological examinations of resected tongue. In results local control rate (CR rate) for 24 pre-operative cases was 37.5% (9/24). Severe complications, for examples ulcerations of the tongue or exposure of the mandible could not be found in any cases. CR was observed in 19 patients (47.5%) out of 40, and severe late complications were noted in no patients. External beam radiotherapy combined with arterial infusion chemotherapy was effective for locally advanced cancer of anterior two-thirds of the tongue. (author)

    Full Text Available Background: Colorectal carcinoma is one of most diagnosed solid malignant carcinoma. The chemotherapy combined with target drugs in the treatment of advanced colorectal cancer in not conclusive. Methods: The clinical studies reporting the activity and adverse events between chemotherapy alone versus chemotherapy combined with anti-epidermal growth factor receptor drugs were screened in the databases of Medline, the Cochrane Library, Wanfang and CNKI and included in this meta-analysis. The risk ratio (RR and its 95% confidence interval (CI for treatment response and adverse events were pooled by random or fixed effect model. Results: A total of 10 clinical studies reporting chemotherapy combined with the target in the treatment of advanced colorectal cancer were included in this study. The pooled RR was 3.26 (95% CI: 1.74-6.11, P 0.05, liver function damage (RR = 1.03, 95% CI: 0.74-1.42, myelosuppression (RR = 1.04, 95% CI: 0.83-1.31 and neurotoxicity (RR = 1.12, 95% CI: 0.93-1.35 were not different between the two groups. Conclusion: For Chinese patients with advanced colorectal cancer, chemotherapy combined with target drug can improve the response rate, but also increase the risk of nausea and vomiting.

  19. Intra-arterial and intra-venous chemotherapy combined with radiation in the treatment of brain tumours

    International Nuclear Information System (INIS)

    The present investigations were undertaken to study the effect of combining different modalities of chemotherapy with radiation in post-operative treatment of brain tumours. The conclusions and clinical implication of the investigations are as follows: The combination of combined intra-arterial chemotherapy followed by radiation leads to an increased median survival with more long term survivors in patients with anaplastic astrocytomas and in patients older than 40 years with astrocytomas. In patients with glioblastoma multiforme, this modality of treatment do not improve median survival, but an increased number of long-term survivors may be seen. Patients younger than 40 years with astrocytomas do not benefit from this modality of treatment. A parallelism exists between sensitivity to chemotherapy and response to radiotherapy. Patients who will benefit from the treatment may be selected early, normally two months after treatment start. Combining intra-arterial chemotherapy and radiation does not lead to an increased incidence of adverse CNS reactions. Specific transient abnormalities in the brain may occur during the first year after treatment and may be misinterpreted as tumour recurrence. EEG may be valuable in predicting adverse CNS reactions following treatment. Nuclear brain scan may be of valuable in selecting the patients who are in danger of developing adverse CNS reactions. Intra-arterial chemotherapy does have an effect in patients with brain tumours who have recurrent tumour after radiation. The most important prognostic factors are age, corticosteroid dependency at treatment start, performance status, histology and frontal lobe location. 103 refs., 2 tabs

  20. Sequential hemibody and local irradiation with combination chemotherapy for small cell lung carcinoma: a preliminary analysis

    International Nuclear Information System (INIS)

    Sequential hemibody irradiation (SHB) was integrated with combination chemotherapy and local irradiation (LRT) in the induction and consolidation phases of a therapeutic protocol for small cell lung carcinoma (SCLC). Forty-one previously untreated patients were entered into this program. Among 38 evaluable patients (20 with limited disease [LD] and 18 with extensive disease [ED]), the overall response rate was 63% (90% in LD and 33% in ED patients). The estimated overall survival is 8.1 months. The major toxicity has been myelosuppression - especially thrombocytopenia. The frequency of previously described acute radiation syndromes and radiation pneumonitis associated with hemibody irradiation have been substantially decreased at the current dosage with premedication and shielding techniques

    Full Text Available The nonsurgical strategies for locally advanced oral cancer are desirable. Superselective intra-arterial infusion with radiotherapy was utilized for this purpose, and there are two types of superselective intra-arterial infusion methods: The Seldinger method and the retrograde superselective intra-arterial chemotherapy (HFT method. In one case, the HFT method was applied to locally advanced tongue cancer, and the Seldinger method was used for additional administration of cisplatin (CDDP to compensate for a lack of drug flow in the HFT method. In another case, the HFT method was applied to locally advanced lower gingival cancer. The Seldinger method was applied to metastatic lymph nodes. In both cases, additional administration of CDDP using the Seldinger method resulted in a complete response. The combination of the HFT and Seldinger methods was useful to eradicate locally advanced oral cancer because each method compensated for the defects of the other.

    International Nuclear Information System (INIS)

    During 1977-81, thirteen patients of squamous cell carcinoma of the anal region have been treated by combined chemotherapy and radiotherapy at J.K. Cancer Institute, Kanpur. All these cases were biopsy proved and they did not receive radiotherapy or/and surgery prior to this treatment as either they refused for surgery or were found unfit either due to advance stage or low general condition or poor operation risk. All these cases responded to this treatment. Complete response was observed in 10 cases (76.8 per cent) and partial response in 3 cases (23.2 per cent). The overall duration of response varied from 11 to 62 months with a median of 46 months. (author)

    Cetuximab is a new medication that has recently been approved for the treatment of advanced colorectal cancer. To date we have had tittle experience in using this targeted agent. Eleven patients in our hospital with advanced colorectal cancer were treated with cetuximab and chemotherapy. Based on the curative effect of this combination therapy, we have concluded that the following nursing practices make an important contribution to the patients' prognosis and wellbeing: to establish a good nurse-patient relationship, to increase patient understanding of the side effects, to standardize the medications, to observe and to deal with the side effects of the medications(for example skin reaction, neutropenia, and diarrhea), and to provide continuous mental health care support and education.

    Objective: The purpose of this study was to assess the curative effect and adverse reaction of preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced non-small cell lung cancer (NSCLC). Methods: This prospective randomized controlled trial included 115 patients with locally advanced NSCLC were randomly divided into experimental and control groups and were treated from January 2007 to January 2010. The experimental group of 63 cases was treated with two cycles of induction chemotherapy before operation, radical surgery had been performed about three weeks after completion of chemotherapy, followed by received two cycles of chemotherapy. And the control group (52 cases) was treated at first with radical surgery, then treated with four cycles of chemotherapy. Two groups of the cases received routine thoracic radiotherapy with a total dose of 45 Gy. One cycle of gemcitabine combined with cisplatin regimen in-cluded gemcitabine 1000 mg/m2 on day 1 and day 8 and cisplatin 25 mg/m2 on day 1, day 2 and day 3 by intravenous infusion, with 21 days as one cycle. The tumor recurrence was evaluated by chest CT and abdominal B-ultrasound. Efficacy and toxicity results were compared by two groups. Results: All patients were followed up for three months to two years. The surgical stage of the experimental group reduced, two-years disease-free survival and postoperative recovery in the experimental group were better than in the control group, the difference was statistical significant. Toxicity and side effect after chemotherapy were mainly bone marrow suppression and gastrointestinal reactions, other complications included thrombocytopenia, leuko-penia, anemia, liver and kidney dysfunction were no significant difference in two groups. Conclusion: Preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced lung cancer can reduce the surgical staging and extend the postoperative disease-free survival.

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of transarterial infusion chemotherapy combined with high intensity focused ultrasound (HIFU) for the treatment of pancreatic carcinomas. Methods: A total of 64 patients with inoperable pancreatic carcinomas were randomly divided into study group (n=32) and control group (n=32). Transarterial infusion chemotherapy combined with HIFU was employed in patients of study group, while simple transarterial infusion chemotherapy was conducted in patients of control group. The effective rate, the clinical benefit rate (CBR), the occurrence of side effect and the survival time of the two groups were recorded. The results were compared between the two groups. Results: The effective rate (PR + MR), the median survival time and the one-year survival rate of the study group were 55.56%, 13.0 months and 68.75% respectively, while the effective rate (PR + MR), the median survival time and the one-year survival rate of the control group were 28.57%, 9.0 months and 43.75% respectively. Both the effective rate and the one-year survival rate of the study group were significantly higher than those of the control group (P<0.05). Conclusion: Compared with pure transarterial infusion chemotherapy, transarterial infusion chemotherapy combined with HIFU can significantly improve the short-term efficacy and increase the one-year survival rate for patients with advanced pancreatic carcinomas.

    Full Text Available Bevacizumab is the current standard of care treatment for recurring malignant glioma patients. However, most of the tumors become resistant to bevacizumab, and there is no standardized, effective chemotherapy for the malignant glioma patients after bevacizumab failure. Retrospective chart review was performed in order to identify the malignant glioma patients treated with oral, metronomic etoposide in combination with bevacizumab after being diagnosed with progressive disease while on bevacizumab. This review was approved by the Institutional Review Board (IRB of the University of California, Irvine. Six malignant gliomas patients met the inclusion criteria. The median progression-free survival (PFS for the anaplastic astrocytoma (AA patients was eight months, and the overall survival was 28 months. The two Glioblastoma Multiforme (GBM patients showed tumor progression after four to eight weeks of treatment with bevacizumab and etoposide, and died within four months of beginning the etoposide/bevacizumab regimen. In this limited study, patients with AA demonstrated prolonged control on combination treatment with bevacizumab and oral etoposide, despite initial tumor progression on bevacizumab. These results may warrant further investigation on a prospective clinical trial of this combination in AA patients who developed resistance to bevacizumab.

    PURPOSE: A number of prospective studies have shown that adjuvant CEF significantly improves disease-free and overall survival as compared to CMF in breast cancer patients. Our aim was to determine whether the benefit of epirubicin versus methotrexate differs according to TIMP-1 tumour cell...... immunohistochemistry (IHC). Tumours were regarded as TIMP-1 positive if epithelial breast cancer cells were stained using the anti-TIMP-1 monoclonal antibody VT7. RESULTS: By central assessment 75% of tumours were classified as tumour cell TIMP-1 positive. Among CEF-treated patients, individuals with TIMP-1 negative...... immunoreactivity seems to predict a favourable effect of epirubicin-containing adjuvant therapy in primary breast cancer. However, an independent study is awaited to validate the potential predictive value of TIMP-1 immunoreactivity...

    Despite more modern therapeutics approaches and the use of new drugs for chemotherapy, patients with ovarian cancer still have poor prognosis and therefore, new strategies for its cure are highly needed. One of the promising ways is combined therapy, which has many advantages as minimizing drug resistance, enhancing efficacy of treatment, and reducing toxicity. Combined therapy has rich and successful history in the field of ovarian cancer treatment. Currently use therapy is usually based on platinum-containing agent (carboplatin or cisplatin) and a member of taxanes (paclitaxel or docetaxel). In the mid-2000s this standard regimen has been expanded with bevacizumab, monoclonal antibody directed to Vascular Endothelial Growth Factor (VEGF). Another drug combination with promising perspectives is WP 631 given together with epothilone B (Epo B). WP 631 is a bisanthracycline composed of two molecules of daunorubicin linked with a p-xylenyl linker. Epo B is a 16-membered macrolide manifesting similar mechanism of action to taxanes. Their effectiveness against ovarian cancer as single agents is well established. However, the combination of WP 631 and Epo B appeared to act synergistically, meaning that it is much more potent than the single drugs. The mechanism lying under its efficacy includes disturbing essential cell cycle-regulating proteins leading to mitotic slippage and following apoptosis, as well as affecting EpCAM and HMGB1 expression. In this article, we summarized the current state of knowledge regarding combined therapy based on WP 631 and Epo B as a potential way of ovarian cancer treatment. PMID:26944437

    Background: Locoregional treatment of inflammatory breast cancer (IBC) is crucial because local relapses may be highly symptomatic and are commonly associated with distant metastasis. With a median follow-up of 20 years, we report here the long-term results of a monocentric clinical trial combining primary chemotherapy (CT) with a schedule of anthracycline-based CT and an alternating split-course of radiotherapy (RT Asterisk-Operator CT) without mastectomy. Methods and Materials: From September 1983 to December 1989, 124 women with nonmetastatic IBC (T4d M0) were treated with three cycles of primary AVCMF chemotherapy (anthracycline, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil) and then an alternating RT Asterisk-Operator CT schedule followed by three cycles of FAC. Hormonal therapy was systematically administered: ovarian irradiation (12 Gy in four fractions) or tamoxifen 20 mg daily. Results: Local control was achieved in 82% of patients. The 10- and 20-year local relapse rates were 26% and 33%, respectively, but only 10% of locally controlled cases were not associated with concurrent distant metastasis. The 10- and 20-year overall survival rates were 39% and 19%, respectively. Severe fibrosis occurred in 54% of patients, grade 3 brachial plexus neuropathy in 4%, grade 2 pneumonitis in 9%. Grade 1, 2 and 3 cardiac toxicity was observed in 3.8%, 3.8% and 1.2% of cases respectively. Conclusions: This combined regimen allowed good long-term local control without surgery. Survival rates were similar to those obtained with conventional regimens (primary chemotherapy, total mastectomy, and adjuvant radiotherapy). Since IBC continues to be an entity with a dismal prognosis, this approach, safely combining preoperative or postoperative radiation therapy and systemic treatments, should be reassessed when suitable targeted agents are available.

  16. A Phase III trial of neoadjuvant chemotherapy in patients with invasive bladder cancer treated with selective bladder preservation by combined radiation therapy and chemotherapy

    International Nuclear Information System (INIS)

    Purpose: To assess the long term efficacy of neoadjuvant MCV (Methotrexate, Cisplatin, Vinblastine) chemotherapy in patients with muscle invading bladder cancer treated by combined modality therapy with selection for consolidation by either cystectomy or Cisplatin and radiation (XRT) based on initial response. Patients and Methods: From 1990 through 1993, 126 patients (median age 68 years, range39 to 83 years) with clinical stage T2-T4aNXM0 bladder cancer were randomized following a thorough transurethral resection (TURBT), if possible, to receive (Arm 1, N=62) or not (Arm 2, N=64) 2 cycles of MCV prior to 39.6Gy pelvic irradiation with concurrent Cisplatin (100mg/M2) 2 courses, 3 weeks apart. Tumor response was scored as a clinical CR when the tumor-site biopsy and urine cytology were negative. The CR patients were treated with consolidation of an additional 25.2Gy to a total of 64.8Gy with 1 additional cycle of Cisplatin. Those with less than a CR were advised prompt cystectomy as were those with a subsequent invasive recurrence. The median follow up of surviving patients is 44 months. Results: 72% of patients completed the protocol with no or minor deviations; 62% on Arm 1 and 82% on Arm 2. The actuarial 5 year overall survival is 47%; 42% in Arm 1 and 50% in Arm 2. 40% of the patients had evidence of distant metastases at 5 years; 35% in Arm 1 and 43% in Arm 2. The 5 year survival with a functioning bladder is 36%, 32% in Arm 1, 39% in Arm 2. Among the 72 CR patients (60% CR in Arm 1 and 55% CR in Arm 2) 13% have had evidence of an invasive tumor relapse at 5 years. Six patients died during treatment; 5 in Arm 1, 1 in Arm 2. No patient required a cystectomy for treatment-related bladder morbidity. Conclusions: Two cycles of MCV neoadjuvant chemotherapy was not shown to provide an improved rate of CR to induction therapy or freedom from metastatic disease, or in five year overall survival. This absence of benefit in any of these endpoints may have resulted more

  17. Outcome of 289 locally advanced non-small cell lung cancer treated with radiotherapy alone and radiotherapy combined with chemotherapy

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze the outcome of locally advanced non-small cell lung cancer patients treated with radiotherapy and chemoradiotherapy. Methods: 289 patients who were treated either by radiotherapy alone (168 patients) or radiotherapy plus chemotherapy (121 patients) from Dec. 1999 to Dec. 2002 were entered into the database for analysis. Pathological types: squamous cancer (152), adenocarcinoma(74), squamoadenocarcinoma(2) and other types (2). 24 showed cancer unclassificable and 35 were diagnosed without pathological proof. Stages: 74 had III A and 215 III B stage disease. Among the 121 patients treated with combined modality, 24 were treated with concurrent chemoradiotherapy, 78 radiotherapy after chemotherapy(C + R), and 19 radiotherapy followed by chemotherapy(R + C). In patients treated by concurrent chemoradiotherapy or C + R, 38 received consolidation chemotherapy after induction treatment. Results: The 1-, 3-, 5-year overall survival, and the median survival were: 45% , 16% , 8%, and 16.2 months for all patients; 57%, 27%, 11%, and 21.7 months for stage IIIA; 41%, 12%, 7%, and 15.3 months for IIIB. By logrank test, clinical stage, KPS performance, tumor volume, hemoglobin level before treatment, consolidation chemotherapy, radiation dose, and response to treatment showed statistically dramatic impact on overall survival. The overall survival rate and median survival time were slightly higher in the combined group than in the radiotherapy alone group, but the difference is statistically insignificant. In Cox multivariable regression, stage and consolidation chemotherapy were independent prognostic factors; KPS performance, radiation dose, and response to treatment were at the margin of statistical significance. Esophagitis and pneumonitis of Grade II or higher were 24% and 8%, respectively. Failure sites included in the thorax(41%), outside of thorax(48%), and both in and outside the thorax(11%). There was no difference between the

    Hypercoagulable state and disorganized angiogenesis are two conspicuous characteristics during tumor progression. There are a considerable number of clinical trials focusing on the effects of anticoagulant and antiangiogenic drugs on the survival of cancer patients. Favorable outcomes have been observed. Excessive blood coagulation not only causes cancer-associated thrombosis, which is a common complication and is the second leading cause of death in patients, but also decreases intratumoral perfusion rates and drug delivery by reducing the effective cross-sectional area of blood vessels. Meanwhile, structural and functional abnormalities of the tumor microvasculature also compromise convective drug transport and create a hypoxic and acidic microenvironment. Vascular normalization strategy can temporarily recover the abnormal state of tumor vasculature by improving blood density, dilation, and leakiness, resulting in enhanced penetration of chemotherapies and oxygen within a short time window. In this article, we first review the evidence to support the opinion that anticoagulant and antiangiogenic therapy can improve cancer survival through several underlying mechanisms. Next, we speculate on the feasibility and value of the combined strategy and discuss whether such a combination has a synergistic antineoplastic effect in cancer patients by way of increasing blood vessel perfusion and drug distribution.

    Full Text Available Mesoporous silica nanoparticles (MSNs have been synthesized and loaded with both aluminum chloride phthalocyanine (AlClPc and cisplatin as combinatorial therapeutics for treating cancer. The structural and photophysical properties of the MSN materials were characterized by different spectroscopic and microscopic techniques. Intracellular uptake and cytotoxicity were evaluated in human cervical cancer (HeLa cells by confocal laser scanning microscopy (CLSM and 3-(4,5-dimethylthiazol-2-yl-5-(3-carboxymethoxyphenyl-2-(4-sulfophenyl-2H-tetrazolium (MTS assays, respectively. The CLSM experiments showed that the MSN materials can be readily internalized in HeLa cells. The cytotoxic experiments demonstrated that, after light exposure, the combination of both AlClPc and cisplatin compounds in the same MSN platform potentiate the toxic effect against HeLa cells in comparison to the control AlClPc-MSN and cisplatin-MSN materials. These results show the potential of using MSN platforms as nanocarriers for combination photodynamic and chemotherapies to treat cancer.

  1. Evaluation of multi-disciplinary treatment combined with intraarterial chemotherapy for carcinoma of the mesopharynx

    International Nuclear Information System (INIS)

    Forty-seven cases of carcinoma of the mesopharynx, treated from 1973 to 1981 at Gunma Cancer Center, were evaluated. The following results were obtained, 1) According to histopathologic diagnosis, 37 were well-differentiated squamous cell carcinoma and other cases were poorly differentiated squamous cell carcinoma. 2) Classification of the site of the disease showed the most frequent site was lateral wall type (31 cases, 65.9 per cent) followed by anterior wall (9 cases), superior wall (5 cases), and posterior wall types (2 cases). 3) According to TN classification, there were 1 case in T1, 14 cases in T2, 24 cases in T3, and 7 cases in T4, N distribution revealed 27 cases N0, 20 cases N1, N2 and N3. 4) The most common treatment was intraarterial chemotherapy using 5-FU combined with external irradiation (15 cases, 31.9 per cent), external irradiation alone (14 cases, 29.7 per cent), external irradiation with Radium (8 cases, 17.0 per cent), and combined with cryosurgery 5 cases, 10.6 per cent). The five-year cumulative survival rate was 35.3 per cent. The lesion of mesopharyngeal carcinoma takes verious forms, so the treatment policy cannot be a standard one. Thus multi-disciplinary treatment should be applied for this disease. (author)

    For the patients with breast cancer that are locally advanced or metastatic, treatment to control not only local disease but also distant metastasis is desirable. Hyperthermo-radio-chemotherapy (HRC) combined with surgery was performed for 16 patients with stage III or stage IV breast cancer and the clinical outcomes of this multimodal treatment were analyzed. The size of the primary tumor was significantly reduced after preoperative HRC with the CR rate of 18.8% (3/16) and PR rate of 81.3% (13/16). Three- and 5-year overall survival rates for the stage III patients were 100% and 87.5%, respectively; their 3- and 5- year disease free rates were 78.8% and 52.5%, respectively. One- and 3-year survival rates for the stage IV patients were 80.0% and 20.0%, respectively. No loco-regional recurrence was observed. HRC combined with surgery for advanced breast cancer patients was effective for down-staging of the primary tumor and maintaining local control. (author)

  4. Serum Biomarkers for the Detection of Cardiac Toxicity after Chemotherapy and Radiation Therapy in Breast Cancer Patients

    2014-10-01

    Full Text Available Multi-modality cancer treatments that include chemotherapy, radiation therapy, and targeted agents are highly effective therapies. Their use, especially in combination, is limited by the risk of significant cardiac toxicity. The current paradigm for minimizing cardiac morbidity, based on serial cardiac function monitoring, is suboptimal. An alternative approach based on biomarker testing, has emerged as a promising adjunct and a potential substitute to routine echocardiography. Biomarkers, most prominently cardiac troponins and natriuretic peptides, have been evaluated for their ability to describe the risk of potential cardiac dysfunction in clinically asymptomatic patients. Early rises in cardiac troponin concentrations have consistently predicted the risk and severity of significant cardiac events in patients treated with anthracycline-based chemotherapy. Biomarkers represent a novel, efficient, and robust clinical decision tool for the management of cancer therapy-induced cardiotoxicity. This article aims to review the clinical evidence that supports the use of established biomarkers such as cardiac troponins and natriuretic peptides, as well as emerging data on proposed biomarkers.

    The use of low doses of cytotoxic agents continuously for prolonged periods is an alternative for the treatment of patients with metastatic breast cancer who have developed resistance to conventional chemotherapy. The combination of metronomic chemotherapy with therapeutic vaccines might increase the efficacy of the treatment. Twenty one patients with metastatic breast cancer in progression and a Karnosky index ≥60%, were treated with metronomic chemotherapy (50 mg of cyclophospamide orally daily and 2.5 mg of methotrexate orally bi-daily), in combination with five bi-weekly subcutaneous injections of 1 mg of aluminum hydroxide-precipitated 1E10 anti-idiotype MAb (1E10-Alum), followed by reimmunizations every 28 days. Five patients achieved objective response, eight showed stable disease and eight had disease progression. Median time to progression was 9,8 months, while median overall survival time was 12,93 months. The median duration of the response (CR+PR+SD) was 18,43 months (12,20-24,10 months), being higher than 12 months in 76,9% of the patients. Overall toxicity was generally mild. Metronomic chemotherapy combined with 1E10-Alum vaccine immunotherapy might be a useful therapeutic option for the treatment of metastatic breast cancer due to its potential impact on survival and patient quality of live, low toxicity and advantages of the administration.

  6. Improved internal iliac artery chemotherapy combined with radiotherapy for the treatment of stage Ⅲ-Ⅳa cervical cancers

    International Nuclear Information System (INIS)

    Objective: To investigate the efficacy of modified internal iliac artery chemotherapy combined with radiotherapy for the treatment of stage Ⅲ-Ⅳa cervical cancers. Methods: A total of 70 patients with stage Ⅲ-Ⅳa cervical cancer, who were admitted to the authors' hospital (Department of Obstetric and Gynecology, Oncology) during the period from May 2005 to August 2009, were enrolled in this study. The clinical data were retrospectively analyzed. Modified internal iliac artery chemotherapy combined with radiotherapy was carried out in 32 patients (study group), and simple radiotherapy was adopted in 38 patients (control group). For patients in study group, puncturing of right femoral artery using Seldinger's technique was performed, which was followed by right uterine artery chemoembolization and subsequent super-selective left iliac artery chemotherapy, which lasted for three days. The chemotherapeutic drugs included cisplatin and fluorouracil. Distance external beam linear accelerator was used for radiotherapy together with 192 Ir high dose rate brachytherapy. For patients in control group, only distance external beam linear accelerator radiotherapy with 192 Ir high dose rate brachytherapy was employed, with the radioactive dose being a little bit smaller than that used in the study group. Results: The one-year survival rate for the study group and the control group was 78.1% and 55.3%, respectively (P0.05). The difference in the occurrence of radiotherapy-related complications was not significant between the two groups (P>0.05). Conclusion: For the treatment of stage Ⅲ-Ⅳa cervical cancers, modified internal iliac artery chemotherapy combined with radiotherapy is more effective than that of simple radiotherapy for a short-term period. The living quality of the patients can be markedly improved. Nevertheless, the five-year survival rate of chemotherapy combined with radiotherapy is not statistically difference from that of simple radiotherapy. (authors)

  7. Treatment of chronic lymphocytic leukemia by total body irradiation alone and combined with chemotherapy

    International Nuclear Information System (INIS)

    Total body irradiation (TBI) offers a new dimension in the treatment of chronic lymphocytic leukemia (CLL), a disease heretofore refractory to effective management. Excellent responses were observed in 50/57 (88%) consecutive patients with active CLL treated since 1964, and complete remissions were achieved in 22/57 (39%). Toxicity was acceptable and was minimized by combining TBI and chemotherapy in attenuated doses of each modality. The responders had a modified natural history of disease as evidenced by prolonged survival, improved quality of life, and even restoration of immunologic competence in some cases. Benefit was particularly evident for patients with a poor prognosis, i.e., those with anemia and/or thrombocytopenia prior to treatment. A median survival of 55 months for the 40 Stage III-IV patients is 2-3 times longer than described for comparable patients in other series. This experience indicates TBI may be the most effective single agent available for the treatment of CLL and warrants consideration in primary therapy

    The malignant progression of pancreatic ductal adenocarcinoma (PDAC) is accompanied by a profound desmoplasia, which forces proliferating tumor cells to metabolically adapt to this new microenvironment. We established the PDAC metabolic signature to highlight the main activated tumor metabolic pathways. Comparative transcriptomic analysis identified lipid-related metabolic pathways as being the most highly enriched in PDAC, compared with a normal pancreas. Our study revealed that lipoprotein metabolic processes, in particular cholesterol uptake, are drastically activated in the tumor. This process results in an increase in the amount of cholesterol and an overexpression of the low-density lipoprotein receptor (LDLR) in pancreatic tumor cells. These findings identify LDLR as a novel metabolic target to limit PDAC progression. Here, we demonstrate that shRNA silencing of LDLR, in pancreatic tumor cells, profoundly reduces uptake of cholesterol and alters its distribution, decreases tumor cell proliferation, and limits activation of ERK1/2 survival pathway. Moreover, blocking cholesterol uptake sensitizes cells to chemotherapeutic drugs and potentiates the effect of chemotherapy on PDAC regression. Clinically, high PDAC Ldlr expression is not restricted to a specific tumor stage but is correlated to a higher risk of disease recurrence. This study provides a precise overview of lipid metabolic pathways that are disturbed in PDAC. We also highlight the high dependence of pancreatic cancer cells upon cholesterol uptake, and identify LDLR as a promising metabolic target for combined therapy, to limit PDAC progression and disease patient relapse.

  9. Preoperative irradiation combined with chemotherapy impairs healing of bronchial anastomosis during the early postoperative period in rats

    International Nuclear Information System (INIS)

    The effect of preoperative irradiation and antineoplastic agents on healing at the site of bronchial anastomosis was investigated using rats. The bursting pressure in irradiation group and combined irradiation and chemotherapy group was significantly lower than in control and chemotherapy group at day 5 after operation. There was no significant difference in bursting pressure in all groups at day 7. The histologic finding of the anastomosis with hematoxyline and eosin (H and E) stain showed that submucosal connective tissue had not regenerated, and defects were seen in the submucosal tissue in irradiation and combined therapy group at day 3 and day 5. But, the connective tissue had matured in irradiation group at day 7 compared with control group. In conclusion, this study demonstrated that the healing of bronchial anastomosis was markedly delayed in early postoperative days in the rats receiving irradiation and combined therapy. (author)

  10. Lung cancer as a clinical model for combination chemotherapy and radiotherapy

    International Nuclear Information System (INIS)

    There are good theoretical reasons why the combination of chemotherapy [CT] and radiotherapy [RT] might be more effective for the treatment of cancer than either modality alone. This presentation will use clinical studies in lung cancer to illustrate the principles and benefits of combined CT/RT. Non-small cell lung cancer [NSCLC]. Since the NSCLC Collaborative Group meta-analysis (1) revealed that the addition of cisplatin based CT to RT confers a small but significant survival advantage in patients with locally advanced NSCLC, ongoing studies have been designed to determine the optimum timing, duration and type of CT. The meta-analysis data were largely derived from studies employing induction CT followed by RT, but two recent trials suggest that concomitant CT/RT may be superior (2,3). The concomitant approach has the theoretical advantages of platinum radiosensitisation, non-cross resistance of the two modalities and reduced overall treatment time. The available data suggest that cisplatin and carboplatin have similar efficacy. Induction CT before concomitant CT/RT is of uncertain value, and was less effective than concomitant CT/RT in one randomised phase II study (4). Small cell lung cancer [SCLC]. Two meta-analyses have demonstrated that in patients with limited disease, thoracic RT improves survival. RT appears to be more effective the earlier it is given. Recent studies have supported the use of b.d. fractionation and shorter treatment time (5,6). Platinum-based CT is not only superior to other CT but is preferred because of its compatibility with concurrent RT. Conclusion. In an interesting example of convergent evolution, recent developments in the treatment of both NSCLC and SCLC have resulted in broadly similar approaches for both histologies. In both diseases concomitant CT/RT instituted early may improve survival by increasing local control and reducing the probability of distant metastasis

  11. ‘Smart’ gold nanoshells for combined cancer chemotherapy and hyperthermia

    International Nuclear Information System (INIS)

    Nanomaterials that circulate in the body have great potential in the diagnosis and treatment of diseases. Here we report that ‘smart’ gold nanoshells can carry a drug payload, and that their intrinsic near-infrared (NIR) plasmon resonance enables the combination of chemotherapeutic and hyperthermia therapies. The ‘smart’ gold nanoshells (named DOX/A54@GNs) consist of (a) gold nanoshells (GNs) with NIR plasmon resonance, which not only act as nanoblocks but also produce local heat to allow hyperthermia; (b) an anticancer drug, doxorubicin (DOX), which was conjugated onto the nanoblocks by pH-dependent biodegradable copolymer thiol poly(ethylene glycol) derivatives via carbamate linkage; and (c) the targeting peptide A54 (AGKGTPSLETTP) to facilitate its orientation to liver cancer cells and enhance cellular uptake. The conjugated DOX was released from the DOX/A54@GNs much more rapidly in an acidic environment (pH 5.3) than in a neutral environment (pH 7.4), which is a desirable characteristic for intracellular tumor drug release. DOX-modified GNs showed pH-dependent release behavior, and the in vitro cell uptake experiment using ICP-AES and microscopy showed greater internalization of A54-modified GNs in the human liver cancer cell line BEL-7402 than of those without A54. Flow cytometry and fluoroscopy analysis were conducted to reveal the enhanced cell apoptosis caused by the A54-modified GNs under combined chemotherapeutic and hyperthermia therapies. These results imply that DOX/A54@GNs could be used as a multifunctional nanomaterial system with pH-triggered drug-releasing properties for tumor-targeted chemotherapy and hyperthermia. (paper)

  12. Experience with combination of docetaxel, cisplatin plus 5-fluorouracil chemotherapy, and intensity-modulated radiotherapy for locoregionally advanced nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Our aim was to evaluate the efficacy and toxicity of cisplatin, fluorouracil, and docetaxel chemotherapy plus intensity-modulated radiotherapy (IMRT) for locoregionally advanced nasopharyngeal carcinoma (NPC). Sixty patients with locoregionally advanced NPC were enrolled. Patients received IMRT plus three courses of neoadjuvant chemotherapy and two courses of adjuvant chemotherapy consisting of docetaxel (60 mg/m2/day on day 1), cisplatin (25 mg/m2/day on days 1-3), and 5-fluorouracil (500 mg/m2/day on days 1-3). The overall response rate to neoadjuvant chemotherapy was 89%. Three months after the completion of radiotherapy, 53 (93%) patients achieved complete regression, 3 (5%) achieved partial response (PR), and 1 experienced liver metastasis. However, among the 3 PR patients, 2 patients had no evidence of relapse in the follow-up. With a median follow-up of 27 months (range, 6-43), the 2-year estimated locoregional failure-free survival, distant failure-free survival, progression-free survival, and overall survival were 96.6, 93.3, 89.9, and 98.3%, respectively. Leukopenia was the main adverse effect in chemotherapy; 14 patients experienced grade 3 or grade 4 neutropenia, and 1 patient developed febrile neutropenia. The nonhematological adverse events included alopecia, nausea, vomiting, anorexia, and diarrhea. The incidence of grade 3 acute radiotherapy-related mucositis was 28.3%; no grade 4 acute mucositis was observed. No grade 3 or grade 4 hematological toxicity occurred during radiotherapy. None of the patients had interrupted radiotherapy. The common late adverse effects included xerostomia and hearing impairment. Neoadjuvant-adjuvant chemotherapy using cisplatin, fluorouracil, plus docetaxel combined with IMRT was an effective and well-tolerated alternative for advanced NPC. (author)

  14. The treatment of advanced stage favorable histology non-Hodgkin's lymphoma: a preliminary report of a randomized trial comparing single agent chemotherapy, combination chemotherapy, and whole body irradiation

    International Nuclear Information System (INIS)

    Between 1975 and 1978, 51 patients with favorable histology non-Hodgkin's lymphomas, pathologic stage III-IV, were treated prospectively on a randomized treatment protocol. Treatment options were single alkylating agent chemotherapy, combination chemotherapy with cyclophosphamide, vincristine, and prednisone (CVP), or fractionated whole body irradiation followed by low dose involved field irradiation. The median follow-up interval in this group of patients is not 41 mo. Actuarial survival is excellent, 84% at 4 yr for the entire group, with similar survival observed for each of the three treatment options. Initial complete remission rates (64%, 88%, and 71%) were not significantly different in the three treatment arms. Frequent relapse after initial remission induction was noted, however, with a freedom from relapse at 4 yr of only 25%. The toxicities of the three therapies were acceptable. Acute complications of therapy were most numerous in the group of patients treated with CVP; however, long-term hematologic depression was most commonly observed in patients treated with whole body irradiation. In general, hematologic complications were more frequent among patients who had marrow involvement and intact spleens at the time of initial therapy. The relationship of this study to other clinical trials in the management of patients with advanced stage favorable histology lymphomas and its implications for future clinical trials are discussed

    The purpose of this study was to create a prognostic model for distant metastasis in patients with locally advanced NPC who accept concurrent chemotherapy combined with intensity-modulated radiotherapy (CCRT) to identify high-risk patients who may benefit from neoadjuvant chemotherapy (NACT). A total of 881 patients with newly-diagnosed, non-disseminated, biopsy-proven locoregionally advanced NPC were retrospectively reviewed; 411 (46.7%) accepted CCRT and 470 (53.3%) accepted NACT followed by CCRT. Multivariate analysis demonstrated N2–3 disease, plasma Epstein–Barr virus (EBV) DNA > 4000 copies/mL, serum albumin ≤46 g/L and platelet count >300 k/cc were independent prognostic factors for distant metastasis in the CCRT group. Using these four factors, a prognostic model was developed, as follows: 1) low-risk group: 0–1 risk factors; and 2) high-risk group: 2–4 risk factors. In the high-risk group, patients who accepted NACT + CCRT had significantly higher distant metastasis-free survival and progression-free survival rates than the CCRT group (P = 0.001; P = 0.011). This simple prognostic model for distant metastasis in locoregionally advanced NPC may facilitate with the selection of high-risk patients who may benefit from NACT prior to CCRT. PMID:26564805

    AIM: To evaluate the efficacy of combination chemotherapy with interferon-α (IFNα) and 5-fluorouracil (5-FU) in patients with advanced hepatocellular carcinoma (HCC).METHODS: Twenty-eight HCC patients in advanced stage were enrolled in the study. They were treated with IFNα/5-FU combination chemotherapy. One cycle of therapy lasted for 4 wk. IFNα (3× 106 units) was subcutaneously injected thrice weekly on days 1, 3, and 5 for 3 wk, and 5-FU (500 mg/d) was administered via the proper hepatic artery for 5 consecutive days per week for 3 wk. No drugs were administered during the 4th wk. The effect of combination chemotherapy was evaluated in each patient after every cycle based on the reduction of tumor volume.RESULTS: After the 1st cycle of therapy, 16 patients showed a partial response (PR, 57.1%) but none showed a complete response (CR, 0%). At the end of therapy,the number of patients who showed a CR, PR, or no response (NR) was 1, 10, and 17, respectively. The response rate for therapy (CR+PR) was 21.5%. Biochemical tests before therapy were compared between responsive (CR+PR) and non-responsive (NR) patients, but no significant differences were found for any of the parameters examined, indicating that no reasonable predictors could be identified in our analysis.CONCLUSION: Attempts should be made to discriminate between responders and non-responders by evaluating tumor size after the first cycle of IFNα/5-FU combination chemotherapy. For non-responders, therapy should not proceed to the next cycle, and instead, different combination of anticancer drugs should be explored.

