[Value of panendoscopy in assessment of mouth cavity, pharyngeal and laryngeal cancers].
The concept of multiple squamous cell carcinoma in the region of the upper aerodigestive tract was first described over 100 years ago by Billroth. The aim of our study was to assess the incidence of synchronous and metachronous second primary tumours and refine the role of panendoscopy in diagnosing them. The charts of 358 patients presenting for initial treatment of primary squamous cell carcinoma of the upper aerodigestive tract between January 1990 and December 1995 were reviewed. The incidence of second primary tumours was 16.2%, 6.4% being synchronous and 9.8% metachronous. In only 3.1% of all patients was a synchronous tumour clinically silent and only revealed by panendoscopy. Synchronous tumours were most likely to be located in the oral cavity, pharynx or larynx (61%), whereas metachronous second primary tumours were most likely to be located in the lung (57%). Though the incidence of synchronous second primary tumours revealed by routine panendoscopy is low (3%), we still recommend this investigation because it is often necessary for exact assessment of the first primary tumour. Further, it is ideal for training in the use of rigid endoscopy. In our opinion panendoscopy involves minimal time, cost and morbidity.

[Synchronous and metachronous carcinomas of the large intestine].
The authors present their experience relative to 5 patients with multiple carcinomas (synchronous and metachronous) of the large bowel. They underline that full examination of the colon before operation in all patients with primary colorectal cancer is necessary, and they propose a lifelong follow-up program after resection for early detection of multiple carcinomas.

[Postmortem diagnosis of primary malignant tumors in a 10-year patient material].
Dissectional data were analysed of deceased patients due of malignant tumors of the neck-head area, in the authors institute in the last ten years. Besides the fatal primary tumor in 6.1% of the cases there were clinically not, just post mortem diagnosed multiple tumors. The authors advise more thorough examination and over five years control of the patients.

[Osteosarcoma: 2d malignant tumor following treatment with radiotherapy].
The authors report a case of postirradiation osteosarcoma that appeared in a seven year old girl after having received radiation therapy for a soft tissue sarcoma. The latent period between the two malignancies was 5 and a half years and the apparently radiation-induced osteosarcoma developed within the radiation field of the primary tumor.

Cancer occurring after radiotherapy and chemotherapy.
Radiotherapy and chemotherapy can effectively control cancer but can also cause new cancers to develop as long-term complications. Almost all types of cancer have been associated with radiotherapy. The breast, thyroid, and bone marrow are the organs most susceptible to radiation carcinogenesis. The bone marrow is also most frequently involved by chemotherapy and the leukemia risk is much higher than after radiotherapy. The combination of intensive radiotherapy and chemotherapy is particularly leukemogenic. The latent period between radiotherapy/chemotherapy and the appearance of a second primary cancer ranges from a few years to several decades. The risk for a second primary cancer following radiotherapy or chemotherapy emphasizes the need for life long follow-up of patients receiving such treatments. This is particularly the case in individuals with long life expectancy, for example, patients treated for childhood neoplasms. The benefits of radiotherapy and chemotherapy in oncology exceed the risks for second primary cancers. Efforts should be directed towards identifying those patients who will benefit from the treatments so that only they are exposed to the risk.

Features of second primary cancer in patients with gastric cancer.
BACKGROUND: In order to improve the prognosis of gastric cancer patients, the timely identification of second primary cancers is considered to be a crucial clinical problem. METHODS: We analyzed the clinicopathological data of 2250 patients with gastric cancer with regard to both synchronous and metachronous second primary cancers. RESULTS: Of 2250 patients, 95 (4.2%) had a second primary cancer. Both colorectal and lung cancer were frequently detected, followed by cancer in the liver, esophagus and breast. Regarding the time of detection for such second cancers, 65% of colorectal cancers were detected synchronously, while more than 80% of lung cancers were detected metachronously. The prognosis of gastric cancer patients with a second primary cancer was more negatively influenced by a second primary cancer than by a primary gastric cancer. CONCLUSION: Since gastric cancer patients may develop synchronous and metachronous second cancers in other organs, effective preoperative and postoperative diagnostic modalities both for second primary cancers, as well as for the recurrence of gastric cancer, need to be developed.

