We report the case of a 14-year-old boy with myelodysplastic syndrome (MDS/RAEB) which developed following Fanconi anemia. The patient received BMT from an HLA-identical sister. Based on the in vitro CY-sensitivity test, 100 mg/kg of CY was administered for conditioning combined with 6 Gy TBI. Mucosal symptoms such as stomatitis, diarrhea and hematuria were severe, but manageable, and engraftment was successful. The patient has maintained normal trilineage hematopoiesis with > 90% Karnofsky score for 30 months with disappearance of a clonal chromosomal abnormality (47,XY, +i(lq)) which was detected before BMT.

The oral manifestations of glossitis, stomatitis and mucosal ulceration in vitamin B12 deficiency have long been recognised. These oral changes may occur in the absence of symptomatic anaemia or of macrocytosis. The aim of this paper is to describe a retrospective study of the wide range of oral signs and symptoms reported by 14 patients found to have a previously undiagnosed vitamin B12 deficiency. None of the patients described in this study had generalised symptoms sufficiently advanced to arouse suspicions of vitamin B12 deficiency. The essential criteria for the diagnosis of pernicious anaemia are also discussed.

Induction chemotherapy followed by radiation has been extensively studied in an effort to improve local control and possibly overall survival of patients with locally advanced head and neck cancer. From June 1989 until May 1991, 39 patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with 3 cycles of induction chemotherapy, consisting of cisplatin (100 mg/m2 d 1) and fluorouracil (1000 mg/m2 d 2-6) followed by radiation potentiated by weekly administration of carboplatin (60 mg/m2). Surgery was performed in selected patients with residual disease after the combined modality approach. Four cycles of adjuvant chemotherapy with carboplatin (325 mg/m2) and bleomycin (15 u) were administered in those patients who demonstrated a partial response after locoregional treatment. There were 36 men and 3 women with a median age of 56 (range 39-74) years and Karnofsky performance status of 70 (range 60-100). The primary site of the tumor was nasopharynx (8), oropharynx (8), hypopharynx (3), oral cavity (4), larynx (13), paranasal sinus (2), and salivary glands (1). Thirty-two (82%) patients presented with stage IV disease. After the completion of induction chemotherapy, 14 (36%, 95% CI 21-53%) patients achieved a complete response (CR). This CR rate was increased to 56% (95% CI, 42-74%) after locoregional treatment. Main toxicities included nausea/vomiting (56%), leukopenia (40%), anemia (30%), thrombocytopenia (10%), stomatitis (28%), diarrhea (17%), and alopecia (12%). Median relapse-free survival was 18 (1-50) months, median time to progression was 13 (0.3-58.5) months, and median survival 19 (0.3-59) months. Induction chemotherapy with cisplatin and fluorouracil followed by radiation potentiated with carboplatin is feasible. However, this combined modality approach, as applied in the present study, does not appear to yield superior results than those reported with chemotherapy followed by radiation alone.

Etoposide, leucovorin and 5-fluorouracil (ELF) chemotherapy has been reported to be less toxic yet effective (response rates of 50%) in patients with advanced gastric cancer. A phase II study of ELF in 25 patients (11 males, 14 females, median age 53 years) with advanced adenocarcinoma of the stomach is reported. Patients received outpatient intravenous etoposide 120mg/m2 over 2 hours, folinic acid 300 mg/m2 over 2 hours, 5-fluorouracil 500 mg/m2 boluses daily for 3 days every 21 days. Of 17 measurable patients, there was one complete response (CR), 4 partial responses (PR) for a total response rate of 29.4%. Non-hematologic toxicity was modest (grade 0 vomiting 11/21, stomatitis 16/21, diarrhea 17/21). Grade 3/4 neutropenia was seen in 14/23, thrombocytopenia in 2/23, anemia in 5/23 patients. Median progression-free and overall survival was 4.1 and 7.1 months, respectively. In conclusion, ELF chemotherapy shows only modest activity in patients with advanced gastric cancer and is associated with severe hematologic toxicity.

