    Abstract Background. Induction chemotherapy with cisplatin and fluorouracil and radiotherapy is an effective alternative to surgery in patients with carcinoma of the larynx and hypopharynx who are treated for organ preservation. Methods. We designed a protocol to evaluate the possibility of organ preservation in patients with advanced, resectable carcinoma of the larynx and hypopharynx. Forty-five eligible patients who were followed up between April 1999 and May 2001 were enrolled. Initially, these patients were treated with two cycles of induction chemotherapy consisting of cisplatin, 20 mg/m2/day on days 1 to 5, and 5-fluorouracil, 600 mg/m2/day by continuous infusion on days 1 to 5. Patients who had a complete response to chemotherapy were treated with definitive radiotherapy; patients who had a partial response to chemotherapy were treated with chemoradiotherapy. Cisplatin, 35 mg/m2/week, was introduced throughout the duration of radiotherapy. Patients who had no response or progressive disease underwent surgery with postoperative radiotherapy. Patients with N2 or N3 positive lymph nodes underwent neck dissection after the treatment. Results. The mean age was 56.6 years (range, 34,75 years). The overall response rate to induction chemotherapy was 71.1%, with a 17.8% complete response rate and 53.3% partial response rate. With a median follow-up of 13.7 months, 23 (51.1%) of all patients and 63.3% of surviving patients have had a preservation of the larynx or hypopharynx and remain disease free. The most common toxicities were nausea and vomiting and mucositis. Conclusion. Organ preservation, with multimodality treatment, may be achievable in some of the patients with resectable, advanced larynx or hypopharynx cancers without apparent compromise of survival. © 2004 Wiley Periodicals, Inc.

    Pilot study: rapamycin in advanced hepatocellular carcinoma

    ALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 6 2010
    M. Schöniger-Hekele
    Summary Background, The PI3K/Akt/mTOR signal pathway is involved in hepatocarcinogenesis. Rapamycin (=sirolimus), a specific mTOR inhibitor, leads to G(1) arrest of many malignant cell lines and currently, analogues of rapamycin are being investigated as a cancer chemotherapeutic adjuvant. Aim, To study the toxicity and tolerability of rapamycin therapy in patients with advanced hepatocellular carcinoma (HCC). Methods, Between June 2005 and February 2007, patients with advanced HCC, not eligible for any established therapy, were included in the study. Results, Eighteen patients (F/M: 5/13) with compensated liver cirrhosis (Child A n = 11, Child B n = 5, Child C n = 2) and histologically proven HCC were included in this study. According to the BCLC staging system, most of the patients enrolled had an advanced HCC: BCLC stage B: n = 2, Barcelona Clinic Liver-Cancer (BCLC) stage C: n = 14, BCLC stage D: n = 2. Overall, therapy with rapamycin was well tolerated. Most common toxicities were thrombocytopaenia and anaemia. We did not observe any partial or complete tumour response. At 3 months, two patients had stable disease and at 6 months, all patients had progressed. The median overall survival was 5.27 months, median time to progression was 3 months. Conclusion, Rapamycin is well tolerated in patients with advanced HCC, but only minimally effective. [source]

    Phase II study of bryostatin 1 and vincristine for aggressive non-Hodgkin lymphoma relapsing after an autologous stem cell transplant,

    AMERICAN JOURNAL OF HEMATOLOGY, Issue 8 2009
    Paul M. Barr
    Bryostatin 1, isolated from a marine bryozoan, enhances the efficacy of cytotoxic agents through modulation of the protein kinase C pathway and is active in combination with vincristine for diffuse large B-cell lymphoma. Further, the apoptotic frequency of peripheral blood T lymphocytes as determined by flow cytometry may predict which patients will respond to this combination. We tested the efficacy and safety of bryostatin 1 50 ,g/m2 given over 24 hr and vincristine 1.4 mg/m2 on days 1 and 15 every 28 days in aggressive B-cell non-Hodgkin lymphoma (NHL) relapsing after autologous stem cell transplantation. End points included tumor response, toxicity, and survival. Responses were correlated with an increase in apoptotic frequency of CD5+ cells by flow cytometry using annexin V staining. Fourteen patients were enrolled with 13 being evaluable for a response. The overall response rate was 31% with two patients achieving a complete response. The most common toxicities were Grade 3 lymphopenia (seven patients), Grade 3 to 4 neutropenia (two patients), and Grade 3 hypophosphatemia (two patients). Median progression-free and overall survivals for all patients were 5.7 and 21.4 months, respectively. One patient demonstrated an increase in T-cell apoptotic frequency, also achieving a complete response. Bryostatin 1 and vincristine have efficacy in select patients with aggressive NHL. Future investigations of agents targeting the protein kinase C pathway may benefit from early response assessment using flow cytometry to evaluate T-cell apoptosis. Am. J.

