    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.

    This paper presents the clinically confirmed benefits of combined chemotherapy-radiotherapy. They have been found in a small group of diseases that respond to chemotherapy alone. According to the author, only when a drug or drug combination has the ability to eradicate occult disease or substantially to reduce the size of objectively measurable disease is there likely to be an demonstrable benefit from its use in conjunction with radiotherapy. It is the author's belief that the immediate future lies in selecting drugs and patients in which a good chemotherapeutic response can be expected, avoiding drugs that seriously enhance radiation damage to normal tissues and keeping drug and radiation treatments far enough apart in time to minimize interactions

    It is shown that chemotherapy of tumors of various localizations developes intensively in the last few years. It is connected with discovery and adoption of new active antitumoral preparations, such as alkylating preparations, antimetabolites, antitumoral antibiotics, hormonal preparations. To create the rational effective conditions of chemotherapy a study was made on kinetics of tumor gowth, molecular mechanisms of interaction of cytostatics and cells of malignant tumor. Main factors of chemotherapy combination with radiotherapy when treating numerous malignant tumors were considered. Effectiveness of using chemotherapy in combination with other methods of treatment was shown

    There are 4 modalities of combined radiotherapy and chemotherapy which include (1) concurrent radiotherapy and chemotherapy, (2) sequential use of radiotherapy and chemotherapy (pre-radiation chemotherapy), (3) pre-radiation chemotherapy followed by concurrent radiation and chemotherapy, and (4) alternating use of radiotherapy and chemotherapy based upon Looney's hypothesis. We studied concurrent use of radiotherapy and UFT by means of animal experimentation and clinical trials. The results obtained revealed that UFT was a most suitable agent together with 5-fluorouracil for concurrent application of radiotherapy and chemotherapy. Neo-adjuvant chemotherapy including pre-radiation chemotherapy was also studied in cases of maxillary sinus carcinoma and nasopharyngeal carcinoma. From the results, it seemed desirable to use cisplatin and bleomycin analogs sequentially in combined chemotherapy and radiotherapy. Neo-adjuvant chemotherapy should be studied successively to improve local tumor control rates and prevent distant metastases. For future perspectives, new trials of alternating radiotherapy and chemotherapy based upon Looney's hypothesis seem necessary. (author)

    In the present work an attempt was made to gain greater therapeutic effect of diazane coupled with adriamycin and sarcolysin. Leucemias L-1210 and La served as a model. In leucosis La diazane was injected once in 5 days. Either an additional injection of adriamycin two days prior to diazane injection or sarcolysin injected simultaneously with diazane enabled the authors to obtain a distinct synergestic effect. In leucemia L-1210 a simultaneous administration of diazane and sarcolysin also contributes to considerably longer survival of leucemic animals. Such combinations are likely to be promising in their clinical use.

    In clinical application of radiation therapy combined with chemotherapy, it is important to gain the maximal therapeutic benefit. At present we have no agents that improve the therapeutic ratio by enhancing the effect of radiation on the tumor cell selectively. Therefore, it is necessary to use combining some or all of following procedures: (1) the intraarterial infusion of the agents, (2) the selective localization by reason of the biological affinity of the agents, (3) the surgical removal of the non-sensitized tumor residue and (4) the selective sensitization of the tumor due to its shorter cell cycle.

    The present paper discusses some of the methodological issues which can confound the interpretation of clinical trials of combined modality treatment. It reviews some of the larger randomized trials which have evaluated combined modality treatment in cancers of the head and neck, lung, gastrointestinal tract and bladder. It concludes that adequate trials have yet to be performed in many of thses sites, but that at present, evidence for long-term benefit from adjunctivechemotherapy is meagre. Finally, it suggests some possible mechanisms which might heve limited the benefit of chemotherapy when added to radiation treatment. (Author). 87 refs.; 4 figs.; 4 tabs

    Forty-three postmenopausal breast cancer patients with axillary lymph node metastasis were randomized to receive postoperative radiotherapy (45 Gy) or the combination of radiotherapy and 6 months of chemotherapy. Forty-three premenopausal patients had postoperative radiotherapy and were randomized to receive one of two different chemotherapy combinations. Pulmonary fibrosis was roentgenologically registered in approximately 70% of the total patient population six months after initiation of therapy. Addition of chemotherapy with doxorubicin and cyclophosphamide significantly increased the proportion of patients with pulmonary fibrosis compared with patients treated with radiotherapy only or radiotherapy combined with cyclophosphamide, methotrexate and 5-fluorouracil. Premenopausal patients tolerated the combination of radiotherapy and chemotherapy better than postmenopausal patients of whom approximately 30% did not tolerate 65% or more of prescribed total dose of chemotherapy.

    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 significance of combination of chemotherapy in radiotherapy for esophageal cancer was evaluated in 32 patients. They were irradiated routinely in 5 times a weeks with a fraction dose of 200 rad by 10MV-X-ray linear accelerator. Combined drugs consist of Bleomycin or Pepleomycin in two-third and 5FU or FT-207 in one-third. There was statistically no significance between the results of radiation alone and combined chemotherapy, and the improvement of survival rate could not be obtained by combining chemotherapy. Some discussion on the causes of this unimprovement were made. (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)

    While conventional chemotherapy is effective at eliminating the bulk of leukemic cells, chemotherapy resistance in acute myeloid leukemia (AML) is a prevalent problem that hinders conventional therapies and contributes to disease relapse, and ultimately patient death. We have recently shown that allogeneic double negative T cells (DNTs) are able to target the majority of primary AML blasts in vitro and in patient-derived xenograft models. However, some primary AML blast samples are resistant to DNT cell therapy. Given the differences in the modes of action of DNTs and chemotherapy, we hypothesize that DNT therapy can be used in combination with conventional chemotherapy to further improve their anti-leukemic effects and to target chemotherapy-resistant disease. Drug titration assays and flow-based cytotoxicity assays using ex vivo expanded allogeneic DNTs were performed on multiple AML cell lines to identify therapy-resistance. Primary AML samples were also tested to validate our in vitro findings. Further, a xenograft model was employed to demonstrate the feasibility of combining conventional chemotherapy and adoptive DNT therapy to target therapy-resistant AML. Lastly, blocking assays with neutralizing antibodies were employed to determine the mechanism by which chemotherapy increases the susceptibility of AML to DNT-mediated cytotoxicity. Here, we demonstrate that KG1a, a stem-like AML cell line that is resistant to DNTs and chemotherapy, and chemotherapy-resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin. Moreover, chemotherapy treatment followed by adoptive DNT cell therapy significantly decreased bone marrow engraftment of KG1a in a xenograft model. Mechanistically, daunorubicin increased the expression of NKG2D and DNAM-1 ligands on KG1a; blocking of these pathways attenuated DNT-mediated cytotoxicity. Our results demonstrate the feasibility and benefit of using DNTs as

    Sequential chemotherapy using FT-207, adriamycin and mitomycin C followed by radiotherapy was attempted to achieve effective inhibition against implanted tumor in C57BL/6 black mice bearing YM-12 tumors. Sequential combined chemotherapy was more effective than single drug chemotherapy or combined chemotherapy of other drugs. Addition of radiotherapy to the sequential combined chemotherapy was successful for enhancing therapeutic effect. (author)

    Fifty-six patients with carcinoma of the lung treated with radiotherapy alone or combination of chemotherapy were reviewed. Radiation was given with a 10MV photon beam by a linear accelerator. A fraction dose of 2Gy (200 rad) was given routinely 5 times a week. Combined durgs consist of 5FU or FT-207 in monochemotherapy and METT, MFC, or METVFC in combination chemotherapy. 5 year survival rate of all patients was 3.8%. As for the stage classification, 5 year survival rate is 30% in Stage I and II cancer, but there was no 3 year survivor in Stage III cancer and 2 year survivor in Stage IV cancer. As for the cell types, cases of adenocarcinoma had worse prognosis than them of squamous cell carcinoma and small cell carcinoma. The prognosis of patients treated with combination of radiotherapy and chemotherapy was similar to that of patients treated with radiotherapy alone. These results suggest that combined chemotherapy did not influence tumor control. Some discussion on the treatment modality of chemotherapy are made, emphasizing untoward effect of chemotherapy on immunopotency. (author)

    There are two purposes of using combined chemotherapy and radiotherapy in the treatment of cancers. One is to suppress distant metastasis, especially micrometastasis; the other is to improve localized control. As a trial of the utility of the former, systemic chemotherapy with CDDP and 5 FU was given successively with radiotherapy to treat nasopharyngeal cancer. The survival rate was significantly improved compared with historical control cases. The main reason for this effectiveness was the improvement of localized control. The suppression of distant metastasis is the subject of future research. As a trial of the utility of the latter, a super-selective intraarterial chemotherapy with CBDCA combined with radiotherapy was used to head and neck localized progressive cancers. The control of localized cancer was remarkably effective. This treatment is considered to be especially suitable for locally advanced tongue cancer and cancer of the root of the tongue. (author)

Biological targeted treatment to date has minor effect when given as monotherapy, but some of the drugs hold promise as an adjunct...... to chemotherapy. It should, however, be noted that most of the trials are based on few patients, and thus far the literature does not allow for a conclusion as to the role of biological treatment on cholangiocarcinoma.

    The prognosis of the patients with advanced esophageal carcinoma treated by definitive radiotherapy is still dismal with a reported 5-year survival rate of 5-10% in most series. Since 1986, combined radiotherapy with chemotherapy using platinum analogue was initiated at Asahikawa and Obihiro Kosei Hospitals in order to improve local-regional control and the survival of the patients. From 1980 to 1992, 81 patients with unresectable esophageal carcinoma were treated with radiotherapy. Since April 1986, 37 out of the 81 patients received both radiotherapy and chemotherapy with platinum. Platinum was used during the course of radiotherapy. The method of administration of platinum was as follows; Cisplatin intravenously (50 mg, weekly, total 200 mg) in 9 patients, Carboplatin intravenously (100-150 mg, weekly, total 400-900 mg) in 11 patients and Cisplatin intraarterially (100 mg, at a 3-4 week interval, total 100-300 mg) in 17 patients. These 37 patients (Group A) were compared to 44 patients treated by radiotherapy alone (Group B) with respect to initial response and survival rate. Response was defined according to the guidelines recommended by Japanese Society for Esophageal Diseases. Response rates were 59.1% (19 CR and 7 PR) in Group B and 70.3% (7 CR and 19 PR) in Group A. Primary relapse-free rates were 36.4% in Group B and 37.8% in Group A. The cumulative survival at 3 years were 11.7% in Group B and 10.6% in Group A. Enhancement of side effects by chemotherapy was minimal and acceptable. Improvement of local-regional control and survival was not obvious by adding a concomitant platinum-chemotherapy. A definite conclusion, however, could not be drawn because of the retrospective, non-controlled nature of this study. Introduction of more intensive, multiple agents chemotherapy seems necessary if one aims at improving the results. (author)

    Combined chemotherapy and radiation therapy has been established as standard treatment approach for locally advanced head and neck cancer, esophageal cancer and so on through randomized clinical trials. However, radiation-related morbidity such as acute toxicity also increased as treatment intensity has increased. In underlining mechanism for enhancement of normal tissue reaction in chemo-radiation therapy, chemotherapy enhanced radiosensitivity of normal tissues in addition to cancer cells. Molecular target-based drugs combined with radiation therapy have been expected as promising approach that makes it possible to achieve cancer-specific enhancement of radiosensitivity, and clinical trials using combined modalities have been performed to evaluate the feasibility and efficacy of this approach. In order to obtain maximum radiotherapeutic gain, a detailed understanding of the mechanism underlying the interaction between radiation and Molecular target-based drugs is indispensable. Among molecular target-based drugs, inhibitors targeting epidermal growth factor receptor (EGFR) and its signal transduction pathways have been vigorously investigated, and mechanisms regarding the radiosensitizing effect have been getting clear. In addition, the results of randomized clinical trials demonstrated that radiation therapy combined with cetuximab resulted in improvement of overall and disease-specific survival rate compared with radiation therapy in locally advanced head and neck cancer. In this review, clinical usefulness of chemo-radiation therapy and potential molecular targets for potentiation of radiation-induced cell killing are summarized. (author)

    The management of ovarian carcinoma is difficult mainly due to the fact that ovary, unlike other organs in the body remains the seat of wide variety of histological type of tumor with even wider biological behaviour and response to each modality of treatment. The objective of present paper is to evaluate the changing policy towards this tumor with emphasis on the combination plan in general and chemotherapy supplement in particular. Prognosis of advanced cancer which forms the bulk of the cases almost in every centre remains dismal. In this group of patients in a retrospective analysis, a guideline of treatment has been formulated. (auth.)

    Lung and prostate cancers are major health problems worldwide. Treatments with standard chemotherapy agents are relatively ineffective. Combination chemotherapy gives better treatment than a single agent because the drugs can inhibit the cancer in different pathways, but new therapeutic agents are needed for the treatment of both tumor types. Bradykinin (BK) antagonists offer advantages of combination therapy in one compound. These promising multitargeted anti-cancer compounds selectively stimulate apoptosis in cancers and also inhibit both angiogenesis and matrix metalloprotease (MMP) action in treated lung and prostate tumors in nude mice. The highly potent, metabolism-resistant bradykinin antagonist peptide dimer, B-9870 [SUIM-(DArg-Arg-Pro-Hyp-Gly-Igl-Ser-DIgl-Oic-Arg)2] (SUIM=suberimidyl; Hyp=4-hydroxyproline; Igl=alpha-(2-indanyl)glycine; Oic=octahydroindole-2-carboxylic acid) and its non-peptide mimetic, BKM-570 [2,3,4,5,6-pentafluorocinnamoyl-(o-2,6-dichlorobenzyl)-L-tyrosine-N-(4-amino-2,2,6,6-tetramethylpiperidyl)amide] are superior to the widely used but toxic chemotherapeutic drugs cisplatin and taxotere. In certain combinations, they act synergistically with standard anti-cancer drugs. Due to its structure and biological activity, BKM-570 is an attractive lead compound for derivatization and evaluation for lung and prostate cancer drugs.

    The concurrent combination therapy of radiation and chemotherapy was performed in a total of 134 cases of stomach cancer. Radiation response of tumor was remarkable in 35 (37%) of 95 cases, irradiated more than 5,000 rad. Yearly survival rates in 81 cases, in which the scheduled curative treatment was completed, were 63% in one, 31% in two, 21% in three, 17% in four and 13% in five years. These rates were intimately correlated to tumor size and cancer type. However, this combination therapy accompanied some fatal complications in a few percent. From the results, it was concluded that this combination therapy should be valuable to prolong the life of patients with gastric cancer, and that the curable indications for this treatment should be T1-T3: M0 cases with radio-responsive tumor.

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

    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.)

    The indications for a combined radio- and chemotherapy can be summarized from three points of view: 1) Intensifying local radiotherapy by chemotherapy. 2) Extending local radiotherapy by systematical chemotherapy. 3) Supporting chemotherapy by radiotherapy. The side effects of the combination are discussed, classified as immediate type and long-term type. It is indicated that in all combinations the drug-specific and/or organ-specific side effects of the cytostatics must be taken into consideration. The substantial therapeutical aspect lies in prophylaxis. Exact data concerning the reduction of the dosage of the radiotherapy and/or the chemotherapy must be found after exact observation of the complications. Knowing the side effects of the immediate-type and taking into consideration the long-term damage which can be expected, there are today clear indications for a combined radio- and chemotherapy.

    In the past decade the prognosis of patients with locally advanced lung cancer has not been altered significantly. In both small and non-small cell lung cancer cure rates are poor and 5-year survival rate still has not exceeded the 5% borderline. Despite of initially high response rates, a vast majority of patients suffered from tumor progression within 2 years after the start of treatment. Sites of tumor progression are either the primary tumor or the occurrence of distant metastases. Therefore, improvements of both local and systemic tumor control are necessary to increase long-term survival rate in lung cancer. Combined chemo- and radiotherapy may be an appropriate treatment approach to reach these aims. In patients with locally advanced lung cancer combined chemo-radiotherapy aims at overcoming radio- and chemo-therapy resistance as a cause of local treatment failure and at early eradication of distant micrometastases as a cause of systemic treatment failure.

  10. 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

    Between 2009 and 2012, 10 patients with advanced oropharyngeal cancer underwent proton therapy combined with chemotherapy. The initial results of this therapy were 8 complete response (CR) and 2 partial response (PR), local recurrence was detected 1 patient. Proton beam therapy combined with chemotherapy is thought to be an effective treatment for locally advanced oropharyngeal cancer. (author)

    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

    The aim is to evaluate the preliminary efficacy and side effects of paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy in combination with cisplatin hyperthermic intraperitoneal perfusion chemotherapy (HIPEC) as postoperative adjuvant therapy for patients of locally advanced gastric cancer (GC) at high risk for recurrence after curative resection. Four GC patients who underwent radical gastrectomy with D2 lymphadenectomy were enrolled. All patients received paclitaxel 135 mg/m2 on day 1, 5-FU 500 mg/m2 on days 1-5, LV 200 mg/m2 on days 1-5 intravenous chemotherapy, cisplatin 75 mg/m2 on day 5, and HIPEC one month after surgery. It was repeated at 3 weeks intervals and at least two cycles administered. A total of 181 cycles of chemotherapy were administered (median, 4 cycles). The median disease free survival time of patients was 40.8 months. The median overall survival time was 48.0 months. The one-, two-, and three-year recurrence rates were 14.6%, 26.8%, and 46.3%, respectively. The main relapse patterns were remnant GC and metastases of retroperitoneal lymph nodes. The morbidity of grade 3 and 4 toxicities of myelosuppression, nausea/ vomiting were less than 10%. The side effects of grade 1 and 2 of hematologic toxicity, nausea and vomiting, abnormal function of liver, kidney or cardiac, fatigue and neurotoxicity were well tolerated. Cisplatin HIPEC combined with paclitaxel, 5-fluorouracil, and leucovorin intravenous chemotherapy regimen could improve the survival rate and decrease the postoperative recurrence of locally advanced GC.

    Objective. To evaluate the therapeutic effects of Disodium Pamidronate (Bonin) on bone pain in multiple myeloma. Method. 18 patients received only chemotherapy and 16 patients with addition of Bonin were compared. Result. The bone pain was significantly relieved both in chemotherapy alone group and in the combination group of Bonin with chemotherapy after treatment (P<0.01, as compared with before therapy). However, the effects of combination group were more dramatical than that of the other group (P<0.05). No obvious side-effects were observed except mild fever in one patient in the combination group. Conclusion. Bonin, as a safe and effective Bisphosphonates preparation, could relieve bone pain in multiple myeloma more effectively when combined with chemotherapy.

    2000-01-01

    Induction chemotherapy has been reported to be effective in treatment of locally advanced, borderline resectable, (Stage III), non small cell lung carcinoma (NSCLC). A logical extension of the indication for the induction chemotherapy may be to treat earlier stage resectable lung cancers (stages I and II) because the cure rate of the resectable lung cancers still remains poor and is below 60% except for stage I A. Thirty eight patients with a diagnosis of loco-regional NSCLC were treated with paclitaxel combination chemotherapy. Following two courses of induction chemotherapy, patients underwent surgical therapy whenever possible. There ten patients with stage I disease, four patients with stage II, 13 with stage IIIA, nine had stage IIIB, and two with stage IV. An overall response rate of 74% was observed. The response rate for 14 resectable patients (stage I and II) was 86%. The chemotherapy regimen was well tolerated and apart from one instance of anaphylaxis, no serious side effects were observed

Although the transurethral resection of bladder tumor (TURBT followed by intravesical chemotherapy is a conservative strategy for treatment of T1G3 bladder cancer, a relatively high risk of tumor recurrence and progression remains regarding the therapy. This study aimed to compare the efficacy of intravenous chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder cancer after TURBT surgery. Methods: We retrospectively reviewed the cases of 457 patients who were newly diagnosed with T1G3 bladder urothelial carcinoma between January 2009 and March 2014. After TURBT, 281 patients received intravesical chemotherapy alone, whereas 176 patients underwent intravesical chemotherapy in combination with intravenous chemotherapy. Tumor recurrence and progression were monitored periodically by urine cytology and cystoscopy in follow-up. Recurrence-free survival and progression-free survival of the two chemotherapy strategies following TURBT were analyzed. Univariable and multivariable Cox hazards analyses were performed to predict the prognostic factors for tumor recurrence and progression. Results: The tumor recurrence rate was 36.7% for patients who received intravesical chemotherapy alone after TURBT, compared with 19.9% for patients who received intravenous chemotherapy combined with intravesical chemotherapy after

    Treatment results of 49 patients (25, limited disease, LD, 24, extensive disease, ED) with small cell lung cancer were retrospectively analyzed. Fifteen patients received chemotherapy with Cyclophosphamide (CPM) and Vincristine (VCR) following thoracic radiotherapy (RT). Twenty-two patients were given induction chemotherapy with CPM, Adriamycin (ADM), and VCR and were followed by thoracic RT. Other chemotherapy consisted of CPM, VCR, Methotrexate, and ADM in 2 patients, 5-FU, CPM, Mitomycin C, and Toyomycin in 1 patient. The remaining 9 patients (2, LD, 7, ED) were treated with RT alone. The response rate was 80 % (64 % CR; 16 % PR) for LD patients and 33 % (4 % CR; 29 % PR) for ED patients (P < 0.001). The three-year survival (Kaplan-Meier's product) of all patients was 14 %, with a median survival time (MST) of 8 months. For patients with LD, the 3-year survival was 27 % (MST 15 months). Survival of patients with ED was 14 % at 1 year, 0 % at 2 year (MST 5.5 months). The difference between these figures was statistically significant (P < 0.0003). The 3-year survival and relapse-free survival for complete responders with LD were 43 % (MST 21 months) and 36 % (median CR duration, 11.5 months) respectively. Six of 16 complete responders with LD are alive and well at over 2 years. Local recurrence rate of the complete responders with LD was 28.8 %. None of the 7 complete responders given more than 48 Gy relapsed within the radiation field. We believe that the addition of thoracic RT to patients with LD is necessary for the control of the primary tumors and for long-term disease-free survival. (author)

    Forty-six patients with gliomas were introduced after surgery into a therapeutic programme of six cycles of combination chemotherapy with VM 26 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)

    34 patients operated on for malignant gliomas were successively treated by combination chemotherapy with VM 26 and CCNU and conventional radiation therapy with an average dosage of 5,800 rads, six months after surgery. The general and haematological tolerance of delayed irradiation after chemotherapy was satisfactory. Twelve patients developed neurological complications during or after irradiation. The complications were early in 10 cases, and delayed in 2. They were probably due to tumour growth in five cases, and secondary to irradiation in seven. In four of the seven cases the preradiation chemotherapy seemed to potentiate the radiation effect on the central nervous system. (author)

    1989-01-01

    During the period 1982-1988, 34 patients with advanced oral or oropharyngeal carcinoma were treated with radical radiation therapy combined with intraarterial chemotherapy. Five patients were clinically staged as Stage II,15 as Stage III, and 14 as Stage IV. For intraarterial chemotherapy, ACNU (25mg/body) or CDDP (20 mg/m 2 ) plus MMC (6 mg/m 2 ) was used. Overall, the complete response rate was 56%: it was independent of the site of carcinoma, clinical stage, and the kind of drugs. The two-year cumulative survival rate was 80% for Stage II, 56% for Stage III, and 61% for Stage IV. Side effects were not so severe as to continue with the withdrawal of chemotherapy. In view of the efficacy and safety, combined radiation therapy and intraarterial chemotherapy should be performed in the treatment of oral or oropharyngeal carcinoma. (N.K.)

    We studied in this series about histopathologic changes in radiotherapy of squamous cell carcinoma of head and neck. Then we recognized that radiotherapy combined with chemotherapy is useful for radioresistant squamous cell carcinoma. In this series, we studied about cancer of the tongue as one of the keratinizing squamous cell carcinoma and used Bleomycin as a chemotherapeutic drug. We commented as follows: 1. Radiotherapy combined with chemotherapy had benefit decreasing of a period for radium therapy. 2. Severs complication was not occurred in this series, then this combined therapy was useful for aged or handicapped patient. (author)

    The authors studied the effect of a chemo-/radiotherapy or radio-/chemotherapy on 52 cases of microcellular bronchial carcinoma, classification ''limited disease''. The survival curves were slightly better for the patients submitted to primary chemotherapy, but the difference was not statistically significant, and the curves coincided again after 18 months. 60 to 80% of the patients had no complaints or only unimportant complaints during more than half of their survival time. In 23 patients with ''extensive disease'' who received only a symptomatic therapy or a combined palliative chemotherapy, chemotherapy had a slightly better effect, but this was not statistically significant.

    Conclusions: Overall response rate, stable disease, and progressive disease, as well as 1-year survival rate in patients who received GEM + CIS, were superior to those treated with GEM alone. Combination chemotherapy with GEM and CIS may offer greater benefits in the treatment of pancreatic cancer than that of GEM alone although the combination group had higher hematological toxicities.

    Forty consecutive patients with small cell carcinoma of the lung were treated with chemotherapy, radiotherapy or both. Of 34 patients treated with chemotherapy, 24 were treated with combination chemotherapy, containing cyclophosphamide vincristine methotrexate and procarbazine, concurrent with small dose radiation therapy (500 cGy/5 fraction) as a chemosensitizer (COMPrt). The response rate to this regimen was 81 % (29 % complete) and the 2 year survival rate was 28.6 %. These results have been superior to other regimens and the toxicity was not see to be any higher. After completion of COMPrt regimen, 10 patients were treated with intrathoracic radiation therapy (average dose 3000 cGy) and 3 recieved surgical treatment. Radiation therapy improved the 2-year survival rate (42.2 %) when compared with those patients who received no radiation therapy (18.2 %). Three patients received surgical treatment were considered to be disease-free for 23, 17, and 9 months respectively, after induction of chemotherapy. (author)

    Research on anticancer therapies has advanced significantly in recent years. New therapeutic platforms that can further improve the health of patients are still highly demanded. We propose the idea of combining regular chemotherapy with radiation therapy to minimize side effects as well as increase drug-delivery efficiency. In this Focus Review, we seek to provide an overview of recent advances that can combine chemotherapy and radiotherapy. We begin by reviewing the current state of systems that can combine chemotherapy and gamma radiation. Among them, diselenide-containing polymers are highlighted as sensitive drug-delivery vehicles that can disassemble under gamma radiation. Then X-ray responsive materials as promising alternative systems are summarized, including X-ray responsive drug-delivery vehicles, prodrugs that can be activated by X-rays, and radiation-site-targeting systems. Finally, we describe strategies that involve phototherapies. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The successful treatment of a patient with bulky squamous cell carcinoma of the urethra using low dose preoperative radiation therapy and concurrent chemotherapy is described. Dramatic rapid tumor response facilitated surgical resection of the remaining microscopic disease. This clinical behavior is remarkably similar to that seen with squamous cell carcinoma of the anal canal and esophagus when a similar regimen is used. At the latter tumor sites the successful use of combination radiotherapy and chemotherapy has reduced the morbidity of subsequent surgery, and in selected cases has obviated the need for a radical operation. Further investigation of such combination treatment is warranted for urethral carcinoma

    Full Text Available Objective: To study the effect of cetuximab combined with paclitaxel + cisplatin neoadjuvant chemotherapy on esophageal cancer cell proliferation and invasion. Methods: A total of 62 patients with esophageal cancer who were treated in the hospital between January 2015 and December 2016 were collected and divided into control group and observation group according to random number table, with 31 cases in each group. Control group of patients received paclitaxel + cisplatin neoadjuvant chemotherapy + surgery, and observation group of patients accepted cetuximab combined with paclitaxel + cisplatin neoadjuvant chemotherapy + surgery. The differences in proliferation and invasion gene expression in the tumor tissue were compared between two groups of patients before and after chemotherapy. Results: Before chemotherapy, differences in proliferation and invasion gene expression in tumor tissue were not statistically significant between two groups of patients. After chemotherapy, proproliferation genes FOXA1, ABCE1, USP39 and Nestin mRNA expression in tumor tissue of observation group were significantly lower than those of control group; anti-proliferation genes PETN, KLF4, TSLC1 and AnnexinA2 mRNA expression were significantly higher than those of control group; pro-invasion genes γ-synuclein, CXCR4 and Snail mRNA expression were significantly lower than those of control group; anti-invasion genes CIAPIN1, Fez and Lrig1 mRNA expression were significantly higher than that of control group. Conclusions: Cetuximab combined with paclitaxel + cisplatin neoadjuvant chemotherapy can effectively inhibit the malignant degree of esophageal cancer cells and inhibit its proliferation and invasion.

    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

    A new multimodality therapy, radio-hyperthermo-chemotherapy, has been performed in a total of 31 pancreatic cancer patients with the purpose of improving treatment outcome. Combination of hyperthermia and chemotherapy was given as a pre-irradiation therapy in 7 resectable cancer patients. Among 24 unresectable cancer patients, 17 had irradiation in combination with hyperthermia and chemotherpay. Although both degeneration and necrosis of cancer cells were observed in all resectable cases at biopsy, these were not predictive of a better outcome. Of evaluable 17 patients with unresectable cancer, tumor regression was observed in 5 (29.4%). Although 22 patients had pain before therapy, 8 and 5 patients had remarkable and moderate pain relief, respectively, with therapy. Performance status was improved in 7 patients (29.2%). Survival rate at 12 months was still low (8.3%). However, the radio-hyperthermo-chemotherapy appears to help in increasing the quality of life in view of pain relief. (N.K.)

    Full Text Available Minoo Robati, David Holtz, Charles J DuntonDepartment of Obstetrics and Gynecology, Main Line Gynecologic Oncology, Lankenau Hospital, Wynnewood, PA, USAAbstract: Treatment of advanced, recurrent or persistent cervical cancer includes radiotherapy and chemotherapy. Radiation has been the primary treatment modality for locoregionally advanced cervical cancer. Concomitant systemic cisplatin chemotherapy and radiation have shown high response rates with improvements in durable remissions and overall survival. Cisplatin has been the standard medication for the treatment of advanced cervical cancer. Combinations with other chemotherapeutic agents have been the subject of clinical trials with varying results. The toxicity of combination chemotherapy and tolerability of patients are other factors that should be considered in the management of patients with advanced disease. Recently topotecan, in combination with cisplatin, achieved increased response and overall survival rates without further compromising the patients’ quality of life. This review focuses on the mechanism of action and toxicities of topotecan, as well as its role as a radio-sensitizer and chemotherapeutic agent in the management of advanced, recurrent, or persistent cervical cancer. Other combination modalities and dosages are also discussed.Keywords: topotecan, combination chemotherapy, advanced cervical cancer

    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

    To observe the effects of MVP chemotherapy combined with concurrent radiotherapy for stage IIIB-IV non-small cell lung cancer. Sixty-two patients with stage IIIB-IV non-small cell lung cancer were randomized into two groups, concurrent radiochemotherapy group and MVP che-motherapy group. All patients in two groups were treated with MVP regimen (mitomycin C 6 mg/m² on day 1, vindesine 2 mg/m² on days 1, 8, and cisplatin 80-100 mg/m²). Patients in concurrent radiochemotherapy group received concurrent radiotherapy (46-56 Gy in 5-6 weeks). All patients received 2-4 cycles of MVP chemotherapy. The response rate was 48.4% and 19.4% in concurrent radiochemotherapy group and MVP group respectively (P MVP group.. The results show that efficacy of MVP chemotherapy combined with concurrent radiotherapy is significantly higher than that of MVP chemotherapy alone for advanced non-small cell lung cancer.

    The purpose of this study was to identify drugs that can enhance radioresponse of murine hepatocarcinoma. C3H/HeJ mice bearing 8 mm tumors of murine hepatocarcinoma, HCa-l, were treated with 25 Gy radiation and one of the following drugs: 5-Fu, 150 mg/kg; adriamycin, 8 mg/kg; cisplatin, 6 mg/kg; paclitaxel, 40 mg/kg; and gemcitabine, 50 mg/kg. Tumor response to the treatment was determined by tumor growth delay assay and by enhancement factor. Apoptotic level was assessed in tissue sections. Expression of regulating molecules was analyzed by western blotting for p53, 8c1-2, Sax, Bel-XL, Bd-XS, and p21 WAF1/CIP1 . Among the drugs tested, only gemcitabine enhanced the antitumor effect of radiation, with enhancement factor of 1.6. Induction of apoptosis by a combination of gerncitabine and radiation was shown as only additive level. In analysis of radiation-induced expression of regulating molecules, the most significant change by combining gemcitabine was activation of p21 WAF1/CIP1 . Gemcitabine is the first drug showing an enhancement of radioresponse in murine hepatocarcinoma, when combined with radiation. The key element of enhancement is thought to be p21 WAF1/CIP1

    The purpose of this study was to identify drugs that can enhance radioresponse of murine hepatocarcinoma. C3H/HeJ mice bearing 8 mm tumors of murine hepatocarcinoma, HCa-l, were treated with 25 Gy radiation and one of the following drugs: 5-Fu, 150 mg/kg; adriamycin, 8 mg/kg; cisplatin, 6 mg/kg; paclitaxel, 40 mg/kg; and gemcitabine, 50 mg/kg. Tumor response to the treatment was determined by tumor growth delay assay and by enhancement factor. Apoptotic level was assessed in tissue sections. Expression of regulating molecules was analyzed by western blotting for p53, 8c1-2, Sax, Bel-XL, Bd-XS, and p21{sup WAF1/CIP1}. Among the drugs tested, only gemcitabine enhanced the antitumor effect of radiation, with enhancement factor of 1.6. Induction of apoptosis by a combination of gerncitabine and radiation was shown as only additive level. In analysis of radiation-induced expression of regulating molecules, the most significant change by combining gemcitabine was activation of p21 {sup WAF1/CIP1}. Gemcitabine is the first drug showing an enhancement of radioresponse in murine hepatocarcinoma, when combined with radiation. The key element of enhancement is thought to be p21{sup WAF1/CIP1}.

    The combined effects of radiation and drugs on the fine vasculature of mouse liver were investigated by microangiography. The fine vasculature of the liver showed dilatations one day after 1000 rad of irradiation to the liver. The fine vasculature of the liver showed marked dilatations and slight extravasations one day after 1000 rad of irradiation to the whole body. The fine vasculature of the liver showed dilatations and partial narrowings after the administration of BLM, 2mg/kg/day ip for 5 days. The combined effects of BLM and radiation was greater than that with radiation alone. The fine vasculature of the liver showed marked dilatations and slight extravasation after the administration of BLM, 2mg/kg/day ip for 5 days and MMC 2mg/kg ip on day 6. This findings is about the same as that after the administration of BLM and 1000 rad of irradiation. The administration of urokinase did not diminish the effects of radiation on the fine vasculature of the liver. The administration of YM-08310 diminished the effects of irradiation on the fine vasculature of the liver. (author)

    Combined chemo and photothermal therapy in in vitro testing has been achieved by means of multifunctional nanoparticles formed by plasmonic gold nanoclusters with a protecting shell of porous silica that contains an antitumor drug. We propose a therapeutic nanoplatform that associates the optical activity of small gold nanoparticles aggregates with the cytotoxic activity of 20(S)-camptothecin simultaneously released for the efficient destruction of cancer cells. For this purpose, a method was used for the controlled assembly of gold nanoparticles into stable clusters with a tailored absorption cross-section in the vis/NIR spectrum, which involves aggregation in alkaline medium of 15 nm diameter gold colloids protected with a thin silica layer. Clusters were further encapsulated in an ordered homogeneous mesoporous silica coating that provides biocompatibility and stability in physiological fluids. After internalization in 42-MG-BA human glioma cells, these protected gold nanoclusters were able to produce effective photothermolysis under femtosecond pulse laser irradiation of 790 nm. Cell death occurred by combination of a thermal mechanism and mechanical disruption of the membrane cell due to induced generation of micrometer-scale bubbles by vaporizing the water inside the channels of the mesoporous silica coating. Moreover, the incorporation of 20(S)-camptothecin within the pores of the external shell, which was released during the process, provoked significant cell death increase. This therapeutic model could be of interest for application in the treatment and suppression of non-solid tumors.

    A report is given on 160 patients suffering from ovarian carcinomas the stages which were exactly determined by TNM classification. 32 patients had tumors of the stages T1-T3, 128 patients had tumors of the stage T4. All T3 subgroups showed favorable results after radical surgery and a postoperative combination of radiotherapy and selective cytostatic chemotherapy. The therapy plans including radiotherapy had more advantages than those without radiotherapy. Furthermore, the cytostatic treatment was more successful after a chemotherapy resistance test than after blind administration of cytostatic drugs. (orig.) [de

    Objective: To retrospectively analyze the effectiveness of transarterial infusion chemotherapy of gemcitabine and 5-fluorouracil in advanced pancreatic carcinoma. Methods: Twenty-two patients with advanced pancreatic carcinoma were treated with transarterial infusion chemotherapy. Gemcitabine and 5-fluorouracil was administered to the patients via an interarterial catheter. Then the tumor response rate and clinical benefit were observed. Results: A clinical benefit was obtained in 8 patients (36.4%). The tumor response rate was 13.6%. Median survival for all the patients was 6.1 months. Median time to tumor progression was 2.9 months. Conclusion: Transarterial infusion chemotherapy with a combination of gemcitabine and 5-fluorouracil appears to have good clinical benefit and may prolong the survival time of patients with advanced pancreatic carcinoma

    The combination of radiotherapy and chemotherapy has improved the results of treatment of certain malignant tumours. However, during both experimental investigations and clinical treatment, a number of severe side effects have been observed, during as well as some time after the administration, especially with use of actinomycin and adriamycin. Also the possibility exists that more secondary tumours are induced as the consequence of combination therapy. (Auth.)

    A total of 9 patients with invasive bladder cancer (T2b, n=2; T3a, n=0; T3b, n=3; T4, n=4) were treated with intra-arterial cisplatin (CDDP) and pirarubicin (THP)-doxorubicin (ADM), in combination with external radiotherapy. Clinical response was as follows: complete response (CR) was obtained in 3 patients, partial response (PR) in 2 patients, no change (NC) in 3 patients and no progressive disease (PD). One patient died during the treatment because of pneumonia caused by myelosuppression and overall response rate was 62.5%. Total cystectomy was performed for 4 patients after chemo-radiotherapy. Overall survival rate was 75.0% for 1-year, 62.5% for 2-year, and 41.7% for 5-year. In group with cystectomy survival rate was 100% for 1-year, 100% for 2-year, and 50.0% for 5-year. In group without cystectomy, 50.0% for 1-year, and 25.0% for 2-year. Overall no recurrence rate was 87.5% for 6-months, 58.3% for 1-year, and 58.3% for 5-year. Main side effects were myelosuppression, appetite loss, diarrhea, thigh pain and contracted bladder. (author)

    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).