A comparative, randomized trial was conducted to determine the efficacy of oral UFT (Tegafur and Uracil) versus 5-fluorouracil (5-FU) in combination with cyclophosphamide and doxorubicin in patients with metastatic breast cancer. Of 62 evaluable patients, 31 received UFT (350 mg/m2/day orally x 14 days), doxorubicin (50 mg/m2 intravenously [I.V.] day 1) and cyclophosphamide (500 mg/m2 I.V. day 1). The other 31 patients received 5-FU (500 mg/m2 I.V. days 1 and 8), doxorubicin (50 mg/m2 I.V. day 1), and cyclophosphamide (500 mg/m2 I.V. day 1). Regimens were repeated for a total of six cycles. The two groups were comparable in terms of age, gender, performance status, menopausal status, and number and sites of metastases. No statistical difference in overall response rates was seen (UFT arm, 48.4% vs. 5-FU arm, 35 %; p = 0.30). Median response duration was 16 weeks (range, 4-30) for both arms. The toxicity profile (alopecia, anemia, leukopenia, thrombocytopenia, diarrhea) was similar in both groups and both regimens were well tolerated. Anemia and stomatitis were significantly more common in the 5-FU arm (p = 0.02). Thus, oral UFT has response rates and duration of response that are comparable to 5-FU in a combination regimen for advanced breast cancer.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) appears to be one of the most active drugs in the treatment of advanced head and neck cancer. The maximum tolerated dose of paclitaxel in combination with carboplatin is currently being evaluated in phase I/II studies. We designed a phase II study to evaluate the activity and acute and cumulative toxicity of this combination in patients with recurrent or metastatic cancer of the head and neck. Chemotherapy consisted of paclitaxel 200 mg/m2, given as a 3-hour infusion, and carboplatin dosed to an area under the concentration-time curve of 7 mg x min/mL, administered every 28 days. Granulocyte colony-stimulating factor (5 microg/kg) also was given on days 2 to 12 of each cycle. At the time of this report, 41 patients had entered this study. Primary sites included the nasopharynx (10 patients), larynx (18), oral cavity (three), oropharynx (six), hypopharynx (three), and unknown (one). Among 25 evaluable patients with non-nasopharyngeal cancer, there were two complete responses and three partial responses, for an overall response rate of 20% (95% confidence interval, 4% to 36%). Among eight evaluable patients with nasopharyngeal cancer, four achieved a complete response and two a partial response. Grade 3 to 4 toxicities included anemia (2.5%), leukopenia (7.5%), thrombocytopenia (5%), vomiting (5%), stomatitis (2.5%), and infection (5%). These preliminary data indicate that the combination of paclitaxel and carboplatin is active against advanced head and neck cancer, particularly when used in the treatment of nasopharyngeal cancer.

Doxorubicin is an antineoplastic drug which has in vitro and in vivo activity against a number of malignancies including Kaposi's sarcoma. Incorporation of doxorubicin into polyethylene glycol-coated (pegylated) liposomes alters the pharmacokinetics of the drug. Liposomal doxorubicin has a smaller volume of distribution and slower plasma clearance than standard free doxorubicin. The liposomal formulation achieves higher concentrations in the highly vascularised lesions of Kaposi's sarcoma than in normal tissue. Liposomal doxorubicin monotherapy in patients with AIDS-related Kaposi's sarcoma produced overall response rates (complete plus partial) of 43 and 59% in large comparative studies and 67 to 100% in noncomparative studies which included > or = 20 patients. In comparative studies, liposomal doxorubicin was significantly more effective than the combination of standard doxorubicin, bleomycin and vincristine (overall response rates of 43 and 25%, respectively) and bleomycin and vincristine (BV) [overall response rates of 59 and 23%, respectively]. In addition, overall response rates to the liposomal drug were higher in both treatment arms of 2 smaller comparative studies which compared liposomal doxorubicin with BV, but significant between-treatment differences were not detected. Patient numbers in these 2 studies, however, may have been too small to detect significant differences. Liposomal doxorubicin is generally well tolerated. Myelosuppression is the most common dose-limiting adverse effect in patients with AIDS and Kaposi's sarcoma. Neutropenia occurs most often; anaemia and thrombocytopenia occur less frequently, as do nausea and vomiting and stomatitis. Palmar-plantar erythrodysaesthesia occurs in some patients, most commonly after 6 to 8 weeks of chemotherapy. Although symptoms may occasionally be severe, the syndrome usually does not require dosage reduction or treatment delay. Limited data suggest that the incidence of cardiotoxicity may be lower after liposomal doxorubicin than after equivalent doses of standard doxorubicin. Overall, liposomal doxorubicin appears to be one of the most active single agents available for treating patients with AIDS-related Kaposi's sarcoma. The therapeutic potential of liposomal doxorubicin administered in combination with other active agents to patients with Kaposi's sarcoma is, as yet, unknown. However, administered alone, the drug seems to be more effective than the best available combination chemotherapy regimens.

