Meibomian sebaceous gland adenocarcinoma of the eyelid is a rare lethal neoplasm. It accounts for less than 1% of all eyelid tumors. There are approximately 200 cases described in the literature. The incidence of regional metastases is 17-28%. Once metastases are present, only half of the patients survive five years. Presented are two cases with neck node metastases. In one of the patients the primary lesion was initially treated with radiation therapy with an unsuccessful result. Subsequently full thickness, wide excision of the lower lid was required to control the primary. Eyelid oculoplastic reconstruction was performed using a masolabial rotation skin flap lined with nasal septal composite graft (cartilage and mucosa). Orbital exenteration was necessary to control the primary tumor in the other patients. The regional metastases in both patients were treated with parotidectomy with preservation of the facial nerve, radical neck dissection and postoperative radiation therapy. One of the patients with poorly differentiated adenocarcinoma died due to brain metastasis. I feel that combined treatment of radical surgery to the primary site, parotidectomy, radical neck dissection and planned postoperative radiation therapy may improve the five-year survival of patients with regional node metastases.

We have treated surgically 11 patients with thyroid carcinoma that had infiltrated into the trachea. Three patients had primary tumours, and eight had recurrent tumours after previous operations. Sleeve resection of trachea was performed where thyroid carcinoma had proliferated; the trachea was reconstructed by end-to-end anastomosis. In two patients 10 rings of the trachea were resected. In three patients the anterior half of the cricoid cartilage was resected along with the cervical trachea. In one patient tracheoplasty was performed using partial extracorporeal circulation because severe tracheal stenosis prevented endotracheal intubation. Two of the 11 patients died from the surgery and one from disseminated metastases. One patient who had undergone tracheal resection for thyroid carcinoma three years and five months previously had a recurrence of the tumour in the trachea adjacent to the anastomosis, and a second tracheal resection was performed. In three patients postoperative laryngeal stenosis occurred. Five patients are alive and well two years and one month to four years and seven months after their operations. The histological pattern of the tumour was papillary adenocarcinoma in all 11 patients.

Three distinct subpopulations of tumor cells derived from a single parent strain BALB/cfC3H mammary adenocarcinoma were tested in vivo for sensitivity to cyclophosphamide, methotrexate, and 5-fluorouracil. Treatment was begun either 2 days after s.c. tumor cell injection or at the time when the tumors became palpable. It was given on a weekly basis for 4 weeks. The mice were observed for growth of the primary implant and for development of spontaneous metastases. The three subpopulations differed markedly in their sensitivity to the drugs. The effects of the drugs ranged from induction of regression of the "primary" to enhancement of metastases. The effect on primary growth was independent of that on metastasis. The effect of the time of administration of the drugs also varied among the subpopulations. The sublines were also tested in vitro with methotrexate and 5-fluorouracil. Again there were marked differences in sensitivity to inhibition of cell division by the drugs. The relative sensitivities in vitro did not correlate with observations in vivo. The existence of subpopulations of tumor cells, differing in sensitivity to therapeutic agents, within a single neoplasm, presents a challenge to development of assays capable of predicting drug response and to the selection of combination therapies.

Circulating CEA levels were determined in 102 patients wtih histologically proven pancreatic carcinoma and 26 patients with chronic pancreatitis. In the group with pancreatic carcinoma eleven patients had resectable tumors, the mean CEA in the nonjaundiced patients was 10 +/- 5 ng/ml while the mean value in jaundiced patients in this group was 27 +/- 40. Thirty-four patients with nonmetastatic locally unresectable disease had a mean serum CEA of 25 +/- 52 with a range of 1 to 250 ng/ml. Twenty-one percent had values of 5 ng/ml or less. The mean value in 57 patients with metastatic disease was 97 +/- 194 with a range of 0.05 to 1000 ng/ml and 19 percent had values of 5 ng/ml or less. Survival of patients with locally unresectable or metastatic carcinoma was significantly longer in those patients who had a normal CEA at the time of diagnosis. Circulating CEA in the metastatic group was much lower in patients with nonhepatic metastases as well as in those with well differentiated adenocarcinoma histology. Twenty-three patients with chronic pancreatitis and normal serum bilirubin had a mean CEA value of 5.3 +/- 4 ng/ml with 65% of values being 5 ng/ml or less but the CEA ranged from 4.6 to 27 in three who were jaundiced.