  17. Influence of interventional chemotherapy combined with traditional Chinese medicine on the immune function of elderly patients with advanced lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the influence of interventional chemotherapy combined with traditional Chinese medicine on the immune function in elderly patients with advanced lung cancer and to establish a comprehensive therapeutic pattern which is effective and economical with lower side-effects. Methods: A total of 60 aged patients with lung cancer were randomly and equally divided into two groups with 30 patients in each group. Patients in group A were purely treated with traditional Chinese medicine and patients in group B were treated with a combination of interventional chemotherapy and traditional Chinese medicine. And two therapeutic courses (6-8 weeks) were conducted in both groups. The serum T-lymphocyte subsets levels of CD3, CD4, CD8, CD4/CD8, NK cells and CD4+CD25+ Treg cell levels were estimated with flow cytometry. The results were statistically analyzed. Results: No significant difference in serum levels of T cell subsets and CD4+CD25+ Treg cell levels existed between the two groups, both before and after the treatment (P > 0.05). However, after the treatment the CD4+CD25+ Treg cell level in group B was significantly lower than that in group A (P < 0.05). The short-term effective rate and the total clinical benefit rate in group B were 40% and 73.3% respectively, which were much better than those in group A (20% and 63.3% respectively). Conclusion: Interventional chemotherapy combined with traditional Chinese medicine will not damage the immune function of elderly patients with advanced lung cancer, on the contrary, the combination therapy, through effectively reducing the suppressor T cell level,shows excellent short-term effect. It indicates that interventional chemotherapy combined with Chinese medicine is an effective comprehensive therapeutic mode for elderly patients with advanced lung cancer. (authors)

  18. Potent antitumor activities of recombinant human PDCD5 protein in combination with chemotherapy drugs in K562 cells

    International Nuclear Information System (INIS)

    Conventional chemotherapy is still frequently used. Programmed cell death 5 (PDCD5) enhances apoptosis of various tumor cells triggered by certain stimuli and is lowly expressed in leukemic cells from chronic myelogenous leukemia patients. Here, we describe for the first time that recombinant human PDCD5 protein (rhPDCD5) in combination with chemotherapy drugs has potent antitumor effects on chronic myelogenous leukemia K562 cells in vitro and in vivo. The antitumor efficacy of rhPDCD5 protein with chemotherapy drugs, idarubicin (IDR) or cytarabine (Ara-C), was examined in K562 cells in vitro and K562 xenograft tumor models in vivo. rhPDCD5 protein markedly increased the apoptosis rates and decreased the colony-forming capability of K562 cells after the combined treatment with IDR or Ara-C. rhPDCD5 protein by intraperitoneal administration dramatically improved the antitumor effects of IDR treatment in the K562 xenograft model. The tumor sizes and cell proliferation were significantly decreased; and TUNEL positive cells were significantly increased in the combined group with rhPDCD5 protein and IDR treatment compared with single IDR treatment groups. rhPDCD5 protein, in combination with IDR, has potent antitumor effects on chronic myelogenous leukemia K562 cells and may be a novel and promising agent for the treatment of chronic myelogenous leukemia.

    Although many treatment modalities and schedules for non-muscle-invasive bladder cancer (NMIBC) exist, all yet prove to have limitations. Therefore the search for new forms of therapy continues. One of these forms consists of combining intravesical chemotherapy, typically mitomycin C (MMC), with hyperthermia achieved by a microwave-applicator. We aimed to review the current status of intravesical radiofrequency (RF) induced chemohyperthermia (CHT) for NMIBC with regard to efficacy, adverse-events (AEs) and its future perspective. A search for RF-induced CHT in MEDLINE, Embase, Cochrane and ClinicalTrials.gov databases was performed. Relevant conference abstracts were searched for manually. If applicable, experts on the area were consulted. Papers were selected based on abstract and title. A table of newly published clinical trials since 2011 was constructed. No meta-analysis could be performed based on these new papers. Efficacy proved to be better for RF-induced CHT compared to both MMC alone and bacillus Calmette-Guérin (BCG) instillations, with the latter being based on just one abstract of a randomised controlled trial. The AE rate in CHT is higher compared to MMC instillation, but is similar compared to BCG, albeit different in the type of AE. In almost all studies no severe AEs are reported. Although heterogeneity in methodology exists, RF-induced CHT seems promising. However, alternative methods of applying hyperthermia are starting to present their first results, imposing as effective options too. Intravesical RF-induced CHT may become an alternative for BCG instillation, and possibly for cystectomy, although further level 1 evidence is required for both reliable and reproducible data on efficacy and adverse events.

    Background. Traditionally, radiation therapy plans are optimized without consideration of chemotherapy. Here, we model the risk of radiation pneumonitis (RP) in the presence of a possible interaction between chemotherapy and radiation dose distribution. Material and methods. Three alternative treatment plans are compared in 18 non-small cell lung cancer patients previously treated with helical tomotherapy; the tomotherapy plan, an intensity modulated proton therapy plan (IMPT) and a three dimensional conformal radiotherapy (3D-CRT) plan. All plans are optimized without consideration of the chemotherapy effect. The effect of chemotherapy is modeled as an independent cell killing process using a uniform chemotherapy equivalent radiation dose (CERD) added to the entire organ at risk. We estimate the risk of grade 3 or higher RP (G3RP) using the critical volume model. Results. The mean risk of clinical G3RP at zero CERD is 5% for tomotherapy (range: 1-18 %) and 14% for 3D-CRT (range 2-49%). When the CERD exceeds 9 Gy, however, the risk of RP with the tomotherapy plans become higher than the 3D-CRT plans. The IMPT plans are less toxic both at zero CERD (mean 2%, range 1-5%) and at CERD = 10 Gy (mean 7%, range 1-28%). Tomotherapy yields a lower risk of RP than 3D-CRT for 17/18 patients at zero CERD, but only for 7/18 patients at CERD = 10 Gy. IMPT gives the lowest risk of all plans for 17/18 patients at zero CERD and for all patients with CERD = 10 Gy. Conclusions. The low dose bath from highly conformal photon techniques may become relevant for lung toxicity when radiation is combined with cytotoxic chemotherapy as shown here. Proton therapy allows highly conformal delivery while minimizing the low dose bath potentially interacting with chemotherapy. Thus, intensive drug-radiation combinations could be an interesting indication for selecting patients for proton therapy. It is likely that the IMRT plans would perform better if the CERD was accounted for during

    Treatment results were retrospectively analyzed in 61 cases of non-Hodgkin's lymphoma (stage I: 21 cases, stage II: 40 cases) that were diagnosed between July, 1977 and Oct., 1987. The actuarial five-year survival rates for stage I and II were 84.4% and 50.7% respectively, whereas those were 47.5% and 75.3% respectively for those treated by radiotherapy (XRT) alone and combined radio-chemotherapy including all cases of stage I and II. Also the results of combined radio-chemotherapy were significantly better than those of XRT alone. Particularly, the pre-radio-chemotherapy group had a 5-year survival rate of 85.7%. In conclusion, the results of combined radio-chemotherapy, particularly pre-radio-chemotherapy, was significant between those of XRT alone. (author)

  6. Patterns of failure in combined chemotherapy and radiotherapy for limited small cell lung cancer: Southeastern Cancer Study Group experience

    International Nuclear Information System (INIS)

    In this analysis, we compare the patterns of failure in the first 12 months for 660 eligible patients randomized to two Southeastern Cancer Study Group (SECSG) protocols for limited extent, small cell carcinoma of the lung between 1978 and 1985. In each protocol, a different schedule of radiotherapy was given in conjunction with combination chemotherapy and was compared with combination chemotherapy alone. In protocol 78 LUN 328, radiotherapy was given between courses of chemotherapy, and in protocol LUN 81343, it was given simultaneously. The rates of local failure, either as an initial or subsequent site, in the first 12 months were significantly lower when thoracic irradiation was given than when it was not (P less than .01). When the 2 radiotherapy arms were compared, there were no significant differences in the rates of local failure alone, but a smaller proportion of patients developed both local failure and distant metastases (P less than .01) when simultaneous radiotherapy was administered. Survival on all 4 arms was similar during the first 2 years of patient study. After 2 years, both radiotherapy regimens showed a trend toward improved survival compared with the combination drug alone (cyclophosphamide, doxorubicin, vincristine) arms. On both protocols, survival from 12 months was significantly longer for those with local control at 12 months than for those who did not show local control

    We report the successful treatment of multiple lung metastases after hepatic resection for hepatocellular carcinoma (HCC) with combined docetaxel, cisplatin (CDDP), and enteric-coated tegafur/uracil (UFT-E). A 68-year-old man was diagnosed with multiple lung metastases of HCC 7 mo after partial hepatectomy for HCC. Oral UFT-E was given daily and docetaxel and CDDP were given intra-arterially (administered just before the bronchial arteries) every 2 wk via a subcutaneous injection port. One month after starting chemotherapy, levels of tumor marker, protein induced by vitamin K absence Ⅱ (PIVKA-Ⅱ), decreased rapidly, and after a further month, chest X-ray and computed tomography revealed the complete disappearance of multiple liver metastases. Two years after the combined chemotherapy, HCC recurred in the liver and was treated but no pulmonary recurrence occurred. In the absence of a standardized highly effective therapy, this combined chemotherapy with docetaxel, CDDP and UFT-E may be an attractive option for multiple lung metastases of HCC.

    Full Text Available Background and objective In recent years, there has been a large number of studies and reports about the efficacy and safety of recombinant human endostatin (rh-endostatin, an anti-angiogenic drug, in treatment of advanced lung cancer. Authentic assessment of rh-endostatin treatment in lung cancer is important. The aim of this study is to assess the clinical efficacy and safety of rh-endostatin combined with chemotherapy in the treatment of patients with non-small cell lung cancer (NSCLC. Methods Cochrane systematic review methods were used in the data selection, and data were selected from the Cochrane Library, EMBASE, Medline, SCI, CBM, CNKI, and etc electronic database to get all clinical controlled trials. The retrieval time was March 2010. The objects of these randomized controlled trials were advanced NSCLC patients and in the experimental group was rh-endostatin combination chemotherapy, in the control group was chemotherapy alone to compare the efficacy of two groups. The quality of included trials were evaluated by two reviewers independently. The software RevMan 5.0 was used for meta-analyses. Results Fifteen trials with 1,326 patients were included according to the including criterion. All trials were randomized controlled trials, and two trials were adequate in reporting randomization. Thirteen trials didn’t mention the blinding methods. Meta analysis indicated that the NPE arm (Vinorelbine+cisplatin+rh-endostatin had a different response rate compared with NP (Vinorelbine+cisplatin arm (OR=2.16, 95%CI: 1.57-2.99. The incidences of severe leukopenia (OR=0.94, 95%CI: 0.66-1.32 and severe thrombocytopenia (OR=1.00, 95%CI: 0.64-1.57 and nausea and vomiting (OR=0.85, 95%CI: 0.61-1.20 were similar in the NPE arm compared with those in the NP arm. The NPE plus radiotherapy (RT arm had a similar response rate compared with NP plus RT arm (OR=2.39, 95%CI: 0.99-5.79. The incidences of leukopenia (OR=0.83, 95%CI: 0.35-1.94 and

  9. Enhanced antitumor effect and mechanism of chemotherapy combined with low dose radiation

    International Nuclear Information System (INIS)

    It is well known that whole body irradiation (WBI) with low dose X-rays could improve the function of the immunological system and the antitumor efficacy of local large dose irradiation. In order to study the adjuvant effect of WBI with low dose on the tumor suppressive effect of chemotherapy, 6 hours before mitomycin C or cyclophosphamide I.P. administration, WBI with 75 mGy was given to C57BL/6 mice bearing Lewis Lung carcinoma. It was found that WBI with 75 mGy X-rays could markedly enhanced the suppressive effect of chemotherapy on tumor and significantly increase some immunological parameters related to tumor killing. The results suggested that WBI with 75 mGy X-rays could reduce the immunological damage of tumor-bearing mice caused by chemotherapy and enhance the antitumor efficacy of cytotoxic agents

    Despite troubled beginnings, anticancer chemotherapy has made significant contribution to the control of cancer in man, particularly within the last two decades. Early conceptual observations awakened the scientific community to the potentials of cancer chemotherapy. There are now more than 50 agents that are active in causing regression of clinical cancer. Chemotherapy's major conceptual contributions are two-fold. First, there is now proof that patients with overt metastatic disease can be cured, and second, to provide a strategy for control of occult metastases. In man, chemotherapy has resulted in normal life expectancy for some patients who have several types of metastatic cancers, including choriocarcinoma, Burkitt's lymphomas, Wilm's tumor, acute lymphocytic leukemia, Hodgkins disease, diffuse histiocytic lymphoma and others. Anticancer chemotherapy in Veterinary medicine has evolved from the use of single agents, which produce only limited remissions, to the concept of combination chemotherapy. Three basic principles underline the design of combination chemotherapy protocols; the fraction of tumor cell killed by one drug is independent of the fraction killed by another drug; drugs with different mechanisms of action should be chosen so that the antitumor effects will be additive; and since different classes of drugs have different toxicities the toxic effects will not be additive.

    Full Text Available Background: Bevacizumab and irinotecan may represent one of the most active treatments in progressive malignant glioma. Limited published experience with bevacizumab in patients with CNS tumors raises concerns regarding toxicity, particularly in regards to hemorrhage and thromboembolism.Methods: We retrospectively reviewed 36 patients with progressive malignant glioma after prior resection, chemotherapy and radiation who were treated with bevacizumab at our institution. Patients were evaluated for bevacizumab-related adverse events, time to treatment failure (TTF and overall survival (OS. Two patients who progressed or died prior to completion of 4 cycles of therapy were analyzed for adverse events only.Results: Patients were treated with bevacizumab alone (1, bevacizumab plus irinotecan (31, or bevacizumab plus carboplatin (4. In 34 patients who received >4 cycles of bevacizumab, median TTF and OS were 16 and 32 weeks, respectively. Toxicities included 1 arterial thrombosis, 4 venous thromboses, and 3 clinically significant CNS hemorrhages.Conclusion: Overall, our results confirm the efficacy and safety of bevacizumab in combination with chemotherapy in patients with progressive malignant glioma. Although the TTF and OS were less than previously reported with the combination of bevacizumab and irinotecan, this was an unselected patient population with 50% of patients having received >1 prior chemotherapy regimen.

  13. 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)

    To preliminarily determine the appropriate dosage of carboplatin (CBP) at AUC of 5 mg·Ml-1·min-1 in the combination chemotherapy for Chinese senile patients with non-small cell lung cancer (NSCLC). Thirty-five Chinese senile patients with NSCLC in advanced stage (Ⅲ/Ⅳ) were given 96 cycles of combination chemotherapy. Chemotherapy schedules included Taxol+CBE Gemzar+CBP and NVB+CBP. The dose of CBP was at 5 mg·mL-1·min-1 of area under the concen- tration-time curve (AUC). Side effects and quality of life were observed before and after the chemo- therapy. Myelosuppression was severe and commonly observed. Grade 3/4 of granuiocytopenia was found in 47.9% (46/96) of the patients and grade 3/4 of thrombocytopenia was noted in 28.1% (27/96) of the subjects. However, other side effects were slight. The mean score of quality of life (QOL), ac- cording to the criteria of QOL for Chinese cancer patients had reduced 6.8. At 5 mg·mL-1·min-1 by AUC, the hematological toxicity of CBP was severe and it had some negative effects on the QOL. The administration of CBP at 5 mg·mL-1·min-1 by AUC may be too high for Chinese senile patients with non-small cell lung cancer.

  16. Multimodal treatment utilizing intraoperative radiotherapy and high-dose combination chemotherapy with autologous bone marrow transplantation for advanced pancreatic cancer

    International Nuclear Information System (INIS)

    Of 51 cases of pancreatic cancer, intraoperative radiotherapy was given in 9, and pain-relief was noted in 6. Excluding 2 patients who died from hemorrhage from the gastrointestinal tract soon after irradiation, the mean survival period was 2.9 mo. in cases with distant metastatic cases and 7.8 mo. in cases without it. Hemorrhage, necrosis and stenosis of the gastrointestinal tract were observed as complications. ABMT and high-dose chemotherapy were given in combination in 7 cases, of which the mean survival period was 3.9 mo. in cases with distant metastasis and 7.0 mo. in those without it. As side effects of high-dose chemotherapy, symptoms of the digestive system and hair loss were observed in all cases, but marked leukopenia and thrmbopenia recovered rapidly after the 2nd week after ABMT.

  17. Microwave Ablation in Combination with Chemotherapy for the Treatment of Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    PurposeTo verify whether microwave ablation (MWA) used as a local control treatment had an improved outcome regarding advanced non-small cell lung cancer (NSCLC) when combined with chemotherapy.MethodsThirty-nine patients with histologically verified advanced NSCLC and at least one measurable site other than the ablative sites were enrolled. Primary tumors underwent MWA followed by platinum-based doublet chemotherapy. Modified response evaluation criteria in solid tumors (mRECIST) and RECIST were used to evaluate therapeutic response. Complications were assessed using the National Cancer Institute Common Toxicity Criteria (version 3.0).ResultsMWA was administered to 39 tumors in 39 patients. The mean and median diameters of the primary tumor were 3.84 cm and 3.30 cm, respectively, with a range of 1.00–9.00 cm. Thirty-three (84.6 %) patients achieved a partial response. No correlation was found between MWA efficacy and clinicopathologic characteristics. For chemotherapy, 11 patients (28.2 %) achieved a partial response, 18 (46.2 %) showed stable disease, and 10 (25.6 %) had progressive disease. The overall objective response rate and disease control rate were 28.2 and 74.4 %, respectively. The median progression-free survival time was 8.7 months (95 % CI 5.5–11.9). The median overall survival time was 21.3 months (95 % CI 17.0–25.4). Complications were observed in 22 (56.4 %) patients, and grade 3 adverse events were observed in 3 (7.9 %) patients.ConclusionsPatients with advanced NSCLC could benefit from MWA in combination with chemotherapy. Complications associated with MWA were common but tolerable

  18. Treatment of small cell carcinoma of lung with combined high dose mediastinal irradiation, whole brain prophylaxis and chemotherapy

    International Nuclear Information System (INIS)

    Survival of patients with small cell carcinoma of lung, treated on a new combined radiotherapy-chemotherapy protocol, compares favorably with other regimens in the literature and our own previous combined approaches. Radiation, given after induction chemotherapy, consisted of whole brain prophylaxis in all 44 evaluable patients. Patients with limited disease were also treated to the primary and mediastinum to a high dose (5000 rad equivalent) using multiple fields. The new chemotherapy regimen consisted of induction with cyclophosphamide, doxorubicin, and vincristine alternated with cis-platinum and VP-16 (an epipodophyllotoxin) for two cycles, followed by consolidation with low dose cyclophosphamide and vincristine concurrent with irradiation. Patients with limited disease who achieved less than complete response, and all patients with extensive disease were not continued on maintenance chemotherapy. Out of 24 evaluable patients with limited disease, there was 73% survival at 1 year by life-table analysis, measured from treatment initiation. After induction, 16/24 of these limited disease patients were CR (complete responders): 20/24 were CR at completion of their irradiation. Out of 20 evaluable patients with extensive disease, there was 59% survival at 1 year by life-table analysis. Only 4/44 (9%) brain parenchymal relapses occurred, one at 3 months and one at 6 months after local failure and two in patients who did not become CRs, implicating a possible re-seeding mechanism. Five patients had central nervous system relapses outside of brain parenchyma (spinal epidural and leptomeningeal); in three patients this was the initial site of failure. Significant complications included leukopenia (50%) and thrombocytopenia (24%) primarily during induction, and chronic pulmonary fibrosis (25%), possibly contributing to two deaths

  20. Sequencing chemotherapy and radiotherapy in locoregional advanced breast cancer patients after mastectomy – a retrospective analysis

    International Nuclear Information System (INIS)

    Combined chemo- and radiotherapy are established in breast cancer treatment. Chemotherapy is recommended prior to radiotherapy but decisive data on the optimal sequence are rare. This retrospective analysis aimed to assess the role of sequencing in patients after mastectomy because of advanced locoregional disease. A total of 212 eligible patients had a stage III breast cancer and had adjuvant chemotherapy and radiotherapy after mastectomy and axillary dissection between 1996 and 2004. According to concerted multi-modality treatment strategies 86 patients were treated sequentially (chemotherapy followed by radiotherapy) (SEQgroup), 70 patients had a sandwich treatment (SW-group) and 56 patients had simultaneous chemoradiation (SIM-group) during that time period. Radiotherapy comprised the thoracic wall and/or regional lymph nodes. The total dose was 45–50.4 Gray. As simultaneous chemoradiation CMF was given in 95.4% of patients while in sequential or sandwich application in 86% and 87.1% of patients an anthracycline-based chemotherapy was given. Concerning the parameters nodal involvement, lymphovascular invasion, extracapsular spread and extension of the irradiated region the three treatment groups were significantly imbalanced. The other parameters, e.g. age, pathological tumor stage, grading and receptor status were homogeneously distributed. Looking on those two groups with an equally effective chemotherapy (EC, FEC), the SEQ- and SW-group, the sole imbalance was the extension of LVI (57.1 vs. 25.6%, p < 0.0001). 5-year overall- and disease free survival were 53.2%/56%, 38.1%/32% and 64.2%/50%, for the sequential, sandwich and simultaneous regime, respectively, which differed significantly in the univariate analysis (p = 0.04 and p = 0.03, log-rank test). Also the 5-year locoregional or distant recurrence free survival showed no significant differences according to the sequence of chemo- and radiotherapy. In the multivariate analyses the sequence had no

    2014-01-01

    Chemotherapy given in a metronomic manner can be administered with less adverse effects which are common with conventional schedules such as myelotoxicity and gastrointestinal toxicity and thus may be appropriate for older patients and patients with decreased performance status. Efficacy has been observed in several settings. An opportunity to improve the efficacy of metronomic schedules without significantly increasing toxicity presents with the addition of anti-angiogenic targeted treatment...

    The nonsurgical strategies for locally advanced oral cancer are desirable. Superselective intra-arterial infusion with radiotherapy was utilized for this purpose, and there are two types of superselective intra-arterial infusion methods: The Seldinger method and the retrograde superselective intra-arterial chemotherapy (HFT method). In one case, the HFT method was applied to locally advanced tongue cancer, and the Seldinger method was used for additional administration of cisplatin (CDDP) to ...

  3. Combined chemotherapy and irradiation therapy after radical surgery for leiomyosarcoma of the vulva

    International Nuclear Information System (INIS)

    Radical surgery failed to remove a leiomyosarcoma of the vulva completely, and residual tumour was left. Chemotherapy did not inhibit further local growth or the occurrence of secondary lesions in the lung. Irradiation therapy of the pelvis, including the area of the tumour, then successfully inhibited any further local growth, as evidenced by a marked decrease in size and eventual disappearance of the mass; however, the patient succumbed to distant metastasis

  4. Concepts and mechanisms underlying chemotherapy induced immunogenic cell death: impact on clinical studies and considerations for combined therapies.

    2015-12-01

    Chemotherapy has historically been thought to induce cancer cell death in an immunogenically silent manner. However, recent studies have demonstrated that therapeutic outcomes with specific chemotherapeutic agents (e.g. anthracyclines) correlate strongly with their ability to induce a process of immunogenic cell death (ICD) in cancer cells. This process generates a series of signals that stimulate the immune system to recognize and clear tumor cells. Extensive studies have revealed that chemotherapy-induced ICD occurs via the exposure/release of calreticulin (CALR), ATP, chemokine (C-X-C motif) ligand 10 (CXCL10) and high mobility group box 1 (HMGB1). This review provides an in-depth look into the concepts and mechanisms underlying CALR exposure, activation of the Toll-like receptor 3/IFN/CXCL10 axis, and the release of ATP and HMGB1 from dying cancer cells. Factors that influence the impact of ICD in clinical studies and the design of therapies combining chemotherapy with immunotherapy are also discussed. PMID:26486085

  5. Metallic stent implantation combined with intra-arterial chemotherapy for the treatment of malignant gastric and duodenal obstruction

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical effect of metallic stent implantation together with intra-arterial chemotherapy in treating malignant gastric and duodenal obstruction. Methods: A total of 32 patients with malignant gastric and duodenal obstruction were enrolled in this study. The obstructed sites were located at the gastric sinus and pylorus part (n=16), at the gastroduodenal anastomotic stoma (n=6) or at the descending part of duodenum (n=10). Under DSA guidance and with the additional help of endoscopy, a guide-wire was orally placed in the gastroduodenal obstructed site, which was followed by the implantation of the self-expanding metallic stent (Ni-Ti alloy). Postoperative intra-arterial chemotherapy via the tumor-feeding arteries was carried out in 16 patients (dual interventional therapy). The clinical results were analyzed. Results: Successful stent insertion was achieved in all 32 patients (100%). After stent implantation the obstructive symptoms were markedly relieved and the food intake was improved. No serious complications occurred. The median survival time for the 16 patients who had received dual interventional therapy was 9.3 months, while the median survival time for the other 16 patients who had received simple stenting therapy was 5.7 months. Conclusion: For the treatment of inoperable malignant gastroduodenal obstruction, the implantation of metallic self-expanding stents is a technically simple, clinically safe and effective palliative measure. Combined with postoperative intra-arterial chemotherapy, the metal stent implantation can control the tumor growth and elongate the survival time. (authors)

  6. Chemotherapy combined with involved-field radiotherapy for 177 children with Hodgkin's disease treated in 1983-1987

    International Nuclear Information System (INIS)

    During the period from 1983 through 1987, a total of 177 children with biopsy proven Hodgkin's disease have undergone chemotherapy combined with local irradiation. The patients were divided into low, middle, and high stage groups. MVPP chemotherapy, consisting of mechlorethamine, vinblastine, procarbazine, and prednisone, was given as the basic treatment. B-DOPA chemotherapy, consisting of bleomycin, dacarbazine, vincristine, prednisone, and adriamycin, was given to some children. Irradiation was limited to involved regions by cobalt therapy for 114 patients and by conventional radiotherapy for 56 patients. In the remaining 7 patients, radiotherapy was given to peripheral lymph nodes and cobalt therapy to mediastinal tumor and/or abdomen. Irradiation doses ranged from 30 to 40 Gy in most of the patients. One hundred and seventy five patients (98.9%) had complete remission (CR). The probability for 5-year disease-free survival and survival was 0.91 and 0.98, respectively. The most common hematological complication was leukopenia. Relapse occurred in a total of 15 patients (8.5%) within 4-48 months after establishing the first CR: it was the most frequent in the middle stage group (8 patients). Seven patients died: 4 died as a result of complications and the other 3 died during the first CR. (N.K.)

    Full Text Available Abstract Background Breast cancer is the first cancer in women both in incidence and mortality. The treatment of breast cancer benefited from the progress of chemotherapy and targeted therapies, but there was a parallel increase in treatment costs. Despite a relatively high incidence of many sites of cancer, so far, there is no national register for this disease in Morocco. The main goal of this paper is to estimate the total cost of chemotherapy in the early stages of breast cancer due to its frequency and the chances of patients being cured. This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of antimitotics and trastuzumab in Morocco. Method We start by evaluating the individual cost according to the therapeutic sub-groups, namely: 1. Patients needing chemotherapy with only anthracycline-based therapy. 2. Patients needing chemotherapy with both anthracycline and taxane but without trastuzumab. 3. Patients needing trastuzumab in addition to chemotherapy. For each sub-group, the protocol of treatment is described, and the individual costs per unit, and for the whole cycle, are evaluated. Then we estimate the number of women suffering from breast cancer on the basis of two data bases available in Morocco. Finally, we calculate the total annual cost of treatment of breast cancer in Morocco. Results The total cost of breast cancer in Morocco is given in Moroccan dirhams (MAD, the US dollar at the current exchange rate (MAD 10 = USD 1.30 and in international dollars or purchasing power parity (MAD 10 = PPP 1.95. The cost of a therapy with trastuzumab is 8.4 times the cost of a sequential chemotherapy combining anthracycline and taxane, and nearly 60 times the cost of chemotherapy based on anthracycline alone. Globally, between USD 13.3 million and USD 28.6 million need to be devoted every year by the Moroccan health authorities to treat

    The purpose of this study was to determine the histopathologic therapeutic effects in metastatic bone marrow for various therapy in cancer patients. Autopsy cases at Shikoku Cancer Center Hospital, mainly cancer of breast, stomach, lung and prostate examined radiotherapy (28-60 Gy) and chemotherapy and/or endocrine chemotherapy (medroxyprogesterone acetate, tamoxifen). Histological evaluation of effects for radio-and chemotherapy have been criteria of UICC and criteria for the evaluation of the clinical and pathological effects by Japan Society for Cancer Therapy. The precise effects for various therapy is difficult to measure objectively in metastatic bone. Histopathologic changes of metastatic bone marrow for radiotherapy revealed decrease and degeneration of tumor cells - swelling, vacuoles of cytoplasm and nuclei, bizarre and giant multinucleated giant cells etc. Stromal reaction was found postnecrotic fresh and/or old granulation-fibrosis and hyalinization, woven bone formation and fatty marrow. Systemic therapy of breast cancer revealed stromal fibrosis and chondroid ossification more than other tumors and therapy. Morphological features of metastatic bone marrow at autopsy cases may be necessary from viewpoint of therapeutic effects. (author)

    Hao Qin

    Full Text Available BACKGROUND: Some investigations have suggested that induction chemotherapy with a combination of taxanes, cisplatin and fluorouracil (TPF is effective in locally advanced head and neck cancer. However, other trials have indicated that TPF does not improve outcomes. The objective of this study was to compare the efficacy and safety of TPF with a cisplatin and fluorouracil (PF regimen through a meta-analysis. METHODS: Four randomized clinical trials were identified, which included 1,552 patients with locally advanced head and neck cancer who underwent induction chemotherapy with either a TPF or PF protocol. The outcomes included the 3-year survival rate, overall response rate and different types of adverse events. Risk ratios (RRs and their 95% confidence intervals (CIs were pooled using RevMan 5.1 software. RESULTS: The 3-year survival rate (51.0% vs. 42.4%; p = 0.002, 3-year progression-free survival rate (35.9% vs. 27.2%; p = 0.007 and overall response to chemotherapy (72.9% vs. 62.1%; p<0.00001 of the patients in the TPF group was statistically superior to those in the PF group. In terms of toxicities, the incidence of febrile neutropenia (7.0% vs. 3.2%; p = 0.001 and alopecia (10.8% vs. 1.1%; p<0.00001 was higher in the TPF group. CONCLUSION: The TPF induction chemotherapy regimen leads to a significant survival advantage with acceptable toxicity rates for patients with locally advanced head and neck cancer compared with the PF regimen.

  10. Evaluation of docetaxel, CDDP and 5-FU combined therapy as second-line chemotherapy for esophagus cancer

    The combined therapy of docetaxel (70 mg/m2, day 1) cisplatin (CDDP) (80 mg/m2, day 1) and 5- fluorouracil (FU) (800 mg/m2, day 1-5) is used as second-line chemotherapy for esophagus cancer. First-line chemotherapy for 32 advanced squamous cell carcinomas of the esophagus is not effective, and early recurrences after chemotherapy were examined. Pretreatment surgery was used in 20 cases, radiation therapy in 19 and chemotherapy by 3.1 courses (1-9) on average. PR was found in 16 patients (response rate 50%) in the first course, MR in 2, NC in 6, and PD in 7 cases. Among 16 patients, one was of HCM patients. (auaspiration pneumonia and two by leukopenia. Thirteen patients received 3-5 courses. The operation was continuously enforced in three patients among 13, radiation therapy was added in three, and they survived for one year or more. Five for whom imaging became virtually impossible lived for six months or more. Additional treatment proved ineffective in 2, so it was discontinued. There were 18 lymph node examples of lesions effectively treated, 6 main lesions, 1 pulmonary metastasis and 1 bone metastasis. As for deleterious events, leukopenia was admitted in 95%. Granulocyte-colony stimulating factor (G-CSF) was needed by 68% during use and 3 days on average. The CDDP+5-FU+docetaxel therapy was comparatively safe in patients with much pre-treatment and demonstrated a maximum effect at more than the expected rate. (author)

  11. Bladder cancer: The combination of chemotherapy and irradiation in the treatment of patients with muscle-invading tumors

    International Nuclear Information System (INIS)

    In the USA the recommended treatment for patients with muscle-invading transitional cell cancer of the bladder is usually radical cystectomy. Conservative surgery irradiation, and cisplatin-based systemic chemotherapy are, however, each effective for some patients. Although they provide the opportunity for bladder preservation, each modality, when used alone, is inferior to radical cystectomy in terms of local control and, perhaps, survival. Many recent publications have now documented the efficacy of combined modality treatment protocols employing all three of these modalities together. All employ a selective approach in which the patients only receive full-dose radiation if they have had a complete response to induction CMT. Overall survival data for T2-T3a patients are certainly as good as any reported cystectomy series of similarly clinically staged and similar aged patients. Radiation adds very significantly to the transurethral resection and systemic chemotherapy to maintain the bladder free of tumor. Substantially higher rates of pathologic confirmation of complete response are found following transurethral surgery and chemoradiation when compared with transurethral surgery and chemotherapy omitting the radiation. Overall survival is as good as cystectomy based approaches at 48-54% and over 80% of these long-term survivors keep their bladders. Following such therapies, 20-30% will subsequently develop superficial tumors. These patients may still be well treated by standard methods using transurethral resection and intravesical drugs. The concern of urologists that the conserved irradiated bladder functions poorly has also been answered by recent reports using modern radiation techniques. The instance of cystectomy for bladder shrinkage is repeatedly below 2%. Furthermore, sexual function is commonly preserved. The systemic morbidity of the chemotherapy is relatively high, but new approached using anti-emetics and GCSF now allow this to be reduced. In many

    AIM: To compare the effect, adverse events, cost-effectiveness and dose intensity (DI) of oral Xeloda vs calcium folinate (CF)/5-FU combination chemotherapy in patients with advanced gastrointestinal malignancies, both combined with bi-platinu two-way chemotherapy.METHODS: A total of 131 patients were enrolled and randomly selected to receive either oral Xeloda (X group)or CF/5-FU (control group). Oral Xeloda 1 000 mg/m2was administered twice daily from d 1 to 14 in X group,while CF 200 mg/m2 was taken as a 2-h intravenous infusion followed by 5-FU 600 mg/m2 intravenously for 4-6 h on d 1-5 in control group. Cisplatin and oxaliplatin were administered in the same way to both the groups:cisplatin 60-80 mg/m2 by hyperthermic intraperitoneal administration, and oxaliplatin 130 mg/m2 intravenously for 2 h on d 1. All the drugs were recycled every 21 d,with at least two cycles. Pyridoxine 50 mg was given t.i.d.orally for prophylaxis of the hand-foot syndrome (HFS).Then the effect, adverse events, cost-effectiveness and DI of the two groups were evaluated.RESULTS: Hundred and fourteen cases (87.0%) finished more than two chemotherapy cycles. The overall response rate of them was 52.5% (X group) and 42.4% (control group) respectively. Tumor progression time (TTP) was 7.35 mo vs5.95 mo, and 1-year survival rate was 53.1% vs 44.5%. There was a remarkable statistical significance of TTP and 1-year survival between the two groups. The main Xeloda-related adverse events were myelosuppression,gastrointestinal toxicity, neurotoxicity and HFS, which were mild and well tolerable. Therefore, no patients withdrew from the study due to side effects before two chemotherapy cycles were finished. Both groups finished pre-arranged DI and the relative DI was nearly 1.0. The average cost for 1 patient in one cycle was $9 137.35(X group) and $8 961.72 (control group), or US $1 100.89in X group and $1 079.73 in control group. To add 1% to the response rate costs $ 161.44 vs $210

    Objective To investigate whether high-intensity focused ultrasound (HIFU) combined with microbubbles enhances the therapeutic effects of chemotherapy. Materials and Methods A pancreatic cancer xenograft model was established using BALB/c nude mice and luciferase-expressing human pancreatic cancer cells. Mice were randomly assigned to five groups according to treatment: control (n = 10), gemcitabine alone (GEM; n = 12), HIFU with microbubbles (HIFU + MB, n = 11), combined HIFU and gemcitabine (HIGEM; n = 12), and HIGEM + MB (n = 13). After three weekly treatments, apoptosis rates were evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay in two mice per group. Tumor volume and bioluminescence were monitored using high-resolution 3D ultrasound imaging and in vivo bioluminescence imaging for eight weeks in the remaining mice. Results The HIGEM + MB group showed significantly higher apoptosis rates than the other groups (p < 0.05) and exhibited the slowest tumor growth. From week 5, the tumor-volume-ratio relative to the baseline tumor volume was significantly lower in the HIGEM + MB group than in the control, GEM, and HIFU + MB groups (p < 0.05). Despite visible distinction, the HIGEM and HIGEM + MB groups showed no significant differences. Conclusion High-intensity focused ultrasound combined with microbubbles enhances the therapeutic effects of gemcitabine chemotherapy in a pancreatic cancer xenograft model. PMID:27587968

    Therapeutic anticancer vaccine development must address a number of barriers to achieve successful tumor specific killing, including effective antigen presentation and antigen-specific T-cell activation to mediate cytotoxic cellular effects, inhibition of an immune-suppressive tumor microenvironment in order to facilitate and enhance CTL activity, and induction of memory T-cells to prolong tumor rejection. While traditional as well as modern vaccines rely upon delivery of both antigen and adjuvant, a variety of clinically relevant cancers lack ideal immunogenic antigens. Building upon recent efforts, we instead chose to exploit chemotherapy-induced apoptosis to allow for in situ antigen generation in a combination, nanomedicine-based approach. Specifically, lipid-coated cisplatin nanoparticles (LPC) and CpG-encapsulated liposomes (CpG-Lipo) were prepared for the temporally-controlled and multifaceted treatment of an advanced in vivo model of melanoma. Such combination therapy established strong synergistic effects, both in apoptotic extent and subsequent abrogation of tumor growth, which were due largely to both an enhanced cytotoxic T-cell recruitment and a reduction of immune-suppressive mediators in the microenvironments of both spleens and tumor. These results underlie a prolonged host lifespan in the combination approach (45 days) as compared with control (25 days, p < 0.02), providing promise toward a personalized approach to nanomedicine by establishing effect synergy in host-specific immunotherapy following chemotherapy.

