The objective of this study was to identify prognostic factors for survival in patients with advanced oesophageal cancer, who are treated with cisplatin-based combination chemotherapy. We analysed the baseline characteristics of 350 patients who were treated in six consecutive prospective trials with one of the following regimens: cisplatin/etoposide, cisplatin/etoposide/5-fluorouracil, cisplatin/paclitaxel (weekly) and cisplatin/paclitaxel (biweekly). Predictive factors in univariate analyses were further evaluated using multivariate analysis (Cox regression). The median survival of all patients was 9 months. The 1, 2 and 5-year survival rates were 33, 12 and 4%, respectively. The main prognostic factors were found to be WHO performance status (0 or 1 vs 2), lactate dehydrogenase (normal vs elevated), extent of disease (limited disease defined as locoregional irresectable disease or lymph node metastases confined to either the supraclavicular or celiac region vs extensively disseminated disease) in addition to the type of treatment (weekly or biweekly cisplatin/paclitaxel regimen vs 4-weekly cisplatin/etoposide with or without 5-fluorouracil). Although weight loss, liver metastases and alkaline phosphatase were significant prognostic factors in univariate analyses, these factors lost their significance in multivariate analyses. The median survival for patients without any risk factors was 12 months, compared to only 4 months in patients with WHO 2 plus elevated LDH and extensive disease. The performance status, extent of disease, LDH and the addition of paclitaxel to cisplatin are independent prognostic factors in patients with advanced oesophageal cancer, who are treated with cisplatin-based combination chemotherapy.

We evaluated the long-term results obtained in 402 patients with non-metastatic Ewing's sarcoma (ES) of the bone treated in a single institution with adjuvant and neoadjuvant chemotherapies between 1972 and 1992. Multivariate analyses showed male gender, age older than 14 years, high serum lactate dehydrogenase (LDH) level, axial location of the tumour, use of radiotherapy alone as a local treatment, and poor histological response to chemotherapy, to be independent, adverse prognostic factors for event-free survival (EFS). At a mean follow-up of about 18 years (10-30 years), 177 patients (44.0%) remained continuously free of disease, 2 died of doxorubicin-induced cardiotoxicity and 8 developed a second neoplasm (5 died, and 3 are alive and free of disease). 215 patients relapsed with metastases and/or local recurrence: 14 are alive and free of disease, 1 is alive with uncontrolled disease, and 200 died. The overall survival (OS) at real follow-ups of 5-, 10-, 15- and 20-years was 57.2, 49.3, 44.9 and 38.4%, respectively. We conclude that since local or systemic relapses, treatment-complications and second malignancies are more common after 5 years or more from the beginning of treatment; a long-term follow-up is mandatory for patients with ES.

The outcome of treatment and prognostic factors were reviewed in 36 patients who had Ewing's sarcoma of the foot. The tumor was most common in the calcaneus (19 patients) and metatarsals (15 patients). Age, levels of lactate dehydrogenase, degree of anemia, tumor volume, type of surgery, and radiotherapy were not related to prognosis. Females with pain for less than 6 months, fever, high levels of erythrocyte sedimentation rate, and high levels of alkaline phosphatase showed a tendency for a poorer prognosis. The only observed prognostic factors are tumor site and treatment. Patients treated with four-drug neoadjuvant chemotherapy had the best survival. Four patients with metastatic disease at diagnosis died. Fourteen of 32 patients (44%) with localized Ewing's sarcoma were continuously disease-free at an average followup of 7 years.