    Background Regorafenib has been demonstrated as effective in refractory metastatic colorectal cancer. Combination use with chemotherapy has not been reported. We examined the efficacy and safety of adding chemotherapy to Regorafenib for the treatment of metastatic colorectal cancer(mCRC) patients. Methods We recruited mCRC patients at our institute who received either regorafenib monotherapy or regorafenib in combination with other chemotherapies. All patients had received chemo and target therapies and presented with disease progression before regorafenib treatment. The primary end point was overall survival. Findings Between September1, 2015 and May 31, 2017, 100 mCRC patients at our institute received regorafenib treatment. 39 patients were excluded due to poor performance, lack of timely treatment, or inadequate clinical data. A total of 34 patients received regorafenib combined with other chemotherapies, and 27 patients received regorafenib alone. Median follow up time was 10.4 and 6.1 months, respectively. The primary end point of median OS was higher in the combination group than in the single use group (20.9m vs 10.3m, p = 0.015). The most frequent adverse events were hand-foot skin reactions(16[47.1%]vs 12[44.4%]), fatigue(6[17.6%] vs 7[25.9%]), gastrointestinal discomfort (7[20.6%] vs 6[22.2%]), neutropenia (4[11.8%] vs 1[3.7%]), diarrhea(4[11.8%] vs 1[3.7%]), and mucositis(5[14.7%] vs 1[3.7%]). Conclusion The present study showed the efficacy and side effects of regorafenib combination treatment. Superiority in median OS and median PFS was noted in the combination group. The sampling difference between the study and observation groups effects justifies the comparison. Further clinical evidence of combination therapy efficacy is pending future studies. PMID:29304109

    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.

    Between May 1986 and April 1994, 15 patients with advanced or recurrent gynecological cancer were treated with combined therapy of hyperthermia and irradiation or chemotherapy at UOEH Hospital. Initial cases were treated by hyperthermia combined with irradiation in 4 and with chemotherapy in 2. Recurrent 9 cases were treated by hyperthermia combined with chemotherapy or by hyperthermia alone. Radiotherapy was given in a conventional way 5 fractions per week and hyperthermia was performed using RF capacitive heating equipment, Thermotron RF-8, once or twice a week. Intratumoral temperature was measured by thermocouple inserted into the tumor and kept at 42-44degC for 30-40 minutes. Complete response (CR) and partial response (PR), defined as 50% or more regression, was obtained in 8/15 (53%). Response rates (CR+PR/all cases) were good in initially treated cases (5/6, 83%), irradiated cases (7/8, 88%) and cases hearted over 42degC (7/9, 78%). Combined therapy of hyperthermia and radiotherapy seemed to be useful for controlling advanced gynecological cancers. (author)

    Twenty-two patients with limited unresectable squamous cell lung cancer were treated with 6 courses of combination chemotherapy consisting of cyclophosphamide, adriamycin, cisplatin, and bleomycin (CAP-Bleo) and short-course thoracic irradiation started after the first 4 weeks of chemotherapy. Of 20 patients with visible tumor who were treated with 4 weeks of chemotherapy alone, 10 (50%) had a tumor regression in that 4 week period and 10 did not. Those patients with tumor regression had significantly better progression free and overall survivals than did patients with no chemotherapy regressions (medians of 258 days vs. 136 days and 356 days vs. 150 days respectively). The original bleomycin dose had to be reduced by 50% primarily because of excessive radiation esophagitis that has not been reported with use of either the CAP regimen or bleomycin along in conjunction with thoracic irradiation. An initial chemotherapy regression seems to be a good prognosticator for progression-free and overall survival in patients with limited squamous cell lung cancer treated with combined chemotherapy and radiotherapy

    We evaluate the feasibility and efficacy of combination chemotherapy including single intraperitoneal( IP)administration of paclitaxel(PTX), followed by triplet chemotherapy(PTX, cisplatin[CDDP]and S-1: PCS)for CY1P0 gastric cancer. First of all, we performed staging laparoscopy and confirmed CY1P0, and secondary, administrated PTX intraperitoneally. Thirdly, patients received PCS chemotherapy for 2 courses. After antitumor effect had been confirmed, we performed second look laparoscopy. In the case of CY0P0, we performed gastrectomy with D2 lymph nodes dissection. Total 4 patients were enrolled. Grade 3 leukopenia and neutropenia were observed in one patient while intraperitoneal and systemic-chemotherapy. One patients showed PR and 3 patients showed SD. All patients underwent second look laparoscopy. CY0P0 was observed in all patients and gastrectomy with D2 dissection was performed for all patients. Postoperative complications were observed in 2 patients. Two patients were still alive without recurrence, while the remaining 2 had died of liver metastasis and #16 LN metastasis. Combination chemotherapy including single IP PTX followed by PCS systemic-chemotherapy for CY1P0 gastric cancer is feasible and efficient.

    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.)

    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)

    The literature on combined treatment with radiation and cytotoxic drugs in experimental tumours and normal tissues of laboratory animals is reviewed in the context of the four previously proposed mechanisms whereby a therapeutic advantage might be gained. There is evidence for strong time-dependent processes occurring in some normal tissues. In tumours, the evidence is much weaker and there is considerable disparity among experimental tumours in optimum timing. This review leads to the conclusion that the clinical use of drug-radiation combinations should not be based on an anticipated beneficial interaction; gain will most probably come from the best radiotherapy and the best chemotherapy given as far as possible independently. Deleterious interactions can be reduced by allowing a gap of some weeks between chemotherapy and radiotherapy and by avoiding drugs that are known to enhance radiation damage to the normal tissues that are irradiated. 131 refs.; 4 figs.; 5 tabs

    The standard treatment for ovarian cancer is chemotherapy with 2 drugs (taxanes and platinum drugs). However, the traditional combination of the 2 drugs has many adverse effects (AEs) and the cancer cells will quickly become resistant to the drugs. Apatinib is a small-molecule antiangiogenic agent which has shown promising therapeutic effects against diverse tumor types, but it still remains unknown whether apatinib has an antitumor effect in patients with ovarian cancer. Herein, we present a successfully treated case of ovarian cancer using chemotherapy and apatinib, in order to demonstrate the effectiveness of this new combined regimen in ovarian cancer. A 51-year-old Chinese woman presented with ovarian cancer >4.5 years. The disease and the cancer antigen 125 (CA-125) had been controlled well by surgical treatment and following chemotherapy. However, the drugs could not control the disease anymore as the CA-125 level was significantly increasing. Ovarian cancer. The patient was treated with apatinib combined with epirubicin. Apatinib was administered orally, at an initial daily dose of 500 mg, and was then reduced to 250 mg qd after the appearance of intolerable hand-foot syndrome (HFS) and oral ulcer. Then, the oral ulcer disappeared and the HFS was controlled by dose adjustment, oral vitamin B6, and hand cream application. The CA-125 reverted to the normal value after treatment with the new regimen. Magnetic resonance imaging showed that the original tumor lesions had disappeared. Apatinib monotherapy as maintenance therapy was then used to successfully control the cancer with a complete response. Our study is the first, to our knowledge, to report the therapeutic effects of apatinib and epirubicin on ovarian cancer. Apatinib combined with chemotherapy and apatinib monotherapy as maintenance therapy could be a new therapeutic strategy for ovarian cancer, especially adenocarcinomas.

    Heat shock proteins (HSPs) are molecular chaperones subdivided into several families based on their molecular weight. Due to their cytoprotective roles, these proteins may help protect cancer cells against chemotherapy-induced cell death. Investigation into the biologic activity of HSPs in a variety of cancers including primary bone tumors, such as osteosarcoma (OSA), is of great interest. Both human and canine OSA tumor samples have aberrant production of HSP70. This study assessed the response of canine OSA cells to inhibition of HSP70 and GRP78 by the ATP-mimetic VER-155008 and whether this treatment strategy could sensitize cells to doxorubicin chemotherapy. Single-agent VER-155008 treatment decreased cellular viability and clonogenic survival and increased apoptosis in canine OSA cell lines. However, combination schedules with doxorubicin after pretreatment with VER-155008 did not improve inhibition of cellular viability, apoptosis, or clonogenic survival. Treatment with VER-155008 prior to chemotherapy resulted in an upregulation of target proteins HSP70 and GRP78 in addition to the co-chaperone proteins Herp, C/EBP homologous transcription protein (CHOP), and BAG-1. The increased GRP78 was more cytoplasmic in location compared to untreated cells. Single-agent treatment also revealed a dose-dependent reduction in activated and total Akt. Based on these results, targeting GRP78 and HSP70 may have biologic activity in canine osteosarcoma. Further studies are required to determine if and how this strategy may impact the response of osteosarcoma cells to chemotherapy.

    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.

    There are sound radiobiologic and suggestive clinical rationale for superfractionating the radiotherapeutic regimens employed for the therapy of rapidly growing malignancies. Oat cell carcinoma of the bronchus is such a tumor. The authors report their experience combining aggressive systemic combination chemotherapy with supperfractionated radiotherapy for the treatment of limited oat cell carcinoma of the bronchus. Overall, patient tolerance was satisfactory and a complete remission rate of 74% was achieved. It remains to be proven, in a prospective randomized fashion, whether this approach is superior to current conventional management

    Combined photothermo-chemotherapy is a new strategy for cancer treatment which improves the therapeutic outcome by synergistic effects of both therapies. Here, we presented a multifunctional gold nanoshell that exhibited excellent photothermal conversion and delivered the hydrophobic chemotherapy drug, SN-38. The positively charged SN-38-loaded PDMA-PCL micelles were decorated with a gold layer by in situ reduction of chloroauric acid on the surface of micelles. Scanning and transmission electron microscopy images proved micelles were successfully decorated and the resulting gold nanoshells had a spherical morphology with a narrow size distribution. The synthesized gold nanoshells displayed a broad surface plasmon resonance peak in the near-infrared wavelength region and a great photothermal conversion ability. After pegylation, gold nanoshells were stable in biological media and appeared highly biocompatible in the absence of laser irradiation. Upon near-infrared laser irradiation, incident energy was converted into heat by gold nanoshells on SN-38-loaded micelles (SN-38@pGNS), which causes local temperature increase and triggers the release of encapsulated drug. Compared to SN-38, SN-38-loaded micelles, or laser with drug-free gold nanoshells alone, combined photothermo-chemotherapy using SN-38@pGNS with laser irradiation killed colorectal cancer cells with higher efficacy in vitro and demonstrated significant tumor suppression in vivo, suggesting that gold nanoshells on drug-loaded micelles delivered SN-38 and photothermal therapy in synergistic actions and might be a potential candidate for future colorectal cancer therapy.

    Purpose: To assess the efficacy of balloon dilation combined with chemotherapy and/or radiation therapy for palliation of dysphagia due to malignant esophagogastric junction strictures. Methods: Fluoroscopically guided balloon dilation was attempted in 20 patients. The causes of strictures were gastric adenocarcinoma (n = 10) and esophageal squamous cell carcinoma (n = 10). Scheduled chemotherapy and/or radiation therapy followed balloon dilation in all patients. Results: There were no technical failures or major complications. After balloon dilation, 15 (75%) patients showed improvement of dysphagia. No patient complained of reflux esophagitis during the follow-up period. Among the 15 patients, seven needed no further treatment for palliation of dysphagia until their deaths. The remaining eight patients underwent repeat balloon dilation(n = 4) or stent placement (n = 4)3-43 weeks (mean 15 weeks) after the initial balloon dilation because of recurrent dysphagia. Conclusion: Balloon dilation combined with chemotherapy and/or radiation therapy seems to be an easy and reasonably effective palliative treatment for malignant esophagogastric strictures

    Thirty-five patients with advanced ovarian cancer have received, as salvage therapy, irradiation consisting of 30 Gy to the entire abdominal contents with partial liver/kidney shielding and boosts to 42 and 51 Gy for the paraaortic/diaphragmatic and pelvic regions, respectively. These patients had received 6 to 25 cycles (median, 11 cycles) of prior combination chemotherapy (included cisplatin in 30), with second-look laparotomy performed in 33; 24 (68%) had three or more laparotomies. Acute gastrointestinal toxicity was generally mild. Significant hematologic toxicity (leukocytes less than 2000/mm3; or platelets less than 100,000/mm3) was seen in 19 (54%); platelet suppression occurred in 18 of these 19. Nine patients failed to complete the prescribed course of therapy; in seven, this was secondary to hematologic toxicity. Amount of prior chemotherapy and advanced age correlated with degree of hematologic toxicity. Five patients without evidence of disease (laparotomy confirmed) have developed treatment-related bowel obstruction. No other chronic toxicity of clinical significance has been observed. Seven patients have developed bowel obstruction associated with progressive neoplasm. Irradiation was well tolerated symptomatically, but hematologic toxicity associated with prior chemotherapy prevented its completion in 20% of patients. Clinical manifestations of radiation bowel toxicity have been moderate to date and should be interpreted in the context of the aggressive combined modality program

    Purpose: To compare the efficacy of intra-arterial chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder transitional cell carcinoma (BTCC) followed by bladder-preserving surgery. Materials and Methods: Sixty patients with T1G3 BTCC were randomly divided into two groups. After bladder-preserving surgery, 29 patients (age 30-80 years, 24 male and 5 female) received intra-arterial chemotherapy in combination with intravesical chemotherapy (group A), whereas 31 patients (age 29-83 years, 26 male and 5 female) were treated with intravesical chemotherapy alone (group B). Twenty-nine patients were treated with intra-arterial epirubicin (50 mg/m{sup 2}) + cisplatin (60 mg/m{sup 2}) chemotherapy 2-3 weeks after bladder-preserving surgery once every 4-6 weeks. All of the patients received the same intravesical chemotherapy: An immediate prophylactic was administered in the first 6 h. After that, therapy was administered one time per week for 8 weeks and then one time per month for 8 months. The instillation drug was epirubicin (50 mg/m{sup 2}) and lasted for 30-40 min each time. The end points were tumour recurrence (stage Ta, T1), tumour progression (to T2 or greater), and disease-specific survival. During median follow-up of 22 months, the overall survival rate, tumour-specific death rate, recurrence rate, progression rate, time to first recurrence, and adverse reactions were compared between groups. Results: The recurrence rates were 10.3 % (3 of 29) in group A and 45.2 % (14 of 31) in group B, and the progression rates were 0 % (0 of 29) in group A and 22.6 % (7 of 31) in group B. There was a significant difference between the two groups regarding recurrence (p = 0.004) and progression rates (p = 0.011). Median times to first recurrence in the two groups were 15 and 6.5 months, respectively. The overall survival rates were 96.6 and 87.1 %, and the tumour-specific death rates were 0 % (0 of 29) and 13.5 % (4 of 31

    Full Text Available Abstract We report here a 44-year-old Moroccan man with resectable gastric adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2 by immunohistochemistry who was treated with trastuzumab in combination with chemotherapy in perioperative setting. He received 3 cycles of neoadjuvant chemotherapy consisting of trastuzumab, oxaliplatin, and capecitabine. Afterwards, he received total gastrectomy with extended D2 lymphadenectomy without spleno-pancreatectomy. A pathologic complete response was obtained with a combination of trastuzumab and oxaliplatin and capecitabine. He received 3 more cycles of trastuzumab containing regimen postoperatively. We conclude that resectable gastric carcinoma with overexpression of the c-erbB-2 protein should ideally be managed with perioperative combination of trastuzumab with chemotherapy. Further research to evaluate trastuzumab in combination with chemotherapy regimens in the perioperative and adjuvant setting is urgently needed.

    Tumor drug resistance significantly limits the success of chemotherapy in the clinic. Tumor cells utilize multiple mechanisms to prevent the accumulation of anticancer drugs at their intracellular site of action. In this study, we investigated the anticancer efficacy of doxorubicin in combination with photodynamic therapy using methylene blue in a drug-resistant mouse tumor model. Surfactant-polymer hybrid nanoparticles formulated using an anionic surfactant, Aerosol-OT (AOT), and a naturally occurring polysaccharide polymer, sodium alginate, were used for synchronized delivery of the two drugs. Balb/c mice bearing syngeneic JC tumors (mammary adenocarcinoma) were used as a drug-resistant tumor model. Nanoparticle-mediated combination therapy significantly inhibited tumor growth and improved animal survival. Nanoparticle-mediated combination treatment resulted in enhanced tumor accumulation of both doxorubicin and methylene blue, significant inhibition of tumor cell proliferation, and increased induction of apoptosis. These data suggest that nanoparticle-mediated combination chemotherapy and photodynamic therapy using doxorubicin and methylene blue has significant therapeutic potential against drug-resistant tumors.

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

    Directory of Open Access Journals (Sweden)

    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.

    In this study, we investigated an effective strategy of treatment for unresectable gallbladder cancer (GBC) by the retrospective analysis of prognostic factors and anti-tumor therapies, especially combination therapy of arterial infusion chemotherapy and radiation therapy (AI+PT). Forty-three patients with unresectable GBC were enrolled, and prognostic factors were investigated by multivariate analysis using a proportional hazard model. In addition, we examined the indication and after-therapy by analyzing the each factor cumulative survival rates and anti-tumor effect about the AI + RT group (n=24). AI + RT and the responders to the first-line therapy were significant prognostic factors. In AI + RT group, median survival time, progression-free survival and the 1-year survival rate, the response and disease control rates was 15.5 months, 7.1 months, 62.5%. 54.2% and 95.8%, respectively; which suggested prolonged survival and high anti-tumor effect. Cumulative survival rate was significantly shorter in cases with distant metastasis except liver metastases, and has been tendency to extend in the group who underwent systemic chemotherapy as after-therapy. The treatment strategy, using the Al + RT as first-line with the systemic chemotherapy as after-therapy, suggested contribute to the prolonged survival in locally advanced and liver metastases cases of GBC.

    Over the past four years, 27 patients with recurrent tumors of the head and neck region have been treated with chemotherapy. The regimens used were BCMF (bleomycin 15 mg i.v. for 3 days, cyclophosphamide 500 mg i.v., methotrexate 50 mg i.v. and 5-fluorouracil 500 mg i.v.) and CMU (cyclophosphamide 350 mg/m 2 i.v., methotrexate 30 mg/m 2 i.v. and UFT 600 mg p.o. for 14 days). Of the 27 patients, eight were treated with combined radiation and chemotherapy, and either CR or PR was obtained. Nineteen patients were treated with chemotherapy alone, for which the response (CR + PR) rates were 8 % (1/12) for BCMF and 43 % (3/7) for CMU, respectively. No serious toxicities were observed as a result of these regimens. It was thus demonstrated that the CMU regimen was of great value in terms of improved response and minor toxicity in the treatment of head and neck tumors. (author)

    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)

    Despite much more intense treatment in the 3 - D group, the acute toxicity was not significantly different between the two groups. A complete tumor regression was observed in 41 % of the patients in the 2- D group and 58 % in the 3- D group. however, given the short follow-up and the relatively limited number of patients in the 3 - D group, conclusions regarding tumor response need further investigations. The use of 3 - D conformal radiotherapy allowed to increase the dose intensity of re irradiation combined with chemotherapy, without increasing deleterious effect. (N.C.)

    The object of this study is to evaluate the efficacy of preoperative chemotherapy combined with radiation therapy for bladder cancer. A total of 44 patients with bladder cancer were treated by preoperative chemotherapy combined with radiation therapy between October, 1981 and December, 1986. Clinical stages included 4 patients in Ta, 25 in T1, 11 in T2, and 4 in T3. Each patient was treated twice with 15 gray of radiation to the small pelvic cavity and a chemotherapy combination of adriamycin, cis-platinum, tegaful, and peplomycin. The average observation time after the therapy was 83 month, with the maximum being 146 months. Complete remission was included in 5 patients, partial remission in 27, and no change in 12. Thus, the overall effective rate was 72.8%. Operations, selected by the results of the preoperative therapy, included transurethral resection on 28 patients, transurethral fulguration on 2, partial cystectomy on 4, resection of tumor on 4, and total cystectomy on 3. Operations were not performed on 2 patients and not allowed on 1 patient. The outcome during the long-term follow-up included cancer related deaths in 4 patients, and death resulting from other disorders in 9. The 5-year survival rates for superficial and invasive bladder cancer were 92.4%, and 83.9%, respectively. The 10-year survival rates for superficial and invasive bladder cancer were also 92.4% and 83.9%, respectively. The 3-year and 5-year non-recurrence rates for superficial bladder cancer were 75.8%, and 66.9% respectively, according to the Kaplan-Meier method. On the other hand, the 3-year and 5-year non-recurrence rates for invasive bladder cancer were both 73.8%. During the follow-up between 9 and 11 years, 3 upper tract tumor were diagnosed (2 ureteral cancer, and 1 renal pelvic cancer). We concluded that preoperative chemotherapy combined with radiation therapy may be effective for the treatment of bladder cancer. (author)

    Treatment was studied of oro-facial epidermoid carcinoma by combined chemo- and radiotherapy and eventual surgery. Cytostatic drugs were applied intraarterially. After a monocytostatic treatment trial with Methotrexate (MTX), a combined cytostatic program was developed alternating two cytostatic drugs, viz., MTX and Bleomycin (BLM). The usefulness of chemotherapy and its inclusion in the treatment of epidermoid carcinoma in the oro-facial region was found justified for combined therapy. The selected intraarterial administration, however, is not suitable for routine application. For this reason, the combination irradiation or surgical therapy with chemotherapy was adopted.

    Drug resistance limits the success of many anticancer drugs. Reduced accumulation of the drug at its intracellular site of action because of overexpression of efflux transporters such as P-glycoprotein (P-gp) is a major mechanism of drug resistance. In this study, we investigated whether photodynamic therapy (PDT) using methylene blue, also a P-gp inhibitor, can be used to enhance doxorubicin-induced cytotoxicity in drug-resistant tumor cells. Aerosol OT (AOT)-alginate nanoparticles were used as a carrier for the simultaneous cellular delivery of doxorubicin and methylene blue. Methylene blue was photoactivated using light of 665 nm wavelength. Induction of apoptosis and necrosis following treatment with combination chemotherapy and PDT was investigated in drug-resistant NCI/ADR-RES cells using flow cytometry and fluorescence microscopy. Effect of encapsulation in nanoparticles on the intracellular accumulation of doxorubicin and methylene blue was investigated qualitatively using fluorescence microscopy and was quantitated using HPLC. Encapsulation in AOT-alginate nanoparticles significantly enhanced the cytotoxicity of combination therapy in resistant tumor cells. Nanoparticle-mediated combination therapy resulted in a significant induction of both apoptosis and necrosis. Improvement in cytotoxicity could be correlated with enhanced intracellular and nuclear delivery of the two drugs. Further, nanoparticle-mediated combination therapy resulted in significantly elevated reactive oxygen species (ROS) production compared to single drug treatment. In conclusion, nanoparticle-mediated combination chemotherapy and PDT using doxorubicin and methylene blue was able to overcome resistance mechanisms and resulted in improved cytotoxicity in drug-resistant tumor cells.

    Red blood cells (RBCs)-based vesicles have been widely used for drug delivery due to their unique advantages. Intact RBCs contain a large amount of oxyhemoglobin (oxyHb), which can assist with photodynamic therapy (PDT). Indocyanine green (ICG), a photosensitizer both for photothermal therapy (PTT) and PDT, shows potent anticancer efficacy when combined with chemotherapeutic drug doxorubicin (DOX). In this study, we prepared nanoscaled RBCs (RAs) containing oxyHb and gas-generating agent ammonium bicarbonate (ABC) for co-loading and controlled release of ICG and DOX, thus hoping to achieve synergistic effects of PTT/PDT and chemotherapy against breast cancer. Compared to free ICG, ICG and DOX co-loaded RAs (DIRAs) exhibited nearly identical PTT efficiency both in vitro and in vivo, but meanwhile their PDT efficiency was enhanced significantly. In mouse breast cancer cells, DIRAs significantly inhibited cell growth and induced cell apoptosis after laser irradiation. In breast tumor-bearing mice, intratumoral injection of DIRAs and followed by local laser irradiation almost completely ablated breast tumor and further suppressed tumor recurrence and metastasis. In conclusion, this biomimetic multifunctional nanosystem can facilitate breast cancer treatment by combining PTT/PDT and chemotherapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To evaluate the treatment outcomes of patients with locally advanced rectal cancer treated with preoperative concurrent chemoradiotherapy (CCRT) or combined chemotherapy together with radiotherapy (CMTRT) without surgery. A total of 84 patients with locally advanced rectal adenocarcinoma (stage II or III) between January 1st, 2003 and December 31st, 2013 were enrolled, 48 treated with preoperative CCRT (Gr.I) and 36 with combined chemotherapy and radiotherapy (CMTRT) without surgery (Gr.II). The chemotherapeutic agents used concurrent with radiotherapy were either 5fluorouracil short infusion plus leucovorin and/or capecitabine or 5fluorouracil infusion alone. All patients received pelvic irradiation. There were 5 patients (10.4%) with a complete pathological response. The 3 yearoverall survival rates were 83.2% in Gr.I and 24.8 % in Gr.II (prectal cancer demonstrated that in preoperative CCRT a sphincter sparing procedure can be performed. The results of treatment with preoperative CCRT for locally advanced rectal cancer showed comparable rates of overall survival and sphincter sparing procedures as compared to previous studies.

    The menstrual cycle, pregnancies, and offspring were evaluated before and after initial combined radiation (RT) and chemotherapy with thiotepa, vinblastine, vincristine, procarbazine, and prednisone (TVPP), in 34 women between the ages of 18 and 44 (median 26.5 years) treated for Stage II and Stage III Hodgkin's disease. The median range of follow-up is 83.1 months (range 40.5-140). After therapy 94.1% (32/34) continued to menstruate. Two of the four patients over the age of 35 ceased to menstruate. All patients under the age of 35 continued to menstruate (30/30). Age at the time of diagnosis was the only factor affecting change in menses with a significant probability (p = .001) that women greater than 30 years of age will experience some change in menstrual pattern. Seventeen pregnancies occurred in 12 women after therapy; 2 had 4 elective abortions; 10 delivered 12 children with normal physical development; 1 will deliver six months from now. Twelve of thirteen patients who wanted to become pregnant have conceived. The ability to become pregnant and deliver normal children after intensive treatment with combined radiation and chemotherapy (RT/TVPP) was comparable to the patients' pretreatment record

    Nanotechnology and combination therapy are two major fields that show great promise in the treatment of cancer. The delivery of drugs via nanoparticles helps to improve drug’s therapeutic effectiveness while reducing adverse side effects associated with high dosage by improving their pharmacokinetics. Taking advantage of molecular markers over-expressing on tumor tissues compared to normal cells, an “active” molecular marker targeted approach would be beneficial for cancer therapy. These actively targeted nanoparticles would increase drug concentration at the tumor site, improving efficacy while further reducing chemo-resistance. The multidisciplinary approach may help to improve the overall efficacy in cancer therapy. This review article summarizes recent developments of targeted multifunctional nanoparticles in the delivery of various drugs for a combinational chemotherapy approach to cancer treatment and imaging.

    Full Text Available Background: The adjuvant short course 9-week trastuzumab combination therapy for human epidermal receptor 2 positive breast cancer patients may often be considered as a cost-effective and safe option and has important implications for the Indian subcontinent as well as other developing countries. However, such regimens of shorter duration trastuzumab therapy like FinHer, offered in view of economic constraints, may not be able to achieve globally comparable cure rates in early breast cancer especially with high-risk women with more than 3 lymph node positive. Methods and Material: Outcome of 21 patients with HER2 positive breast cancer was treated with short course trastuzumab combination chemotherapy in the adjuvant setting was studied. Results: Out of 21 patients 15 are alive and disease free with a follow up of up to 73 months (median follow up 42 months.

    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.)

    The effectiveness of topical drugs for treatment of non-melanoma skin cancer is greatly reduced by insufficient penetration to deep skin layers. Ablative fractional lasers (AFLs) are known to enhance topical drug uptake by generating narrow microchannels through the skin, but information on AFL-drug delivery in in vivo conditions is limited. In this study, we examined pharmacokinetics, biodistribution and toxicity of two synergistic chemotherapy agents, cisplatin and 5-fluorouracil (5-FU), following AFL-assisted delivery alone or in combination in in vivo porcine skin. Detected at 0-120 h using mass spectrometry techniques, we demonstrated that fractional CO 2 laser pretreatment (196 microchannels/cm 2 , 852 μm ablation depth) leads to rapid drug uptake in 1500 μm deep skin layers, with a sixfold enhancement in peak cisplatin concentrations versus non-laser-treated controls (5 h, P = 0.005). Similarly, maximum 5-FU deposition was measured within an hour of AFL-delivery, and exceeded peak deposition in non-laser-exposed skin that had undergone topical drug exposure for 5 days. Overall, this accelerated and deeper cutaneous drug uptake resulted in significantly increased inflammatory and histopathological effects. Based on clinical scores and transepidermal water loss measurement, AFL intensified local toxic responses to drugs delivered alone and in combination, while systemic drug exposure remained undetectable. Quantitative histopathologic analyses correspondingly revealed significantly reduced epidermal proliferation and greater cellular apoptosis after AFL-drug delivery; particularly after combined cisplatin + 5-FU exposure. In sum, by overcoming the primary limitation of topical drug penetration and providing accelerated, enhanced and deeper delivery, AFL-assisted combination chemotherapy may represent a promising treatment strategy for non-melanoma skin cancer.

    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 (RBE 10 ) 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

    Purpose : To evaluate the role of combination therapy of external radiotherapy and chemotherapy in the management of advanced esophageal cancer as a primary treatment compared with radiation therapy alone. Methods and Materials : A retrospective review of evaluable 55 esophageal cancer patients referred to the Department of Therapeutic Radiology, Paik Hospital for the external radiotherapy between Jul. 1983 and Dec.1994 was undertaken. Combined therapy patients (A group) were 30 and radiation alone patients (B group) were 25. Median age was 60 years old in A group(ranges : 42-81) and 65 years old in B group (ranges : 50-81). The male patients were 53. The fifty patients had squamous cell carcinomas. Radiation doses of 2520-6480c Gy were delivered over a period of 4-7 weeks. using 4MV LIVAC. Chemotherapy was administered in bolus injection before, after, or during the course of external radiotherapy. The local control rate and patterns of failure according to both treatment modalities and 1,2 year survival rates according to prognostic factors (stage, tumor length, radiation dose etc.) were analysed. Results : Median follow up period was 7 months (range : 2-73 months). Median survival was 7.5 months (20 days-29 months) in A group and 5 months(20 days-73 months) in B group. The 1,2 YSRs were 26.7%, 8.9% in A group. 12.7%, 4.3% in B group (p>0.05), respectively. The 1,2 YSRs according to stage(II/III), tumor length (5cm more or less). radiation dose(5000c Gy more or less) of A and B group were analyzed and the differences of survival rates of both treatments were not statistically significant. But among group B, patients who received 5000c Gy or more showed significant survival benefits (p<0.05). The treatment response rates of A and B group were 43.8%, 25.0%, respectively. Complete response rate of 25.0% in A and 8.3% in B were achieved. The local failure and distant metastasis were 52.4%, 23.8% in A group. 64.3%, 14.3% in B group, respectively. The combination

    Chemotherapy and primary site radiation therapy were compared to chemotherapy alone in a randomized study of 125 patients with small cell cancer of the lung. The sites of initial relapse, as well as disease free and overall survival were analyzed. Radiotherapy to the primary site reduced the rate of local relapse, but median survival was not prolonged in patients with either limited or extensive disease, when the radiation therapy-chemotherapy group was compared to the group that received chemotherapy alone

    Patients with pancreatic ductal adenocarcinomas (PDAC) have one of the poorest survival rates of all cancers. The main reason for this is related to the unique tumor stroma and poor vascularization of PDAC. As a consequence, chemotherapeutic drugs, such as nab-paclitaxel and gemcitabine, cannot efficiently penetrate into the tumor tissue. Non-invasive radiofrequency (RF) mild hyperthermia treatment was proposed as a synergistic therapy to enhance drug uptake into the tumor by increasing tumor vascular inflow and perfusion, thus, increasing the effect of chemotherapy. RF-induced hyperthermia is a safer and non-invasive technique of tumor heating compared to conventional contact heating procedures. In this study, we investigated the short- and long-term effects (~20 days and 65 days, respectively) of combination chemotherapy and RF hyperthermia in an orthotopic PDAC model in mice. The benefit of nab-paclitaxel and gemcitabine treatment was confirmed in mice; however, the effect of treatment was statistically insignificant in comparison to saline treated mice during long-term observation. The benefit of RF was minimal in the short-term and completely insignificant during long-term observation. Copyright © 2018 The Authors. Published by Elsevier Inc. All rights reserved.

    Cartilage hair hypoplasia (CHH) is a rare autosomal recessive ribosomopathy characterised by skeletal and integumentary system manifestations. It may also present with varied forms and intensities of haematopoietic and/or immune disorders. We report a 27-year-old female who presented a picture of combined immunodeficiency after receiving an adriamycin-based chemotherapy regimen followed by autologous stem cell transplantation. Her medical history indicated neonatal dwarfism, recurrent ear, nose and throat and respiratory infections, and hypogammaglobulinaemia, which were suggestive of a primary minor B-cell immune deficiency. Taken together, the diagnosis of cartilage hair hypoplasia was suspected and confirmed by means of molecular biological analysis. Here, we discuss the causal relationship and molecular mechanisms existing between both primary immunodeficiency and lymphoma conditions and between chemotherapy cytotoxicity and aggravation of the immune system and associated hematopoietic dysfunction, considering the role of all these components in light of the initially undiagnosed cartilage hair hypoplasia. Finally, this case highlights the importance of screening for primary immunodeficiencies in the setting of a diagnosis of lymphoma and/or dwarfism; moreover, CHH must be distinguished from other causes of small size; its diagnosis and complete check-up must include the molecular characterisation, and its management must be global in collaboration with haematologists, immunologists and internists.

    Prognosis of patients with head and neck squamous cell carcinoma (HNSCC) is still poor. Novel therapeutic approaches are of great interest to improve the effects of radiochemotherapy. We evaluated the effects of tyrosine kinase inhibitor neratinib on HNSCC cell lines CAL27, SCC25 and FaDu as a single agent and in combination with irradiation and chemotherapy. Effects of neratinib were evaluated in HNSCC cell lines CAL27, SCC25 and FaDu. Effect on cell viability of neratinib and combination with cisplatin and irradiation was measured using CCK-8 assays and clonogenic assays. Western blot analysis was performed to distinguish the effect on epithelial growth factor receptor and HER2 expression. Apoptosis was evaluated by flow cytometry analysis. Growth inhibition was achieved in all cell lines, whereas combination of cisplatin and neratinib showed greater inhibition than each agent alone. Apoptosis was induced in all cell lines. Combination of neratinib with irradiation or cisplatin showed significantly increased apoptosis. In clonogenic assays, significant growth inhibition was observed in all investigated cell lines. Neratinib, as a single agent or in combination with chemo-irradiation, may be a promising treatment option for patients with head and neck cancer. © 2016 John Wiley & Sons A/S.

    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

    Total cystectomy and urinary diversion are the standard treatments for invasive bladder cancer. However, total cystectomy is not possible in some patients due to advanced age, a poor general condition, or refusal to undergo cystectomy. In such cases, intra-arterial chemotherapy (IAC) and/or radiotherapy are the alternative treatments. We performed IAC with cisplatin and adriamycin in 9 patients with invasive bladder cancer and obtained complete response (CR) in 5 out of the 9 patients (55.6%). However, 3 of these 5 CR patients developed local recurrence within 1 year. In an effort to improve the efficacy, we performed combination therapy comprising IAC plus radiotherapy in 12 patients with invasive bladder cancer. CR was obtained in 58.3% and the bladder was preserved in 91.7% with this combination therapy. However, distant metastases developed in 33.3% after the combined treatment of IAC plus radiation therapy. These findings suggest that the combination of radiotherapy and IAC is useful for local control of invasive bladder cancer. Data from more cases and results from a longer follow-up are needed to fully confirm the efficacy of this type of treatment. In addition, therapeutic modalities to prevent distant metastasis need to be considered. (author)

    In 43 cases of small cell carcinoma of the lung, a combined treatment has been initiated with three drugs (cyclophosphamide 750 mg/m 2 , adriamycin 50 mg/m 2 and vincristine sulphate 1 or 2 mg total dosis), split-course-radiation therapy on the primary tumour (3500 rads) and prophylactic irradiation of the brain (2000 rads). The median survival of the 34 cases evaluable at day 50 attains 253 days. A more favourable evolution is observed for patients with a good response after therapy (median survival: 315 days) and for cases with limited disease (321 days) than for non-responders (median survival: 157 days) and for cases with extensive disease (median survival: 214 days). In spite of tumour site irradiation, prophylactic irradiation of CNS and chemotherapy, there were six local relapses, two CNS extensions and six metastatic relapses and only two autopsied cases without macroscopic evidence of relapse.

    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.

    increased subG1 in cell cycle was seen in the epirubicin and sunitinib combination treatment group. The activation of apoptosis pathway was confirmed by increased cleaved caspase-3 and cleaved PARP in MBT-2 cells. In tail vein tumor inoculation C3H mice model, epirubicin alone and sunitinib combination therapy decreased tumor growth in lungs with marginal effect. Sunitinib and epirubicin combination had shown a synergistic cytotoxic effect and inhibited cell migration ability in MBT-2 cells. The combination can induce cell cycle arrest at G2/M phase and increase subG1 cells. Metastatic animal study also showed that sunitinib combined with epirubicin has a marginal effect on inhibition of tumor growth of lungs. The tyrosine kinase receptor inhibitor-targeted combined chemotherapy regimen may provide as a new treatment modality for advanced bladder cancer in the future.

    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.

    As an angiogenesis inhibitor, bevacizumab has been investigated in combination with different chemotherapeutic agents, achieving an established role for metastatic cancer treatment. However, potential synergic anti-angiogenic effects of hyperthermia have not tested to date in literature. The aim of our study was to analyze efficacy, safety, and survival of anti-angiogenic-based chemotherapy associated to regional deep capacitive hyperthermia (HT) in metastatic cancer patients. Twenty-three patients with metastatic colorectal ( n = 16), ovarian ( n = 5), and breast ( n = 2) cancer were treated with HT in addition to a standard bevacizumab-based chemotherapy regimen. Treatment response assessment was performed, according to the modified Response Evaluation Criteria for Solid Tumors (mRECIST), at 80 days (timepoint-1) and at 160 days (timepoint-2) after therapy. Disease Response Rate (DRR), considered as the proportion of patients who had the best response rating (complete response (CR), partial response (PR), or stable disease (SD)), was assessed at timepoint-1 and timepoint-2. Chi-squared for linear trend test was performed to evaluated the association between response groups (R/NR) and the number of previous treatment (none, 1, 2, 3), number of chemotherapy cycles (12), number of hyperthermia sessions (24), and lines of chemotherapy (I, II). Survival curves were estimated by Kaplan-Meier method. DRR was 85.7% and 72.2% at timepoint-1 and timepoint-2, respectively. HT was well tolerated without additional adverse effects on chemotherapy-related toxicity. Chi-squared for linear trend test demonstrated that the percentage of responders grew in relation to the number of chemotherapy cycles ( p = 0.015) and to number of HT sessions ( p chemotherapy cycles ( p chemotherapy with HT has a favorable tumor response, is feasible and well tolerated, and offers a potentially promising option for metastatic cancer patients.