    Merkel cell carcinoma (MCC) is a rare, but highly malignant tumor of the skin. In case of systemic disease, possible therapeutic options include irradiation or chemotherapy. The aim of this study was to evaluate whether the flavonoid resveratrol enhances the effect of radiotherapy or chemotherapy in MCC cell lines. The two MCC cell lines MCC13 and MCC26 were treated with increasing doses of resveratrol. Combination experiments were conducted with cisplatin and etoposide. Colony forming assays were performed after sequential irradiation with 1, 2, 3, 4, 6, and 8 Gy and apoptosis was assessed with flow cytometry. Expression of cancer drug targets was analyzed by real-time PCR array. Resveratrol is cytotoxic in MCC cell lines. Cell growth is inhibited by induction of apoptosis. The combination with cisplatin and etoposide resulted in a partially synergistic inhibition of cell proliferation. Resveratrol and irradiation led to a synergistic reduction in colony formation compared to irradiation alone. Evaluation of gene expression did not show significant difference between the cell lines. Due to its radiosensitizing effect, resveratrol seems to be a promising agent in combination with radiation therapy. The amount of chemosensitizing depends on the cell lines tested. (orig.)

  20. Defect in assimilation following combined radiation and chemotherapy in patients with locally unresectable pancreatic carcinoma

    International Nuclear Information System (INIS)

    The relative contributions of high-dose irradiation and/or chemotherapy to the nutritional problems of patients with inoperable pancreatic carcinoma were evaluated by study of pancreatic exocrine function and jejunal function and morphologic findings in ten patients before and after treatment. Nutrient assimilation studies included determination of serum carotene levels, D-xylose absorption and fat absorption. Crosby capsule biopsy specimen of jejunal mucosa were evaluated with light microscopy. Fat assimilation was the only parameter of nutritional function to significantly worsen after therapy. Low serum carotene levels present in the patients before therapy remained low but did not significantly change after treatment. D-xylose absorption and the morphologic structure of the jejunal mucosa were normal before and after treatment. These findings support the previous observations that the nutritional problems of the patient with inoperable pancreatic carcinoma are due to pancreatic insufficiency and that high dose irradiation and chemotherapy can exacerbate the pancreatic insufficiency but do not produce jejunal dysfunction. Therefore, it is suggested that pancreatic exocrine replacement therapy may improve the nutritional status of these patients

    Full Text Available Surgery is the most effective therapy for cancer in the United States, but disease still recurs in more than 40% of patients within 5 years after resection. Chemotherapy is given postoperatively to prevent relapses; however, this approach has had marginal success. After surgery, recurrent tumors depend on rapid neovascular proliferation to deliver nutrients and oxygen. Phosphatidylserine (PS is exposed on the vascular endothelial cells in the tumor microenvironment but is notably absent on blood vessels in normal tissues. Thus, PS is an attractive target for cancer therapy after surgery. Syngeneic mice bearing TC1 lung cancer tumors were treated with mch1N11 (a novel mouse chimeric monoclonal antibody that targets PS, cisplatin (cis, or combination after surgery. Tumor relapses and disease progression were decreased 90% by combination therapy compared with a 50% response rate for cis alone (P = .02. Mice receiving postoperative mch1N11 had no wound-related complications or added systemic toxicity in comparison to control animals. Mechanistic studies demonstrated that the effects of mch1N11 were associated with a dense infiltration of inflammatory cells, particularly granulocytes. This strategy was independent of the adaptive immune system. Together, these data suggest that vascular-targeted strategies directed against exposed PS may be a powerful adjunct to postoperative chemotherapy in preventing relapses after cancer surgery.

    Full Text Available Papillary serous carcinoma of the uterine cervix (PSCC is a very rare tumor, and is a recently described variant of cervical adenocarcinoma. We experienced a case of stage IV PSCC. The main tumor existed in the uterine cervix and invaded one third of the inferior part of the anterior and posterior vaginal walls. Furthermore, it had metastasized from the para-aortic lymph nodes to bilateral neck lymph nodes. Immnoreactivity for CA125 was positive, whereas the staining for p53 and WT-1 were negative in both the original tumor and the metastatic lymph nodes. We administered six courses of paclitaxel and carboplatin combination chemotherapy against this advanced PSCC. The PSCC therefore dramatically decreased in size. The main tumor of the uterine cervix showed a complete response by magnetic resonance imaging (MRI, and more than 95% of the tumor cells in the cervix had microscopically disapperared. This is the first report of PSCC in which combination chemotherapy was used and showed a remarkable response.

    A simple PEGylated peptidic nanocarrier, PEG5000-lysyl-(α-Fmoc-ε-Cbz-lysine)2 (PLFCL), was developed for effective co-delivery of doxorubicin (DOX) and dasatinib (DAS) for combination chemotherapy. Significant synergy of DOX and DAS in inhibition of cancer cell proliferation was demonstrated in various types of cancer cells, including breast, prostate, and colon cancers. Co-encapsulation of the two agents was facilitated by incorporation of 9-Fluorenylmethoxycarbonyl (Fmoc) and carboxybenzyl (Cbz) groups into a nanocarrier for effective carrier-drug interactions. Spherical nanomicelles with a small size of ∼30 nm were self-assembled by PLFCL. Strong carrier/drug intermolecular π-π stacking was demonstrated in fluorescence quenching and UV absorption. Fluorescence study showed more effective accumulation of DOX in nuclei of cancer cells following treatment with DOX&DAS/PLFCL in comparison with cells treated with DOX/PLFCL. DOX&DAS/PLFCL micelles were also more effective than other treatments in inhibiting the proliferation and migration of cultured cancer cells. Finally, a superior anti-tumor activity was demonstrated with DOX&DAS/PLFCL. A tumor growth inhibition rate of 95% was achieved at a respective dose of 5 mg/kg for DOX and DAS in a murine breast cancer model. Our nanocarrier may represent a simple and effective system that could facilitate clinical translation of this promising multi-agent regimen in combination chemotherapy. PMID:26210177

  6. Clinical trial of neoadjuvant chemotherapy combined with radiotherapy for primary intracranial germinomas

    International Nuclear Information System (INIS)

    Purpose/Objective: Since 1992, we have been using neoadjuvant chemotherapy to reduce the radiation dose and irradiated volume in the treatment of intracranial germinomas. This study evaluates the initial response and complications of the treatment and also the IQ score and pituitary function of patients before radiotherapy. Materials and methods: Fifteen patients with histologically confirmed intracranial germinomas were treated between 1992 and 1997. Six patients with solitary pure germinoma received 3 to 4 courses of etoposide and cisplatin (EP regimen) followed by localized irradiation of 24Gy (in 12 fractions within 3 weeks). Three patients with germinoma with syncytiotrophoblastic giant cells (STGC) and 4 patients with multifocal pure germinoma received 3 to 5 courses of ifosfamide, cisplatin and etoposide (ICE regimen), followed by localized irradiation of 24 Gy. Two patients with disseminated pure germinoma received 2 to 4 courses of ICE regimen followed by craniospinal irradiation of 24 Gy. In the planning of localized irradiation, the treatment field was determined so as to cover the tumor with a margin of 2cm. The IQ score and pituitary function before radiotherapy were also examined. MRI was performed in all patients one month after the completion of treatment and every 6 months in the follow-up study. The treatment data of our institute before 1991, as historical control, was analyzed and compared to that of the present study. Results: Complete remission (CR) was obtained in all patients after the treatment. One patient with germinoma with STGC experienced recurrence out of the field at 39 months after surgery. He was re-treated with salvage therapy including the ICE regimen and obtained a second complete remission. All patients are alive without disease with a median follow-up period of 29 months. The examination of IQ score and pituitary function before radiotherapy revealed mental retardation in 2 patients (22%) and hypopituitarism in 13 patients (86

  7. Radiotherapy in combination with simultaneous intra-arterial chemotherapy (RADPLAT) in patients with advanced head and neck cancer

    International Nuclear Information System (INIS)

    A particular challenge for both laryngologists and oncologists is presented by the fact that treatment of patients in advanced stages of cancer disease, in whom either combined therapy (surgery and adjuvant radiotherapy) or radiotherapy alone have been applied, is associated with highly dissatisfying results. Clinical trials exploring the application of chemotherapy combined with simultaneous radiotherapy are arousing greater interest. This is because the results of recently published randomised prospective studies and meta analyses show improved loco-regional results of this treatment strategy, which in turn improves overall survival. Cytostatic drugs used in conjunction with radiotherapy have many functions but, above all, their purpose is to intensify the effects of irradiation which, in such treatment schemes, is the leading method. One of the basic factors limiting the application of such strategies is the problem of how to limit the toxicity from one side, while administering a sufficiently high dose of cytostatics, and to continue without any gaps the course of radiation from the other. A problem associated with combined therapy is how to ensure the highest concentration of cytostatics is in the malignant tumour. The need to break through both of these limiting factors has become the subject of intensive research. One of the possible solutions to these problems is the simultaneous application of irradiation in combination with selective intra-arterial chemotherapy. To date, final results are still unavailable from phase III clinical trials which are investigating this treatment method. Presented in this paper are the advantages and disadvantages in the treatment strategy called the RADPLAT programme. The RADPLAT programme is characterised by great local effects, somewhat lesser regional effects and still lesser effects in the treatment of micro-metastases. Research is continuing, in order to find methods for the improvement of treatment results, with a view

    The nonparametric combination of dependent permutation tests method is a useful general tool when a testing problem can be broken down into a set of different k > 1 partial tests. These partial tests, after adjustment of p-values to control for multiplicity, can be marginally analyzed, but jointly considered they can provide information on an overall hypothesis, which might represent the true goal of the testing problem. On the one hand, independence among the partial tests is usually an unrealistic assumption; on the other, even when the underlying dependence relations are known quite often they are difficult to cope with properly. Therefore this combination must be achieved nonparametrically, by implicitly taking into account the dependence structure of tests without explicitly describing it. An important property of the tests based on nonparametric combination methodology, when the number of response variables is high compared to the sample sizes, consists in the finite sample consistency. A practical problem involves choosing the most suitable combining function for each specific testing problem given that the final result can be affected by this crucial choice. The purpose of this article is to present an nonparametric combination solution based on the iterated combination of partial tests, evaluate its power behavior using a Monte Carlo simulation study and apply it to a real medical problem, namely the evaluation of the effects of chemotherapy on the shape of esophageal tumors. R code has been implemented to carry out the analyses. PMID:23070597

    Purpose: Long-term survival rates for patients with resected pancreatic ductal adenocarcinoma (PDAC) have stagnated at 20% for more than a decade, demonstrating the need to develop novel adjuvant therapies. Gemcitabine-erlotinib therapy has demonstrated a survival benefit for patients with metastatic PDAC. Here we report the first phase 2 study of erlotinib in combination with adjuvant chemoradiation and chemotherapy for resected PDAC. Methods and Materials: Forty-eight patients with resected PDAC received adjuvant erlotinib (100 mg daily) and capecitabine (800 mg/m{sup 2} twice daily Monday-Friday) concurrently with intensity modulated radiation therapy (IMRT), 50.4 Gy over 28 fractions followed by 4 cycles of gemcitabine (1000 mg/m{sup 2} on days 1, 8, and 15 every 28 days) and erlotinib (100 mg daily). The primary endpoint was recurrence-free survival (RFS). Results: The median follow-up time was 18.2 months (interquartile range, 13.8-27.1). Lymph nodes were positive in 85% of patients, and margins were positive in 17%. The median RFS was 15.6 months (95% confidence interval [CI], 13.4-17.9), and the median overall survival (OS) was 24.4 months (95% CI, 18.9-29.7). Multivariate analysis with adjustment for known prognostic factors showed that tumor diameter >3 cm was predictive for inferior RFS (hazard ratio, 4.01; P=.001) and OS (HR, 4.98; P=.02), and the development of dermatitis was associated with improved RFS (HR, 0.27; P=.009). During CRT and post-CRT chemotherapy, the rates of grade 3/4 toxicity were 31%/2% and 35%/8%, respectively. Conclusion: Erlotinib can be safely administered with adjuvant IMRT-based CRT and chemotherapy. The efficacy of this regimen appears comparable to that of existing adjuvant regimens. Radiation Therapy Oncology Group 0848 will ultimately determine whether erlotinib produces a survival benefit in patients with resected pancreatic cancer.

    Primary squamous cell colorectal carcinomas are uncommon, and their characteristics are not well known. They seem to occur most commonly in the fifth decade of life with a slight predominance for men. The most commonly reported anatomic locations are the rectum and the proximal colon. Clinical features and common diagnostic methods do not easily differentiate squamous cell colorectal carcinomas from adenocarcinomas. Because of their extremely rare occurrence, it is difficult to study their natural course, clinical behavior, and response to therapy. This report presents the case of a pure squamous cell colorectal cancer and provides a brief review of the literature, which includes 60 previously published cases. The case of a patient with T3N2M0 primary squamous cell carcinoma of the rectosigmoid colon, which was initially treated with abdominoperineal resection followed by adjuvant chemotherapy and radiation, is presented. During the follow-up, an elevated squamous cell carcinoma antigen (SCC Ag) level led to restaging computed tomography scans, which confirmed recurrent metastatic disease in the liver. Response to chemotherapy with a decrease in tumor size correlated with a decrease in the serum SCC Ag level. Although SCC Ag has been used as a tumor marker for squamous cell cancers of the lung, head and neck, uterine cervix, and esophagus, this is the first reported case of a squamous cell colon carcinoma presenting with an elevated SCC Ag at the time of recurrence. In addition, this patient showed an objective partial response to combination chemotherapy, with a decrease in the serum level of this tumor marker. PMID:12445380

    This study assesses the outcome of two combined treatment strategies for the treatment of feline injection-site sarcoma (FISS). Twenty-one cats with primary or recurrent FISS received 3 cycles of neoadjuvant chemotherapy with epirubicin (25 mg m(-2) ), then an anatomical resection of the entire muscle compartment containing the tumour was performed based on the findings of co-axial imaging. Cats then received a further 3 cycles of adjuvant chemotherapy. Follow-up was performed by telephone contact with a median follow-up time of 1072 days. Three cats (14%) developed local tumour recurrence at days 264, 664 and 1573 after surgery. A median survival time could not be calculated as over 80% of the study population remained alive or were censored due to death from other causes. When compared to historical controls, the results of this study demonstrate superior rates of tumour-free survival and disease-free interval. PMID:24502401

    International Nuclear Information System (INIS)

    Sixty-four consecutive patients with inoperable epidermoid bronchogenic carcinoma (limited disease) were treated with radiotherapy to the primary and nodal areas and combination chemotherapy with cyclophosphamide, adriamycin, methotrexate and procarbazine. The overall response rate (CR + PR) to combined treatment was 62%. The median survival time was 12.7 months. The toxicity was acceptable and no treatment-related death occurred

  14. 125I brachytherapy combined with chemotherapy for patients with inoperable stage III non-small cell lung cancer

    Objective: To assess the therapeutic effect of radioactive seed 125I brachytherapy combined with GP chemotherapy regimen (gemcitabine 1000 mg/m2, cisplatin 75 mg/m2) for inoperable stage III non-small cell lung cancer (NSCLC). Methods: Thirty-nine documented inoperable stage III NSCLC patients, enrolled between January 2005 and June 2008 for the study group, were treated with the combination of 125I brachytherapy and GP regimen. The brachytherapy methods were conducted according to TPS and each patient was treated under those patients were treated with standard GP regimen. Chest CT scans were performed every three months post-procedurally, until disease progression or recurrence. The follow-up time was up to twenty four months after treatment. In the control group, equal amount of III stage NSCLC patients were treated with standard GP regimen alone. Chi-square test and survival analysis with Kaplan-Meier and Log-rank were used to compare the differences of recent (3 months after therapy) efficiency, survival rate, survival time between two groups. Results: The re-cent effective rates of the study group (71.8%, 28/39) and control group (61.5%, 24/39) were not statistical different (χ2=0.93, P>0.05), yet the tumor CR rates in two groups showed significant disparity (χ2=4.48, P2=1.57, P>0.05). However, significant differences (χ2=4.07, 4.63,both P125I brachytherapy combined with GP regimen chemotherapy could be an effective treatment method and could improve the tumor CR rate and survival rate for patients with inoperable stage III NSCLC.

  15. Treatment results and complications in clinical combinations of radiation and chemotherapy in the treatment of localized cancer in the head and neck

    International Nuclear Information System (INIS)

    By using chemotherapy combined with radiotherapy, significant improvements were achieved in treatment results of localized non-Hodgkin's lymphoma, intraoral cancer, and carcinoma of the maxillary sinus. Administering chemotherapy with radiation was given sumultaneously in the patients with intraoral cancer (BLM iv) and with carcinoma of the maxillary sinus (5-FU ia). In the patients with non-Hodgkin's lymphoma, chemotherapy (1 or 2 cycles of COPP) was administered and followed by radiotherapy. If radiation dose were reduced by about 50% in the intraoral cancer, 20% in carcinoma of the maxillary sinus, and 10% in non-Hodgkin's lymphoma, acute and/or chronic complications were within tolerable limits in this series of observations, although toxicity was dose-related for both chemotherapy and radiotherapy.

  16. The combination therapy with hepatic arterial infusion chemotherapy and radiation therapy for advanced intrahepatic cholangiocarcinoma

    International Nuclear Information System (INIS)

    Intrahepatic cholangiocarcinoma is rare, usually diagnosed at the considerably advanced stage and thereby difficult for surgery. For such cases, the therapy in the title is conducted in authors' hospital, of which outcome is described herein. Stage III-IVB cases of 25 patients underwent the therapy (1996-2005). Chemotherapy was by cisplatin (CDDP)+5 fluorouracil (FU), or Epirubicin (FARM)+Mitomycin C (MMC)+5FU. Radiation therapy was performed on the vascular invasion and metastatic lymphaden and if possible, on the primary site, at total 39-50 Gy in a fractionated manner, by internal irradiation at 15 Gy (2 cases), and on bone metastasis at 25 Gy (1 case). Efficacy was evaluated by the Criteria 2004 by the Liver Cancer Study Group in Japan. Evaluation 6 months after therapy was partial response (PR) in 9 cases, standard deviation (SD) in 2, progressive disease (PD) in 13, data unavailable in 1: the efficacy rate was 36% (9/25). One-year survival was 52.5%, 2-year 43.7%, and 3-year 28.1%. The predicting prognosis factor found was significantly good in female and in cases without remote metastases and/or metastatic lymphadens around aorta. Thus the therapy was valuable to try and cooperative, multi-center study was thought necessary in future. (R.T.)

  17. Combined chemotherapy in the treatment of limited small cell lung carcinoma

    International Nuclear Information System (INIS)

    Between 1978 and 1983, 34 patients (32 evaluable) suffering from limited small cell lung carcinoma (SCLC-L) were treated following the protocol polychemotherapy (CAV) plus thoracic telecobaltotherapy and precaucional cranial irradiation (30 Gy in 2 weeks). Minimum follow-up was 30 months. After induction chemotherapy there was complete remission (CR) in 20% of cases whereas at the end of induction chemo-radiotherapy there was complete remission (CR) in 44% (p<0.05) of cases. Median duration of the responds was 12 months. Total median survival is 15 months, median NED survival 32 months (6-90 months). Seven out of 14 CR patients received consolidated thoracic radiotherapy (Rt); 6 of these survived disease-free for over 2 years. No salvage therapy carried out has proved useful. Only in one patient (3%) brain metastasis occurred. Iatric toxicity was also kept within limits of brain level. The role Rt plays in increasing the CR percentage, in drastically diminuishing the incidence of brain metastasis, in improving the quality of life by increasing the disease-free interval must be emphasized. Finally it should be noted that only CR patients have the possibility to become long survivors

  18. Combined methotrexate and high-dose vincristine chemotherapy with radiation therapy for small cell bronchogenic carcinoma

    International Nuclear Information System (INIS)

    The addition of methotrexate to a previously described regimen of cyclophosphamide, Adriamycin (doxorubicin), and high-dose vincristine (VAC) was tested in 50 evaluable patients with small cell bronchogenic carcinoma. Prophylactic whole brain radiation therapy was given during the first chemotherapy course and consolidation radiation therapy was given to the mediastinum and primary site after achieving partial or complete remission. The addition of methotrexate did not improve the incidence of complete remission as compared to a previous regimen without it. The addition of radiation therapy improved the local control rate. The high-dose vincristine in this and a previous CAV study improved the incidence of complete remission in both limited and extensive disease presentation as compared with the authors previous experience and induced an acceptable and reversible neurotoxicity. Moderate dose consolidation radiotherapy to the lung primary and mediastinum was effective in improving local control. The distinction between limited and extensive disease was found to be vague, as 22% of the patients could be shifted from one group to the other depending on definition. The evaluation of the various staging procedures indicates that bone scan gave a small number of truly abnormal tests. Isotopic brain and liver-spleen scan could be duplicated by computerized axial tomography (CAT). CAT scan of abdomen disclosed unexpected extension to the retroperitoneal nodes and adrenals

  19. Combined therapy of radiotherapy and chemotherapy (cisplatin, methotrexate and peplomycin) for esophageal cancer

    International Nuclear Information System (INIS)

    Between January 1984 and June 1989, 39 patients with esophageal cancer were treated with radiotherapy and 1-3 courses of cisplatin (80 mg/m2 iv day 1), methotrexate (40 mg/m2 iv day 2), and peplomycin (10 mg/body day 24 hours continuous subcutaneous infusion days 2-5) (Group 1). Results were compared with 35 patients treated between January 1984 and June 1989 with radiotherapy alone (Group 2). Group 1 patients had 35.9% complete response (CR) compared to Group 2 (28.6%). In stage 2, CR rate of Group 1 and Group 2 were 100% and 46.2% respectively (p<0.05). Median survival time (MST) for Group 1 (11 months) was longer than for Group 2 (7 months). Especially in stage 3, MST of Group 1 and Group 2 were 11 months and 5 months respectively (p<0.05). Radiation esophagitis and pneumonitis of Group 1 was more severe and more frequently than Group 2, but no fatal reaction occurred. These data suggest that radiotherapy with chemotherapy (cisplatin, methotrexate, and peplomycin) for esophageal cancer may improve response rate and survival. (author)

  20. 125I implantation combined with chemotherapy for treatment of local recurrent stage Ⅲ non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the associated effect of 125I implantation plus chemotherapy in local recurrent stage Ⅲ NSCLC patients. Methods: From January 2006 to January 2009, 34 patients documented with local recurrent stage Ⅲ NSCLC were divided into two groups by random number table. The treatment group was treated with 125I permanent implantation combined with DP regimen (docetaxel 60 mg/m2 + cisplatinum 75 mg/m2), while the control group received only DP chemotherapy. According to the TPS, the treatment group received CT-guided percutaneous implantation of 125I seeds with a particle activity of 2.22 ×107-2.59 × 107 Bq. The prescribed dose was in the range of 90-110 Gy and the postoperatively matched peripheral dose (mPD) and D90 were verified by TPS. The control group received a DP chemotherapy regime for 4 cycles after the procedure. This study was approved by the ethics committee,and all patients signed informed consents. The follow up time was up to disease progression. Kaplan-Meier survival analysis was used to describe the local lesion control (LLC) time and progression free survival (PFS). Log-rank test was used in the comparison of the survival rates between the two groups. Fisher's exact test was used to analyze the differences of CR rate and recent efficiency between two groups. Results: In the treatment group, postoperative mPD was 93.9-130.4 (M 116.7) Gy, and D90 was 103.6-148.2 (M 130.6) Gy. The LLC time was 4.7 to 24.0 months with a median of 11.6 (95% CI: 8.7-14.6) months. In two cases, there was no recurrence during the follow-up time of 24 months.PFS was 4.7 to 24.0 months with a median of 10.5 (95% CI: 7.4-13.6) months. The recent effective rate of the treatment group was 64.7% (11/17).CR, PR, SD and PD were 41.2% (7/17), 23.5% (4/17), 23.5% (4/17) and 11.8% (2/17), respectively. In the control group, the LLC time was 4.5 to 11.4 months with a median of 7.5 (95 % CI: 6.7-8.3) months, and the median of PFS was 6.5 (4.5-10.5) (95% CI: 5

    Tellurium-containing photoresponsive polyelectrolyte multilayer films were fabricated by layer-by-layer assembly of a tellurium-containing polymer, photosensitizer, and poly(styrenesulfonate). The resulting films were investigated by UV/vis spectroscopy, XPS, EPR, and fluorescence spectroscopy. Under visible light, the photosensitizer in the film is excited and transforms triplet oxygen into singlet oxygen in aqueous solution. Singlet oxygen oxidizes -Te- to high valence state (Te═O) on the polymer backbone. The generated (Te═O) group makes the micelles more hydrophilic and looser, thereby facilitating the controlled release of the loaded cargo of micelles. These results show that the film has the potential to be used for cargo loading and controlled release, thus may provide a new way to combine photodynamic therapy and chemotherapy. PMID:27301845

  2. Evaluation of the Efficacy of Combined Continuous Arterial Infusion and Systemic Chemotherapy for the Treatment of Advanced Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Purpose. To evaluate the effects of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in patients with advanced pancreatic carcinoma. Methods. CTAI was performed in 17 patients with stage IV pancreatic cancer with (n = 11) or without (n = 6) liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The inferior pancreatic artery (IPA) was embolized to achieve delivery of the pancreatic blood supply through only the celiac artery. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. Treatment effects were evaluated based on the primary tumor size, liver metastasis, and survival time and factors such as tumor size, tumor location, and stage of pancreatic carcinoma; the embolized arteries were analyzed with respect to treatment effects and prognosis. Results. A catheter was fixed in the gastroduodenal artery and splenic artery in 10 and 7 patients, respectively. Complete peripancreatic arterial occlusion was successful in 10 patients. CT showed a decrease in tumor size in 6 of 17 (35%) patients and a decrease in liver metastases in 6 of 11 (55%) patients. The survival time ranged from 4 to 18 months (mean ± SD, 8.8 ± 1.5 months). Complete embolization of arteries surrounding the pancreas was achieved in 10 patients; they manifested superior treatment effects and prognoses (p < 0.05). Conclusion. In patients with advanced pancreatic cancer, long-term CTAI with systemic chemotherapy appeared to be effective not only against the primary tumor but also against liver metastases. Patients with successfully occluded peripancreatic arteries tended to survive longer

    Full Text Available Objective: The aim of this study was to evaluate the therapeutic efficacy and toxicity of a combination of tegafur-gimeracil-oteracil potassium capsules (S-1 with oxaliplatin for treatment of advanced or recurrent colorectal cancer. Subjects and Methods: Between October 2009 and October 2011, 70 patients at our hospital with advanced or recurrent colorectal cancer were enrolled into our study and divided randomly into two groups: A treatment group (S-1 combined with oxaliplatin and a control group (Xeloda combined with oxaliplatin. All patients received 130 mg/m 2 oxaliplatin by intravenous infusion on day 1, every three weeks. Patients in the treatment group were treated with oral administration of 30-40 mg/m 2 S-1 twice daily for 14 days. Patients in the control group were treated with oral administration of 1000 mg/m 2 Xeloda twice daily for 14 days. The efficacy and toxicity of the combination therapy were evaluated after two cycles of treatment. Results: The response rates in the treatment and control groups were 54.3% and 42.9%, respectively. The disease control rates of the two groups were 80.0% and 74.3%, respectively. The 1-year and 2-year survival rates were 73.6% and 39.1% in the treatment group, respectively, compared to 73.8% and 37.8% in the control group. No statistical difference between the two groups for any of the parameters, including toxicity, was observed (P > 0.05. Conclusion: The efficacy of the S-1 and oxaliplatin combination regimen in advanced or recurrent colorectal cancer treatment is not inferior to the combination of Xeloda and oxaliplatin and does not result in additional toxicity. Therefore, S-1 could be used to substitute Xeloda in combined chemotherapy with oxaliplatin for the treatment of advanced or recurrent colorectal cancer.

    AIM: To investigate the poor prognosis of HCC with PVTT, we evaluated the efficacy by a new combination chemotherapy for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).METHODS: From 2002 to 2007, a total of 10 consecutive patients with Stage IVA HCC accompanied by PVTT were studied prospectively to examine the efficacy of treatment by intra-arterial infusion of a chemotherapeutic agents consisting of etoposide, carboplatin, epirubicin and pharmacokinetic modulating chemotherapy by 5-FU and enteric-coated tegafur/uracil.RESULTS: The mean course of chemotherapy was 14.4 (range, 9-21) mo. One patient showed complete response (CR) with disappearance of HCC and PVTT after treatment, and the two patients showed partialresponse (PR), response rate (CR + PR/All cases 30%).The median survival time after the therapy was 457.2 d. The one-year survival rate was 70%. Adverse reactions were tolerable.CONCLUSION: Although the prognosis of most patients with Stage IVA HCC by PVTT is poor, our combination chemotherapy may induces long-term survival and is an effective treatment and produced anti-tumor activity with tolerable adverse effects in patients for advanced Stage IVA HCC accompanied by PVTT.

  5. Prognostic value of hemoglobin concentrations in patients with advanced head and neck cancer treated with combined radio-chemotherapy and surgery

    International Nuclear Information System (INIS)

    Purpose: Hemoglobin levels are currently the focus of interest as prognostic factors in patients with head and neck cancer. Most published clinical trials have confirmed hemoglobin to process a significant influence on survival in patients treated with radiotherapy. In our study we have investigated the prognostic value of hemoglobin in a combined modality schedule. Patients and Methods: Forty-three patients with advanced head and neck tumors were treated with combined radiochemotherapy. The therapy comprised 2 courses of induction chemotherapy with ifosfamide (1,500 mg/m2, day 1 to 5) and cisplatin (60 mg/m2, day 5) followed by hyperfractionated accelerated radiotherapy with a total dose of only 30 Gy. Surgery involved tumor resection and neck dissection. Results: The 1-year overall survival rate and the 2-year survival rate were 79% and 56%, respectively. The 1- and 2-year recurrence-free survival rates were 68% and 49%, respectively. Prognostic factors with an impact on survival were seen in tumor size (T3 vs T4, p=0.0088), response to radio-chemotherapy at the primary site (no vital tumor rest vs vital tumor rest, p=0.045), response to lymph node radio-chemotherapy (no vital tumor cells vs vital tumor cells, p=0.013) and level of hemoglobin after radio-chemotherapy (Hb≥11.5 g/dl vs <11.5 g/dl, p=0.0084). Conclusion: In our study hemoglobin level after radio-chemotherapy was identified for the first time to be also a significant prognostic factor (univariate analysis) in head and neck cancer patients who underwent combined radio-chemotherapy. Besides chemotherapy plus low-dose irradiation achieved similar results in comparison with radical resection and high-dose radiotherapy at least for the first 2 years after therapy. Relapsing disease could be treated with 1 additional course of radiotherapy which is supposed to be well tolerated. (orig.)

    Full Text Available Abstract Background Activation of the epidermal growth factor receptor (EGFR triggers downstream signaling pathways that regulate many cellular processes involved in tumour survival and growth. Gefitinib ('Iressa' is an orally active tyrosine kinase inhibitor (TKI targeted to the ATP-binding domain of EGFR (HER1; erbB1. Methods In this study we have used a standardised ATP-based tumour chemosensitivity assay (ATP-TCA to measure the activity of gefitinib alone or in combination with different cytotoxic drugs (cisplatin, gemcitabine, oxaliplatin and treosulfan against a variety of solid tumours (n = 86, including breast, colorectal, oesophageal and ovarian cancer, carcinoma of unknown primary site, cutaneous and uveal melanoma, non-small cell lung cancer (NSCLC and sarcoma. The IC50 and IC90 were calculated for each single agent or combination. To allow comparison between samples the IndexSUM was calculated based on the percentage tumour growth inhibition (TGI at each test drug concentration (TDC. Gefitinib was tested at concentrations ranging from 0.0625–2 microM (TDC = 0.446 microg/ml. This study represents the first use of a TKI in the assay. Results There was heterogeneity in the degree of TGI observed when tumours were tested against single agent gefitinib. 7% (6/86 of tumours exhibited considerable inhibition, but most showed a more modest response resulting in a low TGI. The median IC50 value for single agent gefitinib in all tumours tested was 3.98 microM. Interestingly, gefitinib had both positive and negative effects when used in combination with different cytotoxics. In 59% (45/76 of tumours tested, the addition of gefitinib appeared to potentiate the effect of the cytotoxic agent or combination (of these, 11% (5/45 had a >50% decrease in their IndexSUM. In 38% of tumours (29/76, the TGI was decreased when the combination of gefitinib + cytotoxic was used in comparison to the cytotoxic alone. In the remaining 3% (2/76 there was no

    Prostate cancer (PC) is a heterogeneous disease, whose growth is driven by androgens and androgen receptors. Androgen deprivation therapy (ADT) is the standard treatment of hormone-naïve metastatic disease. The majority of patients are treated with medical castration with GnRH agonists or antagonists, which usually determines a profound PSA decline and a radiological and clinical benefit. However, essentially all patients experience progression to castration-resistant prostate cancer (CRPC), and overall prognosis remains disappointing. Early targeting of cells that survive hormonal therapy may potentially prevent the development of CRPC. Several trials have explored the use of combination therapy with ADT and chemotherapy, targeting both the androgen dependent and independent cells simultaneously. Docetaxel was administered in combination with ADT to men with hormone-naïve metastatic prostate cancer, in the attempt to improve the duration and quality of patient survival. Three large randomized trials (the GETUG-15, CHAARTED and more recently the STAMPEDE study) have assessed these endpoints, with partially conflicting results. Overall, the results from these trials seem to support the use of early docetaxel combined with ADT in selected hormone-naïve metastatic PC patients. Full publication of the results of all studies, with longer follow-up, and the results of other ongoing trials in this setting will hopefully further define the role and the indications of this therapeutic strategy.

