During the years 1960 to 1989, 145 patients underwent sleeve lobectomy or sleeve resection of a main bronchus. Follow-up was complete except for one patient, who was no longer available for follow-up 4 years after operation. Eleven patients (7.6%) had a second primary cancer in the lung; 10 of these patients (90.9%) were men. Mean age at sleeve operation was 61.2 +/- 11.6 years. Mean interval between sleeve operation and development of second primary cancer was 53.8 months (range, 6 to 197 months). All second primary cancers occurred on the contralateral side. In five cases there was squamous cell carcinoma, in two there was adenocarcinoma, in one there was adenosquamous carcinoma, in two there was small cell carcinoma, and in one patient no definite histologic type could be established. Five patients had different histologic type from the initial, resected
primary tumor
. Seven patients (64%) were operated on: five underwent lobectomy and two underwent segmentectomy. In one patient the tumor was judged to be unresectable. Chemotherapy was given to the two patients with small cell carcinoma and radiotherapy was given to one patient with bone metastases. Follow-up was complete for these 11 patients. Data were calculated from detection of second primary cancer. There was one postoperative death from
myocardial infarction
. Eight other patients died during follow-up: five died of recurrent tumor or metastases, two died of acute cardiac failure, and one died of a perforated ulcer. The 1- and 4-year actuarial survivals were 41% and 30%, respectively. For the patients operated on, 1- and 4-year survivals were 57% and 43%, respectively. There were no survivors at 5 years. Sleeve resection is a valuable method of preserving functional lung tissue. It offers a chance of subsequent resection in patients who have second primary cancer, with acceptable results.

Between June 1988 and January 1980, 67 patients with pathologic stage III non-small cell lung cancer were randomized to receive either preoperative mitomycin, vinblastine, and cisplatin (MVP) chemotherapy (cisplatin 120 mg/m2, and mitomycin, 8 mg/m2 day 1 + 29, and vinblastine, 4.5 mg/m2 on day 1, 15, 22, and 29 and 2.0 mg/m2 day 8), or preoperative radiotherapy (44 Gy in 22 fractions to the
primary tumor
and mediastinum). The purpose of this study was to identify a treatment approach that showed sufficient effectiveness and acceptable toxicity to warrant testing by prospective randomized trial against "standard" nonsurgical treatment. All patients had surgical staging of the mediastinum and had either unresectable N2 disease or T4 disease with proximal extension of disease along the pulmonary artery. Response to preoperative therapy was evaluated 8 weeks after beginning treatment and patients with complete or partial radiographic response were to undergo surgical exploration and resection if possible. Fifty-seven patients were eligible and evaluable for response. Of the 67 total patients, 3 were unavailable for follow-up, 4 were ineligible, 1 was canceled, and 2 refused all treatment after having been randomized. Of the eligible and evaluable patients, 49 had stage IIIA and 8 had stage IIIB disease. Randomization was to MVP in 26 cases and to radiotherapy (XRT) in 31. Radiographic response to treatment was virtually identical for the two approaches, with 29 of the 57 evaluable patients achieving objective responses. In patients achieving radiographic response, 24 underwent surgical exploration and 20 underwent resection, of which 18 were complete. The mediastinum was free of tumor in seven patients but only two pathologic complete responses were seen (one each to XRT and MVP). In addition, ten nonresponders underwent surgery; seven underwent resection. Median survival for the entire group is 12 months, with a 27% actuarial survival at 4 years. Two patients died of treatment toxicity during preoperative therapy. Overall toxicity included 2 preoperative toxic deaths and 6 postoperative deaths in 34 patients who underwent surgical exploration (3 each with XRT and MVP) due to adult respiratory distress syndrome (3),
myocardial infarction
(1), pulmonary edema (1), and esophageal fistula (1), for an overall death rate 8 of 57 (14%) and a perioperative death rate in surgically explored patients of 6/34 (18%). These preoperative regimens, in the population studied herein, were of modest efficacy and substantial toxicity.(ABSTRACT TRUNCATED AT 400 WORDS)

A circular focus of 1 cm diameter was discovered by chance on a thoracic x-ray of a female patient of 66 years of age suffering from chronic interstitial nephritis due to analgesics. Bronchoscopic suction revealed histologically a small-cell carcinoma of the lung but there was no indication of formation of metastases. The patient refused any tumor-specific treatment. In the further course of the disease the focus showed up radiologically for seven months and was then no longer visible throughout the following 14 months. The patient finally died subsequent to an extensive posterior
myocardial infarction
. Postmortem examination excluded the presence of a
primary tumor
of the lung or metastases. Our case suggests the rare occurrence of a spontaneous regression of a small-cell bronchial carcinoma. Although spontaneous regression of malignant diseases is ascribed to immunological factors, such regression can also occur if the immunological system is impaired, as had been the case in this particular patient with chronic renal insufficiency.

Tamoxifen is a nonsteroidal antiestrogen that has become the frontline endocrine therapy for all stages of breast cancer. The drug is the only single-agent therapy that, when used in an adjuvant fashion, produces a survival advantage in postmenopausal women. Survival is longer when the estrogen receptor content of the
primary tumor
is higher, although receptor-poor patients still have a survival advantage from adjuvant tamoxifen equivalent to that noted with combination chemotherapy. The added advantages of tamoxifen are a maintenance of bone density and a decrease in fatal
myocardial infarction
. Although side effects from tamoxifen are few, patients must be examined for preexisting endometrial carcinoma before beginning drug use. Tamoxifen does not prevent the growth of endometrial tumors. Spotting and vaginal bleeding in postmenopausal patients taking tamoxifen should be followed up with a thorough gynecological examination. The incidence rate of endometrial cancer for tamoxifen-treated patients is 2 per 1000 patients per year. More than 80% of detected endometrial tumors are stage 1 disease and can be cured by hysterectomy.

