This study was performed to examine if commonly recorded parameters are of prognostic importance for patients with squamous cell carcinoma of the anal canal. A total of 77 patients received combined chemoradiotherapy and were followed at regular intervals after treatment. Age, sex, performance status, tumour stage, histopathological differentiation and grade, were not found to be of prognostic importance. Most blood tests did not correlate with prognosis, although elevated serum alkaline phosphatase (ALP) and lactate dehydrogenase (LD) proved to be unfavourable prognostic factors. In the present study serum ALP and LD were the only parameters that significantly correlated with development of distant metastases during follow-up.

We examined two recently described cytokeratin markers, CYFRA 21-1 (cytokeratin fragment recognized by KS 19-1 and BM 19-21 antibodies) and TPS (specific M3 epitope of the tissue polypeptide antigen), in 405 lung cancer patients (91 small-cell and 314 non-small-cell lung cancers) and 59 patients presenting with nonmalignant pulmonary disease. Sensitivity-specificity relationship, as analyzed by receiver operating characteristic curves, demonstrated a higher accuracy of CYFRA 21-1 in comparison with TPS in both small-cell and non-small-cell lung cancers. Thresholds of 3.6 ng/ml and 140 U/L for CYFRA 21-1 and TPS respectively gave a 90% to 95% specificity. Sensitivity of CYFRA 21-1 was the highest in squamous-cell carcinomas (0.61) and the lowest in small-cell lung cancers (0.36), whereas sensitivity of TPS did not vary significantly according to histology (overall sensitivity, 0.40). In non-small-cell lung cancers, both serum CYFRA 21-1 and serum TPS distributions varied significantly according to Mountain's stage of the disease, nodal status, tumor status, and performance status, inasmuch as the worse each above-mentioned variable became, the higher the median and interquartile serum marker level was. Neither CYFRA 21-1 nor TPS was able to accurately discriminate between stage IIIa (marginally resectable) and stage IIIb (unresectable) non-small-cell lung cancers, however. In both small-cell and non-small-cell lung cancers, univariate survival analyses demonstrated that either a CYFRA 21-1 level over 3.6 ng/ml or a TPS level over 140 U/L significantly indicated a poor survival rate. In the whole population, taking into account other significant variables, Cox's model analysis demonstrated that a poor performance index, an advanced stage of the disease, the presence of metastases, elevated serum lactate dehydrogenase, and high serum CYFRA 21-1 (odds ratio, 1.74; 95% confidence interval, [1.33-2.27] were independent prognostic variables. We concluded that CYFRA 21-1 is a significant determinant of survival. Other applications of cytokeratin markers in lung cancer are still limited.

Remarkable progress has been made in the treatment of osteosarcoma in the past two decades as a result of the development of effective adjuvant chemotherapy. However, the prognosis is poor in patients with early lung metastases. We review the lactate dehydrogenase release prognostic factor in the development of early lung metastases. This is a retrospective study. Eighteen patients with osteosarcoma were divided in two groups: Group A, patients with normal lactate dehydrogenase and Group B, patients with elevated lactate dehydrogenase. A univaried analysis was established. Ten patients (55%) had elevated levels of lactate dehydrogenase at diagnosis; nine of these patients developed lung metastases in the first twelve months. The difference in patients with normal levels of lactate dehydrogenase was significant (p: 0.02). The value of lactate dehydrogenase as an isolated single factor is limited. It is necessary to consider the tumoral volume, the patient's age and the histologic subtype in the prognosis of these patients, to predict the early development of pulmonary metastatic disease.

