Dysgerminoma associated with pregnancy.

From a review of 26 reported case (our case being the 27th) of dysgerminoma associated with pregnancy, several salient facts are evident. Torsion and incarceration are common among these rapidly enlarging tumors. Obstetrical complications occurred in nearly half and fetal demise in one quarter of the reviewed cases. Our case was typical of patients presenting with this vexed problems: The patient was under 25 (as were 70%); nulliparous (as were 67%); and the tumor appeared confined to one ovary (as in 89%). Authorities are in dispute as to the treatment of stage IA dysgerminomas, and the association of pregnancy complicates this debate even further. The results of conservative treatment in this series were jarring: There were recurrences in 30% of the 23 stage IA tumors, and the recurrences were all following unilateral oophorectomy. In our case, the grossly normal contralateral ovary was infiltrated with dysgerminoma cells. While treatment of a young woman with a dysgerminoma of 1 ovary is a matter of perplexity, we believe that a unilateral operation should be limited to those women who desire above all earthly things to retain their childbearing capacity.

A case of mixed-type dysgerminoma with a high serum concentration of both human chorionic gonadotropin and alpha-fetoprotein in a child.

Dysgerminoma is divided into two types: pure and mixed. The mixed type is related to other various elements of germ cell tumors. We experienced a case of mixed type dysgerminoma with a high serum concentration of both human chorionic gonadotropin and alpha-fetoprotein. The patient was a 6 year old girl who was admitted to the Hamamatsu University School of Medicine with an abdominal mass. Laboratory investigations revealed elevated serum alpha-fetoprotein and high concentration of serum beta-human chorionic gonadotropin. The tumor originated from the left ovary. The histopathological diagnosis was dysgerminoma. Serum human chorionic gonadotropin and alpha-fetoprotein levels were useful markers in monitoring the response to treatment in this patient.

Ataxia-telangiectasia with ovarian gonadoblastoma and contralateral dysgerminoma.

Although neoplasms are unusually frequent in patients with ataxia-telangiectasia, the occurrence of primary tumors of the ovary in such patients is exceedingly rare. This report describes a 17-year-old phenotypic female with ataxia-telangiectasia, who was found to harbor an ovarian gonadoblastoma and a contralateral dysgerminoma. The latter tumor has occurred in only one other patient with ataxia-telangiectasia, while an association with gonadoblastoma has never been documented previously. Additional unusual features rarely encountered in patients with gonadoblastoma included origin of the tumor within a histologically proven ovary, and a 46,XX karyotype. The possibility that the dysgerminoma also arose from a gonadoblastoma is discussed.

Anaplastic dysgerminoma.

A rare case of rapidly evolving dysgerminoma produced death by tumor in less than two months after onset of symptoms. It is important to recall that dysgerminoma possesses considerable malignant potential, which infrequently is manifested by rapidly progressive disease. Certain risk factors, present in the pathological specimen, serve to indicate the aggressive potential of such neoplasms.

Dysgerminoma of the ovary: radiation therapy for recurrence and metastases.

Nine cases of dysgerminoma are reported. Five patients developed recurrence of disease in either the pelvis or metastatic sites including the lung and brain. The metastatic disease was controlled by a radiation dose of 2,000 to 3,000 rads during three to four weeks in four of the patients. The excellent response of dysgerminoma to radiation warrants an optimistic prognosis and vigilant follow-up since metastatic disease can be controlled by moderate radiation doses.

Dysgerminoma in Turner's syndrome.

The importance of the Y-chromosome for the germ cell tumour development in gonadal dysgenesis has been emphasized many times. In contrast, only two cases of dysgerminoma or gonadoblastoma had been published so far in the XO-Turner's syndrome. With this report, another case of Turner's syndrome developing a dysgerminoma in a gonadal streak is presented. No Y-chromosome containing stemline could be detected in the patient nor in the tumour. A primary genetic etiology or a mechanism related to early secondary regression or dysgenesis of the gonad are discussed as causative factors in germ cell tumour development within gonadal streaks.

Lymphography in the staging, treatment planning, and surveillance of ovarian dysgerminomas.

