Liposome-entrapped doxorubicin (Lip-Dox) was evaluated in two phase I clinical trials in patients with hepatic malignancy. Patients with metastases from primary gastric or colonic tumours and patients with hepatoma were eligible. Lip-Dox was extremely well tolerated and acute toxicities such as nausea and vomiting were totally eliminated; no antiemetics were used even at doses of 80 mg/m2. Toxicities such as alopecia and myelosuppression were also ameliorated. There were tumor regressions and reductions in hepatomegaly in patients treated on both the weekly and 21-day studies. The maximum tolerated dose (MTD) in the weekly study was 22.5 mg/m2/week and in the 21-day trial the MTD was 70 mg/m2.

The National Cancer Institute of Canada (NCIC) Clinical Trials Group conducted a phase II study of weekly oral menogaril as first-line therapy in 51 patients with incurable, metastatic or locally advanced breast cancer. While no prior chemotherapy for metastatic disease was permitted, prior adjuvant chemotherapy was allowed provided that no anthracycline or anthracene had been given. Forty-eight patients were evaluable for response. Two patients (4%) achieved complete remissions, 9 patients (19%) achieved partial remissions, 26 patients (54%) were stable and 11 patients (23%) failed. At the initial menogaril dose of 275 mg/m2 per week, 13 of 14 patients required a dose reduction and/or a treatment delay of one or more weeks. Therefore, the menogaril dose was reduced to 225 mg/m2 per week for the last 37 patients. At that those, 20 of 37 patients developed grade 3 or 4 granulocytopenia and 22 required dosage delays. At the initial starting dose, the average dose intensity actually delivered was 169 mg/m2 per week. At 225 mg/m2 the average dose intensity actually delivered was 197 mg/m2 per week. Toxic effects included mild to moderate nausea and vomiting, diarrhea, hair loss and occasional hyperpigmentation. In summary, menogaril is an anthracycline derivative that has modest activity when administered orally to minimally pretreated patients with breast cancer.

Systemic treatment with tumor necrosis factor (TNF) is associated with side-effects, limiting its clinical use in the treatment of malignancies. To investigate the feasibility of other routes of administration experimental and clinical studies were started to establish the toxicity and antitumor activity of TNF after intratumoral (i.t.) injection. In a rat model for colon adenocarcinoma, tumor fragments, implanted subcutaneously or under the hepatic capsule, were treated with TNF injected i.v. or i.t. A dosage of 40 micrograms/kg was lethal when given i.v., but not i.t. Injection of TNF (40 micrograms/kg) directly into the tumor resulted in inhibition of tumor growth in the subcutaneous as well as subhepatic tumor model. A phase I study was started in patients with advanced malignancies to determine the toxicity of TNF injected into liver metastases. Injection of TNF into liver metastases was accomplished by ultrasonography. A 50 microgram-dose escalating schedule (3 patients/dosage) was chosen, starting at a dose of 100 micrograms TNF/injection. Up to now, 12 patients have been treated, the highest dosage of TNF injected being 250 micrograms. Chills, fever, nausea and vomiting were the main side-effects. No significant changes were found in circulatory, hematologic, renal and liver parameters. In summary, i.t. administration of TNF is associated with antitumor efficacy in experimental models and well-tolerated in man. The antitumor efficacy of TNF i.t. in man awaits evaluation in a phase II study.

Cisplatin has played a major role in the treatment of germ cell tumors. However, it causes renal damage, severe nausea and vomiting. It is also neurotoxic and ototoxic. Carboplatin is an analog of cisplatin which, does not cause renal damage at therapeutic doses. It is not neurotoxic or ototoxic and it produces less gastrointestinal toxicity than cisplatin. We used carboplatin alone as an initial chemotherapy in a 36-year-old man with stage IIB seminoma. Following left radical orchiectomy the patient received 4 courses of carboplatin chemotherapy. After the first course of chemotherapy, tumor markers (LDH, beta-HCG) returned to the normal range. After 4 courses, the size of the retroperitoneal metastases was significantly reduced. The toxicity of 4 courses of carboplatin chemotherapy was generally milder than that of cisplatin-based combination chemotherapies such as PVB or VAB-6. There were no episodes of septicemia, thrombocytopenic bleeding or renal deterioration. The patient did not suffer from alopecia, neuropathy, symptomatic hearing loss, severe nausea or vomiting. Nine months after the completion of carboplatin chemotherapy, the patient remains well and free from disease progression. This case strongly suggests that single agent carboplatin therapy could be an effective and less-toxic treatment for advanced seminoma.

