Forty Japanese patients with primary malignant tumors of the small intestine were reviewed. Adenocarcinoma was the most common tumor type comprising 19 patients (47%), followed by malignant lymphoma, 11 (30%), leiomyosarcoma, 8 (20%) and carcinoid tumor, 1 (3%). Adenocarcinomas and leiomyosarcomas were primarily located in the duodenum or jejunum, whereas lymphomas were more common in the jejunum or ileum. Abdominal pain (65%) and nausea or vomiting (35%) were the most common symptoms with these tumors. Barium contrast studies were able to detect 83% of these tumors. Our results also suggest that computed tomography and ultrasonography are not reliable for diagnosing jejunal tumors while superior mesenteric angiography is effective for diagnosing ileal tumors. The duodenal and ileal tumors tended to metastasize to lymph nodes while jejunal ones tended to penetrate the serosa or to disseminate into the peritoneal cavity. The percentage of tumors potentially cured by surgery and the 5 year survival rates of the leiomyosarcomas (75% and 57%, respectively) were higher than those of adenocarcinomas (42% and 10%, respectively) and lymphomas (42% and 32%, respectively).

A Phase I study of intravenous (IV) bolus 4'-0-tetrahydropyranyladriamycin (Pirarubicin) was done in 55 patients in good performance status with refractory tumors. Twenty-six had minimal prior therapy (good risk), 23 had extensive prior therapy (poor risk), and six had renal and/or hepatic dysfunction. A total of 167 courses at doses of 15 to 70 mg/m2 were evaluable. Maximum tolerated dose in good-risk patients was 70 mg/m2, and in poor-risk patients, 60 mg/m2. The dose-limiting toxic effect was transient noncumulative granulocytopenia. Granulocyte nadir was on day 14 (range, 4-22). Less frequent toxic effects included thrombocytopenia, anemia, nausea, mild alopecia, phlebitis, and mucositis. Myelosuppression was more in patients with hepatic dysfunction. Pharmacokinetic analyses in 21 patients revealed Pirarubicin plasma T 1/2 alpha (+/- SE) of 2.5 +/- 0.85 minutes, T beta 1/2 of 25.6 +/- 6.5 minutes, and T 1/2 gamma of 23.6 +/- 7.6 hours. The area under the curve was 537 +/- 149 ng/ml x hours, volume of distribution (Vd) 3504 +/- 644 l/m2, and total clearance (ClT) was 204 + 39.3 l/hour/m2. Adriamycinol, doxorubicin, adriamycinone, and tetrahydropyranyladriamycinol were the metabolites detected in plasma and the amount of doxorubicin was less than or equal to 10% of the total metabolites. Urinary excretion of Pirarubicin in the first 24 hours was less than or equal to 10%. Activity was noted in mesothelioma, leiomyosarcoma, and basal cell carcinoma. The recommended starting dose for Phase II trials is 60 mg/m2 IV bolus every 3 weeks.

The records of patients with primary gastric lymphoma and sarcoma treated at M. D. Anderson Hospital and Tumor Institute between 1945 and 1975 were reviewed. Weight loss, abdominal pain, nausea, and vomiting were the most common presenting symptoms, while palpable abdominal mass was the most common sign. The lymphomas were predominantly located in the distal portion of the stomach, in contrast to the sarcomas, which were commonly located in the body and the proximal portion of stomach. Curative gastric resection was performed in 96% of patients with lymphoma and in 67% of patients with sarcoma. Diffuse histiocytic lymphoma and leiomyosarcoma were the most common histologic types. Patients with lymphoma survived significantly longer than patients with sarcoma (median 75 vs 22 months, P = 0.009). Adjuvant radiotherapy seemed to improve the survival of patients with lymphoma, while curative gastric resection provided the only hope for long-term survival for patients with gastric sarcoma. The place of adjuvant chemotherapy after curative resection of gastric lymphoma and sarcoma remains to be investigated.