    Despite the existence of the prophylactic Bacille Calmette-Guérin (BCG) vaccine, infection by Mycobacterium tuberculosis (Mtb) remains a major public health issue causing up to 1.8 million annual deaths worldwide. Increasing prevalence of Mtb strains resistant to antibiotics represents an urgent threat for global health that has prompted a search for alternative treatment regimens not subject to development of resistance. Immunotherapy constitutes a promising approach to improving current antibiotic treatments through engagement of the host's immune system. We designed a multi-antigenic and multiphasic vaccine, based on the Modified Vaccinia Ankara (MVA) virus, denoted MVATG18598, which expresses ten antigens classically described as representative of each of different phases of Mtb infection. In vitro analysis coupled with multiple-passage evaluation demonstrated that this vaccine is genetically stable, i.e. fit for manufacturing. Using different mouse strains, we show that MVATG18598 vaccination results in both Th1-associated T-cell responses and cytolytic activity, targeting all 10 vaccine-expressed Mtb antigens. In chronic post-exposure mouse models, MVATG18598 vaccination in combination with an antibiotic regimen decreases the bacterial burden in the lungs of infected mice, compared with chemotherapy alone, and is associated with long-lasting antigen-specific Th1-type T cell and antibody responses. In one model, co-treatment with MVATG18598 prevented relapse of the disease after treatment completion, an important clinical goal. Overall, results demonstrate the capacity of the therapeutic MVATG18598 vaccine to improve efficacy of chemotherapy against TB. These data support further development of this novel immunotherapeutic in the treatment of Mtb infections.

    Objective: To research the early effects and side-effects of the local advanced nasopharyngeal carcinoma patients using intensity-modulated radiotherapy (IMRT) combined with concurrent chemotherapy. Methods: From January 2005 to January 2007, 60 patients with nasopharyngeal carcinoma of stage m-IV b were received IMRT combined with concurrent chemotherapy in our center. Sixty patients were divided into paclitaxel concurrent group (32 patients) and cisplatin concurrent group (28 patients). The prescribing doses of the primary tumor were 68-72 Gy for each group. The patients of paclitaxel concurrent group received 5-7 times pacitaxel liposome chemotherapy of 30 mg · m -2 ·. The patients of cisplatin concurrent group received 5-7 times cisplatin chemotherapy of 30 mg · m -2 · week -1 . Results: As to the side-effects, the patients of the cisplatin concurrent group got earlier radiodermatitis and radiation-induced mucositis but also got significantly higher rate of radiodermatitis, radiation-induced mucositis, radiation-induced leucopenia and gastrointestinal toxicity, as well as the loss of weight. No significant difference was found on liver and renal functions between two groups.Four patients (12.5%) of the paclitaxel concurrent group were broken-off, which was much better than the cisplatin concurrent group. There was no significant difference on the specific length of break-off time, the 2-year overall survival rate and the 2-year diseaee-free survival rate between two groups. Conclusions: IMRT combined with concurrent chemotherapy of paclitaxel liposome for local advanced nasopharyngeal carcinoma results in less side-effects and better tolerance than IMRT combined with concurrent cisplatin chemotherapy.

    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

    Combined treatment is more effective than single treatment against most forms of cancer. In this work, doxorubicin loaded chitosan-W 18 O 49 nanoparticles combined with the photothermal therapy and chemotherapy are fabricated through the electrostatic interaction between positively charged chitosan and negatively charged W 18 O 49 nanoparticles. The in vitro and in vivo behaviors of these nanoparticles are examined by dynamic light scattering, transmission electron microscopy, cytotoxicity, near-infrared fluorescence imaging, and tumor growth inhibition experiment. These nanoparticles have a mean size around 110 nm and show a pH sensitive drug release behavior. After irradiation by the 980 nm laser, these nanoparticles show more pronounced cytotoxicity against HeLa cells than that of free doxorubicin or photothermal therapy alone. The in vivo experiments confirm that their antitumor ability is significantly improved, resulting in superior efficiency in impeding tumor growth and extension of the lifetime of mice. © 2017 WILEY-VCH Verlag GmbH & Co.

    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)

    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 cyclophosphamide 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 re immunizations 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.

    A retrospective study of 44 patients with rectal cancer who received preoperative radiation (42.6 Gy) combined with chemotherapy and 37 who received resection alone (control group) was undertaken to evaluate the effect of preoperative radiation therapy on local recurrence of rectal cancer. The rate of local recurrence in the radiation group was reduced to 4.5% compared with that in the controls (18.9%). From a pathological point of view, factors that have a close association with recurrence, such as depth of invasion, ew (defined as the distance between the external surgical surface and the deepest site of invasion) and lymph nodal involvement, have been successfully changed after radiation therapy. It was also evident that the rate of recurrence in irradiated patients, depth of invasion of a 2 (defined as the invasion of cancer far beyond the muscle layer but without involvement of other organs) or ew less than 2 mm was significantly lower than in patients with the same pathological conditions in whom radiation was not used. However, especially in patients with remote lymph node metastasis, there was no difference in local recurrence rate between the two groups. From these findings, it was concluded that a careful follow up is necessary for patients with remote lymph node involvement even after radiation therapy. (author)

    Full Text Available Cytoreductive surgery (CRS with heated intraoperative intraperitoneal chemotherapy (HIPEC has emerged as optimal treatment for diffuse malignant peritoneal mesothelioma (DMPM showing median survivals of 36–92 months. However, recurrences occur frequently even in patients undergoing optimal cytreduction and are often confined to the abdomen. We initiated a Phase II study of adjuvant intraperitoneal pemetrexed combined with intravenous cisplatin for patients undergoing CRS and HIPEC for DMPM. The treatment consisted of pemetrexed 500 mg/m2 intraperitoneally and cisplatin 50 mg/m2 intravenously given simultaneously on day 1 of every 21 day cycle for 6 cycles. The primary endpoint of the study was treatment related toxicity. From July 2007 until July 2009 ten patients were enrolled. Nine of 10 completed all 6 cycles of adjuvant treatment per protocol. The most common toxicities were fatigue, nausea and abdominal pain grade 1 or 2. There was one grade 3 toxicity consisting of a catheter infection. The median survival for all 10 patients was 33.5 months. Pharmacokinetic analysis of intraperitoneal pemetrexed showed a peritoneal to plasma area under the curve ratio of 70. Our study shows that adjuvant intravenous cisplatin and intraperitoneal pemetrexed can be used following CRS and HIPEC for DMPM with low morbidity.

    Changes of several immunological parameters in 52 cases of primary lung cancer treated with radiation combined chemotherapy were studied in the present paper. During the treatment, decreasing of absolute lymphocyte counts, PHA skin test reactivity and lymphocyte blastoid transformation with PHA were recognized. The decreasing of immunological capacities tested in the present investigation did not depend on among clinical stages or histologic types. But irradiation to mediastinum affected to immunological abilities. The values in some immunological parameter tested at pre-treatment or at post-treatment suggested the correlation with tumor regression, namely in the cases showed high values in absolute lymphocyte counts and PPD skin test reactivity at the time of pre-treatment and in the cases showed high reactivity in PHA skin test at post-treatment, tumor regression was significantly demonstrated compared with the other cases. The patients showed high values in absolute lymphocyte counts and PHA skin test at pretreatment time or showed high values in lymphocyte blastoid transformation with PHA at post-treatment demonstrated longer survival time. As a result, the test of immunological abilities obtained at pre-treatment time was reliable to forecast tumor regression and survival time. (author)

    Full Text Available Current global helminth control guidelines focus on regular deworming of targeted populations for morbidity control. However, water, sanitation, and hygiene (WASH interventions may also be important for reducing helminth transmission. We evaluated the impact of different potential helminth protective packages on infection prevalence, including repeated treatment with albendazole and praziquantel with and without WASH access.We conducted a cohort study nested within a randomized trial of empiric deworming of HIV-infected adults in Kenya. Helminth infections and infection intensity were diagnosed using semi-quantitative real-time PCR. We conducted a manual forward stepwise model building approach to identify if there are packages of interventions that may be protective against an STH infection of any species (combined outcome and each helminth species individually. We conducted secondary analyses using the same approach only amongst individuals with no anthelmintis exposure. We used interaction terms to test for potential intervention synergy. Approximately 22% of the 701 stool samples provided were helminth-infected, most of which were of low to moderate intensity. The odds of infection with any STH species were lower for individuals who were treated with albendazole (aOR:0.11, 95%CI: 0.05, 0.20, p<0.001, adjusting for age and sex. Although most WASH conditions demonstrated minimal additional benefit in reducing the probability of infection with any STH species, access to safe flooring did appear to offer some additional protection (aOR:0.34, 95%CI: 0.20, 0.56, p<0.001. For schistosomiasis, only treatment with praziquantel was protective (aOR:0.30 95%CI: 0.14, 0.60, p = 0.001. Amongst individuals who were not treated with albendazole or praziquantel, the most protective intervention package to reduce probability of STH infections included safe flooring (aOR:0.34, 95%CI: 0.20, 0.59, p<0.001 and latrine access (aOR:0.59, 95%CI: 0.35, 0.99, p = 0

    Neoadjuvant chemoradiotherapy (CTRT) is the current standard of care for treatment of locally advanced cancer of the esophagus or gastroesophageal junction. Many efforts have been made over the last years to identify the best chemotherapy and radiotherapy combination regimen, but specific randomized trials addressing this issue are still lacking. Areas covered: A systematic review of the literature was performed searching in PubMed all published studies of combinations CTRT regimens for operable or unresectable esophageal cancer to describe activity and toxicity. Studies considered were prospective series or clinical phase II-III trials including at least 40 patients and published in English language. Expert commentary: Long-term results of CROSS trial have established RT combined with carboplatin plus paclitaxel chemotherapy as the preferred neoadjuvant treatment option for both squamous and adenocarcinoma of the esophagus. More effective multimodal treatment strategies integrating novel biological agents including immunotherapy and based on an extensive molecular tumor characterization are eagerly awaited.

    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)

    2018-01-01

    Full Text Available This case report documents the clinical and pathologic findings in a 12-year-old terrier mix with intraocular and splenic hemangiosarcoma. Pathologic findings in both the spleen and globe were consistent with hemangiosarcoma with a low mitotic count. Initial treatment consisted of enucleation and then splenectomy followed by one cycle of conventional doxorubicin chemotherapy. Due to poor tolerance, a subsequent treatment regimen consisted of metronomic chemotherapy with chlorambucil combined with an alternative/complementary regimen of I’m-Yunity (polysaccharopeptide and Yunnan Baiyao. Follow-up thoracic radiographs and abdominal ultrasounds over a period of 24 months showed no evidence of pulmonary, hepatic, or right atrial metastases, during which time the patient had an excellent quality of life. However, shortly after achieving two-year survival, the patient developed new onset seizures unresponsive to anticonvulsant therapy. Therefore, a decision was made to euthanize the dog given that the most likely etiology of the seizures was a brain tumor. Overall, this is an exceptional treatment response given the poor survival statistics of hemangiosarcoma even with conventional chemotherapy. However, additional clinical pharmacology and clinical trial data are needed to further support the use of a complementary/holistic approach in combination with metronomic chemotherapy.

    Objective: To evaluate the effect and complication of induction chemotherapy combined with three-dimensional conformal radiation therapy (3DCRT) for locally advanced non small cell lung cancer (NSCLC). Methods: Ninety-two such patients were randomized into radiation therapy alone group(RT-, 50 patients) and induction chemotherapy combined radiotherapy group (CMT-, 42 patients). The induction chemotherapy consisted of 2-4 cycles of platinum-based regimen. Results: The overall median survival time was 15 months with 12 months in the RT group and 18 months in the CMT group (P=0.014) respectively. The 1-year overall survival rates were 48.6% and 71.2% in RT and CMT group, respectively (P=0.004). The 2-year survival rates were 20.8% and 37.6% in RT and CMT group, respectively (P=0.041). Treatment was well tolerated and the toxicities were similar in either group. Conclusion: The addition of induction chemotherapy to 3DCRT takes a survival advantage over 3DCRT alone for Stage III NSCLC without increasing toxicities. (authors)

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

    In the USA the recommended treatment for patients with muscle-invading transitional cell cancer of the bladder is usually radical cystectomy. Conservative surgery (transurethral resection and partial cystectomy), irradiation, and cis-platinum 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. Initial response and local control rates are improved when a multimodality approach is used. Up to 85% of patients selected for bladder sparing therapy on the basis of their initial response to chemo-radiation may keep their bladders. This figure could increase further when other powerful prognostic factors, such as the presence of hydronephrosis or carcinoma in situ, are taken into account in initial patient selection. Deferring the patient from immediate cystectomy does not appear to compromise survival. The most appropriate sequencing of radiation and chemotherapy is yet to be established. Concomitant cis-platinum and irradiation improves local control and bladder preservation when compared with irradiation alone but does not decrease the metastatic rate. It is hoped that the well recognized activity of cis-platinum based combination chemotherapy in advanced disease will translate into effective eradication of micrometastatic disease (known to be present in up to 40% of patients at diagnosis). This has yet to be clearly demonstrated in a randomized trial. The addition of combination chemotherapy to radiation does not increase bladder morbidity but carries a considerable systemic risk. Thus, despite promising phase II studies, until a survival benefit is proven in a randomized trial, neoadjuvant or adjuvant combination chemotherapy in conjunction with irradiation should continue to be regarded as experimental

    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.

    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)

    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.

    Objective: To evaluate the efficacy and toxicity of gemcitabine plus cisplatin (GP) chemotherapy combined with intensity-modulated radiation therapy (IMRT) in locoregionally advanced nasopharyngeal carcinoma (NPC). Methods: 71 patients (Stage III: 41, Stage IV A : 30) with locoregionally advanced NPC were entered this study. Neoadjuvant chemotherapy was consisted of cisplatin 25 mg/m 2 intravenously on d1-3 and gemcitabine 1000 mg/m 2 in 30 minutes intravenous infusion on days 1 and 8, every 3 weeks for 2 cycles. Adjuvant chemotherapy consisted of 2 cycles of the same GP regimen was given at 28 days after the end of radiotherapy. The prescription doses was 66.0-70.4 Gy to the gross tumor volume, 66 Gy to positive neck nodes, 60 Gy to the high-risk clinical target volume, 54 Gy to the low-risk clinical target volume. Results: The overall response rate to neoadjuvant chemotherapy was 91.2%, acute toxicity was mainly grade 1-2 myleosuppression. All patients completed IMRT. The median follow-up duration was 38 months. The 3-year nasopharyngeal local control, regional control, distant metastasis-free survival rate and overall survival rate were 93%, 99%, 91%, 90%, respectively. Severe late toxicities included grade 3 trismus in 1 patient, grade 3 hearing impairment in 2 patients and cranial nerve palsy in 2 patients, respectively. No grade 4 late toxicities were observed. Conclusions: The combination of GP chemotherapy and IMRT for locoregionally advanced nasopharyngeal carcinoma is well-tolerated, convenient, effective, and warrants further studies of more proper cycles of GP regimen.

    To investigate the effectiveness of hyperthermia in the preoperative combined treatment of radiation, chemotherapy and hyperthermia for rectal carcinoma, two groups were compared. Group A consisted of 18 patients in whom hyperthermia, radiation and chemotherapy were performed. Group B consisted of 18 patients in whom only chemotherapy and radiation were performed. The total dose of radiation in both of the two groups was 40.5 Gy, and a radiation field covering the whole pelvis was used. Hyperthermia was performed using 8 MHz radiofrequency waves (Thermotron RF8, Yamamoto Vinyter, Japan), and tumors were heated at about 42 degrees C for 50 minutes. Hyperthermia was repeated five times during the preoperative treatment. Chemotherapy was performed by giving 5-fluorouracil suppositories to a total dose of 3400 mg. Mean tumor reduction rates on barium enema were 31.8% in group A and 18.2% in group B. The difference was statistically significant. The result of the histological assessment of tumor necrosis showed that there was a significantly higher degree of necrosis in group A than in group B. These results showed that the addition of hyperthermia enhanced tumor necrosis. It was concluded that the addition of hyperthermia would be an effective preoperative treatment of rectal carcinoma.

    1986-01-01

    This report concerns the design and results of a randomized prospective trial (SECOG I) in the treatment of advanced Stage III and IV head and neck cancer with radical radiotherapy combined with polychemotherapy. Synchronous administration of chemotherapy and radiotherapy was compared with sequential chemotherapy and radiotherapy and VBM (vincristine, bleomycin and methotrexate) compared with VBM plus 5-fluorouracil in a 2 x 2 standard factorial design. Two-hundred-and-seventy patients were entered and 267 were included in the analysis. Treatment did not present serious problems of toxicity. The addition of 5-fluorouracil to VBM produced a significant improvement in disease-free survival (P=0.04) though not in overall survival. Synchronous chemotherapy was similarly better than sequential chemotherapy, though not significantly so (P=0.1). A new study (SECOG II), based on this was started in February 1984, and one-third of the patients are now being allocated to treatment by radiotherapy as the sole method of treatment. (author)

    Purpose: To report outcomes for patients with resected pancreas cancer treated with an adjuvant regimen consisting of gemcitabine-based combination chemotherapy followed by capecitabine and radiation. Patients and Methods: We performed a retrospective review of a series of patients treated at a single institution with a common postoperative adjuvant program. Between January 2002 and August 2006, 43 resected pancreas cancer patients were offered treatment consisting of 4, 21-day cycles of gemcitabine 1 g/m 2 intravenously over 30 min on Days 1 and 8, with either cisplatin 35 mg/m 2 intravenously on Days 1 and 8 or capecitabine 1500 mg/m 2 orally in divided doses on Days 1-14. After completion of combination chemotherapy, patients received a course of radiotherapy (54 Gy) with concurrent capecitabine (1330 mg/m 2 orally in divided doses) day 1 to treatment completion. Results: Forty-one patients were treated. Median progression-free survival for the entire group was 21.7 months (95% confidence interval 13.9-34.5 months), and median overall survival was 45.9 months. In multivariate analysis a postoperative CA 19-9 level of ≥180 U/mL predicted relapse and death. Toxicity was mild, with only two hospitalizations during adjuvant therapy. Conclusions: A postoperative adjuvant program using combination chemotherapy with gemcitabine and either cisplatin or capecitabine followed by radiotherapy with capecitabine is tolerable and efficacious and should be considered for Phase III testing in this group of patients.

    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

    Full Text Available ObjectiveTo investigate the clinical effect of systemic chemotherapy combined with transcatheter arterial chemoembolization (TACE in the treatment of breast cancer with liver metastases. MethodsA total of 86 female breast cancer patients with liver metastases who were treated in the Affiliated Hospital of Shandong Academy of Medical Sciences from December 2012 to December 2014 were selected and equally divided into experimental group and control group. The patients in the control group received systemic chemotherapy, and those in the experimental group received systemic chemotherapy combined with TACE. The clinical effect, changes in lesions, and patients′ quality of life (QOL scores after treatment were compared between two groups. The t-test was applied for comparison of continuous data between the two groups, and the chi-square test was applied for comparison of categorical data between the two groups. ResultsThe experimental group had a significantly higher overall response rate than the control group (90.70% vs 58.14%, χ2=13.07, P=0.001. Compared with the control group, the experimental group had significantly smaller diameters of tumors and lymph nodes after treatment (t=4.26 and 4.63, both P<0.001, as well as significantly higher QOL scores at 3 and 6 months after treatment (t=6.30 and 3.89, both P<0001. ConclusionSystemic chemotherapy combined with TACE has a significant therapeutic effect in breast cancer patients with liver metastases, and can improve patients′ symptoms, reduce adverse drug reactions, and improve QOL. As a safe and reliable therapeutic method, it is worthy of clinical application.

    To overcome the limitations of expandable metallic stent placement by using balloon dilation combined with chemotherapy or radiation therapy in the treatment of malignant esophageal strictures involving the esophagogastric junction (EGJ). Fluoroscopically guided balloon dilation was performed in 14 patients with strictures due to squamous cell carcinoma (n=5) or adenocarcinoma (n=9). After balloon dilation all patients underwent chemotherapy or radiation therapy. There were no failures or major complications After dilation, dysphagia improved in 13 (92%) of 14 patients, and the long-term success rate was 50%. Six of the seven patients in whom the condition recurred underwent further balloon dilation (n=4) or placement of an expandable metallic stent (n=2). Ten of the 13 who were followed up died after diffuse metastasis. Prior to their eventual death (mean survial, 20 weeks), the dysphagia experienced by seven (70%) of these ten improved, and thus they required no further treatment. Balloon dilation combined with chemotherapy or radiation therapy seems to be a safe and effective secondary therapy for patients with dysphagia due to malignant stricture involving the EGJ

    PURPOSE: We report results of a randomized prospective study that compared single agents of low toxicity given both as the first-line and second-line chemotherapy with combination chemotherapy in advanced breast cancer with distant metastases. PATIENTS AND METHODS: Patients in the single-agent arm...... (n = 153) received weekly epirubicin (E) 20 mg/m2 until progression or until the cumulative dose of 1,000 mg/m2, followed by mitomycin (M) 8 mg/m2 every 4 weeks, and those in the combination chemotherapy arm (n = 150) were first given cyclophosphamide 500 mg/m2, E 60 mg/m2, and fluorouracil 500 mg/m2...... younger than 50. RESULTS: An objective response (complete [CR] or partial [PR]) was obtained in 55%, 48%, 16%, and 7% of patients treated with CEF, E, M, and MV, respectively. A response to CEF tended to last longer than a response to E (median, 12 v 10.5 months; P = .07). Treatment-related toxicity...

    The treatment of the primary tumor in advanced metastatic colorectal cancer (CRC) is still a matter of discussion. Little attention has thus far been paid to the endoscopically observable changes of the primary in non-curatively resectable stage IV disease. 20 patients [14 men, 6 women, median age 67 (39–82) years] were observed after initial diagnosis of non-curatively resectable metastasized symptomatic (83%) or asymptomatic (17%) CRC, from June 2002 to April 2009. If necessary, endoscopic tumor debulking was performed. 5-FU based chemotherapy was given immediately thereafter. In 10 patients, chemotherapy was combined with antibody therapy. Response of the primary was observed in all patients. Local symptoms were treated endoscopically whenever necessary (obstruction or bleeding), and further improved after chemotherapy was started: Four patients showed initial complete endoscopic disappearance of the primary. In an additional 6 patients, only adenomatous tissue was histologically detected. In both these groups, two patients revealed local tumor relapse after interruption of therapy. Local tumor regression or stable disease was achieved in the remaining 10 patients. 15 patients died during the observation time. In 13 cases, death was related to metastatic disease progression. The mean overall survival time was 19.6 (3–71) months. No complications due to the primary were observed. This study shows that modern anti-cancer drugs combined with endoscopic therapy are an effective and safe treatment of the symptomatic primary and ameliorate local complaints without the need for surgical intervention in advanced UICC stage IV CRC

    Palliation of unresectable head and neck cancer remains a difficult problem. Because of excellent results reported by others with infusion of vinblastine, methotrexate, and 5-fluorouracil into the external carotid artery followed by irradiation before curative surgery, we applied this technic to 22 patients with advanced head and neck cancer. Fifteen patients from this group who had chemotherapy infusion followed by radiation therapy are compared with 21 patients who received radiation therapy alone. Both groups were similar in distribution of primary site, histology, and TNM stage. Of 15 patients, 14 (93%) had partial or complete tumor regression after both arterial chemotherapy infusion and irradiation, while 14 of 17 patients (82%) receiving primary irradiation had partial or complete response. Drug toxicity and complications related to infusion occurred in all patients. Most patients in both groups had short survivals (mean of 14.1 months in infusion chemotherapy and radiation vs 9.1 months in primary irradiation). One patient remains alive in the infusion group and two in the control group; however, all have recurrent disease. Results indicate a slight increase in survival time with the addition of infusion chemotherapy to irradiation in palliative treatment of head and neck cancer

    The treatment of human cancer has been seriously hampered for decades by resistance to chemotherapeutic drugs. A very efficient mechanism of tumor resistance to drugs is the proton pumps-mediated acidification of tumor microenvironment. Metronomic chemotherapy has shown efficacy in adjuvant fashion as well as in the treatment of pets with advanced disease. Moreover, we have shown in veterinary clinical settings that pre-treatment with proton-pumps inhibitors (PPI) increases tumor responsiveness to chemotherapeutics. In this study pet with spontaneously occurring cancer have been recruited to be treated by a combination of metronomic chemotherapy and high dose PPIs and their responses have been matched to those of a historical control of ten patients treated with metronomic chemotherapy alone. Single arm, non randomized phase II open study, with historical control group, evaluating safety and efficacy of the combination of metronomic chemotherapy and alkalization. Twenty-four companion animals (22 dogs and 2 cats) were treated adding to their metronomic chemotherapy protocol the pump inhibitor lansoprazole at high dose, and a water alkalizer. Their responses have been evaluated by clinical and instrumental evaluation and matched to those of the control group. The protocol was overall well tolerated, with only two dogs experiencing side effects due to gastric hypochlorhydria consisting with vomiting and or diarrhea. In terms of overall response, in the alkalized cohort, 18 out of 24 had partial or complete responses (75%), two patients had a stable disease and the remaining patients experienced no response or progressive disease. On the other hand, only one patient in the control group experienced a complete response (10%) and three other experienced short lived responses. Median time to terminal event was 34 weeks for the experimental group versus 2 weeks in the controls (p= 0.042). Patient alkalization has shown to be well tolerated and to increase tumor response

    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......-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 optimization, but more clinical data is required to facilitate evidence-based plan optimization in the multi-modality setting....... 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...

    Trastuzumab (Herceptin) is the first humanized monoclonal antibody targeting the HER2 antigen in breast cancer. HER2 receptor has been individualised 20 years ago. During the past 10 years, trastuzumab administration has radically modified the prognosis of the patients that are treated for HER2 positive breast cancer. Its efficacy has been demonstrated in the metastatic and adjuvant settings. While, trastuzumab based-regimens became the standard of care in the treatment of HER2/neu positive breast cancer, the optimal combination (concurrently or sequentially) to chemotherapy and radiation therapy is still unknown. Indeed, while the concurrent administration of trastuzumab and anthracyclines is not recommended because of a high risk of cardiac toxicity, there is no published data on the best sequence of trastuzumab and radiation therapy administration, particularly when internal mammary chain is involved. The benefit/risk ratio of the concurrent and sequential administration of trastuzumab with chemotherapy and radiation therapy will be discussed in this review. (authors)

    Seven cases of soft tissue sarcoma developing after primary or postoperative radiotherapy for breast carcinoma are reported. The sarcomas occurred within the irradiated volume, after a latent period of 4-26 years. These cases conform well to established criteria for the diagnosis of radiation-induced sarcoma. Chemotherapy, consisting of the four-drug combination CYVADIC (cyclophosphamide, vincristine, adriamycin, DTIC) was employed in six of the seven patients. Only two of them achieved partial remission, lasting only 2 and 3 months, respectively. The effectiveness of adriamycin-containing chemotherapy regimens in soft tissue sarcomas as well as the remote hazard of radiation-related sarcoma in primary or postoperative breast irradiation are discussed

    Short-term starvation prior to chemotherapy administration protects mice against toxicity. We undertook dose-escalation of fasting prior to platinum-based chemotherapy to determine safety and feasibility in cancer patients. 3 cohorts fasted before chemotherapy for 24, 48 and 72 h (divided as 48 pre-chemo and 24 post-chemo) and recorded all calories consumed. Feasibility was defined as ≥ 3/6 subjects in each cohort consuming ≤ 200 kcal per 24 h during the fast period without excess toxicity. Oxidative stress was evaluated in leukocytes using the COMET assay. Insulin, glucose, ketones, insulin-like growth factor-1 (IGF-1) and IGF binding proteins (IGFBPs) were measured as biomarkers of the fasting state. The median age of our 20 subjects was 61, and 85 % were women. Feasibility criteria were met. Fasting-related toxicities were limited to ≤ grade 2, most commonly fatigue, headache, and dizziness. The COMET assay indicated reduced DNA damage in leukocytes from subjects who fasted for ≥48 h (p = 0.08). There was a non-significant trend toward less grade 3 or 4 neutropenia in the 48 and 72 h cohorts compared to 24 h cohort (p = 0.17). IGF-1 levels decreased by 30, 33 and 8 % in the 24, 48 and 72 h fasting cohorts respectively after the first fasting period.

    Short-term starvation prior to chemotherapy administration protects mice against toxicity. We undertook dose-escalation of fasting prior to platinum-based chemotherapy to determine safety and feasibility in cancer patients. 3 cohorts fasted before chemotherapy for 24, 48 and 72 h (divided as 48 pre-chemo and 24 post-chemo) and recorded all calories consumed. Feasibility was defined as ≥ 3/6 subjects in each cohort consuming ≤ 200 kcal per 24 h during the fast period without excess toxicity. Oxidative stress was evaluated in leukocytes using the COMET assay. Insulin, glucose, ketones, insulin-like growth factor-1 (IGF-1) and IGF binding proteins (IGFBPs) were measured as biomarkers of the fasting state. The median age of our 20 subjects was 61, and 85 % were women. Feasibility criteria were met. Fasting-related toxicities were limited to ≤ grade 2, most commonly fatigue, headache, and dizziness. The COMET assay indicated reduced DNA damage in leukocytes from subjects who fasted for ≥48 h (p = 0.08). There was a non-significant trend toward less grade 3 or 4 neutropenia in the 48 and 72 h cohorts compared to 24 h cohort (p = 0.17). IGF-1 levels decreased by 30, 33 and 8 % in the 24, 48 and 72 h fasting cohorts respectively after the first fasting period. Fasting for 72 h around chemotherapy administration is safe and feasible for cancer patients. Biomarkers such as IGF-1 may facilitate assessment of differences in chemotherapy toxicity in subgroups achieving the physiologic fasting state. An onging randomized trial is studying the effect of 72 h of fasting. NCT00936364 , registered propectively on July 9, 2009.

    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.

    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

    To evaluate efficacies of three commonly used oral drugs including Berbamine Hydrochloride Tablet (B), Qijiao Shengbai Capsule (Q), and Leucogen Tablet (L) (by single drug, two drugs or three drugs) combined with granulocyte colony-stimulating factor (G-CSF) for treat ment of chemotherapy related leukocytopenia in mice. Totally 156 Kunming male mice were divided into the normal control group (A, n=24), the model group (B, n=24), the G-CSF group (C, n =24), the G-CSF+Q group (D, n=12), G-CSF+ B (E, n=12), the G-CSF+L group (F, n=12), the G-CSF + Q + B group (G, n=12), the G-CSF + Q + L group (H, n=12), the G-CSF + L + B group (I, n=12), and the G-CSF + L + Q + B (J, n=12). Mouse models of chemotherapy related leukocytopenia were established by intraperitoneal injection of cyclophosphamide (CTX). A G-CSF group was set up as a positive control. Mice were treated by a single oral drug, a single oral drug combined with G-CSF, and two or three drugs combined with G-CSF respectively, and the death rate calculated. Hemocytes [such as white blood cells (WBC) and its classification, red blood cells (RBC), platelet (PLT), hemoglobin (Hb)] were calculated by hematology analyzer. Mice were anatomized and important organs weighed. Organ indices were calculated. There was no statistical difference in the mortality rate among all groups (P > 0.05). Compared with Group B, WBC was elevated in all other groups (P drug B and L (P chemotherapy related leukopenia or decreased three blood series was to administrate three commonly oral drugs combined with G-CSF. Authors speculated that G-CSF and Q might have a certain effect on CTX induced immune inhibition.

    The Southwest Oncology Group did a limited institutional pilot study of the combination of doxorubicin and ifosfamide in the treatment of previously treated adult patients with acute leukemia. Thirty-four patients received one or two courses of the combination. All patients had received prior chemotherapy and 32 had received prior anthracycline chemotherapy. Three patients died before their responses could be fully evaluated. Fourteen patients achieved complete remission (41%) and one patient achieved partial remission. The complete remission rate was 27% for patients with acute myeloblastic leukemia (myelomonoblastic leukemia, monoblastic leukemia, and erythroleukemia) and 89% for patients with acute lymphocytic and undifferentiated leukemia (ALL). Toxic effects included severe hematologic reactions in 33 of 34 patients, hematuria in six patients, altered sensorium in one patient, and congestive heart failure in one patient. The safety of the combination was established and toxic side effects of this therapy were tolerable. The 89% complete remission rate for previously treated patients with ALL suggests that the combination of doxorubicin and ifosfamide may be particularly effective in ALL.

    A 38-year-old man was given a diagnosis of as sigmoid colon cancer and underwent sigmoid colectomy. Post-operative pathological staging was stage IIIb. He then underwent adjuvant chemotherapy. One year and 4 months after the surgery, CT scans revealed multiple liver and lung metastases. He was given mFOLFOX6+bevacizumab, which was changed later to FOLFIRI+bevacizumab. After these chemotherapies, he was admitted to the hospital due to sudden abdominal pain and high grade fever. Obstructive jaundice was initially diagnosed, but detailed study of initial CT revealed intragastric wall abscess. After the drainage of the abscess, his conditions improved. We speculated that the abscess formation was caused by mucosal damage due to bevacizumab.

    Full Text Available We present the case of a 51-year-old male patient who received adjuvant chemotherapy consisting of oxaliplatin, bolus and continuous 5-fluorouracil (5-FU and leucovorin after anterior resection because of locally advanced rectal cancer. Preoperative chemotherapy with capecitabine (an oral 5-FU prodrug had been well tolerated. Two days after initiation of the first course of chemotherapy, the patient reported typical chest pain. The ECG showed ST elevations and prominent T waves in almost all leads. Due to suspicion of a high-risk acute coronary syndrome, an urgent cardiac catheterization was performed. It showed a generally reduced coronary flow with multiple significant stenoses (including the ostia of the left and right coronary artery, as well as a highly reduced left ventricular function with diffuse hypokinesia. Due to the meanwhile completely stable situation of the patient after medical acute coronary syndrome treatment, no ad hoc intervention was performed to allow further discussion of the optimal management. Thereafter, the patient remained clinically asymptomatic, without any rise in cardiac necrosis parameters; only NT-pro-BNP was significantly elevated. A control cardiac catheterization 2 days later revealed a restored normal coronary artery flow with only coronary calcifications without significant stenoses, as well as a normal left ventricular ejection fraction. Cardiovascular symptoms occurred on the second day of continuous 5-FU treatment. As cardiotoxic effects seem to appear more frequently under continuous application of 5-FU, compared to the earlier established 5-FU bolus regimens, treating medical oncologists should pay special attention to occurring cardiac symptoms and immediately interrupt 5-FU chemotherapy and start a cardiologic work-up.

    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)

    To establish a set of guidelines for developing ambulatory chemotherapy preprinted orders. Multiple methods were used to develop the preprinted order guidelines. These included (A) a comprehensive literature review and an environmental scan; (B) analyses of field study observations and incident reports; (C) critical review of evidence from the literature and the field study observation analyses; (D) review of the draft guidelines by a clinical advisory group; and (E) collaboration with graphic designers to develop sample preprinted orders, refine the design guidelines, and format the resulting content. The Guidelines for Developing Ambulatory Chemotherapy Preprinted Orders, which consist of guidance on the design process, content, and graphic design elements of ambulatory chemotherapy preprinted orders, have been established. Health care is a safety critical, dynamic, and complex sociotechnical system. Identifying safety risks in such a system and effectively addressing them often require the expertise of multiple disciplines. This study illustrates how human factors professionals, clinicians, and designers can leverage each other's expertise to uncover commonly overlooked patient safety hazards and to provide health care professionals with innovative, practical, and user-centered tools to minimize those hazards.

    Between January, 1988 and January, 1991, 29 patients were treated with cyclophosphamide, adriamycin and vincristine (CAV) chemotherapy and were evaluable after a median follow-up of 7.5 months. Of the 29 patients, 25 had limited disease (LD) and 4 had extensive disease (ED). Three patients had a complete remission (CR), 19 had a partial remission (PR) and 7 were non-responders. All the complete responders are still alive at 8, 10 and 40.8 months. The median survival time (MST) of all the patients was 8.5 months. The patients with LD had an MST of 8.5 months while those with ED had an MST of 5.5 months. The chemotherapy regimen produced a total response rate and median survival comparable to those achieved with other regimens. The complete response rate, however, was low and needed to be improved with other approaches. In partial responders, continuation of chemotherapy beyond the 3 courses given for induction did not improve the CR rate. Drug resistance was a limiting factor to the efficacy of this CAV regimen. Prophylactic cranial irradiation is recommended. (auth.). 21 refs.; 2 figs.; 2 tabs

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

    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

    Full Text Available Objective: To study the effect of preoperative oral S-1 combined with regional intra-arterial chemotherapy on malignant molecule expression in locally advanced unresectable gastric cancer tissue. Methods: A total of 144 patients with locally advanced gastric cancer receiving surgical resection after neoadjuvant chemotherapy in our hospital between May 2012 and August 2015 were selected and randomly divided into experimental group who received preoperative oral S-1 combined with regional intra-arterial chemotherapy and control group who received preoperative intravenous systemic chemotherapy. The levels of serum tumor markers were determined after chemotherapy, and the expression levels of tumor suppressor genes and cell cycle-related molecules in tumor tissue were determined after surgical resection. Results: After neoadjuvant chemotherapy, the serum G-17, TK-1, CEA, CA19-9, CA12-5, CA72-4 and CK, CK-MB, ALT, AST levels of experimental group were significantly lower than those of control group; after surgical resection, the p16, p27, PTEN and TXNIP mRNA levels in tumor tissue of experimental group were significantly higher than those of control group while CyclinB2, CyclinD1, CyclinE, CDK1 and CDK2 mRNA levels were significantly lower than those of control group. Conclusions: Preoperative oral S-1 combined with regional intra-arterial chemotherapy can more effectively kill gastric cancer cells, reduce tumor load, inhibit cell cycle and promote cell apoptosis.

    The 2nd Department of Oral and Maxillofacial Surgery, Faculty of Dentistry Hospital, Iwate Medical University has performed radiation-combined intra-arterial chemotherapy as a preoperative treatment and subsequent mandibulectomy. During a 20 year-period from 1975 to 1994, clinical and histopathological examination of the above therapy was made for its effect and usefulness by using 15 primary cases of mandibular gingival squamous cell carcinoma, which were all identifiable. Roentgenological examination by bone resorptive pattern (invasive type, erosive type) and by bone resorptive depth (degree 0-III) revealed that early infiltration case and advanced case were predominant in the erosive type and the invasive type respectively. Histopathologically, the therapeutical effect of the radiation-combined intra-arterial chemotherapy on the tumor cells was examined using osteoclast, fibrous connective tissue, osteoblast, new bone, site of neoosteogenesis, and post-treatment site of residual tumor ceils as findings in the healing process. The histological therapeutic effect was good on well-differentiated type cases, and the histological effect on osteo-infiltrated region was as good as, or better than on soft tissue region. The cases with good histological therapeutic effect scarcely showed osteoclast, but showed remarkable hyperplasia of fibrous connective tissue, appearance of osteoblast and repair mechanism via neoosteogenesis. Invasive type tumor was persistent in the depth of the mandible, while erosive type tumor showed a tendency to be persistent in superficial layer. The results suggested that the application of the present radiation-combined intra-arterial chemotherapy to mandibular gingival squamous cell carcinoma is very useful leading to the improvement in radical curability of the tumor in its primary focus and the preservation of mandibular continuity in surgery.

