A new schedule of fotemustine in temozolomide-pretreated patients with relapsing glioblastoma.

In the present study we investigated the feasibility and effectiveness of a new biweekly schedule of fotemustine (FTM) in patients with recurrent glioblastoma, after at least one previous treatment. The primary endpoint was progression-free survival at 6 months; secondary objectives were clinical response, overall survival, disease-free survival, and toxicity. Forty patients (median age 52.8 years; median Karnofsky Performance Status at progression 90) underwent second-line chemotherapy with FTM. Selected patients were previously treated with a standard radiotherapy course with concomitant temozolomide (TMZ). After tumor relapse or progression proven by magnetic resonance imaging (MRI), all patients underwent chemotherapy with FTM, given intravenously at dose of 80 mg/m(2) every 2 weeks for five consecutive administrations (induction phase), and then every 4 weeks at 80 [DOSAGE ERROR CORRECTED] mg/m(2) as maintenance. A total of 329 infusions were administered; the median number of cycles administered was 8. All patients completed the induction phase, and 29 patients received at least one maintenance infusion. Response to treatment was assessed using MacDonald criteria. One complete response [2.5%, 95% confidence interval (CI): 0-10%], 9 partial responses (22.5%, 95% CI: 15-37%), and 16 stable diseases (40%, 95% CI: 32-51%) were observed. Median time to progression was 6.7 months (95% CI: 3.9-9.1 months). Progression-free survival at 6 months was 61%. Median survival from beginning of FTM chemotherapy was 11.1 months. The schedule was generally well tolerated; the main toxicities were hematologic (grade 3 thrombocytopenia in two cases). To the best of our knowledge, this is the first report specifically dealing with the use of a biweekly induction schedule of FTM. The study demonstrates that FTM has therapeutic efficacy as single-drug second-line chemotherapy with a favorable safety profile.

Low-dose metronomic oral administration of vinorelbine in the first-line treatment of elderly patients with metastatic breast cancer.

BACKGROUND: The concept of metronomic chronic administration of low-dose chemotherapy has become relevant for the treatment of cancer in the last several years. This study sought to determine the safety and activity of oral vinorelbine (VNB), using a metronomic schedule of administration, in elderly patients with metastatic breast cancer (MBC). PATIENTS AND METHODS: From October 2004 to March 2007, 34 patients with MBC (median age, 74 years; range, 70-84 years) were treated with oral VNB at 70 mg/m2, fractionated on days 1, 3, and 5, for 3 weeks on and 1 week off, every 4 weeks, for a maximum of 12 cycles. The objective response rate was the primary endpoint. RESULTS: All 34 patients received at least 3 cycles of therapy and were evaluable. Two achieved complete responses (6%), and 11 achieved partial responses (32%). Median progression-free survival and median overall survival entailed 7.7 months (95% confidence interval, 6.9-9.05 months) and 15.9 months (95% CI, 13.1-15.91 months), respectively, for all patients. CONCLUSION: The fractionated administration of oral VNB is well tolerated and presents promising activity in elderly patients with metastatic cancer, warranting further investigation in combination with other chemotherapy agents.

Zoledronic acid in the treatment of bone metastases by hepatocellular carcinoma: a case series.

PURPOSE: The survival of patients with hepatocellular carcinoma (HCC) has improved with advancements in various diagnostic tools and treatment modalities. Consequently, bone metastases from HCC are diagnosed more frequently. The aims of the present study was to describe the clinical features and treatment of HCC patients presenting with bone metastases. In particular, we evaluated the role of zoledronic acid in these patients especially with regard to pain reduction, analgesic drug consumption and safety. METHODS: Between December 2006 and July 2008, we recruited 17 (male:female, 12:5, median age, 68 years; age range, 62-85 years) consecutive patients. Spinal metastases were present in 11 patients (64.7%). Zoledronic acid was administered in all patients (total number of administrations, 107; mean number of administrations, 6.29). RESULTS: A total of 15 patients received at least three administrations of zoledronic acid and reported clinical benefit with pain reduction and tapering of analgesic drugs. Before starting treatment, the mean VAS for patients who received at least three administrations (15/17 patients) of zoledronic acid was 7.1 (+/-0.24), and after 3 months 5.3 (+/-0.20). This improvement was independent of the sex, the extent of metastasis and the concomitant anticancer treatment. No significant side effects were registered in this series of patients. Median survival was 10 months (CI 6,353-13,647). CONCLUSIONS: Zoledronic acid may be helpful in treating bone metastases in HCC patients. Patients regularly receiving zoledronic acid showed significant pain relief.

Randomized phase III trial on gemcitabine versus mytomicin in recurrent superficial bladder cancer: evaluation of efficacy and tolerance.