  8. High-dose intravenous vitamin C combined with cytotoxic chemotherapy in patients with advanced cancer: a phase I-II clinical trial.

    Directory of Open Access Journals (Sweden)

    L John Hoffer

    Full Text Available Biological and some clinical evidence suggest that high-dose intravenous vitamin C (IVC could increase the effectiveness of cancer chemotherapy. IVC is widely used by integrative and complementary cancer therapists, but rigorous data are lacking as to its safety and which cancers and chemotherapy regimens would be the most promising to investigate in detail.We carried out a phase I-II safety, tolerability, pharmacokinetic and efficacy trial of IVC combined with chemotherapy in patients whose treating oncologist judged that standard-of-care or off-label chemotherapy offered less than a 33% likelihood of a meaningful response. We documented adverse events and toxicity associated with IVC infusions, determined pre- and post-chemotherapy vitamin C and oxalic acid pharmacokinetic profiles, and monitored objective clinical responses, mood and quality of life. Fourteen patients were enrolled. IVC was safe and generally well tolerated, although some patients experienced transient adverse events during or after IVC infusions. The pre- and post-chemotherapy pharmacokinetic profiles suggested that tissue uptake of vitamin C increases after chemotherapy, with no increase in urinary oxalic acid excretion. Three patients with different types of cancer experienced unexpected transient stable disease, increased energy and functional improvement.Despite IVC's biological and clinical plausibility, career cancer investigators currently ignore it while integrative cancer therapists use it widely but without reporting the kind of clinical data that is normally gathered in cancer drug development. The present study neither proves nor disproves IVC's value in cancer therapy, but it provides practical information, and indicates a feasible way to evaluate this plausible but unproven therapy in an academic environment that is currently uninterested in it. If carried out in sufficient numbers, simple studies like this one could identify specific clusters of cancer type

    Primary ovarian squamous cell carcinoma is uncommon, and the optimal treatment strategy for this disease has not yet been established. A 71-year-old woman diagnosed with FIGO stage IIb pure ovarian squamous cell carcinoma underwent cytoreductive surgery followed by combination chemotherapy with paclitaxel and carboplatin. After the second treatment course, a recurrent mass grew rapidly, and serum tumor maker levels increased. Monotherapy with weekly irinotecan was then instituted. This second-line chemotherapy was remarkably effective, and the patient subsequently underwent complete interval debulking surgery with a pathological complete response after the third treatment course. Weekly irinotecan is an effective choice for primary ovarian squamous cell carcinoma resistant to combination chemotherapy with paclitaxel and carboplatin. PMID:25511544

    Full Text Available A comparative study of cutaneous toxicities of two different commonly used combination chemotherapeutic regimens was conducted on 16 patients of non-Hodgkin′s lymphoma. The common drugs in the two regimens were cyclophosphamide, vincristine and prednisone. One of the regimens which was administered to 10 patients, included doxorubicin as an additional drug. This combination is preferred in high grade malignancy. However, the addition of doxorubicin resulted in enhanced severity and multiplicity of cutaneous manifestations. If it is possible to choose between two or more regimens for a given malignancy, the risk-benefit ratio can be weighed to choose the appropriate and least toxic drugs.

    Full Text Available The combination of chemotherapy and epidermal growth factor receptor (EGFR tyrosine kinase inhibitors (TKIs currently has become the hotspot issue in the treatment of non-small lung cancer (NSCLC. This systematic review was conducted to compare the efficacy and safety of the synchronous combination of these two treatments with EGFR TKIs or chemotherapy alone in advanced NSCLC.EMBASE, PubMed, the Central Registry of Controlled Trials in the Cochrane Library (CENTRAL, Chinese biomedical literature database (CNKI and meeting summaries were searched. The Phase II/III randomized controlled trials were selected by which patients with advanced NSCLC were randomized to receive a combination of EGFR TKIs and chemotherapy by synchronous mode vs. EGFR TKIs or chemotherapy alone.A total of six randomized controlled trials (RCTs including 4675 patients were enrolled in the systematic review. The meta-analysis demonstrated that the synchronous combination group of chemotherapy and EGFR TKIs did not reach satisfactory results; there was no significant difference in overall survival (OS, time to progression (TTP and objective response rate (ORR, compared with monotherapy (OS: HR = 1.05, 95%CI = 0.98-1.12; TTP: HR = 0.94, 95%CI = 0.89-1.00; ORR: RR = 1.07, 95%CI = 0.98-1.17, and no significant difference in OS and progression-free survival (PFS, compared with EGFR TKIs alone (OS: HR = 1.10, 95% CI = 0.83-1.46; PFS: HR = 0.86, 95% CI = 0.67-1.10. The patients who received synchronous combined therapy presented with increased incidences of grade 3/4 anemia (RR = 1.40, 95% CI = 1.10-1.79 and rash (RR = 7.43, 95% CI = 4.56-12.09, compared with chemotherapy, grade 3/4 anemia (RR = 6.71, 95% CI = 1.25-35.93 and fatigue (RR = 9.60, 95% CI = 2.28-40.86 compared with EGFR TKI monotherapy.The synchronous combination of chemotherapy and TKIs is not superior to chemotherapy or EGFR TKIs alone for the first-line treatment of NSCLC.

    2007-05-01

    Full Text Available Abstract Background Diagnosis of breast cancer during pregnancy was formerly considered an indication for abortion. The pendulum has since swung to the other extreme, with most reviews now rejecting termination while endorsing immediate anthracycline-based therapy for any pregnant patient beyond the first trimester. To assess the evidence for this radical change in thinking, a review of relevant studies in the fields of breast cancer chemotherapy, pregnancy, and drug safety was conducted. Discussion Accumulating evidence for the short-term safety of anthracycline-based chemotherapy during late-trimester pregnancy represents a clear advance over the traditional norm of therapeutic abortion. Nonetheless, the emerging orthodoxy favoring routine chemotherapy during gestation should continue to be questioned on several grounds: (1 the assumed difference in maternal survival accruing from chemotherapy administered earlier – i.e., during pregnancy, rather than after delivery – has not been quantified; (2 the added survival benefit of adjuvant cytotoxic therapy prescribed within the hormone-rich milieu of pregnancy remains presumptive, particularly for ER-positive disease; (3 the maternal survival benefit associated with modified adjuvant regimens (e.g., weekly schedules, omission of taxanes, etc. has not been proven equivalent to standard (e.g., post-delivery regimens; and (4 the long-term transplacental and transgenerational hazards of late-trimester chemotherapy are unknown. Summary Although an incrementally increased risk of cancer-specific mortality is impossible to exclude, mothers who place a high priority on the lifelong well-being of their progeny may be informed that deferring optimal chemotherapy until after delivery is still an option to consider, especially in ER-positive, node-negative and/or last-trimester disease.

    2001-01-01

    Objective: To assess the effect and mechanism of compound Xiansu capsule (仙酥胶囊, XSC) combined with chemotherapy in treating gastric carcinoma of mid-late stage. Methods: Sixty-one patients of the test group were treated by XSC combined with chemotherapy and 30 patients of the control group treated with chemotherapy alone. The effect of treatment and cell mediated immunity of patients were observed. Results: The effective rate of the test group and the control group was 32.8% and 13.3% respectively (P<0.05), the toxic reaction occurrence caused by chemotherapy was less in the former than that in the latter group (P<0.01). The CD8 level of patients in the test group decreased, and CD4/CD8 level was raised obviously, which suggested that XSC had immuno-regulating effect on T-cell. Conclusion: XSC could enhance the efficacy and reduce the toxic and side-effect of chemotherapy. To regulate the cell mediated immunity of patients is possibly its mechanism.

    Based on encouraging results reported in alternating radiotherapy and chemotherapy in inflammatory breast carcinoma, we have tried in this study to optimize locoregional treatment with a hyperfractionated accelerated radiotherapy schedule alternating with chemotherapy. From May 1991 to May 1995, 54 patients, previously untreated, with non-metastatic inflammatory breast cancer were entered in an alternating protocol consisting of eight courses of combined chemotherapy and two series of loco-regional hyperfractionated accelerated radiotherapy with a total dose of 66 Gy. Hyperfractionated accelerated radiotherapy was started after three courses of neo-adjuvant chemotherapy (Adriamycin, Vincristine, Cyclophosphamide, Methotrexate, 5-fluoro-uracil) administered every 21 days {+-}G.CSF. The first series delivered 45 Gy/three weeks to the breast, the axillary, sub-clavicular and internal mammary nodes, with two daily sessions of 1.5 Gy separated by an interval of eight hours, the second series consisted of a boost (21 Gy/14 fractions/10d) alternating with another regimen of anthracycline-based-chemotherapy (a total of five cycles every three weeks). Hormonal treatment was given to all patients. Of the 53 patients evaluated at the end of the treatment, 44(83%) had a complete clinical response, seven (13%) had a partial response (>50%) and two (4%) had tumoral progression. Of the 51 patients who were locally controlled, 18 (35%) presented a locoregional recurrence (LRR); eight(15 %) had to undergo a mastectomy. All the patients but two LRR developed metastases or died of local progressive disease and 26 (50%) developed metastases. With a median follow-up of 39 months (range: 4-74 months), survival rates at three and five years were respectively, 66 and 45% for overall survival and 45 and 36% for disease-free survival. Alternating a combination of chemotherapy and hyperfractionated accelerated radiotherapy is a well-tolerated regimen which provides acceptable local control

    Full Text Available Abstract Background Platinum-based chemotherapy has been a standard therapy for advanced non-small cell lung cancer (NSCLC, but it has high toxicity. In China, Shenqi Fuzheng, a newly developed injection concocted from Chinese medicinal herbs has been reported that may increase efficacy and reduce toxicity when combined with platinum-based chemotherapy, but little is known about it outside of China. The aim of this study was to systematically review the existing clinical evidence on Shenqi Fuzheng Injection(SFI combined with platinum-based chemotherapy for advanced NSCLC. Methods Pubmed, Cochrane Library, EMBASE, CNKI, and CBM search were organized for all documents published, in English and Chinese, until April 2010. The randomized controlled clinical trials were selected based on specific criteria, in which a SFI plus platinum-based chemotherapy treatment group was compared with a platinum-based chemotherapy control group for patients with advanced NSCLC. The quality of studies was assessed by modified Jadad's scale, and Revman 4.2 software was used for data syntheses and analyses. Results Twenty nine studies were included in this review based on our selection criteria. Of them, ten studies were of high quality and the rest were of low quality, according to the modified Jadad scale. The meta-analysis showed there was a statistically significant higher tumor response (RR, 1.19; 95% CI, 1.07 to 1.32; P = 0.001 and performance status ((RR, 1.57; 95% CI, 1.45 to 1.70; P P = 0.016. Conclusions SFI intervention appears to be useful to increase efficacy and reduce toxicity when combined with platinum-based chemotherapy for advanced NSCLC, although this result needs to be further verified by more high-quality trials.

  19. Combined preoperative neoadjuvant radiotherapy and chemotherapy for anal and rectal cancer

    International Nuclear Information System (INIS)

    Neoadjuvant therapy combining 5-fluorouracil, mitomycin C, and moderate-dose radiotherapy was given preoperatively to 29 patients with adenocarcinoma of the rectum, 3 patients with squamous cell cancer, and 1 patient with basaloid carcinoma of the anus. Significant downstaging, and even eradication, of these lesions was realized in a high percentage of cases. Population-based data for the period of 1979 to 1984 which encompasses the time of our study indicate the survival of those treated by the neoadjuvant therapy was superior to that of patients treated by surgery alone or by surgery followed by radiotherapy. In general, patients with the poorest clinical presentation had been referred for this therapy

    OBJECTIVE To investigate the relationship between the therapeutic modality and prognostic factors for the patients with T3N0~1M0 nasopharyngeal carcinoma.METHODS The clinical data from 127 cases of T3N0~1M0 nasopharyngeal carcinoma patients with initial treatment, during the period from January 4th, 2000 to November 12th, 2001, were retrospectively analyzed. The cases were divided into Group A with simple radiotherapy (90) and Group B with the radiation therapy combined with chemotherapy (37), based on various patients' conditions. In group B, inductive chemotherapywas conducted for 18 cases, inductive chemotherapy plus homochronous chemotherapy for 5 and homochronous chemotherapy for 14.RESULTS The 5-year overall survival (OS) in the groups A and B was 73.4% and 72.3% respectively (P>0.05); the cancer-correlated survival (CCS) in the 2 groups was 76.4% and 72.3% respectively (P>0.05); the disease-free survival (DFS) in group A and B was 65.5% and 71.7% respectively (P<0.05). A multiple analysis showed that the mode of radiation therapy plus chemotherapy was a favorable independent impact factor for DFS.CONCLUSION Chemotherapy plus radiotherapy can improve the DFS of patients with T3N0~1M0 nasopharyngeal carcinoma, but fails to prolong the survival time of the patients. The modality of chemotherapy plus radiotherapy is not the necessary choice in treatment of patients with T3N0~ 1M0 nasopharyngeal carcinoma.

  1. Prevention of lung metastases by irradiation alone or combined with chemotherapy in an animal model

    International Nuclear Information System (INIS)

    Clinical observations indicate that the results of elective radiotherapy are disappointing when the subclinical metastases supposedly contain a large number of tumor cells. Experimental data confirm this indication: a rapid decrease in the effectiveness of radiation treatment of experimental metastases was observed with increasing number of tumor cells in the lung. Apart from the increase in cell number also the development of hypoxia during growth of subclinical metastases might explain part of the decrease in the effectiveness of elective radiation treatment. Experiments with the hypoxic cell sensitizer misonidazole in transplantable tumors in rodents indicate that this latter possibility might be relevant too for the clinical situation. Improvement of the results of an elective treatment might either be obtained by a reduction of the cell number to be treated with radiation, by prior treatment with a cytostatic drug or be dealing with the problem of hypoxia. Therefore in the present study the authors investigate the effectiveness of thorax irradiation combined with the treatment with cytostatic drugs (Actinomycin-D or 5-Fluorouracil) or the hypoxic cell sensitizer misonidazole in a mouse model with artificial lung metastases. The artificial lung metastases were obtained by intravenous injection of tumor cells in the tail vein of mice. The influence of thorax irradiation on the development of lung metastases was evaluated not only by recording the number of mice dying from lung metastases as parameter but also registered the pattern of lung metastases found at autopsy of animals which died from their disease. The response of lung tissue following combined therapy was also investigated

  2. Prospective multicenter study of combined treatment with chemotherapy and radiotherapy in breast cancer women with the rare clinical scenario of ipsilateral supraclavicular node recurrence without distant metastases

    International Nuclear Information System (INIS)

    Purpose: To evaluate the role of chemotherapy combined with curative radiotherapy in breast cancer patients who presented with recurrent ipsilateral supraclavicular lymph node metastases (ISLM) without 'nonregional disease,' we designed an observational study performed prospectively. Patients and Methods: Forty-four consecutive patients with ISLM from breast cancer as part of recurrent regional disease without distant metastases were included in this study. All patients received chemotherapy with doxorubicin-based schema or paclitaxel for six courses and curative radiotherapy (60 Gy/30 fractions of 2 Gy/5 days a week). An 'involved field' radiation was delivered during the interval between the third and fourth chemotherapy course; hormonal therapy was given based on receptor status. Results: The rate of overall clinical response after chemotherapy and radiotherapy was 94.9%. Median time to progression and overall survival were 28 and 40 months, respectively; the 5-year actuarial overall survival and disease-free survival rates were 35% (95% confidence interval, 19-51) and 20% (95% confidence interval, 6-34), respectively. Conclusion: A curative course of intravenous chemotherapy and radical irradiation is feasible in patients with ISLM. All patients presenting recurrence in supraclavicular nodes should be treated with definitive locoregional treatments and systemic therapy because the outcomes are better than might be historically assumed

    Biomarkers predicting resistance to particular chemotherapy regimens could play a key role in optimally individualized treatment concepts. PTK7 (protein tyrosine kinase 7) belongs to the receptor tyrosine kinase family involved in several physiological, but also malignant, cell behaviors. Recent studies in acute myeloid leukemia have associated PTK7 expression with resistance to anthracycline therapy. PTK7 mRNA expression in primary tumor tissue (PTT) and corresponding lymph node tissue (LNT) were retrospectively measured in 117 patients with early breast cancer; PTK7 expression was available in 103 PTT and 108 LNT samples. Median age was 60 years (range, 27-87 years). At a median follow-up of 28.5 months, 6 deaths and 16 recurrences had occurred. PTK7 expression correlations with clinicopathological features were computed and PTK7 expression effects on patient outcome were analyzed in three cohorts defined by adjuvant treatment: anthracycline-based treatment, other chemotherapy regimens (including taxane or other substances), or no chemotherapy. Association of PTK7 expression with clinicopathological features was seen only for age in PTT and nodal stage in LNT. High LN PTK7 was associated with poorer disease-free survival (DFS) in the total population (3-year DFS: low [81.7%] versus high [70.4%]; P=0.016) and in patients without adjuvant chemotherapy (3-year DFS: low [91.7%] versus high [22.3%]; P<0.001), but not in patients receiving adjuvant chemotherapy (P=0.552). DFS stratified by PTK7 expression was compared in treatment cohorts: In patients with low LN PTK7 expression, neither chemotherapy cohort showed significantly better survival than the no-chemotherapy cohort. In patients with high LN PTK7 expression, those receiving chemotherapy, including substances other than anthracyclines, but not those receiving only anthracycline-based chemotherapy, showed significantly better DFS than those receiving no chemotherapy (P=0.001). Our results support earlier

  4. Analysis of the impact of platinum-based combination chemotherapy in small cell cervical carcinoma: a multicenter retrospective study in Chinese patients

    International Nuclear Information System (INIS)

    Small cell cervical carcinoma (SCCC) is a rare, aggressive tumor with a poor prognosis. However, information in relation to its treatment is scarce due to the limited numbers of patients. The aim of this study was to establish whether platinum-based combination chemotherapy may by beneficial in this patient population. We carried out a multicenter, retrospective study comprising of 72 Chinese patients with SCCC. The patients were treated between 1995 and 2010 at Sun Yat-sen Memorial Hospital or the Cancer Center of Sun Yat-Sen University, and at the First Affiliated Hospital of Shantou University Medical College, China. Of the 72 patients, 46/72 (63.9%) had Federation of Gynecology and Obstetrics (FIGO) stage Ia–Ib2 and 26/72 (36.1%) had stage IIa–IV disease. Surgery was performed in 63/72 (87.5%) patients, 61/72 (84.7%) patients received chemoradiotherapy and 35/72 (48.6%) received radiotherapy. The 3-year overall survival (OS) and disease-free survival (DFS) rates were as follows: Ia (100%, 100%); Ib1 (62%, 57%); Ib2 (53%, 48%); IIa (36%, 23%); IIb (29%, 21%); IIIb (50%, 50%); and IV (0%, 0%), respectively. The estimated 3-year OS and DFS rates in patients who received platinum-based combination chemotherapy (etoposide + cisplatin [EP], or paclitaxel + cisplatin [TP]) as part of their adjuvant treatment were 64.8% and 63.0%, respectively, compared to 25.2% and 22.0% in those who did not (P = 0.0003; P = 0.0003). Univariate analysis showed that platinum-based combination chemotherapy was associated with improved survival compared to other chemotherapy techniques or no chemotherapy (OS: HR = 0.227; 95% CI, 0.099–0.524; P = 0.001; DFS: HR = 0.210; 95% CI, 0.087–0.506; P = 0.001). Multivariate analysis identified FIGO stage, lymphatic metastasis and platinum-based combination chemotherapy as independent prognostic factors for improved survival in patients with SCCC. Platinum-based combination chemotherapy (with EP or TP) can improve the 3-year survival

    Full Text Available Therapy-related leukemia (TRL has been reported to occur after treatment with alkylating agents and/or topoisomerase II inhibitors. Oxaliplatin (OXP is used as a key drug for the treatment of colorectal cancer (CRC. Cisplatin and carboplatin have been linked with TRL, but the involvement of OXP is questionable. A 74-year-old male was diagnosed with peritoneal metastasis from CRC in July 2011. The patient received nine cycles of 5-fluorouracil (5-FU, leucovorin (LV, and OXP (mFOLFOX-6 regimen and three cycles of 5-FU and LV only, resulting in a clinical complete response. However, recurrence of CRC was detected by CT within 3 months after the last course of chemotherapy. In April 2013, laboratory tests showed pancytopenia and 15% blast cells. A bone marrow examination revealed multilineage dysplasia and 20.4% myeloblasts. Cytogenetic analysis indicated a complex karyotype that included chromosome 5 and 7 abnormalities. The patient was diagnosed with TRL and treated with a combination of azacitidine (AZA and cetuximab (Cmab for both cancers. AZA might be useful in TRL when a patient needs to be treated simultaneously for more than one primary cancer because of its low toxicity. Moreover, Cmab is an effective therapeutic tool in TRL patients with metastatic CRC with the wild-type K-ras gene.

    The objective of the present study was to estimate the possibilities and prospects for the use of regional intra-arterial chemotherapy in the combined treatment of locally advanced laryngeal cancer. The results of the chemoradiotherapeutic treatment of 26 patients presenting with locally advanced laryngeal cancer were analysed. The chemical agents were selectively administered intra-arterially three times from the right-hand femoral access by the standard procedure at a total focal dose (TFD) of 26 and 50 gram prior to the onset of and during of radiotherapy. The very first administration of the chemical agent resulted in the 30% decrease the tumour size. It further decreased by 70% on the average after the TFD of 50 gram was achieved. It made possible the continuation of gamma-therapy up to the total therapeutic dose. As a result, complete regression of the tumour was documented. The dynamic endoscopic control study and CT of the larynx revealed recurrent laryngeal cancer in 1 of the 26 patients (3.8%). The remaining patients did not develop metastases during the 18 month follow-up period. It is concluded that the results of the present study confirm high (96.2%) effectiveness of the method employed in this study which allows it to be recommended for the organ-preserving treatment of locally advanced laryngeal cancer.

    International Nuclear Information System (INIS)

    Objective: To discuss the clinical effects and the safety of intravenous drip transfusion of recombinant human edentate's combined with arterial infusion chemotherapy for the treatment of advanced carcinomas. Methods: Forty-one patients with advanced carcinomas were enrolled in this study. The patients were divided into study group and control group. All patients underwent relevant infusion chemotherapy via the tumor-feeding artery. At the same day when the arterial infusion chemotherapy was completed, patients in study group stated to receive intravenous drip transfusion of recombinant human endostatin, which lasted for 14 days and, then, broke for 7 days (regarded as one therapeutic cycle). No additional treatment was given to the patients in control group. After two therapeutic cycles, the clinical effect was evaluated with RE-CIST criteria and the living quality was assessed with Karnofsky scoring. The adverse effect was compared between two groups. Results: The control rate of disease and the Karnofsky score were significantly higher in study group than thase in control group (P 0.05). Conclusion: For the treatment of advanced carcinomas, intravenous drip transfusion of recombinant human endostatin combined with arterial infusion chemotherapy can markedly improve patient's living quality and disease control rate, besides, this therapy carries few adverse effects. Therefore, it is well worth making the effort to popularize this technique in clinical practice.(authors)

    Objective The aim of the present study was to investigate the ef ect of dendritic cel (DC)/cytokine-in-duced kil er cel (CIK) immunobiological cancer therapy in patients with triple-negative breast cancer (TNBC) who underwent adjuvant chemotherapy. Methods From January 2010 to October 2013, 120 patients with postoperative TNBC were recruited and included in the study. Patients were enrol ed in one of two groups according to whether they accepted DC/CIK immunobiological cancer therapy during adjuvant chemotherapy; the patients in the DC/CIK group underwent adjuvant chemotherapy combined with DC/CIK immunobiological cancer therapy, and the control group underwent adjuvant chemotherapy alone. When six cycles of adjuvant chemotherapy and six cycles of DC/CIK immunobiological cancer therapy had been completed, dif erences between the two groups with regard to quality of life (QoL), immunological indicators (CD3, CD4, CD8, and NK cel levels), disease-free survival (DFS), and side ef ects of chemotherapy and DC/CIK treatment were evaluated. Results In the DC/CIK group, the proportion of NK cel s and CD3+ and CD4+ T-cel subgroups significantly increased, and the proportion of CD8+ cel s decreased when they were compared before and after DC/CIK therapy (P Conclusion The DC/CIK treatment had potential benefits for patients with TNBC compared with the con-trol group, and was not associated with any obvious side ef ects. Therefore, DC/CIK therapy is a safe and ef ective method for the treatment of TNBC.

    For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cel tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrol ed in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P=0.042), and the 3-year overal survival rates were 90.5%and 100%, respectively (P=0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cel tumors.

    BCL-2 Associated athanogene 1 (BAG-1) and Xeroderma pigmentosum group D (XPD) are involved in the nucleotide excision repair pathway and DNA repair. We aimed to investigate whether polymorphisms in BAG-1 and XPD have effects on chemotherapy sensitivity and survival in patients with advanced non-small-cell lung cancer (NSCLC) treated with vinorelbine combined cisplatin (NP) regimen. A total of 142 patients with diagnosed advanced NSCLC were recruited in the current study. NP regimen was applied for all eligible patients. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for BAG-1 (codon 324) and XPD (codons 312 and 751) genotyping. The treatment response was evaluated according to the RECIST guidelines. Progression-free survival (PFS) and overall survival (OS) were record as median and end point, respectively. As for BAG-1 codon 324, the chemotherapy sensitivity in NSCLC patients with CT genotype was 0.383 times of those with CC genotype (P < 0.05). With respect to XPD codon 751, the chemotherapy sensitivity in NSCLC patients with Lys/Gln genotype was 0.400 times of those with Lys/Lys genotype (P < 0.05). In addition, NSCLC patients carrying combined C/C genotype at codon 324 in BAG-1, Asp/Asp of XPD codon 312, and Lys/Lys of XPD codon 751 produced a higher efficacy of NP chemotherapy compared to those carrying mutation genotypes (all P < 0.05). Further, there were significant differences in PFS between patients with combined C/C genotype of BAG-1 codon 324, Lys/Lys genotype of XPD codon 751, and Asp/Asp genotype of XPD codon 312 and patients carrying BAG-1 codon 324 C/T genotype, XPD codon751 Lys/Gln genotype, and XPD codon312 Asp/Asn genotype (P < 0.05). Multivariate Cox regression analysis indicated that the combined wild-type of codon 324 XPD, codon 751 XPD, and codon 312 BAG-1 is the protective factor for OS and PFS, and clinical stages is the risk factor for OS and PFS. In conclusion, our research

  14. Treatment of non-Hodgkin's lymphoma of the nasal cavity and paranasal sinuses with radiation alone or in combination with chemotherapy or surgery

    International Nuclear Information System (INIS)

    Purpose: To evaluate the outcome and patterns of failure in patients with Non-Hodgkin's Lymphoma of the nasal cavity and paranasal sinuses treated either by radiation alone or combined radiation and surgery or radiation and chemotherapy. Materials and Methods: Forty-Four patients with sinonasal lymphoma (Ann Arbor Stage IE-IIE) were treated by radiation alone or in combination with surgery and/or chemotherapy at our institution. Thirty-three patients were stage I (75%), and nine (20%) were stage II. Two patients were not able to be staged. Thirty-five patients were treated with radiation therapy alone, 4 patients received combination chemotherapy and radiation, and 5 patients received postoperative treatment with radiation. Results: The actuarial survival for the whole group at five years was seventy-three percent. The corresponding results for Stage I and Stage II were seventy percent and one hundred percent. The 5-year actuarial disease-specific survival was seventy-two percent for Stage I and one hundred percent for Stage II. The local control at 5 years was ninety-five percent for Stage I and one hundred percent for Stage II. Distant failure for the entire group occurred in (12(44)) (27%) patients. For patients treated with radiation alone, local failure occurred in (3(35)) (9%) patients while distant failure occurred in (9(35)) (28%) patients. Of those receiving combination chemotherapy and radiotherapy, (0(4)) failed locally and (1(4)) failed distantly. For those patients treated with surgery and radiation (0(5)) failed locally and (2(5)) failed distantly. Both local and distant failure occurred in (13(44)) patients for the entire group with (10(35)) for radiation alone and (1(4)) for chemotherapy combined with radiation and (2(5)) for surgery and radiation. Conclusion: Non-Hodgkin's Lymphoma involving the sinonasal regions of the Head and Neck is a rare tumor. Local control of this disease by radiation therapy alone is excellent. However distant failure

    For approximately a decade, chemotherapy has been shown to prolong life in patients with metastatic castration-resistant prostate cancer (mCRPC). Since that time, however, only two agents have proven to prolong life (docetaxel and cabazitaxel). However, in the last year, the addition of chemotherapy to primary hormonal therapy became a standard of care for high-volume castration-sensitive metastatic disease. Here I will review current prostate cancer chemotherapies, mechanisms of resistance to those therapies, and ongoing clinical studies of chemotherapy combinations and novel chemotherapeutics.

    Full Text Available Background. Huachansu, the sterilized water extract of Bufo bufo gargarizans toad skin, is used in China to alleviate the side-effects and enhance the therapeutic effect of chemotherapy in advanced non-small-cell lung cancer (NSCLC. We conducted a meta-analysis to assess Huachansu’s efficacy. Methods. We extensively searched electronic databases (CENTRAL, EMBASE, MEDLINE, CBM, Cochrane Library, CNKI, CEBM, WFDP, CSCD, CSTD, and IPA for randomized controlled trials containing Huachansu plus chemotherapy as the test group and chemotherapy as the control group. Seventeen trials were selected based on the selection criteria. The pooled relative ratio (RR of indicators with 95% confidence interval (95% CI was calculated for efficacy evaluation. Results. The meta-analysis demonstrated a statistically significant improvement in objective tumor response, one-year survival, Karnofsky performance status, pain relief, and alleviation of severe side-effects (nausea and vomiting, leukocytopenia in the test group as compared to the control group, but no significant difference in thrombocytopenia. Conclusions. This study demonstrated the efficacy of Huachansu combined with chemotherapy in the treatment of advanced NSCLC. However, limitations exist and high-quality trials are needed for further verification.

  2. Time-dependent changes in 18F-FDG activity in the thymus and bone marrow following combination chemotherapy in paediatric patients with lymphoma

    International Nuclear Information System (INIS)

    To investigate the time-dependent changes in 18F-FDG uptake by the thymus and marrow following combination chemotherapy for lymphoma in a paediatric study population. Included in the study were 27 paediatric patients who were in complete metabolic remission after chemotherapy and who underwent off-therapy follow-up with serial whole-body PET-CT scans. A total of 142 PET-CT scans were recorded. 18F-FDG uptake by the thymus and marrow was assessed both visually and semiquantitatively. Visual uptake was scored on the three-dimensional maximum intensity projection of the whole-body PET image according to a three-point scale. For the semiquantitative assessment, standard uptake values were measured. To find a pattern in the 18F-FDG uptake by the thymus and marrow a moving average technique was applied. Our time series analysis indicated that the marrow activity was highest at cessation of chemotherapy and declined thereafter. During an off-chemotherapy period of on average 6 months, marrow activity decreased quickly. From 6 months onward, the activity declined more slowly. The posttherapy changes in 18F-FDG uptake by the thymus were quite different from the changes in uptake by the marrow. The lowest thymic FDG uptake was found at cessation of chemotherapy. Thereafter, thymic activity steadily increased, reached a peak on average 10 months after therapy, and then slowly decreased. Knowledge of the time-dependent changes in metabolic activity in the thymus and marrow is important to avoid misinterpretation of increased 18F-FDG uptake as disease in the off-therapy setting.

  3. Locoregional Recurrence of Breast Cancer in Patients Treated With Breast Conservation Surgery and Radiotherapy Following Neoadjuvant Chemotherapy

    International Nuclear Information System (INIS)

    Purpose: Breast conservation surgery (BCS) and radiotherapy (RT) following neoadjuvant chemotherapy (NCT) have been linked with high locoregional recurrence (LRR) rates and ipsilateral breast tumor recurrence (IBTR) rates. The purpose of this study was to analyze clinical outcomes in patients who exhibited LRR and IBTR after being treated by BCS and RT following NCT. Methods and Materials: In total, 251 breast cancer patients treated with BCS and RT following NCT between 2001 and 2006 were included. All patients had been shown to be clinically node-positive. Clinical stage at diagnosis (2003 AJCC) was II in 68% of patients and III in 32% of patients. Of those, 50%, 35%, and 15% of patients received anthracycline-based, taxane-based, and combined anthracycline-taxane NCT, respectively. All patients received RT. Results: During follow-up (median, 55 months), 26 (10%) patients had LRR, 19 of these patients had IBTR. Five-year actuarial rates of IBTR-free and LRR-free survival were 91% and 89%, respectively. In multivariate analyses, lack of hormone suppression therapy was found to increase both LRR and IBTR rates. Hazard ratios were 7.99 (p < 0.0001) and 4.22 (p = 0.004), respectively. Additionally, pathology stage N2 to N3 increased LRR rate (hazard ratio, 4.22; p = 0.004), and clinical AJCC stage III IBTR rate (hazard ratio, 9.05; p = 0.034). Achievement of pathological complete response and presence of multifocal tumors did not affect LRR or IBTR. Conclusions: In patients with locally advanced disease, who were clinically node-positive at presentation, BCS after NCT resulted in acceptably low rates of IBTR and LRR. Mastectomy should be considered as an option in patients who present with clinical stage III tumors or who are not treated with adjuvant hormone suppression therapy, because they exhibit high IBTR rates after NCT and BCS.

  4. therapeutic effect of three-dimensional conformal involved-field radiotherapy combined with chemotherapy on limited disease stage small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To analyze the therapeutic effect of three-dimensional conformal involved-field radiotherapy (3D-CRT) combined with chemotherapy on limited disease stage small cell lung cancer (LD-SCLC). Methods: The clinical data of 85 patients of LD-SCLC treated with 3D-CRT at the dose of 2 Gy/fraction, 5 fractions per week for 5-7 weeks, with the median dose of 50 Gy (46-66 Gy), combined with 4-8 cycles chemotherapy, 64 males and 21 females, aged 29-76, were collected and analyzed. Results: The complete remission rate, partial remission rate, stability rate, and total effective rate were 36.5%, 52.9%, 10.6%, and 89.4%, respectively. The median survival time was 18 months, with the 1-, 2-, and 3-year overall survival rates of 65.9%, 33.8%, and 15.9%, respectively. The local recurrence rate, distant metastasis rate, and local recurrence + distant metastasis rate were 15.2% (9/85), 49.2% (29/85), and 35.6% (21/85), respectively. Body weight,response to therapy, cycles for chemotherapy, and concurrent chemo-radiotherapy were all independent prognostic factors for LD-SCLC. Cox multivariable regression was used to analyze the prognostic factors. Conclusions: Involved-field radiotherapy is effective for LD-SCLC. Distance metastasis is the main cause of treatment failure.