A completely revised staging system for cutaneous melanoma was implemented in 2003. The changes were validated with a prognostic factors analysis involving 17,600 melanoma patients from prospective databases. This major collaborative study of predicting melanoma outcome was conducted specifically for this project, and the results were used to finalize the criteria for this evidence-based staging system. In fact, this was the largest prognostic factors analysis of prospectively followed melanoma patients ever conducted. Important results that shaped the staging criteria involved both the tumor-node-metastasis (TNM) criteria and stage grouping for all four stages of melanoma. Major changes in the staging include: (1) melanoma thickness and ulceration are the dominant predictors of survival in patients with localized melanoma (Stages I and II); deeper level of invasion (ie, IV and V) was independently associated with reduced survival only in patients with thin or T1 melanomas. (2) The number of metastatic lymph nodes and the tumor burden were the most dominant predictors of survival in patients with Stage III melanoma; patients with metastatic nodes detected by palpation had a shorter survival compared with patients whose nodal metastases were first detected by sentinel node excision of clinically occult or "microscopic" metastases. (3) The site of distant metastases (nonvisceral versus lung versus all other visceral metastatic sites) and the presence of elevated serum lactate dehydrogenase (LDH) were the dominant predictors of outcome in patients with Stage IV or distant metastases. (4) An upstaging was implemented for all patients with Stage I, II, and III disease when a primary melanoma is ulcerated by histopathological criteria. (5) Satellite metastases around a primary melanoma and in-transit metastases were merged into a single staging entity that is grouped into Stage III disease. (6) A new convention was implemented for defining clinical and pathological staging so as to take into account the new staging information gained from lymphatic mapping and sentinel node biopsy.

Neuroendocrine tumors, particularly those of gastrointestinal tract origin, have a predisposition for metastasizing to the liver, causing parenchymal substitution and paraneoplastic syndrome. Lipiodol embolization combined with anticancer drugs is a recent tool in regional therapy. It has been proven that chemoembolization reduces tumor bulk and hormone levels, and that it palliates the symptoms of many patients with liver-dominant neuroendocrine metastases. Beginning in December 1988, ten patients with unresectable and chemotherapy-refractory liver metastatic neuroendocrine tumors were treated with chemoembolization based on a mixture of lipiodol, mitomycin, cisplatin, epirubicin, followed by gelfoam powder and contrast media. Toxicity encountered included: upper right quadrant pain requiring narcotics, elevation of lactate dehydrogenase, alkaline phosphatase, and transaminases. One patient had liver abscess and persistent fever for 2 weeks. We obtained two complete remissions lasting 12 and 34 months and 5 partial remissions. The median survival was 22 months. Four patients had urinary elevation of 5-hydroxyindolacetic acid (5-HIAA). They showed more than a 75% decrease in urinary secretion after treatment. In a patient with transplanted liver we noticed a partial response lasting 7 months. We conclude that chemoembolization will improve the clinical condition of a significant percentage of patients with liver metastases, that future therapy of carcinoid tumors will be based on specific tumor biology and that treatment will be customized for each individual patient combining the use of cytoreductive procedures including radiofrequency ablation, laser treatment and chemoembolization.

A 5-year-old girl presented with a painful abdominal mass. Abdominal magnetic resonance imaging (MRI) showed 3 separate masses. Tumor markers including lactate dehydrogenase (LDH), cancer antigen-125 (CA-125), beta-subunit of human chorionic gonadotropin (beta-hCG) and neuron-specific enolase (NSE) were elevated. At operation, the main tumor arose from the left ovary and was associated with torsion, whereas the other lesions were lymph node metastases. A salpingo-oophorectomy was performed. Histopathologic examination indicated that the tumor was a dysgerminoma. Immunohistochemicallly, the cells were positive for NSE and placental alkaline phosphatase (PALP) but were negative for CA-125, beta-hCG, S-100, glial fibrillary acidic protein, and vimentin. The elevated serum levels of tumor markers improved dramatically after the operation and chemotherapy.

Tumor markers in the serum of cancer patients have an important role in clinical diagnosis and in prognosis, and also in the monitoring of the patients' disease and response to therapy over time. The serum markers currently available for melanoma have only limited clinical use. Those most widely used in clinical applications are S100-beta, melanoma inhibitory activity, and lactate dehydrogenase; there are close correlations between the serum concentrations of these and tumor load. Regular determination of S100-beta and MIA levels during follow-up can therefore be used for early detection of a tumor relapse in melanoma patients, increased serum concentrations of these marker proteins being indicative of tumor growth. Patients with distant metastases from melanoma who present with elevated serum levels of S100-beta, MIA, or LDH have poorer overall survival than do patients whose serum concentrations are within normal ranges. These three markers can also be used to monitor the course of disease and therapy outcome in patients with distant metastases. Since there are no marker proteins for melanoma that are not dependent on tumor load, it is not currently possible to forecast the survival of patients who are tumor free after surgery. Serum markers are also not suitable for screening or for the diagnosis of primary melanomas.

