A patient with Hodgkin's disease spontaneously developed steroid-responsive hypercalcaemia during two consecutive summers. Administration of 3000 U/day of vitamin D, while he was normocalcaemic, caused a sharp increase in serum 1,25(OH)2D3 (from 59 pg/ml to 142 pg/ml) and subsequently hypercalcaemia while serum 25(OH)D3 rose moderately within the normal range (from 2.8 ng/ml to 10 ng/ml). During a spontaneous episode of hypercalcaemia which was accompanied by increased circulating 1,25(OH)2D3 concentrations, administration of hydrocortisone decreased serum 1,25(OH)2D3 rapidly (from 115 pg/ml to 62 pg/ml) and eventually led to normocalcaemia while serum 25(OH)D3 remained unchanged. Thus the disturbances of mineral metabolism found in this patient with Hodgkin's disease are very similar to those previously described in sarcoidosis.

In the autumn of 1984 there was spontaneous correction of hypercalcaemia in a patient with Hodgkin's lymphoma. Hypercalcaemia recurred when ultraviolet radiation (UVR) was given and this abnormality was associated with high serum concentrations of 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) although concentrations of precursor 25-hydroxyvitamin D3 were normal. Chemotherapy of Hodgkin's lymphoma corrected the hypercalcaemia and subsequent exposure to UVR did not produce either hypercalcaemia or a high serum 1,25(OH)2D3. Rigorous tests were applied to the putative 1,25(OH)2D3 produced during hypercalcaemia and it was not possible to separate this metabolite from 1,25(OH)2D3 itself. It is concluded that the hypercalcaemia was caused by abnormal vitamin D metabolism which was a result of the Hodgkin's lymphoma. Hodgkin's tissue may have been the site of excessive synthesis of 1,25(OH)2D3.

A 35-year-old white male with rheumatoid arthritis who had developed hypercalcemia, hypercalciuria, and nephrolithiasis was found to be abnormally sensitive to vitamin D as a result of lack of regulation of circulating 1,25-dihydroxyvitamin D (1,25-(OH)2D). An increase in daily intake of vitamin D from 10 micrograms (400 units) per day to 50 micrograms (2000 units) per day produced an abnormal elevation in serum 1,25-(OH)2D, hypercalcemia, and hypercalciuria which were corrected by prednisone. Serum 25-hydroxyvitamin D initially was abnormally low, and increased with vitamin D to values which were in the low normal range. There were significant positive correlations between serum 1,25-(OH)2D (p less than .05) and serum calcium and between serum 1,25-(OH)2D and urinary calcium (p less than .05). Serum immunoreactive parathyroid hormone, initially in the lower range of normal, decreased further during hypercalcemia. A radiograph of the chest, gallium scan, and serum angiotensin-converting enzyme activity were normal. No granulomas or evidence of lymphoma were found in biopsies of the liver and of several lymph nodes. It is concluded that the abnormal calcium metabolism in this patient resulted from increased circulating 1,25-(OH)2D and that the defect in vitamin D metabolism was not related to sarcoidosis, other granulomatous disease, Hodgkin's disease, or lymphoma. The relationship, if any, of the abnormal metabolism of vitamin D and calcium to rheumatoid arthritis remains to be established.

High serum concentrations of 1,25-dihydroxyvitamin D [1,25-(OH)2D] can occur with hypercalcemia in malignant lymphoma. We have investigated the potential for abnormal vitamin D metabolism by giving a single oral dose of 25-hydroxyvitamin D (25OHD) in 10 lymphoma patients (8 Hodgkin's and 2 T-cell) and 7 controls. Serum 25OHD increased similarly in both groups (peak concentrations, 114.1 +/- 9.5 vs. 123.9 +/- 9.6 nmol/L). In controls, serum calcium and PTH did not change after treatment [calcium, 2.31 +/- 0.02 and 2.33 +/- 0.02 mmol/L (mean +/- SEM); PTH, 21.6 +/- 4.0 and 25.4 +/- 4.3 ng/L] 1,25-(OH)2D increased within the normal range from [median (range)] 81 (48-125) to 117 (91-156) pmol/L. In lymphoma patients, serum calcium increased from 2.29 +/- 0.04 to 2.40 +/- 0.06 mmol/L (P = 0.03), PTH decreased from 12.9 +/- 2.6 to 8.0 +/- 1.9 ng/L (P = 0.06), and one patient became hypercalcemic (2.92 mmol/L). Serum 1,25-(OH)2D became supranormal in 6 lymphoma patients; the group median rose from 74.5 (46-180) to 151 (120-487) pmol/L; this peak response differed from that in the controls (P = 0.019). Lymph node and spleen cells from a patient with T-cell lymphoma synthesized [3H]1,25-(OH)2D3 from [3H] 25OHD3 in vitro. The data suggest that abnormal production of 1,25-(OH)2D in lymphoma may be more common than previously recognized given an adequate supply of precursor 25OHD and provide further evidence for the extrarenal synthesis of 1,25-(OH)2D in this condition.

