Management problems in patients with recurrent squamous cell carcinoma (SCC) of the external ear (pinna) have prompted a review of the management and treatment outcomes of patients who present with localized disease. Forty patients were seen over a 15-year period (1972 to 1991). Thirty-six were men, and 4 were women, with an age range from 43 to 93 years (average age: 71 years). Presenting TNM status was stage 0 in 2 patients, stage I in 15 patients, stage II in 13 patients, stage III in 2 patients, stage IV in 4 patients, and unknown stage in 4 patients. Thirty-six patients had clinically negative nodes at presentation (N0), and 4 had palpable nodes (N+). The primary treatment was local excision in 13 patients, Mohs' micrographic surgery in 16 patients, local excision plus external beam radiotherapy in 4 patients, and radical resection (parotidectomy/neck dissection/mastoidectomy) with or without radiotherapy in 5 patients. Two patients with stage IV disease died after diagnosis and prior to treatment, and two other patients with stage IV disease received palliative chemotherapy. Twenty patients developed recurrence from 2 months to 8 years. It included nine local recurrences, eight regional recurrences (parotid/neck/mastoid), and three distant metastases (lung or brain). After treatment of the recurrences in 20 patients, 8 are alive 15 months to 16 years later, 2 patients died of other diseases, and 10 patients died of SCC. The recurrences were managed by reoperation, radiotherapy, or chemotherapy. From the results of this study, we conclude that localized carcinoma of the external ear has a high propensity for local and regional failure and merits more aggressive treatment of the primary lesion and elective treatment of the regional lymph nodes and parotid gland in high-risk patients.

Expression of T-cell receptor (TCR) gene rearrangements in tumor-infiltrating lymphocytes (TILs) within primary and metastatic melanoma specimens was studied. In order to analyze TCR gene transcription in TILs within these tissues, we analyzed reverse transcribed complementary DNA from mRNA directly from tissues using the polymerase chain reaction. The polymerase chain reaction-amplified products were confirmed by dot or Southern blot hybridization with C alpha or C beta oligoprobes. First, we investigated the diversity of TCR V alpha and V beta gene usage in human malignant melanoma patients with multiple metastasis. We found in one patient, bearing multiple skin lesions, that the patterns of TCR V alpha and V beta repertoires in different sites of the skin (leg and chest wall) were almost the same. However, in another patient with skin and brain melanomas, different TCR repertoires were presented. Next, we examined the usage of murine TCR V beta genes in TILs within the primary and metastatic sites (liver, lung, and brain) of C57BL/6 mice bearing B16-F10 murine melanoma. The population of TILs in each primary and metastatic site expressed from one to four TCR V beta genes. In each metastatic site, the profile of TCR V beta gene expression was different. A different TCR V beta usage in TILs distributed within metastases of various organs may reflect differences in tumor antigenicity at these sites or may be due to differential homing patterns to these tumors.

An assessment system for the prognosis of metastatic spine tumors was evaluated for 64 cases who had undergone surgery. Six parameters were employed in the assessment system: 1) the general condition, 2) the number of extraspinal bone metastases, 3) the number of metastases in the vertebral body, 4) metastases to the major internal organs (lungs, liver, kidneys, and brain), 5) the primary site of the cancer, and 6) the severity of spinal cord palsy. Each parameter ranged from 0 to 2 points. The total score obtained for each patient can be correlated with the prognosis, while being valuable in predicting it. However, the prognosis could not be predicted from a single parameter. In conclusion, an excisional operation should be performed on those cases who scored above 9 points, while a palliative operation is indicated for those who scored under 5 points.

The aim of the current pilot study was to determine whether placental isoferritin (PLF) can be detected in the serum of patients with metastatic breast cancer. Sera were obtained from breast cancer patients with metastatic disease (n = 100), from breast cancer with no evidence of disease (n = 70) and from healthy female controls (n = 34). PLF and total serum ferritin levels were independently measured using specific monoclonal antibody ELISAs in a double-blind study. It was found that the mean serum PLF levels were significantly elevated only in patients with visceral metastases (lung, liver, brain) compared with the levels of patients with non-visceral metastases (bone, skin) or with healthy controls. Contrary to this, analysis of total serum ferritin levels did not reveal significant differences between these groups. Considering 0-10 units/ml as a PLF negative result, it was found that PLF was negative in 87.5% of healthy controls and in 96% of breast cancer patients with no evidence of disease. In contrast, PLF was positive in 73% of the patients with visceral metastases and in 29.7% of those with non-visceral metastases. The striking difference between visceral and non-visceral metastases is not yet understood. It could result from a difference in the degree of vascularisation or, alternatively, a difference in the cell types and genes expressed by cells metastasizing to visceral or non-visceral organs.