15 patients with therapy-resistant liver metastases were treated in a phase I study with recombinant tumour necrosis factor (rTNF). rTNF was injected into a liver metastasis by ultrasound guidance, using a 50 micrograms escalating dose schedule (3 patients/dosage) ranging from 100 to 350 micrograms per injection. Influenza-like symptoms such as fever, chills, nausea and vomiting were the main clinical side-effects. 2 patients experienced transient hypotension, probably due to concomitant use of morphine. Other toxicities, as reported after systemic use of rTNF, such as decrease in leucocytes and platelet counts, renal or liver toxicity were not observed. No difference was seen in subpopulations of lymphocytes (CD3+, CD4+, CD8+, CD16+ and CD19+) prior to and after rTNF injection. In 8 patients stable disease occurred in rTNF-treated metastases. The maximal dose used by this route of administration is 350 micrograms per injection. Based on these observations we conclude that the toxicity of rTNF injected into liver metastases by sonographic control is transient and mild. The results suggest that intratumoral administration of rTNF might play a role in local tumour control.

Melanoma frequently disseminates to the gastrointestinal tract, being found post-mortem in 60 per cent of patients with disseminated disease, while during life it is diagnosed in only 4 per cent. During the period 1981-87, 835 melanoma patients were referred and 30 developed complaints caused by gastrointestinal metastatic melanoma. Twenty-three patients were treated surgically. The interval between treatment of the primary melanoma and detection of intestinal involvement was a median of 34 months (range 2-87 months). In four patients recurrence in the gut was the first evidence of dissemination. Major complaints were nausea and vomiting, abdominal pain, signs of anaemia, and blood in the stools. Complications were bleeding (ten cases), ileus due to intussusception (five cases), bowel perforation (four cases) and cholecystitis (one case). The metastases, mainly localized in the small bowel, were removed by relatively simple procedures. Symptoms were reduced in 19 patients. Two patients died after operation: one from sepsis due to suture leakage, the other from pneumonia and a cerebrovascular accident. Of the remaining patients, 16 survived a median of 7.5 (range 0.7-32.0) months. Five patients are still alive 72, 72, 70, 7 and 2 months after the metastasectomy, three of whom are tumour-free. The actuarial 5-year survival of all patients is 19 per cent. These results support surgical intervention for patients with complaints and/or complications attributable to gastrointestinal metastatic melanoma.

Patients suffering from malignant disease will probably develop some metabolic abnormality of electrolytes. Hypernatremia is defined as an elevation of serum natrium over 150 mEq/l and caused by decrease of water intake, low level of ADH secretion and impaired response of kidney to ADH. Hyponatremia below 135 mEq/l of serum natrium is caused by SI-DAH, sick cell syndrome and increased loss of natrium from the kidney. On the other hand, hyperkalemia is defined as an elevation of serum kalium over 5.0 mEq/l and caused by acute tumor cell lysis syndrome, adrenal and renal insufficiency. Hypokalemia is caused by kalium loss from kidney and hypersecretion of mineral corticoid. Hypercalcemia is found in the high frequency among patients with malignant disease. Hypercalcemia is defined as an elevation of serum calcium over 11.0 mg/dl, although the most important aspect is the level of ionized calcium. The excess calcium causes defective urinary concentration with polydipsia, nausea and vomiting leading to volume depletion. At serum calcium levels about 13.8 mg/dl, there may be rapid deterioration or renal function, dehydration, coma and cardiac arrhythmias. Hypercalcemia is rarely the first manifestation of cancer. There are three principle pathogenic causes of malignant hypercalcemia, 1) hypercalcemia is a feature of several hematological cancers, including Burkitt's lymphoma, T cell leukemia, but most commonly with myeloma. The hypercalcemia in these myeloma patients is due to the secretion of an osteoclast activator, a lymphokine by the myeloma cells. 2) all patients with bony metastases have biochemical evidence of increased bone resorption. However, not all patients with bony metastases develop hypercalcemia. Probably the hypercalcemia is due partially to increased renal tubular reabsorption of calcium, mediated by a humoral factor, with activity similar to that of parathormone. 3) hypercalcemia in the patients without bony metastases is due to increased bone resorption caused by the ectopic secretion by the tumor. Mildly symptomatic patients will benefit from modest salt loading. They are dehydrated and replacement of the extracellular fluid is the first line of treatment. This may require 4-10 l normal saline/24 h. In addition, frusemide will increase calcium excretion. Calcitonin may be given subcutaneously or intravenously to refuse the mobilisation of calcium from bone. Glucocorticoids are unhelpful, but will prolong the effect of calcitonin. A diphosphonate is also useful.

