  • Article: Progression of cutaneous melanoma: implications for treatment.
    [show abstract] [hide abstract]
    ABSTRACT: The survival rates of melanoma, like any type of cancer, become worse with advancing stage. Spectrum theory is most consistent with the progression of melanoma from the primary site to the in-transit locations, regional or sentinel lymph nodes and beyond to the distant sites. Therefore, early diagnosis and surgical treatment before its spread is the most effective treatment. Recently, new approaches have revolutionized the diagnosis and treatment of melanoma. Genomic profiling and sequencing will form the basis for molecular taxonomy for more accurate subgrouping of melanoma patients in the future. New insights of molecular mechanisms of metastasis are summarized in this review article. Sentinel lymph node biopsy has become a standard of care for staging primary melanoma without the need for a more morbid complete regional lymph node dissection. With recent developments in molecular biology and genomics, novel molecular targeted therapy is being developed through clinical trials.

    Article: Extended schedule, escalated dose temozolomide versus dacarbazine in stage IV melanoma: final results of a randomised phase III study (EORTC 18032).
    [show abstract] [hide abstract]
    ABSTRACT: To compare the efficacy of an extended schedule escalated dose of temozolomide versus standard dose dacarbazine in a large population of patients with stage IV melanoma. A total of 859 patients were randomised to receive oral temozolomide at 150 mg/m(2)/day for seven consecutive days every 2 weeks or dacarbazine, administered as an intravenous infusion at 1000 mg/m(2)/day on day 1 every 3 weeks. The primary endpoint was overall survival (OS), using an intent-to-treat principle. EudraCT number 2004-000654-23 NCI registration number NCT00005052. Median OS was 9.1 months in the temozolomide arm and 9.4 months in the dacarbazine arm, with a hazard ratio (HR) of 1.00 (95%confidence interval [CI]: 0.86, 1.17; P=0.99). Median progression-free survival (PFS) was 2.3 months in the temozolomide arm and 2.2 months in the dacarbazine arm, with a HR of 0.92 (95%CI: 0.80, 1.06; P=0.27). In patients with measurable disease, overall response rate was higher in the temozolomide arm than in the dacarbazine arm (14.5% versus 9.8%, respectively), but the median duration of response was longer for dacarbazine. The extended schedule, escalated dose temozolomide arm showed more toxicity than the standard dose, single agent dacarbazine arm. The most common non-haematological treatment emergent adverse events reported in both treatment arms were nausea, fatigue and vomiting and constipation. Extended schedule escalated dose Temozolomide (7 days on 7 days off) is feasible and has an acceptable safety profile, but does not improve OS and PFS in metastatic melanoma when compared to standard dose dacarbazine.

  • Article: Current and future adjuvant immunotherapies for melanoma: blockade of cytotoxic T-lymphocyte antigen-4 as a novel approach.
    Sanjiv S Agarwala, Steven J O'Day
    [show abstract] [hide abstract]
    ABSTRACT: The current treatment for melanoma with nodal involvement, but without distant metastasis, is surgical excision and lymph node dissection followed by adjuvant therapy. A number of systemic regimens have been evaluated for melanoma patients with a medium or high risk of disease recurrence following surgery. The only agent approved for the adjuvant therapy of melanoma is high-dose interferon (IFN)-α2b, which prolongs relapse-free survival, but its effects on overall survival remain controversial. Its use is also accompanied by significant toxicity. Thus, despite its approval, high-dose IFN-α2b is not always used for the adjuvant therapy of melanoma, particularly in countries other than the United States. Studies aimed at identifying subgroups of patients that have the greatest benefit-to-risk ratio with this regimen are ongoing. Several vaccines have been studied in the adjuvant setting for melanoma, but none has shown superiority to IFN-containing regimens. The GMK ganglioside vaccine, for instance, has actually been shown to be inferior to high-dose IFN-α2b. Therefore, a therapeutic regimen which improves overall survival with a favorable safety profile would be a major advance in the adjuvant therapy of melanoma. One approach that is currently being investigated is the potentiation of antitumour immune responses through blockade of cytotoxic T-lymphocyte antigen-4 (CTLA-4). Here, we provide an overview of the current unmet needs in the adjuvant therapy of melanoma and evaluate the potential of CTLA-4 blockade as a future therapeutic option in this setting.