Pancreatolblastomas are rare embryonal malignancies in childhood. We report a 3-year-old girl with a tumor of the head of pancreas. Staging by bone scintigraphy and CT scans of abdomen and chest did not show evidence of metastatic disease. Tumor markers showed elevated levels of alpha-1 fetoprotein (64 ng/ml; normal 0-10 ng/ml) and lactate dehydrogenase (423 U/l; normal range below 300 U/l). The tumor was macroscopically completely removed by local resection. Postoperative tumor grading was pT1, NO, MO. The child recovered very soon after surgery without severe complications. Tumor markers dropped to normal values, indicating complete remission (follow-up time 12 months). According to the biological growth characteristics of pancreatoblastomas and to the literature, localized and non-metastatic tumors should be completely resected without radical pancreatoduodenectomy and without adjuvant chemotherapy. This is the most conservative therapy with a good prognosis. However, metastatic disease, primarily inoperable conditions or local relapses are indications for chemotherapy combined with radiotherapy and followed by resection of the tumor. At present, the prognosis of such cases is rather poor.

We investigated the clinical relevance of doubling time (DT) of serum laboratory data obtained in routine clinical examination of patients with primary bone and soft tissue tumors, in comparison with major clinical and pathological parameters (age at presentation, sex, tumor size, location, clinical stage and histologic grade) by uni- and multivariate analyses. In 64 patients with primary bone and soft tissue tumors (primary bone tumors: 39, primary soft tissue tumors: 25) and 68 cancer patients, the pretreatment DT values of serum C-reactive protein (CRP), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), calcium (Ca), phosphate (P) levels were measured, as well as the erythrocyte sedimentation rate (ESR: mm/60 min); these values were then compared with overall survival, local recurrence-free survival and metastasis-free survival. Only DT of CRP and ALP (CRP-DT, ALP-DT) were found to be correlated with disease outcome in patients with primary bone and soft tissue tumors. In cancer patients, only CRP-DT showed a relation with clinical stage and histologic grade, but the ALP-DT in patients with bone metastasis was significantly shorter than that in patients with metastases at other sites or in those with no metastasis. Among all tumor patients, those with bone metastasis showed the shortest ALP-DT compared with those with lung, liver and brain metastasis. Univariate analysis showed that shorter CRP-DT and ALP-DT are associated with poor overall survival, and the development of local recurrence and metastasis. These findings suggest that pretreatment CRP- and ALP-DT could be additional prognostic parameters for disease outcome in patients with primary malignant bone and soft tissue tumors. However, in multivariate analysis, only ALP-DT, but not CRP-DT, was an independent prognostic parameter for these disease outcomes.

Serum lactic dehydrogenase (LDH) levels of 465 patients with nasopharyngeal carcinoma (NPC) were assayed retrospectively. Four cohorts were selected in order to investigate the enzymes: 1) stage IV disease (118 cases) with pretreatment measurement, 2) relapse cases (159 cases) with pretreatment measurements, 3) no evidence of disease (217 cases) with spotting or serial measurements, and 4) monitoring of response to cytotoxic chemotherapy (34 cases). Higher serum LDH levels and more cases with elevated values were found in metastatic disease, especially relapse cases with liver and/or multiple organ site metastases. Serum LDH levels in locoregional disease were rarely found to be greater than two times the normal level. The value of serial serum LDH measurement for detecting disease relapse in the follow-up of patients with NPC is limited. Twelve percent of cases with no evidence of disease demonstrated elevation in serum levels. Serum LDH levels were found to correlate with the clinical responsiveness to systemic chemotherapy. Cases with normal serum LDH before treatment had a better chance of survival than those with elevated levels (median: 53 vs. 10 months, p = 0.008).

Mucoepidermoid carcinomas are malignant neoplasms that rarely involve the skin. Composed of both mucus-secreting cells and epidermoid-type cells in various proportions, mucoepidermoid carcinomas occur most commonly in salivary glands. In this case report, we describe a high-grade mucoepidermoid carcinoma with cutaneous involvement. Although this patient was referred for Mohs' micrographic surgery, further evaluation showed either direct or metastatic extension from the parotid gland to skin and distant metastases to the lung and bone. Despite extensive bone involvement, serum levels of ionized calcium, phosphorus, and lactate dehydrogenase remained normal. In view of the widespread metastases, the treatment plan was altered to radiotherapy and chemotherapy instead of surgery. Instructive lessons from this case include the recognition by dermatologists of this rare entity, the importance of a detailed history and complete evaluation of the patient before determining appropriate therapy, and the necessity of individualizing diagnostic tests to a particular patient.