    To investigate whether high-intensity focused ultrasound (HIFU) combined with microbubbles enhances the therapeutic effects of chemotherapy. 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. 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. High-intensity focused ultrasound combined with microbubbles enhances the therapeutic effects of gemcitabine chemotherapy in a pancreatic cancer xenograft model.

    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.) [de

    The hematologic immediate toxicity during radiotherapy for Hodgkin's disease was studied from a series of 72 patients who received 3 courses or more of chemotherapy before radiotherapy. The toxicity in the group of 36 of them who received total nodal irradiation (TNI) was the most important. Sixteen of the 28 TNI had irradiation interrupted, 12 of them began with inverted Y type. The blood cells count at the beginning of the treatment was crucial; only 16% of the patients had interruption of irradiation when the blood cells count was normal; on the other side, 63% had interruption when the blood cells count was abnormal (P [fr

    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.)

    Hematologic effects of granulocyte colony-stimulating factor (G-CSF) and erythropoietic (EPO) combination after priming intensive chemotherapy in the treatment of female breast carcinoma are presented. In a previous group treated with G-CSF alone, 36% of patients became anemic and to be transfused for correction of their anemia. To the present study consecutive patients with different stages of breast carcinoma were admitted. All were given priming intensive chemotherapy (epirubicin 150 m/m 2 and cyclophosphamide 1300 mg/m 2 ) followed by subcutaneous application of G-CSF at a dose of 5 μg/kg/day and EPO 250 IU/kg/day. In cases where leucocyte counts dropped below 1 x 10 9 /dm 3 and hemoglobin level fell to 85 g/dm 3 administration of growth factors was started. The therapy was stopped when normal leukocyte count reached 4 x 10 9 /dm 3 for G-CSF and hemoglobin level rose to 115 g/dm 3 for EPO. Our results show significant difference between MNC/Tl (min.), CD34 + cells/μl (min.), CFU-GM/ml (min.), BFU-E/ml (min) and MNC/μl (max.), CD34 + cells/μl (max.), CFU-GM/ml (max.), BFU-E/ml (ml) p + cells/μl, 23.4-fold for CFU-GM/ml and 28.7-fold increase for BFU-E/ml. Side effects were minimal, no infectious complications occurred, body temperature did not rise over 3 grad C and no corrections of anemia were needed. It is concluded that the administration of G-CSF plus EPO combination following intensive chemotherapy reduces hematologic toxicity and induces large amount of hemopoietic progenitors suitable for autologous transplantation in women with breast carcinoma.

    In this study, a novel type of hyaluronic acid (HA)-decorated nanostructured lipid carrier (NLC) was prepared and investigated as a light-triggered drug release and combined photothermal-chemotherapy for cancer treatment. Polyhedral gold nanoparticles (Au NPs) with an average size of 10 nm were synthesized and co-encapsulated with doxorubicin (DOX) in the matrix of NLCs with a high drug loading efficiency (above 80%). HA decoration was achieved by the electrostatic interaction between HA and CTAB on the NLC surface. A remarkable temperature increase was observed by exposing the Au NP-loaded NLCs to an NIR laser, which heated the samples sufficiently (above 40 °C) to kill tumor cells. The entrapped DOX exhibited a sustained, stepwise NIR laser-triggered drug release pattern. The biocompatibility of the NLCs was investigated by MTT assay and the cell viability was maintained above 85%, even at high concentrations. The intracellular uptake of free DOX and entrapped DOX, observed by confocal microscopy, revealed two distinct uptake mechanisms, i.e. passive diffusion and endocytosis, respectively. In particular, internalization of the HA-Au-DOX-NLCs was more extensively enhanced than the Au-DOX-NLCs, which was attributed to HA-CD44 receptor-mediated endocytosis. Meanwhile, the internalized NLCs successfully escaped from the lysosomes, increasing the intracellular DOX. The HA-Au-DOX-NLCs IC50 value decreased from 2.3 to 0.6 μg ml-1 with NIR irradiation at 72 h, indicating the excellent synergistic antitumor effect of photothermal-chemotherapy. The photothermal ablation was further confirmed by a live/dead cell staining assay. Thus, a combined photothermal-chemotherapy approach has been proposed as a promising strategy for cancer treatment.

    HDAC inhibitors, DNA alkylators and nucleoside analogs are effective components of combination chemotherapy. To determine a possible mechanism of their synergism, we analyzed the effects of HDAC inhibitors on the expression of drug transporters which export DNA alkylators. Exposure of PEER lymphoma T-cells to 15 nM romidepsin (Rom) resulted in 40%-50% reduction in mRNA for the drug transporter MRP1 and up to ~500-fold increase in the MDR1 mRNA within 32-48 hrs. MRP1 protein levels concomitantly decreased while MDR1 increased. Other HDAC inhibitors - panobinostat, belinostat and suberoylanilide hydroxamic acid (SAHA) - had similar effects on these transporters. The protein level of MRP1 correlated with cellular resistance to busulfan and chlorambucil, and Rom exposure sensitized cells to these DNA alkylators. The decrease in MRP1 correlated with decreased cellular drug export activity, and increased level of MDR1 correlated with increased export of daunorubicin. A similar decrease in the level of MRP1 protein, and increase in MDR1, were observed when mononuclear cells derived from patients with T-cell malignancies were exposed to Rom. Decreased MRP1 and increased MDR1 expressions were also observed in blood mononuclear cells from lymphoma patients who received SAHA-containing chemotherapy in a clinical trial. This inhibitory effect of HDAC inhibitors on the expression of MRP1 suggests that their synergism with DNA alkylating agents is partly due to decreased efflux of these alkylators. Our results further imply the possibility of antagonistic effects when HDAC inhibitors are combined with anthracyclines and other MDR1 drug ligands in chemotherapy.

    We retrospectively analyzed the effectiveness of preoperative treatment with combined chemotherapy, including cisplatin (CDDP) and carboplatin (CBDCA), and radiotherapy. Among 19 patients with oral squamous cell carcinoma, the primary site was the tongue in 13, the oral floor in 3, and the maxilla, lip, and gingiva in 1 case each. The clinical stage was 7 cases Stage II, 5 cases Stage III, and 7 cases Stage IV. Chemotherapy was administered intravenously using CDDP 50-80 mg (1 time) or CBDCA 150 mg once a week in a total dose of 300-750 mg, PEP 5 mg twice a week in a total dose of 40-60 mg, and 5-FU or Tegaful 300-600 mg in a total dose of 9.0-18.0 g. Radiotherapy was carried out with Lineac (5 times a week) in a total dose of 20-40 Gy/10-20 f/10-20 days. The clinical response to treatment was evaluated as CR 3 cases, PR 9 cases, and NC 6 cases. The response rate was 12/18 (66.7%) cases. Histologic effectiveness, evaluated according to the classification of Oohoshi and Shimosato, was Grade IV 11 cases, Grade III 3 cases, and Grade II 5 cases. The following adverse reactions were reported: stomatitis 19 cases, fever 13 cases, leukopenia 12 cases, loss of appetite 12 cases, and neutropenia 10 cases. Fourteen of the 19 patients (73.7%) have a good prognosis, without any signs of recurrence or metastasis. The results indicate that multidrug chemotherapy combined with radiotherapy is effective even for highly malignant carcinoma in the oral cavity. (author)

    The application of newer signaling pathway-targeted agents has become an important addition to chemotherapy in the treatment of advanced non-small cell lung cancer (NSCLC). In this study, we evaluated the efficacy and toxicities of PKC inhibitors combined with chemotherapy versus chemotherapy alone for patients with advanced NSCLC systematically. Literature retrieval, trials selection and assessment, data collection, and statistic analysis were performed according to the Cochrane Handbook 5.1.0. The outcome measures were tumor response rate, disease control rate, progression-free survival (PFS), overall survival (OS), and adverse effects. Five randomized controlled trials, comprising totally 1,005 patients, were included in this study. Meta-analysis showed significantly decreased response rate (RR 0.79; 95 % CI 0.64-0.99) and disease control rate (RR 0.90; 95 % CI 0.82-0.99) in PKC inhibitors-chemotherapy groups versus chemotherapy groups. There was no significant difference between the two treatment groups regarding progression-free survival (PFS, HR 1.05; 95 % CI 0.91-1.22) and overall survival (OS, HR 1.00; 95 % CI 0.86-1.16). The risk of grade 3/4 neutropenia, leucopenia, and thrombosis/embolism increased significantly in PKC inhibitors combination groups as compared with chemotherapy alone groups. The use of PKC inhibitors in addition to chemotherapy was not a valid alternative for patients with advanced NSCLC.

    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

    Radiation survival curves for some but not all human melanoma cells show broad shoulders and recovery of potentially lethal radiation damage (PLD), both in vitro and in situ as xenografts in mice. Studies have also demonstrated a significant hypoxic melanoma cell population. Chemotherapy and/or hyperthermia with radiation offers the potential for additive cell killing plus modification of the terminal slope and/or shoulder as a result of supra-additive killing via radiosensitization of hypoxic cells and/or post-irradiation inhibition of cellular recovery from PLD. Such interactions should provide a therapeutic gain factor, expecially if the long-term normal tissue damage is not based on PLD repair. Higher radiation doses per fraction warrant use of PLD recovery inhibitors and would accommodate a practical consideration for the use of fewer drug/heat doses. Peak heat or drug concentrations should probably be present just before and immediately following irradiation. This paper reviews the radiobiological experiments to support the rationale for the addition of chemotherapy and/or hyperthermia to melanoma. The author stresses the problems which remain including the paucity of appropriate preclinical experiments as well as clinical problems of tumor heterogeneity, pharmacokinetics and anatomy

    The menstrual cycle, pregnancies, and offspring were evaluated before and after initial combined radiation (RT) and chemotherapy with thiotepa, vinblastine, vincristine, procarbazine, and prednisone (TVPP), in 34 women between the ages of 18 and 44 (median 26.5 years) treated for Stage II and Stage III Hodgkin's disease. The median range of follow-up is 83.1 months (range 40.5-140). After therapy 94.1% (32/34) continued to menstruate. Two of the four patients over the age of 35 ceased to menstruate. All patients under the age of 35 continued to menstruate (30/30). Age at the time of diagnosis was the only factor affecting change in menses with a significant probability (p = .001) that women greater than 30 years of age will experience some change in menstrual pattern. Seventeen pregnancies occurred in 12 women after therapy; 2 had 4 elective abortions; 10 delivered 12 children with normal physical development; 1 will deliver six months from now. Twelve of thirteen patients who wanted to become pregnant have conceived. The ability to become pregnant and deliver normal children after intensive treatment with combined radiation and chemotherapy (RT/TVPP) was comparable to the patients' pretreatment record.

    Objective: To evaluate the safety of cetuximab combined with intensity-modulated radiotherapy (IMRT) plus concurrent cisplatin chemotherapy in locoregionally advanced nasopharyngeal carcinoma (NPC) in a Chinese multicenter clinical study. Methods: From July 2008 to April 2009, 100 Patients with primary stage III- IV b non-keratinizing NPC were enrolled. The planned dose of IMRT to gross tumor volume and positive cervical lymph nodes was 66.0-75.9 Gy and 60-70 Gy in 30-33 fractions. Cisplatin (80 mg/m 2 , q3 week (w)) and cetuximab (400 mg/m 2 one w before radiation, and then 250 mg/m 2 per w) were given concurrently. The adverse events (AEs) were graded according to common terminology criteria for adverse events v3.0. Results: The compliance of the entire group of patient was satisfactory. Actual median dose to gross tumor volume was 69.96 Gy, and the median dose to positive cervical lymph nodes was 68 Gy. Median dose of cisplatin was 133 mg, median first-dose of cetuximab was 690 mg, and median weekly dose was 410 mg. AEs were well tolerated and manageable, mainly consisting of acneiform skin eruptions,dermatitis and mucositis. Grade 4 mucositis was observed in 2% of the patients and no other grade 4 AEs were observed. Conclusions: The combined treatment modality of IMRT + concurrent chemotherapy + cetuximab in loco-regionally advanced NPC is well tolerated. (authors)

    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.

    Objective: To investigate the clinical value of two-dimensional speckle tracking echocardiography(2D-STE) combined with high-sensitive cardiac troponin T (hs-cTnT) in early detection of the cardiotoxicity induced by chemotherapy drug. Methods: Seventy-five non-Hodgkin's lymphoma patients who received the CHOP regimen were recruited in this study. Conventional echocardiography and 2D-STE were performed on these patients before chemotherapy, the second day after the third course of chemotherapy (during chemotherapy) and the second day after the last course of chemotherapy (after chemotherapy). The parameters included left ventricular ejection fraction (LVEF), global longitudinal strain (LS), global circumferential strain (CS) and global radial strain (RS). The serum hs-cTNT levels were tested simultaneously. Results: Three cycles of CHOP were completed in 30 patients and 6-8 cycles of CHOP were completed in 45 patients. The LVEF of 75 patients before, during and after chemotherapy was (63.8±2.6)%, (63.8±2.8)% and (64.0±3.3)%, respectively, without significant difference ( P =0.91). However, the LS of 75 patients before, during and after chemotherapy was (-18.5±1.7)%, (-16.5±1.9)% and (-16.0±1.6)%, respectively. The CS was (-20.9±2.9)%, (-19.3±3.5)% and (-19.2±3.2)%, respectively. The RS was (39.2±6.4)%, (35.3±5.2)% and (35.0±6.2)%, respectively. The hs-cTnT was (0.001 0±0.002 0)ng/ml, (0.006 3±0.008 9)ng/ml and (0.007 3±0.003 8)ng/ml, respectively. The LS, CS and RS were significantly decreased while hs-cTnT was significantly increased during chemotherapy when compared to those before chemotherapy (all of P chemotherapy were marginally different from those during chemotherapy (all of P >0.05). Moreover, T(LS-SD), T(CS-SD) and T(RS-SD) showed no significant difference before, during and after chemotherapy (all of P >0.05). The reduction of LS was positively associated with the enhancement of hs-cTnT after chemotherapy ( r =0.60, P effectively and

    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

    Abstract Antiangiogenic and antilymphangiogenic gene therapy with soluble vascular endothelial growth factor receptor-2 (VEGFR-2) and soluble VEGFR-3 in combination with chemotherapy is a potential new treatment for ovarian carcinoma. We evaluated the safety, toxicology, and biodistribution of intravenous AdsVEGFR-2 and AdsVEGFR-3 combined with chemotherapy in healthy rats (n=90) before entering a clinical setting. The study groups were: AdLacZ and AdLacZ with chemotherapy as control groups, low dose AdsVEGFR-2 and AdsVEGFR-3, high dose AdsVEGFR-2 and AdsVEGFR-3, combination of low dose AdsVEGFR-2 and AdsVEGFR-3 with chemotherapy, combination of high dose AdsVEGFR-2 and AdVEGFR-3 with chemotherapy, and chemotherapy only. The follow-up time was 4 weeks. Safety and toxicology were assessed by monitoring the clinical status of the animals and by histological, hematological, and clinical chemistry parameters. For the biodistribution studies, quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) and enzyme-linked immunosorbent assay (ELISA) were used. Low dose (2×10(10) vp) AdsVEGFR-2 and AdsVEGFR-3 gene therapy was well tolerated, even when gene therapy was combined with chemotherapy. Notably, only transient elevation of liver enzymes and mild regenerative changes were seen in liver after the gene transfer in the groups that received high doses (2×10(11) vp) of AdsVEGFR-2 and AdsVEGFR-3 with or without chemotherapy. No life-threatening adverse effects were noticed in any of the treatment groups. The highest protein concentration of soluble VEGFR-2 (sVEGFR-2) in circulation was seen 1 week after the gene transfer. The combination of chemotherapy to gene therapy seemed to prolong the time of detectable transgene protein at least 1 week in the circulation. The expression of AdsVEGFR-2 and AdsVEGFR-3 transgenes was mainly seen in the liver and spleen as detected by qRT-PCR. According to these results, AdsVEGFR-2 and AdsVEGFR-3 gene therapy combined with

    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 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 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

  4. Metronomic chemotherapy.

    Chemotherapy drugs are usually administered at doses that are high enough to result in an obligatory break period to allow for the observation of potential side effects and institution of supportive care, if required. In recent years, efforts to administer chemotherapy on a more continuous basis, with a much shorter break period, or none at all, have received increased interest, and the practice has come to be known as metronomic chemotherapy. The basis for success with this currently investigational approach may be rooted in continuous drug exposure to susceptible cancer cells, inhibition of tumor blood vessel growth-a process known as tumor angiogenesis, and/or alterations in tumor immunology. Increased benefit also appears to occur when metronomic chemotherapy is used in combination with newer, targeted antiangiogenic agents, and therefore represents a promising approach to combination therapy, particularly as targeted oncology drugs make their way into veterinary oncology applications. There is still much to be learned in this field, especially with regard to optimization of the proper drugs, dose, schedule, and tumor applications. However, the low cost, ease of administration, and acceptable toxicity profiles potentially associated with this therapeutic strategy make metronomic chemotherapy protocols attractive and suitable to veterinary applications. Preliminary clinical trial results have now been reported in both human and veterinary medicine, including adjuvant treatment of canine splenic hemangiosarcoma and incompletely resected soft tissue sarcoma, and, further, more powerful studies are currently ongoing.

    A male patient in his 50s underwent distal gastrectomy for gastric cancer. In operation, there was no peritoneal dissemination. But peritoneal lavage cytology revealed positive peritoneal dissemination. Thus, we set an intraperitoneal infuser port to this patient. On specimen, a type-3 tumor was located in the gastric lesser of antrum to angle. Microscopic examination of specimens revealed a signet ring cell carcinoma and poorly differentiated adenocarcinoma under serosa, and positive of lymph node metastasis. The diagnosis was pT4N2M1P0CY1H0, Stage IV( Japanese classification of gastric carcinoma The 14 Edition). CDDP was administered through the infuser port (on day 7, a first dose of 60 mg/m2 and 30 mg/m2 for second) combined with oral administration of S-1 (100 mg/body) for two weeks, with one week of drug withdrawal. This chemotherapy was repeated for 11 courses. After that, peritoneal lavage cytology became negative. S-1 oral administration was continued for four years, and this patient has been well for five years and six months after the surgery. Therefore, it is suggested that intraperitoneal chemotherapy with cisplatin is an effective treatment for microscopical peritoneal dissemination.

    Fifty patients with invasive bladder carcinoma were treated with neoadjuvant intra-arterial chemotherapy using doxorubicin or pirarubicin, and this was combined with low dose radiotherapy. All of 50 patients were evaluated for clinical and histological efficacy. Twenty-nine of 50 (58%) patients achieved a clinically complete remission (CR) and 17 of 50 (34%) achieved a clinically partial remission (PR). Twenty-eight of 50 (56%) achieved a histological CR and 13 of 50 (26%) achieved a histological PR. The patients who underwent bladder preservation operations after this treatment and were followed up for longer than 3 years were evaluated for long-term results. The 5-year survival for 35 patients in this group was 74.1%. The 5-year survival for patients with a clinical CR was 93.3%, and for patients with a clinical PR it was 45.3%. The survival for patients with a histological CR was 93.3%, and for patients with a histological PR, it was 85.7%. This study suggests that neoadjuvant intra-arterial chemotherapy plus radiotherapy is a useful regimen that could become the treatment of first choice for patients with invasive bladder carcinoma. Patients who achieved a histological CR or PR with this regimen, might be able to retain the function of their bladders. (author)

    Objective: To evaluate the efficacy of large spot indirect ophthalmoscopy laser alone or combined with systemic chemotherapy in the treatment of early and middle stage retinoblastoma. Methods: Retrospective series case study. Clinical data of 21 patients (22 eyes) who were diagnosed as retinoblastoma (RB) in Peking University People's Hospital from March 2009 to August 2014 were collected. Medical and family history, ocular ultrasound, orbital and cranial MRI or CT examination of RB Children were detailed recorded. Ocular examination and laser treatment were performed under general anesthesia, once every 3-4 weeks until the tumor was under control. The observation period was at least 3 months after the last treatment. The ocular examination included intraocular pressure measurement, anterior segment and fundus examination and the fundus photography with Retcam. Laser therapeutic instrument was large spot indirect ophthalmoscopy laser of 810nm wavelength. Results: Of the 21 children, 16 were male and 5 were female. The range of age was 3 to 82 months averaged 17.3 months. Among 22 eyes, four with small tumor, eight with medium tumor, and ten with large tumor. Two eyes underwent laser treatment only and 20 eyes underwent laser treatment combined with systemic chemotherapy. During the average observation period of 33.9 months, 15 tumors were treated successfully, but 7 failed. The total success rate was 68.2%. The number and success rate of small, medium and large tumor eyes were 4 (100%), 5 (62.5%) and 5 (50%), respectively. There was one case of tumor brain metastases, and the classification of contralateral eye of the child was E phase. Iris burns happened in one eye, obvious vitreous proliferation in one eye and mild vitreous hemorrhage occurred in two eyes, which did not affect the treatment of laser. However, obvious tumor hemorrhage happened in two eyes and affected laser therapy. There was no complicated cataract, iatrogenic retinal hole and tumor intravitreal

    The impact of combining epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and chemotherapy as first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC) remains controversial. Therefore, randomized trials that compared this combined regimen with chemotherapy or EGFR-TKIs monotherapy were included for this meta-analysis. We used published hazard ratios (HRs), if available, or derived treatment estimates from other survival data. Pooled estimates of treatment efficacy of the combined regimen in the entire unselected population and selected patients by EGFR-mutation status and smoking history were calculated. Eight trials eventually entered into this meta-analysis, including 4585 patients. Overall, the combined regimen significantly delayed disease progression (HR = 0.81, 95% CI 0.69-0.95, P = 0.01); subgroup analysis showed significantly higher progression free survival advantages in Asian patients (Pchemotherapy (P = 0.02). In selected patients by EGFR-mutation, both mutation positive (HR = 0.48, 95% CI 0.28-0.83, P = 0.009) and negative (HR = 0.84, 95% CI 0.72-0.98, P = 0.02) patients gained progression free survival benefit from the combined regimen, albeit the magnitude of benefit was marginally larger in mutation positive patients (P = 0.05). In selected patients by smoking history, never/light smokers achieved a great progression free survival benefit from the combined regimen (HR = 0.51, 95% CI 0.35-0.74, P = 0.0004). Unfortunately, the combined regimen had no significant impact on overall survival, irrespective of ethnicity, dose schedules or EGFR-mutation status. Severe anorexia (RR = 2.01, 95% CI 1.11-3.63; P = 0.02) and diarrhea (RR = 2.70, 95% CI 1.94-3.76; Pchemotherapy deserved to be considered in the future, although it is not approved for advanced NSCLC at the moment.

    Few studies have been published on the safety and feasibility of synchronous use of peptide receptor radionuclide therapy (PRRNT), as source of internal radiation therapy, in combination with chemotherapy. In this study we reported a 53-year-old man with stage IV Merkel cell carcinoma (MCC), who underwent synchronous internal radiation therapy and chemotherapy. Based on presumable poor prognosis with chemotherapy only, functional similarities of MCC with other neuroendocrine tumors and available evidence of effectiveness and safety of synchronous use of external beam radiation therapy and chemotherapy in treatment of high-risk MCC patients, our interdisciplinary neuroendocrine tumor board recommended him to add PRRNT to his ongoing chemotherapy. He received 2 courses of 177 Lu-DOTATATE(1, 4, 7, 10-Tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid-1-D-Phe1-Tyr3-Thr8-octreotide) in combination with ongoing 8 cycles of liposomal doxorubicin based on standard protocols. Response to therapy was evaluated by 18 F-fluorodeoxyglucose ( 18 F-FDG) and 68 gallium-somatostatin-receptor PET/CT. There was an impressive improvement of the clinical symptoms. However, follow-up positron emission tomography (PET)/CT studies showed mixed pattern of response. Synchronous use of PRRNT and radiosensitizing chemotherapy seems safe and feasible in high risk MCC patients, however, further prospective studies and clinical trials are warranted to provide reliable evidence of possible pitfalls and effectiveness of PRRNT and 68 Ga-somatostatin-receptor PET/CT in the management of MCC.

    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.

    Objective. To investigate the effects of Jianpi Bushen (JPBS), a traditional Chinese medicine that is used to invigorate the spleen and tonify the kidney, combined with chemotherapy for the treatment of gastric cancer. Methods. Literature retrieval was performed in PubMed, EMBASE, Cochrane Library, MEDLINE, CNKI, Wanfang Data Information Site, and VIP from inception to October 2017. Randomized controlled trials to evaluate the effects of JPBS combined with chemotherapy were identified. The primary reported outcomes were KPS (Karnofsky Performance Status), clinical curative efficiency, immune function, blood system, and nonhematologic system. Review Manager 5.3 (RevMan 5.3) was used for data analysis, and the quality of the studies was also appraised. Results. A total of 26 studies were included with 3098 individuals. The results of the meta-analysis indicated that treatment of gastric cancer with the combination of JPBS and chemotherapy resulted in better outcomes compared to chemotherapy alone. Conclusion. Evidence from the meta-analysis suggested that JPBS combined with chemotherapy has a positive effect on gastric cancer treatment. However, additional rigorously designed and large sample randomized controlled trials are required to confirm the efficacy and safety of this treatment. PMID:29675052

    The interactions between drugs and radiation have been observed. In normal tissues, there is evidence both for sensitization and protection, and clear examples of interactive phenomena in tumors do exist. The term ''interaction'' is defined as the situation in which the treatment with one agent modifies the response of cells (tumor or normal) to the treatment with a second agent. Many interactive mechanisms can be envisaged: for instance, drugs modifying the initial events in radiation absorption; repair inhibition; cell-cycle progression phenomena; radiation modifying drug access and drug-induced reoxygenation. ''Spatial cooperation'' is suggested for the situation in which the chemotherapy and radiotherapy given to the diseases in different anatomical sites lead to the therapeutic result that exceeds the results by the separate treatment. The administration of one cytotoxic agent to an animal or a patient would decrease tolerance to the subsequent treatment with another cytotoxic agent. Cytosine arabinoside (Ara-C) is one of the most effective agents. When it was given to mice in a single well-tolerated dose of 200 mg/kg, the proportion of animals that survived wholebody irradiation of 1000 rad was increased from zero to approximately 90%. The timing was critical, and the optimum interval was 2 - 3 days. Under some circumstances, the positive interaction between the tumor cell-killing effects of drugs and radiation can be achieved. Unfortunately, the dose-effect curves are often not linear. (Yamashita, S.)

    Objective: To investigate the associated effect of 125 I 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 125 I permanent implantation combined with DP regimen (docetaxel 60 mg/m 2 + cisplatinum 75 mg/m 2 ), while the control group received only DP chemotherapy. According to the TPS, the treatment group received CT-guided percutaneous implantation of 125 I seeds with a particle activity of 2.22 ×10 7 -2.59 × 10 7 Bq. The prescribed dose was in the range of 90-110 Gy and the postoperatively matched peripheral dose (mPD) and D 90 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 D 90 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

    The in vitro microculture kinetic (MiCK) apoptosis assay has been used to predict single or combination chemotherapy response in leukemia patients. This feasibility study addressed MiCK in endometrial cancer specimens. Endometrial cancer specimens from total abdominal hysterectomies were processed at a central laboratory. Single cell suspensions of viable endometrial cancer cells were plated in individual wells. Single and combination regimens were tested: combinations of doxorubicin, cisplatin, and paclitaxel and carboplatin and paclitaxel (Gynecologic Oncology Group [GOG] 209 endometrial cancer phase III trial arms) as well as single agent testing with paclitaxel, carboplatin, doxorubicin, cisplatin, ifosfamide, and vincristine (active agents in GOG trials). Apoptosis was measured continuously over 48 hours. Fifteen of nineteen patients had successful assays. The highest mean chemo sensitivity was noted in the combination of cisplatin, doxorubicin, and paclitaxel with lower mean chemosensitivity for carboplatin and paclitaxel. Combination chemotherapy had higher chemosensitivity than single drug chemotherapy. However, in 25% of patients a single drug had higher chemosensitivity than combination chemotherapy. As single agents, ifosfamide, cisplatin, and paclitaxel had the highest kinetic unit values. Using a panel of agents simulating clinical dose regimens, the MiCK assay was feasible in evaluating in vitro chemosensitivity of endometrial cancer. MiCK assay results correlated with GOG clinical trial results. However, 25% of patients might be best treated with single agent chemotherapy selected by MiCK. Ifosfamide, cisplatin, and paclitaxel appear to have high activity as single agents. MiCK may be useful in future new drug testing and individualizing endometrial cancer patient's chemotherapy management.

    The concurrent administration of chemotherapy and epidermal growth factor receptor‑tyrosine kinase inhibitors (EGFR‑TKIs) has previously produced a negative interaction and failed to confer a survival benefit to non‑small cell lung cancer (NSCLC) patients compared with first‑line cytotoxic chemotherapy. The present study aimed to investigate the optimal schedule of the combined treatment of cisplatin/paclitaxel and icotinib in NSCLC cell lines and clarify the underlying mechanisms. HCC827, H1975, H1299 and A549 human NSCLC cell lines with wild‑type and mutant EGFR genes were used as in vitro models to define the differential effects of various schedules of cisplatin/paclitaxel with icotinib treatments on cell growth, proliferation, cell cycle distribution, apoptosis, and EGFR signaling pathway. Sequence‑dependent antiproliferative effects differed among the four NSCLC cell lines, and were not associated with EGFR mutation, constitutive expression levels of EGFR or downstream signaling molecules. The antiproliferative effect of cisplatin plus paclitaxel followed by icotinib was superior to that of cisplatin or paclitaxel followed by icotinib in the HCC827, H1975, H1299 and A549 cell lines, and induced more cell apoptosis and G0/G1 phase arrest. Cisplatin and paclitaxel significantly increased the expression of EGFR phosphorylation in the HCC827 cell line. However, only paclitaxel increased the expression of EGFR phosphorylation in the H1975 cell line. Cisplatin/paclitaxel followed by icotinib influenced the expression of p‑EGFR and p‑AKT, although the expression of p‑ERK1/2 remained unchanged. The results suggest that the optimal schedule of the combined treatment of cisplatin/paclitaxel and icotinib differed among the NSCLC cell lines. The results also provide molecular evidence to support clinical treatment strategies for NSCLC patients.

    Local immunological factors are thought to be parenchymal reaction of normal and tumor tissues. Those were studied by morphological changes of angiographic findings and histological methods which included photomicroscopic, electromicroscopic and enzymic-histochemical studies. It was demonstrated that the effect of radiotherapy depended on not only local blood supply but also parenchymal reaction of the host. Especially, the parenchymal reaction at 2000 or 3000 rad irradiation was regarded as nonspecific tissue repair as well as immunological protective reactions brought about by enhancement of the tumor antigenicity. It was proved that T-cell system played a main role in this parenchymal reaction. Changes of systemic immunological factors were studied in 17 laryngeal cancer and 80 lung cancer patients treated by radiotherapy alone or radiotherapy with combined chemotherapy. Due to the fact that damages of the host before treatment were not so serious and integral dose given to the patients was a little in cases of laryngeal cancer immunological parameters such as absolute lymphocyte counts, PHA and PPD skin test activities, lymphocyte blastoid transformation with PHA, PWM and Con A, did not show significant change. However, as for lung cancer treated by large integral dose irradiation combined with chemotherapy, immunological parameters were depressed in inverse proportion to the dose of irradiation and chemotherapeutic agents. Moreover T-cell subsets (early E-rosette forming cells, IgG Fc-receptor positive cells), lymphocyte sub-populations, ADCC activity, serum immunoglobulins, and serum protein were also investigated in cases of lung cancer. We have evaluated the immunological parameters in relation to the therapeutic effect. As a result, it was suggested that several parameters should be needed to forecast the prognosis. (author)

    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

    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.

    The aim of this study was to retrospectively compare the treatment efficacy of systemic chemotherapy combined with sequential CT-guided radiofrequency ablation (Chemo-RFA) to chemotherapy alone (Chemo-only) in the management of nasopharyngeal carcinoma (NPC) with liver metastasis. Between 2003 and 2011, 328 NPC patients diagnosed with liver metastasis at Sun Yat-sen University Cancer Center were enrolled. One-to-one matched pairs between Chemo-RFA group with the Chemo-only group were generated using propensity score matching. The associations of treatment modality with overall survival (OS) and progression-free survival (PFS) were determined by Cox regression. Of the patients enrolled, 37 patients (11.8 %) received combined treatment, 291 (82.2) received chemotherapy alone. The patients in Chemo-RFA group were more frequently classified as lower number (≤3) of liver metastatic lesions (Poligometastasis in liver, and should be considered if the ablation is technically feasible.

    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.

    In Japan, the combination of anthracycline and cytarabine(Ara-C)is a standard therapy for acute myelogenous leukemia(AML). Chemotherapy-induced nausea and vomiting(CINV)are frequently reported as side effects related to the administration of these regimens. In our hospital, patients received prophylactic granisetron at a dose of 3 mg daily during chemotherapy. However, granisetron is known to induce constipation as a side effect. The present study evaluated the efficacy of a single dose of granisetron administered throughout the entire period of chemotherapy in AML patients receiving anthracycline and Ara-C combination therapy, and also examined the incidence of constipation during chemotherapy. From July 2008 to December 2010, all patients with AML treated using anthracycline and Ara-C combination therapy were registered in the study. This retrospective study investigated the patients' background and the incidence of CINV and constipation from the patients' records. The efficacy of granisetron was measured on each day using the complete regression(no vomiting and no rescue medication; CR)rate. A total of 45 patients were included in the study(27 male; 18 female), and received a total 68 courses(56 of induction therapy; 12 of consolidation therapy)of the regimens. The CR rate and the incidence of constipation on the final day of chemotherapy were 61. 8% and 63. 2%, respectively. As the duration of chemotherapy increased, the CR rate tended to decrease, whereas the incidence of constipation tended to increase. The CR rate in this study was 61. 8%, thus indicating that there is still room for improvement. The combination of dexamethasone and a neurokinin-1 receptor antagonist, or the changeover from granisetron to palonosetron could therefore increase the CR rate.

    Tumor-induced angiogenesis leads to the development of leaky tumor vessels devoid of structural and morphological integrity. Due to angiogenesis, elevated interstitial fluid pressure (IFP) and low blood perfusion emerge as common properties of the tumor microenvironment that act as barriers for drug delivery. In order to overcome these barriers, normalization of vasculature is considered to be a viable option. However, insight is needed into the phenomenon of normalization and in which conditions it can realize its promise. In order to explore the effect of microenvironmental conditions and drug scheduling on normalization benefit, we build a mathematical model that incorporates tumor growth, angiogenesis and IFP. We administer various theoretical combinations of antiangiogenic agents and cytotoxic nanoparticles through heterogeneous vasculature that displays a similar morphology to tumor vasculature. We observe differences in drug extravasation that depend on the scheduling of combined therapy; for concurrent therapy, total drug extravasation is increased but in adjuvant therapy, drugs can penetrate into deeper regions of tumor.

    Drug delivery systems combined multimodal therapy strategies are very promising in cancer theranostic applications. In this work, a new drug-delivery vehicles based on human serum albumin (HSA)-coated gold nanorods (GNR/PSS/HSA NPs) was developed. The success of coating was verified by transmission electron microscopy (TEM), zeta potential and fourier transform infrared spectroscopy (FTIR). Furthermore, it is demonstrated that doxorubicin (DOX) is successfully loaded among multilayered gold nanorods by the electrostatic and hydrophobic force, and DOX@GNR/PSS/HSA NPs were highly biocompatible and stable in various physiological solutions. The NPs possess strong absorbance in nearinfrared (NIR) region, and high photothermal conversion efficiency for outstanding photothermal therapy applications. A bimodal drug release triggered by proteinase or NIR irradiation has been revealed, resulting in a significant chemotherapeutic effect in tumor sites because of the preferential drug accumulation and triggered release. Importantly, the in vitro and in vivo experiments demonstrated that DOX@GNR/PSS/HSA NPs, which combined photothermal and chemotherapy for cancer therapy, revealing a remarkably superior synergistic anticancer effect over either monotherapy. All these results suggested a considerable potential of DOX@GNR/PSS/HSA NPs nano-platform for antitumor therapy.

    Despite advances in standard therapies, the survival of glioblastoma multiforme (GBM) patients has not improved. Limitations to successful translation of new therapies include poor delivery of systemic therapies and use of simplified preclinical models which fail to reflect the clinical complexity of GBMs. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis specifically in tumor cells and we have tested its efficacy by on-site delivery via engineered stem cells (SC) in mouse models of GBM that mimic the clinical scenario of tumor aggressiveness and resection. However, about half of tumor lines are resistant to TRAIL and overcoming TRAIL-resistance in GBM by combining therapeutic agents that are currently in clinical trials with SC-TRAIL and understanding the molecular dynamics of these combination therapies are critical to the broad use of TRAIL as a therapeutic agent in clinics. In this study, we screened clinically relevant chemotherapeutic agents for their ability to sensitize resistant GBM cell lines to TRAIL induced apoptosis. We show that low dose cisplatin increases surface receptor expression of death receptor 4/5 post G2 cycle arrest and sensitizes GBM cells to TRAIL induced apoptosis. In vivo, using an intracranial resection model of resistant primary human-derived GBM and real-time optical imaging, we show that a low dose of cisplatin in combination with synthetic extracellular matrix encapsulated SC-TRAIL significantly decreases tumor regrowth and increases survival in mice bearing GBM. This study has the potential to help expedite effective translation of local stem cell-based delivery of TRAIL into the clinical setting to target a broad spectrum of GBMs. © 2014 AlphaMed Press.

    5-chloro-2,4-dihydroxypyridine (gimeracil) is a component of the oral fluoropyrimidine derivative S-1. Gimeracil was originally added to S-1 to yield prolonged 5-fluorouracil (5-FU) concentrations in serum and tumor tissues by inhibiting dihydropyrimidine dehydrogenase, which degrades 5-FU. We previously demonstrated that gimeracil enhances the efficacy of radiotherapy through the suppression of homologous recombination (HR) in DNA double strand repair. The goal of this paper was to examine the effects of gimeracil on the sensitivity of anticancer drugs and hyperthermia in order to obtain effective radiosensitization. Various cell lines, including DLD 1 (human colon carcinoma cells) and cells deficient in HR or nonhomologous end-joining (NHEJ), were used in clonogenic assays. The survival of these cells after various treatments (e.g., drug treatment, heat treatment, and radiation) was determined based on their colony-forming ability. Gimeracil enhanced cell-killing effects of camptothecin (CPT), 5-FU, and hydroxyurea. Gimeracil sensitized effects of CPT or 5-FU to cells deficient in HR or NHEJ to a similar extent as in other cells (DLD1 and a parent cell), indicating that its sensitizing mechanisms may be different from inhibition of HR or NHEJ. Combination of gimeracil and CPT or 5-FU sensitized radiation more effectively than each modality alone. Gimeracil also enhanced heat sensitivity at 42 C or more. The degree of heat sensitization with gimeracil increased as the temperature increased, and the combination of gimeracil and heat-sensitized radiation was more effective than each modality alone. Gimeracil enhanced sensitivity of CPT, 5-FU, and hyperthermia. Combination of these modalities sensitized radiation more efficiently than each modality alone.