  • Article: Results of a multicenter, randomized, double-blind, dose-evaluating phase 2/3 study of lenalidomide in the treatment of metastatic malignant melanoma.
    [show abstract] [hide abstract]
    ABSTRACT: There are currently no systemic treatments for stage IV melanoma, which have been proven in randomized trials to benefit overall survival (OS). Lenalidomide has efficacy against melanoma in animal models and safety in phase 1 trials. The authors reported the results of a phase 2/3 study comparing the safety and efficacy of 2 doses of lenalidomide in patients with relapsed metastatic melanoma disease refractory to previous treatment with dacarbazine, temozolomide, interleukin-2, or interferon-alpha. A total of 294 patients were randomized to oral lenalidomide at 5 mg or 25 mg dose. Tumor response, time to progression, and OS were evaluated. Treatment continued until disease progression or unacceptable adverse events. No significant differences in response rate, OS, or time to progression were observed between lenalidomide 25 mg versus 5 mg (overall response rate: 5.5% vs 3.4%, P = .38; median OS: 6.8 months vs 7.2 months, P = .71; and median time to progression: 2.2 months vs 1.9 months, P = .24). Myelosuppression was observed in 37.0% of patients in the 25 mg group and 13.7% of patients in the 5 mg group. Treatment-related serious adverse events were seen in 39.0% of patients at the 25 mg dose and 35.4% of patients at the 5 mg dose. Despite the occurrence of treatment-related serious adverse events, approximately 80% of patients continued treatment. The higher dose of lenalidomide did not improve response rate, time to progression, or OS of patients with relapsed/refractory stage IV melanoma. A parallel placebo-controlled study has been conducted to further assess the efficacy of lenalidomide in stage IV melanoma patients.

  • Article: LDH correlation with survival in advanced melanoma from two large, randomised trials (Oblimersen GM301 and EORTC 18951).
    [show abstract] [hide abstract]
    ABSTRACT: In a randomised study (GM301; dacarbazine with/without oblimersen), patients with advanced melanoma were stratified based on performance status, metastatic site and lactate dehydrogenase (LDH). Progression-free survival and response and durable response rates showed a highly significant difference favouring dacarbazine-oblimersen and a nearly significant survival difference. All efficacy parameters significantly favoured dacarbazine-oblimersen in patients with normal baseline LDH [1.1xupper limit of normal (ULN)]. Each stratification factor was assessed for an interaction with treatment on survival and an interaction was detected only for LDH. Baseline LDH values in Study GM301 treatment groups were combined and analysed using cutoffs above and below 1xULN. Baseline LDH in EORTC study 18951 (dacarbazine, cisplatin, interferon-alfa-2b with/without interleukin-2 in advanced melanoma) was independently analysed using the same approach. In Study GM301, the relation between treatment effect and LDH, treatment effect and tumour size, LDH and tumour size and LDH and disease site were determined. In Study GM301 (N=760) and Study 18951 (N=325), LDH was within the upper range of normal for a large number of patients. This was not exhibited in the general population, suggesting such values may be elevated rather than normal in melanoma. A highly ordered and monotonic relationship was apparent between LDH and survival: survival worsened as LDH became more elevated, even when LDH remained within normal range. LDH and tumour size were poorly correlated; elevated LDH was not associated with any one disease site. LDH was highly predictive of oblimersen effect. In designing studies, LDH should be considered, regardless of tumour size or disease site.

    [show abstract] [hide abstract]
    ABSTRACT: Metastatic melanoma remains a lethal disease with a long-term remission rate of less than 10%. Despite many years of research, there has not been a new drug approved in this disease in over two decades. Single-agent chemotherapy is palliative in some patients and there is no advantage of combination chemotherapy or chemo-immunotherapy in randomized trials. High-dose bolus IL-2 produces some long-term remissions and is available for highly selected individuals at selected centers in the USA but is impractical for most patients. Research is ongoing in exploring novel immunotherapeutic and targeted approaches. The status of recently completed and ongoing trials is discussed in this review.