Ultraviolet radiation is a hypothesised risk factor for non-Hodgkin lymphoma (NHL) but no epidemiological study has examined this association using direct measures of sun exposure in individuals. Adults aged 20-74 years living in NSW and ACT, Australia, were the study population. Cases (704 of 829 invited to take part, 85%) were diagnosed January 2000 to August 2001. Controls (694 of 1,136 invited to take part, 61%) were randomly selected from state electoral rolls and frequency-matched to cases by age, sex and state of residence. A self-administered questionnaire and telephone interview measured outdoor hours on working and nonworking days and vacations at 10, 20, 30, 40, 50 and 60 years of age. Logistic regression models of NHL and sun exposure contained the 3 matching variables, ethnicity and sun sensitivity measures as covariates. Contrary to expectations, risk of NHL fell with increasing reported sun exposure hours. Relative to 1.0 for the lowest quarter of total sun exposure hours, the odds ratios (ORs) for successively higher quarters were 0.72 (95% CI 0.53-0.98), 0.66 (0.48-0.91) and 0.65 (0.46-0.91) (p(trend)=0.01). The association of sun exposure on nonworking days with NHL was stronger; OR for highest quarter 0.47 (0.34-0.66) (p(trend)=0.0001). Risk also fell with sun exposure on vacations; OR for highest quarter 0.60 (0.43-0.85) (p(trend)=0.003). These associations appeared strongest in women and in childhood. There was little evident trend in risk with exposure on working day. Our results provide strong statistical evidence for an inverse association between sun exposure and NHL. Increasing evidence that vitamin D may protect against cancer makes UV-mediated synthesis of vitamin D a plausible mechanism whereby sun exposure might protect against NHL.

Experimental studies show that vitamin D derivatives are potent anticarcinogenic factors. Epidemiological observations support this, and vitamin D sufficiency has been hypothesised to be an important risk-reducing factor in several forms of cancer. Vitamin D level exhibits seasonal variations. In the present work, we have investigated the effect of the season of diagnosis on the risk of death among Hodgkin's lymphoma patients diagnosed in Norway between 1964 and 2000. Risk estimates were calculated as relative risk (RR), with 95% confidence intervals (95% CI), using Cox regression model. Epidemiological data for this period indicate that season of diagnosis is a strong prognostic factor for Hodgkin's lymphoma, with approximately 20% lower case fatality for patients diagnosed during autumn vs winter diagnosis (RR = 0.783, 95% CI,-0.62 to 0.99; P = 0.041). Notably, the improved autumnal survival rate was higher than 60% (RR = 0.364, 95% CI, -0.15 to 0.87; P = 0.025) for patients younger than 30 years. This finding may be related to higher endogenous levels of vitamin D in autumn, with a favourable influence on the conventional therapy.

Apperly [1941. The relation of solar radiation to cancer mortality in North America. Cancer Research 1, 191-195] first proposed that increased mortality from cancer in the north than in the south of the USA might be due to the south to north decrease in ambient solar radiation. This inverse association between ambient solar radiation and cancer mortality has been subsequently reported for cancers of the colon, breast, ovary and prostate. While the evidence that sunlight might be related to lower incidence or more favourable outcomes from cancer came initially from ecological studies, case-control and cohort studies have now shown a similar association of sun exposure with risks of colon, breast and prostate cancers in individuals, and other studies in individuals have found that serum and dietary vitamin D levels are associated with reduced risks of colorectal cancer and, less certainly, prostate cancer. Studies in individuals have recently also suggested an effect of sun exposure to reduce risk of non-Hodgkin lymphoma and to increase survival after a diagnosis of melanoma. Data on variation in survival from cancer by season of diagnosis suggest that sun exposure may also improve outcome from cancers of the breast, colon and prostate and Hodgkin lymphoma.

