Possible role of mumps virus in the etiology of ovarian cancer.

Eighty-four ovarian cancer (OCa) patients and 84 controls with nonmalignant conditions matched by age and ethnic origin were interviewed with regard to clinical mumps history and their sera were tested for complement fixation (CF) mumps antibodies. OCa patients differed from the controls in the response to past mumps infection in two respects: 1) They appeared to be more likely to have developed subclinical mumps as evidenced by a lower rate of clinical mumps history in the presence of serological evidence of similar infection rates among those with positive and those with negative clinical mumps history. 2) They tended to present lower persistent mumps CF antibody titers. These results may be interpreted to indicate that an immunological incompetence enables the development of OCa possibly through a direct etiologic role of mumps virus.

Adenocarcinoma of the uterine cervix in Jewish women: a distinct epidemiological entity.

During an 11-year period, 532 Jewish women with invasive cancer of the uterine cervix were diagnosed in Israel. Of these, 441 (82.9%) had squamous cell carcinoma (SUC) and 52 (9.8%) had adenocarcinoma (AUC). Different characteristics were noted for these two histological categories with regard to age, ethnic distribution, and chronological time trends. The ratio between AUC and SUC differed considerably between the various ethnic groups, ranging from about 1:6 in the Asian and European born to less than 1:14 in the North African. This indicates that the relatively higher incidence of AUC in Israeli Jewish women is limited to those ethnic groups that have a low risk for cervical cancer. The different patterns of SUC and AUC in the population support the contention of a varying etiology.

Attempted induction of granulosa cell tumor in Balb-C mice by gonadotropin administration.

An attempt of granulosa cell tumor (GCT) induction by prolonged administration of exogenous pregnant mare's serum gonadotropin (PMSG) to young, mature, and middle-aged Balb-C mice resulted mainly in stromal luteal cell proliferation. 48.9% of young mice, 64.5% of mature mice and 65% of middle-aged mice developed luteal cell proliferation. This effect seemed to be dependent on duration of treatment, mainly in young mice. Young mice injected for less than 6 months developed significantly less luteal cell proliferation than those injected for more than 6 months. Only 1 GCT was found. This study seems to support the contention that besides gonadotropin stimulation, other factors may be involved in GCT development. A large number of PMSG-injected mice developed generalized lymphosarcoma, the mechanism of which remains unknown.

Lymphocytic infiltration in endometrial adenocarcinoma. Correlation with histologic differentiation, clinical staging and prognosis.

Lymphocytic infiltration in endometrial adenocarcinoma was evaluated in curettings from 50 patients and correlated with histologic differentiation, clinical staging and prognosis. In spite of the absence of any significant correlation between lymphocytic infiltration and the various parameters investigated, the presence of a marked infiltrate in 46% of the cases suggests that in endometrial adenocarcinoma, as in other neoplasms, a cell-mediated immune response does indeed exist, but warrants further investigation by more refined methods.

Antibodies to Herpes simplex virus in Jewish women with cervical cancer and in healthy Jewish women of Israel.

Herpes simplex virus (HSV) antibody titers were examined in sera from 39 Jewish women with squamous cell carcinoma of the uterine cervix (CaCx) and in sera from controls matched by age and country of origin. Highly significant differences were found between the cases and controls for both HSV type 1 (HSV-1) and HSV type 2 (HSV-2). Compared to findings in other demographic areas, the geometric mean titer (GMT) of HSV-1 among the CaCx cases were considerably higher, whereas the GMT for HSV-2 was in the same range. The percentage of HSV-2-positive patients, as defined by the HSV-2/HSV-1 antibody titer ratio was low compared to that found in other demographic areas; this was presumably due to the high incidence of HSV-1 infection in the population. The HSV-1 and HSV-2 infection rate in the Israeli Jewish female population was estimated by antibody titers for 94 healthy subjects. The GMT of HSV-1 was considerably higher, whereas the GMT of HSV-2 was lower, than those reported elsewhere. The association found previously between HSV-2 and CaCx remained true for Jewish women. Their low incidence of CaCx, which did not seem to result from lower susceptibility, might be explained by the low incidence of HSV-2 infection.