    Article: Results of a phase III, randomized, placebo-controlled study of sorafenib in combination with carboplatin and paclitaxel as second-line treatment in patients with unresectable stage III or stage IV melanoma.
    [show abstract] [hide abstract]
    ABSTRACT: This phase III, randomized, double-blind, placebo-controlled study was conducted to evaluate the efficacy and safety of sorafenib with carboplatin and paclitaxel (CP) in patients with advanced melanoma who had progressed on a dacarbazine- or temozolomide-containing regimen. A total of 270 patients were randomly assigned to receive intravenous paclitaxel 225 mg/m2 plus intravenous carboplatin at area under curve 6 (AUC 6) on day 1 of a 21-day cycle followed by either placebo (n = 135) or oral sorafenib 400 mg (n = 135) twice daily on days 2 to 19. The primary efficacy end point was progression-free survival (PFS); secondary and tertiary end points included overall survival and incidence of best response, respectively. The median PFS was 17.9 weeks for the placebo plus CP arm and 17.4 weeks for the sorafenib plus CP arm (hazard ratio, 0.91; 99% CI, 0.63 to 1.31; two-sided log-rank test P = .49). Response rate was 11% with placebo versus 12% with sorafenib. Dermatologic events, grade 3 thrombocytopenia, diarrhea, and fatigue were more common in patients treated with sorafenib plus CP versus placebo plus CP. In this study, the addition of sorafenib to CP did not improve any of the end points over placebo plus CP and cannot be recommended in the second-line setting for patients with advanced melanoma. Both regimens had clinically acceptable toxicity profiles with no unexpected adverse events. A trial of similar design for the first-line treatment of patients with advanced melanoma (intergroup trial E2603) is currently ongoing.

  • Article: Intratumoral epidermal growth factor receptor antisense DNA therapy in head and neck cancer: first human application and potential antitumor mechanisms.
    [show abstract] [hide abstract]
    ABSTRACT: Squamous cell carcinoma of the head and neck (SCCHN) is characterized by upregulation of the epidermal growth factor receptor (EGFR). We developed a novel strategy to target EGFR by using a therapeutic gene that consisted of an EGFR antisense (AS) gene sequence under U6 promoter control. A phase I clinical trial was conducted to evaluate the safety and biologic effects of EGFR AS. Patients with advanced SCCHN who were refractory to standard therapies and who had at least one assessable and accessible lesion were enrolled. The EGFR AS dose was escalated in successive cohorts (six dose levels; 60 to 1,920 microg/injection). Patients received four weekly intratumoral EGFR AS injections. Tumor biopsies were performed before and after completion of therapy. Treatment response was assessed by tumor volume measurements (positron emission tomography/computed tomography), and levels of target proteins were assessed by immunohistochemistry. Seventeen assessable patients were treated. No grades 3 to 4 or dose-limiting toxicities were noted, and a maximum-tolerated dose was not reached. Five patients (29%) achieved a clinical response, which included two complete responses (CRs) and three partial responses (PRs); two additional patients had stable disease (SD) as the best response. Patients with disease control (CR + PR + SD) had tumors with higher EGFR and lower STAT3 expression at baseline compared with patients who had progressive disease (P = .0312 and P = .095, respectively). Intratumoral EGFR AS was safe and resulted in antitumor activity in patients with advanced SCCHN. Baseline levels of high EGFR and low STAT3 may be associated with antitumor effects.

