Ninety-eight patients with small cell carcinoma of the bronchus (SCCB) were treated with a combination of cyclophosphamide, methotrexate with calcium leucovorin rescue, and lomustine (CCNU). VP-16-213 was given on relapse. Response rate and survival were analyzed according to extent of tumor, presence of the syndrome of inappropriate antidiuretic hormone production (SIADH), and, in 38 patients, size of intrathoracic tumor as measured by computerized tomographic (CT) scanning. The median survival of the entire group was 34.6 weeks. In patients with limited disease the median survival was 46 weeks compared to 29 weeks for those with extensive disease. This difference in survival between patients with limited and extensive disease was most marked in those showing a partial response (median survival, 45.9 and 28 weeks, respectively). Patients with ectopic antidiuretic hormone production had a poor prognosis even if they had achieved a complete response. Only one partial response to VP-16-213 occurred. There was a strong correlation between initial intrathoracic tumor size as assessed by total cross-sectional area on CT scan and response and survival. When the total area exceeded 30 cm2 there were no complete responders, but there were complete responses in eight of 21 patients when the area was less than 30 cm2. The relationship between intrathoracic tumor size and response rate was present when analyzed according to disease extent, age, sex, and performance status. A clear relationship between total tumor area and survival was also found. When SCCB is treated with chemotherapy alone, the prognosis is better for those patients who present with limited disease, without SIADH, and with small intrathoracic tumor. In this group it is possible that further intensification of therapy may result in prolonged survival.

A 69-year-old female was admitted to the hospital because of fever, hyponatremia and anemia. Laboratory data showed hemoglobin 8.6 g/dl, indirect bilirubin 1.9 mg/dl and Na 122 mEq/l. Urine osmolality was elevated and urinary excretion of sodium was increased. Furthermore, antidiuretic hormone (ADH) level was elevated. Renal function and hormonal data were within normal limit. Therefore, she was diagnosed as having syndrome of inappropriate secretion of antidiuretic hormone (SIADH). On the other hand, bone marrow aspiration showed hemophagocytosis and the diagnosis of hemophagocytic syndrome (HPS) was also made. High dose prednisolone and pulse therapy of cyclophosphamide were administered, nevertheless high grade fever persisted. Fever alleviation was acquired by Etoposide. But she died of pneumonia. An autopsy revealed hemophagocytosis in bone marrow, lymphnodes and spleen, but malignant tumor was not detected. And hypophysis was intact. The pathogenesis of SIADH in this case was not clarified. This report is seemed to be the first case of HPS associated with SIADH.

i.p. administration of cytotoxic drugs for the treatment of regionally confined cancers results in a greater total drug exposure [area under the concentration x time curve (AUC)] for the peritoneal fluid and regional lymphatics than for plasma. We sought to augment the relative advantage of i.p. administration further through modulation of peritoneal clearance by reduction in splanchnic blood flow. Pigs were treated with 5-fluorouracil, etoposide (VP-16), and carboplatin (CBDCA) alone by the i.p. route or with the same drugs in combination with i.v. lypressin, a synthetic vasopressin analogue, which reduces splanchnic blood flow. Drug concentrations in peritoneal fluid, plasma, and thoracic duct lymph were monitored over the ensuing 6 h. The pharmacokinetics of 5-fluorouracil were not altered by vasopressin; however, vasopressin increased the peritoneal fluid:plasma AUC ratio for CBDCA from 30.6 +/- 5.6 to 70. 6 +/- 7.4 (P < 0.01) and increased the lymph:plasma AUC ratio from 1.1 +/- 0.4 to 2.6 +/- 0.22 (P < 0.05). In the case of VP-16, vasopressin increased the peritoneal fluid:plasma AUC ratio from 129 +/- 35 to 350 +/- 76 (P < 0.05) and the lymph:plasma AUC ratio from 2.1 +/- 0.6 to 10.6 +/- 3.5 (P < 0.05). Concurrent i.v. administration of vasopressin can increase the pharmacokinetic advantage of the i.p. route of administration of CBDCA and VP-16 markedly in the pig model. These data suggest that the strategy of concurrent i.p. administration of CBDCA or VP-16 plus an agent that reduces splanchnic blood flow may increase the dose intensity in the abdominal cavity and intraabdominal lymphatic tissue substantially without increasing systemic toxicity.

A 73-year-old man with progressive prostate cancer visited our hospital after prostate biopsy performed at another hospital. His serum PSA level was 29.02 ng/ml. CT revealed invasion of the bladder, bilateral ureters, and rectum. Otherwise, there was no evidence of metastasis. Pathological findings showed a poorly differentiated adenocarcinoma (Gleason score 4+5) and small cell carcinoma component. Two months after administering combined androgen blockade therapy, he was admitted due to severe hyponatremia caused by the inappropriate secretion of antidiuretic hormone. Furthermore, CT revealed right ureter metastasis, although the PSA levels remained low. Therefore, the patient was put on fluid restriction and sodium administration. After the patient recovered from hyponatremia, chemotherapy, including VP-16 and CDDP, was initiated. However, CT after two chemotherapy cycles revealed disease progression, with multiple bone metastases. Second-line chemotherapy, including CPT-11 and CDDP, was less effective, and the patient died 9 months after the diagnosis.