    A 25-year-old man was admitted to our hospital complaining of right scrotal pain and upper abdominal pain. A computed tomographic scan indicated a right scrotal mass, a huge liver mass, and multiple lung masses, although there was no enlarged retroperitoneal lymph node swelling. Laboratory tests showed severe liver and kidney dysfunction and high levels of serum α-fetoprotein (11,997 ng/ml). Although needle biopsies of the testicular and liver masses were performed, the tissues were insufficient for a pathological diagnosis. As liver and kidney function worsened, we started chemotherapy with bleomycin, etoposide, and cisplatin (BEP chemotherapy), which was modified because of the liver and renal dysfunction. We also used continuous hemodiafiltration and rasburicase to prevent tumor lysis syndrome. After induction of chemotherapy, the liver and kidney dysfunction improved immediately and the high orchiectomy was performed on day 8 after chemotherapy. The pathological diagnosis was a yolk sac tumor. He underwent four courses of the BEP regimen and five courses of the TIN regimen (paclitaxel, ifosphamide, and nedaplatin), followed by the resection of liver metastases. There was no evidence of viable cells in the resected liver and no recurrence was evident at 1 year postoperatively. PMID:26736135

  6. Intra-arterial infusion of radiosensitizer (BUdR) combined with hypofractionated irradiation and chemotherapy for primary treatment of osteogenic sarcoma

    International Nuclear Information System (INIS)

    Combined modality treatment was given in nine patients of osteogenic sarcoma wherein the tumor was unresectable because of location or amputation was refused. This alternative to massive surgery comprised hypofractionated irradiation, intra-arterial infusion of the radiosensitizer 5'-bromodeoxyuridine (BUdR) and adjuvant systemic chemotherapy. Local control was achieved in seven of the nine patients. Four survived, all without evidence of disease at 6, 7.1, 8.8, and 10.5 years after completion of irradiation. Pulmonary metastases developed in six patients - of whom one survives, following high-dose pulmonary irradiation and additional chemotherapy. Significant soft-tissue injury occurred in five patients. On the basis of our experience, the authors believe that new approaches using modifications of external beam irradiation with different fractionation schedules or better radiosensitizing compounds may hold promise for patients with non-resectable osteosarcoma

    Objective: The aim of the study was to evaluate the safety and therapeutic effects of autologous dendritic cells co-cultured with cytokine-induced killer cells (DC-CIK) combined with chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. Methods: Fifty patients with advanced NSCLC (stages III to IV), who had received therapies in our Center (Department of Biotherapy, Affiliated to Cancer Hospital of Shanxi Medical University, Taiyuan, China) from August 2008 to January 2010, were treated by DC-CIK + chemotherapy as the combined treatment group; fifty advanced NSCLC patients treated with chemotherapy at the same time served as controls. The immunologic function, short-term therapeutic effects, the 1-year survival rate, the life quality, the chemotherapy side effects were compared between the two groups, the safety and therapeutic effects of DC-CIK cells therapy were observed too. Results: There was no obvious change of subsets of T cells in peripheral blood before and after therapy in DC-CIK + chemotherapy group, and IFN-γ was improved after therapy in this group (P < 0.05); in chemotherapy alone group, the ratios of CD3+CD4+, CD3+CD8+, CD3-CD56+ cells and the secretion of IL-2, TNF-α decreased significantly after therapy (P < 0.05); the ratios of CD3+CD8+, CD3+CD56+ were improved after cell culture (P < 0.05). The disease control rate (DCR) of DC-CIK + chemotherapy group was higher than that in the chemotherapy alone group (78.0% vs 56.0%, P < 0.05); the 1-year survival rates of DC-CIK + chemotherapy group and chemotherapy alone group were 50% and 44% respectively, had no significant difference. Compared with chemotherapy alone group, the occurrence of chemotherapy side effects (including bone marrow suppression, nausea and vomiting, peripheral nerve toxicity) was less in the DC-CIK + chemotherapy group (P < 0.05). The physical and appetite were better in DC-CIK + chemotherapy group after therapy. Conclusion: To compare with simple chemotherapy, DC

    The aim of this study was to evaluate the efficacy and safety of the combination of docetaxel (TXT) plus tamoxifen (TAM) in advanced non-small-cell lung cancer (NSCLC) patients who had received platinum-based first-line chemotherapy. A total of 120 advanced NSCLC patients pretreated with platinum-based chemotherapy were randomized into two treatment groups (the TXT and TXT+TAM groups) in a 1 : 1 ratio. Reversal of P-glycoprotein (P-gp) expression, tumor response, progression-free survival, overall survival, and safety were evaluated on an intention-to-treat basis. The median number of cycles of allocated chemotherapy was four in each treatment group (range: 2-6 cycles). The overall response rate and disease control rate in the TXT+TAM group were significantly higher than those in the TXT group (36.7 vs. 15.0% for overall response rate, P=0.007; 85.0 vs. 68.3% for disease control rate, P=0.031). The combination of TXT and TAM could effectively reverse P-gp expression in tumor tissues and provide a significant survival benefit for advanced NSCLC patients compared with TXT alone (11.6 vs. 9.1 months, P=0.030). In addition, in the TXT+TAM group, patients achieving P-gp reversal had a significantly greater median progression-free survival and overall survival than nonreversal patients. Furthermore, the combined therapy showed a safety profile comparable to that of TXT. The combination of TXT and TAM may be an effective and safe treatment option for advanced NSCLC patients who have already developed P-gp-mediated multidrug resistance. PMID:26882453

    Anthracyclines are the mainstay of treatment of a variety of haematological malignancies and solid tumours. Unfortunately, the clinical use of these drugs is limited by cumulative, dose-related cardiotoxicity which may ultimately lead to a severe and irreversible form of cardiomyopathy. Thus, there is an increasing need for close cooperation among cardiologists, oncologists and haemato-oncologists. As anthracyclines save lives, the logical goal of this cooperation, besides preventing or mitigating cardiotoxicity, is to promote an acceptable balance between the potential cardiac side effects and the vital benefit of anticancer treatment. This manuscript, which is specifically addressed to the cardiologist who has not accumulated much experience in the field of cancer therapy, focuses on several topics, that is old and new mechanisms of cardiac toxicity, late cardiac toxicity, the importance of overall risk assessment, the key role of a cardiology consult before starting cancer therapy, and the pros and cons of primary and secondary prevention programmes.

    Combination therapy has been commonly used in chemotherapy, taking advantage of different effects of different chemotherapeutic agents. The treatment effects are often synergistic. The same approach has been investigated in laser phototherapy. Specifically, different combinations of laser photothermal interaction, laser photochemical interaction, immunotherapy and chemotherapy have been used in the treatment of tumors. These novel approaches showed promise in cancer treatment, particularly against metastatic tumors. The recent development in this area is discussed in this paper. Furthermore, a specific combination of photodynamic therapy (PDT) with a novel immunoadjuvant, glycated chitosan (GC), has shown to be effective in the treatment mammary tumors and lung tumors in mice. In the treatment of EMT6 tumor-bearing mice, the Photofrin-based PDT and GC has significantly increased the survival rates from 37.5% with PDT alone to 62.5% when a 0.1-ml 0.5% GC was peritumoral injected immediately after PDT treatment. The survival rate was further increased to 75.0% when GC of higher concentration was used. In comparison, the individual components of the PDT-GC treatment showed either no effect or very limited effects. In the treatment of a poorly immunogenic tumor model, Line 1 lung tumors in mice, the combination of PDT and GC resulted in a 37.5% survival rate, while no survival mice were observed with PDT alone.

    The aim of this prospective clinical trial was to investigate the efficacy and toxicity of a short-term, maintenance-free chemotherapy protocol in feline lymphoma. Twenty-six cats with confirmed diagnosis of high-/intermediate-grade lymphoma were treated with a 12-week protocol consisting of cyclic administration of l-asparaginase, vincristine, cyclophosphamide, doxorubicin and prednisolone. Complete (CR) and partial remission (PR) rates were 46 and 27%, respectively. Median duration of first CR was 394 days compared with a median PR duration of 41 days. No factor was identified to significantly influence the likelihood to reach CR. Overall survival amounted to 78 days (range: 9-2230 days). Median survival in CR cats was 454 days and in PR cats was 82 days. Toxicosis was mainly low grade with anorexia seen most frequently. In cats achieving CR, maintenance-free chemotherapy may be sufficient to attain long-term remission and survival. Factors aiding in prognosticating the likelihood for CR, strategies enhancing response and targeting chemotherapy-induced anorexia need to be identified in future. PMID:24548273

  20. Possibility of conservative local treatment after combined chemotherapy and preoperative irradiation for locally advanced noninflammatory breast cancer

    International Nuclear Information System (INIS)

    Purpose: The aims of this prospective study were to evaluate the outcome and the possibility of breast conservation therapy for patients with locally advanced noninflammatory breast cancer after primary chemotherapy followed by external preoperative irradiation. Methods and Materials: Between April 1982 and June 1990, 97 patients with locally advanced nonmetastatic and noninflammatory breast cancer were treated. The median follow-up was 93 months from the beginning of treatment. The induction treatment consisted of four courses of chemotherapy (doxorubicin, vincristine, cyclophosphamide, 5-fluorouracil) followed by preoperative irradiation (45 Gy to the breast and nodal areas). A fifth course of chemotherapy was given after radiation therapy. Three different loco-regional approaches were proposed, depending on the tumoral response. In 37 patients (38%) with residual tumor larger than 3 cm in diameter or located behind the nipple or with bifocal tumors, mastectomy and axillary dissection were performed. Sixty other patients (62%) benefited from conservative treatment: 33 patients (34%) achieved complete remission and no surgery was done but additional radiation boost was given to the initial tumor bed; 27 patients (28%) who had a residual mass less than or equal to 3 cm in diameter were treated by wide excision and axillary dissection followed by a boost to the excision site. After completion of local therapy, all patients received a sixth course of chemotherapy. A maintenance adjuvant chemotherapy regimen without anthracycline was prescribed (12 monthly cycles). Results: The 5-year actuarial loco-regional relapse rate was 16% after radiotherapy alone, 16% following wide excision and radiotherapy, and 5.4% following mastectomy. The 5-year loco-regional relapse rate was significantly higher after conservative local treatment (wide excision and radiotherapy, and radiotherapy alone) than after mastectomy (p = 0.04). After conservative local treatment, the 5-year breast

    The aim of the study was to evaluate the efficacy of a regimen consisting of rituximab and a platinum-containing chemotherapy with either Ifosfamide, Carboplatin and Etoposide (ICE) or Cisplatin, high-dose Ara-C and Dexamethasone (DHAP) in patients with relapsed or primary refractory diffuse large B-cell lymphoma. Ten patients with relapsed or primary refractory diffuse large B-cell lymphoma were treated from June 2000 until May 2001 with a platinum-containing chemotherapy regimen according to the ICE- or DHAP-protocol in combination with rituximab at the University of Muenster. Two cycles of ICE or DHAP and rituximab were given. In case of at least a minor response after 2 cycles, 2 additional cycles of the same combination were applied. Response rate, remission duration and duration of survival were evaluated. All 10 patients could be analysed with respect to these endpoints. No treatment related mortality was observed. The response rate (CR/PR) was 60% (10/50%). Twenty percent of the patients had progressive disease. The median duration of remission and survival was 3 and 3.5 months, respectively (range: 1-6 and 1-7 months, respectively), the survival rate was 10%. Eight of 10 patients died because of their underlying disease with short remission duration, 1 patient died of complications of allogeneic transplantation in CR. In conclusion, the combination of platinum-containing chemotherapy (ICE or DHAP) with rituximab demonstrates significant activity in intensively pretreated patients with relapsed or primary refractory diffuse large B-cell lymphoma. Considering the short duration of remission and survival, respectively, other experimental therapeutic approaches (e.g. allogeneic stem cell transplantation, radioimmunotherapy) should be pursued following this treatment in order to induce long-term remission.

  5. Treatment of advanced stage ovarian carcinoma with a combination of chemotherapy, radiotherapy, and radiosensitizer: report of a pilot study from the National Cancer Institute

    International Nuclear Information System (INIS)

    Twenty-eight patients with Stage III or IV ovarian carcinoma were treated with combined chemotherapy-radiotherapy employing a unique protocol. Four cycles of cyclophosphamide and hexamethylmelamine alternated with four cycles of concurrent cisplatin, whole abdominal radiotherapy, and intraperitoneal misonidazole. The entire treatment program lasted six months. Clinical complete responses were seen in 50% of the patients with an overall response rate of 61%. Pathologic complete response (PCR) confirmed at second look surgery occurred in 18% of the group (5 patients). Median survival of the entire group was 15.2 months with all PCR's alive NED. This outcome was no different than our previous experience with combination chemotherapy alone. Toxicities seen included leukopenia, thrombocytopenia, nausea, vomiting, and weight loss. However, these side effects were manageable. Two non-tumor deaths occurred. This study demonstrates the feasibility of combining drug and radiation therapy concurrently in the treatment of ovarian cancer; further research is needed to explore different sequencing and dose levels that could improve the outcome

    Background: A considerable amount of experimental and clinical data prove the cytoprotective effect of amifostine on normal tissue exposed to different types of antineoplastic treatments. The present study examines its influence on the short-term toxicity of either radiotherapy alone or combined radio-chemotherapy in patients with advanced head and neck cancer. Patients and methods: Twenty-three patients with advanced head and neck cancer, mainly Stage III and IV, were treated with preoperative radiation (n=1), pre- as well as postoperative radiotherapy (n=5), postoperative radiation (n=9) or combined postoperative radio-chemotherapy (n=6). Before each radiation application a total dose of 500 mg amifostine was administered intravenously over 15 minutes. The documentation of this unselected patient group was compared retrospectively to a historical control group comprising 17 patients. Results: In 15 patients (65%) of the amifostine group, therapy induced side effects such as mucositis and dermatitis of WHO Grade {<=}2 were detected, requiring interruptions of the radiotherapy (mean: 6.5, maximum 17 days). No mucosa or dermatologic toxicity of WHO Grade 3 or 4 was observed in this group. Significantly more acute toxicity was detected in the historical control group. Stomatitis or epitheliolysis of WHO Grade 3 occurred in 7 patients (41%). The side effects induced by the antineoplastic therapy caused an interruption of treatment in 15 patients (88%) (mean: 16, maximum 40 days; p=0.0016). Conclusion: The application of amifostine before each radiation treatment seems to result in a distinct reduction of short-term toxicity of radiotherapy or combined radio-chemotherapy in patients with head and neck cancer, allowing for a better adherence to the planned radiation time schedule.

  7. A multi-institutional survey of the effectiveness of chemotherapy combined with radiotherapy for patients with nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Previous randomized trials have shown a survival advantage of concurrent platinum-based chemoradiotherapy with or without adjuvant chemotherapy for advanced nasopharyngeal cancer. Applicability of these data to a Japanese population is an important issue which remains to be solved. A retrospective survey of treatment of patients with nasopharyngeal cancer in 17 institutions in Japan was done with special reference to the relationship between the type of chemotherapy and survival outcome. Chemotherapy used was classified according to: (i) whether≥2 courses of platinum plus 5-fluorouracil (FP) was given; or (ii) whether platinum was administered concurrently with radiotherapy (RT). This resulted in three groups being produced consisting of (i)/(ii)=YES/YES, other miscellaneous (MISC) and RT alone. Of 333 evaluable replies, 67 patients (20%) corresponded to the YES/YES, 192 (58%) to the MISC and 74 (22%) to the RT alone group. The YES/YES group achieved a better overall survival than RT alone for patients with intermediate stage (T3N0 or T1-3N1, 81.9 versus 60.7% at 5 years, P=0.042) and advanced stage (T4 or N2/3, 56.6 versus 31.5%, P=0.017) disease. The MISC group achieved an almost identical survival rate to that in the YES/YES group for patients with intermediate stage disease (81.9% at 5 years, P=0.968), whereas it was not significantly different from that of the RT alone group for patients with advanced stage disease (44.0%, P=0.261). The results of this survey mirrored the data from previous randomized trials for patients with intermediate and advanced stage nasopharyngeal cancer in Japan. However, confirmatory prospective trials are required to test the efficacy of less toxic approaches for patients with intermediate stage disease. (authors)

    Authors reported results of three different therapies for bladder cancer. 1. Between September 1979 and March 1990, 45 patients with muscle-invasive bladder cancer were treated with intra-arterial doxorubicin (ADM) chemotherapy plus low-dose irradiation. ADM was administered intraarterially at a dose of 20 or 30 mg/body/day from day 1 to 3. Radiotherapy was given at a dose of 2 Gy/session concomitant with intra-arterial administration. Twenty-eight patients achieved complete response (CR) and in all of them, a functional bladder could be preserved. The median follow-up was 9.8 years. Of the 45 patients, 13 died of cancer, including 3 of the 28 with CR. The 10-year cause-specific survival rate of patients with CR was 90%. In contrast, the 10-year survival rate of 17 patients who did not achieve CR was 34%. 2. Authors have treated 21 patients who had locally advanced bladder cancer with this regimen. As an induction therapy, the intra-arterial chemotherapy consisted of 15 mg/m{sup 2}/day pirarubicin (THP) and 25 mg/m{sup 2}/day cisplatin (CDDP) plus 2 Gy of irradiation, which was given just before each chemotherapy session. As a maintenance treatment, patients were treated with THP once a month for 2 years. Among these patients, 19 achieved CR while 2 did not. One patient with CR had relapsed lung metastases 24 months after treatment and underwent thoracotomy. Only one patient who did not achieved CR died of cancer, while the remaining 19 patients show no evidence of disease and were able to preserve a functional bladder. 3. Nine patients were treated with glutathione and compared with 15 patients who were treated with the same regimen but without glutathione. The two groups did not differ regarding CR rate, however the incidence of neurotoxicity among patients receiving glutathione was significantly lower than that among patients who did not receive glutathione.

  9. Naso pharyngeal carcinoma. Modalities of radiation therapy and combinations of radiotherapy and chemotherapy: state of art and perspectives

    International Nuclear Information System (INIS)

    Nasopharyngeal carcinoma (NPC) is a highly radiosensitive and chemo-sensitive. In the patient with locally advanced tumours, the results of conventional radiotherapy are unsatisfactory with significant rates of both local recurrences and distant metastases. The aim of this review is to report the innovative strategies for treatment of the nasopharyngeal carcinoma. Altered fractionation techniques can improve local control. The impact of the innovative techniques, including conformal radiation, stereotactic radiation and IMRT, on survival, must be evaluated in randomized trials. The encouraging early results obtained with concurrent (more than sequential) chemotherapy and radiotherapy must be confirmed in prospective randomized trial in endemic areas. (authors)

  10. Combination chemotherapy including high dose methotrexate and radiotherapy, in the treatment of small cell carcinoma of the lung

    International Nuclear Information System (INIS)

    Twenty-nine (88%) of thirty-three patients who were treated with multiple drug chemotherapy, including high dose methotrexate, and radiotherapy for small cell carcinoma of the lung showed significant improvement in their clinical condition and quality of life. Treatment was well tolerated and toxicity acceptable. Cerebral metastases were not detected in any patient on presentation and only developed in three patients (9%). Little information exists regarding the use of high dose methotrexate in small cell carcinoma of the lung. There is no evidence, on the data available, that high dose methotrexate is any more effective than conventional doses. (author)

  13. Bronchial artery infusion of Gemcitabine and Cisplatin combined with systemic chemotherapy for advanced non-small cell lung cancer: its short-term efficacy

    International Nuclear Information System (INIS)

    Objective: To assess the short-term efficacy of bronchial artery infusion (BAI) of Gemcitabine (GEM) plus Cisplatin (DDP) combined with systemic chemotherapy of GEM for advanced non-small cell lung cancer (NSCLC). Methods: A total of 60 patients with pathologically proved primary NSCLC were randomly selected. BAI with GEM (1000 mg/m2) and DDP (DDP 50 mg/m2) was performed on the first day, and systemic chemotherapy of GEM (1000 mg/m2) was carried out on the eighth day. The clinical results were analyzed. Results: Of the 60 patients, CR, PR, SD and PD were obtained in 3, 35, 17 and 5, respectively, with an overall effective rate of 63%. Twenty-two patients had adenocarcinoma and the effective rate of them was 45%. Thirty-eight patients had squamous cell carcinoma and their effective rate was 74%. The difference in the effective rate between the above two pathologic types was significant (P<0.05). Central type lung cancer was seen in 37 cases, their effective rate was 73%. The peripheral type lung cancer was seen in the remaining 23 patients and the effective rate was 48%. The difference in the effective rate was statistically significant between the central type and the peripheral type (P<0.05). Conclusion: The combination of bronchial artery infusion with systemic chemotherapy by using GP plan is an effective, feasible approach in the treatment of advanced non-small cell lung cancer. The short-term efficacy of the treatment bears a close relationship to the anatomical location and pathological type of the cancer. (authors)

This trial is an open, international multicenter, single-arm clinical study that assesses the safety and efficacy of first-line bevacizumab-based therapy in advanced NSCLC. Methods Twenty-five Chinese patients with advanced non-squamous NSCLC received bevacizumab (15 mg/kg combined with chemotherapy (carboplatin plus paclitaxel treatment from August 2007 to February 2008. Adverse effects (AEs, objective response rate (ORR, median time to progression (TTP, and overall survival (OS were measured. Results AEs were generally mild and reversible. The most frequent AEs were alopecia, peripheral neuropathy, rash, proteinuria, nausea/vomitting, fatigue, myalgia, bleeding, and hypertension. The partial remission and stable disease rates were 68% and 28%, respectively. The median TTP and OS of all patients were 11.2 and 19.3 months, respectively. Conclusion Bevacizumab combined with carboplatin-based chemotherapy may be well tolerated and beneficial for Chinese patients with non-squamous NSCLC.

  16. Combined hyperfractionated irradiation and protracted infusion chemotherapy in invasive bladder cancer with conservative intent. Phase I study

    International Nuclear Information System (INIS)

    Purpose: The aim of this study is to define the optimal schedule of chemo-radiotherapy in selective bladder preservation. Materials and Methods: >From November 1992 to February 1996, 34 patients with invasive transitional cell bladder carcinoma have been accrued in this dose-finding study. After aggressive TUR, patients underwent 2 cycles of MCV chemotherapy (CT) followed by radiotherapy (RT) with concomitant protracted venous infusion (PVI) of cisplatin (cDDP) and 5-fluorouracil (5-FU), which was started within 30-40 days from the completion of CT. Fifty Gy were given to the small pelvis followed by 20 Gy to the bladder (1 Gy x 3 fractions a day/5 days a week for 4.5 weeks). The following levels of doses have been tested: 5-FU 180 mg/sm/die and cDDP 4mg/sm/die (3 pts), cDDP 5mg/sm/die (3 pts), cDDP 6mg/sm/die (3 pts); cDDP 6 mg/sm/die and 5-FU 200 mg/sm/die (6 pts), 5-FU 220 mg/sm/die (6 pts), cDDP 5 mg/sm/die and 5-FU 220 mg/sm/die (4 pts). In the remaining 9 patients MCV CT has been omitted for medical reasons and/or age >75 years. In the MCV CT group, we have treated 25 patients, 22 males and 3 females (age range 53-75 years). Nine cases were T2N0M0, 2 T2N1M0, 13 T3N0M0, 1 T4aN0M0, 19 were G2 and 6 G3. In the group without MCV, 8 male and 1 female (age range 62-80 years), 3 were T2N0M0 and 6 T3N0M0, 4 G2 and 5 G3. RT-CT has been performed at doses of cDDP 5 mg/sm/die and 5-FU 200 mg/sm/die. Results: All patients are evaluable for toxicity. Very mild rectal tenesmus and dysuria were observed, except for the dose level cDDP 6 mg/sm/die and 5-FU 220 mg/sm/die, where the treatment has been interrupted for 5-15 days in all patients, due to grade III-IV tenesmus and dysuria and in(4(6)) patients also for leukopenia and/or thrombocytopenia grade III. Only in one patient at the first level of dose, RT-CT was stopped at the dosage of 58 Gy because of grade IV bone marrow depletion. We suggest to consider cDDP 5 mg/sm/die and 5-FU 220 mg/sm/die as the maximum tolerated

  17. Neoadjuvant intra-arterial chemotherapy combined with radiotherapy and surgery in patients with advanced maxillary sinus cancer

    International Nuclear Information System (INIS)

    The optimal treatment of advanced maxillary sinus cancer has been challenging for several decades. Intra-arterial chemotherapy (IAC) for head and neck cancer has been controversial. We have analyzed the long-term outcome of neoadjuvant IAC followed by radiation therapy (RT) and surgery. Twenty-seven patients with advanced maxillary sinus cancer were treated between 1989 and 2002. Five-fluorouracil (5-FU, 500 mg/m2) was infused intra-arterially, and followed by RT (total 50.4 Gy/28 fractions). A planned surgery was performed 3 to 4 weeks after completion of IAC and RT. At a median follow-up of 77 months (range, 12 to 169 months), the 5-year rates of overall survival in all patients were 63%. The 5-year rates of overall survival of stage T3/T4 patients were 70.0% and 58.8%, respectively. Seven of fourteen patients with disease recurrence had a local recurrence alone. The 5-year actuarial local control rates in patients with stage T3/T4, and in all patients were 20.0%, 32.3%, and 27.4%, respectively. Overall response rate after the completion of IAC and RT was 70.3%. During the follow-up, seven patients (25.9%) showed mild to moderate late complications. The tumor extent (i.e., the involvement of either orbit and/or base of skull) appeared to be related with local recurrence. Neoadjuvant IAC with 5-FU followed by RT and surgery may be effective to improve local tumor control in the patients with advanced maxillary sinus cancer. However, local failure was still the major cause of death. Further investigations are required to determine the optimal treatment schedule, radiotherapy techniques and chemotherapy regimens.

  19. The survival outcomes and prognosis of stage IV non-small-cell lung cancer treated with thoracic three-dimensional radiotherapy combined with chemotherapy

    International Nuclear Information System (INIS)

    The impact of thoracic three-dimensional radiotherapy on the prognosis for stage IV non-small-cell lung cancer is unclear. This study is to investigate survival outcomes and prognosis in patients with stage IV non-small cell lung cancer (NSCLC) treated with thoracic three-dimensional radiotherapy and systemic chemotherapy. Ninety three patients with stage IV NSCLC had received at least four cycles of chemotherapy and thoracic three-dimensional radiotherapy of ≥40 Gy on primary tumors. The data from these patients were retrospectively analyzed. Of the 93 patients, the median survival time (MST) was 14.0 months, and the 1, 2, and 3-year survival rates were 54.8%, 20.4%, and 12.9%, respectively. The MST of patients received radiation dose to primary tumor ≥63Gy and <63 Gy for primary tumor were 15.0 and 8.0 months, respectively (P = 0.001). Patients had metastasis to a single site and lower tumor volume (<170 cm3) also produced longer overall survival time (P = 0.002, P = 0.020, respectively). For patients with metastasis at a single site, thoracic radiation dose ≥63 Gy remained a prognostic factor for better overall survival (P = 0.030); patients with metastases at multiple sites, radiation dose ≥63 Gy had a trend to improve overall survival (P = 0.062). A multivariate analysis showed that radiation dose ≥63 Gy (P = 0.017) and metastasis to a single site (P = 0.038) are associated with better overall survival, and the volume of primary tumor was marginally correlated with OS (P = 0.054). In combination with systemic chemotherapy, radiation dose ≥63 Gy on primary tumor and metastasis to a single site are significant factors for better OS, aggressive thoracic radiotherapy may have an important role in improving OS

  20. Evaluation of paclitaxel and carboplatin versus combination chemotherapy with fluorouracil doxorubicin and cyclophosphamide as a neoadjuvant therapy in patients with inoperable breast cancer

    International Nuclear Information System (INIS)

    To compare the results of patients with locally advanced breast cancer receiving two different regimens Fluorouracil, Doxorubicin and Cyclophosphamide (FAC) and Paclitaxel and Carboplatin. Study Design: Comparative study. Place and Duration of Study: The Oncology Department, Institute of Nuclear Medicine and Oncology (INMOL), Lahore, from March 2007 to September 2008. Methodology: Patients with inoperable locally advanced breast cancer of stage were included. Sixteen patients were given FAC regimen and 9 patients were given Paclitaxel and Carboplatin, each combination was cycled after 21 days for four times. Before enrollment, detailed medical histories, physical examinations and performance status assessments were done as well as post chemotherapy evaluation with regular follow-up visits was done. Complete Response (CR, 100%) is defined as the disappearance of all known disease parameter i.e. disappearance in detectable tumour size, node free disease and surgery is possible. Paratial Response (PR, > 50%) was defined by 50% or greater decrease in the sum of the areas of bidimensionally measured lesions i.e. change of N2 to N1 or no status and some surgical procedure is possible to down stage the disease. Minor Response (MR) was defined as a decrease in the tumour insufficient to quality for partial resp once. Static disease or no evaluable reflected no significant change in disease and no evidence of new disease. Progression of disease (> 25%) was defined as a 25% or greater increase in the area of any lesion > 2 cm or in the sum of the products of the individual lesions or the appearance of new malignant lesions, surgery not possible. Results: Twenty five patients completed neoadjuvant chemotherapy. Sixteen (66%) patients received FAC and 9 (37%) patients received PC chemotherapy. Overall CR (breast and axilla) was 54%, PR was 16% and minor response (MR) was 8%. FAC treatment induced more emesis, mucositis, alopecia and cardiotoxicity. No death occurred

  1. Involved-field radiotherapy (IFRT) versus elective nodal irradiation (ENI) in combination with concurrent chemotherapy for 239 esophageal cancers: a single institutional retrospective study

    International Nuclear Information System (INIS)

    This retrospective study on early and locally advanced esophageal cancer was conducted to evaluate locoregional failure and its impact on survival by comparing involved field radiotherapy (IFRT) with elective nodal irradiation (ENI) in combination with concurrent chemotherapy. We assessed all patients with esophageal cancer of stages I-IV treated with definitive radiotherapy from June 2000 to March 2014. Between 2000 and 2011, ENI was used for all cases excluding high age cases. After Feb 2011, a prospective study about IFRT was started, and therefore IFRT was used since then for all cases. Concurrent chemotherapy regimen was nedaplatin (80 mg/m2 at D1 and D29) and 5-fluorouracil (800 mg/m2 at D1-4 and D29-32). Of the 239 consecutive patients assessed (120 ENI vs. 119 IFRT), 59 patients (24.7 %) had stage IV disease and all patients received at least one cycle of chemotherapy. The median follow-up time for survivors was 34.0 months. There were differences in 3-year local control (44.8 % vs. 55.5 %, p = 0.039), distant control (53.8 % vs. 69.9 %, p = 0.021) and overall survival (34.8 % vs. 51.6 %, p = 0.087) rates between ENI vs. IFRT, respectively. Patients treated with IFRT (8 %) demonstrated a significantly lower risk (p = 0.047) of high grade late toxicities than with ENI (16 %). IFRT did not increase the risk of initially uninvolved or isolated nodal failures (27.5 % in ENI and 13.4 % in IFRT). Nodal failure rates in clinically uninvolved nodal stations were not increased with IFRT when compared to ENI. IFRT also resulted in significantly decreased esophageal toxicity, suggesting that IFRT may allow for integration of concurrent systemic chemotherapy in a greater proportion of patients. Both tendencies of improved loco-regional progression-free survival and a significant increased overall survival rate favored the IFRT arm over the ENI arm in this study

    Full Text Available Abstract Background Erlotinib and pemetrexed have been approved for the second-line treatment of non-small cell lung cancer (NSCLC. These two agents have different mechanisms of action. Combined treatment with erlotinib and pemetrexed could potentially augment the antitumor activity of either agent alone. In the present study, we investigated the safety profile of combined administration of the two agents in pretreated NSCLC patients. Methods A phase I dose-finding study (Trial registration: UMIN000002900 was performed in patients with stage III/IV nonsquamous NSCLC whose disease had progressed on or after receiving first-line chemotherapy. Patients received 500 mg/m2 of pemetrexed intravenously every 21 days and erlotinib (100 mg at Level 1 and 150 mg at Level 2 orally on days 2–16. Results Twelve patients, nine males and three females, were recruited. Patient characteristics included a median age of 66 years (range, 48–78 years, stage IV disease (nine cases, adenocarcinoma (seven cases and activating mutation-positives in the epidermal growth factor receptor gene (two cases. Treatment was well-tolerated, and the recommended dose of erlotinib was fixed at 150 mg. Dose-limiting toxicities were experienced in three patients and included: grade 3 elevation of serum alanine aminotransferase, repetitive grade 4 neutropenia that required reduction of the second dose of pemetrexed and grade 3 diarrhea. No patient experienced drug-induced interstitial lung disease. Three patients achieved a partial response and stable disease was maintained in five patients. Conclusions Combination chemotherapy of intermittent erlotinib with pemetrexed was well-tolerated, with promising efficacy against pretreated advanced nonsquamous NSCLC.

    Erlotinib and pemetrexed have been approved for the second-line treatment of non-small cell lung cancer (NSCLC). These two agents have different mechanisms of action. Combined treatment with erlotinib and pemetrexed could potentially augment the antitumor activity of either agent alone.

  4. Influence of age and duration of follow-up on lung function after combined chemotherapy for Hodgkin's disease

    International Nuclear Information System (INIS)

    Pulmonary function was studied in 48 patients 4-13 yrs after treatment for Hodgkin's disease with mantle-field irradiation followed by standard mechlorethamine, Oncovin, procarbazine and prednisone (MOPP) chemotherapy. The patients were found to have a restrictive lung disease suggestive of pulmonary fibrosis. Low age at therapy (≤30 yrs, median 24 yrs) was associated with a significantly more pronounced restrictive lung function impariment than older age (>30 yrs, median 40 yrs) suggesting a higher susceptibility to the pulmonary side-effects of therapy. In addition younger smokers had a significantly greater reduction in diffusion capacity and forced expiratory volume in one second than older smokers, suggesting a higher susceptibility to the additional adverse effect of smoking. With longer follow-up nonsmokers had an increase in static lung volumes. It is suggested that this may be the result of more frequent pulmonary infections in sucgh patients as compared with the general population. However, the duration of follow-up was not associated with changes in other indices of lung function. (author)

  5. Identification of new tumor associated antigens and their usage for new therapeutic strategies based on the combination of chemotherapy and immunotherapy for colorectal cancer patients

    International Nuclear Information System (INIS)

    The main general objective of this project was to characterize a new colorectal carcinoma (CRC) tumor-associated antigen (TAA) and validate a new therapeutic strategy combining chemotherapy and tumor vaccination for the treatment of cancer patients. To this purpose a strategic interaction between Drs. Proietti/Maccali at the ISS and the group of Drs. Rosenberg/Robbins at the NIH was established. A stage of Dr. Maccalli at the NIH allowed to carry out the first steps for the identification and the initial characterization of the CRC TAA named COA-1. A laboratory meeting with Dr. Robbins has been planned on May 24-25 2006 at the ISS, during the International Meeting on Immunotherapy of Cancer: Challenges and Needs, for discussing results and perspectives of this research project

    This meta-analysis evaluates the clinical evidence for the addition of traditional medicines (TMs) to oxaliplatin-based regimens for colorectal cancer (CRC) in terms of tumor response rate (TRR). Eight electronic databases were searched for randomized controlled trials of oxaliplatin-based chemotherapy combined with TMs compared to the same oxaliplatin-based regimen. Data on TRR from 42 randomized controlled trials were analyzed using Review Manager 5.1. Studies were conducted in China or Japan. Publication bias was not evident. The meta-analyses suggest that the combination of the TMs with oxaliplatin-based regimens increased TRR in the palliative treatment of CRC (risk ratio [RR] 1.31 [1.20-1.42], I(2) = 0%). Benefits were evident for both injection products (RR 1.36 [1.18-1.57], I(2) = 0%) and orally administered TMs (RR 1.27 [1.15-1.41], I(2) = 0%). Further sensitivity analysis of specific plant-based TMs found that Paeonia, Curcuma, and Sophora produced consistently higher contributions to the RR results. Compounds in each of these TMs have shown growth-inhibitory effects in CRC cell-line studies. Specific combinations of TMs appeared to produce higher contributions to TRR than the TMs individually. Notable among these was the combination of Hedyotis, Astragalus, and Scutellaria. PMID:26254190

  7. Treatment of locally advanced carcinomas of head and neck with intensity-modulated radiation therapy (IMRT) in combination with cetuximab and chemotherapy: the REACH protocol

    International Nuclear Information System (INIS)

    Primary treatment of carcinoma of the oro-/hypopharynx or larynx may consist of combined platinum-containing chemoradiotherapy. In order to improve clinical outcome (i.e. local control/overall survival), combined therapy is intensified by the addition of the EGFR inhibitor cetuximab (Erbitux®). Radiation therapy (RT) is carried out as intensity-modulated RT (IMRT) to avoid higher grade acute and late toxicity by sparing of surrounding normal tissues. The REACH study is a prospective phase II study combining chemoradiotherapy with carboplatin/5-Fluorouracil (5-FU) and the monoclonal epidermal growth factor-receptor (EGFR) antibody cetuximab (Erbitux®) as intensity-modulated radiation therapy in patients with locally advanced squamous-cell carcinomas of oropharynx, hypopharynx or larynx. Patients receive weekly chemotherapy infusions in the 1st and 5th week of RT. Additionally, cetuximab is administered weekly throughout the treatment course. IMRT is delivered as in a classical concomitant boost concept (bid from fraction 16) to a total dose of 69,9 Gy. Primary endpoint of the trial is local-regional control (LRC). Disease-free survival, progression-free survival, overall survival, toxicity, proteomic and genomic analyses are secondary endpoints. The aim is to explore the efficacy as well as the safety and feasibility of this combined radioimmunchemotherapy in order to improve the outcome of patients with advanced head and neck cancer.