  • Article: A phase 2 trial of sequential temozolomide chemotherapy followed by high-dose interleukin 2 immunotherapy for metastatic melanoma.
    [show abstract] [hide abstract]
    ABSTRACT: Previous biochemotherapy regimens for metastatic melanoma have required attenuated dosages of interleukin 2 (IL-2) that may have compromised efficacy. In a phase 2 study, the authors tested sequential temozolomide (75 mg/m2 per day orally for 3 weeks) followed by high-dose, IL-2 (600,000 U/kg per dose intravenously; maximum, 14 doses over 5 days). Thirty-eight patients with treatment-naive American Joint Committee on Cancer stage IV melanoma (8 patients with M1a disease, 6 patients with M1b disease, and 24 patients with M1c disease) were enrolled. Ten patients had a history of treated brain metastases. Thirty-one patients who received at least 2 cycles of IL-2 were evaluable for response. Grade 3 toxicities included hyperbilirubinemia (9 patients), hematologic toxicities (leukopenia in 5 patients, thrombocytopenia in 3 patients), diarrhea (2 patients), and oliguria (1 patient). One patient had grade 4 nausea. The overall response rate (ORR) was 16% and included 3 complete responses that lasted 10.8 months, > or =32 months, and > or =36 months and 2 partial responses that lasted 13 months and 14 months. Responses were observed in patients with M1a disease and in patients with M1c disease. Sixteen patients had stable disease (15 patients progressed). The median progression-free survival (PFS) was 5.3 months (95% confidence interval [CI], 3.7-7.5 months). The probability of PFS at 6 months was 0.52 (95% CI, 0.33-0.67). Among 38 enrolled patients, 16 patients remained alive at a median follow-up of 6.7 months (range, 1.9-36.1 months). The median overall survival (OS) was 12.1 months (95% CI, 9.1-16.4 months), and the probability of 12-month OS was 0.54 (95% CI, 0.34-0.70 months). The current results indicated that it is safe to administer HD IL-2 sequentially with temozolomide and that this combination has lower toxicity than previously used concurrent biochemotherapy regimens. However, The ORR and the durability of responses with this combination did not exceed those of single-agent HD IL-2.

  • Article: Phase I study of recombinant interleukin-21 in patients with metastatic melanoma and renal cell carcinoma.
    [show abstract] [hide abstract]
    ABSTRACT: A phase I study of patients with metastatic malignant melanoma (MM) and renal cell carcinoma (RCC) evaluated the safety and maximum tolerated dose (MTD), pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of recombinant human interleukin-21 (rIL-21). Patients who had one or fewer prior systemic treatments for metastatic MM or RCC were treated with rIL-21 administered for two 5-day cycles on days 1 through 5 and 15 through 19 of a treatment course; rIL-21 was administered by rapid intravenous infusion in an outpatient setting. Cohorts of patients received doses ranging from 3 to 100 microg/kg/dose, and an expanded cohort was treated at the MTD. Patients with stable disease (SD) or better could receive additional treatment cycles. Forty-three patients were treated (24 MM; 19 RCC), including 28 in the expanded cohort. Dose-limiting toxicities consisted primarily of transient grade 3 laboratory abnormalities. The MTD was estimated to be 30 microg/kg. The most common adverse events included flu-like symptoms, pruritus, and rash. Twelve patients received up to five additional two-cycle courses of treatment without cumulative toxicity, except for one patient with reversible grade 4 hepatotoxicity. Serum concentrations of rIL-21 increased in a dose-proportional manner. Dose-dependent increases in soluble CD25 reflected lymphocyte activation. Antitumor activity was observed in both MM (one complete response and 11 SD) and RCC (four partial responses, 13 SD). Outpatient therapy with rIL-21 at 30 microg/kg was well tolerated, had dose-dependent pharmacokinetics and pharmacodynamics, and was associated with antitumor activity in patients with MM and RCC.

  • Article: A phase II trial of doxorubicin and interferon alpha 2b in advanced, non-medullary thyroid cancer.
    [show abstract] [hide abstract]
    ABSTRACT: The combination of doxorubicin and interferon alpha is supported by preclinical data. We sought to evaluate the efficacy of this combination in patients with advanced thyroid cancer. Patients with locally recurrent or metastatic, radioiodine- refractory thyroid cancer, excluding medullary carcinoma, were treated with interferon alpha-2b 12 million units/m2 subcutaneously on days 1-5 and doxorubicin 40 mg/m2 intravenously, on day 3, every 28 days. 17 patients, 15 with well differentiated and 2 with anaplastic thyroid carcinoma, were enrolled; median age was 69 years. Three patients had received radiation plus low dose doxorubicin previously. In 16 patients assessable for response, 1 patient (6%), who had follicular carcinoma, achieved a partial response and 10 patients (62.5%) stable disease as best response. Median time to progression was 5.9 months and median overall survival 26.4 months. In 14 evaluable patients, 5 (36%) had a thyroglobulin response (30% or more reduction in serum levels). Grade 3/4 neutropenia occurred in 76% of patients and neutropenic fever in 24%. Other grade 3/4 adverse events included fatigue (41%), rigors (18%), fever (6%), nausea/vomiting (29%), anorexia (29%), stomatitis (24%), vision disturbances (18%), neuropathy (18%), and hyponatremia (6%). One patient developed heart failure. Doxorubicin and interferon alpha was associated with considerable toxicities but modest antitumor activity in patients with advanced, non-medullary thyroid cancer.