    The effectiveness of a tablet containing a combination of rifampicin, isoniazid and pyrazinamide (Rifater; Mer-National) in the treatment of pulmonary tuberculosis was examined by comparing it with a previously evaluated four-drug regimen. Of 150 black goldminers with a first case of pulmonary tuberculosis, 69 were randomly allocated to receive the combination tablet (RHZ), 5 tablets per day on weekdays for 100 treatment-days, and 81 the four-drug regimen (streptomycin, rifampicin, isoniazid and pyrazinamide) (RHZS). Non-compliance was detected in 42% of the RHZ group and in 16% of the RHZS group. Two patients in the RHZ group and 4 in the RHZS group had to have their treatment altered because routine investigations revealed drug-resistant mycobacteria. Treatment was unsuccessful in 10 patients in the RHZ group, with 4 men failing to complete the regimen and being lost to follow-up, 3 cases of failure of conversion of sputum on the regimen, and 3 relapses. The results for the RHZS group were similar, with 4 failures to complete the regimen, 2 treatment failures and 4 relapses. Evaluation of RHZ showed it to be comparable with a previously evaluated, successful short-course regimen (RHZS). The high incidence of non-compliance probably reflects reduced supervision of this wholly oral regimen.

    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

    Twenty-one patients with stage III M 0 non-oat cell bronchogenic carcinoma confined to the thorax were randomized to receive either intrapleural BCG (10 7 cfu, Tice strain) or intrapleural saline 3 weeks prior to beginning combined irradiation and chemotherapy. Radiation to the primary tumor and regional nodes was given at a dose of 3,000 rad in ten sessions and was followed in 7-14 days by CAMP chemotherapy (cyclophosphamide, adriamycin, methotrexate, and procarbazine) for a planned duration of 6 months. Isoniazid, 300 mg/day, was given to all patients for 3 months starting 1 week after intrapleural therapy. There were no significant differences in pretreatment prognostic factors or in response to radiation therapy. The patients receiving intrapleural BCG in addition to radiation and chemotherapy had a median survival of 18 weeks, significantly shorter than that for the patients receiving intrapleural saline (54 weeks, P=0.017).

    Four patients with urinary bladder carcinoma were treated by combination therapy which consisted of hyperthermia vesical irrigation of two anticancer drugs (peplomycin and picibanil), intravesical instillation of those drugs and radiation. Following the therapeutic method we planned, 40 mg of peplomycin and 10 KE of picibanil in 1,500 ml of sterile distilled water was irrigated at 42 to 43/sup 0/C into the bladder for 3 hours; 40 mg of peplomycin and 10 KE of picibanil in 40 ml of sterile distilled water was instilled into the bladder; and, the focus was irradiated with /sup 60/Co to a focal dose of 200 rad 30 minutes later. This pattern of treatment was repeated once a week, 3 to 5 times in total. On the days this pattern was not taken, 5 KE of picibanil in 20 ml of sterile distilled water was instilled into the bladder cavity. Complete response was observed in one patient and partial response in 3 patients. The side effect was temporary irritable bladder symptom. (author).

    At present the addition of thoracic irradiation to combination chemotherapy is a standard treatment for limited staged small cell ling cancer. However, there is still controversy about the optimum timing of chest irradiation. We conducted a phase II study of etoposide (VP-16)-ifosfamide-cisplatin (VIP) combination chemotherapy plus early concurrent thoracic irradiation for the patients with previously untreated limited small cell lung cancer in order to assess if the treatment modality could improve the response rate and the toxicity. Forty-four patients with limited small cell lung cancer were treated with etoposide-ifosfamide-cisplatin and concurrent thoracic irradiation. Combination chemotherapy consisted of etoposide 100 mg/m 2 (on day 1-3), ifosfamide 1000 mg/m 2 (on days 1 and 2) and cisplatin 100 mg/m 2 (on day 1). Concurrent thoracic irradiation consisted of a total of 4000 cGy over 4 weeks starting on the first day of the first chemotherapy. All patients who showed a complete response were given prophylactic cranial irradiation for 2.5 weeks. Forty-four of the 49 patients who entered the study from May 1994 to August 1998 were evaluable. The median age was 59 years and 40 patients had a performance status of 0 or 1. The median survival time was 22.5 months. Twenty-eight patients (62%) showed a complete response and 16 (38%) a partial response. Twenty-four patients (54%) developed grade 3 or 4 neutropenia; there was a 9% RTOG score 3 or 4 esophagitis. VIP combination chemotherapy and early concurrent thoracic irradiation for patients with limited stage small cell lung cancer revealed excellent antitumor response with tolerable toxicity. (author)

    A 68-year-old man was referred to our outpatient clinic with left renal cell cancer and bladder cancer. He had undergone combination therapy comprising chemotherapy plus radiation therapy following radical orchiectomy for testicular cancer at the age of 48 years. The right testis could be felt within the scrotum, however the left testis could not. Blood tests showed no abnormality in regard to testicular tumor markers. Urine cytology was class V. Computed tomography revealed a 3.0 x 3.4 cm mass in the left kidney and a 4.5 x 1.5 cm mass in the left wall of the bladder. We made it a priority to treat the bladder cancer which was strongly suspected to be invasive cancer. At first the patient underwent radical cystectomy. Then left partial nephrectomy was carried out. Our case would appear to be the 24th case of triple primary urogenital cancer in Japan that consisted of left testicular cancer, left renal cancer and bladder cancer. Our case was also thought to be a case of secondary cancer that developed following treatment for testicular cancer. (author)

    Thermal therapy combined with chemotherapy is one of the advanced and efficient methods to eradicate cancer. In this work, we fabricated magnetically actuated smart textured (MAST) fibrous systems and studied their candidacy for cancer treatment. The polycaprolactone-Fe 3 O 4 based MAST fibers were fabricated using electrospinning technique. These MAST fibrous systems contained carbogenic quantum dots as a tracking agent and doxorubicin hydrochloride anticancer drug. Additionally, as fabricated MAST fibrous systems were able to deliver anticancer drug and heat energy simultaneously to kill HeLa cells in a 10 min period in vitro. After treatment, the metabolic activity and morphology of HeLa cells were analyzed. In addition, the mechanism of cell death was studied using flow cytometry. Interestingly, the navigation of these systems in the fluid can be controlled with the application of gradient magnetic field. © 2016 Wiley Periodicals, Inc.

    The investigative therapy for a senior patient after radical subtotal gastroesophagectomy for regional lymph node and proximal esophagus metastasized adenocarcinoma (stage IIIA, T3, N 1 M0) of the cardioesophageal junction is reported. The case has several unusual features: (1) the patient is the author and is not a physician; (2) in the absence of codified postsurgical treatment, he used his academic biomedical background, commercial associations, and international contacts to find and prioritize six clinically tested options for investigative postsurgical therapy; (3) after unsuccessful efforts to append ongoing clinical trials of new immunotherapies for breast adenocarcinoma (the first two therapy options), an innovative protocol was designed and gained allowance by the U.S. Food and Drug Administration for his use of combined nonspecific immunotherapy and chemotherapy based on extensive trials in South Korea that showed the synergistic effect of the two postsurgical therapies used together. A potent, new, nonspecific immunostimulant (DetoxPC) was injected subcutaneously in 10 diminishing doses during 105 weeks. Two standard chemotherapeutic drugs (5-fluorouracil and mitomycin-C) were injected intravenously in six equal doses during three weeks. Five years after the surgery, the patient enjoys good health without signs or symptoms of recurrence or metastasis. He discusses his perspectives on future clinical trials and on a patient actively pursuing investigative postsurgical therapy for a malignancy when otherwise poor survival is indicated.

    To determine the place of single-agent paclitaxel compared with nonanthracycline combination chemotherapy as front-line therapy in metastatic breast cancer. Patients with previously untreated metastatic breast cancer were randomized to receive either paclitaxel 200 mg/m(2) intravenously (IV) over 3 hours for eight cycles (24 weeks) or standard cyclophosphamide 100 mg/m(2)/d orally on days 1 to 14, methotrexate 40 mg/m(2) IV on days 1 and 8, fluorouracil 600 mg/m(2) IV on days 1 and 8, and prednisone 40 mg/m(2)/d orally on days 1 to 14 (CMFP) for six cycles (24 weeks) with epirubicin recommended as second-line therapy. A total of 209 eligible patients were randomized with a median survival duration of 17.3 months for paclitaxel and 13.9 months for CMFP. Multivariate analysis showed that patients who received paclitaxel survived significantly longer than those who received CMFP (P =.025). Paclitaxel produced significantly less severe leukopenia, thrombocytopenia, mucositis, documented infections (all P = .07). Initial paclitaxel was associated with significantly less myelosuppression and fewer infections, with longer survival and similar quality of life and control of metastatic breast cancer compared with CMFP.

    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.

    An advanced nanocomposite consisting of an encapsulated porous silicon (PSi) nanoparticle and an acid-degradable acetalated dextran (AcDX) matrix (nano-in-nano), was efficiently fabricated by a one-step microfluidic self-assembly approach. The obtained nano-in-nano PSi@AcDX composites showed improved surface smoothness, homogeneous size distribution, and considerably enhanced cytocompatibility. Furthermore, multiple drugs with different physicochemical properties have been simultaneously loaded into the nanocomposites with a ratiometric control. The release kinetics of all the payloads was predominantly controlled by the decomposition rate of the outer AcDX matrix. To facilitate the intracellular drug delivery, a nona-arginine cell-penetrating peptide (CPP) was chemically conjugated onto the surface of the nanocomposites by oxime click chemistry. Taking advantage of the significantly improved cell uptake, the proliferation of two breast cancer cell lines was markedly inhibited by the CPP-functionalized multidrug-loaded nanocomposites. Overall, this nano-in-nano PSi@polymer composite prepared by the microfluidic self-assembly approach is a universal platform for nanoparticles encapsulation and precisely controlled combination chemotherapy.

    Objective: To compare the efficacy between bronchial artery infusion (BAI) chemotherapy plus radiation therapy and systemic chemotherapy plus radiation for locally advanced non-small cell lung cancer (NSCLC). Methods: One hundred and twenty-one patients with stage III NSCLC were randomized into treatment group (58 cases) and control group (63 cases). In the treatment group, all patients were administered with BAI for 2-3 sessions, followed by irradiation 4-7 days after BAI. In the control group, altogether 4-6 cycles of standard systemic chemotherapy were given. Radiation was delivered alternately between the cycles of chemotherapy. Results: The short-term, long-term survival, median response duration and median survival time were similar between the two groups, except patients with stage IIIb who had a higher distant metastasis rate in the treatment group. The major side effects of chemotherapy and radiotherapy were hematological, gastrointestinal toxicities, pneumonitis, mediastinitis, and esophagitis, respectively. The side effects were milder, better tolerated and did not influence the regimen schedule in the treatment group, as compared with the control group. Seven patients withdrew from the control group, and in 28 patients, the scheduled chemotherapy and radiation was delayed or canceled. Conclusions: Bronchial artery infusion plus radiation is more advantageous over systemic chemotherapy plus radiation in less toxicities, better compliance, shorter treatment courses and more cost-effectiveness

    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)

    OK-432 (a lyophilized preparation of a low virulent strain, Su, of Streptococcus hemolytics (Group A) treated with penicillin G) and/or PSK (a protein-bound polysaccharide prepared from Coriolus versicolor) as an immunomodulator was administered to 209 patients of advanced lung cancer treated with radiation with combined chemotherapy. Their effects on immunological parameters and patients' survival periods were examined. Suppression of both PHA (phytohemagglutinin) skin test activities and lymphocyte blastoid transformation with PHA were reduced in the immunomodulator administered group compared with the non-administered group. Survival curves were evaluated between the patients with OK-432 and/or PSK and those without immunomodulator. It was suggested that OK-432 and/or PSK combined with radiation with combined chemotherapy was effective for the elongation of the survival period. These results indicated that the long-term administration of OK-432 and/or PSK was recommended for patients with advanced lung cancer. (author)

    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/m 2 , day 1 to 5) and cisplatin (60 mg/m 2 , 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 [de

    Here we report a case in which a locally advanced ascending colon cancer was successfully treated with anti-EGFR immunotherapy combined with chemotherapy and curative resection, and recurrent cancer was treated with the same chemotherapy. A 71-year-old man was diagnosed with ascending colon cancer in our department. No distant metastasis was observed, but curative resection was considered impossible because of extensive local cancer invasion. Because a genetic analysis revealed the presence of the wild-type KRAS gene, 6 courses of mFOLFOX6 plus cetuximab were administered. A cPR was obtained and curative resection was performed. The final diagnosis was ypT3N1M0, ypStage III a colon cancer, and chemotherapy improved the cancer stage to Grade 1b. Six courses of FOLFOX6 were then administered, followed by observation. After 2 years 6 months, a tumor of approximately 5 cm in size was noted in the right buttock using surveillance CT and was diagnosed as recurrent colon cancer. We considered further curative resection difficult and therefore 6 courses of mFOLFOX6 plus panitumumab were administered, a cPR was obtained, and right hip tumor extirpation surgery was performed. These results suggest that chemotherapy combined with anti-EGFR antibody immunotherapy is effective in treating recurrent colon cancer.

    This study was conducted to assess the effectiveness of combinations of Ayurvedic drugs in alleviating the toxicity of chemotherapy and improving the quality of life of cancer patients. The following was the research question: Can Ayurvedic drugs be used to alleviate the side effects of chemotherapy and improve the quality of life of cancer patients? Random patients with malignancies of different tissues, grades, and stages were divided into two groups according to their treatment modality. Group 1 consisted of 15 patients treated with six cycles of chemotherapy alone and who did not receive any Ayurvedic drugs (control group). Group 2 consisted of patients (divided into three arms) who received Ayurvedic drugs during chemotherapy and after chemotherapy. Nineteen patients in arm 1 received the Ayurvedic drugs Mauktikyukta Kamdudha (MKD) and Mauktikyukta Praval Panchamruta (MPP) along with a full course of chemotherapy. Fifteen patients in arm 2 received the same Ayurvedic treatment, but the treatment was started after completing the sixth cycle of chemotherapy. Eighteen patients in arm 3 received the Suvarnabhasmadi formulation (SBD) in addition to MKD and MPP after completing the sixth cycle of chemotherapy. Treatment was given for 16 weeks in all three arms. Patients from both groups were observed for a period of 6 months. The assessment criteria depended on Common Toxicity Criteria (CTC designed by NIH and NCI): haemogram; weight; physical examination including Quality of Life Questionnaire (QLQ designed by the European Organization of Research and Treatment of Cancer (EORTC)) for functional, symptom and global scores; and Karnofsky score for assessment of general well-being and activities of daily life. ECOG (Eastern Cooperation Oncology Group) score was also additionally included for assessment of symptoms. From amongst the symptomatic criteria, there was significant improvement in all the three arms compared with the control group in nausea, loss of appetite

    The aim of this study was to assess the long-term side effects of central nervous system prophylaxis (high-dose chemotherapy alone vs chemotherapy and CNS radiotherapy) according to the ALL IC-BFM 2002. Thirty-tree children aged 6.7-19.9 years have been studied. The control group consisted of 12 children newly diagnosed with acute lymphoblastic leukemia. We assessed subcortical gray matter volume using automatic MRI segmentation and cognitive performance to identify differences between two therapeutic schemes and patients prior to treatment. Patients treated with chemotherapy and CNS radiotherapy had smaller hippocampi than two other subgroups and lower IQ score than patients treated with chemotherapy alone. Both treated groups, whether with chemotherapy only or in combination with CNS radiotherapy, had significantly lower volumes of caudate nucleus and performed significantly worse on measures of verbal fluency in comparison with patients prior to treatment. There were no differences in the mean volumes of total white matter, total gray matter, thalamus, putamen, and amygdala between the studied groups. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment was observed, especially in children who received chemotherapy in combination with reduced dose CNS radiotherapy. In all children treated according to the ALL IC-BFM 2002 with high-dose chemotherapy, both decreased volume of selected subcortical structures and cognitive impairment were observed, especially in children who received chemotherapy in combination with CNS radiotherapy.

    On the background of high morbidity and mortality of hepatocellular carcinoma (HCC) and rapid development of traditional Chinese medicine (TCM), we conducted a systematic review and meta-analysis of randomized clinical trials (RCTs) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to assess the clinical effectiveness and safety of traditional insect Chinese medicine and related preparation for non-surgical HCC. RCTs were searched based on standardized searching rules in mainstream medical databases from the inception up to May 2016. Ultimately, a total of 57 articles with 4,651 patients enrolled in this meta-analysis. We found that traditional insect Chinese medicine and related preparation combined chemotherapy show significantly effectiveness and safety in objective response rate (P traditional insect Chinese medicine and related preparations could be recommended as auxiliary therapy combined chemotherapy for HCC therapy.

    Skeletal metastasis of breast carcinoma is refractory to intensive chemo-radiation therapy and therefore is assumed impossible to cure. Here, we report an advanced case of breast cancer with vertebra-Th7 metastasis that showed complete response to combined treatments with formalin-fixed autologous tumor vaccine (AFTV), palliative radiation therapy with 36 Gy, and adjuvant chemotherapy with standardized CEF (cyclophosphamide, epirubicin, and 5FU), zoledronic acid, and aromatase inhibitors following mastectomy for the breast tumor. The patient has been disease-free for more than 4 years after the mammary surgery and remains well with no evidence of metastasis or local recurrence. Thus, a combination of AFTV, palliative radiation therapy, and adjuvant chemotherapy may be an effective treatment for this devastating disease.

    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.

    To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118).

    Data suggest selective internal radiotherapy (SIRT) in third-line or subsequent therapy for metastatic colorectal cancer has clinical benefit in patients with colorectal liver metastases with liver-dominant disease after chemotherapy. The FOXFIRE, SIRFLOX, and FOXFIRE-Global randomised studies evaluated the efficacy of combining first-line chemotherapy with SIRT using yttrium-90 resin microspheres in patients with metastatic colorectal cancer with liver metastases. The studies were designed for combined analysis of overall survival. FOXFIRE, SIRFLOX, and FOXFIRE-Global were randomised, phase 3 trials done in hospitals and specialist liver centres in 14 countries worldwide (Australia, Belgium, France, Germany, Israel, Italy, New Zealand, Portugal, South Korea, Singapore, Spain, Taiwan, the UK, and the USA). Chemotherapy-naive patients with metastatic colorectal cancer (WHO performance status 0 or 1) with liver metastases not suitable for curative resection or ablation were randomly assigned (1:1) to either oxaliplatin-based chemotherapy (FOLFOX: leucovorin, fluorouracil, and oxaliplatin) or FOLFOX plus single treatment SIRT concurrent with cycle 1 or 2 of chemotherapy. In FOXFIRE, FOLFOX chemotherapy was OxMdG (oxaliplatin modified de Gramont chemotherapy; 85 mg/m 2 oxaliplatin infusion over 2 h, L-leucovorin 175 mg or D,L-leucovorin 350 mg infusion over 2 h, and 400 mg/m 2 bolus fluorouracil followed by a 2400 mg/m 2 continuous fluorouracil infusion over 46 h). In SIRFLOX and FOXFIRE-Global, FOLFOX chemotherapy was modified FOLFOX6 (85 mg/m 2 oxaliplatin infusion over 2 h, 200 mg leucovorin, and 400 mg/m 2 bolus fluorouracil followed by a 2400 mg/m 2 continuous fluorouracil infusion over 46 h). Randomisation was done by central minimisation with four factors: presence of extrahepatic metastases, tumour involvement of the liver, planned use of a biological agent, and investigational centre. Participants and investigators were not masked to treatment. The primary

    Because oral cancer treatment has advanced, resulting in a higher survival rate, it is necessary to treat the preserved oral functions such as speech, mastication, and deglutition, as well as the aesthetics. Oral cancer treatment has been performed mainly by surgical therapy and radiation therapy, however, integrated treatment including chemotherapy has recently been performed. In this study, we evaluated the effectiveness and usefulness of radiation-combined intra-arterial chemotherapy for carcinomas of the tongue, which shows a high incident rate among oral cancers and has become more common recently, to establish treatment methods for preserving the function and morphology. The subjects were 63 patients who consulted our department and underwent radiation-combined intra-arterial chemotherapy. With this therapy, the case of complete response (CR) was clinically obtained in 43 patients, and the case of partial response (PR) was obtained in 17 patients with a 68.3% CR rate and a 95.2% therapeutic effectiveness rate. Maintenance therapy was performed in 44 patients without performing surgical therapy of the primary lesion in the primary treatment. Twenty-nine among 44 patients showed a good clinical course without recurrence of primary lesion. Regarding T4, a good clinical course without recurrence was observed in 3 patients in which PR was obtained, and surgical therapy was added to the primary treatment, showing a 57.1% local control rate in T4. Considering these results, there is a high possibility that radiation-combined intra-arterial chemotherapy for carcinomas of the tongue can be implemented for avoiding surgical therapy of the primary lesion in the primary treatment, and it is useful for preserving the function and morphology with a high local control rate.

    A combination of precision (selective, intra-arterial) chemotherapy and precision radiotherapy can be used for advanced pancreatic, biliary tract, and sarcomatous malignancies. There were some remarkable responses, but also a few poor responses and even some morbidity. Accordingly, methods are developed of pre-selecting those patients whose tumors are likely to respond to such therapy, as well as methods for improving the therapeutic ratio by the rational optimization of combined therapy. Specifically, clinical tumor blood flow characteristics (monitored with nuclear medicine techniques) may provide useful criteria for such selection. The authors also evaluate qualitatively the drug distribution or exposure space with specialized color-coded computerized tomography images, which demonstrate spatially dependent enhancement of intra-arterial contrast in tumor and in adjacent normal tissues. Such clinical data can improve the quality control aspects of intra-arterial chemotherapy administration, as well as the possibility of achievement of a significant therapeutic ratio by the integration of precision chemotherapy and precision radiation therapy.

    During the period from February 1991 through October 1992, we conducted a pilot phase II trial of an 'Alternating Radiotherapy and Chemotherapy' for 15 patients with localized inoperable non-small cell lung cancer. The combined regimen, consisting of ifosfamide 1.5 g/m 2 on days 1 through 3, cisplatin 80 mg/m 2 and vindesine 3 mg/m 2 on day 1, was given repeatedly every 4 weeks. Patients were treated in a split course fashion with combination chemotherapy sandwiched between radiation therapy (total dose 60 Gy). Of 15 evaluable patients, complete remission, partial remission and no change were obtained in 1, 13 and 1 patients, respectively, with an overall response rate of 93.3%. The median survival for all patients was 62 weeks. Hematologic toxicity was severe and was judged to be dose limiting. It was, however, clinically manageable with colony stimulating factor. These results indicate that this alternating radiotherapy and chemotherapy is feasible for localized non-small cell lung cancer and warrants further clinical trials. (author)

    Purpose: Prospectively designed randomized clinical study was undertaken to assess the efficacy of simultaneous application of irradiation, Mitomycin C, and Bleomycin in treatment of patients with inoperable head and neck carcinoma. Methods and Materials: Between March 1991 and October 1993, 49 patients with inoperable head and neck carcinoma were randomly assigned to receive either radiation therapy alone (group A) or radiotherapy combined with simultaneous application of Mitomycin C and Bleomycin (group B). Patients in both groups were irradiated five times weekly with 2 Gy to the total dose of 66-70 Gy. Chemotherapy regimen included intramuscular application of Bleomycin 5 units twice a week, with the planned dose being 70 units and Mitomycin C 15 mg/m 2 applied intravenously after delivery of 9-10 Gy of irradiation. The application of Mitomycin C was planned to be repeated on last day of radiotherapy in the dose of 10 mg/m 2 . In attempt to enhance the effect of chemotherapeutic drugs, patients in group B received also Nicotinamide, Chlorpromazine, and Dicoumarol. Results: The difference in complete response rate between both treatment groups (24% in group A and 63% in group B) was statistically significant (p = 0.015). The difference in response rate was much more pronounced in patients with oropharyngeal carcinoma only (18% in group A compared to 81% in group B; p = 0.0003), while for all other subgroups added together, there was observed no benefit of multidrug therapy. Median follow-up was 18 months. Disease-free survival of patients in group A (9%) was significantly lower then in group B (48%) (p 0.001). The difference between both treatment groups was even greater in patients with oropharyngeal carcinoma only: disease-free survival of these patients in group B was 66%, while in group A, all recurred (p = 0.00001). Conclusion: From results of our prospective randomized study it seems that the group of patients that received multidrug treatment with

    The aim was to evaluate the feasibility and the effectiveness of neoadjuvant systemic chemotherapy using FLOT - protocol followed by cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC) followed by systemic chemotherapyand in patients with peritoneal carciriomatosis (PC) from gastric cancer. Twenty six (median age 53 years, range 39 - 71) were scheduled for three cycles of neoadjuvant systemic chemotherapy using bi-weekly FLOT - protocol followed by CRS + HIPEC. Thereafter 3 additional cycles of FLOT were given. During HIPEC in Colliseum technique Oxaliplatin was given in a dosage of 200 mg/m2 and Docetaxel in a dosage of 80 mg/m2. All patients underwent cytoreductive surgery plus HIPEC. Peritoneal Cancer index was > 15 in 3 cases only. Complete resection could be carried out in all cases (CC-O 18, CC-18). Postoperative complication rate was 23% with no mortality within 30 days. Anastomotic leakage rate was 3.2%. Overall survival was 19.0 months with a 2-year survival rate 38%. Regression analysis demonstrated a Peritoneal Cancer Index PCI > 12 as negative factor for survival. Neoadju- vant chemotherapy using FLOT - protocol followed by CRS + HIPEC seems to be associated with prolonged OS in patients with peritoneal carcinomatosis from gastric cancer. This treatment is not recommended for patients with extensive peritoneal involvement and PCI > 12.

    Cases of metastatic anal carcinoma managed with a combination of systemic chemotherapy and local therapies to both solitary sites of metastases and the primary site have been reported in the literature. We present a case of a 55-year-old male with metastatic anal squamous cell carcinoma to the liver treated with induction chemotherapy with cisplatin (CDDP) and 5-fluorouracil (5FU) followed by liver resection and radiation to the anal primary with concurrent 5FU and mitomycin. This approach resulted in control of disease without evidence of recurrence, and no increased toxicities now 19 months from initial diagnosis to time of reporting. This novel approach resulted in a good treatment response as documented by imaging and symptom improvement and a long disease free interval.

    Prolongation of survival of patients with small cell carcinoma of the lung with current effective systemic therapy has been accompanied by a marked increase in the frequency of relapse in the central nervous system (CNS). Prophylactic cranial irradiation (PCI) was shown to reduce the frequency of brain metastasis, but there was no increased short-term survival. Therefore, the necessity for PCI early in the course of treatment has been questioned, especially for patients with extensive disease. From January 1974 through March 1982, 205 patients with small cell carcinoma of the lung were treated at the Medical College of Wisconsin Affiliated Hospitals. None had clinical, radioisotopic, or computed tomographic evidence of brain metastasis. Eighty-two patients received radiotherapy and chemotherapy, but no PCI; 123 patients received combination chemotherapy and radiation therapy with PCI. The cumulative probability of brain metastasis without PCI was 36% at 12 months and 47% at 24 months; the probabilities were 6 and 10%, respectively with PCI. The 24-month probability of brain metastasis in patients with limited disease and no PCI was 45%; for those with extensive disease, it was 47%. No patient presented with extracranial central nervous system (ECNS) metastasis and no one without PCI developed it. Twelve patients who received PCI developed ECNS metastasis; the cumulative probabilities rose to 14% at 12 months and 22% at 24 months. The increased frequency of ECNS involvement has led to a phase I trial of PCI followed by six cycles of combination chemotherapy, without maintenance chemotherapy, followed by irradiation of the chest and spinal cord for patients with complete response

    Full Text Available Combination antiemetic regimens targeting multiple molecular pathways associated with emesis have become the standard of care for prevention of chemotherapy-induced nausea and vomiting (CINV related to highly and moderately emetogenic chemotherapies. Antiemetic consensus guidelines from several professional societies are widely available and updated regularly as new data emerges. Unfortunately, despite substantial research supporting the notion that guideline conformity improves CINV control, adherence to antiemetic guidelines is unsatisfactory. While studies are needed to identify specific barriers to guideline use and explore measures to enhance adherence, a novel approach has been taken to improve clinician adherence and patient compliance, with the development of a new combination antiemetic. NEPA is an oral fixed combination of a new highly selective NK1 receptor antagonist (RA, netupitant, and the pharmacologically and clinically distinct 5-HT3 RA, palonosetron. This convenient antiemetic combination offers guideline-consistent prophylaxis by targeting two critical pathways associated with CINV in a single oral dose administered only once per cycle. This paper will review and discuss the NEPA data in the context of how this first combination antiemetic may overcome some of the barriers interfering with adherence to antiemetic guidelines, enhance patient compliance, and offer a possible advance in the prevention of CINV for patients.

    This study was conducted to compare the efficacy of a combination of icotinib and chemotherapy with icotinib or chemotherapy alone in untreated non-small cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR)-sensitive mutations and to analyze the curative effect of different treatments on different genetic mutations (EGFR 19 exon deletion and L858R mutation) in a real-life setting. One hundred ninety-one patients were studied in this retrospective analysis from January 2013 to December 2015. The baseline characteristics, curative effects and adverse events of patients were analyzed. The primary endpoint was progression free survival (PFS). Longer PFS and overall survival (OS), and better objective response rate (ORR) were observed in the combination group compared to icotinib or chemotherapy along. For patients with an EGFR 19 exon deletion, the PFS, OS, and ORR in the combination group were superior to those in the icotinib or chemotherapy group. For the patients with the EGFR L858R mutation, better PFS and ORR were observed in the combination group, but OS was not obviously prolonged. Grade 3 or 4 adverse events were most commonly reported with combination therapy or chemotherapy alone. No possible drug-related interstitial lung disease or of drug related deaths occurred. The combination of icotinib and chemotherapy in patients with untreated NSCLC harboring sensitive EGFR mutations resulted in improved PFS and OS, especially in those who harbored the EGFR exon 19 deletion.

    Amuvatinib (MP-470) is a multi-targeted kinase inhibitor with potent activity against c-Kit, synergistic with DNA-damaging agents. We evaluated amuvatinib in combination with platinum-etoposide (EP) chemotherapy by objective response rate, survival, and tolerability in platinum-refractory small cell lung cancer (SCLC) patients. This study used a Simon 2-stage design requiring ≥3 centrally confirmed responses in the first 21 subjects. Subjects received EP with 300 mg amuvatinib orally three times daily in cycles of 21 days. A three-day amuvatinib run-in period before EP occurred in Cycle 1. Subjects received the same EP chemotherapy regimen given prior to progression/relapse. Among 23 subjects treated, we observed four PRs (17.4%) per RECIST 1.1, only two of which were centrally confirmed (8.7%, response duration 119, 151 days). Three subjects (13%) had confirmed stable disease. c-Kit H-score was ≥100 in two subjects whose respective durations of disease control were 151 and 256 days. The addition of amuvatinib to EP chemotherapy in unselected, platinum-refractory SCLC did not meet the primary endpoint of ≥3 confirmed responses in stage 1. However, high c-Kit expression in two subjects with durable disease control suggests the potential for further study of amuvatinib in SCLC patients with high c-Kit expression.

    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. © 2014 John Wiley & Sons Ltd.

    This prospective randomized study is to evaluate the locoregional failure and its impact on survival by comparing involved field radiotherapy (IFRT) with elective nodal irradiation (ENI) in combination with concurrent chemotherapy for locally advanced non-small cell lung cancer. It appears that higher dose could be delivered in IFRT arm than that in ENI arm, and IFRT did not increase the risk of initially uninvolved or isolated nodal failures. Both a tendency of improved locoregional progression-free survival and a significant increased overall survival rate are in favor of IFRT arm in this study. PMID:23762840

    Cancer cachexia is characterized by muscle wasting caused partly by systemic inflammation. We previously demonstrated an immune-modulating diet (IMD), an enteral diet enriched with immunonutrition and whey-hydrolyzed peptides, to have antiinflammatory effects in some experimental models. Here, we investigated whether the IMD in combination with chemotherapy could prevent cancer cachexia in colon 26 tumor-bearing mice. Forty tumor-bearing mice were randomized into 5 groups: tumor-bearing control (TB), low dose 5-fluorouracil (5-FU) and standard diet (LF/ST), low dose 5-FU and IMD (LF/IMD), high dose 5-FU and standard diet (HF/ST) and high dose 5-FU and IMD (HF/IMD). The ST and IMD mice received a standard diet or the IMD ad libitum for 21 days. Muscle mass in the IMD mice was significantly higher than that in the ST mice. The LF/IMD in addition to the HF/ST and HF/IMD mice preserved their body and carcass weights. Plasma prostaglandin E2 levels were significantly lower in the IMD mice than in the ST mice. A combined effect was also observed in plasma interleukin-6, glucose, and vascular endothelial growth factor levels. Tumor weight was not affected by different diets. In conclusion, the IMD in combination with chemotherapy prevented cancer cachexia without suppressing chemotherapeutic efficacy.

    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.

    We evaluated the efficacy and safety of M-VAC chemotherapy combined with mild hyperthermia, a new therapeutic strategy for advanced metastatic transitional cell carcinoma of the urothelium. The subjects were 12 patients diagnosed with advanced metastatic transitional cell carcinoma of the urothelium. For mild hyperthermia, the patients' oral temperature was elevated to about 38 degrees C by heating for 20 min and retaining the heat for 20 min with a far-infrared heater. The antitumor effect was evaluated according to the RECIST, while adverse drug reactions were assessed based on the NCI-CTC. The antitumor effect was rated as partial remission (PR) in 10 of the 12 patients and stable disease in 2 patients, with an efficacy rate of 83% (10/12). All 10 patients who had achieved PR received three courses of treatment. Of the 12 patients, 5 died during the observation period, with survival for 9-23 months (mean: 15.6 months). Adverse drug reactions included myelosuppression in all patients (Grade 3 in 4 patients, Grade 4 in 8), and gastrointestinal toxicity, such as nausea or vomiting, which was mild (Grade 0 in 2 patients, Grade 1 in 8, Grade 2 in 1, Grade 3 in 1). The results of the present study suggest that M-VAC chemotherapy combined with mild hyperthermia, which potentiates the anticancer effect and reduces adverse drug reactions such as gastrointestinal symptoms, is a useful and safe method for the treatment of advanced transitional cell carcinoma of the urothelium.

    43 patients with stage III NSCLC (non-small cell lung cancer) entered a phase II study aimed at evaluating the toxicity and the activity of a combined modality programme including an accelerated split-course schedule (type B) of thoracic radiation therapy and a combination chemotherapy with vinorelbine and carboplatin. An objective response was achieved in 18/42 evaluable patients (5 complete and 13 partial responses), for an overall response rate of 43% (95% confidence interval, 28-58%). Four complete responses had a duration which exceeded 16 months. Treatment was well tolerated; grade III myelotoxicity occurred in only 14% of patients and treatment was delayed in only 2 cases because of grade 3 oesophagitis. Both tolerability and efficacy data suggest that this regimen holds promise for the treatment of patients with stage III NSCLC. (author)

    Due to the high incidence of local recurrence and liver metastasis, long-term outcomes for patients after resection of pancreatic cancer are extremely poor. For improving the survival of the patients, a combination of preoperative chemoradiation, surgery, and postoperative liver-perfusion chemotherapy (LPC) were performed. Postoperative histopathologic study revealed a marked degenerative change in cancer tissue, showing negative surgical margins (R0) in 98% of patients and negative nodal involvement in 85% of patients. The 5-year survival rate after pancreatectomy was 56%, with low incidences of both local recurrence (11%) and liver metastasis (9%). This combination therapy were able to effectively reduce the incidence of both local and liver recurrence and improved long-term outcomes for patients with T3-4 cancers of the pancreas. (author)

Patients and methods: One hundred ninety-one patients were studied in this retrospective analysis from January 2013 to December 2015. The baseline characteristics, curative effects and adverse events of patients were analyzed. The primary endpoint was progression free survival (PFS. Results: Longer PFS and overall survival (OS, and better objective response rate (ORR were observed in the combination group compared to icotinib or chemotherapy along. For patients with an EGFR 19 exon deletion, the PFS, OS, and ORR in the combination group were superior to those in the icotinib or chemotherapy group. For the patients with the EGFR L858R mutation, better PFS and ORR were observed in the combination group, but OS was not obviously prolonged. Grade 3 or 4 adverse events were most commonly reported with combination therapy or chemotherapy alone. No possible drug-related interstitial lung disease or of drug related deaths occurred. Conclusion: The combination of icotinib and chemotherapy in patients with untreated NSCLC harboring sensitive EGFR mutations resulted in improved PFS and OS,especially in those who harbored the EGFR exon 19 deletion.

    We report a case of advanced pancreatic cancer with liver and lung metastases that was well controlled over one year by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion in an outpatient setting. The patient was a 74-year-old woman. Chief complaints were back pain and anorexia. She was diagnosed with pancreas cancer with liver and lung metastases at the time of first visit. We started systemic chemotherapy with gemcitabine 1 g/body and 5-FU 1 g/body alternately every other week on an outpatient basis. At 1.5 months (M) after initiation of chemotherapy, we started radiation therapy to the main tumor at a total dose of 40 Gy. After radiation, chemotherapy was resumed. As a result, the size of the main tumor decreased but metastatic liver tumors got larger. Then we changed to combination therapy with systemic chemotherapy (gemcitabine and 5-FU) and hepatic arterial infusion (5-FU weekly). Liver metastases almost disappeared after 7.5 M. Despite all these treatments, however, the number of metastatic lung tumors increased. The patient was hospitalized for 15 M and died after 17 M. We focused on and succeeded in the prolongation of lifetime and maintenance of QOL by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion therapy.

    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.