Primary neoplasms of the cardiac valves are extremely rare. However, papillary fibroelastoma is the third most common
primary tumor
of the heart [Ann Thorac Surg 52 (1991) 1127]. These tumors can be found anywhere in the heart, but most commonly involve the cardiac valves [Ann Thorac Surg 52 (1991) 1127; McAllister HA, Fenoglio JJ. Tumors of the cardiovascular system. In: Atlas of tumor pathology, 2nd series, vols. 1-3. Washington (DC): Armed Forces Institute of Pathology; 1978. p. 20-5]. Most papillary fibroelastomas do not cause symptoms and are usually incidental findings by routine echocardiography or at autopsy. However, early diagnosis of this condition is important, since it represents a surgically correctable cause of systemic emboli, stroke,
myocardial infarction
, and sudden cardiac death [Ann Thorac Surg 52 (1991) 1127; Ann Thorac Surg 68 (1999) 1881; J Am Soc Echocardiogr 9 (1996) 353; Tex Heart Inst J 22 (1995) 327; Tex Heart Inst J 26 (1999) 298]. The echocardiographic findings should be confirmed by histology, since the clinical differential diagnosis includes myxoma, vegetation, thrombi, lipoma, and pseudopapillary fibroelastoma [Tex Heart Inst J 26 (1999) 298; J Am Soc Echocardiogr 11 (1998) 92; J Natl Med Assoc 87 (1995) 68]. Review of the literature reveals that multiple papillary fibroelastomas are extremely rare [Am Heart J 125 (1993) 1443; J Am Soc Echocardiogr 7 (1994) 315; Ann Thorac Surg 48 (1989) 119]. Li Manduri et al. [J Am Soc Echocardiogr 7 (1994) 315] reported multiple masses on the tricuspid valve, the larger of which was 1 cm in diameter. De Virgilio et al. [Ann Thorac Surg 48 (1989) 119] reported a case of multiple 1-cm papillary fibroelastomas located on mitral valve, left ventricular outflow tract, and along septum. We report an unusual case of multiple papillary fibroelastomas in a woman, who initially was admitted because of a shortness of breath and recent cerebrovascular accident.

Portal vein thrombosis refers to an obstruction of blood flow in the portal vein; this rare disease can be both local and systemic. Local risk factors, accounting for about 70% of cases, can be abdominal cancers, inflammatory of infective diseases, surgical procedures or cirrhosis. A 62-year-old man, affected by hypertension and taking acetylsalicylic acid after a
myocardial infarction
in 1994, developed deep venous thrombosis on the right leg. Six months later the patient was admitted to the emergency unit due to abdominal pain. A CT scan revealed the presence of a complete splanchnic vein thrombosis and a
primary tumor
on the right kidney. The patient was treated with total parenteral nutrition and intravenous solution of heparin sodium first and then, because of occurrence of allergy, fondaparinux, with improvement of the abdominal pain. Subsequently he underwent right radical nephrectomy.

The prognosis for brain metastasis from primary esophageal or gastric cancer is often poor because of late detection and a lack of effective treatments. We encountered two cases of long-term survival after resection of brain metastasis that was detected >1 year after primary esophagogastric junction adenocarcinoma resection. Both patients underwent total gastrectomy, middle to lower esophagectomy, and Roux-en-Y reconstruction using the jejunum, and intrathoracic anastomosis was performed via right thoracotomy and laparotomy for
primary tumor
resection as well as brain metastasis resection followed by CyberKnife irradiation. They remained recurrence free-one remains alive after 6.5 years, while the other died of
myocardial infarction
4 years after surgery. The present cases emphasize that long-term survival in patients with brain metastasis from gastric cancer can be expected after resection and stereotactic radiosurgery of brain metastasis detected >1 year after the resection of primary gastric adenocarcinoma.

Metastatic tumors are the most common tumors affecting the heart. Primary tumors are rare, with myxomas being the most common of the primary cardiac tumors. The incidence of primary cardiac tumors is 0.02%, about 200 cases has been reported in 1 million autopsies. Most of primary cardiac tumors have been detected incidentally on diagnostic modalities: computed tomography (CT), cardiac magnetic resonance imaging (MRI), or echocardiography. Majority of primary-origin cardiac tumors are benign, of which the most common type of
primary tumor
is cardiac myxoma. Fibroelastoma is a rare benign tumor and the 2nd most common cause of primary cardiac tumors. In the past fibroelastoma has been detected on autopsy findings. With the development of more advanced imaging modalities fibroelastoma is more frequently detected as a cause of stroke,
myocardial infarction
(MI), angina episodes, and systemic embolization. Echocardiogram is the best diagnostic modality to diagnose primary cardiac tumors although transthoracic echocardiogram (TTE) can miss primary cardiac tumors; transesophageal echocardiography (TEE) has been more labeled more accurate in the diagnosis of primary cardiac tumors. We present here a case of a 21-year-old male with the history of multiple strokes secondary to cardiac papillary fibroelastoma (CPF).