    AIM: In nonresectable cholangiocellular carcinoma (CCC)therapeutic options are limited. Recently, systemic chemotherapy has shown response rates of up to 30%.Additional regional therapy of the arterially hyper vascularized hepatic tumors might represent a rational approach in an attempt to further improve response and palliation. Hence, a protocol combining transarterial chemoembolization and systemic chemotherapy was applied in patients with CCC limited to the liver.METHODS: Eight patients (6 women, 2 men, mean age 62 years) with nonresectable CCC received systemic chemotherapy (gemcitabine 1 000 mg/m2) and additional transarterial chemoembolization procedures (50 mg/m2cisplatin, 50 mg/m2 doxorubicin, up to 600 mg degradable starch microspheres). Clinical follow-up of patients, tumor markers, CT and ultrasound were performed to evaluate maximum response and toxicity.RESULTS: Both systemic and regional therapies were tolerated well; no severe toxicity (WHO Ⅲ/Ⅳ) was encountered. Nausea and fever were the most commonly observed side effects. A progressive rarefication of the intrahepatic arteries limited the maximum number of chemoembolization procedures in 4 patients. A median of 2 chemoembolization cycles (range, 1-3) and a median of 6.5 gemcitabine cycles (range, 4-11) were administered.Complete responses were not achieved. As maximum response, partial responses were achieved in 3 cases,stable diseases in 5 cases. Two patients died from progressive disease after 9 and 10 mo. Six patients are still alive. The current median survival is 12 mo (range, 9-18); the median time to tumor progression is 7 mo (range, 3-18). Seven patients suffered from tumor-related symptoms prior to therapy, 3 of these experienced a treatment-related clinical relief. In one patient the tumor became resectable under therapy and was successfully removed after 10 mo.CONCLUSION: The present results indicate that a combination of systemic gemcitabine therapy and repeated regional

    Background and objective Recent studies have showed that combination of chemotherapy and radiotherapy might result in better outcome for locally advanced non-small cell lung cancer (NSCLC). The aim of this study is to determine the maximal tolerance dose (MTD) and efficacy of full-dose gemcitabine and oxaliplatin when given concurrently with 3-dimentional radiation therapy (3D-RT) for locally advanced NSCLC. Methods Oxaliplatin was administered at a fixed dose of 130 mg/m2, and gemcitabine was administered at a starting dose of 800 mg/m2 with an incremental dose gradient of 200 mg/m2 for 3 dose levels. MTD was defined as the immediate dose level lower than the dose at which dose-limiting toxicity (DLT) occurred in more than one-third of the patients. The chemotherapy was administered at 3-week cycle. The RT was given as 3-D conformal manner at a single daily dose of 2 Gy for 5 days per week. Results Twenty-two patients were evaluable and distributed to three different dose levels: 6 at level 1, 8 at level 2 and 8 at level 3. Pulmonary toxicity, esophageal and hematologic toxicity were the main DLT. Grade Ⅲ acute pulmonary toxicity occurred in one patient each at level 2 and level 3, both with V20>20%, and grade Ⅲ esophagitis in two patients at level 3. The MTD of gemcitabine in this study was 1000 mg/m2. The overall response rate was 75.0% (9/12). The 1- and 2-year survival rate was 70.0% and 30.5% respectively. The median time to progression was 8.7 months (range 5--11.8 months). Conclusion With reduced radiation volume, gemcitabine of 1000 mg/m2 in combination with oxaliplatin of 130 mg/m2 was effective and could be safely administered for NSCLC.

  12. Activity of oxantel pamoate monotherapy and combination chemotherapy against Trichuris muris and hookworms: revival of an old drug.

    Directory of Open Access Journals (Sweden)

    Jennifer Keiser

    Full Text Available BACKGROUND: It is widely recognized that only a handful of drugs are available against soil-transmitted helminthiasis, all of which are characterized by a low efficacy against Trichuris trichiura, when administered as single doses. The re-evaluation of old, forgotten drugs is a promising strategy to identify alternative anthelminthic drug candidates or drug combinations. METHODOLOGY: We studied the activity of the veterinary drug oxantel pamoate against Trichuris muris, Ancylostoma ceylanicum and Necator americanus in vitro and in vivo. In addition, the dose-effect of oxantel pamoate combined with albendazole, mebendazole, levamisole, pyrantel pamoate and ivermectin was studied against T. muris in vitro and additive or synergistic combinations were followed up in vivo. PRINCIPAL FINDINGS: We calculated an ED50 of 4.7 mg/kg for oxantel pamoate against T. muris in mice. Combinations of oxantel pamoate with pyrantel pamoate behaved antagonistically in vitro (combination index (CI = 2.53. Oxantel pamoate combined with levamisole, albendazole or ivermectin using ratios based on their ED50s revealed antagonistic effects in vivo (CI = 1.27, 1.90 and 1.27, respectively. A highly synergistic effect (CI = 0.15 was observed when oxantel pamoate-mebendazole was administered to T. muris-infected mice. Oxantel pamoate (10 mg/kg lacked activity against Ancylostoma ceylanicum and Necator americanus in vivo. CONCLUSION/SIGNIFICANCE: Our study confirms the excellent trichuricidal properties of oxantel pamoate. Since the drug lacks activity against hookworms it is necessary to combine oxantel pamoate with a partner drug with anti-hookworm properties. Synergistic effects were observed for oxantel pamoate-mebendazole, hence this combination should be studied in more detail. Since, of the standard drugs, albendazole has the highest efficacy against hookworms, additional investigations on the combination effect of oxantel pamoate-albendazole should be

  13. The in vitro effect of gefitinib ('Iressa') alone and in combination with cytotoxic chemotherapy on human solid tumours

    International Nuclear Information System (INIS)

    Activation of the epidermal growth factor receptor (EGFR) triggers downstream signaling pathways that regulate many cellular processes involved in tumour survival and growth. Gefitinib ('Iressa') is an orally active tyrosine kinase inhibitor (TKI) targeted to the ATP-binding domain of EGFR (HER1; erbB1). In this study we have used a standardised ATP-based tumour chemosensitivity assay (ATP-TCA) to measure the activity of gefitinib alone or in combination with different cytotoxic drugs (cisplatin, gemcitabine, oxaliplatin and treosulfan) against a variety of solid tumours (n = 86), including breast, colorectal, oesophageal and ovarian cancer, carcinoma of unknown primary site, cutaneous and uveal melanoma, non-small cell lung cancer (NSCLC) and sarcoma. The IC50 and IC90 were calculated for each single agent or combination. To allow comparison between samples the IndexSUM was calculated based on the percentage tumour growth inhibition (TGI) at each test drug concentration (TDC). Gefitinib was tested at concentrations ranging from 0.0625–2 microM (TDC = 0.446 microg/ml). This study represents the first use of a TKI in the assay. There was heterogeneity in the degree of TGI observed when tumours were tested against single agent gefitinib. 7% (6/86) of tumours exhibited considerable inhibition, but most showed a more modest response resulting in a low TGI. The median IC50 value for single agent gefitinib in all tumours tested was 3.98 microM. Interestingly, gefitinib had both positive and negative effects when used in combination with different cytotoxics. In 59% (45/76) of tumours tested, the addition of gefitinib appeared to potentiate the effect of the cytotoxic agent or combination (of these, 11% (5/45) had a >50% decrease in their IndexSUM). In 38% of tumours (29/76), the TGI was decreased when the combination of gefitinib + cytotoxic was used in comparison to the cytotoxic alone. In the remaining 3% (2/76) there was no change observed. The in vitro

    Since toxicity and resistance are the major drawbacks of current antileishmanial drugs, studies have been recently focused on combination therapy in fight against leishmaniasis. Combination therapy generally provides opportunity to decrease toxicity of applied agents and enhance their antimicrobial performance. Moreover, this method can be effective in preventing drug resistance. Highly antileishmanial effects of silver doped titanium dioxide nanoparticles (TiAgNps) and Nigella sativa oil were demonstrated in previous studies. However, toxicity is still an important factor preventing use of these molecules in clinic. By considering high antileishmanial potential of each agent and basic principles of combination therapy, we propose that use of combinations including non-toxic concentrations of TiAgNps and N. sativa oil may compose more effective and safer formulations against Leishmania parasites. Therefore, the main goal of the present study was to investigate antileishmanial effects of non-toxic concentrations of TiAgNps and Nigella sativa oil combinations on promastigote and amastigote-macrophage culture systems and also to develop nanotechnology based new antileishmanial strategies against Cutaneous Leishmaniasis. Numerous parameters such as proliferation, metabolic activity, apoptosis, amastigote-promastigote conversion, infection index analysis and nitric oxide production were used to detect antileishmanial efficacies of combinations. Investigated all parameters demonstrated that TiAgNps-N. sativa oil combinations had significant antileishmanial effect on each life forms of parasites. Tested combinations were found to decrease proliferation rates of Leishmania tropica promastigotes in a range between 1,5-25 folds and metabolic activity values between 2 and 4 folds indicating that combination applications lead to virtually inhibition of promastigotes and elimination of parasites were directly related to apoptosis manner. TiAgNps-N. sativa combinations also

  16. Hyperthermia and chemotherapy agent

    International Nuclear Information System (INIS)

    The use of chemotherapeutic agents for the treatment of cancer dates back to the late 19th century, but the modern era of chemotherapy drugs was ushered in during the 1940's with the development of the polyfunctional alkylating agent. Since then, numerous classes of drugs have evolved and the combined use of antineoplastic agents with other treatment modalities such as radiation or heat, remains a large relatively unexplored area. This approach, combining local hyperthermia with chemotherapy agents affords a measure of targeting and selective toxicity not previously available for drugs. In this paper, the effects of adriamycin, bleomycin and cis-platinum are examined. The adjuvant use of heat may also reverse the resistance of hypoxic cells noted for some chemotherapy agents

  17. Combined conservative surgery, chemotherapy and radiation therapy in treatment of the breast cancer patient: the influence of the interval between surgery and start of irradiation

    International Nuclear Information System (INIS)

    Purpose: To analyze our experience treating breast cancer patients with combined breast conserving surgery, chemotherapy and radiation therapy in the light of considerable discussion on the role of the interval between surgery and radiation therapy (S-RT). Materials and Methods: Between 1985 and 1992, 100 patients with invasive breast cancer underwent radiation treatment at our institution after conservative surgery with axillary dissection and some form of chemotherapy. Criteria for inclusion in this retrospective analysis were: Stage M0, no simultaneous malignancies, gross total resection of primary and involved lymph nodes, at least three cycles of postoperative polychemotherapy, complete radiation treatment, complete follow-up information. Seventy-four patients fulfilling these criteria form the basis of this report. For patients alive at last observation date, median follow-up time was five years (i.e., 59 months; range, 36-112 months). Age at diagnosis ranged between 20 and 69 years (median, 48 years). Fifty-four patients were pre- or perimenopausal (73%) and 20 were postmenopausal (27%). Tumors were staged using the AJCC-system. Distribution of T-Stage was: T1 (n=36), T2 (n=37), T3 (n=1). In 95% of patients, axillary lymph nodes were positive: 1-3 nodes (n=50), ≥ 4 nodes (n=20), and 0 nodes (n=3). Thus, 91% of patients were Stage II. In 65% of patients, final pathological margins were negative. Margins showed invasive and intraductal carcinoma in 5 and 11% of cases, respectively (margins unknown in 19%). Chemotherapy regimens and doses varied according to the referring physicians as well as during the study period. Seventy percent of patients received six cycles of chemotherapy (predominan CMF) before onset of irradiation. The median S-RT interval was 20.5 weeks (range, 8.4-31.9 weeks). Usually, the breast was treated to 50 Gy, 2 Gy per fraction, five fractions per week, using Cobalt-60 (n=66) or 5 MeV photons (n=8). Then the tumor bed was boosted with

    Full Text Available Rudolph M Navari Cancer Care Program, Eastern Europe, World Health Organization, Mishawaka, IN, USA; Indiana University School of Medicine, South Bend, IN, USA; South Bend Medical Services Corporation, IN, USA Abstract: Chemotherapy-induced nausea and vomiting (CINV is associated with a significant deterioration in quality of life. The emetogenicity of the chemotherapeutic agents, repeated chemotherapy cycles, and patient risk factors significantly influence CINV. The use of a combination of a 5-hydroxytryptamine-3 (5-HT3 receptor antagonists, dexamethasone, and a neurokinin-1 (NK-1 receptor antagonist has significantly improved the control of acute and delayed emesis in single-day chemotherapy. Palonosetron, a second generation 5-HT3 receptor antagonist with a different half-life, different binding capacity, and a different mechanism of action than the first generation 5-HT3 receptor antagonists, appears to be the most effective agent in its class. Netupitant, is a new NK-1 receptor antagonist with a high binding affinity, a long half-life of 90 hours, is metabolized by CYP3A4, and is an inhibitor of CYP3A4. NEPA is an oral fixed-dose combination of netupitant and palonosetron which has recently been employed in Phase II and Phase III clinical trials for the prevention of CINV in patients receiving moderately and highly emetogenic chemotherapy (MEC and HEC. The clinical trials demonstrated that NEPA (300 mg of netupitant plus 0.50 mg of palonosetron significantly improved the prevention of CINV compared to the use of palonosetron alone in patients receiving either HEC or MEC. The clinical efficacy was maintained over multiple cycles of chemotherapy. NEPA (Akynzeo® has recently been approved by the Food and Drug Administration (FDA to treat nausea and vomiting in patients undergoing cancer chemotherapy.

    The introduction of anthracyclines to adjuvant chemotherapy has increased survival rates among breast cancer patients. Cyclophosphamide, epirubicin and 5-fluorouracil (CEF) combination therapy is now one of the preferred regimens for treating node-positive breast cancer due to better survival with less toxicity involved. Despite the increasing use of CEF, its potential in causing adverse skeletal effects remains unclear. Using a mature female rat model mimicking the clinical setting, this study examined the effects of CEF treatment on bone and bone marrow in long bones. Following six cycles of CEF treatment (weekly intravenous injections of cyclophosphamide at 10 mg/kg, epirubicin at 2.5 mg/kg and 5-flurouracil at 10 mg/kg), a significant reduction in trabecular bone volume was observed at the metaphysis, which was associated with a reduced serum level of bone formation marker alkaline phosphatase (ALP), increased trends of osteoclast density and osteoclast area at the metaphysis, as well as an increased size of osteoclasts being formed from the bone marrow cells ex vivo. Moreover, a severe reduction of bone marrow cellularity was observed following CEF treatment, which was accompanied by an increase in marrow adipose tissue volume. This increase in marrow adiposity was associated with an expansion in adipocyte size but not in marrow adipocyte density. Overall, this study indicates that six cycles of CEF chemotherapy may induce some bone loss and severe bone marrow damage. Mechanisms for CEF-induced bone/bone marrow pathologies and potential preventive strategies warrant further investigation. PMID:26056019

    Background Relapse remains an obstacle to successful allogeneic haematopoietic stem cell transplantation (alIo-HSCT) for patients with acute leukaemia and no standard treatment is available. We assessed fludarabine and cytarabine with transfusion of donor haematopoietic stem cell in treating the relapse of acute leukaemia after alIo-HSCT.Methods Seven patients, median age 34 years, with relapse of acute leukaemia after alIo-HSCT received combination chemotherapy of fludarabine with cytarabine for 5 days. Five patients suffered from acute myeloid leukaemia (2 refractory) and 2 refractory acute lymphoblastic leukaemia. After the transplantation, the median relapse time was 110 days (range,38-185 days). Two days after chemotherapy, 5 patients received infusion of donor's peripheral blood stem cells, mobilized by granulocyte colony stimulating factor. No prophylactic agents of graft versus host diseases were administered.Results Six patients achieved haematopoietic reconstitution. DNA sequence analysis at day 30 after treatment identified all as full donor chimera type. The median observation time was 189 days. After the treatment, the median time for neutrophilic granulocyte value ≥0.5x109/L and for platelet value >20x109/L were 13 days (range, 10-18 days) and 15 days (range, 11-24 days), respectively. Graft versus host disease occurred in 2 patients (acute) and 3 (chronic). Five patients suffered from pulmonary fungal infection (2 died), 3 haemorrhagic cystitis and 2 cytomegalovirus viraemia. The other patients died of leukaemia related deaths. Three patients with chronic graft versus host disease who had received donor peripheral blood stem cells reinfusion have survived for 375 days, 232 days and 195 days, respectively.Conclusions Fludarabine with cytarabine plus the donor haematopoietic stem cell should be considered as an effective therapeutic regimen for relapse of acute leukaemia after alIo-HSCT. The disease free state of patients may increase, thou.gh with

Numerous national and international cooperative groups and several single institutions were actively involved in performing often cited, high-impact trials, reflecting the fact that NSCLC is a world-wide challenge that requires research collaboration. Platinum-containing combinations have evolved into a standard of care, typically administered concurrently. The issue of radiotherapy fractionation and total dose has also been studied extensively, yet with less conclusive results. Differences in target volume definition have been addressed. However, it was not possible to test all theoretically possible combinations of radiotherapy regimens, drugs and drug doses (lower radiosensitizing doses compared to higher systemically active doses. That is why current guidelines offer physicians a choice of different, presumably equivalent treatment alternatives. This review identifies open questions and strategies for further research.

    Full Text Available Background: The purposes of this study were to examine the impact of chemotherapy treatment on Jordanian cancer patients’ fatigue and to correlate their fatigue with selected sociodemographic variables at the beginning of treatment and after four weeks of treatment. Methods: This was a single group quasi-experimental correlational design study that enrolled 43 patients diagnosed with cancer who required chemotherapy treatment. Fatigue was measured according to the Piper Fatigue Scale (PFS before starting chemotherapy treatment and after four weeks of receiving the first dose of chemotherapy. Data were collected over a period of four weeks and analyzed with descriptive statistics, the paired-sample t-test, and Pearson product-moment correlation. Results: The study included 17 (39.5% males and 26 (60.5% females with a mean age of 45.98 years. Most (n=17 were diagnosed with breast cancer. Obesity was present in about 64.4% of patients. The majority (46% received an anthracycline-based regimen. There were statistically significant differences between respondents’ total mean scores of fatigue pre-treatment and four weeks following chemotherapy treatment (t= -2.31, df=42, P<0.05. In addition, significant differences were found in the scores for behavioral, affective, sensory, and cognitive dimensions subscales (t= -2.24, -2.19, - 2.4, -2.4, df=42, P<0.05 between pre-treatment and four weeks after receiving the first dose of chemotherapy treatment. We observed a significant negative relationship between fatigue scores and hemoglobin levels (r= -0.04, P<0.01. Conclusion: Cancer-related fatigue is common among cancer patients who received chemotherapy and result in substantial adverse physical, behavioral, cognitive and affective consequences for patient. Given the impact of fatigue, treatment options should be routinely considered in the care of patients with cancer.

    Integrins are highly attractive targets in oncology due to their involvement in angiogenesis in a wide spectrum of cancer entities. Among several integrin inhibitors under clinical evaluation, cilengitide is the most promising compound. However, little is known about the cellular processes induced during cilengitide therapy in combination with irradiation and cisplatin in head and neck squamous cell carcinoma (HNSCC). The cytostatic effect of cilengitide was assessed by proliferation assay in the three HNSCC cell lines SCC25, FaDu and CAL27. Combination experiments with cisplatin and irradiation were performed. Possible synergistic effects were calculated in combination index (CI) analyses. Colony forming inhibition was investigated in clonogenic assays. Real-time PCR arrays were used to evaluate target protein gene expression patterns. Flow cytometry was used to detect apoptosis. Used alone, cilengitide has only minor cytotoxic effects in HNSCC cell lines. However, combination with cisplatin resulted in synergistic growth inhibition in all three cell lines. Irradiation showed synergism in short-term experiments and in colony forming assays, an additive effect was detected. Real-time PCR assay detected downregulation of the antiapoptotic protein Bcl-2 after exposure of cells to cilengitide. Cilengitide in combination with cisplatin and irradiation may be a feasible option for the treatment of patients with head and neck cancer. However, further investigations are required to understand the exact mechanism that leads to synergistic cytotoxicity. (orig.)

  8. Results of radiotherapy and combined radiotherapy and chemotherapy of inoperable lung cancer (A joint randomized study in some CMEA member countries, project 9.1.3 of the 9.1 Lung Cancer Program)

    International Nuclear Information System (INIS)

    A comparative analysis is presented of immediate results after radiotherapy and combined treatment (radio- and chemotherapy) in 174 patients with highly differentiated inoperable lung cancer. The data were provided by the participants of joint investigation in some CMEA member countries (Hungary, USSR, Czechoslovakia) during the period of 1976 to 1980. In the randomized study, radiotherapy (a total dose of 60 Gy) was applied in 98 patients, radiotherapy with chemotherapy (methotrexate and 5-fluorouracil) was applied in 76 patients. The comparative analysis showed that the employment of complementary chemotherapy tends to improve the immediate therapeutic effects. In case of highly differentiated planocellular carcinoma a pronounced positive effect was seen in 48.6% of patients as compared to 31.2% of those treated with radiotherapy alone. Nevertheless, with respect to survival rate extension, these differences are not in favor of the combined method of treatment. After conservative treatment (radiotherapy and radiotherapy in combination with chemotherapy) of patients with differentiated types of inoperable lung cancer, a one-year survival rate was recorded in 55.7%, 17.27% of the patients survived for 2 years, and 8.55% for 3 years. In radiotherapy applied alone and in combination, a direct dependence of survival rate extension on therapeutical effects was detected. 49 patients (73.1%) out of 67 exhibiting pronounced immediate effects survived for more than 1 year and 8 patients out of 9 survived for 3 years.

  9. Combined therapy with surgery, radiation and chemotherapy for T3-T4 squamous cell carcinoma of maxillary sinus. National Cancer Center Hospital East experience

    International Nuclear Information System (INIS)

    Since 1960's, many institutes treated carcinoma of maxillary sinus with combined therapy: surgery, radiation, and intra-arterial infusion chemotherapy in Japan. On the other hands, surgery followed by radiation or chemoradiation is the standard option of treatment for sinonasal carcinoma in western countries. This study reports the NCCHE's 14-year experience with maxillary squamous cell cancer, treated with surgical resection followed by radiation, or trimodal combination therapy. Eighty-seven previously untreated, T3-T4 status patients with squamous cell carcinoma of maxillary sinus underwent treatment at our division. During the average follow-up period of 85.9 months, the 5-year overall survival and local control rate were 47.3% and 60%, respectively. The 5-year overall survival among the patients had T3 and T4a tumor were 59.0% and 51.6%. However, all patients with T4b tumor died, their median survival time was 9.1 months. Almost all patients had T3 and T4b were treated with trimodal therapy, a third patient of T4a status underwent treatment with surgery followed by radiation. There was no difference in overall survival according to treatment in T4a patients. We should consider the other approach for treatment, like superselective high-dose cisplatin infusion with concomitant radiotherapy in patients with advanced cancer of maxillary sinus in future.

    This review assessed the effects on chemotherapy induced neutropenia (CIN) of combining oxaliplatin regimens with traditional plant-based medicines (TMs) in the management of colorectal cancer (CRC). 32 RCTs (2224 participants) were included. Meta-analysis showed reduced incidence of grade 3/4 CIN (RR 0.45[0.31, 0.65], I(2)=0%). No studies reported serious adverse events or reduction in tumour response rates associated with concurrent use of oxaliplatin and TM. Due to small sample sizes and risk of bias, these results should be interpreted with caution. Analyses of sub-groups of studies that used similar TM interventions assessed the relative contributions of individual plant-based ingredients to the results. Astragalus, Codonopsis, Atractylodes, Poria and Coix, in various combinations were consistently associated with reduced CIN incidence when administered orally. Experimental studies of these plants have reported reduced myelosuppression and/or enhanced immune response. Further studies of these plants may lead to the development of interventions to supplement conventional CIN treatment. PMID:27497028

  12. Normal tissue toxicity of upper hemibody irradiation (UHBI) when used as a non-cross resistant agent in combination with chemotherapy in the treatment of small cell lung cancer (SCLC)

    International Nuclear Information System (INIS)

    Previous studies at this Institute have investigated the use of HBI as a consolidation agent in the treatment of SCLC. The present Phase I-II study investigates the toxicity and efficacy of UHBI used as a non-cross resistant alternating agent with chemotherapy early in the induction phase of treatment of all stages of SCLC. Toxicity due to the combined effects of chemotherapy plus UHBI is reported as well as effects on bone marrow, lungs and GI tract. The increased incidence of pneumonitis observed in the present study points to a possible interaction of these modalities when HBI is being used as an alternating agent with Cisplatin and Adriamycin

  13. Monitoring by nuclear magnetic resonance imaging in combined radio- and chemotherapy of advanced bladder carcinomas - first results

    International Nuclear Information System (INIS)

    A combination of cis-platinum and radiotherapy was applied in five patients with advanced bladder carcinomas. The patients were examined by nuclear magnetic resonance imaging prior to and following to therapy. Corresponding to cellcinetic considerations regarding tissues with slow cell turnover, a maximum therapy effect is shown about nine months after the end of local therapy. Smaller control intervals are recommended in case of bladder carcinomas with lymph node metastases. Due to the possibility of multiple slice imaging, the nuclear magnetic resonance technique is particularly suited for the monitoring of bladder carcinomas. Sagittal and coronary slices show a better image of tumoral extension at the roof and floor of the bladder than axial computed tomography. Lymph node metastases are represented relatively late by both methods. (orig.)

    Full Text Available Abstract Background Patients with metastatic breast cancer are frequently treated with anthracyclines and taxanes, which are among the most active agents in this disease. Gemcitabine is an interesting candidate for a three-drug combination because of its different mechanism of action and non-overlapping toxicity with respect to the other two drugs. We aimed to evaluate the activity and toxicity of the GAT (gemcitabine, doxorubicin and paclitaxel regimen, derived from experimental preclinical studies, as first-line chemotherapy in patients with stage IIIB-IV breast cancer. Methods Patients with locally advanced or metastatic breast cancer and at least one bidimensionally measurable lesion were included in the present study. Adequate bone marrow reserve, normal cardiac, hepatic and renal function, and an ECOG performance status of 0 to 2 were required. Only prior adjuvant non anthracycline-based chemotherapy was permitted. Treatment consisted of doxorubicin 50 mg/m2 on day 1, paclitaxel 160 mg/m2 on day 2 and gemcitabine 800 mg/m2 on day 6, repeated every 21–28 days. Results Thirty-three consecutive breast cancer patients were enrolled onto the trial (7 stage IIIB and 26 stage IV. All patients were evaluable for toxicity and 29 were assessable for response. A total of 169 cycles were administered, with a median of 6 cycles per patient (range 1–8 cycles. Complete and partial responses were observed in 6.9% and 48.3% of patients, respectively, for an overall response rate of 55.2%.

    2005-05-01

    Full Text Available Review of the role of chemoradiotherapy in the treatment of locally advanced pancreatic cancer with a specific focus on the technical feasibility and the integration of chemoradiotherapy into multimodal treatment concepts. Combined chemoradiotherapy of pancreatic cancer is a safe treatment with an acceptable profile of side effects when applied with modern planning and radiation techniques as well as considering tissue tolerance. Conventionally fractionated radiation regimens with total doses of 45-50 Gy and small-volume boost radiation with 5.4 Gy have found the greatest acceptance. Locoregional lymphatic drainage should be included in the planning of target volumes because the risk of tumor involvement and local or loco-regional recurrence is high. Up to now, 5-fluorouracil has been considered the "standard" agent for concurrent chemoradiotherapy. The role of gemcitabine given concurrently with radiation has not yet been defined, since high local efficacy may also be accompanied by enhanced toxicities. In addition, no dose or administration form has been determined to be "standard" up to now. The focus of presently ongoing research is to define an effective and feasible regimen of concurrent chemoradiotherapy. While preliminary results indicate promising results using gemcitabine-based chemoradiotherapy, reliable data derived from mature phase III trials are greatly needed. Intensity-modulated radiotherapy has been developed to improve target-specific radiation and to reduce organ toxicity. Its clinical relevance still needs to be defined.

Among the isolates resistance to ampicillin (A, chloramphenicol (C, cotrimoxazole (Co and tetracycline (T were plasmid mediated; the plasmid was unstable in S. Typhi, and the other enteric bacteria like Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris were found to be the potential source of dissemination of such plasmids into S. Typhi. The infection with such S. Typhi strains were successfully treated with ciprofloxacin (Cp: MICs 0.0075–0.075 μg mL−1 and/or ofloxacin (Ofx: MICs 0.0125–0.075 μg mL−1, but in the later course, the S. Typhi strains, showing resistance to nalidixic acid, developed low level of resistance to Cp and Ofx, causing the treatment failure. Thus, the treatment regimen was shifted to the third generation cephalosporins like ceftriaxone (Ct and cefotaxime (Cf. Keeping in mind the anticipation of development of resistance to Ct/Cf, we prepared the treatment regimen for MDR enteric fever, based on the double-drug synergy tests in vitro; Cp-gentamycin (FICI 0.121–0.216 and Cp-trimethoprim (FICI 0.14–0.483 combinations were found effective against S.

  2. Three-year disease-free survivors of small cell lung cancer treated with combination chemotherapy with or without chest irradiation

    International Nuclear Information System (INIS)

    One hundred and seventy-four patients with small cell lung cancer (SCLC) treated with combination chemotherapy radiation, were analyzed. Fourteen patients (8%) survived for 3 years or more. Three-year disease-free survival continued for 12 of the 101 patients (12%) with limited disease, and one of 75 (1%) with extensive disease (P<0.05). Patients' sex and performance status were not important in achieving long-term survival. All disease-free survivors, except two who could not be evaluated, achieved a complete response. Although treatment had some influence on long-term survival rates (P<0.05), thoracic radiation did not have significant impact on long-term survival. Three of the 13 patients (23%) developed second malignancies and died; one of these patients also suffered from a progressive neurologic deterioration with dementia. Two other patients died free of SCLC. Eight have remained alive and free of disease. The last relapse was observed at 1.5 years from beginning of treatment. (author)

    2006-05-01

    Full Text Available Abstract Background Bortezomib (Velcade®, a dipeptide boronate proteasome inhibitor, is a novel anti-cancer agent registered for multiple myeloma (MM. It has also shown promising clinical activity in non-small cell lung cancer (NSCLC. Clinical experience with bortezomib so far indicates that overall incidence of cardiac failure associated with bortezomib therapy remains incidental. Nevertheless, acute development or exacerbation of congestive cardiac failure has been associated with bortezomib treatment. Case presentation We present here a case of severe, but reversible, congestive cardiac failure in a lung cancer patient who had no prior cardiac history, after receiving an experimental treatment of bortezomib combined with chemotherapy. Elevated levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP, as retrospectively measured in archived serum samples, were suggestive of pre-existent (sub-clinical left ventricular dysfunction. Conclusion Based on literature, we hypothesize that baseline presence of sub clinical cardiomyopathy, characterized by a dysregulation of the ubiquitin-proteasome system, could have predisposed this patient for a cardiac side effect induced by systemic proteasome inhibition. Patients with heart disease or risk factors for it should be closely monitored when being submitted to treatment with proteasome inhibition therapy such as bortezomib. Caution is therefore warranted in lung cancer patients who often present with cardiac comorbidities.

    Full Text Available Purpose. This retrospective study determined the delayed-type hypersensitivity (DTH skin test and safety of dendritic cell (DC vaccine and cytokine-induced killer (CIK cell immunotherapy and the survival compared to chemotherapy in 239 colorectal cancer (CRC patients. Methods. DTH and safety of the immunotherapy were recorded. The overall survival (OS and disease free survival curves were compared according to the immunotherapy and/or chemotherapy received with Kaplan-Meier estimates. Results. Of the 70 patients who received immunotherapy, 62.86% had a positive DTH skin test, 38.57% developed fever, 47.14% developed insomnia, 38.57% developed anorexia, 4.29% developed joint soreness, and 11.43% developed skin rash. For 204 resectable CRC patients, median survival time (MST (198.00 days was significantly longer in patients with immunotherapy plus chemotherapy than with chemotherapy alone (106.00 days (P=0.02. For 35 patients with unresectable or postsurgery relapsed CRC and who were confirmed to be dead, no statistical difference was observed in the MST between the patients treated with immunotherapy and with chemotherapy (P=0.41. MST in the patients treated with chemotherapy plus immunotherapy was 154 days longer than that of patients treated with chemotherapy alone (P=0.41. Conclusions. DC vaccination and CIK immunotherapy did not cause severe adverse effects, induce immune response against CRC, and prolong OS.

    International Nuclear Information System (INIS)

    39 cases of maxillary sinus cancer were treated with combined intra-arterial infusion of bleomycin and external irradiation of 60Coγ-ray. Serum protein fractions in the sera of 39 cases of maxillary sinus cancer were examined through the radial immunodiffusion method, 1) before radiation treatment was given, 2) at the completion of radiation therapy and 3) after radiation therapy, ranging from 1 month to 36 months. The sera obtained from patients with maxillary sinus cancer before treatment had concentrations of: α1-acid glycoprotein (α1AG), α1-antitrypsin (α1AT), α1-chymotrypsin (α1X), haptoglobin (Hp), ceruloplasmin (Cp), β1C/A glycoprotein (C3), hemopexin (Hx), IgG and of IgA which were elevated compared with those of normal controls: However, the serum concentrations of: prealbumin (Prealb), albumin (Alb), transferrin (Tf), α2-macroglobulin (α2M), HS-glycoprotein (α2HS) and of IgM were reduced significantly. At the completion of radiation therapy, the concentrations of: Prealb, Tf, α1AG, α1X, Hx, C3, IgG, IgA and of IgM rose slightly as compared with levels before radiation therapy, and the concentrations of Alb, of α2HS and of α1AT were reduced. However, there was no significant difference between the former and the latter data. In patients who died within 12 months after treatment, the Prealb, Alb, Tf, α2HS, and IgM levels examined before radiation therapy were reduced and the α1AG level was elevated compared with those who had lived more than 13 months. The Prealb, Alb, Tf, and IgM levels, after radiation therapy were reduced; while the α1AG, Hp, and α1X levels were elevated. In patients who had lived more than 13 months, after treatment, concentrations of Prealb, of Alb, of Tf, of C3, of Hx, of IgG, of IgA and of IgM rose before and after radiation therapy, compared with those who died within 12 months.

    Aim: To investigate the pharmacodynamic and pharmacokinetic parameters of pegylated liposomal doxorubicin (PLD) combined with cyclophosphamide, vincristine, and prednisolone in patients with peripheral T-cell lymphomas (PTCL).Methods: Seven chemonaive patients and four patients with relapsed peripheral T-cell lymphomas were treated with a CCOP regimen consisting of an intravenous administration of cyclophosphamide (750 mg/m2), vincristine (1.4 mg/m2), and PLD (30 mg/m2) on d 1,as well as an oral administration of prednisolone (60 mg/m2)on d 1-5. This regimen was repeated every 3 weeks for six cycles, and the clinical response and toxicity of the regimen were monitored. In addition, the plasma concentration of PLD at different time points was determined before and after treatment. The pharmacokinetics (PKs) software was used to estimate the pharmacokinetic parameters of PLD.Results: The 11 PTCL patients received 35 treatment cycles. Three of them achieved complete response (CR), two partial response (PR), four stable disease (SD), and two progressive disease (PD). The overall response rate (ORR) was 45.5%, and the CR rate was 27.3%. In the 7 chemonaive patients, three achieved CR, two PR, one SD, and one PD. The ORR was 71.4%, and CR rate was 42.9%.The median follow-up time was 15 months, but 6 out of 11 patients were dead at the time of data analysis. The 1-year overall survival rate was 45.5%, and the median progression-free survival (PFS) rate was 6.5 [95% confidence interval (95% Cl) 3.17-19.02] with a survival rate of 11.5 months (95% Cl 6.65-16.36). The main toxicity was myelosuppression. Oral mucositis and hand-foot syndrome 3.56 L/m2, respectively.Conclusion: The CCOP regimen was effective and well tolerated in patients with peripheral T-cell lymphomas. The results of the pharmacokinetic parameters showed that PLD had long retention time in blood circulation.