    DNA hypermethylation and histone deacetylation are pathways of leukemia resistance. We investigated the tolerability and efficacy of decitabine and vorinostat plus chemotherapy in relapse/refractory acute lymphoblastic leukemia (ALL). Decitabine (15 mg/m(2) iv) and vorinostat (230 mg/m(2) PO div BID) were given days 1-4 followed by vincristine, prednisone, PEG-asparaginase, and doxorubicin. Genome wide methylation profiles were performed in 8 matched patient bone marrow (BM) samples taken at day 0 and day 5 (postdecitabine). The median age was 16 (range, 3-54) years. All patients had a prior BM relapse, with five relapsing after allogeneic transplant. The most common nonhematological toxicities possibly related to decitabine or vorinostat were infection with neutropenia (grade 3; n = 4) and fever/neutropenia (grade 3, n = 4; grade 4, n = 1). Of the 13 eligible patients, four achieved complete remission without platelet recovery (CRp), two partial response (PR), one stable disease (SD), one progressive disease (PD), two deaths on study and three patients who did not have end of therapy disease evaluations for an overall response rate of 46.2% (CRp + PR). Following decitabine, significant genome-wide hypo-methylation was observed. Comparison of clinical responders with nonresponders identified methylation profiles of clinical and biological relevance. Decitabine and vorinostat followed by re-Induction chemotherapy was tolerable and demonstrated clinical benefit in relapsed patients with ALL. Methylation differences were identified between responders and nonresponders indicating interpatient variation, which could impact clinical outcome.

    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

    The combination of a fluoropyrimidine [5-fluorouracil (5-FU), capecitabine, or S-1] with a platinum analog (cisplatin or oxaliplatin) is the most widely accepted first-line chemotherapy regimen for metastatic or recurrent advanced gastric cancer (AGC), based on the results of clinical trials. However, there is little evidence to guide chemotherapy for elderly patients with AGC because of under-representation of this age group in clinical trials. Thus, the aim of this study is to determine the optimal chemotherapy regimen for elderly patients with AGC by comparing the efficacies and safeties of combination therapy versus monotherapy as first-line chemotherapy. This study is a randomized, controlled, multicenter, phase III trial. A total of 246 elderly patients (≥70 years old) with metastatic or recurrent AGC who have not received previous palliative chemotherapy will be randomly allocated to a combination therapy group or a monotherapy group. Patients randomized to the combination therapy group will receive fluoropyrimidine plus platinum combination chemotherapy (capecitabine/cisplatin, S-1/cisplatin, capecitabine/oxaliplatin, or 5-FU/oxaliplatin), and those randomized to the monotherapy group will receive fluoropyrimidine monotherapy (capecitabine, S-1, or 5-FU). The primary outcome is the overall survival of patients in each treatment group. The secondary outcomes include progression-free survival, response rate, quality of life, and safety. We are conducting this pragmatic trial to determine whether elderly patients with AGC will obtain the same benefit from chemotherapy as younger patients. We expect that this study will help guide decision-making for the optimal treatment of elderly patients with AGC.

    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/m 2 at D1 and D29) and 5-fluorouracil (800 mg/m 2 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

    We have investigated the efficacy of standard conditioning regimens for bone marrow transplantation in depleting functional T lymphocytes in vivo and have compared it with the efficacy of the monoclonal antibody Campath-1G. Using limiting dilution techniques the frequencies of proliferating T cell precursors (PTL), cytotoxic T cell precursors (CTL-p), helper T cell precursors (HTL-p), and mature helper T cells (HTL) were determined before and after treatment. Both total body irradiation and combination chemotherapy with busulfan/cyclophosphamide were highly efficient at depleting PTL, CTL-p, and HTL-p (0-4 days) but spared HTL to a variable extent (0-99.5%). In the majority of patients treated with Campath-1G a similar degree of PTL, CTL-p, and HTL-p depletion was achieved, and, in addition, HTL were effectively removed (greater than 95.5%). These results suggest that Campath-1G could be successfully employed in depleting radio- and chemotherapy-resistant host T lymphocytes prior to T-depleted bone marrow transplantation

    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. 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/m 2 of pemetrexed intravenously every 21 days and erlotinib (100 mg at Level 1 and 150 mg at Level 2) orally on days 2–16. 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. Combination chemotherapy of intermittent erlotinib with pemetrexed was well-tolerated, with promising efficacy against pretreated advanced nonsquamous NSCLC

    A Novel poly [2-hydroxyethyl methacrylate-Lactide-dimethylaminoethyl methacrylate quaternary ammonium alkyl halide] [P(HEMA-LA-MADQUAT)] copolymer was synthesized through combination of ring opening polymerization (ROP) and 'free' radical initiated polymerization methods. This newly developed copolymer was fully characterized by FT-IR, 1 HNMR and 13 CNMR spectroscopy. Micellization of the copolymer was performed by dialysis membrane method and obtained micelles were characterized by FESEM, dynamic light scattering (DLS), zeta potential (ξ), and critical micelle concentration (CMC) measurements. This copolymer was developed with the aim of co-delivering two different anticancer drugs: methotrexate (MTX) and chrysin. In vitro cytotoxicity effect of MTX@Chrysin-loaded P(HEMA-LA-MADQUAT) was also studied through assessing the survival rate of breast cancer cell line (MCF-7) and DAPI staining assays. Cationic micelle (and surface charge of + 7.6) with spherical morphology and an average diameter of 55 nm and CMC of 0.023 gL -1 was successfully obtained. Micelles showed the drug loaded capacity around 87.6 and 86.5% for MTX and Chrysin, respectively. The cytotoxicity assay of a drug-free nanocarrier on MCF-7 cell lines indicated that this developed micelles were suitable nanocarriers for anticancer drugs. Furthermore, the MTX@Chrysin-loaded micelle had more efficient anticancer performance than free dual anticancer drugs (MTX @ chrysin), confirmed by MTT assay and DAPI stainingmethods. Therefore, we envision that this recently developed novel micelle can enhance the efficacy of chemotherapeutic agents, MTX and Chrysin, combination chemotherapy and has the potential to be used as an anticancer drug delivery system for in vivo studies. Therefore, this recently developed novel micelle can enhance the efficacy of chemotherapeutic agents, MTX and Chrysin, combination chemotherapy and has the potential to be used as an anticancer drug delivery system for in vivo studies.

    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 1 st and 5 th 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.

    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

    Between 1975 and 1979, 209 cases of primary lung cancer admitted to the department of radiology were treated with radiation with combined chemotherapy. OK-432 and/or PSK as an immunomodulator was administered to 130 of these cases, and survival curves were evaluated between the patients with OK-432 and/or PSK and those without immunomodulator. In 61 cases (squamous cell carcinoma and adenocarcinoma) in stage III (UICC, 1978), fifty percent survival period was found to be 12.5 months for 16 cases with OK-432, 13.5 months for 9 cases with OK-432 and PSK, 9.0 months for 18 cases with PSK, and 8.0 months for 18 cases without immunotherapy, respectively.

    To evaluate the clinical efficacy of zoledronic acid combined with chemotherapy in the management of skeletal metastasis of non-small cell lung cancer (NSCLC) and investigate the value in urine amino-terminal telopeptide of type I collagen (uNTX) and serum bone specific alkaline phosphatase (sBALP) in monitoring skeletal metastasis of NSCLC. From February, 2007 to January, 2009, 32 NSCLC patients with bone metastases received treatment with zoledronic acid at the dose of 4 mg given every 3 weeks and platinum-based chemotherapy (each cycle lasting for 3 weeks). Before and during the treatments, uNTX and sBALP were measured in these patients using ELISA and precipitation with wheat germ lectin, respectively. The patients were followed up for skeletal-related events (SREs) and status of survival. A significant decrease occurred in the pain scores and analgesic use in the patients after the therapy. SREs were not observed during the treatment. Serum creatinine and calcium levels underwent no significant variation during the treatment. Eleven patients reported 14 possible zoledronic acid-related adverse events. The concentration of uNTX and sBALP in patients with bone metastases was above the upper limit of the normal range. A positive correlation was observed between the levels of the markers and the extent of bone metastases. At the third month, uNTX and sBALP were significantly lowered, but radionuclide whole-body bone imaging showed no obvious changes. Of the 32 patients, 24 had elevated uNTX values, which became normal after the treatment in 15 patients and remained elevated in the other 9 patients. SREs occurred in these two subgroups at the rates of 53% and 89% (P=0.039), respectively. Twenty-six patients had elevated sBALP level, and 16 of them exhibited normal sBALP level after the treatment. The incidences of SREs in the patients with elevated and normal sBALP level were 50% and 90% (P=0.038), respectively. The levels of uNTX/Cr and sBALP were not correlated

    Docetaxel and doxorubicin have produced a high degree of activity in previously untreated/treated patients with metastatic breast cancer (MBC). The efficacy of Taxotere (T) single agent as 2nd line chemotherapy is well established in large randomized phase III studies. The objective of this study is to confirm the efficacy and safety of a combination of Taxotere with doxorubicin as 1st line chemotherapy in Indonesian MBC patients. TREATMENT AND METHOD: Eighteen patients age < or = 70 years with advanced or metastatic breast cancer (MBC) with no prior taxane chemotherapy or prior cumulative doxorubicin (D) of no more than 250 mg/m2 and no heart disease were enrolled in this phase II study of D (50 mg/m2) IV bolus followed one hour later by Taxotere (T) 60 mg/m2 IV infusion over 1 hour every 3 weeks for 6 cycles treatments. A 3-day oral corticosteroid premedication was administered starting one day before the infusion of each cycle. Left ventricular ejection fraction (LVEF) was evaluated at baseline and after cycle 6. 18 patients (pts) have been treated with 108 cycles administered. Median age was 46 years (31-58), WHO PS 0 = 50%, 1 = 50% and number of organs involved were: 2 (72%), 3 (22%) and 4 (6%). After 3 cycles, partial (PR) and no change (NC) responses occurred in 15 pts (83.3%) and 3 pts (16.7%). The best overall response after 6 cycles, including complete (CR) and partial (PR) responses, occurred in 13 pts (72.2%) including 3 CRs and 10 PRs. Two patients with extensive liver metastases at the baseline had a complete disappearance after 6 cycles. No patients developed congestive heart failure (CHF). Grade 3/4 hematological toxicities included leukopenia in 18 pts (100%), febrile neutropenia in 6 pts (33%), leukopenia with infection in 2 pts (11%), leukopenia with fever in 1 pt (5.5%), and anemia in 6 pts (33.3%). Nonhematological toxicities grade 3/4 included alopecia (61%), asthenia (4.6%), nausea/vomiting (2.7%), pain (2.7%), stomatitis (2.7%), and

    To retrospectively determine the safety and efficacy of combined chemotherapy with carmustine (BCNU) wafer, bevacizumab, and temozolomide plus radiotherapy in patients with newly diagnosed glioblastoma (GBM). A total of 54 consecutive newly diagnosed GBMs were resected at our institution between 2010 and 2016. Twenty-nine patients underwent BCNU wafer implantation into the resection cavity followed by standard radiochemotherapy with temozolomide (TMZ, Stupp regimen) plus additional bevacizumab treatment between 2013 and 2016. Twenty-five patients who underwent resection without BCNU implantation between 2010 and 2012 were enrolled as a control group; these patients were treated with the Stupp regimen and did not receive bevacizumab. This retrospective study included evaluation of progression-free survival and overall survival, plus comparisons between the combined therapy group and the control group. There were no significant differences in age, sex, Karnofsky Performance Status on admission, isocitrate dehydrogenase 1/2 mutation ratio, or resection rate between the combined and standard therapy groups. The median overall survival in the combined therapy group and control group was 24.2 months and 15.30, respectively (P = 0.027). The median progression-free survival was 16.8 months and 7.30 months, respectively (P = 0.009). Overall, the incidence of adverse events leading to discontinuation of the study drug was similar between the treatment groups, except for infection, which was more common in the combined treatment group and required repeat surgery. The combined therapy showed higher efficacy compared with standard therapy in patients with GBM. Therefore, combined therapy seems to be effective with an acceptable toxicity profile.

    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

    Ovarian cancer represents the most lethal gynecological cancer. Although cytoreductive chemotherapy and surgery lead to complete macroscopic tumor removal, most of the patients in advanced stages suffer from recurrent disease and subsequently die. This may be explained by the activity of cancer stem cells (CSC), which are a subpopulation of cells with an elevated chemoresistance and an increased capacity for self-renewal and metastatic spread. Specifically targeting these cells by adoptive immunotherapy represents a promising strategy to reduce the risk for recurrent disease. This study selected the widely accepted CSC marker CD133 as a target for a chimeric antigen receptor (CAR)-based immunotherapeutic approach to treat ovarian cancer. A lentiviral vector was generated encoding a third-generation anti-CD133-CAR, and clinically used NK92 cells were transduced. These engineered natural killer (NK) cells showed specific killing against CD133-positive ovarian cancer cell lines and primary ovarian cancer cells cultured from sequential ascites harvests. Additionally, specific activation of these engineered NK cells was demonstrated via interferon-gamma secretion assays. To improve clinical efficacy of ovarian cancer treatment, the effect of the chemotherapeutic agent cisplatin was evaluated together with CAR-transduced NK cell treatment. It was demonstrated that NK cells remain cytotoxic and active under cisplatin treatment and, importantly, that sequential treatment with cisplatin followed by CAR-NK cells led to the strongest killing effect. The specific eradication of ovarian CSCs by anti-CD133-CAR expressing NK92 cells represents a promising strategy and, when confirmed in vivo, shall be the basis of future clinical studies with the aim to prevent recurrent disease.

    Chemotherapy alone, either as a single drug or a combination of drugs with or without external radiation (ER) is useful for treatment of locally advanced disease and non iodine concentrating metastasis in differentiated thyroid cancers (DTC). The reported response is not encouraging, but the absence of better alternatives leave no choice for the treatment of such cases. However, for treatment of anaplastic thyroid cancers (ANC), chemotherapy (CT) in combination with ER results in local control. In medullary thyroid cancers (MTC), the results obtained with multimodal treatment are encouraging

    Cancer cachexia is characterised by the loss of body mass and directly compromises immune response and the quality of life of cancer patients. In the present study, we set out to investigate the role of Chinese herbs as anticancer medicines and/or chemotherapeutic adjuvants to increase therapeutic efficacy and/or ameliorate given side-effects in animal model. Twelve kinds of herbs were chosen from the ingredients of major Chinese herbal medicines, and their effects on the antioxidant activity were investigated. To obtain the anticancer effects of 5-fluorouracil (5-FU) when consumed with minimal side-effects, we investigated the combination effect of Scutellaria baicalensis and Qing-Shu-Yi-Qi-Tang that may enhance the anticancer activity of 5-FU on subcutaneous tumour growth in C57BL/6 mice challenged with Lewis lung carcinoma cells. Qing-Shu-Yi-Qi-Tang, a multiple-component herbal extract, was shown to have high anti-oxidation activity, while S. baicalensis (Chinese skullcap) was demonstrated to have high tumour-growth inhibition activity. Thus, S. baicalensis and Qing-Shu-Yi-Qi-Tang were evaluated for their combinaton effects on the cancer-induced cachectic murine upon receiving 5-FU chemotherapy. As a result, tumour masses and losses of carcass and/or gastrocnemius muscle were found to be significantly decreased. This combination otherwise increased both Th1/Th2 ratio and NK cytotoxicity. In the mice receiving with or without 5-FU, the serum levels of monocyte chemoattractant protein-1 (MCP-1) increased by all means but otherwise decreased when the herbal combination was administrated. Additionally, the expressions of nuclear factor-kappa B (NF-κB) and muscle RING finger protein-1 (MuRF-1) decreased in the gastrocnemius muscle when the herbal combination was applied. Our results revealed that the combination of S. baicalensis and Qing-Shu-Yi-Qi-Tang is able to ameliorate cachectic symptoms and positively stimulate anti-tumour immunity while undergoing

    Between 1975 and 1979, 209 cases of primary lung cancer admitted the department of radiology were treated with radiation combined with chemotherapy. The clinical effect of concomitant use of non-specific immunopotentiator OK-432 and PSK was studied about stage 3, and stage 4. Survival curves were evaluated between the patients with OK-432 and/or PSK and those without immunotherapy. In 91 cases in stage 3, fifty percent survival period was found to be 12.2 months for 27 cases with OK-432, 14.4 months for 12 cases with combined use of OK-432 and PSK, 9.0 months for 24 cases with PSK, and 7.5 months for 28 cases without immunotherapy, respectively. Noticeable prolongation of fifty percent survival period was observed in the cases with combined use of OK-432 and PSK, OK-432, and PSK, inorder, as compared with those without immunotherapy.

    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

    Histone deacetylases (HDACs) have been identified as therapeutic targets due to their regulatory function in chromatin structure and organization. Here, we analyzed the therapeutic effect of LBH589, a class I-II HDAC inhibitor, in acute lymphoblastic leukemia (ALL). In vitro, LBH589 induced dose-dependent antiproliferative and apoptotic effects, which were associated with increased H3 and H4 histone acetylation. Intravenous administration of LBH589 in immunodeficient BALB/c-RAG2(-/-)γc(-/-) mice in which human-derived T and B-ALL cell lines were injected induced a significant reduction in tumor growth. Using primary ALL cells, a xenograft model of human leukemia in BALB/c-RAG2(-/-)γc(-/-) mice was established, allowing continuous passages of transplanted cells to several mouse generations. Treatment of mice engrafted with T or B-ALL cells with LBH589 induced an in vivo increase in the acetylation of H3 and H4, which was accompanied with prolonged survival of LBH589-treated mice in comparison with those receiving vincristine and dexamethasone. Notably, the therapeutic efficacy of LBH589 was significantly enhanced in combination with vincristine and dexamethasone. Our results show the therapeutic activity of LBH589 in combination with standard chemotherapy in pre-clinical models of ALL and suggest that this combination may be of clinical value in the treatment of patients with ALL.

    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.) [de

    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

    The distinct and complementary biochemical mechanisms of folic acid analog methotrexate (MTX) and cytidine analog gemcitabine (GEM) make their synergistic combination effective. Unfortunately, such a combination faces severe pharmacokinetic problems and several transportation barriers. To overcome these problems, a new strategy of amphiphilic small molecule prodrug (ASMP) is developed to improve their synergistic combination effect. The ASMP was prepared by the amidation of the hydrophilic GEM with the hydrophobic MTX at a fixed ratio. Owing to its inherent amphiphilicity, the MTX-GEM ASMP self-assembled into stable nanoparticles (ASMP-NPs) with high drug loading capacity (100%), in which the MTX and GEM could self-deliver without any carriers and release synchronously in cancer cells. In vitro studies showed that the MTX-GEM ASMP-NPs could greatly improve the synergistic combination effects by the reason of arresting more S phase of the cell cycle and reducing levels of deoxythymidine triphosphate (dTTP), deoxyadenosine triphosphate (dATP), and deoxycytidine triphosphate (dCTP). The stronger synergistic effects caused the higher cell cytotoxicity and apoptotic ratio, and circumvented the multidrug resistance (MDR) of tumor cells. Additionally, MTX-GEM ASMP-NPs could achieve the same anticancer effect with the greatly reduced dosage compared with the free drugs according to the dose-reduction index (DRI) values of MTX and GEM in MTX-GEM ASMP-NPs, which may be beneficial for reducing the side effects.

    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.

    Activatable photosensitizers (PSs) and chemo-prodrugs are highly desirable for anti-cancer therapy to reduce systemic toxicity. However, it is difficult to integrate both together into a molecular probe for combination therapy due to the complexity of introducing PS, singlet oxygen quencher, chemo-drug, chemo-drug inhibitor and active linker at the same time. To realize activatable PS and chemo-prodrug combination therapy, we develop a smart therapeutic platform in which the chemo-prodrug serves as the singlet oxygen quencher for the PS. Specifically, the photosensitizing activity and fluorescence of the PS (TPEPY-SH) are blocked by the chemo-prodrug (Mitomycin C, MMC) in the probe. Meanwhile, the cytotoxicity of MMC is also inhibited by the electron-withdrawing acyl at the nitrogen position next to the linker. Upon glutathione activation, TPEPY-S-MMC can simultaneously release active PS and MMC for combination therapy. The restored fluorescence of TPEPY-SH is also used to report the activation for both PS and MMC as well as to guide the photodynamic therapy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The combination of paclitaxel + ramucirumab is a standard second-line treatment in patients with advanced gastric cancer. This therapy has been associated with increased median overall survival and progression-free survival compared with those with paclitaxel monotherapy. We evaluated the cost-effectiveness of paclitaxel + ramucirumab combination therapy in patients with advanced gastric cancer, from the perspective of health care payers in Japan. We constructed a Markov model to compare, over a time horizon of 3 years, the costs and effectiveness of the combination of paclitaxel + ramucirumab and paclitaxel alone as second-line therapies for advanced gastric cancer in Japan. Health outcomes were measured in life-years (LYs) and quality-adjusted (QA) LYs gained. Costs were calculated using year-2016 Japanese yen (¥1 = US $17.79) according to the social insurance reimbursement schedule and drug tariff of the fee-for-service system in Japan. Model robustness was addressed through 1-way and probabilistic sensitivity analyses. The costs and QALYs were discounted at a rate of 2% per year. The willingness-to-pay threshold was set at the World Health Organization's criterion of ¥12 million, because no consensus exists regarding the threshold for acceptable cost per QALY ratios in Japan's health policy. Paclitaxel + ramucirumab combination therapy was estimated to provide an additional 0.09 QALYs (0.10 LYs) at a cost of ¥3,870,077, resulting in an incremental cost-effectiveness ratio of ¥43,010,248/QALY. The incremental cost-effectiveness ratio for the combination therapy was >¥12 million/QALY in all of the 1-way and probabilistic sensitivity analyses. Adding ramucirumab to a regimen of paclitaxel in the second-line treatment of advanced gastric cancer is expected to provide a minimal incremental benefit at a high incremental cost per QALY. Based on our findings, adjustments in the price of ramucirumab, as well as improves in other clinical parameters such as survival

    We have designed a combined treatment strategy of bifractionated split course radiotherapy (RT) and concomitant chemotherapy (CT) to try to improve the results of RT in inoperable cervical carcinoma. After evaluation, patients were submitted to further radical surgery or additional RT-CT depending on the treatment results. Between January 1992, 25 patients with non metastatic inoperable disease entered in the protocol. The stage of the disease was: T{sub 3}N{sub 0}4 patients, T{sub 3} with hydronephrosis seven patients, T{sub 3}N{sub 1} 12 patients, and T{sub 4}N{sub 0} two patients. Nineteen patients received two courses of CT with fluorouracil (F), cisplatin (P) with or without etoposide. Pelvic RT was given twice daily (two fractions of 3 Gy) on days 1, 3, 15 and 17. A combination of F 400 mg/m{sup 2}/d and P 15 mg/m{sup 2}/d in continuous infusion with oral etoposide (100 mg/d) and hydroxyurea (500 mg/d) in 11 patients was delivered concomitantly on days 1-3 and 14-17. A clinical and radiological evaluation was performed four weeks later. Patients with objective response underwent radical hysterectomy (group A) and those with incomplete response received additional RT-CT protocol (group B). All patients had endocavitary brachytherapy at the end of treatment. After two cycles of CT there were four PR in 19 patients and 5 failures. (authors). 36 refs., 1 fig.

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. Methods Randomised trials testing curatively intended RT (≥60 Gy in >4 weeks/>50 Gy in Results 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 Conclusion RT combined with simultaneous 5-FU, cisplatin, carboplatin, and mitomycin C as single drug or combinations of 5-FU with one of the other drugs results in a large survival advantage irrespective the employed radiation schedule. If radiation therapy is used as single modality, hyperfractionation leads to a significant improvement of overall survival. Accelerated radiation therapy alone, especially when given as split course radiation schedule or extremely accelerated treatments with decreased total dose, does not increase overall survival.

    Plerixafor, a recently approved peripheral blood progenitor cell mobilizing agent, is often added to granulocyte-colony stimulating factor (G-CSF) to mobilize peripheral blood progenitor cells in patients with lymphoma or myeloma who cannot mobilize enough CD34+ cells with G-CSF alone to undergo autologous stem cell transplantation. However, data are lacking regarding the feasibility and efficacy of just-in-time plerixafor in combination with chemotherapy and G-CSF. We reviewed the peripheral blood stem cell collection data of 38 consecutive patients with lymphoma (Hodgkin's and non-Hodgkin's) and multiple myeloma who underwent chemomobilization and high-dose G-CSF and just-in-time plerixafor to evaluate the efficacy of this treatment combination. All patients with multiple myeloma and all but one patient with lymphoma collected the minimum required number of CD34+ cells to proceed with autologous stem cell transplantation (>2 × 10(6) /kg of body weight). The median CD34+ cell dose collected in patients with non-Hodgkin lymphoma was 4.93 × 10(6) /kg of body weight. The median CD34+ cell dose collected for patients with multiple myeloma was 8.81 × 10(6) /kg of body weight. Plerixafor was well tolerated; no grade 2 or higher non-hematologic toxic effects were observed. Copyright © 2013 Wiley Periodicals, Inc.

    Repeated administration of antineoplastic chemotherapeutic agents is generally considered to induce and/or select for drug resistant cells. The authors recently begun to investigate whether chemotherapy interdigitated with radiation can minimize or eliminate the emergence of drug resiistent cells in 9L rat brain tumor spheroids grown from defined mixtures of cells sensitive (9L) and resistant (R/sub 3/) to BCNU. In this experimental system, the sister chromatid exchange (SCE) assay is used to quantitate the proportions of sensitive and resistant cells within the spheroids. While 9L and R/sub 3/ cell have different sensitivities to BCNU, they are equally sensitive to radiation. Mixed-cell spheroids consisting of 1% R/sub 3/ cells were treated with three doses of BCNU (10 μM) every 72 hr resulting in a shift in the 9L to R/sub 3/ ratio to greater than 50% R/sub 3/ cells. The combined protocols to be investigated will involve γ rays administered either 36 hr before or after each BCNU treatment. By initiating these combined protocols on spheroids of different sizes, the effectiveness of each protocol is evaluated with respect to the number of resistant cells present

    Radiofrequency ablation (RFA) combined with chemotherapy has a certain short-term therapeutic effect for the treatment of advanced non-small cell lung cancer (NSCLC), but whether it can improve the long-term survival rate of patients is still controversy. This study retrospectively analyzed the difference of long-term efficacy between RFA combined with chemotherapy and chemotherapy alone in the treatment of patients with advanced NSCLC. A total of 77 patients with stage IIIb and stage IV NSCLC who underwent radiofrequency ablation and chemotherapy in the Department of Thoracic Surgery, Xuanwu Hospital, Capital University of Medical Sciences from September 2009 to December 2015 were enrolled as the treatment group. Chemotherapy with no radiofrequency ablation was performed in 56 patients with stage IIIb and stage IV NSCLC as the control group. Two groups of patients were followed up by telephone about their living conditions. "Survival" package of R software version 3.4.1 was used for statistical analysis. Two sets of data baseline levels were tested by chi-square test. The bias was processed by Cox regression model and the survival curve was plotted using covariate mean substitution method. The first-year survival rate of the treatment group was 70.74%, the two-year survival rate was 39.31% and the median survival time was 22.1 months. The one-year survival rate was 54.54% in the control group, the two-year survival rate was 19.49%, the median survival for 18.1 months. The long-term survival rate of the treatment group was better than that of the control group (PRadiofrequency ablation of lung cancer combined with chemotherapy can significantly improve the 2-year survival rate of patients with stage IIIb and stage IV NSCLC.

    Full Text Available Background: The objective was to evaluate the cost-effectiveness of NEPA, an oral fixed combination netupitant (NETU, 300 mg and palonosetron (PA, 0.5 mg compared with aprepitant and palonosetron (APPA or palonosetron (PA alone, to prevent chemotherapy-induced nausea and vomiting (CINV in patients undergoing treatment with highly or moderately emetogenic chemotherapy (HEC or MEC in the UK. Scope: A systematic literature review and meta-analysis were undertaken to compare NEPA with currently recommended anti-emetics. Relative effectiveness was estimated over the acute (day 1 and overall treatment (days 1–5 phases, taking complete response (CR, no emesis and no rescue medication and complete protection (CP, CR and no more than mild nausea [VAS scale <25 mm] as primary efficacy outcomes. A three-health-state Markov cohort model, including CP, CR and incomplete response (no CR for HEC and MEC, was constructed. A five-day time horizon and UK NHS perspective were adopted. Transition probabilities were obtained by combining the response rates of CR and CP from NEPA trials and odds ratios from the meta-analysis. Utilities of 0.90, 0.70 and 0.24 were defined for CP, CR and incomplete response, respectively. Costs included medications and management of CINV-related events and were obtained from the British National Formulary and NHS Reference Costs. The expected budgetary impact of NEPA was also evaluated. Findings: In HEC patients, the NEPA strategy was more effective than APPA (quality-adjusted life days [QALDs] of 4.263 versus 4.053; incremental emesis-free and CINV-free days of +0.354 and +0.237, respectively and was less costly (£80 versus £124, resulting in NEPA being the dominant strategy. In MEC patients, NEPA was cost effective, cumulating in an estimated 0.182 extra QALDs at an incremental cost of £6.65 compared with PA. Conclusion: Despite study limitations (study setting, time horizon, utility measure, the results suggest NEPA is cost

    Fatal chemotherapy-induced hepatitis B virus reactivation (HBV-R) is a well-described serious complication observed in patients with lymphoma and resolved HBV infection. The aim of the present study was to determine the predictive factors of the development of chemotherapy-induced HBV-R. A total of 77 consecutive newly diagnosed patients with lymphoma and resolved HBV infection, who received chemotherapy from 2007 through 2015 were analysed retrospectively. Significant predictive factors associated with HBV-R were identified based on the data from these patients. Ten patients developed HBV-R during and following chemotherapy, and two of these 10 patients developed HBV-associated hepatitis flares. There was a significant negative correlation between anti-hepatitis B core (HBc) titres prior to chemotherapy and time to HBV-R (P=0.016, R=−0.732). Univariate and multivariate logistic regression analyses demonstrated that anti-HBc and anti-hepatitis B surface (HBs) titres at baseline were significant predictive factors for HBV-R. In addition, patients with high anti-HBc titres at baseline (above 10 S/CO) were significantly more likely to experience HBV-R than patients with low anti-HBc and high anti-HBs titres (above 28 mIU/ml), who did not experience complete reactivation (PHBV-R than those with high anti-HBs titres (P=0.031). All HBV-R episodes among the patients with high anti-HBc titres occurred within 3 months following the initiation of chemotherapy. The combination of anti-HBc and anti-HBs titres, as opposed to either titre alone, at baseline in patients with lymphoma may serve as a surrogate marker for the occurrence of HBV-R under the influence of chemotherapy.

    Objectives Erlotinib, the first generation of epidermoid growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), has been recommended as an essential treatment in patients with non-small-cell lung cancer (NSCLC) with EGFR mutation. Although it has improved progression-free survival (PFS), overall survival (OS) was limited and erlotinib can be expensive. This cost-effectiveness analysis compares erlotinib monotherapy with gemcitabine-included doublet chemotherapy. Setting First-line treatment of Asian patients with NSCLC with EGFR mutation. Methods A Markov model was created based on the results of the ENSURE (NCT01342965) and OPTIMAL (CTONG-0802) trials which evaluated erlotinib and chemotherapy. The model simulates cancer progression and all causes of death. All medical costs were calculated from the perspective of the Chinese healthcare system. Main outcome measures The primary outcomes are costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs). Results The combined PFS was 11.81 months and 5.1 months for erlotinib and chemotherapy, respectively, while the OS was reversed at 24.68 months for erlotinib and 26.16 months for chemotherapy. The chemotherapy arm gained 0.13 QALYs compared with erlotinib monotherapy (1.17 QALYs vs 1.04 QALYs), while erlotinib had lower costs ($55 230 vs $77 669), resulting in an ICER of $174 808 per QALY for the chemotherapy arm, which exceeds three times the Chinese GDP per capita. The most influential factors were the health utility of PFS, the cost of erlotinib and the health utility of progressed disease. Conclusion Erlotinib monotherapy may be acceptable as a cost-effective first-line treatment for NSCLC compared with gemcitabine-based chemotherapy. The results were robust to changes in assumptions.

    Full Text Available This communication states the changing patterns of Salmonella enterica serovar Typhi (S. Typhi isolates causing enteric fever in and around Kolkata, India. 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. Typhi isolates having decreased sensitivity to cp (MICs: 0.5–1.25 μg mL−1.

    Combination therapy with S-1, superselective intra-arterial infusion of carboplatin (CBDCA) and radiation therapy has been used to treat patients with oral cancer since 2005. In this study, the histopathological effects and toxicities following concurrent chemoradiotherapy were examined. The subjects consisted of 15 patients (10 men and 5 women) who were treated with S-1 (60-80 mg/day, 4 weeks), superselective intra-arterial infusion of CBDCA (300 mg/body) and radiation therapy (total dose 30-36 Gy) in our department from 2005 to 2009. Nine patients, showed T2 disease, 3 showed T3 disease, and another 3 showed T4 diseases. The primary cancer sites were the tongue (6 cases), buccal mucosa (4 cases), mandible gingival (3 cases), maxillary gingival (1 case), and the floor of the mouth (1 case). The histopathological effects were evaluated according to Oboshi-Shimosato classification. Grade IV was shown in 10 cases (66.7%), grade III in 1 case (6.7%), II bin 3 cases (20.0%), and II a in 1 case (6.7%). All patients completed the treatment. The pathological response of the resected tumor was grade IIb or higher in 14 cases (93.3%). While good histological effects were noted, there was one patient for whom viable tumor cells remained in the central part of the tumor. The present study indicates that further investigation is needed to determine the best dosing and dosing schedule. (author)

    Full Text Available Recent advances in next-generation sequencing and other omics technologies capable to map cell fate provide increasing evidence on the crucial role of intra-tumor heterogeneity (ITH for cancer progression. The different facets of ITH, from genomic to microenvironmental heterogeneity and the hierarchical cellular architecture originating from the cancer stem cell compartment, contribute to the range of tumor phenotypes. Decoding these complex data resulting from the analysis of tumor tissue complexity poses a challenge for developing novel therapeutic strategies that can counteract tumor evolution and cellular plasticity. To achieve this aim, the development of in vitro and in vivo cancer models that resemble the complexity of ITH is crucial in understanding the interplay of cells and their (microenvironment and, consequently, in testing the efficacy of new targeted treatments and novel strategies of tailoring combinations of treatments to the individual composition of the tumor. This challenging approach may be an important cornerstone in overcoming the development of pharmaco-resistances during multiple lines of treatment. In this paper, we report the latest advances in patient-derived 3D (PD3D cell cultures and patient-derived tumor xenografts (PDX as in vitro and in vivo models that can retain the genetic and phenotypic heterogeneity of the tumor tissue.

    The results of radiation therapy alone or combined with surgery and/or chemotherapy are reported for 47 patients who presented with local and/or regional recurrence without evidence of distant metastases following initial management of adenocarcinoma of the breast with radical or modified radical mastectomy (43) or simple mastectomy (4). Patients were treated between October 1964 and March 1983 at the University of Florida; all have a 2-year minimum follow-up and 42/47 (89%) have had follow-up for ≥5 years. The overall actuarial local-regional control rates were 80% at 2 years, 68% at 5 years, and 61% at 10 years. The 5-year actuarial local-regional control rates by site and extent of disease were as follows: single chest wall nodule, 92%; multiple chest wall nodules, 49%; regional lymph nodes, 66%; and multiple sites, 64%. The 5- and 10-year actuarial determinate disease-free survival rates for all patients were 41 and 17%, respectively. The 5- and 10-year actuarial survival rates for all patients were 50 and 34%, respectively. 22 refs.; 5 figs.; 5 tabs

    The aim of this study was to assess feasibility and efficacy of weekly concomitant boost accelerated postoperative radiation therapy (PORT) with concomitant chemotherapy (CT) in patients with locally advanced head and neck cancer (LAHNC). Conformal or intensity-modulated 66-Gy RT was performed in 5.5 weeks in 40 patients. Cisplatin was given at days 1, 22, and 43. Median follow-up was 36 months. Grade 3 mucositis, dysphagia, and erythema was observed in ten (25%), nine (23%), and six (13%) patients, respectively. Grade 3 or more anemia was observed in two (6%) patients, and leukopenia in five (13%) patients. No grade 3 or 4 thrombocytopenia was observed. Grade 3 nephrotoxicity was observed in one patient (3%). No treatment-related mortality was observed. Grade 2 or more xerostomia and edema were observed in ten (25%) and one (3%) patient, respectively. Locoregional relapse occurred in eight patients, and seven patients developed distant metastases. Median time to locoregional relapse was 6 months. Three-year overall, disease-free survival, and locoregional control rates were 63%, 62%, and 81%, respectively. Multivariate analysis revealed that the only prognostic factor was nodal status. Reducing overall treatment time using accelerated PORT/CT by weekly concomitant boost (six fractions per week) combined with concomitant cisplatin CT is easily feasible with acceptable morbidity.

    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.

    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

    A 22-year old man with germinal cell tumor originating in the anterior mediastinum was treated with the VAB-6 chemotherapy. Disappearance of tumor cells and degeneration to fibrous necrotic tissue was revealed by MRI performed after chemotherapy, i.e. change of T 2 weighted image of the tumor from high-intensity to iso-intensity. And this pathological change was confirmed by the histological examination of the resected specimen. MRI was considered to be very useful to evaluate the effect of chemotherapy for germinal cell tumor originating in the anterior mediastinum. (author)

    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

    Purpose: The purpose of this study was to compare the severity and distribution of the toxicities associated with the two different combinations of chemotherapy and radiotherapy. Methods and Materials: This prospective randomized trial studied toxicities associated with induction chemotherapy followed by concurrent treatment (Arm 1) vs. immediate concurrent chemotherapy/radiotherapy (CT/RT) (Arm 2). Arm 1 consisted of vinblastine (VB), 5 mg/M 2 IV bolus weekly, weeks 1-5 and cisplatin (DDP), 100 mg/M 2 days 1 and 29, DDP 75 mg/M 2 , days 50, 71, and 92. Daily RT started on day 50; a total dose of 63 Gy was given in 34 fractions in 7 weeks. In Arm 2 RT started day 1; a total dose of 69.6 Gy was given in 58 fractions of 1.2 Gy bid, 5 days per week for 6 weeks with DDP 50 mg/M 2 i.v. days 1 and 8, and oral VP-16 50 mg b.i.d. during the first 10 days of RT. DDP/VP-16 were repeated beginning day 29. Survival was used as the Phase II endpoint. Results: Between July 1992 and February 1994, 168 patients were randomized; 162 evaluable patients had minimum follow-up of 20 months. Eighty patients were registered to Arm 1 and 82 to Arm 2. Pretreatment characteristics were distributed evenly. Arm 1 had significantly more Grade 4 hematologic toxicity (62%) than Arm 2 (33%) (p = 0.021). Acute nonhematologic Grade 3+ toxicity was also greater (p = 0.018) in Arm 2 than Arm 1 due mainly to esophagitis (38 vs. 6%; p < 0.0001). Grade 3+ late esophageal toxicity was 12% on Arm 2 compared to 3% on Arm 1 (p = 0.006). There were no differences between the two arms in compliance with protocol specifications for either RT or CT. At 1 year, 31.7% of patients had in-field progression on Arm 1 compared to 19.8% on Arm 2 (p = 0.042), but overall progression-free survival rates were nearly identical; 50 and 49% for Arms I and II, respectively, at 12 months. One-year and median survivals were 65% and 15.5 months on Arm 1 compared to 58% and 14.4 months on Arm 2. Conclusion: Whereas hematologic

    There is no research regarding the appropriate antiemetic agents for female patients, especially those receiving moderately emetogenic chemotherapy (MEC). We evaluated the antiemetic efficacy of a combination of 5-HT₃ receptor with/without aprepitant in patients with gynecological cancer treated with the TC (paclitaxel and carboplatin) regimen of MEC. We enrolled 38 patients diagnosed with gynecologic cancer and scheduled to receive the TC regimen. The patients were randomly assigned to receive a 5-HT₃ receptor antagonist, either palonosetron in the first cycle followed by granisetron in the second cycle or vice versa. In the third cycle, all patients received a combination of the 5-HT₃ receptor and dexamethasone with/without aprepitant. When three drugs were administered, palonosetron consistently produced an equivalent complete response (CR) rate to granisetron in the acute phase (89.5% vs. 86.8%, p=0.87) and delayed phase (60.5% vs. 65.8%, p=0.79). With regard to the change in dietary intake, palonosetron exhibited similar efficacy to granisetron in the acute phase (92.1% vs. 89.4%, p=0.19) and delayed phase (65.7% vs. 68.4%, p=0.14). However, in the delayed phase, the addition of aprepitant therapy with a 5-HT₃ receptor antagonist and dexamethasone produced a higher CR rate than a 5-HT₃ receptor antagonist with dexamethasone (93.3% vs. 47.8%, p<0.001) and allowed the patients to maintain a higher level of dietary intake (93.3% vs. 56.5%, p<0.001). The addition of aprepitant therapy was more effective than the control therapy of a 5-HT₃ receptor antagonist, and dexamethasone in gynecological cancer patients treated with the TC regimen.

