The files of 25 patients with propionic acidemia (PA), followed by the Inborn Errors of Metabolism Service (IEMS) at King Faisal Specialist Hospital and Research Centre (KFSH & RC) from 1990 to 1993, were studied retrospectively. In 14 patients PA presented acutely with acidosis, hyperammonemia and thrombocytopenia, while in 11 patients the presentation of the disease was unusual. In the latter group, two neonates with PA initially appeared as a primarily hyperammonemic metabolic disease. In two other neonates the vomiting was so severe that they were diagnosed as intestinal obstruction in referral hospitals. The presentation in three infants was primarily as an immune disorder. In four infants, PA appeared as an acute or chronic encephalopathy, i.e. as a silent organic acidemia, with few other findings of the disease. The clinical picture of PA includes facial and nipple dysmorphia, severe hypotonia and vomiting. Severe thrombocytopenia is the hallmark of the metabolic crisis. In one patient it was noticed late and caused intracranial hemorrhage, while in three others intracranial bleeding caused death. The prognosis in PA remained grave despite rigorous treatment. Only seven of the 25 PA patients remained to have a normal life-style, while eight patients expired. The diagnosis is readily achieved by urine gas chromatography/mass spectrometry (GC/MS), by tandem mass spectrometry (MS/MS), or by enzyme analysis of fibroblasts. While there may be both examiner- and patient-related reasons for the variations in the presentation of PA, one other reason may be the heterogeneity of the molecular defect in propionyl-CoA carboxylase.

Anemia and neutropenia are commonly observed hematologic changes in patients with copper (Cu) deficiency, but thrombocytopenia is rarely found. A-69-year-old patient with postoperative small-bowel obstruction underwent laparotomy three times. Because of persistent obstruction, nasoduodenal suction was continued and total parenteral nutrition was instituted. Fifteen months after the initiation of total parenteral nutrition, the patient gradually developed pancytopenia (red blood cell count 222 x 10(4)/mm3, neutrophil count 1254/mm3, and platelet count 9.2 x 10(4)/mm3). The serum Cu level was 10 micrograms/dL and the serum ceruloplasmin level was less than 5 mg/dL. After 2 weeks of Cu supplementation in a daily dose of 20 mumol, the serum Cu level increased to 81 micrograms/dL and the serum ceruloplasmin level to 20 mg/dL. Hematologic values showed a dramatic response: red blood cell count increased to 362 x 10(4)/mm3, neutrophil count to 4819/mm3, and platelet count to 22.1 x 10(4)/mm3. The improvement of pancytopenia could be attributed to Cu supplementation. This is the first case report of Cu deficiency with pancytopenia during total parenteral nutrition.

Forty patients with locally advanced cervical carcinoma were entered into a protocol utilizing the bolus administration of both mitomycin C (10 or 15 mg) on Day 1 and 5-fluorouracil (400 mg) on Day 1-5 followed by sequential pelvic irradiation on Day 6 between September 1980 and October 1985. All patients had poor-prognosis FIGO stage IB, IIB, IIIB, or IVA disease. Only patients with poor prognosis factors such as bulky tumor masses of 5 cm or greater noted on the initial physical exam (37 patients) or poorly differentiated histology (3 patients) were eligible for this study. There were three severe side effects seen in the 24 patients receiving 15 mg mitomycin C. One patient developed thrombocytopenia, one patient developed acute radiation enteritis, and the third patient developed radiation proctitis requiring laser therapy. Only 1 of 16 patients receiving 10 mg mitomycin C developed a complication (thrombocytopenia). Neutropenia was mild in all patients. No infections were seen. Thrombocytopenia never warranted platelet transfusion. No patients developed therapy-related bowel obstruction or fistulae. Median follow-up was 11.3 years with a range of 6.2-14.2 years. A complete response rate of 63%, a local control rate of 58%, and a 5-year survival rate of 44% were obtained. This does not appear to offer any benefit over radiation alone. This present study supports the superiority of higher dose concurrent infusional chemotherapy and radiation over low-dose sequential bolus chemotherapy and radiation.

Complicated small-bowel diverticula cause abdominal pain, gastrointestinal hemorrhage, small-bowel obstruction, and peritonitis. The present patient, had an occult perforation of a small-bowel diverticulum. There were diverticula throughout the whole small bowel. Preoperatively thrombocytopenia (98,000 thrombocytes/cc), was noted. Without any special treatment, i.e., transfusion, the thrombocyte level increased after surgical treatment to normal levels. Although the incidence of small-bowel diverticula appears to be low (0.1%-2.3%) complications may become life-threatening. The level of thrombocytopenia may reflect the extent of inflammation.

