CEA, SCC and CYFRA 21-1 were measured in samples of serum coming from 105 'Non small cell lung cancer' (NSCLC) patients. The present study has been carried out to compare these markers, to analyse their prognostic significance and to determine the best combination of tumor markers. The median value and interquartile range were: CYFRA 21-1: 2,3 ng/ml, CEA: 3,7 ng/ml, SCC: 1,2 ng/ml. CEA demonstrated higher values in adenocarcinomas (P = 0.04). SCC and CYFRA 21-1 were comparable in the different histologic groups. CYFRA 21-1 and CEA values were dependant on tumor stage. Advanced tumors (T3 and T4) demonstrated higher serum CYFRA 21-1 level (P = 0.0006). CYFRA 21-1 was higher than 3,3 ng/ml in 36% of patients. CEA was higher than 5 ng/ml in 38% of patients and SCC was higher than 2 ng/ml in 27% of patients. Patients with a high CEA and CYFRA21-1 serum level had a shorter survival than those with a normal serum level. In a Cox regression analysis four variables (TNM stage, age, CYFRA 21-1 and CEA level) were found to be significant in the prediction of survival; CYFRA 21-1 level had the lowest P value (P = 0.0002). The current study suggests the use of a combination of CEA and CYFRA 21-1 in the clinical care of NSCLC.

This survey describes potential clinical applications of the tumour markers CYFRA 21-1, SCC antigen, NSE, and CEA in patients with lung cancer. Due to the rather low prevalence of bronchogenic carcinoma in the general public and the limited diagnostic accuracy, currently available tumour markers are unsuitable for the screening of asymptomatic individuals. All studies performed so far in patients with histologically confirmed NSCLC, agree that the best performance characteristics, in terms of sensitivity and specificity, were obtained with the CYFRA 21-1 test (sensitivity: 40-66%, specificity: 95% versus patients with benign pulmonary disorders) while NSE was found to be the marker of first choice in patients with SCLC (sensitivity: 77-85%). For diagnostic purpose, the value of tumour markers must be compared with the efficiency of standard clinical methods including imaging techniques and cytopathological examinations (detection rates: sputum cytology: 40-70%, biopsy at bronchoscopy in central tumours: 95-98%, biopsy at bronchoscopy + bronchial washing + thin needle aspiration in peripheral tumours: 85%). These figures show that the diagnostic yield of cytopathological examinations by far exceeds that of tumour markers. In addition, these investigations supply with histology and give informations on the T-stage (bronchoscopy). Tumour markers, however, may be used for diagnosis in advanced stages in which patients are very often not eligible for extensive investigations due to their performance status. In the differential diagnosis between NSCLC and SCLC a combination of CYFRA 21-1 and NSE was claimed to be helpful. It was demonstrated that 97% of patients could be correctly classified. NSE was shown to be useful to distinguish SCLC from malignant lymphoma, both the Hodgkin's (rate of false-positive elevations: 6.5%) and the non-Hodgkin's (rate of false positive elevations: 22.4%) types. By applying a cut-off point of NSE assays of 21.9 ng/ml corresponding to a 95% specificity versus the lymphoma group, SCLC is still indicated by elevated NSE levels with a sensitivity of 57.7%. Although a positive correlation of marker concentrations with increasing anatomical tumour extent could be demonstrated, the markers cannot be used for staging purposes due to a considerable overlap of marker levels between the individual stages. CYFRA 21-1 was shown to be unable to differentiate between operable (TNM I-IIIa) and inoperable (TNM IIIb/IV) NSCLC patients. The latter were identified with a detection rate of only 17% by the CYFRA 21-1 test (specificity 95% versus operable patients, cut-off point 20 ng/ml). Pretreatment-measured tumour markers, in particular CYFRA 21-1, were shown to provide prognostic information for the overall survival. The negative prognostic effect of CYFRA-21-1 was independent of classical prognostic markers such as performance status and tumour extent. There are several potential applications of serially-assessed tumour markers for disease monitoring of patients under therapy. In SCLC, increasing NSE levels within the remission phase were demonstrated to be strongly suggestive of tumour recurrence. This finding should give rise to further diagnostic procedures. NSE, however, was not able to differentiate between partial and complete remission since, in both cases, NSE levels dropped to the normal range; thus, NSE cannot replace clinical response evaluations. In NSCLC, it was found that curative surgery resulted in a significant drop of preoperatively elevated CYFRA 21-1 or SCC antigen levels down to the normal range. Although rising SCC antigen levels in the postoperative surveillance of patients with squamous cell carcinoma indicated very early tumour relapse, these results are of minor clinical utility due to the absence of curative therapy. Serial measurement of CYFRA 21-1 during chemotherapy in patients with inoperable squamous cell carcinoma has shown that there is a concordance of 74% between the course of the m