The skeleton is the most common organ to be affected by metastatic cancer, and tumors arising from the breast, prostate, thyroid, lung, and kidney possess a special propensity to spread to bone. Breast carcinoma, the most prevalent malignancy, causes the greatest morbidity. Of great clinical importance is the observation that metastatic bone disease may remain confined to the skeleton. In these patients, the decline in quality of life and eventual death is due almost entirely to skeletal complications and their subsequent treatment. Bone pain is the most common complication of metastatic bone disease, resulting from structural damage, periosteal irritation, and nerve entrapment. Recent evidence suggests that pain caused by bone metastasis may also be related to the rate of bone resorption. Hypercalcemia occurs in 5-10% of all patients with advanced cancer but is most common in patients with breast carcinoma, multiple myeloma, and squamous carcinomas of the lung and other primary sites. Pathologic fractures are a relatively late complication of bone involvement. The clinical courses of breast and prostate carcinoma are relatively long, with a median survival of 2-3 years. For patients with breast carcinoma, good prognostic factors for survival after the development of bone metastases are good histologic grade, positive estrogen receptor status, bone disease at initial presentation, a long disease free interval, and increasing age. In addition, patients with disease that remains confined to the skeleton have a better prognosis than those with subsequent visceral involvement. For patients with prostate carcinoma, adverse prognostic features include poor performance status, involvement of the appendicular skeleton and visceral involvement, whereas for patients with multiple myeloma, the levels of serum beta2-microglobulin and lactate dehydrogenase and the immunologic phenotype are the most important factors. These prognostic factors may be useful in planning the rational use of bisphosphonates in the treatment of advanced cancer.

The aim of this study was to evaluate multimodal chemotherapy and radiotherapy in patients with Ewing's sarcoma. 142 (74 male, 68 female) patients were entered into the ET-1 study between 1978 and 1986. They were treated with vincristine, doxorubicin, actinomycin D, and cyclophosphamide with radiotherapy plus or minus surgery to the primary tumour. Of the 120 who had no metastases at diagnosis, 45 remain alive with a median follow-up of 11.2 years. Only 2 of those with metastases at diagnosis remain alive. The major prognostic factor was site of disease, but age and serum lactic dehydrogenase at diagnosis also had an influence on outcome. 45 of the 61 patients who survived 4 years or more had late effects documented. The type and extent were dependent on tumour site, type of local therapy, volume and dose of radiotherapy. 4 patients had second malignancies. Prospects for long-term survival have improved in patients treated for Ewing's sarcoma. However, late sequelae are present in the majority of patients.

The records of 116 patients from a single center (1970-1993) with newly diagnosed Ewing's sarcoma or primitive neuroectodermal tumor were reviewed retrospectively. The aim of this study was to ascertain the impact of pretreatment variables on disease-free survival. Median age was 14 years (range 1-34). Twenty patients presented with metastatic disease. Treatment consisted of systemic multiagent chemotherapy plus local irradiation (39%), wide resection (22%), or both (35%). Median potential follow-up was 10.7 years (range 2-26). Three patients developed second malignancies (1 breast carcinoma, 2 acute myeloid leukemias). Median time to relapse was 24 months (range 3-143). The actuarial disease-free survival was 37.4% at 5 years, 33.3% at 10 years and 27.8% at 15 years. Neoadjuvant chemotherapy and a therapy-induced tumor necrosis > or = 90% were associated with a better outcome. Patients undergoing surgical resection had a superior disease-free survival than those treated without surgery (45 vs. 18% at 10 years, p = 0.0009). Multiple regression analysis showed that raised serum lactate dehydrogenase levels (p < 0.001), hypoalbuminemia (p = 0.001) and distant metastases at diagnosis (p = 0.03) were independent adverse prognostic factors. In conclusion, one third of patients with Ewing's sarcoma become long-term survivors with combined modality treatment. Late relapses and second neoplasms are of concern. Prognostic factors should be considered in the selection of therapy, and the value of serum albumin warrants confirmatory studies.