The purpose of this study is to retrospectively evaluate the efficacy and toxicity of whole abdominopelvic irradiation (WAI) in patients with persistent or recurrent epithelial ovarian carcinoma who failed chemotherapy. Between 1970 and 1995, 41 women with persistent or recurrent ovarian carcinoma after initial treatment with surgical debulking and chemotherapy (4 to 18 cycles; median, 8) were treated with WAI. Thirty-one patients had received platinum-based regimens, and 22 of these had failed within 6 months after completion of chemotherapy ("platinum-refractory"). Prior to WAI, 11 (27%) patients had microscopic residual disease, 21 (51%) had gross residual disease up to 1.5 cm, and 9 (22%) had residual tumors greater than 1.5 cm in maximal diameter. Median doses of 28 Gy to the abdomen and 48 Gy to the pelvis were delivered using open-field techniques and liver and kidney shielding. With follow-up of 1 month to 16.5 years (median potential follow-up, 1.4 years), the 5-year actuarial disease-specific survival was 47% in all 41 patients, and 50% in the 22 platinum-refractory patients. Both residual tumor size at WAI (P < 10(-4)) and initial stage (P = 0.003) were of prognostic value. Five-year disease-specific survival of all patients with residual tumors less than 1.5 cm was 53%; 0% for patients with tumors greater than 1.5 cm. Five-year disease-specific survivals by initial stage were: stage I and II, 75%; stage III, 40%; and stage IV, 15%. Stage I, II, or III patients with residual disease up to 1.5 cm before WAI had a 10-year actuarial disease-specific survival of 40%. Twelve patients (29%) failed to complete the planned course of WAI due to acute toxicity (most often due to prolonged thrombocytopenia). Late toxicity (requiring surgery) included bowel obstruction in two patients and fistula in one patient. Whole abdominopelvic irradiation should be considered in selected patients who fail initial chemotherapy, especially in patients who can or have been debulked to small amounts of residual disease. With acceptable toxicity, WAI results appear to be as good as or better than second-line chemotherapy, particularly in platinum-refractory patients.

A phase II study to evaluate the efficacy and toxicity of the combination of vinblastine, paclitaxel and cisplatin (PVC) in previously untreated patients with advanced transitional cell carcinoma. Chemotherapy naive patients with locally advanced or metastatic transitional cell carcinoma received the intravenous combination of paclitaxel 175 mg/m(2)over three hours followed by cisplatin 70 mg/m(2)over 3 hours on day 1 and vinblastine 3 mg/m(2)as a bolus on days 1 and 8 on a 21-day cycle, to a maximum of 6 cycles. The day 8 vinblastine was omitted if the total neutrophil count was <1.0. 15 patients (13 M, 2 F) of median age 66 (54-75) received a median of 5 cycles of treatment. There were two complete responses (13%; 95% CI 2-40%) and five partial responses (33%; 95% CI 12-62%), for an overall response rate of 46% (95% CI 21-73%). Responses occurred only in those with locally recurrent tumours and/or lymph nodes involved. Neutropenia at Grade 3-4 occurred in 14 of 67 cycles (21%) resulting in 7 episodes of neutropenic sepsis. Grade 3-4 thrombocytopenia was not observed. Other Grade 3 toxicity included alopecia (10 pts), diarrhoea (2 pts), constipation resulting in bowel obstruction (2 pts), nephrotoxicity (1 pt), myalgic pain (1 pt) and peripheral neuropathy (1 pt). Six patients developed Grade 2 paraesthesia. The median time to progression was 6 months and the median survival was 11 months. The regimen PVC was both less effective against transitional cell carcinoma and less toxic than expected. This may reflect an inhibitory interaction between vinblastine and paclitaxel and this schedule cannot be recommended for further investigation.