Methyl-GAG was given to 71 patients with advanced malignancies as a weekly brief infusion (30-120 minutes) or as a biweekly 24- or 120-hour infusion. Mucositis (stomatitis, pharyngitis, esophagitis, and, rarely, inflammation of other mucous membranes) was dose-limiting in all three schedules. Generalized fatigue, malaise, myalgia, dysesthesias, nausea, and vomiting were more frequent in the brief-infusion schedule. Myelosuppression was mild and not dose-related. Fever, ventricular arrhythmias, skin rash, tender swelling of the palms, neuropathy, and paralytic ileus were rare. Toxicity was increased in patients with renal insufficiency or "third-space" fluid but was not increased by hepatic dysfunction. Cumulative and overlapping toxicity was evident only in the weekly schedule. Higher doses of methyl-GAG were tolerated when the duration of infusion was increased. The recommended doses for phase II trials are 700 mg/m2 weekly as a 1-2 hour infusion, 850 mg/m2/24 hours biweekly, and 1500 mg/m2/120 hours biweekly. Therapeutic effects were seen in all schedules and included objective responses in colon carcinoma (one of 13 patients), renal cell carcinoma (one of nine), and Hodgkin's lymphoma (one of two) and objective improvements in esophageal carcinoma (one of three), endometrial carcinoma (two of two), and leiomyosarcoma (one of three).

Ifosfamide is an active chemotherapeutic agent in the treatment of soft tissue sarcoma. This Phase II study attempted to evaluate the efficacy of the addition of etoposide to ifosfamide administered to patients with recurrent or metastatic soft tissue sarcoma. Treatment consisted of etoposide 100 mg/m2, followed by ifosfamide 2.0 g/m2, daily, for 4 consecutive days. Mesna was administered for uroprotection. Cycles were repeated at 21-day intervals or upon recovery from toxicity. Two partial responses were observed in 19 evaluable patients (response rate 10.5%, 95% confidence interval, 7% to 14%). Response durations were brief at 2 and 6 months. In a subset of 10 patients with gastrointestinal leiomyosarcoma, no responses were observed. Toxicity was generally mild, consisting primarily of myelosuppression and controllable nausea and emesis. No episodes of hematuria were observed. Overall survival for all eligible patients was 10 months (range: 0.2 to 34.7+ months). Etoposide, in this dose and schedule, failed to enhance the activity of ifosfamide in adult soft tissue sarcoma. Additionally, this experience and a review of the literature, suggest that ifosfamide has little activity against gastrointestinal leiomyosarcomas. Continued efforts are needed to identify novel agents with efficacy against these resistant tumors.

Leiomyosarcoma is the second most common non epithelial malignant tumor of the stomach. It is almost always a single lesion. Multiple leiomyosarcomas of the stomach are extremely rare. To our knowledge only three cases have been reported so far. We present a 40 year old female with epigastric pain, nausea, diarrhea, weight loss and melena in whom we diagnosed multiple lesions of the stomach. At operation, we found a total of 11 submucosal or subserosal lesions ranging in size from 0.5 to 6 cm in diameter localized throughout the stomach. Histological examination showed leiomyosarcoma in every lesion. Almost all the lymph nodes along curvatures had metastases. Other lymph nodes, peritoneum, liver and other organs were disease free. A total gastrectomy and Roux-en-Y esophagojejunostomy was performed. She had an uneventful recovery and has remained symptom-free so far (nine months).

A 49-year-old woman was referred to our hospital with complaints of epigastric colicky pain and high fever. Abdominal computed tomography and ultrasonography showed a solid tumor in the lower abdomen. Laparotomy revealed a neoplastic mass arising in Meckel's diverticulum; therefore, a segment of the ileum, including the tumor-possessing diverticulum, was resected with a lymph node dissection. A histologic examination confirmed the lesion to be leiomyosarcoma. In the English literature, 59 cases of leiomyosarcoma in Meckel's diverticulum were reported from 1941 to 1994. The majority of patients were in their 4th decade of life, with both sexes equally affected. The most frequent symptoms associated with this disease were abdominal pain with nausea, vomiting, and melena. The majority were larger than egg-size. Although Meckel's diverticulum is difficult to diagnose preoperatively, mesenteric arteriography may at times prove useful. The standard management of this particular tumor is wide segmental resection, including the tumor and diverticulum with lymph node dissection.

