Eight cases of well-differentiated, intramedullary osteosarcoma were studied. In three cases, the lesions previously had been diagnosed, pathologically and radiologically, as benign. The distal femur was the most frequent site. Radiographically, the tumor margins were poorly defined in five cases and were well defined in three. In seven cases, the bone response pattern was both lytic and blastic; in one case, it was purely lytic. Tumor matrix patterns were mostly homogeneous and cloudlike. Four of the lesions were expansile. All cases had cortical thinning and discontinuity. Extraosseous involvement of the soft tissues was present in six cases, and active periosteal response was present in two. High-grade malignancies subsequently developed in two patients--one was a local recurrence and the other was a distant metastasis. A broad spectrum of radiologic features was observed in well-differentiated intramedullary osteosarcomas, but all cases had at least two of three radiographic findings (cortical discontinuity, poorly marginated soft-tissue extension, or cloudlike tumor matrix pattern) that strongly suggested malignancy.

Seventeen patients treated for acute lymphoblastic leukemia by combination chemotherapy before their reaching 10 years of age were studied for altered dental root development of their premolar teeth. Five of the 17 patients showed subjective radiographic evidence of marked shortening of the premolar dental roots; 13 had thinning of the roots. A quantitative analysis was developed and verified, which disclosed a 63.33% to 84.38% reduction of premolar root length when compared with the mean of the historical controls. With recent significant increases in long-term survival rates of children with malignancies, altered dental development becomes an important factor to follow years after chemotherapy is discontinued. The findings of these chemotherapy-associated dental development changes impacts on the patient's quality of life and also can serve as a research tool to assess permanent effects of chemotherapy on normal tissue growth and development.

Characteristic findings of depressed early gastric cancer were summarized by neoplastic histological type according to the roentgenographic findings as follows: Undifferentiated cancer: The depressed surface shows many irregular changes and granular shadows of various sizes. The depressed edge is clear and shows a coarse or small wavelike pattern. The mucosal folds of the stomach are often interrupted by the depressed edge or show sharp thinning. Differentiated cancer: The depressed surface shows very few irregular changes, and is rather squamous compared with undifferentiated cancer. The depressed edge is fine and shows a thornlike pattern. The margin shows spindle or low IIa-like protuberance findings. The mucosal folds show slight thickening at the margin and gradual thinning at the depressed site. Thus, the folds are rarely interrupted at the margin.

Twenty-six patients with metastatic colorectal adenocarcinoma were entered into a Phase I-II study of 5-fluorouracil (5-FUra)-high-dose leucovorin (CF). The starting dose of 5-FUra was 300 mg/sq m with escalation to 750 mg/sq m/week in 6 doses given by rapid i.v. injection midway during a 2-hr infusion of CF, 500 mg/sq m. Partial responses were seen in 9 of 23 patients (6 of 12 who had had previous 5-FUra). Complete normalization of liver enzymes was seen in two of these patients. Side effects were seen sporadically with 5-FUra doses up to 600 mg/sq m. At a 600-mg/sq m 5-FUra dose, 8 of 18 patients had diarrhea, and 2 of 18 had white blood cell counts less than 3000/microliter. At a 750-mg/sq m dose of 5-FUra, 6 of 11 patients had severe diarrhea and 6 of 11 had white blood cell counts less than 3000/microliter. Other toxicities were mild conjunctivitis and lacrimation, thinning of the nails, and alopecia. In bioavailability studies of CF p.o., no plasma CF could be detected. After CF i.v., mean plasma peak was 111.3 +/- 40.3 (S.D.) microM. 5-FUra-CF appears to be effective in patients clinically resistant to 5-FUra. This study is being extended to randomized trial of 5-FUra-CF versus 5-FUra alone.

Moyamoya disease was originally defined as a characteristic syndrome of recurrent headaches, occlusion of the distal internal carotid arteries and the foggy (moyamoya) clusters of collateral vessels at the base of the brain as demonstrated by cerebral angiography. The etiology is unknown and pathobiology is poorly understood. We examined the intracranial arteries in 3 patients to demonstrate characteristic changes and to obtain a better understanding of the basis mechanisms of the disease. Controls were obtained from 3 normotensive patients who died as a result of cancer. Occluded internal carotid arteries were characterized by severe thickening of the intima with a dense luminal array of smooth muscle cells, a deeper less cellular zone, pronounced tortuosity of the internal elastica and thinning of the media. Collateral vessels were arterial in structure and were affected by similar proliferative changes in the intima, thinning of the media, and contorted internal elastica. Stainable lipids were not part of the typical components. Severe contortion of the internal elastica, medial damage and intimal proliferation may result from recurrent and sustained spasticity of the cerebral arteries. The distal lenticulostriate arteries showed severe medial damage similar to what is termed as a moth-eaten change in hypertensive patients dying of massive cerebral hemorrhage.

