A Phase I dose escalation and pharmacokinetic study of the alkylating cytotoxic agent treosulfan was conducted to evaluate the maximum tolerated dose and the dose-limiting toxicities in patients with advanced malignancies rescued by autologous peripheral blood stem cell transplantation. Twenty-two patients (15 ovarian and 7 other carcinomas/lymphomas) with a median age of 48 years were treated with 28 high-dose courses. Treosulfan was infused over 2 h at escalating doses from 20 to 56 g/m2, and pharmacokinetic parameters were analyzed. At 56 g/m2, three of six patients experienced dose-limiting toxicities: diarrhea grade III/IV in three patients; mucositis/stomatitis grade III in one patient; toxic epidermal necrolysis in one patient; and grade III acidosis in one patient. Other low-grade side effects, including erythema, pain, fatigue, and nausea/vomiting, were recorded. Two patients died within 4 weeks after treatment because of rapid tumor progression and fungal infection, respectively. Plasma half-life, distribution volume, and renal elimination of treosulfan were independent of dose, whereas the increase in area under the curve was linear up to 56 g/m2 treosulfan. The maximum tolerated dose of high-dose treosulfan is 47 g/m2. A split-dose or continuous infusion regimen is recommended for future high-dose trials. In consideration of antineoplastic activity and limited organ toxicity, inclusion of high-dose treosulfan in combination protocols with autologous peripheral blood stem cell transplantation seems worthwhile.

Hydroxyurea is an antimetabolite agent used in the treatment of myeloproliferative disorders and sickle cell anaemia. Although hydroxyurea is relatively well tolerated, adverse effects often involve skin and mucous membrane during long-term therapy. A group of 510 patients affected by chronic myeloid leukaemia from 1977 to 1998 has been considered. Only 158 patients were treated with hydroxyurea and fulfilled inclusion/exclusion criteria of this study. A spectrum of severe cutaneous and mucosal changes (inflammatory and neoplastic) was seen in about 13% of patients (21 patients out of 158) and was studied in detail. Cutaneous and mucosal atrophy were observed in all 21 patients. Skin atrophy was often characterized by numerous telangiectases, especially on legs and on sun-exposed sites (16/21). Cutaneous, mucosal and nail hyperpigmentation was evident, albeit with variable extent, in 10 of the 21 patients. Severe stomatitis and glossitis with flattening of papillae were another common finding. Five patients, who received a particularly long treatment with hydroxyurea, developed squamous-cell neoplasms on sun-exposed sites (both squamous-cell carcinomas and keratoacanthomas). Acral changes were characteristic and constant, including acral erythema (21/21), dermatomyositis-like changes on the dorsa of hands (7/21), ulcers localized on acral areas of legs, on genitalia and oral mucosae (20/21). The frequency and the variety of these muco-cutaneous changes are reported and the mechanisms by which hydroxyurea may induce this muco-cutaneous syndrome-like group of changes, are proposed.

Glucagonoma syndrome is a paraneoplastic phenomenon characterized by an islet alpha-cell pancreatic tumor, necrolytic migratory erythema, diabetes mellitus, weight loss, anemia, stomatitis, thromboembolism, and gastrointestinal and neuropsychiatric disturbances. These clinical findings in association with hyperglucagonemia and demonstrable pancreatic tumor establish the diagnosis. Glucagon itself is responsible for most of the observed signs and symptoms, and its induction of hypoaminoacidemia is thought to lead to necrolytic migratory erythema. Liver disease and fatty acid and zinc deficiency states may also contribute to the pathogenesis of the eruption in some cases. Most patients are diagnosed too late in the clinical course for cure, but successful palliation of symptomatology can usually be achieved with surgical and medical intervention. This paper reviews the glucagonoma syndrome, paying particular attention to its cutaneous features, and provides new perspectives in our current understanding of this phenomenon.

Twenty of 25 horses in a well-managed Missouri boarding stable were diagnosed with gingivitis/stomatitis. Gross examination of the affected horses revealed varying degrees of gingivitis ranging from mild periodontal swelling to marked swelling and erythema with ulceration and hemorrhage. Fine hair-like material was embedded within the intensely affected areas. Gingival biopsies from 4 affected horses contained pyogranulomatous inflammation with, in some cases, numerous eosinophils and several grass awns in cross and longitudinal section. Numerous foxtail seed heads were identified in hay samples. Examination of the records revealed that all of the affected horses had been fed the suspect hay, with the exception of 1 horse. Although not deliberately fed the suspect hay, this horse did have access to the hay when turned out into the exercise paddock. The lesions resolved following a change in hay source.