The authors studied the influence on survival of 21 clinical, anatomical, haematological and biochemical factors evaluated, at diagnosis, of 411 patients (pts) with advanced Non Small Cell Lung Cancer (NSCLC) followed in our department between 1984 and 1990. Most of the patients were male (347--84.4%) and only 64 (15.6%) were females. Median age was 62 years, but was slightly higher in females. Only 34 patients were aged under 45 years. Squamous cell carcinoma (215 pts--52%) and adenocarcinoma (152 pts--37%) were the most frequent histologic types. Performance status was poor--only 103 (25%) continued active; 120 (29%) spent at least half of the time in bed; 188 (46%) were severely limited. After staging, 179 (44%) presented locally advanced disease (stage IIIB) and 232 (56%) metastatic dissemination (stage IV). Therapy was defined by the oncologic group according to individual characteristics and based on clinical grounds. Anti-neoplastic therapy was performed in 225 (55%), chemotherapy alone in 121 (30%), radiation therapy alone in 67 (16%), and sequential combined treatment (chemotherapy and thoracic radiation) in 37 (9%). Until 1987, the main chemotherapy regimen was MACC (Metrotrexate + Adriamycine + Cyclophosphamide + Lomustin), afterwards VP(M) (Cisplatin + Vimblastin + Mitomycine). Radiation therapy was performed using Co60, 2 Gy/day, 5 days a week, for 4 weeks (approximately 45 Gy total). The response rate was poor--four complete responses (2%), 42 (19%) partial responses. The overall median survival was 4.3 months and only 5% of patients were alive after 18 months of follow up. Prognostic importance of each characteristic studied was initially done by unifactorial analysis, followed by multifactorial analysis according to two methods: Cox proportional hazards model and recursive partitioning amalgamation--RECPAM. Regardless of the method used, the main determinants of survival were found to be performance status (Zubrod), weight loss and serum albumin. Other factors such as the staging (presence or absence of metastasis), lymphocytes, lactic dehydrogenase, and hoarseness were also significant. It is noteworthy that age and histological type were irrelevant; sex and hoarseness only proved important when integrated within a multifactorial model. The overall prognostic evaluation and therapeutic decision of advanced NSCLC patients could be improved by combining the prognostic value of TNM with that of performance status, weight loss and serum albumin. These prognostic guidelines must be taken into account when designing new clinical trials.

Patients with SCLC should have a complete history and physical examination with particular attention paid to symptoms and signs of extensive disease and paraneoplastic syndromes. Hematology and biochemistry should be obtained at the initial assessment. A chest radiograph will usually have been performed prior to diagnosis. Further imaging should then be done to determine if the patient has limited or extensive disease. In the nonprotocol setting, extensive radiologic investigations are not required once a site of metastatic disease has been identified. If symptoms or signs are present to indicate a site of extensive disease, then this should direct the next test. In the absence of any specific findings then either bone scan or abdominal imaging with either US or CT scanning may be done based on the roughly equal likelihood of metastatic disease in liver or bone. Because a bone scan is less expensive, it is often the next test selected. If the bone scan is negative, abdominal imaging should then be performed, followed by brain CT scan. If these investigations are negative, the next study should be a thoracic CT scan. Bone marrow examination is probably unnecessary in the nonprotocol setting unless serum LDH levels are elevated. In the setting of a clinical trial, complete staging should be done and even more precise staging using the TNM system should be considered based on the improved survival of patients with proven stage I disease. Using more precise staging will allow accurate comparisons of clinical trials and eliminate or minimize the question of patient selection. Surgical staging with mediastinoscopy may come to have a role in accurately determining stage I or II disease.

