We evaluated adoptive immunotherapy using LAK cells combined with systemic administration of interleukin-2 (IL-2) in 11 patients with metastatic renal cell carcinoma. The LAK cells were generated by incubation in serum-free medium (AIM-V) supplemented with IL-2 (1,000 U/ml) for 4 days and were generally administered twice weekly (4 times/cycle). Daily administration of IL-2 (50 x 10(5) U) was started 3 days prior to the first LAK infusion and continued throughout the cycle. Each course of therapy comprised 1-6 cycles, with the total dose of LAK cells and IL-2 varying from 3.3-52.6 x 10(9) cells and 140-900 x 10(5) U, respectively. Clinical response was evaluated in terms of metastasis to specific organs (lung only: eight cases, lung and brain: one, lung and lymph nodes: one, lung and bone and pleuropericardium: one). The outcome was complete response in one patient, partial response in one, no change in six and disease progression in three. The response rate was 18.8%. This therapy was most effective against pulmonary
metastases
. Adverse reactions to LAK cell infusion included fever, headache, and chills.
Eosinophilia
and weight gain due to IL-2 administration were also observed. However, all of these symptoms were transient and no serious side effects occurred. In these patients, the proportion of natural killer (NK) cells (CD16) and cells with IL-2 receptor (CD25) among PBL was increased markedly in the early phase of therapy, and activated T cell (CD3+DR+) and suppressor T cells (CD8+11+) increased significantly at a later phase. It was suggested that the clinical response would be expected in case of increasing of CD16 cells or CD25 cells and augmentation of NK or LAK activity. Our results indicate that this regimen of adoptive immunotherapy shows some promise for the treatment of advanced renal cell carcinoma.

A case report is given of a very rare spontaneous mast cell tumor in the eyelid of the left eye of a female Wistar rat used in a long-term oral toxicity study.
Metastasis
of the tumor had occurred in the mandibular lymph nodes and in the liver. Clinically, the animal showed blepharospasm, dacryorrhoea, and exophthalmus. Hematologic findings included slight
eosinophilia
and a remarkable basophilia. At necropsy, a bilateral conjunctivitis was diagnosed and a tumorous mass was found in the left submandibular region. Histologically, the tumor was composed of round to polygonal cells with pale cytoplasm, containing abundant predominantly basophilic granules. The intracytoplasmatic granules stained metachromatically with Toluidine blue and immunostained positively with serotonin. Numerous eosinophils were scattered throughout the tumor and were also present in other organs. Cells with round, oval, or indented nuclei and abundant cytoplasm, containing pronounced eosinophilic granules, were found in spleen and bone marrow. They turned out to be immature stages of eosinophilic granulocytes. Characteristics of the present tumor are compared with observations on mast cell tumors in other species.

Sclerosing mucoepidermoid carcinoma with
eosinophilia
(SMECE) is a recently recognized malignant neoplasm of the thyroid gland. Two additional cases of this condition which occurred in a 70-year-old woman and a 69-year-old woman are presented. The case of the 70-year-old woman (patient 1) is the first report of distant metastasis, besides lymph node metastasis, for this type of tumor. The patient initially presented with a thyroid mass, and the thyroid gland with surrounding cervical lymph nodes was removed. Because of focal keratin "pearl" formation, the tumor was misinterpreted as a metastatic squamous cell carcinoma to the thyroid. Approximately 4 years later, the patient developed a left supraclavicular mass and lung densities. A pathological fracture of the right humeral head followed, and the left supraclavicular mass recurred along with newly developed subcutaneous nodules on the chest wall and arm. Open lung and bone biopsies revealed metastatic SMECE, which was morphologically identical to that of the thyroid mass. The 69-year-old woman (patient 2) had, in 1983, undergone thyroidectomy with left radical neck dissection; this had been diagnosed as follicular carcinoma of the thyroid with lymph node involvement. After multiple isolated lymph nodes
metastases
, the patient developed locally extensive, recurrent tumor that showed microscopic features of SMECE. Review of the previous thyroid tumor and lymph nodes revealed the same type of histology. To our knowledge, only a single report containing eight cases of this distinctive carcinoma of the thyroid has been published. Herein we describe characteristic morphological features of two additional cases of this rare malignancy, one with distant metastasis, and we review the related literature.