Twenty-two patients who had metastatic breast cancer previously treated with combination chemotherapy, cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) or CMF with vincristine and prednisone, were treated with Carminomycin (carubicin) 20 mg/m2 body surface area by intravenous bolus injection once every 3 weeks. Of 21 evaluable patients, 1 patient achieved complete remission, 5 patients achieved partial responses, and 11 remained stable. Cases of acute drug toxicity included myelosuppression, phlebitis, and gastrointestinal symptoms; there were four cases of mild alopecia, which consisted of thinning of the scalp hair. There were three cases of biopsy-proven cardiomyopathy, contrary to previous reports from the United Soviet Socialist Republic, which indicated that this drug was relatively free of cardiotoxicity. The median duration of remission for responders was 23 weeks. It is believed that Carminomycin has significant activity against metastatic breast cancer and, because its side effects, especially nausea, vomiting, and alopecia, were considerably milder than those experienced with Adriamycin, further investigation of this drug is warranted.

When 58 minute gastric cancers less than 5 mm in diameter from 55 patients were classified into 22 of the single group (minute gastric cancer alone) and 36 of the multiple group (associated with other large gastric cancers), the preoperative correct diagnostic rate by x-ray was 22.7% and 11.1% in the single group and in the multiple group, respectively, with a total rate of 15.5%. The diagnostic rate by endoscopy, aided by endoscopic biopsy, was 95.5%, 13.9%, and 44.8%, respectively. Therefore, it appears that endoscopy and endoscopic biopsy are most efficient diagnostic tools for the detection of such minute gastric cancers. Since the detection of the depressed type (IIc) of minute gastric cancers is considered most significant because of their frequent submucosal invasion, their characteristic endoscopic findings are emphasized: (1) irregular and polygonal shape, (2) distinct depression, (3) clear demarcation, (4) nodular margins, and (5) moth-eaten appearance and abrupt thinning of the mucosal folds.

This investigation was designed to evaluate echoes of patients who received a course of doxorubicin (225-550 mg/m2) by two sensitive indicators of myocardial fibrosis: (1) M-mode scans of thickening-thinning curves of the left ventricular posterior wall (LVPW), and (2) two-dimensional qualitative evaluation of LVPW contraction at three levels of the LV short axis (leaflet, chordal, and papillary). These were compared to standard M-mode shortening fraction (delta S). Eighteen children with cancer were evaluated; 11 had received doxorubicin and 7 were treated with other agents. Echocardiographers were unaware of the treatment category. All controls and 10 of 11 doxorubicin patients had normal delta S. An M-mode echocardiogram of the expanded LVPW was digitized and wall thickness was evaluated by determining if diastolic relaxation had the normal two phases or only one; six of ten doxorubicin patients and no controls had abnormal relaxation. Qualitative evaluation of LVPW and septal contraction toward the center of the ventricle showed that seven of eleven patients who received doxorubicin and one control (a postthoracotomy patient) had contraction deficits. Six of seven with contraction deficit were the same patients with slowed relaxation. The greatest contraction deficit occurred in the LVPW behind the posterior mitral leaflet. Patients with more extensive involvement had an additional contraction deficit extending to the apex. These tests are more sensitive for detection of doxorubicin toxicity than delta S.

The excision of small cutaneous malignancies of the nose frequently results in defects that are appropriate for closure with a nasolabial flap. However, in the older male patient with thick nasal skin, the flap frequently undergoes the trapdoor phenomenon, producing a bulky, unsightly mass. This problem can be corrected, however, by excision of the redundant skin and subcutaneous tissue, leaving a graftable base that can be resurfaced with a full-thickness postauricular skin graft. This method of revision appears superior to just elevating and thinning the flap.

Inverted papillomas in the nose and/or paranasal sinuses exhibit a high recurrence rate, and an association with malignancy. Early diagnosis and aggressive surgical therapy are thus essential. Seventeen cases of inverted papilloma seen at Saitama Cancer Center over a 17-year period were reviewed. Common presenting symptoms, the primary papilloma sites and the results of surgical treatment were as follows. 1) Almost all patients complained of nasal obstruction. The usefulness of nasal biopsy of the tumor was confirmed, with 12 cases being diagnosed as having inverted papilloma pre-operatively. Inverted papilloma without squamous cell carcinoma caused osseous thinning, but did not destroy the bone. 2) It was found that the primary site of the papilloma involved the lateral wall of the nasal cavity. Lateral Rhinotomy was therefore recommended as a standard treatment. 3) The recurrence rate was 1/12 after Lateral Rhinotomy. Two cases had complaints associated with the Lateral Rhinotomy, nasolacrimal duct stenosis, and a scar in the median corner of eye. 4) Only one case had concomitant squamous cell carcinoma in the nose and maxillary sinus. This patient received chemo therapy, radiation therapy and finally maxillectomy, but the inverted papilloma recurred several times. Six years later, squamous cell carcinoma recurred and lead to this patient's death.