The presence of neuroendocrine (NE) differentiation in the context of predominantly exocrine prostate cancer may play a key role in androgen-independent tumor growth. The prognostic significance of plasma chromogranin A (CgA) was assessed in a series of consecutive prostate cancer patients with hormone-refractory disease. One hundred and eight patients with newly diagnosed hormone-refractory prostate cancer entered the study. Plasma CgA levels and other biochemical parameters, such as serum prostate specific antigen, serum alkaline phosphatase, serum lactate dehydrogenase, serum albumin and hemoglobin concentration, were measured at baseline (i.e. when hormone refractoriness occurred) and their prognostic role was evaluated together with patient performance status, Gleason score (at diagnosis of prostate cancer) and the presence of visceral metastases. Furthermore, plasma CgA was prospectively evaluated in 50 patients undergoing chemotherapy. At baseline, 45 patients (43.3%) showed elevated CgA values. Plasma CgA negatively correlated with survival, either in univariate analysis (P=0.008) or in multivariate analysis, after adjusting for previously mentioned prognostic parameters (P<0.05). In the patient subset undergoing chemotherapy, median CgA (range) values were 13.3 (3.0-141.0) U/l at baseline, 19.1 (3.0-486.0) U/l after 3 months, 20.8 (3.0-702.0) U/l after 6 months and 39.4 (3.0-414.0) U/l after 9 months (P<0.01). The corresponding supranormal rates were 17/50 (34%), 23/50 (46%), 26/50 (52%) and 34/50 (68%) respectively (P<0.005). Elevated plasma CgA levels are frequently observed in prostate cancer patients with hormone-refractory disease and correlate with poor prognosis. NE differentiation in hormone-refractory patients is a time-dependent phenomenon and is not influenced by conventional antineoplastic treatments.

In order to identify factors predictive of central nervous system (CNS) metastasis, we reviewed the histories of 579 patients treated with epirubicin-based chemotherapy for metastatic breast cancer. Statistical analysis included Kaplan-Meier survival plots, Cox's regression analysis and competing risk analysis using the cumulative incidence. Median follow-up-time was 137 months (range 0-183+). In this period, one hundred and twenty-four patients (21.4%) developed CNS metastasis. Lung, liver, and lymph node metastases and oestrogen receptor negative or unknown tumor were predictive as well. However, increased pretreatment lactate dehydrogenase (LDH) concentration in serum above the upper normal limits was the strongest single risk factor and should therefore be measured. The risk of CNS metastasis differed considerably among risk groups. Patients without risk factors had a cumulative incidence on 9%, compared to a cumulative incidence of 42%, when the serum LDH concentration was elevated to more than twice the upper normal limits.

We aimed to create a prognostic model in metastatic melanoma based on independent prognostic factors in 321 patients receiving interleukin-2 (IL-2)-based immunotherapy with a median follow-up time for patients currently alive of 52 months (range 15-189 months). The patients were treated as part of several phase II protocols and the majority received treatment with intermediate dose subcutaneous IL-2 and interferon-alpha. Neutrophil and monocyte counts, lactate dehydrogenase (LDH), number of metastatic sites, location of metastases and performance status were all statistically significant prognostic factors in univariate analyses. Subsequently, a multivariate Cox's regression analysis identified elevated LDH (P<0.001, hazard ratio 2.8), elevated neutrophil counts (P=0.02, hazard ratio 1.4) and a performance status of 2 (P=0.008, hazard ratio 1.6) as independent prognostic factors for poor survival. An elevated monocyte count could replace an elevated neutrophil count. Patients were assigned to one of three risk groups according to the cumulative risk defined as the sum of simplified risk scores of the three independent prognostic factors. Low-, intermediate- and high-risk patients achieved a median survival of 12.6 months (95% confidence interval (CI), 11.4-13.8), 6.0 months (95% CI, 4.8-7.2) and 3.4 months (95% CI, 1.2-5.6), respectively. The low-risk group encompassed the majority of long-term survivors, whereas the patients in the high-risk group with a very poor prognosis should probably not be offered IL-2-based immunotherapy.