A prospective phase II trial was carried out to define the activity of a low-dose subcutaneous regimen of interleukin-2 (IL-2) and interferon alpha-2b (IFN-alpha) in combination with intravenous administration of vinblastine (VLB) in patients with metastatic renal cell cancer (RCC). Thirty-one patients with advanced RCC who had received no prior biochemotherapy were treated with IL-2 4.5 MU x 2/24 h thrice weekly for 2 weeks, IFN-alpha 3 MU/24 h thrice weekly (alternating days) for 2 consecutive weeks and VLB 4 mg/m2 every 3 weeks. Patients were to have a 1-week rest period after each 2 weeks of therapy with cytokines. Treatment was repeated every 3 weeks. Maximum duration of treatment was 1 year. Treatment was administered on an outpatient basis. There were 4 complete (12.9%) and 8 partial responses (25.8%), with an overall response rate of 38.7%. The median duration of response was 6.5 months. Responses were seen in lung, lymph nodes, bones, liver and other tumor
metastases
. Toxicity was mild to moderate, consisting of fever, anorexia, malaise and nausea-vomiting in > 80% of patients. Hypotension and transient alopecia occurred in > 20% of patients. Liver enzyme elevation was frequently observed. Treatment-induced
eosinophilia
occurred in the majority of patients, while in 52% of patients granulocytopenia grade II and grade III did not require dose modification of drugs. Transient inflammation and local induration at the injection sites was observed in the majority of patients. None of the patients experienced major VLB-related toxicity and no toxic deaths occurred. This three-drug combination immunochemotherapy may be a promising regimen with modest toxicity in advanced RCC.

Sclerosing mucoepidermoid carcinoma with
eosinophilia
(SMECE) is a recently described carcinoma of the thyroid gland associated with Hashimoto's thyroiditis and considered to have a relatively indolent clinical course. We describe two patients with SMECE and its aspiration and exfoliative cytologic features. Patient 1 was a 39-year-old woman with a goiter for many years. Examination of the lobectomy specimen revealed SMECE associated with Hashimoto's disease; 4 months later a total thyroidectomy was performed,
metastases
were found in nine lymph nodes in the neck. Two years later, fine-needle aspiration biopsy (FNAB) of a paritracheal mass revealed recurrent tumor. After 2 more years, two pleural fluid samples contained metastatic carcinoma with eosinophils. Patient 2 was a 61-year-old man with thyromegaly and vocal cord paralysis. The FNAB revealed a poorly differentiated carcinoma. The subsequent thyroidectomy demonstrated SMECE. Two years later, an FNAB of a vertebral mass demonstrated metastatic mucoepidermoid carcinoma. In all specimens, malignant cells with definite glandular and squamoid differentiation were present in small cohesive aggregates; eosinophils associated with the tumor cells were present in all specimens.

The vast majority of cases of
eosinophilia
in North America are caused by allergic processes. In individual cases, a short differential diagnosis of the most likely causes can be formulated on the basis of the absolute eosinophil count. The extensive laboratory workup previously recommended by some authorities is probably not justified unless detailed history taking and physical examination indicate a need for specific investigations. Although the possibility of missing an occult neoplasm has been used to justify extensive investigation, this is usually not necessary because most tumor-associated
eosinophilia
is accompanied by widely
metastatic disease
. History taking should emphasize the possibility of drug-induced or helminth-associated
eosinophilia
. If the history indicates travel, dietary, or other exposure risks, stool examination for ova and parasites is worthwhile. If a possible allergic cause is suspected, testing for evidence of atopy may be performed concomitantly with testing for parasitic infection. A follow-up white blood cell count with differential is recommended to ascertain whether
eosinophilia
has resolved. When an absolute eosinophil count of more than 1.5 x 10(9)/L persists for longer than 6 months, idiopathic hypereosinophilic syndrome must be ruled out.

Seven immunocompetent, revaccinated patients with surgically incurable cutaneous melanoma underwent treatment of dermal and/or subcutaneous
metastases
with twice-weekly intratumoral injections of escalating doses (10(4)-2 x 10(7) plaque-forming units (PFU)/lesion; 10(4)-8 x 10(7) PFU/session) of a vaccinia/GM-CSF recombinant virus for 6 weeks. Patients with stable or responding disease were maintained on treatment until tumor resolution or progression. Systemic toxicity was infrequent, dose-related, and limited to mild flu-like symptoms that resolved within 24 hours. Local inflammation, at times with pustule formation, was consistently seen with doses of > or =10(7) PFU/lesion. Chronically treated lesions showed a dense infiltration, with CD4+ and CD8+ lymphocytes, histiocytes, and eosinophils. All seven patients developed an antivaccinia humoral immune response 14-21 days following revaccination. Despite the presence of these antivaccinia antibodies, the reporter gene was expressed, as judged by the development of anti-beta-galactosidase antibodies in all patients. Passenger cytokine gene function was evidenced by the presence of virally encoded GM-CSF mRNA at injection sites both early (weeks 1 and 5) and late (week 31) in the course of treatment.
Eosinophilia
at treatment sites indicated that physiologically significant levels of functional cytokine were generated. However, there were no changes in the total number of peripheral white blood cells or in the numbers or percentages of polymorphonuclear leukocytes, monocytes, or eosinophils. GM-CSF was not detected in the sera. The two patients with the largest tumor burdens failed to respond even at treatment sites. Three patients had mixed responses, with regression of treated and untreated dermal
metastases
and progression of disease elsewhere. One patient had a partial response, with regression of injected and uninjected regional dermal
metastases
. Residual melanoma was excised, rendering the patient disease free. One patient with only dermal
metastases
confined to the scalp achieved a complete remission. Sequential administration of escalating doses of a GM-CSF recombinant vaccinia virus is safe, effective at maintaining passenger gene function, and can induce tumor regression.