PTK7 (protein tyrosine kinase 7 belongs to the receptor tyrosine kinase family involved in several physiological, but also malignant, cell behaviors. Recent studies in acute myeloid leukemia have associated PTK7 expression with resistance to anthracycline therapy. PTK7 mRNA expression in primary tumor tissue (PTT and corresponding lymph node tissue (LNT were retrospectively measured in 117 patients with early breast cancer; PTK7 expression was available in 103 PTT and 108 LNT samples. Median age was 60 years (range, 27–87 years. At a median follow-up of 28.5 months, 6 deaths and 16 recurrences had occurred. PTK7 expression correlations with clinicopathological features were computed and PTK7 expression effects on patient outcome were analyzed in three cohorts defined by adjuvant treatment: anthracycline-based treatment, other chemotherapy regimens (including taxane or other substances, or no chemotherapy. Association of PTK7 expression with clinicopathological features was seen only for age in PTT and nodal stage in LNT. High LN PTK7 was associated with poorer disease-free survival (DFS in the total population (3-year

  8. Intensity modulated radiotherapy (IMRT) combined with concurrent but not adjuvant chemotherapy in primary nasopharyngeal cancer – a retrospective single center analysis

    International Nuclear Information System (INIS)

    We report our experience in 49 consecutive patients with nasopharyngeal carcinoma who were treated by Intensity-modulated radiation therapy (IMRT) combined with simultaneous but not adjuvant chemotherapy (CHT). The medical records of 49 patients with histologically proven primary nasopharygeal carcinoma treated with IMRT and concurrent platin-based CHT (predominantly cisplatin weekly) were retrospectively reviewed. The majority of patients showed advanced clinical stages (stage III/IV:72%) with undifferentiated histology (82%). IMRT was performed in step-and-shoot technique using an integrated boost concept in 84%. In this concept, the boost volume covered the primary tumor and involved nodes with doses of 66–70.4 Gy (single dose 2.2 Gy). Uninvolved regional nodal areas were covered with doses of 54–59.4 Gy (median single dose 1.8 Gy). At least one parotid gland was spared. None of the patients received adjuvant CHT. The median follow-up for the entire cohort was 48 months. Radiation therapy was completed without interruption in all patients and 76% of the patients received at least 80% of the scheduled CHT. Four local recurrences have been observed, transferring into 1-, 3-, and 5-year Local Control (LC) rates of 98%, 90% and 90%. One patient developed an isolated regional nodal recurrence, resulting in 1-, 3-, and 5-year Regional Control (RC) rates of 98%. All locoregional failures were located inside the radiation fields. Distant metastases were found in six patients, transferring into 1-, 3, and 5-year Distant Control (DC) rates of 92%, 86% and 86%. Progression free survival (PFS) rates after 1, 3 and 5 years were 86%, 70% and 69% and 1-, 3- and 5-year Overall Survival (OS) rates were 96%, 82% and 79%. Acute toxicity ≥ grade III mainly consisted of dysphagia (32%), leukopenia (24%), stomatitis (16%), infection (8%) and nausea (8%). Severe late toxicity (grade III) was documented in 18% of the patients, mainly as xerostomia (10%). Concurrent chemoradiation

    Background Recent studies have shown that effective ingredients of Chinese herbs are used more and more widely in the treatment or co-treatment of cancers,however,they are usually used separately and there has been limited research about joint application of Chinese herbs in multi-modal treatment.The aim of this study was to screen a QHF(Q:Qingrejiedu,H:Huoxuehuayu and F:Fuzhengguben)formula for effective ingredients from Chinese medicines and assess its anti-hepatic cell cancer(HCC)effect in combination with chemotherapy.Methods Six effective ingredients from Chinese medicine were selected based on the previous literature and used in the study.The QHF formula and the best ratio of ingredients were evaluated in H22 mouse(KM)models with solid tumors and ascites tumors by uniform design and monitoring inhibition of tumor growth and survival.We then observed the anti-hepatic cell cancer(HCC)effect of QHF when combined with cisplatin(DDP)in H22 mouse(Balb/c)models with solid tumors and ascites tumors.Evaluating of the therapeutic effect included the general condition of the mice,inhibition of tumor growth,survival,changes in body weight,thymus index,spleen index and WBC counts.Results The optimal QHF dose ratio for anti-hepatic cell cancer treatment was:800 mg/kg Cinobufotalin,14 mg/kg Ginsenosides Rg3,5.5 mg/kg PNS and 100 mg/kg Lentinan.Treatment was more efficient in inhibiting the growth of transplanted tumors in H22 mice when using the QHF formula(55.91%)than using Cinobufotalin(33.25%),Ginsenosides Rg3(35.11%),PNS(27.12%)or Lentinan(4.97%)separately.QHF also prolonged the life of H22 ascites hepatic cancer mice more efficiently(38.13%)than Cinobufotalin(25.00%),Ginsenosides Rg3(27.27%),PNS(23.30%) or Lentinan (24.43%).QHF combined with DDP could reduce DDP-induced leucopenia,spleen and thymus atrophy and other toxic reactions.Combining QHF with DDP the tumor growth inhibition reached 82.54% with a 66.83% increase in survival.Conclusions QHF is more efficient in

    A glycyrrhetinic acid-modified chitosan-cystamine-poly(ε-caprolactone) copolymer (PCL-SS-CTS-GA) micelle was developed for the co-delivery of doxorubicin (DOX) and curcumin (CCM) to hepatoma cells. Glycyrrhetinic acid (GA) was used as a targeting unit to ensure specific delivery. Co-encapsulation of DOX and CCM was facilitated by the incorporation of poly(ε-caprolactone) (PCL) groups. The highest drug loading content was 19.8% and 8.9% (w/w) for DOX and CCM, respectively. The PCL-SS-CTS-GA micelle presented a spherical or ellipsoidal geometry with a mean diameter of approximately 110nm. The surface charge of the micelle changed from negative to positive, when the pH value of the solution decreased from 7.4 to 6.8. Meanwhile, it also exhibited a character of redox-responsive drug release and GA/pH-mediated endocytosis in vitro. In simulated body fluid with 10mM glutathione, the release rate in 12h was 80.6% and 67.2% for DOX and CCM, respectively. The cell uptake of micelles was significantly higher at pH 6.8 than pH 7.4. The combined administration of DOX and CCM was facilitated by PCL-SS-CTS-GA micelle. Results showed that there was strong synergic effect between the two drugs. The PCL-SS-CTS-GA micelle might turn into a promising and effective carrier for improved combination chemotherapy. PMID:27281238

    Based on the complementary effects of doxorubicin (DOX), all-trans retinoic acid (ATRA) and low molecular weight heparin (LMWH), the combination therapy of DOX, ATRA and LMWH was expected to exert the enhanced anti-tumor effects and reduce the side effects. In this study, amphiphilic LMWH-ATRA conjugate was synthesized for encapsulating the DOX. In this way, DOX, ATRA and LMWH were assembled into a single nano-system by both chemical and physical modes to obtain a novel anti-tumor targeting drug delivery system that can realize the simultaneous delivery of multiple drugs with different properties to the tumor. LMWH-ATRA nanoparticles exhibited good loading capacities for DOX with excellent physico-chemical properties, good biocompatibility, and good differentiation-inducing activity and antiangiogenic activity. The drug-loading capacity was up to 18.7% with an entrapment efficiency of 78.8%. It was also found that DOX-loaded LMWH-ATRA nanoparticles (DHR nanoparticles) could be efficiently taken up by tumor cells via endocytic pathway, and mainly distributed in cytoplasm at first, then transferred into cell nucleus. Cell viability assays suggested that DHR nanoparticles maintained the cytotoxicity effect of DOX on MCF-7 cells. Moreover, the in vivo imaging analysis indicated that DiR-loaded LMWH-ATRA nanoparticles could target the tumor more effectively as compared to free DiR. Furthermore, DHR nanoparticles possessed much higher anticancer activity and reduced side effects compared to free drugs solution. These results suggested that DHR nanoparticles could be considered as a promising targeted delivery system for combination cancer chemotherapy with lower adverse effects.

    To explore the potential complementary value of PET/CT and dynamic contrast-enhanced MRI in predicting pathological response to neoadjuvant chemotherapy (NAC) of breast cancer and the dependency on breast cancer subtype. We performed {sup 18}F-FDG PET/CT and MRI examinations before and during NAC. The imaging features evaluated on both examinations included baseline and changes in {sup 18}F-FDG maximum standardized uptake value (SUVmax) on PET/CT, and tumour morphology and contrast uptake kinetics on MRI. The outcome measure was a (near) pathological complete response ((near-)pCR) after surgery. Receiver operating characteristic curves with area under the curve (AUC) were used to evaluate the relationships between patient, tumour and imaging characteristics and tumour responses. Of 93 patients, 43 achieved a (near-)pCR. The responses varied among the different breast cancer subtypes. On univariate analysis the following variables were significantly associated with (near-)pCR: age (p = 0.033), breast cancer subtype (p < 0.001), relative change in SUVmax on PET/CT (p < 0.001) and relative change in largest tumour diameter on MRI (p < 0.001). The AUC for the relative reduction in SUVmax on PET/CT was 0.78 (95 % CI 0.68-0.88), and for the relative reduction in tumour diameter at late enhancement on MRI was 0.79 (95 % CI 0.70-0.89). The AUC increased to 0.90 (95 % CI 0.83-0.96) in the final multivariate model with PET/CT, MRI and breast cancer subtype combined (p = 0.012). PET/CT and MRI showed comparable value for monitoring response during NAC. Combined use of PET/CT and MRI had complementary potential. Research with more patients is required to further elucidate the dependency on breast cancer subtype. (orig.)

  15. Comparison of Intrahepatic and Pancreatic Perfusion on Fusion Images Using a Combined SPECT/CT System and Assessment of Efficacy of Combined Continuous Arterial Infusion and Systemic Chemotherapy in Advanced Pancreatic Carcinoma

    International Nuclear Information System (INIS)

    Purpose. The purpose of this study was to compare intrahepatic and pancreatic perfusion on fusion images using a combined single-photon emission computed tomography (SPECT)/CT system and to evaluate the efficacy of combined continuous transcatheter arterial infusion (CTAI) and systemic chemotherapy in the treatment of advanced pancreatic carcinoma. Materials and Methods. CTAI was performed in 33 patients (22 men, 11 women; age range, 35-77 years; mean age, 60 years) with stage IV pancreatic cancer with liver metastasis. The reservoir was transcutaneously implanted with the help of angiography. The systemic administration of gemcitabine was combined with the infusion of 5-fluorouracil via the reservoir. In all patients we obtained fusion images using a combined SPECT/CT system. Pancreatic perfusion on fusion images was classified as perfusion presence or as perfusion absent in the pancreatic cancer. Using WHO criteria we recorded the tumor response after 3 months on multislice helical CT scans. Treatment effects were evaluated based on the pancreatic cancer, liver metastasis, and factors such as intrahepatic and pancreatic perfusion on fusion images. For statistical analysis we used the chi-square test; survival was evaluated by the Kaplan Meier method (log-rank test). Results. On fusion images, pancreatic and intrahepatic perfusion was recorded as hot spot and as homogeneous distribution, respectively, in 18 patients (55%) and as cold spot and heterogeneous distribution, respectively, in 15 (45%). Patients with hot spot in the pancreatic tumor and homogeneous distribution in the liver manifested better treatment results (p < 0.05 and p < 0.01, respectively). Patients with hot spot both in the pancreatic cancer and in the liver survived longer than those with cold spot in the pancreatic cancer and heterogeneous distribution in the liver (median ± SD, 16.0 ± 3.7 vs. 8.0 ± 1.4 months; p < 0.05). Conclusions. We conclude that in patients with advanced pancreatic

    Metastatic gastric cancer remains a non-curative disease.Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase Ⅱ and Ⅲ studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed.Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase Ⅲ trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116study, postoperative chemoradiation has been Accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease.Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase Ⅱstudies are showing promising results. Phase Ⅲ trials are needed.

  20. 3D Radiotherapy Can Be Safely Combined With Sandwich Systemic Gemcitabine Chemotherapy in the Management of Pancreatic Cancer: Factors Influencing Outcome

    International Nuclear Information System (INIS)

    Purpose: The aim of this Phase II study was to examine whether concurrent continuous infusion 5-fluorouracil (CI 5FU) plus three-dimensional conformal planning radiotherapy sandwiched between gemcitabine chemotherapy is effective, tolerable, and safe in the management of pancreatic cancer. Methods and Materials: Patients were enrolled in two strata: (1) resected pancreatic cancer at high risk of local relapse (postsurgery arm, n = 22) or (2) inoperable pancreatic cancer in head or body without metastases (locally advanced arm, n = 41). Gemcitabine was given at 1,000 mg/m2 weekly for 3 weeks followed by 1 week rest then 5-6 weeks of radiotherapy and concurrent CI 5FU (200 mg/m2/day). After 4 weeks' rest, gemcitabine treatment was reinitiated for 12 weeks. Results: For the two arms combined, treatment-related Grade 3 and 4 toxicities were reported by 25 (39.7%) and 7 (11.1%) patients, respectively. No significant late renal or hepatic toxicity was observed. In the postsurgery arm (R1 54.5%), median time to progressive disease from surgery was 11.0 months, median time to failure of local control was 32.9 months, and median survival time was 15.6 months. The 1- and 2-year survival rates were 63.6% and 31.8%. No significant associations between outcome and mutations in K-ras or TP53 or microsatellite instability were identified. Post hoc investigation of cancer antigen 19-9 levels found baseline levels and increases postbaseline were associated with shorter survival (p = 0.0061 and p < 0.0001, respectively). Conclusions: This three-dimensional chemoradiotherapy regimen is safe and promising, with encouraging local control for a substantial proportion of patients, and merits testing in a randomized trial

  1. Intensity-Modulated Radiotherapy Might Increase Pneumonitis Risk Relative to Three-Dimensional Conformal Radiotherapy in Patients Receiving Combined Chemotherapy and Radiotherapy: A Modeling Study of Dose Dumping

    International Nuclear Information System (INIS)

    Purpose: To model the possible interaction between cytotoxic chemotherapy and the radiation dose distribution with respect to the risk of radiation pneumonitis. Methods and Materials: A total of 18 non-small-cell lung cancer patients previously treated with helical tomotherapy at the University of Wisconsin were selected for the present modeling study. Three treatment plans were considered: the delivered tomotherapy plans; a three-dimensional conformal radiotherapy (3D-CRT) plan; and a fixed-field intensity-modulated radiotherapy (IMRT) plan. The IMRT and 3D-CRT plans were generated specifically for the present study. The plans were optimized without adjusting for the chemotherapy effect. The effect of chemotherapy was modeled as an independent cell killing process by considering a uniform chemotherapy equivalent radiation dose added to all voxels of the organ at risk. The risk of radiation pneumonitis was estimated for all plans using the Lyman and the critical volume models. Results: For radiotherapy alone, the critical volume model predicts that the two IMRT plans are associated with a lower risk of radiation pneumonitis than the 3D-CRT plan. However, when the chemotherapy equivalent radiation dose exceeds a certain threshold, the radiation pneumonitis risk after IMRT is greater than after 3D-CRT. This threshold dose is in the range estimated from clinical chemoradiotherapy data sets. Conclusions: Cytotoxic chemotherapy might affect the relative merit of competing radiotherapy plans. More work is needed to improve our understanding of the interaction between chemotherapy and the radiation dose distribution in clinical settings.

  2. Usefulness of combined metabolic volumetric indices of 18FFDG PET/CT for the early prediction of neoadjuvant chemotherapy outcomes in breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the usefulness of metabolic volumetric indices of 18F fluorodeoxy D glucose (18FFDG) positron emission tomography/computed tomography (PET/CT) for the evaluation of neoadjuvant chemotherapy outcomes in breast cancer. Twenty four patients with locally advanced breast cancer were enrolled in the study. They underwent baseline 18F FDG PET/CT scan and received four or six cycles of neoadjuvant chemotherapy, interim 18F FDG PET/CT was done after second cycle of chemotherapy. Maximum standardized uptake value (SUVmax), metabolic tumor volume(MTV), and total lesion glycolysis (TLG) of the primary lesions were calculated. Reduction rates of these parameters were obtained between baseline and interim 18F FDG PET/CT. Chemotherapy outcomes were assessed using tumor size reduction rate and histological grading system (Miller and Payne system). Reduction rates of SUVmax, MTV, and TLG correlated with chemotherapy outcomes. MTV and TLG reduction rates showed significant correlation with tumor size reduction rate (R=0.68, P=0.0004; R=0.62, P=0.002, respectively). However, SUVmax reduction rate showed no significant correlation. MTV and TLG reduction rates were significantly higher in responders than nonresponders, as determined by Miller and Payne system (P<0.0007, P<0.0002). However, SUVmax reduction rate showed no significant difference. On ROC analysis, the area under the MTV and TLG curves was 0.886, and that of SUVmax was 0.743. Sensitivity, specificity, positive predictive value, and negative predictive value to predict histopathologic response were the same for MTV and TLG, and the values were 100%, 85,7%, 83.3%, and 100%, respectively (at the reduction rate of 93.2%, for MTV, and 95.8% for TLG). Changes of metabolic volumetric indices successfully reflected the neoadjuvant chemotherapy outcomes. MTV and TLG could be robust indices in discriminating pathologic responder as SUVmax, after neoadjuvant chemotherapy

  3. Treating gastrointestinal cancer by intervention, intraperitoneal hyperthermic perfusion chemotherapy, intravenous micro-pump chemotherapy

    International Nuclear Information System (INIS)

    157 cases of gastrointestinal cancer patients after resection were randomly divided into treated group and control group. The treated group (intraperitoneal hyperthermic perfusion chemotherapy combined with postoperative continuous intraarterial infusion and intravenous micro-pump chemotherapy) consisted of 72 cases, the control group (Intravenous chemotherapy), 85 cases. The peritoneal and hepatic metastasis rates and 3 a survival rate were studied. The intraperitoneal hyperthermic perfusion chemotherapy combined with the postoperative continuous intraarterial infusion and intravenous micro-pump chemotherapy is an effective way to control the recurrence on the peritoneal and hepatic metastasis of advanced gastrointestinal neoplasms after operation.

    In pre-clinical models, the only two chemotherapy drugs which have been demonstrated to directly reduce the number of myeloid-derived suppressor cells (MDSCs) are gemcitabine and 5-fluorouracil. Here we analyze the dynamics of MDSCs, phenotyped as Lin-DR-CD11b+, in patients with advanced pancreatic cancer receiving the combination of gemcitabine and capecitabine, a 5-FU pro-drug. We found no evidence that gemcitabine and capecitabine directly reduce MDSC% in patients. Gemcitabine and capecita...

  6. A meta-analysis of hyperfractionated and accelerated radiotherapy and combined chemotherapy and radiotherapy regimens in unresected locally advanced squamous cell carcinoma of the head and neck

    International Nuclear Information System (INIS)

    Former meta-analyses have shown a survival benefit for the addition of chemotherapy (CHX) to radiotherapy (RT) and to some extent also for the use of hyperfractionated radiation therapy (HFRT) and accelerated radiation therapy (AFRT) in locally advanced squamous cell carcinoma (SCC) of the head and neck. However, the publication of new studies and the fact that many older studies that were included in these former meta-analyses used obsolete radiation doses, CHX schedules or study designs prompted us to carry out a new analysis using strict inclusion criteria. Randomised trials testing curatively intended RT (≥60 Gy in >4 weeks/>50 Gy in <4 weeks) on SCC of the oral cavity, oropharynx, hypopharynx, and larynx published as full paper or in abstract form between 1975 and 2003 were eligible. Trials comparing RT alone with concurrent or alternating chemoradiation (5-fluorouracil (5-FU), cisplatin, carboplatin, mitomycin C) were analyzed according to the employed radiation schedule and the used CHX regimen. Studies comparing conventionally fractionated radiotherapy (CFRT) with either HFRT or AFRT without CHX were separately examined. End point of the meta-analysis was overall survival. Thirty-two trials with a total of 10 225 patients were included into the meta-analysis. An overall survival benefit of 12.0 months was observed for the addition of simultaneous CHX to either CFRT or HFRT/AFRT (p < 0.001). Separate analyses by cytostatic drug indicate a prolongation of survival of 24.0 months, 16.8 months, 6.7 months, and 4.0 months, respectively, for the simultaneous administration of 5-FU, cisplatin-based, carboplatin-based, and mitomycin C-based CHX to RT (each p < 0.01). Whereas no significant gain in overall survival was observed for AFRT in comparison to CFRT, a substantial prolongation of median survival (14.2 months, p < 0.001) was seen for HFRT compared to CFRT (both without CHX). RT combined with simultaneous 5-FU, cisplatin, carboplatin, and mitomycin C as

  7. Accelerated high-dose radiotherapy alone or combined with either concomitant or sequential chemotherapy; treatments of choice in patients with Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Results of high-dose chemo-radiotherapy (CRT), using the treatment schedules of EORTC study 08972/22973 or radiotherapy (RT) alone were analyzed among all patients (pts) with Non Small Cell Lung Cancer (NSCLC) treated with curative intent in our department from 1995–2004. Included are 131 pts with medically inoperable or with irresectable NSCLC (TNM stage I:15 pts, IIB:15 pts, IIIA:57 pts, IIIB:43 pts, X:1 pt). Group I: Concomitant CRT: 66 Gy/2.75 Gy/24 fractions (fx)/33 days combined with daily administration of cisplatin 6 mg/m2: 56 pts (standard). Group II: Sequential CRT: two courses of a 21-day schedule of chemotherapy (gemcitabin 1250 mg/m2 d1, cisplatin 75 mg/m2 d2) followed by 66 Gy/2.75 Gy/24 fx/33 days without daily cisplatin: 26 pts. Group III: RT: 66 Gy/2.75 Gy/24 fx/33 days or 60 Gy/3 Gy/20 fx/26 days: 49 pts. The 1, 2, and 5 year actuarial overall survival (OS) were 46%, 24%, and 15%, respectively. At multivariate analysis the only factor with a significantly positive influence on OS was treatment with chemo-radiation (P = 0.024) (1-, 2-, and 5-yr OS 56%, 30% and 22% respectively). The incidence of local recurrence was 36%, the incidence of distant metastases 46%. Late complications grade 3 were seen in 21 pts and grade 4 in 4 patients. One patient had a lethal complication (oesophageal). For 32 patients insufficient data were available to assess late complications. In this study we were able to reproduce the results of EORTC trial 08972/22973 in a non-selected patient population outside of the setting of a randomised trial. Radiotherapy (66 Gy/24 fx/33 days) combined with either concomitant daily low dose cisplatin or with two neo-adjuvant courses of gemcitabin and cisplatin are effective treatments for patients with locally advanced Non-Small Cell Lung Cancer. The concomitant schedule is also suitable for elderly people with co-morbidity

  8. Accelerated hyperfractionated radiotherapy combined with induction and concomitant chemotherapy for inoperable non-small-cell lung cancer. Impact of total treatment time

    International Nuclear Information System (INIS)

    Tumour cell proliferation during conventionally fractionated radiotherapy (RT) can negatively influence the treatment outcome in patients with unresectable non-small-cell lung cancer (NSCLC). Accelerated and hyperfractionated RT may therefore have an advantage over conventional RT. Moreover, earlier studies have suggested improved survival with addition of cisplatin-based chemotherapy (CT). We present here the results of combined treatment with induction and concomitant CT and accelerated hyperfractionated RT in a retrospective series of patients with advanced NSCLS. Between August 1990 and August 1995, 90 consecutive patients, aged 42-77 years (median 63 years), with locally advanced unresectable or medically inoperable NSCLC and good performance status were referred for treatment: stage: I 23%, IIIa 37%, IIIb 40%. Patient histologies included: squamous cell carcinoma 52%, adenocarcinoma 34% and large cell carcinoma 13%. The treatment consisted of two courses of CT (cisplatin 100 mg/m2 day 1 and etoposide 100 mg/m2 day 1-3 i.v.), the second course given concomitantly with RT. The total RT dose was 61.2-64.6 Gy, with two daily fractions of 1.7 Gy. A one-week interval was introduced after 40.8 Gy to reduce acute toxicity, making the total treatment time 4.5 weeks. Concerning toxicity, 33 patients had febrile neutropenia, 10 patients suffered from grade III oesophagitis and 7 patients had grade III pneumonitis. There were two possible treatment-related deaths, one due to myocardial infarction and the other due to a pneumocystis carinii infection. The 1-, 2- and 3-year overall survival rates were 72%, 46% and 34%, respectively; median survival was 21.3 months. Fifty-nine patients had progressive disease: 21 failed locoregionally, 29 had distant metastases and 9 patients had a combination of these. Pretreatment weight loss was the only prognostic factor found, except for stage. However, the results for stage IIIb were no different from those for stage IIIa. We conclude

    Full Text Available Abstract Background Long-term locoregional control in locally advanced squamous cell carcinoma of the head and neck (SCCHN remains challenging. While recent years have seen various approaches to improve outcome by intensification of treatment schedules through introduction of novel induction and combination chemotherapy regimen and altered fractionation regimen, patient tolerance to higher treatment intensities is limited by accompanying side-effects. Combined radioimmunotherapy with cetuximab as well as modern radiotherapy techniques such as intensity-modulated radiotherapy (IMRT and carbon ion therapy (C12 are able to limit toxicity while maintaining treatment effects. In order to achieve maximum efficacy with yet acceptable toxicity, this sequential phase II trial combines induction chemotherapy with docetaxel, cisplatin, and 5-FU (TPF followed by radioimmunotherapy with cetuximab as IMRT plus carbon ion boost. We expect this approach to result in increased cure rates with yet manageable accompanying toxicity. Methods/design The TPF-C-HIT trial is a prospective, mono-centric, open-label, non-randomized phase II trial evaluating efficacy and toxicity of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 50 patients with histologically proven locally advanced SCCHN following TPF induction chemotherapy. Patients receive 24 GyE carbon ions (8 fractions and 50 Gy IMRT (2.0 Gy/fraction in combination with weekly cetuximab throughout radiotherapy. Primary endpoint is locoregional control at 12 months, secondary endpoints are disease-free survival, progression-free survival, overall survival, acute and late radiation effects as well as any adverse events of the treatment as well as quality of life (QoL analyses. Discussion The primary objective of TPF-C-HIT is to evaluate efficacy and toxicity of cetuximab in combination with combined IMRT/carbon ion therapy following TPF induction in locally advanced SCCHN.

    Advanced-stage cancer patients often suffer from anemia that closely resembles the anemia of chronic inflammatory diseases characterized by specific changes in iron homeostasis and absorption. i.v. iron improves the efficacy of recombinant human erythropoietin (rHuEPO) in anemic cancer patients undergoing chemotherapy. We report the results of an open-label, randomized, prospective trial aimed at testing the efficacy and safety of treatment with oral lactoferrin versus i.v. iron, both combined with rHuEPO, for the treatment of anemia in a population of 148 advanced cancer patients undergoing chemotherapy. All patients received s.c. rHuEPO-β, 30,000 UI once weekly for 12 weeks, and were randomly assigned to ferric gluconate (125 mg i.v. weekly) or lactoferrin (200 mg/day). Both arms showed a significant hemoglobin increase. No difference in the mean hemoglobin increase or the hematopoietic response, time to hematopoietic response, or mean change in serum iron, C-reactive protein, or erythrocyte sedimentation rate were observed between arms. In contrast, ferritin decreased in the lactoferrin arm whereas it increased in the i.v. iron arm. In conclusion, these results show similar efficacy for oral lactoferrin and for i.v. iron, combined with rHuEPO, for the treatment of anemia in advanced cancer patients undergoing chemotherapy.

    Full Text Available A 67-year-old woman with debilitation and massive ascites was admitted to our hospital and diagnosed with stage IV scirrhous gastric cancer with peritoneal dissemination. After successful nasojejunal tube feeding because of oral intake disability, TS-1 combined with paclitaxel chemotherapy was selected. TS-1 at 80mg/m2 was given daily via nasojejunal tube for 2 weeks, followed by a 1-week rest, and paclitaxel at 50mg/m2 was administered intravenously on day 1 and 8. There were no serious side effects. After 4 cycles, a partial response was observed and percutaneous transesophageal gastro-tubing (PTEG was placed. After the fifth cycle, she was transferred to her home and received chemotherapy in an outpatient clinic. After 7 cycles, the disease progressed, and TS-1 combined with low-dose cisplatin was administered for 3 cycles. However, the patient died 16 weeks after discharge. PTEG was useful not only for a route of TS-1 administration, but also for receiving chemotherapy at home to maintain her quality.

    Full Text Available Objectives. To test the efficiency and safety of sequential application of retinoic acid (ATRA, Realgar-Indigo naturalis formula (RIF and chemotherapy (CT were used as the maintenance treatment in patients with acute promyelocytic leukemia (APL. Methods. This was a retrospective study of 98 patients with newly diagnosed APL who accepted two different maintenance treatments. After remission induction and consolidation chemotherapy according to their Sanz scores, patients received two different kinds of maintenance scheme. The first regimen was using ATRA, RIF, and standard dose of CT sequentially (ATRA/RIF/CT regimen, while the second one was using ATRA and low dose of chemotherapy with methotrexate (MTX plus 6-mercaptopurine (6-MP alternately (ATRA/CTlow regimen. The OS, DFS, relapse rate, minimal residual disease, and adverse reactions in two groups were monitored and evaluated. Results. ATRA/RIF/CT regimen could effectively reduce the chance of relapse in different risk stratification of patients, but there was no significant difference in 5-year DFS rate and OS rate between the two groups. Besides, the patients in the experimental group suffered less severe adverse reactions than those in the control group. Conclusions. The repeated sequential therapeutic regimen to APL with ATRA, RIF, and chemotherapy is worth popularizing for its high effectiveness and low toxicity.

  18. Combined breast conserving surgery, chemotherapy, and irradiation in breast cancer treatment. Role of the interval between surgery and onset of radiotherapy

    International Nuclear Information System (INIS)

    Background: The timing of breast conserving surgery, chemotherapy, and radiotherapy in breast cancer treatment has become the subject of increasing interest over the last years. Results: Five years after start of treatment overall survival, disease-free survival, and local recurrence rates were 86% (95%-confidence limits, 76 to 93%), 73% (61 to 83%), and 8% (3 to 16%), respectively (totally 72 patients). For disease-free survival, the only significant prognostic factor was the number of involved lymph nodes: 0 to 3=86%, ≥4=40% (p20 weeks) had no significant influence on disease-free survival or local tumor control. In contrast, there was a trend of increased regional and distant failure with shortening of the interval due to the delivery of less than 6 cycles chemotherapy before the onset of radiotherapy. Conclusions: In our experience, there was no negative impact of a delay of radiotherapy in order to deliver full course chemotherapy before initiation of radiotherapy. However, the low statistical power of this analysis due to the small number of patients must be considered. It appears possible that a less intense chemotherapy before starting radiation treatment correlates with enhanced distant failure and subsequently decreased disease-free survival rates. Therefore, for patients at increased risk for distant metastasis, we prefer to give 6 cycles polychemotherapy before irradiation. (orig./VHE)

    Purpose: Radiation Therapy Oncology Group 0417 was a phase II study that explored the safety and efficacy of the addition of bevacizumab to chemoradiation therapy. The safety results have been previously reported. Herein we report the secondary efficacy endpoints of overall survival (OS), locoregional failure (LRF), para-aortic nodal failure (PAF), distant failure (DF), and disease-free survival (DFS). Methods and Materials: Eligible patients with bulky Stage IB-IIIB disease were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiation therapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for 3 cycles during chemoradiation. For OS, failure was defined as death of any cause and was measured from study entry to date of death. LRF was defined as any failure in the pelvis. PAF was defined as any para-aortic nodal failure. DF was analyzed both including and excluding PAF. DFS was measured from study entry to date of first LRF. DF was measured with or without PAF or death. OS and DFS were estimated by the Kaplan-Meier method, and LRF and DF rates were estimated by the cumulative incidence method. Results: 49 eligible patients from 28 institutions were enrolled between 2006 and 2009. The median follow-up time was 3.8 years (range, 0.8-6.0 years). The surviving patients had a median follow-up time of 3.9 years (range, 2.1-6.0 years). Most patients had tumors of International Federation of Gynecology and Obstetrics Stage IIB (63%), and 80% were squamous. The 3-year OS, DFS, and LRF were 81.3% (95% confidence interval [CI], 67.2%-89.8%), 68.7% (95% CI, 53.5%-79.8%), and 23.2% (95% CI, 11%-35.4%), respectively. The PAF, DF without PAF, and DF with PAF at 3 years were 8.4% (95% CI, 0.4%-16.3%), 14.7% (95% CI, 4.5%-24.9%), and 23.1% (95% CI 11.0%-35.2%), respectively. Conclusion: In this study, bevacizumab in combination with standard pelvic chemoradiation therapy for locally advanced cervical

  20. Effectiveness of evaluating tumor vascularization using 3D power Doppler ultrasound with high-definition flow technology in the prediction of the response to neoadjuvant chemotherapy for T2 breast cancer: a preliminary report

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the effectiveness of advanced ultrasound (US) imaging of vascular flow and morphological features in the prediction of a pathologic complete response (pCR) and a partial response (PR) to neoadjuvant chemotherapy for T2 breast cancer.Twenty-nine consecutive patients with T2 breast cancer treated with six courses of anthracycline-based neoadjuvant chemotherapy were enrolled. Three-dimensional (3D) power Doppler US with high-definition flow (HDF) technology was used to investigate the blood flow in and morphological features of the tumors. Six vascularity quantization features, three morphological features, and two vascular direction features were selected and extracted from the US images. A support vector machine was used to evaluate the changes in vascularity after neoadjuvant chemotherapy, and pCR and PR were predicted on the basis of these changes.The most accurate prediction of pCR was achieved after the first chemotherapy cycle, with an accuracy of 93.1% and a specificity of 85.5%, while that of a PR was achieved after the second cycle, with an accuracy of 79.31% and a specificity of 72.22%.Vascularity data can be useful to predict the effects of neoadjuvant chemotherapy. Determination of changes in vascularity after neoadjuvant chemotherapy using 3D power Doppler US with HDF can generate accurate predictions of the patient response, facilitating early decision-making.