Hypercalcemia is a frequent complication in chronic hemodialysis (CHD) patients. A rare cause of this condition is sarcoidosis, and has only been reported 6 times in CHD. Herein, we report on 3 cases of sarcoidosis-related hypercalcemia in CHD patients: an overt case, a probable case, and a recurrence of pre-dialysis sarcoidosis. Hypercalcemia is a frequent complication in chronic hemodialysis patients: it is often related to uncontrollable secondary hyperparathyroidism or to the inappropriate use of calcium phosphate binders, 1alpha-hydroxylated vitamin D metabolites, high dialysate calcium concentrations, or to aluminium-related bone disease [Uach and Bover 1996]. However, other rare causes should also be considered, such as multiple myeloma, non-Hodgkin lymphoma [Uach and Bover 1996], vitamin A intoxication [Fishbane et al. 1995], or granulomatous diseases such as sarcoidosis. The latter has only been described in a total of 6 hemodialysis patient reports [Barbour et al. 1981, Barnard et al. 2002, Herrero et al. 1998, Kalantar-Zadeh et al. 1994, Kuwae et al. 2003, Naito et al. 1999]. In the present paper, we report on 3 cases of sarcoidosis-related hypercalcemia in chronic hemodialysis patients with 3 different patterns, i.e. overt sarcoidosis, probable sarcoidosis, and recurrence of pre-dialysis sarcoidosis.

This is a rare case report of Hashimoto's thyroiditis in a patient with MALT thyroid lymphomas. The patient presented with an enlarged neck mass over the past 10 years and had rapidly enlarged neck mass with compressive symptoms for about 2 months. Examination by an endocrinologist found that the size of the thyroid gland was 120 gm with firm consistency and with no tenderness. She had clinical hypothyroidism and no abnormality of neither lymphadenopathy nor any masses. She was diagnosed with Hashimoto's thyroiditis because her thyroids function lest showed primary hypothyroidism [(FT4 = 0.76 ng/dl (0.93-1.71), FT3 = 1.76 pg/ml (1.8-4.6), TSH = 8.24 mIU/L (0.27-4.21)] with antimicrosomal antibody positive titers (> 1:409,600): Diagnosis of primary thyroid lymphoma was diagnosed by FNA and total thyroidectomy was performed. About 1 day after total thyroidectomy, she developed clinical hypocalcemia and the laboratory showed that calcium was = 6.2 ng/dl (8.5-10.1), phosphorus = 6.4 mg/dl (2.5-4.9). After 10% calcium gluconate replacement, her hypocalcemic symptoms didn't appear and she received oral replacement of calcium carbonate and vitamin D before discharge. During OPD follow up, her pathological report from Maha Chakri Sirinthorn Medical Center was a diagnosis of Non Hodgkin's lymphoma, low grade and the latter 1 week immunohistochemically staining of tumor markers indicated B-cell type (CD20) with MALT (AE1/AE3) lymphoma. Staging of the disease was stage IE and she received one course of CHOP (Cyclophosphamide, doxorubicin, vincristin and prednisolone). After one course of CHOP regimen, she was healthy and the hematologist ordered two courses of CHOP and external radiation.

There is increasing evidence that vitamin D reduces the risk of many types of cancer. Geographic variations in cancer mortality rates in Spain are apparently linked to variations in solar ultraviolet (UV) irradiances and other factors. Cancer mortality rates for 48 continental Spanish provinces for 1978-1992 were used in linear regression analyses with respect to mortality rates for latitude (an index of solar UVB levels), skin cancer (an index of high cumulative UVB irradiance), melanoma (an index related to solar UV irradiance and several other factors) and lung cancer (an index of cumulative effects of smoking). The 9 cancers with mortality rates significantly correlated with latitude for 1 or both sexes were brain, gastric, melanoma, nonmelanoma skin cancer (NMSC), non-Hodgkin's lymphoma (NHL), pancreatic, pleural, rectal and thyroid cancer. Inverse correlations with latitude were found for laryngeal, lung and uterine corpus cancer. The 17 cancers inversely correlated with NMSC are bladder, brain, breast, colon, esophageal, gallbladder, Hodgkin's lymphoma, lung, melanoma, multiple myeloma, NHL, ovarian, pancreatic, pleural, rectal, thyroid and uterine corpus cancer. The 16 correlated with melanoma are bladder, brain, breast, colon, gallbladder, leukemia, lung, multiple myeloma, NHL, ovarian, pancreatic, pleural, prostate, rectal, renal and uterine corpus cancer. The results for lung cancer were in accordance with the literature. These results provide more support for the UVB/vitamin D/cancer hypothesis and indicate a new way to investigate the role of solar UV irradiance on cancer risk. They also provide more evidence that melanoma and NMSC have different etiologies.