Acute intra-abdominal conditions due to metastatic primary lung cancer have been reported rarely in the literature, with a very high associated operative mortality noted. We report on 13 patients with metastatic lung cancer who underwent exploratory celiotomy from 1976 through 1988. Twelve were men, and their ages ranged from 43 to 68 years. All but 1 of the patients had known extra-abdominal metastases (primarily brain) at the time of the abdominal symptoms. In 11 patients the small bowel was the site of metastases. One patient had cecal involvement, while the 13th had common bile duct obstruction. The most common histologic type was a large-cell carcinoma. The extent of surgery was dependent on the pathologic findings encountered; most patients underwent resection of obstructed or perforated intestine. Eight of the 13 patients survived and were discharged from the hospital after a mean stay of 17 days. We conclude that acute intra-abdominal conditions from metastatic lung cancer can often be treated successfully by prompt surgical exploration, including bowel resection or bypass if necessary.

To assess the value of whole brain radiotherapy (WBRT) after complete resection of a single brain metastasis we reviewed the records of 98 patients who had elective craniotomy between 1978 and 1985. Seventy-nine patients received postoperative WBRT (Group A) and 19 patients no radiotherapy (RT) (Group B). Neurological relapse was designated as local (i.e., at the site of the original metastasis) or distant (i.e., elsewhere in the brain). Postoperative WBRT significantly prolonged the time to any neurological relapse (P = 0.034) with a 1-year recurrence rate of 22% in Group A and 46% in Group B patients; however, it did not specifically control either local or distant cerebral recurrence. Recurrence of metastatic brain disease was not affected by location of the original lesion; however, meningeal relapse occurred in 38% of cerebellar lesions, but only in 4.7% of supratentorial metastases (P = 0.003). The total radiation dose or fractionation scheme of RT did not affect survival nor time to neurological relapse. The median survival was 20.6 and 14.4 months for Groups A and B, respectively (not statistically different). Forty-eight percent of Group A and 47% of Group B patients survived for 1 year or longer; however, 11% of patients who had received RT and survived 1 year developed severe radiation-induced dementia. All patients with radiation-related cerebral damage received hypo-fractionated RT with high daily fractions as commonly designed for rapid palliation of macroscopic brain metastases.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of pancreatic carcinoma associated with marked eosinophilia is reported. A 71-yr-old man was admitted to hospital because of melena and abdominal pain. The systematic examinations revealed pancreatic adenocarcinoma with multiple metastases (rectum, lung and brain). The leukocyte count was gradually increased and reached up to 81.7 X 10(9)/l, of which 54% consisted of eosinophils. Colony-stimulating factor (CSF) was detected both in the patient's serum and in the tumor extracts by a normal human bone marrow culture system. The colonies which were stimulated with patient's serum largely consisted of granulocyte, granulocyte/macrophage and eosinophil types. These results suggest that blood leukocytosis and eosinophilia were due to a high concentration of plasma CSF, which was probably produced by the tumor cells.

Organ scans are generally performed on patients with bronchogenic carcinoma only when clinical evaluation is suspicious for metastases. However, it is not clear whether the clinical abnormalities will direct attention to the single organ which should be scanned, or if all three organs (bone, brain, liver) should be evaluated if any clinical abnormality is present. We investigated the use of triple organ radionuclide scanning and computerized tomography (CT) of the brain in the initial staging of patients with non-small cell bronchogenic carcinoma with no obvious metastases. Of 122 patients with newly diagnosed lung cancer, 53 met our criteria for further study. Thirty-three (62 percent) of these had at least one clinical abnormality suggestive of metastasis. Bone scanning detected metastases in seven (21 percent) and head CT in two additional patients (6 percent). Brain and liver scanning had no yield. In only five of these nine patients did the clinical abnormality direct attention to the organ with detectable metastases. Twenty of the 53 (38 percent) patients had a negative routine clinical evaluation, yet bone scanning showed metastases in three (15 percent). We concluded that clinical abnormalities are not specific for the organ in which metastases may be detected, so three scans (bone, liver, CT of the brain) should be obtained if there is any suspicion of metastasis based on history, physical examination, and laboratory tests. The value of bone scanning in clinically normal patients deserves further study.

Although much research has been done to isolate factors that have good prognostic value for cure in breast cancer, comparatively little attention has been paid to the large variation in the metastasis-free interval (MFI) in those who are not cured. In this paper we studied 247 patients who were given curative treatment for breast cancer, all of whom developed metastatic disease. The MFI varied from 2 months to 22 years and was found to depend on nodal status, initial T-stage, and possibly, location of the tumor within the breast; it did not depend on age of the patient or histologic appearance of the tumor. In addition, the time from first relapse to death did not correlate with the MFI. With one exception (brain) the initial site of distant metastasis was the same in late relapsers as in early relapsers.
