Alpha-1 antitrypsin (AAT) and alphafoetoprotein (AFP) in sera of patients with germ-cell neoplasms: value as tumour markers in patients with endodermal sinus tumour (yolk sac tumour).

Serum alphafoetoprotein (AFP) and serum alpha-1 antitrypsin (AAT) were determined in 24 patients with germ-cell neoplasms of the gonads and extragonadal sites and in two patients with hepatocellular carcinoma. In the majority of the patients serial determinations were performed. All seven patients with testicular seminoma and four patients without evidence of active disease had normal levels of serum AAT and AFP. The remaining 13 patients with germ-cell neoplasms had tumours containing endodermal sinus tumour (yolk-sac tumour) elemetns. All these 13 patients had elevated levels of serum AFP and the levels were high or very high in most cases. Nine of these 13 patients had raised serum AAT, although the elevation above normal levels was only slight in a number of cases. When serial determinations were performed serum AAT levels frequently followed the pattern of serum AFP levels, but the AAT levels were frequently within normal limits and therefore the interpretation of the results was difficult, and much less reliable as compared with those for serum AFP. The elevation of serum AAT levels following the recurrence of the tumour was found to occur much later and was much less marked than elevation of serum AFP, which occurred early, showed a large rise and was a reliable marker of tumour recurrence in patients with germ-cell neoplasms containing endodermal sinus tumour elements. It is therefore considered that, although there is good evidence that serum AAT is produced by endodermal sinus tumour elements, serum AAT is not a useful monitor of disease activity in these patients, especially when compared with serum AFP, the value of which is well recognized. Serum AAT may be a useful tumour marker in patients with hepatocellular carcinoma, and this aspect should be investigated further.

Muscle changes in rheumatoid arthritis. A review of the literature with a study of 100 cases.

Muscle changes were studied in biopsy material obtained from 100 patients suffering from classical rheumatoid arthritis. The abnormalities consisted of denervation atrophy of type II muscle fibres, degenerative changes in the sarcoplasm including presence of nemaline rods, and changes within the interstitium: namely perivascular nodular myositis, lymphocytic accumulations, different stages of vasculitis and abnormalities within the intramuscular nerves and muscle spindles. The muscles examined were always severely affected. It is considered that the simultaneous presence of these abnormalities is suggestive of rheumatoid arthritis. The importance of histochemical studies is emphasized. The literature concerning muscle changes in rheumatoid arthritis is reviewed.

Mixed germ cell-sex cord stroma tumor of the ovary associated with isosexual precocious puberty in a normal girl.

A case of mixed germ cell-sex cord stroma tumor occurring in a normal 8-year-old girl with 46XX karyotype is reported. The child presented with evidence of isosexual precocious puberty 3 years prior to the excision of the tumor. Although the tumor was known to be present at least 2 years prior to its excision and weighed more than 1 kg, there was no evidence of involvement of the adjacent organs or metastases at the time of excision. The contralateral ovary was normal. The endocrine activity abated following the excision of the tumor and the patient is well and free of disease 2 years after the operation. The literature concerning this entity is discussed and reviewed.

Primary carcinoid tumor of testis.

A case of pure, primary testicular carcinoid tumor in a forty-four-year-old male is reported. The patient presented with painless testicular enlargement, and testicular tumor was diagnosed. Orchiectomy was performed, and histology revealed a primary argentaffinoma. The patient is well and symptom free two years after diagnosis.

Alpha-foetoprotein and carcinoembryonic antigen in germ cell neoplasms.

Serum alpha-foetoprotein (AFP) and serum carcinoembryonic antigen (CEA) levels were measured, serially whenever possible, in 70 patients attending the Institute of Radiotherapy, Rotterdam, on account of testicular (65) or ovarian (4) germ cell tumours or, in one case, an endodermal sinus (yolk sac) tumour in the mediastinum. In 15 patients the disease was active; in the others it was in remission. Patients with active disease had raised serum AFP levels which correlated well with disease activity; no patient without evidence of active disease had raised serum AFP levels. None of the patients with active disease was found to have raised serum CEA levels. There was no correlation between serum AFP and CEA levels in patients with germ cell neoplasms, but good correlation between serum AFP levels and disease activity. Serum CEA levels did not correlate with disease activity, and serial determinations would therefore not be useful in monitoring progress in this group of diseases.

Primary malignant lymphoma of the testis associated with sclerosis and nodularity.

A case of primary malignant lymphoma of the testis associated with an unusual degree of sclerosis and nodularity is reported. The patient, a 21-year-old male, is alive and well 5 years after orchidectomy followed by radiation therapy to the lumbar and para-aortic lymph nodes in spite of very extensive involvement of the testis, epdidymis and presence of tumour deposits within the spermatic cord and in para-aortic lymph nodes. It is suggested that sclerosis and nodularity may be favourable prognostic features in patients with primary malignant lymphoma of the testis.

Acute carcinomatous myopathy associated with ovarian carcinoma.

A case of acute, fatal, rapidly progressive pure myopathy associated with ovarian carcinoma is described. The first symptoms of carcinomatous myopathy occurred 8 months after surgical treatment and combined chemotherapy. The patient died 2 months after onset of myopathy. The clinical and pathologic findings of the myopathy are discussed.

Myocardial lesions subsequent to roentgenotherapy.

The myocardium was studied for changes caused by therapeutical X-ray irradiation in a necropsy material of 14 cases. The lesions found in the myocardial vessels, in the parenchyma and in the interstitium are described in detail. While the severity of the vascular changes was independent of the radiation dose, the gravity of parenchymal lesions was closely related to the dose employed.

The incidence of yolk sac tumor (endodermal sinus tumor) elements in germ cell tumors of the testis in adults.

The incidence of yolk sac tumor (endodermal sinus tumor) elements was studied in 147 germ cell neoplasms of the testis in adults observed over a 4 1/2-year period. Excluding 79 cases of pure seminoma, yolk sac tumor elements were found in 26 (38%) of 68 tumors; in 8 tumors the yolk sac tumor was the predominant element. Yolk sac tumor elements were found admixed with all other germ cell tumor elements. Tumors composed entirely of yolk sac tumor were not encountered. Fifteen (57%) of the 26 patients with tumors containing yolk sac tumor elements have died of their disease during the period under study, compared with 13 (31%) of the remaining 42 patients, suggesting that the prognosis of adults with testicular tumors containing yolk sac tumor elements is unfavorable. This is in contrast to the relatively good prognosis of infants and young children with testicular yolk sac tumor, and similar to the prognosis of female patients with ovarian yolk sac tumor. The results of the present study give further support to the view that yolk sac tumor (endodermal sinus tumor) is not adistinctive neoplasm of the infant's testis, but a germ cell neoplasm differentiating in the direction of yolk sac or vitelline structures, and occurring in the testis, ovary and extragonadal sites in common with other germ cell neoplasms.

Gonadoblastoma associated with embryonal carcinoma in an anatomically normal man.

A case of gonadoblastoma associated with embryonal carcinoma in a normally decended testis of an anatomically normal 20-year-old man is reported. The patient had enlargment of the supraclavicular lymph nodes, which contained metastatic yolk sac tumor. Pulmonary and abdominal metatases were present. Despite chemotherapy and radiotherapy the patient died 9 months after presentation. Review of the literature concerning gonadoblastoma in phenotypic male patients is presented.