Survival following resection for lung cancer as a second primary cancer.
A second operation was done on 59 patients with lung cancer (7.4% of all those with lung cancer) as a second primary (double primary), during 1974-1991. There were 16 synchronous tumors (interval less than one year) and 43 metachronous tumors (interval over one year). The criteria for diagnosing lung cancer as a second primary from intrapulmonary metastases were any of the following: 1) different histologic type; 2) origin from carcinoma in situ; 3) gross appearance suggestive of primary lung cancer. The initial operation was in the stomach in 14 patients and in the lung in 10. The overall 5-year survival rate in the double primaries was 57.8%, and the prognosis was similar to those in the single primaries of the lung. Nineteen patients died from the second tumor following the second operation, compared with 5 from the initial tumor. The incidence of primary lung cancer increases, and close follow-up after resection for malignant neoplasms detects a new shadow in the chest roentgenogram. It offers a chance of early detection of primary lung cancer and subsequent resection with acceptable results.

[Early gastric cancer as a metachronic or synchronic tumor. Report of 6 cases].
Through a period of 16 years, 108 cases of early gastric cancer (EGC) were diagnosed at Hospital Mexico, a leading teaching hospital of Costa Rica's social security system and the University of Costa Rica. It was found that in four cases, the gastric neoplasia was a second primary tumor, and in the two remaining cases, the EGC developed synchronously to another neoplasm. Two of the four metachronic EGC were preceded by a uterine cervix neoplasm on stage lla; the third one was preceded by a breast adenocarcinoma, and the fourth one by a larynx cancer in a heavy male smoker. The treatment received for the first cancer was radiation therapy only, except for the breast cancer patient in whom surgery was employed as well. One of the patients with uterine cervix cancer developed an epidermoid bronchogenic cancer 17 years after the first tumor and 8 years after her EGC. In the two male patients with synchro tumors, the EGC developed together with a squasmous cell carcinoma of esophagus, and in the remaining one the EGC appeared simultaneously with a peritoneal mesothelioma. It is important to emphasize the presence of radiation therapy in the metachronous tumors, as well as the antecedent of smoking in the patient with three primary cancers, the esophagus one, and the larynx cancer patient.

An uncommon case of simultaneous malignant tumors: bronchioloalveolar cancer and Ewing's sarcoma in a 17-year-old girl: report of a case.
This report describes a 17-year-old girl with a simultaneous occurrence of bronchioloalveolar cancer and Ewing's sarcoma of the femur, which is a previously unreported association. This case emphasizes the existence of multiple primary malignant neoplasms even in adolescents. Primary lung cancer should therefore be considered in patients under 19 years of age who present with abnormal pulmonary lesions.

A clinical study of colorectal cancer accompanied by cancer of other organs.
BACKGROUND: The incidence of double primary neoplasms has increased in recent decades. The etiologies and epidemiologies of double primary neoplasms are under investigation, and relationships between some cancers are well established. A group of patients with double primary cancers was studied to determine the relationships between certain cancers. METHODS: From November 1982 to September 1993, 48 patients with colorectal cancer accompanied by cancer of another organ (double primary cancers) were treated here. The male-to-female ratio was 31 to 17. According to Warren's definitions, the patients were classified into two groups: synchronous and metachronous. Data collection was done on the basis of locations, pathological staging and interval between cancers. RESULTS: Among the 48 patients, extracolonic cancers were mainly found in the cervix (8), stomach (7), prostate (5), lung (5), urinary bladder (4), and breast (4). In the female patients, 88.2% (15/17) of extracolonic cancers were in the female reproductive organs. In male patients, 45% (14/31) of extracolonic cancers were GI tract neoplasms, and 35.5% (11/31) were cancers of the GU tract. Nearly half of the patients expired within two years after diagnosis of the second primary cancer. CONCLUSIONS: Cancers of the cervix, stomach, prostate, lung, urinary bladder and breast may have some etiologic factors in common with that of colorectuim. Thus, attention should be paid to these sites during the period of post-operative follow-up of the first primary cancer.