The effects of the M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) regimen, which has been reported to improve the outcome of patients with urothelial cancers, were studied on 41 patients treated at our hospital. The patients were divided into adjuvant (24 patients), neoadjuvant (5 patients), and salvage (12 patients) groups. We investigated the dose intensity, the cause-specific survival, response rate and toxicities in the three groups. Although 36 patients received > or = 95% of the initial doses projected, the mean dose intensity (+/-standard deviation) in the adjuvant, neoadjuvant, and the salvage groups was 77 (+/-11), 73 (+/-4), and 74 (+/-12)%, respectively. The five-year cause-specific survival in the adjuvant group was 69% (95% confidence limit: 50-88%). Only 2 of the 5 patients (40%) in the neoadjuvant group survived 23 months after the initiation of the treatment, and all patients in the salvage group died of cancer or treatment-related toxicity within 33 months. The median survival was 38 months in the adjuvant group, 21 months in the neoadjuvant group, and 7 months in the salvage group. A dose intensity > or = 75% did not improve survival in any group. The overall response rate was 33% in 15 patients with evaluable lesions. A complete response was noted in 1 patient and a partial response was noted in 1 patients. Two patients died of treatment-related complications. Nausea and vomiting were observed in all patients. Leukopenia, thrombocytopenia and anemia > or = WHO grade 3 were observed in 25 (61%), 4 (10%), and 7 (17%) patients, respectively. Thrombocytopenia, anemia, and pyrexia > or = grade 3 were seen relatively more often in the patients receiving a dose intensity < 75%. Stomatitis > or = grade 3 appeared to be more frequent in the patients receiving a dose intensity > or = 75%. Adjuvant M-VAC might be beneficial, while its efficacy was limited in the neoadjuvant and salvage settings. Although dose intensity is considered to be important, it did not appear to be related to survival, the response rate, or the toxicity of M-VAC.

We performed a phase II study to evaluate the activity and toxicity of the combination of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin as first-line treatment in patients with recurrent or metastatic head and neck cancer. From March 1994 until August 1996, 49 patients were treated with paclitaxel 200 mg/m2 by 3-hour infusion followed by carboplatin at an area under the concentration-time curve of 7 mg/mL x min; treatment was requested every 4 weeks. Granulocyte colony-stimulating factor was administered prophylactically on days 2 to 12 of each cycle. The study included 41 men and eight women, with a median age of 57 years (range, 23 to 73 years). Most of the patients were symptomatic and had locoregional disease. Primary sites included nasopharynx (14 patients), oropharynx (six), oral cavity (four), hypopharynx (three), larynx (20), paranasal sinuses (one), and unknown (one). After the completion of treatment, four patients (8%; 95% confidence interval, 0% to 16%) achieved a complete response and 12 (24%; 95% confidence interval, 12% to 37%) achieved a partial response. Grade 3/4 toxicities included anemia (2%) and leukopenia, thrombocytopenia, nausea/vomiting, diarrhea, and stomatitis (4% each). After a median follow-up of 15.3 months, median time to progression was 5.7 months (range, 0.5 to 29.8+ months) and median survival was 13.3 months (range, 0.5 to 30.2+ months). In our ongoing study in a similar patient population, gemcitabine was substituted for carboplatin.

The authors, by means of documental research, study the possibility that the physical and psychic symptoms of Vincent van Gogh may have been due to chronic lead poisoning. The technique and materials used by Van Gogh are analysed as the cause of repeated exposure to lead as well as the possible means of penetration of the metal. Through historical-biographical analysis, the progressive symptoms of the illness are compared with those of lead poisoning. The authors conclude that the excessive and continuous use by Van Gogh of pigments which were highly toxic due to their high lead content, such as white lead (lead carbonate) and yellow chrome (lead chromium), could have penetrated his organism by digestive system (primarily) in minimal daily amounts, giving rise to a clinical condition of chronic lead poisoning. This type of poisoning coincides with the clinical symptoms Van Gogh describes in his autographed letters: initial debilitation, stomatitis with loss of teeth, recurring abdominal pains, anaemia (with a "plumbic" skin tone), neuropathy of the radial and saturnine encephalopathy including epileptic crises, progressive character changes and periods of delirium. The clinical symptoms shown by Van Gogh meet present criteria for diagnosis of Organic Mental Disorder due to cerebral lesion or somatic illness (F.06; CIE-10) (DSM-IV-R), and Organic Character Disorder (F.07; CIE-10) (DSM-IV-R).