    Efficacy and safety of the combination of rituximab, fludarabine, and mitoxantrone for rituximab-naive, recurrent/refractory follicular non-Hodgkin lymphoma with high tumor burden,

    CANCER, Issue 18 2010
    A multicenter phase 2 trial by the Groupe d'Etude des Lymphomes de l'Adulte (GELA), Groupe Ouest Est des Leucémies et Autres Maladies du Sang (GOELAMS)
    Abstract BACKGROUND: This phase 2 trial was undertaken to evaluate the efficacy and safety of rituximab combined with intravenous fludarabine and mitoxantrone (R-FM) for patients with recurrent/refractory follicular lymphoma who had high tumor burden according to Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria. METHODS: Fifty patients were enrolled who had received a maximum of 2 previous regimens, including 1 cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)/CHOP-like regimen but no previous exposure to rituximab, fludarabine, or mitoxantrone. At baseline, 58% of patients had bulky disease (lesion >7cm), 56% had high-risk Follicular Lymphoma International Prognostic Index (FLIPI) scores (range, 3-5), and 22% were refractory. Treatment consisted of 4 courses of R-FM (rituximab 375 mg/m2 intravenously on Day 1, fludarabine 25 mg/m2 intravenously on Days 2 through 4, and mitoxantrone 10 mg/m2 intravenously on Day 2, recycling at Day 28) and consolidation with 2 courses of fludarabine and mitoxantrone (the same regimen without rituximab). RESULTS: The best response (84% overall response rate including 68% complete response/complete response unconfirmed) was achieved after 4 courses of R-FM. Response rates were high regardless of age, refractoriness to last previous therapy, and FLIPI score. After a median follow-up of 4 years, the 3-year progression-free survival rate was 47%, the event-free survival rate was 41%, and the 3-year overall survival rate was 66%. Grade ,3 neutropenia and infections were the most common toxicities and occurred in 72% and 14% of patients, respectively. CONCLUSIONS: Cytoreduction with 4 courses of R-FM was safe and highly efficient in patients with recurrent/refractory follicular lymphoma who had high tumor burden; however, better consolidation than FM is needed to further improve outcome.

    Erlotinib plus bevacizumab in previously treated patients with malignant pleural mesothelioma

    CANCER, Issue 4 2008
    David M. Jackman MD
    Abstract BACKGROUND. We conducted a phase 2, multicenter, open-label study of erlotinib plus bevacizumab in patients with malignant pleural mesothelioma who had previously received 1 prior chemotherapy regimen. These agents have activity in non,small cell lung cancer, but their role in mesothelioma is unclear. The primary endpoint is response rate. Secondary endpoints include time to progression, survival, and toxicity. METHODS. Eligible patients with mesothelioma who had previously received 1 chemotherapy regimen were treated with erlotinib 150 mg per os daily and bevacizumab 15 mg/kg administered intravenously on Day 1 of a 21-day cycle. Treatment continued until disease progression or development of significant toxicity. Tumor response was assessed after every 2 cycles using previously established mesothelioma response criteria from Byrne and Nowak. RESULTS. Twenty-four eligible patients initiated therapy with erlotinib and bevacizumab between February 2004 and October 2006. There were no complete or partial responses, although 12 patients achieved stable disease for at least 2 cycles of treatment. The median time to progression was 2.2 months (95% confidence interval [CI], 1.4 months-5.9 months). The median survival was 5.8 months (95% CI, 2.8 months-10.1 months). The most common toxicities were rash and diarrhea. There were no treatment-related deaths, intracranial bleeding, or hemoptysis. CONCLUSIONS. The combination of erlotinib and bevacizumab was tolerated reasonably well, but there was no evidence of radiographic response. This study demonstrates the feasibility of conducting trials in mesothelioma patients who have failed first-line therapy. More therapeutic studies with effective agents are needed for these patients.