Gallbladder cancer afflicts predominantly women, the elderly, and persons with gallstones. Despite its producing symptoms of abdominal pain, nausea and vomiting, weight loss, jaundice, and anorexia, this disease remains difficult to detect. Even with contemporary imaging techniques, most gallbladder cancers escape diagnosis until the time of laparotomy. The aggressive character of this malignancy permits an overall 5-year survival rate of 3-5%. Although cures occur, the majority of operations performed for gallbladder cancer are for palliation. The objects of palliation include relief of pain, relief of jaundice, relief of intestinal obstruction, and the restoration of normal food intake. Resection of the tumor should be performed whenever possible; however, extensive operations including large liver resections and pancreaticoduodenectomy should be avoided in the presence of distant metastases. In the presence of large unresectable hilar masses, internal biliary bypass may relieve jaundice. Biliary-enteric anastomosis using the segment III duct exposed via the umbilical fissure may offer satisfactory relief of jaundice in selected cases.

One course of chemotherapy containing cisplatin and bleomycin as a neoadjuvant treatment was given to 26 consecutive patients with previously untreated stage IB (bulky disease)-III cervical carcinoma and followed by radical surgery. After chemotherapy responses were detected in 23 patients (5 complete and 18 partial; overall, 88%) and permitted radical surgery in 21 cases (81%). Surgery consisted of type III-IV radical hysterectomy plus systematic para-aortic and pelvic lymphadenectomy. At histologic examination, complete responses were found in 5 (19%) and partial responses in 16 (62%) cases. The average number of lymph nodes removed was 61 (range, 38-118). A lower than expected incidence of lymph node metastases was detected (2/21, 9.5%). The chemotherapy-induced toxicity was mainly represented by nausea and vomiting. Chemotherapy did not seem to complicate surgery in these circumstances, even though moderate-degree postoperative complications occurred in 48% of cases. Eighteen months median follow-up time (range, 11-23) from hystological diagnosis has been reached in the operated patients, and no recurrences have been detected so far.

In two pilot studies, 55 patients with symptomatic metastases from malignant melanoma were treated with irradiation and concurrent cisplatin. In the first group, cisplatin was given as a continuous intravenous infusion of 20 mg/m2 per day on days 1-5 and 22-26, with irradiation on days 2, 5, 9, 16, 23 and 26. The second group received 20 mg cisplatin over 24 h commencing 1 h before each fraction of irradiation on days 1, 4, 8, 11, 15 and 18. The first series of 28 patients had 30 lesions treated. Nine (30%) of these lesions responded completely and 10 (33%) achieved partial response for an overall response rate of 63% (95% confidence interval 44-80%). Survival was not evaluated in this group. The second group was comprised of 27 patients, with one irradiated lesion each. 1 patient achieved a complete response and 13 (48%) a partial response for an overall response rate of 52% (32-71%). Median survival was 21 weeks (16-31 weeks). Treatment was well tolerated with nausea and vomiting being the most common toxicity. Synchronous cisplatin infusion with radiotherapy achieves high response rates in metastatic melanoma. Whether it is superior to radiotherapy alone will require evaluation in a randomised trial.