  • Article: Safety and efficacy of arsenic trioxide for patients with advanced metastatic melanoma.
    [show abstract] [hide abstract]
    ABSTRACT: Arsenic trioxide (ATO) cytotoxicity and apoptosis induction has been demonstrated with numerous cancer cell lines, including human melanoma. A second-line, phase 2, single-arm study of ATO was conducted in patients with inoperable American Joint Committee on Cancer (AJCC) stage IV melanoma. One cycle consisted of a loading dose of 0.32 mg/kg/day for 4 days in Week 1, followed by 0.25 mg/kg/day twice per week for 6 weeks, followed by 1 week of rest, at which time response assessment was performed. Twenty-one patients (median age, 63.8 years) were accrued. All had stage IV melanoma including M1a (2 patients), M1b (6 patients), and M1c (13 patients) disease. One patient had metastatic choroidal melanoma and 20 patients had cutaneous melanoma. Twenty patients had received prior therapy. Possible treatment-related grade 3 of 4 toxicities (using the National Cancer Institute Common Toxicity Criteria) included 1 case of idiopathic thrombocytopenic purpura and 1 case of elevated lactate dehydrogenase. Four patients did not complete the first cycle of therapy and were not evaluable for response. Among 17 evaluable patients, 1 patient (6%; 95% confidence interval [95% CI], 0-29%) achieved a partial response lasting 7 months, and 10 patients (59%) had disease stabilization after at least 1 cycle, but all eventually developed disease progression. The median time to disease progression was 17 weeks (95% CI, 11-38 weeks) and the median survival was 13 months (95% CI, 12-26 months). ATO as tested in the current trial was found to be well tolerated and had limited activity in patients with metastatic melanoma. The application of this agent in combination with either chemotherapy or agents that target recognized critical signaling and antiapoptotic pathways of melanoma has not yet been performed.

  • Article: Long-term results of a phase III randomized trial of postoperative radiotherapy with or without carboplatin in patients with high-risk head and neck cancer.
    [show abstract] [hide abstract]
    ABSTRACT: The role of postoperative radiotherapy and carboplatin in squamous cell carcinoma of the head and neck (SCCHN) has not been established. Patients with macroscopically resected stage III/IV SCCHN with high-risk pathologic features (> or =3 lymph nodes, extracapsular extension, perineural or angiolymphatic invasion, or involved margins) were randomized to receive postoperative radiotherapy alone (arm A) or the same radiotherapy plus carboplatin 100 mg/m intravenously once weekly during radiation (arm B). The primary endpoint was 2-year disease-free survival. Seventy-six patients were randomized, of whom 72 were eligible and analyzable (36 in each arm). The study was prematurely closed because of slow accrual. With a median follow-up of 5.3 years, the disease-free survival at 2 and 5 years was 71% and 53% in arm B versus 58% (P = .27) and 49% (P = .72) in arm A. The overall survival at 2 and 5 years was 74% and 47% in arm B versus 51% (P = .04) and 41% (P = .61) in arm A. Serious toxicities were infrequent in both arms. We could not demonstrate a benefit with the addition of carboplatin to postoperative radiotherapy, possibly because of insufficient sample size.