The aim of this study was to determine whether the addition of whole body hyperthermia (WBH) to carboplatin (CBDCA) can induce responses in patients with platinum-resistant ovarian cancer. 16 pretreated patients with platinum-resistant ovarian cancer were entered on a Systemic Hyperthermia Oncological Working Group (SHOWG) study; (14 patients were eligible with 14 evaluable for toxicity and 12 for response). The patients were treated with WBH (Aquatherm) 41.8 degrees C x 60 min in combination with carboplatin (CBDCA) (area under the curve (AUC) of 8) every 4 weeks. Disease status was evaluated every two cycles. Patients were treated for a maximum of six cycles. One patient had a complete response (CR) and 4 had a partial response (PR). 4 patients had stable disease (SD). 3 patients had progressive disease (PD). 2 patients were unevaluable: 1 had a bowel obstruction shortly after her first treatment; the second patient achieved a CR, but only had one treatment secondary to an idiosyncratic reaction to sedative drugs. 2 patients entered on study were ineligible, as they did not meet criteria for platinum resistance; 1 entered a CR and 1 had SD. Dose-limiting toxicity, which required CBDCA dose reductions, was grade 4 thrombocytopenia. Other toxicities included neutropenia (grade 3/4), and nausea and/or vomiting. Consistent with preclinical modelling, these results suggests that 41.8 degrees C WBH can overcome platinum resistance in ovarian cancer. These observations suggest further investigation of the therapeutic potential of WBH in a group of patients who historically fail to respond to salvage therapies is warranted.

A 59-year-old man with a six-month history of chronic myelomonocytic leukemia (CMML) was admitted to the Kitasato University Hospital because of melena in September 2000. Colonofiberscopy and barium enema demonstrated an ulcerated tumorous lesion in the transverse colon. The histopathologic findings of the ulcer bed revealed diffuse infiltration of granulocytes at each stage of differentiation. The diagnosis of granulocytic sarcoma (GS) was made. Surgical resection was not indicated, because thrombocytopenia was hardly improved enough to allow surgery despite repetitive transfusion of platelet concentrates. CMML developed to refractory anemia with excess of blast in transformation in February 2001. Two courses of low dose cytarabine plus aclarubicin were ineffective on the GS in spite of a decrease in the peripheral blood blasts. Progression to acute myeloid leukemia eventually broke out, in July 2001. The patient died of leukemia complicated with pneumonia and intestinal obstruction. At present, nine cases of GS in the colon have been reported. However, these cases did not include CMML. This is the first report describing GS in the colon associated with CMML.

A palliative combination chemotherapy regimen (FaFEC) was developed for patients with relapsed epithelial ovarian cancer in particular patients relapsing after, or ineligible to enter, phase II trials, usually due to lack of evaluable disease. Forty-six patients were enrolled. Patients had received a mean of 2.3 previous drug regimens and nine (19%) had intestinal obstruction at the start of FaFEC. The majority of patients were inevaluable by WHO criteria so objective response data was obtained from serial serum CA125 evaluations. A serological response was demonstrated in 8/44 (18%). The responders included 6/27 women who had a prior relapse-free interval of less than 3 months, four who were resistant to platinum chemotherapy and three patients who had previously received paclitaxel. The major (WHO grade 3/4) toxicities included leucopenia (six patients), anemia (three patients), thrombocytopenia (two patients), nausea and vomiting (four patients) and severe infections (five patients). Following FaFEC the median time to failure was 0.48 years and the median survival was 0.66 years. FaFEC was effective in this group of very poor prognosis patients. The serological response rate of 18% is noteworthy considering the multiple prior treatments that patients had received and the short treatment free intervals. FaFEC may be useful second line therapy in epithelial ovarian cancer patients ineligible for phase II studies and should be considered for a randomized comparison with paclitaxel.

In this report, we present a six-year-old male patient with partial intestinal obstruction due to refractory Non-Hodgkin's lymphoma (NHL) whose partial obstruction was successfully treated with Taxol(R) without any surgical intervention. Following an unsuccessful treatment attempt to treat his high-grade (stage 3) B-cell lymphoma with standard and second-line chemotherapy regimens he was started on radiotherapy and third line chemotherapy during which he was admitted with partial obstructive ileus as a result of tumor progression. Treatment was continued with Taxol(R) and resulted in total cure of the ileus with reduction of palpable tumor mass over 24 h without necessitating any surgery. Taxol(R) (200 mg/m (2)/week) was administered without any major side effects/toxicities for six courses. A control CT of the abdomen revealed a significant reduction in tumor size. After the next course, the patient developed severe thrombocytopenia that unfortunately did not resolve before the patient died as a result of further tumor growth and dissemination. Although there are studies that report response to Taxol(R) treatment in adult patients with refractory NHL, our review of the literature failed to demonstrate any report about the effectiveness of Taxol(R) in childhood NHL. In conclusion, our case may indicate that Taxol(R) can be effective and be administered safely in an outpatient setting in children with refractory NHL with the aim of prolonging the survival without sacrificing good quality of life. Studies on larger number of patients are needed to make a definitive conclusion about the value of Taxol(R) in refractory childhood NHL.