Clinicopathological features of gastric carcinoma patients with other primary carcinomas.
BACKGROUND: Multiple primary carcinomas are increasingly being found because of the development of diagnostic techniques and the increasing incidence of early stage carcinoma. The purpose of this study was to determine the prevalence and clinicopathological features of gastric carcinoma patients with other primary carcinomas. METHODS: There were 65 (incidence 2.6%) gastric carcinoma patients with other primary carcinomas compared with 2,444 patients with gastric carcinoma alone. RESULTS: Associated primary carcinomas were often found in the gastrointestinal (GI) tract, especially in the colon (33.8%). In patients with gastric carcinoma only, poorly differentiated adenocarcinoma was the most common (43.2%), followed by moderately and well-differentiated adenocarcinoma. Similarly, poorly differentiated adenocarcinoma (33.8%) was also the prevalent histological type in gastric carcinoma patients with other primary carcinomas, although its incidence was lower. The stage of gastric carcinoma did not differ between the two groups. The estimated 5-year survival rate was 51.6% for patients with gastric carcinoma alone, and 50.7% for those with other primary carcinomas; the difference was not significant (P=0.82). CONCLUSION: Gastric carcinoma should be treated aggressively, since the prognosis of gastric carcinoma patients treated for other primary carcinomas is not poorer than that of patients treated for gastric carcinoma alone.

[Distant metastasis of squamous epithelial carcinomas of the upper aerodigestive tract. The effect of clinical tumor parameters and course of illness].
Screening for distant metastases from head and neck tumors is still controversial. In the present study, the records of 1087 patients with newly diagnosed squamous cell carcinomas of the upper aerodigestive tract were reviewed retrospectively to determine clinical factors influencing the incidence and location of distant metastases. Overall, 130 patients (12.0%) developed clinical evidence of metastatic disease, 17 of whom (1.6%) had metastases at the time of initial presentation. The rate of distant metastases significantly increased with the initial stage of tumors (P < 0.00001) and the occurrence of local and/or regional recurrences (P < 0.00001) or of second primaries below the clavicles (P < 0.0005). The locations of primary cancers as well as histopathologic grading were not independent risk factors for the development of distant metastases. They mainly reflected different frequency distributions of stages. The lungs, liver and bones were the most common sites of metastatic disease, being involved in 68.5%, 23.8% and 20.0% of cases, respectively. Our findings show that at the time of initial presentation chest X-ray alone appears to be sufficient to exclude distant metastases from tumors classified as T1-3 NO. Further screening comprising abdominal ultrasound, bone scanning and/or CT scans of the thorax is particularly indicated for patients with advanced-stage disease, local and/or regional recurrences and second primaries below the clavicles. However, the individual decisions should consider whether the detection of distant metastases will significantly affect clinical management.

Tumor angiogenesis in primary and metastatic colorectal cancers.
PURPOSE: Angiogenesis is needed to sustain growth of both primary and metastatic lesions; however, comparisons in microvessel density between a primary tumor and its metastases have not been widely performed. We studied microvessel density in primary colorectal cancers and their liver metastases. METHODS: Sections from 32 primary lesions and 53 hepatic metastases were immunostained with a monoclonal antibody for von Willebrand's factor, an endothelial cell marker. Blood vessels were quantified under x 100 magnification using both conventional light microscopy and computer-assisted image analysis. Primary and metastatic angiogenesis scores (AS), i.e., vessel counts, were analyzed with respect to tumor size, hepatic multicentricity, synchronicity, resectability, and patient survival. Using computer-assisted calculations, the same analyses were performed using blood vessel to tumor surface area ratios, vessel wall thickness, and intensity of immunostaining. RESULTS: Angiogenesis scores were significantly lower in metastatic lesions compared with their primary tumors (P < 0.0001). Primary AS did not correlate with metastatic tumor size, resectability, multicentricity, or patient survival. Metastatic AS strongly predicted patient survival (P < 0.0009) but with a negative coefficient, i.e., higher scores were associated with improved survival. Metastatic AS were higher in resectable than in nonresectable metastases and in solitary than in multiple metastases; however, these trends were not statistically significant. Metachronous liver lesions had significantly higher angiogenesis scores than synchronous metastases (P < 0.04). Similar trends were seen using computer-assisted image analysis. CONCLUSIONS: These results indicate that in presence of an established metastasis, there is a weak angiogenic relationship between a primary tumor and its metastasis. Heterogeneity in metastatic lesions cannot be explained solely by studying angiogenesis in primary tumors. Microvessel density in a primary tumor may not be useful as an independent prognostic indicator in late stages of disease. In such cases, assessment of microvessel density in a metastatic tumor whenever possible may be an indicator of prognosis.