Lung cancer is a worldwide problem and in many countires it is the most lethal malignancy. Because relapse is frequent after resection of non small cell lung cancer, an urgent need exists to define prognostic factors which could help in choosing the best therapeutic approach. We performed immunohistochemistry on 60 formalin-fixed paraffin-embedded non small cell lung cancer specimens in order to evaluate the frequency of cyclin D1 overexpression, and to relate it to the degree of malignancy of these tumors and to the overall survival time of the patients. All specimens were positive for cyclin D1 immunostaining. We found cyclin D1 overexpression in 30 (50%) of our specimens, with no significant difference among the different histological types. Cyclin D1 overexpression correlates in a statistical manner with short-term patient survival. Mantel-Cox analysis of these data generated a significant P value = 0.003. The mean survival time and the five-year survival rate also differed statistically. We did not find any statistically significant correlation between cyclin D1 overexpression and histological grading, tumor stage or TNM status. We concluded that cyclin D1 overexpression in 30 patients is a frequent event in non small cell lung cancer pathogenesis and may have prognostic relevance.

Results of surgical treatment for small cell lung cancer were reviewed to confirm the role of surgery. Most of the surgical therapy was performed with post or pre-operative chemotherapy. Clinical staging of small cell lung cancer treated by chemotherapy and/or radiotherapy has not been classified according to the TNM staging system, which made it difficult to compare the results of surgical treatment with non-surgical treatment in detail. Results of surgical treatment for small cell lung cancer according to the TNM staging system reported in 1990's were as follows. For stage I diseases, nearly all the patients underwent complete resection followed by standard chemotherapy. Five-year survival rates were over 50% in most of the reports. Surgical resection followed by chemotherapy is the standard therapy for stage I diseases. For stage II diseases, the greater part of patients were treated by complete resection followed by chemotherapy, which resulted in five-year survival rates of 28-35%. Nationwide statistics on surgical resection for small cell lung cancer in Japan revealed that the stage I and II diseases are actually resected, and the five-year survival rate reached 37%. Thus, surgery followed by chemotherapy for stage II diseases is becoming the standard therapy. For stage IIIA diseases, surgical resection after chemotherapy followed by chemotherapy and/or radiotherapy has been tried investigationally. The five-year survival rates of 16-48% in these patients suggests the increasing role of surgery for these patients.

Thanks to the knowledge of pretherapeutic factors able to explain the evolution of a disease, the clinician gets guidelines for the choice of a treatment for an individual patient and, on a population level, he receives important information for the design and interpretation of clinical studies. Our purpose, here, is to review the "classical" prognostic factors, defined as factors usable in a daily clinical practice, for survival in a population of patients with a stage III and small cell lung cancer. The first variable to be taken into account is the operability status, highly correlated to the TNM substage IIIA or IIIB. For patients who will go to surgery, relying on the literature, we don't have any definite prognostic factor. Some data suggest that histology other than squamous cell or adenocarcinoma, male sex, age greater than 65 years, low performance status or N2 disease are unfavorable characteristics. For patients who will not benefit from surgery, a good performance index is a definitely recognized favorable feature. Prediction of the prognosis could be improved by the inclusion in a model of the TNM substage, the sex, the weight loss, the LDH level in the serum. Other biological factors like hemoglobinemia or albuminemia have to be confirmed. Generally, we need prospective studies designed to validate, on large series of patients, prognostic variables or indexes on a multivariate basis.