    Activity of interferon-, and isotretinoin in patients with advanced, refractory lymphoid malignancies

    CANCER, Issue 3 2004
    Apostolia-Maria Tsimberidou M.D., Ph.D.
    Abstract BACKGROUND Interferon-, (IFN-,) and retinoids have shown nonoverlapping toxicity and each has shown antitumor activity in patients with lymphoma. The aim of the current study was to assess the toxicity, safety, and efficacy of IFN-, combined with isotretinoin in patients with advanced, refractory lymphoid malignancies. METHODS Adults with biopsy-proven advanced lymphoid malignancy were treated. Patients with compromised bone marrow function (platelet counts as low as 30 × 109/L) were eligible. Treatment was comprised of IFN-, at a starting daily dose of 3 mega units subcutaneously and isotretinoin orally starting at a dose of 1 mg/kg daily in 2 divided doses. RESULTS Forty-four patients were evaluable. Their median age was 57 years (range, 18,82 years). Eighteen patients had advanced cutaneous T-cell lymphoma, 6 patients had peripheral T-cell lymphoma, 14 patients had Hodgkin disease, and 6 patients had a variety of other lymphoid malignancies. Patients with Hodgkin disease had received a median of 6 previous therapies (range, 3,12 therapies) and patients with other lymphoid malignancies had received a median of 4 previous therapies (range, 1,9 therapies). The median duration of treatment was 4 months (range, 0.25,38 months). The overall response rate was 38.6% (complete response in 5 patients [11.3%] and partial response in 12 patients [27.3%]). The median response duration was 3 months (range, 1,95+ months). The most common toxicities were low-grade fever, flu-like symptoms, and fatigue (IFN-, effects); dry mouth and skin and hypertriglyceridemia (cis-retinoic acid effects); and thrombocytopenia (which generally occurred in patients with low baseline platelet counts). CONCLUSIONS IFN-, and isotretinoin combination therapy had antitumor activity and was well tolerated in heavily pretreated patients with lymphoid malignancies.

    Phase II study of pentostatin in advanced T-cell lymphoid malignancies

    CANCER, Issue 2 2004
    Update of an M. D. Anderson Cancer Center series
    Abstract BACKGROUND The goal of the current study was to assess the toxicity, safety, and efficacy of pentostatin in patients with T-cell lymphoid malignancies. METHODS Patients were eligible if they had biopsy-proven T-cell lymphoma or leukemia and failure to respond to previous therapy or an expected complete response rate to conventional therapy of < 20%. Pentostatin was administered at an initial dose of 3.75 or 5.0 mg/m2 by intravenous bolus daily over a consecutive 3-day period every 3 weeks. RESULTS Forty-two of 44 patients enrolled in the study were evaluable. The median age of the patients was 62 years (range, 38,86 years). Patients received a median of 3 previous therapies (range, 0,10 previous therapies). Of these patients, 32 (76%) had mycosis fungoides/Sézary syndrome and 10 patients (24%) had other T-cell leukemias or lymphomas. The overall response rate was 54.8% (complete remission, 6 patients [14.3%]; partial remission, 17 patients [40.5%]). Durable responses were observed mainly in patients with Sézary syndrome or peripheral T-cell lymphoma. The median follow-up period for surviving patients was 20 months (range, 1,83+ months). The median duration of response was 4.3 months (range, 1,61 months). The most common toxicities were neutropenia, nausea, and CD4 suppression. A transient early ,flare' of disease was observed in some responders. CONCLUSIONS At these doses, pentostatin was reasonably well tolerated and is an effective drug for the treatment of T-cell lymphomas. Cancer 2004;100:342,9. © 2003 American Cancer Society. [source]

    Weekly 5-fluorouracil plus cisplatin for concurrent chemoradiotherapy in patients with locally advanced head and neck cancer

    HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2010
    Young Joo Lee MD
    Abstract Background. In locally advanced head and neck cancer, concurrent chemoradiotherapy (CRT) with combined 5-fluorouracil (5-FU) and cisplatin has increased acute toxicities as well as survival. Once-weekly chemotherapeutic administration schedule may reduce severe toxicities. Thus, we investigated CRT using weekly administration of 5-FU,cisplatin in locally advanced head and neck cancer. Methods. In a single-arm, phase II study, CRT included radiation (70.0 Gy/35 fr) and weekly 5-FU (750 mg/m2) and cisplatin (20 mg/m2). Results. Thirty-two patients completed planned radiation. Thirteen (41%) achieved complete response, and 16 (50%) partial response. Twelve patients (38%) experienced acute grade 3 toxicities. Grade 3 mucositis, which was the most common toxicity, developed in 5 (16%) patients. The survival rates at 1 and 2 years were 81% and 76%, respectively. The progression-free survival rates at 1 and 2 years were 69% and 66%, respectively. Conclusions. We demonstrated weekly 5-FU-cisplatin with conventional radiotherapy was efficacious and feasible with high compliance rate in locally advanced head and neck cancer. © 2009 Wiley Periodicals, Inc.

    A phase 2 trial of all- trans -retinoic acid in combination with interferon-,2a in children with recurrent neuroblastoma or Wilms tumor: A Pediatric Oncology Branch, NCI and Children's Oncology Group Study

    PEDIATRIC BLOOD & CANCER, Issue 5 2007
    Peter C. Adamson MD
    Abstract Background The combination of the antiproliferative and differentiation-inducing effects of retinoids together with the antiproliferative, immunostimulatory, and differentiation-potentiating effects of interferon-, (IFN-,) were the basis for the development of this combination in pediatric patients with refractory neuroblastoma or Wilms tumor. Procedure A phase 2 trial of all- trans -retinoic acid (ATRA), administered orally at a dose of 90 mg/m2/day in three divided doses for 3 consecutive days per week, and IFN-,2a, administered subcutaneously daily at a dose of 3,×,106 U/m2/day for 5 consecutive days per week, in 4 week cycles was performed. A two-stage design was used for each disease stratum. Results Seventeen patients (16 evaluable) with neuroblastoma, median age 9 years, and 15 patients (14 evaluable) with Wilms tumor, median age 6 years, were enrolled. Overall, the combination was well tolerated, with headache being the most common toxicity observed. There were no complete or partial responses. The median number of cycles administered was 1 (range 1,9). Four patients with neuroblastoma had stable disease for 12 or more weeks. Conclusions The combination of ATRA and IFN-,2a was inactive in children with relapsed or refractory neuroblastoma and Wilms tumor. The lack of activity with this combination in children with refractory neuroblastoma is similar to the disappointing phase 2 results of single agent 13- cis -retinoic-acid (13cRA) and does not support further development of ATRA for children with relapsed neuroblastoma.

    Prospective analysis of treatment outcome and prognostic factors in patients with T-cell lymphomas treated by CEOP-B: single institutional study

    BRITISH JOURNAL OF HAEMATOLOGY, Issue 1 2006
    Hwa Jung Sung
    Summary The important prognostic factors were evaluated for T-cell non-Hodgkin lymphoma (NHL) patients in a prospective study using the CEOP-B protocol [a modified cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP)-like regimen that uses epirubicin instead of doxorubicin with the addition of bleomycin]. Fifty-two patients were enrolled in the study. The overall response rate was 63·5%. The median progression-free survival (PFS) and median overall survival (OS) was 18·0 and 39·5 months respectively. The most common toxicity was neutropenia. The factors related to poor outcome were a high International Prognostic Index (IPI) and a high ,B' score (bone marrow involvement, B symptoms, bulky disease). We developed a new prognostic model, namely the Prognostic Group for T cell NHL (PGT) that included four groups: PGT1 (low IPI/low B score), PGT2 (low IPI/high B score), PGT3 (high IPI/Low B score) and PGT4 (high IPI/Low B score). OS and PFS (not reached, 48 months) in the PGT1 group were significantly longer than those (11·5 and 4·8 months) in PGT2. The same result was observed in the PGT3 and PGT4 groups. The CEOP-B regimen was moderately active and tolerable for T-cell NHL patients, and the PGT system might be useful for the prediction of long-term survival of T-cell NHL patients. [source]