PURPOSE: Approximately 30% to 40% patients with a superficial bladder cancer treated with Bacille Calmette-Guerin (BCG) or epirubicin do not respond; of the initial responders, 35% have a relapse within 5 years. We compare the therapeutic efficacy and toxicity of intravescical infusions of gemcitabine (GEM) with mitomycin (MMC) in patients with a recurrent superficial bladder cancer. PATIENTS AND METHODS: Patients with a history of a previously treated, recurrent Ta-T1, G1-G3 bladder transitional cell carcinoma were enrolled in the study. The patients received a 6-week course of GEM infusions or 4-week course of MMC. In both arms, for the initial responders who remained free of recurrences, maintenance therapy consisted of 10 monthly treatments during the first year. RESULTS: A total of 120 patients were enrolled and randomly assigned to either the MMC or GEM treatment arm. At the end of the study, 109 patients (55 in MMC and 54 in GEM) were assessable. The median duration of follow-up was 36 months for either arm. In the GEM arm, 39 (72%) of 54 patients remained free of recurrence versus 33 (61%) of 55 in MMC arm. Among patients with recurrences, 10 in the MMC arm and six in the GEM arm also had a progressive disease by stage. The incidence of chemical cystitis in the MMC arm was statistically higher than in the GEM arm (P = .012). CONCLUSION: This study demonstrates that GEM has better efficacy and lower toxicity than MMC; therefore, GEM appears as a logical candidate for intrabladder therapy in patients with refractory transitional cancer.

Sorafenib plus octreotide is an effective and safe treatment in advanced hepatocellular carcinoma: multicenter phase II So.LAR. study.

PURPOSE: Advanced hepatocellular carcinoma (HCC) not eligible for local therapies has limited chances of cure. Sorafenib is a multikinase inhibitor with proven activity in advanced HCC. Octreotide is used in this setting with conflicting results. Treatment with sorafenib and long-acting octreotide was tested in advanced HCC to evaluate safety and activity. METHODS: Fifty patients with advanced HCC, Child-Pugh A or B, received sorafenib at a dosage of 800 mg/day for 28 days with a following week of rest and long-acting octreotide at a dose of 40 mg, administered every 28 days. RESULTS: All patients were assessable for safety and efficacy. Sixteen patients out of 50 (34%) were naïve from other therapies, while all the others were previously treated with local and/or systemic treatments. We achieved 5 partial responses (10%), 33 stable diseases (66%) and 12 progressions of disease (24%). Median time to progression was 7.0 months (95% CI, 3.0-10.9 months), and median overall survival was 12 months (95% CI, 6.3-17.4 months). Treatment was well tolerated. Diarrhoea (6%) and hypertension (4%) were the most frequent grade 3 toxicities. CONCLUSIONS: Our data suggest that the combination between sorafenib and long-acting octreotide is active and well tolerated in patients with advanced HCC and could represent another efficacious chance for the management of this population.

Zoledronic acid in metastatic chondrosarcoma and advanced sacrum chordoma: two case reports.

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

Phase 2 trial of temozolomide using protracted low-dose and whole-brain radiotherapy for nonsmall cell lung cancer and breast cancer patients with brain metastases.

BACKGROUND: Temozolomide (TMZ), an oral methylating imidazotetrazinone, has antitumor activity against gliomas, malignant melanomas, and brain metastasis and is presently administered as a 5-day oral schedule every 4 weeks. METHODS: A single-institution phase 2 clinical trial was conducted to determine the efficacy and the safety profile of a new regimen based on a dose-intensified, protracted course of TMZ after whole-brain radiotherapy (WBRT). Patients were eligible if they had at least 1 bidimensionally measurable brain metastasis from breast cancer and nonsmall cell lung cancer (NSCLC). Twenty-seven patients were treated with 30 grays (Gy) of WBRT with concomitant TMZ (75 mg/m(2)/day) for 10 days, and subsequent TMZ at a dose of 75 mg/m(2) per day for 21 days every 4 weeks, for up to 12 cycles. RESULTS: Two complete responses (7.4%) and 11 partial responses (40.7%) were achieved. The schedule appeared to be well tolerated, with grade 3 toxicity (graded according to National Cancer Institute Common Toxicity Criteria) observed in only 2 patients. The overall median survival was 8.8 months and the median progression-free survival was 6 months. CONCLUSIONS: The concomitant use of WBRT and protracted low-dose TMZ appears to be an active, well-tolerated regimen. The observed antitumor activity suggests the need for further investigation of this schedule in combination with other anticancer agents for the concomitant treatment of brain metastases and primary cancers.