A 57-year-old woman complaining of decreased vision for six months had a mass expanding the choroid inferonasally in the right eye. Clinical examination, ultrasonography, and fluorescein angiography were consistent with a malignant melanoma. The eye was enucleated and pathologic studies showed an adenocarcinoma of the retinal pigment epithelium (RPE). Malignant tumors of the RPE may simulate exactly choroidal melanomas clinically, but apparently have a much better prognosis, in that very few cases have been documented to produce metastatic disease. The vast majority of cases studied histopathologically, in which a diagnosis of adenocarcinoma of the RPE has been made, are low-grade malignant neoplasms with the absence of invasion beyond the choroid or lamina cribrosa at the time of enucleation.

Six female beagle dogs were given a daily dose of 100 mg MOCA, by capsule, 3 days per week for the first 6 weeks and then 5 days per week continuously for periods up to 9.0 years. The dose varied from 8 to 15 mg/kg body weight/day among the dogs. Six female beagle dogs were kept as untreated controls. The test was terminated after 9.0 years of treatment. The average plasma glutamic-pyruvic transaminase activity of the dogs fed MOCA was higher than that of the controls during the first and last two years on test. During the eighth and ninth years the urine sediment from MOCA dogs contained excessive numbers of erythrocytes, leukocytes, and epithelial cells. Some epithelial cells contained abnormalities that suggested neoplasia in the genitourinary tract. One MOCA dog, sacrificed after 8.3 years on test was found to have a papillary transitional cell carcinoma of the urinary bladder. Of four MOCA dogs sacrificed after 9.0 years on test, three were found to have papillary transitional cell carcinomas of the urinary bladder and one had a combined transitional cell carcinoma and adenocarcinoma of the urethra. The urethral tumor had metastasized to the liver, but the papillary transitional cell carcinomas found in the other four dogs did not invade the muscle layers of the bladder wall and did not metastasize. Since no urinary bladder tumors were found in the six control dogs, MOCA was considered to be carcinogenic for the urinary bladder of dogs under the conditions employed (p less than 0.025, Fisher's Exact Test, one tail). Three of five MOCA dogs contained hyperplastic nodules in the liver with no such nodules in six control dogs (p greater than 0.05, Fisher's Exact Test, one tail). This was considered to be suggestive of an effect of MOCA treatment.

The synthesis for cis-4,4' (1,2-cyclopropanediyl)bis(2,6-piperazinedione) (cis-3) is discussed. Stereoselective effects on metastases of cis-3 and the previously reported trans-2 isomer were compared to conformationally mobile ICRF-159 using a Syrian hamster lung adenocarcinoma (LG1002). Whereas ICRF-159 and cis-3 significantly inhibited lung metastases the trans-2 isomer significantly increased the number of metastatic nodules in the lung. Thus, these studies have revealed that, at least in one tumor model, antimetastatic activity can be separated from metastatic potentiating activity by controlling drug geometry.

An observation of malignant mesothelioma of the pericardium is described. The tumour grew as papillomatous formations and thick plaques lining the inner surface of the pericardium with transition to the epicardium and the development of massive hemorrhagic pericarditis. The mixed nodular-plate form is histological close to adenocarcinoma. There were metastases in the pleura, paratracheal and posterior mediastinal lymph nodes. Clinically the disease ran a course with angina pectoris and simulated idiopathic myocarditis not confirmed histologically.

Two clinical observations of primary carcinoma of the descending branch of the duodenum in men of 39 and 58 operated for this disease are described. Histologically the tumor was papillary adenocarcinoma. No metastases into regional lymph nodes or internal organs were found. In the patient of 39 the carcinoma of the duodenum was accompanied by papillomatous outgrowths in the opening of the pancreatic duct.

From 1956 to 1975 21 patients (13 females and 8 males) with thyroid cancer developed by age 14 have been observed at the Istituto Nazionale Tumori of Milan. Follicular adenocarcinoma was diagnosed in 4 cases and papillary adenocarcinoma in 17. Five patients (24%) had been given previous cervical irradiation for benign conditions. At admission lung metastases were evident in 2 patients (one affected by follicular and the other by papillary adenocarcinoma). All patients were submitted to surgical treatment, which in most cases consisted in total thyroidectomy plus elective lymph node dissection; serious postoperative complications were not observed. External irradiation was given to 4 patients, since surgery had not been radical. Radioiodine treatment was performed in the 2 patients with lung metastases: in the patient with follicular adenocarcinoma metastases disappeared after 131I treatment, whereas in the other one they still persist unmodified 10 years later. A local recurrence occurred in 3 cases and pulmonary metastases in one: all of them made an apparent recovery after surgical and/or radioiodine treatment. All patients are alive and, except one, without evidence of disease after a follow-up period from 14 months to 21 years. Although differences in evolution have been noted according to the histotype, the prognosis of thyroid cancer in childhood is good, even if distant metastases are present.