Ovarian dysgerminomas are distinguished from other ovarian neoplasms by their rarity, their predilection for metastases via lymphatic pathways, and their radiosensitivity and favorable prognosis. After the initial surgery, which provides the histologic diagnosis and defines the local extent of pelvic involvement, lymphography is the single most useful tool to determine whether retroperitoneal lymph nodes are involved. Results of the study guide the radiotherapeutic approach, including field size and dosage. In an unselected group of 31 previously untreated patients, 10 had positive lymphograms. The response to therapy and the detection of relapse of disease may be evaluated by monitoring the residually opacified lymph nodes with surveillance abdominal radiographs. If necessary, a repeat lymphogram can be performed. The 2 year survival rate of 84% for ovarian dysgerminomas is lower than that for testicular seminomas, probably due to later recognition of the tumor. Failuresare related to local extension or to hematogenous dissemination.

Dysgerminomas (seminomas) in genetic males with female phenotype. One case of gonadal dysgenesis and gonadoblastoma and one of testicular feminization.

Gonadal tumors in patients with somatosexual ambiguity are rare but of considerable clinical and pathological interest. Two patients with dysgerminomas and abnormal sexual differentiation were recently treated at the Department of Gynecologic Oncology. One (Case 1) was an 18-year old girl and the other (Case 2) an unmarried woman of 58 years. In spite of their female phenotype both showed a male genotype, 46, XY. In Case 1 the dysgerminoma (or rather seminoma) originated in a gonadoblastoma in one of two dysgenetic testes but in Case 2 in one of two "feminizing testes". The clinico-pathological features of both cases will be reported and commented and the relation between the germ cell tumors, gonadal dysgenesis and the Y-chromosome will be discussed.

The treatment for dysgerminoma of the ovary.

Thirty-six patients with pure dysgerminoma of the ovary were treated at the University of Texas System Cancer Center, M.D. Anderson Hospital and Tumor Institute between 1947 and 1974. Twenty-six of these patients had their initial surgery at the M.D. Anderson Hospital or were referred to the M.D. Anderson Hospital shortly after surgery at another hospital. The remaining 10 were referred after developing a recurrence of their tumor. Five of the 26 patients who were treated initially at the M.D. Anderson Hospital had only a unilateral salpingo-oophorectomy and are alive and well at the present time. The remaining 31 patients have received postoperative radiotherapy. Ninety-two percent of the patients receiving initial treatment at M.D. Anderson Hospital, and seventy percent of those referred for treatment after recurrence, are surviving at the present time without evidence of disease. The selection of treatment for the individual patient is discussed.

Dysgerminoma of the ovary.

From 1938 to 1977, 21 patients with pure dysgerminoma were treated at Memorial and James Ewing Hospitals, now Memorial Sloan-Kettering Cancer Center. Twelve patients were considered to have their initial therapy begun or completed at our institution. Eleven (91.7%) of 12 patients were found free of disease from 2 to 38 years (median 6 years). Nine patients were referred with recurrent disease. Only 4 (45%) could be salvaged 2 to 21 years (median 9 years). Because of the lower survival rate in the treatment of recurrent disease in this series, it is difficult to advocate overly conservative therapy initially in all early lesions. The survival rate depends on the original size of the tumor, initial adequate staging and appropriate therapy based on the extent of disease. Recommendations for a treatment protocol are proposed.

[Gonadoblastoma and overgrowing dysgerminoma in Turner mosaicism [45, XO/46, Xi (Xq)] (author's transl)].

It is well established that the Y-chromosome is associated with germ cell tumor development. There is a considerable tumour risk in XY- and XY/XO-gonadal dysgenesis. In the absence of Y-chromosome germ cell tumours are extremely rare. The history of a patient with 45 XO/46 Xi (Xq)-karyotype is presented, who had a gonadoblastoma with overgrowing dysgerminoma. According to basal body temperature recordings, this patient ovulated up to the age of 22 years. After this cyclical ovarian function was exhausted; histologically no primordial follicles could be detected. Gonadotropin as well as prolactin binding sites in the tumours could not be demonstrated, suggesting hormone independency and complete malignant transformation of the tumor. In general the clinician should be aware of a possible germ cell tumour development in the absence of a Y-chromosome. However as far as the clinical management of patients with dysgenetic gonads is concerned, prophylactic gonadectomy is only indicated in the presence of a Y-chromosome.

