2009 AJCC/UICC Melanoma Staging System
I just returned from the International Conference on melanoma held in
Vienna. Here's the latest on the AJCC/UICC Staging System to be released in
2009. You might want to check out the Website on Individualized Melanoma
Patient Outcome Prediction Tools developed by Seng-jaw Soong et al,
referenced below. It's pretty cool!
The major change in the 2009 AJCC/UICC Melanoma Staging System is the
inclusion of mitotic activity in the primary as important prognostic factor.
Mitotic activity is histologically defined as mitoses/mm2. A mitotic rate
equal of greater than 1/mm2 denotes a melanoma at higher risk for
metastasis. A test version of a program to determine the 5- and 10- year
survival for an individual patient is available on the following Website:
www.melanomaprognosis.org <http://www.melanomaprognosis.org/> . For
patients with localized melanoma (Stage I/II melanoma), the significant
prognostic factors were found to be gender, age, lesion site, tumor
thickness, and ulceration and these are included in the predictive model.
For patients with regional metastasis (Stage III melanoma), the significant
factors were the same, with the added factors of tumor burden and number of
nodes involved with melanoma. The Website allows one to insert these
significant prognostic factors for an individual patient and it will use
these factors to report estimated 5- and 10- year survival rates and
confidence intervals.

Report at 2008 ASCO Meeting Indicates Administration of Vaccine as Adjuvant Therapy of Melanoma Is Ineffective And May Be Harmful
EORTC 18961: Post-operative adjuvant ganglioside GM2-KLH21 vaccination treatment vs observation in stage II (T3-T4N0M0) melanoma: 2nd interim analysis led to an early disclosure of the results.

Abstract
Background: EORTC 18961 assessed in the largest adjuvant phase III trial to date in stage II melanoma the efficacy and toxicity of Ganglioside GM2-KLH21 Vaccination (VAC) Treatment vs Observation (OBS).
Methods
Patients (Pts)\ were observed or received vaccine sc once weekly week 1-4, every 3 months from week 12 for first 2 years and every 6 months during third year (total of 14 vaccinations).
Stratification Factors for Randomization
Breslow thickness, ulceration, being staged yes vs no by Sentinel Node (SNLD) or Elective Lymph Node Dissection (ELND), sex and institution.
Relapse-free survival (RFS) was the primary endpoint; Distant metastasis-free survival (DMFS) and overall survival (OS) were the prespecified secondary endpoints.
Intent-to-treat analysis was performed.
Results
- Between March 2002 and Dec. 2005, 1,314 pts entered the trial.
- Patient demographics showed perfect balance for prognostic factors.
- The 2nd interim analysis was performed when 267 RFS events were reported, i.e. 67% of the total number required at final analysis.
- Median follow-up was 1.8 years.
Similar Treatment Differences
- Obtained in lympnhnode-staged (N=644) or non-staged (N=670) patients.
- Grade 3 - toxicities occurred in < 2%.(VAC) and in < 1% (OBS).
- Grade 2 - toxicities comprised fatigue (15% vs 3%), fever (9% vs 1%), nausea (3% vs 1%).
- Local grade 3 - toxicity occurred in 4 % (VAC).
- The EORTC IDMC reviewed both safety and efficacy data.
- For the primary endpoint, RFS, the criteria for stopping for futility were met.
- For DMFS and OS, the results pointed in the direction of a detrimental effect of the vaccine.
Conclusions
Adjuvant GM2-KLH21 vaccination is ineffective and could even be detrimental in stage II melanoma patients.

Recall of GM-CSF
The following was written by Linda Pilkington:
"German powerhouse Bayer is to pull a formulation of its anti-infective Leukine (sargramostim) from the USA following a spike in the number of adverse events reported, particularly fainting and hypotension.
Bayer says that the rise in AEs corresponds to a formulation change to include edetate disodium, a chelator that is approved separately in the USA as an emergency treatment to combat high levels of calcium in the blood or heart rhythm problems following digitalis poisoning.
The firm says it now plans to reformulate the 500mcg vial - the only one to include EDTA - and will open a special access programme to enable patients with life threatening conditions preferential treatment using the 250mcg vial, which does not contain the substance in question.
Leukine is a growth factor designed to boost the immune system and combat infections in AML and transplantation patients."
Full details can be found at Bayer's press release.