  • Article: Durable complete responses with high-dose bolus interleukin-2 in patients with metastatic melanoma who have experienced progression after biochemotherapy.
    [show abstract] [hide abstract]
    ABSTRACT: We conducted a phase II trial of high-dose bolus (HDB) interleukin-2 (IL-2) in patients with metastatic melanoma who had experienced progression after biochemotherapy (BCT). Eligible patients had experienced progression on or after BCT (cisplatin, vinblastine, dacarbazine, IL-2 9 MU/m(2)/d for 4 days, and interferon alfa-2b). HDB IL-2 was administered at 600,000 U/kg per dose for a maximum of 14 doses per cycle with a 1-week rest period between cycles. Stable or responding patients were offered an additional course (two cycles) after 6 to 8 weeks. Twenty-six patients (12 men and 14 women), age 28 to 70 years (median, 45 years), have been treated. All but three patients received at least two cycles of HDB IL-2; 10 patients received a second course of therapy. Disease stage was American Joint Committee on Cancer (AJCC) stage M1a (n = 5), M1b (n = 5), and M1c (n = 16). Grade 3 and 4 toxicities included hyperbilirubinemia (n = 10), thrombocytopenia (n = 6), oliguria (n = 3), diarrhea (n = 1), infection (n = 2), and neurologic toxicity (n = 2). Overall response rate was 19.2% (four complete responses, lasting 4, 4, 26+, and 41+ months; and one partial response, lasting 3 months). Five patients (19%) had stable disease lasting 1 to 3 months, but all eventually experienced progression. All four complete responders had AJCC stage M1a disease. At a median follow-up time of 10 months, median survival time was 42 weeks (95% CI, 19.1 to 86.6 weeks), and median progression-free survival time was 10 weeks (95% CI, 8 to 16.1 weeks). An initial response to BCT was not found to be predictive for response to HDB IL-2. HDB IL-2 is active therapy for patients who experience progression on BCT. This observation has implications regarding the importance of dose-intensity for IL-2 therapy.

  • Article: Phase I and pharmacodynamic study of 17-(allylamino)-17-demethoxygeldanamycin in adult patients with refractory advanced cancers.
    [show abstract] [hide abstract]
    ABSTRACT: The primary objective was to establish the dose-limiting toxicity (DLT) and recommended phase II dose of 17-(allylamino)-17-demethoxygeldanamycin (17AAG) given twice a week. Escalating doses of 17AAG were given i.v. to cohorts of three to six patients. Dose levels for schedule A (twice weekly x 3 weeks, every 4 weeks) were 100, 125, 150, 175, and 200 mg/m(2) and for schedule B (twice weekly x 2 weeks, every 3 weeks) were 150, 200, and 250 mg/m(2). Peripheral blood mononuclear cells (PBMC) were collected for assessment of heat shock protein (HSP) 90 and HSP90 client proteins. Forty-four patients were enrolled, 32 on schedule A and 12 on schedule B. On schedule A at 200 mg/m(2), DLTs were seen in two of six patients (one grade 3 thrombocytopenia and one grade 3 abdominal pain). On schedule B, both patients treated at 250 mg/m(2) developed DLT (grade 3 headache with nausea/vomiting). Grade 3/4 toxicities seen in >5% of patients were reversible elevations of liver enzymes (47%), nausea (9%), vomiting (9%), and headache (5%). No objective tumor responses were observed. The only consistent change in PBMC proteins monitored was a 0.8- to 30-fold increase in HSP70 concentrations, but these were not dose dependent. The increase in PBMC HSP70 persisted throughout the entire cycle of treatment but returned to baseline between last 17AAG dose of cycle 1 and first 17AAG dose of cycle 2. The recommended phase II doses of 17AAG are 175 to 200 mg/m(2) when given twice a week and consistently cause elevations in PBMC HSP70.

  • Article: Molecularly targeted therapy for melanoma: current reality and future options.
    [show abstract] [hide abstract]
    ABSTRACT: Effective therapy for melanoma remains an unmet goal, with most traditional therapies representing inadequate trade-offs among the several goals of specificity, efficacy, and toxicity. Targeted molecular therapeutics are tailored to genetic abnormalities that are associated with tumor progression. Modulation of aberrant signaling pathways in cancer cells has the potential to provide more effective and potentially nontoxic therapy for a broad range of cancers, including melanoma. Among the possible targets in melanoma are the Ras-MAPK and PI3K/AKT signal transduction pathways, the proteasome, histone deacetylases, methyltransferases, and melanoma-induced angiogenesis.