Liposomal pegylated doxorubicin plus vinorelbine combination as first-line chemotherapy for metastatic breast cancer in elderly women > or = 65 years of age.

PURPOSE: No standard chemotherapy has been so far definitely settled for elderly patients with metastatic breast cancer (MBC). In order to identify a regimen with acceptable efficacy and low burden of non-overlapping toxic effects, a combination consisting of liposomal pegilated doxorubicin (PLD) with alternating oral and intravenous vinorelbine (NVB) has been investigated in a phase II study. METHODS: Thirty-four consecutive patients (median age 71 years; range 65-82) with MBC have been enrolled. Based on 4-weekly cycles, PLD 40 mg/m(2) plus NVB 25 mg/m(2) i.v., have been administered intravenously on day 1 and oral NVB 60 mg/m(2) on day 15. RESULTS: All patients were assessable for safety and efficacy. In all, 17 responses were documented with three complete responses (CR) and 14 partial responses, with an overall response rate of 50% (95% CI 36-66). Median overall survival time was 13 months and the median time to progression 8 months. Interestingly, all the patients with CR are still alive with a disease-free survival of more than 1 year. The main toxicity was neutropenia: grade 3 in 15% and grade 4 in 11% of patients, respectively. Febrile neutropenia was recorded in three patients not requiring dose reduction. Other frequently reported adverse events included: anemia, nausea, vomiting, stomatitis, all rarely severe. The evaluation of quality of life (QoL) did not show any significant change during the study. CONCLUSIONS: Our data suggest that this combination is active and well tolerated in elderly patients with MBC and could represent another efficacious chance for the management of this population.

Management of pain in elderly patients receiving infusion of zoledronic acid for bone metastasis: a single-institution report.

GOALS OF WORK: Bone metastases are a common cause of morbidity in elderly patients with solid tumors and myeloma. We studied the safety and the effect of a new bisphosphonate, zoledronic acid (ZA), on pain and on quality of life (QoL) in elderly patients with bone metastases. MATERIALS AND METHODS: From January 2004 to December 2005, we have enrolled elderly patients with bone metastasis for receiving ZA administration. Visual analog scale (VAS) and Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire were used to assess potential benefits of ZA therapy. RESULTS: Eighty-six patients were included; the median age was 75.5 years. Before starting treatment, the mean VAS was 6.8 (+/-0.24), after three infusions 5.4 (+/-0.3), and after six courses 4.5 (+/-0.3) with a significant improvement of bone pain. Moreover, we found a statistically significant improvement of QoL measured by FACT-G questionnaire after six courses (p = 0.010). Median baseline and final value of serum creatinine were 0.73 and 0.72 mg/dl, respectively (p = 0.11); creatinine clearance was also normal for most patients. Osteonecrosis of the jaw was diagnosed in one patient who received a prolonged ZA treatment. CONCLUSIONS: These data confirm the benefits of ZA on pain and QoL also in elderly patients with bone metastasis from solid tumors.

Atypical cutaneous lymphoid hyperplasia induced by chemotherapy in a patient with advanced colon carcinoma.

Some conditions are predisposed to excessive lymphocyte responses, which can progress to a benign condition, ie, atypical cutaneous lymphoid hyperplasia (ACLH), or a malignant lymphoma. Clinical diagnosis of drug-associated pseudolymphoma can be based on a temporal association between drug ingestion and lesion onset followed by resolution without recurrence after discontinuation of drug administration. Herein, we report the case of a 66-year-old man with advanced colon carcinoma with ACLH developed while receiving chemotherapy regimen with oxaliplatin/5-fluorouracil/leucovorin. The authors postulate that chemotherapy can promote an aberrant immune response to an antigen that can be the drug itself or other self-antigens.

Concomitant treatment of brain metastasis with whole brain radiotherapy [WBRT] and temozolomide [TMZ] is active and improves quality of life.

BACKGROUND: Brain metastases (BM) represent one of the most frequent complications related to cancer, and their treatment continues to evolve. We have evaluated the activity, toxicity and the impact on Quality of Life (QoL) of a concomitant treatment with whole brain radiotherapy (WBRT) and Temozolomide (TMZ) in patients with brain metastases from solid tumors in a prospective Simon two stage study. METHODS: Fifty-nine patients were enrolled and received 30 Gy WBRT with concomitant TMZ (75 mg/m2/day) for ten days, and subsequently TMZ (150 mg/m2/day) for up to six cycles. The primary end points were clinical symptoms and radiologic response. RESULTS: Five patients had a complete response, 21 patients had a partial response, while 18 patients had stable disease. The overall response rate (45%) exceeded the target activity per study design. The median time to progression was 9 months. Median overall survival was 13 months. The most frequent toxicities included grade 3 neutropenia (15%) and anemia (13%), and only one patient developed a grade 4 thrombocytopenia. Age, Karnofsky performance status, presence of extracranial metastases and the recursive partitioning analysis (RPA) were found to be predictive factors for response in patients. Overall survival (OS) and progression-free survival (PFS) were dependent on age and on the RPA class. CONCLUSION: We conclude that this treatment is well tolerated, with an encouraging objective response rate, and a significant improvement in quality of life (p < 0.0001) demonstrated by FACT-G analysis. All patients answered the questionnaires and described themselves as 'independent' and able to act on their own initiatives. Our study found a high level of satisfaction for QoL, this provides useful information to share with patients in discussions regarding chemotherapy treatment of these lesions.