The mode of tumor invasion has been suggested to have a relationship to the occurrence of cervical metastasis and to prognosis in oral squamous cell carcinoma (OSCC). However, a tumor usually does not have a single mode of invasion, and the importance, if any, of the relative proportions of different modes for metastatic potential has not been studied. Forty two cases of OSCC resected with cervical lymph nodes were selected, 20 of which had nodal
metastases
and 22 which had not. The mode of invasion in the tumor-host interface was classified as: I - pushing borders, II - bands, III - thin cords, IV - single cells and analyzed in 20 consecutive medium power fields. Also studied were other morphological parameters: perineural and angiolymphatic invasion, tissue
eosinophilia
, mitosis and intensity of inflammatory infiltrate at the tumor-host interface. The majority of the cases (95.2%) showed two or more modes of invasion. Modes I, II and III occurred with similar frequency in cases with and without
metastases
. Mode II was the commonest and most extensive in both groups. No mode of invasion was significantly associated with
metastases
, independent of its extension. The other morphological parameters were neither significantly associated with cervical metastasis. In conclusion, OSCC usually shows two or more modes of tumor invasion if a large extension of tumor-host interface is analyzed. However, the relative proportions of the modes have no correlation with the metastatic potential.

Mucoepidermoid carcinoma is a rare primary thyroid tumor with indolent biologic potential. Two types of tumors have been described under this category: mucoepidermoid carcinoma (MEC) and sclerosing mucoepidermoid carcinoma with
eosinophilia
(SMECE). The MEC shows both squamous and glandular differentiation in a background of a noninflamed gland, whereas SMECE is characterized by extensive sclerosis, squamous and glandular differentiation, a concomitant inflammatory infiltrate rich in eosinophils, and a background of lymphocytic thyroiditis. We present nine cases of these entities: five MEC and four SMECE. All tumors occurred in women (age 27 to 73 years). Five tumors showed extrathyroidal invasion and multiple lymph node
metastases
. One case of MEC showed a concomitant tall cell variant of papillary carcinoma with vascular invasion, and two cases showed intimately associated areas of usual papillary carcinoma. One of the latter cases also showed areas of transformation to anaplastic carcinoma. In all cases of SMECE and in only one case of MEC, the uninvolved thyroid tissue showed lymphocytic thyroiditis. Follow-up information was available in four of the nine cases (3 months to 7 years). Two patients with SMECE are alive with no evidence of disease. One patient with MEC and tall cell variant of papillary carcinoma died of disease after 3 months, and the patient with anaplastic carcinoma died after 5 months with lung metastasis. Both MEC and SMECE were positive for cytokeratin and negative for calcitonin. All cases of MEC were positive for thyroglobulin, whereas all cases of SMECE were negative. The immunohistochemical findings suggest that both MEC and SMECE have different histogenesis.

Peripheral blood
eosinophilia
is a well-recognised but unusual manifestation of malignancy, and may represent a paraneoplastic phenomenon. We present a case of poorly differentiated adenocarcinoma of the stomach associated with severe peripheral blood
eosinophilia
A 55-year old man was admitted for abdominal pain of one week duration. An incidental finding of leucocytosis with
eosinophilia
was noted. After excluding haematological and infectious causes, an oesophagogastroduodenoscopy (OGD) followed by biopsy confirmed the diagnosis.
Eosinophilia
appears to be a response to cytokine production,and treatment is aimed at the underlying malignancy, and reducing the eosinophil count when necessary, to prevent end-organ damage. Studies have shown that peripheral
eosinophilia
is associated with disseminated,
metastatic disease
and hence signifies a poor prognosis,whereas tissue
eosinophilia
in advanced cancer has a better survival rate.