Advanced non-small cell lung cancer (NSCLC) denotes those of TNM stage III and IV. NSCLC has its specific characteristics in respect of oncological behaviour, molecular biology, sensitivity to chemotherapy (CT) and radiotherapy (RT), and requires different therapeutic strategies in comparison with small cell lung cancer. The therapies include: (1) surgery in combination with new effective drugs is resulted in improved RR from 15% a decade ago to 40-60% today. Cisplatin (C-DDP) is the most attractive drug in the treatment of NSCLC, in lengthening the life-span of Stage IV NSCLC patients and as an indispensable sensitizer in RT. Taxinol, Gemcitabine (GEM), Navelbine (NVB), Edatrexate (ETX), CPT-11 and high dose Epirubicin (EPI HD) are recommended as new effective drugs. Response rates recently reported for the combination CT with the drugs mentioned above for NSCLC are from 30-65%, and with 8-42 weeks of MST. Induction or neoadjuvant therapies for advanced NSCLC, with 40-69% of RR, 25-29% of complete resection rate, 8-34% of CR and 17-45% of one year SR are reviewed. Eight random studies comparing MST between CT with C-DDP and best supportive care for NSCLC are statistically significant. (2) RT for Stage III NSCLC with 2 year and 5 year survivals of 20 and 5% respectively. Although such outcome is hardly acceptable, RT sensitizer, modified RT techniques and chemoradiotherapy (CRT) are imperative to improve the effect of RT in advanced NSCLC. Clinical literature suggest that CRT is better than RT, though without marked difference. Further studies and sufficient follow-up are necessary to judge the efficacy in terms of long-term survival and toxic reaction. (3) Biological therapy: gene therapy of NSCLC is still in the experimental and developmental stage. Of biological response modifier (BRM), alpha IFN in 11 cases of NSCLC with RR of 9% and MST of 14 months, IL-2 and LAK cell treatment in 11 cases with RR of 9% and MST of 18 months are reported. Instillation of BRM such as IL-2 or alpha-IFN into the pleura after drainage of cancerous effusion has been reported as the most effective for those whose RR is of 80-90% and the clinical response time is fairly long. Hematological cytokine as a protective adjuvant therapy against CT/RT toxicity makes high dose of CT possible and raises the response and patient tolerance. In multimodality therapy, it plays an important role to reduce post CT infection and septicemia.

Small cell carcinoma of the bladder is a rare and highly aggressive tumor. We report our experience with 5 consecutive patients treated with systemic chemotherapy and adjuvant radiotherapy. TNM stages were T2N0M0 (1 patient), T3aN0M0 (3 patients) and T3bN1M0 (1 patient). The chemotherapy protocol was the one used with small cell lung cancer patients at our hospital: six cycles of alternating PE/CAV (PE: cisplatin, etoposide; CAV: cyclophosphamide, doxorubicin, vincristine). Cystoscopy was performed after the third cycle. Four out of 5 patients were free of macroscopic disease. The fifth patient had persistent lesions and was treated by cystectomy. This patient developed a local-regional recurrence 4 months later and died shortly afterwards. Four patients completed the planned six cycles. Cystoscopy with bladder biopsy was then performed on each, and all had complete remission. They were treated with external radiotherapy (45 Gy pelvis, 60 Gy bladder). One patient had invasive bladder recurrence 12 months later and cystectomy was performed. At the last follow-up 42 months later, he was alive and well. The other 3 patients were alive and free of disease 60, 48 and 27 months after diagnosis, respectively. These results are clearly more favorable than previous reports. Cystectomy might, therefore, be unnecessary in some patients.

The staging procedures for small cell lung cancer do not differ appreciably from those for other forms of lung cancer. For practical purposes, the TNM stages are usually collapsed into a simple binary classification: limited disease and extensive disease. This study was performed to answer the question of whether fluorine-18 labelled 2-deoxy-2-D-glucose positron emission tomography (FDG-PET) imaging permits appropriate work-up (including both primary and follow-up staging) of patients presenting with small cell lung cancer, as compared with currently recommended staging procedures. Thirty-six FDG-PET examinations were performed in 30 patients with histologically proven small cell lung cancer. Twenty-four patients were examined for primary staging while four were imaged for therapy follow-up only. Two patients underwent both primary staging and up to four examinations for therapy follow-up. Static PET imaging was performed according to a standard protocol. Image reconstruction was based on an ordered subset expectation maximization algorithm including post-injection segmented attenuation correction. Results of FDG-PET were compared with those of the sum of other staging procedures. Identical results from FDG-PET and the sum of the other staging procedures were obtained in 23 of 36 examinations (6x limited disease, 12x extensive disease, 5x no evidence of disease). In contrast to the results of conventional staging, FDG-PET indicated extensive disease resulting in an up-staging in seven patients. In one patient in whom there was no evidence for tumour on conventional investigations following treatment, FDG-PET was suggestive of residual viability of the primary tumour. Furthermore, discordant results were observed in five patients with respect to lung, bone, liver and adrenal gland findings, although in these cases the results did not affect staging as limited or extensive disease. Moreover, FDG-PET appeared to be more sensitive for the detection of metastatic mediastinal and hilar lymph nodes and bone metastases. Finally, all findings considered suspicious for tumour involvement on the other staging procedures were also detected by FDG-PET. It is concluded that FDG-PET has potential for use as a simplified staging tool for small cell lung cancer.