We describe herein a very rare case of leiomyosarcoma arising in the lesser sac. A 58-year-old man with a psychiatric disorder was admitted to our department for the investigation of epigastralgia and nausea which he had been suffering since the previous month. A laparotomy revealed that the abdominal mass, found on physical examination, was a primary lesser omental tumor, histological examinations of which confirmed a diagnosis of leiomyosarcoma. The tumor cells showed a DNA diploid pattern. Leiomyosarcoma of the lesser sac is extremely unusual and it is important that it be distinguished from an extraluminal tumor of the abdomen.

Small bowel tumors (SBT) are rare neoplasms and represent less than 10% of all gastrointestinal tumors. The majority of them are benign and discovered at the time of autopsy. However of those who present symptoms the majority belong to the group of malignant tumors and require of treatment. The most common histological variety are the adenocarcinoma and the carcinoid tumors. Abdominal pain, intestinal obstruction or gastrointestinal bleeding are the most common clinical complaints. Endoscopy or contrast X-ray examination are the most common forms of diagnosis and surgery remain the best way of treatment chemotherapy or radiotherapy are used in combination with surgery according to the histological diagnosis, the survival depends to the final histological report. A review of the experience at the National Institute of Cancer in Mexico city was performed and 34 patients were found with the diagnosis of SBT of which the majority presented with abdominal pain, nausea, vomiting and abdominal distension. The most common histological diagnosis were the adenocarcinoma (52%) and the leiomyosarcoma (32%). Surgery was the most common form of treatment (73%) of which in 20% distant metastasis was diagnosed. Only nine are alive at the time of the report without recurrent disease with a mean follow up of 7 months. Our experience shows that SBT are rare neoplasms, the majority are diagnosed late but surgery remain the best way of treatment because it can offer the possibility of cure or adequate palliation with derivative procedures.

Temozolomide (TMZ) is an oral imidazotetrazinone that is spontaneously converted to 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC) at physiological pH. MTIC methylates DNA at the O6 position of guanine, although this lesion may be repaired by the enzyme O6-alkylguanine-DNA alkyltransferase (AGAT). In this study, TMZ was combined with cisplatin (CDDP), because both agents have single-agent activity against melanoma and other tumor types. Additionally, CDDP has been shown to inactivate AGAT, and subtherapeutic concentrations of CDDP have been shown to increase the sensitivity of leukemic blasts to TMZ. This Phase I study sought to determine the toxicities, recommended dose, and pharmacological profile of the TMZ/CDDP combination. Patients were treated with oral TMZ daily for 5 consecutive days together with CDDP on day 1 (4 h after TMZ) every 4 weeks at the following TMZ (mg/m2/day)/CDDP (mg/m2) dose levels: 100/75, 150/75, 200/75, and 200/100. Plasma samples were obtained on days 1 and 2 to evaluate the pharmacokinetic parameters of TMZ alone and in combination with CDDP. Fifteen patients received a total of 44 courses of TMZ/CDDP. The principal toxicities of the regimen consisted of neutropenia, thrombocytopenia, nausea, and vomiting, which were intolerable in two of six new patients treated at the 200/100 mg/m2 dose level. Of five patients receiving 17 courses at the next lower dose level (200/75 mg/m2), none experienced dose-limiting toxicity. Antitumor activity was observed in patients with non-small cell lung cancer, squamous cell carcinoma of the tongue, and leiomyosarcoma of the uterus. Pharmacokinetic studies of TMZ revealed the following pertinent parameters (mean +/- SD): time to maximum plasma concentration (Tmax) = 1.1+/-0.6 h (day 1) and 1.7+/-0.9 h (day 2); elimination half-life (t1/2) = 1.74+/-0.22 h (day 1) and 2.35+/-0.70 h (day 2); and clearance (Cl(s)/F) = 115+/-27 ml/min/m2 (day 1) and 141+/-109 ml/min/m2 (day 2). TMZ drug exposure, described by the area under the plasma concentration-time curve (AUCinfinity) and the maximum plasma concentration (Cmax), was similar on days 1 and 2. On the basis of these results, the recommended doses for Phase II clinical trials are TMZ 200 mg/m2/day for 5 days with 75 mg/m2 CDDP on day 1, every 4 weeks. The addition of CDDP did not affect the tolerable dose of single-agent TMZ (200 mg/m2/day x 5 days), nor did it substantially alter the pharmacokinetic behavior of TMZ.
