- The number of mitoses per high power field (mitotic index, MI) was assessed in 2 νm 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. None out of 29 patients with a MI ≥ 3.0 survived for 3 years after diagnosis whereas 13 out of 29 other patients with MI <3.0 became long-term survivors (P = 0.00002). Differences in age, sex or clinical stage between short- and long-term survivors were negligible. The initial chemotherapy regimens were not more intense for the long-term survivors. Twenty-nine patients were given an equivalent initial treatment with CHOP or CHOP plus methotrexate. The association between MIs and survival was evident also in this subgroup. The results indicate that survival is extremely poor for patients with advanced diffuse nodal lymphomas of unfavourable histology and a high mitotic count. It seems especially important to evaluate alternative chemotherapy regimens, suggested to be more effective than current programmes, in this subset of patients.

- Abstract: 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). Median survival was 39 months for patients with normal values and 8.5 months for those with elevated values (p = 0.005). In a subgroup of 38 patients with high or intermediate grade NHL stage III‐IV, 17 patients with abnormally high lymphocyte heat production rates had a significantly shorter survival than 21 patients with normal values (p = 0.01). In a multivariate analysis the prognostic impact of lymphocyte heat production was superior to histologic malignancy grade, clinical stage and age.

- Southern travelling habits were recorded for 127 melanoma patients from southern parts of Sweden (the 56th latitude), 55 thyroid cancer patients, 100 non-Hodgkin's patients and 794 healthy controls from the same region. Melanoma patients were found to travel significantly more often south of the 45th latitude, as compared with patients with non-Hodgkin's lymphoma or thyroid carcinoma (RR = 2.2 for a difference of + 10 trips), and with the healthy controls (RR = 1.4 for a difference of + 10 trips). Considering men and women sepatately, the difference was significant only for men. Patients with melanoma had a higher educational level than the tumour controls and the healthy controls (p<0.001 and p<0.001 respectively). There was a significant correlation between high travelling frequency and high education. An increased risk related to southern travelling was present for patients with melanoma on the extremities and head and neck, as well as for patients with truncal melanoma. These findings support the concept that acute exposure to sunburn may be a risk factor for malignant melanoma.