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

    International Nuclear Information System (INIS)

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

  3. Adjuvant chemotherapy and cancer cure

    International Nuclear Information System (INIS)

    The use of chemotherapy as an adjuvant to surgery and/or radiotherapy is well founded in experimental tumor systems and appears to be effective in patients in some circumstances. It is clear from both clinical and experimental studies that (1) the dose is important, (2) the earlier chemotherapy is started after primary therapy the better, and (3) combination chemotherapy may be more effective than single-agent treatment. The better the estimation of risk of recurrence, the better the assessment of the risk-benefit ratio with adjuvant therapy. Salvage therapy as well as relative risk of recurrence are considerations in the choice of patients to be treated. Finally, some evidence is presented to indicate that alkylating agents may not be necessary in combination regimens for adjuvant therapy if effective antimetabolite combinations are available

    Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

  5. Adjuvant chemotherapy of pT1a and pT1b breast carcinoma: results from the NEMESI study

    International Nuclear Information System (INIS)

    The prognosis of pT1a-pT1b breast cancer (BC) used to be considered very good, with a 10-y RFS of 90%. However, some retrospective studies reported a 10-y RFS of 81%–86% and suggested benefit from adjuvant systemic therapy. To evaluate the variables that determined the choice of adjuvant chemotherapy and the type of chemotherapy delivered in pT1a-pT1b BC, we analysed the small tumours enrolled in the NEMESI study. Out of 1,894 patients with pathological stage I-II BC enrolled in NEMESI, 402 (21.2%) were pT1a-pT1b. Adjuvant chemotherapy was delivered in 127/402 (31.59%). Younger age, grading G3, high proliferative index, ER-negative and HER2-positive status were significantly associated with the decision to administer adjuvant chemotherapy. An anthracycline without taxane regimen was administered in 59.1% of patients, anthracycline with taxane in 24.4%, a CMF-like regimen in 14.2% and taxane in 2.4%. Adjuvant chemotherapy was administered in 88.4% triple-negative and 73.46% HER2-positive pT1a-pT1b BC. Adjuvant trastuzumab was delivered in 30/49 HER2-positive BC (61.2%). Adjuvant chemotherapy was delivered in 31.59% T1a-pT1b BC treated at 63 Italian oncological centres from January 2008 to June 2008. The choice to deliver chemotherapy was based on biological prognostic factors. Anthracycline-based chemotherapy was administered in 83.5% patients

  6. Increased incidence of myelodysplastic syndrome and acute myeloid leukemia following breast cancer treatment with radiation alone or combined with chemotherapy: a registry cohort analysis 1990-2005

    International Nuclear Information System (INIS)

    Our objective was to measure myelodysplastic syndrome (MDS) and acute myelogenous leukemia (AML) risk associated with radiation and/or chemotherapy breast cancer (BC) treatment. Our study cohort was composed of BC patients diagnosed from 1990 to 2005 and followed up for blood disorders, mean length of follow up = 7.17 years, range 2-18 years. 5790 TNM stage 0-III patients treated with surgery alone, radiation and/or chemotherapy were included. Patients without surgery (n = 111), with stem cell transplantation (n = 98), unknown or non-standard chemotherapy regimens (n = 94), lost to follow up (n = 66) or 'cancer status unknown' (n = 67) were excluded. Rates observed at our community based cancer care institution were compared to SEER incidence data for rate ratio (RR) calculations. 17 cases of MDS/AML (10 MDS/7 AML) occurred during the follow up period, crude rate .29% (95% CI = .17, .47), SEER comparison RR = 3.94 (95% CI = 2.34, 6.15). The RR of MDS in patients age < 65 comparing our cohort incidence to SEER incidence data was 10.88 (95% CI = 3.84, 24.03) and the RR of AML in patients age < 65 was 5.32 (95% CI = 1.31, 14.04). No significant increased risk of MDS or AML was observed in women ≥ 65 or the surgery/chemotherapy-only group. A RR of 3.32 (95% CI = 1.42, 6.45) was observed in the surgery/radiation-only group and a RR of 6.32 (95% CI = 3.03, 11.45) in the surgery/radiation/chemotherapy group. 3 out of 10 MDS cases died of disease at an average 3.8 months post diagnosis and five of seven AML cases died at an average 9 months post diagnosis. An elevated rate of MDS and AML was observed among breast cancer patients < 65, those treated with radiation and those treated with radiation and chemotherapy compared to available population incidence data. Although a small number of patients are affected, leukemia risk associated with treatment and younger age is significant

    Background Oxidative stress genes are related to cancer development and treatment response. In this study, we aimed to determine the predictive and prognostic roles of oxidative stress-related genetic polymorphisms in metastatic gastric cancer (MGC) patients treated with chemotherapy. Methods In this retrospective study, we genotyped nine oxidative stress-related single nucleotide polymorphisms (SNPs) in NQO1, SOD2, SOD3, PON1, GSTP1, GSTT1, and NOS3 (rs1800566, rs10517, rs4880, rs1799895, rs662, rs854560, rs1695, rs2266637, rs1799983, respectively) in 108 consecutive MGC patients treated with epirubicin, oxaliplatin, and 5-fluorouracil (EOF) regimen as the first-line chemotherapy and analyzed the association between the genotypes and the disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). Results We found that, in addition to a lower pathological grade (p = 0.017), NQO1 rs1800566 CT/TT genotype was an independent predictive factor of poor PFS (hazard ratio [HR] = 1.97, 95% confidence interval [CI] = 1.23–3.16; p = 0.005). PON1 rs662 AA/AG genotype was significantly associated with poor OS (HR = 1.95, 95% CI = 1.07–3.54; p = 0.029). No associations were detected between the nine SNPs and DCR. Conclusions NQO1 rs1800566 is an independent predictive factor of PFS for MGC patients treated with EOF chemotherapy, and PON1 rs662 is a noteworthy prognostic factor of OS. Information on oxidative stress-related genetic variants may facilitate optimization of individualized chemotherapy in clinical practice. PMID:25545243

    Full Text Available Background and objective Chemotherapy is a highly efficient primary treatment for extensive-stage small cell lung cancer (ES-SCLC. However, patients receiving such treatment are prone to develop drug resistance. Local treatment is palliative and thus can alleviate the local symptoms and improve quality of life, but limited evidence is available for prolonging survival. Hence, this study evaluated the role of local treatment in chemotherapy of patients with ES-SCLC. Methods A total of 302 ES-SCLC cases were enrolled in this retrospective study. Prognostic factors were analyzed by Kaplan-Meier and Cox multivariate proportional hazards model. Results Median progression-free survival (PFS and median survival time (MST of the patients were 4.4 and 10.4 months, respectively. 1-, 2-, and 3-year survival rates were 37.8%, 10.2% and 4.4%, correspondingly. The MST of the primary tumor radiotherapy plus chemotherapy group was 14.3 months, whereas that of the chemotherapy group was 8.2 months (P<0.01. The MSTs of multiple-site, single-site, and non-metastasis local treatments were 18.7, 12.3 and 8.9 months, respectively (P<0.01. The MSTs of initiative, passive, and non-metastasis local treatments were 16.0, 10.9 and 9.4 months, correspondingly (P<0.01. The MSTs of patients with prophylactic cranial irradiation (PCI and those without PCI were 19.8 and 9.9 months, respectively (P<0.01. Primary tumor radiotherapy, metastasis local treatment, and PCI were independent prognostic factors for ES-SCLC. Conclusion Primary tumor radiotherapy, metastasis local treatment, and PCI can significantly improve survival in patients with ES-SCLC.

    Objective: To evaluate the activity and safety of combination chemotherapy with gemcitabine plus oxaliplatin (GEMOX regimen) in patients of advanced pancreatic carcinoma. Methods: 30 patients with advanced pancreatic cancer were enrolled into this study. All patients received gemcitabine 1000 mg/m2, given by 30-minute intravenous infusion, on days 1 and 8 of each 21-day cycle. Oxaliplatin 100 mg/m2 was administered as a 2 h infusion on day 1 of each 21 day. Clinical outcomes for patients treated with two cycles of chemotherapy were evaluated according to WHO criteria. Results: All 30patients were eligible for effectiveness and safety analysis. Objective response rate was approximately 20.0%. Clinical benefit response (CBR) was a composite of assessment of pain, performance status and body weight. The pain relief rate, improvement rate of performance status and body weight were 53.3%, 46.7% and 36.7%, respectively. The main adverse effects were bone marrow depression, peripheral nerve toxicity and gastrointestinal reaction. There was no treatment-related death during the chemotherapy. Conclusion: The high response rate with low toxicity observed in this study suggests that GEMOX regimen may be an effective alternative curative treatment for patients with advanced pancreatic carcinoma and can be used more extensively in clinical practice.

    Objective: To evaluate the efficacy and safety of celecoxib plus platinum-doublet as first-line chemotherapy in treatment of advanced non-small cell lung cancer (NSCLC), and to determine the subgroup benefiting from celecoxib combined therapy by molecular analysis. Methods: A total of 44 treatment-naive patients of advanced NSCLC with positive cyclooxygenase-2 (COX-2) expression confirmed by immunohistochemical (IHC) staining were designed to receive celecoxib plus platinum-doublet chemotherapy (cisplatin plus gemcitabine, novelbine or docetaxol) from February 2005 to May 2007. On 5(7 day before chemotherapy, 400 mg celecoxib was administered twice a day orally until obvious evidence of disease progression or intolerable toxicity was found. Adverse events were recorded according to NCI-CTC criteria. The primary endpoint was overall survival (OS). The secondary endpoints included progression-free survival (PFS), 1-year survival rate, response rate (RR) and safety. Additionally, we detected epithelial growth factor receptor (EGFR) status including EGFR gene amplification by real-time PCR and gene mutations by DHPLC followed by sequencing. Results: The response rate was 45% (20/44), and the disease control rate (DCR) was 59% (26/44). The median progression-free survival time and median survival time were 6 m and 18 m, respectively. The 1-year survival rate was 68%. Chemotherapy cycle numbers and best response were found to be the predictive factors for PFS by COX model analysis (P=0.023 and P=0.000, respectively). No factor was found to affect OS. The most common toxicities included neutropenia and nausea/vomit. EGFR gene amplification was an independent prognostic factor influencing OS (P=0.0002). Patients with EGFR mutations (exon 21) had a tendency of disease progression (P=0.041). Conclusion: Encouraging activities of celecoxib combined with platinum-doublet chemotherapy were demonstrated in treatment-naive patients with advanced NSCLC, with good tolerances. For

    Purpose: To quantify changes of bone marrow microcirculation in multiple myeloma (MM) using contrast enhanced dynamic MRI (dMRI) during thalidomide as antiangiogenic monotherapy or in combination with chemotherapy (cyclophosphamide, etoposide, dexamethasone). Materials and Methods: The study includes 63 patients with refractory or relapsed MM, who underwent dMRI with high temporal resolution (T1w-turboFLASH) of the lumbar spine before and following treatment. The contrast uptake was quantified using a two compartment model with the output parameters amplitude and k{sub ep} (exchange rate constant). The evaluation considered the initial dMRI finding (pathological or non-pathological) and the clinical therapeutic response (response or no response). Results: During monotherapy with thalidomide (n=38), no significant changes of the dMRI parameters were found, even when considering the initial dMRI finding (positive n=22) and the therapeutic response (responder n=14). The combination with chemotherapy (n=25) had a significant reduction of k{sub ep} (p=0.01) in 18 patients with positive initial dMRI finding and therapeutic response. Reduction of the amplitude was seen in most cases, but in the end without any significance (p=0.09). (orig.)

  18. Phase II Trial of Combined Modality Therapy With Concurrent Topotecan Plus Radiotherapy Followed by Consolidation Chemotherapy for Unresectable Stage III and Selected Stage IV Non-Small-Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: The optimal combination of chemotherapy and radiotherapy (RT) and the role of consolidation chemotherapy in patients with locally advanced non-small-cell lung cancer (NSCLC) are unknown. Topotecan is active against NSCLC, can safely be combined with RT at effective systemic doses, and can be given by continuous infusion, making it an attractive study agent against locally advanced NSCLC. Methods and Materials: In this pilot study, 20 patients were treated with infusion topotecan 0.4 mg/m2/d with three-dimensional conformal RT to 63 Gy both delivered Monday through Friday for 7 weeks. Patients without progression underwent consolidation chemotherapy with etoposide and a platinum agent for one cycle followed by two cycles of docetaxel. The study endpoints were treatment response, time to progression, survival, and toxicity. Results: Of the 20 patients, 19 completed induction chemoradiotherapy and 13 completed consolidation. Of the 20 patients, 18 had a partial response and 1 had stable disease after induction chemoradiotherapy. The 3-year overall survival rate was 32% (median, 18 months). The local and distant progression-free survival rate was 30% (median, 21 months) and 58% (median, not reached), respectively. Three patients developed central nervous system metastases, 1 within 228 days, 1 within 252 days, and 1 within 588 days. Three patients had pulmonary emboli. Therapy was well tolerated with 1 of 20 developing Grade 4 lymphopenia. Grade 3 hematologic toxicity was seen in 17 of 20 patients but was not clinically significant. Other Grade 3 toxicities included esophagitis in 3, esophageal stricture in 2, fatigue in 8, and weight loss in 1. Grade 3 pneumonitis occurred in 6 of 20 patients. Conclusion: Continuous infusion topotecan with RT was well tolerated and active in the treatment of poor-risk patients with unresectable Stage III NSCLC

    Purpose: To exam the relationship between HER2 over-expression and different adjuvant chemotherapies in breast cancer. Patients and Methods: A total of 1625 primary breast cancer patients who received post-surgery adjuvant chemotherapy in Tianjin Cancer Hospital, China, from July 2002 to November 2005 were included in the study. Among them, 600 patients were given CMF (CTX+MTX+5-Fu) regimen, 600 given CEF (CTX+E-ADM+5-Fu) regimen, and 425 given anthracyclines plus taxanes regimen, with mean follow-up time of 42 months. Results: In CMF treatment group, the 3-year disease free survival (DFS)in HER2 over-expressed patients was lower than that of the HER2-negative ones (89.80% vs 91.24%, P=0.0348); in node-positive subgroup, the 3-year DFS was 84.72% in HER2 over-expressed patients, and 90.18% in the HER-2-negative ones (P=0.0271).Compared to CMF regimen, anthracyclines and anthracyclines plus taxanes regimens are more effective (P<0.05) in node-positive HER2 over-expression than those in the node-negative. Conclusion: HER2 over-expression is an independent index for predicting poor prognosis and short DFS for breast cancer patients. HER2 over-expressed patients are resistant to CMF regimen chemotherapy, but sensitive to anthracyclines-based or anthracyclines plus taxanes regimen. HER2 expression can be taken as a marker for therapies in breast cancer.

  3. Mortality and morbidity in two-year disease-free survivors of small cell lung cancer after treatment with combination chemotherapy with or without irradiation

    International Nuclear Information System (INIS)

    We evaluated the long-term outcome of 148 patients with small cell lung cancer (SCLC) who had been entered into clinical trials of chemotherapy with or without thoracic and prophylactic cranial irradiation (PCI) between 1981 and 1987. Eighteen patients (12%) survived for 2 or more years. With a minimum follow-up of 4.5 years, 10 of the 18 patients who remained disease-free at 2 years are currently alive and free of SCLC. Seven of these 10 patients currently function as they did before diagnosis. However, three suffer from central nervous system changes of varying degrees in severity which appeared 2-3 years after PCI. Eight of the 18 patients who were disease-free at 2 years have died. Two died of isolated relapse in the brain at 3.6 and 4.2 years after initiation of chemotherapy. Five died of other malignancies while continuing their complete response to SCLC; two of non-small cell lung cancer, two of acute myelogenous leukemia, and one of hepatocellular carcinoma. Another patient died of unrelated disease without any evidence of SCLC. A small but substantial proportion of patients who underwent intensive treatment will achieve long-term survival; however, these patients remain at higher risk for second cancers and late toxicities. Therefore, attention must be directed to defining the safety way to employ such treatment in the management of SCLC. (author)

    The effects of imatinib plus chemotherapy were assessed in 87 patients with newly diagnosed Philadelphia chromosome-positive (Ph(+) ) acute lymphoblastic leukemia (ALL). Imatinib was administered continuously, starting from the eighth day of remission induction chemotherapy, then through five courses of consolidation or until allogeneic hematopoietic cell transplantation (HCT). Patients who were not transplanted were maintained on imatinib for 2 years. Eighty-two patients (94.3%) achieved complete remission (CR). Among these 82 CR patients, 40 experienced recurrence of leukemia. The 5-year relapse free survival (RFS) rate and overall survival (OS) rates were 39.0% and 33.4%, respectively. In total, 56 patients underwent allogeneic HCT in first CR. The 5-year cumulative incidence of relapse and OS rate of them were 59.1% and 52.6%, respectively. Six of seven patients who were maintained on imatinib after completion of consolidation relapsed and the median time of RFS was 40.7 months. In total patient, cumulative molecular CR rate was 88.5% and median time of molecular CR duration was 13 months. Initial imatinib dose intensity was significantly associated with median CR duration (P treatment of patients with Ph(+) ALL, it is important to maintain imatinib dose intensity. PMID:26228525

    Chemotherapy has become a third major treatment option for patients with brain tumors, in addition to surgery and radiotherapy. The role of chemotherapy in the treatment of gliomas is no longer limited to recurrent disease. Temozolomide has become the standard of care in newly diagnosed glioblastoma. Several ongoing trials seek to define the role of chemotherapy in the primary care of other gliomas. Some of these studies are no longer only based on histological diagnoses, but take into consideration molecular markers such as MGMT promoter methylation and loss of genetic material on chromosomal arms 1p and 19q. Outside such clinical trials chemotherapy is used in addition to radiotherapy, e.g., in anaplastic astrocytoma, medulloblastoma or germ cell tumors, or as an alternative to radiotherapy, e.g., in anaplastic oligodendroglial tumors or low-grade gliomas. In contrast, there is no established role for chemotherapy in other tumors such as ependymomas, meningiomas or neurinomas. Primary cerebral lymphomas are probably the only brain tumors which can be cured by chemotherapy alone and only by chemotherapy. The chemotherapy of brain metastases follows the recommendations for the respective primary tumors. Further, strategies of combined radiochemotherapy using mainly temozolomide or topotecan are currently explored. Leptomeningeal metastases are treated by radiotherapy or systemic or intrathecal chemotherapy depending on their pattern of growth. PMID:18253773

    The prognosis of stage III non-small cell lung cancer (NSCLC) can be improved by a combination of radiotherapy (RT) and chemotherapy (CT). In this study, the GOTHA group evaluated the feasibility, tolerance, tumour response, pattern of failure and effect on survival of a combination alternating accelerated hyperfractionated (AH) RT and CT in patients with tumour stage III NSCLC. Toxic effects were leucopenia, nausea and vomiting, mucositis, diarrhoea, alopecia and peripheral neuropathy. Alternating CT and AHRT, as used in this study, were well tolerated and allowed full dose delivery within less than 12 weeks. Initial response was not predictive of survival. The survival curve is encouraging and the 5 year survival is superior to the 5% generally observed with conventionally fractionated radiotherapy. (author).

    Androgen deprivation in patients with metastatic prostate cancer produces palliation of symptoms, PSA decrease and tumoral regression in most patients. After a brief period of disease regression lasting 18 to 24 months nearly all pts will progress to androgen independence disease (HRPC) with progressive clinical deterioration and ultimately death. Chemotherapy with mitoxantrone has been shown to palliate symptoms but did not extend survival. Two large randomized trials showed a survival benefit for pts with HRPC treated with docetaxel with a reduction risk of death by 21-24%, and significant improvement in palliation of symptoms and quality of life. New agents targeting angiogenesis, apoptosis, signal transduction pathway, used alone or in combination with docetaxel currently are under trial in an attempt to provide much needed improvements in outcome. Questions remains in suspend when and who need to be treated, earlier, in high risk as in adjuvant setting? Current data have demonstrated that neoadjuvant or adjuvant chemotherapy is relatively safe and feasible. Further investigation through prospective randomize trials is critical to define the precise role of this modality in high risk populations. PMID:17845990

    Sorafenib has been a standard therapy for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. Hepatic arterial infusion chemotherapy (HAIC) is still preferably performed in Japan because of its relatively good tumor-shrinking effect. We report a case of advanced multiple HCC with portal thrombus that responded to combination chemotherapy with sorafenib and repeat hepatic arterial infusion with a fine-powder formulation of cisplatin (IA-call®). A 57-year-old man presented for the treatment of HCC with alcoholic cirrhosis. Multiple HCC were found to be rapidly progressing with portal thrombosis. HAIC with IA-call® was performed, but the tumors progressed. TAE was performed 3 times thereafter and the main tumor shrunk to some extent. A month after the last TAE, the HCC was found to progress again, and oral sorafenib was administered. A reservoir and catheter were placed and HAIC with low-dose 5-fluorouracil and cisplatin was performed for 3 cycles following 1 HAIC cycle with epirubicin and mitomycin C, which was not effective. For 10 months after initial therapy, HAIC using IA-call® has been performed once for 6 weeks. After performing HAIC with IA-call® 5 times, the serum levels of HCC tumor markers AFP and PIVKA-Ⅱdecreased, and the tumors continued to shrink and were not stained on enhanced CT scan. The patient has been alive for 23 months after the initial therapy and has maintained stable disease. PMID:26805203

    International Nuclear Information System (INIS)

    The authors assessed the outcome in 252 patients with small-cell lung cancer 5 to 11 years after treatment with combination chemotherapy, with or without chest and cranial irradiation, in National Cancer Institute therapeutic trials from 1973 through 1978. Twenty-eight patients (11%) survived free of cancer for 30 months or more. Fourteen patients remain alive without evidence of cancer beyond 5 years, and 7 patients have returned to a lifestyle similar to that before diagnosis. The other 14 patients who were cancer-free at 30 months have developed cancer or died. A few patients with small-cell lung cancer (5.6%) may be cured. Thirty-month, cancer-free survival is insufficient to show a cure. Although late toxicities are troublesome, they do not outweigh the benefits of prolonged survival and potential for cure with modern aggressive therapy in small-cell lung cancer

    Purpose: The development of breast cancer-related lymphedema (LE) is closely related to the number of dissected axillary lymph nodes (N-ALNs), chemotherapy, and radiation therapy. In this study, we attempted to estimate the risk of LE based on combinations of these treatment-related factors. Methods and Materials: A total of 772 patients with breast cancer, who underwent primary surgery with axillary lymph node dissection from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 677 patients (88%). Among patients who received radiation therapy (n=675), 274 (35%) received supraclavicular radiation therapy (SCRT). Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 127 patients had developed LE. The overall 5-year cumulative incidence of LE was 17%. Among the 127 affected patients, LE occurred within 2 years after surgery in 97 (76%) and within 3 years in 115 (91%) patients. Multivariate analysis showed that N-ALN (hazard ratio [HR], 2.81; P<.001), ACT (HR, 4.14; P=.048), and SCRT (HR, 3.24; P<.001) were independent risk factors for LE. The total number of risk factors correlated well with the incidence of LE. Patients with no risk or 1 risk factor showed a significantly lower 5-year probability of LE (3%) than patients with 2 (19%) or 3 risk factors (38%) (P<.001). Conclusions: The risk factors associated with LE were N-ALN, ACT, and SCRT. A simple model using combinations of these factors may help clinicians predict the risk of LE.

    Purpose: Concurrent cisplatin-based chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical cancer. RTOG 0417 was a Phase II study exploring the safety and efficacy of the addition of bevacizumab to standard CRT. Methods and Materials: Eligible patients with bulky tumors (Stage IB-IIIB) were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiotherapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for three cycles. Treatment-related serious adverse event (SAE) and other adverse event (AE) rates within the first 90 days from treatment start were determined. Treatment-related SAEs were defined as any Grade {>=}4 vaginal bleeding or thrombotic event or Grade {>=}3 arterial event, gastrointestinal (GI) bleeding, or bowel/bladder perforation, or any Grade 5 treatment-related death. Treatment-related AEs included all SAEs and Grade 3 or 4 GI toxicity persisting for >2 weeks despite medical intervention, Grade 4 neutropenia or leukopenia persisting for >7 days, febrile neutropenia, Grade 3 or 4 other hematologic toxicity, and Grade 3 or 4 GI, renal, cardiac, pulmonary, hepatic, or neurologic AEs. All AEs were scored using the National Cancer Institute Common Terminology Criteria (CTCAE) v 3.0 (MedDRA version 6.0). Results: A total of 60 patients from 28 institutions were enrolled between 2006 and 2009, and of these, 49 patients were evaluable. The median follow-up was 12.4 months (range, 4.6-31.4 months).The median age was 45 years (range, 22-80 years). Most patients had FIGO Stage IIB (63%) and were of Zubrod performance status of 0 (67%). 80% of cases were squamous. There were no treatment-related SAEs. There were 15 (31%) protocol-specified treatment-related AEs within 90 days of treatment start; the most common were hematologic (12/15; 80%). 18 (37%) occurred during treatment or follow-up at any time. 37 of the 49 patients (76%) had cisplatin and bevacizumab

    Introduction. We prospectively evaluated concomitant radiotherapy and chemotherapy for advanced bladder cancer in a phase II EORTC trial to test whether it could be further studied as a potential treatment of bladder cancer. Patients and methods. Patients up to 75 years of age with invasive transitional-cell carcinoma of the bladder up to 5 cm, stage pT2 to pT3b, N0M0, without residual macroscopical tumour after transurethral excision were eligible. Radiotherapy consisted of 2 fractions of 1.2 Gy daily up to 60 Gy delivered in a period of 5 weeks. During the first and the last week, cisplatin 20 mg/m2/day and 5 FU 375 mg/m2/day were given concomitantly. Results. The study was interrupted early due to poor recruitment. Nine patients of the originally 43 planned were treated. Mean age was 63 years. Five patients had tumour stage pT2, 1 stage pT3a and 3 stage pT3b. All patients completed radiotherapy and chemotherapy as scheduled. Only one grade 3 and no grade 4 toxicity was seen. All patients were evaluated 3 months after treatment: eight patients had no detectable tumour and one had para-aortic lymph nodes. During further follow-up, a second patient got lymph node metastases and two patients developed distant metastases (lung in the patient with enlarged lymph nodes at the first evaluation and abdominal in one other). Those three patients died at respectively 19, 14, and 18 months after registration. Late toxicity was limited and often temporary. After 26 to 57 months of follow-up, no local recurrences were seen. Six patients remained alive without disease. Discussion. Despite the small cohort, this combination of concomitant chemotherapy and accelerated hyperfractionated radiotherapy for invasive bladder cancer seemed to be well tolerated and to result in satisfactory local control with limited early and late toxicity. It could therefore be considered for study in further clinical trials

    Dendritic cells (DC) play a crucial role in the induction of an effective antitumor immune response. Cytokine-induced killer (CIK) cells, a subset of T lymphocytes, have the capacity to eliminate cancer cells. This study was to evaluate the correlation between the frequency of DC/CIK immunotherapies following regular chemotherapy, the time-to-progression (TTP), and overall survival (OS) of advanced non-small lung cancer patients. Sixty patients with IIIB-IV non-small-cell lung carcinoma (NSCLC) were enrolled from August 2007 to December 2009 and were randomized into two groups. All 60 patients received four courses of navelbine-platinum (NP) chemotherapy. In one group, 30 patients were treated with adoptive autologous DC/CIK cell transfusion twice every 30 days. In the other group, the patients received immunotherapies more than twice every 30 days. The adverse effects, TTP, and OS were evaluated between the two groups. Median survival time of all 60 patients was 13.80 months. The 1-, 2-, and 3-year overall survival rates were 60.0, 21.7, and 15.0 %, respectively. The 1-, 2-, and 3-year overall survival rates of patients receiving more than two immunotherapies were 63.3, 30.0, and 23.3 %, and the rates of those receiving two immunotherapies were 56.7, 13.3, and 6.7 %, respectively. The difference between the two groups was statistically significant (P = 0.037). Compared with patients in the fewer immunotherapies group, TTP in the group receiving more immunotherapies significantly prolonged, with the median improving from 6.2 months (95 % CI, 5.35-9.24) to 7.3 months (95 % CI, 5.45-6.95; P = 0.034). The adverse effects of chemoimmunotherapy were tolerable. Advanced NSCLC patients can benefit from the combination of DC/CIK immunotherapies following conventional chemotherapy. More than two immunotherapies improved TTP and OS of those patients in this study. PMID:24006222

  10. The results of a single center pilot study of combined high-dose methotrexate and doxorubicin with cisplatin in neo-adjuvant chemotherapy for osteosarcoma in children and adolescents

    International Nuclear Information System (INIS)

    The study summarizes the treatment results of a newly introduced protocol for high-grade osteosarcoma, combining high dose of methotrexate alternating with doxorubicin and cisplatin. The efficacy of preoperative chemotherapy, evaluated as a proportion of necrotic cells assessed in a primary tumor map, was compared with results achieved in historical studies comprising two modalities: doxorubicin and high dose of methotrexate (the so called SFOPprotocol) or doxorubicin and cisplatin (the so-called EORT protocol) only. Additionally, we performed a comparative analysis of early toxicity of all the three protocols. Apart from statistically insignificant differences between the results of all the three protocols, we have demonstrated that the efficacy of the currently introduces protocol exceeds that of the SFOP protocol and is comparable to the EORTC protocol (48.5% vs. 44% and 49%, respectively), with only two cycles of cardiotoxic doxorubicin applied in the current protocol. The proportion of limb saving procedures in the current protocol (82%>) was comparable to SFOP (85%) and exceeded that achieved in the EORTC protocol (48%). Progression of tumor mass was observed in 4% of patients treated according to the EORTC protocol, in 10% of currently assessed patients and in 44% of patients treated according to the SFOP protocol. Acute toxicity of cytostatics requiring withholding ongoing chemotherapy was considerably less common in the SFOP group (36%), when compared to current protocol (2.5%) and the EORTC protocol (0%). The results of this pilot study demonstrate the comparable or even higher efficacy and safety of the currently introduced protocol as compared to the historical treatment protocols in patients with high-grade osteosarcoma. The comprehensive results of the study and the final assessment of the safety and the efficacy of the currently introduced protocol calls for a long observation period and a larger patient group.

    To evaluate the value of F-fluorodeoxyglucose-positron emission tomography/computed tomography (F-FDG PET/CT) and pretherapeutic Ki67 in predicting pathologic response in locally advanced breast cancer (LABC) after neoadjuvant chemotherapy (NAC).As a training set, total 301 LABC patients treated with NAC were retrospectively analyzed to evaluate the potential predictive value of pretherapeutic Ki67 for pathologic complete response (pCR) after NAC. Another 60 LABC patients were prospectively included as a validation set to evaluate the value of Ki67 combined PET/CT as pCR predictors. Ki67 was assessed in pretherapy core needle biopsy specimens and PET/CT scans were performed at baseline (before initiating NAC), after the 2nd, and 4th cycle of NAC. Maximum standardized uptake value (SUVmax) and its changes relative to baseline (ΔSUVmax%) were used as parameters of PEC/CT.In the training set, Ki67 was a predictor of pCR to NAC, with area under the curve (AUC) of 0.624 (P = 0.003) in receiver-operating characteristic (ROC) analysis. In the validation set, Ki67 alone did not show significant value in predicting pCR in the validation set. ΔSUVmax% after then 2nd or 4th course are predictors of pCR to NAC with the AUC of 0.774 (P = 0.002) and 0.791 (P = 0.002), respectively. When combined with ΔSUVmax% after the 2nd and 4th course NAC, Ki67 increased the value of ΔSUVmax% in predicting pCR with the AUC of 0.824 (P = 0.001). Baseline SUVmax and after 2nd, 4th course NAC had no predictive value for pCR, but SUVmax after the 2nd and 4th course showed remarkable predictive value for nonpathologic response (Grade 1 in Miller-Payne Grading System) with the AUC of 0.898 (P = 0.0001) and 0.801 (P = 0.003).Both PET/CT and Ki67 can predict pCR to NAC in LABC patients in the early phases of treatment. PET/CT combined Ki67 is a better pCR predictor for response to NAC. This helps the physician to predict the probability of pCR, and facilitates the

    Full Text Available Purpose: The main purpose of this study was to analyze the effects and tolerability of Oxaliplatin-Vinorelbine combination on Platinum-resistant epithelial ovarian carcinoma (EOC patients.Methods: A single centered retrospective study comprising of 34 patients was conducted, and all 34 patients were treated with Vinorelbine 30 mg/m2 on day 1 and 8 along with Oxaliplatin 100 mg/m2 on day 1 of 3 weeks treatment cycle following progressive platinum-resistant EOC. Results: The combination showed an overall response rate (ORR of 18% (95% CI, 4.4 - 31.6 where 2 (6% patients had complete response and 4 (12% patients had partial response. Stable disease was observed in 9 (26% patients and progressive disease in 19 (56% patients. Median diseases free survival, median relapse free survival and median time to progression was 17.05 months, 4.4 months, and 1.25 months, respectively. Hematological toxicities were mild; only 1 (2.9% patient had G3 anemia and major non-hematological toxicities include nausea-vomiting, diarrhea, constipation, hepatotoxicity, fatigueness and alopecia, which are mainly limited to G1-G2 and reversible. Conclusion: The effect of this combination is moderate as a second line treatment of platinum resistant EOC; however, in comparison with other regimens of Vinorelbine and Oxaliplatin, the activity is substandard but the toxicity profile is well tolerable. Further multicenter evaluation is needed for the better understanding of the therapeutic efficacy of the combination.

    BACKGROUND: Post-chemotherapy nausea remains a significant burden to cancer patients. While some studies indicate that expecting nausea is predictive of experiencing nausea, there are a number of conflicting findings. PURPOSE: The purpose of this study was to conduct a meta-analytic review to...... determine the strength of the relationship between expectancy and post-chemotherapy nausea. METHODS: The findings from 17 relevant studies (n = 2,400) identified through systematic searches of Medline, PsycInfo, and Cinhal were analyzed using a combination of meta-analytic techniques. RESULTS: Overall......, there was a robust positive association between expectancy and post-chemotherapy nausea (ESr = 0.18, equivalent to Cohen's d = 0.35), suggesting that patients with stronger expectancies experience more chemotherapy-induced nausea. Although weaker associations were found in studies employing multivariate...

    Chemotherapy may have detrimental effects on either the central or peripheral nervous system. Central nervous system neurotoxicity resulting from chemotherapy manifests as a wide range of clinical syndromes including acute, subacute, and chronic encephalopathies, posterior reversible encephalopathy, acute cerebellar dysfunction, chronic cognitive impairment, myelopathy, meningitis, and neurovascular syndromes. These clinical entities vary by causative agent, degree of severity, evolution, and timing of occurrence. In the peripheral nervous system, chemotherapy-induced peripheral neuropathy (CIPN) and myopathy are the two main complications of chemotherapy. CIPN is the most common complication, and the majority manifest as a dose-dependent length-dependent sensory axonopathy. In severe cases of CIPN, the dose of chemotherapy is reduced, the administration delayed, or the treatment discontinued. Few treatments are available for CIPN and based on meta-analysis, duloxetine is the preferred symptomatic treatment. Myopathy due to corticosteroid use is the most frequent cause of muscle disorders in patients with cancer. PMID:27443648

    Background:Both hormonal therapy (HT) and maintenance capecitabine monotherapy (MCT) have been shown to extend time to progression (TTP) in patients with metastatic breast cancer (MBC) after failure of taxanes and anthracycline‑containing regimens. However, no clinical trials have directly compared the effcacy of MCT and HT after response to ifrst‑line capecitabine‑based combination chemotherapy (FCCT) in patients with hormone receptor (HR)‑positive and human epidermal growth factor receptor 2 (HER2)‑negative breast cancer. Methods:We retrospectively analyzed the charts of 138 HR‑positive and HER2‑negative MBC patients who were in non‑progression status after FCCT and who were treated between 2003 and 2012 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences, in Beijing, China. The median number of ifrst‑line chemotherapy cycles was 6 (range, 4–8); combined agents included taxanes, vinorelbine, or gemcitabine. Of these 138 patients, 79 received MCT, and 59 received HT. Single‑agent capecitabine was administered at a dose of 1250mg/m2 twice daily for 14days, followed by a 7‑day rest period, repeated every 3weeks. Of the 59 patients who received HT, 37 received aromatase inhibitors (AIs), 8 received selective estrogen receptor modulators (SERMs), and 14 received goserelin plus either AIs or SERMs. We then compared the MCT group and HT group in terms of treatment effcacy. Results:With a median follow‑up of 43months, patients in the HT group had a much longer TTP than patients in the MCT group (13 vs. 8months,P=0.011). When TTP was adjusted for age, menopausal status, Karnofsky performance status score, disease‑free survival, site of metastasis, number of metastatic sites, and response status after FCCT, extended TTP was still observed for patients in the HT group (hazard ratio: 0.63; 95% conifdence interval: 0.44–0.93;P=0.020). We also observed a trend of overall survival advantage for patients in the HT group vs

    Arecent source data meta-analysis of randomized trials in adults assessing the immunoconjugate gemtuzumab ozogamicin combined with standard chemotherapy in acute myeloid leukemia showed a significant survival benefit in patients without an adverse karyotype. It is not clear whether the optimal dose should be 3 mg/m2 or 6 mg/m2. In this study, we randomized 788 patients to a single dose of gemtuzumab ozogamicin 3 mg/m2 or 6 mg/m2 with the first course of induction therapy. We found that the rate of complete remission was higher with 3 mg/m2 [82% vs. 76%; odds ratio 1.46 (1.04–2.06); P=0.03], but this was balanced by a higher rate of complete remission with incomplete peripheral blood count recovery in the 6 mg/m2 treatment (10% vs. 7%) resulting in similar overall response rate [89% vs. 86%; hazard ratio 1.34 (0.88–2.04); P=0.17]. There was no overall difference in relapse or survival at four years between the arms: 46% vs. 54%; hazard ratio 1.17 (0.94–1.45), P=0.5, and 50% versus 47%; hazard ratio 1.10 (0.90–1.34), P=0.3, respectively. The 30- and 60-day mortality was significantly higher in the 6 mg/m2 recipients: 7% versus 3%; hazard ratio 2.07 (1.11–3.87), P=0.02, and 9% versus 5%; hazard ratio 1.99 (1.17–3.39), P=0.01, respectively, which in addition was associated with a higher rate of veno-occlusive disease (5.6% vs. 0.5%; P<0.0001). Our conclusion from this trial is that there is no advantage in using a single dose of 6 mg/m2 of gemtuzumab ozogamicin in combination with induction chemotherapy when compared with a 3 mg/m2 dose, with respect to response, disease-free and overall survival, either overall, or in any disease subgroup. (AML17 was registered as ISRCTN55675535.) PMID:26921360