A review of thirty-three cases of ovarian dysgerminoma emphasising the role of radiotherapy.

The records of 33 cases of ovarian dysgerminoma seen in Manchester between 1943 and 1977 are reviewed, including details of presenting features, age distribution, treatment and survival. The five-year survival rate is 85%. All the Stage I cases and all patients under the age of 20 years at presentation have survived. The cases of the five patients who died are analysed in detail. From this series and review of other series it is concluded that young patients with unilateral Stage I desease who have had a total resection should be carefully followed and radiotherapy reserved for recurrent disease. This does not appear to affect their high chance of cure and enable patients who remain disease-free to retain one functioning ovary. All other patients should have surgery followed by radiotherapy to the whole abdomen. Analysis of the five deaths suggested that, even in Stage III disease a surgical attempt should be made to remove the bulk of the tumour and that the abdominal radiotherapy dose should not be less than 3000 rad in 20 treatments in 28 days.

Intracranial dysgerminomas.

We have reported three cases of intracranial dysgerminoma. The origin of these tumors has been controversial for a long time. It is now accepted that they develop from germ cells. The diagnosis is often difficult to confirm because of the varity of signs. If their origin is now accepted, the best way to deal with these lesions is still controversial. They can be macroscopically removed if they are in the pineal region. Such treatment is not possible for suprasellar tumors. Since these tumors can metastasize, radiation should be administered as soon as a pathological diagnosis is obtained. It is our belief that it should be administered to the whole spinal axis.

Hypertrophic osteopathy and dysgerminoma in a mare.

A case of hypertrophic osteopathy is described in a mare with a vague history of abdominal discomfort over the preceding 12 months. Bony swellings were obvious in the pastern area of both forelegs. There was a dysgerminoma of the left ovary that had metastasised to several abdominal lymph nodes and had infiltrated the posterior vena cava. There was no gross thoracic involvement although there was histologic evidence of tumour metastasis in pulmonary arterioles.

Dysgerminoma in a rhesus monkey: morphologic and biological features.

A female Macaca mulatta was observed for 31 months after the initial surgical removal of an ovarian tumor. Solitary metastatic lesions were surgically removed 26 and 28 months after excision of the primary tumor. The animal was killed after 31 months because of additional metastatic lesions. Histological evaluation by light microscopy was not conclusive in determining the origin of neoplasm. Transmission electron microscopy, lymphocyte marker studies, and hormone assays were utilized to confirm the diagnosis of dysgerminoma.

Ovarian dysgerminoma, investigations on cell-and humoral-mediated immunologic reactions.

A 17-year-old girl with repeated ovarian dysgerminoma is described. Postoperative immunologic investigations prior to irradiation showed a transient increased cell--an humoral--mediated immunologic responsiveness of the patient for approximately 2 1/2 months. After irradiation, a markedly defective response to PHA was observed which improved when reexamined 11 months later. The patient is well 22 months after the second operation.

Ovarian dysgerminoma with embryonal carcinoma: A case report.

The association of an ovarian dysgerminoma with embryonal carcinoma in a 19-year-old woman is described. This is a highly malignant combination resulting in very rapid tumour growth and dissemination. A case report is presented and the aetiology, malignant potential and subsequent management of this most unusual tumour are discussed.

Ovarian germinomas (dysgerminomas).

The clinicopathologic findings of 13 patients with ovarian pure germinomas (dysgerminomas) were studied to assess modes of therapy. The patients' ages ranged from 12 to 40 years. Ten patients had unilateral tumors clinically confined to the ovary (Stage I), including 1 patient who had an unsuspected microscopic germinoma in a normal-appearing ovary. Of those with Stage I tumors, only 1 patient developed metastases and died; however, the presence of other elements in the mestases suggested that her primary ovarian neoplasm actually may have been a malignant mixed germ cell tumor. The other 9 patients are alive without tumor after postoperative intervals of 0.3 to 29 years. Three patients had more advanced lesions (Stages II-IV) and 2 died of metastases following orthovoltage irradiation. The results of this study support the concept of individualized therapy for patients with ovarian germinomas.