Phase II study of temozolomide plus pegylated liposomal doxorubicin in the treatment of brain metastases from solid tumours.

OBJECTIVE: A combination regimen of temozolomide (TMZ) and pegylated liposomal doxorubicin has been evaluated in the treatment of brain metastases from solid tumours. STUDY DESIGN: Nineteen consecutive patients (pts) have been enrolled in a prospective phase II trial and treated with TMZ 200 mg/m2 (days 1-5) and pegylated liposomal doxorubicin 35 mg/m2 (day 1) every 28 days. The study was prospectively projected according to the Simon's two-stage optimal design. RESULTS: Major toxicities have been grade III neutropenia and thrombocytopenia in one patient (pt) and grade III erythrodisesthesia in two pts. Three pts achieved a complete response (CR) and four a partial response (PR), for an overall response rate of 36.8% (95% CI: 19.1-59.2), which exceeded the target activity in the study design. A significant improvement in quality of life was demonstrated by FACT-G analysis. The median Progression Free Survival (PFS) was 5.5 (95% CI: 2.7-8.2) months while the median Overall Survival (OS) was 10.0 months (95% CI: 6.3-13.7). CONCLUSIONS: The TMZ/pegylated liposomal doxorubicin regimen was well tolerated with an encouraging activity in brain metastases from solid tumours.

Atrial fibrillation following chemotherapy for stage IIIE diffuse large B-cell gastric lymphoma in a patient with myotonic dystrophy (Steinert's disease).

The authors describe the unusual association between diffuse B-cell gastric lymphoma and myotonic dystrophy, the most common form of adult muscular dystrophy, and sudden atrial fibrillation following one cycle of doxorubicin-based chemotherapy in the same patient. Atrial fibrillation or other cardiac arrhythmias are unusual complications in patients treated with chemotherapy. The cardiac toxicity intrinsically associated with the aggressive chemotherapy employed could function as a triggering factor for the arrhythmia in the predisposed myocardium of this patient.

Oxaliplatin/rituximab combination in the treatment of intermediate-low grade non-Hodgkin's lymphoma of elderly patients.

High and intermediate grade non-Hodgkin's lymphomas (NHL) require treatments with aggressive chemotherapy schedules. However, low grade NHLs display a low chemoresponsiveness and patients aged >65 years often do not tolerate anthracycline and corticosteroid-containing chemotherapy regimens. Therapeutic options in this subset of patients are watchful waiting, oral alkylating agents, purine nucleoside analogues, combination chemotherapy, interferon and monoclonal antibodies. The approval of rituximab, an unconjugated chimeric antibody against the CD20 antigen for the treatment of B-cell NHL marked a milestone in the development of antibody treatment. Moreover, promising results have also been found with oxaliplatin in patients with NHL and reversible, cumulative, peripheral sensory neuropathy is the principle dose-limiting factor of oxaliplatin therapy. On the basis of these considerations we have performed a feasibility study in NHL in patients aged >65 years using as schedule: 130 mg/m2 oxaliplatin every 21 days and 375 mg/m2 rituximab weekly. We have enrolled 8 patients, 2 males and 6 females (mean age 69.2+/-3.1 years; median, 67 years) affected by intermediate or high grade stage III/IV NHL. Six patients have cardiac abnormalities (myocardial function between 45 and 50%) and 1 increase of transaminasemia due to active chronic hepatitis. All the patients included in the study were treated for at least 3 cycles and 31 cycles were completed. We have recorded grade I/II (CTC) neurotoxicity in 30%, grade I anemia in 25% and grade I neutropenia in 20% of the patients. No infusional reactions, liver or renal toxicity neither nausea and/or vomiting were recorded. One complete response, 3 partial response and 3 minimal response were obtained at 11 months of median time follow-up. These results demonstrate the feasibility of this schedule which offers a suitable alternative regimen to treat elderly patients with NHL and shows a good efficacy and an acceptable toxicity profile.