Multiple primary melanomas: an analysis of cancer registry data from Victoria and New South Wales.
All primary invasive cutaneous malignant melanomas (CMM) diagnosed in Victoria and New South Wales from 1985 to 1989 were obtained from the population-based cancer registries. Altogether 14,590 people with first CMMs were followed for at least 2 years, during which time 496 multiple primary CMMs were identified. Of the study population, 3.4% developed a second primary CMM and 0.3% developed three or more. It was estimated that 4.5% of people would develop a second CMM within 5 years of the first and that the risk was higher in males, particularly in men aged over 70 years. With regard to metachronous primaries, only age and thickness of the first primary were significant predictors of the thickness of the second: older people tended to have thicker CMMs and second CMMs were generally thinner than the first. Body site concordance was higher than expected by chance, particularly for synchronous diagnoses. The high degree of site concordance of metachronous primaries lent support to the hypothesis that skin adjacent to the first CMM might have undergone a 'field effect', rendering it at increased susceptibility to malignancy.

Mutations of the P53 tumor suppressor gene as clonal marker for multiple primary lung cancers.
OBJECTIVES: Second primary lung cancers are prevalent after treatment for initial lung cancer, and the lung is also one of the most frequent sites for recurrence after removal of early-stage lung cancer. The objective of the present study is to clarify the clonal origin of the second tumor with the p53 gene mutation used as a clonal marker. METHODS: Of 794 consecutive patients who underwent pulmonary resection for primary lung cancer from 1980 to 1993, 22 required second pulmonary resection during the follow-up period, with a median interval of 38 months. We examined 16 of these patients for mutations of the p53 gene occurring in exons 5 through 8 by the polymerase chain reaction/single strand conformation polymorphism method. Differential diagnosis was also made on a morphologic basis, considering the degree of cellular differentiation and cytologic subtypes. RESULTS: Nine of the 16 patients analyzed had at least one p53 mutation in their tumors. We were thus able to make molecular diagnoses for these patients. The mutational status of the p53 gene was discordant in all nine patients, suggesting a different clonal origin despite the fact that six of them had almost identical histologic features. CONCLUSIONS: Analysis of p53 gene mutations was thus useful in distinguishing second primary lung cancers from recurrent tumors. The observed heterogeneity of p53 status was also in line with the "field cancerization" concept.

Comparative genomic hybridisation as a supportive tool in diagnostic pathology.
AIMS: Patients with multiple tumour localisations pose a particular problem to the pathologist when the traditional combination of clinical data, morphology, and immunohistochemistry does not provide conclusive evidence to differentiate between metastasis or second primary, or does not identify the primary location in cases of metastases and two primary tumours. Because this is crucial to decide on further treatment, molecular techniques are increasingly being used as ancillary tools. METHODS: The value of comparative genomic hybridisation (CGH) to differentiate between metastasis and second primary, or to identify the primary location in cases of metastases and two primary tumours was studied in seven patients. CGH is a cytogenetic technique that allows the analysis of genome wide amplifications, gains, and losses (deletions) in a tumour within a single experiment. The patterns of these chromosomal aberrations at the different tumour localisations were compared. RESULTS: In all seven cases, CGH patterns of gains and losses supported the differentiation between metastasis and second primary, or the identification of the primary location in cases of metastases and two primary tumours. CONCLUSION: The results illustrate the diagnostic value of CGH in patients with multiple tumours.
