Heat production rate in blood lymphocytes as a prognostic factor in non-Hodgkin's lymphoma.

The heat production rate in peripheral blood lymphocytes was evaluated by direct calorimetry in 76 untreated adults with non-Hodgkin's lymphoma (NHL). Elevated values were recorded for 20 out of 54 patients with lymphomas of high or intermediate malignancy grade (37%) and for 1 out of 22 patients (5%) with low grade lymphomas (p = 0.01).

Flow cytometry in primary breast cancer: improving the prognostic value of the fraction of cells in the S-phase by optimal categorisation of cut-off levels.

The use of continuous prognostic variables is clinically impractical, and arbitrarily chosen cut-off points can result in a loss of prognostic information. Here we report findings from a study of primary breast cancer, showing how the prognostic value of the fraction of cells in the S-phase of the cell cycle (SPF), as measured by flow cytometry, can be affected by the SPF cut-off level(s) adopted. It was possible to evaluate the SPF in 566 (94%) of 603 consecutive cases where fresh frozen specimens were available in a tumour bank at our department.

Indicators of prognosis in node-negative breast cancer.

Measures of the proliferative activity of tumor cells have prognostic value in patients with node-negative breast cancer. We studied 367 women in southern Sweden who had undergone surgical resection for such cancer. Tumor specimens were analyzed with DNA flow cytometry in order to estimate both the DNA content (ploidy) and the fraction of cells in the synthetic phase of the cell cycle (S phase).

The Alvik glenoplasty for the unstable shoulder. Modification of the Eden-Hybbinette operation in 66 cases.

66 shoulders treated with the Alvik modification of the Eden-Hybbinette operation for recurrent anterior dislocation or subluxation were examined with an average follow-up of 6 years. Two shoulders had redislocated and one had subluxations. Forty-five of the 57 cases radiographically examined showed bony healing of the transplant; nonunion of the transplant occurred in 6 cases and resorption in another 6.

Deletion of 14q in non-Hodgkin's lymphoma.

6 patients with non-Hodgkin's lymphoma [3 with small cell lymphocytic lymphoma of B-cell type (SL), and 1 each with follicular centroblastic/centrocytic, centroblastic, and immunoblastic lymphoma] and with the acquired cytogenetic abnormalities del(14) (q22) or del(14) (q24) are described. An evaluation of these 6 cases and 41 other lymphatic neoplasms with 14q deletion known from the literature revealed that 37 had a breakpoint in bands q22 to q24. The deletions occur significantly more often in lymphomas of SL morphology and in the leukemic counterpart, chronic lymphocytic leukemia, than in other types of lymphatic malignancies (p less than 0.

Mitotic activity and survival in advanced non-Hodgkin's lymphoma of unfavourable histology.

The number of mitoses per high power field (mitotic index, MI) was assessed in 2 microns sections of lymph node biopsies from 58 adults with non-Hodgkin's lymphoma. All had diffuse nodal lymphomas of unfavourable histology and stage II-IV disease. The patients were treated with chemotherapy and followed for a minimum of 3 years or until death.

Diadenosine tetraphosphate (Ap4A) levels in HL-60 cells during differentiation into granulocytes and monocytes.

1. Diadenosine tetraphosphate (Ap4A) levels were determined in HL-60 cells differentiating into granulocytes or monocytes after treatment for 0-7 days with retinoic acid (RA) or 4-beta-phorbol-12-myristate-13-acetate (PMA) respectively. 2.

Late age at first full-term pregnancy as a risk factor for women with malignant lymphoma.

Women with malignant lymphoma, non-Hodgkin's lymphoma and Hodgkin's disease were of a significantly later age at first full-term pregnancy (AFFP) than controls without malignant disorders. The odds ratio (OR) of having the first pregnancy at 30 years of fertility was 6.4 for women with malignant lymphoma.

Estrogen and progesterone receptor analyses in more than 4,000 human breast cancer samples. A study with special reference to age at diagnosis and stability of analyses. Southern Swedish Breast Cancer Study Group.

Estrogen (ER) and progesterone receptors (PgR) were measured in the same laboratory in more than 4,000 breast cancer biopsy samples obtained from 15 different hospitals during ten years. ER was measured with isoelectric focusing and PgR with the dextran-coated charcoal method and Scatchard analysis. The distribution pattern for both ER and PgR was during this time period and for the different hospitals rather similar indicating a good stability of the analytical methods.

Influence of "nuclear" estrogen receptor content on prognosis of early stage carcinoma of the uterine body. A short-time follow-up.

Sixty-five patients with Stage I and II endometrial carcinoma were investigated. After a short-time follow-up (17-24 months) significant differences in frequency of relapses were observed between patients with tumors containing low amounts of estrogen receptor (ER less than 60 fmol/mg DNA) in the nuclear pellet, and those with tumors containing greater than 60 fmol ER/mg DNA (p = 0.01).

Rising incidence of breast cancer among young women in Sweden.

The national Swedish cancer registry was used to analyse the age-specific time trends in breast cancer incidence in Sweden from 1970 to 1984. The analysis included both a calendar year and a birth cohort approach to estimate time trends in disease occurrence. According to the birth cohort approach there was a statistically significant increase in the incidence with an average annual increase of the incidence of 3.

Increased plasma prolactin levels in a group of men with breast cancer--a preliminary study.

Gonadal and hypophyseal hormones were investigated in 15 males with breast cancer and 15 tumour referents, on average 1 month postoperatively. Plasma prolactin was found to be significantly more often elevated in men with breast cancer compared with referents (p less than 0.005).

Personal hygiene in external genitalia of healthy and hospitalized elderly women.

A comparative study of the personal hygiene of two groups of elderly women was carried out in Orebro, Sweden. The investigation group consisted of 28 women who were hospitalized in long-term care wards and the comparison group consisted of 35 healthy women. The results show that a remainder of soap in the genitalia may be one factor contributing to elderly hospitalized women's discomfort.

Lack of care givers' knowledge causes unnecessary suffering in elderly patients.

A comparative study of the personal hygiene of two groups of elderly women was carried out. The control group consisted of 35 healthy women aged 70-86. The experimental group consisted of 28 women aged 66-96 who were hospitalized in long-term care wards and who received help with their personal hygiene.

Early oral contraceptive use and breast cancer among premenopausal women: final report from a study in southern Sweden.

In southern Sweden during the 1960s, women began to use oral contraceptives (OCs) extensively at a young age. This case-control study investigates the relationship between the use of OCs and breast cancer development in women in southern Sweden diagnosed in the early 1980s. The risk for breast cancer after OC use among premenopausal women was modeled, after adjustment was made for age, age at menarche, and age at first full-term pregnancy or parity.

Cancer incidence after cholecystectomy--a cohort study with 30 years follow-up.

Cholecystectomy has been connected with an increase in colorectal, breast and reproductive system cancers. On 472 patients, 398 women and 74 men, cholecystectomized during the years 1951 to 1955, cancer incidence was investigated. Our results show an elevated risk of breast cancer in the female group (P = 0.

Relation between occupational exposure to organic solvents and chromosome aberrations in non-Hodgkin's lymphoma.

Chromosome analysis of lymphoma cells was performed in 54 untreated patients with non-Hodgkin's lymphoma (NHL). 10 patients had a history of daily occupational handling of organic solvents for at least 1 year (exposed group) and 44 patients had never (or only for shorter periods) worked with solvents (unexposed group). There were no differences between exposed and unexposed patients regarding age, clinical stage or histologic malignancy grade.