Glucagonomas are rare tumors. They are predominantly located in the body or tail of the pancreas and display a constellation of signs and symptoms referred to as glucagonoma syndrome. The term necrolytic migratory erythema is used to characterize the distinctive rash associated with this syndrome. This report describes a classic presentation consisting of dermatitis, glossitis, stomatitis, angular cheilitis, anemia, and weight loss that was associated with the finding of a pancreatic mass and a markedly elevated plasma glucagon level. After pancreatic resection, the patient had complete resolution of the rash and normalization of plasma glucagon.

This study used a prospectively managed clinical database in order to identify 1470 patients with gastrointestinal cancers receiving protracted venous infusion (PVI) fluorouracil (5FU). It aimed to determine the time course of toxicity due to PVI 5FU and to analyse factors predicting toxicity. The initial development of stomatitis occurred more rapidly than diarrhoea or palmar plantar erythema (PPE). The percentage of patients with National Cancer Institute Common Toxicity Criteria (CTC) grade 2 or worse PPE peaked at 9% between weeks 8 and 17, whereas this peak occurred earlier for stomatitis and diarrhoea. The development of CTC grade 1 toxicity in the first 28 days after commencement of chemotherapy was classified as early grade 1 toxicity. Multivariate Cox regression analysis showed that female sex, better performance status, elevated bilirubin, early grade 1 PPE and early grade 1 diarrhoea were independent prognostic factors for the development of CTC grade 2 or worse PPE (P<0.01). Female sex, increased age, elevated alanine transaminase and urea and early grade 1 PPE were significant independent prognostic factors for the development of CTC grade 2 or worse stomatitis (P<0.01). Early CTC grade 1 diarrhoea predicted CTC grade 2 or worse diarrhoea (P<0.01). Older, female patients with good performance status and impaired liver and renal function who develop early grade 1 PPE alone or in combination with diarrhoea are at highest risk of subsequently developing grade 2 or worse PPE or stomatitis during treatment with PVI 5FU. Reduction of infused 5FU dose should be considered for these patients. Such an approach could both reduce severe toxicity owing to chemotherapy and minimise treatment delays, and should be evaluated prospectively.

Pellagra is a nutritional wasting disease attributable to a combined deficiency of tryptophan and niacin (nicotinic acid). It is characterized clinically by four classic symptoms often referred to as the four Ds: diarrhea, dermatitis, dementia, and death. Prior to the development of these symptoms, other nonspecific symptoms insidiously manifest and mostly affect the dermatological, neuropsychiatric, and gastrointestinal systems. A review of the literature reveals several case reports describing pellagra in patients with anorexia nervosa. The most common features of pellagra in patients with anorexia nervosa are cutaneous manifestations such as erythema on sun-exposed areas, glossitis, and stomatitis. Health care providers might consider a trial of 150-500 mg niacin if anorexic patients exhibit these cutaneous findings. Pellagra can be diagnosed if cutaneous symptoms resolve within 24-48 hours after oral niacin administration. To further corroborate a diagnosis of pellagra in anorexic patients, specific 24-hour urine tests for niacin metabolites and 5-hydroxy-indole-acetic acid could be run prior to treatment with niacin being instituted. Other factors, such as mycotoxins, excessive dietary leucine intake (although not in anorexia), estrogens and progestogens, carcinoid syndrome, and various medications, might also lead to the development of pellagra. Although pellagra appears to be a rare, yet possible secondary complication of anorexia nervosa, it should be considered in the work-up of patients who exhibit cutaneous manifestations subsequent to sunlight exposure.