    Aim of the study is to assess the reliability and correlation with surgical peritoneal cancer index (PCI) of combined PET/CT and ceCT scans (PET/ceCT) performed in a session in patients with peritoneal carcinomatosis candidates for cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC). We retrospectively analyzed data collected from 27 patients with different types of peritoneal carcinomatosis candidates to CS + HIPEC who underwent FDG PET/ceCT in a single session. Two nuclear medicine physicians and two radiologists independently and blindly evaluated PET/CT and ceCT imaging, respectively. In the case of discordance, the consensus was reached by a discussion between the specialists. Moreover, the combined images were evaluated by all the specialists in consensus. The PCIs obtained from surgical look, PET/CT, ceCT, and PET/ceCT were compared with each other. The coefficients of correlation (r) were calculated. The study was conducted after approval of local ethics committee. Surgical PCI was available in 21 patients. The coefficient of correlation between PCI of PET/CT and surgery was 0.528, while it resulted higher between PET/ceCT and surgery (r = 0.878), very similar to ceCT and surgery (r = 0.876). The r coefficient between surgical PCI and PET/CT was higher in patients with a non-mucinous cancer (n = 12) than the counterpart (0.601 vs. 0.303) and the addition of ceCT significantly increases the correlation (r = 0.863), which is anyway similar to ceCT alone (r = 0.856). PET/ceCT as single examination is more accurate than PET/CT but not than ceCT alone for the definition of PCI in a selected group of patients candidates to CS + HIPEC.

    Full Text Available Abstract Background Combining trastuzumab and chemotherapy is standard in her2/neu overexpressing advanced breast cancer. It is not established however, whether trastuzumab treatment should continue after the failure of one earlier combination. In this trial, we report our experience with continued treatment beyond disease progression. Methods Fifty-four patients, median age 46 years, range 25–73 years, were included. We analysed for time to tumour progression (TTP for first, second and beyond second line treatment, response rates and overall survival. Results Median time of observation was 24 months, range 7–51. Response rates for first line treatment were 7.4% complete remission (CR, 35.2% partial remissions (PR, 42.6% stable disease > 6 months (SD and 14.8% of patients experienced disease progression despite treatment (PD. Corresponding numbers for second line were 3.7% CR, 22.2% PR, 42.6% SD and 31.5% PD; numbers for treatment beyond second line (60 therapies, 33 pts 3rd line, 18 pts 4th line, 6 pts 5th line, 2 pts 6th line and 1 patient 7th line were 1.7% CR, 28.3% PR, 28.3% SD and 41.6% PD respectively. Median TTP was 6 months (m in the first line setting, and also 6 m for second line and beyond second line. An asymptomatic drop of left ventricular ejection fraction below 50% was observed in one patient. No case of symptomatic congestive heart failure was observed. Conclusion The data presented clearly strengthen evidence that patients do profit from continued trastuzumab treatment. The fact that TTP did not decrease significantly from first line to beyond second line treatment is especially noteworthy. Still, randomized trials are warranted.

    In an attempt to improve the prognosis of brain stem glioma patients, a new treatment using a combination of chemotherapy of interferon-{beta}, ACNU, (1) - (4 - Amino - 2 - methyl - 5 - primidinyl) - methyl - 3 - (2-chloroethyl) - 3 -nitrosourea hydrochloride, and radiation, so called IAR therapy, was utilized on 19 patients who were diagnosed through CT and/or MRI findings as having pontine glioma. Eight of these patients were given IAR therapy at four week intervals and the changes were checked on MRI. The MRI response was classified into 3 types, that is, type 1: diffuse low intensity lesion on T{sub 1} WI changing to isodensity and tumor mass disappearing rapidly; type 2: located high intensity lesion in low intensity on T{sub 1} WI once appearing on decreasing the whole tumor size, then this lesion disappearing gradually; type 3: spotted low and/or iso mosaic intensity lesion appearing on and after treatment, with little change in tumor mass. The type 1 patients showed rapid improvement of neurological deficits and good recovery was obtained. Type 2 patients also recovered well but at recurrent periods tended to show disseminated sings intraspinally. The type 3 patients did not recover from neurological deficits well. But there were no significant differences of prognosis among these 3 types. Furthermore, MRI showed more precise data than CT scan on brain stem lesions and seemed to be more useful for diagnosis and follow-up treatment than CT scan. Though it is suggested that IAR combination therapy should be respected as the first choice for the treatment of brain stem glioma, it is strongly requested that some maintenance therapy is established for continuing the reduction time after induction of complete or partial remission with IAR therapy.

    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 18 F-FDG PET/CT and MRI examinations before and during NAC. The imaging features evaluated on both examinations included baseline and changes in 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.)

    Traditional Chinese Medicine (tcm) is used in China as part of the treatment for non-small-cell lung cancer (nsclc) and often includes prescription of herbal therapy based on syndrome differentiation. Studies of various Astragalus-based Chinese medicines combined with platinum-based chemotherapy in the treatment of lung cancer are popular in East Asia, particularly in China. The aim of the present study was to perform a systematic review and meta-analysis comparing platinum-based chemotherapy alone with platinum-based chemotherapy plus Astragalus-based Chinese botanicals, with and without prescription based on syndrome differentiation, as first-line treatment for advanced nsclc. We searched the Chinese Biomedical Literature database, the China National Knowledge Internet, the VIP Chinese Science and Technology Periodicals Database, PubMed, embase, the Cochrane databases, and abstracts presented at meetings of the American Society of Clinical Oncology, the World Conference on Lung Cancer, the European Society for Medical Oncology, and the Chinese Society of Clinical Oncology for all eligible studies. Endpoints were overall survival; 1-year, 2-year, and 3-year survival rates; performance status; overall response rate; and grade 3 or 4 adverse events. Subgroup analyses based on herbal formulae individualized using syndrome differentiation or on oral or injection patent medicines were performed using the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.) and a fixed-effects or random-effects model in case of heterogeneity. Results are expressed as a hazard ratio (hr) or relative risk (rr), with corresponding 95% confidence intervals (cis). Seventeen randomized studies with scores on the Jadad quality scale of 2 or more, representing 1552 patients, met the inclusion criteria. Compared with platinum-based chemotherapy alone, the addition of Astragalus-based tcm to chemotherapy was associated with significantly increased overall survival

    DNA methylation changes are a constant feature of acute myeloid leukemia. Hypomethylating drugs such as azacitidine are active in acute myeloid leukemia (AML) as monotherapy. Azacitidine monotherapy is not curative. The AML-AZA trial tested the hypothesis that DNA methyltransferase inhibitors such as azacitidine can improve chemotherapy outcome in AML. This randomized, controlled trial compared the efficacy of azacitidine applied before each cycle of intensive chemotherapy with chemotherapy alone in older patients with untreated AML. Event-free survival (EFS) was the primary end point. In total, 214 patients with a median age of 70 years were randomized to azacitidine/chemotherapy (arm-A) or chemotherapy (arm-B). More arm-A patients (39/105; 37%) than arm-B (25/109; 23%) showed adverse cytogenetics (P=0.057). Adverse events were more frequent in arm-A (15.44) versus 13.52 in arm-B, (P=0.26), but early death rates did not differ significantly (30-day mortality: 6% versus 5%, P=0.76). Median EFS was 6 months in both arms (P=0.96). Median overall survival was 15 months for patients in arm-A compared with 21 months in arm-B (P=0.35). Azacitidine added to standard chemotherapy increases toxicity in older patients with AML, but provides no additional benefit for unselected patients.

    The aim of this non-randomized controlled trial was to compare time to progression (TTP), lymphoma-specific survival (LSS), and safety of an autologous vaccine (consisting of hydroxyapatite ceramic powder and Heat Shock Proteins purified from the dogs' tumors, HSPPCs-HA) plus chemotherapy versus chemotherapy alone in dogs with newly diagnosed, clinically advanced, histologically confirmed, multicentric indolent B-cell lymphoma. The vaccine was prepared from dogs' resected lymph nodes and administered as an intradermal injection. Forty-five client-owned dogs were enrolled: 20 dogs were treated with dose-intense chemotherapy, and 25 received concurrent immunotherapy. Both treatment arms were well tolerated, with no exacerbated toxicity in dogs also receiving the vaccine. TTP was significantly longer for dogs treated with chemo-immunotherapy versus those receiving chemotherapy only (median, 209 versus 85 days, respectively, P=0.015). LSS was not significantly different between groups: dogs treated with chemo-immunotherapy had a median survival of 349 days, and those treated with chemotherapy only had a median survival of 200 days (P=0.173). Among vaccinated dogs, those mounting an immune response had a significantly longer TTP and LSS than those with no detectable response (P=0.012 and P=0.003, respectively). Collectively these results demonstrate that vaccination with HSPPCs-HA may produce clinical benefits with no increased toxicity, thereby providing a strategy for enhancing chemotherapy in dogs with advanced indolent lymphoma.

    Between 1983 and 1986, the National Institute for Cancer Research in Genoa and affiliated institutions conducted a randomized study to compare two different ways of combining chemotherapy (CT) and radiation therapy (RT). One hundred sixteen patients were randomized to receive neoadjuvant CT followed by definitive RT (treatment arm A) or alternating CT and RT. In treatment arm A, RT consisted of 70 Gy to the involved areas and 50 Gy to the uninvolved neck at 2 Gy/fraction, five fractions per week. In treatment arm B, RT consisted of 60 Gy to involved areas and 50 Gy to the uninvolved neck in three courses of 20 Gy each, 2 Gy/fraction, ten fractions/2 weeks alternated with four courses of CT. CT consisted of vinblastine 6 mg/m2 intravenously followed 6 hours later by bleomycin 30 IU intramuscularly, day 1; methotrexate 200 mg intravenously, day 2; leucovorin rescue, day 3. CT was repeated every 2 weeks up to four courses. The same CT was used in both treatment arms of the study. Fifty-five patients were entered in treatment arm A and 61 in treatment arm B. Complete responses were 7/48 and 19/57 in treatment arms A and B, respectively (P less than 0.03). Four-year progression-free survival was 4% in treatment arm A and 12% in treatment arm B (P less than 0.02), and four-year survival was 10% in A and 22% in B (P less than 0.02). Mucosal tolerance was significantly worse in treatment arm B (P less than 0.00004). The subgroup analysis shows the major improvement of alternating CT and RT in patients with the worst prognostic characteristics

    The aim of this study is to outline a general process for assessing the feasibility of performing a valid network meta-analysis (NMA) of randomized controlled trials (RCTs) to synthesize direct and indirect evidence for alternative treatments for a specific disease population. Several steps to assess the feasibility of an NMA are proposed based on existing recommendations. Next, a case study is used to illustrate this NMA feasibility assessment process in order to compare everolimus in combination with hormonal therapy to alternative chemotherapies in terms of progression-free survival for women with advanced breast cancer. A general process for assessing the feasibility of an NMA is outlined that incorporates explicit steps to visualize the heterogeneity in terms of treatment and outcome characteristics (Part A) as well as the study and patient characteristics (Part B). Additionally, steps are performed to illustrate differences within and across different types of direct comparisons in terms of baseline risk (Part C) and observed treatment effects (Part D) since there is a risk that the treatment effect modifiers identified may not explain the observed heterogeneity or inconsistency in the results due to unexpected, unreported or unmeasured differences. Depending on the data available, alternative approaches are suggested: list assumptions, perform a meta-regression analysis, subgroup analysis, sensitivity analyses, or summarize why an NMA is not feasible. The process outlined to assess the feasibility of an NMA provides a stepwise framework that will help to ensure that the underlying assumptions are systematically explored and that the risks (and benefits) of pooling and indirectly comparing treatment effects from RCTs for a particular research question are transparent.

    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/m 2 weekly for 3 weeks followed by 1 week rest then 5-6 weeks of radiotherapy and concurrent CI 5FU (200 mg/m 2 /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

    In locally advanced rectal cancer (LARC) preoperative chemoradiation (CRT) is the standard of care, but the risk of local recurrence is low with good quality total mesorectal excision (TME), although many still develop metastatic disease. Current challenges in treating rectal cancer include the development of effective organ-preserving approaches and the prevention of subsequent metastatic disease. Neoadjuvant systemic chemotherapy (NACT) alone may reduce local and systemic recurrences, and may be more effective than postoperative treatments which often have poor compliance. Investigation of intensified NACT is warranted to improve outcomes for patients with LARC. The objective is to evaluate feasibility and efficacy of a four-drug regimen containing bevacizumab prior to surgical resection. This is a multi-centre, randomized phase II trial. Eligible patients must have histologically confirmed LARC with distal part of the tumour 4–12 cm from anal verge, no metastases, and poor prognostic features on pelvic MRI. Sixty patients will be randomly assigned in a 1:1 ratio to receive folinic acid + flurourcil + oxaliplatin (FOLFOX) + bevacizumab (BVZ) or FOLFOX + irinotecan (FOLFOXIRI) + BVZ, given in 2 weekly cycles for up to 6 cycles prior to TME. Patients stop treatment if they fail to respond after 3 cycles (defined as ≥ 30 % decrease in Standardised Uptake Value (SUV) compared to baseline PET/CT). The primary endpoint is pathological complete response rate. Secondary endpoints include objective response rate, MRI tumour regression grade, involved circumferential resection margin rate, T and N stage downstaging, progression-free survival, disease-free survival, overall survival, local control, 1-year colostomy rate, acute toxicity, compliance to chemotherapy. In LARC, a neoadjuvant chemotherapy regimen - if feasible, effective and tolerable would be suitable for testing as the novel arm against the current standards of short course preoperative radiotherapy (SCPRT

    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

    We conducted an open-label, single-arm Phase I/II clinical trial in metastatic CRPC (mCRPC) patients eligible for docetaxel combined with treatment with autologous mature dendritic cells (DCs) pulsed with killed LNCaP prostate cancer cells (DCVAC/PCa). The primary and secondary endpoints were safety and immune responses, respectively. Overall survival (OS), followed as a part of the safety evaluation, was compared to the predicted OS according to the Halabi and MSKCC nomograms. Twenty-five patients with progressive mCRPC were enrolled. Treatment comprised of initial 7 days administration of metronomic cyclophosphamide 50 mg p.o. DCVAC/PCa treatment consisted of a median twelve doses of 1 × 107 dendritic cells per dose injected s.c. (Aldara creme was applied at the site of injection) during a one-year period. The initial 2 doses of DCVAC/PCa were administered at a 2-week interval, followed by the administration of docetaxel (75 mg/m2) and prednisone (5 mg twice daily) given every 3 weeks until toxicity or intolerance was observed. The DCVAC/PCa was then injected every 6 weeks up to the maximum number of doses manufactured from one leukapheresis. No serious DCVAC/PCa-related adverse events have been reported. The median OS was 19 months, whereas the predicted median OS was 11.8 months with the Halabi nomogram and 13 months with the MSKCC nomogram. Kaplan-Meier analyses showed that patients had a lower risk of death compared with both MSKCC (Hazard Ratio 0.26, 95% CI: 0.13-0.51) and Halabi (Hazard Ratio 0.33, 95% CI: 0.17-0.63) predictions. We observed a significant decrease in Tregs in the peripheral blood. The long-term administration of DCVAC/PCa led to the induction and maintenance of PSA specific T cells. We did not identify any immunological parameter that significantly correlated with better OS. In patients with mCRPC, the combined chemoimmunotherapy with DCVAC/PCa and docetaxel was safe and resulted in longer than expected survival. Concomitant chemotherapy

    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.

    Despite the improvements in diagnosis and treatment, colorectal cancer (CRC) is the second cause of cancer deaths in both sexes. Therefore, research in this field remains of great interest. The approval of bevacizumab, a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody, in combination with a fluoropyrimidine-based chemotherapy in the treatment of metastatic CRC has changed the oncology practice in this disease. However, the efficacy of bevacizumab-based treatment, has thus far been rather modest. Efforts are ongoing to understand the better way to combine bevacizumab and chemotherapy, and to identify valid predictive biomarkers of benefit to avoid unnecessary and costly therapy to nonresponder patients. The BRANCH study in high-risk locally advanced rectal cancer patients showed that varying bevacizumab schedule may impact on the feasibility and efficacy of chemo-radiotherapy. OBELICS is a multicentre, open-label, randomised phase 3 trial comparing in mCRC patients two treatment arms (1:1): standard concomitant administration of bevacizumab with chemotherapy (mFOLFOX/OXXEL regimen) vs experimental sequential bevacizumab given 4 days before chemotherapy, as first or second treatment line. Primary end point is the objective response rate (ORR) measured according to RECIST criteria. A sample size of 230 patients was calculated allowing reliable assessment in all plausible first-second line case-mix conditions, with a 80% statistical power and 2-sided alpha error of 0.05. Secondary endpoints are progression free-survival (PFS), overall survival (OS), toxicity and quality of life. The evaluation of the potential predictive role of several circulating biomarkers (circulating endothelial cells and progenitors, VEGF and VEGF-R SNPs, cytokines, microRNAs, free circulating DNA) as well as the value of the early [(18)F]-Fluorodeoxyglucose positron emission tomography (FDG-PET) response, are the objectives of the traslational project.

    Purpose/Objective: To demonstrate feasibility and efficacy of induction chemotherapy followed by concomitant daily irradiation and carboplatine in the treatment of stage IIIB NSCLC patients. Materials and Methods : Were eligible previously untreated patients with histological y proven stage IIIB NSCLC, aged ≤ 75 years, WHO performance status (PS) ≤ 2, neutrophil count ≥ 2000 and platelets ≥ 150,000, and with no renal or hepatic insufficiency. Patients with large tumor volume which could not be irradiated, were excluded from this phase II study. Induction chemotherapy (CT) consisted of navelbine (NVB) and cisplatin (CDDP) administered over a 8 week period. NVB 30 mg/m 2 was given on weeks 1, 2, 4, 5, 6, 8 and 9; NVB 15 mg/m 2 on weeks 3 and 7; CDDP 120 mg/m 2 was given on weeks 1, 5 and 9. Patients free of distant progression after induction CT received megavoltage radiation (66 Gy, 2 Gy/fraction) along with daily CBDCA (15 mg/m 2 ) given 2 to 4 hours before irradiation. Adjuvant NVB-CDDP chemotherapy (2 cycles) was administered in patients still progression-free. Evaluation was performed at the end of induction CT (week 10) and 3 months after the end of irradiation. The Kaplan-Meier method was used to estimate survival rate with time at risk starting the first day of induction CT. Results : From February 1994 to January 1996, 111 patients were enrolled in 8 centers of whom 76 were eligible for analysis at March 1, 1996. Initial characteristics were : male/female ratio (68(8)), mean age 59 (39 to 76), PS 0 : 40%, PS 1 : 49%, PS 2 : 11%, squamous carcinoma 67%. Observed to theoretical dose ratios of NVB and CDDP as induction CT were 83% and 86%, respectively. Hematological grade 3-4 toxicity was observed in 79% of patients; other grade 3-4 toxicities were nausea in 21%, diarrhea in 3%, alopecia in 2% and sepsis in 5% of patients. Seven (9%) patients died before first evaluation. After induction CT, 3 patients were in complete remission (CR), 35 in partial

    Simultaneous treatment utilizing pulsed radiowave and cancer chemotherapy significantly extended the life span of mice with Lewis lung transplanted carcinoma. In comparison with nontreated controls, the combination of hydroxyurea and whole body nonionizing EM radiation (at 27.12 MHz) produced differential enhancement of longevity depending on hydroxyurea combined with highest power output achieved by pulsing the radiation 600 times per second; at a 3.9% duty cycle, peak watts = 975 produced the mean extension of life 67% greater than that of the group treated with hydroxyurea alone.

    To determine diagnostic performance of diffusion-weighted (DW) magnetic resonance (MR) imaging for assessment of complete tumor response (CR) after combined radiation therapy with chemotherapy (CRT) in patients with locally advanced rectal cancer (LARC) by means of volumetric signal intensity measurements and apparent diffusion coefficient (ADC) measurements and to compare the performance of DW imaging with that of T2-weighted MR volumetry. A retrospective analysis of 50 patients with LARC, for whom clinical and imaging data were retrieved from a previous imaging study approved by the local institutional ethical committee and for which all patients provided informed consent, was conducted. Patients underwent pre- and post-CRT standard T2-weighted MR and DW MR. Two independent readers placed free-hand regions of interest (ROIs) in each tumor-containing section on both data sets to determine pre- and post-CRT tumor volumes and tumor volume reduction rates (volume). ROIs were copied to an ADC map to calculate tumor ADCs. Histopathologic findings were the standard of reference. Receiver operating characteristic (ROC) curves were generated to compare performance of T2-weighted and DW MR volumetry and ADC. The intraclass correlation coefficient (ICC) was used to evaluate interobserver variability and the correlation between T2-weighted and DW MR volumetry. Areas under the ROC curve (AUCs) for identification of a CR that was based on pre-CRT volume, post-CRT volume, and volume, respectively, were 0.57, 0.70, and 0.84 for T2-weighted MR versus 0.63, 0.93, and 0.92 for DW MR volumetry (P = .15, .02, .42). Pre- and post-CRT ADC and ADC AUCs were 0.55, 0.54, and 0.51, respectively. Interobserver agreement was excellent for all pre-CRT measurements (ICC, 0.91-0.96) versus good (ICC, 0.61-0.79) for post-CRT measurements. ICC between T2-weighted and DW MR volumetry was excellent (0.97) for pre-CRT measurements versus fair (0.25) for post-CRT measurements. Post-CRT DW MR

    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 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 cancer

    Purpose: Results of radical radiotherapy in the treatment of inoperable NSCLC can be improved by either concurrent daily low-dose Cisplatin as radiosensitizer (Shaake-Koning, N Engl J Med, 1992; 326: 524) or by using neoadiuvant chemotherapy (Dillman, N Engl J Med, 1990; 323: 940). The aim of present study was to evaluate the activity and feasibility of a new chemo-radiotherapy (CT-RT) regimen in which both strategies of RT improvement will be used. Methods: Thirty consecutive patients (pts) were treated with induction CT (Cisplatin 100 mg/m{sup 2} i.v. day 1,22 + Vinblastine 5 mg/m{sup 2} i.v. day 1,8,15,22,29) followed by RT (60 Gy/30 fractions in 6 wks) combined with Cisplatin 5 mg/m{sup 2} daily before RT. Patients' characteristics were: 29 pts were male and 1 female; median age 60.5 yrs (range 44-69); median PS 1 (range 0-1); 21 squamous cell carcinoma and 9 adenocarcinoma; stage III A in 9 pts and stage IIIB in 21 pts. Results: Twenty-three pts were evaluable for RT plus daily Cisplatin toxicity and 29 for CT toxicity (according to WHO). For RT plus daily cisplatin hematological toxicity consisted of grade III leukopenia in 22%, grade III anemia 9% and grade III thrombocytopenia in 9% of pts. Only 2 patients developed severe esophagitis. Only one case of radiation pneumonitis was reported. For induction CT hematological toxicity consisted of grade III-IV leukopenia in 31%, grade II anemia 10% and grade IV thrombocitopenia in 14% of cases. Non-hematological toxicity consisted mainly of grade I peripheral neuropaty and occured in 17% of pts. One case of minor hearing loss and 4 cases of tinnitus were observed at the end of treatment. Twenty-seven pts were evaluable for response. Response rate was 59% with 7 CRs (26%) and 9 PRs (33%); 1 patient had SD (4%), 5 pts PD (20%) and 5 pts (19%) died early (3 for early progression, 1 for toxicity and 1 for cardiac failure). All pts with CR are still alive with a median event-free survival of 23.9 months (range 12

    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.

  10. Concurrent radiotherapy and chemotherapy

    The principal objective of combining chemotherapy with radiotherapy (XRT) for the treatment of advanced head and neck cancer is to improve the therapeutic ratio through the enhancement of local control and reduction of distant metastases without excessively enhancing normal tissue effects. Improved tumour control can result from sole additivity of either therapy or direct interactions between drug and radiation leading to increased tumour cell kill. Chemotherapy may sensitize the cells to radiation, interfere with repair of sublethal or potentially lethal radiation damage, induce cell synchrony, and reduce tumour mass leading to reoxygenation and decreased fraction of resistant hypoxic cells. Radiation may improve drug accessibility to tumour cells and reduce tumour volume leading to increased cell proliferation and chemosensitivity. If the enhanced effects of combined therapy are purely additive, then the two modalities can be administered either sequentially or concurrently with the same results. However, if the enhanced effects result from the direct interaction between drug and radiation, it is necessary that the two modalities be administered concurrently and in close temporal proximity. This review summarizes the results of clinical studies in which chemotherapy was administered concurrently during the course of radiotherapy for patients with previously untreated advanced squamous cell carcinoma in the head and neck

    To investigated the influence of hyperthermal perfusion chemotherapy combined with immunologic therapy on the immunologic function and levels of circulating tumor cells of the advanced colorectal cancer patients with liver metastasis. We enrolled 98 advanced colorectal cancer patients with liver metastasis that were admitted to this hospital for treatment and were randomly divided into two groups, the observation group (n = 49) and the control group (n = 49). We administered systemic vein chemotherapy for patients in the control group, and hyperthermal perfusion chemotherapy for the patients in the observation group in order to compare the subgroup levels of T lymphocytes, NK cells and immunoglobulin (IgG, IgA, and IgM) in the immune system of patients in both groups. We also assayed the circulating tumor cells (CTC) in the peripheral blood of patients in both groups using the cell search method, and compared the efficacy using response evaluation criteria in solid tumors and the survival rates of patients in both groups using the Kaplan-Meier method. After two treatment courses, the levels of CD3+, CD4+ and CD4+/CD8+ of the patients in the observation group were significantly higher than those of the control group, but the levels of CD8+ of patients in the observation group was lower than that in the control group (pfunctions of patients for the indirect anti-tumor effect, a significant decrease in CTC of patients, and a higher long-term survival rate have been achieved in the treatment with hyperthermal perfusion chemotherapy combined with immunologic therapy for the advanced colorectal cancer patients with liver metastasis. Thus, it can serve as the preferable drug for the treatment of advanced colorectal cancer with liver metastasis.

    1983-01-01

    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

    Immunotherapy for recurrent and/or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN) is promising. The toll-like receptor 8 (TLR8) agonist motolimod may stimulate innate and adaptive immunity. To determine whether motolimod improves outcomes for R/M SCCHN when combined with standard therapy. The Active8 study was a multicenter, randomized, double-blind, placebo-controlled clinical trial enrolling adult patients (age ≥18 years) with histologically confirmed R/M SCCHN of the oral cavity, oropharynx, hypopharynx, or larynx between October 2013 and August 2015. Follow-up ended September 2016. Analysis for the present report was conducted between June 2016 and December 2017. Combination treatment with platinum (carboplatin or cisplatin), fluorouracil, cetuximab (the EXTREME regimen), and either placebo or motolimod, each administered intravenously every 3 weeks. Patients received a maximum of 6 chemotherapy cycles, after which patients received weekly cetuximab with either placebo or motolimod every 4 weeks. Progression-free survival (PFS) as determined by independent central review using immune-related RECIST (Response Evaluation Criteria in Solid Tumors). Key secondary end points included overall survival (OS) and safety. Of 195 patients enrolled, 85% were men (n = 166); 82% were white (n = 159); median age was 58 years (range 23-81 years). Median PFS was 6.1 vs 5.9 months (hazard ratio [HR], 0.99; 1-sided 90% CI, 0.00-1.22; P = .47), and median OS was 13.5 vs 11.3 months (HR, 0.95; 1-sided 90% CI, 0.00-1.22; P = .40) for motolimod vs placebo. Increased incidence of injection site reactions, pyrexia, chills, anemia, and acneiform rash were noted with motolimod. Of 83 cases oropharyngeal cancer, 52 (63%) were human papillomavirus (HPV) positive. In a prespecified subgroup analysis of HPV-positive participants, motolimod vs placebo resulted in significantly longer PFS (7.8 vs 5.9 months; HR, 0.58; 1-sided 90% CI, 0.00-0.90; P

    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

    Chemotherapy has been widely applied in clinics. However, the therapeutic potential of chemotherapy against cancer is seriously dissatisfactory due to the nonspecific drug distribution, multidrug resistance (MDR) and the heterogeneity of cancer. Therefore, combinational therapy based on chemotherapy mediated by nanotechnology, has been the trend in clinical research at present, which can result in a remarkably increased therapeutic efficiency with few side effects to normal tissues. Moreover,...

    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.

    Purpose: To evaluate the outcome in children with anaplastic ependymomas after surgery, irradiation, and chemotherapy; and to identify prognostic factors for survival. Methods and Materials: Fifty-five children (n = 27 girls, 28 boys; median age at diagnosis, 6.2 years) with newly diagnosed anaplastic ependymomas were treated in the multicenter, prospective trials HIT 88/89 and HIT 91. Macroscopic complete resection was achieved in 28 patients; 27 patients underwent incomplete resection. All patients received chemotherapy before (n = 40) or after irradiation (n = 15). The irradiation volume encompassed either the neuraxis followed by a boost to the primary tumor site (n = 40) or the tumor region only (n = 13). No radiotherapy was administered in two patients. Results: Median follow-up was 38 months. The overall survival rate at 3 years after surgery was 75.6%. Disease progression occurred in 25 children with local progression occurring in 20. The median time to disease progression was 45 months. The only significant prognostic factor was the extent of resection (estimated progression-free survival [EPFS] after 3 years was 83.3% after complete resection and 38.5% after incomplete resection) and the presence of metastases at the time of diagnosis (0% vs. 65.8% 3-year EPFS in localized tumors). Age, sex, tumor site, mode of chemotherapy, and irradiation volume did not influence survival. Conclusions: Treatment centers should be meticulous about surgery and diagnostic workup. Because the primary tumor region is the predominant site of failure it is important to intensify local treatment. Dose escalation by hyperfractionation or stereotactic radiotherapy might be a promising approach in macroscopically residual disease. The role of adjuvant chemotherapy requires further study

    Active oncotherapy, combination chemotherapy of lung cancer is accompanied with many side effects which may impair patients' quality of life and compromise the effectiveness of chemotherapy. Most side effects of chemotherapy are preventable or treatable with optimal supportive care which enhances success in patient care and treatment. The aim of this review is to summarize the most important conditions that may be associated with combined chemotherapy of lung cancer from the practical point of view.

    We analyzed the treatment responses, toxicities, and survival outcomes of patients with relapsed or refractory multiple myeloma who received daily thalidomide, cyclophosphamide, and dexamethasone (CTD) or daily thalidomide, melphalan, and prednisolone (MTP) at 17 medical centers in Korea. Three-hundred and seventy-six patients were enrolled. The combined chemotherapy of thalidomide, corticosteroid, and an alkylating agent (TAS) was second-line chemotherapy in 142 (37.8%) patients, and third-line chemotherapy in 135 (35.9%) patients. The response rate overall was 69.4%. Patients who were not treated with bortezomib and lenalidomide before TAS showed a higher response rate compared to those who were exposed to these agents. The estimated median progression-free survival and overall survival times were 10.4 months and 28.0 months, respectively. The adverse events during TAS were generally tolerable, but 39 (10.4%) patients experienced severe infectious complications. There were no differences in terms of efficacy between CTD and MTP, but infectious complications were more common in CTD group. TAS is an effective treatment regimen which induces a high response rate in relapsed or refractory multiple myeloma patients. Due to the high incidence of grade 3 or 4 infection, proper management of infection is necessary during the TAS treatment, especially the CTD. © 2016 The Authors.

    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.

    Since 1982, we have performed 125 courses of CHOP chemotherapy for 27 patients of malignancy, adhering to the original regimen as strictly as possible. CHOP chemotherapy consisted of Cyclophosphamide 750 mg/m 2 , iv, on day 1; Adriamycin 50 mg/m 2 , iv, on day 1; Vincristine 1.4 mg/m 2 , iv, on day 1 (maximum single dose 2.0 mg) and Prednisolone 50 mg/m 2 , po, day 1 through 5. The cycle was repeated every 21 days. As side effects, myelosuppression, hair loss, fever, nausea, vomiting, liver dysfunction, stomatitis, neuropathy, herpes zoster, arrhythmia and hemorrhagic cystitis were seen. Due to myelosuppression, twenty patients experienced febrile episodes at each nadir of WBC counts on 40 courses. However, any febrile patient did not have life threatening infection. Other side effects were also reversible. The radiotherapy of most patients was carried out as initially scheduled, except for 3 patients in whom irradiation was interrupted due to severe stomatitis or herpes zoster. We consider that CHOP chemotherapy is excellent in feasibility even when combined with radiotherapy. (author)

Therefore, combinational therapy based on chemotherapy mediated by nanotechnology, has been the trend in clinical research at present, which can result in a remarkably increased therapeutic efficiency with few side effects to normal tissues. Moreover, to achieve the accurate pre-diagnosis and real-time monitoring for tumor, the research of nano-theranostics, which integrates diagnosis with treatment process, is a promising field in cancer treatment. In this review, the recent studies on combinational therapy based on chemotherapy will be systematically discussed. Furthermore, as a current trend in cancer treatment, advance in theranostic nanoparticles based on chemotherapy will be exemplified briefly. Finally, the present challenges and improvement tips will be presented in combination therapy and nano-theranostics.

  5. Adjuvant chemotherapy for osteosarcoma.

    From this review of chemotherapy trials, several observations can be made. Osteosarcoma is a complex disease involving multiple histologies, each with a different prognosis. Prognostic factors that have been shown to be important include anatomic location of the primary tumor, stage at presentation (patients with metastatic or local recurrent disease fair far worse than those with primary disease), age at onset (children fair worse than the teenager with osteosarcoma), and location within the extremity (patients with more distal tumors fairing better than patients with more proximal tumors). There is convincing evidence for the efficacy of chemotherapeutic agents such as methotrexate in high doses (at least 8 g/m2 for adults, 12 g/m2 for children), Adriamycin, and cisplatin. The combination of Adriamycin and cisplatin appears to be more beneficial relative to either one of these agents alone. The efficacy of the combination of BCD as a triple-drug regimen, although useful in several different trials, has not been convincingly shown. Finally, from several of the recent randomized trials, it appears, that chemotherapeutic regimens containing an Adriamycin and cisplatin combination appear to be superior to those that do not include this combination. However, these observations are made from a historical perspective and have not been conclusively proven by randomized prospective investigations. The observations concerning the natural history of the disease and the activity of various chemotherapeutic agents suggest certain clinical practice algorithms. Essential staging procedures would include a bone scan looking for multifocal or metastatic disease, and CT scans of the chest looking for metastases to the lung. From all studies, it is apparent that surgery is mandatory for the primary tumor and should be an integral portion of all treatment methods. Chemotherapy should be considered for all patients with osteosarcoma, and the essential drugs in the regimen appear at

    Most malaria control strategies today depend on safe and effective drugs, as they have done for decades. But sensitivity to chloroquine, hitherto the workhorse of malaria chemotherapy, has rapidly declined throughout the tropics since the 1980s, and this drug is now useless in many high-transmission areas. New options for resource-constrained governments are few, and there is growing evidence that the burden from malaria has been increasing, as has malaria mortality in Africa. In this chapter, we have tried to outline the main pharmacological properties of current drugs, and their therapeutic uses and limitations. We have summarised the ways in which these drugs are employed, both in the formal health sector and in self-medication. We have briefly touched on the limitations of current drug development, but have tried to pick out a few promising drugs that are under development. Given that Plasmodium falciparum is the organism that kills, and that has developed multi-drug resistance, we have tended to focus upon it. Similarly, given that around 90% of global mortality from malaria occurs in Africa, there is the tendency to dwell on this continent. We give no apology for placing our emphasis upon the use of antimalarial drugs in endemic populations rather than their use for prophylaxis in travellers.

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies

    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/m 2 /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

    We have begun to apply arterial redistribution and preoperative embolization in superselective intra-arterial chemotherapy from the superficial temporal artery. This study examines two typical cases of upper gingival cancer. Case 1 was a male, age 61, with T4N0M0 upper gingival cancer. Drug dosage began with 50-100 mg/m 2 /day of 5-fluorouracil (FU), while 15 mg/m 2 /hour of Docetaxel was also given once a week for three weeks. At the same time, radiation therapy with a total of 30 Gy (2 Gy at a time) was given. Immediately before the operation, embolization in the internal maxillary artery was performed in order to limit bleeding. Case 2 was a female, age 73, with T3N0M0 upper gingival cancer. This patient was also given 5-FU and Docetaxel for four weeks respectively with a total of 40 Gy radiation therapy. No operation was performed. Both cases gained complete response (CR) with a sole side effect of grade 3 mucositis. Superselective intra-arterial chemotherapy with arterial redistribution in the oral area is highly effective due to local, concentrated dosage of anticancer drug and reduced side effects. It is a promising method to replace surgical operation especially in cases of upper gingival cancer, whose tumor is often limited to the internal maxillary artery alone. (author)

In this study, we designed a simple but effective nanoparticle system for carrying IR780 and paclitaxel, thus hoping to combine PTT/PDT and chemotherapy to treat hepatocellular carcinoma (HCC. This nanosystem, named PDF nanoparticles, consisted of phospholipid/Pluronic F68 complex nanocores and pullulan shells. IR780 and paclitaxel were loaded separately into PDF nanoparticles to form PDFI and PDFP nanoparticles, which had regular sphere shapes and relatively small sizes. Upon near-infrared laser irradiation at 808 nm, PDFI nanoparticles showed strong PTT/PDT efficacy both in vitro and in vivo. In MHCC-97H cells, the combined treatment of PDFI nanoparticles/laser irradiation and PDFP nanoparticles exhibited significant synergistic effects on inhibiting cell proliferation and inducing cell apoptosis and cell cycle arrest at G2/M phase. In MHCC-97H tumor-bearing mice, PDFI nanoparticles exhibited excellent HCC-targeting and accumulating capability after intravenous injection. Furthermore, the combined treatment of PDFI nanoparticles/laser irradiation and PDFP nanoparticles also effectively inhibited the tumor growth and the tumor angiogenesis in MHCC-97H tumor-bearing mice. In summary, we put forward a therapeutic

    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).