We studied the effects of 0.25% indomethacin (IM) spray as an in-hospital preparation on the pain of stomatitis after hematopoietic stem cell transplantation in 9 patients with various types of leukemia by measuring the change in pain and the decrease in morphine dose. Stomatitis above grade 2 (painful erythema, edema, or ulcers but can eat or swallow) appeared in all patients as white blood cell (WBC) counts declined after transplantation, and clockwise hysteresis was observed between WBC counts and the grade of stomatitis. When the patients used IM spray for the pain of stomatitis and were judged the grade of pain using a face scale of five grades (0-4) before and after the use of this spray, the mean grades of pain at the maximal pain during the appearance of stomatitis declined from 3.4 to 1.8 (n = 5). Furthermore, the concurrent intravenous dose of morphine markedly decreased during IM spray use. There was no complaint concerning the taste and convenience of IM spray by patients. The risk of systemic adverse effects was considered relatively low based on the small amounts of IM applied to the mouth mucosa. In conclusion, it is suggested that IM spray is effective for the relief of stomatitis pain in patients who have undergone hematopoietic stem cell transplantation and is a useful preparation for immediate self-medication upon the appearance of stomatitis pain. We considered that the application of IM spray will contribute to the improvement of patient quality of life.

A rare case of Stevens-Johnson syndrome (SJS) due to peplomycin in a 48-year-old man is described. The patient had squamous cell carcinoma on the scalp and underwent preoperative neoadjuvant chemotherapy with peplomycin. On the fifth day of the chemotherapy, he developed a fever and multiple dusky violaceous erythematous areas and pustules on his trunk, thighs, and palms. Erosive erythema and erosions also developed on his soles, scrotum, and oral mucosa. A biopsy specimen taken from the eruption on the thigh revealed marked liquefaction degeneration of the basal layer of the epidermis. Laboratory examinations demonstrated aggravation of liver function. Additionally, the patient developed conjunctivitis and corneal erosions. Although he had some subcorneal pustules, we diagnosed the case as an unusual form of SJS because of severe mucous membrane involvement. Oral prednisolone was administered, and the symptoms subsided. Then the patient underwent wide local excision. One month after surgery, we performed patch tests and a lymphocyte stimulation test with negative results. Then we re-administered peplomycin starting with 1/20 of a daily dose and gradually increasing the dose each day. After administration of the regular daily dose, the patient had a relapse of fever, eruptions, stomatitis, corneal erosions, and liver dysfunction. Therefore, a definite diagnosis of drug eruption due to peplomycin was made.

The purpose of the study was to establish the optimal dose of capecitabine (X) to be used within a multicentre, randomised study evaluating the potential roles of oxaliplatin (O) and X in chemonaive patients (pts) with advanced oesophagogastric cancer. Two by two design was used, and pts were randomised to one of four regimens and stratified for extent of disease, performance status (PS) and centre. The treatment regimens are epirubicin, cisplatin, 5-fluorouracil (ECF), EOF, ECX or EOX. Doses: E 50 mg m(-2), C 60 mg m(-2) and O 130 mg m(-2) i.v. 3 weekly; F 200 mg m(-2) day(-1) i.v. and X 500 mg m(-2) b.i.d.(-1) (escalated to 625 mg m(-2) b.i.d.(-1) after results of first interim analysis) p.o., continuously. First interim analysis was performed when 80 pts had been randomised. Dose-limiting fluoropyrimidine toxicities were stomatitis, palmar plantar erythema (PPE) and diarrhoea; 5.1% of X-treated pts experienced grade 3/4 toxicity. Protocol planned dose escalation of X to 625 mg m(-2) b.i.d.(-1) was instituted and a second interim analysis has been performed; results are presented in this paper. A total of 204 pts were randomised at the time of the protocol planned 2nd interim analysis. Grade 3/4 fluoropyrimidine-related toxicity was seen in 13.7% pts receiving F, 8.4% pts receiving X 500 mg m(-2) b.i.d.(-1) and 14.7% pts receiving X 625 mg m(-2) b.i.d.(-1). Combined complete and partial response rates were ECF 31% (95% CI 18.7-46.3), EOF 39% (95% CI 25.9-53.1), ECX 35% (95% CI 21.4-50.3), EOX 48% (95% CI 33.3-62.8). Grade 3/4 fluoropyrimidine toxicity affected 14.7% of pts treated with X 625 mg m(-2) b.i.d.(-1), which is similar to that observed with F, confirming this to be the optimal dose. The replacement of C by O and F by X does not appear to impair efficacy. The trial continues to total accrual of 1000 pts.