    Tigatuzumab is the humanized version of the agonistic murine monoclonal antibody TRA-8 that binds to the death receptor 5 and induces apoptosis of human cancer cell lines via the caspase cascade. The combination of tigatuzumab and gemcitabine inhibits tumor growth in murine pancreatic xenografts. This phase 2 trial evaluated the efficacy of tigatuzumab combined with gemcitabine in 62 chemotherapy-naive patients with histologically or cytologically confirmed unresectable or metastatic pancreatic cancer. Patients received intravenous tigatuzumab (8 mg/kg loading dose followed by 3 mg/kg weekly) and gemcitabine (1000 mg/m 2 once weekly for 3 weeks followed by 1 week of rest) until progressive disease (PD) or unacceptable toxicity occurred. The primary end point was progression-free survival (PFS) at 16 weeks. Secondary end points included objective response rate (ORR) (complete responses plus partial responses), duration of response, and overall survival (OS). Safety of the combination was also evaluated. Mean duration of treatment was 18.48 weeks for tigatuzumab and 17.73 weeks for gemcitabine. The PFS rate at 16 weeks was 52.5% (95% confidence interval [CI], 39.3–64.1%). The ORR was 13.1%; 28 (45.9%) patients had stable disease and 14 (23%) patients had PD. Median PFS was 3.9 months (95% CI, 2.2–5.4 months). Median OS was 8.2 months (95% CI, 5.1–9.6 months). The most common adverse events related to tigatuzumab were nausea (35.5%), fatigue (32.3%), and peripheral edema (19.4%). Tigatuzumab combined with gemcitabine was well tolerated and may be clinically active for the treatment of chemotherapy-naive patients with unresectable or metastatic pancreatic cancer

    We analyzed the responses to first line treatment and clinical outcomes of metastatic breast cancer patients treated with palliative doxorubicin/cyclophosphamide (AC) according to molecular cancer subtype. A retrospective analysis was performed for 110 metastatic breast cancer patients selected on the basis of palliative AC treatment and the availability of immunohistochemical data for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER-2/neu) status. Of the 110 patients analyzed, 71 (64.5%) were hormone receptor positive (HR+), 14 (12.7%) were HER2+, and 25 (22.7%) were triple negative (TN). There were no differences in age, stage at diagnosis, total number of cycles of palliative chemotherapy, incidence of visceral metastasis, and metastatic sites with the exception of liver among breast cancer subtypes. The overall response rates to AC were 55.9% for the HR+ subgroup, 42.9% for the HER2+ subgroup, and 56.5% for the TN subgroup. The progression-free survival (PFS) in patients with HER2+ and TN were significantly shorter than in the HR+ (median PFS, 9.1 vs 8.1 vs 11.5 months, respectively; p = 0.0002). The overall survival (OS) was 25.4 months in the TN subgroup and 27.3 months in HER2+ subgroup. The median OS for these two groups was significantly shorter than for patients in the HR+ subgroup (median, 38.5 months; 95% CI, 30.1-46.9 months; p < 0.0001). The response to palliative AC chemotherapy did not differ among breast cancer subtypes. Despite chemosensitivity for palliative AC, the TN subtype has a shorter overall survival than non-TN subtypes. Innovative treatment strategies should be developed to slow the course of disease

    The authors evaluated 83 patients with ovarian cancer who were irradiated or treated by a combination of cytoxan, adriamycin, and cisplatin. According to FIGO stage, eight patients had stage I disease, 12 had stage II disease, 61 had stage II disease and two has stage IV disease. Fifty patients had bulky disease and 33 had minimal disease of 2 cm or less. Sixty patients were irradiated to an open abdominopelvic field (30 Gy delivered over 4 weeks), with or without a pelvic boost. Fifty-five patients received combination chemotherapy and 30 received a single agent as initial therapy. The patients were divided into three groups. The 26 patients in group I received primary radiation therapy with or with out adjuvant single-agent chemotherapy, then combination chemotherapy to salvage. The 34 patients in group II were irradiated after chemotherapy, mainly combination chemotherapy, failed. The 23 patients in group III received, mainly combination chemotherapy with second-line drugs for salvage

    We present a pooled analysis of predictive and prognostic values of circulating tumour cells (CTC) and circulating endothelial cells (CEC) in two prospective trials of patients with inflammatory breast cancer (IBC) treated with neoadjuvant chemotherapy combined with neoadjuvant and adjuvant bevacizumab. Nonmetastatic T4d patients were enrolled in two phase II multicentre trials, evaluating bevacizumab in combination with sequential neoadjuvant chemotherapy of four cycles of FEC followed by four cycles of docetaxel in HER2-negative tumour (BEVERLY-1) or docetaxel and trastuzumab in HER2-positive tumour (BEVERLY-2). CTC and CEC were detected in 7.5 and 4 ml of blood, respectively, with the CellSearch System. From October 2008 to September 2010, 152 patients were included and 137 were evaluable for CTC and CEC. At baseline, 55 patients had detectable CTC (39%). After four cycles of chemotherapy, a dramatic drop in CTC to a rate of 9% was observed (P < 0.01). Pathological complete response (pCR) rate was 40%. No correlation was found between CTC or CEC levels and pCR rate. Median follow-up was 43 months. CTC detection (≥1 CTC/7.5 ml) at baseline was associated with shorter 3-year disease-free survival (39% versus 70% for patients without CTC, P < 0.01, HR 2.80) and shorter 3-year overall survival (OS) (P < 0.01). In multivariate analysis, independent prognostic parameters for shorter survival were absence of hormonal receptors, no pCR and CTC detection at baseline. CEC level at baseline or variations during treatment had no prognostic value. In this pooled analysis of two prospective trials in nonmetastatic IBC, detection rate of CTC was 39% with a strong and independent prognostic value for survival. Combination of pCR after neoadjuvant treatment with no CTC detection at baseline isolated a subgroup of IBC with excellent OS (94% 3-year OS), suggesting that CTC count could be part of IBC stratification in prospective trials. © The Author 2016

    Forty-three ambulatory patients with locally advanced or metastatic bronchogenic adenocarcinoma were sequentially treated with two potentially mutually non-cross-resistant chemotherapy regimens. A new regimen, MVPF (mitomycin-c, vinblastine, procarbazine, and 5-fluorouracil), was given until progressive disease occurred. Then, a second regimen--MOCC (methotrexate, vincristine [Oncovin], cyclophosphamide, and CCNU)--was initiated. At further progression, regional disease patients received radiotherapy, whereas extensive disease patients received Phase II agents. Of the 43 patients entered on the study, 40 were evaluable. Three patients withdrew early due to poor tolerance of the regimen. The response rate for MVPF was 33% (12 of 40 PR, 1 of 40 CR) compared to a 4% (1 of 23 PR) response for MOCC (difference: p < or = .03), for a total response rate of 35%. Although there was an initial improvement in survival for responders (31.7 weeks) versus nonresponders (15.7 weeks) at the 75th percentile (p < or = .05), there was no significant difference in median survival. The hematologic toxicity was equivalent for both groups, whereas nonhematologic toxicity revealed a high incidence of nausea and vomiting in the MVPF group. It is concluded that this approach lent itself well to ambulatory care, and MVPF could be considered an alternative to cyclophosphamide-based regimens. However, the absence of a meaningful CR rate and lack of influence of response on median survival were factors limiting its effectiveness.

    Fifty-one patients with non-Hodgkin's lymphoma refractory or relapsing after CHOP-like regimen, underwent a salvage chemotherapy by VPH: etoposide 100 mg/m2/d, D1 to D3, cisplatin 20 mg/m2/d, D1 to D5, ifosfamide 1 g/m2/d D1 to D5, mesna 1.2 g/m2/d D1 to D5, every 4 weeks. Among 46 evaluable patients for efficacy, 21 (45.6%) achieved complete or partial response according to WHO criteria and 25 (54.3%) failed, while five cases (9.8% of all patients) were not evaluable (two initial complete remission before VPH, two early toxic deaths and one confusional syndrome). Thirty-five patients (68.6%) died of lymphoma, three (5.8%) of acute toxicity and 13 (25.5%) are alive: five in complete remission. The toxicity is mainly myelo-suppression, digestive and renal but could be managed as usually. Although the follow-up is short, this regimen appears effective in these circumstances after CHOP failure but it should be used early, before overt chemoresistance. It does not hinder a bone marrow transplantation programme.

    Objective: To investigate the change of breast cancer patients' electrocardiogram during combined radiotherapy and chemotherapy or chemotherapy alone for the sake of predicting the cardiotoxicity of combined radiotherapy and chemotherapy. Methods: From January, 1998 to June, 2004, 47 postoperative breast cancer patients were enrolled. Among them 29 patients received chemotherapy combined with radiotherapy (combinative group), and 18 patients received chemotherapy alone (non combinative group). The changes of electrocardiogram were observed and correlation factors were analyzed. Results: Abnormal electrocardiograms were noted in 11 (37.9%) and 2 patients (11.1%) of the combinative group and the non-combinative group respectively(z=-1.977, P=0.048). In the combinative group, heart events were significantly increased in patients above 60 years old (z=- 2.094 P=0.036). The changes of electrocardiogram were not significantly correlative with hypertension history, tumor site, dose of radiotherapy or chemotherapeutic drugs. But the incidence of abnormal electrocardiogram was higher in patients with a hypertension history than in those without it (54.5% vs 27.8%). Conclusion: The abnormalities of electrocardiogram were are more frequent in patients treated with both radiotherapy combined with chemotherapy. Our results suggest that breast cancer patients should be regularly reexamined with electrocardiography during therapy, especially whose age was those have a hypertension history and above 60 years old.

    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

    18 F-FDG PET/CT is potentially applicable to predict response to chemotherapy in combination with bevacizumab in patients with advanced non-small cell lung cancer (NSCLC). Methods: In 25 patients with advanced nonsquamous NSCLC, 18 F-FDG PET/CT was performed before treatment and after 2 wk, at the end of the second week of first cycle carboplatin-paclitaxel and bevacizumab (CPB) treatment. Patients received up to a total of 4 cycles of CPB treatment. Maintenance treatment with bevacizumab monotherapy was continued until progressive disease without significant treatment-related toxicities of first-line treatment. In the case of progressive disease, bevacizumab was combined with erlotinib. SUV corrected for lean body mass (SUL and SUL peak ) were obtained. PERCIST were used for response evaluation. These semiquantitative parameters were correlated with progression-free survival and overall survival (OS). Results: Metabolic response, defined by a significant reduction in SUL peak of 30% or more after 2 wk of CPB, was predictive of progression-free survival and OS. For partial metabolic responders ( n = 19), the median OS was 22.8 mo. One-year and 2-y OS were 79% and 47%, respectively. Nonmetabolic responders ( n = 6) (stable metabolic disease or progressive disease) showed a median OS of 4.4 mo (1-y and 2-y OS was 33% and 0%, respectively) ( P predictive of outcome to first-line chemotherapy with bevacizumab in patients with advanced nonsquamous NSCLC. This enables identification of patients at risk of treatment failure, permitting treatment alternatives such as early switch to a different therapy. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. To assess the efficacy of chemotherapy versus best supportive care (BSC), combination versus single-agent chemotherapy and different chemotherapy combinations in advanced gastric cancer. We searched the Cochrane Central Register of Controlled Trials, MEDLINE and Embase up to June 2016, reference lists of studies, and contacted pharmaceutical companies and experts to identify randomised controlled trials (RCTs). We considered only RCTs on systemic, intravenous or oral chemotherapy versus BSC, combination versus single-agent chemotherapy and different chemotherapy regimens in advanced gastric cancer. Two review authors independently identified studies and extracted data. A third investigator was consulted in case of disagreements. We contacted study authors to obtain missing information. We included 64 RCTs, of which 60 RCTs (11,698 participants) provided data for the meta-analysis of overall survival. We found chemotherapy extends overall survival (OS) by approximately 6.7 months more than BSC (hazard ratio (HR) 0.3, 95% confidence intervals (CI) 0.24 to 0.55, 184 participants, three studies, moderate-quality evidence). Combination chemotherapy extends OS slightly (by an additional month) versus single-agent chemotherapy (HR 0.84, 95% CI 0.79 to 0.89, 4447 participants, 23 studies, moderate-quality evidence), which is

    Purpose/Objective: The role of chemotherapy in the management of squamous cell carcinoma of the upper aerodigestive tract is undergoing rapid evolution. Historically, the use of chemotherapy was limited to patients with incurable disease who had exhausted all surgical and radiation therapy options. The results of recent randomized trials, however, suggest an increasing role for chemotherapy as part of primary management in patients with unresectable disease; advanced larynx or hypopharynx cancer with the intent of larynx preservation, or advanced nasopharynx cancer. This refresher course will provide a comprehensive overview of the current indications for chemotherapy in the management of these malignancies, and will highlight areas of controversy and future directions of investigation. More specifically, the following areas will be emphasized. 1. The identification of drugs commonly used in the management of head and neck cancer, their customary dosing and side effects. 2. The impact of induction and/or adjuvant chemotherapy combined with surgery and radiation therapy as defined by randomized trials, including a discussion of the Head and Neck Contracts program and the Intergroup adjuvant trial. 3. The development of larynx/function preservation treatment programs, including a review of the Veterans Administration and EORTC larynx preservation studies. 4. The evolving role of chemotherapy as part of innovative combined modality programs, especially in patients with unresectable disease. The rationale and utility of sequential versus concomitant/alternating chemotherapy-radiation strategies, and relevant randomized clinical trials comparing the different strategies will be discussed. 5. The appropriate application of chemotherapy in the palliative setting, including a discussion of the relative merits of single-agent versus combination chemotherapy

    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

    AXP107-11 is a novel, multi-component crystalline form of the naturally occurring compound genistein. AXP107-11 has improved physiochemical properties and oral bioavailability compared to the natural form of genistein, and it is possible that combining AXP107-11 with chemotherapy may increase the effect and reduce chemoresistance. The purpose of this dose escalation phase Ib study was to assess the safety, maximum tolerated dose (MTD) and pharmacokinetics (PK) of AXP107-11 in combination with gemcitabine in treatment-naïve patients with inoperable pancreatic carcinoma. AXP107-11 was given orally in escalating doses (400 mg-1600 mg daily) in combination with standard gemcitabine treatment (1000 mg/m(2)/week) for the first seven of eight weeks and thereafter for a maximum of four × four-week treatment cycles. PK, safety, MTD and efficacy of AXP107-11 in combination with gemcitabine were evaluated. Sixteen patients were enrolled and received AXP107-11. The maximum concentration in serum of unconjugated (free) genistein was 1 μM. Neither dose-limiting toxicities (DLTs) nor signs of hematological or non-hematological toxicities related to AXP107-11 were observed over a period ranging from 0.7 to 13.2 months. The median overall survival time was 4.9 months (range 1.5-19.5 months). Seven patients (44%) survived longer than six months and 19% were alive at the one-year follow-up. Treatment of pancreatic cancer patients with AXP107-11 in combination with gemcitabine resulted in a favorable PK-profile with high serum levels without signs of either hematological or non-hematological toxicity. Accordingly, we suggest further studies with AXP107-11 in pancreatic cancer patients. Copyright © 2016 IAP and EPC. Published by Elsevier B.V. All rights reserved.

    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.

    Adenocarcinomas of esophagus and cardia represent in France approximately 20 to 40% of the esophagus cancers. They have a high risk to develop lymph nodes metastases and liver metastases. Currently, only 50 to 70% of patients may benefit from surgical curative resection at diagnosis, but more than 50% of them will recur. The standard of treatment of these metastatic adenocarcinomas is chemotherapy. Three large randomized comparative studies, between chemotherapy and supportive care, showed that chemotherapy significantly extends the median of survival (from 3-4 months to 10-12 months) and improves the quality of life. Currently, the combination of epirubicin-cisplatin-continuous 5FU (ECF) is the most effective regimen but it is difficult to administer and tolerate because of the long continuous 5FU infusion. In France, the most commonly used combination regimen still associates 5FU and cisplatin. New drugs (such as docetaxel, CPT11, oxaliplatin) used alone or in combination, especially with 5U, are very promising. Radio-chemotherapy is the preferred treatment for locoregional recurrences, because it improves dysphagia and enables to obtain complete tumor responses. Current results from concomitant radio-chemotherapy studies for esophagus cancer, based on 5FU alone, 5FU-cisplatin or 5FU-mitomycin, given as preoperative treatment or as exclusive treatment, support to use radio-chemotherapy for the treatment of loco-regional recurrences after surgical resection. Nevertheless, the optimal radio-chemotherapy schedule still remain to be defined (dose, duration, splitting of radiotherapy, choice of anticancer drugs). (authors)

  15. Utilization of a selective tumour artery catheterization technique for the intra-arterial delivery of chemotherapeutic agents and radiopharmaceuticals in a combined chemotherapy-radiotherapy clinical research programme

    Combined intra-arterial chemotherapeutic agents (principally actinomycin-D) and radiation therapy has been utilized in the treatment of 35 patients with massive unresectable malignancies. The goals may be separated into three distinct categories. An attempt has been made to convert unresectable malignancies to surgical resectability, to provide a definitive therapy for massive tumours in patients who either refuse surgery or are not surgery candidates, and to provide palliation. Twelve of 15 initially unresectable tumours treated with actinomycin-D became surgically resectable (no resection was attempted in the other four because they either developed metastasis during therapy or did not complete the therapy), 4 of 6 massive tumours treated definitively have remained locally controlled from 18 to 108 months, and 7 of 9 patients treated palliatively were significantly benefited by the therapy. Impressive responses were also achieved in several patients treated with intra-arterial 5-fluorouracil and 5-iodo-2'-deoxyuridine. The authors therefore consider combined, concurrent radiation therapy and intra-arterially administered chemotherapeutic agents worthy of further clinical investigation as a means of treating massive malignancies. They also suggest that the best chance of optimizing the therapeutic ratio of such therapy is dependent primarily on a proper understanding of clinical tumour vascularity and of its subsequent effect on drug and oxygen distributions within the radiation treatment volume. Accordingly, tumour vascularity has been clinically evaluated by the use of intra-arterially administered radiopharmaceuticals. Such clinical data, in conjunction with radiobiological data, might in the future be utilized to optimize both low and high LET combined therapy by allowing for correction of the physical isodose for drug and oxygen concentration variations.

    Full Text Available After failure of anthracycline- and platinum-based therapy, no effective therapies exist for management of metastatic triple-negative breast cancer (TNBC. We report a case of metastatic TNBC harboring MCL1 amplification, as identified by comprehensive genomic profiling in the course of clinical care. MCL1 is an antiapoptotic gene in the BCL2 family, and MCL1 amplification is common in TNBC (at least 20%. A personalized dose-reduced regimen centered on a combination of sorafenib and vorinostat was implemented, based on preclinical evidence demonstrating treatment synergy in the setting of MCL1 amplification. Although hospice care was being considered before treatment initiation, the personalized regimen yielded 6 additional months of life for this patient. Further rigorous studies are needed to confirm that this regimen or derivatives thereof can benefit the MCL1-amplified subset of TNBC patients.

    A phase I trial of first-line vorinostat, an orally bio-available histone deacetylase inhibitor, in combination with capecitabine plus cisplatin (XP) was performed to assess recommend phase II trial dose in patients with advanced gastric cancer. Five dose levels of three-weekly vorinostat-XP were tested; vorinostat was dosed at 300-400 mg once daily on Days 1-14, capecitabine at 800-1,000 mg/m(2) twice daily on Days 1-14, and cisplatin at 60-80 mg/m(2) on Day 1. To assess the pharmacodynamics of vorinostat, histone H3 acetylation was assessed in peripheral blood mononuclear cells before the study treatment and at Day 8 of cycle 1. In total, 30 patients with unresectable or metastatic gastric adenocarcinoma were included. Dose-limiting toxicities were thrombocytopenia, fatigue, stomatitis, and anorexia. The following doses were recommended for phase II trial: 400 mg of vorinostat once daily, 1,000 mg/m(2) of capecitabine twice daily, and 60 mg/m(2) of cisplatin. The most common grade 3-4 toxicities were neutropenia (47 %), anorexia (20 %), thrombocytopenia (17 %), and fatigue (13 %). In overall, response rate was 56 % (95 % confidence interval [CI]: 32-81). With a median follow-up of 14.1 months, the median progression-free survival and overall survival were 7.1 months (95 % CI: 3.8-10.3) and 18.0 months (95 % CI: 4.8-31.1), respectively. The change in H3 acetylation after treatment with vorinostat correlated significantly with the vorinostat dose (300 vs. 400 mg/day) and the baseline level of H3 acetylation before treatment. Three-weekly vorinostat-XP regimen is feasible and recommended for further development in advanced gastric cancer.

    To improve the complete remission (CR) rate of newly diagnosed acute myeloid leukemia (AML) patients and alleviate the severe side effects of double induction chemotherapy, we combined a standard regimen with granulocyte colony-stimulating factor (G-CSF) priming chemotherapy to compose a new double induction regimen for AML patients who failed to achieve CR after the first course. Ninety-seven patients with AML who did not achieve CR after the first course of standard chemotherapy were enrolled. Among them, 45 patients received G-CSF priming combined with low-dose chemotherapy during days 20-22 of the first course of chemotherapy, serving as priming group, 52 patients were administered standard chemotherapy again, serving as control group. Between the two groups there were no differences in the French-American-British (FAB) classification, risk status, the first course of chemotherapy, blood cell count or blasts percentage of bone marrow before the second course. But the CR rate was significantly higher and the adverse effect was much lower in the priming group than the control group. Cox multivariate regression analysis showed that WBC level before the second course and the selection of the second chemotherapy regimen were two independent factors for long survival of patients. These results elucidate that standard chemotherapy followed by G-CSF priming new double induction chemotherapy is an effective method for AML patients to improve CR rate and reduce adverse effects.

    Pre-operative chemoradiotherapy using a 5-fluorouracil (5-FU)/cisplatin backbone is widely used to improve surgical outcomes in locoregional oesophageal cancer patients, despite a non-negligible failure rate. We evaluated intensification of this approach to improve patient outcomes by adding cetuximab to induction 5-FU/cisplatin/docetaxel (TPF) and to chemoradiotherapy in a phase II study. Between November 2006 and April 2009, 50 patients with stage II-IVa squamous cell carcinoma (SCC) or adenocarcinoma of the oesophagus or gastro-oesophageal junction initiated three TPF/cetuximab cycles. Six weeks later, patients with response or stabilisation initiated 6 weeks of cisplatin/cetuximab/radiotherapy, followed by surgery. The primary objective was the clinical complete response (cCR) rate after induction therapy plus chemoradiotherapy in intent-to-treat patients. Thirty-eight patients were evaluable after chemoradiotherapy, 84% of whom showed disease control. Six patients (12%) achieved a cCR, with a 54% overall response rate. Twenty-seven patients underwent surgery, 11 of whom (22%; nine SCC, two adenocarcinoma) had a pathological CR (41%). Fifteen patients were alive after a median follow-up of 23.2 months. Median progression-free survival was 12.2 months (95% confidence interval [CI] 1.7-22.8). Median overall survival was 23.4 months (95% CI 12.2-36.6) and was significantly longer among the 22 patients with complete resection than in the five patients without (42.1 vs. 24.9 months; p = 0.02, hazard ratio: 3.6, 95% CI 1.1-11.6). The toxicity profile was acceptable. Neoadjuvant cetuximab/TPF followed by chemoradiotherapy in locoregional oesophageal carcinoma patients is feasible and offers a modest response rate in this trial. The results of combining trimodality neoadjuvant treatment with cetuximab are consistent with the literature. Registration: The study is registered at ClinicalTrials.gov (NCT00733889).

  4. Cancer occurring after radiotherapy and chemotherapy

    Radiotherapy and chemotherapy can effectively control cancer but can also cause new cancers to develop as long-term complications. Almost all types of cancer have been associated with radiotherapy. The breast, thyroid, and bone marrow are the organs most susceptible to radiation carcinogenesis. The bone marrow is also most frequently involved by chemotherapy and the leukemia risk is much higher than after radiotherapy. The combination of intensive radiotherapy and chemotherapy is particularly leukemogenic. The latent period between radiotherapy/chemotherapy and the appearance of a second primary cancer ranges from a few years to several decades. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments. This is particularly the case in individuals with long life expectancy, for example, patients treated for childhood neoplasms. The benefits of radiotherapy and chemotherapy in oncology exceed the risks for second primary cancers. Efforts should be directed towards identifying those patients who will benefit from the treatments so that only they are exposed to the risk. 33 references

    Full Text Available Abstract Background Pancreatic cancer is the fourth commonest cause of death from cancer in men and women. Advantages in surgical techniques, radiation therapy techniques, chemotherapeutic regimes, and different combined-modality approaches have yielded only a modest impact on the prognosis of patients with pancreatic cancer. Thus there is clearly a need for additional strategies. One approach involves using the identification of a number of molecular targets that may be responsible for the resistance of cancer cells to radiation or to other cytotoxic agents. As such, these molecular determinants may serve as targets for augmentation of the radiotherapy or chemotherapy response. Of these, the epidermal growth factor receptor (EGFR has been a molecular target of considerable interest and investigation, and there has been a tremendous surge of interest in pursuing targeted therapy of cancers via inhibition of the EGFR. Methods/design The PARC study is designed as an open, controlled, prospective, randomized phase II trial. Patients in study arm A will be treated with chemoradiation using intensity modulated radiation therapy (IMRT combined with gemcitabine and simultaneous cetuximab infusions. After chemoradiation the patients receive gemcitabine infusions weekly over 4 weeks. Patients in study arm B will be treated with chemoradiation using intensity modulated radiation therapy (IMRT combined with gemcitabine and simultaneous cetuximab infusions. After chemoradiation the patients receive gemcitabine weekly over 4 weeks and cetuximab infusions over 12 weeks. A total of 66 patients with locally advanced adenocarcinoma of the pancreas will be enrolled. An interim analysis for patient safety reasons will be done one year after start of recruitment. Evaluation of the primary endpoint will be performed two years after the last patient's enrolment. Discussion The primary objective of this study is to evaluate the feasibility and the toxicity profile of

    2015-05-01

    Although cancer chemotherapy has historically been considered immune suppressive, it is now accepted that certain chemotherapies can augment tumor immunity. The recent success of immune checkpoint inhibitors has renewed interest in immunotherapies, and in combining them with chemotherapy to achieve additive or synergistic clinical activity. Two major ways that chemotherapy promotes tumor immunity are by inducing immunogenic cell death as part of its intended therapeutic effect and by disrupting strategies that tumors use to evade immune recognition. This second strategy, in particular, is dependent on the drug, its dose, and the schedule of chemotherapy administration in relation to antigen exposure or release. In this Cancer Immunology at the Crossroads article, we focus on cancer vaccines and immune checkpoint blockade as a forum for reviewing preclinical and clinical data demonstrating the interplay between immunotherapy and chemotherapy. ©2015 American Association for Cancer Research.

    Basing on a collective statistic of 123 cases of plasmocytoma in the University Radiation Clinic of Heidelberg, the radio- and chemo-therapeutical points of view of the reasonable treatment direction are outlined, taking radiological and protein-chemical findings as suitable course criteria. The results which can be obtained therapeutically are temporally restricted, especially in progressed stages of the disease, but they can be improved by individually adjusted treatment coordination. The radiation therapy can be efficiently applied to ease the pain and to support recalcification. In addition to the disease-specific treatment, the prophylaxis and therapy of the plasmo-cytoma-complications is of great importance. First interesting beginnings of the treatment are seen in the sensibilisation test of the myeloma tissue for increasing the therapeutical efficiency. The success of the therapy depends on the date of the diagnosis. (orig.) 891 MG/orig. 892 RDG [de

    Currently, prediction of survival for non-small-cell lung cancer patients treated with (chemo)radiotherapy is mainly based on clinical factors. The hypothesis of this prospective study was that blood biomarkers related to hypoxia, inflammation, and tumor load would have an added prognostic value for predicting survival. Clinical data and blood samples were collected prospectively (NCT00181519, NCT00573040, and NCT00572325) from 106 inoperable non-small-cell lung cancer patients (Stages I-IIIB), treated with curative intent with radiotherapy alone or combined with chemotherapy. Blood biomarkers, including lactate dehydrogenase, C-reactive protein, osteopontin, carbonic anhydrase IX, interleukin (IL) 6, IL-8, carcinoembryonic antigen (CEA), and cytokeratin fragment 21-1, were measured. A multivariate model, built on a large patient population (N = 322) and externally validated, was used as a baseline model. An extended model was created by selecting additional biomarkers. The model's performance was expressed as the area under the curve (AUC) of the receiver operating characteristic and assessed by use of leave-one-out cross validation as well as a validation cohort (n = 52). The baseline model consisted of gender, World Health Organization performance status, forced expiratory volume, number of positive lymph node stations, and gross tumor volume and yielded an AUC of 0.72. The extended model included two additional blood biomarkers (CEA and IL-6) and resulted in a leave-one-out AUC of 0.81. The performance of the extended model was significantly better than the clinical model (p = 0.004). The AUC on the validation cohort was 0.66 and 0.76, respectively. The performance of the prognostic model for survival improved markedly by adding two blood biomarkers: CEA and IL-6. Copyright © 2011 Elsevier Inc. All rights reserved.

    Acute leukemia and lymphoma varieties of adult T-cell leukemia/lymphoma (ATL) usually carry a poor prognosis. While etoposide is generally useful for treating ATL, especially as a daily oral maintenance regimen, etoposide has not proven effective in severe types of ATL efficient in some patients. Of 87 ATL patients whom we have treated, 51 had acute leukemia, 22 lymphoma and 14 progressive chronic leukemia. Seventy-nine patients were treated with a long term maintenance combination protocol, OPEC/MPEC (weekly doses of vincristine, 0.7 mg/m2 or methotrexate, 14 mg/m2; prednisolone, 20 mg/m2; etoposide, 70 mg/m2 and cyclophosphamide, 200 mg/m2). The other 8 patients, 3 with acute leukemia, 2 with lymphoma and 3 with progressive chronic leukemia, were treated with daily oral administration of 25 mg of etoposide and 10 mg of prednisolone (DOEP). The dose administered was modified in individual cases to maintain the granulocyte count and reduce the number of ATL cells. Considering both protocols, a complete response and a partial response were achieved in 31.0% and 58.6% patients, respectively. Median survival times (MST) of all patients and, acute leukemia, lymphoma and progressive chronic leukemia types were 7.5, 6.7, 9.6 and 12.4 months, respectively. Respective MST of patients treated with OPEC/MPEC or DOEP protocols were 7.1 and 18.0 months. Relatively normal WBC counts, lower lactate dehydrogenase concentration and normal calcium concentration, limited numbers of anatomic sites involved, good performance status and good response to chemotherapy were significantly associated with long survival time. Drug toxicity was not apparent, and about half of patients were treated in an outpatient setting.

    Among combined radio-chemotherapy regimens of advanced head and neck tumors four modalities can be discriminated: 1. Induction chemotherapy, 2. simultaneous radio-chemotherapy, 3. adjuvant chemotherapy, 4. accelerated-hyperfractionated radiotherapy and chemotherapy. The results of the presently available randomized trials are as follows: 1. Induction chemotherapy has no influence on long-term recurrence-free survival. 2. With respect to simultaneous radio-chemotherapy, recurrence-free survival has been unproved with 5-FU and Mitomycin C. 3. There is evidence that adjuvant cis-platin therapy improves recurrence-free survival. 4. No results are available to date using hyperfractionated accelerated radiotherapy regimens in combination with chemotherapy. (orig.) [de

    This study is a retrospective evaluation of the efficacy of neoadjuvant chemotherapy (NC) with a vinorelbine (V) and epirubicin (E) intravenous combination regimen and is aimed at identification of predictive markers for the long-term outcome in noninflammatory locally advanced breast cancer (NLABC). One-hundred-and-nineteen patients with NLABC were identified from September 2001 to May 2006. Analysis was performed in March 2008, with a median follow-up of 63.4 months (range, 9-76 months). All patients were diagnosed with invasive breast cancer using 14 G core needle biopsy and treated with three cycles of VE before surgery. Local-regional radiotherapy was offered to all patients after the completion of chemotherapy followed by hormonal therapy according to hormone receptor status. Tissue sections cut from formalin-fixed paraffin-embedded blocks from biopsy specimens and postoperative tumor tissues were stained for the presence of estrogen receptor (ER), progesterone receptor (PgR), HER-2 (human epidermal growth factor receptor-2), and MIB-1(Ki-67). Patients characteristics were median age 52 years (range: 25-70 years); clinical TNM stage, stage IIB (n = 32), stage IIIA (n = 56), stage IIIB (n = 22) and stage IIIC (n = 9). All patients were evaluable for response: clinically complete response was documented in 27 patients (22.7%); 78 (65.6%) obtained partial response; stable disease was observed in 13 (10.9%); 1 patient (0.8%) had progressive disease. Pathological complete response was found in 22 cases (18.5%). Seventy-five patients were alive with no recurrence after a median follow-up of 63.4 months, the 5-year rates for disease-free survival and overall survival were 58.7% and 71.3%, respectively, after the start of NC. On multivariate analysis, the independent variables associated with increased risk of relapse and death were high pre-Ki-67(p = 0.012, p = 0.017, respectively), high post-Ki-67 expression (p = 0.045, p = 0.001, respectively), and non-pCR (p = 0

  17. Extravasation of chemotherapy

    Extravasation of chemotherapy is a feared complication of anticancer therapy. The accidental leakage of cytostatic agents into the perivascular tissues may have devastating short-term and long-term consequences for patients. In recent years, the increased focus on chemotherapy extravasation has led...... to the development of international guidelines that have proven useful tools in daily clinical practice. Moreover, the tissue destruction in one of the most dreaded types of extravasation (ie, anthracycline extravasation) now can effectively be prevented with a specific antidote, dexrazoxane....

    Chemotherapy-induced polyneuropathy (CIPN) is a common, but underestimated, clinical challenge. Incidence varies depending on many factors that are equally as important as the type of chemotherapeutic agent itself. Moreover, the assessment of CIPN is still uncertain, as several of the most...... frequently used scales do not rely on a formal neurological evaluation and depend on patients' reports and examiners' interpretations. Therefore, the aim of this MiniReview was to introduce the most common chemotherapies that cause neuropathy, and in addition to this, highlight the most significant...

    To present a unique case of transient, asymptomatic chemotherapy-induced hypocalcemia not attributable to hypomagnesemia or tumor lysis syndrome and review causes of hypocalcemia related to cancer with and without use of chemotherapy. We present a case detailing the clinical and laboratory findings of a patient who had severe hypocalcemia during chemotherapy and discuss causes of hypocalcemia with an extensive literature review of chemotherapeutic agents associated with this biochemical abnormality. In a 90-year-old man, hypocalcemia developed during 2 courses of chemotherapy for Hodgkin lymphoma, with partial recovery between courses and normal serum calcium 10 months after completion of treatment. Magnesium, vitamin D, and parathyroid hormone levels were low normal. There was no evidence of tumor lysis syndrome. Of the various agents administered, vinca alkaloids seemed the most likely cause. Serial testing suggested that the underlying mechanism may have been acquired, reversible hypoparathyroidism. No other similar case was found in the published literature. The severe hypocalcemia in our patient could not be attributed to hypomagnesemia or tumor lysis syndrome, and it was clearly associated with the timing of his chemotherapeutic regimen. Possibilities include direct parathyroid hormone suppression or alteration of calcium sensing by the chemotherapeutic drugs. Serum calcium surveillance before and during chemotherapeutic management of cancer patients may reveal more instances and provide insight into the exact mechanism of this lesser known yet striking complication.

    The National Institute for Health and Care Excellence (NICE) invited the manufacturer of aflibercept (Sanofi) to submit clinical and cost-effectiveness evidence for aflibercept in combination with irinotecan and fluorouracil-based therapy [irinotecan/5-fluorouracil/folinic acid (FOLFIRI)] for the treatment of metastatic colorectal cancer which has progressed following prior oxaliplatin-based chemotherapy, as part of the Institute's Single Technology Appraisal process. The Centre for Reviews and Dissemination and Centre for Health Economics at the University of York were commissioned to act as the independent Evidence Review Group (ERG). This article provides a description of the company submission, the ERG review and the resulting NICE guidance TA307 issued in March 2014. The ERG critically reviewed the evidence presented in the manufacturer's submission and identified areas requiring clarification, for which the manufacturer provided additional evidence. The clinical effectiveness data were derived from one good-quality double-blind randomised controlled trial (RCT), the VELOUR trial, which compared aflibercept plus FOLFIRI with placebo plus FOLFIRI. This RCT found a small but statistically significant increase in overall survival (OS); the difference in median OS was 1.44 months (13.5 months in the aflibercept group and 12.06 months in the placebo group). There was also a statistically significant increase in progression-free survival (PFS) with aflibercept; the difference in median PFS was 2.23 months (6.9 months in the aflibercept group and 4.67 months in the placebo group). However, grade 3-4 adverse events were more frequent in the aflibercept group than the placebo group: 83.5% compared with 62.5%. Treatment-emergent adverse events led to permanent discontinuation of treatment in 26.8% of patients in the aflibercept group and 12.1% of patients in the placebo group. The manufacturer's submission included an estimation of mean OS benefit based on extrapolation

    Trastuzumab (Herceptin) is the first humanized monoclonal antibody targeting the HER2 antigen in breast cancer. HER2 receptor has been individualised 20 years ago. During the past 10 years, trastuzumab administration has radically modified the prognosis of the patients that are treated for HER2 positive breast cancer. Its efficacy has been demonstrated in the metastatic and adjuvant settings. While, trastuzumab based-regimens became the standard of care in the treatment of HER2/neu positive breast cancer, the optimal combination (concurrently or sequentially) to chemotherapy and radiation therapy is still unknown. Indeed, while the concurrent administration of trastuzumab and anthracyclines is not recommended because of a high risk of cardiac toxicity, there is no published data on the best sequence of trastuzumab and radiation therapy administration, particularly when internal mammary chain is involved. The benefit/risk ratio of the concurrent and sequential administration of trastuzumab with chemotherapy and radiation therapy will be discussed in this review. (authors)
